    For successful human placentation, invasion of trophoblast cells into the uterus and its associated vasculature is essential, and the regulation of this process is controlled by many factors at the fetal-maternal interface. N-acetylglucosaminyltransferase V (GnT-V) is a key enzyme that catalyzes beta1, 6-N-acetylglucosamine (beta1-6GlcNAc) branching on asparagine-linked oligosaccharides of cell proteins. GnT-V and its product, beta1-6GlcNAc, are known to regulate cellular transformation and correlate with the metastatic potential of various cancer cells. The aim of the present study was to determine whether extravillous trophoblast (EVT) expressed this molecule and examine the role of GnT-V in the regulation of human trophoblast invasion. Immunohistochemistry showed that GnT-V was strongly expressed within the cytoplasm of EVT in the anchoring villi; this expression was down-regulated in EVTs invading the decidua. Suppression of beta1-6GlcNAc glycosylation by swainsonine enhanced the migratory potential and invasive capability of both primary EVTs and the EVT cell line, HTR-8/SVneo. Down-regulation of GnT-V expression by small interfering RNA in the choriocarcinoma cell line Jar consistently enhanced the migration and invasive capacity of these cells and elevated cellular adhesion to extracellular matrix proteins, such as fibronectin and collagen type I/IV. The extent of beta1-6 branching of alpha5beta1 integrin was significantly reduced in small interfering GnT-V-transfected Jar cells compared with mock transfectants, although the expression of alpha1, alpha5, alpha6, and beta1 integrin on the cell surface was not changed. These results suggest that GnT-V is expressed in human EVT and is involved in regulating trophoblast invasion through modifications of the oligosaccharide chains of alpha5beta1 integrin.

    The transcriptional factor Ikaros was originally found to function as a key regulator of lymphocyte differentiation. In addition, we have reported that Ikaros regulates the human placental leucine aminopeptidase (P-LAP)/insulin-regulated aminopeptidase (IRAP) gene in choriocarcinoma trophoblastic cells, suggesting that Ikaros might be involved in placental development, while even its presence in human placenta remains undetermined. We therefore sought to clarify the location and roles of Ikaros in human placenta. Immunohistochemical analysis showed modest Ikaris expression in syncytium, and intense expression in extravillous trophoblasts (EVTs) in first trimester placenta. Western blot analysis showed that villous trophoblasts principally expressed Ikaros-2/3, while Ikaros-x (Ikx) was predominantly expressed in cultured EVTs. Furthermore, to investigate the functional role of Ikx in EVTs, the EVT cell line HTR-8/SVneo was infected with a retrovirus vector expressing the hemagglutinin (HA)-tagged dominant negative isoform Ikaros-6 (Ik6), which prevents the DNA-binding activity of Ikx. Antibody against HA showed successful transduction of Ik6 in HTR-8/SVneo cells on immunocytochemistry and Western blotting. Transduction of Ik6 significantly reduced the migratory and invasive abilities of HTR-8/SVneo cells. These results suggest that Ikx is involved in migration and invasion of EVTs in early placentation.

    N-acetylglucosaminyltransferase V (GnT-V) is an enzyme that catalyses beta1-6 branching of N-acetylglucosamine on asparagine-linked oligosaccharides of cell proteins. The present study aimed to investigate GnT-V expression and its prognostic significance in endometrial cancer. N-acetylglucosaminyltransferase V expression was studied by immunohistochemistry in 74 surgically resected endometrial cancers, and the staining intensity was evaluated. High GnT-V expression in tumour cells was found in 43 (58.1%) of the 74 cases, and was positively correlated with advanced patient age, histological grade, and lymph vascular space involvement. Patients with high GnT-V expression had significantly impaired overall survival and progression-free survival (PFS) (P=0.0041 and P=0.0023, respectively) compared to patients with low expression of GnT-V. On multivariate analysis, GnT-V expression was an independent prognostic factor for PFS (P=0.0364). beta1-6 branching of asparagine-linked oligosaccharides was also detected in GnT-V-positive endometrial cancer cells by leukoagglutinating phytohaemagglutinin (L(4)-PHA) staining, and the molecular size of the major glycoproteins recognised by L(4)-PHA was approximately 60-200 kDa by lectin blot analysis. These results suggested that high GnT-V expression was correlated with an unfavourable clinical outcome, and that GnT-V is involved in the malignant potential of endometrial cancer by increasing the synthesis of beta1-6 branching of asparagine-linked oligosaccharides.

    Nongestational pure choriocarcinoma of the ovary is a very rare germ cell tumor. Except in women before menarche, determination of the origin is very difficult without genetic analysis. We present a pure nongestational choriocarcinoma arising in the left ovary of a 19-year-old woman. Following surgery, pathologic findings of the tumor demonstrated pure choriocarcinoma without combination of other germ cell tumor elements. We confirmed its nongestational origin by DNA polymorphism analysis at 15 short tandem repeat loci. Multiple courses of chemotherapy with methotrexate, etoposide, and actinomycin-D were effective for this case. DNA polymorphism analysis is useful to determine genetic origin in pure choriocarcinoma of the ovary.

    The reduced migration/invasion of extravillous trophoblasts (EVTs) is a key feature of the genesis of preeclampsia. We and others previously reported that transcriptional factors activator protein-2 (AP-2) alpha and AP-2gamma act as suppressors of tumor invasion. The present study examined the expressions of AP-2alpha and AP-2gamma in preeclamptic placenta vs. control placenta and investigated their effect on the function of EVTs. The expressions of AP-2alpha and AP-2gamma were elevated in the preeclamptic placentas in comparison with the gestational age-matched control placentas. Their expressions also increased in EVTs of the preeclamptic placentas. Thereafter, we transfected AP-2alpha or AP-2gamma into human EVT cell line, HTR-8/SVneo. The overexpression of AP-2alpha or AP-2gamma decreased the migratory and invasive abilities in HTR-8/SVneo cells. This was followed by the reduction of protease activated receptor-1 and matrix metalloproteinases and a significant induction of plasminogen activator inhibitor-1 and the tissue inhibitor of metalloproteinase-1. AP-2alpha and AP-2gamma were weakly expressed in the cultured EVTs and HTR-8/SVneo cells, whereas they were induced by TNF-alpha, which increases in preeclamptic placenta and impairs trophoblast invasion. In the presence of TNF-alpha, the invasion of the HTR-8/SVneo cells was partially restored by a blocking of AP-2 induction using small interfering RNA of AP-2. The present data suggest that AP-2 may suppress trophoblast migration and invasion, thus leading to a shallow placentation in preeclampsia.

    N-acetylglucosaminyltransferase V (GnT-V) is an enzyme that catalyzes beta1-6 branching of N-acetylglucosamine (GlcNAc) on asparagine-linked oligosaccharides of cell proteins. The present study aimed to investigate GnT-V expression and its prognostic significance in epithelial ovarian cancer. GnT-V expression was studied by immunohistochemistry in 83 surgically resected ovarian cancers, and the staining intensity was evaluated. High GnT-V expression in cancer cells was found in 17 (20.5%) of the 83 cases, and was positively correlated with early FIGO staging. In the histological type, mucinous adenocarcinoma showed significantly strong immunostaining compared to the non-mucinous type (P<0.001). In 36 mucinous tumors, the GnT-V immunostaining score was significantly higher in cancer than in benign and borderline tumors (P<0.001). NOM-1, a human ovarian mucinous adenocarcinoma cell line, expressed strong GnT-V protein and swainsonine treatment suppressed beta1-6GlcNAc branching and reduced migration ability significantly (P<0.001). These results suggested that GnT-V might be involved in the malignant potential of mucinous ovarian cancer.

    BACKGROUND/AIMS: In the present study, we investigated the participation of inflammatory cytokine-induced mediated matrix metalloproteinase (MMP) expressions and inhibition of interleukin (IL)-6-induced MMP secretion in amniotic epithelial cells by tocilizumab. METHODS: To investigate the role of MMP expressions, immunohistochemical staining was performed using membranes obtained from 10 patients with preterm premature rupture of membranes (PPROM) and from 10 patients who underwent a nonlabor cesarean section. We also investigated the regulation of MMP expression by inflammatory cytokines in human amnion cells. RESULTS: Immunohistochemical staining showed a significantly higher expression of MMP-2 and -9 in PPROM. Treatment of cultured WISH and primary amniotic epithelial cells with 10(-8) or 10(-7)M IL-6 or tumor necrosis factor (TNF)-alpha clearly increased the secretion of MMP-2 and -9. Treatment with 10(-8)M TNF-alpha or IL-6 significantly increased the invasion of WISH or primary amniotic epithelial cells, respectively, compared with the control. At a low concentration of 1 microg/ml, tocilizumab (anti-human IL-6 receptor monoclonal antibody) inhibited the IL-6-induced MMP secretion. CONCLUSIONS: This paper is the 1st report of tocilizumab inhibiting IL-6-induced MMP-2 and MMP-9 secretions from human amnion cells in PPROM.

    A high infant mortality rate (IMR) indicates a failure to meet people's healthcare needs. The IMR in Lao People's Democratic Republic has been decreasing but still remains high. This study aimed to identify the factors involved in the high IMR by analyzing data from 53,727 live births and 2189 women from the 2017 Lao Social Indicator Survey. The estimated IMR decreased from 191 per 1000 live births in 1978-1987 to 39 in 2017. The difference between the IMR and the neonatal mortality rate had declined since 1978 but did not change after 2009. Factors associated with the high IMR in all three models (forced-entry, forward-selection, and backward-selection) of multivariate logistic regression analyses were auxiliary nurses as birth attendants compared to doctors, male infants, and small birth size compared to average in all 2189 women; and 1-3 antenatal care visits compared to four visits, auxiliary nurses as birth attendants compared to doctors, male infants, postnatal baby checks, and being pregnant at the interview in 1950 women whose infants' birth size was average or large. Maternal and child healthcare and family planning should be strengthened including upgrading auxiliary nurses to mid-level nurses and improving antenatal care quality.

    Postpartum depression is a worldwide public health concern. The prevalence of postpartum depression is reported to be greater in developing countries than in developed countries. However, to the best of our knowledge, no papers on postpartum depression in the Lao People's Democratic Republic have been published. In order to strengthen maternal and child health, the current situation of postpartum depression should be understood. This study aims to determine the prevalence of postpartum depression and identify factors associated with postpartum depression in Vientiane Capital, Lao People's Democratic Republic. Study participants were 428 women 6-8 weeks postpartum who visited four central hospitals in Vientiane Capital for postnatal care from July to August 2019. Structured questionnaires were used to collect socio-demographic, obstetrical and infant, and psychiatric data about the women and their partners. The Edinburgh Postnatal Depression Scale (EPDS) was used to identify suspected cases of postpartum depression with the cut-off score of 9/10. Multivariable logistic regression was used to examine independent factors that were associated with suspected postpartum depression (EPDS ≥10). The mean age of the 428 women was 28.1 years, and the prevalence of suspected postpartum depression was 31.8%. Multivariable logistic regression using variables that were statistically significant on bivariate analyses indicated that three variables were associated with suspected postpartum depression: unintended pregnancy (AOR = 1.66, 95% CI 1.00-2.73, P = 0.049), low birth satisfaction (AOR = 1.85, 95% CI 1.00-3.43, P = 0.049), and depression during pregnancy (AOR = 3.99, 95% CI 2.35-6.77, P <0.001). In this study, unintended pregnancy, low birth satisfaction, and depression during pregnancy were independent risk factors for postpartum depression. These results suggest that the mental health of pregnant women should be monitored, and that health care services, especially family planning and supportive birth care, should be strengthened to prevent postpartum depression.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for treating pain and inflammation. Spontaneous adverse drug reaction (ADR) reports represent a rich data source for the detection of unknown and rare ADRs. This cross-sectional study aimed to analyze the characteristics of ADRs due to NSAIDs in Thailand. All ADR reports of NSAIDs for systemic use from 2015 to 2019 were extracted from the national database in Thailand. Patient characteristics, drug use information, adverse event information, and source of senders in 32,857 reports were analyzed. The annual number of ADR reports due to NSAIDs decreased from 7,008 in 2015 to 5,922 in 2019. The most frequently reported drug was ibuprofen (n=12,645, 38.5%) followed by diclofenac (n=7,795, 23.7%), most patients were 40-59 years old, and the major adverse reaction was angioedema (n=7,513, 22.9%). Serious reactions were recorded in 20.7% (n=6,801) of the total ADRs. Most patients (n=20,593, 62.7%) recovered without sequelae, but there were 5,420 patients (16.5%) who could not recover and 3,109 patients (9.5%) who were recovering. Eight patients (0.02%) died of Stevens-Johnson syndrome (n=3), toxic epidermal necrolysis (n=4), and anaphylactic shock (n=1), which were possibly related to ADRs. The number of ADR reports due to NSAIDs decreased from 2015 to 2019 in Thailand. Serious ADRs and death cases accounted for 20.7% and 0.02%, respectively. Most fatal cases exhibited severe drug-induced skin reactions.

    Period shaming is defined as any negative and/or disrespectful behavior in relation to the menstrual cycle and menstruating girls. It is suggested that period shaming may limit girls' potential and ability to fully participate in school and community activities. This study aims to examine the prevalence and factors associated with period shaming among male students in Luang Prabang Province, Lao People's Democratic Republic (Lao PDR). This was a cross-sectional study which was conducted during November 19-27, 2020. This study included 1,232 male students from secondary school grade 9 to 12 in Luang Prabang Province, Lao PDR. Informed consent was obtained from the participants, parents/guardians, and teachers prior to data collection. The data was collected by a self-administered questionnaire. Logistic regression was employed to examine factors associated with period shaming behavior among male students. The mean age of the participants was 16.4 years old. Of all the male students, 18.8% admitted that they had shamed girls during their menstruation at least once. Of those who committed period shaming, they shamed girls some of the times (63.2%). Male students who had consumed alcohol during the last month before the data collection day (AOR = 1.83, 95% CI 1.32-2.55, P<0.001), had heard of menstruation (AOR = 1.76, 95% CI 1.27-2.44, P<0.001), and those who had attended activities/classes about sexual reproductive health (AOR = 1.90, 95% CI 1.29-2.78, P<0.01), were significantly associated with period shaming behavior. In conclusion, a single focus on providing biological health education may not be enough to address menstrual stigmatization and taboos. The school curriculum should integrate other life skill education with reproductive health, such as respect and gender equality, to encourage behavioral changes among male students, to address menstrual stigma and to support and empower girls' menstrual health at school and in the community.

    OBJECTIVE: The maternal mortality ratio (MMR) in Myanmar was the highest in Southeast Asia in 2017. The Three Delay Model is used to evaluate delays that contribute to maternal deaths. This study aims to identify MMR, causes of death, the three delays related to maternal deaths, and the factors associated with Delay 1, which is the time of delay in deciding to seek health care (from the start of the woman's illness to the time when the problem is recognized to be requiring care), in Myanmar. STUDY DESIGN: A cross-sectional study. PARTICIPANT: This study included 934 cases of maternal deaths reported from all states and regions throughout Myanmar in 2019 that were not caused by accidents and injuries. MATERIALS AND METHODS: Socio-demographic factors, obstetrical factors, information about deaths, and assessment of delays were obtained from the Maternal Death Surveillance and Response System, the database of maternal deaths. Distribution of maternal deaths by states and regions, causes of maternal death, and types of delay that contributed to maternal deaths were descriptively summarized. Logistic regression analysis was performed to identify factors associated with Delay 1 among 567 maternal deaths without any missing data and unknown information on delays. FINDINGS: In 2019, the MMR was 106 (95% confidence interval, 99-112) per 100,000 live births. Of the 934 maternal deaths, 80.5% of deaths had at least one delay, and Delay 1 was the major delay (72.9%). Eclampsia/pre-eclampsia (21.6%), postpartum hemorrhage (18.2%), and abortion-related complications (13.2%) were the major causes of maternal death. The husband's low education, low household income, unplanned pregnancy, and no antenatal care were associated with Delay 1. KEY CONCLUSIONS AND IMPLICATION FOR PRACTICE: The MMR was lower in 2019 than that in 2017 but remained high. Moreover, we demonstrate that most maternal deaths had at least one delay, mostly Delay 1. To prevent maternal deaths caused by Delay 1, the family planning should be promoted to prevent unplanned pregnancies. Educational training for healthcare providers who deliver antenatal care should be strengthened. Furthermore, education on the danger signs of pregnancy and during childbirth should be provided not only to pregnant women and their husbands in communities at health facilities.

    BACKGROUND: In developing countries, it is difficult to collect the data of the underlying cause of death (UCOD), especially when a death does not occur in a health facility. This study aimed to develop a short version of verbal autopsy (VA) and identify the UCOD of adults in Lao People's Democratic Republic (Lao PDR). METHODS: A short version of VA for deaths outside health facilities was developed. This study included all deaths of people aged 15 years old or older in Xaiyabouli Province in 2020. Socio-demographic factors, place of death, and UCOD of the deceased were collected from health facilities or from family members using a questionnaire including the short VA form. UCOD was compared between home deaths and hospital deaths, between the age group of 15-59 years old and the age group ≥ 60 years old, and between males and females. RESULTS: Of all the 1,235 deaths included in this study, 1,012 deaths (81.9%) occured at home and 223 deaths (18.1%) at hospitals. The most common UCOD was senility (13.3%), followed by heart/renal failure (10.5%), pneumonia (9.6%) and traffic accident (7.1%). Compared to hospital deaths, home deaths had more people who were females, 75 years old or older, and Lao-Tai. Home deaths had more deaths than hospital deaths due to accident/injury (16.0% vs. 8.1%), tumor (4.7% vs. 1.8%), and senility (16.2% vs. 0%); fewer deaths due to heart/renal disease (15.1% vs. 32.3%), respiratory disease (12.2% vs. 18.8%), liver/gastro-intestine disease (5.3% vs. 9.0%), and infection (3.1% vs. 14.3%). The age group of 15-59 years had more deaths in the categories of accident/injury (28.1% vs. 4.4%), liver/gastro-intestine disease (8.1% vs. 4.4%), infection (7.2% vs. 3.5%), and tumor (6.0% vs. 2.8%). Males had more deaths due to tumor (5.2% vs. 3.0%) and fewer natural deaths (11.2% vs. 15.9%) than females. CONCLUSIONS: The major UCOD category was heart/renal disease in the adult generation in Xaiyabouli Province. Cost-effective interventions based on the multisectoral noncommunicable disease prevention plan should be appropriately implemented. Mortality surveillance using the short VA tool should be conducted for all home deaths in Lao PDR.

    The system to collect information on mortality statistics in Lao PDR is not well established, accurate and timely death information is therefore not available. This article reports the system and process to make the mortality statistical data of Lao PDR. The country has a paper-based resident registration system, using a death notification document, a death certificate, and a family census book. The death notification document is important as it provides the cause of death, which is issued from a health facility and the village office. In the event of a death occurring at home, the family representative needs to report to the village office verbally to obtain a death notification document. On the other hand, if the death occurred in a medical facility, a death notification document from a health facility is provided. The family representative should bring the death notification document to the district Home Affairs office to register the death and obtain a death certificate. After that, the family representative needs to bring the death certificate to the district Public Security office for an amendment in the family census book. ICD-10 is under development regarding death notification from health facilities under the Ministry of Health. However, it is unclear how death notification from village offices can adopt ICD-10 as the majority of deaths occur outside health facilities. A comprehensive and integrated mortality reporting system is necessary in order to create a holistic health policy and welfare for the country.

    BACKGROUND: In many middle-income countries, cancer incidence and mortality are rapidly increasing, but data for developing a strategy of cancer control are rarely collected or analyzed. This study aimed to identify factors associated with positive cancer screening for the uterine cervix and breast in Jakarta Province, Indonesia. METHODS: The data of 79,660 women who had visual inspection with acetic acid (VIA) and 83,043 women who had clinical breast examination (CBE) in the Jakarta Women Cancer Screening program in 2019 were included in this study. Socio-demographic factors, reproductive factors, lifestyle factors, family history, and the results of VIA and CBE were used for analyses. Binary and multivariate logistic regression analyses were performed to identify factors associated with VIA positive or CBE positive. RESULTS: The positive rate was 0.9% for both VIA and CBE among the screening participants. Factors associated with VIA positive were age < 30 years old, age at menarche ≤ 11 years old, remarriage, lower educational level, having an occupation, partner's occupation other than being an employee, alcohol consumption, smoker, inadequate physical activity, cancer family history, and no Pap smear history. Factors associated with CBE positive were age at menarche ≤ 11 years old, widowed, high education, having an occupation, no breastfeeding history, birth control history, alcohol consumption, smoker, inadequate physical activity, cancer family history, and breast tumor history. CONCLUSION: Factors associated with VIA positive and CBE positive among Indonesian women were revealed. To promote female cancer prevention in Indonesia, the prevalence of screenings should be increased and education about the risk factors should be provided to medical professionals.

    OBJECTIVE: This study aims to estimate the population-based incidence of gestational trophoblastic diseases (GTDs) and to identify the characteristics of gestational trophoblastic neoplasia (GTN) in Japan. METHODS: The annual number of GTD and live births from 1974 to 2018 were used to estimate the incidence of GTD. The data of 1,574 GTN cases from 1999 to 2018 were analyzed to identify the characteristics of low-risk GTN, high-risk GTN, placental site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT). RESULTS: The incidence of hydatidiform mole was 2.02 per 1,000 live births on average which decreased from 1974 to 2008 and increased from 2009 to 2018. The incidence of low-risk GTN, high-risk GTN, PSTT, and ETT was 15.3, 3.5, 0.3, and 0.07 per 100,000 live births, respectively. The estimated incidence of post-molar GTN was 9.8% of molar patients. High-risk GTN was diagnosed more pathologically, had more various kinds of antecedent pregnancies, and had longer intervals after the antecedent pregnancy compared to low-risk GTN. Furthermore, 8.2% of high-risk GTN occurred after the subsequent non-molar pregnancy of hydatidiform mole. The cumulative percentage of developing high-risk GTN after hydatidiform mole reached 89.3% at the 60th month. CONCLUSION: The incidence of hydatidiform mole, low-risk GTN, high-risk GTN was 2.02 per 1,000 live births, 15.3 per 100,000 live births, and 3.5 per 100,000 live births, respectively. High-risk GTN was diagnosed more pathologically and later after the antecedent pregnancy than low-risk GTN. Following molar patients for five years is needed to improve the mortality of malignant GTN.

    The Center for Child and Adolescent Mental Health (CCAMH) is one of the centers that have psychiatric specialists for children in Cambodia. This study aims to understand the characteristics of children with neuro-developmental disorders, especially autism spectrum disorder (ASD), at CCAMH. This study included 440 cases that were randomly chosen from 2,147 new patients at CCAMH in 2018-2019 and were aged 0-12 years. Socio-demographic factors, parent's information, obstetrical factors, and clinical data were collected from patients' records. A logistic regression analysis and Pearson's chi-square test were used to compare the characteristics between children who were finally diagnosed with ASD and the others (non-ASD). Of the 440 patients, most were male (75.2%), 0-4 years old (57.7%), and diagnosed with ASD (50.0%). Common symptoms were delay of speech, playing alone, and hyperactivity. ASD was significantly more prevalent in male patients compared to females and in the 0-4 years age group compared to the 5-12 years age group. Parents who lived in Phnom Penh and had high education were more likely to visit the CCAMH with their children who were diagnosed with ASD. Regarding treatment, approximately half of all 440 patients had family counselling and psychosocial education. ASD patients had more speech therapy, special education and structured teaching, and networking and coordination therapy compared to non-ASD patients. To provide education and therapy to children with ASD and their parents from the early stage, information about the center and ASD should be widely distributed to all parents in Cambodia.

    BACKGROUND: The concept of customer satisfaction is gaining hold in all corporate sectors worldwide, and a satisfaction survey is used as a tool to discover service problems and as a chance for customers to rate their experience with health care services. A high degree of patient satisfaction with the services given has been found in numerous studies conducted in Malaysian public health care facilities. However, there is limited information available on caregiver satisfaction with pediatric clinics run by the Ministry of Health (MoH) of Malaysia. OBJECTIVE: This was the first research performed at a public hospital's pediatric clinic, which was the first hospital to adopt the public-private-partnership model under the MoH, with the aim of discovering the prevalence and factors affecting the satisfaction of caregivers at the national referral center. METHODS: Cross-sectional research using the standard self-administered SERVQUAL questionnaire was conducted among caregivers accompanying their children to the clinic. The questionnaire consists of 16 paired statements to evaluate their expectations and experiences with the clinic services. RESULTS: A total of 459 caregivers were involved in this study with a majority aged between 30 and 39 years (n=254, 55.4%). Caregivers from the Indian community (adjusted odds ratio [AOR] 2.91, 95% CI 1.37-6.18) and lower income groups (AOR 2.94, 95% CI 1.87-4.64), and those with lower educational backgrounds (AOR 3.58, 95% CI 1.19-10.72) were more likely to be satisfied with the quality of pediatric clinic services. Housewives/househusbands (AOR 0.48, 95% CI 0.25-0.90), on the other hand, appeared less likely to be satisfied with the services provided during their visit to the clinic. Looking at overall patient satisfaction, 50.5% (n=232) of caregivers demonstrated satisfaction with the quality of services, compared to 49.5% (n=227) of dissatisfied respondents. CONCLUSIONS: This paper suggests that, although most caregivers are satisfied with the services, greater emphasis must be placed on delivering reliable service in response to the MoH's mission to provide quality and integrated people-centered health services in Malaysia.

    As the aging population grows worldwide, the problem of age-related health is becoming an important public health concern. Dementia is a devastating disease that places a significant physical, emotional, and financial burden on patients, their caregivers, and society. It is predicted to increase in developing countries. The Revised Hasegawa's Dementia Scale (HDS-R) has been used in many Asian countries to measure cognitive function. However, there is still no Vietnamese version of the HDS-R. Therefore, this paper describes the development of the HDS-R scale and manual in Vietnamese language. Two Vietnamese researchers translated the HDS-R from English to Vietnamese. To confirm the accuracy of the translation, two other Vietnamese researchers conducted a back-translation. Another pair of Vietnamese researchers compared the back-translated English version to the original one. All six researchers discussed the inconsistencies between English HDS-R scale and manual and derived the most suitable version for the Vietnamese context. In Questions 4 and Question 7, we changed the words from "cherry blossom" and "train" to "daisy flower" and "bicycle" for the first option, and from "plum blossom" to "rose" for the second option. We also changed the expressions in some places in the manual to fit the Vietnamese language. Future studies are needed to validate this version to be able to access cognitive function in both clinical and public healthcare settings.

    In Lao PDR, Ministry of Health introduced District Health Information Software 2 (DHIS2) in 2013. Although DHIS2 includes cause of death, Lao government did not request to report cause of death through DHIS2, resulting in no information on frequency of underlying cause of death even for the deaths at medical facility. This study aimed to collect the information on the underlying cause of death at all medical facilities in Xaiyabouli province, a rural area in Lao PDR. As well as the point estimate of the proportion, a 95% confidence interval (CI) based on a binomial distribution was calculated for each cause of death. According to the local government request, 226 deaths (128 males and 98 females) in 2019 were reported from all medical facilities in the province. Among them, infectious diseases were the most frequent (33.6%, 95% CI 27.5-40.2%); sepsis (16.8%, 95% CI 12.2-22.3%), pneumonia (8.8%, 95% CI 5.5-13.3%), and meningitis (4.9%, 95% CI 2.5-8.5%). Heart diseases were 15.9% (95% CI 11.4-21.4%) including heart failure and myocardial infarction. Injury was 10.2% (95% CI 6.2-14.4%) including brain injury. Neonatal death was 10.6% (95% CI 6.9-15.4%). Among those, preterm death was common (8.8%, 95% CI 5.3-13.3%). Renal failure was 8.0% (95% CI 4.8-12.3%). According to civil registration covering all deaths both at facilities and outside facilities, deaths at facilities were 16.8% of the whole deaths (1,372 deaths) in Xaiyabouli province. Although deaths outside facilities were not included, this is the first report demonstrating cause of death in one province in Lao PDR.

    INTRODUCTION: This study aimed to examine the reporting rate and the factors associated with serious outcomes of patient safety incidents at public hospitals in Malaysia. METHODS: All patient safety incidents reported in the e-Incident-Reporting System from January to December 2019 were included in the study. A descriptive study was used to describe the characteristics of incidents, and logistic models were used to identify factors associated with low reporting rates and severe harm or death outcomes of incidents. RESULTS: There were 9431 patient safety incidents reported in the system in 2019. The mean reporting rate was 2.1/1000 patient bed-days or 1.5% of hospital admissions. The major category of incidents was drug-related incidents (32.4%). No-harm incidents contributed to 56.1% of all the incidents, while 1.1% resulted in death. More hospitals in the eastern (odds ratio [OR], 12.1) and southern regions (OR, 6.1) had low reporting rates compared to the central region. Incidents with severe harm or death outcomes were associated with more males (OR, 1.4) than females and with the emergency department (OR, 10.6), internal medicine (OR, 5.7), obstetrics and gynecology (OR, 2.4), and surgical department (OR, 5.0) more than the pharmacy department. Compared to drug-related incidents, operation-related (OR, 3.0), procedure-related (OR, 3.5), and therapeutic-related (OR, 4.8) incidents had significantly more severe harm or death outcomes, and patient falls (OR, 0.4) had less severe harm or death outcomes. CONCLUSION: The mean reporting rate was 2.1/1000 patient bed-days or 1.5% of hospital admissions. More hospitals in the eastern and southern regions had low reporting rates. Certain categories of incidents had significantly more severe outcomes.

    Although diagnosis and treatment of tuberculosis (TB) have been improved in many countries, delays in the diagnosis and treatment remain problematic in resource-limited countries. This study aimed to identify factors affecting delays in TB care in Mongolia. Data on TB cases registered from January 2016 to December 2017 were obtained from the national registry of TB at the Department of TB Surveillance and Research in National Center for Communicable Disease. The total number of TB cases registered in these two years was 8,166, including 3,267 cases of newly diagnosed pulmonary TB. Pulmonary TB cases (1,836 males and 1,431 females) were analyzed to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Patient delays longer than the median (28 days) were significantly associated with patient age >32 years (aOR=1.31, 95%CI: 1.14-1.51), residence in areas other than Ulaanbaatar (aimags) (aOR=1.38, 95%CI: 1.20-1.59), and smear-negative (aOR=0.57, 95%CI: 0.47-0.69). Health system delays longer than the median (7 days) were significantly associated with patient age >32 years (aOR=1.16, 95%CI: 1.00-1.33), residence in aimags (aOR=0.82, 95%CI: 0.71-0.95), special facilities including a prison hospital (aOR=4.40, 95%CI: 2.42-7.83), registration in 2017 relative to 2016 (aOR=0.83, 95%CI: 0.71-0.95), and smear-negative (aOR=1.72, 95%CI: 1.42-2.07). Total delays longer than the median (45 days) were significantly associated with patient age >32 years (aOR=1.39, 95%CI: 1.21-1.60), residence in aimags (aOR=1.27, 95%CI: 1.11-1.47), and smear-negative (aOR=0.74, 95%CI: 0.62-0.90). To shorten the total delay, improvement of the access to medical facilities in aimags is necessary.

    INTRODUCTION: Lysosome-associated membrane glycoprotein 2 (LAMP-2) is a target protein for glycosylation by N-acetylglucosaminyltransferase IV (GnT-IV), which catalyzes the formation of β1,4GlcNAc branches on the mannose core of N-glycans in choriocarcinoma cells. However, the role of LAMP-2, especially when it is expressed in the cell surface membrane of choriocarcinoma cells, has not been well investigated in the progression of choriocarcinoma. This study aimed to elucidate the function of the cell surface membrane LAMP-2 in the malignancy of choriocarcinoma. METHODS: We evaluated the localization of LAMP-2 in some choriocarcinoma cell lines and clinical samples of choriocarcinoma, normal placenta, hydatidiform mole, and invasive mole by flow cytometry, immunocytochemistry, and immunohistochemistry. We performed functional experiments using the knockout or overexpression model of LAMP-2 in the presence or absence of galectins. RESULTS: LAMP-2 was observed in the cell surface membrane of some choriocarcinoma cell lines and tumor cells of choriocarcinoma tissue and trophoblasts of the placenta, hydatidiform mole, and invasive mole. Cell surface membrane LAMP-2 knockout decreased cell adhesion and invasion in choriocarcinoma cells. Conversely, cell surface membrane LAMP-2A overexpression increased cell adhesion and invasion. Experiments in the presence of galectins revealed that abundant N-glycans bound to the peptide core of the luminal side of the cell surface membrane LAMP-2 mediated cell adhesion of choriocarcinoma cells by interacting with galectins in the extracellular matrix (ECM). DISCUSSION: Cell surface membrane LAMP-2, which is glycosylated by GnT-IV, contributes to the malignancy of choriocarcinoma by promoting cell adhesion with the ECM via abundant N-glycans.

    This study aimed to describe the socio-demographic and clinical characteristics of dengue inpatients at a provincial hospital, and to identify factors associated with severe dengue. This is a retrospective study involving 402 dengue patients admitted to the Savannakhet Provincial Hospital, Lao People's Democratic Republic (Lao PDR), between January 2018 and April 2019. Socio-demographic factors, clinical signs and laboratory data on admission, final diagnosis, use of health care services before admission, admission date, and hospitalization period were collected from patient records. The number of dengue inpatients was higher in the rainy season than in the dry season. Of the 402 patients, 205 patients (51.0%) were finally diagnosed with severe dengue. Children aged <15 years had more symptoms, higher proportion of severe dengue (69.8% vs. 35.9%), and longer hospitalization (3.5 days vs. 3.0 days) than adults aged ≥15 years. In multivariable analyses, factors associated with severe dengue were nausea on admission (adjusted odds ratio=3.57, 95% CI=1.05-12.09, P=0.04) in children and persistent vomiting on admission (adjusted odds ratio=3.82, 95% CI=1.23-11.92, P=0.02) in adults. In adults, the creatinine level on admission was significantly higher in patients with a final diagnosis of severe dengue compared to the others. The proportion of severe dengue in our study was higher than that in other countries. Nausea and persistent vomiting on admission were suggested to be predictive factors for severe dengue. To reduce the incidence of severe dengue in Lao PDR, improvements in access to health care, referral system, and training of health care workers are needed.

    AIM: Management of hydatidiform mole is important to reduce the mortality and morbidity of choriocarcinoma. This study aims to understand the existing health services for hydatidiform mole and to estimate the incidence of gestational trophoblastic disease (GTD) in Cambodia. METHODS: A questionnaire was used to collect information on the existing health services for pregnancy and hydatidiform mole at health facilities from attendants of the 16th Annual Conference of the Cambodian Society of Gynecology and Obstetrics in 2017. The incidence of GTD in 2014-2017 was estimated using Health Information System data. RESULTS: A total of 126 attendants, who were from all provinces except three provinces, answered the questionnaire. The work places were national hospitals (n = 29), provincial hospitals (n = 42), district hospitals (n = 20), health centers (n = 6), and others (n = 29). The answers of participants from the public sector suggested the following: Ultrasonography is available at all hospitals but not health centers; Human chorionic gonadotropin (hCG) measurement is only available at national hospitals; Treatment of hydatidiform mole is performed at national hospitals and provincial hospitals; and Treatment of gestational trophoblastic neoplasia (GTN) is provided at national hospitals. The incidence of hydatidiform mole and GTN at health facilities in the public sector in 2014-2017 was 0.95 per 1000 deliveries and 6.58 per 100 000 deliveries, respectively. CONCLUSIONS: The results suggest that provincial hospitals are important to detect suspected invasive mole and refer to national hospitals for diagnosis and treatment. Further studies on the management of GTD and development of the guidelines of GTD are needed.

    INTRODUCTION: Gestational trophoblastic neoplasia (GTN) include a group of malignant neoplasms that originate from the trophoblasts of placental tissue in molar or nonmolar pregnancy. Currently, it is unclear whether the prognosis of high-risk GTN or gestational choriocarcinoma succeeding molar pregnancy or that following a nonmolar one is better. Comparison of the genetic short tandem repeat (STR) patterns of the DNA extracted from the tumor, patient, and her partner allows the genetic origins of the choriocarcinoma to be distinguished - whether it is gestational or non-gestational and whether it is derived from a molar or nonmolar pregnancy in the event it is gestational. This study aimed to investigate the causative pregnancy of patients with high-risk GTN, especially those with poor outcomes, and assess the impact of the causative pregnancy on patient outcome. METHODS: We evaluated 24 patients who were diagnosed with high-risk GTN between January 2000 and October 2019, including 15 cases of pathologically proven gestational choriocarcinomas and the causative pregnancy was investigated by STR analysis in which tumor DNA could be extracted. RESULTS: In high-risk GTN without history of anteceding molar pregnancies, nonmolar pregnancy was the causative pregnancy, which was confirmed in three cases. Molar pregnancy appeared be the causative pregnancy of high-risk GTN in patients with a history of antecedent molar pregnancies either with or without interruption by subsequent nonmolar pregnancies prior to developing high-risk GTN. High-risk GTN in most of the evaluated deceased cases (three of four) was due to nonmolar pregnancy, while all but one case with molar pregnancy as the causative pregnancy survived. DISCUSSION: STR analysis can distinguish the causative pregnancy of high-risk GTN, and nonmolar pregnancy as the causative pregnancy might have negative effects on the outcome of the disease.

    Hyperglycosylated human chorionic gonadotropin (H-hCG) is secreted from choriocarcinoma and contains a core2 O-glycan formed by core2 β1,6-N-acetylglucosaminyl transferase (C2GnT). Choriocarcinoma is considered immunogenic as it is gestational and contains paternal chromosomal components. Here we examined the function of C2GnT in the evasion of choriocarcinoma cells from natural killer (NK) cell-mediating killing. We determined that C2GnT is highly expressed in malignant gestational trophoblastic neoplasms. C2GnT KO downregulates core2 O-glycan expression in choriocarcinoma cells, which are more efficiently killed by NK cells than control cells. C2GnT KO cell containing tumor necrosis factor-related apoptosis inducing ligand have lower viability than control cells. Additionally, poly-N-acetyllactosamine in core2 branched oligosaccharides on MHC class I-related chain A (MICA) and mucin1 (MUC1) is significantly reduced in C2GnT KO cells. Meanwhile, the cumulative survival rate of nude mice inoculated with C2GnT KO tumors was higher than that of the control group. These findings suggest that choriocarcinoma cells may escape NK cell-mediated killing via glycosylation of MICA and MUC1.

    Gestational choriocarcinoma is a gestational trophoblastic neoplasia (GTN) originating from trophoblastic cells with abnormal proliferation. Although chemotherapy is effective for treating this cancer, when patients develop chemoresistance, personalized treatment, such as the use of drugs matching their genomes, is required. The present report describes a case of intractable gestational choriocarcinoma identified using a next-generation sequencing (NGS)-based tumor panel. A 51-year-old woman was diagnosed with gestational choriocarcinoma via pathological and short tandem repeat analyses. The patient did not achieve remission despite many regimens of chemotherapy, including high-dose therapy with autologous peripheral blood stem cell transplantation. To identify drugs tailored to this particular choriocarcinoma, NGS was performed on the tumor of the patient, and the tumor genome was compared with that of the patient's blood sample using the NCC Oncopanel System. Consequently, 245 single nucleotide variants (SNVs) with a mean SNV allele frequency of 63.1% were identified. This high frequency was because the genome of the gestational choriocarcinoma contained part of the genome of the partner. Therefore, our experience of the present intractable case of choriocarcinoma suggested that matched normal-tumor pair analysis is not appropriate for treatment decisions in GTN cases. When using an NGS-based tumor panel to assess choriocarcinoma, researchers must consider whether the genomic DNA of the patient and their partner are involved in the GTN.

    The aim of this study is to determine whether the myocardial performance index (MPI) is increased in fetal growth restriction (FGR) fetuses and if increased MPI is related to adverse outcomes of FGR. This is a prospective cross-sectional study. Seventy-three late-onset FGR fetuses and 97 gestational-age matched control fetuses were enrolled in this study. Fetal blood flow parameters including MPI values were measured and compared between the two groups. For the effect of severity of growth restriction on MPI value, they were also compared with < 3rd and 3rd - 10th centile groups. FGR fetuses were divided into two groups by favorable and adverse outcome and ultrasound parameters were compared between these two groups. Moreover, significant factors related to adverse outcomes by univariate analysis were analyzed by multivariate logistic regression analysis. Pulsatility index of umbilical arterial flow (UA-PI), MPI and amniotic fluid index in the FGR were significantly different from the control fetuses. However, no significant difference between < 3rd and 3rd - 10th centile groups was detected in MPI and UA-PI. The increased levels of MPI and UA-PI were independently related with adverse outcome of late-onset FGR pregnancy. In conclusion, MPI values were increased in late-onset FGR pregnancy, and the higher level of MPI could predict adverse outcome as well as the measurement of UA-PI. Clinicians should consider cardiac dysfunction in FGR through increased MPI.

    BACKGROUND: Pure ovarian choriocarcinoma can be gestational or nongestational in origin. Nongestational pure ovarian choriocarcinoma is extremely rare and the prognosis is thought to be worse than that of the gestational type in patients with metastatic disease. We present a case of metastatic pure ovarian choriocarcinoma with poor prognosis in which the origin was identified as nongestational by DNA short tandem repeat (STR) analysis. CASE PRESENTATION: A nulliparous woman in her thirties with metastatic choriocarcinoma was referred to our hospital after initial treatment proved unsuccessful. Two months earlier, she had undergone brain tumor resection and histological examination confirmed choriocarcinoma. Serum human chorionic gonadotropin (hCG) concentration at initial diagnosis was 5030 IU/L. Two cycles of a combination chemotherapy regimen of methotrexate, etoposide, and actinomycin-D (MEA therapy), which is commonly used for gestational choriocarcinoma, was administered. However, the disease could not be controlled. Imaging modalities at presentation revealed tumor present in the left ovary and left lung, but not in the uterus, which led us think that the choriocarcinoma was nongestational. Bleomycin, etoposide, and cisplatin (BEP therapy) which is commonly used for nongestational choriocarcinoma (malignant germ cell tumor) and surgical resection of the uterus, bilateral ovaries, and an affected part of the left lung led to the nadir level of hCG, but the tumor relapsed and levels of hCG again increased. To investigate the origin of choriocarcinoma, we performed DNA STR analysis of tumor cells and oral mucosal cells. Analysis revealed the origin of the choriocarcinoma as nongestational, as the genotype of tumor cells entirely corresponded with that of oral mucosal cells. BEP therapy and chemotherapy regimens administered for nongestational choriocarcinoma and gestational choriocarcinoma proved ineffective, and the patient died 21 months after diagnosis of metastatic choriocarcinoma. CONCLUSION: Metastaic nongestational pure choriocarcinoma of ovary is an extremely rare and an aggressive disease, frequently resulting in poor outcome.

    This study aimed to identify hospital neonatal mortality rate (NMR) and the causes of neonatal deaths, and to understand risk factors associated with neonatal mortality in a national tertiary hospital in Cambodia. The study included all newborn infants, aged 0-28 days old, hospitalized in the Pediatrics department of Khmer-Soviet Friendship Hospital between January 2016 and December 2017. In total, 925 infants were included in the study. The mean gestational age was 35.9 weeks (range, 24-42 weeks). Preterm infants and low birth weight accounted for 47.5% and 56.7%, respectively. With respect to payment methods, the government (53.5%) and non-governmental organizations (NGO) (13.7%) paid the fees as the families were not in a financial position to do so. The hospital NMR at the Pediatrics department was 9.3%. Respiratory distress syndrome (37.2%) was the main cause of deaths followed by hypoxic-ischemic encephalopathy (31.4%) and neonatal infection (21.0%). Factors associated with neonatal mortality were Apgar score at 5th minute <7 (adjusted odds ratio (AOR) = 3.57), payment by the government or NGO (AOR = 11.32), admission due to respiratory distress (AOR = 11.94), and hypothermia on admission (AOR = 9.41). The hospital NMR in the Pediatrics department was 9.3% (95% confidence interval 7.50-11.35) at Khmer-Soviet Friendship Hospital; prematurity and respiratory distress syndrome were the major causes of neonatal mortality. Introducing continuous positive airway pressure machine for respiratory distress syndrome and creating neonatal resuscitation guidelines and preventing hypothermia in delivery rooms are required to reduce the high NMR.

    BACKGROUND: In the context of an aging population, quality of life (QOL) is an important consideration for the well-being of the elderly. However, there is limited information on the QOL of the elderly in Myanmar. This study aimed to explore the risk factors for low QOL among the elderly in urban and peri-urban areas of the Yangon Region, Myanmar. METHODS: A community-based, cross-sectional study was conducted among the elderly aged 60 years or older in two urban and two peri-urban townships in the Yangon Region from July to September 2019. A multi-stage sampling method was used to recruit study participants using a pre-tested questionnaire. A total of 616 (305 males and 311 females) elderly people were interviewed using a face-to-face interview technique. Multiple linear regression analysis was performed on the four domains (physical health, psychological health, social relationship, and environment) of QOL measured with the WHOQOL-BREF. RESULTS: Income level and having intimate friends influenced the QOL scores of the elderly in all domains, while education level and marital status influenced psychological health, social relationship, and environment domains. Social interaction with neighbors increased the QOL scores for physical health, social relationship, and environment domains. Living in peri-urban areas was associated with lower QOL scores for physical health, psychological health, and environment, while participation in group activities increased QOL scores in these domains. Having comorbidities affected the QOL for psychological health and environment domains, while the frequency of going out affected physical health, and the frequency of religious performance affected social relationship. CONCLUSION: Residential location, education level, marital status, income, comorbidities, social interactions with neighbors and friends, participation in group activities, and frequencies of going out and religious activities should be considered in planning and implementing programs for the elderly in Myanmar. Peri-urban development, strengthening healthcare and social security systems, and encouraging social interaction and participation in group activities play critical roles in improving the QOL for elderly residing in Myanmar.

    BACKGROUND: Diagnosis by computed tomography (CT) and magnetic resonance imaging (MRI) is important for patient care. However, the geographic distribution and utilisation of these machines in countries with limited resources, such as Myanmar, have not been sufficiently studied. Therefore, this study aims to identify the geographic distribution and utilisation of CT and MRI services at public hospitals in Myanmar. METHODS: This nationwide, cross-sectional study was conducted at 43 public hospitals in Myanmar. Data were collected retrospectively using a prepared form from 1st January 2015 to 31st December 2017 at public hospitals in Myanmar. A descriptive analysis was performed to calculate the number of CT and MRI units per million population in each state and region of Myanmar. The distribution of CT and MRI units was assessed using the Lorenz curve and Gini coefficient, which are indicators of inequality in distribution. RESULTS: In total, 45 CT and 14 MRI units had been installed in public hospitals in Myanmar by 2017. In total, 205,570 CT examinations and 18,981 MRI examinations have been performed within the study period. CT units per million population in 2017 varied from 0.30 in Rakhine State to 3.22 in Kayah State. However, MRI units were available only in public hospitals in five states/regions. The Gini coefficient for CT and MRI was 0.35 and 0.69, respectively. An upward trend in the utilisation rate of CT and MRI was also observed during the study period, especially among patients aged between 36 and 65 years. CONCLUSIONS: Throughout Myanmar, CT units were more equally distributed than MRI units. CT and MRI units were mostly concentrated in the Yangon and Mandalay Regions, where the population density is higher. The geographic distribution and utilisation rate of CT and MRI units varied among states, regions, and patients' age group. However, the utilisation rates of CT and MRI increased annually in all states and regions during the review period. The Ministry of Health and Sports in Myanmar should consider the utilisation and population coverage of CT and MRI as an important factor when there will be procurement of those medical equipment in the future.

    Diarrhea is the second leading cause of under-five mortality and globally accounts for 526,000 child deaths every year. Afghanistan, with 33,000 child deaths in 2012, was ranked 8th among nations, with the highest under-five deaths being from pneumonia and diarrhea. This study aimed to identify the determinants of diarrhea in children under the age of five in Afghanistan. A secondary data analysis of the Afghanistan Demographic and Health Survey (AfDHS) 2015 was focused on diarrhea in children under the age of five. The dataset of the AfDHS 2015 was used for the analysis. The subjects for this study were 30,238 under-five children. A logistic regression model was applied to examine the determinants of childhood diarrhea. This study found that 7,921 (26.2%) out of 30,238 under-five children had diarrhea within the two weeks preceding the survey. Higher maternal education accompanied a lower risk of childhood diarrhea with an adjusted odds ratio (AOR) of 0.70 (P<0.01) than did no education. Flush toilets (AOR=0.84, P<0.01) and traditional dry vaults (AOR=0.83, P<0.001) were less likely associated with diarrhea compared with pit latrines. Tube wells, public taps, and unprotected wells and springs were sources of drinking water with a higher risk of diarrhea than piped water. This study identified that the type of toilet facility, source of drinking water, age of the child, and maternal education were important determinants of under-five diarrhea. Intervention programs concerning improved sanitation facilities, sources of drinking water, and raising women's level of education and health awareness are important.

    Mongolia had an epidemic of measles in 2015-2016, even though more than 90% of the population have been vaccinated since 1997. This study aimed to examine the associations between unvaccinated proportion and measles incidence according to aimag. Mongolia has 21 provinces (aimag) with Ulaanbaatar as the capital city. Vaccination coverage between 1991 and 2014 and measles incidence according to aimag were obtained from the National Center for Communicable Diseases of Mongolia database. Accumulated unvaccinated proportion (AUP) among those aged 1 to 24 years in 2015 was estimated from the unvaccinated at the 1st dose of 1991 to 2014. From 1991 to 2014, unvaccinated proportion among those aged 1 to 24 years in the whole country has been reducing from 28.0% in 1991 to 1.8% in 2014. The AUP in 2015 varied from 2.7% (Selenge) to 21.8% (Govisumber). The incidence was remarkably higher in only two aimags with a large density of the unvaccinated aged 1 to 24 years (Ulaanbaatar and Darkhan-Uul) than in the other aimags. The incidence had no significant correlation with the AUP, although the correlation between the incidence and the density of unvaccinated aged 1 to 24 years was significant when the two aimags were included. In conclusion, the AUP between 2.7% and 21.8% had no correlation with the incidence according to aimags in Mongolia measles epidemic 2015-2016.

    This study aims to identify the pathogens of diarrhea in Vientiane Capital, Lao People's Democratic Republic (Lao PDR). The data of 2482 patients who visited eight health facilities due to diarrhea in 2012-2015 were retrospectively reviewed. Stool or rectal swabs collected from all patients were tested for bacteria. Children who were under 5 years old were additionally tested for rotavirus. Of 2482 cases, 1566 cases were under 5 years old, and at least one enteropathogen was detected in 475 cases (19.1%). Salmonella species was the most commonly detected bacterial pathogen. Enteropathogenic Escherichia coli (EPEC) and Salmonella species was the major pathogen in the dry season and the wet season, respectively. Eighty-seven patients tested positive for multiple bacteria. Rotavirus was detected in 291 children under 5 years old (32.4%), mostly from October to April. The major bacteria of coinfection with rotavirus were EPEC followed by Salmonella species. Salmonella species was the predominant bacterial pathogen of diarrhea of all ages, and rotavirus was the predominant pathogen among children under 5 years old. Further studies examining other types of pathogens for diarrhea and the introduction of a rotavirus vaccine for children are needed in Lao PDR.

    OBJECTIVE: The aim of this study was to evaluate routine second curettage for hydatidiform mole (HM) by comparing the characteristics and outcomes of developing gestational trophoblastic neoplasia (GTN). STUDY DESIGN: This was a cohort study including 173 patients diagnosed with HM between January 2002 and August 2019 who were followed up at Nagoya University Hospital, Japan. After an evacuation, 105 and 68 patients were managed with the routine method (routine group) and elective method (elective group) for a second curettage, respectively. The routine second curettage was performed around 7 days after the first evacuation. Patients in the elective group underwent a second curettage if there was ultrasonographic evidence of molar remnants in the uterine cavity. Socio-clinical factors were retrospectively compared between the routine and elective groups, and between patients showing regression and those who developed GTN. RESULTS: The incidence of GTN was 15.2% in the routine group and 20.6% in the elective group, and the difference was not significant (P = 0.364). The median GTN risk score was significantly higher in the routine group than in the elective group (P = 0.033). Presence of a complete HM, gestational age, and a pre-treatment human chorionic gonadotropin level of ≥ 200,000 mIU/mL were independent risk factors for GTN in molar patients. CONCLUSION: The incidence of GTN was unchanged but the risk score of GTN was higher in the routine group than in the elective group. Routine second curettage may not be necessary, but further study will be needed to confirm this.

    BACKGROUND: Globally, alcohol consumption is a significant public health concern and it is one of the most important risk behaviours among university students. Alcohol consumption can lead to poor academic performance, injuries, fights, use of other substances, and risky sexual behaviours among students. However, the study explored the prevalence of alcohol consumption and the associated risk factors among university students since these have not been fully examined in previous research. Therefore, the aim of this study was to explore the prevalence of alcohol consumption and the associated risk factors among university students in Myanmar. METHODS: The present cross-sectional study was conducted using a sample of 15-24-year-old university students who were selected from six universities in Mandalay, Myanmar, in August 2018. In total, 3,456 students (males: 1,301 and females: 2,155) were recruited and asked to respond to a self-administered questionnaire. Multiple logistic regression analysis was used to estimate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for alcohol consumption among university students. RESULTS: The prevalence of alcohol consumption in the previous 30 days was 20.3% (males: 36.0%, females: 10.8%). The alcohol consumption was significantly higher among males (AOR = 2.3, 95% CI; 1.9-2.9), truant students (AOR = 2.1, 95% CI; 1.3-3.3), smokers (AOR = 7.0, 95% CI; 5.1-9.7), students who reported feeling of hopelessness or sadness (AOR = 1.4, 95% CI; 1.2-1.8), peers' alcohol consumption (AOR = 7.5, 95% CI; 4.8-11.7). CONCLUSION: The present study revealed that males, smokers, peer alcohol consumption, and truant students had higher odds of alcohol consumption among the students. Therefore, effective campus-based counselling, peer education, and national surveillance systems that can monitor risky drinking behaviours among university students should be implemented. Further, government regulations that control the production, sale, promotion, advertising, and restriction of alcohol should be well developed and strengthened, as in the case of other Southeast Asian countries.

    BACKGROUND: Ready-to-eat (RTE) food consumption has become popular in the working community with the increase in full-time jobs and the limited time to prepare food. Although RTE food is essential for this community, its consumption causes obesity. In Myanmar, obesity is a modifiable risk factor for non-communicable diseases, causing increases in morbidity and mortality. This study aimed to identify the association between body mass index (BMI) and RTE food consumption among sedentary staff in Nay Pyi Taw Union Territory, Myanmar. METHODS: A cross-sectional study was conducted in 2018, in which 400 respondents participated in face-to-face interviews. The study area was selected using simple random sampling and drawing method. Measuring tape and digital weighing scale were used to measure the height and weight of the respondents. BMI was calculated by dividing the weight by height squared (kg/m2). Overweight and obesity were categorized by World Health Organization cut-off points. The collected data were analyzed using multiple logistic regression to estimate the adjusted odds ratio (AOR), and the 95% confidence interval (CI). RESULTS: This study revealed that sedentary staff who consumed RTE food once or more per month were nearly five times more likely to be overweight and obese (AOR = 4.78, 95% CI 1.44-15.85) than those who consumed RTE food less frequently. In addition, five factors namely being older than 32 years (AOR = 3.97, 95% CI 1.82-8.69), preference for RTE food (AOR = 8.93, 95% CI 2.54-31.37), light-intensity of physical exercise (AOR = 3.55, 95% CI 1.63-7.73), sedentary leisure activities (AOR = 3.32, 95% CI 1.22-9.03), and smoking (AOR = 5.62, 95% CI 1.06-29.90) were positively associated with overweight and obesity. CONCLUSION: Frequent consumers of RTE food and less physically active sedentary staff were more likely to be overweight and obese. This study highlights the urgent need to raise awareness regarding healthy lifestyle behaviors among the working community to reduce the burden of obesity-related chronic diseases. Moreover, sedentary workers should be aware of the food-based dietary guidelines of the country. Policy makers should strictly enforce nutritional labeling of RTE food, and strictly prohibit over-branding of RTE food.

    OBJECTIVES: To examine the associations of current tobacco use with tobacco advertising, promotion and sponsorship (TAPS), and illicit tobacco sales exposures among Myanmar high school students. DESIGN: A quantitative, cross-sectional study. SETTING: Seven high schools from both urban and rural areas of four states and regions in Myanmar. PARTICIPANTS: In total, 1174 high school students (482 males and 692 females) were interviewed using a self-administered questionnaire. MAIN OUTCOME MEASURE: Current tobacco use of participants, defined as using any kind of smoked or smokeless tobacco product at least one occasion within the past 30 days. RESULTS: The prevalence of TAPS exposure was 90.9% among high school students in Myanmar. Current tobacco use was positively associated with being over 14 years old (adjusted OR (AOR) 9.81; 95% CI 4.54 to 21.19), being male (AOR 28.06; 95% CI 13.29 to 59.25), exposure to any kind of TAPS (AOR 6.59; 95% CI 2.33 to 18.64), having seen any smoked tobacco product for sale inside or within 100 feet of the school premises (AOR 4.17; 95% CI 1.65 to 10.58), having seen the sale or gifting of any smoked tobacco product to minors (AOR 6.46; 95% CI 2.18 to 19.12) and having seen the sale or distribution of any smoked tobacco product by minors (AOR 2.42; 95% CI 1.42 to 4.10). Having ever received health education about tobacco use (AOR 0.45; 95% CI 0.27 to 0.78), or having a higher perception score of tobacco use (AOR 0.17; 95% CI 0.10 to 0.30) were negatively associated with current tobacco use. CONCLUSIONS: There was an alarming prevalence of TAPS exposure among Myanmar high school students. TAPS exposure and violations of tobacco sale regulations were strong risk factors for current tobacco use among Myanmar high school students, while health education about tobacco products was reported as an effective protective factor. Specific smokeless tobacco sale regulations for minors are needed immediately in Myanmar.

    Health services for pregnancy and delivery at public health facilities are fully subsidized by the government in Mongolia. However, it has been reported that health financing, budget planning, and implementation processes are weak. Therefore, this study aims to estimate the costs per inpatient of vaginal delivery and cesarean section (C-section) by using data gathered from a tertiary hospital in Ulaanbaatar. Inpatient and financial data were collected from the Statistics and Finance, Economics Department of National Center for Maternal and Child Health. A top-down method was used for the calculation of unit costs. The total number of deliveries in 2016 were 11,033, including 7,777 vaginal deliveries and 3,256 C-sections. The cost per inpatient stay for vaginal delivery and C-section were USD 255 and USD 592, respectively. The average cost per bed-day of the six departments of the obstetrics and gynecology hospital was USD 80. The percentage that represents employees' salary in the cost per inpatient was as low as 12.4% for vaginal delivery and 18.5% for C-section, although the cost for salaries accounted for 51.2% of the total expenditure of the hospital. Results show that the cost per inpatient of C-section was two times higher than that of vaginal delivery. The cost of childbirths may account for approximately 9% of total health expenditure of the country. These results may be advantageous to the government in instituting a policy and controlling the health care budget to improve cost-effectiveness and equal access to all in health care services in Mongolia.

    In Lao People's Democratic Republic (Lao PDR), reports on disease frequency are very limited. This study aimed to report frequencies of the main cause of admission among inpatients of a tertiary general hospital (Mittaphab Hospital) in Vientiane. Subjects were inpatients who were admitted from January 3 to February 2 in 2017. The dataset were made as a pilot run to establish hospital statistics. The data on sex, age, address (province), dates of admission and discharge, and main diagnosis were collected from paper-based medical charts. International Classification of Diseases 10 was applied for classifying the main diagnosis. During the 1-month period, 1,201 inpatients (637 males and 564 females) were admitted, including 171 (14.2%) aged <20 years and 254 (21.1%) aged ≥60 years. About 20% patients were from outside of Vientiane. Among them, 67.5% (62.5% in males and 73.8% in females) were admitted within 7 days. The main causes with more than 10% in males were injury and poisoning S00-T98 (49.8%), while those in females were injury and poisoning S00-T98 (25.2%), pregnancy and childbirth O00-O99 (19.0%), and diseases of genitourinary system N00-N99 (13.7%). Injury and poisoning S00-T98 among inpatients aged <20 years was 81.8% in males and 59.0% in females. Among those aged 20-59 years, it was 49.9% and 22.4%, and among those aged ≥60 years it was 22.3% and 16.9%, respectively. This is the first report on the frequencies of main diseases among inpatients in Lao PDR. Injury was the first main cause of admission at the tertiary hospital.

    BACKGROUND: Cyberbullying is a global public health concern with tremendous negative impacts, not only on the physical and mental health of students but also on their well-being and academic performance. However, there are very few studies on cyberbullying among university students, especially in Myanmar. This study aims to determine the percentage of university students who suffered cyberbullying victimization in the last 12 months, and the association between students' socio-demographic characteristics, adverse events following cyberbullying and cyberbullying victimization. METHODS: A cross-sectional study was conducted among university students aged 18 years and older at one medical university in Magway, Myanmar. A total of 412 students (277 males and 135 females) participated in the study. Data were collected from August to September, 2018 using a self-administered questionnaire. Multiple logistic regression analyses (models I and II) were performed to estimate the unadjusted (UOR) and adjusted odds ratios (AOR), and 95% confidence intervals (CI). RESULTS: In total, 40.8% of males and 51.1% of females in the study had suffered cyberbullying victimization in the past 12 months. In model I, students who had been studying at the university for 3 years or less (AOR = 1.81; 95% CI 1.14-2.85), and who had witnessed psychological, physical or sexual violence, or cyberbullying in their neighborhoods, (AOR = 2.95; 95% CI 1.48-5.91) were more likely to have suffered cyberbullying victimization in the past 12 months. In model II, being a victim of cyberbullying was associated with difficulties in concentrating and understanding lectures (AOR = 3.96; 95% CI 1.72-9.11), and substance abuse (AOR = 2.37; 95% CI 1.02-5.49). Non-resident students were at a higher risk of being cyberbullying victims than their resident peers (AOR = 1.86; 95% CI 1.04-3.34). CONCLUSION: Two out of five students had suffered cyberbullying victimization in the past 12 months, and only half of the victims discussed their experience(s) with someone else. Students who suffered cyberbullying victimization faced academic difficulties and started or increased smoking, betel chewing or alcohol drinking. Counter measures to prevent and mitigate the adverse events related to cyberbullying victimization are urgently needed among university students in Myanmar. Periodic screening for cyberbullying, counseling services, cyber-safety educational programs, and awareness raising campaigns should be implemented.

    Gestational trophoblastic diseases (GTDs) are a group of diseases characterized by abnormal cellular proliferation of atypical trophoblasts. A hydatidiform mole is an abnormal pregnancy caused by genetic fertilization disorders, and it can be classified as a complete hydatidiform mole (CHM) or a partial hydatidiform mole. The aim of this study was to establish cell lines from CHMs and to characterize the cells for future studies concerning GTD. HMol1-2C, HMol1-3B, HMol1-8 and HMol3-1B were established from primary cultures of CHM explants following the introduction of different combinations of genes including human telomerase reverse transcriptase (hTERT), a mutant form of CDK (CDK4R24C), cyclin D1, p53C234, MYC and HRAS. HMol1-2C, HMol1-3B, and HMol3-1B were confirmed to originate from trophoblasts of androgenic, homozygous CHMs. These three cell lines exhibited low human chorionic gonadotropin secretion, low migration and invasion abilities, and the potential to differentiate into syncytiotrophoblastic cells via forskolin treatment. These results suggest that these cells exhibit characteristics of trophoblastic cells, especially cytotrophoblastic cells. HMol1-8 was found to consist of diploid cells and originated from maternal cells, suggesting that they were derived from decidual cells. In conclusion, we successfully established three cell lines from CHMs by introduction of hTERT and other genes. Analysis revealed that the genetic origin of each cell line was identical with that of the original molar tissue, and the cell lines exhibited characteristics of trophoblastic cells, which are similar to undifferentiated cytotrophoblasts.

    OBJECTIVE:
    Choriocarcinoma is the most common epithelial cancer among gestational trophoblastic diseases (GTDs); the mechanism of trophoblastic carcinogenesis is unknown. This study aimed to examine the expression of NF-κB family proteins in GTDs and placental tissues as well as the roles of c-Rel in choriocarcinoma.
    METHODS:
    We examined the expression of NF-κB family proteins in normal placenta and hydatidiform mole tissues as well as extravillous trophoblast (EVT) and choriocarcinoma cell lines by Western blot and immunohistochemistry. Immunoprecipitation was performed to determine which proteins can bind with c-Rel in choriocarcinoma cells. To investigate the roles of c-Rel in choriocarcinoma, we examined the effects of c-Rel knockdown and overexpression on cell proliferation, migration, and invasion using small interfering RNAs and gene activation plasmid.
    RESULTS:
    The expression of c-Rel was strong in choriocarcinoma and EVTs, but very weak in villi of normal placenta and hydatidiform mole. Immunoprecipitation suggested that c-Rel heterodimerizes with p65 in choriocarcinoma. c-Rel knockdown reduced invasion, migration, and AKT phosphorylation in choriocarcinoma cells. c-Rel overexpression in choriocarcinoma increased migratory and invasive abilities, and the effect on invasion was inhibited by a PI3K inhibitor.
    CONCLUSION:
    These findings suggest that c-Rel might play a role in promoting the invasion of choriocarcinoma cells through PI3K/AKT signaling.

    Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had choriocarcinoma with metastases to the lungs, liver and kidneys. The 5th and 6th regimens with cisplatin for choriocarcinoma failed and the patient developed brain metastases. She was then treated with four cycles of high-dose ifosfamide, carboplatin and etoposide (ICE) with blood progenitor cell support after confirming the effectiveness of ICE at normal doses. The serum human chorionic gonadotropin (hCG) level was 140,009 mIU/ml at the start of high-dose ICE and the patient tolerated this regimen well. However, the beneficial effect was decreasing with each successive course of treatment, with the lowest level of hCG at 103 mIU/ml after the fourth course. The patient did not achieve complete remission and succumbed to the disease 4 months after the last chemotherapy. The findings of the present case and a review of the related literature suggest that high-dose ICE with stem cell rescue may be considered as a viable treatment option for a multi-drug resistant choriocarcinoma or GTN.

    OBJECTIVE: To investigate gestational trophoblastic neoplasia (GTN), fertility, and pregnancy outcome in molar patients who underwent routine second curettage.
    STUDY DESIGN: Eighty-two patients who visited our hospital for hydatidiform mole between 2002 and 2011 were registered in this study. All patients had second curettage around the 7th day after first evacuation. We performed retrospective analysis on several factors between a remission group and a GTN group.

    RESULTS: Fourteen patients (17.1%) had chemotherapy after being diagnosed with GTN. Multivariate analysis revealed that the hCG value before first evacuation was only one independent prognostic factor for GTN. The median follow-up period was 45.5 months, and 41 patients had 62 pregnancies after remission of hydatidiform mole and GTN. The fertility rate was 80% in 45 patients with desire for a baby, and 39 pregnancies (62.9%) ended in live births without congenital malformation.

    CONCLUSION: The incidence of GTN was not lower in hydatidiform mole with routine second curettage. An independent prognostic factor for GTN was the hCG value before the first evacuation in molar patients. Our results suggest that routine second curettage does not affect the fertility rate or increase a risk of adverse outcomes in subsequent pregnancies.

    Objectives: Hyperglycosylated hCG (hCG-H) is a glycoprotein variant of the hormone hCG and reported to be detected in serum and urine of early pregnant women, invasive mole and choriocarcinoma, but not of molar patients. N-acetylglucosaminyltransferase IVa (GnT-IVa) is one of glycosyltransferases to attach abnormal biantennary N-linked sugar chains to hCG. Our aim is to clarify the expression of GnT-IVa in gestational trophoblastic disease and extravillous trophoblasts (EVTs) in human placenta.

    For the purpose of not only the development of obstetrics and gynecology in Vietnam, but also creation of evidence worldwide and building of medical research resources to Japan, we investigated obstetric management and gynecological rare tumor in Vietnam at several facilities in Vietnam. In the present study, several findings, which are related to improvement of mothers and children's prognosis,were gained. First, Pregnancy with dengue fever causes thrombocytopenia, which is at risk of postpartum hemorrhage. Second, cesarean section scar pregnancy with an increase in cesarean section rate in Vietnam, could be managed by medication for only selected patients. Third, evaluation of cardiac function by ultrasound examination for fetal growth restriction would be beneficial. Lastly, we found that there was a high secondary rate after molar pregnancy in Vietnam and preventive measures might improve it.

    Choriocarcinoma cell line with GnT-IVa overexpression (Jar/GnT-IVa) was established and shRNA vectors were made for knockdown of GnT-III expression. GnT-III shRNA vectors were introduced into Jar/GnT-IVa. The levels of sugar chains were not changed by knockdown of GnT-III. Sandwich ELISA was performed using conditioned medium of Jar and GnT-IVa KD (Jar with knockdown of GnT-IVa expression), GSL-II lectin and a mouse antibody.
    Whole cell lysate and conditioned medium were collected from Jar/GnT-IVa and control cells. Nano-LC/MS/MS analysis using the proteins showed that LAMP-2 was a target molecule of GnT-IVa.

    The structures of sugar chains of hCG are quite different in trophoblastic neoplasia compared with normal pregnancy and hydatidiform mole, and it is because of N-acetylglucosaminyltransferase IVa (GnT-IVa)and core 2 beta-1, 6-N-acetylglucosaminyltransferase (C2GNT). The expression of GnT-IVa and C2GNT was strong in choriocarcinoma and invasive mole, but very weak in normal placenta and hydatidiform mole. The two glycosyltransferases involoved in promoting of invasion ability in choriocarcinoma. The result of immunoprecipitation suggested that Gnt-IVa promotes invasion ability via glycosylation of beta1 integrin. Luiferase assay suggested that cRel may regulate transcription of GnT-IVa via binding to the promoter of GnT-IVa.

    N-acetylglucosaminyltransferase V (GnT-V) is expressed in extravillous trophoblast (EVT) of human placenta in the first-trimester. We investigated factors which regulate expression of GnT-V in EVT cells using EVT cell line, HTR-8/SVneo. The supernatant of decidual tissue culture made GnT-V expression reduced and we confirmed TGF-b was the factor in cytokines. Hypoxia (1% Oxygen) promoted GnT-V expression in mRNA and protein levels after incubation for 48 hours compared to normoxia. Because GnT-V regulates trophoblast invasion by glycosylation of integrina5b1, we investigated the affection on phosphorylation of FAK after incubation with fibronectin. The result was that phosphorylation of FAK was reduced in GnT-V shRNA transfectants copared to control cells. We also investigated the difference of GnT-V expression between normal placentas and pregnancy-induced hypertension's ones, but there was no difference in immunohistochemistry and Western blot.

    GnT-V発現抑制絨毛外栄養膜細胞(EVT)モデルとして絨毛癌細胞株JarにsiRNAレトロウイルスベクターを遺伝子導入し、機能実験を行った。siGnT-V導入株ではmock株に比べて、MTS assayによる96時間までの増殖能に差は見られなかった。Migration assayおよびmatrigel invasion assayでは遊走細胞は2.1倍に、浸潤細胞は3.4倍に亢進した。
    GnT-V発現抑制による浸潤能促進機構を明らかにするために、zymographyによるmatrix metalloproteinase活性の変化を確認したが、MMP-2,MMP-9活性ともに変化は認めなかった。次に、細胞外基質への接着能を検討すると、ラミニン、フィブロネクチン、コラーゲンIおよびIVすべてにおいて接着能は亢進していた。絨毛細胞が浸潤能を持つEVTに分化するときには、膜表面に発現するインテグリンのサブタイプが基質の変化とともに変化し、浸潤に最も重要であるのはα5β1インテグンである。インテグリサブタイプの発現をフローサイトメトリーで確かめると、α1,α5,α6,β1インテグリンすべてに発現変化は認めなかった。しかし、α5β1インテグリンによる免疫沈降後にL_4-PHAを用いたレクチンブロットを行うと、α5β1インテグリンヘのβ1-6GlcNAc鎖付加レベルがGnT-V抑制株において明らかに抑制されていた。免疫沈降後に行ったα5、β1インテグリン抗体を用いたWesternblotでもそれぞれの蛋白発現レベルに変化は認めなかった。
    以上より、ヒトEVTにおいてはGnT-Vがα5β1インテグリンにβ1-6-G1cNAc鎖を付加することによって、浸潤を抑制している可能性が示唆された。細胞における分子の機能は、蛋白発現レベルのみでなく糖鎖修飾によってさらに制御されることは、今後の研究においても重要な視点である。

    There are three distinct stages to the research project:
    <BR>
    Stage 1 - Conducting an in-depth analysis of the current state of EMP delivery at Japanese universities.
    Stage 2 - Designing and creating a pilot version of an EMP MOOC for Japanese medical students.
    Stage 3 - Monitoring the efficacy of the EMP MOOC and improving the EMP content based on feedback from students, educators, and in-service doctors.
    The researchers have started their investigation into the current state of English for Medical Purposes (EMP) delivery at Japanese universities. Research on existing online EMP support material which has been designed for medical students has begun. EMP educators and medical practitioners have been contacted with a view to setting up interviews on Japanese medical students’ EMP needs and possible content for the EMP MOOC.
    Due to the Corona virus epidemic interviews with EMP educators, medical practitioners, and members of the Japan Society for Medical English Education (JASMEE) had to be rescheduled for later this year.
    In stage 3, a cohort of third- and fourth-year Japanese university medical students will be asked to use the EMP MOOC and give feedback on the design of the units and the material. Practicing physicians will also be asked to provide their feedback on the material. The research team will collect data on the efficacy of the pilot EMP MOOC through the students’ comments on each unit using an online questionnaire, focus group interviews, and one-to-one interviews. Data will be analyzed using quantitative and qualitative methods and used to refine the EMP MOOC with a view to making it available for all medical students, medical practitioners, and universities within Japan at a future date.
