Infection prevention and control status at public hospitals and factors associated with COVID-19 infection among healthcare workers in Myanmar: A cross-sectional study.

BACKGROUND: Hospitals should prepare for emerging diseases and protect healthcare workers (HCWs) from work-related infection. This study aims to assess public hospital preparedness for the coronavirus disease 2019 (COVID-19) a year after the Myanmar government began implementing COVID-19 prevention measures, and to identify factors associated with work-related COVID-19 infection among HCWs in Myanmar. METHODS: In January 2021, data were collected from 101 hospitals and 706 HCWs who had COVID-19 in Myanmar in 2020. Data from the hospitals included basic information, the status of infection prevention and control (IPC), the preparedness for COVID-19 (guidelines, checklists, fever screening, patient pathway, and training), handwashing facilities, and availability of personal protective equipment (PPE). Data of COVID-19 infected HCWs included age, occupation, workplace, severity and source of COVID-19 infection, knowledge and practice of handwashing, and working environment. Chi-square test was performed to compare the preparedness for COVID-19 among three hospital levels (primary, secondary and tertiary levels). Logistic regression analysis was performed to identify the associated factors of work-related infection of HCWs. RESULTS: The total number of beds, HCWs, and COVID-19 patients in 2020 at the 101 hospitals was 12,888, 14,421, and 19,835, respectively. The availability of PPE was high in hospitals at all levels. Approximately 80% of hospitals had functional status of IPC, set up fever screening and patient pathway, and provided training on IPC and COVID-19. However, only 39.6% of hospitals had developed COVID-19 guidelines and 55.4% had developed checklists. The percentage of hospitals that prepared each measurement was lowest at the primary level. The factors associated with work-related COVID-19 among HCWs were being 30-39 years old, working as a doctor, working at isolation wards, having disinfection technique training, and having enough PPE at the workplace. CONCLUSION: The preparedness for COVID-19 at public hospitals in Myanmar in January 2021 was insufficient, especially in the availability of the guidelines and checklists and at primary hospitals. A support system for hospital pandemic preparedness and monitoring of IPC implementation is needed. The government should prepare for emerging diseases and provide appropriate and adequate PPE and additional training to all HCWs, especially HCWs who work for isolation wards.

Historical Account of Managing Overabundant Wild Asian Elephants in Myanmar by the Kheddah System of Capture: Philosophy, Principles and Practices.

When standard methods of human-elephant conflict mitigation are not successful, free-ranging wild elephants may continue to come into close contact with people. This results in more frequent and severe conflict, with consequences ranging from crop raiding to loss of human and elephant lives. Understandably, in such situations, local communities may want to be rid of entire herds of elephants. Historically, one of the strategies the Myanmar Government practiced to resolve human-elephant conflict was the capture of whole herds using the Kheddah system. This involved trapping the herd in a stockade, immediately followed by on-site post-capture taming. After taming, the captured elephants were utilized as logging elephants. Elephants worked in timber extraction, retired at age 55 years and were then cared for by the Government until they died. The capture of wild elephants by the Kheddah system was formally banned in Myanmar in 1985 but occasional, small-scale, captures were allowed until 2013 under the strict control of the Myanmar Government. These operations were aimed primarily at capturing elephants involved in human-elephant conflict, rather than to supplement the working elephant population. One of the last Kheddah operations, organized and managed by the author, was conducted in 1996 at the Taikkyi township of the Yangon Region, as a last resort to end human-elephant conflict in an emergency. While chemical immobilization was being used at this time, it was not logistically possible with the high numbers of elephants engaged in the conflict. This review aims to record the history of an activity that was an important element of Myanmar's timber industry more than three decades ago. In this paper, the author presents a description of Kheddah not to endorse it, but to document (1) the Myanmar elephant population management strategy in the past, before it is forgotten, and (2) the practicality of the Kheddha operation when the singly selected commonly- used immobilization or noosing method of elephant capture is unfeasible. The author attempts to shed light on the modern veterinary procedures that may significantly reduce the notorious historical outcome of Kheddha, especially the resulting mortality of captured elephants, should the Kheddha system of capture ever be used as an emergency solution for ongoing problems of human-elephant conflict in the range states of Asia.

Breast Health Perceptions and Screening Behaviors Among Myanmar American Immigrant Women.

OBJECTIVES: To understand and describe attitudes toward general health checkups, breast health knowledge, cultural beliefs, and health-promoting behaviors among Myanmar American immigrant women in the United States. SAMPLE & SETTING: 267 women participated in the study. 10 women were excluded because of missing data, so the total sample size was 257 participants. METHODS & VARIABLES: A descriptive, cross-sectional survey design was used to describe and investigate breast health perceptions and behaviors. RESULTS: Nearly 75% of the study sample reported having negative attitudes toward general health checkups and were found to have less accurate breast health knowledge and more fatalistic views about breast cancer. Only 29% of older women adhered to mammogram recommendations. Younger women reported more barriers to mammograms, and older women reported fewer barriers to mammograms. IMPLICATIONS FOR NURSING: This study demonstrated the need for additional research focusing on unique perspectives when investigating breast health practices among Myanmar American immigrant women. The findings highlight the essential need to build a strong partnership with stakeholders to combat breast health disparities and address the complex nature of acculturation.

"I will take part in the revolution with our people": a qualitative study of healthcare workers' experiences of violence and resistance after the 2021 Myanmar coup d'etat.

BACKGROUND: In Myanmar, ongoing conflict since the 2021 military coup d'etat has been characterized by targeted violence against health workers (HWs), particularly those participating in the pro-democracy movement. Existing knowledge about the challenges faced by health workers in Myanmar is scant, including their perspectives on mitigating their suffering and the broader impact on community health. This knowledge gap prompted our study to assess the extent of the violence, its impact on the workers and the community, and identify resource priorities. METHODS: This qualitative study employed purposive and snowball sampling to recruit health workers affiliated with the Civil Disobedience Movement (CDM). We interviewed 24 HWs in Myanmar between July and December 2022, predominantly physicians and nurses. We used a semi-structured interview guide and conducted interviews remotely due to the security situation. We adopted content analysis to understand participation in the CDM movement, experiences of violence, personal and professional impacts, the sequelae to community health, how HWs responded as well as their ongoing needs. RESULTS: Thematic content analysis revealed that violence was both individually targeted and widespread. Health workers faced professional, financial, and personal impacts as a result. The health system as a whole has been severely diminished. Health workers have had to adapt to continue to provide care, for example some fled to rural areas and worked clandestinely, exchanging their services for food and shelter. In those settings, they continued to face insecurity from airstrikes and arrests. Health workers have also experienced moral distress and burden due to their resistance and protest against the regime. CONCLUSION: The coup and ensuing violence severely disrupted the healthcare system, resulting in shortages of supplies, reduced quality of care, and exacerbated challenges during the COVID-19 pandemic. Despite facing significant hardships, HWs remained resilient, engaging in resistance efforts within the CDM and seeking support from local communities and international organizations. They expressed a need for increased awareness, financial assistance, and concrete support for the health system to address the crisis.

Demographic and socioeconomic obstacles to access to malaria services for Myanmar migrants in Thailand.

BACKGROUND: Typically mobile and vulnerable, migrants face significant barriers to access to routine malaria prevention, diagnostics and treatment, which leads to unchecked malaria transmission, particularly in border regions with a high population displacement. This study aimed to investigate the demographic and socioeconomic obstacles to access to malaria services among Myanmar migrants residing in the Thailand-Myanmar border areas. METHODS: A cross-sectional study was conducted in early 2024 across three districts near the Thailand-Myanmar border. Quantitative data were collected from Myanmar migrants using standardized questionnaires through structured surveys. Data analysis included descriptive statistics and simple and multiple logistic regression models. RESULTS: Out of 300 participants, approximately a quarter (27.3%) reported adequate access to comprehensive malaria services, including prevention, diagnostics, treatment and malaria-related health information. In multiple logistic regression models, factors associated with inadequate access included Myanmar migrants aged over 60 years (aOR: 7.63, 95% CI 1.74-20.58), accompanied by one to three family members (aOR: 3.33, 95% CI 1.06-8.45), earning monthly incomes below 3000 THB (aOR: 5.13, 95% CI 1.38-19.09) and 3000 to 6000 THB (aOR: 3.64, 95% CI 1.06-12.51), belonging to the Karen ethnicity (aOR: 2.13, 95% CI 1.02-3.84), with poor perception toward malaria (aOR: 2.03, 95% CI 1.03-4.01) and with poor preventive and health-seeking practices (aOR: 5.83, 95% CI 2.71-9.55). CONCLUSIONS: A significant proportion of Myanmar migrants encounter demographic and socioeconomic barriers to access to routine malaria services in Thailand. Tailored interventions are required to expand such access, including the recruitment of worksite health volunteers, strengthening the role of ethnic health organizations across the border and collaboration with private sector stakeholders (e.g. farm/company owners) to distribute preventive tools and ensure timely referral of suspected malaria cases to health facilities.

Myanmar immigrant women's perceptions, beliefs, and information-seeking behaviors with nutrition and food practices during pregnancy in Thailand: a qualitative study.

BACKGROUND: Although nutrition is an essential contributor to the quality of pregnancy outcomes, little is known about the experiences and influences affecting dietary behaviors during pregnancy among migrant women, particularly those from Myanmar, the largest immigrant population in Thailand. To fill this gap, we conducted a descriptive qualitative study to explore Myanmar immigrant women's perceptions, beliefs, and information-seeking behaviors concerning nutrition and food practices during pregnancy. METHODS: We conducted focus group discussions (FGDs) with fifty Myanmar immigrant pregnant women aged 18-45 years across all trimesters, who were recruited using purposive sampling from a public tertiary hospital. The FGDs were conducted in Thai or Myanmar using semi-structured guides that probed women's pregnancy perceptions and experiences about nutrition and food patterns during pregnancy. The FGDs were audio-recorded, translated, and transcribed. Direct content analysis was used to guide the analysis through an ecological perspective framework. RESULTS: The seven FGDs with fifty women revealed four major themes involving perceptions, beliefs, and information-seeking behaviors. The qualitative results consisted of (1) a positive attitude toward better changes under difficult conditions (setting goals for infant health; uncertainty about changes); (2) beliefs about eating patterns and dietary practices during pregnancy (taboos aimed at protecting women's health and ensuring safe childbirth; taboos aimed at guaranteeing infant safety); (3) limited access to appropriate information about nutrition (unclear dietary information from healthcare providers; ease of learning from experiences in informal social networks); and (4) difficult living conditions in a non-native setting (work-related influences on dietary behaviors; lack of comprehensible language to gain food literacy). In addition, the results were highlighted across four levels of ecological perspectives. CONCLUSIONS: Immigrant pregnant women are a vulnerable population that should be treated with equity to ensure quality of life through optimal nutrition throughout pregnancy. Respectful care requires that healthcare providers develop culturally sensitive nutrition interventions to increase nutrition literacy, accessibility, and pregnancy outcomes.

Prevalence and Risk Factors of Giardia intestinalis Infestation and Assemblage of Isolates Among Monastery Primary School Children in Yangon, Myanmar.

Giardiasis is one of the major causes of diarrhea among children. To determine the prevalence, risk factors, and genotype of Giardia intestinalis, a cross-sectional descriptive study was done on stool samples of 462 children attending three monastery primary schools from North Okkalapa Township in Yangon, Myanmar from January 2016 to February 2019. Socioeconomic data were collected using a pre-tested questionnaire after obtaining informed consent. Direct wet mount, formalin-ether sedimentation, and trichrome staining techniques were used for the primary identification and then molecular identification was carried out by conventional polymerase chain reaction (PCR)-sequencing assay. G. intestinalis was identified in 11.7% (54/462) of students. There was no significant association with water source (p=0.948) and drinking untreated water (p=0.595). The infection was more common in children with low-educated parents, unsanitary garbage disposal practices, and no restrooms. All isolates were G. intestinalis assemblage B. This is the first study characterizing human isolates in a lower region of Myanmar, at the molecular level [MOU1]. These findings pointed out the high prevalence of G. intestinalis among primary school children from densely populated and low-resource settings.

Factors associated with the uptake of COVID-19 vaccination, testing and medical care among Myanmar migrants in Japan: a cross-sectional study.

BACKGROUND: Migrants are individuals who move to a different country from their usual place of residence. Japan's migrant population, particularly technical interns and students, has been growing. Even before the pandemic, previous studies have highlighted difficulties faced by migrants in utilizing healthcare services. This study examined the uptake of COVID-19 vaccination, testing, and medical care among Myanmar migrants in Japan; identified the factors associated with this uptake; and described the difficulties encountered when utilizing these services. METHODS: A cross-sectional study was conducted between March and April 2023 targeting Myanmar migrants over 18 years residing in Japan for more than 6 months. An online self-administered questionnaire in Myanmar language covered socioeconomic characteristics; history of COVID-19 vaccination, testing, and medical care; and difficulties encountered while utilizing these services with multiple-choice questions. Multivariate logistic regression analysis was performed separately to identify the factors associated with the uptake of COVID-19 vaccination, testing, and medical care. RESULTS: Among the 207 participants, 52% (n = 108) were under 30 years, 30% (n = 62) were male, and 31% (n = 65) were low-skilled workers (technical interns and students). Overall, 91% (n = 189) had received the COVID-19 vaccination, 76% (n = 157) had been tested for COVID-19, and 43% (n = 68) tested positive. However, only 77% (n = 52) of COVID-19 patients sought medical care. Participants under 30 years of age were less likely to receive the COVID-19 vaccine compared to those aged 30 and older (adjusted odds ratio [aOR] 0.10, 95% confidence interval [CI] 0.01-0.88, p = 0.038). Low-skilled workers were less likely to seek medical care compared to those holding other categories of residential status (aOR 0.12, 95% CI 0.02-0.79, p = 0.027). Among service users, 5% faced difficulties with COVID-19 vaccination, 10% with testing, and 17% with receiving medical care. Long waiting times and complex reservation processes were the main difficulties encountered. CONCLUSIONS: The uptake of COVID-19 vaccination, testing, and medical care in this sample was reasonably good. However, individuals under 30 years of age showed lower uptake of vaccination, while low-skilled workers had lower uptake of medical care. Strengthening education and support for young migrants and low-skilled workers regarding COVID-19 and other infectious diseases is essential, especially in workplaces and educational institutions.

Myanmar migrants living along the Thailand-Myanmar border: Experiences related to pandemic and migration decisions.

Importance: In Myanmar, amid political and civil unrest, droves of Burmese are displaced to neighboring countries including Thailand. Since the COVID-19 pandemic, little is known about the available healthcare services and health and well-being among refugees and migrant workers within resettlement areas along the Myanmar-Thailand border. Objective: To explore the unmet needs of migrants along the Thailand-Myanmar border during the COVID-19 pandemic and their reasons for leaving Myanmar. Design: A qualitative study that used focus groups with migrant schoolteachers and school masters was undertaken. An interpretative analysis approach was used to analyze the data from the focus group sessions. The study followed the COREQ (COnsolidated criteria for REporting Qualitative) checklist. Setting: In July 2022, community stakeholders from migrant schools located in the vicinity of Mae Sot, Thailand were referred to the study team. Participants: A purposive sample of 17 adult participants was recruited from 4 migrant schools. The participants were schoolteachers and schoolmasters who had traveled from Myanmar to Thailand 1 to 20 years ago. Main Outcomes and Measures: Thematic analysis was used to scrutinize qualitative data for the outcomes of health and well-being, barriers, and reasons for migration. Results: Three main themes were identified: "issues related to the pandemic", "teenage marriage and pregnancies" and "migration decisions". The issues related to the pandemic included behavior changes in children, a diminished quality of education, and barriers to receiving COVID-19 vaccines and accessing other health care. There were more dropouts due to teenage pregnancy/marriage during the shelter in place mandate. Migration decisions were affected by concerns over health, civil unrest, and military harassment. Conclusions and Relevance: This study presented the difficulties experienced by Myanmar migrants currently living along the Thailand-Myanmar border. The reasons for leaving Myanmar included health and safety. Suspending education during the pandemic caused more school dropouts due to teenage pregnancy/marriage. Additionally, behavioral changes in children, a diminished quality of education, barriers to receiving COVID-19 vaccines and access to other health care services were reported. Future studies should focus on how migration stress and access to mental health care impact the migrant population.

Negotiating and Struggling for a New Life: Stigma, Spirituality, and Coping Strategies of People Living with HIV in Myanmar.

Although enacted and internalized stigma is a continuing problem for people living with HIV (PLWH) in Southeast Asia, there is little understanding of how PLWH cope with discrimination, exclusion, and other negative outcomes caused by HIV-related stigmatization. This article aims to bridge this gap by analyzing the lived experiences of HIV-related stigmatization and coping strategies among 30 people with HIV in Myanmar, a country heavily influenced by religion, especially Buddhism. Among the 30 study participants, 20 were female and 10 were male, with ages ranging from 18 to 50 years. Through the lens of Bourdieu's concepts of habitus, field, and capital, this article first elucidates the various forms of stigmatization in family, work, social, and other settings as symbolic violence on people with HIV. The present article shows that spirituality serves as a perceptual and action framework for people with HIV to generate reflexivity toward their HIV infection and related stigmatization and to further engage in agentic responses. More importantly, this article demonstrates how people with HIV draw on spirituality to support peers in reclaiming control over their lives and how they are perceived by society. The findings indicate that the local context, especially cultural and religious resources, should be considered when developing interventions to mitigate HIV-related stigmatization in Southeast Asia.

The Impact of Stressors on Depressive Symptoms Among Youth Myanmar Migrant Workers in Thailand: A Cross-Sectional Study.

Background: Many youths suffer from depressive symptoms globally, especially youth migrant workers who are more vulnerable to depressive symptoms than non-migrant youths. Given the extensive literature reviewed, little is known about the impact of stressors on depressive symptoms among young migrant populations. Therefore, this study aimed to investigate the impact of stressors on depressive symptoms among young Myanmar migrants in Thailand. Methods: This cross-sectional analytical study was conducted between August and December 2023, using self-administered questionnaires. The sample size was 165 young migrant workers in Myanmar by simple random sampling. The exclusion criteria were participants who had serious physical illness or acute mental illness, and unwillingness to participate in the study. Sociodemographic characteristics, Rosenberg Self-Esteem Scale, and CESD (The Center for Epidemiological Studies-Depressive symptoms) were included in the questionnaires. Chi-square and Fisher exact tests were used for descriptive statistics. Hierarchical linear regression analysis was used to examine the association between stressors, self-esteem, coping behavior, and depressive symptoms. Results: It was found that 47.9% of young Myanmar migrant workers had experienced depressive symptoms. Depressive symptoms was associated with four variables: workplace stressors (ß = 0.525, p <0.001), security stressors (ß = 0.181, p <0.01), living stressors (ß = 0.126, p <0.05), and self-esteem (ß = -0.135, p <0.05). Conclusion: According to hierarchical linear regression analysis, workplace, security, and living stressors significantly increased depressive symptoms scores, whereas self-esteem decreased depressive symptoms scores among young 165 Myanmar migrant workers. Therefore, policymakers should be encouraged to establish preventive measures against specific stressors. In addition, many young migrant workers have been found to experience depressive symptoms. Mental health care should be prioritized and made accessible to this vulnerable and risky group.

Factors associated with postpartum depression among Myanmar women in Yangon: A cross-sectional study.

Background: Postpartum depression (PPD) is non-psychotic depressive illness after childbirth, and PPD affects the health and social status of mothers and their children. This study aims to identify the prevalence of suspected PPD and associated factors among women in Yangon, Myanmar. Methods: This is a cross-sectional study of 552 women at 6-8 weeks postpartum who visited at North Okkalapa General and Teaching Hospital for postnatal care from September to October 2022. Socio-demographic factors, obstetric and infant factors, family support, and medical history were collected using a structured questionnaire. Myanmar version of the Edinburgh Postnatal Depression Scale (EPDS) was used for screening PPD, and all women were divided into suspected PPD (EPDS ≥10) and non-suspected PPD (EPDS <10). Chi-square and Fisher's exact tests were used to compare the characteristics of women between suspected PPD and non-suspected PPD. Logistic regression analysis was preformed to identify the factors associated with suspected PPD. Results: The mean age of the 552 women was 27.9 years and 176 women (31.9 %) were categorized into suspected PPD. Factors associated with suspected PPD were living in a nuclear family (adjusted odds ratio (AOR) = 2.04, 95 % confidence interval (CI) 1.10-3.77), feeling insufficient income (AOR = 2.15, 95 % CI 1.09-4.25), unplanned pregnancy (AOR = 2.76, 95 % CI 1.47-5.16), less than eight ANC visits (AOR = 3.29, 95 % CI 1.74-6.23), low birth weight of the last baby (AOR = 5.69, 95 % CI 1.17-27.71), insufficient support from partners (AOR = 11.28, 95 % CI 5.62-22.63), parents (AOR = 3.83, 95 % CI 2.08-7.04), and parents-in-law (AOR = 2.00, 95 % CI 1.06-3.76), and depressive symptoms during the last pregnancy (AOR = 3.08, 95 % CI 1.52-6.26). Conclusion: The prevalence of suspected PPD was 31.9 % among 6-8-week postpartum women in Yangon. Strengthening maternal health programs and providing education about postpartum psychiatric problems is essential to improve maternal psychological well-being.

Health service providers' views on barriers and drivers to childhood vaccination of FDMN/Rohingya refugees: a qualitative study in Cox's Bazar, Bangladesh.

Background: Despite established vaccination programs, vaccine-preventable diseases persist among about 900,000 Forcibly Displaced Myanmar Nationals (FDMN)/Rohingya refugees in the world's largest refugee settlement in Bangladesh. Health service providers (HSPs) play a key role in the delivery of childhood vaccination programs. This study explored their views on individual and context barriers and drivers to childhood vaccination in this setting. Methods: Informed by the theoretical framework of the Capability-Opportunity-Motivation-Behavior (COM-B) model for behavior change, this qualitative study collected data through eight focus group discussions (FGDs) with community health workers (CHWs) and vaccinators in selected camps with high or low vaccination coverage rates, and through 11 in-depth interviews (IDIs) with key informants working in strategic, management, and administrative roles. Findings: Barriers and drivers were evident across all COM factors for HSPs and caregivers. Among HSPs, knowledge around vaccination acted both as a barrier and driver, while communication skills and confidence in vaccination served as drivers. Caregivers' lack of awareness of vaccination, concerns and mistrust were described as main barriers. Context barriers included information system deficiencies, family dynamics, HSPs' working conditions, and vaccination site accessibility. Context drivers included effective communication, mobilization, and incentives. Differences between high and low coverage camps in Cox's Bazar included variations in HSPs' knowledge, communication strategies, incentive use, and stakeholder collaboration. Discussion: For better vaccination coverage in the camps, context-related changes regarding collaboration, health workforce and the use of incentives seem necessary. Caregivers' mistrust toward vaccination needs to be considered under the social and historical background of the Rohingya community, and further addressed with targeted communication and campaigning.

Spatio-temporal analysis of genetic diversity of merozoite surface protein-3 alpha in Myanmar Plasmodium vivax isolates.

Myanmar aims to eliminate malaria by 2030. However, recent increase of malaria incidence is a great challenge to archive that goal. Increasing prevalence of Plasmodium vivax also hinders this endeavor. Monitoring genetic structure of the parasite is necessary to understand genetic nature and evolutionary aspect of P. vivax population in Myanmar. Partial fragment flanking blocks I and II of merozoite surface protein-3 alpha of P. vivax (pvmsp-3α) was amplified from P. vivax isolates collected in Pyin Oo Lwin, Mandalay Region, Myanmar in 2013-2015. Sequence analysis of pvmsp-3α was performed to determine genetic diversity and natural selection of this gene. Spatio-temporal genetic changes of pvmsp-3α in Myanmar P. vivax population were also investigated via comparative analysis of gene sequences obtained in this study and previously reported Myanmar pvmsp-3α sequences. Genetic diversity of Myanmar pvmsp-3α was detected in P. vivax isolates analyzed. Size polymorphisms in block I and amino acid changes and recombination events in block II were main factors contributing to the genetic diversity of pvmsp-3α. Comparative spatio-temporal analysis with previously reported Myanmar pvmsp-3α populations revealed the presence of genetic differences by population with moderate genetic differentiation between populations. Similar pattern of natural selection was also detected in Myanmar pvmsp-3α populations. These suggested that enough size of the P. vivax population sufficient to generate or maintain the genetic diversity remains in the population. Thus, continuous molecular surveillance of genetic structure of Myanmar P. vivax is necessary.

Struggling to resume childhood vaccination during war in Myanmar: evaluation of a pilot program.

BACKGROUND: After the military coup in Myanmar in February 2021, the health system began to disintegrate when staff who called for the restoration of the democratic government resigned and fled to states controlled by ethnic minorities. The military retaliated by blocking the shipment of humanitarian aid, including vaccines, and attacked the ethnic states. After two years without vaccines for their children, parents urged a nurse-led civil society organization in an ethnic state to find a way to resume vaccination. The nurses developed a vaccination program, which we evaluated. METHODS: A retrospective cohort study and participatory evaluation were conducted. We interviewed the healthcare workers about vaccine acquisition, transportation, and administration and assessed compliance with WHO-recommended practices. We analyzed the participating children's characteristics. We calculated the proportion of children vaccinated before and after the program. We calculated the probability children would become up-to-date after the program using inverse survival. RESULTS: Since United Nations agencies could not assist, private donations were raised to purchase, smuggle into Myanmar, and administer five vaccines. Cold chain standards were maintained. Compliance with other WHO-recommended vaccination practices was 74%. Of the 184 participating children, 145 (79%, median age five months [IQR 6.5]) were previously unvaccinated, and 71 (41%) were internally displaced. During five monthly sessions, the probability that age-eligible zero-dose children would receive the recommended number of doses of MMR was 92% (95% confidence interval [CI] 83-100%), Penta 87% (95% CI 80%-94%); BCG 76% (95% CI 69%-83%); and OPV 68% (95% CI 59%-78%). Migration of internally displaced children and stockouts of vaccines were the primary factors responsible for decreased coverage. CONCLUSIONS: This is the first study to describe the situation, barriers, and outcomes of a childhood vaccination program in one of the many conflict-affected states since the coup in Myanmar. Even though the proportion of previously unvaccinated children was large, the program was successful. While the target population was necessarily small, the program's success led to a donor-funded expansion to 2,000 children. Without renewed efforts, the proportion of unvaccinated children in other parts of Myanmar will approach 100%.

New Genera and Species of Trigonidiidae (Orthoptera: Grylloidea) from the Mid-Cretaceous of Myanmar with a Redescription of Birmaninemobius hirsutus.

The abundance of insects in Burmese amber illustrates a highly diverse insect community from the mid-Cretaceous period; yet, records of crickets (Grylloidea) are notably scarce. In this study, we describe two new genera with three new species, Palaeotrigonidium concavoculus gen. et sp. nov., Palaeotrigonidium defectivus sp. nov., and Tricalcaratus longilineus gen. et sp. nov., based on three specimens collected in north Myanmar. These new species can be placed within the Trigonidiidae (Orthoptera: Grylloidea) by their triangular head, compound eyes that protrude in dorsal view, and a body entirely covered with robust setae, particularly noticeable in the head and pronotum; however, subfamily assignments are not possible. Another known species, Birmaninemobius hirsutus, Xu et al., 2020, from Myanmar amber is redescribed based on a new specimen and a recheck of the holotype.

A new multivariate index for ecological security assessment in the China-Myanmar border region.

The coordination of development efforts and ecological conservation in China's border regions is a significant challenge due to the overlap of biodiversity hotspots, ecologically fragile zones, and impoverished areas. Achieving the harmonious integration of ecological preservation and economic development relies on the fundamental assessment of ecological security (ES). However, comprehensive assessments of ES in border regions remain limited. This study introduces a new index, the multivariate ecological security index (MESI), which integrates ecosystem vigor, organization, elasticity, services and risk. Here, the MESI was utilized to assess the temporal and spatial changes in ES and its associated impact factors in the China-Myanmar border region (CMBR) from 2000 to 2020. The MESI provides a clear representation of the actual ES status in the CMBR, exhibiting a significant correlation with the eco-environmental quality index (EEQI; p < 0.01). The ES status exhibited notable spatial heterogeneity in the CMBR, consisting primarily of both relatively safe and safe levels, which accounted for approximately 85% of the total area. From 2000 to 2020, the CMBR experienced a gradual improvement in ES status, with the area experiencing an increase in the ES level accounting for 23.41% of the total area, which exceeded the proportion of the area experiencing a decrease in the ES level (4.71%). The combined impact of multiple factors exerted a greater influence on ES than did individual factors alone. Notably, human factors increasingly influenced the ES status during the study period. The results of this study provide valuable insights for ecological preservation and sustainable management in the CMBR, and the MESI can be extended to assess the ES of other regions.

Development of a bioelectrical impedance analysis-based prediction equation for body composition of rural children aged 4-8 years in Myanmar.

Background: Reliable and accurate estimates of body composition are essential when studying the various health correlates of disease. Bioelectrical impedance analysis (BIA) is an affordable and feasible body composition assessment technique for clinical and field settings. Total body water (TBW) and hence fat-free mass is estimated by predictive regression algorithms using anthropometric measurements plus the resistance index. Aim: The study aimed to develop a BIA prediction equation for TBW in children in Myanmar using the deuterium dilution technique as the reference method. Methods: The study design was cross-sectional in a school setting with convenience sampling of participants. One hundred and two healthy children (57 boys and 45 girls) with aged 4 and 8 years participated; randomly divided into the prediction group (29 boys and 22 girls) and cross-validation group (28 boys and 23 girls). Whole-body impedance, anthropometric and TBW (by D2O dilution) measurements. The prediction equation was cross-validated using a split-group design and compared to published equations for contemporaneous populations. Results: TBW could be predicted by the following equation. TBW = 0.4597 * Weight (kg) + 0.1564 * Impedance index + 0.6075 (R2 = 0.891, P < 0.0001) with a correlation coefficient of 0.942 and limits of agreement of 0.98 kg TBW on cross-validation. Conclusions: This equation can be used to predict body composition in young (aged 4-8 years) children in Myanmar but because the age range of the participants in the present study was relatively narrow, more research in different age groups is required to establish its broader applicability.

The First Cretaceous Epyrine Wasp (Hymenoptera: Bethylidae): A New Genus and Species from Early Cenomanian Kachin Amber.

The Epyrinae are the second largest subfamily of Bethylidae and the most diverse in the fossil record. However, although six of the nine bethylid subfamilies are known during the Cretaceous (either as compression or amber fossils), the Epyrinae were hitherto unknown before the lower Eocene. In this contribution, we report the discovery of the oldest member of this group, based on a female specimen from the early Cenomanian amber of Kachin, Myanmar. We describe and illustrate a new genus and species, Hukawngepyris setosus gen. et sp. nov. The new genus is compared with the other epyrine genera and characterized by a unique combination of characters not known in the subfamily. Hukawngepyris setosus gen. et sp. nov. is especially unique in the configuration of the forewing venation, with a complete 2r-rs&Rs vein, curved towards the anterior wing margin, and the presence of three proximal and three distal hamuli. The key to the genera of Epyrinae is accommodated to include the newly erected genus.

Genetic Diversity and Natural Selection of Plasmodium vivax Merozoite Surface Protein 8 in Global Populations.

Plasmodium vivax Merozoite Surface Protein 8 (PvMSP8) is a promising candidate target for the development of multi-component vaccines. Therefore, determining the genetic variation pattern of Pvmsp8 is essential in providing a reference for the rational design of the P. vivax malaria vaccines. This study delves into the genetic characteristics of the Pvmsp8 gene, specifically focusing on samples from the China-Myanmar border (CMB) region, and contrasts these findings with broader global patterns. The study uncovers that Pvmsp8 exhibits a notable level of conservation across different populations, with limited polymorphisms and relatively low nucleotide diversity (0.00023-0.00120). This conservation contrasts starkly with the high polymorphisms found in other P. vivax antigens such as Pvmsp1. A total of 25 haplotypes and 14 amino acid mutation sites were identified in the global populations, and all mutation sites were confined to non-functional regions. The study also notes that most CMB Pvmsp8 haplotypes are shared among Burmese, Cambodian, Thai, and Vietnamese populations, indicating less geographical variance, but differ notably from those found in Pacific island regions or the Panama. The findings underscore the importance of considering regional genetic diversity in P. vivax when developing targeted malaria vaccines. Non departure from neutral evolution were found by Tajima's D test, however, statistically significant differences were observed between the kn/ks rates. The study's findings are crucial in understanding the evolution and population structure of the Pvmsp8 gene, particularly during regional malaria elimination efforts. The highly conserved nature of Pvmsp8, combined with the lack of mutations in its functional domain, presents it as a promising candidate for developing a broad and effective P. vivax vaccine. This research thus lays a foundation for the rational development of multivalent malaria vaccines targeting this genetically stable antigen.
