Rural-urban inequalities in health care utilization in Bhutan: a decomposition analysis.

BACKGROUND AND OBJECTIVE: On the trajectory towards universal health coverage in Bhutan, health equity requires policy attention as significant disparities exist between urban and rural health outcomes. This paper examines health services utilization patterns, inequalities and their socio-economic determinants in rural and urban areas and decomposes the factors behind these differences. METHODS: We used the Bhutan Living Standard Survey 2017 to profile health services utilization patterns and equalities. We employed two different decomposition analyses: decomposition of mean differences in utilization using the Oaxaca-Blinder decomposition framework and differences in the income-related distribution in utilization using recentered influence function regressions between rural and urban areas. RESULTS: Significant differences exist in the type of outpatient services used by the rural and urban population groups, with those living in rural areas having 3.4 times higher odds of using primary health centers compared to outpatient hospital care. We find that the use of primary health care is pro-poor and that outpatient hospital resources is concentrated among the more affluent section of the population, with this observed inequality consistent across settings but more severe in rural areas. The rural-urban gap in utilization is primarily driven by income and residence in the eastern region, while income-related inequality in utilization is influenced, aside from income, by residence in the central region, household size, and marriage and employment status of the household head. We do not find evidence of significant mean differences in overall utilization or inequality in utilization of inpatient health care services. CONCLUSIONS: While the differences in average contacts with health services are insignificant, there are prominent differences in the level of services availed and the associated inequality among rural and urban settings in Bhutan. Besides, while there are obvious overlaps, factors influencing income-related inequality are not necessarily the same as those driving the utilization gaps. Cognizance of these differences may lead to better informed, targeted, and potentially more effective future research and policies for universal health coverage.

A quality of care assessment for women of childbearing potential with epilepsy in Bhutan: An observational study.

BACKGROUND & OBJECTIVE: In lower-middle income countries such as Bhutan, the treatment gap for epilepsy is over 50% as compared to a treatment gap of less than 10% in high-income countries. We aim to analyze the quality of epilepsy care for women of childbearing potential in Bhutan using the Quality Indicators in Epilepsy Treatment (QUIET) tool, and to assess the usefulness of the tool's section for women with active epilepsy (WWE) in the Bhutanese setting. METHODS: A prospective convenience cohort was enrolled in Thimphu, Paro, Punakha, and Wangdue, Kingdom of Bhutan, in 2022. Bhutanese women of childbearing potential at the time of enrollment (18-44 years old) were evaluated for the diagnosis of active epilepsy and underwent a structured survey-based interview with Bhutanese staff. Participants were surveyed on their epilepsy, pregnancy, and antiseizure medicine (ASM) histories. The clinical history and quality of epilepsy care of adult WWE were assessed using a section of the QUIET tool for women, an instrument originally developed by the U.S. Department of Veterans Affairs to analyze the quality of epilepsy care for American adults. RESULTS: There were 82 Bhutanese WWE of childbearing potential, with mean age of 30.6 years at enrollment (range 18-44, standard deviation (SD) 6.6) and mean age of 20.3 years at epilepsy diagnosis (range 3-40, SD 8.0)). 39 % (n = 32) had a high school or above level of education, and 42 % (n = 34) were employed. 35 % (n = 29) reported a seizure within the prior week, and 88 % (n = 72) reported a seizure within the prior year. 49 % (n = 40) of participants experienced > 100 lifetime seizures. All but one participant took antiseizure medications (ASMs). At enrollment, participants presently took no (n = 1), one (n = 3), two (n = 37), three (n = 25), four (n = 11), or over five (n = 5) ASMs. The most common ASMs taken were levetiracetam (n = 40), phenytoin (n = 27), carbamazepine (n = 23), phenobarbital (n = 22), and sodium valproate (n = 20). 61 % of all WWE took folic acid. Of the 40 previously pregnant WWE, eight (20 %) took folic acid during any time of their pregnancy. 35 % (n = 29) used betel nut (doma, quid) and 53 % (n = 21) of pregnant WWE used betel nut during pregnancy. CONCLUSIONS: Based on data about WWE participants' ASM, supplement, and substance use, our study identified the high use of first generation ASMs (including valproate), frequently in polytherapy, and betel nut use as treatment gaps in women of childbearing potential age with active epilepsy in Bhutan. To address these gaps for locations such as Bhutan, we propose modifications to the QUIET tool's "Chronic Epilepsy Care for Women" section.

Revolution of Helicobacter pylori treatment.

Helicobacter pylori infection is a major global health concern, and its management has witnessed a revolutionary shift with the emergence of antibiotic resistance. In this review, I explore the mechanisms of H. pylori antibiotic resistance and highlight the critical need for susceptibility-based eradication treatments. The increasing prevalence of antibiotic-resistant strains requires innovative approaches to combat this resilient pathogen. I also delve into the importance of mass screening as a preventive strategy for early detection and intervention, describing my experience in Bhutan. Additionally, I explore promising alternatives, such as vaccination. The aim of this review is to provide insight into the evolving landscape of H. pylori treatment and highlight the need for a paradigm shift in the approach to combating this persistent bacterial infection.

CASE PRESENTATION: Herein, we present a case of cervical cancer (FIGO stage IB3) diagnosed at 28+ 5 weeks and successfully managed at 37+ 2 weeks of gestation in a 27-year-old woman. CONCLUSION: This is the first case report on cervical cancer in pregnancy from Bhutan. It highlights the diagnostic and management challenges in a low resource country.

Rate and risk factors of inadequate endometrial tissues after endometrial sampling among Bhutanese women at the national referral hospital of Bhutan: a cross-sectional study.

INTRODUCTION: Women presenting with abnormal uterine bleeding needs careful and thorough assessment including ultrasound examination of endometrium and histopathological assessment of the endometrial tissues. The objective of this cross-sectional study was to determine the rate and the factors associated with inadequate endometrial tissues after endometrial sampling using MedGyn® pipette among Bhutanese women at the colposcopy clinic, Jigme Dorji Wangchuck National Referral Hospital (JDWNRH), Bhutan. METHODS: This cross-sectional study was conducted at the colposcopy clinic, JDWNRH, Thimphu between October, 2021 and March, 2022. Women included in this study underwent endometrial sampling using MedGyn® pipette without anesthesia as an office procedure. Data were collected using an interviewer-administered questionnaire and results extracted into a structured pro forma. The histopathology reports were extracted from the Department of Pathology and Laboratory Medicine, JDWNRH using the unique Bhutanese citizenship identity card number of the study participants. RESULTS: Inadequate endometrial tissues were noted in 27% (33 out of 122 cases). Among 89 patients with an adequate endometrial tissue, histologic results were normal in 30 (33.7%), benign pathology in 22 (24.7%), atrophy in 10 (8.2%), and hyperplasia in 27 (30.3%). In a univariate analysis, menopausal state (OR 1.6, 95% CI 0.708-3.765), overweight and obese (OR 1.6 95% CI 0.640-3.945), unemployed (OR 1.7, 95% CI 0.674-1.140), nulliparous (OR 1.7, 95% CI 0.183-15.816), primipara (OR 5.1, 95% CI 0.635-40.905) and use of hormonal contraception (OR 2.1, 95% CI 0.449-10.049) were associated with increased risk of inadequate endometrial tissues. On multivariate regression analysis, nulliparity (OR 1.1, 95% CI 0.101-12.061), overweight and obesity (OR 1.4, 95% CI 0.490-3.917), use of hormonal contraceptives (OR 2.2, 95% CI 0.347-13.889), and junior surgeons (OR 1.1, 95%CI 0.463-2.443) were found to be associated with inadequate endometrial tissues. However, the above associations were not statistically significant (p > 0.05). CONCLUSION: The rate of inadequate endometrial tissue following endometrial sampling using MedGyn® pipette was 27.0%. Factors associated with an increased risk of inadequate endometrial tissue after endometrial sampling were menopausal state, overweight and obese, unemployed, nulliparous, primipara and use of hormonal contraception.

Factors associated with postoperative nausea and vomiting after laparoscopic cholecystectomy at the National Referral Hospital, Bhutan: a cross-sectional study.

INTRODUCTION: Postoperative nausea and vomiting (PONV) are common distressing symptoms experienced after laparoscopic cholecystectomy. We report the rate, and the factors associated with postoperative nausea and vomiting, the patterns of prophylactic antiemetic prescription, and the anesthetic techniques used among patients who underwent laparoscopic cholecystectomy at the Jigme Dorji Wangchuck (JDW) National Referral Hospital, Bhutan. METHODS: A cross-sectional study was conducted at the JDW National Referral Hospital, from January to December 2018. All the patients who underwent laparoscopic cholecystectomy under general anesthesia were included in the study. The demographic variables, premedication, induction agents, muscle relaxants, inhalational agents for maintenance, opioid and adjuvant analgesics, the reversal agents used, and the occurrence of PONV within 24 h were recorded. Data were analyzed using SPSS (version 23). Continuous variables were compared using a t-test or Mann-Whitney test, categorical variables were tested using chi-square or Fisher's exact tests. Binary logistic regression analysis was performed to determine the factors associated with postoperative nausea and vomiting. RESULTS: 190 patients underwent laparoscopic cholecystectomy under general anesthesia. The rate of PONV after laparoscopic cholecystectomy was 31.1% (59/190). Over half (53.7%, 102/190) of the study population were within 21-40 years of age, over 80% (157/190) were female, and 2/3rd were overweight and obese. The most frequently used premedication was ranitidine (39%, 34/87) and metoclopramide (31%, 27/87). More than half (57.4%, 109/190) of the patients received morphine as an opioid analgesic before induction. Sodium thiopentone was a commonly used induction agent (65.8%, 125/190). Succinylcholine and atracurium were mostly preferred muscle relaxants. Isoflurane and air were the most used inhalational anesthetic agents for the maintenance of anesthesia. Ondansetron was the most preferred anti-emetics during the intraoperative period. Previous history of motion sickness (OR 5.8, 95%CI 2.9-11.2, p < 0.001), and use of sodium thiopental (OR 4.1, 95%CI 1.9-9.1, p < 0.001) were independent risk factors for PONV. The use of antiemetics (OR 0.1, 95%CI 0.0-0.4, p = 0.002), propofol (OR 0.2, 95%CI 0.1-0.5, p < 0.001), adjuvant analgesic paracetamol (OR 0.4, 95%CI 0.2-0.8, p = 0.026), and adequate hydration with IV fluids (OR 0.9, 95%CI 0.9-1.0, p = 0.042) were preventive factors for PONV. CONCLUSION: The rate of PONV after laparoscopic cholecystectomy was high. History of motion sickness and use of sodium thiopental for induction were independent risk factors of PONV. The use of multimodal prophylactic antiemetics was robust and superior to monotherapy in preventing PONV. This finding re-emphasizes the need for risk stratification and appropriate use of antiemetics and anesthetic agents to prevent PONV.

Nepali Translation, Validity and Reliability Study of the Cohen-Hoberman Inventory of Physical Symptoms for Utilization With Bhutanese Refugees.

BACKGROUND AND OBJECTIVES: Language-appropriate outcome measurements help to improve health equity. The purpose of this study was to translate and validate the Cohen-Hoberman Inventory of Physical Symptoms (CHIPS) in Nepali for Bhutanese refugee utilization. METHODS: English-Nepali forward and back translations of CHIPS were completed by an official translator and evaluated by three content experts. A scaled rubric measured the following constructs: neurogenic stress response (NSR), somatic stress response (SSR), and visceral stress response (VSR). Data were analyzed using SPSS 26.0. RESULTS: The Nepali version of CHIPS reported good content validity, strong internal consistency (Cronbach's α  = .94), and inter-rater reliability (ICC = 0.91). Kappa statistic reported 88% to 96% agreement. Constructs of NSR (0.91), SSR (0.94), and VSR (0.94) reported strong internal consistency. CONCLUSIONS: The Nepali translated version of CHIPS showed strong validity and reliability for utilization in the Bhutanese refugee population and improves health access to outcome measurements for a vulnerable population.

Modeling the species occurrence probability and response of climate change on Himalayan Somalata plant under different Shared Socioeconomic Pathways.

In this study, the current distribution probability of Ephedra gerardiana (Somalata), a medicinally potent species of the Himalayas, was assessed, and its spatial distribution change was forecasted until the year 2100 under three Shared Socioeconomic Pathways. Here, we used the maximum entropy model (MaxEnt) on 274 spatially filtered occurrence data points accessed from GBIF and other publications, and 19 bioclimatic variables were used as predictors against the probability assessment. The area under the curve, Continuous Boyce Index, True Skill Statistics, and kappa values were used to evaluate and validate the model. It was observed that the SSP5-8.5, a fossil fuel-fed scenario, saw a maximum habitat decline for E. gerardiana driving its niche towards higher altitudes. Nepal Himalayas witnessed a maximum decline in suitable habitat for the species, whereas it gained area in Bhutan. In India, regions of Himachal Pradesh, Uttarakhand, Jammu and Kashmir, and Sikkim saw a maximum negative response to climate change by the year 2100. Mean annual temperature, isothermality, diurnal temperature range, and precipitation seasonality are the most influential variables isolated by the model that contribute in defining the species' habitat. The results provide evidence of the effects of climate change on the distribution of endemic species in the study area under different scenarios of emissions and anthropogenic coupling. Certainly, the area of consideration encompasses several protected areas, which will become more vulnerable to increased variability of climate, and regulating their boundaries might become a necessary step to conserve the regions' biodiversity in the future.

Investigating the interplay between urban dynamics and environmental factors in Thimphu, Bhutan: a satellite remote sensing approach.

The ability of the land surface temperature (LST) and normalized difference vegetation index (NDVI) to examine land surface change is regarded as an important climate variable. However, no significant systematic examination of urbanization concerning environmental variables has been undertaken in the narrow valley of Thimphu, Bhutan. Therefore, this study investigated the impact of land use/land cover (LULC) dynamics on LST, NDVI, and elevation, using Moderate Resolution Imaging Spectroradiometer (MODIS) data collected in Thimphu, Bhutan, from 2000 to 2020. The results showed that LSTs varied substantially among different land use types, with the highest occurring in built-up areas and the lowest occurring in forests. There was a strong negative linear correlation between the LST and NDVI in built-up areas, indicating the impact of anthropogenic activities. Moreover, elevation had a noticeable effect on the LST and NDVI, which exhibited very strong opposite patterns at lower elevations. In summary, LULC dynamics significantly influence LST and NDVI, highlighting the importance of understanding spatiotemporal patterns and their effects on ecological processes for effective land management and environmental conservation. Moreover, this study also demonstrated the applicability of relatively low-cost, moderate spatial resolution satellite imagery for examining the impact of urban development on the urban environment in Thimphu city.

Local or regional flaps in developing country: Experience from Eastern Bhutan.

Soft tissue reconstruction plays an integral part in orthopaedic surgery. For developing country like Bhutan, where no micro-surgical or plastic surgeons are available, orthopaedic surgeons perform the local or regional flaps for the soft tissue defects. In this paper, we describe the use of different kinds of local and regional flaps and its outcome at Eastern Regional Referral Hospital, Bhutan.

Conceptualisations of pain amongst resettled Nepali-speaking Bhutanese adults in rural and regional Australia.

INTRODUCTION: Nepali-speaking Bhutanese refugees have been subject to one of the largest resettlement programs in the world and experience higher rates of chronic pain when compared to the general population. The purpose of this study was to explore qualitative conceptualisations of chronic pain among a group of Nepali-speaking Bhutanese adults with a refugee background who relocated to rural and regional Australia. METHODS: Participants included 22 individuals (females n=15) with chronic pain, who took part in structured qualitative focus groups exploring their experiences of chronic pain. Data were analysed using thematic analysis and five main themes were developed. RESULTS: The themes were: (1) pain is persistent and creates suffering, (2) pain is subjective and poorly understood, (3) pain is a biomedical problem that needs to be solved, (4) pain is complex and more than a biomedical problem, and (5) coping with pain is multi-faceted.Some participants viewed pain through a predominantly biomedical lens, and some recognised social and psychological factors as contributors to pain. Overwhelmingly, the participants believed pain is complex and multifaceted, requiring active and passive strategies for management, some of which are culturally informed. CONCLUSION: The experiences of resettled Nepali-speaking Bhutanese refugees living with pain are important to elucidate to improve healthcare inequalities among this marginalised group. This research will inform future assessment guidelines and treatment programs for Nepali-speaking Bhutanese adults living with chronic pain.

Environmental, Occupational, and Demographic Risk Factors for Clinical Scrub Typhus, Bhutan.

Underdiagnosis and underreporting of scrub typhus has increasingly affected public health in Bhutan since its initial detection in 2008. Identifying scrub typhus risk factors would support early diagnosis and treatment for this nonspecific febrile disease, reducing the incidence of potentially fatal complications. We conducted a hospital-based, case‒control study during October‒December 2015 in 11 scrub typhus‒prone districts. We identified harvesting cardamom as the major risk factor (odds ratio 1,519; p<0.001); other factors were traditional housing, largely caused by an outside toilet location, as well as owning a goat and frequently sitting on grass. Harvesting vegetables, herding cattle in the forest, and female sex were protective. Age had a nonlinear effect; children and the elderly were more likely to seek treatment for clinical scrub typhus. This study has informed public health policies and awareness programs for healthcare workers through development of National Guidelines for Prevention, Treatment and Control of Scrub Typhus in Bhutan.

An exploratory study on the perceptions of rabies and ill-health causations and health seeking behaviours of school children and local communities in southern Bhutan.

BACKGROUND: The perception of illness and health-seeking behaviours, including rabies differ from one culture to another. Depending on the cultural setting of the society in which people live, the definition of the causal factors of illness may range from natural biological causes to supernational causes which greatly influence subsequent health-seeking behaviour. To ensure best health practices and plan effective health interventions for the control of dog-mediated-human rabies, we explored how school children and adult communities perceive and respond to illnesses, including rabies in southern Bhutan. METHODS: We collected quantitative data related to the causes of illness and health-seeking practices of school children using a questionnaire survey (QS). Qualitative data were collected through focus group discussions (FGDs) and in-depth interviews (IDIs) with older members of communities (≥ 18 years) that work closely with school children. Descriptive analysis was performed for the quantitative data and thematic analysis was performed for the qualitative data. RESULTS: The participants during the FDGsand IDIshave linked the illnesses to past actions, spirits, energy channels, planetary movement, sorcery, black magic, food, physical or environmental factors, individual habits and social factors. The survey of the school children reported microorganisms (75%), past actions (16.8%), spirits (9.6%) and black magic (9.1%) as causal factors for illnesses. Health seeking behaviours reported by the participants included visiting hospitals, performing spiritual or religious rituals and local treatments. Similarly, school children also mentioned that illnesses can be treated by visiting hospitals (98%), performing rituals (59.1%), and seeking traditional treatments practices (18.8%). Both school children and adult members of the communities that we interviewed were well aware on the causes of rabies and need for allopathic treatments rather than seeking spiritual or local treatments. CONCLUSION: There is a need for the consideration of the socio-cultural context in the planning and implementation of health-related policies, including the rabies prevention programs in Bhutan, by involving traditional healers and religious entities with "One Health" public health sectors.

Healthcare in the Himalayan Kingdom of Bhutan: Lessons for the United States and other western healthcare systems.

Bhutan has demonstrated a trajectory of advances in healthcare, while still remaining true to its culture and traditional forms of medicine. Most recently, Bhutan gained international attention when it implemented a strategic Covid-19 vaccination programme that protected a greater percentage of its population than observed in Western industrialised nations. This accomplishment supports the idea that there are lessons from Bhutan to be shared with the rest of the world. In this work, we delineate our observations of the Bhutanese healthcare system, based on field observations in several Bhutanese cities, and results from surveys of Bhutanese physicians. We identify a number of unique practices that influence patient compliance, health education, and access to care in the Bhutanese system, that may be of particular interest and applicability to other healthcare systems. These include housing multiple health services at one location, fully funded medical visits, using non-physician teachers for health education and use of Gross National Happiness (GNH) measures in care.

Malaria outbreak along the India-Bhutan border town of Saralpara, Assam, India.

BACKGROUND & OBJECTIVES: A remarkable progress is being made in the South-East Asia region in reducing the burden of malaria. While all countries are committed to malaria elimination, continued transmission at and across international borders poses a threat to achieving this goal. METHODS: We investigated an outbreak of malaria in the India-Bhutan border area in a district of Assam state, India. A line listing of cases occurring during the outbreak period was made and a house-to-house survey was carried out to identify additional cases in the community. Entomological investigation consisted of light trap collection of vectors. Patients and health workers were interviewed to obtain information on the possible mode of transmission and ongoing inter-country collaboration across the border. RESULTS: Between October 21 to November 18 2022, 37 cases of malaria (all Plasmodium vivax), were diagnosed in Saralpara area of Kokrajhar district of Assam, bordering Bhutan. Of these four were diagnosed in Sarpang hospital, Bhutan. Median age was 20 years (range 3 to 70 years). Male to female ratio was 1:1.2. In addition, 6 individuals with asymptomatic malaria were detected in the community through an active case finding campaign. No cases were however reported on Bhutan side of the border. Anopheles culicifacies and An. annularis were identified from light trap collection. Saralpara is a remote and forested area where most of the residents are poor and engaged predominantly in farming activities. Being a harvesting season, they tend to stay overnight to protect their harvest from elephants. The health authorities in India and Bhutan exchanged information regularly at district-to-district level on the outbreak including through available and easy modes such as WhatsApp, telephone as well as electronic mail and collaborated in coherently implementing preventive measures on both sides and in managing the cases. INTERPRETATION & CONCLUSION: The outbreak of malaria in Saralpara demonstrates the risk of malaria outbreak in remote and forested areas, with possibility of spill over to the other side of the border. The fact that two countries had excellent inter-country cross-border collaboration and prior commitment thereby preventing further transmission of malaria to Bhutan can serve as a best practice for cross-border control of malaria and other communicable diseases.

What factors affect the ability of refugees to access dental care services?

DESIGN: This was a systematic review of the quantitative evidence for which factors influence the ability of refugee populations to access dental care services. DATA SOURCES: Searches were performed using broad search terms on the electronic databases MEDLINE (via Ovid), Embase (via Ovid), Web of Science (all databases) and American Psychology Association PsycINFO with no time, language, or regional restrictions. STUDY SELECTION: Studies examining factors associated with access to dental care amongst refugees were eligible. Outcomes relating to any aspect of access were included. Quantitative observational or intervention studies including quantitative components of mixed method studies, were eligible for inclusion. Studies not published in English were excluded. DATA EXTRACTION AND SYNTHESIS: Data extraction was performed by a single author, with a random sample of 10% reviewed by a second. Quality was assessed utilising the National institute for Health's Quality Assurance tool for observational studies and were identified as being either fair (n = 7) or poor (n = 2). Factors identified as influencing access were synthesised using the Behavioural Model of Health Services Use. RESULTS: In total, 69 full-text articles were screened. Nine were included in the final narrative synthesis, including refugee populations across 10 countries (5 individual countries and one including multiple countries). Designs were cross sectional (n = 6) or retrospective (n = 3). Different populations were investigated, including children (n = 4) and adults (n = 5). Refugee populations included Somali (n = 2), Tibetan (n = 1), Palestinian (n = 1), Bhutanese (n = 1), Burmese (n = 1) and mixed groups (n = 4). Common measurements of access included self-reported past dental visits (n = 5), use of dental services (n = 1), perceived barriers to access (n = 1) and missed appointments (n = 1). Untreated decay was used as a proxy measure (n = 1). Common factors identified influencing access related to demography, socio-economic status, acculturation, health and dental literacy and oral health status of refugees. At an individual level, English language proficiency was associated with increased access to dental care. CONCLUSIONS: There is limited evidence on the effects of various factors on influencing access to dental services for refugees. The authors suggest that on an individual level, English language proficiency, acculturation, health and dental literacy and oral health status of refugees may influence access to dental services.

High quality social environment buffers infants' cognitive development from poor maternal mental health: Evidence from a study in Bhutan.

Poor maternal mental health negatively impacts cognitive development from infancy to childhood, affecting both behavior and brain architecture. In a non-western context (Thimphu, Bhutan), we demonstrate that culturally-moderated factors such as family, community social support, and enrichment may buffer and scaffold the development of infant cognition when maternal mental health is poor. We used eye-tracking to measure early building blocks of cognition: attention regulation and social perception, in 9-month-old Bhutanese infants (N = 121). The cognitive development of Bhutanese infants in richer social environments was buffered from poor maternal mental health, while for infants in environments with lower rates of protective social environment factors, worse maternal mental health significantly predicted greater costs for infant attention, a fundamental building block cognition. International policies and interventions geared to improve maternal mental health and child health outcomes should incorporate each regions' unique family, cultural, and community support structures.

Biomonitoring of per- and polyfluoroalkyl substances in minority angler communities in central New York State.

Onondaga Lake in central New York State was listed as a Superfund site in 1994 due to industrial disposal of pollutants. A biomonitoring program was conducted to assess exposure to over 70 legacy contaminants and contaminants of emerging concern in populations disproportionately at risk for exposure residing near Onondaga Lake and to educate these communities on how to reduce exposures. The populations of focus were refugees from Burma and Bhutan and low-income, primarily African American, anglers (urban anglers). These communities consume locally caught fish for economic as well as cultural reasons and therefore may be at higher risk of exposure. This study focuses on assessment of exposure to per- and polyfluoroalkyl substances (PFAS) and associations with local fish consumption. Using respondent driven sampling, 311 refugees and 89 urban anglers were enrolled in the study. Following informed consent, study participants provided blood and urine specimens and completed a questionnaire. Percentiles of locally caught fish meals in the past 12 months by race/ethnicity groups showed that the Burmese participants of Karen ethnicity were the highest consumers, with a median of 135 meals compared to 103 meals for the other Burmese participants, 70 meals for the urban anglers, and 44 meals for the Bhutanese participants. Compared to the National Health and Nutrition Examination Survey (NHANES) 2015-16 sample of the general U.S. population, the Karen participants had markedly elevated perfluorooctane sulfonic acid (PFOS) and perfluorodecanoic acid (PFDA) levels with median serum concentrations 9.5 times greater (41.6 ng/mL vs. 4.4 ng/mL) and 26.9 times greater (2.69 ng/mL vs. 0.10 ng/mL), respectively; the other Burmese participants had moderately elevated levels of PFOS and PFDA with median serum concentrations 3.0 times greater (13.3 ng/mL vs. 4.4 ng/mL) and 7.3 greater times greater (0.73 ng/mL vs. 0.10 ng/mL), respectively; and, PFAS levels were not elevated in the Bhutanese or urban angler cohorts. Male gender was consistently the strongest predictor of PFAS exposure among all study cohorts. A positive association between local fish consumption was indicated only for PFOS among urban anglers. An association between local fish consumption and PFAS was not statistically significant among the refugee cohorts, perhaps due to the lack of 'lower-end' exposure or exposure variability. Community events were held by the program staff to present the biomonitoring results and distribute community outreach materials with visual aids specific for the study populations to promote safe fish eating.

The effect of spanking on early social-emotional skills.

Whether spanking is detrimental for social-emotional (SE) development remains controversial, mostly due to disputes around the internal and external validity of existing evidence. This study examined the effect of spanking on the SE development of Bhutanese children, using a national, longitudinal sample (N = 1377; Mage  = 50.5 months old; 50% girls). Following best-practice recommendations for mitigating issues of selection bias in observational developmental research, the study employed conservative methods (i.e., child fixed-effects and lagged-dependent variables) and robustness checks to assess the internal validity of estimates. Across approaches, spanking predicted reductions in SE skills of .09-.17 SD, even after controlling for all time-invariant confounders and baseline levels of SE skills. These findings strengthen the argument that spanking might be harmful to young children's SE development.

Severity of age-related macular degeneration at first presentation in Bhutan: a 3-year national study.

BACKGROUND: Medical services are still developing in Bhutan. There is no published national report on age-related macular degeneration (AMD). We therefore aim to determine the demographic characteristics and severity of AMD at first presentation among Bhutanese patients attending their recently inaugurated vitreoretinal (VR) clinics over a 3-year national survey, and to inform national health policy to develop suitable health program to prevent AMD-related blindness and visual impairment. METHODS: A retrospective cross-sectional consecutive case series study was conducted on all new AMD cases in Bhutan. If a patient presented with asymmetrical AMD, the eye with more severe AMD was considered. If both the eyes had the same severity one eye was chosen randomly. Collection of demographic data and clinical details including diagnostic testing (fundus photography, OCT and fluorescent angiography) and clinical staging were performed. RESULTS: Of 521 new AMD patients aged 71.9 ± 11.3 years, 306/521 (58.7%) were males (p = 0.005). At their first presentation, 234/521 patients (44.9%) already had late-stage AMD. Importantly, 69/234 patients (29.5%), that is half of total neovascular AMD (nAMD) patients, had disciform scars (DS) which were beyond treatment, and 7/234 patients (3.0%) had geographic atrophy (GA). Seven patients had retinal pigment epithelium tear at presentation. Fourteen of nineteen polypoidal choroidal vasculopathy (PCV) patients were younger than 50 years. CONCLUSIONS: Half of nAMD cases presented as DS not amenable to the treatment. Many potentially treatable nAMD patients had already lost central vision and were legally blind. Young people with PCV losing vision early in life with longer morbidity-affected life and socio-economic burden was concerning. GA and DS cases need visual rehabilitation to improve their QoL. Incorporating a screening program for AMD with effective health education, and maintaining a national AMD Registry, would potentially lower AMD-related blindness and visual impairment.
