    We present a new method, Fine-Mapping of Adaptive Variation (FineMAV), which combines population differentiation, derived allele frequency, and molecular functionality to prioritize positively selected candidate variants for functional follow-up. We calibrate and test FineMAV using eight experimentally validated "gold standard" positively selected variants and simulations. FineMAV has good sensitivity and a low false discovery rate. Applying FineMAV to the 1000 Genomes Project Phase 3 SNP dataset, we report many novel selected variants, including ones in TGM3 and PRSS53 associated with hair phenotypes that we validate using available independent data. FineMAV is widely applicable to sequence data from both human and other species.

    BACKGROUND: Most tuberculosis (TB) disease in the United States (US) is attributed to reactivation of remotely acquired latent TB infection (LTBI) in non-US-born persons who were likely infected with Mycobacterium tuberculosis in their countries of birth. Information on LTBI prevalence by country of birth could help guide local providers and health departments to scale up the LTBI screening and preventive treatment needed to advance progress toward TB elimination.

    METHODS: A total of 13 805 non-US-born persons at high risk of TB infection or progression to TB disease were screened for LTBI at 16 clinical sites located across the United States with a tuberculin skin test, QuantiFERON Gold In-Tube test, and T-SPOT.TB test. Bayesian latent class analysis was applied to test results to estimate LTBI prevalence and associated credible intervals (CrIs) for each country or world region of birth.

    RESULTS: Among the study population, the estimated LTBI prevalence was 31% (95% CrI, 26%-35%). Country-of-birth-level LTBI prevalence estimates were highest for persons born in Haiti, Peru, Somalia, Ethiopia, Vietnam, and Bhutan, ranging from 42% to 55%. LTBI prevalence estimates were lowest for persons born in Colombia, Malaysia, and Thailand, ranging from 8% to 13%.

    CONCLUSIONS: LTBI prevalence in persons born outside the US varies widely by country. These estimates can help target community outreach efforts to the highest-risk groups.

    OBJECTIVES: To evaluate, among the elderly, the association of self-rated health (SRH) with mortality, and to identify determinants of self-rating health as "at-least-good".

    STUDY DESIGN: Individual data on SRH and important covariates were obtained for 424,791 European and United States residents, ≥60 years at recruitment (1982-2008), in eight prospective studies in the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES). In each study, adjusted mortality ratios (hazard ratios, HRs) in relation to SRH were calculated and subsequently combined with random-effect meta-analyses.

    MAIN OUTCOME MEASURES: All-cause, cardiovascular and cancer mortality.

    RESULTS: Within the median 12.5 years of follow-up, 93,014 (22%) deaths occurred. SRH "fair" or "poor" vs. "at-least-good" was associated with increased mortality: HRs 1.46 (95% CI 1·23-1.74) and 2.31 (1.79-2.99), respectively. These associations were evident: for cardiovascular and, to a lesser extent, cancer mortality, and within-study, within-subgroup analyses. Accounting for lifestyle, sociodemographic, somatometric factors and, subsequently, for medical history explained only a modest amount of the unadjusted associations. Factors favourably associated with SRH were: sex (males), age (younger-old), education (high), marital status (married/cohabiting), physical activity (active), body mass index (non-obese), alcohol consumption (low to moderate) and previous morbidity (absence).

    CONCLUSION: SRH provides a quick and simple tool for assessing health and identifying groups of elders at risk of early mortality that may be useful also in clinical settings. Modifying determinants of favourably rating health, e.g. by increasing physical activity and/or by eliminating obesity, may be important for older adults to "feel healthy" and "be healthy".

    BACKGROUND: Polyhydroxyalkanoates are bio-based, biodegradable naturally occurring polymers produced by a wide range of organisms, from bacteria to higher mammals. The properties and biocompatibility of PHA make it possible for a wide spectrum of applications. In this context, we analyze the potential applications of PHA in biomedical science by exploring the global trend through the patent survey. The survey suggests that PHA is an attractive candidate in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packaging material as well as other useful products.

    OBJECTIVE: In our present study, we explored patents associated with various biomedical applications of polyhydroxyalkanoates.

    METHOD: Patent databases of European Patent Office, United States Patent and Trademark Office and World Intellectual Property Organization were mined. We developed an intensive exploration approach to eliminate overlapping patents and sort out significant patents.We demarcated the keywords and search criterions and established search patterns for the database request. We retrieved documents within the recent 6 years, 2010 to 2016 and sort out the collected data stepwise to gather the most appropriate documents in patent families for further scrutiny.

    RESULTS: By this approach, we retrieved 23,368 patent documents from all the three databases and the patent titles were further analyzed for the relevance of polyhydroxyalkanoates in biomedical applications. This ensued in the documentation of approximately 226 significant patents associated with biomedical applications of polyhydroxyalkanoates and the information was classified into six major groups. Polyhydroxyalkanoates has been patented in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packagingmaterial as well as other useful products.

    CONCLUSION: There are many avenues through which PHA & PHB could be used. Our analysis shows patent information can be used to identify various applications of PHA and its representatives in the biomedical field. Upcoming studies can focus on the application of PHA in the different field to discover the related topics and associate to this study.We believe that this approach of analysis and findings can initiate new researchers to undertake similar kind of studies in their represented field to fill the gap between the patent articles and research publications.

    Background. Central intermediary metabolism (CIM) in bacteria is defined as a set of metabolic biochemical reactions within a cell, which is essential for the cell to survive in response to environmental perturbations. The genes associated with CIM are commonly found in both pathogenic and non-pathogenic strains. As these genes are involved in vital metabolic processes of bacteria, we explored the efficiency of the genes in genotypic characterization of Burkholderia pseudomallei isolates, compared with the established pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) schemes. Methods. Nine previously sequenced B. pseudomallei isolates from Malaysia were characterized by PFGE, MLST and CIM genes. The isolates were later compared to the other 39 B. pseudomallei strains, retrieved from GenBank using both MLST and sequence analysis of CIM genes. UniFrac and hierachical clustering analyses were performed using the results generated by both MLST and sequence analysis of CIM genes. Results. Genetic relatedness of nine Malaysian B. pseudomallei isolates and the other 39 strains was investigated. The nine Malaysian isolates were subtyped into six PFGE profiles, four MLST profiles and five sequence types based on CIM genes alignment. All methods demonstrated the clonality of OB and CB as well as CMS and THE. However, PFGE showed less than 70% similarity between a pair of morphology variants, OS and OB. In contrast, OS was identical to the soil isolate, MARAN. To have a better understanding of the genetic diversity of B. pseudomallei worldwide, we further aligned the sequences of genes used in MLST and genes associated with CIM for the nine Malaysian isolates and 39 B. pseudomallei strains from NCBI database. Overall, based on the CIM genes, the strains were subtyped into 33 profiles where majority of the strains from Asian countries were clustered together. On the other hand, MLST resolved the isolates into 31 profiles which formed three clusters. Hierarchical clustering using UniFrac distance suggested that the isolates from Australia were genetically distinct from the Asian isolates. Nevertheless, statistical significant differences were detected between isolates from Malaysia, Thailand and Australia. Discussion. Overall, PFGE showed higher discriminative power in clustering the nine Malaysian B. pseudomallei isolates and indicated its suitability for localized epidemiological study. Compared to MLST, CIM genes showed higher resolution in distinguishing those non-related strains and better clustering of strains from different geographical regions. A closer genetic relatedness of Malaysian isolates with all Asian strains in comparison to Australian strains was observed. This finding was supported by UniFrac analysis which resulted in geographical segregation between Australia and the Asian countries.

    OBJECTIVES: The COVID-19 pandemic has impacted the mental health of people worldwide. Psychological resilience has been shown to buffer against the threat of the pandemic (i.e., COVID-19 fear) and sustain mental health. The extent to which psychological resilience factors impact mental health maintenance, however, is unclear, given broad differences in infection rates, prevention approaches, government interventions across different cultures and contexts. Our study examines resilience factors and how they protect individuals from COVID-19-related fear and sustain their mental health.

    DATA DESCRIPTION: Data were collected from 1583 (Mage = 32.22, SD = 12.90, Range = 19-82) respondents from Japan, China, the United States, and Malaysia between October to November 2020. We collected data across age and sex, marital status, number of children, and occupations. We also accounted for stay-at-home measures, change in income, COVID-19 infection status, place of residence, and subjective social status in the study. Our variables included mental health-related and resilience constructs, namely (i) fear of COVID-19, (ii) depression, anxiety, and stress; (iii) present, past, and future life satisfaction, (iv) sense of control, (v) positive emotions, (vi) ego-resilience, (vii) grit, (viii) self-compassion, (ix) passion, and (x) relational mobility. All questionnaires were assessed for their suitability across the four countries with the necessary translation checks. Results from this study can be instrumental in examining the impact of multiple resilience factors and their interaction with demographic variables in shaping mental health outcomes.

    Illicit drugs are used to produce a sense of euphoria in the user. Like marijuana, kratom is a plant-based substance. The leaves of the Mitragyna speciosa tree were used to treat mild medical conditions in Thailand and Malaysia as a stimulant in low doses, and sedative and analgesic at high doses. Over recent years, kratom gained popularity as a recreational drug among younger individuals in Southeast Asia due to its availability as a cheap and easily assessable substance with euphoric effects. This trend has rapidly made its way to the West. Unlike marijuana, in the United States kratom's use as an inexpensive herbal recreational "supplement" is poorly popularized. However, emerging reports garnished from use as a recreational drug reveals a potential health hazard. Seizures and neurological consequences have been reported from kratom abuse. Complex pharmacokinetics place patients at further risk of side effects and drug interactions. Still, individuals can legally purchase kratom at stores and through online distributers in capsule form or as teas, powders, and extracts under the veil of a harmless herbal remedy. Without United States Food and Drug Administration oversight, kratom has a high potential for abuse and without regulatory control threatens public safety.

    There is a strong need to reduce costs of hospital and advocating health economics in countries like the United States of America. The rising cost of healthcare globally especially in the United States of America has interestingly outraged the temper of many citizens about the Obamacare and Trumpcare. The issue about high cost in healthcare is the failure for people globally to recognize that healthcare facility is a 24-hour round-the-clock service. It therefore involves doubling of the utility bills, tripling the manpower due to shifts and rest, wear-and-tear of basic electrical devices is short-lived, breakdown period of huge machine is consistently due to overloaded usages in the government hospitals and poor knowledge of the maintenance programme. Low birth weights (LBW) is a public health concern because it has a well-known predisposition to increased risk for perinatal infections, respiratory distress and ultimately mortality. There is also a higher risk of poor health outcomes throughout the life course of the LBW newborns that includes Type 2 diabetes, high blood pressure, neurodevelopmental disabilities and cardiovascular diseases. The World Health Organization and United Nations Child’s Fund estimate the prevalence of low birth weights in the world ranges from 3% to 32%. Albania in the year 2000 recorded prevalence of low birth weight of 3% whereas Yemen recorded a low birth weight of 32% in 1997. In 2015, the US national vital statistics pointed out that 83.9% of preterm birth (PTB) are LBW. This indicates that prevention of PTB will lead to a decrease in the incidence of LBW.

    PURPOSE: International studies document that lesbian, gay, bisexual, transgender, queer and intersex (LGBTQI+) patients face significant health disparities. Studies exploring the attitudes, knowledge, preparedness and comfort levels of healthcare students towards LGBTQI+ health have been conducted in the United States, United Kingdom and Malaysia. This study aims to investigate stigma in healthcare for LGBTQI+ patients in Singapore, and possible upstream factors within medical education.

    METHODS: This mixed-methods study adopts a convergent parallel design. The Health Stigma and Discrimination Framework was referenced to devise in-depth interviews with representatives from 13 LGBTQI-affirming non-governmental organisations, analysed through thematic analysis. 320 clinical medical students were surveyed about attitudes, knowledge, comfort, preparedness, and perceived importance of/towards LGBTQI+ health, analysed via descriptive statistics and multivariate regression.

    RESULTS: Prevailing stigma in Singaporean society against LGBTQI+ individuals is exacerbated in healthcare settings. Doctors were cited as unfamiliar or uncomfortable with LGBTQI+ health, possibly from lack of training. Among medical students surveyed, the median composite attitudes, comfort and preparedness index was 3.30 (Interquartile Range (IQR) = 0.50), 3.17 (IQR = 0.83), 2.50 (IQR = 1.00) respectively. Only 12.19% of students answered all 11 true-false questions about LGBTQI+ health correctly.

    CONCLUSION: Medical students in Singapore have scored sub-optimally in their knowledge and preparedness towards LGBTQI+ health, while interpersonal and structural stigma in healthcare towards LGBTQI+ people in Singapore negatively affects health and wellbeing. These findings are an impetus to improve medical training in this area. High scores among medical students in attitudes, comfort and perceived importance of LGBTQI+ topics demonstrate that there is space for LGBTQI+ health in the local medical education curriculum. Curricular interventions can prioritise content knowledge, communication skills and sensitivity.

    BACKGROUND: Acne vulgaris is a common chronic disease, and evidence-based clinical practice guidelines (CPGs) can provide credible treatment information.

    METHOD: A literature search for acne CPGs published between January 2008 and September 2013 was conducted. Two reviewers independently applied the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. METHODological quality was evaluated by ranking in AGREE II domains and the highest number of items scoring above the neutral threshold score.

    RESULTS: Four CPGs fulfilled the selection criteria, and the highest ranked were the European and Malaysian. Highest scores achieved by the former were for scope/purpose, stakeholder involvement, and rigor of development and by the latter were for scope/purpose, clarity of presentation, and applicability. Applicability was the lowest scoring of all domains for all CPGs.

    CONCLUSION: European and Malaysian acne CPGs were ranked highest for methodological quality and may serve to inform clinical practice and guideline adaptation.

    Three authors describe problematic scenarios of health policy in their respective countries. These examples illustrate the role of government influences in determining resource allocation, legislation, health provision and health outcomes in very different situations. These outcomes are affected not only by attitudes to public health, but also by the legal systems in the countries which are the subjects of this study. The authors draw conclusions about the use and abuse of public health regulation.

    The focus of this paper will be on how health care systems in three countries, Malaysia, South Africa and the United States, are responding to the health needs of immigrants with a strong focus on the legal aspects of the respective national responses. The Malaysia portion emphasizes legal immigration and analyses as to how the country's Ministry of Health and the delivery system itself is responding to the demands of immigrant's health. In the context of South Africa, the paper explores implications of the South African Constitution, which establishes a right to access health care, and explores whether such a right can be extended to non-citizens, or can be tempered by economic constraints. In the American discussion the focus is on whether publicly supported health care programs can be accessed to provide coverage for undocumented residents, and highlights recent constraints in using government monies in this area.

    The blood of the Painted Storks (Mycteria leucocephala) and the Milky Storks (M. cinerea) from Malaysia were collected
    invasively from the breeding site. The blood was dropped on to FTA® cards and stored at room temperature. DNA was isolated from
    the FTA® cards through a modification of the Wizard DNA Purification kit (Promega) procedure and PCR was performed with 11 pairs
    of microsatellite primers of the American Wood Stork (M. americana). The collection of a drop of blood onto the card is superior to the
    usual practice of collecting about five ml of blood into a vacuum tube as it causes fewer traumas to these sensitive birds. Moreover, this
    collection procedure can be adopted for use in various wild animal species which are usually found in the remote areas of Malaysia as
    the sample collection cards can be transported back to the laboratory at room temperature. Our procedure allows the typing of several
    molecular genetic markers from just a drop of blood collected in the field and stored at room temperature alleviating the need for storage
    in expensive deep freezers or liquid nitrogen tanks.

    Every woman experiences the menopause transition period in a very individual way. Menopause symptoms and management are greatly influenced by socioeconomic status in addition to genetic background and medical history. Because of their very unique cultural heritage and often holistic view of health and well-being, menopause symptoms and management might differ greatly in aboriginals compared to non-aboriginals. Our aim was to investigate the extent and scope of the current literature in describing the menopause experience of aboriginal women. Our systematic literature review included nine health-related databases using the keywords 'menopause' and 'climacteric symptoms' in combination with various keywords describing aboriginal populations. Data were collected from selected articles and descriptive analysis was applied. Twenty-eight relevant articles were included in our analysis. These articles represent data from 12 countries and aboriginal groups from at least eight distinctive geographical regions. Knowledge of menopause and symptom experience vary greatly among study groups. The average age of menopause onset appears earlier in most aboriginal groups, often attributed to malnutrition and a harsher lifestyle. This literature review highlights a need for further research of the menopause transition period among aboriginal women to fully explore understanding and treatment of menopause symptoms and ultimately advance an important dialogue about women's health care.

    The Broad Conceptualization of Beauty Scale (BCBS) assesses the degree to which women perceive diverse appearances and internal qualities as being beautiful. Although the instrument is increasingly used in diverse national and linguistic contexts, no previous study has examined measurement invariance of the BCBS across racial groups. To rectify this, we asked 395 Black, 406 Hispanic, and 423 White women from the United States to complete the BCBS. Confirmatory factor analysis indicated that a unidimensional model of BCBS scores had poor fit to the data in the total sample, but freely estimating error covariances between six pairs of items resulted in adequate fit. Additionally, full configural and scalar invariance was supported, but metric invariance was not, with further testing indicating that the item loading for one item differed across groups. Comparison of latent means indicated that all between-groups comparisons in BCBS scores were non-significant. However, medium-sized group differences in BCBS scores emerged once group differences in key demographics were controlled for. Overall, these results suggest that the BCBS largely achieves measurement invariance across Black, Hispanic, and White women in the United States, suggestive of similarity in how the construct of broad conceptualisation of beauty is understood and experienced.
