    PURPOSE: This study investigated if Rohingya refugee people resettled in camps in rural Bangladesh and urban locations in Malaysia had different levels of trauma, mental health and everyday functioning. The study also examined if direct and indirect exposure to traumatic events could predict PTSD, depression, generalized anxiety, and everyday functioning in the two groups separately. An attempt was also made to see if the relations between trauma and mental health were different across the two settings.

    METHODS: This was a cross-sectional study, for which we conveniently recruited 100 adult Rohingyas, 50 from each country; the majority was males. Rohingyas in Bangladesh fled Myanmar's Rakhine State following a major military crackdown in 2017, whereas Rohingyas in Malaysia fled Rakhine gradually over the last three decades because of recurrent violence and military operations. We assessed trauma (cumulative trauma, direct trauma, and indirect trauma), PTSD, depression, generalized anxiety, and everyday functioning of the participants using traumatic event questionnaire, PTSD-8, PHQ-9, GAD-7, and WHODAS-2.0.

    RESULTS: The Bangladeshi cohort experienced more types of traumatic events (i.e., cumulative trauma) than did the Malaysian cohort (d = 0.58). Although the two cohorts did not differ in terms of indirect exposure to traumatic incidents (i.e., indirect trauma), the Malaysian cohort had direct exposure to traumatic events (i.e., direct trauma) more frequently than did the Bangladeshi cohort (d = 1.22). The Bangladeshi cohort showed higher PTSD (d = 1.67), depression (d = 0.81), generalized anxiety (d = 1.49), and functional impairment (d = 2.51) than those in Malaysia. Hierarchical linear regression analyses showed that after controlling for demographic variables, both direct and indirect trauma significantly predicted PTSD, depression, and functional impairment among Rohingyas in Bangladesh, with direct trauma being the stronger predictor. However, similar analyses showed that only indirect trauma predicted PTSD among Rohingyas in Malaysia, while all other effects were nonsignificant. The results also showed that the predictive relationship between direct trauma and PTSD was different across the two countries. With the same level of direct trauma, a participant from Malaysia would score 0.256 points lower in PTSD than a participant from Bangladesh.

    CONCLUSION: The recently experienced direct and indirect trauma have impaired mental health and everyday functioning among the Bangladeshi cohort. However, only indirect trauma was active to cause PTSD in the Malaysian cohort as direct trauma was weakening due to the time elapsed since migration. We discuss the results in the context of the current theories of trauma and mental health and suggest therapeutic interventions for the refugee population.

    Background: Although glue sniffing has been linked with significant morbidity and mortality, it is still under-researched and poorly recognized issue globally. Objective: A scoping review was performed to identify the factors and outcomes related to glue sniffing in India, Pakistan, Nepal and Bangladesh. Methods: Ten databases; Medline via Ovid, Google scholar, EBSCOhost (CINAHL Plus), ProQuest Central, PsycInfo, IndMED, Ovid Embase, Scopus, PubMed, and Science Direct were searched from their inception to January 2019 for both qualitative and quantitative studies examining any aspect of glue-sniffing. Studies published only in English language were included. Prevalence of glue-sniffing in SAARC region was the primary outcome measure. Findings: Of 8951studies screened, 344 were assessed for eligibility and 31 studies were included. The majority of the studies were conducted in India (15) and Pakistan (11). Meta-analysis of proportion, using random effects model, for both primary and secondary outcomes found that the highest incidence of glue sniffing was 57% (0.57, CI 95% 0.49-0.66) in India. The overall incidence of tobacco and naswar (snuff) as was 83% (0.83, 95% CI 0.80-0.86). Conclusions: The prevalence of glue sniffing, especially among street children, is alarmingly high and presents a challenge for health and social services for countries in SAARC region. More research work is required to examine long term impact of glue sniffing on physical and mental health.

    BACKGROUND: Small-quantity lipid-based nutrient supplements (SQ-LNSs) have been shown to reduce the prevalence of child anemia and iron deficiency, but effects on other micronutrients are less well known. Identifying subgroups who benefit most from SQ-LNSs could support improved program design.

    OBJECTIVES: We aimed to identify study-level and individual-level modifiers of the effect of SQ-LNSs on child hemoglobin (Hb), anemia, and inflammation-adjusted micronutrient status outcomes.

    METHODS: We conducted a 2-stage meta-analysis of individual participant data from 13 randomized controlled trials of SQ-LNSs provided to children 6-24 mo of age (n = 15,946). We generated study-specific and subgroup estimates of SQ-LNSs compared with control, and pooled the estimates using fixed-effects models. We used random-effects meta-regression to examine potential study-level effect modifiers.

    RESULTS: SQ-LNS provision decreased the prevalence of anemia (Hb < 110 g/L) by 16% (relative reduction), iron deficiency (plasma ferritin < 12 µg/L) by 56%, and iron deficiency anemia (IDA; Hb < 110 g/L and plasma ferritin <12 µg/L) by 64%. We observed positive effects of SQ-LNSs on hematological and iron status outcomes within all subgroups of the study- and individual-level effect modifiers, but effects were larger in certain subgroups. For example, effects of SQ-LNSs on anemia and iron status were greater in trials that provided SQ-LNSs for >12 mo and provided 9 (as opposed to <9) mg Fe/d, and among later-born (than among first-born) children. There was no effect of SQ-LNSs on plasma zinc or retinol, but there was a 7% increase in plasma retinol-binding protein (RBP) and a 56% reduction in vitamin A deficiency (RBP

    Since its first emergence in 1998 in Malaysia, Nipah virus (NiV) has become a great threat to domestic animals and humans. Sporadic outbreaks associated with human-to-human transmission caused hundreds of human fatalities. Here, we collected all available NiV sequences and combined phylogenetics, molecular selection, structural biology and receptor analysis to study the emergence and adaptive evolution of NiV. NiV can be divided into two main lineages including the Bangladesh and Malaysia lineages. We formly confirmed a significant association with geography which is probably the result of long-term evolution of NiV in local bat population. The two NiV lineages differ in many amino acids; one change in the fusion protein might be involved in its activation via binding to the G protein. We also identified adaptive and positively selected sites in many viral proteins. In the receptor-binding G protein, we found that sites 384, 386 and especially 498 of G protein might modulate receptor-binding affinity and thus contribute to the host jump from bats to humans via the adaption to bind the human ephrin-B2 receptor. We also found that site 1645 in the connector domain of L was positive selected and involved in adaptive evolution; this site might add methyl groups to the cap structure present at the 5'-end of the RNA and thus modulate its activity. This study provides insight to assist the design of early detection methods for NiV to assess its epidemic potential in humans.

    Nipah virus (NiV), emerged in Peninsular Malaysia, caused an outbreak of severe febrile encephalitis in humans and respiratory diseases in pigs between 1998 and 1999. By May of 1999, the death of 105 humans and the culling of about 1.1 million pigs were reported. Fruitbats of Pteropid species were identified as the natural reservoir hosts. The epidemiological studies suggested that NiV was introduced into pig farms by fruitbats, and was than transmitted to humans (mainly pig farmers) and other animals such as dogs, cats and horses. In 2004, NiV reappeared in Bangladesh with greater lethality. In contrast to the Malaysia case, epidemiologic characteristics of this outbreak suggested the possibility of fruitbats-to-person, or person-to-person transmission. In this article, the epidemiological comparison between two outbreaks in Malaysia and Bangladesh, and the new-trends of virological studies of NiV will be discussed.

    The emergence of Hendra and Nipah viruses in the 1990s has been followed by the further emergence of these viruses in the tropical Old World. The history and current knowledge of the disease, the viruses and their epidemiology is reviewed in this article. A historical aside summarizes the role that Dr. Brian W.J. Mahy played at critical junctures in the early stories of these viruses.

    Coronavirus Disease 2019 (COVID-19) warrants comprehensive investigations of publicly available Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) genomes to gain new insight about their epidemiology, mutations, and pathogenesis. Nearly 0.4 million mutations have been identified so far among the ∼60,000 SARS-CoV-2 genomic sequences. In this study, we compared a total of 371 SARS-CoV-2 published whole genomes reported from different parts of Bangladesh with 467 sequences reported globally to understand the origin of viruses, possible patterns of mutations, and availability of unique mutations. Phylogenetic analyses indicated that SARS-CoV-2 viruses might have transmitted through infected travelers from European countries, and the GR clade was found as predominant in Bangladesh. Our analyses revealed 4604 mutations at the RNA level including 2862 missense mutations, 1192 synonymous mutations, 25 insertions and deletions and 525 other types of mutation. In line with the global trend, D614G mutation in spike glycoprotein was predominantly high (98 %) in Bangladeshi isolates. Interestingly, we found the average number of mutations in ORF1ab, S, ORF3a, M, and N were significantly higher (p < 0.001) for sequences containing the G614 variant compared to those having D614. Previously reported frequent mutations, such as R203K, D614G, G204R, P4715L and I300F at protein levels were also prevalent in Bangladeshi isolates. Additionally, 34 unique amino acid changes were revealed and categorized as originating from different cities. These analyses may increase our understanding of variations in SARS-CoV-2 virus genomes, circulating in Bangladesh and elsewhere.

    Mass mortalities of the larval stage of the giant freshwater prawn, Macrobrachium rosenbergii, have been occurring in Bangladesh since 2011. Mortalities can reach 100% and have resulted in an 80% decline in the number of hatcheries actively producing M. rosenbergii. To investigate a causative agent for the mortalities, a disease challenge was carried out using infected material from a hatchery experiencing mortalities. Moribund larvae from the challenge were prepared for metatranscriptomic sequencing. De novo virus assembly revealed a 29 kb single‑stranded positive-sense RNA virus with similarities in key protein motif sequences to yellow head virus (YHV), an RNA virus that causes mass mortalities in marine shrimp aquaculture, and other viruses in the Nidovirales order. Primers were designed against the novel virus and used to screen cDNA from larvae sampled from hatcheries in the South of Bangladesh from two consecutive years. Larvae from all hatcheries screened from both years were positive by PCR for the novel virus, including larvae from a hatchery that at the point of sampling appeared healthy, but later experienced mortalities. These screens suggest that the virus is widespread in M. rosenbergii hatchery culture in southern Bangladesh, and that early detection of the virus can be achieved by PCR. The hypothesised protein motifs of Macrobrachium rosenbergii golda virus (MrGV) suggest that it is likely to be a new species within the Nidovirales order. Biosecurity measures should be taken in order to mitigate global spread through the movement of post-larvae within and between countries, which has previously been linked to other virus outbreaks in crustacean aquaculture.

    Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder, common in clinic and in the community. It has a significant impact on both society and patients' quality of life. The epidemiology, clinical presentation, and management of IBS may vary in different geographical regions due to differences in diet, gastrointestinal infection, socio-cultural and psycho-social factors, religious and illness beliefs, symptom perception and reporting. Although previous reviews and consensus reports on IBS in Asia have been published, Asia is quite diverse socio-demographically. In this context, India, Bangladesh and Malaysia share some similarities, including: (1) large proportion of the population living in rural areas; (2) rapid development and associated lifestyle changes in urban areas; and (3) dietary, cultural and religious practices. The present review explores the clinical and epidemiological data on IBS from these three major nations in South and South-East Asia. In-depth review of the literature revealed important differences between IBS in the East, as revealed by studies from these three countries, and the West; these include a predominantly rural profile, differences in bowel habit and symptom profile, raising concern with regards to diagnostic criteria and subtyping of IBS, higher dietary fiber consumption, frequent lactose malabsorption, parasitosis, and possible overlap between post-infectious IBS and tropical sprue. Moreover, the current perception on difference in prevalence of the disorder in these countries, as compared to the West, might be related to variation in survey methods.
