Characterization of a Novel P[25],G11 Human Group A Rotavirus

Abstract: A novel rotavirus strain (Dhaka6) isolated from a 21-year-old Bangladeshi male patient was characterized by sequence analysis of its VP7 and VP4 gene segments. Phylogenetic analysis of the VP7 gene of the Dhaka6 strain revealed a common evolutionary lineage with porcine G11 rotavirus strains. This isolate is the first reported G11 rotavirus strain infecting a human host. Comparison of the VP4 gene sequences with all currently recognized 24 different P genotypes revealed only low nucleotide (54 to 71%) and amino acid (52 to 76%) sequence identities. This lack of high sequence similarity in the VP4 gene indicates that the Dhaka6 isolate represents a new group A rotavirus P genotype, to which we propose assignment of the designation P[25].

Living on the Extreme Margin: Social Exclusion of the Transgender Population (Hijra) in Bangladesh

Abstract: The transgender people (hijra), who claim to be neither male nor female, are socially excluded in Bangladesh. This paper describes social exclusion of hijra [The term is used in this abstract both in singular and plural sense] focusing on the pathway between exclusion and sexual health. In an ethnographic study, 50 in-depth interviews with hijra, 20 key-informant interviews, and 10 focus-group discussions (FGDs), along with extensive field observations, were conducted. The findings revealed that hijra are located at the extreme margin of exclusion having no sociopolitical space where a hijra can lead life of a human being with dignity. Their deprivations are grounded in non-recognition as a separate gendered human being beyond the male-female dichotomy. Being outside this norm has prevented them from positioning themselves in greater society with human potential and security. They are physically, verbally, and sexually abused. Extreme social exclusion diminishes self-esteem and sense of social responsibility. Before safer sex interventions can be effective in a broader scale, hijra need to be recognized as having a space on society's gender continuum. Hijra , as the citizens of Bangladesh and part of society's diversity, have gender, sexual and citizenship rights, that need to be protected.

Influenza is a major contributor to childhood pneumonia in a tropical developing country.

Abstract: Background: Pneumonia is the leading cause of child mortality worldwide. The role of influenza in childhood pneumonia in tropical developing countries is poorly understood. We undertook population-based surveillance among low-income urban preschool children to determine its role in childhood pneumonia. Methods: Longitudinal prospective active surveillance was conducted among randomly selected households in a poor urban area of Dhaka. Nasopharyngeal washes were collected from 1 in 5 children for influenza culture isolation. Clinical data were collected at clinical presentation and through the illness course. Results: From April 1, 2004 through December 31, 2007, 12,062 children presented in clinic with eligible febrile and respiratory illnesses, from whom 321 influenza isolates were obtained from 2370 nasopharyngeal washes (13.5%), representing 16,043 child-years of observation (adjusted influenza incidence 102 episodes/1000 child-years). There were 8198 pneumonia episodes during the period (pneumonia incidence 511 episodes/ 1000 child-years). Ninety influenza-positive children (28%) developed pneumonia during their illness. Among influenza culture-positive children, those with pneumonia were younger than those without (23.4 vs. 29.7 months, ANOVA: P 0.001). Pneumonia was more commonly associated with Influenza A (H3N2) than either A (H1N1) or B infections (ageadjusted relative odds (RO) 2.98, 95% CI: 1.56, 5.71 and 2.75, 95% CI: 1.52, 4.98, respectively). Influenza was associated with 10% all childhood pneumonia. Conclusions: Influenza is a major contributor to childhood pneumonia both through high influenza infection incidence and high pneumonia prevalence among infected children. Its contribution to early childhood pneumonia appears under-appreciated in high pneumonia-endemic tropical settings. Influenza vaccine trials against childhood pneumonia are warranted.

Randomized, placebo-controlled, clinical trial of hyperimmunized chicken egg yolk immunoglobulin in children with rotavirus diarrhea.

Abstract: BackgroundHyperimmunized bovine colostrum containing antibodies has been shown to be effective in the treatment of rotavirus diarrhea. Antibodies derived from eggs of immunized hens may be a less expensive and more practical alternative. In this study, children with proven rotavirus diarrhea

El Tor cholera with severe disease: a new threat to Asia and beyond.

Abstract: During epidemics of cholera in two rural sites (Bakerganj and Mathbaria), a much higher proportion of patients came for treatment with severe dehydration than was seen in previous years. V. cholerae O1 isolated from these patients was found to be El Tor in its phenotype, but its cholera toxin (CT) was determined to be that of classical biotype. Whether the observed higher proportion of severe dehydration produced by the El Tor biotype was due to a shift from El Tor to classical CT or due to other factors is not clear. However, if cholera due to strains with increased severity spread to other areas where treatment facilities are limited, there are likely to be many more cholera deaths.
