Novel -Infecting Bacteriophages Isolated from Uganda That Target Human Clinical Isolates.

Background: The antimicrobial resistance catastrophe is a growing global health threat and predicted to be worse in developing countries. Phages for Global Health (PGH) is training scientists in these regions to isolate relevant therapeutic phages for pathogenic bacteria within their locality, and thus contributing to making phage technology universally available.

Materials And Methods: During the inaugural PGH workshop in East Africa, samples from Ugandan municipal sewage facilities were collected and two novel lytic phages were isolated and characterized.

Multilocus sequence analysis revealed a high genotypic diversity of Aeromonas hydrophila infecting fish in Uganda.

A multilocus sequence analysis (MLSA) was carried out to delineate Aeromonas hydrophila from fish in Uganda. Five housekeeping genes including recA, gyrB, metG, gltA and pps; and the 16S rRNA gene were amplified and sequenced from a total of nine A. hydrophila isolates.

Detection of tilapia lake virus (TiLV) infection by PCR in farmed and wild Nile tilapia (Oreochromis niloticus) from Lake Victoria.

Tilapia lake virus disease (TiLVD) has emerged to be an important viral disease of farmed Nile tilapia (Oreochromis niloticus) having the potential to impede expansion of aquaculture production. There is a need for rapid diagnostic tools to identify infected fish to limit the spread in individual farms. We report the first detection of TiLV infection by PCR in farmed and wild Nile tilapia from Lake Victoria.

The Development of -Specific IL10 CD4 T Cells and Protection from Malaria in Children in an Area of High Malaria Transmission.

Cytokine-producing CD4 T cells have important roles in immunity against malaria. However, the factors influencing functional differentiation of specific CD4 T cells in naturally exposed children are not well understood. Moreover, it is not known which CD4 T-cell cytokine-producing subsets are most critical for protection.

Men's Perceptions of Women's Participation in Development Initiatives in Rural Bangladesh.

Without taking masculine issues into account, women's participation in development initiatives does not always guarantee their empowerment, health, and welfare in a male-dominated society. This study aimed to explore men's perceptions of women's participation in development (WPD) in rural Bangladesh. In adopting a qualitative approach, the study examined 48 purposively selected married and unmarried men aged 20-76 years in three northwest villages.

Sex Disparity in Cord Blood FoxP3 CD4 T Regulatory Cells in Infants Exposed to Malaria In Utero.

Sex differences in the immune response and in infectious disease susceptibility have been well described, although the mechanisms underlying these differences remain incompletely understood. We evaluated the frequency of cord blood CD4 T cell subsets in a highly malaria-exposed birth cohort of mother-infant pairs in Uganda by sex. We found that frequencies of cord blood regulatory T cell ([T] CD4CD25FoxP3CD127) differed by infant sex, with significantly lower frequencies of T in female than in male neonates ( = .

Timing of in utero malaria exposure influences fetal CD4 T cell regulatory versus effector differentiation.

Background: In malaria-endemic areas, the first exposure to malaria antigens often occurs in utero when the fetal immune system is poised towards the development of tolerance. Children exposed to placental malaria have an increased risk of clinical malaria in the first few years of life compared to unexposed children. Recent work has suggested the potential of pregnancy-associated malaria to induce immune tolerance in children living in malaria-endemic areas.

Gender and Women Development Initiatives in Bangladesh: A Study of Rural Mother Center.

Women-focused development initiatives have become a controversial issue connected with women's health and welfare. Previous studies indicated that development initiatives might increase women's workload, family conflict, and marital violence. This study explored the gendered characteristics of a development initiative Rural Mother Center in Bangladesh.

Effective Antimalarial Chemoprevention in Childhood Enhances the Quality of CD4+ T Cells and Limits Their Production of Immunoregulatory Interleukin 10.

Background: Experimental inoculation of viable Plasmodium falciparum sporozoites administered with chemoprevention targeting blood-stage parasites results in protective immunity. It is unclear whether chemoprevention similarly enhances immunity following natural exposure to malaria.

Methods: We assessed P.

B cell sub-types following acute malaria and associations with clinical immunity.

Background: Repeated exposure to Plasmodium falciparum is associated with perturbations in B cell sub-set homeostasis, including expansion atypical memory B cells. However, B cell perturbations immediately following acute malaria infection have been poorly characterized, especially with regard to their relationship with immunity to malaria.

Methods: To better understand the kinetics of B cell sub-sets following malaria, the proportions of six B cell sub-sets were assessed at five time points following acute malaria in four to 5 years old children living in a high transmission region of Uganda.

Frequent Malaria Drives Progressive Vδ2 T-Cell Loss, Dysfunction, and CD16 Up-regulation During Early Childhood.

γδ T cells expressing Vδ2 may be instrumental in the control of malaria, because they inhibit the replication of blood-stage parasites in vitro and expand during acute malaria infection. However, Vδ2 T-cell frequencies and function are lower among children with heavy prior malaria exposure. It remains unclear whether malaria itself is driving this loss.

Decline of FoxP3+ Regulatory CD4 T Cells in Peripheral Blood of Children Heavily Exposed to Malaria.

FoxP3+ regulatory CD4 T cells (Tregs) help to maintain the delicate balance between pathogen-specific immunity and immune-mediated pathology. Prior studies suggest that Tregs are induced by P. falciparum both in vivo and in vitro; however, the factors influencing Treg homeostasis during acute and chronic infections, and their role in malaria immunopathogenesis, remain unclear.

Swedish public health policy: Impact on regional and local public health practice and priorities.

We evaluated the Swedish National Public Health Policy to determine its impact on public health priorities and practice at regional and local levels between 2004 and 2013. We conducted a survey by questionnaire in February 2013 among Swedish county councils/regions (n=19/21), and municipalities (n=219/290). The National Public Health Policy facilitated systematic public health practice, particularly for planning, for high priority concerns, including conditions during childhood and adolescence, physical activity, and tobacco prevention.

IFNγ Responses to Pre-erythrocytic and Blood-stage Malaria Antigens Exhibit Differential Associations With Past Exposure and Subsequent Protection.

Background: The malaria-specific T-cell response is believed to be important for protective immunity. Antimalarial chemoprevention may affect this response by altering exposure to malaria antigens.

Methods: We performed interferon γ (IFNγ) ELISpot assays to assess the cellular immune response to blood-stage and pre-erythrocytic antigens longitudinally from 1 to 3 years of age in 196 children enrolled in a randomized trial of antimalarial chemoprevention in Tororo, Uganda, an area of high transmission intensity.

IFNγ/IL-10 co-producing cells dominate the CD4 response to malaria in highly exposed children.

Although evidence suggests that T cells are critical for immunity to malaria, reliable T cell correlates of exposure to and protection from malaria among children living in endemic areas are lacking. We used multiparameter flow cytometry to perform a detailed functional characterization of malaria-specific T cells in 78 four-year-old children enrolled in a longitudinal cohort study in Tororo, Uganda, a highly malaria-endemic region. More than 1800 episodes of malaria were observed in this cohort, with no cases of severe malaria.

Differential returns from globalization to women smallholder coffee and food producers in rural Uganda.

Background: Globalization-related measures to liberalize trade and stimulate export production were applied in Uganda in the late 1980s, including in the coffee production sector, to revitalize agricultural production, increase incomes to farmers and improve rural food security.

Objective: To explore the different effects of such measures on the health and dietary outcomes of female coffee and food small holder farmers in Uganda.

Methods: We gathered evidence through a cross-sectional comparative interview survey of 190 female coffee producers and 191 female food producers in Ntungamo district.

The Swedish national public health policy report 2010.

Background: In 2003, the Swedish Parliament adopted a cross-sectorial national public health policy based on the social determinants of health, with an overarching aim--to create societal conditions that will ensure good health, on equal terms, for the entire population--and eleven objective domains. At that time the policy was globally unique, and serves as guidance for public health practice at the national, regional and local levels. The development of the public health policy and the determinants of health are presented regularly in various reports by the Swedish National Institute of Public Health.

Water development projects and marital violence: experiences from rural Bangladesh.

In this study, we explored the implications of a groundwater development project on women's workload and their experience of marital violence in a Bangladesh village. We believe that the project facilitated irrigation water but also that it resulted in seasonal domestic water shortages. Men used deep motorized pumps for irrigation, and women used shallow handpumps for domestic purposes.

Social determinants of health--a question of social or economic capital? Interaction effects of socioeconomic factors on health outcomes.

Social structures and socioeconomic patterns are the major determinants of population health. However, very few previous studies have simultaneously analysed the "social" and the "economic" indicators when addressing social determinants of health. We focus on the relevance of economic and social capital as health determinants by analysing various indicators.

Economic hardships in adulthood and mental health in Sweden. The Swedish National Public Health Survey 2009.

Background: Possible accumulative effects of a combined economic hardship's measure, including both income and non-income related economic hardships measures, on mental health has not been well investigated. The aim of this paper was to investigate; (i) independent associations between multiple measures of economic hardships and mental health problems, and (ii) associations between a combined economic hardships measure and mental health problems.

Methods: We analysed data from the 2009 Swedish National Survey of Public Health comprising a randomly selected representative national sample combined with a randomly selected supplementary sample from four county councils and three municipalities consisting of 23,153 men and 28,261 women aged 16-84 years.

What has trust in the health-care system got to do with psychological distress? Analyses from the national Swedish survey of public health.

Objective: Mental health disorders are a rapidly growing public health problem. Despite the fact that lack of trust in the health-care system is considered to be an important determinant of health, there is scarcity of empirical evidence demonstrating its associations with health outcomes. This is the first study which aims to evaluate the association between trust in the health-care system and psychological distress.

Can the Millennium Development Goals database be used to measure the effects of globalisation on women's health in Sub-Saharan Africa? A critical analysis.

Background: Africa has had poor returns from integration with world markets in globalisation, has experienced worsening poverty and malnutrition and has high burdens of HIV and communicable disease, with particular burdens on women. It is therefore essential to describe the impact of globalisation on women's health. Indicators such as the Millennium Development Goals (MDGs) are presented as having a major role in measuring this impact, but an assessment of the adequacy of aggregate national indicators used in monitoring the MDGs for this purpose is lacking.

Review article: Globalisation and women's health in Sub-Saharan Africa: would paying attention to women's occupational roles improve nutritional outcomes?

Aim: This paper explores, through a review of literature, the link between globalisation and nutritional outcomes in Sub-Saharan Africa, focusing on the pathways of women's occupational roles on the food produced, consumed, and secured for households.

Methods: Following a framework linking globalisation and health, we drew evidence from peer reviewed, cross-national or large scale studies, official sources, reviews, online scientific databases, and case studies, published between 1990 and 2009.

Results: Publications cite improved technology, information, know how, normative commitments to and resources for human development, returns from access to investment in agriculture for low-income women producers, and urban employment opportunities reducing social discrimination and improving opportunities for household food security, particularly if access to these benefits is reinforced by national policy.
