Effect of HIV status and retinol on immunogenicity to oral cholera vaccine in adult population living in an endemic area of Lukanga Swamps, Zambia.

Background: We set out to assess the impact of human immunodeficiency virus (HIV) and micronutrient deficiency as indicated by serum retinol levels on the immune responses to Oral Cholera Vaccine (Shanchol™) in a cohort of participants in Lukanga Swamps, Zambia. Cholera remains endemic in Zambia with vaccines being the only effective preventive measures. However, the effect of these vaccines on populations living with HIV has not been widely documented.

Challenges Encountered When Evaluating an Antibody-Detecting Point-of-Care Test for Taeniosis in an Endemic Community in Zambia: A Prospective Diagnostic Accuracy Study.

taeniosis diagnosis is challenging because current tests perform sub-optimally and/or are expensive, require sophisticated equipment, infrastructure and trained manpower, and therefore are not community deployable. A recently-developed, multi-strip, point-of-care test (TS POC) for simultaneous detection of tapeworm (TS POC T) and cysticercus (TS POC CC) human antibodies was evaluated for diagnostic accuracy on consecutively recruited community participants in Sinda district, Zambia. All participants were tested using the TS POC test.

Drug shops for stronger health systems: learning from initiatives in six LMICs.

Background: Private sector retail pharmacies, or drug shops, play an important role in access to essential medicines and services in low-and-middle-income countries. Recognising that they have the potential to contribute to health system strengthening efforts, many recent initiatives to engage with drug shops have been launched. These include initiatives that focus on changes in policy, regulation and training.

Human Milk output among mothers previously treated for severe acute malnutrition in childhood in Democratic Republic of Congo.

Background: Malnutrition is a public health problem, as wasting affects 7.5% of children worldwide. The harmful effects of severe acute malnutrition (SAM) can last a lifetime, but how SAM in childhood affects later breastfeeding ability is not clear.

Trial Design of a Prospective Multicenter Diagnostic Accuracy Study of a Point-of-Care Test for the Detection of Taeniosis and Neurocysticercosis in Hospital-Based Settings in Tanzania.

diagnosis is challenging as trained personnel, good diagnostic tools, and infrastructure is lacking in resource-poor areas. This paper aims to describe the study trial design adopted to evaluate a newly developed rapid point-of-care test that simultaneously detects taeniosis and neurocysticercosis (TS POC) in three district hospitals in Tanzania. The two-stage design included three types of patients: patients with specific neurological signs and symptoms (group 1); patients with complaints compatible with intestinal worm infections (group 2); patients with other symptom(s) (group 3).

Norms and sexual relations among adolescents in the context of an intervention trial in rural Zambia.

High levels of adolescent pregnancy and child marriage rates in low- and middle-income countries is an issue of concern to many stakeholders, including in Zambia where almost one-third of women give birth before age 18. The aim of this paper is to explore and analyse social norms concerning adolescents' sexual behaviour within the context of an intervention trial in rural communities in southern Zambia. It is based on a qualitative study applying individual interviews, focus group discussions and participatory research methods.

Improving Sampling Efficiency for Determining Pediatric HIV Prevalence in National Surveys: Evidence From 8 Sub-Saharan African Countries.

Background: Measurement of mother-to-child HIV transmission through population-based surveys requires large sample sizes because of low HIV prevalence among children. We estimate potential improvements in sampling efficiency resulting from a targeted sample design.

Setting: Eight countries in sub-Saharan Africa with completed Population-based HIV Impact Assessment (PHIA) surveys as of 2017.

Interaction of Quinolones Carrying New R1 Group with DNA Gyrase.

Leprosy is a chronic infectious disease caused by and the treatment of choice is ofloxacin (OFX). Specific amino acid substitutions in DNA gyrase of have been reported leading to resistance against the drug. In our previous study, WQ-3810, a fluoroquinolone with a new R1 group (6-amino-3,5-difluoropyridin-2-yl) was shown to have a strong inhibitory activity on OFX-resistant DNA gyrases of , and the structural characteristics of its R1 group was predicted to enhance the inhibitory activity.

Mitochondrial DNA Instability Is Common in HIV-Exposed Uninfected Newborns.

Worldwide, one million HIV-exposed uninfected (HEU) children are born yearly, and chronic health impairments have been reported in these children. Mitochondrial DNA (mtDNA) instability and altered mtDNA content have been evidenced in these children, but an exhaustive characterization of altered mitochondrial genomes has never been reported. We applied deep mtDNA sequencing coupled to the deletion identification algorithm eKLIPse to the blood of HEU neonates ( = 32), which was compared with healthy controls ( = 15).

Combination of Levamisole with Prednisone in Treating Recurrent Major Aphthous Ulcer in a Young Boy: A Case Report.

Recurrent aphthous stomatitis (RAS) is an oral condition characterized by painful oral ulcerations. While the clinical features of this disease are easily defined, the etiology remains unclear. Thus, existing treatments are still unsatisfactory in reducing the severity, healing, and recurrence rate; however, there is no permanent and definitive treatment.

Defeating Paediatric Tuberculous Meningitis: Applying the WHO "Defeating Meningitis by 2030: Global Roadmap".

Children affected by tuberculous meningitis (TBM), as well as their families, have needs that lie at the intersections between the tuberculosis and meningitis clinical, research, and policy spheres. There is therefore a substantial risk that these needs are not fully met by either programme. In this narrative review article, we use the World Health Organization (WHO) "Defeating Meningitis by 2030: global roadmap" as a starting point to consider key goals and activities to specifically defeat TBM in children.

Molecular epidemiology of Mycobacterium bovis in central parts of Malawi.

Bovine tuberculosis (bTB) is a neglected disease that affects cattle and humans. The burden of bTB is higher in developing countries as compared to industrialized countries. The reasons behind this discrepancy include the fact that bTB control measures, such as testing and slaughter of infected cattle and pasteurization of milk, are not usually practised in developing countries largely because of their high cost.

Stable high-density and maternally inherited Wolbachia infections in Anopheles moucheti and Anopheles demeilloni mosquitoes.

Wolbachia, a widespread bacterium that can reduce pathogen transmission in mosquitoes, has recently been reported to be present in Anopheles (An.) species. In wild populations of the An.

Retrospective evaluation of the effectiveness of indoor residual spray with pirimiphos-methyl (Actellic) on malaria transmission in Zambia.

Background: Widespread insecticide resistance to pyrethroids could thwart progress towards elimination. Recently, the World Health Organization has encouraged the use of non-pyrethroid insecticides to reduce the spread of insecticide resistance. An electronic tool for implementing and tracking coverage of IRS campaigns has recently been tested (mSpray), using satellite imagery to improve the accuracy and efficiency of the enumeration process.

User Experience With Low-Cost Virtual Reality Cancer Surgery Simulation in an African Setting.

Purpose: Limited access to adequate cancer surgery training is one of the driving forces behind global inequities in surgical cancer care. Affordable virtual reality (VR) surgical training could enhance surgical skills in low- and middle-income settings, but most VR and augmented reality systems are too expensive and do not teach open surgical techniques commonly practiced in these contexts. New low-cost VR can offer skill development simulations relevant to these settings, but little is known about how knowledge is gained and applied by surgeons training and working in specific resource-constrained settings.

A Novel Sample Selection Approach to Aid the Identification of Factors That Correlate With the Control of HIV-1 Infection.

Individuals infected with HIV display varying rates of viral control and disease progression, with a small percentage of individuals being able to spontaneously control infection in the absence of treatment. In attempting to define the correlates associated with natural protection against HIV, extreme heterogeneity in the datasets generated from systems methodologies can be further complicated by the inherent variability encountered at the population, individual, cellular and molecular levels. Furthermore, such studies have been limited by the paucity of well-characterised samples and linked epidemiological data, including duration of infection and clinical outcomes.
