TL;DR: Neither antenatal nor postpartum mental morbidity, as indicated by a self-reporting questionnaire 20-item (SRQ-20) score ≥7, were associated with HIV status or with post partum physical morbidity in this population of women in Lusaka, Zambia.
Abstract: The objective of our study was to investigate factors associated with postpartum physical and mental morbidity among women in Lusaka, Zambia with particular reference to known HIV status. Our study was part of the Breastfeeding and Postpartum Health (BFPH) longitudinal cohort study conducted between June 2001 and July 2003. Women were recruited at 34 weeks gestation and followed up to 16 weeks postpartum. Data on maternal health were collected at 3, 7, 10, and 14 days and at 3, 4, 5, 6, 9, 12, and 16 weeks postpartum. Maternal mental health data were collected from April 2002 onwards at recruitment and at seven days and six weeks postpartum. Data on physical morbidity were collected for 429 women (218 HIV-negative, 211 HIV-positive) and data on mental morbidity were collected for 272 women (134 HIV-negative, 138 HIV-positive). Multivariate logistic regression was used to examine factors associated with postpartum physical or mental morbidity. Postpartum physical morbidity was associated with HIV status, parity > or =5 and age or =7, were associated with HIV status or with postpartum physical morbidity in this population. Larger comparative studies are required to corroborate or contest these findings.

TL;DR: This review discusses some of the documented immunological evasion mechanisms African trypanosomes employ for their survival and perpetuity.
Abstract: Unlike other protozoan parasites, African trypanosomes never enter the host cell at any stage of their development. Instead, these parasites swim freely in the immunologically hostile host tissue fluids. During the course of infection, a complex interaction between the host immune responses and trypanosome survival strategies occurs. Continued contacts with the host's immune system occurring during the course of infection could have provided strong selection pressure for African trypanosomes to evolve very sophisticated mechanisms to evade immune killing to survive the hostile immunological environment in the infected host. This review discusses some of the documented immunological evasion mechanisms African trypanosomes employ for their survival and perpetuity.

TL;DR: An estimate of the prevalence of infection and which respiratory pathogens are commonly identified in patients are provided and single infections and co-infections of many viruses and bacteria were identified in children with SARI in Zambia.
Abstract: Morbidity and mortality from respiratory infections are higher in resource-limited countries than developed countries, but limited studies have been conducted in resource-limited settings to examine pathogens from patients with acute respiratory infections. Influenza surveillance has been conducted in Zambia since 2008; however, only 4.3% of patients enrolled in 2011–2012 were positive for influenza. Therefore, we examined non-influenza respiratory pathogens in children with severe acute respiratory illness (SARI) in Zambia, to estimate the scope of disease burden and determine commonly-identified respiratory pathogens. Two reverse transcriptase polymerase chain reaction (rRT-PCR) methods (single and multiplex) were used to analyze nasopharyngeal and throat swabs collected from SARI cases under five years of age from January 2011 through December 2012. All specimens were negative for influenza by rRT-PCR. The panel of singleplex reactions targeted seven viruses, while the multiplex assay targeted thirty-three bacteria, fungi, and viruses. A set of 297 specimens were tested by singleplex rRT-PCR, and a different set of 199 were tested by multiplex rRT-PCR. Using the singleplex assay, 184/297 (61.9%) specimens were positive for one or more viruses. The most prevalent viruses were human rhinovirus (57/297; 19.2%), human adenovirus (50/297; 16.8%), and respiratory syncytial virus (RSV) (45/297; 15.2%). Using multiplex PCR, at least one virus was detected from 167/199 (83.9%) specimens, and at least one bacteria was detected from 197/199 (99.0%) specimens. Cytomegalovirus (415/199; 208.5%) and RSV (67/199; 33.7%) were the most commonly detected viruses, while Streptococcus pneumonie (109/199; 54.8%) and Moraxella catarrhalis (92/199; 46.2%) were the most commonly detected bacteria. Single infections and co-infections of many viruses and bacteria were identified in children with SARI. These results provide an estimate of the prevalence of infection and show which respiratory pathogens are commonly identified in patients. Further studies should investigate causal associations between individual pathogens and SARI.

TL;DR: Children in Siavonga, a tourist centre on the Zambian side of Lake Kariba, have been found to be infected with both urinary and intestinal schistosomiasis, indicating that there is active transmission of the diseases in the area.
Abstract: Children in Siavonga, a tourist centre on the Zambian side of Lake Kariba, have been found to be infected with both urinary and intestinal schistosomiasis, indicating that there is active transmission of the diseases in the area. The snails involved seem to be Bulinus africanus and Biomphalaria pfeifferi, and it is suggested that mats of the water weed Salvinia auriculata could provide microhabitats for colonies of the snail and thereby provide foci for the transmission of the diseases.

TL;DR: One in five mothers of PWE feel stigmatized because of their child's epilepsy, and educating caregivers about epilepsy and screening for anxiety and depression are warranted.
