Tuberculosis (TB) is a serious disease of public health concern, mainly in low- and middle-income countries. Most of these countries have challenges in diagnosis and treatment of TB in people with smear-negative pulmonary tuberculosis (SNPTB), which remains a significant public health challenge because of the global burden of the disease. We evaluated the epidemiology and clinical presentation of SNPTB in a cohort of patients with high HIV burden.

Methods: The study was a cross-sectional study among patients with SNPTB.

We investigated the effect of cART (RT and protease inhibitors) on the content of extracellular vesicles (EVs) released from HIV-1-infected cells. We have previously shown that EVs contain non-coding HIV-1 RNA, which can elicit responses in recipient cells.

The magnitude of this problem is not well-studied in sub-Saharan Africa.
Materials And Methods: We conducted a cross-sectional survey of stroke patients at a tertiary hospital during January 2010 to July 2013 to determine patient awareness of a pre-existing stroke risk factor and prior use of anti-hypertensive, anti-diabetic, antiplatelet and lipid-lowering agents.
Spinocerebellar ataxia type-7 (SCA7) is a cytosine-adenine-guanine (CAG) repeat polyglutamine disorder characterized by progressive degeneration of the cerebellum, brainstem, spinal cord, and retina. Clinical features include progressive ataxia, visual loss, pyramidal weakness, sensory impairment, and dementia. Among the autosomal dominant cerebellar ataxias, SCA7 is relatively common in Scandinavia and South Africa but rare worldwide and is not previously reported in Nigeria.

In this study 149 antiretroviral-naïve seropositive subjects in Nigeria (SP, 92 women and 57 men) and 58 seronegative (SN, 38 women and 20 men) were administered neuropsychological testing that assessed 7 ability domains. From the neuropsychological test scores was calculated a global deficit score (GDS), a measure of overall NCI.

A better understanding of stroke risk factors and outcome may help guide efforts at reducing the community burden of stroke. This study aimed to understand stroke risk factors, imaging subtypes, and 30-day outcomes among adult Nigerians.

A good understanding of NeuroAIDS may help improve disease-free survival in patients at risk and optimize resource utilization by caregivers. In this review, we aimed to provide a summary of major NeuroAIDS syndromes of relevance in Africa.

Limited data exist on the impact of early asymptomatic HIV infection on cognition in developing nations, and indeed none from Nigeria. Hence, this cross-sectional study sets out to determine whether there are differences between Nigerian asymptomatic HIV-seropositive and HIV-seronegative subjects, and whether such differences: if any, could be explained by the degree of immunosuppression (i.
