Impact of the antiretroviral treatment program on the burden of hospitalization for culture-confirmed tuberculosis in South African children: a time-series analysis

The HIV epidemic increased the burden of tuberculosis (TB) in sub-Saharan Africa. We evaluated the impact that scaling-up of the public-funded antiretroviral treatment (ART) program had on incidence of hospitalization for culture-confirmed and overall-TB in HIV-infected and HIV-uninfected children from 2005 to 2009. The study was undertaken in Soweto, South Africa, where ART coverage of HIV-infected children increased from 43% in 2005 to 84% by 2009. Trends in incidence of hospitalization for clinically diagnosed and culture-confirmed TB in children 3 months to <15 years of age, identified through laboratory and electronic databases, were analyzed by comparing crude incidence and regression analysis. The incidence (per 100,000) of culture-confirmed TB declined by 63.1% from 2005 (69.8) compared with 2009 (25.8; P < 0.0001). This included a 70.6% reduction between 2005 and 2009 among HIV-infected children (incidence: 1566.3 versus 460.7, respectively; P < 0.0001) and 41.3% decrease in HIV-uninfected children (18.7 versus 11.0, respectively; P = 0.0003). The month-by-month rate of decline of culture-confirmed TB was 2.3% in HIV-infected and 1.1% in HIV-uninfected children over the study period. The residual burden of TB remained ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
