Sexually Transmitted Infections
In Africa, STI testing could boost HIV prevention
Sexually transmitted infections can make HIV transmission more likely, undermining the prevention benefit of HIV treatment. A new study of HIV-positive patients in Cape Town, South Africa, found that the prevalence of such co-infections was much higher before beginning HIV treatment. Testing for and treating STIs and HIV together could therefore improve HIV prevention.

Experimental trial represents promising step toward universal antidote for snakebite
A team of researchers, led by Dr. Matthew Lewin of the California Academy of Sciences and Dr. Stephen P. Samuel of Trinity College Dublin, Ireland has taken another promising step toward developing a universal antidote for snakebite. The results of this pilot study were recently published in the Journal of Tropical Medicine. These findings support the team's idea that providing fast, accessible, and easy-to-administer treatment can increase survival rates in victims of venomous snakebite.

Nearly one-third of the world's population is obese or overweight, new data show
Today, 2.1 billion people -- nearly 30 percent of the world's population -- are either obese or overweight, according to a new, first-of-its kind analysis of trend data from 188 countries. The rise in global obesity rates over the last three decades has been substantial and widespread, presenting a major public health epidemic in both the developed and the developing world.

Barriers to HIV testing in older children
Concerns about guardianship and privacy can discourage clinics from testing children for HIV, according to new research from Zimbabwe published this week in PLOS Medicine. The results of the study, by Rashida A. Ferrand of the London School of Hygiene & Tropical Medicine and colleagues, provide much-needed information on how to improve care of this vulnerable population.

Scientists identify potential vaccine candidate for pediatric malaria
Researchers have identified a substance, or antigen, that generates antibodies that can hinder the ability of malaria parasites to multiply, which may protect against severe malaria infection. The antigen, known as PfSEA-1, was associated with reduced parasite levels among children and adults in malaria-endemic areas.

RI Hospital researcher and colleagues discover protein that may lead to malaria vaccine
Rhode Island Hospital researchers have discovered a protein that is essential for malaria-causing parasites to escape from inside red blood cells. This protein could lead to the development of a vaccine that would prevent the progression of Plasmodium falciparum malaria, which kills one child every 15 seconds each year in Sub-Saharan Africa and Southeast Asia, according to new research by Jonathan Kurtis, M.D., Ph.D., and colleagues.

Scientist uncovers links connecting environmental changes with spike in infectious disease
Smithsonian scientist Bert Van Bocxlaer and a team of researchers revealed that anthropogenic changes in Africa's Lake Malaŵi are a driving force behind the increase of urogenital schistosomiasis, a debilitating disease caused by parasitic flatworms. In some villages along Lake Malaŵi, 73 percent of people and up to 94 percent of schoolchildren are infected. The research suggests the spike in infection is linked to an increase in human populations and agricultural activities near Lake Malaŵi.

Protein sharpens salmonella needle for attack
A tiny nanoscale syringe is Salmonella's weapon. Using this, the pathogen injects its molecular agents into the host cells and manipulates them to its own advantage. Scientists at the Biozentrum of the University of Basel demonstrate in their current publication in Cell Reports that a much investigated protein, which plays a role in Salmonella metabolism, is required to activate these needles and makes the replication and spread of Salmonella throughout the whole body possible.

How some trypanosomes cause sleeping sickness while others don't
Trypanosome parasites transmitted by tsetse flies cause devastating diseases in humans and livestock. Different subspecies infect different hosts: Trypanosoma brucei brucei infects cattle but is non-infectious to humans, whereas T. b. gambiense and T. b. rhodesiense cause sleeping sickness in humans. A study published on May 15th in PLOS Pathogens reveals how humans can fight off some trypanosomes but not others.

Zinc supplementation boosts immune system in children, Cochrane Review finds
Zinc supplements reduce diarrhoea and other infections in malnourished children, and may prevent death, according to a new study published in The Cochrane Library. The study is the first Cochrane systematic review to focus on zinc as a means to prevent childhood death, including deaths caused by diarrhea, one of the biggest killers of under-fives.

Hitting a moving target
A vaccine or other therapy directed at a single site on a surface protein of HIV could in principle neutralize nearly all strains of the virus -- thanks to the diversity of targets the site presents to the human immune system.

Understanding the 1918 flu pandemic can aid in better infectious disease response
The 1918 Flu Pandemic infected over 500 million people, killing at least 50 million. Now, a researcher at the University of Missouri has analyzed the pandemic in two remote regions of North America, finding that despite their geographical divide, both regions had environmental, nutritional and economic factors that influenced morbidity during the pandemic. Findings from the research could help improve current health policies.

Pretreatment snack improves uptake of schistosomiasis treatment in schoolchildren
Provision of a snack before mass treatment of schistosomiasis with praziquantel leads to increased uptake of treatment in school-aged children in Uganda, according to a study published in this week's PLOS Medicine. Simon Muhumuza and colleagues from Makerere University, Kampala, Uganda found that 93.9 percent of children reported taking praziquantel in schools that offered a snack before treatment compared with 78.7 percent of children in schools that did not offer a snack.

PSC, Hopkins computer model helps Benin vaccinate more kids at lower cost
Researchers from Pittsburgh Supercomputing Center, the University of Pittsburgh School of Engineering and the Johns Hopkins Bloomberg School of Public Health have used HERMES, their modeling software, to help the Republic of Benin in West Africa determine how to bring more lifesaving vaccines to its children. Results from the HERMES model have helped the country enact some initial changes in their vaccine delivery system, which may lead to further changes nationwide.

Hepatitis C virus: How viral proteins interact in human cells
Scientists at the Helmholtz Zentrum München have for the first time decrypted the interaction network of hepatitis C virus proteins in living human cells. Their findings will contribute to a better understanding of the mechanisms behind inflammatory liver disease caused by hepatitis C viruses and open up new avenues for therapy development. The results are published in the specialist journal Molecular & Cellular Proteomics.

Mass vaccination campaigns reduce the substantial burden of yellow fever in Africa
Yellow fever, an acute viral disease, is estimated to have been responsible for 78,000 deaths in Africa in 2013 according to new research published in PLOS Medicine this week. The research by Neil Ferguson from Imperial College London, UK and colleagues from Imperial College, WHO and other institutions also estimates that recent mass vaccination campaigns against yellow fever have led to a 27 percent decrease in the burden of yellow fever across Africa in 2013.
