The research, which followed over 500 seniors, identified that overnight denture wear was independently associated with a 2.3-fold higher risk of pneumonia incidence.
A new study suggests that vaccines developed for adolescents and adults could have a significant impact on tuberculosis (TB) worldwide. The researchers found that these vaccines could provide dramatic levels of control needed to eliminate TB by 2050. However, the current BCG vaccine given to infants is not enough to achieve this goal.
A new study analyzing the first outbreak of Ebola in 1976 found that reducing community transmission and changing behavior were crucial to controlling the outbreak. The study suggests that if communities had not changed their behavior, the outbreak could have been much larger, with potentially devastating consequences.
The current Ebola outbreak in West Africa requires a rapid global response to contain the virus, which has already killed nearly 2000 people and may infect up to 20,000. Experts warn that fear, mistrust, and lack of resources are exacerbating the situation.
Researchers have devised a genetic barcode that can identify different types of tuberculosis (TB) bacteria, allowing doctors to track the spread of the disease more effectively.

A recent study found that older firefighters who are chronically exposed to heat stress on the job may be able to tolerate more challenging work environments before feeling affected by the heat. This increased heat resilience could enable them to perform tasks without stopping due to thermal strain, thereby reducing the risk of injurie...
A new Cochrane review shows that non-specialist health workers, such as doctors and nurses, can alleviate depression and anxiety in people with mental health problems. Non-specialists may also help treat maternal depression, post-traumatic stress disorder, and alcohol abuse, although the benefits may be smaller.
Researchers found that lower doses of primaquine are as effective as higher doses in reducing malaria transmission, and may play a crucial role in malaria elimination. The study suggests that low-dose primaquine is safe in G6PD-normal individuals and could be used to block malaria transmission.
A new study finds that high temperatures and low rainfall influence trachoma transmission in Africa, with eye-seeking flies more active at higher temperatures and abundant in areas with low rainfall. The World Health Organization aims to eliminate blinding trachoma by 2020, but understanding all factors affecting the disease is crucial.
Pursuing clean water projects and vaccination campaigns could avert up to 89,000 future cholera infections and protect against other water-borne diarrheal diseases. Improved WASH services have long-term benefits for Haiti's public health beyond ending cholera transmission.
