A population-based study found that women with breast cancer are more likely to be absent from work for 4 weeks or more compared to healthy women. However, by the third year, work absence patterns become similar. The study also reveals factors that modulate work absence, such as stable relationships and self-employment.
Researchers at University of Illinois Chicago have found a new connection between the signaling protein Raf Kinase Inhibitor Protein (RKIP) and cell migration. By studying the compound locostatin, they identified RKIP as a key player in controlling cell movement, suggesting it as a potential target for anti-cancer strategies.
Countries like Finland and the Netherlands have successfully controlled MRSA through strict screening, contact precautions, and rapid identification of cases. In contrast, Japan's lack of a mechanism to identify patients within hospitals has led to high MRSA incidence rates worldwide.
A study tracking 43,000 men and women found that light smoking (1-4 cigarettes/day) significantly increases the risk of coronary artery disease and lung cancer. Women are almost five times as likely to die from lung cancer compared to non-smokers.
Researchers used molecular epidemiologic methods to identify the relationships between four separate foodborne hepatitis A virus outbreaks in Tennessee, North Carolina, Georgia, and Pennsylvania.

Commonly used disease models may make overly optimistic predictions about the levels of public health interventions needed. Researchers found that ignoring the latent period or assuming unrealistic distributions can result in underestimating transmission potential. The study emphasizes the need to consider these factors when making qua...
A study of 106 postmenopausal women found that alveolar bone loss is the strongest predictor of tooth loss in this population. The risk of tooth loss increases by 3 times for each millimeter of alveolar bone loss and 2.5 times for each millimeter of clinical attachment loss.
A growing appetite for public reporting of hospital infection rates could lead to improved patient safety and quality of care. UT Southwestern professor Dr. Jane Siegel advocates for standardized reporting systems to track key metrics, but notes that challenges exist due to differences in patient populations and data collection methods.
A new study published in Virology suggests that some strains of monkeypox are more virulent than others, depending on their origin in Africa. The 2003 US outbreak was caused by a West African virus, which may have been less deadly due to its strain.

The study aims to develop new methods of mosquito control to prevent resistance.
A retrospective cohort study of 198 children who underwent fundoplication at Texas Children's Hospital from 1996-1999 found that fundoplication is not a long-term solution for treating GERD in children. Alternative medical treatments, such as histamine-2 receptor antagonists and proton pump inhibitors, are recommended instead.
Researchers aim to understand why some generations exhibit higher rates of violence in adolescents, using data from the Pittsburgh Youth Study. The study will examine age groups and potential cultural or economic factors influencing violence.

A study published in PLOS Medicine found that supervised treatment interruptions, which aim to boost natural immunity by briefly exposing patients to low levels of the virus, are ineffective in controlling HIV-1 viremia. Researchers were able to achieve transient control of the virus in some patients, but it was not sustained over time.
Studies examining prehypertension reveal a significant increase in heart disease and stroke risks among affected individuals. Prehypertension is associated with unfavorable levels of other major cardiovascular disease risk factors and contributes to a substantial burden on the healthcare system.

Over 30 years of follow-up, Vietnam veterans experienced a 7% higher death rate from external causes, including motor vehicle collisions, suicides, and homicides. This excess mortality was limited to the first five years after discharge, but also included higher mortality rates from unintentional poisonings and drug-related deaths.
A randomized controlled trial found that patients referred to an alcohol-health worker after visiting the emergency department consumed significantly less alcohol over six months. This intervention reduced reattendance at emergency departments by 0.5 visits on average per year.
Researchers, led by Dr. Shelagh Campbell, study ATM mutants to understand the molecular mechanisms behind A-T disease. They found that mutant males exhibited locomotor defects, sensitivity to ionizing radiation, and chromosome instability similar to those seen in human patients.
