The study used a new approach to investigate chromosome imbalances in early-stage cancers, with patients experiencing varying disease-free survival rates based on their tumour balance.
Researchers investigate genetic link between Prader-Willi syndrome and psychotic illness, finding association with a sex-specific imprinted gene on chromosome 15. The study suggests that allelic variation of this gene could be a cause of genetic vulnerability to psychotic illness in the general population.
Child malnutrition rates are 50% in some conflict areas, while vaccine-preventable diseases persist due to the ongoing war. Militia groups regularly direct armed raids against Dinka villages, resulting in deaths and disappearances of family members, particularly children under 5 years old.
A comprehensive UK study highlights the risk factor of high staff workload on infant mortality in intensive care units. After adjusting for initial clinical risk and illness severity, patient volume and staffing provision did not influence mortality or cerebral-damage outcomes.

Smoking cessation or reduction leads to fewer wound-related and cardiovascular complications, with a significant decrease in hospital stay duration.
A prospective population study found that HIV-1-positive women are 16 times more likely to develop vulvovaginal or perianal lesions than HIV-1-negative women. The study suggests that HIV-1-positive women should have a thorough inspection of the vulva and perianal region during gynaecological examination.

A study of 344 cardiac patients who experienced a near-death experience (NDE) after cardiac arrest found that younger patients were more likely to report NDEs, while deeper experiences were more common among women. Longitudinal follow-up revealed increased beliefs in an afterlife and reduced fear of death among those with NDEs.
Researchers found that apolipoprotein B and A-I were strongly linked to increased risk of fatal heart attack in both men and women. Higher concentrations of ApoA-I had a protective effect, suggesting apolipoproteins may be valuable for diagnosis and treatment.
