Newborn babies in poor countries are missing out on routine hearing tests, leading to irreversible deficits in speech and cognitive development. A policy paper calls for increased funding for neonatal hearing tests through public-private partnerships.
A systematic review of 13 trials involving over 900 children found that loperamide should not be given to children under 3 years old or with bloody diarrhoea. However, in other children, the drug may be useful in treating acute diarrhea. The risks outweigh the benefits in high-risk situations.
The prevalence of asthma and allergic diseases has significantly increased in Ghana between 1993 and 2003. According to a study, the prevalence of exercise-induced bronchospasm and atopy doubled over this period, posing concerns for public health in West Africa.
A study of eight hospitals in Peru found that opening windows provided more than double the airflow of mechanically ventilated rooms and 18 times that of closed windows. Natural ventilation was more effective at reducing airborne infection transmission, especially in older facilities with high ceilings and large windows.
Researchers found that the poorest people in developing countries are least likely to use contraception, with significant regional variations. The authors emphasize the need for governments and international health organizations to focus on providing contraceptive services to those with very low incomes.
A 28-year study of Japanese-American men found that growing up in a large family or being born later in the family increased the risk of developing gastric adenocarcinoma. The results suggest that early-life social environment plays a significant role in microbially induced malignancies expressed decades later.
Researchers discovered that propranolol decreases erythrocyte G protein activity and inhibits blood-stage malarial parasite growth in red blood cells. The study suggests using propranolol in combination with existing antimalarials to reduce treatment doses, providing a novel antimalarial target and potential treatment strategy.
A survey in southern Sudan found a high prevalence of blindness, with 4% of the population affected. The main causes were cataract and trachoma, with trachoma being more common than expected. Trachoma can be prevented with improved living conditions, hygiene, and early treatment.
