Seven late-breaking clinical trials presented at ATS 2012 examined treatments for ventilator-associated pneumonia, cardiac surgery associated kidney injury, septic shock, idiopathic pulmonary fibrosis, smoking cessation, malignant pleural effusion, and non-cystic fibrosis bronchiectasis. Results showed that shorter courses of doripenem...
Researchers found that primary care-based management was comparable to specialist care in terms of ESS scores, FOSQ scores, and CPAP compliance. Home auto-titrating CPAP usage was also similar between the two groups. The study suggests a lower-cost alternative for OSA treatment, particularly beneficial for rural and remote regions.
A new study published in Science found that workplace safety inspections conducted by California's Division of Occupational Safety and Health (Cal/OSHA) reduce on-the-job injuries and their associated costs, with no negative impact on companies' performance or profits. The researchers examined the effects of randomized inspections on w...
A study examining registered clinical trials found that many small, single-center trials were submitted between 2007-2010, leading to heterogeneity in methodological approaches. The majority of trials had an anticipated enrollment of 1,000 or fewer participants, and only 44% were funded by industry.
A study published in PLOS Medicine found that immediate induction of labor does not significantly improve pregnancy outcomes for women with preterm prelabor rupture of membranes. Instead, expectant management is recommended to reduce the risk of maternal infection and neonatal sepsis.
A randomized trial found IPTi to be an effective preventive measure against malaria episodes in infants exposed to both falciparum and vivax malaria. The study showed a significant reduction in malaria cases with regular IPTi treatment during infancy.
Researchers found that patients who received early temporary treatment with antiretroviral drugs (cART) for 24 weeks had a lower viral setpoint and delayed the need to restart treatment during chronic HIV infection. This delay lasted for an average of 0.7 years, compared to those who did not receive early cART.
