VA’s new “burden-free” study method finds two blood pressure drugs equally effective

A large VA clinical trial found that chlorthalidone (CTD) was not superior to hydrochlorothiazide (HCTZ) for preventing cardiovascular disease or non-cancer death. The study enrolled over 13,500 Veterans with high blood pressure and showed no difference between the two drugs in terms of effectiveness.

Which COVID-19 vaccine works better?

The study found that the Moderna vaccine offered a lower risk of documented infection (21% reduced), symptomatic COVID-19 (44% reduced), hospitalization (55% reduced), ICU admission (10% reduced), and death (2% reduced) compared to the Pfizer vaccine. The results suggest that either vaccine is effective, but Moderna may be slightly mor...

Study sheds light on interplay among PTSD, combat experience, alcohol use

A recent study found that combat experience is associated with a higher risk of alcohol use to cope with PTSD symptoms, but this link weakens when adjusting for PTSD severity. The study also reveals that trauma-exposed men without combat experience are more likely than those with combat experience to report an alcohol use disorder.

Brain area tied to emotions is larger in vets, service members with mild TBI and PTSD

A new study found that veterans and active-duty service members with combat-related PTSD and mild traumatic brain injury had larger amygdalas, a key region in processing emotions, compared to those with only brain injuries. The findings suggest a potential link between amygdala size and the development of PTSD symptoms.
