BACKGROUND Streptococcus pneumoniae is an uncommon but serious cause of infective endocarditis (IE), particularly in immunocompromised individuals, such as those with untreated HIV. When pneumococcal IE occurs, it is associated with high morbidity and mortality due to the high prevenance of complications such as acute valvular destruction and septic embolization. Therefore, early recognition and prompt surgical intervention are paramount to improving outcomes.

Background: The present study examined the effect of a training program with or without equipment on 1000-m surface combat swimming and shooting ability.

Methods: The study included 45 officer cadets who were randomly assigned to one of three groups: a control group (CG), a swimsuit and fins group (SF), and a combat uniform and equipment group (UE). SF and UE followed a 60-min surface combat swimming (sCS) training program for 4 weeks.

Military and law enforcement members' shooting ability is influenced by their postural balance, which affects their performance and survivability. This study aimed to investigate the effects of a proprioception training program (standing or walking on unstable surfaces) on postural balance and shooting performance. Twenty participants, divided into two groups, completed 60 shots in a shooting simulator while standing, before and after a 4-week proprioception training program.
