The results of this controlled epidemiological investigation indicate that volume of vigorous physical training may be an etiologic factor for exercise-related injuries. The findings also suggest that type of training, particularly running, and abrupt increases in training volume may further contribute to injury risk.

The T-TPQ is a construct-valid instrument for measuring perceptions of teamwork. This has beneficial implications for patient safety and future research that studies medical teamwork.

OBJECTIVE:To assess the access to tuberculosis treatment in healthcare services with Programa Saúde da Família (PSF -Family Health Program) and at a reference outpatient clinic. METHODS:A descriptive inquiry was carried out in 2007 with 106 patients who received tuberculosis treatment through the PSF or the reference outpatient clinic in Campina Grande, Northeastern Brazil, from July 2006 to August 2007. To assess the health services, the instrument Primary Care Assessment Tool was used, validated and adapted to assess tuberculosis care in Brazil. The main variables analyzed referred to the transportation and distance to the service and patients' supervision. RESULTS:Of the 106 patients, 83.9% performed self-administered treatment and 16.0% received supervised treatment. The indicators from the PSF units and from the reference outpatient clinic that were similar (p>0.05) were: 65.1% "losing half work day to attend the medical visit"; 65.0% "having to use motorized transport"; 50.0% "always having to pay for motorized transport"; and 69.0% "not receiving treatment at healthcare units near home". The indicators "using motorized transport", "paying for transport to attend the medical visit" and "receiving treatment near home" were statistically different (p<0.05) between the services. Standardized and non-standardized Cronbach's alpha coefficients were, respectively, 0.7275 and 0.7075, based on the eight items of the questionnaire. CONCLUSIONS:Although the city has 85 PSF teams, supervised treatment was carried out by few health workers. Although the tuberculosis treatment is offered by the public health service, it still represents a cost to the patients, due to the distance to the healthcare service and losing half work day in order to attend medical visits.

Among a population of randomly selected US Marine Corps recruits at Marine Corps Recruit Depot, San Diego, California, the authors developed a screening tool to identify individuals at high risk for lower extremity stress fracture when beginning a rigorous physical training program. The screening tool was developed among 1,286 recruits, then tested and refined among 1,078 additional recruits. The refined algorithm, consisting of five physical activity questions and a 1.5-mi (2.4-km) run time, revealed that 21.6% of "high risk" subjects suffered more than three times as many stress fractures as "low risk" subjects. These data suggest that risk of stress fracture during rigorous physical training is increased by poor physical fitness and low levels of physical activity prior to their entry into the program.
