We present extremity wound microbiology data from 250 combat casualties (2009-2012). Confirmed extremity wound infections (EWIs) were based on clinical and laboratory findings. Suspected EWIs had isolation of organisms from wound cultures with associated signs/symptoms not meeting clinical diagnostic criteria.

Article Synopsis
  • - The Trauma Infectious Disease Outcomes Study (TIDOS) tracked military personnel with injuries from combat between June 2009 and May 2012 to assess their short- and long-term infectious complications, finding that over 30% experienced infections during initial hospitalization.
  • - Out of 1,006 patients studied, 35% had infections during hospitalization, and 45% of those developed further trauma-related infections after discharge, indicating a notable risk linked to initial infections.
  • - Factors such as sustaining an amputation, having more infections initially, and specific antibiotic use increased the likelihood of developing subsequent infections, while shorter hospital stays seemed to reduce that risk.

Purpose: Guideline implementation in primary care has proven difficult. Although external assistance through performance feedback, academic detailing, practice facilitation (PF), and learning collaboratives seems to help, the best combination of interventions has not been determined.

Methods: In a cluster randomized trial, we compared the independent and combined effectiveness of PF and local learning collaboratives (LLCs), combined with performance feedback and academic detailing, with performance feedback and academic detailing alone on implementation of the National Heart, Lung and Blood Institute's Asthma Guidelines.

Background: This study evaluated a wide range of viral load (VL) thresholds to identify a cut-point that best predicts new clinical events in children on stable highly active antiretroviral therapy (HAART).

Methods: Cox proportional hazards modeling was used to assess the adjusted risk for World Health Organization stage 3 or 4 clinical events (WHO events) as a function of time-varying CD4, VL, and hemoglobin values in a cohort study of Latin American children on HAART ≥6 months. Models were fit using different VL cut-points between 400 and 50,000 copies per milliliter, with model fit evaluated on the basis of the minimum Akaike information criterion value, a standard model fit statistic.

Article Synopsis
  • - The study analyzed the link between maternal use of antiretrovirals (ARVs) during pregnancy and congenital anomalies (CAs) in infants, using data from a perinatal study involving women from Argentina and Brazil.
  • - Out of 1229 women, 995 pregnancy outcomes were assessed, revealing that 60 infants had at least one CA, leading to a prevalence rate of 6.2 per 100 live births.
  • - Findings indicated that the prevalence of CAs was similar regardless of ARV exposure during the first, second, or third trimesters, suggesting the need for ongoing monitoring of infants exposed to ARVs in utero.

The prevalence of antibodies to measles, mumps, and rubella in US military recruits is of importance to public health leaders. We performed ELISA testing using a commercially available product on samples from 537 recruits obtained in 1998, of which 437 were positive (81%). We then performed a validation study in a subsample of the population using plaque reduction neutralization (PRN) to assess misclassification error.

A retrospective cohort study was conducted to evaluate the Department of Defense practice of allowing some individuals with a history of attention-deficit/hyperactivity disorder (ADHD) to enter military service (waiving for ADHD). Enlisted recruits who entered active duty with a waiver for academic problems related to ADHD were compared with control subjects who did not reveal health problems before entry, in terms of retention, promotion, and mental health-related outcomes. A total of 539 recruits with a history of ADHD were retained at the same rate as 1,617 control subjects, with no differences in promotion rates, comorbid diagnoses, or mental health-related discharges.
