Resilience is a psychometric construct of a patient's ability to recover from adversity and has been used to predict outcomes but its use in orthopedics has been limited. The purpose of this study was to examine the association between resilience and outcomes. ⋯ Active-military patients with high preoperative resilience appear to have significantly better early postoperative outcomes following sports knee surgery in terms of PROMIS-43, KOOS, and IKDC. There was also a lower rate of changing MOS secondary to sports knee surgery in patients with high resilience.

Prevalence of Lyme Disease Attributable to Military Service at the USMA, West Point NY: FY2016-2018.
Lyme disease incidence rates have steadily increased since its official recognition in 1975. Since exposure to Lyme is associated with activities conducted in and around tick-habitats including tall grass, shrubs, deciduous forest, and leaf litter, it has been suggested that service members, who are thought to spend higher amounts of time in these habitats due to training requirements, may have higher risk for exposure. Specifically, this study looks at service member and family member exposure to Ixodes scapularis, the vector for Lyme in the Northeastern and Midwestern United States. While literature pertaining to occupational and military specific exposures to Lyme vectors have attempted to quantify the possible elevated risk of Lyme disease for service members, thus far, studies have not consistently confirmed that service members are at a greater risk than family members. ⋯ While this study was unable to capture the military specific occupational exposure to I. scapularis, it does show a difference in period prevalence between service members and family members with the family members being at higher risk to contract Lyme instead of service members as is commonly suggested in the literature. Additional studies may be conducted to see if this holds true across service member Military Occupational Specialties as a proxy for occupational exposure. Similar studies should be conducted at military installations situated in Lyme endemic areas to determine if these results are comparable across the military or specific to West Point. Future research should attempt to identify all the service member protective factors against Lyme with attribution to permethrin-treated uniforms and other military interventions designed to defend soldiers against vector-borne diseases.

Carbon monoxide (CO) is produced from incomplete combustion of hydrocarbons and is a by-product of tobacco smoking. Chronic cigarette smokers often have carboxyhemoglobin (COHb) concentrations as high as 10%. We report a case of severely elevated COHb and polycythemia because of tobacco smoking and provide a review of the literature regarding elevated COHb in smokers. ⋯ Many active duty military and military veterans are tobacco smokers and these patients and their health care providers should be aware of the adverse effects of CO toxicity from tobacco smoking. Patients may have symptoms such as headaches, syncope, and ataxia in the setting of acute CO toxicity; however, the chronic effects of CO may not be completely understood. Future work could explore chronic CO toxicity and its effects on strength and exercise tolerance in military personnel and provide education to service members, veterans, and health care providers.

There is mixed evidence regarding how posttraumatic stress disorder (PTSD) symptom clusters are associated with sexual dysfunction (SD), and most studies to date have failed to account for potentially confounding variables. Our study sought to explore the unique contribution of PTSD symptom clusters on (a) lack of sexual desire or pleasure, and (b) pain or problems during sexual intercourse, after adjusting for comorbidities and medication usage. ⋯ Sexual dysfunction is prevalent among male treatment-seeking CAF personnel and veterans. Results suggest that PTSD symptoms are differentially associated with sexual desire or pleasure concerns. Assessing sexual function among CAF personnel and veterans seeking treatment for PTSD is critical in order to treat both conditions and improve overall functioning.

Severe upper limb injuries (SULI) may pose a significant public health challenge for the military; however, SULI has not been previously defined or studied in the US military. Objective: Determine SULI incidence, risk factors, and outcomes. ⋯ The study findings provide preliminary evidence on the incidence, natural history and distribution of SULI in this population. The findings indicate SULI may impact readiness and result in premature military separation.
