Accounting for biodiversity in the dairy industry.

Biodiversity is an essential part of properly functioning ecosystems, yet the loss of biodiversity currently occurs at rates unparalleled in the modern era. One of the major causes of this phenomenon is habitat loss and modification as a result of intensified agricultural practices. This paper provides a starting point for considering biodiversity within dairy production, and, although focusing primarily on the United States, findings are applicable broadly. Biodiversity definitions and assessments (e.g., indicators, tools) are proposed and reviewed. Although no single indicator or tool currently meets all the needs of comprehensive assessment, many sustainable practices are readily adoptable as ways to conserve and promote biodiversity. These practices, as well as potential funding opportunities are identified. Given the state of uncertainty in addressing the complex nature of biodiversity assessments, the adoption of generally sustainable environmental practices may be the best currently available option for protecting biodiversity on dairy lands.

Time to weigh in on obesity and associated comorbidities in combat-wounded amputees.

BACKGROUND: The Joint Trauma System database estimates that about 1,200 individuals have sustained a combat-related amputation during the Global War on Terror. Previous retrospective studies have demonstrated that combat-related amputees develop obesity and cardiovascular disease, but the incidence of obesity and associated comorbidities in this population is unknown. The objectives of this study are to determine the prevalence of obesity in the military amputee population and to compare this with the general population. METHODS: This is a retrospective review of 978 patients who sustained a combat-related amputation from 2003 to 2014. Prevalence of obesity and comorbid conditions were determined. A multivariate logistic regression model was performed to identify risk factors for postamputation obesity. Kaplan-Meier curves were constructed using obesity as the event of interest. RESULTS: A total of 1,233 charts were reviewed with 978 patients included for analysis. The median age of injury was 24 years. Median follow-up time was 8.7 years, ranging from 0.5 years to 16.9 years. The average Injury Severity Score was 23.3. The average body mass index preinjury was 25.6 kg/m2, and the average most recent corrected body mass index was found to be 31.4 kg/m2. Prevalence of comorbidities was higher in the amputee population. Fifty percent of patients who progressed to obesity did so within 1.3 years. CONCLUSION: There is a notable prevalence of obesity that develops in the amputee population that is much higher than the general population. We determined that the amputee population is at risk, and these patients should be closely monitored for 1 to 2.5 years following injury. This study provides a targeted period for which monitoring and intervention can be implemented. LEVEL OF EVIDENCE: Retrospective, basic science, outcomes analysis, level III/IV.

Accuracy of Right Upper Quadrant Ultrasound in Estimating Gallbladder Wall Thickness.

OBJECTIVE: Ultrasound (US) evaluation of biliary pathology can be influenced by a variety of factors. This study examines the effect of patient specific factors on the accuracy of sonographic evaluation of gallbladder wall thickness (GBW). METHODS: We performed a retrospective review of all patients who underwent cholecystectomy at a single institution from November 2012 to October 2015. GBW measured on US was compared with pathology results. Results were analyzed in relation to patient specific factors to include BMI, age, presence of diabetes, sex, and urgent versus elective cases. RESULTS: In total 601 patients underwent cholecystectomy, 484 of which had paired preoperative US GBW measurement and postoperative pathologic specimen measurement. No significant difference in accuracy or precision of US measurement of the GBW based on BMI was found. Accuracy was not related to age, sex, urgency, or diabetes. Precision decreased with pathologic thickening, age, male sex, and urgent case performance. CONCLUSIONS: US is accurate in measuring GB wall thickness regardless of patient specific factors. A nonsignificant trend exists with decreased precision with pathologic thickening, age, male sex, and urgently performed cases.

The One Health Approach to Toxoplasmosis: Epidemiology, Control, and Prevention Strategies.

One Health is a collaborative, interdisciplinary effort that seeks optimal health for people, animals, plants, and the environment. Toxoplasmosis, caused by Toxoplasma gondii, is an intracellular protozoan infection distributed worldwide, with a heteroxenous life cycle that practically affects all homeotherms and in which felines act as definitive reservoirs. Herein, we review the natural history of T. gondii, its transmission and impacts in humans, domestic animals, wildlife both terrestrial and aquatic, and ecosystems. The epidemiology, prevention, and control strategies are reviewed, with the objective of facilitating awareness of this disease and promoting transdisciplinary collaborations, integrative research, and capacity building among universities, government agencies, NGOs, policy makers, practicing physicians, veterinarians, and the general public.
