Hazardous exposures and engineering controls in the landscaping services industry.

Landscapers are exposed to noise, carbon monoxide (CO), respirable dust, and respirable crystalline silica (RCS) generated from the tools they use. Although engineering controls are available to reduce these exposures, no previous study has evaluated chronic exposures to landscapers in different work settings and compared exposures from landscaping tools with and without engineering controls. This field study of workers in the landscaping services industry documented the occupational exposures of 80 participants at 11 varied worksites to noise, CO, respirable dust, and RCS using personal breathing zone sampling.

Real-World Antifungal Therapy Patterns Across the Continuum of Care in United States Adults with Invasive Aspergillosis.

Changes to antifungal therapy (AFT) in invasive aspergillosis (IA) may occur due to intolerance, side effects, drug interactions, or lack of response. We describe AFT change patterns in IA patients. This was a US claims data study.

Domino Partial Heart Transplantation.

Heart valve replacement in pediatric cardiothoracic surgery poses problems because conventional heart valve implants do not have the ability to grow. This mandates serial reoperations for implant exchanges until an adult size implant can fit. Partial heart transplantation eliminates these reoperations because the transplanted valves grow.

Early pregnancy diagnosis in cows using corpus luteum blood flow analysis based on colour Doppler ultrasonography and mRNA analysis.

Background: Reproductive efficiency is paramount in the dairy industry, where early pregnancy detection of dairy cows will allow to detect the non-pregnant animals early, thus enabling to re-synchronize them and getting them pregnant leading to decrease in calving interval, which, in turn, is critical for maximizing productivity and economic gain. The objective of this study was to evaluate the colour Doppler ultrasonography (CDUS) and peripheral blood leukocytes (PBLs)-based pregnancy-associated biomarker mRNAs expression for the earliest detection of pregnancy status in the dairy cows at post insemination. Intensively managed animals were ovulation synchronized and subjected to timed artificial insemination (TAI).
