Pilot studies of recruitment and feasibility of remote Tai Chi in racially diverse older adults with multisite pain.

Background: Multisite musculoskeletal pain is highly prevalent among older adults yet undertreated. Studies support the promise of Tai Chi for managing pain and lowering fall risk. Since the COVID-19 pandemic, effective alternatives to classroom-based exercise programming are warranted.

Exercise interventions, physical function, and mobility after hip fracture: a systematic review and meta-analysis.

Purpose: To investigate the effects of different exercise components on physical function and mobility in adults after hip fracture.

Methods: Pubmed, Embase, Cochrane Library, Web of Science, CINAHL, and PsycINFO were searched up to March 2021. Randomized controlled trials investigating the effects of exercise interventions on physical function and mobility in adults after hip fracture were included.

Does wearing a surgical facemask or N95-respirator impair radio communication?

Purpose: This study evaluated the impact wearing a surgical facemask or N95 air purifying respirator (N95) has on radio reception.

Methods: We compared the ability of a flight crewmember and a layperson sitting in a Bell 407 crew compartment and a dispatcher sitting in a communication center to accurately record 20 randomized aviation terms transmitted over the radio by a helicopter emergency medical services (HEMS) pilot wearing a surgical facemask and six different N95s with and without the aircraft engine operating.

Results: With the aircraft engine off, all terms (100% accuracy) were correctly identified, regardless of the absence or presence of the surgical facemask or N95 studied.

A new addition to the mosquito fauna of the SUNY Oneonta Biological Field Station, Otsego County, New York.

An apparent natural introduction and establishment of a population of Anopheles walkeri into an ecological research site is documented. Likelihood of introduction by human activity is discussed.

Changes in distribution and abundance of mosquito populations in an ecological research tract over a 35-year period.

Marked changes in species and numbers of mosquitoes have occurred over a 35-year period. Changes relate to alteration of available larval development sites by beaver (Castor canadensis), variation in winter and spring precipitation, and differences in feeding behaviors.
