Outcomes From a Physician Health Center.

This retrospective cohort study describes the population of physicians seeking medical evaluation in a dedicated physician health center and identifies factors associated with needing practice restrictions. Participants had an initial evaluation between January 1, 2016, and December 31, 2022. We report personal and professional demographics and types of medical conditions in this cohort. An ordinal logistic regression analysis was used to identify factors associated with occupational outcomes. Physicians in a wide variety of specialties from 34 different states presented for evaluation of diverse medical problems. More than half of the participants presented with occupational concerns. The presence of a neurologic or psychiatric illness were the only factors associated with temporary or permanent restrictions. Physicians with medical conditions impacting their ability to practice have a professional obligation to obtain a thorough, objective medical evaluation. Such evaluations should support and protect patients, employers, and the physicians themselves.

COVID-19 Pandemic Effects on the Well-Being of Professional Pilots.

OBJECTIVE: The aim was to evaluate the well-being of professional pilots using a survey that included the World Health Organization (WHO)-5 Well-Being Index.METHODS: An electronic survey was sent to pilots between June 17-August 2, 2021. Pilots self-categorized as: airline transport pilot (ATP), commercial pilot, or both. Chi-squared and Fisher's exact tests were used to evaluate differences between variables. Logistic regression was used to estimate the odds of impaired well-being.RESULTS: A total of 639 individuals returned the survey. The majority of respondents were ATPs and a majority identified as male. The average well-being score was 68.0 out of 100 possible, with 22% of respondents meeting the threshold definition of impaired well-being. The odds of having impaired well-being were not dependent on gender. In unadjusted analysis, the odds of impaired well-being were higher for those flying as commercial pilots as compared to airline transport pilots/both. Age was also strongly associated with impaired well-being, with younger pilots having greater odds of impaired well-being as compared to older pilots. Only a little over half of the surveyed pilots agreed or strongly agreed that pilot risk of occupational exposure to COVID-19 was appropriately controlled.CONCLUSION: This survey suggests an important connection between pilot age and impaired well-being scores during the COVID-19 pandemic. Future studies targeting the well-being of younger pilots will be of interest. Additionally, measures to reduce occupational risk of COVID-19 exposure may be helpful in view of the substantial fraction of pilots expressing concern regarding that risk.Stratton E, Haddon R, Murad MH, Petterson T, Nelson M, Cowl CT.

Quantitative Evaluation of Tactile Foraging Behavior in Pekin and Muscovy Ducks.

Ducks have developed a variety of foraging strategies that utilize touch sensitive bills to match their ecological niche within wetlands. These techniques include diving, sieving, dabbling, and grazing. Ducks exhibiting tactile specialization in foraging outperform visual and non-tactile foraging ducks in behavioral experiments and have a higher percentage of light-touch mechanoreceptor neurons expressing Piezo2 in the trigeminal ganglia. Belonging to two different tribes of Anseriformes, the well-studied tactile specialist Pekin (Tribe Anatini: Anas platyrhynchos domestica) and lesser studied Muscovy (Tribe Cairinini: Cairina moschata domestica) ducks were tested on a series of experiments to assess these birds' functional tactile acuity. Both species of duck were able to separate out and consume edible items from increasing amounts of inedible plastiline clay distractors. They could also both be trained to associate a food reward with plastiline stimuli of differing size and shape using touch alone. However, only females of each species could learn to associate food reward with otherwise identical stimuli differing only in hardness. Pekin females performed significantly better than Muscovy females suggesting the anatomical specializations present in many Anatini may contribute to this type of tactile acuity. These findings have potential relevance in understanding the evolution of tactile ability and feeding ecology.
