Meta Analysis
Reproducibility of Maximum Respiratory Pressure Assessment: A Systematic Review and Metanalysis.
Accurate assessment of maximum respiratory pressure is vital when tracking disease progression and devising treatment strategies. Previous studies indicate a learning effect when undertaking maximum respiratory pressure measurements. The extent of this learning effect and methodologies undertaken to mitigate this learning effect have not been investigated systematically. ⋯ Inspiratory muscles warm-up procedures induce higher increases in maximum inspiratory pressure in comparison with single and repeated testing sessions of maximum respiratory pressure in healthy individuals. Warm-up protocols are more effective to obtain the maximum performance of inspiratory muscles in one testing session in comparison with other methods.

Multicenter Study
Early recognition of low-risk SARS-CoV-2 pneumonia: A model validated with initial data and IDSA/ATS minor criteria.
A shortage of beds in ICUs and conventional wards during the COVID-19 pandemic led to a collapse of health care resources. ⋯ Initial biochemical findings and the application of < 3 IDSA/ATS minor criteria make early identification of low-risk SARS-CoV-2 pneumonia (approximately 80% of hospitalized patients) feasible. This scenario could facilitate and streamline health care resource allocation for patients with COVID-19.

The narrative of the rise and fall of the stethoscope is partly written. Medical historians agree on the rise in its use; however, on the decline, they are less certain. ⋯ Primary sources include medical school curricula, books, medical journals, and popular literature. Trends and projections in patent applications for stethoscope modifications and sales of the instrument provide additional evidence for the robust position of the stethoscope in current American practice.
