Background: When coronavirus disease 2019 (COVID-19) mitigation efforts waned, viral respiratory infections (VRIs) surged, potentially increasing the risk of postviral invasive bacterial infections (IBIs). We sought to evaluate the change in epidemiology and relationships between specific VRIs and IBIs [complicated pneumonia, complicated sinusitis and invasive group A streptococcus (iGAS)] over time using the National COVID Cohort Collaborative (N3C) dataset.
Methods: We performed a secondary analysis of all prospectively collected pediatric (<19 years old) and adult encounters at 58 N3C institutions, stratified by era: pre-pandemic (January 1, 2018, to February 28, 2020) versus pandemic (March 1, 2020, to June 1, 2023).

Purpose: This study aimed to analyze the competitive demands of mountain running races of varying lengths.
Methods: Sixty-six male athletes competed in Vertical race (∼3 km and ∼1000 m of total elevation change), Sky race (∼25 km and ∼3000 m of total elevation change), and SkyUltra race (∼80 km and ∼9000 m of total elevation change). Exercise intensity and competition load (TL) were assessed using running power, heart rate, and rating of perceived exertion (RPE).

Purpose: The present study investigated the effect of unpleasant salty or bitter tastes on cycling sprint performance and knee-extensor force characteristics in different fatigue states.
Methods: Following a familiarization session, 11 trained male cyclists completed 3 experimental trials (salty, bitter, and water) in a randomized crossover order. In each trial, participants cycled at 85% of the respiratory compensation point for 45 minutes and then, after a 5-minute rest, completed a 1-minute sprint.

Objective: To analyze the results of nocturnal breathing parameters during sleep based on nocturnal pulse oximetry and to study of characteristics of external respiration in genetically confirmed patients with dystrophic myotonia (DM).
Material And Methods: The subjects of the study were patients with genetically confirmed DM types 1 and 2 who were hospitalized in the neurological departments of the Republican Scientific and Practical Center for Neurology and Neurosurgery. The clinical picture of the disease, comorbidities, sleep questionnaires, laboratory tests, overnight pulse oximetry and spirometry were performed and analyzed.
The clinical manifestations of SARS-CoV-2 infection may range from asymptomatic or minor conditions to severe and life-threatening outcomes. The respiratory system is a principal target of the virus and in the majority of cases of severe disease, an acute form of pneumonia develops. Despite concerted global efforts to elucidate the pathogenic mechanisms of COVID-19, the progression of the infection leading to pulmonary damage remains poorly understood.
