Background: Skin to skin care (SSC), prone (PP) and supine (SP) positions are standard positions in daily care for premature infants. Their influence on cardiorespiratory parameters and thermoregulation is discussed controversially.
Objectives: We compared SSC with PP, the recommended position for preterm infants, and SP, the safest position for term infants, and tested the hypothesis that SSC has no impact on cardiorespiratory parameters and thermoregulation.
Methods: In 18 spontaneously breathing premature infants [median gestational 28 weeks (24-32); chronological age 36 days (7-64), and weight 1,543 g (750-2,100)], heart and respiratory rate, breathing pattern, episodes of desaturation (<85 but >or=80 and <80%), oxygen saturation and rectal temperature were analyzed with polygraphy (Alice 3(R) and 3.5(R)) in a 6-hour measuring cycle of three subsequent series (120 min each in SP, SSC and PP) and compared (Wilcoxon test).
Results: During SSC, we found no increase in apneic attacks and bradycardic episodes and no difference in respiratory rate, breathing pattern, oxygen saturation, episodes and duration of desaturation compared to SP and PP. Episodes of desaturation <85 but >or=80 and <80% were more frequent in SP compared to PP (p = 0.0421 and p = 0.0319). Heart rate increased in SSC and PP compared to SP (154.86 bpm, SD 11.55, and 153.33 bpm, SD 15.95 vs. 150.25 bpm, SD 14.64; p = 0.0013 and p = 0.0346). Temperature level was not significantly higher during SSC and PP compared to SP except a rise between the start and the end of the 6-hour measuring cycle (37.05 degrees C, SD 0.2 vs. 37.30 degrees C, SD 0.3; p = 0.0436).
Conclusion: We found no significant SSC-mediated changes in quality and quantity of desaturations and in body temperature compared to PP in preterm infants.

Background: Nasal high flow (NHF) has been proposed to sustain high intensity exercise in people with COPD, but we have a poor understanding of its physiological effects in this clinical setting.
Research Question: What is the effect of NHF during exercise on dynamic respiratory muscle function and activation, cardiorespiratory parameters, endurance capacity, dyspnoea and leg fatigue as compared to control intervention.
Study Design And Methods: Randomized single-blind crossover trial including COPD patients.

With climate change, fish are facing rising temperatures, an increase in the frequency and severity of heat waves and hypoxia, sometimes concurrently. However, only limited studies have examined the combined effects of increases in temperature and hypoxia on fish physiology and survival. We measured the cardiorespiratory physiology of 12°C-acclimated Atlantic salmon when exposed acutely to normoxia [100% air saturation (sat.

Introduction: In high-altitude cities located above 2,500 m, hospitals face a concerning mortality rate of over 50% among intensive care unit (ICU) patients with acute respiratory distress syndrome (ARDS). This elevated mortality rate is largely due to the absence of altitude-specific medical protocols that consider the unique physiological adaptations of high-altitude residents to hypoxic conditions. This study addresses this critical gap by analyzing demographic, clinical, sex-specific, and preclinical data from ICUs in Bogotá, Colombia (2,650 m) and El Alto, Bolivia (4,150 m).

Study Objective: Hypertrophic cardiomyopathy (HCM) is the most common genetic myocardial disorder increasingly characterized by concomitant metabolic syndrome. Cardiac rehabilitation (CR) has been shown to improve metabolic parameters in populations with heart failure and myocardial infarction. However, there is a paucity of data on the impact of CR in the HCM population with metabolic syndrome.

Background: Interleukin-6 (IL-6) represents one of the main molecules involved in inflammatory responses, which can be altered in either patients with cognitive impairment or obstructive sleep apnea (OSA). The present study aimed to evaluate serum IL-6 levels and cognitive performance in patients with severe OSA (Apnea-Hypopnea Index - AHI >30/h).
Methods: Thirty patients with severe OSA were compared to 15 controls similar in age, sex, and Body Mass Index.
