Molecular and Cellular Investigations of Prader-Willi Syndrome
… Obesity with Hypothalamic Dysregulation, Hypoventilation, and Autonomic Dysfunction (ROHHAD) and Congenital Central Hypoventilation syndrome (CCHS). ROHHAD presents with several key similarities to PWS including rapid-onset obesity and hypothalamic dysfunction. In this study, we found six …

Comparison of Two Aerosolized Bronchodilators in the Treatment of Severe Equine Chronic Obstructive Pulmonary Disease
… pulmonary gas exchange, indicative of alveolar hypoventilation, VA/Q mismatching and diffusion impairment. Ipratropium treatment significantly (p< 0.05) reduced arterial CO₂ tension and end-tidal CO₂ tension toward normal, but significantly increased p(A-a)O₂ from baseline. The change in paCO₂ …

Contributors to processing speed deficit in old age: A focus on history of obesity and medical conditions
… adipokines, low grade inflammation, chronic mild hypoventilation) are present even among the otherwise healthy obese population, and it is possible that many of these factors have differential impact on cognition according to magnitude and duration of exposure. Knowledge of a person’s weight …

Using Next-Generation Sequencing to Identify Genes Mutated in Human Disorders
… The first is ROHHAD (Rapid-Onset Obesity with Hypoventilation, Hypothalamic Dysfunction and Autonomic Dysregulation), a rare, complex, and potentially fatal pediatric syndrome. The second is DTD (Developmental Topographical Disorientation), a novel behavioural phenotype in which individuals are …

Peri-extubation practices and extubation failure in a South African tertiary paediatric intensive care unit
… heart failure (n=3; 14.3%); diaphragm paralysis, hypoventilation and cardiac arrest (n=2; 9.5% each); and reduced level of consciousness (n=1; 4.8%). Prematurity (adjusted OR 1.8 (95% CI 0.05 – 0.6); p =0.004), dysmorphology (OR 1.8 (95% CI 0.05 – 0.6); p=0.022), decreased level of consciousness …

Modeling Post Stroke Respiratory Dysfunction, Apneas and Cognitive Decline
… characterized by incidences of apnea and hypoventilation. Interestingly, mice with high incidence of apneas display signs of progressive cognitive decline compared to those with low/no incidence of apneas. Histological analysis of vital brainstem respiratory control sites unveiled reactive …

Psychophysiological Effects of Respiratory Challenges before and after Breathing Training in Panic Disorder and Patients suffering from Episodic Anxiety Attacks
… underwent in randomized order a Voluntary Hypoventilation (VHO) test and a Voluntary Hyperventilation (VHT) test in which they were asked to either lower or raise their pCO2 while psychophysiological measures were recorded. Each test consisted of 3 segments: 1 min baseline, 3 min paced …

Low-dose thiafentanil in combination with azaperone alone or azaperone and medetomidine for the immobilization of African buffalo (Syncerus caffer)
… decreased pulmonary oxygen diffusion rather than hypoventilation. Importantly, despite respiratory rates and partial pressure of carbon dioxide (PaCO2) values being within the normal expected physiological range, hypoxaemia was more severe in the TMA combination. Supplementary oxygen is considered …

Cerebrovascular and respiratory adaptations following 4 weeks of transient hypercapnic aerobic exercise.
Background: Utilizing nasal breathing (NB) during a moderate-intensity aerobic exercise bout can elicit a hypercapnic insult that increases cerebral blood flow (CBF) and oxygen mobilization. Therefore, NB may bestow unique cerebrovascular and pulmonary adaptations. Aims: To examine if utilizing NB …

The epidemiology of hypercapnic respiratory failure
Hypercapnic respiratory failure is a condition that is encountered commonly by many clinicians. It can occur in association with a range of respiratory, cardiovascular, metabolic and neurological disorders, either alone or in combination. Most of the current literature is limited to case series …
