Acute Hypercapnia at South African Abalone Farms and Its Physiological and Commercial Consequences

Fishes
Abalone Haliotis midae are distributed from the cold, hypercapnic waters of the dynamic Benguela Current Large Marine Ecosystem to the relatively warm, normocapnic waters of the Agulhas Current.

Sudden Unexpected Postnatal Collapse: A Retrospective Cohort Study Describing Incidence, Risk Factors and Role of Perinatal Transition

Acta Paediatrica, EarlyView.
ABSTRACT Aim This study aimed to investigate the incidence, risk factors and possible aetiology of sudden unexpected postnatal collapse (SUPC), a potentially fatal yet poorly understood event. Methods In a retrospective cohort, patient records from 483 284 infants born in Stockholm, Sweden, between 2002 and 2022 were screened for SUPC‐related diagnoses.

Machine learning–enhanced preoperative assessment of spontaneous ventilation risk in diverse video-assisted thoracoscopic surgeriesCentral MessagePerspective

JTCVS Open
Objectives: Despite its widespread use, spontaneous ventilation can lead to intraoperative hypoxemia or hypercapnia. In this retrospective study, we developed and validated a preoperative clinical data-based model to predict intraoperative hypoxemia or ...

Impact of Respiratory Support Strategies on CO2 Variability During Therapeutic Hypothermia in Neonates With Asphyxia: Data From the German Hypothermia Registry

Acta Paediatrica, EarlyView.
ABSTRACT Aim To evaluate associations between respiratory support strategies, partial pressure of carbon dioxide (pCO2) variability and oxygen exposure in neonates with hypoxic–ischaemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). Methods This retrospective multicentre study used data from the German Hypothermia Registry, including ...

Long-term DNA methylation changes induced by age and elevated CO2 in skeletal muscle

Skeletal Muscle
Background Skeletal muscle dysfunction and elevated CO2 in the blood, or hypercapnia, are both associated with higher mortality in acute and chronic pulmonary diseases.

Int Immunopharmacol [PDF]

Hypercapnia is known to have immunoregulatory effects within the lung. Cell culture systems demonstrate this in both macrophages and alveolar cell lines, suggesting that the alveoli are affected by changes in CO2 levels.

Cholinergic inputs to motoneurons in the spinal cord augment focal muscle spasticity in rodents

British Journal of Pharmacology, EarlyView.
Background and Purpose Cholinergic premotor inputs to motoneurons support high levels of motor output when required. However, the possible role of these inputs in pathologically elevated muscle tone has not been characterised. To address this, we examined the modulatory effect of spinal acetylcholine (ACh) on experimental spastic paralysis ...

The effects of acute hypercapnia on cerebral indole amine metabolism

, 1978
The effects of 1-h exposure to hypercapnia ([Formula: see text], 90–110 mmHg) on cerebral indole amine metabolism were studied in rats by measurement of cerebral hemisphere contents of tryptophan, 5-hydroxytryptophan (5-HTP), 5-hydroxytryptamine (5-HT),

Anaesthetic management of a horse with acute kidney injury

Equine Veterinary Education, EarlyView.
Summary Anaesthetic management of animals with acute kidney injuries (AKI) is complex and poses considerable risk. There are no publications describing management of anaesthetised horses with AKI. Perioperative and anaesthetic care of a Thoroughbred filly presented with traumatic injuries and subsequent AKI is described.
