Background: Accurate assessment of oxygen delivery relative to oxygen demand is crucial in the care of a critically ill patient. The central venous oxygen saturation (Svo) enables an estimate of cardiac output yet obtaining these clinical data requires invasive procedures and repeated blood sampling. Interpretation remains subjective and vulnerable to error.

Introduction: Idiopathic intracranial hypertension (IIH) is known to elevate cardiovascular disease (CVD) risk, but the extent to which obesity and IIH-specific factors contribute to this risk is not well understood. WE aim to separate the effects of obesity from IIH-specific factors on the risk of stroke and CVD, building on previous findings that indicate a two-fold increase in cardiovascular events in women with IIH compared to BMI-matched controls.

Methods: An obesity-adjusted risk analysis was conducted using Indirect Standardization based on data from a cohort study by Adderley et al.

Objective: The psychiatric disorders among healthy carriers of hepatitis B (HBsAg), who have no severe physical disability or any medical treatment, have clinical importance. We aimed to research the comorbid psychiatric disorders and alexithymia and to identify whether alexithymia and accompanying somatic symptoms predict the presence of psychiatric diagnoses or not among HBsAg carriers.

Methods Eighty-nine: healthy carriers of Hepatitis B patients and nınety-three healthy individuals were included to study.

Unlabelled: Blue carbon represents the organic carbon retained in marine coastal ecosystems. (an Arabic for "mudflats"), formed in tidal environments under arid conditions, have been proposed to be capable of carbon sequestrating. Despite the growing understanding of the critical role of blue carbon ecosystems, there is a current dispute about whether sabkhas around the Persian Gulf can contribute to carbon retention as a blue carbon ecosystem.

Naturally occurring peptides display a wide mass distribution after ionization due to the presence of heavy isotopes of C, H, N, O, and S and hydrogen loss. There is a crucial need for sensitive methods that collect as much information as possible about all plasma peptide forms. Statistical analysis of the delta mass distribution of peptide precursors from MS/MS spectra that were matched to 63,077 peptide sequences by X!TANDEM revealed Gaussian peaks representing heavy isotopes and hydrogen loss at integer delta mass values of -3, -2, -1, 0, +1, +2, +3, +4, and +5 Da.

Alpha and Theta Oscillations Associated With Behavioral Phenotypes of Pain-Attention Interaction.

Brain Behav

January 2025

Division of Brain, Imaging and Behavior, Krembil Brain Institute, Krembil Research Institute, University Health Network, Toronto, Ontario, Canada.

Purpose: Pain is inherently salient and so draws our attention in addition to impacting performance on attention-demanding tasks. Individual variability in pain-attention interactions can be assessed by two kinds of behavioral phenotypes that quantify how individuals prioritize pain versus attentional needs. The intrinsic attention to pain (IAP) measure quantifies the degree to which a person attends to pain (high-IAP) or mind-wanders away from pain (low-IAP).

Background: Anti-aging facial procedures with nonenergy and nonablative energy devices are increasingly popular among patients with skin of color (SOC). Algorithms have addressed the measures to reduce the side effects related to aesthetic procedures, but few focus on SOC patients and periprocedural integrating skincare.

Methods: Eight dermatologists from Brazil, Canada, South Africa, Mexico, and the USA participated in a meeting and an online follow-up to develop an algorithm for periprocedural skincare for nonenergy and nonablative energy-based facial aesthetic procedures in patients with SOC.

Glucagon-like peptides agonists promote maturation of intestinal organoids derived from neonates with necrotizing enterocolitis.

Pediatr Surg Int

January 2025

Department of General and Thoracic Surgery, The Hospital for Sick Children, University of Toronto, 1526-555 University Ave, Toronto, ON, M5G 1X8, Canada.

Purpose: Necrotizing enterocolitis (NEC) majorly affects premature infants, causing not only necrosis and inflammation but also feeding intolerance and gastrointestinal dysmotility, hinting at gut hormone secretion impairment. Particularly critical is the gestation period before 26 weeks where intestinal hormonal activity is partially developed, rendering preterm neonates highly susceptible to NEC. Emerging evidence suggests a role of gut hormones, especially glucagon-like peptides (GLP) in ileum development.

Several jurisdictions have implemented legalization policies for non-medical cannabis, mainly towards improving public health and reducing illegal cannabis markets and crime. As some legalization initiatives are approaching maturity, conducting policy impact assessments has become timely. Emerging data, however, suggest rather mixed pictures for key outcomes and indicators.

Neurosci Biobehav Rev

January 2025

Department of Psychiatry, University of Toronto, ON, Canada; Centre for Addiction and Mental Health, Toronto, ON, Canada; Cundill Centre for Child and Youth Depression, Toronto, ON, Canada.

Psychiatric conditions can affect the experience of pain. Several reports indicate that Major Depressive Disorder (MDD) is associated with an increased pain threshold, while Anxiety Disorders (ADs) may amplify the perception of pain. However, available data on the nociceptive threshold in these psychiatric conditions are controversial.

The Roles of Cannabis Potency and Gender in Cannabis Dependence and Anxiety in Recent Cannabis Users with Trauma Exposure Histories.

Pharmacol Res

January 2025

Department of Psychiatry, Dalhousie University, 5909 Veterans' Memorial Lane, 8th Floor, Abbie J. Lane Memorial Building, QEII Health Sciences Centre, Halifax, NS, B3H 2E2, Canada.

Over the past 20 years, levels of Δ9-tetrahydrocannabinol (THC) in cannabis have significantly increased, while levels of cannabidiol (CBD) have increased much less in comparison. Cannabis with higher THC potency (commonly assessed via THC:CBD ratio) may increase the risk for cannabis dependence and trigger/exacerbate anxiety. However, few studies of cannabis potency effects on cannabis dependence and anxiety have examined gender moderation.

Background: Despite the morbidity and mortality of venous thromboembolism, there is little evidence to guide postpartum thromboprophylaxis in patients at moderate risk. We aimed to assess the feasibility of conducting a double-blind, randomised trial of aspirin versus placebo in postpartum individuals with two or more venous thromboembolism risk factors, mild-to-moderate thrombophilia, or both.

Methods: The pilot PARTUM trial, a multi-national, randomised, double-blind, placebo-controlled trial, was conducted in seven centres across Canada, France, Ireland, and the Netherlands.
