Functionally-informed fine-mapping identifies genetic variants linking increased CHD1L expression and HIV restriction in monocytes.

Human Immunodeficiency Virus Type 1 (HIV) set-point viral load is a strong predictor of disease progression and transmission risk. A recent genome-wide association study in individuals of African ancestries identified a region on chromosome 1 significantly associated with decreased HIV set-point viral load. Knockout of the closest gene, CHD1L, enhanced HIV replication in vitro in myeloid cells.

The Canadian Experience With Magnetic Esophageal Anastomosis: A Report From the Canadian Consortium for Research in Pediatric Surgery Study (CanCORPS).

Objective: Magnetic anastomosis is an innovative technique for establishing esophageal continuity in infants born with esophageal atresia. Few case series featuring this technology have been published, with even fewer reports on complications. We present the entire Canadian experience with this approach.

The New Niche: Transcatheter Aortic Valve Explantation and the Key Issues Concerning the Heart Team.

The volume of transcatheter aortic valve implantation (TAVI) for treatment of isolated aortic stenosis has far surpassed surgical aortic valve replacement (SAVR). There has been a consequent increase in TAVI explantation, now the fastest growing cardiac surgical procedure. Transcatheter heart valve explantation can be technically complex, with higher perioperative morbidity and mortality than routine SAVR or valve-in-valve TAVI.

A randomized trial comparing endovascular and surgical management of ruptured intracranial aneurysms excluded from previous trials.

Objective: Many patients with ruptured intracranial aneurysms (RIAs) underrepresented or excluded from previous randomized controlled trials (RCTs) comparing surgery with endovascular treatment (EVT) are still considered for surgical clipping, but the best management of these patients remains unknown.

Methods: The International Subarachnoid Aneurysm Trial-2 was a randomized trial comparing surgical versus EVT of RIAs considered for surgical clipping, despite the results of previous RCTs, and also eligible for EVT. The primary endpoint was death or dependency according to the modified Rankin Scale score (mRS score > 2) at 1 year.

Thought-Feeling Accuracy in Person Perception and Metaperception: An Integrative Perspective.

People often want to know what their interaction partners are thinking. How accurate are they, what information do they use, what predicts how accurate they will be, and does accuracy matter? We organize our review of thought-feeling accuracy, defined as the accuracy of individuals' judgments about the content of another person's thoughts and feelings in live interaction, around these questions. At the same time, we argue that often people are especially interested in what others are thinking about them, such that research on the accuracy of individuals' metaperceptions regarding others' views of them is highly relevant to understanding thought-feeling accuracy more broadly construed.

Canadian Stroke Best Practice Recommendations: Vascular cognitive impairment, 7th edition practice guidelines update, 2024.

The Canadian Stroke Best Practice Recommendations (CSPR) 7th edition includes this new module on the diagnosis and management of vascular cognitive impairment (VCI) with or without neurodegenerative disease. An expert writing group and people with VCI lived experience (PWLE) reviewed current evidence. Existing recommendations were reviewed and revised, and new recommendations added.

Dietary flaxseed: Cardiometabolic benefits and its role in promoting healthy aging.

Flaxseed, a rich source of omega-3 polyunsaturated fatty acid alpha-linolenic acid (ALA), lignans, and soluble fiber, has attracted attention for its potential to improve multiple cardiometabolic risk factors. While its benefits are well-recognized, comprehensive evaluations of its direct impact on clinical outcomes, such as the prevention or progression of cardiometabolic diseases, remain limited. Additionally, its potential to support healthy aging and longevity through fundamental biological mechanisms has not been fully elucidated.

Characterisation of intestinal amino acid and oleic acid absorption and their interaction in the Pacific spiny dogfish (Squalus suckleyi).

Elasmobranchs are commonly carnivores and are important in energy transfer across marine ecosystems. Despite this, relatively few studies have examined the physiological underpinnings of nutrient acquisition in these animals. Here, we investigated the mechanisms of uptake at the spiral valve intestine for two representative amino acids (-alanine, -leucine) and one representative fatty acid (oleic acid), each common to the diet of a carnivore, the Pacific spiny dogfish (Squalus suckleyi).

Neuropsychiatric symptoms and neuroimaging-based brain age in mild cognitive impairment and early dementia: A multicenter study.

Aim: Despite the clinical importance and significant social burden of neuropsychiatric symptoms (NPS) in dementia, the underlying neurobiological mechanism remains poorly understood. Recently, neuroimaging-derived brain-age estimation by machine-learning analysis has shown promise as an individual-level biomarker. We investigated the relationship between NPS and brain-age in amnestic mild cognitive impairment (MCI) and early dementia.

Basic Epigenetic Mechanisms.

The human genome consists of 23 chromosome pairs (22 autosomes and one pair of sex chromosomes), with 46 chromosomes in a normal cell. In the interphase nucleus, the 2 m long nuclear DNA is assembled with proteins forming chromatin. The typical mammalian cell nucleus has a diameter between 5 and 15 μm in which the DNA is packaged into an assortment of chromatin assemblies.

Doctors taking bribes from pharmaceutical companies is common and not substantially reduced by an educational intervention: a pragmatic randomised controlled trial in Pakistan.

Introduction: Incentive-linked prescribing, which is when healthcare providers accept incentives from pharmaceutical companies for prescribing promoted medicines, is a form of bribery that harms patients and health systems globally. We developed a novel method using data collectors posing as pharmaceutical company sales representatives to evaluate private doctors' engagement in incentive-linked prescribing and the impact of a multifaceted educational intervention on reducing this practice in Karachi, Pakistan.

Methods: We made a sampling frame of all doctors running for-profit, primary-care clinics and randomly allocated participants to control and intervention groups (1:1).

Phenotypic and Transcriptomic Changes in Acinetobacter baumannii in Rich and Minimal Growth Mediums.

Detailed analysis of air pollution in the Canadian prairie region: A step toward net-zero emission.

Industrial, agricultural, and natural pollution pose a critical problem for the Prairie provinces of Canada, with significant environmental and health concerns. This study addresses a critical knowledge gap by assessing the cumulative impacts of pollutants in the Prairie region, which hosts 40 % of the Canada's indigenous population, often living near these pollution sources. By innovatively integrating Sentinel-5P satellite data, Google Earth Engine, ArcGIS, and Python, we show the trends in CO, NO₂, HCHO, SO₂, and aerosols from 2019 to 2023 at high resolution for the entire region, which sheds new light on the dynamics that operate beyond conventional air quality monitoring.

Olaparib as treatment for platinum-sensitive relapsed ovarian cancer by BRCA mutation and homologous recombination deficiency: Phase 2 LIGHT study final overall survival analysis.

Background: LIGHT (oLaparib In HRD-Grouped Tumor types; NCT02983799) prospectively evaluated olaparib treatment in patients with platinum-sensitive relapsed ovarian cancer (PSROC) assigned to cohorts by known BRCA mutation (BRCAm) and homologous recombination deficiency (HRD) status: germline BRCAm (gBRCAm), somatic BRCAm (sBRCAm), HRD-positive non-BRCAm, and HRD-negative. At the primary analysis, olaparib treatment demonstrated activity across all cohorts, with greatest efficacy in terms of objective response rate and progression-free survival observed in the g/sBRCAm cohorts. The authors report final overall survival (OS).

The association between the COVID-19 pandemic and interpersonal relationships among youth with a child maltreatment history.

Introduction: The COVID-19 pandemic had significant impacts on youth health and well-being. Youth with prior inequities, such as those exposed to child maltreatment, may have experienced greater psychosocial challenges and long-term difficulties than their peers, including sustained interpersonal relationships problems. Given the importance of healthy relationships during adolescence and early adulthood, the significant impact the pandemic had on youth, and the potential disproportionate challenges for youth with a child maltreatment history, the purpose of the present study was to better understand changes in relational conflict among youth with and without a child maltreatment history from the perspectives of youth themselves.

The purpose of this study was to explore how family members of persons with intellectual and developmental disabilities perceived their loved ones' community transition process.

Method: Eight family members of persons with severe or profound intellectual and developmental disabilities formerly residing at the complex care facility of St.

Navigating ethics in HIV data and biomaterial management within Black, African, and Caribbean communities in Canada.

Background: This study explored the ethical issues associated with community-based HIV testing among African, Caribbean, and Black (ACB) populations in Canada, focusing on their perceptions of consent, privacy, and the management of HIV-related data and bio-samples.

Methods: A qualitative community-based participatory research (CBPR) approach was employed to actively engage ACB community members in shaping the research process. The design included in-depth qualitative interviews with 33 ACB community members in Manitoba, Canada.

Longitudinal increase in physical activity and adverse cardiovascular outcomes following the diagnosis of acute coronary syndrome.

Objectives: Physical activity (PA) provides protective effects against cardiovascular diseases, including ischaemic heart disease. However, recommending moderate to vigorous PA (MVPA) to patients with recent acute coronary syndrome (ACS) raises concerns owing to potential risk of recurrent ACS or fatal arrhythmias. This study investigated the association between longitudinal PA changes following an ACS diagnosis and subsequent cardiovascular outcomes, including non-fatal coronary events, non-fatal stroke and cardiovascular mortality.
