Introduction: Tall cell subtype papillary thyroid cancer (TCS-PTC) is associated with aggressive disease features and worse patient outcomes. It remains unclear whether adjuvant radioactive iodine (RAI) ablation following thyroidectomy is associated with improved survival in TCS-PTC. The purpose of this review and meta-analysis was to determine whether adjuvant RAI was associated with improved survival in patients with TCS-PTC.

Prediction of Cumulative Exposure to Atherogenic Lipids During Early Adulthood.

J Am Coll Cardiol

September 2024

Department of Medicine (Cardiology), Northwestern University Feinberg School of Medicine, Chicago, Illinois, USA; Department of Preventive Medicine (Epidemiology), Northwestern University Feinberg School of Medicine, Chicago, Illinois, USA; Department of Pediatrics (Cardiology), Northwestern University Feinberg School of Medicine, Chicago, Illinois, USA.

Background: The ability of a 1-time measurement of non-high-density lipoprotein cholesterol (non-HDL-C) or low-density lipoprotein cholesterol (LDL-C) to predict the cumulative exposure to these lipids during early adulthood (age 18-40 years) and the associated atherosclerotic cardiovascular disease (ASCVD) risk after age 40 years is not clear.

Objectives: The objectives of this study were to evaluate whether a 1-time measurement of non-HDL-C or LDL-C in a young adult can predict cumulative exposure to these lipids during early adulthood, and to quantify the association between cumulative exposure to non-HDL-C or LDL-C during early adulthood and the risk of ASCVD after age 40 years.

Methods: We included CARDIA (Coronary Artery Risk Development in Young Adults Study) participants who were free of cardiovascular disease before age 40 years, were not taking lipid-lowering medications, and had ≥3 measurements of LDL-C and non-HDL-C before age 40 years.

Importance: Adaptive surgical trials are scarce, but adopting these methods may help elevate the quality of surgical research when large-scale RCTs are impractical.

Objective: Randomized-controlled trials (RCTs) are the gold standard for evidence-based healthcare. Despite an increase in the number of RCTs, the number of surgical trials remains unchanged.

Background: There is increasing evidence that people with hallucinations overweight perceptual beliefs relative to incoming sensory evidence. Past work demonstrating prior overweighting has used simple, nonlinguistic stimuli. However, auditory hallucinations in psychosis are often complex and linguistic.

Tachykinins and the potential causal factors for post-COVID-19 condition.

Lancet Microbe

Article Synopsis
  • Post-COVID-19 condition features common symptoms like pulmonary issues, fatigue, anxiety, and neurological dysfunction, indicating that both physical and mental health are affected.
  • Substance P, a neuropeptide, plays a significant role in the body's nervous and immune systems, impacting inflammation and communication between immune cells and the brain.
  • The study suggests that targeting tachykinin receptors could provide a new treatment strategy for alleviating post-COVID-19 symptoms.

Computational psychiatry is a field aimed at developing formal models of information processing in the human brain, and how alterations in this processing can lead to clinical phenomena. There has been significant progress in the development of tasks and how to model them, presenting an opportunity to incorporate computational psychiatry methodologies into large- scale research projects or into clinical practice. In this viewpoint, we explore some of the barriers to incorporation of computational psychiatry tasks and models into wider mainstream research directions.

Importance: Intensive vs standard treatment to lower systolic blood pressure (SBP) reduces risk of mild cognitive impairment (MCI) or dementia; however, the magnitude of cognitive benefit likely varies among patients.

Objective: To estimate the magnitude of cognitive benefit of intensive vs standard systolic BP (SBP) treatment.

Design, Setting, And Participants: In this ad hoc secondary analysis of the Systolic Blood Pressure Intervention Trial (SPRINT), 9361 randomized clinical trial participants 50 years or older with high cardiovascular risk but without a history of diabetes, stroke, or dementia were followed up.

Background: Recent advances in computational psychiatry have identified latent cognitive and perceptual states that predispose to psychotic symptoms. Behavioral data fit to Bayesian models have demonstrated an overreliance on priors (i.e.

Importance: Use of antihypertensive medications that stimulate type 2 and 4 angiotensin II receptors, compared with those that do not stimulate these receptors, has been associated with a lower risk of dementia. However, this association with cognitive outcomes in hypertension trials, with blood pressure levels in the range of current guidelines, has not been evaluated.

Objective: To examine the association between use of exclusively antihypertensive medication regimens that stimulate vs inhibit type 2 and 4 angiotensin II receptors on mild cognitive impairment (MCI) or dementia.

Lactose Intolerance, Dairy Avoidance, and Treatment Options.

Nutrients

December 2018

Department of Medicine, Division of Gastroenterology, Jewish General Hospital, McGill University School of Medicine, 3755 Cote St Catherine Rd, Room E110, Montreal, QC H3T 1E2, Canada.

Lactose intolerance refers to symptoms related to the consumption of lactose-containing dairy foods, which are the most common source for this disaccharide. While four causes are described, the most common is the genetically-determined adult onset lactose maldigestion due to loss of intestinal lactase governed by control of the gene by a 14,000 kb promoter region on chromosome 2. Gastrointestinal symptoms from lactose have expanded to include systemic effects and have also been confounded by other food intolerances or functional gastrointestinal disorders.

This report presents the Consolidated Standards of Reporting Trials (CONSORT) extension for the stepped wedge cluster randomised trial (SW-CRT). The SW-CRT involves randomisation of clusters to different sequences that dictate the order (or timing) at which each cluster will switch to the intervention condition. The statement was developed to allow for the unique characteristics of this increasingly used study design.

The Emerging Field of Geriatric Otolaryngology.

Otolaryngol Clin North Am

August 2018

Department of Otolaryngology-HNS, McGill University School of Medicine, 1001 Decarie Boulevard, Montreal, Québec H4A 3J1, Canada.

Sub-specialization within otolaryngology, like other specialties, is driven by accumulation of new knowledge and technology. For a variety of reasons, the establishment of a new subspecialty of geriatric otolaryngology is unlikely. Education of all otolaryngologists in the basic principles of gerontology and geriatric otolaryngology is achievable and represents a preferred strategy.

Irritable Bowel Syndrome (IBS) shares overlapping symptoms and some features of pathogenesis with Inflammatory Bowel Diseases (IBD: Crohn's disease [CD], and Ulcerative Colitis [UC]). Geographic markers such as latitude/sunshine and more recently lactase population distributions are found to be correlated with IBD. As a result of clinical and pathogenic similarities between the 2 conditions, some authorities questioned whether a connection exists between them.

Department of Emergency Medicine, Jewish General Hospital, McGill University School of Medicine, 3755 Cote Ste Catherine Road, Montreal, Quebec H3T 1E2, Canada. Electronic address:

Geographic patterns with diminishing rates from north to south toward the equator have been described for a number of diseases, putatively related largely to "western" lifestyle. Among these the inflammatory bowel diseases; Crohn's (CD) and Ulcerative colitis (UC) have been prominent in sharing distributions with a number of autoimmune diseases. One of the interesting associations is the epidemiologic similarity with multiple sclerosis (MS).

Introduction: Residency/fellowship training in hernia repair is still too widely characterized by the "see one, do one, teach one" model. The goal of this study was to perform a needs assessment focused on surgical training to guide the creation of a curriculum by SAGES intended to improve the care of hernia patients.

Methods: Using mixed methods (interviews and online survey), the SAGES hernia task force (HTF) conducted a study asking subjects about their perceived deficits in resident training to care for hernia patients, preferred training topics about hernias, ideal learning modalities, and education development.
