Obesity

Knee osteoarthritis (OA) typically presents with joint pain that is exacerbated by use and alleviated with rest. There is relatively brief, self-limited morning stiffness and absence of constitutional symptoms. Overweight and obesity are the most important modifiable risk factors. Although pharmacologic and nonpharmacologic interventions are generally effective at alleviating pain and improving physical function, they do not fundamentally reverse the pathologic and radiographic process of knee OA. As the severity of disease increases, the magnitude of pain and functional impairment intensifies...

OBJECTIVE: Test the efficacy of a brief 2-hr parenting intervention in increasing protective factors against and reducing risk factors for infant obesity. METHOD: A 2 (Baby Healthy Living Triple P vs. care-as-usual) × 3 (baseline, postintervention, 6-month follow-up) design was used. Eighty-two parents of 4- to 18-month-old infants meeting at least two risk factors for early childhood obesity (e.g., parent/child overweight, low education level) were randomized to intervention (n = 42) or control group (n = 40)...

BACKGROUND: Frailty is associated with obesity-related comorbidities, but the relationship with nonalcoholic fatty liver disease (NAFLD) in people with HIV has been incompletely described. Our objective was to assess the associations between NAFLD and frailty. METHODS: Cross-sectional and longitudinal analysis of men in the Multicenter AIDS Cohort Study. NAFLD was defined as a liver/spleen ratio <1.0 on abdominal computed tomography scans; frailty was defined by the frailty phenotype as having 3 of the following: weakness, slowness, weight loss, exhaustion, and low physical activity...

OBJECTIVES: To describe and report outcomes of a minimally invasive open intramedullary (IM) fibular nailing technique for fixation of ankle fractures. METHODS: Design: Case Series. SETTING: Urban Level 1 trauma center. PATIENT SELECTION CRITERIA: Adult patients with ankle fractures (OTA 44A-C) treated with locked fibular IM nailing via a minimally invasive open technique for fracture and syndesmotic reduction between 2021 and 2024...

BACKGROUND: Cardiometabolic diseases cover a spectrum of interrelated conditions linked to metabolic dysfunctions and/or cardiovascular disorders, including systemic arterial hypertension, diabetes mellitus, dyslipidemia, and obesity. Cocoa is a rich source of dietary polyphenols and has been associated with cardiovascular health benefits. However, beneficial effects of cocoa consumption and appropriate quantities in decreasing cardiometabolic risk factors have yet to be established. Therefore, we will conduct a systematic review and meta-analysis to examine the effects of cocoa consumption on cardiometabolic risk markers (total cholesterol, HDL, LDL, triglycerides, blood glucose, glycated hemoglobin, waist circumference, abdominal circumference, body mass index, systolic blood pressure and diastolic blood pressure) in adults with or without established cardiovascular risk factors...

The gut microbiome is essential for maintaining organismal health. Gut microbiota may be disrupted through external factors like dietary change, which can lead to gut inflammation resulting in obesity. Hibernating mammals develop low-grade gut inflammation when they accumulate fat deposits in preparation for hibernation, making them useful models for studying the relationship between the microbiome, inflammation, and weight gain. Nonsteroidal anti-inflammatory drugs and steroids are commonly used in humans to target gut inflammation, but how these drugs affect the gut microbiome and its stability is unclear...

Metabolic dysfunction-associated diseases often refer to various diseases caused by metabolic problems such as glucose and lipid metabolism disorders. With the improvement of living standards, the increasing prevalence of metabolic diseases has become a severe public health problem, including metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), diabetes and obesity. These diseases are both independent and interdependent, with complex and diverse molecular mechanisms...

Youth-onset type 2 diabetes is a heterogeneous disease with increasing prevalence in relation to increased rates of obesity in children. It has genetic, epigenetic, social, and environmental determinants. Youth-onset type 2 diabetes is alarming given a rapidly progressive course compared with the course of adult-onset disease, early-onset vascular complications, and long-term exposure to hyperglycemia and associated complications. It is often preceded by "prediabetes," a disease phase where defects in β-cell function relative to insulin sensitivity emerge...

BACKGROUND: Atherosclerotic cardiovascular diseases remain the primary cause of mortality in Italy. Individuals with a history of acute coronary syndrome, peripheral arterial disease, and ischemic stroke/transient ischemic attack face an elevated risk of recurrent major adverse cardiovascular events, including mortality. The population aging, coupled with increasing risk factors such as diabetes mellitus and obesity, exacerbates the disease's economic impact. OBJECTIVES: This study aims to comprehensively assess the economic burden of atherosclerotic cardiovascular diseases in Italy, specifically focusing on direct healthcare costs...

BACKGROUND: Severe obesity greatly influences the difficulty of colorectal cancer surgery and has been reported to prolong operative time, increase the rate of laparotomy, and elevate increase postoperative complications. We investigated the efficacy of laparoscopic sleeve gastrectomy (LSG) for preoperative weight loss to ensure safe colorectal cancer surgery. CASE PRESENTATION: A 51 year-old female with a body mass index of 43.5 kg/m2 was referred to our hospital due to a positive fecal occult blood test...

BACKGROUND: In 2023, the first evidence-based classification for recurrent weight gain (RWG) after metabolic and bariatric surgery was introduced. It uses early and late follow-up weight loss benchmarks based on standard deviations (SD) of percentage total weight loss(%TWL) results from the large Dutch Audit for Treatment of Obesity (DATO) registry (n > 18,000). We aimed to validate this classification and confirm its clinical relevance with an external cohort. METHODS: The DATO-based classification defines all RWG as grade 1, as long as weight-loss does not drop below DATO's late-follow-up minus one SD benchmark (20%TWL)...

Postprandial dyslipidemia is commonly present in people with type II diabetes and obesity and is characterized by overproduction of apolipoproteinB48 (apoB48)-containing chylomicron particles from the intestine. Peripheral serotonin is emerging as a regulator of energy homeostasis with profound implications for obesity, however, its role in dietary fat absorption and chylomicron production is unknown. Chylomicron production was assessed in Syrian golden hamsters by administering an olive oil gavage and i.p...

OBJECTIVES: This study investigated obstructive sleep apnea (OSA)-related risk factors in children and adolescents. MATERIALS AND METHODS: Records of 187 subjects from a private medical clinic were reviewed. Overnight polysomnography recordings and self/parent reports were gathered. Descriptive analysis of sociodemographic, anthropometric, sleep quality and sleep architecture variables and OSA diagnosis were performed. Associations between independent variables and OSA diagnosis were assessed through multivariable logistic regression with robust variance, with a significance level of 5%...

BACKGROUND: Recent studies have demonstrated an obesity paradox, where obese patients with cardiovascular disease have a better outcome compared to those with normal weight. However, the effect of obesity and body mass index (BMI) on the outcome of patients with cardiac resynchronization therapy (CRT) devices remains unclear. The current study aims to investigate this relationship using all available published data. METHODS: We systematically reviewed studies from Medline and EMBASE databases from inception to January 2024...

Intermittent fasting (IF) plays a critical role in mitigating obesity, yet the precise biological mechanisms require further elucidation. Here Orosomucoid 2 (Orm2) is identified as an IF-induced hepatokine that stimulates adipose browning. IF induced Orm2 expression and secretion from the liver through peroxisome proliferator-activated receptor alpha (PPARα). In adipose tissue, Orm2 bound to glycoprotein 130/interleukin 23 receptor (GP130/IL23R) and promoted adipose browning through the activation of p38 mitogen-activated protein kinases (p38-MAPK)...

BACKGROUND: The metabolic syndrome phenotype of individuals with obesity is characterized by elevated levels of triglyceride-rich lipoproteins and remnant particles, which have been shown to be significantly atherogenic. Understanding the association between adipokines, endogenous hormones produced by adipose tissue, and remnant cholesterol (RC) would give insight into the link between obesity and atherosclerotic cardiovascular disease. METHODS AND RESULTS: We studied 1791 MESA (Multi-Ethnic Study of Atherosclerosis) participants who took part in an ancillary study on body composition with adipokine levels measured (leptin, adiponectin, and resistin) at either visit 2 or visit 3...

BACKGROUND: Previous studies have found that exposure to childhood environmental stress is associated with cardiometabolic risk. However, it is not known whether individual health behaviors disrupt this relationship. This study prospectively evaluated the relationship between cumulative environmental stress in a low-income sample and cardiometabolic risk in middle childhood and examined whether child health behaviors attenuated this relationship. METHODS AND RESULTS: In a cohort of children (n=338; 57% Hispanic children; 25% Black children), environmental stressors (family and neighborhood factors representing disadvantage/deprivation) and child health behaviors (accelerometry measured physical activity; parent-reported screen time and diet recalls) were measured over 5 time points beginning when children were aged 2 to 4 years and ending when they were aged 7 to 11 years...

AIM: To examine the likelihood of mortality or rehospitalization following acute coronary syndrome with glyburide versus gliclazide use in adults with type 2 diabetes undergoing cardiac catheterization. RESEARCH DESIGN AND METHODS: This retrospective cohort study used clinical data linked with administrative health data from Alberta, Canada between April 2008 and March 2021. Three methods were used to define exposure to glyburide and gliclazide in the year before catheterization...

AIMS: Tirzepatide is a first-in-class combination glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide 1 receptor agonist (GLP1-RA) approved for treatment of adults with type 2 diabetes mellitus (T2DM) and chronic weight management. The aim of this analysis was to assess the real-world efficacy of tirzepatide in patients with T2DM. METHODS: This retrospective observational study evaluated patients with T2DM from a large urban academic medical centre who received at least 3 months of continuous tirzepatide treatment...
