The relevance of depressive symptoms for the outcome of patients receiving vitamin K antagonists: results from the thrombEVAL cohort study.

2020

Abstract Aims Although depressive symptoms are highly prevalent in patients receiving oral anticoagulation (OAC), the relevance of depression for the outcome of anticoagulated individuals is unknown. Methods and results We analysed data from the multicentre cohort study thrombEVAL (NCT01809015) investigating the efficacy of OAC with vitamin K antagonists. There was an independent study monitoring, and an independent review panel assessed the endpoints. Out of n = 1558 participants, information about depressive symptoms, as measured by the two-item screener of the patient health questionnaire (PHQ-2), was available in n = 1405 individuals. The mean follow-up period was 28.04 months, with a s…

Obesity prevalence in Norwegian adults assessed by body mass index, waist circumference and fat mass percentage

2015

The prevalence of obesity presents serious public health challenges worldwide and is most commonly estimated by the categorization of body mass index (BMI). The purpose of this study was (i) to describe the sensitivity of BMI, waist circumference (WC) and fat mass percentage in the classification of overweight and obesity and (ii) to describe the prevalence of overweight and obesity using different measurement methods in a national sample of Norwegians. A total of 904 Norwegians (20-85 years) were randomly enrolled. Body weight, height, WC and skinfold thickness were measured; BMI and fat mass percentage (FP(skf) ) were calculated. The sensitivity and specificity varied from 77.0% to 86.9% …

High-Intensity Interval and Resistance Training Improve Health Outcomes in Older Adults With Coronary Disease.

2021

Both high-intensity interval training (HIIT) and resistance exercises (R) are used in cardiac rehabilitation in patients with coronary artery disease (CAD). However, the combined effect of an HIIT + R exercise program in older adults with CAD is not well investigated. The study's purpose was to assess the changes in anthropometric parameters, physical activity, functional capacity, physiological parameters, and quality of life (QoL) in this population following a combined HIIT + R program.The study was a 2-group (n = 45 each) randomized controlled single-blinded trial.The study was done at a treatment clinic of a tertiary hospital. The mean age of participants was 69.23 ± 4.9 years. The HII…

Central Obesity and Survival in Subjects With Coronary Artery Disease

2011

Objectives The aim of this study was to examine the association of central (waist circumference [WC] and waist-hip ratio [WHR]) and total obesity (body mass index [BMI]) measures with mortality in coronary artery disease (CAD) patients. Background The question of which measure of obesity better predicts survival in patients with CAD is controversial. Methods We searched OVID/Medline, EMBASE, CENTRAL, and Web of Science from 1980 to 2008 and asked experts in the field for unpublished data meeting inclusion criteria, in which all subjects had: 1) CAD at baseline; 2) measures of WC or WHR; 3) mortality data; and 4) a minimum follow-up of 6 months. Results From 2,188 studies found, 6 met inclus…

Weight loss in Alzheimer’s disease, vascular dementia and dementia with Lewy bodies: Impact on mortality and hospitalization by dementia subtype

2021

Objectives Loss of weight is associated with cognitive decline as well as several adverse outcomes in dementia. The aim of this study was to assess whether weight loss is associated with mortality and hospitalization in dementia subtypes. Methods A cohort of 11,607 patients with dementia in Alzheimer's disease (AD), vascular dementia (VD), or dementia with Lewy bodies (DLB) was assembled from a large dementia care health records database in Southeast London. A natural language processing algorithm was developed to established whether loss of weight was recorded around the time of dementia diagnosis. Cox proportional hazard models were applied to examine the associations of reported weight l…

Identifying the Profile of Helicobacter pylori–Negative Gastric Cancers: A Case-Only Analysis within the Stomach Cancer Pooling (StoP) Project

2022

Abstract Background: The prevalence of Helicobacter pylori–negative gastric cancer (HpNGC) can be as low as 1%, when infection is assessed using more sensitive tests or considering the presence of gastric atrophy. HpNGC may share a high-risk profile contributing to the occurrence of cancer in the absence of infection. We estimated the proportion of HpNGC, using different criteria to define infection status, and compared HpNGC and positive cases regarding gastric cancer risk factors. Methods: Cases from 12 studies from the Stomach cancer Pooling (StoP) Project providing data on H. pylori infection status determined by serologic test were included. HpNGC was reclassified as positive (eight st…

Heart rate dynamics and lactate following high-intensity race-pace continuous vs interval workouts in highly trained athletes.

2020

AbstractPurposeThe present study aimed to compare the physiological responses of high-intensity race-pace continuous vs. interval workouts commonly used in middle-distance athletics, by means of analyzing post-exercise cardiac autonomic regulation and lactate.MethodsNineteen highly-trained 800-m male runners were asked to run a 600-m race-pace continuous workout and a 2 × 4 × 200-m interval training, counterbalanced and randomized within one week of difference. Blood lactate jointly with linear and nonlinear heart rate dynamics were assessed during the immediate 15-min recovery. Age-category (Under23-Senior vs. Juvenile-Junior) was considered as an inter-subject factor.ResultsPeak lactate w…

Quality of Anticoagulation With Vitamin K Antagonists

2015

Background Vitamin K antagonists (VKA) have a narrow therapeutic range, and literature analysis reveals poor quality of anticoagulation control. We sought to assess the prevalence of poor anticoagulant control in patients under VKA treatment in the prevention of stroke for atrial fibrillation (AF). Hypothesis Control of anticoagulation with VKA is inadequate in a high percentage of patients with AF. Methods Patients with AF under VKA treatment were prospectively recruited in this observational registry. The sample comprised 948 patients. The estimated time spent in the therapeutic range (TTR) was calculated, and variables related with a TTR >65% were analyzed. Results Mean age was 73.8 ± 9.…

Combining Body Mass Index With Measures of Central Obesity in the Assessment of Mortality in Subjects With Coronary Disease

2013

Objectives This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based on a combination of body mass index (BMI) and measures of central obesity. Background In CAD patients, mortality has been reported to vary inversely with BMI (“obesity paradox”). In contrast, central obesity is directly associated with mortality. Because of this bi-directional relationship, we hypothesized that CAD patients with normal BMI but with central obesity would have worse survival compared with subjects with other combinations of BMI and central adiposity. Methods We included 15,547 participants with CAD who took part in 5 studies from 3 continents. Multivariate stratified…

Background It remains unclear whether the distal location of deep vein thrombosis (DVT) is independently associated with a lower risk of recurrence in all patients, or represents a marker of the presence and severity of provoking factors for venous thromboembolism (VTE). Methods We investigated the impact of distal (vs. proximal) DVT location on the risk of developing symptomatic, objectively confirmed recurrent VTE in 831 patients with a first acute symptomatic DVT not associated with pulmonary embolism (PE), who were stratified by the presence of transient or persistent risk factors at baseline. The primary outcome was symptomatic, objectively diagnosed recurrent VTE, including proximal …
