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We searched OVID/Medline, EMBASE, CENTRAL, and Web of Science from 1980 to 2008 and asked experts in the field for unpublished data meeting inclusion criteria, in which all subjects had: 1) CAD at baseline; 2) measures of WC or WHR; 3) mortality data; and 4) a minimum follow-up of 6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…

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…

2019

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 …

Hospital Readmission after Major Pulmonary Resection for Lung Cancer in France: A Nationwide Medico-Administrative Database

2019

Objectives: After major pulmonary resection for lung cancer, hospital readmission is considered an indicator of the quality of care. Our main objective was to define the readmission rate at 30 days after pulmonary resection. Secondary objectives were to determine the causes and predictive factors. Methods: Data for all patients operated for lung cancer were extracted from the national medico-administrative database of the Programme de Medicalisation des Systemes d'Information (PMSI). Thirty-days hospital readmission was defined as any new hospitalization within 30 days after discharge from the surgical department following major lung resection, regardless of the reason for readmission. Resu…

Objective Assessment of Pulmonary Embolism Can Be Deferred without Increased Risk

2005

Abstract Background. Management of patients with suspected Pulmonary Embolism (PE) is problematic if diagnostic imaging is not available. Pretest Clinical Probability (PCP) and D-dimer (D-d) assessment were shown to be useful to identify those high risk patients for whom empirical, protective anticoagulation is indicated (Siragusa S et al. Arch Intern Med2004;164:2477–82). Objective of the study. In consecutive patients with suspected PE, we evaluated whether PCP and D-d assessment, together with the use of low molecular weight heparins (LMWHs), allow objective appraisal of PE to be deferred for up to 72 hours. Methods. In case of deferment of diagnostic imaging for PE, patients identified …

Prognostic factors for remission of and survival in acquired hemophilia A (AHA): results from the GTH-AH 01/2010 study

2015

Acquired hemophilia A (AHA) is caused by autoantibodies against factor VIII (FVIII). Immunosuppressive treatment (IST) results in remission of disease in 60% to 80% of patients over a period of days to months. IST is associated with frequent adverse events, including infections as a leading cause of death. Predictors of time to remission could help guide IST intensity but have not been established. We analyzed prognostic factors in 102 prospectively enrolled patients treated with a uniform IST protocol. Partial remission (PR; defined as no active bleeding, FVIII restored >50 IU/dL, hemostatic treatment stopped >24 hours) was achieved by 83% of patients after a median of 31 days (range 7-362…

Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting for Ostial/Midshaft Lesions in Unprotecte…

2014

Objectives The aim of this study was to report the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for ostial/midshaft lesions in an unprotected left main coronary artery (ULMCA). Background Data regarding outcomes in these patients are limited. Methods Of a total of 2,775 patients enrolled in the DELTA multinational registry, 856 patients with isolated ostial/midshaft lesions in an ULMCA treated by PCI with DES (n = 482) or CABG (n = 374) were analyzed. Results At a median follow-up period of 1,293 days, there were no significant differences in the propensity score-adjusted analyses for …
