Acute myocardial infarction occurring in versus out of the hospital: patient characteristics and clinical outcome

2000

OBJECTIVES We describe the baseline characteristics and clinical course of patients who had an acute myocardial infarction (AMI) during their hospital stay. BACKGROUND In comparison with patients who had an AMI outside of the hospital (prehospital AMI), the data on patients who had an AMI in the hospital are poorly described. METHODS Patients with an in-hospital AMI were prospectively registered in the Southwest German Maximal Individual TheRapy in Acute myocardial infarction (MITRA) study and compared with patients with prehospital AMI. RESULTS Of 5,888 patients with AMI, 403 patients (6.8%) had an in-hospital AMI. These patients were older, more often male and sicker as compared with the …

Endophthalmitis in cataract surgery

1999

Abstract Objective To document perioperative prophylactic treatment and to evaluate the risk factors for endophthalmitis after cataract surgery. Design Cross-sectional study via anonymous survey. Participants Four hundred sixty-nine centers in Germany were queried. Results A total of 311 (67%) questionnaires were received, with each center reporting an average of 900 cataract surgeries per year (total, 340,633 surgeries in 1996). Respondents reported a total of 267 cases of endophthalmitis, which resulted in a mean responder-specific endophthalmitis rate of 0.148% versus a median rate of 0%. Statistical analysis via Poisson regression suggested that sclerocorneal incisions were associated w…

2019

This study investigated the use of performance-enhancing substances in recreational triathletes who were competing in German races at distances ranging from super-sprint to long-distance, as per the International Triathlon Union. The use of legal drugs and over-the-counter supplements over the previous year, painkillers over the previous 3 months, and the potential three-month prevalence of physical doping and or cognitive doping in this group were assessed via an anonymous questionnaire. The Randomised Response Technique (RRT) was implemented for sensitive questions regarding “prescription drugs […] for the purpose of performance enhancement […] only available at a pharmacy or on the black…

Factors associated with dental fluorosis in three zones of Ecuador

2019

Background To determine the prevalence of dental fluorosis in 10-12 year-old school children, in three provinces of the inter-andean Region of Ecuador: Imbabura, Pichincha and Chimborazo, as well as the relationship between certain factors, considering that the latest studies go back to the year 2009. Material and methods A cross-sectional and observational study was proposed. A sample of 599 was calculated at 95% of confidence considering population projections for children between 10 and 12 old of three zones of Ecuador. However, 608 school children, who had the acceptance and informed consent of their parents to participate, completed a survey about factors associated with dental fluoros…

Meta-analysis of the efficacy of different training strategies in animal models of ischemic stroke.

2013

Background and Purpose— Although several studies have shown beneficial effects of training in animal stroke models, the most effective training strategy and the optimal time to initiate training have not been identified. The present meta-analysis was performed to compare the efficacy of different training strategies and to determine the optimal time window for training in animal stroke models. Methods— We searched the literature for studies analyzing the efficacy of training in animal models of ischemic stroke. Training was categorized into forced physical training, voluntary physical training, constraint-induced movement therapy, and skilled reaching training. Two reviewers independently …

Prevalencia de fibrilación auricular en la población española de 60 o más años de edad. Estudio PREV-ICTUS

2007

Introduction and objectives. The aims of this study were to determine the prevalence of atrial fibrillation in individuals aged 60 years or more in Spain using a random sample of the population and to identify associated factors. Methods. An analysis of the PREV-ICTUS study, a randomized cross-sectional population-based study of individuals aged 60 years or more, was carried out. Data on demographic variables, cardiovascular risk factors, and cardiovascular disease were obtained from medical records. The diagnosis of atrial fibrillation was based on the patient’s medical history and an electrocardiogram performed during the study. Results. In the 7108 individuals studied (mean age, 71.9 [7.…

Tumor diagnosis preceding Parkinson's disease: A case-control study

2004

Lower cancer risk in Parkinson's disease (PD) patients compared to the general population has been reported. However, most of the studies were based on death certificates. We designed a case–control study to estimate the association of tumor preceding PD onset and PD. PD patients were matched by age and gender to PD-free individuals, randomly selected from the municipalities of residence of cases. Occurrence of tumors preceding PD onset was assessed through a structured questionnaire. Neoplasms were categorized as benign, malignant, or of uncertain classification, and endocrine-related or not. Odds ratios (OR) were calculated using conditional logistic regression and adjusted for tumor cate…

Accuracy of the water-siphon test associated to barium study in a high prevalence gastro-oesophageal reflux disease population: a novel statistical a…

2010

Summary Rationale, aims and objectives  Gastro-oesophageal reflux disease (GORD) is ‘a condition which develops when the reflux of gastric content causes troublesome symptoms or complications’. Instrumental diagnostic tests generally used for GORD are 24-hour pH-metry and upper gastrointestinal (GI) endoscopy but barium study associated with provocative manoeuvres such as the water-siphon test (WST), has also been used for GORD. The aim of this paper was to estimate the accuracy of several tests in patients with GORD in a tertiary care setting, focusing on WST, which is rapid and non-invasive, simple to perform and well-tolerated by patients. Method  A total of 172 consecutive patients, sym…

The value of total thyroidectomy as the definitive treatment for Graves’ disease: A single centre experience of 594 cases

Frailty and risk of complications in head and neck oncologic surgery. Systematic review and dose-response meta-analysis

2021

Background There is emerging evidence that frail individuals present a decreased physiological reserve, decreased ability to maintain homeostasis, and increased vulnerability to stressors. The concept of frailty has become increasingly recognized as a valuable measure in oncological surgical patients, including those with head and neck cancer. Preoperative screening for frailty may provide an individualized risk assessment that can be used by an interdisciplinary team for preoperative counseling and to improve outcomes. The aim of this meta-analysis was to evaluate the relationship between frailty and the risk of major postoperative complications in frail individuals submitted to head and n…
