A Rare Case of Primary Gastric Melanoma
2019
Abstract Primary melanomas in the gastrointestinal tract are extremely rare, with an estimated prevalence of 0.5 to 1 case per million. Primary mucosal melanomas of gastric origin account for approximately 1–3% of all primary melanomas in the gastrointestinal tract. We present the case of a patient who underwent surgery due to primary gastric melanoma.
A Classification System for Decision-Making in the Management of Patients with Chronic Conditions
2021
Patients with chronic diseases are frequent users of healthcare services. The systematic use of stratification tools and predictive models for this group of patients can be useful for health professionals in decision-making processes. The aim of this study was to design two new classifier systems for detecting the risk of hospital admission for elderly patients with chronic conditions. In this retrospective cohort study, a set of variables related to hospital admission for patients with chronic conditions was obtained through focus groups, a health database analysis and statistical processing. To predict the probability of admission from the set of predictor variables, a logistic regression…
Alcohol use disorders in Europe: A comparison of general population and primary health care prevalence rates
2016
Aims Alcohol use disorders (AUDs) are prevalent in Europe but occurrence in primary care and the proportion of treated cases are understudied. This study reports prevalence of AUDs and their treatment in European primary health care settings and compares them with general population estimates. Procedure We sampled 358 general practitioners (GPs, refusal rate: 56.4%) across six European countries (Germany, Hungary, Italy, Latvia, Poland, and Spain), who assessed 13,003 patients including providing AUD diagnoses. A subsample of 8,476 patients (refusal rate: 17.8%) was interviewed subsequently, assessing DSM-IV AUD diagnoses via the Composite International Diagnostic Interview. Final AUD diagn…
Intervenciones preventivas en el ámbito de la atención primaria. El ejemplo del PAPPS. Informe SESPAS 2012
2012
ResumenObjetivosEl Programa de Actividades Preventivas y de Promoción de la Salud (PAPPS), que la Sociedad Española de Medicina de Familia y Comunitaria (semFYC) puso en marcha a finales de la década de 1980, tiene como objetivo la integración de las actividades preventivas y de promoción de la salud en el seno de las tareas desarrolladas en las consultas de atención primaria. Se pretende conocer el grado de cumplimentación del PAPPS en atención primaria.MétodosSe ha realizado una búsqueda bibliográfica de las publicaciones relacionadas con el PAPPS con el fin de evaluar su implementación y el impacto sus programas.ResultadosLas evaluaciones periódicas que se han ido realizando desde su ini…
Add-On Effect of Postural Instructions to Abdominopelvic Exercise on Urinary Symptoms and Quality of Life in Climacteric Women with Stress Urinary In…
2021
The aim of this study was to investigate the add-on effect of postural instructions to an abdominopelvic exercise program on incontinence urinary symptoms (UI symptoms) and quality of life (QoL) in climacteric women with stress urinary incontinence (SUI). A randomized controlled trial was performed with a total of 40 climacteric women with SUI aged between 46 and 75 years old. Participants were randomly assigned to two groups: a group performing an abdominopelvic exercise program (AEP) (n = 20) and a group performing abdominopelvic exercise with the addition of postural instructions (AEPPI) (n = 20). Primary outcome measures were UI symptoms, UI impact and QoL related to UI (UI-QoL), measur…
Immunochemical characterization of anti-acetylcholine receptor antibodies in primary biliary cirrhosis
1988
Although the presence of anti-mitochondrial antibodies is the main characteristic of primary biliary cirrhosis (PBC), other autoantibodies have been described in this disease. This study employs immunoblot methods to test whether the sera of PBC patients also contain antibodies directed against nicotinic acetylcholine receptors (AChR). We show that the majority of patients' sera indeed react with AChR just as sera of myasthenic patients do. In contrast, however, these anti-AChR antibodies do not lead to significant clinical symptoms of myasthenia. In all cases studied, PBC sera recognized a protein with the molecular weight of the alpha-chain of acetylcholine receptor (40 kDa). In addition,…
Effekt von Calcium und Magnesium auf die Parathormonfreisetzung aus humanem Parathyreoidea-Gewebe in vitro
1982
The effects of calcium and magnesium on parathyroid hormone release from eight adenomas causing primary hyperparathyroidism and six hyperplastic glands causing hypercalcemic secondary hyperparathyroidism were investigated in vitro using single cell suspensions from the respective tissue. We observed suppression of parathyroid hormone release with increasing concentrations of either cation. The quantitative hormone secretions of both adenomatous and hyperplastic glands was identical.
Arterial thrombosis in Philadelphia-negative myeloproliferative neoplasms predicts second cancer: a case-control study.
2020
Abstract Patients with Philadelphia-negative myeloproliferative neoplasm (MPN) are prone to the development of second cancers, but the factors associated with these events have been poorly explored. In an international nested case-control study, we recruited 647 patients with carcinoma, nonmelanoma skin cancer, hematological second cancer, and melanoma diagnosed concurrently or after MPN diagnosis. Up to 3 control patients without a history of cancer and matched with each case for center, sex, age at MPN diagnosis, date of diagnosis, and MPN disease duration were included (n = 1234). Cases were comparable to controls for MPN type, driver mutations and cardiovascular risk factors. The freque…
Improvement of knowledge and postural habits after an educational intervention program in school students
2019
To study the effect of an educational intervention programme concerning knowledge and postural habits for back health on a group of 10 to 11-year-old students. Two groups of 5th grade primary school students were selected. A control group (CG) (n=16), and an experimental group (EG) (n=16) who developed a back-health educational programme. A follow-up was carried out one month after the end of the intervention. The proposed educational intervention improved the results of both the knowledge and postural habits of the participants. The increase in the level of knowledge concerning health and back care in the daily lives of the EG (x̅=6.32) was significantly greater than that observed in the C…
Comparison between statistical and fuzzy approaches for improving diagnostic decision making in patients with chronic nasal symptoms
2014
This paper compares a fuzzy model, expressed in rule-form, with a well known statistical approach (i.e. logistic regression model) for diagnostic decision making in patients with chronic nasal symptoms. The analyses were carried out using a database obtained from a questionnaire administered to 1359 patients with nasal symptoms containing personal data, clinical data and skin prick test (SPT) results. Both the fuzzy model and the logistic regression model developed were validated using a data set obtained from another medical institution. The accuracy of the two models in identifying patients with positive or negative SPT was similar. This study is a preliminary step to the creation of a so…
