Prevalence and incidence of kidney diseases leading to hospital admission in people living with HIV in France: an observational nationwide study.
2019
ObjectivesTo describe hospitalisations for kidney disease (KD) among people living with HIV (PLHIV) in France and to identify the factors associated with such hospitalisations since data on the epidemiology of KD leading to hospitalisation are globally scarce.DesignObservational nationwide study using the French Programme de Médicalisation des Systèmes d’Information database.SettingFrance 2008–2013.ParticipantsAround 10 862 PLHIV out of a mean of 5 210 856 patients hospitalised each year. All hospital admissions with a main diagnosis code indicating KD (International Classification of Diseases, 10th revision codes, N00 to –N39) were collected.Main outcome measuresThe prevalence and incidenc…
Odontostomatological therapeutic possibilities in patients with sleep apnea
2009
Objectives: To evaluate the different therapeutic possibilities for treating Sleep Apnea/ Hypoapnea Syndrome (SAHS), as well as the effectiveness of such treatments, and to evaluate the epidemiological and clinical aspects of this syndrome. Study design: We carried out a meta-analytical, observational and retrospective study by selecting a total of 13 articles, which provided a sample size of 642 diagnosed cases of SAHS. Results: SAHS was more prevalent among males (88.7%) and the average age of diagnosis was 49.75 years old. In the majority of cases, these patients were found to be overweight, with an average body mass index of 28.32 Kg/ m². The average apnea / hypoapnea index was 31.64 ap…
Thiopurine adherence: high prevalence with low impact in UC outcomes
2021
Introduction Thiopurines are used as maintenance therapy in patients with ulcerative colitis (UC). There are contradictory results regarding the relationship between adherence to treatment and risk of relapse. Objectives To quantify and evaluate the trends in thiopurines prescription rates, and to determine the impact and risk factors of non-adherence. Methods Analytical, observational and retrospective study of UC patients, on thiopurines, included in the ENEIDA single-center registry from October 2017 to October 2019. We included adult patients under clinical remission at the beginning of the study on thiopurines maintenance treatment for at least 6 months before recruitment. Adherence wa…
Prevalence of metabolic syndrome and cardiovascular disease in a hypertriglyceridemic population
2011
BACKGROUND: We aim to study the prevalence of metabolic syndrome (MS), hypertension and diabetes, and their relationship to cardiovascular disease in subjects with hypertriglyceridemia. METHODS: This is an observational cross-sectional study, uncontrolled and multicentre study. Selected subjects were patients with hypertriglyceridemia (triglycerides, TG, ≥ 200 mg/dl) visited in the Lipid Units of the Spanish Arteriosclerosis Society who met the inclusion criteria. Prevalence of MS (ATPIII and IDF criteria, MS-ATPIII or MS-IDF), hypertension and diabetes were studied. The presence of cardiovascular disease (CVD) was also determined. RESULTS: The results showed that individuals referred for h…
The KARTAN study: a postmarketing assessment of Irbesartan in patients with hypertension.
2004
An important purpose of postmarketing surveillance of drugs is to better characterize the safety profile of drug therapy in the clinical setting. Another goal is to confirm the effectiveness of these drugs in patients who are candidates for antihypertensive therapy and who may have been excluded from Phase III studies. Irbesartan is a long-acting angiotensin II-receptor blocker specific for the angiotensin 1-receptor subtype that, in clinical trials in patients with hypertension, reduces blood pressure.The KARTAN (this word was derived from the first and last syllables of Karvea [trademark of Bristol-Myers Squibb Group, Madrid, Spain] and irbesartan) study was designed to confirm and extend…
Assessing preoperative anxiety using a questionnaire and clinical rating
2013
Background Preoperative anxiety and need for information can be detected during preoperative consultation via structured and standardised screening by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaire. Objective To identify the prevalence of preoperative anxiety and need for information, with regard to influencing factors such as age, sex, previous operation and grade of surgery, and to examine the level of agreement between patients' self-rating and physicians' ratings. Design Prospective observational study. Setting Department of Anaesthesiology, University Medical Centre of the Johannes Gutenberg University Mainz, Germany. Patients Two hundred seventeen patie…
Pretherapeutic MRI for decision-making regarding selective neoadjuvant radiochemotherapy for rectal carcinoma: interim analysis of a multicentric pro…
2012
Purpose: To study the accuracy of different cutoffs for an involved circumferential resection margin (CRM) compared with T and N categories measured by MRI as basis for selective application of neoadjuvant radiochemotherapy (nRCT) in rectal carcinoma. Materials and Methods: In a prospective multicenter observational study involving 153 primarily operated patients, the preoperative results of MRI with pathohistological findings of resected specimens were compared. Results: For a cutoff of ≤1 mm for involvement of the CRM, the accuracy of preoperative MRI was 90.9% (139/153). The negative predictive value was 98.5% (134/136). The four participating departments did not differ significantly. Fo…
Diagnostic Yield of 2 Strategies for Adult Celiac Disease Identification in Primary Care
2017
Goals: To compare the diagnostic yield and cost-consequences of 2 strategies, screening regardless of symptoms versus case finding (CF), using a point-of-care test (POCT), for the detection of celiac disease (CD) in primary care, to bridge the diagnostic gap of CD in adults. Materials and Methods: All subjects under 75 years of age who consecutively went to their general practitionersâ offices were offered POCT for anti-transglutaminase immunoglobulin A antibodies. The POCT was performed on all subjects who agreed, and then a systematic search for symptoms or conditions associated with higher risk for CD was performed, immediately after the test but before knowing the test results. The 2 …
HepaDisk – A new quality of life questionnaire for HCV patients
2019
Abstract Background Since most patients with hepatitis C virus (HCV) infection now receive treatment irrespective of liver disease severity, special attention to patient quality of life (QoL), including psycho-social aspects, is required. No QoL questionnaire is specific for patients with HCV. Aims To develop and validate a short Italian questionnaire (HepaDisk) assessing the QoL of patients affected by HCV with intuitive graphic results that is understandable by patients and physicians. Methods A questionnaire, drafted by a steering committee, underwent a Delphi survey. A multicenter, observational study was conducted to validate the developed HepaDisk versus other tools (CLDQ-I, SF-36, WP…
Incidence of non-melanoma skin cancer in patients treated with psoralen and ultraviolet A therapy.
2019
Abstract Introduction Studies reporting incidences of non-melanoma skin cancer (NMSC) are heterogeneous, depend on the geographic area of the studied population and are often short-term. The aim of this study is to determine the incidence of NMSC in patients treated with oral PUVA therapy in the Mediterranean area. Material and methods A retrospective, observational study was carried out with a sample of 234 patients treated with systemic PUVA between 1982 and 1996, carrying out a historical follow-up until May 2017. The incidence density rate of CCNM (crude and adjusted) was calculated by direct standardisation. The incidence of CCNM was compared with that reported in the general populatio…
