Sociodemographic, Lifestyle and Medical Factors Associated with Helicobacter Pylori Infection
2020
Background and Aims: The prevalence of Helicobacter pylori (H. pylori) infection is higher in developing countries and is often linked to lower socioeconomic status. Few studies have investigated the association between H. pylori and individual level characteristics in Europe, where several countries have a high prevalence of H. pylori infection. The study aimed to identify risk factors for H. pylori infection among adults in a large clinical trial in Latvia.
 Methods: 1,855 participants (40-64 years) of the “Multicenter randomized study of H. pylori eradication and pepsinogen testing for prevention of gastric cancer mortality” (GISTAR study) in Latvia tested for H. pylori IgG antibodi…
Depression and functional impairment independently contribute to decreased quality of life in cancer patients prior to chemotherapy
2007
An inverse association either between depression or impaired functional status and quality of life (QoL) has been reported for cancer patients, but the independent effect of depression or depressive symptoms and of functional impairment on QoL is unclear.We investigated the prevalence of depression or depressive symptoms with the Beck Depression Inventory (BDI), the functional impairment with the ECOG-Performance-Status (ECOG-PS) and the QoL with the EORTC-QLQ-C30 questionnaire in a sample of 175 hospitalised cancer patients prior to the start of chemotherapy.Sixteen of 175 patients (9.1%) screened positive for major depression, 29 (16.6%) had mild to moderate depressive symptoms. In 11 of …
Predicting relapse after a first episode of non-affective psychosis: A three-year follow-up study
2011
Preventing relapse during the first years of illness has a critical impact on lifelong outcomes in schizophrenia. A better understanding and improvement in factors which influence relapse should diminish the risk of relapse and consequently improve the outcome of the illness.To identify factors associated with relapse after 3 years of a first episode in a sample of non-affective psychosis patients who are representative of clinical practice in an epidemiological catchment.We analyzed socio-demographic and clinical data from a cohort of patients who were treated in a specialized early intervention service and who were at risk of relapse during a 3-year follow-up. Univariate analyses, logisti…
Framingham score, renal dysfunction, and cardiovascular risk in liver transplant patients
2015
Cardiovascular (CV) events represent major impediments to the long-term survival of liver transplantation (LT) patients. The aim of this study was to assess whether the Framingham risk score (FRS) at transplantation can predict the development of post-LT cardiovascular events (CVEs). Patients transplanted between 2006 and 2008 were included. Baseline features, CV risk factors, and CVEs occurring after LT (ischemic heart disease, stroke, heart failure, de novo arrhythmias, and peripheral arterial disease) were recorded. In total, 250 patients (69.6% men) with a median age of 56 years (range, 18-68 years) were included. At transplantation, 34.4%, 34.4%, and 33.2% of patients, respectively, ha…
Clinical observations and risk factors for tinnitus in a Sicilian cohort.
2014
The aims of this study were to determine the distribution of risk factors associated with tinnitus analysing their role in the development of tinnitus and the effects of their interaction; to evidence the importance of a suitable and adequate clinical and audiologic assessment to avoid those modifiable risk factors responsible for cochlear dysfunction and tinnitus onset. 46 subjects with tinnitus and 74 controls were studied according to: age, sex, Body Mass Index (BMI), neck circumference, tobacco smoking, feeling fatigue or headache, self reporting snoring, hypertension, diabetes, coronary heart disease, and/or hyperlipidemia, and laboratory finding as lipid profile and levels of reactive…
Smoking, diabetes, blood hypertension: possible etiologic role for Peyronie’s disease? Analysis in 279 patients with a control group in Sicily
2015
Objective: To assess the proportion of patients with Peyronie’s Disease (PD) and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. Materials and methods: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD), the second one composed by patients with other andrological diseases (control arm). For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated q…
Evaluation of socket healing in patients undergoing bisphosphonate therapy: experience of a single Institution
2012
Objective: To assess the clinical features of exodontias performed in cancer patients who have been receiving intravenous bisphosphonates (BPs). Study Design: This is a retrospective cohort study using a sample of 20 patients receiving BPs who had 62 teeth extracted. An univariate analysis was applied to calculate socket healing time (HT), comparing among exodontias performed according to cause, such as periodontal disease or caries, type of BP, and use of corticosteroid. In order to analyze the influence of each variable on HT, multiple statistical analyses were performed through logistic multiple regression. Results: From the 62 tooth extractions performed, 5 exodontias had evolved to 4 s…
Nonocclusion and Early Reopening of the Great Saphenous Vein After Endovenous Laser Treatment Is Fluence Dependent
2004
Background. Parameters influencing failure and recanalization rates of endovenous laser treatment (ELT) of the great saphenous vein (GSV) are still to be determined. Objective. To evaluate treatment-related parameters of ELT with respect to early failure of occlusion or recanalization of GSVs. Methods. A series of 77 consecutive patients received ELT of 106 GSVs with continuous pullback of the laser fiber. Duplex examination was performed at 1 day, 4 weeks, and 3 months after the procedure. Clinical patient and vessel characteristics as well as technical parameters of the ELT procedure were evaluated via multiple logistic regression analysis. Results. A median vein length of 60 cm (range of…
Peri-Tumoral Inflammatory Cell Infiltration in OSCC: A Reliable Marker of Local Recurrence and Prognosis? An Investigation Using Artificial Neural Ne…
2011
The presence of inflammatory reaction in peri-tumoural connective tissue is generally considered as a defense mechanism against cancer, but inflammation tissue in malignant transformation and early steps of oncogenesis has been recently proven to play a supporting and aggravating role in some carcinomas. Aims of this retrospective study were to evaluate in OSCCs the independent association of peri-tumoral inflammatory infiltrate (PTI) with local recurrence (LR) or survival outcome, and to verify whether PTI can be considered a marker of prognosis. Data from 211 cases of OSCC, only surgically treated between 1990 and 2000, were collected and retrospectively analyzed for PTI and the event LR…
Effect of obesity on disease-free and overall survival in node-positive breast cancer patients in a large French population: A pooled analysis of two…
2014
Abstract Background To examine the association between baseline body mass index (BMI), and disease-free survival (DFS) and overall survival (OS) in a large French early-stage breast cancer population included in the UNICANCER Programme d’Action Concerte Sein-01 (PACS01) and PACS04 phase III randomised trials. Methods After a median follow-up of 5.9 years, this report analyses 4996 patients with node-positive breast cancer, and randomly assigned to adjuvant anthracycline-based chemotherapy combined or not with taxanes. Univariate analyses were used to study the effects of well known prognostic factors and BMI on DFS and OS. BMI was obtained at baseline, before chemotherapy initiation, and ob…
