Characteristics of hepatocellular carcinoma in Italy.

1998

This study aimed to assess the main features of hepatocellular carcinoma at the time of diagnosis in Italy, particularly in relation to the presence or absence of underlying cirrhosis, hepatitis virus marker patterns, age of the subjects and alpha-foetoprotein values.A total of 1148 patients with hepatocellular carcinoma seen at 14 Italian hospitals in the 1-year period from May 1996 to May 1997 were the subjects of this prevalence study. Both newly diagnosed cases (incident cases) and cases diagnosed before May 1996 but still attending the hospitals during the study period (prevalent cases) were included.We found that 71.1% of cases were positive for hepatitis C virus antibodies but negati…

The influence of regular physical activity on lung function in paraplegic people

2015

Cross-sectional study. The main goal of this study was to examine the influence of regular physical activity (PA) on lung volumes and flows. The study was conducted in the Vall d’Hebron Hospital, Barcelona (Spain), and La Fe Hospital, Valencia (Spain). Spirometric tests were performed to 67 paraplegics, and differences were established between the active group (AG) (n=37) that performed >60 min per week of moderate-to-vigorous PA (MVPA) and 30 non-AG (NAG). Further, we established the relationship between the spirometric and PA variables and between being active and reaching the lower limit of normal (LLN) of the spirometric variables. AG had greater values than the NAG: FVC (P 0.05). The p…

The difference in risk of chronic pulmonary disease morbidity and mortality between former elite athletes and ordinary men in Finland.

2019

The impact of a history of competitive sports on later smoking behaviour and occurrence of chronic pulmonary diseases is poorly known. We investigated how a history of elite level sports predicted later pulmonary disease morbidity and mortality. Chronic pulmonary disease incidence was assessed from national hospital and cause-of-death registers from 1970 to 2015 among Finnish male former elite athletes (n = 2078) and matched controls (n = 1453) alive in 1970 (mean age 45.0 years). Hazard ratios (HRs) were calculated by Cox proportional hazards model. In 1985, cohort members reported on their smoking habits, engagement in physical activity/sports and physician-diagnosed chronic diseases. The…

Characterization of measles virus strains circulating in Southern Italy (Palermo area, Sicily) between 2010 and 2011

2015

Measles virus (MV) was classified in 24 genotypes that show a distinct geographic distribution. Genotypes contain multiple distinct lineages. In 2011 large outbreaks of measles occurred in Italy and in many European countries. Aims of this study are to analyze the intra-genotype variability and to follow the importation and the spread of new MV strains in Sicily. A fragment of 450. bps of MV C-terminal nucleoprotein was sequenced from sera of 73 Sicilian patients with symptomatic measles infections, occurred between 2010 and 2011. Five MV strains were D4 genotype and 68 were D8 genotype. The MV/D4 sequences were related to MV/D4-Enfield variant. Two lineages of MV/D8 genotypes, related to M…

The Prevalence of Sexual Violence: Results From a Population-Based Sample

2016

BACKGROUND: Sexual violence can cause severe mental and bodily harm. This is the first study of a population-based sample in Germany to assess both the frequency of the subjects' having experienced sexual violence and the frequency of their having manifested sexually aggressive behavior themselves. METHODS: 2513 persons (of whom 2422 were over age 18 and 91 were aged 14 to 18) were asked about their experiences with sexual violence in the past 12 months, either as the person committing sexual violence or as the victim of sexual violence at the hands of other adults or similarly aged adolescents. RESULTS: 0.6% (n = 6) of the men and 1.2% (n = 16) of the women surveyed, and ca. 5% (n = 4) of …

Dental aesthetics, self-awareness, and oral health-related quality of life in young adults.

2004

The aim of the present study was to explore the putative relationship between dental aesthetics and oral health-related quality of life (OHRQoL), taking into consideration the potential direct and moderating influence of private and public self-consciousness. The subjects of this cross-sectional survey were 148 university students. Dental aesthetics were assessed by means of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN). OHRQoL was estimated using a modification of the scales 'social appearance concern' and 'appearance disapproval', and a novel dental self-confidence scale. In addition, the private and public self-consciousness scales were used. Two-factor a…

Commuting Accidents in the German Chemical Industry

2010

Due to accident severity and the extent of claim payments commuting accidents are a significant expense factor in the German industry. Therefore the aim of the present study was the identification of risk factors for commuting accidents in a German chemical company. A retrospective analysis of commuting accidents recorded between 1990 and 2003 was conducted in a major chemical company in Germany. A logistic regression-model was calculated in order to determine factors influencing the duration of work inability as a result of commuting accidents. The analysed data included 5,484 employees with commuting accidents. Cars (33.1%) and bicycles (30.5%) were the most common types of vehicles used …

Socioeconomic inequalities in the impact of tobacco control policies on adolescent smoking. A multilevel study in 29 European countries

2016

Abstract Introduction There are concerns that tobacco control policies may be less effective in reducing smoking among disadvantaged socioeconomic groups and thus may contribute to inequalities in adolescent smoking. This study examines how the association between tobacco control policies and smoking of 15-year-old boys and girls among 29 European countries varies according to socioeconomic group. Methods Data were used from the Health Behaviour in School-aged Children (HBSC) study conducted in 2005/2006 comprising 50,338 adolescents aged 15 years from 29 European countries. Multilevel logistic regression analyses were conducted to assess the association of weekly smoking with components of…

Peginterferon-Α_2B plus ribavirin is more effective than peginterferon-Α_2A plus ribavirin in menopausal women with chronic hepatitis C.

2012

Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naïve patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44.2% of Peg-…
