Factors associated with second-hand smoke exposure in non-smoking pregnant women in Spain: self-reported exposure and urinary cotinine levels.
2014
The aim of this study was to evaluate the main sources of and sociodemographic factors associated with second-hand smoke (SHS) exposure, assessed both by questionnaire and by urinary cotinine (UC) levels, in non-smoking pregnant women. We conducted a cross-sectional study in pregnant women from 4 different regions in Spain. A total of 1783 non-smoking pregnant women completed a questionnaire about their previous smoking habit and SHS exposure in their 3rd trimester of pregnancy and provided a urine sample for measuring UC levels. We used logistic regression models to assess the relationship between several sociodemographic variables and some potential sources of SHS exposure. In addition, w…
Cardiorespiratory Fitness Is Associated With Drop Out From Sport in Norwegian Adolescents. A Longitudinal Study
2020
Several studies indicate that participation in organized sport may result in higher physical activity levels among youth which are associated with high levels of cardiorespiratory fitness. However, no study has examined whether cardiorespiratory fitness (VO2peak) is associated with drop out from sport. The study was a 5-year longitudinal study which followed a sample of adolescents, with measures of cardiorespiratory fitness, weight and height between the age of 14 and 19 yrs. Self-reported data about participation in sport, active commuting and physical activity level were also included. Through logistic regression analyses we found a positive association between cardiorespiratory fitness …
Pregnancy and internet: sociodemographic and geographic differences in e-health practice. Results from an Italian multicenter study
2015
Since the new millennium, the number of e-health users has significantly increased. Among these, a particular category of people who are interested by this phenomenon is the one of pregnant women. The aim of the present study is to assess the sociodemographic and geographic differences existing in a sample of Italian pregnant women who search for information on the web.Multicenter cross-sectional survey.The present study has been conducted from November 2011 to September 2012, in seven Italian cities, located in the North, in the Centre and in the South of Italy. Data were collected through an anonymous questionnaire, administered in waiting rooms of outpatient departments by trained medica…
Healthcare students’ flu vaccine uptake in the last 5 years and future vaccination acceptance: is there a possible association?
2020
Background:Despite the free-of-charge offer of influenza vaccines to at-risk subgroups, vaccine coverage remains low and far from the target, probably due to the false myths and misperceptions. We aimed to explore the healthcare students’ vaccination behavior and beliefs to find any association between vaccination uptake during the last 5 years and future vaccination acceptance.Study design:A multicentre cross-sectional study.Methods:From Oct 2017 to Nov 2018, the Italian healthcare students from 14 different universities in 2017/2018 were enrolled, through an online and anonymous questionnaire previously validated. Absolute and relative frequencies were calculated and Pearson's Chi-square …
Increasing the probability of selecting chromosomally normal embryos by time-lapse morphokinetics analysis
2013
Objective To study the differences in the cleavage time between chromosomally normal and abnormal embryos and to elaborate an algorithm to increase the probability of noninvasively selecting chromosomally normal embryos. Design Retrospective cohort study. Setting University-affiliated infertility center. Patient(s) Preimplantation genetic screening patients (n = 125; n=77 with ET), including cases of repeated implantation failure or recurrent miscarriage. A total of 504 embryos were analyzed. Intervention(s) Embryo culture within a time-lapse system. Main Outcome Measure(s) Kinetic variables included the time to 2 (t2), 3 (t3), 4 (t4), and 5 (t5) cells as well as the length of the second (c…
Predictive factors of transarterial chemoembolisation toxicity in unresectable hepatocellular carcinoma
2013
Abstract Background Transarterial chemoembolisation (TACE) is an effective treatment for unresectable hepatocellular carcinoma (HCC), but can cause severe toxicity. Aim To identify predictive factors of severe TACE-related toxicity in patients with unresectable HCC. Methods All HCC patients who underwent TACE at the Dijon University Hospital between 2008 and 2011 were included in this retrospective study. Severe TACE-related toxicity was defined as the occurrence of any adverse event grade ≥4, or any adverse event that caused a prolongation of hospitalisation of >8 days, or any additional hospitalisation within 1 month after TACE. Factors predicting toxicity were identified using a logistic…
Proton pump inhibitors increase risk of bone fractures in men with cirrhosis: a population-based study
2020
Bone fractures are a frequent complication in patients with cirrhosis. Proton pump inhibitors (PPIs) are among the most frequently prescribed medications and may impair bone quality and quantity.To investigate whether PPI use predisposes patients with cirrhosis to bone fractures.We performed a population-based case-control study exploring a sample of patients with cirrhosis derived from the Disease Analyzer database. In total, 1795 cirrhotic patients with fractures were compared to 10 235 cirrhotic patients without fractures. PPI use overall and the cumulative PPI dose 5 years prior to the index date were analysed. To estimate the association between PPI use and fractures, logistic regressi…
Physical injury and depression in six low- and middle-income countries: A nationally representative study.
2019
BACKGROUND: Studies on the association between physical injury and depression in low- and middle-income countries (LMICs) are scarce. Therefore, our goal was to analyze the association between physical injury and depression using nationally representative data from six LMICs. METHODS: Cross-sectional data from the Study on Global Ageing and Adult Health (SAGE) survey (2007-2010) were analyzed (N?=?42,489). Questions based on the World Mental Health Survey version of the Composite International Diagnostic Interview were used for the endorsement of past 12-month DSM-IV depression. Any injury in our analysis referred to having experienced traffic injury or other injury in the past 12 months. M…
Dietary inflammatory index and cancer risk in the elderly: A pooled-analysis of Italian case-control studies
2019
Abstract Objectives The aim of this study was to evaluate whether the association between the inflammatory potential of one's diet and cancer risk varies across age groups in a population characterized by widespread use of the Mediterranean diet. Methods We analyzed data from a network of case-control studies conducted in Italy between 1991 and 2014. The studies included cancers of the oral cavity (n = 509), pharynx (n = 436), nasopharynx (n = 198), larynx (n = 459), esophagus (n = 304), stomach (n = 230), colon (n = 1225), rectum (n = 728), liver (n = 184), pancreas (n = 326), breast (n = 2569), endometrium (n = 454), ovary (n = 1031), prostate (n = 1294), kidney (n = 767), and bladder (n …
