COVID-19 lockdown: The relationship between trait impulsivity and addictive behaviors in a large representative sample of Italian adults

open9noBackground: The importance of trait impulsivity in development, continuation and escalation of addictive behaviors has long been recognized. Methods: A cross-sectional population-based survey was conducted during the COVID-19 lockdown on 6003 Italian adults aged 18–74 years, representative of the Italian general population, to investigate the relationship between impulsivity (Barratt Impulsiveness Scale – BIS) and selected addictive behaviors (gambling habits, smoking status, cannabis use, average alcohol daily use). Results: A statistically significant relationship was found between motor impulsivity and starting/increasing drinking and increasing gambling (high vs. low motor impulsivity: multivariate odds ratio, OR=3.12; 95% confidence interval, CI: 1.45–6.74; p for trend=0.004 for start and OR=1.53; 95% CI: 1.26–1.86; p for trend<0.001 for increase drinking, respectively; OR=2.09; 95% CI: 1.41–3.12; p for trend<0.001 for increasing gambling). Limitations: Potential information and recall bias. The necessity to limit the length of the questionnaire not to reduce the quality of the answers of study participants. Conclusions: The multifaceted nature of impulsivity, potentially either cause or effect, hampers the understanding of its proper role in addictive behaviors. If confirmed by future longitudinal studies, our findings might support the planning, implementation and monitoring of evidence-based preventive interventions, to reduce addictive behaviors during public health emergencies.openAmerio A.; Stival C.; Lugo A.; Fanucchi T.; Gorini G.; Pacifici R.; Odone A.; Serafini G.; Gallus S.Amerio, A.; Stival, C.; Lugo, A.; Fanucchi, T.; Gorini, G.; Pacifici, R.; Odone, A.; Serafini, G.; Gallus, S

Alcohol drinking and risk of non-Hodgkin's lymphoma

Objective: To analyse the relation between alcohol intake and the risk of non-Hodgkin's lymphoma (NHL). Design: Hospital-based case\u2013control study. Settings: The greater Milan area and the province of Pordenone, Northern Italy. Subjects: Cases were 446 (256 men and 190 women) with histologically confirmed incident NHL, and controls were 1295 (791 men and 504 women) with acute non-neoplastic conditions. Results: Compared to non-drinkers, the odds ratio (OR) was 0.92 for <3 drinks per day, 0.98 for 3\u20136 drinks, and 1.02 for 657 drinks per day. Wine drinking was also not associated with risk, and the OR was 0.85 for drinkers of 657 drinks/day compared to non-drinkers. Beer and spirit intake was also not associated with NHL risk. Conclusions: Our study, based on a population with relatively high alcohol intakes, indicates that there is no appreciable association between intake of various alcoholic beverages and the risk of NHL

Does coffee protect against hepatocellular carcinoma?

We analysed the relation between coffee consumption and hepatocellular carcinoma in two case-control studies conducted between 1984 and 1998 in Italy and Greece, including 834 cases and 1912 controls. Compared to non coffee drinkers, the multivariate odds ratio was 0.7 for drinkers of three or more cups per day

Simulated microgravity induces nuclear translocation of Bax and BCL-2 in glial cultured C6 cells

Alterations in the control of apoptotic processes were observed in cells during space flight or under simulated microgravity, the latter obtained with the 3D-Random Positioning Machine (3D-RPM). Usually the proteins Bax and Bcl-2, act as pro- or anti-apoptotic regulators. Here we investigated the effects of simulated microgravity obtained by the 3D-RPM on cell viability, localization and expression of Bax and Bcl-2 in cultures of glial cancerous cells. We observed for the first time a transient cytoplasmic/nuclear translocation of Bax and Bcl-2 triggered by changing gravity vector. Bax translocates into the nucleus after 1 h, is present simultaneously in the cytoplasm after 6 h and comes back to the cytoplasm after 24 h. Bcl-2 translocate into the nucleus only after 6 h and comes back to the cytoplasm after 24 h. Physiological meaning, on the regulation of apoptotic event and possible applicative outcomes of such finding are discussed

Cigarette tar yield and risk of upper digestive tract cancers: case-control studies from Italy and Switzerland

Background: Tobacco smoking is one of the main risk factors for oral, pharyngeal and oesophageal cancers in developed countries. Information on the role of the tar yield of cigarettes in upper digestive tract carcinogenesis is sparse and needs to be updated because the tar yield of cigarettes has steadily decreased over the last few decades. Patients and methods: We analysed two case-control studies, from Italy and Switzerland, conducted between 1992 and 1999, involving 749 cases of oral and pharyngeal cancer and 1770 controls, and 395 cases of squamous-cell oesophageal carcinoma and 1066 matched controls. Odds ratios (ORs) were estimated by unconditional multiple logistic regression models, including terms for age, sex, study centre, education and alcohol consumption. Results: Based on the brand of cigarettes smoked for the longest time, the multivariate ORs for current smokers compared with never smokers were 6.1 for <20 mg and 9.8 for ≥20 mg tar for oral and pharyngeal neoplasms, and 4.8 and 5.4 for oesophageal cancer, respectively. For the cigarette brand smoked in the previous six months, the ORs for ≥10 mg compared with <10 mg were 1.9 for cancer of the oral cavity and pharynx and 1.8 for oesophageal cancer, after allowance for number of cigarettes and duration of smoking. Conclusions: The present study confirms the direct relationship between the tar yield of cigarettes and upper digestive tract neoplasms, and provides innovative information on lower tar cigarettes, which imply reduced risks compared with higher tar ones. However, significant excess risks were observed even in the lower tar category, thus giving unequivocal indications for stopping smoking as a priority for prevention of upper digestive tract neoplasm
