Gender-specific association between childhood adversities and smoking in adulthood: findings from a population-based study.

OBJECTIVE: To investigate gender-specific differences between individual adverse childhood experiences (ACEs) and smoking behaviours in adulthood; while controlling for several known risk factors, including adult health behaviours, adult mental health, adult socio-economic indicators and social support. METHODS: Data were obtained from the 2010 Behavioral Risk Factor Surveillance System. The sample included 19,356 individuals (11,506 females and 7850 males) aged ≥18 years who were asked questions about their ACEs. Using logistic regression, the independent factors associated with ever smoking and current smoking were determined. RESULTS: Childhood physical abuse was associated with ever smoking for both males and females. Neither sexual abuse nor verbal abuse were significantly associated with ever smoking for males, but they were for females [odds ratio (OR) 1.36, 95% confidence interval (CI) 1.13-1.63 and OR 1.14, 95% CI 1.02-1.27, respectively]. For both genders, childhood exposure to parental separation or divorce, household drug abuse or household problem drinking, were significantly associated with ever smoking. CONCLUSION: These findings underscore the need for future research that investigates gender-specific differences, and the possible mechanisms, linking individual ACEs and smoking behaviours.

Initial experience with the HydroSonics instrument to soften cataracts before phacoemulsification.

An ultrasonically driven needle placed into the body of the nucleus, with subsequent injection of balanced salt solution (BSS), can be used to fragment the nucleus into sections or lamellae that can potentially be emulsified with greater ease and less ultrasound energy delivered to the eye. This separation of the nucleus has been designated hydrodelineation. The six surgeons participating in this study subjectively reported that the use of hydrodelineation facilitated phacoemulsification, on average, in 91% of their cases. Review of study data indicated that significantly less ultrasound time and cumulative displayed energy were noted in phacoemulsification of grade 2+ and 3+ cataracts after hydrodelineation than in cases in which hydrodelineation was not performed. The results in cases performed with and without hydrodelineation were statistically equivalent in complications and postoperative patient outcomes.
