A descriptive study of undergraduate contraceptive attitudes among students at the University of New Hampshire

PURPOSE: The purpose of this study was to examine and to understand undergraduate students’ contraceptive attitudes and its effects on contraceptive use to further enhance the education regarding unwanted pregnancies and sexually transmitted diseases (STDs). DESIGN AND METHODS: A descriptive study to understand contraceptive attitudes while exploring demographics and sexual behaviors as well as the incorporation of the Contraceptive Attitude Scale (CAS). The researchers utilized an online survey system to distribute surveys electronically. RESULTS: Most students had a positive attitude regarding contraception. IMPLICATIONS: Nurses at college health facilities can focus on educating the college population since their age group is likely to engage in risky behavior

Alterations to Melanocortinergic, GABAergic and Cannabinoid Neurotransmission Associated with Olanzapine-Induced Weight Gain

Background/Aim: Second generation antipsychotics (SGAs) are used to treat schizophrenia but can cause serious metabolic side-effects, such as obesity and diabetes. This study examined the effects of low to high doses of olanzapine on appetite/ metabolic regulatory signals in the hypothalamus and brainstem to elucidate the mechanisms underlying olanzapineinduced obesity. Methodology/Results: Levels of pro-opiomelanocortin (POMC), neuropeptide Y (NPY) and glutamic acid decarboxylase (GAD65, enzyme for GABA synthesis) mRNA expression, and cannabinoid CB1 receptor (CB1R) binding density (using [ 3 H]SR-141716A) were examined in the arcuate nucleus (Arc) and dorsal vagal complex (DVC) of female Sprague Dawley rats following 0.25, 0.5, 1.0 or 2.0 mg/kg olanzapine or vehicle (36/day, 14-days). Consistent with its weight gain liability, olanzapine significantly decreased anorexigenic POMC and increased orexigenic NPY mRNA expression in a dose-sensitive manner in the Arc. GAD65 mRNA expression increased and CB1R binding density decreased in the Arc and DVC. Alterations to neurotransmission signals in the brain significantly correlated with body weight and adiposity. The minimum dosage threshold required to induce weight gain in the rat was 0.5 mg/kg olanzapine. Conclusions: Olanzapine-induced weight gain is associated with reduced appetite-inhibiting POMC and increased NPY. This study also supports a role for the CB1R and GABA in the mechanisms underlying weight gain side-effects, possibly b
