[Q]: Previous studies regarding the outcome of laparoscopic cholecystectomy (LC) in men have reported inconsistent findings. We conducted this prospective study to test the hypothesis that the outcome of LC is worse in men than women.', 'Between 1997 and 2002, a total of 391 consecutive LCs were performed by a single surgeon at King Fahd Hospital of the University. We collected and analyzed data including age, gender, body mass index (kg/m(2)), the American Society of Anesthesiologists (ASA) class, mode of admission (elective or emergency), indication for LC (chronic or acute cholecystitis [AC]), comorbid disease, previous abdominal surgery, conversion to open cholecystectomy, complications, operation time, and length of postoperative hospital stay.', 'Bivariate analysis showed that both genders were matched for age, ASA class and mode of admission. The incidences of AC (P = 0.003) and comorbid disease (P = 0.031) were significantly higher in men. Women were significantly more obese than men (P < 0.001) and had a higher incidence of previous abdominal surgery (P = 0.017). There were no statistical differences between genders with regard to rates of conversion (P = 0.372) and complications (P = 0.647) and operation time (P = 0.063). The postoperative stay was significantly longer in men than women (P = 0.001). Logistic regression analysis showed that male gender was not an independent predictor of conversion (Odds ratio [OR] = 0.37 and P = 0.43) or complications (OR = 0.42, P = 0.42). Linear regression analysis showed that male gender was not an independent predictor of the operation time, but was associated with a longer postoperative stay (P = 0.02).

[Q]: Several viruses have been recently isolated from Mediterranean phlebotomine sand flies; some are known to cause human disease while some are new to science. To monitor the Phlebotomus-borne viruses spreading, field studies are in progress using different sand fly collection and storage methods. Two main sampling techniques consist of CDC light traps, an attraction method allowing collection of live insects in which the virus is presumed to be fairly preserved, and sticky traps, an interception method suitable to collect dead specimens in high numbers, with a risk for virus viability or integrity. Sand flies storage requires a "deep cold chain" or specimen preservation in ethanol. In the present study the influence of sand fly collection and storage methods on viral isolation and RNA detection performances was evaluated experimentally.', 'Specimens of laboratory-reared Phlebotomus perniciosus were artificially fed with blood containing Toscana virus (family Bunyaviridae, genus Phlebovirus). Various collection and storage conditions of blood-fed females were evaluated to mimic field procedures using single and pool samples. Isolation on VERO cell cultures, quantitative Real time-Retro-transcriptase (RT)-PCR and Nested-RT-PCR were performed according to techniques commonly used in surveillance studies.', 'Live engorged sand flies stored immediately at -80 °C were the most suitable sample for phlebovirus identification by both virus isolation and RNA detection. The viral isolation rate remained very high (26/28) for single dead engorged females frozen after 1 day, while it was moderate (10/30) for specimens collected by sticky traps maintained up to 3 days at room temperature and then stored frozen without ethanol. Opposed to viral isolation, molecular RNA detection kept very high on dead sand flies collected by sticky traps when left at room temperature up to 6 days post blood meal and then stored frozen in presence (88/95) or absence (87/88) of ethanol. Data were confirmed using sand fly pools.

[Q]: Gastroesophageal reflux disease (GERD) with proton pump inhibitor (PPI) use is associated with an increased risk of osteoporosis. The risk of hip fracture is not increased in GERD patients with PPI use.', 'The relationship between GERD with PPI treatment and the risk of osteoporosis is unclear. We aimed to determine the risk of developing osteoporosis in patients diagnosed with GERD.', 'Patients diagnosed with GERD and received PPI treatment between 2000 and 2010 were identified from the Longitudinal Health Insurance Database as the study cohort (n\u2009=\u200910,620), which was frequency matched with the comparison cohort (n\u2009=\u200920,738) sampled from the general population according to age, sex, index year, and comorbidities. Both cohorts were followed until the end of 2011. The risk of osteoporosis was evaluated in both groups by using Cox proportional hazards regression models.', 'The GERD patients with PPI treatment had a greater incidence (31.4 vs 20.7 per 1000 person-year; crude hazard ratio [cHR] 1.51; 95\xa0% confidence interval [CI] 1.40-1.63) and a higher risk (adjusted HR [aHR] 1.50; 95\xa0% CI 1.39-1.62) of osteoporosis than that of the comparison cohort. However, the overall incidence of hip fracture was not different between the GERD with PPI use and the control cohorts (aHR 0.79; 95\xa0% CI 0.53-1.18).
