[EX Q]: Multidrug resistant (MDR) uropathogens are increasing in prevalence and may contribute to significant morbidity after percutaneous nephrolithotomy (PCNL). We investigate the presence of MDR bacteriuria and occurrence of postoperative infectious complications in patients who underwent PCNL at our institution.', 'Retrospective review was performed of 81 patients undergoing PCNL by a single surgeon (RLS) between 2009 and 2013. Patient demographics, comorbidities, stone parameters on imaging, and microbial data were compiled. MDR organisms were defined as resistant to three or more of the American Urological Association Best Practice Statement antimicrobial classes for PCNL. Postoperative complications were graded by Clavien score and European Association of Urology infection grade. Univariate comparisons were analyzed between patients with and without a postoperative infectious complication. Multivariate logistic regression was performed to determine significant predictor variables for postoperative infectious complications.', 'Of the 81 patients undergoing PCNL, 41/81 (51%) had positive preoperative urine culture, 24/81 (30%) had positive MDR urine culture, and 16/81 (19%) had a postoperative infectious complication. Multivariate analysis revealed a positive preoperative MDR urine culture significantly increased the risk of postoperative infectious complication (odds ratio [OR]=4.89, 95% confidence interval [CI] 1.134-17.8, P=0.016). The presence of more than one access tract during PCNL also predicted for infectious complications (OR=7.5, 95% CI 2.13-26.4, P=0.003) Of the 16 patients with a postoperative infection 3 (18%) had postoperative urine cultures discordant with the preoperative urine cultures.

[EX Q]: Recent randomized trials suggest that intensive glycaemic control fails to reduce heart failure-related events in patients with diabetes. The molecular cues underlying persistent myocardial damage despite normoglycaemia restoration remain elusive. MicroRNAs (miRNAs), a class of small non-coding RNAs, orchestrate transcriptional programs implicated in adverse cardiac remodelling. The present study investigates whether miRNAs participate to hyperglycaemic memory in the diabetic heart.', 'miRNA landscape was assessed by Mouse miRNome miRNA PCR Arrays in left ventricular specimens collected from 4-month-old streptozotocin-induced diabetic mice, with or without intensive glycaemic control by slow-release insulin implants. A dysregulation of 316 out of 1008 total miRNAs was observed in the diabetic hearts when compared with controls. Of these, 209 were up-regulated and 107 were down-regulated by >2.0-fold. Interestingly enough, the expression of 268 of those miRNAs remained significantly altered in diabetic mice even after subsequent normoglycaemia. Ingenuity pathway analysis revealed that dysregulated miRNAs were implicated in myocardial signalling networks triggering apoptosis (miR-320b, miR-378, miR-34a), fibrosis (miR-125b, miR-150, miR-199a, miR-29b, miR30a), hypertrophic growth (miR-1, miR-150, miR-199a, miR-133a, miR-214, miR-29a, miR-125b, miR-221, miR-212), autophagy (miR-133a, miR-221, miR-212, miR30a), oxidative stress (miR-221, miR-146a, miR-34a, miR-210, miR-19b, miR-125b, miR27a, miR-155), and heart failure (miR-423, miR-499, miR-199a), respectively.

[EX Q]: Disturbed sleep is associated with mood disorders. Both depression and insomnia may increase the risk of disability retirement. The longitudinal links among insomnia, depression and work incapacity are poorly known.', 'We examined association of self-reported sleep quality with incident symptoms of depression and disability retirement due to depressive disorders in a longitudinal population-based sample of twins (n=12,063 individuals). These adults were categorized by their sleep quality in 1975 and 1981, excluding individuals with depressed mood in 1975/1981. The outcomes were the Beck Depression Inventory (BDItot) and its subscale Negative Attitudes Towards Self (BDINATS) in 1990 as dichotomized measures, and the incidence of disability retirement due to depressive disorder during 1991-2004.', 'Onset of poor sleep between 1975 and 1981 predicted incident depression (BDItot OR=4.5, 95% CI: 2.7-7.4, BDINATS OR=2.0, 95% CI: 1.4-2.7), while persistent poor sleep showed somewhat weaker effects (BDItot; OR=2.5, 95% CI: 1.0-6.0, BDINATS OR=1.9, 95% CI: 1.1-3.3). Among those with few recent stressful life events, onset of poor sleep predicted strongly depression (BDINATS OR=9.5, 95% CI: 3.7-24.2). Likewise onset of poor sleep by 1981 increased the risk of disability retirement due to depression (OR=2.9, 95% CI: 1.8-4.9) with a similar risk among those with persistent poor sleep (OR=2.7, 95% CI: 1.3-5.7).
