Question: Context: To assess the effect of newborn circumcision on the incidence and medical costs of urinary tract infection (UTI) during the first year of life for patients in a large health maintenance organization.', 'Kaiser Permanente Medical Care Program of Northern California (KPNC).', 'The population consisted of members of KPNC. The study group consisted of a cohort of 28 812 infants delivered during 1996 at KPNC hospitals; of the 14 893 male infants in the group, 9668 (64.9%) were circumcised. A second cohort of 20 587 infants born in 1997 and monitored for 12 months was analyzed to determine incidence rates.', 'Retrospective study of all infants consecutively delivered at 12 facilities.', 'Diagnosis of UTI was determined from the KPNC computerized database using the International Classification of Diseases, Ninth Revision code for inpatients and KPNC Outpatient Summary Clinical Record codes for outpatients. A sample of 52 patient charts was reviewed to confirm the International Classification of Diseases, Ninth Revision and KPNC Outpatient Summary Clinical Record codes and provide additional data.', 'Infants <1 year old who were born in 1996 had 446 UTIs (292 in females; 154 in males); 132 (86%) of the UTIs in males occurred in uncircumcised boys. The mean total cost of managing UTI was 2 times as high in males ($1111) as in females ($542). This higher total cost reflected the higher rate of hospital admission in uncircumcised males with UTIs (27.3%) compared with females (7.5%); mean age at hospitalization for UTI was 2.5 months old for uncircumcised boys and 6.5 months old for girls. In 1996, total cost of managing UTI in uncircumcised males ($155 628) was 10 times higher than for circumcised males ($15 466) despite the fact that uncircumcised males made up only 35.1% of the male patient base in 1996, reflecting the more frequent occurrence of UTI in uncircumcised males (132 episodes) than in circumcised males (22 episodes), and the larger number of hospital admissions in uncircumcised males (38) than in circumcised males (4). The incidence of UTI in the first year of life was 1:47 (2.15%) in uncircumcised males, 1:455 (.22%) in circumcised males, and 1:49 (2. 05%) in females. The odds ratio of UTI in uncircumcised:circumcised males was 9.1:1.
Answer: Newborn circumcision results in a 9. 1-fold decrease in incidence of UTI during the first year of life as well as markedly lower UTI-related medical costs and rate of hospital admissions. Newborn circumcision during the first year of life is, thus, a valuable preventive health measure, particularly in the first 3 months of life, when uncircumcised males are most likely to be hospitalized with severe UTI.

Answer: Does newborn circumcision decrease incidence and costs of urinary tract infections during the first year of life?


Question: Context: Dyschloremia is common in critically ill patients, although its impact has not been well studied. We investigated the epidemiology of dyschloremia and its associations with the incidence of acute kidney injury and other intensive care unit outcomes.', 'This is a single-center, retrospective cohort study at Mayo Clinic Hospital-Rochester. All adult patients admitted to intensive care units from January 1st, 2006, through December 30th, 2012 were included. Patients with known acute kidney injury and chronic kidney disease stage 5 before intensive care unit admission were excluded. We evaluated the association of dyschloremia with ICU outcomes, after adjustments for the effect of age, gender, Charlson comorbidity index and severity of illness score.', 'A total of 6,025 patients were enrolled in the final analysis following the implementation of eligibility criteria. From the cohort, 1,970 patients (33%) developed acute kidney injury. Of the total patients enrolled, 4,174 had a baseline serum chloride. In this group, 1,530 (37%) had hypochloremia, and 257 (6%) were hyperchloremic. The incidence of acute kidney injury was higher in hypochloremic and hyperchloremic patients compared to those with a normal serum chloride level (43% vs.30% and 34% vs. 30%, respectively; P < .001). Baseline serum chloride was lower in the acute kidney injury group vs. the non-acute kidney injury group [100 mmol/L (96-104) vs. 102 mmol/L (98-105), P < .0001]. In a multivariable logistic regression model, baseline serum chloride of ≤94 mmol/L found to be independently associated with the risk of acute kidney injury (OR 1.7, 95% CI 1.1-2.6; P = .01).
Answer: Dyschloremia is common in critically ill patients, and severe hypochloremia is independently associated with an increased risk of development of acute kidney injury.

Answer: Does dyschloremia be a Risk Factor for the Development of Acute Kidney Injury in Critically Ill Patients?


Question: Context: In Parkinson's disease, striatal dopamine transporter (DAT) binding and cardiac sympathetic function are disturbed. In addition, heart rate (HR)-corrected cardiac repolarisation time (QTc interval), which is partly under autonomic control, is prolonged. Whether there is physiological coupling between striatal DAT binding and QTc time (QTc-DAT relation) is not known. The purpose of this study is to evaluate QTc-DAT relation in healthy young adults.", "Thirty-five participants (18 women, age 26.4+/-1.8 years; mean+/-SD) were studied with iodine-123 labelled 2beta-carbomethoxy-3beta-(4-iodophenyl) nortropane single photon emission tomography. Signal-averaged ECG was recorded at rest from each participant. QTc interval was computed with Bazett's correction and with the approach by Karjalainen, getting QTc and QTk intervals, respectively.", 'Mean striatal DAT binding, as (striatum-cerebellum)/cerebellum, was 2.63+/-0.31. Mean HR, QT, QTc and QTk intervals were 66+/-9 bpm, 340+/-25 ms, 354+/-18 ms and 351+/-16 ms, respectively. HR-QT correlation was -0.63, P value of less than 0.001. HR was not related to striatal DAT binding. QTc-DAT and QTk-DAT relations were significant, r = -0.50, P = 0.004 and r = -0.59, P = 0.0002, respectively. In linear regression model, striatal DAT binding explained 35% of the variance of QTk interval (95% confidence interval: -46.9 to -13.0, P = 0.0002).
Answer: This study suggests significant physiological QTc-DAT relation in young healthy adults. QTc interval measurements might carry diagnostically important information in clinical conditions, which have an effect on both striatal DAT binding and cardiac sympathetic function.

Answer:
Are cardiac repolarization and striatal dopamine transporter function interrelated?
