question:
Organ/space surgical site infections (OSIs) constitute an important postoperative metric. We sought to assess the impact of a previously described air leak test (ALT) on the incidence of OSI following major hepatectomies.', 'A single-institution hepatobiliary database was queried for patients who underwent a major hepatectomy without biliary-enteric anastomosis between January 2009 and June 2015. Demographic, clinicopathologic, and intraoperative data-including application of ALT-were analyzed for associations with postoperative outcomes, including OSI, hospital length of stay (LOS), morbidity and mortality rates, and readmission rates.', 'Three hundred eighteen patients were identified who met inclusion criteria, of whom 210 had an ALT. ALT and non-ALT patients did not differ in most disease and treatment characteristics, except for higher rates of trisegmentectomy among ALT patients (53 vs. 34%, p=0.002). ALT patients experienced lower rates of OSI and 90-day morbidity than non-ALT patients (5.2 vs. 13.0%, p=0.015 and 24.8 vs. 40.7%, p=0.003, respectively). In turn, OSI was the strongest independent predictor of longer LOS (OR=4.89; 95% CI, 2.80-6.97) and higher rates of 30- (OR=32.0; 95% CI, 10.9-93.8) and 45-day readmissions (OR=29.4; 95% CI, 10.2-84.6).

question:
The hormone melatonin regulates the sleep and this pineal hormone is synthesized in the organism from the amino acid tryptophan. It is known that breast-fed babies have better sleep patterns and a better entrained sleep/wake cycle than bottle-fed babies (adapted formula).', "To compare the circadian rhythm of 6-sulfatoxymelatonin (aMT6s)--the metabolite of melatonin excreted in the urine--in urine of bottle-fed and breast-fed children, and relate it to the circadian rhythm of tryptophan in breast milk, also evaluating the possible effects on the baby's night-time rest.", '16 infants of 12 weeks of age were studied, divided into two groups depending on their exclusively natural or artificial feeding. The circadian rhythm of 6-sulfatoxymelatonin in urine was measured for the two groups of infants and for the breast-feeding mothers. In the breast milk, the circadian rhythm of the amino acid tryptophan was measured. The rest of the infants was tested by wrist actimeters for a week and the sleep parameters of the infants were measured and evaluated.', 'The tryptophan in the breast milk presented a circadian rhythm with acrophase at around 03:00. This affected the 6-sulfatoxymelatonin circadian rhythm with acrophase at 06:00 in the breast-fed infants, and also promoted nocturnal sleep. Assumed sleep, actual sleep, and sleep efficiency were significantly increased in the breast fed infants with respect the formula fed infants.

question:
The relationship between self-reported lifetime traumatic brain injury (TBI) and drug and alcohol use and associated harms was examined using an epidemiological sample of Canadian adolescents.', 'Data were derived from a 2011 population-based cross-sectional school survey, which included 6383 Ontario 9th-12th graders who self-completed anonymous self-administered questionnaires in classrooms. Traumatic brain injury was defined as loss of consciousness for at least 5 minutes or a minimum 1-night hospital stay due to symptoms.', 'Relative to high schoolers without a history of TBI, those who acknowledged having a TBI in their lifetime had odds 2 times greater for binge drinking (5+ drinks per occasion in the past 4 weeks), 2.5 times greater for daily cigarette smoking, 2.9 times greater for nonmedical use of prescription drugs, and 2.7 times greater for consuming illegal drug in the past 12 months. Adolescents with a history of TBI had greater odds for experiencing hazardous/harmful drinking (adjusted odds ratio [aOR] = 2.3), cannabis problems (aOR = 2.4), and drug problems (aOR = 2.1), compared with adolescents who were never injured.
