Objectives: To evaluate: (1) the associations between maternal psychological stress, distress and low birth weight (LBW), prematurity and intrauterine growth retardation (IUGR); (2) the interactions between maternal stress, distress and smoking, alcohol and coffee intake; (3) the prevalences of stress and distress in pregnancy.Design: Longitudinal cohort(More)
OBJECTIVE/HYPOTHESIS To compare cold and mixed (electrocautery tonsillectomy with curettage adenoidectomy) adenotonsillectomies in children in terms of hospital medications' and materials' costs, surgical time, aspirated blood volume, and postoperative pain. STUDY DESIGN Randomized clinical trial in community hospitals. METHODS Seventy-two patients aged(More)
Four 1.5-year-old, male, Murrah buffalos were maintained during eight months without direct solar exposure during a study of copper toxicosis. Four days after solar exposure, all buffalos presented clinical manifestations consistent with acute photosensitization, including anorexia, apathy, loss of body weight, and generalized cutaneous lesions. Gross(More)
The susceptibility of cattle and buffalos to chronic copper poisoning (CCP) was compared by using cattle (n=10) and buffalo (n=10) steers distributed into two copper supplemented (n=6) and two control (n=4) groups. Supplemented animals received 2 mg copper (Cu)/kg body weight daily for one week, with an additional 2 mg weekly until the end of the experiment(More)
BACKGROUND Little is known about the reasoning mechanisms used by physicians in decision-making and how this compares to diagnostic clinical practice guidelines. We explored the clinical reasoning process in a real life environment. METHOD This is a qualitative study evaluating transcriptions of sixteen physicians' reasoning during appointments with(More)
OBJECTIVES/HYPOTHESIS To identify the association between surgeon/hospital volume with outcomes in surgical treatment for obstructive sleep apnea (OSA) in a nationally representative sample. We hypothesized that surgeons/hospitals with lower patient volumes would have: higher mortality rates, longer hospital length of stay (LOS), and higher postoperative(More)
Several morbid conditions may necessitate extensive intestinal resection, leading to short-bowel syndrome. When clinical treatment becomes inefficient, a surgical approach is necessary. Distal colon interposition is one of the viable techniques. The interposition of colon segments between remnants of the small bowel improved lifestyle, increased transit(More)
