RESUMO

Infertility affects about 15% of the population and male factors only are responsible for ~25-30% of cases of infertility. Currently, the etiology of suboptimal semen quality is poorly understood, and many environmental and genetic factors, including oxidative stress, have been implicated. Oxidative stress is an imbalance between the production of free radicals, or reactive oxygen species (ROS), and the capacity of the body to counteract their harmful effects through neutralization by antioxidants. The purpose of this review, by employing the joint expertise of international researchers specialized in nutrition and male fertility areas, is to update the knowledge about the reproductive consequences of excessive ROS concentrations and oxidative stress on the semen quality and Assisted Reproduction Techniques (ART) clinical outcomes, to discuss the role of antioxidants in fertility outcomes, and finally to discuss why foods and dietary patterns are more innocuous long term solution for ameliorating oxidative stress and therefore semen quality results and ART fertility outcomes. Since this is a narrative review and not a systematic/meta-analysis, the summarized information in the present study should be considered cautiously.

RESUMO

Background: During 2009, new guidelines for the treatment of diabetic ketoacidosis were published by the American Diabetes Association. Aim: To assess the impact of new treatment guidelines on the evolution of patients treated for diabetic ketoacidosis (KAD). Patients and Methods: Anonymous data was obtained from computational medical records of patients treated for KAD at our institution two years before (“Traditional Protocol”) and TWO years after (“ADA-2009 Protocol”) the publication of the 2009 American Diabetes Association (ADA) KAD guidelines. Results: Twenty three patients aged 36.5 ± 15.1 years were treated with the traditional method and 23 patients aged 44.4 ± 21.1 years were treated following 2009 ADA guidelines. Among patients treated with the traditional protocol and treated following ADA 2009 guidelines, the diabetes type 1/type 2 ratio was18/5 and 19/16 respectively (p = NS), the glycosylated hemoglobin on admission was 12.6 ± 2.5 and 14.3 ± 2.7% respectively (p = 0.03), minimal blood pH was 7.15 ± 0.14 and 7.19 ± 0.09 respectively (p = NS), bicarbonate was required in seven and no patient respectively (p = 0.01), hypokalemia < 3.5 mEq/L occurred in 78.2 and 48.5% of patients (p = 0.03), the lapse until resolution was 28.7 ± 28.0 and 28.8 ± 20.6 hours (p = NS). Only one patient, treated following ADA 2009 guidelines, died. Conclusions: Introduction of the ADA-2009 protocol for the treatment of KAD resulted in decrease in the use of intravenous bicarbonate and a reduction in the incidence of hypokalemia. There was no impact neither in the lapse until resolution or lethality.

RESUMO

OBJECTIVE: The health care workforce is evolving and part-time practice is increasing. The objective of this work is to determine the relationship between part-time status, workplace conditions, and physician outcomes. DESIGN: Minimizing error, maximizing outcome (MEMO) study surveyed generalist physicians and their patients in the upper Midwest and New York City. MEASUREMENTS AND MAIN RESULTS: Physician survey of stress, burnout, job satisfaction, work control, intent to leave, and organizational climate. Patient survey of satisfaction and trust. Responses compared by part-time and full-time physician status; 2-part regression analyses assessed outcomes associated with part-time status. Of 751 physicians contacted, 422 (56%) participated. Eighteen percent reported part-time status (n = 77, 31% of women, 8% of men, p < .001). Part-time physicians reported less burnout (p < .01), higher satisfaction (p < .001), and greater work control (p < .001) than full-time physicians. Intent to leave and assessments of organizational climate were similar between physician groups. A survey of 1,795 patients revealed no significant differences in satisfaction and trust between part-time and full-time physicians. CONCLUSIONS: Part-time is a successful practice style for physicians and their patients. If favorable outcomes influence career choice, an increased demand for part-time practice is likely to occur.
