Background: The representation of minorities among medical students has increased over the past two decades, but diversity among orthopaedic residents lags behind. This phenomenon has occurred despite a recent focus by the American Academy of Orthopaedic Surgeons on the recruitment of minorities and women. Objective: To analyze the impact of recent efforts on diversity in orthopaedic residents in comparison with other surgical specialties from 2006 to 2015. Methods: Data from the American Association of Medical Colleges on residents in surgical specialty programs in the years 2006 to 2015 were analyzed. Linear regression models were used to estimate trends in diversity among orthopaedic residents and residents in other surgical specialties. A mixed model analysis of variance was used to compare rates of diversification among different specialties over time. Results: Female representation in orthopaedic programs increased from 10.9% to 14.4% between 2006 and 2015. However, the rate of increase was significantly lower compared with other specialties (all P < 0.05) studied, except for urology (P = 0.64). Minority representation in orthopaedics averaged 25.6% over the 10-year period. Residents of Hispanic origin in orthopaedic programs increased (P = 0.0003) but decreased for Native Hawaiian/Pacific Islander (P < 0.0001). During the same period, white representation increased (P = 0.004). No significant changes were found in African Americans or Asian American representation. Diversity decreased among orthopaedic residents over the period studied (P = 0.004). Conclusions: Recruitment efforts have not reversed the sex, racial, and ethnic disparities in orthopaedic residents. Orthopaedics has the lowest representation of women and minorities among residencies studied. The rate of increase in women lags behind all surgical subspecialties, except for urology.
Background and objectives: Diarrhea-associated hemolytic uremic syndrome (D؉HUS) is a common cause of acute kidney injury in children. Mutations in alternative pathway (AP) complement regulatory proteins have been identified in severe cases of thrombotic microangiopathy, but the role of the AP in D؉HUS has not been studied. Therefore, we determined whether plasma levels of markers of activation of the AP are increased in D؉HUS and are biomarkers of the severity of renal injury that predict the need for dialysis.Design, setting, participants, & measurements: Patients were randomly selected from among participants in the HUS-SYNSORB Pk trial. Plasma samples were collected on days 1, 4, 7, and 10 after enrollment and day 28 after discharge from the hospital. Levels of two complement pathway products, Bb and SC5b-9, were determined by ELISA.Results: Seventeen children (6 boys and 11 girls; age, 5.4 ؎ 3.5 yr) were studied. Eight (47%) required dialysis support, and two had serious extrarenal events. On the day of enrollment, plasma levels of Bb and SC5b-9 were significantly increased in all patients compared with healthy controls (P < 0.01). The elevated concentrations normalized by day 28 after discharge. Circulating levels of complement pathway fragments did not correlate with severity of renal injury or occurrence of complications.Conclusions: Patients with acute-onset D؉HUS manifest activation of the AP of complement that is temporally related to the onset of disease and that resolves within 1 mo. Therapies to inhibit the AP of complement may be useful in attenuating the severity of renal injury and extrarenal complications.
BackgroundBiobanks have the potential to offer a venue for chronic disease biomarker discovery, which would allow for disease early detection and for identification of carriers of a certain predictor biomarker. To assess the general attitudes towards genetic research and participation in biobanks in the Long Island/Queens area of New York, and what factors would predict a positive view of such research, participants from the NSLIJ hospital system were surveyed.MethodsParticipants were recruited at six hospital centers in the NSLIJ system during the summers of 2009 and again in 2011 (n = 1,041). Those who opted to participate were given a questionnaire containing 22 questions assessing demographics, lifestyle and attitudes towards genetic research. These questions addressed individual participant’s beliefs about the importance of genetic research, willingness to participate in genetic research themselves, and their views on informed consent issues.ResultsRespondents took a generally positive view of genetic research in general, as well as their own participation in such research. Those with reservations were most likely to cite concerns over the privacy of their medical and genetic information. Those who were married tended to view genetic research as important, while those in the younger age group viewed it as less important. Prior blood donation of respondents was found to be a predictor of their approval for genetic research. Demographic factors were not found to be predictive of personal willingness to participate in genetic research, or of approval for the opt-out approach to consent.ConclusionsWhile respondents were generally inclined to approve of genetic research, and those who disapproved did not do so based on an underlying moral objection to such research, there is a disconnect between the belief in the importance of genetic research and the willingness of individuals to participate themselves. This indicates a continued concern for the ways in which genetic materials are safeguarded once they are collected. Also indicated was a general lack of understanding about the various consent processes that go along with genetic research, which should be addressed further to ensure the successful continuation of biobanks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
