RESUMO

PURPOSE: Leadership development programs often use institutional projects to activate learning. We explored how project work shaped leadership identity formation in senior women leaders from one academic health science center who enrolled in The Hedwig von Ameringen Executive Leadership in Academic Medicine (ELAM®) program. MATERIALS AND METHODS: We interviewed ELAM Fellows and conducted a qualitative analysis of transcripts. Our primary analysis focused on the influences of projects on Fellows and institutions. Leadership identity formation emerged as a distinct pattern, so this narrative content was separated for secondary analysis. All authors approved the final assignment of themes and codes. RESULTS: Participants described a multi-dimensional process for developing a leadership identity. Themes encompassed participants' View of Self and One's Image as a Leader, Interpersonal Relationships, and Commitment to a Value-based Goal. These internal factors grounded external influences, such as interactions with colleagues and institutional leaders, and the world beyond the institution. CONCLUSIONS: We examined the process of leadership identity formation from the perspective of women leaders in academic health sciences who completed an institutional project during a leadership development program. Findings illustrate how internal and external forces, experienced in the context of project work, combine to influence leadership identity formation in women.

RESUMO

OBJECTIVE: Emerging research shows that women who sustain a mild traumatic brain injury, also termed concussion, have a higher risk of menstrual irregularities and sexual dysfunctions. However, no research exists on how these reproductive disruptions affect women's subsequent pregnancies. The objective of this study was to evaluate pregnancy outcomes after concussion in a cohort of reproductive-aged women (aged 18-45 years), 24 months post-injury. We hypothesized that, compared with their extremity-injured peers in the same cohort, women with concussion will have lower incidence of pregnancies. SETTING: Emergency department of a level 1 trauma center. PARTICIPANTS: Women of reproductive age (aged 18-45 years) seeking care for concussion or extremity injury. DESIGN: Longitudinal cohort study that used data collected at 3 distinct time points: t0, baseline: an original cohort of 245 women recruited in January to July 2017 for exposure assessment; t1, 6(+4) weeks post-injury: evaluation of self-reported postinjury menstrual and sexual changes for subgroup analyses-data collected in March to September 2017 ( n = 135); t2, 24 months post-injury: March 2020 chart review for documentation of pregnancies/pregnancy-related events ( N = 245). MAIN MEASURE: Poisson regression estimates used to model the incidence rate (IR) of pregnancies, comparing concussion with extremity injury. RESULTS: We reviewed the charts of 254 women from the t0 cohort. After excluding 9 patients who were either deceased or missing relevant data, we had the 245 (96.5%) charts of 102 concussed and 143 extremity-injured study participants. After adjusting for race and obstetric history, women with concussion had 80% lower incidence of pregnancies than their extremity-injured peers (adjusted [adj] IR = 0.20; 95% CI: 0.07-0.59; P = .003). When we excluded women who were using birth control, the IR of pregnancy for women with concussions was 76% lower than for those who had sustained extremity injuries (adj IR = 0.24; 95% CI: 0.07-0.81; P = .02). Pregnancy incidence remained consistently lower for concussed women in additional sensitivity analyses excluding assault/domestic violence victims and those with a prior/new concussion at t0 and t2. Subgroup analyses of the 135 women who had experienced menstrual and/or sexual dysfunctions at t1 showed 84% reduced incidence of pregnancy for women with concussions compared with those who had sustained an extremity injury (adj IR = 0.16; 95% CI: 0.04-0.73; P = .02). CONCLUSION AND RELEVANCE: Our study potentially serves as a clarion call to understand the long-term reproductive effects of female concussions.

RESUMO

INTRODUCTION: The Hedwig von Ameringen Executive Leadership in Academic Medicine program (ELAM) is a national professional development program for women that includes institutional action projects (IAPs). Although benefits of ELAM participation are well documented, the value of the IAPs has not been specifically evaluated. We explored the experience of ELAM Fellows and leaders from one institution to elucidate how institutional factors influence project implementation and outcomes. METHODS: Fellows and deans participated in semistructured interviews. We analyzed the transcripts qualitatively to develop themes and describe factors that influenced IAP implementation and outcomes. We used the New World Kirkpatrick Model, an updated version of the widely used Kirkpatrick model of educational program evaluation, as a framework to elucidate how participants applied their leadership learning through project work, and to analyze early results of projects that indicated institutional impact. RESULTS: Project work had bidirectional impact on the fellows in the program and on the institution itself. Project enablers included: focusing projects on institutional priorities, obtaining sustainable support, and navigating institutional complexity. Leading indicators of institutional outcomes included contributions to institutional leadership and culture, and mutual enhancement of the reputation of the fellow and of the institution. DISCUSSION: By examining enablers and barriers for institutionally based projects conducted in a national leadership development program, we identified the drivers that facilitated application of leadership learning. Leading indicators of project outcomes reflected bidirectional impact on fellows and the institution, demonstrating outcomes at the highest levels of the New World Kirkpatrick Model.

RESUMO

Objectives: Traumatic Brain Injury (TBI) has frequently been associated with changes in sexual functioning. The TBI and sexuality literature, however, has limited generalizability to concussed females, who often use the emergency department (ED) as their first line of care after head injury. Primary Objective: The primary objective of this study was to evaluate the impact of concussions on female sexual functioning. Secondary Objective: Secondarily, we evaluated if concussed women with sexual dysfunction also report more post-concussion symptoms (PCS) and/or mood changes. Research Design: This was a prospective cohort, with outcomes assessed at 6-10 weeks after ED enrollment. Methods and Procedures: Sexual dysfunction was defined as ≤ 45 on the Brain Injury Questionnaire on Sexuality (BIQS). The Rivermead Post-concussion Symptoms Questionnaire (RPQ) and the Hospital Anxiety and Depression Scale (HADS) assessed PCS and post-injury mood, respectively. Main Outcomes & Results: Eighty-nine eumenorrheic females (8-14 menstrual cycles/year) completed the study; 31(36%) had concussions, and 55(64%) were extremity injured. Concussed women had 70% increased risk of sexual dysfunction (adj.RR:1.70, 95% CI: 1.04,2.76; p = .03) versus extremity injured. Of clinical relevance, concussed women with sexual dysfunction also reported more PCS symptoms (adj.ß = 5.5, 95% CI: -6.7,18.2; p = .37) and mood scores (adj.ß = 8.0; 95% CI: -0.4, 16.4; p = .06). Conclusions: This study highlights the need for more research and interventions for one of the fastest growing subgroups within the TBI population.

RESUMO

Mentors rarely receive education about the unique needs of underrepresented scholars in the biomedical and behavioral sciences. We hypothesized that mentor-training and peer-mentoring interventions for these scholars would enrich the perceived quality and breadth of discussions between mentor-protégé dyads (i.e., mentor-protégé pairs). Our multicenter, randomized study of 150 underrepresented scholar-mentor dyads compared: 1) mentor training, 2) protégé peer mentoring, 3) combined mentor training and peer mentoring, and 4) a control condition (i.e., usual practice of mentoring). In this secondary analysis, the outcome variables were quality of dyad time and breadth of their discussions. Protégé participants were graduate students, fellows, and junior faculty in behavioral and biomedical research and healthcare. Dyads with mentor training were more likely than those without mentor training to have discussed teaching and work-life balance. Dyads with peer mentoring were more likely than those without peer mentoring to have discussed clinical care and career plans. The combined intervention dyads were more likely than controls to perceive that the quality of their time together was good/excellent. Our study supports the value of these mentoring interventions to enhance the breadth of dyad discussions and quality of time together, both important components of a good mentoring relationship.

RESUMO

PURPOSE: To conduct a randomized controlled trial to evaluate the effects of different mentoring interventions on the basic psychological need satisfaction of underrepresented minorities and women in academia. METHOD: Participants were 150 mentor/protégé dyads from three academic medical centers and eight other colleges and universities in western and central New York, randomized from 2010 to 2013 into mentor training (using principles of self-determination theory); peer mentoring for protégés; mentor training and peer mentoring for protégés combined; or control/usual practice. Protégé participants were graduate students, fellows, and junior faculty who were from underrepresented groups based on race, ethnicity, gender, or disability.The primary analysis was a comparison of intervention effects on changes in protégés' satisfaction of their basic psychological needs (competence, autonomy, and relatedness) with their mentor. They completed a well-validated, online questionnaire every two months for one year. RESULTS: There was no significant effect at the end of one year of either mentor training or peer mentoring on protégés' psychological basic need satisfaction with mentor specifically or at work in general. Exploratory analyses showed a significant effect of the mentor-based intervention on the protégés' overall psychological need satisfaction with their mentor at two months, the time point closest to completing mentor training. CONCLUSIONS: This randomized controlled trial showed a potential short-term effect of mentor training on changing basic psychological need satisfaction of underrepresented scholars with their mentors. Despite the lack of sustained effect of either mentor training or peer mentoring, these short-term changes suggest feasibility and potential for future study.

RESUMO

In this report, we describe a six-year experience (2007-2012) in a single CTSA awardee institution on the development, implementation and evaluation of a hybrid online mentoring curriculum that is applicable to CTSA trainees at various levels (graduate, medical students, and junior faculty) of career training. The curriculum offers convenience, engagement, and financial sustainability. Overall, we found high levels of satisfaction with the curriculum and mentoring experience among both protégés and mentors. Qualitative data showed remarkable consensus of 14 of the 15 domains of mentoring that form the framework of the mentoring curriculum: (1) accessibility, (2) selectivity, (3) engagement/support, (4) teaching/training, (5) clarity of performance/expectations, (6) sponsorship/sharing power judiciously, (7) demystifying the system (academia), (8) challenging/encouraging risk taking, (9) affirming, (10) providing exposure/visibility, (11) being an intentional role model, (12) protecting, (13) providing feedback, (14) self-disclosure, and lastly (15) counseling, with the fifteenth domain "counseling" being the most controversial. Quantitative survey data of both mentors and protégés indicated a high degree of overall satisfaction in their mentor-protégé dyad with 86% (59) of protégés and 86% (55) of mentors responding good or excellent to the "quality of time spent." Mentors and protégés were most satisfied in the area of research, with 93% (62) of protégés and 96% (57) of mentors finding discussions in research very to somewhat useful for their own career advancement. Along with wide acceptability, this format is a useful option for institutions where face-to-face time is limited and education budgets are lean.

RESUMO

We implemented the Duke Sickle Cell Disease (SCD) Transition Program for adolescents with SCD and investigated the knowledge about SCD; concerns and emotions about transitioning; and the initial impact of the Transition Program. Thirty-three adolescents participated in the initial study. Gaps in knowledge included ethnicities affected by SCD and inheritance of SCD. Adolescents were primarily concerned about transferring to a new medical team. There was a mix of both positive and negative emotions that varied over time. Overall, we have identified educational gaps and concerns and emotions about transitioning, which we will address through the Duke SCD Transition Program.

RESUMO

As part of an initiative to increase physician awareness about hypertension and cardiovascular disease (CVD); we studied the effects of a pilot intervention on the rates of referral for uncontrolled hypertension in an Ob-Gyn office. Physicians in an Ob-Gyn practice completed an educational session regarding hypertension and used a 1-page tracking form in their medical records for 3 months. Trained personnel reviewed medical records to compare baseline rates of hypertension control to those at the end of the intervention. Rates of counseling about lifestyle modification to control hypertension were also documented. The rate of referral for hypertension was significantly increased after 3 months (p<0.001). The rates of counseling about CVD risk factors approached 100%. In this study, hypertension was commonly under-treated, despite being a major risk factor for CVD. As primary care physicians, obstetrician-gynecologists are in an excellent position to facilitate evaluation and treatment of hypertension in women. Education about the importance of hypertension control along with a simple tracking form can assist Ob-Gyn physicians in complying with JNC 7 guidelines.

RESUMO

OBJECTIVE: There is currently a gap in treatment options for menopausal symptoms and a need for comprehensive therapies that are safe and effective for postmenopausal women. This review discusses challenges in the management of menopausal symptoms and the effect of the Women's Health Initiative (WHI) study findings on current treatment patterns. It also examines present and future therapies. RESEARCH DESIGN AND METHODS: A literature search was conducted using Medline, the Cochrane Database, and the National Heart Lung and Blood Institute WHI website with the following search terms: primary care, menopause, vasomotor symptoms, hormone therapy, osteoporosis, and vaginal atrophy. Searches were limited to articles published between 1995 and 2009. RESULTS: Comprehensive therapies that target several aspects of menopause, such as vasomotor symptoms and chronic disease prevention, are currently hormone based. These hormone-based approaches are considered more effective than currently available nonhormonal therapies for the relief of menopausal symptoms. However, hormone therapy is not recommended for women at high risk for venous thromboembolic events, cardiovascular disease, and/or breast cancer. A need exists for novel therapies that mitigate menopausal symptoms, provide protection from osteoporosis, and encourage patient compliance without promoting cancer, heart disease, or stroke. Emerging modalities and strategies, such as the tissue selective estrogen complex (TSEC), Org 50081, MF101, and desvenlafaxine, may provide improved options for postmenopausal women. CONCLUSIONS: Several new menopausal therapies that may help to address the ongoing unmet need for safe and effective therapies for postmenopausal women are currently in development. In particular, the TSEC, which provides the benefits of both a selective estrogen receptor modulator and conjugated estrogens with an improved tolerability profile, may offer advantages over currently available treatment options. Limitations of this review include the narrow search criteria and limited search period.

RESUMO

OBJECTIVE: To evaluate the effect of bazedoxifene/conjugated estrogens (BZA/CE), a tissue selective estrogen complex, on uterine bleeding in postmenopausal women. DESIGN: International, multicenter, randomized, double-blind, placebo- and active-controlled, phase III study (Selective estrogen Menopause And Response to Therapy [SMART]-1). SETTING: Outpatient clinical. PATIENT(S): Healthy, postmenopausal women (N = 3,397) aged 40 to 75 years with an intact uterus. INTERVENTION(S): Daily oral therapy with BZA 10, 20, or 40 mg, each with CE 0.625 or 0.45 mg, raloxifene 60 mg, or placebo. MAIN OUTCOME MEASURE(S): Cumulative amenorrhea profiles and the incidence of bleeding or spotting over 2 years. RESULT(S): Treatment with BZA 20 or 40 mg with CE 0.625 or 0.45 mg was associated with rates of cumulative amenorrhea (>83% during cycles 1-13 and >93% during cycles 10-13) and bleeding or spotting that were comparable to those with placebo. Subjects who received BZA 10 mg/CE 0.625 mg experienced slightly lower cumulative amenorrhea rates throughout the study compared with placebo-treated subjects. CONCLUSION(S): Postmenopausal women treated with BZA 20 or 40 mg with CE 0.625 or 0.45 mg had high rates of cumulative amenorrhea that were similar to those reported with placebo. This new menopausal therapy may offer a favorable bleeding and tolerability profile.

RESUMO

OBJECTIVE: To determine the integrity and copy number of mitochondrial DNA (mtDNA) in spermatozoa from infertile men. We also compared mtDNA integrity to nuclear DNA integrity. DESIGN: Observational. SETTING: Tertiary care center. PATIENT(S): Semen samples were collected from 57 men, whose wives were undergoing in vitro fertilization, including 24 men with normal semen parameters. MAIN OUTCOME MEASURE(S): Quantitative long polymerase chain reaction (PCR) and real-time PCR were used to measure mtDNA integrity and copy number in spermatozoa. We also measured nuclear DNA integrity of spermatozoa with flow cytometry after acridine orange staining. RESULT(S): A significant increase in mtDNA copy number and a decrease in mtDNA integrity were observed in the spermatozoa samples from patients with abnormal semen parameters compared to the patients with normal semen parameters. The integrity and copy number of mtDNA were significantly correlated with sperm count. CONCLUSION(S): Mitochondrial DNA quantity and quality may serve as useful diagnostic markers of sperm quality in infertile men.

RESUMO

BACKGROUND: Few studies have examined whether physician knowledge, attitudes, or practice patterns might contribute to gender disparities in the primary prevention of coronary heart disease (CHD), including among physicians caring for the largest number of reproductive-age women, obstetricians and gynecologists (OB/GYNs). We sought to identify barriers affecting the provision of recommended coronary risk factor therapies in women. METHODS: We surveyed internists and OB/GYNs who attended Grand Rounds presentations developed for the New York State Women and Heart Disease Physician Education Initiative. This program was designed to improve screening and management of coronary risk factors in women. Attendees were asked to complete a 7-minute questionnaire. RESULTS: The mean age of the 529 respondents was 40.3 years (standard deviation = 12.3), 75.1% were internists (n=378), and 42.7% (n=226) were women. Physicians correctly responded to 71.5% of the 13 questions assessing knowledge of coronary risk prevention (range, 4-13). Almost one third of internists and half of the OB/GYNs did not know that tobacco use was the leading cause of myocardial infarction in young women. For patients who smoked tobacco, only two thirds of internists and 55.4% of OB/GYNs reported suggesting a quit date (p=.007). After controlling for covariates, physicians who did not perceive time as a barrier were more likely to discuss smoking cessation (odds ratio=1.7 [1.1-2.7]). CONCLUSIONS: Among the internists and OB/GYNs surveyed, time was perceived as a barrier to implementing risk prevention. These physicians also underestimated the impact of tobacco use as a risk factor for CHD in young women. To lessen gender disparities in CHD prevention, both specialties need time-efficient educational programs that reflect specialty differences.

RESUMO

The location of semen collection (home vs. clinic) for IUI did not affect pregnancy rates in a general infertility population (633 IUI cycles from 335 patients), if World Health Organization guidelines for time from specimen collection to use were followed. The time interval from semen collection to IUI was not different between patients who conceived and those who did not (pregnant vs. nonpregnant, 70 +/- 19 minutes vs. 73 +/- 18 minutes).

RESUMO

Ascorbic acid has recently been reported to protect sperm DNA from the damage induced by exogenous oxidative stress in vitro. But, there is no report on seminal ascorbic acid and sperm DNA fragmentation in infertile men. In this study, we asked whether sperm DNA damage correlates with seminal ascorbic acid levels. Sperm DNA fragmentation index (DFI) was analysed in 75 men by flow cytometry after acridine orange staining. We also measured the levels of seminal plasma ascorbic acid and total antioxidant capacity. Abnormal sperm DNA integrity (DFI >or= 30%) was observed in 12% of the patients with normal semen parameters and in 52% of the patients with abnormal semen parameters. There were significant correlations between the level of DFI and conventional semen parameters including sperm count, motility and morphology (r = -0.29, -0.55 and -0.53 respectively; p < 0.05). Seminal ascorbic acid level was significantly lower in the patients with leucospermia than the patient with normal semen parameters. Interestingly, a significantly greater percentage of men with abnormal DFI were observed in the patients with low levels of seminal ascorbic acid compared with those with normal or high levels of ascorbic acid (59% vs. 33%, p < 0.05). Men with insufficient seminal ascorbic acid frequently have sperm DNA damage.

RESUMO

OBJECTIVE: To compare pregnancy rates with two different methods of intrauterine insemination (IUI) timing in patients treated with clomiphene citrate (CC). DESIGN: Prospective, randomized trial. SETTING: Academic medical center. PATIENT(S): One hundred fifty ovulatory, infertile women. INTERVENTION(S): Patients were randomized into a luteinizing hormone (LH) surge group or a follicle monitoring/human chorionic gonadotropin (hCG) group. All patients underwent baseline ultrasound, and took clomiphene citrate, during days 5-9. Patients in the LH surge group underwent IUI on the day after a home test for the LH surge was positive, whereas those in the hCG group received hCG according to ultrasound parameters and underwent insemination 33-40 hours later. Patients remained in the same study group for up to three cycles. MAIN OUTCOME MEASURE(S): Pregnancy rates per cycle and per patient. RESULT(S): No significant differences were found between groups in pregnancy rates per patient or per cycle. The LH surge group underwent IUI significantly later than the hCG group. Cancellation rates were significantly higher for the LH surge group (31% vs. 11%) and attributable mainly to failure to detect an LH surge. The majority of pregnancies in both treatment groups occurred in the first cycle. CONCLUSION(S): The decision to use hCG for IUI timing should be influenced by factors other than pregnancy rates.

RESUMO

Coronary heart disease (CHD) is a common and serious health problem facing women as they move beyond the reproductive years. Until recently, many postmenopausal women and their physicians relied heavily on hormone therapy to prevent cardiovascular disease, neglecting the well-recognized nonhormonal aspects of cardiovascular health. Simple lifestyle changes--exercise, diet, weight control, and avoidance of tobacco--can significantly reduce the chance of heart disease and its major risk factors, which are essentially the same for men and women. As with men, obesity, hypertension, hyperlipidemia, and diabetes are the major risk factors for heart disease in women.
