RESUMEN

Background: Research is needed to improve understanding of work-life integration issues in academic medicine and to guide the implementation of the Doris Duke Charitable Foundation's Fund to Retain Clinical Scientists (FRCS), a national initiative offering financial support to physician-scientists facing caregiving challenges. Materials and Methods: In 2018, as part of a prospective program evaluation, the authors conducted a qualitative study to examine FRCS program participants' initial impressions, solicit descriptions of their career and caregiving experiences, and inquire how such factors might influence their professional advancement. The authors invited all 33 awardees who had been granted FRCS funding in the first year of the program to participate in the study, of whom 28 agreed to complete an interview. Analysts evaluated de-identified transcripts and explicated the data using a thematic analysis approach. Results: While participants described aspects of a culture that harbor stigma against caregivers and impede satisfactory work-life integration, they also perceived an optimistic cultural shift taking place as a result of programs like the FRCS. Their comments indicated that the FRCS has the potential to influence culture if institutional leadership simultaneously fosters a community that validates individuals both as caregivers and as scientists. Conclusions: Insights garnered from this qualitative study suggest that there is a pressing need for institutional leaders to implement programs that can foster awareness and normalization of caregiving challenges. In addition to providing funding and other tangible resources, interventions should strive to reinforce a broader culture that affirms the presence of work-life integration challenges and openly embraces solutions.

RESUMEN

OBJECTIVES: To examine whether participants with the most behavioral goals to achieve were more likely to meet more goals than those given fewer goals. METHODS: Eight hundred ten participants were randomly assigned to advice-only, established guidelines for blood pressure control (reduced sodium, increased physical activity), or established guidelines plus the DASH diet (increased fruits, vegetables, low-fat dairy, reduced fat). RESULTS: At 6 months, 11.7% of Advice-Only, 19.3% of Established, and 44.6% of Established plus DASH met at least 3 goals (P<0.0001). At 18 months, 33.5% of Established plus DASH met at least 3 goals. CONCLUSIONS: Those with the most goals to achieve reached the most goals.

RESUMEN

PURPOSE: To enhance understanding of challenges related to work-life integration in academic medicine and to inform the ongoing implementation of an existing program and the development of other interventions to promote success of physician-scientists. METHOD: This study is part of a prospective analysis of the effects of the Fund to Retain Clinical Scientists (FRCS), a national program launched by the Doris Duke Charitable Foundation at 10 U.S. institutions, which provides financial support to physician-scientists facing caregiving challenges. In early 2018, 28 of 33 program awardees participated in semistructured interviews. Questions were about challenges faced by physician-scientists as caregivers and their early perceptions of the FRCS. Multiple analysts reviewed deidentified transcripts, iteratively revised the coding scheme, and interpreted the data using qualitative thematic analysis. RESULTS: Participants' rich descriptions illuminated 5 interconnected themes: (1) Time is a critical and limited resource, (2) timing is key, (3) limited time resources and timing conflicts may have a particularly adverse effect on women's careers, (4) flexible funds enable reclamation and repurposing of time resources, and (5) FRCS leaders should be cognizant of time and timing conflicts when developing program-related offerings. CONCLUSIONS: Programs such as the FRCS are instrumental in supporting individuals to delegate time-consuming tasks and to control how they spend their valuable time. Qualitative analysis suggests that access to and command of valuable time resources are crucial to career advancement, research productivity, and work-life flexibility, especially during critical time points along the physician-scientist trajectory.

RESUMEN

BACKGROUND: This study assessed the health needs and barriers to healthcare among women with a history of intimate partner violence (IPV) as told by women themselves. METHODS: Qualitative interviews were conducted with 25 women clients and 10 staff members at a crisis center in metropolitan North Carolina. Clients also completed a structured survey. RESULTS: Eleven shelter clients and 14 walk-ins completed the survey and interview. Client participants were demographically mixed, and 20% were Spanish-speaking immigrants. Most clients were unemployed and uninsured. Women reported worse health in the interviews than on the surveys; clients' major health needs were chronic pain, chronic diseases, and mental illness. Reported barriers to healthcare were cost, psychological control by the abuser, and low self-esteem and self-efficacy. Staff's perceptions of clients health needs differed from clients,' focusing on reproductive health, HIV/sexually transmitted infection (STI), mental illness, and inadequate preventive healthcare. Staff and clients' perceptions of barriers to healthcare were more congruent. Suggestions for improving the center's response were to offer more health education groups and more health-related staff trainings. Agency barriers to implementing these changes were limited funding, focus on crisis management, and perceived disconnect with the healthcare system. CONCLUSIONS: Health needs of women who have experienced IPV are significant and include physical and mental concerns. IPV creates unique barriers to accessing healthcare, which can be addressed only partially by a crisis center. Greater coordination with the healthcare system is needed to respond more appropriately to the health needs of women who have experienced IPV.

RESUMEN

Flaxseed is a rich source of lignan and has been shown to reduce androgen levels in men with prostate cancer. Polycystic ovarian syndrome (PCOS), a common endocrine disorder among women in their reproductive years, also is associated with high levels of androgens and is frequently accompanied by hirsutism, amenorrhea and obesity. This clinical case study describes the impact of flaxseed supplementation (30 g/day) on hormonal levels in a 31-year old woman with PCOS. During a four month period, the patient consumed 83% of the flaxseed dose. Heights, weights, and fasting blood samples taken at baseline and 4-month follow-up indicated the following values: BMI (36.0 vs. 35.7m/kg(2)); insulin (5.1 vs. 7.0 uIU/ml); total serum testosterone (150 ng/dl vs. 45 ng/dl); free serum testosterone (4.7 ng/dl vs. 0.5 ng/dl); and % free testosterone (3.1% vs. 1.1%). The patient also reported a decrease in hirsutism at the completion of the study period. The clinically-significant decrease in androgen levels with a concomitant reduction in hirsutism reported in this case study demonstrates a need for further research of flaxseed supplementation on hormonal levels and clinical symptoms of PCOS.

RESUMEN

PROBLEM: Junior faculty face challenges in establishing independent research careers. Declining funding combined with a shift to multidisciplinary, collaborative science necessitates new mentorship models and enhanced institutional support. APPROACH: Two multidisciplinary mentorship programs to promote grant success for junior faculty were established at the Duke University School of Medicine beginning in 2011. These four-month programs-the Path to Independence Program (PtIP) for National Institutes of Health (NIH) R applicants and the K Club for NIH K applicants-use multiple senior faculty mentors and professional grant-writing staff to provide a 20-hour joint curriculum comprising a series of lectures, hands-on workshops, career development counseling, peer groups, and an internal study section. In March 2016, the authors analyzed the success rate for all NIH grants submitted by participants since program enrollment. In a 2015 postprogram survey, participants rated their feelings of support and competency across six skill factors. OUTCOMES: From October 2011 to March 2016, the programs engaged 265 senior faculty mentors, 145 PtIP participants, and 138 K Club participants. Success rates for NIH grant applications were 28% (61 awards/220 decisions) for PtIP participants-an increase over the 2010 Duke University junior faculty baseline of 11%-and 64% (38/59) for K Club participants. Respondents reported significantly increased feelings of support and self-ratings for each competency post program. NEXT STEPS: The authors plan to expand the breadth of both the mentorship pool and faculty served. Broad implementation of similar programs elsewhere could bolster success, satisfaction, and retention of junior faculty investigators.

RESUMEN

CONTEXT: Nonalcoholic fatty liver disease and polycystic ovary syndrome (PCOS) are both associated with insulin resistance. Thus, women with PCOS may have an increased prevalence of nonalcoholic fatty liver disease, including nonalcoholic steatohepatitis (NASH). OBJECTIVE: The objective of the study was to determine the prevalence and characteristics of NASH and abnormal aminotransferase activity in women with PCOS. DESIGN: The study is a retrospective chart review. SETTING: The setting is an academic endocrinology clinic. PATIENTS: Patients were 200 women with PCOS, defined as irregular menses and hyperandrogenism. MAIN OUTCOME MEASURES: Biopsy-documented NASH and aminotransferase levels were the main outcome measures. RESULTS: Fifteen percent (29 of 200) had aspartate aminotransferase and/or alanine aminotransferase more than 60 U/liter. Women with aminotransferase elevations had lower high-density lipoprotein (HDL) (41 vs. 50 mg/dl, P = 0.006), higher triglycerides (174 vs. 129 mg/dl, P = 0.024), and higher fasting insulin (21 vs. 12 microIU/ml, P = 0.036) compared with women with normal aminotransferases. Six women (mean age 29 yr) with persistent aminotransferase elevations underwent liver biopsy. All six had NASH with fibrosis. Compared with the 194 of 200 PCOS women who did not undergo biopsy, women with biopsy-documented NASH had lower HDL (median 34 vs. 50 mg/dl, P < 0.001), and higher triglycerides (245 vs. 132 mg/dl, P = 0.025), fasting insulin (26 vs. 13 microIU/ml, P = 0.038), aspartate aminotransferase (144 vs. 22 U/liter, P < 0.001), and alanine aminotransferase (143 vs. 28 U/liter, P < 0.001). CONCLUSION: Abnormal aminotransferase activity is common in women with PCOS. Low HDL, high triglycerides, and high fasting insulin were associated with abnormal aminotransferase activity. Some women already had evidence of NASH with fibrosis. Further studies are needed to evaluate whether to screen PCOS women for liver disease at an earlier age than is currently recommended for the general population.

RESUMEN

BACKGROUND: In the United States, there is a high prevalence of metabolic syndrome, as defined by The Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (ATP III). The relationship between reproductive factors and metabolic syndrome in women is unknown. METHODS: We examined the association of number of children and breastfeeding history with metabolic syndrome risk among women. We used nationally representative data from the Third National Health and Nutrition Examination Survey (NHANES III). A total of 4699 (age > or = 20) nonpregnant women were included in this report. Metabolic syndrome was defined according to ATP III. RESULTS: Overall, 22.6% of women were determined to have metabolic syndrome. The rate of metabolic syndrome was significantly higher with increasing numbers of children, demonstrating a dose-response relationship (p < 0.0001). After controlling for age, race/ethnicity, income, education, and other sociodemographic, reproductive, and behavioral risk factors, the odds of metabolic syndrome increased 13% (95% CI, 6%-20%) with each additional child. In a similarly controlled analysis in parous women, the odds of metabolic syndrome decreased 22% (95% CI, 1%-39%) in women with a history of breastfeeding for >1 month. However, both effects were no longer significant after inclusion of body mass index (BMI) categories. CONCLUSIONS: In a national sample of women, increasing number of children was associated with higher rates of metabolic syndrome, and history of breastfeeding was associated with decreased rates of metabolic syndrome. The strength of these relationships was decreased after additional adjustment for BMI, suggesting that weight or weight changes may be an important mediator of the effects of parity and breastfeeding on the risk of metabolic syndrome.

RESUMEN

Differences and tensions between the Baby Boom generation (born 1945-1962) and Generation X (born 1963-1981) have profound implications for the future of academic medicine. By and large, department heads and senior faculty are Boomers; today's residents and junior faculty are Generation X'ers. Looking at these issues in terms of the generations involved offers insights into a number of faculty development challenges, including inadequate and inexpert mentoring, work-life conflicts, and low faculty morale. These insights suggest strategies for strengthening academic medicine's recruitment and retention of Generation X into faculty and leadership roles. These strategies include (1) improving career and academic advising by specific attention to mentoring "across differences"--for instance, broaching the subject of formative differences in background during the initial interaction; adopting a style that incorporates information-sharing with engagement in problem solving; offering frequent, frank feedback; and refraining from comparing today to the glories of yesterday; to support such improvements, medical schools should recognize and evaluate mentoring as a core academic responsibility; (2) retaining both valued women and men in academic careers by having departments add temporal flexibility and create and legitimize less-than-full-time appointments; and (3) providing trainees and junior faculty with ready access to educational sessions designed to turn their "intellectual capital" into "academic career capital."Given the trends discussed in this article, such supports and adaptations are indicated to assure that academic health centers maintain traditions of excellence.

RESUMEN

OBJECTIVE: To report a case of biopsy-documented nonalcoholic steatohepatitis (NASH), which improved appreciably through moderate exercise and weight loss in a young woman with polycystic ovary syndrome (PCOS) and insulin resistance. METHODS: We present a detailed case report, including laboratory and pathologic findings. In addition, we review the recent literature regarding the association of insulin resistance with NASH and PCOS. RESULTS: A 24-year-old woman was referred to the Duke Gastroenterology Clinic for evaluation of long-term high serum aminotransferase levels. She also reported a history of chronically irregular menses, infertility, and hirsutism and was diagnosed with PCOS. Subsequent glucose tolerance testing suggested the presence of insulin resistance. Liver biopsy findings were consistent with severe nonalcoholic steatohepatitis. Under the supervision of her physician and an exercise physiologist, the patient initiated a diet and exercise program that resulted in an 11.5% weight loss during approximately 8 months and yielded normalization of her aminotransferase levels. A repeat liver biopsy done 13 months after the initial biopsy revealed a substantial decrease in steatosis and a reduction in inflammation. CONCLUSION: Women with PCOS and insulin resistance have an increased risk of developing many of the consequences of the dysmetabolic syndrome, including type 2 diabetes, hypertension, and hyperlipidemia. This case report suggests that fatty liver and NASH may be other important diseases to identify in such women. It also demonstrates the improvement in this condition with moderate exercise and weight loss.

RESUMEN

BACKGROUND: The percentage of women graduating from U.S. medical schools has increased dramatically over the past 30 years, but the distribution of women and men across faculty ranks in academic medical centers has remained nearly unchanged. Women remain underrepresented in the senior ranks of academic medicine. The purpose of the study was to evaluate the work environment at Duke University Medical Center, with particular emphasis on gender climate. METHODS: An independent firm conducted structured focus groups and administered questionnaires, analyzed through conjoint analysis. Focus groups were stratified by rank and included the following groups of women: medical students, residents, fellows, junior faculty, senior faculty, and women in fields with few women. RESULTS: The conjoint analysis demonstrated that the women placed high value on the quality of their personal and work lives and rated these as more important than other traditional markers of career success, such as stature of their institution or earnings potential. Discussions during the focus groups elaborated on what "quality of personal and professional life" meant. They described a need for career efficiencies that allow individuals to excel professionally while also honoring their personal values and responsibilities. The discussions also suggested that similar problems have increasing importance for men. CONCLUSIONS: The results suggest that institutions should provide more alternative models of success and increase flexible work options. Future studies of women in academic medicine should explore the role of value conflict in career development in academic medicine and probe the idea that the priorities articulated by the women in these focus groups may reflect the values of a generation as much as they do gender.

RESUMEN

Polycystic ovary syndrome is now a well-recognized condition affecting 6%-25% of reproductive-aged women, depending on the definition. Over the past 3 decades, research has launched it from relative medical obscurity to a condition increasingly recognized as common in internal medicine practices. It affects multiple systems, and requires a comprehensive perspective on health care for effective treatment. Metabolic derangements and associated complications include insulin resistance and diabetes, hyperlipidemia, hypertension, fatty liver, metabolic syndrome, and sleep apnea. Reproductive complications include oligo-/amenorrhea, sub-fertility, endometrial hyperplasia, and cancer. Associated psychosocial concerns include depression and disordered eating. Additionally, cosmetic issues include hirsutism, androgenic alopecia, and acne. This review organizes this multi-system approach around the mnemonic "MY PCOS" and discusses evaluation and treatment options for the reproductive, cosmetic, and metabolic complications of this condition.

RESUMEN

Polycystic ovary syndrome (PCOS) is a chronic condition with many reproductive, metabolic and psychological manifestations. Insulin resistance puts women with PCOS at an increased risk for developing impaired glucose tolerance (IGT) and diabetes (T2D). An oral glucose tolerance test is the preferred IGT/T2D screening test, since it is most sensitive for detecting early glucose abnormalities. The goals in detecting IGT in these women are to avoid progression to T2D, modify cardiovascular risk and prevent gestational diabetes. Periodic IGT/T2D rescreening is necessary, given their propensity for more rapid deterioration in glucose tolerance. Lifestyle intervention is first-line therapy for PCOS women with IGT. Metformin is an option if lifestyle intervention fails to have an impact, while bariatric surgery is reserved for a select set of morbidly obese patients.

RESUMEN

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women. Women with PCOS frequently have metabolic complications including insulin resistance (IR), early diabetes, hypertension and dyslipidemia. Recent studies have demonstrated an association between PCOS and another metabolic complication: nonalcoholic fatty liver disease (NAFLD). NAFLD occurs as a result of abnormal lipid handling by the liver, which sensitizes the liver to injury and inflammation. It can progress to nonalcoholic steatohepatitis (NASH), which is characterized by hepatocyte injury and apoptosis. With time and further inflammation, NASH can progress to cirrhosis. Thus, given the young age at which NAFLD may occur in PCOS, these women may be at significant risk for progressive hepatic injury over the course of their lives. Many potential links between PCOS and NAFLD have been proposed, most notably IR and hyperandrogenemia. Further studies are needed to clarify the association between PCOS and NAFLD. In the interim, clinicians should be aware of this connection and consider screening for NAFLD in PCOS patients who have other metabolic risk factors. The optimal method of screening is unknown. However, measuring alanine aminotransferase and/or obtaining ultrasound on high-risk patients can be considered. First line treatment consists of lifestyle interventions and weight loss, with possible pharmacologic interventions in some cases.

RESUMEN

CONTEXT: Studies have demonstrated lipid differences among African-Americans and Caucasians and between women with polycystic ovary syndrome (PCOS) and normally ovulating women. However, few studies have examined racial differences in lipoprotein levels in women with PCOS. OBJECTIVE: This study compared lipoprotein levels in African-American and Caucasian women with PCOS. DESIGN AND SETTING: We performed a retrospective chart review of 398 subjects seen as new patients for PCOS at the Duke University Medical Center Endocrinology Clinic in Durham, NC. PATIENTS: We identified 126 charts appropriate for review, based on a diagnosis of PCOS (using the 1990 National Institutes of Health criteria), a self-reported race of either Caucasian or African-American, and a body mass index (BMI) higher than 25. We excluded patients taking glucophage, oral contraceptives, or lipid-lowering medications. MAIN OUTCOME MEASURE: Age, BMI, total cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, random triglycerides (TG), and oral glucose tolerance test measurements were collected and included in the analysis. RESULTS: African-American women with PCOS had higher HDL cholesterol levels (52.6 vs. 47.5 mg/dl, P = 0.019), lower non-HDL cholesterol (134.1 vs. 154.6 mg/dl, P = 0.046), and lower TG levels (97.5 vs. 168.2 mg/dl, P < 0.001) than Caucasian women. These differences could not be attributed to age, BMI, or differences in insulin resistance as determined by homeostasis model assessment of insulin resistance. CONCLUSION: African-American women with PCOS appear to have a more favorable lipid profile than Caucasian women with PCOS having higher HDL cholesterol, lower non-HDL cholesterol, and lower TG when BMI and insulin resistance are equal.

RESUMEN

PURPOSE: Women with polycystic ovary syndrome (PCOS) commonly have insulin resistance. Insulin resistance is associated with marked abnormalities of lipoprotein size and subclass particle concentration. The purpose of this study was to examine the effects of a moderate-intensity exercise program without weight loss on lipoprotein profiles in women with PCOS. METHODS: Thirty-seven sedentary PCOS women were randomized to either an 8- to 12-wk ramp-up followed by a 12-wk moderate-intensity exercise program (16-24 wk total, approximately 228 min x wk at 40-60% peak V x O2, n = 21) or control (no change in lifestyle, n = 16). PCOS was defined as or=8). Fasting lipoprotein profiles were obtained before and after the intervention. Nuclear magnetic resonance spectroscopy was used to quantify the following: average particle size, total and subclass concentrations of HDL, LDL, and VLDL particles, and calculated HDL cholesterol, triglycerides, and VLDL triglycerides. Wilcoxon exact rank sums tests were used to compare changes in these parameters in the exercise group relative to controls. RESULTS: Twenty women (8 exercisers, 12 controls) completed the study. Comparing exercisers to controls, significant changes were seen in concentrations of the following lipoprotein parameters that are associated with decreased insulin resistance: decreased large VLDL (P = 0.007), calculated triglycerides (P = 0.003), VLDL triglycerides (P = 0.003), and medium/small HDL (P = 0.031) and increased large HDL (P = 0.002) and average HDL size (P = 0.001). CONCLUSIONS: In this trial, moderate-intensity exercise without significant weight loss improved several components of the lipoprotein profiles of women with PCOS.
