Surgical Menopause and Estrogen Therapy Modulate the Gut Microbiota, Obesity Markers, and Spatial Memory in Rats.

Menopause in human females and subsequent ovarian hormone deficiency, particularly concerning 17ß-estradiol (E2), increase the risk for metabolic dysfunctions associated with obesity, diabetes type 2, cardiovascular diseases, and dementia. Several studies indicate that these disorders are also strongly associated with compositional changes in the intestinal microbiota; however, how E2 deficiency and hormone therapy affect the gut microbial community is not well understood. Using a rat model, we aimed to evaluate how ovariectomy (OVX) and subsequent E2 administration drive changes in metabolic health and the gut microbial community, as well as potential associations with learning and memory. Findings indicated that OVX-induced ovarian hormone deficiency and E2 treatment had significant impacts on several health-affecting parameters, including (a) the abundance of some intestinal bacterial taxa (e.g., Bifidobacteriaceae and Porphyromonadaceae), (b) the abundance of microbial short-chain fatty acids (SCFAs) (e.g., isobutyrate), (c) weight/BMI, and (d) high-demand spatial working memory following surgical menopause. Furthermore, exploratory correlations among intestinal bacteria abundance, cognition, and BMI underscored the putative influence of surgical menopause and E2 administration on gut-brain interactions. Collectively, this study showed that surgical menopause is associated with physiological and behavioral changes, and that E2-linked compositional changes in the intestinal microbiota might contribute to some of its related negative health consequences. Overall, this study provides novel insights into interactions among endocrine and gastrointestinal systems in the post-menopausal life stage that collectively alter the risk for the development and progression of cardiovascular, metabolic, and dementia-related diseases.

Speaker Introductions at Internal Medicine Grand Rounds: Forms of Address Reveal Gender Bias.

BACKGROUND: Gender bias has been identified as one of the drivers of gender disparity in academic medicine. Bias may be reinforced by gender subordinating language or differential use of formality in forms of address. Professional titles may influence the perceived expertise and authority of the referenced individual. The objective of this study is to examine how professional titles were used in the same and mixed-gender speaker introductions at Internal Medicine Grand Rounds (IMGR). METHODS: A retrospective observational study of video-archived speaker introductions at consecutive IMGR was conducted at two different locations (Arizona, Minnesota) of an academic medical center. Introducers and speakers at IMGR were physician and scientist peers holding MD, PhD, or MD/PhD degrees. The primary outcome was whether or not a speaker's professional title was used during the first form of address during speaker introductions at IMGR. As secondary outcomes, we evaluated whether or not the speakers professional title was used in any form of address during the introduction. RESULTS: Three hundred twenty-one forms of address were analyzed. Female introducers were more likely to use professional titles when introducing any speaker during the first form of address compared with male introducers (96.2% [102/106] vs. 65.6% [141/215]; p < 0.001). Female dyads utilized formal titles during the first form of address 97.8% (45/46) compared with male dyads who utilized a formal title 72.4% (110/152) of the time (p = 0.007). In mixed-gender dyads, where the introducer was female and speaker male, formal titles were used 95.0% (57/60) of the time. Male introducers of female speakers utilized professional titles 49.2% (31/63) of the time (p < 0.001). CONCLUSION: In this study, women introduced by men at IMGR were less likely to be addressed by professional title than were men introduced by men. Differential formality in speaker introductions may amplify isolation, marginalization, and professional discomfiture expressed by women faculty in academic medicine.

Neurological Disease in Women: Stroke, Cognition, and Headache.

In this clinical update, we selected recent publications relevant to common neurological concerns in women, with specific attention to stroke, cognition, and headache. We have chosen to highlight articles on sex differences in stroke and stroke treatment, the effect of hormone therapy on stroke risk and on cognition, and symptoms of the migraine postdrome.

Bioidentical hormone therapy: An assessment of provider knowledge.

OBJECTIVES: Bioidentical hormone therapy (BHT) is available in the United States in formulations that have been approved by the Food and Drug Administration (FDA) but also in formulations that have not been so approved. The aim of this study was to evaluate the knowledge, beliefs, and prescribing practices of BHT among healthcare providers. STUDY DESIGN: A cross-sectional self-selected responder survey was conducted of health care providers attending primary care Continuing Medical Education (CME) conferences in the United States from May 2012 to April 2013. The questionnaire consisted of 26 items assessing knowledge, beliefs, and current practice around BHT. RESULTS: A total of 366 survey responses were analyzed. Though 69.8% of respondents accurately identified the definition of BHT, only 45.3% were aware that BHT is available in FDA-approved products and 34.2% of respondents incorrectly identified that BHT is available only in custom-compounded formulations. Of those who had prescribed CC-BHT, less than half agreed with the statement "I am comfortable prescribing BHT" (45.4%). CONCLUSIONS: Our study showed that many practitioners are unaware that bioidentical hormones are available in FDA-approved products. Knowledge gaps identified by this survey highlight the need for and importance of education to further dispel misinformation surrounding the topic.

Care of Women During Menopause.

We would like to introduce a new section in the Journal of Women's Health, the Clinical Update. Important studies are continually published in both this Journal and other medical publications. However, it is difficult for busy providers to stay current with the changing literature. The Clinical Update is designed to serve as a review of recently published, high-impact, and potentially practice-changing journal articles, digested for our readers. The Clinical Update will be published on a quarterly basis. Each edition of the update will focus on a specific women's health topic, with planned topics to include menopause, sexual dysfunction, breast health, contraception, osteoporosis, and cardiovascular disease.

Reproductive Life Planning: A Cross-Sectional Study of What College Students Know and Believe.

Objectives The Centers for Disease Control and Prevention recommends a reproductive life plan (RLP) to promote individual responsibility for preconception health. The objectives of this study were to determine existing awareness of RLPs in a cohort of reproductive-age adults and to evaluate their knowledge level and beliefs about reproductive life planning. Methods We performed a cross-sectional survey study of adults ages 18-40 years old seeking care at the student health center of a large public university. Participation was voluntary. Survey responses were analyzed by age and gender. Results A total of 559 surveys were collected and analyzed. Only 24 % of participants had heard of an RLP although a majority (62.9 %) agreed that it is important to develop an RLP. Most respondents (85.4 %) preferred to receive information about reproductive life planning from a primary care provider or obstetrician-gynecologist, while only 4.2 % of patients surveyed reported ever being actually asked about an RLP by their healthcare provider. Among those who agreed that an RLP was important, knowledge of specific aspects of an RLP was lacking. Conclusions In our cohort of reproductive-age adults, general health literacy regarding RLPs was poor. Most of the young adults who responded to our survey did not know what an RLP was and even fewer had ever discussed one with their health provider.

Pregnancy and Parental Leave During Graduate Medical Education.

PURPOSE: To understand the pregnancy, childbirth, and parental leave plans and experiences of trainees in multiple graduate medical education (GME) programs at a single institution. METHOD: In 2013, the authors developed and deployed a voluntary, Internet-based survey of trainees in 269 residency and fellowship programs across the three sites of the Mayo School of Graduate Medical Education. The survey assessed pregnancy-related issues, including use of relevant institutional policies, changes in work due to pregnancy, and activities during pregnancy and parental leave. The authors analyzed the responses to make comparisons across groups. RESULTS: Forty-two percent (644/1,516) of trainees responded. Less than half (264; 41%) had children, and 46 (7%) were currently pregnant (themselves or their partners). Among parents, 24 (of 73; 33%) women and 28 (of 81; 35%) men planned to have another child during their current training program, and 13 (18%) women and 14 (17%) men planned to do so during their next training program. Among nonparents, 40 (of 135; 30%) women and 36 (of 111; 32%) men planned pregnancies during their current training program, and 25 (19%) women and 14 (13%) men planned pregnancies during their next training program. Of respondents eligible for parental leave, 81 (of 83; 98%) women and 89 (of 101; 88%) men had used it. CONCLUSIONS: Approximately 40% of respondents planned to have children during their GME training; most will require family leave and institutional support. GME programs should pursue policies and practices to minimize the effects of these leaves on their workforce.

Imploding and exploding migraine headaches: comparison of methods to diagnose pain directionality.

BACKGROUND: The study aims to compare methods of determining headache directionality (imploding, exploding, and/or ocular headaches) in women with migraine, investigate the concordance between physician assignment and patient self-assignment of pain directionality, and evaluate whether patients assigned their headaches to the same direction when queried using different methods. Directionality of migraine headache pain (imploding, exploding, or ocular) may reflect differences in the underlying pathogenesis of individual migraine attacks among and within individuals. Emerging evidence suggests that directionality of pain in migraine sufferers may predict response to onabotulinumtoxin A. The best method of determining headache directionality in migraine sufferers has not been systematically explored. METHODS: We conducted a prospective cross-sectional survey study of 198 female patients with migraine presenting to a Women's Health Clinic. Patients determined the directionality (imploding, exploding, and/or ocular) of their own migraine pain by choosing among 3 pictures graphically representing directionality and also by responding to a written question regarding directionality. Clinicians then classified directionality of migraine pain using structured interviews. Concordance between clinician assignment of directionality and patient self-assignment was determined with Kappa coefficients. RESULTS: Subjects were females between the ages of 18 and 77 years (mean 48 years). According to patient selection of representative pictures, 62 (31.6%) had imploding headaches with or without ocular pain, 36 (18.4%) had exploding headaches with or without ocular pain, 78 (39.8%) had ocular pain only, and 20 (10.2%) had imploding and exploding headaches with or without ocular pain. Two subjects did not respond. According to patient responses to a written question, 80 (41.0%) had imploding headaches with or without ocular pain, 53 (27.2%) had exploding headaches with or without ocular pain, 46 (23.6%) had ocular pain only, and 16 (8.2%) had imploding and exploding headaches with or without ocular pain. Three subjects did not respond. For physician assignment, 69 (34.9%) subjects had imploding headaches with or without ocular pain, 89 (45%) had exploding headaches with or without ocular pain, 14 (7.1%) had ocular pain only, and 26 (13.1%) had imploding and exploding headaches with or without ocular pain. The concordance (Kappa coefficient) between physician assignment of headache directionality with patient response to the written question was 0.33 (weak agreement), between physician assignment and patient assignment via selection of representative pictures was 0.35 (weak agreement), and between patient assignment via written question and via selection of representative pictures was 0.35 (weak agreement). CONCLUSIONS: The assignment of headache directionality varied substantially depending upon the method of determination. The concordance between clinician assignment, patient-self assignment via answering a written question, and patient self-assignment via choosing a representative picture was weak. Improved methods of determining pain directionality are needed.

Gender distribution of U.S. medical school faculty by academic track type.

PURPOSE: Over the past 30 years, the number and type of academic faculty tracks have increased, and researchers have found differences in promotion rates between track types. The authors studied the gender distribution of medical school faculty on the traditional tenure track (TTT) and clinician-educator track (CET) types. METHOD: The authors analyzed gender and academic track type distribution data from the March 31, 2011, snapshot of the Association of American Medical Colleges' Faculty Roster. Their final analysis included data from the 123 medical schools offering the TTT type and the 106 offering the CET type, which excluded any schools with 10 or fewer faculty on each track type. RESULTS: The original dataset included 134 medical schools representing 138,508 full-time faculty members, 50,376 (36%) of whom were women. Of the 134 medical schools, 128 reported at least one of four track types: TTT, CET, research track, and other. Of the 83 medical schools offering the CET type, 64 (77%) had a higher proportion of female than male faculty on that track type. Of the 102 medical schools offering the TTT type, only 20 (20%) had a higher proportion of female than male faculty on that track type. CONCLUSIONS: Medical schools offering the CET type reported higher proportions of female faculty on that track type. Given that faculty on the CET type lag behind their TTT colleagues in academic promotion, these findings may contribute to continued challenges in gaining academic and leadership parity for women in academic medicine.

Long-term follow-up of a facilitated peer mentoring program.

BACKGROUND: Mentoring plays an important role in career success of academic medical faculty. New mentoring models such as peer mentoring have emerged. AIM: To evaluate the long-term impact of a facilitated peer mentoring program on academic achievements. METHOD: Women faculty at the instructor or assistant professor rank were recruited to voluntarily participate in a facilitated peer mentoring program. Recruitment occurred over 3.8 years between 2005 and 2009. A 26-item questionnaire to assess academic skill, career satisfaction, and self-efficacy was administered before program participation and again with seven additional questions in 2011. Curriculum vitae were reviewed retrospectively to tally peer-reviewed publications, other academic activities, and promotions. RESULTS: Participants had long-term improvement in their perceived mastery of academic skills. Peer-reviewed publications, book chapters, abstracts, posters, and other academic activities increased when activities before the program were compared to those in the five years after program enrollment. At follow-up, participants reported positive perceptions of the program and 44% continued to work with their original peer mentor groups. CONCLUSIONS: Involvement in the facilitated peer mentoring program was associated with increased skills and academic activities for most participants. Future studies are needed to assess its applicability and success among various demographic groups in academic medicine.

Office-based management of fecal incontinence.

Fecal incontinence (FI) is a devastating disorder that is more prevalent than previously realized. FI is the involuntary loss of stool. Many factors contribute to the pathophysiology of FI, including advanced age, bowel irregularity, parity, and obesity. A detailed history and focused rectal examination are important to making the diagnosis and determining contributing causes. Although multiple diagnostic studies are available to assess the cause of FI, specific guidelines that delineate when testing should be done do not exist. Clinicians must weigh the risk, benefit, and burden of testing against the need for empiric treatment. All types of FI are initially managed in the same way, which includes lifestyle modification to reduce bowel derangements, improved access to toileting, and initiation of a bulking regimen to improve stool consistency. If initial conservative management fails, pharmaco-logic agents, biofeedback, or surgery may be indicated.
