RESUMO

PURPOSE: To perform a scoping review to determine what is known about emotional intelligence (EI) in undergraduate medical education (UME). Two main questions were asked: A. What medical student characteristics are associated with EI? Are there correlations with demographic or other factors? B. What research studies have been done on EI in UME? For example, is there evidence EI changes over time as a result of personal experiences? Should EI be used as an admission criterion? Can EI improve as a result of experiences or deliberate interventions? METHOD: The authors searched four databases (PubMed, PsycInfo, Education Resources Information Center, and Web of Science) for all papers published up to and including December 2020. Two reviewers independently screened articles to determine if they met inclusion criteria. All authors extracted and analyzed data. RESULTS: A set of 1520 papers on the topic of emotional intelligence was identified, with 119 papers meeting inclusion criteria. Most studies were done at international locations with only 17 done at US medical schools. Seventy-five were cohort or cross-sectional studies. Study populations were mixed among the studies, with year of medical study, inclusion of other healthcare students, and participation rates among the inter-study differences noted. CONCLUSIONS: Numerous gaps in the literature on EI exist with several points being clear: (1) there is disagreement on the definition of EI, (2) it is undetermined whether EI is a trait or an ability, and (3) there is marked variability among the instruments used to measure EI. It is also becoming apparent that using EI determination may be helpful as a component of the admission process, higher EI is likely related to improved clinical reasoning, and higher EI contributes to more effective stress management.

RESUMO

BACKGROUND: Multiple studies have suggested a relationship between adult exposures to environmental organochlorines and fecundability. There is a paucity of data, however, regarding fetal exposure to organochlorines via the mother's blood and fecundability of adult female offspring. METHODS: Data from a two-generation cohort of maternal fisheaters was investigated to assess female offspring fecundability. Serum concentrations of polychlorinated biphenyls (PCBs) and 1,1-bis-(4-chlorophenyl)-2,2-dichloroethene (DDE) in Michigan female anglers were serially measured between 1973 and 1991 and used to estimate in utero exposure in their female offspring using two different methods. The angler cohort included 391 women of whom 259 provided offspring information. Of 213 daughters aged 20-50, 151 participated (71 %) and provided information for time intervals of unprotected intercourse (TUI). The daughters reported 308 TUIs (repeated observations), of which 288 ended in pregnancy. We estimated the fecundability ratio (FR) for serum-PCB and serum-DDE adjusting for confounders and accounting for repeated measurements. An FR below one indicates a longer time to pregnancy. RESULTS: Compared to serum-PCB of <2.5 µg/L, the FR was 0.60 for serum-PCB between 2.5-7.4 µg/L [95 % confidence intervals (CI) 0.36, 0.99], and 0.42 [95 % CI 0.20, 0.88] for serum-PCB >7.4 µg/L. Similar results were obtained using the alternative statistical method to estimate in utero serum-PCB. The association was stronger for TUIs when women planned a baby; FR = 0.50 for serum-PCB between 2.5-7.4 µg/L, [95 % CI 0.29, 0.89], and 0.30 [95 % CI 0.13, 0.68] for serum-PCB >7.4 µg/L. There was no relationship between in utero exposure to DDE and fecundability in daughters. CONCLUSIONS: Decreased fecundability in female offspring of fisheaters was found to be associated with PCB exposure in utero, possibly related to endocrine disruption in the oocyte and/or other developing organs influencing reproductive capacity in adulthood.

RESUMO

BACKGROUND: Dichlorodiphenyl dichloroethylene (DDE) and polychlorinated biphenyls (PCBs) can be passed from mother to offspring through placental transfer or breastfeeding. Unknown is whether maternal levels can predict concentrations in adult offspring. OBJECTIVES: To test the association between maternal blood levels of DDE and PCBs and adult female offspring levels of these compounds using data from the Michigan Fisheaters'Cohort. METHODS: DDE and PCB concentrations were determined in 132 adult daughters from 84 mothers. Prenatal exposures were estimated based on maternal DDE and PCB serum levels measured between 1973 and 1991. Levels in adult daughters were regressed on maternal and estimated prenatal exposure levels, adjusting for potential confounders using linear mixed models. Confounders included daughter's age, birth order, birth weight, number of pregnancies, the length of time the daughter was breast-fed, the length of time the daughter breast-fed her own children, last year fish-eating status, body mass index, and lipid weight. RESULTS: The median age of the participants was 40.4 years (range 18.4-65.4, 5-95 percentiles 22.5-54.6%, respectively). Controlling for confounders and intra-familial associations, DDE and PCB concentrations in adult daughters were significantly positively associated with estimated prenatal levels and with maternal concentrations. The proportion of variance in the adult daughters' organochlorine concentrations explained by the maternal exposure levels is approximately 23% for DDE and 43% for PCBs. The equivalent of a median of 3.67 µg/L prenatal DDE and a median of 2.56 µg/L PCBs were 15.64 and 10.49 years of fish consumption, respectively. When controlling for effects of the shared environment (e.g., fish diet) by using a subsample of paternal levels measured during the same time frames (n=53 and n=37), we determined that the direct maternal transfer remains important. CONCLUSIONS: Estimated intra-uterine DDE and PCB levels predicted concentrations in adult female offspring 40 years later. Interpretation of adverse health effects from intra-uterine exposures of persistent pollutants may need to consider the sustained impact of maternal DDE and PCB levels found in their offspring.

RESUMO

OBJECTIVE: To determine whether prenatal exposure to dichlorodiphenyl ethylene (DDE) and polychlorinated biphenyls (PCBs) and concurrent exposure to DDE, PCBs and polybrominated diphenylethers (PBDEs) affect gene expression of aromatase (CYP19A1), 17-α-hydroxylase (CYP17A1), and oestrogen receptors α and ß (ESR 1 and ESR2). METHODS: Based on maternal PCB and DDE levels in the parent generation of the Michigan Fisheater Cohort determined between 1973 and 1991, individual prenatal exposures were estimated and have been published. In 2007, female adult offspring of this cohort were examined. Gene expression and concurrent lipid-adjusted exposures to DDE, PCBs and PBDEs were measured in blood and serum, respectively. Using mixed models and path analyses, gene-expression data were regressed on prenatal and concurrent exposures controlling for confounders. RESULTS: 139 daughters of Michigan fisheaters (65.3%) participated in the investigation. While prenatal PCB levels were statistically significantly associated with decreased expression of the aromatase and 17-α-hydroxylase genes, prenatal DDE levels were significantly related to increased gene expression of aromatase but not of 17-α-hydroxylase. The DDE association seems to be mediated by concurrent lipid-adjusted p,p'-DDE serum levels. Prenatal and concurrent exposure of both PCBs and DDE had comparable effects. No association was found for PBDEs or for the gene expression of ESR 1 and ESR2. CONCLUSIONS: A 40-year antecedent prenatal exposure and concurrent levels of PCBs and DDE are associated with the expression of aromatase and 17-α-hydroxylase genes. Prenatal exposures to organochlorines may instigate long-term alterations of gene expression. Mechanisms of prenatal induction of persistent gene-expression alterations are speculated to be epigenetic in nature.

RESUMO

Using grounded theory, a multidisciplinary study team compared the narratives of 30 women who had recently experienced a breast cancer scare. Even though 10 women received a benign diagnosis, all women reported a difficult time prediagnosis, characterized by an array of emotions and contemplation of the meaning of life. Diagnosis separated the two groups with emotional relief dominant for the benign group and intensification of emotions for the cancer group. For those diagnosed with cancer, three factors contributed to arriving at a point of acceptance about the diagnosis and treatment: (a) sustained coping mechanisms; (b) a belief system that shifted the meaning of the cancer experience; and (c) the ability to manage non-cancer-related stressful events. Implications include the need for tailored biopsychosocial treatments that focus on reducing stress, enhancing support systems, reframing beliefs about the illness, and providing the opportunity for the women to talk about their experiences.

RESUMO

Background: The physical, psychological, social, and spiritual quality of life (QoL) may be affected by breast cancer diagnosis and treatment, with mixed findings for psychological quality of life and cognitive ability performance. The present study aimed to evaluate QoL in women over 1 year from biopsy for a breast abnormality. Methods: Self-reported measures of physical, psychological, social, and spiritual QoL were obtained after biopsy results but prior to treatment initiation (baseline), 4 and 12 months later. CogState computerized neuropsychological screening battery also provided an evaluation of psychological QoL. Three groups of women including those with benign biopsy results, those with malignancy treated with chemotherapy, and those with malignancy not treated with chemotherapy were compared at 4 and 12 months after adjusting for baseline to isolate the effects of treatment. Additional covariates included are age, level of education, and income. Results: Benign biopsy results group included 72 women, whereas malignancy was found in 87 women of whom 33 were treated with chemotherapy and 54 without chemotherapy. At the time of diagnosis, women with cancer had worse psychological and social QoL but better spiritual QoL than those with benign biopsy results. Only CogState monitoring accuracy was worse for women with cancer compared with the controls at the time of biopsy results. After adjusting for QoL at baseline, women treated for cancer had worse physical and social QoL at 4 and 12 months later. Psychological well-being was worse for women with cancer at 4th month but improved at 1 year. No differences in cognition were found at 4 and 12 months when adjusted for baseline cognition and covariates. Discussion: Breast cancer is a traumatic life event for women, affecting psychological and social QoL domains, yet increasing spiritual QoL. Later, cancer treatment worsens physical, psychological, and social QoL compared with those without cancer. Conclusions: These findings suggest that interventions to improve psychological QoL may be especially important at the time of cancer diagnosis, while interventions to improve physical well-being are the most needed during and following cancer treatment. Support to improve social QoL is needed from the time of diagnosis into post-treatment survivorship.

RESUMO

BACKGROUND: It seems paradoxical that both increased height and earlier age at menarche (which predicts for shorter stature) are both associated with increased breast cancer risk. METHODS: Retrospective data from a parental cohort coupled with prospective interviews with and anthropometric measurements from their daughters were used. Multivariable linear regression analyses were conducted using mixed regression models to account for same-family participants. RESULTS: Controlling for birth weight, maternal height, and birth cohort, and analyzed as a group, a 1-year increase in the age at menarche predicted an increase in standing height, leg length, and trunk height of 0.76, 0.41, and 0.35 cm, respectively. However, when stratifying by birth year (prior to 1966 vs 1966 or after), these relationships were true only for those born prior to 1966. CONCLUSION: Given the height-breast cancer risk association, the emerging evidence linking breast cell proliferation to hormones associated with growth, and the finding in this study that the relationship between age at menarche and adult height no longer exists for women born in 1966 or later, it is possible that the long-established relationship between age at menarche and breast cancer risk may also no longer exist.

RESUMO

This article was migrated. The article was marked as recommended. In response to prevalent unprofessional behaviors during the 1990s, the medical school administration at Michigan State University's College of Human Medicine developed a student curriculum for professional development, called "The Virtuous Student Physician." However, as students adopted these professional aspirations and attributes, they noted that faculty members were not being held to the same standards. The medical school's senior associate dean for faculty affairs and development convened a task force to reframe professionalism for all faculty, residents, and students. Our first step was to survey our faculty regarding their awareness of the student professionalism curriculum and their own perceived professional weaknesses. This survey showed the following: most faculty members were aware of "The Virtuous Student Physician" curriculum, that faculty members identified social responsibility as the most difficult attribute to achieve, and that the most difficult behavior identified was working to resolve problem behaviors with colleagues. The task force then developed a new curriculum "The Virtuous Professional: A System of Professional Development for Students, Residents, and Faculty." The task force identified three core virtues (Courage, Humility, and Mercy) and reframed the professional attributes encompassed by these virtues to be aspirational for the entire learning community. The faculty of the College subsequently adopted the new principles and practices, including the use of routine, anonymous student evaluation of faculty professionalism. We are currently collecting data from student evaluations of their clinical faculty members. We plan to use this feedback to guide faculty development and recognize those who model exemplary professionalism as well as to address those who engage in unprofessional behavior.

RESUMO

The history of the acute respiratory distress syndrome (ARDS) parallels that of critical care. Descriptive and colorful names for the condition such as "shock lung," "post perfusion lung," and "traumatic wet lung" clearly communicate the reality that the pulmonary tissue is involved in a pathologic process. It is not difficult to speculate that the focus on the lung originated from the dramatic chest radiographs and gas exchange abnormalities frequently observed in association with the syndrome. However, a named condition does not necessarily dictate the therapeutic approach to it, and a review of some pertinent studies suggests the condition is in fact systemic in nature. Concurrent with this recognition, the need for markers of severity of illness has become more important. Rather than a process needing primarily pulmonary approaches to management, it now seems that ARDS is the result of systemic events with noticeable pulmonary manifestations, which may suffice as a clinical marker for severity of systemic inflammation. Because the pathophysiology has been described elsewhere, this article will focus on the clinical trials that are shaping our perception and management of the syndrome.

RESUMO

Hormonally-linked adult reproductive and anthropometric risk factors have been well established in the etiology of postmenopausal breast cancer, though early life exposures have been evaluated only more recently. Here, we examine the evidence for associations between lifetime reproductive and anthropometric risk factors for postmenopausal breast cancer. The review finds some evidence for the hypothesis that breast cancer risk is determined by the number of susceptible stem cells, modified by the hormonal environment. The in utero experience of an infant may be associated with postmenopausal breast cancer; preeclampsia may decrease and greater birthweight increase risk, but more evidence is needed. Earlier and more rapid childhood growth appears to increase postmenopausal breast cancer risk and childhood obesity to decrease risk, but very few studies have yet examined these associations. Increased final height and earlier age at menarche are consistently associated with increased risk for postmenopausal breast cancer. Later age at first birth, decreased parity, later menopausal age, use of hormone replacement therapy (especially progestin containing), and increased postmenopausal adiposity are well-established risk factors for postmenopausal breast cancer. The effect of a woman's own pregnancy conditions and lactation are not established. Further investigation is needed to identify whether events occurring early in life modify later events or accumulate over the life course. Many aspects of this research can be conducted by examining the influence of early life events on intermediary events without the need for longitudinal data.

RESUMO

Progesterone (P) regulates proliferation and differentiation in the normal mammary gland in mouse, rat and human. Progesterone has also been implicated in the etiology and pathogenesis of human breast cancer. The focus of this review is on recent advances in understanding the role of the progesterone receptor (PR) and functional significance of PR isoforms, PRA and PRB, in the normal mammary gland and in mammary cancer in mouse, rat and human.

RESUMO

PURPOSE: Many students in the Michigan State University College of Human Medicine (CHM) are non-traditional with unique needs and experiences. To meet these needs, in 1988 CHM developed a structured Extended Curriculum Program (ECP), which allows students to take longer than 2 years to complete the preclinical curriculum. This work examined the reasons why students extended their programs, their perceptions of that experience, and the outcome with respect to satisfaction and success in their careers after graduation. METHODS: The analysis used data from the college database, follow-up surveys of residency directors and graduates, surveys of graduates who extended, and the AMA Physician Masterfile. RESULTS: Graduates who responded to the survey were evenly split between those who extended for academic reasons and those who extended for other reasons. Although feelings about extending were mixed at the time of extension, nearly all respondents agreed that extending was the right decision in the long run. Extended students continued to face academic challenges having lower basic science averages, lower USMLE Step 1 and 2 first attempt pass rates, and more instances of repeated clerkships compared to those who did not extend, however, most were able to secure a residency in the specialty they desired and had comparable career satisfaction ratings. CONCLUSIONS: The ECP allows some students to complete medical school who otherwise may not have been able to do so. This analysis has provided valuable information that was used to improve the program, allowing CHM to continue its mission of training a diverse set of students to be exemplary physicians.

RESUMO

BACKGROUND AND OBJECTIVE: Given the large numbers of open breast biopsies performed in women who have benign breast masses, we developed a clinical decision rule (CDR), called BREASTAID, to triage women into open biopsy or follow-up. METHODS: A prospective cohort design was used to obtain data on 452 palpable breast masses evaluated at a referral clinic. Breast cancer was defined as ductal carcinoma in situ or invasive cancer at open biopsy. Separate logistic regression models were developed at three logical stages of the clinical workup. Bayes' theorem was applied in a stepwise fashion to revise model probabilities to generate a final probability of cancer. Receiver operator characteristics curves were generated to determine the optimum cut-point. Results derived from the CDR were compared with actual clinical practice. RESULTS: A total of 452 masses in 380 women were included. Clinical practice resulted in 180 masses (39.8%) undergoing open biopsy, 41 (22.8%) of which were cancers. Age, history of breast cancer in the mother, mass size, mammography findings, and fine needle aspiration biopsy results were included in the final models. When applied to the derivation dataset, BREASTAID successfully identified 40 of 41 cancer masses (sensitivity 97.6%, 95% confidence interval [CI] 94.1-99.9), and 350 of 411 noncancer masses (specificity 85.2%, 95% CI 81.8-88.5). BREASTAID would have reduced the number of biopsies performed on the 411 benign masses from 139 to 61. CONCLUSIONS: This study demonstrated that a CDR based on routinely collected clinical variables has the potential to accurately triage women with palpable breast masses. Further validation of the rule is required before its clinical use can be considered.

RESUMO

INTRODUCTION: We operationalized the taxonomy developed by Hauer and colleagues describing common clinical performance problems. Faculty raters pilot tested the resulting worksheet by observing recordings of problematic simulated clinical encounters involving third-year medical students. This approach provided a framework for structured feedback to guide learner improvement and curricular enhancement. METHODS: Eighty-two problematic clinical encounters from M3 students who failed their clinical competency examination were independently rated by paired clinical faculty members to identify common problems related to the medical interview, physical examination, and professionalism. RESULTS: Eleven out of 26 target performance problems were present in 25% or more encounters. Overall, 37% had unsatisfactory medical interviews, with 'inadequate history to rule out other diagnoses' most prevalent (60%). Seventy percent failed because of physical examination deficiencies, with missing elements (69%) and inadequate data gathering (69%) most common. One-third of the students did not introduce themselves to their patients. Among students failing based on standardized patient (SP) ratings, 93% also failed to demonstrate competency based on the faculty ratings. CONCLUSIONS: Our review form allowed clinical faculty to validate pass/fail decisions based on standardized patient ratings. Detailed information about performance problems contributes to learner feedback and curricular enhancement to guide remediation planning and faculty development.

RESUMO

The College of Human Medicine (CHM) at Michigan State University, which graduated its first class in 1972, was one of the first community-based medical schools in the country. It was established as a state-funded medical school with specific legislative directives to educate primary care physicians who would serve the needs of the state, particularly those of underserved areas. However, the model has proved challenging to sustain with the many changes to the health care system and the economic climate of Michigan. In 2006, a two-phase expansion plan was implemented, and in 2010, CHM permanently expanded the matriculating class from 106 to 200 students with the establishment of a second four-year site for medical education in Grand Rapids. This article describes what school leaders and faculty have learned as they look back at the opportunity provided by expansion as well as the growing pains and lessons learned. The community-based model met many of the mission-related goals for CHM's graduates, who represent a diverse group of practitioners whose values resonate with the school's mission. Expansion has offered an opportunity to explore new research and clinical opportunities as well as to more fully realize the potential of community partners to meet local health care needs and reinvent a robust future for community-integrated medical education.

RESUMO

BACKGROUND: Reliable techniques to measure polychlorinated biphenyl (PCB) congeners make the clearer definition of their effects on human health possible. Given that PCBs are classified as endocrine disrupters, we sought to explore the expression of some key genes involved in sex steroid metabolism. OBJECTIVES: To examine common classification schemes of PCB congeners and determine whether exposure to groups classified by mechanism of action alter the gene expression (GE) of CYP17, CYP19, and ESR1 and ESR2. METHODS: GE and exposure to various classifications of lipid-adjusted PCB congeners were examined in 139 daughters of the Michigan Fisheaters' Cohort. Using mixed models analyses and adjusting for age, menopausal status, and current use of oral contraceptives and hormone replacement therapy, GE data were regressed on exposure to PCB congener groupings based on mechanism of action. RESULTS: Three novel findings are elucidated: first, that up-regulation of CYP19 expression is associated with exposure to PCB groupings containing dioxin-like, potentially anti-estrogenic, immunotoxic congeners, including PCB IUPAC #74, #105, #118, #138, #156, #157, #158, #167, and #170 from this cohort. Second, that exposure to similar congeners (PCB IUPAC #105, #156, #157, #158, and #167 in this cohort) but using a classification based solely on hormonal mechanisms of action is associated with increased expression of ESR2. Third, that increased expression of CYP17 is of borderline significance when associated with exposure to PCB IUPAC #118, #138, and #156. CONCLUSIONS: These findings are both counter-intuitive and intriguing. Rather than exhibiting anti-estrogenic effects alone, they suggest that these congeners up-regulate the major enzyme involved in estrogen synthesis and tend to confirm previous findings of links between AhR and ER signaling pathways. Replication of these findings, expansion of the number of genes examined, exploration of mixtures of environmental chemicals, and subsequent study of health outcomes in a larger cohort are future priorities.

RESUMO

Breast cancer remained a hidden disease among women in the United States until the 20th century. It was initially brought into the open with public revelations from individual women, which was followed by the development of support groups and ultimately the formation of political activist groups with various priorities. Those concerned with toxic environmental exposures as a potential cause of breast cancer organized, demonstrated, and lobbied for research funding and eventually became partners in the research that arose from their efforts. One representative example was the Breast Cancer and Environment Research Centers (BCERC) Project (2003-2010), supported by the National Institute of Environmental Health Sciences (NIEHS) and the National Cancer Institute (NCI). The BCERC embedded a Community Outreach and Translational Core into its formal organizational infrastructure to ensure advocate involvement in the standing scientific subcommittees of BCERC, the first project funded by NIEHS and NCI to do so. The formal integration of advocates as partners in scientific studies focused on breast cancer is embedded in a rich history of action on the part of many courageous women. This article describes the historical evolution of breast cancer activism in the United States, which provided a critical foundation for the formation of BCERC. This description is followed by a discussion of BCERC as an example of the transdisciplinary research model, a paradigm that strives for inclusion of multiple stakeholders and increased interaction between scientists from a wide spectrum of disciplines, advocates, and lay audiences in order to more effectively conduct critical research and to translate and disseminate its findings.

RESUMO

OBJECTIVE: To examine the blood leukocyte expression of 22 sex steroid metabolic/signaling genes according to female reproductive status. METHODS: Michigan Fisheaters' Cohort participants underwent blood collection during the luteal phase of the menstrual cycle or randomly in non-menstruating participants. Gene expression (GE) was measured using Taqman hydrolysis probes and quantitative RT-PCR. Repeatability of four genes was determined in a subgroup. RESULTS: Five premenstrual, 57 premenopausal (20 users of systemic hormonal contraception), and 43 postmenopausal females participated. After Bonferroni correction for multiple comparisons of median GE between groups, three findings remained significant: greater GE of AhR in postmenopausal women than in premenopausal non-users of systemic hormonal contraception; and greater GE of ESR2 and HSD17B7 in premenstrual girls compared to postmenopausal women. Modest intra-class correlations were identified for CYP 19, ESR1, and ESR2 GE measured both in 2007 and 2010, but no intra-class correlation over the same time period was found for CYP17. CONCLUSIONS: There was little differential variation of blood leukocyte sex steroid ge between premenopausal women in the luteal phase of the menstrual cycle and postmenopausal women for most genes analyzed, but it will be necessary to make statistical adjustments in future epidemiologic studies in two circumstances: 1) when comparing AhR GE in premenopausal women non-users of systemic hormone contraception with postmenopausal women and 2) when comparing ESR2 and HSD17B7 GE in studies that include premenstrual girls. Developmental differences may explain the differential GE found in ESR2 and HSD17B7 in premenstrual girls compared with postmenopausal women.
