Abstract
PURPOSE Research has shown that barriers to career success in academic medicine disproportionately affect women. These barriers include inadequate mentoring, which may perpetuate the underrepresentation of women in senior leadership positions. The purpose of this review was to summarize the qualitative and quantitative evidence of the impact of mentoring on women's career outcomes and to inform future interventions to support the promotion and retention of women in academic medicine. METHOD The authors conducted a systematic review of original research published in English-language, peer-reviewed journals through March 20, 2020. Search terms related to mentorship, women, and academic medicine. The authors searched MEDLINE, Embase, Scopus, Current Contents Connect via Web of Science, Cochrane Library, and PsycINFO. They excluded studies not specifically addressing women and those without gender-stratified outcomes. They extracted and analyzed the following data: study design, population, sample size, response rate, participant age, percentage of women, mentoring prevalence, and outcomes. RESULTS Of 2,439 citations identified, 91 studies met the inclusion criteria, including 65 quantitative and 26 qualitative studies. Mentoring was associated with objective and subjective measures of career success. Women perceived mentorship to be more valuable to their career development yet were more likely to report having no mentor. Additionally, women were more likely to report lower levels of research productivity, less career satisfaction, and greater barriers to promotion. Qualitative results indicated that women had less access to informal mentoring and family responsibilities had a greater effect on their career outcomes. Professional networking, female mentors, and relational aspects of mentoring were common themes. CONCLUSIONS This review examined gender disparities in mentoring and the impact on research productivity, promotion success, and career satisfaction for women in academic medicine. Institution-supported mentoring programs are needed to facilitate identification of appropriate mentors and promotion of a more equitable academic career environment for women.

Expectations of and for Clerkship Directors 2.0: A Collaborative Statement from the Alliance for Clinical Education. TEACHING AND LEARNING IN MEDICINE 2021; 33:343-354. [PMID: 34294018 DOI: 10.1080/10401334.2021.1929997] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Accepted: 04/27/2021] [Indexed: 06/13/2023]
Abstract
This article presents an update of the collaborative statement on clerkship directors (CDs), first published in 2003, from the national undergraduate medical education organizations that comprise the Alliance for Clinical Education (ACE). The clerkship director remains an essential leader in the education of medical students on core clinical rotations, and the role of the CD has and continues to evolve. The selection of a CD should be an explicit contract between the CD, their department, and the medical school, with each party fulfilling their obligations to ensure the success of the students, the clerkship and of the CD. Educational innovations and accreditation requirements have evolved in the last two decades and therefore this article updates the 2003 standards for what is expected of a CD and provides guidelines for the resources and support to be provided.In their roles as CDs, medical student educators engage in several critical activities: administration, education/teaching, coaching, advising, and mentoring, faculty development, compliance with accreditation standards, and scholarly activity. This article describes (a) the work products that are the primary responsibility of the CD; (b) the qualifications for the CD; (c) the support structure, resources, and personnel that are necessary for the CD to accomplish their responsibilities; (d) incentives and career development for the CD; and (e) the dedicated time that should be provided for the clerkship and the CD to succeed. Given all that should rightfully be expected of a CD, a minimum of 50% of a full-time equivalent is recognized as appropriate. The complexity and needs of the clerkship now require that at least one full-time clerkship administrator (CA) be a part of the CD's team.To better reflect the current circumstances, ACE has updated its recommendations for institutions and departments to have clear standards for what is expected of the director of a clinical clerkship and have correspondingly clear guidelines as to what should be expected for CDs in the support they are provided. This work has been endorsed by each of the eight ACE member organizations.

Abstract
OBJECTIVE Determine and describe the impact of student/student mentoring (SSM) on the senior medical student mentor involved in a formal SSM program. METHOD An anonymous online survey was administered to fourth-year medical students at the University of North Carolina with questions regarding participation in SSM programs (formal and informal) as well as the impact of these experiences. Responses from fourth-year mentors were compared to non-mentors' answers. Data was analyzed to assess the value of, understand motivations for not participating in, and to describe perceptions regarding SSM. RESULTS One hundred seven of 178 students in the fourth-year class completed the survey, a 60% response rate. Forty-two students participated in the formal SSM program, 48 did not have mentors (non-mentors), and 17 were excluded as they participated in informal mentoring programs. There were no differences in gender, age, or matched specialty between mentors and non-mentors. Ninety-five percent of all students agreed that SSM was valuable in a way that was different from student/resident or student/faculty mentoring. Mentors were nearly twice as non-mentors likely to believe that being the mentee in an SSM relationship would be beneficial. In addition, mentors were 4 times more likely to believe that being a mentor in an SSM program was valuable and 83% stated they would mentor again. Lastly, nearly three quarters of mentors felt that this was a worthwhile experience. CONCLUSIONS Students who served as mentors as part of an SSM program had positive experiences and found it a valuable addition to traditional faculty/student mentoring.

Abstract
OBJECTIVE There is a critical shortage of child and adolescent psychiatrists in the United States. Increased exposure, through mentorship, clinical experiences, and research opportunities, may increase the number of medical students selecting child and adolescent psychiatry (CAP) as a career choice. METHOD Between 2008 and 2011, 241 first-year participants of a program to increase exposure to CAP, funded by the Klingenstein Third-Generation Foundation (KTGF) at 10 medical schools completed baseline surveys assessing their opinions of and experiences in CAP, and 115 second-year participants completed follow-up surveys to reflect 1 year of experience in the KTGF Program. RESULTS Students reported significantly increased positive perception of mentorship for career and research guidance, along with perceived increased knowledge and understanding of CAP. CONCLUSIONS Results suggest that the KTGF Program positively influenced participating medical students, although future studies are needed to determine whether these changes will translate into more medical students entering the field of CAP.

Abstract
OBJECTIVE Maternal major depressive disorder is an established risk factor for child psychopathology. The authors previously reported that 1 year after initiation of treatment for maternal depression, children of mothers whose depression remitted had significantly improved functioning and psychiatric symptoms. This study extends these findings by examining changes in psychiatric symptoms, behavioral problems, and functioning among children of depressed mothers during the first year after the mothers' remission from depression. METHOD Children were assessed at baseline and at 3-month intervals with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, the Child Behavior Checklist, and the Children's Global Assessment Scale for 1 year after their mothers' remission or for 2 years if the mothers did not remit. The authors compared children of early remitters (0-3 months; N=36), late remitters (3-12 months; N=28), and nonremitters (N=16). RESULTS During the postremission year, children of early-remitting mothers showed significant improvement on all outcomes. Externalizing behavioral problems decreased in children of early- and late-remitting mothers but increased in children of nonremitting mothers. Psychiatric symptoms decreased significantly only in children of mothers who remitted, and functioning improved only in children of early-remitting mothers. CONCLUSIONS Remission of mothers' depression, regardless of its timing, appears to be related to decreases in problem behaviors and symptoms in their children over the year after remission. The favorable effect of mothers' remission on children's functioning was observed only in children of early-remitting mothers.

Abstract
Inpatient child and adolescent psychiatry leadership roles are often multifaceted, necessitating strong clinical knowledge and skills, organizational and leadership abilities, and in the academic setting the desire and skill in teaching and research. Early career psychiatrists who do possess these attributes may find themselves unprepared for such challenges as dealing with complex administrative and economic issues, accreditation, legal matters, and multitasking. This article offers a primer addressing these basic issues and in managing change through quality improvement processes.

Abstract
Family functioning and parenting were hypothesized to mediate the relation between remission of maternal depression and children's psychosocial adjustment. Participants were 114 mother-child dyads participating in the Sequenced Treatment Alternatives to Relieve Depression Child 3-month follow-up. All mothers had been diagnosed with major depressive disorder and were treated initially with citalopram; 33% of mothers experienced remission of depressive symptoms. Youth ranged in age from 7 to 17. Remission of maternal depression was associated with changes in children's reports of their mothers' warmth/acceptance, which in turn partially mediated the relation between maternal depression remission and youth internalizing symptoms, accounting for 22.9% of the variance.

Abstract
OBJECTIVE Maternal depression is a consistent and well-replicated risk factor for child psychopathology. The authors examined the changes in psychiatric symptoms and global functioning in children of depressed women 1 year following the initiation of treatment for maternal major depressive disorder. METHOD Participants were 1) 151 women with maternal major depression who were enrolled in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study and 2) their eligible offspring who, along with the mother, participated in the child STAR*D (STAR*D-Child) study (mother-child pairs: N=151). The STAR*D study was a multisite study designed to determine the comparative effectiveness and acceptability of various treatment options for adult outpatients with nonpsychotic major depressive disorder. The STAR*D-Child study examined children of depressed women at baseline and involved periodic follow-ups for 1 year after the initiation of treatment for maternal major depressive disorder to ascertain the following data: 1) whether changes in children's psychiatric symptoms were associated with changes in the severity of maternal depression and 2) whether outcomes differed among the offspring of women who did and did not remit (mother-child pairs with follow-up data: N=123). Children's psychiatric symptoms in the STAR*D-Child study were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), and maternal depression severity in the STAR*D study was assessed by an independent clinician, using the 17-item Hamilton Depression Rating Scale (HAM-D). RESULTS During the year following the initiation of treatment, maternal depression severity and children's psychiatric symptoms continued to decrease over time. Decreases in the number of children's psychiatric symptoms were significantly associated with decreases in maternal depression severity. When children's outcomes were examined separately, a statistically significant decrease in symptoms was evident in the offspring of women who remitted early (i.e., within the first 3 months after the initiation of treatment for maternal depression) or late (i.e., over the 1-year follow-up interval) but not in the offspring of nonremitting women. CONCLUSIONS Continued efforts to treat maternal depression until remission is achieved are associated with decreased psychiatric symptoms and improved functioning in the offspring.

Abstract
OBJECTIVE The authors aimed to determine whether a structured clinical experience in child and adolescent psychiatry (CAP) during the third-year psychiatry clerkship would impact interest in pursuing careers in psychiatry and CAP. METHODS The authors constructed and administered a postrotation survey, the Child and Adolescent Psychiatry Experiences Questionnaire (CAPE-Q), to evaluate clinical experiences and career interest in psychiatry and CAP both before and after a clerkship in psychiatry. The value of specific aspects of the clerkship to students' career decisions was also assessed. The students completed the surveys at the end of their psychiatry clerkship in the 2005-2006 academic year and in their first rotation of 2006-2007. RESULTS Of the 98 respondents, the majority reported no change in interest in general psychiatry or in CAP after the clerkship. However, exposure to inpatient CAP correlated with increased interest in the field and in its influence on pursuing a CAP career. Interest in CAP positively correlated with agreement that the CAP clinical experience influenced their career decision. The influence of the CAP clinical experience on career decision was associated with interest in both psychiatry and CAP, as well as with change in CAP interest after the clerkship. CONCLUSION These preliminary results suggest that the CAPE-Q may be useful for assessing students' clerkship experiences and the impact of these experiences on their decision to pursue a career in child psychiatry. Here, inpatient CAP experience led to increased interest in the field. The CAPE-Q could be used to identify students for whom electives and mentoring opportunities could be arranged. It could also be used in assessment of clerkship experiences.

Abstract
CONTEXT Children of depressed parents have high rates of anxiety, disruptive, and depressive disorders that begin early, often continue into adulthood, and are impairing. OBJECTIVE To determine whether effective treatment with medication of women with major depression is associated with reduction of symptoms and diagnoses in their children. DESIGN Assessments of children whose depressed mothers were being treated with medication as part of the multicenter Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial conducted (between December 16, 2001 and April 24, 2004) in broadly representative primary and psychiatric outpatient practices. Children were assessed by a team of evaluators not involved in maternal treatment and unaware of maternal outcomes. Study is ongoing with cases followed at 3-month intervals. SETTING AND PATIENTS One hundred fifty-one mother-child pairs in 8 primary care and 11 psychiatric outpatient clinics across 7 regional centers in the United States. Children were aged 7 to 17 years. MAIN OUTCOME MEASURES Child diagnoses based on the Kiddie Schedule for Affective Disorders and Schizophrenia; child symptoms based on the Child Behavior Checklist; child functioning based on the Child Global Assessment Scale in mothers whose depression with treatment remitted with a score of 7 or lower or whose depression did not remit with a score higher than 7 on the Hamilton Rating Scale for Depression. RESULTS Remission of maternal depression after 3 months of medication treatment was significantly associated with reductions in the children's diagnoses and symptoms. There was an overall 11% decrease in rates of diagnoses in children of mothers whose depression remitted compared with an approximate 8% increase in rates of diagnoses in children of mothers whose depression did not. This rate difference remained statistically significant after controlling for the child's age and sex, and possible confounding factors (P = .01). Of the children with a diagnosis at baseline, remission was reported in 33% of those whose mothers' depression remitted compared with only a 12% remission rate among children of mothers whose depression did not remit. All children of mothers whose depression remitted after treatment and who themselves had no baseline diagnosis for depression remained free of psychiatric diagnoses at 3 months, whereas 17% of the children whose mothers remained depressed acquired a diagnosis. Findings were similar using child symptoms as an outcome. Greater level of maternal response was associated with fewer current diagnoses and symptoms in the children, and a maternal response of at least 50% was required to detect an improvement in the child. CONCLUSIONS Remission of maternal depression has a positive effect on both mothers and their children, whereas mothers who remain depressed may increase the rates of their children's disorders. These findings support the importance of vigorous treatment for depressed mothers in primary care or psychiatric clinics and suggest the utility of evaluating the children, especially children whose mothers continue to be depressed.

Abstract
OBJECTIVE To assess the current and lifetime prevalence of psychiatric disorders among children of currently depressed mothers and to assess the association of clinical features of maternal depression (i.e., severity, chronicity, and clinical features) with child psychopathology. Mothers were participants in the STAR*D (Sequenced Treatment Alternatives to Relieve Depression) multisite trial, designed to compare effectiveness and acceptability of different treatment options for outpatients with non-psychotic major depressive disorder (MDD). METHOD Treatment-seeking mothers with a current DSM-IV diagnosis of MDD and with at least 1 child 7 to 17 years old were assessed during a major depressive episode (MDE). For each mother, 1 child was assessed (if a mother had more than 1 child, 1 was randomly selected). Maternal features assessed for this study were history of MDEs, severity of current MDE, comorbid conditions, depressive symptom features, and social functioning. Children were assessed for selected psychiatric diagnoses (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version [K-SADS-PL]), psychopathologic symptoms and social functioning (Child Behavior Checklist), and global functioning (Children's Global Assessment Scale). Data were gathered from December 2001 to April 2004. RESULTS A large proportion (72%) of mothers were severely depressed (17-item Hamilton Rating Scale for Depression score >/= 22). About a third (34%) of children had a current psychiatric disorder, including disruptive behavior (22%), anxiety (16%), and depressive (10%) disorders. Nearly half (45%) had a lifetime psychiatric disorder, including disruptive behavior (29%), anxiety (20%), and depressive (19%) disorders. Atypical depressive features in the mother were associated with a 3-fold increase in the odds of having a child with depressive (OR = 3.3 [95% CI = 1.2 to 9.5]; p = .02) or anxiety (OR = 2.6 [95% CI = 1.1 to 6.9]; p = .03) disorders. A history of maternal suicide attempts and the presence of comorbid panic disorder with agoraphobia were associated with a 3-fold increase and an 8-fold increase in the odds of depressive disorders in the offspring, respectively. The final model showed significant associations (p </= .05) between the following characteristics of maternal depression and offspring disorders: maternal comorbid panic disorder with agoraphobia and offspring depressive and anxiety disorders, maternal irritable depression and offspring disruptive behavior disorders and any disorder, and maternal substance use disorders and any disorder. CONCLUSIONS Children of mothers in the midst of a current MDE are at high risk for disruptive behavior and anxiety disorders. The elevated risk of psychopathology among children of depressed mothers may recommend assessment of these children when clinically suggested. Children of depressed mothers with comorbid panic disorder with agoraphobia are at high risk for depressive and anxiety disorders and deserve special attention from clinicians.

Abstract
The limited communication skills and varying behavior patterns of people with mental retardation make the diagnosis of psychiatric disorders a challenging task. The authors present the case of a patient with mild mental retardation and possible panic disorder whose panic symptoms were missed by clinicians until a structured questionnaire to screen for those symptoms was administered. In assessing people with mental retardation for psychiatric disorder, clinicians should be alert to the possibility of panic disorder if patients show avoidant behaviors and report vague somatic complaints. A simplified structured format for assessment may lead to more accurate diagnosis.

Abstract
Sterile perforated polyethylene spheres (wiffle golf balls) were implanted s.c. in beagle dogs. A local inflammatory reaction was elicited within the spheres by injecting carrageenan. Changes in leukocyte count, prostaglandin E2, thromboxane B2 and leukotriene B4 levels were monitored in fluid samples collected over a 24-hr period. Blood samples were also collected at various time points and analyzed for prostaglandin E2 and leukotriene B4 production after ex vivo calcium ionophore treatment. Effects of standard antiinflammatory agents (aspirin, indomethacin, dexamethasone, tenidap and zileuton) and newer cyclooxygenase-2 (COX-2) selective agents (nimesulide, nabumetone and SC-58125) were determined after oral administration. Ex vivo inhibition of cyclooxygenase product synthesis (prostaglandin E2, thromboxane B2) in whole blood was used as an indicator of activity for the constitutive COX-1 isoform, although inhibition of the synthesis of these mediators in the chamber exudate during an inflammatory process is believed to represent COX-2 inhibition. Treatment effects on leukotriene B4 production were also determined both ex vivo in whole blood and in the fluid. All of the compounds tested, except aspirin, inhibited leukocyte infiltration into the fluid exudate. Inhibitors that exert their effects on both isozymes of cyclooxygenase attenuate production of cyclooxygenase metabolites in both the inflammatory exudate and in peripheral blood ex vivo, although COX-2 selective inhibitors only demonstrated activity in the exudate. A 5-lipoxygenase inhibitor (zileuton), a corticosteroid (dexamethasone) and a dual COX-2 selective/5-lipoxygenase inhibitor (RWJ 63556) had similar profiles in that they all inhibited cell infiltration and eicosanoid production in the fluid and also attenuated leukotriene B4 production in both the fluid and blood.

Abstract
Further investigation of the structural requirements of a series of benzylphosphonic acid inhibitors of human prostatic acid phosphatase has led to the highly potent series of alpha-aminobenzylphosphonic acids. The alpha-benzylaminobenzylphosphonic acid, with an IC50 = 4 nM, exhibited a 3500-fold improvement in potency over the carbon analogue, alpha-phenylethyl. The enhanced potency may be due to a combination of four favorable interactions including those with the phosphate binding region, the presence the hydrophobic moieties of the benzylamino and phenylphosphonic acid, and a rigid conformer produced by an internal salt bridge between the phosphonate and the alpha-amino group. Replacement of the phosphonic acid moiety with a phosphinic or carboxylic acid as well as deletion of the benzyl substitution of the alpha-amino group led to great reductions in potency.

Abstract
We recently reported on a series of pyrrole Mannich bases orally active in inhibiting the conditioned avoidance response (CAR) in rats. These compounds exhibit affinity for both D2 and 5-HT1A receptors, and some are noncataleptogenic. Such a profile suggests that they may be potential antipsychotic agents which lack the propensity for causing extrapyramidal side effects and tardive dyskinesias in humans. One of these compounds, 1-[[1-methyl-5-[[4-[2-(1-methylethoxy)phenyl]- 1-piperazinyl]methyl]-1H-pyrrol-2-yl]methyl]-2-piperidinone (RWJ 25730, 1), was chosen for further development but found to be unstable in dilute acid. In order to improve stability, we replaced the pyrrole methylene linkage to the piperazine ring with ethylene, employed ethylene and dicarbonyl as linkers between the lactam and the pyrrole ring, placed electron-withdrawing groups on the pyrrole ring, and substituted acyclic amide for lactam. In addition, we replaced the pyrrole segment with other heterocycles including thiophene, furan, isoxazole, isoxazoline, and pyridine. Generally, replacement of the N-methylpyrrole segment with thiophene, furan, isoxazoline, or pyridine afforded compounds equipotent with 1 in CAR, which were more stable in dilute acid. In the case of side chain or lactam modifications, CAR activity was significantly decreased or abolished, with the exception of 6. For the most part, the modifications to 1 resulted in the decrease or loss of D2 receptor binding. However, within this series, 5-HT1A receptor binding was greatly increased, with thiophene 40 exhibiting an IC50 of 0.07 nM. The CAR activities of pyrroles 6 and 12, thiophene 40, furans 44-47, isoxazolines 49 and 50, and pyridine 54 coupled with their weak or nonexistent D2 binding and strong 5-HT1A binding suggest that they may be acting via a nondopaminergic mechanism or that dopaminergic active metabolites are responsible. Pyrrole 6 and furans 44 and 47 show promise as antipsychotic agents based on their CAR activity, receptor-binding profile, and solution stability.

Abstract
The subject of symptom recognition in infants is just beginning to be explored in nursing literature; the process may be more difficult that it originally appears. Because symptoms are subjective and their identification is dependent on communication between the client and the nurse or caretaker, it becomes important to assist nurses, parents, and other health care providers in this process. This article discusses the impact of cues, developmental aspects, and inferences as they influence the identification of symptoms experienced by infants.

Within 1 week of subcutaneous implantation of tumor the leukocyte count began to increase and reached average levels of 165,000 leukocytes per cubic millimeter within 18 days. This represented an increase in mature neutrophils primarily, although other blood leukocytes were modestly increased as well. The total number of neutrophils per humerus was increased but no increase was detected in the number of myloblasts, promyelocytes, or myelocytes. The tritiated thymidine-labeling index of the latter three cells was not significantly changed during tumor growth. The number of progenitor cells forming granulocytic and mononuclear cells in vitro was decreased in the marrow during tumor growth. Colony-stimulating activity in plasma was slightly increased during the early phase of tumor growth and decreased during later phases. Emergence time of blood neutrophils was normal, as measured by labeling with tritiated thymidine, but decline in labeled cells was abnormally slow in tumor-bearing mice. There was a shift of erythropoiesis to the spleen, but total erythropoiesis appeared to be normal in most mice. Surgical excision of the tumor resulted in prompt reversal of the leukemoid reaction. In the aggregate these results are consistent with a hypothesis that the leukemoid reaction was the result of increased blood transit time of neutrophils primarily, rather than increased neutrophil production.
