RESUMO

"Lifestyle medicine (LM) is an evidence-based therapeutic intervention delivered by clinicians trained and certified in this specialty to prevent, treat, and often reverse chronic disease". Eighty percent of the conditions primary care physicians routinely encounter in their offices, e.g., diabetes mellitus, hypertension, COPD, cardiovascular disease, have root causes in poor lifestyle choices, e.g., smoking, insufficient sleep, being sedentary, eating highly processed foods. Lifestyle is the foundation of most chronic disease management guidelines aimed at reducing morbidity and mortality. Studies have shown that changes in lifestyle can be achieved and the changes link almost directly to reduction in risk for chronic illness. Primary care physicians are ideally positioned to incorporate LM into their practices. It is important to recognize and find solutions to the many barriers to implementing LM from the patient, physician, and system level. There is an urgent need to increase opportunities for practicing physicians to increase their knowledge and skills related to LM and include this in medical school and residency curricula. Many resources exist that can provide the necessary training to seasoned physicians and students/residents to become competent in practicing LM and address barriers to implementing LM. LM has the potential to revolutionize clinical practice by placing a greater emphasis on disease prevention and the role of healthy lifestyle behaviors in disease management and remission.

RESUMO

Introduction: Mitigating the stress of graduate medical education has been the focus of residency leadership in the United States. This study examined family medicine (FM) resident and program director (PD) satisfaction with current wellness curricula, including perceptions of availability of resources and emphasis on well-being. Methods: The Council of Academic Family Medicine Educational Research Alliance administered online surveys to PDs accredited by the Accreditation Council for Graduate Medical Education, US-based FM residencies, and resident American Academy of Family Physicians members from April to May 2021. The present study included an assessment of wellness curriculum implementation using the Wellness Element Count (WEC), a satisfaction rating with wellness programming, and a single question assessing perceived changes in emphasis on wellness during COVID-19. Results: A total of 242 residents (5% response rate) and 263 PDs (42% response rate) completed the survey. Residents reported lower WEC indicators compared to PDs (P<.001). Overall, 67.8% of resident respondents were satisfied with their program's wellness efforts, compared to 89.3% of PDs ( P<.001). Perceived emphasis on wellness curricula in the program was associated with greater resident satisfaction (OR=2.75, P<.05); less emphasis on wellness was associated with less resident satisfaction (OR=0.15, P<.001). Conclusions: Residents reported overall lower perceived availability and satisfaction with program wellness efforts compared to PDs, suggesting a disparity between perspectives. Ongoing efforts should be directed at encouraging use of available wellness resources and supporting a culture of well-being.

RESUMO

BACKGROUND AND OBJECTIVES: The COVID-19 pandemic obliged the field of graduate medical education to pivot from in-person to virtual residency interviews in 2020. The decreased travel and financial barriers of this format could potentially lead to greater diversity and equity in the primary care workforce. We aimed to evaluate changes in applicant pools from in-person to virtual interviewing cycles. METHODS: We conducted a retrospective review of Electronic Residency Application Services (ERAS) from five US family medicine residencies across five interview cycles (three in-person and two virtual; 2017/2018 through 2021/2022). We compared geographic and demographic data about applicants as well as administrative program data. RESULTS: The study included 25,271 applicants. The average distance between applicants and programs was 768 miles during in-person interview years and 772 miles during virtual interview years (P=.27). Applicants who interviewed with programs were 446 and 459 miles away, respectively (P=.06). During in-person application years, applicants with backgrounds historically underrepresented in medicine (URM) submitted an average of 21% of applications; this increased approximately 1% during virtual interviewing years (OR, 1.08; P=.03). There were no other differences between in-person and virtual application years in rates of URM applicants. Residency programs received more applications from US medical schools (OR, 1.46; P<.0001) and were more likely to interview a US medical school applicant (OR, 2.26; P<.0001) in virtual years. Program fill rates appeared to be lower during virtual years. CONCLUSIONS: The virtual interviewing format did not appear to substantially increase the geographic, racial, or ethnic diversity of applicants, and was associated with increased applications from US medical schools.

RESUMO

BACKGROUND AND OBJECTIVES: Residency program directors (PDs) are tasked with supporting resident well-being, and a 2018-2019 CERA survey found PDs to be generally satisfied with residency wellness curricula. However, less is known about graduate medical education wellness programming following the unprecedented social and public health stressors of 2020. This study aimed to evaluate PDs' satisfaction with wellness programming and perceived changes in wellness program implementation in the context of these factors. METHODS: An online survey was administered by CERA to the program directors of all ACGME-accredited, US-based family medicine residencies. The survey replicated a 2018 CERA survey and assessed PDs' satisfaction with the wellness curriculum and which wellness curricular elements were currently implemented in the residency. RESULTS: The survey was completed by 263 PDs (42% response rate). There was no difference in total number of wellness curricular elements reported in programs in 2021 (M=9.85) vs 2018 (M=9.57; P=.377). Compared to the 2018 survey, PDs reported increased assessment of resident burnout (P=.02), increased scheduled time for personal needs (P=.002), but decreased scheduled time for interpersonal connection (P=.017). Most PDs reported increased emphasis on wellness and the same or increased access to wellness resources compared to 2018 χ2 indicated no significant difference in PD satisfaction with wellness programming between the two years (P=.84). CONCLUSIONS: Despite significant social and public health challenges to curriculum delivery, family medicine PDs did not perceive significant reductions in wellness programming, and in fact reported increases in some specific curricular elements and an overall increased emphasis on well-being. Future studies should explore the factors that facilitate and impede the implementation of wellness programming.

RESUMO

BACKGROUND AND OBJECTIVES: Many residency programs are developing resident wellness curricula to improve resident well-being and to meet Accreditation Council for Graduate Medical Education guidelines. However, there is limited guidance on preferred curricular components and implementation. We sought to identify how specific driving factors (eg, having an identified wellness champion with a budget and protected time to develop wellness programs) impact implementation of essential elements of a resident wellness curriculum. METHODS: We surveyed 608 family medicine residency program directors (PDs) in 2018-2019 on available resources for wellness programs, essential wellness elements being implemented, and satisfaction with wellness programming; 251 PDs provided complete responses (42.5% response rate). Linear and logistic regressions were conducted for main analyses. RESULTS: Having an identified wellness champion, protected time, and dedicated budget for wellness were associated with greater implementation of wellness programs and PD satisfaction with wellness programming; of these, funding had the strongest association. Larger programs were implementing more wellness program components. Program setting had no association with implementation. CONCLUSIONS: PDs in programs allocating money and/or faculty time can expect more wellness programming and greater satisfaction with how resident well-being is addressed.

RESUMO

BACKGROUND AND OBJECTIVES: The Association of Family Medicine Residency Directors (AFMRD) Physician Wellness Task Force released a comprehensive Well-Being Action Plan as a guide to help programs create a culture of wellness. The plan, however, does not offer a recommendation as to which elements may be most important, least resource intensive, or most feasible. This study sought to identify the most essential components of the AFMRD's Well-Being Action Plan, as rated by expert panelists using a modified Delphi technique. METHODS: Sixty-eight selected experts were asked to participate; after three rounds of surveys, the final sample included 27 participants (7% residents, 38% MD faculty, 54% behavioral science faculty). RESULTS: Fourteen elements were rated as essential by at least 80% of the participants. These components included interventions at both the system and individual level. Of those elements ranked in the top five by a majority of the panel, all but one do not mention specific curricular content, but rather discusses the nature of a wellness curriculum. CONCLUSIONS: The expert consensus was that an essential curriculum should begin early, be longitudinal, identify a champion, and provide support for self-disclosure of struggles.

RESUMO

This article was migrated. The article was marked as recommended. Background: Transition from the medical school classroom to the clinical training years requires students to adapt in many ways. Schedules are more variable, with longer clinic hours and travel to affiliated hospitals. Students are also faced with emotional needs of patients coincident with meeting demands from attending physicians. The prevalence of anxiety, depression and overall distress increases during the four years of medical school and particularly during difficult transitions. Methods: Forty medical students entering their first clinical year enrolled in a two session stress management program focused on mindfulness and coping strategies. Sessions were interactive, conducted by a psychologist, social worker and a counselor and comprised evidenced based components. Results: Twenty nine students completed the program. Baseline comparisons between dropouts and eventual completers showed that dropouts were more likely to screen positive for depression, anxiety and somatic tendencies. Program completers evidenced short term increased knowledge about mindfulness and coping and demonstrated significant decreases in anxiety and somatization at the end of the program. Conclusion: Though scheduling of any additional programs during the clinical years of medical school presents significant challenges, students who complete such a program sustain important benefits and evaluate the program positively.

RESUMO

Multidisciplinary focus group review of current triage practice identified gaps in identification of potentially infectious diseases. Modifications were made to triage and nursing assessment forms that were easy to maneuver, rapidly modifiable, and provided documentation-based decision support to expedite infection prevention measures. Development of a decision support infectious disease risk screening tool enhances outbreak preparedness, occupational safety, and response.

RESUMO

Approximately 10 % of first year medical students have clinically relevant anxiety or depression which may affect academic success and quality of life. This study tested the effects of a stress management intervention on indicators of anxiety, depression and self-efficacy in self-selected first year medical students. Forty two medical students volunteered to participate and provided informed consent. An eight session intervention was offered and focused on building relaxation skills, adaptive coping, and basic nutrition. Anxiety, depression, and self-efficacy were assessed pre and post intervention. This group of students had significantly higher baseline values of depression and anxiety but lower self-efficacy compared to a previous study of medical students at the same institution (p < 0.03). After the intervention, statistically significant improvements were observed in anxiety (p < 0.05), and self-efficacy (p < 0.05), but not in depression. The entering levels of anxiety and depression in this group suggested that these students were at risk for later clinical syndromes. Intervention directed to decreasing the effects of stress was associated with improvement in indicators of distress and may modify the longer term risk.

RESUMO

In the United States, the health of a community falls on a continuum ranging from healthy to unhealthy and fluctuates based on several variables. Research policy and public health practice literature report substantial disparities in life expectancy, morbidity, risk factors, and quality of life, as well as persistence of these disparities among segments of the population. One such way to close this gap is to streamline medical education to better prepare our future physicians for our patients in underserved communities. Medical schools have the potential to close the gap when training future physicians by providing them with the principles of social medicine that can contribute to the reduction of health disparities. Curriculum reform and systematic formative assessment and evaluative measures can be developed to match social medicine and health disparities curricula for individual medical schools, thus assuring that future physicians are being properly prepared for residency and the workforce to decrease health inequities in the United States. We propose that curriculum reform includes an ongoing social medicine component for medical students. Continued exposure, practice, and education related to social medicine across medical school will enhance the awareness and knowledge for our students. This will result in better preparation for the zero mile stone residency set forth by the Accreditation Council of Graduate Medical Education and will eventually lead to the outcome of higher quality physicians in the United States to treat diverse populations.

RESUMO

Family medicine residents are at risk for burnout due to extended work hours, lack of control over their work schedule, and challenging work situations and environments. Building resiliency can prevent burnout and may improve a resident's quality of life and health behavior. This report describes a program designed to build resiliency, the ability to bounce back from stress, in family medicine residents in a medium sized U.S. residency training program. Interactive sessions emphasized building self-awareness, coping skills, strengths and meaning in work, time management, self-care, and connections in and outside of medicine to support resident well-being. System changes which fostered wellness were also implemented. These changes included increasing the availability of fresh fruits in the conference and call room, purchasing an elliptical exercise machine for the on call room, and offering a few minutes of mindfulness meditation daily to the inpatient residents. Results to date show excellent acceptance of the program by trainees, increased consumption of nutritious foods, more personal exercise, and self-reported decreased overreactions to stress. Resiliency programs can effectively serve to meet accreditation requirements while fostering residents' abilities to balance personal and professional demands.

RESUMO

Existing literature indicates significant comorbidity between posttraumatic stress disorder (PTSD) and major depression. We examined whether PTSD's dysphoria and mood/cognitions factors, conceptualized by the empirically supported four-factor DSM-5 PTSD models, account for PTSD's inherent relationship with depression. We hypothesized that depression's somatic and non-somatic factors would be more related to PTSD's dysphoria and mood/cognitions factors than other PTSD model factors. Further, we hypothesized that PTSD's arousal would significantly mediate relations between PTSD's dysphoria and somatic/non-somatic depression. Using 181 trauma-exposed primary care patients, confirmatory factor analyses (CFA) indicated a well-fitting DSM-5 PTSD dysphoria model, DSM-5 numbing model and two-factor depression model. Both somatic and non-somatic depression factors were more related to PTSD's dysphoria and mood/cognitions factors than to re-experiencing and avoidance factors; non-somatic depression was more related to PTSD's dysphoria than PTSD's arousal factor. PTSD's arousal did not mediate the relationship between PTSD's dysphoria and somatic/non-somatic depression. Implications are discussed.

RESUMO

The identification of highly potent and orally active triazines for the inhibition of PDE10A is reported. The new analogs exhibit low-nanomolar potency for PDE10A, demonstrate high selectivity against all other members of the PDE family, and show desired drug-like properties. Employing structure-based drug design approaches, we investigated the selectivity of PDE10A inhibitors against other known PDE isoforms, by methodically exploring the various sub-regions of the PDE10A ligand binding pocket. A systematic assessment of the ADME and pharmacokinetic properties of the newly synthesized compounds has led to the design of drug-like candidates with good brain permeability and desirable drug kinetics (t(1/2), bioavailability, clearance). Compound 66 was highly potent for PDE10A (IC(50)=1.4 nM), demonstrated high selectivity (>200×) for the other PDEs, and was efficacious in animal models of psychoses; reversal of MK-801 induced hyperactivity (MED=0.1mg/kg) and conditioned avoidance responding (CAR; ID(50)=0.2 mg/kg).

RESUMO

Entering medical students experience distress symptoms due to the demands of the intensive curriculum, adjustment to new environments and increased responsibilities. The purpose of this controlled, randomized study was to determine the effects of a structured wellness program on measures of anxiety, depression and frequency of acute illness in 449 first year medical students. The effects of eight sessions of stress management were compared to a wait list control group. High risk students were identified based on scores on psychological inventories and number of recent life events (WLE). Results showed that depression, anxiety scores and frequency of acute illness were higher in women than in men, and were higher in students with multiple life events. Significant decreases were observed in depression in the intervention group students when WLE was the covariate (p = .045). Further, the high risk group showed consistently lower depression scores after the intervention compared to high risk wait list controls (p = .003), and these changes were maintained at the end of school year. There were no significant changes in anxiety or frequency of acute illness. Wellness programs can be implemented in medical school and may be particularly useful for entering students with elevated psychological distress.

RESUMO

On the basis of the previously reported benzimidazole 1,3'-bipyrrolidine benzamides (1), a new class of 2-(pyrrolidin-1-yl)ethyl-3,4-dihydroisoquinolin-1(2H)-one derivatives (3-50) were synthesized and evaluated as potent H(3) receptor antagonists. In particular, compound 39 exhibited potent in vitro binding and functional activities at the H(3) receptor, good selectivities against other neurotransmitter receptors and ion channels, acceptable pharmacokinetic properties, and a favorable in vivo profile.

RESUMO

The identification of highly potent and orally active phenylpyrazines for the inhibition of PDE10A is reported. The new analogues exhibit subnanomolar potency for PDE10A, demonstrate high selectivity against all other members of the PDE family, and show desired druglike properties. Employing structure-based drug design approaches, we methodically explored two key regions of the binding pocket of the PDE10A enzyme to alter the planarity of the parent compound 1 and optimize its affinity for PDE10A. Bulky substituents at the C9 position led to elimination of the mutagenicity of 1, while a crucial hydrogen bond interaction with Glu716 markedly enhanced its potency and selectivity. A systematic assessment of the ADME and PK properties of the new analogues led to druglike development candidates. One of the more potent compounds, 96, displayed an IC(50) for PDE10A of 0.7 nM and was active in predictive antipsychotic animal models.

RESUMO

RATIONALE: α7 nicotinic acetylcholine receptor (nAChR) agonists are proposed as candidate agents for the adjunctive treatment of cognitive deficits associated with schizophrenia. Despite the pursuit of such an approach clinically, it is surprising that the preclinical profile of pro-cognitive agents in conjunction with antipsychotic drugs is currently unexplored. OBJECTIVES: We determined if the memory-enhancing effects of the selective α7 nAChR agonist WYE-103914 were preserved in the presence of the atypical antipsychotic drug risperidone, and if the antipsychotic-like profile of risperidone was preserved in the presence of WYE-103914. METHODS: Using the rat novel object recognition (NOR) paradigm, the maintenance of memory-enhancing activity of the α7 nAChR agonist WYE-103914 in the presence of risperidone was examined. Similarly, in the standard tests of antipsychotic-like activity, apomorphine-induced climbing (AIC) in mice and conditioned avoidance responding (CAR) in rats, the preservation of antipsychotic-like activity of risperidone was evaluated in the presence of WYE-103914. RESULTS: WYE-103914 exhibited memory-enhancing activity in rat NOR, and this effect of WYE-103914 was retained in the presence of risperidone. In AIC, the atypical antipsychotic profile of risperidone was not significantly altered by WYE-103914. In contrast, WYE-103914 moderately potentiated the efficacy profile of risperidone in CAR, an effect that did not appear to be convincingly linked to a pharmacokinetic interaction. CONCLUSIONS: These data underscore the value of a preclinical evaluation of the adjunctive profile of a memory-enhancing agent in combination with antipsychotics and provide further support to augmentation with α7 nAChR agonists to address the cognitive deficits associated with schizophrenia.
