Goal: This research aimed to evaluate variations in perceived organizational support among physicians during the first year of the COVID-19 pandemic and the associations between perceived organizational support, physician burnout, and professional fulfillment. Methods: Between November 20, 2020, and March 23, 2021, 1,162 of 3,671 physicians (31.7%) responded to the study survey by mail, and 6,348 of 90,000 (7.1%) responded to an online version. Burnout was assessed using the Maslach Burnout Inventory, and perceived organizational support was assessed by questions developed and previously tested by the Stanford Medicine WellMD Center. Professional fulfillment was measured using the Stanford Professional Fulfillment Index. Principal Findings: Responses to organizational support questions were received from 5,933 physicians. The mean organizational support score (OSS) for male physicians was higher than the mean OSS for female physicians (5.99 vs. 5.41, respectively, on a 0–10 scale, higher score favorable; p < .001). On multivariable analysis controlling for demographic and professional factors, female physicians (odds ratio [OR] 0.66; 95% CI: 0.55–0.78) and physicians with children under 18 years of age (OR 0.72; 95% CI: 0.56–0.91) had lower odds of an OSS in the top quartile (i.e., a high OSS score). Specialty was also associated with perceived OSS in mean-variance analysis, with some specialties (e.g., pathology and dermatology) more likely to perceive significant organizational support relative to the reference specialty (i.e., internal medicine subspecialty) and others (e.g., anesthesiology and emergency medicine) less likely to perceive support. Physicians who worked more hours per week (OR for each additional hour/week 0.99; 95% CI: 0.99–1.00) were less likely to have an OSS in the top quartile. On multivariable analysis, adjusting for personal and professional factors, each one-point increase in OSS was associated with 21% lower odds of burnout (OR 0.79; 95% CI: 0.77–0.81) and 32% higher odds of professional fulfillment (OR 1.32; 95% CI: 1.28–1.36). Practical Applications: Perceived organizational support of physicians during the COVID-19 pandemic was associated with a lower risk of burnout and a higher likelihood of professional fulfillment. Women physicians, physicians with children under 18 years of age, physicians in certain specialties, and physicians working more hours reported lower perceived organizational support. These gaps must be addressed in conjunction with broad efforts to improve organizational support.

Background: Within the spectrum of gastroesophageal reflux disease (GERD), pathologic reflux applies to the subset of patients with either erosive esophagitis or abnormal esophageal acid exposure on pH-metry, consequences of a dysfunctional antireflux barrier (ARB). Methods: The American Foregut Society (AFS) tasked a 13-member working group of expert foregut surgeons and esophagologists (The ARB Cooperative) to develop a white paper on ARB function, dysfunction, and mechanisms of action of antireflux surgery through discussion of relevant literature summarized herein. Results: The ARB Cooperative concluded that pathologic reflux is a consequence of the interplay between progressive anatomical distortion of the ARB and physiology. Factors contributing to ARB dysfunction include (1) separation of crural diaphragm from the lower esophageal sphincter with widening of the hiatus and diminished crural diaphragm sphincteric function; (2) loss of the intra-abdominal lower esophageal sphincter segment with complete disabling of the flap valve component of the ARB; (3) axial hiatal hernia leading to reflux during swallow-induced lower esophageal sphincter (LES) relaxation, LES hypotension, inspiration related reflux, a lowered threshold for eliciting transient LES relaxations, and increased compliance of the gastroesophageal junction leading to greater diameter of sphincter opening during transient LES relaxations. With regard to antireflux surgery, the objectives include: (1) reduction of hiatal hernia and restoration of the intra-abdominal esophageal segment; (2) repair of the dilated hiatus; (3) restoring flap valve function by modifying gastroesophageal anatomy; and (4) restricting gastroesophageal junction opening during periods of relaxation. Conclusions: This ARB Cooperative white paper supports the concept of there being 3 major inter-related mechanisms promoting ARB competence: the LES as an intrinsic sphincter, the crural diaphragm as an extrinsic sphincter, and the gastroesophageal valve, a mechanical 1-way valve. Pathological reflux occurs with progressive anatomical disruption of the ARB which in turn leads to physiological dysfunction, the severity of which parallels the extent of anatomical disruption. The corollary of this is that the primary mechanism of antireflux surgery is to restore the ARB by eliminating or compensating for its anatomical disruption. It is the hope of the cooperative that understanding the proposed framework will help clinicians and researchers in improving antireflux procedures.

The objective of this project was to develop a standardized list of renally eliminated and potentially nephrotoxic drugs that will help inform initiatives to improve medication safety. Several available lists of medications from the published literature including original research articles and reviews, and from regulatory agencies, tertiary references, and clinical decision support systems were compiled, consolidated, and compared. Only systemically administered medications were included. Medication combinations were included if at least 1 active ingredient was considered renally dosed or potentially nephrotoxic. The medication list was reviewed for completeness and clinical appropriateness by a multidisciplinary team of individuals with expertise in critical care, nephrology, and pharmacy. An initial list of renally dosed and nephrotoxic drugs was created. After reconciliation and consensus from clinical experts, a standardized list of 681 drugs is proposed. The proposed evidence-based standardized list of renally dosed and potentially nephrotoxic drugs will be useful to harmonize epidemiologic and medication quality improvement studies. In addition, the list can be used for clinical purposes with surveillance in nephrotoxin stewardship programs. We suggest an iterative re-evaluation of the list with emerging literature and new medications on an approximately annual basis.

Abstract Background In the TOPAZ-1, patients with biliary tract cancers (BTC) and recurrence within 6 months after surgery were excluded, even if this event is frequently observed in clinical practice. Our study aimed to assess if the efficacy of cisplatin-gemcitabine-durvalumab (CGD) in this population is comparable to that reported in the phase 3 trial. Methods The study cohort included patients with BTC who underwent surgery on the primary tumor, experienced disease recurrence occurring ≤6 months or &gt;6 months after surgery or after the end of adjuvant therapy and started CGD. The primary objectives were overall survival (OS) and progression free survival (PFS). Results A total of 178 patients were enrolled. No significant differences were observed between early and late relapse groups in OS (23.4 months vs not reached; HR 1.26; 95% CI, 0.67-2.37; P = .45) and PFS [7.0 months vs 9.8 months; HR 1.3(95% CI, 0.9-2.1) P = .13]. Overall response rate and disease control rate (P = .33 and P = .62) were comparable between the 2 groups, as the overall safety profile. In addition, we compared survival outcomes between the selected population and a historical cohort of patients with BTC treated with cisplatin-gemcitabine (CG) and found that despite the absence of statistical significance, CGD showed an outcome trend compared with CG regardless of the time of recurrence after surgery or adjuvant chemotherapy [(CG ≤ 6 vs CGD ≤ 6 months: HR 0.59, 95%CI, 0.35-1.01, P = .05; HR 0.70; 95%CI, 0.46-1.06, P = .09, OS and PFS, respectively) and (CG &gt; 6 vs. CGD &gt; 6 months: HR 0.50; 95%CI, 0.29-0.88, P = 0.0165; HR 0.54; 95%CI, 0.35-0.84, P = .0068, OS and PFS, respectively)]. Conclusion Our analysis suggests that CGD retains its efficacy independently of the timing of relapse after surgery or completion of adjuvant treatment in patients with advanced BTC.

Background: With neck, aging the cervicomental angle becomes obtuse and may be influenced by hyoid bone aging. An understanding of hyoid position changes with aging will further our understanding of its role in neck contour changes. Methods: A 3D volumetric reconstruction of 282 neck computed tomography scans was performed. The cohort was categorized into three groups based on age: 20 years or older and younger than 40 years, 40 years or older and younger than 60 years, and 60 years or older and younger than 80 years. The vertical and horizontal hyoid distances in relation to the mandible were calculated for each patient. Results: A total of 282 patients (153 women, 129 men) were included in the cohort. The age groups were evenly distributed in men and women. Mean hyoid vertical and horizontal distances differed between women and men in all age groups. There was a significant difference in the hyoid vertical distance between 20–39 years old to 40–59 years old in men (P < 0.01), and 20–39 years old to 60–79 years old in both genders (women P = 0.005, men P < 0.01). Hyoid horizontal distance was not affected by age and sex (age and sex: P > 0.05), but rather by body mass index (BMI). Every 5 BMI points corresponded to a forward movement of 2 mm. Conclusions: As individuals age, the hyoid bone descends in both sexes, and an increase in BMI is associated with forward movement. Additional studies are needed to assess the correlation of the hyoid position between upright and supine positions.

PURPOSE Imlunestrant is a next-generation oral selective estrogen receptor (ER) degrader designed to deliver continuous ER target inhibition, including in ESR1- mutant breast cancer. This phase Ia/b trial determined the recommended phase II dose (RP2D), safety, pharmacokinetics, and efficacy of imlunestrant, as monotherapy and in combination with targeted therapy, in ER-positive (ER+) advanced breast cancer (ABC) and endometrial endometrioid cancer. The ER+/human epidermal growth factor receptor 2–negative (HER2–) ABC experience is reported here. METHODS An i3+3 dose-escalation design was used, followed by dose expansions of imlunestrant as monotherapy or in combination with abemaciclib with or without aromatase inhibitor (AI), everolimus, or alpelisib. Imlunestrant was administered orally once daily and with the combination partner per label. RESULTS Overall, 262 patients with ER+/HER2– ABC were treated (phase Ia, n = 74; phase Ib, n = 188). Among patients who received imlunestrant monotherapy (n = 114), no dose-limiting toxicities or discontinuations occurred. At the RP2D (400 mg once daily), patients (n = 51) reported grade 1-2 nausea (39.2%), fatigue (39.2%), and diarrhea (29.4%). Patients at RP2D had received previous cyclin-dependent kinase 4/6 inhibitor (CDK4/6i; 92.2%), fulvestrant (41.2%), and chemotherapy (29.4%) for ABC and achieved a median progression-free survival (mPFS) of 7.2 months (95% CI, 3.7 to 8.3). Among patients who received imlunestrant + abemaciclib (n = 42) and imlunestrant + abemaciclib + AI (n = 43), most (69.4%) were treatment-naïve for ABC; all were CDK4/6i-naïve. Patients treated with imlunestrant + everolimus (n = 42)/alpelisib (n = 21) had received previous CDK4/6i (100%), fulvestrant (34.9%), and chemotherapy (17.5%) for ABC. No new safety signals or interactions with partnered drugs were observed. The mPFS was 19.2 months (95% CI, 13.8 to not available) for imlunestrant + abemaciclib and was not reached for imlunestrant + abemaciclib + AI. The mPFS with imlunestrant + everolimus/alpelisib was 15.9 months (95% CI, 11.3 to 19.1)/9.2 months (95% CI, 3.7 to 11.1). Antitumor activity was evident regardless of ESR1 mutation status. CONCLUSION Imlunestrant, as monotherapy or in combination with targeted therapy, had a manageable safety profile with evidence of preliminary antitumor activity in ER+/HER2– ABC.

Abstract During the past several decades, medical education research has advanced in many ways. However, the field has struggled somewhat with translating knowledge into practice. The field has tremendous potential to generate insights that may improve educational outcomes, enhance teaching experiences, reduce costs, promote equity, and inform policy. However, the gap between research and practice requires attention and reflection. In this commentary, the authors reflect on ways that medical education researchers can balance relevance and rigor, while discussing a potential path forward. First, medical education research can learn from implementation science, which focuses on adopting and sustaining best practices in real-world settings. Second, gaining a deeper understanding of the complex and dynamic ways that medical education contexts may influence the uptake of research findings into practice would facilitate the translation and mobilization of knowledge into practical settings. Third, moving from unilateral knowledge translation to participatory knowledge mobilization and engaging diverse stakeholders as active participants in the research process can also enhance impact and influence research findings. Overall, for medical education research to effect meaningful change, it must transition from producing generalizable findings to generating context-specific insights and embracing participatory knowledge mobilization. This shift will involve rethinking traditional research approaches and fostering collaboration with knowledge users to cocreate and implement innovative solutions tailored to their unique settings.

Background Gastrointestinal cancers comprise nearly one-third of global mortality from cancer, yet the comprehensive global burden of these cancers remains uninvestigated. Objective We aimed to assess the global, regional and national burden of gastrointestinal cancers. Designs Data on oesophagus, gastric, colorectal, liver, pancreas and biliary tract cancers were extracted from the Global Burden of Disease 2021 database. Age-standardised incidence rate (ASIR) and age-standardised death rate (ASDR) were calculated by sex, region and Sociodemographic Index (SDI). Results In 2021, there were 5.26 million incidences and 3.70 million deaths from gastrointestinal cancer. The greatest burden is from colorectal, followed by gastric, oesophageal, pancreatic, liver and biliary tract cancer. We noted geographical and socioeconomic differences in ASIR and ASDR across all types of cancers. From 2000 to 2021, ASIR increased for colorectal cancer (annual percent change (APC): 0.10%, 95% CI 0.05% to 0.14%), pancreatic cancer (APC: 0.27%, 95% CI 0.14% to 0.41%), and liver cancer from metabolic dysfunction-associated steatotic liver disease (APC: 0.62%, 95% CI 0.58% to 0.67%) and alcohol-related liver disease (APC: 0.26%, 95% CI 0.22% to 0.30%). ASDR increased for pancreatic cancer (APC: 0.18%, 95% CI 0.02% to 0.34%). Higher SDI countries had higher incidence rates for most types of gastrointestinal cancer. Conclusions Although the ASIR of oesophageal, gastric and biliary tract cancer has decreased, the ASIR still increased in colorectal, pancreatic and liver cancer from steatotic liver disease. Public policies are important for controlling gastrointestinal cancers—most importantly, reducing alcohol consumption, hepatitis B immunisation and tackling the burden of metabolic diseases.

Abstract Purpose To examine graduating medical student reports of burnout by sex, race and ethnicity, and sexual orientation and explore trends within intersectional demographic groups from 2019–2021 in a national sample. Method The authors obtained medical student responses to the 2019–2021 Association of American Medical Colleges (AAMC) Graduation Questionnaires (GQs) linked to data from other AAMC sources. The dataset included year of GQ completion, responses to a modified Oldenburg Burnout Inventory (exhaustion subscale range: 0–24; disengagement subscale range: 0–15), and demographics previously shown to relate to the risk of burnout in medical students, residents, or physicians. Multivariable linear regression analysis was performed to evaluate independent associations between demographics and burnout. Results Overall response rate was 80.7%. After controlling for other factors, mean exhaustion scores were higher among Asian (parameter estimate [PE] 0.38, 95% confidence interval [CI] 0.21, 0.54), bisexual (PE 0.97, 95% CI 0.76, 1.17), and gay or lesbian (PE 0.55, 95% CI 0.35, 0.75) students than those who did not identify with each of those respective groups. Mean disengagement scores were lower among female (PE −0.47, 95% CI −0.52, −0.42), Hispanic (PE −0.11, 95% CI −0.22, −0.01), and White (PE −0.10, 95% CI −0.19, 0.00) students and higher among Asian (PE 0.17, 95% CI 0.07, 0.27), Black or African American (PE 0.31, 95% CI 0.18, 0.44), bisexual (PE 0.54, 95% CI 0.41, 0.66), and gay or lesbian (PE 0.23, 95% CI 0.11, 0.35) students than those who did not identify with each of those respective groups. From 2019–2021, mean exhaustion and disengagement scores were relatively stable or improved across nearly all intersectional groups. Conclusions Male, Asian, Black or African American, and sexual minority students had a higher risk of burnout, while female, Hispanic, White, and heterosexual or straight students had a lower risk of burnout.

Abstract Purpose This study describes the structure and timing of the clinical education components of MD-PhD programs to illustrate how variations in preclerkship curriculum correlate with the opportunity for early clinical exposure and other key program characteristics. Method A survey was disseminated to U.S. MD-PhD programs on May 25, 2022, asking about the preclerkship curriculum length (long [&gt; 18 months], medium [13–18 months], or short [12 months]), United States Medical Licensing Examination Step 1 timing (relative to the PhD training and clerkships), and opportunity for clerkships before the PhD phase. This survey was supplemented with data from publicly available sources to include 92 MD-PhD programs. Results This study found a wide range of MD-PhD clinical curricula. A strong association was found between shorter preclerkship curriculum length and the opportunity for clerkships before the PhD (10 of 50 programs [20%] with long preclerkship curriculum, 19 of 35 programs [54%] with medium preclerkship curriculum, and 7 of 7 programs [100%] with short preclerkship curriculum; P &lt; .001). Variations in United States Medical Licensing Examination Step 1 timing also exist based on preclerkship curriculum length and the opportunity for clerkships before the PhD. Shorter preclerkship curriculum length was associated with National Institutes of Health funding of the MD-PhD program (20 [40%] of long, 25 [69%] of medium, and 6 [86%] of short preclerkship curricula; P = .006) and larger MD-PhD program size (35 students with long, 70 with medium, and 86 with short preclerkship curricula; P &lt; .001). Preclerkship curriculum length was not associated with public vs private medical schools, although the West had shorter preclerkship curricula. Conclusions This study underscores the need for collaborative efforts to gain insights into the effectiveness and implications of educational interventions in MD-PhD programs, ultimately informing future training strategies and policies.
