Systemized approach to equipping medical students with naloxone: a student-driven initiative to combat the opioid crisis.

BACKGROUND: Naloxone is an effective and safe opioid reversal medication now approved by the U.S. Food and Drug Administration (FDA) for use with or without a prescription. Despite this, naloxone dissemination lags at a time when U.S. opioid-related mortality expands. The authors proposed distributing naloxone to all U.S. medical students using established statewide standing prescription orders for naloxone, eliminating the financial burden of over-the-counter costs on students and streamlining workflow for the pharmacy. By focusing naloxone distribution on medical students, we are able to capitalize on a group that is already primed on healthcare intervention, while also working to combat stigma in the emerging physician workforce. METHODS: Beginning August 2022, the authors established a partnership between Harvard Medical School (HMS) and the outpatient pharmacy at Brigham and Women's Hospital (BWH) to facilitate access to naloxone for HMS medical students. BWH developed a HIPAA-secure electronic form to collect individual prescription information. BWH pharmacists processed submissions daily, integrating the naloxone prescription requests into their workflow for in-person pick-up or mail-order delivery. The electronic form was disseminated to medical students through a required longitudinal addiction medicine curriculum, listserv messaging, and an extracurricular harm reduction workshop. RESULTS: Over the 2022-2023 academic year, 63 medical students obtained naloxone kits (two doses per kit) through this collaboration. CONCLUSIONS: We propose that medical schools advocate for a hospital pharmacy-initiated workflow focused on convenience and accessibility to expand naloxone access to medical students as a strategy to strengthen the U.S. emergency response and prevention efforts aimed at reducing opioid-related morbidity and mortality. Expansion of our program to BWH internal medicine residents increased our distribution to over 110 healthcare workers, and efforts to expand the program to other BWH training programs and clinical sites such as the emergency department and outpatient infectious disease clinics are underway. With more than 90,000 medical students in the U.S., we believe that widespread implementation of targeted naloxone training and distribution to this population is an accessible approach to combating the public health crisis of opioid-related overdoses.

Preferred language and disease severity predict evaluation for liver transplantation among patients admitted with alcohol-associated hepatitis.

BACKGROUND: Liver transplantation (LT) for alcohol-associated hepatitis (AH) is a relatively new practice and limited work exists surrounding the role social determinants of health may play in evaluation. This includes language that defines how patients interact with the healthcare system. We explored characteristics of patients with AH evaluated for LT within an integrated health system. METHODS: Using a system-wide registry, we identified admissions for AH from 1 January 2016 to 31 July 2021. A multivariable logistic regression model was developed to evaluate independent predictors of LT evaluation. RESULTS: Among 1723 patients with AH, 95 patients (5.5%) underwent evaluation for LT. Evaluated patients were more likely have English as their preferred language (95.8% vs 87.9%, P = 0.020), and had higher INR (2.0 vs 1.4, P < 0.001) and bilirubin (6.2 vs 2.9, P < 0.001). AH patients who underwent evaluation had a lower burden of mood and stress disorders (10.5% vs 19.2%, P < 0.05). Patients with English preferred language had a greater than three times adjusted odds of LT evaluation compared with all others when adjusting for clinical disease severity, insurance status, sex, and psychiatric comorbid conditions (OR, 3.20; 95% CI, 1.14-9.02). CONCLUSION: Patients with AH evaluated for LT were more likely to have English as their preferred language, more psychiatric comorbidities, and more severe liver disease. Despite adjustment for psychiatric comorbidities and disease severity, English preferred language remained the strongest predictor of evaluation. As programs expand LT for AH, it is vital to build equitable systems that account for the interaction between language and healthcare in transplantation.

Glucose absorption drives cystogenesis in a human organoid-on-chip model of polycystic kidney disease.

In polycystic kidney disease (PKD), fluid-filled cysts arise from tubules in kidneys and other organs. Human kidney organoids can reconstitute PKD cystogenesis in a genetically specific way, but the mechanisms underlying cystogenesis remain elusive. Here we show that subjecting organoids to fluid shear stress in a PKD-on-a-chip microphysiological system promotes cyst expansion via an absorptive rather than a secretory pathway. A diffusive static condition partially substitutes for fluid flow, implicating volume and solute concentration as key mediators of this effect. Surprisingly, cyst-lining epithelia in organoids polarize outwards towards the media, arguing against a secretory mechanism. Rather, cyst formation is driven by glucose transport into lumens of outwards-facing epithelia, which can be blocked pharmacologically. In PKD mice, glucose is imported through cysts into the renal interstitium, which detaches from tubules to license expansion. Thus, absorption can mediate PKD cyst growth in human organoids, with implications for disease mechanism and potential for therapy development.

Acceptability and utility of a virtual pediatric transplant peer mentoring program: A mixed-methods analysis of a novel quality improvement program.

BACKGROUND: Adolescent transplant patients are at increased risk for graft loss at a period when they also suffer from illness-related social isolation, which has been exacerbated by the COVID-19 pandemic. The Peer Mentoring Program (PMP), developed in 2018, was adapted to a virtual format in 2020 due to COVID-19. Our objective is to evaluate the acceptability, utility, and potential impact of the in-person and virtual versions of the PMP on participants. METHODS: We performed convergent mixed-methods analysis of the experiences of patients participating in the PMP for quality improvement purposes. RESULTS: Surveys and focus group invitations were sent to 18 current program participants, with 17 patients responding to the survey and 13 patients participating in focus groups. In this study, 82% were satisfied and 88% would recommend PMP; 76% identified other PMP members as people they would like to keep in touch with. Qualitative analysis revealed three themes: (1) a supportive community of peers, (2) reduced isolation, and (3) receiving accurate information from providers. CONCLUSIONS: There is a prominent need for greater peer support among adolescent transplant patients transitioning to adulthood, especially with the increased isolation associated with COVID-19. The virtual adaptation could be an important, permanent supplement to in-person events.

Predictors for Nonhome Patient Discharge following Lower Extremity Arterial Interventions.

PURPOSE: To identify the variables associated with patient discharge disposition to optimize postprocedural care and discharge planning following lower extremity arterial interventions for peripheral artery disease (PAD). MATERIALS AND METHODS: The 2014-2017 American College of Surgeons National Surgical Quality Improvement Program database was queried using current procedural terminology codes for endovascular infrainguinal interventions for PAD. The main outcome variable of interest was nonhome discharge. Covariates included patient sociodemographic variables, age quartile (upper quartile, ≥77 years), comorbidities (diabetes, renal disease, bleeding disorder, congestive heart failure [CHF], and chronic obstructive pulmonary disease), presence of an open wound before a procedure, type of procedure, operative time, symptom severity, American Society of Anesthesiologists class, and baseline functional status. Univariate analysis and multivariate logistic regression were performed on Stata/SE 15.1. RESULTS: A total of 3,190 patients met the inclusion criteria, of whom 664 (20.8%) had nonhome discharge. Multivariate regression revealed that age (odds ratio [OR], 1.9 for the upper age quartile [>77 years]; 95% confidence interval [CI], 1.46-2.50), operative time (OR, 1.2 per increase in quartile; 95% CI, 1.09-1.30), preoperative wound (OR, 1.5; 95% CI, 1.24-1.90), renal failure (OR, 1.7; 95% CI, 1.30-2.14), CHF (OR, 2.2; 95% CI, 1.51-3.24), symptom severity (OR, 1.7; 95% CI, 1.46-1.98), and independent functional status (OR, 0.74; 95% CI, 0.59-0.92; P = .007) were associated with nonhome discharge. All P values were ≤.001 unless otherwise stated. CONCLUSIONS: Prolonged procedural time, the presence of preprocedural wound and patient comorbidities, symptomatology, and baseline functional status may be used to identify patients who will require a nonhome discharge and early discharge planning.

Utility of the RENAL Nephrometry Scoring System in Predicting Adverse Events and Outcomes of Percutaneous Microwave Ablation of Renal Tumors.

PURPOSE: To assess the utility of the radius, exophytic/endophytic, nearness to collecting system or sinus, anterior/posterior, and location relative to polar lines (RENAL) nephrometry scoring system at predicting adverse events and outcomes in percutaneous microwave ablation (MWA) of renal tumors. MATERIALS AND METHODS: A retrospective review of 116 patients who underwent MWA from 2004 to 2018 at 2 large university hospitals was conducted. Patient demographics and tumor characteristics were collected. The RENAL nephrometry scores were calculated, and procedure-related adverse events were stratified into minor and major (the Society of Interventional Radiology classification of class C or higher). Technical and oncologic outcomes were based on follow-up magnetic resonance imaging and computed tomography scans after ablation. RESULTS: The mean RENAL score was 6.6 (range, 4-11), and the mean tumor size was 24 mm. Follow-up ranged between 16 and 161 weeks (median, 50 weeks; mean, 65 weeks). Oncologic control was achieved in 96% (n = 111) of patients. The major and minor adverse event rates were 8.6% (n = 10) and 17% (n = 19), respectively. The mean RENAL score for patients with recurrent and/or residual tumor (8.2 ± 2.7) was higher than that for patients without disease recurrence (6.5 ± 3.5, P = .05). However, in a multivariate analysis, the RENAL score was not found to be an independent predictor of oncologic outcomes (odds ratio, 1.548; P = .092). CONCLUSIONS: The RENAL nephrometry score has minimal utility for predicting outcomes and adverse events in MWA of renal tumors. The inconsistent nature of RENAL nephrometry scoring in percutaneous ablation procedures underscores the need for an ablation-specific risk stratification system.

Gender-Based Survey Analysis of Research and Mentoring in Interventional Radiology.

PURPOSE: This study sought to define gender-related differences in attitudes, perceptions, and aspirations among trainees interested in interventional radiology (IR) and to analyze their experiences in research and mentorship. MATERIALS AND METHODS: A cross-sectional survey study was conducted among the members of the Society of Interventional Radiology Resident, Fellow, and Student section and Medical Student section in the summer of 2020. The anonymous, internally validated 27-item survey assessed demographics, research attitudes and experiences, mentorship, and career aspirations. Descriptive statistics were calculated using Fisher exact analyses and Student t-tests. The institutional review board approved the protocols for this study. RESULTS: Of 105 respondents who indicated their gender, 30% were women and 70% were men. Although both genders reported similar levels of research experience, female trainees were less likely to feel valued and encouraged by their institution to engage in research (2.79 out of 4 vs 3.16 out of 4, P = .02) and were less likely to indicate that their program required them to participate in research (2.47 vs 3.06, P = .01). Female residents and fellows reported more difficulty in finding a mentor (2.88 vs 3.28, P = .04) and received less mentorship relating to IR education (29% vs 64%, P = .002). CONCLUSIONS: This work provides a perspective on the perceived obstacles faced by female trainees in pursuing research and finding effective mentorship in the field of IR. These data may guide future interventions to boost interest and engagement in IR research and residency programs in a way that promotes gender diversity and equity in the field.

Quantifying Risk Tolerance Among Potential Living Kidney Donors With the Donor-Specific Risk Questionnaire.

RATIONALE & OBJECTIVE: Enhanced informed consent tools improve patient engagement. A novel visual aid measured potential donors' risk tolerance to postdonation kidney failure and assessed if the closeness of the relationship to the intended recipient altered willingness to accept risk. STUDY DESIGN: Cross-sectional analysis of donor evaluations at the time of enrollment into a longitudinal mixed-methods study between November 2014 and February 2016. SETTING & PARTICIPANTS: Three US kidney transplant centers. English-speaking adults presenting for in-person living kidney donor evaluation. EXPOSURE: Closeness of the relationship between the potential living donor and intended recipient. OUTCOME: Willingness to accept postdonation kidney failure. ANALYTICAL APPROACH: The Donor-Specific Risk Questionnaire, a dot matrix visual diagram, was used to measure willingness to accept kidney failure risk. Multivariable logistic regression assessed associations between risk acceptance and data from social science instruments, which measured donors' perceived closeness with the recipient. Qualitative data were analyzed thematically per grounded theory. RESULTS: 307 participants (response rate: 86%) completed testing. 96% indicated a willingness to accept a risk of kidney failure of 0.9% or greater. Those who were older (OR, 0.98 [95% CI, 0.96-0.99]), women (OR, 0.54 [95% CI, 0.31-0.93]), and Black (OR, 0.25 [95% CI, 0.08-0.76]) were less likely to be in the medium versus low willingness to accept risk group. Closeness of the relationship to the recipient was independently associated with greater risk acceptance (for every 1-point greater closeness score, odds ratios for being in the medium and high willingness to accept risk groups were 1.21 [95% CI, 1.03-1.41] and 2.42 [95% CI, 1.53-3.82] compared with being in the low willingness to accept risk group). With the exception of parental relationships, biological linkages were not associated with accepting higher kidney failure risk. LIMITATIONS: First demonstration of visual aid that used one risk estimate of kidney failure provided to all participants. Risk estimates were not customized to different demographic groups. CONCLUSIONS: Relationship closeness was independently associated with a greater willingness to accept postdonation kidney failure. Visual aids can provide transplant teams with individualized donor perspectives on risk thresholds and can potentially facilitate greater patient-centered care for living donors.
