Contextualizing the Resurgence of U.S. Housestaff Union Activity.

ABSTRACT: There is a growing trend of resident and fellow physician unionization in the United States, with 14 new housestaff unions formed at private employers since 2022. This resurgence of housestaff union organizing parallels the last era of housestaff activism in the 1960s. Today's housestaff organizing takes place within the context of longstanding challenges in medicine, including the burnout and systemic inequities highlighted by the COVID-19 pandemic, and an increase in national activism and labor organizing. Housestaff unions offer opportunities for residents and fellows to negotiate for improvements across multiple issues.In this Commentary, the authors focus on common bargaining topics: poor working conditions, undercompensation, and inadequate representation in an increasingly corporatized health care landscape. The authors also discuss the role of collective bargaining for improving the housestaff experience and address common concerns about unionization. Finally, the authors explore the limited evidence of the impact of unions in health care settings and outline key considerations for future scholarship.The current generation of housestaff started their medical careers with an awareness of systemic challenges to the profession and have responded through collective organizing. While the short- and long-term ramifications of housestaff organizing need further study, the authors express optimism that unionization will lead to improved working conditions and thus improved health care delivery.

Education About Specialty Palliative Care Among Nonhealthcare Workers: A Systematic Review.

CONTEXT: Despite the expansion of palliative care (PC) services, the public has little knowledge and holds misperceptions about PC, creating barriers to accessing timely specialty PC. OBJECTIVES: To systematically review the evidence regarding the efficacy of educational interventions to improve knowledge and attitudes about PC among nonhealthcare workers. METHODS: We searched five databases (PubMed/MEDLINE, Embase, CIANHL, Web of Science, and Scopus) for studies investigating educational interventions about specialty PC in adults who identified as patients, caregivers, or members of the public. We included studies that were available in English and had a comparator group. We excluded studies that only sampled health professionals or children. We used the Mixed Methods Appraisal Tool to assess quality and risk of bias. RESULTS: Of 12,420 records identified, we screened 5948 abstracts and assessed 526 full texts for eligibility. Twenty-one articles were extracted for analysis, representing 20 unique educational interventions. Common methodologies included quasi-experimental (9, 45%), randomized controlled trial (4, 20%), and nonrandomized trial (2, 10%). Common components of the educational interventions included video presentations (9, 45%), written materials (8, 40%), and lectures (4, 20%). Content included definition (14, 70%) and philosophy (14, 70%) of PC, distinctions between PC and hospice (11, 55%), and eligibility for PC (11, 55%). Fourteen (70%) interventions showed statistically significant positive differences in either knowledge or attitudes about PC. CONCLUSIONS: While educational interventions can positively impact knowledge and attitudes about PC among nonhealthcare workers, more research is needed to inform the design, delivery, and evaluation of interventions to increase knowledge and attitudes about PC.

Voice Assistants' Responses to Questions About the COVID-19 Vaccine: National Cross-sectional Study.

BACKGROUND: Artificial intelligence-powered voice assistants (VAs), such as Apple Siri, Google Assistant, and Amazon Alexa, interact with users in natural language and are capable of responding to simple commands, searching the internet, and answering questions. Despite being an increasingly popular way for the public to access health information, VAs could be a source of ambiguous or potentially biased information. OBJECTIVE: In response to the ongoing prevalence of vaccine misinformation and disinformation, this study aims to evaluate how smartphone VAs respond to information- and recommendation-seeking inquiries regarding the COVID-19 vaccine. METHODS: A national cross-sectional survey of English-speaking adults who owned a smartphone with a VA installed was conducted online from April 22 to 28, 2021. The primary outcomes were the VAs' responses to 2 questions: "Should I get the COVID vaccine?" and "Is the COVID vaccine safe?" Directed content analysis was used to assign a negative, neutral, or positive connotation to each response and website title provided by the VAs. Statistical significance was assessed using the t test (parametric) or Mann-Whitney U (nonparametric) test for continuous variables and the chi-square or Fisher exact test for categorical variables. RESULTS: Of the 466 survey respondents included in the final analysis, 404 (86.7%) used Apple Siri, 53 (11.4%) used Google Assistant, and 9 (1.9%) used Amazon Alexa. In response to the question "Is the COVID vaccine safe?" 419 (89.9%) users received a direct response, of which 408 (97.3%) had a positive connotation encouraging users to get vaccinated. Of the websites presented, only 5.3% (11/207) had a positive connotation and 94.7% (196/207) had a neutral connotation. In response to the question "Should I get the COVID vaccine?" 93.1% (434/466) of users received a list of websites, of which 91.5% (1155/1262) had a neutral connotation. For both COVID-19 vaccine-related questions, there was no association between the connotation of a response and the age, gender, zip code, race or ethnicity, and education level of the respondent. CONCLUSIONS: Our study found that VAs were much more likely to respond directly with positive connotations to the question "Is the COVID vaccine safe?" but not respond directly and provide a list of websites with neutral connotations to the question "Should I get the COVID vaccine?" To our knowledge, this is the first study to evaluate how VAs respond to both information- and recommendation-seeking inquiries regarding the COVID-19 vaccine. These findings add to our growing understanding of both the opportunities and pitfalls of VAs in supporting public health information dissemination.

Using Wearable Biosensors to Predict Length of Stay for Patients with IBD After Bowel Surgery.

BACKGROUND AND AIMS: It remains unknown whether ambulation or sleep predicts postoperative length of stay for patients with IBD. We aim to identify the utility of wearable biosensors in predicting postoperative length of stay for patients with IBD. METHODS: Associations of postoperative length of stay with step count/sleep duration/sleep efficiency measured by wearable biosensors were examined. The best-fitting multivariable linear regression model predicting length of stay was constructed using stepwise model selection. RESULTS: Final sample included 37 patients. Shorter sleep duration on postoperative day 4 (r = 0.51, p = 0.043) or 5 (r = 0.81, p = 0.0045) or higher sleep efficiency on postoperative day 5 (r = - 0.77, p = 0.0098) was associated with a shorter length of stay. Additionally, a more positive change in sleep efficiency from postoperative day 4-5 was associated with a shorter length of stay (r = - 0.77, p = 0.024). The best-fitting multivariable linear regression model revealed Clavien-Dindo grade 1 (p = 0.045) and interaction between Clavien-Dindo grade 2/3a and mean daily steps (p = 0.00038) are significant predictors of length of stay. The following variables were not significantly associated with length of stay: mean daily steps/sleep duration/sleep efficiency, average rate of change in these three variables, and changes in step count between successive postoperative days 1-5, sleep duration between successive postoperative days 2-5, and sleep efficiency between successive postoperative days 2-4. CONCLUSION: We demonstrated the utility of activity and sleep data from wearable biosensors in predicting length of stay. Patients with more severe complications may benefit more (i.e., reduced postoperative length of stay) from increased ambulation. However, overall, sleep duration/efficiency did not predict length of stay.

Cumulative Histologic Inflammation Predicts Colorectal Neoplasia in Ulcerative Colitis: A Validation Study.

BACKGROUND: Chronic inflammation in ulcerative colitis (UC) is associated with the development of colorectal neoplasia (CRN). A group at St. Mark's Hospital reported a novel cumulative inflammatory index that predicted the development of CRN in UC patients that we validated with an independent, well-described, matched, case-controlled cohort from the University of Chicago. METHODS: Cumulative inflammatory burden (CIB) was calculated by summing each histological inflammatory activity (HIA) score and multiplying it by the length of the surveillance interval. Persistency was defined by the number of surveillance episodes (with a severity score >2) divided by the total number of surveillance procedures. T tests compared the mean and maximum HIA scores, assessing mean and maximum severity, CIB, and persistency. RESULTS: Sixty-two UC patients (26 patients with CRN, 36 control patients without CRN) were analyzed. Fifty-five percent were men, mean disease duration was 20.6 years, and mean age at CRN diagnosis was 43.9. Of the CRN patients, 6 (23%) had colorectal cancer, 16 (62%) had low-grade dysplasia, and 4 (15%) had indefinite dysplasia. Using mean HIA scores, we found CIB to be statistically greater in CRN patients (P = 0.04). Using maximum HIA scores, we found CIB (P = 0.02), mean severity (P = 0.03), and persistency (P = 0.01) to be significantly greater in CRN patients. Maximum severity was numerically greater for mean and maximum HIA scores but did not reach significance. CONCLUSION: Cumulative histologic inflammation is significantly associated with the development of CRN in UC patients. This suggests a management strategy of controlling inflammation to reduce the risk of CRN and may influence the selection of surveillance intervals.

Black Race and Public Insurance Are Predictive of Inappropriate Evaluation of Iron Deficiency Anemia and Diarrhea.

BACKGROUND AND AIMS: Socioeconomic status, race, and insurance can impact healthcare delivery and utilization in several chronic disease states. The primary aim of our study was to determine whether race and insurance status are predictors of having an appropriate workup for celiac disease and inflammatory bowel disease (IBD) when presenting with iron deficiency anemia (IDA) and chronic diarrhea. METHODS: Medical records of patients seen at the University of Chicago Medical Center between January 1, 2006, and September 20, 2017, were reviewed. Patients with two separate encounters within 6 months associated with the diagnosis codes for both IDA and chronic diarrhea were identified. Patients without a diagnosis code for IBD and celiac disease were further grouped as those that had an "appropriate" workup and those that did not. Factors associated with the appropriate evaluation were analyzed by univariate and multivariate logistic regression. RESULTS: In total, 899,701 records were searched. A total of 83 patients fit inclusion into the study (8 IBD, 3 CD, 72 neither IBD or CD). Black race was associated with a 91% decreased odds of having the appropriate workup on univariate (OR 0.090, 95%CI 0.017-0.475, p = 0.005) and age-adjusted multivariate analysis (OR 0.095, 95% CI 0.017-0.527, p = 0.007). Public insurance status was significantly associated with a 90% decreased odds of appropriate workup on univariate (OR 0.102, 95% CI 0.024-0.438, p = 0.002) and age-adjusted multivariate analysis (OR 0.104, 95% CI 0.021-0.513, p = 0.005). CONCLUSIONS: Black race and public insurance were significantly associated with not having an appropriate workup for IBD and celiac disease when presenting with iron deficiency and chronic diarrhea.

Efficacy and safety of induction therapy with calcineurin inhibitors followed by vedolizumab maintenance in 71 patients with severe steroid-refractory ulcerative colitis.

BACKGROUND: Following induction therapy with a calcineurin inhibitor (CNI) in severe ulcerative colitis, transitioning to vedolizumab as maintenance therapy could be an option. AIM: To report on the largest cohort of patients successfully induced with CNIs who were transitioned to vedolizumab maintenance therapy. METHODS: This is a retrospective observational study of adult patients with severe steroid-refractory ulcerative colitis. Patients were included if they were induced with a CNI followed by maintenance therapy with vedolizumab between January 2014 and December 2018. The primary endpoint was colectomy-free survival. Secondary endpoints included survival without vedolizumab discontinuation as well as clinical, steroid-free and biochemical remission at week 14. RESULTS: A total of 71 patients (59% male) were treated with vedolizumab after induction therapy with CNIs for severe steroid-refractory colitis. Patients were followed for a median time of 25 months (IQR 16-36). Colectomy-free survival rates from vedolizumab initiation were 93% at 3 months, 67% at 1 year and 55% at 2 years. At the end of induction with vedolizumab at week 14, 50% of patients were in clinical remission, and 62% of patients had a normal CRP. At 1 and 2 years following vedolizumab initiation, 43% and 28% of patients were still on vedolizumab respectively. Vedolizumab was dose escalated to infusions every 4 weeks in 44% of patients. The median time to dose escalation was 5.6 months (IQR 4.1-8.2). No serious adverse events were recorded in our patient cohort. CONCLUSIONS: Transitioning to vedolizumab following induction of remission with CNIs is effective and safe.

Long-Duration Oral Vancomycin to Treat Clostridioides difficile in Patients With Inflammatory Bowel Disease Is Associated With a Low Rate of Recurrence.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) are susceptible to Clostridioides difficile infections (CDIs), suffering from greater morbidity and mortality than the general population. Previous studies have proven the efficacy of oral vancomycin therapy in CDI, but there are no definitive guidelines to treat patients with IBD. We assessed the relationship between the length of vancomycin therapy and rates of CDI recurrence and reinfection in patients with IBD. METHODS: We compared rates of CDI recurrence and reinfection in Crohn's disease and ulcerative colitis (UC) patients receiving long-duration (LD) and short-duration (SD) oral vancomycin therapy, defined as 21-42 days and 10-14 days, respectively. Recurrence and reinfection were defined as positive C. difficile toxin assay by polymerase chain reaction within 8 weeks of the end of antibiotic therapy and after 8 weeks of the end of antibiotic therapy, respectively. The Fisher exact test was used to test for significance, and multivariate logistic regression models were constructed to control for other covariables. RESULTS: One hundred thirty-four patients with IBD (57 ulcerative colitis and 77 Crohn's disease) met inclusion criteria. LD vancomycin had a 1.8% incidence of CDI recurrence, compared with 11.7% in the SD vancomycin group (odds ratio = 0.13, P = 0.043). CDI reinfection rates and time to reinfection were not significantly different (LD 14.0% vs SD 16.9%, P = NS). Multivariate logistic regression models showed that treatment with LD vancomycin had lower odds for recurrence than SD vancomycin (odds ratio = 0.03, P = 0.021). DISCUSSION: LD vancomycin is associated with lower rates of CDI recurrence compared with SD vancomycin therapy. These results will help guide clinical decisions and the development of a prospective trial.

Low-Dose Metronidazole is Associated With a Decreased Rate of Endoscopic Recurrence of Crohn's Disease After Ileal Resection: A Retrospective Cohort Study.

BACKGROUND AND AIMS: Recurrence of Crohn's disease after surgical resection and primary anastomosis is an important clinical challenge. Previous studies have demonstrated the benefit of imidazole antibiotics, but have been limited by adverse events and medication intolerance. We evaluated whether administration of low-dose metronidazole [250 mg three times per day] for 3 months reduces endoscopic postoperative recurrence rates. METHODS: We performed a retrospective cohort study of patients with Crohn's disease who underwent ileal resection with a primary anastomosis and subsequently received care at our center. We compared the cases who received low-dose metronidazole for 3 months with control patients who did not receive this therapy. Data collected included demographics, risk factors for recurrence, and medications before and after surgery. The primary end point was the number of patients with ≥i2 [Rutgeerts] endoscopic recurrence by 12 months. Variables found to be predictive in univariate analysis at p < 0.10 were introduced in the Cox model for multivariate analysis. RESULTS: In all, 70 patients with Crohn's disease [35 cases and 35 controls] met inclusion criteria. Risk factors for Crohn's recurrence were similar between groups. The number of patients with ≥i2 endoscopic recurrence within 12 months following ileal resection was significantly lower in the metronidazole group [7 of 35 patients; 20%] compared with the number in the control group [19 of 35 patients; 54.3%] [p = 0.0058]. Eight participants [22.9%] in the metronidazole group experienced adverse events, and 3 of these patients [8.6%] discontinued the therapy. CONCLUSION: Low-dose metronidazole reduces endoscopic recurrence of Crohn's disease postoperatively and is well tolerated. This intervention should be considered as a therapy option following ileocolonic resection.

Real-World Experience with Tofacitinib in IBD at a Tertiary Center.

BACKGROUND AND AIMS: Many inflammatory bowel disease (IBD) patients do not respond to medical therapy. Tofacitinib is a first-in-class, partially selective inhibitor of Janus kinase, recently approved for treating patients with ulcerative colitis (UC). We describe our experience with the use of tofacitinib for treatment of patients with moderate-to-severe IBD. METHODS: This is a retrospective, observational study of the use of tofacitinib in IBD. Patients with medically resistant IBD were treated orally with 5 mg or 10 mg twice daily. Clinical response and adverse events were assessed at 8, 26, and 52 weeks. Objective response was assessed endoscopically, radiologically, and biochemically. RESULTS: 58 patients (53 UC, 4 Crohn's, 1 pouchitis) completed at least 8 weeks of treatment with tofacitinib. 93% of the patients previously failed treatment with anti-TNF. At 8 weeks of treatment, 21 patients (36%) achieved a clinical response, and 19 (33%) achieved clinical remission. Steroid-free remission at 8 weeks was achieved in 15 patients (26%). Of the 48 patients followed for 26 weeks, 21% had clinical, steroid-free remission. Of the 26 patients followed for 12 months, 27% were in clinical, steroid-free remission. Twelve episodes of systemic infections were noted, mostly while on concomitant steroids. One episode of herpes zoster infection was noted during follow-up. CONCLUSIONS: In this cohort of patients with moderate-to-severe, anti-TNF resistant IBD, tofacitinib induced clinical response in 69% of the patients. 27% were in clinical, steroid-free remission by 1 year of treatment. Tofacitinib is an effective therapeutic option for this challenging patient population.

Abnormal Pouchogram Predicts Pouch Failure Even in Asymptomatic Patients.

BACKGROUND: Anastomotic complications after restorative total proctocolectomy with IPAA for ulcerative colitis alter functional outcomes and quality of life and may lead to pouch failure. Routine contrast enema of the pouch assesses anastomotic integrity before ileostomy reversal, but its clinical use is challenged. OBJECTIVE: The purpose of this research was to assess the relationship among preoperative clinical characteristics, abnormal pouchography, and long-term pouch complications. DESIGN: This was a retrospective chart review. SETTINGS: The study was conducted at a tertiary care center between 2000 and 2010. PATIENTS: Ulcerative colitis patients with IPAA undergoing pouchography before ileostomy closure were included. MAIN OUTCOME MEASURES: Patient demographics, incidence of pouch-related complications, and findings on pouchogram were recorded. Primary outcome was pouch failure, defined as excision or permanent diversion of the ileoanal pouch. Independent predictors of pouch failure were determined by multivariate regression. RESULTS: A total of 262 patients with ulcerative colitis were included. Contrast extravasation was seen in 27 patients (10.3%): 14 (51.9%) were clinically asymptomatic at the time of pouchogram. Six (22.2%) of 27 patients with extravasation developed pouch failure despite normalization of the pouchogram before ileostomy closure. Forty patients (15.3%) were found to have pouch-anal anastomotic stenosis; only 1 developed pouch failure. Pre-IPAA serum albumin and hemoglobin levels were inversely associated with contrast extravasation (serum albumin: OR = 0.42; hemoglobin: OR = 0.77; p < 0.05). Contrast extravasation was associated with delayed takedown operation (average = 67 d), increased risk (OR = 5.25; p < 0.01), and shorter time (median = 32.0 vs 72.5 mo; HR = 5.88; p < 0.05) to pouch failure, as well as increased risk of pouch-related complications (p < 0.05). LIMITATIONS: The study was limited by its retrospective nature and small number of patients who developed pouch failure. CONCLUSIONS: Pouchography before ileostomy takedown is useful in identifying patients with ulcerative colitis at risk for postoperative complications. Radiologic resolution of IPAA-related leak does not reliably predict healing; caution is warranted in this subgroup. See Video Abstract at http://links.lww.com/DCR/A818.

Dietary aflatoxin-induced stunting in a novel rat model: evidence for toxin-induced liver injury and hepatic growth hormone resistance.

BACKGROUND: Despite a strong statistical correlation between dietary aflatoxin B1 (AFB1)-exposure and childhood stunting, the causal mechanism remains speculative. This issue is important because of emerging interest in reduction of human aflatoxin exposure to diminish the prevalence and complications of stunting. Pediatric liver diseases cause growth impairment, and AFB1 is hepatotoxic. Thus, liver injury might mediate AFB1-associated growth impairment. We have developed a rat model of dietary AFB1-induced stunting to investigate these questions. METHODS: Newly-weaned rats were given AFB1-supplemented- or control-diets from age 3-9 wk, and then euthanized for serum- and tissue-collection. Food intake and weight were serially assessed, with tibial-length determined at the experimental endpoint. Serum AFB1-adducts, hepatic gene and protein expression, and liver injury markers were quantified using established methodologies. RESULTS: AFB1-albumin adducts correlated with dietary toxin contamination, but such contamination did not affect food consumption. AFB1-exposed animals exhibited dose-dependent wasting and stunting, liver pathology, and suppression of hepatic targets of growth hormone (GH) signaling, but did not display increased mortality. CONCLUSION: These data establish toxin-dependent liver injury and hepatic GH-resistance as candidate mechanisms by which AFB1-exposure causes growth impairment in this mammalian model. Interrogation of modifiers of stunting using this model could guide interventions in at-risk and affected children.
