Analysis of immune-related adverse events in gastrointestinal malignancy patients treated with immune checkpoint inhibitors.

Immune checkpoint inhibitors are becoming an increasingly common treatment for advanced gastrointestinal cancer, but the possibility of immune-related adverse events has raised concerns. This study aimed to evaluate the risks of immune-related adverse events between patients who received immune checkpoint inhibitors and those who received chemotherapy among different types of gastrointestinal cancer. The study utilized data from the multicenter TriNetX database in the United States covering the period between 2015 and 2022. Hazard ratios and 95% confidence intervals were used to describe the relative hazard of immune-related adverse events based on comparing time-to-event rates. Our study revealed that the incidence of immune-related adverse events was significantly higher in patients who received immune checkpoint inhibitors and chemotherapy compared to those who received chemotherapy only in treating gastrointestinal cancer. CTLA-4 inhibitors tended to have a higher rate of immune-related adverse events compared to PD-1/PD-L1 inhibitors. Our study found a lower mortality rate among patients who developed immune-related adverse events compared to those who did not after propensity score matching (HR, 0.661; 95% CI 0.620-0.704; p < .01). We provide important real-world data on the incidence and impact of immune-related adverse events in patients with advanced gastrointestinal cancer treated with immune checkpoint inhibitors. Our study's results support clinicians in making informed decisions about the potential benefits and risks of immune checkpoint inhibitor therapy for patients with gastrointestinal cancer.

Reduction of cardiovascular complications during delivery hospitalization in patients undergoing bariatric procedures.

BACKGROUND: The global surge in obesity presents a significant health challenge, leading to increased adoption of bariatric surgery as an intervention. However, the correlation between bariatric surgery and cardiovascular outcomes during subsequent pregnancies remains unclear. The aim of our study was to determine the prevalence of cardiovascular complications during delivery hospitalizations in patients with bariatric procedure. METHODS: We performed a retrospective analysis utilizing the National Inpatient Sample database to examine data from delivery admissions of pregnant women with obesity and a history of bariatric surgery. These admissions were identified using International Classification of Diseases (ICD) codes from 2009 to 2019. In comparing pregnant individuals who had undergone bariatric surgery with those with obesity but had no such surgical history, we assessed the prevalence of cardiovascular complications. RESULTS: Our study included 3,027,987 pregnancies in individuals with obesity and an additional 117,350 pregnancies following bariatric surgery. Compared to patients without bariatric surgery, post-surgery patients were older (32.84 years vs 29.02 years), primarily White (59.0%), and mostly treated in large urban hospitals. Cardiovascular outcomes showcased reduced odds of congestive heart failure [Adjusted odds ratios (AOR) 0.11, 95% confidence intervals (CI) 0.01-0.74], gestational hypertensive complications (AOR 0.55, 95% CI 0.53-0.59), and cardiac arrhythmia (AOR 0.76, 95% CI 0.64-0.89) in the post-surgery group, with no significant difference in peripartum cardiomyopathy rates (AOR 0.72, 95% CI 0.29-1.76) and no instances of stroke or acute MI. Perinatally, the surgery cohort had higher odds of preterm birth (AOR 1.30, 95% CI 1.24-1.38) and fetal growth restriction (AOR 2.47, 95% CI 2.32-2.63) but fewer incidents of being large for gestational-age (AOR 0.35, 95% CI 0.32-0.38). As bariatric surgery became increasingly recognized as a significant factor in certain complications, its prevalence among the study population increased from 2009 to 2019. CONCLUSION: In summary, our research indicates that bariatric surgery is associated with a decreased risk of cardiovascular complications during delivery. This study highlights how insights from bariatric surgery outcomes could shape clinical guidelines for managing obesity in pregnant women.

The Cost of a Learner in the Pediatric Emergency Department: A Comparison Across Two Pediatric Emergency Departments.

OBJECTIVES: Experimental learning is a foundation of medical education, but a learner in the pediatric emergency department impacts utilization, time and disposition metrics. Our study sought to compare the effect of a resident learner on metrics between 2 pediatric emergency departments. METHODS: This retrospective study was conducted in 2019 in 2 pediatric emergency departments of tertiary care hospitals. We compared various time, utilization, and disposition metrics between resident-covered and nonresident-covered patients. RESULTS: A total of 62,548 patient encounters were included in our analysis, with 8102 (13%) encounters were resident-managed. Residents were consistently found to see higher-acuity patients, which led to increased relative value unit generation. Residents used more diagnostic testing consistently across both sites. However, we found significant differences between time and disposition metrics between the 2 sites. CONCLUSIONS: Residents see sicker patients and tend to order more ancillary tests, which ultimately leads to increased relative value unit generation. We hypothesize that the difference in metrics seen could be explained by the training background of residents, as well as efficiencies of the department as a whole.

Early palliative care referral may improve end-of-life care in end-stage liver disease patients: A retrospective analysis from a non-transplant center.

BACKGROUND: Patients with end-stage liver disease (ESLD) who are not transplant candidates often have a trajectory of rapid decline and death similar to patients with stage IV cancer. Palliative care (PC) services have been shown to be underutilized for such patients. Most studies examining the role of PC in ESLD have been done at transplant centers. Thus, determining the utilization and benefit of PC at a non-transplant tertiary center may help establish a standard of care in the management of patients with ESLD not eligible for transplant. METHODS: We conducted a retrospective analysis of adult (>18 years) patients with ESLD admitted to Rochester Regional Health (RRH) system hospitals from 2012 to 2021. Patients were divided into groups based on the presence or absence of PC involvement. Baseline characteristics were recorded. The impact of PC was assessed by comparing the number of hospitalizations before and after the involvement of PC, comparing code status changes, health care proxy (HCP) assignments, Aspira catheter placements, and frequency of repeated paracentesis. RESULTS: In our analysis of 576 patients, 41.1% (237 patients) received a PC consult (PC group), while 58.9% (339 patients) did not (no-PC group). Baseline characteristics were comparable. However, their mean number of admissions significantly decreased (15.66 vs. 3.49, p < 0.001) after PC involvement. Full code status was more prevalent in the no-PC group (67.8% vs. 18.6%, p < 0.001), while comfort care code status was more common in the PC group (59.9% vs. 20.6%, p < 0.001). Changes in code status were significantly higher in the PC group (77.6% vs. 29.2%, p < 0.001). The PC group had a significantly higher mortality rate (83.1% vs. 46.4%, p < 0.01). Patients in the PC group had a higher likelihood of having an assigned HCP (63.7% vs. 37.5%, p < 0.001). PC referral was associated with more frequent use of an Aspira catheter (5.9% vs. 0.9%, p < 0.001) and more frequent paracentesis (30.8% vs. 16.8%, p < 0.001). CONCLUSIONS: In conclusion, our study provides compelling evidence of the diverse advantages of palliative care for patients with end-stage liver disease, including reduced admissions, improved goals of care, code status modifications, enhanced healthcare proxy assignments, and targeted interventions. These findings highlight the potential significance of early integration of palliative care in the disease trajectory to provide comprehensive, patient-centered care that addresses the unique needs and preferences of individuals with advanced liver disease.

Systematic Review with Meta-analysis: Efficacy and Safety of Upadacitinib in Managing Moderate-to-Severe Crohn's Disease and Ulcerative Colitis.

BACKGROUND: In the panorama of therapeutic strategies for inflammatory bowel diseases, oral upadacitinib stands out for its potential to improve short-term and long-term patient outcomes. OBJECTIVE: This meta-analysis aspires to collate and assess the available evidence regarding the efficacy and safety of upadacitinib in managing moderate-to-severe Crohn's disease and ulcerative colitis. METHODS: A meta-analysis was conducted using studies sourced from MEDLINE/PubMed, Cochrane Library, Scopus, and Embase, published from January 2010 to March 2024. Peer-reviewed articles that reported data on the effects of upadacitinib in adult patients with Crohn's disease and ulcerative colitis were included based on established inclusion and exclusion criteria. RESULTS: Eight studies, encompassing a total of 2818 patients treated with upadacitinib, were included. In primary outcomes, for patients with Crohn's disease who were using upadacitinib, the weighted pooled clinical remission rate was found to be 45.8% (95% confidence interval [CI] 0.39-0.52), while for patients with ulcerative colitis who were using upadacitinib, the rate was 25.4% (95% CI 0.17-0.36). The pooled clinical response rate for Crohn's disease was 53.6% (95% CI 0.50-0.57), and for ulcerative colitis it was 72.6% (95% CI 0.69-0.76). The pooled serious adverse event rate was 6.0% (95% CI 0.07-0.09). CONCLUSIONS: Upadacitinib demonstrates significant efficacy in achieving clinical remission and response in patients with moderate-to-severe Crohn's disease and ulcerative colitis, as shown by clinical remission rates of 44.9% and 36.0%, respectively. The treatment also maintains a favorable safety profile with a serious adverse event rate of 7.8%, making it an effective option for those resistant or intolerant to traditional immunosuppressants or tumor necrosis factor antagonists.

Impact of anticoagulation therapy on outcomes in patients with cirrhosis and portal vein thrombosis: A large-scale retrospective cohort study.

INTRODUCTION: Portal vein thrombosis in cirrhotic patients presents a significant clinical challenge. This study aims to (1) explore the impact of anticoagulation therapy on patient outcomes; (2) comparative outcomes in portal vein thrombosis treated between direct oral anticoagulant and Vitamin K Antagonist (VKA). MATERIALS AND METHODS: We leveraged the TriNetX database to analyze a cohort comprising 4224 patients with liver cirrhosis and PVT who were treated with anticoagulation, alongside a comparison group of 15,300 patients with the same conditions but not receiving anticoagulation therapy. RESULTS: The anticoagulated group showed a significant reduction in mortality (27.9 % vs. 34.2 %, HR = 0.723, 95 % CI: 0.678-0.770, P < 0.001). When comparing direct oral anticoagulant versus. VKA, in compensated liver cirrhosis, the direct oral anticoagulant group exhibited significantly lower mortality rates compared to VKA (17.7 % vs. 26.5 %, HR = 0.655, 95 % CI: 0.452-0.951, P = 0.025), with no significant difference in liver transplantation rates (4.0 % vs. 4.7 %, P = 0.080). In decompensated liver cirrhosis, the direct oral anticoagulant group exhibited lower mortality compared to the VKA group (23.6 % vs. 30.6 %, HR = 0.732, 95 % CI: 0.629-0.851, P < 0.001), and a higher frequency of liver transplantation was observed in the VKA group (10.6 % vs. 16.0 %, HR = 0.622, 95 % CI: 0.494-0.784, P < 0.001). Hospitalization rates were significantly lower in the direct oral anticoagulant group compared to the VKA group in decompensated cirrhosis (33.4 % vs. 38.3 %, HR = 0.830, 95 % CI: 0.695-0.992, P = 1.937). CONCLUSIONS: Our study offers compelling evidence supporting the use of anticoagulation therapy in liver cirrhosis with portal vein thrombosis. The use of DOACs in patients with both compensated and decompensated liver cirrhosis showed a marked mortality benefit.

A Case of Painless Subacute Thyroiditis Presenting as Fever of Unknown Origin.

Subacute thyroiditis (SAT) is characterized by severe pain in the anterior aspect of the neck and tenderness is present during the thyroid gland's palpation. It is commonly caused by viruses including mumps, measles, rubella, coxsackievirus, influenza, and Epstein-Barr virus (EBV). Painless subacute thyroiditis is rare and can present as a fever of unknown origin (FUO). Our case reports an unusual case of SAT as our patient did not have any neck pain. Laboratory investigations show low thyroid-stimulating hormone (TSH), poor or no uptake of radioactive iodine by the thyroid, and elevated erythrocyte sedimentation rate (ESR). Clinicians should be aware that painless SAT can present as a fever of unknown origin.

Invasive Aspergillosis Masquerading as Multiple Pulmonary Nodules: A Challenging Diagnosis.

Invasive pulmonary aspergillosis (IPA) is an aggressive fungal infection of the lungs characterized by tissue invasion by fungal hyphal elements. The definitive diagnosis is challenging because it relies on histopathological demonstration of fungal elements, and these days clinicians are relying more on bronchoalveolar lavage (BAL) cultures and serum biomarkers (galactomannan and beta-D-glucan). We would like to emphasize through our case the necessity to keep a high index of suspicion for IPA despite negative cultures and serum biomarkers in immunosuppressed patients and consider surgical biopsy early.

Interventions to improve resident reporting of patient safety events: a quality improvement initiative.

BACKGROUND: Patient safety events (PSE) are opportunities to improve patient care but physicians rarely report them. In a previous study, residents identified knowledge regarding what constitutes a PSE, perceived lack of time, complexity of the reporting process, lack of feedback, and perceived failure to resolve the issue despite reporting to be barriers limiting their PSE reporting. The residency programs and system patient safety and quality improvement departments created targeted interventions to address identified barriers. OBJECTIVE: Assess effectiveness of targeted interventions on improving PSE reporting rates amongst residents. METHODS: As part of a multi-residency patient safety project, interventions were created to focus on the removal of barriers to reporting PSE identified previously. Post-interventions, an identical cross-sectional survey of the residents at the same two community teaching hospitals was conducted from Sept to Dec 2018 through an online questionnaire tool. RESULTS: 78 out of 149 residents (52.3%) completed the survey. We found a significant improvement in the number of residents who endorsed reporting a PSE in the past 1 year (51.2% vs 23.5%, p = 0.001), as well as during the course of their training (52.6% vs 26.5%, P = 0.001). There was also a significant decrease in the number of residents who were unsure of how to report a PSE (p = 0.031) as well as those who viewed medical error as a sign of incompetence (p = 0.036). CONCLUSION: Our study demonstrates that simplifying the PSE reporting process, improving knowledge and acceptance of patient safety/quality improvement principles and promotion of a just culture improves resident PSE reporting.

Internal medicine resident perspectives on scoring USMLE as pass/fail.

BACKGROUND: The scoring rubric on the USMLE Step 1 examination will be changing to pass/fail in January 2022. This study elicits internal medicine resident perspectives on USMLE pass/fail scoring at the national level. OBJECTIVE: To assess internal medicine resident opinions regarding USMLE pass/fail scoring and examine how variables such as gender, scores on USMLE 1 and 2, PGY status and type of medical school are associated with these results. METHODS: In the fall of 2019, the authors surveyed current internal medicine residents via an on-line tool distributed through their program directors. Respondents indicated their Step 1 and Step 2 Clinical Knowledge scores from five categorical ranges. Questions on medical school type, year of training year, and gender were included. The results were analyzed utilizing Pearson Chi-square testing and multivariable logistic regression. RESULTS: 4012 residents responded, reflecting 13% of internal medicine residents currently training in the USA. Fifty-five percent of respondents disagreed/strongly disagreed with pass/fail scoring and 34% agreed/strongly agreed. Group-based differences were significant for gender, PGY level, Step 1 score, and medical school type; a higher percentage of males, those training at the PGY1 level, and graduates of international medical schools (IMGs) disagreed with pass/fail reporting. In addition, high scorers on Step 1 were more likely to disagree with pass/fail reporting than low scoring residents. CONCLUSION: Our results suggest that a majority of internal medicine residents, currently training in the USA prefer that USMLE numerical scoring is retained and not changed to pass/fail.

Physician attire: physicians perspectives on attire in a community hospital setting among non-surgical specialties.

Background: Several studies have demonstrated a patient preference for physicians wearing a white coat associated with improved patient satisfaction. There are few studies on physicians' perceptions of attire mainly done in the outpatient and surgical specialties. Objective: Assess non-surgical physicians' perception of attire in the hospital and to identify if any difference in the choice of attire amongst generation X and millennial physicians. Methods: We surveyed 86 physicians in the hospital with six sets of pictures of commonly worn physician attires in the hospital setting with a two-part questionnaire. Key Results: Formal attire with a white coat was found to be most favored, followed by formal without a white coat. Casual attire without a white coat was the least preferred across the surveyed attributes. The results were similar in generation X and millennial physicians. Only 49% concordance was observed with what physicians preferred and what they wore. Conclusion: Our study showed that physicians felt wearing a white coat was the best to convey specific attributes like honesty, confidence, professionalism, among others, similar to prior studies done in patients. However, less than half of the physicians surveyed themselves followed the preferred attire.

Cost of a learner in pediatric ED.

Background: Experiential learning in a cornerstone of medical education, but impacts throughput, utilization of resources and patient outcomes. Objectives: Our study sought to determine the cost of a resident across various throughput, utilization, and patient outcome measures. Methods: This retrospective study was conducted in 2016 in the pediatric emergency department of an urban tertiary care hospital. . We compared various throughput, utilization and patient outcome measures between resident-covered and nonresident-covered patients. A subgroup analysis was performed based on complexity as determined by CPT codes. Results: 33,278 patient encounters occurred between 1 January 2016, and 31 December 2016. Of these, 8,434 (25.42%) were resident-covered patients. Across all encounters, throughput, utilization and patient experience measures were unfavorable for the resident covered group. In subgroup analysis based on complexity of patients, throughput measures were either unfavorable or there was a trend towards unfavorability across all complexities for the resident covered group. Overall utilization and patient outcome measures were unfavorable in low and moderate complexity patients for the resident covered group. In high complexity patients, most of the utilization and patient outcome measures were similar in both groups. Conclusion: Presence of a resident led to unfavorable increases in many throughput, utilization and outcome measures, a difference which disappeared in most cases with higher complexity patients. Therefore, the cost of a resident may actually decrease with increasing patient complexity.

Provider Decisions to Treat Respiratory Illnesses with Antibiotics: Insights from a Randomized Controlled Trial.

RATIONALE: Lower respiratory tract illness (LRTI) frequently causes adult hospitalization and antibiotic overuse. Procalcitonin (PCT) treatment algorithms have been used successfully in Europe to safely reduce antibiotic use for LRTI but have not been adopted in the United States. We recently performed a feasibility study for a randomized clinical trial (RCT) of PCT and viral testing to guide therapy for non-pneumonic LRTI. OBJECTIVE: The primary objective of the current study was to understand factors influencing PCT algorithm adherence during the RCT and evaluate factors influencing provider antibiotic prescribing practices for LRTI. STUDY DESIGN: From October 2013-April 2014, 300 patients hospitalized at a community teaching hospital with non-pneumonic LRTI were randomized to standard or PCT-guided care with viral PCR testing. Algorithm adherence data was collected and multivariate stepwise logistic regression of clinical variables used to model algorithm compliance. 134 providers were surveyed anonymously before and after the trial to assess knowledge of biomarkers and viral testing and antibiotic prescribing practices. RESULTS: Diagnosis of pneumonia on admission was the only variable significantly associated with non-adherence [7% (adherence) vs. 26% (nonadherence), p = 0.01]. Surveys confirmed possible infiltrate on chest radiograph as important for provider decisions, as were severity of illness, positive sputum culture, abnormal CBC and fever. However, age, patient expectations and medical-legal concerns were also at least somewhat important to prescribing practices. Physician agreement with the importance of viral and PCT testing increased from 42% to 64% (p = 0.007) and 49% to 74% (p = 0.001), respectively, after the study. CONCLUSIONS: Optimal algorithm adherence will be important for definitive PCT intervention trials in the US to determine if PCT guided algorithms result in better outcomes than reliance on traditional clinical variables. Factors influencing treatment decisions such as patient age, presence of fever, patient expectations and medical legal concerns may be amenable to education to improve PCT algorithm compliance for LRTI.

Nurse-driven, protocol-directed weaning from mechanical ventilation improves clinical outcomes and is well accepted by intensive care unit physicians.

PURPOSE: Ventilator weaning protocols can improve clinical outcomes, but their impact may vary depending on intensive care unit (ICU) structure, staffing, and acceptability by ICU physicians. This study was undertaken to examine their relationship. DESIGN/METHODS: We prospectively examined outcomes of 102 mechanically ventilated patients for more than 24 hours and weaned using nurse-driven protocol-directed approach (nurse-driven group) in an intensivist-led ICU with low respiratory therapist staffing and compared them with a historic control of 100 patients who received conventional physician-driven weaning (physician-driven group). We administered a survey to assess ICU physicians' attitude. RESULTS: Median durations of mechanical ventilation (MV) in the nurse-driven and physician-driven groups were 2 and 4 days, respectively (P = .001). Median durations of ICU length of stay (LOS) in the nurse-driven and physician-driven groups were 5 and 7 days, respectively (P = .01). Time of extubation was 2 hours and 13 minutes earlier in the nurse-driven group (P < .001). There was no difference in hospital LOS, hospital mortality, rates of ventilator-associated pneumonia, or reintubation rates between the 2 groups. We identified 4 independent predictors of weaning duration: nurse-driven weaning, Acute Physiology and Chronic Health Evaluation II score, vasoactive medications use, and blood transfusion. Intensive care unit physicians viewed this protocol implementation positively (mean scores, 1.59-1.87 on a 5-point Likert scale). CONCLUSIONS: A protocol for liberation from MV driven by ICU nurses decreased the duration of MV and ICU LOS in mechanically ventilated patients for more than 24 hours without adverse effects and was well accepted by ICU physicians.
