Impact of right ventricular dysfunction on outcomes in patients requiring intra-aortic balloon pump placement: A retrospective nationwide analysis (2016-2020).

Right ventricular dysfunction (RVD) continues to be a significant contributor to both mortality and morbidity, posing a significant challenge in the management of patients undergoing evaluation for mechanical circulatory support (MCS). Currently, there is a paucity of data regarding outcomes in this subset of patients. We analyzed the National Inpatient Sample database (NIS) to identify adult hospitalizations who underwent intra-aortic balloon pump (IABP) placement with or without co-existence of RVD. Multivariate logistic regression, and linear regression analyses were used to compare outcomes, and adjust for possible confounders. Out of 126,985 hospitalizations who underwent IABP placement, 1,475 (1.2%) had RVD. Patients with RVD who received an IABP had higher adjusted odds of inpatient mortality (Adjusted odds ratio [aOR]: 2.33, 95% confidence interval [CI]: 1.7-3.2, p<0.001) than those without co-existing RVD. Hospitalized patients who underwent IABP placement with RVD had higher adjusted odds of worse hospitalization outcomes in general. Conducting additional prospective studies and clinical trials with an emphasis on further subcategorization of patients with RVD is crucial for determining optimal management strategies for these patients.

The Impact of an Intern's Clinical Guidebook on Easing the Transition of New Interns Into the United States Healthcare System.

This study explores the efficacy of an intern's clinical guidebook in facilitating the transition of categorical internal medicine interns into the United States healthcare system. New interns, particularly foreign medical graduates, face multifaceted challenges during their initial year of residency. The research, conducted at Ascension Saint Joseph Hospital in Chicago, employed a quasi-experimental pre-post design involving 20 interns. Participants were provided with an intern's clinical guidebook, and their knowledge was assessed through pre and post exams. Results demonstrated a statistically significant improvement in overall knowledge, with mean scores increasing from 65% to 77.37%. Subgroup analysis revealed similar improvements among both male and female interns. Data confidentiality and ethical considerations were prioritized, with participant data anonymized and stored securely. Despite limitations, this study highlights the guidebook's potential to enhance intern education and improve the quality of care provided during the crucial transition period. Further research is recommended to validate and extend these findings.

High-Grade Pure Esophageal Neuroendocrine Carcinoma Arising From Barrett's Mucosa: A Rare Phenomenon.

Esophageal neuroendocrine carcinoma (E-NEC) is a very rare neuroendocrine tumor. There are only a few case reports where pure esophageal NEC is found to be arising from Barett's mucosa. Here we present a case of high-grade pure E-NEC arising from Barrett's esophagus, which was metastasized to the liver at the time of diagnosis.

Sarcomatoid Intrahepatic Cholangiocarcinoma: A Rare and Aggressive Primary Liver Cancer.

Sarcomatoid intrahepatic cholangiocarcinoma (S-iCCA) is a rare variant of primary liver cancer with a poor prognosis due to local aggressive expansion and frequent metastases. The pathogenesis remains unclear, but theories suggest epithelial-mesenchymal transition, biphasic differentiation of pluripotent stem cells, or sarcomatoid re-differentiation of immature multipotent carcinoma cells. Chronic hepatitis B and C, cirrhosis, and age above 40 are plausible contributors. Diagnosis of S-iCCA requires immunohistochemical evidence of both mesenchymal and epithelial molecular expression. Early detection and total resection are the current mainstay approach. We report a case of metastatic S-iCCA in a 53-year-old male with alcohol use disorder who underwent en bloc right hepatic lobectomy, right adrenalectomy, and cholecystectomy.
