Preliminary diagnostic criteria for distinguishing metaplastic Warthin tumors from mucoepidermoid carcinomas rich in lymphoid stroma
DOI: 10.31744/einstein_journal/2026AO1591
Highlights ■ Immunohistochemistry distinguishes Warthin-like mucoepidermoid carcinoma from metaplastic Warthin tumor. ■ CK7, mitochondrial patterns, and double-layer epithelium suggest metaplastic Warthin tumor. ■ Basal CK14, CK5/6, and p63 distinguish metaplastic Warthin tumor from Warthin-like mucoepidermoid carcinoma. ABSTRACT Objective: This study aimed to analyze the clinicopathological and immunohistochemical profiles of unconventional Warthin tumors and mucoepidermoid carcinomas. Methods: Eleven low-grade salivary gland tumors with Warthin-like features were analyzed. Group A (n=6) showed a double-layered oncocytic epithelium in less than 50% of the […]

Accuracy of oxidative stress markers for predicting delayed graft function lasting longer than a week in deceased-donor kidney transplantation
DOI: 10.31744/einstein_journal/2026AO1827
Highlights ■ Oxidative stress markers are associated with the intensity and consequences of ischemia-reperfusion injury during deceased-donor kidney transplantation. ■ The donor’s serum hydrogen peroxide level achieved 85.7% sensitivity and a 91.7% negative predictive value for detecting delayed graft function lasting more than one week. ■ Donor H2O2 ≤14μM is suggested to dichotomize risk for delayed graft function lasting longer than a week. ■ This study provides pivotal information on the use of oxidative stress markers to identify patients at […]

Feasibility of transthoracic echocardiography in the prone position with a low-cost adaptation: morphological, functional, and hemodynamic analysis
DOI: 10.31744/einstein_journal/2026AO1802
Highlights ■ All standard echocardiographic views were obtained in the prone position. ■ In the prone position, 16 of 17 key variables were consistently acquired. ■ Image quality was slightly reduced only in the parasternal view. ■ Quantitative measurements were comparable between the prone and supine positions. ABSTRACT Objective: Transthoracic echocardiography is essential for hemodynamic assessment in critically ill patients; however, its use in the prone position remains challenging. This study aimed to assess the feasibility of performing transthoracic echocardiography […]

Prospective study of the behavior of totally implantable catheters in female oncology patients with mammary hypertrophy
DOI: 10.31744/einstein_journal/2026AO1922
Highlights ■ Mammary hypertrophy was not associated with postoperative totally implantable venous access device catheter tip displacement. ■ Upright and supine chest radiography with a radiopaque ruler allowed precise quantification of catheter tip displacement. ■ Non-deforming chest wall surgery and a history of peripherally inserted central catheters history were significantly associated with catheter tip migration. ABSTRACT Objective: This study aimed to evaluate the change in the position of totally implantable venous access devices in patients with mammary hypertrophy compared to […]

DOI: 10.31744/einstein_journal/2026AO1927
Highlights ■ High vaccine coverage correlated with sharp declines in the incidence of pediatric meningitis C. ■ The incidence fell by 98% by 2021 following national introduction of the MenC vaccine. ■ Vaccine coverage dropped after 2015, aligned with the rising cases observed in 2022. ■ MenC vaccination significantly reduced morbidity and mortality nationwide. ABSTRACT Objective: To analyze the correlation between vaccination coverage against meningitis C and epidemiological indicators of morbidity and mortality associated with the disease in Brazilian pediatric […]
