Characterization of a novel MSH2 variant in Lynch syndrome: clinical data and complementary bioinformatics assessment
DOI: 10.31744/einstein_journal/2026AO0757
Highlights ■ Family identified with recurrent colorectal cancer, suggestive of Lynch syndrome. ■ A new variant was detected, NM_000251.3(MSH2):c.1894_1898del (p.Ile633Lysfs*9). ■ The variant causes a frameshift mutation leading to a premature stop codon, suggesting pathogenicity. ■ Using bioinformatics tools, we investigated possible escape mechanisms, such as the presence of isoforms without the mutated exon. ■ Location of the variant suggests that it causes non-sense mediated decay, which is reinforced by immunohistochemistry findings showing absence of MSH2 protein expression. ■ Detailed […]

Association of the rs2814778 variant in the ACKR1 gene, responsible for the Duffy erythrocyte antigen “null” phenotype, with COVID-19 severity in Southern Brazil
DOI: 10.31744/einstein_journal/2026AO1543
Highlights ■ The rs2814778 C allele is linked to severe/critical COVID-19. ■ The association is independent of major clinical risk factors. ■ The Duffy “null” phenotype may promote lung inflammation. ■ rs12075 and rs4073 showed no association with COVID-19 severity. ABSTRACT Objective: This study aimed to analyze the possible association between rs2814778, rs12075 (ACKR1 gene), and rs4073 (CXCL8 gene) single nucleotide variants and COVID-19 severity. Methods: This cross-sectional study included 319 COVID-19 diagnosed patients at two hospitals in Paraná, Brazil […]

Predicting intensive care unit length of stay: comparing physician assessments with software predictions in a multicenter study
DOI: 10.31744/einstein_journal/2025AO1265
Highlights ■ The sample included 555 patients from three hospitals (both public and private), representing diverse care settings. ■ Physician and software predictions showed moderate correlation with observed intensive care unit length of stay, highlighting limitations in absolute prediction accuracy. ■ Categorizing length of stay into time periods (<2, 2-5, >5 days) improved prediction accuracy to approximately 60% for both physicians and Epimed Monitor Performance®. ■ Epimed Monitor Performance® identified patients at risk of prolonged intensive care unit stay with […]

Smartphone-based retrospective analysis for malaria hotspot detection
DOI: 10.31744/einstein_journal/2025AO1826
Highlights ■ Patients gave informed consent to share GPS history from their smartphones. ■ Anonymized GPS data revealed stay points and malaria infection hotspots in Manaus. ■ Hotspots guided health agents to mosquito breeding sites, aiding malaria control. ABSTRACT Objective: To leverage passively collected retrospective smartphone location data to accurately identify malaria transmission hotspots through the development of a novel tool, the Sickness Positioning System. Methods: We collected anonymized location history data from over 200 malaria-infected individuals using Google Takeout. […]

Pulmonary nodules near fissures in hepatocellular carcinoma: assessing their clinical significance
DOI: 10.31744/einstein_journal/2025AO1895
Highlights ■ Typical perifissural nodules remain radiologically stable with no metastatic potential. ■ Only two nodules progressed to metastasis (one atypical perifissural nodule and one non-perifissural nodule). ■ Atypical and non-perifissural nodules require closer follow-up. ■ Annual growth rate was a strong marker of malignancy. ABSTRACT Objective: To evaluate whether pulmonary nodules adjacent to fissures, particularly perifissural nodules detected on chest computed tomography in patients with hepatocellular carcinoma, can be reliably classified as benign based on their radiological characteristics. Methods: […]

DOI: 10.31744/einstein_journal/2025AO1182
Highlights ■ Telerehabilitation included breathing exercises and health education. ■ Health education alone was applied in the Control Group. ■ Remote sessions were conducted at home via videoconference for 8 weeks. ■ Breathing exercises improved functional capacity in patients with chronic obstructive pulmonary disease. ABSTRACT Objective: This study aimed to analyze the effects of two proposed telerehabilitation interventions on the functional capacity of patients with chronic obstructive pulmonary disease. Methods: A randomized clinical trial was conducted with 60 patients of […]

Artificial intelligence in a Brazilian lung cancer screening program: accuracy and predictive values
DOI: 10.31744/einstein_journal/2025AO1283
Highlights ■ The artificial intelligence tool demonstrated high sensitivity (92.5%) and a negative predictive value of 97.8%. This effectively excluded examinations that were not clinically significant. ■ However, its low specificity (78.5%) and positive predictive value (50%) emphasize the importance of radiologist’s supervision. ■ – artificial intelligence missed 4.7% of nodules measuring >6mm, most of which were subsolid (62%). ■ The tool has the potential to improve workflows in lung cancer screening programs. ABSTRACT Objective: We aimed to investigate the […]
