Article Abstract
Aim And Background: Neutrophil CD64 (nCD64) is evolving as a prognostic biomarker in sepsis. The primary objective of this study was to evaluate whether serial trend of nCD64, procalcitonin (PCT), and C-reactive protein (CRP) predict 28-day mortality in patients with sepsis/septic shock, as per Sepsis-3 criteria.
Materials And Methods: This prospective, observational single-center cohort study included 60 adult patients (age ≥18 years) with sepsis. Serial biomarker levels with SOFA score were measured at admission (day 0), on day 4, and on day 8.
Results: Of the 60 patients, 42 (70%) had septic shock. Biomarker levels at admission did not differ between patients with sepsis and septic shock. Thirty-seven patients survived and 23 were non-survivors by day 28. There was a significant fall in serial trend of all three biomarkers from admission till day 8 (Friedman < 0.001) in survivors compared to a non-significant change in non-survivors. On multivariate analysis, SOFA score at admission (OR 1.731), more days with vasopressor support (OR 1.077), rise in CD64 from day 0 to day 8 (OR 1.074), and rise in CRP from day 0 to 8 (OR 1.245) were the significant predictors of 28-day mortality ( < 0.05). The highest area under the ROC curve was obtained for more days of vasopressor therapy (0.857), followed by a rise in CD64 from day 0 to day 8 (0.798).
Conclusion: Serial trend of biomarkers has prognostic utility. The rise in CD64 from day 0 to day 8 was a good predictor of mortality compared to the trend of other biomarkers.

Background Increased intracranial pressure (ICP) can be reliably detected at the bedside using the optic nerve sheath diameter (ONSD). The functional outcome in stroke patients can be predicted with the use of acute-phase ONSD dynamics. Objectives To determine the predictive accuracy of ONSD on days 0, one, and three for the prognosis of ischemic stroke patients presented to emergency medicine as measured by Modified Rankin Scale (mRS) score.

Background: Between November 2023 and March 2024, coastal Kenya experienced another wave of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections detected through our continued genomic surveillance. Herein, we report the clinical and genomic epidemiology of SARS-CoV-2 infections from 179 individuals (a total of 185 positive samples) residing in the Kilifi Health and Demographic Surveillance System (KHDSS) area (~ 900 km).
Methods: We analyzed genetic, clinical, and epidemiological data from SARS-CoV-2 positive cases across pediatric inpatient, health facility outpatient, and homestead community surveillance platforms.

Hepatitis B virus (HBV) infection remains a major global health burden. While interferon-alpha (IFNα) therapy demonstrates antiviral and immunomodulatory effects, reliable prognostic markers for sustained response are needed. Transaminases, hematological parameters, and cytokines may serve as potential predictors, but their dynamic changes during IFNα therapy remain poorly characterized.

Objective: Digital Rectal Examination (DRE) remains an important preventive measure in primary care settings, but a single screening may produce false positives. We sought to explore the trend of abnormal DRE (suspicious and non-suspicious) findings in men with and without prostate cancer.
Methods: We utilized data on 34,756 men (1,713 Black and 33,043 White) from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial.
