Prognostic utility of biomarker levels and clinical severity scoring in sepsis: a comparative study.
Procalcitonin (PCT) is one of the best validated biomarkers in the management of sepsis. However, its prognostic utility remains poorly studied. The present study sought to assess the prognostic utility of serial PCT assessments in patients with sepsis, and to compare the prognostic predictive capability of serial measurements of PCT with conventional markers of inflammation and validated intensive care unit (ICU) severity scoring systems. ⋯ PCT clearance on days 3 and 5 of admission was measured and demonstrated predictive accuracy comparable to day-matched APACHE IV scores. While serial levels of serum PCT in patients with sepsis are accurate in the prediction of adverse patient outcome, they do not offer any additional clinical benefit over existing severity of illness scores and may be cost prohibitive in resource-limited settings.

This study aims to identify possible genes associated with esophageal squamous cell carcinoma (ESCC) by bioinformatics tool and further explore the function of immunoglobulin heavy chain variable family 4 gene (IGHV4)-28 in the ESCC progression. The ESCC-related genes in Cancer Genome Atlas (TCGA) database were analyzed by bioinformatics tools, which finally identified IGHV4-28. The expression levels of IGHV4-28 in TE-4 and EC9706 cells were detected by quantitative reverse transcription-PCR (qRT-PCR). ⋯ IGHV4-28 was highly expressed in TE-4 and EC9706 cell lines and overexpression of IGHV4-28 enhanced cell proliferation, invasion, and migration, as well as decreased apoptosis rate. Moreover, nude mice transplanted with IGHV4-28-silencing TE-4 cells showed restrained tumor weight and volume. In summary, IGHV4-28 was increasingly expressed in ESCC and may serve as a therapeutic target in the treatment of ESCC.

Natriuretic peptide levels are elevated in persons with chronic kidney disease (CKD) stages 1-3, but it remains unclear whether this is associated with extracellular volume excess or early cardiovascular changes. We hypothesized that patients with CKD stages 1-3 would have evidence of cardiovascular changes, which would associate with brain natriuretic peptide (BNP), amino-terminal-pro-BNP (NT-pro-BNP), and patient-reported symptoms. Outpatients with CKD stages 1-3 and non-CKD controls were enrolled. ⋯ TPRI and blood pressure correlated moderately with symptoms. Elevated natriuretic peptides may coincide with low cardiac index and elevated peripheral resistance in patients with CKD stages 1-3. The role of these biomarkers to detect subclinical cardiovascular changes needs to be further explored.

Family history of coronary artery disease (FHxCAD) is a critical risk factor for CAD, underscoring the contribution of genetic factors to disease pathogenesis and susceptibility. Takotsubo cardiomyopathy (TCM) simulates the clinical features of and frequently coexists with CAD. However, the association between FHxCAD and TCM is unclear. ⋯ TCM with FHxCAD patients had a reduced incidence of cardiogenic shock, acute kidney injury (AKI), and acute respiratory failure (ARF); lower mortality rates; shorter length of stay (LOS); and decreased total charge compared with TCM without FHxCAD patients (p<0.05). In the matched cohort, TCM with FHxCAD patients (vs TCM without FHxCAD patients) had a lower incidence of cardiogenic shock (2.2% vs 6.3%, p<0.001; OR 0.33, 95% CI 0.18 to 0.61), AKI (5.1% vs 8.7%, p=0.016; OR 0.57, 95% CI 0.36 to 0.88), and ARF (5.7% vs 12.7%, p<0.001; OR 0.42, 95% CI 0.28 to 0.63); decreased in-hospital mortality (<11% vs 3.1%, p=0.002; OR 0.2, 95% CI 0.07 to 0.57); shorter LOS (2.66±1.96 days vs 3.40±3.05 days, p<0.001); and a reduced total charge (p=0.001), respectively. FHxCAD was associated with favorable outcomes in both unmatched and propensity-matched cohorts.
