As the COVID-19 pandemic continues, countries still have to struggle with their endemic diseases such as Crimean-Congo hemorrhagic fever (CCHF). Severity grading score (SGS) is a practical approach and may shed light on the course of the CCHF, whose pathogenesis is not clearly understood, and have no effective treatments. It is aimed to assess the association between SGS and acute phase reactants (APR). Laboratory-confirmed patients were categorized by severity scores, and the relationship between APR and SGS was evaluated. A significant correlation between SGS and C-reactive protein (CRP) was found (p less then 0.001). High SGS was associated with mortality and high CRP levels were used to predict the mortality at the beginning of the hospital admission. To predict the outcome of the disease and for appropriate patient management, SGS and APR can be used simultaneously.The main active metabolite of vitamin D, the 1,25-dihydroxyvitamin D (1,25(OH)2D), and the shed form of the α-Klotho gene (S-Klotho) play an important role in aging-related physiological processes and are currently considered powerful antiaging renal biomarkers. We aimed to investigate the relationship between 1,25(OH)2D and S-Klotho plasma levels in middle-aged sedentary healthy adults. We also aimed to study the mediation role of body composition, physical activity levels, dietary parameters, and blood markers in the association between 1,25(OH)2D and S-Klotho plasma levels. A total of 73 middle-aged sedentary adults (53.4% women; 53.7 ± 5.1 years old) were enrolled in this cross-sectional study. The 1,25(OH)2D plasma levels were measured using a DiaSorin Liaison® immunochemiluminometric analyzer. DNA Methyltransferase inhibitor S-Klotho plasma levels were measured using a solid-phase sandwich enzyme-linked immunosorbent assay. Body composition analysis was performed using dual-energy X-ray absorptiometry scanner. A tendency toward a negative association was observed between 1,25(OH)2D and S-Klotho plasma levels (β = -0.222, R2 = 0.049, p = 0.059). The association was attenuated after controlling for age and sex and become significant after controlling for fat mass index. In addition, the association between 1,25(OH)2D and S-Klotho levels was indirectly influenced by bone mineral density (BMD), with a percentage of mediation of 31.40%. Our study shows that 1,25(OH)2D is negatively associated with S-Klotho plasma levels in middle-aged sedentary adults, which is partially mediated by BMD.

Although neuroimaging is a primary diagnostic tool in the clinical assessment of TBI, our understanding of how specific neuroimaging findings relate to outcome remains limited. Our study aims to identify imaging biomarkers of long-term neurocognitive outcome after severe adolescent TBI. Twenty-four adolescents with severe TBI (Glasgow Coma Scale ≤8) enrolled in the ADAPT (Approaches and Decisions after Pediatric TBI) study were recruited for magnetic resonance imaging (MRI) scanning 1-2 years post-injury at 13 participating sites. Subjects underwent outcome assessments ∼1-year post-injury, including the Wechsler Abbreviated Scale of Intelligence (IQ) and the Pediatric Glasgow Outcome Scale-Extended (GOSE-Peds). A typically developing control cohort of 38 age-matched adolescents also underwent scanning and neurocognitive assessment. Brain-image segmentation was performpectively.Inflammaging is associated with aging-associated cognitive loss and neurodegeneration. Chronic nonsteroidal anti-inflammatory drug (NSAID) use has been reported to reduce the incidence of Alzheimer's disease (AD), presumably by inhibiting inflammation, although NSAIDs appear to not be good candidates for anti-AD therapeutics given disappointing clinical trial results. Prostaglandin E2 (PGE2) acts downstream of NSAID target COX-2, a cyclooxygenase, to activate several G-protein coupled receptors (GPCRs) including EP2, which is now reported to reduce glycolysis and oxidative phosphorylation during aging by increasing glycogen synthesis and polarizing myeloid cells toward the M1 proinflammatory phenotype. Inhibiting EP2 using small molecule drugs polarizes macrophages toward the anti-inflammatory phenotype, restores youthful metabolism and mitochondrial morphology as well as youthful hippocampus-based memory capability. EP2 may be a better target than COXs for the development of drugs that improve age-associated mild cognitive impairment and possibly even for the development of drugs to treat dementias.Obesity is a major risk factor for cardiovascular disease. Blood-detected epigenetic profiles may serve as non-invasive clinically relevant biomarkers. Therefore, we investigated DNA methylation of genes involved in inflammation in peripheral blood of obese subjects and lean controls and their correlation with cardiometabolic measurements. We obtained blood and adipose tissue (AT) samples from bariatric patients (n = 24) and control adults (n = 24). AT-isolated arterioles were tested for flow-induced dilation (FID) and production of nitric oxide (NO) and reactive oxygen species (ROS). Brachial artery flow-mediated dilation (FMD) was measured via doppler ultrasound. Promoter methylation of 94 genes involved in inflammation and autoimmunity were analysed in whole-blood DNA in relation to vascular function and cardiometabolic risk factors. 77 genes had ahigher methylated fraction in the controls compare obese subjects and 28 proinflammatory genes were significantly hypomethylated in the obese individuals; on top of these genes are CXCL1, CXCL12, CXCL6, IGF2BP2, HDAC4, IL12A, and IL17RA. Fifteen of these genes had significantly higher mRNA in obese subjects compared to controls; on top of these genes are CXCL6, TLR5, IL6ST, EGR1, IL15RA, and HDAC4. Methylation % inversely correlated with BMI, total fat %, visceral fat%, blood pressure, fasting plasma insulin, serum IL6 and C-reactive protein, arteriolar ROS, and alcohol consumption and positive correlations with lean %, HDL, plasma folate and vitamin B12, arteriolar FID and NO production, and brachial FMD. Our results suggest that vascular dysfunction in obese adults may be attributed to asystemic hypomethylation and over expression of the immune-related genes.
