Objectives: To calculate and assess the role of neutrophil-to-lymphocyte ratio (NLR) and mean platelet volume (MPV)/ platelet count (PLT) ratios and their trends as prognostic indicators in neonates and children with sepsis.
Methods: This prospective observational study was planned over a period of two years at a tertiary care teaching hospital. Two hundred seventy children with clinical suspicion of or diagnosed as sepsis were enrolled. Serial hemograms (day 1, 4, 7, 10) and trends of NLR and MPV/PLT ratios were reviewed.
Results: NLR on day 10 of hospital stay had maximum sensitivity of 65% and specificity of 62%. Day 1 MPV was significantly higher in the mortality group. There was a significant correlation between lower Pediatric Sequential Organ Failure Assessment (p-SOFA) score and MPV in the survival group. MPV/PLT ratio on day 7 had maximum sensitivity of 85% and specificity of 74% in prediction of mortality. Serial decreasing trend of NLR (2.88-1.16) and MPV/PLT from day 1 to 10 (8.58-8.48) were associated with improved outcome (p < 0.001).
Conclusions: High NLR, MPV and MPV/PLT on admission are associated with increased mortality in neonatal and pediatric sepsis. Serial decreasing trends in NLR, MPV and MPV/PLT ratio are associated with improved prognosis.

Granulocyte and Monocyte Adsorption Therapy in Patients With Sepsis: A Feasibility Study.

Laboratory for Immune Response and Regulatory Medicine, Fujita Health University School of Medicine, Toyoake, Japan.
Background: The pathogenesis of sepsis is thought to be linked to a dysregulated immune response, particularly that involving neutrophils. We have developed a granulocyte adsorption column as a "decoy organ," which relocates the massive inflammation in organs in the body to a blood purification column. This study was conducted to assess the safety and experimental effectiveness of granulocyte monocyte adsorption apheresis-direct hemoperfusion (G1-DHP) in the treatment of patients with sepsis, using a prospective, multicenter design.

Shenzhen Center for Chronic Disease Control, No. 2021 Buxin Road, Luohu District, Shenzhen, 518020, China.
Background: Serum vitamin D deficiency is intricately linked to metabolic disorders, however, evidence on its association with continuous metabolic risk in children and adolescents remains insufficient. This study aims to elucidate the relationship between serum vitamin D levels and continuous metabolic risk.
Methods: The cross-sectional analysis involved 4490 participants aged 6 ~ 18, and the longitudinal investigation included 1398 individuals aged 6 ~ 12 years.
The effects of intermittent fasting on antioxidant and inflammatory markers and liver enzymes in postmenopausal, overweight and obese women with rheumatoid arthritis: a randomized controlled trial.

Rheumatoid arthritis (RA) is a chronic inflammatory disorder affecting postmenopausal women. This study investigated the effects of intermittent fasting (IF) on antioxidant and inflammatory markers and liver enzymes in postmenopausal, overweight and obese women with RA. This 8-week randomized controlled trial included 44 postmenopausal women with RA divided into an intervention group following a 16:8 IF diet and a control group maintaining their usual diet and received recommendations for healthy eating.
