Peripheral blood cells, such as platelets or lymphocytes, have been studied in the investigation of systemic derangements and central nervous system biochemical changes occurring in several neuropsychiatric disorders. In the present work, assaying platelet and lymphocyte peripheral-type benzodiazepine binding in patients with Alzheimer's disease (AD) and healthy controls, we found a significantly reduced number of cell receptors in patients' platelets and lymphocytes. These results are discussed with reference to central nervous system biochemical abnormalities in AD. Moreover, the lymphocyte binding data may represent an impairment of the immune response in AD, since lymphocyte surface peripheral-type benzodiazepine receptors seem to be related to immune function.

Evidence-based Medicine and Clinical Epidemiology Center, Army Medical University (Third Military Medical University), PR China. Electronic address:
Background: This study aimed to assess the predictive value of 7 routinely available inflammation biomarkers for stroke and all-cause mortality in 229 non-valvular AF patients.
Methods And Results: C-reactive protein, Albumin (ALB), d-dimer, fibrinogen, the number of platelets, lymphocytes, monocyte and neutrophils were measured. The Multivariable Cox proportional hazard model was used to assess the predictive value of the inflammation biomarkers for stroke and all-cause mortality, the c-statistic, Net Reclassification Improvement (NRI), and Integrated Discrimination Improvement (IDI) were calculated.
Preoperative SII Can Predict Postoperative Recurrence and Serious Complications in Patients with Hepatolithiasis.

Purpose: The occurrence and progression of hepatolithiasis are related to inflammatory reactions and immune proteins. This study aims to evaluate the relationship between systemic immune index (SII) in recurrence-free survival (RFS), as well as the incidence of severe postoperative complications in hepatolithiasis patients.
Patients And Methods: We retrospectively analyzed 177 patients with hepatolithiasis.
Pan-immune inflammation value and systemic inflammatory index as a measure of systemic inflammation in patients with psoriasis: A retrospective study.

Psoriasis is a chronic immune-mediated disease characterized by systemic inflammation. In recent years, the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and pan-immune-inflammation value (PIV) were shown to be important indicators of inflammation. The aim of the present study is to investigate NLR, PLR, SII, SIRI, PIV together in patients with psoriasis.

Recently, immature granulocyte count (IGC) in an automated blood cell counter was introduced as a new inflammatory marker. We aimed to evaluate the relationship between the IGC and percentage of immature granulocyte (IG%) and disease activity in patients with pemphigus. Pemphigus disease area index (PDAI), IGC, IG%, C-reactive protein, neutrophil/lymphocyte ratios, platelet-to-lymphocyte ratio (PLR), anti-desmoglein 1, and anti-desmoglein 3 levels in patients with pemphigus were recorded retrospectively, and the statistical relationship between them was evaluated.

Preoperative delirium is common and associated with poor clinical outcomes in elderly hip fracture patients. Although inflammatory markers have shown potential in predicting postoperative delirium, their relevance to preoperative delirium remains unclear. This study aimed to investigate the relationship between inflammatory markers and preoperative delirium to improve risk prediction and management strategies.
