Cytochemical methods were used to explore the changes in the activity of redox (succinate dehydrogenase, mitochondrial alpha-glycerophosphate dehydrogenase) and hydrolytic (acid, alkaline phosphatase, myeloperoxidase) enzymes of peripheral blood leukocytes of random-bred albino rats during simulation of toxic hepato-, nephropathy and hemic hypoxia of different gravity. The studies of the changes of leukocyte distribution according to the activity of the above enzymes were demonstrated to be informative for the diagnosis of prepathological conditions. The possibility was also shown of differentiating the gravity of the pathological conditions with the aid of an analysis of the enzymes under study by the method of linear discriminant functions.

Background: Due to the heterogeneity of literature findings, stent type selection for the endovascular treatment of complex aorto-iliac occlusive disease remains challenging. The BELSTREAM study, a physician-initiated, prospective, multicenter, single-arm study, aims to report the safety and efficacy of the balloon expandable LifeStream Peripheral Stent Graft System (BD, Tempe, Arizona, USA) for the treatment of complex TASC C and D aorto-iliac artery lesions.
Methods: Seventy patients and 133 lesions were included at six Belgian institutions.

Purpose: To investigate the prognostic value of inflammatory indexes based on peripheral blood cells in unresectable hepatocellular carcinoma (HCC) patients treated with Lenvatinib combined with PD-1 inhibitors.
Methods: This study retrospectively collected baseline inflammatory indexes from HCC patients received Lenvatinib and PD-1 inhibitor-based combination therapy at the Cancer Hospital of the Chinese Academy of Medical Sciences between October 2018 and October 2021. The optimal threshold values for inflammatory indexes determined using X-tile.

Major Depressive Disorder (MDD) is a widespread psychiatric condition impacting social and occupational functioning, making it a leading cause of disability. The diagnosis of MDD remains clinical, based on the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria, as biomarkers have not yet been validated for diagnostic purposes or as predictors of treatment response. Traditional treatment strategies often follow a one-size-fits-all approach obtaining suboptimal outcomes for many patients who fail to experience response or recovery.

Skews in the neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) increasingly demonstrate prognostic capability in a range of acute and chronic mental health conditions. There has been a recent uptick in structural and functional magnetic responance imaging data corroborating the role of NLR and MLR in a cluster of neuropsychiatric disorders that are characterized by cognitive, affective, and psychomotor dysfunction. Moreover, these deficits are mostly evident in setting of acute and chronic disease comorbidity implicating aging and immunosenescent processes in the manifestation of these geriatric syndromes.
