Effects of perinatal HIV-infection on the cortical thickness and subcortical gray matter volumes in young adulthood.

Medicine (Baltimore) 2021 Apr;100(15):e25403

Paediatric Infectious Diseases Department, Hospital Universitario 12 De Octubre, Madrid, Madrid, Spain.

Abstract: Brain atrophy has been observed in perinatally HIV-infected patients (PHIV) despite initiation on combined antiretroviral treatment (cART), but neuroimaging studies are limited. We aimed to evaluate cortical thickness (CT) and subcortical gray matter (GM) volumes of PHIV youths with stable immunovirological situation and with a normal daily performance.A prospective cross-sectional study was conducted.

Sapropterin (BH4) Aggravates Autoimmune Encephalomyelitis in Mice.

Neurotherapeutics 2021 Apr 12. Epub 2021 Apr 12.

Institute of Clinical Pharmacology, Medical Faculty, Goethe-University, Frankfurt, Germany.

Depletion of the enzyme cofactor, tetrahydrobiopterin (BH4), in T-cells was shown to prevent their proliferation upon receptor stimulation in models of allergic inflammation in mice, suggesting that BH4 drives autoimmunity. Hence, the clinically available BH4 drug (sapropterin) might increase the risk of autoimmune diseases. The present study assessed the implications for multiple sclerosis (MS) as an exemplary CNS autoimmune disease. Read More

Toxoplasmosis in Pediatric Hematopoietic Stem Cell Transplantation Patients.

Transplant Cell Ther 2021 Apr 10;27(4):292-300. Epub 2020 Dec 10.

Lucile Packard Children's Hospital Stanford, Palo Alto, California; Division of Infectious Diseases, Department of Pediatrics, Stanford University School of Medicine, Stanford, California; Dr Jack S. Remington Laboratory for Specialty Diagnostics, Palo Alto Medical Foundation, Palo Alto, California.

Infection due to the protozoa Toxoplasma gondii can be life-threatening in hematopoietic stem cell transplantation (HSCT) recipients. Most cases of toxoplasmosis in HSCT recipients result from reactivation of latent infection in individuals who were Toxoplasma-seropositive before transplantation and did not receive appropriate prophylaxis. Pretransplantation screening with Toxoplasma IgG and IgM antibodies is suggested for all allogeneic HSCT recipients and their donors and all autologous HSCT recipients. Read More

THE IMPACT OF NEUTROPHIL-TOLYMPHOCYTE RATIO AND PLATELETTO- LYMPHOCYTE RATIO IN CAROTID ARTERY DISEASE.

Rev Port Cir Cardiotorac Vasc 2021 Apr 8;28(1):45-51. Epub 2021 Apr 8.

Department of Angiology and Vascular Surgery, Centro Hospitalar Universitário de São João, Porto, Portugal.

Introduction: Inflammation is a common underlying feature of atherosclerosis. Several inflammatory biomarkers have been reported to have prognostic value, in several areas, including in vascular surgery. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) may permit to identify patients at greater risk for cerebrovascular events, tailor patient management, improve preoperative status and possibly develop target anti-atherosclerotic therapy.

Carbon-ion radiotherapy subsequent to balloon-occluded retrograde transvenous obliteration for hepatocellular carcinoma with hepatic encephalopathy: a multidisciplinary approach.

Clin J Gastroenterol 2021 Apr 3. Epub 2021 Apr 3.

Department of Radiation Oncology, Gunma University Graduate School of Medicine, 3-39-22, Showa-machi, Maebashi, Gunma, 371-8511, Japan.

Radical treatments of hepatocellular carcinoma (HCC) with hepatic encephalopathy (HE) can be often difficult due to poor liver function or disturbance of consciousness. An effective treatment requires a combinatorial approach incorporating a treatment for HE and radical therapy for HCC that does not compromise liver function. Here, we report a case of a 78-year-old Japanese male with HCC and HE caused by splenorenal shunt. Read More

Long-Chain Acylcarnitines and Monounsaturated Fatty Acids Discriminate Heart Failure Patients According to Pulmonary Hypertension Status.

Metabolites 2021 Mar 26;11(4). Epub 2021 Mar 26.

Research Center, Montreal Heart Institute, Montréal, QC H1T1C8, Canada.

Defects in fatty acid (FA) utilization have been well described in group 1 pulmonary hypertension (PH) and in heart failure (HF), yet poorly studied in group 2 PH. This study was to assess whether the metabolomic profile of patients with pulmonary hypertension (PH) due HF, classified as group 2 PH, differs from those without PH. We conducted a proof-of-principle cross-sectional analysis of 60 patients with chronic HF with reduced ejection fraction and 72 healthy controls in which the circulating level of 71 energy-related metabolites was measured using various methods.

Vitamin D Deficiency Induces Chronic Pain and Microglial Phenotypic Changes in Mice.

Int J Mol Sci 2021 Mar 30;22(7). Epub 2021 Mar 30.

Department of Experimental Medicine, Università degli Studi della Campania "Luigi Vanvitelli", 80138 Naples, Italy.

The bioactive form of vitamin D, 1,25-dihydroxyvitamin D (1,25D3), exerts immunomodulatory actions resulting in neuroprotective effects potentially useful against neurodegenerative and autoimmune diseases. In fact, vitamin D deficiency status has been correlated with painful manifestations associated with different pathological conditions. In this study, we have investigated the effects of vitamin D deficiency on microglia cells, as they represent the main immune cells responsible for early defense at central nervous system (CNS), including chronic pain states.

New Avenues for Parkinson's Disease Therapeutics: Disease-Modifying Strategies Based on the Gut Microbiota.

Biomolecules 2021 Mar 15;11(3). Epub 2021 Mar 15.

Neurodegenerative Diseases Research Group, Vall d'Hebron Research Institute (VHIR)-Center for Networked Biomedical Research on Neurodegenerative Diseases (CIBERNED), Passeig Vall d'Hebron 119-129, 08035 Barcelona, Spain.

Parkinson's disease (PD) is a multifactorial neurodegenerative disorder that currently affects 1% of the population over the age of 60 years, and for which no disease-modifying treatments exist. Neurodegeneration and neuropathology in different brain areas are manifested as both motor and non-motor symptoms in patients. Recent interest in the gut-brain axis has led to increasing research into the gut microbiota changes in PD patients and their impact on disease pathophysiology. Read More

The Interplay between Immune System and Microbiota in Inflammatory Bowel Disease: A Narrative Review.

Int J Mol Sci 2021 Mar 17;22(6). Epub 2021 Mar 17.

Gastroenterology Unit, Hospital Universitario de La Princesa, Instituto de Investigación Sanitaria Princesa (IIS-IP), Universidad Autónoma de Madrid (UAM), 28006 Madrid, Spain.

The importance of the gut microbiota in human health is currently well established. It contributes to many vital functions such as development of the host immune system, digestion and metabolism, barrier against pathogens or brain-gut communication. Microbial colonization occurs during infancy in parallel with maturation of the host immune system; therefore, an adequate cross-talk between these processes is essential to generating tolerance to gut microbiota early in life, which is crucial to prevent allergic and immune-mediated diseases.
