Neurological complications of hepatitis C infections.
Abstract Chronic hepatitis C virus (HCV) infection is a highly prevalent systemic disease, which can cause a variety of neurological complications. The HCV-associated symptoms can be differentiated into central and peripheral nervous systems as well as the musculature. Important pathomechanisms are HCV-associated autoimmunity (e.g. mixed cryoglobulinemia with polyneuropathy) and direct neurotoxic effects of the virus (e.g. HCV-associated cognitive deficits). Distal symmetric polyneuropathies, small fiber neuropathies and cognitive deficits are the most prevalent neurological manifestations. Furthermore, HCV infe...

Optimal neuro-fuzzy control of hepatitis C virus integrated by genetic algorithm
Hepatitis C blood born virus is a major cause of liver disease that more than three per cent of people in the world is dealing with, and the spread of hepatitis C virus (HCV) infection in different populations is one of the most important issues in epidemiology. In the present study, a new intelligent controller is developed and tested to control the hepatitis C infection in the population which the authors refer to as an optimal adaptive neuro-fuzzy controller. To design the controller, some data is required for training the employed adaptive neuro-fuzzy inference system (ANFIS) which is selected by the genetic algorithm....

Elevation of the ACTH/cortisol ratio in female opioid dependent patients: A biomarker of aging and correlate of metabolic and immune activation.
CONCLUSIONS: These data establish the ACTH/cortisol ratio as a negative biomarker of aging in females, and show that this decline is more pronounced in ODP an effect which is partly related to HCV seropositivity, immune and metabolic factors. Dementias are one of the most serious health and socioeconomic issues. Multi-infarct dementia (MID) and Alzheimer´s type dementia (AD) exhibit differences in cerebrovascular blood flow velocity profiles and in presence of microemboli, detected by transcranial Doppler sonography.

Targeting cytokines in reduction of depressive symptoms: A comprehensive review
The objectives of the current narrative review are to critically evaluate the literature about the effects of cytokine blockers on clinical outcomes in MDD and in the reduction of depressive symptom severity in individuals using these medications primarily to treat inflammatory conditions. A small number of clinical trials assessing the effects of cytokine blockers for depression and depressive symptoms have been completed. These trials suggest that in individuals with immune dysfunction (e.g. elevated pro-inflammatory cytokine levels), cytokine blockers may allow for improved clinical outcomes in MDD that would not be ach...

SemEHR: A general-purpose semantic search system to surface semantic data from clinical notes for tailored care, trial recruitment, and clinical research*
ConclusionResults from the multiple case studies demonstrate SemEHR ’s efficiency: weeks or months of work can be done within hours or minutes in some cases. SemEHR provides a more comprehensive view of patients, bringing in more and unexpected insight compared to study-oriented bespoke IE systems. SemEHR is open source, available athttps://github.com/CogStack/SemEHR.

Active search for hepatitis C patients in Primary Care
CONCLUSIONS: Active search for patients with hepatitis C in PC together with the OSD are effective measures to detect hidden infections and to increase the number of treatments, contributing to the elimination of hepatitis C.PMID:34284593 | DOI:10.17235/reed.2021.8067/2021

Next-Generation Sequencing of 5' Untranslated Region of Hepatitis C Virus in Search of Minor Viral Variant in a Patient Who Revealed New Genotype While on Antiviral Treatment.
In conclusion, longitudinal analysis of HCV variants, employing two independent deep sequencing methods, suggests that the transient presence of a different genotype strain in PBMC was a result of superinfection and not a selection of pre-existing minor variant.

Hepatitis C point-of-care diagnostics: in search of a single visit diagnosis.
Authors: Grebely J, Applegate TL, Cunningham P, Feld JJ Abstract INTRODUCTION: The availability of simple, tolerable, therapies for hepatitis C virus (HCV) infection with responses >95% is one of the greatest medical advances in decades, offering an opportunity to reverse the rising burden due to HCV and strive towards HCV elimination. A key challenge moving forward will be to ensure that those who are undiagnosed are made aware of their infection, receive HCV therapy and achieve viral cure. The availability of point-of-care tests for HCV infection has the potential to simplify testing algorithms, increase diagn...

An update on recent developments in the search for hepatitis C virus therapies with pan-genotypic efficacy.
Authors: Borgia G, Scotto R, Buonomo AR Abstract INTRODUCTION: Pangenotypic drugs against HCV infections led to high rates of virologic response with very limited adverse events. Moreover, they are easy to administer among all HCV genotypes with minimal changes in treatment schedule. For this reason, the demand for new antivirals is greatly lowered. Areas covered. We discuss results from trials assessing safety and efficacy of Ravidasvir, which is the only direct-acting antiviral currently in clinical development. Expert opinion. The currently available pangenotypic drug combinations are very effective in HCV eradi...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Orbitocerebral Mucormycosis in a Patient With Central Nervous System Lymphoma
A 61-year-old man with well-controlled diabetes mellitus type 2, cirrhosis from hepatitis C, alcohol abuse, and portal hypertension presented with painful vision loss and left orbital swelling. Imaging showed diffuse orbital, perineural, and pachymeningeal inflammation. He was initially diagnosed with neurosarcoidosis. However, cerebrospinal fluid analysis revealed central nervous system lymphoma, and lacrimal gland biopsy showed fungal organisms consistent with mucormycosis. The authors describe a case of Mucorales infection lacking sinonasal involvement and discuss the differential diagnosis and management of patients pr...
