Double Positive CD4CD8 (DP) T-Cells Display Distinct Exhaustion Phenotype in Chronic Hepatitis C.

In chronic hepatitis C (CHC), characterized by exhaustion of T-cell function, increased frequencies of double-positive (DP) (CD4CD8) cells are present in peripheral blood. We compared the exhaustion phenotype between DP and single positive (SP) T-cells, including HCV-specific cells, and assessed the effect of successful HCV treatment on inhibitory receptors expression. Blood samples from 97 CHC patients were collected before and six months post-treatment.

Cardiovascular disease/stroke risk stratification in deep learning framework: a review.

The global mortality rate is known to be the highest due to cardiovascular disease (CVD). Thus, preventive, and early CVD risk identification in a non-invasive manner is vital as healthcare cost is increasing day by day. Conventional methods for risk prediction of CVD lack robustness due to the non-linear relationship between risk factors and cardiovascular events in multi-ethnic cohorts.

Comparison of C-reactive protein with distinct hyperinflammatory biomarkers in association with COVID-19 severity, mortality and SARS-CoV-2 variants.

C-reactive protein (CRP) has been one of the most investigated inflammatory-biomarkers during the ongoing COVID-19 pandemics caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The severe outcome among patients with SARS-CoV-2 infection is closely related to the cytokine storm and the hyperinflammation responsible for the acute respiratory distress syndrome and multiple organ failure. It still remains a challenge to determine which of the hyperinflammatory biomarkers and cytokines are the best predictors for disease severity and mortality in COVID-19 patients.

Proteomic Investigation of COVID-19 Severity During the Tsunamic Second Wave in Mumbai.

Maharashtra was severely affected during the noxious second wave of COVID-19, with the highest number of cases recorded across India. The emergence of new symptoms and dysregulation of multiple organs resulted in high disease severity during the second wave which led to increased difficulties in understanding the molecular mechanisms behind the disease pathology. Exploring the underlying factors can help to relieve the burden on the medical communities to some extent by prioritizing the patients and, at the same time, opening avenues for improved treatments.

TGF Beta as a Prognostic Biomarker of COVID-19 Severity in Patients with NAFLD-A Prospective Case-Control Study.

Non-alcoholic fatty liver disease (NAFLD), the leading cause of chronic liver disease in Western countries, has been identified as a possible risk factor for COVID-19 severity. However, the immunological mechanisms by which NAFLD exacerbates COVID-19 remain unknown. Transforming growth factor-beta 1 (TGF-β1) has an important immunomodulatory and pro-fibrotic role, which has already been described in NAFLD.

Association of Gut and Chronic Spontaneous Urticaria.

(1) Background: Chronic spontaneous urticaria (CSU) has been linked to the dysbiosis of the gut microbiota. Furthermore, various studies have highlighted the anti-inflammatory properties of short-chain fatty acids (SCFAs), whose production is primarily regulated by the gut microbiota. However, only a few studies have investigated the role of major SCFA producers, such as , in skin inflammatory diseases.

The clinical course of herpes zoster is similar in immunocompetent and immunocompromised paediatric patients.

Aim: We aimed to compare the clinical manifestation of HZ in immunocompetent and immunocompromised children.

Methods: Medical charts of all consecutive children hospitalized and/or consulted in the Regional Hospital for Infectious Diseases in Warsaw due to HZ were retrospectively analysed. Age, history of varicella, time interval between varicella and HZ, underlying diseases, immunosuppresive therapy, dermatome involvement and HZ complications were analyzed in both groups.

Increased risk of brucellosis misdiagnosis in regions that lose their endemicity.

Over the last decades, the epidemiology of human brucellosis globally has been subjected to significant changes, with the eradication of many existing endemic hot spots. This paper describes three cases with initial misdiagnosis of brucellosis that were managed during 2011-2017 in Republic of North Macedonia, country that until recently has been declared as endemic region. In spite of the fever, constitutional symptoms, focal disease (spondylitis, pneumonia and orchitis) and previous contact with domestic animals, brucellosis was not initially recognized, and patients were inadequately managed.

Ability of presepsin concentrations to predict mortality in adult patients with sepsis.

Background: Early diagnosis of sepsis is essential for a favorable disease outcome. The aim of this study was to evaluate the association of initial and subsequent presepsin concentrations with sepsis outcomes.

Methods: One hundred sepsis patients were enrolled in the study from two different university centers.

Prediction of unfavorable outcomes in community-acquired bacteremia by SIRS, SOFA and qSOFA scores.

Background: Sepsis diagnostic and prognostic scoring systems have changed over time. It remains uncertain which scoring system is the best predictor of unfavorable outcomes. We aimed to evaluate prediction of community-acquired bacteremia (CAB) outcomes using on-admission systemic inflammatory response syndrome (SIRS), sequential organ failure assessment (SOFA) and quick sequential organ failure assessment (qSOFA).

Ensemble Deep Learning Derived from Transfer Learning for Classification of COVID-19 Patients on Hybrid Deep-Learning-Based Lung Segmentation: A Data Augmentation and Balancing Framework.

Background And Motivation: Lung computed tomography (CT) techniques are high-resolution and are well adopted in the intensive care unit (ICU) for COVID-19 disease control classification. Most artificial intelligence (AI) systems do not undergo generalization and are typically overfitted. Such trained AI systems are not practical for clinical settings and therefore do not give accurate results when executed on unseen data sets.

Interspecies transmission of porcine-originated G4P[6] rotavirus A between pigs and humans: a synchronized spatiotemporal approach.

As a leading viral cause of acute gastroenteritis in both humans and pigs, rotavirus A (RVA) poses a potential public health concern. Although zoonotic spillover of porcine RVA strains to humans is sporadic, it has been detected worldwide. The origin of chimeric human-animal strains of RVA is closely linked to the crucial role of mixed genotypes in driving reassortment and homologous recombination, which play a major role in shaping the genetic diversity of RVA.

The thick-borne encephalitis caused by alimentary transmission - case series report.

Tick-borne encephalitis (TBE) is a central nervous system zoonotic disease transmitted by ticks. Tick-borne encephalitis virus (TBEV) is one of the main causes of lymphocytic meningitis in the areas of its endemic occurrence. A mode of transmission of TBEV which is rarely observed in clinical practice is an alimentary transmission through consumption of unpasteurised dairy products from infected animals.

The prevalence of smoking cigarettes among HIV-infected patients after a decade. Single-center analysis.

Objectives: Smoking habit is known to be a risk factor for the development of multiple diseases and conditions, premature death, and worse quality of life. The prevalence of smoking in PLWH is 2-3 times higher than in the general population. The study aimed to evaluate how the prevalence of smoking has changed among PLWH over the past decade.

A comparative analysis of the second and third wave of the Covid-19 pandemic: an experience from a tertiary care hospital in Western India.

As the world was still recovering from the 2020 pandemic, the devastating impact of Covid-19 driven by the Delta variant shook the world in 2021. As the second wave was declining, there was an unusual surge in Covid-19 positive cases by the end of 2021 which led to global concern about the change in virus characteristics. Whole genome sequencing is critical for understanding a rapidly progressing pandemic.

Changes in characteristics of patients with hepatitis C virus-related cirrhosis from the beginning of the interferon-free era.

Background: Nearly 290000 patients with chronic hepatitis C die annually from the most severe complications of the disease. One of them is liver cirrhosis, which occurs in about 20% of patients chronically infected with the hepatitis C virus (HCV). Direct-acting antivirals (DAAs), which replaced interferon (IFN)-based regimens, significantly improved the prognosis of this group of patients, increasing HCV eradication rates and tolerability of therapy.

Late HIV diagnosis among migrant women living in Europe - a systematic review of barriers to HIV testing.

Objectives: HIV transmission persists in Europe, with migrants accounting for over two-fifths of new diagnoses. Over half of all women in Europe are diagnosed late - particularly migrant women. Therefore, an updated understanding of migrant women's needs is crucial to inform inclusive and relevant HIV research, services, and policies.

Commercially available SARS-CoV-2 RT-qPCR diagnostic tests need obligatory internal validation.

Although infection with severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) does not appear to be as serious a threat to public health as it was in 2020-2021, the increased transmissibility of multiple Omicron descendants may constitute a continuous challenge for health care systems, and reliable detection of new variants is still imperative. This study evaluates the performance of three SARS-CoV-2 diagnostic tests: Novel Coronavirus (2019-nCoV) Real Time Multiplex RT-PCR Kit (Liferiver); Vitassay qPCR SARS-CoV-2 (Vitaassay) and TaqPath COVID‑19 CE-IVD RT-PCR Kit (Thermo Fisher Scientific). The analytical sensitivity of the assays as well as their specificity were determined with the use of synthetic nucleic acid standards and clinical samples.

Integrated analysis of multiple transcriptomic data identifies ST8SIA6‑AS1 and LINC01093 as potential biomarkers in HBV‑associated liver cancer.

The mechanisms of long-non-coding RNAs (lncRNAs) in hepatitis B virus (HBV) infection-associated liver cancer remain largely unclear. Therefore, the aim of the present study was to investigate the regulatory mechanisms of lncRNAs in this disease. HBV-liver cancer related transcriptome expression profile data (GSE121248 and GSE55092) from the Gene Expression Omnibus database and survival prognosis information from The Cancer Genome Atlas (TCGA) database were obtained for analysis.
