Risk factors for hepatocellular carcinoma associated with hepatitis C genotype 3 infection: A systematic review.

Background: Hepatitis C virus (HCV) is a blood-borne virus which globally affects around 79 million people and is associated with high morbidity and mortality. Chronic infection leads to cirrhosis in a large proportion of patients and often causes hepatocellular carcinoma (HCC) in people with cirrhosis. Of the 6 HCV genotypes (G1-G6), genotype-3 accounts for 17.

Study protocol: the ILANA study - exploring optimal implementation strategies for long-acting antiretroviral therapy to ensure equity in clinical care and policy for women, racially minoritised people and older people living with HIV in the UK - a qualitative multiphase longitudinal study design.

Introduction: Cabotegravir and rilpivirine (CAB+RPV long-acting (LA)) is recommended as a treatment for HIV-1 allowing people living with HIV to receive 2 monthly injectable treatment, rather than daily pills. Providing injectable therapy in a system designed to provide and manage study participants on oral treatments poses logistical challenges namely how resources are used to accommodate patient preference within constrained health economies with capacity limitations. In this pragmatic multicentre study, we aim to understand the implementation of CAB-RPV-LA administration in two settings via mixed methods to explore perspectives of participants and the clinical team delivering CAB+RPV LA.

Evaluation of the ® Prep&Amp UM RT-PCR for detection of SARS-CoV-2 from nasopharyngeal swabs without prior nucleic acid eluate extraction.

Here we describe a retrospective clinical evaluation of the QIAGEN SARS-CoV-2 Prep&Amp UM RT-PCR assay that detects SARS-CoV-2 RNA without the need for a nucleic acid eluate extraction procedure. Using Roche SARS-CoV-2 RT-PCR on the cobas® 8800 platform as a reference standard, a total of 225 confirmed SARS-CoV-2 positive and 320 negative nasopharyngeal swabs in viral transport media, were used to evaluate the assay. Using the RT-PCR cycle threshold as a semi-quantitative marker of viral load, an assessment of over 370,000 SARS-CoV-2 RT-PCR positive results was used in the design of the reference positive specimen cohort.

Prognostic indicators and outcomes of hospitalised COVID-19 patients with neurological disease: An individual patient data meta-analysis.

Background: Neurological COVID-19 disease has been reported widely, but published studies often lack information on neurological outcomes and prognostic risk factors. We aimed to describe the spectrum of neurological disease in hospitalised COVID-19 patients; characterise clinical outcomes; and investigate factors associated with a poor outcome.

Methods: We conducted an individual patient data (IPD) meta-analysis of hospitalised patients with neurological COVID-19 disease, using standard case definitions.

An Overview of SARS-CoV-2 Molecular Diagnostics in Europe.

The COVID-19 pandemic has led to the rapid development of a plethora of molecular diagnostic assays with real-time polymerase chain reaction (RT-PCR) at the forefront. In this review, we will discuss the history and utility of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) molecular diagnostics and the associated current and future regulatory process in Europe. We will assess the performance characteristics of a range of the most common SARS-CoV-2 molecular tests currently used in Europe with a focus on as rapid molecular platforms, stand-alone RT-PCR kits, the role of low-throughput and high-throughput end-to-end testing platforms, and the rapidly evolving field of SARS-CoV-2 variant of concern identification.

Evaluation of a novel direct RT-LAMP assay for the detection of SARS-CoV-2 from saliva samples in asymptomatic individuals.

Large scale screening of health care workers and the general population for asymptomatic COVID-19 infection requires modalities that are amenable to testing at scale while retaining acceptable levels of sensitivity and specificity. This study evaluated a novel COVID-19 Direct-RT LAMP assay using saliva samples in asymptomatic individuals by comparison to RT-PCR. Additional studies were performed using VTM collected from routine diagnostic testing.

Use of pritelivir in refractory aciclovir-resistant herpes simplex virus type 2.

Recurrence of mucocutaneous herpes simplex virus (HSV) infections is common in immunosuppressed patients. Thymidine kinase mutations conferring resistance to the antiviral agent aciclovir have been observed in such patients. Recommended second-line therapeutic agents against HSV are associated with significant side effects contributing to disease burden.

Real-world SARS CoV-2 testing in Northern England during the first wave of the COVID-19 pandemic.

Objectives: SARS-CoV-2 emerged in South Asia in 2019 and has resulted in a global pandemic. Public Health England (PHE) Manchester rapidly escalated testing for SARS-CoV-2 in the highest COVID-19 incidence location in England. The results of the PHE Manchester SARS-CoV-2 surveillance during the first wave are presented.

Limited Capability for Testing Mycobacterium tuberculosis for Susceptibility to New Drugs.

We surveyed availability of phenotypic drug susceptibility testing for drug-resistant Mycobacterium tuberculosis in Europe. Of 27 laboratories, 17 tested for linezolid, 11 for clofazimine, 9 for bedaquiline, and 6 for delamanid during 2019. Our findings indicate that testing capacity for newer and repurposed tuberculosis drugs exists, but its availability is limited.

Middle East respiratory syndrome coronavirus (MERS-CoV) - Surveillance and testing in North England from 2012 to 2019.

Background: Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in Saudi Arabia in 2012 and caused an epidemic in the Middle East. Public Health England (PHE) Manchester is one of the two PHE centres in the UK that perform testing for MERS-CoV. The results of the PHE Manchester MERS surveillance from 2012 to 2019 are presented in this report.

Assessment of fever in the returning traveller.

Evaluation of people returning from trips abroad with fever is an important skill for all general physicians given the increasing trend in foreign travel. This evaluation should comprise a detailed travel history, thorough clinical examination, appropriate initial tests and a knowledge of when to ask for further advice. An understanding of the incubation periods of common imported infections and a syndromic approach to patients' symptoms is helpful in order to narrow down the likely diagnosis.

HIV, HCV and HBV: A Review of Parallels and Differences.

Elimination of the three blood-borne viruses-human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV)-as public health issues may be plausible in the near future. Spectacular advances have been made with the introduction of highly effective antiviral agents into clinical practice, and prevention strategies are available for all three infections. Effective disease control, laid out by WHO global strategies, is currently feasible for all three viruses.
