Has the HCV cascade of care changed among people who inject drugs in England since the introduction of direct-acting antivirals?

Background: In England, over 80 % of those with hepatitis C virus (HCV) infection have injected drugs. We quantified the HCV cascade of care (CoC) among people who inject drugs (PWID) in England and determined whether this improved after direct-acting antivirals (DAAs) were introduced.

Methods: We analysed data from nine rounds of national annual cross-sectional surveys of PWID recruited from drug services (2011-2019; N = 12,320).

Adverse health outcomes among people who inject drugs who engaged in recent sex work: findings from a national survey.

Objectives: This study explores trends in sex work among people who inject drugs (PWID) by gender and the relationship between sex work and adverse health outcomes including overdose, injection-site, and blood-borne virus (BBV) infections.

Study Design: The Unlinked Anonymous Monitoring Survey of PWID is an annual cross-sectional survey that monitors BBV prevalence and behaviours, including transactional sex, among PWID recruited through specialist services in England, Wales, and Northern Ireland.

Methods: Trends in sex work among PWID (2011-2021) were described.

Two-Experiment Examination of Habitual and Manipulated Foot Placement Angles on the Kinetics, Kinematics, and Muscle Forces of the Barbell Back Squat in Male Lifters.

This two-experiment study aimed to examine the effects of different habitual foot placement angles and also the effects of manipulating the foot placement angle on the kinetics, three-dimensional kinematics and muscle forces of the squat. In experiment 1, seventy lifters completed squats at 70% of their one repetition maximum using a self-preferred placement angle. They were separated based on their habitual foot angle into three groups HIGH, MEDIUM and LOW.

A Multi-Experiment Investigation of the Effects Stance Width on the Biomechanics of the Barbell Squat.

This two-experiment study aimed to explore habitual and manipulated stance widths on squat biomechanics. In experiment one, 70 lifters completed back squats at 70%, 1 repetition maximum (1RM), and were split into groups (NARROW < 1.06 * greater trochanter width (GTW), MID 1.

The Effects of Sprint vs. Resisted Sled-Based Training; an 8-Week in-Season Randomized Control Intervention in Elite Rugby League Players.

The aim of the current study was to examine the efficacy of resisted sled-based training compared to traditional unresisted sprint training in terms of mediating improvements in speed, agility, and power during an eight-week period of in-season training in elite rugby league players. Participants were randomly separated into either resisted sled or traditional sprint-based training groups and they completed an eight-week in-season training block with training prescribed based on the group to which they were assigned. Measures of 5 m, 10 m, and 20 m sprint times in addition to countermovement jump height and 505-agility test time were measured at baseline, four-weeks and eight-weeks.

The impact of direct-acting antivirals on hepatitis C viraemia among people who inject drugs in England; real-world data 2011-2018.

Direct-acting antiviral (DAA) therapy for anybody with viraemic HCV infection has been scaled-up in England since 2017. To assess early impacts, we investigated trends in, and factors associated with, HCV viraemia among people who inject drugs (PWID). We also examined trends in self-reported treatment access.

Post-vaccination HPV seroprevalence among female sexual health clinic attenders in England.

Background: The National HPV Immunisation Programme was introduced in England in September 2008 using the HPV16/18 bivalent vaccine. We conducted serological surveillance to explore vaccination coverage levels. We also conducted a case-control study to investigate a hypothesised cross-protective effect of the HPV16/18 vaccine against genital warts.

Preliminary indications of the burden of COVID-19 among people who inject drugs in England and Northern Ireland and the impact on access to health and harm reduction services.

Objective: The aim of the study was to describe the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic on people who inject drugs (PWID) in England, Wales and Northern Ireland.

Study Design: This is a cross-sectional Unlinked Anonymous Monitoring (UAM) Survey of PWID.

Methods: People who had ever injected psychoactive drugs were recruited to the UAM Survey by specialist drug/alcohol services in England, Wales and Northern Ireland.

Factors associated with skin and soft tissue infections among people who inject drugs in the United Kingdom: A comparative examination of data from two surveys.

Background: People who inject drugs (PWID) are at high risk of injection-related skin and soft tissue infections (SSTI). If not treated promptly, these can lead to serious health complications, which are a considerable healthcare burden. Data from two community surveys, with different approaches, were used to assess SSTI prevalence and associated factors among PWID to inform intervention implementation.

Reliable and efficient scale to assess upper motor neuron disease burden in amyotrophic lateral sclerosis.

Background: Validation of biomarkers of upper motor neuron (UMN) impairment in amyotrophic lateral sclerosis (ALS) requires a reliable clinical assessment of UMN findings. The Penn Upper Motor Neuron Score© (PUMNS) is a standardized measure of UMN signs in ALS. Our aims were to evaluate its intra- and inter-rater reliability, and to examine inter-item reliability as a proxy for item relatedness and scale efficiency.

Yield of next-generation neuropathy gene panels in axonal neuropathies.

The use and utility of targeted gene panels for diagnosing the type of Charcot-Marie-Tooth have grown rapidly because commercial gene panels that contain most of the relevant genes are available and affordable for many patients. We used a targeted gene panel to analyze 175 patients who had an unexplained axonal polyneuropathy affecting large myelinated axons, 86 of whom reported a family history of neuropathy, and 89 of whom did not. In patients reporting a family history, the panel identified a pathogenic variant causing the neuropathy in six cases (7%); in patients not reporting a family history, the gene panel identified pathogenic variants causing neuropathy in two patients (2%).

Are there missed opportunities for vaccinating against hepatitis B among people who inject drugs in the UK?

Sustaining the impact of hepatitis B virus (HBV) vaccination on incidence and prevalence of HBV infection requires increasing and maintaining the uptake of vaccine among those at risk. In recent years, the level of vaccine uptake among people who inject drugs (PWID) in the UK has levelled-off. Data (2015-2016) from the national unlinked-anonymous monitoring survey of PWID, an annual survey that collects data from PWID across England, Wales and Northern Ireland, were used to examine HBV vaccine uptake.

Acute Manifestations of Neuromuscular Disease.

Neuromuscular emergencies may be defined as disorders or exacerbation of diseases of the peripheral nervous system that are rapidly progressive and potentially life-threatening. Such disorders can affect any level of the peripheral nervous system, from the muscle to the anterior horn cell. While their clinical manifestations may vary, severe morbidity and mortality is most frequently the result of neuromuscular respiratory failure.

Background: The national human papillomavirus (HPV) immunization program was introduced in England in September 2008 using the bivalent vaccine.

Methods: We collected residual vulva-vaginal swab specimens from 16 to 24-year-old women attending for chlamydia screening between 2010 and 2016 and tested for HPV DNA. We compared changes in type-specific (vaccine and nonvaccine) HPV prevalence over time and association with vaccination coverage.

Sexualised drug use in the United Kingdom (UK): A review of the literature.

Background: Sexualised drug use (SDU) refers to the use of drugs in a sexual context. This includes 'Chemsex'- the use of drugs (specifically crystal methamphetamine, GHB/GBL and mephedrone) before or during planned sexual activity to sustain, enhance, disinhibit or facilitate the experience. Here we aimed to synthesise available UK prevalence data for Chemsex, SDU and the use of Chemsex drugs in an undefined context (CDU) in men who have sex with men (MSM).

Neuromuscular Disorders in Pregnancy.

Neuromuscular disorders may present and progress differently in women than in men. During pregnancy, medication adjustment, hormonal effects, and other alterations in physiology may influence the manifestation of a variety of neuromuscular disorders. The expression of existing conditions may change; previously asymptomatic conditions may be unmasked, or entirely new conditions may develop.
