Recombinant production platform for Group A Streptococcus glycoconjugate vaccines.

Group A Streptococcus (Strep A) is a human-exclusive bacterial pathogen killing annually more than 500,000 patients, and no current licensed vaccine exists. Strep A bacteria are highly diverse, but all produce an essential, abundant, and conserved surface carbohydrate, the Group A Carbohydrate, which contains a rhamnose polysaccharide (RhaPS) backbone. RhaPS is a validated universal vaccine candidate in a glycoconjugate prepared by chemical conjugation of the native carbohydrate to a carrier protein.

Premed Pressure: Examining whether premed students experience more academic stress compared to non-premeds.

Academic stress is one of the primary factors threatening university students' well-being and performance. Undergraduate students who are working towards applying to medical school, defined as being on the pre-medicine or "premed" pathway, are suspected to have higher academic stress compared to their peers who are not premed. However, what factors contribute to academic stress for premed students is not well understood.

Objective: Conduct a preliminary randomized trial that compared a 6-week type 2 diabetes (T2D) prevention programme to an educational video control for adults with pre-diabetes.

Methods: Adults (N = 62) with pre-diabetes were randomized to the group-delivered Project Health T2D or an educational video control, completing measures at pre-test, post-test and 3-month follow-up.

Results: Participants randomized to the intervention versus control condition showed significantly greater reductions in body fat (d = 0.

First record of Culex pipiens (Diptera: Culicidae) in Alberta: expanding distributions and ecotype patterns in a western Canadian province.

Culex pipiens is an invasive mosquito found in temperate regions globally. It is considered among the most important disease vectors worldwide and is responsible for the transmission of a range of pathogens, including West Nile virus, avian malaria, Saint Louis encephalitis, and filarial worms. Throughout its northern temperate range, this mosquito is found in 2 ecotypes: form pipiens and form molestus.

Neurological complications of immune checkpoint inhibitors: a practical guide.

Immune checkpoint inhibition unleashes the power of the immune system against tumour cells. Immune checkpoint inhibitors (ICIs) block the inhibitory effects of cytotoxic T-lymphocyte associated protein 4, programmed death protein 1, programmed death ligand 1 and lymphocyte activation gene 3 molecules on T-cells, and so enhance physiological cytotoxic effects. ICIs can significantly improve survival from cancers, including those previously associated with poor treatment response, such as metastatic melanoma.

Acceptability and Feasibility of Implementing a Home-Based HIV Pre-Exposure Prophylaxis Program in an Urban Clinic.

Personal and structural barriers to HIV pre-exposure prophylaxis (PrEP) care result in its underutilization and premature discontinuation. A home-based PrEP program comprised of telemedicine visits and/or self-administered lab testing may address some of these barriers. Our objective was to assess the acceptability and feasibility of a home-based PrEP program among stakeholders at an urban HIV and primary care clinic.

An analysis of the use of historical control data in the assessment of regulatory pesticide toxicity studies.

The concurrent control group is the most important reference for the interpretation of toxicity studies. However, pooled information on control animals from independent studies, i.e.

Real-world evidence study on the early use of cemiplimab in the UK: REACT-CEMI (Real World evidence of advanced CSCC treatment with cemiplimab).

Background: Cemiplimab was licensed in the United Kingdom (UK) in 2019 for the treatment of patients with locally advanced and metastatic CSCC not suitable for curative surgery or radiotherapy (advanced CSCC [aCSCC]). No UK multi-center studies have investigated the real-world experience of cemiplimab post marketing authorization in aCSCC.

Methods: This non-interventional retrospective study (10 UK centers) involved data collection from medical records of patients with aCSCC who initiated cemiplimab treatment between 2 July 2019 and 30 November 2020.

Predictors of the sustainability for an evidence-based eating disorder prevention program delivered by college peer educators.

Background: Despite ongoing efforts to introduce evidence-based interventions (EBIs) into mental health care settings, little research has focused on the sustainability of EBIs in these settings. College campuses are a natural place to intervene with young adults who are at high risk for mental health disorders, including eating disorders. The current study tested the effect of three levels of implementation support on the sustainability of an evidence-based group eating disorder prevention program, the Body Project, delivered by peer educators.

A CDK1 phosphorylation site on PAR-3 regulates neuroblast polarisation and sensory organ formation.

The generation of distinct cell fates during development depends on asymmetric cell division of progenitor cells. In the central and peripheral nervous system of progenitor cells respectively called neuroblasts or sensory organ precursors use PAR polarity during mitosis to control cell fate determination in their daughter cells. How polarity and the cell cycle are coupled, and how the cell cycle machinery regulates PAR protein function and cell fate determination is poorly understood.

Evaluation of Hand Action Classification Performance Using Machine Learning Based on Signals from Two sEMG Electrodes.

Classification-based myoelectric control has attracted significant interest in recent years, leading to prosthetic hands with advanced functionality, such as multi-grip hands. Thus far, high classification accuracies have been achieved by increasing the number of surface electromyography (sEMG) electrodes or adding other sensing mechanisms. While many prescribed myoelectric hands still adopt two-electrode sEMG systems, detailed studies on signal processing and classification performance are still lacking.

A three-arm randomised phase II study of the MEK inhibitor selumetinib alone or in combination with paclitaxel in metastatic uveal melanoma.

Aims: The MAPK pathway is constitutively activated in uveal melanoma (UM). Selumetinib (AZD6244, ARRY-142886), a MEK inhibitor, has shown limited activity as monotherapy in metastatic UM. Pre-clinical studies support synergistic cytotoxic activity for MEK inhibitors combined with taxanes, and here we sought to assess the clinical efficacy of combining selumetinib and paclitaxel.

Cost-effectiveness of Intervention Implementation Support for Reducing Eating Disorder Symptoms Among College Students.

Implementation support for prevention interventions is receiving increased attention, as many organizations receive training in evidence-based practices but do not deliver the interventions optimally. The Body Project, a four-session program, significantly reduces eating disorder symptoms and future disorder onset among group participants when delivered by peer educators at colleges/universities. Costs and cost-effectiveness of the program were examined using data from a randomized trial that compared three levels of implementation support at 63 colleges: (1) a train-the-trainer (TTT) workshop alone, (2) TTT plus a technical assistance (TA) workshop, or (3) TTT plus TA plus monthly quality assurance (QA) consultations.

Analysis of the initial orbital MRI in aquaporin-4 antibody-positive optic neuritis (AQP4-ON): lesion location and lesion length can be predictive of visual prognosis.

Purpose: Despite mounting evidence indicating that aquaporin-4 antibody-positive optic neuritis (AQP4-ON) presents a less favorable prognosis than other types of optic neuritis, there exists substantial heterogeneity in the prognostic outcomes within the AQP4-ON cohort. Considering the persistent debate over the role of MRI in assessing the prognosis of optic neuritis, we aim to investigate the correlation between the MRI appearance and long-term visual prognosis in AQP4-ON patients.

Methods: We retrospectively reviewed the ophthalmological and imaging data of AQP4-ON patients admitted to our Neuro-ophthalmology Department from January 2015 to March 2018, with consecutive follow-up visits for a minimum of 3 years.

Vitamin D status in post-medieval Northern England: Insights from dental histology and enamel peptide analysis at Coach Lane, North Shields (AD 1711-1857).

Objectives: The post-medieval period in Europe saw a dramatic increase in metabolic bone disease related to vitamin D deficiency (VDD). Recent paleopathological work has utilized interglobular dentin (IGD) as a proxy for poor vitamin D status during development, while enamel peptide analysis allows the identification of chromosomal sex in non-adult remains. Here we explore the relationship between sex, the presence of IGD, and macroscopic markers of VDD in an industrial era assemblage from Northeast England.

Glycopyrronium 320 μg/mL in children and adolescents with severe sialorrhoea and neurodisabilities: A randomized, double-blind, placebo-controlled trial.

Aim: To investigate the efficacy, safety, and impact on quality of life (QoL) of an oral formulation of 320 μg/mL glycopyrronium designed for children.

Method: A double-blind, placebo-controlled SALIVA (Sialanar plus orAl rehabiLitation against placebo plus oral rehabilitation for chIldren and adolescents with seVere sialorrhoeA and neurodisabilities) trial was conducted. Children (3-17 years) with neurodisabilities and severe sialorrhoea (modified Teachers Drooling Scale ≥6) were randomized to 320 μg/mL glycopyrronium or placebo, in addition to non-pharmacological standard care.

A randomized trial of two group-delivered transdiagnostic eating disorder treatments: Dissonance-based treatment versus interpersonal psychotherapy.

Objective: Test whether a group-delivered dissonance-based transdiagnostic eating disorder treatment, Body Project Treatment (BPT), produces greater reductions in eating disorder symptoms and higher abstinence from eating disorder behaviors and remittance from eating disorder diagnoses than group-delivered transdiagnostic interpersonal psychotherapy (IPT).

Method: Women with a range of eating disorders (N = 73) were randomized to 8-week group-implemented BPT or IPT and completed surveys and masked diagnostic interviews at pretest, posttest, and 6-month follow-up.

Results: Participants randomized to BPT versus IPT showed significantly greater reductions in eating disorder symptoms (d = -.
