UK Nutrition Research Partnership workshop: Nutrition and frailty-opportunities for prevention and treatment.

Frailty is a syndrome of growing importance given the global increase in the number of older people. While frailty is a complex, multifactorial process, poor nutritional status is considered to be a key contributor to its pathophysiology. However, the role of nutrition and its influence on the development and progression of frailty is poorly understood.

Hemostasis Proteins in Invasive Meningococcal and Nonmeningococcal Infections: A Prospective Multicenter Study.

Objectives: We aimed to describe the variation of hemostasis proteins in children with bacterial infections due to different pathogens ( Neisseria meningitidis, Streptococcus pneumoniae, Staphylococcus aureus , and group A streptococcus [GAS]) and to study hemostasis proteins in relation to mortality.

Design: Preplanned analysis in prospective cohort study.

Setting: Hospitals in five European countries (Austria, The Netherlands, Spain, Switzerland, and the United Kingdom).

Variation in CFHR3 determines susceptibility to meningococcal disease by controlling factor H concentrations.

Neisseria meningitidis protects itself from complement-mediated killing by binding complement factor H (FH). Previous studies associated susceptibility to meningococcal disease (MD) with variation in CFH, but the causal variants and underlying mechanism remained unknown. Here we attempted to define the association more accurately by sequencing the CFH-CFHR locus and imputing missing genotypes in previously obtained GWAS datasets of MD-affected individuals of European ancestry and matched controls.

Patients With Diabetes at High Bleeding Risk With 1-Month Dual Antiplatelet Therapy: Onyx ONE Clear Results.

Background: Patients with diabetes mellitus (DM) are at a higher risk of ischemic events compared with patients without DM. Percutaneous coronary intervention (PCI) with the Resolute Onyx zotarolimus-eluting stent (ZES) followed by 1-month dual antiplatelet therapy (DAPT) is safe and effective in patients with high bleeding risk. However, outcomes in patients with DM are not fully understood.

Sex differences in febrile children with respiratory symptoms attending European emergency departments: An observational multicenter study.

Objective: To assess sex differences in presentation and management of febrile children with respiratory symptoms attending European Emergency Departments.

Design And Setting: An observational study in twelve Emergency Departments in eight European countries.

Patients: Previously healthy children aged 0-<18 years with fever (≥ 38°C) at the Emergency Department or in the consecutive three days before Emergency Department visit and respiratory symptoms were included.

Febrile children with comorbidities at the emergency department - a multicentre observational study.

Unlabelled: We aimed to describe characteristics and management of children with comorbidities attending European emergency departments (EDs) with fever. MOFICHE (Management and Outcome of Fever in children in Europe) is a prospective multicentre study (12 European EDs, 8 countries). Febrile children with comorbidities were compared to those without in terms of patient characteristics, markers of disease severity, management, and diagnosis.

Milk intake across adulthood and muscle strength decline from mid- to late life: the MRC National Survey of Health and Development.

Milk is a source of several nutrients which may be beneficial for skeletal muscle. Evidence that links lower milk intake with declines in muscle strength from midlife to old age is lacking. We used data from the Medical Research Council National Survey of Health and Development to test sex-specific associations between milk consumption from age 36 to 60-64 years, low grip strength (GS) or probable sarcopenia, and GS decline from age 53 to 69 years.

Exposure to bile and gastric juice can impact the aerodigestive microbiome in people with cystic fibrosis.

Studies of microbiota reveal inter-relationships between the microbiomes of the gut and lungs. This relationship may influence the progression of lung disease, particularly in patients with cystic fibrosis (CF), who often experience extraoesophageal reflux (EOR). Despite identifying this relationship, it is not well characterised.

Conjunctival epithelial cells resist productive SARS-CoV-2 infection.

Conjunctival epithelial cells, which express viral-entry receptors angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine type 2 (TMPRSS2), constitute the largest exposed epithelium of the ocular surface tissue and may represent a relevant viral-entry route. To address this question, we generated an organotypic air-liquid-interface model of conjunctival epithelium, composed of basal, suprabasal, and superficial epithelial cells, and fibroblasts, which could be maintained successfully up to day 75 of differentiation. Using single-cell RNA sequencing (RNA-seq), with complementary imaging and virological assays, we observed that while all conjunctival cell types were permissive to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome expression, a productive infection did not ensue.

Osteoarticular Infections in Pediatric Hospitals in Europe: A Prospective Cohort Study From the EUCLIDS Consortium.

Background: Pediatric osteoarticular infections (POAIs) are serious diseases requiring early diagnosis and treatment.

Methods: In this prospective multicenter cohort study, children with POAIs were selected from the European Union Childhood Life-threatening Infectious Diseases Study (EUCLIDS) database to analyze their demographic, clinical, and microbiological data.

Results: A cohort of 380 patients with POAIs, 203 with osteomyelitis (OM), 158 with septic arthritis (SA), and 19 with both OM and SA, was analyzed.

Molecular pathogenesis and systemic therapies for hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) remains one of the most prevalent and deadliest cancers. The poor outcome associated with HCC is dramatically changing due to the advent of effective systemic therapies. Here we discuss the molecular pathogenesis of HCC, molecular classes and determinants of heterogeneity.

Health professional and patient views of a novel prognostic test for melanoma: A theoretically informed qualitative study.

Objectives: Cutaneous melanoma rates are steadily increasing. Up to 20% of patients diagnosed with AJCC Stage I/II melanomas will develop metastatic disease. To date there are no consistently reliable means to accurately identify truly high versus low-risk patient subpopulations.

Recommendations for the surveillance of mental health problems in childhood, adolescent, and young adult cancer survivors: a report from the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Survivors of childhood, adolescent, and young adult (diagnosed when <25 years of age) cancer are at risk of mental health problems. The aim of this clinical practice guideline is to harmonise international recommendations for mental health surveillance in survivors of childhood, adolescent, and young adult cancer. This guideline was developed by a multidisciplinary panel of experts under the sponsorship of the International Guideline Harmonization Group.

Excitability properties of mouse and human skeletal muscle fibres compared by muscle velocity recovery cycles.

Mouse models of skeletal muscle channelopathies are not phenocopies of human disease. In some cases (e.g.

First-in-human, open-label, phase 1/2 study of the monoclonal antibody programmed cell death protein-1 (PD-1) inhibitor cetrelimab (JNJ-63723283) in patients with advanced cancers.

Purpose: To assess the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of cetrelimab (JNJ-63723283), a monoclonal antibody programmed cell death protein-1 (PD-1) inhibitor, in patients with advanced/refractory solid tumors in the phase 1/2 LUC1001 study.

Methods: In phase 1, patients with advanced solid tumors received intravenous cetrelimab 80, 240, 460, or 800 mg every 2 weeks (Q2W) or 480 mg Q4W. In phase 2, patients with melanoma, non-small-cell lung cancer (NSCLC), and microsatellite instability-high (MSI-H)/DNA mismatch repair-deficient colorectal cancer (CRC) received cetrelimab 240 mg Q2W.

Ageing contributes to phenotype transition in a mouse model of periodic paralysis.

Background: Periodic paralysis (PP) is a rare genetic disorder in which ion channel mutation causes episodic paralysis in association with hyper- or hypokalaemia. An unexplained but consistent feature of PP is that a phenotype transition occurs around the age of 40, in which the severity of potassium-induced muscle weakness declines but onset of fixed, progressive weakness is reported. This phenotype transition coincides with the age at which muscle mass and optimal motor function start to decline in healthy individuals.

Recovery from resistance exercise in older adults: a protocol for a scoping review.

Introduction: Resistance exercise has been shown to improve muscle health in older adults and is recommended as a front-line treatment for many health conditions, including sarcopenia and frailty. However, despite considerable research detailing the potential benefits of resistance exercise programmes, little is known about how older adults recover from individual exercise sessions. This scoping review will examine the current evidence surrounding the acute post-exercise effects of resistance exercise and the exercise recovery process in older adults to inform future research and exercise prescription guidelines for older adults.

The effects of different parenteral nutrition lipid formulations on clinical and laboratory endpoints in patients receiving home parenteral nutrition: A systematic review.

Background: Home parenteral nutrition (HPN) is a life-sustaining therapy for individuals with intestinal failure in a community setting. It refers to the intravenous infusion of macronutrients, micronutrients, fluids and electrolytes. Routinely used HPN solutions contain different quantities of these components.

Rapid Viral Testing and Antibiotic Prescription in Febrile Children With Respiratory Symptoms Visiting Emergency Departments in Europe.

Background: Inappropriate antibiotic prescribing often occurs in children with self-limiting respiratory tract infections, contributing to antimicrobial resistance. It has been suggested that rapid viral testing can reduce inappropriate antibiotic prescribing. We aimed to assess the association between rapid viral testing at the Emergency Department (ED) and antibiotic prescription in febrile children.

Reproductive justice for the haunted Nordic welfare state: Race, racism, and queer bioethics in Finland.

The Nordic welfare state aims to offer universal healthcare and achieve good health, bar none. We discuss past and present moral blind spots in welfare state bioethics through reproductive justice and queer bioethics, particularly focusing on race and racism, based on ethnographic data from Finland. Globally portrayed as aspirational and mostly uninterrogated, it is crucial to have a thorough bioethical evaluation of a Nordic model informed by Black and queer perspectives.

SARS-CoV-2 Infection and COVID-19 Outcomes in Rheumatic Diseases: A Systematic Literature Review and Meta-Analysis.

Objective: The relative risk of SARS-CoV-2 infection and COVID-19 disease severity among people with rheumatic and musculoskeletal diseases (RMDs) compared to those without RMDs is unclear. This study was undertaken to quantify the risk of SARS-CoV-2 infection in those with RMDs and describe clinical outcomes of COVID-19 in these patients.

Methods: We conducted a systematic literature review using 14 databases from January 1, 2019 to February 13, 2021.
