Understanding Participation in Integrated Youth Mental Health Service Research: Lessons Learned From a Feasibility Study With Jigsaw.

Introduction: Research with integrated youth mental health services (IYMHS) has been criticised for low quality, with difficulties in recruiting and retaining participants in studies which can introduce bias. This feasibility study aimed to investigate the "real-world research" barriers and facilitators to recruitment and retention arising in a longitudinal study with Jigsaw, the National Centre for Youth Mental Health in Ireland, and to provide recommendations for conducting IYMHS research in future.

Methods: A qualitative study was conducted to investigate recruitment and retention difficulties.

A preliminary ex vivo diffusion tensor imaging study of distinct aortic morphologies.

Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.

Factors associated with statural growth in pediatric kidney transplant recipients with focus on metabolic acidosis.

Background: We investigated factors associated with post-transplant growth in pediatric kidney transplant (KTx) recipients with a focus on plasma bicarbonate (HCO3) and estimated the effect of alkali treatment on growth.

Methods: In this study of the CERTAIN Registry, data were collected up to 5 years post-transplant. Generalized Additive Mixed Models were applied to assess the association between post-transplant growth and covariates.

Impact of measurement location on direct mitral regurgitation quantification using 4D flow CMR.

Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the ideal location of a measurement plane remains unclear. This study aims to systematically examine how varying measurement locations affect RVol quantification and determine the optimal location using the momentum conservation principle of a free jet.

Global impact of 10- and 13-valent pneumococcal conjugate vaccines on pneumococcal meningitis in all ages: the PSERENADE project.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.

Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.

Using Laboratory Test Results for Surveillance During a New Outbreak of Acute Hepatitis in 3-Week- to 5-Year-Old Children in the United Kingdom, the Netherlands, Ireland, and Curaçao: Observational Cohort Study.

Background: In March 2022, a concerning rise in cases of unexplained pediatric hepatitis was reported in multiple countries. Cases were defined as acute hepatitis with serum transaminases >500 U/L (aspartate transaminase [AST] or alanine transaminase [ALT]) in children aged 16 years or younger. We explored a simple federated data analytics method to search for evidence of unreported cases using routinely held data.

Nano- and meso-scale aggregation of poly(N-isopropylacrylamide) below the lower critical solution temperature: A wide-angle dynamic light scattering study.

Poly-N-isopropylacrylamide (PNIPAm), a thermorresponsive polymer, highly soluble in water below its lower critical solution temperature (LCST), is widely used in biomedical applications like drug delivery. Being able to measure PNIPAm size and aggregation state in solution quickly, inexpensively, and accurately below the LCST is critical when stoichiometric particle or molecular ratios are required. Dynamic light scattering (DLS) is probably the most widely available, and inexpensive nanoparticle sizing technique, but there are limitations with respect to sample polydispersity.

Dilemma: Utilizing the activation decision-construction-action theory to understand and predict children's hypothetical decisions to conceal cases of school bullying.

The Decision component of the Activation-Decision-Construction-Action theory (ADCAT) proposes that if people perceive the benefits of lying higher than the truth, they are more likely to lie. To expand on the existing ADCAT research, the current study investigated the cost-benefit appraisals of 115 children ages 7-to-14 when concealing information about school bullying. Further, the current study examined the impact of the type of bullying (verbal vs.

Exploring brain health awareness and dementia risk in young adults: A focus group study.

Novel nutrition strategies in gastric and esophageal cancer.

Introduction: Advances in treatment strategies for gastric and esophageal cancer have led to improved long-term outcomes, however the local and systemic effects of the primary tumor, neoadjuvant therapies and surgery, result in specific nutritional challenges. Comprehensive nutritional evaluation and support represents a core component of multidisciplinary holistic care for this patient population.

Areas Covered: We provide a detailed overview of nutritional challenges in gastric and esophageal cancer, with a focus on malignant obstruction, preoperative optimization and survivorship.

ISCT MSC committee statement on the US FDA approval of allogenic bone-marrow mesenchymal stromal cells.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.

Rationale and Design of the Prevail Global Trial Program Evaluating the Prevail Drug-Coated Balloon in Patients with In-stent Restenosis and De Novo Small Vessel Disease.

Background And Rationale: In-stent restenosis (ISR) remains the leading cause of treatment failure following percutaneous coronary intervention (PCI) with contemporary drug-eluting stents. Especially in small caliber coronary arteries, restenosis is common following PCI and represents a treatment challenge. Drug-coated balloons (DCB) are an attractive alternative to stents for treatment of both ISR and small vessel disease.

Atrial fibrillation versus. atrial myopathy in thrombogenesis: Two sides of the same coin?

Atrial fibrillation (AF) and atrial myopathy are recognized contributors to cardiovascular morbidity, particularly ischemic stroke. AF poses an elevated risk of thrombogenesis due to irregular heart rhythm leading to blood stasis and clot formation. Atrial myopathy, marked by structural and functional alterations in the atria, is emerging as a crucial factor influencing thromboembolic events, independently of AF.

Hidradenitis suppurativa.

Hidradenitis suppurativa is a chronic inflammatory disease characterised by painful, deep-seated nodules, abscesses, and draining tunnels in the skin of axillary, inguinal, genitoanal, or inframammary areas. In recent years, the body of knowledge in hidradenitis suppurativa has advanced greatly. This disorder typically starts in the second or third decade of life.

Structural and functional analysis of SAM-dependent N-methyltransferases involved in ovoselenol and ovothiol biosynthesis.

Thio/selenoimidazole Nπ-methyltransferases are an emerging family of enzymes catalyzing the final step in the production of the S/Se-containing histidine-derived antioxidants ovothiol and ovoselenol. These enzymes, prevalent in prokaryotes, show minimal sequence similarity to other methyltransferases, and the structural determinants of their reactivities remain poorly understood. Herein, we report ligand-bound crystal structures of OvsM from the ovoselenol pathway as well as a member of a previously unknown clade of standalone ovothiol-biosynthetic Nπ-methyltransferases, which we have designated OvoM.
