Creative well-being is an increasing field of interest to which biomedical and social sciences have made uneven contributions. The instrumental value of culture and its subsequential public investment is grounded in the interplay of social, cultural and economic capital to attain and preserve wellbeing and health and foster social mobility. The current evidence addresses the effectiveness of arts interventions in improving illnesses.

Article Synopsis
  • Human genetic studies often lack diversity, which limits understanding of disease causes and health disparities.
  • The Department of Veterans Affairs Million Veteran Program analyzed data from a diverse group of 635,969 veterans, revealing 13,672 genomic risk loci, with significant findings particularly from non-European populations.
  • The research identified causal variants across 613 traits, showing that genetic similarities exist across populations and emphasizing the importance of including underrepresented groups in genetic research.

Introduction: The prevalence of multiple long-term conditions (M-LTCs) increases as adults age and impacts quality of life and health outcomes. To help people manage these conditions, complex behaviour change interventions are used, often based on research conducted in those with single LTCs. However, the needs of those with M-LTCs can differ due to complex health decision-making and engagement with multiple health and care teams.

Genome-wide association studies (GWAS) have underrepresented individuals from non-European populations, impeding progress in characterizing the genetic architecture and consequences of health and disease traits. To address this, we present a population-stratified phenome-wide GWAS followed by a multi-population meta-analysis for 2,068 traits derived from electronic health records of 635,969 participants in the Million Veteran Program (MVP), a longitudinal cohort study of diverse U.S.

Congenital facial palsy is a rare medical condition that causes paralysis of the facial muscles, lack of facial expression, and an unusual appearance. Findings from developmental psychology suggest that the face plays a central role in the construction of self. Semi-structured interviews were conducted with 14 adults born with congenital facial palsy.

Background/aims: Multiple sclerosis (MS) is one of the most common autoimmune disorders of the central nervous system (CNS) and the leading cause of neurological disability among young adults in the Western world. We have previously shown that the acid sphingomyelinase plays an important role in the pathogenesis of experimental autoimmune encephalomyelitis (EAE), an animal model for multiple sclerosis.

Methods: We induced adoptively transferred EAE in wildtype and acid sphingomyelinase-deficient mice.

Objective: This study examined clinicians' views of the roles of two elements of cognitive behavioral therapy (CBT) in explaining treatment outcomes-CBT techniques and the therapeutic alliance.

Method: Ninety-eight clinicians who reported delivering CBT for eating disorders completed measures addressing their beliefs about what is effective in CBT, their use of specific techniques, and their own anxiety levels.

Results: Clinicians substantially overestimated the role of both therapeutic techniques and the alliance in explaining treatment outcomes in CBT.

Chitin, a major component of fungal cell walls, is a well-known pathogen-associated molecular pattern (PAMP) that triggers defense responses in several mammal and plant species. Here, we show that two chitooligosaccharides, chitin and chitosan, act as PAMPs in grapevine (Vitis vinifera) as they elicit immune signalling events, defense gene expression and resistance against fungal diseases. To identify their cognate receptors, the grapevine family of LysM receptor kinases (LysM-RKs) was annotated and their gene expression profiles were characterized.

Background: Multiple sclerosis (MS) is a severe and common autoimmune disorder of the central nervous system. Despite the availability of several novel treatment options, the disease is still poorly controlled, since the pathophysiological mechanisms are not fully understood.

Methods: We tested the role of the acid sphingomyelinase/ceramide system in a model of MS, i.

Unlabelled: The tegument of herpesviruses is a highly complex structural layer between the nucleocapsid and the envelope of virions. Tegument proteins play both structural and regulatory functions during replication and spread, but the interactions and functions of many of these proteins are poorly understood. Here we focus on two tegument proteins from herpes simplex virus 1 (HSV-1), pUL7 and pUL51, which have homologues in all other herpesviruses.

The entry into fatherhood is a major life course transition involving the acquisition of new adult roles and responsibilities. This transition is rarely planned for young fathers, and may involve a range of challenges, not least their capacity to provide materially and financially for their child. Drawing on a Qualitative Longitudinal study of young fathers in the UK, this article charts their very different pathways through education, training and employment, showing how these are shaped by a constellation of life circumstances.

Background: Low back pain (LBP) is the world's leading cause of disability and yet poorly understood. Cross-national comparisons may motivate hypotheses about outcomes being condition-specific or related to cultural differences and can inform whether observations from one country may be generalised to another. This analysis of data from three cohort studies explored whether characteristics and outcomes differed between LBP patients visiting chiropractors in Sweden, Denmark and the UK.

Pulmonary barotrauma can cause cerebral arterial gas embolism (CAGE) from pulmonary overdistension of alveoli forcing gas into the pulmonary vasculature. We report a case of CAGE in a man found to have occult pulmonary arteriovenous malformation (PAVM) and undiagnosed obstructive sleep apnea (OSA). A 46-year-old man was admitted to the hospital for an acute seizure and left-sided weakness, with telangiectasias on his lower lip and tongue.

Background: Multiple sclerosis is the most common autoimmune disease of the central nervous system in young adults and histopathologically characterized by inflammation, demyelination and gliosis. It is considered as a CD4+ T cell-mediated disease, but also a disease-promoting role of the innate immune system has been proposed, based e.g.

Functional characterization of the Columbia root-knot nematode resistance gene R Mc1 ( blb ) in potato revealed the R gene-mediated resistance is dependent on a hypersensitive response and involves calcium. The resistance (R) gene R Mc1(blb) confers resistance against the plant-parasitic nematode, Meloidogyne chitwoodi. Avirulent and virulent nematodes were used to functionally characterize the R Mc1(blb)-mediated resistance mechanism in potato (Solanum tuberosum).

Background: Impaired sarcoplasmic reticular Ca(2+) uptake resulting from decreased sarcoplasmic reticulum Ca(2+)-ATPase type 2a (SERCA2a) expression or activity is a characteristic of heart failure with its associated ventricular arrhythmias. Recent attempts at gene therapy of these conditions explored strategies enhancing SERCA2a expression and the activity as novel approaches to heart failure management. We here explore the role of Pak1 in maintaining ventricular Ca(2+) homeostasis and electrophysiological stability under both normal physiological and acute and chronic β-adrenergic stress conditions.

Root-knot nematodes are sedentary biotrophic endoparasites that maintain a complex interaction with their host plants. Nematode effector proteins are synthesized in the oesophageal glands of nematodes and secreted into plant tissue through a needle-like stylet. Effectors characterized to date have been shown to mediate processes essential for nematode pathogenesis.
