Background: Research suggest that personality traits influence the mood and somatic symptoms in various different clinical populations. Neuroticism, extraversion, conscientiousness, openness to experience, and agreeableness have been identified as potential predictors of mood and somatic symptoms. However, the literature on personality traits and symptom outcomes in multiple sclerosis (MS) is limited, highlighting the necessity for more in-depth research.

Objectives: Limited research has explored caregivers' activities beyond caregiving duties, which may offer positive experiences and counterbalance caregiving stress. This study aimed to (a) identify the most pleasant non-caregiving activities, (b) assess time allocation based on activity categories and pleasantness, and (c) investigate the association between activity pleasantness and duration, considering differences between caregivers to older adults with Alzheimer's Disease and Related Dementias (ADRD) and those without.

Methods: This study included 2,136 caregivers (33% ADRD) from the 2017 National Study of Caregiving (NSOC) who participated in a time diary interview.

As one of the most efficacious glaucoma surgical techniques, trabeculectomy is considered by many surgeons to be the "gold standard" intra-ocular pressure (IOP)-reducing intervention. The purpose of this study is to present our intra-operative flow-adjusted surgical method, which aims to provide safety and efficacy more simply than previous methods. Retrospectively, we evaluated outcomes for trabeculectomy or phacotrabeculectomy in surgery-naïve eyes over three years for patients with glaucoma not associated with other ocular co-morbidities.

Mediation analyses allow for exploration of causal mechanisms that explain how a predictor is related to an outcome. Tests of mediation are fundamental to addressing some of the most consequential questions in rehabilitation science. In recent decades, the development of easy-to-use analytical tools has made conducting statistical tests of mediation more accessible to researchers.

Background: Fatigue is one of the most disabling symptoms reported by people with multiple sclerosis. Although behavioural and pharmacological interventions might be partly beneficial, their combined effects have not been evaluated for multiple sclerosis fatigue, or examined with sufficient consideration of characteristics that might affect treatment response. In this comparative effectiveness research trial, we compared the effectiveness of cognitive behavioural therapy (CBT), modafinil, and their combination for treating multiple sclerosis fatigue.

Background: Cognitive dysfunction is a common problem in multiple sclerosis (MS). Progress toward understanding and treating cognitive dysfunction is thwarted by the limitations of traditional cognitive tests, which demonstrate poor sensitivity and ecological validity. Ambulatory methods of assessing cognitive function in the lived environment may improve the detection of subtle changes in cognitive function and the identification of predictors of cognitive changes and downstream effects of cognitive change on other functional domains.

Targeting current therapies to treat or prevent the loss of pancreatic islet β-cells in Type 1 Diabetes (T1D) may provide improved efficacy and reduce off-target effects. Current efforts to target the β-cell are limited by a lack of β-cell-specific targets and the inability to test multiple targeting moieties with the same delivery vehicle. Here, we fabricate a tailorable polycaprolactone nanocapsule (NC) in which multiple different targeting peptides can be interchangeably attached for β-cell-specific delivery.

The generation of stem cell-derived β-like cells (sBCs) holds promise as not only an abundant insulin-producing cell source for replacement therapy of type 1 diabetes (T1D) but also as an invaluable model system for investigating human β-cell development, immunogenicity, and function. Several groups have developed methodology to direct differentiate human pluripotent stem cells into pancreatic cell populations that include glucose-responsive sBCs. Nevertheless, the process of generating sBCs poses substantial experimental challenges.

Background: Cardiac arrest is a common and devastating emergency of both the heart and brain. More than 380,000 patients suffer out-of-hospital cardiac arrest annually in the USA. Induced cooling of comatose patients markedly improved neurological and functional outcomes in pivotal randomized clinical trials, but the optimal duration of therapeutic hypothermia has not yet been established.

To facilitate the interrogation of protein function at scale, we have developed high-throughput insertion of tags across the genome (HITAG). HITAG enables users to rapidly produce libraries of cells, each with a different protein of interest C-terminally tagged. HITAG is based on a modified strategy for performing Cas9-based targeted insertions, coupled with an improved approach for selecting properly tagged lines.

Centrioles play important roles in the assembly of centrosomes and cilia. Centriole duplication occurs once per cell cycle and is dependent on polo-like kinase 4 (PLK4). To prevent centriole amplification, which is a hallmark of cancer, PLK4 protein levels need to be tightly regulated.

Objective: The aim of the study is to estimate the current nationwide prevalence of falls, injurious falls, concerns about falling, and information on fall prevention among people with multiple sclerosis.

Design: This is a cross-sectional national web-based survey that included 965 adult people with multiple sclerosis. Participants self-reported falls and injurious falls experienced in the past 6 months.

For over 50 years, has helped highlight important issues experienced by the disability community. We are extremely excited to continue that legacy in our role as the journal's first dual editors-in-chief, and we look forward to working with our associate editors, Kathleen Bogart and Daniel Klyce, our editorial fellows, and our large editorial board and ad hoc reviewer pool. In our tenure as the journal's editors, we will focus heavily on (a) providing exceptional service, (b) emphasizing diversity and disability identity, (c) broadening the scope of the field, (d) promoting high-quality research standards, and (e) looking ahead.

Purpose/objective: We lack critical information regarding promoting resilience in people with spinal cord injury (SCI). Living according to one's values may increase resilience. The aims of this study were to: (a) determine whether the degree to which individuals with SCI are living according to their values is associated with resilience; (b) identify values endorsed as most important; and (c) examine whether the importance of these values differs significantly by high vs.

Exploring the relationship between underlying pain mechanisms and physical activity could inform interventions to optimize physical activity in persons with multiple sclerosis (PwMS). This cross-sectional nationwide survey examined whether pain phenotype is a significant predictor of self-reported physical activity in PwMS. The study included 938 persons with a self-reported diagnosis of MS (93% reported neurologist-diagnosed MS) who completed surveys of demographic, clinical information, pain intensity, indicators of underlying pain mechanisms (Fibromyalgia Survey Criteria and painDETECT), and physical activity (Godin Leisure-Time Exercise Questionnaire).

Prcis: The iCare HOME2 tonometer generally can be considered reliable for most eyes and clinical settings, although it may produce slightly overestimated or underestimated intraocular pressure (IOP) readings in thicker and thinner corneas, respectively.

Purpose: To evaluate the accuracy, correlation, and analysis of differences in IOP measurements between the gold standard Goldmann applanation tonometer (GAT) and the new, self-measurement iCare HOME2 tonometer (icare).

Patients And Methods: In this retrospective study, patients were randomly selected from those who attended a routine examination in our clinic.
