Use of Treatment and Self-Management Methods: Perspectives and Decisions of Patients With Ulcerative Colitis.

Patients with Ulcerative Colitis (UC) seek a variety of methods to manage the physical and psychosocial burdens of illness on daily life. This study examines how individuals with UC: (1) utilize treatment and self-management methods and (2) make decisions regarding their use of these methods throughout the disease course. Adults living with UC ≥5 years and experienced ≥1 disease flare, participated in individual, semi-structured qualitative interviews.

The Mobile lifestyle intervention for food and exercise (mLife) study: Protocol of a remote behavioral weight loss randomized clinical trial for type 2 diabetes prevention.

Background: Emerging research has examined electronic and mobile health (e/mHealth) technologies for weight loss and manage of type 2 diabetes mellitus (T2DM), but few studies have focused specifically on ways to target social support behaviors that have proven to be effective. While gamifying an mHealth behavioral weight loss intervention holds promise to promote and sustain social support, there has been very little research in this area. The mobile Lifestyle Intervention for Food and Exercise study (mLife) was designed to test if receiving points for social support is an effective way to promote sustained weight loss.

A somatic genetic clock for clonal species.

Age and longevity are key parameters for demography and life-history evolution of organisms. In clonal species, a widespread life history among animals, plants, macroalgae and fungi, the sexually produced offspring (genet) grows indeterminately by producing iterative modules, or ramets, and so obscure their age. Here we present a novel molecular clock based on the accumulation of fixed somatic genetic variation that segregates among ramets.

Community Health Worker Implementation and Cost Analysis of a Plant-Based Nutrition Program.

Objective: This study describes program implementation through a research-restaurant partnership and assesses participant satisfaction, program costs, and percent body weight changes.

Methods: Participants (n = 60) in a virtual synchronous (n = 43) or virtual asynchronous (n = 17) 12-week plant-based nutrition program received restaurant vouchers. Class satisfaction data were collected weekly.

Multiple ammonia-induced episodes of hepatic encephalopathy provoke neuronal cell loss in bile-duct ligated rats.

Background & Aims: Hepatic encephalopathy (HE) is defined as a reversible syndrome and therefore should resolve following liver transplantation (LT). However, neurological complications have been reported in up to 47% of LT recipients, which have been documented to be associated with a history of overt HE pre-LT. We hypothesise that multiple episodes of HE lead to permanent cell injury and exacerbate neurological dysfunction.

Ulcerative Colitis Is Associated With Diet-related Inflammation and Physical Activity in the IBD Partners E-cohort.

Background: Individuals with ulcerative colitis (UC) seek complementary treatment methods, including diet and physical activity, to manage the burden of living with UC. This study examined associations between diet-associated inflammation, physical activity (PA), and UC-related health outcomes.

Methods: Data were obtained from 2052 IBD Partners e-cohort participants with UC.

Flow cytometric isolation of drug-like conformational antibodies specific for amyloid fibrils.

Antibodies that recognize specific protein conformational states are broadly important for research, diagnostic and therapeutic applications, yet they are difficult to generate in a predictable and systematic manner using either immunization or antibody display methods. This problem is particularly severe for conformational antibodies that recognize insoluble antigens such as amyloid fibrils associated with many neurodegenerative disorders. Here we report a quantitative fluorescence-activated cell sorting (FACS) method for directly selecting high-quality conformational antibodies against different types of insoluble (amyloid fibril) antigens using a single, off-the-shelf human library.

Extracellular Vesicles in Chronic Lymphocytic Leukemia: Tumor Microenvironment Messengers as a Basis for New Targeted Therapies?

In addition to intrinsic genomic and nongenomic alterations, tumor progression is also dependent on the tumor microenvironment (TME, mainly composed of the extracellular matrix (ECM), secreted factors, and bystander immune and stromal cells). In chronic lymphocytic leukemia (CLL), B cells have a defect in cell death; contact with the TME in secondary lymphoid organs dramatically increases the B cells' survival via the activation of various molecular pathways, including the B cell receptor and CD40 signaling. Conversely, CLL cells increase the permissiveness of the TME by inducing changes in the ECM, secreted factors, and bystander cells.

Independent Effects of HIV and Antiretroviral Therapy on the Oral Microbiome Identified by Multivariate Analyses.

The oral microbiome is an important predictor of health and disease. We recently reported significant yet modest effects of HIV under highly active antiretroviral therapy (ART) on the oral microbiome (bacterial and fungal) in a large cohort of HIV-positive (HIV) and matched HIV-negative (HIV) individuals. As it was unclear whether ART added to or masked further effects of HIV on the oral microbiome, the present study aimed to analyze the effects of HIV and ART independently, which also included HIV subjects on preexposure prophylaxis (PrEP) therapy.

The effect of warming on seagrass wasting disease depends on host genotypic identity and diversity.

Temperature increases due to climate change have affected the distribution and severity of diseases in natural systems, causing outbreaks that can destroy host populations. Host identity, diversity, and the associated microbiome can affect host responses to both infection and temperature, but little is known about how they could function as important mediators of disease in altered thermal environments. We conducted an 8-week warming experiment to test the independent and interactive effects of warming, host genotypic identity, and host genotypic diversity on the prevalence and intensity of infections of seagrass (Zostera marina) by the wasting disease parasite (Labyrinthula zosterae).

Detecting clonemate pairs in multicellular diploid clonal species based on a shared heterozygosity index.

Clonal reproduction, the formation of nearly identical individuals via mitosis in the absence of genetic recombination, is a very common reproductive mode across plants, fungi and animals. To detect clonal genetic structure, genetic similarity indices based on shared alleles are widely used, such as the Jaccard index, or identity by state. Here we propose a new pairwise genetic similarity index, the SH index, based on segregating genetic marker loci (typically single nucleotide polymorphisms) that are identically heterozygous for pairs of samples (N ).

Impact of current Australian paid parental leave on families of preterm and sick infants.

Aim: Parents of preterm or sick infants are at increased risk of mental health problems. The financial stress associated with an infant's prolonged hospital stay can have an additional negative effect on families' wellbeing and child development. This study explores parent use of Australian paid parental leave (PPL) and the financial impact of having an infant requiring neonatal care.

Predictable Changes in Eelgrass Microbiomes with Increasing Wasting Disease Prevalence across 23° Latitude in the Northeastern Pacific.

Predicting outcomes of marine disease outbreaks presents a challenge in the face of both global and local stressors. Host-associated microbiomes may play important roles in disease dynamics but remain understudied in marine ecosystems. Host-pathogen-microbiome interactions can vary across host ranges, gradients of disease, and temperature; studying these relationships may aid our ability to forecast disease dynamics.

Management of Periprosthetic Polyvinyl Alcohol Synthetic Cartilage Implant Infection with Staged First Metatarsophalangeal Joint Arthrodesis.

Surgical management of hallux rigidus using a polyvinyl alcohol synthetic cartilage implant has gained popularity among foot and ankle surgeons. Although uncommon, appropriate diagnosis and management of a periprosthetic implant infection is critical in limiting morbidity. We present a case report and staged technique for converting a first metatarsal synthetic cartilage hemiarthroplasty to arthrodesis in the setting of a periprosthetic joint infection.

Coronal Hindfoot Alignment in Midfoot Charcot Neuroarthropathy.

Coronal plane hindfoot malalignment produces abnormal compensatory forces within the midfoot and forefoot. The primary aim of this study is to compare radiographic hindfoot alignment in patients with a midfoot Charcot event, and identify patterns associated with breakdown. A retrospective review of 43 patients (48 limbs) with midfoot Charcot neuroarthropathy were compared between the coronal hindfoot alignments and Charcot joint involvement.

Landscapes and bacterial signatures of mucosa-associated intestinal microbiota in Chilean and Spanish patients with inflammatory bowel disease.

Inflammatory bowel diseases (IBDs), which include ulcerative colitis (UC) and Crohn's disease (CD), cause chronic inflammation of the gut, affecting millions of people worldwide. IBDs have been frequently associated with an alteration of the gut microbiota, termed dysbiosis, which is generally characterized by an increase in abundance of Proteobacteria such as , and a decrease in abundance of Firmicutes such as (an indicator of a healthy colonic microbiota). The mechanisms behind the development of IBDs and dysbiosis are incompletely understood.

Indicator species characterization and removal in a detention pond in the Plaster Creek watershed.

Microbial pathogen contamination is a leading cause of impairment for urban rivers and streams in Michigan. Reports on the ability of green infrastructure best management practices to remove microbial pathogens have been highly variable. This study evaluated the influence of a detention basin (Kreiser Pond) on microbial dynamics in the Plaster Creek watershed in West Michigan.

Experiences of midlife and older African American men living with type 2 diabetes.

Objective: Type 2 Diabetes Mellitus (T2DM) is a complicated disease that disproportionately affects African American men. Understanding the experiences of African American men living with T2DM is important for developing effective, culturally sensitive interventions. The purpose of this study was to describe how African American men view their T2DM and describe their perspectives on living with and self-managing T2DM.

Wintering Snow Buntings Elevate Cold Hardiness to Extreme Levels but Show No Changes in Maintenance Costs.

AbstractResident temperate passerines adjust their phenotypes to cope with winter constraints, with peak performance in metabolic traits typically occurring during the coldest months. However, it is sparsely known whether cold-adapted northern species make similar adjustments when faced with variable seasonal environments. Life in near-constant cold could be associated with limited flexibility in traits underlying cold endurance.

Previous exposure mediates the response of eelgrass to future warming via clonal transgenerational plasticity.

Mortality and shifts in species distributions are among the most obvious consequences of extreme climatic events. However, the sublethal effects of an extreme event can have persistent impacts throughout an individual's lifetime and into future generations via within-generation and transgenerational phenotypic plasticity. These changes can either confer resilience or increase susceptibility to subsequent stressful events, with impacts on population, community, and potentially ecosystem processes.

The effects of exercise on cancer-related fatigue in breast cancer patients during primary treatment: a meta-analysis and systematic review.

Introduction: Cancer-related fatigue is one of the most prevalent symptoms reported by breast cancer survivors. Despite a corpus of literature dedicated to understanding and identifying evidence-based treatments for cancer-related fatigue, gaps in the literature remain, particularly for breast cancer survivors during their primary treatment. Exercise training may represent an efficacious behavioral modality for mitigating fatigue symptoms in cancer survivors; yet, the effects of exercise during adjuvant therapy is an understudied area.
