Background: Enhanced neural plasticity early after stroke suggests the potential to improve outcomes with intensive rehabilitation therapy. Most patients do not get such therapy, however, due to limited access, changing rehabilitation therapy settings, low therapy doses, and poor compliance.

Objective: To examine the feasibility, safety, and potential efficacy of an established telerehabilitation (TR) program after stroke initiated during admission to an inpatient rehabilitation facility (IRF) and completed in the patient's home.

Autoimmune diseases are caused by adaptive immune responses to self-antigens. The development of antigen-specific therapies that suppress disease-related, but not unrelated immune responses in general, is an important goal of biomedical research. We have previously shown that delivery of myelin peptides to liver sinusoidal endothelial cells (LSECs) using LSEC-targeting nanoparticles provides effective protection from CD4 T-cell-driven autoimmune encephalomyelitis.

Background & Aims: IL-17A-producing T cells are present in autoimmune cholestatic liver diseases; however, little is known about the contribution of IL-17 to periductal immune responses. Herein, we investigated the role of IL-17 produced by antigen-specific CD8 T cells in a mouse model of cholangitis and in vitro in human cholangiocyte organoids.

Methods: K14-OVAp mice express a major histocompatibility complex I-restricted ovalbumin (OVA) peptide sequence (SIINFEKL) on cholangiocytes.

Background And Aims: T cells from patients with primary sclerosing cholangitis (PSC) show a prominent interleukin (IL)-17 response upon stimulation with bacteria or fungi, yet the reasons for this dominant T-helper 17 (Th17) response in PSC are not clear. Here, we analyzed the potential role of monocytes in microbial recognition and in skewing the T-cell response toward Th17.

Approach And Results: Monocytes and T cells from blood and livers of PSC patients and controls were analyzed ex vivo and in vitro using transwell experiments with cholangiocytes.

Background & Aims: T cells are central mediators of liver inflammation and represent potential treatment targets in cholestatic liver disease. Whereas emerging evidence shows that bile acids (BAs) affect T cell function, the role of T cells for the regulation of BA metabolism is unknown. In order to understand this interplay, we investigated the influence of T cells on BA metabolism in a novel mouse model of cholangitis.

Background: Intestinal fibrosis is a common and serious complication of Crohn's disease characterized by the accumulation of fibroblasts, deposition of extracellular matrix, and formation of scar tissue. Although many factors including cytokines and proteases contribute to the development of intestinal fibrosis, the initiating mechanisms and the complex interplay between these factors remain unclear.

Methods: Chronic infection of mice with Salmonella enterica serovar Typhimurium was used to induce intestinal fibrosis.

The pathogenesis of the progressive liver disease, primary sclerosing cholangitis (PSC), remains largely elusive. The strong genetic association with HLA loci suggests that T cell-dependent, adaptive immune reactions could contribute to disease pathogenesis. Recent studies have indicated that PSC is also associated with polymorphisms in the locus encoding for proapoptotic Bim (BCL2L11).

Most diabetes is polygenic in etiology, with (type 1 diabetes, T1DM) or without (type 2 diabetes, T2DM) an autoimmune basis. Genetic counseling for diabetes generally focuses on providing empiric risk information based on family history and/or the effects of maternal hyperglycemia on pregnancy outcome. An estimated one to five percent of diabetes is monogenic in nature, e.

A total of 232 samples of corn commercialised in Santa Catarina state, Southern Brazil (temperate zone climate), were evaluated from 2007 to 2012 for fumonisins (FBs: FB1 and FB2). Before performing this study, a FBs method with liquid chromatography and fluorescence detection (ex. 335; em.

The aim of this study was to examine the dose-response relationship between walking activity and physical function (PF) in community-dwelling older adults. Physical activity (PA, pedometry) and PF (self-report [SF-36] and 6-minute walk test [6MWT]) were assessed in 836 individuals. Accumulated PA was categorized into four groups (1 = ≤ 2,500; 2 = 2,501-5,000; 3 = 5,001-7,500; and 4 = ≥ 7,501 steps/day).

Type 2 diabetes mellitus (T2DM) accounts for 90%-95% of all diabetes cases. The overarching goal in caring for patients with T2DM is to prevent microvascular and macrovascular complications with glycemic control. Several studies such as UKPDS, DCCT, and EDIC have been performed to evaluate the effects of glucose control on tissue complications in patients with diabetes.

Context: Although primary thyroid lymphoma is a rare cause of both thyroid malignancy and extranodal lymphoma, awareness of this disease is important in order to achieve an early diagnosis and implement treatment. We review the epidemiology, clinical presentation, diagnosis, and treatment of this rare disorder.

Evidence Acquisition: This review is based on a search of PubMed and MDConsult for English language articles containing the term "primary thyroid lymphoma.

Introduction: Additional oral antidiabetic agents to metformin, sulfonylureas (SU) and thiazolidinediones (TZD) are approved for the treatment of type 2 diabetes.

Areas Covered: The efficacy and safety of metformin, SUs, TZDs, dipeptidyl peptidase-IV (DPP-4) inhibitors, meglitinide analogs, α-glucosidase inhibitors (AGIs), bile-acid sequestrants (BAS) and bromocriptine will be reviewed.

Expert Opinion: Several new oral agents have been approved for type 2 diabetes management in recent years.

Background: Adolescents are developmentally in a period of transition-from children cared for by their parents to young adults capable of self-care, independent judgment, and self-directed problem solving. We wished to develop a behavioral contract for adolescent diabetes management that addresses some negotiable points of conflict within the parent-child relationship regarding self-monitoring and then assess its effectiveness in a pilot study as part of a novel cell phone-based glucose monitoring system.

Methods: In the first phase of this study we used semistructured interview techniques to determine the major sources of diabetes-related conflict in the adolescent-parent relationship, to identify factors that could facilitate or inhibit control, and to determine reasonable goals and expectations.

Purpose: To assess the feasibility and acceptability of a cell phone glucose monitoring system for adolescents with type 1 diabetes and their parents.

Methods: The authors recruited patients with type 1 diabetes who had been diagnosed for at least 1 year.

The pros and cons of population screening for thyroid disease have been hotly debated over the past several decades. This article addresses the issue from the point of view of the potential benefit of screening, that is, disease detection. Earlier diagnoses of hypothyroidism, hyperthyroidism, thyroid nodules, thyroid cancer and so on, with implementation of the indicated diagnostic and therapeutic interventions, avoid the adverse consequences of unrecognized and untreated progressive disease.

The new gold standard has evolved from aging in place to aging in community. Having social capital by being an active member of a community has a positive effect and can decrease vulnerability to health risk. Federal and state monies have been utilized to support community activities for the elderly including the first meal programs and moving to community-based assisted living programs.
