BACKGROUND: Ewing sarcoma survivors (ESSs) are at increased risk for treatment-related complications. The incidence of treatment-related morbidity and late mortality with aging is unknown. METHODS: This study reports survival probabilities, estimated with the Kaplan-Meier method, and the cumulative incidence of cause-specific mortality and chronic conditions among ESSs in the Childhood Cancer Survivor Study who were treated between 1970 and 1986. Piecewise exponential models were used to estimate relative rates (RRs) and 95% confidence intervals (CIs) for these outcomes...

Stress elicits neuroendocrine, autonomic and behavioral responses that mitigate homeostatic imbalance and ensure survival; however, chronic engagement of such responses promotes psychological, cardiovascular and metabolic impairments. Over recent years, the renin-angiotensin system has emerged as a key mediator of stress responding and its related pathologies, but the neuronal circuits that orchestrate these interactions are not known. These studies combine the use of the Cre-recombinase/loxP system in mice with optogenetics to structurally and functionally characterize angiotensin type-1a receptor-containing neurons of the paraventricular nucleus of the hypothalamus, the goal being to determine the extent of their involvement in the regulation of stress responses...

Omalizumab is very effective in the majority of patients with severe chronic spontaneous urticaria (CSU), but its mechanism of action is still unclear. In CSU the coagulation cascade is activated with an intensity that parallels the disease severity, and elevated plasma D-dimer levels are associated with a poor response to both antihistamines and cyclosporin. We measured D-dimer plasma levels before and after the first administration of omalizumab in 32 patients with severe CSU. A number of clinical and laboratory parameters were recorded, including the urticaria activity score, presence of angioedema, disease duration, C-reactive protein, anti-nuclear, and anti-thyroid antibodies...

In this study, the combined effect of doxorubicin with cucurbitacin B on survival of anaplastic thyroid carcinoma cells was evaluated. For experiments, 8505C and CAL62 human anaplastic thyroid carcinoma cells were used. Cell viability, the percentage of viable cells, and cytotoxic activity were measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, multiplexed cytotoxicity assay, and cytotoxicity assay, respectively. Reactive oxygen species production was measured. In experiments, doxorubicin and cucurbitacin B reduced cell viability in a dose- and time-dependent manner...

BACKGROUND: Current information indicates that psoriasis is a metabolic disorder with systemic manifestations. Reports have revealed an association between psoriasis and several chronic autoimmune disorders. For one of these disorders, Hashimoto's thyroiditis (HT), there are scarce, and relatively unconfirmed, reports of an association with psoriasis. We sought to determine if such an association is detectable in a large medical record data repository. METHODS: We searched one institution's electronic medical record data repository from January 2010 to December 2013...

Increased incidence of C-cell carcinogenicity has been observed for glucagon-like-protein-1 receptor (GLP-1r) agonists in rodents. It is suggested that the duration of exposure is an indicator of carcinogenic potential in rodents of the different products on the market. Furthermore, the role of GLP-1-related mechanisms in the induction of C-cell carcinogenicity has gained increased attention by regulatory agencies. This study proposes an integrative pharmacokinetic/pharmacodynamic (PKPD) framework to identify explanatory factors and characterize differences in carcinogenic potential of the GLP-1r agonist products...

INTRODUCTION: For late-life neurocognitive disorders, as for other late-life chronic diseases, much recent interest has focused on the possible relevance of Developmental Origins of Health and Disease (DOHaD). Programming by undernutrition in utero, followed by overnutrition in adult life may lead to an increased risk, possibly mediated through cardiovascular and metabolic pathways. This study will specifically examine, if lower birth weight is associated with poorer cognitive functioning in late life in a south Indian population...

The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities...

BACKGROUND: Chronic spontaneous urticaria (CSU) may be associated with autoimmune thyroid diseases, and the Autologous Serum Skin Test (ASST) is an autoreactivity marker. The thyrotropin (TSH) and TSH receptor (TSHR) could play a role in the pathogenesis of CSU. The aim of this study was to evaluate ASST positivity and TSHR gene expression in healthy skin and ASST wheals in euthyroid women with CSU, with (14 patients) and without (15 patients) Hashimoto's thyroiditis (HT). METHODS: ASST was performed and TSHR gene expression studied in wheals induced by ASST and in healthy skin...

BACKGROUND Ankylosing spondylitis (AS) is a chronic inflammatory disease that predominantly affects the axial skeleton. The ability of anti-TNF-α agents to reduce disease activity in patients with axial spondyloarthritis (axSpA), including AS, has been demonstrated in multiple randomized trials and several meta-analyses. Reports on the efficacy of rituximab in treatment of AS have described good results. We report on a patient with AS who failed anti-TNF-α therapy but showed good clinical improvement with rituximab therapy...

Fibromyalgia (FM) is a syndrome characterised by chronic musculoskeletal pain, tenderness and other somatic symptoms. The prevalence of FM is approximately 2-7% in the general global population and is 30-40% in the population of Hashimoto thyroiditis (HT) with a structural pathology. In 2010, new classification criteria for FM were proposed, as an alternative to the American College of Rheumatology (ACR) 1990 criteria. The objectives of the present study were to identify the prevalence of FM in the HT population and evaluate the associated features by using the new diagnostic criteria...

Higher resting heart rate (RHR) is associated with increased risk of all-cause and cardiovascular mortality, with some reports showing the magnitude of association with all-cause mortality being stronger than that with cardiovascular mortality. This suggests that RHR association with mortality may not be limited to cardiovascular death. We compared the association between RHR with cardiovascular and noncardiovascular mortality in 6,743 participants (mean age 58.7 years, 52% women, 48% non-Hispanic whites) from the Third National Health and Nutrition Examination Survey (NHANES-III) after excluding those on antiarrhythmic drugs or with missing data...

OBJECTIVES: Current preoperative diagnosis of thyroid nodules remains imperfect despite recent advances in cytopathology and molecular diagnostics. False-positivity in preoperative fine needle aspiration cytology (FNAC) may lead to overtreatment of patients, including total thyroidectomy, and sometimes to lawsuits for misdiagnosis and malpractice. In this study, we analyzed clinical characteristics and pathologic findings in patients with false-positivity for papillary thyroid carcinoma (PTC) in FNAC...

Illness induces major modifications in central and peripheral thyroid hormone (TH) metabolism, so-called nonthyroidal illness syndrome (NTIS). As a result, organ specific changes in local TH availability occur depending on the type and severity of illness. Local TH availability is of importance for the regulation of the tissue specific TH target genes and determined by the interplay between deiodinating enzymes, TH transport and TH receptor (TR) expression. In the present study we evaluated changes in TH transport, deiodination, and TR expression, the resulting tissue TH concentrations and the expression of TH target genes in liver and muscle in three animal models of illness...

Hashimoto's thyroiditis (HT) is a chronic inflammation of the thyroid gland and is known as the most common autoimmune disease. Development of autoimmune destruction of thyroid cells is a multi-step process involving convergence of genetic and environmental factors. Cytotoxic T-lymphocyte antigen-4 (CTLA-4) has an important role in homeostasis and negative regulation of immune responses, and is therefore considered to be a key element in the development of autoimmune diseases. The present study evaluated the association of the CTLA-4 gene polymorphisms 318C/T (rs5742909) and +49A/G (rs231775) with HT in an Iranian population (including 82 patients with HT and 104 healthy controls who were referred for routine premarital blood screenings)...

The thyrotropin receptor (TSHR) gene has been defined as a highly mutable gene. Mutations in the TSHR gene result in either gain or loss of the receptor function. Subclinical hypothyroidism (SH) is a clinical condition defined as an elevated serum TSH level associated with normal free thyroxine and free triiodothyronine. Chronic autoimmune thyroiditis is the most frequent cause of subclinical hypothyroidism in adults. In rare cases, a loss-of-function mutation of TSHR is the cause of SH. In the present study, a novel TSHR mutation (V87L; confirmed to be a loss-of-function mutation) was identified in a 59-year-old Chinese woman, as the potential cause of the patient's subclinical hypothyroidism...
