Association between thyroid dysfunction and insulin resistance: a retrospective cohort study.

Objective: To evaluate the association between thyroid disease and diabetes markers.

Design: Retrospective cohort study.

Setting: The study was conducted in a diagnostic setting where the primary care providers recommended the patients to test for thyroid and diabetes panels.

Significance of Anti-TPO as an Early Predictive Marker in Thyroid Disease.

Even though most thyroid subjects are undiagnosed due to nonspecific symptoms, universal screening for thyroid disease is not recommended for the general population. In this study, our motive is to showcase the early appearance of thyroid autoantibody, anti-TPO, prior to the onset of thyroid hormone disruption; hence the addition of anti-TPO in conjunction with traditional thyroid markers TSH and FT4 would aid to reduce the long-term morbidity and associated health concerns. Here, a total of 4581 subjects were tested multiple times for TSH, FT4, anti-TPO, and anti-Tg and followed up for 2 years.

Exploring Systemic Autoimmunity in Thyroid Disease Subjects.

Introduction: Individuals with one autoimmune disease are at risk of developing a second autoimmune disease, but the pathogenesis or the sequential occurrence of multiple autoimmune diseases has not been established yet. In this study, we explored the association and sequential occurrence of antibodies in thyroid disease and systemic autoimmune disease subjects. We evaluated thyroid hormones, thyroid-stimulating hormone (TSH), free thyroxine (FT4), thyroid autoantibodies, anti-thyroperoxidase (anti-TPO), and anti-thyroglobulin (Tg) to comprehend the association with systemic autoimmune autoantibodies, anti-nuclear antibodies (ANA), and autoantibodies to extractable nuclear antigens (ENA) in subjects with thyroid-related symptoms.

Insights into cardiovascular risk and nutritional status in subjects with wheat-related disorders.

Wheat-related disorders are a spectrum of disorders associated with different autoimmune and non-autoimmune diseases. However, it is unclear whether these wheat-related disorders lead to adverse health effects such as cardiovascular risk, nutritional deficiencies etc. The objective of the study was to explore the lipid profiles and the nutritional status of subjects with wheat-related disorders to understand the potential threat of wheat on cardiovascular risk and nutritional deficiency.

Analysis of Electrochemically Elusive Trace Metals with Carbon Fiber Microelectrodes.

There is great interest in rapidly monitoring metals of biological and environmental interest. Electrochemistry is traditionally a powerful tool for metal analysis but can be limited by its scope and low temporal resolution. The scope is limited by the potential window of the working electrode and rapid analysis is limited, in part, by the need for nucleation/growth for preconcentration.

Fast voltammetry of metals at carbon-fiber microelectrodes: towards an online speciation sensor.

Speciation controls the chemical behavior of trace metals. Thus, there is great demand for rapid speciation analysis in a variety of fields. In this study, we describe the application of fast scan cyclic voltammetry (FSCV) and fast scan adsorption controlled voltammetry (FSCAV) to trace metal speciation analysis.

Fast voltammetry of metals at carbon-fiber microelectrodes: rapid determination of solution formation constants.

Metal speciation controls the behavior of aqueous metal ions. Fundamental thermodynamic parameters, such as the formation constant (K) of metal-ligand equilibria, provide useful speciation information. Although this information can be determined by spectroscopic techniques with high accuracy, it comes at the expense of time and cost.

Voltammetric Characterization of Cu(II) Complexation in Real-Time.

Aqueous metal behavior is strongly regulated by speciation, which in turn is highly dependent on complexation. Trace metal complexation is difficult to characterize in dynamically changing systems due to a lack of analytical methods that can rapidly report free-metal concentrations. In this paper, we perform proof-of-principle experiments that demonstrate the utility of fast-scan cyclic voltammetry (FSCV) for providing speciation information in real-time by characterizing dynamic Cu(II) binding.

Real-time subsecond voltammetric analysis of Pb in aqueous environmental samples.

Lead (Pb) pollution is an important environmental and public health concern. Rapid Pb transport during stormwater runoff significantly impairs surface water quality. The ability to characterize and model Pb transport during these events is critical to mitigating its impact on the environment.
