Diabetes mellitus is a prevalent chronic disease that significantly impacts patients' quality of life and leads to serious complications, making effective blood glucose management essential. Current methods primarily include invasive fingertip blood testing and minimally invasive continuous glucose monitoring; however, the former presents psychological and infection risks, while the latter is costly and complex. Here, we report a phase separation-based porous microneedle-based analysis system, featuring a sampling module and a detection module, for point-of-care dermal interstitial fluid (DISF) glucose testing in a non-invasive, cost-effective and user-friendly manner. The accuracy and reliability of the proposed system have been thoroughly assessed through in vitro and on-body tests. Specifically, on-body trials with nine subjects during an oral glucose tolerance test (OGTT) confirmed consistent fluctuations between DISF and blood glucose concentrations, while routine tests among five volunteers (three healthy individuals and two patients with prediabetes) showed excellent capability of the proposed system for blood glucose prediction in a user-friendly and non-invasive manner. We believe this approach offers a promising, user-friendly solution for home-based, non-invasive, and rapid blood glucose management.

The adverse effects of Western diets (WD), high in both fat and simple sugars, which contribute to obesity and related disorders, have been extensively studied in laboratory rodents, but not in non-laboratory animals, which limits the scope of conclusions. Unlike laboratory mice or rats, non-laboratory rodents that reduce body mass for winter do not become obese when fed a high-fat diet. However, it is not known whether these rodents are also resistant to the adverse effects of WD.

Major depressive disorder is a prevalent and debilitating psychiatric illness that produces significant disability. Clinical data suggest that the pathophysiology of depression is due, in part, to a dysregulation of inflammation and glutamate levels in the brain. The systemic administration of lipopolysaccharide (LPS) has been shown to induce depressive-like behaviors in mice.

Chronic kidney disease (CKD), heart failure (HF) and atherosclerotic cardiovascular disease (ASCVD) are pathologies that may remain silent for a long time and thus are largely underdiagnosed in clinical practice. The use of biomarkers may help detect people already suffering from these diseases at an early stage or at increased risk to develop them in a near future. The aim of this article is to discuss the place of the assays of albuminuria, natriuretic peptide (BNP/proBNP) and high-sensitivity troponin as well as lipoprotein(a) to help in the diagnosis and prognosis assessment of individuals at risk of presenting or developing a CKD, HF or ASCVD.

Type 1 diabetes (T1D) is an autoimmune chronic disease that leads to the destruction of pancreatic beta cells and thus requires lifelong insulin therapy. Constraints and adverse events associated to insulin therapy are well known as well as the risk of long-term complications linked to chronic hyperglycaemia. Symptomatic T1D is preceded by a preclinical asymptomatic period, which is characterized by the presence of at least two auto-antibodies against beta cell without disturbances of blood glucose control (stage 1) or, in addition to immunological biomarkers, by the presence of mild dysglycaemia reflecting a defect of early insulin secretion (stage 2).

Background: The susceptibility values of the basal ganglia reflect the health status of these nuclei. We aimed to explore the associations between various demographic characteristics, lifestyle factors, and biological factors that have the potential to contribute to magnetic susceptibility and investigate the comprehensive impact of these multiple factors on basal ganglia susceptibility values.
Methods: We included 25,980 participants from the UK Biobank.
