Article Synopsis
  • Autoantibodies against IFN-α (AAb-IFN-α) may be linked to less aggressive autoimmune behaviors in latent autoimmune diabetes in adults (LADA) compared to early-onset type 1 diabetes (T1D).
  • Researchers compared the presence of AAb-IFN-α in LADA (41 subjects) versus T1D (90 subjects) to determine its clinical significance.
  • Results indicated a higher positivity for AAb-IFN-α isoforms in LADA patients, suggesting a unique autoimmune profile that could inform future therapeutic approaches in autoimmune diseases.

Article Synopsis
  • Diabetic nephropathy is a major cause of kidney disease in developed countries, and this study aimed to compare the effects of glucagon-like peptide-1 receptor agonists (GLP1RA) and sodium-glucose cotransporter 2 inhibitors (SGLT2i) on kidney function in patients with type 2 diabetes mellitus.
  • A total of 478 patients were analyzed, and results showed that the reduction in estimated glomerular filtration rate (eGFR) after 24 months was similar for both treatments, with no significant differences in weight loss or treatment discontinuation.
  • The findings suggest that both classes of medication have similar effects on kidney function over time, indicating their potential for managing diabetic nephropathy effectively.

Chitotriosidase (CHIT), a mammalian chitinase secreted by neutrophils and activated macrophages, is increased in both cardiovascular disease (CVD) and type 2 diabetes (T2D). Arterial stiffness rises early in T2D and increases the risk of CVD. The aim of this study is to evaluate CHIT activity as an early biomarker of arterial stiffness in people with T2D free from overt vascular complications.

We describe a proof-of-principle experiment aiming to investigate the inverse-square law of gravitation at the centimeter scale. The sensor is a two-stage torsion pendulum, while actuation is accomplished by a variable liquid mass. The time-varying gravitational force is related to the level of the circulating fluid in one or two containers at a short distance from the test mass, with all moving mechanical parts positioned at a large distance.

Unraveling the immune signatures in rheumatoid arthritis (RA) patients receiving various treatment regimens can aid in comprehending the immune mechanisms' role in treatment efficacy and side effects. Given the critical role of cellular immunity in RA pathogenesis, we sought to identify T-cell profiles characterizing RA patients under specific treatments. We compared 75 immunophenotypic and biochemical variables in healthy donors (HD) and RA patients, including those receiving different treatments as well as treatment-free patients.

The range of vaccines developed against severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) provides a unique opportunity to study immunization across different platforms. In a single-center cohort, we analyzed the humoral and cellular immune compartments following five coronavirus disease 2019 (COVID-19) vaccines spanning three technologies (adenoviral, mRNA and inactivated virus) administered in 16 combinations. For adenoviral and inactivated-virus vaccines, heterologous combinations were generally more immunogenic compared to homologous regimens.

Article Synopsis
  • Patients with diabetic polyneuropathy and pain often experience a loss of sensory function, raising questions about how pain is generated despite reduced nerve input.
  • A study involving 93 patients found that those with painful diabetic neuropathy had impaired spinal reflex responses, which suggests a mechanism called spinal disinhibition may be involved in their pain sensations.
  • The research linked greater spinal disinhibition to increased sensitivity to mechanical pain and heightened burning sensations, indicating a unique pain profile that combines loss and gain of sensory function.

Article Synopsis
  • The study investigates the role of biomarkers osteocalcin, osteoprotegerin, and osteopontin in identifying cardiovascular disease (CVD) and diabetic retinopathy (DR) in individuals with type 2 diabetes (T2D).
  • It involved measuring the concentrations of these biomarkers in 848 T2D participants and using logistic regression to analyze their associations with CVD and DR.
  • The findings indicate that higher osteocalcin levels are linked to macrovascular complications (CVD), while increased osteoprotegerin and osteopontin levels are associated with microvascular complications (DR), suggesting these proteins are key players in vascular disease processes in diabetes.

B cells, follicular helper T (Tfh) cells and follicular regulatory T (Tfr) cells are part of a circuit that may play a role in the development or progression of rheumatoid arthritis (RA). With the aim of providing further insight into this topic, here we evaluated the frequency of different subsets of Tfh and Tfr in untreated and long-term treated RA patients from a cohort of Argentina, and their potential association with particular human leukocyte antigen (HLA) class-II variants and disease activity. We observed that the frequency of total Tfh cells as well as of particular Tfh subsets and Tfr cells were increased in seropositive untreated RA patients.

Sodium−glucose co-transporter-2 inhibitors or gliflozins, the newest anti-hyperglycemic class, induce cardioprotective benefits in patients with type 2 diabetes (T2D). As platelet activation and oxidative stress play a key role in atherothrombotic-related complications, we hypothesized that gliflozins might modulate oxidative stress, platelet activation and thrombus formation. We performed an interventional open-label single-arm before-after study in 32 T2D patients on top of their ongoing metformin therapy.

  • The study investigates compact binary coalescences with at least one component mass between 0.2 and 1.0 solar masses using data from Advanced LIGO and Advanced Virgo detectors over six months in 2019, but they found no significant gravitational wave candidates.
  • The analysis leads to an upper limit on the merger rate of subsolar binaries ranging from 220 to 24,200 Gpc⁻³ yr⁻¹, based on the detected signals’ false alarm rate.
  • The researchers use these limits to set new constraints on two models for subsolar-mass compact objects: primordial black holes (suggesting they make up less than 6% of dark matter) and
