Regulatory T cell expansion prevents retinal degeneration in type 2 diabetes.

Background: The global incidence of type 2 diabetes (T2D) is rapidly increasing, with retinopathy being its most common complication and a leading cause of preventable blindness. Although the precise mechanisms involved in the development of diabetic retinopathy (DR) are not fully understood, defective immunomodulation is a recognized key factor in its pathophysiology. Regulatory T cells (Treg) regulate inflammation and promote regeneration, and while they are known to have important anti-inflammatory and neuroprotective roles in other tissues, including central nervous system, their role in the diabetic retina remains largely unknown.

Sitagliptin eye drops prevent the impairment of retinal neurovascular unit in the new Trpv2 rat model.

Impaired function of the retinal neurovascular unit (NVU) is an early event in diabetic retinopathy (DR). It has been previously shown that topical delivery of the dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin can protect against diabetes-mediated dysfunction of the retinal NVU in the db/db mouse. The aim of the present study was to examine whether sitagliptin could prevent the DR-like lesions within the NVU of the new non-diabetic model of DR, the Trpv2 knockout rat (Trpv2).

Marine emissions of methanethiol increase aerosol cooling in the Southern Ocean.

Ocean-emitted dimethyl sulfide (DMS) is a major source of climate-cooling aerosols. However, most of the marine biogenic sulfur cycling is not routed to DMS but to methanethiol (MeSH), another volatile whose reactivity has hitherto hampered measurements. Therefore, the global emissions and climate impact of MeSH remain unexplored.

Non-Surgical Approaches to the Management of the Intrathoracic Goiter-A Systematic Review.

Background: Intrathoracic goiters (ITGs) are usually managed by surgical excision, However, over recent years, non-surgical strategies are emerging as an alternatives for treating this condition.

Methods: A systematic review of research published since 2017 in the PubMed database was conducted and a total of 39 articles were retrieved, along with methodological issues and future directions in the research on ITGs.

Results: Several non-surgical treatments exist, including radio-iodine ablation (RIA) and mini-invasive approaches, such as transcervical microwave ablation (TcMA), transcervical radiofrequency ablation (TcRfA), or selective embolization of the thyroid arteries (SETA).

SMART DIABETES HOSPITAL: CLINICAL IMPACT IN COMPLEX SURGICAL UNITS OF A TERTIARY HOSPITAL.

Aim: To evaluate the impact of a proactive action of a specialized diabetes team (SDT) on different health outcomes in patients hospitalized in high complexity surgery units, including solid organ transplant surgical units, of a tertiary hospital.

Methods: Nested case control study matched (1:1) by age and gender. The control group consisted of patients (n = 120) who were under the standard of care diabetes management admitted three months' prior the cases.
