In severe hypoxia, homeostatic mechanisms maintain function of the brainstem respiratory network. We hypothesized that hypoxia involves a transition from neuronal mechanisms of normal breathing (eupnea) to a rudimentary pattern of inspiratory movements (gasping). We provide evidence for hypoxia-driven transformation within the central respiratory oscillator, in which gasping relies on persistent sodium current, whereas eupnea does not depend on this cellular mechanism.

Chronic wounds represent a persistent clinical challenge due to prolonged inflammation and impaired tissue repair mechanisms. Cannabidiol (CBD), recognized for its anti-inflammatory and pro-healing properties, shows therapeutic promise in wound care. However, its delivery via lipid nanoparticles (LNPs) remains challenging due to CBD's inherent instability and low bioavailability.

Chronic Fatigue Syndrome (CFS) is a complex disorder characterized by prolonged, unexplained fatigue and challenging diagnosis. We report the case of a 35-year-old Japanese woman with CFS who had experienced chronic fatigue since the age of 11 years. Despite treatment with modafinil, methylphenidate, levocarnitine, and ubiquinone, the symptoms persisted.

The COORDINATE-Diabetes randomized clincal trial evaluated a multi-faceted intervention to increase the use of evidence-based therapies for reducing cardiovascular risk among participants with diabetes and atherosclerotic cardiovascular disease. This analysis reports the discontinuation rate of SGLT-2i and GLP-1RA in follow up and summarises the clinician-reported reasons underlying these decisions.

Vascular malformations (VMs) are congenital abnormalities of blood or lymphatic vessels, present at birth and growing proportionally with the individual. They are classified into types such as capillary, venous, lymphatic, and arteriovenous malformation (AVMs). Symptoms include discoloration, swelling, pain, or functional impairment, depending on the type and location.

Aquagenic syringeal acrokeratoderma (ASA) is a rare dermatological condition characterized by the transient appearance of edematous, white, translucent papules on the palms following water exposure. While the condition is most commonly associated with cystic fibrosis (CF) and predominantly affects young women, this report presents a unique case in a 24-year-old man without a history of cystic fibrosis. The patient reported a 10-month history of painful, pruritic eruptions on the hands following exposure to water.
