Introduction: This analysis aimed to investigate diabetes-specific psychological outcomes among adults with type 1 diabetes (T1D) using hybrid closed-loop (HCL) versus standard therapy.
Research Design And Methods: In this multicenter, open-label, randomized, controlled, parallel-group clinical trial, adults with T1D were allocated to 26 weeks of HCL (MiniMed™ 670G) or standard therapy (insulin pump or multiple daily injections without real-time continuous glucose monitoring). Psychological outcomes (awareness and fear of hypoglycemia; and diabetes-specific positive well-being, diabetes distress, diabetes treatment satisfaction, and diabetes-specific quality of life (QoL)) were measured at enrollment, mid-trial and end-trial.
Obesity is a growing global health epidemic with limited orally administered therapeutics. Serotonin (5-HT) is one neurotransmitter which remains an excellent target for new weight-loss therapies, but a gap remains in understanding the mechanisms involved in 5-HT produced in the dorsal Raphe nucleus (DRN) and its involvement in meal initiation. Using an optogenetic feeding paradigm, we showed that the 5-HT➔arcuate nucleus (ARH) circuit plays a role in meal initiation.

Technology use is associated with better glycaemia, with the most advanced being automated insulin delivery (AID) systems, which are now recommended as gold-standard T1D care. Our Australian AID trial shows a wide spectrum of adults with T1D can achieve recommended targets.

Prolonged stressful stimuli can influence the stress response, mediated by the hypothalamic-pituitary-adrenal (HPA) axis. However, there is limited literature investigating HPA axis function in patients with cancer.

Summary: We describe and characterise the case of a 26-year-old female undergoing surgery for a right-sided sinonasal alveolar rhabdomyosarcoma who developed profound, transient arginine vasopressin deficiency (AVP-D, formerly central diabetes insipidus (DI)) associated with anaesthesia. In this case report, we characterise the development of AVP-D with serial copeptin and paired urine and serum osmolality measurements. Based on the anaesthetic agent's profile and the literature, we attribute this presentation to propofol exposure.

Estrogen receptor-α (ERα), classically known as a nuclear receptor, exists as a membrane-bound receptor to mediate this rapid action of E, but the ionic mechanisms remain unclear. Here, we show that a membrane channel protein, chloride intracellular channel protein-1 (Clic1), can physically interact with ERα with a preference to the membrane-bound ERα.

We present an investigation of the ultrafast dynamics of the polycyclic aromatic hydrocarbon fluorene initiated by an intense femtosecond near-infrared laser pulse (810 nm) and probed by a weak visible pulse (405 nm). Using a multichannel detection scheme (mass spectra, electron and ion velocity-map imaging), we provide a full disentanglement of the complex dynamics of the vibronically excited parent molecule, its excited ionic states, and fragments. We observed various channels resulting from the strong-field ionization regime.

Dysfunctions in this system, such as loss-of-function mutations in the Htr2c gene, can lead to hyperphagia and obesity. In this study, we aimed to investigate the potential therapeutic strategies for ameliorating hyperphagia, hyperglycemia, and obesity associated with a loss-of-function mutation in the Htr2c gene (Htr2cF327L/Y).

A new data analysis approach is introduced that considers the momentum partitioning between the fragments of the breakup of a molecular polycation to disentangle concurrent fragmentation channels, which yield the same ion species. We exploit this approach to examine the momentum exchange relationship between the products, which provides direct insight into the dynamics of molecular fragmentation.

The photoexcited molecules and eventual I atom products are probed by site-selective ionization at the I 4d edge using intense XUV pulses, which induce multiple charges initially localized to the iodine atom. At C-I separations below the critical distance for charge transfer (CT), charge can redistribute around the molecule leading to Coulomb explosion and charged fragments with high kinetic energy.

The pathophysiology of such deposition varies based on subtype, therefore treatment options vary not only in terms of severity of disease but also with subtype. This case report describes a 52-year-old female with systemic sclerosis and an extensive past medical history who initially presented with complaints of worsening left lower leg pain, a negative workup for deep vein thrombosis, and an extensive palpable mass in the posterior thigh with erythema, drainage, and purulence.

Few studies have evaluated the performance of flash glucose monitoring in hospitalized patients requiring intravenous insulin therapy. In this prospective study, an intravenous insulin infusion was adjusted hourly using flash glucose monitoring in hospitalized adults with prednisolone-associated hyperglycemia. The difference in paired point of care (POC) and flash glucose measurements and risk of severe hyper- or hypoglycemia (assessed by Clarke error grid analysis) were assessed.

Objective: To systematically map the existing evidence on self-perceived health among adults aged 60 and older in Latin America and the Caribbean, describe the use of the single-item measure of self-perceived health with this population, and identify gaps in the existing literature.
Methods: Following PRISMA Extension for Scoping Reviews guidelines, eight databases were searched for publications that were published between 2009 and 2019 and reported self-perceived health of adults over 60 years old in Latin America and the Caribbean. Data on study characteristics, sample characteristics, and the use and analysis of the self-perceived health measure were charted.
