G6PD deficiency triggers dopamine loss and the initiation of Parkinson's disease pathogenesis.

Loss of dopaminergic neurons in Parkinson's disease (PD) is preceded by loss of synaptic dopamine (DA) and accumulation of proteinaceous aggregates. Linking these deficits is critical to restoring DA signaling in PD. Using murine and human pluripotent stem cell (hPSC) models of PD coupled with human postmortem tissue, we show that accumulation of α-syn micro-aggregates impairs metabolic flux through the pentose phosphate pathway (PPP).

Risks of peri- and postoperative complications with glucagon-like peptide-1 receptor agonists.

Aim: To assess whether adults with diabetes on oral hypoglycaemic agents undergoing general endotracheal anaesthesia during nine common surgical procedures who are glucagon-like peptide-1 receptor agonist (GLP1-RA) users, compared with non-users, are at increased risk of six peri- and post-procedure complications.

Materials And Methods: A retrospective observational cohort analysis of over 130 million deidentified US adults with diabetes (defined as being on oral hypoglycaemic agents) from a nationally representative electronic health dataset between 1 January 2015 and 1 April 2023 was analysed. Cohorts were matched by high-dimensionality propensity scoring.

Evaluation of continuous aspiration of subglottic secretions in prevention of microaspiration during general anesthesia: a randomized controlled pilot study.

Aim: To assess the difference between endotracheal tubes (ETT) with continuous suction of subglottic secretions (CASS) and standard ETT in preventing secretions movement from the pharynx into the trachea, past the inflated cuff during general anesthesia.

Methods: This randomized, controlled trial enrolled 50 patients who underwent general anesthesia for elective abdominal surgery lasting longer than two hours. They received either ETT with CASS: Teleflex ISIS HVT (GISIS, n=17) or Mallinckrodt TaperGuard Evac (GEvac, n=17), or ETT without suction: Mallinckrodt Intermediate Hi-Lo (GStand, n=16).

Recent Developments in Health Insurance, Life Insurance, and Disability Insurance Law.

This year's article covers key recent developments in life, health, and disability insurance law, including Supreme Court decisions on the constitutionality of the Affordable Care Act's contraception coverage provisions and on the enforceability of legal actions limitations period provisions in Employee Retirement Income Security Act (ERISA) plan documents; an alarming (but potentially short-lived) expansion of restitution as a form of "equitable relief" under ERISA; the latest battles in the stranger originated life insurance (STOLI) wars; and perennial issues arising out of disability and accident insurance cases.

QuantitativeT2: interactive quantitative T2 MRI witnessed in mouse glioblastoma.

The aim of this study was to establish an advanced analytical platform for complex in vivo pathologies. We have developed a software program, QuantitativeT2, for voxel-based real-time quantitative T2 magnetic resonance imaging. We analyzed murine brain tumors to confirm feasibility of our method for neurological conditions.

Metabolic syndrome increases risk for pulmonary embolism after hip and knee arthroplasty.

Aim: To investigate whether patients with metabolic syndrome (MetS) undergoing total hip or knee replacement have an increased risk for pulmonary embolism (PE).

Methods: We studied patients undergoing total hip or total knee replacement from January 2001 to April 2006. The diagnosis of PE was based on a positive finding with a chest CT or a lung scan.

Preadmission hyperglycemia is an independent risk factor for in-hospital symptomatic pulmonary embolism after major orthopedic surgery.

We investigate whether preadmission hyperglycemia is a risk factor for developing in-hospital symptomatic pulmonary embolism after major orthopedic surgery. Medical records of patients undergoing total hip or total knee arthroplasty from January 2001 to April 2006 were reviewed. The incidence of PE was 1.

Mucosal insulin delivery systems based on complexation polymer hydrogels: effect of particle size on insulin enteral absorption.

Insulin-loaded polymer (ILP) microparticles composed of poly(methacrylic acid) and poly(ethylene glycol), which have pH-dependent complexation and mucoadhesive properties have been thought to be potential carriers for insulin via an oral route. Nevertheless, further optimization of the polymer delivery system is required to improve clinical application. Therefore, the effect of particle size of the ILP (L-ILP: 180-230 microm, S-ILP: 43-89 microm, SS-ILP: <43 microm) on insulin absorption was studied in the in situ loop system, hypothesizing smaller particle sizes of ILP could induce bigger hypoglycemic effects due to increase mucoadhesive capacity.
