Nitrous oxide (NO) commonly referred to as laughing gas, has significant medical uses. This study aims to describe the neurological disorders associated with NO. We conducted across-sectional study that enrolled patients with nitrous oxide toxicity admitted to Vietnam Poison Control Center, Bach Mai Hospital, Hanoi, Vietnam from June 2018 to July 2019. The questionnaire included demographic characteristics, characteristics of using NO, signs and clinical symptoms, neuroimaging findings, injury on electromyography (EMG) and the Total Neuropathy Score clinical version (TNSc) criteria. A total of 47 participants were included with mean age: 24.38 ± 6.20 years. The number of balloons used per week was 130.59 ± 117.43. The mean duration of NO exposure was 8.79 ± 7.1 months. Multivariate linear logistic regression revealed that the number of NO balloons used per week was significantly associated with TNSc point (Beta: 0.315; 95% CI: 0.001-0.022). We found that myeloneuropathy and peripheral neuropathy were the main neurological disorders related to NO abuse, which should improve the awareness of the appearance of neurological disorders associated with NO abuse.

Substantial evidence points to the early onset of peripheral inflammation in the development of Parkinson's disease (PD), supporting the "body-first" hypothesis. However, there remains a notable absence of PD-specific animal models induced by inflammatory cytokines. This study introduces a novel mouse model of PD driven by the proinflammatory cytokine CXCL1, identified in our previous research.

Iron is the most abundant transition metal in the brain and is essential for brain development and neuronal function; however, its abnormal accumulation is also implicated in various neurological disorders. The olfactory bulb (OB), an early target in neurodegenerative diseases, acts as a gateway for environmental toxins and contains diverse neuronal populations with distinct roles. This study explored the cell-specific vulnerability to iron in the OB using a mouse model of intranasal administration of ferric ammonium citrate (FAC).

In this article, we look at a selection of recent developments in various areas of endocrinology. We focus on advances in endocrine pharmacotherapy and endocrine surgery, addressing several areas: a) the thyroid safety of Glucagon-Like Peptide-1 (GLP1) analogues; b) the efficacy of adrenal surgery for mild autonomous cortisol secretion; c) crinecerfont in the management of congenital adrenal hyperplasia in adults and children; d) paltusotin as a novel oral therapy for acromegaly and e) TransCon PTH (palopegteriparatide) as a novel therapy for chronic hypoparathyroidism.

Post-stroke early activation of neutrophils contributes to intensive neuroinflammation and worsens disease outcomes. Other pre-existing patient conditions can modify the extent of their activation during disease, especially hypercholesterolemia. However, whether and how increased circulating cholesterol amounts can change neutrophil activation responses very early after stroke has not been studied.
