Galanin (GAL) and gamma amino butyric acid (GABA) are orexigenic neuropeptides that could contribute to the pathogenesis of anorexia nervosa (AN). To avoid the confounding effects of the ill state, we studied women who were recovered (> 1 year, normal weight, and regular menstrual cycles, no binging or purging) from AN (REC AN) and matched healthy control women (NC). CSF GAL was reduced in REC AN (64.4 +/- 8.6 pg/ml) compared to NC (72.0 +/- 11.6 pg/ml; p <.05), GABA was similar between groups. In the brain, GAL stimulates appetite and fat consumption. These data raise the question of whether alterations in brain GAL activity plays a role in clinical symptoms in AN, such as food restriction and fat avoidance.

Background: This study explores the impact of sleep disturbances on gray matter structural covariance networks (SCNs) across the Alzheimer's disease (AD) continuum.
Methods: Amyloid-negative participants served as controls, whereas amyloid positive (A+) individuals were categorized into six groups based on cognitive status and sleep quality. SCNs for the default mode network (DMN), salience network (SN), and executive control network (ECN) were derived from T1-weighted magnetic resonance images.

Early diagnosis and appropriate treatment are essential for reducing morbidity and mortality in tuberculous meningitis (TBM). This study aimed to evaluate the diagnostic performance of the Xpert MTB/RIF assay for the diagnosis of TBM in patients with subacute lymphocytic meningitis. This cross-sectional study included 65 cerebrospinal fluid (CSF) specimens from patients at Maharaj Nakorn Chiang Mai University Hospital, Thailand, between January 2015 and March 2016.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.
Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.

A 78-years-old man was treated for asthma and pansinusitis for >5 years, and mepolizumab was initiated two years previously. Two months after the cessation of mepolizumab treatment, the asthma symptoms worsened and acute progressive muscle weakness and sensory disturbance developed. On day 8 after the onset of weakness and hypoesthesia, the patient presented with complete flaccid tetraplegia and diffuse hypoesthesia of all extremities, without paresthesia or pain, and was admitted to our hospital.

This study aimed to evaluate the usefulness of amplicon-based real-time metagenomic sequencing applied to cerebrospinal fluid (CSF) for identifying the causative agents of bacterial meningitis. We conducted a 16S rRNA amplicon sequencing using a nanopore-based platform, alongside routine polymerase chain reaction (PCR) testing or bacterial culture, to compare its clinical performance in pathogen detection on CSF samples. Among 17 patients, nanopore-based sequencing, multiplex PCR, and bacterial culture detected potential bacterial pathogens in 47.
