Neurodevelopmental disorders pose significant clinical challenges related to atypical brain development, often manifesting as learning disabilities, developmental delays, intellectual deficits, behavioral issues, epilepsy, and sleep disturbances. Among genetic neuropsychiatric conditions, synaptopathies are notable for their impact on synaptic function, resulting in varied neuropsychiatric phenotypes. Among these, SYNGAP1-associated syndrome is characterized by intellectual disability, global developmental delay, autism, and epilepsy, primarily due to loss-of-function mutations.

 The absence of standardized reporting for sleep medicine exams across different laboratories can lead to misinterpretation, diagnostic inconsistencies, and suboptimal treatment strategies. This document seeks to establish guidelines for the development of sleep study reports, covering recordings from studies of types 1 to 4, and represents the official position of Associação Brasileira do Sono (ABS; Brazilian Sleep Association) on the standardization of polysomnography (PSG) and cardiorespiratory polygraphies.  The recommendations for the items to be reported in PSG records were developed by means of a Delphi study, comprised of two voting rounds.

Article Synopsis
  • Myasthenia gravis (MG) is an autoimmune disease that causes muscle weakness due to the destruction of acetylcholine receptors at the neuromuscular junction.
  • Treatment for patients with both MG and obstructive sleep apnea (OSA) often includes positive pressure airway therapy, but adherence to this treatment can be challenging, leading to worse health outcomes.
  • This report focuses on a case study of a 50-year-old man with MG and OSA, examining how he responded to various treatment methods.

Article Synopsis
  • * The system simplifies signal processing by using the same chirped waveform for both transmission and local oscillation, allowing the receiver's bandwidth to be lower than the signal's chirping bandwidth.
  • * This setup enables the simultaneous detection of a target's range and velocity, and experimental results show the capability for multi-target detection as well.

Over the past decade, several urban visual analytics systems and tools have been proposed to tackle a host of challenges faced by cities, in areas as diverse as transportation, weather, and real estate. Many of these tools have been designed through collaborations with urban experts, aiming to distill intricate urban analysis workflows into interactive visualizations and interfaces. However, the design, implementation, and practical use of these tools still rely on siloed approaches, resulting in bespoke systems that are difficult to reproduce and extend.

This research project investigated the relationship between sociodemographic characteristics of girls and women who were the victims of rape of in Minas Gerais between 2013 and 2021, and the likelihood of receiving emergency treatment as stipulated in Law No. 12,845/2013, known as the "Minute-After" (Minuto Seguinte) Law. Data from the Notifiable Diseases Information System (SINAN) for rape cases were used to estimate binary choice models.

Article Synopsis
  • - The study investigates sleep disturbances and epilepsy in patients with SYNGAP1-associated syndrome, a rare neurodevelopmental disorder that leads to intellectual disability and other challenges.
  • - An online survey involving 11 caregivers revealed that 82% of patients experienced epilepsy, with a significant number showing drug-resistant seizures and poor sleep habits, as assessed by standardized questionnaires.
  • - Findings indicate that both patients and caregivers struggle with sleep quality, underscoring the need for further research and interventions aimed at improving sleep and overall quality of life in individuals affected by this syndrome.

Heart failure (HF) is the common final pathway of several conditions and is characterized by hyperactivation of numerous neurohumoral pathways. Cardiorenal interaction plays an essential role in the progression of the disease, and the use of diuretics is a cornerstone in the treatment of hypervolemic patients, especially in acute decompensated HF (ADHF). The management of congestion is complex and, to avoid misinterpretations and errors, one must understand the interface between the heart and the kidneys in ADHF.

Introduction: The objective of this study was to verify changes in behavioral abilities and cognitive functions after rapid maxillary expansion (RME) in children with refractory sleep-disordered breathing (SDB) in the long term after adenotonsillectomy.

Methods: A prospective clinical trial study using RME therapy was conducted. Participant inclusion criteria were children who had adenotonsillectomy with maxillary transverse deficiency and persistent SDB (obstructive apnea-hypopnea index ≥1).

While cities around the world are looking for smart ways to use new advances in data collection, management, and analysis to address their problems, the complex nature of urban issues and the overwhelming amount of available data have posed significant challenges in translating these efforts into actionable insights. In the past few years, urban visual analytics tools have significantly helped tackle these challenges. When analyzing a feature of interest, an urban expert must transform, integrate, and visualize different thematic (e.

Monoclonal antibodies (mAbs) are valuable biological molecules, serving for many applications. Therefore, it is advantageous to know the interaction pattern between antibodies and their antigens. Regions on the antigen which are recognized by the antibodies are called epitopes, and the respective molecular counterpart of the epitope on the mAbs is called paratope.

Phage display is an efficient and robust method for protein-protein interaction studies. Although it is mostly used for antibody generation, it can be also utilized for the discovery of immunogenic proteins that could be used as biomarkers. Through this technique, a genome or metagenome is fragmented and cloned into a phagemid vector.

Listeria adhesion protein (LAP) is a secreted acetaldehyde alcohol dehydrogenase (AdhE) that anchors to an unknown molecule on the Listeria monocytogenes (Lm) surface, which is critical for its intestinal epithelium crossing. In the present work, immunoprecipitation and mass spectrometry identify internalin B (InlB) as the primary ligand of LAP (K ∼ 42 nM). InlB-deleted and naturally InlB-deficient Lm strains show reduced LAP-InlB interaction and LAP-mediated pathology in the murine intestine and brain invasion.

Objectives: Primary objectives were to analyze the prevalence of obstructive sleep apnea in (1) boys and girls, and (2) severe asthma versus moderate and mild cases. The authors hypothesized that girls and severe asthma would have a higher prevalence of obstructive sleep apnea.

Methods: Cross-sectional evaluation of asthmatic children attending a tertiary Pediatric Pulmonology clinic.

Lectins are proteins that reversibly bind to carbohydrates and are commonly found across many species. The Banana Lectin (BanLec) is a member of the Jacalin-related Lectins, heavily studied for its immunomodulatory, antiproliferative, and antiviral activity. In this study, a novel sequence was generated in silico considering the native BanLec amino acid sequence and 9 other lectins belonging to JRL.

Objective: To assess the short-term outcome of rapid maxillary expansion (RME) on periodic limb movement disorder (PLMD) in children with residual snoring after late adenotonsillectomy (AT).

Methods: This prospective clinical trial included 24 patients treated with rapid maxillary expansion (RME). Participants' inclusion criteria were children with maxillary constriction aged 5-12 years who had AT for more than two years and those whose parents/guardians reported that they still snored ≥4 nights per week.

Article Synopsis
  • Sleep-related issues are common in early-onset epileptic encephalopathies and developmental delays, especially in autism spectrum disorders, but the genetic connections are not well understood.
  • A gene enrichment study identified common risk genes and pathways between sleep disturbances and rare genetic syndromes, showing notable overlaps in genes related to synaptic functions.
  • The findings suggest that specific molecular mechanisms linked to circadian rhythm disruptions might underlie both sleep problems and neurodevelopmental disorders, paving the way for future research into these shared biological factors.
