NTNG1 mutations are a rare cause of Rett syndrome

A translocation that disrupted the netrin G1 gene (NTNG1) was recently reported in a patient with the early seizure variant of Rett syndrome (RTT).

The association between behaviour and genotype in Rett Syndrome using the Australian Rett Syndrome Database

This study compared the behavior profile of cases in the Australian Rett Syndrome Database (ARSD) with those in a British study using the Rett Syndrome...

The development, content and response process validation of a caregiver-reported severity measure for CDKL5 deficiency disorder

CDKL5 Deficiency Disorder (CDD) is a severe X-linked developmental and epileptic encephalopathy. Existing developmental outcome measures have floor effects and cannot capture incremental changes in symptoms. We modified the caregiver portion of a CDD clinical severity assessment (CCSA) and assessed content and response-process validity. 

Genotype and sleep independently predict mental health in Rett syndrome: An observational study

Rett syndrome is a genetically caused neurodevelopmental disorder associated with severe impairments and complex comorbidities. This study examined predictors of anxiety and depression in Rett syndrome, including genotype.

The Effect of Mineral Trioxide Aggregate Obturation Levels on the Outcome of Endodontic Retreatment: An Observational Study

No clinical studies have examined the effect of mineral trioxide aggregate (MTA) obturation levels on the outcome of endodontic retreatment. This retrospective study examined treatment outcomes in three cohorts that compared overfilling, flush filling, and underfilling after orthograde retreatment using MTA.

Can Wearable Inertial Measurement Units Be Used to Measure Sleep Biomechanics? Establishing Initial Feasibility and Validity

Wearable motion sensors, specifically, Inertial Measurement Units, are useful tools for the assessment of orientation and movement during sleep. The DOTs platform (Xsens, Enschede, The Netherlands) has shown promise for this purpose. This pilot study aimed to assess its feasibility and validity for recording sleep biomechanics.

Systematic Review and Meta-analysis: Early Irritability as a Transdiagnostic Neurodevelopmental Vulnerability to Later Mental Health Problems

Irritability is a transdiagnostic indicator of child and adolescent internalizing and externalizing problems that is measurable from early life. The objective of this systematic review was to determine the strength of the association between irritability measured from 0 to 5 years and later internalizing and externalizing problems, to identify mediators and moderators of these relationships, and to explore whether the strength of the association varied according to irritability operationalization.

Cerebral palsy: Epidemiology

Cerebral palsy (CP) is a lifelong physical disability, resulting from maldevelopment or damage to the developing brain. All children with CP have a disorder of movement and posture, but this is often accompanied by disorders of intellect, sensation, behaviour and epilepsy. Long-standing CP registers and surveillance systems estimate the prevalence of CP as approximately 2 per 1000 live births; however variations are seen over time and in different regions of the world.

Individual-Level Risk and Resilience Factors Associated with Mental Health in Siblings of Individuals with Neurodevelopmental Conditions: A Network Analysis

Siblings of individuals with neurodevelopmental conditions (NDCs) are exposed to unique family environments and experience a range of psychosocial risk and resilience factors.
