Purpose: To understand the breadth of sensory dysregulation on participation in daily tasks for young people with tic disorders, as research identified that sensory dysregulation experiences are broader than the symptoms being assessed.

Methods: Eighteen semi-structured interviews were conducted with 16 families with children (5-16 years) with tic disorders. Interviews ranged from 45 to 120 min and were transcribed verbatim.

Resilience-based management is essential to protect ecosystems in the Anthropocene. Unlike large-scale climate threats to Great Barrier Reef (GBR) corals, outbreaks of coral-eating crown-of-thorns starfish (COTS; Acanthaster cf. solaris) can be directly managed through targeted culling.

Objectives: In this study, we propose a diagnostic model for automatic detection of otitis media based on combined input of otoscopy images and wideband tympanometry measurements.

Methods: We present a neural network-based model for the joint prediction of otitis media and diagnostic difficulty. We use the subclassifications acute otitis media and otitis media with effusion.

Article Synopsis
  • Young people with Duchenne muscular dystrophy (DMD) are at a higher risk for obesity, and this study aimed to explore a weight management program tailored for them and their families.
  • The Supporting Nutrition and Optimizing Wellbeing Program (SNOW-P) was a 6-week intervention conducted via telehealth, focusing on diet and behavior, and involved feedback from caregivers to shape its structure.
  • Results showed high participation and satisfaction, indicating feasibility and acceptability, but suggested improvements like the need for better online resources and a more accurate way to track weight and dietary habits.

Article Synopsis
  • The study investigates the challenges and perceptions caregivers face regarding nutrition and weight management for children with Duchenne muscular dystrophy (DMD), given that obesity can worsen health outcomes for these kids.
  • Researchers surveyed 53 caregivers across Australian clinics, revealing that nearly half believed their child was overweight, with over half citing issues like self-esteem and movement difficulties related to weight.
  • Caregivers expressed a desire for a structured, intensive six-week weight management program that would focus on appetite control and reducing screen time but identified barriers such as time constraints and a lack of nutrition knowledge.

Article Synopsis
  • The study focused on creating and evaluating a psychoeducational booklet to help parents engage in the wheelchair prescription process for their children with neuromuscular conditions.
  • Feedback from 27 parents and 9 clinicians showed that the booklet was well-received and effectively met the information and support needs of parents.
  • The results suggest the booklet is a valuable resource for enhancing parental involvement in clinical decisions, with future plans to assess its use in diverse cultural settings and to address the psychosocial needs associated with wheelchair prescriptions.

Background And Objectives: Charcot-Marie-Tooth disease type 1A (CMT1A), caused by a duplication of , is the most common hereditary peripheral neuropathy. For participants with CMT1A, few clinical trials have been performed; however, multiple therapies have reached an advanced stage of preclinical development. In preparation for imminent clinical trials in participants with CMT1A, we have produced a Clinical Outcome Assessment (COA), known as the CMT-Functional Outcome Measure (CMT-FOM), in accordance with the FDA Roadmap to Patient-Focused Outcome Measurement to capture the key clinical end point of function.

Background: Single-nucleotide polymorphisms linked with the rs1474868 T allele ( [mitofusin-2] T/T) in the human mitochondrial fusion protein gene are associated with reduced platelet RNA expression and platelet counts. This study investigates the impact of MFN2 on megakaryocyte and platelet biology.

Methods: Mice with megakaryocyte/platelet deletion of ( [ conditional knockout]) were generated using Pf4-Cre crossed with floxed mice.

Background: The small noncoding RNAs (sncRNAs) in megakaryocytes (MKs) and platelets are not well characterized. Neither is the impact of SARS-CoV-2 infection on the sncRNAs of platelets.

Objectives: To investigate the sorting of MK sncRNAs into platelets, and the differences in the platelet sncRNAomes of healthy donors (HDs) and COVID-19 patients.

Protease-activated receptor 4 (PAR4) (gene F2RL3) harbors a functional dimorphism, rs773902 A/G (encoding Thr120/Ala120, respectively) and is associated with greater platelet aggregation. The A allele frequency is more common in Black individuals, and Black individuals have a higher incidence of ischemic stroke than White individuals. However, it is not known whether the A allele is responsible for worse stroke outcomes.

Aims: To synthesize and critically appraise available interventions in the conservative management of hand impairment for children and adolescents with heritable disorders of connective tissue (HDCT).

Methods: A search of peer-reviewed literature and online platforms were included with data regarding hand impairment and function, conservative management and outcome measures extracted and appraised. Levels of evidence were applied to published literature.

The forward pressure has been proposed as an "optimal" reflectance-based quantity for delivering stimuli to the ear during evoked otoacoustic-emission measurements and audiometry. It is motivated by and avoids detrimental stimulus-level errors near standing-wave antiresonance frequencies when levels are adjusted in situ. While enjoying widespread popularity within research, the forward pressure possesses certain undesirable properties, some of which complicate its implementation into commercial otoacoustic-emission instruments conforming to existing international standards.

Background: Predicting morphological changes to anatomical structures from 3D shapes such as blood vessels or appearance of the face is a growing interest to clinicians. Machine learning (ML) has had great success driving predictions in 2D, however, methods suitable for 3D shapes are unclear and the use cases unknown.

Objective And Methods: This systematic review aims to identify the clinical implementation of 3D shape prediction and ML workflows.

The MAPK-interacting kinase (Mnk) family includes Mnk1 and Mnk2, which are phosphorylated and activated in response to extracellular stimuli. Mnk1 contributes to cellular responses by regulating messenger RNA (mRNA) translation, and mRNA translation influences platelet production and function. However, the role of Mnk1 in megakaryocytes and platelets has not previously been studied.

Recycling is increasingly visible in archaeological descriptions of technology. This has a range of benefits as we attempt to engage with the full complexity of the material past. However, this paper examines in more detail whether a singular focus on recycling is positive for archaeological science.
