How do lifestyle and environmental factors influence the sperm epigenome? Effects on sperm fertilising ability, embryo development, and offspring health.

Recent studies support the influence of paternal lifestyle and diet before conception on the health of the offspring via epigenetic inheritance through sperm DNA methylation, histone modification, and small non-coding RNA (sncRNA) expression and regulation. Smoking may induce DNA hypermethylation in genes related to anti-oxidation and insulin resistance. Paternal diet and obesity are associated with greater risks of metabolic dysfunction in offspring via epigenetic alterations in the sperm.

Use of implementation logic models in the Quadruple Aim QUERI: conceptualization and evolution.

Background: Implementation strategies are essential to deliver evidence-based programs that align with local context, resources, priorities, and preferences. However, it is not always clear how specific strategies are selected (vs. others) and strategies are not always operationalized clearly, distinctly, and dynamically.

An exceptionally rare case of a diffuse midline glioma with concomitant H3.1 K27M and G34R mutations in the HIST1H3C (H3C3) gene.

Histone mutations (H3 K27M, H3 G34R/V) are molecular features defining subtypes of paediatric-type diffuse high-grade gliomas (HGG) (diffuse midline glioma (DMG), H3 K27-altered, diffuse hemispheric glioma (DHG), H3 G34-mutant). The WHO classification recognises in exceptional cases, these mutations co-occur. We report one such case of a 2-year-old female presenting with neurological symptoms; MRI imaging identified a brainstem lesion which was biopsied.

Intraprosthetic Dislocation Following Dual Mobility Total Hip Arthroplasty: A Retrieval Analysis Study.

Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Cerebrospinal fluid dynamics and subarachnoid space occlusion following traumatic spinal cord injury in the pig: an investigation using magnetic resonance imaging.

Background: Traumatic spinal cord injury (SCI) causes spinal cord swelling and occlusion of the subarachnoid space (SAS). SAS occlusion can change pulsatile cerebrospinal fluid (CSF) dynamics, which could have acute clinical management implications. This study aimed to characterise SAS occlusion and investigate CSF dynamics over 14 days post-SCI in the pig.
