Sensory processing, along with the integration of external inputs into stable representations of the environment, is integral to social cognitive functioning; challenges in these processes have been reported in Autism Spectrum Disorder (ASD) since the earliest descriptions of autism. Recently, neuroplasticity-based targeted cognitive training (TCT) has shown promise as an approach to improve functional impairments in clinical patients. However, few computerized and adaptive brain-based programs have been trialed in ASD.

Background: More than 50 countries, mainly in Sub-Saharan Africa and South Asia, are not on course to meet the neonatal and under-five mortality target set by the Sustainable Development Goals (SDGs) for the year 2030. One important, yet neglected, aspect of child mortality rates is deaths occurring during the post-discharge period. For children living in resource-poor countries, the rate of post-discharge mortality within the first several months after discharge is often as high as the rates observed during the initial admission period.

Dolutegravir's therapeutic effectiveness in the management of neuroAIDS is mainly limited by its failure to cross the blood-brain barrier. However, lipid-based nanovesicles such as nanoemulsions have demonstrated their potential for the brain targeting of various drugs by intranasal delivery. Thus, the purpose of this study was to develop a Dolutegravir-loaded nanoemulsion-based in situ gel and evaluate its prospective for brain targeting by intranasal delivery.

Introduction: Large vessel occlusion (LVO) stroke is a common presentation of acute ischemic stroke and is often unknown or cryptogenic in etiology. There is a strong association between atrial fibrillation (AF) and cryptogenic LVO stroke, making it a unique stroke subgroup. Therefore, we propose that any LVO stroke meeting the criteria for an embolic stroke of an undetermined source (ESUS) be classified as large ESUS (LESUS).

The Sudan virus disease outbreak in Uganda in 2022 showed our vulnerability to viral haemorrhagic fevers (VHFs). Although there are regular outbreaks of VHFs with high morbidity and mortality, which disproportionally affect low-income settings, our understanding of how to treat them remains inadequate. In this systematic review, we aim to explore the availability, scope, standardisation, and quality of clinical management guidelines for VHFs.

Article Synopsis
  • Triple negative breast cancer (TNBC) is responsible for over 30% of breast cancer deaths, yet it represents only 10-15% of all cases, highlighting a significant challenge in treatment.
  • Research using CRISPR/Cas9 screening identified that TNBC cells are particularly sensitive to the depletion of UBA1, a ubiquitin-like modifier activating enzyme.
  • The UBA1 inhibitor TAK-243 induces severe ER stress and cell death in TNBC cells, particularly those with high c-MYC levels, showing promise for shrinking tumors and reducing metastasis in both lab models and patient-derived xenografts.

Aims: The aim of this study was to compare procedural efficacy and safety, including 1-year freedom from AF recurrence, between the novel cryoballoon system PolarX (Boston Scientific) and the Arctic Front Advance Pro (AFA-Pro) (Medtronic), in patients with paroxysmal AF undergoing PVI.

Methods And Results: This multicentre prospective observational study included 267 consecutive patients undergoing a first cryoablation procedure for paroxysmal AF (137 PolarX, 130 AFA-Pro). Kaplan-Meier curves with the log-rank test was used to compare the 1-year freedom from AF recurrence between both groups.

The dynamic interplay of signaling networks in most major cellular processes is characterized by the orchestration of reversible protein phosphorylation. Consequently, analytic methods such as quantitative phospho-peptidomics have been pushed forward from a highly specialized edge-technique to a powerful and versatile platform for comprehensively analyzing the phosphorylation profile of living organisms. Despite enormous progress in instrumentation and bioinformatics, a high number of missing values caused by the experimental procedure remains a major problem, due to either a random phospho-peptide enrichment selectivity or borderline signal intensities, which both cause the exclusion for fragmentation using the commonly applied data dependent acquisition (DDA) mode.

Autism spectrum disorder is the most used umbrella term for a myriad of neuro-degenerative/developmental conditions typified by inappropriate social behavior, lack of communication/comprehension skills, and restricted mental and emotional maturity. The intriguing factor of this disorder is attributed to the fact that it can be detected only by close monitoring of developmental milestones after childbirth. Moreover, the exact causes for the occurrence of this neurodevelopmental condition are still unknown.

Transesophageal echocardiography (TEE) has become an indispensable part of cardiac surgery, but its potential for assessing coronary anatomy and blood flow remains underutilised. This case report presents a case of acute iatrogenic left main coronary artery obstruction following re-operative aortic valve replacement that was promptly diagnosed by intraoperative TEE and managed successfully by Bentall operation. We also emphasise the technique of TEE for coronary evaluation, its caveats and its clinical application during cardiac surgery.

Recent evidence suggests that genetic and epigenetic mechanisms might be associated with acquired resistance to cancer therapies. The aim of this study was to assess the association of genome-wide genetic and epigenetic alterations with the response to anti-HER2 agents in HER2-positive breast cancer patients. PubMed was screened for articles published until March 2021 on observational studies investigating the association of genome-wide genetic and epigenetic alterations, measured in breast cancer tissues or blood, with the response to targeted treatment in HER2-positive breast cancer patients.

Vulnerable patient populations have seen decreased rates of vaccination against SARS-CoV2-19 (COVID-19) due to hesitancies and distrust, magnified by a paucity of data for certain populations. The rate of COVID-19 vaccination in children with sickle cell disease (SCD) remains low despite the risk for severe complications, resulting in continued infections and hospitalizations from COVID-19. We sought to describe vaccine reactions, including vaso-occlusive crises, emergency department visits, and hospitalizations, in children with SCD.

Floppy or irregular irides may be seen during endothelial keratoplasty in complex cases or in eyes with damaged irides and may cause uneven air fill, retro-pupillary air escape, anterior bowing of iris, forward movement of lens-iris diaphragm, shallowing of anterior chamber (AC), bellowing and floppiness of iris, uneven AC depth, difficulty in inserting and opening graft, iris trauma, intraoperative bleeding, and iridodialysis. We present a technique of iridodiathermy for tautening and flattening such irides. With continuous irrigation using AC maintainer, the bipolar endodiathermy probe tip is applied in localized spots to midperipheral iris in the affected area with power and duration adjusted to induce mild localized shrinkage and tightening of iris stroma.
