A toddler presented to audiovestibular medicine with mild bilateral, sensorineural hearing loss identified via the Newborn Hearing Screening Programme. This report focuses on the early clinical assessment and aetiological investigation which prompted testing for metabolic disease and highlights the parents' perspective. Early investigation led to a relatively early diagnosis of mucopolysaccharidosis (MPS) type IIIA: Sanfilippo disease which enabled the family to access a novel treatment option which otherwise would not have been possible.

Background: Hepatitis B virus (HBV) and Hepatitis C virus (HCV) show similarity in the transmission, distribution, hepatotropism, and leading to chronic asymptomatic infection. Coinfection of HBV and HCV can lead to more severe liver disease and an increased risk for progression to hepatocellular carcinoma (HCC). Most of the people with chronic infection are unaware of their HBV and HCV infections, hence facilitating these to go undiagnosed until these viruses have caused serious liver damage and they act as a potential source of infection for the community at large.

Purpose: Meningiomas are central nervous system tumors whose incidence increases with age. Benign meningioma pathogenesis involves germline or somatic mutation of target genes, such as NF2, leading to clonal expansion. We used an established cancer epidemiology model to investigate the number of rate-limiting steps sufficient for benign meningioma development.

Article Synopsis
  • Recent studies highlight significant gaps in equity, diversity, and inclusion (EDI) within the AI lifecycle, from data collection to implementation, and lack established guidelines for integration.
  • The objective of the study was to develop a comprehensive guiding framework for integrating EDI principles into the AI development process, aimed at addressing these identified gaps.
  • The EDAI framework was created through a systematic scoping review and feedback from multidisciplinary workshops, providing guidelines to facilitate EDI integration across all stages of the AI lifecycle while identifying challenges and supports for this integration.

  • * A total of 4872 features were extracted from various MRI sequences, and LASSO regression helped reduce these features to 176 for model building. Five different machine learning algorithms were tested, with CatBoost performing the best based on various performance metrics.
  • * The results indicate that this radiomics-based approach could allow for non-invasive, pre-operative grading of meningiomas, but more testing on larger datasets is needed to confirm these findings.

Background: There is scarce knowledge on the use of structured positive psychology interventions for reducing work-stress and improving wellbeing of rural community health workers in India, particularly the Accredited Social Health Activists (ASHAs) who are village-level (resident women, incentivised) lay health workers. This trial will test the effectiveness of a 'character-strengths' based coaching intervention compared to routine supervision on wellbeing ('authentic happiness') of ASHAs.

Methods: This protocol is for a single-blind, parallel group randomized controlled trial comparing the effectiveness of a five-day residential workshop focusing on the use of character-strengths and subsequent 8- to 10-week remote telephonic coaching (weekly) to individually support ASHAs to improve their wellbeing, against routine health system support.

Article Synopsis
  • Direct pulp capping (DPC) is a dental procedure where exposed pulp is covered with materials to help it heal and form a protective dentin bridge.
  • Calcium hydroxide is the traditional choice for this, but mineral trioxide aggregate (MTA) and rosuvastatin are also studied for their effectiveness in promoting pulp healing.
  • The study aims to compare the effects of rosuvastatin and MTA on pulp-dentin complex reactions in permanent human molars after DPC, focusing on reparative dentin formation over a 90-day period.

  • Endovascular embolization is used as a supportive treatment for meningioma surgery, but evaluating its effectiveness is complicated because MRI scans are done before embolization and after the tumor is removed.
  • Researchers conducted a study using preoperative MRI after embolization to better measure how effective the procedure was, grading the extent of tumor devascularization and analyzing differences based on tumor location and blood supply.
  • The study found that the degree of devascularization correlated well with the volumetric extent of embolization, providing a clearer and more quantifiable way to assess the effectiveness of embolization before surgery.

  • Chiari malformation type I (CM-1) involves the herniation of brain tissue through the foramen magnum, presenting various clinical symptoms, which this study investigates through brain imaging and analysis of morphometric features.
  • The research reviewed data from 72 CM-1 patients and 26 healthy volunteers, finding distinct differences in brain structure volumes, including decreased volumes in critical areas and increased tonsillar size in CM-1 patients.
  • The study concludes that the amount of neural tissue at the foramen magnum strongly correlates with the need for surgical intervention and the presence of syrinxes, indicating a compressive phenomenon in the posterior fossa as a key factor in CM-1 symptoms.
