In India, child sexual abuse is a widespread, serious, and long-growing problem. Children are generally abused by the people known to them and less likely by strangers. A majority of people remain numb about the issues because of fear, denial from the community and social stigma and also result in less reported cases among the victims.

Endometrial Cancer (EC) is one of the most common gynecological malignancies. Despite its prevalence, molecular pathways, such as the Sonic Hedgehog (SHH) pathway, have not been extensively studied in the context of EC. This study aims to explore the clinical implications of SHH expression in EC, potentially uncovering new insights into the disease's pathogenesis and offering valuable insights for therapeutic strategies in EC.

Article Synopsis
  • Multiple system atrophy (MSA) is a serious neurodegenerative disorder that significantly disrupts sleep, impacting the overall quality of life for patients and serving as a negative prognostic factor.
  • The study investigated sleep disturbances in 60 probable MSA patients in India, revealing a high prevalence of issues like REM behavior disorder, poor sleep quality, and insomnia, with poor sleep correlating to disease severity.
  • Findings suggest that the type of MSA (parkinsonian vs. cerebellar) does not notably affect sleep parameters, but the duration of REM behavior disorder is linked to worse sleep quality and disease progression.

Article Synopsis
  • Deep learning models using convolutional neural networks (CNNs) have been applied to classify Alzheimer's disease and assess dementia severity through 3D brain MRI scans, with a focus on improving interpretability using occlusion sensitivity analysis (OSA) and gradient-weighted class activation mapping (Grad-CAM).
  • The study investigates the effectiveness of these models, primarily trained on North American datasets, when applied to a different population in India (NIMHANS cohort), and assesses the advantages of utilizing a combined dataset for training.
  • Results demonstrate that feature localization aligns with established knowledge of Alzheimer's disease, indicating that OSA and Grad-CAM enhance interpretability by resolving diagnostic features at various scales.

We aimed to assess the incremental value of schizophrenia polygenic risk score (PgRS) and resting-state functional brain connectivity (rsFC) when added to clinical data in predicting the six-week response to oral risperidone (Risperdal) in schizophrenia. Fifty-seven, 54, and 43 individuals in a group of never-before-treated first-episode schizophrenia had good quality whole-genome sequencing (10x), rsFC, and both genomic and rsFC data, respectively, at baseline. Symptom severity ratings were obtained at baseline and six-weeks of oral risperidone (Risperdal) treatment.

Health Service and Population Research Department, Centre for Global Mental Health and Centre for Implementation Science, Institute of Psychiatry Psychology and Neuroscience, King's College London, London, UK.

Social contact refers to the facilitation of connection and interactions between people with and without mental health conditions. It can be achieved, for example, through people sharing their lived experience of mental health conditions, which is an effective strategy for stigma reduction. Meaningful involvement of people with lived experience (PWLE) in leading and co-leading anti-stigma interventions can/may promote autonomy and resilience.

Obstructive sleep apnea risk among adults with type 2 diabetes mellitus in an urban primary care setting of Mangalore, India.

J Family Med Prim Care

August 2024

Department of Epidemiology, National Institute of Mental Health and Neuro Sciences (NIMHANS), An Institute of National Importance, Bengaluru, Karnataka, India.

Background: Obstructive sleep apnea (OSA) is an under-evaluated and under-treated problem, particularly among individuals with type 2 diabetes mellitus (T2DM). Therefore, in this study, we aim to determine the risk of OSA among adults with T2DM residing in an urban area of Mangalore and to elucidate the determinants of OSA among the study participants.

Materials And Methods: A cross-sectional study was conducted for a period of 2 months among adult patients (≥ 18 years) with T2DM seeking health care at a primary care setting located in an urban area of Mangalore.

tDCS modulates the activity of the neuronal networks to induce the desired behavioural changes. Two factors determine its effectiveness- (1) whether the network being stimulated is relevant to the task, and (2) if there is a scope for improvement in behavioral performance. To explore this, both dorsal (sub-lexical) and ventral (lexical) reading networks were stimulated (20 min, 2 mA) in 25 healthy young volunteers.

J Prim Care Community Health

August 2024

Indian Council of Medical Research, New Delhi, India.

Introduction: Venous thromboembolism (VTE) is a multifactorial condition and one of the leading causes of mortality and disability. The present study explores the factors associated with hospitalization duration among different types of venous thromboembolism diagnoses, such as deep vein thrombosis (DVT), pulmonary embolism (PE), and other forms of thrombosis.

Methods: The data included participants with VTE admitted to 13 hospitals within pan-India from June 2022 to December 2023 to the i-RegVed registry, where socio-demographic data, clinical history, and various factors associated with hospital length of stay (LOS) were included for analyses.

Background: Tuberculomas are prevalent in developing countries and demonstrate variable signals on MRI resulting in the overlap of the conventional imaging phenotype with other entities including glioma and brain metastasis. An accurate MRI diagnosis is important for the early institution of anti-tubercular therapy, decreased patient morbidity, mortality, and prevents unnecessary neurosurgical excision. This study aims to assess the potential of radiomics features of regular contrast images including T1W, T2W, T2W FLAIR, T1W post contrast images, and ADC maps, to differentiate between tuberculomas, high-grade-gliomas and metastasis, the commonest intra parenchymal mass lesions encountered in the clinical practice.

Neurology

August 2024

From the Department of Neurology (D.M.), National Institute of Mental Health and Neuro Sciences, Bangalore, India; Prosserman Centre for Neuromuscular Disease (D.M., M.A., H.D.K., V.B., M.G.M., C.B.-T.), Toronto General Hospital, University Health Network; and Institute of Health Policy (C.B.-T.), Management and Evaluation, University of Toronto, Ontario, Canada.

Backgrounds And Objectives: Early use of immunosuppression has been suggested to prevent generalization of ocular myasthenia gravis (OMG), but high-quality evidence is limited in this regard. We examined whether treatment with prednisone and other immunosuppressants reduce the risk of generalization in OMG.

Methods: This is a retrospective study of consecutive adults with pure OMG who had a minimum 6 months of follow-up.
