As global life expectancy rises, a growing proportion of the population is affected by dementia, particularly Alzheimer's disease (AD) and Frontotemporal dementia (FTD). Electroencephalography (EEG) based diagnosis presents a non-invasive, cost effective alternative for early detection, yet existing methods are challenged by data scarcity, inter-subject variability, and privacy concerns. This study proposes lightweight and privacy-preserving EEG classification framework combining deep learning and Federated Learning (FL).

Urdu and English are widely used for visual text communications worldwide in public spaces such as signboards and navigation boards. Text in such natural scenes contains useful information for modern-era applications such as language translation for foreign visitors, robot navigation, and autonomous vehicles, highlighting the importance of extracting these texts. Previous studies focused on Urdu alone or printed text pasted manually on images and lacked sufficiently large datasets for effective model training.

Background: Cardiac amyloidosis (CA) is the leading cause of mortality in systemic amyloidosis, highlighting the need for accurate risk assessment to guide patient management. While the diagnostic value of cardiac MR (CMR) parametric mapping is well established, its prognostic utility remains inconsistent across studies. To perform a systematic review and meta-analysis to evaluate the prognostic value of CMR parametric mapping in predicting all-cause mortality, heart failure hospitalisation and major adverse cardiovascular events in patients with CA.

Many neurodevelopmental defects are linked to genes involved in housekeeping functions, such as those encoding ribosome biogenesis factors. How reductions in ribosome biogenesis can result in tissue- and developmental-specific defects remains unclear. Here we describe variants in the ribosome biogenesis factor AIRIM/C1orf109 that are primarily associated with neurodevelopmental disorders.

Introduction: Neurodevelopmental disorders (NDDs) represent a diverse and heterogeneous group of conditions, including neurodevelopmental delay (NDD), autism spectrum disorder (ASD), and neurodevelopmental encephalopathy with epilepsy (NDEE). While these disorders often share phenotypic similarities, their underlying genetic causes can vary widely, making clinical diagnosis challenging.

Methods: In this study, we performed whole-genome sequencing (WGS) on a family having an autosomal recessive neurodevelopmental disorder.

Retinal diseases are among the leading causes of blindness worldwide, requiring early detection for effective treatment. Manual interpretation of ophthalmic imaging, such as optical coherence tomography (OCT), is traditionally time-consuming, prone to inconsistencies, and requires specialized expertise in ophthalmology. This study introduces OculusNet, an efficient and explainable deep learning (DL) approach for detecting retinal diseases using OCT images.

Background: Cardiovascular magnetic resonance mapping parameters-native T1 mapping, T2 mapping, and extracellular volume (ECV)-are key for diagnosing acute myocarditis under the modified 2018 Lake Louise Criteria (mLLC). This systematic review and meta-analysis evaluated their diagnostic performance and established optimal thresholds for acute myocarditis.

Methods: We reviewed articles published in the past decade utilizing parametric mapping for myocarditis diagnosis.

Glaucoma is a progressive eye condition caused by high intraocular fluid pressure, damaging the optic nerve, leading to gradual, irreversible vision loss, often without noticeable symptoms. Subtle signs like mild eye redness, slightly blurred vision, and eye pain may go unnoticed, earning it the nickname "silent thief of sight." Its prevalence is rising with an aging population, driven by increased life expectancy.

Introduction: Major Depressive Disorder (MDD) remains a critical mental health concern, necessitating accurate detection. Traditional approaches to diagnosing MDD often rely on manual Electroencephalography (EEG) analysis to identify potential disorders. However, the inherent complexity of EEG signals along with the human error in interpreting these readings requires the need for more reliable, automated methods of detection.

Background: Early infantile epileptic encephalopathy (EIEE) is a rare neurological condition characterized by frequent seizures in the early stages of life, resulting in severely impaired cognitive and motor development. Although the specific causes of EIEE remain unknown, one of the primary causes is gene pathogenicity (even in the absence of consanguinity). Hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) are essential for proper brain function.

. Two-dimensional (2D) woven fabrics are inefficient in exhibiting viable thermal comfort and protective function in high-tech applications that govern a need for three-dimensional (3D) weaves. Such 3D fabrics offer superior performance over 2D fabrics; however, no study has reported the simultaneous comparison of thermal and protective performance properties of 2D and 3D structures with equal thread densities.

Introduction: Atypical lipomatous tumours (ALTs), or low-grade well-differentiated liposarcomas (WDLs), can be identified using radiological complex septations and histological atypia. In our view, this is a confusing name that underestimates the risk of local recurrence of such tumours. Defining a management algorithm for differentiating a lipoma from an ALT is important for considering the best management of these patients.

Background: Type 2 diabetes mellitus (T2DM) is associated with myocardial fibrosis (MF), a major contributor to adverse cardiovascular outcomes. Cardiovascular magnetic resonance (CMR), specifically extracellular volume fraction (ECV) and native T1 mapping, offers a non-invasive approach to quantify MF. This study aims to evaluate the utility of ECV and native T1 mapping as biomarkers for cardiac fibrosis and to assess their relationship with diabetes severity, measured by hemoglobin A1C (HbA1C), in patients with T2DM.

Cardiac amyloidosis is an infiltrative cardiomyopathy caused by the deposition of insoluble amyloid fibrils in the myocardium, leading to abnormal cardiac function and heart failure. Diagnosis is often challenging due to its diverse symptoms and related comorbidities. Although endomyocardial biopsy is the gold standard for diagnosis, a complete diagnostic approach often includes non-invasive methods such as Cardiac Magnetic Resonance (CMR) and nuclear medicine techniques.
