  • Deep Learning (DL) models are being effectively used to analyze MRI scans for Alzheimer's Disease (AD), leveraging Cloud Computing to manage computational demands.
  • The article provides a systematic tutorial on medical imaging datasets, presenting a case study that compares three DL models: Convolutional Neural Networks (CNN), Visual Geometry Group 16 (VGG-16), and an ensemble approach for AD MRI classification.
  • Results indicate that CNN achieved the highest accuracy at 99.285%, while VGG-16 and the ensemble model scored lower, emphasizing the effectiveness of the proposed cloud-based framework for secure and efficient medical image processing.

This research investigates the dynamics of nonlinear coupled hybrid systems using a modified Mittag-Leffler fractional derivative. The primary objective is to establish criteria for the existence and uniqueness of solutions through the implementation of Dhage's hybrid fixed-point theorem. The study further analyzes the stability of the proposed model.

Introduction: Chronic ocular hypotony (low intraocular pressure (IOP)) is a potentially sight-threatening condition. Although there is some controversy as to what constitutes non-physiological IOP, generally it is accepted as an IOP of 6.5 mm Hg or less, measured on three separate occasions and lasting for at least 3 months.

Article Synopsis
  • Heart failure is prevalent among hemodialysis patients, and high flow arteriovenous fistulas (AVFs) may be a risk factor; this study aims to create a predictive model to identify patients at risk of developing high flow AVFs.
  • Using data from 366 patients, the study compared various machine learning models to predict high flow AVF development, finding that the bootstrap forest model was the most effective.
  • Results showed that while 31.4% of patients had high flow AVFs, and 24.9% developed heart failure after AVF creation, no direct correlation was found between AVF flow and the onset of heart failure or death post-creation.

The COVID-19 pandemic has emerged as a global health crisis, impacting millions worldwide. Although chest computed tomography (CT) scan images are pivotal in diagnosing COVID-19, their manual interpretation by radiologists is time-consuming and potentially subjective. Automated computer-aided diagnostic (CAD) frameworks offer efficient and objective solutions.

MCARH109 is a first-in-class G protein-coupled receptor, class C, group 5, member D (GPRC5D)-targeted chimeric antigen receptor (CAR) T-cell therapy for patients with relapsed/refractory multiple myeloma. This phase I clinical trial included 17 patients and determined that MCARH109 is safe at a maximum tolerated dose of 150 × 10 CAR T cells. In this updated analysis, no new serious adverse events were reported at a median follow-up of 37 months.

Background: Proteomic phenotyping can provide insights into rejection pathophysiology, novel biomarkers, and therapeutic targets.

Methods: Within the prospective, multicenter Genomic Research Alliance for Transplantation study, 181 proteins were evaluated from blood drawn at the time of endomyocardial biopsy; protein fold change, logistic regression, and pathway analyses were conducted, with protein discovery adjusted for a 5% false discovery rate.

Results: Among 104 adult heart transplant patients (31% female sex, 53% Black race, median age 52 y), 74 had no rejection, 18 developed acute cellular rejection (ACR), and 12 developed antibody-mediated rejection (AMR).

Background: Hypertension prediction using anthropometry and bioimpedance offers practical advantages for screening. We aimed to analyze various anthropometric and bioelectrical impedance (BIA) estimates as predictive markers of prehypertension and hypertension.

Methods: This cross-sectional analysis included 432 adult participants recruited from the medicine outpatient department of a tertiary hospital.

Background: Disability impacts many individuals, thus restricting access to necessary healthcare. Barriers that affect health equity among people with disabilities include physical inaccessibility, financial constraints, and stigma in society. This study aims to report on the level of disability and factors determining healthcare access among adult differently abled persons in Chennai, Tamil Nadu, focusing on the WHO Disability Assessment Schedule (WHODAS 2.

Introduction: Social health is increasingly a focus of healthcare systems. Representative and intersectional analyses of individuals' social risks such as food, housing, transportation, and financial insecurity and their interest in receiving assistance from the healthcare system (social needs) can provide healthcare organizations with more nuanced estimates that can lead to more effective interventions.

Methods: The authors conducted cross-sectional survey of a representative sample of 43,936 Kaiser Permanente members in December 2019-September 2020.

Globally, care experiences of the growing population of contraceptive users are not well-understood. We leverage a large client dataset (n = 71,602) from three countries (Burkina Faso, Pakistan, and Tanzania) to characterize contraceptive services sought (visit objective and method preference), assess whether these visit objectives were met and for whom, and explore if visit objective fulfillment was associated with care quality. Most people in all three countries said they were seeking to continue their current method or adopt a method for the first time.

Microplastics (MPs) are tiny plastic pieces having a diameter of less than 5 mm. They can arise from larger plastic debris that degrades over time, synthetic fibres from clothing, microbeads in personal care items and even larger plastic debris. Sea cucumbers are marine creatures vital to the ocean's ecosystem as they assist in maintaining a clean seabed and recycle nutrients.

Environmentally hazardous radioactive isotopes of iodine may be released from a nuclear power plant as a by-product of uranium fission. The efficient and safe capture of volatile radioiodine is of great significance in the history of nuclear power plants. Due to its high volatility and carcinogenic characteristics, elimination of iodine gas (I) from air is the need of the hour from an environmental and health point of view.

Article Synopsis
  • Neurogenic stress cardiomyopathy (NSC) was found in 21% of 688 adult ischemic stroke patients, with characteristics including a mean age of 68, low left ventricular ejection fraction in 64%, and elevated Troponin-I in 40% of cases.
  • The study analyzed various stroke mechanisms, revealing that 43% were cryptogenic and showed that 12% of patients with NSC experienced leukocytosis, but this was not significantly different from the 8% in patients without NSC.
  • The findings suggest a need to define neurogenic stress cardiomyopathy based on specific cardiac biomarkers and highlight the importance of further research to pinpoint its risk factors.*

Leveraging the features of the GstLAL pipeline, we present the results of a matched filtering search for asymmetric binary black hole systems with heavily misaligned spins in LIGO and Virgo data taken during the third observing run. Our target systems show strong imprints of precession whereas current searches have nonoptimal sensitivity in detecting them. After measuring the sensitivity improvement brought by our search over standard spin-aligned searches, we report the detection of 30 gravitational wave events already discovered in the latest version of the Gravitational Wave Transient Catalog.

Loss of proteostasis is a hallmark of aging and Alzheimer disease (AD). We identify β-hydroxybutyrate (βHB), a ketone body, as a regulator of protein solubility. βHB primarily provides ATP substrate during periods of reduced glucose availability, and regulates other cellular processes through protein interactions.
