A need to enhance healthcare sector amidst pandemic arises. Many technological developments in Artificial Intelligence (AI) are being constantly leveraged in different fields of healthcare. One such advancement, Federated Learning(FL) has acquired recognition primarily due to its decentralized, collaborative nature of building AI models. The most significant feature in FL is that, raw data remain with the data sources throughout the training process and thus preventing its exposure. Hence, FL is more suitable and inevitable in healthcare domain as it deals with private sensitive data which needs to be protected. However, privacy threats still exist in FL, necessitating a requirement for further improvement in privacy protection This paper discusses about the concepts and applications of FL in healthcare and presents a novel approach for enhancing privacy preservation in Federated Learning.

Department of Physical Education and Sport, University of Valencia, Valencia, Spain.
Tennis equipment modifications, such as smaller rackets and low-compression balls, are increasingly being used because they can better align with beginners' physical capabilities, enhancing learning and engagement. This scoping review aimed to map current research on equipment modifications for beginner tennis players, identifying how these modifications impact skill acquisition, game performance, biomechanical variables, psychological aspects, and coaches' perspectives. Searches across the Web of Science, Scopus, PubMed, and SPORTDiscus, along with expert input following the PRISMA procedures, yielded 35 studies.

Community-based participatory research provides communities with an avenue to actively collaborate with environmental researchers. The research aims to gain insight into critical problems of concern to community members while maintaining community autonomy over the research and its outcomes. This article describes the development and implementation of an environmental health communication tool designed to meet the needs of residents of Colfax, Louisiana, a rural community with limited technological access, which is engaging in advocacy with federal and state regulatory agencies to prohibit open burning and open detonation of military and Superfund wastes at a nearby thermal treatment site.

Background: Dengue fever is a mosquito-borne viral disease that poses significant health risks and socioeconomic challenges in Brazil, necessitating accurate forecasting across its 27 federal states. With the country's diverse climate and geographical spread, effective dengue prediction requires models that can account for both climate variations and spatial dynamics. This study addresses these needs by using Long Short-Term Memory (LSTM) neural networks enhanced with SHapley Additive exPlanations (SHAP) integrating optimal lagged climate variables and spatial influence from neighboring states.

Predicting and quantifying phenotypic consequences of genetic variants in rare disorders is a major challenge, particularly pertinent for 'actionable' genes such as thyroid hormone transporter MCT8 (encoded by the X-linked SLC16A2 gene), where loss-of-function (LoF) variants cause a rare neurodevelopmental and (treatable) metabolic disorder in males. The combination of deep phenotyping data with functional and computational tests and with outcomes in population cohorts, enabled us to: (i) identify the genetic aetiology of divergent clinical phenotypes of MCT8 deficiency with genotype-phenotype relationships present across survival and 24 out of 32 disease features; (ii) demonstrate a mild phenocopy in ~400,000 individuals with common genetic variants in MCT8; (iii) assess therapeutic effectiveness, which did not differ among LoF-categories; (iv) advance structural insights in normal and mutated MCT8 by delineating seven critical functional domains; (v) create a pathogenicity-severity MCT8 variant classifier that accurately predicted pathogenicity (AUC:0.91) and severity (AUC:0.

Federated learning (FL) has shown great potential in medical image computing since it provides a decentralized learning paradigm that allows multiple clients to train a model collaboratively without privacy leakage. However, current studies have shown that data heterogeneity incurs local learning bias in classifiers and feature extractors of client models during local training, leading to the performance degradation of a federation system. To address these issues, we propose a novel framework called Federated Bias eliMinating (FedBM) to get rid of local learning bias in heterogeneous federated learning (FL), which mainly consists of two modules, i.
