Summary: Unsupervised machine learning provides tools for researchers to uncover latent patterns in large-scale data, based on calculated distances between observations. Methods to visualize high-dimensional data based on these distances can elucidate subtypes and interactions within multi-dimensional and high-throughput data. However, researchers can select from a vast number of distance metrics and visualizations, each with their own strengths and weaknesses. The Mercator R package facilitates selection of a biologically meaningful distance from 10 metrics, together appropriate for binary, categorical and continuous data, and visualization with 5 standard and high-dimensional graphics tools. Mercator provides a user-friendly pipeline for informaticians or biologists to perform unsupervised analyses, from exploratory pattern recognition to production of publication-quality graphics.
Availabilityand Implementation: Mercator is freely available at the Comprehensive R Archive Network (https://cran.r-project.org/web/packages/Mercator/index.html).

Phase I dose escalation trials in oncology generally aim to find the maximum tolerated dose. However, with the advent of molecular-targeted therapies and antibody drug conjugates, dose-limiting toxicities are less frequently observed, giving rise to the concept of optimal biological dose (OBD), which considers both efficacy and toxicity. The estimand framework presented in the addendum of the ICH E9(R1) guidelines strengthens the dialogue between different stakeholders by bringing in greater clarity in the clinical trial objectives and by providing alignment between the targeted estimand under consideration and the statistical analysis methods.

Objective: To assess the effect of the number of cellular and/or tissue-based product (CTP) applications on healing outcomes and wound area reduction (WAR) rates in patients with chronic wounds of multiple etiologies.
Methods: Data from a multicenter private wound care practice electronic health record database were analyzed for Medicare patients receiving CTPs from January 2018 through December 2023.

Background: A clear understanding of minimal clinically important difference (MCID) and substantial clinical benefit (SCB) is essential for effectively implementing patient-reported outcome measurements (PROMs) as a performance measure for total knee arthroplasty (TKA). Since not achieving MCID and SCB may reflect suboptimal surgical benefit, the primary aim of this study was to use machine learning to predict patients who may not achieve the threshold-based outcomes (i.e.

Theoretical approaches can help to plan, guide, and evaluate implementation projects that target real-world practice problems. This paper provides an overview of the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework and summarizes its use in nutrition and dietetics research and practice. A narrative summary of its use was compiled from the published literature based on citations from two key reference sources of the i-PARIHS framework.

Background: Brucellosis remains a significant public health and economic challenge in Egypt despite long-standing control efforts. This paper outlines the national strategy for brucellosis control, detailing its legal framework, diagnostic protocols, surveillance mechanisms, vaccination programs, and biosecurity measures.
Main Body: Egypt employs a dual approach of test-and-slaughter and selective vaccination, supported by serological and pathological diagnostics.
