The aim of this study was to assess the conceptual and operational descriptions of negative social networking site (SNS) use in adolescents. A search was conducted among four databases, following the guidelines set forth in the PRISMA-ScR. The search resulted in 1503 articles, of which 112 met the inclusion criteria. The results showed that the negative use of SNS has been conceptualised from two approaches: (1) the component model of addiction and (2) a cognitive-behavioural problematic use paradigm. Thirty-seven instruments assessing this problem were found, with the Bergen Facebook Addiction Scale and its adaptations being the most widely used ones. These instruments dimensions were vaguely defined and often overlapped with one another. In conclusion, no standardised theoretical framework exists to assess negative SNS use in adolescents. This lack of a theoretical definition makes it difficult to compare results among studies and determine the true extent of the problem.

Objective: The objective of study was to present evidence of the content validity of conceptual and operational definitions of the "Blood Transfusion Reaction (code 0700)" nursing outcome from the Nursing Outcomes Classification (NOC).
Method: A methodological study was implemented in four phases. The first phase consisted of a narrative literature review in which the main indicators related to blood transfusion were identified: 25 new indicators that were not present in NOC, in addition to 14 existing indicators, for a total of 39 to be studied.

Introduction: A coach's managerial and pedagogical tasks in the sports training process constitute the substantive core of their work, while decision-making serves as the fundamental method underpinning these tasks. Some decisions made by coaches result from deliberate, analytical thinking, which involves extensive information gathering, analysis, and discussion. Others, however, are made quickly and spontaneously, triggered by unforeseen situations during training or competition that demand immediate action.

Background: Educational research highlights active approaches to learning are more effective in knowledge retention and problem-solving. It has long been acknowledged that adapting to more active ways of learning form part of the challenge for new university students as the pedagogical distance between the didactical approach largely followed by secondary school systems the world over differs quite significantly from the often more student-led, critical approach taken by universities. University students encounter various learning challenges, particularly during the transition from secondary school to university.

To overcome the computational barriers of analyzing large-scale single-cell sequencing data, we introduce MetaQ, a metacell algorithm that scales to arbitrarily large datasets with linear runtime and constant memory usage. Inspired by cellular development, MetaQ conceptualizes each metacell as a collective ancestor of biologically similar cells. By quantizing cells into a discrete codebook, where each entry represents a metacell capable of reconstructing the original cells it quantizes, MetaQ identifies homogeneous cell subsets for efficient and accurate metacell inference.

Introduction: The management of patients with Polycythemia Vera (PV) traditionally includes low-dose aspirin, phlebotomy, and cytoreductive therapy for high-risk individuals. Recent evidence suggests that cytoreductive treatment may be warranted for patients with additional risk factors beyond the traditional criteria of a history of thrombosis and age over 60 years. Introducing new therapeutic agents, including ropeginterferon alfa-2b and ruxolitinib, enables a more personalized treatment approach tailored to individual patient characteristics.
