Objectives: Energy drink (ED) consumption is frequently observed among higher education students and is often associated with increased concentration and academic performance. However, the purported benefits are not fully supported by scientific evidence. This protocol details methods for a systematic review and meta-analysis to evaluate the effects of ED on university students’ mental health and academic performance. Methods: The PECO framework will guide the search strategy, and the protocol will follow the PRISMA-P 2015, PRESS 2015, and PRISMA-S guidelines. The searches will be conducted in the following databases: Web of Science, Scopus, Ovid, PubMed, Embase, FSTA, CINAHL, and SPORTDiscus. The GRADE recommendations and the Downs and Black scale will assess study quality and bias. All statistical analyses will be conducted using Comprehensive Meta-analysis software. We will use Cochran’s Q with p < 0.05 to indicate significant heterogeneity and I² to quantify heterogeneity between studies. The Trim and Fill technique and Egger’s regression test will be applied to evaluate the funnel plot that will be generated. Results: Carrying out the systematic review proposed by this protocol will provide evidence on the short-, medium-, and long-term effects of ED use on academic performance and mental health among higher education students. Conclusion: A deeper understanding of ED consumption among higher education students can inform the development of evidence-based educational and public health policies to promote student well-being and mitigate associated health risks.

Domestic violence (DV) against women in intimate relationships is a global public health issue with significant legal and institutional challenges. While legal reforms seek to enhance victim protection and perpetrator accountability, their implementation faces barriers within the criminal justice system, particularly in police and judicial institutions. A multi-agency approach—coordinating police, courts, social services, and NGOs—has emerged to improve institutional responses. This systematic review protocol follows PRISMA-P 2015 guidelines to assess the impact of legal reforms on DV policies within police institutions. A qualitative synthesis will analyse contextual factors, with searches conducted in Web of Science, Scopus, and MEDLINE/PubMed, complemented by citation mapping via Litmaps. The PICo framework and validated using the PRESS 2015 guided the search strategy, while PRISMA-S will inform data extraction and Rayyan will manage references. Independent reviewers will assess studies, resolving disagreements with a senior researcher. The review will evaluate legal reforms’ effects on DV recidivism, their effectiveness across contexts, and perceptions of punitive versus restorative approaches. Key challenges include resource constraints, institutional resistance, and program sustainability. Findings will support policymakers in refining legislative measures and strengthening institutional responses.

Background: Enhancing performance in the public sector is closely tied to institutional structures, governance models, and the behavior of public officials. In the Judiciary, these factors significantly affect the effectiveness of court administration and justice delivery. Judicial governance is a complex and evolving concept encompassing standards and practices related to accountability, independence, resource management, and institutional performance, progressively integrating principles from public management reforms. Despite its growing relevance, the field remains fragmented, with limited evidence connecting international standards to best governance practices in judicial administration. Objective: This protocol outlines a scoping review designed to identify, map, and synthesize evidence on best practices in judicial governance, examining their relationship with the effective administration of justice and identifying research gaps to propose a future research agenda. Method: This review will follow the JBI methodology and the PRISMA-ScR guidelines. A comprehensive search will be conducted in databases such as Scopus, Web of Science, DOAJ, and JSTOR, as well as additional searches in grey literature. The PCC (Population, Concept, and Context) framework guided the eligibility criteria, and the PRESS 2015 checklist was used to validate the search strategy. The PRISMA-S checklist will inform the reporting of the search process. Studies of all designs and publication statuses will be considered, with no restrictions on language or publication date. Two reviewers will independently screen using Rayyan software, with a third reviewer resolving any disagreements. Data extraction will occur at two levels: general source information and specific content related to the review scope. Qualitative data will be analyzed using NVivo software, enabling categorization, descriptive synthesis, gap identification, and the development of a research agenda. Discussion: This scoping review aims to generate key evidence that can inform institutional standards and best governance practices to support evidence-based policymaking; while it does not assess the risk of bias, its systematic methodology and inclusion of grey literature enhance its relevance for future research and innovations in the justice sector. Through this scoping review, key evidence will generate insights that can enhance institutional standards and best practices in governance, enabling evidence-based policymaking. Although the review does not assess the risk of bias, its systematic approach and inclusion of grey literature strengthen its potential to support future research and governance innovations in the justice sector.

Background: Modern slavery is one of the most serious violations of human rights and decent work, affecting around 50 million people worldwide. Despite international regulations and initiatives such as Agenda 2030, the phenomenon persists in multiple sectors, adapting to global economic dynamics. Understanding which approaches, concepts, and evidence have been produced on modern slavery in scientific literature, from the perspective of the Sustainable Development Goals (SDGs), allows for the guidance of integrated policies, the strengthening of accountability mechanisms, and the identification of knowledge gaps. Method: This protocol describes the methodological design for conducting a scoping review that aims to systematically map the extent, nature, and gaps in scientific production on modern slavery in the context of the 2030 Agenda. The review will follow internationally recognized methodological recommendations and will be reported in accordance with the PRISMA-ScR guidelines. Searches will be conducted in multidisciplinary and specialized databases (Scopus, Web of Science, MEDLINE/PubMed, Academic Search Premier, and SocINDEX), supplemented by gray literature and institutional reports. Eligibility criteria will be defined using the PCC (Population, Concept, Context) framework. In addition, a bibliometric analysis will be performed to identify collaboration networks, research trends, and thematic clusters. Discussion: The expected result will provide insights and map academic production on modern slavery in the context of the SDGs, highlighting patterns, gaps, and regional disparities. Bibliometrics will enable the identification of research networks and key actors, providing input for public policies and future research agendas. Finally, the results will broaden the debate on sustainable development by showing how scientific literature has addressed the eradication of modern slavery, in particular target 8.7 and its connections with other goals.
