The lack of infrastructure is therefore a major challenge for agricultural development in Sub-Saharan Africa and South Asia—the regional focus of this study. It threatens food and nutrition security, depriving low-income consumers' access to healthy, affordable food and quality nutrition. Interestingly, previous studies show that physical infrastructure promotes inclusive growth and maximizes positive impacts such as improved well-being and sustainable development, and can contribute to the empowerment of women and girls. When infrastructural investments are planned, delivered, and managed using nutrition-sensitive, gender-inclusive, and responsive approaches, it can help to address barriers that impede access to nutritious diets, nutrition security, and structural inequities militating against women and girls at the household and market levels. Hence, investments in physical infrastructure could be a useful pathway for meeting various Sustainable Development Goals (SDGs 1–No Poverty, 2–Zero Hunger, 3–Good Health and Wellbeing, 5–Gender Equality, 6–Clean water and sanitation, 7–Affordable and Clean Energy, and 8–Decent Work and Economic Growth). However, few studies have examined the evidence and gaps on infrastructure's impact on nutritious diet, women's economic empowerment, and gender equality in low- and middle-income countries (LMICs) in Sub-Saharan Africa and South Asia. Evidence and gap maps are useful tools for promoting evidence-informed decision-making by making evidence and research gaps accessible to policymakers, development practitioners, and researchers. This EGM was conducted in the consultations with stakeholders. This study seeks to identify, map, and provide an overview of the existing evidence and gaps on the impact of physical infrastructure on nutritious diets, women's economic empowerment, and gender equality among low-income consumers in LMICs in sub-Saharan Africa and South Asia regions. A standardized search strategy was adapted for searching published and unpublished studies in 3 academic databases, 33 institutional websites, Google, Google Scholar, 3 existing EGMs, and 8 registries of randomized control trials and pre-analysis plans from June 2022 to September 2022. Additional papers were identified through OpenAlex in EPPI-Reviewer. We supplemented the database searches by conducting hand searches and backward citation searches in identified reviews for relevant studies. We also contacted five prominent authors in the literature for relevant completed and on-going studies for the EGM.

NDDs have a multifactorial aetiology with genetic, epigenetic, and environmental factors, including the foetal intrauterine environment. Maternal immune activation (MIA) alters the intrauterine milieu of the developing foetus, and, in animal studies, has been shown to affect the brain cytoarchitecture, neuronal circuitry and glial function of the offspring. One of the mechanisms of MIA is through cytokines that may play a crucial role in affecting foetal neurodevelopment by crossing the placenta and altering cellular programming. Antenatal cytokine concentrations have the potential to be biomarkers for children at risk of NDDs, and treating a maladaptive cytokine response may reduce the risk of NDDs in these children. Therefore, it is important to understand the scope of evidence available on the association of antenatal cytokine concentration with offspring NDDs and identify the research gaps in this field.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Inclusion Criteria</h3>\u0000 \u0000 <p>The review will consider all primary and grey literature which focuses on the review objective.

This scoping review aims to identify and map the evidence regarding the use of information and communication technologies (ICTs) in physical activity (PA) interventions for breast cancer survivors (BCS), which includes examining the types of ICTs utilized, how they are applied, and their effects on BCS' PA-related outcomes. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews Checklist (PRISMA-ScR) was used to structure this protocol. The focus of the scoping review is guided by the mnemonic PCC (Population, Concept, Context) recommended by the JBI Manual for Evidence Synthesis. PubMed, CINAHL (Ebsco), Web of Science (Clarivate), and SportDiscus (Ebsco) will be searched for peer-reviewed studies. We will include interventional studies using ICTs for PA promotion among BCS across the cancer care continuum. Our protocol incorporates information about the aims and importance of the scoping review, search strategy, inclusion/exclusion criteria, study selection, data extraction, quality assessment, and data synthesis. The total number and key characteristics of included studies will be reported in this scoping review. It will identify and map the current ICTs used in PA interventions, outline the methods and extent of their application, and summarize the related outcomes observed among BCS. Participation in PA remains insufficient among BCS despite its known benefits in lowering the risk of death and improving breast cancer prognosis. While technology-based interventions have received increased attention in recent years, there is still limited consensus within the scientific literature surrounding ICT-based PA interventions for BCS. The use of ICTs in PA interventions may promote PA among BCS and benefit their survivorship. This scoping review may lead to strategies for developing ICTs that are optimal to be used in PA interventions that benefit BCS, a large and growing population of cancer survivors. Additionally, it will identify knowledge gaps to enhance healthcare communication between healthcare practitioners and BCS using ICTs, which may promote PA and lead to improved cancer survivorship in this population.

David was a pioneering figure in the field of criminology, whose work and influence spanned decades and left an indelible mark on both academic and practical approaches to crime and justice. He has long been considered one of the most influential criminologists in history. <i>ScholarGPS</i> ranks David at the top of its list of criminology scholars for impact, productivity, and quality (see https://scholargps.com/scholars/20828811083920/david-p-farrington). Some of us used to joke that we needed a forklift to move David's printed vita, which was well over 100 pages. There are many wonderful tributes to David and his professional accomplishments, so my comments will focus more on our personal connections (e.g., see J. W. Thulborn's tribute, “David P. Farrington, O. B. E., Distinguished Criminologist and Scholar 1944–2024” at https://www.crim.cam.ac.uk/news/david-p-farrington-obe-distinguished-criminologist-and-scholar-1944-2024. Those who want to better understand David's career pathway, at least through 1997, may appreciate this interview of him by Rolf Leiber for the American Society of Criminology Oral History of Criminology Project at: https://asc41.org/oral-history/david-farrington-interviewed-by-rolf-loeber-november-20-1997/).</p><p>One of my first interactions with David came when I was doing my dissertation in the mid-1990s. I reached out to him, as he was one of the leading proponents of using randomized controlled trials (RCTs) to test criminological interventions (Farrington <span>1983</span>), and he was excited to hear that my research focused on individual-level RCTs that tested a strategy to reduce criminal offending (Petrosino <span>1997</span>). He sent me relevant articles and reports, and periodically would send encouraging notes pushing me to finish the dissertation. Later, after I got the doctorate, I put in a proposal to Oxford University Press for a book based on my dissertation research. I later learned that David was a peer reviewer and the strongest advocate for Oxford to contract with me to write it. Unfortunately, my progress stalled on this book idea when other work commitments got in the way. David pushed me to finish, saying “it was the thing that would last,” and I wish I had listened to him, as I remain “bookless” as an author, all these years later.</p><p>We finally crossed paths in person in 1998 when I got involved in preliminary efforts to launch the Campbell Collaboration (Petrosino <span>2013</span>).
