Review
Sustainability certification schemes such as FAIRTRADE, FLO, WFTO and FT-USA have gained increasing markets. The significant growth of the fair trade (FT) movement in the last decades draws attention to ethical consumption. FT's aim at improving the livelihoods of producers in developing countries and promotion of social change is considered a model that shows the benefits of trade to development. Although conveying a large number of publications, important questions about the movement remain under-explored. The literature is prolific on coffee, cacao, flowers, wine, and gold. In contrast, the engagement with staple foods - a prominent globally traded food category - seems minor. The primary objective of this review was to map the existing literature about FT and staple foods; then, to investigate the role of staple foods in the FT movement. The search strategy was designed to retrieve publications on the intersection of FT and staple foods. To date, there is no review about FT and staple foods nexus. Our systematic review addressed this gap considering FT as an alternative capable of addressing unsustainable food consumption and production impacts. Our research protocol included keywords searching across four databases, screening, and comparative analysis. From 283 documents retrieved, 49 were deemed relevant to reflect the role of staple foods in the FT movement. This systematic review discusses challenges and opportunities for the FT model to further engage with staples and recommends improvement of its environmental credentials. The present study can contribute by informing decision makers, policy makers, businesses, NGOs, producers, and consumers.

Review
Diabetes is a serious chronic metabolic disease that causes complications over time, bringing serious public health challenges that affect different countries across the world. The current clinical drugs for diabetes may lead to adverse effects such as hypoglycemia and liver and abdominal distension and pain, which prompt people to explore new treatments for diabetes without side effects. The research objective of this review article is to systematically review studies on vitamins and diabetes and to explain their possible mechanism of action, as well as to assess the role of vitamins as drugs for the prevention and treatment of diabetes. To achieve our objective, we searched scientific databases in PubMed Central, Medline databases and Web of Science for articles, using "vitamin" and "diabetes" as key words. The results of numerous scientific investigations revealed that vitamin levels were decreased in humans and animals with diabetes, and vitamins show promise for the prevention and/or control of diabetes through anti-inflammation, antioxidation and the regulation of lipid metabolism. However, a few studies showed that vitamins had no positive effect on the development of diabetes. Currently, studies on vitamins in the treatment of diabetes are still very limited, and there are no clinical data to clarify the dose-effect relationship between vitamins and diabetes; therefore, vitamins are not recommended as routine drugs for the treatment of diabetes. However, we still emphasize the great potential of vitamins in the prevention and treatment of diabetes, and higher quality studies are needed in the future to reveal the role of vitamins in the development of diabetes.

Review
. This work aimed to synthesize the results of recent meta-analysis focusing on polymorphism in inflammatory mediators and its relation with the risk of periodontitis development. . A systematic search was conducted using databases for publications prior to October 2016. Three examiners extracted data from articles with a clear association between polymorphisms in the inflammatory mediator gene and the development of periodontitis through meta-analysis using the fixed or randomized statistical models to calculate the Odds Ratio with values of < 0.05 considered significant. . A total of 13 meta-analysis articles with 25 polymorphisms in seven interleukins (IL-1A, IL-1B, IL-4, IL-6, IL-8, IL-10, and IL-18), three cellular receptors (Fc receptors: FCGR2A, FCGR3A, and FCGR3B), and five inflammatory mediators (COX-2, MMP-2, MMP-3, MMP-8, and MMP-9), with a total of 71,531 participants, approaching different classifications of the disease. . The study demonstrated that polymorphisms in the IL-1A, IL-1B, IL-6, IL-10, MMP-3 (chronic form), and MMP-9 (chronic form) polymorphisms were significantly associated with the risk of developing periodontitis, whereas other polymorphisms in the IL-4, IL-8, IL-18, Fc, COX-2, MMP-2, MMP-3 (aggressive), MMP-8, and MMP-9 (aggressive) polymorphisms had no significant association with risk of developing periodontitis.

Review
BACKGROUND
A chatbot is a computer program that is designed to simulate conversation with humans. Chatbots may offer rapid, responsive, and private contraceptive information; counseling; and linkages to products and services, which could improve contraceptive knowledge, attitudes, and behaviors.
OBJECTIVE
This review aimed to systematically collate and interpret evidence to determine whether and how chatbots improve contraceptive knowledge, attitudes, and behaviors. Contraceptive knowledge, attitudes, and behaviors include access to contraceptive information, understanding of contraceptive information, access to contraceptive services, contraceptive uptake, contraceptive continuation, and contraceptive communication or negotiation skills. A secondary aim of the review is to identify and summarize best practice recommendations for chatbot development to improve contraceptive outcomes, including the cost-effectiveness of chatbots where evidence is available.
METHODS
We systematically searched peer-reviewed and gray literature (2010-2022) for papers that evaluated chatbots offering contraceptive information and services. Sources were included if they featured a chatbot and addressed an element of contraception, for example, uptake of hormonal contraceptives. Literature was assessed for methodological quality using appropriate quality assessment tools. Data were extracted from the included sources using a data extraction framework. A narrative synthesis approach was used to collate qualitative evidence as quantitative evidence was too sparse for a quantitative synthesis to be carried out.
RESULTS
We identified 15 sources, including 8 original research papers and 7 gray literature papers. These sources included 16 unique chatbots. This review found the following evidence on the impact and efficacy of chatbots: a large, robust randomized controlled trial suggests that chatbots have no effect on intention to use contraception; a small, uncontrolled cohort study suggests increased uptake of contraception among adolescent girls; and a development report, using poor-quality methods, suggests no impact on improved access to services. There is also poor-quality evidence to suggest increased contraceptive knowledge from interacting with chatbot content. User engagement was mixed, with some chatbots reaching wide audiences and others reaching very small audiences. User feedback suggests that chatbots may be experienced as acceptable, convenient, anonymous, and private, but also as incompetent, inconvenient, and unsympathetic. The best practice guidance on the development of chatbots to improve contraceptive knowledge, attitudes, and behaviors is consistent with that in the literature on chatbots in other health care fields.
CONCLUSIONS
We found limited and conflicting evidence on chatbots to improve contraceptive knowledge, attitudes, and behaviors. Further research that examines the impact of chatbot interventions in comparison with alternative technologies, acknowledges the varied and changing nature of chatbot interventions, and seeks to identify key features associated with improved contraceptive outcomes is needed. The limitations of this review include the limited evidence available on this topic, the lack of formal evaluation of chatbots in this field, and the lack of standardized definition of what a chatbot is.

Jornal de Pediatria 2015To review the literature that addresses the relationship between prematurity, birth weight, and development of language in Brazilian children. (Review)
Review
OBJECTIVE
To review the literature that addresses the relationship between prematurity, birth weight, and development of language in Brazilian children.
SOURCES
A systematic review of studies published between 2003 and 2012 in English and Portuguese and indexed in PubMed, LILACS, and SciELO. The following key words were used in the searches: Prematuro, Prematuridade, Linguagem, Prematurity, Language, Speech-Language Pathology. Fifty-seven articles were retrieved, 13 of which were included in the systematic review.
SUMMARY OF THE FINDINGS
The results showed an association between prematurity, low birth weight, and language development. In studies that made comparisons between preterm and term infants, there was evidence that preterm infants had poorer performance on indicators of language. It was also observed that children born with lower birth weight had a poorer performance on measures of language when compared to children with higher weight and closer to 37 weeks of gestational age. Regarding the type of language assessed, expression proved to be more impaired than reception. Higher parental education and family income were indicated as protective factors for the development of language. Conversely, lower birth weight and higher degree of prematurity emerged as risk factors.
CONCLUSIONS
Preterm birth and low birth weight poses risks for the language development of children, especially in the first years of life. Therefore, it is essential that pediatricians are aware of the language development of these children to ensure proper treatment.

Review
The purpose of this systematic review is to assess the associations among education, income and dietary pattern (DP) in children and adolescents from high, medium and low human development countries (HHDC, MHDC and LHDC, respectively). Observational studies that evaluated the association between family income or education with the DP are obtained through electronic database searches. Forty articles are selected for review. In HHDC, education is inversely associated with "unhealthy" DP and positively associated with "healthy" DP. In cross-sectional studies from HHDC, higher income is negatively associated with "unhealthy" DP. In MHDC, there is no association between the socioeconomic variables (SE) and the DPs, although, in some studies, the unhealthy diet is positively associated with SE. Only one study conducted in LHDC showed an inverse association between income/education with "unhealthy" DP and there is no association between the SE and "healthy" DP. In conclusion, children and adolescents living in HHDC with high parental education tend to have a healthier diet. In MHDC, although an unhealthy diet is found among the high-income and educated population, the associations are not clear. Additional research is needed to clarify the associations between income and education with "unhealthy" and "healthy" DPs in MHDC and LHDC.

BACKGROUND
Ultra-processed food (UPF) consumption continues to increase worldwide. However, evidences from meta-analyses are limited regarding the effects on cardiovascular events (CVEs).
METHODS
A meta-analysis was performed to assess the dose-response relationship of UPF consumption and CVEs risk (including the morbidity and mortality of cardiovascular causes, and myocardial infarction, stroke, transient ischemic attack, coronary intervention). Databases (PubMed, EMBASE, Cochrane Library, and Web of Science) were searched for observational studies published in English language up to October 24, 2023. Generalized least squares regression and restricted cubic splines were used to estimate the linear/nonlinear relationship. PROSPERO CRD 42023391122.
FINDINGS
Twenty studies with 1,101,073 participants and 58,201 CVEs cases with a median follow-up of 12.2 years were included. A positive linear relationship between UPF intake and CVEs risk was identified. In addition, positive correlation between coronary heart disease and UPF consumption in terms of daily serving and daily energy proportion. No significant association of UPF consumption with the risk of cerebrovascular disease was observed. Briefly, 10% increase of UPF by daily weight proportion was associated with a 1.9% increase of CVEs risk (RR = 1.019; 95% CI, 1.007-1.031; = 0.002), an additional daily serving corresponding to 2.2% CVEs risk increase (RR = 1.022; 95% CI, 1.013-1.031; < 0.001), and 10% increase by daily energy proportion corresponding to 1.6% CVEs risk increase (RR = 1.016; 95% CI, 1.002-1.030; = 0.022).
INTERPRETATION
UPF consumption were associated with a higher risk of CVEs in the positive linear relationship. Our findings highlight the importance of minimizing UPF consumption for cardiovascular health and might be help to pursue public health policies in control of UPF consumption.

Review
BACKGROUND
Physician leadership development programs typically aim to strengthen physicians' leadership competencies and improve organizational performance. We conducted a systematic review of medical literature on physician leadership development programs in order to characterize the setting, educational content, teaching methods, and learning outcomes achieved.
METHODS
Articles were identified through a search in Ovid MEDLINE from 1950 through November 2013. We included articles that described programs designed to expose physicians to leadership concepts, outlined teaching methods, and reported evaluation outcomes. A thematic analysis was conducted using a structured data entry form with categories for setting/target group, educational content, format, type of evaluation and outcomes.
RESULTS
We identified 45 studies that met eligibility criteria, of which 35 reported on programs exclusively targeting physicians. The majority of programs focused on skills training and technical and conceptual knowledge, while fewer programs focused on personal growth and awareness. Half of the studies used pre/post intervention designs, and four studies used a comparison group. Positive outcomes were reported in all studies, although the majority of studies relied on learner satisfaction scores and self-assessed knowledge or behavioral change. Only six studies documented favorable organizational outcomes, such as improvement in quality indicators for disease management. The leadership programs examined in these studies were characterized by the use of multiple learning methods, including lectures, seminars, group work, and action learning projects in multidisciplinary teams.
DISCUSSION
Physician leadership development programs are associated with increased self-assessed knowledge and expertise; however, few studies have examined outcomes at a system level. Our synthesis of the literature suggests important gaps, including a lack of programs that integrate non-physician and physician professionals, limited use of more interactive learning and feedback to develop greater self-awareness, and an overly narrow focus on individual-level rather than system-level outcomes.

Many nutrition programs include classroom-based education. Schoolteachers are relied upon to deliver these programs despite gaps in nutrition education motivation, knowledge, and self-efficacy. Teacher professional development (PD) for these nutrition education programs has been identified as a strategy for improving program effectiveness, yet many interventions do not include a PD component and still fewer describe it. A literature search was conducted between January and February 2017; articles were collected from PubMed, ERIC, and EBSCOhost. Article inclusion criteria were as follows: 1) published in an English-language peer-reviewed or scholarly journal, 2) published after 2000, 3) empirical research, 4) research conducted in a K-12 classroom, 5) research included nutrition education component, and 6) program delivered by a classroom teacher. Twenty-seven interventions were identified. A team of 2 researchers performed content analysis based on an evidence-based set of 7 PD components to assess if and how these components were incorporated before, during, or after program implementation. Little information was provided that described the role of teacher PD in the course of delivering nutrition education in classroom-based programs. The most common elements of PD described in the literature were the time spent in PD and follow-up with instructors during or after program implementation. There was a notable lack of methodologic description of teacher PD, and this limited reporting may decrease researchers' ability to work with teachers in a consistent and effective manner.

INTRODUCTION
Providing postgraduate rural training programs has been recognised as central for successful recruitment and retention of medical workforce. While there have been many documented cases of rural training program development, documented program outcome evaluations are few. This review investigated how postgraduate training and educational programs for rural and remote medicine are evaluated worldwide. Through the use of a systematic review, the study explored three questions: 'What are the outcomes of postgraduate rural and remote training programs worldwide?', 'How are the program evaluations conducted?' and 'What evaluation models and approaches are used in evaluating the effectiveness of these training programs?'
METHODS
A qualitative synthesis was undertaken of evaluations of postgraduate rural training programs published in the English language in medical education journals. The study involved pooling quantitative and mixed-methods research data and findings from qualitative studies, which were aggregated, integrated and interpreted. PubMed, PsycINFO, ERIC and Web of Science databases were searched to identify studies that satisfy the search criteria.
RESULTS
Of the 1297 articles identified through the database search, 26 studies were included in the analysis. Most of the evidence from the studies consists of descriptive studies with some longitudinal tracking programs and cohort studies. Nine themes were identified: practice location after training completion; training location and decentralised model; educational aspects; incentives, political contexts and regulations; personal, social and cultural issues; professional development; rural orientation and community engagement; support system; and gender and racial issues. Key outcomes were analysed and cross-validated against the 2020 WHO guideline on health workforce development, attraction, recruitment and retention in rural and remote areas. These studies' most frequent evaluation methods were surveys, followed by interviews, questionnaires and secondary data from existing databases. Methodological characteristics, the relationship between rural background and program outcomes, and implications for decentralised training, telehealth and tele-assessment during the COVID-19 pandemic are discussed. Analysis from the key outcomes suggests evaluation as a strategy to uncover outcomes in postgraduate rural and remote training and medical education.
CONCLUSION
Regardless of the similar outcomes, the program evaluations implemented and the robustness of evidence vary across programs and medical schools. The absence of solid evaluation designs and their alignment to the program objectives will lessen the strengths of evidence. Better quality research and evaluation design, objective settings, qualitative inquiry to uncover the contexts, and developing appropriate indicators and benchmarks for monitoring and evaluating strategies must be considered during program development and implementation.
