Background: In the last decades, an increasing incidence of testicular cancer has been observed in several countries worldwide. Although mortality rates have been variable in many countries, little information is available from Latin America and the Caribbean (LAC). Therefore, we examined mortality trends of testicular cancer in the last two decades. Methods: Age-standardized mortality rates (ASMR) of testicular cancer per 100,000 men-years were estimated using the World Health Organization mortality database from 1997 to 2019. We examined the mortality trends and computed annual percent change (APC) for all ages and the following age groups, 15–29, 30–44, 15–44, and ≥ 45 years. Results: Ten countries had mortality rates greater than 0.43 per 100,000 men, with the highest rates for Chile, Mexico, and Argentina. Significant increases in mortality rates were observed in Argentina, Brazil Colombia, and Mexico in all ages, and < 45 years, while Colombia, Ecuador, Mexico, and Peru reported significant downward trends in males aged ≥ 45 years. Only Chile showed significant decreases for all ages and age groups studied. Conclusion: Mortality by testicular cancer increased among LAC countries in males of all ages and across age groups. A reduction in mortality rates was observed only in Chilean males of all ages and in men ≥ 45 years in several countries. Strengthening of early detection among symptomatic males may decrease the mortality by this neoplasm. [ABSTRACT FROM AUTHOR]

Background: Aedes aegypti, the vector of arboviral diseases such as dengue and Zika virus infections, is difficult to control. Effective interventions must be practicable, comprehensive, and sustained. There is evidence that community participation can enhance mosquito control. Therefore, countries are encouraged to develop and integrate community-based approaches to mosquito control to mitigate Aedes-borne infectious diseases (ABIDs). Health professionals must understand the contexts motivating individuals’ behaviour to improve community participation and promote behavioural change. Therefore, this study aimed to determine how contexts shaped individuals’ protective behaviours related to ABIDs in Curaçao. Methods: From April 2019 to September 2020, a multi-method qualitative study applying seven (n = 54) focus group discussions and twenty-five in-depth interviews with locals was performed in Curaҫao. The study was designed based on the Health Belief Model (HBM). Two cycles of inductive and deductive coding were employed, and Nvivo software was used to manage and analyse the data. Results: In this study, low media coverage (external cue to action) and limited experience with the symptoms of ABIDs (internal cue to action) were linked with a low perceived susceptibility and severity of ABIDs (low perceived threat). The low perceived threat was linked with reduced health-seeking behaviour (HSB) to prevent and control ABIDs. We also found that the perceived barriers outweigh the perceived benefits of ABID prevention and control interventions, obstructing HSB. On the one hand, insufficient knowledge reduced self-efficacy but contrary to expected, having good knowledge did not promote HSB. Lastly, we found that our participants believe that they are responsible for preventing ABIDs (internal locus of control) but at the same time indicated that their success depends on the efforts of the community and the health system (external locus of control). Conclusions: This study used the HBM to explain individual changes in HSB concerning ABIDs prevention and control in Curaçao. We can conclude that the perceived threat (perceived susceptibility and severity) and perceived barriers played an essential role in changing HSB. Health professionals must consider these two concepts' implications when designing a bottom-up approach for ABIDs control; otherwise, community participation will remain minimal.

Background: Breast cancer is among the leading cause of cancer-related mortality among Latin American and Caribbean (LAC) women, but a comprehensive and updated analysis of mortality trends is lacking. The objective of this study was to determine the breast cancer mortality rates between 1997 and 2017 for LAC countries and predict mortality until 2030. Methods: We retrieved breast cancer deaths across 17 LAC countries from the World Health Organization mortality database. Age-standardized mortality rates per 100,000 women-years were estimated. Mortality trends were evaluated with Joinpoint regression analyses by country and age group (all ages, < 50 years, and ≥ 50 years). By 2030, we predict number of deaths, mortality rates, changes in population structure and size, and the risk of death from breast cancer. Results: Argentina, Uruguay, and Venezuela reported the highest mortality rates throughout the study period. Guatemala, El Salvador, and Nicaragua reported the largest increases (from 2.4 to 2.8% annually), whereas Argentina, Chile, and Uruguay reported downward trends (from − 1.0 to − 1.6% annually). In women < 50y, six countries presented downward trends and five countries showed increasing trends. In women ≥ 50y, three countries had decreased trends and ten showed increased trends. In 2030, increases in mortality are expected in the LAC region, mainly in Guatemala (+ 63.0%), Nicaragua (+ 47.3), El Salvador (+ 46.2%), Ecuador (+ 38.5%) and Venezuela (+ 29.9%). Conclusion: Our findings suggest considerable differences in breast cancer mortality across LAC countries by age group. To achieve the 2030 sustainable developmental goals, LAC countries should implement public health strategies to reduce mortality by breast cancer. [ABSTRACT FROM AUTHOR]

Politics as the exercise of power always influence public policies-which reflects the multifaceted nature of decision-making-but "using politics" as a motivation for self-serving interests of government leaders and their allies poses problems. This article reviews the impacts of COVID-19 on health systems of the Latin American and Caribbean region from a political lens. We highlight the overriding influence of politics in health policies, weak governance structures that became compromised, exacerbation of corruption, and breakdowns in the communication and trust between governments and their citizens. There are many factors that did not work well-or as expected. For instance, the poor predictive ability of the Global Health Security Index, which showed that pre-pandemic assessments were deeply naive to how health systems evidence and expertise are uniquely vulnerable to politics. We argue that there is an urgent need to rethink health policy and systems frameworks-including metrics-at national and global level. There is also a need for new global health governance arrangements. The expected solidarity and collaboration among countries was trumped by the rich countries practice of gauging essential resources and vaccines and applying health diplomacy to the rest of the world, and the unchecked power of commercial corporations producing essential medical supplies and vaccines., (© 2024.

Background: Small island developing states (SIDS) have particular mental health system needs due to their remoteness and narrow resource base. We conducted situational analyses to support mental health system strengthening in six SIDS: Anguilla, Bermuda, British Virgin Islands, Cayman Islands, Montserrat and Turks and Caicos Islands. Methods: The situational analyses covered five domains: 1. Socio-economic context and burden of mental disorders, 2. Leadership and governance for mental health 3. Mental health and social care services 4. Strategies for promotion and prevention in mental health and 5. Information systems, evidence and research for mental health. First, a desk-based exercise was conducted, in which data was drawn from the public domain. Second, a field visit was conducted at each site, comprising visits to facilities and consultation meetings with key stakeholders. Results: Our key findings were 1. Despite most of these SIDS being high-income economies, social inequalities within states exist. There was no population-level data on mental health burden. 2. All SIDS have a mental health policy or plan, but implementation is typically limited due to lack of funds or staff shortages. There was minimal evidence of service user involvement in policy or service development. 3. All SIDS have a specialist, multi-disciplinary mental health workforce, however Montserrat and Anguilla rely on visiting psychiatrists. Child and adolescent and dedicated crisis intervention services were found in only two and one SIDS respectively. A recovery-oriented ethos was not identified in any SIDS. 4. Mental illness stigma was prevalent in all SIDS. Promotion and prevention were objectives of mental health strategies for all SIDS, however activities tended to be sporadic. No mental health non-Governmental organisations were identified in three SIDS. 5. Health information systems are generally underdeveloped, with paper-based systems in three SIDS. There has been no rigorous local mental health research. Conclusion: Cross-cutting recommendations include: to develop mental health action plans that include clear implementation indicators; to facilitate community surveys to ascertain the prevalence of mental disorders; to explore task-sharing approaches to increase access to primary mental health care; and to develop programmes of mental health promotion and prevention.

Background: Chronic Obstructive Pulmonary Disease (COPD) remains one of the leading causes of morbidity and mortality worldwide, and its epidemiology in Latin America and the Caribbean is not well described. The aim of this study was to evaluate the prevalence and incidence of COPD in Latin America and the Caribbean.Methods: We searched systematically in Web of Science (WoS)/Core Collection, WoS/MEDLINE, WoS/Scielo, Scopus, PubMed, and Embase from 2010 to 2021. Studies assessing the prevalence and incidence of COPD according to the GOLD classification were included. The overall prevalence of COPD was calculated as a function of the general population using a random-effects model.Results: 20 studies (19 cross-sectional and 1 cohort) met the inclusion criteria. The prevalence of COPD in the general population older than 35 years was 8.9%. The prevalence in men was 13.7% and in women 6.7%. The prevalence in smokers and ex-smokers was 24.3%. The incidence in the general population of COPD according to one study was 3.4% at 9 years of follow-up.Conclusions: COPD is prevalent in Latin America, especially in men and in smokers and ex-smokers. Further prevalence and incidence studies in the general population are needed, as well as health policies and strategies to address the disease. [ABSTRACT FROM AUTHOR]

Internationally, there is a wealth of research suggesting that many children and young people experience mental health problems. However, the evidence from low- and middle-income countries and developing nations is generally limited. This scoping review aimed to add to the body of evidence by providing an overview of the available research literature on children and young people's (CYP's) mental health in the English-speaking Caribbean region. Seven key online academic databases and grey literature sources were searched until January 2021. Records were screened against predefined criteria and suitable articles retrieved. Relevant information was then charted and summarized. All stages of the review were informed by expert consultations. Ninety-six articles from 7901 records met the inclusion criteria. Most of the studies were conducted in Jamaica, Trinidad and Tobago and Barbados while fewer studies reported findings from St Lucia, The Bahamas and St Kitts and Nevis. Research funding was not frequently reported, and participants were predominantly recruited in education settings. There was a substantial focus on depressive symptoms and behaviour problems. Little or no research was available for younger children (< 12), complex clinical cases or commonly under-represented groups. Four unique interventions were identified of which one intervention showed no significant impact on CYP. Among the commonly used outcome measures only the Jamaican Youth Checklist (teacher-reported), Beck Depression Inventory-II, Brief Screen for Depression, Trinidad and Tobago Youth Survey and Minnesota Multiphasic Personality Inventory had evidence for psychometric validity within this population. We discuss future directions, implications and recommendations for research, practice, policy and training. [ABSTRACT FROM AUTHOR]

Background: Much has been said by actors from different fields and perspectives about the manifold changes in world affairs triggered by the COVID-19 pandemic. In this context, it is to be expected that there will be impacts on long-standing partnerships such as the one between the European Union and the Community of Latin American and Caribbean Countries. However, few studies have demonstrated these impacts, either empirically, by uncovering their specificities or from a historical perspective, to allow for a reasonable methodological comparison of the patterns used to define the partnership and that have changed or have been affected in some way by the pandemic., Results: Through an in-depth qualitative assessment of primary and secondary sources, this article contributes to this research gap. It analyzes the patterns and changes or impacts in light of two strands of behavior that can make sense of EU-CELAC health cooperation-revisionist or reformist. The findings show an economy-driven health agenda as a new pattern of cooperation, which derives from EU reformist behavior after the pandemic., Conclusions: The EU power to enforce its priorities in the context of health cooperation with CELAC is the main factor that will define how (and not just which) competing interests and capacities will be accommodated. The relevance of the study to the fields of global governance for health, interregional health cooperation and EU foreign policy is threefold. It shows us i.how two more international regimes are easily intertwined with health-trade and intellectual property-with the potential to deepen asymmetries and divergences even between long-standing strategic partners; ii.contrary to the idea that reformist behaviors are only adopted by actors who are dissatisfied with the status quo, the study shows us that the reformist actor can also be the one who has more material power and influence and who nevertheless challenges the success of cooperation in the name of new priorities and the means to achieve them; and iii.how the EU will find it difficult to operationalize its new priorities internally, among states and private actors, and with those of CELAC, given the history of intense disputes over health-related economic aspects., (© 2024.

Background: Accreditation and regulation are meant for quality assurance in higher education. However, there is no guarantee that accreditation ensures quality improvement. The accreditation for Caribbean medical schools varies from island to island, and it could be mandatory or voluntary, depending on local government requirements. Caribbean medical schools recently attained accreditation status to meet the Educational Commission for Foreign Medical Graduates (ECFMG) requirements by 2024. Literature suggests that accreditation impacts ECFMG certification rates and medical schools' educational processes. However, no such study has examined accreditation's impact on continuous quality improvement (CQI) in medical schools. This study aims to gather the perceptions and experiences of faculty members and academic leaders regarding the impact of accreditation on CQI across Caribbean medical schools., Methods: This qualitative phenomenological study inquiries about the perceptions and experiences of faculty and academic leaders regarding accreditation's impact on CQI. Purposive and snowball sampling techniques were used. Participants were interviewed using a semi-structured interview method. Fifteen participants were interviewed across ten Caribbean medical schools representing accredited medical schools, accreditation denied medical schools, and schools that never applied for accreditation. Interviews were audio recorded, and thematic data analysis was conducted., Results: Thematic analysis yielded six themes, including accreditation and CQI, CQI irrespective of accreditation, faculty engagement and faculty empowerment in the CQI process, collecting and sharing data, ECFMG 2024 requirements, and organizational structure of CQI., Conclusions: There is ongoing quality improvement at Caribbean medical schools, as perceived by faculty members and academic leaders. However, most of the change process is happening because of accreditation, and the quality improvement is due to external push such as accreditation rather than internal motivation. It is recommended that Caribbean medical schools promote internal quality improvement irrespective of accreditation and embrace the culture of CQI., (© 2024. The Author(s).)

Background: Ticks are obligate hematophagous ectoparasites involved in transmitting viruses of public health importance. The objective of this work was to identify the Jingmen tick virus in hard ticks from the Colombian Caribbean, an arbovirus of importance for public health., Methods: Ticks were collected in rural areas of Córdoba and Cesar, Colombia. Taxonomic identification of ticks was carried out, and pools of 13 individuals were formed. RNA extraction was performed. Library preparation was performed with the MGIEasy kit, and next-generation sequencing (NGS) with MGI equipment. Bioinformatic analyses and taxonomic assignments were performed using the Galaxy platform, and phylogenetic analyses were done using IQ-TREE2., Results: A total of 766 ticks were collected, of which 87.33% (669/766) were Rhipicephalus microplus, 5.4% (42/766) Dermacentor nitens, 4.2% (32/766) Rhipicephalus linnaei, and 3.0% (23/766) Amblyomma dissimile. Complete and partial segments 1, 2, 3, and 4 of Jingmen tick virus (JMTV) were detected in the metatranscriptome of the species R. microplus, D. nitens, and A. dissimile. The JMTVs detected are phylogenetically related to JMTVs detected in Aedes albopictus in France, JMTVs detected in R. microplus in Trinidad and Tobago, JMTVs in R. microplus and A. variegatum in the French Antilles, and JMTVs detected in R. microplus in Colombia. Interestingly, our sequences clustered closely with JMTV detected in humans from Kosovo., Conclusions: JMTV was detected in R. microplus, D. nitens, and A. dissimile. JMTV could pose a risk to humans. Therefore, it is vital to establish epidemiological surveillance measures to better understand the possible role of JMTV in tropical diseases., (© 2024.

Background: Health literacy (HL) impacts people's health and well-being. In Latin America and the Caribbean (LAC), there are no general estimates of the prevalence of low HL. This study aimed to estimate the prevalence of low HL among citizens of LAC and identify the tools used to measure it., Methods: We included observational studies quantifying the prevalence of low HL in people living in LAC. We searched PubMed, CINAHL, EMBASE, ERIC, LILACS, PsycINFO, Redalyc, SciELO, Web of Science, PQDT, and the reference lists of the included studies in June 2023. Two reviewers independently conducted the selection, extraction, and risk of bias assessment using the JBI Critical Appraisal Tools. Meta-analysis of proportions using random effects models was used to summarize the prevalence of low HL estimated. This prevalence was measured in each study using different classification methods: word recognition items, reading and numeracy comprehension items, and self-reported comprehension items., Results: Eighty four studies involving 23,914 participants from 15 countries were included. We identified 23 tools to assess HL, and most of the studies were carried out in health services. The pooled prevalence of low HL were 44.02% (95%CI: 36.12-52.24) for reading and numeracy comprehension items, 50.62% (95%CI: 41.82-59.39) for word recognition items, and 41.73% (95%CI: 31.76-52.43) for self-reported comprehension items., Conclusion: Despite the variability in the prevalence of low HL and a diversity of tools, the average of low HL is of concern. Almost half of the participants in the included studies have low HL. Most of the studies targeted users of healthcare services. Further research investigating the prevalence of low HL in the general population and actions focused on health education, communication, and information are necessary., Trial Registration: PROSPERO (CRD42021250286)., (© 2024.

Background: Vector-borne diseases (VBDs) such as dengue, chikungunya, and Zika pose a significant challenge to health systems in countries they affect, especially countries with less developed healthcare systems. Therefore, countries are encouraged to work towards more resilient health systems. This qualitative study aims to examine the performance of the health system of the Dutch Caribbean island of Curaҫao regarding the prevention and control of VBDs in the last decade by using the WHO health system building blocks. Methods: From November 2018 to December 2020, a multi-method qualitative study was performed in Curaçao, applying content analysis of documents (n = 50), five focus group discussions (n = 30), interviews with experts (n = 11) and 15 observation sessions. The study was designed based on the WHO framework: health system building blocks. Two cycles of inductive and deductive coding were employed, and Nvivo software was used to analyse the data. Results: This study's data highlighted the challenges (e.g. insufficient oversight, coordination, leadership skills, structure and communication) that the departments of the health system of Curaҫao faced during the last three epidemics of VBDs (2010–2020). Furthermore, low levels of collaboration between governmental and non-governmental organisations (e.g. semi-governmental and private laboratories) and insufficient capacity building to improve skills (e.g. entomological, surveillance skills) were also observed. Lastly, we observed how bottlenecks in one building block negatively influenced other building blocks (e.g. inadequate leadership/governance obstructed the workforce's performance). Conclusions: This study uncovers potential organisational bottlenecks that have affected the performance of the health system of Curaҫao negatively. We recommend starting with the reinforcement of oversight of the integrated vector management programme to ensure the development, implementation and evaluation of related legislation, policies and interventions. Also, we recommend evaluating and reforming the existing administrative and organisational structure of the health system by considering the cultural style, challenges and barriers of the current health system. More efforts are needed to improve the documentation of agreements, recruitment and evaluation of the workforce's performance. Based on our findings, we conceptualised actions to strengthen the health system's building blocks to improve its performance for future outbreaks of infectious diseases. [ABSTRACT FROM AUTHOR]

Background: Maternal and child health have shown important advances in the world in recent years. However, national averages indicators hide large inequalities in access and quality of care in population subgroups. We explore wealth-related inequalities affecting health coverage and interventions in reproductive, maternal, newborn, and child health in Latin America and the Caribbean.Methods: We analyzed representative national surveys from 15 countries conducted between 2001 and 2016. We estimated maternal-child health coverage gaps using the Composite Coverage Index - a weighted average of interventions that include family planning, maternal and newborn care, immunizations, and treatment of sick children. We measured absolute and relative inequality to assess gaps by wealth quintile. Pearson's correlation coefficient was used to test the association between the coverage gap and population attributable risk.Results: The Composite Coverage Index showed patterns of inequality favoring the wealthiest subgroups. In eight countries the national coverage was higher than the global median (78.4%; 95% CI: 73.1-83.6) and increased significantly as inequality decreased (Pearson r = 0.9; p < 0.01).Conclusions: There are substantial inequalities between socioeconomic groups. Reducing inequalities will improve coverage indicators for women and children. Additional health policies, programs, and practices are required to promote equity. [ABSTRACT FROM AUTHOR]

Primary health care (PHC) has increased in global relevance as it has been demonstrated to be a useful strategy to promote community access to health services. Multilateral organizations and national governments have reached a consensus regarding the basic principles of PHC, but the application of these varies from country to country due to the particularities of local health systems.This article aims to review and summarize PHC strategies and the configuration of health networks in Latin American and Caribbean countries.The review was carried out using keywords in at least 9 databases. Papers in languages other than English, Portuguese, and Spanish were excluded, while non-refereed articles and regional gray literature were incorporated. As a result, 1,146 papers were identified. After three instances of analysis, 142 articles were selected for this investigation. Data were analyzed according to an analysis by theme.The evidence collected on health reforms in the region reflects the need to intensify care strategies supported by PHC and care networks. These must be resilient to changes in the population's needs and must be able to adapt to contexts of epidemiological accumulation., (© 2024. The Author(s).)

Background: The role of human resources for health in the operation of health systems is crucial. However, training and incorporating them into institutions is a complex process due to the continuous misalignment between the supply and demand of health personnel. Taking the case of the Latin American and Caribbean region countries, this comment discusses the relationship between the availability of human resources for health and the maternal mortality ratio for the period 1990-2021. It proposes the need to resume planning exercises from a systemic perspective that involves all areas of government and the private sector linked to the training and employment of health workers., Main Text: We used secondary data from a global source to show patterns in the relationship between these two aspects and identify gaps in the Latin American and Caribbean regions. The results show enormous heterogeneity in the response of regional health systems to the challenge of maternal mortality in the region. Although most countries articulated specific programs to achieve the reduction committed by all countries through the Millennium Development Goals, not all had the same capacity to reduce it, and practically none met the target. In addition, in the English Caribbean countries, we found significant increases in the number of health personnel that do not explain the increases in the maternal mortality rate during the period., Conclusions: The great lesson from the data shown is that some countries could articulate responses to the problem using available resources through effective strategies, considering the specific needs of their populations. Although variations in maternal mortality rate cannot be explained solely through the provision of health personnel, it is important to consider that it is critical to find new modalities on how human resources for health could integrate and create synergies with other resources to increase systems capacity to deliver care according to conditions in each country., (© 2024.

Long-read sequencing is revolutionizing de-novo genome assemblies, with continued advancements making it more readily available for previously understudied, non-model organisms. Stony corals are one such example, with long-read de-novo genome assemblies now starting to be publicly available, opening the door for a wide array of 'omics-based research. Here we present a new de-novo genome assembly for the endangered Caribbean star coral, Orbicella faveolata, using PacBio circular consensus reads. Our genome assembly improved the contiguity (51 versus 1,933 contigs) and complete and single copy BUSCO orthologs (93.6% versus 85.3%, database metazoa&#95;odb10), compared to the currently available reference genome generated using short-read methodologies. Our new de-novo assembled genome also showed comparable quality metrics to other coral long-read genomes. Telomeric repeat analysis identified putative chromosomes in our scaffolded assembly, with these repeats at either one, or both ends, of scaffolded contigs. We identified 32,172 protein coding genes in our assembly through use of long-read RNA sequencing (ISO-seq) of additional O. faveolata fragments exposed to a range of abiotic and biotic treatments, and publicly available short-read RNA-seq data. With anthropogenic influences heavily affecting O. faveolata, as well as its increasing incorporation into reef restoration activities, this updated genome resource can be used for population genomics and other 'omics analyses to aid in the conservation of this species., (© 2024.

Introduction: Pooled procurement can be seen as a collaboration initiative of buyers. Such mechanisms have received increased attention during the Covid-19 pandemic to improve access to affordable and quality-assured health commodities. The structural form of pooled procurement mechanisms ranges from a third-party organization that procures on behalf of its buyers to a buyer's owned mechanism in which buyers operate more collaboratively. However, little is known about how these types of pooled procurement mechanisms differ in terms of characteristics, implementation and developmental process. To fill this gap, we compared four pooled procurement mechanisms. Two buyer's owned mechanisms: the Organisation of the Eastern Caribbean States (OECS) and the Pacific Island Countries (PIC). And two third-party mechanisms: the Global Drug Facility (GDF) and the Asthma Drug Facility (ADF)., Methods: For this qualitative study, we used a multiple case-study design. The cases were purposefully selected, based on a most-similar case study design. We used the Pooled Procurement Guidance to collect data on individual cases and compared our findings between the case studies. For our analysis, we drew upon peer-reviewed academic articles, grey literature documents and 9 semi-structured interviews with procurement experts., Results: Buyers within a buyer's owned mechanisms differ in procurement systems, financing structures, product needs and regulatory and legal frameworks. Therefore, buyers within such mechanisms require relative alignment on motivations, goals and operations of the mechanism. Our study showed that buyers' relative homogeneity of characteristics and their perceived urgency of the problems was particularly relevant for achieving that alignment. Third-party organization mechanisms require less alignment and consensus-building between buyers. To participate, buyers need to align with the operations of the third-party organization, instead of other buyers. Elements that were essential for the successful implementation and operation of such mechanisms included the procurement secretariat's ability to create local and global awareness around the problem, to induce political will to act upon the problem, to mobilize sufficient funding and to attract qualified staff., Conclusion: To successfully sustain pooled procurement mechanisms over time, key actors should drive the mechanism through continuous and reflexive work on stakeholder engagement, mobilization of funding and alignment of interests and needs., (© 2023.

Background: Non-communicable diseases (NCDs) are the leading cause of mortality across the Caribbean and similar regions. Structural determinants include a marked increase in the dependency on food imports, and the proliferation of processed foods, including sugar-sweetened beverages (SSBs). We focused on Jamaica as a case study and the health challenge of SSBs, and situated contemporary actions, experiences and policies within their historical context to investigate underlying drivers of commercial determinants of health and attempts to counter them. We asked: how can a historical perspective of the drivers of high level SSB consumption in Jamaica contribute to an enhanced understanding of the context of public health policies aimed at reducing their intake?, Methods: An ethnographic approach with remote data collection included online semi-structured interviews and workshops with 22 local experts and practitioners of health, agriculture and nutrition in Jamaica and attending relevant regional public webinars on SSBs and NCD action in the Caribbean. Our analysis was situated within a review of historical studies of Caribbean food economies with focus on the twentieth century. Jamaican and UK-based researchers collected and ethnographically analysed the data, and discussed findings with the wider transdisciplinary team., Results: We emphasise three key areas in which historical events have shaped contextual factors of SSB consumption. Trade privileged sugar as a cash crop over food production during Jamaica's long colonial history, and trade deregulation since the 1980s through structural adjustment opened markets to transnational companies. These changes increased Jamaican receptiveness to the mass advertisement and marketing of these companies, whilst long-standing power imbalances hampered taxation and regulation in contemporary public health actions. Civil society efforts were important for promoting structural changes to curb overconsumption of SSBs and decentring such entrenched power relations., Conclusion: The contemporary challenge of SSBs in Jamaica is a poignant case study of commercial determinants of health and the important context of global market-driven economies and the involvement of private sector interests in public health policies and governance. Historically contextualising these determinants is paramount to making sense of the sugar ecology in Jamaica today and can help elucidate entrenched power dynamics and their key actors., (© 2023.

Background: The establishment of international collaborative research partnerships in times of infectious disease outbreaks of international importance has been considered an ethical imperative. Frail health research systems in low- and middle-income countries can be an obstacle to achieve the goal of knowledge generation and the search for health equity before, during and after infectious disease outbreaks.Methods: A qualitative case study was conducted to identify the challenges and opportunities facing the Dominican Republic with regards to developing international collaborative research partnerships in the context of the Zika outbreak and its ethical implications. Researchers conducted 34 interviews (n = 30 individual; n = 4 group) with 39 participants (n = 23 males; n = 16 females) representing the government, universities, international donor agencies, non-governmental organisations, community-based organisations and medical societies, in two metropolitan cities.Results: Five international collaborative research projects related to the Zika virus were identified. Major ethical challenges were linked to the governance of health research, training of human resources, the institutionalisation of scientific activity, access to research funds and cultural aspects. Capacity-building was not necessarily a component of some partnership agreements. With few exceptions, local researchers were merely participating in data collection and less on defining the problem. Opportunities for collaborative work included the possibility of participation in international research consortiums through calls for proposals.Conclusions: The Dominican government and research stakeholders can contribute to the international response to the Zika virus through active participation in international collaborative research partnerships; however, public recognition of the need to embrace health research as part of public policy efforts is warranted. A working group led by the government and formed by national and international research stakeholders will be key to identify ways in which the country could respond to the ethical demand of generating new knowledge in times of outbreaks.

Background: Social factors and networks of friends can influence an adolescent's behavior, including academic performance (AP) in school. This study aimed to analyze the relationship between AP and adolescents' social networks in a Caribbean city in Colombia., Methods: A cross-sectional study was carried out with 806 schoolchildren from 12 to 17 years old of both sexes (52.7% girls), selected by multi-stage sampling from schools in the rural and urban areas of the city of Montería, Colombia. The AP was obtained from the school records; the sociodemographic variables included the location of the school (rural or urban), family structure, family functioning (Apgar score), and family affluence scale. Social network variables included social activity, popularity, reciprocity, homophily, friends' academic performance, network size, network density, cluster of friends, and centrality., Results: The AP was inversely associated with the Apgar score in boys. No associations of AP with the school location, family structure, family affluence scale, and age were observed. In social network variables, AP was positively associated with popularity and friends' academic performance in girls and boys, and negatively associated with homophily in boys., Conclusions: AP was associated with social network variables. These results could help implement interventions to improve adolescents' social environment and AP., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Background: Feed restriction occurs frequently during pig growth, either due to economic reasons or stressful environmental conditions. Local breeds are suggested to have better tolerance to periods of feed restriction. However, the mechanisms underlying the response to feed restriction in different breeds is largely unknown. The aims of the present study were (1) to compare the blood transcriptome profile in response to feed restriction and refeeding of two contrasted breeds, Large White (LW), which has been selected for high performance, and Creole (CR), which is adapted to tropical conditions, and (2) to investigate the effect of a moderate feed restriction and refeeding on whole blood transcriptome. Analysis of blood transcriptome allows to study the response to feed restriction and refeeding in a dynamic way. RNAseq was performed on blood samples of growing LW and CR pigs at two time points: after 3 weeks of feed restriction and after 3 weeks of refeeding. The data was compared with samples from control animals offered the same diet on an ad libitum basis throughout the whole experiment., Results: In terms of performance (body weight and feed efficiency), CR pigs were less impacted by feed restriction than LW. The transcriptional response to feed restriction and refeeding between CR and LW was contrasted both in terms of number of DEGs and enriched pathways. CR demonstrated a stronger transcriptional response to feed restriction whereas LW had a stronger response to refeeding. Differences in the transcriptional response to feed restriction between CR and LW were related to cell stress response (Aldosterone Signalling, Protein ubiquitination, Unfolded Protein Signalling) whereas after refeeding, differences were linked to thermogenesis, metabolic pathways and cell proliferation (p38 MAPK, ERK/MAPK pathway). In both breeds, transcriptional changes related to the immune response were found after restriction and refeeding., Conclusions: Altogether, the present study indicates that blood transcriptomics can be a useful tool to study differential genetic response to feed restriction in a dynamic way. The results indicate a differential response of blood gene expression to feed restriction and refeeding between breeds, affecting biological pathways that are in accordance with performance and thermoregulatory results., (© 2023.

Background: Martinique shares with the other Caribbean countries specific public health issues, particularly in the diagnostic and therapeutic management of cancer patients. Mutualization of human and material resources by promoting cooperation is the most appropriate response to the challenges of the health systems of the Caribbean territories. Through the French PRPH-3 program, we propose to set up a collaborative digital platform adapted to the specificities of the Caribbean to strengthen professional links and skills in oncofertility and oncosexology and reduce inequalities in access to reproductive and sexual health care for cancer patients., Methods: Within the context of this program, we have developed of an open-source platform based on a Learning Content Management System (LCMS), with an operating system developed by UNFM for low speed internet. LO libraries have been created and interaction between trainers and learners were done in asynchronous mode. This training management platform is based on: a TCC learning system (Training, Coaching, Communities); a web-hosting with pedagogical engineering appropriate to low bandwidth; a reporting system and a responsibility for processing., Results: We have carried out a flexible, multilingual and accessible digital learning strategy functionality called e-MCPPO according to low-speed internet ecosystem. In close connection with the e-learning strategy we conceived (i) a multidisciplinary team; (ii) an appropriate training program for expert health professionals and (iii) a responsive design., Discussion and Conclusion: This low-speed web-based infrastructure allows communities of experts to cooperate in creating, validating, publishing and managing academic learning content. The self-learning modules provide the digital layer for each learner to extend their skills. Learners, as well as trainers, would gradually take ownership of this platform and encourage its promotion. Innovation in this context is both technological (low-speed Internet broadcasting, free interactive software) and organizational (moderating educational resources). This collaborative digital platform is unique in its form and content. This challenge could contribute to the digital transformation of the Caribbean ecosystem for capacity building in this specifics topics., (© 2023. The Author(s).)

Background: Worldwide, a significant proportion of head and neck cancers is attributed to the Human papillomavirus (HPV). It is imperative that we acquire a solid understanding of the natural history of this virus in head and neck squamous cell carcinoma (HNSCC) development. Our objective was to investigate the role of sexual behaviour in the occurrence of HNSCC in the French West Indies. Additionally, we evaluated the association of high risk of HPV (Hr-HPV) with sexual behaviour in risk of cancer., Methods: We conducted a population-based case-control study (145 cases and 405 controls). We used logistic regression models to estimate adjusted odds-ratios (OR), and their 95% confidence intervals (CI)., Results: Compared to persons who never practiced oral sex, those who practiced at least occasionally had a lower HNSCC risk. First sexual intercourse after the age of 18 year was associated with a 50% reduction of HNSCC risk, compared to those who began before 15 years. HNSCC risk was significantly reduced by 60% among persons who used condoms at least occasionally. The associations for ever condom use and oral sex were accentuated following the adjustment for high-risk HPV (Hr-HPV). Oral Hr-HPV was associated with several sexual behaviour variables among HNSCC cases. However, none of these variables were significantly associated with oral HPV infections in the population controls., Conclusion: First intercourse after 18 years, short time interval since last intercourse and ever condom use were inversely associated with HNSCC independently of oral Hr-HPV infection. Sources of transmission other than sexual contact and the interaction between HPV and HIV could also play a role in HNSCC etiology., (© 2023. The Author(s).)

Background: Diabetic retinopathy is a sight-threatening ocular complication of diabetes. Screening is an effective way to reduce severe complications, but screening attendance rates are often low, particularly for newcomers and immigrants to Canada and people from cultural and linguistic minority groups. Building on previous work, in partnership with patient and health system stakeholders, we co-developed a linguistically and culturally tailored tele-retinopathy screening intervention for people living with diabetes who recently immigrated to Canada from either China or African-Caribbean countries., Methods: Following an environmental scan of diabetes eye care pathways in Ottawa, we conducted co-development workshops using a nominal group technique to create and prioritize personas of individuals requiring screening and identify barriers to screening that each persona may face. Next, we used the Theoretical Domains Framework to categorize the barriers/enablers and then mapped these categories to potential evidence-informed behaviour change techniques. Finally with these techniques in mind, participants prioritized strategies and channels of delivery, developed intervention content, and clarified actions required by different actors to overcome anticipated intervention delivery barriers., Results: We carried out iterative co-development workshops with Mandarin and French-speaking individuals living with diabetes (i.e., patients in the community) who immigrated to Canada from China and African-Caribbean countries (n = 13), patient partners (n = 7), and health system partners (n = 6) recruited from community health centres in Ottawa. Patients in the community co-development workshops were conducted in Mandarin or French. Together, we prioritized five barriers to attending diabetic retinopathy screening: language (TDF Domains: skills, social influences), retinopathy familiarity (knowledge, beliefs about consequences), physician barriers regarding communication for screening (social influences), lack of publicity about screening (knowledge, environmental context and resources), and fitting screening around other activities (environmental context and resources). The resulting intervention included the following behaviour change techniques to address prioritized local barriers: information about health consequence, providing instructions on how to attend screening, prompts/cues, adding objects to the environment, social support, and restructuring the social environment. Operationalized delivery channels incorporated language support, pre-booking screening and sending reminders, social support via social media and community champions, and providing using flyers and videos as delivery channels., Conclusion: Working with intervention users and stakeholders, we co-developed a culturally and linguistically relevant tele-retinopathy intervention to address barriers to attending diabetic retinopathy screening and increase uptake among two under-served groups., (© 2023.

Biomedical advances in healthcare and antiretroviral treatment or therapy (ART) have transformed HIV/AIDS from a death sentence to a manageable chronic disease. Studies demonstrate that people living with HIV who adhere to antiretroviral therapy can achieve viral suppression or undetectability, which is fundamental for optimizing health outcomes, decreasing HIV-related mortality and morbidity, and preventing HIV transmission. African, Caribbean, and Black (ACB) communities in Canada remain structurally disadvantaged and bear a disproportionate burden of HIV despite biomedical advancements in HIV treatment and prevention. This institutional ethnography orients to the concept of 'structural violence' to illuminate how inequities shape the daily experiences of ACB people living with HIV across the HIV care cascade. We conducted textual analysis and in-depth interviews with ACB people living with HIV (n = 20) and health professionals including healthcare providers, social workers, frontline workers, and health policy actors (n = 15). Study findings produce a cumulative understanding that biomedical HIV discourses and practices ignore structural violence embedded in Canada's social fabric, including legislation, policies and institutional practices that produce inequities and shape the social world of Black communities. Findings show that inequities in structural and social determinants of health such as food insecurity, financial and housing instability, homelessness, precarious immigration status, stigma, racial discrimination, anti-Black racism, criminalization of HIV non-disclosure, health systems barriers and privacy concerns intersect to constrain engagement and retention in HIV healthcare and ART adherence, contributing to the uncertainty of achieving and maintaining undetectability and violating their right to health. Biomedical discourses and practices, and inequities reduce Black people to a stigmatized, pathologized, and impoverished detectable viral underclass. Black people perceived as nonadherent to ART and maintain detectable viral loads are considered "bad" patients while privileged individuals who achieve undetectability are considered "good" patients. An effective response to ending HIV/AIDS requires implementing policies and institutional practices that address inequities in structural and social determinants of health among ACB people., (© 2023.

Objective: To assess awareness levels and knowledge of colorectal cancer (CRC) and CRC screening among an Indigenous Caribbean community., Methods: A community-based participatory research project was developed to perform a needs assessment of cancer prevention and education in an Indigenous non-metropolitan community in Dominica. Purposive sampling occurred at a local health clinic. Data was collected from 58 eligible patients via a 57-item structured interview. Descriptive statistics were calculated, and demographic correlates of CRC knowledge and awareness were assessed using chi-square and Fisher Exact tests., Results: Of 58 participants, 72.4% identified as Indigenous, and 36.5% had heard of CRC. Most respondents (96.1%) believed CRC screening to be "important," yet only 3.0% of those who were age eligible had received screening in the prior 10 years, and 12.5% knew how to get screened. More respondents with incomes over $5,000 ECD had heard of CRC (72.2%) compared to those who had not (21.7%), and those who were unsure (16.7%, p < 0.01). Among those with a family cancer history, 14.3% knew how to get tested for CRC, 60.0% did not, and 25.0% were unsure (p < 0.03)., Conclusion: Despite limited familiarity with CRC screening, participants broadly believed CRC screening to be important. Health education research is needed to develop patient-centered, culturally appropriate materials about CRC screening and prevention. Future work facilitating productive community partnerships and incorporating prevailing community traditions may align cancer prevention and education initiatives with community priorities., (© 2023.

Introduction: The epidemiology and clinical presentation of systemic juvenile idiopathic arthritis (sJIA) in the Afro-Caribbean population is not well described., Methods: Retrospective study conducted between January 2000 and January 2022 in the French Overseas Departments of America. Clinical data were obtained from multiple sources: computerized hospital archives, registries of referring pediatricians, and the French National Registry for rare diseases. The disease studied was sJIA defined according to international criteria., Results: Twenty-five patients were identified. Mean age at diagnosis was 7.5 years (range: 1.2-14.9 years) and mean duration of follow-up was 5.2 years (range: 0.5-16 years). All patients had joint involvement at diagnosis with 68% presenting inflammatory arthritis and 32% inflammatory joint pain. Sixteen percent had coronary involvement at onset. More than half (52%) suffered from macrophage activation syndrome (MAS) during childhood (32% at onset). The mean number of flares in childhood was 2 (Range: 1-5). Sixty-eight percent of patients had disease control during childhood without biotherapy. The most frequent second line treatment was anakinra (7/8). There was no difference in clinical or biological severity according to gender. The median duration of treatment during childhood was 5 months (range: 2-144) and 72% had a cumulative treatment duration of less than one year., Conclusion: These patients of Afro-Caribbean origin suffering from sJIA showed some specificities, such as a higher rate of MAS and coronary involvement at onset. The incidence per year was stable over a 20-year period. Overall outcomes during childhood were similar to western countries., (© 2022. The Author(s).)

Background: The African, Caribbean, and Black (ACB) population of Ontario, Canada is comprised of individuals with diverse ethnic, cultural and linguistic backgrounds and experiences; some of whom have resided in Canada for many generations, and others who have migrated in recent decades. Even though the ACB population represents less than 3.5% of the Canadian population, this group accounts for 21.7% of all new HIV infections. It is well-documented that ACB populations, compared to the general population, experience multi-level barriers to accessing appropriate and responsive HIV services. In this paper, we present qualitative findings on the ACB population's experiences with HIV-testing, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) and obtain their perspectives on how to improve access., Methods: We conducted twelve Focus Group Discussions (FGDs), within a two-day World Café event and used socio-ecological framework and community-based participatory research (CBPR) approaches to guide this work. We meaningfully engaged ACB community members in discussions to identify barriers and facilitators to HIV testing, PEP and PrEP and how these may be addressed. The FGDs were transcribed verbatim and thematic analysis guided data interpretation. Credibility of data was established through data validation strategies such as external audit and peer-debriefing., Results: Our analyses revealed multi-level barriers that explain why ACB community members do not access HIV testing, PEP and PrEP. Fear, health beliefs, stigma and lack of information, were among the most frequently cited individual- and community-level barriers to care. Health system barriers included lack of provider awareness, issues related to cultural sensitivity and confidentiality, cost, and racism in the health care system. Participants identified multi-level strategies to address the HIV needs including community-based educational, health system and innovative inter-sectoral strategies., Conclusion: CBPR, co-led by community members, is an important strategy for identifying the multi-level individual, interpersonal, community, institutional and structural factors that increase HIV vulnerability in ACB communities, notably anti-Black systemic racism. Study findings suggest the need for targeted community-based strategies and strategies aimed at reducing health system barriers to testing and care., (© 2022. The Author(s).)

Background: Early introduction of liquid/solid food before 6 months of age is one of the major barriers to exclusive breastfeeding. Our objective was to analyze the evolution of infant feeding practices for infants under 6 months of age in Latin American and Caribbean countries in the decades of 1990, 2000 and 2010., Method: Cross-sectional time series study with data from Demographic and Health Surveys carried out between 1990 and 2017 in six Latin America and Caribbean countries: Bolivia (1994 to 2008), Colombia (1995 to 2010), Dominican Republic (1996 to 2013), Guatemala (1995 to 2015), Haiti (1994/1995 to 2016/2017), Peru (1996 to 2018). Pooled sample comprised of 22,545 infants under the age of 6 months. Surveys were grouped in three decades: 1990s for surveys from 1990 to 1999, 2000s for surveys from 2000 to 2009, and 2010s for surveys from 2010 to 2017. Exclusive breastfeeding (EBF), predominant breastfeeding (PBF), mixed breastfeeding (mixed BF), supplemented breastfeeding (supplemented BF) and non-breastfeeding (non-BF), and individual foods (water, liquids, milk, infant formula, semi-solid/solid) were analyzed. Prevalence of breastfeeding and food indicators were calculated in pooled sample, according to the infant monthly age groups, decade of survey and residence area(rural/urban)., Results: Between 1990s and 2010s, there was an increase in the exclusive breastfeeding prevalence (1990s = 38.1%, 2010s = 46.6%) and a reduction in the PBF prevalence (1990s = 51.7%, 2010 s = 43.1%). There was a decrease in the liquids (1990s = 40.7%, 2010s = 15.8%) and milk prevalence (1990s = 20.4%, 2010s = 8.3%) and an increase in water (1990s = 32.3%, 2010s = 37.6%), and infant formula (1990s = 16.6%, 2010s = 25.5%) prevalence. All breastfeeding indicators, except exclusive breastfeeding, progressively increased according to the monthly age group in three decades, and EBF prevalence sharply decreased from 2 to 3 months of age in all decades. Exclusive breastfeeding prevalence was higher in rural area in the three decades (1990s rural  = 43.8%, 1990s urban  = 32.4%, 2010s rural  = 51.1%, 2010s urban  = 42.4%) and infant formula prevalence was higher in urban area (1990s rural  = 8.6%, 1990s urban  = 24.6%, 2010s rural  = 15.9%, 2010s urban  = 34.1%)., Conclusions: In the last three decades, in all age groups, there was an increase in exclusive breastfeeding prevalence, as well as a significant reduction in liquids and milk. In the rural area, EBF prevalence remains higher than in urban. Increased water and infant formula feeding are the main barriers to achieving the Global Nutrition Target 2025 for exclusive breastfeeding., (© 2022. The Author(s).)

Background: Waterborne diarrhea diseases are among the leading causes of morbidity and mortality globally. These diseases can be mitigated by implementing various interventions. We reviewed the literature to identify available interventions to mitigate the risk of waterborne diarrheal diseases., Methods: We conducted a systematic database review of CINAHL (Cumulative Index to Nursing and Allied Health Literature), PubMed, Web of Science Core Collection, Cochrane library, Scopus, African Index Medicus (AIM), and LILACS (Latin American and Caribbean Health Sciences Literature). Our search was limited to articles published between 2009 and 2020. We conducted the review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement checklist. The identified studies were qualitatively synthesized., Results: Our initial search returned 28 773 articles of which 56 studies met the inclusion criteria. The included studies reported interventions, including vaccines for rotavirus disease (monovalent, pentavalent, and Lanzhou lamb vaccine); enhanced water filtration for preventing cryptosporidiosis, Vi polysaccharide for typhoid; cholera 2-dose vaccines, water supply, water treatment and safe storage, household disinfection, and hygiene promotion for controlling cholera outbreaks., Conclusion: We retrieved few studies on interventions against waterborne diarrheal diseases in low-income countries. Interventions must be specific to each type of waterborne diarrheal disease to be effective. Stakeholders must ensure collaboration in providing and implementing multiple interventions for the best outcomes., Systematic Review Registration: PROSPERO CRD42020190411 ., (© 2022. The Author(s).)
