Gender Differences in Trends in Incidence and Mortality of Acute Myocardial Infarction in the Small Island Developing State of Barbados.

Objective To determine trends, identify predictors of acute myocardial infarction (AMI) incidence and mortality, and explore performance metrics for AMI care in Barbados. Methods Data on all cases diagnosed with AMI were collected by the Barbados National Registry for Non-Communicable Diseases (BNR) from the island's only tertiary hospital, the Queen Elizabeth Hospital, and the National Vital Registration Department. Participants who survived hospital admission were then followed up at 28 days and one year post event via telephone survey and retrieval of death certificates. Age-standardized incidence and mortality rates were calculated. Determinants of mortality at 28 days were examined in multivariable logistic regression models. Median and interquartile ranges (IQR) were calculated for performance metrics (e.g., time from pain onset to reperfusion). Results In a 10-year period between 2010 and 2019, 4,065 cases of myocardial infarction were recorded. The median age of the sample was 73 years (IQR: 61,83), and approximately half (47%) were female. Over a 10-year period, standardized incidence increased in women on average yearly by three per 100,000 (95% CI: 1 to 6; p=0.02), while in men, the average increase per year was six per 100,000 (95% CI: 4 to 8; p<0.001). There was no increase in 28-day mortality in women; mortality in men increased each year by 2.5 per 100,000 (95% CI: 0.4 to 4.5; p=0.02). The time from arrival at the hospital to the ECG was 44 minutes IQR (20,113). Conclusion AMI incidence and mortality are increasing in Barbados, and men have a higher velocity of mortality rate increase than women, which contradicts global data.

Faith-based leaders' perceptions on the implementation of programs to promote healthy lifestyles in churches in Barbados-a mixed-methods analysis.

Background: There is a high burden of chronic diseases such as hypertension and diabetes in small island developing states (SIDS). SIDS governments have committed to a range of public health, healthcare, and fiscal measures to reduce this burden including community-based health education in collaboration with civil society organizations. We sought to explore perceived acceptability, appropriateness, and feasibility of implementing self-management health programs in 20 faith-based organizations in the small island developing state of Barbados. Methods: This was a concurrent mixed methods study - a quantitative online survey and a qualitative inquiry using semi-structured interviews. Acceptability, appropriateness and feasibility of the intervention were assessed using the following quantitative assessment tools: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM). Thirteen in-depth interviews were conducted virtually, recorded and transcribed verbatim. Transcripts were analyzed using thematic analysis based on deductive codes from Proctor's implementation outcomes definitions. Results: From the 52 respondents of the survey, the median and interquartile ranges for the AIM, IAM and FIM scales were 16 (15-20), 16 (16-20) and 16 (15-17) (out of 20), respectively. We found high levels of acceptability, 82% (95% CI (69%, 95%)) of leaders indicating that health programs in churches met with their approval; and high levels of appropriateness-90% (95% CI (80%, 100%)) indicating health programs in churches were "fitting" and "a good match". Feasibility scores were lower, with 60% (95% CI (44%, 76%)) indicating that health programs in churches would be easy to use. In interviews, leaders expressed acceptance of healthy lifestyle programs in churches and described their appropriateness through alignment with church doctrines stating, "the body is the temple of God". They felt that economic impacts from COVID-19 were likely to be a barrier to the success of programs. Leaders expressed the need for support from healthcare providers who are sensitive and respectful of church culture. Conclusion: We found that health-based programs in churches align well with church doctrines, but the success of these programs will depend on establishing trust through the engagement of church-based champions, tailoring programming to include a biblical perspective and engaging entire households.

Acute splenic sequestration in HbSS: observations from the Jamaican birth cohort.

OBJECTIVE: To document the prevalence, clinical features, haematology and outcome of acute splenic sequestration (ASS) in homozygous sickle cell disease (HbSS). STUDY DESIGN: A cohort study from birth. SETTING: The Medical Research Council Laboratories at the University of the West Indies, Kingston, Jamaica. PATIENTS: 311 cases of HbSS detected during the screening of 100 000 deliveries at the main government maternity hospital between 1973 and 1981. INTERVENTIONS: Long-term follow-up and free patient care focusing on ASS. MAIN OUTCOME MEASURE: Acute splenic sequestration. RESULTS: There were 183 episodes of ASS in 105 patients representing 35% of the cohort. The median age for first event was 1.07 years. During ASS, median values for haemoglobin fell by 32 g/dL, reticulocytes increased by 8% and total nucleated cells increased by 10.5%. ASS recurred in 47 (45%) patients. Conservative therapy in 133 episodes of 85 patients was associated with five deaths and splenectomy in 20 patients with 50 episodes had no deaths. Symptoms were generally non-specific but acute chest syndrome occurred in 17, and blood cultures revealed coagulase negative staphylococci in 5. The ASS case fatality rate was 3.6% and may be higher if autopsy evidence of ASS is included. There was no seasonal pattern but higher levels of fetal haemoglobin predicted patients less prone to ASS and its later occurrence. CONCLUSIONS: ASS remains an important cause of morbidity and mortality in HbSS in developing societies. ASS appears to be a non-specific response to many possible risk factors including coagulase negative staphylococci.

Neighbourhood Walkability and Its Influence on Physical Activity and Cardiometabolic Disease: A Cross-Sectional Study in a Caribbean Small Island Developing State.

Introduction Cities and neighborhoods may provide opportunities for population-level environmental interventions to reduce physical inactivity and cardiometabolic risk. In this study, we describe the association between neighborhood walkability, physical activity (PA), and cardiometabolic outcomes, by linking data from a nationally representative survey of adults (25 years and older) collected in 2012-2013 with spatial data on built environment features in Barbados. Methods We estimated a walkability index for 45 neighborhoods using objectively measured built environment features (residential density, street connectivity, and land use mix). We used the Recent Physical Activity Questionnaire to capture time spent in outdoor walking, active commuting, moderate-to-vigorous PA (MVPA), and total PA. Our primary cardiometabolic outcome was a predicted 10-year cardiovascular risk (CVD) score, estimated using the American College of Cardiology/American Heart Association pooled cohort equation. Our secondary cardiometabolic outcomes were hypertension and diabetes. We explored the effect of neighborhood walkability on PA and cardiometabolic outcomes using several multivariable regression models (tobit and linear and logistic multi-level mixed effects), with the model choice depending on the structure of the outcome.  Results The average time spent walking weekly for any purpose among participants was 75 minutes/week, time spent on active commuting was 15 minutes/week, and MVPA was 221 minutes/week. We estimated that the average 10-year CVD risk in the study population was 11.7% (95%CI 10.9-12.5). Our confounder-adjusted analyses showed positive linear relationships between neighborhood walkability and each PA outcome (p<0.05 in all cases), and a negative relationship between walkability and predicted 10-year CVD risk (p<0.001). Conclusion In our setting, adults residing in higher walkability neighborhoods spent more time engaged in PA, had a lower predicted 10-year CVD risk, and were less likely to have diabetes. Urban planners may consider shorter-term interventions, such as those on a microscale, which may provide additional ways to increase activity in a mostly fixed macroscale environment.

Experiences with SARS-CoV-2 (Covid-19) in Trinidad and Tobago, a small island developing state: realities and opportunities.

The COVID-19 pandemic has exerted significant global challenges that are expressed in a variety of socio-politico-economic scenarios, depending upon individual countries' preparedness and resilience. The impact COVID-19 in Small Island Developing States (SIDS), most of which are categorized as Lower and Middle-Income Countries, has been pronounced. Furthermore, many of these SIDS possess specific vulnerabilities to global threats. This paper contextualizes the experience of Trinidad and Tobago from some perspectives of geoeconomics, healthcare, and international relations. In many ways, the experience is similar to that of other SIDS with the inherent nuances of a post-colonial world. Trinidad and Tobago was ranked number one by the Oxford University COVID-19 Government Response Tracker (OxCGRT) "Lockdown rollback checklist: Do countries meet WHO recommendations for rolling back lockdown?". Despite the significant political support to combat the disease, by the end of 2022, the country had recorded over four thousand deaths and just over 50% of the population is vaccinated. This paper seeks to discuss the successes and challenges faced by this twin island state.

The Burden of Pediatric Visual Impairment and Ocular Diagnoses in Barbados.

Visual impairment (VI) negatively affects a child's quality of life. The prevalence of VI in the Caribbean is nearly three times higher than in the United States, but the causes remain uncertain. This study leverages Barbados' unique eye care system to survey the eye diseases and VI prevalence in Barbadian children. Medical records of all patients aged <19 years who received ophthalmic care in Barbados' two public eye care centers between January and December 2019 were reviewed, capturing the entirety of public pediatric eye care within the study period. Age at the first visit to the clinic and at the final visit in 2019, sex, best-corrected visual acuity (BCVA), past medical history, and clinical diagnoses were extracted and analyzed. VI was defined as a BCVA of 6/12 or worse in the better-seeing eye. There were 3278 patient records with a mean age at the first visit of 7.8 ± 3.9 years. There were 80 (2.4%) children with VI, 62.5% of which were attributed to amblyopia. A total of 94% of VI was preventable or treatable. The most common diagnoses were refractive error (87.5%), strabismus (27.5%), and allergic eye disease (20.0%). Amblyopia is the major cause of pediatric VI in Barbados and is largely avoidable.

Multimorbidity and social determinants of health in the US prior to the COVID-19 pandemic and implications for health outcomes: a cross-sectional analysis based on NHANES 2017-2018.

Multimorbidity increases the risk of all-cause mortality, and along with age, is an independent risk factor for severe disease and mortality from COVID-19. Inequities in the social determinants of health contributed to increased mortality from COVID-19 among disadvantaged populations. This study aimed to evaluate the prevalence of multimorbid conditions and associations with the social determinants of health in the US prior to the pandemic.Methods Data from the 2017-18 cycle of NHANES were used to determine the prevalence of 13 chronic conditions, and the prevalence of having 0, 1, or 2 or more of those conditions, among the US adult population aged ≥ 20 years. Multimorbidity was defined as having 2 or more of these conditions. Data were stratified according to demographic, socioeconomic and indicators of health access, and analyses including logistic regression, performed to determine the factors associated with multimorbidity.Results The prevalence of multimorbidity was 58.4% (95% CI 55.2 to 61.7). Multimorbidity was strongly associated with age and was highly prevalent among those aged 20-29 years at 22.2% (95% CI 16.9 to 27.6) and continued to increase with older age. The prevalence of multimorbidity was highest in those defined as Other or multiple races (66.9%), followed in decreasing frequency by rates among non-Hispanic Whites (61.2%), non-Hispanic Blacks (57.4%), Hispanic (52.0%) and Asian (41.3%) groups.Logistic regression showed a statistically significant relationship between multimorbidity and age, as expected. Asian race was associated with a reduced likelihood of 2 or more chronic conditions (OR 0.4; 95% CI 0.35 to 0.57; P < 0.0001). Socioeconomic factors were related to multimorbidity. Being above the poverty level (OR 0.64; 95% CI 0.46 to 0.91, p = 0.013); and a lack of regular access to health care (OR 0.61 (95% CI 0.42 to 0.88, p = 0.008) were both associated with a reduced likelihood of multimorbidity. Furthermore, there was a borderline association between not having health insurance and reduced likelihood of multimorbidity (OR 0.63; 95% CI 0.40 to 1.0; p = 0.053).Conclusions There are high levels of multimorbidity in the US adult population, evident from young adulthood and increasing with age. Cardiometabolic causes of multimorbidity were highly prevalent, especially obesity, hyperlipidemia, hypertension, and diabetes; conditions subsequently found to be associated with severe disease and death from COVID-19. A lack of access to care was paradoxically associated with reduced likelihood of comorbidity, likely linked to underdiagnosis of chronic conditions. Obesity, poverty, and lack of access to healthcare are factors related to multimorbidity and were also relevant to the health impact of the COVID-19 pandemic, that must be addressed through comprehensive social and public policy measures. More research is needed on the etiology and determinants of multimorbidity, on those affected, patterns of co-morbidity, and implications for individual health and impact on health systems and society to promote optimal outcomes. Comprehensive public health policies are needed to tackle multimorbidity and reduce disparities in the social determinants of health, as well as to provide universal access to healthcare.

The rising burden of non-communicable diseases in the Americas and the impact of population aging: a secondary analysis of available data.

Background: Public health progress in the Americas has reduced the burden of many infectious diseases, helping more people live longer lives. At the same time, the burden of non-communicable diseases (NCDs) is increasing. NCD prevention rightly focuses on lifestyle risk factors, social, and economic determinants of health. There is less published information on the importance of population growth and aging to the regional NCD burden. Methods: For 33 countries in the Americas, we used United Nations population data to describe rates of population growth and aging over two generations (1980-2060). We used World Health Organization estimates of mortality and disability (disability-adjusted life years, DALYs) to describe changes in the NCD burden between 2000 and 2019. After combining these data resources, we decomposed the change in the number of deaths and DALYs to estimate the percentage change due to population growth, due to population aging, and due to epidemiological advances, measured by changing mortality and DALY rates. In a supplement, we provide a summary briefing for each country. Findings: In 1980, the proportion of the regional population aged 70 and older was 4.6%. It rose to 7.8% by 2020 and is predicted to rise to 17.4% by 2060. Across the Americas, DALY rate reductions would have decreased the number of DALYs by 18% between 2000 and 2019 but was offset by a 28% increase due to population aging and a 22% increase due to population growth. Although the region enjoyed widespread reductions in rates of disability, these improvements have not been sufficiently large to offset the pressures of population growth and population aging. Interpretation: The region of the Americas is aging and the pace of this aging is predicted to increase. The demographic realities of population growth and population aging should be factored into healthcare planning, to understand their implications for the future NCD burden, the health system needs, and the readiness of governments and communities to respond to those needs. Funding: This work was funded in part by the Pan American Health Organization, Department of Noncommunicable Diseases and Mental Health.

Active travel and paratransit use in African cities: Mixed-method systematic review and meta-ethnography.

Active travel, as a key form of physical activity, can help offset noncommunicable diseases as rapidly urbanising countries undergo epidemiological transition. In Africa a human mobility transition is underway as cities sprawl and motorization rises and preserving active travel modes (walking, cycling and public transport) is important for public health. Across the continent, public transport is dominated by paratransit, privately owned informal modes serving the general public. We reviewed the literature on active travel and paratransit in African cities, published from January 2008 to January 2019. We included 19 quantitative, 14 mixed-method and 8 qualitative studies (n = 41), narratively synthesizing the quantitative data and meta-ethnographically analysing the qualitative data. Integrated findings showed that walking was high, cycling was low and paratransit was a critical mobility option for poor peripheral residents facing long livelihood-generation journeys. As an indigenous solution to dysfunctional mobility systems shaped by colonial and apartheid legacies it was an effective connector, penetrating areas unserved by formal public transport and helping break cycles of poverty. From a public health perspective, it preserved active travel by reducing mode-shifting to private vehicles. Yet many city authorities viewed it as rogue, out of keeping with the 'ideal modern city', adopting official anti-paratransit stances without necessarily considering the contribution of active travel to public health. The studies varied in quality and showed uneven geographic representation, with data from Central and Northern Africa especially sparse; notably, there was a high prevalence of non-local authors and out-of-country funding. Nevertheless, drawing together a rich cross-disciplinary set of studies spanning over a decade, the review expands the literature at the intersection of transport and health with its novel focus on paratransit as a key active travel mode in African cities. Further innovative research could improve paratransit's legibility for policymakers and practitioners, fostering its inclusion in integrated transport plans.

Understanding the relationship between built environment features and physical activity in the Caribbean: A scoping review.

Background: Transforming the urban infrastructure to become safe, inclusive and sustainable remains a challenge in most developing settings. The Caribbean has high burdens of physical inactivity and non-communicable diseases. Therefore, understanding the role of the built environment (BE) in modifying individual activity is important for informing the design of community interventions to improve levels of physical activity (PA). Anecdotally, there is limited evidence on the BE in the Caribbean, however evidence from other Small Island Developing States (SIDS) and from Latin America (LA) may offer useful information given their similar urbanization profiles and shared geo-collaborative histories. Objective: Our review identifies and characterizes individual features of the BE and examines their relationships with PA outcomes. Methods: We systematically searched a range of multi-discipline research databases, including studies from SIDS and LA that objectively measured BE features as an exposure and PA as an outcome between 2010 and 2021. Grey literature was not considered for this review. We characterized BE measures into 9 neighbourhood design domains using the Walkability for Health framework, and mapped gaps in the published evidence. We performed a narrative summary of BE-PA relationships, focusing on association strength and direction of effect. Results: Fifty-one studies from published scientific literature in Brazil, Colombia, Mexico, Chile, and Singapore were included that described 306 BE-PA relationships. The BE was mostly characterized by number of and proximity to spaces for social interaction, green spaces, increasing housing density or street connectivity, and mixed residential and commercial land use. BE-PA relationships, although inconsistent, largely promoted PA. Conclusion: Although the review is suggestive of the benefits of the benefits of BE interventions for promoting active commuting and leisurely PA, translational research is needed to understand whether results can be successfully adapted for SIDS, which often have an urban structure defined by a single urban centre with connections to outlying communities.

Inhaled bronchodilators for acute chest syndrome in people with sickle cell disease.

BACKGROUND: Bronchodilators are used to treat bronchial hyper-responsiveness in asthma. Bronchial hyper-responsiveness may be a component of acute chest syndrome in people with sickle cell disease. Therefore, bronchodilators may be useful in the treatment of acute chest syndrome. This is an update of a previously published Cochrane Review. OBJECTIVES: The aim of the review is to determine whether the use of inhaled, short-acting bronchodilators for acute chest syndrome reduces morbidity and mortality in people with sickle cell disease and to assess whether this treatment causes adverse effects. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. Additional searches were carried out on MEDLINE (1966 to 2004) and Embase (1981 to 2004) and ongoing trial registries (28 September 2022). Date of the most recent search of the Group's Haemoglobinopathies Trials Register: 25 July 2022. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials. Trials using quasi-randomisation methods will be included in future updates of this review if there is sufficient evidence that the treatment and control groups are similar at baseline. DATA COLLECTION AND ANALYSIS: We found no trials investigating the use of bronchodilators for acute chest syndrome in people with sickle cell disease. MAIN RESULTS: We found no trials investigating the use of bronchodilators for acute chest syndrome in people with sickle cell disease. AUTHORS' CONCLUSIONS: If bronchial hyper-responsiveness is an important component of some episodes of acute chest syndrome in people with sickle cell disease, the use of inhaled bronchodilators may be indicated. There is need for a well-designed, adequately-powered randomised controlled trial to assess the benefits and risks of the addition of inhaled bronchodilators to established therapies for acute chest syndrome in people with sickle cell disease.

Spleen size in homozygous sickle cell disease: trends in a birth cohort using ultrasound.

OBJECTIVES: To provide ultrasound baselines for spleen length in homozygous sickle cell disease (HbSS) and in normal controls with a HbAA genotype. METHODS: The Jamaican cohort study identified 311 babies with HbSS and 246 matched HbAA controls during the screening of 100,000 consecutive deliveries in Kingston, Jamaica from 1973 to 1981. Ultrasonography commenced in 1988 when the youngest patients were aged 6 years at which time deaths, emigrations and default had reduced the numbers to 206 HbSS and 89 controls. It continued annually until 2000. RESULTS: The spleen was visualized in all HbAA controls but in only 1103/2138 (52%) scans in HbSS. Where available, mean splenic lengths were significantly lower in HbSS (77-103 mm in males, 70-83 mm in females) compared to normal controls (89-101 mm in males, 86-95 mm in females). Assessed by statistical modelling after adjusting for body height, the splenic ratio (splenic length/body height) declined over the age range 12-20 years in HbSS, consistent with progressive splenic fibrosis. Genetic factors known to inhibit sickling, α thalassemia and fetal hemoglobin level (HbF) significantly reduced the decline in splenic ratio. Clinical splenomegaly was an insensitive measure of splenic enlargement as only 50% of patients aged 18 years and above with spleens measuring ≥150 mm on ultrasonography had palpable spleens. CONCLUSIONS: An age-related decline in splenic length occurred in HbSS and occurred more slowly with genetic factors known to inhibit sickling. The standards provided may be of value in assessing minor degrees of subclinical acute splenic sequestration. ADVANCES IN KNOWLEDGE: These are the first standards available for splenic length in HbSS. They may be useful in detecting red cell sequestration, not apparent from clinical splenomegaly and also provide a model for identifying factors inhibiting vaso-occlusion.

Children and the coronavirus disease 2019 pandemic: a Caribbean perspective.

This study aims to assess coronavirus disease 2019 (COVID-19) surveillance methods, health resources, vaccination coverage and income stratification and quantify burdens of disease and death in children and adolescents in the Caribbean. The investigation was a descriptive, cross-sectional study that included 15 Caribbean countries/territories and utilized surveys and secondary data sources. Quarantine and isolation measures were robust and surveillance strategies were similar. Pediatric specialists were available across the region, but few had designated pediatric hospitals or high-dependency units. There were more cases in children on islands with larger populations. Compared to high-income countries/territories, upper and lower middle-income countries/territories had higher disease burdens, fewer doctors and nurses per 1 000 population, lower bed capacities, and lower vaccination coverage. Child and adolescent cases ranged from 0.60% to 16.9%, compared with a global case rate of 20.2% in 2021. By August 2021 there were 33 deaths among children from Haiti, Jamaica, Trinidad and Tobago, and Barbados. The respective case fatality rates for 0-9-year-olds and 10-19-year-olds were 2.80 and 0.70 in Haiti, 0.10 and 0.20 in Jamaica, and 0.00 and 0.14 in Trinidad, compared with 0.17 and 0.1 globally. Overall COVID-19 incidence and mortality in children were consistent with global estimates. Limited resources have been offset by availability of pediatricians across the region, and minimally direct effects on children. Prioritization of admission of specific at-risk groups, training of first responders and vaccination campaigns targeting pregnant women and vulnerable children and adolescents could benefit countries with low vaccine coverage rates and limited resources.

El presente estudio tiene como objetivo evaluar los métodos de vigilancia, los recursos de salud, y la cobertura de vacunación y la estratificación de los ingresos, así como cuantificar las cargas de enfermedad y muerte de la enfermedad por coronavirus del 2019 (COVID-19) en niños, niñas y adolescentes en el Caribe. La investigación consistió en un estudio descriptivo y transversal que incluyó a 15 países o territorios del Caribe y empleó encuestas y fuentes de datos secundarios. Las medidas de cuarentena y aislamiento fueron sólidas, igual que las estrategias de vigilancia. Había especialistas pediátricos disponibles en toda la región, pero pocos designados en hospitales pediátricos o unidades de alta dependencia. Hubo más casos en pacientes pediátricos en las islas más pobladas. En comparación con los países y territorios de ingresos altos, los de ingresos medianos altos y medianos bajos presentaron una mayor carga de morbilidad, menos personal médico y de enfermería por 1 000 habitantes, menor capacidad de camas y menor cobertura de vacunación. Los casos de niños, niñas y adolescentes oscilaron entre 0,60% y 16,9%, en comparación con una tasa general de casos de 20,2% en el 2021. En agosto del 2021, hubo 33 muertes de pacientes pediátricos de Haití, Jamaica, Trinidad y Tabago y Barbados. Las tasas de mortalidad de los grupos etarios de 0 a 9 años y de 10 a 19 años fueron respectivamente de 2,80 y 0,70 en Haití; 0,10 y 0,20 en Jamaica; y 0,00 y 0,14 en Trinidad; en comparación con 0,17 y 0,1 a nivel mundial. La incidencia general de COVID-19 y la mortalidad en la población infantil fueron coherentes con las estimaciones mundiales. Se compensaron los recursos limitados con la disponibilidad de pediatras en toda la región y efectos directos mínimos en los niños. Priorizar la admisión de grupos específicos de riesgo, la capacitación de los equipos de respuesta inicial y las campañas de vacunación dirigidas a mujeres embarazadas y niños, niñas y adolescentes vulnerables podría beneficiar a los países con recursos limitados y bajas tasas de cobertura de vacunación.

Este estudo visa a avaliar os métodos de vigilância, recursos de saúde, cobertura vacinal e estratificação de renda relacionados à doença do coronavírus de 2019 (COVID-19) e quantificar a carga de morbimortalidade a ela atribuível em crianças e adolescentes no Caribe. Foi realizado um estudo descritivo e transversal que incluiu 15 países e territórios caribenhos e utilizaram-se levantamentos e fontes de dados secundárias. As medidas de quarentena e isolamento foram robustas, e as estratégias de vigilância foram semelhantes. Houve disponibilidade de especialistas pediátricos em toda a região, mas poucos países/territórios tinham hospitais pediátricos ou unidades semi-intensivas especificamente designados. Ocorreram mais casos em crianças nas ilhas com populações maiores. Em comparação com os países/territórios de alta renda, aqueles de renda média-alta e média-baixa apresentaram uma maior carga de morbidade, menos médicos e enfermeiros por 1 000 habitantes, menor capacidade de leitos e menor cobertura vacinal. De 0,60% a 16,9% dos casos ocorreram em crianças e adolescentes, contra uma média mundial de 20,2% em 2021. Até agosto de 2021, haviam ocorrido 33 óbitos de crianças em Barbados, Haiti, Jamaica e Trinidad e Tobago. Os respectivos índices de letalidade nas faixas etárias de 0-9 anos e de 10-19 anos foram 2,80 e 0,70 no Haiti, 0,10 e 0,20 na Jamaica e 0,00 e 0,14 em Trinidad, em comparação com 0,17 e 0,1 no âmbito mundial. Em geral, a incidência e a mortalidade por COVID-19 em crianças foram condizentes com as estimativas mundiais. Os recursos limitados foram compensados pela disponibilidade de pediatras em toda a região e pelos pouquíssimos efeitos diretos sobre as crianças. Priorização de grupos de risco específicos para internação, treinamento de socorristas e campanhas de vacinação dirigidas a gestantes e a crianças e adolescentes vulneráveis poderiam beneficiar países com baixos índices de cobertura vacinal e recursos limitados.

Newborn screening for abnormal haemoglobins in Jamaica: Practical issues in an island programme.

OBJECTIVE: To report the diagnostic challenges of newborn screening for abnormal haemoglobins. SETTING: Cord blood samples from 13 hospitals in southwest Jamaica taken in 2008-2019. METHODS: Blood spots, collected from the umbilical cord, were analysed by high pressure liquid chromatography (HPLC) to reveal phenotypes for HbSS and HbCC, but genotype confirmation may require parental studies or gene sequencing. Such cases that were successfully traced were analysed in this follow-up study. RESULTS: HPLC screening of 121,306 samples detected HbAS in 11,846 (9.8%), HbAC in 4508 (3.7%) and other electrophoretic abnormalities in 1090 babies. Among 101 previously unconfirmed cases, 34/90 (38%) with HPLC evidence of a HbSS phenotype had other genotypes, and 7/11 (64%) with a HbCC phenotype had other genotypes. Syndromes from the interaction of ß thalassaemia occurred in 112 babies (85 with HbS, 27 with HbC) and of genes for hereditary persistence of fetal haemoglobin (HPFH) in 18 (12 with HbS, 6 with HbC). Variants other than HbS and HbC occurred in 270 babies, 16 in combination with either HbS or HbC, and 254 as traits. Most variants are benign even when inherited with HbS, although HbO Arab, HbD Punjab, or Hb Lepore Washington, which occurred in 6 cases, may cause sickle cell disease. CONCLUSIONS: Genes for ß thalassaemia and HPFH are common in western Jamaica and when associated with HbS may present diagnostic challenges in newborns, as HbF and HbA2 have not reached diagnostic levels. Family and DNA studies may be necessary for genotype confirmation.

Interventions and policies aimed at improving nutrition in Small Island Developing States: a rapid review.

Objective: To describe features of nutritional interventions implemented in Small Island Developing States (SIDS) in the past 20 years. Methods: A rapid scoping review was conducted by searching PubMed and Web of Science databases for interventions conducted in SIDS that sought to improve the nutrition of their populations between 2000 and 2019 inclusive. The Noncommunicable diseases progress monitor 2020 was also examined to assess nutritional policies in SIDS. Results: A total of 174 interventions were implemented in 49 of the 58 SIDS. The greatest proportion were conducted in the Caribbean (75 interventions; 43%), with the Pacific region, and the Atlantic, Indian Ocean, Mediterranean and South China Sea region each implementing about 30% of interventions. Using the NOURISHING framework, most interventions (67%) were implemented at the community and national or policy level, using multiple components of the framework. The greatest proportion of interventions (35%) were educational and awareness raising. Restrictions on physical availability of and increased taxation on alcohol were the most commonly reported policies that were partially or fully achieved; restrictions on fats were the least commonly reported. These findings were generally consistent across the SIDS regions. Conclusions: There is a paucity of nutritional policies in SIDS; the reasons may be linked to their social, economic, and environmental vulnerabilities. Interventions should be expanded beyond education to encompass multiple components of the NOURISHING framework, with multisectoral inclusion to ensure stronger stakeholder collaboration and buy-in. A systematic review is warranted using a fuller range of sources to assess the effectiveness of interventions.

Children and the coronavirus disease 2019 pandemic: a Caribbean perspective

[ABSTRACT]. This study aims to assess coronavirus disease 2019 (COVID-19) surveillance methods, health resources, vaccination coverage and income stratification and quantify burdens of disease and death in children and adolescents in the Caribbean. The investigation was a descriptive, cross-sectional study that included 15 Caribbean countries/territories and utilized surveys and secondary data sources. Quarantine and isolation measures were robust and surveillance strategies were similar. Pediatric specialists were available across the region, but few had designated pediatric hospitals or high-dependency units. There were more cases in children on islands with larger populations. Compared to high-income countries/territories, upper and lower middle-income countries/territories had higher disease burdens, fewer doctors and nurses per 1 000 population, lower bed capacities, and lower vaccination coverage. Child and adolescent cases ranged from 0.60% to 16.9%, compared with a global case rate of 20.2% in 2021. By August 2021 there were 33 deaths among children from Haiti, Jamaica, Trinidad and Tobago, and Barbados. The respective case fatality rates for 0–9-year-olds and 10–19-year-olds were 2.80 and 0.70 in Haiti, 0.10 and 0.20 in Jamaica, and 0.00 and 0.14 in Trinidad, compared with 0.17 and 0.1 globally. Overall COVID-19 incidence and mortality in children were consistent with global estimates. Limited resources have been offset by availability of pediatricians across the region, and minimally direct effects on children. Prioritization of admission of specific at-risk groups, training of first responders and vaccination campaigns targeting pregnant women and vulnerable children and adolescents could benefit countries with low vaccine coverage rates and limited resources.

[RESUMEN]. El presente estudio tiene como objetivo evaluar los métodos de vigilancia, los recursos de salud, y la cobertura de vacunación y la estratificación de los ingresos, así como cuantificar las cargas de enfermedad y muerte de la enfermedad por coronavirus del 2019 (COVID-19) en niños, niñas y adolescentes en el Caribe. La investigación consistió en un estudio descriptivo y transversal que incluyó a 15 países o territorios del Caribe y empleó encuestas y fuentes de datos secundarios. Las medidas de cuarentena y aislamiento fueron sólidas, igual que las estrategias de vigilancia. Había especialistas pediátricos disponibles en toda la región, pero pocos designados en hospitales pediátricos o unidades de alta dependencia. Hubo más casos en pacientes pediátricos en las islas más pobladas. En comparación con los países y territorios de ingresos altos, los de ingresos medianos altos y medianos bajos presentaron una mayor carga de morbilidad, menos personal médico y de enfermería por 1 000 habitantes, menor capacidad de camas y menor cobertura de vacunación. Los casos de niños, niñas y adolescentes oscilaron entre 0,60% y 16,9%, en comparación con una tasa general de casos de 20,2% en el 2021. En agosto del 2021, hubo 33 muertes de pacientes pediátricos de Haití, Jamaica, Trinidad y Tabago y Barbados. Las tasas de mortalidad de los grupos etarios de 0 a 9 años y de 10 a 19 años fueron respectivamente de 2,80 y 0,70 en Haití; 0,10 y 0,20 en Jamaica; y 0,00 y 0,14 en Trinidad; en comparación con 0,17 y 0,1 a nivel mundial. La incidencia general de COVID-19 y la mortalidad en la población infantil fueron coherentes con las estimaciones mundiales. Se compensaron los recursos limitados con la disponibilidad de pediatras en toda la región y efectos directos mínimos en los niños. Priorizar la admisión de grupos específicos de riesgo, la capacitación de los equipos de respuesta inicial y las campañas de vacunación dirigidas a mujeres embarazadas y niños, niñas y adolescentes vulnerables podría beneficiar a los países con recursos limitados y bajas tasas de cobertura de vacunación.

[RESUMO]. Este estudo visa a avaliar os métodos de vigilância, recursos de saúde, cobertura vacinal e estratificação de renda relacionados à doença do coronavírus de 2019 (COVID-19) e quantificar a carga de morbimortalidade a ela atribuível em crianças e adolescentes no Caribe. Foi realizado um estudo descritivo e transversal que incluiu 15 países e territórios caribenhos e utilizaram-se levantamentos e fontes de dados secundárias. As medidas de quarentena e isolamento foram robustas, e as estratégias de vigilância foram semelhantes. Houve disponibilidade de especialistas pediátricos em toda a região, mas poucos países/territórios tinham hospitais pediátricos ou unidades semi-intensivas especificamente designados. Ocorreram mais casos em crianças nas ilhas com populações maiores. Em comparação com os países/territórios de alta renda, aqueles de renda média-alta e média-baixa apresentaram uma maior carga de morbidade, menos médicos e enfermeiros por 1 000 habitantes, menor capacidade de leitos e menor cobertura vacinal. De 0,60% a 16,9% dos casos ocorreram em crianças e adolescentes, contra uma média mundial de 20,2% em 2021. Até agosto de 2021, haviam ocorrido 33 óbitos de crianças em Barbados, Haiti, Jamaica e Trinidad e Tobago. Os respectivos índices de letalidade nas faixas etárias de 0-9 anos e de 10-19 anos foram 2,80 e 0,70 no Haiti, 0,10 e 0,20 na Jamaica e 0,00 e 0,14 em Trinidad, em comparação com 0,17 e 0,1 no âmbito mundial. Em geral, a incidência e a mortalidade por COVID-19 em crianças foram condizentes com as estimativas mundiais. Os recursos limitados foram compensados pela disponibilidade de pediatras em toda a região e pelos pouquíssimos efeitos diretos sobre as crianças. Priorização de grupos de risco específicos para internação, treinamento de socorristas e campanhas de vacinação dirigidas a gestantes e a crianças e adolescentes vulneráveis poderiam beneficiar países com baixos índices de cobertura vacinal e recursos limitados.

Interventions and policies aimed at improving nutrition in Small Island Developing States: a rapid review

[ABSTRACT]. Objective. To describe features of nutritional interventions implemented in Small Island Developing States (SIDS) in the past 20 years. Methods. A rapid scoping review was conducted by searching PubMed and Web of Science databases for interventions conducted in SIDS that sought to improve the nutrition of their populations between 2000 and 2019 inclusive. The Noncommunicable diseases progress monitor 2020 was also examined to assess nutritional policies in SIDS. Results. A total of 174 interventions were implemented in 49 of the 58 SIDS. The greatest proportion were conducted in the Caribbean (75 interventions; 43%), with the Pacific region, and the Atlantic, Indian Ocean, Mediterranean and South China Sea region each implementing about 30% of interventions. Using the NOURISHING framework, most interventions (67%) were implemented at the community and national or policy level, using multiple components of the framework. The greatest proportion of interventions (35%) were educational and awareness raising. Restrictions on physical availability of and increased taxation on alcohol were the most commonly reported policies that were partially or fully achieved; restrictions on fats were the least commonly reported. These findings were generally consistent across the SIDS regions. Conclusions. There is a paucity of nutritional policies in SIDS; the reasons may be linked to their social, economic, and environmental vulnerabilities. Interventions should be expanded beyond education to encompass multiple components of the NOURISHING framework, with multisectoral inclusion to ensure stronger stakeholder collaboration and buy-in. A systematic review is warranted using a fuller range of sources to assess the effectiveness of interventions.

[RESUMEN]. Objetivo. Describir las características de las intervenciones nutricionales realizadas en los pequeños Estados insulares en desarrollo durante los últimos 20 años. Métodos. Se realizó una revisión exploratoria rápida mediante búsquedas en las bases de datos PubMed y Web of Science de las intervenciones realizadas en los pequeños Estados insulares en desarrollo entre los años 2000 y 2019 con el fin de mejorar la nutrición de su población. También se examinó la publicación Monitoreo de avances en materia de las enfermedades no transmisibles 2020 para evaluar las políticas nutricionales en estos Estados. Resultados. Se efectuaron 174 intervenciones en 49 de los 58 pequeños Estados insulares en desarrollo. La mayor parte se llevaron a cabo en el Caribe (75 intervenciones; 43%), en tanto que la región del Pacífico y la región de los océanos Atlántico e Índico y de los mares de China Meridional y Mediterráneo efectuaron aproximadamente un 30% de las intervenciones cada una. Con la ayuda del marco NOURISHING, la mayor parte de las intervenciones (67%) se efectuaron a nivel de la comunidad y a nivel de país o de política utilizando distintos componentes del marco. La mayor parte de las intervenciones (35%) fueron educativas y de concientización. Entre las políticas que se notificaron con más frecuencia estuvieron las restricciones a la disponibilidad física de las bebidas alcohólicas y el aumento de los impuestos al alcohol; entre las menos frecuentes, las restricciones a las grasas. Por lo general, estos resultados fueron uniformes en todas las regiones con pequeños Estados insulares en desarrollo. Conclusiones. Los pequeños Estados insulares en desarrollo tienen pocas políticas nutricionales; esto puede estar relacionado con sus vulnerabilidades sociales, económicas y ambientales. Las intervenciones deberían ampliarse más allá de la educación para así incorporar múltiples componentes del marco NOURISHING, con una inclusión multisectorial que garantice una mayor colaboración y aceptación de las partes interesadas. Se justifica una revisión sistemática que haga uso de una gama más completa de fuentes para evaluar la efectividad de las intervenciones.

[RESUMO]. Objetivo. Descrever as características das intervenções nutricionais implementadas em pequenos Estados insulares em desenvolvimento (PEID) nos 20 últimos anos. Métodos. Uma revisão de escopo rápida foi realizada mediante pesquisa dos bancos de dados PubMed e Web of Science, buscando intervenções para melhoria nutricional da população em PEID no período entre 2000 e 2019. A publicação Noncommunicable Diseases Progress Monitor 2020 também foi consultada para avaliar as políticas nutricionais destes países. Resultados. Foram implementadas 174 intervenções em 49 dos 58 PEID, distribuídas na sua grande maioria na região do Caribe (75, 43%) e nas regiões do Pacífico e AIMS (Atlântico, Índico, Mediterrâneo e Mar do Sul da China) (cerca de 30% cada). Elaboradas a partir do NOURISHING Framework, a maior parte das intervenções (67%) teve implementação ao nível nacional, da comunidade ou de política, englobando os vários componentes deste quadro. Houve predomínio de intervenções educacionais e de sensibilização (35%). Observou-se com maior frequência o cumprimento total ou parcial de políticas de restrição à oferta física de bebidas alcoólicas e aumento de impostos sobre estas. Políticas de restrição à utilização de gorduras em alimentos foram as menos observadas. Em geral, as conclusões foram semelhantes em todas as regiões de PEID. Conclusões. Os PEID carecem de políticas nutricionais, devido a fatores possivelmente associados a vulnerabilidades ambientais e socioeconômicas. Além de educacionais, as intervenções devem ser ampliadas para englobar diversos outros componentes do NOURISHING Framework, com participação multissetorial para assegurar uma maior colaboração e comprometimento das partes envolvidas. Recomenda-se realizar uma revisão sistemática, com pesquisa de um rol mais amplo de fontes de informação, para avaliar a efetividade das intervenções.

Dietary Patterns, Food Insecurity, and Their Relationships with Food Sources and Social Determinants in Two Small Island Developing States.

Small Island Developing States (SIDS) have high burdens of nutrition-related chronic diseases. This has been associated with lack of access to adequate and affordable nutritious foods and increasing reliance on imported foods. Our aim in this study was to investigate dietary patterns and food insecurity and assess their associations with socio-demographic characteristics and food sources. We recruited individuals aged 15 years and above from rural and urban areas in Fiji (n = 186) and St. Vincent and the Grenadines (SVG) (n = 147). Data collection included a 24 h diet recall, food source questionnaire and the Food Insecurity Experience Scale. We conducted latent class analysis to identify dietary patterns, and multivariable regression to investigate independent associations with dietary patterns. Three dietary patterns were identified: (1) low pulses, and milk and milk products, (2) intermediate pulses, and milk and milk products and (3) most diverse. In both SIDS, dietary pattern 3 was associated with older age, regularly sourcing food from supermarkets and borrowing, exchanging, bartering or gifting (BEB). Prevalence of food insecurity was not statistically different across dietary patterns. In both SIDS, food insecurity was higher in those regularly sourcing food from small shops, and in SVG, lower in those regularly using BEB. These results complement previous findings and provide a basis for further investigation into the determinants of dietary patterns, dietary diversity and food insecurity in these settings.

Adaptation of a community-based type-2 diabetes mellitus remission intervention during COVID-19: empowering persons living with diabetes to take control.

BACKGROUND: The Barbados Diabetes Remission Study-2 reported that a low-calorie diet for weight loss and diabetes remission implemented within the community and supported by trained community health advocates was both an acceptable implementation strategy and a clinically effective intervention. This study aimed to examine the adaptability of the face-to-face protocol into an online modality. METHODS: The Iterative Decision-making for Evaluation of Adaptations (IDEA) framework guides researchers in examining the necessity of the adaptation and the preservation of core intervention elements during the adaptation process. Adaptation outcomes were documented using the Framework for Reporting Adaptations and Modifications to Evidence-Based Implementation Strategies (FRAME-IS). Implementation outcome was determined by fidelity to core elements. Intervention effectiveness was determined from the analysis of clinical data. RESULTS: We decided that an adaptation was needed as COVID-19 control measures prohibited in-person interactions. The core elements-i.e. 12-week intervention duration, daily 840-kcal allowance, and weekly monitoring of weight and blood glucose-could be preserved during the adaptation process. Adaptations were made to the following: (1) the context in which data were collected-participants self-measured at home instead of following the original implementation strategy which involved being measured by community health advocates (CHA) at a community site; (2) the context in which data were entered-participants posted their measurements to a mobile application site which was accessible by CHAs. As with the original protocol, CHAs then entered the measurements into an online database; (3) the formulation of the low-calorie diet-participants substituted the liquid formulation for a solid meal plan of equivalent caloric content. There was non-inferiority in fidelity to attendance with the online format (97.5% visit rate), as compared to the face-to-face modality (95% visit rate). One participant deviated from the calorie allowances citing difficulty in estimating non-exact portion sizes and financial difficulty in procuring meals. Weight change ranged from - 14.3 to 0.4 kg over the 12-week period, and all group members achieved induction of diabetes remission as determined by a FBG of < 7mmol/l and an A1C of < 6.5%. CONCLUSION: The results suggest that this adapted online protocol-which includes changes to both the implementation strategy and the evidence-based practice-is clinically effective whilst maintaining fidelity to key elements. Utilization of the IDEA and FRAME-IS adaptation frameworks add scientific rigour to the research. TRIAL REGISTRATION: ClinicalTrials.gov NCT03536377 . Registered on 24 May 2018.

Socioeconomic and gendered inequities in travel behaviour in Africa: Mixed-method systematic review and meta-ethnography.

Travel has individual, societal and planetary health implications. We explored socioeconomic and gendered differences in travel behaviour in Africa, to develop an understanding of travel-related inequity. We conducted a mixed-methods systematic review (PROSPERO CRD42019124802). In 2019, we searched MEDLINE, TRID, SCOPUS, Web of Science, LILACS, SciELO, Global Health, Africa Index Medicus, CINAHL and MediCarib for studies examining travel behaviour by socioeconomic status and gender in Africa. We appraised study quality using Critical Appraisal Skills Programme checklists. We synthesised qualitative data using meta-ethnography, followed by a narrative synthesis of quantitative data, and integrated qualitative and quantitative strands using pattern matching principles. We retrieved 103 studies (20 qualitative, 24 mixed-methods, 59 quantitative). From the meta-ethnography, we observed that travel is: intertwined with social mobility; necessary to access resources; associated with cost and safety barriers; typified by long distances and slow modes; and dictated by gendered social expectations. We also observed that: motorised transport is needed in cities; walking is an unsafe, 'captive' mode; and urban and transport planning are uncoordinated. From these observations, we derived hypothesised patterns that were tested using the quantitative data, and found support for these overall. In lower socioeconomic individuals, travel inequity entailed reliance on walking and paratransit (informal public transport), being unable to afford travel, travelling less overall, and travelling long distances in hazardous conditions. In women and girls, travel inequity entailed reliance on walking and lack of access to private vehicles, risk of personal violence, societally-imposed travel constraints, and household duties shaping travel. Limitations included lack of analytical rigour in qualitative studies and a preponderance of cross-sectional quantitative studies (offering a static view of an evolving process). Overall, we found that travel inequity in Africa perpetuates socioeconomic and gendered disadvantage. Proposed solutions focus on improving the safety, efficiency and affordability of public transport and walking.
