Plantocratic patriarchal culture, violence against women and girls and the failures of the global health system: an interview with Marsha Hinds Myrie and Anya A. A. Lorde.

Like other parts of the world, women and girls in the Commonwealth Caribbean (CC) experience high and escalating rates of physical and sexual violence. The interview presented outlines some factors that underscore the gendered disparities of violence against women in the Caribbean as well as how healthcare responses are not developed for marginalised women and girls. The interview explores the invisibility of women and girls within healthcare and broader national healthcare structures responses through case details analysis of a Barbadian strategic litigation case. The interview calls for transdisciplinary approaches to analysing the effectiveness of the global health system that make space for not just traditional research approaches but also lived experiences 'from below' and input of advocates and activists. Despite Barbados being a signatory to a range of global health initiatives to improve healthcare responses to gender-based violence, the country does not have a formalised, comprehensive national plan to inform prevention and intervention measures. The interview shows the connections between plantocratic patriarchal culture (PPC) and the existing gaps that cause harm to women and girls who experience various types of gendered violence.

Innovative spectral characterisation of beached pelagic sargassum towards remote estimation of biochemical and phenotypic properties.

In recent years, pelagic sargassum (S. fluitans and S. natans - henceforth sargassum) macroalgal blooms have become more frequent and larger with higher biomass in the Tropical Atlantic region. They have environmental and socio-economic impacts, particularly on coastal ecosystems, tourism, fisheries and aquaculture industries, and on public health. Despite these challenges, sargassum biomass has the potential to offer commercial opportunities in the blue economy, although, it is reliant on key chemical and physical characteristics of the sargassum for specific use. In this study, we aim to utilise remotely sensed spectral profiles to determine species/morphotypes at different decomposition stages and their biochemical composition to support monitoring and valorisation of sargassum. For this, we undertook dedicated field campaigns in Barbados and Ghana to collect, for the first time, in situ spectral measurements between 350 and 2500 nm using a Spectra Vista Corp (SVC) HR-1024i field spectrometer of pelagic sargassum stranded biomass. The spectral measurements were complemented by uncrewed aerial system surveys using a DJI Phantom 4 drone and a DJI P4 multispectral instrument. Using the ground and airborne datasets this research developed an operational framework for remote detection of beached sargassum; and created spectral profiles of species/morphotypes and decomposition maps to infer biochemical composition. We were able to identify some key spectral regions, including a consistent absorption feature (920-1080 nm) found in all of the sargassum morphotype spectral profiles; we also observed distinction between fresh and recently beached sargassum particularly around 900-1000 nm. This work can support pelagic sargassum management and contribute to effective utilisation of the sargassum biomass to ultimately alleviate some of the socio-economic impacts associated with this emerging environmental challenge.

Female Leadership during COVID-19: The Effectiveness of Diverse Approaches towards Mitigation Management during a Pandemic.

This paper tackles the question of how female leaders at national levels of government managed COVID-19 response and recovery from the first COVID-19 case in their respective countries through to 30 September 2021. The aim of this study was to determine which COVID-19 mitigations were effective in lowering the viral reproduction rate and number of new cases (per million) in each of the fourteen female presidents' countries-Bangladesh, Barbados, Belgium, Bolivia, Denmark, Estonia, Finland, Germany, Iceland, Lithuania, New Zealand, Norway, Serbia, and Taiwan. We first compared these countries by finding a mean case rate (29,420 per million), mean death rate (294 per million), and mean excess mortality rate (+1640 per million). We then analyzed the following mitigation measures per country: school closing, workplace closing, canceling public events, restrictions on gatherings, closing public transport, stay-at-home requirements, restrictions on internal movement, international travel controls, income support, debt/contract relief, fiscal measures, international support, public information campaigns, testing policy, contact tracing, emergency investment in healthcare, investment in vaccines, facial coverings, vaccination policy, and protection of the elderly. We utilized the random forest approach to examine the predictive significance of these variables, providing more interpretability. Subsequently, we then applied the Wilcoxon rank-sum statistical test to see the differences with and without mitigation in effect for the variables that were found to be significant by the random forest model. We observed that different mitigation strategies varied in their effectiveness. Notably, restrictions on internal movement and the closure of public transportation proved to be highly effective in reducing the spread of COVID-19. Embracing qualities such as community-based, empathetic, and personable leadership can foster greater trust among citizens, ensuring continued adherence to governmental policies like mask mandates and stay-at-home orders, ultimately enhancing long-term crisis management.

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.

Real-World Data and Paper-Based Disease Registries in the Small Island Developing State of Barbados During the COVID-19 Pandemic.

Significant data is being produced on the impact of COVID-19 on aspects of clinical care. However, less is known about the impact on real-world health data. The US Food and Drug Administration defines real-world data as "data relating to patient health status and/or the delivery of health care routinely collected from a variety of sources," including disease registries.1 The methodology used by the Barbados National Registry (BNR)-active pursuit of first-hand clinical data using paper-based charts from multiple sources-makes it an ideal example of real-world data. Real-world data can overcome the barriers to clinical trials often present in small island developing states. This paper reviews the impact of the COVID-19 pandemic on the data of the BNR within the context of the real-world data cycle. Data collected retrospectively for 2016-2018, undergoing traceback during the pandemic, demonstrated a greater reliance on death certificate registration. A 38% reduction in the collection of new cases was noted in the postpandemic period compared to data collected in previous periods. The lack of access to source data delayed cancer registry reporting. We conclude that, given the challenges highlighted during the COVID-19 pandemic, more effort should be placed on providing timely access to real-world data for public health decision-making, particularly in small island developing states.

Preexposure Prophylaxis in Latin America and the Caribbean-The Barbados Experience.

This study explored oral pre-exposure prophylaxis (PrEP) awareness, and sexual behavior of gay, bisexual, and other men who have sex with men (gbMSM) in Barbados. Factors associated with PrEP use were examined using Pearson chi-square and logistic regression. Of the 171 male participants who completed the survey, 22% were under 25 years old, 70% identified as gay/homosexual, and 59% were single. PrEP awareness was 77%, and of these 29% were current PrEP users. Users were more likely to have stable living arrangements (p < .05) and to identify as gay/homosexual (p=.03). Uptake by current PrEP users was attributed to non-judgmental and confidential PrEP services. Barriers identified by former PrEP users included cost and risks of STIs. Since the PrEP program is free, as is general health care for STIs, this suggests that there may be a knowledge gap. Further studies are needed to explore perceived barriers to the program.

Checklist of the shallow-water marine Brachyura (Crustacea: Decapoda) of Barbados, West Indies.

Here we provide an illustrated and annotated checklist of brachyuran crabs associated with shallow water marine habitats (nearshore rubble and subtidal) in Barbados, West Indies (13.1939°N, 59.5432°W). Twenty-one (21) survey sites in nearshore rubble and shallow subtidal habitats were surveyed between October 2018 to September 2021. Nearshore rubble habitats were surveyed at low tide during the day and night periods. Shallow nearshore subtidal habitats were surveyed every 9-12 days from February to October 2019 using crab traps placed ~ 4 m deep on sandy and rocky bottoms. A total of 1,640 specimens were recorded, belonging to nine (9) superfamilies, 14 families, 34 genera, and 44 species. The genera Charybdis De Haan, 1833, Pitho Bell, 1835, Thoe Bell, 1835, and Uhlias Stimpson, 1871 are here reported for the first time for Barbados. Thirteen (13) species are first records for Barbados, thus extending their geographic range. The most abundant and widespread species collected was Mithraculus coryphe Herbst, 1801, which accounted for 35% (N = 570) of the specimens, occurring in both nearshore rubble and subtidal habitats.

An analysis of arsenic concentrations associated with sargassum influx events in Barbados.

Tropical Atlantic blooms of pelagic Sargassum spp. present major socioeconomic and ecological challenges for Caribbean and West African nations. Valorisation of sargassum provides an opportunity to ameliorate some of the damage to national economies; however, the active uptake of arsenic by pelagic sargassum creates significant barriers to its use. When defining valorisation pathways, it is important to understand arsenic speciation in pelagic sargassum, given the different levels of toxicity associated with different arsenic species. In this study, we assess the temporal variability of total arsenic and inorganic arsenic in pelagic sargassum arriving in Barbados; and test whether arsenic concentrations are linked to oceanic sub-origins. Results indicate that inorganic arsenic, the most toxic form, represents a consistent and substantial percentage of the total arsenic present in pelagic sargassum, and that variability in arsenic concentration does not appear to be driven by sample months, years or oceanic sub-origins/transport pathways.

Incidence, prevalence, and potential risk factors for diabetic foot ulceration: A retrospective review at a multidisciplinary centre in Barbados.

OBJECTIVE: Diabetes and lower extremity amputation rates in Barbados are among some of the highest globally, with peripheral neuropathy and peripheral vascular disease found to be independent risk factors for this population. Despite this, there is currently a lack of research evidence on rates of diabetic foot ulceration, which has amputation as its sequela. We aimed to evaluate the incidence and prevalence rates of active ulceration in a population of people with diabetes in Barbados. Secondly, we explored the risk factors for new/recurrent ulceration. RESEARCH DESIGN AND METHODS: Data were extracted from the electronic medical records for the period January 1, 2019 to December 31, 2020 for a retrospective cross-sectional study for patients of a publicly-funded diabetes management programme. Eligible records included people aged 18 years and above with a diagnosis of type 1 or 2 diabetes. Potential risk factors were explored using univariable logistic regression models. RESULTS: A total of 225 patients were included in the study (96% type 2 diabetes, 70.7% female, 98.7% Black Caribbean). The 1-year period prevalence of diabetic foot ulceration was 14.7% (confidence interval [CI]: 10.5, 20.1). Incidence of ulceration in the same period was 4.4% (CI: 4.4, 4.5). Risk factors associated with diabetic foot ulceration included: retinopathy (OR 3.85, CI: 1.24, 11.93), chronic kidney disease (OR 9.86, CI: 1.31, 74.22), aspirin use (OR 3.326, CI: 1.02, 10.85), and clopidogrel use (OR 3.13, CI: 1.47, 6.68). CONCLUSION: This study provided some insight into potential risk factors for foot ulceration in this population, which previous studies have shown to have higher rates of lower extremity amputations. Further research in this understudied group through a larger prospective cohort would allow more meaningful associations with risk factors and would be useful for the creation of risk prediction models.

Companions' Chronicles: Experiences of Home Care Workers in the Community Elder Care (Companion) Program in Barbados.

The home care workforce contributes significantly to older adults' health and well-being. The Community Elder Care (Companion) Program in Barbados employs Companions to engage with socially isolated older adults in their homes for a few hours per day. In this qualitative study we explored Companions' experiences in the program 1 year since its commencement. Opportunity to earn, love and concern for older adults, and previous caregiving experiences were among the factors which motivated participants to seek employment in the program. They commonly reported going beyond the scope of their duties to meet clients' critical needs. While they saw themselves as positively impacting their clients, some noted that they too benefitted from the engagement. Better compensation packages and training were seen as necessary actions for program improvement. Our findings can be incorporated in a comprehensive program review and can inform home care workforce development and Companion Program structure and delivery.

The Intimate Relationship Experiences of Women Engaged in Transactional Sex Work in Barbados.

This phenomenological study, consisting of individual interviews with a sample of 30 women engaged in sex work, examines the intimate relationships of women engaged in sex work in Barbados. Participants often entered relationships with men they met while engaged in sex work. Most experienced relationships that became transactional, abusive, and exploitative. Intimate partner violence (IPV) challenged their ability to negotiate condom use with intimate partners placing them at risk for HIV. A cycle emerged of entering relationships to exit the violent conditions of sex work and then re-entering sex work to escape IPV. Implications for mental health, HIV prevention, IPV, and empowerment services are described.

Personal protective equipment (PPE) related adverse skin reactions among healthcare workers at the main COVID-19 isolation center in Barbados.

Background: The use of personal protective equipment (PPE) reduces the risk of transmission of infectious agents significantly among healthcare workers (HCWs). The study aimed to investigate the prevalence and characteristics of PPE-related adverse skin reactions among HCWs working at the main COVID-19 isolation center in Barbados. Methods: A cross-sectional web-based online survey was conducted during April to June 2021 which recorded demographic information, details of PPE use and adverse skin reactions including severity and duration of onset of symptoms. Results: Most of the respondents used PPE for consecutive days (77.9%), 1-6 h/day (59.2%), and more than a year (62.5%). Fewer than half of the participants (45.6%) experienced adverse skin reactions from the use of PPE. The reactions were mostly observed in the cheeks (40.4%) and nose bridges (35.6%). Females had more reactions than their male counterparts (p = 0.003). The use of N95 masks and a combination of surgical and N95 masks produced adverse effects predominantly in the ears (60%) and cheeks (56.4%). Binary logistic regression showed that female HCWs (OR = 5.720 95% CI: 1.631, 20.063), doctors (OR = 5.215 95% CI: 0.877, 31.002), and longer duration of PPE use (>1 year) (OR = 2.902 95% CI: 0.958, 8.787) caused a significantly higher prevalence of adverse skin reactions. Conclusion: The PPE-related skin reactions were common among HCWs which mainly occurred due to prolonged use. Preventive measures inclusive of appropriate training of HCWs on the use of PPE are recommended to minimize these adverse events.

Retrospective analysis of endometrial cancer among Afro-Caribbean women in Barbados 2008-2017.

Endometrial cancer data amongst Barbadian women was collected, to inform screening and management in this under-studied population. We analysed all recorded primary cases between January 1st 2008, and December 31st, 2017. Age-specific incidence, and crude mortality rates were calculated. Descriptive statistics characterized demographics, risk factors, prescription data and histopathology. Log-rank tests assessed simple group differences by EC type. Survival analysis based on tumour type was plotted using Kaplein-Meir curves. There were 270 recorded cases of EC, averaging 66 (8.8) years old (SD 8.75), with parity of 3.60 (2.3). Cases were postmenopausal with 257 (95%) experiencing postmenopausal bleeding. Of the 270 cases, 113 (42%) had type 1 tumours and 157(58%) had type 2 tumours. Weak evidence suggests the latter imparted worse survival (log rank test = 0.02). Estimated crude incidence rate was 18.64 per 100,000 women. Crude mortality rate from EC between January 1st, 2008 and December 31st, 2019 was 27%.

Public Health Protection vs. Freedom of Commercial Expression in the Commonwealth Caribbean: The Case of Barbados and Jamaica.

This chapter explores the tension between public health protection and the freedom of commercial expression from a Commonwealth Caribbean perspective, using Barbados and Jamaica as case studies. First, it assesses the scope of the right to freedom of expression. Second, it discusses the extent to which public health protection may be invoked to restrict the right. The authors conclude that Commonwealth Caribbean states can justifiably restrict commercial speech about tobacco products and unhealthy food and beverages.

Peripheral Arterial Disease Prevalence in a Population-Based Sample of People with Diabetes on the Caribbean Island of Barbados.

Background: Peripheral arterial disease (PAD) is a risk factor for amputation and systemic atherosclerotic disease. Barbados has a high diabetes prevalence, and 89% of diabetes-related hospital admissions are for foot problems. Foot examination is infrequent in Barbados primary care. The prevalence and potential risk factors for PAD in people with diabetes in Barbados were studied. Methods: Multistage probability sampling was used to select a representative population sample of people ≥25 years of age with known diabetes or fasting blood glucose ≥7 mmol/L or HbA1c ≥6.5%. We administered the Edinburgh claudication questionnaire and assessed the ankle brachial pressure index (ABI) and Doppler waveform in both dorsalis pedis and posterior tibial arteries. Participants were classified into categories based on ABI as follows: PAD ≤0.90 in any leg; borderline 0.91 to 0.99 in one leg and the other not ≤0.90 or >0.4; normal 1.00 to 1.40 in both legs; and non-compressible >1.40 in one leg and the other not ≤0.9. Waveforms crossing the zero-flow baseline were categorised as normal. Multivariable logistic regression assessed the associations of potential risk factors with PAD. Results: Of 236 participants (74% response rate, 33% male, median age 58.6 years), 51% had previously diagnosed diabetes. Of nine people with symptoms of definite or atypical claudication, four had PAD and one had non-compressible arteries. ABI prevalence (95% CI) was PAD 18.6% (13.8, 24.6), borderline 21.9% (16.6, 28.4), normal 55.5% (49.4, 61.5) and non-compressible 3.9% (1.6, 9.3). Increasing age and female gender were independently associated with PAD. Over 80% of normal legs (ABI 1.00 to 1.40) had normal posterior tibial and dorsalis pedis waveforms, while only 23% legs with PAD (ABI ≤0.90) had normal waveforms in both arteries (Kappa = 0.43). Conclusion: Asymptomatic PAD is common in people with diabetes and requires ABI screening to detect it. Female gender is associated with PAD.

A closer look reveals hidden diversity in the intertidal Caribbean Fortuyniidae (Acari, Oribatida).

A molecular genetic and morphometric investigation revealed the supposedly widespread Caribbean and Western Atlantic intertidal oribatid mite species Fortuynia atlantica to comprise at least two different species. Although there are no distinct morphological differences separating these taxa, COI and 18S sequence divergence data, as well as different species delimitation analyses, clearly identify the two species. Fortuynia atlantica is distributed in the northern Caribbean and the Western Atlantic and the new Fortuynia antillea sp. nov. is presently endemic to Barbados. Vicariance is supposed to be responsible for their genetic diversification and stabilizing selection caused by the extreme intertidal environment is suggested to be the reason for the found morphological stasis. The genetic structure of Fortuynia atlantica indicates that Bermudian populations are derived from the northern Caribbean and thus support the theory of dispersal by drifting on the Gulf Stream. Haplotype network data suggest that Bermudian and Bahamian populations were largely shaped by colonization, expansion and extinction events caused by dramatic sea level changes during the Pleistocene. A preliminary phylogenetic analysis based on 18S gene sequences indicates that the globally distributed genus Fortuynia may be a monophyletic group, whereas Caribbean and Western Atlantic members are distinctly separated from the Indo-Pacific and Western Pacific species.

Analysis of the genomic landscapes of Barbadian and Nigerian women with triple negative breast cancer.

PURPOSE: Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype that disproportionately affects women of African ancestry (WAA) and is often associated with poor survival. Although there is a high prevalence of TNBC across West Africa and in women of the African diaspora, there has been no comprehensive genomics study to investigate the mutational profile of ancestrally related women across the Caribbean and West Africa. METHODS: This multisite cross-sectional study used 31 formalin-fixed paraffin-embedded (FFPE) samples from Barbadian and Nigerian TNBC participants. High-resolution whole exome sequencing (WES) was performed on the Barbadian and Nigerian TNBC samples to identify their mutational profiles and comparisons were made to African American, European American and Asian American sequencing data obtained from The Cancer Genome Atlas (TCGA). Whole exome sequencing was conducted on tumors with an average of 382 × coverage and 4335 × coverage for pooled germline non-tumor samples. RESULTS: Variants detected at high frequency in our WAA cohorts were found in the following genes NBPF12, PLIN4, TP53 and BRCA1. In the TCGA TNBC cases, these genes had a lower mutation rate, except for TP53 (32% in our cohort; 63% in TCGA-African American; 67% in TCGA-European American; 63% in TCGA-Asian). For all altered genes, there were no differences in frequency of mutations between WAA TNBC groups including the TCGA-African American cohort. For copy number variants, high frequency alterations were observed in PIK3CA, TP53, FGFR2 and HIF1AN genes. CONCLUSION: This study provides novel insights into the underlying genomic alterations in WAA TNBC samples and shines light on the importance of inclusion of under-represented populations in cancer genomics and biomarker studies.
