Attitudes Toward Transgender People Among Future Caribbean Doctors
The attitudes of medical students toward transgender people have important implications for the future quality of healthcare for Caribbean transgender patients. This paper examined the attitudes and beliefs of Caribbean medical students toward transgender people, provides psychometric evaluation of a promising instrument, and considers implications for the development of transgender curricula in Caribbean medical education. Medical students (
N
= 205; 155 women, 43 men, 7 unstated) enrolled at a publicly supported Caribbean university completed the Transgender Attitudes and Beliefs Scale (TABS; Kanamori et al., 2017). Internal consistency was strong for the total TABS (
α
= .93) and more variable for the three subscales: interpersonal comfort (IC:
α
= .91), sex/gender beliefs (SGB:
α
= .89), and human value (HV:
α
= .74). Confirmatory factor analysis demonstrated acceptable overall fit for the three-factor model. There were no significant gender differences in overall attitudes toward transgender people as measured by the total TABS score; women reported higher IC scores. Scores were not correlated with age or with year in medical school. Students reported significantly more tolerant attitudes on the HV scale than on IC or SGB scales. Psychometric findings establish measurement invariance and provide support for further use of the TABS in the Caribbean. We discuss implications for medical curriculum development, including use of the TABS as a tool for medical students to reflect on their individual attitudes and beliefs regarding transgender people.

Multiple Lenses to Unearth Hidden Voices: Living with Diabetic Foot Ulceration in an Afro-Caribbean Community
(1) Background: This study was conducted in the small island developing state of Barbados, which has dubiously earned the title of “amputation capital of the world”, to understand perspectives of persons living with diabetic foot ulceration. (2) Methods: An exploratory multi-lens approach was used (focus groups; dyads; and triads) to gather indigenous Afro-Caribbean perspectives of living with diabetic foot ulceration that may be obscured by using a single method. (3) Results: Findings in this group highlighted the necessity of creating culturally sensitive education tools, as well as understanding how mistrust of local health systems may play a role in decisions to delay seeking health services despite ease of access with no cost at point of care. Problematic historical relationships with health systems among Afro-Caribbean people, for whom oral traditions motivate preference for traditional medicines instead of Western/colonial treatments from North America or Europe, may be deeply entrenched in this population and contribute to health beliefs and behaviors. (4) Conclusions: This paper addresses the gap in the literature regarding the use of qualitative methodologies to explore the beliefs of Afro-Caribbean people within their native context to inform design of culturally responsive self-education programs.

Correction: Lovell et al. Multiple Lenses to Unearth Hidden Voices: Living with Diabetic Foot Ulceration in an Afro-Caribbean Community. Int. J. Environ. Res. Public Health 2025, 22, 304
A 2023 qualitative systematic review and meta-analysis exploring perceptions and experiences of persons with diabetes towards DFU highlighted four overarching themes: perceptions of DFUs (realization and reasons), coping with DFU (including persons’ behaviors towards treatment and management and perceptions towards amputation), expectations (expectation of health personnel and future expectation), and living with DFU (physical and emotion burdens, economic burdens, and change in life) [12]. Diasporic Afro-Caribbean populations in the United Kingdom living with type 2 diabetes have noted mistrust in medical systems and preference for natural remedies to traditional medical techniques as barriers to treatment [13].

Self-reported side effects of COVID-19 vaccines among health professions students in India
Studies focusing on the safety and common side effects of vaccines play a crucial role in enhancing public acceptance of vaccination. Research is scarce regarding the usage of COVID-19 vaccines and the side effects experienced by health professions students in India and other countries. This study aimed to document self-reported side effects associated with COVID-19 vaccination among medical and dental students of six medical and dental colleges and teaching hospitals in four states (Tamil Nadu, Madhya Pradesh, Gujarat, and West Bengal) of India. A cross-sectional survey using purposive sampling of medical and dental students was conducted from 26 April to 26 May 2021. Data was collected using a Google Forms questionnaire capturing information regarding receiving COVID-19 vaccines, side effects and symptoms, onset and duration of symptoms, use of treatment to alleviate symptoms, awareness of haematologic risks associated with vaccination, and side effects from previous (non-COVID-19) vaccinations. The majority (94.5%) of participants received both doses of the Covishield/AstraZeneca COVID-19 vaccine. Among participants ( n = 492), 45.3% ( n = 223) reported one or more side effects. The most frequently reported side effects were soreness of the injected arm (80.3%), tiredness (78.5%), fever (71.3%), headache (64.1%), and hypersomnia (58.7%). The two most common severe symptoms were fever (14.8%) and headache (13%). Most side effects appeared on the day of vaccination: soreness of the injection site (57%), fever (43.1%), and tiredness (42.6%). Most reported symptoms persisted for one to three days–soreness of the injection site (53%), fever (47.1%), and headache (42.6%). Logistic regression showed that women were almost 85% less likely to report side effects. The study’s findings corroborate the safety of the Covishield/AstraZeneca vaccine’s first dose, evidenced by the relatively minor and transient nature of the side effects. However, the study underscores the necessity for ongoing research to assess the long-term impacts of COVID-19 vaccines, especially in the context of booster doses, thereby contributing to the global understanding of vaccine safety and efficacy.

Knowledge, Attitudes, and Practices of Hand Hygiene, Mask Use, and Social Distancing among Public Hospital and Polyclinic Nurses in Barbados during the Coronavirus 2019 Pandemic
Background: Nurses are essential members of the healthcare workforce and were among the first-line carers for patients in community and hospital settings during the COVID-19 pandemic. As a result, they were at a heightened risk of infection, resulting in several reported deaths among nursing staff. Several preventive measures were adopted to contain the spread of the COVID-19 virus. This study aims to explore the knowledge, attitudes, and practices (KAP) of nurses regarding hand hygiene, mask wearing, and social distancing measures in healthcare settings in Barbados during the COVID-19 pandemic. Method: An online survey of nurses working in public hospitals and polyclinics (public primary care clinics) in Barbados from March 2021 to December 2021 was conducted. A nonsystematic convenience sampling method was employed to recruit nurses who were readily available and willing to participate. A questionnaire captured the sociodemographic information and knowledge and practices related to hand hygiene, the use of face masks, and social distancing. Each correct response received one mark. Overall knowledge scores were categorized as poor (<60%), average (60–80%), or good (>80–100%). Results: Of the 192 participants, the majority were female (82.8%) and had >5 years of experience (82%). The findings revealed that 45.8% had poor knowledge of hand hygiene, and that the knowledge of 43.8% of respondents was average. Multivariable logistic regression showed that, after adjustment for age and gender, registered nurses had 2.1 times increased odds (95% confidence interval 1.0, 4.2) of having good knowledge compared to other nursing categories. Regarding mask wearing, 53.6% of nurses had average knowledge, and 27.1% had good knowledge. Multivariable logistic regression showed that, after adjustment for age and gender, registered nurses had 3.3 times increased odds (95% confidence interval 1.5, 7.4) of having good knowledge compared to nursing assistants. A total of 68.6% of respondents followed the correct steps of handwashing every time, and 98.3% wore a mask in public places. More than half of the nurses (51.2%) kept a safe distance from others to avoid spreading SARS-CoV-2; one-third were in a crowded place(s) in the past three months, and 55.8% usually followed guidelines for social isolation as recommended by the WHO. Conclusions: The study identified knowledge deficiencies related to hand hygiene and wearing masks among nurses. It is imperative to provide additional training on infection control measures.

Measuring Caribbean stress and resilient coping: Psychometric properties of the PSS-10 and BRCS in a multi-country study during the COVID-19 pandemic
Caribbean health research has overwhelmingly employed measures developed elsewhere and rarely includes evaluation of psychometric properties. Established measures are important for research and practice. Particularly, measures of stress and coping are needed. Stressors experienced by Caribbean people are multifactorial, as emerging climate threats interact with existing complex and vulnerable socioeconomic environments. In the early COVID-19 pandemic, our team developed an online survey to assess the well-being of health professions students across university campuses in four Caribbean countries. This survey included the Perceived Stress Scale, 10-item version (PSS-10) and the Brief Resilient Coping Scale (BRCS). The participants were 1,519 health professions students (1,144 females, 372 males). We evaluated the psychometric qualities of the measures, including internal consistency, concurrent validity by correlating both measures, and configural invariance using confirmatory factor analysis (CFA). Both scales had good internal consistency, with omega values of 0.91 for the PSS-10 and 0.81 for the BRCS. CFA suggested a two-factor structure of the PSS-10 and unidimensional structure of the BRCS. These findings support further use of these measures in Caribbean populations. However, the sampling strategy limits generalizability. Further research evaluating these and other measures in the Caribbean is desirable.

Characterizing psychosis-relevant phenomena and cognitive function in a unique population with isolated, chronic and very heavy cannabis exposure
The literature on psychosis-relevant outcomes in cannabis users does not adequately address the confounding effects of other substance use/misuse and psychiatric disorders.
We studied a unique population for whom cannabis use is central and necessary to their way of life. They are forbidden from using other substances, including tobacco and alcohol. Their use of cannabis is heavy, chronic, and begins early. The cases were compared with matched controls who did not use cannabis, alcohol, or drugs. The controls were from the same location and shared similar beliefs and lifestyle, except for cannabis use. Attenuated psychosis-relevant phenomena were assessed with the Schizotypal Personality Questionnaire (SPQ) and cognitive functioning with a culture-neutral computerized cognitive battery.
Fifteen cases and 12 matched controls were studied. The cases averaged >30 000 lifetime cannabis exposures. Relative to controls, the cases had significantly higher mean (s.d.) SPQ scores 24 (14.32) v. 13 (8.92), p = 0.031; and poorer cognitive performance, reflected by a lower mean (s.d.) composite cognitive score -0.23 (0.32) v. +0.28 (0.52), p = 0.03. Moderate to large effect sizes were noted for differences in tests of attention, psychomotor speed, working memory, cognitive flexibility, visuo-spatial processing, and verbal memory. A subsample of cases had higher SPQ scores and worse cognitive performance than their siblings not using cannabis.
Heavy, chronic, and early cannabis use that is not confounded by other drug use is associated with psychosis-relevant phenomena and cognitive deficits. The findings are relevant to the evolving attitudes and laws about cannabis.

Adaptation of WHO COVID-19 guidelines by Caribbean countries and territories
The normative role of the World Health Organization (WHO) involves creating evidence-based, principled guidelines to guide its Member States in making well-informed public health decisions. While these guidelines often need to be adapted to ensure contextual relevance, foster better implementation and adherence, adapting existing guidelines is more efficient than creating new ones. Here we describe the adaptation of the WHO coronavirus disease 2019 (COVID-19) living guideline on pharmacological interventions for the Caribbean using the grading of recommendations, assessment, development and evaluation (GRADE)-ADOLOPMENT method. The Caribbean Public Health Agency and the Pan American Health Organization led the effort, assembling a diverse panel of 16 experts from seven Caribbean countries and territories. The adaptation process, involving 15 steps, was guided by an experienced methodologist and included selecting relevant clinical questions and prioritizing them based on regional needs. The panel evaluated the latest WHO guidelines and integrated additional local data. They adjusted the direction and strength of several recommendations to better fit the Caribbean context, considering local values and preferences, resources, accessibility, feasibility and impact on health equity. Ultimately, we changed the direction of two recommendations and the strength of five, tailoring them to regional realities. This effort highlights the importance of adapting global guidelines to local settings, improving their applicability and effectiveness. The adaptation process also serves as a valuable opportunity for skill transfer and capacity-building in guideline development. Continued research is needed to assess the impact of these adaptations on health-care outcomes in the Caribbean.
