RESUMO

Positive Plus One is a mixed-methods study of long-term mixed HIV-serostatus relationships in Canada (2016-19). Qualitative interviews with 51 participants (10 women, 41 men, including 27 HIV-positive and 24 HIV-negative partners) were analyzed using inductive thematic analysis to examine notions of relationship resilience in the context of emerging HIV social campaigns. Relationship resilience meant finding ways to build and enact life as a normal couple, that is, a couple not noticeably affected by HIV, linked to the partner with HIV maintaining viral suppression and achieving "undetectable = untransmittable" (U = U). Regardless of serostatus, participants with material resources, social networks, and specialized care were better able to construct resilience for HIV-related challenges within their relationships. Compared to heterosexual couples and those facing socioeconomic adversity, gay and bisexual couples were easier able to disclose, and access capital, networks and resources supporting resilience. We conclude that important pathways of constructing, shaping, and maintaining resilience were influenced by the timing of HIV diagnosis in the relationship, access to HIV-related information and services, disclosure, stigma and social acceptance.

RESUMO

INTRODUCTION: Substance-related acute toxicity deaths continue to be a serious public health concern in Canada. This study explored coroner and medical examiner (C/ME)perspectives of contextual risk factors and characteristics associated with deaths from acute toxic effects of opioids and other illegal substances in Canada. METHODS: In-depth interviews were conducted with 36 C/MEs in eight provinces and territories between December 2017 and February 2018. Interview audio recordings were transcribed and coded for key themes using thematic analysis. RESULTS: Four themes described the perspectives of C/MEs: (1) Who is experiencing a substance-related acute toxicity death?; (2) Who is present at the time of death?; (3) Why are people experiencing an acute toxicity death?; (4) What are the social contextual factors contributing to deaths? Deaths crossed demographic and socioeconomic groups and included people who used substances on occasion, chronically, or for the first time. Using alone presents risk, while using in the presence of others can also contribute to risk if others are unable or unprepared to respond. People who died from a substance-related acute toxicity often had one or more contextual risk factors: contaminated substances, history of substance use, history of chronic pain and decreased tolerance. Social contextual factors contributing to deaths included diagnosed or undiagnosed mental illness, stigma, lack of support and lack of follow-up from health care. CONCLUSION: Findings revealed contextual factors and characteristics associated with substance-related acute toxicity deaths that contribute to a better understanding of the circumstances surrounding these deaths across Canada and that can inform targeted prevention and intervention efforts.

RESUMO

BACKGROUND: With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies. METHODS: PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners. RESULTS: We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner. CONCLUSIONS: Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of "happy couple" bias.

RESUMO

As people living with HIV are living longer lives, they have a correspondingly greater opportunity to enjoy long-term romantic and sexual partnerships, including with persons who do not live with HIV ("serodiscordant" relationships). In these dyads, asymmetries may emerge in access to social resources between partners. In this paper we examined how serodiscordant couples access informal (interpersonal, such as family and friends) and formal (practitioner, such as doctor or social worker) social resources for health. We recruited 540 participants in current serodiscordant relationships, working with 150 AIDS service organizations and HIV clinics across Canada from 2016 to 2018. Our findings demonstrate that partners with HIV have greater access to formal resources than their partners (through health care professionals, therapists/counselors/support workers), while both persons have similar access to resources through informal social relationships (family and friends). Furthermore, the findings indicated that HIV positive partners accessed more varied forms of support through formal ties, compared to HIV negative persons. We offer recommendations for changes to how HIV-negative partners in a serodiscordant relationship are served and cared for, and particularly, the importance of moving toward dyad-focused policies and practices.

RESUMO

The Caribbean region is lacking an assessment of the antibody response and side effects experienced after AstraZeneca COVID-19 vaccination (AZD1222). We examined severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike receptor-binding domain (RBD) IgG levels and report the side effects noted in a Jamaican population after AZD1222 vaccination. Median RBD IgG levels for persons without evidence of previous SARS-CoV-2 infection were 43.1 binding international units (bIU)/mL 3 to 7 weeks after the first dose, increasing to 100.1 bIU/mL 3 to 7 weeks after the second dose, and decreasing to 46.9 bIU/mL 16 to 22 weeks after the second dose. The median RBD IgG level 2 to 8 weeks after symptom onset for unvaccinated SARS-CoV-2-infected persons of all disease severities was 411.6 bIU/mL. Common AZD1222 side effects after the first dose were injection site pain, headache, and chills. Most people reported no side effects after the second dose. AZD1222 is widely used across the English-speaking Caribbean, and our study provides evidence for its continued safe and effective use in vaccination programs.

RESUMO

BACKGROUND: The performance of the Roche Elecsys® Anti-SARS-CoV-2, Abbott Architect SARS-CoV-2 IgM, Abbott Architect SARS-CoV-2 IgG, Euroimmun SARS-CoV-2 IgA, Euroimmun SARS-CoV-2 IgG ELISA, and Trillium IgG/IgM rapid assays was evaluated in Jamaica. METHODS: Diagnostic sensitivities of the assays were assessed by testing serum samples from SARS-CoV-2 PCR-confirmed persons and diagnostic specificity was assessed by testing serum samples collected during 2018-2019 from healthy persons and from persons with antibodies to a wide range of viral infections. RESULTS: Serum samples collected ≥14 days after onset of symptoms, or an initial SARS-CoV-2 RT-PCR positive test for asymptomatics, showed diagnostic sensitivities ranging from 67.9 to 75.0% when including all possible disease severities and increased to 90.0-95.0% when examining those with moderate to critical disease. Grouping moderate to critical disease showed a significant association with a SARS-CoV-2 antibody positive result for all assays. Diagnostic specificity ranged from 96.7 to 100.0%. For all assays examined, SARS-CoV-2 real-time PCR cycle threshold (Ct) values of the initial nasopharyngeal swab sample testing positive were significantly different for samples testing antibody positive versus negative. CONCLUSIONS: These data from a predominantly African descent Caribbean population show comparable diagnostic sensitivities and specificities for all testing platforms assessed and limited utility of these tests for persons with asymptomatic and mild infections.

RESUMO

AIM: Human papillomavirus (HPV) has been reported to be associated with oral and oropharyngeal cancer. However, little information is available about the epidemiology of oral HPV infection in Jamaica. The purpose of the present study was to assess the prevalence of oral HPV strains using the oral rinse method in HIV and non-HIV Jamaican patients, as well as to determine the association of HPV with sexual practices, smoking, and alcohol use. METHODS: A cross-sectional study was conducted on patients attending The University of the West Indies Mona Dental Polyclinic and the Centre for HIV/AIDS Research and Education Services. Salivary samples were tested through molecular analysis for 37 HPV genotypes using the linear array HPV genotyping test. A survey questionnaire was used to obtain demographic details, smoking history, alcohol practice, sexual practice, and history of HPV testing. RESULTS: The HPV prevalence was 8.65% in 18-64 y olds (N = 104), with a slight female predilection (55%). No high-risk HPV types were found. HPV-84 was the most common type in both HIV and non-HIV patients; 66.7% of HPV-positive participants reported that they had six or more lifetime sexual partners. CONCLUSION: The prevalence of oral HPV was similar to that in other countries. No statistically-significant relationship was observed between the prevalence of HPV and either the number of sexual partners, smoking, or alcohol history. A nationwide study on oral HPV detection might be helpful in developing a HPV vaccination policy in Jamaica.

RESUMO

Background: Antibiotic resistance (ABR) is a serious threat that requires coordinated global intervention to prevent its spread. There is limited data from the English-speaking Caribbean. Methods: As part of a national programme to address antibiotic resistance in Jamaica, a survey of the knowledge, attitudes and antibiotic prescribing practices of Jamaican physicians was conducted using a 32-item self-administered questionnaire. Results: Of the eight hundred physicians targeted, 87% responded. The majority thought the problem of resistance very important globally (82%), less nationally (73%) and even less (53%) in personal practices. Hospital physicians were more likely to consider antibiotic resistance important in their practice compared to those in outpatient practice or both (p < 0.001). Composite knowledge scores were generated and considered good if scored > 80%, average if 60-79% and poor if < 60%. Most had good knowledge of factors preventing resistance (83%) and resistance inducing potential of specific antibiotics (59%), but only average knowledge of factors contributing to resistance (57%). Knowledge of preventative factors was highest in females (p = 0.004), those with postgraduate training (p = 0.001) and those > four years post graduation (p = 0.03). Empiric therapy was often directed by international guidelines and cultures were not routinely done. Limited laboratory and human resources were identified as challenges. Conclusion: Physicians in this study were aware of the problem of ABR, but downplayed its significance nationally and personally. These results will guide a national antibiotic stewardship programme.

RESUMO

ABSTRACT Objective The HIV cascade of care describes the spectrum of engagement in HIV care from diagnosis to viral suppression (VS). The study objective was to develop a baseline HIV cascade of care for new HIV diagnoses in the Bahamas in 2014. Methods Individuals who were newly diagnosed with HIV in 2014 and known to be alive within a year of that diagnosis were included in the cascade of care (n = 250). Individuals with one CD4 or HIV viral load (VL) measure in 2014 were considered linked to care. Those with at least two CD4 counts in the year were considered retained in care. Eligibility for antiretroviral therapy (ART) was based on having a CD4 count < 350 cells/mm3. ART adherence was defined as filled prescriptions > 11 months/year. VL < 1 000 copies/ml was considered suppressed. Comparisons were made in the cascades by gender and age. Results Of the 250 persons in the study, 79 of them (32%) were retained in care. Antiretrovirals (ARVs) were prescribed to 116 of the 250 (46%); of those 116, 48 of them (41%) achieved VS. A higher proportion of women achieved VS than did men, but this difference did not reach statistical significance. Similarly, there were differences in VS based on age, but the differences were not statistically significant. Conclusions In the Bahamas, increased efforts are needed to help people living with HIV to link to and be retained in care. VS may remain suboptimal unless ART is scaled up and adherence interventions are included in measures to improve the treatment cascade.


RESUMEN Objetivo El proceso continuo de la atención de la infección por el VIH describe el espectro de intervenciones en la atención de la infección, desde el diagnóstico hasta la supresión viral. El objetivo del estudio fue elaborar un proceso continuo de la atención como punto de referencia y comparación para nuevos diagnósticos de infección por el VIH en las Bahamas en el 2014. Métodos En el proceso continuo de la atención se incluyó a personas con diagnóstico de infección por el VIH en el 2014 y que continuaban vivas a un año del diagnóstico (n = 250). Se consideró vinculadas a la atención a aquellas personas con un recuento de linfocitos CD4 o una medición de la carga viral de VIH en el 2014. Aquellas con al menos dos recuentos de CD4 en el año se consideraron retenidas en la atención. La aptitud para el tratamiento antirretroviral se basó en tener un recuento de CD4 < 350 células/mm3. Se definió adherencia al tratamiento antirretroviral como la entrega de la prescripción >11 meses/año. Se consideró supresión viral a una carga viral de < 1 000 copias/ml. Se hicieron comparaciones en las cascadas por sexo y edad. Resultados De las 250 personas que participaron en el estudio, 79 (32%) se retuvieron en la atención. Se prescribieron antirretrovirales a 116 de las 250 personas (46%); de estas 116 personas, 48 (41%) lograron la supresión viral. Las mujeres lograron la supresión viral en una proporción mayor que los hombres, pero esta diferencia no fue estadísticamente significativa. Igualmente, se observaron diferencias en la supresión viral según la edad, pero estas tampoco fueron estadísticamente significativas. Conclusiones En las Bahamas, es necesario incrementar los esfuerzos para ayudar a las personas con infección por el VIH a vincularse y mantenerse en la atención. La supresión viral puede permanecer en niveles subóptimos a menos que se amplíe el tratamiento antirretroviral y se incluyan intervenciones de adherencia terapéutica en las medidas para mejorar el proceso continuo de la atención.

RESUMO

PURPOSE: The purpose of this clinical nurse specialist-led interprofessional quality improvement project was to reduce hospital-acquired pressure ulcers (HAPUs) using evidence-based practice. BACKGROUND: Hospital-acquired pressure ulcers (PUs) have been linked to morbidity, poor quality of life, and increasing costs. Pressure ulcer prevention and management remain a challenge for interprofessional teams in acute care settings. RATIONALE: Hospital-acquired PU rate is a critical nursing quality indicator for healthcare organizations and ties directly with Mount Sinai Hospital's (MSH's) mission and vision, which mandates providing the highest quality care to patients and families. DESCRIPTION: This quality improvement project, guided by the Donabedian model, was based on the Registered Nurses' Association of Ontario Best Practice Guideline Risk Assessment & Prevention of Pressure Ulcers. A working group was established to promote evidence-based practice for PU prevention. Initiatives such as documentation standardization, development of staff education and patient and family educational resources, initiation of a hospital-wide inventory for support surfaces, and procurement of equipment were implemented to improve PU prevention and management across the organization. OUTCOME: An 80% decrease in HAPUs has been achieved since the implementation of best practices by the Best Practice Guideline Pressure Ulcer working group. CONCLUSION: The implementation of PU prevention strategies led to a reduction in HAPU rates. The working group will continue to work on building interprofessional awareness and collaboration in order to prevent HAPUs and promote an organizational culture that supports staff development, teamwork and communication. IMPLICATIONS: This quality improvement project is a successful example of an interprofessional clinical nurse specialist-led initiative that impacts patient/family and organization outcomes through the identification and implementation of evidence-based nursing practice.

RESUMO

BACKGROUND: The gastrointestinal tract is a common site of involvement in HIV-infected patients. Gastrointestinal symptoms are common in the general population and are associated with decreased quality of life. METHODS: Ambulatory consecutive HIV-infected patients and consecutive healthy blood donors seen in Jamaica were studied. A 19-item questionnaire of GI symptoms was administered. RESULTS: There were 196 respondents. Among 99 HIV patients, the mean number of symptoms was 2.9 and in 97 controls 3.3 (p=0.091). Dysphagia and odynophagia were present in 8.1% of HIV patients and 3.1% of the controls (p=0.129). Belching was present in 59.6% of HIV patients and in 96.8% of controls (p≤0.001). In the control group, 44.3% had heartburn compared to 29.3% of HIV patients. Within the preceding year, 26.3% of HIV participants and 12.4% of controls sought medical attention for their GI symptoms (p=0.001). GI symptomatology was directly related to immune status in the HIV group as patients with a CD4 count of less than 200 cells/µL reported up to 6 GI symptoms, those with CD4 of 201-350 cells/µL had 3 symptoms, and patients with CD4 greater than 351 cells/µL had 1 symptom. Pain on swallowing, and vomiting were significantly more common in patients with CD4 <350 cells/µL than in controls. CONCLUSIONS: GI symptoms were common in HIV patients and controls. In HIV patients symptoms were directly related to CD4 count. Pain on swallowing and vomiting were significantly more common in patients with CD4 <350 cells/µL than in controls.
