RESUMO

The clinical spectrum of Coronavirus 2019 (COVID-19) includes acute COVID-19, long covid and multisystem inflammatory syndrome in children and adults (MISC/A). The rapid roll-out of COVID-19 vaccination has the potential to affect the clinical presentation of COVID-19 and case reports document rare occurrences of MIS-A after COVID-19 infection and recent vaccination with m-RNA vaccines. We describe 2 cases of MIS-A after COVID-19 infection and recent vaccination with ChAdOx1 nCoV-19.

RESUMO

OBJECTIVES: To assess the status of the HIV epidemic and programmatic implementation in Jamaica while identifying strategies for achieving effective HIV control. METHODS: The assessment included a review of the core indicators of the UNAIDS Global Monitoring Framework, a desk review of program reports, and unstructured interviews of stakeholders. RESULTS: HIV prevalence among adults in Jamaica was 1.5% in 2018 with an estimated 32 617 persons living with HIV (PLHIV) and 27 324 persons (83.8%) diagnosed with HIV; 12 711 (39.0% of all PLHIV or 46.5% aware of their status) were on anti-retroviral therapy (ART) in the public health sector and 61.8% PLHIV on ART were virally suppressed. HIV prevalence among men who have sex with men remains high (31.4% in 2011, 29.6% in 2017) but has declined among female sex workers (12% in 1990, 2% in 2017). HIV prevalence among public sexually transmitted infection clinic attendees, prison inmates and the homeless has increased in recent years. During 2018 approximately 200 000 persons (14% of the population 15-49 years) were tested with 1 165 newly diagnosed PLHIV, indicating that many of the estimated 1 600 newly infected persons in 2018 were unaware of their status. CONCLUSIONS: Critical policy initiatives are needed to reduce barriers to HIV services, ensure young persons have access to condoms and contraceptives, affirm the rights of the marginalized, reduce stigma and discrimination, and introduce pre-exposure prophylaxis. While HIV spread in Jamaica has slowed, the UNAIDS Fast Track goals are lagging. The HIV program must be strengthened to effectively control the epidemic.

RESUMO

Background: COVID-19 vaccination and shielding targeted hypertensive patients in low and middle income countries. We describe the COVID-19 experiences of hypertensive patients in Colombia and Jamaica and discuss factors associated with vaccine acceptance. Methods: A cross-sectional study was conducted between December 2021 and February 2022 in 4 randomly selected primary care clinics in Colombia and 10 primary care clinics in Jamaica. Participants in Colombia were randomly selected from an electronic medical record. In Jamaica consecutive participants were selected on clinic days for non-communicable diseases. Interviewer-administered questionnaires were conducted by telephone. Results: 576 participants were recruited (50% Jamaica; 68.5% female). Jamaica's participants were younger (36% vs 23% <60 years) and had a lower proportion of persons with "more than high school" education (17.2% vs 30.3%, p=0.011). Colombia's participants more commonly tested positive for COVID-19 (24.2% vs 6.3%, p<0.001), had a family member or close friend test positive for COVID-19 (54.5% vs, 21.6%; p<0.001), experienced loss of a family member or friend due to COVID-19 (21.5% vs 7.8%, p<0.001) and had vaccination against COVID-19 (90.6% vs 46.7%, p<0.001). Fear of COVID-19 (AOR 2.71, 95% CI 1.20-6.13) and residence in Colombia (AOR 5.88 (95% CI 2.38-14.56) were associated with COVID-19 vaccination. Disruption in health services affecting prescription of medication or access to doctors was low (<10%) for both countries. Conclusion: Health services disruption was low but COVID-19 experiences such as fear of COVID-19 and vaccine acceptance differed significantly between Colombia and Jamaica. Addressing reasons for these differences are important for future pandemic responses.

RESUMO

This study evaluates a simple clinical audit tool for assessing quality of care and blood pressure control among persons with hypertension in primary care clinics. A systematic random sampling of persons with diabetes mellitus (DM) and hypertension (HTN) attending five health centers in Kingston, Jamaica, was conducted. A modified Ministry of Health paper-based audit tool captured quality of care and outcome indicators (blood pressure and glycemic control). Additional chart audits were conducted by a physician and nurse to assess reliability. One hundred and forty-nine charts were audited between January and September 2017. One hundred and thirty-eight persons (92.6%) had hypertension (27 men and 111 women); 77 persons (51.7%) had DM (14 men and 63 women). The median age was 64 years old. Approximately two-thirds of persons with HTN and DM had electrolytes, lipid profile, and ECG done within the last year. One-fifth of persons with hypertension (18.5% men and 19.8% women, P = 1.000) had adequate blood pressure control with greater control among persons with HTN only compared to persons with both DM and HTN. Poor glycemic control was recorded for 69% of persons with DM (57% men and 71% women, P = .297). Moderate to substantial inter-rater agreement was observed for quality of care indicators. Our findings confirmed that hypertension and glycemic control are inadequate among persons attending primary care clinics in Jamaica's capital city. Simplified clinical audits can provide important quality of care and outcome indicators without losing the meaningfulness of the data collected.

RESUMO

Recently there has been much discussion in the media and literature pertaining to academic misconduct in higher education. Dentistry has not been immune to this discussion. Recent "scandals" involving student misconduct in U.S. dental schools have sparked dialogue within dentistry's premier professional organizations. The authors of this position paper recognize that academic misconduct can be a serious threat to dental education and the profession of dentistry as a whole. This paper addresses academic misconduct in dental school, the impact it may have on our profession, and how educators can begin to develop strategies to curtail cheating in their institutions.

[RESUMEN]. Objetivos. Evaluar el estado de la epidemia de la infección por el VIH en Jamaica y de la ejecución programática, y determinar las estrategias para lograr un control eficaz de la infección por el VIH. Métodos. La evaluación incluyó una revisión de los indicadores básicos del Marco de Vigilancia Mundial del ONUSIDA, un estudio teórico de informes programáticos y entrevistas no estructuradas a los interesados directos. Resultados. La prevalencia de la infección por el VIH en adultos en Jamaica fue del 1,5% en el 2018, con unas 32 617 personas infectadas y unas 27 324 personas (83,8%) con diagnóstico de infección por el VIH; 12 711 personas (39,0% del total de personas con infección por el VIH, o el 46,5% de las que conocían su estado) estaban bajo tratamiento antirretroviral en el sector de salud pública, y el 61,8% de las personas con infección por el VIH que recibieron tratamiento antirretroviral alcanzó la supresión viral. La prevalencia de la infección por el VIH en hombres que tienen relaciones sexuales con hombres sigue siendo alta (31,4% en el 2011, 29,6% en el 2017), aunque ha descendido en las trabajadoras sexuales (12% en 1990, 2% en el 2017). En los últimos años, la prevalencia de la infección por el VIH en personas que acuden a centros públicos de atención de infecciones de transmisión sexual, presidiarios y personas sin hogar ha aumentado. En el 2018, aproximadamente 200 000 personas (14% de la población entre 15 y 49 años) se sometieron a la prueba de VIH, de las cuales 1 165 fueron diagnosticadas como personas recién infectadas por el HIV, lo cual indica que muchas de las 1 600 personas recién infectadas en el 2018 desconocían su estado. Conclusões. Se necesitan iniciativas políticas fundamentales para reducir los obstáculos que impiden el acceso a los servicios de atención de la infección por el VIH, asegurar que las personas jóvenes tengan acceso a preservativos y anticonceptivos, afirmar los derechos de las personas marginadas, reducir la estigmatización y la discriminación, e introducir la profilaxis previa a la exposición. Si bien la propagación de la infección por el VIH se ha desacelerado en Jamaica, el logro de los Objetivos de Respuesta Rápida del ONUSIDA está demorado. Debe fortalecerse el Programa contra el VIH para controlar eficazmente la epidemia.


[RESUMO]. Objetivos. Avaliar a situação da epidemia de HIV e a implementação do Programa Nacional de HIV na Jamaica, identificando estratégias eficazes para controlar o HIV. Métodos. A avaliação incluiu uma revisão dos indicadores-chave da Estrutura de Monitoramento Global do UNAIDS, uma revisão documental dos relatórios do programa e entrevistas não estruturadas com participantes. Resultados. A prevalência de infecção pelo HIV em adultos na Jamaica foi de 1,5% em 2018. Estima-se que haja 32.617 pessoas vivendo com o HIV (PVHIV), das quais 27.324 (83,8%) foram diagnosticadas; 12.711 (39,0% de todas as PVHIV, e 46,5% das que conhecem seu diagnóstico) estavam em terapia antirretroviral (TAR) no setor da saúde pública, e 61,8% das PVHIV em ART alcançaram a supressão viral. A prevalência de HIV entre homens que fazem sexo com homens continua alta (31,4% em 2011, 29,6% em 2017), mas diminuiu entre mulheres profissionais do sexo (12% em 1990, 2% em 2017). A prevalência de HIV entre os pacientes que frequentam clínicas públicas de atenção a infecções sexualmente transmissíveis, presidiários e desabrigados tem aumentado nos últimos anos. No ano de 2018, aproximadamente 200.000 pessoas (14% da população de 15 a 49 anos) foram testadas, sendo feitos 1.165 novos diagnósticos de infecção pelo HIV, o que indica que muitas das 1.600 pessoas recém-infectadas estimadas em 2018 não estavam cientes de sua infecção. Conclusões. São necessárias iniciativas políticas essenciais para reduzir as barreiras no acesso aos serviços de HIV, assegurar que os jovens tenham acesso a preservativos e métodos contraceptivos, afirmar os direitos dos marginalizados, reduzir o estigma e a discriminação e introduzir a profilaxia pré-exposição. Embora a propagação do HIV na Jamaica tenha perdido velocidade, o progresso para alcançar as metas da estratégia Fast Track do UNAIDS tem sido lento. Para controlar a epidemia de forma eficaz, é preciso fortalecer o Programa Nacional de HIV.

RESUMO

To estimate the association between a simple measure of sexual partner concurrency and sexually transmitted infection (STI) we conducted a cross-sectional population-based household survey (n = 1795) and targeted surveys of people at venues where people meet sexual partners (n = 1580) to ask about sexual behaviour. Persons interviewed at venues were tested for HIV, gonorrhoea, chlamydia, and trichomoniasis. We compared the association between STI and reporting a partner had other partners. More women than men reported their main partner had other partners. Thirteen percent of all women in the population-based survey and 14.4% in the targeted survey reported having one partner in the past 12 months and that partner had additional partners. STI prevalence was significantly associated with reporting a partner had other partners (36.8% vs. 30.2%; prevalence ratio [PR] 1.2; 95% confidence interval [CI] 1.1, 1.4). Construction of complete sexual networks is costly and not routinely feasible. We recommend adding a question to cross-sectional surveys used to monitor sexual behaviour about whether the respondent believes his or her partner has other sexual partners. Although subject to bias, the question was useful in Jamaica to identify a group of women with only one sexual partner at increased risk of infection.

RESUMO

PURPOSE: The present material reports on prosthodontic complications in a trial of 51 patients with prostheses supported by single-stage implants over a period of 36 months. MATERIALS AND METHODS: One hundred eighty-six single-stage implants were placed in 51 patients over a 3-year period in 2 carefully controlled prospective clinical trials. Nineteen of the patients (103 implants) were completely edentulous and restored with a maxillary complete denture and a mandibular fixed-detachable complete prosthesis. Single metal-ceramic crowns or fixed partial dentures were fabricated for the remaining 32 patients (83 implants). The fixed restorations were either screw-retained or cemented. RESULTS: All patients/implants were followed for a minimum of 3 years. Complications in the edentulous patients included fracture of denture teeth, fracture of the maxillary denture, and occlusal screw loosening. Occlusal screw loosening and loss of the resin composite access plug were the only complications observed in the patients treated with screw-retained restorations. No complications were found in the patients restored with cemented restorations on solid abutments. DISCUSSION: Problems with prostheses were very common in the completely edentulous patients (13 of 19 patients encountered complications), possibly a result of increased bite force or inadequate laboratory technique. Tooth fractures were seen more frequently in men than in women. Complications occurred in only 5 of the 32 partially edentulous patients. CONCLUSION: Complications were associated with laboratory-related procedures rather than the implant system itself.

RESUMO

BACKGROUND: This study evaluated the clinical performance of 39 light and heat polymerized fixed partial bridges made with a substructure of preimpregnated, unidirectional fiber-reinforced composite, or FRC, veneered with a hybrid particu late composite. METHODS: The authors evaluated 22 extracoronal, full-coverage retainer prostheses and 17 intracoronal, partial-coverage retainer prostheses placed over a 37-month period. All substructures initially were fabricated with a low-volume FRC. The authors reevaluated this design after early failures occurred, leading to a substructure with a higher volume of FRC. All prostheses were assessed for surface integrity, anatomical contour, marginal integrity and structural integrity at several intervals. RESULTS: The data show that survival was associated primarily with substructure design volume. When patients with severe parafunctional habits were excluded, the survival rate was 95 percent for prostheses made with a high-volume substructure (survival range, 2.77 to 4.30 years; mean +/- standard deviation survival, 3.75 +/- 0.4 years). Retainer configuration did not have a statistically significant influence on clinical survival. For all surviving prostheses, the authors observed few changes in any clinical parameters from baseline to 48 months. A loss of surface luster was observed in the majority of cases. Repairable surface defects were detected on two prostheses at 24 months. Scanning electron microscopic analyses indicated no exposed fibers on the occlusal surface and minimal wear. CONCLUSIONS: This study shows that a unidirectional, preimpregnated FRC can be used successfully to make bridges of variable retainer designs that last up to four or more years when a high-volume substructure is used. CLINICAL IMPLICATIONS: Short-span polymer prostheses made with particulate composite and unidirectional glass FRC can be used in certain clinical situations in which a metal substructure is not desired.

RESUMO

Complete denture fabrication can be an enjoyable and profitable facet of a dental practice. The key to success is a thorough diagnosis, understanding the patient's desires and expectations, and following a standardized sequence of treatment. This article describes a modified complete denture technique designed to minimize chair time but maintain sound principles of denture construction.

RESUMO

The use of fiber composite technology in the creation of metal-free implant prostheses may solve many of the problems associated with a metal alloy substructure such as corrosion, toxicity, complexity of fabrication, high cost, and esthetic limitations. Laboratory and clinical research evaluating glass fiber-reinforced composite prostheses used to restore and replace teeth has shown that these materials exhibit excellent mechanical properties and can form a chemical bond to resin-based veneer materials such as those used in the fabrication of certain types of implant prostheses. Two different designs of fiber-reinforced composite implant prostheses have been developed and placed in human subjects. One design (screw-retained, retrievable prosthesis) is used with implant abutments that allow for screw-retained prostheses; the other design is used with abutments that retain prostheses with a luting material. Both designs are described in this article. The prostheses have functioned well in a small group of preliminary subjects, but clinical trials with larger subject populations are needed to more completely evaluate the potential of fiber-reinforced composites in implant prosthodontics.
