RESUMO
Discovering novel means of protection from harmful substances in toothpaste is essential due to its mass production, and frequent exposure to its ingredients by consumers. This method of safeguarding through discovery demonstrates toothpaste safety, which is at risk of being stifled by other commercial priorities. Among the ingredients in toothpaste that cause adverse effects is sodium lauryl sulphate (SLS). An understanding of this source and its effects therefore allows for investigating preventative strategies through the use of safer alternatives. Saponin, a naturally occurring chemical in several plant species was discovered to be an alternative compound that may parallel the effects of sodium lauryl sulphate, yet exude less ill effects. This article highlights the benefits of saponin and its presence in a heavily consumed and exported fruit in Jamaica (ackee, Blighia sapida). The possibility of extracting saponin from ackee, and its use in the toothpaste industry as an alternative to sodium lauryl sulphate are discussed. Through consideration of this alternative, the potential exists to improve the safety of toothpastes and consequently improve oral health.

OBJECTIVE: To investigate the association of whole-blood fatty acids and reported intakes of fats with risk of prostate cancer (PCa). DESIGN: Case-control study of 209 men 40-80 years old with newly diagnosed, histologically confirmed prostate cancer and 226 cancer-free men attending the same urology clinics. Whole-blood fatty acid composition (mol%) was measured by gas chromatography and diet assessed by food frequency questionnaire. RESULTS: High whole-blood oleic acid composition (tertile 3 vs. tertile 1: OR, 0.37; CI, 0.14-0.0.98) and moderate palmitic acid proportions (tertile 2: OR, 0.29; CI, 0.12-0.70) (tertile 3: OR, 0.53; CI, 0.19-1.54) were inversely related to risk of PCa, whereas men with high linolenic acid proportions were at increased likelihood of PCa (tertile 3 vs. tertile 1: OR, 2.06; 1.29-3.27). Blood myristic, stearic and palmitoleic acids were not associated with PCa. Higher intakes of dietary MUFA were inversely related to prostate cancer (tertile 3 vs. tertile 1: OR, 0.39; CI 0.16-0.92). The principal source of dietary MUFA was avocado intake. Dietary intakes of other fats were not associated with PCa. CONCLUSIONS: Whole-blood and dietary MUFA reduced the risk of prostate cancer. The association may be related to avocado intakes. High blood linolenic acid was directly related to prostate cancer. These associations warrant further investigation.

We investigated the associations between body size and risk of prostate cancer in a hospital-based case-control study in Jamaica. Height, weight, waist, and hip circumference were measured at enrollment, and data collected on medical and lifestyle factors for newly diagnosed cases (n = 243) and controls (n = 275). Compared with men in the normal range of waist-hip ratio (WHR), men with WHR > or =0.95 were at greater risk of total prostate cancer (OR,1.72; CI, 1.01-3.00) and high-grade cancer (OR, 2.02; CI, 1.03-3.96). With additional control for BMI, the association with WHR remained significant for total prostate cancer (OR, 1.90; CI, 1.01-3.53) and high-grade disease (OR, 2.94; CI, 1.34-6.38). There was no association between waist circumference and cancer without control for BMI but after controlling for BMI, waist circumference >90 cm (OR, 2.45; CI, 1.01-5.94) and >102 cm (OR, 5.57; CI, 1.43-18.63) showed a dose-response relationship with high-grade disease. Height and BMI were not associated with risk of prostate cancer. Abdominal obesity may be associated with risk of high-grade prostate cancer. Risk may be greater in those with higher abdominal obesity relative to overall size. The results further highlight the importance of investigating relationships by characteristics of the tumor.

OBJECTIVE: To assess trends in the use of private and public health care services among Jamaicans over a 15-year period (1991-2007). DESIGN AND METHODS: Statistics on the use of health care services were taken from the Jamaica Survey of Living Conditions (JSLC) for the 15-year period 1993 to 2007. Use of hospital services were represented in income quintiles and compared for private and public facilities. The difference in percentage use between public and private was compared by quintiles over the period and the variability in those differentials assessed. RESULTS: This study highlights the increasing use of private services by increasing wealth, exaggerated for the wealthiest quintile. There is a widening of the differences in utilization between public and private centers as income level increases (P < 0.001). CONCLUSIONS: Internal and external economic conditions influence the use of private and public health care services in Jamaica. Although the relative increase in the cost (to the user) of public health care is more than that for private health care, the actual cost to use the public health care system is still significantly cheaper than using the private system. Lower income health care users tend to take the lesser cost option.
RESUMO
BACKGROUND: This short biographical piece provides a brief description of the experience of a medical teacher at the University of the West Indies in Jamaica. It traces his initial response to being chosen as a teacher and shows movement from self-doubt to assertive thinking about the role of the teacher. The development of the teacher, though buttressed by a formal training intervention, is couched within a sensitive understanding of the whole student.

Al igual que el resto del mundo, el Caribe ha sido testigo del drástico paso de las enfermedades nutricionales y transmisibles a las enfermedades no transmisibles y crónicas. No obstante, en el Caribe este cambio ha coincidido con una nueva dinámica, creada por la emergencia de enfermedades transmisibles -como la infección por el VIH/sida- junto con los problemas relacionados con el envejecimiento, las enfermedades cardiovasculares, la violencia y las lesiones, entre otros. En este artículo se hace una revisión de la historia de la atención sanitaria en el Caribe, los retos y enfoques del sector salud y la nueva orientación en la atención primaria de salud (APS). Las observaciones se basan en trabajos publicados. En el Caribe, la Declaración de Alma-Ata sirvió como importante punto de giro y ofreció orientación, apoyo y dirección a medida que los países perfilaban sus servicios de salud para satisfacer sus necesidades. La creatividad y el ingenio surgieron como rasgos distintivos del enfoque caribeño en la reestructuración de la APS, ante los retos económicos, sociales, culturales, de recursos humanos y de políticas que enfrentaban. El fortalecimiento de de la capacidad institucional, la extensión de los programas sociales, los esquemas nacionales de seguros de salud, los programas específicos de promoción de salud y la ampliación de la investigación en apoyo al desarrollo de políticas continúan evidenciando el esfuerzo caribeño para responder a los cruciales retos epidemiológicos. A pesar de esos retos, se han establecido alianzas dentro y fuera del Caribe. Además, la Carta del Caribe para la Promoción de la Salud ha servido como elemento crítico para el desarrollo de la APS.

Primary health care (PHC) is defined as "essential health care based on practical, scientifically sound, and socially acceptable methods and technology made universally accessible to individuals and families in the community through their full participation and at a cost that the community and country can afford to maintain at every stage of their development in the spirit of self-reliance and self-determination." For the effective delivery of PHC to occur, it must be undergirded by a national health system infrastructure that has five key components: (1) development of health resources, such as manpower, facilities, equipment and supplies; (2) organized arrangement of health resources through the establishment of national health authorities, the provision of national health insurance, and the integration of public and private health services; (3) delivery of health care through the media of primary, secondary and tertiary health services; (4) economic support through sources, such as public financing and foreign aid; and (5) management through strong leadership, policy formulation, regulation and monitoring and evaluation (AU)
