Current status of nuclear cardiology practice in Latin America and the Caribbean, in the era of multimodality cardiac imaging approach: 2022 update.

Cardiovascular diseases (CVDs) are the leading cause of mortality in Latin America and the Caribbean (LAC), with the risk in men being slightly higher than in women. The coronavirus disease 2019 (COVID-19) pandemic caused a significant reduction in the number of cardiac diagnostic procedures globally and in particular in LAC. Nuclear cardiology is available in the region, but there is variability in terms of existing technology, radiopharmaceuticals, and human resources. In the region, there are 2385 single photon emission computed tomography (SPECT) and 315 PET scanners, Argentina and Brazil have the largest number. There is an increasing number of new technologies such as cadmium-zinc-telluride (CZT) cardiac-dedicated gamma cameras, SPECT/computed tomography (CT), and PET/CT. All countries performed myocardial perfusion imaging studies, mainly gated-SPECT; the rest are multi-gated acquisition, mainly for cardiac toxicity; detection of viability; rest gated SPECT in patients with dilated cardiomyopathy, and bone-avid tracer cardiac scintigraphy for transthyretin cardiac amyloidosis diagnosis. Regarding other non-nuclear cardiac imaging modalities, Argentina, Colombia, and Chile have the highest ratio of CT scanners, while Brazil, Argentina, and Chile show the highest ratio of MRI scanners. The development of nuclear cardiology and other advanced imaging modalities is challenged by the high cost of equipment, lack of equipment maintenance and service, insufficient-specific training both for imaging specialists and referring clinicians, and lack of awareness of cardiologists or other referring physicians on the clinical applications of nuclear cardiology. Another important aspect to consider is the necessity of implementing cardiac imaging multimodality training. A joint work of nuclear medicine specialists, radiologists, cardiologists, and clinicians, in general, is mandatory to achieve this goal. National, regional, and international cooperation including support from scientific professional societies such as the American Society of Nuclear Cardiology and Latin American Association of Biology and Nuclear Medicine Societies, cardiological societies, and organizations such as the International Atomic Energy Agency, and Pan American Health Organization, as well as government commitment are key factors in the overall efforts to tackle the burden of cardiovascular diseases in the region.

Improving Oncology-Pathology Collaboration in Resource-Limited Settings: An American Society of Clinical Oncology/College of American Pathologists Initiative.

Accurate pathologic evaluation is essential for proper diagnosis and treatment of patients with cancer. ASCO and the College of American Pathologists have successfully collaborated over the last 15 years to improve collaboration between clinical oncologists and pathologists and to standardize pathologic assay techniques. Cancer is an increasingly recognized societal burden in low- and middle-income countries. In 2015, ASCO and the College of American Pathologists implemented an initiative to identify countries that could benefit from peer insights by jointly convening an international workshop among members of both organizations and pathologists and clinical oncologists from Haiti, Honduras, Vietnam, and Uganda. Honduras was chosen as a pilot site, and representatives of ASCO, the College of American Pathologists, and the Honduras pathology and clinical oncology communities have identified areas in which collaboration might be productive. Multiple barriers, including high poverty levels, poor cancer awareness educational programs, lack of human resources, and delayed diagnosis and treatment, have resulted in a higher cancer mortality rate in Honduras compared with high/moderate-income countries and are shared by other low-income countries. ASCO and the College of American Pathologists member faculty supported a symposium led by Honduras colleagues for interested Honduran pathologists and oncologists. The Honduran communities are now working to establish national resource-appropriate guidelines for both pathology and clinical oncology. Taken together, these efforts indicate that barriers to meet the needs of the clinical oncologists in a low-income country such as Honduras are challenging but not insurmountable.

Consideraciones bioéticas para el trasplante de órganos / Bioethical considerationon organ transplantatio

La implementación deprocedimientos de donación y trasplante de órganos requiere de habilidades médicas y quirúrgicas que han sido ampliamente desarrolladas desde el siglo pasado y que se hanconsolidado en el presente. Sin embargo, se requiere que los países que ven éstos como la oportunidad de prolongar la vida de sus habitantes con enfermedades graves y sin otra opción terapéutica, hagan consideraciones bioéticas que garanticen el respeto a los deberes y derechos propios de la dignidad humana de todos los involucrados, con el fin de evitar violación de derechos humanos universales y garantizar el éxito clínico...(AU)

Occupational risks and injuries in non-agricultural immigrant Latino workers.

BACKGROUND: To investigate occupational health in urban immigrant Latino workers, using a community-based method. METHODS: A survey was administered through consecutively selected door-to-door interviews. RESULTS: Response rate was 80% (n = 427). Average time in the US was 7.6 years, and average job tenure was 2.8 years. Twenty-five reported exposures to over 10 different hazards, and 18% thought these hazards had harmed their health. Only 31% received any job safety training; 55% had no workers' compensation coverage. Of the 47 (11%) with a work injury in the past 3 years, 27% reported difficulty obtaining treatment, 91% lost time from work (median = 13 days) and 29% had to change jobs because of the injury. The annual occupational injury rate was 12.2/100 full-time workers, compared to an expected rate of 7.1. CONCLUSIONS: Urban immigrant workers have increased risk of occupational injuries, with adverse outcomes.
