RESUMO
Genes and pathways that allow cells to cope with oncogene-induced stress represent selective cancer therapeutic targets that remain largely undiscovered. In this study, we identify a RhoJ signaling pathway that is a selective therapeutic target for BRAF mutant cells. RhoJ deletion in BRAF mutant melanocytes modulates the expression of the pro-apoptotic protein BAD as well as genes involved in cellular metabolism, impairing nevus formation, cellular transformation, and metastasis. Short-term treatment of nascent melanoma tumors with PAK inhibitors that block RhoJ signaling halts the growth of BRAF mutant melanoma tumors in vivo and induces apoptosis in melanoma cells in vitro via a BAD-dependent mechanism. As up to 50% of BRAF mutant human melanomas express high levels of RhoJ, these studies nominate the RhoJ-BAD signaling network as a therapeutic vulnerability for fledgling BRAF mutant human tumors.

The role of the circadian clock in skin and the identity of genes participating in its chronobiology remain largely unknown, leading us to define the circadian transcriptome of mouse skin at two different stages of the hair cycle, telogen and anagen. The circadian transcriptomes of telogen and anagen skin are largely distinct, with the former dominated by genes involved in cell proliferation and metabolism. The expression of many metabolic genes is antiphasic to cell cycle-related genes, the former peaking during the day and the latter at night. Consistently, accumulation of reactive oxygen species, a byproduct of oxidative phosphorylation, and S-phase are antiphasic to each other in telogen skin. Furthermore, the circadian variation in S-phase is controlled by BMAL1 intrinsic to keratinocytes, because keratinocyte-specific deletion of Bmal1 obliterates time-of-day-dependent synchronicity of cell division in the epidermis leading to a constitutively elevated cell proliferation. In agreement with higher cellular susceptibility to UV-induced DNA damage during S-phase, we found that mice are most sensitive to UVB-induced DNA damage in the epidermis at night. Because in the human epidermis maximum numbers of keratinocytes go through S-phase in the late afternoon, we speculate that in humans the circadian clock imposes regulation of epidermal cell proliferation so that skin is at a particularly vulnerable stage during times of maximum UV exposure, thus contributing to the high incidence of human skin cancers.

BACKGROUND: For cancer patient populations worldwide, the synchronous scale-up of diagnostics and treatments yields meaningful gains in survival and quality of life. Among advanced cancer therapies, radiotherapy (RT) and theranostics are key to achieving practical, high-quality, and personalized precision medicine - targeting disease manifestations of individual patients and broad populations, alike. Aiming to learn from one another across different world regions, the six country vignettes presented here depict both challenges and victories in de novo establishment or improvement of RT and theranostics infrastructure. METHODS: The International Atomic Energy Agency (IAEA) convened global RT and theranostics experts from diverse world regions and contexts to identify relevant challenges and report progress in their own six countries: Belgium, Brazil, Costa Rica, Jordan, Mongolia, and South Africa. These accounts are collated, compared, and contrasted herein. RESULTS: Common challenges persist which could be more strategically assessed and addressed. A quantifiable discrepancy entails personnel. The estimated radiation oncologists (ROs), nuclear medicine physicians (NMPs), and medical physicists (MPs for RT and nuclear medicine) per million inhabitants in the six collective countries respectively range between 2.69-38.00 ROs, 1.00-26.00 NMPs, and 0.30-3.45 MPs (Table 1), reflecting country-to-country inequities which largely match World Bank country-income stratifications. CONCLUSION: Established goals for RT and nuclear medicine advancement worldwide have proven elusive. The pace of progress could be hastened by enhanced approaches such as more sustainably phased implementation; better multinational networking to share lessons learned; routine quality and safety audits; as well as capacity building employing innovative, resource-sparing, cutting-edge technologic approaches. Bodies such as ministries of health, professional societies, and the IAEA shall serve critical roles in convening and coordinating more innovative RT and theranostics translational research, including expanding nuanced global database metrics to inform, reach, and potentiate milestones most meaningfully. POLICY SUMMARY: Aligned with WHO 25×25 NCDs target; WHA70.12 and WHA76.5 resolutions.

Introducción: Se han explorado los posibles predictores no tradicionales de enfermedades cardiovasculares en personas mayores. Objetivo: Identificar los factores de riesgo no tradicionales de mortalidad por enfermedades cardiovasculares en adultos mayores. Métodos: Se realizó un estudio analítico de tipo casos y controles en pacientes adultos mayores pertenecientes a 3 áreas de salud del municipio Santiago de Cuba, durante el año 2021. Los casos fueron pacientes fallecidos por enfermedad cardiovascular de tipo ateroesclerótica y los controles, pacientes adultos mayores vivos, sin la enfermedad. Se determinó la razón de productos cruzados (OR), el intervalo de confianza (IC) y la prueba ji cuadrado para identificar los factores de riesgo que se asociaron a la mortalidad. Resultados: La fragilidad (OR= 3,380; IC: 2,476-4,615; p= 0,000) y el deterioro cognitivo (OR= 2,731; IC: 2,006-3,717; p= 0,000] mostraron asociación estadística muy significativa con la mortalidad; los pacientes con 3 o más factores de riesgo presentaron un mayor riesgo de mortalidad (OR= 4,683). Conclusiones: La fragilidad y la multimorbilidad son nuevos predictores de mortalidad por enfermedades cardiovasculares en adultos mayores, que cuando se asocian, implican mayor riesgo(AU)
Introduction: Possible non-traditional predictors of cardiovascular diseases in older people have been explored. Objective: Identify non-traditional risk factors predictive of mortality from cardiovascular diseases in older adults. Method: An analytical case-control study was carried out on older adult patients belonging to 3 health areas of the Santiago de Cuba municipality, during the year 2021. Cases: patients who died due to atherosclerotic cardiovascular disease, and controls, older adult patients alive, without the disease. The cross-product ratio (OR), the confidence interval (CI) and the chi-square test were determined to identify the factors that were associated with the onset of the disease. Results: Frailty (OR= 3.380; CI: 2.476-4.615; p= 0.000) and cognitive impairment (OR= 2.731; CI: 2.006-3.717; p= 0.000) showed a very significant statistical association with mortality; patients with 3 or more risk factors presented a higher risk of mortality (OR= 4.683). Conclusions: Frailty and multimorbidity are new predictors of mortality from cardiovascular diseases in older adults, which when associated imply greater risk(AU)

Introducción: En el contexto del envejecimiento saludable, la prevención de las enfermedades cardiovasculares es un desafío. Objetivo: Diseñar una escala, basada en factores de riesgo identificados, para la predicción de la mortalidad por afección cardiovascular en ancianos. Métodos: Se realizó un estudio analítico, observacional y retrospectivo, de tipo caso-control, que incluyó a 536 ancianos mayores de 60 años de edad pertenecientes a 3 áreas de salud (policlínicos Ramón López Peña, Municipal y 28 de Septiembre) del municipio de Santiago de Cuba, durante el 2021. La escala se derivó del análisis de regresión logística binaria de los factores de riesgo cardiovascular identificados. Resultados: En la medida que aumentó el puntaje de la escala, se incrementó el porcentaje de pacientes fallecidos. El área bajo la curva fue de 0,836 (p= 0,000) y en la prueba de bondad de ajuste de Hosmer-Lemeshow se obtuvo p= 1,000. Conclusiones: La escala propuesta permitió predecir la mortalidad por afección cardiovascular en adultos mayores, con muy buena capacidad de discriminación y calibración.
Introduction: In the context of healthy aging, the prevention of cardiovascular diseases is a challenge. Objective: To design a scale, based on identified risk factors, for predicting mortality due to cardiovascular affection in elderly. Methods: An analytic, observational and retrospective case-control study was carried out that included 536 elderly over 60 years, belonging to 3 health areas (Ramón López Peña, Municipal and 28 de Septiembre polyclinics) from Santiago de Cuba municipality, during 2021. The scale was derived from the analysis of binary logistical regression of the identified cardiovascular risk factors. Results: As the score of the scale increased, the percentage of dead patients increased. The area under the curve was of 0.836 (p = 0.000) and in the Hosmer-Lemeshow test was obtained p = 1.000. Conclusions: The proposed scale allowed predicting mortality due to cardiovascular affection in elderly, with very good discrimination capacity and calibration.

Using data from the Third National Health and Nutrition Examination Survey (United States, 1988-1994), we compared clinical phenotypes of hepatitis C virus (HCV)-seropositive and seronegative adults aged 20-89 years with hyperglycemia (impaired fasting glucose (IFG) or type 2 diabetes, n=3566 including 86 with HCV). Seroprevalence was higher among younger persons (3.4% for ages 20-59 versus 0.9% for ages 60-89, p=0.002), while traditional correlates of diabetes (hypertension, coronary heart disease) were more prevalent among older persons (both comparisons, p<0.0001). To prevent confounding by age, younger and older persons were analyzed separately. In both age groups, HCV was associated with signs of hepatic impairment and B-cell clonal expansion (higher alanine aminotransferase (ALT) and serum globulin, lower total cholesterol and platelet count). Only among younger persons, however, was HCV also associated with a marker for advanced hepatic fibrosis (elevated serum ferritin) and absence of the classical diabetic phenotype (overweight, coronary heart disease). In addition, among younger persons, HCV was currently associated with family history of diabetes, positively in persons with diabetes and inversely in those with IFG, suggesting that family history of diabetes may serve as a cofactor for progression from HCV-associated IFG to diabetes.

The human epidermal melanocyte is a highly specialized pigmented cell that serves to protect the epidermis from ultraviolet (UV) damage through the production of melanin, or melanogenesis. Misregulation in melanogenesis leading to either hyper- or hypo-pigmentation is found in human diseases such as malasma and vitiligo. Current therapies for these diseases are largely unsuccessful and the need for new therapies is necessary. In order to identify genes and or compounds that can alter melanogenesis, methods are required that can detect changes in pigment production as well as expression of key melanogenesis transcription factors and enzymes. Here we describe methods to detect changes in melanogenesis in a human melanoma cell line, MNT-1, by (1) analyzing pigment production by measuring the absorbance of melanin present by spectrophotometry, (2) analyzing transcript expression of potent regulators of melanogenesis by qunatitative reverse-transcription (RT)PCR and (3) analyzing protein expression of potent regulators of melanogenesis by Western blot (WB).
RESUMO
Para reducir la transmisión del coronavirus, no bastan solo las intervenciones ambientales, sociales y sistémicas, sino es importante actuar sobre el comportamiento de los individuos, factor que favorece la transmisión. Resulta necesario el empleo de mecanismos efectivos de información, educación y comunicación, basados en la alfabetización en salud de forma crítica y con principios básicos de cambios de conducta. Estos enfoques, no aplicados usualmente, van más allá de la simple información y educación sanitarias, pues deben ser llevados a cabo no solo por profesionales de la salud sino por todas las personas influyentes en la población. Se explica el funcionamiento de los principios del cambio de comportamiento, su aplicación en la etapa de enfrentamiento a la COVID - 19 y se muestran algunos enlaces digitales sobre cómo hacer en la alfabetización en salud.
The environmental, social and systemic interventions are not enough to reduce the transmission of coronavirus, but it is important to act on the individuals behavior, a factor that favors the transmission. The use of effective mechanisms of information, education and communication is necessary, based on health literacy in a critical way and with basic principles of behavior changes. These approaches, not usually implemented, go beyond the simple information and health education, because they should be carried out not only by health professionals but also by all the influential people in the population. The functioning of the behavior change principles and their implementation in the COVID - 19 confrontation stage are explained and some digital links on how to proceed in health literacy are shown.

Se priorizaron las revistas internacionales de educación médica y los artículos de los últimos 5 años. Asimismo, se revisó el sitio web de la federación mundial de educación médica. Resultados: La educación médica continua y permanente constituye un principio de la educación médica. Esta transita desde la educación médica continua hasta el desarrollo profesional continuo, y luego al desarrollo profesional continuo basado en competencias y a la educación continua interprofesional. Se muestra la evolución conceptual, y se relaciona la educación médica basada en competencias con el desarrollo profesional continuo. Se mencionan las características de una efectiva educación médica continua y un desarrollo profesional continuo, que pudieran ser aplicables a nuestro contexto. Conclusiones: La necesidad de perfeccionar y mejorar el nuevo modelo económico y social del país ha requerido nuevas resoluciones ministeriales y estatales acerca del desarrollo profesional continuo de los trabajadores y profesionales del país, incluidos los del sector de la salud. Se requiere actualizar los conceptos y las prácticas en este orden para estar a tono con las tendencias internacionales(AU)
Introduction: In the last decade, there has been a conceptual and documental evolution that ranges from continuous medical education and continuous professional development to competence-based professional development. Objective: To review the updated theory about continuous medical education worldwide, its evolution and the possibilities for its improvement in Cuba. Methods: A bibliographic review was carried out in the databases MedLine, PubMed, SciELO, and LILACS, using the descriptors educación médica continua [continuous medical education] and desarrollo profesional continuo [continuous professional development]. We prioritized international medical education journals and articles within the last five years. We also reviewed the website of the World Federation for Medical Education. Results: Continuous and permanent medical education is a principle of medical education. It evolves from continuous medical education to continuous professional development, and then to continuous competence-based professional development and continuous interprofessional education. The conceptual evolution in this area is shown, and competence-based medical education is presented with a focus on its relation with continuous professional development. The characteristics are mentioned corresponding to effective continuous medical education and continuous professional development, which could be applied in our setting. Conclusions: The need to perfect and improve the new economic and social model of the country has required new ministerial and state resolutions concerning continuous professional development of the country's workers and professionals, including those in the health sector. Updating concepts and practices in this respect is required in order to be in tune with international trends(AU)

Two clinical trials have suggested that the combination of vascular endothelial growth factor inhibitor with chemotherapy is associated with venous thromboembolism (VTE). This retrospective cohort study investigates whether a similar association exists when matrix metalloproteinase inhibitor (prinomastat) is combined with chemotherapy. Patients (n=1,023) with stage IIIB, IV, or recurrent non-small cell lung cancer (NSCLC) were followed during 2 randomized, double-blind trials of prinomastat versus placebo orally bid, plus gemcitabine/cisplatin (GC) or paclitaxel/carboplatin (PC). VTE included deep venous thrombosis (DVT) or pulmonary embolism (PE) confirmed by imaging or autopsy. Risks identified in univariate analysis (incidence densities compared by t test) were confirmed in multivariate analysis (proportional hazards model). During 7,500.3 patient-months, 58 VTE (31 PE, 27 isolated DVT) were confirmed in 54 patients. On univariate analysis, VTE was associated with central venous catheter placed within 3 months, 15 mg prinomastat plus GC, and to a lesser extent, 15 mg prinomastat plus PC, baseline performance status, and histologic type. VTE incidence was not increased by 15 mg prinomastat alone (post-discontinuation of chemotherapy), by chemotherapy plus placebo, or by 5 or 10 mg prinomastat plus chemotherapy. On multivariate analysis,VTE hazards (95% confidence interval) were 5.69 (2.61, 12.40) with recently placed central catheter, 2.78 (1.42, 5.43) with 15 mg prinomastat plus GC, and 2.06 (0.98, 4.31) with 15 mg prinomastat plus PC; performance status and histology were nonsignificant. We can conclude that combined treatment with 15 mg prinomastat plus chemotherapy approximately doubles the hazard of VTE among patients with advanced NSCLC.

Leímos con gran satisfacción el artículo Seis décadas de avances y retos para la promoción de la salud en Cuba, publicado en su revista por un colectivo de autoras muy reconocidas por su labor profesional. En este trabajo, como dice su título, se abordan los avances y retos de la promoción de salud (PdS) en nuestro país en las últimas décadas.1 Parte de su valor es la multisectorialidad de sus autoras, lo que permite conocer el trabajo que se realiza en el ámbito de la PdS en escenarios como: salud pública, educación superior, ciencias pedagógicas, cultura física y deporte. Su contenido se distingue por el debate objetivo, poco complaciente, que reconoce algunas de las dificultades que tiene el país para lograr la plena promoción de la salud, según lo establecido por los prerrequisitos descritos en la carta de Ottawa.2 Entre los temas debatidos está la situación de la vivienda y la crisis económica durante la década del 90, por la desaparición del socialismo en países de Europa Oriental.1 Uno de los postulados de la declaración de Curitiba es: la práctica de la promoción de la salud está influenciada directa e indirectamente por la política y por las ideologías.3) Lo que queda implícito en el texto del artículo, que plantea que la promoción de salud es el reflejo del sistema social político y económico. En Cuba se privilegian las conquistas sociales de nuestro sistema (paz, equidad, educación, salud gratuita y accesible para todos, electricidad universal, ecosistema estable, justicia social); predomina el bienestar social, reflejo de una voluntad política que garantiza la igualdad y la satisfacción de las necesidades básicas, en la manera de lo posible. No obstante, no ha sido posible alcanzar la prosperidad total y óptima como consecuencia de amenazas externas como el bloqueo económico norteamericano y algunas debilidades internas como la toma de...(AU)

La prescripción social permite al médico de familia orientar, indicar, prescribir al paciente servicios y ayudas no médicas disponibles en la comunidad, que podrían proporcionarles bienestar y remediar problemas que tradicionalmente se van de la típica solución ofrecida por el profesional de la atención primaria. La prescripción social está relacionada con la prescripción de activos de salud, estilos de vida, intersectorialidad y determinantes sociales de la salud en la localidad que trabaja el médico de familia, y puede ser un componente de un nuevo modelo de salud en la atención primaria. En este trabajo se ofrecen ejemplos de servicios de prescripción social y se sugiere ampliar la lista con facilitadores/pacientes/usuarios en la comunidad(AU)

Objetivo: Realizar una revisión bibliográfica sobre el término abogacía de salud y su relación con la promoción de salud y la medicina familiar. Métodos: Análisis documental de la literatura encontrada en bases de datos y análisis y síntesis de estos documentos desde un enfoque socio-histórico y lógico. Conclusiones: A pesar de que es un tema sugerido para su inclusión en los programas de formación de medicina familiar según los estándares globales de la Organización Mundial de Médicos de Familia y Generales (2013), existen muy escasas referencias en la literatura hispana y latinoamericana de medicina familiar. La abogacía de salud es habitualmente subestimada y obviada como parte de la promoción de salud en medicina familiar, es una actitud, una competencia y una responsabilidad social del médico en general(AU)
