RESUMEN
The molecular technology known as clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) is revolutionizing the field of medical research and deepening our understanding of numerous biological processes. The attraction of CRISPR/Cas9 lies in its ability to efficiently edit DNA or modulate gene expression in living eukaryotic cells and organisms, a technology that was once considered either too expensive or scientifically risky. CRISPR/Cas9 has been successfully applied in agriculture to develop the next generation of disease-resistant plants. Now, the capability of gene editing has been translated to the biomedical area, focusing on the future of medicine faced with drug-resistant microbes by selectively targeting genes involved in antibiotic resistance, for example, or finding the ultimate strategy for cancer or HIV. In this regard, it was recently demonstrated that an injection of cancer-fighting CRISPR-modified white blood cells in a patient suffering from metastatic lung cancer could lead to promising results. Researchers and bioethicists are debating questions about the regulation of CRISPR/Cas9 that must be addressed. While legal challenges surround the use of this technique for genetically modifying cell lines in humans, we review the basic understanding of CRISPR/Cas9 and discuss how this technology could represent a candidate for treatment of non-communicable diseases in nutrition, such as obesity.

Objetivo. Comparar la salud, uso de servicios sanitarios y necesidad insatisfecha de atención médica (NIAM) entre inmigrantes y nativos del sureste español. Material y métodos. Estudio transversal de dos muestras representativas de población: inmigrante (n=1150) y nativa (n=1303; Encuesta Nacional de Salud). Se creó una única base de datos con ponderación específica para cada muestra y se estimaron razones de prevalencia (RP) mediante regresión multivariante. Resultados. Marroquíes, ecuatorianos y europeos del este (EE) declararon peor salud que los nativos (RPs [IC95%]: 2.45 [1.91-3.15]; 1.51 [1.28-1.79] y 1.44 [1.08-1.93], respectivamente). Los inmigrantes hicieron mayor uso de las urgencias (excepto EE) y consumieron menos fármacos. Los marroquíes mostraron la mayor diferencia en la frecuencia de NIAM (RP [IC95%]: 12.20 [5.25-28.37]), principalmente por razones laborales (46%). Conclusiones. La salud y el uso de servicios sanitarios difirieron significativamente entre inmigrantes y nativos. Destaca la NIAM alta en marroquíes por causa laboral.
Objective. To compare the self-perceived health, use of health services and unmet need for health care (UNHC) among immigrants and native populations of Southeast Spain. Materials and methods. Cross-sectional study of two representative samples of 1150 immigrants, and 1303 native participants from the National Health Survey. A single database was created with specific weights for each sample, and prevalence ratios (PR) were estimated by multivariate regression. Results. Moroccans, Ecuadorians and Eastern Europeans (EE) reported poorer health than the native population (PRs [CI95%]: 2.45 [1.91-3.15]; 1.51 [1.28-1.79] and 1.44 [1.08-1.93], respectively). Immigrants made greater use of emergencies that natives (except for EE) and had lower use of medication. Moroccan showed the greatest difference in the frequency of UNHC (PR [CI95%]:12.20 [5.25 - 28.37]), mainly because of working limitations (46%). Conclusions. The health status and use of health services among immigrants differ significantly from those of natives. Results highlight the higher frequency of UNHC among immigrants, especially high in Moroccans.
