Background Few studies have described the clinical characteristics of patients with COVID-19 from ethnic minority groups. Our objective was to evaluate the mortality and incidence rates, clinical characteristics and factors associated with mortality in cases with COVID-19 belonging to the Amazonian indigenous ethnic group in Peru. Methods We performed a retrospective cohort study including all cases from COVID-19 among Peruvian people identified as Amazonian indigenous from 07 March to 31 October 2020. We calculated the standardized mortality and incidence ratios using the indirect age-adjusted method to determine the differences between Amazonian Indigenous and the general population. In addition, we used multivariable logistic regression to determine the risk factors for death. Results A total of 19 018 laboratory confirmed COVID-19 cases were analyzed. Indigenous people had 3.18 (95% CI, 3.13–3.23) times the risk of infection and 0.34 (0.31–0.37) times the mortality risk of the general Peruvian population. Males had 1.29 (1.04–1.61) times the odds of death compared with females and for each year of age, the odds of mortality increased 1.03 (1.03–1.04) times. Cases with respiratory distress had 2.47 (1.96–3.10) times more likely to die. Having an immunodeficiency was 18.7 (6.12–57.00) times more likely to die. Discussion The Amazonian indigenous population in Peru was strongly affected by COVID-19 compared with the general Peruvian population.

Recent advances in silicon photonics promise to revolutionize modern technology by improving performance of everyday devices in multiple fields. However, as the industry moves into a mass fabrication phase, the problem of effective testing of integrated silicon photonics devices remains to be solved. A cost-efficient manner that reduces schedule risk needs to involve automated testing of multiple devices that share common characteristics such as input-output coupling mechanisms, but at the same time needs to be generalizable to multiple types of devices and scenarios. In this paper we present a neural network-based automated system designed for in-plane fiber-chip-fiber testing, characterization, and active alignment of silicon photonic devices that use process-design-kit library edge couplers. The presented approach combines state-of-the-art computer vision techniques with time-series analysis, in order to control a testing setup that can process multiple devices and can be easily tuned to incorporate additional hardware. The system can operate at vacuum or atmospheric pressures and maintains stability for fairly long time periods in excess of a month.

A lo largo del proyecto se intentará, a través de un plan de marketing, introducirse dentro del mercado del vino con un nuevo formato de botella. Las botellas de vino que hasta ahora estaban muy estandarizadas, con unas medidas que iban desde las 75 cl, la botella de vino por antonomasia y más demandada, hasta las botellas "magnun" de 4,5 l, tienen copado el mercado. La creación de un nuevo tipo de recipiente y con su adecuada promoción, con su debido plan estratégico, nos hará entrar en el mercado "premiun" del vino, reforzando la marca "Tomás Postigo", lo que en este proyecto se propone es un nuevo formato de embotellado, un nuevo modelo de botella de vino que en un mercado tan atomizado y saturado, como es el del vino, dará un giro en el hábito de consumo de nuestro público objetivo., Grado en Publicidad y Relaciones Públicas

Lobular breast carcinoma represents 2-20% of infiltrative carcinomas of the breast. The incidence of extrahepatic gastrointestinal (GI) tract metastases observed in necropsy studies varies from 6% to 18% and the most commonly affected organ is the stomach, followed by colon and rectum [1-4]. Reported herein is the case of a 67-year-old woman who was primarily diagnosed and surgically treated for a lobular carcinoma of the breast 15 years ago and is now referred with back pain and right hydronephrosis caused by a metastasis in rectum. Frequently, the absence of specific symptoms of digestive metastases of breast cancer leads to a misdiagnosis of this pathology [5-7]. The treatment will be based on a detailed clinical history and histopathological findings. Metastases from breast cancer in GI tract tumours must be excluded in a patient with previous history of breast carcinoma, as in the case reported herein.
