This article deals with a project developed pursuing two parallel subjects: one, the analysis of production processes in small and micro enterprises (Pymes) that make stainless steel domestic goods, and two, the design and manufacturing of prototype products. A characteristic of the pymes sector is that their processes are based on plastic misshaping, thus obtaining middle?quality products, revolution geometric shapes, and little complexity; this is eminently a handmade process.

Tomando en cuenta nuestras altas cifras de morbimortalidad por esta patología a nivel nacional superiores a las de otros países de la región, sugerimos que nuestras autoridades y gestores de salud sigan desarrollando estrategias a nivel nacional para mejorar el proceso de atención del infarto de miocardio con elevación del segmento ST, implementando un sistema de redes para la atención del infarto, fortaleciendo la estrategia farmacoinvasiva oportuna en centros periféricos sin capacidad de ICP, y mejorando la capacidad de ICP primaria en los principales hospitales de nuestro país.

Pancreatic hamartomas (PH) are extremely unusual non-neoplastic tumor-like lesions and accounts for <1% of all hamartomas. Moreover, there is a distinct variant of PH denominated Pancreatic lipomatous hamartoma (PLH), that is even rarer, with only 5 cases, including the present case, reported in the literature. PLH lacks well-defined features and clinically can be mistaken with other lipomatous lesions of the pancreas, including lipoma, pancreatic lipomatosis, PEComa, liposarcoma, and malignant tumors with lipomatous components. Here, we describe a case of PLH in a 70-year-old male with abdominal pain and a lesion, which was preoperatively diagnosed as a pancreatic no functional low-grade neuroendocrine tumor, and subsequent underwent a laparoscopic enucleation of the tumor. The postoperative pathology and immunohistochemical analyses confirmed the diagnosis of PLH.

The present work is focused on the development of an Ontological model to help the recognition of sulfuric minerals. This ontology will be implemented following the recommended construction methods. The diverse properties of the minerals to be stored in Ontologies can be extracted by means of the semantic query language. Finally, this ontological model can be used in the future for the implementation of a portal built with Semantic Web tools, so that mineral property searches are faster and more accurate.

El presente trabajo, está enfocado en el desarrollo de un modelo Ontológico para ayudar al reconocimiento de minerales sulfurados. Dicha Ontología se implementará siguiendo los métodos de construcción recomendados. Las diversas propiedades de los minerales al estar almacenada en Ontologías se pueden extraer mediante el uso del lenguaje de consultas semántico. Finalmente, dicho modelo Ontológico diseñado se puede usar en el futuro para la implementación de un portal construido con las herramientas de la Web Semántica, para que las búsquedas de propiedades de los minerales sean más rápidas y precisas.

Purpose: The role of tumor deposits (TDs) in the staging of gastric cancer is currently debatable. TDs are defined as tumoral nodules in perigastric adipose tissue with no evidence of lymphatic, vascular, or neural structures. Clinicopathological factors related to the presence of TDs are not well defined. This study aimed to identify the clinicopathological factors associated with the presence of TDs in resected gastric cancer patients. Materials and methods: This prospective study included patients diagnosed with gastric cancer and treated with D2 radical gastrectomy from January 2019 to January 2020. Univariate and multivariate analyses were performed to determine the factors related to the presence of TDs. Results: A total of 111 patients were eligible and TDs were present in 31 of them (28%). In the univariate analysis, male gender (p = 0.027), tumor size ≥ 5cm (p = ≤0.001), ser...

ST-segment elevation myocardial infarction (STEMI) is a clinical entity whose adequate treatment will depend on its prompt recognition, accurate diagnosis, and management in reperfusion networks. The first contact with these patients is generally done in centers without reperfusion capacity, attended by non-cardiologist doctors, and in centers far from hospitals with greater resolution capacity, something that is well known in our country. This manuscript proposes a strategy for the diagnosis and treatment of STEMI in centers without percutaneous coronary intervention capacity of the public health system in Peru, emphasizing not losing sight of electrocardiographic patterns compatible with coronary artery occlusion, adequate fibrinolysis and management of its complications, the treatment of infarction in special populations and highlighting the importance of the pharmacoinvasive strategy...

El infarto de miocardio con elevación del segmento ST (IMCEST) es una entidad clínica cuyo tratamiento adecuado dependerá de su pronto reconocimiento, diagnóstico certero y manejo en redes de reperfusión. El primer contacto con estos pacientes es generalmente en centros sin capacidad de reperfusión, atendidos por médicos no cardiólogos y en centros alejados de hospitales de mayor capacidad resolutiva, algo que es bien conocido en nuestro país. Este manuscrito propone la estrategia de diagnóstico y tratamiento del IMCEST para centros sin capacidad de intervención coronaria percutánea del sistema público de salud en el Perú, haciendo hincapié en no perder de vista patrones electrocardiográficos compatibles con oclusión de la arteria coronaria, fibrinolisis adecuada y manejo de sus complicaciones, el tratamiento del infarto en poblaciones especiales y resaltando la importan...

Background: Thymomas are a group of rare neoplasms of the anterior mediastinum. The objective of this study was to describe the demographics, clinical characteristics and treatment approaches in Latin America.Methods: This was a retrospective multicenter cohort study including patients with histologically proven thymomas diagnosed between 1997 and 2018. Demographics, clinicopathological characteristics and therapeutic outcomes were collected locally and analyzed in a centralized manner. Results: A total of 135 patients were included. Median age at diagnosis was 53 years old (19-84), 53.3% (n = 72) of patients were female and 87.4% had an ECOG performance score ranging from 0-1. A total of 47 patients (34.8%) had metastatic disease at diagnosis. Concurrent myasthenia gravis occurred in 21.5% of patients. Surgery was performed in 74 patients (54.8%), comprising 27 (20%) tumorectomies and 4...
