Obstetric hemorrhage is the most common cause of maternal mortality in the world. Our knowledge of hemorrhagic shock pathophysiology and management has significantly improved during the last decades. Blood transfusion has emerged as a strategy with great impact on patients’ survival. Consequently, it is crucial to have a protocol of massive blood transfusion available for cases of massive obstetric hemorrhage.

El objetivo de este trabajo de Tesis es realizar un estudio de las características y del desempeño del protocolo SCTP (Stream Control Transmission Protocol) y contrastarlo con los protocolos clásicos de la capa de transporte. SCTP es un protocolo que trabaja en la capa de transporte, el cual diferencia de TCP que permite crear un solo canal de transmisión, con SCTP se puede crear diversos canales de conexión que trabajan en paralelo, de esta manera la transmisión es más rápida entre cliente y servidor. Todo el trabajo se realiza con aplicaciones existentes que funcionan bajo el entorno de Linux con el objetivo de mostrar los beneficios al usar SCTP en lugar de TCP, además se muestran herramientas útiles para crear aplicaciones que trabajen sobre SCTP ya que este trabajo de Tesis de Pregrado es el trabajo previo para una posterior Tesis de Maestría o de Doctorado.

The main objective on this research is the development of finding the optimal parameters for a routing algorithm for network routers based on the ant algorithm described as AntNet. The optimum parameters for this type of algorithm improve a more efficient alternative to those given by the RIP, EIGRP and OSPF routing protocols, to be applied in a data network. This shall be tested in two networks and routers defined, taking the same characteristics for the three groups: RIP, OSPF and by the result provided by the genetic algorithm implemented using a static network. The system recognizes the best path between networks of routers, based on the principle of AntNet networks or networks of ants, which are the best way from exploring almost all roads, using estimergia to go there and make optimal. MatLab was used to detect the best way. Later this road was implemented in a real network data, s...

Introduction: Autologous blood transfusion, also known as autotransfusion, allows a patient to receive their own previously collected and stored blood, reducing the risks associated with homologous transfusion. Objective: To analyze and describe the modalities of autologous transfusion, its benefits, indications, limitations, and risks in different clinical scenarios. Methods: A narrative review of studies published between 2015 and 2025 was conducted using biomedical databases such as PubMed, Cochrane, and the Pan American Health Organization (PAHO). A total of 43 references were included, encompassing systematic reviews, clinical trials, and observational studies. The methodological quality of the studies was assessed, and information was synthesized according to each autologous transfusion modality: preoperative blood deposit, acute normovolemic hemodilution, and intraoperative bloo...

Introduction: Cough is a key symptom of tuberculosis (TB) as well as the main cause of transmission. However, a recent literature review found that cough frequency (number of coughs per hour) in patients with TB has only been studied once, in 1969. The main aim of this study is to describe cough frequency patterns before and after the start of TB treatment and to determine baseline factors that affect cough frequency in these patients. Secondarily, we will evaluate the correlation between cough frequency and TB microbiological resolution. Methods: This study will select participants with culture confirmed TB from 2 tertiary hospitals in Lima, Peru. We estimated that a sample size of 107 patients was sufficient to detect clinically significant changes in cough frequency. Participants will initially be evaluated through questionnaires, radiology, microscopic observation drug susceptibility...

Controlling norovirus transmission in units with immunocompromised patients is challenging. We present a cluster of norovirus cases that occurred on a stem-cell transplant unit and the prevention efforts that were implemented to limit the outbreak. Protocols developed to control this cluster may provide a model for other facilities.

Viruses have been present throughout human history, causing diseases due to infections and food poisoning; they have caused frequent public health problems worldwide. These illnesses are usually mild, moderate, or severe in nature. The personal hygiene of food handlers and processing processes should be checked periodically. Virus detection protocols and safety measures should be continually reviewed as viruses change their mode of infection. The objective of this review was to discuss the possible routes of virus transmission to humans through food. Important topics have been reviewed such as: definition of food viruses, presence, and types of viruses in food, enteric viruses, zoonotic viruses, water as a means of transmission, risks of infection, other non-conventional foods as potential transmitters of viruses and food safety, in addition to current and future challenges, research wor...

We present the first hardware implementation for a FPGA-based universal link for the transmission of different low-voltage differential signaling (LVDS) connections through a single LVDS connection between different devices. The main objective of this work is to reduce the number of wires in a network, for example in some satellites, with several groups of devices, to a single LVDS connection. This paper proposes a new communication protocol for successfully coding and decoding the data sent through the single connection. We propose a solution for one of the difficulties of LVDS standard due to the amount of wires needed for a duplex connection, significantly reducing the amount of wires required for a large network. The proposed solution has been implemented in an Atlys board with a Spartan 6 FPGA showing promising results.

La crianza de camarones (Macrobrachium rosenbergii) en piscinas con comederos automáticos ha crecido en el Perú debido a la alta demanda de exportación [1]. Esta compleja actividad requiere el monitoreo constante de las condiciones del agua, distribución de los animales y la alimentación. El Internet de las cosas (IoT) es una red de dispositivos conectados a Internet capaces de comunicarse entre sí. Estos sistemas suelen sensar parámetros de interés mediante nodos de bajo consumo energético [2]. La tecnología LoRa (Long Range) permite una comunicación eficiente y de bajo costo para aplicaciones IoT en ciudades inteligentes, agricultura y automatización industrial [3]. La tecnología ha demostrado ser exitosa en contextos agrícolas por su flexibilidad y escalabilidad [4]. Este trabajo propone desarrollar una red LoRa con salida a Internet para conectar comederos automáticos ...

This research aims to make the network segmentation and prioritization of bandwidth use, because the current design of the network of the University City of the National University of San Martin - Tarapoto is a flat network with VLAN default, therefore there is no adequate segmentation collision domain and broadcast domain, which drastically affects the performance of the same level of packet transmission between buildings that are ends of the star and the hub node. This causes network latency on dates and times peak transfer rate degraded by excessive traffic and not segmented data and damaging or retarding the academic and administrative processes. Therefore, as part of the solution to the needs identified in this research, redesigning the network to support Virtual LAN networks arises, and thus target areas subnets for a higher level of protection; provide security Control Lists (ACL'...

ABSTRACT Information and communication technologies are revolutionizing the different areas of knowledge, and medicine is an area where the uses of new technologies are put into practice for the well-being of people. But these new ways of using technology produce a high risk when information is required to be transmitted, either due to the loss of information also due to the risk that the information may be altered for different reasons and due to the theft of information. It is for these reasons that it is necessary to have certain mechanisms to be able to achieve the maximum integrity of the information, in this work a methodology is presented to be able to safely transmit information from the different medical teams to medical information based on an organization of the information, in order to present in a practical way its possible implementation in the development of systems to dev...
