The National Health System of Ecuador (SNS) is characterized by its segmentation and fragmentation, which limits the implementation of public policies in the sector and provisional services. This study was conducted using an analytical framework of governance in health and observations of the type of principal-agent relations in the provision of public services. It is based on a case study that shows how the institutional configuration of SNS in Ecuador unfolds and how this affects the implementation of public policies. The results show that despite the designed mechanisms in place to improve the coordination of the health system, the institutional structure hinders the implementation of integrated networks of provision services.

Transfusion therapy is an important therapeutic alternative, but the risk of transmitting infections through this route constitutes a clinical and public health problem, with magnitude and heterogeneous associated factors, depending on the reference population of each blood bank. In this way, the objective of this work is to describe the epidemiology of infectious diseases in blood donors: types of donors, availability and safety of blood, for which a descriptive narrative documentary research was used, which allowed selecting articles related to the subject, and in turn gain knowledge with the literature search. The results of the study indicate the prevalence of infectious diseases at a global level, presenting a great increase in HIV, VBH, HTLV-1 and Syphilis, the high frequency among infectious diseases has even reached 75% of the population under study with the virus of human immunodeficiency HIV, taking into account that the availability of blood donation units is established by a large number, the average availability evidencing the types of donors who attend different blood banks that determine different laboratory tests, the following stand out: Anti-HIV tests, VDRL, AgsHB and AntiVHC for the detection of infectious diseases. The prevalence of infection in the blood donor community is found with hepatitis B, C, HIV, malaria, syphilis, parvovirus B-19, as well as infections of bacterial origin that currently generate greater concern in the Health.

The basis of this project is the design and development of an augmented reality mobile application. The application has been developed in the free software UniteAR and aims to reduce downtime focused on the area of preventive maintenance of the electrohydraulic press for manufacturing processes in domestic kitchens; the purpose of the application is to reduce downtime due to corrective and/or preventive maintenance of the electrohydraulic press, in addition, the technician will find information of the instrument to be replaced and the guide of the tasks to be performed. The implementation of the application is focused on the equipment identified as critical, since the downtime of such equipment generates downtime, stoppages in the processes, which generate a low efficiency of the machinery.

Hyperprolactinemia is a hormonal disorder related to the hypothalamus-pituitary axis, it is diagnosed by a high serum level of prolactin, in women from 20 to 25 ng/ml and in men, 17 ng/ml, this disorder can have various causes. The objective of this research work is to analyze the prevalence, diagnosis, causes and consequences of hyperprolactinemia. For this, a documentary-type descriptive methodology was designed, where a bibliographic review was carried out, the results showed that the prevalence is established at less than 1% worldwide, although in certain specific populations a prevalence of 50% more or less is reached, the diagnosis was made by measuring prolactin levels, in addition to other resources such as liquid chromatography or magnetic resonance imaging, this disorder can be caused by various factors, such as the use of antipsychotics, motherhood and lactation, or the presence of other diseases such as kidney failure. As for the consequences, there may be hormonal alterations such as delayed puberty, amenorrhea, galactorrhea, and in men sexual dysfunction and various other consequences that compromise the health status of the person suffering from this disorder can manifest, so the measurement of levels Thyrotropin and prolactin levels are excellent biomarkers for the diagnosis of hyperprolactinemia except in clinical conditions such as antipsychotic induction or chronic renal failure, and analysis by liquid chromatography or magnetic resonance imaging can improve this process.

In this article, an analysis of the operation and characterization of sensors for the measurement of the level of oxygen in the blood of users is carried out, as well as the characteristics of software and hardware that they may present are considered. The way in which the SpO2 sensors work, and the variables involved in the measurement of the oxygen levels presented are described. A visual and mathematical comparison of the measurements made by these devices and the margin of error that may occur between the measurements made by an embedded device for measuring SpO2 levels, a commercial watch with said integrated function and an Arduino sensor that It requires the development of programming and hardware to put it into operation.

Dengue is one of the neglected tropical diseases, it is the most common mosquito-borne viral disease, with a large burden of disease worldwide, it is transmitted by a human-mosquito-human cycle with the Aedes aegypti mosquito as the primary vector and Aedes albopictus as a secondary vector. Aedes was originally found in tropical and subtropical areas, but now it has spread to almost all continents based on the present problem, the following objective is to analyze the prevalence and risk factors in the global transmission of dengue. This documentary-type systematic bibliographic review study aims to determine the prevalence of dengue transmission and global risk factors. It was concluded that dengue is a neglected disease and one of the public health problems that manifests itself in winter times, therefore its prevalence according to 2020 studies is very high in underdeveloped countries in the Caribbean and Latin American region, the main risk factor. Is the environmental situation. Dengue disease can be controlled with the contribution of the population, with the help of the different government institutions that make up the health sector. Through this work, the scientific community continues to provide the needs to strengthen prevention against dengue infection.

This work was carried out through a systematic review in order to analyze the association between hyperlipidemia and infection by the human immunodeficiency virus. A retrospective descriptive investigation was carried out, with a documentary design through a systematic review. Information sources were selected from web databases, such as Pubmed, BMC, Google Scholar, Redalyc, Scielo, Dialnet, Science Direct, web pages and Theses, 42 scientific articles were selected for the 2013 to 2022 bibliographic review, in Spanish, English and Portuguese. It was evidenced that the appearance of hyperlipidemia is associated with people taking antiretroviral therapy treatment, and the complications that arise throughout their lives as a patient receiving treatment, causing abnormal levels of triglycerides and cholesterol with versatile changes in low-density lipoproteins and high-density lipoproteins. In conclusion, the theoretical context indicates that, in patients infected with the human immunodeficiency virus, they are linked to metabolic alterations and it was shown that the increase in blood lipids is only an alteration of the health complications that cause risks. vascular, coronary and physical.

In this research article, the training of an algorithm for user recognition and identification is developed, using an unmanned aerial vehicle with a video camera for face focusing, specifically with the Tello EDU Drone. Within the training of the algorithm in the Python software with the developer Pycharm, three instruction models FISHER, EIGEN and LBPH were used, which presented efficient results in the detection of identification patterns. The EIGEn and FISHER model have a minimum margin of error on the other hand, the LBPH model has a lower detection error, as well as a better response time of result, in the tests carried out to users, depending on the number of samples.

The present investigation had as the analysis of hyperuricemia as an indicator of cardiovascular risk in older adults, since it is a problem that is increasing objectively decreasing the health of this group in particular. The methodology used is documentary design, descriptive and bibliographic review, with emphasis on articles published within the last 8 years in different databases such as Scielo, Pubmet, Elsevier, Redalyc, Google Scholar and Dialnet. In the results it was evidenced that many investigations support that hyperuricemia is an indicator to develop cardiovascular diseases, and the people who are most exposed are the elderly; presenting a higher incidence of mortality in patients from 70 to 79 years of age, so its study is useful in primary care, carrying out preventive actions on possible complications in the health of patients. According to what has been studied, it is important to analyze the mentioned topic since it is a reference to know the reality of this health problem and the actions to prevent it.
