Loayza-Alarico Jhony A. De La Cruz -Vargas Willy Ramos <p>On January 30, 2020, with more than 9,700 confirmed cases in China, the World Health Organization declared the coronavirus outbreak to be a public health emergency of international concern. At the end of January, the National Center for Epidemiology, Prevention and Control of Diseases (CDC-Peru) of the Ministry of Health prepared the “National Plan of Preparation and Response to the Introduction of the coronavirus 2019-nCoV”, where one of the strategic components was strengthen the epidemiological response through mitigation actions that allow early identification of cases, diagnosis, follow-up of contacts and identification of people with risk conditions.</p> 2020-06-10T08:29:35+00:00 ##submission.copyrightStatement## COVID-19: The world on pause. How we face this new pandemic? 2020-09-23T06:13:30+00:00 Gabriel Lapman <p>The Covid-19 pandemic, popularly known as coronavirus, was announced in an article by the American Society of Microbiology that already in 2007 warned about the dangers of the consumption of exotic animals in different Chinese communities. The background of SARS and MERS helps us understand that humanity is not prepared for such severe contingencies. Economies are sold out and there is no leadership; health systems are deficient: the result of years of underinvestment, low salaries and lack of qualified personnel to attend, follow, control and direct infectious diseases.</p> 2020-06-10T08:10:23+00:00 ##submission.copyrightStatement## COVID-19: Socio-cultural influences and adherence to governmental strategies for social isolation in Peru 2020-09-23T06:14:25+00:00 R Dammert-Elejalde <p>On March 15, Peruvian President Martín Vizcarra, in a message to the nation, announced that, with 71 positive cases, he was declaring a state of emergency, just 9 days after announcing on national television the presence of the first positive case, a worker of a well-known airline. In hindsight, we all forget that it was considered at the time a very drastic decision, even a hasty one; but the Head of the Nation was definitely already completely soaked in the world's reality, just four days away from the late declaration by the WHO, on March 11, 2020, of COVID-19, as a Pandemic.</p> 2020-06-10T08:23:49+00:00 ##submission.copyrightStatement## Fever, Cough and Cold What else do you have? Impact of the Sars-Cov-2 Pandemic in the consultation for respiratory diseases in the pediatric emergency 2020-10-09T22:50:17+00:00 Viviana Pavlicich <p>When fall arrives, pediatric emergency services (SEP) professionals know before the trees decide to change their leaves. The increase in the number of patients is as important as the repetition of the reasons for consultation and the explanations about the futility of ¨treatments for viruses¨. In addition to colds with and without fever that lead EPS to collapse, there are severe symptoms of bronchiolitis, laryngitis, asthma attacks and pneumonia that demand specialized care.</p> 2020-08-09T04:00:12+00:00 ##submission.copyrightStatement## Kidney biopsy.

De La Cruz-Vargas <p><strong>Introduction:</strong> Due to the presence of Covid-19 in the world, several countries, including Peru, have taken measures, including compulsory social isolation (quarantine). The inability of people to carry out their daily activities has directly affected their lifestyles. A population quite susceptible to these changes are university students. <strong>Objectives:</strong> To develop a validation scale to know what are the changes in lifestyles during the quarantine period in a population of university students from Lima, Peru. <strong>Results:</strong> The final scale was made up of 25 items. Bartlett's sphericity test was significant (3514.19, gl = 300, p &lt;0.001) and the Kaiser-Meyer-Olkin sample size adequacy indicator was adequate (0.845). The four thematic areas were changes with respect to 1) Eating habits; 2) Harmful habits; 3) Physical activity; and 4) Use of communication media. As it was a Likert-type ordinal measurement scale, the results were confirmed through the Factor Analysys program, obtaining a KMO of 0.80 (reliable) and the significant Bartlett sphericity test (5528.8; p &lt;0.001; gl = 300). confirming the existence of 7 components that explain 63% of the variance. <strong>Conclusions:</strong> This scale gathers the psychometric properties to be considered a useful, valid and reliable instrument to measure these changes in students of health science careers, being necessary to validate it prospectively in other careers and countries.</p> 2020-08-09T04:23:27+00:00 ##submission.copyrightStatement## Surgical complications in pediatric patients with complicated acute appendicitis in open and laparoscopic surgeries in a national referral center 2020-10-23T06:53:30+00:00 Carolina Fabiola Paz Soldán Mesta Hilda Liliana Gonzales Carlos Enrique Paz Soldán Oblitas <p><strong>Objective:&nbsp;</strong>To determine the incidence and type of complications after an appendectomy in patients with appendicitis complicated by peritonitis in relation to the type of surgical intervention and the time elapsed from the onset of the symptoms to surgery.&nbsp;<strong>Methods:&nbsp;</strong>157 medical records of patients from the Pediatric Surgery Service of HNGAI and diagnosed with acute appendicitis complicated with peritonitis were evaluated.

Preclinical test 2020-10-09T22:58:47+00:00 José Gonzales-Daga Rafael Alvis-Dávila José Luís Rafael Pino-Gaviño Roger Iziga-Goicochea <p>The "mashua", Tropaeolum tuberosum Ruiz &amp; Pavón, 1802 is a plant species native from Peru and a resource of great nutritional value. In addition, there are several investigations carried out in the last decade in which its effects on mammal fertility have been verified. In this work, we evaluate the effect of the aqueous extract of <em>T. tuberosum</em> on the development of the preimplantation embryos of <em>Mus musculus</em>. The aqueous extract was administered <em>ad libitum</em>, in a concentration of 50 g / Kg of body weight, to three groups of mice (n = 24) during 8, 16 and 35 days; the control group drank only tap water. Each group of males were crossed with females of fertile age, the presence of a vaginal plug indicated the 0th day of embryonic development. At 72 h the uterine horns were perfused and the stage of development, condition and embryonic morphology were evaluated. Differences were found between the control and treatment groups. Our results demonstrate that the aqueous extract of <em>T. tuberosum</em> alters the quality of the mouse sperm, affecting the ability of the embryo to develop normally to the blastocyst stage.</p> 2020-08-09T04:16:20+00:00 ##submission.copyrightStatement## Genetic basis of pulmonary arterial hypertension 2020-09-12T02:47:37+00:00 Maria del Carmen Castro-Mujica Hugo Abarca Barriga <p>Pulmonary arterial hypertension (PAH) is a heterogeneous disease where genes play an important role.

To date, there is no specific antivirus treatment for COVID-19. The use of convalescent plasma transfusions could be of great value in the current pandemic. Recently recovered SARS-CoV-2 patients who may be suitable donors undergo apheresis in order to obtain convalescent plasma containing high-titer antibodies, granted they meet blood donation criteria. In this review, we summarize existing literature around convalescent plasma as a therapeutic option for COVID-19. It is important to note that the appropriate timing on convalescent plasma administration and the severity of its adverse effects needs to be further studied. Convalescent plasma provides the potential to render an immediate promising treatment option while evaluating existing drugs and developing new specific vaccines and therapies.</p> 2020-09-06T02:09:06+00:00 ##submission.copyrightStatement## Electrospinning: Advances and applications in the field of biomedicine 2020-09-12T02:47:37+00:00 Hugo Mauricio Gonzales Molfino Alexander Alcalde Yañez Valery Veronica Valverde Morón Dulce Virghynia Villanueva Salvatierra <p>Nanofiber production in scaffolds using electrospinning technology encompasses many physical and chemical parameters that have been studied and have not yet been fully elucidated.
