Introducción. La pandemia por coronavirus 2019 (COVID-19) se ha extendido en más de 100 países. La información específica sobre su comportamiento en el embarazo y parto sigue siendo limitada. Objetivo. Describir las características materno perinatales de pacientes gestantes con COVID-19 en un hospital terciario. Métodos. Estudio descriptivo. Se seleccionó todas las gestantes hospitalizadas por el servicio de emergencia de gineco-obstetricia entre el 24 de marzo y el 07 de mayo del 2020 y que tuvieron diagnóstico de infección por SARS-CoV-2, mediante la prueba rápida o la prueba RT-PCR. Se revisó la historia clínica y registros hospitalarios buscando variables sociodemográficas, antecedentes, manifestaciones clínicas, serología materna, complicaciones obstétricas, vía de parto y aspectos perinatales. Resultados. Se encontró 41 casos de pacientes con diagnóstico de SARS-CoV-2. Un 9,2% tuvo resultado de prueba rápida positiva, Los síntomas más comunes fueron tos en 84,6%, fiebre en 76,9% y dolor de garganta en 61,5%. Un 68.2% estuvo asintomática, 19,5% tuvo enfermedad leve y 7,3% moderada. Dos casos de neumonía severa requirieron ventilación no invasiva. No se registró muerte materna. 21,7% de los partos fue vía vaginal y 78,3% por cesárea. Hubo un caso de neonato por parto vaginal con PCR positivo al octavo día de vida. Conclusiones. Hubo un alto porcentaje de pacientes gestantes PCR positivas asintomáticas. Es necesario implementar el tamizaje universal en parturientas en el protocolo de flujo de gestantes en cada institución. / Introduction: The pandemic of coronavirus disease 2019 (COVID-19) has spread to more than 100 countries. Specific information about its behavior in pregnancy is still limited. Objective: To describe the maternal and perinatal characteristics of pregnant patients infected with COVID-19 and their newborns in a tertiary referral hospital. Methods: Descriptive study. Subjects were all pregnant patients admitted to the OB/ GYN Emergency Department of the Edgardo Rebagliati Martins National Hospital from March 24 to May 7, 2020, who were diagnosed with SARS-CoV-2 infection by rapid test or by RT-PCR test. Medical and hospital records were reviewed to retrieve sociodemographic data, patient’s history, clinical manifestations, maternal serology, obstetric complications, delivery mode and perinatal aspects. Results: 41 patients diagnosed with SARS-CoV-2 were identified. 9.2% of all admissions had a positive rapid test. The most common symptoms were cough in 84.6%, fever in 76.9% and sore throat in 61.5%. 68.2% of the patients were asymptomatic, 19.5% had mild illness and 7.3 %, moderate. 2 cases progressed to severe pneumonia requiring non-invasive ventilation. No maternal deaths were recorded. 21.7% were vaginal deliveries, while 78.3% were C-sections. One baby born in a vaginal delivery had a positive PCR result on day 8. Conclusions: A large percentage of asymptomatic pregnant patients had a positive PCR test. Implementing universal screening among patients in l flow protocol is necessary for all institutions.

Objetivos: Estimar la prevalencia y los factores asociados a la intención de vacunación (IDV) contra la COVID-19 en el Perú. Materiales y métodos: Estudio transversal analítico utilizando una encuesta realizada por la Universidad de Maryland, EUA, en Facebook. La variable dependiente fue la IDV. Se calcularon razones de prevalencia (RP) crudas y ajustadas, con sus intervalos de confianza al 95% (IC95%), mediante modelos lineales generalizados de la familia Poisson para evaluar la asociación de variables sociodemográficas, el cumplimiento de estrategias comunitarias de mitigación, los síntomas de la COVID-19, la salud mental y la aceptación de la vacunación ante la recomendación (AVR) por diversos actores y autoridades sanitarias. Resultados: Se analizaron los datos de 17 162 adultos. La prevalencia general de la IDV fue del 74,9%. Se asociaron a una menor prevalencia de la IDV ser de sexo femenino (RP = 0,95; IC95%: 0,94-0,97), vivir en un pueblo (RP = 0,95; IC95%: 0,91-0,99) o en una aldea u otra área rural (RP = 0,90; IC95%: 0,86-0,93) y la AVR de políticos (RP = 0,89; IC95%: 0,87-0,92). Contrariamente, tener síntomas de COVID-19 (RP = 1,06; IC95%: 1,03-1,09), inseguridad económica (RP = 1,04; IC95%: 1,01-1,06), miedo a enfermar o que un familiar enferme de COVID-19 (RP = 1,49; IC95%: 1,36-1,64) y la AVR de familiares y amigos (RP = 1,10; IC95%: 1,08-1,12), trabajadores de la salud (RP = 1,29; IC95%: 1,26- 1,32), la Organización Mundial de la Salud (RP = 1,34; IC95%: 1,29-1,40) y funcionarios del gobierno (RP = 1,18; IC95%: 1,15-1,22) se asociaron con mayor prevalencia de IDV. Conclusiones: Tres cuartas partes de los encuestados manifiestan IDV. Existen factores potencialmente modificables que podrían mejorar la aceptación de la vacuna. / Objectives: To estimate the prevalence and factors associated with COVID-19 vaccination intention (VI) in Peru. Materials and methods: Analytical cross-sectional study using the survey conducted by the University of Maryland, USA, on Facebook. The dependent variable is VI. Crude and adjusted prevalence ratios (PR) were calculated, with their 95% confidence intervals (95%CI) using generalized linear models of the Poisson family, to evaluate the association of sociodemographic variables, com- pliance with community mitigation strategies, symptoms of COVID-19, mental health and acceptance of vaccination before the recommendation (AVR) by various actors and health authorities, with the ITV. Results: Data from 17,162 adults were analyzed. The overall prevalence of VI was 74.9%. A lower prevalence of VI was associated with the female sex (PR=0.95; 95%CI:0.94-0.97), living in a town (PR=0.95; 95%CI:0.91-0.99) or village or other rural area (PR=0.90; 95%CI:0.86-0.93) and the AVR of politicians (PR=0.89; 95%CI:0.87-0.92). Conversely, having COVID-19 symptoms (PR=1.06; 95%CI:1.03-1.09), economic insecurity (PR=1.04; 95%CI:1.01-1.06), fears of becoming seriously ill or that a family member becomes seriously ill from COVID-19 (PR=1.49; 95%CI:1.36-1.64) and the AVR of family and friends (PR=1.10; 95%CI: 1.08-1.12), healthca- re workers (PR=1.29; 95%CI: 1.26-1.32), World Health Organization (PR=1.34; 95%CI: 1.29-1.40) and government officials (PR=1.18; 95%CI: 1.15-1.22) was associated with a higher prevalence of VI. Conclusio of the respondents had VI. There are potentially modifiable factors that could improve vaccine acceptance.

Se reporta el caso de un varón de 62 años quien presentó tos y dolor abdominal por dos semanas, con hallazgos tomográficos pulmonares compatibles con probable infección por SARS-CoV-2, que recibió tempranamente corticoterapia a dosis altas y de manera ambulatoria. El paciente presentó evolución tórpida, fue hospitalizado y falleció en el posoperatorio inmediato por un cuadro de abdomen agudo quirúrgico. El estudio anatomopatológico mostró estructuras parasitarias con características compatibles con amebas, como causa de una colitis aguda fulminante complicada, con perforación múltiple y peritonitis aguda. La colitis aguda fulminante por amebiasis intestinal en el contexto de un paciente con probable COVID-19 no había sido reportada en el Perú. Resulta importante resaltar la presentación fulminante con desenlace fatal de esta infección parasitaria prevalente en nuestro medio, en el contexto del uso de corticoides ante una probable infección pulmonar por COVID-19. / We report the case of a 62-year-old male with cough and abdominal pain for two weeks, associated with pulmonary tomographic findings compatible with probable infection by SARS-CoV-2, and who received high doses of early corticotherapy as an outpatient. The patient showed clinical deterioration, was hospitalized and died in the immediate postoperative period due to acute surgical abdomen. The anatomopathological study showed parasitic structures with characteristics compatible with amebae, which was pointed to as the cause of a complicated acute fulminant colitis, with multiple perforations and acute peritonitis. Acute fulminant colitis due to intestinal amebiasis in the context of a patient with probable COVID-19 had not been previously reported in Peru. It is important to highlight the fulminant presentation with fatal outcome of this prevalent parasitic infection, in the context of corticosteroids use in a probable SARS-CoV-2 pulmonary infection.

SARS-CoV-2 började cirkulera i slutet av 2019 och ungefär tre månader senare klassades utbrottet som en pandemi. Idag, ungefär ett och ett halvt år efter virusutbrottet kämpar människor i hela världen fortfarande för att ta sig ur kriserna som pandemin orsakar. Trots stora forskningsinsatser är det ännu mycket som är ovisst kring virusets uppkomst. Olika teorier försöker bevisas men till dagens datum är det inte bekräftat var SARS-CoV-2 har sitt ursprung. Det verkar troligt att SARS-CoV-2 har en gemensam förfader med β-coronaviruset RaTG13. Det är sannolikt att fladdermus tillsammans med minst en mellanvärd har varit inblandad i uppkomsten av viruset. Viruset har gett upphov till flera varianter som spridit ut sig i världen. Globalt samarbete med övervakning av mutationer och varianter är viktigt för hur utvecklingen av pandemin ska fortgå. Med SARS-CoV-2 och Covid-19-pandemin som utgångspunkt analyseras möjligheter och utmaningar med undervisning i gymnasieskolan om aktuella stora händelser. / The outbreak of SARS-CoV-2 occurred at the end of 2019 and three months later, it was declared as a pandemic. Today, roughly one and a half years later, people across the world are still struggling to get out of the crises caused by the pandemic. Despite the huge efforts within science, much is still uncertain about the virus’ origin. Different theories are trying to be proven by scientists but to date, there is no confirmation from where the virus has its origin, nor whether one or several intermediate hosts have been involved. It seems likely that SARS- CoV-2 has a common ancestor with the bat β-coronavirus RaTG13. Therefore, it is probable that bats with at least one other intermediate host have been involved in the origin of the virus. Several variants have emerged and spread throughout the world. Global cooperation in regards of surveilling mutations and variants is of great importance regarding the development of the pandemic. Using SARS-CoV-2 and the Covid-19 pandemic as a focal point, there is an analysis showing opportunities and challenges when teaching big contemporary events.

Self-medication impacts both negatively and positively the health of people, which has become evident during the COVID-19 pandemic. The study aimed to assess the prevalence of self-medicated drugs used for respiratory symptoms, as COVID-19 preventive, for its symptoms or once tested positive. To determine the perception of symptom relief and demographic variables that promote self-medication in Peru. We performed a cross-sectional, analytical, multicenter study in 3792 study respondents on the use, the reason for use, and perception of relief after the use of six drugs during the quarantine period. An online questionnaire was developed, pretested and submitted to the general public. Multivariable logistic regression was used to ascertain factors that influence an individual's desire to self-medicate, associations were considered significant at p < 0.05 and using region (coast, mountain and jungle) as cluster group. The majority of respondents self-medicated with acetaminophen for respiratory symptoms and mainly because they had a cold or flu. It was observed that all the surveyed drugs (acetaminophen, ibuprofen, azithromycin, penicillin, antiretrovirals and hydroxychloroquine) were consumed for various symptoms including: fever, fatigue, cough, sneezing, muscle pain, nasal congestion, sore throat, headache and breathing difficulty. Over 90% of respondents perceived relief of at least one symptom. Multivariable logistic regression showed that older people have a higher frequency of antiretroviral self-medication, respondents who currently have a job had a higher frequency of penicillin self-medication, and that respondents from the Andes consumed less acetaminophen, while the ones from the rainforest consumed it more. There were significant percentages of self-medication, including drugs without sufficient scientific evidence. Age, region where one lived and job status were variables associated with self-medication frequency. Continuous awareness and sensitization about the risks of self-medication are warranted. / Revisión por pares
