Item Uso da terapia por fotobiomodulação a laser no tratamento do paciente com covid-19 em unidade de terapia intensiva(Universidade Brasil, 2022) Neves Neto, Messias Augusto das; Tim, Carla Roberta; Garcia, Lívia AssisThe pandemic context ended up causing the exploration of new treatment methods in the face of the conditions presented by patients in this period. In this bias, photobiomodulation therapy has been characterized as a viable therapeutic aspect for the treatment of patients with COVID-19 in the Intensive Care Unit, since it has great potential for biological alteration. To demonstrate the feasibility of the treatment, a case report was carried out that aimed to evaluate the effects of photobiomodulation as an adjuvant treatment in a patient with COVID-19 admitted to an intensive care unit (ICU). A 68-year-old man with severe COVID-19 received 5 sessions of PBMT by laser, once daily. The treatment protocol consisted of the association of the application of local PBMT with 808 nm laser and the application of a transdermal laser in the radial artery with a 660 nm laser. The patient was evaluated before and after treatment through radiological evaluation, blood tests and oxygen requirement. Oxygen saturation (SpO2) increased from 92% in the support of oxygen with a mask without rebreathing 13 L/min to 95% in the delivery of O2 2 L/min in a nasal catheter, tolerating the withdrawal of oxygen therapy for 20 minutes. This case report showed that the use of photobiomodulation therapy in the adjuvant treatment of a patient with COVID-19 decreases oxygen needs over several days and without the need for a ventilator. Future controlled clinical trials are needed to assess the effects of PBMT on clinical outcomes in patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS).Item Análises epidemiológica e espacial da Covid-19 no Estado do Piauí(Universidade Brasil, 2021) Macedo, Glauber Bezerra; Tim, Carla Roberta; Garcia, Lívia AssisThe emergence of a new coronavirus in humans, first diagnosed in 2019, has many deaths and serious survival and psychosocial consequences. Through statistical tools and techniques associated with geographic technologies, this ecological, analytical and exploratory study is being developed, whose general objective is to carry out epidemiological and spatial analyzes of the distribution of confirmed cases and deaths from Coronavirus 2019 disease (Coronavirus Disease 2019 - COVID-19), in the year 2020, in the state of Piauí, Brazil. The variables listed are being assigned via the IBGE and SESAPI database. All confirmed cases and deaths with COVID-19 infection that were reported in 2020 in that state were included in the study. In the epidemiological analyzes descriptive statistics were carried out and in the spatial analyses, maps are being constructed using geoprocessing techniques, through the statistical analysis of Moran Global and Local. Preliminary results showed that, in 2020, 143,179 confirmed cases and 2,840 deaths caused by COVID-19 were reported in Piauí. A higher percentage of cases was observed in relation to females, young adults, and deaths in elderly, males, with chronic diseases. The capital Piauiense led the number of cases and deaths from the disease, probably due to the high population density. However, when considering the incidence and mortality coefficients of COVID-19, the highest rates in the state were considered in the municipalities of União and Água Branca, respectively. The spatial analysis of the cases showed clusters of high-high pattern of cases of the disease in the metropolitan region of Teresina, the region between Rios and the region of Tabuleiros do Alto do Parnaíba. A high-high cluster for mortality was verified in fillings in the region of Entre Rios and Vale do Sambito. The analyzes performed provided the visualization of spatial clusters and an identification of vulnerable areas, resulting in information that was not visualized working only with tabular data.Item COVID-19 e os mecanismos de infecção relacionados aos hábitos e estilo de vida(Universidade Brasil, 2022) Carvalho, Jucilene Santos de; Santos, Laurita dosThe COVID-19 pandemic presented itself as a major public health problem for Brazil and the world. It had an impact on health indicators such as morbidity, mortality and health expenditures, and important economic impacts related to the closure of establishments and social isolation. Given this scenario, this research was proposed for the municipality of São Caetano de Sul with the objective of analyzing the relationship between behaviors and life habits of people with coronavirus infection, and comparing the data between two specific moments of circulation of different variants. – Delta and Omicrôn. The data presented in this research are the result of 496 valid interviews. In all, there were 218 positive tests for COVID-19 and 278 negative ones. Among the positives, 44 during the circulation of the Delta variant and 176 during the circulation of the Omicrôn variant. The data analyzed and presented demonstrate how the universe of coronavirus infection is multifactorial and dependent on many conditions. This characteristic is even accentuated when the scenarios of two circulations of different variants are compared, as presented in the study. Some data are similar to what the pandemic presented at a global level (such as data related to gender), but others are well circumscribed to the Brazilian reality, or even regional, considering the region of residence where the participants lived (such as data related to race/color). Some behaviors associated with coronavirus control in national and international literature did not have similar results in this research, such as the number of vaccine doses, social isolation and working conditions. There was no significant variation between respondents who tested positive or negative. This situation can be explained by the profile of the respondents of this survey: they were symptomatic people who sought a diagnostic support service to find out whether or not they were contaminated by the coronavirus.Item O uso de relógios inteligentes na aferição de frequência cardíaca de pacientes internados com diagnóstico de hipertensão arterial sistêmica com COVID-19(Universidade Brasil, 2021) Vieira, Leonardo Matos; Marciano, Fernanda Roberta; Carvalho, Jancineide de Oliveira deWearable technologies become an important topic in the field of health technology for the monitoring and storage of health-related data. Pulse oximetry is the most used wearable in the continuous monitoring of vital signs. However, smart watches have been occupying a space in the portion of the population that practice physical activities with the aim of monitoring heart rate (HR) during their practice. Thus, this study infers about the use of smart watches as an instrument for measuring HR in hospitalized patients diagnosed with systemic arterial hypertension affected by covid-19. For this purpose, HR collection was carried out in 30 patients aged between 40 and 80 years old from male and female internships at Hospital de Campanha in Bacabal/MA, using a digital watch (Fitbit, charge HR) and a finger oximeter as a reference value. The devices (watch and oximeter) were placed on the left arm wrist and on the left index finger simultaneously during 30 minutes of evaluation in the patients. In addition to the HR collected by the devices, other vital signs were observed, such as blood pressure (sphygmomanometer), oxygen saturation (finger oximeter) and respiratory rate by analyzing the electrodes placed on the patients. ANOVA analyzes of variance were performed followed by Tukey's Comparison post-test and Pearson's correlation test with the aid of the GraphPadPrism version 7.0 software (GraphPad Software, San Diego, CA, USA). The results indicated that they were patients with a mean age for the male gender of 65.00 ± 15.39 years and for the female gender of 65.91 ± 23.06 years, with a respiratory rate per minute of 20.47 ± 0.5679 and 20.6 ± 0.3754 for males and females respectively, in addition to a similarity of 83.3% in HR measurements performed with the watch (84.9 ± 4.29 bpm) in relation to those with the oximeter (88.2 ± 3.75 bpm) with a Pearson correlation for r = 0.71. It can be concluded that the smart watch can be another instrument to be taken into account during the evaluation of vital signs with the same efficiency as that verified by the oximeter.Item Análises epidemiológica e espacial da Covid-19 no Estado do Piauí(Universidade Brasil, 2021) Macedo, Glauber Bezerra; Garcia, Lívia Assis; Tim, Carla RobertaThe emergence of a new coronavirus in humans, first diagnosed in 2019, has many deaths and serious survival and psychosocial consequences.
