Effect of a Non-pharmacological Intervention on Vaccine-related Pain: Randomized Clinical Trial.

BACKGROUND: Acute pain during vaccine administration is an expected event; however, some strategies, such as the use of high frequency vibration devices associated with cryotherapy, may minimize it. AIM: Evaluate the effect of high frequency vibration associated with cryotherapy on the level of pain related to the administration of influenza vaccine by intramuscular route in adults. METHOD: A randomized clinical trial was conducted with 350 adults who received the influenza vaccine. Participants allocated to the intervention group used a high-frequency vibration device associated with cryotherapy during vaccination, and those in the control group administered the vaccine according to the service routine. RESULTS: Mean self-reported pain after vaccination of participants who used the device was lower (1.5 ±1.7) when compared to those who did not use it (1.9 ±1.9) (p = .041). There was an association of higher levels of pain after vaccination with participants in the control group (p = .011), females (p = .042), with higher level of pain expected with vaccination (p < .001) and higher level of anxiety before (p < .001) and after vaccination (p = .001). CONCLUSIONS: The use of high frequency vibration associated with cryotherapy has been shown to be a viable non-pharmacological intervention for the reduction of pain associated with influenza vaccination in adults.

Factors related to the self-application of insulin in subjects with diabetes mellitus. / Fatores relacionados à autoaplicação de insulina em indivíduos com diabetes mellitus.

OBJECTIVE: To identify the factors associated with the self-application of insulin in adult individuals with Diabetes Mellitus. METHOD: A cross-sectional study developed in the city of Viçosa-MG, which assessed 142 patients. The data collection was performed between April and July 2013 through an interview at the participant's home. Multiple logistic regression was used. RESULTS: The prevalence of the self-administration of insulin was of 67.6%, and it was associated with ages between 57 and 68 years old (OR = 0.3, 95% CI: 0.1-0.9), living with a partner and children (OR = 2.5, 95% CI: 1.1-5.0), 9 years or more of study (OR = 8.4, 95% CI: 1.9-37.9), living in an area not covered by the Family Health Strategy (FHS) (OR = 2.8, 95% CI: 1.1 - 7.0). CONCLUSION: The self-application of insulin was associated with age, schooling, marital status, and the FHS coverage. The recognition of these factors may contribute to the adherence to the self-application of insulin.

Hospitalizations and deaths of children and adolescents with Severe Acute Respiratory Infection due to COVID-19 during the epidemiological year of 2020.

This study aimed to analyze the profile of hospitalizations and factors associated with the deaths of children and adolescents with severe acute respiratory infection (SARI) caused by SARS-CoV-2 nationwide. The study comprised 6,843 children and adolescents hospitalized in 2020 who tested positive for COVID-19, based on data from the Influenza Epidemiological Surveillance Information System. Sociodemographic and clinical profiles, hospitalization frequency, lethality and recovery rates were analyzed. The outcome was recovery or death. The 6,843 children and adolescents comprised 1.9% of SARI hospitalized cases (n = 563,051). Of these, 57.7% developed critical SARI and 90% survived. Comorbidities were present in 40.8%, especially asthma, immunodepression, and neurological and cardiovascular diseases. The main symptoms were fever, cough, dyspnea, respiratory distress, and low oxygen saturation. Among those with critical SARI, 91.4% died. There was a higher frequency of children, especially those under five years of age and of mixed ethnicity. The highest hospitalization frequency occurred in the Southeastern and Northeastern regions, the highest recovery rates in the Southeastern and Southern regions, and the highest lethality rates in the Northern and Northeastern regions. Deaths were associated with ages ranging from 12 to 19 and being under one year of age, living in the Northern and Northeastern regions, progression to critical SARI, and having immunosuppression and cardiovascular disease. In contrast, asthma was associated with lower death rates. The frequency of complications and mortality rates caused by SARS-Cov-2 in the pediatric population are relevant, as well as the severity of the epidemic in the social inequality context and the health services' frailty.

Hypothermia among premature newborns on admission to a neonatal intensive care unit.

OBJECTIVE: To assess prevalence and factors associated with hypothermia in preterm infants admitted to a neonatal intensive care unit. METHODS: It is a cross-sectional retrospective study, with 154 premature newborns admitted between 2017 and 2019 in a neonatal intensive care unit. Logistic regression was used to evaluate the association to hypothermia. RESULTS: There was a predominance of males (55.8%), coming from the operating room (55.8%), gestational age > 32 weeks (71.4%), weight > 1500g (59.1%), Apgar in the 1st minute of life less than seven (51.9%) and in the 5th minute of life greater than or equal to seven (94.2%). The prevalence of hypothermia at admission was 68.2%. It was found that the lower the weight, the greater the chances of hypothermia, being three times higher in low weight (OR 3.480), five times higher in very low weight (OR5.845) and up to 47 times higher in extremely low weight (OR47.211). CONCLUSION: Hypothermia was 68.2% and it was associated with lower birth weight.

Factors associated with the lethality of patients hospitalized with severe acute respiratory syndrome due to COVID-19 in Brazil.

Due to the high rates of transmission and deaths due to COVID-19, understanding the factors associated with its occurrence, as well as monitoring and implementing control measures should be priority actions in health surveillance, highlighting the use of epidemiological surveillance information systems as an important ally. Thus, the objectives of this study were to calculate the mortality rate of hospitalized patients with severe acute respiratory syndrome due to COVID-19 and to identify factors associated with death, in the period corresponding to epidemiological weeks 01 to 53 of the year 2020. This was a longitudinal study, using the national influenza epidemiological surveillance information system database, routinely collected by healthcare services. The sociodemographic and clinical characteristics of 563,051 hospitalized patients with severe acute respiratory syndrome due to COVID-19 in the five regions of Brazil were analyzed. Cox regression was performed to assess factors associated with patient death during hospitalization. The national lethality rate was 35.7%, and the highest rates of lethality occurred in the Northeast (44.3%) and North (41.2%) regions. During the hospital stay, death was associated with older age (Hazard Ratio-HR = 1.026; p<0.001); male sex (HR = 1.052; p<0.001); living in the North (HR = 1.429; p<0.001), Northeast (HR = 1.271; p<0.001) or Southeast regions of Brazil (HR = 1.040; p<0.001), presenting any risk factor (HR = 1.129; p< 0.001), the use of invasive (HR = 2.865; p<0.001) or noninvasive (HR = 1.401; p<0.001) mechanical ventilation devices. A high case lethality rate was evidenced in patients with severe acute respiratory syndrome due to COVID-19, however, deaths were not evenly distributed across the country's regions, being heavily concentrated in the Northeast and North regions. Older male patients living in the North, Northeast, or Southeast regions of Brazil, who presented any risk factor and were submitted to the use of invasive or noninvasive mechanical ventilation devices, presented a higher risk of evolving to death.

Survival of patients with diabetes mellitus hospitalized for acute respiratory syndrome due to COVID-19.

Given the magnitude of COVID-19 and the increase in hospitalization cases for severe acute respiratory syndrome (SARS), especially among patients with diabetes mellitus, it is essential to understand the epidemiological aspects inherent to the disease and the worsening of cases. Thus, this study aimed to analyze the survival of patients with diabetes mellitus hospitalized for SARS due to COVID-19 in different regions of Brazil. This is a longitudinal study, carried out based on data reported in the Influenza Epidemiological Surveillance Information System during the year 2020. The number of patients with diabetes mellitus among the hospitalized cases of SARS due to COVID-19 in the different regions of Brazil and the lethality rate among them were identified. A comparison of patient profiles of those who survived or did not survive and the Cox regression analysis were performed to evaluate the factors associated with shorter survival of patients. It was found that 51.4% of patients hospitalized with SARS due to COVID-19 had diabetes, and the case lethality rate among them was 45.0%. The Northeastern and Northern regions presented a higher proportion of patients with diabetes mellitus (56.5% and 54.3%, respectively) and a higher lethality rate (53.8% and 59.9%, respectively). The mean survival time of cases with diabetes mellitus hospitalized for SARS due to COVID-19 was estimated to be 35.7 days (0.5 days). A lower survival rate was observed among residents of the Northeastern and Northern regions with skin color reported as non-white, who required admission to Intensive Care Units and invasive mechanical ventilation, and presented respiratory symptoms such as dyspnea, respiratory distress and an oxygen saturation lower than 95%. It is concluded that diabetes mellitus was responsible for the high occurrence and lethality, mainly in the Northeastern and Northern regions, among non-white patients and those with greater clinical severity, which reinforces the importance of taking measures aimed at supporting this population.

Effect of vibration associated with cryotherapy on vaccine-related pain and anxiety levels in adults: study protocol for a randomized clinical trial.

BACKGROUND: Vaccination is one of the most effective strategies for prevention and eradication of immunopreventable diseases, but community acceptance of vaccination can be influenced by different factors, such as pain and anxiety. The use of high-frequency vibration associated with cryotherapy has been used to manage pain and anxiety during the vaccination process in children, but studies with adults are still scarce. This study aims to evaluate the effect of high-frequency vibration associated with cryotherapy on the levels of self-reported pain and anxiety related to administration of the Influenza vaccine intramuscularly in adults. METHODS: A two-arm, parallel, randomized clinical trial conducted in a Brazilian Primary Health Care Unit is proposed. A sample of 350 adults will be randomly assigned to participate in the control group, receiving the vaccine intramuscularly according to the standard protocol of the service, or in the intervention group, receiving the vaccine by the same route and using a portable device of high frequency vibration associated with cryotherapy for 30 s before and during administration. The primary endpoints will be self-reported levels of pain, assessed before and after vaccine administration. Secondary endpoints will be levels of anxiety, satisfaction with vaccine administration, and discomfort caused by high frequency vibration and temperature of the frozen bag in contact with the skin. Self-reported levels of pain and anxiety will be compared before and after vaccination as well as between the control and intervention groups. DISCUSSION: By evaluating the effect of high-frequency vibration associated with cryotherapy on pain and anxiety levels, we expect to find evidence that will support nursing practice, in order to promote greater comfort and safety in the vaccination process and, consequently, greater compliance by the population, by minimizing its undesirable effects.

OBJECTIVE: To analyze the completeness of notifications of severe acute respiratory syndrome cases on the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) during the COVID-19 pandemic, on the national database and on the Regional Health Center database of the state of Minas Gerais, Brazil, in 2020. METHODS: This was a descriptive study of the completeness of sociodemographic variables and those related to etiology, clinical condition, evolution and diagnostic criteria of SIVEP-Gripe. The level of completeness was classified as excellent (> 95%), good (90% to 95%), regular (80% to 90%), poor (50% to 80%) or very poor (< 50%). RESULTS: The percentage of variables with excellent completeness was only 18.1% on the national database, and 27.8% on the regional database. CONCLUSION: Both SIVEP-Gripe databases presented low completeness, making it necessary to improve the work process and routine training of professionals aimed at the correct filling.

Factors associated with the incidence of pressure wounds in critical patients: a cohort study.

OBJECTIVES: to identify the incidence of pressure wound in critical patients and its associated factors. METHODS: retrospective cohort study, based on the analysis of 369 critical patients' records. Descriptive and inferential statistics were used, as well as logistic regression. RESULTS: the incidence of pressure wounds was 11.4%. Patients who had been hospitalized for four days or more (OR 2.99; CI95% 1.15-7.78), used nasoenteric tubes (OR: 3.81; CI95%: 1.4010.38), vesical drainage catheters (OR: 4.78; CI95%: 1.31-17.38) and tracheostomy (OR: 3.64; CI95%: 1.48-8.97) had a higher chance of developing pressure wounds. The mean score of the Braden scale among participants who developed (14.2 points) pressure wounds was statistically different (p<0.001) than that of those who did not (12.3 points). CONCLUSIONS: the incidence of pressure wounds was associated with a higher time in the unit, the use of nasoenteric tubes, vesical drainage catheters, and tracheostomies were associated with a higher time of hospitalization in the unit.

Hospitalizations and mortality by severe acute respiratory syndrome: comparison between the pre-pandemic and pandemic periods.

OBJECTIVE: To analyze the characteristics and the factors associated with mortality of cases hospitalized for severe acute respiratory syndrome in a health region, in pre-pandemic and pandemic periods. METHODS: A retrospective documentary study of epidemiological surveillance carried out with secondary data from the Influenza Epidemiological Surveillance Information System, regarding the cases of patients belonging to a health region of Minas Gerais, Brazil. RESULTS: During the pandemic period, there was an increase in the number of hospitalizations and deaths due to severe acute respiratory syndrome, in addition to differences between sociodemographic and clinical-epidemiological characteristics. In both periods, the age and the use of invasive ventilatory support were the predictors of hospital mortality. The mortality in the pandemic period was also associated with male gender, presence of risk factors, admission to an intensive care unit, use of non-invasive ventilatory support, and infection by COVID-19. CONCLUSIONS: In 2020, the detection rate of severe acute respiratory syndrome was 21 times higher than in 2019 and new symptoms, such as anosmia and ageusia, were included in their investigation. In both periods evaluated, elderly patients and patients on invasive mechanical ventilation had a higher risk of mortality. With the pandemic, there was a greater number of hospitalizations and factors associated with mortality.

Changes in body temperature of critically ill patients submitted to bed bathing: a crossover clinical trial.

OBJECTIVES: to compare tympanic and axillary body temperature values of critical patients before and after the traditional and dry bed bath. METHODS: this is a randomized, open crossover clinical trial conducted with 50 adult critical patients. All patients received both types of bed bathing. The tympanic and axillary temperature values were measured at the beginning and end of the baths. The Wilcoxon test or paired Student's t test was used. RESULTS: elderly and male patients predominated. There was no significant difference between tympanic temperature medians measured during the traditional bed bath (p=0.707) and dry bath (p=0.101). Axillary temperature means reduced at the end of the baths (p=0.001), being 36.12ºC in the traditional bath and 35.92ºC in dry bath. CONCLUSIONS: bed bath, regardless of the method used, caused a reduction in critical patients' axillary temperature.

OBJECTIVE: to analyze the sociodemographic and clinical profile of patients treated by the remote care service "Telessaúde-COVID" and the factors associated with positive results for COVID-19. METHODS: an exploratory and analytical study, carried out based on the analysis of patient records treated by a remote care service called "Telessaúde-COVID". Characteristics of the patients treated and variables related to the service's functioning were evaluated. A descriptive, inferential analysis was performed by logistic regression. RESULTS: 1,854 new patients were evaluated and an estimate of 8,630 visits. Female patients were predominant (60.9%), aged between 20 and 59 years (75.9%). The most frequent signs and symptoms were: headache (41.8%), cough (33.3%) and runny nose (30.0%). Of the total number of patients, 66.4% were reported as suspected case of COVID-19 and 14.5% tested positive for COVID-19. The age of 60 years or more was more common among confirmed cases (26.6%). Most patients (80.4%) did not require face-to-face assistance. Confirmed cases of COVID-19 were associated with the age of the patients (OR 1,020; IC95% 1,007 - 1,032); home contact with a confirmed/suspected case (OR 1,902; IC95% 1,178 - 3,070); presence of nausea/vomiting (OR 2,403; IC95% 1,148 - 5,029) and changes in smell (OR 2,827; IC95% 1,294 - 6,176). CONCLUSION: "Telessaúde-COVID" was relevant in the management and notification of cases, avoiding the search for face-to-face consultations without clinical indication. Among the suspected cases, positivity for COVID-19 was associated with aging, history of home contact, gastrointestinal and olfactory symptoms.

Effects of dry and traditional bed bathing on respiratory parameters: a randomized pilot study.

OBJECTIVE: to compare the time for performance of dry and traditional bed bathing and its effects on transcutaneous arterial oxygen saturation and respiratory rates in critical adult patients. METHOD: pilot study of a randomized, open, crossover clinical trial, performed with 15 adult critically ill patients. Each patient received a dry and a traditional bed bath. Analysis of variance with repeated measures was used, adopting p-value ≤ 0.05. RESULTS: most patients were male (73.3%), white (66.7%), with a mean age of 69.7 years. The dry bath was faster (20.0 minutes) than the traditional bath (30.0 minutes) (p<0.001). There was no significant difference between the patients' saturation means between baths (p=0.381), with 94.7% for the dry bath and 95.2% for the traditional bath. During the traditional bath, the patients' respiratory rate mean was higher (24.2 incursions per minute) and statistically different (p<0.001) from the value obtained for the dry bath (20.5 incursions per minute). CONCLUSION: the dry bath had a shorter duration than did the traditional bath, resulting in less patient exposure. The traditional bed bath had a negative effect on patients' respiratory rate, increasing it. Brazilian Registry of Clinical Trials (ReBEC): RBR-5qwkqd.

Evaluating the "satisfaction" and "self-confidence" in nursing students in undergoing simulated clinical experiences.

OBJECTIVE: To evaluate the "satisfaction" and "self-confidence" constructs in nursing students who underwent simulated clinical experiences in semiology and semiotechnique disciplines. METHOD: A descriptive study developed with Nursing students from a federal public university in the interior of Minas Gerais through weekly simulated workshops. The "satisfaction" and "self-confidence" constructs were evaluated by the "Student Satisfaction and Self-Confidence with Learning Scale" and "Simulated Clinical Experiences Satisfaction Scale". RESULTS: The final sample was 45 students. Most were more satisfied (overall average = 4.18) than self-confident (overall average = 4.12). The Spearman correlation test identified a significant and positive association between the "satisfaction" and "self-confidence" constructs. CONCLUSION: Students feel self-confident and satisfied with the use of simulation as an active teaching-learning methodology, highlighting that the higher the satisfaction level, the greater the student's self-confidence.

Resultados: ao comparar as respostas corretas antes e depois da intervenção, houve um aumento significativo em 75% das questões (p<0,05), incluindo aspectos teóricos e práticos da hipodermóclise. A pontuação média na autoavaliação dos alunos quanto à capacidade de explicar (0,9 versus 5,9 pontos) e realizar a hipodermóclise (1,9 versus 5,0) foi significativamente maior após a aplicação da metodologia de problematização (p<0,001). Conclusão: a metodologia de problematização teve um impacto positivo no conhecimento dos alunos sobre hipodermóclise. O número de respostas corretas após a intervenção educacional foi maior do que na avaliação inicial. A metodologia de problematização pode ser incorporada ao processo de ensino-aprendizagem de estudantes de enfermagem e medicina para o ensino de procedimentos como a hipodermóclise.
