Comparison between ultrasonography and computed tomography for measuring skeletal muscle mass in critically ill patients with different body mass index.

BACKGROUND & AIM: Among critical patients, there is an early onset of changes in both the quantity and quality of muscle mass. It is essential to find tools that promptly identify this muscle mass loss. The aim of this study was to compare the ultrasonography of the quadriceps femoris to the gold standard, thigh computed tomography (CT) for assessing the musculature of critically ill patients with different body mass index who have suffered traumatic brain injury. METHODS: This is a prospective validation study in an Intensive Care Unit (ICU) specialized in trauma care, located at a tertiary teaching hospital. Our study involved a convenience sample of patients. Sequential ultrasound and CT scans were performed at three distinct time intervals: upon admission, between 24 and 96 h' post-admission, and finally, between 96 and 168 h' post-admission. For all ultrasound measurements, we conducted simultaneous quadriceps CT measurements. The correlation between measurements obtained by ultrasound and computed tomography at three different times and in three BMI ranges was analyzed, in individuals with normal weight, overweight and obese. RESULTS: Results: We analyzed 252 images in 49 patients in time 1, 40 patients in time 2, and 37 in time 3 to compare the thickness quadriceps muscle using US and CT. Of these, 18 patients had a BMI ≤ 24.9 kg/m2 (normal weight), 18 patients from 25 to 29.9 kg/m2 (overweight), and 8 patients had a BMI ≥ 30 kg/m2 (obese). The mean age was 37 years, the majority (94%) were male and the main comorbidities were: hypertension 12%, diabetes 4% and 14% smoking. The results revealed minor discrepancies between measurements obtained through the two methods, these changes were not influenced by the body mass index, with these variations being practically insignificant in the context of clinical application. Thus, the correlation and concordance between the values obtained found a strong positive correlation with good limits of agreement. The Spearman's correlation coefficients obtained were r = 0.89, 0.91 and 0.88, p < 0.01 at T1, T2 and T3 respectively for normal weight, r = 0.91, 0.80 and 0.81, p < 0.01 at T1, T2 and T3 respectively for overweight and r = 0.89, 0.94 and 0.84, p < 0.01 at T1, T2 and T3 respectively for obesity. In addition to a positive correlation, we observed a high agreement between the methods. The Bland & Altman analysis at time 1 showed, respectively, the bias of 1.46, 2.03 and 0.76. At time 2, the bias was 0.42, 3.11 and 2.12. At time 3, the bias was 2.26, 3.38 and 2.11 mm. CONCLUSION: Our findings suggest that measure femoral quadriceps muscle thickness ultrasound-based exhibits a comparable performance to thigh CT. This conclusion stems from the excellent correlation and good agreement observed between ultrasound and CT, which is considered the gold standard for muscle assessment in critically ill patients.

Factors Associated with Late Diagnosis of Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) in a University Hospital in Brazil: Challenges to Achieving the 2030 Target.

INTRODUCTION: This study aimed to identify factors associated with late diagnosis and clinically monitor newly diagnosed HIV/AIDS patients. METHOD: Retrospective study, based on secondary data from a specialized unit at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto of the University of Sao Paulo. Data collection included sociodemographic, behavioral, clinical, and laboratory data of newly diagnosed HIV patients between 2015 and 2019. Data analysis was undertaken using inferential statistical tests. RESULTS: A total of 314 individuals were newly diagnosed with HIV/AIDS, 86.6% (272) had a late diagnosis and 53.8% (169) were diagnosed very late. Using the adjusted odds ratio, we observed that bisexual and MSM patients were less likely to have a late diagnosis compared to straight patients. Individuals who entered through the emergency department and Outpatient Clinic had a lower chance of having a very late diagnosis compared to those diagnosed in the ward/inpatient unit. Having a higher education and university education were protective factors against having a very late diagnosis of HIV infection compared to elementary school education only. In addition, male patients were more likely to have a very late diagnosis compared to female patients. CONCLUSIONS: This study evidenced a high prevalence of late and very late diagnoses. Therefore, attention should be directed towards factors related to late and very late presentation.

Effect of methylene blue on hemodynamic response in the early phase of septic shock: A case series.

RATIONALE: Methylene blue (MB) has been used to increase blood pressure in septic shock, acting on the activity of guanylate cyclase and nitric oxide synthase. PATIENCE CONCERNS: The aim of this study is to demonstrate the benefit of MB in early phase of septic shock.Diagnoses: We report 6 cases of patients with septic shock with up to 72 hours of evolution. INTERVENTIONS: We used MB after fluid replacement, use of norepinephrine and vasopressin. Patients received a loading dose of MB and maintenance for 48 hours. OUTCOMES: All patients presented a reduction in the dose of vasopressors and lactate levels soon after the administration of the loading dose of MB, an effect that was maintained with the maintenance dose for 48 hours. Interleukin 6 and interleukin 8 were elevated at the beginning of the septic condition, with a progressive and marked reduction after the beginning of MB infusion, demonstrating a role of MB in reducing the inflammatory activity. LESSONS: This case series suggests that MB used early in the treatment of septic shock may be useful in reducing vasopressor dose and lactate levels. Further studies are still required to further validate these findings.

Interprofessional education in Brazilian nursing undergraduate course syllabi.

The objective of this study was to analyze aspects related to interprofessional education in healthcare through the assessment of the syllabi of undergraduate nursing programs in Brazil. An observational, descriptive study was conducted in two phases. The first phase involved identification of programs, and the second phase involved documental analysis of the syllabi through a script created for this purpose. One thousand two hundred and twenty nursing undergraduate programs were identified; 229 were included in the sample for the document analysis. In 2.6% of the programs, the term "interprofessional" was identified in the purpose of the programs. Seventeen percent of the programs valued interprofessional education, and 8% assessed interprofessional learning. Recognizing (9.2%) and respecting (6.6%) the attributes and roles of different professionals were the least identified interprofessional values in the syllabi. Interprofessional education was not institutionalized/stated in the documents, even though the documents indicated use of interprofessional relationships in training scenarios, especially in primary care, and in activities not included in the formal curriculum.

Comparison of ultrasound with computed tomography to measure skeletal muscle mass in critically ill patients: A prospective study protocol.

INTRODUCTION: Therapy and nutritional status directly interfere in the clinical evolution of critically ill patients, in reducing morbidity and mortality, by maintaining the functional integrity of the gastrointestinal tract, decreasing the catabolic response, besides contributing to the reduction of hospitalization time resulting in less treatment cost. Critical patients and trauma victims suffer early changes in the quantity and quality of muscle mass. Tools to identify the groups most susceptible to these complications are necessary so that interventions can minimize the deleterious effects of malnutrition in critically ill patients. METHODS AND ANALYSIS: The aim of the present study is to measure muscle mass loss by measuring the thickness of the rectus femoris muscle by bedside ultrasound in critically ill patients admitted to the Intensive Care Unit (ICU) of a university hospital. Information will be collected regarding the length of hospital and ICU stay, the reason for admission, anthropometric data at admission and during hospitalization, energy needs, nutritional therapy used, and fasting time. This is a prospective, observational study that will be carried out in a single center in an ICU of a tertiary university hospital. The study population will undergo 3 tomographic images and 3 ultrasounds of the rectus femoris of each patient at different times. We propose, unprecedentedly, performing a validation study of ultrasound with the gold standard Computed tomography to evaluate the musculature of critically ill patients victims of traumatic brain injury. The results got will texto be fundamental for the development of new fields of investigation and certainly contribute to the discovery of a new approach to treat sarcopenia in critically ill patients. The Research Ethics Committee approved the study and all patients included will sign an informed consent form. (Clinical Record: RBR-2bzspnz).

Reactive treponemal and non-treponemal tests in pregnant women and associated factors.

OBJECTIVE: to identify the rate of reactive treponemal and non-treponemal tests in pregnant women during childbirth and to analyze the factors associated with this seroreactivity. METHOD: this is a cross-sectional, quantitative study with secondary sources of sociodemographic and clinical data on 2,626 pregnant women treated at a public maternity hospital in the interior of São Paulo, in 2020. For statistical analysis, Fisher's exact test, Mann-Whitney test and the logistic regression model were used. A difference of p < 0.05 was considered statistically significant. RESULTS: the rate of seropositivity for syphilis among pregnant women in this series was 2.74%. Among the groups with positive and non-reactive tests, marital status, occupation, place of residence and use of licit drugs indicated significant differences, but, in the final model, only unmarried marital status was associated with reactive tests (Odds Ratio: 0.169; Confidence Interval: 0.04-0.72; and p: 0.016). CONCLUSION: in this study, unmarried marital status was the only independent factor associated with seroreactivity for syphilis. Therefore, it is necessary to create strategies aimed at women in this condition, potentially reducing the rate of congenital syphilis.

Increased use of psychoactive substances among Brazilian health care professionals during the COVID-19 pandemic.

This study aimed to estimate the prevalence of increased psychoactive substance use (PSU) and associated factors among health care professionals. A cross-sectional and analytical study with 12,086 Brazilian health professionals was undertaken. An online questionnaire was used to gather data concerning sociodemographic factors, increased consumption of alcoholic beverages, tobacco, and hypnotics or sedatives during the COVID-19 pandemic. The prevalence of tobacco, alcoholic beverages, and hypnotic or sedative consumption were 17.8 %, 69.0 % and 17.1 %, respectively. Regression analyses indicated that having no religion and social isolation were associated with increased PASU during the pandemic. COVID-19 pandemic stressors may increase PASU, and increased PASU may increase the risk of substance use disorders and substance use-related chronic diseases, such as cancer.

METHODS: an integrative review, carried out in the LILACS, CINAHL, Web of Science, Scopus, PubMed and EMBASE databases, with controlled descriptors therapeutic and prenatal syphilis. RESULTS: nine publications composed the interpretative analysis, in which low education, income and maternal age, temporary lack of medication and HIV infection were associated with inadequate treatment of syphilis during pregnancy, in addition to delay or absence of prenatal care and receiving the 1st dose of penicillin, lack of tests or treatment less than 30 days before childbirth, and partners' low compliance with treatment. FINAL CONSIDERATIONS: among the main factors associated with inadequate treatment, clinical and sociodemographic aspects stand out, as well as failures in drug dispensing, prescription and monitoring of treatment of pregnant women and their partners by the health system.

Use of recommended personal protective equipment among Brazilian health professionals during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic is one of the biggest health crises in the world and the use of personal protective equipment (PPE) is significant measures to prevent the transmission of SARS-CoV-2. However, PPE needs to be used properly by healthcare professionals. OBJECTIVE: To analyze the use of PPE among Brazilian health professionals and associated factors during a period of the COVID-19 pandemic. METHODS: An analytical cross-sectional study was carried out from October to December 2020. For data collection, the respondent-driven sampling technique was used, adapted for social media, with a link to an online survey form. RESULTS: The study considered 12,086 Brazilian health professionals. Most (69%) used PPE recommended for the care of patients with suspected or diagnosed COVID-19. Factors associated with the use of PPE were: working in an Intensive Care Unit (ICU) or in a field hospital, receiving training, being provided with sufficient, high-quality PPE by the workplace and being an odontologist compared to nursing professionals. For procedures that generate aerosols in the context of COVID-19, 54.1% of them used the recommended PPE, the associated factors were: being married or in a stable relationship compared to a single/divorced professional, working in an ICU, being offered training, providing sufficient, high-quality PPE, and being an odontologist compared to nursing professionals. CONCLUSIONS: For the care of patients with COVID-19, 69% of health professionals used PPE properly, and several factors interfered with the use of this equipment.

Timeline Kinetics of Systemic and Airway Immune Mediator Storm for Comprehensive Analysis of Disease Outcome in Critically Ill COVID-19 Patients.

In the present study, the levels of serum and airway soluble chemokines, pro-inflammatory/regulatory cytokines, and growth factors were quantified in critically ill COVID-19 patients (total n=286) at distinct time points (D0, D2-6, D7, D8-13 and D>14-36) upon Intensive Care Unit (ICU) admission. Augmented levels of soluble mediators were observed in serum from COVID-19 patients who progress to death. An opposite profile was observed in tracheal aspirate samples, indicating that systemic and airway microenvironment diverge in their inflammatory milieu. While a bimodal distribution was observed in the serum samples, a unimodal peak around D7 was found for most soluble mediators in tracheal aspirate samples. Systems biology tools further demonstrated that COVID-19 display distinct eccentric soluble mediator networks as compared to controls, with opposite profiles in serum and tracheal aspirates. Regardless the systemic-compartmentalized microenvironment, networks from patients progressing to death were linked to a pro-inflammatory/growth factor-rich, highly integrated center. Conversely, patients evolving to discharge exhibited networks of weak central architecture, with lower number of neighborhood connections and clusters of pro-inflammatory and regulatory cytokines. All in all, this investigation with robust sample size landed a comprehensive snapshot of the systemic and local divergencies composed of distinct immune responses driven by SARS-CoV-2 early on severe COVID-19.

Factors associated with the diagnosis of COVID-19 among Brazilian health professionals COVID-19 and health professionals.

INTRODUCTION: Health professionals are on the front lines against the Coronavirus 2019 (COVID-19) pandemic and are at high risk for acquiring the infection. Failures in precautionary measures, inadequacy/scarcity of Personal Protective Equipment (PPE), and lack of social and family distancing may be associated with increased exposure and contamination by the new coronavirus. This study investigated the prevalence of COVID-19 among Brazilian health professionals and associated factors according to demographic and occupational characteristics. METHODS: A cross-sectional, analytical study was conducted using an online survey with 12,086 health professionals from all regions of Brazil. Data were collected using an adaptation of the respondent-driven sampling method for the virtual environment. The outcome variable was the diagnosis of COVID-19. Bivariate and multiple logistic regression analyzes were used to identify an association between the diagnosis of COVID-19 and demographic and occupational variables. Variables were considered statistically significant based on p<0.05. RESULTS: Most participants were female, from the northeast region, and nursing professionals. A prevalence of 31.95% (95%CI: 31.0%, 32.9%) of COVID-19 was estimated. Following multiple regression analysis, the variables associated with the diagnosis of COVID-19 among health professionals were: male gender, married individuals, professionals who provide care to patients with COVID-19, who work in a field hospital, and those who work in institutions that did not offer enough quality PPE. CONCLUSIONS: The study found a high prevalence of COVID-19 infection, with male professionals being those with greater chances. Inadequate supply or poor quality of PPE offered by health institutions compromises the health of professionals with an increase in positive diagnosis for COVID-19.

Comparing surgeons' skin tolerance and acceptability to alcohol-based surgical hand preparation vs traditional surgical scrub: A matched quasi-experimental study.

BACKGROUND: We aimed to compare the tolerance and acceptability of alcohol-based surgical hand preparation versus handscrubbing with antimicrobial soap and water by surgeons. METHODS: Matched quasi-experimental trial in an academic quaternary care hospital in Ribeirão Preto, Brazil, from April 1 to October, 31, 2017. Participants were cardiac and orthopedics surgeons from the study facility. In the first study phase, they performed handscrubbing with either 2% chlorhexidine (CHG) or 10% iodopovidone (PVP-I) and, in the second phase, they performed handrubbing with alcohol-based handrub (ABHR). Surgeons' skin tolerance and acceptability were evaluated using WHO-validated tools. Data were analyzed using the MacNemar's test within STATA. RESULTS: A total of 33 surgeons participated to the "per protocol" population; the majority were male (94%); mean age of 35 years (SD, 8.5). On product tolerance, there was a minimal variation in redness, scaliness, fissures, and visual evaluation of the skin when handrubbing with ABHR was compared to handscrubbing with either PVP-I or CHX. Regarding acceptability, participants rated better handrubbing with ABHR than handscrubbing with PVP-I when assessing product smell (66.6% vs 0%, p=0.002), color (73.3% vs 0%, p=0.001), product texture (60% vs 0%, p=0.004), skin dryness (60% vs 0%, p=0.004), ease of application (66.6% vs 0%, p=0.002) and overall satisfaction (66.6% vs 6.7% p=0.011). Participants rated similarly handrubbing with ABHR and handscrubbing with CHX, except for product texture, where handrubbing rated better (71,4% vs. 0%, p=0.002). Handrubbing with ABHR was preferred by 73.3%. CONCLUSION: Although handrubbing and handscrubbing were equally well tolerated by surgeons, alcohol-based surgical hand preparation fell into the personal preference for most of them.

Impact of a dental care intervention on the hospital mortality of critically ill patients admitted to intensive care units: A quasi-experimental study.

BACKGROUND: We aimed to evaluate the impact of providing dental care to critically ill patients on their risk of death and ventilator-associated pneumonia (VAP). METHODS: A quasi-experimental study was conducted in 2 intensive care units (ICU) from 2016 to 2019. The intervention consisted of implementing routine dental care, focusing on oral hygiene and periodontal treatment, at least 3 times a week, for patients admitted to the study units. In the pre-intervention period, routine oral hygiene was provided by the ICU nursing staff. The primary and secondary study outcomes were mortality, evaluated at the end of the ICU stay, and VAP incidence density, respectively. Data were analyzed using the ARIMA (autoregressive integrated moving average) time series model in R software. RESULTS: During the intervention period, 5,147 dental procedures were performed among 355 patients. The time series showed that ICU mortality was 36.11%, 32.71%, and 32.30% within the 3 years before the intervention, and 28.71% during the intervention period (P = .015). VAP incidence density did not significantly change during the study period (P = .716). CONCLUSION: A dental care intervention focused on oral hygiene and periodontal treatment regularly provided by dentists to critically ill patients may decrease their risk of dying in the ICU. Randomized clinical trials should be performed to confirm these findings. TRIAL REGISTRATION: WHO-affiliated Brazilian Clinical Trials Registry. RBR-4jmz36.
