RESUMEN

BACKGROUND: The use of antiretrovirals has increased the survival of People Living with HIV/AIDS (PLWHA), resulting in an aging population and a rise in the incidence of sarcopenia. The lack of uniformity among the prevalences found in studies may be associated with the use of different diagnostic criteria, highlighting the need for local studies to determine the prevalence of sarcopenia. METHODS: Cross-sectional study to estimate the prevalence and associated factors of sarcopenia using the revised criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). This study included PLWHA of both sexes, aged 40 years or older, who were treated at the infectious disease outpatient clinic of a tertiary hospital from 2019 to 2021. Muscle mass was quantified through electrical bioimpedance, using resistance and reactance to calculate appendicular lean mass (ALM) in kg/m². Muscle strength, measured in kg, was assessed using a manual dynamometer, and muscle function was evaluated using the gait speed test (m/s). Numerical variables were analyzed using measures of central tendency and dispersion. The chi-square test was used to assess associations in categorical variables. Odds ratios (OR) and 95% Confidence Intervals (CI) were calculated to evaluate the strength of associations. RESULTS: Among the 218 PLWHA, the prevalence of sarcopenia was 8.7% (95% CI: 5.6 to 13.3). The mean age of the study population was 51.8 ± 8.3 years; 53.7% were male, 72.9% were brown/Black, 97.7% reported not using illicit drugs, and 24.8% were classified as obese. Multivariate analysis showed that the time since HIV diagnosis (P = 0.022) and the use of illicit drugs were associated with the diagnosis of sarcopenia. CONCLUSION: The prevalence of sarcopenia using the EWGSOP2 criteria was low. People with a longer duration of HIV infection and those using illicit drugs were more likely to develop sarcopenia.

RESUMEN

OBJECTIVE: To describe the feeding characteristics and growth of children with prenatal exposure to Zika virus (ZIKV) from birth to 48 months. DESIGN: Using data from the prospective Microcephaly Epidemic Research Group Pediatric Cohort (MERG-PC), children without microcephaly born to mothers with evidence of ZIKV infection during pregnancy (ZIKV-exposed children without microcephaly) and children with Zika-related microcephaly were compared using repeated cross-sectional analyses within the following age strata: birth; 1 to 12; 13 to 24; 25 to 36; and 37 to 48 months. The groups were compared in relation to prematurity, birth weight, breastfeeding, alternative feeding routes, dysphagia and anthropometric profiles based on the World Health Organization Anthro z-scores (weight-length/height, weight-age, length/height-age and BMI-age). RESULTS: The first assessment included 248 children, 77 (31.05%) with microcephaly and 171 (68.95%) without microcephaly. The final assessment was performed on 86 children. Prematurity was 2.35 times higher and low birth weight was 3.49 times higher in children with microcephaly. The frequency of breastfeeding was high (> 80%) in both groups. On discharge from the maternity hospital, the frequency of children requiring alternative feeding route in both groups was less than 5%. After 12 months of age, children with microcephaly required alternative feeding route more often than children without microcephaly. In children with microcephaly, the z-score of all growth indicators was lower than in children without microcephaly. CONCLUSIONS: Children with Zika-related microcephaly were more frequently premature and low birth weight and remained with nutritional parameters, i.e., weight-for-age, weight-for-length/height and length/height-for-age below those of the children without microcephaly.

RESUMEN

INTRODUCTION: Antiretroviral Therapy (ART) gives people living with HIV/AIDS (PLWHA) a new perspective of life, although some develop changes in impaired body composition. This study aimed to assess the factors associated with changes in body composition in PLWHA using ART, depending food consumption. MATERIAL AND METHODS: It was a cross-sectional study and took place through interviews with patients treated at an University Hospital. Secondary data: CD4+ T cells, ART time and age. The level of physical activity and smoking were self-reported. For the assessment of body composition, electrical bioimpedance and measurements of weight, height and waist circumference were used. RESULTS: The highest percentages of fat mass and fat-free mass, in treatment for more than 5 years, were in the female group (p <0.01), aged> 50 years (p = 0.02) and in the male group (p <0.01), young adult (p <0.01), respectively. The final linear regression model for both free fat mass and fat mass had sex, age, smoking and nutritional diagnosis as relevant factors. The frequency of food consumption was inadequate for calories, carbohydrates, proteins and lipids was high, however it did not significantly influence body composition. CONCLUSIONS: Gender, age, smoking and nutritional diagnosis by BMI significantly influence body composition.

RESUMEN

Severe brain damage associated with Zika-related microcephaly (ZRM) have been reported to result in oropharyngeal dysphagia (OPD); however, it is unknown if OPD presents in children with prenatal Zika virus (ZIKV) exposure but only mild or undetectable abnormalities. The aims of this study were: to compare the frequency and characteristics of OPD in children with ZRM and in children without microcephaly born to mothers who tested polymerase chain reaction positive (PCR+) for ZIKV during pregnancy; and to investigate the concordance of caregiver reports of OPD with the diagnosis from the clinical swallowing assessment (CSA). Between Mar/2017 and May/2018, we evaluated 116 children (n = 58 with microcephaly, n = 58 children without microcephaly born to ZIKV PCR + mothers) participating in the Microcephaly Epidemic Research Group (MERG) cohort of children born during the 2015-2016 ZIKV epidemic in Pernambuco, Brazil. To assess OPD we used: a CSA; a clinical assessment of the stomatognathic system; and a questionnaire administered to caregivers. The frequency of OPD was markedly higher in children with ZRM (79.3%) than in the exposed but normocephalic group (8.6%). The children with microcephaly also presented more frequently with anatomic and functional abnormalities in the stomatognathic system. There was a high degree of agreement between the caregiver reports of OPD and the CSA (κ = 0.92). In conclusion, our findings confirm that OPD is a feature of Congenital Zika Syndrome that primarily occurs in children with microcephaly and provide support for policies in which children are referred for rehabilitation with an OPD diagnosis based on caregiver report.

RESUMEN

BACKGROUND: Limb amputation can be defined as a procedure that consists of separating a limb or a segment of a limb from the body. OBJECTIVES: To describe the profile of limb amputation procedures performed at a large hospital run by the state of Pernambuco (Brazil). METHODS: Cross-sectional descriptive and retrospective study conducted at a large hospital in the city of Recife, PE. Data were collected from the records of patients who underwent amputations during 2017. Records from patients who had had a limb amputation during 2017 were included, unless data were illegible or missing. RESULTS: A total of 328 procedures were performed on 274 patients, the majority of whom were male (57.7%). There was a predominance of lower limb amputations (64.2%), of non-traumatic causes (86.5%), and urgent treatment (96.4%). The majority of patients who underwent amputations remained in hospital for 11 to 25 days (32.1%). The study found that the majority of amputees were discharged (69.7%), although a proportion died. Deaths of lower limb amputees were primarily among elderly women in the age range of 60 to 90 years (76%), females (55%), and patients subjected to a single amputation (91%). CONCLUSIONS: The data observed in this study are alarming, particularly considering that many of these amputations could have been avoided, since they were caused by complications of diseases that can be prevented and controlled at healthcare services of a lower level of complexity and at a relatively low cost.

RESUMEN

The aim of this study is to describe and relate nutritional and inflammatory status and prognostic indexes with postoperative complications and clinical outcome of patients with gastrointestinal malignancies. Twenty-nine patients were evaluated; nutritional assessment was carried out by subjective and objective parameters; albumin, pre-albumin, C-reactive protein (CRP), and alpha-1-acid glycoprotein (AGP) were determined. To assess prognosis, the Glasgow scale, the Prognostic Inflammatory Nutritional Index (PINI), and CRP/albumin ratio were used; the clinical outcomes considered were hospital discharge and death. A high Subjective Global Assessment (SGA) score was associated with the occurrence of postoperative complications: 73% of the patients with postoperative complications had the highest SGA score, but only 6% of those without postoperative complications had the highest SGA score (P < 0.001). Greater occurrence of death was observed in patients with a high SGA score, low serum albumin, increased CRP, PINI > 1, and Glasgow score 2. There was a positive correlation between weight loss percentage with serum CRP levels (P = 0.002), CRP/albumin (P = 0.002), PINI (P = 0.002), and Glasgow score (P = 0.000). This study provides evidence that the assessment of the nutritional status and the use of prognostic indexes are good tools for predicting postoperative complications and clinical outcome in patients with gastrointestinal neoplasia.

RESUMEN

BACKGROUND: The high-sensitivity C-reactive protein (hs-CRP) seems to be associated with the presence of atherosclerosis. The association between menopause-related changes in endogenous sex hormones and hs-CRP levels remains controversial. OBJECTIVE: To compare the levels of hs-CRP in pre- and postmenopausal women and to evaluate the association of endogenous sex hormones, waist circumference (WC) and insulin resistance with the levels of hs-CRP. METHODS: This cross-sectional study included 145 women (age range: 45-65 years), 56 premenopausal and 89 postmenopausal. Patients were evaluated for hormonal and lipid profile, HOMA-IR, hs-CRP and WC. Each variable was first assessed for correlation with log hs-CRP using a univariate model, and significant variables were then added to the multivariate regression model. A p value <0.05 was considered statistically significant. RESULTS: The hs-CRP is higher in postmenopausal patients (3.6 ± 4.9 versus 2.6 ± 3.7, p = 0.004). The log hs-CRP was positively correlated with WC (r = 0.13, p = 0.005), HOMA-IR (r = 0.29, p = 0.001), and triglycerides (r = 0.50, p = 0.01). The menopausal status (p = 0.02) and WC (p = 0.00003) behaved as independent predictors of hs-CRP levels. No correlation was found between hs-CRP and the time since menopause (r = -0.1, p = 0.58). CONCLUSIONS: The hs-CRP is higher in postmenopausal patients. The menopausal status and WC were independently associated with hs-CRP levels in this sample of pre and postmenopausal women.

RESUMEN

INTRODUCTION: The malnutrition-inflammation process is one of the main causes of morbidity and mortality in patients with chronic kidney disease (CKD), influencing quality of life. The aim of this study was to identify the inflammatory and nutritional status of elderly hemodialysis (HD) and its association with quality of life. METHODS: This study was carried out in health services in three different cities. The Malnutrition-Inflammation Score (MIS) was used to assess the inflammatory and nutritional status, with anthropometric measurements, protein status, lean mass and function. The quality of life was assessed using KDQOL-SFTM. Data were analyzed using multivariate analysis and the Poisson model to evaluate the factors that increased the risk of developing malnutrition and inflammation. RESULTS: The MIS identified a 52.2% prevalence of malnutrition and inflammation in the population. In univariate analysis, most KDQOL-SFTM domains presented higher scores for nourished elderly. Anthropometric measures associated with muscle mass and functionality were lower in the malnourished elderly. Multivariate modeling revealed a higher nutritional risk of 50.6% for women and older age, since with each additional year of life the risk of malnutrition increased by 2.4% and by 0.4% with each additional month on HD. Greater arm muscle circumference (AMC) and higher serum albumin were factors for reducing malnutrition by 4.6% and 34.7%, respectively. CONCLUSION: Higher serum albumin and preserved AMC have been shown to be good indicators of better nutritional status. Higher MIS was associated with poorer quality of life, older age, lower income and education, longer time on dialysis, and presence of comorbidities.

RESUMEN

BACKGROUND: Acute myocardial infarction is a major cause of mortality worldwide, and atherosclerotic plaque formation is the main pathophysiological mechanism, which results in chronic inflammation that induces erythrocyte maturation and may cause an increase in the red cell distribution width (RDW) index. OBJECTIVE: Evaluate the role of the anisocytosis index in patients with acute myocardial infarction in both types of infarctions as a predictor of severity. METHODS: Patients were included in the study according to the inclusion/exclusion criteria, following the hospital routine based on their clinical and laboratory history. Statistical analyzes were performed according to each variable. All conclusions were drawn considering the significance level of 5%. RESULTS: During the follow-up period, in the 349 patients analyzed, the mortality rate was associated with the variables RDW (CV) and RDW (SD), in those patients who died, an increase was noted, as demonstrated in the multivariate model, for the effects of an acute ST elevation myocardial infarction and the RDW, adjusted for confounding factors (p-value = 0.03 and 0.04). In contrast, the total number of erythrocytes (p-value = 0.00) and hemoglobin (p-value = 0.03) showed a decrease during severe patients' hospitalization. CONCLUSION: The anisocytosis index was a predictive factor of mortality and can be used as an indicator of worse prognosis in patients with acute myocardial infarction.


FUNDAMENTO: O infarto agudo do miocárdio é uma das principais causas de mortalidade em todo o mundo e a formação de placa aterosclerótica é o principal mecanismo fisiopatológico, que resulta em inflamação crônica e induz a maturação eritrocitária, podendo causar aumento no índice de amplitude de distribuição dos glóbulos vermelhos (RDW). OBJETIVO: Avaliar o papel do índice de anisocitose em pacientes com infarto agudo do miocárdio em ambos os tipos de infarto como preditor de gravidade. MÉTODOS: Os pacientes foram incluídos no estudo de acordo com os critérios de inclusão e exclusão, seguindo a rotina hospitalar baseada na história clínica e laboratorial. As análises estatísticas foram realizadas de acordo com cada variável. Chegou-se a todas as conclusões considerando o nível de significância de 5%. RESULTADOS: Durante o período de acompanhamento, nos 349 pacientes analisados, a taxa de mortalidade esteve associada às variáveis RDW (CV) e RDW (SD). Nos pacientes que foram a óbito, notou-se aumento, conforme demonstrado no modelo multivariado, nos efeitos de um infarto agudo do miocárdio com supradesnivelamento do segmento ST e RDW, ajustado para fatores de confusão (valor-p = 0,03 e 0,04). Em contrapartida, o número total de eritrócitos (valor-p = 0,00) e hemoglobina (valor-p = 0,03) apresentou diminuição durante a internação de pacientes graves. CONCLUSÃO: O índice de anisocitose foi fator preditivo de mortalidade e pode ser utilizado como indicador de pior prognóstico em pacientes com infarto agudo do miocárdio.

RESUMEN

OBJECTIVE: To assess the changes in body composition of burn patients through electrical bioimpedance in the phases of response to trauma. METHODS: a longitudinal observational study, carried out from October 2019 to March 2020. Sociodemographic, clinical, epidemiological, anthropometric and body composition data were collected. Statistical analysis was performed with SPSS, considering a significance of 5%. The comparison between variables was performed using the paired Student's t test. RESULTS: the sample consisted of 58 adult burn patients, with a mean age of 38.2±12.5 years. The mean body surface area (BSA) with burns was 10.8±7.3%. Nutritional assessment demonstrated a depletion of body weight, Body Mass Index, fat-free mass and muscle mass in the phases of response to trauma (p<0.005). CONCLUSION: metabolic alterations in the different phases of the metabolic response to trauma led to a depletion of the nutritional status of burn patients of both sexes during hospitalization.

RESUMEN

Studies investigating the association between the phase angle (PA) and frailty are scarce. The PA is considered a practical, low-cost, noninvasive measure for the early identification of this clinical condition. To investigate the association between PA and frailty/pre-frailty, nutritional and clinical aspects in older people. A cross-sectional study was conducted with 51 older people (≥ 60 years). PA was determined using bioelectrical impedance analysis. Frailty profile was determined using the criteria of unintentional weight loss, self-reported fatigue, slow gait speed, low grip strength and insufficient physical activity. Nutritional status was evaluated based on the body mass index and appendicular skeletal muscle mass index (ASMMI). Sarcopenia and sarcopenic obesity were also investigated. Sociodemographic data were collected through interviews. Prevalence of frailty/pre-frailty was 84.3%, with no difference between the sexes. The first tercile of the sample had a PA lower than 6º, which was considered low. No significant difference in PA was found between older people with or without frailty/pre-frailty. In the multiple linear regression analysis, age and ASMMI were shown to be potential independent predictors for PA. Age showed an inverse correlation with PA, while ASMMI showed a direct correlation. No association was found between PA and frailty or pre-frailty.

RESUMEN

PURPOSE: The objective of this study was to identify an association between serum levels of 25(OH) D, inflammation and cardiovascular disease risk in older adults. METHODS: This was a cross-sectional study, with older adults of both sexes, investigating variables on lifestyle, anthropometric assessments (weight, height, waist circumference, BMI), and systemic arterial hypertension (systolic blood pressure, SBP, and diastolic blood pressure DBP), serum levels of 25(OH)D, serum high-sensitive C-reactive protein (hs-CRP), serum lipid profile and fasting blood glucose. Cardiovascular disease risk was assessed using the global risk score for cardiovascular events, the Framingham criteria. RESULTS: The sample consisted of 124 participants, 50.8% of whom were at high risk for cardiovascular events. Older adults with 25(OH)D insufficiency presented higher levels of blood sugar (p < 0.01), LDL-c (p = 0.03) SBP (p < 0.01) and hs-CRP (p < 0.01). When grouped by serum concentrations hs-CRP, it was observed that higher hs-CRP levels were associated with higher blood glucose (p = 0.02), SBP (p = 0.04) and lower HDL-c concentrations (p = 0.02). It was also observed that 25(OH)D insufficiency increased the chance of a high risk for cardiovascular events by 2.8 times (OR = 2.80; p = 0.01), which with high hs-CRP concentrations increased to 4.75 times (OR = 4.75; p < 0.01). CONCLUSION: Low concentrations of 25(OH)D and the presence of inflammation in older adults are associated with a high risk for cardiovascular diseases.

RESUMEN

BACKGROUND: Omega-6 fatty acids are important to fetal development. However, during gestation/lactation, these fatty acids may contribute toward the development of fat tissue. Omega-9 fatty acids are associated with a reduction in serum lipids and protection from liver disease. OBJECTIVES: The present study investigated the effect of the maternal intake of omega-6 and omega-9 in hypercholesterolemic mothers on the liver of the offspring. METHODS: LDL receptor-deficient mice were fed a diet rich in either omega-6 (E6D) or omega-9 (E9D) for 45 days prior to mating and until the birth of the offspring, evaluating the effect on the offspring liver in comparison to a standard diet (STD). RESULTS: Mothers fed with the E6D experienced an increase in total cholesterol (TC) and the offspring exhibited an increase in TC, hepatic triglycerides (TG), and CC-chemokine ligand (CCL)2/monocyte chemoattractant protein (MCP)-1 as well as a reduction in HDL. Histological analysis on this group revealed steatosis, leukocyte infiltrate, and increased CCL2/MCP-1 expression. The ultrastructural analysis revealed hepatocytes with lipid droplets and myofibroblasts. The offspring of mothers fed the standard diet exhibited low serum TC, but microvesicular steatosis was observed. The offspring of mothers fed the E9D exhibited lower serum and hepatic TG as well as higher LDL in comparison to the other diets. The histological analyses revealed lower steatosis and leukocyte infiltrate. CONCLUSIONS: The findings suggest that hypercholesterolemic mothers with a diet rich in omega-6 fatty acids predispose their offspring to steatohepatitis, whereas a diet rich in omega-9 has a protective effect.

RESUMEN

BACKGROUND To determine the magnitude and temporal trends of deaths due to congenital heart disease (CHD) in Pernambuco between 1996 and 2016. METHODS This was an ecological, time-series study, involving all cases of deaths from congenital cardiovascular malformations in the state of Pernambuco, from 1996 to 2016, using data from DATASUS, SINASC and SIM. RESULTS There were 3,584 deaths from congenital cardiovascular malformations amongst individuals aged 0 to 14 years, of which 81.94% were concentrated in children aged under one year. The infant mortality rate (IMR) presented a linear growth trend of 0.4645 per year (p <0.01). The cause-of-death code Q24 (other congenital malformations of the heart) was present in 72.54% of the death records and 48.17% of the deaths occurred in infants aged between 28 and 364 days of life. The highest occurrence of deaths was identified in children with low birth weight (500 and 1,499g), male, premature, children of mothers without schooling, in deliveries at home (p <0.05). CONCLUSIONS Congenital heart disease still represents a public health problem as a cause of death, particularly in the first year of life, with IMR in a linear growth trend. Deaths from CHD were more prevalent in male children, born prematurely, with low birth weight, born to mothers with low schooling and deliveries without medical care.

RESUMEN

PURPOSE: The aim of this study was to verify if the association of hypertension and diabetes mellitus could lead to the differences on cardiorespiratory fitness and lipid profile in older adults. METHODS: 40 older adults were divided into two groups: Hypertensive (HTN) and Hypertensive-diabetic (HTN + T2DM). Maximum exercise test on a treadmill was conducted. Lipid profiles assessment was conducted before and after exercise. The cardiorespiratory fitness (CRF) variables were peak oxygen consumption (VO2peak), time to reach peak oxygen consumption (TVO2peak), carbon dioxide ventilatory equivalent (VE/VCO2) and carbon dioxide production (VCO2). To test intergroup and intragroup analyses independent and paired t-tests were used before and after acute exercise. Multiple linear regression was performed to test the influence of coexistence of HTN and T2DM on CRF. RESULTS: CRF measures such as VO2peak (ß = -3.90), VCO2 (ß = -3.87) and TVO2peak (ß= -115.79) were significantly (p-value <0.01) lower in HTN + T2DM group. After acute exercise, there was an increase in the levels of lipid profile variables, however without differences between groups. CONCLUSION: HTN + T2DM older adults had poorer CRF. Acute changes in lipemia were similar in both groups.

RESUMEN

BACKGROUND: Type 2 Diabetes Mellitus (T2DM) is common in older adults, who also present a high level of risk factors for cardiovascular disease (CVD), such as dyslipidemia. However, the role of depression in T2DM patients and its relationship with CVD risk factors are understudied. OBJECTIVE: The present study aimed to investigate the relationship between depressive symptoms (DS) and known cardiovascular risk factors in community dwelling older adults with T2DM. METHODS: This is a cross sectional study, in which 85 community-dwelling older adults with T2DM were assessed. DS was assessed using the Yesavage Geriatric Depression Scale - short version (GDS-15). The following cardiovascular risk factors were evaluated: systolic (SBP) and diastolic blood pressure (DBP), fasting plasma glucose (FPG), lipid profile (serum triglycerides - TG, serum total cholesterol - TC, serum low-density lipoprotein cholesterol - LDL-C, and serum high-density lipoprotein cholesterol - HDL-C) and body mass index (BMI). Poisson multiple regression was performed to test the association between DS and each cardiovascular risk factor adjusted by sex, age, time spent in moderate physical activity, and functional status. The significance level adopted for the analysis was 5%. RESULTS: Among all the analyzed risk factors, only high levels of LDL-C were related to high DS (PR=1.005, CI 95% 1.002-1.008). A significant association was observed between HDL-C levels (PR=0.99, CI 95% 0.98-0.99) and SBP (PR=1.009, CI 95% 1.004-1.014). CONCLUSION: In older adults with T2DM, the presence of DS was associated with LDL-C, HDL-C levels and SBP, even after adjusting for sex, age, physical activity level and functional capacity.

FUNDAMENTO: O Diabetes Mellitus Tipo 2 (DMT2) é comum nos idosos, que também apresentam um nível elevado de fatores de risco para doenças cardiovasculares (DCVs), tais como dislipidemia. Entretanto, o papel da depressão nos pacientes com DMT2 e sua relação com fatores de risco para DCV são pouco estudados. OBJETIVO: O objetivo do presente estudo foi investigar a relação entre sintomas depressivos (SDs) e fatores de risco cardiovascular conhecidos em idosos comunitários portadores de DMT2. MÉTODOS: Trata-se de um estudo transversal, no qual foram incluídos 85 idosos comunitários com DMT2. Os SDs foram avaliados através da Escala de Depressão Geriátrica de Yesavage, em versão reduzida (GDS-15). Os seguintes fatores de risco cardiovascular foram avaliados: pressão arterial sistólica (PAS) e diastólica (PAD), glicose plasmática em jejum (GPJ), perfil lipídico (triglicerídeos séricos (TG), colesterol total sérico (CT), colesterol sérico de lipoproteína de baixa densidade (LDL-C) e colesterol sérico de lipoproteína de baixa densidade (HDL-C)) e índice de massa corporal (IMC). A análise de regressão múltipla de Poisson foi utilizada para avaliar a associação entre os SDs e cada fator de risco cardiovascular ajustado por sexo, idade, tempo em atividades físicas moderadas e status funcional. O nível de significância adotado para a análise foi de 5%. RESULTADOS: Dentre todos os fatores de risco analisados, apenas o aumento de LDL-C apresentou uma correlação com níveis elevados de SD (RP=1,005; IC95% 1,002-1,008). Foi observada uma associação significativa entre os níveis de HDL-C (RP=0,99; IC95% 0,98-0,99) e a PAS (RP=1,009; IC95% 1,004-1,014). CONCLUSÃO: Nos idosos com DMT2, a presença de SD foi associada a níveis de LDL-C, HDL-C e PAS, mesmo após o ajuste por sexo, idade, nível de atividade física e capacidade funcional.

RESUMEN

ABSTRACT Objective: To assess the changes in body composition of burn patients through electrical bioimpedance in the phases of response to trauma. Methods: a longitudinal observational study, carried out from October 2019 to March 2020. Sociodemographic, clinical, epidemiological, anthropometric and body composition data were collected. Statistical analysis was performed with SPSS, considering a significance of 5%. The comparison between variables was performed using the paired Student's t test. Results: the sample consisted of 58 adult burn patients, with a mean age of 38.2±12.5 years. The mean body surface area (BSA) with burns was 10.8±7.3%. Nutritional assessment demonstrated a depletion of body weight, Body Mass Index, fat-free mass and muscle mass in the phases of response to trauma (p<0.005). Conclusion: metabolic alterations in the different phases of the metabolic response to trauma led to a depletion of the nutritional status of burn patients of both sexes during hospitalization.

RESUMEN

Resumo Fundamento O infarto agudo do miocárdio é uma das principais causas de mortalidade em todo o mundo e a formação de placa aterosclerótica é o principal mecanismo fisiopatológico, que resulta em inflamação crônica e induz a maturação eritrocitária, podendo causar aumento no índice de amplitude de distribuição dos glóbulos vermelhos (RDW). Objetivo Avaliar o papel do índice de anisocitose em pacientes com infarto agudo do miocárdio em ambos os tipos de infarto como preditor de gravidade. Métodos Os pacientes foram incluídos no estudo de acordo com os critérios de inclusão e exclusão, seguindo a rotina hospitalar baseada na história clínica e laboratorial. As análises estatísticas foram realizadas de acordo com cada variável. Chegou-se a todas as conclusões considerando o nível de significância de 5%. Resultados Durante o período de acompanhamento, nos 349 pacientes analisados, a taxa de mortalidade esteve associada às variáveis RDW (CV) e RDW (SD). Nos pacientes que foram a óbito, notou-se aumento, conforme demonstrado no modelo multivariado, nos efeitos de um infarto agudo do miocárdio com supradesnivelamento do segmento ST e RDW, ajustado para fatores de confusão (valor-p = 0,03 e 0,04). Em contrapartida, o número total de eritrócitos (valor-p = 0,00) e hemoglobina (valor-p = 0,03) apresentou diminuição durante a internação de pacientes graves. Conclusão O índice de anisocitose foi fator preditivo de mortalidade e pode ser utilizado como indicador de pior prognóstico em pacientes com infarto agudo do miocárdio.


Abstract Background Acute myocardial infarction is a major cause of mortality worldwide, and atherosclerotic plaque formation is the main pathophysiological mechanism, which results in chronic inflammation that induces erythrocyte maturation and may cause an increase in the red cell distribution width (RDW) index. Objective Evaluate the role of the anisocytosis index in patients with acute myocardial infarction in both types of infarctions as a predictor of severity. Methods Patients were included in the study according to the inclusion/exclusion criteria, following the hospital routine based on their clinical and laboratory history. Statistical analyzes were performed according to each variable. All conclusions were drawn considering the significance level of 5%. Results During the follow-up period, in the 349 patients analyzed, the mortality rate was associated with the variables RDW (CV) and RDW (SD), in those patients who died, an increase was noted, as demonstrated in the multivariate model, for the effects of an acute ST elevation myocardial infarction and the RDW, adjusted for confounding factors (p-value = 0.03 and 0.04). In contrast, the total number of erythrocytes (p-value = 0.00) and hemoglobin (p-value = 0.03) showed a decrease during severe patients' hospitalization. Conclusion The anisocytosis index was a predictive factor of mortality and can be used as an indicator of worse prognosis in patients with acute myocardial infarction.

RESUMEN

BACKGROUND: The intensity of the inflammatory response and hemodynamic repercussion in acute myocardial infarction causing the presence in the peripheral circulation of nucleated red blood cells (NRBCs), increases in mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR) are associated with a poorer prognosis. The aim of this study was to assess the role of these hematological biomarkers as predictors of all causes of mortality during the hospitalization of patients with acute myocardial infarction. METHODS: Nucleated red blood cells, mean platelet volume and neutrophil to lymphocyte ratio were measured daily during the hospitalization of the patients with acute myocardial infarction. We excluded patients younger than 18 years, on glucocorticoid therapy, with cancer or hematological diseases and those that were readmitted after hospital discharge. We performed a multiple logistic analysis to identify independent predictors of mortality. RESULTS: We included 466 patients (mean age 64.2 ± 12.8 years, 61.6% male). The prevalence of NRBCs in the sample was 9.1% (42 patients), with levels > 200/µL in 27 patients (5.8%). The mean MPV value was 10.9 ±0,9 and the mean NLR value was 3.71 (2,38; 5,72). In a multivariate analysis of serum NRBCs (HR 2.42, 95% CI: 1.35-4.36, p = 0.003), MPV (HR 2.97, 95% CI: 1.15-7.67, p = 0.024) and NLR (HR 5.02, 95% CI: 1.68-15.0, p = 0.004). The presence in the peripheral blood of NRBCs, increased in mean platelet volume and neutrophil to lymphocyte ratio were associated with higher mortality. CONCLUSIONS: Nucleated red blood cells, mean platelet volume and neutrophil to lymphocyte ratio are independent predictors of intrahospital mortality. Therefore, an important tool in intrahospital clinical surveillance.

RESUMEN

BACKGROUND: This study aimed to analyze the effect of a behavior change program, called Vida Ativa Melhorando a Saúde (VAMOS), on physical activity, eating habits, and quality of life in patients with hypertension. METHODS: A randomized controlled trial was carried out in 90 patients with hypertension (57.8 ± 9.9 y). They were randomly assigned to 2 groups: VAMOS group (n = 45) and control group (n = 45). The VAMOS group participated in a behavioral change program aimed at motivating changes in physical activity and nutrition behavior for 12 weeks. Physical activity, eating habits, quality of life, self-efficacy, and social support were evaluated at preintervention and postintervention. RESULTS: The control group increased sedentary time (407 ± 87 vs 303 ± 100 min/d; P < .05) and sedentary bouts (434 ± 86 vs 336 ± 98 min/d; P < .05) and reduced total physical activity (553 ± 87 vs 526 ± 86 min/d; P < .05). The VAMOS group improved the general healthy eating habits score (36.9 ± 6.6 vs 43.4 ± 5.8; P < .05) and quality of life (44% vs 92%; P < .05). CONCLUSION: The VAMOS program was effective in improving eating habits and quality of life in patients with hypertension.
