ABSTRACT

BACKGROUND: Patients admitted with acute decompensated heart failure (HF) are subject to developing worsening episodes that require more complex interventions. The Acute Decompensated Heart Failure National Registry (ADHERE) risk model was developed in the United States to predict the risk of in-hospital worsening HF. OBJECTIVE: To use the ADHERE risk model in the assessment of risk of in-hospital worsening HF and to determine its sensitivity and specificity in hospitalized patients. METHODS: This cohort study was conducted at a Brazilian public university hospital, and data from 2013 to 2020 were retrospectively collected. P values < 0.05 were considered statistically significant. RESULTS: A total of 890 patients with a mean age of 74 ± 8 years were included. The model showed that, in the group of 490 patients at risk, 254 (51.8%) developed in-hospital worsening HF. In the group of 400 patients not at risk, only 109 (27.2%) experienced worsening HF. The results demonstrated a statistically significant curve (area under the curve = 0.665; standard error = 0.018; P < 0.01; confidence interval = 0.609 to 0.701), indicating good accuracy. The model had a sensitivity of 69.9% and a specificity of 55.2%, with a positive predictive value of 52% and a negative predictive value of 72.7%. CONCLUSIONS: In this cohort, we showed that the ADHERE risk model was able to discriminate patients who in fact developed worsening HF during the admission period, from those who did not.

Os resultados demonstraram uma curva estatisticamente significativa (área sob a curva = 0,665; erro padrão = 0,018; p < 0,01; intervalo de confiança = 0,609 a 0,701), indicando boa precisão. O modelo apresentou sensibilidade de 69,9% e especificidade de 55,2%, com valor preditivo positivo de 52% e valor preditivo negativo de 72,7%. CONCLUSÕES: Na presente coorte, demonstramos que o modelo de predição de risco ADHERE foi capaz de discriminar pacientes que, de fato, desenvolveram piora da IC durante o período de internação daqueles que não desenvolveram.

ABSTRACT

INTRODUCTION: The aim of this study was to evaluate the effectiveness of a diuretic adjustment algorithm (DAA) in maintaining clinical stability and reducing HF readmissions using telemonitoring technologies. METHODS: Randomized clinical trial of patients with an indication for furosemide dose adjustment during routine outpatient visits. In the intervention group (IG), the diuretic dose was adjusted according to the DAA and the patients received telephone calls for 30 days. In the control group (CG), the diuretic dose was adjusted by a physician at baseline only. Co-primary outcomes were hospital readmission and/or emergency department visits due to decompensated HF within 90 days, and a 2-point change in the Clinical Congestion Score and/or a deterioration in New York Heart Association functional class within 30 days. RESULTS: A total of 206 patients were included. Most patients were male (n=119; 58%), with a mean age of 62 (SD 13) years. Four patients (2%) in the IG and 14 (7%) in the CG were hospitalized for HF (odds ratio (OR) 0.31 (0.10-0.91); p=0.04). Multivariate analysis showed a reduction of 67% in readmissions and/or emergency department visits due to decompensated HF in the IG compared with the CG (95% CI 0.13-0.88; p=0.027). Regarding the combined outcome of HF readmission and/or emergency department visits or clinical instability, the IG had 20% fewer events than the CG within 30 days (IG: n=48 (23%), CG: n=70 (34%); OR 0.80 (0.63-0.93); p=0.03). DISCUSSION: Using DAA improved the combined outcome in these outpatients, with favorable and significant results that included a reduction in HF admissions and in clinical instability.

ABSTRACT

BACKGROUND: Caregivers can contribute enormously to the self-care of patients with heart failure (HF). The Caregiver Contribution to Self-care of Heart Failure Index (CC-SCHFI) measures these contributions across 3 scales: self-care maintenance, which evaluates caregiver contributions to symptom monitoring and treatment adherence; self-care management, which evaluates caregiver contributions in dealing with symptoms; and caregiver confidence, which assesses caregiver self-efficacy in managing all contributions to self-care. Although the CC-SCHFI has been used in several investigations, only 1 study has evaluated its psychometric characteristics. OBJECTIVE: The aim of this study was to evaluate the psychometric properties of the CC-SCHFI in Brazil. METHODS: A cross-sectional design was used in this study. Confirmatory factor analysis was used to assess construct validity, and factor score determinacy coefficients were computed to evaluate internal consistency reliability. RESULTS: The sample comprised 99 caregivers of patients with HF. Most were women (73%), with a mean age of 48 ± 14 years; 57% were patients' spouses. Confirmatory factor analysis confirmed the original factor structure of the instrument, with supportive fit indices for all 3 scales (comparative fit index, 0.95-1.00; root-mean-square error of approximation, 0.00-0.057). Reliability estimates were adequate for each CC-SCHFI scale (0.77-0.96). CONCLUSIONS: The CC-SCHFI is a valid and reliable scale to measure caregiver contributions to self-care maintenance, caregiver contributions to self-care management, and caregiver confidence in HF.

ABSTRACT

AIM: To analyze the behavior of B-type natriuretic peptide (BNP) in the presence of defining characteristics (DCs) of the nursing diagnosis Excess fluid volume (00026) in patients hospitalized for acute decompensated heart failure. METHODS: Cohort study of patients admitted with acute decompensated heart failure (September 2015 to September 2016) defined by Boston Criteria. Patients hospitalized for up to 36 h with BNP values ≥ 100 pg/ml were included; BNP values at baseline-final assessment were compared by Wilcoxon test, the number of DCs at baseline-final assessment was compared by paired t-test. RESULTS: Sixty-four patients were included; there was a significant positive correlation between delta of BNP and the number of DCs present at initial clinical assessment. CONCLUSIONS: The behavior of BNP was correlated to the DCs indicating congestion. With clinical compensation, DCs and BNP decreased. The use of this biomarker may provide additional precision to the nursing assessment.

ABSTRACT

AIMS AND OBJECTIVES: To test the validity and reliability of Nursing Outcomes Classification outcomes and their clinical indicators for patients with the nursing diagnosis 'Risk for perioperative positioning injury'. BACKGROUND: Surgical positioning is an essential part of perioperative nursing practice. The use of a standardised language values the clinical evaluation of the perioperative nurse, reinforcing its contribution to surgical patient care. DESIGN: Longitudinal concept validation cohort study. METHODS: Patients were selected based on the operating room surgical schedule. The sample included adult patients who underwent elective surgical procedures requiring anaesthesia, classified as surgical class 2, 3 or 4. Outcomes were measured with an instrument, which included 33 clinical indicators for eight outcomes. The patients were assessed at five distinct time points in the perioperative phases. This study followed the STROBE guidelines. RESULTS: A total of 50 patients were included. Each underwent five clinical assessments, for a total of 250 documented assessments. Differences in evaluations were mostly related to reduced scores of clinical indicators in the immediate postsurgical time points, which recovered to the highest score at the end of the fifth (and last) evaluation. The results of factor analysis and Cronbach's alpha calculations suggested a new configuration for this nursing outcomes, consisting of five outcomes-Circulation Status, Tissue Perfusion: peripheral, Neurological Status: peripheral, Tissue Integrity: skin and mucous membranes and Thermoregulation-and 13 clinical indicators. CONCLUSIONS: Nursing Outcomes Classification outcomes and clinical indicators for the nursing diagnosis at 'Risk for perioperative positioning injury' are sensitive to patient states during the perioperative period. RELEVANCE TO CLINICAL PRACTICE: Use of nursing taxonomies during the perioperative period may contribute to the discussion on the role of perioperative nurses and their relevance in patient care.

ABSTRACT

OBJECTIVES: To analyze the diagnostic accuracy in nursing in patients with predicted risk of clinical worsening during hospitalization for acutely decompensated heart failure. METHODS: Cohort study with data collection in medical records according to the Acute Decompensated Heart Failure National Registry risk model. After defining the patients at risk, the Nursing Diagnosis Accuracy Scale version 2 was applied. The scale classifies the accuracy as null, low, moderate or high. RESULTS: Of the 43 patients at risk of worsening, 22 (51%) did not worsen and 21 (49%) worsened; in both, the diagnostic accuracy was in the Moderate / High category in 22 (89%) and 16 (88%), respectively. Only Decreased cardiac output and Excessive fluid volume were scored with 100% in the High category. CONCLUSIONS: Patients with acute decompensated heart failure and risk of clinical worsening during hospitalization were identified with moderate or high diagnostic accuracy by nurses.

ABSTRACT

A ocorrência de quedas constitui uma das principais causas de morbidade e mortalidade na população idosa, tendo se tornado um problema importante de saúde pública devido aos altos custos sociais e financeiros que acarreta. O objetivo deste estudo foi determinar a prevalência de quedas em idosos vinculados a uma unidade básica de saúde. Trata-se de estudo descritivo transversal com a avaliação de idosos a partir de dois instrumentos: um relacionado aos dados sóciodemográficos e outro sobre a ocorrência de quedas nos últimos 12 meses. Os dados foram processados e analisados por meio do SPSS® versão 20.0 para Windows. No total, 97 idosos com média de idade de 70,5 anos (+ 8 anos) participaram do estudo 32 idosos referiram ter caído pelo menos uma vez nos últimos 12 meses, estimando prevalência de 33% (32/97; IC 95%: 24,2% - 42,8%) de quedas entre os participantes. O número de quedas variou de uma a 10 vezes no último ano, com média de duas quedas por idoso (+ 2 quedas). A queda da própria altura (87,5%) e ocorrida fora do domicílio (31,3%), foi a mais referida. O medo de cair novamente foi a consequência permanente da queda mais apontada pelos idosos. A prevalência de quedas neste estudo apresentou índices importantes, trazendo repercussões negativas para a saúde dos indivíduos.


Falls are the main causes of morbidity and death in elderly people. They are an important issue in public health due to high social and financial costs. Current descriptive and transversal analysis deals with the prevalence of falls in the elderly linked to a health unit. It also evaluates them through socio-demographic data and the occurrence of falls during the previous 12 months. Data were processed and analyzed by SPSS® 20,0 for Windows. Further, 97 elderly people, averaging 70,5 years (+ 8 years) participated, of whom 32 suffered at least one fall during the last 12 months, with a prevalence of 33% (32/97; IC 95%: 24,2% - 42,8%) among the participants. The number of falls ranged between one and 10 during the previous year, averaging two falls per elderly (+ 2 falls). Falls from one´s height (87,5%) and outside one´s home (31,3%) were the most common. Fear of falling once more was a permanent consequence indicated by the elderly. Prevalence of falls in current analysis showed important indexes with negative causes on individual health.

ABSTRACT

Visceral leishmaniasis is a severe form of the disease, caused by Leishmania infantum in the New World. Patients present an anergic immune response that favors parasite establishment and spreading through tissues like bone marrow and liver. On the other hand, Leishmania braziliensis causes localized cutaneous lesions, which can be self-healing in some individuals. Interactions between host and parasite are essential to understand disease pathogenesis and progression. In this context, dendritic cells (DCs) act as essential bridges that connect innate and adaptive immune responses. In this way, the aim of this study was to compare the effects of these two Leishmania species, in some aspects of human DCs' biology for better understanding of the evasion mechanisms of Leishmania from host innate immune response. To do so, DCs were obtained from monocytes from whole peripheral blood of healthy volunteer donors and from those infected with L. infantum or L. braziliensis for 24 h. We observed similar rates of infection (around 40%) as well as parasite burden for both Leishmania species. Concerning surface molecules, we observed that both parasites induced CD86 expression when DCs were infected for 24 h. On the other hand, we detected a lower surface expression of CD209 in the presence of both L. braziliensis and L. infantum, but only the last one promoted the survival of DCs after 24 h. Therefore, DCs infected by both Leishmania species showed a higher expression of CD86 and a decrease of CD209 expression, suggesting that both enter DCs through CD209 molecule. However, only L. infantum had the ability to inhibit DC apoptotic death, as an evasion mechanism that enables its spreading to organs like bone marrow and liver. Lastly, L. braziliensis was more silent parasite, once it did not inhibit DC apoptosis in our in vitro model.
