Correlation of sleep quality and cardiac autonomic modulation in hemodialysis patients.

Objectives: Sleep disorders in patients on hemodialysis are frequent, but few studies correlate these disorders with autonomic dysfunction in these patients. This study aimed to verify whether clinical and laboratory variables and heart rate variability are associated with worse sleep quality verified by the Pittsburg subjective scale in patients on hemodialysis. Material and Methods: A cross-sectional study was performed on forty-eight patients. Epidemiological, clinical, and laboratory data were collected. After were performed by recording the heart rate variability and applied Pittsburg questionnaires, Beck anxiety index (BAI), and Beck depression index (BDI). The global PSQI score >5 indicates that a person is a poor sleeper, the patients were divided according to the scores in the Pittsburg questionnaire into good and poor sleepers and the differences between all variables were analyzed. Results: Forty-eight patients were evaluated and the prevalence of 68.7% (n=33) of poor sleep quality was verified. From the depression and anxiety questionnaires, it was found that only 18.7% (n=9) had criteria for depression. In the analysis of the sympathetic dysfunction parameters, it was found that in the group with good sleep quality in the frequency domain (HFm2) and the LFnu in the group with worse sleep quality. There was a positive correlation between sleep quality scores the anxiety and depression scores. It is also verified that the variables LFnu had a positive correlation with higher scores of quality of sleep and HFnu had a negative correlation with the highest scores of quality of sleep. Conclusion: In patients undergoing hemodialysis, the poorest quality of sleep is correlated with worse cardiac autonomic modulation as well as higher scores on the depression and anxiety scales.

Development and validation of a simple web-based tool for early prediction of COVID-19-associated death in kidney transplant recipients.

This analysis, using data from the Brazilian kidney transplant (KT) COVID-19 study, seeks to develop a prediction score to assist in COVID-19 risk stratification in KT recipients. In this study, 1379 patients (35 sites) were enrolled, and a machine learning approach was used to fit models in a derivation cohort. A reduced Elastic Net model was selected, and the accuracy to predict the 28-day fatality after the COVID-19 diagnosis, assessed by the area under the ROC curve (AUC-ROC), was confirmed in a validation cohort. The better calibration values were used to build the applicable ImAgeS score. The 28-day fatality rate was 17% (n = 235), which was associated with increasing age, hypertension and cardiovascular disease, higher body mass index, dyspnea, and use of mycophenolate acid or azathioprine. Higher kidney graft function, longer time of symptoms until COVID-19 diagnosis, presence of anosmia or coryza, and use of mTOR inhibitor were associated with reduced risk of death. The coefficients of the best model were used to build the predictive score, which achieved an AUC-ROC of 0.767 (95% CI 0.698-0.834) in the validation cohort. In conclusion, the easily applicable predictive model could assist health care practitioners in identifying non-hospitalized kidney transplant patients that may require more intensive monitoring.

Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in Nondialysis Chronic Kidney Patients.

BACKGROUND: The Neutrophil-to-Lymphocyte Ratio (NLR) and the Platelet-to-Lymphocyte Ratio (PLR) are inflammatory biomarkers for several diseases, such as cancer and cardiovascular morbidities; however, there are currently few studies on kidney diseases. We aimed to evaluate nondialysis patients and determine the association of NLR and PLR with inflammation in these patients. METHODS: A prospective cross-sectional study was conducted with 85 patients at different stages of chronic kidney disease (CKD), treated at the Kidney Disease Prevention Center of the University Hospital of the Federal University of Maranhão. This study included adult nondialysis patients diagnosed with CKD. The participants' blood samples were collected for a high-sensitivity C-reactive protein (hs-CRP) test and blood count. They were divided into two groups according to the presence or absence of inflammation based on the hs-CRP value (<0.5 mg/dL). NLR and PLR were calculated based on the absolute number of neutrophils, lymphocytes, and platelets and were compared between them and with hs-CRP. Statistical analysis was performed using the Stata software, with the Shapiro-Wilk, Mann-Whitney, Spearman's Correlation, and receiver operating characteristic curve tests. This study was approved by the local ethics committee. RESULTS: The participants were categorized into two groups: with inflammation (n = 64) and without inflammation (n = 21). The mean age was 61.43 ± 14.63 y. The NLR and PLR values were significantly different between the groups with and without inflammation (p=0.045and p=0.004, respectively). However, only PLR showed a significant positive correlation with hs-CRP (p=0.015). The best cutoff point for NLR to detect inflammation was 1.98, with 76.19% sensitivity and 48.44% specificity. For PLR, it was 116.07, with 85.71% sensitivity and 51.56% specificity. There was no significant difference between the area under the NLR and PLR curve (0.71 vs. 0.64; p=0.186) for this population. CONCLUSIONS: This study showed that PLR was positively correlated with hs-CRP in nondialysis CKD patients and can be used to identify inflammation in this population.

Variability in Hemoglobin Levels and the Factors Associated with Mortality in Hemodialysis Patients: A 78-Month Follow-Up Study.

Some studies have described that when the hemoglobin levels of chronic kidney disease (CKD) patients change, especially in those taking erythropoiesis-stimulating agents (ESA), they are associated with unfavorable outcomes such as increased morbidity and mortality, mainly due to cardiovascular events. This prospective cohort study included patients with end-stage renal disease currently undergoing hemodialysis. The initial 6-month clinical evaluation provided data of the variability in hemoglobin, associated blood parameters, and the use of erythropoietin. Subsequently, the patients were followed up for 78 months to evaluate mortality-associated factors. In total, 133 patients completed the 6-month follow-up with a mean age of 47.1 (±13.2) years. The majority were women (51.9%). Six-month hemoglobin levels were as follows: always low (18.0%), intermediate/target (1.5%), always high (0.8%), low-amplitude fluctuation/Hb low (n = 37; 27.8%), low-amplitude fluctuation/Hb high (13.53%), and high-amplitude fluctuation (38.6%), among end-stage renal disease patients. At the end of 78 months, 50 (37.6%) patients died; 70% of deaths were attributed to cardiovascular etiologies. A high variability was observed in hemoglobin levels, which was not associated with mortality. Among all the variables evaluated, age, erythropoietin dose, and transferrin saturation were associated with a higher mortality. Thus, this study suggests that greater attention to erythropoietin doses and transferrin saturation levels may improve the survival of dialysis patients.

In vitro comparison of peracetic acid and autoclave sterilization in the corrosion of orthodontic pliers: a pilot study.

INTRODUCTION: The most currently recommended method for sterilization of orthodontic pliers is the autoclave, while peracetic acid has also been shown to be effective in the chemical sterilization process. OBJECTIVE: This study sought to compare the corrosive effects of peracetic acid and autoclave sterilization process of orthodontic pliers. METHODS: Four active tungsten carbide (WC) stainless steel tie-cutting pliers from the manufacturers Quinelato (Rio Claro, SP, Brazil) and ICE (Cajamar, SP, Brazil) were selected. The active ends of the pliers were sectioned, and six active tips were obtained and distributed into the following groups: 1) control group (no sterilization); 2) AC group (two active pliers tips submitted to 100 autoclave sterilization cycles); and 3) AP group (two active pliers tips submitted to 100 cycles of sterilization by immersion in 2% peracetic acid solution for 30 minutes). RESULTS: Chemical analysis using X-ray dispersive energy spectroscopy showed that after autoclave sterilization, only the ICE pliers presented oxidation corrosion (Δ[O] = +24.5%; Δ[Fe] = +5.8%; Δ[WC] = -1.9%). In comparison, following peracetic acid sterilization, both manufacturers ICE (Δ[O] = +1.8%; Δ[Fe] = +18.0%; Δ[WC] = -1.1%) and Quinelato (Δ[O] = +5.3%; Δ[Fe] = -10.4%; Δ[WC] = -15.2%) showed corrosion. The morphological analysis revealed that peracetic acid caused a pitting and localized corrosion in both brands, while the autoclave caused uniform surface corrosion on the ICE pliers. CONCLUSION: Autoclave application was the sterilization method that generated less corrosive damage to the orthodontic cutting pliers, when compared to the immersion in 2% peracetic acid.

Efeito do treinamento aeróbio em parâmetros cardiorrespiratórios, hemodinâmicos e autonômicos de pacientes com doença renal crônica em hemodiálise / Effect of aerobic training on cardiorespiratory, hemodynamic, and autonomic parameters of chronic kidney disease patients on hemodialysis

A doença renal crônica (DRC) é uma condição clínica de alto risco cardiovascular e os pacientes nos estágios mais avançados da doença que dependem de terapia renal substitutiva frequentemente tem prejuízo cardiorespiratório, níveis elevados de pressão arterial (uso de múltiplas medicações para controle), modulação autonômica prejudicada e graus variados de inflamação. Deste modo este estudo tem como objetivo verificar se o exercício físico aeróbio intradialítico tem impacto em modificar estas alterações. Os pacientes foram selecionados em duas unidades de hemodiálise em São Luís do Maranhão, Brasil, entre junho de 2016 e outubro de 2019, e foram alocados conforme aceitação em grupo controle (GC) e grupo exercício (GE). O GE foi submetido a treinamento aeróbio com bicicleta por um período de 12 semanas. Avaliação física antropométrica, teste de caminhada de 6 minutos (TC6m), ecocardiograma, eletrocardiograma com análise da variabilidade da frequência cardíaca e medidas laboratoriais foram realizadas incluindo interleucina 6 (IL6) antes e após 12 semanas em ambos os grupos. Trinta e um pacientes foram avaliados 15 pacientes no grupo controle (GC) e 16 pacientes no grupo exercício (GE). Após 12 semanas de treinamento houve diminuição da pressão arterial sistólica do grupo exercício em relação ao basal (129,8 ± 9,41mmHg vs 112,00 ± 12,0 mmHg p = 0,03). Não houve alterações na composição corporal e na maioria dos exames laboratoriais, exceto pelo aumento do KTV (índice de adequação de diálise) e diminuição do LDL colesterol no grupo exercício em relação ao grupo controle. No entanto, os níveis de HDL colesterol aumentaram (39,92 ± 6,1 mg/dL vs 48,00 ± 7,85 mg/dL p = 0,02) e IL6 diminuíram (4,56 ± 1,2 pg / mL vs 2,14 ± 1,0 pg / mL p = 0,02). Houve aumento da distância percorrida no teste de caminhada no grupo exercício (473,80 ± 98,6 metros vs 573,50 ± 74,22 metros p = 0,01). Na avaliação ecocardiográfica, verificou-se que no GE houve diminuição da pressão da artéria pulmonar estimada (31,38 ± 2,9 mmhg vs 24,2 ± 1,7 mmhg p = 0,001). Houve melhora na modulação autonômica no GE (RMSSD 11,7 ± 4,2 vs 18,4 ± 5,7 p=0,02), LFnu (52,9 ± 17,2 vs 32,0 ± 18,2 p=0,02) e HFnu (48,1 ± 17,2 vs 68,0 ± 18,2 p=0,01). Não foram evidenciados efeitos adversos e não houve abandono do treinamento. Baseados nestes resultados, é possível concluir que o exercício aeróbio intradialítico por 12 semanas pode melhorar parâmetros cardiorrespiratórios, hemodinâmicos e autonômicos, com boa aderência e sem eventos adversos, podendo ser usado como medida coadjuvante para melhora clínica destes pacientes.

Chronic kidney disease (CKD) is a clinical condition of high cardiovascular risk and patients in the more advanced stages of the disease who depend on renal replacement therapy often experience cardiorespiratory impairment, high blood pressure levels (use of multiple medications for control), modulation impaired autonomy and varying degrees of inflammation. Thus, this study aims to verify whether intradialytic aerobic exercise has an impact on modifying these variables. The patients were selected in two hemodialysis units in São Luís do Maranhão, Brazil, between May 2016 and October 2019, and were allocated according to acceptance in the control group (CG) and exercise group (EG). The group exercise was submitted to aerobic exercise with bicycle for a period of 12 weeks. Anthropometric physical evaluation, 6-minute walk test (6MWT), echocardiogram, electrocardiogram with analysis of heart rate variability (VFC) and laboratory measurements were performed including interleukin 6 (IL6) before and after 12 weeks in both groups. Thirty-one patients were evaluated 15 patients in the control group (CG) and 16 patients in the exercise group (EG). After 12 weeks of training, there was a decrease in systolic blood pressure in the exercise group compared to baseline (129.8 ± 9.41 mmHg vs 112.00 ± 12.0 mmhg p = 0.03). There were no changes in body composition and in most laboratory tests, except for an increase in KTV (dialysis adequacy index) and a decrease in LDL cholesterol in the exercise group compared to the control group. However, HDL cholesterol levels increased (39.92 ± 6.1 mg / dL vs 48.00 ± 7.85 mg / dL p = 0.02) and IL6 decreased (4.56 ± 1.2 pg / mL vs 2.14 ± 1.0 pg / mL p = 0.02). There was an increase in the distance covered in the walking test in the exercise group (473.80 ± 98.6 m vs 573.50 ± 74.22 m p = 0,01). In the echocardiographic evaluation, it was found that in the EG there was a decrease in the estimated pulmonary artery pressure (31.38 ± 2.9 mmhg vs 24.2 ± 1.7 mmhg p = 0.001). There was an improvement in autonomic modulation in the EG (RMSSD 11.7 ± 4.2 vs 18.4 ± 5.7 p = 0.02), LFnu (52.9 ± 17.2 vs 32.0 ± 18.2 p = 0.02) and HFnu (48.1 ± 17.2 vs 68.0 ± 18.2 p = 0.01). There were no adverse effects and training was not abandoned. Based on these results, it is possible to conclude that intradialytic aerobic exercise for 12 weeks can improve cardiorespiratory, hemodynamic, and autonomic parameters, with good adherence and without adverse events, and can be used as a supporting measure for the clinical improvement of these patients.

RESUMO Introdução: O método mais recomendado para a esterilização dos alicates ortodônticos é a autoclave; porém, o ácido peracético mostrou-se eficaz no processo de esterilização química. Objetivo: O objetivo do presente estudo foi avaliar o efeito corrosivo do ácido peracético e da autoclave no processo de esterilização de alicates ortodônticos. Métodos: Foram selecionados quatro alicates de corte de amarrilho de aço inoxidável, com ponta ativa de carboneto de tungstênio (WC), das marcas Quinelato (Rio Claro/SP, Brasil) e ICE (Cajamar/SP, Brasil), que foram distribuídos em três grupos: 1) Controle (C), o qual não foi submetido à esterilização; 2) Grupo AC, constituído por duas pontas ativas de alicates submetidas a 100 ciclos de esterilização em autoclave; e 3) Grupo AP, formado por duas pontas ativas de alicates submetidas a 100 ciclos de esterilização por imersão em solução de ácido peracético a 2% durante 30 minutos. Resultados: Por meio da análise química (EDS, energia dispersiva de raios X), constatou-se que, após esterilização em autoclave, somente o alicate ICE apresentou corrosão por oxidação (Δ[O] = +24,5%; Δ[Fe] = +5,8% e Δ[WC] = -1,9%), enquanto na esterilização em ácido peracético, ambas as marcas, ICE (Δ[O] = +1,8%; Δ[Fe] = +18,0% e Δ[WC] = -1,1%) e Quinelato (Δ[O] = +5,3%; Δ[Fe] = -10,4% e Δ[WC] = -15,2%), apresentaram corrosão. A análise morfológica demonstrou que o ácido peracético causou uma corrosão localizada em pite em ambas as marcas, enquanto a autoclave ocasionou uma corrosão superficial uniforme no alicate ICE. Conclusão: A autoclave foi o método de esterilização que gerou menor dano corrosivo aos alicates ortodônticos, em comparação à imersão em ácido peracético a 2%.

Correlation Between Parathyroid Hormone Levels with Urinary Magnesium Excretion in Patients with Non-Dialysis Dependent Chronic Kidney Disease.

BACKGROUND: Disorders of mineral metabolism occur in most patients with chronic kidney disease (CKD). The aim of this work was to correlate parathyroid hormone (PTH) levels with urinary magnesium excretion in patients with non-dialysis dependent CKD. METHODS: Cross-sectional study. Concentrations of creatinine, magnesium, calcium, phosphate, parathyroid hormone (PTH), 25-hydroxyvitamin D [25(OH)D] and alkaline phosphatase (ALP) were determined in blood samples. The assessment of urinary magnesium levels was performed by means of total daily excretion and by the excretion fraction (FEMg). RESULTS: The study evaluated 163 patients with a mean age of 60.7 ± 11.7 years and 51.0% were male. In the highest quartile of PTH (>89.5pg/mL), the mean levels of FEMg and ALP were higher (p<0.05). In the unadjusted regression analysis, the following variables were related to serum PTH levels: FEMg (odds ratio (OR) = 1.12; 95% confidence intervals (CI): 1.02-1.23), calcium (OR = 0.45; 95% CI: 0.22-0.90), ALP (OR = 1.02; 95% CI: 1.00-1.03) and eGFR (OR = 0.92; 95% CI: 1.00-1.03). After an adjusted analysis, only one FEMg and ALP will remain correlated with PTH. CONCLUSION: In patients with non-dialysis dependent CKD, FEMg and ALP were some variables that remained associated with PTH.

Development of a Computational Model to Predict Excess Body Fat in Adolescents through Low Cost Variables.

BACKGROUND: Excess body fat has been growing alarmingly among adolescents, especially in low income and middle income countries where access to health services is scarce. Currently, the main method for assessing overweight in adolescents is the body mass index, but its use is criticized for its low sensitivity and high specificity, which may lead to a late diagnosis of comorbidities associated with excess body fat, such as cardiovascular diseases. Thus, the aim of this study was to develop a computational model using linear regression to predict obesity in adolescents and compare it with commonly used anthropometric methods. To improve the performance of our model, we estimated the percentage of fat and then classified the nutritional status of these adolescents. METHODS: The model was developed using easily measurable socio-demographic and clinical variables from a database of 772 adolescents of both genders, aged 10-19 years. The predictive performance was evaluated by the following metrics: accuracy, sensitivity, specificity, and area under ROC curve. The performance of the method was compared to the anthropometric parameters: body mass index and waist-to-height ratio. RESULTS: Our model showed a high correlation (R = 0.80) with the body fat percentage value obtained through bioimpedance. In addition, regarding discrimination, our model obtained better results compared to BMI and WHtR: AUROC = 0.80, 0.64, and 0.55, respectively. It also presented a high sensitivity of 92% and low false negative rate (6%), while BMI and WHtR showed low sensitivity (27% and 9.9%) and a high false negative rate (65% and 53%), respectively. CONCLUSIONS: The computational model of this study obtained a better performance in the evaluation of excess body fat in adolescents, compared to the usual anthropometric indicators presenting itself as a low cost alternative for screening obesity in adolescents living in Brazilian regions where financial resources are scarce.

A Case-control Study of Exercise and Kidney Disease: Hemodialysis and Transplantation.

We aimed to analyze the effect of an exercise training program in autonomic modulation, and exercise tolerance of hemodialysis and kidney-transplanted patients. 4 groups of exercised and non-exercised patients undergoing hemodialysis and kidney-transplanted subjects had their biochemical tests, and heart rate variability evaluations analyzed. Also, sleep quality, anxiety and depression questionnaires were evaluated. Both exercised groups showed improvements in cardiovascular autonomic modulation, biochemical markers, and exercise tolerance after the exercise training program. The exercised kidney-transplanted patients group showed better improvements in cardiovascular autonomic modulation, biochemical markers, and exercise tolerance when compared to the exercised hemodialysis patients group. Both groups showed improvements in sleep quality, anxiety, and depression. The group of kidney-transplanted patients show better results in the cardiovascular autonomic modulation than subjects undergoing hemodialysis. However, the patients undergoing hemodialysis showed improvements in blood pressure, HDL, hemoglobin and phosphorus, changes not observed in the kidney-transplanted group. Exercise is beneficial for both hemodialysis and kidney-transplanted patients groups. However, exercise programs should be focused mainly in improving cardiovascular risk factors in the HD patients.
