RESUMO

Resumo Objetivo Avaliar e comparar as fórmulas CKD-EPI, BIS1 e MDRD e o limiar diagnóstico de 45 e 60 ml/min/1,73m2 em pacientes idosos. Método Estudo observacional do tipo transversal, de caráter descritivo e analítico. Foram incluídos pacientes atendidos em ambulatório de referência entre janeiro/2020 e junho/2022, com idade ≥65 anos. Foram excluídos pacientes com apenas uma dosagem de creatinina ou com alterações transitórias da TFG. Resultados Observou-se que entre o grupo de pacientes com idade entre 65-74 anos e 75-84 anos as estimativas da TFG feitas pela fórmula CKD-EPI foram superiores às fórmulas BIS1 e MDRD. Enquanto, no grupo de pacientes com 85-94 anos a CKD-EPI não apresentou diferença quando comparada com MDRD, permaneceu com estimativas maiores apenas quando comparada com a BIS1. Observamos maior dispersão entre CKD-EPI e BIS1, mostrando menor concordância entre essas fórmulas, confirmada pelo teste Kappa (76,7%) e a concordância quase perfeita entre CKD-EPI e MDRD. Conclusão A fórmula BIS1 apresentou melhor correlação da diminuição da TFGe conforme o avanço das faixas etárias, podendo-se relacionar com o processo de envelhecimento renal fisiológico, podendo ser uma ferramenta auxiliar na estimativa da TFG em idosos, auxiliando no diagnóstico mais preciso da DRC, assim como, no planejamento de intervenções que possam retardar a progressão da DRC e prever risco de mortalidade por doenças cardiovasculares.


Abstract Objective To evaluate and compare the CKD-EPI, BIS1 and MDRD formulas and diagnostic thresholds of 45 and 60 ml/min/1.73m2 in older patients. Method A cross-sectional, descriptive, analytical observational study was conducted. Patients aged ≥65 years treated at a referral outpatient clinic between January 2020 and June 2022, were assessed. Patients with only one creatinine level or with transient GFR abnormalities were excluded. Results The GFR estimates using the CKD-EPI formula were higher than both the BIS1 and MDRD formulas in patient groups aged 65-74 years and 75-84 years. In the group of patients aged 85-94 years, the CKD-EPI showed no difference when compared with the MDRD, yielding higher estimates only compared with the BIS1. Greater dispersion was found between the CKD-EPI and BIS1, showing less agreement between these formulas, as confirmed by the Kappa test (76.7%), while there was almost perfect agreement between the CKD-EPI and MDRD. Conclusion The BIS1 formula showed stronger correlation of the decrease in eGFR with advancing age, reflecting the physiological renal aging process and serving as a potentially useful tool for estimating GFR in older adults. The formula can help provide a more accurate diagnosis of CKD and aid planning of interventions to slow the progression of CKD and predict the risk of mortality from cardiovascular diseases.

RESUMO

PURPOSE: The purpose of this study was to determine factors significantly associated with mortality and length of stay (LOS) in admissions to the pediatric intensive care unit (PICU) for traumatic brain injury (TBI). METHODS: A cross-sectional, retrospective cohort study that identified PICU admissions with TBI from forty-nine hospitals in the USA using the Pediatric Health Information System database from 2016 to 2021. Univariable analyses comparing those who did and did not experience mortality were performed. The following regression analyses were conducted: logistic regression with mortality as dependent variable; linear regression with LOS as the dependent variable; logistic regression with mortality as the dependent variable but only included patients with cerebral edema; and linear regression with LOS as the dependent variable but only included patients who survived. From the regression analysis for mortality in all TBI patients was utilized to develop a mortality risk score. RESULTS: A total of 3041 admissions were included. Those with inpatient mortality (18.5%) tended to be significantly younger (54 vs. 92 months, p < 0.01), have < 9 pediatric Glasgow Coma Scale on admission (100% vs. 52.9%, p < 0.01) and more likely to experience acute renal, hepatic and respiratory failure, acidosis, central diabetes insipidus, hyperkalemia, and hypocalcemia. Regression analysis identified that pediatric Glasgow Coma Scale, alkalosis and cardiac arrest significantly increased risks of mortality. The TBI mortality risk score had an area under the curve of 0.89 to identify those with mortality; a score of 6 ≤ was associated with 88% mortality. CONCLUSION: Patients admitted to the PICU with TBI have 18.5% risk of inpatient mortality with most occurring the first 48 h and these are characterized with greater multisystem organ dysfunction, received medical and mechanical support. TBI mortality risk score suggested is a practical tool to identify patients with an increase likelihood to die.

RESUMO

BACKGROUND: Kawasaki disease is a vasculitis that can lead to cardiac complications, including coronary artery disease and cardiogenic shock. Various scoring systems have been developed to determine those that will be refractory to routine intravenous immunoglobulin therapy or develop coronary artery disease. The objective of this study was to determine if the neutrophil-lymphocyte ratio could predict refractory disease and coronary artery lesions in patients with Kawasaki disease. METHODS: A systematic review of the literature was performed to identify manuscripts describing comparisons of neutrophil-lymphocyte ratio between those who had refractory disease and those who did not, and between those who developed coronary artery lesions and those who did not. Mean difference was compared between groups. Areas under the curve were utilised to determine the pooled area under the curve. RESULTS: 12 studies with 5593 patients were included in the final analyses of neutrophil-lymphocyte ratio for the prediction of refractory disease. Neutrophil-lymphocyte ratio before therapy was higher in refractory disease with a mean difference of 2.55 (p < 0.01) and pooled area under the curve of 0.724. Neutrophil-lymphocyte ratio after therapy was higher in refractory disease with a mean difference of 1.42 (p < 0.01) and pooled area under the curve for of 0.803. Five studies with 1690 patients were included in the final analyses of neutrophil-lymphocyte ratio for the prediction of coronary artery lesions. Neutrophil-lymphocyte ratio before therapy was higher in coronary artery lesions with a mean difference of 0.65 (p < 0.01). CONCLUSION: The use of neutrophil-lymphocyte ratio may help physicians in the identification of patients at risk of refractory disease and coronary artery lesions in patients with Kawasaki disease.

RESUMO

Sample size and statistical power are often limited in pediatric cardiology studies due to the relative infrequency of specific congenital malformations of the heart and specific circulatory physiologies. The primary aim of this study was to determine what proportion of pediatric cardiology randomized controlled trials achieve an 80% statistical power. Secondary aims included characterizing reporting habits in these studies. A systematic review was performed to identify pertinent pediatric cardiology randomized controlled trials. The following data were collected: publication year, journal, if "power" or "sample size" were mentioned if a discrete, primary endpoint was identified. Power analyses were conducted to assess if the sample size was adequate to demonstrate results at 80% power with a p-value of less than 0.05. A total of 83 pediatric cardiology randomized controlled trials were included. Of these studies, 48% mentioned "power" or "sample size" in the methods, 49% mentioned either in the results, 12% mentioned either in the discussion, and 66% mentioned either at any point in the manuscript. 63% defined a discrete, primary endpoint. 38 studies (45%) had an adequate sample size to demonstrate differences with 80% power at a p-value of less than 0.05. A majority of these are not powered to reach the conventionally accepted 80% power target. Adequately powered studies were found to be more likely to report "power" or "sample size" and have a discrete, primary endpoint.

RESUMO

INTRODUCTION: In patients with right ventricular diastolic dysfunction after complete repair of tetralogy of Fallot, some employ the use of beta-blockade. The theoretical benefit of this therapy is felt to be one of the two: 1) reduction in heart rate with subsequent increase in diastolic filling time and stroke volume; 2) halting or reversal of right ventricular remodelling. This study aimed to characterise the use of beta-blockade in paediatric admissions with complete repair of tetralogy of Fallot and characterise the effects of beta-blockade on admission characteristics. METHODS: Admissions from 2004 to 2015 in the Pediatric Health Information System database with complete repair of tetralogy of Fallot were identified. Characteristics between admissions with and without beta-blockade were compared by univariate analysis. Next, regression analyses were conducted to determine the independent association of beta-blockade on length of admission, billed charges, cardiac arrest, and inpatient mortality while controlling for demographic variables and comorbidities. RESULTS: A total of 3594 admissions were included in the final analyses. Of these, 371 employed beta-blockade. Admissions with beta-blockade were more likely to have heart failure and tachyarrhythmias. These admissions also tended to be longer by univariate analysis. Regression analyses demonstrated that beta-blockade was independently associated with a 2.8-day increase in length of stay and no statistically significant change in billed charges, cardiac arrest, or inpatient mortality. CONCLUSIONS: Beta-blockade after complete repair of tetralogy of Fallot is associated with a longer length of stay but did not statistically significantly impact billed charges, cardiac arrest, or inpatient mortality.

RESUMO

INTRODUCTION: To assess the efficacy of C-reactive protein (CRP) and procalcitonin (PCT) at identifying infection in children after congenital heart surgery (CHS) with cardiopulmonary bypass (CPB). MATERIALS AND METHODS: Systematic review of the literature was conducted to identify studies with data regarding CRP and/or PCT after CHS with CPB. The primary variables identified to be characterized were CRP and PCT at different timepoints. The main inclusion criteria were children who underwent CHS with CPB. Subset analyses for those with and without documented infection were conducted in similar fashion. A p value of less than .05 was considered statistically significant. RESULTS: A total of 21 studies were included for CRP with 1655 patients and a total of 9 studies were included for PCT with 882 patients. CRP peaked on postoperative Day 2. A significant difference was noted in those with infection only on postoperative Day 4 with a level of 53.60 mg/L in those with documented infection versus 29.68 mg/L in those without. PCT peaked on postoperative Day 2. A significant difference was noted in those with infection on postoperative Days 1, 2, and 3 with a level of 12.9 ng/ml in those with documented infection versus 5.6 ng/ml in those without. CONCLUSIONS: Both CRP and PCT increase after CHS with CPB and peak on postoperative day 2. PCT has a greater statistically significant difference in those with documented infection when compared to CRP and a PCT of greater than 5.6 ng/ml should raise suspicion for infection.

RESUMO

Hepatoportoenterostomy remains the cornerstone of treatment for biliary atresia. Current employed techniques include laparoscopy and open surgery. This study aims to determine if either method provides an advantage. Following PRISMA guidelines, a systematic review was conducted. Nineteen studies were included. Mean operative time 34.98 (95% CI 20.10, 49.85; p ≤ 0.00001) was longer in laparoscopic while bleeding volumes - 16.63 (95% CI - 23.39, - 9.86; p ≤ 0.00001) as well as the time to normal diet - 2.42 (95% CI - 4.51, - 0.32; p = 0.02) were lower in the laparoscopic group. No differences were observed in mean length of stay - 0.83. Similar complication, transfusions, postoperative cholangitis 0.97, and transplant free survival rates 1.00 (0.63, 1.60; p = 0.99) were seen between groups. Laparoscopic portoenterostomy provides advantages on operative time and bleeding as well as to normal diet when compared to open procedures. Both procedures showed no differences in length of stay, complications, cholangitis, and importantly, native liver survival. Level of evidence: III.

RESUMO

OBJECTIVE: Clinical clerkships are a fundamental component of medical education where students' learning is aided by exposure to real patients in diverse practical settings. Countless programs use overnight call shifts as an essential part of their clerkships. There has been concerns about the negative effects these shifts have on students. The study aims to determine relations between call schedule, lecture attendance, and academic and clinical performance. METHODS: One hundred and eight medical students were followed during their surgery clerkship. Students on a Q3 schedule had an on-call shift once every 3 nights, while students on a Q4 schedule once every 4 nights. Their academic performance was evaluated using their exams grades, while their clinical performance was evaluated by their attending physicians. Burnout syndrome was measured using Maslach Inventory. RESULTS: A total of 108 medical students attended their surgical clerkship. Sixty-nine students were under the Q3 call schedule while 39 students in the Q4 call schedule. Mean lecture attendance for students in Q3 was 82.7% (17.3%) compared to 90% (11.2%) (p = 0.020). Final exam grades were different between groups, with Q3 scoring a mean 71.55 (9.3) compared to Q4 85.07 (9.8) (p = 0.001). Clinical performance score means were similar between groups (p = 0.777). Q4 had 74% and Q3 had 49.3% of the students with >90% of attendance (p = 0.008). Q4 had 2.6% students with <70% attendance compared to Q3 with 23.2% (p = 0.008). Students with >90% attendance regardless of call schedule, scored higher in both midterms and final exams (p = 0.002; p = 0.001). Burnout prevalence was higher in students on the Q3 schedule with 28.6% compared to 4.7% of those on the Q4 schedule (p = 0.003). CONCLUSIONS: Students with less call frequency were associated with an improvement in lecture attendance and academic performance, and a lower burnout syndrome rate, without impacting clinical performance. Students with higher attendance regardless of call schedules performed higher academically. Further studies should evaluate the impact on clinical performance and exposure more thoroughly.

RESUMO

BACKGROUND: Lenticulostriate artery aneurysms (LSAs) are rare vascular aberrations. Despite the potentially catastrophic sequelae of aneurysmal rupture, the optimal management strategy for LSA aneurysms has not been determined. The aim of the present review is to provide an overview of the clinical presentation and treatment strategies for LSA aneurysms. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a literature search was conducted in the PubMed, Cochrane, EBSCOhost, Scopus, Web of Science, and ProQuest search engines to identify reported studies of LSA aneurysms until July 1, 2020. A descriptive analysis was performed. RESULTS: A total of 71 studies with 112 cases of LSA aneurysms were included. Patient age ranged from 2 months to 83 years (median, 44.5 years). Male and female patients were affected similarly (49% and 51%, respectively). The most common presentation was aneurysmal rupture (78%), and headache was the most frequently reported symptom (36%). Overall, 48% of the patients had undergone underwent surgical treatment, 30% conservative management, 21% endovascular treatment, and 1% radiosurgery. Four patients died, all of whom had presented with aneurysmal rupture. CONCLUSION: We have summarized the reported cases of LSA aneurysms, with their clinical presentation, management, and outcomes, for physicians who may be confronted with this diagnosis. Future studies that use available classification systems and include as much detail as possible should be encouraged to fully elucidate the optimal management strategy for these patients.

RESUMO

Vasopressin has been used to augment blood pressure; however, cardiovascular effects after cardiac surgery have not been well established. The primary objective of this study was to survey the current literature and quantify the pooled effect of vasopressin on hemodynamic parameters in children after pediatric cardiac surgery. A systematic review was conducted to identify studies characterizing the hemodynamic effects of vasopressin after pediatric cardiac surgery. Studies were assessed and those of satisfactory quality with pre- and post-vasopressin hemodynamics for each patient were included in the final analyses. 6 studies with 160 patients were included for endpoints during the first 2 h of infusions. Patients who received vasopressin infusion had greater mean, systolic, and diastolic blood pressures and lower heart rates at 2 h after initiation. 8 studies with 338 patients were included for the effects at 24 h. Patients who received vasopressin infusion had lower central venous pressures and decreased lactate concentrations 24 h after initiation. A subset analysis for children with functionally univentricular hearts found significant decrease in inotrope score and central venous pressure. A subset analysis for neonates found significant decrease in inotrope score and fluid balance. Vasopressin leads to decrease in heart rate and increase in blood pressure in the first 2 h of initiation. Later effects include decrease in inotrope score, central venous pressure, fluid balance, and in lactate within the first 24 h. Findings vary in neonates and in those with functionally univentricular hearts although beneficial effects are noted in both.

RESUMO

Uncomplicated urinary tract infections rank among the most frequent bacterial infections in women in the outpatient setting and represent a major cause of antimicrobial prescription. The aims of this study were to assess frequencies and antimicrobial resistance of current uropathogens causing uncomplicated urinary tract infection. In a prospective multicenter study, patients were recruited in ambulatory settings of four participating hospitals between June 2011 and December 2013. We analyzed 138 patients that met clinical and bacteriological diagnostic criteria. The mean age was 28 years. Cystitis was defined in 70% (n: 97) and pyelonephritis in 30% (n: 41). Frequencies of isolated microorganisms were: Escherichia coli 70% (n: 97), Staphylococcus saprophyticus 17% (n: 24), Proteus spp. 7% (n: 10), Klebsiella spp. 4% (n: 5), Enterococcus spp. and Pseudomonas aeruginosa 1 (0.7%) each. The antimicrobial resistance was: ampicillin-sulbactam 37% (n: 51) cephalexin 28% (n: 39), trimethoprim/sulfamethoxazole 22% (n: 31), nitrofurantoin 12% (n: 17), gentamicin 7% (n: 10) and ciprofloxacin 5% (n: 7). The levels of resistance found for ampicillin-sulbactam, trimethoprim/sulfamethoxazole and cephalexin were higher than those previously reported in Argentina. A better knowledge of the etiology and local antimicrobial susceptibility allows the design of more adequate guidelines for empirical treatment.

RESUMO

La infección urinaria no complicada en mujeres es un motivo frecuente de consulta e indicación de antimicrobianos. El objetivo de este estudio fue definir etiología y resistencia a antimicrobianos en episodios de infección urinaria no complicada. Este estudio prospectivo incluyó mujeres premenopáusicas no embarazadas, con infección urinaria no complicada, que consultaron en un hospital público y tres centros privados de las ciudades de Buenos Aires y La Plata (2011-2013). La edad media de 138 pacientes con infección confirmada por urocultivo fue 28 años. El diagnóstico fue cistitis en 97 (70%) y pielonefritis en 41 (30%). Las frecuencias de los microorganismos aislados fueron: Escherichia coli 97 (70%), Staphylococcus saprophyticus 24 (17%), Proteus spp. 10 (7%), Klebsiella spp. 5 (4%), Enterococcus spp. 1 (0.7%) y Pseudomonas aeruginosa 1 (0.7%). Las frecuencias de resistencia a antimicrobianos fueron: ampicilina-sulbactam 51 (37%), cefalexina 39 (28%), trimetoprima/sulfametoxazol 31 (22%), nitrofurantoína 17 (12%), gentamicina 10 (7%) y ciprofloxacina 7 (5%). La frecuencia de resistencia a ampicilina-sulbactam, trimetoprima/sulfametoxazol y cefalexina es mayor que las previamente publicadas en Argentina, lo que limita su recomendación para el tratamiento empírico. Una mejor comprensión de la etiología y la susceptibilidad antimicrobiana local permite el diseño de pautas más adecuadas para el tratamiento empírico.
