Does routine ultrasound change management in the follow-up of patients with vesicoureteral reflux?

Introduction: Children with vesicoureteral reflux (VUR) usually need a renal ultrasound (RUS). There is little data on the role of follow-up RUS in VUR. We evaluated the impact of follow-up RUS on the change in clinical management in patients with VUR.Methods: We prospectively analyzed children with a previous diagnosis of VUR seen in the outpatient clinic with a routine follow-up RUS within 4 months. Variables collected included: demographic data, VUR history, dysfunctional voiding symptoms and concurrent ultrasound findings. Change in management was defined as addition of new medication, nurse counselling, surgery or further investigations.Results: The study included 114 consecutive patients. The mean patient age was 4.5 years old, mean age of VUR diagnosis was 1.7 years, with average follow-up of 2.8 years. A change in management with stable RUS occurred in 14 patients, in which the change included ordering a DMSA in 9, nurse counselling for dysfunctional voiding in 3, and booking surgery in 2 patients. Change on RUS was seen in 4 patients. Multivariable analysis showed that history of urinary tract infection (UTI) since the last follow-up visit was more significant than RUS findings.Conclusions: The RUS findings in most patients followed for VUR remain stable or with minimal changes. The variable showing a significant effect on change in management in our study was history of UTI since the last follow-up visit rather than RUS findings. The value of follow-up RUS for children with VUR may need to be revisited.

Abstract Patients undergoing transcatheter aortic valve replacement (TAVR) may have concomitant mitral regurgitation (MR). The impact of MR at baseline or after TAVR on subsequent prognosis remains to be more precisely determined. We analysed the impact of MR before or after TAVR on prognosis in the systematic analysis of patients treated with TAVR at a nationwide level. Methods Based on the French administrative hospital-discharge database, the study collected information for all consecutive patients with aortic stenosis treated with transfemoral TAVR in France between 2008 and 2018. Cox regression was used for the analysis of predictors of events during follow-up. Results A total of 47,872 patients with transfemoral TAVR were included in the analysis (mean age 83±7 years). Moderate/severe MR was present at baseline (MRb) in 9.5% of the patients. Few patients (1.6%) revealed moderate/severe MR post-TAVR (MRpt). Mean follow-up was 1.31±1.61 years. MRb was associated with an increased cardiovascular mortality (Hazard ratio 1.29, 95% CI 1.20–1.39) and total mortality (Hazard ratio 1.15, 95% CI 1.10–1.21). However, MRb was not an independent predictor in multivariable analysis, neither for cardiovascular mortality (adjusted HR 1.06, 95% CI 0.98–1.14) nor for total mortality (adjusted HR 1.01, 95% CI 0.96–1.07). MRpt was not a predictor of cardiovascular or total mortality. Older age, male sex, history of pulmonary edema/cardiogenic shock, atrial fibrillation, myocardial infarction, diabetes, renal failure, liver disease, pulmonary disease, previous cancer and anemia at baseline independently predicted mortality during follow-up. All of them (but history of cancer) were also independent predictor of cardiovascular death. Conclusion Baseline MR was associated with increased cardiovascular and totality mortality following TAVR but was not an independent predictor of any of them. By contrast, several other predictors of cardiovascular and total mortality were identified. This suggests that MR should not be directly considered to establish the strategy for TAVR decision or for avoiding TAVR-related futility.

The Impact

Chewing betel nut is common in Taiwan. Although previous studies have shown that chewing betel nuts is associated with adverse health effects, findings about the impact on bone density have been inconsistent. Therefore, the aim of this study was to investigate the correlation between betel nut chewing and calcaneus ultrasound T-score in a longitudinal study of 118,856 participants from the Taiwan Biobank. Of these participants, 27,002 were followed up with for a median of 4 years. The T-score of the calcaneus was measured in the non-dominant foot using ultrasound. Multivariable analysis showed that a history of chewing betel nut (coefficient β = −0.232; p < 0.001) was significantly associated with low baseline T-score in all participants (n = 118,856). In addition, a long duration of betel nut chewing (per 1 year; coefficient β = −0.003; p = 0.022) was significantly associated with a low baseline T-score in the participants with a history of chewing betel nut (n = 7210). Further, a long duration of betel nut chewing (per 1 year; coefficient β = −0.004; p = 0.039) was significantly associated with a low ΔT-score in the participants with a history of chewing betel nut (n = 1778) after 4 years of follow-up. In conclusion, our results showed that betel nut chewing was associated with a decrease in calcaneus ultrasound T-score, and thus, it is important to stop chewing betel nut to help prevent an increased risk of osteoporosis in the Taiwanese population.

BackgroundWe assessed the impact of anorectal malformation (ARM) on the kidneys of children with dilating vesicoureteral reflux (D-VUR) ≥grade III using a simple dimercaptosuccinic acid (DMSA) scintigraphy scan based renal dysfunction score (RDS).MethodsThe medical records of 121 patients with D-VUR treated between 2000 and 2014 were reviewed retrospectively. After excluding patients with secondary D-VUR (n=18), presence of ARM was used to create two groups: ARM+ (n=12 cases; 15 ureters) and ARM– (n=91 cases; 131 ureters). Types of ARM, grades of D-VUR, bladder and bowel dysfunction (BBD) and RDS were compared.ResultsPatient demographics, mean follow-up, grades of D-VUR and history of urinary tract infections were not significantly different. BBD was significantly higher in ARM+ (41.7% versus 7.7%, p=0.0006). RDS was significantly higher in ARM+ (p=0.036). Grades of D-VUR were significantly lower in ARM– with low RDS (p=0.008). During follow-up, changes in DMSA uptake over time were not observed in ARM+.ConclusionsWhile renal cortical lesions were correlated with grade of D-VUR in ARM– and RDS was significantly higher in ARM+, BBD did not appear to contribute to progressive renal dysfunction as is commonly believed. In fact, no progression in renal cortical lesions was observed in ARM+ based on RDS data. Renal cortical lesions may possibly be a feature of ARM, a topic that warrants further study.

The Impact

Data supporting the use of etoposide-based therapy in hemophagocytic lymphohistiocytosis (HLH) arise largely from pediatric studies. There is a lack of comparable data among adult patients with secondary HLH. We conducted a retrospective study to assess the impact of etoposide-based therapy on outcomes in adult secondary HLH. The primary outcome was overall survival. The log-rank test was used to compare Kaplan-Meier distributions of time-to-event outcomes. Multivariable Cox proportional hazards modeling was used to estimate adjusted hazard ratios (HRs) with 95% confidence intervals (CIs). Ninety adults with secondary HLH seen between January 1, 2009, and January 6, 2020, were included. Forty-two patients (47%) received etoposide-based therapy, while 48 (53%) received treatment only for their inciting proinflammatory condition. Thirty-three patients in the etoposide group (72%) and 32 in the no-etoposide group (67%) died during follow-up. Median survival in the etoposide and no-etoposide groups was 1.04 and 1.39 months, respectively. There was no significant difference in survival between the etoposide and no-etoposide groups (log-rank <i>p</i> = 0.4146). On multivariable analysis, there was no association between treatment with etoposide and survival (HR for death with etoposide = 1.067, 95% CI: 0.633–1.799, <i>p</i> = 0.8084). Use of etoposide-based therapy was not associated with improvement in outcomes in this large cohort of adult secondary HLH patients.

The Impact

Cardiovascular magnetic resonance (CMR) is used to investigate suspected acute myocarditis, however most supporting data is retrospective and few studies have included parametric mapping. We aimed to investigate the utility of contemporary multiparametric CMR in a large prospective cohort of patients with suspected acute myocarditis, the impact of real-world variations in practice, the relationship between clinical characteristics and CMR findings and factors predicting outcome. 540 consecutive patients we recruited. The 113 patients diagnosed with myocarditis on CMR performed within 40 days of presentation were followed-up for 674 (504–915) days. 39 patients underwent follow-up CMR at 189 (166–209) days. CMR provided a positive diagnosis in 72% of patients, including myocarditis (40%) and myocardial infarction (11%). In multivariable analysis, male sex and shorter presentation-to-scan interval were associated with a diagnosis of myocarditis. Presentation with heart failure (HF) was associated with lower left ventricular ejection fraction (LVEF), higher LGE burden and higher extracellular volume fraction. Lower baseline LVEF predicted follow-up LV dysfunction. Multiparametric CMR has a high diagnostic yield in suspected acute myocarditis. CMR should be performed early and include parametric mapping. Patients presenting with HF and reduced LVEF require closer follow-up while those with normal CMR may not require it.

Background: In the ISCHEMIA (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) trial, all-cause mortality was similar in patients with stable ischemic heart disease (SIHD) randomized to invasive (INV) and conservative (CON) management strategies. This analysis details specific causes of cardiovascular (CV) and non-CV mortality by treatment group. Methods: In ISCHEMIA, 289 deaths occurred after a median follow-up of 3.2 years; 145 (5.6%) in INV and 144 (5.6%) in CON (HR 1.05, CI 0.83-1.32). Deaths were adjudicated by an independent Clinical Events Committee as CV, non-CV with or without a CV contributor or undetermined. The protocol defined CV death as deaths from CV causes, non-CV causes with CV contributor, and cause undetermined; non-CV death was defined as death from non-CV causes without a CV contributor. Multivariable analyses were used to identify factors associated with cause-specific death. Results: CV death was similar between groups [INV 92 (3.6%), CON 111 (4.3%); HR 0.87 (CI 0.66, 1.15)], but INV had more non-CV death [INV 53 (2.0%), CON 33 (1.3%); HR 1.63 (CI 1.06, 2.52)]; fewer undetermined deaths [INV 12 (0.5%) and CON 26 (1.0%); HR 0.48 (0.24, 0.95)] and more malignancy deaths [INV 41 (1.6%), CON 20 (0.8%); HR 2.11 (1.24, 3.61)]. In multivariable analysis, risk factors associated with CV death were age [HR 1.42 (CI 1.19-1.70) per 10-year increase], diabetes [HR 1.39 (CI 1.03-1.87)], history of heart failure [HR 1.96 (CI 1.33-2.91)], and eGFR [HR 1.18 (CI 1.11-1.26) per 5-ml/min decrease below 80ml/min]. Factors associated with non-CV death were age [HR 2.31 (CI 1.75-3.03) per 10-year increase] and randomization to INV [HR 1.76 (CI 1.13-2.75)]. Conclusions: In ISCHEMIA, all-cause mortality was similar for the INV and CON strategies. Excess non-CV deaths in INV with a higher number of deaths from malignancy but a higher number of undetermined deaths in CON requires further evaluation.

The Impact

Background: Late gadolinium enhancement (LGE) by cardiac MR (CMR) has been related to adverse clinical outcomes in patients with nonischemic dilated cardiomyopathy (NIDC). But, a statistically significant association between LGE and arrhythmic risk in NIDC has not been demonstrated consistently. This study evaluated the impact of the presence, location and pattern of LGE on arrhythmic risk prediction in NICM. Methods: This study included 365 patients (54±15years) with NICM who underwent CMR. The extent, location and pattern of LGE were categorized. We analyzed for the primary outcome of ventricular arrhythmia (VA) including sustained or nonsustained ventricular tachycardia (VT), appropriate implantable cardioverter-defibrillator (ICD) intervention and ventricular fibrillation (VF). Cardiac death and hospitalization for heart failure (HF) were evaluated as secondary outcomes. Results: LGE was seen in 267 (73 %) patients. During median follow-up of 44±36 months, patients with LGE had higher incidence of cardiac death (15 % vs. 2 %, p<0.001), hospitalization for HF (40 % vs. 15 %, p<0.001) and VA (14% vs. 6%, p=0.03). In multivariable analysis, the presence of LGE (HR 2.78; 95% CI 1.10-7.02; p=0.03) was the independent predictor of arrhythmias. Patients with extensive LGE had higher VA (32% vs. 10%, p<0.001) with lower cumulative survival free of VA than those without extensive LGE (p=0.001). The frequent LGE location was as follows: LV septum 64%, LV-RV junction 42% and inferior 10%. VA was lower in patients with than without localized LGE limited to LV-RV junction (21% vs. 46%, p=0.005). Interestingly, while the incidence of ventricular arrhythmia was higher in patients with transmural LGE (29% vs. 10%, p=0.003), it was lower in those with patch LGE (2% vs. 16%, p=0.02) than the other patients. Conclusions: In patients with NICM, the LGE was an independent prognostic predictor of VA. Extensive LGE and specific location of LGE was related with the arrhythmic events.

Introduction: Studies have previously shown that atrial fibrillation (AF) is associated with dementia. The mechanisms are likely multifactorial, but may involve treatment strategies that include anticoagulation use and rhythm management, particularly when used early. Patients that have earlier-life depression are at risk of dementia. However, depression diagnosis in AF patients may indicate a patient at higher risk of developing dementia and whether treatments ameliorate that risk is unknown. Methods: A total of 132,703 AF patients without a history of dementia were studied. History of depression was determined at the time of AF diagnosis. Patients were deemed as having a follow-up ablation if it occurred prior to a dementia diagnosis. Patients were stratified into 4 groups based on depression history and follow-up ablation status: no depression, ablation (n=5,960); no depression, no ablation (n=106,986); depression, ablation (n=923); and depression, no ablation (n=18,834). Patients were followed for 5-year incidence of dementia. Results: A total of 14.9% (n=19,757) pts had a history of depression at the time of AF diagnosis. The mean time between depression and AF diagnoses was 4.9±4.8 years. Patients with depression were younger (68±15 vs. 71±14 years), more likely to be female (62% vs. 44%), and had more cardiovascular comorbidities. Mean time to ablation was 1.3±1.4 days (median: 7.7 months) from AF diagnosis. Frequencies of 5-year dementia were: no depression, ablation=1.6%; no depression, no ablation=5.2%; depression, ablation=4.7%; and depression, no ablation=9.7%, p<0.0001. Multivariable comparisons between the groups are shown in the Figure. Conclusion: In AF patients with and without depression, ablation was associated with a lower risk of incident dementia. Rhythm control approaches that improve long-term brain perfusion may represent a means to impact cognitive declines in patients at higher risk because of earlier-life depression.

Introduction: Certain patient demographics and biomarkers have been shown to predict survival in patients infected with COVID-19. However, predictors of outcome in patients who are critically ill and require advanced respiratory support are unclear. Methods: We performed a multicenter analysis of 159 consecutive patients with confirmed COVID-19 who were admitted to Intensive Care Unit (ICU) between March 01, 2020 and April 30, 2020. Patients were then followed until May 23, 2020. Demographic data (age, sex, race, BMI) and past medical history (hypertension, diabetes, COPD, CKD, history of cardiac ischemic disease, atrial fibrillation and heart failure) were recorded. Laboratory values (troponin, CPK, pro-BNP, ferritin, LDH and d-dimer) were analyzed. Patient status was classified as either alive or deceased at hospital discharge or the end of follow up period. Results: Mean patient age was 66+/-15 and 53% were male. Mean BMI was 31+/- 9. Mean hospital ICU stay was 11+/-8 days. Mortality rate of this ICU cohort at the end of follow-up was 63%. Fifty-five (34%) patients were discharged from the hospital. A multivariable logistic regression analysis identified four factors (age, prior history of diabetes, prior history of atrial fibrillation and elevated troponin) that had significant and independent contributions to the likelihood of survival. Each increase in decade of age above 40 (p = 0.010) was predicted to reduce survival by 30%, the presence of diabetes (p = 0.041) by 57%, a prior history of atrial fibrillation (p= 0.011) by 75%, and each increase of 0.1 ng/mL of troponin above 0.05 ng/ml (p = 0.001) by 55%. Conclusion: Mortality of critically ill COVID-19 patients is high. Early aggressive treatment of high-risk patients identified in this study (advanced age, history of diabetes and atrial fibrillation and elevated troponin) could improve clinical outcome. The highly predictive value of elevated troponin levels on survival may indicate cardiac involvement of COVID-19 infection as a determinant of mortality. Additionally, of available published literature at this time, this is the first study that suggests a relationship between atrial fibrillation and increased mortality from COVID-19. Larger studies are needed to confirm these findings.
