RESUMO
Despite increasing prevalence of hypertension in youth and high adult cardiovascular mortality rates, the long-term consequences of youth-onset hypertension remain unknown. This is due to limitations of prior research such as small sample sizes, reliance on manual record review, and limited analytic methods that did not address major biases. The Study of the Epidemiology of Pediatric Hypertension (SUPERHERO) is a multisite retrospective Registry of youth evaluated by subspecialists for hypertension disorders. Sites obtain harmonized electronic health record data using standardized biomedical informatics scripts validated with randomized manual record review. Inclusion criteria are index visit for International Classification of Diseases Diagnostic Codes, 10th Revision (ICD-10 code)-defined hypertension disorder ≥January 1, 2015 and age <19 years. We exclude patients with ICD-10 code-defined pregnancy, kidney failure on dialysis, or kidney transplantation. Data include demographics, anthropomorphics, U.S. Census Bureau tract, histories, blood pressure, ICD-10 codes, medications, laboratory and imaging results, and ambulatory blood pressure. SUPERHERO leverages expertise in epidemiology, statistics, clinical care, and biomedical informatics to create the largest and most diverse registry of youth with newly diagnosed hypertension disorders. SUPERHERO's goals are to (i) reduce CVD burden across the life course and (ii) establish gold-standard biomedical informatics methods for youth with hypertension disorders.
RESUMO
BACKGROUND: Therapeutic plasma exchange (TPE) is used in kidney diseases as an adjunct treatment. Little has been described as to its effectiveness in kidney disorders in children. This study aimed to assess the safety, efficacy, and outcomes of patients who underwent TPE for kidney indications. METHODS: Retrospective chart review of patients receiving TPE from 2010 to 2018 for kidney indications, such as antibody-mediated rejection, bone marrow transplant-associated thrombotic microangiopathy (TA-TMA), atypical hemolytic uremic syndrome, transplant recurrence of focal segmental glomerulosclerosis, and glomerulonephritis. Outcomes assessed were trends in kidney function, mortality, and progression to stage 5 chronic kidney disease (CKD 5). Significant hypocalcemia was defined as ionized calcium < 1 mmol/L. RESULTS: A total of 641 TPE procedures were performed on 47 patients (25 male). Average age was 12.8 ± 5.9 years. Median glomerular filtration rate (GFR) improved from baseline to end of TPE treatments (pre 44.9 (19.8, 79), end 56.1 (23, 98) [p = 0.02]). Ten out of 47 children developed CKD 5. Seven out of 47 patients died; 5 had TA-TMA. Initial 7 consecutive sessions were reviewed for complications. Among 335 procedures, 41 episodes of significant hypocalcemia were noted (12.2%); only 1 was symptomatic. Of the 26 episodes (7.7%) of allergic reactions, all were associated with the use of FFP; 5 were anaphylactic. No TPE-associated mortality was noted. CONCLUSIONS: TPE is a relatively well-tolerated useful adjunct therapy in children with kidney indications. The benefit of TPE has to be balanced with risks such as hypocalcemia and allergic reactions which can occur more frequently with FFP. Graphical abstract.

BACKGROUND: Children are recognised as at lower risk of severe COVID-19 compared with adults, but the impact of immunosuppression is yet to be determined. This study aims to describe the clinical course of COVID-19 in children with kidney disease taking immunosuppressive medication and to assess disease severity. METHODS: Cross-sectional study hosted by the European Rare Kidney Disease Reference Network and supported by the European, Asian and International paediatric nephrology societies. Anonymised data were submitted online for any child (age <20 years) with COVID-19 taking immunosuppressive medication for a kidney condition. Study recruited for 16 weeks from 15 March 2020 to 05 July 2020. The primary outcome was severity of COVID-19. RESULTS: 113 children were reported in this study from 30 different countries. Median age: 13 years (49% male). Main underlying reasons for immunosuppressive therapy: kidney transplant (47%), nephrotic syndrome (27%), systemic lupus erythematosus (10%). Immunosuppressive medications used include: glucocorticoids (76%), mycophenolate mofetil (MMF) (54%), tacrolimus/ciclosporine A (58%), rituximab/ofatumumab (11%). 78% required no respiratory support during COVID-19 illness, 5% required bi-level positive airway pressure or ventilation. Four children died; all deaths reported were from low-income countries with associated comorbidities. There was no significant difference in severity of COVID-19 based on gender, dialysis status, underlying kidney condition, and type or number of immunosuppressive medications. CONCLUSIONS: This global study shows most children with a kidney disease taking immunosuppressive medication have mild disease with SARS-CoV-2 infection. We therefore suggest that children on immunosuppressive therapy should not be more strictly isolated than children who are not on immunosuppressive therapy.
RESUMO
Pediatric hypertension (HTN) is a growing problem worldwide that can be attributed to various risk factors, including the upward trend in obesity and poor lifestyle choices. Pediatric HTN will eventually lead to adult HTN and cardiovascular disease. There is concern that HTN in children and adolescents is often underdiagnosed. This article highlights important risk factors and chronic conditions associated with HTN along with complications such as end organ damage and cardiovascular disease. This article also outlines cost-effective diagnostic evaluations and step-wise treatment options, including nonpharmacological interventions such as lifestyle modifications as well as medical management based on the most recent American Academy of Pediatrics Clinical Practice Guidelines.

Hypertension is the leading risk factor for cardiovascular disease and leading cause of premature death globally. In 2008, approximately 40% of adults were diagnosed with hypertension, with more than 1.5 billion people estimated to be affected globally by 2025. Hypertension disproportionally affects low- and middle-income countries, where the prevalence is higher and where the health systems are more fragile. This qualitative study explored patients' experiences on the management and control of hypertension in rural Bangladesh, Sri Lanka and Pakistan. We conducted sixty semi-structured interviews, with 20 participants in each country. Hypertensive individuals were recruited based on age, gender and hypertensive status. Overall, patients' reported symptoms across the three countries were quite similar, although perceptions of hypertension were mixed. The majority of patients reported low knowledge on how to prevent or treat hypertension. The main barriers to accessing health services, as reported by participants, were inadequate services and poor quality of existing facilities, shortage of medicine supplies, busyness of doctors due to high patient load, long travel distance to facilities, and long waiting times once facilities were reached. Patients also mentioned that cost was a barrier to accessing services and adhering to medication. Many patients, when asked for areas of improvement, reported on the importance of the provider-patient relationship and mentioned valuing doctors who spent time with them, provided advice, and could be trusted. However, most patients reported that, especially at primary health care level and in government hospitals, the experience with their doctor did not meet their expectations. Patients in the three countries reported desire for good quality local medical services, the need for access to doctors, medicine and diagnostics and decreased cost for medication and medical services. Patients also described welcoming health care outreach activities near their homes. Areas of improvement could focus on reorienting community health workers' activities; involving family members in comprehensive counseling for medication adherence; providing appropriate training for health care staff to deliver effective information and services for controlling hypertension to patients; enhancing primary health care and specialist services; improving supplies of hypertensive medication in public facilities; taking into account patients' cultural and social background when providing services; and facilitating access and treatment to those who are most vulnerable.

Central venous catheter is commonly utilized as a hemodialysis access in the pediatric population. Long-standing central venous catheters can be complicated by superior vena cava (SVC) stenosis and thrombosis that can rarely present as pleural effusions. We report a case of a 5-year-old boy on chronic hemodialysis who presented with combined pleural and pericardial effusions, which was secondary to catheter induced SVC stenosis. Both the pleural effusion and the pericardial effusion in this patient subsequently improved with the relief of SVC stenosis. This case report highlights the serious complications of SVC stenosis associated with long-standing central venous catheters which is an under-recognized problem in the pediatric population.

A paucity of published data evaluating the outcomes of older patients (age ≥70 years) undergoing revascularization for unprotected left main coronary artery disease is available. We performed aggregate data meta-analyses of the clinical outcomes (all-cause mortality, nonfatal myocardial infarction, stroke, repeat revascularization, and major adverse cardiac and cerebrovascular events at 30 days and 12 and 22 months) in studies comparing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with a mean age of ≥70 years and unprotected left main coronary artery disease. A comprehensive, time-unlimited literature search to January 31, 2013 identified 10 studies with a total of 2,386 patients (PCI, n = 909; CABG, n = 1,477). Summary odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using the random-effects model. The patients in the PCI group were more likely than those in the CABG group to present with acute coronary syndrome (59.6% vs 44.8%, p <0.001). PCI was associated with a shorter hospital stay (4.2 ± 0.8 vs 8.3 ± 0.01 days, p <0.001). No significant differences were found between PCI and CABG for all cause-mortality, nonfatal myocardial infarction, and major adverse cardiac and cerebrovascular events at 30 days and 12 and 22 months. However, PCI was associated with lower rates of stroke at 30 days (OR 0.14, 95% CI 0.02 to 0.76) and 12 months (OR 0.14, 95% CI 0.03 to 0.60) and higher rates of repeat revascularization at 22 months (OR 4.34, 95% CI 2.69 to 7.01). These findings were consistent with the findings from a subgroup analysis of patients aged ≥75 years. In conclusion, older patients (age ≥70 years) with unprotected left main coronary artery disease had comparable rates of all-cause mortality, nonfatal myocardial infarction, and major adverse cardiac and cerebrovascular events after PCI or CABG. The patients undergoing PCI had a shorter hospital stay and lower rates of early stroke; however, they experienced higher repeat revascularization rates at longer term follow-up.

BACKGROUND: There is conflicting data regarding the impact of obesity on morbidity and mortality in patients undergoing isolated coronary artery bypass grafting (CABG). METHODS AND RESULTS: Retrospective cohort analysis of patients who underwent CABG from January 1, 1995, through July 31, 2010 was performed. Patients were classified as obese or non-obese (body mass index ≥ 30.0 kg/m(2) and <30.0 kg/m(2), respectively). The primary outcome was in-hospital mortality. Secondary outcomes included postoperative respiratory failure, postoperative stroke, postoperative myocardial infarction, sternal and leg wound infections, postoperative atrial fibrillation, postoperative ventricular tachycardia, postoperative renal failure and length of hospital stay. Propensity-matched stepwise multivariable logistic regression was performed. Of 13,115 patients, 4,619 (35.2%) were obese. In the propensity-matched logistic regression models (n = 8,442), obesity was not associated with postoperative mortality (odds ratio = 1.13, 95% confidence interval 0.86-1.48). However, obesity was associated with postoperative respiratory failure, postoperative renal insufficiency, sternal wound infection, and leg wound infection. Obesity was also associated with a decreased risk of postoperative bleeding and re-operation from bleeding. CONCLUSIONS: Obesity was associated with an increased risk of postoperative respiratory failure, postoperative renal failure, and surgical site infections. However, obesity was not associated with in-hospital mortality in patients undergoing CABG.
