Introduction: Higher levels of kidney-injury molecule-1 (KIM-1) measured in urine are associated with presence and progression of acute renal disease. A recent study reported similar results for KIM-1 measured in blood. Hypothesis: We hypothesized that KIM-1 measured in stored serum from middle-aged men who participated in the Multiple Risk Factor Intervention Trial (MRFIT) would differentiate very long-term risk of fatal CHD vs. survival to a mean age of 80 over approximately 30 year follow-up. Methods: We conducted a nested case-control study within MRFIT, which in 1973-76 randomized 12,866 high risk but CVD free men ages 35-57 to risk factor intervention vs. usual care. Serum samples were collected at baseline and stored for future use. The trial concluded in 1982 but long-term mortality follow-up was ascertained through 2005 using the National Death Index. From MRFIT participants with stored serum from baseline, we sampled 100 men who died of CHD (mean age 47.3 at baseline and 73.9 at death), and 100 men who survived to 2005 (mean age =48.4 at baseline and 80.1 in 2005.) KIM-1 was assayed from stored serum samples using high sensitivity single-molecule counting technology (Erenna ® Immunoassay System, Singulex), with limit of detection (LoD)=0.5 pg/ml, and lower limit of quantification (LLoQ)=2.0 pg/ml. Results were compared between cases and controls using Wilcoxon rank tests and logistic regression. Results: Inter-assay %CVs were 8%. Median KIM-1 was higher for smokers vs. non-smokers and for men with vs. without hypertension, but was not associated with high cholesterol. KIM-1 was significantly higher in cases (183 pg/ml (IQR: 137-239) versus controls, (161 pg/ml (IQR:109-212), p=0.03; OR (95%CI)for Q4 versus Q1 was 2.26 (1.02 - 5.02) Adjusted for age and smoking the OR(95%CI) of fatal CHD for Q4 vs. Q1 was 2.34 (1.02- 5.37), and further adjusted for diastolic BP and serum cholesterol at baseline, was 2.0 (95% CI: 0.8-4.7). Conclusions: Higher serum KIM-1 levels at midlife were associated with a ∼2-fold increased risk of fatal CHD vs. survival over ∼30 years of follow-up. This is the first report of a longitudinal association of circulating KIM-1 levels with fatal CHD in long-term follow-up.

Abstract Background The potential relationship between a mild acute kidney injury (AKI) observed in the immediate postoperative period after major surgery and its effect on long term renal function remains poorly defined. According to the “Kidney Disease: Improving Global Outcomes” (KDIGO) classification, a mild injury corresponds to a KIDIGO stage 1, characterized by an increase in creatinine of at least 0.3 mg/dl within a 48-h window or 1.5 to 1.9 times the baseline level within the first week post-surgery. We tested the hypothesis that patients who underwent intermediate-to high-risk abdominal surgery and developed mild AKI in the following days would be at an increased risk of long-term renal injury compared to patients with no postoperative AKI. Methods All consecutive adult patients with a plasma creatinine value ≤1.5 mg/dl who underwent intermediate-to high-risk abdominal surgery between 2014 and 2019 and who had at least three recorded creatinine measurements (before surgery, during the first seven postoperative days, and at long-term follow up [6 months-2 years]) were included. AKI was defined using a “modified” (without urine output criteria) KDIGO classification as mild (stage 1 characterised by an increase in creatinine of > 0.3 mg/dl within 48-h or 1.5–1.9 times baseline) or moderate-to-severe (stage 2–3 characterised by increase in creatinine 2 to 3 times baseline or to ≥4.0 mg/dl). The exposure (postoperative kidney injury) and outcome (long-term renal injury) were defined and staged according to the same KDIGO initiative criteria. Development of long-term renal injury was compared in patients with and without postoperative AKI. Results Among the 815 patients included, 109 (13%) had postoperative AKI (81 mild and 28 moderate-to-severe). The median long-term follow-up was 360, 354 and 353 days for the three groups respectively (P = 0.2). Patients who developed mild AKI had a higher risk of long-term renal injury than those who did not (odds ratio 3.1 [95%CI 1.7–5.5]; p < 0.001). In multivariable analysis, mild postoperative AKI was independently associated with an increased risk of developing long-term renal injury (adjusted odds ratio 4.5 [95%CI 1.8–11.4]; p = 0.002). Conclusions Mild AKI after intermediate-to high-risk abdominal surgery is associated with a higher risk of long-term renal injury 1 y after surgery.

AbstractTakotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

SummaryWhether atrial fibrillation (AF) is associated with an increased risk of venous thromboembolism (VTE) remains controversial. From Longitudinal Health Insurance Database 2000 (LHID2000), we identified 11,458 patients newly diagnosed with AF. The comparison group comprised 45,637 patients without AF. Both cohorts were followed up to measure the incidence of deep-vein thrombosis (DVT) and pulmonary embolism (PE). Univariable and multivariable competing-risks regression model and Kaplan-Meier analyses with the use of Aelon-Johansen estimator were used to measure the differences of cumulative incidences of DVT and PE, respectively. The overall incidence rates (per 1,000 person-years) of DVT and PE between the AF group and non-AF groups were 2.69 vs 1.12 (crude hazard ratio [HR] = 1.92; 95 % confidence interval [CI] = 1.54-2.39), 1.55 vs 0.46 (crude HR = 2.68; 95 % CI = 1.97-3.64), respectively. The baseline demographics indicated that the members of the AF group demonstrated a significantly older age and higher proportions of comorbidities than non-AF group. After adjusting for age, sex, and comorbidities, the risks of DVT and PE remained significantly elevated in the AF group compared with the non-AF group (adjusted HR = 1.74; 95 %CI = 1.36-2.24, adjusted HR = 2.18; 95 %CI = 1.51-3.15, respectively). The Kaplan-Meier curve with the use of Aelon-Johansen estimator indicated that the cumulative incidences of DVT and PE were both more significantly elevated in the AF group than in the non-AF group after a long-term follow-up period (p<0.01). In conclusion, the presence of AF is associated with increased risk of VTE after a long-term follow-up period.

Acute kidney injury (AKI) is under-recognised in children and neonates. It is associated with increased mortality and morbidity along with an increased incidence of chronic kidney disease in adulthood. It is important that paediatricians are able to recognise AKI quickly, enabling prompt treatment of reversible causes. In this article, we demonstrate an approach to recognising paediatric AKI, cessation of nephrotoxic medication, appropriate investigations and the importance of accurately assessing fluid status. The mainstay of treatment is attempting to mimic the kidneys ability to provide electrolyte and fluid homeostasis; this requires close observation and careful fluid management. We discuss referral to paediatric nephrology and the importance of long-term follow-up. We present an approach to AKI through case-presentation.

Abstract Objectives Nutritional rickets (NR) is still an important problem and one which increasing influxes of immigrants are further exacerbating. This study evaluated cases of mostly immigrant children followed up with diagnoses of NR in our pediatric endocrinology clinic. Methods Details of 20 cases diagnosed with NR between 2017 and 2020 were retrieved from file records. Results Twenty (11 male) cases were included in the study. Three (15%) were Turkish nationals and the others (85%) were immigrants. Hypocalcemia and hypophosphatemia were detected in 17 and 13, respectively. Alkaline phosphatase (ALP) values were normal in two cases, while ALP and parathyroid hormone (PTH) values were elevated in all other cases, and PTH levels were very high (473.64 ± 197.05 pg/mL). 25-hydroxyvitamin D levels were below 20 ng/mL in all cases. Patients with NR received high-dose long-term vitamin D or stoss therapy. Six patients failed to attend long-term follow-up, while PTH and ALP levels and clinical findings improved at long-term follow-up in the other 14 cases. Conclusions The elevated PTH levels suggest only the most severe cases of NR presented to our clinic. Clinically evident NR is therefore only the tip of the iceberg, and the true burden of subclinical rickets and osteomalacia remains unidentified. Public health policies should therefore focus on universal vitamin D supplementation and adequate dietary calcium provision, their integration into child surveillance programs, adequate advice and support to ensure normal nutrition, exposure to sunlight, and informing families of the increased risk not only for resident populations but also for refugee and immigrant children.

Background: Increasing penetration of high spatial resolution cardiovascular magnetic resonance (CMR) imaging into routine cardiovascular practice has resulted in more frequent identification of a subset of hypertrophic cardiomyopathy (HCM) patients with thin-walled, scarred left ventricular (LV) apical aneurysms. Prior experience involved relatively small numbers of patients with short follow-up and therefore the risk associated with this subgroup remains incompletely defined. Therefore, we assembled a large HCM cohort with LV apical aneurysms and long-term follow-up in order to clarify clinical course and prognosis. Methods and Results: Of 2,400 HCM patients, 60 (2.5%) were identified by CMR with LV apical aneurysm, 24 to 86 years of age, including 19 (32%) <45 years old; 70% male, and followed for 5.6 ± 3.5 years. Over the follow-up period, 24 patients experienced 31 adverse disease-related complications including: appropriate implantable cardioverter-defibrillator discharge for VT/VF (n=11), received or listed for heart transplant (n=6), heart failure death (n=5), nonfatal thromboembolic events (n=4), resuscitated out-of-hospital cardiac arrest (n=3), and sudden death (n=2). In addition, an intracavitary thrombus was identified in the apical aneurysm in 9 patients without a thromboembolic history. Combined HCM-related death and aborted life threatening event rate was 8.6% per year, nearly 6-fold greater than the 1.5% annual mortality rate reported in the general HCM population. Conclusions: Patients with LV apical aneurysms represent a high-risk subgroup within the diverse HCM spectrum, associated with substantial increased risk for disease-related morbidity and mortality, including advanced heart failure, thromboembolic stroke and sudden death. Identification of this unique HCM phenotype should prompt consideration for primary prevention ICD, and anticoagulation for stroke prophylaxis.

Background: The Ross operation is considered the procedure of choice for aortic valve replacement in children and represents an attractive alternative in selected young adults. However, long term follow-up has demonstrated high rates of pulmonary autograft failure raising concern regarding its clinical utility. We analyze long term outcomes of our Ross series, focusing on predictors of autograft failure. Methods: Between 1991 and 2006, 260 consecutive patients underwent Ross operation. Mean age was 35±15 years (range: 1 day to 64 years) and 75% were male. The technique for autograft implantation was a full root replacement in 70% (n=183), inclusion cylinder in 28% (n=73) and subcoronary in 2% (n=4). Right ventricular outflow tract (RVOT) was reconstructed with a pulmonary homograft in 94% (n=245) and with a xenograft in 6% (n=15). Mean clinical follow-up (97% complete) was 97±46 months (13 to 196 months). Echocardiographic follow-up was available in 234 survivors (94%). Results: Hospital mortality was 1.9% (n=5) and 7 patients died during follow-up (3 non cardiac). Twelve year overall survival was 93±4% and freedom from autograft reoperation and from autograft valve replacement was 83±7% and 94±5% respectively. Twenty-five patients (9.6%) underwent autograft reoperation either for insufficiency (n=8), autograft or ascending aorta dilatation (n=6), or both (n=11) with no mortality. In 76% (n=19) of these patients, the autograft valve was preserved. Predictors for autograft dilatation (≥45 mm) were preoperative aortic insufficiency and full root technique. RVOT reintervention was required in 10 (4%) patients (reoperations n=7, balloon dilatation n=3). Twelve year freedom from RVOT reintervention was 95±4. Twelve year freedom from thrombo-embolic and bleeding events was 99±1% (1 stroke, 1 TIA, 1 bleeding event). Conclusions: This long terms study confirms the excellent survival after Ross operation with an extremely low rate of thrombo-embolic and bleeding events. Autograft reoperation rate remains acceptable. Full root technique is associated with increased risk of autograft dilatation, and should be avoided especially in adults with preoperative aortic insufficiency. Autograft valve preservation is feasible in autograft reoperation.
