AimTo identify predictors of 3-month mortality after heart transplantation in a Croatian academic center.MethodsA retrospective review of institutional database identified 117 heart transplantations from January 2008 to July 2014. Two children <14 years were excluded from the study. The remaining 115 patients were dichotomized into survivors and non-survivors adjudicated at 3-months postoperatively, and their demographic, clinical, and longitudinal hemodynamic data were analyzed.Results3-month survival after heart transplantation was 86%. Non-survivors were older (59 ± 8 vs 50 ± 14 years, P = 0.009), more likely to have previous cardiac surgery (44% vs 19%; odds ratio [OR] 3.28, 95% confidence interval [CI] 1.08-9.90; P = 0.029), lower body mass index (BMI) (25 ± 4 vs 28 ± 2 kg/m2, P = 0.001), and be diabetics (44% vs 23%; OR 2.57, 95% CI 0.86-7.66; P = 0.083). Creatinine clearance was marginally superior among survivors (59 ± 19 vs 48 ± 20 mL/min, P = 0.059). Donor age and sex did not affect outcomes. Non-survivors were more likely to have had ischemic cardiomyopathy (69% vs 32%, P = 0.010). Postoperative utilization of epinephrine as a second line inotropic agent was a strong predictor of mortality (63% vs 7%; OR 21.91; 95% CI 6.15-78.06; P < 0.001). Serum lactate concentrations were consistently higher among non-survivors, with the difference being most pronounced 2 hours after cardiopulmonary bypass (9.8 ± 3.5 vs 5.2 ± 3.2 mmol/L, P < 0.001). The donor hearts exhibited inferior early hemodynamics in non-survivors (cardiac index 3.0 ± 1.0 vs 4.0 ± 1.1 L/min/m2, P = 0.001), stroke volume (49 ± 24 vs 59 ± 19 mL, P = 0.063), and left and right ventricular stroke work indices (18 ± 8 vs 30 ± 11 g/beat/m2, P < 0.001 and 5 ± 3 vs 7 ± 4 g/beat/m2, P = 0.060, respectively). Non-survivors were more likely to require postoperative re-sternotomy (50% vs 12%; OR 7.25, 95% CI 2.29-22.92; P < 0.001), renal replacement therapy (RRT) (69% vs 9%; OR 22.00, 95% CI 6.24-77.54; P < 0.001), and mechanical circulatory assistance (MCS) (44% vs 5%; OR 14.62, 95% CI 3.84-55.62; P < 0.001). Binary logistic regression revealed recipient age (P = 0.024), serum lactates 2 hours after CPB (P = 0.007), and epinephrine use on postoperative day 1 (P = 0.007) to be independently associated with 3-month mortality.ConclusionPretransplant predictors of adverse outcome after heart transplantation were recipient age, lower BMI, ischemic cardiomyopathy, reoperation and diabetes. Postoperative predictors of mortality were inferior donor heart hemodynamics, epinephrine use, and serum lactate concentrations. Non-survivors were more likely to require re-sternotomy, MCS, and RRT.

Introduction Current practice guidelines in gastroesophageal reflux disease (GERD) often require invasive diagnostic testing. Objective The aim of the present study was to evaluate the significance of extra-esophageal symptoms and reliability of a screening risk score that is simple to use. Methods A longitudinal retrospective single-institution cohort study. Setting: A university clinical hospital tertiary referral center. The present study enrolled pediatric patients with symptoms suggestive of GERD: epigastric pain, occasional nausea, regurgitation, tasting acid in the oral cavity, chronic cough, hoarseness of voice, frequent throat clearing. The patients underwent 24-hour esophageal pH monitoring and fiber-optic laryngoscopy. The correlations between the local findings, anamnestic and objective measurement data were analyzed. Results The present study evaluated 89 pediatric patients. Patients with asthma presented significantly more often with adjoining gastrointestinal symptoms (p = 0.0472). Patients that were obese were linked to a higher rate of reports of gastrointestinal symptoms (p = 0.0495). After the patients had been assigned to newly developed risk groups, obesity showed to be significantly more frequent in patients placed in higher risk groups (p < 0.0001) for a positive GERD diagnosis. Conclusion Patients with leading symptoms of asthma presented significantly more often with adjoining gastrointestinal symptoms. Obesity showed to be significantly more frequent in patients placed in higher risk groups for a positive GERD diagnosis.
