Determining the suitability of rainwater harvesting for the achievement of sustainable development goals in Wadi Watir, Egypt using GIS techniques.

Scarcity of water has emerged as a major problem globally due to climate change and population growth, especially in semi-arid and arid regions. Egypt is currently experiencing serious water challenges due to its limited water resources. The water challenges require optimal and sustainable water management, which should be linked to sustainable development goals.

Validation of Cardiac Surgery-Associated Neutrophil Gelatinase-Associated Lipocalin Score for Prediction of Cardiac Surgery-Associated Acute Kidney Injury.

Background: The Cardiac Surgery-Associated Neutrophil Gelatinase-Associated Lipocalin (CSA-NGAL) score has been developed to stratify patients with cardiac surgery-associated acute kidney injury (CSA-AKI). Its predictive power needs to be validated to guide clinical decision for such high-risk patients.

Methods: A prospective study was conducted on 637 consecutive adult patients who developed postoperative AKI after cardiac surgery with cardiopulmonary bypass.

Surgery for Pulmonary Parenchymatous Schistosomiasis (Bilharziomas): A 20-Year Single-Centre Experience.

Background: Pulmonary schistosomiasis may complicate urinary or intestinal infestations. Pulmonary pathology is either in the acute or chronic form. The chronic form of the disease may result in granuloma formation.

Bilateral bidirectional Glenn: outcome of off-pump technique.

Objectives: Off-pump bilateral bidirectional Glenn (b-BDG) poses a surgical challenge and may add complexity to the postoperative outcome especially regarding uniformity of the anastomosis and central pulmonary artery growth. Herein, we report early- and mid-term outcomes after off-pump b-BDG without using superior vena cava decompression techniques.

Methods: Ninety-seven consecutive patients, between 2009 and 2014, were included in this prospective study.

On-X versus St Jude Medical Mechanical Prosthesis in mitral position: are we moving forward in design technology?

Background: Continuous effort is still provided in designing optimal artificial heart valves with better hemodynamic function and reduced thromboembolic potential. The question is do we have moved forward toward this goal or not.

Methods: A prospective, randomized comparative study was done on 360 patients scheduled for elective mitral valve replacement.

Single-stage, three-fold repair for Ebstein's anomaly.

Objectives: Favourable outcomes in the repair of Ebstein's anomaly are predicated on tricuspid valve competence, right ventricular function and presence of arrhythmia. We report our experience with a single-stage, three-fold repair of Ebstein's anomaly, namely, cone reconstruction of the tricuspid valve supplemented by bidirectional cavopulmonary anastomosis and right atrial electrocautery maze.

Methods: From 2010 to 2014, 37 consecutive patients with Ebstein's anomaly, median age 17.

Perioperative sildenafil therapy for pulmonary hypertension in infants undergoing congenital cardiac defect closure.

Objectives: Pulmonary hypertension in paediatric patients with ventricular septal defect remains one of the most important determinants of perioperative morbidity and mortality. Sildenafil is an oral, well-tolerated pulmonary vasodilator with few drug interactions. We studied the effect of oral sildenafil, when given before and after surgical closure compared with starting it postoperatively, on the pulmonary artery pressure and patients' outcome.

Cavopulmonary anastomosis without cardiopulmonary bypass.

Objectives: There is an increasing trend to perform the bidirectional superior cavopulmonary (Glenn) anastomosis without cardiopulmonary bypass. In this report, we present our results of off-pump bidirectional Glenn operation done without using a venoatrial shunt to decompress the superior vena cava during clamping. [corrected].
