The selection of an appropriate antimicrobial is a challenging task for clinicians. Kirby-Bauer disk diffusion method one the most widely practiced susceptibility tests (AST). It affected by many factors among which are media used. Mueller-Hinton agar (MHA) standard medium recommended in guidelines. However, these guidelines not strictly adhered to some developing countries. Validation AST results on nutrient (NA) used as substitute MHA microbiology laboratories Alexandria, Egypt. A total...
The single ventricle patient population comprises the most complex cohort presenting to cardiac transplant team, in terms of demographics, anatomic substrate, and unique physiology. It is also rapidly growing diagnostic group for heart transplantation. In this manuscript, we aim describe changing landscape transplantation conditions through reflection on our own institution's practice experience, alongside contemporary literature review. Single patients are heterogeneous age, diagnosis...
Objectives Adults with congenital heart disease (ACHD) are a growing group end-stage failure. We aim to describe the outcomes of ACHD patients undergoing assessment for orthotopic transplant (OHT). Methods Case notes consecutive (>16 years) assessed OHT between 2000 and 2016 at our centre were reviewed. Decision outcome reported as 2017. Data analysed in three groups: systemic left ventricle (LV), right (RV) single (SV). Results 196 (31.8 years, 27% LV, 29% RV, 44% SV). 89 (45%) listed 67...
To identify the key contributors to postoperative mortality in patients undergoing orthotopic heart transplantation (OHT) for late Fontan failure.This retrospective review of failing who underwent OHT our tertiary care center between 2007 and 2019 included adult with congenital disease single ventricle physiology were palliated a circulation >1 year. We excluded combined heart-liver transplantation.The study cohort comprised 31 patients, including 18 males (58.1%), mean weight 58.4 kg,...
Background: Pulmonary autograft failure remains a cause of reoperation following the Ross procedure. The aim this study is to describe our evolving approach reoperations. Methods: Retrospective all patients who underwent pulmonary procedure between June 1997 and July 2022. Results: Two-hundred thirty-five procedures were performed. Thirty-six (15%) plus one referral an at median 7.8 years (IQR 4.6-13.6). main indication was: neoaortic root dilatation associated with mild/moderate (n = 12) or...
With the scarcity of organs, a durable, reliable ventricular assist device (VAD) is required. The Berlin Heart EXCOR ® (BH) remains most established VAD in paediatric population. Implantable continuous flow (CF) VADs have been introduced to field with encouraging early results. In this study, we compared results newly CF (HeartWare [HVAD] ) matched group BH recipients.The study included patients aged <16 years who received mechanical left (LVAD) support between December 2005 and January...
Objective Norwood and hybrid procedure are two options available for initial palliation of patients with hypoplastic left heart syndrome (HLHS). Our study aimed to assess potential differences in right ventricular (RV) function pulmonary artery dimensions using cardiac magnetic resonance (CMR) survivors HLHS. Methods 42 (mean age 2.4±0.8) 44 2.0±1.0 years) were evaluated by CMR after stage II prior planned Fontan completion. Initial I was performed a modified Blalock-Taussig shunt, while the...
Abstract This is a report of unique DCD paediatric heart transplant whereby normothermic regional perfusion was used to assess function after death followed by ex situ the graft during transportation from donor recipient hospitals. The 9‐year‐old boy weighing 84 kg. 7‐year‐old with failing Fontan circulation and weighed 23 It an ABO‐compatible transplantation. reperfused assessed using portable transportation. orthotopic transplantation successful good no evidence rejection on endomyocardial...
Branch pulmonary artery (BPA) size is one of the factors that influence efficacy Fontan circulation. Central stenosis and small left (LPA) are well-known problems following Norwood palliation for hypoplastic heart syndrome (HLHS). We investigated anatomical technical may stand behind these problems.A total 47 consecutive patients were included in study. All had complete magnetic resonance imaging (MRI) study pre-second-stage palliation. Measurements taken using a first-pass 3D angiography...
Background: Hypoplastic left heart syndrome (HLHS) with either intact atrial septum (IS) or highly restrictive interatrial communication (HRIC) is associated poor survival. Immediate postpartum access to cardiac therapy and timely decompression (LAD) are paramount a successful outcome. We describe herein our evolving approach LAD report interstage longer-term results. Methods: retrospectively identified neonates HLHS IS/HRIC requiring between 2005 2019. All babies had prenatal/postnatal...
Research on guest satisfaction with green practices in hotels has generated mixed results; some studies have shown a positive relationship and others negative relationship.To reconcile these two opposing views, the mediating effects of perceived motives, attributes was examined as potential psychological mechanisms explaining guests' reactions to hotels.Besides, moderating role service outcomes influencing initiatives investigated.Results indicate that when delivery is successful, higher for...
Purpose – To explore the effect of 3D printed food characteristics on Value-Attitude-Behavioral model in Egyptian restaurants.Design/methodology/approach Using a quantitative design, self-administrated questionnaire was conducted with customers who eat at restaurants.Findings Four food: health, fun, creativity and natural content were explored. The primary result identified have positive significant hedonic value. Moreover, utilitarian perceived values an impact customer attitudes toward...
Abstract Objectives We aimed to compare the procedural and mid-term performance of a specifically designed self-expanding stent with balloon-expandable stents in patients undergoing hybrid palliation for hypoplastic left heart syndrome its variants. Background The lack has led off-label use coronary, biliary, or peripheral neonatal ductus arteriosus. Recently, stent, syndrome, become available. Methods carried out retrospective cohort comparison 69 neonates who underwent ductal stenting from...
Ventricular assist device (VAD) for systemic right ventricular (RV) failure patients post-atrial switch, transposition of the great arteries (TGA), and those with congenitally corrected TGA has proven useful to reduce transpulmonary gradient bridge-to-transplantation. The purpose this study is describe our experience VAD in RV move towards concomitant tricuspid valve replacement (TVR).This a single-centre retrospective consecutive adult receiving HeartWare between 2010 2019. From 2017, TVR...
Our goal was to present 2 decades of our experience with the Ross procedure and its sequential modifications, adopted since 2010, improve reoperation rate.We performed a single-centre, retrospective review database information medical notes about implantation technique: freestanding root. We compared era 1 (1997-2009) (2010-2019).Between 1997 2019, total 214 procedures were (71% men, median age 24 years) [interquartile range (IQR) 15-38]. Of these, 87% had various forms congenital-dysplastic...
Abstract Background Hypertension following primary coarctation repair affects up to a third of subjects. A number studies suggest that future hypertension risk is reduced if performed at younger age. Objectives The objective this study was evaluate the medical treatment for depending on age repair. Methods This carried out tertiary paediatric cardiology referral centre. Retrospective database evaluation children aged <16 years undergoing surgical between October, 2005 and 2014 out....
Sugar beet (Beta vulgaris subsp.vulgaris) is a biennial crop taxonomically affiliated with the Amaranthaceae family (Schwichtenberg et al., 2016;Mukherjee and Gantait 2023).it regarded as crucial industrial that substantially participates in world's supply of sugar.On global scale, sugar second main important sugarproducing after sugarcane, is, therefore, it significant crop.As result its short duration (5 to 6 months) also has higher sucrose content (14-20%) than sugarcane (10-12%), high...
Abstract Objective Mitral valve anatomy has a significant impact on potential surgical options for patients with hypoplastic or borderline left ventricle. Papillary muscle morphology is major component regarding this aspect. The purpose of study was to use cardiac magnetic resonance describe the differences in papillary between normal, borderline, and ventricles. Methods We carried out retrospective, observational children (median age 5.36 years) normal (n=30), (n=22), (n=13) Borderline...
