Pediatric Renal Admission: Clinical Spectrum and Outcome, the Experience of Two Semi-urban, Secondary Hospitals in Cameroon

Background and aim: There is limited data on renal diseases in paediatric admissions in Cameroon. The aim was to describe the clinical spectrum and outcomes of renal diseases among admitted children in two regional hospitals in Cameroon.   Materials and Methods: we reviewed archived records of children admitted with renal disease from the 1st January 2017 to 31st December 2019 for renal diseases and outcomes. Results: In all, 148 (1.98%) of the 7457 admitted children had a renal disease. Their median age was 7.5 years (IQR 4-12) and 63.5% were females with 32.4% less than 5years. Urinary tract infection (51.4%), Acute kidney injury (21.6%), Nephrotic syndrome (12.2%), chronic kidney disease (12.2%) and renal mass (2.6%) were frequently described. Complicated UTI was observed in 9.2% of children with UTI whereas initiation of corticotherapy (83.3%) was the most common reason for admission in children with nephrotic syndrome. Malaria (40.6%) and sepsis (40.6%) were the most common aetiology of AKI whereas chronic GN was the most common aetiology of CKD. Out of the 32 children with AKI, 50% had an indication for dialysis with 87.5% having access to the therapy. Nine (75%) of the 12 children with non-dialysed CKD-5 needed dialysis with 55.5% (5/9) having access to it. Out of the 148 children, 07 (4.7%) died. Deaths were due to AKI and CKD; with specific death rates of 12.5% and 16.7% respectively.   Conclusion: Renal diseases are uncommon among admitted children. Overall in-hospital mortality was low

Expert recommendations on the assessment of wall shear stress in human coronary arteries : existing methodologies, technical considerations, and clinical applications

The aim of this manuscript is to provide guidelines for appropriate use of CFD to obtain reproducible and reliable wall shear stress maps in native and instrumented human coronary arteries. The outcome of CFD heavily depends on the quality of the input data, which include vessel geometrical data, proper boundary conditions, and material models. Available methodologies to reconstruct coronary artery anatomy are discussed in ‘Imaging coronary arteries: a brief review’ section. Computational procedures implemented to simulate blood flow in native coronary arteries are presented in ‘Wall shear stress in native arteries’ section. The effect of including different geometrical scales due to the presence of stent struts in instrumented arteries is highlighted in ‘Wall shear stress in stents’ section. The clinical implications are discussed in ‘Clinical applications’ section, and concluding remarks are presented in ‘Concluding remarks’ section

Biomechanical Modeling to Improve Coronary Artery Bifurcation Stenting: Expert Review Document on Techniques and Clinical Implementation

Treatment of coronary bifurcation lesions remains an ongoing challenge for interventional cardiologists. Stenting of coronary bifurcations carries higher risk for in-stent restenosis, stent thrombosis, and recurrent clinical events. This review summarizes the current evidence regarding application and use of biomechanical modeling in the study of stent properties, local flow dynamics, and outcomes after percutaneous coronary interventions in bifurcation lesions. Biomechanical modeling of bifurcation stenting involves computational simulations and in vitro bench testing using subject-specific arterial geometries obtained from in vivo imaging. Biomechanical modeling has the potential to optimize stenting strategies and stent design, thereby reducing adverse outcomes. Large-scale clinical studies are needed to establish the translation of pre-clinical findings to the clinical arena
