BACKGROUND Vascular diseases, encompassing coronary heart disease (CHD), cerebrovascular disease (CVD), and peripheral artery disease (PAD), are leading causes of the global mortality and morbidity burdens. Our objective was to evaluate the temporal trends in the burden of vascular diseases in the province of Quebec from 2000 to 2015. METHODS We identified subjects aged ≥ 20 years with vascular diseases in the Quebec Integrated Chronic Disease Surveillance System (a combination of 5 provincial health administrative datasets). We identified Quebecers with CHD, CVD, or PAD by tracking codes identifying vascular diseases (and interventions for CHD) in the hospitalization datasets. We used the 2011 Quebec standard population for age standardization. RESULTS In 2015, the crude prevalence of vascular diseases was 7.3% (n = 473,305), and the all-cause crude mortality rate was 6.6% (n = 31,320). Age-standardized prevalence of vascular diseases increased relatively by 21.4% between 2000 (5.6%; 99% confidence interval [CI], 5.5-5.6) and 2015 (6.8%; 99% CI, 6.7-6.8), whereas the age-standardized incidence and mortality rates showed relative decreases of 46.2% and 32.6%, respectively. PAD and CVD had lower prevalence and incidence but higher mortality than CHD. Tertiapin-Q concentration Most patients with CHD only had this vascular disease in contrast to patients with PAD who generally had diseases involving more than 1 vascular bed. CHD only and CHD with PAD ranked first and second, respectively, in mortality burdens. CONCLUSIONS During the last decade, the age-standardized incidence and mortality rate of vascular diseases declined, but their prevalence increased with the overall burden of vascular diseases remaining substantial in Quebec, Canada. BACKGROUND Calyceal diverticula (CD) are abnormally dilated calyces caused by a narrowed infundibulum. Although rare, with incidence rates previously reported between 0.21% and 0.45%, CD pose diagnostic dilemmas in children as they mimic other cystic lesions of the kidney with different etiologies. Calyceal diverticula can become symptomatic if they become a locus for infections and stone formation, and the optimal treatment strategy is currently undefined. OBJECTIVE The aim of the study is to present a large series of consecutive cases of pediatric CD and investigate the authors' hypothesis that CDs are more common than previously reported, size of the lesion drives intervention, and laparoscopic ablation is the most effective intervention. STUDY DESIGN The authors conducted an observational case-control survey by reviewing all cases of pediatric CD through a prospectively maintained database of renal cystic lesions at their institution between 2012 and 2018. They analyzed the clinical and radiological presef ureteroscopic interventions required multiple sessions (11/17, 65%, median = 2 major procedures) to achieve resolution, whereas none in the laparoscopic group required a second procedure. There were a total of 30 ureteroscopic and 8 laparoscopic approaches. CONCLUSIONS The authors demonstrate that CD comprise at least 5% of cystic lesions and that CD size and pain at presentation predict intervention in 60% of children diagnosed at their institution. Laparoscopic ablation is the optimal treatment and has significantly higher success rates than the ureteroscopic approach. INTRODUCTION Ureteropelvic junction obstruction (UPJO) is one of the most common causes of hydronephrosis in pediatric populations. Many need surgical intervention. The aim of surgery is preserving renal function and reducing symptoms such as urinary tract infections and pain. OBJECTIVES The objectives were to evaluate differential renal function (DRF) in infants and children after surgery for UPJO and to identify factors predicting postoperative improvement. The difference in outcomes between patients with antenatal hydronephrosis and those diagnosed later was evaluated. STUDY DESIGN A total of 85 children (63 boys and 22 girls) aged 0-16 years, treated for UPJO with dismembered pyeloplasty, were followed up as per a structured protocol including ultrasounds and renal scans (MAG-3) pre-operatively and three and 18 months postoperatively. Five children with bilateral or single kidney UPJO were excluded. Patient records were retrospectively reviewed, and the patients were grouped as per prenatal (group 1, n = , and high APD (odds ratio [OR] = 1.1, P = 0.0023), antenatal diagnosis (OR = 0.23, P = 0.048), and low pre-operative DRF (OR = 0.90, P = 0.0045) built the best model of independent factors predicting improvement in DRF in multivariable analyses (Summary Figure). DISCUSSION The limitation of the study is that it is retrospective, but it has the advantage of a uniform follow-up protocol, including patients from a five-year period, with few lost to follow-up. The results can be of interest in evaluating factors of importance for predicting recovery of function in obstructive uropathies in children. CONCLUSION The majority of children had preserved or improved function after surgery for UPJO. Those with an antenatal diagnosis displayed a greater ability to catch up in DRF, and high APD, antenatal diagnosis, and low pre-operative DRF were independent predictive factors of an improvement in renal function after pyeloplasty. Cell-penetrating peptides (CPPs) are an attractive tool for delivering membrane-impermeable compounds, including anionic biomacromolecules such as DNA and RNA, into living cells. Amphipathic helical peptides composed of hydrophobic amino acids and cationic amino acids are typical CPPs. In the current study, we designed amphipathic helical 12-mer peptides containing α,α-disubstituted α-amino acids (dAAs), which are known to stabilize peptide secondary structures. The dominant secondary structures of peptides in aqueous solution differed according to the introduced dAAs. Peptides containing hydrophobic dAAs and adopting a helical structure exhibited a good cell-penetrating ability. As an application of amphipathic helical peptides, small interfering RNA (siRNA) delivery into living human hepatoma cells was investigated. One of the peptides containing dAAs dipropylglycine formed stable complexes with siRNA at appropriate zeta-potential and size for intracellular siRNA delivery. This peptide showed effective RNA interference efficiency at short peptide length and low concentrations of peptide and siRNA.
