Gastroprotective potential of Buddleja scordioides Kunth: Effects into the modulation of antioxidant enzymes and inflammation markers in an in vivo model

Ethnopharmacological relevance: A common plant used to treat several gastric disorders is Buddleja scordioides Kunth,commonly known as salvilla. Aim of thes tudy: To detect inflammatory markers,in order to evaluate the gastroprotective potential of salvilla infusions,as this could have beneficial impact on the population exposed to gastric ulcers and colitis. Materials and methods: The present work attempted infusions were prepared with B. scordioides (1% w/w) lyophilized and stored.Total phenolic content and GC–MS analysis were performed. Wistar rats were divided into five groups a negative vehicle control,an indomethacin group,and three experimental groups,named preventive,curative,and suppressive. All rats were sacrificed under deep ether anesthesia(6h)after the last oral administration of indomethacin/infusion.The rat stomachs were promptly excised,weighed,and chilled in ice-cold and 0.9%NaCl.Histological analysis,nitrites quantification and immunodetection assays were done. Results: B.scordioides infusions markedly reduced the visible hemorrhagic lesions induced byindomethacin in rat stomachs,also showed down-regulation of COX2, IL-8 and TNFα and up-regulation of COX-1with a moderate down-regulation of NFkB and lower amount of nitrites.However,this behavior was dependent on the treatment,showing most down-regulation of COX-2,TNFα and IL-8 in the curative treatment;more down-regulation of NF-kB in the preventive treatment;and more up-regulation of COX-1 for the suppressor and preventive treatments. Conclusion: The anti-inflammatory potential of B. scordioides infusions could be related with the presence of polyphenols as quercetin in the infusion and how this one is consumed.

Centenarians and their hearts: a prospective registry with comprehensive geriatric assessment, electrocardiogram, echocardiography, and follow-up

Background Data on the cardiac characteristics of centenarians are scarce. Our aim was to describe electrocardiogram (ECG) and echocardiography in a cohort of centenarians and to correlate them with clinical data. Methods We used prospective multicenter registry of 118 centenarians (28 men) with a mean age of 101.5 ± 1.7 years. Electrocardiogram was performed in 103 subjects (87.3%) and echocardiography in 100 (84.7%). All subjects underwent a follow-up for at least 6 months. Results Centenarians with abnormal ECG were less frequently females (72% vs 93%), had higher rates of previous consumption of tobacco (14% vs 0) and alcohol (24% vs 12%), and scored lower in the perception of health status (6.8 ± 2.0 vs 8.3 ± 6.8). Centenarians with significant abnormalities in echocardiography were less frequently able to walk 6 m (33% vs 54%). Atrial fibrillation/flutter was found in 27 subjects (26%). Mean left ventricular (LV) ejection fraction was 60.0 ± 10.5%. Moderate or severe aortic valve stenosis was found in 16%, mitral valve regurgitation in 15%, and aortic valve regurgitation in 13%. Diastolic dysfunction was assessed in 79 subjects and was present in 55 (69.6%). Katz index and LV dilation were independently associated with the ability to walk 6 m. Age, Charlson and Katz indexes, and the presence of significant abnormalities in echocardiography were associated with mortality. Conclusions Centenarians have frequent ECG alterations and abnormalities in echocardiography. More than one fifth has atrial fibrillation, and most have diastolic dysfunction. Left ventricular dilation was associated with the ability to walk 6 m. Significant abnormalities in echocardiography were associated with mortality.

Does multiparametric MRI increase Oncologic outcomes in prostate cancer?

The purpose of this study is to compare the 4-year biochemical disease-free survival (BDFS) of patients with prostate cancer (PCa) staged according to multiparametric MRI (mpMRI) and treated with radical prostatectomy (RP) versus intensity-modulated radiation therapy (IMRT) ≥76 Gy ± hormonal therapy (HT).
