1MicroRNAs in pathogenesis of breast cancer:Implications in diagnosis and treatment显示文摘MicroR NAs(miR NAs) are small non-coding RNAs generated by a two-step complex process and are post transcriptional negative regulators of their target m RNAs. Dysregulation of many of these miR NAs has been associated with tumorigenesis in various cancers including breast cancer. Aberrantly high expression of specific mi RNAs in breast cancer cells is demonstrated to be linked with inhibition of tumor suppressor genes and promote tumorigenesis. They are classified as oncogenic miR NAs. However, the tumor suppressor miR NAs are downregulated in breast cancer cells, since their major targets are oncogenic m RNAs. Understanding mechanism of action of specific miR NAs in breast cancer cells can be utilized to develop newer anti-cancer therapies. Recently, newer techniques are also developed to detect abundance of specific miR NA in the blood plasma samples and can be used in early diagnosis or prognosis in breast cancer. In this review article, we have discussed several mi RNAs dysregulated in breast cancer and their therapeutic potential.Nirav R Shah Hexin Chen 2014World Journal of Clinical Oncology2014,5,2:8
2Photodynamic therapy vs radiofrequency ablation for Barrett's dysplasia: Efficacy,safety and cost-comparison显示文摘AIM:To compare effectiveness,safety,and cost of photodynamic therapy(PDT)and radiofrequency ablation(RFA)in treatment of Barrett’s dysplasia(BD).METHODS:Consecutive case series of patients undergoing either PDT or RFA treatment at single center by a single investigator were compared.Thirty-three patients with high-grade dysplasia(HGD)had treatment with porfimer sodium photosensitzer and 630 nm laser(130 J/cm),with maximum of 3 treatment sessions.Fifty-three patients with BD(47 with low-grade dysplasia-LGD,6 with HGD)had step-wise circumferential and focal ablation using the HALO system with maximum of 4 treatment sessions.Both groups received proton pump inhibitors twice daily.Endoscopic biopsies were acquired at 2 and 12 mo after enrollment,with 4-quadrant biopsies every 1 cm of the original BE extent.A complete histological resolution response of BD(CR-D)was defined as all biopsies at the last endoscopy session negative for BD.Fisher’s exact test was used to assess differences between the two study groups for primary outcomes.For all outcomes,a two-sided P value of less than 0.05 was considered to indicate statistical significance.RESULTS:Thirty(91%)PDT patients and 39(74%)RFA were men(P=0.05).The mean age was 70.7±12.2 and 65.4±12.7(P=0.10)year and mean length of BE was 5.4±3.2 cm and 5.7±3.2 cm(P=0.53)for PDT and RFA patients,respectively.The CR-D was(18/33)54.5%with PDT vs(47/53)88.7%with RFA(P=0.001).One patient with PDT had an esophageal perforation and was managed with non-surgical measures and no perforation was seen with RFA.PDT was five times more costly than RFA at our institution.The two groups were not randomized and had different BD grading are the limitations of the study.CONCLUSION:In our experience,RFA had higher rate of CR-D without any serious adverse events and was less costly than PDT for endoscopic treatment of BD.Atilla Ertan Irum Zaheer Arlene M Correa Nirav Thosani Shanda H Blackmon 2013World Journal of Gastroenterology2013,19,41:7

5Reduced incidence and mortality from colorectal cancer with flexible-sigmoidoscopy screening: A meta-analysis显示文摘AIM:To conduct a systematic review and meta-analysis of published population-based randomized controlled trials(RCTs).METHODS:RCTs evaluating the difference in mortality and incidence of colorectal cancer(CRC)between a screening flexible sigmoidoscopy(FS)group and control group(not assigned to screening FS)with a minimum 5 years median follow-up were identified by a search of MEDLINE and EMBASE databases and the Cochrane Central Register for Controlled Trials through August 2013.Random effects model was used for meta-analysis.RESULTS:Four RCTs with a total of 165659 patientsin the FS group and 249707 patients in the control group were included in meta-analysis.Intention-totreat analysis showed that there was a 22%risk reduction in total incidence of CRC(RR=0.78,95%CI:0.74-0.83),31%in distal CRC incidence(RR=0.69,95%CI:0.63-0.75),and 9%in proximal CRC incidence(RR=0.91,95%CI:0.83-0.99).Those who underwent screening FS were 18%less likely to be diagnosed with advanced CRC(OR=0.82,95%CI:0.71-0.94).There was a 28%risk reduction in overall CRC mortality(RR=0.72,95%CI:0.65-0.80)and 43%in distal CRC mortality(RR=0.57,95%CI:0.45-0.72).CONCLUSION:This meta-analysis suggests that screening FS can reduce the incidence of proximal and distal CRC and mortality from distal CRC along with reduction in diagnosis of advanced CRC.Jennifer Shroff Nirav Thosani Sachin Batra Harminder Singh Sushovan Guha 2014World Journal of Gastroenterology2014,20,48:3
6Is Entresto good for the brain?显示文摘The main stay pharmacotherapy for heart failure(HF) is targeted towards rennin-angiotensin-aldosterone(RAAS) and neprilysin pathways(NP). Both therapeutic strategies decreases morbidity and mortality but also carry considerable adverse effects. This review of the literature highlights the new generation of HF drug, sacubitril-valsartan(SV), trade name Entresto(researched as LCZ696, Novartis) which simultaneously blocks RAAS and NP. This dual action of angiotensin receptors blocker and neprilysin inhibitor(NPi) has improved HF prognosis and it is an evolution in the management of HF. Although the initial follow-up of patients treated with SV has yielded promising results, there are concerns regarding potential side effects especially an increase in the risk of Alzheimer's disease(AD) and young onset of AD. NPi interferes with the breakdown and clearing of beta-amyloid peptides, the plaques seen in AD, raising concern for AD in SV patients. On the other hand, hypertension and cardiovascular diseases are established risk factors for AD which can be decreased by SV therapy. It is therefore essential that SV treated patients are followed up over an extended period of time to detect any adverse cognitive changes.Nirav Patel Jason Gluck 2017World Journal of Cardiology2017,9,7:2
