Prenatal HI also increased the vasoconstrictor response to norepinephrine, the media thickness, collagen deposition, and the oxidative damage in the aorta from adult male offspring compared to control and sham groups. Our results suggest an association among prenatal HI and adult vascular structural and functional changes, oxidative stress damage, and depressive behavior.

A cluster of aortic bioprosthetic valve failures, most of which were Trifecta bioprostheses, was observed in our institution. This study was performed to assess if the cluster represents a significant failure of this valve model or if there is a selection bias that can explain the failure of these valves.

This retrospective study evaluated all bioprosthetic aortic valve replacement operations performed between 2011-2016 inclusive in our center. We compared the performance of Trifecta with that of Perimount, Perimount Magna Ease and Mitroflow bioprostheses. In addition, we analyzed patient-related and valve-related risk factors for early failure in the failed valves.

A total of 2807 bioprosthetic aortic valve replacements were performed. Of these, 836 were Trifecta valves, 1031 Perimount, 449 Perimount Magna Ease and 351 Mitroflow valves. Twenty-four Trifecta valves suffered premature structural failure significantly higher than Perimount or Perimount Magna Ease (no failure, p<0.0001 and p<0.005 respectively) and Mitroflow (one failure, p<0.05). There was no difference in the incidence of endocarditis or death At the time of failure, 17(71%) of the failed Trifecta valves had moderate or severe regurgitation and the average peak gradient was 61±29mmHg. The median failed prosthetic size was 23mm. One failed valve had severe patient-prosthesis mismatch. The mean time to failure was 4.5±1.7 years..

The Trifecta bioprosthesis has an increased incidence of early structural valve failure, which is significantly higher than that of Perimount, Perimount Magna Ease or Mitroflow. No patient-related or valve-related cause for the failure could be identified.

The incidence and financial impact of persistent opioid use (POU) after open aortic surgery is undefined.

Insurance claim data from opioid-naïve patients who underwent aortic root replacement, ascending aortic replacement or transverse arch replacement from 2011 to 2017 were evaluated. Persistent opioid use was defined as filling an opioid prescription in the perioperative period and between 90 and 180 days after surgery. Postoperative opioid prescriptions, emergency room visits, readmissions and healthcare costs were quantified. Multivariable logistic regression identified risk factors for POU, and quantile regression quantified the impact of POU on postoperative healthcare costs.

Among 3,240 opioid-naïve patients undergoing open aortic surgery, 169 (5.2%) of patients had POU. In the univariate analysis, patients with POU were prescribed more perioperative opioids (375 vs. 225 morphine milligram equivalents, p<0.001), had more emergency room visits (45.6% vs. 25.4%, p<0.001) and had significantly higher healthcare payments in the 6 months after surgery ($10,947 vs. $7,223, p<0.001). Independent risk factors for POU in the multivariable logistic regression included preoperative nicotine use and more opioids in the first perioperative prescription (all p<0.05). After risk adjustment, POU was associated with a $2,439 increase in total healthcare costs in the 6 months after surgery.

POU is a challenge after open aortic surgery and can have longer term impacts on healthcare payments and emergency room visits in the 6 months after surgery. Strategies to reduce outpatient opioid use after aortic surgery should be encouraged when feasible.

The current study was conducted to investigate the antitumor activity of the outer membrane vesicles (ST-OMVs) of Salmonella Typhimurium ATCC 14028, in vitro in human colorectal carcinoma (HTC116), breast cancer (MCF-7), and hepatocellular carcinoma (HepG2) cell lines and in vivo in Ehrlich solid carcinoma-bearing mice model either as a mono-immunotherapy or as an adjuvant to a commonly used conventional chemotherapy. In addition, we investigated the safety of ST-OMVs. Adult Swiss albino female mice with transplanted Ehrlich solid carcinoma were treated with either ST-OMVs, paclitaxel or a combination of both. Tumor volume, growth inhibition rate, quantitative RT-PCR of Bax and VEGF genes expression, histopathology and immune-expression of caspase-3, Beclin-1, CD49b and Ki-67 were all analyzed. Our results showed that ST-OMVs significantly decreased tumor volume, significantly increased tumor growth inhibition rate, up-regulated the immunohistochemical expression of caspase-3, Beclin-1, and CD49b (enhanced recruitment of NK cells). Furthermore, ST-OMVs down-regulated the expression of Ki-67, increased Bax gene expression and decreased VEGF gene expression as detected by qRT-PCR analysis. Histologically, ST-OMVs promoted apoptosis, decreased tumor invasion and mitotic activities. Moreover, ST-OMVs showed a remarkable cytotoxic activity in various investigated in vitro cancer cell lines. Our findings demonstrate potential antitumor activity of ST-OMVs that might be used as a promising safe antitumor immunotherapy or an adjuvant to conventional chemotherapeutic drugs, resolving some of their problems.

Epithelial ovarian cancer (EOC) is a highly fatal gynecological cancer. A long noncoding RNA (lncRNA) gastric cancer-associated lncRNA1 (GClnc1) has been revealed to play critical roles in metastasis. Therefore, the present study aims to explore the correlation between GClnc1 and the metastasis and progression of EOC.

First, 57 paired EOC and paracancerous tissues were collected to detect GClnc1 expression by RT-qPCR. Subsequently, OVC1 and SKOV3 cells with GClnc1 silencing/overexpression were developed to detect changes in cell activity, apoptosis, migration and invasion abilities. TRAM-34 ic50 Then, the subcellular localization of GClnc1 was detected by nuclear/cytoplasmic fractionation, ISH and FISH assays. The binding relationships between GClnc1 and forkhead box protein C2 (FOXC2), and between FOXC2 and NOTCH1 were predicted and verified.

GClnc1 was significantly overexpressed in EOC tissues, and knockdown of GClnc1 inhibited cell viability and promoted apoptosis. Moreover, GClnc1 in the nucleus bound to the transcription factor FOXC2, thereby activating the transcription of NOTCH1.
