The aim of the present study was to evaluate the association between primary anesthesia type and postprocedural complications for endovascular angioplasty of aortoiliac occlusion. DESIGN Retrospective cohort study. SETTING Multi-institutional. PARTICIPANTS The study comprised 3,110 patients undergoing endovascular angioplasty of aortoiliac occlusive disease, with 1,974 and 1,136 patients who underwent monitored anesthesia care (MAC) and general anesthesia (GA), respectively. The American College of Surgeons National Surgical Quality Improvement Program database for the years 2012 to 2016 was used for the present study. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The final analysis included 3,110 patients, 63% of whom received MAC and 37% of whom received GA. The mean age was 64 years among the GA group, of whom 57.2% were male. The mean age among that MAC group was 65 years, 55.8% of whom were male. After adjusting for demographic factors and preoperative comorbidities, there was a statistically significant lower odds of postoperative complications (ie, pulmonary complications, infection, intraoperative/postoperative transfusion, reoperation, and amputation) and shorter length of stay in the MAC group compared with the GA group (p less then 0.05). CONCLUSIONS Although larger observational studies and randomized controlled trials are needed to further evaluate the potential effect of MAC versus GA, MAC anesthesia should be considered for patients undergoing endovascular angioplasty for aortoiliac occlusion. Redox reactions control fundamental processes of human biology. Therefore, it is safe to assume that the responses and adaptations to exercise are, at least in part, mediated by redox reactions. In this review, we are trying to show that redox reactions are the basis of exercise physiology by outlining the redox signaling pathways that regulate four characteristic acute exercise-induced responses (muscle contractile function, glucose uptake, blood flow and bioenergetics) and four chronic exercise-induced adaptations (mitochondrial biogenesis, muscle hypertrophy, angiogenesis and redox homeostasis). Based on our analysis, we argue that redox regulation should be acknowledged as central to exercise physiology. V.BACKGROUND Duchenne muscular dystrophy (DMD) is caused by the loss of dystrophin. Severe and ultimately lethal, DMD progresses relatively slowly in that patients become wheelchair bound only around age twelve with a survival expectancy reaching the third decade of life. METHODS The mildly-affected mdx mouse model of DMD, and transgenic DysΔMTB-mdx and Fiona-mdx mice expressing dystrophin or utrophin, respectively, were exposed to either mild (scruffing) or severe (subordination stress) stress paradigms and profiled for their behavioral and physiological responses. A subgroup of mdx mice exposed to subordination stress were pretreated with the beta-blocker metoprolol. FINDINGS Subordination stress caused lethality in ∼30% of mdx mice within 24 h and ∼70% lethality within 48 h, which was not rescued by metoprolol. Lethality was associated with heart damage, waddling gait and hypo-locomotion, as well as marked up-regulation of the hypothalamus-pituitary-adrenocortical axis. A novel cardiovascular phenotype emerged in mdx mice, in that scruffing caused a transient drop in arterial pressure, while subordination stress caused severe and sustained hypotension with concurrent tachycardia. Transgenic expression of dystrophin or utrophin in skeletal muscle protected mdx mice from scruffing and social stress-induced responses including mortality. INTERPRETATION We have identified a robust new stress phenotype in the otherwise mildly affected mdx mouse that suggests relatively benign handling may impact the outcome of behavioural experiments, but which should also expedite the knowledge-based therapy development for DMD.

AIMS Chronic total occlusion (CTO) has been linked to worse survival. While controversial and limited to observational data, successful CTO percutaneous coronary intervention (PCI) has been associated with improved left ventricular (LV) function and mortality. However, the role of CTO PCI prior to transcatheter aortic valve replacement (TAVR) is not clear. We sought to explore the prognostic impact of a pre-TAVR CTO on post-TAVR outcomes. METHODS AND RESULTS We retrospectively reviewed 783 consecutive TAVR cases performed at a single tertiary care medical center. Pre-TAVR angiograms were analyzed for the presence of a CTO. At the time of TAVR, 12.6% (n = 99) patients had a CTO. At one-year post-TAVR, there was no significant association between the presence of a CTO and death (14.2% vs 13.1%, p = 0.75), functional status, quality of life, or adverse events. There was also no difference in long-term survival (4.1 years vs 4.1 years, p = 0.55). LV ejection fraction was lower in the CTO group at baseline and one year (p  less then  0.01). CONCLUSIONS The presence of a CTO did not have any prognostic impact on mortality, change in LV function, or improvement in functional status and angina scores following TAVR in our cohort of elderly, high-risk patients. CTO before TAVR was associated with decreased ejection fraction at baseline and at one year. We observed a calcified nodule (CN) protruding into the coronary lumen through the stent struts of an in-stent restenosis (ISR) lesion in detail using optical coherent tomography (OCT). The patient was a 56-year-old Japanese male on regular hemodialysis for his end-stage renal disease who had multiple coronary risk factors. He previously underwent percutaneous coronary intervention (PCI) for the middle left anterior descending artery and a drug-eluting stent was implanted. OCT showed a CN in the culprit lesion. He underwent coronary angiography 9 months later, and an ISR lesion was observed. Re-PCI was done, and a drug-coated balloon was used. OCT showed a CN protruding into the coronary lumen through the stent struts in the ISR lesion. Although this phenomenon was previously reported in a pathological study, the observation of a CN protruding through stent struts by in-vivo OCT has been rarely demonstrated previously. The present study provides support for the previous pathological report, and demonstrates a useful application of OCT imaging that can help in the treatment of ISR lesions. PROBLEM AND AIM Women's childbirth experience is central when assessing intrapartum care quality. This study accordingly measures women's childbirth experience in Rwandan health facilities, focusing on own capacity and perceived safety. METHODS A cross-sectional health facility-based study was conducted December 2014 to January 2015 in Kigali City and the Northern Province. selleck chemicals llc Childbirth experience was assessed before discharge using an overall assessment and two subscales, Own capacity and Perceived safety, of the Childbirth Experience Questionnaire, with high scores reflecting a good experience. The questionnaire was translated from English into Kinyarwanda. Reliability was tested using Cronbach's alpha; and mean scores between groups were compared using Mann-Whitney U test. FINDINGS All invited women (n = 817) agreed to participate after informed consent. Mean age was 27.8 years and 63.6% were multiparous. A majority of women (82.3%) reported an overall positive childbirth experience (≥8 out of 10). Cronbach's alpha indicated good reliability for Own capacity (0.78) and Perceived safety (0.76). In both subscales multiparous women had higher mean scores than primiparous, married women scored higher than unmarried, older women (>35) scored higher than younger ( less then 35), and women with higher level of education scored higher than those with lower level. Women with HIV scored lower on perceived safety. CONCLUSION A majority of the women reported a positive overall childbirth experience. Own capacity and perceived safety are important dimensions of childbirth experience and should be addressed in building high-quality intrapartum care. Further research is needed and should include exploration of specific groups. Pericyte, a kind of pluripotent cell, may regulate the irrigation flow and permeability of microcirculation. Pericytes are similar to the smooth muscle cells, which express several kinds of contractile proteins and have contractility. The dysfunction of pericytes is related to many microvascular diseases, including hypoxia, hypertension, diabetic retinopathy, fibrosis, inflammation, Alzheimer's disease, multiple sclerosis, and tumor formation. For a long time, their existence and function have been neglected. The distribution, structure, biomarker, related signaling pathways as well as the roles of pericytes on vascular diseases will be introduced in this review. BACKGROUND/OBJECTIVE Volume replacement with the latissimus dorsi (LD) is an option for patients after partial mastectomy. Although potential benefits of using the endoscopic technique have been previously described, previous studies have not assessed long term volume and aesthetic outcomes compared to traditional methods. In this study, we aim to compare the endoscopic, latissimus only harvest to the traditional latissimus with skin paddle method. METHODS Eleven patients underwent breast reconstruction with the traditional LD flap harvesting method; 9 underwent endoscopically assisted LD flap reconstruction. The difference between preoperative and >1 year postoperative volumes were recorded. Patient satisfaction and surgeon-based observer assessment of the breast aesthetic and donor site scar were compared between the two techniques. RESULTS Compared to the traditional group, there was a significant mean volume reduction in the endoscopic group (70.3 vs 21.7 cc, p = 0.0023). Operative time was also longer in the endoscopic group than in the traditional group (368 vs 257 min, p  less then  0.001). In observer assessment criteria, the result of the donor site scar assessment was superior in the endoscopic group in terms of vascularity (p = 0.0038), relief (p = 0.0023), and pliability (p = 0.053). CONCLUSION Patients' attitudes and feelings about the scar were better in the endoscopic group than in the traditional group. However, compared to the endoscopic group, the traditional group achieved a better breast cosmetic result and better retention of volume postoperatively, possibly due to incorporation of the skin flap and adipo-fascial tissue.
