BACKGROUND: The value of echocardiography in assessing disease severity and predicting outcome in pediatric pulmonary arterial hypertension (PAH) is insufficiently defined. The aim of this study was to describe correlations between echocardiography and disease severity and outcome in pediatric PAH.METHODS AND RESULTS: Forty-three consecutive children (median age, 8.0 years; range, 0.4-21.5) with idiopathic/hereditary PAH (n=25) or PAH associated with congenital heart disease (n=18) were enrolled in a prospective single-center observational study. Anatomic and right ventricular-functional variables were obtained by two-dimensional echocardiography and Doppler-echocardiography at presentation and at standardized follow-up and were correlated with measures of disease severity (World Health Organization functional class [WHO-FC], N-terminal-pro-B-type natriuretic peptide, hemodynamics) and lung-transplantation-free survival. Right atrial and right ventricular dimensions correlated with WHO-FC and hemodynamics (P<0.05), whereas left ventricular dimensions correlated with hemodynamics and survival (P<0.05). Right-to-left ventricular dimension ratiocorrelated with WHO-FC, hemodynamics and survival (P<0.05). Right ventricular ejection time correlated with hemodynamics and survival (P<0.05) and tended to correlate with WHO-FC (P=0.071). Tricuspid annular plane systolic excursion correlated with WHO-FC, mean right atrial pressure and survival (P<0.05).CONCLUSIONS: This early descriptive study shows that echocardiographic chararacteristics of both the right and the left heart correlate with disease severity and outcome in pediatric PAH, both at presentation and during the course of the disease. The preliminary data from this study support the potential value of echocardiography as a tool in guiding management in children with PAH. © 2014 American Heart Association, Inc.

OBJECTIVE—: Atherosclerosis, an inflammatory disease of arterial vessel walls, requires migration and matrix metalloproteinase (MMP)-9–dependent invasion of monocytes/macrophages into the vascular wall. MMP-9 expression is stimulated by transcription factor nuclear factor-κB, which is regulated by inhibitor κB and thus inhibitor κB-kinase IκB kinase. Regulators of nuclear factor-κB include serum- and glucocorticoid-inducible kinase 1 (SGK1). The present study explored involvement of SGK1 in vascular inflammation and atherogenesis.APPROACH AND RESULTS—: Gene-targeted apolipoprotein E (ApoE)–deficient mice without (apoesgk1) or with (apoesgk1) additional SGK1 knockout received 16-week cholesterol-rich diet. According to immunohistochemistry atherosclerotic lesions in aorta and carotid artery, vascular CD45 leukocyte infiltration, Mac-3 macrophage infiltration, vascular smooth muscle cell content, MMP-2, and MMP-9 positive areas in atherosclerotic tissue were significantly less in apoesgk1mice than in apoesgk1mice. As determined by Boyden chamber, thioglycollate-induced peritonitis and air pouch model, migration of SGK1-deficient CD11bF4/80 macrophages was significantly diminished in vitro and in vivo. Zymographic MMP-2 and MMP-9 production, MMP-9 activity and invasion through matrigel in vitro were significantly less in sgk1 than in sgk1macrophages and in control plasmid–transfected or inactive SGK1-transfected than in constitutively active SGK1-transfected THP-1 cells. Confocal microscopy revealed reduced macrophage number and macrophage MMP-9 content in plaques of apoesgk1 mice. In THP-1 cells, MMP-inhibitor GM6001 (25 μmol/L) abrogated SGK1-induced MMP-9 production and invasion. According to reverse transcription polymerase chain reaction, MMP-9 transcript levels were significantly reduced in sgk1macrophages and strongly upregulated in SGK1-transfected THP-1 cells compared with control plasmid–transfected or SGK1-transfected THP-1 cells. According to immunoblotting and confocal microscopy, phosphorylation of IκB kinase and inhibitor κB and nuclear translocation of p50 were significantly lower in sgk1macrophages than in sgk1macrophages and significantly higher in SGK1-transfected THP-1 cells than in control plasmid–transfected or SGK1-transfected THP-1 cells. Treatment of SGK1-transfected THP-1 cells with IκB kinase-inhibitor BMS-345541 (10 μmol/L) abolished SGK1-induced increase of MMP-9 transcription and gelatinase activity.CONCLUSIONS—: SGK1 plays a pivotal role in vascular inflammation during atherogenesis. SGK1 participates in the regulation of monocyte/macrophage migration and MMP-9 transcription via regulation of nuclear factor-κB. © 2015 American Heart Association, Inc.

OBJECTIVE—: Marfan’s syndrome is characterized by the formation of ascending aortic aneurysms resulting from altered assembly of extracellular matrix microfibrils and chronic tissue growth factor (TGF)-β signaling. TGF-β is a potent regulator of the vascular smooth muscle cell (VSMC) phenotype. We hypothesized that as a result of the chronic TGF-β signaling, VSMC would alter their basal differentiation phenotype, which could facilitate the formation of aneurysms. This study explores whether Marfan’s syndrome entails phenotypic alterations of VSMC and possible mechanisms at the subcellular level.APPROACH AND RESULTS—: Immunohistochemical and Western blotting analyses of dilated aortas from Marfan patients showed overexpression of contractile protein markers (α-smooth muscle actin, smoothelin, smooth muscle protein 22 alpha, and calponin-1) and collagen I in comparison with healthy aortas. VSMC explanted from Marfan aortic aneurysms showed increased in vitro expression of these phenotypic markers and also of myocardin, a transcription factor essential for VSMC-specific differentiation. These alterations were generally reduced after pharmacological inhibition of the TGF-β pathway. Marfan VSMC in culture showed more robust actin stress fibers and enhanced RhoA-GTP levels, which was accompanied by increased focal adhesion components and higher nuclear localization of myosin-related transcription factor A. Marfan VSMC and extracellular matrix measured by atomic force microscopy were both stiffer than their respective controls.CONCLUSIONS—: In Marfan VSMC, both in tissue and in culture, there are variable TGF-β-dependent phenotypic changes affecting contractile proteins and collagen I, leading to greater cellular and extracellular matrix stiffness. Altogether, these alterations may contribute to the known aortic rigidity that precedes or accompanies Marfan’s syndrome aneurysm formation. © 2015 American Heart Association, Inc.

Tetrahedron Asymmetry | Year: 2011
Non-proteinogenic prolines have been acknowledged as an important pool for the synthesis of conformationally rigid bioactive peptides, angiotensin converting enzyme inhibitors and as pharmacological probes. Proline and its derivatives are often used as asymmetric catalysts in organic reactions, such as CBS reductions and proline catalyzed aldol reactions, Mannich reactions, and so on. Furthermore l-proline is an osmoprotectant and is therefore frequently used in many pharmacological as well as biotechnological applications. The wide range of chemical and biological applications associated with l-proline has prompted researchers to develop new methodologies for the synthesis of prolines and substituted prolines and to further explore their chemical and biological applications. The present article is an attempt to discuss all the major advances available till date, describing the use of proline in organic asymmetric synthesis, the synthesis of various bioactive molecules or proline as a constituent part of bioactive molecules. © 2011 Elsevier Ltd.

Thirty percent to 90% of cancer survivors report impaired sleep quality post-treatment, which can be severe enough to increase morbidity and mortality. Lifestyle interventions, such as exercise, are recommended in conjunction with drugs and cognitive behavioral therapy for the treatment of impaired sleep. Preliminary evidence indicates that yoga-a mind-body practice and form of exercise-may improve sleep among cancer survivors. The primary aim of this randomized, controlled clinical trial was to determine the efficacy of a standardized yoga intervention compared with standard care for improving global sleep quality (primary outcome) among post-treatment cancer survivors. In all, 410 survivors suffering from moderate or greater sleep disruption between 2 and 24 months after surgery, chemotherapy, and/or radiation therapy were randomly assigned to standard care or standard care plus the 4-week yoga intervention. The yoga intervention used the Yoga for Cancer Survivors (YOCAS) program consisting of pranayama (breathing exercises), 16 Gentle Hatha and Restorative yoga asanas (postures), and meditation. Participants attended two 75-minute sessions per week. Sleep quality was assessed by using the Pittsburgh Sleep Quality Index and actigraphy pre- and postintervention. In all, 410 survivors were accrued (96% female; mean age, 54 years; 75% had breast cancer). Yoga participants demonstrated greater improvements in global sleep quality and, secondarily, subjective sleep quality, daytime dysfunction, wake after sleep onset, sleep efficiency, and medication use at postintervention (all P ≤ .05) compared with standard care participants. Yoga, specifically the YOCAS program, is a useful treatment for improving sleep quality and reducing sleep medication use among cancer survivors.

BACKGROUND: Higher levels of physical activity are associated with reduced cardiovascular mortality but its effect on age-related changes in cardiac structure and function is unknown. The present study defines the effect of daily physical activity on age-related changes in cardiac structure, function, metabolism, and performance in healthy women.METHODS AND RESULTS: Sixty-three healthy women were grouped according to age (young, 20-30 years, n=21; middle, 40-50 years, n=22; and older, 65-81 years, n=20) and daily physical activity level (low active<7500 and high active>12,500 steps/d). Participants underwent cardiac MRI including tissue tagging and 31P spectroscopy and exercise testing with noninvasive central hemodynamic measurements. Aging was associated with increased concentric remodeling (P<0.01) and left ventricular torsion (P<0.01), and a decline in diastolic function (P<0.01), cardiac phosphocreatine:ATP ratio (P<0.01), peak exercise cardiac power output (P<0.01), and O2 consumption (P<0.01). Older high-active women demonstrated a phosphocreatine:ATP ratio and relative peak O2 consumption similar to young low-active women, and 23% and 26% higher than older low-active women (phosphocreatine:ATP ratio, 1.9±0.2 versus 1.4±0.1; P<0.05 and O2 consumption, 24.1±3.8 versus 17.8±2.0 mL/[kg·min]; P<0.01). In older women, physical activity had no effect on eccentricity ratio (0.9±0.2 versus 0.8±0.1 g/mL; P=0.19), E/A ratio (1.3±0.5 versus 1.4±0.5; P=0.66), torsion (7.6±1.7 versus 8.0°±2.1°; P=0.20), and peak cardiac power output (3.4±0.7 versus 3.4±0.8 W; P=0.91).CONCLUSIONS: A higher level of daily physical activity preserves cardiac metabolism and exercise capacity with aging but has limited effect on age-related changes in concentric remodeling, diastolic function, and cardiac performance. © 2014 American Heart Association, Inc.

Copeptin, a surrogate biomarker of vasopressin, has been associated with renal function decline and may serve as a useful early biomarker for preeclampsia. We measured serum copeptin using samples collected longitudinally during pregnancy among unaffected controls (n=136) and cases of preeclampsia (n=169), gestational diabetes mellitus (n=92), gestational hypertension (n=101), and preterm birth (n=86) in the Calcium for Preeclampsia Prevention trial (1992–1995). Preeclampsia and gestational hypertension were defined as having a diastolic blood pressure ≥90 mm Hg on 2 occasions with and without proteinuria, respectively. The risk of pregnancy complications associated with copeptin was estimated by logistic regression adjusting for maternal age, race, body mass index, insurance status, marital status, current smoking, and clinical site. Baseline copeptin levels, at mean 16 weeks of gestation, were associated with increased preeclampsia risk (adjusted odds ratios and 95% confidence interval being 1.55 per log unit; 1.03–2.31) when compared with controls (P=0.03). The association was stronger among cases diagnosed before 37 weeks (1.86; 1.08–3.20) than those diagnosed later (1.45; 0.91–2.32). Copeptin levels rose with increasing gestational age in both cases and controls but remained significantly higher among those who were diagnosed with preeclampsia. Differences in levels of copeptin between cases and controls became more apparent closer to time of diagnosis. No significant associations were found for gestational hypertension without proteinuria, gestational diabetes mellitus, or preterm birth without preeclampsia. Copeptin levels are elevated in pregnant women before diagnosis of preeclampsia with elevation specific to this pregnancy complication rather than hypertension alone. © 2014 American Heart Association, Inc

Whether changes over time of urinary albumin excretion have prognostic value is a matter of discussion. The objective was to assess the prognostic value of changes in urinary albumin excretion over time in cardiovascular risk during antihypertensive treatment. Follow-up study of 2835 hypertensives in the absence of previous cardiovascular disease (mean age 55 years, 47% men, BP 138/80 mm Hg, 19.1% diabetics, and calibrated systemic coronary risk estimation 5 or >10.6%). Usual-care of antihypertensive treatment was implemented to maintain blood pressure <140/90 mm Hg. Urinary albumin excretion was assessed yearly, and the values were expressed as the creatinine ratio. Incidence of cardiovascular events, fatal and nonfatal, was recorded during the follow-up. During a median follow-up of 4.7 years (17 028 patients-year), 294 fatal and first nonfatal cardiovascular events were recorded (1.73 CVD per 100 patients/year). Independently of blood pressure, estimated glomerular filtration rate, level of cardiovascular risk, and antihypertensive treatment, microalbuminuria at baseline and at any time during the follow-up resulted in higher risk for events, hazard ratio (HR) 1.35 (95% confidence interval [CI], 1.08–1.79) and HR 1.49 (95% CI, 1.14–1.94), respectively. Likewise, development of microalbuminuria (HR 1.60; 95% CI, 1.04–2.46) or persistence from the beginning (1.53; 95% CI, 1.13–2.06) had a significantly higher rate of events than if remained normoalbuminuric (HR 1) or regress to normoalbuminuria (HR 1.37; 95% CI, 0.92–2.06) with an 18%, 18%, 8%, and 11% events, respectively, P<0.001. The study supports the value of urinary albumin excretion assessment as a prognostic factor for cardiovascular risk, but also opens the way to consider it as an intermediate objective in hypertension. © 2014 American Heart Association, Inc

BACKGROUND—: Out-of-hospital cardiac arrest (OHCA) is associated with a poor prognosis and poses a significant burden to the healthcare system, but few studies have evaluated whether OHCA incidence and survival have changed over time.METHODS AND RESULTS—: A population-based cohort study was conducted, including 34 291 OHCA patients >20 years ofage who were transported alive to the emergency department of an acute-care hospital from April 1, 2002, to March 31, 2012, in Ontario, Canada. Patients with life-threatening trauma and those who died before hospital arrival were excluded. The overall age- and sex-standardized incidence of OHCA patients who were transported alive was 36 cases per 100 000 persons and did not significantly change over the study period. Cardiac risk factor prevalence increased significantly, whereas the rate of most cardiovascular conditions decreased significantly. The 30-day survival improved from 9.4% in 2002 to 13.6% in 2011; 1-year survival improved from 7.7% to 11.8% (P<0.001). Patients hospitalized in 2011 were significantly more likely to survive 30 days (adjusted odds ratio, 1.47 [95% CI, 1.22–1.77]) and 1 year (adjusted odds ratio, 1.55 [95% CI, 1.27–1.91]) compared with 2002. A significant interaction between temporal trends in survival improvement and age group was observed in which the improvement in survival was largest in the youngest age groups.CONCLUSIONS—: OHCA patients who were transported alive are increasingly likely to have cardiovascular risk factors but less likely to have previous cardiovascular conditions. The overall incidence of OHCA patients transported to hospital alive did not change over the past decade. Short- and longer-term survival after OHCA has substantially improved, with younger patients experiencing the greatest improvement. © 2014 by the American College of Cardiology Foundation and the American Heart Association, Inc.

We examined trends in the treatment of femoral neck fractures over the last two decades. We used Medicare Part A administrative data to identify patients hospitalized for closed femoral neck fracture from 1991 to 2008. We used codes from the International Classification of Diseases, Ninth Revision, to categorize treatment as nonoperative, internal fixation, hemiarthroplasty, and total hip arthroplasty. We examined differences in treatment according to hospital hip fracture volume, hospital location (rural or urban), and teaching status. Our sample consisted of 1,119,423 patients with intracapsular hip fractures occurring from 1991 to 2008. We found a generally stable trend over time in the percentage of patients managed with nonoperative treatment, internal fixation, hemiarthroplasty, and total hip arthroplasty. We found little difference in surgical treatment across different groups of hospitals (high volume compared with low volume, urban compared with rural, and teaching compared with nonteaching). The percentage of acute care hospitals treating hip fractures remained fairly constant (74.8% in 1991 to 1993 and 69.0% in 2006 to 2008). The median number of hip fractures treated per hospital did not change (thirty-three in 1991 to 1993 and thirty-three in 2006 to 2008). There was no increase in the percentage of fractures treated in high-volume hospitals over time (57.7% in 1991 to 1993 and 57.1% in 2006 to 2008) and little reduction in the percentage of fractures treated in low-volume hospitals (5.8% in 1991 to 1993 and 5.5% in 2006 to 2008). There has been little change in the trends of operative and nonoperative treatment for proximal femoral fractures over the last two decades, and there was little evidence of regionalization of hip fracture treatment to higher-volume hospitals.
