Abstract
Importance Although early trials of endovascular renal denervation (RDN) for patients with resistant hypertension (RHTN) reported inconsistent results, ultrasound RDN (uRDN) was found to decrease blood pressure (BP) vs sham at 2 months in patients with RHTN taking stable background medications in the Study of the ReCor Medical Paradise System in Clinical Hypertension (RADIANCE-HTN TRIO) trial. Objectives To report the prespecified analysis of the persistence of the BP effects and safety of uRDN vs sham at 6 months in conjunction with escalating antihypertensive medications. Design, Setting, and Participants This randomized, sham-controlled, clinical trial with outcome assessors and patients blinded to treatment assignment, enrolled patients from March 11, 2016, to March 13, 2020. This was an international, multicenter study conducted in the US and Europe. Participants with daytime ambulatory BP of 135/85 mm Hg or higher after 4 weeks of single-pill triple-combination treatment (angiotensin-receptor blocker, calcium channel blocker, and thiazide diuretic) with estimated glomerular filtration rate (eGFR) of 40 mL/min/1.73 m2 or greater were randomly assigned to uRDN or sham with medications unchanged through 2 months. From 2 to 5 months, if monthly home BP was 135/85 mm Hg or higher, standardized stepped-care antihypertensive treatment starting with aldosterone antagonists was initiated under blinding to treatment assignment. Interventions uRDN vs sham procedure in conjunction with added medications to target BP control. Main Outcomes and Measures Six-month change in medications, change in daytime ambulatory systolic BP, change in home systolic BP adjusted for baseline BP and medications, and safety. Results A total of 65 of 69 participants in the uRDN group and 64 of 67 participants in the sham group (mean [SD] age, 52.4 [8.3] years; 104 male [80.6%]) with a mean (SD) eGFR of 81.5 (22.8) mL/min/1.73 m2 had 6-month daytime ambulatory BP measurements. Fewer medications were added in the uRDN group (mean [SD], 0.7 [1.0] medications) vs sham (mean [SD], 1.1 [1.1] medications; P = .045) and fewer patients in the uRDN group received aldosterone antagonists at 6 months (26 of 65 [40.0%] vs 39 of 64 [60.9%]; P = .02). Despite less intensive standardized stepped-care antihypertensive treatment, mean (SD) daytime ambulatory BP at 6 months was 138.3 (15.1) mm Hg with uRDN vs 139.0 (14.3) mm Hg with sham (additional decreases of -2.4 [16.6] vs -7.0 [16.7] mm Hg from month 2, respectively), whereas home SBP was lowered to a greater extent with uRDN by 4.3 mm Hg (95% CI, 0.5-8.1 mm Hg; P = .03) in a mixed model adjusting for baseline and number of medications. Adverse events were infrequent and similar between groups. Conclusions and Relevance In this study, in patients with RHTN initially randomly assigned to uRDN or a sham procedure and who had persistent elevation of BP at 2 months after the procedure, standardized stepped-care antihypertensive treatment escalation resulted in similar BP reduction in both groups at 6 months, with fewer additional medications required in the uRDN group.

Abstract
Abstract
A collaborative study was conducted for the determination of vitamins A and E. Existing AOAC liquid chromatographic (LC) methods are suited for specific vitamins A and E analytical applications. This method differs from existing methods in that it can be used to assay samples in all 9 sectors of the food matrix. Standards and test samples are saponified in basic ethanol–water solution, neutralized, and diluted, converting fats to fatty acids and retinol esters and tocopherol esters to retinol and tocopherol, respectively. Retinol and alpha-tocopherol are quantitated on separate LC systems, using UV detection at 313 or 328 nm for retinol, and fluorescence detection (excitation 290 nm, emission 330 nm) for alpha-tocopherol. Vitamin concentrations are calculated by comparison of the peak heights or peak areas of vitamins in test samples with those of standards.

Abstract
Abstract
Background
In non-obstructive coronary artery disease (CAD), increasing extent of disease is associated with a worse prognosis. Statin therapy has been suggested to improve the prognosis. Whether hypertension, a modifiable CV risk factor, affects the extent of non-obstructive CAD in patients with stable angina is less explored.
Purpose
To assess the association between hypertension and extent of non-obstructive coronary artery disease.
Methods
We identified 1117 patients (mean age 62±10 years, 48% women) from the Norwegian Registry for Invasive Coronary angiography (NORIC). All subjects had stable angina and non-obstructive CAD defined as 1–49% stenosis in any coronary artery segment by coronary computed tomography angiography (CCTA). The extent of non-obstructive CAD was assessed as coronary artery segment involvement score (SIS) on CCTA. Extensive non-obstructive CAD was defined as SIS≥4.
Results
Hypertension was present in 44% and patients with hypertension were older with a higher prevalence of diabetes, obesity, smoking and statin therapy (all p<0.05). Coronary artery SIS and calcium score were higher in patients with hypertension compared to those without hypertension, (3.1±2.0 vs. 2.6±1.7, p<0.001 and 41 (116) vs. 32 (91) HU, p<0.05), respectively. There was no significant sex difference in the prevalence of hypertension. In univariable analysis, hypertension, age, calcium score and statin treatment were significantly associated with extensive non-obstructive CAD (Table). Hypertension remained a strong, independent predictor of extensive non-obstructive CAD after adjusting for other known covariables (Table).
Table 1. Covariables of extensive non-obstructive CAD in univariable and multivariable logistic regression analysis Univariable analysis Multivariable analysis OR 95% CI p-value OR 95% CI p-value Hypertension 1.57 1.21–2.04 0.001 1.47 1.03–2.10 0.035 Age 1.06 1.05–1.08 <0.001 1.04 1.01–1.06 0.001 Calcium score 1.02 1.01–1.02 <0.001 1.01 1.01–1.02 <0.001 Statin treatment 1.34 1.03–1.75 0.029 1.20 0.83–1.70 0.341 Smoking 1.33 1.00–1.77 0.052 1.24 0.86–1.78 0.251 Diabetes mellitus 1.34 0.86–2.12 0.191 1.10 0.57–2.09 0.781 Obesity 1.03 0.76–1.41 0.839 1.19 0.79–1.80 0.425
Conclusions
Hypertension is associated with extensive non-obstructive CAD in patients with stable angina, suggesting that early and aggressive antihypertensive treatment may impact disease progression.

Abstract
BACKGROUND The multicenter, international, randomized, blinded, sham-controlled RADIANCE-HTN SOLO trial (A Study of the ReCor Medical Paradise System in Clinical Hypertension) demonstrated a 6.3 mm Hg greater reduction in daytime ambulatory systolic blood pressure (BP) at 2 months by endovascular ultrasound renal denervation (RDN) compared with a sham procedure among patients not treated with antihypertensive medications. We report 6-month results after the addition of a recommended standardized stepped-care antihypertensive treatment to the randomized endovascular procedure under continued blinding to initial treatment. METHODS Patients with a daytime ambulatory BP ≥135/85 mm Hg and <170/105 mm Hg after a 4-week discontinuation of up to 2 antihypertensive medications, and a suitable renal artery anatomy, were randomized to RDN (n=74) or sham (n=72). Patients were to remain off antihypertensive medications throughout the first 2 months of follow-up unless safety BP criteria were exceeded. Between 2 and 5 months, if monthly measured home BP was ≥135/85 mm Hg, a standardized stepped-care antihypertensive treatment was recommended consisting of the sequential addition of amlodipine (5 mg/d), a standard dose of an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and hydrochlorothiazide (12.5 mg/d), followed by the sequential uptitration of hydrochlorothiazide (25 mg/d) and amlodipine (10 mg/d). Outcomes included the 6-month (1) change in daytime ambulatory systolic BP adjusted for medications and baseline systolic BP, (2) medication burden, and (3) safety. RESULTS A total of 69/74 RDN patients and 71/72 sham patients completed the 6-month ambulatory BP measurement. At 6 months, 65.2% of patients in the RDN group were treated with the standardized stepped-care antihypertensive treatment versus 84.5% in the sham group (P=0.008), and the average number of antihypertensive medications and defined daily dose were less in the RDN group than in the sham group (0.9±0.9 versus 1.3±0.9, P=0.010 and 1.4±1.5 versus 2.0±1.8, P=0.018; respectively). Despite less intensive standardized stepped-care antihypertensive treatment, RDN reduced daytime ambulatory systolic BP to a greater extent than sham (-18.1±12.2 versus -15.6±13.2 mm Hg, respectively; difference adjusted for baseline BP and number of medications: -4.3 mm Hg, 95% confidence interval, -7.9 to -0.6, P=0.024). There were no major adverse events in either group through 6 months. CONCLUSIONS The BP-lowering effect of endovascular ultrasound RDN was maintained at 6 months with less prescribed antihypertensive medications compared with a sham control.

Abstract
AIM Repair of ruptured abdominal aortic aneurysm (rAAA) is reported to have a higher mortality in women than in men. The aim was to study whether this difference could be verified in our institution and secondary if difference in risk- and complication profiles could explain the higher 30 day mortality after surgery for rAAA in women. METHODS During the period 1983-2009 1649 patients, 1348 men and 301 women, were operated consecutively for infrarenal abdominal aortic aneurysm (AAA); 430 patients had rAAA, 98 women and 332 men. Co-morbidities were identified from the patients' medical records. Outcome measures within 30 days were mortality, cardiac disease (heart attack, heart failure), cerebrovascular disease (stroke, TIA), renal insufficiency (serum creatinine >140 µmol/L), major amputation, bowel infarction, pancreatitis and graft related complications. RESULTS Compared to men, women had higher 30 d mortality after surgery for rAAA (54.1% vs. 36.3%, P=0.002). Women were significantly older than men (76 years vs. 73 years, P=0.001). In the period 1995-2009 women had more autoimmune diseases than men (P=0.045). There was no significant difference between men and women for the other measured outcomes. CONCLUSION During the period 1995-2009, autoimmune disease were more common among women than men. For all other parameters recorded, there were no differences in risk - or complication profile that could explain the higher 30 d mortality in female patients after surgery for rAAA.

Abstract
OBJECTIVES Free fatty acids (FFAs) are the major energy sources of the heart, and fatty acids (FAs) are active components of biological membranes. Data indicate that levels of FAs and their composition may influence myocardial function and inflammation. The aim of this study was to investigate whether total levels and composition of FAs and FFAs in plasma are altered in clinical heart failure (HF) and whether any alterations in these parameters are correlated with the severity of HF. SUBJECTS Plasma from 183 patients with stable HF was compared with plasma from 44 healthy control subjects. RESULTS Our main findings are as follows: (i) patients with HF had decreased levels of several lipid parameters and increased levels of FFAs in plasma, compared with controls, which were significantly correlated with clinical disease severity. (ii) Patients with HF also had a decreased proportion in the plasma of several n-3 polyunsaturated FAs, an increased proportion of several monounsaturated FAs, and a decreased proportion of some readily oxidized long-chain saturated FAs. (iii) These changes in FA composition were significantly associated with functional class, impaired cardiac function (i.e., decreased cardiac index and increased plasma N-terminal pro-B-type natriuretic peptide levels) and enhanced systemic inflammation (i.e., increased high-sensitivity C-reactive protein levels). (iv) Low levels of C20:4n-3 (eicosatetraenoic acid) and in particular high levels of C18:1n-7 (vaccenic acid) were significantly associated with total mortality in this HF population. CONCLUSIONS Our data demonstrate that patients with HF are characterized by a certain FA phenotype and may support a link between disturbed FA composition and the progression of HF.

Abstract
Heterochrony (evolutionary modifications in developmental timing and/or rates) is widely recognized as an important agent of morphological change. The adaptive significance of heterochronic changes might lie either in the advantages of the derived morphologies (organ size and shape) or the derived growth parameters themselves (rate and duration of growth). We have tested these hypotheses by comparing the growth rate, the duration of growth and the relative length of the adult tibia in Primates in a phylogenetic context. We report an evolutionary decrease in growth rates (paedochronocline) and an increase in the duration of growth (perachronocline), lying in the cline from the last common ancestor of Primates, passing through the last common ancestor of Haplorhini, that of Catarrhini, to the last common ancestor of the Hominidae. However, the variation in the relative length of the adult tibia does not show any phylogenetic pattern. The derived growth parameters in themselves (slower rate, longer duration) would be of adaptive significance and they would have been selected because a prolonged learning period prior to maturity conferred advantage. The proximate (developmental) causation of differences in bone growth rate were also investigated and it was found that cell production rate in the growth plates rather than the chondrocyte size, underlies the variation in bone growth rate.

Abstract
In March 1999, E. Daynes, a sculptor specializing in fossil hominid reconstruction, asked C. Berge to take over the scientific supervision of the reconstruction of two australopithecine post-crania. The heads had been modeled from two skulls found in Hadar (AL 444-2, AL 417). The sculptures were to be represented in a walking stance. The female proportions (AL 417) are estimated from the skeleton of 'Lucy' (AL 288), and the male proportions (AL 444-2) extrapolated from the female ones. Biomechanical and anatomical data (comparison with great apes and humans) are used to reconstruct both dynamic equilibrium and muscular systems. The reconstruction suggests that the fossils moved the pelvis and shoulders extensively when they walked. The hindlimb muscles (such as adductors, gluteal muscles and calf) are fleshy and not or very little tendinous. As indicated by the Laetoli step prints (belonging to a close and contemporaneous species), the foot is adducted during the walk and the support is internal just before take off. In spite of inevitable approximations, such a reconstruction appears to be particularly helpful to bring out morphological and functional traits of the first hominids which are both close to and different from modern humans.

Abstract
The long bones of 72 individuals of extant platyrrhines, belonging to 17 species (11 genera) were studied by regressions of length, diameters and curvature. Cross-sectional shapes at midshaft and axial and bending strength indicators were also calculated. Results show that forelimb bones scale faster than hindlimb bones, for both length and diameters. Curvature scales faster in the femur than in other bones. Strength indicators showed a high variability in the relative importance of axial and bending loadings. Results are consistent with field observations of locomotor behaviour, mainly as regards quadrupedalism versus suspensory locomotion.

Abstract
The procrustes superimposition method is well adapted to heterochronic studies in the field of evolutionary biology. 1) The procrustes method gives a precise and mathematical definition of two of the three heterochronic variables: size and shape. 2) It allows us to describe complex anatomical structures and thus to analyse the whole structure and not just to proceed trait by trait. 3) The approach is statistical and the different hypotheses and results may be statistically tested. 4) When applied to heterochronies the method allows us to test if there is a common shape change related to allometry. In the present study of three species of Hominoid primates, the procrustes superimposition reveals that various heterochronic processes are simultaneously present. Size-age-shape dissociations between species, already present in the first ontogenetic stage, are amplified with growth until adult stage. As compared with that of the chimpanzee, the growth of the gorilla skull is accelerated in terms of size-shape covariation and size alone. The growth of the human skull is neotenic as compared with that of the apes.

Abstract
Changes in pelvic shape in human ontogeny and hominid phylogeny suggest that the heterochronic processes involved differ greatly from the neotenic process traditionally described in the evolution of the skull. The morphology of 150 juvenile and adult pelves of African apes, 60 juvenile and adult pelves of modern humans, two adult pelves and a juvenile hip bone of australopithecines (Sts 14, AL 288, MLD 7) was studied. Multivariate results, ontogenetic allometries, and growth curves confirm that the pelvic growth pattern in humans differs markedly from those of the African apes. The results permit the following conclusions. First, the appearance of a new feature (acetabulo-cristal buttress and cristal tubercle) at the time of human birth allows the addition of traits, such as the attainment of a proportionally narrower pelvis, with more sagittally positioned iliac blades. Pelvic proportions and orientation change progressively in early childhood as bipedalism is practiced. Other changes in pelvic proportions occur later with the adolescent growth spurt. Second, comparison of juvenile and adult australopithecines to modern humans indicates that 1) some pelvic traits of adult Australopithecus resemble those of neonate Homo; 2) the pelvic growth of Australopithecus was probably closer to that of apes, than to that of humans; and 3) prolonged growth in length of hindlimb and pelvis after sexual maturity seems to be a unique feature of Homo. The position of the acetabulo-cristal buttress and of the cristal tubercle on the ilium are similar in adult Australopithecus and neonate Homo suggesting that this feature may have been displaced later during hominid evolution. Progressive displacement of the acetabulo-cristal buttress on the ilium occurs both during hominid evolution (from Australopithecus to Homo sapiens) and human growth (from neonate to adult). This suggests peramorphic evolution of the pelvic morphology of hominids combining three processes of recapitulation (pre-displacement, acceleration and time hypermorphosis). The results lend credence to the hypothesis that no single heterochronic process accounts for all human evolutionary change; rather this reflects a combination of relative changes in growth rhythm and duration, including other perturbations, such as the appearance of new morphological features.

Abstract
Valproate (VPA) is associated with a variety of idiosyncratic hematological effects including thrombocytopenia, inhibition of platelet aggregation, and fibrinogen depletion. This has led some investigators to recommend discontinuation of VPA therapy prior to elective surgical procedures. However, administration of VPA therapy is not altered prior to surgery at the authors' center and no VPA-associated bleeding complications have been observed. Therefore, a retrospective chart review was conducted to verify the clinical observations in patients who had undergone cortical resection while receiving antiepileptic drugs (AEDs). Baseline, surgical, and postoperative laboratory data were available for a total of 313 patients, 111 of whom were receiving VPA and 202 of whom were receiving AEDs without VPA (control patients). Eighty-seven percent of the patients receiving VPA were also being treated with at least one other AED. The control group was approximately equally divided between monotherapy (55%) and polytherapy (45%) treatments. Platelet counts were significantly lower in the control polytherapy (284 +/- 74 x 10(9)/L) and both VPA groups (279 +/- 113 x 10(9)/L) as compared with the control monotherapy group (314 +/- 85 x 10(9)/L). Baseline fibrinogen levels were significantly lower in the VPA than in the control groups (223 +/- 91 g/dl vs. 278 +/- 95 g/dl). Both pre- and postoperatively, the VPA group had lower red blood cells counts, hematocrit, and hemoglobin levels. There was no significant difference between groups in estimated blood loss during surgery or qualitative wound discharge postsurgery. There was only one case of a bleeding complication, which occurred 14 days postoperatively in a patient receiving carbamazepine monotherapy. The results of this study confirm the clinical observations of an absence of bleeding complications in patients receiving VPA therapy at the time of surgery, despite differences in laboratory parameters.

Abstract
The length of the vertebral column of 425 primates (151 prosimians, 76 platyrrhines and 198 catarrhines) was related to body mass from bibliographic sources. Regressions were calculated for the whole sample and separately for the three taxonomic groups quoted above. In parallel, the lengths of the cervical, thoracic and lumbar regions were calculated in a sample of 105 primates (30 prosimians, 19 platyrrhines and 56 catarrhines) and partial correlations established. In all cases except one, the correlation coefficients were significant. Of these, 12 correlations (out of 16) scaled with negative allometry (< 0.33), 4 with positive allometry (> 0.33), and in 6 cases the exponents were not significantly different from the criterion for isometry (0.33). The lumbar region showed the highest variability, mainly in platyrrhines and catarrhines. Results from catarrhines are globally the closest to the expectations of elastic similarity. No obvious direct relationship was found between the length of the vertebral column and the number of vertebrae.

Abstract
Three pelves and eight innominate bones belonging to the fossil species, Australopithecus africanus, Australopithecus robustus, Homo erectus, and Homo sapiens, have been studied biometrically and compared with those of recent humans and apes. A new method of logarithmic factorial analysis suppresses both the size effects and the size reference on pelvic proportions. In combination with principal component analysis it allows specializations to be dissociated from allometrical variations. Some morphological differences on the hominid pelvis prove to be mainly allometric. However, the pelvic morphology of australopithecines is clearly differentiated from that of the genus Homo (including H. erectus, OH 28, KNMER 3227). A. africanus (Sts 14, MLD 7, AL 288) is nearer the humans than is A. robustus (SK 50, SK 3155), which appears to be more specialized in the australopithecine lineage. The pelvic morphology of A. africanus, as integrated with the articular pelvic-femoral link, appears to be biometrically equivalent to that of humans.
