menaquinone-6 and Hypertension

Im Rahmen der vorliegenden Studie sollte der Einfluss des Weichteilschadens auf das klinische Ergebnis nach offener Ellenbogenluxation untersucht werden.. Von Oktober 2008 bis August 2015 wurden insgesamt 230 Patienten mit Ellenbogenluxation behandelt. Diese retrospektive Studie umfasst 21 Fälle von offenen Ellenbogenluxationen. Das Durchschnittsalter der Patienten betrug 49 Jahre alt (20–83 Jahre), 6 Patienten waren weiblich (29%), 15 männlich (71%). Das Bewegungsausmaß des verletzten und unverletzten Ellenbogens wurde erhoben und das funktionelle Ergebnis u. a. mittels Mayo Elbow Performance Score (MEPS), Mayo Wrist Score (MWS) und dem Disability of Arm, Shoulder and Hand (DASH) Score erfasst. Zusätzlich wurden Komplikationen und Revisionsoperationen aufgezeichnet. Der Einfluss des Weichteilschadens (I°/II° offen vs. III° offen) und des Luxationstyps (einfach vs. komplex) auf das klinische Ergebnis wurde analysiert.. Offene Ellenbogenluxationen können mit einem zufriedenstellenden klinischen Ergebnis einhergehen. Insbesondere komplexe offene Ellenbogenluxationen sind jedoch sehr komplikationsbehaftet, wobei neurovaskuläre Komplikationen am häufigsten auftreten.. The current high rate of multidrug-resistant gram-negative bacteria infections among hospitalised patients with cUTIs in the studied area is alarming. Our predictive model could be useful to avoid inappropriate antibiotic treatment and implement antibiotic stewardship policies that enhance the use of carbapenem-sparing regimens in patients at low risk of multidrug-resistance.. The results indicated differential patterns of Inhibition of Return between the High and Low shape/weight based self-worth groups. The High group displayed increased inhibition of return for the shape/weight stimuli relative to control stimuli, while the Low group displayed reduced inhibition of return for the shape/weight stimuli compared to control stimuli. The ED group displayed a similar pattern of results to the High group, but this did not reach significance.. The current findings indicate that young women without an eating disorder who base their self-worth on shape/weight display a pattern of avoidance of shape/weight stimuli that is in direct contrast to those at low risk of developing eating disorders. The possible implications of these specific patterns of inhibition of return across those at varying levels of risk for an eating disorder are discussed along with their implications for intervention approaches.. These results indicated that Sr. An unusually high HbA

Matrix Gla-protein (MGP) is a well-established inhibitor of vascular calcification that is activated by vitamin K-dependent carboxylation. In the setting of vitamin K2 deficiency, dephospho-uncarboxylated MGP (dpucMGP) levels increase, and have been associated with large artery stiffening. Vitamin K2 is also a mitochondrial electron carrier in muscle, but the relationship of vitamin K2 deficiency and dpucMGP with muscle mass is not well understood. We therefore aimed to examine the association of vitamin K2 deficiency and dpucMGP with skeletal muscle mass in patients with hypertension.. We studied 155 hypertensive adults without heart failure. Axial skeletal muscle mass was measured using magnetic resonance imaging from axial steady-state free precession images. DpucMGP was measured with ELISA. Carotid-femoral pulse wave velocity (CF-PWV) was measured from high-fidelity arterial tonometry recordings.. We found an inverse relationship between dpucMGP levels and axial muscle mass, with progressively rising dpucMGP levels correlating with decreasing axial muscle mass. In an unadjusted linear regression model, correlates of dpucMGP included axial skeletal muscle area factor (β = -0.32; P < 0.0001) and CF-PWV (β = 0.31; P = 0.0008). In adjusted analyses, independent correlates of dpucMGP included axial skeletal muscle area factor (β = -0.30; P = 0.0003) and CF-PWV (β = 0.20; P = 0.019).. In hypertensive adults, dpucMGP is independently associated with lower axial muscle mass, in addition to increased large artery stiffness. Further studies are required to investigate the role of vitamin K supplementation in this population.

Vascular calcification (VC) is an active and cell-mediated process that shares many common features with osteogenesis. Knowledge demonstrates that in the presence of risk factors, such as hypertension, vascular smooth muscle cells (vSMCs) lose their contractile phenotype and transdifferentiate into osteoblastic-like cells, contributing to VC development. Recently, menaquinones (MKs), also known as Vitamin K2 family, has been revealed to play an important role in cardiovascular health by decreasing VC. However, the MKs' effects and mechanisms potentially involved in vSMCs osteoblastic transdifferentiation are still unknown. The aim of this study was to investigate the possible role of menaquinone-4 (MK-4), an isoform of MKs family, in the modulation of the vSMCs phenotype. To achieve this, vascular cells from spontaneously hypertensive rats (SHR) were used as an in vitro model of cell vascular dysfunction. vSMCs from Wistar Kyoto normotensive rats were used as control condition. The results showed that MK-4 preserves the contractile phenotype both in control and SHR-vSMCs through a γ-glutamyl carboxylase-dependent pathway, highlighting its capability to inhibit one of the mechanisms underlying VC process. Therefore, MK-4 may have an important role in the prevention of vascular dysfunction and atherosclerosis, encouraging further in-depth studies to confirm its use as a natural food supplement.
