Published: November 2009

The title compound, C(25)H(22)O(2), was synthesized via the three-component coupling of benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯O hydrogen bonds. The dimers are further connected into a three-dimensional network by π-π aromatic stacking inter-actions involving the naphthalene ring system, with centroid-centroid separations of 3.695 (7) Å.

Background: Non-invasive, continuous blood pressure monitoring technologies require additional validation beyond standard cuff-based methods. This study evaluates a non-invasive, multiparametric wearable cuffless blood pressure (BP) diagnostic monitor across all hypertension classes with diverse subjects.

Methods: A prospective, multicenter study assessed Nanowear's SimpleSense-BP performance, including induced and natural BP changes, significant BP variations (Systolic BP (SBP) ≥ ± 15 mm Hg and Diastolic BP (DBP) ≥ ± 10 mm Hg), and reference input value validity over 4 weeks.

To investigate if progression of coronary artery calcification (CAC) in patients with systemic lupus erythematosus (SLE) is associated with renal and traditional cardiovascular risk factors as well as incidence of myocardial infarctions. CAC progression was evaluated by cardiac computed tomography (CT) at baseline and after 5 years. Multivariable Poisson regression was applied to investigate associations between CAC progression and baseline values for traditional cardiovascular risk factors, CAC, SLE disease duration, lupus nephritis, and renal function.

Background: Patients on long-term dialysis for end-stage kidney disease have a high mortality rate, predominantly due to sudden cardiac death (SCD), which is associated with an increased risk of arrhythmias compared to the general population. Thus, the current systematic review and meta-analysis aimed to investigate the incidence of SCD among dialysis patients at risk of arrhythmia.

Methods: This systematic review and meta-analysis followed the PRISMA guidelines.

Background: Transcutaneous electrical stimulation after breast cancer surgery has been utilized for various purposes, but the full efficacy of this treatment approach on postoperative symptoms remains unclear.

Aim: This study aimed to answer the question: Does transcutaneous electrical nerve stimulation significantly impact postoperative patient outcomes in individuals undergoing breast cancer surgery?

Methods: A systematic review of randomized controlled trials was conducted. Because of the limited number of studies included, it was not feasible to perform a meta-analysis.
