Association between sexual frequency and all-cause mortality in young and middle-aged patients with hypertension: a cohort study of patient data from the National Health and Nutrition Examination Survey 2005-2014.

Background: Sexual activity appears to have protective effects on overall and cardiovascular health.

Aim: We hypothesized that decreased sexual frequency would be an early predictor of all-cause mortality in young and middle-aged patients (20 to 59 years old) with hypertension.

Methods: A total of 4565 patients with hypertension (55.

Topology Optimization for FDM Parts Considering the Hybrid Deposition Path Pattern.

Based on a solid orthotropic material with penalization (SOMP) and a double smoothing and projection (DSP) approach, this work proposes a methodology to find an optimal structure design which takes the hybrid deposition path (HDP) pattern and the anisotropic material properties into consideration. The optimized structure consists of a boundary layer and a substrate. The substrate domain is assumed to be filled with unidirectional zig-zag deposition paths and customized infill patterns, while the boundary is made by the contour offset deposition paths.

Tetra-aqua-bis-[4-(4H-1,2,4-triazol-4-yl)benzoato-κN]copper(II) dihydrate.

In the title compound, [Cu(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·2H(2)O, the Cu(II) atom lies on an inversion center and is six-coordinated by two N atoms from two 4-(1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules in a distorted octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds lead to a three-dimensional supra-molecular network. Intra-molecular O-H⋯N hydrogen bonds and π-π inter-actions between the benzene rings and between the benzene and triazole rings [centroid-centroid distances = 3.

Diaqua-bis-[4-(4H-1,2,4-triazol-4-yl)benzoato-κO,O']nickel(II).

In the title compound, [Ni(C(9)H(6)N(3)O(2))(2)(H(2)O)(2)], the Ni(II) atom lies on a twofold rotation axis and is six-coordinated by two bidentate chelating 4-(1,2,4-triazol-4-yl)benzoate ligands and two water mol-ecules in a distorted octa-hedral geometry. Inter-molecular O-H⋯N hydrogen bonds link the complex mol-ecules into a two-dimensional network parallel to (010).
