Spirituality and heart failure: a systematic review

Objectives: Heart failure (HF) is a frequent chronic disease with disturbing symptoms and complex treatments, associated with depression and lower quality of life. Some studies have shown that spirituality and religiosity may be relevant in these patients. We aimed to systematically review the medical literature on spirituality and religiosity in patients with HF. Methods: Major databases for studies investigating the effect of spirituality and religiosity in people affected by HF were searched from inception until 26th April 2023. Studies with clear definition of spirituality or religiosity, validated diagnosis of HF, and reporting outcomes of interest (i.e., incidence of mortality, cardiovascular outcomes, and quality of life) were included. Results: Among 810 non-duplicate records, we screened the full texts of 25 works. After excluding 18 studies, we included 7 studies (3 observational and 4 interventional) comprising 1234 HF patients followed up over a median of 3 months. Definitions of spirituality and religiosity were heterogeneous among the studies. The intervention studies showed improvements in quality-of-life parameters, some cardiovascular outcomes, or mortality, and the observational studies showed significant associations with these outcomes. Conclusions: Despite the extreme heterogeneity of the populations included, of the definition of spirituality and religiosity, and of the interventions in the few studies that included it, all the studies reported some positive associations with the outcomes examined. Spirituality/religiosity is an aspect not generally taken into account in the usual practice of medicine and can potentially contribute to improving the conditions of patients with HF, a chronic disease with unfavorable prognosis

An extension of Broms’ theory to unsaturated soils

This paper presents an analytical method to predict the horizontal capacity of piles in unsaturated soils. The method extends the well-known Broms approach to account for the combined effect of the groundwater table and the apparent cohesion of the unsaturated soil above it. Similar to the original formulation of Broms, the present method calculates the maximum horizontal force and bending moment that can be sustained by the pile for two different head fixities (i.e. free-head and restrained-head) as a function of non-dimensional parameters that depend on the geometry and flexural resistance of the pile (i.e. yielding moment), the soil resistance and the type of failure mechanism (i.e. short, intermediate or long pile). Compared to Broms’ solution, the method introduces additional non-dimensional parameters that relate the water retention behaviour of the soil to the geometry of the pile. The proposed formulation accurately predicts the lateral capacity of piles as experimentally measured in previous works. Results confirm that consideration of the partially saturated state of the soil above the groundwater table is essential for a reliable estimate of the horizontal capacity of piles

Hygro-Thermal Modelling of Earthen Materials for Building Applications

Earth is a building material with low carbon emissions compared to conventional concrete or fired bricks. Earthen materials have an excellent capacity to regulate indoor hygrothermal conditions allowing for a better comfort with reduced heating and cooling needs during the life cycle of the building. The present paper presents a theoretical framework to investigate the hygro-thermal response of earthen materials by coupling the principles of unsaturated soil mechanics combined with the thermodynamics of porous media. The degree of coupling between the two variables (temperature and relative humidity or water content) depends on the values of the water and vapour permeability functions which, in turns, depend on the water retention curve of the material. Results shows that, in the hygroscopic domain, the hydro-thermal coupling is more influenced by the saturated permeability than by the vapour diffusion coefficient

Measurement of the production cross section ratio sigma(chi b2(1P))/sigma(chi b1(1P)) in pp collisions at root s=8TeV

A measurement of the production cross section ratio sigma(chi b2(1P))/sigma(chi b1(1P)) is presented. The chi b1 (1P) and chi b2 (1P) bottomonium states, promptly produced in pp collisions at root s = 8TeV, are detected by the CMS experiment at the CERN LHC through their radiative decays chi b1,2(1P) -> Y(1S) + gamma. The emitted photons are measured through their conversion to e(+) e(-) pairs, whose reconstruction allows the two states to be resolved. The Y(1S) is measured through its decay to two muons. An event sample corresponding to an integrated luminosity of 20.7 fb(-1) is used to measure the cross section ratio in a phase-space region defined by the photon pseudorapidity, vertical bar eta(gamma)vertical bar < 1.0; the Y(1S) rapidity, vertical bar y(Y)vertical bar < 1.5; and the Y(1S) transverse momentum, 7 < p(T)(Y) < 40 GeV. The cross section ratio shows no significant dependence on the.(1S) transverse momentum, with a measured average value of 0.85 +/- 0.07 (stat + syst) +/- 0.08 (BF), where the first uncertainty is the combination of the experimental statistical and systematic uncertainties and the second is from the uncertainty in the ratio of the chi b branching fractions
