Homocysteinemia and Depression in Community-Dwelling Older Adults: The Cohort Longitudinal Study “InveCeAb” (Brain Aging in Abbiategrasso)

引用

Health 2024年第1期16卷 22-36页

作者： Mauro Colombo annalisa Davin Elena Rolandi Michele Rossi Riccardo Ferrari Erica Spina Antonio Guaita Golgi Cenci Foundation Abbiategrasso Italy

Depression is a major health problem, especially for elderly people. According to the “homocysteine hypothesis of depression”, high homocysteine levels may cause depression of mood via cerebrovascular diseases. Whilst biologically plausible, such hypothesis needs yet confirmation. We aimed at: 1) studying the relationships between homocysteinemia (HCY) and depression in a community-dwelling cohort of people aged 70 to 75 years at baseline;2) investigating plasma levels of HCY and 3) comparing these levels between males and females, in the same population. We exploited the data from four waves (2010, 2012, 2014 and 2018) of the longitudinal study “InveCeAb”, with specific regard towards mood assessment, by Geriatric Depression Scale (GDS) scoring, and diagnosis of clinically relevant or subthreshold depression. HCY plasma levels were measured in the waves 2012, 2014 and 2018. Sample attrition was due mainly to death or overall worsening. No statistically significant differences were found in plasma homocysteine levels in each wave, according to depressive symptoms. No correlations were found between plasma HCY levels in each wave with their corresponding GDS scores, even after adjustment for folate and cobalamin blood concentrations. Dichotomized levels of HCY (≤15 vs >15 μM/l) were not associated with dichotomized GDS scores (≤4 vs higher), clinically relevant and subthreshold depression diagnosis and any antidepressive use, in any wave. First (2012) HCY levels increased with participants’ increasing age, cross-sectionally. Listwise HCY concentrations decreased along the 3 waves. HCY levels were always higher in males than in females. Our results may challenge the “homocysteine hypothesis” of depression, whilst supporting the role of high homocysteinemia as a marker of overall bad health.

Stability of Nonlinear Differential-Algebraic Systems Via Additive Identity

引用

IEEE/CAA Journal of Automatica Sinica 2020年第4期7卷 929-941页

作者： Pierluigi Di Franco Giordano Scarciotti Alessandro astolfi the Electrical and Electronic Engineering Department Imperial College LondonLondon SW72AZUK

The stability analysis for nonlinear differentialalgebraic systems is addressed using tools from classical control theory. Sufficient stability conditions relying on matrix inequalities are established via Lyapunov Direct Method. In addition, a novel interpretation of differential-algebraic systems as feedback interconnection of a purely differential system and an algebraic system allows reducing the stability analysis to a smallgain-like condition. The study of stability properties for constrained mechanical systems, for a class of Lipschitz differential-algebraic systems and for an academic example is used to illustrate the theory.

On the Numerical Solution to a Nonlinear Wave Equation Associated with the First Painlev Equation:an Operator-Splitting Approach

引用

Chinese Annals of Mathematics,Series B 2013年第2期34卷 237-254页

作者： Roland GLOWINSKI annalisa QUAINI Department of Mathematics University of Houston4800 Calhoun RdHouston(TX) 77204USA Laboratoire Jacques-Louis Lions Universit Pierre et Marie Curie4Place Jussieu75252 Paris CEDEX 05France

The main goal of this article is to discuss the numerical solution to a nonlinear wave equation associated with the first of the celebrated Painlevd transcendent ordinary differential equations. In order to solve numerically the above equation, whose solutions blow up in finite time, the authors advocate a numerical methodology based on the Strang＇s symmetrized operator-splitting scheme. With this approach, one can decouple nonlinearity and differential operators, leading to the alternate solution at every time step of the equation as follows：（i） The first Painlevd ordinary differential equation, （ii） a linear wave equation with a constant coefficient. Assuming that the space dimension is two, the authors consider a fully discrete variant of the above scheme, where the space-time discretization of the linear wave equation sub-steps is achieved via a Galerkin/finite element space approximation combined with a second order accurate centered time discretization scheme. To handle the nonlinear sub-steps, a second order accurate centered explicit time discretization scheme with adaptively variable time step is used, in order to follow accurately the fast dynamic of the solution before it blows up. The results of numerical experiments are presented for different coefficients and boundary conditions. They show that the above methodology is robust and describes fairly accurately the evolution of a rather ＂violent＂ phenomenon.
