Assessing infertility-related stress: The factor structure of the Fertility Problem Inventory in Italian couples undergoing infertility treatment

2015

The factor structure of the Fertility Problem Inventory (FPI) and its invariance across gender were examined in Italian couples undergoing infertility treatment. About 1000 subjects (both partners of 500 couples) completed two questionnaires prior to commencing infertility treatment at a private Clinic in Palermo, Italy. Confirmatory Factor Analysis demonstrated that the original factor structure of the FPI was partially confirmed. Two correlated factors (Infertility Life Domains and Importance of Parenthood) were obtained via a post hoc Exploratory Factor Analysis. Finally, the invariance of this factor structure across gender was confirmed. The study supported the relevance of two interre…

Sexual satisfaction in male infertility.

1999

Infertility is proposed to be a continuing stressor for couples suffering from involuntary childlessness. A long duration of the desire for a child and, correspondingly, a longer period of diagnostic and treatment procedures could have a negative impact on sexual satisfaction, thus leading to an unfavorable psychological circuit. The present evaluation should clarify the state of sexual satisfaction and relationships, with relevant parameters in 68 men with fertility problems, of couples with involuntary childlessness. Subjects reported relatively high average levels of present sexual satisfaction with only nonsignificant lower scores (p = .08) compared to recalled sexual satisfaction prior…

The role of reactive oxygen species in obesity therapeutics.

2019

Obesity is a major risk factor for multiple severe health conditions, including cardiovascular diseases, diabetes and cancer. It is often related to an increased risk of morbidity and mortality and, as it can be accompanied by non-fatal health problems, quality of life is seriously reduced due to related conditions including hypertension, sleep apnea, osteoarthritis, respiratory problems and infertility. Evidence suggests that oxidative stress is related to obesity and its complications. In obese patients, there is an increase in levels of reactive oxygen species and nitrogen species and antioxidant defenses are undermined in comparison to normal-weight counterparts. In addition, these para…

The effect of depression and the reframing strategy on the level of satisfaction with family life in infertile and post-miscarriage couples: dyadic a…

2021

Pary zmagające się z bezpłodnością, jak i te po doświadczeniu poronienia poddawane są działaniu wielu stresorów, w obliczu których reagują lękiem, żalem i depresją, co negatywnie wpływa na płodność i wiąże się ze zwiększonym ryzykiem poronienia. Stosowanie różnych strategii radzenia sobie wydaje się mieć różny wpływ na stres związany z niepłodnością i doświadczeniami poronienia. Celem pracy było zbadanie związków miedzy depresyjnością związaną z niepłodnością i poronieniem a zadowoleniem z życia rodzinnego oraz roli stosowania strategii przekształcenia znaczenia sytuacji w przewidywaniu zadowolenia z życia rodzinnego w grupie depresyjnych par bezpłodnych oraz po doświadczeniu poronienia.

Empirical Equations for the Direct Definition of Stress–Strain Laws for Fiber-Section-Based Macromodeling of Infilled Frames

2018

Equivalent strut macromodels are largely used to model the influence of infill walls in frame structures due to their simplicity and effectiveness from a computational point of view. Despite these advantages, which are fundamental to carrying out seismic simulation of complex structures, equivalent struts are phenomenological models and therefore have to conventionally account for the influence of really large amounts of geometrical and mechanical variables with a relatively simple inelastic response. Mechanical approaches, generally used to evaluate the force-displacement curve of a strut, are based on hypothesizing the damage mechanism that will occur for an infill-frame system subject to…

Definition of a fiber macro-model for nonlinear analysis of infilled frames

2017

A common way to model infill-frame interaction is the use equivalent strut macromodels. In most cases these are compression only resistant truss elements defined with a multi-linear axial-force / axial-displacement law. The main difficulty in using this approach is to correctly calibrate such a force-displacement curve (slope of ascending and post-peak branches, critical yielding, peak and residual forces) because of the large number of variables (mechanical and elastic properties of materials) and the different possible damage mechanisms activated for the frame-infill system. Another possible way is using fiber-section elements as diagonal struts. In this case the force-displacement law is…

Action of low doses of Aspirin in Inflammation and Oxidative Stress induced by aβ

2019

Aspirin has been used as anti-inflammatory and anti-aggregate for decades but the precise mechanism(s) of action after the presence of the toxic peptide Aβ1-42 in cultured astrocytes remains poorly resolved. Here we use low-doses of aspirin (10-7 M) in astrocytes in primary culture in presence or absence of Aβ1-42 toxic peptide. We noted an increase of cell viability and proliferation with or without Aβ1-42 peptide presence in aspirin treated cells. In addition, a decrease in apoptosis, determined by Caspase 3 activity and the expression of Cyt c and Smac/Diablo, were detected. Also, aspirin diminished necrosis process (LDH levels), pro-inflammatory mediators (IL-β and TNF-α) and NF-ᴋB prot…
