Progressive right ventricular dysfunction and exercise impairment in patients with heart failure and diabetes mellitus: insights from the T.O.S.CA. R…
2022
Abstract Background Findings from the T.O.S.CA. Registry recently reported that patients with concomitant chronic heart failure (CHF) and impairment of insulin axis (either insulin resistance—IR or diabetes mellitus—T2D) display increased morbidity and mortality. However, little information is available on the relative impact of IR and T2D on cardiac structure and function, cardiopulmonary performance, and their longitudinal changes in CHF. Methods Patients enrolled in the T.O.S.CA. Registry performed echocardiography and cardiopulmonary exercise test at baseline and at a patient-average follow-up of 36 months. Patients were divided into three groups based on the degree of insulin impairmen…
Short-Time Ocular Ischemia Induces Vascular Endothelial Dysfunction and Ganglion Cell Loss in the Pig Retina
2019
Visual impairment and blindness are often caused by retinal ischemia-reperfusion (I/R) injury. We aimed to characterize a new model of I/R in pigs, in which the intraocular pathways were not manipulated by invasive methods on the ocular system. After 12 min of ischemia followed by 20 h of reperfusion, reactivity of retinal arterioles was measured in vitro by video microscopy. Dihydroethidium (DHE) staining, qPCR, immunohistochemistry, quantification of neurons in the retinal ganglion cell layer, and histological examination was performed. Retinal arterioles of I/R-treated pigs displayed marked attenuation in response to the endothelium-dependent vasodilator, bradykinin, compared to sham-tre…
Ejaculation Disorders in Male Patients with Cancer: A Systematic Review and Meta-Analysis of Prevalence
2021
PURPOSE: Ejaculatory dysfunction (EjD) and erectile dysfunction after cancer treatment are clinically important complications, but their exact prevalence by various kinds of cancer site and type of treatment is unknown. The aim of this systematic review and meta-analysis was to examine the available evidence and provide pooled estimates for prevalence of EjD and erectile dysfunction in relation to all cancer sites and identify characteristics associated with EjD in cancer patients. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of cross-sectional and case-control studies. We searched 4 electronic databases (Medline®, CINAHL, PsychInfo and Embase®) until July 22, 2…
Pathogenesis and molecular mechanisms of anderson–fabry disease and possible new molecular addressed therapeutic strategies
2021
Anderson–Fabry disease (AFD) is a rare disease with an incidenceof approximately 1:117,000 male births. Lysosomal accumulation of globotriaosylceramide (Gb3) is the element characterizing Fabry disease due to a hereditary deficiency α-galactosidase A (GLA) enzyme. The accumulation of Gb3 causes lysosomal dysfunction that compromises cell signaling pathways. Deposition of sphingolipids occurs in the autonomic nervous system, dorsal root ganglia, kidney epithelial cells, vascular system cells, and myocardial cells, resulting in organ failure. This manuscript will review the molecular pathogenetic pathways involved in Anderson–Fabry disease and in its organ damage. Some studies reported that i…

Oxidative stress in cardiovascular disease: successful translation from bench to bedside?
2007
Over the last decades, sound evidence has been generated that oxidative stress is one of the most potent inductors of endothelial dysfunction and is involved at all stages of atherosclerotic plaque evolution.1,2 Experimental and animal models provide a clear association between the amount of oxidative challenge and reversible vascular dysfunction that can be observed before permanent alterations of the vessel wall occur. Article p 1367 Important for cardiovascular biology is the consumption of nitric oxide (NO) by reactive oxygen species. Endothelium relaxant factor is a central molecule in vascular homeostasis as a modulator of endothelial tone and reactivity.3 It is produced by NO synthas…
Risk-adapted management of pulmonary embolism
2017
The presence and severity of right ventricular (RV) dysfunction is a key determinant of prognosis in the acute phase of pulmonary embolism (PE). Risk-adapted treatment strategies continue to evolve, tailoring initial management to the clinical presentation and the functional status of the RV. Beyond pharmacological and, if necessary, mechanical circulatory support, systemic thrombolysis remains the mainstay of treatment for hemodynamically unstable patients; in contrast, it is not routinely recommended for intermediate-risk PE. Catheter-directed pharmacomechanical reperfusion treatment represents a promising option for minimizing bleeding risk; for reduced-dose intravenous thrombolysis, the…
Minimally Invasive Sacroiliac Joint Arthrodesis: Experience in a Prospective Series with 24 Patients
2014
Background: Sacroiliac (SI) joint pain conservative treatments show poor outcomes. Hypothesis: surgical treatment will show better results. Patients and methods: Prospective series: 24 patients undergoing SI fusion after failure of medical treatment and showing temporary relief with SI infiltration. Period: Nov 2009-July 2013. Gender: 9/15. 11 cases bilaterally (all ). Age: 32-71 years (mean 47.4 years). Height: 161-178 cm (mean 168.2 cm). Weight: 56-84 kg (mean 68.4 kg). Etiology: 12 degenerative/spontaneous, 7 fall on buttocks, 3 coincident with lumbar disc and 2 with lumbar posterolateral fusion. Exclusion criteria: ankylosing spondylitis, osteitis condensans ilii, sacro-iliac joint arth…
Conclusion: Tying It All Together
2018
In this last section of the book, I will try and tie all the earlier discussions together. Expanding on the previous sections, I conclude that from the three concepts, the first is of most importance—the internal dynamics of the music industries. The concept has significant explanatory power as a factor on its own, as well as having significant impact on the two other factors. The internal structures and the (dysfunctional) nature of the music industries clearly create internal frustrations and external hostility. And more importantly, it seems to prevent the music industries from acting on the digital potential that appears.
The clinical trait self-criticism and its relation to psychopathology: A systematic review – Update
2019
Abstract Background Self-criticism represents a central phenomenon in a variety of mental disorders. The review looks at the recent body of literature (2012–2018) to summarize the relation of self-criticism and psychopathology beyond depression and aims at detecting how different conceptualizations of self-criticism with psychoanalytical, psychodynamic, or cognitive-evolutionary background are related to psychopathology. Furthermore, latest treatment approaches for dysfunctional forms of self-criticism are reviewed. Methods The literature research of five databases (PsycINFO, PSYNDEX, PubMed, Medline, and Cochrane Library) took place in August 2018. Inclusion criteria for studies to enter t…
