Electrocardiographic Diagnosis of Atrial Tachycardia: Classification, P-Wave Morphology, and Differential Diagnosis with Other Supraventricular Tachy…
2015
Atrial tachycardia is defined as a regular atrial activation from atrial areas with centrifugal spread, caused by enhanced automaticity, triggered activity or microreentry. New ECG classification differentiates between focal and macroreentrant atrial tachycardia. Macroreentrant atrial tachycardias include typical atrial flutter and other well characterized macroreentrant circuits in right and left atrium. Typical atrial flutter has been described as counterclockwise reentry within right atrial and it presents a characteristic ECG “sawtooth” pattern on the inferior leads. The foci responsible for focal atrial tachycardia do not occur randomly throughout the atria but tend to cluster at chara…
Up-Regulation of leucocytes Genes Implicated in Telomere Dysfunction and Cellular Senescence Correlates with Depression and Anxiety Severity Scores
2012
BACKGROUND: Major depressive disorder (MDD) is frequently associated with chronic medical illness responsible of increased disability and mortality. Inflammation and oxidative stress are considered to be the major mediators of the allostatic load, and has been shown to correlate with telomere erosion in the leucocytes of MDD patients, leading to the model of accelerated aging. However, the significance of telomere length as an exclusive biomarker of aging has been questioned on both methodological and biological grounds. Furthermore, telomeres significantly shorten only in patients with long lasting MDD. Sensitive and dynamic functional biomarkers of aging would be clinically useful to eval…
The Impact of COVID-19 Quarantine on Patients With Dementia and Family Caregivers: A Nation-Wide Survey
2021
IntroductionPrevious studies showed that quarantine for pandemic diseases is associated with several psychological and medical effects. The consequences of quarantine for COVID-19 pandemic in patients with dementia are unknown. We investigated the clinical changes in patients with Alzheimer’s disease and other dementias, and evaluated caregivers’ distress during COVID-19 quarantine.MethodsThe study involved 87 Italian Dementia Centers. Patients with Alzheimer’s Disease (AD), Dementia with Lewy Bodies (DLB), Frontotemporal Dementia (FTD), and Vascular Dementia (VD) were eligible for the study. Family caregivers of patients with dementia were interviewed by phone in April 2020, 45 days after …
Magnesium in Aging, Health and Diseases
2021
Several changes of magnesium (Mg) metabolism have been reported with aging, including diminished Mg intake, impaired intestinal Mg absorption and renal Mg wasting. Mild Mg deficits are generally asymptomatic and clinical signs are usually non-specific or absent. Asthenia, sleep disorders, hyperemotionality, and cognitive disorders are common in the elderly with mild Mg deficit, and may be often confused with age-related symptoms. Chronic Mg deficits increase the production of free radicals which have been implicated in the development of several chronic age-related disorders. Numerous human diseases have been associated with Mg deficits, including cardiovascular diseases, hypertension and s…
Frailty and leucocyte count are predictors of all-cause mortality and hospitalization length in non-demented institutionalized older women.
2017
Alteration in the immune system such as the number of white blood cells count (WBC) has been associated with frailty syndrome but their role in institutionalized older individuals have been rarely investigated. We evaluated the relationships between white blood cell subtypes, geriatric assessment, depression and frailty syndrome based on the criteria of physical phenotype. In particular, we aimed to analyze by a two-year follow-up and prospective study the predictive value of alterations in WBC, frailty and functional impairment in terms of hospitalizations and all-cause mortality in institutionalized older women. There was a significant and inverse correlation between the frailty score and…
PSYCHOLOGY STUDENTS PERSONALITY TRAITS AND MOTIVATION TO CHOOSE STUDIES
2016
The sample consisted of 83 first course academic and professional psychology program students aged 18-43 years. Research instruments: 1) Demographic survey; 2) BFI (Big Five Inventory, Benet – Martinez & John, 1998), adapted version in Latvian (Austers, 2007); 3) The assessment of psychology studies motivation. Key findings: The most important motivating factors for psychology studies in this sample are interest in psychology and the desire to help. Personality traits are related to the choice of profession motives: Agreeableness and Conscientiousness are positively correlated with the desire to help, Extroversion with a sense of capability for the profession, Neuroticism - with a uncer…
Voltammetric Analysis of Platinum in Environmental Matrices
2014
This article will summarize measurement data for Pt in different environmental samples obtained by the authors using a recently developed approach by voltammetric analysis. A fast accumulation of platinum and rhodium in the environmental and biological matrices has been observed in the last few years and concern has arisen about potential environmental and health risks. Voltammetry was used for the determination of Pt and Rh in airborne particulate collected in Palermo, Italy. Possible interferences by other environmental metals have also been evaluated. All samples show concentrations of Pt and Rh above average upper crust values. The Pt and Rh concentrations in particulate samples collect…
Influence of Burnout and Feelings of Guilt on Depression and Health in Anesthesiologists
2020
Background and objective: The WHO has included burnout as an occupational phenomenon in the ICD-11. According to the WHO, burnout is a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. The study aimed to evaluate the influence of feelings of guilt and burnout on health in Polish anesthesiologists. Alcohol and tobacco intake, psychosomatic disorders, and depression were assessed. Methods: The study had a non&ndash
Dynamics of the general factor of personality: A predictor mathematical tool of alcohol misuse
2020
[EN] There are few studies developed about the general factor of personality (GFP) dynamics. This paper uses a dynamical mathematical model, the response model, to predict the short-term effects of a dose of alcohol on GFP and reports the results of an alcohol intake experiment. The GFP dynamical mechanism of change is based on the unique trait personality theory (UTPT). This theory proposes the existence of GFP, which occupies the apex of the hierarchy of personality. An experiment with 37 volunteers was performed. All the participants completed The five-adjective scale of the general factor of personality (GFP-FAS) in trait-format (GFP-T) and state-format (GFP-S) before alcohol consumptio…
Interoceptive Abilities in Inflammatory Bowel Diseases and Irritable Bowel Syndrome
2020
International audience; Alexithymia is usually described by three main dimensions difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and externally oriented thinking (EOT). The most commonly used questionnaire investigating alexithymia, the Toronto Alexithymia Scale (TAS-20), supports this three-factor structure. One important assumption is that alexithymia severity is associated to vulnerability to somatic diseases, among them gastrointestinal disorders. However, the association between alexithymia and gastrointestinal disorders is not systematic, thus questioning the role of alexithymia as a vulnerability factor for those illnesses. A recent factor analysis sugge…
