Longevity and stroke: a study on 1.176 GeHA 90+ Italian sibs

Preface: The improvements of the social-environmental conditions, and medical cares and the quality of life caused a general improvement of the health status of the population, with a consequent reduction of the overall morbidity and mortality, resulting in an increase of life expectancy that has rose dramatically in the last century. Stroke represents the 3rd cause of death and 1st cause of disability in Europe and in Italy. Aim: The aim of this research is to explore the prevalence of stroke in 1.176 90+ Italian sibs, collected from the north, centre and south of the peninsula, and examine the presence of functional and cognitive disability in the stroke affected sibs. Materials and Methods: We divided our sample in three main categories a)Stroke free(960 subjects, 88.72%), b)Young age stroke, reported age of Stroke incidence < 85 y.o.(42 subjects, 3.88%), c)Old age stroke, reported age of Stroke incidence ≥ 85y.o.(80 subjects, 7.39%). We examine cognitive impairment using the MMSE and functional disability using the ADL scale, the chair stand and hand-grip test. The three groups for each test have been analysed according the following parameters: age at interview, sex, ability to understand the questions, can the participant walk 500 m without help, smoke habit, alcohol daily consumption, presence of serious memory impairments (e.g. dementia), Daily Exercise or daily light housework, History of arthritis. Results: After performing mulrivariate analysis, amazingly the young ictus group had worst performance in all the cognitive and functional variables.

Progenitori endoteliali nei pazienti con Chronic Kidney Disease - Mineral and Bone Disorder (CKD-MBD) in fase uremica: effetti del trattamento con vitamina D.

L'insufficienza renale cronica (CKD) è associata ad un rischio cardiovascolare più elevato rispetto alla popolazione generale: fattori come uremia, stress ossidativo, età dialitica, infiammazione, alterazioni del metabolismo minerale e presenza di calcificazioni vascolari incidono fortemente sulla morbosità e mortalità per cause cardiovascolari nel paziente uremico. Diversi studi hanno verificato il coinvolgimento dei progenitori endoteliali (EPC) nella malattia aterosclerotica ed è stato dimostrato che esprimono osteocalcina, marcatore di calcificazione. Inoltre, nella CKD è presente una disfunzione in numero e funzionalità delle EPC. Attualmente, il ruolo delle EPC nella formazione delle calcificazioni vascolari nei pazienti in dialisi non è stato ancora chiarito. Lo scopo della tesi è quello di studiare le EPC prelevate da pazienti con CKD, al fine di determinarne numero e fenotipo. È stato anche valutato l'effetto del trattamento in vitro e in vivo con calcitriolo e paracalcitolo sulle EPC, dato il deficit di vitamina D dei pazienti con CKD: il trattamento con vitamina D sembra avere effetti positivi sul sistema cardiovascolare. Sono stati valutati: numero di EPC circolanti e la relativa espressione di osteocalcina e del recettore della vitamina D; morfologia e fenotipo EPC in vitro; effetti di calcitriolo e paracalcitolo sull’espressione di osteocalcina e sui depositi di calcio. I risultati dello studio suggeriscono che il trattamento con vitamina D abbia un effetto positivo sulle EPC, aumentando il numero di EPC circolanti e normalizzandone la morfologia. Sia calcitriolo che paracalcitolo sono in grado di ridurre notevolmente l’espressione di OC, mentre solo il paracalcitolo ha un effetto significativo sulla riduzione dei depositi di calcio in coltura. In conclusione, il trattamento con vitamina D sembra ridurre il potenziale calcifico delle EPC nell’uremia, aprendo nuove strade per la gestione del rischio cardiovascolare nei pazienti affetti da CKD.

The impact of cardiac rehabilitation on lifestyles, psychological correlates and the clinical course of cardiac disease

Objectives: The aim of this research was to evaluate the impact of Cardiac Rehabilitation (CR) on risky lifestyles, quality of life, psychopathology, psychological distress and well-being, considering the potential moderating role of depression, anxiety and psychosomatic syndromes on lifestyles modification. The influence of CR on cardiac morbidity and mortality was also evaluated. Methods: The experimental group (N=108), undergoing CR, was compared to a control group (N=85) of patients affected by cardiovascular diseases, not undergoing CR, at baseline and at 1-month, 6- and 12-months follow-ups. The assessment included: the Structured Clinical Interview for DSM-IV, the structured interview based on Diagnostic Criteria for Psychosomatic Research (DCPR), GOSPEL questionnaire on lifestyles, Pittsburgh Sleep Quality Index, Morisky Medication Adherence Scale, MOS 36-Item Short Form Health Survey, Symptom Questionnaire, Psychological Well-Being Scale and 14-items Type D Scale. Results: Compared to the control group, CR was associated to: maintenance of the level of physical activity, improvement of correct dietary behaviors and stress management, enhancement of quality of life and sleep; reduction of the most frequently observed psychiatric diagnoses and psychosomatic syndromes at baseline. On the contrary, CR was not found to be associated with: healthy dietary habits, weight loss and improvement on medications adherence. In addition, there were no relevant effects on sub-clinical psychological distress and well-being, except for personal growth and purpose in life (PWB). Also, CR did not seem to play a protective role against cardiac recurrences. The presence of psychosomatic syndromes and depressive disorders was a mediating factor on the modification of specific lifestyles. Conclusions: The findings highlight the need of a psychosomatic assessment and an evaluation of psychological sub-clinical symptomatology in cardiac rehabilitation, in order to identify and address specific factors potentially associated with the clinical course of the heart disease.

The elderly health status and its correlation with ageing biomarkers: the European Project Mark-Age

According to the latest statistics projections formulated by Eurostat, the proportion of elderly EU-27’s population aged over 65 years old is predicted to increase from 17.5 % in 2011 to 29.5 % by 2060. This "population explosion" makes extremely important to identify the different genetic and molecular mechanisms which underpin the morbidity and mortality along with new strategies able to counteract or slow down its progress. In this scenario fits the European Project MARK-AGE whose aim was to identify a robust set of biomarkers of human ageing able to discriminate between chronological and biological ageing and to derive a model for healthy ageing through the analysis of three populations from different European countries, supposed to be characterized by different ageing rate: 1. Subjects representing the “Normal” or “Physiological” aging. 2. Subjects representing the “successful” or “decelerate” aging 3. Subjects representing the “accelerated” aging. The aim of this work was to recruit and characterize volunteers, to perform an accurate analysis of the health status of elderly recruited subjects (60-79 years) verifying any possible dissimilarity in their aging trajectories, to identify a set of robust ageing biomarkers and investigate possible correlations between ageing biomarkers and health status of recruited volunteers. The model proposed by MARK-AGE Project regarding different ageing trajectories has been confirmed and several ageing biomarkers have been identified.
