- Patients with chronic conditions like hypertension may experience many negative emotions which endorse the development of anxiety and depression symptomatology, thus they increase their risk for poor quality of life. Several studies have shown an association between symptoms of psychological distress and hypertension. In this study we aimed to quantify the link between depression, cardiophobia and quality of life in hypertensive patients. A cross-sectional design was employed. A sample of 197 hypertensive patients (89 men-108 women, mean age 53 years, SD=12 ranged 25-78) from a university outpatient hypertension clinic in Greece participated. Ninety-four (47.7%) of the participants suffered from essential grade I hypertension; 68 (34.5%) were grade II; 16 (8.1%) were categorized as grade III, while only 11 (5.6%) patients were recorded as normotensives with high normal values. The questionnaires included: (a) question for the recording of social-demographic characteristics and clinical features, (b) The Short Form (SF-36) Health Survey, (c) The Beck Depression Inventory -I, and (d) The Cardiac Anxiety Questionnaire. There were no significant differences between the two genders with exception of marital status (p=0.010), dyslipidemia (p=0.050), grade of hypertension (p=0.014), cardiac left ventricular hypertrophy (p=0.004), renal failure (p=0.043) and stroke (p=0.024). Lower levels of quality of life and higher levels of depression and cardiophobia were observed compared to the general population. There were no significant differences on psychological measures between the two sexes (p>0.05). Cardiophobia was positively related to depressive symptomatology (r=0.533, p=0.000) while negatively to both physical and mental health summary measures of SF-36 health survey (r=-0.467, p=0.000 r=-0.537, p=0.000 respectively). Multiple linear regression models found that for psychical health depression and cardiac anxiety, avoidance activities had an influence on levels of quality of life in hypertensive patients, after controlling for age and other socio-demographic variables and clinical characteristics (Beta=-0.133, p=0.007, Beta=-0.364 p=0.000 and Beta=-0.167 p=0.006, respectively). For mental component summary depression and cardiophobia, heart focused attention had also impact on mental health in hypertensives (Beta=-0.438, p=0.016, Beta=-0.564, p=0.000 and Beta=-0.223, p=0.037, respectively) after adjustments. Heart focused anxiety symptoms-as avoidance activities and/or attention and monitoring cardiac activity, are related to hypertensive patients' present deteriorated depressive symptoms and levels of quality of life. Both depressive symptomatology and heart focused anxiety may be a mechanism partly responsible for hypertensive patients' present impaired levels of quality of life.

- Objectives: To evaluate the influence of titanium mesh on guided bone regeneration when used, either alone or in combination with autogenous bone block graft, in a canine ulnar model. Methods: Thirty-two, purpose bred, adult, castrated male Beagles were used, divided into four equal-size groups. A unilateral mid-diaphyseal ulnar critical-size defect was created in each dog. The ulnar segments were stabilized with a stainless-steel plate and screws. Each defect was managed by: no further treatment (Group A) or by placement of a bone block graft taken from the ipsilateral iliac crest (Group B), or titanium mesh wrapped around the ulna (Group C), or a bone block graft and titanium mesh (Group D). After six months, bone block biopsies were performed and the samples were scanned using micro-computed tomography. Qualitative histological evaluation was performed on two non-decalcified longitudinal sections from each block. Results: No significant differences in terms of mineralized bone volume were detected between the grafted sites (Groups B and D) or between the non-grafted ones (Groups A and C). The histological evaluation indicated good integration of the bone blocks irrespective of the use of titanium mesh. Clinical significance: The use of titanium mesh does not influence the amount of bone formation. The canine ulnar critical-size defect model seems to be a reliable model to use in experimental studies.
