Wearable and Noninvasive Device for Integral Congestive Heart Failure Management in the IoMT Paradigm.

Noninvasive remote monitoring of hemodynamic variables is essential in optimizing treatment opportunities and predicting rehospitalization in patients with congestive heart failure. The objective of this study is to develop a wearable bioimpedance-based device, which can provide continuous measurement of cardiac output and stroke volume, as well as other physiological parameters for a greater prognosis and prevention of congestive heart failure. The bioimpedance system, which is based on a robust and cost-effective measuring principle, was implemented in a CMOS application specific integrated circuit, and operates as the analog front-end of the device, which has been provided with a radio-frequency section for wireless communication.

EVAR with Aortic Placement of a Single JOTEC E-iliac Stent-graft System in a Patient with Poliomyelitis Aortoiliac Deformities.

Small-sized vessels can represent a contraindication to standard endovascular aortic repair (EVAR), and more specifically, aortoiliac deformities resulting from poliomyelitis may add an adjunctive challenge for total endovascular repair. Herein we report a case of a 62-year-old man with a 55 mm abdominal aortic aneurysm (AAA) and a history of poliomyelitis. More specifically, a computed tomography angiogram (CTA) showed a very narrow infrarenal aortic neck, measuring 13 mm in maximum diameter, and severely atrophic external iliac and common femoral arteries.

Early Renal Function Alterations in Renal Branches vs. Renal Fenestrations - A Dynamic Scintigraphy Based Prospective Study.

Objective: The objective of this prospective single centre study was to assess whether branches and fenestrations have different outcomes on renal function in the early phase.

Methods: From March 2018 to June 2019, 67 patients who underwent elective fenestrated and branched endovascular aneurysm repair (F/BEVAR) procedures were enrolled in this study. The patients were divided into two groups according to the renal bridging component configuration (fenestration vs.

Late failure of a Nellix endoprosthesis treated with the t-Branch off-the-shelf multibranched stent graft.

A 66-year-old man arrived at our emergency department 3 years after an endovascular aneurysm sealing procedure performed at another center. Computed tomography angiography showed distal migration of a Nellix endoprosthesis (Endologix, Irvine, Calif) and a posterior contained rupture. The left kidney was excluded by an occluded iliac-left renal bypass, which was performed at the time of the Nellix implantation because of unintended coverage.

The "Destino-guided BEVAR" to Catheterize Downward Branches from a Femoral Access: Technical Note and Case Report.

Background: The aim of this study is to report the Destino-guided branched endovascular aortic repair approach as a valid alternative to catheterization downward branches in complex aortic arch/descending thoracic anatomies.

Methods & Results: A 53-year-old woman with Marfan syndrome underwent a thoracoabdominal aortic aneurysm (TAAA) repair for a type III dissecting aneurysm. A custom repair with an endograft having 3 fenestrations (for renal arteries and superior mesenteric artery) and 1 branch for the celiac trunk was planned.

Global Post-Market Clinical Follow-up of the Treovance Stent-Graft for Endovascular Aneurysm Repair: One-Year Results From the RATIONALE Registry.

Purpose:: To evaluate the safety and performance of the Treovance stent-graft.

Methods:: The global, multicenter RATIONALE registry ( ClinicalTrials.gov; identifier NCT03449875) prospectively enrolled 202 patients (mean age 73.

A wireless multi-channel bioimpedance measurement system for personalized healthcare and lifestyle.

Miniaturized, noninvasive, wearable sensors constitute a fundamental prerequisite for pervasive, predictive, and preventive healthcare systems. In this sense, this paper presents the design, realization, and evaluation of a wireless multi-channel measurement system based on a cost-effective high-performance integrated circuit for electrical bioimpedance (EBI) measurements in the frequency range from 1 kHz to 1 MHz. The resulting on-chip spectrometer provides high measuring EBI capabilities and together with a low-cost, commercially available radio frequency transceiver device.

[Burden of caregivers of aged patients at a hospital acute care unit and role of the psychologist in the management of the "fragile" caregiver].

Introduction: the purpose was to investigate and describe the subjective burden perceived by caregivers of elderly patients affected by multiple pathologies admitted to an acute ward and to consider the necessity of intervention with special reference to the analysis of psychological support need.

Methods: a sample of 100 caregivers of elderly patients admitted to Geriatrics ward was interviewed using two instruments assessing care burden: the Family Strain Questionnaire--Short Form (FSQ-SF) and the Anxiety and Depression Short Scale (AD-R).

Results: the FSQ-SF highlighted that 7% of caregivers showed adequate coping abilities to face the stress related to illness; 21% of caregivers could require psychological counselling intervention; for 48% an intervention of psychological evaluation and support was recommended; for 24% the psychological intervention became urgent.

The subjective feeling of burden in caregivers of elderly with dementia: how to intervene?

The aim of this study was to know how caregiver burden was influenced by caregivers' and patients' characteristics and by social support; the intention was to use these elements in order to suggest how to optimize the interventions which may reduce caregivers' subjective feeling of burden. A sample of 99 caregivers was studied using a descriptive-correlational design. Caregiver burden was assessed by using the caregiver burden inventory (CBI).

Left ventricular function, cardiac dysrhythmias, atrial activation, and volumes in nondipper hypertensive individuals with left ventricular hypertrophy.

Background: Arrhythmic patterns and left ventricular geometric adaptations to pressure overload were investigated in 76 patients with untreated borderline-to-moderate sustained essential hypertension studied by 2-dimensional and M-mode echocardiography, 12-lead, Holter, and signal-averaged electrocardiography, and ambulatory blood pressure monitoring.

Methods And Results: Sixty-two age- and sex-matched normal adults were chosen for data comparison. Hypertrophic hypertensive patients were subdivided into 2 subgroups: 44 patients with nocturnal blood pressure reduction (dippers) and 32 patients without it (nondippers).

Spectral analysis of heart rate variability in elderly non-dipper hypertensive patients.

To assess by autoregressive model the frequency domain heart rate variability (HRV) during clinostatism and after passive orthostatic load (head-up tilt), 81 hypertensive and normotensive subjects (42 men and 39 women) were subdivided into four groups: 20 adult normotensive subjects (Group 1); 21 elderly normotensive subjects (Group 2); 20 elderly hypertensive subjects with nocturnal blood pressure (BP) falls (Group 3); and 20 elderly hypertensive subjects without nocturnal BP falls (Group 4). They were chosen to assess the influence of aging and arterial hypertension on sympathetic-parasympathetic balance. The age-related decrease observed in nearly all HRV spectral frequency components (normalised units [NUs], high frequency [HF] and low frequency [LF]) was reported in elderly patients in rest conditions.

White-coat hypertension and cardiac organ damage in elderly subjects.

Purpose: The aim of this study was comparing the cardiac mass in elderly normotensive subjects and elderly white-coat hypertensive patients by examining in perspective, in consecutive patients, office blood pressure (BP), ambulatory BP, and echocardiographically determined left ventricular mass.

Patients And Methods: We studied 42 elderly patients attending a hypertension unit: of these, 22 (mean age 68.7 +/- 3.
