A Review on Assisted Living Using Wearable Devices.

Forecasts about the aging trend of the world population agree on identifying increased life expectancy as a serious risk factor for the financial sustainability of social healthcare systems if not properly supported by innovative care management policies. Such policies should include the integration within traditional healthcare services of assistive technologies as tools for prolonging healthy and independent living at home, but also for introducing innovations in clinical practice such as long-term and remote health monitoring. For their part, solutions for active and assisted living have now reached a high degree of technological maturity, thanks to the considerable amount of research work carried out in recent years to develop highly reliable and energy-efficient wearable sensors capable of enabling the development of systems to monitor activity and physiological parameters over time, and in a minimally invasive manner.

Is the cost of the new home dialysis techniques still advantageous compared to in-center hemodialysis? An Italian single center analysis and comparison with experiences from western countries.

Introduction: Potential advantages of home dialysis remained a questionable issue. Three main factors have to be considered: the progressive reduction in the cost of consumables for in-Center hemodialysis (IC-HD), the widespread use of incremental Peritoneal Dialysis (PD), and the renewed interest in home hemodialysis (H-HD) in the pandemic era. Registries data on prevalence of dialysis modalities generally report widespread underemployment of home dialysis despite PD and H-HD could potentially provide clinical benefits, improve quality of life, and contrast the diffusion of new infection among immunocompromised patients.

Driver Drowsiness Detection: A Machine Learning Approach on Skin Conductance.

The majority of car accidents worldwide are caused by drowsy drivers. Therefore, it is important to be able to detect when a driver is starting to feel drowsy in order to warn them before a serious accident occurs. Sometimes, drivers are not aware of their own drowsiness, but changes in their body signals can indicate that they are getting tired.

Over the Limits of Traditional Sampling: Advantages and Issues of AICs for Measurement Instrumentation.

Data acquisition systems have shown the need of wideband spectrum monitoring for many years. This paper describes and discusses a recently proposed architecture aimed at acquiring efficiently wideband signals, named the Analog-to-Information Converter (AIC). AIC framework and working principle implementing the sub-Nyquist sampling are analyzed in general terms.

A Multicenter Study of IgE Sensitization to and Diet Recommendations.

[Trend in PD in non-pediatric public centers in Italy: results of the 2010 GSDP-SIN census and comparison with the 2008 and 2005 censuses].

The 2010 Italian Society of Nephrology Peritoneal Dialysis Study Group (GSPD-SIN) census (Cs-10) involved the 224 Centers performing PD in Italy. PD was used as 1st treatment in 23.3% (1429/4695) of pts (Cs-08:22.

A load volume suitable for reaching dialysis adequacy targets in anuric patients on 4-exchange CAPD.

Introduction: Continuous ambulatory peritoneal dialysis (CAPD) depuration indexes are targeted to get a minimum total weekly peritoneal urea clearance (Kt/V) of 1.70 and creatinine clearance/1.73 m(2) (pCrCL) of 50 l.

Peritoneal ultrafiltration in patients with advanced decompensated heart failure.

The aim of the Best Practice guidelines on peritoneal ultrafiltration (UF) in patients with treatment-resistant advanced decompensated heart failure (TR-AHDF) is to achieve a common approach to the management of decompensated heart failure in those situations in which all conventional treatment options have been unsuccessful, and to stimulate a closer cooperation between nephrologists and cardiologists. The standardization of the case series of different centers would allow a better definition of the results published in the literature, without which they are nothing more than anecdotes. TR-AHDF is characterized by the persistence of severe symptoms even when all possible pharmacological and surgical options have been exhausted.

The peritoneal dialysis catheter.

The results obtained from the positioning and management of the catheter for peritoneal dialysis depend on the techniques used, but also and above all, on the experience of the practitioners. A comparison between practitioners may help to change their convictions, as well as to further improve results, in the interests of patient welfare. This is the aim of these Best Practice Guidelines.

Peritoneal ultrafiltration in refractory heart failure: a cohort study.

Introduction: Acutely decompensated heart failure (HF) in patients with diuretic resistance is often treated with extracorporeal ultrafiltration. Peritoneal ultrafiltration (PUF) has been proposed for the long-term management of severe HF after resolution of the acute episode. The aim of the present study was to evaluate the use of PUF in the treatment of chronic refractory HF in patients without end-stage renal disease.

Surface integral formulations for the design of plasmonic nanostructures.

Numerical formulations based on surface integral equations (SIEs) provide an accurate and efficient framework for the solution of the electromagnetic scattering problem by three-dimensional plasmonic nanostructures in the frequency domain. In this paper, we present a unified description of SIE formulations with both singular and nonsingular kernel and we study their accuracy in solving the scattering problem by metallic nanoparticles with spherical and nonspherical shape. In fact, the accuracy of the numerical solution, especially in the near zone, is of great importance in the analysis and design of plasmonic nanostructures, whose operation critically depends on the manipulation of electromagnetic hot spots.

[Indications from the first audit on peritoneal dialysis in Piedmont and Aosta valley].

In March 2009 a clinical audit was held in Turin on peritoneal dialysis in order to analyze the problems that still hinder the effective deployment of the technique in Piedmont-Aosta Valley. Various data about epidemiological and clinical management were collected by means of a questionnaire that all 26 nephrology centers of the two regions responded to. The two major critical issues highlighted were the role of the outpatient facility dedicated to uremic patients and why the peritoneal technique was not chosen for new dialysis patients.

[Organohalogen contamination of a dialysis-water treatment plant].

On March 2001 the regular quality control test of the water used for dialysis in an urban centre using a reverse osmosis system revealed a high level of organo-halogenated contamination. The compounds implicated were: trichloroethylene (trielene) [M.Wt.

[Acute kidney failure caused by cholesterol atheroembolism].

Background: To describe the clinical aspects of renal failure due to cholesterol atheroembolism.

Methods: An hospital based observational study on renal failure due to cholesterol atheroembolism was carried out. Twenty-two cases (19 males, mean age 68 yrs, range 53-83 yrs) were identified from January 1992 to September 1998.

[Vascular access for chronic hemodialysis: current status and new directions in the Piedmont].

Long survival on dialysis and wide admissions of very old and high risk patients, have focused attention to the problem of vascular access in uremic patients. The situation is critical in the USA, where PTFE/bovine grafts are utilized in about 75% of the cases. conversely, AV fistulas are the main type of access in Piedmont, where their use approaches 90% of the cases, Cimino-Brescia fistulas account for 58% of vascular accesses versus 25% and 9% of proximal AV fistulas and PTFE/bovine grafts, respectively.

Are serum albumin and cholesterol reliable outcome markers in elderly dialysis patients?

Albumin and cholesterol are considered reliable outcome markers in dialysis patients; their influence, however, may also be related to non-independent factors, such as age and presence of co-morbid conditions. The aim of the study was an analysis of four outcome markers, assessed at start of dialysis: age, high risk conditions, cholesterol and albumin levels. Data were obtained from the Piedmont Dialysis and Transplantation Registry (northern Italy, about 4,400,000 inhabitants, 21 dialysis centres, open acceptance since mid-1970s, 5661 patients on file at 31 December 1992).

[Automated peritoneal dialysis (APD). Experience in 42 patients].

Automated peritoneal dialysis (APD) is currently considered as one of the most attractive home treatments for uremic patients. However, relevant costs and the presence of a dialysis machine prevent a wider diffusion of this technique. In this work we discuss the results obtained in 42 patients (12 females, 30 males) treated by two dialysis units of the Piedmont Region.

[The value of albumin and cholesterol blood levels as indicators of the risk of death in dialysis. Working Group of the Piedmont Registry of Dialysis and Transplantation].

In recent years, the availability of large epidemiological series allowed identification of biochemical outcome markers in the dialysis population. Interest towards albumin and cholesterol levels is motivated by their easy availability and by the presence of a strong short-term effect on mortality and morbidity. The aim of the study was an analysis of the relationship between albumin and cholesterol levels at start of dialysis and mortality (gross mortality and Kaplan Meier survival curves).

[Surgical interventions in dialysis patients in Piedmont: data from the Regional Registry. Working Group of the Piedmont Registry of Dialysis and Transplantation].

In this work surgical events in a large population of chronic dialysis patients are analysed. Data are obtained from the Regional (Piedmont) Registry of Dialysis and Transplantation (RPDT), that has collected information since 1981 about all chronic dialysis patients in the Region. Since 1984, causes of admission to-hospital are registered.

[Informatics support and teledialysis].

Computer-assisted medical activity is increasing in several fields, with wide perspectives in nephrology and dialysis accounting for the peculiar characteristics of this population such as number, complexity, follow-up length and economic costs. Since 1980 we have been studying a computerized organization of our Region's departments in order to achieve 3 main results: 1) a registry of all patients undergoing dialysis in the area, with a one- a-year complete clinical update; 2) a computerized medical chart, which could gather all the clinical, technical and managerial aspects of the treatment; 3) a teledialysis program, to follow every session in local and remote stations. The first aim has been reached with useful information for the dialytic policy in the area.

[Dialysis treatments outside the hospital].

In the early sixties a dramatic lack of hospital dialysis facilities prompted the development of home dialysis programs. The same reasons favoured in Turin, several years later, the start of a home-dialysis program and of the first European self dialysis program in an out-of-hospital setting. In the following years continuous ambulatory peritoneal dialysis was begun.
