Exploiting system fluctuations. Differential training in physical prevention and rehabilitation programs for health and exercise

2010

Background. Traditional causal modeling of health interventions tends to be linear in nature and lacks multidisciplinarity. Consequently, strategies for exercise prescription in health maintenance are typically group based and focused on the role of a common optimal health status template toward which all individuals should aspire. Materials and methods. In this paper, we discuss inherent weaknesses of traditional methods and introduce an approach exercise training based on neurobiological system variability. The significance of neurobiological system variability in differential learning and training was highlighted. Results. Our theoretical analysis revealed differential training as a meth…

Minor hepatic resection for hepatocellular carcinoma in cirrhotic patients: Kelly clamp crushing resection versus heat coagulative necrosis with bipo…

2011

Hemorrhage and postoperative liver insufficiency are frequent and serious complications of hepatic resection in cirrhotic patients. The aim of this study was to assess retrospectively whether the surgical techniques using Kelly clamp crushing resection or heat coagulative necrosis with a bipolar radiofrequency device can reduce the incidence of the above complications and an eventual recurrence of neoplasia on the liver slice. We retrospectively reviewed the results of 35 patients who had undergone resection for monofocal hepatocellular carcinoma at our center. Thirteen patients (Group A) had undergone liver resection with Kelly clamp crushing resection, 22 patients (Group B) had had liver…

Cochlear implant complications and failures

2010

Abstract Introduction Cochlear implantation is a relatively safe surgery performed on profound bilateral hearing loss patients. Its surgical indications have increased and the age of implantation has decreased over the last years. As with any other surgery, it presents complications; device failure is one of the most important, given its potential risk for the need to explant and reimplant the device. Objective To evaluate cochlear implant complications, determine possible causes and discuss medical and surgical management. Material and methods A retrospective study of cochlear implants was performed. A total of 246 implants over an eleven-year period were evaluated. The sample consisted of…

Validation of a novel contact-free heart and respiratory rate monitor.

2021

There is a growing need for remote monitoring of patients due to a lack of resources and infection control. Current systems use sensors that require constant physical contact with the user, which may result in discomfort or lack of adherence. In the present study, we evaluated the accuracy of a new contact-free system to monitor heart and respiratory rate. Study participants were measured simultaneously using two devices: a contact-free optical system that measures nano-vibrations and movements (investigational device, "Gili Pro BioSensor") and a standard reference bed-side monitor, inclusive of an electrocardiogram and capnograph modules (Mindray

Effect of Repetition and Inspection Times on Picture Recall in Patients with Dementia of Alzheimer Type

1997

The present study is part of a series of systematic studies intended to identify simple strategies of picture presentation to improve recall performance in demented subjects. The aims of this design were to examine the effects of elaboration by naming, 4-fold repetition and different inspection times on memory performance. 19 patients with senile dementia of Alzheimer type and 21 control subjects with remitted depression were included. Picture recall was examined using different presentation conditions on 5 consecutive days. The presentation conditions significantly influenced recall performance depending on the diagnosis and on the delay of recall. Naming of pictures did not improve later …

Mid-Term Results of Endovascular Aneurysm Sealing in the Treatment of Abdominal Aortic Aneurysm With Unfavorable Morphology.

2020

Purpose: To report mid-term results of endovascular aneurysm sealing (EVAS) of abdominal aortic aneurysms (AAA) deemed unsuitable for a standard endovascular aneurysm repair (EVAR). Methods: A prospectively maintained database of 42 patients with EVAR-unfavorable anatomy treated by EVAS combined with chimney grafts in case of the proximal AAA neck shorter than 5 mm was analyzed. Early outcomes included final angiographic result, intra- and early post-operative deaths, and complications. Mid-term outcomes included all-cause mortality (ACM), aneurysm-related mortality (ARM), patency of the stents, occurrence of endoleaks, serious complications and graft failures defined as the AAA growth of m…

IMPROVEMENT OF PICTURE RECALL BY REPETITION IN PATIENTS WITH DEMENTIA OF ALZHEIMER TYPE

1997

The evidence for positive effects of repetition on recall performance in patients with dementia of Alzheimer type is equivocal. This may be due to the difference repetition conditions used. The aim of this study was therefore to evaluate the effects of different repetition modes on the improvement of recall performance in demented subjects. Twenty-four patients with Alzheimer type dementia and 24 control subjects with remitted depression were included in the study. Pictures were presented repeatedly using different presentation modes at a constant total presentation time. Free recall was tested repeatedly after different periods of delay (0-8 hours). Immediate and delayed list repetition si…

Media devices in pre-school children: the recommendations of the Italian pediatric society

2018

Abstract Background Young children are too often exposed to mobile devices (MD) and most of them had their own device. The adverse effects of a early and prolonged exposure to digital technology on pre-school children has been described by several studies. Aim of the study is to analyze the consequences of MD exposure in pre-school children. Methods We analyzed the documented effects of media exposure on children’s mental and physical health. Results According to recent studies, MD may interfere with learning, children development, well being, sleep, sight, listening, caregiver-child relationship. Discussion Pediatricians should be aware of both the beneficial and side effects of MD and giv…

Late postoperative opacification of MemoryLens hydrophilic acrylic intraocular lenses Case series and review

2003

Abstract Purpose: To report clinical and spectrographic analyses of 2 explanted hydrophilic acrylic intraocular lenses (IOLs). Setting: John A. Moran Eye Center, Salt Lake City, Utah, USA, and Johannes Gutenberg-University, Department of Ophthalmology, Mainz, Germany. Methods: We report 6 cases of opacification of MemoryLens ® IOLs (Ciba Vision) that occurred approximately 2 years after implantation. The anterior and posterior surfaces of the IOLs had a white, frosted appearance, and the IOLs' interior looked brown, similar to the appearance of a brunescent cataract. Two of the IOLs were explanted because of a significant decrease in visual acuity. The IOLs were sent for further clinicopath…
