The proposed system describes the standardized effects of “Remote Patient Disease Diagnosing and Treatment prototype”, a system developed to facilitate the population living in remote areas with focus on third world countries. Where availability of health facilities/services are limited or not available. Utilizing the customized sophisticated medical equipments and combining the high speed data communication...
By analyzing the factors which have impact on how the hospital arrange its sickbeds, this paper gives a evaluation index system about arranging the sickbeds and a evaluation model that based on the overall satisfaction of the patients and the hospital. From the perspective of patients, we consider their time, cost and the therapeutic effect, while from the viewpoint of the hospital, the analysis incorporates...
Colorectal cancer is the third most common cancer. Depending on the extent of the disease, radiotherapy and surgery are currently the only curative therapies. When surgery is performed, the shortest distance from affected regions to the resection boundary is an important predictive factor for prognosis of the disease. This article will present segmentation of the rectal wall in macroscopic slices...
As with all surgical procedures, implantation comes with the added risk of infection. The inability of antibacterial therapy to treat persistent infection demonstrates the need for a more advanced therapeutic approach. The goal of this proposal is, for the first time, to use superparamagnetic iron oxide nanoparticles (SPION) to treat infection on biomedical devices. The hypothesis of this study is...
Bone loss in the spine due to estrogen withdrawal following menopause leads to reduced mechanical strength and ultimately fracture in women. Ovariectomized mice may serve as an appropriate model for Type II osteoporosis, but have not been fully characterized. This study relates whole bone mechanical properties to morphological changes in mouse vertebrae following estrogen withdrawal. The development...
Pre-surgical planning of mitral valve (MV) repair in patients with Barlow's disease (BD) and fibroelastic deficiency (FED) is challenging due to inability to accurately assess the complexity of MV prolapse. We hypothesized that the etiology of degenerative MV disease (DMVD) could be objectively and accurately determined using morphologic analysis of MV geometry from real-time 3D echocardiographic...
Optical diseases like retinitis pigmentosa and glaucoma (among others) are the main cause of partial or total blindness in humans. These diseases are typically treated by allopathic medicine and visual surgery. Recent studies show that partial recovery of sight can be produced by electrical stimulation. Most of the equipment used in these stimulation therapies only allows the generation of a single...
The HHT (Hilbert-Huang Transform) method is adopted to decompose the pulse signals synchronously from the carotid and wrist arteries both in healthy people and those patients suffering from coronary heart disease into the different mode orders. Based on the cross-correlation analysis, it is statistically found that quasi-cycles of 2nd-modes from healthy objects correspond respectively to 1/3 of their...
Stanford type B aortic dissections (TB-AD), which split the descending aorta in a true and false lumen, have better in-hospital survival than type A dissections affecting the ascending aorta. However, short-term and long-term prognosis for the individual patient remains challenging, with one in four patients not surviving after 3 years. Towards a better understanding of the influence of tear location...
Deep brain stimulation is an increasingly prevalent surgical option in the treatment of a multitude of neurological conditions, most notably Parkinson's disease. The development of a neurofeedback device is driven primarily by stimulator habituation, surgical risk factors, the cost of battery replacement, and reported neuropsychiatric side-effects under prolonged chronic administration. Here we present...
Although atrial fibrillation (AF) is a common complication of cardiac surgery, its pathophysiology remains unclear. The study of post-operative AF demands for the recording of cardiac electrical activity in correspondence of AF onset and progression. Long-term recordings in post-surgery patients could provide this information, but, to date, have been limited to surface signals, which precludes a characterization...
An implanted vestibular neurostimulator has been developed based on commercial cochlear implant technology. It has been implanted chronically in Rhesus monkeys and the physiology of electrical stimulation of the vestibular periphery has been studied. We are currently proposing a human feasibility study of implantation of the device for the treatment of incapacitating Meniere's disease. Because no...
When recovery of the cardiac function is detected in assisted hearts, the ventricular assist device can be removed. Due to the invasiveness of the surgical procedure, an accurate assessment of cardiac function is fundamental for the treatment success. The main challenge for the detection of cardiac function during assistance is to know whether the cardiac function index represents the cardiac function...
Percutaneous nephrolithotomy (PCNL) for the treatment of renal stones and other related renal diseases has proved its efficacy and has stood the test of time compared with open surgical methods and extracorporeal shock wave lithotripsy. However, access to the collecting system of the kidney is not easy because the available intra-operative image modalities only provide a two dimensional view of the...
This study is aimed to investigate the muscle activity changes, including fatigue effects and the symmetry of muscle activation between affected and unaffected sides during a 10-day body weight support treadmill training program using a focal ischemia rat hindlimb model. Our findings of the MPF drop after stroke might indicate fatigue effects due to the compensation loading share of the ipsilateral...
This study evaluated the long-term effects of deep brain stimulation of the subthalamic nucleus (DBS-STN) on gait initiation. Six Parkinson's disease (PD) patients who had undergone DBS-STN and 31 control subjects were evaluated. PD subjects were assessed at two different time periods: 11.3 ± 10.3 (P1) and 78.9 ± 10.6 (P2) months after surgery. Subjects under stimulation were tested in two conditions:...
The aim of this study is to evaluate the Pulmonary Rehabilitation (PR) and post-operative complications on lung cancer patients by means of opto-electronic plethysmography (OEP). FEV1 and FVC have been measured through OEP on 13 lung cancer patients, before and after lobectomy and after pulmonary rehabilitation (PR). In every patient, FEV1 decreases after surgery, whereas FVC decreases only in 8 patients...
Deep Brain Stimulation (DBS) is an effective surgical therapy for the treatment of movement disorders in Parkinson's disease (PD) and other neurological pathologies. DBS is known to modulate the spiking activity of the neurons within the basal ganglia, but how such modulation impacts the primary sensorimotor cortex is still uncertain. In this study a monkey was stimulated with DBS at several frequencies...
Heart diseases such as angina pectoris and myocardial infarction have been becoming the leading causes of death all over the world in recent years. The pharmacotherapy and the surgical operations have been executed for treating heart problems. The percutaneous coronary intervention (PCI) with catheter is frequently used for the treatment of coronary artery diseases, but the treatment of chronic total...
Mid-infrared (MIR) laser with a specific wavelength can excite the corresponding biomolecular site to regulate chemical, thermal and mechanical interactions to biological molecules and tissues. In laser surgery and medicine, tunable MIR laser irradiation can realize the selective and less-invasive treatments and the special diagnosis by vibrational spectroscopic information. This paper showed a novel...
