Light therapy comes in a variety of ways, ranging from being exposed to daylight, to being exposed to light emitted by light boxes and ambient bright light. Light therapy is an area in medicine where medical sciences meet the realms of physics, engineering and technology. Therefore, it is paramount that attention is paid in the methodology of studies to the technical aspects in their full breadth. This paper provides an extensive introduction for non-technical researchers on how to describe and adjust their met...

Our results suggest that enterococci play a role in the severity of postoperative complications. In particular, detection of enterococci in patients with anastomotic leakage are suggested to be an indicator of severe illness. We found significantly higher rates of E. faecium than described before, but no significant differences in clinical outcome between E. faecalis and E. faecium. When empirical therapy against enterococci is recommended, E. faecalis and E. faecium should both be covered.

The threshold for clinically relevant malrotation has been established to be in the region of 15° whereas the incidence of significant malrotation following femoral nailing ranges from 22 to 43 percent. Many studies have been performed to address this issue with the major challenge acknowledged to be intraoperative control of femoral anteversion. In the current study, the investigators developed and analysed a novel method to estimate the femoral antetorsion based on computed tomography (CT) data. They hypothesized that this method would be intra-operatively feasible and repeatable ...

The only valid, objective monitoring method is computer tomography-assisted torsion measurement between the proximal and distal femur; unfortunately, this can only be carried out postoperatively. A difference of 15° compared to the contralateral femur is seen as an indication for revision. With the development of computer-assisted surgery, new possibilities for performing torsion control and correction intraoperatively has been introduced. These methods also allow for navigation-assisted definition of the optimal incision site, intramedullary access, femoral nail and interlocking. The ...

It involves the development of simulation models that portray process flows and feedback that may be tested to find effective designs to overcome ineffective means of healthcare delivery. An urban county hospital (UCH) in Minnesota, USA is used to demonstrate a modular system dynamics modeling approach to simulate and optimize internal patient and process flow where major costs are also considered. This allows decision makers to visualize overall efficiencies through optimal bed capacity for peak patient flow of emergency and routine patients in a large healthcare delivery operati...

Samples were taken on day 0, 7 and 14. Decellularized tendons were chosen as a negative control. Cell quantity was measured by the MTS-Test. Histology was analyzed by Haematoxylin-Eosin- and Pentachrome-coulouring. The cultivated tendons were tested biomechanically compared with the decellularized control group. MTS-Test revealed an increase of cell count of 7% in the static group and a decrease of 9% in the perfusion group. The perfusion group showed a stronger network of the fibroblasts and a higher amount of produced extracellular matrix. Biomechanical testing revealed significantly higher stability in the decellularized control group. This trial shows up new po...

Thus, quantitative assessment of bone healing after fracture becomes important. In this paper, we present a mathematical model which describes the interaction of a pulsed mode ultrasound waves with a multilayered biological structure. The model is applied to estimate the bone callus thickness and degree of hardness. Different frequencies are utilized to obtain highest measurement sensitivity and accuracy of callus thickness and degree of hardness. It is found that a transducer operating at 1 MHz has the highest sensitivity to the different phases of callus hardening. On...

Sensors are the fundamental physical layer with any smart home, as the data they generate is used to inform decision support systems, facilitating appropriate actuator actions. Positioning of sensors is therefore a fundamental characteristic of a smart home. Contemporary smart home sensor distribution is aligned to either a) a total coverage approach; b) a human assessment approach. These methods for sensor arrangement are not data driven strategies, are unempirical and frequently irrational.

The study involved 16 randomly selected male patients undergoing peripheral reconstructive surgery. Blood samples were drawn and analyzed in the operating room on the Sonoclot Coagulation and Platelet Function Analyzer. Results showed that patients respond to heparin differently. The Sonoclot monitors the hemodynamics of blood using four variables: SonACT (activated clotting time) time, rate, peak, and contraction rate. Heparin has three effective on the Sonoclot Signature; prolonged ACT result, lower clot rate, and reduction in clot retraction. The SonACT time is the time for first fibrin to form. Prolong this time indicates the presence of anticoagulation. The Sonoclot Analyzer res...

In tissue engineering bioreactors can be used to aid in the in vitro development of new tissue by providing biochemical and physical regulatory signals to cells and encouraging them to undergo differentiation and/or to produce extracellular matrix prior to in vivo implantation. This chapter discusses the necessity for bioreactors in tissue engineering, the numerous types of bioreactor that exist, the means by which they stimulate cells and how their functionality is governed by the requirements of the specific tissue being engineered and the cell type undergoing stimulation.

They have found application in medicine due to the large amounts of data (e.g. laboratory measurements such as blood pressure, heart rate, body-mass index) and information (e.g. patient history, population statistics based on age and sex) that must be considered before diagnosing any disease or recommending a therapy. A well known example is the embedded software in defibrillators which allows a 'shock' to be delivered, by analyzing the electrocardiogram for known conditions (heart attack). The shock can restart the heart and timely delivery can resuscitate the patient. As well as assisting in primary diagnosis, ...

The body can be considered as a chemical and electrical system supported by a mechanical structure. Measuring and quantifying such electrical activity provides a means for objective examination of heath status. The term electrogram, from the Greek electro meaning electricity and gram meaning write or record, is the broad definition given to the recording of electrical signal from the body. In order that comparisons of electrical activity can be made against normative data, certain methods and procedures have been defined for different electrograms. This paper reviews these methods and procedures for the ...

Flow experiments were performed by connecting the climate chamber to an airflow generator via a flow chamber with cultured NEC. Experiments at two controlled climate conditions, 25 degrees C and 40% relative humidity (RH) and 37 degrees C and 80%RH, were conducted to study mucin secretion from the cultures inresponse to the flow. The new climate chamber is a relatively simple and inexpensive apparatus which can easily be connected to any flow system for climate controlled flow experiments.

In recent years, several techniques to modify the implant surface to increase bone formation around implants have been described by many authors. Most endoprostheses used in orthopaedic surgery are manufactured from titanium. To understand the process of osseointegration, one has to take into account, that the adhesion of plasma proteins on the surface of titanium implants plays an essential role in the process of implant integration. In the last years, several modifications of implant surfaces (structure, chemistry, surface charge, wettability) have been investigated to improve osseointegration of titanium implants.

This includes awareness of the safety issues regarding equipment, particular when it is an electrically powered device. Incidents can occur in the clinic in which a medical device is suspected of contributing to patient or staff injury. It is important that one can identify in advance any potential hazards which may arise with electrical equipment due to technical or environmental factors.

These may lead to severe postoperative sequelae such as additional correctional operations and difficult rehabilitation. Insufficient visualization can be considered the main reason for these complications. Finally, retention of the fragments in the correct alignment before nail insertion is difficult.

In order to monitor the functional health of smart home residents, we need to design technologies that recognize and track the activities that people perform at home. Machine learning techniques can perform this task, but the software algorithms rely upon large amounts of sample data that is correctly labeled with the corresponding activity. Labeling, or annotating, sensor data with the corresponding activity can be time consuming, may require input from the smart home resident, and is often inaccurate. Therefore, in this pap...

Our approach involves high level modeling of daily activities of the elderly by breaking down these activities into smaller units, which can then be automatically recognized at a low level by collections of sensors placed in the homes of the elderly. This separation allows us to employ plan recognition algorithms and systems at a high level, while developing stand-alone activity recognition algorithms and systems at a low level. It also allows the mixing and matching of multi-modality sensors of various kinds that go to support the same high level requirement.Currently our plan recognition algorithms...

However, there is significant effort involved in installing the hardware necessary to monitor the movements of an elder throughout an environment. Our work seeks to address the high infrastructure requirements of traditional location-based smart home systems by developing an extremely low infrastructure localisation technique.

A similar dissociation between acuity and hyperacuity has been shown to be present in strabismic but not in anisometropic amblyopia, thus leading to the suggestion that the strabismic fovea is similar to the normal periphery. Here it is shown that a quantitative model for spatial pattern discrimination, which accounts for foveal hyperacuity data, can be extended to encompass both the periphery and amblyopia if appropriate alterations are made. For the periphery it is necessary to increase the size of model receptive fields and to introduce both spatial undersampling and position irregularity (i.e. irregularity in the location of cortical filters).

Intraoperative measurement of rotation remains difficult, and multiple techniques have been described to address this. Regardless of the method used, rotational toggling may occur between the interlocking screws and the screw holes. We hypothesized that a clinically significant amount of rotation may occur with standard statically locked intramedullary nails. Mid-shaft diaphyseal fractures were created in 24 cadaveric femurs. Specimens were divided into 4 groups, and were stabilized with a statically locked intramedullary nail, a dynam...

Osteocytes are the most abundant cells in bone, and their death by microdamage has been suggested to be the major event leading in the initiation of osteoclastic bone resorption. Even though there is increasing evidence that osteocyte density, microcracks and targeted remodeling are related, there still exist several questions. For example, how osteoclasts are targeted to the specific site of microdamage for repair. It has been proposed that apoptotic osteocytes could secrete a specific signal to target osteoclasts. The other question is the nature of this signal. To elucidate the role of microdamage-induced osteocyte cell death in t...

This intriguing possibility provides a novel paradigm for understanding previously reported osteogenic benefits of low amplitude dynamic loading. However, it is unknown whether bone cell mechanosensitivity is enhanced by noise as an alternative mechanism for an amplified response to small stresses. We studied whether noise of varying intensities enhanced the mechanosensitivity of MC3T3-E1 cells. Nitric oxide (NO) production was measured as the parameter for bone cell activation. Dynamic fluid shear stress stimulated bone cells provided an initial-stress kick was implemented. Without the initial ...

It protects vital organs, regulates calcium levels and allows mobility. As a result of daily activities, bones are cyclically strained causing microdamage. This damage, in the form of numerous microcracks, can cause bones to fracture and therefore poses a threat to mechanical integrity. Bone is able to repair the microcracks through a process called remodelling which is tightly regulated by bone forming and resorbing cells. However, the manner by which microcracks are detected, and repair initiated, has not been elucidated until now. Here we show that microcrack accumulation causes damage to the network of cellular processes, resulting in the release of RANKL ...

The device was tested in a bone-defect model with different test-specimens chosen to simulate the stiffness of bone at different stages of healing. To verify the results, it was tested in an animal fracture study in rabbits during the healing period with and without an intramedulary implant.

Patients with impaired motosensory capacities are at high risk of developing DTI. There is a critical medical need for developing risk assessment tools for DTI. A new anatomical index, the Compression Intensity Index: CII=(BW/Rt);{1/2}, which depends on the body weight (BW), radius of curvature of the ischial tuberosities (R) and thickness of the underlying gluteus muscles (t), is suggested for approximating the loading intensity in muscle tissue during sitting in permanent wheelchair users, as part of a clinically-oriented risk assessment for DTI.

The model predicts the accumulated percentage of broken trabeculae delta in a vertebral region of interest (ROI) over 60 years, by employing Euler's theory for elastic buckling. The accumulated failure delta is calculated as function of the daily activity characteristics and rate of annual bone loss (RABL) with aging. An RABL of unity represents the normal bone loss attributed to aging per se, whereas RABL>1 is assumed to represent pathological bone metabolism such as osteoporosis. Simulations were conducted for a range of RABLs, to determine the effect of changes in bone metabolism on the accumulat...
