Cell transplant-mediated tissue repair of the damaged spinal cord is being tested in several clinical trials. The current candidates are neural stem cells, stromal cells, and autologous Schwann cells (aSC). Due to their peripheral origin and limited penetration of astrocytic regions, aSC are transplanted intralesionally as compared to neural stem cells that are transplanted into intact spinal cord. Injections into either location can cause iatrogenic injury, and thus technical precision is important in the therapeutic risk-benefit equation...

Development of truly useful wearable physiologic monitoring devices for use in diabetes management is still in its infancy. From wearable activity monitors such as fitness trackers and smart watches to contact lenses measuring glucose levels in tears, we are just at the threshold of their coming use in medicine. Ultimately, such devices could help to improve the performance of sense-and-respond insulin pumps, illuminate the impact of physical activity on blood glucose levels, and improve patient safety. This is a summary of our experience attempting to use such devices to enhance continuous glucose monitoring-augmented insulin pump therapy...

There has been increasing use of a novel combined femoral venous sheath, catheter and retrievable self-expanding and collapsible diamond-shaped IVC filter (Angel® Catheter, BiO2 Medical), in severely injured patients who cannot receive anticoagulation. As the filter is not detached from the catheter/sheath, it should be easily retrieved. Outcomes included in large registries demonstrate a high safety profile and a 100% retrieval rate. However, at our institution-a Level 1 major UK trauma centre with 4 years of substantial experience in using this device-we've encountered three cases of device fracture and subsequent complicated retrieval dating from Dec 2016 to March 2017...

Background: Type 1 diabetes is a condition in which the pancreas produces little or no insulin. People with type 1 diabetes must manage their blood glucose levels by monitoring the amount of glucose in their blood and administering appropriate amounts of insulin via injection or an insulin pump. Continuous glucose monitoring may be beneficial compared to self-monitoring of blood glucose using a blood glucose meter. It provides insight into a person's blood glucose levels on a continuous basis, and can identify whether blood glucose levels are trending up or down...

Drowning contributes significantly to morbidity and mortality in the pediatric population but it is largely preventable through judicious use of safety measures. To affect outcomes surrounding drowning, pediatricians need to understand the most updated terminology, the basic resuscitation protocols, and the assessment and management of a drowning victim. Most importantly, pediatricians must appreciate the importance of properly counseling patients and families about drowning prevention. Effective preventive measures supported by the literature include constant and reliable adult supervision, swim instruction for most children older than age 4 years, pool isolation fencing, and the proper use of personal floatation devices...

Today IoT integrate thousands of inter networks and sensing devices e.g., vehicular networks, which are considered to be challenging due to its high speed and network dynamics. The goal of future vehicular networks is to improve road safety, promote commercial or infotainment products and to reduce the traffic accidents. All these applications are based on the information exchange among nodes, so not only reliable data delivery but also the authenticity and credibility of the data itself are prerequisite. To cope with the aforementioned problem, trust management come up as promising candidate to conduct node's transaction and interaction management, which requires distributed mobile nodes cooperation for achieving design goals...

The use of stem cell therapy in combination with a left ventricular assist device (LVAD) for patients with advanced heart failure (HF) is an attractive concept with the potential to alter the natural history of HF. Cell therapy trials for HF have demonstrated excellent safety and encouraging results, but current rates of myocardial recovery after LVAD implantation are limited. Early trials combining these 2 therapies to increase the likelihood of recovery and to potentially obviate the need for subsequent transplantation appear promising...

The trans-venous implantable cardioverter defibrillator (TV-ICD) is effective in treating life-threatening ventricular arrhythmia and reduces mortality in high-risk patients. However, there are significant short- and long-term complications that are associated with intravascular leads. These shortcomings are mostly relevant in young patients with long life expectancy and low risk of death from non-arrhythmic causes. Drawbacks of trans-venous leads recently led to the development of the entirely subcutaneous implantable cardioverter defibrillator (S-ICD)...
