Medical World is dedicated to providing information about topics in the medical science and medical technology sector. 

A better health for all is a growing problem in the world, particularly in poorer countries. Medical research and health research therefore is also responsible for global health care. 
Health research can well-aimed contribute to significantly improve medical care. 

Due to technological developments and increasing knowledge modern medical research is becoming increasingly complex. For this reason, researchers increasingly bundle their knowledge and medical discoveries into larger consortia with partners from different countries. Collaboration often goes beyond Europe and includes countries such as Canada, the USA and others. Their common goal is to improve the medical technology to improve the treatment options for all patients. 

Medical World provides you with news on medicine with up-to-date articles on studies and discoveries in the field of medicine and medicine technology.

Reducing Opioid Use by Spinal Cord Stimulation

According to a new study, most patients took fewer pain medication after the implantation of a spinal cord Stimulation device. In this study funded by St. Jude Medical their Prodigy Spinal Cord Stimulation System showed that it is effective in treating chronic pain. After receiving the spinal cord stimulation device, the opioid use remained stable or was less than before.

 

The results lead the researchers to suggest spinal cord stimulation (SCS) to be preferred by physicians over more painkiller prescription for patients whose pain over time got worse. Obstructing pain messages traveling from the nerves to the brain, the small battery-powered transmitters provide signals through electrical wire implanted beside the spinal cord.

The opioid use from 5476 patients with SCS were compared to before and after implantation of the device. One year after implant, the study showed that of the patients continuing SCS therapy, 93% had lower everyday morphine-equivalent doses compared to patients who had their SCS device removed.

 

Principal researcher and neurosurgeon Ashwini Sharan, stated that patients had an enormous increase in their narcotic use one year before the implant. With the persons continuing with the SCS the dose decreased again afterwards tot the level of before the medication rise.

 

Unbelievable as it is, the relationship between pain relief narcotics and the implants has never been studied before. The researchers were unaware of which manufacturers’ SCS devices had been implanted in the patients. No funding is provided for further study

 

According to Sharan, Spinal Cord Stimulation is the last hope because after almost doubling the narcotic dosage within one year, the detachment off this dose takes much lost time.

The cost of a one year morphine prescription is normally $5,000 to which the costs of the side effects have to be added. A spinal cord stimulator averagely cost up to 4 times as much in 2015, depending on the model.

 

Hospitals tend to choose using the newer models and Sharan says to implant around 300 devices per year, including SCS. According to him he tries to emphasize the distinction between features and function of a device when addressing physicians.

 

 

The Multi-particulate Delivery System Sympfiny

For the design of Sympfiny, a multi-particulate medicine delivery system for children the company HS Design was subsidized with 50000 $.

 

Every parent knows that administering medicine to children can be very difficult. The main problem is the awful taste of most medicine. In order to solve the taste problem HS Design offers a high-tech solution with its Sympfiny Design.

 

The Sympfiny multi-particulate drug system, delivers medicine not in liquid form but as solid coated microspheres, dissolving in the stomach. In this manner children do not having to deal with the bad taste. The solid drug form offers other problems however. The drug particles can stick together when damp or static, or when being dry some part of the particles can escape through small openings in a pack or satchel. This can lead to inaccurate dose delivery.

 

Using the same technique for multi-particulate dry powder as for liquid oral medicine, Sympfiny is the new drug-delivery solution. According to Michael Quinn, director of engineering at HS Design, the design of the Sympfiny device is based on the ‘syringe and bottle’ format. The protective bottle stores the multi-particles and the syringe is for dosing.

 

Solid multi-particulate drugs are also more easy to deliver to children in rural or remote settings in developing countries. The multi-particulate formulation makes medication more easy to store and no water is required for administering the drugs.

 

After Pfizer and the Institute for Pediatric Innovation worked together in creating the new solid drug formulation technology, it required a different drug delivery system to ensure accurate dosing. The Sympfiny dispensing device was designed ensuring usability, accuracy, and protection of the drug.

 

At BIOMEDevice Boston, the largest medtech event in New England, the delivery device was selected as one of two winners by Innovation Prize Tour participants. During an open challenge from the Institute of Pediatric Innovation and Pfizer the HS dispensing device design won a $ 50,000 grant.

Less Radiation for Cancer Patient by Using New MR-Linac Device

  

Friday the 19. May the first patient was treated using the high-field MR-guided linear accelerator (MR-Linac) at the University Medical Center (UMC) in Utrecht/Netherlands. This latest radiotherapy device provide accurate and actual visual images enabling precise irradiation with minimal damage to surrounding tissue even in case of a moving tumor while treating.

 

This MR-Linac system, installed by Elektra and Royal Philips, is emerging as a promising appliance in the field of oncology, for locating and quantifying the tumor tissue, for planning the appropriate therapy, for treatment guidance and therapy evaluation.

 

According to The Netherlands Cancer Institute, precise and correct dose of radiation is potentially reducing side effects of radiation sessions and improves the quality of life, and ultimately regulating the radiation dose increases tumor control ability. 

 

By combining a MRI device and a radiation device, cancer patients would need less radiation because of the greater effectiveness of the radiation. A further great advantage is that less healthy surrounding tissue is affected by the radiation.

 

The new device, developed by some Utrecht professors, is currently being tested on people for the first time, after its development period of 18 years.  Groundbreaking the experts call this new device and it is expected to be used in hospitals and cancer centers and clinics on a word-wide scale in future.  Showing crystal clear images during the treatment, the device can accurately irradiate the tumor, even when moving while the patient is breathing for instance. In this way the treatment can be adjusted to the patient while being in the device. The irradiation times can be lowered so the patient does not have to spend so much time at the hospital.

 The experimental irradiation method is currently applied to five patients with bone tumors. When this radiation turns out to be successful, patients with tumors in the abdomen or pelvis are next to receive the treatment.
