Jungok Kim, Ji-Young Lee, Haejeong Lee, Ji Young Choi, Dae Hun Kim, Yu Mi Wi, Kyong Ran Peck, Kwan Soo Ko
We investigated the genetic background and microbiological features of T6SS-positive Acinetobacter baumannii isolates and clinical impact of the T6SS in patients with A. baumannii bacteremia. One hundred and sixty-two A. baumannii isolates from patients with bacteremia in two tertiary-care hospitals in Korea were included in this study. Approximately one-third (51/162, 31.5%) of the A. baumannii clinical isolates possessed the hcp gene, and the hcp-positive isolates were found in several genotypes in multilocus sequence typing...

H Sahinbas, M Rosch, M Demiray
Hyperthermia has been shown to be a medically useful procedure applicable for different indications. For the connection between clinical effects and heat, it is important to understand the actual temperatures achieved in the tissue. There are limited temperature data available when using capacitive hyperthermia devices even though this is worldwide the most widespread method for loco-regional heating. Hence, this study examines temperature measurements using capacitive heating. Bioequivalent phantoms were used for the measurements, which, however, do not consider perfusion in live tissue...

Electronic devices placed in the gastrointestinal (GI) tract for prolonged periods have the potential to transform clinical evaluation and treatment. One challenge to the deployment of such gastroresident electronics is the difficulty in powering millimeter-sized electronics devices without using batteries, which compromise biocompatibility and long-term residence. We examined the feasibility of leveraging mid-field wireless powering to transfer power from outside of the body to electronics at various locations along the GI tract...

REVIEW
Kei Asayama
Although antihypertensive therapy reduces cardiovascular risk, individuals who are treated with antihypertensive medication generally have a worse prognosis for cardiovascular disease than untreated people. We recently evaluated the impact of conventional blood pressure level based on two Japanese individual participant databases and found that conventional blood pressure at baseline was not or was weakly associated with cardiovascular events among patients under antihypertensive drug medication. In the general population in Ohasama and the Hypertension Objective Treatment Based on Measurement by Electrical Devices of Blood Pressures study, self-measured home blood pressure significantly predicted cardiovascular outcomes in patients under antihypertensive treatment...

BACKGROUND: The Physician Consortium for Performance Improvement recently proposed percutaneous coronary intervention (PCI)-specific process measures. However, information about hospital performance on these measures and the association of PCI process and outcomes measures are not available. METHODS AND RESULTS: We linked the National Cardiovascular Data Registry (NCDR) CathPCI Registry with Medicare claims data to assess hospital performance on established PCI process measures (aspirin, thienopyridines, and statins on discharge; door-to-balloon time; and referral to cardiac rehabilitation), newly proposed PCI process measures (documentation of contrast dose, glomerular filtration rate, and PCI indication; appropriate indication for elective PCI; and use of embolic protection device), and a composite of all process measures...

Kylie H Jackson, Sandra J Mixer
The growing number of Spanish speakers in the United States poses communication challenges for healthcare providers. Language barriers in pediatric acute care have been associated with an increased risk for adverse events, longer hospital stays, and decreased quality of care. In addition, clinicians' usage of interpreter services is inconsistent. In fact, nurses often lack interpreter support during daily bedside care. Nursing staff at a pediatric children's hospital in the southeastern United States identified bedside communication with Spanish-speaking patients and families as a clinical challenge...

REVIEW
H Stege, J Krutmann
Actinic keratosis is one of the most common skin diseases. Because of the ongoing demographic changes, it is anticipated that the incidence will further increase. Prevention of actinic keratoses is thus of great importance. By far the most important cause of actinic keratoses is the chronic cumulative irradiation of human skin with ultraviolet B and A radiation from natural sunlight. There is no doubt that use of sunscreens is effective in preventing actinic keratoses. Recent studies indicate that in high-risk groups the regular use of medical devices which are characterized by a very high SPF and which contain liposomally encapsulated DNA repair enzymes are effective in preventing the development of new actinic keratoses even when field cancerization is already present in human skin...

Andrew G Mark, Emmanuel Suraniti, Jérôme Roche, Harald Richter, Alexander Kuhn, Nicolas Mano, Peer Fischer
A variety of diagnostic and therapeutic medical technologies rely on long term implantation of an electronic device to monitor or regulate a patient's condition. One proposed approach to powering these devices is to use a biofuel cell to convert the chemical energy from blood nutrients into electrical current to supply the electronics. We present here an enzymatic microbiofuel cell whose electrodes are directly integrated into a digital electronic circuit. Glucose oxidizing and oxygen reducing enzymes are immobilized on microelectrodes of an application specific integrated circuit (ASIC) using redox hydrogels to produce an enzymatic biofuel cell, capable of harvesting electrical power from just a single droplet of 5 mM glucose solution...

Excitation and manipulation of surface plasmons (SPs) are essential in developing cutting-edge plasmonic devices for medical diagnostics, biochemical spectroscopy and communications. The most common approach involves designing an array of periodic slits or grating apertures that enables coupling of the incident light to the SP modes. In recent years, plasmonic resonances, including extraordinary optical transmission through periodic arrays, quasicrystals and random aperture arrays, have been investigated in the free space...

BACKGROUND: Pre-hospital airway management is a major challenge for emergency medical service (EMS) personnel. Despite convincing evidence that the rescuer's qualifications determine efficacy of tracheal intubation, in-hospital airway management training is not mandatory in Austria, and often neglected. Thus we sought to prove that airway management competence of EMS physicians can be established and maintained by a tailored training program. METHODS: In this descriptive quality control study we retrospectively evaluated all in- and pre-hospital airway cases managed by EMS physicians who underwent a structured in-hospital training program in anesthesia at General Hospital Wiener Neustadt...

Intrathecal baclofen therapy has become increasingly popular because of its effectiveness in treating spasticity in pediatric patients. The device implanted into each patient is structurally similar. However, x-ray imaging can give the appearance of missing or extraneous objects on or near the intrathecal baclofen device. The composition of the material used in making the catheters is transparent on x-ray images. In addition, the connection port between the pump and catheter resembles the shape of a needle...

PURPOSE OF REVIEW: Cardiac transplant remains the gold standard of care for patients with end-stage heart failure. Unfortunately, due to the limited availability of donor hearts in the United States, not all eligible candidates are able to be transplanted. Since the introduction of mechanical assist devices for the treatment of advanced heart failure, patients gain a significant survival benefit while awaiting transplant. With rapidly evolving technology, it is important to appreciate the advances in the current use of mechanical assist devices...

Massimiliano Sorbello, Flavia Petrini
In the crowded world of supraglottic airway devices (SADs), many papers compare the easiness of insertion based on the different endpoints of an operator's satisfaction: first pass success, ventilation effectiveness, complications and morbidity. Proseal LMA(™) (Laryngeal Mask Airway, Teleflex Medical, Dublin, Ireland) has been extensively studied because on one hand it has a steeper learning curve and more complex insertion when compared with other SADs and on the other hand many alternative techniques are available to facilitate insertion...
