Background: Single-sided deafness (SSD) and asymmetric hearing loss (AHL) have recently been proposed as a new indication for cochlear implantation. There is still no recommended treatment for these hearing deficits, and most options considered rely on the transfer of sound from the poor ear to the better ear, using Contralateral Routing of the Signal (CROS) hearing aids or bone conduction (BC) devices. In contrast, cochlear implantation allows the poor ear to be stimulated and binaural hearing abilities to be partially restored. Read More

Erectile dysfunction (ED) is important to a man's well-being and health, since it not only affects the individual but also causes strain on a couple's lifestyle and relationship. There are multiple non-invasive treatments that exist for ED including lifestyle changes, oral medications (phosphodiesterase type 5 inhibitors), vacuum-assisted erectile devices, and intraurethral suppositories. While lifestyle changes and oral medications are typically first-line treatments for ED, more-invasive treatments including intracavernosal injections and surgically implanted prosthetic devices may be required for the management of complex cases.

Magnesium (Mg) and its alloys have shown attractive biocompatibility and mechanical strength for medical applications, but low corrosion resistance of Mg in physiological environment limits its broad clinical translation. Hydroxyapatite (HA) nanoparticles (nHA) are promising coating materials for decreasing degradation rates and prolonging mechanical strength of Mg-based implants while enhancing bone healing due to their osteoconductivity and osteoinductivity. Conformal HA coatings with nano-to-submicron structures, namely nHA and mHA coatings, were deposited successfully on Mg plates and rods using a transonic particle acceleration (TPA) process under two different conditions, characterized, and investigated for their effects on Mg degradation in vitro.

Previous work showed that economic decisions can be made independently of spatial contingencies. However, when goods available for choice bear different action costs, the decision necessarily reflects aspects of the action. One possibility is that "stimulus values" are combined with the corresponding action costs in a motor representation, and decisions are then made in actions space. Read More

In tonal languages, voice pitch inflections change the meaning of words, such that the brain processes pitch not merely as an acoustic characterization of sound but as semantic information. In normally-hearing (NH) adults, this linguistic pressure on pitch appears to sharpen its neural encoding and can lead to perceptual benefits, depending on the task relevance, potentially generalizing outside of the speech domain. In children, however, linguistic systems are still malleable, meaning that their encoding of voice pitch information might not receive as much neural specialization but might generalize more easily to ecologically irrelevant pitch contours.

Leadless pacemaker therapy now represents a reality in the field of cardiac pacing. It was developed with the aim of reducing post-procedural complications due to endocavitary leads and with the intention to propose itself as a valid alternative in patients who have contraindications to conventional pacing. Leadless pacemakers to date allow right ventricular stimulation and are implanted through a percutaneous venous femoral access. Read More

Background: 3,4-methylenedioxypyrovalerone (MDPV) toxicity includes intense neurological and cardiovascular events. We examined MDPV-induced cardiovascular, temperature, and locomotor effects following escalating and repeated MDPV administration in adult male and female Sprague-Dawley rats and compared these effects to cocaine in male rats.
Methods: Telemetry devices were surgically implanted to allow continuous measurement of cardiovascular, temperature, and locomotor activity over a 22 h period after dosing. Read More

Negative Pressure Wound Therapy (NPWT) has been shown to limit downgrowth around percutaneous devices in a guinea pig model. However, the influence of NPWT on peri-prosthetic tissue characteristics leading to limited downgrowth is still unclear. In order to investigate this, 12 CD hairless rats were assigned into two groups, NPWT and Untreated (n = 6/group). Read More

The recent increase in the number of patients with implanted peripherally inserted central catheters (PICCs) requires physicians to be familiar with rare and unusual complication-pinch-off syndrome (POS). We present a case of a 40-years-old female with human epidermal growth factor receptor type 2 (HER2)-positive breast cancer and implanted Groshong PICC (BARD). The patient was admitted for an elective chest and abdomen CT angiography control after finishing her trastuzumab and paclitaxel chemotherapy course a month earlier. Read More

Sepsis and septic shock represent medical emergencies with persistently high mortality rates. According to the lately revised Surviving Sepsis Campaign (SSC) guidelines, focus identification/pathogen detection and the initial administration of broad-spectrum antibiotics are to be secluded within one hour after recognition of the symptoms of sepsis. However, there is dispute concerning the so called hour-1 bundle. Read More

A new category of hearing technology has emerged that comprises devices inserted deep into the ear canal. Although not implanted, they represent an extension of what is expected of a traditional hearing aid. There are advantages to these devices, but they are not suited for all individuals with hearing loss. Read More

Russia is the largest country in the world based on the landmass, covering more than one-eighth of the earth's inhabited area. Russia faces challenges in electrophysiology (EP) care including insufficient and uneven financing, complicated system for identifying optimal treatment for individual patients, relative paucity of reasonable educational and certification scope for electrophysiologists, suboptimal national statistical data gathering regarding heart rhythm disorders and EP devices in use, and weak networking of medical information. In comparison with the average level of EP utilization in ESC countries, Russia utilizes around 50% in pacemaker; 10% in ICD; 8% in cardiac resynchronization therapy; 55% in ablations; and 45% in AF ablations.

Antibacterial coatings that eliminate initial bacterial attachment and prevent subsequent biofilm formation are essential in a number of applications, especially implanted medical devices. Although various approaches, including bacteria-repelling and bacteria-killing mechanisms, have been developed, none of them have been entirely successful due to their inherent drawbacks. In recent years, antibacterial coatings that are responsive to the bacterial microenvironment, that possess two or more killing mechanisms, or that have triggered-cleaning capability have emerged as promising solutions for bacterial infection and contamination problems.

Introduction: For children with conductive or mixed hearing loss, in whom use of conventional hearing aids is impossible or limited, use of bone conduction devices is recommended. The choice between the available types of devices depends mostly on the degree of hearing loss, age, and anatomical conditions. One device application in children older than 5 years is the Bonebridge implant. Read More
