BACKGROUND: Surgical site infections (SSI) represent a significant public health problem as the most common nosocomial infection and a leading cause of unplanned hospital readmissions among surgical patients. Many develop following hospital discharge and often go unrecognized by patients. Telemedicine offers the opportunity to leverage the mobile technology to remotely monitor wound recovery in the transitional period between hospital discharge and routine clinic follow-up. However, many existing telemedicine platforms are episodic, replacing routine follow-up, rather than equipped for continued monitoring; they include only low-risk patient populations and those who already have access to and comfort with the necessary technology; and transmit no visual information...

This paper presents a novel head-mounted point-of-care diagnostic system for detection and continuous monitoring of Age-related Macular Degeneration (AMD). This wearable embedded open-source platform enables accurate monitoring of AMD by taking advantage of multiple standard graphical interface techniques such as Amsler Grid, Threshold Amsler Grid, Macular Computerized Psychophysical Test and Preferential Hyperacuity Perimeter (PHP). Here, we describe the proposed multi-Grid or so-called NGRID software and elaborate on the hardware prototype...

This paper presents a closed-loop optogenetic stimulation device to achieve online modulation of neurons. The device is designed to be mountable on small rodents in pre-clinical settings. Considering the size of rodents and the need for portability, a single-piece self-contained device is developed which allows real-time photostimulation based on detected neuronal states. It consists of three components: a neural recorder, a control algorithm, and an optogenetic stimulator. The neural recorder which is realized by analogue circuitry measures the neural signal...

Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and compression devices are not as effective as drug. This paper presents a transcutaneous muscle fiber excitation system adaptable for use in seated, walking or lying position...

There has been a push for a greater number of channels in implantable neuroprosthetic devices; but, that number has largely been limited by current hermetic packaging technology. Microfabricated packaging is becoming reality, but a standard testing system is needed to prepare these devices for clinical trials. Impedance measurements of electrodes built into the packaging layers may give an early warning of device failure and predict device lifetime. Because the impedance magnitudes of such devices can be on the order of gigaohms, a versatile system was designed to accommodate ultra-high impedances and allow future integrated circuit implementation in current neural prosthetic technologies...

This paper consists of the design and construction of an intraoperative peritoneal lavage device. It is intended for cleaning the intra-abdominal cavity during a surgical procedure, once the etiology of a peritonitis has been identified and treated. Its purpose is to improve the current standard treatment consisting of simple pouring saline solution. A good washing procedure aids stopping the inflammatory and infectious process generated after the contamination due to the perforation of a hollow viscera. COMSOL Multiphysics software was used to simulate the biomechanical behavior of the liver against localized pressure...

Regulatory authorities require that the safety and efficacy of a new high-risk medical device be proven in a Clinical Trial (CT), in which the effects of the device on a group of patients are compared to the effects of the current standard of care. Phase III trials can run for several years, cost millions of dollars, and expose patients to an unproven device. In this paper, we demonstrate how to use a large group of synthetic patients based on computer modeling to improve the planning of a CT so as to increase the chances of a successful trial for implantable cardioverter defibrillators (ICDs)...

PURPOSE OF REVIEW: The global burden of disease in skin and soft tissue lesions is enormous. Many chronic, poorly healing lesions get treated with antibiotics despite the lack of evidence for long-term antibiotics. There is a global antibiotic resistance crisis driven largely by inappropriate use of large volumes of antibiotics. One solution is to reduce the selection pressure on bacteria by reducing the volume of antibiotic use in medicine, agriculture and the environment. There are few novel antimicrobials...

BACKGROUND: Accurately monitoring and collecting drug adherence data can allow for better understanding and interpretation of the outcomes of clinical trials. Most clinical trials use a combination of pill counts and self-reported data to measure drug adherence, despite the drawbacks of relying on these types of indirect measures. It is assumed that doses are taken, but the exact timing of these events is often incomplete and imprecise. OBJECTIVE: The objective of this pilot study was to evaluate the use of a novel artificial intelligence (AI) platform (AiCure) on mobile devices for measuring medication adherence, compared with modified directly observed therapy (mDOT) in a substudy of a Phase 2 trial of the α7 nicotinic receptor agonist (ABT-126) in subjects with schizophrenia...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

BACKGROUND: Enhanced recovery after surgery (ERAS) programs are aimed at minimizing postoperative stress and accelerating postoperative recovery by implementing multiple perioperative principles. "Early mobilization" is one such principle, but the quality of assessment and monitoring is poor, and evidence of improved outcome is lacking. Activity trackers allow precise monitoring and automatic feedback to the patients to enhance their motivation for early mobilization. The aim of the study is to monitor and increase the postoperative mobilization of patients by giving them continuous automatic feedback in the form of a step count using activity-tracking wristbands...

BACKGROUND: Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across the abdomen. Endovascular abdominal aortic aneurysm repairs (EVARs) are now a common alternative. In this procedure, the common femoral artery is exposed via a cut-down approach and a graft introduced to the aneurysm in this way...
