Standards are important tools in evaluating and predicting the performance of medical devices prior to implantation. There are three types of standards that are available: a material specification, a standard test method, and a standard test guide. Each of these types of standards is defined with examples of how each is used to facilitate evaluation of medical devices. The standards development process is also described: this is a complex process, requiring the involvement of a multidisciplinary team, usually consisting of engineers, scientists, and clinicians who represent healthcare, academia, government, and industry. Finally, standards have a clear and defined role in the development of medical devices, and the benefits, strengths, as well as the limitations in this role are discussed.

Background: Sleep-wake patterns are important behavioral biomarkers for patients with serious mental illness (SMI), providing insight into their well-being. The gold standard for monitoring sleep is polysomnography (PSG), which requires a sleep lab facility; however, advances in wearable sensor technology allow for real-world sleep-wake monitoring.
Objective: The goal of this study was to develop a PSG-validated sleep algorithm using accelerometer (ACC) and electrocardiogram (ECG) data from a wearable patch to accurately quantify sleep in a real-world setting.

This scoping review summarizes two emerging electrical impedance technologies: electrical impedance myography (EIM) and electrical impedance tomography (EIT). These methods involve injecting a current into tissue and recording the response at different frequencies to understand tissue properties. The review discusses basic methods and trends, particularly the use of electrodes: EIM uses electrodes for either injection or recording, while EIT uses them for both.

To understand the environmental burden associated with intravitreal injections (IVIs) and propose actionable solutions to mitigate this impact. An analysis of current IVI practices was conducted, focusing on packaging waste, energy consumption, the carbon footprint, and disposal processes. Data on the environmental footprint of IVIs were collected from the literature and industry reports.

Background: The P300 signal, an endogenous component of event-related potentials, is extracted from an electroencephalography signal and employed in Brain-computer Interface (BCI) devices.
Objective: The current study aimed to address challenges in extracting useful features from P300 components and detecting P300 through a hybrid unsupervised manner based on Convolutional Neural Network (CNN) and Long Short-term Memory (LSTM).
Material And Methods: In this cross-sectional study, CNN as a useful method for the P300 classification task emphasizes spatial characteristics of data.

Background: Loss or displacement of a fat pad on the foot increases plantar pressure, leading to pain and plantar ulcers. These ulcers, especially in patients with diabetic neuropathy, have high recurrence rates, often resulting in amputations. Standard of care focuses on reducing plantar pressure with shoe padding or orthotic devices, leaving the restoration of the fat pad as an unmet medical need.
