Source: Sharon Bord, MD, Department of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA When monitoring patients, it is important to obtain values that are accurate and reliable. Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.

Body segmental inertial properties are required for inverse dynamics modeling. Using an oscillation and reaction board technique, inertial properties of below-knee prostheses were measured. Using direct measures of prosthesis inertia in the inverse dynamics model of the prosthetic leg resulted in lower magnitudes of resultant joint forces and moments.

Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA For unstable patients requiring urgent administration of medications, fluids, or blood products, establishing vascular access quickly is essential. However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Internal lung surface area (ISA) is a critical criterion for assessing lung morphology and physiology in lung diseases and injury-induced alveolar regeneration. We describe here a standardized method that can minimize the measurement bias for ISA in both lung pneumonectomy and prosthesis implantation mouse models.

Neural-machine interfaces (NMI) have been developed to identify the user's locomotion mode. These NMIs are potentially useful for neural control of powered artificial legs, but have not been fully demonstrated. This paper presented (1) our designed engineering platform for easy implementation and development of neural control for powered lower limb prostheses and (2) an experimental setup and protocol in a laboratory environment to evaluate neurally-controlled artificial legs on patients with...
FAQs
Fixation is selected according to the tissue involved, the device being used, and the clinical goal. These factors also influence how the prosthesis is aligned with surrounding anatomy and how the recipient site is prepared. Matching the securing approach to these conditions helps clinicians pursue structural stability while supporting later healing and functional use.
Alignment connects the artificial device's position to the anatomy around it, rather than treating placement as an isolated step. Appropriate alignment supports the intended structural relationship and provides a basis for assessing function during follow-up. Clinicians can then evaluate whether alignment, stability, tissue response, and functional performance are consistent with the procedure's goal.
Healing and rehabilitation are part of the pathway to functional use, not merely activities after surgery. Healing allows the recipient site and surrounding tissues to respond to the device, while rehabilitation supports the return or development of practical function. Follow-up assessment can then examine whether function, alignment, and tissue response are progressing as intended.
The clinical objective changes with the body region and reconstructive need. Joint replacement may focus on restoring function, limb reconstruction may address missing structure, and dental restoration may replace a lost body structure. Other reconstructive procedures may emphasize structural support or stability. Across these settings, device choice, alignment, fixation, and follow-up remain tied to the specific goal.
Follow-up evaluates four connected outcomes: functional use, anatomical alignment, tissue response, and potential complications. These observations help clinicians determine whether the device is supporting the intended clinical purpose and whether recovery is progressing appropriately. Rehabilitation findings can add practical information about use, while tissue and alignment assessments address the local structural response.
It is used when a missing body part requires replacement or when a structure needs support or improved stability. The overview identifies joint replacement, limb reconstruction, dental restoration, and other reconstructive procedures as applications. This range makes the approach relevant to both functional restoration and structural reconstruction, with the operative plan adapted to the body site and clinical objective.
