Suboptimal patient positioning with panoramic and CBCT imaging: effects on dose.

Objective: This study examined the effects of changes in patient positioning on radiation exposure for panoramic and cone beam computed tomography (CBCT) radiographic examinations by measuring effective dose (E) and equivalent doses.

Study Design: Simulated radiographic examinations with optimal and suboptimal positioning-anterior shift by 1 centimeter (cm), posterior shift by 1 cm, chin lowered by 10 degrees (°), chin elevated by 10°, rotation by 10°, and lateral shift by 1 cm-were conducted using a tissue-equivalent phantom and optically-stimulated luminescent dosimeters. Exposures were made with the RAYSCAN Alpha Plus 160 X-ray unit using the following exposure parameters: panoramic, 80 kVp, 14 mA, and 13.

Oncologic outcomes for invasive squamous cell carcinoma with a clinically resolved biopsy site managed by watchful waiting: A retrospective cohort study.

Background: Treatment of cutaneous squamous cell carcinoma (cSCC) largely involves surgical excision. Few studies have examined oncologic outcomes of tumors managed by watchful waiting (WW) when the lesion appears resolved after the biopsy site has healed.

Objective: To describe oncologic outcomes for patients diagnosed with cSCC that was determined clinically resolved at follow-up and subsequently managed by WW.

Planning postpartum contraception for women with substance use disorders: Utilisation of the birth admission.

Background: Women with substance use disorders (SUD) use less contraception, and experience higher rates of unintended pregnancy, compared to women without SUD. Contraception is discussed at the six-week postnatal appointment, which many women with SUD do not attend. Therefore, it is important women have the opportunity to formulate contraception plans before discharge from the birth admission.

Establishing the Foundations of Emotional Intelligence in Care Companion Robots to Mitigate Agitation Among High-Risk Patients With Dementia: Protocol for an Empathetic Patient-Robot Interaction Study.

Background: An estimated 6.7 million persons are living with dementia in the United States, a number expected to double by 2060. Persons experiencing moderate to severe dementia are 4 to 5 times more likely to fall than those without dementia, due to agitation and unsteady gait.

Analyses and Utilization of Selectively Tuned Human Adipose-Derived Stromal/Stem Cell Exosomes.

We have developed a hollow fiber bioreactor-based production system for manufacturing large quantities of extracellular vesicles (EVs) containing exosomes from adult human adipose-derived stromal/stem cells (ASCs). By manipulating the cellular bioreactor environment, we have found that we can alter ASC EV production, secretion, and surface protein composition. The aims of this chapter are to describe the methodology for culturing and tuning of adipose ASCs in a bioreactor, along with the collection and isolation of the EVs containing exosomes demonstrating increased HSP70 content.
