Background: Although post-endoscopy fever (PEF) without colon perforation or haemorrhage is believed to be rare, incidence, risk factors and causes in the adult population have not been fully investigated. The purpose of the present study was to investigate the incidence of PEF and identify the risk factors associated with the development of PEF and its outcomes. Material and Methods: Over a three-month period, 1054 non-hospitalised patients who had an endoscopic procedure at Cleveland Clinic Abu Dhabi received a post-procedure phone call within the first 24 hours. After identifying patients with fever and obtaining verbal consent, patients were enrolled in the study using a standardised telephone interview. Results: Thirty-four patients with PEF were identified. The highest temperature measured was 39.8 degrees Celsius. Oesophagogastroduodenoscopy, as a single procedure, was the most commonly performed (41.2%). Logistic regression revealed that no significant group differences across procedure types existed in terms of adjusted odds of fever. However, results also indicated that age has a significant negative relationship with fever—higher age is associated with lower odds of fever (b = -0.033, p = 0.024). Conclusion: PEF is an unpleasant side effect and it is associated with patient discomfort, dissatisfaction and fear during post-endoscopy recovery. Although our findings do not fully explain the possible mechanisms underlying post-endoscopy fever, this study data should increase awareness about PEF as a common side effect related to endoscopy.

Given the interdependence of multiple factors in age-related vestibular loss (e.g., balance, vision,cognition), it is important to examine the individual contributions of these factors with ARVL. While therelationship between the vestibular and visual systems has been well studied (Bronstein et al., 2015),little is known about the association of the peripheral vestibular system with neurodegenerative disorders (Cronin et al., 2017). Further, emerging research developments implicate the vestibular system asan opportunity for examining brain function beyond balance, and into other areas, such as cognition andpsychological functioning. Additionally, the bidirectional impact of psychological functioning is understudied in ARVL. Recognition of ARVL as part of a multifaceted aging process will help guide thedevelopment of integrated interventions for patients who remain at risk for decline. In this review, wewill discuss a wide variety of characteristics of the peripheral vestibular system and ARVL, how it relatesto neurodegenerative diseases, and correlations between ARVL and balance, vision, cognitive, and psychological dysfunction. We also discuss clinical implications as well as future directions for research, withan emphasis on improving care for patients with ARVL.

There exists a great need for the development of high performance alloys due to increasing demands for energy conservation and environmental protection. Application of strip casting shows a strong potential for the improvement of properties of existing alloys and also for the development of novel alloy systems with superior properties. The present paper reviews our Center's activities in the development of high performance alloys by strip casting. Examples include (1) Al alloys, (2) wrought Mg alloys, and (3) bulk metallic glass (BMG) alloys.
