    (2022-08-07) Alyami, Bandar; Alghamdi, Mohammed; Weissbach, Robert; Lin, William; Pash, Phil; Freije, Elizabeth
    This project aims to create a cape of wonders club that includes technologies. This cape is a square piece of fabric material with electronics inside it, including a blood alcohol sensor, noise sensor, user input screen, and visual display. The electronics are integrated using a microcontroller, which acts as a brain to operate each electronic device. Two battery banks are built to power the electronics and ensure that the project can run for at least 6 hours. The project's two sensors are designed to produce readings. The blood alcohol sensor indicates the level of ethanol in the cape user's blood and displays the results to determine whether the user is below the legal limit or not. The noise sensor reads the music sound in the nightclub and converts it into patterns, which are then shown on the visual display. The visual display, on the other hand, will function as an output, displaying the music patterns. Furthermore, the visual display will exhibit emojis and shapes. The user input screen will allow the user to choose amongst Emojis, shapes, and patterns to be represented in the visual display. The developers of the project will work on building, coding, soldering, and testing these electronics to ensure that they function properly. They will ensure that this club cape is well-made and that it seems fashionable and appealing to the customers of the nightclub cape.

    Clinical Features and Outcome of Low and High Corticosteroids in Admitted COVID-19 Patients
    (Atlantis Press, 2021-09) AlBahrani, Salma; Al-Tawfiq, Jaffar A.; Jebakumar, Arulanantham Zachariah; Alghamdi, Mohammed; Zakary, Nawaf; Seria, Mariam; Alrowis, Abdulrahman; Medicine, School of Medicine
    Introduction: There is no specific anti-viral therapies for 2019 Coronavirus Diseases (COVID-19) infection. Here, we compared patients receiving steroids at different dosages versus no steroids in severe and critical COVID-19 patients. Methods: We retrospectively studied COVID-19 patients who received low-dose or high-dose corticosteroid therapy...

    Initial viral cycle threshold values in patients with COVID-19 and their clinical significance
    (BMC, 2022-06-28) AlBahrani, Salma; Alghamdi, Mohammed; Zakary, Nawaf; Jebakumar, Arulanantham Zechariah; AlZahrani, Samirah Jamaan; ElGezery, Mohamed Hany; Abdallah, Khaled Omar; Al‑Tawfiq, Jaffar A.; Medicine, School of Medicine
    Background: The connection between initial viral cycle threshold (Ct) values of the SARS-CoV-2 with symptoms and hospital course is not clearly studied. Methods: This is a retrospective study of hospitalized COVID-19 patients from Jun 1st 2020 to March 30th, 2021 examining the relationship between initial viral cycle threshold (Ct) values of SARS-CoV-2 as obtained from nasopharyngeal samples. The clinical presentations and outcomes were analyzed in relation to the initial Ct values. Results: The study included 202 hospitalized COVID-19 patients with a mean age (± SD) of 54.75 (± 15.93) and 123 (60.9%) males and 79 (39.1%) females. Of all the patients, the most frequent comorbidity was diabetes mellitus (95; 47%) and the most frequent symptoms were fever (148; 73.3%) and cough (141; 69.8%). There was no significant difference in relation to underlying conditions, clinical presentation, radiographic and laboratory data among those with low, medium and high Ct values. The mean Ct values showed no statistical change over the 10-month study period. Conclusions: Initial SARS-CoV-2 Ct values did not show any association with clinical symptoms and did not predict the need for mechanical intubation or death.
