ABSTRACT

NASA's Double Asteroid Redirection Test (DART) successfully intercepted the asteroid Didymos on September 26th of 2022, potentially changing its orbital period with a deflection by kinetic impact. The spacecraft launched aboard a SpaceX Falcon 9 rocket on November 24th, 2021. DART's Integration and Test (I&T) campaign was scheduled to commence in April of 2020 at the Johns Hopkins University Applied Physics Laboratory (JHU/APL) in Laurel, Maryland. In March of that year, one month prior to beginning I&T, the rapid spread of the Coronavirus (COVID-19) forced JHU/APL to rethink how to assemble, test and deliver a spacecraft on schedule during a very challenging period of time. This paper will discuss the details of the successful I&T strategy used by the DART team during the COVID-19 lockdown and subsequent return to post-lockdown life. The team learned how to effectively meet virtually, how to integrate hardware, and how to operate the spacecraft with the least amount of people required. Communication was key in keeping the various DART team members, who were located across the country, connected and safe. The team had also moved documentation online for the first time, which turned out to be very instrumental in keeping everyone on track. A variety of tools to collaborate and document test procedures and results proved valuable for record keeping. Creative solutions were implemented during the test campaign for scheduling both remote and in person monitoring. This paper will conclude with DART lessons learned and recommendations for future I&T programs. © 2023 IEEE.

ABSTRACT

Background: There is a need to analyze a worldwide database of the coronavirus disease of 2019 (COVID-19) pandemic. This may prove valuable to facilitate better strategies and planning on prevention, screening, surveillance, early diagnosis, containment and treatments. Method: We extracted 14,259 case reports of COVID-19 dated 11th November 2019 to 18th March 2020 from Johns Hopkins University Repository Online Databaseof 58 countries. After extensive data preprocessing, a multi-disciplinary expert researcherthen conducted series of vetting to categorizefree-text description of symptoms into discreet standardizedcategories. Continuous variables were presented by using median and inter-quartile range whereas categorical variables were presented by frequency and percentage. Result: A total of 2191 cases (15.4%) were included for demographic analysis. The median age was46 years (IQR26 years) with 787 (35.9%) cases involved patients aged of 60 and above while patients less than18 years of age were reported in 79 (3.6%) cases. Majority of the patients were males (n=1227, 56.7%). There were a total of 20standardized categories of COVID-19 symptoms. The most prevalent were fever (74.8%), nonproductive cough (42.2%), fatigue (13.1%), sore throat (12.8%) and shortness of breath (11.7%). Other symptoms with frequency of more than 1% were chest discomfort, nasal congestion, muscular pain, chills and rigors, headache, diarrhoea, expectoration and joint pain. Other more uncommon symptoms reported include loss of appetite, conjunctivitis, toothache and abdominal pain. Asymptomatic manisfestations were reported in 8 cases (1.0%). All population are susceptible to COVID-19 especially the older age group. There were 20 standardized categories of symptoms wherefever, non-productive cough, fatigue, sore throat and shortness of breath were the most commonly reported. Conclusion: Findings of this study contribute to a deeper understanding on COVID-19 and may prove useful for researchers to better-design screening and surveillance strategies via more accurate risk-prediction modelling.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of the coronavirus disease (COVID-19) pandemic, has infected millions of people globally. Genetic variation and selective pressures lead to the accumulation of single nucleotide polymorphism (SNP) within the viral genome that may affect virulence, transmission rate, viral recognition and the efficacy of prophylactic and interventional measures. To address these concerns at the genomic level, we assessed the phylogeny and SNPs of the SARS-CoV-2 mutant population collected to date in Iran in relation to globally reported variants. Phylogenetic analysis of mutant strains revealed the occurrence of the variants known as B.1.1.7 (Alpha), B.1.525 (Eta), and B.1.617 (Delta) that appear to have delineated independently in Iran. SNP analysis of the Iranian sequences revealed that the mutations were predominantly positioned within the S protein-coding region, with most SNPs localizing to the S1 subunit. Seventeen S1-localizing SNPs occurred in the RNA binding domain that interacts with ACE2 of the host cell. Importantly, many of these SNPs are predicted to influence the binding of antibodies and anti-viral therapeutics, indicating that the adaptive host response appears to be imposing a selective pressure that is driving the evolution of the virus in this closed population through enhancing virulence. The SNPs detected within these mutant cohorts are addressed with respect to current prophylactic measures and therapeutic interventions.

ABSTRACT

BACKGROUND: The prescription pickup and renewal process in ambulatory care settings requires numerous steps, such as making an appointment with a physician to renew prescriptions and direct pharmacy visits to pick up medications. This process can be difficult or cumbersome for some patients; however, digital health-associated patient portals can reduce the burden on both patients and healthcare professionals. METHODS: A retrospective study was conducted in an ambulatory care setting of Johns Hopkins Aramco Healthcare. We analyzed the utilization pattern of MyChart for medication renewal and refill pickup services for ambulatory care patients of all specialties from October 1, 2018, to September 30, 2020. The data were extracted electronically from the Epic-Hyperspace EHR system, and the effects of factors such as year of access and COVID-19 on MyChart utilization were analyzed. RESULTS: A total of 125,538 patients were registered using MyChart. In the first and second year of this study, MyChart was utilized by 44,063 (8.7%) and 59,622 (13.6%) patients, respectively, for medication pickup. Additionally, in these two years, 92,997 (21.6%) and 156,020 (38.9%) medication refills were requested through MyChart (with no direct pharmacy visit) and collected from different pickup locations, respectively. In two years, there were 363,159 medications sent to physicians for renewal through Epic-MyChart, of which 347,244 (95.6%) were approved and 15,915 (4.4%) were denied. A significant increasing (p less than 0.05) trend in utilization, medication requests, and renewal requests using the MyChart were observed over a period of 24 months and during quarantine due to COVID-19. Although there was a decrease in physicians denying renewal request, these were not significantly affected by time or COVID-19. CONCLUSION: The high and consistent utilization of the patient portal MyChart indicates its broad acceptance, significantly minimizing the barriers to medication pickup and renewal processes in ambulatory care settings. The year of access and COVID-19 were significantly associated with an increasing trend in MyChart utilization. With increased utilization and higher acceptability, the internet-based patient portal MyChart continues to hold great potential for providing quality healthcare services by increasing access and making patients decision-makers in their healthcare.

ABSTRACT

Over the past 20 years, owing to rapid advances in technological innovation, namely in telecommunication and telemedicine, healthcare institutions have integrated clinical practices with cutting-edge telecommunication technology to enhance access to patient care, improve continuity of clinical care, and ensure patient safety. Johns Hopkins Aramco Healthcare (JHAH) is a gold-certified tertiary care institution, and it is an excellent center for patient-centered care. In response to the Coronavirus 2019 (COVID-19) pandemic, it has adopted various telecommunication technologies to provide patient-care services. This article describes the integration of telecommunication technology, such as telephone and video consultation, with a pharmacist-led medication management clinic (MMC) to provide person-centered patient care services at JHAH. The JHAH pharmacy services were found to be essential in establishing face-to-face outcome-oriented pharmacist-led medication management services for patients requiring chronic ambulatory care. The established tele-MMC services enhanced patient engagement and treatment compliance, and the integration process and its challenges were assessed. Especially during this COVID-19 pandemic, the pharmacist-led tele-MMC services were beneficial to chronic disease patients and ensured the continuity of care, maintenance of up-to-date lab tests, management of polypharmacy, minimization of the use of unwanted medications and medication synchronization. Further, the pharmacist-led tele-MMC services provided comprehensive patient counseling, which included the use of visual aids. This new integrated model provides an example for other healthcare organizations to adopt and implement the program in ambulatory care settings, to better ensure the continuity of quality healthcare, especially for elderly patients and those with chronic diseases.

ABSTRACT

In the early twentieth century, early neurosurgical pioneers marked their claims in the specialty during the combined threats of the Spanish influenza and World War I. Their stories, intimately connected, demonstrate personal and professional losses in the backdrop of overarching perseverance to achieve that which allowed neurosurgery to evolve into modernity. Today, as global order adapts to the severe acute respiratory syndrome coronavirus (SARS-COVID-19) pandemic, their stories provide an opportunity for reflection as we carve our way forward as a specialty.

ABSTRACT

On January 22, 2020, Johns Hopkins University launched its online COVID-19 dashboard to track in real time what began in December as the regional outbreak of a novel coronavirus first identified in Wuhan, China. The dashboard and its format were quickly adopted by other organizations, making global, national, and regional data on the pandemic available to all. The wealth of data freely offered in this way was collected by syndromic programs whose precise algorithms search official and popular sources for data on COVID-19 and other diseases. The dashboard signals a new phase in the maturation of the "digital revolution" from paper resources and, in their popular employ, a "democratizion" of data and their presentation. This perspective thus uses the COVID-19 experience as an example of the effect of this digital revolution on both expert and popular audiences. Understanding it permits a broader perspective on not simply the pandemic but also the cultural and socioeconomic context in which it has occurred.
