Early Safety Monitoring of COVID-19 Vaccines in Healthcare Workers.

Hospital-based surveillance for adverse events was conducted on healthcare workers after they received the first dose of coronavirus disease 2019 (COVID-19) vaccine. Among the two new platform vaccines (messenger RNA- and adenoviral vector-based vaccines), the rates of systemic adverse events were significantly higher among adenovirus-vectored vaccine recipients. Fatigue (87.6% vs. 53.8%), myalgia (80.8% vs. 50.0%), headache (72.0% vs. 28.8%), and fever (≥ 38.0°C, 38.7% vs. 0%) were the most common adverse events among adenovirus-vectored vaccine recipients, but most symptoms resolved within 2 days. Both types of COVID-19 vaccines were generally safe, and serious adverse events rarely occurred.

The role of smart monitoring digital health care system based on smartphone application and personal health record platform for patients diagnosed with coronavirus disease 2019.

BACKGROUND: The massive outbreak of the novel coronavirus disease 2019 (COVID-19) in Daegu city and Gyeongsangbuk-do, Republic of Korea (ROK), caused the exponential increase in new cases exceeding 5000 within 6 weeks. Therefore, the community treatment center (CTC) with a digital health care monitoring system based on the smartphone application and personal health record platform (PHR) was implemented. Thus, we report our experience in one of the CTCs to investigate the role of CTC and the feasibility of the digital health care monitoring system in the COVID-19 pandemic. METHODS: The Gyeongbuk-Daegu 2 CTC was set up at the private residential facility. Admission criteria were 1) patients < 65 years with COVID-19, 2) patients without underlying medical comorbidities, and 3) COVID-19 disease severity of mild class. Admitted patients were placed under monitoring of vital signs and symptoms. Clinical information was collected using the smartphone application or telephone communication. Collected information was displayed on the PHR platform in a real-time fashion for close monitoring. RESULTS: From Mar 3, 2020, to Mar 26, 2020, there was a total of 290 patients admitted to the facility. Males were 104 (35.9%). The median age was 37 years. The median time between the COVID-19 diagnosis and admission was 7 days. Five patients were identified and were transferred to the designed COVID-19 treatment hospital for their urgent medical needs. The smartphone application usage to report vital signs and symptoms was noted in 96% of the patients. There were no deaths of the patients. CONCLUSIONS: Our results suggest that implementation of the CTC using a commercial residence facility and digital health care technology may offer valuable solutions to the challenges posed by the COVID-19 outbreak.

Innovative countermeasures can maintain cancer care continuity during the coronavirus disease-2019 pandemic in Korea.

BACKGROUND: Even though Korea was known to have the highest number of coronavirus disease-2019 (COVID-19) infection in the early phase of the pandemic, Korea was able to successfully flatten the curve in a short period of time without extreme measures. We compared the status of cancer management before and after COVID-19 and analysed how cancer care continuity was maintained in Korea. PATIENTS AND METHODS: We investigated the medical records on the number of cancer diagnosis, cancer surgery, radiation therapy and scheduled chemotherapy conducted in Korea University Anam Hospital from January 1 to April 30, 2019 and from the same period in 2020. We also collected the data of metastatic cancer patients who were hospitalised due to respiratory disease. RESULTS: Of all diagnoses, 1694 cancer diagnoses were made in the study period of 2019, and 1445 diagnoses in 2020 (decreased by 14.7%); the cancer surgery performed 830 and 800 cases; the set-up for radiation therapy decreased from 185 to 140 cases; the number of systemic chemotherapies for metastatic cancer patients treated in department of medical oncology increased from 2555 to 2878 cases. Among hospitalised patients, emergency centre visit, intensive care unit admission, discharge after recovery and death reveal no drastic changes. CONCLUSIONS: Routine cancer care for patients with metastatic cancer has been maintained without significant difference before and after the COVID-19 pandemic. The Korean government's innovative countermeasures in the early phase of outbreak made it possible for cancer care practitioners to provide cancer patients with regular care under the standard infection control protocol.
