Early initiation of remdesivir and its effect on oxygen desaturation: A clinical review study among high-risk COVID-19 patients in Myanmar.

Background: Although Remdesivir has been evaluated for the treatment of coronavirus disease 2019 (COVID-19), few study has yet shown effective mortality reduction. It might be because, in almost all those studies, remdesivir therapy was started beyond 7th days from the onset of symptoms when the active viral replications have already gone. Methods: This study reviewed the effectiveness of early remdesivir therapy during viral phase of COVID-19 and safety of its administration at home or community care during the outbreak of COVID-19 from July to September 2021 in Myanmar. We retrospectively reviewed clinical records of 204 high risk COVID-19 patients who had received remdesivir therapy within 7 days from the onset of illness and before oxygen desaturation. Findings: All patients received remdesivir therapy according to standard five days course of 200 mg loading dose on day 1, followed by 100 mg daily for up to 4 additional days. Out of 204 patients, 60.75% (124/204) were aged 60 years and above with comorbidity; 21.1% (43/204) aged under 60 years with comorbidity and 18.1% (37/204) were aged more than 60 years old without comorbidity. The patients who received RDSV therapy within 1-4 days and within 5-7 days were 50.5% (103/204) and 49.5% (101/204) respectively. All patients survived to 21 days without ICU admission or mechanical ventilation. Eighty six percent of patients had no hypoxia and only five percent had moderate to severe hypoxia, requiring oxygen. Those who received RDSV therapy within 1 to 4 days from the onset of symptoms had significantly lower rate of hypoxia compared to those who received remdesivir therapy on 5 to 7 days. After RDSV therapy, increased lymphocyte count and decreased CPR were observed in 74.5% (152/204) and 52.9% (108/204) of the patients respectively. There was no report of major adverse events. Conclusion: Remdesivir, if given within first 4 days from the onset of symptoms, is the most effective strategy for prevention of oxygen desaturation, further progression of COVID-19 and death although it is still beneficial if given later, days 5 to 7. It is a safe drug to be prescribed in hospital at home care. It may be cost-benefit if high-risk group of patients with COVID-19 were selected for early remdesivir therapy in the community.

Seroprevalence of SARS-CoV-2 antibodies, associated factors, experiences and attitudes of nursing home and home healthcare employees in Switzerland.

BACKGROUND: Many studies in hospital settings exist and have shown healthcare employees to be particularly exposed to SARS-CoV-2. While research focused on hospital staff, little evidence exists for employees in nursing homes and home care. The aims of this study were to assess the seroprevalence in nursing homes and home care employees in the Canton of Zurich, compare it to the general population, assess factors associated with seropositivity and explore the perspective of the employees regarding how the pandemic changed their daily work. METHODS: This cross-sectional study is part of the national Corona Immunitas research program of coordinated, seroprevalence studies in Switzerland. Six nursing homes and six home healthcare organizations providing at home care services in Zurich were selected and 296 and 131 employees were recruited, respectively. Assessments included standardized questionnaires, blood sampling for antibodies, and additional work-specific questions. All participants were recruited between 21st September and 23rd October 2020, before the second wave of the pandemic hit Switzerland, and were possibly exposed to SARS-CoV-2 at their work during the first wave in spring 2020. RESULTS: Seroprevalence of SARS-CoV-2 was 14.9% (95% CI 11.1%-19.6%; range 3.8% to 24.4%) for nursing home employees and 3.8% (95% CI 1.4-9.1%; range 0% to 10%) for home healthcare employees, compared to the general population of Zurich at 3.5% in September 2020 for those aged 20-64. Nurses were 2.6 times more likely to have SARS-CoV-2 antibodies than those employees who were not nurses (95% CI 1.1-6.2). The employees (nursing homes vs. home healthcare) perceived the implementation of general safety measures (44.9% vs. 57.3%) and wearing masks during work (36.8% vs. 43.5%), especially due to the limited communication with residents/clients, as the most crucial changes. CONCLUSIONS: Nursing home employees who worked through SARS-CoV-2 outbreaks at their work were substantially more affected by SARS-CoV-2 infection compared to the general population and to home healthcare employees who similarly worked through outbreaks in their communities. Employees reported that important resources to cope with the burdensome changes they perceived in their daily work were personal resources and team support.

Flexible care in breast cancer.

Treatment of patients with cancer in hospitals or clinics is resource-intensive and imposes a burden on patients. 'Flexible care' is a term that can be used to describe treatment administered outside the oncology ward, oncological outpatient clinic or office-based oncologist setting. Programmes that reduce travel burden by bringing cancer treatment to the patient's home, workplace or closer to the patient's home, in the form of satellite clinics or mobile cancer units, expand treatment capacity and are well received. Clinical trial data show that, compared with intravenous administration, subcutaneous (s.c.) administration of trastuzumab is preferred by patients with breast cancer (BC), saves healthcare professionals' (HCPs) time, reduces drug preparation and administration time and reduces direct and indirect costs. As such, s.c. trastuzumab is well suited to flexible care. The results of a Belgian study (BELIS) show that home administration of s.c. trastuzumab is feasible and preferred by patients with BC. Numerous programmes and pilot studies in Europe show that s.c. trastuzumab can be administered effectively in the patient's home, in primary care settings or local hospitals. Such programmes require planning, training, careful patient selection and technology to link patients, caregivers and specialists in oncology clinics. Once these elements are in place, flexible care offers patients with BC a choice of how treatment may be delivered and lead to improved quality of life, while reducing pressure on HCPs and hospitals. The concept of flexible care is particularly relevant amid the COVID-19 pandemic where guidelines have been developed encouraging remote care.
