ABSTRACT
We evaluate high-frequency bill of lading data for international trade research. These data offer some advantages over both other publicly accessible trade data and confidential datasets, but they also have drawbacks. We analyze three aspects of trade during the COVID-19 pandemic. First, we show how the high-frequency data capture the within-month collapse of trade between the United States and India that are not observable in official monthly data. Second, we demonstrate how U.S. buyers shifted their purchases across suppliers over time during the recovery. And third, we show how the data can measure vessel delivery bottlenecks in near real time.
ABSTRACT
Background. UNC Health Blue Ridge is a nonprofit community teaching hospital with 145 staffed beds. The COVID-19 pandemic has challenged rural hospitals like ours with high occupancy and periodic surges. UNC Health Blue Ridge COVID Virtual Hospital (CVH) created a home monitoring program for enrolled patients with severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection utilizing disease risk stratification and pulse oximeter readings to dictate nurse and clinician follow-up. We report raw data that compare surge levels in our community for the Alpha (B.1.1.7), Delta (B.1.617.2) and Omicron (B.1.1.529) surges. Methods. From April 2020 to present, the CVH enrolled patients diagnosed with COVID-19 based on FDA approved PCR tests. For this , we defined any surge as an outpatient CVH census of greater than 50 patients or an inpatient census of >10 patients. We defined the maximum intensity of the surge as >20% outpatient SARS CoV-2 positivity and a CVH census >100 patients or >20 inpatients with SARS CoV-2 infection. Results. For the outpatient setting, days of surge and maximum intensity were 144 / 98 days for Alpha, 92 / 71 days for Delta, 74 / 47 days for Omicron, respectively. Average daily CVH admissions during surges were 17.7 for Alpha, 26.15 for Delta, and 27.15 for Omicron. Total emergency department (ED) and urgent care visits were 12,765 and 23,696 for Delta, and 9701 and 16102 for Omicron. In the inpatient setting, days of surge and maximum intensity days were 102/76 days for Delta and 78/48 days for Omicron. Our peak inpatient COVID-19 daily census was 51 and 50 patients for Delta and Omicron. Conclusion. Our CVH has enrolled over 8700 patients, and our hospital has not been on diversion during the COVID-19 pandemic, unlike many surrounding hospital systems of similar size. More importantly, the CVH has helped create a sustainable model that gathers local data to aid predictive algorithms and facilitate proactive rather than reactive resource allocations. This virtual model can be adapted for multiple other health conditions in the outpatient setting to improve patient safety and quality care.
ABSTRACT
COVID-19 was declared a global pandemic by the World Health Organization on March 11, 2020. The COVID-19 pandemic and resulting social disruption has left many to struggle with changes to routines and feelings of uncertainty as the impact of the virus continues to unfold. Evidence suggests an increase in symptoms of anxiety, depression, and stress as a result. Given the well-documented association between physical activity and mental health-be it preventing the onset of depressive or anxious symptoms to minimizing the prognosis of certain conditions-we posit more emphasis be placed in health communications on physical activity as a coping strategy for Canadians. As the ramifications of COVID-19 continue, coupled with the concern of a pending second wave, identifying how Canadians are managing stress and mental health can inform the development of interventions aimed at mitigating the negative impact of COVID-19 on adults' overall wellness. Though social interactions and activities might look different right now, Canadians should be actively looking for safe ways to engage in health promoting and socializing behaviors-physical activity is one such behavior. Herein we explore how a representative sample of Canadian adults are coping with increased stress and mental health issues as a result of COVID-19 and identify a potential disconnect between considering physical activity as a strategy to support social connection and stress management and how Canadians are coping with the pandemic. Given the protective role of physical activity in supporting mental health, our perspective is that health communication efforts should focus on the mental health benefits of physical activity particularly during these uncertain times.
