ABSTRACT
The years since 2000 have been a golden age in in situ ocean observing with the proliferation and organization of autonomous platforms such as surface drogued buoys and subsurface Argo profiling floats augmenting ship-based observations. Global time series of mean sea surface temperature and ocean heat content are routinely calculated based on data from these platforms, enhancing our understanding of the ocean's role in Earth's climate system. Individual measurements of meteorological, sea surface, and subsurface variables directly improve our understanding of the Earth system, weather forecasting, and climate projections. They also provide the data necessary for validating and calibrating satellite observations. Maintaining this ocean observing system has been a technological, logistical, and funding challenge. The global COVID-19 pandemic, which took hold in 2020, added strain to the maintenance of the observing system. A survey of the contributing components of the observing system illustrates the impacts of the pandemic from January 2020 through December 2021. The pandemic did not reduce the short-term geographic coverage (days to months) capabilities mainly due to the continuation of autonomous platform observations. In contrast, the pandemic caused critical loss to longer-term (years to decades) observations, greatly impairing the monitoring of such crucial variables as ocean carbon and the state of the deep ocean. So, while the observing system has held under the stress of the pandemic, work must be done to restore the interrupted replenishment of the autonomous components and plan for more resilient methods to support components of the system that rely on cruise-based measurements. © 2023 American Meteorological Society.
ABSTRACT
The impact of coronavirus disease (COVID-19) in intervened patients seems to cause large postoperative mortality, although its incidence varies among centres. Primary aim was to evaluate the incidence of COVID-19 on the patients intervened in our General and Digestive Surgery Department, during the maximum impact of the pandemia in Spain. Secondary outcomes were evaluating perioperative mortality, and determining the risk factors for COVID-19 infection. Materials and Method: Retrospective single centre study of consecutive patients undergoing general and gastrointestinal surgical procedures with more than 24 hours of in-hospital stay, from February 1, 2020 to April 30, 2020 in a tertiary referral centre in Madrid, Spain. Results: A total of 441 patients were analysed: 423 were non-COVID-19 patients while 18 of them had COVID-19. Preoperative and operative characteristics were similar for both groups, unless for the American Society of Anesthesiologists grade. The incidence of COVID-19 in our intervened patients was 4.1%. Postoperative mortality was high among surgical patients with COVID-19, with a mortality rate of 22.2% compared to a 2.8% in non COVID-19 patients. The risk factors for COVID-19 infection were a prolonged postoperative stay (OR: 1.035 [95% CI: 1.007-1.065]) and the need of a reintervention (OR: 5.025 [95% CI: 1.650-15.311]). Conclusion: Surgical interventions during the COVID-19 pandemia resulted in a low infection rate but a high postoperative COVID-19 mortality. The decision to intervene must be carefully balanced against the additional risk for patients in a high transmission setting. © 2021, Sociedad de Cirujanos de Chile. All rights reserved.
