ABSTRACT
The fisheries industry has been one of the most immediate and severely impacted sectors by the COVID-19 pandemic and lockdowns in particular. This study aimed to gather detailed information about the new initiatives that, preferentially on an online basis, emerged worldwide to trade fish and seafood. A special focus was applied on the usefulness of the digital tools in Portugal, which was considered as a case study. From a global view, the European countries resulted in being especially active to launch nationwide campaigns promoting the domestic consumption of fishing products. A total of 122 digital initiatives, distributed among 48 countries, mainly in America, Southern Europe, southeast Asia, and Oceania, were recorded all over the world to sell fish and seafood. Social media (33.6%), mainly though Facebook, WhatsApp, phone, and e-mail (25.4%) were the main channels used for this purpose. In Portugal, the entity responsible for the first-sale of fishing products allowed free access to the five online auctions that operate nowadays in this country. As expected, in 2020, this digital space experienced an increase in both users (94%) and volume of traded products (121%) compared to the previous year. Moreover, eight Portuguese online shops specializing in fresh fish and seafood, operating exclusively on an online basis, were identified in this study. In general, all of them reported an increase in new users during the first lockdown and were required to recruit additional employees to fulfil the added demand. In parallel, questionnaire surveys conducted in this study revealed that only 33% of the Portuguese fisher associations and producers organizations looked for new technologies as a valuable tool during the pandemic situation, being significantly more valued in the Northern region compared to the rest of the country. Aligned with this perception, 57% of fisher trainees in the Northern coast of Portugal opined that the pandemic changed their view on how the fishing catches can be traded, one way being the use of digital tools considered by the majority as an asset to face the arisen challenges. In conclusion, the key role globally played by digital tools to overcome many of the limitations posed by the pandemic, particularly for the small-scale fisheries, is evident. This recent open-minded environment for technological transition is an undoubted advantage for the future generation of fishers to modernize the classic trade channels into more functionally diversified supply chains.
ABSTRACT
Background: Radiological features of the novel 2019 coronavirus disease (COVID-19) have been mainly described in adults. Available literature states that imaging findings in children are similar but less pronounced. The aim of this study is to describe and illustrate the chest computer tomography (CT) features of pediatric COVID-19. Results: This retrospective study was based on the review of all the chest CTs performed in pediatric patients with confirmed COVID-19 disease between March 8th and May 26th 2020 (n = 24). The presence of comorbidities and coinfection was assessed, as well as timing of CT examination in relation to the onset of symptoms. CT findings were categorized as typical, indeterminate, atypical, and negative for COVID-19 according to International Expert Consensus Statement on Chest Imaging in Pediatric COVID-19 Patient Management. This study found that CT findings were abnormal in 17 (71%) patients, with 5 (21%), 9 (38%), and 3 (13%) patients considered to have typical, indeterminate, and atypical findings, respectively. The most common CT patterns were multiple ground-glass opacities (58%), followed by consolidations (50%). Six patients showed predominantly peripheral distribution of parenchymal abnormalities. A halo sign was identified in 3 patients and a perilobular pattern was identified in one of the cases with typical findings. Conclusions: Chest CT findings in children infected with SARS-CoV-2 can be subtle or absent. Besides recognizing typical findings, radiologists should be able to identify features that favor different or concomitant diagnosis.
ABSTRACT
BackgroundThe sudden increase in COVID-19 admissions in hospitals during the SARS-CoV2 pandemic of 2020 has led to onward transmissions among vulnerable inpatients. AimsThis study was performed to evaluate the prevalence and clinical outcomes of Healthcare-associated COVID-19 infections (HA-COVID-19) during the 2020 epidemic and study factors which may promote or correlate with its incidence and transmission in a London Teaching Hospital Trust. MethodsElectronic laboratory, patient and staff self-reported sickness records were interrogated for the period 1st March to 18th April 2020. HA-COVID-19 was defined as symptom onset >14d of admission. Test performance of a single combined throat and nose swab (CTNS) for patient placement and the effect of delayed RNA positivity (DRP, defined as >48h delay) on patient outcomes was evaluated. The incidence of staff self-reported COVID-19 sickness absence, hospital bed occupancy, community incidence and DRP was compared HA-COVID-19. The incidence of other significant hospital-acquired bacterial infections (OHAI) was compared to previous years. Results58 HA-COVID-19 (7.1%) cases were identified. As compared to community-acquired cases, significant differences were observed in age (p=0.018), ethnicity (p<0.001) and comorbidity burden (p<0.001) but not in 30d mortality. CTNS negative predictive value was 60.3%. DRP was associated with greater mortality (p=0.034) and 34.5% HA-COVID-19 cases could be traced to delayed diagnosis in CA-COVID-19. Incidence of HA-COVID-19 correlated positively with DRP (R=0.7108) and staff sickness absence (R=0.7815). OHAI rates were similar to previous 2 years. ConclusionEarly diagnosis and isolation of COVID-19 would help reduce transmission. A single CTNS has limited value in segregating patients into positive and negative pathways.
