The onset of the COVID-19 pandemic required an abrupt shift in how science, technology, engineering, and mathematics (STEM) research was conducted. Many undergraduate mentees and graduate mentors were forced to move into virtual mentoring. This study discusses changes in mentoring methods, research productivity, and the impact on the future plans of both mentors and mentees across six STEM departments.
Introduction
Acute presentations of COVID-19 infection vary, ranging from asymptomatic carriage through to severe clinical manifestations including acute respiratory distress syndrome (ARDS). Longer term sequelae of COVID-19 infection includes lung fibrosis in a proportion of patients. Krebs von den Lungen 6 (KL-6) is a mucin like glycoprotein that has been proposed as a marker of pulmonary epithelial cell injury. We sought to determine whether KL-6 was a marker of 1) the severity of acute COVID-19 infection, or 2) the persistence of symptoms/radiological abnormalities at medium term follow up.
Methods
Prospective single centre observational study.
Results
Convalescent KL-6 levels were available for 93 patients (male 63%, mean age 55.8 years) who attended an 12-week follow up appointment after being admitted to hospital with COVID-19. For 67 patients a baseline KL-6 result was available for comparison. There was no significant correlations between baseline KL-6 and the admission CXR severity score or clinical severity NEWS score. Furthermore, there was no significant difference in the baseline KL-6 level and an initial requirement for oxygen on admission or the severity of acute infection as measured at 28 days. There was no significant difference in the 12-week KL-6 level and the presence or absence of subjective breathlessness but patients with abnormal CT scans at 12 weeks had significantly higher convalescent KL-6 levels compared to the remainder of the cohort (median 1101 IU/ml vs 409 IU/ml).
Conclusions
The association between high KL-6 levels at 12 weeks and persisting CT abnormalities (GGO/fibrosis), is a finding that requires further exploration. Whether KL-6 may help differentiate those patients with persisting dyspnoea due to complications rather than deconditioning or dysfunctional breathing alone, is an important future research question.
BackgroundLong-term nitrofurantoin (NF) treatment can result in pulmonary and hepatic injury. Current guidelines do not outline the type or frequency of monitoring required for detection of these injuries.AimsTo assess (1) awareness of NF complications among prescribers, (2) monitoring practice and (3) to describe the pulmonary sequelae of NF-related complications.Methods(1) Electronic questionnaire to prescribers, interrogating prescribing/monitoring practices and awareness of complications; (2) Case-note review (June-July 2020) of NF monitoring among general practitioners (GPs) in our local clinical commissioning group; (3) Case review of patients diagnosed with nitrofurantoin-induced interstitial lung disease (NFILD) at our interstitial lung disease (ILD) centre (2014-2020).Results125 prescribers of long-term NF responded to the questionnaire (82% GPs; 12% urologists). Many were unaware of the potential for liver (42%) and lung (28%) complications. 41% and 53% never monitored for these, respectively. Only 53% of urologists believed themselves responsible for arranging monitoring, whilst nearly all GPs believed this to be the prescriber’s responsibility (94%). One third of all respondents considered current British National Formulary (BNF) guidelines “not at all sufficient/clear”, with mean clarity scoring of 2.2/5. Amongst NFILD patients (n=46), NF had been prescribed most often (70%) for treatment of recurrent UTI and 59% (n=27) were prescribed for >6 months. Upon withdrawal of the medication 61% displayed resolution (completely/minimal fibrosis), whilst 16% of patients had progressive lung fibrosis.ConclusionNF can cause marked or irreversible lung complications and there is currently a shortfall in awareness and monitoring. Existing monitoring guidelines should be augmented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
