Tentative plans in our professional and personal lives run the risk of being dashed, although I hope that, by the time this Editorial is printed, the United Kingdom at least may be free of most restrictions. I continue to receive many Covid-related articles describing and analysing datasets in a variety of environments. One area, however, where burgeoning research has undoubtedly benefitted and exploded over the last 18months is in the field of lung ultrasound. We always knew ultrasound could have a significant role in the management of this disease if training and equipment issues are addressed. Lung ultrasound is here to stay and will continue to be applied to situations other than the Covid lung long after the pandemic. It gives me pleasure therefore to offer an insightful guest editorial this month from three clinicians, with a passion for ultrasound, based in the south of the UK. In addition to their work and our usual Echoes page, I offer the usual broad spectrum of article types and topics including a review, a pictorial essay, three original research papers and three informative case reports. You will see that despite differing conditions, many of the articles have the same goal; the desire to detect diseases more quickly, thus allowing for earlier treatment plans. This goal aligns very much with current UK government health initiatives and likely reflects similar aims internationally. First up is a review by Venables et al. who found that raised renal resistive indices could be as reliable a predictor of early diabetic kidney disease as albuminuria levels and more reliable than estimated glomerular filtration rate. Next, a team from Delhi looked at nerves in diabetic patients with and without diabetic polyneuropathy and identified changes on ultrasound which, when compared with a control group of healthy volunteers, may precede clinical symptoms. They suggest that high resolution ultrasound could be used as a screening tool for early detection and thus earlier management of this painful condition. Results from a small study from Iran suggest that hypertension has a detrimental effect on aortic wall elasticity and left ventricular function regardless of patient age, potentially making the patient more at risk of a cardiovascular event. Earlier detection may allow for prompt treatment, thus slowing disease progression. A timely article from Reeve et al. discusses the value of online journal clubs as a source of continuing professional development during a global pandemic. Online journal clubs allow international participation that traditional journal clubs could not. The article focuses specifically on the first BMUS journal club article from August 2020, which investigated professional practice in obstetrics.

Oxygen saturationmonitors were initially only used in anaesthesia and intensive care but are now available from supermarkets and are used for home monitoring of COVID-19. Ultrasound is following a similar path from a specialist investigation to common use in acute care. In the next 10 years, a handheld ultrasound device could be in every medical practitioner’s pocket. Previously, point-of-care lung ultrasound (LUS) was used in acute care for diagnosing causes of hypoxia and so when COVID-19 developed into a global pandemic there was great interest in LUS for this disease. Initial case series from China detailed the LUS findings in COVID-19 with bilateral patchy B-lines, peripheral consolidations and a lack of large effusions. Further studies into diagnostic accuracy and prognostic ability of LUS for COVID-19 were ongoing or awaiting publication. Despite the lack of firm data, it still was useful during the first wave in the UK due to limitations in other diagnostic tests. There was very limited availability of rapid molecular tests and delays of several days for reverse transcriptase polymerase chain reaction (RTPCR). Other imaging methods were limited by poor specificity for disease (chest radiograph) or practical limitations in moving highly infectious patients within the hospital (computed tomography). LUS had a unique advantage, as it could be performed at the bedside giving results within minutes allowing rapid triage and treatment. During the second wave, rapid molecular testing was available in many centres and the turn-around time for RTPCR was significantly reduced. LUS also played a role in the diagnosis of patients with negative molecular tests and high clinical suspicion, particularly as nasopharyngeal RTPCR is only about 70% sensitive. In addition, LUS was used to rule out other causes of hypoxia such as pleural effusion and cardiac failure which can present in tandem with COVID-19. LUS findings consistent with COVID-19 should be treated with caution in times with low prevalence, as false positive rates will be higher. As the pandemic subsides, LUS will still play a key role in diagnosing other causes of hypoxia. The experience learnt in COVID-19 will lead to more practitioners being familiar with LUS and in particular with sonographic findings of a viral pneumonitis. It is unknown whether LUS will be useful in management of long COVID and its advantages over CT imaging of instant results at the bedside are far less important in chronic disease. A lack of equipment and suitably skilled practitioners restrict the availability of point-of-care LUS in the UK. The Society for Acute Medicine and Intensive Care Society are working hard to address this through their established LUS training pathways, while handheld devices provide a cost-effective alternative to cart-based machines. LUS can provide rapid diagnosis of COVID-19 at the bedside and there is now clear evidence to su","PeriodicalId":23440,"journal":{"name":"Ultrasound","volume":"29 3","pages":"140"},"PeriodicalIF":0.8,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/1742271X211033737","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39451205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
