This case report highlights an unusual presentation of acute adrenal infarction in a Covid-19 patient who presented with abdominal symptoms and hyponatraemia. We discuss the recent literature reviewing how Covid-19 creates a hypercoaguable state, with acute adrenal infarction as a possible prothrombotic complication.
Superparamagnetic iron oxide nanoparticles (SPIONs) are an exciting advancement in the field of nanotechnology. They expand the possibilities of noninvasive analysis and have many useful properties, making them potential candidates for numerous novel applications. Notably, they have been shown that they can be tracked by magnetic resonance imaging (MRI) and are capable of conjugation with various cell types, including stem cells. In-depth research has been undertaken to establish these benefits, so that a deeper level of understanding of stem cell migratory pathways and differentiation, tumor migration, and improved drug delivery can be achieved. Stem cells have the ability to treat and cure many debilitating diseases with limited side effects, but a main problem that arises is in the noninvasive tracking and analysis of these stem cells. Recently, researchers have acknowledged the use of SPIONs for this purpose and have set out to establish suitable protocols for coating and attachment, so as to bring MRI tracking of SPION-labeled stem cells into common practice. This review paper explains the manner in which SPIONs are produced, conjugated, and tracked using MRI, as well as a discussion on their limitations. A concise summary of recently researched magnetic particle coatings is provided, and the effects of SPIONs on stem cells are evaluated, while animal and human studies investigating the role of SPIONs in stem cell tracking will be explored.
Background/Aims During the COVID-19 pandemic, inflammatory bowel disease clinics were converted to telephone clinics at St. Mark's Hospital in Harrow. This study assessed the response of patients and clinicians to remote telemedicine services, with the view of establishing whether there was scope for increasing the role of remote services in the inflammatory bowel disease clinics. Methods Clinicians administered a questionnaire to patients at the end of their appointments regarding their opinions on the telephone clinic format. Eleven questions used a 5-point Likert scale while a further three questions asked the patient for their comments on future clinics. Clinicians provided information about the patients' condition and management, as well as their own comments. Results Overall satisfaction with telephone clinics was found to be high among patients and clinicans, with many feeling that telephone clinics were more convenient. In total, 94.3% of patients said they would prefer either all telephone or a mix of phone and face-to-face clinics in the future. However, some patients felt that it was more complicated to have blood or stool tests done and roughly a quarter of patients were concerned that something could be missed without a physical examination. Conclusions High patient satisfaction can be achieved by delivering a mix of telephone, video and face-to-face clinics. In certain clinical situations, face-to-face clinics would be appropriate, such as patients with active diseases and first appointments. The pandemic is an opportunity respond to patients' preferences by increasing the range of remote care options.
Introduction
CONTACT is a national multidisciplinary study assessing the impact of the COVID-19 pandemic upon diagnostic and treatment pathways among patients with pancreatic ductal adenocarcinoma (PDAC).
Methods
The treatment of consecutive patients with newly diagnosed PDAC from a pre-COVID-19 pandemic cohort (07/01/2019-03/03/2019) were compared to a cohort diagnosed during the first wave of the UK pandemic (‘COVID’ cohort, 16/03/2020-10/05/2020), with 12-month follow-up.
Results
Among 984 patients (pre-COVID: n = 483, COVID: n = 501), the COVID cohort was less likely to receive staging investigations other than CT scanning (29.5% vs. 37.2%, p = 0.010). Among patients treated with curative intent, there was a reduction in the proportion of patients recommended surgery (54.5% vs. 76.6%, p = 0.001) and increase in the proportion recommended upfront chemotherapy (45.5% vs. 23.4%, p = 0.002). Among patients on a non-curative pathway, fewer patients were recommended (47.4% vs. 57.3%, p = 0.004) or received palliative anti-cancer therapy (20.5% vs. 26.5%, p = 0.045). Ultimately, fewer patients in the COVID cohort underwent surgical resection (6.4% vs. 9.3%, p = 0.036), whilst more patients received no anti-cancer treatment (69.3% vs. 59.2% p = 0.009). Despite these differences, there was no difference in median overall survival between the COVID and pre-COVID cohorts, (3.5 (IQR 2.8–4.1) vs. 4.4 (IQR 3.6–5.2) months, p = 0.093).
Conclusion
Pathways for patients with PDAC were significantly disrupted during the first wave of the COVID-19 pandemic, with fewer patients receiving standard treatments. However, no significant impact on survival was discerned.
