Summary

COVID-19 is associated with neurological complications including stroke, delirium and encephalitis. Furthermore, a post-viral syndrome dominated by neuropsychiatric symptoms is common, and is seemingly unrelated to COVID-19 severity. The true frequency and underlying mechanisms of neurological injury are unknown, but exaggerated host inflammatory responses appear to be a key driver of COVID-19 severity.

Researchers investigated the dynamics of, and relationship between, serum markers of brain injury (neurofilament light [NfL], glial fibrillary acidic protein [GFAP] and total tau) and markers of dysregulated host response (autoantibody production and cytokine profiles) in 175 patients admitted with COVID-19 and 45 patients with influenza.

Summary

The renin-angiotensin-aldosterone system (RAAS) is of interest in understanding COVID-19. Using data extracted from CUH Epic, researchers observed profoundly low aldosterone levels (measured using gold-standard mass-spectrometry) in a large proportion of patients with COVID-19, which were not anticipated. The mechanism of this reduction remains obscure with no obvious correlation with obvious explanations. The profoundly low levels have likely not been detected previously since previous studies used immunoassays to measure aldosterone, in which there are high levels of interference in patients with COVID-19.

Summary

Assessing frailty in hospital patients is important but it is not clear how best to assess it. Researchers compared two options: the modified Frailty Index [mFI] and the Clinical Frailty Scale [CFS], and assessed how useful each were for predicting death in older adults (≥65 years) in hospital with COVID-19.  Our  work suggests the CFS is better than mFI at predicting death in patients who have COVID-19.

Summary

DNA damage caused by factors such as ultraviolet radiation affect nearly three-quarters of all stem cell lines derived from human skin cells, say Cambridge researchers, who argue that whole genome sequencing is essential for confirming if cell lines are usable. Read the full news story.

Summary

Synaptic loss occurs early in many neurodegenerative diseases and contributes to cognitive impairment even in the absence of gross atrophy. Currently, for human disease there are few formal models to explain how cortical networks underlying cognition are affected by synaptic loss. Researchers advocate that biophysical models of neurophysiology offer both a bridge from clinical to preclinical models of pathology, and quantitative assays for experimental medicine.

Summary

An international team of researchers has modelled the impact that increasing treatment capacity and using a quicker, less invasive treatment option would have on waiting lists. Even in the best-case scenario, they found that the waiting list would take nearly a year to clear.

The traditional treatment for aortic stenosis involves replacing the narrowed valve, most commonly through open heart surgery (a surgical aortic valve replacement, SAVR). However, a newer keyhole procedure called a transcatheter aortic valve implantation (TAVI) is increasingly being used and is now recommended for patients aged 75 and over.

The researchers investigated the impact that increasing treatment capacity and converting a proportion of operations to the quicker TAVI procedure would have on the backlog. They looked at how long it would take to clear the backlog and found that the best and most achievable option involved a combination of increasing capacity by 20 per cent and converting 40 per cent of procedures from SAVR to TAVI. This would clear the backlog within 343 days with 784 deaths while people wait for treatment. Read the full story.

Summary

Placental function and dysfunction differ by sex but the mechanisms are unknown. Researchers show that sex differences in polyamine metabolism are associated with escape from X chromosome inactivation of the gene encoding spermine synthase (SMS).

Summary

The quality of a child’s social and physical environment is a key influence on brain development, educational attainment and mental wellbeing. However, there still remains a mechanistic gap in our understanding of how environmental influences converge on changes in the brain’s developmental trajectory. In a sample of 145 children with structural diffusion tensor imaging data, researchers used generative network modelling to simulate the emergence of whole brain network organisation.

Summary

Artificial intelligence (AI) is increasingly taking on a greater role in healthcare. However, hype and negative news reports about AI abound. Integrating patient and public involvement (PPI) in healthcare AI projects may help in adoption and acceptance of these technologies. Researchers argue that AI algorithms should also be co-designed with patients and healthcare workers. They specifically suggest (1) including patients with lived experience of the disease, and (2) creating a research advisory group (RAG) and using these group meetings to walk patients through the process of AI model building, starting with simple (e.g., linear) models.

Since 2008, the Government in the United Kingdom has funded a large, annual survey called the National Diet and Nutrition Survey Rolling Programme (NDNS RP) to collect detailed information from people on the foods they are eating and their nutritional health.

The survey is used to monitor how well the UK population is doing in terms of dietary guidelines and inform the development of new nutrition policies. It is also used to monitor chemical exposure risk to protect food safety. In this NIHR Cambridge BRC paper, the authors have provided easy access to comprehensive information about the NDNS for the academic and wider public health community.

The paper describes the data collected in the first 11 years of the NDNS RP, how it has been used, and demonstrates the scope of publicly available data. The authors present an overview of survey methods to collect and analyse the data.

Between 2008 and 2019, 7999 adults and 7656 children completed food diaries; 4181 adults and 2014 children had a blood sample taken; 3246 adults and 2318 children gave a urine sample and 419 adults and 352 children had their energy expenditure measured. The authors explain how NDNS survey reports and data provide information on the foods, calories and nutrients such as fat, sugar and vitamins consumed by the UK population, and how Government use these data in public health campaigns such as the Change4Life, 5 A DAY and sugar reduction and folate fortification policies.

They also highlight that many other institutions and individuals use the survey including international organisations like the World Health Organisation. Reports are published regularly by Government: https://www.gov.uk/government/collections/national-diet-and-nutrition-survey. Anonymised individual data can be accessed from the Data Service and stored blood and urine samples are available for further research via the NDNS Bioresource.

The NDNS RP provides a unique and valuable publicly available resource for the UK Government, researchers, health professionals and others looking to understand and improve population health and nutrition.
