The Covid-19 crisis necessitated rapid adoption of remote consultations across National Health Service (NHS) child and adolescent mental health services (CAMHS).
This study aimed to understand practitioners’ experiences of rapid implementation of remote consultations across CAMHS in one NHS trust in the east of England.
Data were collected through a brief questionnaire documenting clinicians’ experiences following remote delivery of services. The questionnaire began before ‘lockdown’ and focused on 102 assessment consultations as part of a planned move to virtual assessment.
As the roll-out of remote consultations was extended at lockdown, the researchers extended the questionnaire to include all remote clinical contacts (n = 202).
Despite high levels of initial concern, clinicians’ reports were positive overall; importantly, however, their experiences varied by team. When restrictions on face-to-face working are lifted, a blended approach of remote and face-to-face service delivery is recommended to optimise access and capacity while retaining effective and safe care.View publication

- Time-series blood test & vital sign data from older inpatients were presented to HMM (Hidden Markov Models)
- Hidden clinically interpretable states were extracted, linked with diagnoses and death
- States modeled inpatient trajectories, differentiating risk from admission-discharge
- The clinical interpretation of HMM states helped explain how ML models organise data

Respiratory infections are the major cause of death from infectious disease worldwide. Multiplexed diagnostic approaches are essential as many respiratory viruses have indistinguishable symptoms.
We created self-assembled DNA nanobait that can simultaneously identify multiple short RNA targets. The nanobait approach relies on specific target selection via toehold-mediated strand displacement and rapid read-out via nanopore sensing. Here, we show this platform can concurrently identify several common respiratory viruses, detecting a panel of short targets of viral nucleic acids from multiple viruses.
Our nanobait can be easily reprogrammed to discriminate viral variants, as we demonstrated for several key SARS-CoV-2 variants with single-nucleotide resolution. Lastly, we show that nanobait discriminates
between samples extracted from oropharyngeal swabs from negative and positive SARS-CoV-2 patients
Our system allows for multiplexed identification of native RNA molecules, providing a new scalable approach for diagnostics of multiple respiratory viruses in a single assay.View publication

In a cohort of 187 people with schizophrenia treated with clozapine, we examined the relationship between clozapine, sedation, and aspects of symptoms: motivation/pleasure, and emotional expressivity. Clozapine was associated with increased sedation (a known side effect), and this sedation worsened motivation/pleasure; however, there was also a separate effect through which clozapine was directly associated with improved motivation/pleasure. These results highlight the important of addressing sedative side-effects of antipsychotic medications to improve quality of life.

Previous research has shown that people hospitalised with COVID-19 are at risk of weight loss and malnutrition. This study looked at patients who experienced weight loss of 10% or more during their hospital admission to Cambridge University Hospitals NHS with COVID-19 during the first wave of the pandemic. Weight loss of 10% or more is considered a large amount to lose as it increases the chance of someone becoming more poorly and not surviving. Therefore, preventing weight loss may help patients to survive and recover. The study looked at risk factors for weight loss to help better recognise the patients that need more support to prevent weight loss.View publication

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.View publication

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.View publication

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.View publication

Currently in the UK, women are selected for diagnostic testing for Gestational Diabetes Mellitus (GDM) based on risk factors such as obesity. Researchers developed a new predictive test for GDM using metabolomic markers from maternal serum samples, measured at multiple stages of pregnancy. The test was developed using samples from the Pregnancy Outcome Prediction (POP) study and it was externally validated in maternal plasma samples from a demographically highly dissimilar Born in Bradford (BiB) study. Further assessment in the POP study suggested that the predictive ability of a model including the metabolomic markers was clearly better compared to using early pregnancy obesity alone.View publication

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.View publication

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.View publication

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.View publication

Randomised trials of vitamin D supplementation for cardiovascular disease and all-cause mortality have generally reported null findings. However, generalisability of results to individuals with low vitamin D status is unclear. Researcgers aimed to characterise dose-response relationships between 25-hydroxyvitamin D (25[OH]D) concentrations and risk of coronary heart disease, stroke, and all-cause mortality in observational and Mendelian randomisation frameworks.View publication
