Inflammatory bowel disease (IBD) is due to aberrant responses of the gut mucosa to the resident microbiome.

This research looked at Crohn’s and Ulcerative Colitis (both types of IBD) to identify which immune cells are involved in IBD, and to help identify novel therapeutic targets.

We examined longer-term mortality in patients with dementia and SARS-CoV-2 infection. We found an increased mortality in patients with dementia beyond the acute phase of illness. We identified several investigation results associated with increased mortality, and increased mortality in patients prescribed antipsychotics or benzodiazepines.

Economic evidence for interventions in treatment-resistant depression is underdeveloped, particularly so for service-level interventions. Where evidence does exist, it is hampered by inconsistency in study design, methodological quality, and availability of high quality long-term outcomes evidence. This review identifies a number of key considerations and challenges for the design of future economic evaluations. Recommendations for research and suggestions for good practice are made.

Brain scans like PET enable the visualisation and quantification of brain inflammation, which is an important and common pathological feature in dementia. Using PET we found that high levels of inflammation in frontal brain regions in people with frontotemporal dementia is associated with faster decline in their thinking performance over time. Our results highlight the potential for immunomodulatory treatment strategies in frontotemporal dementia.

  • 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
without pre-amplification.

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.

Cambridge scientists have successfully trialled an artificial pancreas for use by patients living with type 2 diabetes. The device – powered by an algorithm developed at the University of Cambridge – doubled the amount of time patients were in the target range for glucose and halved the time spent experiencing high glucose levels.

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.

Increasing physical activity of any intensity is beneficial for health, but new research published in the European Heart Journal shows that there is a greater reduction in cardiovascular disease risk when more of that activity is of at least moderate intensity.

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.

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.

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.

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.

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.

Fiber structures and pathological features, e.g., inflammation and glycosaminoglycan (GAG) deposition, are the primary determinants of aortic mechanical properties which are associated with the development of an aneurysm. This study is designed to quantify the association of tissue ultimate strength and extensibility with the structural percentage of different components, in particular, GAG, and local fiber orientation.
