The Accuracy of Ultrasound Controlled Attenuation Parameter in Diagnosing Hepatic Fat Content.

Purpose: The Controlled Attenuation Parameter (CAP score) is based on ultrasonic properties of retropropagated radiofrequency signals acquired by Fibroscan (Echosens, Paris, France). Since ultrasound propagation is influenced by the presence of fat, CAP score was developed to quantify steatosis. The aim of this study was to delineate the accuracy of CAP in diagnosing hepatic steatosis, compared to the gold standard of liver biopsy.

Behaviour Change Techniques to promote self-management and home exercise adherence for people attending physiotherapy with musculoskeletal conditions: A scoping review and mapping exercise.

Background: Many patients with musculoskeletal problems do not adhere to home exercises or self-management advice provided by physiotherapists. This is due to numerus factors, many of which can be targeted by Behaviour Change Techniques.

Objectives: 1) Undertake a scoping review to identify the modifiable determinants (barriers and facilitators) of home exercise adherence and self-management for the physiotherapy management of people with musculoskeletal problems and map them to the Theoretical Domains Framework and Behaviour Change Techniques.

Litigation in thyroid surgery: a pan-specialty review of National Health Service (UK) data.

Objective: Thyroid surgery carries risks that significantly impact patients. This paper describes the landscape of thyroid surgery related litigation claims in the National Health Service from April 2015 to April 2020, to establish learning points in order to improve patient care and minimise litigation risk.

Methods: Data were requested from National Health Service Resolution and Hospital Episode Statistics.

Variants of the Anterior Subtemporal Approach to the Gasserian Ganglion and Related Structures: An Anatomical Study With Relevant Implications for Keyhole Surgery.

Background: The advantages and limitations of different craniotomy positions and approach trajectories to the gasserian ganglion (GG) and related structures using an anterior subtemporal approach have not been studied systematically. Knowledge of these features is of importance when planning keyhole anterior subtemporal (kAST) approaches to the GG to optimize access and minimize risks.

Methods: Eight formalin-fixed heads were used bilaterally to assess temporal lobe retraction (TLR), trigeminal exposure, and relevant anatomical aspects of extra- and transdural classic anterior subtemporal (CLAST) approaches compared with slightly dorsally and ventrally allocated corridors.

Betahistine Prescribing Practices in England: An Analysis of Prescribing and National Spending Pre- and Post-BEMED Trial.

Objective: Betahistine has not been proven to be superior to placebo in the BEMED study, a multicenter, double-blind, randomized, placebo controlled trial. Our study aimed to establish the prescribing practices of clinicians in England in relation to betahistine and to assess if there has been any change in prescribing practices since the publication of the BEMED trial.

Study Design: Retrospective study and clinician survey.

When to Consult a Geneticist Specialising in Gestational Trophoblastic Disease.

Background: Gestational trophoblastic disease comprises hydatidiform moles and a rare group of malignancies that derive from trophoblasts. Although there are typical morphological features that may distinguish hydatidiform moles from non-molar products of conception, such features are not always present, especially at early stages of pregnancy. Furthermore, mosaic/chimeric pregnancies and twin pregnancies make pathological diagnosis challenging while trophoblastic tumours can also pose diagnostic problems in terms of their gestational or non-gestational origin.

Mesenchymal Stem Cell in Pancreatic Islet Transplantation.

Pancreatic islet transplantation is a therapeutic option for achieving physiologic regulation of plasma glucose in Type 1 diabetic patients. At the same time, mesenchymal stem cells (MSCs) have demonstrated their potential in controlling graft rejection, the most fearsome complication in organ/tissue transplantation. MSCs can interact with innate and adaptive immune system cells either through direct cell-cell contact or through their secretome including exosomes.

Triaxial accelerometer-measured physical activity and functional behaviours among people with High Grade Glioma: The BrainWear Study.

Background: High-grade gliomas (HGG) account for 60-75% of all adult gliomas. The complexity of treatment, recovery and survivorship creates a need for novel monitoring approaches. Accurate assessment of physical function plays a vital role in clinical evaluation.

Giant cell arteritis presenting with unilateral sixth nerve palsy.

Giant cell arteritis (GCA) usually presents with headache, scalp tenderness and raised inflammatory markers. GCA presenting with a clinically evident cranial nerve palsy is rare and may result in a delayed or missed diagnosis if not suspected. We present the rare case of a woman in her 70s with histologically confirmed GCA presenting with a unilateral sixth nerve palsy, which responded to treatment with high-dose oral prednisolone.

Radiomics and artificial intelligence for precision medicine in lung cancer treatment.

Lung cancer is the leading cause of cancer-related deaths worldwide. It exhibits, at the mesoscopic scale, phenotypic characteristics that are generally indiscernible to the human eye but can be captured non-invasively on medical imaging as radiomic features, which can form a high dimensional data space amenable to machine learning. Radiomic features can be harnessed and used in an artificial intelligence paradigm to risk stratify patients, and predict for histological and molecular findings, and clinical outcome measures, thereby facilitating precision medicine for improving patient care.

Time course of neuroinflammation after human stroke - a pilot study using co-registered PET and MRI.

Background: Microglial activation contributes to both inflammatory damage and repair in experimental ischemic stroke. However, because of the logistical challenges, there have been few clinical imaging studies directly describing inflammatory activation and its resolution after stroke. The purpose of our pilot study was to describe the spatio-temporal profile of brain inflammation after stroke using 18kD translocator protein (TSPO) positron emission tomography (PET) with magnetic resonance (MR) co-registration in the subacute and chronic stage after stroke.

Analytical variation concerning total 25-hydroxyvitamin D measurement, where are we now? A DEQAS review of current assay performance.

The Vitamin D External Quality Assessment Scheme (DEQAS) distributes serum samples globally, on a quarterly basis, to assess participants' performance of specific methods for 25-hydroxyvitamin D (25OHD) and other vitamin D metabolites. In this review an assessment of the state of the art in the performance of 25OHD methods is presented. This assessment is based on an analysis of data submitted by scheme participants for the 2021/22 distribution cycle, which comprised of four distributions each containing five DEQAS samples.

Optimising trajectory planning for stereotactic brain tumour biopsy using artificial intelligence: a systematic review of the literature.

Purpose: Despite advances in technology, stereotactic brain tumour biopsy remains challenging due to the risk of injury to critical structures. Indeed, choosing the correct trajectory remains essential to patient safety. Artificial intelligence can be used to perform automated trajectory planning.

Effects of Opioids on Immune and Endocrine Function in Patients with Cancer Pain.

Opioids are an important treatment in managing cancer pain. Uncontrolled pain can be detrimental to function and quality of life. Common adverse effects of opioids such as sedation, constipation and nausea are well recognised, but opioid effects on the endocrine and immune systems are less apparent.

REFINE-Lung implements a novel multi-arm randomised trial design to address possible immunotherapy overtreatment.

Increasing evidence suggests that some immunotherapy dosing regimens for patients with advanced cancer could result in overtreatment. Given the high costs of these agents, and important implications for quality of life and toxicity, new approaches are needed to identify and reduce unnecessary treatment. Conventional two-arm non-inferiority designs are inefficient in this context because they require large numbers of patients to explore a single alternative to the standard of care.

A UK consensus statement on thromboprophylaxis for autologous breast reconstruction.

Unlabelled: Microsurgical breast reconstruction accounts for 22% of breast reconstructions in the UK. Despite thromboprophylaxis, venous thromboembolism (VTE) occurs in up to 4% of cases. Using a Delphi process, this study established a UK consensus on VTE prophylaxis strategy, for patients undergoing autologous breast reconstruction using free-tissue transfer.

Non-crystalline light chain proximal tubulopathy, a morphologically protean entity.

Background: Light chain proximal tubulopathy (LCPT) is a rare form of paraprotein-related disease, occurring in two main histopathological forms: crystalline and non-crystalline. The clinicopathological features, treatment strategies and outcomes, especially of the non-crystalline form, are not well described.

Methods: We conducted a single-centre retrospective case series of 12 LCPT patients, 5 crystalline and 7 non-crystalline, between 2005 and 2021.

Autoimmune encephalitis: recent clinical and biological advances.

In 2015, we wrote a review in The Journal of Neurology summarizing the field of autoantibody-associated neurological diseases. Now, in 2023, we present an update of the subject which reflects the rapid expansion and refinement of associated clinical phenotypes, further autoantibody discoveries, and a more detailed understanding of immunological and neurobiological pathophysiological pathways which mediate these diseases. Increasing awareness around distinctive aspects of their clinical phenotypes has been a key driver in providing clinicians with a better understanding as to how these diseases are best recognized.
