Cerebral perfusion alterations in healthy young adults due to two genetic risk factors of Alzheimer's disease: APOE and MAPT.

J Cereb Blood Flow Metab

January 2025

Sheffield Institute for Translational Neuroscience, Division of Neuroscience, School of Medicine and Population Heath, University of Sheffield, Sheffield, UK.

Functional brain changes such as altered cerebral blood flow occur long before the onset of clinical symptoms in Alzheimer's disease (AD) and other neurodegenerative disorders. While cerebral hypoperfusion occurs in established AD, middle-aged carriers of genetic risk factors for AD, including APOE ε4, display regional hyperperfusion due to hypothesised pleiotropic or compensatory effects, representing a possible early biomarker of AD and facilitating earlier AD diagnosis. However, it is not clear whether hyperperfusion already exists even earlier in life.

Background The sentinel lymph node biopsy (SLNB) is the standard method used to determine the stage of breast cancer in patients with no clinical signs of axillary involvement. The current gold standard for the intraoperative assessment of the axilla involves the use of dual radioisotope and patent blue dye. However, researchers have been studying the use of superparamagnetic iron oxide Magtrace® (Endomagnetics Limited, Cambridge, United Kingdom) agents as an alternative to overcome the limitations of the standard SLNB technique.

Pharmacotherapeutic options for coronary thrombosis treatment: where are we today?

Expert Opin Pharmacother

January 2025

Cardiovascular Research Unit, Division of Clinical Medicine, School of Medicine and Population Health, University of Sheffield, Sheffield, UK.

Introduction: Advances in pharmacotherapy for coronary thrombosis treatment and prevention have transformed the clinical outcomes of patients with coronary artery disease but increased the complexity of therapeutic decision-making. Improvements in percutaneous coronary intervention techniques and stent design have reduced the incidence of thrombotic complications, which consequently has increased the challenge of adequately powering clinical trials of novel antithrombotic strategies for efficacy outcomes. Knowledge of the pathophysiology of coronary thrombosis and the characteristics of antithrombotic drugs can help with therapeutic decisions.

Background: Interviewers' judgements play a critical role in competency-based assessments for selection such as the multiple-mini-interview (MMI). Much of the published research focuses on the psychometrics of selection and the impact of rater subjectivity. Within the context of selecting for entry into specialty postgraduate training, we used an interpretivist and socio-constructivist approach to explore how and why interviewers make judgments in high stakes selection settings whilst taking part in an MMI.

Cyclin O controls entry into the cell-cycle variant required for multiciliated cell differentiation.

Cell Rep

January 2025

Institut de Biologie de l'ENS (IBENS), CNRS, INSERM, Ecole Normale Supérieure, PSL Research University, Paris, France. Electronic address:

Multiciliated cells (MCCs) ensure fluid circulation in various organs. Their differentiation is marked by the amplification of cilia-nucleating centrioles, driven by a genuine cell-cycle variant, which is characterized by wave-like expression of canonical and non-canonical cyclins such as Cyclin O (CCNO). Patients with CCNO mutations exhibit a subtype of primary ciliary dyskinesia called reduced generation of motile cilia (RGMC).

Next generation brain health: transforming global research and public health to promote prevention of dementia and reduce its risk in young adult populations.

Lancet Healthy Longev

December 2024

Global Brain Health Institute (GBHI), Trinity College Dublin, Dublin, Ireland; Centre for Dementia Research, School of Health, Leeds Beckett University, Leeds, UK.

Efforts to prevent dementia can benefit from precision interventions delivered to the right population at the right time; that is, when the potential to reduce risk is the highest. Young adults (aged 18-39 years) are a neglected population in dementia research and policy making despite being highly exposed to several known modifiable risk factors. The risk and protective factors that have the biggest effect on dementia outcomes in young adulthood, and how these associations differ across regions and groups, still remain unclear.

Clinical Utility of Bone Turnover Markers in Chronic Kidney Disease.

J Bone Metab

November 2024

Division of Clinical Medicine, School of Medicine and Population Health, University of Sheffield, Sheffield, UK.

Chronic kidney disease (CKD) often leads to mineral and bone disorders (CKD-MBDs), which are nearly universal in patients undergoing dialysis. CKD-MBD includes abnormal calcium-phosphate metabolism, vascular and soft tissue calcification, and bone abnormalities (renal osteodystrophy [ROD]). Bone fragility in CKD occurs due to low bone mass and poor bone quality, and patients with CKD have higher fracture and mortality rates.
