Item Not all knees are the same(British Editorial Society of Bone and Joint Journal, 2024-06-01) MacDessi, S. J.; van de Graaf, V. A.; Wood, J. A.; Griffiths-Jones, W.; Bellemans, J.; Chen, D. B.The aim of mechanical alignment in total knee arthroplasty is to align all knees into a fixed neutral position, even though not all knees are the same. As a result, mechanical alignment often alters a patient's constitutional alignment and joint line obliquity, resulting in soft-tissue imbalance. This annotation provides an overview of how the Coronal Plane Alignment of the Knee (CPAK) classification can be used to predict imbalance with mechanical alignment, and then offers practical guidance for bone balancing, minimizing the need for soft-tissue releases.Item Digital tools in cardiac reperfusion pathways: A systematic review(HighWire, 2024-03-01) Chhatwal, K.; Deighton, A.; Dhir, A.; Kumar, V. V.; Titus-Glover, S.; Shah, D.; Holt, L.With health and surgery increasingly aided by digital technologies, there exists a growing impetus to understand how such tools must integrate into existing clinical pathways to ensure a positive impact on patient and organisational outcomes. Consequently, this study sought to collate evidence on the use of digital technology in cardiac reperfusion surgeries. We systematically searched three scientific databases for relevant articles. In total, 1,092 articles were retrieved, with 126 screened using inclusion/exclusion criteria, and 21 selected for analysis. Articles reported on the use of virtual reality, mHealth and telehealth in cardiovascular reperfusion procedures, ranging from surgical training regimens to postoperative rehabilitation. Here, despite clinical advantages, limitations were highlighted, including cost, ineffective interfaces and extensive training needed to operate novel digital tools. Nevertheless with further development and input from patient stakeholders, many limitations look set to dematerialise and provide tangible improvements to the benefit of patients and hard-pressed health institutions.Item Adenylyl Cyclase in Ocular Health and Disease: A Comprehensive Review(MDPI, 2024-06-01) Thompson, P.; Vilkelyte, V.; Woronkowicz, M.; Tavakoli, M.; Skopinski, P.; Roberts, H.Adenylyl cyclases (ACs) are a group of enzymes that convert adenosine-5'-triphosphate (ATP) to cyclic adenosine 3',5' monophosphate (cAMP), a vital and ubiquitous signalling molecule in cellular responses to hormones and neurotransmitters. There are nine transmembrane (tmAC) forms, which have been widely studied; however, the tenth, soluble AC (sAC) is less extensively characterised. The eye is one of the most metabolically active sites in the body, where sAC has been found in abundance, making it a target for novel therapeutics and biomarking. In the cornea, AC plays a role in endothelial cell function, which is vital in maintaining stromal dehydration, and therefore, clarity. In the retina, AC has been implicated in axon cell growth and survival. As these cells are irreversibly damaged in glaucoma and injury, this molecule may provide focus for future therapies. Another potential area for glaucoma management is the source of aqueous humour production, the ciliary body, where AC has also been identified. Furthering the understanding of lacrimal gland function is vital in managing dry eye disease, a common and debilitating condition. sAC has been linked to tear production and could serve as a therapeutic target. Overall, ACs are an exciting area of study in ocular health, offering multiple avenues for future medical therapies and diagnostics. This review paper explores the diverse roles of ACs in the eye and their potential as targets for innovative treatments.Item Laboratory practice is central to earlier myeloma diagnosis: Utilizing a primary care diagnostic tool and laboratory guidelines integrated into haematology services(Wiley, 2024-02-01) Drayson, M.; Jennis, T.; Laketic-Ljubojevic, I.; Patel, D.; Pratt, G.; Renwick, S.; Richter, A.; Wheeler, R.; Sheldon, J.; Sadler, R.; Stapleton, M.; Willis, F.; Whiston, M.Treatment advances have greatly improved survival, but myeloma is among the worst of all cancers for delayed diagnosis, causing serious morbidities and early deaths. This delay is largely because the symptom profile of myeloma has very low specificity, and in primary care, myeloma is rare. However, initiating the journey to diagnosis simply requires considering myeloma and sending blood to test for monoclonal immunoglobulin. Laboratory tests reliably detect monoclonal immunoglobulin, which is present in 99% of myeloma cases, so why do health care systems have such a problem with delayed diagnosis? The Myeloma UK early diagnosis programme has brought together diverse expertise to investigate this problem, and this article was prepared by the programme's working group for laboratory best practice. It reviews evidence for test requesting, analysis and reporting, for which there is large variation in practice across the United Kingdom. It presents a 'GP Myeloma diagnostic tool' and how it can be integrated into laboratory practice alongside a laboratory best practice tool. It proposes improved requesting and integration with haematology services for reporting and interpretation. Here the laboratory has a central role in creating efficient and cost-effective pathways for appropriate and timely bone marrow examination for myeloma diagnosis.Item Cochlear implant referral patterns in the UK suggest a postcode lottery with inequitable access for older adults; results of a pilot audit in five Audiology sites(Taylor and Francis Group, NYP) Cullington, H.; Dickinson, A. M.; Martinez de Estibariz, U.; Blackaby, J.; Kennedy, L.; McNeill, K.; O'Neill, S.OBJECTIVE: To use a standardised reporting tool to identify potential eligible candidates for cochlear implant (CI) referral and quantify the proportion of adults who had a CI referral discussion after presenting with an audiogram within United Kingdom (UK) audiometric criteria. DESIGN: Retrospective multicentre 6-month audit of Audiology clinic databases. STUDY SAMPLE: A total of 810 adults from five geographically diverse UK Audiology sites. RESULTS: Data were collected in late 2019 after UK CI audiometric candidacy criteria changed; one site collected only 3 months of data. The proportion of potential eligible adults (based only on audiometry) considered for CI referral was 64% (521 out of 810) and varied by site (from 50% to 83%). About 24% of patients (123 out of 521) declined CI referral; this also varied across sites (12-45%). The median age of patients where CI referral was not considered was 80 years - significantly higher than the group where CI referral was considered (73 years). CONCLUSIONS: CI referral is dependent on where adults live, and how old they are. Older adults are significantly less likely to be considered for CI referral by Audiologists. Audiology clinics need more support to empower staff to talk to patients about CI referral.
