Abstract:The Wessex Classification Scheme was created by healthcare librarians in the South West of England, and was loosely based on the US National Library of Medicine classification. The scheme is widely used in healthcare libraries across the UK, both inside and outside the NHS. Although the scheme has gone through several revisions, there has been no major update since 2015, so the Wessex Classification Scheme Oversight Group was formed in September 2022 with the support of NHS England. The group aims to bring knowledge and skills from UK health library networks to improve the scheme, and also offers a chance for participants to develop skills in working with classification and subject indexing, and the opportunity to network widely. By forming a working group, it ensures the longevity of the scheme and shares the maintenance work more widely. Initially, members were asked which parts of the scheme they felt needed updating the most and sub-groups were formed for LGBTQ+ issues and gender identity (the Pride sub-group), Ethnicity and Race, and Learning Disability and Neurodiversity (the LDN sub-group) as well as a smaller team working on ‘quick and simple’ updates. The Pride sub-group undertook a review of the terminology and classification of items relating to the LGBTQ+ community, gender identity and gender affirming care and found that there were terms within the Wessex Classification Scheme that were no longer used or could be considered offensive, derogatory, or prejudicial. As a result of the review some terms were proposed to be removed completely (e.g. ‘hermaphroditism’) and other terms to be updated (e.g. ‘gender affirming surgery’ rather than ‘transsexual surgery’) using the Homosaurus as a guide in some cases. As part of the process, it was found that certain psychiatric topics were located within the same section as topics relating to sexual orientation and gender diversity. The sub-group believed this perpetuated a stereotype by linking these topics (e.g. paedophilia and incest) and so these were suggested to move from HQ to WM in the classification system. The Pride sub-group is committed to ensuring that the terms relating to the LGBTQ+ community are relevant and inclusive. Work by the Ethnicity and Race sub-group revealed terms within the Wessex subject index that were either outdated, problematic or more appropriate to a North American context than to a UK one. In addition to terms used to describe ethnic groups, related topics such as immigration, traditional medicine, homelessness and health inequalities were also considered. Appropriate sources of information were identified, and terms discussed, before making recommendations to the oversight group. The Learning Disabilities and Neurodiversity (LDN) sub-group is also looking at the language used in the subject index, and considering some broader changes to the classification schedules to bring together topics that are currently shelved in disparate areas of the classification. Some members of the LDN sub-group have lived experience of neurodiversity and are able to bring their experience to the work of the sub-group.

Abstract:
A 51-year-old lady with a background of rheumatoid arthritis presented to the foot and ankle clinic with pain and a typical history of Morton's neuroma. Examination revealed a palpable swelling over the right foot in the third intermetatarsal space. Following failed conservative management, the patient underwent excision of the neuroma. Histology revealed of necrotizing granulomas with peripheral palisading and no evidence of features specific to a neuroma. This has rarely been described previously and supports the concept of rheumatoid synovitis and nodules producing symptoms mimicking Morton's neuroma/metatarsalgia

Abstract:
Inconsistencies are evident within the literature regarding the role of Green Tea (GT) supplementation on women living with obesity. To address this, we conducted to determine the impact of GT supplementation on the weight, body mass index (BMI), and waist circumference (WC) in overweight and obese women using time and dose-response meta-analysis of randomized controlled trials (RCTs). This meta-analysis searched electronic Scopus, Web of Science, Embase, and PubMed/Medline databases from inception to December 1st, 2022. Data were reported as weighted mean difference (WMD) with 95% confidence interval (CI). A total of 2061 references were identified, and 15 articles with 16 RCT arms on body weight, 17 RCT arms on BMI, and 7 RCT arms on WC were included in the meta-analysis. GT supplementation significantly decreases body weight (WMD: -1.23 kg, 95% CI: -2.13 to -0.33, p = 0.007), BMI (WMD: -0.47 kg/m2, 95% CI: -0.87 to -0.07, p = 0.020) and WC (WMD: -3.46 cm, 95% CI: -6.75 to -0.16, p = 0.040). In subgroup analyses, GT consumption demonstrated lowered body weight with dosaes >=1000 mg/day (WMD: -1.38 kg), in the RCTs, which lasted >=8 wk (WMD: -1.24 kg). The non-linear dose-response assessment detected a negative correlation between the changes in body weight and BMI in green tea consumption of more than 1000 (mg/day). The GT supplementation reduced the weight, BMI, and WC in overweight and obese women. In clinical practice, healthcare professionals can recommend using GT with dosages >= 1000mg/day and duration >= 8 wk in obese women.

Abstract:
A 77-year old female with a history of neurofibromatosis type 2 (NF2) was diagnosed with a spinal schwannoma that was managed conservatively over a decade. During this time, follow up imaging revealed this lesion had been growing and the patient had become symptomatic from it necessitating surgical decompression. However, the patient had been diagnosed with multiple myeloma and underwent treatment with Pomalidomide chemotherapy which delayed surgery for the spinal schwannoma. Further imaging of the spine revealed significant regression in the size of the spinal schwannoma. This phenomenon has not peviously been reported and this report aims to explore the implications of Pomalidomide in patients with NF2 related spinal schwannomas.

Abstract:
BACKGROUND Open fractures of the ankle are complex injuries requiring multidisciplinary input and are associated with significant morbidity and mortality. However, data on the clinical outcomes of open ankle fracture management in patients older than 70 is minimal. AIM To evaluate the clinical outcomes following open ankle fracture management in patients older than 70. Our secondary aim is to look at predictors of poor outcomes. METHODS Following local research and audit department registration, 22 years of prospectively collated data from an electronic database in a district general hospital were assessed. All patients older than 70 years of age with an open ankle fracture requiring surgical intervention were identified. Demographic information, the nature, and the number of surgical interventions were collated. Complications, including surgical site infection (SSI), venous thromboembolic events (VTEs) during hospital stay, and mortality rate, were reviewed. RESULTS A total of 37 patients were identified (median age: 84 years, range: 70-98); n = 30 females median age: 84 years, range: 70-97); n = 7 males median age: 74 years, range: 71-98)) who underwent surgical intervention after an open ankle fracture. Sixteen patients developed SSIs (43%). Superficial SSIs (n = 8) were managed without surgical intervention and treated with antibiotics and regular dressing changes. Deep SSIs (n = 8; 20%) required a median of 3 (range: 2-9) surgical interventions, with four patients requiring multiple washouts and one patient having metalwork removed. VTE incidence was 5% during the hospital stay. Eight patients died within 30 d, and mortality at one year was 19%. The 10-year mortality rate was 57%. The presence of a history of stroke, cancer, or prolonged inpatient stay was found to be predictive of lower survivorship in this population (log-rank test: cancer P = 0.008, stroke P = 0.001, length of stay > 33 d P = 0.015). The presence of a cardiac history was predictive of wound complications (logistic regression, P = 0.045). Age, number of operations, and diabetic history were found to be predictive of an increase in the length of stay (general linear model; age P < 0.001, number of operations P < 0.001, diabetes P = 0.041). CONCLUSION An open ankle fracture in a patient older than 70 years has at least a 20% chance of requiring repeated surgical intervention due to deep SSIs. The presence of a cardiac history appears to be the main predictor for wound complications.

Abstract:
Background: Traumatic Spinal Cord Injury (TSCI) remains a significant cause of morbidity and mortality in humans. Magnetic Resonance Imaging (MRI) has been a spectacular modality in management, however, data correlating MRI findings with pathological insults in the hyperacute time-frame (i.e., within one hour of injury) is limited. This is due to the time-period between injury and transport to hospital is typically one-hour or more. Only after assessment and stabilization can an MRI be completed. In this context, nonhuman primate models are essential to provide insights into this critical scientific hypothesis. Method(s): The subject was a Rhesus macaque. Baseline MRI imaging of the spine was obtained. A small laminotomy was performed at L5 level and an epidural balloon catheter was advanced to the level of the lower thoracic spine which was inflated rapidly and remained for one-hour to produce lesions consistent with TSCI. MRI imaging, with and without contrast, was obtained over the next hour. Subsequently, the subject was humanely euthanized and a post-mortem examination was conducted. Tissue sections were collected from the epicenter, caudal and cephalad sites of the lesion. Result(s): The abnormalities were most prominent with Disco- Lava sequence MRI Technique. Sagittal images of the thoracic spine displayed increased abnormalities including increased signal intensity. The findings were consistent with edema and/or hemorrhage. Histology of coronal sections at the level of injury revealed focally extensive disruption of grey matter and central canal with marked grey matter hemorrhage, acute necrosis, and mild multifocal white matter hemorrhage. Eosinophilic material and erythrocytes were found in adjacent sections, up to 2 cm caudal to the lesion. Conclusion(s): MRI abnormalities were present within one hour after injury in acute experimental spinal cord injury. The histopathological findings are consistent with the radiological abnormalities.

Abstract:
Background: Pre-clinical models demonstrate that platelet activation is involved in the spread of malignancy. Ongoing clinical trials are assessing whether aspirin, which inhibits platelet activation, can prevent or delay metastases. Method(s): Urinary 11-dehydro-thromboxane B2(U-TXM), a biomarker of in vivo platelet activation, was measured after radical cancer therapy and correlated with patient demographics, tumour type, recent treatment, and aspirin use (100 mg, 300 mg or placebo daily) using multivariable linear regression models with log-transformed values. Result(s): In total, 716 patients (breast 260, colorectal 192, gastro-oesophageal 53, prostate 211) median age 61 years, 50% male were studied. Baseline median U-TXM were breast 782; colorectal 1060; gastro-oesophageal 1675 and prostate 826 pg/mg creatinine; higher than healthy individuals (~500 pg/mg creatinine). Higher levels were associated with raised body mass index, inflammatory markers, and in the colorectal and gastro-oesophageal participants compared to breast participants (P < 0.001) independent of other baseline characteristics. Aspirin 100 mg daily decreased U-TXM similarly across all tumour types (median reductions: 77-82%). Aspirin 300 mg daily provided no additional suppression of U-TXM compared with 100 mg. Conclusion(s): Persistently increased thromboxane biosynthesis was detected after radical cancer therapy, particularly in colorectal and gastro-oesophageal patients. Thromboxane biosynthesis should be explored further as a biomarker of active malignancy and may identify patients likely to benefit from aspirin.

Abstract:
Craniofacial osteosarcoma accounts for 10% of osteosarcoma malignancies, typically affecting the 4-5th decade of life, with the maxilla being the second-most common site. We report a 58-year-old male, non-smoker, with a lump of his upper jaw which occasionally bled during mastication. Clinical examination revealed an exophytic mass in the upper left tuberosity of the maxilla and no lymphadenopathy, where initial differential diagnosis was squamous cell carcinoma. Radiological investigations revealed a metabolically active left maxillary lesion with maxillary sinus destruction, representing primary malignancy. Histological analyses initially suggested a fibro-osseous lesion; further immunohistochemistry showed cytokeratin AE1/AE3/CK(MNF.116) positivity with 60% ki67 proliferation index; diagnostic of grade 2-3 osteosarcoma. Management included neoadjuvant chemotherapy prior to total maxillectomy and dental prosthetic rehabilitation. We report a novel case of primary osteosarcoma of the maxilla in an adult. Osteosarcoma is challenging to diagnose and an important differential to consider where the mainstay of treatment is early invention.

Abstract:
BACKGROUND: Most newly diagnosed oropharyngeal and hypopharyngeal cancers are treated with chemoradiotherapy with curative intent but at the consequence of adverse effects on quality of life. We aimed to investigate if dysphagia-optimised intensity-modulated radiotherapy (DO-IMRT) reduced radiation dose to the dysphagia and aspiration related structures and improved swallowing function compared with standard IMRT. METHOD(S): DARS was a parallel-group, phase 3, multicentre, randomised, controlled trial done in 22 radiotherapy centres in Ireland and the UK. Participants were aged 18 years and older, had T1-4, N0-3, M0 oropharyngeal or hypopharyngeal cancer, a WHO performance status of 0 or 1, and no pre-existing swallowing dysfunction. Participants were centrally randomly assigned (1:1) using a minimisation algorithm (balancing factors: centre, chemotherapy use, tumour type, American Joint Committee on Cancer tumour stage) to receive DO-IMRT or standard IMRT. Participants and speech language therapists were masked to treatment allocation. Radiotherapy was given in 30 fractions over 6 weeks. Dose was 65 Gy to primary and nodal tumour and 54 Gy to remaining pharyngeal subsite and nodal areas at risk of microscopic disease. For DO-IMRT, the volume of the superior and middle pharyngeal constrictor muscle or inferior pharyngeal constrictor muscle lying outside the high-dose target volume had a mandatory 50 Gy mean dose constraint. The primary endpoint was MD Anderson Dysphagia Inventory (MDADI) composite score 12 months after radiotherapy, analysed in the modified intention-to-treat population that included only patients who completed a 12-month assessment; safety was assessed in all randomly assigned patients who received at least one fraction of radiotherapy. The study is registered with the ISRCTN registry, ISRCTN25458988, and is complete. FINDINGS: From June 24, 2016, to April 27, 2018, 118 patients were registered, 112 of whom were randomly assigned (56 to each treatment group). 22 (20%) participants were female and 90 (80%) were male; median age was 57 years (IQR 52-62). Median follow-up was 39.5 months (IQR 37.8-50.0). Patients in the DO-IMRT group had significantly higher MDADI composite scores at 12 months than patients in the standard IMRT group (mean score 77.7 [SD 16.1] vs 70.6 [17.3]; mean difference 7.2 [95% CI 0.4-13.9]; p=0.037). 25 serious adverse events (16 serious adverse events assessed as unrelated to study treatment [nine in the DO-IMRT group and seven in the standard IMRT group] and nine serious adverse reactions [two vs seven]) were reported in 23 patients. The most common grade 3-4 late adverse events were hearing impairment (nine [16%] of 55 in the DO-IMRT group vs seven [13%] of 55 in the standard IMRT group), dry mouth (three [5%] vs eight [15%]), and dysphagia (three [5%] vs eight [15%]). There were no treatment-related deaths. INTERPRETATION: Our findings suggest that DO-IMRT improves patient-reported swallowing function compared with standard IMRT. DO-IMRT should be considered a new standard of care for patients receiving radiotherapy for pharyngeal cancers. FUNDING: Cancer Research UK.

Abstract:
BACKGROUND: The U grading of Ultrasound scan (USS) is used to assess the likelihood of malignancy in a thyroid nodule and help determine those that warrant an FNAC confirmation. All those of a U3-5 warrant an FNAC for confirmation and typing. This study aims to review the follow-up practice and the likelihood of picking up a malignancy on subsequent USS and FNAC, for those determined as an indeterminate U3 nodule. METHOD(S): We retrospective reviewed the trust database (Portal) for patients who had a U3 nodule reported on USS identified, and clinical, operative and outcomes data were analysed. RESULT(S): 258 scans were identified over a 5-year period. The average age was 59 (range 15- 95) years old at first USS with a female to the male sex ratio of 4:1. The average number of USS that each patient prior to final diagnosis had averaged at 2.8 (range 1-12). Of those with an initial Thy status, 64 (33%) were benign (Thy2) and a further 49 (25%) were non diagnostics (Thy1). Over time, only 7 nodules were upgraded to a potential malignancy. Of those who underwent surgery, a final histological diagnosis was obtained in 41 cases. Only Thy1, 2 and 3f produced benign final histology results. CONCLUSION(S): For those indeterminate (U3) nodules of Th1-3f, electing for a watch and wait management strategy is reasonable for up to 2.5 years and 4 follow-up scans at an interval of 6-12 months should be implemented. A Thy2 result on a U3 nodule should not be taken as completely reassuring, a high index of suspicion of malignancy must be maintained.
