Understanding how and why users might use NHS repositories: A mixed methods studyBackground There is little evidence on the use or potential use of NHS repositories within the UK. Methods A mixed methods (quantitative/qualitative) study of two repositories: amber - the home of ambulance service research, and EMER (East Midlands Evidence Repository). A structured online questionnaire was distributed via the repository home page, promoted via social media, email networks, and lists. Next, three research leaders were interviewed in-person online (see Appendix 1). Transcripts of the recorded interviews were summarised using ChatGPT 3.5. Results From the 148 questionnaire responses, 38% of respondents had used an NHS repository. Librarian activities were key to encouraging repository use (that is, searching and depositing materials). ResearchGate was the most widely used alternative. Perceived benefits of using repositories included open access to materials, and knowledge sharing with colleagues. Users generally did not know the deposit process, and over 50% of respondents were unaware of Green Open Access. Discussion Building greater awareness, and institutional support is key to increasing repository usage. Marketing activities and educating researchers about the benefits of engaging with the repository are fundamental. Conclusion NHS librarians need to market NHS repositories using principles of knowledge management and ensure that the grey literature of research and evaluation reports in repositories is better used.

A deep learning approach to case prioritisation of colorectal biopsies.AIMS: To create and validate a weakly supervised artificial intelligence (AI) model for detection of abnormal colorectal histology, including dysplasia and cancer, and prioritise biopsies according to clinical significance (severity of diagnosis). MATERIALS AND METHODS: Triagnexia Colorectal, a weakly supervised deep learning model, was developed for the classification of colorectal samples from haematoxylin and eosin (H&E)-stained whole slide images. The model was trained on 24 983 digitised images and assessed by multiple pathologists in a simulated digital pathology environment. The AI application was implemented as part of a point and click graphical user interface to streamline decision-making. Pathologists assessed the accuracy of the AI tool, its value, ease of use and integration into the digital pathology workflow. RESULTS: Validation of the model was conducted on two cohorts: the first, on 100 single-slide cases, achieved micro-average model specificity of 0.984, micro-average model sensitivity of 0.949 and micro-average model F1 score of 0.949 across all classes. A secondary multi-institutional validation cohort, of 101 single-slide cases, achieved micro-average model specificity of 0.978, micro-average model sensitivity of 0.931 and micro-average model F1 score of 0.931 across all classes. Pathologists reflected their positive impressions on the overall accuracy of the AI in detecting colorectal pathology abnormalities. CONCLUSIONS: We have developed a high-performing colorectal biopsy AI triage model that can be integrated into a routine digital pathology workflow to assist pathologists in prioritising cases and identifying cases with dysplasia/cancer versus non-neoplastic biopsies.

Presenting Symptoms Define Time to Diagnosis in Degenerative Cervical Myelopathy: Process Mapping From a Musculoskeletal Triage Unit in the UK.STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Tackling delayed diagnosis in degenerative cervical myelopathy (DCM) is a global research priority. On average, it takes 2-5 years, leading to worse outcomes from surgery and greater disability. Many countries in the UK use interface triage units run by specialist physiotherapists that sit between primary and secondary care termed musculoskeletal services. Their role in the efficient diagnosis of DCM is unknown. The aim of this study was to map the journey of the patient in the musculoskeletal service and to establish the presenting signs and symptoms. METHODS: A retrospective review of 2.5 years of clinical notes was performed in a musculoskeletal service. Process mapping was utilised to visualise the patient's journey and identify delays to diagnosis and presenting signs and symptoms. RESULTS: Twenty-seven cases were reviewed. Patients spent an average of three months in the service. There was a wide variety of presenting symptoms. DCM was more often suspected if patients had both upper limb symptoms and gait disturbance or pathological reflexes. Delays occurred when patients had no gait disturbance or a normal or incomplete neurological assessment. Longest delays occurred when patients received electrophysiology tests for differential diagnosis of peripheral neuropathies. Delays were also seen with incorrect triaging of MRI results. CONCLUSIONS: Where DCM is the principal differential diagnosis, diagnosis was faster. Incomplete examination, misinterpretation of MRI findings or delays in other investigations contributed to delays. Improved awareness and protocols of care within musculoskeletal services represent an opportunity to accelerate diagnosis in DCM.

An exploration of the utilisation and impact of restraint practices in acute paediatric settings: A narrative review of global literaturePurpose: The purpose of this paper will be to ascertain the underpinning reason for restraint use in the acute paediatric setting. In the UK, presentations for mental health-related needs within paediatric settings have increased. These admissions can be associated with patients with significant mental health and trauma histories who present with behaviours that challenge, risking exposure to higher levels of restrictive practice. Design/methodology/approach: A literature review was conducted across five databases, PsychINFO, EMCARE, EMBASE, MEDLINE and CINAHL. Search terms related to “paediatrics” and “restraint” were used. In all, 116 studies were screened with 78 studies being retrieved for analysis. A total of eight studies were included for review. All studies were quality assessed using the appropriate tool that adhered to each respective design. Findings: Five themes were extracted from the analysis and presented. These themes were identified as “restraint as part of the role of paediatric nursing”, “culture and attitudes”, “lack of guidance and agreed terminology”, “lack of other alternatives” and “training”. Restraint in paediatrics is unregulated not only in the UK but also globally. Positive behaviour support is highlighted as an approach for restraint reduction in paediatric settings. Originality/value: This literature review identifies a significant lack of research regarding restraint for young people with mental health presentations in the paediatric setting. This paper sets forth the need for future research both in the UK and globally.

Implementing Mental Practice in Postgraduate Surgical Training for Minimally Invasive Surgery: A Systematic Review and Thematic Analysis.BACKGROUND: Unprecedented pressure on the National Health Service (NHS) has meant that there are increasing obstacles to surgical training. Simulation training is an option to improve surgical performance but is limited due to availability, accessibility and financial constraints. Mental practice (MP) has been proposed as a potential solution to supplement the traditional method of apprenticeship-style learning. Despite increasing evidence that MP may be a useful tool to improve surgical performance and reduce surgeon anxiety, it is not widely adopted. This systematic review and thematic analysis aims to identify key themes that would allow for the successful implementation of MP in postgraduate surgical training. METHODS: Medline, Embase and PsycINFO databases were systematically searched to identify articles that investigate the role of MP in improving surgical performance amongst surgical trainees. Retrieved papers were studied to inform thematic analysis of their content and studies were assessed for bias. RESULTS: A total of 321 studies were retrieved, of which 11 met the inclusion criteria. Overall risk of bias was assessed to be between critical and moderate for seven nonrandomized studies and between fair and good for four randomized studies. Key themes were identified and discussed using a thematic analysis approach. CONCLUSION: This study has identified that attaining high quality mental imagery is fundamental to success in mental practice and this can be augmented by the use of relaxation therapy and/or motivational imagery. Future research should focus on the application of MP in real-world surgical practice and breaking down complex procedures into fewer operative steps.

Development and validation of a gonadotropin dose selection model for optimized ovarian stimulation in IVF/ICSI: an individual participant data meta-analysis.BACKGROUND: The ovarian response to gonadotropin stimulation varies widely among women, and could impact the probability of live birth as well as treatment risks. Many studies have evaluated the impact of different gonadotropin starting doses, mainly based on predictive variables like ovarian reserve tests (ORT) including anti-Müllerian hormone (AMH), antral follicle count (AFC), and basal follicle-stimulating hormone (bFSH). A Cochrane systematic review revealed that individualizing the gonadotropin starting dose does not affect efficacy in terms of ongoing pregnancy/live birth rates, but may reduce treatment risks such as the development of ovarian hyperstimulation syndrome (OHSS). An individual patient data meta-analysis (IPD-MA) offers a unique opportunity to develop and validate a universal prediction model to help choose the optimal gonadotropin starting dose to minimize treatment risks without affecting efficacy. OBJECTIVE AND RATIONALE: The objective of this IPD-MA is to develop and validate a gonadotropin dose-selection model to guide the choice of a gonadotropin starting dose in IVF/ICSI, with the purpose of minimizing treatment risks without compromising live birth rates. SEARCH METHODS: Electronic databases including MEDLINE, EMBASE, and CRSO were searched to identify eligible studies. The last search was performed on 13 July 2022. Randomized controlled trials (RCTs) were included if they compared different doses of gonadotropins in women undergoing IVF/ICSI, presented at least one type of ORT, and reported on live birth or ongoing pregnancy. Authors of eligible studies were contacted to share their individual participant data (IPD). IPD and information within publications were used to determine the risk of bias. Generalized linear mixed multilevel models were applied for predictor selection and model development. OUTCOMES: A total of 14 RCTs with data of 3455 participants were included. After extensive modeling, women aged 39 years and over were excluded, which resulted in the definitive inclusion of 2907 women. The optimal prediction model for live birth included six predictors: age, gonadotropin starting dose, body mass index, AFC, IVF/ICSI, and AMH. This model had an area under the curve (AUC) of 0.557 (95% confidence interval (CI) from 0.536 to 0.577). The clinically feasible live birth model included age, starting dose, and AMH and had an AUC of 0.554 (95% CI from 0.530 to 0.578). Two models were selected as the optimal model for combined treatment risk, as their performance was equal. One included age, starting dose, AMH, and bFSH; the other also included gonadotropin-releasing hormone (GnRH) analog. The AUCs for both models were 0.769 (95% CI from 0.729 to 0.809). The clinically feasible model for combined treatment risk included age, starting dose, AMH, and GnRH analog, and had an AUC of 0.748 (95% CI from 0.709 to 0.787). WIDER IMPLICATIONS: The aim of this study was to create a model including patient characteristics whereby gonadotropin starting dose was predictive of both live birth and treatment risks. The model performed poorly on predicting live birth by modifying the FSH starting dose. On the contrary, predicting treatment risks in terms of OHSS occurrence and management by modifying the gonadotropin starting dose was adequate. This dose-selection model, consisting of easily obtainable patient characteristics, aids in the choice of the optimal gonadotropin starting dose for each individual patient to lower treatment risks and potentially reduce treatment costs.

TOURISM study (Treatment Outcomes in UteRIne SarcoMa): a 10-year retrospective evaluation of practice in the UK.BACKGROUND: Although rare, uterine sarcomas account for a high proportion of uterine cancer mortality. Treatment options and robust trial data are limited. OBJECTIVES: The TOURISM study (Treatment Outcomes in UteRIne SarcoMa) is a UK-wide study by the National Oncology Trainees Collaborative for Healthcare Research which aimed to characterise this patient cohort. DESIGN: A retrospective descriptive cohort study. Patients with carcinosarcomas/mixed Mullerian tumours, non-uterine gynaecological sarcomas and uterine metastases were excluded. Routine clinical data, including general patient demographics, diagnosis, treatment and outcomes, were collated and pseudonymised. SETTING: Patients diagnosed with uterine sarcoma in the UK National Health Service between 1 January 2008 and 31 December 2017 were identified from electronic records. PARTICIPANTS: A total of 406 patients from eight centres were eligible for inclusion. RESULTS: The median age at diagnosis was 56 years, with leiomyosarcoma the most common diagnosis (54.4%). The majority (57.9%) were diagnosed at the International Federation of Gynecology and Obstetrics stage I, with 19.7% diagnosed at stage IV. Nearly half (45.2%) of the patients received at least one line of chemotherapy, of which most (81.0%) received doxorubicin first-line. In the stage I group 7.4% received adjuvant chemotherapy and 15.0% received adjuvant radiotherapy. Median overall survival was 37 months; however, survival varied significantly by stage at diagnosis (stage I: 105 months; stage II: 33 months; stage III: 19 months; stage IV: 14 months). CONCLUSIONS: Our data highlight the diversity in patient management in uterine sarcoma and a marked survival advantage for patients diagnosed with stage I disease. These data highlight the importance of a multidisciplinary approach and describe real-world trends in systemic therapies, radiotherapy and surgical treatment in this rare cancer type.

Frequency and Reporting of Complications after Dupuytren Contracture Interventions: A Systematic Review and Meta-Analysis.BACKGROUND: Numerous complications are reported following interventions for Dupuytren contracture; however, their incidence, management, and outcomes remain poorly reported. The aims of this review were to report the proportions of complications, compare likelihood of complications between interventions, and evaluate reporting. METHODS: Patient demographics, interventions, complications, their management, and outcomes were extracted. Analysis of descriptive data enabled review of reporting. Meta-analysis (MA) of noncomparative data sets enabled estimation of proportions of patients experiencing complications. Network meta-analysis (NMA) of comparative studies estimated the relative occurrence of complications between interventions. RESULTS: Twenty-six studies, comprising 10,831 patients, were included. Interventions included collagenase injection, percutaneous needle fasciotomy (PNF), limited fasciectomy (LF), open fasciotomy (OF), and dermofasciectomy (DF). Overall quality and consistency of outcomes reporting was poor. MA enabled estimates of probabilities for 3 common complications across all interventions; the reported rates for LF were 4.5% for infection, 3% for nerve injury, and 3.3% for CRPS. LF, the most common intervention, was used as the reference intervention for comparison of the most common complications via NMA, including hematoma (OF odds ratio, 0.450 [95% CI, 0.277 to 0.695]; PNF odds ratio, 0.245 [95% CI, 0.114 to 0.457]), infection (PNF odds ratio, 0.2 [95% CI, 0.0287 to 0.690]; DF odds ratio, 2.02 [95% CI, 1.02 to 3.74]), and neurapraxia [PNF odds ratio, 0.0926 [95% CI, 0.00553 to 0.737]). CONCLUSIONS: There was limited reporting of complication occurrence, management, and outcomes, contributing to a gap in information for informed patient consent. MA was possible for reporting of proportions for infection, nerve injury, and CRPS. NMA enabled direct comparison of the 6 most common complications between interventions. Improving consistency and quality in complications reporting aids counseling of patients regarding the true rates and consequences of the risks of interventions, which can guide selection.

Patient-reported outcomes in studies of diabetes technology: What matters.In recent years, diabetes technologies have revolutionized the care of people with type 1 diabetes (T1D). Emerging evidence suggests that people with type 2 diabetes (T2D) can experience similar benefits from these advances in technology. While glycaemic outcomes are often a primary focus, the lived experience of the person with diabetes is equally important. In this review, we describe the impact of diabetes technologies on patient-reported outcome measures (PROMs). We highlight that most of the published studies investigated PROMs as secondary outcomes. Continuous glucose monitoring systems may have an important role in improving PROMs in individuals with T1D, which may be driven by the prevention or proactive management of hypoglycaemia. In people with T2D, continuous glucose monitoring may also have an important role in improving PROMs, particularly in those treated with insulin therapy. The impact of insulin pumps on PROMs seems positive in T1D, while there is limited evidence in T2D. Studies of hybrid closed-loop therapies suggest increased treatment satisfaction, improved quality of life and decreased diabetes-related distress in T1D, but it is unclear whether these benefits are because of a 'class-effect' or individual systems. We conclude that PROMs deserve a more central role in trials and clinical practice, and we discuss directions for future research.

Improving Patient Care and Streamlining Follow-Up: Compliance With National Institute for Health and Care Excellence (NICE) Guidelines for Pediatric Distal Radius Buckle Fractures.INTRODUCTION: Torus fractures, also known as buckle fractures, are among the most common types of fractures seen in children who present to the emergency department (ED). These injuries usually occur when a child falls onto an outstretched hand, resulting in the compression and buckling of the dorsal cortex of the radius while the volar cortex remains intact. These fractures generally have a good prognosis and heal well with simple immobilization with a low risk of complications. However, current treatment practices often involve using a rigid cast and scheduling multiple follow-up clinic visits, which increases the hospital's financial strain. MATERIALS AND METHODS: We conducted an initial audit that reviewed the practice in our unit between August and October 2017 at Queen's Hospital, Burton Upon Trent, United Kingdom. It included all children below the age of 16 who had radiograph images confirming distal radius buckle fractures and have been referred to the fracture clinic. Patient demographics, clinic visits, treating doctor grade/specialty, radiographs, initial and final treatment outcomes, and cast application were collected. After the initial audit, compliance with National Institute for Health and Care Excellence (NICE) guidelines was promoted through the education of healthcare providers. A second audit was performed within 12 months to reassess the compliance. RESULTS: This study looked at the management of pediatric distal radius buckle fractures in a cohort of 152 patients, of which 65 and 87 children were included in audit cycles I and II, respectively. In the ED, splint usage increased from 0% in the first cycle (all children initially treated in a back slab) to 20% following new recommendations. In the fracture clinic, there was a notable improvement in the use of splints over full plaster casts between the first and second cycles. Initially, in the first cycle, only 5% of patients were treated in a splint, with 95% receiving full plaster casts. Following recommendations, splint use increased significantly in the second cycle, rising to 53%, while cast use decreased to 47%. In the first audit, only 7.7% (five patients) were discharged at the first visit, compared to 44.8% (39 patients) in the second audit. In the first audit, 86.2% (56 patients) required a second visit, whereas in the second audit, this decreased to 55.2% (48 patients). Four individuals received a cast owing to splint size difficulties or patient preferences. CONCLUSION: Despite the improvement seen regarding compliance with NICE guidelines, work is still needed to further enhance compliance. Staff education and optimizing splint availability will be a priority to reduce the burden on fracture clinic resources by unnecessary follow-up appointments.

Prevalence of Emotional and Binge Eating Among Patients With Obesity Attending a Specialist Weight Management Service for Bariatric Surgery in the United Kingdom.BACKGROUND: Emotional eating (EE) is a tendency to consume food in response to positive or negative emotions, leading to obesity and an increased Body Mass Index (BMI). Evidence supports the positive association between EE and binge eating disorder (BED), but little is known about its prevalence among patients referred for bariatric surgery and the psychological characteristics of this patient population. We aim to examine (i) the prevalence of binge eating and EE, (ii) its association with the prevalence of anxiety, depression, diabetes and hypertension and (iii) the correlation between anxiety and depression with emotional and binge eating behaviours among patients attending a regional bariatric service in the UK. METHOD: A cross-sectional case file design involving 285 participants (mean age = 43.88 ± 11.5, female (80.7%) and male (19.3%)) was used. Outcome measures included body weight, BMI, the Weight Loss Readiness (WLR) Questionnaire, Generalised Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9) and Alcohol Use Disorders Identification Test- Consumption (AUDIT-C). RESULTS: Within this patient group, the prevalence of binge eating and EE were 28.8% and 22.1% respectively. Among these, 19.3% had diabetes mellitus, 24.8% hypertension, 21% harmful alcohol use, 65% had high anxiety score and 77% high depression scores. Most correlations between body weight and variables like AUDIT-C, GAD-7, PHQ-9 scores and WLR scores for hunger, binge eating and EE were not significant. A positive association was observed between depression and anxiety with binge eating, and EE behaviours. CONCLUSION: Patients awaiting bariatric surgery have a wide range of mental and physical health comorbidities, with evidence of positive associations between higher depression and anxiety levels with abnormal eating behaviours. These findings highlight the need for screening for comorbidities in this patient population to optimise patient outcomes postbariatric surgery.

Exploring the utility of ultrasound to assess disuse atrophy in different muscles of the lower leg.BACKGROUND: Skeletal muscle is a highly plastic tissue crucial for many functions associated with whole-body health across the life course. Magnetic resonance imaging (MRI) is the current gold standard for measuring skeletal muscle size. However, MRI is expensive, and access to facilities is often limited. B-mode ultrasonography (U/S) has been proposed as a potential alternative to MRI for the assessment of muscle size. However, to date, no work has explored the utility of U/S to assess disuse muscle atrophy (DMA) across muscles with different atrophy susceptibility profiles, an omission which may limit the clinical application of previous work. METHODS: To address this significant knowledge gap, 10 young men (22 ± years, 24.1 ± 2.3 kg/m2) underwent 15-day unilateral leg immobilization using a knee-brace and air boot. Cross-sectional area (CSA) and muscle thickness (MT) of the tibialis anterior (TA) and medial gastrocnemius (MG) were assessed via U/S before and after immobilization, with CSA and muscle volume assessed via MRI. RESULTS: With both muscles combined, there were good correlations between each U/S and MRI measure, both before (e.g., CSAMRI vs. MTU/S and CSAU/S: r = 0.88 and 0.94, respectively, both P < 0.0001) and after (e.g., VOLMRI vs. MTU/S and CSAU/S: r = 0.90 and 0.96, respectively, both P < 0.0001) immobilization. The relationship between the methods was notably stronger for MG than TA at each time-point (e.g., CSAMRI vs. MTU/S: MG, r = 0.70, P = 0.0006; TA, r = 0.37, P = 0.10). There was no relationship between the degree of DMA determined by the two methods in either muscle (e.g., TA pre- vs. post-immobilization, VOLMRI: 136 ± 6 vs. 133 ± 5, P = 0.08; CSAU/S: 6.05 ± 0.3 vs. 5.92 ± 0.4, P = 0.70; relationship between methods: r = 0.12, P = 0.75). CONCLUSIONS: Both MTU/S and CSAU/S provide comparable static measures of lower leg muscle size compared with MRI, albeit with weaker agreement in TA compared to MG. Although both MTU/S and CSAU/S can discern differences in DMA susceptibility between muscles, neither can reliably assess degree of DMA. Based on the growing recognition of heterogeneous atrophy profiles between muscles, and the topical importance of less commonly studied muscles (i.e., TA for falls prevention in older adults), future research should aim to optimize accessible methods to determine muscle losses across the body.

Does long-term surveillance of primary linked total elbow arthroplasty identify failing implants requiring revision?BACKGROUND: Scoping review has identified a lack of evidence guiding long-term follow-up of elbow arthroplasty. We report the effectiveness of primary linked total elbow arthroplasty surveillance in identifying failing implants requiring revision. METHODS: A prospective database recording consecutive primary linked total elbow arthroplasty and subsequent surveillance in an elbow unit was analysed. Arthroplasties performed between 01.10.2013 and 31.07.2022 were included, with a minimum 1-year follow-up. Surveillance involves specialist physiotherapist review 1, 2, 3, 5, 8 and 10 years postoperatively. Patient-initiated review could occur between time points. Outcome measures include a number of surveillance reviews offered and attended; and the proportion that identified a failing implant requiring revision. RESULTS: Ninety-seven primary linked total elbow arthroplasties with minimum 1-year follow-up were performed (76 Discovery, 14 Nexel, 7 Coonrad/Morrey). Sixteen patients died prior to 31.07.2023, and three implants required revision <1 year postoperatively. 290 of 328 offered surveillance appointments were attended (88.4%). Five implants required revision ≥1 year post-operatively, with revision requirements identified by surveillance in all cases. Three failures occurred at 5 years postoperatively, and two failures occurred at 8 years postoperatively. Overall, 1.7% attended surveillance appointments identified a failing implant requiring revision. DISCUSSION: This is the first series reporting the effectiveness of primary linked total elbow arthroplasty surveillance in identifying implants requiring revision.

Feasibility of embedding orthopaedic clinical trials into national registries: a pilot quality improvement study for the UK Non-Arthroplasty Hip Registry (UK-NAHR).The integration of 'Registry-based Randomised Control Trials' (RRCT) into national registries has the potential to catalyse prospective research, enhancing the evidence base for practice. The aim of this study was to assess the feasibility of embedding a trial within the UK Non-Arthroplasty Hip Registry. This was a national observational, multi-centre study. Six pilot sites within the UK were provided with additional support for data collection. We compared the ability of these pilot sites to collect data with the ability of centres where no additional support was provided. We collected information on patient compliance, efficacy and adverse events of drugs routinely used after hip preserving surgery. The primary outcome measure was compliance with data collection in these centres at 30 and 90 days after surgery. Our intention was to assess the feasibility of, and factors influencing, the capturing data for interventional registry trials in the future. Two hundred and twenty-eight patients were enrolled in the Non-Arthroplasty Hip Registry during the study period (114 within pilot centres and 114 in non-pilot centres). Pilot centres had a mean follow-up compliance of 79% (30 days) and 69.4% (90 days) in contrast to 55% (30 days) and 47% (90 days) in the non-pilot centres (P = 0.009/P = 0.0058). The study revealed that supplementary administrative support resulted in improved compliance. However, deficient administration systems negatively impacted follow-up, and surgeon motivation emerged as a crucial determinant in ensuring robust follow-up. The lessons learned from this feasibility trial could be useful for any national registry embedding prospective, registry-based trials.

The effect of pre-operative exercise training on post-operative cognitive function: a systematic review.BACKGROUND: With population aging and advances in surgical and anesthetic procedures, the incidence of surgery in patients over the age of 65 years is increasing. One post-operative complication often encountered by older surgical patients is post-operative cognitive dysfunction (POCD). Preoperative exercise training can improve the overall physiological resilience of older surgical patients, yet its impact on post-operative cognition is less well-established. METHODS: Six databases (Medline (OVID); EMBASE (OVID); EMCARE (OVID); CINAHL (EBSCOHost), the Cochrane Library, and PubMed) were searched for studies reporting the effect of pre-operative physical training on post-operative cognition. The quality of evidence was assessed using the Mixed Methods Assessment Tool. RESULTS: A total of 3983 studies were initially identified, three of which met the inclusion criteria for this review. Two studies were pilot randomized trials, and one was a prospective randomized trial. Two of the studies were high-quality. Each study used a different type of physical exercise and cognition assessment tool. Across the studies, post-operative cognition (p = 0.005) and attention (p = 0.04) were found to be better in the intervention groups compared to control, with one study reporting no difference between the groups. CONCLUSION: Preoperative physical training may improve post-operative cognitive function, although more research with a consistent endpoint is required. Future studies should focus on patients at high risk of POCD, such as older adults, and explore the impact of different exercise regimes, including frequency, intensity, time, and type.

Structured training pathway for robotic colorectal surgery: Short-term outcomes from five UK centresAIM: The aim of this study was to assess the short-term outcomes of robotic colorectal surgery implemented through a structured, standardized training pathway in five colorectal centres in the United Kingdom. METHOD: A multicentre retrospective observational study was conducted, involving 523 consecutive patients who underwent robotic colorectal resection between 2015 and 2019. All participating centres followed the European Academy of Robotic Colorectal Surgery training pathway. Patient data, including demographics, operative details, postoperative outcomes and pathology results, were collected and analysed. RESULTS: The study included 447 rectal resections and 76 colonic operations. The median age of the patients was 64.7 years, with the majority of patients (70%) being men. The mean body mass index was 27.4 kg/m2, and 89.7% of the patients underwent surgery for malignancy. The overall conversion rate to open surgery was 4.2%. The median length of stay was 6 days and there was no 30-day mortality. The readmission and reoperation rates were 8.8% and 7.3%, respectively. The anastomotic leak rate was 4.1% for rectal resections and 3.9% for colonic resections. Pathological examination showed a positive circumferential resection margin rate of 2.6%. CONCLUSION: Through the implementation of a structured, standardized training pathway, the participating colorectal centres in the UK achieved safe and effective robotic colorectal surgery pathways with favourable short-term oncological and clinical outcomes. Further studies examining long-term and functional outcomes are needed to assess the broader impact of robotic surgery in colorectal procedures.

Association Between Neutrophil-to-Lymphocyte Ratio and Sepsis Severity in ICU Patients.Background Sepsis is a potentially fatal condition that necessitates prompt identification and assessment of its severity for effective management. However, evaluating sepsis severity using the Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE II) scores can be complex and costly. This study aimed to assess the association between neutrophil-to-lymphocyte ratio (NLR) and sepsis severity, as well as the role of NLR as a predictive indicator of sepsis severity in ICU patients. Methods This cross-sectional study was conducted among 180 ICU-admitted patients at Benazir Bhutto Hospital (BBH) in Rawalpindi, Pakistan, from January 2022 to January 2023. Participants were enrolled using defined inclusion and exclusion criteria along with consecutive sampling. Following ethical approval and informed consent, data were collected using a self-structured form. The study population was divided into three groups based on sepsis severity, which was assessed via the SOFA score. Data analysis was performed using IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, NY, USA) through chi-squared tests, one-way ANOVA, Pearson's correlation, and a simple linear regression model, with a significance threshold set at p < 0.05. Results In the study population of 180 patients, the frequencies of sepsis, severe sepsis, and septic shock were 69 (38.34%), 86 (47.78%), and 25 (13.88%), respectively. Significant variations were observed among the three study groups in the means of the PaO2/FiO2 ratio, mean arterial pressure, Glasgow Coma Scale score, total bilirubin level, serum creatinine level, platelet count, SOFA score, neutrophil count, lymphocyte count, and NLR (p < 0.05). Pearson's correlation analysis indicated a strong positive correlation between the NLR and SOFA score, with a correlation coefficient (r) of 0.80 and significance at p < 0.001. Furthermore, linear regression analysis identified NLR as a significant predictor of sepsis severity, with a beta coefficient (β) of 3.55 and a 95% CI of 1.92-5.60 (p < 0.001). Conclusions In the current study, a positive and significant correlation was found between the NLR and the severity of sepsis. Higher NLR values were associated with increased SOFA scores, indicating a greater severity of sepsis. This study supports the use of NLR as a complementary and cost-effective tool for the early detection of high-risk patients with sepsis, facilitating timely interventions and improving outcomes, particularly in under-resourced healthcare settings.

Ambulatory management of acute uncomplicated diverticulitis (AmbUDiv study): a multicentre, propensity score matching study.INTRODUCTION: Recent studies have suggested that ambulatory management is feasible for acute uncomplicated diverticulitis (AUD); however, there is still no consensus regarding the most appropriate management settings. This study presents a multi-centre experience of managing patients presenting with AUD, specifically focusing on clinical outcomes and comparing ambulatory treatment with in-patient management. METHODS: A retrospective multi-centre study was conducted across four hospitals in the UK and included all adult patients with computed tomography (CT) confirmed (Hinchey grade 1a) acute diverticulitis over a 12-month period (January - December 2022). Patient medical records were followed up for 1-year post-index episode, and outcomes were compared between those treated through the ambulatory pathway versus inpatient treatment using 1:1 propensity score matching (PSM). All statistical analysis was performed using the R Foundation for Statistical Computing, version 4.4. RESULTS: A total of 348 patients with Hinchey 1a acute diverticulitis were included (260 in-patients; 88 ambulatory pathway), of which nearly a third (31.3%) had a recurrent disease. Inpatient management was dominant (74.7%), with a median of 3 days of hospital stay. PSM resulted in 172 patients equally divided between the two care settings. Ambulatory management was associated with a lower readmission rate (P = 0.02 before PSM, P = 0.08 after PSM), comparable surgical (P = 0.57 before PSM, 0% in both groups after PSM) and radiological interventions (P = 0.99 before and after PSM) within one year. In both matched and non-matched groups, a strong association between readmissions and inpatient management was noted in univariate analysis (P = 0.03 before PSM, P = 0.04 after PSM) and multivariate analysis (P = 0.02 before PSM, P = 0.03 after PSM). CONCLUSION: Our study supports the safety and efficacy of managing patients with AUD through a well-designed ambulatory care pathway. In particular, hospital re-admission rates are lower and other outcomes are non-inferior to in-patient treatment. This has implications for substantial cost-savings and better utilisation of limited healthcare resources.

What Are the Most Clinically Effective Nonoperative Interventions for Thumb Carpometacarpal Osteoarthritis? An Up-to-date Systematic Review and Network Meta-analysis.BACKGROUND: Thumb carpometacarpal osteoarthritis (CMC-1 OA) is a common and debilitating condition, particularly among older adults and women. With the aging population, the prevalence of CMC-1 OA is expected to rise, emphasizing the need to find effective nonoperative strategies. So far, for determining the most effective nonoperative interventions in CMC-1 OA, two network meta-analyses (NMAs) have been published. However, these NMAs were limited to specific intervention types: one comparing multiple splints and the other comparing different intraarticular injections. Therefore, an NMA that compared all nonoperative intervention types is urgently needed. QUESTIONS/PURPOSES: This study aimed to assess and compare the effectiveness of available nonoperative interventions (both nonpharmacologic and pharmacologic) for CMC-1 OA to establish which nonoperative options are more effective than control in terms of (1) pain, (2) function, and (3) grip strength. METHODS: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) NMA guidelines (PROSPERO: CRD2021272247) and conducted a comprehensive search across Medline, Embase, CENTRAL, and CINAHL up to March 2023. We included randomized controlled trials (RCTs) and quasi-RCTs evaluating nonoperative interventions for symptomatic CMC-1 OA, excluding inflammatory or posttraumatic arthritis. Studies comparing ≥ 2 interventions or against a control, focusing on pain reduction, functional improvement, and grip strength, were selected. We assessed methodologic quality using the modified Coleman Methodology Score, including only studies scoring > 70. Risk of bias was evaluated with the Risk of Bias 2.0 tool, and evidence quality with Confidence in Network Meta-Analysis (CINeMA). Of 29 screened studies, 22 (21 RCTs and one quasi-RCT) were included, involving 1631 women and 331 men. We analyzed eight different nonoperative interventions, including splints, hand exercises, injections, and multimodal treatment (≥ 2 nonpharmacologic interventions or nonpharmacologic with a pharmacologic intervention). Six studies had a low risk of bias, eight had a high risk, and the remainder were moderate. We extracted mean and SD scores, and NMA and pairwise analyses were performed at short- (≤ 3 months) and medium-term (> 3 to ≤ 12 months) time points. Standardized mean differences were re-expressed into common units for interpretation, which were the VAS (range 0 to 10) for pain, the DASH test (range to 100) for function, and pounds for grip strength. Clinical recommendations were considered strong if the mean differences exceeded the minimum clinically important difference-1.4 points for VAS, 10 points for DASH, and 14 pounds for grip strength-and were supported by moderate or high confidence in the evidence, as assessed using CINeMA methodology. RESULTS: Our NMA (based on moderate or high confidence) showed a clinically important reduction in pain at the short-term time point for multimodal treatment and hand exercises versus control (mean difference VAS score -5.3 [95% confidence interval (CI) -7.6 to -3.0] and -5.0 [95% CI -8.5 to -1.5]). At the medium-term time point, only the rigid carpometacarpal-metacarpophalangeal (CMC-MCP) splint was superior to control (mean difference VAS score -1.9 [95% CI -3.1 to -0.6]) and demonstrated clinical importance. For function, only the rigid CMC-MCP splint demonstrated a clinically important improvement at the medium-term time point versus control (mean difference DASH score -11 [95% CI -21 to -1]). Hand exercises resulted in a clinically important improvement in short-term grip strength versus control (mean difference 21 pounds [95% CI 11 to 31]). CONCLUSION: This systematic review and NMA show that multimodal treatment and hand exercises reduce short-term pain and improve grip strength, while a rigid CMC-MCP splint enhances medium-term function. Future research should evaluate long-term efficacy. LEVEL OF EVIDENCE: Level I, therapeutic study.
