BackgroundThe National Early Warning Score + Lactate (NEWS+L) Score has been previously shown to outperform NEWS alone in prediction of mortality and need for critical care in a small adult ED study. We validated the score in a large patient data set and constructed a model that allows early prediction of the probability of clinical outcomes based on the individual’s NEWS+L Score.MethodsIn this retrospective study, we included all adult patients who visited the ED of a single urban academic tertiary-care university hospital in South Korea for five consecutive years (1 January 2015 to 31 December 2019). The initial (ResultsAfter excluding 808 patients (0.5%) from 149 007 patients in total, the study cohort consisted of 148 199 patients. The mean NEWS+L Score was 3.3±3.8. The AUROC value was 0.789~0.813 for the NEWS+L Score with good calibration (calibration-in-the-large=−0.082~0.001, slope=0.964~0.987, Brier Score=0.011~0.065). The AUPRC values of the NEWS+L Score for outcomes were 0.331~0.415. The AUROC and AUPRC values of the NEWS+L Score were greater than those of NEWS alone (AUROC 0.744~0.806 and AUPRC 0.316~0.380 for NEWS). Using the equation, 48 hours hospital mortality rates for NEWS+L Score of 5, 10 and 15 were found to be 1.1%, 3.1% and 8.8%, and for the composite outcome 9.2%, 27.5% and 58.5%, respectively.ConclusionThe NEWS+L Score has acceptable to excellent performance for risk estimation among undifferentiated adult ED patients, and outperforms NEWS alone.

Pharmacology (medical) ,General Medicine - Abstract
Living with multiple long-term health conditions (multimorbidity) is increasingly common in older age. The more long-term conditions that an individual has, the more medicines they are likely to take. Hospitalisation as a consequence of medication-related harm is increasing and a concerted effort is needed to reduce the burden of harm caused by medication. However, making decisions about the balance between benefit and harm for an older person with multimorbidity and polypharmacy is very complex. There are various clinical tools that can help to identify patients at higher risk of harm and numerous strategies, including medicines optimisation reviews that incorporate personalised health information, to try to reduce risk. Further education and training of the healthcare professionals is needed to equip the multidisciplinary workforce with the skills and knowledge to address these challenges. This article discusses some of the changes that can be implemented now and highlights areas that will require more research before they can be introduced, in order to help patients to get the best out of their medicines.

BackgroundUpper gastrointestinal bleeding (UGIB) is a medical emergency with an approximate mortality of 10%, which results in a high hospitalisation rate. The Glasgow-Blatchford score (GBS) is recommended to identify low-risk patients who can be discharged from the emergency department (ED). A modified GBS (mGBS) and CANUKA score have recently been proposed but have not been well studied. The aim of this study was to assess whether the use of GBS, mGBS or CANUKA score could identify patients at low risk of death or need for intervention.MethodsA single-centre retrospective study was performed including patients with suspected UGIB visiting the ED of Saint-Antoine hospital (Paris, France) from January 2016 to December 2018. Demographic and medical data needed to calculate GBS and CANUKA were collected, as well as outcomes data. Need for intervention was defined as the need for blood transfusion, endoscopic haemostasis or rebleeding within 7 days. In-hospital mortality was also collected. Sensitivity, specificity and predictive values were measured for the score thresholds of interest.ResultsA total of 386 patients were included. Median age was 60 years (38–78), 65.3% (n=252) were male and 60% (n=233) were hospitalised. A GBS≤1, mGBS=0 and CANUKA≤2 categorised 24.9%, 18.2% and 18.9% of patients as low risk, respectively. There was a need for intervention in 2.2%, 4.6% and 0% of those patients categorised as low risk by GBS, mGBS and CANUKA, respectively. No deaths occurred in the patients identified as low risk, regardless of the score used. All scores had a high sensitivity and negative predictive value.ConclusionsIn patients with UGIB, the use of a GBS≤1 or CANUKA score ≤2 appears to be safe for identifying patients at low risk of death or need for intervention.

Pharmacology (medical) ,General Medicine - Abstract
In early studies in simple organisms and mammalian cell lines, small interfering RNA (siRNA) molecules were found to allow experimental cleavage of intracellular messenger RNA (mRNA; the transcription product of a cell gene), reducing the levels of the proteins that would otherwise be formed by the action of the mRNA, thereby ‘silencing’ a specific gene. Researchers subsequently assessed the effects of this class of molecule in patients with various genetic conditions (eg, hereditary amyloidosis) that could benefit from reductions in the excessive quantities of harmful proteins (eg, amyloid). Due to the hydrophilic (non-fat-soluble) nature of the molecules, they have been formulated as lipid nanoparticles to aid transport into cells or conjugated to molecules with an ability to target certain cells in the body (eg, hepatocytes) to aid specificity of action. Their intracellular effects may last up to several months before they are broken down and inactivated. As they need to be composed of an exact complementary sequence to be able to cleave the target mRNA, they are thought to have few unwanted effects apart from infusion or injection site reactions. Several siRNA medicines have been licensed and many other products are in development for genetic hepatic, cardiovascular and ocular conditions.

Anesthesiology and Pain Medicine ,General Medicine - Abstract
The treatment options for patients with chronic pain conditions are impacted by recent research, patient needs, and insurance coverage. Although various factors affect the cost of healthcare, the economic burden on the patient and the healthcare system must be considered when choosing the appropriate treatments for each patient. This Daring Discourse aims to review and further clarify existing economic evaluations and thus examine cost-effectiveness with regards to neuromodulation for the treatment of persistent spinal pain syndrome and complex regional pain syndrome. Specific consideration is given to spinal cord stimulation, as it is a widely studied and implemented neuromodulation modality for the treatment of these debilitating conditions.

BackgroundSpinal cord stimulation (SCS) has emerged as an important treatment for chronic pain disorders. While there is evidence supporting improvement in pain intensity with SCS therapy, efforts to synthesize the evidence on physical functioning are lacking.ObjectiveThe primary objective of this meta-analysis was to assess long-term physical function following 12 months of SCS for chronic back pain.Evidence reviewPubMed, EMBASE, Scopus, and CENTRAL databases were searched for original peer-reviewed publications investigating physical function following SCS. The primary outcome was physical function at 12 months following SCS therapy for chronic back pain compared with baseline. A random effects model with an inverse variable method was used. The Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) framework was used to determine the certainty of evidence.FindingsA total of 518 studies were screened, of which 36 were included. Twenty-two studies were pooled in the meta-analysis. There was a significant reduction in Oswestry Disability Index (ODI) scores at all time frames up to 24 months following implantation. Pooled results revealed significant improvement in ODI scores at 12 months with a mean difference of −17.00% (95% CI −23.07 to −10.94, pConclusionThis meta-analysis highlights significant improvements in physical function after SCS therapy. However, this finding was limited by a very low GRADE certainty of evidence and high heterogeneity.

Anesthesiology and Pain Medicine ,General Medicine - Abstract
The use of neuromodulation systems is increasing for the treatment of various pathologies ranging from movement disorders to urinary incontinence to chronic pain syndromes. While the type of neuromodulation devices varies, they are largely categorized as intracranial (eg, deep brain stimulation), neuraxial (eg, spinal cord stimulation, dorsal root ganglion stimulation, and intrathecal drug delivery systems), or peripheral (eg, sacral nerve stimulation and peripheral nerve stimulation) systems. Given the increasing prevalence of these systems in the overall population, it is important for anesthesiologists, surgeons, and the perioperative healthcare team to familiarize themselves with these systems and their unique perioperative considerations. In this review, we explore and highlight the various neuromodulation systems, their general perioperative considerations, and notable special circumstances for perioperative management.

Anesthesiology and Pain Medicine ,General Medicine - Abstract
Chronic pain impacts more than 100 million Americans and has a significant impact on the economy and quality of life. Spinal cord stimulation (SCS) has demonstrated efficacy in managing a growing number of chronic pain conditions. This in combination with an increasing number of physicians trained in SCS placement has produced significant changes in utilization, expense and sites of service related to SCS. In particular, there has been a large increase in SCS placement by non-surgeons, use of percutaneous leads and performance in ambulatory surgery centers instead of inpatient settings. There are also notable differences in SCS use related to age, race, insurance coverage and geography. There is a large potential market and use of these therapies is predicted to grow from $2.41 billion in 2020 to $4.12 billion US dollars globally by 2027. At the same time, there is increasing scrutiny around utilization of this therapy related to cost, complications, long-term efficacy and explant rates that has the potential to impact access to this therapy in the future. We must examine our indications, technique and management to optimize outcomes and utilization of SCS going forward.

Anesthesiology and Pain Medicine ,General Medicine - Abstract
Interventional pain management (IPM) options for refractory neuropathic pain (NP) have recently increased with availability of peripheral nerve stimulation (PNS) equipment and expertise. Given a lack of high-quality evidence and guidelines on this topic, we sought to understand the perception of physicians with expertise in treating NP regarding IPM and the role of PNS. We emailed a survey in March 2022 to international NP experts including pain medicine physicians, researchers, and leaders of 11 professional pain societies. No representatives from vendors of PNS systems were included in the design of the survey nor as respondents. Among 24 respondents (67% of those contacted), the distal common peroneal, tibial, and sural nerves were most frequently targeted (60%) with PNS. Persistent postsurgical pain of more than 3 months was the most common indication for PNS (84%). The aggregate NP treatment algorithm in order of median rank was non-opioid medications as first line, IPM including epidural/perineural steroid injections tied with transcutaneous electrical nerve stimulation as second line, pulsed radiofrequency (RF) tied with RF ablation/denervation as third line, temporary then permanent PNS as fourth line, followed by spinal cord stimulation, opioids, cryoablation, botulinum, peripheral nerve field stimulation, intrathecal targeted drug delivery, and others. Before offering PNS, 12 respondents (50%) indicated their preference for trialing non-neuromodulation treatments for 1–3 months. Twenty-two respondents (92%) agreed PNS should be offered early in the treatment of neuropathic pain. The most common barriers to PNS use were cost, lack of high-quality evidence in support of its use, lack of exposure to PNS in training programs, and lack of familiarity with the use of ultrasound guidance. PNS appears to have an increasing role in the treatment of NP but more research is needed on the outcomes of PNS to elucidate its role.

Anesthesiology and Pain Medicine ,General Medicine - Abstract
Peripheral nerve stimulation (PNS), a type of neuromodulatory technique, is increasingly used to treat chronic pain syndromes. PNS has also recently gained popularity as a viable adjunct analgesic modality in acute pain settings, where the practice primarily relies on using boluses or infusion of local anesthetics for nerve blockade, followed by stimulation to extend the analgesia. There is some early promise in PNS for perioperative analgesic control, but considerable obstacles must be addressed before it can be implemented into standard practice. In this daring discourse, we explore the possibilities and constraints of using the PNS paradigm in acute pain.

ObjectivesThe Manchester Acute Coronary Syndromes ECG (MACS-ECG) prediction model calculates a score based on objective ECG measurements to give the probability of a non-ST elevation myocardial infarction (NSTEMI). The model showed good performance in the emergency department (ED), but its accuracy in the pre-hospital setting is unknown. We aimed to externally validate MACS-ECG in the pre-hospital environment.MethodsWe undertook a secondary analysis from the Pre-hospital Evaluation of Sensitive Troponin (PRESTO) study, a multi-centre prospective study to validate decision aids in the pre-hospital setting (26 February 2019 to 23 March 2020). Patients with chest pain where the treating paramedic suspected acute coronary syndrome were included. Paramedics collected demographic and historical data and interpreted ECGs contemporaneously (as ‘normal’ or ‘abnormal’). After completing recruitment, we analysed ECGs to calculate the MACS-ECG score, using both a pre-defined threshold and a novel threshold that optimises sensitivity to differentiate AMI from non-AMI. This was compared with subjective ECG interpretation by paramedics. The diagnosis of AMI was adjudicated by two investigators based on serial troponin testing in hospital.ResultsOf 691 participants, 87 had type 1 AMI and 687 had complete data for paramedic ECG interpretation. The MACS-ECG model had a C-index of 0.68 (95% CI: 0.61 to 0.75). At the pre-determined cut-off, MACS-ECG had 2.3% (95% CI: 0.3% to 8.1%) sensitivity, 99.5% (95% CI: 98.6% to 99.9%) specificity, 40.0% (95% CI: 10.2% to 79.3%) positive predictive value (PPV) and 87.6% (87.3% to 88.0%) negative predictive value (NPV). At the optimal threshold for sensitivity, MACS-ECG had 50.6% sensitivity (39.6% to 61.5%), 83.1% specificity (79.9% to 86.0%), 30.1% PPV (24.7% to 36.2%) and 92.1% NPV (90.4% to 93.5%). In comparison, paramedics had a sensitivity of 71.3% (95% CI: 60.8% to 80.5%) with 53.8% (95% CI: 53.8% to 61.8%) specificity, 19.7% (17.2% to 22.45%) PPV and 93.3% (90.8% to 95.1%) NPV.ConclusionNeither MACS-ECG nor paramedic ECG interpretation had a sufficiently high PPV or NPV to ‘rule in’ or ‘rule out’ NSTEMI alone.

BackgroundThe Internal Medicine Training (IMT) Programme is an evolution of Core Medical Training introduced in 2019. The IMT curriculum places an increased emphasis on palliative care; however, access to palliative care training is variable. Project ECHO (Extension of Community Healthcare Outcomes) develops communities of practice and is a valuable tool for medical education. We report on an evaluation of Project ECHO to deliver palliative medicine training across a geographically large deanery in the North of England.MethodsThe Project ECHO training programme involved multipoint video technology, telementoring, expert talks and case-based discussions over six sessions, and was fully mapped to the palliative care component of the IMT curriculum. We collected data particularly around attendance and self-reported confidence and knowledge.ResultsBy creating a community of practice, we provided virtual placements and over 9 hours of virtual direct contact with palliative medicine consultants; and in total, 921 individual attendances occurred, with 62% attending all six sessions. The course was associated with an increase in self-reported confidence and high satisfaction.DiscussionProject ECHO is an effective method of delivering teaching to trainees across a large geographical area. Course evaluation shows outstanding results in trainee satisfaction, confidence, knowledge, patient care, clinical skills and reduction in fear when managing death and dying.

BackgroundCurrently, there is no consensus on the number of defibrillation attempts that should be made before transfer to a hospital in patients with out-of-hospital cardiac arrest (OHCA). This study aimed to evaluate the association between the number of defibrillations and a sustained prehospital return of spontaneous circulation (ROSC).MethodsA retrospective analysis of a multicentre, prospectively collected, registry-based study in Republic of Korea was conducted for OHCA patients with prehospital defibrillation. The primary outcome was sustained prehospital ROSC, and the secondary outcome was a good neurological outcome at hospital discharge, defined as Cerebral Performance Category score 1 or 2. Cumulative incidence of sustained prehospital ROSC and good neurological outcome according to number of defibrillations were examined. Multivariable logistic regression analysis was used to examine whether the number of defibrillations was independently associated with the outcomes.ResultsExcluding 172 patients with missing data, a total of 1983 OHCA patients who received prehospital defibrillation were included. The median time from arrest to first defibrillation was 10 (IQR 7–15) min. The numbers of patients with sustained prehospital ROSC and good neurological outcome were 738 (37%) and 549 (28%), respectively. Sustained ROSC rates decreased as the number of defibrillation attempts increased from the first to the sixth (16%, 9%, 5%, 3%, 2% and 1%, respectively). The cumulative sustained ROSC rate, and good neurological outcome rate from initial defibrillation to sixth defibrillation were 16%, 25%, 30%, 34%, 36%, 36% and 11%, 18%, 22%, 25%, 26%, 27%, respectively. With adjustment for clinical characteristics and time to defibrillation, a higher number of defibrillations was independently associated with a lower chance of a sustained ROSC (OR 0.81, 95% CI 0.76 to 0.86) and a lower chance of good neurological outcome (OR 0.86, 95% CI 0.80 to 0.92).ConclusionsWe observed no significant increase in ROSC after five defibrillations, and no absolute increase in ROSC after seven defibrillations. These data provide a starting point for determination of the optimal defibrillation strategy prior to consideration for prehospital extracorporeal cardiopulmonary resuscitation (ECPR) or conveyance to a hospital with an ECPR capability.Trial registration numberNCT03222999

BackgroundWhether and how bystander cardiopulmonary resuscitation (CPR) modifies the cardiac rhythm after out-of-hospital cardiac arrest (OHCA) over time remains unclear. We investigated the association between bystander CPR and the likelihood of ventricular fibrillation (VF) or ventricular tachycardia (VT) as the first documented cardiac rhythm.MethodsWe identified individuals with witnessed OHCA of cardiac origin from a nationwide population-based OHCA registry in Japan between 1 January 2005 and 31 December 2019. The first documented cardiac rhythm was compared between patients who received bystander CPR and those who did not, using a 1:2 propensity score-matched analysis.ResultsOf 309 900 patients with witnessed OHCA of cardiac origin, 71 887 (23.2%) received bystander CPR. Propensity score matching paired 71 882 patients who received bystander CPR with 143 764 who did not. The likelihood of detecting a VF/VT rhythm was significantly higher among patients who received bystander CPR than among those who did not (OR 1.66; 95% CI 1.63 to 1.69; pConclusionBystander CPR was associated with a higher VF/VT likelihood and a lower likelihood of pulseless electrical activity at first documented rhythm analysis. Our results support early CPR for OHCA and highlight the need for further research to understand whether and how CPR modifies the cardiac rhythm after arrest.

General Medicine - Abstract
ObjectivesTo assess the benefits and drawbacks of school closures and in-school mitigations during the COVID-19 pandemic.DesignOverview of systematic reviews (SRs).Search methodsWe searched six databases and additional resources on 29 July 2022: MEDLINE, Embase, Google Scholar, Cochrane Library, COVID-END inventory of evidence synthesis, and Epistemonikos.Eligibility criteriaWe selected SRs written in English that answered at least one of four specific questions concerning the efficacy and drawbacks of school closures. Their primary studies were conducted in primary and secondary schools, including pupils aged 5–18. Interventions included school closures or mitigations (such as mask usage) introduced in schools.Data collection and analysisWe used AMSTAR 2 to assess confidence in the included SRs, and GRADE was used to assess certainty of evidence. We performed a narrative synthesis of the results, prioritising higher-quality SRs, those which performed GRADE assessments and those with more unique primary studies. We also assessed the overlap between primary studies included in the SRs.Main outcome measuresOur framework for summarising outcome data was guided by the following questions: (1) What is the impact of school closures on COVID-19 transmission, morbidity or mortality in the community? (2) What is the impact of COVID-19 school closures on mental health (eg, anxiety), physical health (eg, obesity, domestic violence, sleep) and learning/achievement of primary and secondary pupils? (3) What is the impact of mitigations in schools on COVID-19 transmission, morbidity or mortality in the community? and (4) What is the impact of COVID-19 mitigations in schools on mental health, physical health and learning/achievement of primary and secondary pupils?ResultsWe identified 578 reports, 26 of which were included. One SR was of high confidence, 0 moderate, 10 low and 15 critically low confidence. We identified 132 unique primary studies on the effects of school closures on transmission/morbidity/mortality, 123 on learning, 164 on mental health, 22 on physical health, 16 on sleep, 7 on domestic violence and 69 on effects of in-school mitigations on transmission/morbidity/mortality.Both school closures and in-school mitigations were associated with reduced COVID-19 transmission, morbidity and mortality in the community. School closures were also associated with reduced learning, increased anxiety and increased obesity in pupils. We found no SRs that assessed potential drawbacks of in-school mitigations on pupils. The certainty of evidence according to GRADE was mostly very low.ConclusionsSchool closures during COVID-19 had both positive and negative impacts. We found a large number of SRs and primary studies. However, confidence in the SRs was mostly low to very low, and the certainty of evidence was also mostly very low. We found no SRs assessing the potential drawbacks of in-school mitigations on children, which could be addressed moving forward. This overview provides evidence that could inform policy makers on school closures during future potential waves of COVID-19.

Background/importancePatient selection for spinal cord stimulation (SCS) therapy is crucial and is traditionally performed with clinical selection followed by a screening trial. The factors influencing patient selection and the importance of trialing have not been systematically evaluated.ObjectiveWe report a narrative review conducted to synthesize evidence regarding patient selection and the role of SCS trials.Evidence reviewMedline, EMBASE and Cochrane databases were searched for reports (any design) of SCS in adult patients, from their inception until March 30, 2022. Study selection and data extraction were carried out using DistillerSR. Data were organized into tables and narrative summaries, categorized by study design. Importance of patient variables and trialing was considered by looking at their influence on the long-term therapy success.FindingsAmong 7321 citations, 201 reports consisting of 60 systematic reviews, 36 randomized controlled trials (RCTs), 41 observational studies (OSs), 51 registry-based reports, and 13 case reports on complications during trialing were included. Based on RCTs and OSs, the median trial success rate was 72% and 82%, and therapy success was 65% and 61% at 12 months, respectively. Although several psychological and non-psychological determinants have been investigated, studies do not report a consistent approach to patient selection. Among psychological factors, untreated depression was associated with poor long-term outcomes, but the effect of others was inconsistent. Most RCTs except for chronic angina involved trialing and only one RCT compared patient selection with or without trial. The median (range) trial duration was 10 (0–30) and 7 (0–56) days among RCTs and OSs, respectively.ConclusionsDue to lack of a consistent approach to identify responders for SCS therapy, trialing complements patient selection to exclude patients who do not find the therapy helpful and/or intolerant of the SCS system. However, more rigorous and large studies are necessary to better evaluate its role.

Spinal cord stimulation (SCS) has demonstrated effectiveness for neuropathic pain. Unfortunately, some patients report inadequate long-term pain relief. Patient selection is emphasized for this therapy; however, the prognostic capabilities and deployment strategies of existing selection techniques, including an SCS trial, have been questioned. After approval by the Board of Directors of the American Society of Regional Anesthesia and Pain Medicine, a steering committee was formed to develop evidence-based guidelines for patient selection and the role of an SCS trial. Representatives of professional organizations with clinical expertize were invited to participate as committee members. A comprehensive literature review was carried out by the steering committee, and the results organized into narrative reports, which were circulated to all the committee members. Individual statements and recommendations within each of seven sections were formulated by the steering committee and circulated to members for voting. We used a modified Delphi method wherein drafts were circulated to each member in a blinded fashion for voting. Comments were incorporated in the subsequent revisions, which were recirculated for voting to achieve consensus. Seven sections with a total of 39 recommendations were approved with 100% consensus from all the members. Sections included definitions and terminology of SCS trial; benefits of SCS trial; screening for psychosocial characteristics; patient perceptions on SCS therapy and the use of trial; other patient predictors of SCS therapy; conduct of SCS trials; and evaluation of SCS trials including minimum criteria for success. Recommendations included that SCS trial should be performed before a definitive SCS implant except in anginal pain (grade B). All patients must be screened with an objective validated instrument for psychosocial factors, and this must include depression (grade B). Despite some limitations, a trial helps patient selection and provides patients with an opportunity to experience the therapy. These recommendations are expected to guide practicing physicians and other stakeholders and should not be mistaken as practice standards. Physicians should continue to make their best judgment based on individual patient considerations and preferences.

Pharmacology (medical) ,General Medicine - Abstract
Chronic skin disease is common in women of reproductive age. Although skin can improve or remain stable during pregnancy, it is also common for existing conditions to flare and for new conditions to develop. A small number of medications used to control chronic skin disease can potentially have adverse effects on the outcome of the pregnancy. This article forms part of a series on prescribing for pregnancy and highlights the importance of achieving good control of the skin disease prior to conception and during pregnancy. It emphasises the need for patient-centred, open and informed discussions around medication options to achieve good control. During pregnancy and breastfeeding each patient should be treated as an individual in accordance with the medications that are appropriate for them, their preferences, and the severity of their skin disease. This should be done through collaborative working across primary care, dermatology and obstetric services.

ObjectivesTo achieve optimal survival care outcomes, all healthcare services must be tailored to patients’ specific needs, preferences and concerns throughout the survival period. This study aimed to identify supportive care needs from the point of view of breast cancer survivors.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting systematic reviews, a comprehensive search of PubMed, Web of Science and Scopus was performed. The inclusion criteria were studies published from inception to the end of January 2022, covering all stages of breast cancer. The exclusion criteria were mixed-type studies relating to cancer, such as case reports, commentaries, editorials and systematic reviews, as well as studies that assessed patients’ needs during cancer treatment. Two quality assessment tools were used for the qualitative and quantitative studies.ResultsOf the 13 095 records retrieved, 40 studies, including 20 qualitative and 20 quantitative studies, were retained for this review. Survivors’ supportive care needs were classified into 10 dimensions and 40 subdimensions. The most frequently mentioned supportive care needs of survivors were psychological/emotional needs (N=32), health system/informational needs (N=30), physical and daily activities (N=19), and interpersonal/intimacy needs (N=19).ConclusionsThis systematic review highlights several essential needs for breast cancer survivors. Supportive programmes should be designed in order to take into consideration all aspects of these needs, particularly psychological, emotional and informational needs.

BackgroundThis study aimed to estimate the direct healthcare cost burden of acute chest pain attendances presenting to ambulance in Victoria, Australia, and to identify key cost drivers especially among low-risk patients.MethodsState-wide population-based cohort study of consecutive adult patients attended by ambulance for acute chest pain with individual linkage to emergency and hospital admission data in Victoria, Australia (1 January 2015–30 June 2019). Direct healthcare costs, adjusted for inflation to 2020–2021 ($A), were estimated for each component of care using a casemix funding method.ResultsFrom 241 627 ambulance attendances for chest pain during the study period, mean chest pain episode cost was $6284, and total annual costs were estimated at $337.4 million ($68 per capita per annum). Total annual costs increased across the period ($310.5 million in 2015 vs $384.5 million in 2019), while mean episode costs remained stable. Cardiovascular conditions (25% of presentations) were the most expensive (mean $11 523, total annual $148.7 million), while a non-specific pain diagnosis (49% of presentations) was the least expensive (mean $3836, total annual $93.4 million). Patients classified as being at low risk of myocardial infarction, mortality or hospital admission (Early Chest pain Admission, Myocardial infarction, and Mortality (ECAMM) score) represented 31%–57% of the cohort, with total annual costs estimated at $60.6 million–$135.4 million, depending on the score cut-off used.ConclusionsTotal annual costs for acute chest pain presentations are increasing, and a significant proportion of the cost burden relates to low-risk patients and non-specific pain. These data highlight the need to improve the cost-efficiency of chest pain care pathways.

General Medicine ,Pathology and Forensic Medicine - Abstract
The mouse double minute 2 (MDM2) gene is located on the long arm of chromosome 12 and is the primary negative regulator of p53. TheMDM2gene encodes an E3 ubiquitin–protein ligase that mediates the ubiquitination of p53, leading to its degradation. MDM2 enhances tumour formation by inactivating the p53 tumour suppressor protein. The MDM2 gene also has many p53-independent functions. Alterations ofMDM2may occur through various mechanisms and contribute to the pathogenesis of many human tumours and some non-neoplastic diseases. Detection ofMDM2amplification is used in the clinical practice setting to help diagnose multiple tumour types, including lipomatous neoplasms, low-grade osteosarcomas and intimal sarcoma, among others. It is generally a marker of adverse prognosis, and MDM2-targeted therapies are currently in clinical trials. This article provides a concise overview of theMDM2gene and discusses practical diagnostic applications pertaining to human tumour biology.

Neurology (clinical) ,General Medicine - Abstract
Shoulder pain is common after neurological injury and can be disabling, lead to poor functional outcomes and increase care costs. Its cause is multifactoral and several pathologies contribute to the presentation. Astute diagnostic skills and a multidisciplinary approach are required to recognise what is clinically relevant and to implement appropriate stepwise management. In the absence of large clinical trial data, we aim to provide a comprehensive, practical and pragmatic overview of shoulder pain in patients with neurological conditions. We use available evidence to produce a management guideline, taking into account specialty opinions from neurology, rehabilitation medicine, orthopaedics and physiotherapy.

ObjectiveTo compare the effect of early surgery versus exercise and education on mechanical symptoms and other patient-reported outcomes in patients aged 18–40 years with a meniscal tear and self-reported mechanical knee symptoms.MethodsIn a randomised controlled trial, 121 patients aged 18–40 years with a MRI-verified meniscal tear were randomised to surgery or 12-week supervised exercise and education. For this study, 63 patients (33 and 30 patients in the surgery and in the exercise group, respectively) reporting baseline mechanical symptoms were included. The main outcome was self-reported mechanical symptoms (yes/no) at 3, 6 and 12 months assessed using a single item from the Knee Injury and Osteoarthritis Outcome Score (KOOS). Secondary outcomes were KOOS4and the 5 KOOS-subscales and the Western Ontario Meniscal Evaluation Tool (WOMET).ResultsIn total, 55/63 patients completed the 12-month follow-up. At 12 months, 9/26 (35%) in the surgery group and 20/29 (69%) in the exercise group reported mechanical symptoms. The risk difference and relative risk at any time point was 28.7% (95% CI 8.6% to 48.8%) and 1.83 (95% CI 0.98 to 2.70) of reporting mechanical symptoms in the exercise group compared with the surgery group. We did not detect any between-group differences in the secondary outcomes.ConclusionThe results from this secondary analysis suggest that early surgery is more effective than exercise and education for relieving self-reported mechanical knee symptoms, but not for improving pain, function and quality of life in young patients with a meniscal tear and mechanical symptoms.Trial registration numberNCT02995551.

BackgroundPatients experiencing early pregnancy loss often first present to the emergency department (ED) where they can be managed non-operatively through expectant or medical management, or surgically by the obstetrical team. Studies have reported that physician gender can influence clinical decision making, but there is limited research on this phenomenon in the ED. The objective of this study was to determine whether emergency physician gender is associated with early pregnancy loss management.MethodsData were retrospectively collected from patients who presented to Calgary EDs with a non-viable pregnancy from 2014 to 2019. Pregnancies>12 weeks gestational age were excluded. The emergency physicians included saw at least 15 cases of pregnancy loss over the study period. The primary outcome was obstetrical consult rates by male versus female emergency physicians. Secondary outcomes included rates of initial surgical evacuation via dilation and curettage (D&C) procedures, ED returns, returns to care for D&Cs and total D&C rates. Data were analysed using χ2, Fisher’s exact and Mann-Whitney U tests, as appropriate. Multivariable logistic regression models accounted for physician age, years of practice, training programme and type of pregnancy loss.Results98 emergency physicians and 2630 patients from 4 ED sites were included. 76.5% of the physicians were male accounting for 80.4% of pregnancy loss patients. Patients seen by female physicians were more likely to receive an obstetrical consultation (adjusted OR (aOR) 1.50, 95% CI 1.22 to 1.83) and initial surgical management (aOR 1.35, 95% CI 1.08 to 1.69). ED return rates and total D&C rates were not associated with physician gender.ConclusionPatients seen by female emergency physicians had higher rates of obstetrical consultation and initial operative management compared with those seen by male emergency physicians, but outcomes were similar. Additional research is required to determine why these gender differences exist and how these discrepancies may impact the care of early pregnancy loss patients.

Emergency Medicine ,General Medicine ,Critical Care and Intensive Care Medicine - Abstract
BackgroundPoint-of-care (POC) lung ultrasound (LUS) is widely used in the emergency setting and there is an established evidence base across a range of respiratory diseases, including previous viral epidemics. The necessity for rapid testing combined with the limitations of other diagnostic tests has led to the proposal of various potential roles for LUS during the COVID-19 pandemic. This systematic review and meta-analysis focused specifically on the diagnostic accuracy of LUS in adult patients presenting with suspected COVID-19 infection.MethodsTraditional and grey-literature searches were performed on 1 June 2021. Two authors independently carried out the searches, selected studies and completed the Quality Assessment Tool for Diagnostic Test Accuracy Studies (QUADAS-2). Meta-analysis was carried out using established open-source packages inR. We report overall sensitivity, specificity, positive and negative predictive values, and the hierarchical summary receiver operating characteristic curve for LUS. Heterogeneity was determined using the I2statistic.ResultsTwenty studies were included, published between October 2020 and April 2021, providing data from a total of 4314 patients. The prevalence and admission rates were generally high across all studies. Overall, LUS was found to be 87.2% sensitive (95% CI 83.6 to 90.2) and 69.5% specific (95% CI 62.2 to 72.5) and demonstrated overall positive and negative likelihood ratios of 3.0 (95% CI 2.3 to 4.1) and 0.16 (95% CI 0.12 to 0.22), respectively. Separate analyses for each reference standard revealed similar sensitivities and specificities for LUS. Heterogeneity was found to be high across the studies. Overall, the quality of studies was low with a high risk of selection bias due to convenience sampling. There were also applicability concerns because all studies were undertaken during a period of high prevalence.ConclusionDuring a period of high prevalence, LUS had a sensitivity of 87% for the diagnosis of COVID-19 infection. However, more research is required to confirm these results in more generalisable populations, including those less likely to be admitted to hospital.PROSPERO registration numberCRD42021250464

ObjectivesTo describe the range of collaborative approaches to shared decision-making (SDM) observed in clinical encounters of patients with diabetes and their clinicians.DesignA secondary analysis of videorecordings obtained in a randomised trial comparing usual diabetes primary care with or without using a within-encounter conversation SDM tool.SettingUsing the purposeful SDM framework, we classified the forms of SDM observed in a random sample of 100 video-recorded clinical encounters of patients with type 2 diabetes in primary care.Main outcome measuresWe assessed the correlation between the extent to which each form of SDM was used and patient involvement (OPTION12-scale).ResultsWe observed at least one instance of SDM in 86 of 100 encounters. In 31 (36%) of these 86 encounters, we found only one form of SDM, in 25 (29%) two forms, and in 30 (35%), we found ≥3 forms of SDM. In these encounters, 196 instances of SDM were identified, with weighing alternatives (n=64 of 196, 33%), negotiating conflicting desires (n=59, 30%) and problemsolving (n=70, 36%) being similarly prevalent and developing existential insight accounting for only 1% (n=3) of instances. Only the form of SDM focused on weighing alternatives was correlated with a higher OPTION12-score. More forms of SDM were used when medications were changed (2.4 SDM forms (SD 1.48) vs 1.8 (SD 1.46); p=0.050).ConclusionsAfter considering forms of SDM beyond weighing alternatives, SDM was present in most encounters. Clinicians and patients often used different forms of SDM within the same encounter. Recognising a range of SDM forms that clinicians and patients use to respond to problematic situations, as demonstrated in this study, opens new lines of research, education and practice that may advance patient-centred, evidence-based care.

Neurology (clinical) ,General Medicine - Abstract
Posterior spinal artery syndrome has a variable presentation and often poses a clinical challenge. We describe an acute posterior spinal artery syndrome in a man in his 60s with vascular risk factors, who presented with altered sensation in the left arm and left side of his torso but with normal tone, strength and deep tendon reflexes. MR imaging showed a left paracentral T2 hyperintense area affecting the posterior spinal cord at the level of C1. Diffusion-weighted MRI (DWI) showed high signal intensity in the same location. He was medically managed as having ischaemic stroke and made a good recovery. Three-month MRI follow-up showed a persisting T2 lesion but the DWI changes had resolved, consistent with the time course for infarction. Posterior spinal artery stroke has a variable presentation and is probably under-recognised clinically, requiring careful attention to MR imaging for its diagnosis.

People who use or sell drugs develop their own in-group terms and language, much like any other group of people with a common experience. Slang terms are derived from a wide variety of sources. These might include the physical appearance and/or type of drug, the place where it originates, the effect it has on users, or how it is packaged for sale. To assist and educate the clinical practitioner who may deal with this nomenclature, we have compiled a list of some of the most common street names and some explanations (when known) of their origins.

This review summarises the long period in which man has approached nature to understand its powers, and has tried to control it through physical and chemical, and also magical, practices. From the attempt to manage nature to the development of primordial drugs and medical practices and later to achieve modern biomedical science, laboratory practices always played a pivotal role. Over the years and centuries, the laboratory has acquired more and more importance in the improvement of health.In addition to the well-known importance of laboratory medicine in the early diagnosis and appropriateness, the discoveries of the last 50 years have also given the Laboratory a decisive role in regenerative and personalised medicine.This paper examines the evolution of the laboratory and is not meant to be a treatise on the history of medicine. The goal is to highlight the moments of the transition from magic and alchemy to laboratory science.-------------------------------Roberto Verna is President of the World Association of Societies of Pathology and Laboratory Medicine and President of the Academy for Health and Clinical Research.

ObjectiveTo map the current literature evaluating the diagnosis and treatment of multiligament knee injuries (MLKIs).DesignScoping review.Data sourcesPreferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews and Arksey and O’Malley frameworks were followed. A three-step search strategy identified relevant published literature comprising studies reporting on at least one aspect in the diagnosis or treatment of MLKI in adults. Data were synthesised to form a descriptive analysis and thematic summary.ResultsOverall, 417 studies were included. There was a substantial chronological increase in the number of studies published per year, with 70% published in the last 12 years. Of included studies, 128 (31%) were narrative reviews, editorials or technical notes with no original data. The majority of studies (n=239, 57%) originated from the USA; only 4 studies (1%) were of level I evidence. Consistent themes of contention included clinical assessment, imaging, operative strategy, timing of surgery and rehabilitation. There was a lack of gender and ethnic diversity reported within patient groups.ConclusionsThere remains insufficient high-level evidence to support definitive management strategies for MLKI. There is considerable heterogeneity in outcome reporting in current MLKI literature, precluding robust comparison, interpretation and pooling of data. Further research priorities include the development of expert consensus relating to the investigation, surgical management and rehabilitation of MLKI. There is a need for minimum reporting standards for clinical studies evaluating MLKI.

General Medicine ,Pathology and Forensic Medicine - Abstract
Ki67 expression is one of the most important and cost-effective surrogate markers to assess for tumour cell proliferation in breast cancer (BC). The Ki67 labelling index has prognostic and predictive value in patients with early-stage BC, particularly in the hormone receptor-positive, HER2 (human epidermal growth factor receptor 2)-negative (luminal) tumours. However, many challenges exist in using Ki67 in routine clinical practice and it is still not universally used in the clinical setting. Addressing these challenges can potentially improve the clinical utility of Ki67 in BC. In this article, we review the function, immunohistochemical (IHC) expression, methods for scoring and interpretation of results as well as address several challenges of Ki67 assessment in BC. The prodigious attention associated with use of Ki67 IHC as a prognostic marker in BC resulted in high expectation and overestimation of its performance. However, the realisation of some pitfalls and disadvantages, which are expected with any similar markers, resulted in an increasing criticism of its clinical use. It is time to consider a pragmatic approach and weigh the benefits against the weaknesses and identify factors to achieve the best clinical utility. Here we highlight the strengths of its performance and provide some insights to overcome the existing challenges.

General Medicine ,Pathology and Forensic Medicine - Abstract
Resections of ischaemic bowel are one of the most common pathology specimens yet are often viewed as unappealing and diagnostically unrewarding. This article serves to dispel both misconceptions. It also provides guidance on how clinical information, macroscopic handling and microscopic assessment—and especially the interlinking of all three—can maximise the diagnostic yield of these specimens. This diagnostic process requires recognition of the wide range of causes of intestinal ischaemia, including several more recently described entities. Pathologists should also be aware of when and why such causes cannot be discerned from a resected specimen and of how certain artefacts or differential diagnoses can mimic ischaemia.

Neurology (clinical) ,General Medicine - Abstract
Recreational use of nitrous oxide (N2O) has increased rapidly in recent years and is now the second most commonly used recreational drug among young people in the UK. There has been a corresponding rise in cases of nitrous oxide-induced subacute combined degeneration of the cord (N2O-SACD), a pattern of myeloneuropathy usually associated with severe vitamin B12deficiency. This can cause serious and permanent disability in young people but, if recognised early, may be effectively treated. All neurologists should be aware of N2O-SACD and its treatment; however, there are currently no agreed guidelines. Based on our experience in East London, an area of high N2O use, we provide practical advice on its recognition, investigation and treatment.

ObjectiveTo compare the short-term, mid-term and long-term effects between three interventions (education only, education and strengthening exercises, education and motor control exercises) for rotator cuff-related shoulder pain (RCRSP) on symptoms and function.Methods123 adults presenting with RCRSP took part in a 12-week intervention. They were randomly assigned to 1 of 3 intervention groups. Symptoms and function were evaluated at baseline and at 3 weeks, 6 weeks, 12 weeks and 24 weeks using the Disability of Arm, Shoulder and Hand Questionnaire (QuickDASH) (primary outcome) and Western Ontario Rotator Cuff Index (WORC). Linear mixed modelling was used to compare the effects of the three programmes on the outcomes.ResultsAfter 24 weeks, between-group differences were −2.1 (-7.7 to 3.5) (motor control vs education), 1.2 (-4.9 to 7.4) (strengthening vs education) and −3.3 (-9.5 to 2.8) (motor control vs strengthening) for theQuickDASH and 9.3 (1.5 to 17.1) (motor control vs education), 1.3 (−7.6 to 10.2) (strengthening vs education) and 8.0 (−0.5 to 16.5) (motor control vs strengthening) for the WORC. There was a significant group-by-time interaction (p=0.04) withQuickDASH, but follow-up analyses did not reveal any clinically meaningful between-group differences. There was no significant group-by-time interaction (p=0.39) for the WORC. Between-group differences never exceeded the minimal clinically important difference ofQuickDASH or WORC.ConclusionIn people with RCRSP, the addition of motor control or strengthening exercises to education did not lead to larger improvements in symptoms and function compared with education alone. Further research should investigate the value of providing stepped care by identifying individuals who may only need education and those who would benefit from the addition of motor control or strengthening exercises.Trial registration numberNCT03892603.

Emergency Medicine ,General Medicine ,Critical Care and Intensive Care Medicine - Abstract
BackgroundBenign paroxysmal positional vertigo (BPPV) is a common presentation to the ED. Evidence suggests low adherence to guideline-recommended care, but the reasons underlying this are poorly understood. This study used the theoretical domains framework (TDF) to explore the barriers and facilitators to medical and physiotherapy clinical practices in the management of BPPV in an Australian metropolitan ED.MethodsFrom May to December 2021, semistructured interviews were conducted with 13 medical staff and 13 physiotherapists who worked at an ED in Melbourne, Australia. Interviews used the TDF to explore the perceived barriers and facilitators to the delivery of guideline-recommended assessment and treatment techniques for BPPV. Data were analysed thematically to identify relevant domains and generate themes and belief statements.ResultsFifteen belief statements representing eight domains of the TDF were identified as key factors in the management of BPPV in the ED. The most prominent domains wereknowledgeandskillsdue to their conflicting belief statements between professions concerning education, skill development and self-confidence;memory, attention and decision processesfor the perceived complexity of the presentation including difficulty recalling diagnostic and treatment techniques; andenvironmental context and resourcesfor their shared belief statements concerning time and workload pressures. The availability of vestibular physiotherapy was considered both a barrier and facilitator to the delivery of recommended care by medical staff, but a barrier to independent practice as it unintentionally limited the opportunities for skill development in medical staff.ConclusionSeveral modifiable barriers and facilitators to the management of BPPV in the ED have been identified. Differences were observed between the professional groups, and these findings will guide a future intervention to improve the use of guideline-recommended assessment and treatment techniques for BPPV in ED.

Emergency Medicine ,General Medicine ,Critical Care and Intensive Care Medicine - Abstract
In 2021, there was a significant increase in the number of reported drink spiking incidents across the UK. The new phenomenon of spiking via injection also emerged, which gained significant media attention. Campaigns encouraged potential spiking victims to attend an ED for testing. However, there is limited published research on drink spiking and no published studies on injection spiking. One UK guideline for the management of spiking exists, advising testing ‘if clinically indicated’ and is likely underused. Therefore, patients are often managed without drug testing, psychological support or a clear onward referral pathway. This practice review will explore the background of spiking, discuss drug testing options and highlight the psychological sequelae of spiking. An example guideline for the management of spiking incidents is attached.

BackgroundAirway management checklists have improved paediatric patient safety in some clinical settings, but consensus on the appropriate components to include on a checklist for paediatric tracheal intubation in the ED is lacking.MethodsA multidisciplinary panel of 14 experts in airway management within and outside of paediatric emergency medicine participated in a modified Delphi approach to develop consensus on the appropriate components for a paediatric airway management checklist for the ED. Panel members reviewed, modified and added to the components from the National Emergency Airway Registry for Children airway safety checklist for paediatric intensive care units using a 9-point appropriateness scale. Components with a median score of 7.0–9.0 and a 25th percentile score ≥7.0 achieved consensus for inclusion. A priori, the modified Delphi method was limited to a maximum of two rounds for consensus on essential components and one additional round for checklist creation.ResultsAll experts participated in both rounds. Consensus was achieved on 22 components. Twelve were original candidate items and 10 were newly suggested or modified items. Consensus components included the following categories: patient assessment and plan (5 items), patient preparation (5 items), pharmacy (2 items), equipment (7 items) and personnel (3 items). The components were formatted into a 17-item clinically usable checklist.ConclusionsUsing the modified Delphi method, consensus was established among airway management experts around essential components for an airway management checklist intended for paediatric tracheal intubation in the ED.

ObjectiveHomophobic language is common in male sport and associated with negative physical and mental health outcomes for all sport participants, but particularly for gay or bisexual youth populations. Evidence-based interventions are needed to reduce such language and mitigate harm. This study evaluated the effectiveness of a short social-cognitive educational intervention delivered by professional rugby union players in youth sport.MethodsIn a two-arm, cluster randomised controlled trial, 13 Australian youth rugby teams from 9 clubs (N=167, ages 16–20, mean 17.9) were randomised into intervention or control groups. Professional rugby players delivered the intervention in-person. Frequency of homophobic language use was measured 2 weeks before and 2 weeks after the intervention. Hypothesised factors underpinning homophobic language were also measured, including descriptive (other people use), prescriptive and proscriptive injunctive norms (approval/disapproval by others), and attitudes towards the acceptability of homophobic language.ResultsAt baseline, 49.1% of participants self-reported using homophobic language in the past 2 weeks and 72.7% reported teammates using homophobic language. Significant relationships were found between this behaviour and the hypothesised factors targeted by the intervention. However, generalised estimating equations found the intervention did not significantly reduce homophobic language, or alter the associated norms and attitudes, relative to controls.ConclusionUse of professional rugby athletes to deliver education on homophobic language was not effective. Other approaches to reduce homophobic language (and other forms of discrimination) such as peer-to-peer education, and enforcement of policies prohibiting specific language by coaches, should be explored.

BackgroundDisability and death due to low falls is increasing worldwide and disproportionately affects older adults. Current trauma systems were not designed to suit the needs of these patients. This study assessed the association between major trauma centre (MTC) care and outcomes in adult patients injured by low falls.MethodsData were obtained from the Trauma Audit and Research Network on adult patients injured by falls from Results127 334 patients were included, of whom 27.6% attended an MTC. The median age was 79.4 years (IQR 64.5–87.2 years), and 74.2% of patients were aged >65 years. MTC care was not associated with improved 30-day survival (adjusted OR (AOR) 0.91, 95% CI 0.87 to 0.96, p65 years (AOR 1.038, 95% CI 0.982 to 1.097, p=0.184).ConclusionMTC care was not associated with improved survival compared with TU/LEH care in the whole cohort. Patients who were transferred had a significant impact on the results. In patients who are not transferred, MTC care is associated with greater odds of 30-day survival in the whole cohort and in the most severely injured patients. Future research must determine the optimum means of identifying patients in need of higher-level care, the components of care which improve patient outcomes, develop patient-focused outcomes which reflect the characteristics and priorities of contemporary trauma patients, and investigate the need for transfer in specific subgroups of patients.

BackgroundFew studies have assessed older adult patients who received extracorporeal cardiopulmonary resuscitation (ECPR) after cardiac arrest, and outcomes and prognostic factors of ECPR in this population remain unclear. This study aimed to assess the long-term outcomes and prognostic factors among patients older than 75 years who received ECPR after experiencing cardiac arrest.MethodsThis is a single-centre, retrospective case–control study conducted between August 2010 and July 2019. Consecutive patients older than 75 years who had in-hospital (IHCA) or out-of-hospital cardiac arrest (OHCA) and received ECPR at the Emergency Department in the Hyogo Emergency Medical Center, Hyogo, Japan, were included. The primary outcome was a favourable neurological outcome, defined as a Cerebral Performance Category score of 1–2 at 1 year after the event. Univariate logistic regression was used to determine the association between variables and patient outcomes.ResultsOf the 187 patients with cardiac arrest who received ECPR, 30 were older than 75 years and 28 (15% of the cohort receiving ECPR) were examined in this study. The median age of the patients was 79 years (IQR 77–82), and there were 13 (46%) male patients. Neurological outcomes were favourable for seven (25%) patients, five of whom had IHCA and two with out-of-hospital OHCA. On univariate analysis, patients with a favourable outcome had a shorter median total collapse time (TCT) than those with an unfavourable outcome (favourable: 18.0 min (IQR 13.0–33.5) vs unfavourable: 44.0 min (IQR 25.0–53.0); p=0.049).ConclusionIn selected patients older than 75 years, ECPR could be beneficial by providing a shorter TCT, which may contribute to favourable neurological outcomes. Nevertheless, further studies are needed to validate these findings.

BackgroundUpper and lower limb (peripheral) pain is prevalent in athletes. Contemporary research prioritises multidimensional pain assessment and classification. This study aims to review comprehensive athlete pain assessment practices against the reference standard (International Olympic Committee, IOC Athlete Pain framework), identifying trends and highlighting gaps.Methods and analysisSix databases were searched using a comprehensive search strategy. This review followed the Joanna Briggs Institute standardised methodology for scoping reviews and is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Title and abstract, full-text screening and data charting were completed by two independent reviewers.Inclusion criteriaOriginal research, systematic reviews and clinical practice guidelines reporting assessment or classification of pain in athletes of any age with chronic or acute peripheral pain in English on human participants from database inception.Results470 studies with 175 different pain assessment tools were mapped against the IOC Athlete Pain Framework. Papers included tools from neurophysiological (470/100%), biomechanical (425/90%), affective (103/22%), cognitive (59/13%) and socioenvironmental (182/39%) domains. Pain classification was included in 108 studies (23%). 4 studies (0.85%) defined pain. Athletes with physical disability were included in 13 (3%) studies and no studies included athletes with intellectual disabilities. Socioeconomic factors were addressed in 29 (6%) studies.DiscussionNeurophysiological and biomechanical domains are frequently addressed. Affective, socioenvironmental and cognitive tools are under-represented. Potential tools for use by researchers and clinicians are highlighted. Defining and classifying pain and determining predominant pain mechanisms is needed in both research and clinical practice. More work on underrepresented populations is needed.ConclusionThis review informs researchers and clinicians working with athletes in pain how pain assessment and classification is currently conducted and highlights future priorities.

BackgroundPeople recently released from prison engage with emergency healthcare at greater rates than the general population. While retention in opioid agonist treatment (OAT) is associated with substantial reductions in the risk of opioid-related mortality postrelease, it is unknown how OAT affects contact with emergency healthcare. In a cohort of men who injected drugs regularly prior to imprisonment, we described rates of contact with ambulance services and EDs, and their associations with use of OAT, in the 3 months after release from prison.MethodsSelf-report data from a prospective observational cohort of men who regularly injected drugs before a period of sentenced imprisonment, recruited between September 2014 and May 2016, were linked to state-wide ambulance and ED records over a 3-month postrelease period in Victoria, Australia. We used generalised linear models to estimate associations between OAT use (none/interrupted/retained) and contact with ambulance and EDs postrelease, adjusted for other covariates.ResultsAmong 265 participants, we observed 77 ambulance contacts and 123 ED contacts over a median of 98 days of observation (IQR 87–125 days). Participants who were retained in OAT between prison release and scheduled 3-month postrelease follow-up interviews had lower rates of contact with ambulance (adjusted incidence rate ratio (AIRR) 0.33, 95% CI 0.14 to 0.76) and ED (AIRR 0.43, 95% CI 0.22 to 0.83), compared with participants with no OAT use postrelease. Participants with interrupted OAT use did not differ from those with no OAT use in rates of contact with ambulance or ED.ConclusionWe found lower rates of contact with emergency healthcare after release among people retained in OAT, but not among people reporting interrupted OAT use, underscoring the benefits of postrelease OAT retention. Strategies to improve accessibility and support OAT retention after leaving prison are important for men who inject drugs.

BackgroundDistal femur fractures account for approximately 3%–6% of all femoral fractures. Non-operative management may be an attractive option for the elderly with significant perioperative mortality risk. Adequate pain control is a major barrier to non-operative fracture management. Chemical neurolysis has been described for analgesic management of proximal hip fractures, however no description of interventional management of distal femur fracture exists in literature. We describe a case of phenol chemical neurolysis of genicular nerves in addition to injection at the site of fracture to provide effective analgesia for distal femur fracture.Case presentationA patient in their 90s with a witnessed mechanical fall sustained an intra-articular displaced fracture of the distal right femur shaft with extension into the distal femoral condyle. The patient elected to undergo non-surgical management given the high perioperative mortality risk. Acute pain service was involved and multimodal oral analgesics including opioids were insufficient in managing the patient’s pain. The addition of femoral nerve catheter local anesthetic infusion did not sufficiently improve analgesia. Phenol chemical neurolysis of the superolateral, superomedial, inferomedial genicular nerves and of the fracture site was offered and performed. Resting pain decreased from Numerical Rating Scale 5/10 to 0/10 on postprocedure day 1. This was sustained at the 2-month timepoint.ConclusionsWe report the successful use of phenol neurolysis of genicular nerves and the fracture site in an elderly patient with a conservatively managed distal femur fracture. These interventions resulted in improved analgesia and achieved prolonged duration of effect.

Neurology (clinical) ,General Medicine - Abstract
The introduction of calcitonin gene-related peptide monoclonal antibodies represents a step forward in preventive migraine treatment as the first agents to target the underlying pathogenesis of migraine. In trials they act more quickly, have better long-term adherence and appear to be better tolerated than other treatments. Major disadvantages are their high cost and unknown safety in pregnancy and in cardiovascular disease. To mitigate these concerns, they should be used according to guidance produced by professional bodies, with defined starting and stopping criteria. We do not yet know whether they are more effective than standard care; many patients may still be better treated by other means, in particular addressing lifestyle factors and medication-overuse headache.
