Treating Obsessive Compulsive Disorder in Adolescents and Adults with Down Syndrome: Results from a Scoping Rapid Review

PURPOSE

Adolescents and adults with Down syndrome are noted to display symptoms and behaviors consistent with a diagnosis of Obsessive Compulsive Disorder. While evidenced-based interventions, including psychopharmacology and therapeutic interventions including exposure and response prevention, exist and effectively treat obsessive-compulsive symptoms in neurotypical populations, less is known about effective treatments for similar presentations in persons with Down syndrome.

METHODS

A scoping rapid review was conducted in April 2023 to determine what treatments are being used to target obsessive-compulsive symptoms and related behaviors in adolescents and adults with Down syndrome, the quality of those treatments, and their alignment with current evidenced-based interventions.

RESULTS

A total of eleven articles, all single case or case series, published between 1992 and 2017 were identified describing the treatment of 32 adolescents and adults with Down syndrome and obsessive-compulsive traits and behaviors including: hoarding, cleaning, gross motor compulsions, and food, hygiene, dressing, and checking rituals. Interventions used most often aligned with evidenced-based guidelines for treating obsessive compulsive disorder and included psychopharmacology, psychotherapy, and complementary and alternative medicine.

CONCLUSIONS

While the outcomes of most interventions yielded partial or significant reduction in symptoms, poor research quality and limited generalizability noted across all studies make it difficult to inform guidelines for caring for this high-needs population. In the future, we believe it is necessary to perform more rigorous research focused on treating obsessive compulsive symptoms in individuals with Down syndrome with sufficient follow-up to fully assess treatment effectiveness.

Are military fitness tests safe for members with a total hip arthroplasty?

INTRODUCTION

Canadian Armed Forces (CAF) members must complete an annual fitness evaluation. Members with a total hip arthroplasty (THA) may be at risk of injury during these strenuous tests. To inform CAF policy, we sought expert consensus on the safety of fitness testing for members with a THA.

METHODS

We conducted a three-round Delphi study with a panel of hip arthroplasty experts to determine the safety of CAF operational fitness evaluations for members with a THA. The experts evaluated videos of the 10 individual tasks included in the evaluations.

RESULTS

All individual tasks were judged to be safe by consensus. One task, which involves digging with a shovel, was considered safe provided that participants avoid deep hip flexion. The nine other tasks were judged to be safe without modifications or interventions. The experts also supported a policy recommendation that would allow members to perform military fitness evaluations if they (1) have a primary THA, (2) had no episodes of instability, (3) are at least 12 months postoperatively and (4) have been cleared by an orthopaedic surgeon and a physiatrist/physiotherapist.

CONCLUSION

A panel of arthroplasty experts concluded, based on video analysis, that CAF fitness evaluations are generally safe for members with a THA.

Bathing Adaptations in the Homes of Older Adults (BATH-OUT-2): study protocol for a randomised controlled trial, economic evaluation and process evaluation

BACKGROUND

The onset of disability in bathing is particularly important for older adults as it can be rapidly followed by disability in other daily activities; this may represent a judicious time point for intervention in order to improve health, well-being and associated quality of life. An important environmental and preventative intervention is housing adaptation, but there are often lengthy waiting times for statutory provision. In this randomised controlled trial (RCT), we aim to evaluate the effectiveness and cost-effectiveness of bathing adaptations compared to no adaptations and to explore the factors associated with routine and expedited implementation of bathing adaptations.

METHODS

BATH-OUT-2 is a multicentre, two-arm, parallel-group RCT. Adults aged 60 and over who are referred to their local authority for an accessible level access shower will be randomised, using pairwise randomisation, 1:1, to receive either an expedited provision of an accessible shower via the local authority or a usual care control waiting list. Participants will be followed up for a maximum of 12 months and will receive up to four follow-ups in this duration. The primary outcome will be the participant's physical well-being, assessed by the Physical Component Summary score of the Short Form-36 (SF-36), 4 weeks after the intervention group receives the accessible shower. The secondary outcomes include the Mental Component Summary score of the SF-36, self-reported falls, health and social care resource use, health-related quality of life (EQ-5D-5L), social care-related quality of life (Adult Social Care Outcomes Toolkit (ASCOT)), fear of falling (Short Falls Efficacy Scale), independence in bathing (Barthel Index bathing question), independence in daily activities (Barthel Index) and perceived difficulty in bathing (0-100 scale). A mixed-methods process evaluation will comprise interviews with stakeholders and a survey of local authorities with social care responsibilities in England.

DISCUSSION

The BATH-OUT-2 trial is designed so that the findings will inform future decisions regarding the provision of bathing adaptations for older adults. This trial has the potential to highlight, and then reduce, health inequalities associated with waiting times for bathing adaptations and to influence policies for older adults.

Inadequate neuraxial anaesthesia during caesarean delivery: a survey of practitioners

BACKGROUND

We aimed to determine the knowledge, training, practices and attitudes of obstetric anaesthetic practitioners with regard to failed neuraxial anaesthesia for caesarean delivery.

METHOD

We performed a contemporaneous and representative survey in an innovative fashion. We conducted an international cross-sectional study of obstetric anaesthetic practitioners at the Annual Scientific Meeting of the Obstetric Anaesthetists' Association (OAA 2021). Validated survey questions were collected in real time using an audience response system.

RESULTS

Of the 426 participants who logged into the survey system, 356 provided responses (4173 responses to 13 questions, across all grades/seniority of practitioner). The number of responses to questions ranged from 81% to 61%. Survey responses suggest that it is routine for respondents to inform patients about the difference between pain and expected intra-operative sensations, (320/327, 97.9%) but less routine to inform patients of the risk of intra-operative pain (204/260, 78.5%), or the possibility of conversion to general anaesthesia. (290/309 93.8%). Only 30% of respondents reported the use of written guidelines for follow-up of patients who experience intra-operative pain under neuraxial anaesthesia, and only 23% reported formal training in management of intra-operative pain under neuraxial anaesthesia. Respondents felt that inadequate block duration, prolonged surgery, and patient anxiety were contributory factors to failed anaesthesia, and the contributory factors differed between grade/seniority of practitioner. Modalities used to test a block were cold, motor block and light touch, with approximately 65% of respondents routinely using three modalities.

CONCLUSIONS

Our study survey found that the consent process may not always be adequately comprehensive, and that standardised documentation and testing of the block and focused training may be beneficial to prevent patient dissatisfaction and the chance of litigation.

The Hidden Economic Consequences of Migraine to the UK Government: Burden-of-Disease Analysis Using a Fiscal Framework

Background: Migraine is a highly prevalent and incapacitating neurological disorder associated with the highest global disability burden in people aged 15 to 49 years. Europe has the fourth-highest prevalence of migraine, after North America, South America, and Central America, and above Asia and Africa. Migraine leads to relatively modest direct healthcare expenditure but has substantial indirect costs due to reduced productivity. Methods: The economic burden of migraine was estimated in comparison with the general population of the United Kingdom (UK) using an analytical fiscal modeling framework applying the government cost perspective. Published measures of migraine's impact on labor participation were applied to rates of economic activity/inactivity of the general population. The model estimates lifetime changes to earnings from employment, direct and indirect taxes paid, and financial support requirements over the life course. Incremental differences between those affected and unaffected by migraine are reported as net fiscal consequences to public accounts. Fiscal costs are reported as the discounted average per capita over a 20-year time horizon and for the entire annual UK cohort with prevalent migraine. Results: People affected by migraine are more likely to be absent from work, unemployed, and disabled, and to retire early. A 44-year-old individual affected by migraine was associated with £19 823 in excess fiscal costs to the UK government, £1379 per year living with the condition, compared with someone not affected by the disease. Annually, migraine was estimated to represent £12.20 billion to the public economy, approximately £130.63 per migraine episode. The model predicted annual productivity losses in the health and social care workforce to be £2.05 billion and total annual productivity losses to be over £5.81 billion. Conclusions: This fiscal analysis monetizes the occupational consequences of migraine to the UK government, both in terms of lost tax revenue and transfer payments. The findings are substantial and useful to characterize disease severity and to inform the body of evidence considered by decision makers appraising the cost-effectiveness of health technologies.

Four-dimensional ultrasound guided embryo transfers improve live birth rates when compared to the clinical touch technique: a randomised controlled trial

Most aspects of in-vitro fertilisation (IVF) have changed dramatically since introduction, but embryo transfer (ET) technique remains largely unaltered. We aimed to determine whether four-dimensional ultrasound guided embryo transfers (4D UGET) could improve pregnancy rates when compared with clinical touch technique (CTT). This was a single centre open labelled randomised controlled trial in a tertiary fertility centre in the UK. 320 women were randomised on the day of single ET. The primary outcome was clinical pregnancy rate (CPR), secondary outcomes included live birth rate (LBR), biochemical pregnancy rate (BPR), miscarriage, pregnancy of unknown location (PUL) and ectopic pregnancy. 4D-UGET resulted in significantly higher CPR [50% vs 36% p = 0.02, OR 1.78 (1.12-2.84)] and LBR [41% vs 28%, p = 0.02, OR 1.77 (1.09-2.87)] when compared to CTT technique. Miscarriage (p = 0.49), PUL (p = 0.14) and ectopic pregnancy (p = 0.96) were similar between the two groups. LBR, from this trial, are significantly higher than the current UK average (41% vs 24%). 4D UGET allows for superior imaging of the uterine cavity, whilst tailoring the embryo deposition point specifically to the patient. Further RCTs are required to determine if these results can be replicated in other units and whether 4D UGET is superior to 2D UGET.

Quantifying the burden of persistent musculoskeletal pain in employees at Rolls-Royce in the United Kingdom: a real-world cross-sectional survey

OBJECTIVE

We aimed to investigate the burden of persistent musculoskeletal (MSK) pain in Rolls-Royce UK employees.

METHODS

Employees with (n = 298) and without (n = 329) persistent MSK pain completed a cross-sectional survey. Weighted regression analyses were conducted to compare sickness absence, work ability, workplace accommodations/adaptations and emotional well-being between these cohorts, controlling for confounders.

RESULTS

Persistent MSK pain (particularly back pain) had a significant impact on physical work ability, and was associated with increased sickness absence due to pain. Many employees (56%) had not disclosed their condition to their managers. Of these, 30% felt uncomfortable doing so, and 19% of employees reported insufficient support at work for their pain.

CONCLUSIONS

These findings highlight the importance of creating a workplace culture that encourages the disclosure of work-relevant pain, enabling organisations to consider improved, tailored support for employees.

The delivery of obstetric anaesthetic care in UK maternity units: a survey of practice in 2021

BACKGROUND

Anaesthetists are crucial members of the maternity unit team, providing peri-operative analgesia and anaesthesia, and supporting the delivery of medical care to high-risk women. The effective contribution from obstetric anaesthetists to safety in maternity units depends on how anaesthesia services are organised and resourced. There is a lack of information on how obstetric anaesthetic care is resourced in the UK.

METHODS

The Obstetric Anaesthetists' Association surveyed UK clinical leads for their hospital's obstetric anaesthetic service and examined compliance with national recommendations.

RESULTS

There were 153 responses by lead obstetric anaesthetists from 184 maternity units in the UK (83%). The number of consultants per 1000 deliveries was 2.2 [1.6-2.7] (median [IQR]). In 20% of units, there was a dedicated on-call rota (on-call only for obstetric anaesthesia), whilst the remainder had a 'combined' on-call rota (on-call for other clinical areas in addition to obstetrics). Multidisciplinary ward rounds were held in 83% of units. Twenty-five (16%) units reported having no regular multidisciplinary ward rounds, of which nine (6%) did not have any multidisciplinary ward rounds. Planned operating lists for elective caesarean sections were provided in 77% of units.

CONCLUSIONS

In the largest survey of obstetric anaesthesia workload to be reported for any health system, we found significant disparities between obstetric anaesthesia service provision and current national recommendations for areas including consultant staffing, support for elective caesarean section lists, antenatal anaesthetic clinics, and consultant support for service development. Wide national variation in service provision was identified.

Acute Worsening of Atypical Parkinson's Syndrome After Receiving Second Dose of Moderna COVID-19 Vaccine

INTRODUCTION

Atypical Parkinson's syndromes are a rare set of neurodegenerative conditions in which a patient experiences the typical symptoms of Parkinson's disease, in addition to various other unrelated issues.

CASE PRESENTATION

We present the case of a 71-year-old White man with a 1-year history of weakness and upper extremity tremors that, per patient report, rapidly worsened after receiving the second dose of the Moderna COVID-19 vaccine. His symptoms were consistent with an asymmetric atypical Parkinson's disease, with electromyogram results indicating chronic motor neuron involvement.

DISCUSSION

There have been multiple reports of deterioration in patients with Parkinson's disease and atypical Parkinson's syndromes in response to contracting COVID-19. However, there are few, if any, case reports that describe an acute change in Parkinson-related symptoms in association with the COVID-19 vaccines.

CONCLUSIONS

As the pandemic continues, we must continue to remain vigilant as we learn more about the long-lasting effects of the virus and vaccines.

The Utility of Monitoring Potassium in Transgender, Gender Diverse and Non-binary Individuals on Spironolactone

Introduction

Current Endocrine Society guidelines recommend that transgender women taking spironolactone have their potassium levels checked every 3 months for the first year after initiating therapy and annually thereafter to monitor for hyperkalemia. The goal of this study was to assess the need for such frequent potassium monitoring and to investigate whether age plays a role in potassium abnormalities in transgender, gender diverse and non-binary (TGDNB) individuals taking spironolactone.

Methods

Using EPIC-Clarity, a retrospective study of healthy, adult individuals with gender identity disorder listed in their problem list and taking spironolactone was performed. We analyzed incidence of hyperkalemia in this population. Data from June 2006 through November 2021 were obtained. Exclusion criteria included: hypertension, renal failure, diabetes mellitus, heart failure and medications that affect the renin-angiotensin-aldosterone system.

Results

318 healthy TGDNB individuals met our inclusion criteria. We identified 8/318 (2.5%) individuals with hyperkalemia on spironolactone. There was a significant difference in incidence of hyperkalemia events in those age >45 years and those age ≤45 years old (8.9% vs. 1.5%, p= 0.016).

Conclusion

Our data suggest the incidence of hyperkalemia in our TGDNB population is low, particularly in those ≤45 years old; however, this risk increases with age. These findings suggest practice guidelines may need to be adjusted to minimize unnecessary testing in this population ≤45 years old who are not plagued by co-morbidities that affect potassium handling.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Prevention and management of intra-operative pain during caesarean section under neuraxial anaesthesia: a technical and interpersonal approach

A woman who experiences pain during caesarean section under neuraxial anaesthesia is at risk of adverse psychological sequelae. Litigation arising from pain during caesarean section under neuraxial anaesthesia has replaced accidental awareness under general anaesthesia as the most common successful medicolegal claim against obstetric anaesthetists. Generic guidelines on caesarean section exist, but they do not provide specific recommendations for this area of anaesthetic practice. This guidance aims to offer pragmatic advice to support anaesthetists in caring for women during caesarean section. It emphasises the importance of non-technical skills, offers advice on best practice and aims to encourage standardisation. The guidance results from a collaborative effort by anaesthetists, psychologists and patients and has been developed to support clinicians and promote standardisation of practice in this area.

Quantifying the Employer Burden of Persistent Musculoskeletal Pain at a Large Employer in the United Kingdom: A Non-interventional, Retrospective Study of Rolls-Royce Employee Data

OBJECTIVE

To quantify the burden of work-relevant persistent musculoskeletal (MSK) pain to a large UK employer.

METHODS

A retrospective, longitudinal, analytical cohort study using linked Rolls-Royce data systems. Cases were employees with a MSK-related referral to occupational health; controls were age-, sex-, and job role-matched employees without such a referral. Outcomes were compared during 12 months' follow-up.

RESULTS

Overall, 2382 matched case-control pairs were identified (mean age: 46 y; 82% male). Cases took 39,200 MSK-related sickness absence days in total (equating to £50 million in sickness absence costs). Cases took significantly more all-cause sickness absence days than controls (82,341 [£106 million] versus 19,628 [£26 million]; P < 0.0001).

CONCLUSIONS

Despite access to extensive occupational health services, the burden of work-relevant persistent MSK pain remains high in Rolls-Royce. There is a clear need to better understand how to effectively reduce this burden.

Risk of unplanned healthcare utilization in postpartum period for patients with hypertensive disorders of pregnancy

OBJECTIVE

To determine which factors are associated with unplanned postpartum healthcare utilization, including hospital readmission and unplanned outpatient and emergency room visits, in patients with hypertensive disorders of pregnancy (HDP).

STUDY DESIGN

This was a case control study of patients with HDP delivering at a single academic institution from 2014 through 2018. The diagnosis of HDP included chronic hypertension, gestational hypertension, preeclampsia and superimposed preeclampsia. Using bivariate and multivariate analysis, demographic and clinical characteristics were compared between patients who had unplanned healthcare utilization, defined as readmission to the hospital, emergency room visit or unplanned outpatient encounter in the first 6-weeks postpartum, and those patients who did not.

RESULTS

Of the 1427 patients with HDP included in this analysis, 174 (12.2%) had unplanned postpartum healthcare utilization. Maternal non-Hispanic Black race and ethnicity and presence of mild blood pressures on the day of discharge after delivery were associated with higher odds of unplanned healthcare utilization (aOR 1.67, 95% CI 1.08 - 2.56 and aOR 1.59, 95% CI 1.12 - 2.27, respectively). In contrast, presence of chronic hypertension was associated with lower odds of unplanned postpartum healthcare utilization (aOR 0.47, 95% CI 0.28 - 0.79) CONCLUSION: Among postpartum patients with HDP, non-Hispanic Black race and ethnicity and discharge home with mild range blood pressures were associated with higher odds of unplanned healthcare utilization in the first 6 weeks postpartum, while chronic hypertension was associated with lower odds.

Optogenetic Inhibition of Nav1.8 Expressing Corneal Afferents Reduces Persistent Dry Eye Pain

Purpose

The aim of the present study was to investigate the contribution of Nav1.8 expressing corneal afferent neurons to the presence of ongoing pain in lacrimal gland excision (LGE)-induced dry eye.

Methods

The proton pump archaerhodopsin-3/eGFP (ArchT/eGFP) was conditionally expressed in corneal afferents using Nav1.8-cre mice. Dry eye was produced by unilateral LGE. Real time place preference was assessed using a three-chamber apparatus. A neutral, unlit center chamber was flanked by one illuminated with a control light and one illuminated with an ArchT activating light. For real-time preference, animals were placed in the neutral chamber and tracked over five 10-minute sessions, with the lights turned on during the second and fourth sessions. In other studies, movement was tracked over three 10-minute sessions (the lights turned on only during the second session), with animals tested once per day over the course of 4 days. A local anesthetic was used to examine the role of ongoing corneal afferent activity in producing place preference.

Results

The corneal afferent nerves and trigeminal ganglion cell bodies showed a robust eGFP signal in Nav1.8-cre;ArchT/eGFP mice. After LGE, Nav1.8-cre;ArchT/eGFP mice demonstrated a preference for the ArchT activating light paired chamber. Preference was prevented with pre-application to the cornea of a local anesthetic. Nav1.8-cre;ArchT/eGFP mice with sham surgery and LGE wild-type control mice did not develop preference.

Conclusions

Results indicate LGE-induced persistent, ongoing pain, driven by Nav1.8 expressing corneal afferents. Inhibition of these neurons represents a potential strategy for treating ongoing dry eye-induced pain.

O-181 4D ultrasound guided embryo transfers statistically improve live birth rates - A randomised controlled trial

Study question

Does the use of 4D ultrasound to guide embryo transfers improve live birth rates in comparison to the clinical touch technique?

Summary answer

4D ultrasound guided embryo transfers (4DUS) result in significantly higher live birth rates (LBR) in comparison to those performed using the clinical touch technique (CTT)(41%vs28%).

What is known already

A previous Cochrane review showed ultrasound guided embryo transfers (ET) improve pregnancy outcomes in comparison to CTT; however there was a large degree of heterogeneity between the studies and the largest study in the review showed no difference between ultrasound guidance and CTT. A further study demonstrated no difference in ongoing pregnancy rates between 2D vs 3D ultrasound guided embryo transfers, however this study did not use LBR as an endpoint and did not report on procedure duration/difficultly, both of which are known to impact ET success rates.

Study design, size, duration

This was a prospective, open labelled randomised controlled trial comparing superiority between two techniques for ET (4DUS vs CTT). A total of 320 (n = 160/group) patients were recruited using computer generated randomisation that were centrally distributed in consecutive sealed opaque envelopes between July 2018 to December 2019. Main outcomes were clinical pregnancy rate (CPR) and LBR. Following the procedure, participants completed a survey based on their comfort and satisfaction.

Participants/materials, setting, methods

Inclusion criteria included single blastocyst transfer and a normal uterine cavity. Participants were recruited and randomized on the day of ET. Those allocated to the CTT group, had their embryo transferred without ultrasound, depositing the embryo 6cm from the external os. Those in the 4DUS group had their ET using transvaginal 4D ultrasonography and had their embryos deposited at the maximal implantation point (MIP).

Main results and the role of chance

Results were available from a total of 295 women (8% attrition rate, CTT n = 153; 4DUS n = 142)).

No demographic differences between the two groups (CTT and 4DUS) were noted including age (p = 0.05), BMI (p = 0.29), duration of infertility (p = 0.94), type of infertility (p = 0.68) or embryo quality (p = 0.89). All the 4DUS and 95% of the CTT group were performed by the same practitioner.

The 4DUS resulted in significantly higher CPR (50% vs 36% p = 0.015, OR 1.78 (1.12-2.84)) and LBR (41%vs 28%, p = 0.021, OR 1.77 (1.09-2.87)).

There were no statistically significant differences between miscarriage (p = 0.494), pregnancy of unknown location (p = 0.141) or ectopic pregnancy rates (p = 0.958) between the two groups. The 4DUS process took significantly longer time compared with the CTT procedure (15.7 vs 10.2 minutes respectively, p &lt; 0.01). The results of the survey showed no statistical difference between patient comfort (p = 0.17) or satisfaction (p = 0.08) between the groups however there were significantly more positive comments in the 4DUS (p &lt; 0.01). In the 4DUS group there was no difference in mean endometrial thickness (P = 0.186) or endometrial volume (p = 0.836) between pregnant and non-pregnant patients.

Limitations, reasons for caution

Due to the nature of this trial we were unable to blind the participants due to the obvious differences between the methods. Wallace catheters were used for the CTT and Kitazato catheters for the 4DUS, whilst a methodological weakness; previous meta-analysis has not shown any difference between different soft catheters.

Wider implications of the findings

LBRs, when utilizing 4DUS, are significantly higher than the current UK average (41%vs22-23%) and significantly higher than CTT. 4DUS allows for superior imaging of the uterine cavity, tailoring the embryo deposition point specifically to the patient. Further RCTs are required to confirm that 4DUS is the superior technique for ET.

Measurement of the Charge-Averaged Elastic Lepton-Proton Scattering Cross Section by the OLYMPUS Experiment

We report the first measurement of the average of the electron-proton and positron-proton elastic scattering cross sections. This lepton charge-averaged cross section is insensitive to the leading effects of hard two-photon exchange, giving more robust access to the proton's electromagnetic form factors. The cross section was extracted from data taken by the OLYMPUS experiment at DESY, in which alternating stored electron and positron beams were scattered from a windowless gaseous hydrogen target. Elastic scattering events were identified from the coincident detection of the scattered lepton and recoil proton in a large-acceptance toroidal spectrometer. The luminosity was determined from the rates of Møller, Bhabha, and elastic scattering in forward electromagnetic calorimeters. The data provide some selectivity between existing form factor global fits and will provide valuable constraints to future fits.

Prevalence of home parenteral nutrition in children

BACKGROUND

Use of HPN in paediatrics in the UK has increased rapidly over the last 20 years but the prevalence of HPN has been challenging to define. Clinicians in the UK have noted an evolving complexity of cases and perceive improved outcomes and increased acceptability of long-term PN. These factors combined have the potential to increase the burden on existing paediatric gastroenterology services in the UK.

METHODS

A national database was interrogated to define the prevalence of HPN in children in the UK and to explore outcomes for patients receiving HPN.

RESULTS

Since 2015, 525 children were notified to the database; of these patients, mortality was <5% and intestinal transplant occurred in 1%. In 2019, 389 children received HPN in the UK; this is nearly double the number last reported in 2012 and is a prevalence of 30 per million children. Short bowel syndrome is the largest category of these patients. However, a poorly defined group including those with multisystem disease has increased 10 fold since 2012 and is now the second largest category.

CONCLUSIONS

Long term HPN in childhood is safe and associated with good survival and low risk of the need for intestinal transplantation.

Maternal Outcomes of Ongoing Pregnancies Complicated by Fetal Life-Limiting Conditions

OBJECTIVE

This study aimed to examine maternal outcomes of ongoing pregnancies complicated by fetal life-limiting conditions.

STUDY DESIGN

This was a retrospective matched cohort study of women with a diagnosis of fetal life-limiting condition between 2010 and 2018 in a single academic center. Cases were matched to controls (women who had normal fetal anatomic survey) according to year of delivery, body mass index, and parity in a 1:4 ratio. Bivariable and multivariable analyses were performed to compare the prevalence of the primary composite outcome, which included any one of the following: preeclampsia, gestational diabetes, cesarean delivery, third and fourth degree laceration, postpartum hemorrhage, blood transfusion, endometritis or wound infection, maternal intensive care unit admission, hysterectomy and maternal death, between cases and controls.

RESULTS

During the study period, we found 101 cases that met inclusion criteria, matched to 404 controls. The rate of the composite maternal outcome did not differ between the two groups (39.6 vs. 38.9%, p = 0.948). For individual outcomes, women with diagnosis of fetal life-limiting condition had higher rates of blood transfusion (2.0 vs. 0%, p = 0.005) and longer length of the first stage of labor (median of 12 [6.8-22.0] hours vs. 6.6 [3.9-11.0] hours; p < 0.001). In a multivariable analysis, first stage of labor continued to be longer by an average of 6.48 hours among women with a diagnosis of fetal life-limiting condition compared with controls.

CONCLUSION

After controlling for confounding factors, except a longer first stage of labor, women diagnosed with fetal life-limiting conditions who continued the pregnancy did not have a higher rate of adverse maternal outcomes.

KEY POINTS

· The rates of ongoing pregnancies with fetal life-limiting conditions are increasing.. · Women with ongoing pregnancies with fetal life-limiting conditions had longer first stage of labor.. · The rest of the adverse maternal outcomes were not increased in this obstetric population..

Occupational therapy, loneliness and social isolation: a thematic review of the literature

Background/Aims

Loneliness and social isolation are thought to have a negative impact on health and wellbeing. There is little literature that provides an explicit focus on loneliness and social isolation in occupational therapy practice. The aim of this study was to explore themes related to loneliness and social isolation in occupational therapy-related literature and consider the implications for practice.

Methods

CINAHL, Medline, Pub Med, AMed, PsycINFO, TRIP Database, and Science direct and Web of science databases were used to identify articles pertaining to occupational therapy, loneliness and social isolation.

Results

A total of 20 articles were included and three themes were identified: loneliness and social isolation are detrimental to health and wellbeing; factors associated with increased loneliness and social isolation; factors that protect against the impact of loneliness and social isolation.

Conclusions

Loneliness and social isolation have a significant impact on the health and wellbeing of the people occupational therapists work with. Occupational therapy practice should include the recognition and assessment of loneliness and social isolation, and interventions to help reduce any impacts on health and wellbeing.

An investigation of the effects of walking frame height and width on walking stability

BACKGROUND

Walking aids are designed for structural support during walking, however, surprisingly self-reported use of a walking aid ("Yes, I use one.") has been identified as a risk factor for falling. Adjustment and design of walking aids may affect their usefulness in facilitating a stable walking pattern. We previously identified that increased body weight transfer onto a walking frame ('device loading') is associated with increased user stability.

RESEARCH QUESTION

We asked: "Could adjustment of walking frame height to a lower height than clinically recommended serve as a mechanism to facilitate device loading and thereby increase stability? And: "Do ultra-narrow frames have an adverse effect on stability as compared to standard-width frames?

METHODS

Ten older adults that were users of front-wheeled walking frames walked with walking frames of 1) 'standard width, standard height', 2)'standard width, low height', 3)'narrow width, standard height'. Smart Walker technology was used to record forces acting on the walking frame and inside the user's shoes, and cameras recorded relative position of the user's feet in relation to the frame's feet. Stability of the user-frame system and device loading (percent body weight transferred onto the frame) were calculated. A general linear mixed effects model was used for statistical analysis.

RESULTS

A lower height setting did not increase device loading and stability, therefore adjusting the height to a lower setting proved to be an unsuccessful mechanism to increase stability. However, device loading was positively correlated with stability for all frame conditions (p < 0.05). Finally, stability was reduced when walking with the ultra-narrow, as compared to standard-width, frame (p = 0.002).

SIGNIFICANCE

To increase stability in fall-prone users, active encouragement to transfer body weight onto the walking frame is needed. Considering the adverse effects of ultra-narrow frames on stability, such frames should be prescribed and used with caution.

Final results for the neutron -asymmetry parameter A0 from the UCNA experiment

The UCNA experiment was designed to measure the neutron β-asymmetry parameter A0 using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium were polarized via transport through a 7 T magnetic field, and then directed to a 1 T solenoidal electron spectrometer, where the decay electrons were detected in electron detector packages located on the two ends of the spectrometer. A value for A0 was then extracted from the asymmetry in the numbers of counts in the two detector packages. We summarize all of the results from the UCNA experiment, obtained during run periods in 2007, 2008–2009, 2010, and 2011–2013, which ultimately culminated in a 0.67% precision result for A0.

Cligosiban, A Novel Brain-Penetrant, Selective Oxytocin Receptor Antagonist, Inhibits Ejaculatory Physiology in Rodents

INTRODUCTION

Few treatments are available for men with premature ejaculation (PE); oxytocin (OT) receptor antagonism in the central nervous system (CNS) is a potential new approach.

AIM

To determine if cligosiban selectively inhibits human OT receptors, penetrates the CNS, shows pharmacology in the CNS, and effects ejaculatory physiology in pre-clinical systems.

METHODS

Experiments complied with United Kingdom legislation and were subject to local ethical review. In vitro potency and selectivity of cligosiban was assessed using recombinant and native OT receptor systems including both neuronal and non-neuronal cell types. Selectivity was determined over neighboring V_1A, V_1B, and V₂ vasopressin receptors using a combination of recombinant and native vasopressin receptor assay systems. To determine an effect on central OT receptors and on ejaculation, cligosiban was evaluated in 2 anesthetized rat models-the electromyography model of ejaculatory physiology and a model of OT-mediated CNS neuronal firing. The CNS penetration of cligosiban was also determined by measuring cerebrospinal fluid and plasma drug concentrations following an intravenous (IV) infusion in rats.

MAIN OUTCOME MEASURE

These were functional measures of pharmacology in vitro, in cell lines and tissues, and in vivo in rats.

RESULTS

Cligosiban is a potent OT receptor antagonist, with a base dissociation constant of 5.7 nmol/L against native human uterine smooth muscle cell OT receptors. Cligosiban displays similar antagonistic potency against human recombinant and rat native OT receptors, including neuronal OT receptors. Cligosiban demonstrates >100-fold selectivity over human V_1A, V_1B, and V₂ vasopressin receptors. In the electromyography model, cligosiban (0.9 mg/kg, IV bolus) reduced the bulbospongiosum burst pattern and contraction amplitude associated with ejaculation. In the anesthetized CNS neuronal firing model, the same dosing regimen of cligosiban (0.9 mg/kg IV bolus) modulated the OT-mediated response in the nucleus tractus solitarius. After systemic dosing to rats, cligosiban showed good CNS penetration.

CLINICAL IMPLICATIONS

As the first highly selective and centrally penetrant OT receptor antagonist, cligosiban represents a promising compound to test the clinical hypothesis that antagonism of central OT receptors may be of therapeutic benefit in the treatment of PE.

STRENGTH & LIMITATIONS

The pharmacology and selectivity of cligosiban is determined using functional assays in recombinant cell lines, native cell lines, and tissue. Functional outcomes in in vivo systems are linked to CNS measures of pharmacology. The translation of the animal models of ejaculation to PE in man is unproven.

CONCLUSION

Cligosiban, a potent, selective OT receptor antagonist, demonstrated CNS penetration and pharmacology and, using the same dosing regimen, inhibited apomorphine-induced ejaculation in rats. Cligosiban is a promising compound to test the clinical hypothesis that antagonism of central OT receptors may be of therapeutic benefit in the treatment of PE. Wayman C, Russell R, Tang K, et al.

Progesterone Application to the Rat Forehead Produces Corneal Antinociception

Purpose

Ocular pain and discomfort are the most defining symptoms of dry eye disease. We determined the ability of topical progesterone to affect corneal sensitivity and brainstem processing of nociceptive inputs.

Methods

Progesterone or vehicle gel was applied to the shaved forehead in male Sprague Dawley rats. As a site control, gel also was applied to the cheek on the side contralateral to corneal stimulation. Corneal mechanical thresholds were determined using the Cochet-Bonnet esthesiometer in intact and lacrimal gland excision–induced dry eye animals. Eye wipe behaviors in response to hypertonic saline and capsaicin were examined, and corneal mustard oil-induced c-Fos immunohistochemistry was quantified in the brainstem spinal trigeminal nucleus.

Results

Progesterone gel application to the forehead, but not the contralateral cheek, increased corneal mechanical thresholds in intact and lacrimal gland excision animals beginning <30 minutes after treatment. Subcutaneous injection of the local anesthetic bupivacaine into the forehead region before application of progesterone prevented the increase in corneal mechanical thresholds. Furthermore, progesterone decreased capsaicin-evoked eye wipe behavior in intact animals and hypertonic saline evoked eye wipe behavior in dry eye animals. The number of Fos-positive neurons located in the caudal region of the spinal trigeminal nucleus after corneal mustard oil application was reduced in progesterone-treated animals.

Conclusions

Results from this study indicate that progesterone, when applied to the forehead, produces analgesia as indicated by increased corneal mechanical thresholds and decreased nociceptive responses to hypertonic saline and capsaicin.

Osteoarthritis in England: Incidence Trends From National Health Service Hospital Episode Statistics

Objective

It is typical in epidemiological research of osteoarthritis (OA) to collect data for the hand, hip, and knee. However, little population‐based data exist for this disease in the foot. Thus, we addressed patterns of OA for the foot compared with the hand, hip, and knee spanning 2000/2001 to 2017/2018 in England.

Methods

Secondary‐care data from 3 143 928 patients with OA of the foot, hand, hip, and knee were derived from the National Health Service (NHS) Hospital Episode Statistics (HES) database. Distribution, population prevalence, and incidence of joint‐specific OA were stratified by age and sex.

Results

OA incidence increased significantly at the foot [3.8% (95% confidence interval [CI] 3.0, 4.6)], hand [10.9% (10.1, 11.7)], hip [3.8% (2.9, 4.7)], and knee [2.9% (2.2, 3.6)] per year from 2000/2001 to 2017/2018. A higher proportion of women were diagnosed with OA, whereas greater incidence in men was estimated for the hand and hip. Foot OA presented comparable diagnosis numbers to the hand. More recently during 2012/2013 to 2017/2018, a significant rise in hip OA was estimated among younger adults, whereas knee OA decreased across all age groups. Incidence of OA in the foot and hand were particularly significant among the 75 or older age group, though bimodal age distributions were observed for both sites.

Conclusion

The significant increase in secondary care records for OA in England underscores the importance of exploring possible causative factors and identifying groups most at risk. Further detailed data may be particularly important for the hip, which represents significant incidence among younger adults. Greater incidence of OA in the foot compared with the knee emphasizes the need for well‐conducted epidemiological research in this area. Monitoring the performance of surgical outcomes at the population‐level for this frequently affected yet understudied site could have substantial potential to reduce the socioeconomic burden it represents to the NHS.

Treatment of obstetric post-dural puncture headache. Part 2: epidural blood patch

The 2009-12 MBRRACE-UK report highlighted the deaths of two women in whom dural puncture had occurred during insertion of a labour epidural catheter. Despite suffering long-term headaches, neither woman was adequately followed-up after discharge from hospital. Death resulted from a cerebral vein thrombosis in one case and a subdural haematoma in the other. Due to significant variation in the treatment of obstetric post-dural puncture headache, an Obstetric Anaesthetists' Association working group was set up to produce evidence-based guidelines to guide clinicians. These guidelines have been condensed into two review articles. In this second review, the role of an epidural blood patch is discussed using a question and answer format.

Learning from the transfer of a fellowship programme to support primary care workforce needs in the UK: a qualitative study

OBJECTIVES

Service redesign, including workforce development, is being championed by UK health service policy. It is allowing new opportunities to enhance the roles of staff and encourage multiprofessional portfolio working. New models of working are emerging, but there has been little research into how innovative programmes are transferred to and taken up by different areas. This study investigates the transferability of a 1-year post-Certification of Completion of Training fellowship in urgent and acute care from a pilot in the West Midlands region of England to London and the South East.

DESIGN

A qualitative study using semistructured interviews supplemented by observational data of fellows' clinical and academic activities. Data were analysed using a thematic framework approach.

SETTING AND PARTICIPANTS

Two cohorts of fellows (15 in total) along with key stakeholders, mentors, tutors and host organisations in London and the South East (LaSE). Fellows had placements in primary and secondary care settings (general practice, emergency department, ambulatory care, urgent care and rapid response teams), together with academic training.

RESULTS

Seventy-six interviews were completed with 50 participants, with observations in eight clinical placements and two academic sessions. The overall structure of the West Midlands programme was retained and the core learning outcomes adopted in LaSE. Three fundamental adaptations were evident: broadening the programme to include multiprofessional fellows, changes to the funding model and the impact that had on clinical placements. These were felt to be key to its adoption and longer-term sustainability.

CONCLUSION

The evaluation demonstrates a model of training that is adaptable and transferable between National Health Service regions, taking account of changing national and regional circumstances, and has the potential to be rolled out widely.

Influence of Community-Level Cultural Beliefs about Autism on Families' and Professionals' Care for Children

This qualitative study aimed to understand how community-level cultural beliefs affect families' and professionals' care for children with autism and developmental delays in immigrant communities, as a first step towards promoting early identification and access to early intervention services. The study was part of the larger New York City (NYC) Korean Community Autism Project, which was designed to identify strategies to increase awareness of autism and reduce delays in treatment seeking within the NYC Korean-American community. Our study elicited early childcare workers' and church leaders' beliefs about autism and developmental disorders and, in particular, early intervention. We also elicited responses to newly developed outreach materials targeting this community. An inductive approach was used to identify concepts and categories associated with autism. Our study confirmed that discomfort, stigma and discrimination are the prevailing community attitudes toward autism and developmental disorders in the Korean-American community. Families' and professionals' understanding of autism and their care for children are affected by these community beliefs. Approaching immigrant communities with general information about child development and education rather than directly talking about autism and developmental disorders is likely to engage more families and professionals in need for diagnostic evaluation and early intervention for autism.

Associations between genomic stratification of breast cancer and centrally reviewed tumour pathology in the METABRIC cohort

The integration of genomic and transcriptomic profiles of 2000 breast tumours from the METABRIC [Molecular Taxonomy of Breast Cancer International Consortium] cohort revealed ten subtypes, termed integrative clusters (IntClust/s), characterised by distinct genomic drivers. Central histopathology (N = 1643) review was undertaken to explore the relationship between these ten molecular subtypes and traditional clinicopathological features. IntClust subtypes were significantly associated with histological type, tumour grade, receptor status, and lymphocytic infiltration (p < 0.0001). Lymph node status and Nottingham Prognostic Index [NPI] categories were also significantly associated with IntClust subtype. IntClust 3 was enriched for tubular and lobular carcinomas, the latter largely accounting for the association with CDH1 mutations in this cluster. Mucinous carcinomas were not present in IntClusts 5 or 10, but did not show an association with any of the remaining IntClusts. In contrast, medullary-like cancers were associated with IntClust 10 (15/26). Hormone receptor-positive tumours were scattered across all IntClusts. IntClust 5 was dominated by HER2 positivity (127/151), including both hormone receptor-positive (60/72) and hormone receptor-negative tumours (67/77). Triple-negative tumours comprised the majority of IntClust 10 (132/159) and around a quarter of IntClust 4 (52/217). Whilst the ten IntClust subtypes of breast cancer show characteristic patterns of association with traditional clinicopathological variables, no IntClust can be adequately identified by these variables alone. Hence, the addition of genomic stratification has the potential to enhance the biological relevance of the current clinical evaluation and facilitate genome-guided therapeutic strategies.

Factors influencing career intentions on completion of general practice vocational training in England: a cross-sectional study

OBJECTIVES

General practice is experiencing a growing crisis with the numbers of doctors who are training and then entering the profession in the UK failing to keep pace with workforce needs. This study investigated the immediate to medium term career intentions of those who are about to become general practitioners (GPs) and the factors that are influencing career plans.

DESIGN

Online questionnaire survey, with quantitative answers analysed using descriptive statistics and free text data analysed using a thematic framework approach.

SETTING AND PARTICIPANTS

Doctors approaching the end of 3-year GP vocational training in the West Midlands, England.

RESULTS

178 (57.2%) doctors completed the survey. Most participants planned to work as salaried GPs or locums rather than entering a general practice partnership for at least the first 5 years post-completion of training; others failed to express a career plan or planned to leave general practice completely or work overseas. Many were interested in developing portfolio careers.The quality of general practice experience across undergraduate, foundation and vocational training were reported as influencing personal career plans, and in particular perceptions about workload pressure and morale within the training practices in which they had been placed. Experience of a poor work-life balance as a trainee had a negative effect on career intentions, as did negative perceptions about how general practice is portrayed by politicians and the media.

CONCLUSION

This study describes a number of potentially modifiable factors related to training programmes that are detrimentally influencing the career plans of newly trained GPs. In addition, there are sociodemographic factors, such as age, gender and having children, which are also influencing career plans and so need to be accommodated. With ever-increasing workload in general practice, there is an urgent need to understand and where possible address these issues at national and local level.

Challenges of modern day transition care in inflammatory bowel disease: From inflammatory bowel disease to biosimilars

In this article we discuss the challenges of delivering a high quality Transition care. A good understanding of the adolescent needs with good communication between Transition care physicians and the patient is essential for good continuity of care. Despite availability of several guidelines, one model doesn’t fit all and any transition service development should be determined by the local need and available healthcare facilities.
