Navigating a maze: Midwives' identity response to the enactment of an abortion law in Chile.

BACKGROUND: Chilean midwives have been identified as essential for successfully implementing an abortion law, a practice which could potentially be understood as contradicting their central mission. Nevertheless, to date, there has been no investigation into how Chilean midwives have incorporated induced abortion care provision into their professional identity. OBJECTIVE: To elucidate how Chilean midwives understand and provide abortion care and how they have (re)defined their professional identity to include induced abortion care. This article reports the findings of the second part of this aim. METHODS: This study was underpinned by a constructivist grounded theory methodology informed by a reproductive justice and feminist perspective. Midwives from Chile who have cared for women undergoing abortion were invited to participate in the study. After purposive and theoretical sampling, fifteen midwives were recruited. FINDINGS: Midwives' identity is woman-centred, with high value placed on their role protecting life. These two aspects of midwives' identity are in contradiction when providing abortion care. Midwives' identity results from and informs midwives' practice. Midwifery regulation influences both practice and identity. The model 'Navigating a maze' explains the interaction of these three elements. CONCLUSION: Midwives' identity response to the enactment of the Chilean abortion law is an example of how professional identity must navigate regulation and practice to make sense of its purpose. In light of this study's findings, the current tension experienced in midwives' identity should be carefully attended to prevent adverse outcomes for midwives and the Chilean population.

Chilean midwives' experiences while providing induced abortion care after the enactment of a law decriminalising abortion.

INTRODUCTION: The recent change in Chilean legislation towards abortion enabled midwives to include the care of women having an induced abortion within their scope of practice. However, midwives' identity could be strained by induced abortion care provision as it is contrary to midwives' traditional role. Considering this, the aim of the study was to elucidate how Chilean midwives understand and provide abortion care. METHODS: A constructivist grounded theory study was conducted using online semi-structured in-depth interviews. Midwives were purposively sampled considering maximum variation criteria and then theoretical sampling occurred. Saturation was achieved with fifteen interviews. Interviews were conducted in Spanish and then translated into English. Constant comparison analysis generated categories. Data were managed using NVivo 12. All interviewees provided their consent to be part of this study. RESULTS: This article reports on the experiences of nine midwives who had provided lawful induced abortion care in Chile. The experiences of these midwives were grouped into two major categories: 'Defining a position towards abortion' and 'Abortion care is emotional labour'. CONCLUSION: Midwives can successfully provide abortion care despite being challenged by certain areas of it. Considering the high demand for emotional labour in abortion care, efforts should be made to increase midwives' emotional self-regulation skills. Likewise, organisations should strengthen and implement their offer of well-being and emotional self-care support to midwives.

Addressing cancer anorexia-cachexia in older patients: Potential therapeutic strategies and molecular pathways.

Cancer cachexia (CC) syndrome, a feature of cancer-associated muscle wasting, is particularly pronounced in older patients, and is characterised by decreased energy intake and upregulated skeletal muscle catabolic pathways. To address CC, appetite stimulants, anabolic drugs, cytokine mediators, essential amino acid supplementation, nutritional counselling, cognitive behavioural therapy, and enteral nutrition have been utilised. However, pharmacological treatments that have also shown promising results, such as megestrol acetate, anamorelin, thalidomide, and delta-9-tetrahydrocannabinol, have been associated with gastrointestinal and cardiovascular complications. Emerging evidence on the efficacy of probiotics in modulating gut microbiota also presents a promising adjunct to traditional therapies, potentially enhancing nutritional absorption and systemic inflammation control. Additionally, low-dose olanzapine has demonstrated improved appetite and weight management in older patients undergoing chemotherapy, offering a potential refinement to current therapeutic approaches. This review aims to elucidate the molecular mechanisms underpinning CC, with a particular focus on the role of anorexia in exacerbating muscle wasting, and to propose pharmacological and non-pharmacological strategies to mitigate this syndrome, particularly emphasising the needs of an older demographic. Future research targeting CC should focus on refining appetite-stimulating drugs with fewer side-effects, specifically catering to the needs of older patients, and investigating nutritional factors that can either enhance appetite or minimise suppression of appetite in individuals with CC, especially within this vulnerable group.

A comparison of bolus track and test bolus computed tomography pulmonary angiography and the implications on pulmonary and aortic vessel enhancement, effective dose and suboptimal scan rate.

INTRODUCTION: Bolus track and test bolus are the most commonly used contrast timing protocols to undertake computed tomography pulmonary angiography (CTPA). The aim of this study was to compare test bolus and bolus track contrast enhancement protocols in terms of enhancement of the pulmonary vessels and aorta, radiation dose and suboptimal scan rate to determine the optimal technique for CTPA. METHODS: A total of 200 CTPA examinations (100 using each protocol) performed between January and February 2021 were assessed retrospectively. All scans were performed on a 2x128 Dual Source Siemens Drive Scanner. CT attenuation was measured in Hounsfield Units (HU), with measurements taken from the main pulmonary trunk, right pulmonary artery and left pulmonary artery, ascending and descending aorta. The mean effective dose was calculated from the dose-length product (DLP). The suboptimal scan rate was calculated as the percentage of examinations below 210HU. RESULTS: The average HU of the pulmonary arteries was 358 HU ± SD 129.2 in the test bolus group and increased to 394 HU ± SD 133.9 in the bolus track group with a P value of ≤0.05. The average HU of the aorta was 235 HU ± SD 82.8 in the test bolus group and increased to 319 HU ± SD 91.8 in the bolus track group with a P value of <0.001. Although not statistically significant, the mean effective dose was reduced by 4.2% for the bolus track protocol (2.4 mSv vs. 2.5 mSv, P > 0.05). Fewer suboptimal scans were performed with the bolus track protocol (5 scans <210HU Bolus Track vs. 9 scans <210HU Test Bolus). CONCLUSION: The bolus track protocol results in increased enhancement of the pulmonary arteries and aorta, with the added benefits of a lower suboptimal scan rate and lower effective dose.

'A good decision is the one that feels right for me': Codesign with patients to inform theoretical underpinning of a decision aid website.

INTRODUCTION: Patient decision aids (PtDA) complement shared decision-making with healthcare professionals and improve decision quality. However, PtDA often lack theoretical underpinning. We are codesigning a PtDA to help people with increased genetic cancer risks manage choices. The aim of an innovative workshop described here was to engage with the people who will use the PtDA regarding the theoretical underpinning and logic model outlining our hypothesis of how the PtDA would lead to more informed decision-making. METHODS: Short presentations about psychological and behavioural theories by an expert were interspersed with facilitated, small-group discussions led by patients. Patients were asked what is important to them when they make health decisions, what theoretical constructs are most meaningful and how this should be applied to codesign of a PtDA. An artist created a visual summary. Notes from patient discussions and the artwork were analysed using reflexive thematic analysis. RESULTS: The overarching theme was: It's personal. Contextual factors important for decision-making were varied and changed over time. There was no one 'best fit' theory to target support needs in a PtDA, suggesting an inductive, flexible framework approach to programme theory would be most effective. The PtDA logic model was revised based on patient feedback. CONCLUSION: Meaningful codesign of PtDA including discussions about the theoretical mechanisms through which they support decision-making has the potential to lead to improved patient care through understanding the intricately personal nature of health decisions, and tailoring content and format for holistic care. PATIENT CONTRIBUTION: Patients with lived experience were involved in codesign and coproduction of this workshop and analysis as partners and coauthors. Patient discussions were the primary data source. Facilitators provided a semi-structured guide, but they did not influence the patient discussions or provide clinical advice. The premise of this workshop was to prioritise the importance of patient lived experience: to listen, learn, then reflect together to understand and propose ideas to improve patient care through codesign of a PtDA.

UK national trainee survey of hepatology training, research and the future workforce.

Objective: The increasing prevalence of liver disease in the UK means there is a pressing need to expand the hepatology workforce. This survey aims to evaluate current hepatology training provision, and trainee attitudes towards future careers in hepatology. Method: An electronic survey was distributed to higher specialty gastroenterology and hepatology trainees in the UK between March and May 2022. Results: 138 trainees completed the survey covering all training grades and regions of the UK. 73.7% reported receiving adequate hepatology training currently, with 55.6% intending to become future hepatologists. Trainee preference for future hepatology consultant posts in specialist liver centres were almost threefold higher compared with district general hospitals (60.9% vs 22.6%). All trainees, irrespective of training grade reported high confidence in managing decompensated cirrhosis in both inpatient and outpatient settings. Senior trainees (grade ST6 and higher), without advanced training programme (ATP) experience reported significantly lower confidence in managing viral hepatitis, hepatocellular carcinoma and post-transplant patients compared with equivalent trainees with ATP experience. For junior trainees (IMT3-ST5), remaining in their current deanery was the most important factor when considering future hepatology training application. Conclusions: There is a significant need to deliver widely available training on the management of complex liver disease to improve non-ATP trainee confidence. Innovative job planning strategies are required to encourage trainees to pursue careers outside of specialist liver centres. Expansion of hepatology training networks with wider geographical coverage are needed to address the growing need for more hepatologists around the UK.

Exploring sonographer emotional well-being: NHS sonographers' experience of the restorative function of professional supervision.

Introduction: Following recommendations of the Francis report (2013), healthcare professional groups have formalised restorative supervision within practice in order to maintain emotional well-being among staff and provide quality of care for patients. There is a scarcity of research available on how professional supervision is utilised as a restorative device within current practice for sonographers. Methodology: An online cross-sectional, descriptive survey was used to gain qualitative details and nominal data on sonographer experiences of professional supervision. Themes were developed through thematic analysis. Results: A total of 56% of participants did not identify professional supervision as part of their current practice; 50% of participants felt emotionally unsupported within their work. The majority felt 'unsure' of how professional supervision would affect their working day; however, they highlighted that a restorative function would be valued equally as professional development functions of practice. The barriers to professional supervision as a restorative function demonstrate that an understanding of what sonographer needs are should be considered in approaches to professional supervision. Conclusion: This study found that participants identify professional supervision in its formative and normative functions more commonly than its restorative functions. It also found that sonographers are found wanting of emotional support, with 50% of sonographers feeling unsupported and identifying a restorative supervision need to their working practice. Implications for practice: The need to establish a system that supports the emotional well-being of sonographers is highlighted. This should help with retention of sonographers in a career where burnout is evidenced.

Impact of BCR::ABL1 transcript type on RT-qPCR amplification performance and molecular response to therapy.

Several studies have reported that chronic myeloid leukaemia (CML) patients expressing e14a2 BCR::ABL1 have a faster molecular response to therapy compared to patients expressing e13a2. To explore the reason for this difference we undertook a detailed technical comparison of the commonly used Europe Against Cancer (EAC) BCR::ABL1 reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) assay in European Treatment and Outcome Study (EUTOS) reference laboratories (n = 10). We found the amplification ratio of the e13a2 amplicon was 38% greater than e14a2 (p = 0.015), and the amplification efficiency was 2% greater (P = 0.17). This subtle difference led to measurable transcript-type dependent variation in estimates of residual disease which could be corrected by (i) taking the qPCR amplification efficiency into account, (ii) using alternative RT-qPCR approaches or (iii) droplet digital PCR (ddPCR), a technique which is relatively insensitive to differences in amplification kinetics. In CML patients, higher levels of BCR::ABL1/GUSB were identified at diagnosis for patients expressing e13a2 (n = 67) compared to e14a2 (n = 78) when analysed by RT-qPCR (P = 0.0005) but not ddPCR (P = 0.5). These data indicate that widely used RT-qPCR assays result in subtly different estimates of disease depending on BCR::ABL1 transcript type; these differences are small but may need to be considered for optimal patient management.

The high-volume haemodiafiltration vs high-flux haemodialysis registry trial (H4RT): a multi-centre, unblinded, randomised, parallel-group, superiority study to compare the effectiveness and cost-effectiveness of high-volume haemodiafiltration and high-flux haemodialysis in people with kidney failure on maintenance dialysis using linkage to routine healthcare databases for outcomes.

BACKGROUND: More than a third of the 65,000 people living with kidney failure in the UK attend a dialysis unit 2-5 times a week to have their blood cleaned for 3-5 h. In haemodialysis (HD), toxins are removed by diffusion, which can be enhanced using a high-flux dialyser. This can be augmented with convection, as occurs in haemodiafiltration (HDF), and improved outcomes have been reported in people who are able to achieve high volumes of convection. This study compares the clinical- and cost-effectiveness of high-volume HDF compared with high-flux HD in the treatment of kidney failure. METHODS: This is a UK-based, multi-centre, non-blinded randomised controlled trial. Adult patients already receiving HD or HDF will be randomised 1:1 to high-volume HDF (aiming for 21+ L of substitution fluid adjusted for body surface area) or high-flux HD. Exclusion criteria include lack of capacity to consent, life expectancy less than 3 months, on HD/HDF for less than 4 weeks, planned living kidney donor transplant or home dialysis scheduled within 3 months, prior intolerance of HDF and not suitable for high-volume HDF for other clinical reasons. The primary outcome is a composite of non-cancer mortality or hospital admission with a cardiovascular event or infection during follow-up (minimum 32 months, maximum 91 months) determined from routine data. Secondary outcomes include all-cause mortality, cardiovascular- and infection-related morbidity and mortality, health-related quality of life, cost-effectiveness and environmental impact. Baseline data will be collected by research personnel on-site. Follow-up data will be collected by linkage to routine healthcare databases - Hospital Episode Statistics, Civil Registration, Public Health England and the UK Renal Registry (UKRR) in England, and equivalent databases in Scotland and Wales, as necessary - and centrally administered patient-completed questionnaires. In addition, research personnel on-site will monitor for adverse events and collect data on adherence to the protocol (monthly during recruitment and quarterly during follow-up). DISCUSSION: This study will provide evidence of the effectiveness and cost-effectiveness of HD as compared to HDF for adults with kidney failure in-centre HD or HDF. It will inform management for this patient group in the UK and internationally. TRIAL REGISTRATION: ISRCTN10997319 . Registered on 10 October 2017.

Standardization of molecular monitoring of CML: results and recommendations from the European treatment and outcome study.

Standardized monitoring of BCR::ABL1 mRNA levels is essential for the management of chronic myeloid leukemia (CML) patients. From 2016 to 2021 the European Treatment and Outcome Study for CML (EUTOS) explored the use of secondary, lyophilized cell-based BCR::ABL1 reference panels traceable to the World Health Organization primary reference material to standardize and validate local laboratory tests. Panels were used to assign and validate conversion factors (CFs) to the International Scale and assess the ability of laboratories to assess deep molecular response (DMR). The study also explored aspects of internal quality control. The percentage of EUTOS reference laboratories (n = 50) with CFs validated as optimal or satisfactory increased from 67.5% to 97.6% and 36.4% to 91.7% for ABL1 and GUSB, respectively, during the study period and 98% of laboratories were able to detect MR4.5 in most samples. Laboratories with unvalidated CFs had a higher coefficient of variation for BCR::ABL1IS and some laboratories had a limit of blank greater than zero which could affect the accurate reporting of DMR. Our study indicates that secondary reference panels can be used effectively to obtain and validate CFs in a manner equivalent to sample exchange and can also be used to monitor additional aspects of quality assurance.

Experiences of midwives and nurses when implementing abortion policies: A systematic integrative review.

INTRODUCTION: Policy implementation can be affected by what individuals believe to be right and wrong. When implementing abortion policies, providers' moral beliefs can be relevant in the success of the implementation process. Considering that midwives and nurses are direct providers of abortion care, exploring their experiences related to abortion policy implementation could provide helpful information to prevent policy failure. METHODS: Systematic integrative review. The studies were identified through an electronic search strategy and the screening of the reference lists of all selected articles. Studies were retrieved from eight medical and social sciences databases. Thirty-one studies focused on midwives' and nurses' experiences of implementing abortion policies, irrespective of setting or age of study were included in this review. Studies included used qualitative, quantitative and mixed methods. Study quality was appraised using the Mixed Method Appraisal Tool version 2018. No study was excluded from this review based on its quality appraisal. RESULTS: In terms of their quality, most studies included in this review were conducted appropriately. Three superordinate themes represent the main elements that challenge midwives and nurses when providing abortion care. The first superordinate theme identified that many midwives and nurses believed fetuses are sentient beings, making them worthy of compassionate treatment. The next superordinate theme was focused on preferences and expectations about abortion care. Finally, the third superordinate theme illustrates midwives' and nurses' experiences with other team members, highlights their creativity when challenged with insufficient resources and provides a glimpse of the numerous techniques used for coping with work-related stress. CONCLUSION: Midwives and nurses worldwide face multiple challenges when providing abortion care. Guidelines aiming to support policy implementation should consider how abortion affects healthcare providers and suggest appropriate measures to reduce these and other barriers. Midwives and nurses technical and ethical competencies for abortion provision should be strengthened.

Veterans with Traumatic Brain Injury-related Ocular Injury and Vision Dysfunction: Recommendations for Rehabilitation.

SIGNIFICANCE: We know the prevalence of traumatic brain injury (TBI)-related vision impairment and ocular injury symptoms. Lacking is an understanding of health care utilization to treat these symptoms. Utilization knowledge is important to structuring access to treatment, identifying clinical training needs, and providing evidence of the effectiveness of treatment. PURPOSE: This article reports rehabilitation, glasses/contacts, and imaging/photography/video recommendations made by optometrists and ophthalmologists as part of the Department of Veterans Affairs-mandated Performance of Traumatic Brain Injury Specific Ocular Health and Visual Functioning Examination administered to veterans with TBI at Department of Veterans Affairs polytrauma specialty facilities. METHODS: Using a retrospective design, natural language processing, and descriptive and regression statistics, data were analyzed for 2458 Operation Enduring Freedom/Operation Iraqi Freedom veterans who were administered the mandated examination between 2008 and 2017. RESULTS: Of the 2458 veterans, vision rehabilitation was recommended for 24%, glasses/contacts were recommended for 57%, and further imaging/photography/video testing was recommended for 58%. Using key words in the referral, we determined that 37% of veterans were referred to blind rehabilitation, 16% to occupational therapy, and 3% to low-vision clinics. More than 50% of the referrals could have been treated by blind rehabilitation, occupational therapy, or low-vision clinics. Rehabilitation referrals were significantly associated with younger age, floaters, photosensitivity, double vision, visual field and balance deficits, dizziness, and difficulty reading. In comparison, prescriptions for glasses and contacts were associated with older age, photosensitivity, blurred vision, decreased visual field and night vision, difficulty reading, and dry eye. Imaging/photography/video testing was associated with floaters, photosensitivity, and headache. CONCLUSIONS: Findings delineate service delivery models available to veterans with TBI-related vision impairment. The challenge these data address is the lack of clear paths from diagnosis of TBI to identification of vision dysfunction deficits to specialized vision rehabilitation, and finally to community reintegration and community based-vision rehabilitation.

A prognostic model, including quantitative fetal fibronectin, to predict preterm labour: the QUIDS meta-analysis and prospective cohort study.

BACKGROUND: The diagnosis of preterm labour is challenging. False-positive diagnoses are common and result in unnecessary, potentially harmful treatments (e.g. tocolytics, antenatal corticosteroids and magnesium sulphate) and costly hospital admissions. Measurement of fetal fibronectin in vaginal fluid is a biochemical test that can indicate impending preterm birth. OBJECTIVES: To develop an externally validated prognostic model using quantitative fetal fibronectin concentration, in combination with clinical risk factors, for the prediction of spontaneous preterm birth and to assess its cost-effectiveness. DESIGN: The study comprised (1) a qualitative study to establish the decisional needs of pregnant women and their caregivers, (2) an individual participant data meta-analysis of existing studies to develop a prognostic model for spontaneous preterm birth within 7 days in women with symptoms of preterm labour based on quantitative fetal fibronectin and clinical risk factors, (3) external validation of the prognostic model in a prospective cohort study across 26 UK centres, (4) a model-based economic evaluation comparing the prognostic model with qualitative fetal fibronectin, and quantitative fetal fibronectin with cervical length measurement, in terms of cost per QALY gained and (5) a qualitative assessment of the acceptability of quantitative fetal fibronectin. DATA SOURCES/SETTING: The model was developed using data from five European prospective cohort studies of quantitative fetal fibronectin. The UK prospective cohort study was carried out across 26 UK centres. PARTICIPANTS: Pregnant women at 22+0-34+6 weeks' gestation with signs and symptoms of preterm labour. HEALTH TECHNOLOGY BEING ASSESSED: Quantitative fetal fibronectin. MAIN OUTCOME MEASURES: Spontaneous preterm birth within 7 days. RESULTS: The individual participant data meta-analysis included 1783 women and 139 events of spontaneous preterm birth within 7 days (event rate 7.8%). The prognostic model that was developed included quantitative fetal fibronectin, smoking, ethnicity, nulliparity and multiple pregnancy. The model was externally validated in a cohort of 2837 women, with 83 events of spontaneous preterm birth within 7 days (event rate 2.93%), an area under the curve of 0.89 (95% confidence interval 0.84 to 0.93), a calibration slope of 1.22 and a Nagelkerke R2 of 0.34. The economic analysis found that the prognostic model was cost-effective compared with using qualitative fetal fibronectin at a threshold for hospital admission and treatment of ≥ 2% risk of preterm birth within 7 days. LIMITATIONS: The outcome proportion (spontaneous preterm birth within 7 days of test) was 2.9% in the validation study. This is in line with other studies, but having slightly fewer than 100 events is a limitation in model validation. CONCLUSIONS: A prognostic model that included quantitative fetal fibronectin and clinical risk factors showed excellent performance in the prediction of spontaneous preterm birth within 7 days of test, was cost-effective and can be used to inform a decision support tool to help guide management decisions for women with threatened preterm labour. FUTURE WORK: The prognostic model will be embedded in electronic maternity records and a mobile telephone application, enabling ongoing data collection for further refinement and validation of the model. STUDY REGISTRATION: This study is registered as PROSPERO CRD42015027590 and Current Controlled Trials ISRCTN41598423.

Identifying which women with symptoms of labour will give birth early is challenging, so many women unnecessarily receive therapies aimed at preventing complications in preterm birth. A test called quantitative fetal fibronectin, which uses vaginal swab samples, may help to improve the diagnosis of preterm labour. Fetal fibronectin is a protein that is released from the fetal membranes that surround the developing baby in the womb. The lower the concentration of fetal fibronectin, the less likely the occurrence of preterm birth. Our aim was to see if quantitative fetal fibronectin, in combination with some features of pregnancy (e.g. previous pregnancy history and twin pregnancy), can accurately predict preterm birth in women who have symptoms of preterm labour. We asked women, their partners, doctors and midwives what information would be most useful to them, and how this should be presented. We then analysed previous research data; we used quantitative fetal fibronectin and clinical risk factors together to predict the chance of preterm birth. We explored which features could predict preterm birth most effectively while still being good value to the NHS. To ensure that this risk predictor worked in UK populations, we undertook a research study across 26 UK hospitals. Women who had symptoms of preterm labour were invited to participate. We collected information from these women (approximately 3000 women), including quantitative fetal fibronectin results. We found that a risk predictor comprising quantitative fetal fibronectin and four other features performed best at predicting whether or not preterm birth will occur within the next week for women with symptoms of preterm labour, and that this had potential to be clinically useful and cost-effective. The quantitative fetal fibronectin testing process was acceptable to women, and clinicians found the risk predictor useful. We used our findings to develop a risk calculator to help women and clinicians assess how likely preterm birth is, and decide whether or not to start treatment.

Nutritional status and intake in patients with non-cystic fibrosis bronchiectasis (NCFB) - a cross sectional study.

BACKGROUND & AIMS: Bronchiectasis is a heterogeneous, chronic respiratory condition, in which the role of nutrition remains unclear and nutritional guidance is lacking. Few studies have explored the role of nutrition in disease management, and little is known about nutritional requirements during periods of stability or metabolic stress. The aim of this study was to characterise nutritional status and intakes in a cohort of patients and identify potential associations with body composition and functional capacity. METHODS: A prospective observational cohort study was undertaken in an adult population (>17 years). Bronchiectasis was confirmed by high-resolution computerised tomography (HRCT). Anthropometric (weight, height, Body Mass Index (BMI), triceps skinfold thickness (TSF), mid upper-arm circumference (MUAC) and mid arm muscle circumference (MAMC)] lung function and nutritional intakes were measured. Results were analysed as a whole and by disease aetiology [primary ciliary dyskinesia (PCD), Idiopathic cause (IC), bronchiectasis in association with asthma and other] and associations tested. RESULTS: In total, 128 participants (65.5% female) completed the study. Median handgrip strength (HGS) in the total sample was only 66.5% (IQR 60.5-89.8) of reference population norms and was low for those with PCD [58.0% (IQR 43.5-70.0))]. Univariate regression indicated that BMI was a statistically significant predictor of lung function in the whole population with HGS and weight identified as statistically significant predictors of lung function in PCD. The total population and each sub-group failed to meet estimated average requirements for energy but exceeded the Reference nutrient intake (RNI) for protein. Vitamin D was consistently <35% of the RNI. CONCLUSION: BMI lay within normal to overweight ranges within the whole population and sub-groups, but masked important functional, body composition and nutritional deficits. This was particularly so within a younger sub-group with PCD, who had impaired muscle function, when compared to other causal and associative diseases.

Development and validation of a risk prediction model of preterm birth for women with preterm labour symptoms (the QUIDS study): A prospective cohort study and individual participant data meta-analysis.

BACKGROUND: Timely interventions in women presenting with preterm labour can substantially improve health outcomes for preterm babies. However, establishing such a diagnosis is very challenging, as signs and symptoms of preterm labour are common and can be nonspecific. We aimed to develop and externally validate a risk prediction model using concentration of vaginal fluid fetal fibronectin (quantitative fFN), in combination with clinical risk factors, for the prediction of spontaneous preterm birth and assessed its cost-effectiveness. METHODS AND FINDINGS: Pregnant women included in the analyses were 22+0 to 34+6 weeks gestation with signs and symptoms of preterm labour. The primary outcome was spontaneous preterm birth within 7 days of quantitative fFN test. The risk prediction model was developed and internally validated in an individual participant data (IPD) meta-analysis of 5 European prospective cohort studies (2009 to 2016; 1,783 women; mean age 29.7 years; median BMI 24.8 kg/m2; 67.6% White; 11.7% smokers; 51.8% nulliparous; 10.4% with multiple pregnancy; 139 [7.8%] with spontaneous preterm birth within 7 days). The model was then externally validated in a prospective cohort study in 26 United Kingdom centres (2016 to 2018; 2,924 women; mean age 28.2 years; median BMI 25.4 kg/m2; 88.2% White; 21% smokers; 35.2% nulliparous; 3.5% with multiple pregnancy; 85 [2.9%] with spontaneous preterm birth within 7 days). The developed risk prediction model for spontaneous preterm birth within 7 days included quantitative fFN, current smoking, not White ethnicity, nulliparity, and multiple pregnancy. After internal validation, the optimism adjusted area under the curve was 0.89 (95% CI 0.86 to 0.92), and the optimism adjusted Nagelkerke R2 was 35% (95% CI 33% to 37%). On external validation in the prospective UK cohort population, the area under the curve was 0.89 (95% CI 0.84 to 0.94), and Nagelkerke R2 of 36% (95% CI: 34% to 38%). Recalibration of the model's intercept was required to ensure overall calibration-in-the-large. A calibration curve suggested close agreement between predicted and observed risks in the range of predictions 0% to 10%, but some miscalibration (underprediction) at higher risks (slope 1.24 (95% CI 1.23 to 1.26)). Despite any miscalibration, the net benefit of the model was higher than "treat all" or "treat none" strategies for thresholds up to about 15% risk. The economic analysis found the prognostic model was cost effective, compared to using qualitative fFN, at a threshold for hospital admission and treatment of ≥2% risk of preterm birth within 7 days. Study limitations include the limited number of participants who are not White and levels of missing data for certain variables in the development dataset. CONCLUSIONS: In this study, we found that a risk prediction model including vaginal fFN concentration and clinical risk factors showed promising performance in the prediction of spontaneous preterm birth within 7 days of test and has potential to inform management decisions for women with threatened preterm labour. Further evaluation of the risk prediction model in clinical practice is required to determine whether the risk prediction model improves clinical outcomes if used in practice. TRIAL REGISTRATION: The study was approved by the West of Scotland Research Ethics Committee (16/WS/0068). The study was registered with ISRCTN Registry (ISRCTN 41598423) and NIHR Portfolio (CPMS: 31277).

Exploring the STEP-uP to practice: A survey of UK Lead Midwives for Education views of the STudent midwife Extended Practice Placement during the first wave of the COVID-19 pandemic.

OBJECTIVE: to assess the effect of implementation of the extended placement option available to midwifery students during the first wave of the COVID-19 pandemic. DESIGN: Online survey open from 2nd June 2020 to 15th July 2020. SETTING: United Kingdom. PARTICIPANTS: Lead Midwives for Education (LMEs). FINDINGS: A total of 38 of 55 LMEs responded (response rate 69%). The majority of Approved Education Institutions (AEIs) offered an extended placement to students, but with some variation in the choices offered, unrelated to geographical location or size of student cohort. AEIs appeared to provide the majority of decisional support for students. Many practice learning environments became unavailable, particularly community, gynaecology/medical wards and neonatal units. LMEs experienced both internal and external pressures to instigate rapid change. KEY CONCLUSIONS: The impact of COVID-19 on midwifery education is significant and will need continual scrutiny to minimise future detriment. The pressures of providing midwifery education throughout the early phase of COVID-19 were substantial, but it is important that we learn from the immediate changes made, value and pursue the changes that have been beneficial, and learn from those that were not. IMPLICATIONS FOR PRACTICE/RESEARCH: Student learning experiences have undergone significant change during the pandemic. It is essential to assess what effect the extended placement has had on student readiness for practice, their confidence, resilience, mental health, and attrition and retention. Educators transitioned to remote working, and rapidly assimilated new skills for online education; exploration of the impact of this is recommended.

A retrospective cohort study of nutritional status, nutritional interventions and hospital admissions in patients with chronic pancreatitis managed at a tertiary referral centre.

PURPOSE: Chronic pancreatitis (CP) is a complex disease process causing abdominal pain, diarrhoea and weight loss. The long-term nutritional implications however are not well documented. The aim of this study was to evaluate nutritional status in patients with CP over an extended time period and assess frequency and duration of CP related hospitalisation. METHODS: Retrospective analysis of patients with known CP for nutritional status (weight, BMI, and weight changes), nutritional interventions and hospital admissions were recorded. Weight was recorded at 3 points; baseline consultation, first review and most recent consultations. Number of dietitian contacts and documented evidence of nutritional advice/interventions were recorded and grouped. Nutritional status was compared in those who had dietetic input with those who did not. RESULTS: 46 consecutive subjects (34/46 male, mean age 56.15 years, 26/46 alcohol aetiology) were followed up for a mean of 5.24 years. 38/46 lost weight from baseline to review with mean percentage weight change: baseline to review = -7.36, p < 0.0001, baseline to recent = -6.70, p = 0.003, review to recent = 1.47, p = 0.581. 23/46 were reviewed by dietitian (mean 4.65 reviews). The number of dietitian reviews were positively associated with weight gain; baseline to recent (p = 0.010) and review to recent (p = 0.011). 23/46 received nutritional advice/interventions with 11 requiring enteral feeding. 29/46 experienced unplanned CP related hospital admissions (median 3) comprising 30 median total admission days. CONCLUSION: Patients with CP lose a significant amount of weight in a short time period which plateaus. Dietitian review is associated with improved nutritional status in CP.

Promises and challenges of adoptive T-cell therapies for solid tumours.

Cancer is a leading cause of death worldwide and, despite new targeted therapies and immunotherapies, many patients with advanced-stage- or high-risk cancers still die, owing to metastatic disease. Adoptive T-cell therapy, involving the autologous or allogeneic transplant of tumour-infiltrating lymphocytes or genetically modified T cells expressing novel T-cell receptors or chimeric antigen receptors, has shown promise in the treatment of cancer patients, leading to durable responses and, in some cases, cure. Technological advances in genomics, computational biology, immunology and cell manufacturing have brought the aspiration of individualised therapies for cancer patients closer to reality. This new era of cell-based individualised therapeutics challenges the traditional standards of therapeutic interventions and provides opportunities for a paradigm shift in our approach to cancer therapy. Invited speakers at a 2020 symposium discussed three areas-cancer genomics, cancer immunology and cell-therapy manufacturing-that are essential to the effective translation of T-cell therapies in the treatment of solid malignancies. Key advances have been made in understanding genetic intratumour heterogeneity, and strategies to accurately identify neoantigens, overcome T-cell exhaustion and circumvent tumour immunosuppression after cell-therapy infusion are being developed. Advances are being made in cell-manufacturing approaches that have the potential to establish cell-therapies as credible therapeutic options. T-cell therapies face many challenges but hold great promise for improving clinical outcomes for patients with solid tumours.
