The mental health and well-being implications of a mesothelioma diagnosis: A mixed methods study

PURPOSE

Mesothelioma is an incurable, asbestos-related cancer with a poor prognosis. There is scant evidence about the mental health and well-being impacts on patients and carers living with the illness. This study aimed to investigate mesothelioma's impact on mental health and well-being and the scale of mental health conditions in patients and informal carers.

METHODS

A mixed-methods design was used: a cross-sectional survey of mesothelioma patients and informal carers plus semi-structured interviews with patients and carers. The survey used validated scales collecting data on mental health aspects of mesothelioma: the EQ5D to assess health-related quality-of-life; the Hospital Anxiety and Depression scale; the PCL-5 to assess Posttraumatic Stress; and the Posttraumatic Growth Inventory. The datasets were integrated during analysis.

RESULTS

96 useable survey responses were received. A clinical level of depression was reported by 29 participants (30.21%), of anxiety by 48 (50%), of posttraumatic distress disorder by 32 (33.33%), and of posttraumatic growth by 34 (35.42%). Carers had worse scores than patients. Three main themes were developed from interviews with 10 patients and 11 carers: 'Prognosis', 'Support from services', and 'Social connections and communication'.

CONCLUSIONS

Healthcare professionals delivering a mesothelioma diagnosis require regular training in communication skills plus updating in current treatment options, so they provide an appropriate mix of realism and hope. Better signposting to mental health support is needed for patients and carers. Our introduction of posttraumatic growth into the mesothelioma literature is novel. We recommend specialist nurses are trained to recognise, understand, and foster posttraumatic growth.

'Moving on' for Adults With a Learning Disability and Their Families: A Constructivist Grounded Theory Study

Ending familial co-residence, termed 'moving on' by participants, is an increasingly relevant life transition for people with a learning disability due to increasing life expectancy and policy developments. Nevertheless, there is an absence of research exploring this transition experience in a United Kingdom (UK) context. This constructivist grounded theory study therefore aimed to explore, conceptualise, and theorise the 'moving on' experiences of adults with a learning disability and their families. This article reports the experiences of five adults with a learning disability and nine family members in England, UK. Narrative interviews and creative storybook methods were used to collect data between April 2015 and May 2016. Constant comparative methods, theoretical sampling, and memo writing were used throughout data collection and analysis. Participants with a learning disability presented personal growth and greater life fulfilment over the course of the transition; they flourished. In parallel, family members relinquished their care responsibilities. Importantly, the iterative and reciprocal relationship between flourishing and relinquishing shows that ongoing family member involvement is crucial during and following relocation. Family members identified factors that potentially inhibit relinquishing: pressure to 'let go', different perceptions of independence between family members and service providers, inadequate future investment, and rapport with professional carers. These novel insights led to the generation of the first known mid-range theory concerning this transition, entitled 'Moving on: flourishing and relinquishing'. Findings will guide future research in this field and facilitate the design of appropriate support for people with a learning disability and their families.

Development of the nursing associate professional identity: A longitudinal qualitative study

AIM

The aim of this study was to understand the factors that contribute to the development of the nursing associate professional identity.

DESIGN

A 3-year longitudinal qualitative study of trainee nursing associates.

METHODS

Trainee nursing associates in England were interviewed remotely annually in February 2020, March 2021 and March 2022. They also provided diary entries. Data were anonymised, transcribed and analysed thematically.

RESULTS

Nursing associate professional identity was developed through: increased knowledge, skills and responsibility; and self-perceptions of identity alongside responses to the role by colleagues. Tensions arose when the scope of practice expected by organisations differed from that expected by the nursing associates. Frustrations occurred when nursing associates were perceived as substitutes for Registered Nurses in the context of nursing workforce shortages.

CONCLUSION

Nursing associates in this study clearly valued their new knowledge, skills and responsibility, enabling them to provide enhanced patient care. Increased clarity of role boundaries is necessary in enhancing the professional identity of nursing associates and reducing inter-professional tensions arising from role ambiguity within health and social care organisations.

IMPLICATIONS FOR THE PROFESSION

National guidance and employers should provide clarity on the boundaries of the nursing associate role which will strengthen their professional identity and mitigate role ambiguity within health and social care organisations.

REPORTING METHOD

The Consolidated Criteria for Reporting Qualitative Research has been used to guide reporting.

PATIENT OF PUBLIC CONTRIBUTION

A patient and public involvement group was consulted during the initial study design stage.

IMPACT

This study aimed to understand the factors which contribute to the development of a nursing associate professional identity. Nursing associate professional identity is developed through increased knowledge, skills and responsibility, and the perceptions of identity by participants themselves and their colleagues. The findings should inform the implementation of initiatives to clarify nursing associate role boundaries and the development of similar roles internationally.

A systematic review and meta-analysis of the clinimetric properties of the core outcome measurement instruments for clinical effectiveness trials of nutritional and metabolic interventions in critical illness (CONCISE)

BACKGROUND

CONCISE is an internationally agreed minimum set of outcomes for use in nutritional and metabolic clinical research in critically ill adults. Clinicians and researchers need to be aware of the clinimetric properties of these instruments and understand any limitations to ensure valid and reliable research. This systematic review and meta-analysis were undertaken to evaluate the clinimetric properties of the measurement instruments identified in CONCISE.

METHODS

Four electronic databases were searched from inception to December 2022 (MEDLINE via Ovid, EMBASE via Ovid, CINAHL via Healthcare Databases Advanced Search, CENTRAL via Cochrane). Studies were included if they examined at least one clinimetric property of a CONCISE measurement instrument or recognised variation in adults ≥ 18 years with critical illness or recovering from critical illness in any language. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist for systematic reviews of Patient-Reported Outcome Measures was used. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used in line with COSMIN guidance. The COSMIN checklist was used to evaluate the risk of bias and the quality of clinimetric properties. Overall certainty of the evidence was rated using a modified Grading of Recommendations, Assessment, Development and Evaluation approach. Narrative synthesis was performed and where possible, meta-analysis was conducted.

RESULTS

A total of 4316 studies were screened. Forty-seven were included in the review, reporting data for 12308 participants. The Short Form-36 Questionnaire (Physical Component Score and Physical Functioning), sit-to-stand test, 6-m walk test and Barthel Index had the strongest clinimetric properties and certainty of evidence. The Short Physical Performance Battery, Katz Index and handgrip strength had less favourable results. There was limited data for Lawson Instrumental Activities of Daily Living and the Global Leadership Initiative on Malnutrition criteria. The risk of bias ranged from inadequate to very good. The certainty of the evidence ranged from very low to high.

CONCLUSIONS

Variable evidence exists to support the clinimetric properties of the CONCISE measurement instruments. We suggest using this review alongside CONCISE to guide outcome selection for future trials of nutrition and metabolic interventions in critical illness.

Single Institute Experience Treating Uterine Carcinosarcoma: Outcome Analysis

PURPOSE/OBJECTIVE(S)

Uterine carcinosarcoma (UCS) is rare with a poor prognosis. We report over 10 years' experience, reporting prognostic and predictive factors for overall survival (OS) and disease-free survival (DFS).

MATERIALS/METHODS

Patient, tumor, treatment and relapse characteristics of 168 women with stages I-IVB UCS treated at our institute between 2010 and 2020 were analyzed. OS and DFS at 2 and 5 years were the primary outcomes, estimated with Kaplan-Meier. The benefit of adjuvant chemotherapy and radiotherapy in the curative cohort was estimated using the log rank test.

RESULTS

Median follow up was 23 months (range 1-137 months). 34% had FIGO stage IA disease, 10% IB, 8% II. 16% IIIA-IIIC1, and 10% IIIC2 and 22% IVB. The overall 2-year OS was 52% and 5-year OS 30%. 2-year OS by FIGO stage were: IA 66%; IB 63%; II 54%; IIIA-IIIC1 54%; IIIC2 45%; IVB 26%. Within the curative cohort who were surgically staged, 2-year DFS was 47% and 5-year was 30%. 2-year DFS were 61% in IA disease, 53% IB, 12% II, 51% IIIA-IIIC1, and 45% IIIC2 and 4% IVB. A greater risk of death was conferred by lack of adjuvant treatment (lack of chemo > lack of radiotherapy). The most common chemotherapy regimen used was Carboplatin Paclitaxel and pelvic radiotherapy 45Gy 25F over 5 weeks. The combination of surgery and chemotherapy +/- radiotherapy significantly improved OS compared to surgery +/- radiotherapy (HR 0.5 with CI 0.3 - 0.9) p<0.05. Radiotherapy improved OS compared to surgery only (HR 0.4 with CI 0.2 - 1.1) p<0.05. Relapse rate in all patients following curative treatment is 72% within year 1 and 86% within year 2 from diagnosis. In 52 patients with stage 1A disease treated with surgery +/- radiotherapy only, 42.4% relapsed, median time to relapse was 8 months from diagnosis. Relapse occurred despite 69.2 % stage 1A patients receiving adjuvant pelvic EBRT and in these patients relapse within the pelvis occurred in 50%.

CONCLUSION

This study constitutes the largest retrospective analyses of long-term mortality outcomes in UCS and confirms poor outcomes despite curative surgery and adjuvant therapy. Most patients relapse within the first year following curative treatment. The use of adjuvant chemotherapy improves OS in all stages. In stage 1A disease 42 % patients relapse locally and distantly. This is an area of controversy and this data would strongly suggest that the addition of adjuvant paclitaxel-carboplatin or cisplatin-doxorubicin chemotherapy to EBRT should be considered in all patients including earliest stage disease.

Single Institute Experience with MRI-Guided Adaptive Brachytherapy for Locally Advanced Cervix Cancer: Long Term Outcomes and Toxicity Analysis

PURPOSE/OBJECTIVE(S)

We report over 10 years' experience of MRI-guided adaptive brachytherapy (MRIGABT) in locally advanced cervix cancer (LACC).

MATERIALS/METHODS

A total of 162 patients with LACC FIGO stage IB-IVB were treated at our institute between 2010 and 2020. Treatment consisted of chemoradiotherapy (weekly intravenous cisplatin 40 mg/m², 5 cycles, 1 day per cycle, 45-50.4 Gy external beam radiotherapy (EBRT) in 1·8-2 Gy fractions, followed by MRIGABT. Target volume definition and dose reporting for MRIGABT was according to GEC-ESTRO recommendations. MRIGABT dose prescription was according to our institutional practice. Overall survival (OS) and disease-free survival (DFS) were the primary endpoints. Kaplan-Meier estimates were calculated for OS and DFS at 2, 5 and 10-years. Organ-specific late toxicity grade ≥3 (≥G3) (CTCAEv5.0) was reported, alongside rates of bowel fistula, stricture, and perforation. Using logistic regression, we explored the relationship between EQD2 D2cc bladder and ≥G3 genitourinary (GU) toxicity. We compared patient proportions developing ≥ G3 GU toxicity in those who received EQD2 ≥85 Gy versus <85 Gy. We examined the following predictors of ≥G3 gastrointestinal (GI) toxicity: EQD2 dose (≥65 Gy versus <65 Gy), pre-existing bowel conditions, nodal boost, and extended field EBRT.

RESULTS

Median follow up was 4.7 years (IQR 3.3-7.1 years). Median EBRT dose was 50.4 Gy (IQR 50.4-50.4 Gy); 91% received chemotherapy. Median high-risk clinical target volume (HRCTV) was 23.6 cm3 (IQR 16.6-31.3 cm3). Median doses were as follows; D90 HRCTV 88.9 Gy EQD210 (IQR 84.1-91.3 Gy), median D2cc bladder 81.6 (IQR 76.9-85.7 Gy), rectum 62.2 (IQR 57.9-65.3 Gy), sigmoid 67.4 (IQR 60.8-71.1 Gy), and bowel 55 (IQR 49.9-63.2 Gy), (all EQD23). The 2, 5 and-10-year OS were 98%, 80% and 75%. The 2, 5 and 10-year DFS were 98%, 75% and 60%. Late toxicity ≥G3 was 9% GU, 6% GI and 3% vaginal. There was a significant relationship between EQD2 and ≥G3 GU toxicity (OR: 1.11, 95% CI: 1.01-1.25; P = 0.04). When comparing those who received EQD2≥ 85Gy versus <85Gy, higher doses were associated with a greater proportion of ≥G3 GU toxicity (13% vs 6%). No significant predictors of ≥ G3 GI toxicity were observed.

CONCLUSION

We observed excellent LC and OS. A significant relationship was found between EQD2 >85 Gy and bladder toxicity, although ≥G3 toxicity was low. We did not identify predictors of bowel toxicity. New predictors of bowel toxicity are required. Mean EBRT dose, D1.0 cc rectum, sigmoid and bowel are being investigated further.

Training and development experiences of nursing associate trainees based in primary care across England: a qualitative study

BACKGROUND

The nursing associate role was first deployed in England in 2019 to fill a perceived skills gap in the nursing workforce between healthcare assistants and registered nurses and to offer an alternative route into registered nursing. Initially, trainee nursing associates were predominantly based in hospital settings; however, more recently, there has been an increase in trainees based in primary care settings. Early research has focussed on experiences of the role across a range of settings, particularly secondary care; therefore, little is known about the experiences and unique support needs of trainees based in primary care.

AIM

To explore the experiences and career development opportunities for trainee nursing associates based in primary care.

METHODS

This study used a qualitative exploratory design. Semi-structured interviews were undertaken with 11 trainee nursing associates based in primary care from across England. Data were collected between October and November 2021, transcribed and analysed thematically.

FINDINGS

Four key themes relating to primary care trainee experiences of training and development were identified. Firstly, nursing associate training provided a 'valuable opportunity for career progression'. Trainees were frustrated by the 'emphasis on secondary care' in both academic content and placement portfolio requirements. They also experienced 'inconsistency in support' from their managers and assessors and noted a number of 'constraints to their learning opportunities', including the opportunity to progress to become registered nurses.

CONCLUSION

This study raises important issues for trainee nursing associates, which may influence the recruitment and retention of the nursing associate workforce in primary care. Educators should consider adjustments to how the curriculum is delivered, including primary care skills and relevant assessments. Employers need to recognise the resource requirements for the programme, in relation to time and support, to avoid undue stress for trainees. Protected learning time should enable trainees to meet the required proficiencies.

Mesothelioma patient and carer experience research: A research prioritisation exercise

OBJECTIVES

Incidence of mesothelioma worldwide is growing and the UK reports the highest global incidence. Mesothelioma is an incurable cancer with a high symptom burden. However, it is under researched when compared to other cancers. The aim of this exercise was to identify unanswered questions about the mesothelioma patient and carer experience in the UK and to prioritise research areas of most importance through consultation with patients, carers and professionals.

MATERIALS AND METHODS

A virtual Research Prioritisation Exercise was conducted. This involved a review of mesothelioma patient and carer experience literature to identify research gaps and a national online survey to identify and rank research gaps. Following this, a modified consensus method with mesothelioma experts (patients, carers and professionals from healthcare, legal, academic and volunteer organisations) was undertaken to reach a consensus regarding mesothelioma patient and carer experience research priorities.

RESULTS

Survey responses were received from 150 patients, carers and professionals and 29 research priorities were identified. During consensus meetings, 16 experts refined these into a list of 11 key priorities. The five most urgent priorities were symptom management, receiving a mesothelioma diagnosis, palliative and end of life care, treatment experiences, barriers and facilitators to joined up service provision.

CONCLUSION

This novel priority setting exercise will shape the national research agenda, contribute knowledge to inform nursing and wider clinical practice and ultimately improve the experiences of mesothelioma patients and carers.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Consequences of understaffing on type of missed community care- a cross-sectional study

BACKGROUND

Resource cuts to primary and community care in combination with a decline of those working in community settings is compromising quality of care and patient safety in the UK. It is reported that the negative consequences of understaffing and underfunding have worsened due to the COVID-19 pandemic.

OBJECTIVE

This is a cross-sectional study that aimed to examine short and long-term District and Community nursing working conditions. The objectives were to assess the prevalence of understaffing and missed care and the relationship between individual and organisational factors and their association with missed care outcome. We further explored the relationship between additional caseload, staffing levels and missed care.

METHODS

We developed a questionnaire based on the validated MISSCARE survey. Outcome measures were, number of vacancies per team, staffing levels, reported incidence of missed care, type of missed care, length of shift and overtime.

RESULTS

Only 23% of teams reported having no vacancies. The mean staffing ratio was reported at 60%, including agency/bank staff (0.59±1.5). Prevalence of missed care was relatively high (60%≈). The distribution of types of missed care was spread evenly across all types of nursing care. A backward stepwise regression analysis showed that the Proportion of Permanent staff capacity OR=7.9 (95% CI 0.09-0.65), Active Caseload Size OR= 5.5 (95% CI: 1.0 - 1.003), Number of RNs on the team (OR 4.8 (95% CI:1.003-1.058) and Amount of Overtime worked (OR= 3.9 (95% CI:0.98-1.0) variable are statistically significant predictors of missed care. The analysis showed an increase in additional allocated cases per RN as the permanent staff proportion decreased to 70%, at which point the likelihood of reported Missed Care outcome peaks.

CONCLUSION

The compromised quality of care related to human resources and organisational aspects of the nursing process. Where RNs worked longer hours to make up for the backlog of cases, the prevalence of missed care was more likely. Longer working hours in the community increased the risk of compromised care and sub-optimal patient care. The aspects of the nursing process identified as 'missed' related to The World Health Organisation's three main pillars of community nursing (health promotion, patient education and screening). As such, significant components of the two first pillars are, according to these data, being undermined.

Impact of Covid-19 on lung cancer and Mesothelioma specialist nurses: A survey of experiences and perceptions

Purpose

The covid-19 global pandemic has impacted on nurses who have rapidly adapted to new ways of working, and experienced negative impacts due to over-stretched services. Two surveys captured the experiences of lung cancer and mesothelioma specialist nurses in the United Kingdom (UK) in 2020, but the impact of later stages of the pandemic was unknown. This study aimed to explore the impact of covid-19 on lung Cancer and mesothelioma nurses since January 2021, the second wave of the pandemic.

Methods

An online cross-sectional survey with both open and closed questions explored the impact of covid-19 on ways of working and workload, quality of care, and health and wellbeing. The survey was open to UK based lung cancer and mesothelioma advanced or specialist nurses.

Results

85 nurses responded to the survey. The majority were Clinical Nurse Specialists, based in England. Respondents reported changes in ways of working due to redeployment, staff shortages, and home working. Widespread adoption of virtual working practices led to concerns of negative impacts. Perceived excessive workload impacted on care with two-thirds of the sample (57, 67%) reporting they had been unable to provide the same quality of care to patients. Impacts on nurses’ health and wellbeing were reported with two-thirds of the sample (56, 66%) reporting a deterioration in emotional wellbeing and mental health. Coping mechanisms employed included online team support to share experiences and increased uptake of exercise; however, impacts on lifestyle and access to coping mechanisms varied.

Conclusion

Nurses have stepped up to the challenges of the pandemic with teamwork and innovation, but pressure arising from the pandemic and high workloads led to negative impacts on wellbeing. The authors have provided recommendations to improve patient care and support the wellbeing of nurses, which will be key to a resilient workforce living with covid-19. Whilst this study focussed on lung cancer and mesothelioma specialists, the findings have wider implications for other cancer specialties.

Moral distress in advanced practice nurses during the COVID-19 pandemic

BACKGROUND

Moral distress arises when a person is aware of the right course to take but is prevented from acting on it by institutional constraints. While this concept has been considered by nursing ethicists for many years, it has been particularly associated with the unprecedented healthcare conditions caused by the coronavirus disease 2019 (COVID-19) pandemic.

AIM

To investigate the level of moral distress affecting advanced practice nurses (APNs) in the UK during the COVID-19 pandemic.

METHOD

This was a mixed-methods study in which a bespoke cross-sectional survey was sent to 243 APNs from across the UK who had been recruited to a broader longitudinal cohort study. The survey asked about their experiences, well-being and moral distress. Open-ended questions asked about their concerns regarding the health and well-being of their patients and colleagues.

FINDINGS

A total of 97 APNs completed the survey, yielding a 40% response rate. Levels of moral distress were significantly higher among APNs working in secondary care (P=0.026) compared with those working in primary care. All of the respondents expressed concerns about patients due to delayed care and about the mental well-being of their colleagues, particularly those who were redeployed to COVID-19 wards.

CONCLUSION

The COVID-19 pandemic has caused moral and psychological distress for APNs. However, the type of distress and its direct causes varied among these practitioners. Tailored support is required to address moral distress and subsequently improve staff retention.

Core outcome measures for clinical effectiveness trials of nutritional and metabolic interventions in critical illness: an international modified Delphi consensus study evaluation (CONCISE)

Background

Clinical research on nutritional and metabolic interventions in critically ill patients is heterogenous regarding time points, outcomes and measurement instruments used, impeding intervention development and data syntheses, and ultimately worsening clinical outcomes. We aimed to identify and develop a set of core outcome domains and associated measurement instruments to include in all research in critically ill patients.

Methods

An updated systematic review informed a two-stage modified Delphi consensus process (domains followed by instruments). Measurement instruments for domains considered ‘essential’ were taken through the second stage of the Delphi and a subsequent consensus meeting.

Results

In total, 213 participants (41 patients/caregivers, 50 clinical researchers and 122 healthcare professionals) from 24 countries contributed. Consensus was reached on time points (30 and 90 days post-randomisation). Three domains were considered ‘essential’ at 30 days (survival, physical function and Infection) and five at 90 days (survival, physical function, activities of daily living, nutritional status and muscle/nerve function). Core ‘essential’ measurement instruments reached consensus for survival and activities of daily living, and ‘recommended’ measurement instruments for physical function, nutritional status and muscle/nerve function. No consensus was reached for a measurement instrument for Infection. Four further domains met criteria for ‘recommended,’ but not ‘essential,’ to measure at 30 days post-randomisation (organ dysfunction, muscle/nerve function, nutritional status and wound healing) and three at 90 days (frailty, body composition and organ dysfunction).

Conclusion

The CONCISE core outcome set is an internationally agreed minimum set of outcomes for use at 30 and 90 days post-randomisation, in nutritional and metabolic clinical research in critically ill adults.

More vaquita porpoises survive than expected

In 2018, it was estimated that fewer than 20 of Mexico’s endemic vaquita porpoise Phocoena sinus remained, and the species was declining by 47% yr-1. Entanglement in gillnets is the sole threat to the species, and since the last population size estimate, gillnetting has increased in the small area where most vaquitas remain—a 12 × 24 km area in the Gulf of California near San Felipe, Mexico. We conducted research efforts in 2019 and 2021 in that area to estimate the minimum numbers of adults and calves and look for any signs that vaquitas are unhealthy. Through expert elicitation, we estimated between 7 and 15 unique individuals were seen in 2019 and 5-13 were seen in 2021. Calves were seen in both years, and all vaquitas appeared healthy. Population projections from the last full survey indicated that more vaquitas have survived than expected. We suggest that these surviving adult vaquitas may have learned to avoid entanglement in gillnets. These vaquitas and their calves provide hope that the species can survive. However, given the high levels of illegal gillnetting and the theft of equipment which hindered our monitoring efforts, and with only around 10 individuals remaining, survival can only be assured if vaquita habitat is made gillnet-free.

A tale of two bridges: Factors influencing career choices of trainee nursing associates in England: A longitudinal qualitative study

AIM

The nursing associate role has created a new second-level nursing role and provided an alternative route into registered nursing. For some, this provides a previously inaccessible opportunity for career progression. The aim of the study was to understand the factors that influence career choices of trainee nursing associates.

DESIGN

A longitudinal qualitative study of trainee nursing associate motivations, experiences and career aspirations.

METHODS

Semi-structured interviews with trainee nursing associates from across England, UK, in February 2020 (N = 14) and March 2021 (N = 13). Diary data were also collected. Interview and diary data were analysed thematically. Reporting has followed COREQ guidelines.

RESULTS

Nursing associate training was viewed by some as a bridge into registered nursing. Role ambiguity led several to seek perceived security offered by the Registered Nurse profession. Those preferring to remain as nursing associates were keen to embed the bridging role between healthcare assistants and Registered Nurses, valuing a positive workplace culture.

Patients' and informal carers' experience of living with mesothelioma: A systematic rapid review and synthesis of the literature

PURPOSE

Mesothelioma is a rare and incurable cancer linked to asbestos exposure. It primarily affects the pleura. This systematic rapid review aimed to identify what is known about the experience of living with mesothelioma, from the perspective of patients and their informal carers.

METHODS

Medline, PsycInfo, Scopus and the Cumulative Index to Nursing and Allied Health Literature were searched for empirical studies published between December 2008 and October 2020. Google Scholar was searched. The inclusion criteria stated that studies were peer-reviewed, reported the experience of living with mesothelioma from the perspective of patients and carers and written in English. The Mixed-Methods Appraisal Tool was used to assess quality. The review protocol is registered on PROSPERO: CRD42020204726.

RESULTS

Twenty-five studies met the inclusion criteria. Following data extraction, a narrative synthesis identified three themes: the impact on the individual; the impact on informal carers and relationships; and interactions with professionals and systems. The physical and psychological symptom burden of mesothelioma on patients' lives was reported as high. Both the qualitative and quantitative literature highlighted that patients and carers may have different needs throughout the mesothelioma journey. Differences included psychological experiences and preferences regarding the timing of information and support provision. Patients and carers expected their health care professionals to be knowledgeable about mesothelioma or refer to those who were. Health care professionals that were compassionate, honest and supportive also positively influenced the experience of patients and carers living with mesothelioma. A lack of communication or misinformation was damaging to the patient-healthcare professional relationship. Continuity of care, coordinated care and good communication between treatment centres were widely reported as important in the literature. Fragmented care was identified as detrimental to the patient experience, increasing anxiety in patients. However, relationships with professionals were not only important in terms of co-ordinating care. There was also evidence that good relationships with healthcare professionals were beneficial to coping with the mesothelioma diagnosis.

CONCLUSION

The volume of mesothelioma experience research has grown over the past decade. This has led to our growing understanding of the complex needs and experiences of mesothelioma patients and carers. However, this review identified several evidence gaps.

A highly virulent variant of HIV-1 circulating in the Netherlands

We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log₁₀ increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Examining the effectiveness of Gateway-an out-of-court community-based intervention to reduce recidivism and improve the health and well-being of young adults committing low-level offences: study protocol for a randomised controlled trial

BACKGROUND

Young adult offenders represent a third of the UK prison population and are at risk of poor health outcomes including drug and alcohol misuse, self-harm and suicide. Court diversion interventions aim to reduce the negative consequences of formal criminal justice sanctions and focus resources on addressing the root causes of offending. Although diversions are widely used, evidence of their effectiveness has not yet been established. Hampshire Constabulary, working together with local charities, have developed the Gateway programme, an out-of-court intervention aimed at improving the life chances of young adults. Issued as a conditional caution, participants undertake a health and social care needs assessment, attend workshops encouraging analysis of own behaviour and its consequences and agree not to re-offend during the 16-week caution.

METHODS

This is a pragmatic, multi-site, parallel-group, superiority randomised controlled trial with a target sample size of 334. Participants are aged 18-24, reside in Hampshire and Isle of Wight and are being questioned for an eligible low-level offence. Police investigators offer potential participants a chance to receive the Gateway caution, and those interested are also invited to take part in the study. Police officers obtain Stage 1 consent and carry out an eligibility check, after which participants are randomised on a 1:1 basis either to receive Gateway or follow the usual process, such as court appearance or a different conditional caution. Researchers subsequently obtain Stage 2 consent and collect data at weeks 4 and 16, and 1 year post-randomisation. The primary outcome is the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Secondary outcomes include health status, alcohol and drug use, recidivism and resource use. The primary analysis will compare the WEMWBS score between the two groups at 12 months.

DISCUSSION

This pioneering trial aims to address the evidence gap surrounding diversion in 18-24-year-olds. The findings will inform law enforcement agencies, third sector organisations, policymakers and commissioners, as well as researchers working in related fields and with vulnerable target populations.

COVID-19 opens the door for right iliac fossa pain treatment pathway

INTRODUCTION

The COVID-19 pandemic has increased the risks of surgery and management of common surgical conditions has changed, with greater reliance on imaging and conservative management. The negative appendectomy rate (NAR) in the UK has previously remained high. The aim of this study was to quantify pandemic-related changes in the management of patients with suspected appendicitis, including the NAR.

METHODS

A retrospective study was performed at a single high volume centre of consecutive patients aged over five years presenting to general surgery with right iliac fossa pain in two study periods: for two months before lockdown and for four months after lockdown. Pregnant patients and those with previous appendectomy, including right colonic resection, were excluded. Demographic, clinical, imaging and histological data were captured, and risk scores were calculated, stratifying patients into higher and lower risk groups. Data were analysed by age, sex and risk subgroups.

RESULTS

The mean number of daily referrals with right iliac fossa pain or suspected appendicitis reduced significantly between the study periods, from 2.92 before lockdown to 2.07 after lockdown (p<0.001). Preoperative computed tomography (CT) rates increased significantly from 22.9% to 37.2% (p=0.002). The NAR did not change significantly between study periods (25.5% prior to lockdown, 11.1% following lockdown, p=0.159). Twelve (75%) out of sixteen negative appendectomies were observed in higher risk patients aged 16-45 years who did not undergo preoperative CT. The NAR in patients undergoing CT was 0%.

CONCLUSIONS

Greater use of preoperative CT should be considered in risk stratified patients in order to reduce the NAR.

Addressing current challenges in adult nursing: Describing a virtual consensus development project methodology

Aim

This article describes the development and implementation of a virtual Consensus development project to address current challenges in adult nursing care in the UK.

Design

This is a Consensus Development Project (CDP).

Methods

The five stages of this CDP were: develop questions (informed by PPI representatives and a documentary review), generate evidence reviews, recruit and orient the lay panel, host Consensus seminars, and consult with panel members and stakeholders.

Results

To the best of our knowledge, a CDP has not previously been conducted in a UK nursing context, and this is the first of its kind to be hosted virtually. This article contributes a detailed outline of the Consensus development methodology and constructive commentary to support future Consensus development projects. Learning points include reflections on the impact of hosting this event virtually, the relationship between the project coordinator and chair, and the composition of the lay panel.

Understanding the palliative care needs and experiences of people with mesothelioma and their family carers: An integrative systematic review

BACKGROUND

People with mesothelioma and their families have palliative care needs throughout the relatively short trajectory of their illness.

AIM

To describe the palliative care needs and experiences of people with mesothelioma and their family carers.

DESIGN

Integrative systematic review with narrative synthesis (PROSPERO: CRD42020190115).

DATA SOURCES

MEDLINE, CINAHL, PsycINFO and the Cochrane Library were searched for articles published between 01 January 2000 and 10 May 2020. Articles were included if they presented empirical studies or comprehensive reviews including information about the palliative care needs and experiences of people with mesothelioma and their family carers.

RESULTS

The search yielded 508 articles, 14 were included in the analysis. A cross cutting theme of 'uncertainty' was identified encompassing five themes: (1) organisation and co-ordination of services, (2) communication and information needs, (3) management of care needs and high symptom burden, (4) consideration of the impact of seeking compensation and (5) family carer needs. Our findings demonstrate that people with mesothelioma want a co-ordinated, team-based approach to palliative care with a named point of contact. Whilst carers value and benefit from early referral to specialist palliative care, this does not necessarily reflect the outcomes and views of patients.

CONCLUSION

The evidence base around the palliative care needs and experiences of people with mesothelioma and their carers needs to be strengthened. The results of this review support the need to develop a greater understanding about the role non-specialist palliative care clinicians' play in providing generalist palliative care for people with mesothelioma and their carers.

The impact of COVID-19 on work, training and well-being experiences of nursing associates in England: A cross-sectional survey

AIM

To explore how the COVID-19 pandemic affected nursing associate work, training and well-being experiences.

DESIGN

Cross-sectional survey.

METHODS

A survey of trainee and newly qualified nursing associates was completed in July 2020. Closed responses were analysed using descriptive statistics with inferential comparisons made between community and secondary care settings. Open questions were analysed thematically.

RESULTS

Sixty-four participants responded. Over half (53.2%) experienced an increased workload with 24.2% reporting extensions in their role. One third (32.3%) were redeployed, and a quarter (24.2%) did not feel safety concerns were adequately addressed when raised. Those working in the community reported significantly more concerns about staffing (p = .03), working overtime (p = .03), missed care (p = .02) and safety (p = .04). Despite this, many (75.8%) participants felt able to provide the same standards of care. Several spoke about enhanced teamwork, and the majority (96.8%) were not looking to leave their post.

Gender and the experiences of living with mesothelioma: A thematic analysis

PURPOSE

Mesothelioma is a terminal cancer caused by exposure to asbestos. As a cancer with a higher rate in men than women, women's experiences of living with mesothelioma are often underexplored. Furthermore, men's experiences are often taken for granted and therefore have remained underexplored. This paper considers men's and women's experiences across the mesothelioma pathway.

METHODS

This qualitative study incorporated semi-structured interviews with 13 men and 11 women living with mesothelioma. Telephone interviews took place between July and December 2019, and were audio recorded, transcribed and anonymised. Thematic analysis was used to analyse the data.

RESULTS

Three themes were developed in relation to the gendered experience of mesothelioma: familial responsibility and social perceptions; support preferences; and treatment and trials. Analysis suggests that men and women's sense of familial responsibility varied. Differences in priorities and motivations influenced approaches to seeking support, compensation and, making decisions around treatments and clinical trials.

CONCLUSIONS

The current study reports on how gender can influence the experience of living with mesothelioma. The findings indicate how the patients' role in their families and society can more broadly influence their experiences, choices and preferences. Nurses caring for mesothelioma patients need high quality research on which to base their practice. Recognition and an understanding of the underlyingfactors influencing patients' decision-making will enable nurses and other professionals to support their patients better.

Cerebral Venous Thrombosis in COVID-19: A New York Metropolitan Cohort Study

BACKGROUND AND PURPOSE

Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) infection is associated with hypercoagulability. We sought to evaluate the demographic and clinical characteristics of cerebral venous thrombosis among patients hospitalized for coronavirus disease 2019 (COVID-19) at 6 tertiary care centers in the New York City metropolitan area.

MATERIALS AND METHODS

We conducted a retrospective multicenter cohort study of 13,500 consecutive patients with COVID-19 who were hospitalized between March 1 and May 30, 2020.

RESULTS

Of 13,500 patients with COVID-19, twelve had imaging-proved cerebral venous thrombosis with an incidence of 8.8 per 10,000 during 3 months, which is considerably higher than the reported incidence of cerebral venous thrombosis in the general population of 5 per million annually. There was a male preponderance (8 men, 4 women) and an average age of 49 years (95% CI, 36-62 years; range, 17-95 years). Only 1 patient (8%) had a history of thromboembolic disease. Neurologic symptoms secondary to cerebral venous thrombosis occurred within 24 hours of the onset of the respiratory and constitutional symptoms in 58% of cases, and 75% had venous infarction, hemorrhage, or both on brain imaging. Management consisted of anticoagulation, endovascular thrombectomy, and surgical hematoma evacuation. The mortality rate was 25%.

CONCLUSIONS

Early evidence suggests a higher-than-expected frequency of cerebral venous thrombosis among patients hospitalized for COVID-19. Cerebral venous thrombosis should be included in the differential diagnosis of neurologic syndromes associated with SARS-CoV-2 infection.

Phase I trial of the MEK inhibitor selumetinib in combination with thoracic radiotherapy in non-small cell lung cancer

Background

The RAS/RAF/MEK/ERK signalling pathway has a pivotal role in cancer proliferation and modulating treatment response. Selumetinib inhibits MEK and enhances effects of radiotherapy in preclinical studies.

Patients and methods

Single-arm, single-centre, open-label phase I trial. Patients with stage III NSCLC unsuitable for concurrent chemo-radiotherapy, or stage IV with dominant thoracic symptoms, were recruited to a dose-finding stage (Fibonacci 3 + 3 design; maximum number = 18) then an expanded cohort (n = 15). Oral selumetinib was administered twice daily (starting dose 50 mg) commencing 7 days prior to thoracic radiotherapy, then with radiotherapy (6-6.5 weeks; 60-66 Gy/30-33 fractions). The primary objective was to determine the recommended phase II dose (RP2D) of selumetinib in combination with thoracic radiotherapy.

Results

21 patients were enrolled (06/2010-02/2015). Median age: 62y (range 50-73). M:F ratio 12(57%):9(43%). ECOG PS 0:1, 7(33%):14(67%). Stage III 16(76%); IV 5(24%). Median GTV 64 cm³ (range 1-224 cm³). 15 patients comprised the expanded cohort at starting dose. All 21 patients completed thoracic radiotherapy as planned and received induction chemotherapy. 13 (62%) patients received the full dose of selumetinib.In the starting cohort no enhanced radiotherapy-related toxicity was seen. Two patients had dose-limiting toxicity (1x grade 3 diarrhoea/fatigue and 1x pulmonary embolism). Commonest grade 3-4 adverse events: lymphopaenia (19/21 patients) and hypertension (7/21 patients). One patient developed grade 3 oesophagitis. No patients developed grade ≥3 radiation pneumonitis. Two patients were alive at the time of analysis (24 and 26 months follow-up, respectively). Main cause of first disease progression: distant metastases ± locoregional progression (12/21 [57.1%] patients). Six patients had confirmed/suspected pneumocystis jiroveci pneumonia.

Conclusion

We report poor outcome and severe lymphopenia in most patients treated with thoracic radiotherapy and selumetinib at RP2D in combination, contributing to confirmed/clinically suspected pneumocystis jiroveci pneumonia. These results suggest that this combination should not be pursued in a phase II trial.ClinicalTrials.gov reference: NCT01146756.

UK advanced practice nurses' experiences of the COVID-19 pandemic: a mixed-methods cross-sectional study

OBJECTIVE

The aim of the study was to understand the experiences of advanced practice nurses (APNs) in the UK during the 2020 COVID-19 pandemic, particularly in relation to safety, shortages and retention.

DESIGN

A cross-sectional, mixed-methods survey.

SETTING

APNs in any UK setting.

PARTICIPANTS

The survey was sent to an existing UK-wide cohort of APNs. 124 APNs responded (51%).

RESULTS

UK-based APNs in this study reported shortages of staff (51%) and personal protective equipment (PPE) (68%) during the first 3 months of the coronavirus outbreak. Almost half (47%) had considered leaving their job over the same 3 months. Despite difficulties, there were reports of positive changes to working practice that have enhanced care.

CONCLUSION

UK APNs report COVID-19-related shortages in staff and equipment across primary and secondary care and all regions of the UK. Shortages of PPE during a pandemic are known to be a factor in the development of mental health sequelae as well as a risk factor for increased turnover and retention issues. Half of APNs surveyed were considering a change in job. The UK risks a further crisis in staff morale and retention if this is not acknowledged and addressed. APNs also expressed concern about patients not receiving routine care as many specialties closed or reduced working during the crisis. However, there were also many examples of good practice, positive changes and innovation.

Factors that optimise the impact of continuing professional development in nursing: A rapid evidence review

OBJECTIVES

Continuing professional development is essential for healthcare professionals to maintain and acquire the necessary knowledge and skills to provide person centred, safe and effective care. This is particularly important in the rapidly changing healthcare context of the Covid-19 pandemic. Despite recognition of its importance in the United Kingdom, minimum required hours for re-registration, and related investment, have been small compared to other countries. The aim of this review is to understand the factors that optimise continuing professional development impact for learning, development and improvement in the workplace.

DESIGN

A rapid evidence review was undertaken using Arksey and O'Malley's (2005) framework; identifying a research question, developing a search strategy, extracting, collating and summarising the findings.

REVIEW METHODS

In addressing the question 'What are the factors that enable or optimise CPD impact for learning, development and improvement in the workplace at the individual, team, organisation and system level?' the British Nursing Index, the Cochrane Library, CINAHL, HTA database, King's Fund Library, and Medline databases were searched for key terms. A total of 3790 papers were retrieved and 39 were included.

RESULTS

Key factors to optimising the impact of nursing and inter-professional continuing development are; self-motivation, relevance to practice, preference for workplace learning, strong enabling leadership and a positive workplace culture. The findings reveal the interdependence of these important factors in optimising the impact of continuing professional development on person-centred care and outcomes.

CONCLUSION

In the current, rapidly changing, healthcare context it is important for educators and managers to understand the factors that enhance the impact of continuing professional development. It is crucial that attention is given to addressing all of the optimising factors in this review to enhance impact. Future studies should seek to measure the value of continuing professional development for people experiencing care, nurses and the wider organisation.

Overturning circulation, nutrient limitation, and warming in the Glacial North Pacific

Although the Pacific Ocean is a major reservoir of heat and CO₂, and thus an important component of the global climate system, its circulation under different climatic conditions is poorly understood. Here, we present evidence that during the Last Glacial Maximum (LGM), the North Pacific was better ventilated at intermediate depths and had surface waters with lower nutrients, higher salinity, and warmer temperatures compared to today. Modeling shows that this pattern is well explained by enhanced Pacific meridional overturning circulation (PMOC), which brings warm, salty, and nutrient-poor subtropical waters to high latitudes. Enhanced PMOC at the LGM would have lowered atmospheric CO₂-in part through synergy with the Southern Ocean-and supported an equable regional climate, which may have aided human habitability in Beringia, and migration from Asia to North America.

Determinants of nurse job dissatisfaction - findings from a cross-sectional survey analysis in the UK

Background

A lower recruitment and high turnover rate of registered nurses have resulted in a global shortage of nurses. In the UK, prior to the COVID-19 epidemic, nurses’ intention to leave rates were between 30 and 50% suggesting a high level of job dissatisfaction.

Methods

In this study, we analysed data from a cross-sectional mixed-methods survey developed by the Royal College of Nursing and administered to the nursing workforce across all four UK nations, to explore the levels of dissatisfaction and demoralisation- one of the predictors of nurses’ intention to leave. We carried out logistic regression analysis on available data in order to determine what impacts job dissatisfaction.

Results

In total, 1742 nurses responded to questions about working conditions on their last shift. We found that nearly two-thirds of respondents were demoralised. Nurses were five times more likely (OR 5.08, 95% CI: 3.82–6.60) to feel demoralised if they reported missed care. A perceived lack of support had nearly the same impact on the level of demoralisation (OR 4.8, 95% CI: 3.67–6.38). These findings were reflected in the qualitative findings where RNs reported how staffing issues and failures in leadership, left them feeling disempowered and demoralised.

Conclusion

A large proportion of nurses reported feeling dissatisfied and demoralised. In order to reduce the negative impact of dissatisfaction and improve retention, more research needs to investigate the relationship dynamics within healthcare teams and how the burden experienced by RNs when unsupported by managers impacts on their ability to provide safe, good-quality care. These findings predate the current Covid-19 pandemic outbreak which may have had a further detrimental effect on job satisfaction in the UK and other nation’s nursing workforce.

Mechanism of lung development in the aetiology of adult congenital pulmonary airway malformations

Congenital pulmonary airway malformations (CPAMs) are rare lung abnormalities that result in cyst formation and are associated with respiratory distress in infants and malignant potential in adults. The pathogenesis of CPAMs remains unknown but data suggest disruption of the normal proximo-distal programme of airway branching and differentiation. Here, we demonstrate that adult human CPAM are lined with epithelium that retains SOX-2 and thyroid transcription factor-1 immunohistochemical markers, characteristic of the developing lung. However, RALDH-1, another key marker, is absent. This suggests a more complex aetiology for CPAM than complete focal arrest of lung development and may provide insight to the associated risk of malignancy.

What are the psychological effects of mesothelioma on patients and their carers? A scoping review

OBJECTIVE

Despite recent advances in research, malignant mesothelioma remains an incurable and devastating disease, typically bringing shock and emotional distress to patients and carers. Little research has addressed the psychological impact on either group. This scoping review examines the current state of evidence on the psychological effects of mesothelioma on patients and carers, and identifies areas for further research.

METHODS

We searched PubMed, PsychINFO, CINAHL, the Cochrane Library and Web of Science for English-language peer-reviewed research articles published 1981 to 2019 reporting studies focussing on the psychological effects of mesothelioma on patients and carers. Following data extraction and quality appraisal, reflexive thematic analysis was used to identify themes.

RESULTS

Seventeen articles met the inclusion criteria. Carers' experiences were generally amalgamated with patients'. Three themes were developed. The Passing of Time included the importance of timing of interventions; delays in the medical journey; awareness of different time-phases in mesothelioma; and uncertainty/certainty. Dealing with Difficult Feelings reflected ubiquitous negative emotions, feelings about identity and states of being and associated coping strategies. Craving Good Communication covered issues related to sharing of information and to positive/negative aspects of communication.

CONCLUSIONS

Though limited, the evidence indicates that mesothelioma, with its high symptom-burden, incurability, rarity and asbestos-related causation, leads to complex and inter-relating psychological effects on patients and carers. These effects are both negative and positive. The sparse literature gives a partial picture and demonstrates an urgent need for more nuanced research. Studies exploring the experiences of specific groups are recommended, with particular attention required to carers.

0388 Predictors of Incident Reduced Sleep Efficiency in Community-Dwelling Older Women

Introduction

There is a paucity of longitudinal studies with sleep efficiency (SE) as an outcome measure. Our objective was to examine potential risk factors for incident reduced SE among community-dwelling women in late life.

Methods

We studied 700 women (mean age 82.5 [SD=3.0] years) with a SE ≥70% at the Year 16 (2002-04) visit of the Study of Osteoporotic Fractures with a follow-up measure of SE at the Year 20 (2006-08) visit. SE (percentage of time sleeping while in bed) at both visits was measured using a wrist actigraph with data collected for an average of four 24-hour periods. Women were classified as having incident reduced SE if they had SE &lt;70% at Year 20. Logistic regression was used to estimate the associations between potential risk factors (demographics, lifestyle, use of medications, self-reported medical conditions, functional impairment, frailty, mental and physical health) at Year 16 and reduced SE at Year 20. The association of each candidate risk factor with reduced SE at Year 20 was examined in models adjusted for age, clinical site and continuous SE at Year 16. Candidate risk factors with Benjamin Hochberg false-discovery rate q-values &lt;0.10 were included in a final multivariate model.

Results

Among the 700 eligible women, 62 (8.9%) developed incident reduced SE between the Year 16 and Year 20 visits. After adjusting for age, site and baseline SE, antidepressant use [OR=3.06; 95% CI: 1.50-6.25], benzodiazepine use [OR=2.97; 95% CI: 1.30-6.80] and the presence of hypertension [OR=2.83; 95% CI: 1.47-5.45] at Year 16 were independently associated with a higher odds of having reduced SE at follow-up.

Conclusion

These findings suggest that antidepressant use, benzodiazepine use and hypertension are risk factors or markers for the development of reduced sleep efficiency in older women. Future studies are warranted to examine the underlying mechanisms for these associations.

Support

The Study of Osteoporotic Fractures (SOF) is supported by National Institutes of Health funding. The National Institute on Aging (NIA) provides support under the following grant numbers: R01 AG005407, R01 AR35582, R01 AR35583, R01 AR35584, R01 AG005394, R01 AG027574, and R01 AG027576.

Unusually high α-proton acidity of prolyl residues in cyclic peptides

The acidity of the α-proton in peptides has an essential role in numerous biochemical reactions and underpins their stereochemical integrity, which is critical to their biological function. We report a detailed kinetic and computational study of the acidity of the α-proton in two cyclic peptide systems: diketopiperazine (DKP) and triketopiperazine (TKP). The kinetic acidity (protofugality) of the α-protons were determined though hydrogen deuterium exchange studies in aqueous solutions. The acidities of the α-proton in prolyl residues were increased by 3–89 fold relative to other amino acid residues (prolyl > glycyl ≫ alanyl > tyrosyl). Experimental and computational evidence for the stereoelectronic origins of this enhanced prolyl reactivity is presented. TKPs were 10⁶-fold more reactive than their DKP analogues towards deprotonation, which we attribute to the advanced development of aromaticity in the earlier transition state for proton transfer in these cases. A Brønsted linear free energy analysis of the reaction data was conducted to provide estimates of α-proton pK_as.

Kinetic and computational studies reveal that prolyl residues in cyclic peptides are substantially more acidic than other residues due to a stereoelectronic effect.

Promoting the health of children and young people who migrate: reflections from four regional reviews

Calls to enhance the health of migrant population sub-groups are strengthening, with increasing evidence documenting the relationship between migration and health outcomes. Despite the importance of migration to global health promotion, little research has focused on the health experiences of young migrants. As part of a Worldwide University Network project, we completed four systematic reviews examining the existing evidence base on the health experiences of children and young people who migrate. In this commentary, we share commonalities with the international evidence but also reflect on some of the challenges, omissions and limitations. These insights expose significant gaps and methodological shortcomings in the evidence - providing space for new research that seeks to identify the influences on migrant children's health.

Method Extension Study to Validate Applicability of AOAC Official Method 996.14 Assurance® Polyclonal Enzyme Immunoassay for Detection of Listeria monocytogenes and Related Listeria spp. from Environmental Surfaces: Collaborative Study

Test portions from 3 environmental surface types, representative of typical surfaces found in a food production facility, were analyzed by the Assurance®Listeria Polyclonal Enzyme Immunoassay (EIA) and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) culture method for Listeria monocytogenes and related Listeria species. In all cases, naturally contaminated environmental test samples were collected from an actual food production facility by sponge or swab. Test samples from concrete surfaces were collected by both swab and sponge; sponge test samples were collected from rubber surfaces, and swabs were used to sample steel surfaces. Test portions from each surface type were simultaneously analyzed by both methods. A total of 23 collaborators, representing government agencies, as well as private industry in both the United States and Canada, participated in the study. During this study, a total of 550 test portions and controls was analyzed and confirmed, of which 207 were positive and 336 were negative by both methods. Six test portions were positive by culture, but negative by the EIA. Three test portions were negative by culture, but positive by the EIA. Two test portions were negative by EIA and by culture, but confirmed positive when EIA enrichment broths were subcultured to selective agars. The data reported here indicate that the Assurance®Listeria EIA method and the USDA/FSIS culture method are statistically equivalent for detection of L. monocytogenes and related Listeria species from environmental surfaces taken by sponges or swabs.

Method Extension Study to Validate Applicability of AOAC Official Method 997.03 Visual Immunoprecipitate Assay (VIP®) for Listeria monocytogenes and Related Listeria spp. from Environmental Surfaces: Collaborative Study

Test portions from 3 environmental surface types, representative of typical surfaces found in a food production facility, were analyzed by the Visual Immunoprecipitate assay (VIP®) and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) culture method for Listeria monocytogenes and related Listeria species. In all cases, naturally contaminated environmental test samples were collected from an actual food production facility by sponge or swab. Test samples from concrete surfaces were collected by both swab and sponge; sponge test samples were collected from rubber surfaces, and swabs were used to sample steel surfaces. Test portions from each surface type were simultaneously analyzed by both methods. A total of 27 laboratories, representing government agencies as well as private industry in both the United States and Canada, participated in the study. During this study, a total of 615 test portions and controls was analyzed and confirmed, of which 227 were positive and 378 were negative by both methods. Nine test portions were positive by culture, but negative by the VIP. Five test portions were negative by culture, but positive by the VIP. Four test portions were negative by VIP and by culture, but confirmed positive when VIP enrichment broths were subcultured to selective agars. The data reported here indicate that the VIP method and the USDA/FSIS culture method are statistically equivalent for detection of L. monocytogenes and related Listeria species from environmental surfaces taken by sponges or swabs.
