Unrecognized volatile and semi-volatile organic compounds from brake wear

Motor vehicles are among the major sources of pollutants and greenhouse gases in urban areas and a transition to "zero emission vehicles" is underway worldwide. However, emissions associated with brake and tire wear will remain. We show here that previously unrecognized volatile and semi-volatile organic compounds, which have a similarity to biomass burning emissions are emitted during braking. These include greenhouse gases or, these classified as Hazardous Air Pollutants, as well as nitrogen-containing organics, nitrogen oxides and ammonia. The distribution and reactivity of these gaseous emissions are such that they can react in air to form ozone and other secondary pollutants with adverse health and climate consequences. Some of the compounds may prove to be unique markers of brake emissions. At higher temperatures, nucleation and growth of nanoparticles is also observed. Regions with high traffic, which are often disadvantaged communities, as well as commuters can be impacted by these emissions even after combustion-powered vehicles are phased out.

Exploring parents' experiences and holistic needs following late miscarriage: a narrative systematic review

BACKGROUND

Up to 2% of all pregnancies result in pregnancy loss between 14 + 0 and 23 + 6 weeks' gestation, which is defined as 'late miscarriage'. Lack of consensus about definition of viability paired with existing multiple definitions of perinatal loss make it difficult to define the term 'late miscarriage'. Parents who experience late miscarriage often have had reassuring scan-milestones, which established their confidence in healthy pregnancy progression and identity formation, which socially integrates their baby into their family. The clinical lexicon alongside the lack of support offered to parents experiencing late miscarriage may disclaim their needs, which has potential to cause adverse psychological responses.

AIM

To review what primary research reports about parents' experiences and their perceived holistic needs following late miscarriage.

METHODS

A narrative systematic review was carried out. Papers were screened based on gestational age at time of loss (i.e. between 14 + 0 and 23 + 6 weeks' gestation). The focus was set on experience and holistic needs arising from the loss rather than its clinical care and pathophysiology. Studies were selected using PRISMA-S checklist, and quality assessed using the Critical Appraisal Skills Program (CASP) tool. Thematic analysis was used to guide the narrative synthesis of findings.

RESULTS

Six studies met the inclusion criteria. Three main themes emerged: communication and information-giving; feelings post-event; and impact of support provision.

CONCLUSION

Literature about the experience of late miscarriage is scarce, with what was found reporting a lack of compassionate and individually tailored psychological follow-up care for parents following late miscarriage. Hence, more research in this arena is required to inform and develop this area of maternity care provision.

A pilot cluster randomised controlled trial of a peer-delivered outreach community-based smoking cessation intervention for women living in disadvantaged communities in Ireland

INTRODUCTION

The health of women in rural communities is adversely impacted by increased rates of tobacco use linked to socio-economic disadvantage (SED) and by limited access to services. We Can Quit (WCQ) is a smoking cessation programme delivered by trained lay women (community facilitators) in local communities, which was developed using a Community-based Participatory Research (CBPR) approach and tailored to women living in SED areas of Ireland.

METHODS

The We Can Quit2 (WCQ2) pilot cluster randomised controlled trial with an inbuilt process evaluation was conducted in four matched pairs of urban and semi-rural SED districts (8-10,000 women per district) to assess feasibility. Districts were independently randomised to WCQ (group support +/- nicotine replacement therapy), or to individual support delivered by health professionals.

RESULTS

Findings showed that that the WCQ outreach programme is acceptable and feasible to implement for smoking women living in disadvantaged neighbourhoods. A secondary outcome of smoking abstinence (self-report + biochemical validation) demonstrated 27% abstinence in the intervention group versus 17% in usual care at end of programme. Low literacy was highlighted as a major barrier to participants' acceptability.

DISCUSSION

The design of our project provides an affordable solution for governments in prioritising outreach smoking cessation in vulnerable populations in countries with rising rates of female lung cancer. Our community-based model using a CBPR approach empowers local women to become trained to deliver smoking cessation programmes within their own local communities. This provides a foundation to create a sustainable and equitable way to address tobacco use in rural communities.

Symptom burden, management and treatment goals of people with MS spasticity: Results from SEEN-MSS, a large-scale, self-reported survey

BACKGROUND

Spasticity occurs frequently in people with multiple sclerosis (PwMS) and may affect non-physical aspects of life. However, there is a paucity of data assessing the full impact of spasticity in PwMS.

OBJECTIVE

This survey of PwMS and spasticity (PwMSS) was undertaken to understand the impact of spasticity in physical, functional, emotional, and social domains.

METHODS

SEEN-MSS (Symptoms and Emotions Exploration Needed in Multiple Sclerosis Spasticity), an online survey, was developed in collaboration with three US-based MS organizations (conducted February-April 2021).

RESULTS

Survey was completed by 1,177 PwMSS, 78% female, mean age 56.8yrs, 16.8yrs from MS diagnosis, 11.5yrs with spasticity. Considering day-to-day goals of treatment, respondents reported that managing symptoms(46%) was nearly as important as slowing disease progression(54%). Most reported spasticity was a constant reminder of their MS. Participants reported that spasticity limited daily activities (92%), caused pain (92%), impaired sleep (89%) and negatively impacted emotional well-being (87%). Spasticity fostered a sense of dependence (61%), isolation (40%), decline in self-confidence (75%), self-image (70%), and social connection (62%).

CONCLUSIONS

Spasticity has wide-reaching negative impacts on multiple aspects of life, causing substantial burden for PwMSS. Results emphasize the need to fully understand the burden of spasticity and addressing individual needs of PwMSS.

Genetic evaluation of paediatric nephrocalcinosis: phenotype-driven genetic panels reveal a rare diagnosis

Monogenic causes of paediatric nephrocalcinosis are associated with extensive phenotypic variability. We report a 14-year-old male who presented at 8 years of age with incidentally identified nephrocalcinosis alongside growth impairment and dental anomalies. Extensive genetic investigation confirmed a molecular diagnosis of Bartter syndrome type II. This is exceptional in both late presentation and the presence of amelogenesis imperfecta, a very rare association of inherited tubulopathies. Details of the nephrocalcinosis gene panel analysed and associated phenotypes are presented to highlight the utility of a phenotype-driven genetic panel in resolving an atypical presentation of nephrocalcinosis, allowing precise diagnosis, tailored therapy and prognostication.

Peer-Delivery of a Gender-Specific Smoking Cessation Intervention for Women Living in Disadvantaged Communities in Ireland We Can Quit2 (WCQ2)-A Pilot Cluster Randomized Controlled Trial

Introduction

We Can Quit” (WCQ) is community-based stop-smoking program delivered by trained community facilitators, based on the socio-ecological framework and developed using a Community-based Participatory Research approach, targeting women living in socioeconomically disadvantaged (SED) areas of Ireland.

Aims and Methods

The We Can Quit2 (WCQ2) pilot trial assessed the feasibility of WCQ. A pragmatic cluster randomized controlled trial with a process evaluation WCQ2, was conducted in four matched pairs of SED districts (8–10 000 women per district). Districts were independently randomized to WCQ (group support + nicotine replacement therapy), or to individual support delivered by health professionals. Participants were adult women smokers interested in quitting, who were living or working in trial districts. Recruitment of districts and 194 women in four waves (49 women per wave); retention at 12 weeks and 6 months; fidelity to intervention delivery and acceptability of trial-related processes were assessed. Validated smoking abstinence at 12-week and 6-month post-intervention was recorded, missing data assumed as continued smoking.

Results

Eight districts were recruited. 125/188 (66.5%) eligible women consented. The 49 women target was reached in wave4. Retention at 12 weeks was (Intervention [I]: 55.4%; Control [C]: 51.7%), at 6 months (I: 47.7%; C: 46.7%). Smoking abstinence at 12 weeks was (I: 23.1%, [95% CI: 14.5 to 34.7]; C: 13%, [95% CI: 6.9 to 24.1]). 83.8% of session activities were delivered. Trial-related processes were acceptable to facilitators. Low literacy was highlighted as a barrier for participants’ acceptability.

Conclusions

WCQ was feasible to deliver by trained facilitators and indicated a positive direction in abstinence rates. Low literacy will need to be addressed in a future trial design.

Implications

This pilot trial showed that a stop-smoking intervention tailored to a group of women smokers living in SED areas which was delivered by trained local women within their local communities was feasible. Furthermore, although not formally compared, more WCQ women were abstinent from smoking at the end of treatment. The results are relevant to enhance the design of a fully powered effectiveness trial, and provide important evidence on the barriers to deliver a tailored smoking cessation service to SED women smokers in Ireland.

Prenatal chromosome microarray: 'The UK experience'. A survey of reporting practices in UK genetic services (2012-2019)

BACKGROUND

The value of chromosome microarray (CMA) in the prenatal detection of significant chromosome anomalies is well-established. To guide the introduction of this technique in routine clinical practice, the Joint Committee on Genomics in Medicine developed national UK guidelines for reporting prenatal CMA in 2015.

OBJECTIVE

To evaluate the UK experience of utilising prenatal CMA.

METHOD

A 36-item survey was distributed to all UK clinical genetics services (n = 23) in March 2019 requesting information pertaining to experience since diagnostic testing commenced and current practice (March 2018 to March 2019).

RESULTS

Eighteen UK genetics services currently offer prenatal CMA. A total of 14,554 tests had been performed. A pathogenic copy number variant was identified in 7.8% of tests overall, though the diagnostic rate increased to 8.4% in the final year of the survey. Variants of uncertain significance (VUS) were reported in 0.7% of tests, and 'actionable' incidental findings in 0.12%.

CONCLUSION

Diagnostic rate has improved over time, while reporting of VUS has decreased. Reviewing survey responses at a national level highlights variation in testing experience and practice, raising considerations both for future guideline development and implementation of other novel techniques including prenatal whole exome sequencing.

37 Factors Influencing Mealtime Care for People with Dementia Living in Care Homes: An Ethnographic Study

Introduction

More and more people with dementia are living in care homes. Often they depend on care home staff for help with eating and drinking. It is essential that care home staff are able to provide good care at mealtimes. This study used ethnography to identify factors influencing mealtime care for this population.

Methods

Over twenty-five hours of mealtime observations were conducted in two UK care homes with diverse characteristics. Observations focused on interactions between care home staff and residents living with dementia. Twenty-two semi-structured interviews were carried out with care home staff, family carers, and visiting health and social care professionals, to explore mealtime care from their perspectives. The study used a constant comparison approach, so that data from early observations and interviews were explored in more depth subsequently.

Results

Five factors were identified which influenced mealtime care for people with dementia living in care homes. These were: environment (such as background music and building layout); kitchen and food (including connectivity between kitchen staff and others); staffing (for example: staff ratios and allocation); knowledge and support (including training, resources and supportive culture); and relationship with wider care team (such as family involvement, and the role of visiting health and social care professionals).

Conclusions

This study is part of a bigger project which will develop a staff training intervention to improve mealtime care for people with dementia living in care homes. The intervention will be informed by these findings, and by complementary evidence on good practice in mealtime care (from primary and secondary studies). It is anticipated that good mealtime care may improve quality of life for care home residents, and reduce hospital admissions.

ICD-11 complex Post Traumatic Stress Disorder (CPTSD) in parents with perinatal bereavement: Implications for treatment and care

INTRODUCTION

The 11th revision of the WHO International Classification of Diseases (ICD-11) has identified Complex PTSD (CPTSD) as a new condition.

AIM

To explore whether the new diagnosis of CPTSD (ICD11) is relevant to women who have experienced perinatal bereavement and to advance knowledge about the acceptability, feasibility and perceived impact of delivering an innovative flexible Compassionate Focused Therapy (CFT) informed treatment package to alleviate symptoms of this condition.

METHODS

A mixed methods study using survey and interviews was conducted. Participants first completed the International Trauma Questionnaire (ITQ) to assess if they met the criteria for PTSD or CPTSD (n=72), and subsequent semi-structured interviews (n=12) identified participants' views about different treatment approaches.

PARTICIPANTS

A convenience sample of women who had experienced perinatal bereavement were recruited from one geographical region in Scotland.

DATA COLLECTION

Information was gathered about trauma experiences related to perinatal bereavement; participants' levels of PTSD or CPTSD using the ITQ; and views regarding the features of treatment options. In-depth interviews with women (n=12) and a focus group with staff (n=5) were also conducted.

FINDINGS

Of 74 participants (n=74) who fully completed the ITQ, 10.8% (n=8) met the criteria for PTSD and 29.7% (n=22) for CPTSD, equating to a total of 40.5% of participants experiencing traumatic stress. Results suggest that CPTSD is a more common condition than PTSD in people with perinatal bereavement, with qualitative data suggesting that CFT and EMDR can be useful and acceptable interventions for this population group.

CONCLUSION

A feasibility study is recommended next to evaluate acceptability of trial processes in preparation for a definitive randomised controlled trial of a new flexible CFT informed treatment package to address PTSD and CPTSD in people with perinatal bereavement.

RECOMMENDATIONS FOR PRACTICE

Routine assessment of ICD-11 CPTSD is recommended in this population group.

A composite neonatal adverse outcome indicator using population-based data: an update

Introduction

Severe morbidity rates in neonates can be estimated using diagnosis and procedure coding in linked routinely collected retrospective data as a cost-effective way to monitor quality and safety of perinatal services. Coding changes necessitate an update to the previously published composite neonatal adverse outcome indicator for identifying infants with severe or medically significant morbidity.

Objectives

To update the neonatal adverse outcome indicator for identifying neonates with severe or medically significant morbidity, and to investigate the validity of the updated indicator.

Methods

We audited diagnosis and procedure codes and used expert clinician input to update the components of the indicator. We used linked birth, hospital and death data for neonates born alive at 24 weeks or more in New South Wales, Australia (2002–2014) to describe the incidence of neonatal morbidity and assess the validity of the updated indicator.

Results

The updated indicator included 28 diagnostic and procedure components. In our population of 1,194,681 live births, 5.44% neonates had some form of morbidity. The rate of morbidity was greater for higher-risk pregnancies and was lowest for those born at 39–40 weeks’ gestation. Incidence increased over the study period for overall neonatal morbidity, and for individual components: intravenous infusion, respiratory diagnoses, and non-invasive ventilation. Severe or medically significant neonatal morbidity was associated with double the risk of hospital readmission and 10 times the risk of death within the first year of life.

Conclusion

The updated composite indicator has maintained concurrent and predictive validity and is a standardised, economic way to measure neonatal morbidity when using population-based data. Changes within individual components should be considered when examining longitudinal data.

A systematic integrative review of the literature on midwives and student midwives engaged in problematic substance use

OBJECTIVE

The objective of this systematic integrative review was to review the literature in relation to problematic substance use (PSU) in midwifery populations. Associated aims were to aggregate existing knowledge about midwives and student midwives' personal engagement in PSU, to generate a holistic conceptualisation and synthesis of the existing literature regarding midwives and student midwives personally engaged in PSU and to present new understandings and perspectives to inform the development of future research questions. This review is the first of its kind.

DESIGN

Systematic searches were conducted in CINAHL, Academic Search Complete, MEDLINE, PSYCInfo, Scopus and the Cochrane Library. Findings were grouped into themes and subthemes relating to both midwives and student midwives and then analysed critically in relation to the wider literature. A quality assessment was conducted using the Mixed Methods Appraisal Tool (MMAT). The PRISMA statement was used to guide reporting.

SETTING

Included studies were conducted in Scotland, Ireland, Australia and New Zealand.

PARTICIPANTS

Studies included a total of 6,182 participants.

FINDINGS

A total of 3 studies were included. All included study types comprised quantitative survey designs, yet one also included a mixed methods design with the use of semi structured interviews. Two overarching themes emerged relating to both midwives and student midwives engaged in problematic substance use. For midwives, three subthemes are described: harmful daily alcohol consumption, working hours and harmful daily alcohol consumption and features associated with harmful daily alcohol consumption. For student midwives, two subthemes are presented: escape avoidance and alcohol, tobacco and cannabis use.

KEY CONCLUSIONS

There is limited evidence available in relation to problematic substance use in midwifery populations in comparison to that available for other healthcare populations. Further research is required, and could usefully focus upon midwives and student midwives as distinct professions to be separated out from the wider healthcare workforce.

IMPLICATIONS FOR PRACTICE

Problematic substance use among the healthcare workforce is associated with an increase in medical errors and inadequate care. Those affected can be reluctant to seek help, experience psychological distress and even contemplate suicide. Whilst evidence remains lacking for midwifery populations, they form a part of the general healthcare workforce and are exposed to similar workplace stressors. As such, it is likely that they too would be affected in similar ways.

Familial dilated cardiomyopathy associated with pathogenic TBX5 variants: Expanding the cardiac phenotype associated with Holt-Oram syndrome

Holt-Oram syndrome (HOS) is a rare, autosomal dominant disorder caused by heterozygous pathogenic variants in cardiac T-box transcription factor, TBX5. Classically, it is associated with upper limb malformations and variable cardiac abnormalities. Limb manifestations are considered to be invariably present, ranging in severity from limitation in movement, to triphalangeal thumbs, absent thumbs, shortened forearms, or phocomelia. Cardiac involvement is characterized by congenital heart defects, most commonly septal structural malformations, and conduction system disease. Recently, novel TBX5 variants have also been reported in association with dilated cardiomyopathy (DCM). In this context, we report eight individuals from four unrelated families, in whom pathogenic variants in TBX5 segregated with an atypical HOS phenotype. Affected individuals exhibit relatively mild skeletal features of HOS, with a predominant cardiac phenotype, which includes several individuals affected by non-ischaemic DCM. To our knowledge, these represent the first reported cases of DCM in families with skeletal features of HOS, some of whom also harbored variants previously linked to a classical HOS phenotype (p. Arg279* and p.Arg237Gln). This finding supports diverse roles of TBX5 in cardiovascular development and function, and confirms the importance of long-term cardiac surveillance for individuals affected by HOS. Furthermore, these families highlight the wide phenotypic variability of HOS, which may include comparatively mild upper limb findings in respect to cardiac manifestations.

The Success and Evolution of a Urological "Boot Camp" for Newly Appointed UK Urology Registrars: Incorporating Simulation, Nontechnical Skills and Assessment

BACKGROUND

Urological training has dramatically changed in recent years. Training durations are shorter and a drive toward consultant led care has reduced trainees experience. Within the UK, approximately 50 registrars annually embark on a 5-year Urology training programme, with variable levels of basic urological experience.

OBJECTIVE

To describe a simulation programme aimed at delivering the knowledge and skills necessary to safely and effectively start working as a registrar in Urology by intensive training with a 1:1 faculty to delegate ratio.

DESIGN, SETTING, AND PARTICIPANTS

Our course content mirrors the UK training syllabus for junior Urology registrars. We delivered 8 modules over a 4-day programme with a fifth day of assessments. Delegates level of urological knowledge, operative competency and confidence pre-, immediately post-training and at 3-months postcourse were assessed. Objective delegate and faculty feedback was also collected. Technical skills modules include; inguinoscrotal surgery, ureteroscopy, transurethral resection, urodynamics, and Botox administration as well as basic reconstructive and laparoscopic operative skills. "Nontechnical" skills included simulated ward round, out-patient, and emergency scenarios.

RESULTS

Feedback from delegates and faculty members has been overwhelmingly positive. We have used this feedback to tailor the content of the course for following years. An increased knowledge level (based on mean examination scores [precourse 55.5%, postcourse 70.1%]) and operative competency was observed in all skills assessed (transurethral resection of the prostate, transurethral resection of bladder tumor, Ureteroscopy, laparoscopic skills, and instrument assembly). Operative confidence was increased immediately and at 3-months postcourse.

CONCLUSIONS

Our "boot camp" course provides a realistic introduction and foundation to begin Urological practice. Being delivered at the beginning of the training scheme, prior to intensive patient exposure, registrars are in an optimum position to develop their newly acquired knowledge and skills to enhance training and intends to improve patient safety and satisfaction.

22 Poor management of breeding herd replacements is a key factor in poor sow lifetime productivity: Gilty as charged

Recently published research on gilt development using contemporary commercial dam-lines has confirmed: 1) That the growth performance of gilts is rarely below the lifetime growth rate of 0.55 kg.d that would limit the onset of sexual maturity; 2) The majority of gilts provided direct daily contact with mature boars from 160 days of age reach puberty by 200 days of age and represent a normal distribution of “early responders”; 3) Gilts that respond later to boar stimulation have poorer lifetime fertility and tend to be over weight at breeding; 4) Pubertal responses to direct boar contact are significantly higher than responses to fenceline contact with boars; 5) Even if pubertal responses to direct boar contact are delayed in particular cohorts of gilts, good pubertal responses to exogenous, low-dose eCG/hCG treatments (PG600) allow efficient replacement gilt flows to be maintained in most commercial situations; 6) Delaying breeding until second observed estrus, and providing at least 10 days of acclimation to individual stall accommodation, maximizes first litter performance. When gilts were managed in purpose designed facilities that allowed daily records of vulval and behavioral responses to effective boar stimuli to be recorded, the lifetime reproductive performance of know pubertal gilts entering the breeding herd exceeded industry benchmarks. Of 2,374 naturally cyclic and 741 PG600-induced gilts delivered to the breeding herd, 97.6 and 95.7%, respectively, were bred, 94.7 and 92.0%, respectively, farrowed a first litter and 70.6 and 65.3%, respectively, farrowed a fourth litter. In terms of key factors other than reproductive performance that affect retention rate, another recent large-scale study of commercial replacement gilts derived from multiplication sows with a known litter birth weight phenotype confirmed data based on individual gilt birth weight, in that high growth rates linked to heavy weights at breeding were a major risk factor for early removal from the breeding herd. Therefore, poor gilt management must still be viewed as a major factor limiting breeding herd performance.

17 Effects of birth traits, physical or fenceline boar exposure and group size on pubertal measures and lifetime fertility of replacement gilts

In experiment 1, prepubertal gilts with (n = 264) and without (n = 43) birth records received Fenceline (FBE) or Physical (PBE) Boar Exposure (BE) in a Boar Exposure Area (BEAR). At 185 d of age, gilts (13/pen) received BE for 15 min/d for 3 wk. At the start of Week 3, anestrual gilts received PG600 or no-PG600 (Control). At estrus, females were moved into stalls and inseminated at 2nd heat. Gilts born in larger litters were lighter (r = -0.26) while heavier pigs grew faster to puberty (r = 0.25). PBE increased estrus in Week 1 (38%) over FBE (28%). In Week 3, PBE-PG600 increased estrus (79.9%) compared with PBE- Control (36.2%), while FBE-PG600 and Control did not differ (52.7 vs. 42.5%). By 6 wk, estrus tended to be greater (P < 0.08) for PBE (91.2%) than FBE (83.2%). Reduced fertility associated with: 1) small birth litter; 2) heaviest birthweight; 3) slower growth rate; 4) delayed puberty and age at 1st service; and 5) abnormal estrus interval. Experiment 2 tested the pubertal response to PBE or FBE with 10 or 20 gilts/pen. Gilts (n = 180) at 168 d with 1.8 m2 floor space received BE once/d for 15 min for 1–3 wk. At the start of Week 3, anestrual gilts received PG600. Estrus in Week 1 (7.3%) did not differ, but a BE x Pen effect occurred in Week 2 (estrus range: 15–34%). In Week 3, PG600 increased estrus (P < 0.03) in Pens of 10 (83.7%) compared to Pens of 20 (64.1%). BE method had no effect and Pens of 10 had greater estrus (P = 0.05) than Pens of 20 (88.3 vs 75.8%). These results indicated that use of PBE, a BEAR, smaller group size, and PG600 can be used in combinations to enhance puberty induction. Birth and pubertal measures influenced service and farrowing rate, litter size, and age at removal.

IL-1 receptor antagonist, anakinra, prevents myocardial dysfunction in a mouse model of Kawasaki disease vasculitis and myocarditis

Kawasaki disease (KD) vasculitis is an acute febrile illness of childhood characterized by systemic vasculitis of unknown origin, and is the most common cause of acquired heart disease among children in the United States. While  histological evidence of myocarditis can be found in all patients with acute KD, only a minority of patients are clinically symptomatic and a subset demonstrate echocardiographic evidence of impaired myocardial function, as well as increased left ventricular mass, presumed to be due to myocardial edema and inflammation. Up to a third of KD patients fail to respond to first-line therapy with intravenous immunoglobulin (IVIG), and the use of interleukin (IL)-1 receptor antagonist (IL-1Ra, anakinra) is currently being investigated as an alternative therapeutic approach to treat IVIG-resistant patients. In this study, we sought to investigate the effect of IL-1Ra on myocardial dysfunction and its relation to myocarditis development during KD vasculitis. We used the Lactobacillus casei cell-wall extract (LCWE)-induced murine model of KD vasculitis and investigated the effect of IL-1Ra pretreatment on myocardial dysfunction during KD vasculitis by performing histological, magnetic resonance imaging (MRI) and echocardiographic evaluations. IL-1Ra pretreatment significantly reduced KD-induced myocardial inflammation and N-terminal pro B-type natriuretic peptide (NT-proBNP) release. Both MRI and echocardiographic studies on LCWE-injected KD mice demonstrated that IL-1Ra pretreatment results in an improved ejection fraction and a normalized left ventricular function. These findings further support the potential beneficial effects of IL-1Ra therapy in preventing the cardiovascular complications in acute KD patients, including the myocarditis and myocardial dysfunction associated with acute KD.

Disempowered midwives and traumatised women: Exploring the parallel processes of care provider interaction that contribute to women developing Post Traumatic Stress Disorder (PTSD) post childbirth

BACKGROUND

Around 4% of women develop Post Traumatic Stress Disorder Post Childbirth (PTSD-PC). During childbirth a woman's perception of her care provider's interpersonal verbal and nonverbal relationship behaviours, termed 'Quality of Provider Interaction' are significantly associated with the development of PTSD-PC.

AIMS

To understand how women who develop PTSD-PC and midwives, experience their interactions during care provision. In particular, how they feel during their interactions and what this means to them.

METHODS

The qualitative method of Interpretative Phenomenological Analysis that incorporates a reflective approach, was used to gain deep understanding of the lived experience of care provider interaction. Six women who met full diagnostic criteria for PTSD-PC and six midwives who provided intrapartum care, participated in individual face-to-face interviews.

RESULTS

Two key findings were identified: 1) Failing to recognise and meet the human needs of both women and midwives, results in poor quality interactions from midwives and poor perception of care provider interaction by women; 2) The study groups of women and midwives both identified the quality of their relationship as central to positive interactions. RECOMMENDATIONS FOR PRACTICE: (1) Raise the status of psychological wellbeing for childbearing women and make it of equal importance to physical wellbeing, with clear focus upon care provider interaction; (2) Create a midwife centred system that enables midwives to provide optimal care provider interaction and improve relationship-based care; and (3) Challenge underlying toxic cultures that currently persist in the maternity services system, which undermine the work of midwives and consequently the experience of women.

CONCLUSION

Failure to recognise and meet the human and relationship needs of both childbearing women and midwives contributes to poor care provider interactions offered by midwives and negative perceptions of care provider interactions by women. In response, NHS maternity services need to highlight the importance of the quality of care provider interaction alongside perinatal psychological wellbeing. This requires improved working environments for midwives, so they can optimise their quality of interaction with childbearing women. This will in turn impact upon the incidence and levels of trauma and PTSD-PC experienced by women.

PTSD post-childbirth: a systematic review of women's and midwives' subjective experiences of care provider interaction

OBJECTIVE

Review primary research regarding PTSD Post-Childbirth (PTSD-PC) that focussed on Quality of Provider Interaction (QPI) from the perspective of women who developed PTSD-PC, or midwives.

BACKGROUND

Up to 45% of women find childbirth traumatic. PTSD-PC develops in 4% of women (18% in high-risk groups). Women's subjective experiences of childbirth are the most important risk factor in the development of PTSD-PC, with perceived QPI being key.

METHODS

A systematic search was performed for PTSD-PC literature. Reviewed papers focussed on either women's subjective childbirth experiences, particularly QPI, or midwives' perspectives on QPI. Study quality was assessed using the Critical Appraisal Skills Programme (CASP) tools, and a narrative synthesis of findings produced.

RESULTS

Fourteen studies were included. Three features of QPI contribute towards developing PTSD-PC: interpersonal factors; midwifery care factors; and lack of support.

CONCLUSION

QPI is a significant factor in the development of PTSD-PC and the identified key features of QPI have potential to be modified by midwives. The development of guidelines for midwives should be grounded on evidence highlighted in this review, along with further high-quality qualitative research exploring QPI from the perspective of women with PTSD-PC, but also midwives' knowledge and needs regarding their role within QPI.

Altered eating: a definition and framework for assessment and intervention

Background

Eating can be a significant challenge for cancer survivors; however, to date there is no systematic way of assessing and addressing food related quality of life in this group. The purpose of our study was to develop a framework for doing so.

Methods

Over the course of 6 years in participant-led food workshops, we worked alongside 25 head and neck cancer (HNC) survivors and their partners, employing video-reflexive ethnographic (VRE) methods. The current study reports on data from the two summative workshops of this series where we worked with participants to cohere the emergent themes. Video and transcripts were reviewed and coded with participants and stakeholders according to domains of life that were affected by food. Three of the authors, one of whom is both survivor and researcher, arrived at the consensus framework.

Results

Seven areas of life were identified as affecting, or being affected by, altered eating. Three were physiological: anatomical, functional and sensory. Two captured the cognitive and behavioural labour of eating. Social life and identity were altered. The foregoing had an enduring emotional impact.

Conclusions

Altered eating has physical, emotional and social consequences. The altered eating framework provides a systematic way of exploring those consequences with individual survivors. This framework has the potential to improve both the assessment and treatment of altered eating, to benefit food-related quality of life.

Validating data analysis of broadband laser ranging

Broadband laser ranging combines spectral interferometry and a dispersive Fourier transform to achieve high-repetition-rate measurements of the position of a moving surface. Telecommunications fiber is a convenient tool for generating the large linear dispersions required for a dispersive Fourier transform, but standard fiber also has higher-order dispersion that distorts the Fourier transform. Imperfections in the dispersive Fourier transform significantly complicate the ranging signal and must be dealt with to make high-precision measurements. We describe in detail an analysis process for interpreting ranging data when standard telecommunications fiber is used to perform an imperfect dispersive Fourier transform. This analysis process is experimentally validated over a 27-cm scan of static positions, showing an accuracy of 50 μm and a root-mean-square precision of 4.7 μm.

Relationship between [123 I]-FP-CIT SPECT and clinical progression in Parkinson's disease

BACKGROUND

The demonstration of presynaptic dopaminergic deficiency on [¹²³ I]-FP-CIT SPECT imaging is a useful ancillary tool in the diagnosis of Parkinson's disease (PD). Whilst there is evidence of a cross-sectional relationship between the degree of dopaminergic deficiency and severity of bradykinesia and rigidity, longitudinal studies are rare. Moreover, the relationship between motor subtypes and their dopaminergic deficient state is not well characterized.

AIM

Our primary aim was to assess the correlations between dopaminergic deficiency on baseline [¹²³ I]-FP-CIT SPECT imaging with the progression of motor severity in patients classified by motor subtype, and the development of motor complications. Our secondary aim was to assess the correlation between UPDRS-III subscores and the time to onset of motor complications.

METHODS

42 PD patients with abnormal baseline [¹²³ I]-FP-CIT SPECT scans and at least 3 years of clinical follow-up were classified by motor subtype: akinetic-rigid, tremor-dominant or mixed. UPDRS-III scores at baseline and at 3-year follow-up, and time to onset of motor complications were recorded.

RESULTS

[¹²³ I]-FP-CIT uptake ratios were inversely correlated with UPDRS-III scores at 3 years only in akinetic-rigid patients (r=-.51, P=.04). Time to onset of motor complications was inversely correlated with UPDRS-III subscores for bradykinesia and rigidity at baseline (r=-.52, P=.02) and at 3 years (r=-.54, P=.01).

CONCLUSION

The degree of dopaminergic deficiency on baseline [¹²³ I]-FP-CIT SPECT inversely correlates with motor severity at 3-year follow-up in akinetic-rigid patients only. Furthermore, UPDRS-III subscores for bradykinesia and rigidity at baseline show an inverse correlation with time to onset of motor complications across all PD subtypes.

Report of an independent peer review of an acrylonitrile risk assessment

A peer review panel made up of experts in toxicology, epidemiology, cancer mode of action (MOA), cancer mechanisms, carcinogenicity, genotoxicity, dose–response, US Environmental Protection Agency (EPA) cancer and noncancer methods, pharmacokinetic modeling and acrylonitrile, met on 22–23 September 2003 in Cincinnati, OH. The purpose of the meeting was to provide an independent review of a risk assessment of acrylonitrile that had been prepared by the Acrylonitrile Group (AN Group). Toxicology Excellence for Risk Assessment (TERA) organized the peer review and selected the panel. The panel discussed the toxicity and epidemiology literature of acrylonitrile and MOA information, and reached conclusions regarding its MOA, weight of evidence (WOE) for carcinogenicity, preferred approach for dose-response assessment and risk values. This paper summarizes the discussion and conclusions of the panel regarding the acrylonitrile assessment. Subsequent to the peer review, the authors of the acrylonitrile assessment revised their report and the panel reviewed the revised report. A manuscript of the revised assessment is being published in Regulatory Toxicology and Pharmacology.

Comparing the Performance Status Scale and MD Anderson Dysphagia Inventory as swallowing outcome measures in head and neck cancer: a prospective cohort study

OBJECTIVES

To examine the relationship between the two disease-specific measures currently in use to assess swallowing outcomes following treatment in patients with head and neck cancer: the Performance Status Scale (PSS) and MD Anderson Dysphagia Inventory (MDADI).

DESIGN

A prospective cohort study.

SETTING

Four head and neck cancer multidisciplinary clinics in the North of England Cancer Network.

PARTICIPANTS

114 patients with cancers of the upper aerodigestive tract.

MAIN OUTCOME MEASURE

Measures of swallowing function administered prospectively across 4 timepoints

RESULTS

Spearman's correlation coefficients were used to measure the relationship between the two scales. There was statistically significant correlation between the two tools at pre-treatment (rs = 0.428, P < 0.000), 3 months post-treatment (rs = 0.454, P < 0.002), 6 months post-treatment (rs = 0.551, P < 0.000) and 12 months post-treatment (rs = 0.680, P < 0.000).

CONCLUSION

This is the first prospective study comparing the MDADI and PSS questionnaires at multiple time points. Our study shows that these different instruments have a good relationship in measuring swallowing function in patients with head and neck cancer in short and medium term after treatment.

Are staffing shortages changing the culture of midwifery?

The effects of budgetary changes on midwives' practice environment have raised concerns in many settings. A survey of midwives and student midwives in the UK and Republic of Ireland in 2014 produced 280 responses. Staffing shortages were regarded as underpinning many changes, one of which was that of previously optional 'extra' activities, such as unpaid overtime, becoming mandatory. Shortages were aggravated in less acute areas by the transfer of midwives to more acute settings. One of the fears expressed by midwives was that a permanent change in the culture of midwifery would result. These phenomena are the everyday experiences of practising midwives, but they have failed to be addressed in the documents published by regulatory and review bodies.

One-year swallowing outcomes following transoral laser microsurgery +/- adjuvant therapy versus primary chemoradiotherapy for advanced stage oropharyngeal squamous cell carcinoma

OBJECTIVES

To assess the between-group change in swallowing function from baseline to 12 months following treatment, for patients treated for resectable stage III and IVA oropharyngeal squamous cell carcinoma. To assess the within-group change in swallowing function between 3 and 12 months following treatment.

DESIGN

Non-randomised cohort study.

SETTING

A single head and neck cancer unit with oncology services held at the nearby regional treatment centre.

PARTICIPANTS

Twenty-five patients treated with Transoral Laser Microsurgery +/- adjuvant (chemo)radiotherapy (Transoral Laser Microsurgery) observed alongside an historic cohort of 33 patients treated with (chemo)radiotherapy.

MAIN OUTCOME MEASURES

The patient reported MD Anderson Dysphagia Inventory (MDADI), an objective timed Water Swallow Test, and the clinician rated normalcy of diet subsection of the Performance of Swallowing Scale .

RESULTS

Between baseline and 12 months, patients treated with primary (chemo)radiotherapy demonstrated greater deterioration in swallowing function compared to Transoral Laser Microsurgery for all 3 swallowing measures. Between 3 and 12 months, the only significant change was an improvement in Performance of Swallowing Scale scores in the (chemo)radiotherapy group.

CONCLUSIONS

This is the first study to report the results of a complimentary set of swallowing measures for patients treated with Transoral Laser Microsurgery, observed alongside a cohort of (chemo)radiotherapy patients. The preliminary results suggest a benefit in swallowing function for Transoral Laser Microsurgery over (chemo)radiotherapy during the year following treatment.

Integrating asthma hazard characterization methods for consumer products

Despite extensive study, definitive conclusions regarding the relationship between asthma and consumer products remain elusive. Uncertainties reflect the multi-faceted nature of asthma (i.e., contributions of immunologic and non-immunologic mechanisms). Many substances used in consumer products are associated with occupational asthma or asthma-like syndromes. However, risk assessment methods do not adequately predict the potential for consumer product exposures to trigger asthma and related syndromes under lower-level end-user conditions. A decision tree system is required to characterize asthma and respiratory-related hazards associated with consumer products. A system can be built to incorporate the best features of existing guidance, frameworks, and models using a weight-of-evidence (WoE) approach. With this goal in mind, we have evaluated chemical hazard characterization methods for asthma and asthma-like responses. Despite the wealth of information available, current hazard characterization methods do not definitively identify whether a particular ingredient will cause or exacerbate asthma, asthma-like responses, or sensitization of the respiratory tract at lower levels associated with consumer product use. Effective use of hierarchical lines of evidence relies on consideration of the relevance and potency of assays, organization of assays by mode of action, and better assay validation. It is anticipated that the analysis of existing methods will support the development of a refined WoE approach.

Baseline [(123) I]FP-CIT SPECT (DaTSCAN) severity correlates with medication use at 3 years in Parkinson's disease

BACKGROUND

Presynaptic dopaminergic deficiency on dopamine transporter imaging supports a clinical diagnosis of Parkinson's disease and correlates with the severity of rigidity and bradykinesia. Baseline dopaminergic deficiency predicts clinical severity, but the relationship with subsequent medication use has not been reported.

METHODS

A randomly selected cross section of 83 Parkinson's disease (PD) patients who had [(123) I] FP-CIT SPECT at the time of clinical diagnosis was identified. Dopaminergic deficiency was graded 1, 2 or 3 with increasing severity using visual assessment and by semiquantitative analysis of putamen and caudate uptake. Antiparkinson medication usage and clinical severity by Hoehn and Yahr were noted annually to 3 years.

RESULTS

In 83 patients (66% male, median age 65.0 years, IQ 55.4-71.8), [(123) I]FP-CIT SPECT was grade 1 in 20 (24%), grade 2 in 53 (64%) and grade 3 in 10 patients (12%). Dopamine transporter uptake ratios were inversely associated with antiparkinson medication usage (r = -0.26, P = 0.0201) and Hoehn Yahr stage (r = -0.32, P = 0.0029) at 3 years from baseline, but there was considerable variation in drug usage in individual patients. At 3 years, patients with grade 1 scans at baseline received a median dose of 325 levodopa equivalent units (LEU) (interquartile range 175-433); grade 2 scan patients 400 LEU (interquartile range 300-635); and grade 3 scan patients 460 LEU (interquartile range 252-658).

CONCLUSION

The degree of reduction in presynaptic dopaminergic uptake at baseline is associated with higher antiparkinson drug dosage at follow-up, but the wide variation means that the baseline FP-CIT SPECT does not reliably predict drug use in individual cases.

The politics of maternity

Changes in the culture of health care require that, to be effective, midwifery practice should become more woman-centred. This may be facilitated by adopting a stronger community orientation. In this way the hegemony of maternity care may be addressed. This paper seeks to draw readers' attention to political developments and to inspire midwives to greater awareness and, possibly, activity.
