Purpose

Pregnancy and the postpartum period are increasingly recognised as sensitive windows for cardiometabolic disease risk. Growing evidence suggests environmental exposures, including endocrine-disrupting chemicals (EDCs), are associated with an increased risk of pregnancy complications that are associated with long-term cardiometabolic risk. However, the impact of perinatal EDC exposure on subsequent cardiometabolic risk post-pregnancy is less understood. The Environmental Reproductive and Glucose Outcomes (ERGO) Study was established to investigate the associations of environmental exposures during the perinatal period with post-pregnancy parental cardiometabolic health.

Participants

Pregnant individuals aged ≥18 years without pre-existing diabetes were recruited at

Findings to date

We enrolled 653 unique pregnancies and retained 633 through delivery. Participants had a mean age of 33 years, 10% (n=61) developed gestational diabetes and 8% (n=50) developed pre-eclampsia. Participant pregnancy and postpartum urinary phthalate metabolite concentrations and postpartum glycaemic biomarkers were quantified. To date, studies within ERGO found higher exposure to phthalates and phthalate mixtures, and separately, higher exposure to radioactive ambient particulate matter, were associated with adverse gestational glycaemic outcomes. Additionally, certain personal care products used in pregnancy, notably hair oils, were associated with higher urinary phthalate metabolite concentrations, earlier gestational age at delivery and lower birth weight.

Future plans

Future work will leverage the longitudinal data collected on pregnancy and cardiometabolic outcomes, environmental exposures, questionnaires, banked biospecimens and paediatric data within the ERGO Study.

Temporal trends of ambulance time intervals for suspected stroke/transient ischaemic attack (TIA) before and during the COVID-19 pandemic in Ireland: a quasi-experimental study

Por: Burton · E. · Quinn · R. · Crosbie-Staunton · K. · Deasy · C. · Masterson · S. · O'Donnell · C. · Merwick · A. · Willis · D. · Kearney · P. M. · Mc Carthy · V. J. C. · Buckley · C. M.
Objectives

Time is a fundamental component of acute stroke and transient ischaemic attack (TIA) care, thus minimising prehospital delays is a crucial part of the stroke chain of survival. COVID-19 restrictions were introduced in Ireland in response to the pandemic, which resulted in major societal changes. However, current research on the effects of the COVID-19 pandemic on prehospital care for stroke/TIA is limited to early COVID-19 waves. Thus, we aimed to investigate the effect of the COVID-19 pandemic on ambulance time intervals and suspected stroke/TIA call volume for adults with suspected stroke and TIA in Ireland, from 2018 to 2021.

Design

We conducted a secondary data analysis with a quasi-experimental design.

Setting

We used data from the National Ambulance Service in Ireland. We defined the COVID-19 period as ‘1 March 2020–31 December 2021’ and the pre-COVID-19 period ‘1 January 2018–29 February 2020’.

Primary and secondary outcome measures

We compared five ambulance time intervals: ‘allocation performance’, ‘mobilisation performance’, ‘response time’, ‘on scene time’ and ‘conveyance time’ between the two periods using descriptive and regression analyses. We also compared call volume for suspected stroke/TIA between the pre-COVID-19 and COVID-19 periods using interrupted time series analysis.

Participants

We included all suspected stroke/TIA cases ≥18 years who called the National Ambulance Service from 2018 to 2021.

Results

40 004 cases were included: 19 826 in the pre-COVID-19 period and 19 731 in the COVID-19 period. All ambulance time intervals increased during the pandemic period compared with pre-COVID-19 (p

Conclusions

A ’shock' like a pandemic has a negative impact on the prehospital phase of care for time-sensitive conditions like stroke/TIA. System evaluation and public awareness campaigns are required to ensure maintenance of prehospital stroke pathways amidst future healthcare crises. Thus, this research is relevant to routine and extraordinary prehospital service planning.

The incredible shrinking puffin: Decreasing size and increasing proportional bill size of Atlantic puffins nesting at Machias Seal Island

by Heather L. Major, Joy E. Rivers, Quinn B. Carvey, Antony W. Diamond

Climate change imposes physiological constraints on organisms particularly through changing thermoregulatory requirements. Bergmann’s and Allen’s rules suggest that body size and the size of thermoregulatory structures differ between warm and cold locations, where body size decreases with temperature and thermoregulatory structures increase. However, phenotypic plastic responses to malnutrition during development can result in the same patterns while lacking fitness benefits. The Gulf of Maine (GOM), located at the southern end of the Labrador current, is warming faster than most of the world’s oceans, and many of the marine species that occupy these waters exist at the southern edge of their distributions including Atlantic puffins (Fratercula arctica; hereafter “puffin”). Monitoring of puffins in the GOM, at Machias Seal Island (MSI), has continued annually since 1995. We asked whether changes in adult puffin body size and the proportional size of bill to body have changed with observed rapid ocean warming. We found that the size of fledgling puffins is negatively related to sea surface temperature anomalies (warm conditions = small fledgers), adult puffin size is related to fledgling size (small fledgers = small adults), and adult puffins have decreased in size in recent years in response to malnutrition during development. We found an increase in the proportional size of bill to wing chord, likely in response to some mix of malnutrition during development and increasing air temperatures. Although studies have assessed clinal variation in seabird morphology with temperature, this is the first study addressing changes in seabird morphology in relation to ocean warming. Our results suggest that puffins nesting in the GOM have morphological plasticity that may help them acclimate to ocean warming.

Occupational physical activity as a determinant of daytime activity patterns and pregnancy and infant health

by Alexis Thrower, Tyler Quinn, Melissa Jones, Kara M. Whitaker, Bethany Barone Gibbs

Though physical activity (PA) is recommended during pregnancy, it remains unclear how occupational physical activity (OPA) and sedentary behavior (SB) contribute to activity patterns and health during pregnancy. The purpose of this secondary analysis was to determine if OPA pattern is a determinant of all-day PA and evaluate associations with pregnancy/infant health outcomes. Data was from two prospective cohorts with study visits each trimester: MoM Health (Pittsburgh, PA; n = 120) and PRAMS (Iowa City, Iowa; n = 20). Using employment status/job hours (self-reported in demographic questionnaires) and OPA from the Pregnancy Physical Activity Questionnaire, latent class analysis identified three groups: sitting (n = 61), part-time mixed (n = 9), and active (n = 29). A fourth group included non-working participants (n = 32). Device-based PA (ActiGraph GT3X), SB (activPAL3 micro), and blood pressure were measured each trimester. Glucose screening test, gestational age, gestational weight gain, adverse pregnancy outcomes (APOs: gestational hypertension, preeclampsia, eclampsia, gestational diabetes, intrauterine growth restriction, and preterm birth), and infant outcomes (length, weight, and sex) were abstracted from medical records. Associations between groups with APOs and pregnancy/infant health were calculated using linear/logistic regression with adjustment for age, pre-pregnancy BMI, education, and race. Self-reported participant characteristics were similar across groups, except education which was higher in the sitting versus other groups. All-day device-based PA differed across groups; for example, the sitting group had the highest SB across trimester (all p0.09). Compared to the non-working group, the risk of any APO was non-significantly higher in the sitting (OR = 2.27, 95%CI = 0.63–8.18) and active groups (OR = 2.40, 95%CI = 0.66–9.75), though not the part-time mixed (OR = 0.86, 95%CI = 0.08–9.1). OPA pattern is a determinant of all-day PA during pregnancy. Future studies with larger samples should examine associations between pregnancy OPA patterns and pregnancy/infant health.

Introduction

The Core Outcome Measures for Improving Care (COM-IC) project aims to deliver practical recommendations on the selection and implementation of a suite of core outcomes to measure the effectiveness of interventions for dementia care.

Methods and analysis

COM-IC embeds a participatory action approach to using the Alignment–Harmonisation–Results framework for measuring dementia care in Australia. Using this framework, suitable core outcome measures will be identified, analysed, implemented and audited. The methods for analysing each stage will be codesigned with stakeholders, through the conduit of a Stakeholder Reference Group including people living with dementia, formal and informal carers, aged care industry representatives, researchers, clinicians and policy actors. The codesigned evaluation methods consider two key factors: feasibility and acceptability. These considerations will be tested during a 6-month feasibility study embedded in aged care industry partner organisations.

Ethics and dissemination

COM-IC has received ethical approval from The University of Queensland (HREC 2021/HE001932). Results will be disseminated through networks established over the project, and in accordance with both the publication schedule and requests from the Stakeholder Reference Group. Full access to publications and reports will be made available through UQ eSpace (https://espace.library.uq.edu.au/), an open access repository hosted by The University of Queensland.

Frailty Assessment in Vascular OUtpatients Review (FAVOUR) protocol: single-centre prospective cohort study comparing feasibility and prognostic value of commonly used frailty assessment tools

Por: Welsh · S. A. · Hussey · K. · Brittenden · J. · Orr · D. J. · Quinn · T.
Introduction

Frailty has consistently demonstrated associations with poorer healthcare outcomes. Vascular guidelines have recognised the importance of frailty assessment. However, an abundance of frailty tools and a lack of prospective studies confirming suitability of routine frailty assessment in clinical practice has delayed the uptake of these guidelines. The Frailty Assessment in Vascular OUtpatients Review study speaks to this evidence gap. The primary aim is to assess feasibility of implementing routine frailty assessment in a reproducible outpatient setting. Secondary objectives include comparing prognostic values and interuser agreement across five frailty assessment tools.

Methods and analysis

This single-centre prospective cohort study of feasibility is conducted in a rapid-referral vascular surgery clinic, serving a population of 2 million. Adults with capacity (>18 years), attending a clinic for any reason, are eligible for inclusion. Five assessments are completed by patient (Rockwood Clinical Frailty Scale (CFS) and Frail NonDisabled Questionnaire), clinician (CFS, Healthcare Improvement Scotland FRAIL tool and ‘Initial Clinical Evaluation’) and researcher (11-item modified Frailty Index). Consistent with feasibility objectives, outcome measures include recruitment rates, frailty assessment completion rates, time-to-complete assessments and interuser variability. Electronic follow-up at 30 days and 1 year will assess home-time and mortality as prognostic indicators. Patients treated surgically/endovascularly will undergo additional 30-day and 1-year postoperative follow-up, outcome measures include: surgical procedure, mortality, complications (according to Clavien-Dindo Classification), length of stay, readmission rates, non-home discharge, home-time, higher social care requirements on discharge and amputation-free survival. Prognostic value will be compared by area under receiver operating characteristic curves. Continuous outcome variables will be analysed using Spearman’s rank correlation coefficient. Interuser agreement will be compared by percentage agreement in Cohen’s kappa coefficient.

Ethics and dissemination

The study is sponsored by National Health Service Greater Glasgow and Clyde (R&IUGN23CE014). London-Riverside REC (23/PR/0062) granted ethical approval. Results will be disseminated through publication in peer-reviewed vascular surgery and geriatric medicine themed journals and presentation at similar scientific conferences.

Introduction

Despite significant advances in managing acute stroke and reducing stroke mortality, preventing complications like post-stroke epilepsy (PSE) has seen limited progress. PSE research has been scattered worldwide with varying methodologies and data reporting. To address this, we established the International Post-stroke Epilepsy Research Consortium (IPSERC) to integrate global PSE research efforts. This protocol outlines an individual patient data meta-analysis (IPD-MA) to determine outcomes in patients with post-stroke seizures (PSS) and develop/validate PSE prediction models, comparing them with existing models. This protocol informs about creating the International Post-stroke Epilepsy Research Repository (IPSERR) to support future collaborative research.

Methods and analysis

We utilised a comprehensive search strategy and searched MEDLINE, Embase, PsycInfo, Cochrane, and Web of Science databases until 30 January 2023. We extracted observational studies of stroke patients aged ≥18 years, presenting early or late PSS with data on patient outcome measures, and conducted the risk of bias assessment. We did not apply any restriction based on the date or language of publication. We will invite these study authors and the IPSERC collaborators to contribute IPD to IPSERR. We will review the IPD lodged within IPSERR to identify patients who developed epileptic seizures and those who did not. We will merge the IPD files of individual data and standardise the variables where possible for consistency. We will conduct an IPD-MA to estimate the prognostic value of clinical characteristics in predicting PSE.

Ethics and dissemination

Ethics approval is not required for this study. The results will be published in peer-reviewed journals. This study will contribute to IPSERR, which will be available to researchers for future PSE research projects. It will also serve as a platform to anchor future clinical trials.

Investigation of social support as a mediator of the relationship between physical and psychological health among hospitalised patients

Abstract

Aim

To investigate the self-reported levels of social support from friends and family and from nurses as mediators of the relationship between self-rated physical and psychological condition in hospitalised patients.

Design

Cross-sectional study of adult inpatients at a large tertiary-care hospital in the northeast United States.

Methods

Multiple mediation analysis of survey data.

Results

In surveys received from 324 inpatients, one fourth of the variation in patients' self-rated psychological condition was explained by self-rated physical condition. Social support from family and friends mediated a significant proportion (11.0%) of the relationship between self-rated physical and psychological condition, however social support from nurses did not.

Conclusion

Social support from family and friends can positively influence the psychological health of inpatients, but nurses are not an adequate replacement for the social support provided by family and friends.

Implications for Nursing

Although nurses cannot replace the social support provided by family and friends, the assessment of social isolation and care planning of interventions to support patients is a fundamental nursing role. Technology to connect patients with friends and family should be used to mitigate isolation for hospitalised patients unable to receive in-person visits from loved ones.

Impact

The influence of social support from family and friends and nurses was addressed. The study found social support from family and friends, but not nurses, to influence the relationship between physical and psychological ratings. This finding has implications for the role of nurses in the hospital setting.

Reporting Method

Strengthening the Reporting of Observational Studies in Epidemiology guidelines were followed.
