Because of restrictions on in-person research due to COVID-19, researchers are now relying on remotely recorded data to a much greater extent than in the past. Given the change in methodology, it is important to know how remote recording might affect acoustic measurements, either because of different recording devices used by participants and consultants or because of the software used to make recordings. This study investigates audio signal fidelity across different inperson recording equipment and remote recording software when compared to solid-state digital audio. We show that equipment choice and software can have a large effect on acoustic measurements, including those of frequency, duration, and noise. The issues do not just reflect decreased reliability; some measurements are systematically shifted in particular recording conditions. These results show the importance of carefully considering and documenting equipment choices, particularly for crosslinguistic or cross-speaker comparisons. We close with a framework for researchers to use in deciding what types of recording may be most appropriate.
This article considers two instances of rapidly accelerating linguistic change in Glaswegian vernacular, th-fronting and l-vocalization, both typically associated with the Cockney dialect of London. Both changes have been underway for some time, but took off during the 1990s. In this article we consider a range of factors that are contributing to the rapid proliferation of these forms in the speech of inner-city Glaswegian adolescents. Our multivariate analysis shows very strong effects for linguistic factors, as well as strong positive correlations with social practices relating to local Glaswegian street style, some links with dialect contact with friends and family living in England, and—perhaps surprisingly—also positive correlations with strong psychological engagement with the London-based TV soap drama EastEnders. Our results suggest that the changes are being propelled by several processes: ongoing transmission and at the same time continuing diffusion through dialect contact; the local social meanings carried by these variants for these speakers; and strong engagement with a favorite TV drama. For this community at least, engaging with a favorite TV drama is an additional accelerating factor in rapid linguistic diffusion.
The first year of life is a critical period when nutrient intakes can affect long-term health outcomes. Although household food insecurity may result in inadequate nutrient intakes or a higher risk of obesity, no studies have comprehensively assessed nutrient intakes of infants from food insecure households. This study aimed to investigate how infant nutrient intakes and BMI differ by household food security.
Design:
Cross-sectional analysis of the First Foods New Zealand study of infants aged 7–10 months. Two 24-h diet recalls assessed nutrient intakes. ‘Usual’ intakes were calculated using the multiple source method. BMI z-scores were calculated using WHO Child Growth Standards.
Setting:
Dunedin and Auckland, New Zealand.
Participants:
Households with infants (n 604) classified as: severely food insecure, moderately food insecure or food secure.
Results:
Nutrient intakes of food insecure and food secure infants were similar, aside from slightly higher free and added sugars intakes in food insecure infants. Energy intakes were adequate, and intakes of most nutrients investigated were likely to be adequate. Severely food insecure infants had a higher mean BMI z-score than food secure infants, although no significant differences in weight categories (underweight, healthy weight and overweight) were observed between groups.
Conclusions:
Household food insecurity, in the short term, does not appear to adversely impact the nutrient intakes and weight status of infants. However, mothers may be protecting their infants from potential nutritional impacts of food insecurity. Future research should investigate how food insecurity affects nutrient intakes of the entire household.
The 58th Annual Scientific Conference of the Nutrition Society of New Zealand, held in Christchurch in 2024, brought together 187 delegates under the theme ‘Kotahitanga: Bridging Research, Industry and Practice’. This theme reflected the society’s commitment to uniting diverse sectors to address key nutrition challenges across the life course. Kotahitanga refers to unity and collective action. Topics included nutrition in ageing and chronic disease, infant and toddler nutrition, gut health, sustainable food systems and food safety. Presentations on sarcopenia and Parkinson’s disease emphasised the need for greater awareness and tailored nutrition strategies for older adults. The Muriel Bell Lecture celebrated the legacy of New Zealand’s first State Nutritionist and called for continued leadership in evidence-based nutrition and encouraged nutritionists to communicate research to the public. A panel on science communication offered practical strategies for engaging the public and countering misinformation. The conference reinforced the importance of collaboration, advocacy and practical application in advancing nutrition.
Cystic neck masses have a wide differential diagnosis. Fine-needle aspiration cytology with or without thyroglobulin washout may be non-diagnostic or false-negative, while a primary thyroid tumour may be sonographically occult. We aim to demonstrate the value of biochemical thyroglobulin measurement in directly aspirated cyst fluid in diagnosis or exclusion of papillary thyroid cancer cystic nodal metastases.
Methods
Prospective case series (n = 10) of patients presenting with a lateral cystic neck mass with or without thyroid abnormality, where thyroglobulin measurement of aspirated cyst fluid was part of the diagnostic workup.
Results
N1b papillary thyroid cancer diagnosis was predicted by elevated thyroglobulin in cyst fluid aspirate in seven cases, all greater than 200 µg/L, confirmed at surgical resection. Papillary thyroid cancer nodal metastasis was refuted by low thyroglobulin result in three benign cystic lesions, all less than 6 µg/L.
Conclusion
Biochemical thyroglobulin analysis of fluid aspirate is a valuable adjunct for evaluation of cystic neck masses and pre-operative diagnosis of papillary thyroid cancer cystic nodal metastases.
Understanding how different symptoms co-occur and are correlated may provide insights into the pathophysiology of disease. The lack of group-to-individual generalizability of co-occurrence of symptoms was recently demonstrated by comparing intra-individual and inter-individual correlations in several psychological studies. Here, we investigate this phenomenon for lower urinary tract symptoms (LUTS).
Methods:
We analyzed data collected in the Symptoms of Lower Urinary Tract Dysfunction Research Network Recall Study. Participants responded to questions about their urinary symptoms for 25 consecutive days. These questions queried urologic symptoms including storage (urinary urgency, frequency, nocturia, and urinary incontinence), voiding (slow/weak stream), and post-micturition (incomplete emptying and post-micturition dribble) symptoms. We calculated Pearson correlation coefficients and cosine similarity measures and compared distributions of intra-individual and inter-individual (cohort) metrics.
Results:
Among 234 participants, distributions of intra-individual measures were 10-fold wider than those of inter-individual correlations. There are pairs of questions with distributions of correlations and cosine similarities containing individuals with extreme positive (>0.8) and extreme negative values (<–0.8). There are groups of participants with strong positive and negative correlations of urinary frequency and nocturia, urinary incontinence and weak flow, as well as strong negative and positive correlations of urinary frequency and dribbling. Information on these extreme groups is averaged out and lost in the inter-individual correlations.
Conclusions:
Lack of group-to-individual generalizability previously shown for psychological symptoms is confirmed for LUTS. Wealth of information on the co-occurrence and co-evolution of LUTS in the intra-individual correlations and cosine similarities corroborates heterogeneity of LUTS and can be useful for deep phenotyping and for identifying personalized treatments of LUTS.
Advance Choice Documents (ACDs) have been recommended for inclusion in new mental health legislation for England and Wales based on evidence they reduce compulsory psychiatric admission, with particular benefit for Black people. As Black people disproportionately experience compulsory psychiatric admission in the UK, our aim was to explore potential barriers and enablers to effective ACD implementation for Black people with previous experience of compulsory admission.
Methods:
Six stakeholder workshops and one consensus workshop were held with: Black service users who had previously been involuntarily admitted, carers/supporters of Black service users, and mental health staff. Thematic analysis was conducted on workshop transcripts.
Results:
Participants were service users (n = 13), carers/supporters (n = 7), service users and carers/supporters (n = 3), and staff (n = 18). Thematic analysis identified themes of ‘training’, ‘completion’, ‘access’, and ‘use’ concerning ACD implementation. Stakeholders highlighted the importance of understanding the racialised experience of Black service users for effective ACD implementation. Strong communication between and amongst stakeholders and helpful systems for access were also emphasised. Stakeholders also recommended joint training and independent facilitation of ACDs to address Black service user-staff power imbalances.
Conclusions:
Known enablers and barriers to ACD implementation are important when considering ACDs for Black people, as is explicitly engaging with their experiences holistically, including racialised historical and individual experiences that underline some treatment preferences. Independent facilitation and shifts in service user-staff power dynamics present as key to realising the potential of ACDs to empower Black service users in relation to their care, and in turn to potentially reduce coercive care.
One hundred percent pasture-fed beef production has been suggested as a promising approach for sustainable ruminant farming, due to the potential benefits that can accrue across a range of sustainability domains. This study aimed to investigate the impacts across the four domains of sustainability of a wholesale switch from conventional to 100% pasture-fed beef production in the UK. We used fuzzy cognitive mapping (FCM) as a method for extracting knowledge from multiple stakeholders to create representative systems models of both conventional and pasture-based beef production systems. We then conducted a scenario analysis to assess how a switch to a pasture-fed system could affect components of sustainability in the UK beef sector. The FCMs indicated that vegetation quality, grass use efficiency, and soil health were central components of the pasture-fed approach, while economic and regulatory aspects, and climate change targets were more central to mainstream production approaches. The most marked changes under the 100% conversion scenario were an increase in income from subsidies (27.3%) in line with ‘public money for public goods’, a decrease in ability to export beef (unless advice to reduce consumption of animal protein is followed) (23.5%), a decrease in land used for farming vs other uses (e.g., natural capital) (11.23%), and a decrease in the use of feed from agricultural co/byproducts (7.5%), freeing up these feed sources for more sustainable monogastric production. Therefore, the mapping and scenario analysis suggests that while upscaling the pasture-fed approach may reduce productivity, it would likely increase public goods provision and reduce feed–food competition in the UK.
Following a health technology assessment, the Health Service Executive (HSE) supported reimbursement of dupilumab subject to a managed access protocol (MAP) being implemented. Reimbursement is restricted to a subgroup of the fully licensed indication, that is, moderate-to-severe refractory atopic dermatitis (AD) in adults and adolescents 12 years and older. This study provides an overview of the first year of the MAP.
Methods
All reimbursement applications submitted to the HSE Medicines Management Programme between 1 April 2021 and 31 March 2022 were reviewed. Key demographic and clinical characteristics of the approved population were analyzed. Reimbursement claims data within the specified period were extracted from the HSE Primary Care Reimbursement Services national pharmacy claims database. All data were compiled and analyzed using SPSS Statistics 27. Expenditure estimates were based on wholesale prices and were exclusive of value-added tax, fees, and confidential rebates.
Results
During the study period, 382 applications were submitted, 96 percent (n=365) of which were approved. Among approved patients, the mean age was 35 years (range 12 to 79 years), the mean number of years between AD diagnosis and approval was 22.65 years (range 1 to 78 years), and 65 percent (n=238) were men. The mean Eczema Area and Severity Index score was 28.72 and the mean (Children’s) Dermatology Life Quality Index score was 19.72. Approved patients who had unsuccessfully tried other systemic immunosuppressants had trialed up to five different medicines (mean=1.6). Year one expenditure was EUR2.4million, with 70 percent of approved patients accessing treatment.
Conclusions
Most applications submitted through the MAP were approved. These patients met the predefined evidence-based eligibility criteria for treatment. Patient numbers were higher than estimated, suggesting that the MAP did not hinder access. Utilizing health technology management by way of a MAP has facilitated access to expensive medicines for patients with the greatest need, while controlling expenditure for the payer.
The calcitonin gene-related peptide monoclonal antibodies (CGRP MABs) erenumab, fremanezumab, and galcanezumab are reimbursed in Ireland under the High Tech Arrangement, subject to a managed access protocol (MAP), for the prophylaxis of chronic migraine in adults in whom three or more prophylactic treatments have failed. This study provides an overview of submitted reimbursement applications and the utilization of CGRP MABs.
Methods
The MAP for CGRP MABs was introduced on 1 September 2021 and is operated by the Health Service Executive (HSE) Medicines Management Programme. Individual patient reimbursement applications for CGRP MABs submitted through an online reimbursement application system between 1 September 2021 and 30 April 2023 were reviewed. Utilization data from 1 September 2021 to 30 April 2023 were extracted from the HSE Primary Care Reimbursement Service national pharmacy reimbursement claims database for the High Tech Arrangement. Analysis was performed using SAS® 9.4 software.
Results
A total of 1,517 reimbursement applications were submitted in the study period. Reimbursement was approved for 96.1 percent (n=1,458) of the applications. A total of 1,399 individual patients (mean age 45 years) were dispensed a CGRP MAB under the High Tech Arrangement between September 2021 and April 2023, the majority of whom were women (n=1,141). Almost 90 percent of patients were considered treatment adherent. In April 2023, the market share of the individual CGRP MABs on the High Tech Arrangement was 56 percent (n=599) for fremanezumab, 38.3 percent (n=409) for erenumab, and 5.7 percent (n=61) for galcanezumab.
Conclusions
MAPs are part of the health technology management approach to drug reimbursement in the Irish healthcare setting, ensuring that reimbursement is in line with approved subgroups of the licensed indication. Used in conjunction with health technology assessment, MAPs enable access to high-cost drug treatments for patients with the greatest unmet need, while providing budgetary oversight and certainty for the payer.
Increasingly in Ireland, there are specific criteria attached to reimbursement approval for new medicines. Health technology assessment (HTA) identifies where uncertainty is greatest in relation to clinical and cost-effectiveness evidence and budget impact estimates; our health technology management (HTM) approach uses these outputs from HTA to design protocols to manage these uncertainties in the post-reimbursement phase.
Methods
A bespoke managed access protocol (MAP) is developed for each medicine reimbursed under this approach, informed by uncertainties highlighted in the HTA, directions from the decision-maker, and relevant particulars arising from commercial negotiations. Individual patient reimbursement applications are submitted via an online application system linked directly to the national pharmacy claims system. Pharmacists review the applications and approve reimbursement support where the patient meets the reimbursement criteria. The process is adaptive, allowing expansion of the criteria to include previously excluded patient cohorts, and the addition of new indications. It can also work across differing reimbursement arrangements (hospital/primary care).
Results
The MAP for liraglutide for weight management confines reimbursement to patients with a body mass index greater than or equal to 35 kg/m², prediabetes, and high risk for cardiovascular disease. Phase I reimbursement support lasts for six months; patients not attaining greater than or equal to five percent weight loss are deemed non-responders as per the HTA, and reimbursement support is discontinued. The MAP for dupilumab confined reimbursement support to adults with refractory moderate-to-severe atopic dermatitis, where cost-effectiveness was plausible in the HTA. The MAP for calcitonin-gene-related-peptides monoclonal antibodies confines reimbursement support to patients with chronic migraine, refractory to at least three prophylactic treatments, where cost-effectiveness was plausible in the HTA.
Conclusions
Across these MAPs, over 3,000 patients accessed novel treatments for chronic illnesses in September 2023. HTM provides an effective mechanism to facilitate access to high-cost medicines for targeted patient groups, while providing increased oversight and budgetary certainty. Key to acceptance is utilization of HTA outputs to implement evidence-based HTM measures targeting specific uncertainties as highlighted in the HTA report.
There is a high incidence of serious mental illness (SMI) and antipsychotic use in the respiratory high dependence unit (HDU) compared with the general population. However, there is a paucity of data in the extant literature evaluating the relationships between respiratory failure and antipsychotics.
Aims
To investigate the relationship between antipsychotics and respiratory failure in people admitted to a respiratory HDU, and to gain a better understanding of the potential impact of antipsychotic medications on respiratory outcomes.
Method
Medical, demographic and clinical outcome data were collected for a consecutive sample of 638 individuals admitted to a respiratory HDU between the dates 1 January 2018 and 29 May 2021 at a large quaternary hospital.
Results
Multivariate models controlling for confounders found that antipsychotic medications increased risk of admission for type 2 respiratory failure and chronic obstructive pulmonary disease exacerbation without hypercapnia by 3.7 and 11.45 times, respectively. For people admitted with type 2 respiratory failure, antipsychotic use increased the risk of requiring non-invasive ventilation by 4.9 times. Those prescribed an antipsychotic were more likely to be readmitted within 30 days. Over 30% of individuals were prescribed antipsychotics for an unlicensed indication.
Conclusions
Poor respiratory outcomes may be a previously unknown adverse drug reaction of antipsychotics. Modifications to clinical care and clinical pathways for those with SMI prescribed antipsychotic medications, including optimising their chronic health and deprescribing where appropriate, should be prioritised.
Background: Black, Asian and Minority Ethnic (BAME) people continue to present later to specialist care centres and services for memory problems. This poses significant concerns due to implications for poorer treatment outcomes and higher treatment cost among this population. While diverse interventions to support improved help seeking for dementia have been proffered for other BAME communities, there is a paucity of research involving the Black African and Caribbean community. Furthermore, whilst community health professionals like the doctors and community nurses have been involved in such interventions, no previous research has considered the role of the community pharmacist. This research explored opportunities for community pharmacists to support improved help seeking for dementia among the Black African and Caribbean population.
Methods: This research was a multi-stage project involving surveys and interviews with community pharmacists and Black Africans and Caribbeans as participants.
Results: Knowledge, attitude and beliefs around dementia and it’s causes appeared to be major barriers to help seeking among the Black African and Caribbean population. For example, beliefs that dementia is caused by ‘the spirits’ and dementia is a repercussion for past wrongdoing and therefore not amenable to medical intervention. The community pharmacists believe they are well positioned to spot initial signs of dementia among their clients and are therefore willing to offer help seeking support to this population.
Conclusions: To offer intervention for timely help-seeking for dementia, a culturally tailored dementia education for the Black African and Caribbean population should be considered. In addition, training on the impact of cultural beliefs on help seeking for dementia should be considered for the communitypharmacists.
Oceania is currently facing a substantial challenge: to provide sustainable and ethical food systems that support nutrition and health across land and water. The Nutrition Society of Australia and the Nutrition Society of New Zealand held a joint 2023 Annual Scientific Meeting on ‘Nutrition and Wellbeing in Oceania’ attended by 408 delegates. This was a timely conference focussing on nutrition challenges across the Pacific, emphasising the importance of nutrition across land and water, education settings, women’s health and gut health. Cutting-edge, multi-disciplinary and collaborative research was presented in a 4-day programme of keynote presentations, workshops, oral and poster sessions, breakfast and lunch symposiums and early career researcher sessions. The conference highlighted the importance of collaboration between nations to address the challenge facing nutrition and wellbeing across Oceania. A systems approach of collaboration among scientists, industry and government is vital for finding solutions to this challenge.
Candida auris is an emerging fungal pathogen increasingly recognized as a cause of healthcare-associated infections including outbreaks.
Methods:
We performed a mixed-methods study to characterize the emergence of C. auris in the state of Maryland from 2019 to 2022, with a focus on socioeconomic vulnerability and infection prevention opportunities. We describe all case-patients of C. auris among Maryland residents from June 2019 to December 2021 detected by Maryland Department of Health. We compared neighborhood socioeconomic characteristics of skilled nursing facilities (SNFs) with and without C. auris transmission outbreaks using both the social vulnerability index (SVI) and the area deprivation index (ADI). The SVI and the ADI were obtained at the state level, with an SVI ≥ 75th percentile or an ADI ≥ 80th percentile considered severely disadvantaged. We summarized infection control assessments at SNFs with outbreaks using a qualitative analysis.
Results:
A total of 140 individuals tested positive for C. auris in the study period in Maryland; 46 (33%) had a positive clinical culture. Sixty (43%) were associated with a SNF, 37 (26%) were ventilated, and 87 (62%) had a documented wound. Separate facility-level neighborhood analysis showed SNFs with likely C. auris transmission were disproportionately located in neighborhoods in the top quartile of deprivation by the SVI, characterized by low socioeconomic status and high proportion of racial/ethnic minorities. Multiple infection control deficiencies were noted at these SNFs.
Conclusion:
Neighborhood socioeconomic vulnerability may contribute to the emergence and transmission of C. auris in a community.
Childhood adversity is associated with increased later mental health problems and suicidal behaviour. Opportunities for earlier healthcare identification and intervention are needed.
Aim
To determine associations between hospital admissions for childhood adversity and mental health in children who later die by suicide.
Method
Population-based longitudinal case-control study. Scottish in-patient general and psychiatric records were summarised for individuals born 1981 or later who died by suicide between 1991 and 2017 (cases), and matched controls (1:10), for childhood adversity and mental health (broadly defined as psychiatric diagnoses and general hospital admissions for self-harm and substance use).
Results
Records were extracted for 2477 ‘cases’ and 24 777 ‘controls’; 2106 cases (85%) and 13 589 controls (55%) had lifespan hospitalisations. Mean age at death was 23.7; 75.9% were male. Maltreatment or violence-related childhood adversity codes were recorded for 7.6% cases aged 10–17 (160/2106) versus 2.7% controls (371/13 589), odds ratio = 2.9 (95% CI, 2.4–3.6); mental health-related admissions were recorded for 21.7% cases (458/2106), versus 4.1% controls (560/13 589), odds ratio = 6.5 (95% CI, 5.7–7.4); 80% of mental health admissions were in general hospitals. Using conditional logistic models, we found a dose-response effect of mental health admissions <18y, with highest adjusted odds ratio (aOR) for three or more mental health admissions: aORmale = 8.17 (95% CI, 5.02–13.29), aORfemale = 15.08 (95% CI, 8.07–28.17). We estimated that each type of childhood adversity multiplied odds of suicide by aORmale = 1.90 (95% CI, 1.64–2.21), aORfemale = 2.65 (95% CI, 1.94–3.62), and each mental health admission by aORmale = 2.06 (95% CI, 1.81–2.34), aORfemale = 1.78 (95% CI, 1.50–2.10).
Conclusions
Our lifespan study found that experiencing childhood adversity (primarily maltreatment or violence-related admissions) or mental health admissions increased odds of young person suicide, with highest odds for those experiencing both. Healthcare practitioners should identify and flag potential ‘at-risk’ adolescents to prevent future suicidal acts, especially those in general hospitals.
People with mental disorders have worse physical health compared with the general population, which could be attributable to receiving poorer quality healthcare.
Aims
To examine the relationship between severe and common mental disorders and risk of emergency hospital admissions for ambulatory care sensitive conditions (ACSCs), and factors associated with increased risk.
Method
Baseline data for England (N = 445 814) were taken from UK Biobank, which recruited participants aged 37–73 years during 2006–2010, and linked to hospital admission records up to 31 December 2019. Participants were grouped into those with a history of either schizophrenia, bipolar disorder, depression or anxiety, or no mental disorder. Survival analysis was used to assess the risk of hospital admission for ACSCs among those with mental disorders compared with those without, adjusting for factors in different domains (sociodemographic, socioeconomic, health and biomarkers, health-related behaviours, social isolation and psychological).
Results
People with schizophrenia had the highest (unadjusted) risk of hospital admission for ACSCs compared with those with no mental disorder (hazard ratio 4.40, 95% CI 4.04–4.80). People with bipolar disorder (hazard ratio 2.48, 95% CI 2.28–2.69) and depression or anxiety (hazard ratio 1.76, 95% CI 1.73–1.80) also had higher risk. Associations were more conservative when including all admissions, as opposed to first admissions only. The observed associations persisted after adjusting for a range of factors.
Conclusions
People with severe mental disorders have the highest risk of preventable hospital admissions. Ensuring people with mental disorders receive adequate ambulatory care is essential to reduce the large health inequalities they experience.
OBJECTIVES/GOALS: Microtubule poisons, like Taxol, are used to treat triple negative breast cancer (TNBC) and may induce lethal aneuploidy in cancer cells. Patients initially respond, but often develop drug resistance. New targeted drugs that cause aneuploidy may be a valuable approach to therapy. One potential target is the Kinesin 13 MCAK, which limits aneuploidy. METHODS/STUDY POPULATION: TCGA and GSE47561 databases were probed for MCAK expression, and data was stratified by subtype and survival statistics. Knockdown studies were performed to test whether MCAK knockdown sensitizes cells to taxanes for cell proliferation and for induction of aneuploidy. FRET and image-based screens were used to identify MCAK inhibitors from small molecule inhibitor libraries. Inhibitors were then tested for functional effects in multiple cell-based assays and for clonal growth in colony formation assays. RESULTS/ANTICIPATED RESULTS: MCAK expression is upregulated in TNBC and associated with reduced overall survival. Knockdown of MCAK caused a two-to-five-fold reduction of the IC50 for Taxol in cancer cell lines, with no change in normal cell lines. Taxol treatment or MCAK knockdown increased aneuploidy induction, with no additive effect between the two. Our small molecule screen identified three putative MCAK inhibitors, which induced aneuploidy in both taxane-sensitive and taxane-resistant cells. These inhibitors also reduced clonogenic growth, and the most potent inhibitor, C4, caused an approximate five-fold reduction in the IC50 for Taxol in cell proliferation assays. DISCUSSION/SIGNIFICANCE: MCAK can serve as a biomarker of breast cancer prognosis. MCAK knockdown or inhibition sensitizes cancer cells to Taxol without affecting normal cells, making it a potential target in combination therapy. MCAK inhibitors also reduce growth as single agents in taxane resistant lines, giving them potential use as therapies in resistant disease.
