RESUMEN

PURPOSE: There are several factors that negatively impact the well-being of those working in the screen industry. Consequently, the need to introduce Well-being Coordinators has been identified. This study explored the experiences of participants who undertook a Well-being Coordination course tailored for the screen sector. Additionally, it sought to delve into perspectives regarding well-being within the screen industry. METHODS: Semi-structured interviews were conducted. The study was guided by an interpretive descriptive approach. Reflexive thematic analysis was used to analyse data. FINDINGS: Five themes were identified: Opportunities and challenges working in the screen industry, co-existing with harassment, the need for change: importance of wellbeing, becoming a well-being co-ordinator: learning from the course, and the future of the well-being co-ordinator role: opportunities and challenges. The reality that cast and crew co-exist with several forms of harassment within the industry was noted. Despite this, there is hope for the future of the screen sector, particularly the positive impact the role of the Well-being Coordinator could have. CONCLUSIONS: The experiences of professionals across the screen industry vary; however, a pervasive culture of bullying and harassment is commonplace. Through the introduction of Well-being Coordinators, there is the potential to enact positive change.

RESUMEN

BACKGROUND & AIMS: The prevalence of precursor lesions for gastric cancer (GC) and the differential burden between countries of varying GC risk is not well-understood. We conducted a systematic review and meta-analysis to estimate the global prevalence of precursor lesions. METHODS: We estimated the prevalence of atrophic gastritis (AG), gastric intestinal metaplasia (IM), and dysplasia in regions with low, medium, and high GC incidence. Because IM is an advanced manifestation of AG, we assessed the prevalence of less advanced precursors, regardless of the presence of more advanced lesions. Prevalence was sub-stratified by Helicobacter pylori infection, symptomatology, and period (<2000, 2000-2010, and >2010). RESULTS: Among the 582 articles that underwent full-text review, 166 studies met inclusion criteria. The global prevalence estimates of AG, IM, and dysplasia were 25.4%, 16.2%, and 2.0%, respectively, on the basis of 126 studies that reported the prevalence of less advanced precursors, regardless of the presence of more advanced lesions. The prevalence of all precursor lesions was higher in high and medium compared with low GC incidence countries (P < .01). Prevalence of AG and IM was significantly higher among H pylori-infected individuals (P < .01) but not statistically different between symptomatic and asymptomatic individuals (P > .17). All precursors demonstrated a secular decrease in prevalence over time. CONCLUSIONS: Gastric precursor lesions have differences in prevalence in regions with differential GC incidence and are associated with H pylori infection. Because of the substantial prevalence of precursor lesions in both symptomatic and asymptomatic individuals, symptomatic evaluation may not be sufficient to identify individuals at risk. These estimates provide important insights for tailoring GC prevention strategies.

RESUMEN

Whey protein denaturation and aggregation have long been areas of research interest to the dairy industry, having significant implications for process performance and final product functionality and quality. As such, a significant number of analytical techniques have been developed or adapted to assess and characterize levels of whey protein denaturation and aggregation, to either maximize processing efficiency or create products with enhanced functionality (both technological and biological). This review aims to collate and critique these approaches based on their analytical principles and outline their application for the assessment of denaturation and aggregation. This review also provides insights into recent developments in process analytical technologies relating to whey protein denaturation and aggregation, whereby some of the analytical methods have been adapted to enable measurements in-line. Developments in this area will enable more live, in-process data to be generated, which will subsequently allow more adaptive processing, enabling improved product quality and processing efficiency. Along with the applicability of these techniques for the assessment of whey protein denaturation and aggregation, limitations are also presented to help assess the suitability of each analytical technique for specific areas of interest.

RESUMEN

The World Health Organisation states that more than 350 million people experience depression globally. The phenomenological changes in individuals experiencing depression are profound Phenomenological research can further researchers' and clinicians' understanding of this experience. This study aimed to gain a phenomenological understanding of how individuals with depression understood and made sense of their experiences. A methodology of interpretative phenomenological analysis was adopted. In-depth semi-structured interviews explored the lived experience of depression for eight individuals. Data were analysed into the superordinate theme Broken Self - Transforming the Self. The superordinate theme developed from the subordinate themes of 'unknown self, loss of self and one's identity', 'desperate for a way out', and thirdly, 'conflict with self and what's known', which related directly to how individuals made sense of their experience of depression. These research findings highlight the human implications of the experience of depression and the limitations of viewing depression from a biological or medical model lens. Understanding the human impact is essential for the effective, holistic practice of mental health nursing.

RESUMEN

In response to global challenges such as climate change and food insecurity, plant proteins have gained interest. Among these, lentils have emerged as a promising source of proteins due to their good nutritional profile and sustainability considerations. However, their widespread use in food products has been impeded by limited solubility. This study aimed to investigate the potential of high-shear mixing, a resource-efficient technique, to enhance lentil protein solubility and its functional properties. Red lentil protein isolate powders were rehydrated and subjected to a semi-continuous in-line high-shear treatment at 10,200 rpm for a timespan ranging from 0 to 15 min. The results highlighted a significant (p < 0.05) increase in solubility from 46.87 to 68.42% after 15 min of shearing and a reduction in particle size as a result of the intense shearing and disruption provided by the rotor and forced passage through the perforations of the stator. The volume-weighted mean diameter decreased from 5.13 to 1.72 µm after 15 min of shearing, also highlighted by the confocal micrographs which confirmed the breakdown of larger particles into smaller and more uniform particles. Rheological analysis indicated consistent Newtonian behaviour across all dispersions, with apparent viscosities ranging from 1.69 to 1.78 mPa.s. Surface hydrophobicity increased significantly (p < 0.05), from 830 to 1245, indicating exposure of otherwise buried hydrophobic groups. Furthermore, colloidal stability of the dispersion was improved, with separation rates decreasing from 71.23 to 24.16%·h-1. The significant enhancements in solubility, particle size reduction, and colloidal stability, highlight the potential of in-line high-shear mixing in improving the functional properties of lentil protein isolates for formulating sustainable food products with enhanced techno-functional properties.

RESUMEN

WHAT IS KNOWN ON THE SUBJECT?: Mental health recovery is acknowledged as a process of transformation and a way of living a meaningful life despite the presence of mental ill-health. Experiencing hope has been articulated as intrinsic to service users experience of a meaningful life. The social construction of mental illness and stigma are recognised as barriers to experiencing hope. Mental health professionals have responsibility to positively influence the experience of hope. WHAT THIS ARTICLE ADDS TO EXISTING KNOWLEDGE?: Individuals in mental health recovery experience hope as the embodiment of having a sense of possibility in life. Individuals' sense of possibility in life is underpinned by a belief and confidence that they will be ok. This belief is informed by 'feeling safe' and 'feeling connected'. This article generates an increased understanding of the dynamic relational processes that unpin hope generation. WHAT ARE THE IMPLICATIONS FOR MENTAL HEALTH NURSING PRACTICE?: Mental health stakeholders need to be more explicit in exploring 'hope' and uncovering its therapeutic potential. Mental health practitioners need skill in enabling individuals to feel safe and connected while understanding its role in cultivating hope. ABSTRACT: Introduction The experience of hope is widely acknowledged and empirically supported as a key catalyst of mental health recovery. Lived experience accounts of hope are critical in accessing data on what has been termed a nebulous concept. This article is the second presentation of data from this study and provides further context to improve understanding of hope and optimise its therapeutic potential. Aim To explore how individuals describe and make sense of their experience of hope in mental health recovery. Method A qualitative Interpretative Phenomenological Analysis (IPA) approach was used. Results This article explores the second of three experiential group themes: Hope as Having a sense of possibility 'I will be ok' which is informed by feeling safe and feeling connected. Discussion Having a sense of possibility is easier when basic needs are met and people feel connected to self, others and the universe. The use of creativity as a pathway to the imagination is positively experienced. The role of family, friends and healthcare professionals as hope reservoirs is critical. Finally, the framing of medication use emerged as significant. Implications for Practice It is important that all stakeholders appreciate the interpretation of hope and use the understanding and skill in harnessing its therapeutic potential.

RESUMEN

OBJECTIVES: This study aimed to assess whether recently proposed alternatives to the quality-adjusted life-year (QALY), intended to address concerns about discrimination, are suitable for informing resource allocation decisions. METHODS: We consider 2 alternatives to the QALY: the health years in total (HYT), recently proposed by Basu et al, and the equal value of life-years gained (evLYG), currently used by the Institute for Clinical and Economic Review. For completeness we also consider unweighted life-years (LYs). Using a hypothetical example comparing 3 mutually exclusive treatment options, we consider how calculations are performed under each approach and whether the resulting rankings are logically consistent. We also explore some further challenges that arise from the unique properties of the HYT approach. RESULTS: The HYT and evLYG approaches can result in logical inconsistencies that do not arise under the QALY or LY approaches. HYT can violate the independence of irrelevant alternatives axiom, whereas the evLYG can produce an unstable ranking of treatment options. HYT have additional issues, including an implausible assumption that the utilities associated with health-related quality of life and LYs are "separable," and a consideration of "counterfactual" health-related quality of life for patients who are dead. CONCLUSIONS: The HYT and evLYG approaches can result in logically inconsistent decisions. We recommend that decision makers avoid these approaches and that the logical consistency of any approaches proposed in future be thoroughly explored before considering their use in practice.

RESUMEN

BACKGROUND & AIMS: Nationwide organized gastric cancer (GC) screening programs have been running for decades in South Korea and Japan. This study conducted a quasi-experimental analysis to assess the population impact of these programs on GC mortality. METHODS: We used the flexible synthetic control method (SCM) to estimate the effect of the screening programs on age-standardized GC mortality and other upper gastrointestinal (UGI) diseases (esophageal cancer and peptic ulcer) among people aged ≥40 years. World Health Organization mortality data and country-level covariates from the World Bank and the Global Burden of Diseases study were used for the analyses. We compared postintervention trends in outcome with the counterfactual trend of the synthetic control and estimated average postintervention rate ratios (RRs) with associated 95% confidence intervals (CIs). A series of sensitivity analyses were conducted. RESULTS: The preintervention fits were acceptable for the analyses of South Korea and Japan's GC mortality but poor for Japan's other UGI disease mortality. The average postintervention RRs were 0.83 (95% CI, 0.71-0.96) for GC mortality and 0.72 (95% CI, 0.57-0.90) for other UGI disease mortality in South Korea. The RR reached 0.59 by the 15th year after the initiation of nationwide screening. For Japan, the average RRs were 0.97 (95% CI, 0.88-1.07) for GC mortality and 0.93 (95% CI, 0.68-1.28) for other UGI disease mortality. Sensitivity analysis reveals the result for Japan may potentially be biased. CONCLUSIONS: South Korea's nationwide GC screening has apparent benefits, whereas the Japanese program's effectiveness is uncertain. The experiences of South Korea and Japan could serve as a reference for other countries.

RESUMEN

Telehealth is an emerging approach that uses technology to provide healthcare remotely. Recent publications have outlined the importance of supporting the transition to self-management of adolescents with allergic conditions. However, no synthesis of the evidence base on the use and impact of telehealth interventions for this purpose has been conducted to date. This review achieves these aims, in addition to exploring the language use surrounding these interventions, and their implementation. Four databases were searched systematically. References were independently screened by two reviewers. Methodological quality was assessed using the Mixed Methods Appraisal Tool. A narrative synthesis was undertaken. Eighteen articles were included, reporting on 15 telehealth interventions. A total of 86% targeted adolescents with asthma. Mobile applications were the most common telehealth modality used, followed by video-conferencing, web-based, virtual reality and artificial intelligence. Five intervention content categories were identified; educational, monitoring, behavioural, psychosocial and healthcare navigational. Peer and/or healthcare professional interaction, gamification and tailoring may increase engagement. The studies showed positive effects of the interventions or no difference from active controls, in self-management outcomes such as knowledge, health outcomes such as quality-of-life, and economic outcomes such as healthcare utilization. The most common implementation outcomes reported were acceptability, appropriateness, feasibility and fidelity.

RESUMEN

INTRODUCTION: Self-care is essential for nurses' wellbeing, with stress posing a major barrier. Research into self-care is often absorbed into studies of burnout or resilience. Understanding lived experiences of influences on nurses' self-care practices is essential. There is currently a paucity of literature on this topic. AIM: To explore mental health nurses' views about what influences their ability to self-care in relation to workplace stress and the impact on their practice and work environment. METHODS: An Interpretative Phenomenological Analysis approach was utilized. In-depth interviews explored how nurses perceived the influence of environment and relationships on self-care practices in the workplace. RESULTS: Participants' perceptions and experiences are embodied by the theme: the nurse bombarded, comprising two subordinate themes-the nurse consumed by the intensity of work and therapeutic relationships; and feeling vulnerable from colleague relationships and feeling undervalued. Participants described conflict between workload demands and expectations and the desire to provide optimal care. CONCLUSIONS: Stressful working environments pose major barriers to effective self-care. Feeling bombarded and vulnerable, impacts nurses' lives personally and professionally. IMPLICATIONS FOR PRACTICE: Mental health nurses' self-care is crucial for quality practice. Strategies to address relational, personal and environmental barriers to self-care are therefore necessary.

RESUMEN

Processing temperature has a significant influence on the composition and functionality of the resulting streams following microfiltration (MF) of skim milk. In this study, MF and diafiltration (DF) were performed at 4 or 50°C to produce ß-casein (ß-CN)-depleted and nondepleted (i.e., native casein profile) micellar casein isolate retentates, respectively. Microfiltration combined with extensive DF resulted in a 40% depletion of ß-CN at 4°C, whereas no ß-CN depletion occurred at 50°C. Microfiltration at 4°C led to higher transmission of calcium into permeates, with retentate generated at 4°C containing less total calcium compared with retentate generated at 50°C, based on the volume of retentate remaining. Higher heat stability at 120°C was measured for retentates generated at 4°C compared with those at 50°C, across all pH values measured. Retentates generated at 4°C also had significantly lower ionic calcium values at each pH compared with those generated at 50°C. Higher apparent viscosities at 4°C were measured for retentates generated at 4°C compared with retentates generated at 50°C, likely due to increased voluminosity of ß-CN-depleted casein micelles. The results of this study provide new information on how changing the composition of MF retentate, by appropriate control of processing temperature and DF, can alter physicochemical properties of casein micelles, with potential implications for ingredient functionality.

RESUMEN

Sweet and, to a lesser extent, acid whey protein ingredients can be used for the formulation of infant nutritional products. Unlike acid whey, sweet whey contains caseinomacropeptide (CMP), a heat-stable peptide liberated from κ-casein during cheese and rennet casein manufacture. Four protein systems-sweet whey (SW) and acid whey (AW), with or without standardization for CMP protein content-were added to skim milk (50/50, wt/wt) and unheated or heated to 85 or 110°C. These 12 samples were assessed for physicochemical stability in the presence of added calcium at pH 6.8. The effect of CMP content on the physicochemical properties of the protein systems was also assessed. Without preheat treatment, mixtures of AW and skim milk (SM) were more heat stable than SW and SM, demonstrating the effect of whey protein type on heat stability. Preheat treatment of the SW in the presence of SM significantly improved the heat stability of the resultant protein systems on subsequent heating. All of the protein systems had significantly lower heat stability with the addition of Ca, although the reduction was significantly smaller for the heated protein systems than the unheated controls. The findings can help identify heating parameters and ingredients for optimizing processing stability and physicochemical characteristics of nutritional beverages such as infant formulations.

RESUMEN

OBJECTIVES: To examine trends in rates of self-harm among emergency department (ED) presenting older adults in Ireland over a 13-year period. DESIGN: Population-based study using data from the National Self-Harm Registry Ireland. SETTING: National hospital EDs. PARTICIPANTS: Older adults aged 60 years and over presenting with self-harm to hospital EDs in Ireland between January 1, 2007 and December 31, 2019. MEASUREMENTS: ED self-harm presentations. RESULTS: Between 2007 and 2019, there were 6931 presentations of self-harm in older adults. The average annual self-harm rate was 57.8 per 100,000 among older adults aged 60 years and over. Female rates were 1.1 times higher compared to their male counterparts (61.4 vs 53.9 per 100,000). Throughout the study time frame, females aged 60-69 years had the highest rates (88.1 per 100,000), while females aged 80 years and over had the lowest rates (18.7 per 100,000). Intentional drug overdose was the most commonly used method (75.5%), and alcohol was involved in 30.3% of presentations. Between the austerity and recession years (2007-2012), self-harm presentations were 7% higher compared to 2013-2019 (incidence rate ratio (IRR): 1.07 95% CI 1.02-1.13, p = 0.01). CONCLUSIONS: Findings indicate that self-harm in older adults remains a concern with approximately 533 presentations per year in Ireland. While in younger age groups, females report higher rates of self-harm, this gender difference was reversed in the oldest age group (80 years and over), with higher rates of self-harm among males. Austerity/recession years (2007-2012) had significantly higher rates of self-harm compared to subsequent years.

RESUMEN

It is acknowledged that health technology assessment (HTA) is an inherently value-based activity that makes use of normative reasoning alongside empirical evidence. But the language used to conceptualise and articulate HTA's normative aspects is demonstrably unnuanced, imprecise, and inconsistently employed, undermining transparency and preventing proper scrutiny of the rationales on which decisions are based. This paper - developed through a cross-disciplinary collaboration of 24 researchers with expertise in healthcare priority-setting - seeks to address this problem by offering a clear definition of key terms and distinguishing between the types of normative commitment invoked during HTA, thus providing a novel conceptual framework for the articulation of reasoning. Through application to a hypothetical case, it is illustrated how this framework can operate as a practical tool through which HTA practitioners and policymakers can enhance the transparency and coherence of their decision-making, while enabling others to hold them more easily to account. The framework is offered as a starting point for further discussion amongst those with a desire to enhance the legitimacy and fairness of HTA by facilitating practical public reasoning, in which decisions are made on behalf of the public, in public view, through a chain of reasoning that withstands ethical scrutiny.

RESUMEN

BACKGROUND: Identification of individuals at elevated risk can improve cancer screening programmes by permitting risk-adjusted screening intensities. Previous work introduced a prognostic model using sex, age and two preceding faecal haemoglobin concentrations to predict the risk of colorectal cancer (CRC) in the next screening round. Using data of 3 screening rounds, this model attained an area under the receiver-operating-characteristic curve (AUC) of 0.78 for predicting advanced neoplasia (AN). We validated this existing logistic regression (LR) model and attempted to improve it by applying a more flexible machine-learning approach. METHODS: We trained an existing LR and a newly developed random forest (RF) model using updated data from 219,257 third-round participants of the Dutch CRC screening programme until 2018. For both models, we performed two separate out-of-sample validations using 1,137,599 third-round participants after 2018 and 192,793 fourth-round participants from 2020 onwards. We evaluated the AUC and relative risks of the predicted high-risk groups for the outcomes AN and CRC. RESULTS: For third-round participants after 2018, the AUC for predicting AN was 0.77 (95% CI: 0.76-0.77) using LR and 0.77 (95% CI: 0.77-0.77) using RF. For fourth-round participants, the AUCs were 0.73 (95% CI: 0.72-0.74) and 0.73 (95% CI: 0.72-0.74) for the LR and RF models, respectively. For both models, the 5% with the highest predicted risk had a 7-fold risk of AN compared to average, whereas the lowest 80% had a risk below the population average for third-round participants. CONCLUSION: The LR is a valid risk prediction method in stool-based screening programmes. Although predictive performance declined marginally, the LR model still effectively predicted risk in subsequent screening rounds. An RF did not improve CRC risk prediction compared to an LR, probably due to the limited number of available explanatory variables. The LR remains the preferred prediction tool because of its interpretability.

RESUMEN

Engaging with children and adolescents in mental health settings who are exhibiting behaviours that challenge can often result in the use of seclusion, restraint and coercive practices. It is recognised that more therapeutic ways to engage this population are needed, adopting trauma informed interventions may provide a solution. The aim of this systematic review is to synthesize the evidence in relation to the effect of trauma-informed interventions on coercive practices in child and adolescent residential settings. The review is guided by elements of the Cochrane Handbook for Systematic Reviews of Interventions and reported using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist. Results were synthesized and reported narratively. Nine studies met the eligibility criteria for this review. There was a lack of homogeneity amongst the studies. The trauma-informed interventions used were typically multi-faceted, underpinned by a variety of approaches and sought to bring about changes to clinical practice. Most studies (n = 8) reported significant reductions in the use of restrictive practices following the implementation of a trauma informed approach. The use of a trauma-informed approach, underpinned by an organisational change or implementation strategy, have the potential to reduce coercive practices with children and adolescents. However, the included interventions were insufficiently described to draw strong conclusions.

RESUMEN

OBJECTIVES: Cost-effectiveness analysis (CEA) is the standard framework for informing the efficient allocation of scarce healthcare resources. The importance of considering all relevant intervention strategies and appropriate incremental comparisons have both long been recognized in CEA. Failure to apply methods correctly can lead to suboptimal policies. Our objective is to assess if CEAs of infant pneumococcal vaccination apply appropriate methods with respect to the completeness of strategies assessed and incremental comparisons between them. METHODS: We conducted a systematic search of the PubMed, Scopus, Embase, and Web of Science databases and performed a comparative analysis of the retrieved pneumococcal vaccination CEAs. We checked the appropriateness of the incremental analyses by attempting to replicate the published incremental cost-effectiveness (CE) ratios from the reported costs and health effects. RESULTS: Our search returned twenty-nine eligible articles. Most studies failed to recognize one or more intervention strategies (n = 21). Incremental comparisons were questionable in four CEAs and insufficient reporting of cost and health effect estimates was identified in three studies. Overall, we only found four studies that made appropriate comparisons between all strategies. Lastly, study findings appear to be strongly associated with manufacturer sponsorship. CONCLUSIONS: We found considerable scope for improvement regarding strategy comparison in the infant pneumococcal vaccination literature. To prevent overestimation of the CE of new vaccines, we urge greater adherence to existing guidelines recommending that all available strategies are evaluated to capture relevant comparators for CE evaluation. Closer adherence to existing guidelines will generate better evidence, leading to more effective vaccination policies.

RESUMEN

OBJECTIVE: To assess the range of strategies analysed in European cost-effectiveness analyses (CEAs) of colorectal cancer (CRC) screening with respect to the screening intervals, age ranges and test cut-offs used to define positivity, to examine how this might influence what strategies are found to be optimal, and compare them with the current screening policies with a focus on the screening interval. METHODS: We searched PubMed, Web of Science and Scopus for peer-reviewed, model-based CEAs of CRC screening. We included studies on average-risk European populations using the guaiac faecal occult blood test (gFOBT) or faecal immunochemical test (FIT). We adapted Drummond's ten-point checklist to appraise study quality. RESULTS: We included 39 studies that met the inclusion criteria. Biennial screening was the most frequently used interval which was analysed in 37 studies. Annual screening was assessed in 13 studies, all of which found it optimally cost-effective. Despite this, 25 of 26 European stool-based programmes use biennial screening. Many CEAs did not vary the age range, but the 14 that did generally found broader ranges optimal. Only 11 studies considered alternative FIT cut-offs, 9 of which found lower cut-offs superior. Conflicts between current policy and CEA evidence are less clear regarding age ranges and cut-offs. CONCLUSIONS: The existing CEA evidence indicates that the widely adopted biennial frequency of stool-based testing in Europe is suboptimal. It is likely that many more lives could be saved throughout Europe if programmes could be offered with more intensive annual screening.
