RESUMO

BACKGROUND AND AIMS: Whether gastric cancer (GC) precursor lesions progress to invasive cancer at similar rates globally remains unknown. We conducted a systematic review and meta-analysis to determine the progression of precursor lesions to GC in countries with low versus medium/high incidence. METHODS: We searched relevant databases for studies reporting the progression of endoscopically confirmed precursor lesions to GC. Studies were stratified by low (<6 per 100,000) or medium/high (≥6 per 100,000) GC incidence countries. Random-effects models were used to estimate the progression rates of atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia to GC per 1,000 person-years. RESULTS: Among the 5,829 studies identified, 44 met our inclusion criteria. The global pooled estimates of the progression rate per 1,000 person-years were 2.09 (95% CI 1.46-2.99), 2.89 (2.03-4.11) and 10.09 (5.23-19.49) for AG, IM, and dysplasia respectively. The estimated progression rates per 1,000 person-years for low versus medium/high GC incidence countries, respectively, were 0.97 (0.86-1.10) vs. 2.47 (1.70-2.99) for AG (p<0.01); 2.37 (1.43-3.92) vs. 3.47 (2.13-5.65) for IM (p=0.29); and 5.51 (2.92-10.39) vs. 14.80 (5.87-37.28) for dysplasia (p=0.08). There were no differences for progression of AG between groups when high quality studies were compared. CONCLUSION: Similar progression rates of IM and dysplasia were observed among low and medium/high GC incidence countries. This suggests that the potential benefits of surveillance for these lesions in low-risk regions may be comparable to those of population-wide interventions in high-risk regions. Further prospective studies are needed to confirm these findings and inform global screening and surveillance guidelines.

RESUMO

Lactoferrin (LF) and osteopontin (OPN) are bioactive milk proteins which can form heteroprotein complexes and complex coacervates. This research studied the effect of LF-OPN complexation and complex coacervation on the simulated infant gastrointestinal digestion of LF with subsequent examination of gut and bone health bioactivities in preclinical models. In an infant digestion model, the proteolytic profile of LF was unaltered by the pre-association of LF and OPN. Gastric proteolysis of LF was increased when the model gastric pH was reduced from 5.3 to 4.0, but less so when complexed with OPN. In a model of intestinal inflammation, undigested (79% inhibition) and gastric digestates (26% inhibition) of LF, but not gastrointestinal digestates, inhibited lipopolysaccharide (LPS)-induced NF-κB activation in intestinal epithelial cells. LF-OPN complexation sustained the inhibitory effect (21-43% of the undigested effect, depending on the type of complex) of LF after gastrointestinal digestion, suggesting that the peptides produced were different. In a neonatal rodent model used to study bone development, coacervating LF and OPN improved bone structures with a significant increase of trabecular proportion (BV/TV increase by 21.7%). This resulted in an 11.3% increase in stiffness of bones. Feeding the LF and OPN proteins in coacervate format also increased the levels of OPN, P1NP and M-CSF in blood, signifying a more pronounced impact on bone development. This research demonstrated that LF-OPN complexation and complex coacervation can delay simulated infant gastrointestinal digestion of LF and protect or improve the bioactivity of the proteins.

RESUMO

Racial and ethnic disparities in incidence and mortality are well documented for many types of cancer. As a result, there is understandable policy and clinical interest in race- and ethnicity-based clinical screening guidelines to address cancer health disparities. Despite the theoretical benefits, such proposals do not typically address associated ethical considerations. Using the examples of gastric cancer and esophageal adenocarcinoma, which have demonstrated disparities according to race and ethnicity, this article examines relevant ethical arguments in considering screening based on race and ethnicity.Race- and ethnicity-based clinical preventive care services have the potential to improve the balance of harms and benefits of screening. As a result, programs focused on high-risk racial or ethnic groups could offer a practical alternative to screening the general population, in which the screening yield may be too low to demonstrate sufficient effectiveness. However, designing screening according to socially based categorizations such as race or ethnicity is controversial and has the potential for intersectional stigma related to social identity or other structurally mediated environmental factors. Other ethical considerations include miscategorization, unintended negative effects on health disparities, disregard for underlying risk factors, and the psychological costs of being assigned higher risk.Given the ethical considerations, the practical application of race and ethnicity in cancer screening is most relevant in multicultural countries if and only if alternative proxies are not available. Even in those instances, policymakers and clinicians should carefully address the ethical considerations within the historical and cultural context of the intended population. Further research on alternative proxies, such as social determinants of health and culturally based characteristics, could provide more adequate factors for risk stratification.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

However, the included interventions were insufficiently described to draw strong conclusions.
