RESUMO
Suicide is a leading cause of death for young people globally. Professional organizations such as the American Academy of Pediatrics (AAP) recommend suicide screening for every young person at every healthcare contact and these guidelines are now being implemented across the US. To optimize deployment of these guidelines, we draw on insights from two parallel fields, implementation science - or the study of how to support clinicians in providing evidence-based care within organizational constraints - and behavioral economics, which centers human decision-making. In this brief review, we offer potential barriers to suicide screening and strategies to address barriers drawing on these two literatures, illustrating how best to integrate insights from these fields for maximal impact.
RESUMO
The advent of large language models (LLMs) such as ChatGPT has potential implications for psychological therapies such as cognitive behavioral therapy (CBT). We systematically investigated whether LLMs could recognize an unhelpful thought, examine its validity, and reframe it to a more helpful one. LLMs currently have the potential to offer reasonable suggestions for the identification and reframing of unhelpful thoughts but should not be relied on to lead CBT delivery.
RESUMO
BACKGROUND: Over 70 000 donor-conceived (DC) people have been born in the UK since 1991. Little is known about their long-term psychological outcomes and no systematic review has assessed these. OBJECTIVES: To conduct a systematic review of the psychological experiences of DC people through childhood and adulthood (Prospero: CRD42021257863). SEARCH STRATEGY: Searches of Cumulative Index to Nursing and Allied Health Literature (CINHAL), the Excerpta Medica database (Embase), MEDLINE® and PsycINFO, conducted on 4 January 2024. SELECTION CRITERIA: Quantitative and qualitative studies were included if: there were five or more participants; they were peer reviewed; and any DC psychological outcomes were assessed. No limits on date, language or country were applied. DATA COLLECTION AND ANALYSIS: Double screening, selection, data extraction and quality assessment were performed, using Joanna Briggs Institute (JBI) scoring. MAIN RESULTS: Fifty studies (with 4666 DC participants), mostly from high-income anglophone countries, with heterogeneity of design, populations and outcome measures, were included. Of 19 comparative studies, 14 found no difference in outcomes between DC and non-DC people, ten found better outcomes (in health, well-being, self-esteem and emotional warmth) and six found worse outcomes (increased autism spectrum disorder and attention deficit hyperactivity disorder, addiction issues, mental illness, disruptive behaviour and identity problems). Qualitative data revealed common themes relating to identity formation, mistrust and concerns regarding genetic heritage. The evidence regarding adulthood outcomes was very limited. CONCLUSIONS: The research on DC individuals presents a nuanced picture, with most studies suggesting comparable or improved outcomes in terms of well-being and relationships, but with a notable minority indicating higher rates of mental health and identity struggles. Qualitative findings underscore common negative experiences, whereas the early disclosure of DC status appears beneficial for psychological well-being.
RESUMO
BACKGROUND: Conduct disorder increases risks of educational dropout, future mental illness, and incarceration if untreated. First-line treatment of conduct disorder involves evidence-based parenting skills programs. Time-outs, a frequent tool in these programs, can be effective at improving behavior, and recent apps have been developed to aid this process. However, these apps promote the use of time-outs in inconsistent or developmentally inappropriate ways, potentially worsening behavior problems. Digital microinterventions like these apps could guide parents through high-quality time-outs in the moment, but current time-out apps lack features promoting adherence to the evidence-based best practice. Agile scrum is a respected approach in the software development industry. OBJECTIVE: We aimed to explore the feasibility of using the agile scrum approach to build a digital microintervention to help parents deliver an evidence-based time-out. METHODS: The agile scrum methodology was used. Four sprints were conducted. Figma software was used for app design and wireframing. Insights from 42 expert stakeholders were used during 3 sprint reviews. We consulted experts who were identified from councils around the Midlands region of the United Kingdom and charities through personal contacts and a snowballing approach. RESULTS: Over 4 development sprints from August 2022 to March 2023, the app was iteratively designed and refined based on consultation with a diverse group of 42 experts who shared their knowledge about the content of common parenting programs and the challenges parents commonly face. Modifications made throughout the process resulted in significant app enhancements, including tailored timer algorithms and enhanced readability, as well as an onboarding zone, mindfulness module, and pictorial information to increase inclusivity. By the end of the fourth sprint, the app was deemed ready for home use by stakeholders, demonstrating the effectiveness of our agile scrum development approach. CONCLUSIONS: We developed an app to support parents to use the evidence-based time-out technique. We recommend the agile scrum approach to create mobile health apps. Our experience highlights the valuable role that frontline health and social care professionals, particularly those working with vulnerable families, can play as experts in scrum reviews. There is a need for research to both evaluate the impact of digital microinterventions on child behavioral change and also create digital microinterventions that cater to non-English speakers and individuals who participate in parenting programs in settings outside the United Kingdom.
RESUMO
We recently demonstrated that acute oral ketone monoester intake induces a stimulation of postprandial myofibrillar protein synthesis rates comparable to that elicited following the ingestion of 10 g whey protein or their coingestion. The present investigation aimed to determine the acute effects of ingesting a ketone monoester, whey protein, or their coingestion on mechanistic target of rapamycin (mTOR)-related protein-protein colocalization and intracellular trafficking in human skeletal muscle. In a randomized, double-blind, parallel group design, 36 healthy recreationally active young males (age: 24.2 ± 4.1 yr) ingested either: 1) 0.36 g·kg-1 bodyweight of the ketone monoester (R)-3-hydroxybutyl (R)-3-hydroxybutyrate (KET), 2) 10 g whey protein (PRO), or 3) the combination of both (KET + PRO). Muscle biopsies were obtained in the overnight postabsorptive state (basal conditions), and at 120 and 300 min in the postprandial period for immunofluorescence assessment of protein translocation and colocalization of mTOR-related signaling molecules. All treatments resulted in a significant (Interaction: P < 0.0001) decrease in tuberous sclerosis complex 2 (TSC2)-Ras homolog enriched in brain (Rheb) colocalization at 120 min versus basal; however, the decrease was sustained at 300 min versus basal (P < 0.0001) only in KET + PRO. PRO and KET + PRO increased (Interaction: P < 0.0001) mTOR-Rheb colocalization at 120 min versus basal; however, KET + PRO resulted in a sustained increase in mTOR-Rheb colocalization at 300 min that was greater than KET and PRO. Treatment intake increased mTOR-wheat germ agglutinin (WGA) colocalization at 120 and 300 min (Time: P = 0.0031), suggesting translocation toward the fiber periphery. These findings demonstrate that ketone monoester intake can influence the spatial mechanisms involved in the regulation of mTORC1 in human skeletal muscle.NEW & NOTEWORTHY We explored the effects of a ketone monoester (KET), whey protein (PRO), or their coingestion (KET + PRO) on mTOR-related protein-protein colocalization and intracellular trafficking in human muscle. All treatments decreased TSC2-Rheb colocalization at 120 minutes; however, KET + PRO sustained the decrease at 300 min. Only PRO and KET + PRO increased mTOR-Rheb colocalization; however, the increase at 300 min was greater in KET + PRO. Treatment intake increased mTOR-WGA colocalization, suggesting translocation to the fiber periphery. Ketone bodies influence the spatial regulation of mTOR.

BACKGROUND: Implementation science in health is an interdisciplinary field with an emphasis on supporting behavior change required when clinicians and other actors implement evidence-based practices within organizational constraints. Behavioral economics has emerged in parallel and works towards developing realistic models of how humans behave and categorizes a wide range of features of choices that can influence behavior. We argue that implementation science can be enhanced by the incorporation of approaches from behavioral economics. Main body First, we provide a general overview of implementation science and ways in which implementation science has been limited to date. Second, we review principles of behavioral economics and describe how concepts from BE have been successfully applied to healthcare including nudges deployed in the electronic health record. For example, de-implementation of low-value prescribing has been supported by changing the default in the electronic health record. We then describe what a behavioral economics lens offers to existing implementation science theories, models and frameworks, including rich and realistic models of human behavior, additional research methods such as pre-mortems and behavioral design, and low-cost and scalable implementation strategies. We argue that insights from behavioral economics can guide the design of implementation strategies and the interpretation of implementation studies. Key objections to incorporating behavioral economics are addressed, including concerns about sustainment and at what level the strategies work. CONCLUSION: Scholars should consider augmenting implementation science theories, models, and frameworks with relevant insights from behavioral economics. By drawing on these additional insights, implementation scientists have the potential to boost efforts to expand the provision and availability of high quality care.

There is a need for all industries, including healthcare, to reduce their greenhouse gas emissions. In anaesthetic practice, this not only requires a reduction in resource use and waste, but also a shift away from inhaled anaesthetic gases and towards alternatives with a lower carbon footprint. As inhalational anaesthesia produces greenhouse gas emissions at the point of use, achieving sustainable anaesthetic practice involves individual practitioner behaviour change. However, changing the practice of healthcare professionals raises potential ethical issues. The purpose of this paper is twofold. First, we discuss what moral duties anaesthetic practitioners have when it comes to practices that impact the environment. We argue that behaviour change among practitioners to align with certain moral responsibilities must be supplemented with an account of institutional duties to support this. In other words, we argue that institutions and those in power have second-order responsibilities to ensure that practitioners can fulfil their first-order responsibilities to practice more sustainably. The second goal of the paper is to consider not just the nature of second-order responsibilities but the content. We assess four different ways that second-order responsibilities might be fulfilled within healthcare systems: removing certain anaesthetic agents, seeking consensus, education and methods from behavioural economics. We argue that, while each of these are a necessary part of the picture, some interventions like nudges have considerable advantages.
RESUMO
Skeletal muscle anabolism is driven by numerous stimuli such as growth factors, nutrients (i.e., amino acids, glucose), and mechanical stress. These stimuli are integrated by the mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) signal transduction cascade. In recent years, work from our laboratory and elsewhere has sought to unravel the molecular mechanisms underpinning the mTOR-related activation of muscle protein synthesis (MPS), as well as the spatial regulation of these mechanisms within the skeletal muscle cell. These studies have suggested that the skeletal muscle fiber periphery is a region of central importance in anabolism (i.e., growth/MPS). Indeed, the fiber periphery is replete with the substrates, molecular machinery, and translational apparatus necessary to facilitate MPS. This review provides a summary of the mechanisms underpinning the mTOR-associated activation of MPS from cell, rodent, and human studies. It also presents an overview of the spatial regulation of mTORC1 in response to anabolic stimuli and outlines the factors that distinguish the periphery of the cell as a highly notable region of skeletal muscle for the induction of MPS. Future research should seek to further explore the nutrient-induced activation of mTORC1 at the periphery of skeletal muscle fibers.
RESUMO
Small financial incentives have been proven effective at promoting healthy behaviours across medicine, including in psychiatry. There are a range of philosophical and practical objections to financial incentives. Drawing on the existing literature, specifically attempts to use financial incentives to promote antipsychotic adherence, we propose a 'patient-centred' view of evaluating financial incentive regimes. We argue that there is evidence that mental health patients like financial incentives, considering them fair and respectful. The enthusiasm of mental health patients for financial incentives lends support to their use, although it does not invalidate all objections against them.
RESUMO
OBJECTIVE: This systematic review will investigate the effects of financial incentives on engagement with and outcomes of evidence-based parenting skills programs to prevent and treat disruptive behavior disorders. INTRODUCTION: Evidence-based parenting skills programs are a first-line treatment in disruptive behavior disorders (ie, oppositional defiant disorder, conduct disorder, and attention-deficit/hyperactivity disorder), but fewer than half of referred parents complete these programs. When untreated, children affected by disruptive behavior disorders are at elevated risk of incarceration, drug misuse, and educational under-performance. Financial incentives can improve parents' engagement with parenting skills programs, and are increasingly popular strategies in public health policy to increase rates of compliance with health interventions. However, no previous systematic review or meta-analysis of financial incentives in parenting skills programs has been conducted. INCLUSION CRITERIA: Randomized controlled trials or quasi-experimental studies (ie, studies with a control group allocated through a non-random process) testing the effects of financial incentives on engagement will be included. Study participants must be in a guardian role to a person under 18 years of age. There will be no restrictions on country setting. Only English-language publications will be included. METHODS: We will search PubMed, CINAHL, Sociological Abstracts, Cochrane Trials, and PsycINFO databases for relevant articles. Two independent reviewers will screen abstracts for eligibility. Data will be extracted from eligible articles by 2 researchers and results will be presented in tabular and narrative format, along with a meta-analysis using a random effects model and assessment of heterogeneity. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42022336210.

Digital interventions to support parenting skills are popular but engagement can be low. Digital micro interventions such as apps targeting specific aspects of parenting are a novel development with the potential to overcome this challenge. Time out is an evidence-based component of many parenting skills training programmes and is an appropriate target for digital micro intervention. We describe the eight requirements of high-quality time out according to the literature and how these can be supported by an app. Searches of the App Store, Google Play, and Alexa Skills in the UK identified six apps designed to support time out. Current time out apps all promoted consistency, but they all risked low-quality time out through inappropriate initiation, duration, and termination. Professionals in child and adolescent mental health should explore the details of any digital micro interventions being used by parents for time out and provide appropriate counselling. We recommend that all future digital micro interventions in this area should incorporate evidence-based guidance.

Commitment devices (CDs) can help people overcome self-control problems to act on their plans and preferences. In these arrangements, people willingly make one of their options worse in order to change their own future behaviour, often by setting aside a sum of money that they will forfeit it if they fail to complete the planned action. Such applications of behavioural science have been used to help people stick to healthier lifestyle choices, overcome addictions and adhere to medication; they are acceptable to many patients and even relatively small sums can be effective. Some authors have objected to the use of nudges in healthcare. Engelen has listed nine potential objections to nudges in relation to means (why nudge rather than persuade?), ends (what action is being promoted?) and agents (who is nudging whom?). These objections are shown to lack force in the context of CDs. Instead, an analysis specific to the ethical issues in CDs is employed. CDs exclude certain groups including so-called 'naifs' and risk increasing health inequality. CDs may promote the wrong behaviour and people might legitimately change their minds. Intermediaries might encounter perverse incentives. Approaches to overcoming these problems are described and eight key ethical considerations for those considering implementing CDs in the future are described. Altogether this paper illustrates the advantages of appraising the ethics of behavioural science in medicine on a case-by-case basis.

The activation of the mechanistic target of rapamycin complex 1 (mTORC1), a master regulator of protein synthesis, by anabolic stimuli (such as muscle contraction or essential amino acids) involves its translocation to the cell periphery. Leucine is generally considered the most anabolic of amino acids for its ability to independently modulate muscle protein synthesis. However, it is currently unknown if free leucine impacts region-specific mTORC1-mediated phosphorylation events and protein-protein interactions. In this clinical trial (NCT03952884; registered May 16, 2019), we used immunofluorescence methods to investigate the role of dietary leucine on the postprandial regulation of mTORC1 and ribosomal protein S6 (RPS6), an important downstream readout of mTORC1 activity. Eight young, healthy, recreationally active males (n = 8; 23 ± 3 yrs) ingested 2 g of leucine with vastus lateralis biopsies collected at baseline, 30, 60, and 180 min postprandial. Leucine promoted mTOR translocation to the periphery (~ 18-29%; p ≤ 0.012) and enhanced mTOR localization with the lysosome (~ 16%; both p = 0.049) at 30 and 60 min post-feeding. p-RPS6Ser240/244 staining intensity, a readout of mTORC1 activity, was significantly elevated at all postprandial timepoints in both the total fiber (~ 14-30%; p ≤ 0.032) and peripheral regions (~ 16-33%; p ≤ 0.014). Additionally, total and peripheral p-RPS6Ser240/244 staining intensity at 60 min was positively correlated (r = 0.74, p = 0.036; r = 0.80, p = 0.016, respectively) with rates of myofibrillar protein synthesis over 180 min. The ability of leucine to activate mTORC1 in peripheral regions favors an enhanced rate of MPS, as this is the intracellular space thought to be replete with the cellular machinery that facilitates this anabolic process.

Skeletal muscle repair and maintenance are directly and indirectly supported by interstitial cell populations such as vascular cells and fibro-adipogenic progenitors (FAPs), a subset of which express Twist2 and possess direct myogenic potential. Furthermore, work in rodents has highlighted the potential of pericytes to act as progenitor cells, giving rise to muscle cells and transdifferentiating into endothelial cells. However, less is understood about these populations in human skeletal muscle. Here, we performed single-cell RNA sequencing (scRNAseq) on â¼2,000 cells isolated from the human semitendinosus muscle of young individuals. This demonstrated the presence of a vascular-related cell type that expressed pericyte and pan-endothelial genes that we localized to large blood vessels within skeletal muscle cross sections and termed endothelial-like pericytes (ELPCs). RNA velocity analysis indicated that ELPCs may represent a "transition state" between endothelial cells and pericytes. Analysis of published scRNAseq data sets revealed evidence for ELPCs in trunk and heart musculature, which showed transcriptional similarity. In addition, we identified a subset of FAPs expressing TWIST2 mRNA and protein. Human TWIST2-expressing cells were anatomically and transcriptionally comparable to mouse Twist2 cells as they were restricted to the myofiber interstitium, expressed fibrogenic genes but lacked satellite cell markers, and colocalized with the FAPs marker PDGFRα in human muscle cross sections. Taken together, these results highlight the complexity of stromal cells residing in human skeletal muscle and support the utility of scRNAseq for discovery and characterization of poorly described cell populations.

Home-based resistance exercise (RE) has become increasingly prevalent, but its effects on protein metabolism are understudied. We tested the effect of an essential amino acid formulation (EAA+: 9 g EAAs, 3 g leucine) and branched-chain amino acids (BCAAs: 6 g BCAAs, 3 g leucine), relative to a carbohydrate (CHO) placebo, on exogenous leucine retention and myofibrillar protein breakdown following dynamic bodyweight RE in a home-based setting. Twelve recreationally active adults (nine male, three female) participated in a double-blind, placebo-controlled, crossover study with four trial conditions: (i) RE and EAA+ (EX-EAA+); (ii) RE and BCAAs (EX-BCAA); (iii) RE and CHO placebo (EX-CHO); and (iv) rest and CHO placebo (REST-CHO). Total exogenous leucine oxidation and retention (estimates of whole-body anabolism) and urinary 3-methylhistidine:creatinine ratio (3MH:Cr; estimate of muscle catabolism) were assessed over 5 h post-supplement. Total exogenous leucine oxidation and retention in EX-EAA+ and EX-BCAA did not significantly differ (p = 0.116) but were greater than EX-CHO (p < 0.01). There was a main effect of condition on urinary 3MH:Cr (p = 0.034), with post hoc analysis revealing a trend (p = 0.096) for reduced urinary 3MH:Cr with EX-EAA+ (32%) compared to EX-CHO. By direct comparison, urinary 3MH:Cr was significantly lower (23%) in EX-EAA+ than EX-BCAA (p = 0.026). In summary, the ingestion of EAA+ or BCAA provided leucine that was ~60% retained for protein synthesis following home-based bodyweight RE, but EAA+ most effectively attenuated myofibrillar protein breakdown.

Interrupting prolonged sitting with intermittent exercise enhances postprandial glycemic control but has unknown effects on sensitizing skeletal muscle to dietary amino acids. We hypothesized that brief walking or body weight squats would enhance the utilization of dietary phenylalanine for myofibrillar protein synthesis (MyoPS) during prolonged sitting. Participants (7 males and 5 females; â¼23 yr; â¼25.1 kg/m2; â¼7,300 steps/day) completed three 7.5-h trials consisting of prolonged sitting (SIT) or sitting with intermittent (every 30 min) walking (WALK) or body weight squatting (SQUAT). Two mixed-macronutrient meals (â¼55:30:15% carbohydrate:fat:protein), enriched with l-[ring-2H5]phenylalanine or l-[ring-13C6]phenylalanine, were provided to mimic breakfast and lunch. Tracer incorporation into myofibrillar protein was determined from the vastus lateralis with MyoPS estimated using plasma enrichment as precursor surrogate. Phosphorylation of candidate anabolic signaling proteins was determined by immunoblotting. There was no difference between conditions (P ≥ 0.78) in the time course or area under the curve for plasma phenylalanine enrichment. MyoPS was greater (P < 0.05, weighted planned comparison) in SQUAT (0.103 ± 0.030%/h) and WALK (0.118 ± 0.037%/h) compared with SIT (0.080 ± 0.032%/h). When compared with SIT, there were moderate-to-large effect sizes, respectively, for SQUAT [effect size (ES) = 0.75; 95% CI -0.10-1.55] and WALK (ES = 1.10; 95% CI 0.20-1.91). Fold change in rpS6Ser240/244 phosphorylation was greater in SQUAT compared with SIT (7.6 ± 2.7 vs. 1.6 ± 0.45-fold, P < 0.05) with no difference (P ≥ 0.21) in any other targets measured (4E-BP1Thr37/46, eEF2Thr56, mTORSer2448, ERK1/2Thr202/Tyr204). Interrupting prolonged sitting with short "activity snacks" improves the utilization of dietary amino acids for MyoPS. The long-term impact of this practical lifestyle modification for muscle mass or quality should be investigated.NEW & NOTEWORTHY Prolonged sitting can impair postprandial glycemia, lipidemia, and insulin sensitivity regardless of previous health status. We demonstrate that interrupting prolonged sitting with brief periods of activity, such as body weight squats or short bouts of walking, improves the efficiency of dietary amino acid utilizations for muscle contractile protein synthesis. This further emphasizes the importance of minimizing sedentary time to improve the postprandial metabolism of all macronutrients.

OBJECTIVES: Incentives have been effectively used in several healthcare contexts. This systematic review aimed to ascertain whether incentives can improve antipsychotic adherence, what ethical and practical issues arise and whether existing evidence resolves these issues. DESIGN: Systematic review of MEDLINE, EMBASE and PsycINFO. Searches on 13 January 2021 (no start date) found papers on incentives for antipsychotics. Randomised controlled trials (RCTs), cohort studies, qualitative research and ethical analyses were included. Papers measuring impact on adherence were synthesised, then a typology of ethical and policy issues was compiled, finally the empirical literature was compared with this typology to describe current evidence and identify remaining research questions. RESULTS: 26 papers were included. 2 RCTs used contingent financial incentives for long-acting injectable antipsychotic preparations. Over 12 months, there were significantly larger increases in adherence among the intervention groups versus control groups in both RCTs. There were no consistently positive secondary outcomes. 39 ethical and practical issues were identified. 12 of these are amenable to empirical study but have not been researched and for 7 the current evidence is mixed. CONCLUSIONS: In keeping with other areas of healthcare, antipsychotic adherence can be increased with financial incentives. Payments of 2.5 times minimum wage changed behaviour. The typology of issues reported in this systematic review provides a template for future policy and ethical analysis. The persistence of the effect and the impact of incentives on intrinsic motivation require further research. PROSPERO REGISTRATION NUMBER: CRD42020222702.
