Perceiving greater variety among past conflicts with a focal goal reduces expected goal conflict.

Many important personal goals, such as health, career, finances, and social relationships, entail repeatedly performing the same (or similar) actions over time (e.g., to exercise daily or save money weekly). When pursuing such ongoing goals, people are likely to accumulate multiple experiences of goal conflict (e.g., multiple occasions when one failed to exercise or save as intended). How might these past experiences of goal conflict inform expectations about future goal pursuit? This research examines how the perceived relationship among past conflicts with a focal goal-in particular, perceived variety-shapes expectations. Perceived variety refers to the holistic assessment of differentiation (vs. similarity) among items in an assortment. Six studies demonstrate that perceiving greater variety among past conflicts with a focal goal decreases expectations of encountering conflict in the future. This occurs because perceiving greater variety makes the causes of past events seem collectively unstable (i.e., more temporary and one-off). Consequently, holding constant the number and content of past events, perceiving greater variety among past conflicts with a focal goal reduces expected goal conflict. Further, considering past events that prompt (i.e., motivate) less (vs. more) engagement in causal search (i.e., events that are less self-relevant, or positive) attenuates perceived variety's effects. The findings contribute to understanding of goal conflict, variety and similarity, and forecasting in goal pursuit. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Why Pursue a Doctorate? Findings From a Study of Doctorally Prepared RNs in an Integrated Healthcare System.

OBJECTIVE: The aim of this study was to examine the motivations and perceptions of RNs with completed doctorates in an integrated healthcare system. BACKGROUND: Historically, PhD preparation was the primary doctorate available for nurses, preparing them to conduct research and hold leadership positions. The recent growth of Doctor of Nursing Practice (DNP) programs that focus on either advanced clinical practice or executive competencies has significant implications for the future of nursing in practice settings. METHODS: A 30-item survey was sent to all 93 RNs at a healthcare system who have completed doctorates. RESULTS: A response rate of 71% found DNPs outnumber PhDs 3 to 1. PhDs are significantly more likely to perceive concrete benefits associated with their degrees, and DNPs are more likely to report that their degrees have not made a difference in their jobs. CONCLUSIONS: Leaders in practice and education must collaborate to ensure that both DNPs and PhDs are engaged in positions that use their highest level of competence in any setting.

Protocol for a prospective, randomized, controlled trial of Mental Contrasting with Implementation Intentions (MCII) to enhance the effectiveness of VA's MOVE! weight management program: WOOP (Wish, Outcome, Obstacle, Plan) VA.

INTRODUCTION: Intensive weight management programs are effective but often have low enrollment and high attrition. Lack of motivation is a key psychological barrier to enrollment, engagement, and weight loss. Mental Contrasting with Implementation Intentions (MCII) is a unique imagery technique that increases motivation for behavior change. We describe our study protocol to assess the efficacy and implementation of MCII to enhance the effectiveness of VA's MOVE! or TeleMOVE! weight management programs using a procedure called "WOOP" (Wish, Outcome, Obstacle, Plan) for Veterans. We hypothesize that WOOP+MOVE! or TeleMOVE! (intervention) will lead to greater MOVE!/TeleMOVE! program engagment and consequently weight loss than MOVE!/TeleMOVE! alone (control). METHOD: Veterans are randomized to either the intervention or control. Both arms receive the either MOVE! or TeleMOVE! weight management programs. The intervention group receives an hour long WOOP training while the control group receives patient education. Both groups receive telephone follow up calls at 3 days, 4 weeks, and 2 months post-baseline. Eligible participants are Veterans (ages 18-70 years) with either obesity (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 25 kg/m2) and an obesity-associated co-morbidity. At baseline, 6 and 12 months, we assess weight, diet, physical activity in both groups. The primary outcome is mean percent weight change at 6 months. Secondary outcomes include changes in waist circumference, diet, physical activity, and dieting self-efficacy and engagement in regular physical activity. We assess implementation using the RE-AIM framework. CONCLUSION: If WOOP VA is found to be efficacious, it will be an important tool to facilitate weight management and improve weight outcomes. CLINICAL TRIAL REGISTRATION: NCT05014984.

Individuals' perceptions and expectations of nutrition care provided by doctors in Australia: A focus group study.

BACKGROUND AND OBJECTIVES: Doctors are well placed to facilitate nutrition care to support dietary improvements due, in part, to their regular contact with their patients. Limited literature exists which explores the perspective of patients regarding the nutrition care provided by medical professionals across the continuum of care. This article explores the perspective of patients regarding perceptions of nutrition advice and care received from doctors and expectations of this care, including key skills and attributes the patients perceive as important. METHOD: Six online focus groups were conducted with Australian service users (n=32). RESULTS: Framework analysis identified four key themes: perceptions of doctors' role in nutrition care, expectations and experiences; the importance of individualised care; barriers and enablers to nutrition care; and topics, skills and attributes perceived as important in nutrition care. DISCUSSION: Patients have a desire for individualised and collaborative nutrition care but experienced systemic barriers in practice.

[Hypnosis: a complementary tool for managing adolescents affected by anorexia nervosa]. / Hypnose : outil complémentaire chez les adolescent-e-s souffrant d'anorexie mentale.

Anorexia Nervosa (AN) mainly affects adolescent girls and requires specialized, multidisciplinary care. In Geneva, the HUG's AliNEA unit and the pediatric hypnosis consultation have been collaborating since 2021 to integrate hypnosis into the management of AN. Hypnosis is seen as a complementary tool to the Maudsley therapeutic model, but not a miracle solution. It needs to be adapted to each patient's individual needs and to the different phases of treatment : re-association with the body, reinforcement of motivation, exploration of interpersonal relationships and consolidation of progress. Although scientific evidence is limited, patient testimonials underline its beneficial potential as a non-medicinal, individualized form of support.

L'anorexie mentale (AM) affecte principalement les adolescentes et requiert une prise en charge spécialisée et multidisciplinaire. Aux Hôpitaux universitaires de Genève (HUG), l'unité AliNEA et la consultation d'hypnose pédiatrique collaborent depuis 2021 pour intégrer l'hypnose dans la prise en charge de l'AM. L'hypnose est considérée comme un outil complémentaire au modèle thérapeutique Maudsley, mais non une solution miracle. Elle nécessite une adaptation aux besoins individuels de chaque patiente et aux différentes phases de la prise en charge : réassociation avec le corps, renforcement de la motivation, exploration des relations interpersonnelles et consolidation des progrès. Bien que les preuves scientifiques soient limitées, les témoignages des patientes soulignent son potentiel bénéfice comme soutien non médicamenteux et individualisé.

Pre-post evaluation of the emotions and motivations for transformative action of medical students in Germany after two different planetary health educational interventions.

BACKGROUND: Climate change is the greatest threat to human health. Medical students, as future health-care workers, are important in promoting sustainable behaviours, which are strongly associated with individuals' emotional responses to climate change. At Würzburg University Hospital (Würzburg, Germany), a one-term optional course (40 learning units) about planetary health and two lectures within the curricular course Environmental Medicine were introduced in 2021. We aimed to examine the effects of these courses on the emotions and motivations of students in acting against climate change. METHODS: We surveyed medical students from both courses during four consecutive terms during 2021-23 with a pre-post design using an anonymous online questionnaire on EvaSys. The survey consisted of 20 closed questions based on a 5-point Likert scale and six open questions. Quantitative data were analysed with SPSS version 28.0.1.1. Qualitative data were analysed with Kuckartz' qualitative content analysis. FINDINGS: 458 students were initially involved (349 [76%] in the lectures and 109 [24%] in the optional course) and 396 students were involved until the final date (288 [73%] in the lectures and 108 [27%] in the optional course). Mean response rate was 389 (85%) of 458 students pre-survey and 315 (80%) of 396 post-survey. The most frequently reported initial emotions of medical students from both cohorts were "helplessness" (220 [57%] of 389), "fear" (197 [51%]), and "disappointment" (171 [44%]). Only 82 (21%) of 389 students reported having "motivation to act" and 45 (12%) reported having "confidence". When comparing 176 matched pre-lecture and post-lecture Likert scale values of reported emotions, we observed a significant decrease in "helplessness" (mean difference -0·37, 95% CI -0·2 to -0·53; p<0·0001; d=0·34) and "disappointment" (-0·35, -0·2 to -0·49; p<0·0001; d=0·36) and a significant increase in "confidence" (0·67, 0·82 to 0·51; p<0·0001; d=0·65 and "motivation to act" (0·4, 0·53 to 0·27; p<0·0001; d=0·46). Students associated these changes with options for action offered in the lecture. INTERPRETATION: This pre-post evaluation provides evidence for a positive effect of planetary health education at the university level. Educators should focus on options for action and create space for improving emotional resilience within courses. FUNDING: None.

Cross-cultural experiences and self-development: a psychobiographical study of Bruce Lee.

A common challenge people face in today's cross-cultural world is how to solve a series of adaptation problems caused by cultural conflict. Exploring Bruce Lee's successful cross-cultural experiences through psychobiography offers some inspiration and thoughts. How did Bruce Lee successfully integrate martial arts, symbolising the Eastern culture, with films representing the Western culture, finally propelling kung fu films onto the international stage? Numerous publicly available materials about Bruce Lee were collected for this study, and the research data were evaluated using thematic analysis. Bruce Lee's success benefitted from reconstructing cultural environment information and exercising his initiative to shape a new cultural environment. His life experiences reflect individual cognition behaviour and social and cultural environments as two aspects of a dynamic circulation system and show that the two have reached internal and spiralling harmony through mutual integration. In the context of the Oriental collectivism culture's family narrative, Chinese adults' personality development features the unique theme of 'inheritance and innovation'. Dealing with the relationship between self-actualisation and familism is another important and challenging task in developing the Chinese personality.

Exploring the Use of Persuasive System Design Principles to Enhance Medication Incident Reporting and Learning Systems: Scoping Reviews and Persuasive Design Assessment.

BACKGROUND: Medication incidents (MIs) causing harm to patients have far-reaching consequences for patients, pharmacists, public health, business practice, and governance policy. Medication Incident Reporting and Learning Systems (MIRLS) have been implemented to mitigate such incidents and promote continuous quality improvement in community pharmacies in Canada. They aim to collect and analyze MIs for the implementation of incident preventive strategies to increase safety in community pharmacy practice. However, this goal remains inhibited owing to the persistent barriers that pharmacies face when using these systems. OBJECTIVE: This study aims to investigate the harms caused by medication incidents and technological barriers to reporting and identify opportunities to incorporate persuasive design strategies in MIRLS to motivate reporting. METHODS: We conducted 2 scoping reviews to provide insights on the relationship between medication errors and patient harm and the information system-based barriers militating against reporting. Seven databases were searched in each scoping review, including PubMed, Public Health Database, ProQuest, Scopus, ACM Library, Global Health, and Google Scholar. Next, we analyzed one of the most widely used MIRLS in Canada using the Persuasive System Design (PSD) taxonomy-a framework for analyzing, designing, and evaluating persuasive systems. This framework applies behavioral theories from social psychology in the design of technology-based systems to motivate behavior change. Independent assessors familiar with MIRLS reported the degree of persuasion built into the system using the 4 categories of PSD strategies: primary task, dialogue, social, and credibility support. RESULTS: Overall, 17 articles were included in the first scoping review, and 1 article was included in the second scoping review. In the first review, significant or serious harm was the most frequent harm (11/17, 65%), followed by death or fatal harm (7/17, 41%). In the second review, the authors found that iterative design could improve the usability of an MIRLS; however, data security and validation of reports remained an issue to be addressed. Regarding the MIRLS that we assessed, participants considered most of the primary task, dialogue, and credibility support strategies in the PSD taxonomy as important and useful; however, they were not comfortable with some of the social strategies such as cooperation. We found that the assessed system supported a number of persuasive strategies from the PSD taxonomy; however, we identified additional strategies such as tunneling, simulation, suggestion, praise, reward, reminder, authority, and verifiability that could further enhance the perceived persuasiveness and value of the system. CONCLUSIONS: MIRLS, equipped with persuasive features, can become powerful motivational tools to promote safer medication practices in community pharmacies. They have the potential to highlight the value of MI reporting and increase the readiness of pharmacists to report incidents. The proposed persuasive design guidelines can help system developers and community pharmacy managers realize more effective MIRLS.

Exploring the effectiveness of virtual and in-person instruction in culinary medicine: a survey-based study.

BACKGROUND: Culinary medicine, which has recently increased in popularity in medical education, incorporates food and nutritional interventions with principles of disease prevention and treatment. The ultimate goal is to improve overall health outcomes. The growing prevalence of diet-related chronic diseases indicates the need for physicians to have a deeper understanding of the interplay between nutrition and disease. Incorporating culinary medicine into medical education can equip medical students with the necessary skills and knowledge to promote better patient outcomes. The purpose of this study was to evaluate students' perceptions of their foundational knowledge of a culinary medicine course after completion of the course for first- and second-year medical students at the PCOM (Philadelphia College of Osteopathic Medicine). We will also examine the difference between methods of instruction in relation to constructs discussed of knowledge gained and enjoyment of the course. METHODS: This retrospective cohort study was conducted using SurveyMonkey by Momentive. Data were collected from osteopathic medical students who enrolled in a culinary medicine course at the PCOM from 2018 to 2022 through the completion of a post-course survey. The methods of instruction included either a virtual or in-person classroom. The statistical analysis for this study was conducted using IBM SPSS Statistics version 28. To compare methods of instruction, the statistical analyses used included descriptive statistics, chi-square analysis, one-way ANOVA, and independent sample one-sided t tests. RESULTS: A total of 360 out of 430 participants, spanning the years 2018 to 2022, completed the course requirements and participated in the online survey. There was a valid sample size of 249 for the in-person group and 111 for the virtual instruction group. The knowledge gained construct consisted of five survey questions, for a total possible score of 25, while the enjoyment construct consisted of two questions, for a total possible score of 10. A statistically significant difference in knowledge gained was identified by one-way ANOVA, F (4,355) = 3.853, p =.004. Additionally, there was a statistically significant difference in enjoyment of the course between class years, F (4,356) = 11.977, p <.001. Independent sample t-tests revealed a statistically significant difference in enjoyment between the two methods (p <.001) even after accounting for unequal variances, with Cohen's d equal to 0.807, indicating a moderate effect size. CONCLUSIONS: The findings of this study suggest that overall, students were highly satisfied with the Culinary Medicine course over a five-year period. The study suggested that students who participated in in-person courses benefitted more than did the virtual students in terms of knowledge gained and enjoyment. The 360 students who completed the Culinary Medicine course were highly satisfied with the information and skills they acquired.

Neural correlates of the addictions neuroclinical assessment (ANA) incentive salience factor among individuals with alcohol use disorder.

The Addictions Neuroclinical Assessment (ANA) is a recently-developed framework offering a more holistic understanding of three neurofunctional and behavioral domains that reflect the neurobiological dysfunction seen in alcohol use disorder (AUD). While the ANA domains have been well-validated across independent laboratories, there is a critical need to identify neural markers that subserve the proposed neurofunctional domains. The current study involves secondary data analysis of a two-week experimental medication trial of ibudilast (50 mg BID). Forty-five non-treatment-seeking participants with AUD (17F / 28 M) completed a battery of validated behavioral assessments forming the basis of their incentive salience factor score, computed via factor analysis, as well as a functional neuroimaging (fMRI) task assessing their neural reactivity to visual alcohol cues after being on placebo or ibudilast for 7 days. General linear models were conducted to examine the relationship between incentive salience and neural alcohol cue-reactivity in the ventral and dorsal stratum. Whole-brain generalized linear model analyses were conducted to examine associations between neural alcohol cue-reactivity and incentive salience. Age, sex, medication, and smoking status were included as covariates. Incentive salience was not associated with cue-elicited activation in the dorsal or ventral striatum. Incentive salience was significantly positively correlated (p < 0.05) with alcohol cue-elicited brain activation in reward-learning and affective regions including the insula and posterior cingulate cortices, bilateral precuneus, and bilateral precentral gyri. The ANA incentive salience factor is reflected in brain circuitry important for reward learning and emotion processing. Identifying a sub-phenotype of AUD characterized by increased incentive salience to alcohol cues allows for precision medicine approaches, i.e. treatments specifically targeting craving and reward from alcohol use. This study serves as a preliminary bio-behavioral validation for the incentive salience factor of the ANA. Further studies validating the neural correlates of other ANA factors, as well as replication in larger samples, appear warranted.

Dissociable encoding of motivated behavior by parallel thalamo-striatal projections.

The successful pursuit of goals requires the coordinated execution and termination of actions that lead to positive outcomes. This process relies on motivational states that are guided by internal drivers, such as hunger or fear. However, the mechanisms by which the brain tracks motivational states to shape instrumental actions are not fully understood. The paraventricular nucleus of the thalamus (PVT) is a midline thalamic nucleus that shapes motivated behaviors via its projections to the nucleus accumbens (NAc)1,2,3,4,5,6,7,8 and monitors internal state via interoceptive inputs from the hypothalamus and brainstem.3,9,10,11,12,13,14 Recent studies indicate that the PVT can be subdivided into two major neuronal subpopulations, namely PVTD2(+) and PVTD2(-), which differ in genetic identity, functionality, and anatomical connectivity to other brain regions, including the NAc.4,15,16 In this study, we used fiber photometry to investigate the in vivo dynamics of these two distinct PVT neuronal types in mice performing a foraging-like behavioral task. We discovered that PVTD2(+) and PVTD2(-) neurons encode the execution and termination of goal-oriented actions, respectively. Furthermore, activity in the PVTD2(+) neuronal population mirrored motivation parameters such as vigor and satiety. Similarly, PVTD2(-) neurons also mirrored some of these parameters, but to a much lesser extent. Importantly, these features were largely preserved when activity in PVT projections to the NAc was selectively assessed. Collectively, our results highlight the existence of two parallel thalamo-striatal projections that participate in the dynamic regulation of goal pursuits and provide insight into the mechanisms by which the brain tracks motivational states to shape instrumental actions.

Understanding the diabetes self-care behaviour in rural areas: Perspective of patients with type 2 diabetes mellitus and healthcare professionals.

BACKGROUND: Diabetes self-care behaviour plays a crucial role in managing the diabetes effectively and preventing complications. Patients with type 2 diabetes mellitus (T2DM) and health care professionals (HCPs) of rural areas often face unique challenges when it comes to diabetes self-care practices (SCPs). Therefore, this study aim to explore the perspectives of patients with T2DM and HCPs on diabetes SCPs. METHODS: Eight focus group discussions (FGDs) among individuals with T2DM and In-depth interviews (IDIs) with 15 HCPs were conducted in rural areas of Punjab, North India. Capability, Opportunity, Motivation, and Behaviour model (COM-B) was employed for thematic framework analyses. RESULTS: The study participants perceived that a limited understanding of diabetes mellitus (DM), beliefs in alternative therapies, drug side effects, attitudes towards DM (psychological capability), comorbidities (physical capability), family support (social opportunity), financial and time constraints, and weather conditions (physical opportunity) contributed to lack of DM SCPs. Physicians' guidance and support were motivating them to adhere to SCPs, especially when aligned with their sense of self-efficacy (reflective motivation). HCPs constraints in providing patient-centred care are due to training limitations (psychological capability) and a lack of essential resources (physical opportunities). Participants expressed need for comprehensive diabetes care (automatic motivation) through structured diabetes education intervention to improve diabetes SCPs. CONCLUSIONS: The study findings indicate that various factors influence diabetes SCPs from the perspectives of both patients with T2DM and HCPs and emphasizes the need for a multi-faceted approach to improve diabetes SCPs in rural areas. Implementing a structured diabetes self-care intervention strategy in rural areas may help for preventing and mitigating the impact of diabetes-related complications in rural areas.

What moves truck drivers? A person-centered perspective on workplace physical activity promotion.

Objectives. In developing physical activity (PA) promotion measures in the workplace, individual needs of the target groups must be considered. For this reason, this study aimed to qualitatively identify the individual needs for an increase of PA in truck drivers, representing a neglected working group in terms of PA promotion. Methods. Semi-structured interviews were conducted (N = 19; mean age 50.5 years, SD 11.4 years; 10.5% female). The interview guide was based on the COM-B model to identify needs related to PA behavior in terms of capabilities, opportunities and motivation. The interviews were transcribed and coded by two independent investigators. Results. Altogether, the codes encompassed 395 statements, and the code system contained 14 codes. Three additional codes described further individual needs related to other health behaviors (nutrition, recreation) or external incentives for health interventions. Conclusion. The results reveal a variety of needs that are fundamental to the development of PA-promoting interventions for truck drivers. These needs appear to be closely linked, so a combination of capabilities, opportunities and/or motivation should be considered when developing holistic interventions. An example would be linking automatic motivation and psychological capabilities that encompass motivational techniques combined with information for psychoeducation of truck drivers.

Development and initial testing of mindful journey: a digital mindfulness-based intervention for promoting recovery from Substance use disorder.

BACKGROUND/OBJECTIVES: There is a great unmet need for accessible adjunctive interventions to promote long-term recovery from substance use disorder (SUD). This study aimed to iteratively develop and test the initial feasibility and acceptability of Mindful Journey, a novel digital mindfulness-based intervention for promoting recovery among individuals with SUD. PATIENTS/MATERIALS: Ten adults receiving outpatient treatment for SUD. METHODS: Phase 1 (n = 5) involved developing and testing a single introductory digital lesson. Phase 2 included a separate sample (n = 5) and involved testing all 15 digital lessons (each 30- to 45-minutes) over a 6-week period, while also receiving weekly brief phone coaching for motivational/technical support. RESULTS: Across both phases, quantitative ratings (rated on a 5-point scale) were all at or above a 4 (corresponding with 'agree') for key acceptability dimensions, such as usability, understandability, appeal of visual content, how engaging the content was, and helpfulness for recovery. Additionally, in both phases, qualitative feedback indicated that participants particularly appreciated the BOAT (Breath, Observe, Accept, Take a Moment) tool for breaking down mindfulness into steps. Qualitative feedback was used to iteratively refine the intervention. For example, based on feedback, we added a second core mindfulness tool, the SOAK (Stop, Observe, Appreciate, Keep Curious), and we added more example clients and group therapy videos. In Phase 2, 4 out of 5 participants completed all 15 lessons, providing initial evidence of feasibility. Participants reported that the phone coaching motivated them to use the app. The final version of Mindful Journey was a smartphone app with additional features, including brief on-the-go audio exercises and a library of mindfulness practices. Although, participants used these additional features infrequently. CONCLUSIONS: Based on promising initial findings, future acceptability and feasibility testing in a larger sample is warranted. Future versions might include push notifications to facilitate engagement in the additional app features.

Deep brain stimulation of the central thalamus restores arousal and motivation in a zolpidem-responsive patient with akinetic mutism after severe brain injury.

After severe brain injury, zolpidem is known to cause spectacular, often short-lived, restorations of brain functions in a small subgroup of patients. Previously, we showed that these zolpidem-induced neurological recoveries can be paralleled by significant changes in functional connectivity throughout the brain. Deep brain stimulation (DBS) is a neurosurgical intervention known to modulate functional connectivity in a wide variety of neurological disorders. In this study, we used DBS to restore arousal and motivation in a zolpidem-responsive patient with severe brain injury and a concomitant disorder of diminished motivation, more than 10 years after surviving hypoxic ischemia. We found that DBS of the central thalamus, targeted at the centromedian-parafascicular complex, immediately restored arousal and was able to transition the patient from a state of deep sleep to full wakefulness. Moreover, DBS was associated with temporary restoration of communication and ability to walk and eat in an otherwise wheelchair-bound and mute patient. With the use of magnetoencephalography (MEG), we revealed that DBS was generally associated with a marked decrease in aberrantly high levels of functional connectivity throughout the brain, mimicking the effects of zolpidem. These results imply that 'pathological hyperconnectivity' after severe brain injury can be associated with reduced arousal and behavioral performance and that DBS is able to modulate connectivity towards a 'healthier baseline' with lower synchronization, and, can restore functional brain networks long after severe brain injury. The presence of hyperconnectivity after brain injury may be a possible future marker for a patient's responsiveness for restorative interventions, such as DBS, and suggests that lower degrees of overall brain synchronization may be conducive to cognition and behavioral responsiveness.

Independent inhibitory control mechanisms for aggressive motivation and action.

Social behaviors often consist of a motivational phase followed by action. Here we show that neurons in the ventromedial hypothalamus ventrolateral area (VMHvl) of mice encode the temporal sequence of aggressive motivation to action. The VMHvl receives local inhibitory input (VMHvl shell) and long-range input from the medial preoptic area (MPO) with functional coupling to neurons with specific temporal profiles. Encoding models reveal that during aggression, VMHvl shellvgat+ activity peaks at the start of an attack, whereas activity from the MPO-VMHvlvgat+ input peaks at specific interaction endpoints. Activation of the MPO-VMHvlvgat+ input promotes and prolongs a low motivation state, whereas activation of VMHvl shellvgat+ results in action-related deficits, acutely terminating attack. Moreover, stimulation of MPO-VMHvlvgat+ input is positively valenced and anxiolytic. Together, these data demonstrate how distinct inhibitory inputs to the hypothalamus can independently gate the motivational and action phases of aggression through a single locus of control.

Dietary Supplement Use in Transmasculine People: Results of an Online Survey of Volunteer Adults.

INTRODUCTION: Health inequities and disparities in nutrition research exist among transmasculine people. A dearth of evidence on dietary supplement use and motivations exist, partially due to constrained collection of sex and gender identity in national surveys. OBJECTIVE: We sought to investigate common motivations and use of dietary supplements in a voluntary survey of transmasculine people. METHODS: A total of 48 participants completed an online survey detailing dietary supplement use, motivations, and demographic information. RESULTS: 64.5 and 90.0% of participants reported use of 1+ dietary supplement within the past 30-days and during some point in their lifetime, respectively. Top reported product types used included multivitamins (52%), melatonin (52%), vitamin D (46%), vitamin C (35%), fish oil (33%), B-vitamins or B-complex (31%), iron (29%), green tea (29%), biotin (25%), cranberry (23%), zinc (23%), protein powder (23%), probiotics (23%), and calcium (21%). There was no relationship between the number of supplements reported and participant age, BMI, income, or mastectomy status (p > 0.05). Participants reported top motivations being for "improving my overall health" (60.4%), "maintaining health" (54.2%), to "supplement my diet due to not getting enough from food"(41.7%), "mental health" (39.6%), and to "prevent colds, boost immune system" (33.3%). CONCLUSION: Transmasculine people in our study reported a high use of dietary supplements. Differences in the types of products and number of products used, as well as specific motivations for use likely exist within this subpopulation, however, future nationally-representative longitudinal studies are needed to fully elucidate these patterns and for informing evidence-based nutrition guidance.

Optogenetic recruitment of hypothalamic corticotrophin-releasing-hormone (CRH) neurons reduces motivational drive.

Impaired motivational drive is a key feature of depression. Chronic stress is a known antecedent to the development of depression in humans and depressive-like states in animals. Whilst there is a clear relationship between stress and motivational drive, the mechanisms underpinning this association remain unclear. One hypothesis is that the endocrine system, via corticotropin-releasing hormone (CRH) in the paraventricular nucleus of the hypothalamus (PVN; PVNCRH), initiates a hormonal cascade resulting in glucocorticoid release, and that excessive glucocorticoids change brain circuit function to produce depression-related symptoms. Another mostly unexplored hypothesis is that the direct activity of PVNCRH neurons and their input to other stress- and reward-related brain regions drives these behaviors. To further understand the direct involvement of PVNCRH neurons in motivation, we used optogenetic stimulation to activate these neurons 1 h/day for 5 consecutive days and showed increased acute stress-related behaviors and long-lasting deficits in the motivational drive for sucrose. This was associated with increased Fos-protein expression in the lateral hypothalamus (LH). Direct stimulation of the PVNCRH inputs in the LH produced a similar pattern of effects on sucrose motivation. Together, these data suggest that PVNCRH neuronal activity may be directly responsible for changes in motivational drive and that these behavioral changes may, in part, be driven by PVNCRH synaptic projections to the LH.

Contingency management is associated with positive changes in attitudes and reductions in cannabis use even after discontinuation of incentives among non-treatment seeking youth.

BACKGROUND: It is important to identify interventions that reduce harm in youth not motivated to change their cannabis use. This study evaluated how short-duration contingency management (CM) impacts cannabis use attitudes and behavior after abstinence incentives are discontinued among non-treatment seeking youth. METHODS: Participants (N=220) were randomized to 4 weeks of abstinence-based CM (CB-Abst; n=126) or monitoring (CB-Mon; n=94). Participants completed self-report and provided biochemical measures of cannabis exposure at baseline, end-of-intervention, and 4-week follow-up. Changes in self-reported cannabis use frequency (days/week; times/week) and biochemically verified creatinine-adjusted 11-nor-9-carboxy-tetrahydrocannabinol concentrations (CN-THCCOOH) were analyzed between groups from baseline to follow-up. In CB-Abst, cannabis use goals at end-of-intervention were described and changes in cannabis use at follow-up were explored by goals and cannabis use disorder (CUD) diagnosis. RESULTS: There was a group by visit interaction on cannabis use (days: beta=0.93, p=0.005; times: beta=0.71, p<0.001; CN-THCCOOH: beta=0.26, p=0.004), with reductions at follow-up detected only in CB-Abst. Following 4 weeks of abstinence, 68.4% of CB-Abst participants wanted to reduce or abstain from cannabis use following completion of CM. Those in CB-Abst who set end-of-intervention reduction goals and were without CUD had greater decreases in cannabis use frequency at follow-up (Goals*time on days/week: beta=-2.27, p<0.001; CUD*time on times/week: beta=0.48, SE=0.24, t=2.01, p=0.048). CONCLUSIONS: Findings support the utility of brief incentivized abstinence for generating motivation to reduce cannabis use and behavior change even after incentives end. This study supports CM as a potentially viable harm reduction strategy for those not yet ready to quit.

Neural encoding of musical expectations in a non-human primate.

The appreciation of music is a universal trait of humankind.1,2,3 Evidence supporting this notion includes the ubiquity of music across cultures4,5,6,7 and the natural predisposition toward music that humans display early in development.8,9,10 Are we musical animals because of species-specific predispositions? This question cannot be answered by relying on cross-cultural or developmental studies alone, as these cannot rule out enculturation.11 Instead, it calls for cross-species experiments testing whether homologous neural mechanisms underlying music perception are present in non-human primates. We present music to two rhesus monkeys, reared without musical exposure, while recording electroencephalography (EEG) and pupillometry. Monkeys exhibit higher engagement and neural encoding of expectations based on the previously seeded musical context when passively listening to real music as opposed to shuffled controls. We then compare human and monkey neural responses to the same stimuli and find a species-dependent contribution of two fundamental musical features-pitch and timing12-in generating expectations: while timing- and pitch-based expectations13 are similarly weighted in humans, monkeys rely on timing rather than pitch. Together, these results shed light on the phylogeny of music perception. They highlight monkeys' capacity for processing temporal structures beyond plain acoustic processing, and they identify a species-dependent contribution of time- and pitch-related features to the neural encoding of musical expectations.
