Immune system modulation & virus transmission during parasitism identified by multi-species transcriptomics of a declining insect biocontrol system.

BACKGROUND: The Argentine stem weevil (ASW, Listronotus bonariensis) is a significant pasture pest in Aotearoa New Zealand, primarily controlled by the parasitoid biocontrol agent Microctonus hyperodae. Despite providing effective control of ASW soon after release, M. hyperodae parasitism rates have since declined significantly, with ASW hypothesised to have evolved resistance to its biocontrol agent. While the parasitism arsenal of M. hyperodae has previously been investigated, revealing many venom components and an exogenous novel DNA virus Microctonus hyperodae filamentous virus (MhFV), the effects of said arsenal on gene expression in ASW during parasitism have not been examined. In this study, we performed a multi-species transcriptomic analysis to investigate the biology of ASW parasitism by M. hyperodae, as well as the decline in efficacy of this biocontrol system. RESULTS: The transcriptomic response of ASW to parasitism by M. hyperodae involves modulation of the weevil's innate immune system, flight muscle components, and lipid and glucose metabolism. The multispecies approach also revealed continued expression of venom components in parasitised ASW, as well as the transmission of MhFV to weevils during parasitism and some interrupted parasitism attempts. Transcriptomics did not detect a clear indication of parasitoid avoidance or other mechanisms to explain biocontrol decline. CONCLUSIONS: This study has expanded our understanding of interactions between M. hyperodae and ASW in a biocontrol system of critical importance to Aotearoa-New Zealand's agricultural economy. Transmission of MhFV to ASW during successful and interrupted parasitism attempts may link to a premature mortality phenomenon in ASW, hypothesised to be a result of a toxin-antitoxin system. Further research into MhFV and its potential role in ASW premature mortality is required to explore whether manipulation of this viral infection has the potential to increase biocontrol efficacy in future.

Former Inpatient Psychiatric Patients' Past Experiences With Traditional Frontline Staff and Their Thoughts on the Benefits of Peers as Part of Frontline Staff.

Little is known about how integrating peers into frontline staff might improve the quality of inpatient psychiatric care. In the current study, we interviewed 18 former adult patients of inpatient psychiatric facilities using semi-structured interviews. We first asked about positive and negative past experiences with traditional staff. We then asked participants to share their opinions on the potential benefits of peers as part of frontline staff. We identified themes through a joint inductive and deductive approach. Participants reported past positive experiences with traditional staff as being (a) personable and caring, (b) validating feelings and experiences, (c) de-escalating, and (d) providing agency. Past negative experiences included (a) not sharing information, (b) being inattentive, (c) not providing agency, (d) being dehumanizing/disrespectful, (e) incompetency, (f) escalating situations, and (g) being apathetic. Participants believed that peers as part of frontline staff could champion emotional needs in humanizing and nonjudgmental ways, help navigate the system, and disrupt power imbalances between staff and patients. Further research is needed to understand financial, organizational, and cultural barriers to integrating peers into frontline staff.

Investigating the impact of involuntary psychiatric hospitalization on youth and young adult trust and help-seeking in pathways to care.

PURPOSE: Few studies have focused on the experience of involuntary psychiatric hospitalization among youth, especially the impact of these experiences on engagement with mental health services post-discharge. In this study, we contribute to a deeper understanding of youth experiences of involuntary hospitalization (IH) and its subsequent impacts on trust, help-seeking, and engagement with clinicians. METHODS: The study utilized a grounded theory approach, conducting in-depth interviews with 40 youth and young adults (ages 16-27) who had experienced at least one prior involuntary hospitalization. RESULTS: Three quarters of the youth reported negative impacts of IH on trust, including unwillingness to disclose suicidal feelings or intentions. Selective non-disclosure of suicidal feelings was reported even in instances in which the participant continued to meet with providers following discharge. Factors identified as contributing to distrust included perceptions of inpatient treatment as more punitive than therapeutic, staff as more judgmental than empathetic, and hospitalization overall failing to meet therapeutic needs. Conversely, participants reporting more mixed experiences of hospitalization and simultaneously strong indirect benefits, including greater family support, diminished family judgement members and greater access to care. CONCLUSION: Findings draw attention to the ways in which coercive experiences may impact youth pathways to and through care. Additional research is needed to understand the impact of these experiences across larger samples, and their influence on downstream outcomes including engagement and long-term wellbeing. Finally, these data may inform the development and testing of inpatient and post-discharge interventions designed to mitigate potential harm.

The Effect of Centers for Medicare and Medicaid's Inpatient Psychiatric Facility Quality Reporting Program on the Use of Restraint and Seclusion.

BACKGROUND: Patients in inpatient psychiatry settings are uniquely vulnerable to harm. As sources of harm, research and policy efforts have specifically focused on minimizing and eliminating restraint and seclusion. The Centers for Medicare and Medicaid's Inpatient Psychiatric Facility Quality Reporting (IPFQR) program attempts to systematically measure and reduce restraint and seclusion. We evaluated facilities' response to the IPFQR program and differences by ownership, hypothesizing that facilities reporting these measures for the first time will show a greater reduction and that ownership will moderate this effect. METHODS: Using a difference-in-differences design and exploiting variation among facilities that previously reported on these measures to The Joint Commission, we examined the effect of the IPFQR public reporting program on the use and duration of restraint and seclusion from the end of 2012 through 2017. RESULTS: There were a total of 9705 observations of facilities among 1841 unique facilities. Results suggest the IPFQR program reduced duration of restraint by 48.96% [95% confidence interval (95% CI), 16.69%-68.73%] and seclusion by 53.54% (95% CI, 19.71%-73.12%). There was no change in odds of zero restraint and, among for-profits only, a decrease of 36.89% (95% CI, 9.32%-56.07%) in the odds of zero seclusion. CONCLUSIONS: This is the first examination of the effect of the IPFQR program on restraint and seclusion, suggesting the program was successful in reducing their use. We did not find support for ownership moderating this effect. Additional research is needed to understand mechanisms of response and the impact of the program on nontargeted aspects of quality.

Consumers' Suggestions for Improving the Mental Healthcare System: Options, Autonomy, and Respect.

While the mental healthcare-consumer voice has gained in legitimacy and perceived value, policy initiatives and system improvements still lack input from consumers. This study explores consumers' suggestions for improving the mental healthcare system. Participants (N = 46) were conveniently recruited and responded to an online survey asking: "What are your suggestions for improving the mental healthcare system?" Eight themes were identified using iterative, inductive and deductive coding. Themes included treatment options, autonomy and empowerment, respect and relationships, medication management, peer support, insurance and access, funding and government support, and treatment environment. Theoretically, there is interdependence among themes where five of the themes are foundational for the three main themes (i.e. treatment options, autonomy and empowerment, respect and relationships). Findings suggest that consumers see the need for improvement in patient-centered care. While access is the focus of much mental healthcare policy discussions, the ultimate goal should be provisioning person-centered mental healthcare.

Harms to Consumers of Inpatient Psychiatric Facilities in the United States: An Analysis of News Articles.

Inpatient psychiatric facilities in the United States lack systematic regulation and monitoring of a variety of patient safety concerns. We conducted a qualitative analysis of 61 news articles to identify common causes and types of harms within inpatient psychiatric facilities, with a focus on physical harm. The news articles reported on patient self-harm, patient-patient violence, and violence between patients and staff, noting that youth, older adults, and veterans were especially vulnerable. Harms occurred throughout the care continuum - at admission, during the inpatient stay, and at discharge - and retaliation towards whistleblowers deterred facility accountability. We recommend 1) addressing staffing shortages, 2) instituting systematic monitoring of critical incidents and the experiences of consumers and staff, 3) improving both inpatient safety and post-discharge community supports, and 4) continued journalistic coverage of harms within inpatient psychiatric facilities.

Neural consequences of post-exertion malaise in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome.

Post exertion malaise is one of the most debilitating aspects of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, yet the neurobiological consequences are largely unexplored. The objective of the study was to determine the neural consequences of acute exercise using functional brain imaging. Fifteen female Myalgic Encephalomyelitis/Chronic Fatigue Syndrome patients and 15 healthy female controls completed 30min of submaximal exercise (70% of peak heart rate) on a cycle ergometer. Symptom assessments (e.g. fatigue, pain, mood) and brain imaging data were collected one week prior to and 24h following exercise. Functional brain images were obtained during performance of: 1) a fatiguing cognitive task - the Paced Auditory Serial Addition Task, 2) a non-fatiguing cognitive task - simple number recognition, and 3) a non-fatiguing motor task - finger tapping. Symptom and exercise data were analyzed using independent samples t-tests. Cognitive performance data were analyzed using mixed-model analysis of variance with repeated measures. Brain responses to fatiguing and non-fatiguing tasks were analyzed using linear mixed effects with cluster-wise (101-voxels) alpha of 0.05. Myalgic Encephalomyelitis/Chronic Fatigue Syndrome patients reported large symptom changes compared to controls (effect size ≥0.8, p<0.05). Patients and controls had similar physiological responses to exercise (p>0.05). However, patients exercised at significantly lower Watts and reported greater exertion and leg muscle pain (p<0.05). For cognitive performance, a significant Group by Time interaction (p<0.05), demonstrated pre- to post-exercise improvements for controls and worsening for patients. Brain responses to finger tapping did not differ between groups at either time point. During number recognition, controls exhibited greater brain activity (p<0.05) in the posterior cingulate cortex, but only for the pre-exercise scan. For the Paced Serial Auditory Addition Task, there was a significant Group by Time interaction (p<0.05) with patients exhibiting increased brain activity from pre- to post-exercise compared to controls bilaterally for inferior and superior parietal and cingulate cortices. Changes in brain activity were significantly related to symptoms for patients (p<0.05). Acute exercise exacerbated symptoms, impaired cognitive performance and affected brain function in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome patients. These converging results, linking symptom exacerbation with brain function, provide objective evidence of the detrimental neurophysiological effects of post-exertion malaise.

Inpatient Psychiatric Care in the United States: Former Patients' Perspectives on Opportunities for Quality Improvement.

Patient-centered care is a salient value expressed by stakeholders, but a commitment to implementing patient-centered care environments lags in the context of inpatient psychiatry. The current study aimed to describe patients' suggestions for improving the quality of inpatient psychiatry. We fielded a national survey online in 2021, in which we asked participants to report their recommendations for care improvement through a free-response box. We used an inductive qualitative approach to synthesize responses into themes. Most responses described negative experiences, with suggested improvements implied as the inverse or absence of the respondent's negative experience. Among 510 participants, we identified 10 themes: personalized care, empathetic connection, communication, whole health approach, humane care, physical safety, respecting patients' rights and autonomy, structural environment, equitable treatment, and continuity of care and systems. To implement the value of patient-centered care, we suggest that those in positions of power prioritize improvement initiatives around these aspects of care that patients find most in need of improvement.

COVID-19 Mitigation Activities in Inpatient Psychiatry Were Associated With Patient-Reported Institutional Betrayal, Changes in Trust, and Fear of Getting Sick.

Institutional betrayal occurs when the institutions that people depend on fail to protect them from harm, which was exemplified by a failure to manage COVID-19 risks. Inpatient psychiatry provides a rich context for which to understand the effects of institutional betrayal, and this is amplified in the context of the COVID-19 pandemic. Using a retrospective cohort design, we administered an online survey to former patients (n = 172) of inpatient psychiatry hospitalized at the height of the COVID-19 pandemic (March 2020 to February 2021) to understand the relationship between facilities' use of COVID-19 mitigation activities (ie, offering or requiring face masks, keeping patients and staff 6 feet apart, access to hand sanitizer, use of telemedicine for clinical consults, and routine cleanliness of the unit) and former patients' reports of institutional betrayal, changes in their trust in mental healthcare providers, fear of getting sick, and having contracted or witnessed someone else contract COVID-19. The quantity of COVID-19 mitigation activities was monotonically negatively associated with the probability of reporting any betrayal, the probability of reduced trust in mental healthcare providers, and the probability of being afraid of getting sick always or most of the time while hospitalized. COVID-19 mitigation activities either directly affected these psychological outcomes, or facilities that engaged in robust mitigation had greater cultures of safety and care quality. Additional qualitative work is needed to understand these mechanisms.

Why Patient-Centered Built Environment Standards Matter More Than Numbers of Beds in Inpatient Psychiatry.

This article canvasses extant literature about values, evidence, and standards for inpatient psychiatry units' design. It then analyzes apparent trade-offs between quality of care and access to care using empirical and ethical lenses. From this analysis, the authors conclude that standards for the built environment of inpatient psychiatric care should align with patient-centeredness, even if a downstream consequence of implementing new patient-centered designs is a reduction in beds, although this secondary outcome is unlikely.

Changes in institution for mental diseases (IMD) ownership status and insurance acceptance over time.

State Medicaid programs are prohibited from using federal dollars to pay institutions for mental diseases (IMDs)-freestanding psychiatric facilities with more than 16 beds. Increasingly, regulatory mechanisms have made payment of treatment in these settings substantially more feasible. This study evaluates if changing financial incentives are associated with increases in for-profit ownership among IMD facilities relative to non-IMD facilities, as well as greater increases in Medicaid acceptance among for-profit IMD facilities relative to for-profit non-IMD facilities. We used data from the 2014-2020 National Mental Health Services Surveys and examined 11 945 facility-years. Relative to non-IMDs, the increase in for-profit ownership among IMDs was 6.6 percentage points greater. The largest proportional change in Medicaid acceptance occurred among for-profit IMD facilities relative to for-profit non-IMDs (18.5 percentage points). Existing research is mixed on the quality of inpatient and residential psychiatric care provided in for-profit vs nonprofit and public facilities, as well as in IMD relative to non-IMD facilities. As payment policy increasingly incentivizes for-profit facilities to enter the psychiatric care space, we should be mindful of the impact of these decisions on patient safety.

Building Community and Identity Online: A Content Analysis of Highly Viewed #Autism TikTok Videos.

Background: TikTok is a popular social media site for connecting with others online where many users also access and share health-related information. Previous studies have characterized information shared about specific disabilities on TikTok, but descriptions of autism-related content are lacking. Understanding the information shared about autism on TikTok is important to understanding health communication in this space, the lived experiences of autistic people, and the role that social media platforms play in building community through connection, understanding, and inclusion. Methods: We used an open-source data scraper to identify and download videos with at least 1 million views and that used the hashtag #autism from TikTok. Using a joint inductive and deductive approach, we performed a content analysis of videos. We identified six content topics that described video content (e.g., positive social interactions and features of autism), and three categories that described video purpose (e.g., educational, experiential, and observational). We used descriptive statistics to describe characteristics of who was in the TikTok videos. Results: We analyzed n = 678 videos. The most common content topic of TikTok videos was features of autism (39.7%), followed by marginalization (25.4%). Most videos were categorized as experiential (61.4%) or observational (31.4%) rather than educational (7.2%). Approximately 65.5% of videos featured an autistic adult and 22.6% featured an autistic child. Among videos featuring an autistic person (n = 594), most autistic people were perceived to be White (87.0%) with similar numbers of feminine (52.9%) and masculine (44.8%) presenting autistic people. Conclusions: Highly viewed #autism TikTok videos primarily share autistic people's individual experiences rather than providing general education about autism. However, autistic Black, Indigenous, and people of color may have difficulty finding others that represent them along both disability and racial dimensions. Future research should investigate autistic people's motivations for using TikTok, and how #autism content shapes social discourse about autism.

What was the purpose of this study?: We wanted to describe information about autism that is highly viewed on TikTok to better understand what people see, hear, and learn about autism online. Autism content on TikTok can help autistic people find others with similar experiences and build community and can shape the way nonautistic people view and interact with autistic people. What did the researchers do?: We downloaded videos from TikTok that used the hashtag #autism and had at least 1 million views. We watched the videos and assigned each video a content topic and a category. Content topics described the content of the video and categories described the purpose of the video. What were the results of the study?: We included 678 videos grouped into six content topics: (1) features of autism, which included videos about restrictive and repetitive behaviors, social and communication differences, associated core experiences, and talents; (2) marginalization, which included videos about lack of access, stigma and misconceptions, and inspiration porn; (3) supports, which included accommodations, services and interventions, and caregiving; (4) positive social interactions; (5) daily life; and (6) miscellaneous/other.The most common content topic was features of autism (39.7%), followed by marginalization (25.4%). The least common content topic was positive social interactions (5.2%). The most common category of videos was experiential (61.4%), followed by observational (31.4%) and educational (7.2%). More than half of the videos included an autistic adult, and about a quarter included an autistic child. Among the videos that included an autistic person, most autistic people were perceived to be White, and there were similar numbers of masculine and feminine-presenting autistic people. What do these findings add to what was already known?: We know that many autistic people like to communicate online and use social media. These findings show that most of the content about autism on TikTok involves autistic people sharing their life experiences instead of providing "facts" or education about autism. Because autistic people from diverse backgrounds were less often present in videos, these individuals may have difficulty connecting with each other on TikTok. What are potential weaknesses in this study?: We did not download TikTok videos while logged into a user account, so the videos we included may be different than the videos shown to an individual user who searches #autism. The way that we categorized videos may have been different from how others would have done so. We did not include less-viewed videos in the study, which could have had different content topics. Our perceptions of the gender, race, and ethnicity of people in videos may not reflect how they would self-identify. How will these findings help autistic adults now or in the future?: These findings may be helpful for autistic adults who are looking for online community building with other autistic people. Because many autistic people shared their lived experiences, these findings may promote understanding and acceptance of autistic people by nonautistic people.

Complaints, Restraint, and Seclusion in Massachusetts Inpatient Psychiatric Facilities, 2008-2018.

There has been limited research on the quality of inpatient psychiatry, yet policies to expand access have increased, such as the use of Medicaid Section 1115 waivers for treatment in "Institutions for Mental Disease" (IMD). Using data from public records requests, we evaluated complaints, restraint, and seclusion from inpatient psychiatric facilities in Massachusetts occurring from 2008 to 2018, and compared differences in the rates of these events by IMD status. There were 17,962 total complaints, with 48.9% related to safety and 19.9% related to abuse (sexual, physical, verbal), and 92,670 episodes of restraint and seclusion. On average, for every 30 census days in a given facility, restraint, and seclusion occurred 7.47 and 1.81 times, respectively, and a complaint was filed 0.94 times. IMDs had 47.8%, 68.3%, 276.9%, 284.8%, 183.6%, and 236.1% greater rates of restraint, seclusion, overall complaints, substantiated complaints, safety-related complaints, and abuse-related complaints, respectively, compared to non-IMDs. This is the first known study to describe complaints from United States inpatient psychiatric facilities. Policies should strengthen the implementation of patients' rights and patient-centeredness, as well as external critical-incident-reporting systems.

Patient-centered inpatient psychiatry is associated with outcomes, ownership, and national quality measures.

Following discharge from inpatient psychiatry, patients experience elevated suicide risk, unplanned readmission, and lack of outpatient follow-up visits. These negative outcomes might relate to patient-centered care (PCC) experiences while hospitalized. We surveyed 739 former patients of inpatient psychiatric settings to understand the relationship between PCC and changes in patients' trust, willingness to engage in care, and self-reported 30-day follow-up visits. We also linked PCC measures to facility-level quality measures in the Inpatient Psychiatric Facility Quality Reporting program. Relative to patients discharged from facilities in the top quartile of PCC, those discharged from facilities in the bottom quartile were more likely to experience reduced trust (predicted probability [PP] = 0.77 vs 0.46; P < .001), reduced willingness to go to the hospital voluntarily (PP = 0.99 vs 0.01; P < .001), and a lower likelihood of a 30-day follow-up (PP = 0.71 vs 0.92; P < .001). PCC was lower among patients discharged from for-profits, was positively associated with facility-level quality measures of 7- and 30-day follow-up and medication continuation, and was inversely associated with restraint use. Findings underscore the need to introduce systematic measurement and improvement of PCC in this setting.

Key person-centered care domains for residential substance use disorder treatment facilities: former clients' perspectives.

BACKGROUND: While person-centered care (PCC) includes multiple domains, residential substance use disorder (SUD) treatment clients may value certain domains over others. We sought to identify the PCC domains most valued by former residential SUD treatment clients. We also sought to explore conceptual distinctions between potential theoretical PCC subdomains. METHODS: We distributed an online survey via social media to a national convenience sample of former residential SUD treatment clients. Respondents were presented with ten PCC domains in an online survey: (a) access to evidence-based care; (b) integration of care; (c) diversity/respect for other cultures; (d) individualization of care; (e) emotional support; (f) family involvement in treatment; (g) transitional services; (h) aftercare; (i) physical comfort; and (j) information provision. Respondents were asked to select up to two domains they deemed most important to their residential SUD treatment experience. We used descriptive statistics to identify response frequencies and logistic regression to predict relationships between selected domains and respondents' race, gender, relationship status, parenting status, and housing stability. RESULTS: Our final sample included 435 former residential SUD treatment clients. Diversity and respect for different cultures was the most frequently selected domain (29%), followed by integration of care (26%), emotional support (26%), and individualization of care (26%). Provision of information was the least frequently chosen domain (3%). Race and ethnicity were not predictive of selecting respect for diversity. Also, parental status, relationship status and gender were not predictive of selecting family integration. Employment and housing status were not predictive of selecting transitional services. CONCLUSIONS: While residential SUD treatment facilities should seek to implement PCC across all domains, our results suggest facilities should prioritize (a) operationalizing diversity, (b) integration of care, and (c) emotional support. Significant heterogeneity exists regarding PCC domains deemed most important to clients. PCC domains valued by clients cannot be easily predicted based on client demographics.

Operationalizing person-centered care in residential substance use disorder treatment.

INTRODUCTION: Person-centered care (PCC) is an ethical imperative with eight domains, but operation of some PCC domains in substance use disorder (SUD) treatment has been underexplored. OBJECTIVE: We sought to identify strategies for operationalizing eight PCC domains in SUD treatment facilities and themes across these strategies. METHODS: We recruited 36 clients and staff from a large publicly funded behavioral health system for individual, semi-structured qualitative interviews. Interviews explored preferences and care experiences for each PCC domain. We analyzed data using iterative categorization, identifying specific operationalization strategies and themes across operationalization strategies within each domain. RESULTS: PCC operationalization themes for residential SUD treatment included addressing social vulnerability of clients (e.g., through assistance with housing and navigation of criminal/legal systems), involving peer support specialists (e.g., to provide emotional support and aid transition out of care), supporting the client's family throughout treatment (e.g., providing progress updates; increasing visitation opportunities in residential treatment), and facilitating patient choice within each domain (e.g., treatment type; housing type; roommate preferences in residential treatment.). DISCUSSION & CONCLUSION: Some PCC operationalization strategies are unique to SUD treatment. Several PCC operationalization strategies applied to multiple domains, suggesting conceptual overlap between domains.

Effects of the CMS' Public Reporting Program for Inpatient Psychiatric Facilities on Targeted and Nontargeted Safety: Differences Between For-Profits and Nonprofits.

The Centers for Medicare and Medicaid Services implemented the Inpatient Psychiatric Facility Quality Reporting Program in 2012, which publicly reports facilities' performance on restraint and seclusion (R-S) measures. Using data from Massachusetts, we examined whether nonprofits and for-profits responded differently to the program on targeted indicators, and if the program had a differential spillover effect on nontargeted indicators of quality by ownership. Episodes of R-S (targeted), complaints (nontargeted), and discharges were obtained for 2008-2017 through public records requests to the Commonwealth of Massachusetts. Using difference-in-differences estimators, we found no differential changes in R-S between for-profits and nonprofits. However, for-profits had larger increases in overall complaints, safety-related complaints, abuse-related complaints, and R-S-related complaints compared with nonprofits. This is the first study to examine the effects of a national public reporting program among psychiatric facilities on nontargeted measures. Researchers and policymakers should further scrutinize intended and unintended consequences of performance-reporting programs.

Plant-Mediated Behavioural Avoidance of a Weevil Towards Its Biological Control Agent.

New Zealand pastures largely comprising Lolium ryegrass species (Poales: Poaceae) are worth $19.6B and are subject to major pest impacts. A very severe pest is the Argentine stem weevil Listronotus bonariensis (Kuschel) (Coleoptera: Curculionidae). This has been previously suppressed by the importation biological control agent, Microctonus hyperodae Loan (Hymenoptera: Braconidae). However, this suppression has recently declined and is subject to investigation. It has been hypothesised that grass type influences the parasitism avoidance behaviour by the weevil and thus parasitism rates. This study explored the hypothesis using three common pasture grasses: a diploid Lolium perenne x Lolium multiflorum hybrid ryegrass (cv. Manawa), a tetraploid Italian ryegrass L. multiflorum Lam. (cv. Tama), and a diploid perennial ryegrass L. perenne L. (cv. Samson). The described laboratory-based microcosm methodology determined the extent of weevil avoidance behaviour on each of these three grasses when subjected to the parasitoid. Such reaction was gauged by the extent of reduced weevil on-plant presence and feeding compared to the control populations. In the absence of the parasitoid, the hybrid cv. Manawa ryegrass is as highly favoured by the weevil as the tetraploid cv. Tama. On diploid cv. Samson, feeding is considerably less. In the presence of the parasitoid, weevils on the tetraploid cv. Tama plants showed little avoidance activity in response to the parasitoid and it can be argued that the benefits of staying on this plant outweighed the possibility of parasitism. Conversely and surprisingly, in the parasitoid's presence, weevils on diploid cv. Manawa showed very strong avoidance behaviour leading to levels of exposure similar to those found on the less-preferred diploid cv. Samson. These findings reflect how weevil parasitism rates have declined in most Lolium grasses, particularly diploids, since the 1990s, but not in the tetraploid L. multiflorum. This contribution supports the hypothesis that the decline in weevil parasitism rates has been the result of rapid evolution arising from parasitoid-induced selection pressure and the countervailing effect of the nutritional quality of the host plants.

Youths' and Young Adults' Experiences of Police Involvement During Initiation of Involuntary Psychiatric Holds and Transport.

Over the past decade, police involvement in behavioral health crisis response has generated concern and controversy. Despite the salience and timeliness of this topic, the literature on service user experiences of interactions with officers is small and studies of youths and young adults are nonexistent. The authors aimed to investigate youths' and young adults' experiences of police involvement in involuntary psychiatric hold initiation and transport. In-depth interviews were conducted with 40 participants (ages 16-27) who had experienced an involuntary hold; the 28 participants who reported police involvement are the focus of this analysis. Data were inductively coded, and codes were grouped into larger themes. A majority of participants reported negative experiences; major themes characterizing negative encounters were the framing of distress as criminal or of intervention as disciplinary rather than therapeutic, perceived aggression and callousness from police officers, and poor communication. The authors also characterized the positive experiences of officer involvement reported by a minority of participants and youths' perspectives on the degree of control officers could exert over initiation and transport decisions. Findings help center the voices of youths and young adults with mental health challenges and raise important questions about contemporary policies regarding police involvement in crisis response and, more broadly, about coercive responses to distress or emotional crisis.
