RESUMO
The pear psyllids (Cacopsylla spp.; Psylloidea) comprise ~24 species of sap-feeding insects distributed in Europe, temperate Asia, and (as introductions) in the Americas. These pear-specialized insects are among the most damaging and difficult to control pests in orchards. Biological control increasingly is being used to replace or partially replace insecticidal management of pear psyllids. Many key natural enemies of pear psyllids regularly occur in non-orchard habitats on native plants. The presence of beneficial species both in orchard and non-orchard habitats (here referred to as "spillover") has prompted suggestions that native plants and their associated psyllids should be conserved as alternative resources for natural enemies of pear psyllids. The expectation is that the natural enemies will move from those habitats into psyllid-infested orchards. This review shows that psyllids in native habitats are important resources for several key predators and parasitoids of pear psyllids. These resources are critical enough that some beneficials exhibit an almost nomadic existence as they move between plant species, tracking the seasonal appearance and disappearance of psyllid species. In contrast, other natural enemies show minimal or no spillover between orchard and non-orchard habitats, which likely is evidence that they exhibit limited movement at best between orchard and non-orchard habitats. To show conclusively that spillover also indicates that a beneficial species disperses between native habitats and orchards requires difficult research on insect movement. This review concludes with a brief discussion of these difficulties and possible solutions.
RESUMO
Background/objectives: Surgical populations and particularly injury survivors often present with complex trauma that elevates their risk for prolonged opioid use and misuse. Changes in opioid prescribing guidelines during the past several years have yielded mixed results for pain management after trauma, with a limiting factor being the heterogeneity of clinical populations and treatment needs in individuals receiving opioids. The present analysis illuminates this gap between clinical guidelines and clinical practice through qualitative feedback from hospital trauma providers and unit staff members regarding current opioid prescribing guidelines and practices in the setting of traumatic injury. Methods: The parent study aimed to implement a pilot screening tool for opioid misuse in four level I and II trauma hospitals throughout Wisconsin. As part of the parent study, focus groups were conducted at each study site to explore the facilitators and barriers of implementing a novel screening tool, as well as to examine the current opioid prescribing guidelines, trainings, and resources available for trauma and acute care providers. Focus group transcripts were independently coded and analyzed using a modified grounded theory approach to identify themes related to the facilitators and barriers of opioid prescribing guidelines in trauma and acute care. Results: Three major themes were identified as impactful to opioid-related prescribing and care provided in the setting of traumatic injury; these include (1) acute treatment strategies; (2) patient interactions surrounding pain management; and (3) the multifactorial nature of trauma on pain management approaches. Conclusion: Providers and staff at four Wisconsin trauma centers called for trauma-specific opioid prescribing guidelines in the setting of trauma and acute care. The ubiquitous prescription of opioids and challenges in long-term pain management in these settings necessitate additional community-integrated research to inform development of federal guidelines. Level of evidence: Therapeutic/care management, level V.
RESUMO
This article reports qualitative outcomes from a randomized controlled trial comparing eight weeks of cognitive-behavioral group therapy for chronic pain (CBT-CP) and mindfulness-based group therapy (MBT) in individuals with chronic low back pain (CLBP). Approximately 10 months post-treatment, 108 participants completed structured qualitative interviews to express how the study treatment affected their life or health. Responses were qualitatively analyzed to generate a set of themes and subthemes, with between-groups comparisons to evaluate differences (if any) in treatment-response between MBT and CBT-CP. A majority of participants (n = 88, 81.5%) across both groups reflected positively on the study intervention and outcomes, identifying benefits in pain management (31.5%), meditation and mindfulness skills (25.9%), and relaxation skills (22.2%). Perceived benefits varied widely, suggesting no one intervention may be ideal for CLBP. Future research should examine tailoring interventions to target diverse clinical presentations to achieve optimal outcomes.
RESUMO
PURPOSE: The aim of this study was to evaluate the imaging capabilities of Butterfly iQ with conventional ophthalmic (piezoelectric) ultrasound (COU) for ophthalmic imaging. METHODS: Custom phantom molds were designed and imaged with Butterfly iQ and COU to compare spatial resolution capabilities. To evaluate the clinical imaging performance of Butterfly iQ and COU, a survey containing pathological conditions from human subjects, imaged with both Butterfly iQ and COU probes, was given to three retina specialists and graded on image detail, resolution, quality, and diagnostic confidence on a ten-point Likert scale. Kruskal-Wallis analysis was performed for survey responses. RESULTS: Butterfly iQ and COU had comparable capabilities for imaging small axial and lateral phantom features (down to 0.1 mm) of high and low acoustic reflectivity. One of three retina specialists demonstrated a statistically significant preference for COU related to resolution, detail, and diagnostic confidence, but the remaining graders showed no significant preference for Butterfly iQ or COU across all sample images presented. CONCLUSION: The emergence of portable ultrasound probes offers an affordable alternative to COU technologies with comparable qualitative imaging resolution down to 0.1 mm. These findings suggest the value to further study the use of portable ultrasound systems and their utility in routine eye care.

Pear psylla, Cacopsylla pyricola (Foerster) (Hemiptera: Psyllidae), occurs as 2 seasonal morphotypes. Summerforms occur on pear (Pyrus communis L.; Rosales: Rosaceae) where they are a significant pest. The larger and darker winterform morphotype develops in response to shortening daylengths and begins winter in reproductive diapause characterized by the absence of ovarian development. Diapausing winterforms often leave pear to overwinter on coniferous shelter plants and then return to pear in late winter and early spring to begin depositing the eggs that produce the first summerform generation. Cacopsylla pyricola adults are attracted to the color of foliage most of the year, but little is known about the role of plant volatiles in host finding and in seasonal dispersal between host and shelter plants by the psyllid. We used a Y-tube olfactometer and choice assays to investigate the response by C. pyricola adults to volatiles emitted by pear and an evergreen tree (cypress) often used as a shelter plant by wintering C. pyricola. Attraction to pear and cypress volatiles varied by season, tree phenology, and psyllid physiology. Cacopsylla pyricola were attracted to cypress volatiles and preferred to settle on cypress shoots during winter and early spring but then shifted to a marked preference for the pear developmental host in late spring and summer. Female C. pyricola exhibited stronger responses to pear volatiles than did males. Our study is the first to show that plant volatiles have a role in host finding by C. pyricola and provides a foundation for research on chemical ecology and management of C. pyricola.

Background: As the opioid crisis continues to affect communities across the United States, new interventions for screening and prevention are needed to mitigate its impact. Mental health diagnoses have been identified as a risk factor for opioid misuse, and surgical populations and injury survivors are at high risk for prolonged opioid use and misuse. This study investigated the implementation of a novel opioid risk screening tool that incorporated putative risk factors from a recent study in four trauma units across Wisconsin. Method: The screening tool was implemented across a 6-month period at four sites. Data was collected via monthly meeting notes and "Plan, Do, Study, Act" (PDSA) forms. Following implementation, focus groups reflected on the facilitators and barriers to implementation. Meeting notes, PDSA forms, and focus group data were analyzed using the consolidated framework for implementation research, followed by thematic analyses, to generate themes surrounding the facilitators and barriers to implementing an opioid misuse screener. Results: Implementation facilitators included ensuring patient understanding of the screener, minimizing staff burden from screening, and educating staff to encourage engagement. Barriers included infrastructure limitations that prevented seamless administration of the screener within current workflows, overlap of the screener with existing measures, and lack of guidance surrounding treatment options corresponding to risk. Recommended solutions to address barriers include careful timing of screener administration, accommodating workflows, integration of the screening tool within the electronic health record, and evidence-based interventions guided by screener results. Conclusion: Four trauma centers across Wisconsin successfully implemented a pilot opioid misuse screening tool. Trauma providers and unit staff members believe that this tool would be a beneficial addition to their repertoire if their recommendations were adopted. Future research should refine opioid misuse risk factors and ensure screening items are well-validated with psychometric research supporting treatment responses to screener-indicated risk categories.
As the opioid crisis continues to affect communities across the United States, new interventions for early screening and prevention are needed to minimize the related harms. Prior research has identified risk factors associated with opioid misuse among a trauma surgical patient population, with the highest risk associated with distress-related posttraumatic stress disorder symptoms. A pilot screening tool was created based on this prior research, which was then administered at four trauma surgical units across the state of Wisconsin. Each of the four trauma units successfully implemented the pilot screening tool, and each identified a number of facilitators and barriers to the implementation process. Recommendations for improvement of the implementation process were also gathered. If their recommended changes were to be adopted, trauma providers and trauma unit staff members believed that such a screener for opioid misuse would be a beneficial addition to their current workflow among traumatic injury patients. Future research should refine opioid misuse risk factors and develop a psychometrically sound, validated screener to detect varying levels of risk and tailor treatment approaches based on a patient's risk score. Additionally, future research in the field of opioid misuse prevention should prioritize the recruitment of a more diverse population to support the translation of study findings across populations.
RESUMO
RATIONALE: Psychedelic-assisted psychotherapy (PAP) has emerged as a potential treatment for a variety of mental health conditions, including substance use disorders and depression. Current models of PAP emphasize the importance of psychotherapeutic support before, during, and after ingestion of a psychedelic to maximize safety and clinical benefit. Despite this ubiquitous assumption, there has been surprisingly little empirical investigation of the "psychotherapy" in PAP, leaving critical questions about the necessary and sufficient components of PAP unanswered. OBJECTIVES: As clinical trials for psychedelic compounds continue the transition from safety- and feasibility-testing to evaluating efficacy, the role of the accompanying psychotherapy must be better understood to enhance scientific understanding of the mechanisms underlying therapeutic change, optimize clinical outcomes, and inform cost-effectiveness. RESULTS: The present paper first reviews the current status of psychotherapy in the PAP literature, starting with recent debates regarding "psychotherapy" versus "psychological support" and then overviewing published clinical trial psychotherapy models and putative models informed by theory. We then delineate lessons that PAP researchers can leverage from traditional psychotherapy research regarding standardizing treatments (e.g., publish treatment manuals, establish eligibility criteria for providers), identifying mechanisms of change (e.g., measure established mechanisms in psychotherapy), and optimizing clinical trial designs (e.g., consider dismantling studies, comparative efficacy trials, and cross-lagged panel designs). Throughout this review, the need for increased research into the psychotherapeutic components of treatment in PAP is underscored. CONCLUSIONS: PAP is a distinct, integrative, and transdisciplinary intervention. Future research designs should consider transdisciplinary research methodologies to identify best practices and inform federal guidelines for PAP administration.
