RESUMEN

Treatment outcomes are strongly influenced by expectations, as evidenced by the placebo effect. Meta-analyses of clinical trials reveal that placebo effects are strongest in pain, indicating that psychosocial factors directly influence pain. In this review, I focus on the neural and psychological mechanisms by which instructions, learning, and expectations shape subjective pain. I address new experimental designs that help researchers tease apart the impact of these distinct processes and evaluate the evidence regarding the neural mechanisms by which these cognitive factors shape subjective pain. Studies reveal that expectations modulate pain through parallel circuits that include both pain-specific and domain-general circuits such as those involved in affect and learning. I then review how expectations, learning, and verbal instructions impact clinical outcomes, including placebo analgesia and responses to pharmacological treatments, and discuss implications for future work.

RESUMEN

Fear learning allows us to identify and anticipate aversive events and adapt our behavior accordingly. This is often thought to rely on associative learning mechanisms where an initially neutral conditioned stimulus (CS) is repeatedly paired with an aversive unconditioned stimulus (US), eventually leading to the CS also being perceived as aversive and threatening. Importantly, however, humans also show verbal fear learning. Namely, they have the ability to change their responses to stimuli rapidly through verbal instructions about CS-US pairings. Past research on the link between experience-based and verbal fear learning indicated that verbal instructions about a reversal of CS-US pairings can fully override the effects of previously experienced CS-US pairings, as measured through fear ratings, skin conductance, and fear-potentiated startle. However, it remains an open question whether such instructions can also annul learned CS representations in the brain. Here, we used a fear reversal paradigm (female and male participants) in conjunction with representational similarity analysis of fMRI data to test whether verbal instructions fully override the effects of experienced CS-US pairings in fear-related brain regions or not. Previous research suggests that only the right amygdala should show lingering representations of previously experienced threat ("pavlovian trace"). Unexpectedly, we found evidence for the residual effect of prior CS-US experience to be much more widespread than anticipated, in the amygdala but also cortical regions like the dorsal anterior cingulate or dorsolateral prefrontal cortex. This finding shines a new light on the interaction of different fear learning mechanisms, at times with unexpected consequences.SIGNIFICANCE STATEMENT Humans are able to learn about aversive stimuli both from experience (i.e., repeated pairings of conditioned stimulus (CS) and unconditioned stimulus (US; pavlovian conditioning), and from verbal instructions about stimulus pairings. Understanding how experience-based and verbal learning processes interact is key for understanding the cognitive and neural underpinnings of fear learning. We tested whether prior aversive experiences (CS-US pairings) affected subsequent verbal learning, searching for lingering threat signals after verbal instructions reversed a CS from being threatening to being safe. While past research suggested such threat signals can only be found in the amygdala, we found evidence to be much more widespread, including the medial and lateral PFC. This highlights how experience-based and verbal learning processes interact to support adaptive behavior.

RESUMEN

Alpha oscillations are known to play a central role in several higher-order cognitive functions, especially selective attention, working memory, semantic memory, and creative thinking. Nonetheless, we still know very little about the role of alpha in the generation of more remote semantic associations, which is key to creative and semantic cognition. Furthermore, it remains unclear how these oscillations are shaped by the intention to "be creative," which is the case in most creativity tasks. We aimed to address these gaps in two experiments. In Experiment 1, we compared alpha oscillatory activity (using a method which distinguishes genuine oscillatory activity from transient events) during the generation of free associations which were more vs. less distant from a given concept. In Experiment 2, we replicated these findings and also compared alpha oscillatory activity when people were generating free associations versus associations with the instruction to be creative (i.e. goal-directed). We found that alpha was consistently higher during the generation of more distant semantic associations, in both experiments. This effect was widespread, involving areas in both left and right hemispheres. Importantly, the instruction to be creative seems to increase alpha phase synchronisation from left to right temporal brain areas, suggesting that intention to be creative changed the flux of information in the brain, likely reflecting an increase in top-down control of semantic search processes. We conclude that goal-directed generation of remote associations relies on top-down mechanisms compared to when associations are freely generated.

RESUMEN

BACKGROUND: Sleep medicines should be prescribed cautiously, accompanied by instructions that ensure appropriate use and reduce risks. This is especially important for older adults, for whom many of these medicines are classified as potentially inappropriate medicines. METHODS: We investigated the use and appropriateness of dosing instructions for sleep medicines (described in the Finnish National Current Care Guideline for Insomnia) prescribed for older adults (≥75 years) and dispensed with instruction label in pharmacies. The retrospective reimbursement register data for year 2020 by the Social Insurance Institution of Finland was used as the data source (1,080,843 purchases by 143,886 individuals of which 565,228 purchases were pharmacy dispenses). The appropriateness of the pharmacy dosing instructions containing keyword(s) referring to insomnia treatment was examined according to the prescribed dose, time of intake, frequency of use, and warnings/remarks. A random sample of 1000 instructions was used to manually analyze the phrasing and appropriateness. OUTCOMES: We focused our analysis on 58.1% (328,285 purchases by 87,396 individuals) of the pharmacy dispenses, which contained dosing instructions referring insomnia treatment. Of these, zopiclone and mirtazapine were the most prescribed drugs (134,631 and 112,463 purchases, respectively). Dose and time of intake were specified in most of the instructions (98.4% and 83.4%, respectively), whereas frequency of use was specified in 57.3%. A small percentage of the instructions included warnings/remarks (2.8%). Overall, only 2.1% of the instructions contained information about a single dose, time of intake, temporary use, and warnings/remarks and were thus defined as sufficient. Notably, 47.7% (n = 515,615) of all the purchases in our dataset were dispensed via automated multi-dose dispensing systems, which is aimed for long-term treatment. INTERPRETATION: It is common to prescribe sleep medicines for older adults without appropriate dosing instructions, particularly excluding warnings against long-term, regular use. Actions to change the current prescribing practices are warranted.

RESUMEN

BACKGROUND: Neurological disorders have had a substantial rise the last three decades, imposing substantial burdens on both patients and healthcare costs. Consequently, the demand for high-quality research has become crucial for exploring effective treatment options. However, current neurology research has some limitations in terms of transparency, reproducibility, and reporting bias. The adoption of reporting guidelines (RGs) and trial registration policies has been proven to address these issues and improve research quality in other medical disciplines. It is unclear the extent to which these policies are being endorsed by neurology journals. Therefore, our study aims to evaluate the publishing policies of top neurology journals regarding RGs and trial registration. METHODS: For this cross-sectional study, neurology journals were identified using the 2021 Scopus CiteScore Tool. The top 100 journals were listed and screened for eligibility for our study. In a masked, duplicate fashion, investigators extracted data on journal characteristics, policies on RGs, and policies on trial registration using information from each journal's Instruction for Authors webpage. Additionally, investigators contacted journal editors to ensure information was current and accurate. No human participants were involved in this study. Our data collection and analyses were performed from December 14, 2022, to January 9, 2023. RESULTS: Of the 356 neurology journals identified, the top 100 were included into our sample. The five-year impact of these journals ranged from 50.844 to 2.226 (mean [SD], 7.82 [7.01]). Twenty-five (25.0%) journals did not require or recommend a single RG within their Instructions for Authors webpage, and a third (33.0%) did not require or recommend clinical trial registration. The most frequently mentioned RGs were CONSORT (64.6%), PRISMA (52.5%), and ARRIVE (53.1%). The least mentioned RG was QUOROM (1.0%), followed by MOOSE (9.0%), and SQUIRE (17.9%). CONCLUSIONS: While many top neurology journals endorse the use of RGs and trial registries, there are still areas where their adoption can be improved. Addressing these shortcomings leads to further advancements in the field of neurology, resulting in higher-quality research and better outcomes for patients.

RESUMEN

Geriatric patients compose a growing proportion of the dermatologic surgical population. Dermatologists and dermatologic surgeons should be cognizant of the unique physiologic considerations that accompany this group to deliver highly effective care. The purpose of this article is to discuss the unique preoperative, intraoperative, and postoperative considerations geriatric patients present with to provide goal-concordant care. Preoperative considerations include medication optimization and anxiolysis. Intraoperative considerations such as fall-risk assessment and prevention, sundowning, familial support, and pharmacologic interactions will be discussed. Lastly, effective methods for optimizing post-operative wound care, home care, and follow up are reviewed.

RESUMEN

OBJECTIVES: To examine the effectiveness of explicit task (ie, equal, motor or cognitive) prioritization during dual tasking (DT) in adults with neurologic and neurocognitive disorders (stroke, Parkinson disease [PD], multiple sclerosis, dementia, Alzheimer disease, and mild cognitive impairment). DATA SOURCE: A systematic search in 4 databases (PubMed, Web of Science, Embase, and Cochrane Central) yielded 1138 unique studies published up to 2023. STUDY SELECTION: Forty-one experimental studies were selected that assessed the effect of explicit prioritization instructions on both motor and cognitive performance during dual-tasks related to standing and walking in selected populations. Primary outcome measures were walking speed and response accuracy. Availability of data allowed us to perform a meta-analysis on 27 of the 41 articles by using inverse variance with a random effects model. DATA EXTRACTION: The data including design, subject characteristics, motor and cognitive tasks, prioritization, motor and cognitive outcomes, instructions, and key findings were extracted. Two assessors rated the selected studies for risk of bias and quality using the Quality Assessment Tools of the National Institutes of Health. DATA SYNTHESIS: This study examined 1535 adults who were asked to perform motor-cognitive DT in standing or walking, including 381 adults with stroke, 526 with PD, 617 with multiple sclerosis, 10 with dementia, 9 with Alzheimer disease, and 8 with mild cognitive impairment. During all prioritization instructions, participants slowed down during DT (standardized mean difference (SMD)equal=0.43; SMDmotor=0.78; SMDcognitive=0.69, P<.03) while maintaining similar response accuracy (SMDequal=0.12; SMDmotor=0.23; SMDcognitive=-.01, P>.05). However, considerable between-group heterogeneity was observed resulting in different motor and cognitive responses between pathologies. CONCLUSION: Motor prioritization was achieved in adults with PD and stroke, unlike adults with neurocognitive disorders who were negatively affected by any type DT prioritizing. The reported within-group heterogeneity revealed that effects of explicit task prioritization are dependent on motor and cognitive task complexity, and the type of instructions. Recommendations are provided to ensure accurate use of instructions during DT paradigms.

RESUMEN

PURPOSE: Obstructive sleep apnea (OSA) is the most common sleep-disordered breathing. The high prevalence makes its diagnosis a priority. To perform type III sleep studies, patients usually receive instructions from a technician. The switch to instructions through a video could save professionals time and make OSA diagnosis more accessible. This study aimed to compare the technical quality of type III sleep studies when instructions are provided by face-to-face technical teaching or via video. METHODS: One hundred consecutive patients aged ≥ 18 years with suspected OSA were randomly assigned to receive device placement instructions in person by a technician or through video (50 in each group). The overall quality of the sleep studies was analyzed by determining the number of technically invalid studies. The recording quality of four sensors (pulse oximeter, nasal flow cannula, chest, and abdominal bands) was evaluated by checking for signal artifacts. RESULTS: The majority (86%) of the studies were valid. 20% of the studies in the face-to-face group and 8% of the studies in the video-instruction group were technically invalid, but no statistically significant difference was found (p = 0.148). The quality of the oximetry signal was better in those who received video instructions (p = 0.05). Regarding the recording quality of the remaining sensors, no significant differences were found. CONCLUSIONS: Type III sleep studies with previous explanation through a video are as effective as those with an explanation performed by a technician, with associated advantages, without increased errors. The quality of the oximetry signal was better in the video group, a critical signal for OSA diagnosis.

RESUMEN

INTRODUCTION: Traumatic brain injury (TBI) results in 2.5 million emergency department (ED) visits per year in the US, with mild traumatic brain injury (mTBI) accounting for 90% of cases. There is considerable evidence that many experience chronic symptoms months to years later. This population is rarely represented in interventional studies. Management of adult mTBI in the ED has remained unchanged, without consensus of therapeutic options. The aim of this review was to synthesize existing literature of patient-centered ED treatments for adults who sustain an mTBI, and to identify practices that may offer promise. METHODS: A systematic review was conducted using the PubMed and Cochrane databases, while following PRISMA guidelines. Studies describing pediatric patients, moderate to severe TBI, or interventions outside the ED were excluded. Two reviewers independently performed title and abstract screening. A third blinded reviewer resolved discrepancies. The Mixed Methods Appraisal Tool (MMAT) was employed to assess the methodological quality of the studies. RESULTS: Our search strategy generated 1002 unique titles. 95 articles were selected for full-text screening. The 26 articles chosen for full analysis were grouped into one of the following intervention categories: (1) predictive models for Post-Concussion Syndrome (PCS), (2) discharge instructions, (3) pharmaceutical treatment, (4) clinical protocols, and (5) functional assessment. Studies that implemented a predictive PCS model successfully identified patients at highest risk for PCS. Trials implementing discharge related interventions found the use of video discharge instructions, encouragement of daily light exercise or bed rest, and text messaging did not significantly reduce mTBI symptoms. The use of electronic clinical practice guidelines (eCPG) and longer leaves of absence from work following injury reduced symptoms. Ondansetron was shown to reduce nausea in mTBI patients. Studies implementing ED Observation Units found significant declines in inpatient admissions and length of hospital stay. The use of tablet-based tasks was found to be superior to many standard cognitive assessments. CONCLUSION: Validated instruments are available to aid clinicians in identifying patients at risk for PCS or serious cognitive impairment. EDOU management and evidence-based modifications to discharge instructions may improve mTBI outcomes. Additional research is needed to establish the therapeutic value of medications and lifestyle changes for the treatment of mTBI in the ED.

RESUMEN

The purpose of this study was to investigate the instructions for authors of rheumatology journals and analyze their endorsement of reporting guidelines and clinical trial registration. Sixty rheumatology journals were selected by a research librarian and an investigator through the 2021 Scopus CiteScore tool. The instructions for authors' subsection of each journal was assessed to determine endorsement of study design-specific reporting guidelines or clinical trial registration. Descriptive statistics were calculated using R (version 4.2.1) and RStudio. Of the 58 journals analyzed, 34 (34/58; 59%) mentioned the EQUATOR Network: an online compendium of best practice reporting guidelines. The most commonly mentioned reporting guidelines were CONSORT with 44 journals (44/58; 75%), and PRISMA with 35 journals (35/58; 60%). The least mentioned guidelines were QUOROM with 56 journals not mentioning the guideline (56/58; 97%), and SRQR with 53 journals not mentioning the guideline (53/57, 93%). Clinical trial registration was required by 38 journals (38/58; 66%) and recommended by 8 journals (8/58; 14%). Our study found that endorsement of reporting guidelines and clinical trial registration within rheumatology journals was suboptimal with great room for improvement. Endorsement of reporting guidelines have shown to not only mitigate bias, but also improve research methodologies. Therefore, we recommend rheumatology journals broadly expand their endorsement of reporting guidelines and clinical trial registration to improve the quality of evidence they publish.

RESUMEN

INTRODUCTION: Although COVID-19 has entered the endemic phase, individuals infected with COVID-19 are required to adhere to home quarantine measures. By exploring the public's knowledge and attitude towards recommended home quarantine measures, their readiness in containing potential COVID-19 outbreak can be determined. This study aimed to assess the public knowledge and attitude towards home quarantine instructions and their association with history of COVID-19 infections. METHODS: This was a web-based cross-sectional study conducted among the public in Malaysia between August to October 2022. All Malaysian adults over 18 years of age were included. Knowledge on home quarantine instructions and COVID-19 warning signs were measured using "True," "False," or "I'm not sure", while attitude towards home quarantine instructions was measured using a five-point Likert Scale. The questionnaire was initially constructed in English and then translated into the national language, Bahasa Malaysia. Face and content validation were performed. The internal consistency of the questionnaire was found to be satisfactory. RESULTS: 1,036 respondents were analyzed, comprised mostly of females (743, 71.6%) with a history of COVID-19 (673, 64.9%). In the knowledge domain, more than 80% of the respondents answered 9 out of 11 home quarantine instructions statements correctly. 457 (44.1%) were unaware or unsure about the minimum distance of the infected individual's bed from the rest of the occupants in a shared bedroom. The respondents reported relatively weaker knowledge in identifying uncommon warning signs of COVID-19 deterioration, including anuria (162, 44.5%), ingestion problems (191, 52.5%), and immobility (195, 53.6%). In the attitude domain, more than 90% of respondents answered correctly in 8 out of 9 questions. Respondents with a previous history of COVID-19 infections had better knowledge than COVID-19 infection-naïve individuals towards both home quarantine instructions and COVID-19 warning signs. CONCLUSION: Most respondents had good knowledge and attitude towards home quarantine instructions, with those previously infected with COVID-19 showing greater awareness of uncommon warning signs. However, there was a notable lack of awareness regarding physical distancing within shared rooms, appropriate disinfectant use and mobility limitation within the household. This study highlights the knowledge gaps to be improved in future educational campaigns.

RESUMEN

BACKGROUND: Research on age-progression facial morphing interventions for smoking cessation has not investigated the effect of different instructions for intervention delivery. The objective of this pilot study was to investigate the influence of two instruction types used to deliver the intervention on efficacy of the intervention. METHOD: Women were recruited and randomly allocated to an age-progression intervention session with (i) neutral instructions; (ii) instructions designed to reassure; or (iii) a condition that controlled for participant engagement ("control"). The conditions were delivered in a one-time procedure, after which primary (quitting intentions) and secondary (cigarettes/week, quit attempts) outcomes were measured immediately post-intervention, and at 1 and 3 months. RESULTS: Seventy-two women (M = 25.7; SD = 0.9) were recruited and randomly allocated to condition (Neutral n = 27, Reassuring n = 22, Control n = 23). Quitting intentions were higher in the Reassuring versus Control arm (3 months post-intervention, F = 4.37, p = 0.016, 95% CI [0.231, 2.539], eta2 = 0.11); quit attempts were greater in the two intervention arms (58%) versus Control (1-month post-intervention, 15%) (χ2 = 9.83, p < 0.05, OR 1.00 [0.28, 3.63]). CONCLUSIONS: Findings highlight the importance of optimising instructions to enhance intervention efficacy. TRIAL REGISTRATION: clinicaltrials.gov Record: NCT03749382.

RESUMEN

BACKGROUND: Medical research in complementary and alternative medicine (CAM) has increased recently, raising ethical concerns about the moral status of CAM. Medical academic journals are responsible for conducting ethical review (ER) of manuscripts to protect the interests of human subjects and to make ethical results available before deciding to publish. However, there has been no systematic analysis of the ER in CAM journals. This study is aim to evaluate the current status of ethical requirements and compliance in CAM journals. METHODS: This is a cross-sectional study. We reviewed instructions for authors (IFAs) of CAM journals included in the Journal Citation Reports (2021) ( https://jcr.clarivate.com ) for general information and requirements for ER. We also browsed the manuscripts regarding randomized controlled trials published by CAM journals in Q1 and Q2 section from January to June, 2023, to check the actual situation of ethical requirement. Descriptive statistics and Fisher's exact test were used for statistical analysis. RESULTS: 27 journals and 68 manuscripts were ultimately included. 92.6% (25/27) IFAs included keywords of ER, indicating the presence of ethical considerations. However, no specific ER was required for CAM (n = 0). We categorized journals by Geographic origin, JCR section, Year of electronic JCR, Types of studies, % of OA Gold to explore the factors that could influence CAM journals to have certain ethical review policies. The results showed there was no statistical significance in certain ethical review policy in any classification of journals (p > 0.05). All RCT manuscripts included in the study generally met the requirements of the published journals for ethical review. CONCLUSIONS: All IFAs discussed ER, but the content was scattered, unfocused, and there were no specific ER requirements regarding CAM. Although the manuscripts basically met the requirements of the journal, it was not possible to get closer to the process of ER in the manuscript. To ensure full implementation of these policies in the future, CAM journals should require authors to provide more details, or to form a list of items necessary for CAM ethical review.

RESUMEN

OBJECTIVES: EVAR is the preferred treatment modality for patients with an infrarenal abdominal aortic aneurysm with suitable anatomy. Each manufacturer of aortic stentgrafts has specific anatomic requirements. In some patients, it is not possible to adhere to the instructions for use, but alternative treatment is also not possible. In these patients, EVAR can be performed outside instructions for use. METHODS: In this study, all consecutive patients in whom an Endurant II or IIS stentgraft was used between 1 January and 31 December were reviewed. We compared the two patient groups in whom this stentgrafts was used outside and inside instructions for use. Patients with planned adjuvant therapy, for example, chimney procedure or iliac side branches, were excluded. RESULTS: In 74 of 178 (41.6%) patients, the instructions for use were not adhered. The main reason was pathology of the aortic neck. There were more patients with type IA endoleak, this difference was borderline significant (p = .06). There were more patients with limb occlusion in the early postoperative period, but at the end of the follow-up period, the incidence was comparable. Aneurysm-related mortality and all-cause mortality were comparable in both groups. CONCLUSION: In this study, real-life experience with the Endurant II and IIS stentgraft is described. Non-adherence with instructions for use was associated with a higher risk of endoleak type IA (p = .06). In the early postoperative period, there were more patients with limb occlusion; this finding was not observed anymore at the end of the follow-up period.

RESUMEN

BACKGROUND: Discharge instructions are a key form of documentation and patient communication in the time of transition from the emergency department (ED) to home. Discharge instructions are time-consuming and often underprioritized, especially in the ED, leading to discharge delays and possibly impersonal patient instructions. Generative artificial intelligence and large language models (LLMs) offer promising methods of creating high-quality and personalized discharge instructions; however, there exists a gap in understanding patient perspectives of LLM-generated discharge instructions. OBJECTIVE: We aimed to assess the use of LLMs such as ChatGPT in synthesizing accurate and patient-accessible discharge instructions in the ED. METHODS: We synthesized 5 unique, fictional ED encounters to emulate real ED encounters that included a diverse set of clinician history, physical notes, and nursing notes. These were passed to GPT-4 in Azure OpenAI Service (Microsoft) to generate LLM-generated discharge instructions. Standard discharge instructions were also generated for each of the 5 unique ED encounters. All GPT-generated and standard discharge instructions were then formatted into standardized after-visit summary documents. These after-visit summaries containing either GPT-generated or standard discharge instructions were randomly and blindly administered to Amazon MTurk respondents representing patient populations through Amazon MTurk Survey Distribution. Discharge instructions were assessed based on metrics of interpretability of significance, understandability, and satisfaction. RESULTS: Our findings revealed that survey respondents' perspectives regarding GPT-generated and standard discharge instructions were significantly (P=.01) more favorable toward GPT-generated return precautions, and all other sections were considered noninferior to standard discharge instructions. Of the 156 survey respondents, GPT-generated discharge instructions were assigned favorable ratings, "agree" and "strongly agree," more frequently along the metric of interpretability of significance in discharge instruction subsections regarding diagnosis, procedures, treatment, post-ED medications or any changes to medications, and return precautions. Survey respondents found GPT-generated instructions to be more understandable when rating procedures, treatment, post-ED medications or medication changes, post-ED follow-up, and return precautions. Satisfaction with GPT-generated discharge instruction subsections was the most favorable in procedures, treatment, post-ED medications or medication changes, and return precautions. Wilcoxon rank-sum test of Likert responses revealed significant differences (P=.01) in the interpretability of significant return precautions in GPT-generated discharge instructions compared to standard discharge instructions but not for other evaluation metrics and discharge instruction subsections. CONCLUSIONS: This study demonstrates the potential for LLMs such as ChatGPT to act as a method of augmenting current documentation workflows in the ED to reduce the documentation burden of physicians. The ability of LLMs to provide tailored instructions for patients by improving readability and making instructions more applicable to patients could improve upon the methods of communication that currently exist.

RESUMEN

BACKGROUND: Clinicians working with patients at risk of suicide often experience high stress, which can result in negative emotional responses (NERs). Such negative emotional responses may lead to less empathic communication (EC) and unintentional rejection of the patient, potentially damaging the therapeutic alliance and adversely impacting suicidal outcomes. Therefore, clinicians need training to effectively manage negative emotions toward suicidal patients to improve suicidal outcomes. METHODS: This study investigated the impact of virtual human interaction (VHI) training on clinicians' self-awareness of their negative emotional responses, assessed by the Therapist Response Questionnaire Suicide Form, clinicians' verbal empathic communication assessed by the Empathic Communication and Coding System, and clinical efficacy (CE). Clinical efficacy was assessed by the likelihood of subsequent appointments, perceived helpfulness, and overall interaction satisfaction as rated by individuals with lived experience of suicide attempts. Two conditions of virtual human interactions were used: one with instructions on verbal empathic communication and reminders to report negative emotional responses during the interaction (scaffolded); and the other with no such instructions or reminders (non-scaffolded). Both conditions provided pre-interaction instructions and post-interaction feedback aimed at improving clinicians' empathic communication and management of negative emotions. Sixty-two clinicians participated in three virtual human interaction sessions under one of the two conditions. Linear mixed models were utilized to evaluate the impact on clinicians' negative emotional responses, verbal empathic communication, and clinical efficacy; and to determine changes in these outcomes over time, as moderated by the training conditions. RESULTS: Clinician participants' negative emotional responses decreased after two training sessions with virtual human interactions in both conditions. Participants in the scaffolded condition exhibited enhanced empathic communication after one training session, while two sessions were required for participants in the non-scaffolded condition. Surprisingly, after two training sessions, clinical efficacy was improved in the non-scaffolded group, while no similar improvements were observed in the scaffolded group. CONCLUSION: Lower clinical efficacy after virtual human interaction training in clinicians with higher verbal empathic communication suggests that nonverbal expressions of empathy are critical when interacting with suicidal patients. Future work should explore virtual human interaction training in both nonverbal and verbal empathic communication.

RESUMEN

BACKGROUND: Little is known about how motor learning strategies (MLSs) can promote implicit and explicit motor learning processes. This study aimed to explore experts' perspectives on therapists' use of MLSs to promote specific learning processes in children with and without developmental coordination disorder (DCD). METHODS: In this mixed-methods study, two consecutive digital questionnaires were used to ascertain the opinions of international experts. Questionnaire 2 explored the findings of Questionnaire 1 in greater depth. In order to reach a certain level of agreement about the classification of MLSs as promoting either (more) implicit or (more) explicit motor learning, 5-point Likert scales were used in addition to open-ended questions. The open-ended questions were analysed with a conventional analysis approach. Open coding was performed by two reviewers independently. Categories and themes were discussed within the research team, taking both questionnaires as one dataset. RESULTS: Twenty-nine experts from nine different countries with different backgrounds in research, education and/or clinical care completed the questionnaires. The results of the Likert scales showed large variation. Two themes emerged from the qualitative analyses: (1) Experts found it difficult to classify MLSs as promoting either implicit or explicit motor learning, and (2) experts stressed the need for clinical decisionmaking when choosing MLSs. CONCLUSIONS: Insufficient insight was gained into how MLSs could promote (more) implicit or (more) explicit motor learning in children in general and in children with DCD specifically. But this study demonstrated the importance of clinical decisionmaking to model and adapt MLSs to child, task and environment, with therapists' knowledge of MLSs being an important prerequisite. Research is needed to better understand the various learning mechanisms of children and how MLSs can be used to manipulate these mechanisms.

RESUMEN

Sexual assault affects many people of all gender identities, yet most cases do not result in conviction. This may be due to common, inaccurate misperceptions juries hold about how sexual assault is perpetrated and how victims respond to sexual assault. Research has examined misperceptions relating to cisgender victims, yet little is known about the unique misconceptions and stereotypes that may unfairly disadvantage transgender victims or whether courts are attempting to safeguard against them. This article presents a literature review of empirical research on (mock) jurors' perceptions of transgender victims and a review of judicial instructions about gender identity. We find that empirical research is extremely limited with mixed findings, but many jurisdictions allow for judicial instructions warning jurors against prejudice based on gender identity. Further research is urgently needed to identify common misperceptions jurors may have that are specific to transgender victims to inform legal safeguards and improve justice outcomes.

RESUMEN

BACKGROUND: Utilizing the objective structured clinical examination (OSCE) ensures objectivity when it comes to the assessment of nursing students' skills and competency. However, one challenge in OSCE integration is rater and examinee training and orientation. AIM: This study employed a quasi-experimental design to evaluate the effectiveness of different instructional methodologies in training and preparing raters and examinees for the OSCE. METHODS: Participants were divided into three group of training methodologies: online, simulation, and traditional lecture (six raters and 18 examinees were assigned to each group). A total of 18 raters and 54 examinees partook. RESULTS: The study found that raters trained through simulation exhibited a slight agreement with their rates, compared to those who were trained online and in traditional lectures. Moreover, examinees who were trained through the simulation methodology performed better compared to those trained via the other methodologies. CONCLUSIONS: The study findings indicate that using simulation by training raters and examinees in the OSCE is the most effective approach.

RESUMEN

Selling products in kit form to consumers benefits both manufacturers and consumers - provided the instructions enable the customer to assemble the components correctly and safely. Poor usability of some self-assembly instructions is a continuing cause of consumer complaints- but the subject of only occasional ergonomics research interest. Relevant studies are widely dispersed across the literature - and across decades - but their findings generally agree on what makes some self-assembly illustrations more effective than others. This has just not been consolidated in any formally recognised guidance. This study has produced a comprehensive review of published work on the usability of self-assembly instructions (which need to convey most information pictorially) and makes detailed recommendations for best practice in their presentation. The evidence for the recommended best practices discussed in this paper will be reflected in the publication of an international standard that which is currently in the final drafting stages.


This review of published research into effective presentational techniques for self-assembly instructions was instigated to support a proposal for an international standard. That is now under development incorporating requirements based on the high degree of consensus the review found across a wide spread of types of study, locations and years.
