Standardized therapies after ECMO program (STEP); a novel approach to pediatric post-ECMO care.

BACKGROUND: The study objective was to characterize compliance with Standardized Therapy after ECMO Program (STEP), an intentional discharge pathway for extracorporeal membrane oxygenation (ECMO) survivors in a US pediatric hospital. METHODS: The program identified pediatric ECMO survivors before discharge, appropriate consultations were reviewed and requested, families were educated on ECMO sequelae, and ECMO summaries were sent to pediatricians. Compliance with institutional post-ECMO guidelines was evaluated before and after STEP implementation. RESULTS: We identified 77 ECMO survivors to hospital discharge (36 [46.8%] before and 41 [53.2%] after STEP implementation). There was a significant increase in complete (38.8% vs. 74.2%, p < 0.001) and time-appropriate neurodevelopmental testing (71.4% vs. 95.6%, p = 0.03). Significant increase in inpatient evaluations by neurology (52.7% vs. 75.6%, p = 0.03) and audiology (66.7% vs. 87.8%, p = 0.02), and in referrals for outpatient audiology (66.6 vs. 95.1%, p = 0.002), physical therapy (P.T.) (63.8% vs. 95.1%, p = 0.001), occupational therapy (O.T.) (63.8% vs. 95.1%, p = 0.001) and speech-language pathology (S.L.P.) (55.5% vs. 95.1%, p < 0.001) were noted. CONCLUSION: Implementing an intentional discharge pathway for pediatric ECMO survivors (STEP) successfully increases inpatient and outpatient compliance with hospital and Extracorporeal life support organization (ELSO) follow-up guidelines. It leads to timely and complete neurodevelopmental evaluation.

Posttraumatic stress disorder (PTSD) prevalence: an umbrella review.

Posttraumatic stress disorder (PTSD) is one of the most serious and incapacitating mental diseases that can result from trauma exposure. The exact prevalence of this disorder is not known as the literature provides very different results, ranging from 2.5% to 74%. The aim of this umbrella review is to provide an estimation of PTSD prevalence and to clarify whether the prevalence depends on the assessment methods applied (structured interview v. self-report questionnaire) and on the nature of the traumatic event (interpersonal v. not-interpersonal). A systematic search of major databases and additional sources (Google Scholar, EBSCO, Web of Science, PubMed, Galileo Discovery) was conducted. Fifty-nine reviews met the criteria of this umbrella review. Overall PTSD prevalence was 23.95% (95% confidence interval 95% CI 20.74-27.15), with no publication bias or significant small-study effects, but a high level of heterogeneity between meta-analyses. Sensitivities analyses revealed that these results do not change after removing meta-analysis also including data from underage participants (23.03%, 95% CI 18.58-27.48), nor after excluding meta-analysis of low quality (24.26%, 95% CI 20.46-28.06). Regarding the impact of diagnostic instruments on PTSD prevalence, the results revealed a lack of significant differences in PTSD prevalence when structured v. self-report instruments were applied (p = 0.0835). Finally, PTSD prevalence did not differ following event of intentional (25.42%, 95% CI 19.76-31.09) or not intentional (22.48%, 95% CI 17.22-27.73) nature (p = 0.4598). The present umbrella review establishes a robust foundation for future research and provides valuable insights on PTSD prevalence.

EXPRESS: Enhanced intentional inhibition with increased subliminal action preparation.

Intentional inhibition, the ability to voluntarily inhibit or suspend an action preparation, is closely related to self-control. It is widely believed that subliminal stimuli can also activate action preparation, but whether intentional inhibition is enhanced or disrupted with greater subliminal action preparation remains unclear. In this study, participants voluntarily decided whether or not to perform the action in the scenario with subliminal action preparation, and the strength of the action preparation was manipulated by a precueing procedure. The results, based on behavioral measures and drift-diffusion models, showed that intentional inhibition enhanced with increasing subliminal action preparation, suggesting that as subliminal action preparation increases, people are more inclined to make inhibitory decisions. This study provides evidence for a framework in which strong subliminal action preparation induces enhanced cognitive monitoring.

The effect of electrical muscle stimulation on intentional binding and explicit sense of agency.

The motivating question for this study is determining whether electrical muscle stimulation (EMS)-induced movements can extend the user's ability without reducing the sense of agency. Moreover, it is crucial to find the timing of the EMS application that is robust against individual differences and environmental changes. Previous studies have reported that the user-specific EMS-application timings, determined through explicit measures of sense of agency, would effectively shorten their reaction time in a push task while maintaining their sense of agency. However, no study has investigated EMS-application timings in relation to implicit measures of sense of agency. Intentional binding, an example of an implicit measure, refers to the phenomenon whereby the interval between an intentional action and the subsequent perceptual outcome is typically perceived to be shorter than the actual interval. By measuring this perceptual shift using a Libet clock, we have identified an EMS-application timing that accelerates the users' push action while maintaining their sense of agency. First, to conduct the EMS-application experiment while appropriately maintaining the intentional binding effect, we designed a new push task such that a pre-action, as the base timing of the EMS-application trigger, always occurs just before the push movement. (1) We showed the difference between the action-binding effect of EMS-induced involuntary movements and voluntary push movements. Subsequently, (2) we identified the EMS application timing that significantly shifted judgments of action tasks while accelerating voluntary movements. Additionally, (3) we demonstrated that the EMS application could accelerate user pushing movement while maintaining the sense of agency at this specific application time. The proposed EMS in the novel pushing setup was found to be robustly effective against individual and environmental changes.

Suicide-Related Emergency Department Visits Before and During the COVID-19 Pandemic in the United States.

Background and aim  The impact of COVID-19 on suicide rates is a significant concern, given the widely recognized psychological effects that the pandemic has had on mental health. Overall, suicide trends remained relatively stable. Yet, specific age groups, races, and genders experienced an increase in suicide rates. A better understanding of suicide trends over time is critical to identifying and addressing mental health crises exacerbated by the pandemic. This study aimed to study whether the years preceding and during the pandemic were associated with an increase in emergency department (ED) visits in the United States for suicide or intentional injury.  Methodology Secondary analyses of data from the National Hospital and Ambulatory Medical Care Survey (2018-2021) were conducted. The frequency of ED visits due to intentional injury or suicide was compared in 2018-2019 (pre-COVID-19 pandemic onset) to those of 2020-2021 (during-COVID-19 onset). Logistic regression was used to estimate odd ratios (ORs) and corresponding 95% confidence intervals. Patient's race, sex, age, and regional differences were assessed as covariates. Results There were 27,516 and 22,247 visits assessed in the pre- and during-COVID-19 periods, respectively. In total, 1,375 visits were due to intentional injury/suicide. No differences were found comparing the proportion of visits due to intentional injuries/suicide pre- and during-COVID-19 periods (2.6% in both) The adjusted OR (aOR) comparing pre- versus during-COVID-19 for emergency room visits due to intentional injury/suicide was not significantly different from 1 (aOR = 0.98, 95% CI 0.84-1.15). The odds of suicide/intentional injury were 53% higher in males (aOR = 1.53, 95%CI 1.30-1.81), in those with ages 18-44 years (aOR = 7.24, 95% CI 4.92-10.67) and 45-64 years (aOR = 3.55, 95% CI 2.31-5.47) compared to those 65 years or older, and in non-Hispanic Black individuals compared to non-Hispanic White individuals (aOR = 1.29, 95% CI 1.05-1.58).  Conclusions Using a national sample of ED visits, we found no association between the pre- and COVID-19 pandemic periods and the proportion of visits due to intentional injury/suicide. However, the study's proportional prevalence design limits its ability to estimate actual risk, requiring a cautious interpretation of the findings. Despite these limitations, the observed increased odds of suicide or intentional injury in specific subgroups underscore the need for targeted interventions. Further research is crucial to assess the long-term impacts of COVID-19.

Permanently infertile couples and family building-a cross-sectional survey in Denmark.

STUDY QUESTION: Which decision-making factors influence family building among permanently infertile couples? SUMMARY ANSWER: Ethical, legal, and financial considerations outweigh genetic relatedness in decision-making, favouring domestic gestational surrogacy, if this were possible, over international options. WHAT IS KNOWN ALREADY: Permanent infertility affects 4-5% of people in the fertile age. Their family-building options include adoption, surrogacy, uterus transplantation, foster care, and intentional multiple parenthood. However, in most countries, including Denmark, legal barriers constrain these methods due to surrogacy restrictions, suspended international adoptions, and the experimental status of uterus transplantation. Despite existing research on surrogacy, adoption, and specific causes of permanent infertility, a significant gap remains in our understanding of how couples with permanent infertility make family-building decisions within these limited frameworks. STUDY DESIGN, SIZE, DURATION: This cross-sectional study with 150 permanently infertile Danish participants was conducted from June to November 2023 using an online questionnaire. Multiple strategies, such as online forums, fertility clinics, hospital departments, and snowballing, were used to recruit a diverse sample. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included couples aged 26-50 years facing permanent infertility due to the following primary causes: women without a uterus (15%), women with a non-functional uterus (47%) or women for whom pregnancy would be life-threatening (9%), male couples (16%), transgender partner couples (2%), and other causes (11%). The survey collected data on demographics, reproductive history, family-building choices, and communication strategies. Closed questions were analysed using descriptive statistics. MAIN RESULTS AND THE ROLE OF CHANCE: Among 150 respondents, 41% had used transnational surrogacy, 27% adoption, 14% chose to remain childless, and 19% were undecided. Critical factors on family-building decisions were ethical, legal, and financial concerns which ranked higher than genetic relatedness. Despite the complexity of family building, most participants were open about their child's origin and received social support. If all family-building methods were legal and available in Denmark, domestic gestational surrogacy would be the preferred method, with uterus transplantation and remaining childless being least popular. LIMITATIONS, REASONS FOR CAUTION: The sample size is relatively small, despite the use of a variety of recruitment strategies. Nevertheless, this has ensured a diverse cohort representing the different reasons for infertility and family-building choices. It is important to note that the strategies may have favoured individuals achieving parenthood. WIDER IMPLICATIONS OF THE FINDINGS: The finding of our study reveals a notable gap between available family-building options in Denmark and the preferences of couples facing permanent infertility. These insights could be instrumental for organizations reviewing and developing family-building frameworks. Furthermore, for healthcare professionals guiding couples experiencing infertility issues in their attempts to build a family, an understanding of these preferences is essential to facilitate informed decisions about their future family plans.

Use of Subfascial Passive Bile Bag Drainage for the Management of Durotomies in Spine Surgery.

INTRODUCTION: Historically, the use of subfascial drains for the management of durotomies was avoided due to concerns about the creation of cerebrospinal fluid (CSF) fistulas. Currently, there are limited series utilizing subfascial drainage for CSF leak management, many of which utilize suction drainage. We report our experience with the use of subfascial passive drainage in the management of such leaks. OBJECTIVE: To demonstrate the efficacy of a passive subfascial bile bag for diversion of CSF post-operatively in concert with a post-operative head of bed (HOB) protocol for the management of durotomies in spine surgery. METHODS: We performed a retrospective chart review of patients who underwent spinal surgery at a single institution performed by one surgeon. Cases utilizing a passive subfascial bile bag for durotomies were identified. A total of 1,882 consecutive surgeries were reviewed, and 108 met the inclusion criteria. The primary outcome was return to the operating room (OR) and/or the need for lumbar drain placement. Patient sociodemographic information and pre-, intra-, and post-operative clinical characteristics were reviewed. RESULTS: A total of 108 patients underwent subfascial bile bag CSF diversion after intra-operative durotomy. Four patients (3.7%) experienced post-operative CSF leakage requiring lumbar drain placement, while only two (1.9%) patients required a return to the OR. One patient returned to the OR for symptomatic pseudomeningocele and the other for ongoing CSF drainage from their wound. CONCLUSION:  Durotomies are known to increase complication rates, including reoperation. The use of subfascial passive bile bag drainage in concert with a post-operative HOB protocol is a safe and effective manner to manage durotomies while minimizing the need for reoperation.

Laxative Properties of Microencapsulated Oleic Acid Delivered to the Distal Small Intestine in Patients with Constipation after Bariatric Surgery or Treatment with Glucagon-Like- Peptide 1 Analogues.

BACKGROUND: Constipation is prevalent after bariatric surgery and glucagon-like-peptide 1 (GLP-1) analogues. Increasing fat content in the distal small intestine and colon can enhance colonic peristalsis, potentially alleviating symptoms of constipation. AIM: We investigated whether oleic acid can ameliorate constipation in patients undergoing bariatric surgery or receiving GLP-1 analogues. METHODOLOGY: Fourteen adults with chronic constipation according to Rome IV criteria following bariatric surgery or GLP-1 analogues were on stable treatment for constipation for more than 4 weeks. This randomized double-blind crossover trial compared microcapsules containing 21.25 g of oleic acid delivered in the distal small intestine or the stomach. The primary outcome was changed in the number of bowel motions over 24 h. Exploratory endpoints included alterations in straining, diarrhoea, faecal leakage over 24 h and hunger, fullness, nausea and calorie intake for the 3 h after ingesting the microcapsules. FINDINGS: Receiving oleic acid into the distal small intestine increased number of bowel movements per day (2.5 vs 1.1, p = 0.009) and caused softer stool consistency (p = 0.03). 9/14 of the control group passed motions and 13/14 of the intervention group passed motions in 24 h (p = 0.059). No significant differences were observed in straining (p = 0.65), rapid bowel movements (p = 0.08), accidental leakage (p = 0.32), hunger, fullness, nausea or food intake between the groups (all p > 0.05). There were no disparities in safety profile between groups. CONCLUSION: Microcapsules containing oleic acid delivered to the distal small intestine appear to be a safe and effective relief from chronic constipation in patients undergoing bariatric surgery and/or receiving GLP-1 analogues.

An Experiential Approach to Training Medical Faculty to Coach: "The Total Experience was Much More Than the Sum of Its Parts".

Coaching in academic medicine may be used for performance improvement as well as personal and professional growth and development. Medical faculty used to advising and mentoring learners may find it challenging to transition to coaching. Limited information is available about educating physicians to take on the role of coaching. We investigated a faculty coach training program at an academic medical center, using qualitative methods to explore how participants' perceptions of the training aligned with the elements of Self-Determination Theory (SDT) and Intentional Change Theory (ICT) that were taught using the principles of Experiential Learning Theory (ELT). Based on findings that illuminated understanding and practice of coaching, it may be summarized that the application of experiential learning may be an effective approach in helping faculty embrace the principles of SDT and ICT and make the shift to transformational coaching.

EFSA statement on the requirements for whole genome sequence analysis of microorganisms intentionally used in the food chain.

Microorganisms, genetically modified or not, may be used in the food chain either as active agents, biomasses or as production organisms of substances of interest. The placement of such microorganisms or their derived substances/products in the European market may be subject to a premarket authorisation process. The authorisation process requires a risk assessment in order to establish the safety and/or the efficacy of the microorganism(s) when used in the food chain as such, as biomasses or as production strains. This includes a full molecular characterisation of the microorganism(s) under assessment. For certain regulated products, the use of whole genome sequence (WGS) data of the microorganism is established as a requirement for the risk assessment. In this regard, data obtained from WGS analysis can provide information on the unambiguous taxonomic identification of the strains, on the presence of genes of concern (e.g. those encoding virulence factors, resistance to antimicrobials of clinical relevance for humans and animals, production of harmful metabolites or of clinically relevant antimicrobials) and on the characterisation of genetic modification(s) (where relevant). This document provides recommendations to applicants on how to describe and report the results of WGS analyses in the context of an application for market authorisation of a regulated product. Indications are given on how to perform genome sequencing and the quality criteria/thresholds that should be reached, as well as the data and relevant information that need to be reported, if required. This updated document replaces the EFSA 2021 Statement and reflects the current knowledge in technologies and methodologies to be used to generate and analyse WGS data for the risk assessment of microorganisms.

Association of ambient temperature with intentional self-harm and suicide death in Seoul: a case-crossover design with a distributed lag nonlinear model.

Previous epidemiological studies have reported a short-term association between ambient temperature and suicide risk. To gain a clearer understanding of this association, it is essential to differentiate the risk factors for intentional self-harm (ISH) from those specifically associated with suicide deaths. Therefore, this study aims to examine whether the association between daily temperature and ISH or suicide deaths differs by age and sex. Between 2014 and 2019, cases of emergency room visits related to ISH and suicide deaths in Seoul were identified. A time-stratified case-crossover design was used to adjust for temporal trends and seasonal variation. A distributed lag nonlinear model was used to analyze the nonlinear and time-delayed effect of ambient temperature on ISH and suicide deaths. Positive associations were observed between temperature and both ISH and suicide deaths. For ISH, the relative risk (RR) was high at 1.17 (95% confidence interval (CI): 1.03, 1.34) for a temperature of 25.7 °C compared with 14.8 °C. The RR for suicide death was higher than those for ISH, at 1.43 (95% CI: 1.03, 2.00) for a temperature of 33.7 °C. These associations varied by age and sex, with males and females aged 35-64 years showing increased susceptibility to suicide deaths. This study provides detailed evidence that unusually high temperatures, both anomalous and out of season, may trigger suicidal behaviors, including both ISH and suicide deaths.

Correlates of Theta and Gamma Activity during Visuospatial Incidental/Intentional Encoding and Retrieval Indicate Differences in Processing in Young and Elderly Healthy Participants.

Incidental visuospatial learning acquired under incidental conditions is more vulnerable to aging than in the intentional case. The theta and gamma correlates of the coding and retrieval of episodic memory change during aging. Based on the vulnerability of incidental coding to aging, different theta and gamma correlates could occur under the incidental versus intentional coding and retrieval of visuospatial information. Theta and gamma EEG was recorded from the frontotemporal regions, and incidental/intentional visuospatial learning was evaluated in young (25-60 years old) and elderly (60-85 years old) participants. The EEG recorded during encoding and retrieval was compared between incidental low-demand, incidental high-demand, and intentional conditions through an ANCOVA considering the patient's gender, IQ, and years of schooling as covariates. Older adults exhibited worse performances, especially in place-object associations. After the intentional study, older participants showed a further increase in false-positive errors. Higher power at the theta and gamma bands was observed for frontotemporal derivations in older participants for both encoding and retrieval. Under retrieval, only young participants had lower power in terms of errors compared with correct responses. In conclusion, the different patterns of power and coherence support incidental and intentional visuospatial encoding and retrieval in young and elderly individuals. The correlates of power with behavior are sensitive to age and performance.

Instantaneous phase of rhythmic behaviour under volitional control.

The phase of signals representing cyclic behavioural patterns provides valuable information for understanding the mechanisms driving the observed behaviours. Methods usually adopted to estimate the phase, which are based on projecting the signal onto the complex plane, have strict requirements on its frequency content, which limits their application. To overcome these limitations, input signals can be processed using band-pass filters or decomposition techniques. In this paper, we briefly review these approaches and propose a new one. Our approach is based on the principles of Empirical Mode Decomposition (EMD), but unlike EMD, it does not aim to decompose the input signal. This avoids the many problems that can occur when extracting a signal's components one by one. The proposed approach estimates the phase of experimental signals that have one main oscillatory component modulated by slower activity and perturbed by weak, sparse, or random activity at faster time scales. We illustrate how our approach works by estimating the phase dynamics of synthetic signals and real-world signals representing knee angles during flexion/extension activity, heel height during gait, and the activity of different organs involved in speech production.

Effect of Dental Implant System-Assisted Tooth Intentional Replantation in the Treatment of Anterior Teeth with Pathological Tooth Flaring, Drifting and Elongation in Patients with Stage III/IV Periodontitis: a Case Series.

OBJECTIVE: To investigate the clinical effect of implant-assisted dental intentional replantation (IR) for the treatment of "drifted" anterior periodontally hopeless teeth (PHT). METHODS: The present authors recruited 22 patients with stage III/IV periodontitis who suffered drifting of the maxillary anterior teeth, with a total of 25 teeth. The PHT were extracted for in vitro root canal treatment (RCT). The root surface was smoothed and the shape was trimmed, and the alveolar socket was scratched. The dental implant system was used to prepare the alveolar socket according to the direction, depth and shape of the tooth implantation. The PHT were reimplanted into the prepared alveolar socket. The periodontal indicators were analysed statistically before and after surgery. RESULT: Twenty-two patients who completed the full course of treatment, with a total of 25 PHT, had a successful retention rate of 88%. Mean periodontal probing depth (PPD) decreased by 2.880 ± 0.556 mm and 3.390 ± 0.634 mm at 6 months and 1 year, respectively, and clinical attachment loss (CAL) decreased by 2.600 ± 0.622 mm and 2.959 ± 0.731 mm at the same time points, respectively, showing significant improvement (P < 0.05). CONCLUSION: Dental implant system-assisted IR can effectively preserve "drifted" natural PHT in patients with stage III/IV periodontitis.

Explicit and implicit sense of agency in depersonalisation experiences.

The sense of agency, the feeling of controlling one's bodily actions and the world is altered in Depersonalisation (DP), a condition that makes people feel detached from one's self and body. To investigate the link between depersonalisation and both implicit and explicit sense of agency, an online study was conducted using the influential Intentional Binding paradigm in a sample of non-clinical DP participants. The results did not reveal significant differences between individuals with low and high occurrences of DP experiences on the implicit and explicit sense of agency. However, participants with high occurrences of DP experiences showed a more time-sensitive explicit sense of agency and greater temporal distortions for short intervals in the absence of self-initiated motion. These results suggest that there is a discrepancy between implicit and explicit sense of agency in people with high levels of depersonalisation. Altogether, these findings call for further investigations of the key role of time perception on altered sense of self and agency in both non-clinical and clinical populations, to disentangle the mechanisms associated with the explicit and implicit sense of agency.

Sex differences among patients with intentional poisoning presenting to the emergency Department at a Tertiary Care Centre in Beirut, Lebanon.

Poisoning poses a worldwide public health challenge and recent data from Lebanon in 2020 revealed that over half patients presenting with acute toxicological exposure intentionally poisoned themselves, primarily with suspected suicidal intent. This study aims to assess sex disparities in intentional toxicological exposures among patients presenting to the Emergency Department, at a tertiary care centre in Lebanon. This was a secondary analysis of an existing toxicological database, including patients aged 6 years and older admitted due to acute overdose from March 2015 to August 2022. A total of 444 cases of intentional poisoning were analysed, with 302 (68.0%) women. The primary cause of intentional poisoning was suspected suicide in both sexes, significantly more common in women (85.1% versus 65.5%, P < 0.001). Specific agents exposed to patients varied by sex; sedatives/hypnotics/antipsychotics, antihistamines, and melitracen/flupentixol were significantly more prevalent in women (P < 0.001) while men showed higher prevalence for ethanol (P = 0.02), stimulants, street drugs and opioids (P < 0.001). Our study underscores substantial sex differences in intentional poisoning cases in Lebanon. Women exhibited a higher likelihood of exposures to sedatives/hypnotics/antipsychotics, antihistamines and melitracen/flupentixol, while stimulant drugs, ethanol, and opioids were prevalent in men. Developing proper and effective sex-specific measures may mitigate potential physical and psychological consequences.

Dynamic of Fire Deaths: Two Emblematic Cases of Intentional Burning.

Background: Homicide by burning is rare, involving victims exposed to direct flames, often with accelerants. This demonstrates excessive force by the assaulter. A thorough investigation is vital as fire can conceal pathological findings. This study presents two emblematic cases of intentional burning. Case report: Two cases of homicide by fire are detailed. The first involves a male found dead in a fire-damaged apartment, doused with flammable liquid and set on fire by his partner. The autopsy showed heat hematoma and soot in the trachea and large bronchi. The second case involves a female set on fire with gasoline by an acquaintance, sustaining burns over 90% of her body and dying from hypovolemic shock. The autopsy revealed effusions in pleural and peritoneal cavities and a hyperaemic trachea. Conclusions: Intentional burnings are sporadic and difficult to classify without testimonial evidence. The difference between homicide and accidental burns relies on circumstantial evidence and antemortem injuries. Vital reactions to thermal lesions include red-base blisters, dilated capillaries, leukocyte infiltration, coagulative necrosis, heat hematoma, and soot in the airways. High carboxyhemoglobin levels indicate vitality. The first case showed heat hematoma and tracheal soot, while the second exhibited severe burns leading to hypovolemic shock. Testimonial evidence and crime scene examination were crucial in determining the homicidal nature. Forensic investigation of charred corpses requires a comprehensive evaluation of all available data. Crime scene analysis, combined with autopsy, toxicological tests, and post-mortem CT scans, helps establish the cause of death and differentiate between ante- and postmortem injuries.

Common intentional binding effects across diverse sensory modalities in touch-free voluntary actions.

The intentional binding effect refers to the phenomenon where the perceived temporal interval between a voluntary action and its sensory consequence is subjectively compressed. Prior research revealed the importance of tactile feedback from the keyboard on this effect. Here we examined the necessity of such tactile feedback by utilizing a touch-free key-press device without haptic feedback, and explored how initial/outcome sensory modalities (visual/auditory/tactile) and their consistency influence the intentional binding effect. Participants estimated three delay lengths (250, 550, or 850 ms) between the initial and outcome stimuli. Results showed that regardless of the combinations of sensory modalities between the initial and the outcome stimuli (i.e., modal consistency), the intentional binding effect was only observed in the 250 ms delay condition. This findings indicate a stable intentional binding effect both within and across sensory modalities, supporting the existence of a shared mechanism underlying the binding effect in touch-free voluntary actions.

Facilitating and hindering factors for routine adaptations in manufacturing and effects on human performance- unexpected insights from three experimental studies in a special purpose setting.

Consumer behaviour changes and strategic management decisions are driving adaptations in manufacturing routines. Based on the theory of situational strength, we investigated how contextual and person-related factors influence workers' adaptation in a two-worker position routine. Contextual factors, like retrieval cues (Study 1), time pressure (Study 2), and convenience (Study 3), were varied. Person-related factors included retentivity, general and routine-specific self-efficacy, and perceived adaptation costs. Dependent variables included various error types and production time before and after adaptation. In each study, 148 participants were trained in a production routine at t1 and executed an adapted routine at t2, one week later. Repeated measures ANOVA for performance at t1 and t2, and MANOVA for performance at t2, revealed that time increased for all groups at t2. For participants in Studies 1 & 2, error rates remained consistent. Retentivity significantly impacted errors at both t1 and t2, emphasising that routine changes in a 'running business' take time, regardless of contextual factors. Workers with lower retentivity may require additional support.

When production routines are changed while daily business operations continue, and on-the-job training is the sole method, a slowdown in production speed should be anticipated. Workers, particularly those with low retentivity, require additional support and training to minimise errors when executing the adapted routine.

Sense of agency in schizophrenia: A reconciliation of conflicting findings through a theory-driven literature review.

The sense of agency is the experience of being the author of self-generated actions and their outcomes. Both clinical manifestations and experimental evidence suggest that the agency experience and the mechanisms underlying agency attribution may be dysfunctional in schizophrenia. Yet, studies investigating the sense of agency in these patients show seemingly conflicting results: some indicated under-attribution of self-agency (coherently with certain positive symptoms), while others suggested over-attribution of self-agency. In this review, we assess whether recent theoretical frameworks can reconcile these divergent results. We examine whether the identification of agency abnormalities in schizophrenia might depend on the measure of self-agency considered (depending on the specific task requirements) and the available agency-related cues. We conclude that all these aspects are relevant to predict and characterize the type of agency misattribution that schizophrenia patients might show. We argue that one particular model, based on the predictive coding theory, can reconcile the interpretation of the multifarious phenomenology of agency manifestations in schizophrenia, paving the way for testing agency disorders in novel ways.
