Artificial mechano-nociceptive system based on transparent ITO/AlN/ITO memristor nociceptor neuron

Artificial nociceptors demonstrate significant potential in emerging fields such as intelligent prosthetics, humanoid robotics, and electronic skin, capable of transducing external noxious stimuli to the central nervous system. Unlike common sensory neurons, nociceptors exhibit unique characteristics, including “no adaptation,” “relaxation,” “threshold firing,” and “sensitization of allodynia/hyperalgesia.” This study presents a forming-free volatile transparent ITO/AlN/ITO memristor that emulates biological nociceptor behaviors. Leveraging this artificial nociceptor, an artificial mechano-nociceptive system is developed by integrating the ITO/AlN/ITO memristor into a piezoelectric force sensor system for pain sensing and noxious stimuli warning. This research contributes to the advancement of human cognitive capability emulation and artificial intelligence systems, particularly in the domain of pain perception and response.

Association Between Internet Addiction, Perceived Stress, Salivary Cortisol Level and Educational Declare in Dental Students

Background and Objectives: Internet addiction is one of the challenges of students that may affect their academic performance and cause stress. One of the metabolic changes related to stress is the salivary cortisol level. This study aims to evaluate the relationship of internet addiction with perceived stress, salivary cortisol level, and academic failure in dental students. Methods: In this descriptive-analytical study with a cross-sectional design, 123 dental students from Qom University of Medical Sciences participated. They were selected by a census sampling method. A demographic form, the internet addiction test, and the perceived stress scale were completed by them. Their academic failure was assessed and their salivary cortisol level was measured by the ELISA method. Data were analyzed using ANOVA, t-test, Pearson correlation test, and regression analysis. Results: Internet addiction had a positive and significant relationship with perceived stress (r=0.21, P=0.003) and its two domains of negative perception (r=0.301, P=0.005) and positive perception (r=0.279, P=0.009). However, it had no significant relationship with salivary cortisol level (P=0.123) or academic failure (P=0.614). Conclusion: It seems that decreasing internet addiction can reduce the perceived stress of dental students.

Comparison of surgical performance using articulated (ArtiSential®) and conventional instruments for colorectal laparoscopic surgery: A single-centre, open, before-and-after, prospective study.

Rigid surgical instruments limit movement whereas articulated instruments offer better control in small spaces and allow for intuitive and ergonomic movements. However, the effectiveness of the use of articulated instruments in improving colorectal laparoscopic outcomes remains unclear. The aim of this work was to determine whether colorectal laparoscopic surgical proficiency improved when multijoint instruments were used instead of conventional ones. We enrolled 70 consecutive patients (n = 20 for conventional instruments) aged 19-80 years who underwent elective laparoscopic surgery for colorectal diseases. Unedited surgery videos were validated using the modified Global Operative Assessment of Laparoscopic Skills (mGOALS) scale. Learning curves were analysed using a cumulative sum control chart for mGOALS grades. The surgery type, length of hospital stay and 30-day postoperative complication rates were comparable between the groups, and the surgeon's mGOALS grades were similar (p = 0.190). However, in the articulated group, the scores were significantly higher for depth perception (p = 0.012) and tissue-handling domains (p = 0.046), while surgical duration was significantly shorter and intraoperative blood loss was significantly lower (p = 0.022), compared with those in the conventional (p = 0.002) group. Learning curve findings indicated that the first 10 and subsequent 40 surgeries in the articulated group were within the inexperienced and experienced phases, respectively. The mGOALS score in the experienced phase improved in the articulated group compared with that in the conventional group (p = 0.036). The use of articulated instruments in laparoscopic colorectal surgery showed potential benefits. Further studies are needed to confirm these findings.

Nearsighted empathy: exploring the effect of empathy on distance perception, with eye movements as modulators

Empathy, a cornerstone of social interaction, involves shared representation, eliciting vicarious emotions. However, its influence on shared perceptual representations, particularly in foundational domains such as distance perception, remains unexplored. In this study, we introduce a novel adaptation of the empathy for pain task to investigate empathy’s influence on distance perception. We also examine how two personality traits, trait empathy and alexithymia, modulate this relationship. Utilizing eye-tracking technology, we examine how attention allocation to different facial and bodily features affects empathy’s impact on distance perception. Our findings indicate that empathy biases individuals to perceive targets as closer, with trait empathy reinforcing this effect and alexithymia attenuating it. Furthermore, we demonstrate that heightened attention to eyes and face correlates with perceiving targets as closer, while attention to hand shows the opposite trend. These results underscore the broader influence of empathy beyond shared emotions, revealing its capacity to alter perceptual processes. By elucidating the interplay between personality traits and visual inputs in shaping these alterations, our study offers valuable insights for future research exploring the role of shared representation in empathy across various perceptual domains.

Using word clouds to reveal patients' perceptions about their arthritis.

Patients' perceptions about their illness have the power to influence health outcomes. However, existing illness belief measures can be burdensome. Using word clouds to illustrate patients' experiences is potentially a novel solution, but research is lacking in this area. This study aimed to explore whether word clouds illustrate patients' perceptions about their illness and to determine commonalities and differences in experiences of rheumatic diseases. A cross-sectional study was conducted with 323 patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or gout in New Zealand. Participants reported two words describing their inflammatory arthritis experience and completed the Brief Illness Perception Questionnaire. Word clouds were generated from participants' responses, and analysis of variance models were used to explore perceptions between groups. Eleven themes were identified, with each constituting a percentage of total word occurrence and weighting in word clouds. Symptom/sensation was the most prominent theme across all conditions (35%-61%), followed by affect/emotional experience (16%-25%). Theme prevalence varied across word clouds for each condition. Social impact was more prevalent for gout, and burden/intrusion was more prominent for ankylosing spondylitis. Functioning was less prevalent in the gout word cloud than in other conditions. There was moderate overlap between word cloud themes and illness perception domains. Word clouds uniquely identified themes related to burden/intrusion, functioning, opportunity, and social impact of illness. This study supports using word clouds as a low-burden method of examining the experiences of patients with inflammatory arthritis and could be tested with other patient groups.

Inflammation biomarkers and neurobehavioral performance in rural adolescents.

Systemic inflammation has been associated with lower neurobehavioral performance in diverse populations, yet the evidence in adolescents remains lacking. Cytokines can alter neural network activity to induce neurocognitive changes. This work seeks to investigate the association between inflammation and neurobehavior in adolescents living in a rural region of Ecuador. We examined 535 adolescents in rural communities of Ecuador (ESPINA study), 508 of which had neurobehavioral assessments (NEPSY-II) and circulating plasma levels of inflammatory markers (CRP, IL-6, TNF-⍺, sICAM-1, sVCAM-1, SAA, and sCD14). Associations between inflammatory biomarker concentrations and neurobehavioral scores were examined using adjusted bivariate semi-parametric models with generalized estimating equations. A partial least square regression approach was used to create composite variables from multiple inflammation biomarkers and model their association with cognitive outcomes. Higher sCD14 and TNF-α concentrations were significantly associated with lower social perception scores, by -0.47 units (95% CI: -0.80, -0.13) and -0.42 (-0.72, -0.12) for every 50% increase in inflammatory marker concentration, respectively. Similarly, every 50% increase in the inflammation summary score was associated with a significantly lower Social Perception score by -0.11 units (-0.19, -0.03). A unit increase in inflammatory composites of seven markers were associated with lower scores in language (-0.11 units, p=0.04), visuospatial processing (-0.15, p= 0.09), and social perception (-0.22, p=0.005) domains. Higher levels of inflammation were associated with lower neurobehavioral performance in adolescents, especially with social perception. In addition, using a robust analytic method to examine an association between a composite inflammatory variable integrating seven markers led to additional findings, including the domains of language and visuospatial processing. A longitudinal follow-up of such investigations could unveil potential changes in inflammation-neurobehavior performance links through developmental stages and intervention opportunities.

Foundation models in robotics: Applications, challenges, and the future

We survey applications of pretrained foundation models in robotics. Traditional deep learning models in robotics are trained on small datasets tailored for specific tasks, which limits their adaptability across diverse applications. In contrast, foundation models pretrained on internet-scale data appear to have superior generalization capabilities, and in some instances display an emergent ability to find zero-shot solutions to problems that are not present in the training data. Foundation models may hold the potential to enhance various components of the robot autonomy stack, from perception to decision-making and control. For example, large language models can generate code or provide common sense reasoning, while vision-language models enable open-vocabulary visual recognition. However, significant open research challenges remain, particularly around the scarcity of robot-relevant training data, safety guarantees and uncertainty quantification, and real-time execution. In this survey, we study recent papers that have used or built foundation models to solve robotics problems. We explore how foundation models contribute to improving robot capabilities in the domains of perception, decision-making, and control. We discuss the challenges hindering the adoption of foundation models in robot autonomy and provide opportunities and potential pathways for future advancements.

Efficacy of Danlou tablets in patients with acute coronary syndrome undergoing percutaneous coronary intervention: a multicenter prospective cohort study.

Danlou tablets (DLTs) have been widely used to treat coronary heart disease in China. However, the benefits associated with DLT for patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) in routine practice require further investigation. To investigate the effectiveness of DLT in patients with ACS undergoing PCI. This multicenter prospective cohort study for patients with ACS undergoing PCI was conducted in 40 centers in mainland China from February 2012 to December 2018. This trial is registered under ChiCTR-OOC-14005552. Patients were assigned to either the DLT group or the conventional medicine (CM) group based on whether they used DLT prior to enrollment. The duration of DLT use (1.5 g, three times a day) was 12 months. The primary endpoint comprised of cardiac death, non-fatal myocardial infarction, and urgent revascularization. Secondary endpoint included rehospitalization owing to ACS, heart failure, stroke, and other thrombotic events. The Seattle Angina Questionnaire (SAQ) was used to assess quality of life (QOL). Primary and secondary endpoints were followed up for 36 months, and the SAQ was followed up for 12 months. The Cox proportional hazards regression model was used to analyze the independent effect of DLT on primary and secondary endpoints. Propensity score matching (PSM) analyses were performed to mitigate bias. Survival estimation was performed using Kaplan-Meier survival curves and log-rank tests in the PSM cohort, and landmark analyses were used for further evaluation of primary and secondary endpoints. Subgroup analyses and interactions confirmed the robustness of the findings. Linear mixed effects models were used to assess the QOL. Overall, 936 patients were enrolled in this cohort study, of whom 875 completed follow-up. The primary and secondary endpoints had no significantly difference between the DLT and CM groups after Cox proportional hazards models. Kaplan-Meier survival curves and log-rank tests performed in the PSM cohort also found no significant differences between the two groups on primary and secondary endpoints. However, landmark analysis showed significant benefit in the primary endpoint for the DLT group after 200 days (hazard ratio [HR] 0.46, 95% confidence interval [CI] 0.22-0.93, P = 0.03). Landmark analysis also showed a significant benefit in the secondary endpoint in the DLT group within 200 days (HR 0.33, 95% CI 0.15-0.73, P = 0.006). Moreover, DLT improves the SAQ summary score, and scores in the physical limitation, treatment satisfaction, and disease perception domains for patients with ACS undergoing PCI. DLT combined with conventional treatment reduced the risk of the primary endpoint after 200 days and the secondary endpoint within 200 days during the 3-year follow-up. Additionally, DLT can improve the QOL without adverse effects.

Models optimized for real-world tasks reveal the task-dependent necessity of precise temporal coding in hearing.

Neurons encode information in the timing of their spikes in addition to their firing rates. Spike timing is particularly precise in the auditory nerve, where action potentials phase lock to sound with sub-millisecond precision, but its behavioral relevance remains uncertain. We optimized machine learning models to perform real-world hearing tasks with simulated cochlear input, assessing the precision of auditory nerve spike timing needed to reproduce human behavior. Models with high-fidelity phase locking exhibited more human-like sound localization and speech perception than models without, consistent with an essential role in human hearing. However, the temporal precision needed to reproduce human-like behavior varied across tasks, as did the precision that benefited real-world task performance. These effects suggest that perceptual domains incorporate phase locking to different extents depending on the demands of real-world hearing. The results illustrate how optimizing models for realistic tasks can clarify the role of candidate neural codes in perception.

Shared and distinct patterns of default mode network dysfunction in major depressive disorder and bipolar disorder: A comparative meta-analysis

BackgroundWhile patients with major depressive disorder (MDD) and bipolar disorder (BD) exhibited default mode network (DMN) dysfunction revealed by aberrant resting-state functional connectivity (rsFC) patterns, previous findings have been inconsistent. Little is known about the similarities and differences in DMN rsFC between MDD and BD. MethodsA voxel-wise meta-analysis of seed-based DMN rsFC studies on MDD or BD was performed using the Seed-based d Mapping software with permutation of subject images (SDM-PSI). Aberrant DMN rsFC in both disorders was investigated separately, followed by conjunction and between-disorder comparison analyses. Functional decoding was performed to implicate the psychophysiological underpinnings of derived brain abnormalities. ResultsThirty-four studies comparing 1316 MDD patients with 1327 HC, and 22 studies comparing 1059 BD patients with 1396 HC were included. Compared to HC, MDD patients exhibited DMN hyperconnectivity with frontolimbic systems, and hypoconnectivity with temporal lobe and posterior cingulate cortex. BD patients displayed increased DMN connectivity with bilateral precuneus, and reduced connectivity with prefrontal cortex and middle temporal gyrus. No common patterns of DMN rsFC abnormalities were observed between MDD and BD. Compared to BD, MDD patients showed DMN hyperconnectivity with triangular part of the left inferior frontal gyrus and left fusiform gyrus. Functional decoding found that patterns of DMN rsFC alteration between MDD and BD were primarily related to action and perception domains. ConclusionDistinct DMN dysfunction patterns in MDD and BD enhance current understanding of the neural substrates of mood disorders and may provide a potential biomarker for differentiation.

Understanding the Contributions of the Hippocampus

The hippocampus plays an important role in human memory, with its anterior portion contributing to coarse-grained representations and its posterior portion contributing to fine-grained ones (Poppenk et al., 2013). My USRA project is focused on understanding the role of the hippocampus in a potential third type of memory representation; a general synthesis of stimuli. Beyond memory, the hippocampus has also been hypothesize to influence clinical disorders. For instance, preliminary research in our lab has found meta-cognitive memory abilities to be organized into factors resembling clinical disorders, when organized by variance in brain structure. My USRA project also aims to understand the contribution of the hippocampus to clinical disorders. My role in this project has been to develop administrative and experimental structure for the protocol, which involves extensive testing. Participants will complete approximately 27 hours of memory tasks, designed to evaluate the nature of their memory, and whether it is oriented towards detail, gist, or a synthesis of all stimuli. To do so, I have developed an extensive task of reading and evaluating reviews, as well as a recall task of lab-generated stories. Participants will also complete approximately 3-4 hours of online questionnaires, administered through Qualtrics. Over the summer, I conducted research to identify validated questionnaires that assess metacognitive abilities, in the domains of memory, attention, language, motor control, social cognition and perception. Results on these questionnaires will be used to validate preliminary findings on the relationship between metacognitive memory, brain variance and sub-threshold levels of clinical disorders, and to investigate whether these findings expand to other forms of metacognition. Finally, participants will complete a number of structural and functional MRI scans (including DTI). This work may help us understand the pure science of the function of human memory, as well as the nature of clinical disorders.

Quality of Life, Its Determinants, and Psychiatric Comorbidities in Juvenile Myoclonic Epilepsy: A Cross-Sectional Observational Study From North India.

Juvenile myoclonic epilepsy (JME) is awell-controlled genetic generalized epilepsy (GGE) syndrome with a favourable prognosis but the long-term outcome is still controversial due to the presence of personality traits, executive dysfunction, and psychiatric disorders inherent to this condition. Also, the existing literature on quality of life (QoL) in adolescent patients of JME is sparse. This study was done to assess the QoL, its determinants, and the presence of psychiatric comorbidities in JME. The study was a hospital-based observational cross-sectional study of 50 participants done over 18 months. Patients of JME aged over 11 yearsfulfilling the diagnostic and electroencephalographic criteria were included in the study. Adolescentand adult JME participants were interviewed with the Quality of Life in Epilepsy-Adolescents-48 (QOLIE-AD-48) and patient-weighted Quality Of Life in Epilepsy-31 (QOLIE-31-P), respectively, for assessment of QoL, the domains affected, and its impact on overall QoL. They were also screened for psychiatric disorders with Mini International Neuropsychiatric Interview 7.0.2 (M.I.N.I. 7.0.2), a brief diagnostic-structured interview that has modules for each diagnostic category. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was used for further diagnostic categorization. Fifty patients with JME were enrolled. The mean age was 24.14 ± 7.7 years, of which 32 (64%) were female patients. The overall QOLIE-31-P score in adult JME participants was fair (62.29 ± 25.02). The impacted subdomains in adults were of seizure worry (47.73 ± 24.62) and cognitive functioning (46.41 ± 25.32). Themean QOLIE-48-AD score of adolescent JME study participants was fair (69.71 ± 13.13). The physical functioning (57.36 ± 18.94) and health perception (56.5 ± 16.9) domains were found to be impacted in adolescents. Five (10%) of the patients had anxiety and three (6%) of the participants had depression. A significant association was seen between the occurrence of generalized tonic-clonic seizure (GTCS) frequency (per year) and the presence of psychiatric comorbidity (p-value < 0.05). JME may have a negative impact on overall QoL in both adolescents and adults despite adequate seizure control. Fear of seizure recurrence, cognitive issues, negative perception of health, and comorbid psychiatric disorders need to be addressed simultaneously and treated holistically as part of comprehensive epilepsy care to improve long-term outcomes.

Adherence to CPAP Therapy in Obstructive Sleep Apnea: A Prospective Study on Quality of Life and Determinants of Use.

Obstructive sleep apnea (OSA) often goes unrecognized despite common symptoms, such as excessive daytime sleepiness, fatigue, and impaired quality of life (QoL). Continuous positive airway pressure (CPAP) is the gold standard treatment for OSA, but optimal daily usage and time needed for observable effects remain unclear. This study aimed to investigate the short-term effects of CPAP on daytime sleepiness and QoL in patients with severe OSA. Medical records were collected from 87 patients with severe OSA who initiated CPAP therapy. Also, validated questionnaires were used before and after one month of CPAP to analyze QoL-the Calgary Sleep Apnea Quality of Life Index (SAQLI), the Cues to CPAP Use Questionnaire (CCUQ), and daytime sleepiness-the Epworth Sleepiness Scale (ESS). Multiple regression analysis was conducted to identify predictors of CPAP usage. Of the total participants aged 55.6 ± 12.5, 77% were males, and 62% were CPAP adherent. Reductions in daytime sleepiness (ESS) were noted, as well as improvements in both overall QoL (SAQLI) and specifically in the domains of daily functioning, social interactions, emotional well-being, and symptom perception. Important cues for CPAP usage recognized by patients were physicians' instructions and physicians' concern regarding their patients' condition. Furthermore, multiple regression revealed higher SAQLI scores and lower ESS scores as positive predictors of CPAP usage, along with lower AHI after one month of CPAP being associated with sufficient adherence.

Effectiveness and Safety of Qishen Yiqi Dripping Pill in Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention: 3-Year Results from a Multicentre Cohort Study.

To evaluate the effectiveness and safety of Qishen Yiqi Dripping Pill (QSYQ) in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). This multicentre prospective cohort study was conducted at 40 centers in China. Patients with ACS after PCI entered either the QSYQ or Western medicine (WM) groups naturally based on whether they had received QSYQ before enrollment. QSYQ group received QSYQ (0.52 g, 3 times a day for 12 months) in addition to WM. The primary endpoint included cardiac death, non-fatal myocardial infarction, and urgent revascularization. The secondary endpoint included rehospitalization due to ACS, heart failure, stroke, and other thrombotic events. Quality of life was assessed by the Seattle Angina Questionnaire (SAQ). A total of 936 patients completed follow-up of the primary endpoint from February 2012 to December 2018. Overall, 487 patients received QSYQ and WM. During a median follow-up of 566 days (inter quartile range, IQR, 517-602), the primary endpoint occurred in 46 (9.45%) and 65 (14.48%) patients in QSYQ and WM groups respectively [adjusted hazard ratio (HR) 0.60, 95% confidence interval (CI) 0.41-0.90; P=0.013]. The secondary endpoint occurred in 61 (12.53%) and 74 (16.48%) patients in QSYQ and WM groups, respectively (adjusted HR 0.76, 95% CI 0.53-1.09; P=0.136). In sensitivity analysis, the results still demonstrated that WM combined with QSYQ reduced the risk of the primary endpoint (HR 0.67, 95% CI 0.46-0.98; P=0.039). Moreover, QSYQ improved the disease perception domain of the SAQ (P<0.05). In patients with ACS after PCI, QSYQ combined with WM reduced the incidence of the primary endpoint. These findings provide a promising option for managing ACS after PCI and suggest the potential treatment for reducing the risk of primary endpoint included cardiac death, non-fatal myocardial infarction, and urgent revascularization through intermittent administration of QSYQ (Registration No. ChiCTR-OOC-14005552).

Disease progression in Parkinson's disease patients with mild cognitive impairment: 5-year longitudinal study from the early Parkinson's disease longitudinal Singapore (PALS) cohort.

To investigate motor, non-motor and cognitive progression in early Parkinson's disease (PD) patients with Mild Cognitive Impairment (MCI). PD patients were recruited within 1 year of diagnosis and were classified into PD-MCI group and PD with normal cognition (PD-NC) group. H&Y staging scale, MDS-UPDRS part III were used to assess disease severity and motor progression. Non-motor symptom scale (NMSS) was used to evaluate the NMS progression. Cognitive progression was assessed from 5 cognitive domains. Annual progression changes in the longitudinal outcomes were examined via linear mixed model with random intercept effect. False discovery rate (FDR) method was performed to control for multiple testing comparison and q-value was calculated. We set the threshold of q-values as 0.1. A total of 205 PD patients, including 107 PD-MCI and 98 PD-NC patients were assessed prospectively over a 5-year period. PD-MCI patients, compared to PD-NC group, had a significantly higher progression rate in H&Y score (0.11 vs. 0.06, p=0.03, q=0.08), MDS-UPDRS motor score (3.11 vs. 1.90 p<0.001, q=0.06) and postural instability gait difficulty (PIGD) score (0.40 vs. 0.20, p=0.02, q=0.07). PD-MCI group also exhibited significantly faster deterioration in NMSS perceptual domain (PD-MCI vs. PD-NC: 0.38 vs. -0.04, p=0.01, q=0.06) and cognitive visuospatial domain (PD-MCI vs. PD-NC: 0.13 vs. -0.06, p=0.048, q=0.09) after adjustment for confounders and multiple comparisons. PD-MCI patients had faster decline in motor functions, visuo-perceptual and visuospatial performance. These findings provide a more comprehensive prognosis of PD-MCI, which could be helpful for clinician to manage PD-MCI patients.

Word formation patterns in the perception domain: a typological study of cross-modal semantic associations

Abstract The lexicalization of perception verbs has been of widespread interest as a route into understanding the relationship between language and cognition. A recent study finds global biases in colexification patterns, suggesting recurrent conceptual associations between sensory meanings across languages. In this paper, drawing on a balanced sample of 100 languages, we examine cross-modal semantic associations in word formation. Confirming earlier proposals, we find derived verbs are lower on a proposed Sense Modality Hierarchy (sight &gt; hearing &gt; touch &gt; taste, smell) than the source perception verbs on which they are based. We propose these findings can be explained by verb frequency asymmetries and the general tendency for sources of derivations to be more frequent than their targets. Moreover, it appears certain pairings (e.g., hear–smell) are recurrently associated via word formation, but others are typologically rare. Intriguingly, the typological patterning partially diverges from the patterning reported for colexification in the same domain. We suggest that while colexification is driven by conceptual resemblance between sensory meanings, cross-modal word formations tend to arise from grammaticalization processes of lexical specification, where additional material (e.g., a sensory noun) is collocated to a polysemous verb in order to disambiguate it in context. Together, these processes can account for the typological similarities and divergences between the two phenomena. More generally, this study highlights the need to consider conceptual, communicative and diachronic factors together in the mapping between words and meanings.

Developing Disability Advocates Through Deliberate Interprofessional Conversations Regarding Quality of Life After Stroke

ObjectiveStroke can result in significant mental and physical impairment. Training health care professionals on effective strategies for mitigating stroke-related quality-of-life issues is crucial in facilitating comprehensive stroke management. This study aimed to evaluate the impact of an interprofessional education (IPE) experience on students’ attitudes regarding poststroke disability. MethodsIn this pre-post interventional study, pharmacy and medical students received an electronic patient chart and a store-and-forward video depicting physical and cognitive impairment in a patient with stroke. Students were instructed to discuss the acute management and postdischarge needs of the patient from an advocacy perspective. After the IPE experience, students completed the Student Perceptions of Interprofessional Clinical Education-Revised, version 2 and an unvalidated disability attitudes survey. The surveys were analyzed using a paired t test. In addition, students reflected on the prompt, “What are some things you had NOT considered prior to this IPE?” ResultsA total of 708 students completed the surveys. After IPE, there was a significant improvement in all domains of the Student Perceptions of Interprofessional Clinical Education-Revised, version 2. On the disability survey, there was significant improvement on all statements, including “rate your comfort with…”: “discussing the expected disabilities associated with new-onset stroke” and “discussing strategies for improving the quality of life of a patient who has long-term disabilities.” On the self-reflections, 31.7% (n = 211) had not considered the need for poststroke care services before this IPE. ConclusionThis IPE experience was instrumental in improving student perspectives regarding poststroke disability.

Attitudes, perceptions, and perceived Barriers of undergraduate Dental Students in Learning and Understanding Statistics - A Qualitative Approach through Interviews

Introduction Given the critical role of statistics in the analysis and interpretation of scientific data, majority of health care students are expected to acquire the statistics knowledge as a part of their curriculum. Despite the focus on the pertinence of statistics, students continue to struggle with understanding them. Hence, a qualitative study was performed to explore the undergraduate dental students’ attitudes, perceptions and perceived barriers in learning and understanding statistics. Material and Methods Following purposive sampling technique, twenty-five undergraduate final year dental students were interviewed face to face or virtually using a standard general interview guide. The interviews were audio-taped and transcribed to verbatims. The data were subjected to descriptive and qualitative analysis to generate the themes by using the hybrid coding method. Results The mean age of the included participants was 23.12±1.013 years. The generated categories under the attitude component were interest, effort, difficulty, value and confidence. The themes generated under perception domain were content knowledge, importance, type of emotion and cognizance. The students opined that the barriers for learning and understanding statistics were related to time, curiosity, computation, teaching method and application. Conclusion The undergraduate dental students had an overall positive attitude towards statistics and their overall perception towards it was found to be good even though few of them had bad perception. The barriers reported by the students in learning and understanding statistics should be understood by the academic staff to make the student turn towards the desired direction by enhancing their skills.

Evolution of ambiguity tolerance research a scientometric and bibliometric analysis.

The present study conducts a retrospective bibliometric analysis to examine the quantifiable and qualitative evolution of the concept of tolerance to ambiguity (TA) over time. Additionally, a scientometric analysis using quantitative methods on scientific measurements and trends aims to profile and identify the concept, as well as its development in research themes. The relevance of this study is underscored by the growing interest and development of research on TA, particularly in fields like entrepreneurship where psychological factors are significant. The research includes highly relevant literature, such as Budner and Frenkel-Brunswick, which define TA as a predisposition to perceive ambiguous situations as desirable and as a personality variable centered on the emotional and perceptual domain, respectively. Data was obtained from the eight indices comprising the main Web of Science collection, covering research from 1975 to December 2022. A total of 378 articles were identified. The analysis reveals that scientific production peaked in 2022 with 45 articles. In terms of citations, 7,773 were found, with the highest concentration in 2022, totaling 1,203 citations. This indicates a significant increase in research interest and output related to TA. The study highlights the growing exploration of the concept of TA, emphasizing its importance across multiple disciplines in dealing with uncertainty. The research demonstrates that TA significantly influences decision-making and adaptability, highlighting its value in business and educational settings. By analyzing leading publications, authors, and research centers, the study shows the diversity of approaches to understanding TA, indicating a promising direction for future research.

Factors associated with self-rated health in people with late-stage parkinson’s and cognitive impairment

PurposeTo investigate the contributors to self-rated health in people with late-stage Parkinson’s disease (PD) and cognitive impairment.MethodsA secondary analysis of baseline data from the international Care of Late-Stage Parkinsonism (CLaSP) cohort study was conducted. Participants with PD and either dementia or mild cognitive impairment or MMSE < 24/30 in the absence of major depression were included if they had completed the EQ-5D-3L assessment (n = 277). Factors associated with self-rated health (EQ-5D-3L Index and Visual Analogue Scale) were investigated through multivariable linear regression.ResultsMore severe PD (motor and non-motor) was associated with worse self-rated health. The EQ-5D-3L dimensions of Mobility, Self-Care and Usual Activities were almost universally affected; the latter two particularly severely. Being unable to perform usual activities or having moderate to extreme anxiety or depression were significantly associated with EQ-5D-3L Visual Analogue Scale, suggesting these are particularly valued. Worse motor impairment and function and the non-motor symptom domains of mood, perception, sexual function, and miscellaneous (e.g., pain) were associated with worse self-rated health, whereas greater burden of gastrointestinal symptoms was associated with better self-rated health in multivariate analysis. Better self-rated health was associated with recent PD nurse consultation, and higher doses of dopaminergic medication.ConclusionImprovement of activities of daily living, mood and anxiety should be prioritised in clinical practice, with consideration of perception and sexual function in this population. Recent nurse consultations and higher antiparkinsonian doses are associated with better self-rated health, suggesting there is no room for a therapeutic nihilism in this population of people within a complex phase of PD.
