Towards a Personalized Seat Selection System of High-Speed Rail Based on Feasibility and Desirability

To conduct this research, we identified the current high-speed rail (HSR) market and passenger experience satisfaction with HSR. Then, we developed a personalized seat selection system that could assign passengers to different seats based on their own preferences by collecting their basic information. In the current HSR field, the existing research mainly focuses on improving hardware, such as seat comfort, high-speed rail traveling speed, and high-speed rail traveling smoothness. It does not consider travelers' environmental preferences and individual needs to a great extent. After several weeks of market research through the questionnaire and 4P model study, we concluded that the vast majority of passengers are dissatisfied with the current travel environment full of interruptions and are really willing to use a system that will improve their travel comfort. Therefore, the system will be added to a few major OTA platforms as a plug-in in order to reach a large number of potential customers. After that, we designed many features for our system based on the needs and interests of our target customers, as shown in the survey results, to confirm the desirability and feasibility of our product.

Characterizing the Adoption and Experiences of Users of Artificial Intelligence-Generated Health Information in the United States: Cross-Sectional Questionnaire Study.

OpenAI's ChatGPT is a source of advanced online health information (OHI) that may be integrated into individuals' health information-seeking routines. However, concerns have been raised about its factual accuracy and impact on health outcomes. To forecast implications for medical practice and public health, more information is needed on who uses the tool, how often, and for what. This study aims to characterize the reasons for and types of ChatGPT OHI use and describe the users most likely to engage with the platform. In this cross-sectional survey, patients received invitations to participate via the ResearchMatch platform, a nonprofit affiliate of the National Institutes of Health. A web-based survey measured demographic characteristics, use of ChatGPT and other sources of OHI, experience characterization, and resultant health behaviors. Descriptive statistics were used to summarize the data. Both 2-tailed t tests and Pearson chi-square tests were used to compare users of ChatGPT OHI to nonusers. Of 2406 respondents, 21.5% (n=517) respondents reported using ChatGPT for OHI. ChatGPT users were younger than nonusers (32.8 vs 39.1 years, P<.001) with lower advanced degree attainment (BA or higher; 49.9% vs 67%, P<.001) and greater use of transient health care (ED and urgent care; P<.001). ChatGPT users were more avid consumers of general non-ChatGPT OHI (percentage of weekly or greater OHI seeking frequency in past 6 months, 28.2% vs 22.8%, P<.001). Around 39.3% (n=206) respondents endorsed using the platform for OHI 2-3 times weekly or more, and most sought the tool to determine if a consultation was required (47.4%, n=245) or to explore alternative treatment (46.2%, n=239). Use characterization was favorable as many believed ChatGPT to be just as or more useful than other OHIs (87.7%, n=429) and their doctor (81%, n=407). About one-third of respondents requested a referral (35.6%, n=184) or changed medications (31%, n=160) based on the information received from ChatGPT. As many users reported skepticism regarding the ChatGPT output (67.9%, n=336), most turned to their physicians (67.5%, n=349). This study underscores the significant role of AI-generated OHI in shaping health-seeking behaviors and the potential evolution of patient-provider interactions. Given the proclivity of these users to enact health behavior changes based on AI-generated content, there is an opportunity for physicians to guide ChatGPT OHI users on an informed and examined use of the technology.

Sensory symptoms associated with autistic traits and anxiety levels in children aged 6–11 years

BackgroundAutism spectrum conditions (ASC) and quantitative autistic traits (QATs) are associated with sensory symptoms, which may contribute to anxiety and adversely affect social and cognitive development. Although sensory symptoms can occur across all senses, the relative roles of specific sensory modalities as contributors to the autistic phenotype and to anxiety are not well understood. The objective of this study was to examine which sensory symptoms were most predictive of high anxiety.MethodsWe recruited 257 female primary caregivers of children aged 6 to 11 years (49% girls) to a questionnaire study comprising parent-report measures for classical QATs (social, communicative, and rigid), autism-related sensorimotor symptoms (visual, auditory, tactile, olfactory, gustatory, vestibular, proprioceptive, and motor), and anxiety symptoms. First, Bayesian stochastic search variable selection (SSVS) was used to identify the most probable sensorimotor predictors of specific QATs as well as diagnosed ASC. Then, the selected predictors were used in another SSVS, using anxiety symptoms as a dependent variable, to identify which of the autism-relevant sensorimotor symptoms were most robustly predictive of anxiety. Finally, the effect sizes of anxiety-related sensory symptoms were estimated with linear regressions.ResultsWe found that auditory symptoms and motor difficulties were most predictive of ASC diagnosis. Developmental motor difficulties were also strongly related to all individual QATs, whereas auditory symptoms were more selectively predictive of rigid traits. Tactile symptoms robustly predicted social interaction QATs, and proprioceptive symptoms predicted communicative QATs. Anxiety outcomes were most strongly predicted by difficulties with auditory and olfactory processing.ConclusionsThe results support the clinical importance of being alert to complaints about sounds and hearing in neurodevelopmental populations, and that auditory processing difficulties may be evaluated as an early marker of poor mental health in children with and without diagnosed autism. Olfactory processing differences appeared to be an anxiety marker less strongly associated with ASC or QATs, while motor difficulties were highly autism-relevant but not equally strongly associated with anxiety outcomes. We suggest that future studies may focus on the mechanisms and consequences of neurodevelopmental central auditory processing dysfunction and its potential relationship to anxiety disorders.

Gasless trans-axillary endoscopic versus conventional open hemithyroidectomy for thyroid cancer patients: A propensity score-matched analysis of quality of life and oncological outcomes: A cross-sectional questionnaire study

BackgroundThyroid cancer predominantly affects young females who seek surgical intervention not only for excellent oncological outcomes but also for a high quality of life (QOL) and favorable cosmetic and functional outcomes. The gasless trans-axillary endoscopic (GTAE) approach is a commonly used remote access technique for thyroid surgeries. It holds the potential for comparable oncological outcomes and superior QOL, cosmetic, and functional outcomes. However, robust evidence supporting this hypothesis is scarce. Materials and MethodsWe collected data from patients diagnosed with papillary thyroid carcinoma who underwent hemithyroidectomy with central compartment dissection at Peking Union Medical College Hospital (PUMCH) between December 2019 and January 2023. After applying propensity-score matching analysis (PSMA), a total of 424 cases were included. For oncological outcomes, patients in both groups were prospectively followed through regular outpatient visits. The QOL, functional, and cosmetic outcomes were assessed using a cross-sectional online questionnaire, including EORTC-THY34 for QOL, PSAQ for cosmetic outcomes, SIS-6 for swallowing functions, and VHI-10 for voicing functions. We further compared oncological outcomes, QOL, functional, and cosmetic outcomes between these two groups. ResultsA total of 274 cases provided validated responses: 141 underwent the GTAE approach, and 134 underwent the conventional open (CO) approach. The operation time was approximately 60 minutes longer in the GTAE group. Notably, there was no difference in complications between the two approaches. Rates of suspicious recurrence in both groups remained low and showed no significant differences (2.55% vs. 1.57%, p>0.05). No pathological confirmed recurrence was reported in either group. Patients with the GTAE approach showed better body image and less joint pain (EORTC-THY34), better swallowing (SIS-6), and better cosmetic outcomes (PSAQ). Voice outcomes showed no difference between these two approaches (VHI-10). ConclusionCompared to the CO approach, hemithyroidectomy with central compartment dissection via the GTAE approach in low-risk patients maintains comparable oncological outcomes while offering better QOL, cosmetic benefits, and functional outcomes.

Research on the Working Path of Adolescent Psychological Health Education Under the Background of China&amp;apos;s New Education Reform

Adolescence is a critical period for rapid development in behavior, personality, and intelligence. Currently, the frequent occurrence of psychological crises among Chinese adolescents is detrimental to the comprehensive development of talents, the implementation of quality-oriented education, and the harmonious development of society. Based on multi-level questionnaire surveys and interview studies, this paper finds that China&amp;apos;s education sector is increasingly emphasizing psychological health education for adolescents, continuously improving supporting mechanisms. The initial system of psychological health services in schools has taken shape, with psychological health training benefiting both schools and families, and autonomous attention from adolescents groups has increased. However, issues persist, including inadequate psychological health curricula, incomplete linkage mechanisms, imperfect family support, insufficient teacher staffing and re-education training, and inadequate identification and rescue of students&amp;apos; psychological crises. Therefore, this paper argues that systematically and deeply promoting the multi-faceted psychological health education model of &amp;quot;family-school-society,&amp;quot; adopting multiple measures to collaboratively build and optimize coordination mechanisms, and establishing a more robust and effective approach to adolescent psychological health work, aligns with the direction of educational evaluation reform in the new era, fosters a favorable social atmosphere, and is the inevitable path to better promote the healthy growth and talent development of adolescents.

Internalized racism, racial collective self-esteem, and Asian American adults’ disordered eating: Psychological distress as mediator

Research emphasizes the importance of considering how sociocultural factors affect the disordered eating behaviors of Asian American adults. The present study thus investigated how internalized racism and racial collective self-esteem are associated with disordered eating among Asian American adults, as well as the potential mediating role of psychological distress. A final sample of 796 Asian American adults completed a cross-sectional survey that contained the study's questionnaires. Regression analyses revealed that internalized racism was positively associated with disordered eating, whereas racial collective self-esteem was negatively associated with disordered eating among Asian American adults. Psychological distress mediated both of the aforementioned associations. Researchers and practitioners are encouraged to be cognizant about how Asian American adult clients' experiences of internalized racism and psychological distress may affect their disordered eating. Researchers and practitioners may also strive to increase racial collective self-esteem among this population. Future researchers may consider building upon these findings by conducting longitudinal research or focusing on specific Asian ethnic groups for further studies about disordered eating among Asian Americans.

Questionnaire Development to Assess Risk Factors for Environmental Diseases of Children in Daejeon.

Background: Allergic diseases are common in children and adolescents. It is important to assess the prevalence and risk factors of environmental diseases to implement tailored countermeasures. Methods: This questionnaire study investigated factors associated with environmental diseases in elementary school children with an environmental disease from 150 households in Daejeon Metropolitan City, South Korea in 2021. Results: The participants comprised 55.7% girls and 44.3% boys, and the mean age was 10.1 years with an even age distribution. The typical risk factors observed were the type of roads nearby, the presence of mold or stains within the residence, pet ownership, and frequency of indoor ventilation and cleaning. Notably, 73.2% of the households had an eight-lane road nearby, 40.2% reported leaks, stains, or mold within their homes during the past year, and 37.1% ventilated their homes for less than 30 min. After education on preventing and managing environmental diseases, significant changes were observed in bedding washing frequency, average ventilation duration per session, and duration of humidifier usage (p < 0.05-0.001), with improvements in lifestyle. Conclusions: Our study can be used as a reference for expanding indoor air quality control education for parents with children with an environmental disease and providing tailored environmental consultations.

The awareness of enhanced recovery after surgery (ERAS) cesarean delivery guidelines among anesthesiology and reanimation assistants in Turkey; a questionnaire study

BackgroundTo reduce maternal-fetal morbidity and mortality, it is becoming increasingly important for anesthetists to understand and implement enhanced recovery after surgery (ERAS) cesarean delivery guidelines. Our aim was to reveal the knowledge of anesthesia assistants in Turkey about ERAS during cesarean delivery and to increase their awareness of ERAS.MethodsThis descriptive study was conducted in the city of Isparta, Turkey in 2023. The survey, which was approved by the ethics committee, was distributed to participants across Turkey via e-mail and online messages. The survey comprises of a total of 42 questions evaluating perioperative ERAS recommendations.ResultsOf the 404 participants in our survey, 59.9% were associated with university hospitals and 65.8% had completed three or more years of education. A total of 87.9% of the participants were familiar with ERAS; however, only 42.8% had received ERAS training. Although 93.8% of the participants’ institutions performed a cesarean delivery, ERAS recommendations were only implemented at a rate of 48%. This may be due to the absence of an ERAS team, which was identified in our survey at a high rate of 66.6%.ConclusionAwareness about ERAS was high among the participants, but the implementation rates of some recommendations were low. The reason for this may be the inability to form a multidisciplinary team and inadequate training of participants. For this purpose, we recommend the formation of a multidisciplinary team for ERAS protocol implementation and increased participant training opportunities.

Development of a self-assessment tool to address the functioning of community-dwelling older adults in general practice: a validation study of the EFA23 questionnaire

BackgroundMultimorbidity is increasingly prevalent among ageing patients, leading to reduced daily functioning. To address the challenges posed by multimorbidity in older adults, a person- and context-centred approach is needed. This study aimed to develop a questionnaire as a self-assessment tool for older adults focusing on functioning in general practice based on the International Classification of Functioning, Disability and Health (ICF).MethodsA mixed-methods approach was employed in the development and validation of the German EFA23 (Erfassung Funktionaler Gesundheit im Alter – 23 Fragen; Assessing Functional Health in Old Age – 23 questions) questionnaire. Based on an ICF subset developed in a preparatory phase and consensus study, questionnaire items were formulated and tested in a qualitative pretest, followed by a validation study. A workshop with general practitioners (GPs) was held to develop a supplementary manual for GPs on how to interpret the questionnaire results and discuss them with the patients.ResultsA total of 69 items were developed and tested in the qualitative pretest with 15 respondents, resulting in 37 items for the validation study. The validation study, involving 237 older adults, showed the presence of one significant principal component. It demonstrated good internal consistency (Cronbach’s alpha = 0.967) and construct validity, showing positive correlations with established assessment tools. Descriptive statistics showed differences between the means of self-assessment by patients and an external GP assessment. The final EFA23 questionnaire consists of 23 items assessing limitations in functioning.ConclusionsThe EFA23 questionnaire can be used as a valid self-assessment instrument to measure functioning in older adults, supporting a person- and context-centred approach in general practice.

The role of mindfulness in stress, productivity and wellbeing of foundation year doctors: a mixed-methods feasibility study of the mindful resilience and effectiveness training programme

BackgroundMedical Foundation Year (FY) doctors demonstrate greater psychological distress compared with the general population and other student groups. This feasibility study investigated FY doctors’ perceptions of mindfulness and the impact of a mindful resilience and effectiveness training (MRET) programme on stress, wellbeing, and performance.MethodsMixed-methods study utilising a questionnaire (study 1, N = 144) and a pre-post analysis design of MRET programme (study 2, N = 13), along with focus groups (N = 7).ResultsIn study 1 28.5% of FY’s reported using mindfulness. All five mindfulness facets were significantly, and positively, associated with mental wellbeing (p < 0.05). Acting with awareness (AA) and non-reactivity (NR) were significantly, positively associated with a challenge responses to stress (p < 0.05). Threat and loss appraisals were negatively associated with AA, NR, and non-judging (p < 0.01). Perceived productivity was positively associated with mindfulness facets: describing, AA, and NR (p < 0.001). In study 2, there were significant increases in wellbeing and mindfulness facets observing, describing, AA, and NR, and threat appraisals decreased (p < 0.05). The main themes identified across the focus group included Reframed Mindset, Values-Based Action, Embodied Leadership and Pedagogy.ConclusionsThere exists a relationship between mindfulness, psychological wellbeing, and performance in FYs. The MRET prorgamme improved psychological wellbeing and reduced threat appraisals. Future work could focus resources on enhancing the skills of AA and NR, as this may be sufficient to bring about meaningful improvements in wellbeing, percieved productivity and cognitive reappraisal of stressful life events.

Trends in the treatment of human papillomavirus-associated oropharyngeal carcinoma in Slovakia.

The optimal treatment of oropharyngeal cancer (OPC) associated with human papillomavirus (HPV) is currently a subject of clinical research. This questionnaire study investigated current trends in the treatment of HPV-associated (HPV+) OPC in Slovakia with the incorporation of deintensification of oncological treatment into routine clinical practice outside of clinical trials. The Slovak Cooperative Head and Neck Cancer Group (SCHNCG) developed a questionnaire aimed at identifying trends in the oncological treatment of HPV+ OPC intended for all radiation oncology (RO) facilities in Slovakia. Specialists in the field of RO responded to general questions about the character of their individual institutions as well as to 4 theoretical clinical scenarios (case reports) regarding the treatment of HPV+ OPC, focusing primarily on the applied dose of radiotherapy (RT), the extent of target volumes, and the type of concurrent chemotherapy (CHT). The questionnaire study involved 35 RO specialists from 14 institutions in Slovakia. Regarding primary chemoradiotherapy (CRT) in T1N1M0 HPV+ OPC, 16 respondents (45.7%) would consider de-escalation of the RT dose to <70 Gy. In the case of postoperative RT in pT1pN1M0 HPV+ OPC with negative resection margins (R0) and absent extracapsular extension (ECE), 4 physicians (11.4%) would consider de-escalation of the RT dose to <60 Gy in the tumor bed area, while the majority of the treating specialists (n=19, 54.3%) would omit concurrent CHT. In the case of primary RT in elderly patient with T2N1M0 HPV+ OPC, the same number of physicians (n=16, 45.7%) would consider de-escalation of the RT dose to <70 Gy, and 14 respondents (40.0%) would completely omit CHT. In a high-risk patient with T2N3M0 HPV+ OPC with a complete response after 3 cycles of induction chemotherapy (iCHT), none of the respondents would indicate a reduction in the RT dose to the area of the original tumor and lymphadenopathy to <60 Gy. The doses and extent of irradiated volumes in the treatment of HPV+ OPC in Slovakia vary among different institutions. The tendency to de-escalate RT doses and reduce doses of concurrent systemic therapy in Slovakia is high and there was also an observed trend to reduce the extent of radiation treatment fields.

Factors related to the disaster preparedness of patients on haemodialysis from Sichuan, China, during COVID-19: A cross-sectional study.

This study aimed to investigate personal preparedness among patients on haemodialysis (HD) and to examine the relationship among sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours during natural disaster incidents. A cross-sectional survey was conducted. A convenience sampling method was used. A total of 446 participants from six areas of Sichuan province completed the online questionnaire study from February 27 to March 13, 2022. Sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours were measured. Descriptive statistics were used to analyse sociodemographic characteristics and attitudes toward disaster preparedness. The relationship among sociodemographic characteristics, attitudes toward disaster preparedness and personal preparedness behaviours were assessed using ordinal regression. Statistical significance was defined as p < 0.05. A total of 446 participants completed the survey. Of these, 42.15% (N = 188) were poorly prepared, 26.23% (N = 117) were moderately prepared and 31.61% (N = 141) were highly prepared. Ordinal regression showed that knowing about disaster preparedness (Odds Ratio (OR) = 1.691, 95% Confidence Interval (CI) = 1.081-2.644, p = 0.021), participating in disaster evacuation exercises (OR = 2.519, 95% CI = 1.595-3.977, p < 0.001) and learning about disaster preparedness (OR = 2.421, 95% CI = 1.542-3.802, p < 0.001) were associated with high preparedness. Compared to patients with a university degree or higher, patients with a junior high school education or lower (OR = 3.491, 95% CI = 1.760-6.925, p < 0.001) and senior high school degree (OR = 2.052, 95% CI = 1.038-4.057, p = 0.039) were associated with high preparedness. Patients who felt very confident and could deal with all their needs (OR = 3.878, 95% CI = 2.904-7.181, p < 0.001) or patients who felt confident and could meet some of their needs (OR = 1.949, 95% CI = 1.124-3.379, p = 0.017) had higher preparedness than those who felt less confident and were not well prepared to take care of their needs. After obtaining each participant's consent, they filled out the online questionnaire using their own or a relative's cell phone while undergoing HD. It is essential that patients should be educated not only on medical specialty topics, but also on general disaster preparedness. Medical institutions should improve and reinforce preparation training among targeted populations. The low level of preparedness is partly due to the lack of participation of patients in disaster preparedness programs. Dialysis center managers should be urged to implement such programs at their centers.

Post hoc analysis of the characteristics and treatment needs of patients with dementia with Lewy bodies (DLB) and their caregivers and their physicians' awareness of those treatment needs according to the duration after diagnosis of DLB.

To investigate the differences in patient/caregiver characteristics, their treatment needs, and the attending physician's understanding of those treatment needs according to the duration after diagnosis of dementia with Lewy bodies (DLB). This was a post hoc analysis of a multicenter, cross-sectional, questionnaire survey study. A total of 263 patient-caregiver pairs were reclassified into two groups according to the median duration after diagnosis of DLB as follows: short (<24months; S-group) and long (≥24months; L-group) post-DLB diagnosis duration. Treatment need was defined as the symptom domain that caused the patient or caregiver the most distress. Concordance rates between patient-physician and caregiver-physician were calculated for physicians' understanding of treatment needs. In this analysis, 126 pairs (32 physicians) and 137 pairs (34 physicians) were classified as the S- and L-groups, respectively. Patient and caregiver characteristics were broadly similar between groups (mean age for patients 78.7±6.6 vs. 79.8±6.7, for caregivers 64.7±12.9 vs. 64.9±12.8; number of male/female for patients 61/65 vs. 67/70, for caregivers 34/92 vs. 38/99), but the prevalence of parkinsonism (82.5% vs. 66.7%) and autonomic dysfunction (49.6% vs. 33.3%), severity of parkinsonism (MDS-UPDRS Part III total scores, 29.2±22.6 vs. 18.0±16.4; Part II total score, 14.6±12.0 vs. 7.6±7.9), and caregiver burden (J-ZBI_8 score, 9.1±6.7 vs. 7.5±5.8) were higher in the L-group than the S-group. Regarding treatment needs, the invalid answer rates for patients were 34.9% and 46.8%, and those for caregivers were 28.6% and 34.9% in the S- and L groups, respectively. Patients' treatment needs did not significantly differ (p=0.056), but S-group patients were more likely to select cognitive impairment (p=0.045) as their treatment need, whereas L-group patients were more likely to select parkinsonism (p=0.003). Caregivers' treatment needs significantly differed (p=0.032) between groups. S-group caregivers were more likely to select cognitive impairment (p=0.001), whereas L-group caregivers were more likely to select other symptom domains such as parkinsonism (S-group vs. L-group: 10.3% vs. 16.7%), psychiatric symptoms (20.6% vs. 24.6%), sleep-related disorder (4.0% vs. 7.1%), and autonomic dysfunction (4.8% vs. 9.5%). Concordance rates between patient-physician and caregiver-physician were low in both groups. There were some differences in characteristics according to the duration after diagnosis of DLB. Cognitive dysfunction may be a particular concern for patients and caregivers soon after diagnosis of DLB. Treatment needs of patients and caregivers for parkinsonism, psychiatric symptoms, sleep-related disorder, or autonomic dysfunction were different according to the duration after diagnosis of DLB. Physicians' perception of patients'/caregivers' treatment needs was poor regardless of the duration after diagnosis of DLB. UMIN Clinical Trials Registry (UMIN000041844).

Periodontal microbiology from undergraduate perspective: a questionnaire study

Background: Periodontal diseases are inflammatory conditions affecting the supporting structure of the teeth, leading to potential consequences such as gingivitis and periodontitis. The intricate interaction between host’s immune system and oral microbiome promotes this disease. The human oral cavity harbors a vast and diverse microbial community, collectively known as the oral microbiome comprising of bacteria, viruses, fungi, this ecosystem is influenced by factors such as genetics, host immunity, oral hygiene practices, diet and environmental variables. Among these microorganisms, bacteria take center stage in the initiation and progression of periodontal diseases. The objective was to assess the knowledge and awareness about the periodontal microbiology (periopathogens) among dental students. Methods: A self-designed questionnaire in English language containing 26 items was circulated using Google forms and was distributed among third, final year students and interns of PMNM dental college and Hospital, Bagalkot, India. The framework covered 3 domains: The first domain containing microorganism’s interaction in host causing periodontal disease, second domain about colonizers in dental plaque and certain aspects covered inflammatory response in host and the third domain containing therapeutic planning and future perspectives. Results: When looked into 1st domain student had a good knowledge on microorganism interaction in host, student had fair knowledge about the 2nd domain, they lack knowledge about the 3rd domain that is about therapeutic planning. Conclusions: Student have a fair knowledge about the periodontal pathogen and they lack knowledge about the therapeutic planning. It is indicative of students’ commitment to understanding the complex dynamics of oral microbiology.

Assessment of Knowledge and Utilization of Prefabricated Band and Loop Space Maintainers in Primary Dentition Among Dentists: A Cross-Sectional Questionnaire Study.

Preserving primary dentition is essential for maintaining optimal oral health and development in children. Premature loss of primary teeth due to caries, infection, crowding, or trauma can necessitate orthodontic intervention and lead to various complications. Space maintainers are critical for preserving arch space until the eruption of permanent teeth, thereby preventing issues such as ectopic eruption, crowding, and malocclusion. Despite their advantages, prefabricated space maintainers (PSMs) are underutilized. This study aims to evaluate the knowledge, attitudes, and practices of Indian dentists regarding PSMs in primary teeth. A cross-sectional questionnaire survey was conducted among 100 dental practitioners in Chennai. A 10-item self-administered questionnaire, developed based on a comprehensive literature review and expert consultations, assessed demographics, knowledge of PSM indications and techniques, current practices, perceived barriers, and preferences for continuing education. The questionnaire's reliability was confirmed with a Cronbach's alpha value of 0.85. Descriptive statistics, including frequencies andpercentages, were used to summarize the participants' demographic characteristics, knowledge levels, and current practices related to PSMs. Of the 100 respondents, 86 (86%) were males and 14 (14%) were females. Only 19 (19%) reported using PSMs, while 36 (36%) used conventional space maintainers. A significant proportion (42 (42%)) of the respondents held a master's degree in dental surgery, yet only 11 (11%) had participated in Continuing Dental Education (CDE) programs on space maintainers. The perceived benefit of PSMs being a single appointment procedure was acknowledged by 82 (82%) of the respondents, whereas 76 (76%) participants identified cost as a major drawback. Notably, 45 (45%) practitioners did not consider PSMs necessary. This survey highlights notable obstacles in the adoption of PSMs among Indian dentists, emphasizing the need for focused educational initiatives. Improving knowledge and practices related to PSMs can enhance pediatric dental care and oral health outcomes in India.

Use of Machine Learning Models to Differentiate Neurodevelopment Conditions Through Digitally Collected Data: Cross-Sectional Questionnaire Study.

Diagnosis of child and adolescent psychopathologies involves a multifaceted approach, integrating clinical observations, behavioral assessments, medical history, cognitive testing, and familial context information. Digital technologies, especially internet-based platforms for administering caregiver-rated questionnaires, are increasingly used in this field, particularly during the screening phase. The ascent of digital platforms for data collection has propelled advanced psychopathology classification methods such as supervised machine learning (ML) into the forefront of both research and clinical environments. This shift, recently called psycho-informatics, has been facilitated by gradually incorporating computational devices into clinical workflows. However, an actual integration between telemedicine and the ML approach has yet to be fulfilled. Under these premises, exploring the potential of ML applications for analyzing digitally collected data may have significant implications for supporting the clinical practice of diagnosing early psychopathology. The purpose of this study was, therefore, to exploit ML models for the classification of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) using internet-based parent-reported socio-anamnestic data, aiming at obtaining accurate predictive models for new help-seeking families. In this retrospective, single-center observational study, socio-anamnestic data were collected from 1688 children and adolescents referred for suspected neurodevelopmental conditions. The data included sociodemographic, clinical, environmental, and developmental factors, collected remotely through the first Italian internet-based screening tool for neurodevelopmental disorders, the Medea Information and Clinical Assessment On-Line (MedicalBIT). Random forest (RF), decision tree, and logistic regression models were developed and evaluated using classification accuracy, sensitivity, specificity, and importance of independent variables. The RF model demonstrated robust accuracy, achieving 84% (95% CI 82-85; P<.001) for ADHD and 86% (95% CI 84-87; P<.001) for ASD classifications. Sensitivities were also high, with 93% for ADHD and 95% for ASD. In contrast, the DT and LR models exhibited lower accuracy (DT 74%, 95% CI 71-77; P<.001 for ADHD; DT 79%, 95% CI 77-82; P<.001 for ASD; LR 61%, 95% CI 57-64; P<.001 for ADHD; LR 63%, 95% CI 60-67; P<.001 for ASD) and sensitivities (DT: 82% for ADHD and 88% for ASD; LR: 62% for ADHD and 68% for ASD). The independent variables considered for classification differed in importance between the 2 models, reflecting the distinct characteristics of the 3 ML approaches. This study highlights the potential of ML models, particularly RF, in enhancing the diagnostic process of child and adolescent psychopathology. Altogether, the current findings underscore the significance of leveraging digital platforms and computational techniques in the diagnostic process. While interpretability remains crucial, the developed approach might provide valuable screening tools for clinicians, highlighting the significance of embedding computational techniques in the diagnostic process.

Positive health: An integrated quantitative approach in patients with chronic gastrointestinal and hepato-pancreatico-biliary disorders.

The concept of positive health (PH) supports an integrated approach for patients by taking into account six dimensions of health. This approach is especially relevant for patients with chronic disorders. Chronic gastrointestinal and hepato-pancreatico-biliary (GI-HPB) disorders are among the top-6 of the most prevalent chronically affected organ systems. The impact of chronic GI-HPB disorders on individuals may be disproportionally high because: (1) The affected organ system frequently contributes to a malnourished state; and (2) persons with chronic GI-HPB disorders are often younger than persons with chronic diseases in other organ systems. To describe and quantify the dimensions of PH in patients with chronic GI-HPB disorders. Prospective, observational questionnaire study performed between 2019 and 2021 in 235 patients with a chronic GI-HPB disorder attending the Outpatient Department of the Maastricht University Medical Center. Validated questionnaires and data from patient files were used to quantify the six dimensions of PH. Internal consistency was tested with McDonald's Omega. Zero-order Pearson correlations and t-tests were used to assess associations and differences. A P value < 0.05 was considered significant. The GI-HPB patients scored significantly worse in all dimensions of PH compared to control data or norm scores from the general population. Regarding quality of life, participation and daily functioning, GI-HPB patients scored in the same range as patients with chronic disorders in other organ systems, but depressive symptoms (in 35%) and malnutrition (in 45%) were more frequent in patients with chronic GI-HPB disorders. Intercorrelation scores between the six dimensions were only very weak to weak, forcing us to quantify each domain separately. All six dimensions of PH are impaired in the GI-HPB patients. Malnutrition and depressive symptoms are more prevalent compared to patients with chronic disorders in other organ systems.

Factors associated with medical students’ career choice in different specialties: a multiple cross-sectional questionnaire study at a German medical school

BackgroundGiven the shortage and unequal distribution of physicians across specialties, we aimed to evaluate factors associated with medical students’ career choices, including background, personality traits, educational experience, personal interests, lifestyle considerations, and the awareness of work requirements.MethodsWe conducted multiple cross-sectional surveys of students; a 159-item online questionnaire was designed and students from three different stages of the six-year medical degree course (outset, clinical phase, and on graduation) were invited to complete the survey. Data were collected between May 2021 and April 2023.ResultsThe questionnaire was sent to 1406 students, of whom 683 replied (49%); 481 respondents were female (70%). The top specialty choices across the respondents were internal medicine, surgery, and general practice, with anaesthesiology, paediatric and adolescent medicine (ranging 11–15%), and obstetrics and gynaecology also receiving interest, with 6% undecided. In particular, female students lost interest in surgery during the course of study in favour of the other options. The choice of general practice was associated with more vocational training, prior positive experiences with the specialty, and lower grades in the university entry examination. Clinical clerkships in a specific (freely chosen) specialty aligned with career choice, while the final practical year did not have an impact on career decision-making. All students highly desired regulated working hours and work-life-balance; however, students choosing surgery rated these items as less important. Willingness to work in a hospital environment was highly associated with choosing anaesthesiology and surgery, whereas rural areas and practices were associated with general practice. Higher scores at agreeableness were associated with choosing paediatric and adolescent medicine by more female students, whereas lower neuroticism values were associated with the choice of anaesthesiology.ConclusionsThe results highlight the intricate nature of decision-making and shed light on various aspects that contribute to the process of selecting a specialty. By identifying and addressing influencing factors, we can develop targeted interventions and policies to enhance diversity and distribution across medical specialisations and to aim for high-quality and equitable healthcare that matches the specific needs of both individuals and the population as a whole.Graphical

Nonbinary Voices for Digital Assistants—An Investigation of User Perceptions and Gender Stereotypes

Due to the wide adoption of digital voice assistants (DVAs), interactions with technology have also changed our perceptions, highlighting and reinforcing (mostly) negative gender stereotypes. Regarding the ongoing advancements in the field of human–machine interaction, a developed and improved understanding of and awareness of the reciprocity of gender and DVA technology use is thus crucial. Our work in this field expands prior research by including a nonbinary voice option as a means to eschew gender stereotypes. We used a between-subject quasi-experimental questionnaire study (female voice vs. male voice vs. nonbinary voice), in which n=318 participants provided feedback on gender stereotypes connected to voice perceptions and personality traits. Our findings show that the overall gender perception of our nonbinary voice leaned towards male on the gender spectrum, whereas the female-gendered and male-gendered voices were clearly identified as such. Furthermore, we found that feminine attributes were clearly tied to our female-gendered voice, whereas the connection of masculine attributes to the male voice was less pronounced. Most notably, however, we did not find gender-stereotypical trait attributions with our nonbinary voice. Results also show that the likability of our female-gendered and nonbinary voices was lower than it was with our male-gendered voice, and that, particularly with the nonbinary voice, this likability was affected by people’s personality traits. Thus, overall, our findings contribute (1) additional theoretical grounding for gender-studies in human–machine interaction, and (2) insights concerning peoples’ perceptions of nonbinary voices, providing additional guidance for researchers, technology designers, and DVA providers.
