ABSTRACT

BACKGROUND: Autism spectrum disorders are a type of developmental disorder that primarily disrupt social interactions and communications. Autism has no treatment, but early diagnosis of it is crucial to reduce these effects. The incidence of autism is represented in repetitive patterns of children’s motion. When walking, these children tighten their muscles and cannot control and maintain their body position. Autism is not only a mental health disorder but also a movement disorder.

METHOD: This study aims to identify autistic children based on data recorded from their gait patterns using a Kinect sensor. The database used in this study comprises walking information, such as joint positions and angles between joints, of 50 autistic and 50 healthy children. Two groups of features were extracted from the Kinect data in this study. The first one was statistical features of joints’ position and angles between joints. The second group was the features based on medical knowledge about autistic children’s behaviors. Then, extracted features were evaluated through statistical tests, and optimal features were selected. Finally, these selected features were classified by naïve Bayes, support vector machine, k-nearest neighbors, and ensemble classifier.

RESULTS: The highest classification accuracy for medical knowledge-based features was 87% with 86% sensitivity and 88% specificity using an ensemble classifier; for statistical features, 84% of accuracy was obtained with 86% sensitivity and 82% specificity using naïve Bayes.

CONCLUSION: The dimension of the resulted feature vector based on autistic children’s medical knowledge was 16, with an accuracy of 87%, showing the superiority of these features compared to 42 statistical features.

ABSTRACT

OBJECTIVES: Extracurricular activities (EA) are crucial for medical education, fostering professional and personal growth. They complement formal curriculum structures, addressing students’ social, psychological, and academic needs. Understanding students’ motivations for choosing EA is essential for creating effective educational strategies. Our study examined medical students’ engagement in EA, focusing on the most common activities, perceived importance, and the motivations and challenges faced.

METHODS: This was a cross-sectional study, employing both quantitative and qualitative designs, involving a convenience sample of medical students from Brazil. Data collection was carried out using an anonymous, structured electronic form to gather information on the sociodemographic profile of students and aspects related to EA participation. The analysis included both descriptive statistics and qualitative content analysis, providing detailed insights into student motivations and their experiences with EA.

RESULTS: Out of 221 study participants, 82.4% were actively involved in EA. Sports (44.8%), scientific events (39.4%), artistic activities (33.5%), and participation in scientific programs (28.1%) were prominent choices, with students dedicating 8.5 h per week. Students under the age of 28 (P = .017) and those without a previous academic degree (P = .036) showed a higher frequency of involvement in EA, as confirmed by logistic regression analysis revealing significant associations for these variables (OR = 1.16, 95% CI: 1.02-1.32, P = .017; and OR = 0.88, 95% CI: 0.78-1.00, P = .036, respectively). Motivations for EA participation were primarily driven by a desire to enhance curriculum vitae and develop essential professional skills. Challenges such as time management and academic adjustment were common among medical students.

CONCLUSIONS: Our findings highlight the widespread involvement of medical students in EA, illustrating a diverse range of interests. Younger students and those without previous academic training are more likely to participate. Motivations include enriching the curriculum and refining skills, yet challenges such as time management and adjusting to academic demands are significant, especially for new students.

ABSTRACT

BACKGROUND: There was less research about cytokines in lung involvement of childhood-onset rheumatic diseases (RD) patients.

OBJECTIVE: In this investigation, blood levels of 12 cytokines were tested in order to explore their associations with lung involvement in newly diagnosed childhood-onset RD patients.

METHODS: High-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) were performed on 53 newly diagnosed RD patients without any treatment in our department between July 2021 and December 2023. Patients were separated into groups based on whether their lungs were involved or not according to abnormalities found on HRCT or PFTs. We examined the serum cytokines with 41 healthy, age and gender-matched controls.

RESULTS: The majority of serum cytokine levels were statistically different between the RD group with lung involvement and the control group. The RD group with lung involvement had considerably higher serum IL-6 and IFN-γ levels than the RD group without lung involvement or control group. The median serum IL-6 levels were 19 pg/ml [interquartile range (IQR) 6.9, 27.6], 4.4 pg/ml (IQR 2.0, 10.5), and 2.0 pg/ml (IQR 2.0, 2.0) in RD group with lung involvement, RD group without lung involvement, and control group, respectively. Similarly, the median serum IFN-γ levels were 6.0 pg/ml (IQR 5.0, 15), 5.0 pg/ml (IQR 5.0, 5.0), and 5.0 pg/ml (IQR 5.0, 5.0) in RD group with lung involvement, RD group without lung involvement, and control group, respectively. The receiver operating characteristic (ROC) curve study showed that IL-6 and IFN-γ had area under the curve (AUC) values of 0.782 and 0.742, respectively, indicating their significant diagnostic potential for lung involvement in RD patients.

CONCLUSION: Our findings imply that IL-6 and IFN-γ may be associated with the development of lung illnesses and may be involved in the pathophysiology of RD. Thus, in individuals with RD, elevated levels of IFN-γ over 5.42 pg/ml or IL-6 above 6.25 pg/ml may warrant suspicion of lung involvement.

ABSTRACT

BACKGROUND: The aim of this study is to evaluate the changes in the trabecular structure of the mandibular bone and temporomandibular joint following Rapid Maxillary Expansion.

METHODS: Thirty-nine patients who received Rapid Maxillary Expansion treatment in the Department of Orthodontics of the Faculty of Dentistry were selected from the archieve for the study. Trabecular structure changes of the angulus mandible, corpus mandible, and condyle regions were examined using fractal analysis on the dental panoramic radiographs. Radiographs taken before the treatment (T0) and at the end of the 3-month retention period (T1) of the patients.

RESULTS: There was no statistically significant difference between T0 and T1 in the condyle, ramus mandible, and corpus mandible regions depending on time and sex. (p < 0.05) CONCLUSION: The results of this study showed that Rapid Maxillary Expansion treatment does not have a significant impact on the trabecular structure of the mandible and temporomandibular joint depending on time and gender.

ABSTRACT

BACKGROUND: The ZJU index is an innovative computational method which integrates BMI, FBG, TG, and ALT to AST ratio. It strongly correlates with measures of lipid metabolism and glucose intolerance. No researches have yet explored the relationship between the ZJU index and sarcopenia.

METHODS: We analyzed NHANES data from 2011 to 2018, dividing the ZJU index into quartiles. The association was investigated by adjusting for confounders using multivariable linear and logistic regression analysis. Results were visualized through RCS regression and threshold effect analyses. We conducted various subgroup and sensitivity analyses and plotted ROC curves to assess prediction efficacy, with the AUC as the measure of accuracy.

RESULTS: As the ZJU index increases, the prevalence of sarcopenia also rises. Following the control of potential confounders via logistic regression analysis, our research identified a distinct relationship between the ZJU index and sarcopenia, which was statistically significant (P < 0.001), with higher ZJU index values associated with increased risk (OR = 12.40, 95% CI: 8.46-18.17). Interaction analysis suggests that the relationship between the ZJU index and the risk of developing sarcopenia varies significantly between males and females across different ZJU index levels. ROC analysis for the ZJU index shows an AUC of 0.749.

CONCLUSIONS: The ZJU index significantly correlates with a heightened risk of sarcopenia in Americans, suggesting its potential as a predictive marker for sarcopenia.

ABSTRACT

BACKGROUND: Added sugars intake is common among individuals with Parkinson’s disease (PD), yet the link between added sugars intake and PD is not well understood. Our study aims to investigate the association between added sugars intake and PD.

METHODS: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) from1990 to 2020. Added sugars intake was estimated based on a 24-hour dietary recall from participants. Multivariable logistic regression analysis was employed to explore the relationship between added sugars intake and the prevalence of PD. Restricted cubic spline (RCS) was used to explore the nonlinear association between added sugars intake and PD. To further observe whether the conclusions were consistent across different subgroups, we conducted subgroup analyses to investigate the association of added sugars intake with PD in different populations.

RESULTS: The study included 12,489 participants, of which 100 had PD. When weighted, the data represented 136,959,144 participants. The study revealed a positive association between added sugars intake and the prevalence of PD. In multivariable regression models adjusted for all confounding factors, compared with the lowest quartile of added sugars intake, the third quartile (OR = 2.99; 95% CI: 1.43-6.26) and those consuming more than 25% of their calories from added sugars (OR = 3.34; 95% CI: 1.03-10.86) had the highest risk of PD. The RCS curve showed an L-shaped nonlinear association between added sugars intake and PD. Two-segment linear regression by sex revealed that PD prevalence in women was linearly related to sugar intake (nonlinear P = 0.465), while men exhibited an L-shaped nonlinear relationship (nonlinear P = 0.03). Additionally, subgroup analysis showed that alcohol consumption and diabetes significantly influenced the association between added sugars intake and the prevalence of PD.

CONCLUSION: These results highlight a positive association between added sugars intake and the prevalence of PD, particularly among women, heavy drinkers, and individuals with diabetes.

ABSTRACT

BACKGROUND: Prior to the COVID-19 pandemic there were midwifery workforce deficits reported in Australia, but inadequate workforce data to identify retention and attrition in the profession. In the post-pandemic era, workforce deficits continue. This paper reports on midwives’ intentions to leave the profession and explores reasons for and factors associated with having high intention to leave, to inform strategies that can address retention and attrition of midwives.

METHODS: A cross-sectional survey with midwives was conducted in 2017 via an online survey in two maternity care sites in Victoria, Australia. Plans for remaining in or leaving the profession were explored along with reasons for leaving or intending to leave the profession. Other data collected included demographic and workforce characteristics and occupational stressors. Burnout was measured using the Copenhagen Burnout Inventory and job satisfaction using the Midwifery Process Questionnaire. Descriptive statistics, univariate, multivariate analyses, and content analysis were used for data analysis.

RESULTS: Of the 326 respondents (326/508, 64%), over half had considered leaving the midwifery profession in 12 months prior to the study, 20% had thought about leaving frequently and 12% were planning on leaving in the next five years. The main reasons for leaving were not wanting to do shift work, feeling worn out, and experiencing work-related stress. Factors associated with a high intention to leave the profession were work-related burnout, poor job satisfaction and a high intention to leave the workplace. Age did not impact intention to leave but was influential on the reasons for leaving.

CONCLUSIONS: Pre-pandemic, midwives in Victoria, Australia had a high intention to leave the profession regardless of age. Approaches that address midwifery stress, burnout, and fatigue need to be considered, including developing options that offer employment that does not require shift work. To provide safe quality care that supports positive outcomes for women and their families, an appropriate midwifery workforce must be achieved and maintained. Understanding midwives’ intentions to leave the profession is critical and requires ongoing attention given the workforce is likely to remain under significant stress until the major contributing factors are addressed.

ABSTRACT

BACKGROUND: Migrant and ethnic minority populations in Europe are growing, leading to a demand for health systems and health educations to accommodate the growing diversity. Research indicates that health professionals feel inadequately prepared to care for diverse populations, and medical education has gaps in addressing these issues. The aim of the study is to explore whether Danish medical students and newly graduated physicians feel prepared to meet the needs of the increasingly diverse populations.

METHODS: An online survey was emailed to students in the four medical Master’s programs in Denmark and to newly graduated physicians in clinical internships. Data was collected spring 2023. Descriptive statistics reported overall numbers, and multivariate logistic regression was used to model the association between survey answers and the background variables: semester, gender/sex, parent’s education, self-identified ethnicity.

RESULTS: Many medical students and newly graduated physicians feel unprepared to care for patients of backgrounds different from their own. For all items women reported feeling more unprepared than men. Among the medical students and newly graduated physicians with enough clinical experience to answer the question, 34.2% reported feeling helpless at times or often in the past year when treating culturally different patients. Men were less likely than women to report feeling helpless (OR = 0.42; 95% CI 0.28 to 0.64); and self-identified ethnic minorities were 2.59 times more likely than Danish/European medical students and newly graduated physicians to report feeling helpless (95% CI 1.32-5.07).

CONCLUSION: Our findings indicate shortcomings in medical students and newly graduated physicians feeling of preparedness to provide care to patients of backgrounds different from their own. These findings can assist medical education management with identifying curriculum gaps.

ABSTRACT

BACKGROUND: Patient-reported outcome measures (PROMs) provide invaluable information on patients’ health outcomes and can be used to improve patient-related outcomes at the individual, organizational and policy levels. This systematic review aimed to a) identify contemporary applications and synthesize all evidence on the use of PROMs in these contexts and b) to determine characteristics of interventions associated with increased effectiveness.

METHODS: Five databases were searched for studies providing quantitative evidence of the impact of PROM interventions. Any study design was permitted. An overall benefit (worsening) in outcome was defined as a statistically significant improvement (deterioration) in either a PROM, patient-reported experience measure or clinical outcome. Study quality was assessed using the Effective Public Healthcare Panacea Project’s Quality Assessment Tool for Quantitative Studies. A narrative synthesis was conducted.

RESULTS: Seventy-six studies of the 11,121 articles identified met the inclusion criteria. At the individual level, 10 (43%) of 23 studies that fed back PROMs to the patient or healthcare provider showed an improvement in outcome. This percentage increased in studies which used PROMs to monitor disease symptoms and linked these to care-pathways: 17 (68%) of 25 studies using this mechanism showed an improvement. Ten (71%) of 14 studies using PROMs to screen for disease found a benefit. The monitoring and screening approach was most effective using PROMs covering cancer-related, depression and gastro-intestinal symptoms. Three studies found that the mere collection of PROMs resulted in improved outcomes. Another three studies used PROMs in decision aids and found improved decision quality. At the organizational/policy level, none of the 4 studies that used PROMs for benchmarking found a benefit. The three studies that used PROMs for in-depth performance analyses and 1 study in a plan-do-study-act (PDCA) cycle found an improvement in outcome. Studies employing disease-specific PROMs tended to observe improved outcomes more often. There are concerns regarding the validity of findings, as studies varied from weak to moderate quality.

CONCLUSIONS: The use of PROMs at the individual level has matured considerably. Monitoring/screening applications seem promising particularly for diseases for which treatment algorithms rely on the experienced symptom burden by patients. Organizational/policy-level application is in its infancy, and performance evaluation via in-depth analyses and PDCA-cycles may be useful. The findings of this review may aid stakeholders in the development and implementation of PROM-interventions which truly impact patient outcomes.

ABSTRACT

BACKGROUND: To assess the psychosocial impact of moderate-severe juvenile idiopathic arthritis (JIA) on patients and their families, among those who had been treated with at least one anti-tumor necrosis factor (anti-TNF-α), according to routine clinical practice in Spain.

PATIENTS AND METHODS: A 24-month observational, multicentric, cross-sectional and retrospective study was performed. Children diagnosed with JIA were enrolled at three tertiary-care Spanish hospitals. The study included children treated with biologic disease-modifying antirheumatic drugs (bDMARD) who participated in a previous study, the ITACA, and who continued follow-up in these pediatric rheumatology units. Patient health-related quality of life (HRQoL) was assessed using the Pediatric Quality of Life Inventory (PedsQL™). Caregivers completed an interview to gather information about school attendance, their children’s participation in school and social activities, its impact on their jobs and social life and perceived psychosocial support. A descriptive statistical analysis of all the variables was performed. The Mann-Whitney-U test or Kruskall-Wallis H test were used to compare quantitative variables and Fisher’s exact tests was used for qualitative variables. Tests were two-tailed with a significance level of 5%. The data were analyzed using SPSS V18.0 statistical software.

RESULTS: One hundred and seven patients were included. Overall, patients were on inactive disease or low disease activity according to JADAS-71 score and had very low functional disability according to CHAQ score. Up to 94.4% of patients were receiving drug treatment, mainly with bDMARD in monotherapy (84.5%). Based on PedsQL, patients and parents referred a high HRQoL. School Functioning PedsQL domain achieved the lowest score. Work and social impact due to the child´s disease was greater for mothers than for fathers. The understanding of the disease was lower at school than in the with family and friends’ environments.

CONCLUSION: Most of the patients had a high HRQoL and had controlled disease activity, despite having a negative psychosocial impact on some of them and their families, mainly on school functioning. Children’s disease seems to involve greater work and psychosocial impacts for mothers than for fathers of children affected by JIA.
