ABSTRACT

Autism Spectrum Disorder (ASD) is defined as a neurodevelopmental condition distinguished by unconventional neural activities. Early intervention is key to managing the progress of ASD, and current research primarily focuses on the use of structural magnetic resonance imaging (sMRI) or resting-state functional magnetic resonance imaging (rs-fMRI) for diagnosis. Moreover, the use of autoencoders for disease classification has not been sufficiently explored. In this study, we introduce a new framework based on autoencoder, the Deep Canonical Correlation Fusion algorithm based on Denoising Autoencoder (DCCF-DAE), which proves to be effective in handling high-dimensional data. This framework involves efficient feature extraction from different types of data with an advanced autoencoder, followed by the fusion of these features through the DCCF model. Then we utilize the fused features for disease classification. DCCF integrates functional and structural data to help accurately diagnose ASD and identify critical Regions of Interest (ROIs) in disease mechanisms. We compare the proposed framework with other methods by the Autism Brain Imaging Data Exchange (ABIDE) database and the results demonstrate its outstanding performance in ASD diagnosis. The superiority of DCCF-DAE highlights its potential as a crucial tool for early ASD diagnosis and monitoring.

ABSTRACT

Preoperative management of patients living with severe obesity can be challenging; in this context, the preoperative weight loss may help to obtain better outcomes and less morbidity for bariatric surgery. Therefore, we evaluated the effectiveness of GLP-1 analogue Liraglutide in preoperative weight loss. We performed a single-center, quasi-experimental prospective study. Eligible participants were adults in preoperative management for bariatric-metabolic surgery with body-mass index ≥ 48 kg/m². All patients were assigned liraglutide treatment, with an initial dose of 0.6 mg subcutaneous per day, the dose was increased each week until reaching 3.0 mg for 12 weeks. Weight loss and body composition were evaluated monthly using bioelectric impedance (BIA) (InBody 770 Scale®). We analyzed data using descriptive statistics, central tendency measures and dispersion for quantitative variables and absolute and relative frequencies for qualitative variables. A total of 37 individuals were included in this study, 28 (76%) were female and 9 (24%) were males, with an average age of 44 years. About the BMI, 19 patients (51%) had a BMI > 50 kg/m², 10 (27%) > 40 kg/m² and 8 (22%) > 60 kg/m²; with a total average BMI of 56.04 kg/m². The initial weight was 147.4 ± 14.9 kg which decreased to 139.3 ± 16.8 kg; after 3 months of liraglutide administration. A total of 35 patients had some degree of weight loss (94.6%), while 2 (5.40%) had no weight changes. The total weight loss was 5.50% at 3 months of liraglutide treatment. Liraglutide could be an effective adjuvant therapy for preoperative weight loss in patients living with severe obesity.

ABSTRACT

RATIONALE: Accurate identification of old rice samples from new ones benefits their market circulation and consumers. However, the current detection methods are still not satisfactory because of their insufficient accuracy or (and) time-consuming process.

METHODS: Chelating carboxylic acids (CCAs) were selectively extracted from rice, by stirring with chelating resin and a dilute Na₂CO₃ solution. The green analytical chemistry guidelines for sample preparation were investigated by using the green chemistry calculator AGREE prep. The extractant was determined by liquid chromatography-mass spectrometry (LC/MS), and statistical analysis of the analytical data was carried out to evaluate the significance of the difference by ChiPlot.

RESULTS: The limit of quantitation for the CCAs is in the range of 1 to 50 ng/mL, with a reasonable reproducibility. The CCAs in 23 rice samples were determined within a wide concentration range from 0.03 to 1174 μg/g. Intriguingly, the content of citric acid, malonic acid, α-ketoglutaric acid and cis-aconite acid in new rice was each found to be distinctively higher than that in old rice by several times. Even mixtures of old and new rice were found to show much difference in the concentration of citric acid and malic acid.

CONCLUSION: A green analytical method has been developed for the simultaneous determination of CCAs by LC/MS analysis, and the identification of old rice samples from new ones was easily carried out according to their CCA content for the first time. The results indicated that the described method has powerful potential for the accurate identification of old rice samples from new ones.

ABSTRACT

OBJECTIVE: This systematic review aims to summarize the current body of evidence concerning the prevalence of obesity among clergy (i.e., the officially designated leaders of a religious group) in the United States.

METHOD: From November 2022 to February 2023, five databases, one data repository, and gray matter were searched for articles and data sources. The search was restricted to articles published or raw data collected from 2001 to 2021. Study quality was assessed with a template, and heterogeneity was assessed using the I 2 $$ {I}^2 $$ statistic. The protocol for this review was registered with PROSPERO (CRD42022376592).

RESULTS: Forty-seven studies of clergy obesity involving 35,064 individuals were eligible. The pooled prevalence estimate of obesity across studies was 34.8% (95% confidence interval [CI]: 32.5-37.2). Obesity prevalence was found to be increasing over time and to vary considerably between clergy from different religious traditions. Compared to national estimates, from 2005 onwards, obesity prevalence was higher than in the US adult population.

ABSTRACT

Preoperative depression is prevalent among patients undergoing metabolic and bariatric surgery (MBS) and is a potentially modifiable risk factor. However, the impact of preoperative depression on MBS outcomes has not been systematically reviewed. A search of MEDLINE, Embase, Cochrane, and PsychINFO (inception to June 2023) was conducted for studies reporting associations between preoperative depression and any clinical or patient-reported outcomes after MBS. Eighteen studies (5 prospective and 13 retrospective) reporting on 5933 participants were included. Most participants underwent gastric bypass or sleeve gastrectomy. Meta-analyses were not conducted due to heterogeneity in reported outcomes; findings were instead synthesized using a narrative and tabular approach. Across 13 studies (n = 3390) the associations between preoperative depression and weight loss outcomes at 6-72 months were mixed overall. This may be related to differences in cohort characteristics, outcome definitions, and instruments used to measure depression. A small number of studies reported that preoperative depression was associated with lower quality of life, worse acute pain, and more perioperative complications after surgery. Most of the included studies were deemed to be at high risk of bias, resulting in low or very low certainty of evidence according to the Risk of Bias In Non-randomized Studies – of Exposure (ROBINS-E) tool. While the impact of preoperative depression on weight loss after MBS remains unclear, there is early evidence that depression has negative consequences on other patient-important outcomes. Adequately powered studies using more sophisticated statistical methods are needed to accurately estimate these associations.

ABSTRACT

Toxicology studies in early fish life stages serve an important function in measuring the impact of potentially harmful substances, such as crude oil, on marine life. Morphometric analysis of larvae can reveal the effects of such substances in retarding growth and development. These studies are labour intensive and time consuming, typically resulting in only a small number of samples being considered.An automated system for imaging and measurement of experimental animals, using flow-through imaging and an artificial neural network to allow faster sampling of more individuals, has been described previously and used in toxicity experiments. This study compares the performance of the automated imaging and analysis system with traditional microscopy techniques in measuring biologically relevant endpoints using two oil treatments as positive controls.We demonstrate that while the automated system typically underestimates morphometric measurements relative to analysis of manual microscopy images, it shows similar statistical results to the manual method when comparing treatments across most endpoints. It allows for many more individual specimens to be sampled in a shorter time period, reducing labour requirements and improving statistical power in such studies, and is non-invasive allowing for repeated sampling of the same population.

ABSTRACT

PURPOSE/OBJECTIVES: Treating intraosseous lesions (IOLs) and interradicular bone lesions (IRLs) is an extremely technical dental procedure in periodontics. Instrumentation of these lesions is often perceived as difficult by students and inexperienced dentists before they perform a certain number of procedures on patients in the clinic. The aim of this article is to evaluate a cost-effective three-dimensional (3D)-printed educational simulator for the periodontal treatment of IOLs/IRLs (including scaling, incisions and sutures).

METHODS: The simulators were first developed digitally, and then manufactured using printable resins and specific materials; finally, they were assembled using different bonding systems. To evaluate the simulators, assessments were gathered from two target populations: undergraduate students and periodontics experts. These individuals tested the simulator and completed a cross-sectional questionnaire based on a Likert scale with comparative and pedagogical items scored from one to five. The purpose of the questionnaire was to compare our simulator to clinical reality (i.e., operation on human jaws) and to an animal simulator (i.e., simulation of porcine jaws). The results are expressed as the mean and standard deviation and were statistically analyzed with the Wilcoxon signed-rank test.

RESULTS: Overall, the results were satisfactory for both groups of testers (4.70 and 4.61 out of five for students and experts, respectively, for global satisfaction).

CONCLUSIONS: The overall educational relevance of the simulator designed herein highlights the fact that 3D-printed educational simulators could enable efficient cognitive-functional learning for clinical IOL/IRL treatment.

ABSTRACT

OBJECTIVE: To investigate whether compression therapy after thermal ablation of varicose veins can improve the prognosis of patients.

METHODS: Systematic research were applied for Chinese and English electronic databases(PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, VIP Databases). Eligible prospective studies that comparing the efficacy of compression therapy and non-compression therapy on patients after thermal ablation of varicose veins were included. The interest outcome such as pain, quality of life (QOL), venous clinical severity score (VCSS), time to return to work and complications were analyzed.

RESULTS: 10 studies were of high quality, and randomized controlled trials involving 1,545 patients met the inclusion criteria for this study. At the same time, the meta-analysis showed that the application of compression therapy improved pain (SMD: -0.51, 95% CI: -0.95, -0.07) but exhibited no statistically significant effect on QOL (SMD: 0.04, 95% CI: -0.08, 0.16), VCSS (MD: -0.05, 95% CI: -1.19, 1.09), time to return to work (MD: -0.43, 95% CI: -0.90, 0.03), total complications (RR: 0.54, 95% CI: 0.27, 1.09), and thrombosis (RR: 0.71, 95% CI: 0.31, 1.62).

CONCLUSION: Compression therapy after thermal ablation of varicose veins can slightly relieve pain, but it has not been found to be associated with improvement in other outcomes.

ABSTRACT

OBJECTIVE: To determine if electronic medical record (EMR) changes and implementation of a study on firearm storage practices changed identification of firearm exposure in children presenting to a pediatric emergency department (PED) with mental health complaints. We also sought to determine the accuracy of information collected on firearm storage practices.

METHODS: Retrospective study of EMR documentation of firearm exposure in PED patients with mental health complaints from January 20, 2015 until November 20, 2017. EMR changes occurred on January 20, 2016 and the firearms study began on February 13, 2016. The primary outcome was documentation of firearm exposure. Secondary outcomes were documentation of unsafe firearm storage practices. We also examined differences between clinical and research documentation of unsafe firearm storage practices post-intervention. We compared groups using descriptive statistics and chi-squared tests. We used statistical process control to examine the relationship between interventions and changes in outcomes.

RESULTS: 5582 encounters were examined. Identification of firearm exposure increased from 11 to 17% postintervention. Identification of unsafe storage practices increased from 1.9% to 4.4% across all encounters. Special cause variation in both metrics occurred concurrently with the interventions. Postintervention, unsafe firearms storage practices in firearm owning families were under-identified (39% identified as not triple-safe in clinical data vs 75% in research data).

CONCLUSIONS: EMR changes and implementation of a firearms study improved identification of firearm exposure and unsafe storage practices in families of PED patients being evaluated for mental health complaints. However, unsafe storage practices continued to be under-identified in firearm-owning families.

ABSTRACT

BACKGROUND: The COVID-19 disease has a negative impact on the psychophysiological health of populations worldwide, including a decrease in overall physical performance and an increase in fatigue. Fatigue was one of the main symptoms reported by patients and persisted for several weeks after infection with COVID-19. Although the phenomenon of fatigue is still poorly understood, physical activity can be a supportive factor in combating feelings of fatigue and lack of energy. The purpose of this research was to assess the physical activity (PA) and fatigue levels of teachers in Poland and the United Kingdom in the first year after the COVID-19 pandemic.

MATERIAL AND METHODS: The online research was carried out among 410 teachers from Poland and the United Kingdom. The PA level was assessed using the International Physical Activity Questionnaire (IPAQ). The level of fatigue was measured using the Modified Fatigue Impact Scale (MFIS).

RESULTS: Polish teachers, regardless of sex, are more physically active (the differences relate mainly to walking and moderate activity). When assessing the level of fatigue, there is a significant difference between men and women – the former indicate a higher degree of fatigue, with the difference between the sexes being particularly large in the Polish community. Quite clearly, there is an association between less activity (except walking) and more fatigue. All models show a statistically significant effect of total fatigue on total effort. Physical activity is not very strongly correlated with age but the level of fatigue increases with age.

CONCLUSIONS: The problem of teacher fatigue is unfortunately widespread. They should be encouraged to engage in as much PA as possible during the day. When planning and targeting fatigue reduction campaigns, PA should be encouraged and variables such as age, sex should be taken into account.
