Association of Diabetes Mellitus with Carotid Artery Stenosis Undergoing Coronary Artery Bypass Graft in Bangladesh: A Prospective Cross-Sectional Study.

Atherosclerosis is a systemic vascular disease commonly affecting coronary and carotid arteries, particularly in diabetes mellitus (DM). This study assessed the association of DM with significant carotid artery stenosis (CAS) among the coronary artery disease (CAD) population undergoing isolated elective coronary artery bypass graft (CABG) surgery. A prospective cross-sectional study evaluated 100 Bangladeshi CAD patients who underwent isolated elective CABG from January 2017 to September 2019. Initially, a univariate analysis curtails the risk patterns, followed by a Pearson correlation analysis of significant CAS and glycated haemoglobin (HbA1c). Although the majority of patients were male, females were higher in the diabetic than non-diabetic group (38.1% vs 15.5%; p=0.01). Overall, ~38% of diabetic patients had significantly higher ≥50% CAS. Further, 28.6% and 9.5% of the diabetic sample had 50-70% and >70% CAS, respectively, which is significantly (p =0.02) higher than the non-diabetic sample (8.6% and 1.7%, respectively). Additionally, diabetes was significantly more associated with both unilateral (31.0% vs 22.4%) and bilateral (45.2% vs 22.4%) CAS than the non-diabetic population (p=0.006). The Pearson correlation coefficient shows a significant positive association between higher glycated haemoglobin levels and >50% CAS (correlation coefficient 0.270; p = 0.007). We found higher HbA1c had a significant positive correlation with >50% CAS in diabetic patients undergoing elective CABG, recommending preoperative carotid screening, especially elderly individuals.

A Cephalometric Evaluation of Anterior Cranial Base Slope in Patients with Different Skeletal Malocclusions

Objective: To assess the correlation in the anterior cranial base (SNA, SNB angles) and among the three different skeletal malocclusions. Study Design: Descriptive cross-sectional study. Study setting: Orthodontic Department KRL Hospital G-9, Islamabad, from March to August 2024. Methodology: The data included lateral cephalograms of people undergoing orthodontic treatment. By simple consecutive non-random sampling technique, a total sample size of 120 patients was selected. IBM SPSS version 23.0 was used for the data analysis. Quantitative data like age, SNA, SNB and ACB slope was expressed in mean (SD) as descriptive statistics. Pearson correlation coefficient was used to evaluate the relationship between the anterior cranial base and the skeletal malocclusions. A p-value ≤ 0.05 was considered statistically significant. Results: Out of 120 patients evaluated in this study, the distribution across the three skeletal malocclusions was as follows: 10% were classified as skeletal class I, 65% as skeletal class II, and 25% as skeletal class III. A significant correlation was observed between the anterior cranial base slope and the type of skeletal malocclusion (p < 0.05). The patients with Class II malocclusion, the SNA angle was notably higher while in Class III malocclusion patients, the SNB angle was significantly increased. Additionally, the SN-FH angle demonstrated a steeper slope in Class III patients compared to those with Class I and Class II malocclusions. There was no significant difference in anterior cranial base length (BA-S) across the malocclusion groups. The correlation analysis between SNA, SNB, and the anterior cranial base slope indicated that the steepness of the cranial base plays a role in the manifestation of the skeletal malocclusions. Conclusion: This research study underscores the significance of the anterior cranial base in the development of skeletal malocclusions. The findings suggest that patients with Class II malocclusion exhibit a steeper anterior cranial base slope, whereas Class III patients tend to have a flatter cranial base slope. These variations in anterior cranial base morphology can serve as effective diagnostic tools in the assessment, evaluation, and treatment planning of skeletal malocclusions. The study also highlights the complex interplay between cranial base morphology and skeletal relationships, indicating the need for comprehensive analysis in orthodontic assessment and treatment strategies.

The influence of regional online media on public opinion formation under martial law in Ukraine

Introduction: The paper's objective is to study the influence of regional online media on public opinion formation under martial law in Ukraine. Methods: Methods such as a questionnaire-based survey, online media monitoring, and content analysis were used in the study. Statistical methods of data analysis included the Pearson correlation coefficient. Reliability coefficient Cronbach's alpha enabled verification of tools and methods' reliability.Results: The study revealed that regional online media hold a certain level of trust, with 40% of respondents relying on the information they provide. However, 20% believe the topics do not meet their interests, 30% criticize the lack of unique content, and 40% think the media do not influence their views. Regional media demonstrate the ability to impact social processes: 50% of respondents noted an influence on public opinion, 45% on government perception, 60% on information security, and 70% on language policy. An analysis of war coverage shows that nationwide outlets like Ukrainska Pravda, BBC Ukraine, and Radio Svoboda focus on military actions, humanitarian issues, and political contexts. The correlation coefficient between nationwide and regional media ranges from 0.45 to 0.93, indicating a moderate positive correlation and differences in their war coverage approaches.Conclusions: The study demonstrated the significant influence of regional online media on public opinion formation, but under conditions of war, this role does not prevail over the role of central mass media. Further research should concentrate on studying the factors promoting the efficiency of information delivery by online media.

Use of small unmanned aircraft systems in airfield pavement inspection: implementation and potential

ABSTRACT Routine maintenance can make an airfield pavement last for an extended period and regular pavement inspections help to identify the need for such maintenance. There is scope for comprehensively evaluating small Unmanned/Uncrewed Aircraft Systems (sUAS), also known as drone, data use in airfield pavement inspection. This research team collected sUAS data from six airports, which were processed into red-green–blue (RGB) orthophotos, Digital Elevation Models (DEMs), hillshades from DEMs, and thermal orthophotos. The RGB optical data were useful in detecting 13 out of 14 available Portland cement concrete (PCC) pavement distresses and 5 out of 9 available asphalt concrete (AC) pavement distresses. DEMs were also useful in confirming the location of distresses with elevation changes. RGB data of 1.5 mm/pixel and DEM data of 6 mm/pixel or better were recommended for pavement distress detection and rating. Pavement Condition Index (PCI) values were calculated using sUAS data and compared with foot-on-ground (FOG) inspection PCI values. The mean differences between FOG PCI and sUAS PCI ranged from 1.3 to 9.1 for six airports. The Pearson correlation coefficient R-value varied from 0.79 to 0.90, showing a strong correlation and demonstrating the potential for future integration of sUAS-based PCI inspection to complement FOG inspection.

It was observed that 33% of the students frequently use e-learning and b-learning platforms. Conclusions: The four English language skills analyzed show significant learning outcomes thanks to the use of virtual platforms.

Relationship between Cancer Incidence and Health Behaviors from Ecological Study in Korea.

The aim of this ecological study was to examine the correlation between cancer incidence and health behaviors such as smoking, alcohol consumption, and obesity, and investigated whether there were differences in this correlation between metropolitan areas and other regions. Data on health behaviors exposure/prevalence and cancer incidence rates for 227 administrative districts (cities and counties) were obtained. The average exposure proportion measured annually from 2008 to 2011 in the Korea Community Health Survey data and the age-standardized cancer incidence data from 2014 to 2018, obtained through the cancer registry data, were downloaded from the Statistics Korea website. To examine the relationship between smoking, alcohol consumption, obesity exposure rate (prevalence), and cancer incidence, a correlation analysis was conducted, and Pearson's correlation coefficient was calculated. The correlation coefficient between male smoking and male cancer incidence rate across 227 districts was 0.259. This significance was more pronounced in large metropolitan areas, where the correlation coefficient was 0.631 in the 73 districts belonging to these areas. In large metropolitan areas, the correlation coefficient between alcohol consumption rate and cancer incidence rate was 0.390. In the correlation analysis between obesity prevalence and cancer incidence rate, no correlation was found in large metropolitan areas, while in areas outside of large cities, the correlation coefficient was -0.295, indicating a significant negative correlation. This ecological study demonstrated that the relationship between cancer incidence and health behaviors differed between large metropolitan areas and areas outside of large cities.

Correlation between the upper airway volume and Ricketts’ facial biotypes: a cone-beam computed tomography study

Objectives: This study aimed to determine if there are differences in the upper airway space between the three facial biotypes described by Ricketts. It also investigated if there are anatomical differences between males and females at the upper airway level. Methods: Data was collected from a private orthodontic clinic. Orthodontic tracing was done using NemoFab Ortho software to obtain the dentoskeletal measurements: anterior facial height, posterior facial height, maxillary width, and palatal depth. The upper airway measurements were achieved using the same software by identifying landmarks for each upper airway compartment (nasopharynx and oropharynx). The Pearson correlation coefficient was used to determine the correlation between the variables α=0.05). Results: The sample included eighty patients with a mean age of 30.4 years, predominantly females (67.5%). Statistical differences were found between brachyfacial and dolichofacial patients regarding the oropharynx volume (p=0.009) and total volume (p=0.027). Regarding the comparison by sex, male patients had significantly higher mean values for upper airway volumes and all the dentoskeletal features analyzed, except for maxillary width. Conclusions: There are statistical differences in the upper airway space among different facial biotypes. Brachyfacial patients seem to have higher upper airway volumes than Dolichofacial patients. Moreover, males showed higher upper airway volumes than females.

Machine Learning Quantification of Fluid Volume in Eyes With Retinal Vein Occlusion Treated With Aflibercept: The REVOLT Study.

Purpose: To evaluate the combined relationship between ischemia, retinal fluid, and layer thickness measurements with visual acuity (VA) outcomes in patients with retinal vein occlusion (RVO). Methods: Swept-source optical coherence tomography (OCT) data were used to assess retinal layer thickness and quantify intraretinal fluid (IRF) and subretinal fluid (SRF) using a deep learning-based, macular fluid segmentation algorithm for treatment-naïve eyes diagnosed with visual impairment resulting from central RVO (CRVO) or branch RVO (BRVO). Patients received 3 loading doses of 2 mg intravitreal aflibercept injections and were then put on a treat-and-extend regimen. Image analysis was performed at baseline and postoperatively at 3 months and 6 months. The baseline OCT morphologic features and fluid measurements were correlated with the changes in best-corrected VA (BCVA) using the Pearson correlation coefficient (r). Results: The study comprised 49 eyes. A combined model incorporating thickness in the outer plexiform layer (OPL), retinal nerve fiber layer (RNFL), and presence of IRF had the strongest overall correlation for CRVO (r = 0.865; P < .05). For BRVO, the addition of IRF to the OPL-inner nasal model had a strong correlation (r = 0.803; P < .05). The baseline ischemic index in the deep capillary complex showed a notable correlation with the 6-month change in BCVA for CRVO (r = 0.9101; P < .001) and BRVO (r = 0.9200; P < .001). Conclusions: A combined model of IRF volume, OPL, and RNFL layer thicknesses, along with ischemic indices, provides the best correlation to BCVA changes. Combined fluid and layer segmentation of OCT images provides clinically useful biomarkers for RVO patients. These results give insight into the pathology of RVOs and describe the relationship between deep capillary complex ischemia and OPL/RNFL thickness in BCVA outcomes.

Diagnoses of postpartum urinary retention using next-generation non-piezo ultrasound technology: assessing the accuracy and benefits

Postpartum urinary retention has a wide range of publicized incidences, likely caused by frequent misdiagnosis of this puerperal complication. Especially covert postpartum urinary retention has a high number of missed diagnoses due to the lack of symptoms and the time-extensive diagnostics via ultrasound, leading to no treatment and no appropriate follow-up. To simplify the diagnosis and establish a screening tool we analyzed the application of portable handheld-ultrasound devices (PUD) as used in Point-of-care diagnostics in comparison to established standard ultrasound devices (SUD). This prospective study aimed to evaluate the reliability of non-piezo, chip-based PUD in comparison to the measurement withSUD, containing a piezo transducer, as golden standard for the ultrasound diagnosis of postpartum urinary retention. Randomly, 100 participants between the first and seventh day after delivery in an obstetric ward underwent ultrasound examinations using a EPIQ 5 W (Philips) as SUD and a Butterfly iQ (Butterfly Network) as PUD to compare the accuracy in bladder size after micturition and the estimated post-void residual volume. Intraclass correlation coefficients, Bland-Altman plots, and Pearson correlation coefficients were used for analyzing the reliability and agreement between the measurements of these devices and were calculated for subgroups as body mass index, mode of delivery and timepoint of delivery. The results show a near-perfect agreement (0.994) and correlation (r = 0.982) for estimated post-void residual volume and for most measurements between the two types of ultrasound devices. The agreement rate for the diagnosis of covert postpartum urinary retention is 100%. Subgroup analyses lack a significant difference reflected by agreement and correlation rates. These findings affirm the high reliability of PUD for the diagnosis of postpartum urinary retention and supports their integration into daily clinical practice, thereby simplifying regular controls of the bladder by physicians during daily rounds on the ward. This technology may allow a higher diagnosis rate so that patient care can be optimized and the long-term impact on continence and quality of life can be studied and analysed.

Turkish adaptation of the behavioral flexibility scale for children with autism spectrum disorder: cross-cultural adaptation and psychometric evaluation

PurposeThe purpose of this study is to adapt the “Behavioral Flexibility Scale for Children with Autism Spectrum Disorder” to Turkish culture and evaluate its psychometric properties.Design/methodology/approachThe Behavioral Inflexibility Scale (BIS), developed by Luc Lecavalier and her colleagues, is used in diagnostic tests for autistic children. The research used a methodological design. Data were collected between March and September 2021. The study included 254 parents of children with autism. Content validity, construct validity and criterion validity were assessed. Reliability was examined using adjusted item-total correlation, Cronbach’s coefficient, composite reliability and split-second reliability.FindingsThe Turkish version of the “Behavioral Flexibility Scale for Children with Autism Spectrum Disorder” was found to have good content and criterion validity. The single-factor structure of the scale was confirmed for the Turkish version as a result of confirmatory factor analysis. The Cronbach alpha coefficient of the scale was determined as 0.97, and the item/total correlation coefficients were found to be between 0.544 and 0.807. In the first factor analysis conducted for BIS, the KMO value was 0.958, and in the BTS test results, it was determined that the scales were suitable for factor analysis (X2 = 7,296.05; df = 705; p < 0.001). As a result of the explanatory factor analysis, it was found that the items forming the scale were gathered under a single factor, and the factor loadings varied between 0.564 and 0.822. It was found that the items constituting the scale explained 52% of the variance, and the Pearson correlation coefficient was r = 0.775, p < 0.001.Research limitations/implicationsIn this study, there are some limitations that need to be acknowledged. First, the sample that the study is based on was collected from parents from a single city in our country, and therefore, in future studies, it is recommended to use a stratified sampling method to include participants from all regions of the country. Another limitation is that the behavioral flexibility of children and adolescents with autism spectrum disorder (ASD) was assessed only based on the information provided by their parents. This leads to a one-sided evaluation of the results. Therefore, in future studies, it is recommended to include various sources such as special education teachers and attending physicians to assess the behavioral flexibility of children and adolescents with ASD.Practical implicationsThe Behavioral Flexibility Scale was found to be a valid and reliable tool that can be used in diagnostic testing in children with ASD.Social implicationsIt is aimed to early identify and intervene in the behavioral problems experienced by autistic children.Originality/valueThe Behavioral Flexibility Scale was found to be a valid and reliable tool that can be used in diagnostic testing in children with ASD.

An original feature retention deconvolution algorithm and its application to bearing fault diagnosis

Abstract Traditional blind deconvolution algorithms perform well in estimating the repetition rate of impulses within signals; however, they fall short in preserving the original features of the signal. In engineering applications, particularly for cyclic impulse signals, maintaining signal fidelity is as crucial as accurately estimating impulse counts, making pure impulse count estimation insufficient for practical needs. To address this limitation, we propose a novel deconvolution algorithm—maximum correlation Pearson fidelity coefficient deconvolution (MCPSFD). This method constructs an objective function based on two key metrics: the correlation Pearson coefficient (CPC), which quantifies the periodicity of impulses, and the signal fidelity coefficient (SFC), which measures the similarity between the original and recovered signals. By combining CPC and SFC, we introduce a new objective function, termed the correlated Pearson fidelity factor (CPSF), which simultaneously considers both the number of impulses and the original characteristics of the filtered signal without introducing redundant parameters. The MCPSFD algorithm is derived by maximizing the CPSF function. Extensive experiments on simulated and measured bearing signals demonstrate that the proposed method significantly outperforms existing deconvolution algorithms in recovering periodic impulses and minimizing signal distortion.
