Kendall's Tau Research Articles

Experienced veterinary surgeons require multiple attempts but gain proficiency rapidly in robotic simulator tasks.

To assess attempts to proficiency of experienced veterinary surgeons for 2 surgical tasks when using a robotic simulator (Mimic dV-Trainer; Surgical Sciences) and determine factors associated with the successful performance of these tasks. Veterinary surgeons with rigid, minimally invasive surgery experience performed 2 tasks ("pick and place" and "knot the ring 1") using the simulator until they attained proficiency. Individual performance variables were recorded. The number of attempts to proficiency was recorded. Performance variables were also assessed for effect on proficiency by the Kendall tau correlation and hierarchical multiple linear regression. The study period was from July 25, 2022, through December 14, 2022. The 18 surgeons enrolled required a median of 8.5 attempts (95% CI, 7 to 12; range, 6 to 22) to reach proficiency for the basic task versus 27 attempts (95% CI, 21 to 38; range, 10 to 63) for the advanced task. Surgeons took a median of 6 minutes (range, 3 to 11 minutes) to complete training for the basic task and 12 minutes (range, 4 to 46 minutes) for the advanced task. The number of attempts to reach proficiency correlated strongly with economy of motion (tau = 0.72), instrument collisions (tau = 0.72), and time to completion (tau = 0.96). Although experienced surgeons required a high number of attempts to gain proficiency in robotic simulator tasks, they did achieve proficiency quickly, encouraging future investigations into their use for training. Specific motion metrics were identified which improved efficiency during training.

Rooftop solar potential in micro, small, and medium size enterprises: An insight into renewable energy tapping by decision-making approach

Rooftop solar micro-power plants mitigate pollution and transmission problems in crowded Indian cities. The Indian government is exploring alternate solutions, and the micro, small, and medium enterprises (MSME) sector is also coming forward to opt for sustainable solutions. This study is focused on the MSME segment in India, which constitutes approximately 63 million entities. Installing a solar system for which a rooftop could be the best place to tap solar energy from these entities is required. Checking the rooftop solar potential of any MSME entity requires a suitable technique to decide which sector to target first and the further order. A unique methodology based on multi-criteria decision-making (MCDM) methods is presented to rank 10 MSME alternatives with seven criteria. It includes the measurement of alternatives and ranking according to compromise solution (MARCOS) to rank MSME sectors in India with rooftop solar potential. Weights of importance are assigned with three objective techniques and combined with the Bonferroni operator. The ranks attained are compared with different MCDM methods, and sensitivity analysis is performed while changing weights. Kendall and Spearman rank correlation coefficients are utilized to access the correlation levels between various strategies. Finally, Garrett’s ranking technique is used to finalize the different ranks. The results reveal that the MARCOS method performed well, and “textiles” ranks first, followed by “auto and engineering products.” As a result, the leading industrial sectors will help improve energy utilization while concentrating on renewable energy resources.

Childhood Parental Neglect, Abuse and Rejection Among Transgender Women: A Cross-Sectional Study in Rio de Janeiro, Brazil.

We aimed to estimate the proportions of childhood parental neglect, abuse, and rejection and to evaluate the co-occurrence of these experiences among transgender women in Rio de Janeiro, Brazil. This was a cross-sectional study with a convenience sample enrolled between July 2019 and March 2020, using an adapted version of the Childhood Trauma Questionnaire. Proportions and corresponding confidence intervals (CI) were calculated. Kendall correlation with Tau-b estimator was used in the bivariate analyses. We gathered data from 139 participants. The most prevalent types of childhood traumas were emotional abuse (60.43%, 95% CI [51.79, 68.62]), physical abuse (57.55%, 95% CI [48.90, 65.89]) and sexual abuse (44.60%, 95% CI [36.18, 53.27]). Severe to extreme physical and emotional abuse occurred among 40.29% (95% CI [32.06, 48.93]) and 5.75% (95% CI [2.51, 11.02]) of participants, respectively. The proportion of parental rejection (eviction) was 32.37% (95% CI [25.04, 40.69]) and occurred with the other forms of abuse, except sexual abuse. Multiple types of childhood abuse, neglect, and parental rejection were observed among transgender women in our sample. The harmful effects of childhood abuse on the mental and physical health of people in the transgender population are of concern, particularly considering the cumulative effect produced by the co-occurrence of such events and their harmful lifetime effects. It is urgently necessary to debate and formulate public policies to ensure the right to gender expression from childhood.

THE CORRELATION BETWEEN KNOWLEDGE AND BEHAVIOR OF VULVA HYGIENE WITH PATHOLOGICAL LEUKORRHEA INCIDENCE

Vulva hygiene is important to prevent pathological vaginal discharge. Adolescent girls are susceptible to such discharge due to insufficient awareness of proper hygiene practices. A preliminary study identified instances of improper wiping techniques and failure to adequately dry the vulva before donning underwear among students. Moreover, some students reported experiencing genital itching. The purpose of this study was to determine the correlation between knowledge and behavior of vulva hygiene with pathological vaginal discharge This study employed a correlational cross-sectional design. The population consisted of 52 female students at Al-Hasani Islamic Boarding School, selected through total sampling. Data were collected using validated and reliable questionnaires. Statistical analysis utilized Kendall's Tau correlation test. This research has passed an ethical review with letter number 1450/UN22.9/PG/2024 which considers research ethics in the form of informed consent, anonymity, privacy, confidentiality, justice, and beneficience. The results are 65.4% of respondents had good knowledge of vulva hygiene, 53.8% exhibited good vulva hygiene behavior, and 50% experienced pathological leucorrhea. Correlation analysis revealed no significant correlation between knowledge (ρ value = 0.087) or behavior (ρ value = 0.582) of vulva hygiene and pathological leucorrhea incidence. Further research is needed regarding factors associated with the occurrence of pathological vaginal discharge.

Comprehensive genomic profiling from C-CAT database unveiled over 80% presence of oncogenic drivers in anaplastic thyroid carcinoma including BRAF, RAS family, NF1, and FGFR1.

Anaplastic thyroid carcinoma (ATC) is considered a very aggressive carcinoma and has been difficult to treat with therapeutic strategies. This study examines the landscape of genomic alteration in ATC, including the BRAF V600E mutation, and its clinical implications. A retrospective observational study was conducted using collected at the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) in Japan, utilizing comprehensive genomic profiling data from 102 ATC cases. Additionally, AACR-GENIE data from 267 cases were analysed for validation. Statistical methods, including the conditional Kendall tau statistic and χ2 tests, were employed for survival analysis and gene mutation comparisons. Among 102 ATCs, BRAF, RAS, and other driver mutations were found in 83 cases (81.2%). The prevalence of BRAF V600E mutations was as high as 60%. Co-mutation analysis identified different genomic profiles in the BRAF, RAS, and wild-type groups. Despite the diverse molecular backgrounds, no significant differences in clinical variables and overall survival were observed. The analysis considering left-side amputation suggested that RAS mutations had a poorer prognosis. In the BRAF/RAS wild-type group, FGFR1 and NF1 were identified as driver mutations, with an accumulation of copy number variations and less TERT promoter mutations. This molecular subgrouping was also supported by the AACR-GENIE data. Comprehensive genomic analysis of ATC in Japan revealed distinct molecular subgroups, highlighting the importance of BRAF V600E mutations, particularly V600E, as potential therapeutic targets and suggest the relevance of tailor-made therapeutic strategies based on genomic profiling.

Application of fractional derivatives in image quality assessment indices

Objective image quality assessment involves the use of mathematical models to quantitatively describe image quality. FR-IQA (Full-Reference Image Quality Assessment) methods using reference images are also often used to evaluate image processing and computer vision algorithms. Quality indices often use gradient operators to express relevant visual information, such as edges. Fractional calculus has been applied in the last two decades in various fields such as signal processing, image processing, and pattern recognition. Fractional derivatives are generalizations of integer-order derivatives and can be computed using various operators such as the Riemann-Liouville, Caputo-Fabrizio, and Grünwald-Letnikov operators. In this paper, we propose a modification of the FSIMc image quality index by including fractional derivatives to extract and enhance edges. A study of the usefulness of fractional derivative in the FSIMc model was conducted by assessing Pearson, Spearman and Kendall correlations with MOS scores for images from the TID2013 and KADID-10k databases. Comparison of FD_FSIMc with the classic FSIMc shows an increase of several percent in the correlation coefficients for the modified index. The results obtained are superior to those other known approaches to FR-IQA that use fractional derivatives. The results encourage the use of fractional calculus.

What is the appropriate measure of radiology workload: Study or image numbers?

Previous studies assessing the volume of radiological studies rarely considered the corresponding number of images. We aimed to quantify the increases in study and image numbers per radiologist in a tertiary healthcare network to better understand the demands on imaging services. Using the Picture Archiving and Communication System (PACS), the number of images per study was obtained for all diagnostic studies reported by in-house radiologists at a tertiary healthcare network in Melbourne, Australia, between January 2009 and December 2022. Payroll data was used to obtain the numbers of full-time equivalent radiologists. Across all modalities, there were 4,462,702 diagnostic studies and 1,116,311,209 images. The number of monthly studies increased from 17,235 to 35,152 (104%) over the study period. The number of monthly images increased from 1,120,832 to 13,353,056 (1091%), with computed tomography (CT) showing the greatest absolute increase of 9,395,653 images per month (1476%). There was no increase in the monthly studies per full-time equivalent radiologist; however, the number of monthly image slices per radiologist increased 399%, from 48,781 to 243,518 (Kendall Tau correlation coefficient 0.830, P-value < 0.0001). The number of monthly images per radiologist increased substantially from 2009 to 2022, despite a relatively constant number of monthly studies per radiologist. Our study suggests that using the number of studies as an isolated fundamental data set underestimates the true radiologist's workload. We propose that the increased volume of images examined by individual radiologists may more appropriately reflect true work demand and may add more weight to future workforce planning.

Application value of multi-gene mutation detection in the clinical management of pediatric papillary thyroid carcinoma: a preliminary exploration.

Thyroid cancer rarely occurs in children and adolescents. Molecular markers such as BRAF, RAS, and RET/PTC have been widely used in adult PTC. It is currently unclear whether these molecular markers have equivalent potential for application in pediatric patients. This study aims to explore the potential utility of a multi-gene conjoint analysis based on next-generation targeted sequencing for pediatric papillary thyroid carcinoma (PTC). The patients diagnosed with PTC (aged 18 years or younger) in the pediatrics department of Lishui District Hospital of Traditional Chinese Medicine were retrospectively screened. A targeted enrichment and sequencing analysis of 116 genes associated with thyroid cancer was performed on paraffin-embedded tumor tissues and paired paracancerous tissue of fifteen children (average age 14.60) and nine adults (average age 49.33) PTC patients. Demographic information, clinical indicators, ultrasonic imaging information and pathological data were collected. The Kendall correlation test was used to establish a correlation between molecular variations and clinical characteristics in pediatric patients. A sample of 15 pediatric PTCs revealed a detection rate of 73.33% (11/15) for driver gene mutations BRAF V600E and RET fusion. Compared to adult PTCs, the genetic mutation landscape of pediatric PTCs was more complex. Six mutant genes overlap between the two groups, and an additional seventeen unique mutant genes were identified only in pediatric PTCs. There was only one unique mutant gene in adult PTCs. The tumor diameter of pediatric PTCs tended to be less than 4cm (p<0.001), and the number of lymph node metastases was more than five (p<0.001). Mutations in specific genes unique to pediatric PTCs may contribute to the onset and progression of the disease by adversely affecting hormone synthesis, secretion, and action mechanisms, as well as the functioning of thyroid hormone signaling pathways. But, additional experiments are required to validate this hypothesis. BRAF V600E mutation and RET fusion are involved in the occurrence and development of adolescent PTC. For pediatric thyroid nodules that cannot be determined as benign or malignant by fine needle aspiration biopsy, multiple gene combination testing can provide a reference for personalized diagnosis and treatment by clinical physicians.

Testing the Significance of Ranked Gene Sets in Genome-wide Transcriptome Profiling Data Using Weighted Rank Correlation Statistics.

Popular gene set enrichment analysis approaches assumed that genes in the gene set contributed to the statistics equally. However, the genes in the transcription factors (TFs) derived gene sets, or gene sets constructed by TF targets identified by the ChIP-Seq experiment, have a rank attribute, as each of these genes have been assigned with a p-value which indicates the true or false possibilities of the ownerships of the genes belong to the gene sets. Ignoring the rank information during the enrichment analysis will lead to improper statistical inference. We address this issue by developing of new method to test the significance of ranked gene sets in genome-wide transcriptome profiling data. A method was proposed by first creating ranked gene sets and gene lists and then applying weighted Kendall's tau rank correlation statistics to the test. After introducing top-down weights to the genes in the gene set, a new software called "Flaver" was developed. Theoretical properties of the proposed method were established, and its differences over the GSEA approach were demonstrated when analyzing the transcriptome profiling data across 55 human tissues and 176 human cell-lines. The results indicated that the TFs identified by our method have higher tendency to be differentially expressed across the tissues analyzed than its competitors. It significantly outperforms the well-known gene set enrichment analyzing tools, GOStats (9%) and GSEA (17%), in analyzing well-documented human RNA transcriptome datasets. The method is outstanding in detecting gene sets of which the gene ranks were correlated with the expression levels of the genes in the transcriptome data.

Association between heavy metal concentrations and chemotherapy-related acute adverse events in the patients with nasopharyngeal carcinoma: A prospective, longitudinal, observational study.

e18045 Background: Chronic exposure to heavy metals may cause chronic burden on liver, kidney, bone marrow and other organs. To determine whether the accumulation of heavy metals prior to treatment was related to the occurrence of acute adverse events in patients with nasopharyngeal carcinoma (NPC) receiving platinum-based chemotherapy, we conducted a single-center, prospective, longitudinal study. Methods: The heavy metal concentrations of pretreatment whole blood samples and the pretreatment and posttreatment morning urine samples for 140 NPC patients were measured, which were classified into low and high levels based on the 75% quartile. The highest grades of acute adverse events for every cycle of platinum-based chemotherapy were recorded according to the Common Terminology Criteria for Adverse Events (version 4.03). Wilcoxon rank-sum test was used to compare the difference in the distribution of acute adverse events between two levels. To illustrate the potential relationship of metal between in blood and urine, the spearman’s correlation coefficient of metal concentration in blood and urine adjusted by creatinine was calculated. The kendal's correlation coefficients were calculated to characterize the correlation between heavy metal levels and acute adverse events. Finally, the study developed multivariable adjusted logistic regression models to calculate odds ratios (OR) and 95% CIs of the association between various heavy metals and risk of chemotherapy-related acute adverse events, respectively. Results: The study enrolled 140 patients with stage II (n=2, 1.4%), III (n=76, 54.3%), and IVa (n=62, 44.3%) NPC. A total of 13 heavy metals of both blood and urine samples were measured, with Cd, Pb, Hg, As, Pt, Mg, Ca, Cr, Co, Ni, Cu, Zn, and Se included. The concentrations of the same metals in blood and urine (including Cd, Pb, Hg, As, Pt, Co and Se) had a moderate correlation (0.2 &lt; correlation coefficient &lt; 0.7). High level patients were prone to experiencing acute adverse events ( p&lt;0.05). In multivariable adjusted logistic regression, patients with impaired liver function had higher BCd (Cd in blood) level (OR, 3.65; 95% CI, 1.38–9.64; p=0.009). Patients with thrombocytopenia had higher UCr (Cr in urine) level (OR, 5.63; 95% CI, 1.60–19.87; p=0.007). And UPb (OR, 3.16; 95% CI, 1.26–7.92; p=0. 014) and UZn (OR, 2.69; 95% CI, 1.10–6.59; p=0. 030) were found significantly higher in patients with abnormal blood glucose. Conclusions: NPC patients with chronic accumulation of BCd had tendency to have impaired liver function when receiving platinum-based chemotherapy. Similar correlations were also observed in the thrombocytopenia with UCr, and the abnormal blood glucose with UPb and UZn.

Effect of ionizing radiation on JAK/STAT pathway and immune microenvironment in cervical cancer.

e17516 Background: STAT proteins play an important role in the development and progression of cervical cancer, and inhibition of the JAK/STAT pathway may be critical for enhancing tumor cell death. Delivering a certain dose of ionizing radiation (IR) directly to the lesion is one of the conventional treatments for cervical cancer. Whether IR will trigger changes in the JAK/STAT pathway and tumor immune microenvironment (TIME) is unknown and continues to be explored. Methods: We collected 30 patients received IR therapy with locally advanced cervical cancer (LACC) at the Affiliated Hospital of Qingdao University. Matched pre-IR and post-IR tumor tissue samples were collected from all patients, and the samples underwent RNA sequencing based on the nCounter platform (NanoString Technologies, Seattle, USA) and protein testing based on immunohistochemistry (IHC) staining. All tumor TIME cell infiltration scores were calculated as arithmetic mean of the constituent genes. P-values were calculated via the T Test. Results: RNA sequencing of tumor tissue from LACC patients before and after IR showed 35 differential genes. The results of GSEA pathway enrichment analysis of differential genes showed that compared with before IR, the IFN-α response pathway, IFN-γ response pathway and epithelial mesenchymal transition pathway were significantly up-regulated and enriched after IR. These three pathways collectively affect changes in the downstream JAK/STAT pathway. Moreover, compared with before IR, the cell infiltration abundance of overall macrophages (P=0.0087) and M2 macrophages (P=0.0043) increased significantly after IR. M1 macrophages also showed an increasing trend, but there was no statistically significant difference. In addition, further verification of changes in several proteins on the JAK/STAT pathway by IHC. The results showed that overall macrophages (P=0.0087) and M1 macrophages (P=0.026), PD-L1 (p=0.003), JAK1 (p=0.021) and STAT3 (p=0.018) were significantly increased after IR compared with before IR. M2 macrophages and STAT1 (p=0.734) also showed an increasing trend, but there was no statistically significant difference. It is worth noting that Kendall's tau-b correlation analysis was used to study the correlation of protein changes. The results found that the changes in PD-L1 expression before and after radiotherapy were related to STAT3 (Kendall's tau-b=0.487, P=0.02), JAK1 (Kendall's tau-b=0.513, P=0.015), there is a strong positive correlation. Conclusions: This study found that IR affects changes in cervical cancer TIME and these changes may promote the transition to an immunosuppressive phenotype. In addition, IR may affect changes in PD-L1 levels through the JAK1/STAT3 pathway. This needs to be further verified by designing large prospective clinical trials in the future.

Different Profiles of Jumper's Knee Indications in Basketball, Volleyball, and Football Athletes

PURPOSE: The present study aimed to compare the incidence of “jumper’s knee” injuries among athletes in basketball, volleyball, and football; to understand the causality and effect of the participation period and the incidence of jumper’s knee; to ascertain the link between history of injury and the incidence of jumper’s knee; and to determine the relationship between the type of tournament and the probability of jumper’s knee injury occurring.METHODS: This analytic, observational, cross-sectional study included subjects from high schools and clubs in Bandung, Solo, and Jogja, with a sample of approximately 30 participants representing each sport selected using a purposive sampling method (N = 93). Analytic observational using a cross sectional study approach in high schools and clubs in Bandung, Solo, and Jogja with a total sample of 30 for each sport selected by the purposive sampling method and obtained a total of 93 respondents. Dependent variable in this study is the jumper’s knee diagnosis. Statistical test data analysis used is different profiles using chi-square test effect of type of injury using binary regression relationship between participation period with jumper’s knee using Kendall's tau_b, the effect of playing time using binary regression and the relationship between the type of tournament and jumper’s knee using Kendall's tau_b. Statistical analysis of the dependent variable risk/indication for jumper’s knee used different methods. The chi-squared test was used to analyze the effect of type of injury using a binary regression method (Kendall's tau_b) to determine the relationship between participation period and jumper’s knee; and binary regression was used to assess the effect of playing time and the relationship between the type of tournament and jumper’s knee.RESULTS: Chi-squared analysis yielded an asymptotic significance value of p = .079, indicating no significant difference in the incidence of knee injuries among basketball, volleyball, and football athletes. Jumper's knee had positive percentage values of 38%, 34.6%, and 26.9% in basketball, volleyball, and football, respectively. Statistical tests examining the association between injury history and the incidence of jumper’s knee yielded a value of p = .00 with exp (b) = 0.075, which suggests an influence between ankle injury and jumper’s knee among the highest-risk athletes.CONCLUSIONS: Basketball, volleyball, and football players sustained jumper’s knee injuries at similar rates.

Fine-grained complexity-driven latency predictor in hardware-aware neural architecture search using composite loss

An efficient hardware-aware neural architecture search is crucial for automating the creation of network architectures that are optimized for resource-limited platforms. However, challenges arise owing to inaccuracies in key hardware performance metrics, notably in latency estimation. This study introduces a composite loss-based complexity-driven latency predictor, which is an innovative approach that achieves remarkable evaluation accuracy with limited training data. This reveals a robust correlation between the layer-based complexity features and network inference latency. This groundbreaking insight leverages these complex features as network architecture encodings for latency predictors, substantially enhancing the precision of latency assessments. In addition, a composite loss function is proposed that seamlessly integrates ranking and absolute performance losses. This novel approach addresses the limitations of rank-based loss methods, which often lack broader context. Incorporating a global perspective through absolute performance metrics significantly improves the generalization capabilities of the predictor across various benchmarks. Experimental results on the NAS-Bench-201, NAS-Bench-101, and MobileNetV3 benchmarks underscore the effectiveness of the predictor. For instance, in the NAS-Bench-201 evaluation, the predictor demonstrates a notable increase in Kendall's tau correlation, from 0.738 to 0.9733. These findings highlight the enhanced accuracy of the proposed approach with far-reaching implications for optimizing network structures on resource-limited platforms.

Physical Activity and Climacteric Symptoms Among Premenopause Women

Women experience physical changes before menopause. Women experience climacteric conditions caused by decreased reproductive hormones, so they experience the climacteric period. Climacteric is 4-5 years that occurs before menopause. Women experience problems during the climacteric period, such as hot flashes, sleep disorders, mood swings, and increased osteoporosis. Physical activity with conscious body movements produced by skeletal muscles requires energy expenditure. Physical activity includes all activities, with the intensity to help climacteric symptoms. This research aimed to identify the correlation between physical activity and climacteric symptoms. This research design used an analytical study with a cross-sectional approach. The sample was 72 women of premenopausal age, and it was obtained by cluster sampling. The research instrument was a questionnaire. The data analysis was the Kendal Tau test. The results of this study were 44.86 ± 3.041%, and the average number of children in this study was 2.76 ± 1.157%, elementary school education level was 47.2%, unemployed was 81.9%, respondents who did not use contraception hormonal and non-hormonal as many as 86.1%, respondents who did high physical activity were 93.1%, and respondents who did not have climacteric symptoms were 97.2%. The results of the Kendal Tau test showed a value (ρ value = 0.000), so there was a relationship between physical activity and climacteric symptoms in premenopausal women. In conclusion, physical activity has a relationship with climacteric symptoms in premenopausal women
