Weak Positive Correlation Research Articles

Correlation in retinal thickness and macular retina plus choroidal microcirculation in pediatric myopia.

To analyze the relationship in retinal thickness, macula retina and choroidal microcirculation in pediatric patients with myopia. Pediatric patients with high myopia (high myopia group, n = 30, 60 eyes) and pediatric patients with low to moderate myopia (low myopia group, n = 30, 60 eyes) admitted to our hospital from January 2021 to January 2022 were randomly selected as the study subjects. Retinal thickness, the blood density of retina, and the blood density of the choroid were collected in each area of the macula by taking optical coherence tomography (OCT) and OCT angiography (OCTA). Pearson correlation analysis was conducted to compare the results from the 2 groups. Outer retinal thickness showed a weak positive correlation with Superficial vascular complex flow density (SVD) and deep vascular complex flow density (DVD) (P < .05), but no significant correlation with choroidal capillary density (P > .05); inner retinal thickness showed a weak positive correlation with SVD and DVD (P < .05), but no significant correlation with choroidal capillary density (P > .05). In pediatric patients with myopia, there is a positive correlation between the blood flow density of macular retina and retinal thickness, and the retinal thickness will become thinner with increasing myopia.

Current urethroplasty trends in recent GURS fellowship graduates.

To assess self-reported urethroplasty success rates and outcomes of recent GURS fellowship graduates and compare these data to the large body of published urethroplasty outcomes literature. A voluntary survey was distributed from June 1 to June 30, 2023 to GURS fellowship graduates of the last 5 years. Participants were surveyed on time since graduation, operative volume, outcomes, and quoted success rates for urethroplasty. Data were then analyzed using descriptive statistics, binary logistic regression, and correlative analyses. We received responses from 49/101 (48.5%) GURS graduates. Five-year post-graduates were most represented (44.7%). The majority (52.2%) consider 81-90% of urethroplasty successful, without significant change with years in practice. Approximately 65% quoted excision and primary anastomosis (EPA) as > 90% successful. Over half of the respondents had performed > 60 urethroplasties since graduation. Only 31.3% of respondents reported re-intervening in > 10% of their postop patients, with a weak positive correlation between years in practice and need for re-intervention (p 0.01). Nearly 20% of respondents referred patients to an external reconstructionist. Increased length of time in practice does not result in higher reported urethroplasty success rates, counseling on successful outcomes, or rates of re-intervention and complications. Our survey highlights that the traditionally used success rates for urethroplasty may not be reflective of new graduates and lower volume reconstructive surgeons in their early career.

Translation and psychometric analysis of urdu version of modified polycystic ovary syndrome health related quality of life questionnaire (MPCOSQ-U)

BackgroundPolycystic ovary syndrome is a metabolic disorder prevalent among females of reproductive age. The symptoms of PCOS profoundly affect the quality of life of these females. Outcome measures specific to PCOS are crucial to the management of these patients. The MCPOSQ is a validated tool to measure the health-related quality of life specific to PCOS. The purpose of this study was to translate the modified polycystic ovary syndrome quality of life questionnaire (MPCOSQ) and to determine the reliability and validity of the modified polycystic ovary syndrome quality of life questionnaire Urdu version (MPCOSQ-U).MethodologyThis cross-sectional study was conducted in Islamabad/Rawalpindi. The MPCOSQ was translated to Urdu and validated by expert gynaecologists. The MPCOSQ-U and SF-36 were administered to one hundred eighty females with PCOS. The MPCOSQ-U was evaluated for internal consistency, test-retest reliability, factor analysis, face validity, content validity and construct validity.ResultsThe average age (years) of the females was 25.27(1.83). The MPCOSQ-U showed excellent test-retest reliability and internal consistency (ICC2,1=0.95, Cronbach’s α = 0.97). The content validity index (CVI) was 0.92. There was a statistically significant but weak positive correlation between MPCOSQ-U and SF-36 (r = .186, p = .012).ConclusionThe Urdu version of the modified version of the polycystic ovarian syndrome quality of life questionnaire is a validated and reliable tool to assess the quality of life of Pakistani females with PCOS. This is an important step to cover the language barrier, which influences the outcome assessment in PCOS.

Examining audiologist candidates' self-esteem and professional self-esteem

BackgroundSelf-esteem is an individual's perception of themselves. Professional self-esteem is defined as the individual's perception of worthiness regarding their preferred profession. The research aims to examine the relationship between the self-esteem and professional self-esteem of Audiology department students and raise awareness of this issue.Material and MethodIn our study, 532 students in the Audiology undergraduate department were included. Professional Self-Esteem and Self-Esteem questionnaires were delivered to the students online via Google Forms, using snowball sampling, in social media groups of the Audiology undergraduate students. Data were analyzed using Spearman correlation analysis, Mann Whitney U, and Kruskal Wallis Test. p < 0.05 was accepted as significance value.ResultsAccording to the results, it has been observed that there is a weak and significant positive correlation between the professional self-esteem of the audiologist candidates and their total self-esteem scores (p < 0.05). Self-esteem and professional self-esteem scores of those who chose the profession willingly were significantly higher than those who did not choose the profession willingly (p < 0.05). As the grade level increased, professional self-esteem decreased significantly (p < 0.05). There was no significant difference between the scores in both scales according to income, university type, and gender (p > 0.05).ConclusionAs a result, it was observed that as the self-esteem of the audiologist candidates increased, their professional self-esteem increased. Also, as the class level increased, their professional self-esteem decreased.

Distribution of Private Dental Healthcare Facilities in Riyadh City: A GIS-Based Approach.

The dental healthcare private sector in Riyadh city has been growing rapidly over the past few years; however, there is a lack of information on the accessibility and spatial distribution of private dental healthcare facilities (PDHFs) in the area. This study aimed to evaluate the spatial distribution of PDHFs in Riyadh city in relation to population density in each sub-municipality. The current information regarding the number, location, and operability of PDHFs in Riyadh city was obtained from the Ministry of Health. A total of 632 operating PDHFs were included with the precise location plotted on Quantum Geographic Information System software (version 3.32.1, Essen, Germany) using Google Earth. Four levels of buffer zones-1 km, 3 km, 5 km, and >5 km-were determined. The population statistics and mean monthly individual income per district were gathered from Zadd.910ths. Microsoft Excel (version 16.0, Microsoft, Redmond, WA, USA) and RStudio software (version 4.1.3, Posit Software, PBC, Boston, MA, USA) were used for additional data analysis. There was an overall ratio of one PDHF per 9958 residents in Riyadh city. Olaya and Maather sub-municipalities had the largest PDHF-to-population ratios: (1:4566) and (1:4828), respectively. Only 36.3% of the city's total area was within a 1 km buffer zone from a PDHF. There was an overall weak positive correlation between the number of PDHFs and the total area in each sub-municipality (r = 0.29), and the distribution of PDHFs was uneven corresponding to the area (G* = 0.357). There was an uneven distribution of PDHFs in Riyadh city. Some areas were underserved while others were overserved in several sub-municipalities. Policy-makers and investors are encouraged to target underserved areas rather than areas with significant clustering to improve access to care.

Interprofessional competency in clinical students: validating the Clinical student version of the Japanese Self-assessment Scale of Interprofessional Competency (C-JASSIC)

ABSTRACT In this study, we developed and validated the Clinical Student Version of the Japanese Interprofessional Competency Self-Assessment Scale (C-JASSIC) for healthcare students in their clinical practice phase. Data obtained from 331 students (medical, 98; nursing, 99; pharmacy, 134) during orientation for interprofessional education (pre-IPE) and from 319 students (medical, 94; nursing, 93; pharmacy, 132) within a week following IPE (post-IPE) were analyzed. Exploratory pre-IPE and Confirmatory post-IPE factor analyses revealed a consistent 6-factor structure aligning with the Japanese Interprofessional Competency domains. The scale exhibited strong internal consistency, with Cronbach’s α values exceeding 0.8 for all factors both pre- and post-IPE. Scores for overall competency and individual domains increased post-IPE in 234 matched cases. A notable significant pre vs post difference concerned “Understanding of Others,” indicating enhanced interprofessional comprehension after clinical practice. There was a weak but significant positive correlation between IPE satisfaction and difference in pre- and post-IPE scores. However, no significant differences were observed among medical, nursing, and pharmacy students. Despite its strengths, such as its competency-based design and cultural relevance to Japan, a limitation of the study may be potential self-reporting bias. Nonetheless, C-JASSIC represents a valuable tool for seamless competency evaluations from student to professional stages, with implications for broader Asian contexts.

The impact of primary schools’ inclusiveness on the inclusion of students with autism spectrum disorder

The inclusion of students with autism spectrum disorder (ASD) is a complex issue for schools. This study investigates the impact of the inclusivity of Slovenian primary schools on the inclusion of their students with ASD. We postulated that each pedagogical dimension of inclusion (i.e., academic, social, and emotional inclusion) of students with ASD would demonstrate a positive correlation with each dimension of inclusiveness of primary schools (i.e., inclusive culture, policy, and practice). Forty regular Slovenian elementary schools participated in the research. The Perceptions of Inclusion Questionnaire was completed by 200 respondents (40 students with ASD, 40 parents, 120 teachers), and the Index for inclusion by 240 respondents (40 parents, 200 school professionals). The analysis revealed one significant correlation, a weak positive correlation between inclusive practice and academic inclusion. Multiple regression analyses also identified one conditionally substantial pair. When we excluded the inclusive culture and policy and only considered the control of demographic variables, the results showed that the increase in inclusive practices corresponds to the increase in academic inclusion. The absence of correlations between the dimensions of school inclusivity and the pedagogical dimensions of including students with ASD can be attributed to the lack of systemic solutions for accommodating a diverse student population and the failure to conduct a thorough analysis of the inclusion and implementation of whole-school approaches. However, the Slovenian adaptation of the Index for Inclusion, a promising tool, offers hope in addressing these challenges.

Bruxism treatment on Youtube: evaluating reliability and information accuracy

BackgroundThe aim of this study was to evaluate the content and quality of videos about bruxism treatments on YouTube, a platform frequently used by patients today to obtain information.MethodsA YouTube search was performed using the keywords “bruxism treatment” and “teeth grinding treatment”. “The sort by relevance” filter was used for both search terms and the first 150 videos were saved. A total of 139 videos that met the study criteria were included in the study. Videos were classified as poor, moderate or excellent based on a usefulness score that evaluated content quality. The modified DISCERN tool was also used to evaluate video quality. Additionally, videos were categorized according to the upload source, target audience and video type. The types of treatments mentioned in the videos and the demographic data of the videos were recorded.ResultsAccording to the usefulness score, 59% of the videos were poor-quality, 36.7% were moderate-quality and 4.3% were excellent-quality. Moderate-quality videos had a higher interaction index than excellent-quality videos (p = 0.039). The video duration of excellent-quality videos was longer than that of moderate and poor-quality videos (p = 0.024, p = 0.002). Videos with poor-quality content were found to have significantly lower DISCERN scores than videos with moderate (p < 0.001) and excellent-quality content (p = 0.008). Additionally, there was a significantly positive and moderate (r = 0.446) relationship between DISCERN scores and content usefulness scores (p < 0.001). There was only a weak positive correlation between DISCERN scores and video length (r = 0.359; p < 0.001). The videos uploaded by physiotherapists had significantly higher views per day and viewing rate than videos uploaded by medical doctors (p = 0.037), university-hospital-institute (p = 0.024) and dentists (p = 0.006). The videos uploaded by physiotherapists had notably higher number of likes and number of comments than videos uploaded by medical doctors (p = 0.023; p = 0.009, respectively), university-hospital-institute (p = 0.003; p = 0.008, respectively) and dentists (p = 0.002; p = 0.002, respectively).ConclusionsAlthough the majority of videos on YouTube about bruxism treatments are produced by professionals, most of the videos contain limited information, which may lead patients to debate treatment methods. Health professionals should warn patients against this potentially misleading content and direct them to reliable sources.

Comparison of the Amyloid Plaque Proteome in Down Syndrome, Early-Onset Alzheimer's Disease and Late-Onset Alzheimer's Disease.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD), attributable to APP overexpression. DS exhibits Amyloid-β (Aβ) and Tau pathology similar to early-onset AD (EOAD) and late-onset AD (LOAD). The study aimed to evaluate the Aβ plaque proteome of DS, EOAD and LOAD. Using unbiased localized proteomics, we analyzed amyloid plaques and adjacent plaque-devoid tissue ('non-plaque') from post-mortem paraffin-embedded tissues in four cohorts (n = 20/group): DS (59.8 ± 4.99 y/o), EOAD (63 ± 4.07 y/o), LOAD (82.1 ± 6.37 y/o) and controls (66.4 ± 13.04). We assessed functional associations using Gene Ontology (GO) enrichment and protein interaction networks. We identified differentially abundant Aβ plaque proteins vs. non-plaques (FDR < 5%, fold-change > 1.5) in DS (n = 132), EOAD (n = 192) and in LOAD (n = 128); there were 43 plaque-associated proteins shared between all groups. Positive correlations (p < 0.0001) were observed between plaque-associated proteins in DS and EOAD (R2 = 0.77), DS and LOAD (R2 = 0.73), and EOAD vs. LOAD (R2 = 0.67). Top Biological process (BP) GO terms (p < 0.0001) included lysosomal transport for DS, immune system regulation for EOAD, and lysosome organization for LOAD. Protein networks revealed a plaque enriched signature across all cohorts involving APP metabolism, immune response, and lysosomal functions. In DS, EOAD and LOAD non-plaque vs. control tissue, we identified 263, 269, and 301 differentially abundant proteins, including 65 altered non-plaque proteins across all cohorts. Differentially abundant non-plaque proteins in DS showed a significant (p < 0.0001) but weaker positive correlation with EOAD (R2 = 0.59) and LOAD (R2 = 0.33) compared to the stronger correlation between EOAD and LOAD (R2 = 0.79). The top BP GO term for all groups was chromatin remodeling (DS p = 0.0013, EOAD p = 5.79×10- 9, and LOAD p = 1.69×10- 10). Additional GO terms for DS included extracellular matrix (p = 0.0068), while EOAD and LOAD were associated with protein-DNA complexes and gene expression regulation (p < 0.0001). We found strong similarities among the Aβ plaque proteomes in individuals with DS, EOAD and LOAD, and a robust association between the plaque proteomes and lysosomal and immune-related pathways. Further, non-plaque proteomes highlighted altered pathways related to chromatin structure and extracellular matrix (ECM), the latter particularly associated with DS. We identified novel Aβ plaque proteins, which may serve as biomarkers or therapeutic targets.

ESTIMATION OF STATURE FROM NASAL HEIGHT IN MALE AND FEMALE STUDENTS IN UDAIPUR

Objective: Stature refers to a person's height when standing upright. It is a vital measure of physical identity. In archaeological operations or forensic exams following a mass disaster, height is estimated using rudiments or bone pieces for identification. In order to determine stature, separate regression formulae should be developed for each population group. Methods: This cross-sectional study was conducted at Department of Anatomy, Pacific Institute of Medical Sciences, Umarda, and Udaipur. A total of 110 students (55 males and 55 females) aged between 18 to 25 y, participated in this study. Those with craniofacial defects were excluded from study. Height was measured from vertex to floor by stadiometer. Results: The study showed that in males mean values are significantly higher than females for both nasal height as well as stature; nasal height in (male 48.54±3.584 mm; female 46.75±3.763 mm) and stature in (male 170.3±7.902 cm; female 159.61±5.383 cm). In total student’s as well as in males and females, nasal height had a weak positive linear relationship with stature; r=0.283 in total students, r=0.222 for male and r=0.123 for female. The regression equation for stature and nasal height was found to be Y=134.053+0.648× nasal height for total students, Y=146.487+0.496×nasal height for males, Y=151.328+0.177× nasal height for females. Conclusion: The observed correlation is statistically significant in total students (p value&lt;0.05) but not significant in males and females (p value&gt;0.05). Overall nasal height had a weak positive linear correlation with stature.

Anti-Carbamylated Protein Antibodies in ACPA-Negative and ACPA-Positive Patients with Rheumatoid Arthritis.

. The study involved 150 patients with a reliable diagnosis of rheumatoid arthritis and 25 patients as healthy controls. Depending on ACPA values, two groups of patients were recruited: ACPA-positive (n = 75) and ACPA-negative (n = 75). RA activity was assessed by the DAS28 index. Determination of antibodies to carbamylated proteins was performed by enzyme-linked immunosorbent assay (BlueGene Biotech, China). Quantitative determination of ACPA in serum was performed by enzyme immunoassay using a commercial reagent kit (AxisShield, UK; upper limit of normal 5.0 U/mL; Orgentec, Germany; upper limit of normal 20.0 U/mL). . Median anti-CarP in patients with RA was 126.2 [100.83; 157.41] ng/mL and was statistically significantly higher (p < 0.001) than in healthy controls (88.89 [70.53; 107.75] ng/mL). Among all patients with RA, 50 (33.3%) were anti-Carp-positive (22 (29.3%) in the ACPA(+) group and 28 (37.3%) in the ACPA(-) group), and one (2%) volunteer from healthy controls was anti-CarP(+) (p = 0.002). In ROC analysis performed to assess the diagnostic significance of anti-CarP for RA for all patients with RA, the area under the curve was 0.783 ± 0.047 with 95% CI: 0.691-0.874 (p < 0.001), with a cut-off point of 143 ng/mL, specificity 96%, sensitivity 36.7%. In the ACPA(+) RA group, the erosion count was statistically significantly higher (p = 0.044) in anti-CarP(+) patients than in anti-CarP(-) patients. A weak direct correlation between anti-CarP and DAS28 was found in the ACPA(-) RA group. . We studied the predictive value of anti-CarP as an auxiliary biomarker in ACPA(+) and ACPA(-) subtypes of RA. ACPA(+) anti-CarP(+) patients have a more "erosive" subtype of the disease than ACPA(+) anti-CarP(-) patients. In ACPA(-) patients, anti-CarP helps to identify a more erosive subtype of the disease, and among ACPA(-) patients it helps to reduce the proportion of seronegative patients. Further studies are required to determine the optimal standards for the laboratory diagnosis of anti-CarP and to clarify the diagnostic potential of these ABs as part of the differential diagnosis of arthritis in other rheumatic diseases.

Correlation of Dance Functional Status with Lower Limb Flexibility, Power and Dynamic Balance in Recreational Ballet Dancers – A Cross-Sectional Study

Background: Paediatric ballet dancers are particularly prone to injuries due to the demanding nature of their art form, exacerbated by intensive training during crucial growth and maturation phases. The prevalence of injuries, especially those affecting lower limbs, hampers dancers’ functional capacity. Unlike their professional counterparts, recreational ballet dancers lack specialized training, heightening their vulnerability. The accumulation of repetitive injuries often hampers their ability to attain the highest levels of achievement in their careers, underscoring the necessity to identify and comprehend contributing factors. The aim is to fnd a correlation between the Dance Functional Outcome Survey (DFOS) and critical factors like lower limb flexibility, power, and dynamic balance among recreational ballet dancers. Methodology: 53 recreational ballet dancers aged 10–18 years with at least one year of dance experience were included. Lower limb flexibility was assessed using the sit and reach test, ankle flexibility, and straddle in supine tests, while power and dynamic balance were evaluated through vertical jump tests and Y balance tests. The DFOS questionnaire measured health status. Result: Results revealed statistically significant weak positive correlations between DFOS and various factors: sit and reach test (r=0.3060), ankle flexibility (r=0.3830), straddle in supine (r=0.3270), vertical jump test (r=0.3250), and Y balance composite (Right: r=0.3200; Left: r=0.3420). Conclusion: This study concludes that recreational ballet dancers with greater flexibility, power, and dynamic balance in the lower limb tend to exhibit a higher dance functional status. Keywords: paediatric, ballet dancers, flexibility, power, dynamic balance, Dance Functional Outcome Survey.

Hubungan antara Fanatik dengan Agresi pada Penggemar EXO

South Korean culture, especially K-pop, has achieved great global popularity. However, this popularity has also brought about a new phenomenon, namely fan culture which leads to intense fanaticism. This fanaticism often leads to aggressive behavior that occurs between competing fans. The approach used is quantitative research. The type of research used is quantitative correlational. The population in this study were EXO (EXO-L) Lombok fans, totaling 198 people. The technique used was purposive sampling and used a Krejcie table to determine the number of samples of 115 samples. Based on the findings of the research conducted, it can be said that there is a weak but significant positive correlation in the bigotry variable and the aggression variable with a correlation coefficient (R) value of 0.287 (indicating the same direction). There is a relationship between fanaticism and aggression in EXO fans with the result p = 0.002 (with p &lt; 0.01). These findings indicate that the higher the fanaticism shown by a fan, the higher the aggression towards the music group EXO and vice versa, the lower the fanaticism, the lower the aggression too. Advice for EXO fans to support idols with a positive attitude by respecting criticism, and using social media wisely can create a healthy and mutually supportive environment, which not only strengthens the relationship between idols and fans but also provides a positive example for other fans around the world

The mediating role of pediatric nursing competence in the relationship between pediatric drug administration self-efficacy and medical error tendency in nursing students

AimThis study was conducted to determine the mediating role of pediatric nursing competence in the relationship between self-efficacy in pediatric drug administration and medical error tendency in nursing students. BackgroundThe self-efficacy of nursing students towards drug administration knowledge and practices is one of the determinants of achieving the goals of nursing education programs related to drug administration. DesignThe sample of the descriptive and correlational study consisted of a total of 303 3rd and 4th-year students taking the Pediatric Health and Diseases Nursing course at the Department of Nursing. Data were collected using the Pediatric Nursing Competency Scale (PNCS), the Medication Administration Self-Efficacy Scale in Children for Nursing Students (MASSC) and the Medical Errors Tendency Scale (METS). Pearson correlation analysis, linear regression analysis, independent groups t-test, one-way analysis of variance (ANOVA) and post hoc (Tukey, LSD) test were used to analyze the data. In addition, hierarchical regression analyses regarding the mediation effect were performed using PROCESS Model 4 developed by Hayes (2013) for SPSS. ResultsWhen the correlation levels between the total scores of MASSC, PNSC and METS were analyzed, a positive moderate correlation was found between PNSC and MASSC total scores, a positive weak correlation was found between METS and MASSC total scores and a positive weak correlation was found between METS and PNSC total scores (p<0.05). As a result of the analysis, the model was found to be significant and the total change in METS was explained by 17.3 % of the total change in METS (F=63.289;p=0.000). It was found that PNSC was a partial mediator variable between MASSC and METS. ConclusionAs a result of the study, it was determined that pediatric nursing competence had a partial mediating role in the relationship between pediatric drug administration self-efficacy and medical error tendency in nursing students.

Phase Angle but Not Psoas Muscle Predicts Nutritional Risk and Prognosis in Males with Hepatocellular Carcinoma

Despite those with hepatocellular carcinoma (HCC) being at increased risk of malnutrition, there is a notable absence of practical approaches for nutritional assessment in clinical practice. We investigated the usefulness of phase angle (PhA) and Total Psoas Area Index (TPAI) for indicating nutritional risk and HCC prognosis. Weight, height, body mass index (BMI), adductor pollicis muscle thickness (APMT), and handgrip strength (HGS) were assessed. The Nutritional Risk Index (NRI) was calculated. Body composition was assessed using bioimpedance spectroscopy and magnetic resonance imaging. The Child-Turcotte-Pugh (CTP) score and Barcelona-Clinic Liver Cancer (BCLC) classification determined the prognosis. Fifty-one males with HCC were enrolled (CTP C = 11.8%). PhA showed a moderate positive correlation with APMT (r = 0.450; p < 0.001) and HGS (r = 0.418; p = 0.002) and a weak positive correlation with TPAI (r = 0.332; p = 0.021). PhA had a strong positive correlation with NRI (r = 0.614; p < 0.001). Mean PhA values were significantly different according to disease severity (CTP C p = 0.001, and BCLC D p = 0.053). TPAI had no significant correlation with HGS, CTP, or BCLC. PhA was a superior approach for predicting nutritional risk and prognosis in HCC than TPAI. Lower PhA is associated with disease progression, lower muscle mass and function, greater severity of nutritional risk, and increased mortality in HCC.

Association between carpal height ratio and ulnar variance in normal wrist radiography

IntroductionThe wrist joint is a complex anatomical structure, and various radiographic parameters are utilized to assess its normal alignment and orientation. Among these parameters are carpal height ratio (CHR) and ulnar variance (UV). Previous literature has indicated that factors such as age and gender may influence these parameters; However, there is a lack of studies investigating these differences specifically in the Middle East or Jordan. Additionally, no prior research has explored the relationship between UV and CHR. Therefore, the objective of this study is to investigate these critical radiological parameters and their associations.MethodologyA cross-sectional study design was employed, wherein a total of 385 normal wrist X-rays were reviewed, and CHR and UV were measured. Intra-observer and inter-observer reliability assessments were conducted to ensure the consistency and accuracy of measurements. Additionally, the association between UV and CHR was measured and plotted for further analysis.ResultsIn our study, the mean CHR was 0.5 (range: 0.4 to 1.5), and the mean UV was − 0.3 mm (range: -5.8 mm to 4.1 mm). We found a significant negative correlation between CHR and age (p < 0.05). No significant gender differences were observed in UV and CHR. Additionally, a weak positive correlation was found between UV and CHR (Pearson correlation coefficient = 0.13, p = 0.01; adjusted R2 = 0.014, p = 0.02).ConclusionAge correlated significantly with a decline in carpal height ratio. Additionally, ulnar variance had a week positive yet significant correlation with carpal height ratio.Level of evidenceCross-sectional study, Level III.

Assessment of oral health status and quality of life in hearing-impaired children from Syria

AimThis study aimed to evaluate the oral health status of children with hearing impairments and assess the relationship between various oral health factors and the Pediatric Oral Health-Related Quality of Life.Materials and methodsThis observational cohort study involved 90 hearing-impaired children aged 6–12 years. Diagnostic tools such as pure-tone audiometry were used to evaluate their hearing abilities. Dental health was assessed by calculating DMFT, dmft, Plaque and Gingival indices. The oral health-related quality of life was measured using the POHRQoL.ResultsThe severity of hearing impairment varied with 3% having severe hearing loss, 13% having profound hearing loss, and 83% having complete hearing loss. A high prevalence of dental cavities with 93% of children affected was found. DMFT score was similar between males and females (2.5 ± 0.3 vs. 2.3 ± 0.3 respectively). Males exhibited a higher mean dmft score (4.1 ± 0.5 vs. 3.3 ± 0.5), and a higher mean Plaque Index (1.9 ± 0.1 vs. 1.5 ± 0.1). On the other hand, females showed a higher mean Gingival Index (0.9 ± 0.1 vs. 1.1 ± 0.2). Results indicated a decreased OHRQoL with a mean POQL score of 6.4 ± 2.89. Spearman’s test revealed a significant positive correlation between POQL total score and DMFT scores (P = 0.000), dmft scores (P = 0.000), Plaque Index scores (P = 0.000), and Gingival Index scores (P = 0.038). There was a weak positive correlation between hearing impairment severity and POQL total score, it was not statistically significant.ConclusionsChildren who have hearing impairments exhibit poor oral health, and levels of dental caries, which can negatively impact their overall POHRQoL. Therefore, it is highly recommended to start specialized oral health education and comprehensive dental care programs to improve their OHRQoL.

Controls on Li partitioning and isotopic fractionation in inorganic calcite

The δ7Li of marine carbonates has been interpreted as an archive of the evolution of seawater δ7Li, and therefore continental weathering, through geological time. However, little is known about the incorporation of Li into calcium carbonate minerals and, consequently, the controls on Li partitioning (DLi) and isotopic fractionation (Δ7Lisolid-fluid) associated with Li incorporation. Crucially, we lack a fundamental understanding of how Li partitioning and Δ7Lisolid-fluid change in response to the chemical and physical conditions of crystal formation. Here, we present DLi and Δ7Lisolid-fluid data from a series of inorganic calcite precipitation experiments where temperature, and solution pH and dissolved inorganic carbon (DIC) were independently varied. We find DLi values in the range 0.8–1.5 × 10−3, which show no relationship with temperature, a strong positive correlation with pH, and a weak positive correlation with DIC. At face value, these patterns are inconsistent with the results of previous precipitation studies. However, the correlations with pH and DIC are consistent with a strong precipitation rate control on DLi that aligns well with previous data, with a likely secondary influence from the incorporation of Li-HCO30 ion pairs from solution. We find Δ7Lisolid-fluid values in the range −6 to −2 ‰, which show no relationship with temperature or pH, and a weak positive correlation with DIC and crystal precipitation rate. These results do not agree with previously published data. Considered alongside previously published data, we observe no consistent relationship between Δ7Lisolid-fluid and any reported physical or chemical experimental parameter, highlighting the need for substantial further work to determine whether systematic controls on Li isotopic fractionation exist in carbonate minerals, and whether they may be environmentally significant.

The relationship of IL-1β/IL-10 ratio, pain degree and CTX-II levels with histopathological features of facet joint osteoarthritis in patients with lumbal spinal canal stenosis

Introduction: Osteoarthritis of the facet joint is the final stage of spinal degeneration. Cytokines are believed to play a crucial role in degenerative joint diseases. This study was conducted to prove the relationship between the IL-1β/IL-10 ratio, the degree of pain, and the levels of CTX-II with the histopathological features of facet joint osteoarthritis in patients with lumbar spinal canal stenosis. Methods: The research design is a Cross-Sectional design with consecutive sampling. This study involves patients diagnosed with lumbar spinal canal stenosis according to the hospital's standard operating procedure from January 2023 to September 2023. CTX-II and Plasma IL-10 cytokine levels were examined using the Enzyme-Linked Immunosorbent Assay (ELISA) method. Histopathology is obtained through staining under a microscope. The data obtained in the study were analyzed, and significant result was p&lt;0.05. Results: A total of 38 samples were obtained. There were more males than females, with 52.6% and 47.4%, respectively. The demographic data showed an average age of 58 years. A statistically significant relationship was found between CTX-II and the histological degree of OA in facet joints, with a p-value of 0.043 (p &lt; 0.05) and a weak positive correlation strength (0.330). Meanwhile, the IL-1β/IL-10 ratio showed a weak positive correlation (0.490) with a p-value of 0.002. ODI exhibited a positive correlation with a strength of (0.393) and a p-value of 0.015. A statistically significant relationship was found for IL-1β with a p-value of 0.039, and IL-10 with a p-value of 0.031 (p &gt; 0.05). The correlation strengths were positive for IL-1β (0.327) and negative for IL-10 (-0.336). Conclusion: There was a relationship between the IL-1β/IL-10 ratio, the degree of pain, and the levels of CTX-II with the histopathological features of facet joint osteoarthritis in patients with lumbar spinal canal stenosis.

Structural phenotyping in atrial fibrillation with combined cardiac CT and atrial MRI: Identifying and differentiating individual structural remodelling types in AF.

Atrial remodelling (AR) is the persistent change in atrial structure and/or function and contributes to the initiation, maintenance and progression of atrial fibrillation (AF) in a reciprocal self-perpetuating relationship. Left atrial (LA) size, geometry, fibrosis, wall thickness (LAWT) and ejection fraction (LAEF) have all been shown to vary with pathological atrial remodelling. The association of these global remodelling markers with each other for differentiating structural phenotypes in AF is not well investigated. Patients referred for first-time AF ablation and controls without AF were prospectively recruited to undergo cardiac computed tomographic angiography (CCTA) and magnetic resonance imaging (MRI) with 3D atrial late-gadolinium enhanced (LGE) sequences. LAWT, atrial myocardial mass, LA volume and sphericity were calculated from CT. Biplane LA EF and LA fibrosis burden were derived from atrial MRI. Results were compared between patients with AF and controls. Forty two AF patients (64.3% male, age 64.6 ± 10.2 years, CHA2DS2-VASc 2.48 ± 1.5, 69.0% paroxysmal AF, 31% persistent AF, LVEF 57.9 ± 10.5%) and 37 controls (64.9% male, age 56.6 ± 7.2, CHA2DS2-VASc 1.54 ± 1.1, LVEF 60.4 ± 4.9%) were recruited. Patients with AF had a significantly higher LAWT (1.45 ± 0.52 mm vs 1.12 ± 0.42 mm, p = 0.003), tissue mass (15.81 ± 6.53 g vs. 12.18 ± 5.01 g, p = 0.011), fibrosis burden (9.33 ± 8.35% vs 2.41 ± 3.60%, p = 0.013), left atrial size/volume (95.68 ± 26.63 mL vs 81.22 ± 20.64 mL, p = 0.011) and lower LAEF (50.3 ± 15.3% vs 65.2 ± 8.6%, p < 0.001) compared to controls. There was no significant correlation between % fibrosis with LAWT (p = 0.29), mass (p = 0.89), volume (p = 0.49) or sphericity (p = 0.79). LAWT had a statistically significant weak positive correlation with LA volume (r = 0.25, p = .041), but not with sphericity (p = 0.86). LAEF had a statistically significant but weak negative correlation with fibrosis (r = -0.33, p = 0.008) and LAWT (r = -0.24, p = 0.07). AF is associated with significant quantifiable structural changes that are evident in LA size, tissue thickness, total LA tissue mass and fibrosis. These individual remodelling markers do not or only weakly correlate with each other suggesting different remodelling subtypes exist (e.g. fibrotic vs hypertrophic vs dilated). If confirmed, such a detailed understanding of the structural changes observed has the potential to inform clinical management strategies targeting individual mechanisms underlying the disease process.
