Nose shape, size, and inclination influence facial appearance, but few studies concern the relationship between the nasal profile and craniofacial structures. The objective of this study was to analyze association of nasal cephalometric variables with skeletal structures, age, and sex. Cephalometric and nasal analysis was performed in 386 Polish orthodontic patients (aged 9–25 years). Student t-test and Mann–Whitney test were used to compare quantitative variables and Pearson’s or Spearman’s correlation coefficients—to find correlations. Soft tissue facial convexity angle correlates to Holdaway ratio, ANB (A-Nasion-B), and Wits appraisal. Nasal dorsum axis, nose length, nose depth (1) and nose depth (2), nose hump, lower dorsum convexity, and columella convexity increase with age. Nasal base angle, nasolabial angle, nasomental angle, soft tissue facial convexity and nasal bone angle decrease with age. Nasal base angle and nasomental angle are smaller in females. Thus, a relationship exists between nasal morphology and sagittal jaw configuration. Nasal parameters significantly change with age. Sexual dimorphism characterizes nasal bone angle and nasomental angle.

Abstract Background In patients with primary hyperoxaluria (PH), endogenous oxalate overproduction increases urinary oxalate excretion, leading to compromised kidney function and often kidney failure. Highly elevated plasma oxalate (Pox) is associated with systemic oxalate deposition in patients with PH and severe chronic kidney disease (CKD). The relationship between Pox and estimated glomerular filtration rate (eGFR) in patients with preserved kidney function, however, is not well established. Our analysis aimed to investigate a potential correlation between these parameters in PH patients from three randomized, placebo-controlled trials (studies OC3-DB-01, OC3-DB-02, and OC5-DB-01). Methods Baseline data from patients with a PH diagnosis (type 1, 2, or 3) and eGFR > 40 mL/min/1.73 m2 were analyzed for a correlation between eGFR and Pox using Spearman’s rank and Pearson’s correlation coefficients. Data were analyzed by individual study and additionally were pooled for Studies OC3-DB-02 and OC5-DB-01 in which the same Pox assay was used. Results A total of 106 patients were analyzed. A statistically significant inverse Spearman’s correlation between eGFR and Pox was observed across all analyses; correlation coefficients were − 0.44 in study OC3-DB-01, − 0.55 in study OC3-DB-02, − 0.51 in study OC5-DB-01, and − 0.49 in the pooled studies (p < 0.0064). Conclusions Baseline evaluations showed a moderate and statistically significant inverse correlation between eGFR and Pox in patients with PH already at early stages of CKD (stages 1–3b), demonstrating that a correlation is present before substantial loss in kidney function occurs.

Purpose: Osteoarthritis is a progressive disease and the most common form of joint inflammation. Moreover, it is the most common cause of functional disability in the elderly. Among the multiple and predisposing factors influencing the disease are demographic indicators and occupational factors. The present study aimed to investigate the relationship between age, pain severity, Body Mass Index (BMI), occupation, and educational level, and the severity of functional disability in patients with Knee Osteoarthritis (KO). Methods: This descriptive study was performed on 97 KO patients referring to the Novin private physiotherapy clinic of Semnan University of Medical Sciences from April to March 2017. The study participants were selected through a simple nonprobability sampling technique. Literate individuals with the educational level of guidance school and above and diagnosed with KO were included in the study. Individuals with a history of inflammatory arthritis diseases, such as rheumatoid arthritis, soft tissue rheumatoid arthritis, fibromyalgia syndrome, bursitis, tendonitis, the neurological and vascular conditions of the lower extremity, mental problems, and malignancy were excluded from this research. The data related to the variables such as age, gender, occupation, history of osteoarthritis, pain intensity, involved side, educational level, and the Knee Injury and Osteoarthritis Outcome Score (KOOS) for knee disability were collected by a self-report questionnaire. This study was approved by the Research Ethics Committee of the University of Social Welfare and Rehabilitation Sciences. Using SPSS, Spearman’s correlation coefficients were calculated to examine the relationship between the study variables. Results: Spearman’s correlation coefficients revealed no significant correlation between the KOOS scores and age, occupation, and educational level. The obtained results suggested a poor significant association between KOOS and BMI; however, there was a strong significant correlation between KOOS and pain intensity Visual Analogue Scale (VAS) (P<0.05). Conclusion: The severity of functional disability in patients with KO based on KOOS questionnaire scores, was well correlated with pain severity, but poorly associated with age and BMI. The obtained data indicated no significant relationship between disability and occupation and educational level.

ABSTRACT Objective: The purpose of this prospective observational study was to evaluate the relationship between nasal morphology and maxillary skeletal pattern. The clinical significance was to emphasize the importance of role of nasal pattern in diagnosis and treatment planning. Materials and Methods: The sample included the pre-treatment lateral cephalometric radiographs of 180 South Indian adults (94 women, 86 men), aged 18 to 28 years. Six maxillary and six nasal soft tissue parameters were measured. Pearson correlation coefficients and Analysis of variance were used for statistical analyses. Results: There were significant correlations between maxillary vertical and sagittal, skeletal and soft tissue parameters. The Mean and standard deviations were correlated between low insignificant range to high significant levels with nasal length, nasal depth and columella convexity. Nasal length also showed significant correlation with inclination of palatal plane. Significant influence of gender was seen on nasal length, nasal depth, columella convexity and nasal tip angle. A statistically significant difference was seen regarding nasal length between males and females, with nasal length being more in males (50.26 ± 4.18) than in females (48.86 ± 3.45), nasal depth being more in males (18.64 ± 2.56) than in females (16.63 ± 2.16), columella convexity being greater in males (4.31 ± 1.26) than in females (3.41 ± 1.13), nasolabial angle decreased in males (87.26° ±13.79°) than in females (89.38° ±15.72°) and nasal tip angle being more in females (80.18° ±9.44°) than in males (73.60° ±10.24°). There was no statistically significant difference in nasal hump between males (-2.01 ± 1.76) and females (-2.02 ± 1.62). Conclusion: Long nose with increased nasal prominence were seen with increase in the anteroposterior length and vertical height of maxilla. Male and female genders had a varied amount of nasal length, nasal depth and columella convexity along with nasal tip angle.

Abstract The North Atlantic Oscillation (NAO) is the most important circulation phenomenon in the Northern Atlantic which impacts climate in Europe in various ways. Precipitation is a basic climatic element which affects the landscape significantly. Therefore in this paper, the relationship between the NAO and winter precipitation in Slovakia is analysed. A Spearman’s correlation analysis was used, which detected the impacts of NAO on the above-mentioned seasonal precipitation in different regions of Slovakia. The correlation coefficients obtained positive values in the region of Orava and Kysuce and changed to negative ones in a southward direction. The detected zonal configuration can be explained by the topographic barrier effect of the Carpathians

Abstract Background: The craniofacial morphology and blood groups both are related to genetic components, hence it can be hypothesized that blood groups have an association with craniofacial morphology. Some studies showed the relationship whereas others could not find any relationship that may be due to geographic diversity of the population. The aim of this study was to find out the relationship between ABO blood groups and craniofacial morphology among orthodontic patients of Kathmandu district. Materials and Methods: In this cross sectional study, a total of 385 participants (age range from 13-45 years) were selected among the orthodontic patients who came for orthodontic treatment in private orthodontic clinics. After obtaining written consent, all the patient’s demographic information were recorded and lateral cephalograms were obtained from the patient’s record. Blood group of all the participants was recorded. Results: The study found that among the total of 385 participants, 162 (42.07%) were male while 223 (57.93%) were female and the mean age was 16.31±4.38 years. Twenty cephalometric parameters depicting craniofacial morphology were digitally analyzed using lateral cephalogram. The prevalence of blood group O patients was highest (32.20%) followed by blood group B (30.64%), blood group A (29.88%) and blood group AB (7.28%). Statistical analysis with one way ANOVA was used for association of numerical data and blood groups that revealed nine out of twenty cephalometric parameters were statistically significant among different blood groups (p<0.05). Tukey post hoc test was done to find out where the significant difference occurs among the groups. Conclusions: The evaluation of the relationship between blood group and craniofacial morphology revealed that blood groups have association with some craniofacial parameters. This suggest, there may be some genetic influence of ABO blood group on craniofacial morphology. Keywords ABO blood groups, Craniofacial morphology, Association, Orthodontic patients

The aim of the research is to determine the ranking of voivodships in the field of economic innovativeness and development as well as to assess the relationship between these phenomena. The article presents theoretical fundamentals of issues connected with innovation and economic development. Attention was also paid to the impact of innovation on the region's economic development. In the first stage of the analysis, rankings of voivodships in terms of innovation and economic development for 2005 and 2015 were created using the methods of taxonomic ordering of objects. Subsequently, an attempt was made to assess the correlation between the two rankings using Spearman's correlation coefficients. Basing on literature study and own research results, the thesis that at present innovativeness is one of the most significant factors of growth and economic development was confirmed. Innovations, especially the crucial ones, serve as the driving force of growth and thus of economic development.

Purpose The minimum masking level (MML) is the minimum intensity of a stimulus required to just totally mask the tinnitus. Treatments aimed at reducing the tinnitus itself should attempt to measure the magnitude of the tinnitus. The objective of this study was to evaluate the reliability of the MML. Method Sample consisted of 59 tinnitus patients who reported stable tinnitus. We obtained MML measures on two visits, separated by about 2–3 weeks. We used two noise types: speech-shaped noise and high-frequency emphasis noise. We also investigated the relationship between the MML and tinnitus loudness estimates and the Tinnitus Handicap Questionnaire (THQ). Results There were differences across the different noise types. The within-session standard deviation averaged across subjects varied between 1.3 and 1.8 dB. Across the two sessions, the Pearson correlation coefficients, range was r = .84. There was a weak relationship between the dB SL MML and loudness, and between the MML and the THQ. A moderate correlation ( r = .44) was found between the THQ and loudness estimates. Conclusions We conclude that the dB SL MML can be a reliable estimate of tinnitus magnitude, with expected standard deviations in trained subjects of about 1.5 dB. It appears that the dB SL MML and loudness estimates are not closely related.

The study evaluates the relationship between Emotional Intelligence and Leadership Effectiveness through a Systematic Review of Literature. The relationship has been evaluated in two steps. First, a Systematic review of literature was done to provide a theoretical framework to link the dimensions of Emotional Intelligence to the elements of effective leadership. Meta-analysis was then used to consolidate empirical evidence of the relationship. The studies for the meta-analysis were sourced from Pro Quest and EBSCO and the correlation coefficients of the studies were analysed. Only articles that presented the direct relationship between the variables were included in the study. The results of the analysis revealed a strong, statistically significant relationship between emotional intelligence and effective leadership. The findings of the study provide evidence for the proposition that Emotional Intelligence and Leadership Effectiveness are interrelated.
