The Relationship

ABSTRACTSeveral methods of describing patterns of carpal kinematics from radiographs have emerged due to their potential use in developing personalized treatments for wrist pathologies. Such radiography-derived metrics have been used to infer associations between patterns of scaphoid kinematics and other clinically relevant factors such as sex, but the simultaneous effects of sex and wrist position on scaphoid kinematic metrics has yet to be considered. We sought to investigate the relationship between wrist position in the coronal plane and radiographic measurements of the scaphoid for each sex independently, then identify sex-specific differences in scaphoid measurements and calculated metrics. We retrospectively identified 38 subjects with posteroanterior radial and ulnar deviation radiographs. Radiographic scaphoid measurements were collected and used to calculate five scaphoid kinematic metrics per participant. We used Pearson correlation coefficients to explore the relationships between the degrees of wrist deviation in the coronal plane and radiographic scaphoid measurements for men and women independently. We used the non-parametric Wilcoxon signed-rank test to compare values between sexes. The correlations between degrees of coronal wrist deviation and radiographic measurements of scaphoid inclination were significant only for men. Men also had significantly greater values for all radiographic scaphoid measurements. Our study demonstrated sex-specific differences in the relationship between the degrees of radial and ulnar wrist deviation and scaphoid positioning.Clinical RelevanceOur findings show the importance of stratifying by sex in studies of carpal kinematics, such as scaphoid kinematics, and that investigation of strategies to restore normal carpal function should incorporate sex as a biological variable.

Abstract Background Suture anchor placement for subscapularis repair is challenging. Determining the exact location and optimum angle relative to the subscapularis tendon direction is difficult because of the mismatch between a distorted arthroscopic view and the actual anatomy of the footprint. This study aimed to compare the reliability and reproducibility of the navigation-assisted anchoring technique with conventional arthroscopic anchor fixation. Methods Arthroscopic shoulder models were tested by five surgeons. The conventional and navigation-assisted methods of suture anchoring in the subscapularis footprint on the humeral head were tested by each surgeon seven times. Angular results and anchor locations were measured and compared using the Wilcoxon signed rank test. Interobserver intraclass correlation coefficients (ICCs) were analyzed among the surgeons. Results The mean angular errors of the targeted anchor fixation guide without and with navigation were 17° and 2° (p < 0.05), respectively, and the translational errors were 15 and 3 mm (p < 0.05), respectively. All participants showed a narrow range of anchor fixation angular and translational errors from the original target. Among the surgeons, the interobserver reliabilities of angular errors for ICCs of the navigation-assisted and conventional methods were 0.897 and 0.586, respectively, and the interobserver ICC reliabilities for translational error were 0.938 and 0.619, respectively. Conclusions The navigation system may help surgeons be more aware of the surrounding anatomy and location, providing better guidance for anchor orientation, including footprint location and anchor angle.

Aim. The aim of this report is to identify variables determining the effectiveness of small football games at subsequent stages of training. Material and Methods. The study material comprised the results of tests conducted among 42 football players who were assigned to 3 categories: youngsters, younger juniors and seniors. The scope of the study included basic somatic features, selected motor skills tests and specific coordination tests of motor skills recommended for football players. Detailed correlation matrices were calculated using Spearman’s signed-rank test between all the analysed variables and the overall game perforance index (OPI). For each training group, morpho-functional profiles were calculated taking variables from previous analyses into account. Variables forming the structure of these models were normalised on the T scale. Results. 11 statistically significant Spearman’s signed-rank correlation coefficients were obtained between game performance indices and the analysed variables. In the 3 training groups of football players, considerable diversity of the internal structure of morpho-functional models was noted. In the group of juniors and seniors, differentiation between features was 1.2 of standard deviation. Conclusions. In terms of fitness, the influence of circulatory-respiratory endurance and speed ability on the indicator of overall performance for the seniors’ game was noted. In turn, taking the neuro-functional side of the players’ motor ability into account, correlations with the effectiveness of the game were mainly found within the ability of balance, kinesthetic differentiation and motor adaptation. Such regularities mainly refer to the youngsters and younger juniors.

Objective. To validate an audio-video (AV) method of food journaling, in a free-living scenario, compared to direct, weighed food assessment. Design and Setting. Data were collected in a cafeteria. Meals, selected by participants (n=30), were documented using the AV method: participants video-recorded their tray while audio-recording a description of their selected meal, after which the research team digitally weighed each food item and created an itemized diary record of the food. Variables Measured. Data from the AV method and from the weighed food diaries were transcribed and entered into a nutrition software analysis program (Nutribase Pro 10.0). Nutrient outputs were compared between the two methods including kilocalories, macronutrients, and selected micronutrients. Analyses. Using mean scores for each variable, Wilcoxon signed-rank test and Spearman’s correlation coefficients were conducted. Interclass correlation coefficient (ICC) was calculated for absolute agreement between the two methods to assess interrater reliability. Results. With the exception of Vitamin E and total weight, nutrient values were highly correlated between methods and were statistically significant given alpha = 0.05, power = 0.95, and effect size of 0.70. Conclusions. The AV method may be a meaningful alternative to diary recording in a free-living setting.

4573 Background: Preclinical models show that c-Met promotes survival of renal cancer cells through the regulation of programmed death-ligand 1 (PD-L1). The relationship between c-Met and PD-L1 in human ccRCC is not well characterized. We compared c-Met expression between primary and metastatic sites in ccRCC tissues and evaluated the association with PD-L1 expression. Methods: Pairedprimary and metastatic samples from 45 ccRCC patients were included. Areas with predominant and highest Fuhrman nuclear grade (FNG) were selected. c-Met expression was evaluated by IHC using an anti-Met monoclonal antibody (MET4 Ab, VARI) and calculated by a combined score (CS, 0-300) as: intensity of c-Met staining (0-3) x % of positive cells (0-100). PD-L1 expression was previously assessed by IHC (PMID: 26014095). c-Met expression (average c-Met CS) between paired primary and metastatic samples were compared using Wilcoxon signed-rank test. Associations of c-Met expression with PD-L1 expression (+/-) and other clinical features were assessed with Wilcoxon rank-sum tests. Results: Our cohort included 45 primary ccRCCs and 54 corresponding metastases. c-Met expression was higher in metastatic sites compared to primary (c-Met CS: 55 vs. 28, p=0.0003) and was numerically-greater in PD-L1+ vs. PD-L1- tumors. Higher c-Met expression was associated with higher FNG and T-stage in both primary and metastatic sites (Table). Conclusions: Higher c-Met expression in metastases compared to paired primary tumors in our cohort of ccRCC suggests that testing for biomarkers of response to c-Met inhibitors should be conducted in metastases. Although the observation of higher c-Met expression in PD-L1+ tumors requires further investigation, it supports exploring these targets in combination trials. [Table: see text]

Objectives We performed a retrospective review to compare a subjective parental proxy-derived voice handicap survey to an observer-derived method of measuring voice perturbation in children who have undergone airway reconstruction. The main outcome measures were the Pediatric Voice Handicap Index (pVHI) total score and the Overall Severity score on the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Methods The percent Overall Severity CAPE-V score (score divided by 100) and the percent pVHI score (score divided by 92) were calculated. A Wilcoxon signed rank test was used to compare CAPE-V scores with the pVHI total scores. The relationship between the pVHI scores and the CAPE-V scores was investigated with a Spearman correlation. Subgroup analysis was performed to determine the relationship of surgery type to CAPE-V and pVHI scores. Results Fifty subjects with a history of airway surgery who were evaluated between 2005 and 2008 were identified. Forty-two of the 50 subjects had complete data for review. Their median age was 7.1 years (range, 3.3 to 17.9 years). Their pVHI total scores had a median of 30 (range, 1 to 80). Their Overall Severity CAPE-V scores had a median of 50.5 (range, 0 to 98). Their median CAPE-V percent was higher than their median pVHI percent (50.5% versus 32.6%; p = 0.0003). A weak correlation was found between the Overall Severity CAPE-V score and the pVHI total score (rho = 0.41; p = 0.0003). There was a trend toward higher Overall Severity CAPE-V scores in patients who underwent cricotracheal resection. The total number of airway surgeries was significantly correlated with the Overall Severity CAPE-V score (rho = 0.6; p < 0.0001) but not with the pVHI score. Conclusions Children who undergo airway reconstruction often have a resulting voice disturbance that can affect their lives in multiple dimensions. The results of this study revealed a weak-to-fair correlation between the parent-reported pVHI total score and expert ratings of voice quality using the CAPE-V. In this patient population, both of these tools provided important information regarding the relationship of the severity of voice disturbance to its handicapping effects.

Previous research has studied the impact of corporate governance on bank performance, but only a few aspects of the impact were reported. The present study develops a unique corporate governance index to provide a comprehensivemeasure of corporate governance and examines the relationship between this comprehensive measure and bank performance. We apply the Wilcoxon signed rank test to examine whether the introduction of the Code of CorporateGovernance in Bangladesh has significantly promoted the improvement of corporate governance practices in Bangladeshi banks. Our results provide support for the hypothesis that corporate governance practices of Bangladeshi banks have been significantly improved since the introduction of the code. Further, the present study adopts regression analysis and reveals that the comprehensive measure of corporate governance is not significantly related to Bangladeshi banks’ performance.

ABSTRACT Background and Aims: There is no study in the literature that investigates an asymmetric morphological feature of the frontal sinus (FS). Materials and Methods: Four hundred and sixty-nine consecutive direct X-rays of FSs were analyzed for the asymmetry between the right and left sides. When an asymmetry in the height and contour of the FS existed, this difference was quantified. Results: Of the 469 patients, X-rays of 402 patients (85.7%), there was an asymmetry between right and left sides of the FS. Of these 235 (50.1%) were dominant on the left side, whereas 167 (35.6%) were dominant on the right, the sinuses of remaining 67 patients (14.3%) was symmetric. Statistical Analysis: The comparisons between parameters were performed using Wilkinson signed rank test. The relationship between handedness and sinus asymmetry was also examined by two proportions test. There is statistically significant difference between the dominance of left and right FS. Conclusions: Hemispheric dominance may have some effect (s) of on sinus asymmetry of the human cranium. Surgeons sometimes enter the cranium through the FS and knowledge of asymmetric FS is important to minimize surgical complications.

Aim was to evaluate the usability of mini-screw (Temporary Anchorage Devices TADs), as an anchor unit (units), in the treatment of gummy smile associated with deep over-bite. The sample was made up of 15 adult gummy smile patients (2males and 13 females).Materials and Methods All patients suffered from increased anterior facial height. Pre-treatment and post-intrusion gingival smile line (GSL), which is the distance between cervical gingival margins of maxillary central incisors and the lower border of the upper lip during smiling, was measured in millimetres using a digital calliper. Four TADs were used for each patient: two anterior TADs that were inserted between the roots of lateral incisors and canines; and the other two TADs were inserted posteriorly, between the roots of 2nd premolars and 1st molars. The anterior TADs were used as anchor units for the intrusion of upper anterior teeth, while posterior TADs were used for en-mass retraction. Pre-treatment and post intrusion lateral cephalometric radiographic measurements were taken for statistical inferences. Statistical analyses were carried out using Wilcoxon signed rank test. Statistical analyses revealed significant reduction in GSL and overbite.Results Radiographically, there were significant changes in the vertical and antro-posterior positions of upper anterior teeth, but no significant changes have been noticed in the vertical position of upper or lower posterior teeth.Conclusions The findings of the present study indicate that gummy smile which is mainly due to maxillary dentoalveolar overgrowth can be treated effectively with intrusion using anterior TADs, particularly in case of divergent face. The findings also indicate that anterior and posterior TAD scan provide absolute anchorage for treatment of deep overbite, and increased overjet.

Category: Arthroscopy Introduction/Purpose: The Posterior Ankle Impingement Syndrome (PAIS) can be treated by the endoscopic technique with posterior portals and patient in prone position. There is discussion whether this would be the best method, given the possible difficulty in learning and applying this technique, risks of complications and prolonged time of surgery. We conducted this retrospective study to assess the time spent to perform the posterior endoscopy along the learning curve and the relationship of the duration of the procedure to the presence of complications. Methods: We evaluated 39 patients undergoing endoscopic treatment through posterior ankle portals technique and prone position, operated by a single surgeon between 2005 and 2014. We divided the patients into four groups of ten subjects according to the chronological sequence of the surgeries. We used the Jonckheere-Terpstra test to compare the surgery time between the four analyzed groups. We used the Mann-Whitney test to compare operative time and the occurrence of complications, and the relationship between surgical procedure time and presence of intraoperative fibrosis. We used the Wilcoxon signed-rank test to compare preoperative and postoperative AOFAS Ankle-Hindfoot Score. For all statistical analysis, p-values <0.05 were considered to be significant. Results: We found a significant decreasing of the surgery duration over time (p=0.0273) (Figure). Figure: Representing surgery time (in minutes) to groups of patients (Groups 1 to 4, being Group 1 patients 1-10, Group 2 patients 11-20, Group 3 patients 21- 30 and Group 4 patients 31-39).There were three complications not related to the duration of the surgery (p=0.6909). The presence of extensive fibrosis had an impact on the operative time (p=0.0387). The AOFAS Score evolved from 64.0±16.9 preoperatively to 93.7±8.9 postoperatively (p<0.0001). Conclusion: The time of the procedure decreased as the surgeon’s experience increased, and our complications showed no relationship with the surgery time.

AbstractObjectiveTo assess the errors between estimates of amounts based on photographs and actual quantities of food presented to adults or eaten on the previous day.DesignA photographic atlas was constructed by taking digital photographs of three pre-weighed portion sizes of 212 traditional Lebanese dishes. In a first approach, ten portions of real pre-weighed foods were assessed using the photographic atlas. In a second approach, the participants weighed all foods consumed at one meal and recalled the amount of food that was eaten the previous day using the photographic atlas. Differences between actual quantities and estimation were assessed using a signed rank test (P< 0·05). Spearman's correlation coefficients and bias (Bland–Altman plot) between the methods were calculated.SettingLebanese university canteen and Lebanese homes.SubjectsForty adults (twenty males, twenty females) completed the first protocol and fifty adults (twenty-five males, twenty-five females) completed the second protocol; all were volunteers aged 21 to 62 years.ResultsMean differences between actual and estimated portion sizes by photographs were between −13·1 % and +24·5 % when pre-weighed foods were presented, and between −10·4 % and +3·8 % when foods were consumed the day before. No significant differences were found between actual and estimated portion sizes except for three dishes (loubieh bil zeit,tabboulehandyachnet bazella). Bland–Altman plots showed good agreement for all dishes with a negligible bias of −0·2 g between estimated and presented portions, and −6·3 g between estimated and eaten portions.ConclusionsIn the Lebanese diet, food photographs seem a reliable tool for quantification of food portion sizes.
