Abstract Background The Rustogi et al. Modified Navy (RMNPI) and Turesky et al Modification of the Quigley Hein (TQHPI) plaque indices are commonly used to measure plaque removal. This study evaluated the possible correlations of both indices using data relative to a single use assessment of plaque removal using commercially available toothbrushes. Methods Single use crossover study designs have been previously reported. Disclosed plaque was scored pre- and post-brushing using both the RMNPI and the TQHPI. Sixty subjects, with an initial mean RMNPI score of 0.6 or greater, were enrolled and completed the study. No minimum score was required for TQHPI. After the initial scoring, the order for each index was randomized so that each subject was scored with either RMNPI followed by TQHPI or vice versa. Two manual toothbrushes [Oral-B® CrossAction® (CA) and Colgate® Navigator. (NA)] and one battery-powered brush (Crest® SpinBrush. Pro) (SBP) were evaluated in the trial. One examiner performed all clinical measurements. Pearson correlations were performed on whole mouth, buccal, and lingual plaque scores for the CA toothbrush. Results Strong positive correlations were found between the two plaque indices for pre- and post-brushing scores for the whole mouth and on lingual and buccal surfaces, where Pearson correlation coefficients ranged between 0.963 and 0.995. There was no correlation between the pre-brushing plaque score and the amount of plaque removed by brushing indicating that higher plaque levels before brushing do not necessarily predict that greater amounts of plaque will be removed during toothbrushing. Each toothbrush was found to be safe and significantly reduced plaque levels after a single brushing (t-test, p=0.0001). Significantly greater plaque reductions were found with the CA than the NA and SBP toothbrushes at whole mouth, lingual, and approximal surfaces for both indices (analysis of variance (ANOVA), p . 0.0002 for all comparisons). Conclusions Strong positive correlations were found between two plaque indices (the RMNPI and TQHPI) for pre- and post-brushing scores at whole mouth, lingual, and buccal surfaces as assessed using data from a single use assessment of plaque removal. Efficacy data from this study demonstrated the CA toothbrush provided superior cleaning when compared to the NA manual toothbrush and SBP battery toothbrush. Clinical Implications Two commonly used indices for assessing plaque removal in clinical studies are RMNPI and TQHPI. However, each index differs in the way plaque is scored. This study used both indices to assess comparative toothbrush efficacy and showed a strong correlation between indices for both pre- and postbrushing plaque scores. The result suggests that both indices demonstrate sufficient sensitivity to differentiate toothbrush efficacy. Citation Cugini M, Thompson M, Warren PR.

Clinical Measurements

The maximal passive ankle dorsiflexion angle and the maximal passive resistive torque at this angle were measured for 81 women 20 to 84 years of age and correlated with the passive-elastic stiffness (stiffness) of an ankle dorsiflexion stretch. Pearson correlation coefficients and multiple regression analyses were used to examine whether the two clinical measurements could predict ankle stiffness. The maximal passive resistive torque showed a moderate correlation with stiffness in the full stretch range ( r = .69) and high correlation with stiffness in the last half of the full stretch range ( r = .84). The maximal dorsiflexion angle showed a low correlation with stiffness in the full stretch range ( r = .27) and in the last half of the full stretch range ( r = .36). The maximal passive resistive torque and the dorsiflexion angle together accounted for 54% of the stiffness variance in the full stretch range and 76% of the stiffness variance in the last half of the full stretch range. Thus, the clinical measurements of the maximal passive dorsiflexion angle and the maximal passive resistive torque were directly and significantly related to the ankle dorsiflexion passive-elastic stiffness and good predictors of stiffness in the last half of the passive ankle dorsiflexion stretch.

ABSTRACT Objective: To compare the plaque removal efficacy of an oscillating-rotating electric toothbrush with an orthodontic brush head versus a sonic toothbrush in adolescent patients with fixed orthodontic appliances. Materials and Methods: This was a randomized, examiner-blind, replicate single-use, two-treatment, four-period, crossover study with a washout period between visits of approximately 24 hours. Forty-four adolescent patients with fixed orthodontic appliances in both arches were randomized based on a computer-generated randomization schedule to one of four toothbrush treatment sequences. The primary outcome was plaque score change from baseline, measured using digital plaque imaging analysis. Results: Baseline plaque levels for both brush treatments were high, covering more than 50% of the tooth area. Effective plaque removal was observed with both brush treatments (P < .001); however, the reduction in plaque with the oscillating-rotating toothbrush was statistically significantly greater (P = .017) compared with the sonic toothbrush. Conclusions: The study provides evidence for more effective plaque-removing efficacy of the oscillating-rotating toothbrush versus the sonic toothbrush among orthodontic patients.

Background: Sedentary behavior is associated with musculoskeletal discomfort (MSD) and especially prevalent in office workers. Objective: This cross-sectional analysis examined postures and activities of office workers to determine whether there were associations between posture/activity levels, MSD, and cardiometabolic measures. Methods: Participants completed baseline questionnaires, wore an inertial measuring unit, blood pressure cuff, and heart rate monitor to quantify posture, physical activity, and cardiometabolic measures. The relationships among posture/activity, MSD, and cardiometabolic data were assessed using Pearson correlation coefficients. Results: There were weak to moderate negative correlations between steps per day, hours spent standing, and hours spent walking and MSD. Weak to moderate positive correlations existed between time spent sitting, transitions, and MSD, yet there were moderate correlations between the number of transitions and measures of heart rate. Conclusion: Future interventions should take into consideration comprehensive approaches to decrease sedentary time throughout the day and maximize worker health.

Purpose: This study was conducted to identify correlations between how much fever management information mothers obtained from the internet and their actual knowledge and practices of fever management. Methods: This was a descriptive survey of 172 mothers with children aged between 0 and 3 attending five daycare centers located in the city of Daegu. Descriptive statistics, the independent t-test or one-way analysis of variance, and Pearson correlation coefficients were used for data analysis.Results: In total, 75% of the mothers had searched the internet for information on fever management. The overwhelming majority (92.2%) used information from the internet to help manage fever in their children. Positive correlations were found between acquiring fever management information from the internet and fever management practices (r=.18, <i>p</i>=.038), and between mother’s knowledge and practices of fever management (r=.27, <i>p</i><.001). Conclusion: Based on the results of this study, to improve fever management practices, it is necessary to increase mothers’ knowledge. Therefore, resources should be developed to augment mothers’ knowledge of fever management through the internet.

Background: Abnormal foot posture and deformities are identified as important features in rheumatoid arthritis. There is still no consensus regarding the optimum technique(s) for quantifying these features; hence, a foot digitizer might be used as an objective measurement tool. We sought to assess the validity and reliability of the INFOOT digitizer. Methods: To investigate the validity of the INFOOT digitizer compared with clinical measurements, we calculated Pearson correlation coefficients. To investigate the reliability of the INFOOT digitizer, we calculated intraclass correlation coefficients, SEMs, smallest detectable differences, and smallest detectable difference percentages. Results: Most of the 38 parameters showed good intraclass correlation coefficients, with values greater than 0.9 for 30 parameters and greater than 0.8 for seven parameters. The left heel bone angle expressed a moderate correlation, with a value of 0.609. The SEM values varied between 0.31 and 3.51 mm for the length and width measures, between 0.74 and 5.58 mm for the height data, between 0.75 and 5.9 mm for the circumferences, and between 0.78° and 2.98° for the angles. The smallest detectable difference values ranged from 0.86 to 16.36 mm for length, width, height, and circumference measures and from 2.17° to 8.26° for the angle measures. For the validity of the INFOOT three-dimensional foot digitizer, Pearson correlation coefficients varied between 0.750 and 0.997. Conclusions: In this rheumatoid arthritis population, good validity was demonstrated compared with clinical measurements, and most of the obtained parameters proved to be reliable.

Using Data

The composition of the intestinal microbiota of 92 healthy Japanese men was measured following consumption of identical meals for 3 days; terminal restriction fragment length polymorphisms were then used to analyse the DNA content of their faeces. The obtained operational taxonomic units (OTUs) were further analysed using seven restriction enzymes: 516f-BslI and -HaeIII, 27f-MspI and -AluI, and 35f-HhaI, -MspI and -AluI. Subjects were classified by their body mass index (BMI) as lean (<18.5) or obese (>25.0). OTUs were then analysed using data mining software. Pearson correlation coefficients on data mining results indicated only a weak relationship between BMI and OTU diversity. Specific OTUs attributed to lean and obese subjects were further examined by data mining with six groups of enzymes and closely related accession numbers for lean and obese subjects were successfully narrowed down. 16S rRNA sequences showed Bacillus spp., Erysipelothrix spp. and Holdemania spp. to be present among 30 bacterial candidates related to the lean group. Fifteen candidates were classified Firmicutes, one was classified as Chloroflexi, and the others were not classified. 45 Microbacteriaceae, 11 uncultured Actinobacterium, and 3 other families were present among the 119 candidate OTUs related to obesity. We conclude that the presence of Firmicutes and Actinobacteria may be related to the BMI of the subject.

AbsractObjectivesTo evaluate the relationship between Emergency Physician (EP) productivity and patient satisfaction with Emergency Department (ED) care.MethodsThis retrospective observational study linked administrative and patient experience databases to measure correlations between the patient experience and EP productivity. The study was performed across three Calgary EDs (from June 2010 to July 2013). Patients>16 years old with completed Health Quality Council of Alberta (HQCA) ED Patient Experience Surveys were included. EP productivity was measured at the individual physician level and defined as the average number of patients seen per hour. The association between physician productivity and patient experience scores from six composite domains of the HQCA ED Patient Experience Survey were examined using Pearson correlation coefficients, linear regression modelling, and a path analysis.ResultsWe correlated 3,794 patient experience surveys with productivity data for 130 EPs. Very weak non-significant negative correlations existed between productivity and survey composites: “Staff Care and Communication” (r=-0.057, p=0.521), “Discharge Communication” (r=-0.144, p=0.102), and “Respect” (r=-0.027, p=0.760). Very weak, non-significant positive correlations existed between productivity and the composite domains: “Medication Communication” (r=0.003, p=0.974) and “Pain management” (r=0.020, p=0.824). A univariate general linear model yielded no statistically significant correlations between EP productivity and patient experience, and the path analysis failed to show a relationship between the variables.ConclusionWe found no correlation between EP productivity and the patient experience.

Abstract Multiparous, fall-calving beef cows [n = 48; 649 ± 80 (SD) kg BW; 5.3 ± 0.5 BCS] were individually-fed tall fescue-based hay (12.2% CP, 61.5% NDF) and supplemented to meet/exceed nutrient recommendations except Cu, Zn, and Mn. From approximately 90 d pre-calving to 11 d post-calving, cows received: no additional Cu, Zn, or Mn (CON); Cu, Zn, and Mn sulfates (ITM) or metal methionine hydroxy analogue chelates (CTM, MINTREX®, Novus International) supplying 133% NASEM recommendations; or Cu, Zn, and Mn sulfates and chelates supplying 100% recommendations (reduce and replace, RR). Treatment, sampling day, their interaction, and breeding group were fixed effects with cow as the experimental unit. Colostrum and milk Cu and Mn and plasma Mn were generally not detectable. Colostrum Zn was greater (P ≤ 0.03) in CTM and ITM than CON and RR. All treatments had greater (P < 0.001) colostrum Zn than d 35 milk, which was greater (P ≤ 0.03) than d 60. Treatment did not affect (P ≥ 0.19) cow or calf plasma Cu or Zn post-calving. Calf plasma Zn decreased (P ≤ 0.02) from 0 to 35 d of age. Calf plasma Cu increased (P < 0.01) from 0 to 35 d, then decreased (P = 0.01) from 35 to 60 d. Cow plasma Zn and Cu were greater (P ≤ 0.02) at lactation d 35 and 60 than 1 h post-calving. Pearson correlation coefficients were used to determine relationships among cow and calf mineral status. There were weak positive correlations (P ≤ 0.06) between calf plasma and milk Zn at d 35 and 60. Cow and calf plasma Zn immediately post-calving had a weak negative correlation (P = 0.04). These results indicate greater Zn concentration in beef cow colostrum than milk, and suggest calf circulating Zn is partially dependent on milk Zn concentration.

Purpose: The purpose of this study was to examine the correlations among meaning in life, social support, and posttraumatic growth and to identify the factors related to posttraumatic growth in pancreatic cancer patients.Methods: A total of 118 pancreatic cancer patients who received care in an outpatient clinic and inpatient units in an oncology center in Seoul were enrolled from February 2021 to March 2021. We collected data using self-report survey tools. Data were analyzed using descriptive statistics, Pearson correlation coefficients, and hierarchical multiple linear regression with SPSS/WIN 26.0Results: Meaning in life, social support, and posttraumatic growth had significant positive correlations with each other, and the correlation between posttraumatic growth and meaning in life was the highest (r=.63, p<.01). In the hierarchical multiple regression model of posttraumatic growth (adjusted R2=.48, p<.001), marital status (β=-.14, p=.04), meaning in life (β=.44, p<.001), and social support (β=.27, p=.001) were statistically significant.Conclusion: There is a need for nursing interventions that provide social support and promote the meaning in life to facilitate posttraumatic growth in pancreatic cancer patients.
