Single Suture

Background: Epitendinous sutures not only join the 2 severed tendon edges but also supply strength and support to the repair. Multiple techniques have been described, but none of them include another thread of suture. This could potentially increase the strength of the repair without affecting gliding. Methods: Caprine tendons were harvested, transected, and sutured with 6-0 Prolene. Four groups were created: single thread running (SR), single thread locking (SL), double thread running (DR), and double thread locking (DL). An Instron 5542 was used to pull the repaired tendons apart, and the energy at the break was calculated (gf/mm). For gliding resistance, we harvested a human A2 pulley. A pre- and postrepair value was obtained, and a ratio was elaborated. A single-factor analysis of variance and independent sample t tests were performed. Results: The SR group had a mean energy at break of 9339.71 ± 1630.212 gf/mm; the SL group, 9629.96 ± 1476.45 gf/mm; and the DR group, 9600.221 ± 976.087 gf/mm, with no statistical significance. The DL group was significantly higher at 14 740.664 ± 2596.586 gf/mm ( P < .05). When comparing SR with DL for gliding, SR had less than half of the resistance than DL (0.018 ± 0.004 and 0.049 ± 0.015 N/mm, respectively), with statistical significance ( P < .05). Conclusion: Using a single suture thread for running epitendinous repair is no different than locking with a single thread or using an extra thread in a running fashion. Performing a double suture thread with a locking technique is significantly stronger than the previously mentioned repairs, with the disadvantage of more resistance at the pulley.

Germination od three non GMO soybean cultivars: Abelina, SG Anser and Merlin was examined in a laboratory study as affected by pH level: 5.0; 5.5; 6.0; 6.5 and 7.0. The soybean seeds came from a field experiment carried out in 2017–2018. Analysis of germination capacity was based on two-factor analysis of variance in a completely randomized setting. Among the tested cultivar Abelina had the highest germination capacity. An application of pH from 6.0 to 6.5 contributed the most germinated seeds: 90.0 and 92.0%, respectively. The highest number of abnormally germinating seeds was observed in cultivar SG Anser and when the pH of the soil was 5.0 to 5.5. The numer of non-germinating seeds was higher in 2018 than 2017 and only in the cultivar Abelina did not differ significantly between years.

ABSTRACTBackground:As more older persons opt to age in place, there is a growing trend to hire migrant workers as live-in caregivers to care for them. This raises the need to examine the quality of care they receive within this unique care setting. The objective of this pilot study was to establish the components of quality of care as provided by migrant live-in caregivers.Methods:We interviewed a convenience sample of older persons cared for by migrant live-in caregivers and their relatives. When relatives reported that older persons could not be interviewed due to advanced dementia, only relatives were interviewed. Overall, 72 older persons and 117 relatives were interviewed. We used the Quality of Care Questionnaire (QuCQ) developed for this study to examine the main components of quality of care in this population.Results:Factor analysis using older persons’ data revealed two factors. In the first factor, “caretaking,” items concerning provision of prompt care exhibited the highest loadings. Items measuring interpersonal aspects of the care dynamic had the highest loadings in the second factor, thus labeled “relationship.” The factor analysis based on relatives’ data yielded similarities and differences with the one based on older persons’ data. Yet, there were significant correlations between relative and older persons’ responses when using the older persons’ factor structure.Conclusions:According to older persons and relatives, quality of care depends on the extent to which older persons’ care-related needs, as well as social ones, are addressed. Appropriate evaluation of quality of care in the live-in setting is important for its improvement.

Chapter 8 tests observable implications of the book’s theory on constituency service’s supply, using the field experiment introduced in Chapter 3 to assess politicians’ motivations to respond to petitions. It shows that indicators of a personal vote—that the petitioner has voted for the politician in the past—can have a small positive effect on the quality of a politician’s response, if not the baseline response rate. This chapter also investigates whether information on local blocking affects politicians’ willingness to respond. It shows that, in states with a long history of local elections, politicians interpret information about a failure to receive assistance locally as an indicator of local partisan blocking and, combined with information on electoral history, an indication that the petitioner is a supporter or persuadable voter. Consistent with qualitative evidence from politician shadowing, this experimental evidence substantiates the argument that politicians use constituency service to reach potential supporters.

PURPOSE To assess whether prechemotherapy health-related quality-of-life (HQL) variables are associated with postchemotherapy nausea and vomiting (PCNV), and to determine their relationship to patient and treatment variables. PATIENTS AND METHODS Eight hundred thirty-two chemotherapy-naive patients scheduled to receive antiemetic regimens containing a 5-hydroxytryptamine (5-HT3) antagonist with or without dexamethasone for moderately or highly emetogenic chemotherapy were enrolled. HQL was measured by the self-report European Organization for Research and Treatment of Cancer (EORTC) Care Quality of Life Questionnaire (QLQ-C30) within 7 days before chemotherapy. Prechemotherapy HQL scores, as well as other patient, disease, and treatment variables were compared in the groups of patients who had PCNV and those who did not have PCNV. All variables were assessed initially in a univariate analysis and then together in a multivariate analysis using step-wise logistic regression. The final model generated by the multivariate analyses was used in a risk factor analysis to predict PCNV. RESULTS Univariate analyses identified 10 HQL variables and five patient and treatment characteristics that were associated with PCNV. In the multivariate analysis, the variables remaining in the final model included low social functioning, prechemotherapy nausea, female gender, highly emetogenic chemotherapy, and the lack of maintenance antiemetics (5-HT3 antagonists with or without dexamethasone) after chemotherapy. A history of low alcohol use was also associated with PCV, whereas increased fatigue and lower performance status were associated with PCN. In the risk factor analysis, the incidence of PCV increased from 20% in those having no risk factors to 76% in those having any four of the six risk factors. CONCLUSION Several pretreatment HQL, patient, and treatment characteristics are associated with the occurrence of PCNV. Patients about to receive moderately or highly emetogenic chemotherapy should be screened for these factors and additional measures, such as behavior modification and modification of antiemetic therapy, should be considered in attempts to improve the control of PCNV.

Aims: This study evaluated the effect of magnification on the quality of preclinical class I cavity preparations according to operator’s experience. Methodology: This was an experimental laboratory study. The response variable was the quality of Class I cavity preparations evaluated by the Class I Cavity Preparation Assessment - COCA. Class I cavity preparations were performed in all artificial first molars under four conditions: unaided visualization, using a simple loupe, using a Galilean loupe, and using a Keplerian loupe (N=640). The two-factor analysis of variance was performed (α=0.05). Results: No interactions between operator’s experience and magnification device were found (p>0.05). Although, higher quality scores were given to cavity preparations in tooth #36 using the Galilean loupe compared to naked eye (p<0.01). The more experienced operator received higher quality scores for tooth #46 regardless of the magnification system used (µexperienced=7.0±2.3 and µinexperienced=5.4±2.4). Conclusion: The use of magnification devices did not influence the quality of class I cavity preparations performed on tooth #16, 26, 46. Galilean loupe was associated with improved quality of the cavity preparation performed on tooth #36, and the operator’s experience influenced the quality of the preparation on tooth #46.
