Abstract Background: General anesthesia can affect intestinal function, but there is no objective and effective indicator to evaluate the inhibition and recovery of intestinal function. The main objective of this study is to assess whether bowel sounds (BSs) change before and after general anesthesia, then it can be explained that the BS can be an effective indicator of intestinal function. Methods: We randomly selected 26 inpatients and collected three sets of 5-minute continuous BSs before operation (Pre-op), after operation (Pro-op) and three hours after operation(3h-Pro-op) separately for each patient. The data were de-noised with adaptive filtering and wavelet threshold denoising, and processed with fractal dimension to identify the effective bowel sounds (EBSs). Then the linear and nonlinear characteristic values (CVs) of each EBS were extracted and paired t -test and rank-sum test were used to evaluate the changes of the BSs after general anesthesia. Results: For the difference between Pre-op and Pro-op, as well as between Pro-op and 3h-Pro-op, there are statistical differences ( p <0.05). Specifically, the linear CVs that can reflect the occurrence frequency, overall energy and overall duration of EBSs and the nonlinear CVs that can reflect the dispersion degree of stability and complexity of EBSs were statistically significant. However, there is no statistical difference in the CVs reflecting the energy and duration, as well as the stability and complexity of locally EBSs ( p >0.05). Also, there is no statistically significant difference between all the characteristic values between Pre-op and 3h-Pro-op ( p >0.05). Conclusion: The BSs change after general anesthesia. Furthermore, the BSs are weakened after general anesthesia and recovered to the state before general anesthesia three hours later. Therefore, the BS can be an indicator of intestinal function under general anesthesia, so as to provide guidance for postoperative feeding , which is of great clinical significance.

Abstract Background: General anesthesia can affect intestinal function, but there is no objective, practical and effective indicator to evaluate the inhibition and recovery of intestinal function. The main objectives of this study were to assess whether bowel sounds (BSs) changed before, immediately after and 3 hours after general anesthesia, and whether these changes in BSs are an effective indicator of intestinal function and an accurate guide for post-operative feeding. Methods: We randomly selected 26 inpatients and collected three sets of 5-minute continuous BS data before the operation (Pre-op), immediately after the operation (Pro-op) and three hours after the operation (3h-Pro-op) for each patient. Then the linear and nonlinear characteristic values (CVs) of each EBS were extracted and paired t -tests and rank-sum tests were used to evaluate the changes in the BSs. Results: The differences in CVs, between Pre-op and Pro-op, as well as between Pro-op and 3h-Pro-op, were statistically significant ( p <0.05). However, there is no statistically significant differences between all the CVs between Pre-op and 3h-Pro-op ( p >0.05). Conclusion: BSs changes before and after general anesthesia. Furthermore, the BSs are weakened due to general anesthesia and recover to the pre-op state three hours later. Therefore, the BSs can be an indicator of intestinal function under general anesthesia, so as to provide guidance for postoperative feeding , which is of considerable clinical significance.

Signal Intensities

The effects of acute pancreatitis on MR imaging signal intensities (SIs) were determined in an experimental study at 1.0 T. Oedematous pancreatitis was induced in 9 piglets and haemorrhagic pancreatitis in 11 piglets. Each animal served as its own control for MR imaging before and after induction of pancreatitis. T1-weighted spin echo (450/15 ms) and dynamic turbo FLASH (flip angle 8°) sequences were used without contrast medium in testing the stability of the SI measurements. There was no significant difference in the SI-versus-time curves of the pancreas in piglets with oedematous and haemorrhagic pancreatitis. However, the difference in mean SIs between healthy and diseased piglets was significant. Thus, although non-contrast MR may be useful in the diagnosis of acute pancreatitis, it does not distinguish between oedematous and haemorrhagic pancreatitis.

The purpose of this study is to explore the stability and interaction between parental pressure and social research report, as well as the role of employment status and family income levels in this process. This study used a special study on Korean children (PSKC) 2–4 waves. Use t-test, correlation and autoregressive cross-delay modeling to analyze the data. The main findings of this study are: First, over time, parental pressure and mother’s social research report are consistent. Secondly, the pressure of motherhood and childcare has an obvious lagging effect on upbringing, and vice versa. Third, there is no significant difference between working mothers and non-working mothers in terms of the stability of working parents' pressure, social research report and social research report for children's pressure channels. However, parental pressure can only predict the social research report of working mothers. Fourth, there is no significant difference between the stability and interaction of these two structures in household income levels. In short, the results show that, over time, parental pressure is consistent with mother’s social research report. The results also show that there is a significant cross-lag effect between the mothers’ perceptions of mutual pressure analysis. In the process from parental pressure to social research report, I found the difference between working and non-working mothers. The advantage of this study is that the expected longitudinal design was adopted during infancy and the priority between the two structures can be considered. The results of this study can be used as a source of intervention plans to help parents withstand severe parenting pressure and lack of social research report.

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

Background:For patients whose centric relation (CR) has not been considered at the start and during treatment, the task of achieving an occlusal scheme that works together with the temporomandibular joint, the muscles, and the structures of the stomatognathic apparatus becomes a major concern.Objective:This study aims to describe a reproducible, predictable and to date unreported procedure of selective grinding guided by an occlusal splint and to analyze condylar position (CP) based on the skeletal pattern.Methods:A total of 72 symptomatic patients (38 females and 34 males) were classified into three groups: hyperdivergent, intermediate and hypodivergent. CP was quantified by mounted casts on a measures condyle displacement (MCD) device. Helkimo index was also performed in order to assess the severity of the temporomandibular joint (TMJ) disorders attending to clinical dysfunction, occlusal state and anamnestic dysfunction. Once the stability had been obtained, the splint was progressively reduced until the maximum intercuspation (MIC) was achieved.Results:The vertical displacement was found to be significantly different between the hyperdivergent and other two groups (p<0.01). Comparisons of MCD analysis before and after the selective grinding procedure identified a statistically significant difference in the horizontal and vertical CP (p<0.01) between the different groups whereas the Helkimo Index showed a clear improvement of TMJ disorders.Conclusion:All facial types, specially the hyperdivergent face type, showed a reduction in condylar displacement (CD) and less craniomandibular symptoms using this procedure, making it an excellent technique for clinicians.

In this paper, a mathematical model with time-delay-related parameters and media coverage to describe the diffusion process of new products is proposed, in which the time-delay-related parameters denote the stage in which potential customers decide whether to adopt a new product. Then, the stability and the Hopf bifurcation of the proposed model are analyzed in detail. The center manifold theorem and the normal form theory are used to investigate the stability of the bifurcating periodic solution. Moreover, a numerical simulation is conducted to investigate the difference between the model with delay-dependent parameters and that with delay-independent parameters. The results show that there is significant difference between the two models.

Dental healthcare is very important since dental and oral hygiene should be maintained. Statistics showed that more than 80% of children in developed and developing countries suffer from dental disease. This study aimed to see the safety of OHIS (Oral Hygiene Index Simplified) in primary school students who got and did not get little dentist cadre training in Bangli Regency in 2019. The study was done in an experimental design: pre and post-test with control design, which was conducted in August-September 2019. The sample in this study is 366 students. The difference in OHIS scores before and after treatment in the control group and treatment group was carried out by the bivariate Mann Whitney U Test. The results of the study showed that before dental health training was conducted, there were 54.3% of primary school students in the treatment group with good OHIS score criteria, and after the training was carried out as many as 98.4% of the students in the treatment group had a good OHIS. Additionally, prior to the training, 57.5% of the control group had fair OHIS criteria score. Then, after the training was carried out, 73.7% of the control group had good OHIS score. Hence, the study concluded that there was a significant difference in the OHIS of primary school students who got little doctor training prior to and after the training. Also, there was a significant difference in the OHIS of the students who did not get such treatment before and after the training.
