{"title":"Efficacy of Peroral Endoscopic Myotomy for Achalasia: Evaluation of Treatment Effect using Timed Barium Esophagography","authors":"Jae-Joon Chung, Eun-Suk Cho, Joo Hee Kim","doi":"10.59879/4ppre","DOIUrl":"https://doi.org/10.59879/4ppre","url":null,"abstract":"Peroral endoscopic myotomy (POEM) is one of the standard treatment modality for achalasia. This study was to evaluate the usefulness of timed barium esophagography (TBE) in the evaluation of treatment effect of POEM for achalasia. A total of 36 patients (M:F=22:14) underwent pre- and post-POEM TBE (3 groups according to lower esophageal sphincter (LES) caliber, A: < 5 mm, B: 5~8 mm, C: > 8 mm). On pre and post-POEM TBE, the rate of area changes of barium column and the changes of LES caliber were investigated. All data were statistically analyzed using the Kruskal-Wallis test or Mann-Whitney U test. The mean rate of area change of the barium column at 5 minutes between pre- and post-POEM TBE were -51.7%, -28.8% and -11.6% in group A (n=10), B (n=18), and C (n=8), respectively, statistically significant (p < 0.001). The rate difference of the barium column area changes between group A and group B only showed the statistical significance (p < 0.001). The mean increased caliber of LES after POEM was 5.5 mm, 2.9 mm, and 3.3 mm in group A, B, and C, respectively. Group A and bird’s beak type showed a statistically significant treatment effect (p < 0.001). In conclusion, TBE was useful in the evaluation of the treatment effect of POEM for achalasia and the narrowest LES group and bird’s beak esophageal type on TBE showed statistically significant treatment effects.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atrial fibrillation (AF) is the most common cause of inappropriate shocks. Therefore, to predict and treat AF may prevent inappropriate shocks and their hazardous potentials. This paper aimed to show that by measuring atrial refractoriness, we could predict the patients who may experience inappropriate implantable cardioverter-defibrillator shocks.n Material and methods: 186 consecutive patients who underwent initial ICD implantation underwent coronary angiography and also underwent electrophysiologic (EP) study before the ICD implantation. nResults: Of 169 patients who could be followed, 34 received (20%) at least 1 inappropriate shocks during the mean follow-up of 30 months. Majority of these shocks were due to AF (68%). Atrial effective refactory periods (AERPs) and AERP dispersion were the most significant predictors for these inappropriate shocks. nConclusion: We found that simple EP study parameters measuring atrial refractoriness may define the patients carrying higher risk for future inappropriate shocks due to AF. In these patients, by either device programming or pharmocological treatments or ablation procedures, we could prevent inappropriate shocks and their hazardous results.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three methods are depended on the production of yellow ion-pair complexes between the investigated drug and bromophenol blue (BPB), bromthymol blue (BTB), and bromocresol purple (BCP) as dyes in a universal buffer of pH range (2.0- 4.0). The chloroform was used for formed complexes extraction and measured at 421 nm, 414 nm, and 409 nm, respectively for the three systems. The best conditions of the reactions were tested and optimized. Beer’s law was obeyed in the concentration ranges 2.0 – 18.0 µg mL-1 with molar absorptivity of 4.4 × 104 , 6.4 × 104 and 6.9 × 104 L mol-1cm-1, for the BPB, BTB and BCP methods, respectively. Sandell’s sensitivity, correlation coefficient, quantification and detection limits are also studied. The investigated methods have been achieved successfully for the determination of the drug in pure form and in pharmaceutical formulations. Interference between common pharmaceutical excipients and additives was disappeared. Statistical comparison of the results with those observed by the HPLC method exhibits excellent agreement and shows no significant difference in terms of accuracy and precision.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71244267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Healthy dietary patterns were defined as diets that are high in fruits, vegetables and non-fat dairy (low in saturated and trans fats). The aims of this study were to determine the fatty acid (FA) profile of meat (poultry, pork, lamb and beef) and the calculated atherogenic index (AI) and thrombogenic index (TI). Poultry, pork and lamb contained more monounsaturated fatty acids (MUFAs) than saturated fatty acids (SFAs). Linear discriminant analysis (LDA) demonstrated that the first discriminant explained 56.11% of the total variance and the second discriminant explained 23.85% of the total variance. The established p value of Wilks' test was p < 0.0001. By canonical correlation, the first and the second discriminant functions in the LDA were established as 0.995 and 0.995, respectively. AI and TI values of less than 0.5 and 1.0, respectively, were previously advised. The obtained AI values in poultry (0.37-0.45) were lower than those in pork (0.50-0.53), lamb (0.54) and beef (0.93) meats.

Thus, digital technology innovation forms the foundation of digital innovation. Increasingly, firms, especially those in manufacturing, are recognizing the crucial role of digital technology innovation in shaping their intangible value. In order to determine whether digital technology innovation can enhance firm value and the specific mechanism involved, this study draws on patent data (the fields of digital technology are defined based on IPC) and annual report data of listed manufacturing firms in China to reveal the specific relationship between digital technology innovation and the enhancement of firm value. We find that that digital technology innovation can make a significant contribution to firm value; more important, the relationships between digital technology innovation and lowering costs, upgrading efficiency can be characterized as an inverted U-shaped pattern and a Ushaped pattern, respectively. These results hold after the several robustness checks. Additional analyses show that these relationships differ significantly across types of state ownership, firm size, and location feature. Finally, our mechanism analysis suggests that lowering costs and upgrading efficiency driven by digital technology innovation is a key component of the value-enhancing effect.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135104978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The classification speed is slow due to the large amount of processing data in the classification process. A three-stage random forest based on a fuzzy matrix method is proposed in this paper to improve the accuracy and the classification speed of low frequency oscillation early warning in power system. Firstly, the fuzzy matrix comprehensive evaluation is carried out by PMU data, and the evaluation score S will be obtained to determine whether low-frequency oscillation occurs and makes a quick warning. Then, the data is processed by Synchronous Wavelet Transform (SWT), and the damping ratio and attenuation factor of the data are obtained. Furthermore, Random Forest 2(RF 2) and RF 3 are used to judge the type of low frequency oscillation.

Method: 127 participants with a mean age of 66.82�16.39 (min=66, max=83) were included in the study. At the beginning of the study, the recordings of the Videofluoroscopy Swallow Study / Modified barium swallow study were scanned and examined, and those with the same dysphagia severity finding who had problems in swallowing safety and efficiency were determined. Patients were randomly assigned to either a short-term intervention group (six weeks; n=62, 48.8%,) or a long-term intervention group (12 weeks; n=65, 51.2%). During Videofluoroscopy, patients were scored with the Penetration-Aspiration Scale by giving food in different consistencies (thin liquid, honey, nectar, pudding, solid consistency) according to the International Dysphagia Dietary Standardization Initiative protocol. Functional Oral Intake Scale and Turkish Eating Assessment Tool results were compared between the groups receiving long-term and short-term swallowing therapy. An exercise-based individual swallowing therapy program was applied to both groups. Results: Penetration aspiration score was higher in the short-term therapy group than in the long-term group. There was a significant difference between the post-therapy penetration aspiration scores of individuals who received long-term and short-term therapy (p<0.001). Pharyngeal phase abnormalities were detected in 81 patients (88.4%), and laryngeal penetration/aspiration status was found in 78 patients (85.3%). Both variables were found to be significantly higher in the short-term group (p:0.015; p:0.014). Turkish eating assessment tool scores were found to be 21.51�3.84 in the long-term group after therapy (p<0.05). Silent aspiration of thin liquid and nectar consistency was experienced in 69% of the patients before the therapy.

Pedestrians are considered as the most vulnerable road user group. Moreover, involvement of young people in road crashes is among the most alarming aspects for most of the countries in the world. This research employs a survey questionnaire to determine the preferences related to use of pedestrian bridge, before and after its rehabilitation. The analysis of the questionnaire included statistical tests, logistic regression and CART model. It was found that the physical condition of the bridge has the most profound effect on the hazard perception of young pedestrians, in spite of the presence of other factors related to safety and security. Most of the pedestrians preferred using the pedestrian bridge during the afternoon, irrespective of the condition of the bridge. It was also found that the before data had a higher impact of gender, with more female respondents showing safety concerns and using the pedestrian bridge. The after data showed a more uniform distribution among genders. Although, the CART model showed significant impact of gender on the perception related to beggars, being the most important risk hazard. It is recommended for future studies to be performed on a larger dataset, include more variables and employ CART technique for modeling.","PeriodicalId":49454,"journal":{"name":"Sylwan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135801176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
