BACKGROUND Endoscopic retrograde cholangiopancreatography(ERCP)is an invasive endoscopic procedure used mainly to treat hepato-pancreato-biliary(HPB)diseases.The need for ERCP has increased with the rising number of HPB diseases over the past decade.Thus,due to increased demand,ERCP is performed at more centers.Currently,it is performed by general surgeons,gastroenterology and invasive radiology specialists in the United States and Europe as recommended by the British Society of Gastroenterology(BSG).AIM To present the results of ERCP procedures from fourteen surgical centers in Türkiye.METHODS Fourteen surgical centers performing ERCP were included in the present study.The age,gender,ERCP indication,success status,post-ERCP complications,ERCP reports and the files of 66993 patients who underwent ERCP were collected from the participating centers.The results are discussed according to the targets declared by the BSG,which are volume load per annum,proportion of successful cannulation(>85%),bile duct clearance rate(>75%),stenting rate for strictures(>80%)and complications(<6%).RESULTS A total of 66993 ERCP procedures were performed in the centers included in the study up to August 2024.29250(43.6%)of the procedures were performed urgently,especially for suppurative cholangitis,biliary tract injuries,etc.The remaining 37743(56.4%)cases were performed electively.50.2%of the patients were female and 49.8%were male.The average ages were 56.5 years for women and 55.9 years for men.General anesthesia was used in 84.1%of the patients while sedation was used in 15.9%.The indications were bile duct stone(78.7%),pancreatic tumor(3.9%),papillary tumor(3.3%),cholangiocarcinoma(2.6%),Oddi sphincter dysfunction(2.4%),bile leakage after cholecystectomy(2%),bile leakage after hydatid cyst surgery(1.9%),biliary stricture(1.7%),and other diseases(3.1%).Hyperamylasemia and post-ERCP pancreatitis were the most common complications as observed in 8.1%of the patients.They were usually self-limited and responded to supportive measures.The frequency of the other complications was also consistent with the literature.CONCLUSION There is a huge shortage of ERCP endoscopists worldwide due to insufficient ERCP training and centers especially in developing and underdeveloped countries.As patients requiring ERCP usually present to surgical practitioners,the incorporation of surgeons into this training program is an effective and reliable solution.The BSG recommends the incorporation of surgeons and radiologists in addition to gastroenterology specialists.This study is the first to present the results of ERCP procedures from fourteen surgical centers throughout Türkiye.The results suggest that the surgical centers included were able to achieve the targets set by the BSG.This study demonstrated that the surgical ERCP units in the present work have reached satisfactory results and provided a reliable and successful ERCP service.There are currently no issues regarding the validity and appropriateness of the surgeons performing ERCP.Therefore,ERCP training should be encouraged in surgeons and more surgical ERCP centers should be provided. 展开更多

BACKGROUND This research demonstrates that nurses feel pain because the pandemic process has separated them from their family and children.AIM To examine the family relationship situation of nurses in the coronavirus disease 2019(COVID-19)pandemic.METHODS The research adopted a descriptive qualitative design.Participants were selected by the snowball method.An individual in-depth interview technique was used while the participants were away.In-depth interviews were made with a total of 27 nurses.Nine of these nurses were excluded from the study due to communication problems and device problems during the interview.RESULTS This research showed that nurses suffered from family relationship breakdown and insufficiency in intrafamilial coping.The nurses stayed away from their families due to overtime and fear of COVID-19.They cannot meet the needs of their children and spouses for whom they are responsible,and they cannot spare time for them.They were living a tiring life with great responsibility and faced with mental problems such as burnout syndrome and depression.This study was conducted in three cities with a high number of COVID-19 cases in Turkey.We investigated three themes:Breakdown in continuity of intrafamilial relationship,ineffectiveness in role performance,and ineffective individual coping.CONCLUSION The nurses suffer from conditions such as change in parent-infant/child relation and insufficiency in intrafamilial process coping. 展开更多

Background:Bongardia chrysogonum(L.)Spach,also known as“Uruf-el-Deek”,has been used by rural communities for the treatment of various diseases and disorders,owing to its wide array of secondary metabolite compositions.Methods:The current study was conducted to determine the total polyphenolic content of Bongardia chrysogonum(L.)Spach as well as its potential free radical scavenging and metal-chelating antioxidant capacities.Its leaves,stems,and tubers were separately extracted using ethanol,water,and chloroform;their antioxidant activities were analyzed using in vitro models,including DPPH,ABTS,FRAP,and CUPRAC assays.The total polyphenolic content of the extracts was spectrophotometrically measured.Results:The richest polyphenolic content of the extracts was yielded by tuber chloroform and leaf ethanol extraction(215.09±0.53 mg/g extract as gallic acid equivalent and 240.74±1.12 mg/g extract as quercetin equivalent,respectively).Almost all of the tested extracts exhibited remarkable antioxidant activities,with the highest antioxidant capacity observed in the leaf extracts.On the other hand,the tuber ethanol extract demonstrated the weakest DPPH radical scavenging activity(%inhibition=49.75±0.38,P<0.01),while the tuber chloroform extract showed the weakest ABTS radical scavenging activity(%inhibition=62.61±0.06,P<0.05).These were closely followed by the tuber water extract(%inhibition=63.28±0.65,P<0.01).In terms of their FRAP and CUPRAC assays,the leaf ethanol extract was determined as the best one,with absorbance values of 3.64±0.01 and 2.22±0.01(P<0.01),respectively.Conclusion:Bongardia chrysogonum(L.)Spach possesses rich polyphenolic content and strong antioxidant activities.Thus,it could be a valuable source for the pharmaceutical industry in the prevention and treatment of diseases associated with oxidative stress. 展开更多

Recently,fuzzy multi-sets have come to the forefront of scientists’interest and have been used in algebraic structures such asmulti-groups,multirings,anti-fuzzy multigroup and(α,γ)-anti-fuzzy subgroups.In this paper,we first summarize the knowledge about the algebraic structure of fuzzy multi-sets such as(α,γ)-anti-multi-fuzzy subgroups.In a way,the notion of anti-fuzzy multigroup is an application of anti-fuzzy multi sets to the theory of group.The concept of anti-fuzzy multigroup is a complement of an algebraic structure of a fuzzy multi set that generalizes both the theories of classical group and fuzzy group.The aim of this paper is to highlight the connection between fuzzy multi-sets and algebraic structures from an anti-fuzzification point of view.Therefore,in this paper,we define(α,γ)-antimulti-fuzzy subgroups,(α,γ)-anti-multi-fuzzy normal subgroups,(α,γ)-antimulti-fuzzy homomorphism on(α,γ)-anti-multi-fuzzy subgroups and these been explicated some algebraic structures.Then,we introduce the concept(α,γ)-anti-multi-fuzzy subgroups and(α,γ)-anti-multi-fuzzy normal subgroups and of their properties.This new concept of homomorphism as a bridge among set theory,fuzzy set theory,anti-fuzzy multi sets theory and group theory and also shows the effect of anti-fuzzy multi sets on a group structure.Certain results that discuss the(α,γ)cuts of anti-fuzzy multigroup are explored. 展开更多

Corruption which means the use of public power for private interests is one of the most important problems either in less developed and developing countries or developed countries. Especially in less developed and developing countries, corruption is a serious obstacle in front of economic development. Corruption is raised from deficiency in democracy, deficient judgement, unfair elections and dependent media sector includes bribery, embezzlement, forgery, fraud, favouritism, nepotism and illegal beneficial use of public authority. The aim of the paper is to determine the causal relationship between corruption and basic macro-economic indicators. For this purpose, in this study, the basic mic indications such as import, export, budget deficit, manufacturer price index are taken into account as variables to examine their relation with corruption. By getting use of the data obtained from CPI index, the relation between the variables is examined using the T-Test. Furthermore, to determine the causality among all the variables, correllation analysis is applied to present causal relations between the corruption and macro-economic variables. The findings concluded that there is a significant correlation among corruption, manufacturer price index and export-import. However, there is no significant correlation with budget deficit. 展开更多

The Southeastern Anatolia Project (GAP) region located in southeastern of Anatolia has all of pistachio trees. In other words, pistachio trees have grown only in GAP region. Provinces of ~anliurfa, Gaziantep and Adiyaman are in the GAP region. In this study, we have investigated problems of pistachio farmers in these cities. So, we applied survey to pistachio farmers. Then we analyzed data which we had from the surveys with SPSS. As a result, the farmers have mainly got input problems, marketing problems, processing problems, keeping problems, financial problems, labor problems and managerial problems. As a solution, pistachio farmers must set up cooperatives which help finding inputs, markets, loan, labor, manager them and come up with their problems. Government has to support pistachio farmers and price of pistachio yield, pistachio farmers must have training programs about theirs works. Finally, pistachio nuts of stock market must be surely founded. 展开更多

Regardless of the industry in which a company operates,evaluating corporate performance is one of the most critical and vital processes;the most essential and prominent performance evaluation is related to financial performance.Appropriate performance analysis is complex and critical for decision-makers in different financial performance factors;thus,a methodological framework is needed to solve such complex decision problems.Therefore,this research aims to rank the companies included in the sustainability index(excluding banks)in Turkey by considering their financial performance.The criteria weights were determined using the full consistency method(FUCOM)by considering the evaluations of four experts.The firms were ranked using nine multi-criteria decision-making methods.The consensus among the nine rankings was ensured with the Copeland technique.The decision matrix includes financial ratios and the stock market performance of the firms;100,000 FUCOM weights were created with random evaluations to validate the results.The results indicate that the most crucial criterion is the current ratio by considering expert evaluations.Weight simulation indicates that alternative 16(alternative 21)is superior(inferior)to the other alternatives,even though the weights are determined with random evaluations.Ranking with expert evaluations is similar to the mean of the weight simulation results.The results demonstrate that the proposed framework can be performed as a basis for financial performance ranking. 展开更多
