BACKGROUND Percutaneous hepatobiliary drainage(PTCD)is an effective method for the treatment of biliary obstruction and other diseases,but postoperative complications are still one of the important problems faced by patients.Continuous nursing is a comprehensive nursing model that plays an important role in postoperative recovery.The purpose of this study was to investigate the effect of continuous nursing on the incidence of complications in patients after PTCD surgery through meta-analysis and to evaluate its efficacy and safety.AIM To evaluate the effect of extended nursing on the incidence of complications in discharged patients after percutaneous transhepatic biliary drainage(PTBD).METHODS Randomized controlled studies on PTBD postdischarge extended care were identified in the CNKI,Wanfang,VIP,CBM,PubMed,Cochrane Library,Embase,Web of Science,and other databases.The quality of the included studies was evaluated using the Joanna Briggs Institute of Australia literature quality evaluation tool,and a meta-analysis of the included studies was performed with RevMan 5.4 software.RESULTS Finally,9 studies were included,with a total sample size of 854 patients(425 patients in the control group and 429 patients in the intervention group).Meta-analysis revealed that extended care effectively reduced biliary tract infection(RR:0.42,95%CI:0.30-0.57),puncture wound infection(RR:0.19,95%CI:0.06-0.65),catheter protrusion or displacement in discharged patients after PTBD(RR:0.31,95%CI:0.18-0.54),catheter blockage(RR:0.23,95%CI:0.13-0.42),skin infection around the drainage tube(RR:0.30,95%CI:0.12-0.77),and catheter-related readmissions(RR:0.34,95%CI:0.18-0.65)(P<0.05).CONCLUSION Compared with conventional discharge care,extended care can effectively reduce the occurrence of complications such as biliary tract infection,puncture wound infection,catheter prolapse or displacement,catheter blockage,skin infection around the drainage tube,and catheter-related readmission in discharged patients after PTBD. 展开更多

Introduction: International migration has always existed, primarily as a means to find economic opportunity. Recently, the number of health care professionals seeking to work outside Albania is growing rapidly. In 2021 alone, 1073 nurses left Albania. The departure of health care professionals is reflected in education where it can be observed that a good part of the students who finished the bachelor’s level program did not enroll to continue the second level of study in the master’s. The student’s decision not to continue further levels of education has brought consequences from programs shutting down due to lack of students and forcing the university to spread out the few remaining students to other programs. Objective: The purpose of the study was to explore the opinions of Midwifery Students studying at the Bachelor level, regarding their professional future and continuing education. Methodology: This is a cross-sectional study. In this study are included the students of the bachelor level of education. Student participating are studying Midwifery in the 2022-2023 academic year, at the Faculty of Technical Medical Sciences at the University of Medicine, Albania. Results: The students on average believe they can find a job as a midwife. The career is relatively safe and the profession of midwifery will ensure economic well-being for them. Most of the students hope to emigrate and develop their professional career outside of Albania. This was a surprise given that most frequent answers given by the students for not continuing their Master’s level education was the fact that the program was not accredited, their Bachelor’s diploma was also not accredited and so not recognized by other countries, the cost of continuing their studies was too high and their desire for a better economic and social status which they cannot get in Albania. The majority of students participating in the study identified emigration as the main way they plan to further their studies. Conclusions and Recommendations: Although the students had willingly chosen to continue the midwifery diploma, as they thought it would provide them with a proper future, this dignified professional future was seen as unattainable in Albania so they are seeking it out in more developed countries. A significant number of health professionals prefer to continue their second cycle studies in another country. The professional security within their home country does not satisfy the students. As the market demand for nurses around the globe escalates, the changes and consequences associated with nurse migration are increasingly in need of policy solutions that will address the needs of all parties involved. . 展开更多

Branched continued fractions are one of the multidimensional generalization of the continued fractions. Branched continued fractions with not equivalent variables are an analog of the regular C-fractions for multiple power series. We consider 1-periodic branched continued fraction of the special form which is an analog fraction with not equivalent variables if the values of that variables are fixed. We establish an analog of the parabola theorem for that fraction and estimate truncation error bounds for that fractions at some restrictions. We also propose to use weight coefficients for obtaining different parabolic regions for the same fraction without any additional restriction for first element. 展开更多

A famous theorem of Szemer'edi asserts that any subset of integers with posi- tive upper density contains arbitrarily arithmetic progressions. Let Fq be a finite field with q elements and Fq((X^-1)) be the power field of formal series with coefficients lying in Fq. In this paper, we concern with the analogous Szemeredi problem for continued fractions of Laurent series: we will show that the set of points x ∈ Fq((X-1)) of whose sequence of degrees of partial quotients is strictly increasing and contain arbitrarily long arithmetic progressions is of Hausdorff dimension 1/2. 展开更多

These methods mainly include Continuous Wavelet and Wavelet Packet transforms. The main advantage of the application of these Wavelets is their capacity to analyze the signal position in different occasions and places. However, in sites with high frequencies its resolution becomes much more difficult. Wavelet packet transform is a more advanced form of continuous wavelets and can make a perfect level by level resolution for each signal. Although very few studies have been done in the field. In order to do this, in the present study, f^st there was an attempt to do a modal analysis on the structure by the ANSYS finite elements software, then using MATLAB, the wavelet was investigated through a continuous wavelet analysis. Finally the results were displayed in 2-D location-coefficient figures. In the second form, transient-dynamic analysis was done on the structure to find out the characteristics of the damage and the wavelet packet energy rate index was suggested. The results indicate that suggested index in the second form is both practical and applicable, and also this index is sensitive to the intensity of the damage. 展开更多
