Object ive To summar ize recent advance in the appl icat ion and research of ar t i f icial chordae tendineae. Methods The cl inical and experimental research l iterature was extensively reviewed and analyzed. Results The follow-up results showed that artificial chordae tendineae replacement was superior to other operation methods in valve repair. But, it was compl icated and difficult-to-learn. In recent years with the development of many surgical skills and new techniques, good cl inical results were achieved. Conclusion With the development of surgical equi pment, chordae material, and implanting skills, artificial chordae tendineae implanting will be easier and the scope of appl ication will be larger.
Healthcare-associated infection management has advanced rapidly in recent years. With the development of more standards and guidelines, infection control measures become more standardized and evidence-based. Evidence-based measures are increasingly applied in infection control, which promote more studies on the prevention and control of healthcare-associated infections. Furthermore, more new ideas of infection control have emerged, with old ones being challenged. The hand hygiene reform, multidrug-resistant organisms, and surgical site infections become the hot topics in recent years. In addition, whole-genome sequencing also provides more bases for understanding pathogen transmission in hospitals. Based on the high-quality studies published in recent years, this opinion review discusses these hot topics in the prevention and control of healthcare-associated infections.
ObjectiveTo summarize the current research progress of three-dimensional (3D) printing technique for spinal implants manufacture. MethodsThe recent original literature concerning technology, materials, process, clinical applications, and development direction of 3D printing technique in spinal implants was reviewed and analyzed. ResultsAt present, 3D printing technologies used to manufacture spinal implants include selective laser sintering, selective laser melting, and electron beam melting. Titanium and its alloys are mainly used. 3D printing spinal implants manufactured by the above materials and technology have been successfully used in clinical. But the problems regarding safety, related complications, cost-benefit analysis, efficacy compared with traditional spinal implants, and the lack of relevant policies and regulations remain to be solved. Conclusion3D printing technique is able to provide individual and customized spinal implants for patients, which is helpful for the clinicians to perform operations much more accurately and safely. With the rapid development of 3D printing technology and new materials, more and more 3D printing spinal implants will be developed and used clinically.
Before transcatheter aortic valve replacement (TAVR), echocardiography is the first choice for preoperative screening of suitable patients, which can be used to observe the morphology of aortic valve, determine the cause of aortic stenosis, and evaluate the severity of aortic stenosis and other cardiac structure and function. During TAVR procedure, echocardiography is mainly used for real-time monitoring of complications and immediate postoperative evaluation. After TAVR, echocardiography can be used to evaluate the shape and function of the prosthesis valve and monitor long-term complications. This article reviews the research progress of echocardiography in TAVR for guiding clinical practice.
Objective To review the study progress of mesenchymal stem cells induced to differentiate intervertebral disc cells Methods The recent related literature was reviewed. The theorical and experimental studies were summarized. Results MSCs had the potential of multidirectional differentiation.International experimental studies indicated the potential of MSCs induced to differentiate intervertebral disc cells. Conclusion MSCs induced to differentiate intervertebral disc cells has the fine prospect.
Cancer is a disease that incidence rate, disability rate and mortality rate are high all over the world. It brings great physical and mental pain to patients. Cancer patients are in a life-threatening state of disease for a long time, which will produce fear of progression (FoP). FoP is a psychological state in which fear of disease may recur or progress. As early as the 1980s, foreign countries began the psychological research on the FoP of cancer patients. They found that this fear really exists in cancer patients and is affected by many factors. This paper reviews the concept of FoP and the related factors affecting FoP in cancer patients. The purpose is to provide reference for clinical early evaluation and reducing the FoP of cancer patients and formulating corresponding nursing measures.
Febrile seizure is one of the most common emergencies in children, accounting for about 30% of all types of children, and the most common among children aged 6 months to 5 years. At the same time, children in this age group are at the peak of growth and development, and the content of various trace elements in the body is prone to abnormalities. At present, there are few related studies on febrile seizure and trace elements in children. This paper summarizes the related studies on febrile seizure and trace elements in order to provide theoretical guidance for the prevention and treatment of febrile seizure
ObjectiveTo summarize the clinical research progress of surgical procedures for cubital tunnel syndrome. MethodsThe related literature on surgical procedures for cubital tunnel syndrome was summarized and analyzed. ResultsMultiple surgical procedures have been applied to treat cubital tunnel syndrome, including simple decompression, subcutaneous transposition, submuscular transposition, medial epicondylectomy, intramuscular transposition, and ulnar groove plasty. Each procedure has its own advantages and disadvantages. With the development of minimally invasive surgical technique, endoscope-assisted surgery has been gradually applied to treat cubital tunnel syndrome. ConclusionOptimal surgical procedure remains controversial and individualized treatment decision based on patient's clinical conditions is recommended.
Objective To review the progress in the diagnosis and treatment of chronic disorders of achilles tendon. Methods Recent l iterature concerning the diagnosis and treatment of chronic disorders of achilles tendon was revi ewed. Results Ultrasonography and MRI were commonly used for diagnoses, and MRI could provide extensive informationfor the choice of therapy protocol. Nonsurgical therapy was the mainstay of treatment for most patients with overuse syndromes, surgical techniques for patients due to no effect in the conservative treatment and with chronic rupture, the cl inical treatment project should be determined based on the cl inical evaluation. Conclusion The surgical indication of chronic disorders of achilles tendon remains controversial, the long-term results of each treatment method are unknown, the randomized prospective studies are still required.
Sarcopenia has the characteristics of high morbidity and mortality, which seriously affects the quality of life of patients. Continuity of care, as an emerging nursing model in recent years, aims to improve self-care abilities of patients and their families, which can effectively reduce the rate of rehospitalization, and improve the quality of life of patients. This article starts with psychological intervention, nutrition guidance, patient exercise and medication guidance, and explores the application of continuity of care in patients with end-stage renal disease complicated with sarcopenia, analyzes the application of continuity of care in patients with end-stage renal diseases, and describes the implementation content and form of continuity of care, aiming to help its further promotion in clinic.
