Background: Nursing practice has to contribute to evidence pointing out why there is a need for more nurse-designed randomized control trials (RCTs) focusing on evidence-based practice (EBP). How far this EBP has progressed in different health aspects is usually established by systematic reviews of RCTs. Nurse-led RCTs exist but no study has addressed the essentials of nursing care. Aim: The aim was therefore to determine the essentials of nurses’ interventions by means of nurse-led RCTs in somatic care focusing on the stated context, goals, content, strategies as well as the nurse’s role related to effectiveness. Methods: A systematic review was realized according to Cochrane review assumptions to identify, appraise and synthesize all empirical evidence meeting pre-specified eligibility criteria. The PRISMA statement guided the data extraction process (n = 55) from PubMed and CINAHL. Results: Of the RCTs in somatic care, 71% showed a positive effectiveness of nurse-led interventions, of which the nurse had a significant role with regard to being the main responsible in 67% of the studies. Also, 47% of the RCTs presented a theoretical standpoint related to the nurse-led interventions and most prominent were international evidence-based guidelines. Goals were found to have either a patient-centered or a professional-centered ambition. Strategies were based on patient-directed initiatives, nurse-patient-directed initiatives or nurse-directed initiatives, while contents were built upon either a patient-nurse interaction or a nursing management plan. Conclusions: This review underlines the necessity of a holistic view of a person, as nurse-led RCTs comprising a patient-centered ambition, patient-directed initiative and patient-nurse interaction plan showed beneficial nursing care effectiveness, particularly if theory-based. In a nurse-led RCT, a basic theoretical perspective is advantageous as well as to elucidate the role of the nurse in relation to the estimated effec

引用

Journal of Shanghai Jiaotong university(Science) 2007年第6期12卷 744-752页

作者：王赓 Kondak Konstantin Marek Musial 盛焕烨吕恬生 hommel Günter Dept. of Computer Sci. & Eng. Shanghai Jiaotong Univ. Dept. of Computer Sci. & Electronics Technische Univ. Eng. Training Center Shanghai Jiaotong Univ.

It is devoted to the development of an autonomous flight control system for small size unmanned helicopter based on dynamical model. At first, the mathematical model of a small size helicopter is described. After that simple but effective MTCV control algorithm was proposed. The whole flight control algorithm is composed of two parts: orientation controller based on the model for rotation dynamics and a robust position controller for a double integrator. The MTCV block is also used to achieve translation velocity control. To demonstrate the performance of the presented algorithm, simulation results and results achieved in real flight experiments were presented.

Registered Nurses’ Perceptions of Factors Contributing to Trust-Based Public Management

引用

Open Journal of Nursing 2020年第11期10卷 1126-1141页

作者： Bibi Estev Ami hommel Faculty of Health and Society Department of Care Sciences Malm&#246 University Malm&#246 Sweden

Aim: The aim of this study was to illuminate registered nurses’ (RNs) perceptions of Trust-Based Public Management (TBPM) in Swedish health care. Design: This study follows a phenomenografic approach guided by Ference Marton’s philosophy. Methods: Semi-structured interviews were used to identify variations in RNs’ perceptions of TBPM. Between February and April 2019, 24 RNs from five Swedish public healthcare departments participated in the study. Results: The results show that none of the participants had previously heard about the work of the Swedish Delegation for TBPM. The study revealed perceptions those politicians and managers were absent from the workplace, that power had been displaced to HR, and that perceptions of trust in the leadership and of working to guidelines varied. Perceptions varied between RNs employed by the municipalities and by the hospitals concerning administration, the time allotted for work, cooperation, and education.

Tianshanbeilu is the largest Bronze Age site in eastern Xinjiang, China. Stretching across the entire second millennium BC, it performed a prominent role in connecting the Hexi corridor, Central China and the steppe. A further insight into the metallurgical tradition and the metal supply network is of vital importance to improve our understanding of its multi-connected nature. This paper offers a new set of chemical and isotopic data on the copper-based objects at Tianshanbeilu, including alloying elements, trace elements(impurities) and lead isotopes. Combining the concentrations of arsenic and antimony reveals that arsenic was introduced to copper partially due to the use of specific minerals tethrahedrite-tennantite. Lead isotopes demonstrate that multiple sources of copper were employed at Tianshanbeilu and a majority of them are characterized by common lead, which appears rather different from those of the Central Plains and the Hexi corridor, but highly consistent with local ores. Surprisingly, one object at Tianshanbeilu contains the well-known highly radiogenic lead. This object undoubtedly marks the westernmost boundary of the distribution of the highly radiogenic lead. We also anticipate that more lead isotopic analyses in NW China will further contribute to the study of the highly radiogenic lead in Central China.

Causes of Surgical Delay and Demographic Characteristics in Patients with Hip Fracture

引用

Open Journal of Orthopedics 2013年第4期3卷 193-198页

作者： Sjostrand Desirée hommel Ami Johansson Anders Department of Clinical Sciences Lund University and Skane University HospitalLundSweden Sections of Anaesthesiology and Intensive Care Department of Clinical SciencesLund University and Skane University HospitalLundSweden

Background: Several studies analyze how surgical delay affects patients with hip fracture. The aim of this study was to identify the causes of surgical delay and demographic characteristics in patients with hip fracture who had delays longer than 24 hours from admission to hospital. Methods: Quantitative retrospective register study of 484 patients was consecutively included during the period November 1, 2010 and October 31, 2011 in the University Hospital in Lund (Sweden). Results: A frequency of 29.4% had a surgical delay longer than 24 hours. The main reasons for delays to surgery were lack of theatre facilities (54%), medical unstable patient (16%) and anticoagulant treatment (10%). Of all patients, 69% (n = 332) were women and 31% (n = 151) were men. The mean age for women were 83.6 (CI 83-85) vs. 79 (CI 77-81) for men, respectively. The most common type of hip fracture was displaced cervical hip fracture (39%, n = 188) with a majority of fractures in male patients. In total, women suffered hip fractures to a greater extent than men (69% vs. 31%, p = 0.016), but no relationship was found with respect to the fracture type and age (p = 0.358). Conclusion: The main result demonstrated that delays longer than 24 hours were due to lack of theatre facilities. Further researches have to be done in order to investigate whether lack of theatre facilities depends on improper operation planning and/or on lack of medical staff.

Blunt Thoracic Aortic Injury in Pediatric Patients: Demographics, Assessment and Treatment

引用

Surgical Science 2013年第2期4卷 160-165页

作者： Christine Gresik Thomas Esposito Dana.hommel Loretto Glynn Robert Love Central Dupage Hospital Winfield USA Loyola University Medical Center Maywood USA Medical College of Wisconsin Milwaukee USA Northwestern University Medical System Chicago USA

Background: There is a paucity of information regarding the management of blunt thoracic aortic injury in the pediatric population compared to adults. This article adds three cases of blunt thoracic aortic injuries in pediatric patients to the literature and analyzes these in conjunction with several of the previous case series which have been published. Methods: Three cases were reviewed along with 38 previously reported cases in an attempt to identify trends in demographics and management. The three new cases presented over a four year period. All are male. A six year old and a 17-year-old were involved in motor vehicle crashes and a 10-year-old was struck by a vehicle while skateboarding. Results: The 6-year-old and the 17-year-old were treated non-interventionally due to severe closed head injuries. One received beta blockade. Both survived. The third, without head injury, underwent interposition graft and also survived. Conclusions: These findings are not greatly dissimilar from the adult experience. In reviewing all 41 pediatric cases, findings reveal a high mortality, predominantly due to head injury as well as the aortic injury. Open repair and interposition grafting continue to be the mainstay of management, with endovascular procedures and non-operative management becoming more prevalent recently. The role of beta-blockade is unclear in children with this injury. Further multicenter prospective studies of this rare pediatric injury may be useful.
