Burn injury is a major public health concern,with an estimated 180,000 deaths each year associated with burn-related infections.The majority of these occur in low-and middle-income countries,and almost two-thirds occur in the World Health Organization African and South-East Asia Regions.There is a risk of an escalation of burn injury site infections if nurses who are directly involved in burn care do not develop a mechanism to mitigate this risk in the coming years.Hence,this study aims at explaining what burn injuries are and how nurses can prevent the occurrence of infection among burn victims.This review analyzed published studies using keywords such as burn injury,infection in burn patients,and nurses’involvement in infection prevention and control(IPC)on search engines such as PubMed,Science Direct,and Google Scholar.The literature was retrieved and reviewed for eligibility to capture just the variables indicated in this seminar objective;the date range chosen in the literature search was from 2015 to 2023.The study found that many patients die from burn injuries as a result of exposure to infection and most nurses are not adequately informed about infection control.The study also found that nurses’responsibilities include proper hand hygiene,wound care,the use of personal protective equipment,antibiotic medication,cleaning the patient’s surroundings,and preventing patient cross-contamination.Burn injuries pose a significant risk to patients,necessitating infection control and prevention.Therefore,nurses in burn units should be informed on IPC practices and also educate patients,families,and coworkers on their importance. 展开更多

There are two kinds of unbalance vibrations—force vibration and displacement vibration due to the existence of unbalance excitation in active magnetic bearings(AMB) system. And two unbalance compensation methods—closed-loop feedback and open loop feed-forward are presented to reduce the force vibration. The transfer function order of the control system directly influencing the system stability will be increased when the closed-loop method is adopted, which makes the real-time compensation not easily achieved. While the open loop method would not increase the primary transfer function order, it provides conditions for real-time compensation. But the real-time compensation signals are not easy to be obtained in the open loop method. To implement real-time force compensation, a new method is proposed to reduce the force vibration caused by the rotor unbalance on the basis of AMB active control. The method realizes real-time and on-line force auto-compensation based on H∞ controller and one novel feed-forward compensation controller, which makes the rotor rotate around its inertia axis. The time-variable feed-forward compensatory signal is provided by a modified adaptive variable step-size least mean square(VSLMS) algorithm. And the relevant least mean square(LMS) algorithm parameters are used to solve the H∞ controller weighting functions. The simulation of the new method to compensate some frequency-variable and sinusoidal signals is completed by MATLAB programming, and real-time compensation is implemented in the actual AMB experimental system. The simulation and experiment results show that the compensation scheme can improve the robust stability and the anti-interference ability of the whole AMB system by using H∞ controller to achieve close-loop control, and then real-time force unbalance compensation is implemented. The proposed research provides a new control strategy containing real-time algorithm and H∞ controller for the force compensation of AMB system. And the stability of the control system is finally improved. 展开更多

Glycemic control among critically-ill patients has been a topic of considerable attention for the past 15 years. An initial focus on the potentially deleterious effects of hyperglycemia led to a series of investigations regarding intensive insulin therapy strategies that targeted tight glycemic control. As knowledge accumulated, the pursuit of tight glycemic control among critically-ill patients came to be seen as counterproductive, and moderate glycemic control came to dominate as the standard practice in intensive care units. In recent years, there has been increased focus on the importance of hypoglycemic episodes, glycemic variability, and premorbid diabetic status as factors that contribute to outcomes among critically-ill patients. This review provides a survey of key studies on glucose control in critical care, and aims to deliver perspective regarding glycemic management among critically-ill patients. 展开更多

Introduction: The incidence and severity of Clostridium difficile infection (CDI) has been increasing and long-term care facility (LTCF) residents are at high risk given their age, co-morbidities, and high antibiotic exposure. Infection control policies are crucial for controlling CDI, but there are currently no regulatory guidelines in the United States. Therefore, we evaluated infection control policies in local LTCFs to define the CDI-specific policies and the administrative and staff understanding of CDI, so as to identify perceived barriers for compliance. Methods: IRB approval was sought and exemption granted, all 8 local LTCFs were asked to participate. Each facility was visited by study personnel who interviewed the administrative Infection Control Practitioner (ICP) and 3-4 Licensed Practical Nurses (LPNs) with distinct survey format. Infection control policies were then compared to the SHEA recommendations for CDI in LTCFs. Results: Of the eligible facilities, 75% (n = 6) participated. ICP (n = 6) and LPNs (n = 21) were interviewed. All facilities accept residents with active CDI and 2 had written CDI-specific infection control policies. All facilities had hand hygiene or glove use policies and 2 had policies for the use of sporicidal environmental cleaning. No facility restricted antibiotic use. Each facility has a policy to instruct their staff through in-services, either annually or upon new hire, but 33% (n = 7) LPNs reported no facility-based CDI training. While 80% (n = 17) of LPNs felt comfortable with the facility CDI policies, only 11 accurately restated it. ICPs felt the most relevant barrier to staff compliance was time constraints (n = 4, 67%), however, LPNs felt it was limited knowledge (n = 10, 48%) and poor communication (n = 2, 10%). Discussion and Conclusions: With the increasing incidence and severity of CDI in LCTF, few of the facilities surveyed had CDI-specific policies. Despite CDI-specific training, there is a perceived knowledge and communication gap for staff caring for residents with CDI. 展开更多

A dynamic velocity feed-forward compensation (RBF-NN) dynamic model identification was presented for control (DVFCC) approach with RBF neural network the adaptive trajectory tracking of industrial robots. The proposed control approach combined the advantages of traditional feedback closed-loop position control and computed torque control based on inverse dynamic model. The feed-forward compensator used a nominal robot dynamics as accurate dynamic model and on-line identification with RBF-NN as uncertain part to improve dynamic modeling accu- racy. The proposed compensation was applied as velocity feed-forward by an inverse velocity controller that can con- vert torque signal into velocity in the standard industrial controller. Then, the need for a torque control interface was avoided in the real-time dynamic control of industrial robot. The simulations and experiments were carried out on a gas cutting manipulator. The results show that the proposed control approach can reduce steady-state error, suppress overshoot and enhance tracking accuracy and efficiency in joint space and Cartesian space, especially under high- speed condition. 展开更多

Objective: We sought to determine any benefits of applying a transitional care model in the continuum of cancer pain management, especially after patients' discharge from the hospital. Methods: A total of 156 eligible participants were recruited and randomly assigned into intervention or control groups. The control group received standard care, while the intervention group received extra, specialized transitional care of pain management. Outcomes were measured at weeks 0 and 2-4 and included demographic data, the Brief Pain Inventory, Global Quality of Life Scale, and Satisfaction Degree of Nursing Service. Adequacy of analgesia and severity of pain were assessed with the Pain Management Index and interview findings. Results: After 2-4 weeks of intervention, there was a significant difference in the change in average pain score between intervention and control groups (P 〈 0.05). Reductions in pain scores were significantly greater in the intervention group than in the control group (difference: 0.98, P 〈 0.05). Regarding pain management outcomes, there was a significantly better condition in the intervention group compared with the control group; in the intervention group, 79% of patients had adequate opioids, whereas in the control group, only 63% of patients reported having adequate opioids. Furthermore, there was a signif- icant difference between the two groups in quality of life (QOL) scores (P 〈 0.05); the intervention group had significantly higher quality of life than the control group (difference: 1.06). Finally, there was a significant difference in the degree of satisfaction with the home nursing service; the intervention group had a significantly higher degree of satisfaction with the home nursing service in three aspects: quality, content, and attitude of service. Conclusions: The application of a transitional care model in cancer pain management after discharge could help patients to improve their cancer pain management knowledge and analgesics compliance. In addition, the continuum of care service will contribute to effective communication between health care providers and patients, which could further improve their relationship. 展开更多

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 effects. 展开更多

In data stream management systems (DSMSs), how to maintain the quality of queries is a difficult problem because both the processing cost and data arrival rates are highly unpredictable. When the system is overloaded, quality degrades significantly and thus load shedding becomes necessary. Unlike processing overloading in the general way which is only by a feedback control (FB) loop to obtain a good and stable performance over data streams, a feedback plus feed-forward control (FFC) strategy is introduced in DSMSs, which have a good quality of service (QoS) in the aspects of miss ratio and processing delay. In this paper, a quality adaptation framework is proposed, in which the control-theory-based techniques are leveraged to adjust the application behavior with the considerations of the current system status. Compared to previous solutions, the FFC strategy achieves a good quality with a waste of fewer resources. 展开更多

Blood glucose control, including hyperglycemia correction, maintaining glucose at optimal level and avoiding hypoglycemia, is a challenge clinicians face every day in intensive care units (ICUs). If managed inadequately, its related mortality can increase. Prior to 2001, no relevant data from randomized, controlled studies assessing glucose control in the ICU were available. In the past 18 years, however, many clinical trials have defined criteria for managing abnormal blood glucose levels, as well as provided suggestions for glycemic monitoring. Point-ofcare blood glucose monitors have become the preferred bedside technology to aid in glycemic management. In addition, in some institutions, continuous glucose monitoring is now available. Cost-effectiveness of adequate glycemic control in the ICU must be taken into consideration when addressing this complex issue. Newer types of glycemic monitoring may reduce nursing staff fatigue and shorten times for the treatment of hyperglycemia or hypoglycemia. There are a variety of glycemic care protocols available. However, not all ICU clinicians are aware of them. The following minireview describes some of these concepts. 展开更多

Introduction: Critically ill patients can experience stress-induced hyperglycaemia. Glycaemic control therapy (GCT) is administered to control patients’ blood glycaemic levels and reduce the incidence of infection, myocardial infarctions and organ failure. However, there are many factors influencing the effectiveness of glycaemic control for patients. This investigation aimed to review the method of Glycaemic Control Therapy (GCT) used in two hospital settings, to assess the effectiveness of glycaemic control on patients’ blood glycaemic levels and examine any barriers that may be in place. Method: A retnrospective audit was carried out on patients’ case notes in Intensive Care Units (ICU) within the East Midlands, UK. This method prevents the study outcomes being swayed because GCT has already taken place. To reduce selection bias the most recent available case notes were selected. All the patients who were admitted to these adult ICU’s between March and April 2010 had their case notes examined, those who were administered GCT were included in the study, this involved 79 from Hospital A and 50 from Hospital B. The patients’ notes were retrospectively audited. Results: Different glycaemic control protocols were being implemented in each hospital, despite both belonging to the same ICU network. In most incidences, regardless of age, diabetes status or diagnosis, patients were administered the same sliding scale insulin (SSI). It was also found that GCT commenced for 41.9% (n = 52) of ICU patients (across both Hospitals) when glycaemic levels were below the established threshold of 10mmol/L. Additionally, a new glycaemic range has been discovered, where 88.3% (n = 113) of patients (across both Hospitals) receiving GCT were not controlled in hypoglycaemia, normoglycaemia or hyperglycaemia. They had mean blood glycaemic levels maintained between 5.6 - 9.9 mmol/L, now being described as medioglycaemia. Conclusions: The majority of patients receiving GCT were controlled in medioglycaemia and therefore a new comprehensive guideline needs to be developed incorporating this new range. Recommendations also need to be established to adapt the titration regimen to individual patients, to improve the effectiveness and safety of glycaemic control. 展开更多

The purpose of this study was to construct the model of organization system,managemcnt,training and surveillance in healthcare-associated infection prevention and control(IC)of primary health care institutions and identify its efleet on patient safety and decreasing economic burden by standardizing IC.A cross-sectional survey was conducted with questionnaires.Data were collected from 268 primary health care institutions in Hubei province,China.Hypotheses on the model of IC were analyzed by means of confirmatory factor analysis and structural equation modeling.The results showed that the fit indices of the hypothesized model of IC satisfied recommended levels:root mean square error of approximation(RMSEA)=0.071;comparative fit index(CFI)=0.965;tucker lewis index(TLI)=0.956:weighted root mean square residual(WRMR)=1.014.The model showed that organization system had a direct effect on management(β=0.311.P<0.01),and training(β=0.365,P<0.01).Management and training played an intermediary role that partially promoted organization system impact on surveillance.Results also showed that institutional factors such as the number of physicians、the ninnber of nurses,the designated capacity of beds,the actual number of open beds and surgery trips had positive impacts on management(β=0.050,P<0.01;β=0.181,P<0.01;β-0.111.P<0.01;β=0.064,P<0.01;β=0.084,P=0.04);nd training(β=0.21,P=0.03;β=0.050,P=0.02;β=0.586.P=0.01;0=0.995,P=0.02;β=0.223.P=0.03).In conclusion.the model of organization system,managemcnt,training and surveillancc in IC of primary health care institutions is valuable tor guiding IC practice. 展开更多

Background: Primary care physicians in Japan see many patients in a given day;consequently, they find it challenging to devote sufficient time for detailed clinical consultation and evaluation of asthma control status. The aim of this study was to investigate asthma symptoms that reveal the presence of inadequately controlled asthma. Methods: A pooled analysis of baseline data from 100 patients with asthma treated with inhaled corticosteroid(s) (ICS) alone or ICS/long-acting beta-agonist who participated in three previous clinical trials was performed. Asthma control status and asthmatic symptoms were determined using a five-item Asthma Control Questionnaire, and whether asthmatic symptoms reflect clinical markers was investigated. Results: Nocturnal awakening owing to asthmatic symptoms was observed only in the uncontrolled asthma group. Patient-reported wheezing was not observed in the group with well-controlled asthma, but was observed in all patients in the uncontrolled asthma group. Virtually all patients, irrespective of asthma control status, reported symptoms in the morning, limitation of normal daily activities, and shortness of breath. Conclusions: The presence of nocturnal awakening due to asthma and wheezing likely reflected uncontrolled asthma. These results will lead to re-recognition that clinical interview, querying nocturnal awakening from asthma and wheezing is a simple and useful approach to assess asthma control status in a primary care setting. 展开更多
