During the course, we carried out a retrospective analysis about clinical data and the course of diagnose and treatment of 38 patients (65 cases) with myasthenia gravis crisis who were in hospital in recent 15 years. As a result, most patients with myasthenia gravis crisis relieved after positive treatment and the mortality was 3.1%. Among lots of treatments, incision of trachea earlier, hormonal therapy, dry treatment and to unite these three treatments were more effective than other treatments. The effective ratio was 100%. In the end, we concluded that to unite incision of trachea, immunosuppressive treatment and dry treatment reasonably can increase the effective ratio of rescuing myasthenia gravis crisis and improve the prognosis of patients obviously.展开更多

文摘Our research was designed to explore the more effective rescuing treatment by summarizing clinical features of the patients with myasthenia gravis crisis. During the course, we carried out a retrospective analysis about clinical data and the course of diagnose and treatment of 38 patients (65 cases) with myasthenia gravis crisis who were in hospital in recent 15 years. As a result, most patients with myasthenia gravis crisis relieved after positive treatment and the mortality was 3.1%. Among lots of treatments, incision of trachea earlier, hormonal therapy, dry treatment and to unite these three treatments were more effective than other treatments. The effective ratio was 100%. In the end, we concluded that to unite incision of trachea, immunosuppressive treatment and dry treatment reasonably can increase the effective ratio of rescuing myasthenia gravis crisis and improve the prognosis of patients obviously.

文摘Post-earthquake rescue missions are full of challenges due to the unstable structure of ruins and successive aftershocks.Most of the current rescue robots lack the ability to interact with environments,leading to low rescue efficiency.The multimodal electronic skin(e-skin)proposed not only reproduces the pressure,temperature,and humidity sensing capabilities of natural skin but also develops sensing functions beyond it—perceiving object proximity and NO2 gas.Its multilayer stacked structure based on Ecoflex and organohydrogel endows the e-skin with mechanical properties similar to natural skin.Rescue robots integrated with multimodal e-skin and artificial intelligence(AI)algorithms show strong environmental perception capabilities and can accurately distinguish objects and identify human limbs through grasping,laying the foundation for automated post-earthquake rescue.Besides,the combination of e-skin and NO2 wireless alarm circuits allows robots to sense toxic gases in the environment in real time,thereby adopting appropriate measures to protect trapped people from the toxic environment.Multimodal e-skin powered by AI algorithms and hardware circuits exhibits powerful environmental perception and information processing capabilities,which,as an interface for interaction with the physical world,dramatically expands intelligent robots’application scenarios.
文摘Motorized spiral enteroscopy(MSE)is the latest advance in device-assisted enteroscopy.Adverse events related to MSE were discussed in a recent large systematic review and meta-analysis and were directly compared with those of balloon enteroscopy in a case-matched study and a randomized controlled trial.Following the real-life application of MSE,an unexpected safety issue emerged regarding esophageal injury and the technique has been withdrawn from the global market,despite encouraging results in terms of diagnostic and therapeutic yield.We conducted an Italian multicenter real-life prospective study,which was prematurely terminated after the withdrawal of MSE from the market.The primary goals were the evaluation of MSE performance(both diagnostic and therapeutic)and its safety in routine endoscopic practice,particularly in the early phase of introduction in the endoscopic unit.A subanalysis,which involved patients who underwent MSE after unsuccessful balloon enteroscopy,demonstrated,for the first time,the promising performance of MSE as a rescue procedure.Given its remarkable performance in clinical practice and its potential role as a backup technique following a previously failed enteroscopy,it may be more appropriate to refine and enhance MSE in the future rather than completely abandoning it.

文摘Effective path planning is crucial for mobile robots to quickly reach rescue destination and complete rescue tasks in a post-disaster scenario.In this study,we investigated the post-disaster rescue path planning problem and modeled this problem as a variant of the travel salesman problem(TSP)with life-strength constraints.To address this problem,we proposed an improved iterated greedy(IIG)algorithm.First,a push-forward insertion heuristic(PFIH)strategy was employed to generate a high-quality initial solution.Second,a greedy-based insertion strategy was designed and used in the destruction-construction stage to increase the algorithm’s exploration ability.Furthermore,three problem-specific swap operators were developed to improve the algorithm’s exploitation ability.Additionally,an improved simulated annealing(SA)strategy was used as an acceptance criterion to effectively prevent the algorithm from falling into local optima.To verify the effectiveness of the proposed algorithm,the Solomon dataset was extended to generate 27 instances for simulation.Finally,the proposed IIG was compared with five state-of-the-art algorithms.The parameter analysiswas conducted using the design of experiments(DOE)Taguchi method,and the effectiveness analysis of each component has been verified one by one.Simulation results indicate that IIGoutperforms the compared algorithms in terms of the number of rescue survivors and convergence speed,proving the effectiveness of the proposed algorithm.

文摘Background:Failure to rescue has been an effective quality metric in congenital heart surgery.Conversely,mor-bidity and mortality depend greatly on non-modifiable individual factors and have a weak correlation with better-quality performance.We aim to measure the complications,mortality,and risk factors in pediatric patients undergoing congenital heart surgery in a high-complexity institution located in a middle-income country and compare it with other institutions that have conducted a similar study.Methods:A retrospective observational study was conducted in a high-complexity service provider institution,in Cali,Colombia.All pediatric patients undergoing any congenital heart surgery between 2019 and 2022 were included.The main outcomes evaluated in the study were complication,mortality,and failure to rescue rate.Univariate and multivariate logistic regression analysis was performed with mortality as the outcome variable.Results:We evaluated 308 congenital heart sur-geries.Regarding the outcomes,201(65%)complications occurred,23(7.5%)patients died,and the FTR of the entire cohort was 11.4%.The presence of a postoperative complication(OR 14.88,CI 3.06–268.37,p=0.009),age(OR 0.79,CI 0.57–0.96,p=0.068),and urgent/emergent surgery(OR 8.14,CI 2.97–28.66,p<0.001)were the most significant variables in predicting mortality.Conclusions:Failure to rescue is an effective and comparable quality measure in healthcare institutions and is the major contributor to postoperative mortality in congenital heart surgeries.Despite our higher mortality and complication rate,we obtained a comparable failure to rescue rate to high-income countries’health institutions.

文摘BACKGROUND Pancreaticoduodenectomy(PD)is a technically complex operation,with a re-latively high risk for complications.The ability to rescue patients from post-PD complications is as a recognized quality measure.Tailored protocols were instituted at our low volume facility in the year 2013.AIM To document the rate of rescue from post-PD complications with tailored protocols in place as a measure of quality.METHODS A retrospective audit was performed to collect data from patients who experienced major post-PD complications at a low volume pancreatic surgery unit in Trinidad and Tobago between January 1,2013 and June 30,2023.Stan-dardized definitions from the International Study Group of Pancreatic Surgery were used to define post-PD complications,and the modified Clavien-Dindo classification was used to classify post-PD complications.RESULTS Over the study period,113 patients at a mean age of 57.5 years(standard deviation[SD]±9.23;range:30-90;median:56)underwent PDs at this facility.Major complications were recorded in 33(29.2%)patients at a mean age of 53.8 years(SD:±7.9).Twenty-nine(87.9%)patients who experienced major morbidity were salvaged after aggre-ssive treatment of their complication.Four(3.5%)died from bleeding pseudoaneurysm(1),septic shock secondary to a bile leak(1),anastomotic leak(1),and myocardial infarction(1).There was a significantly greater salvage rate in patients with American Society of Anesthesiologists scores≤2(93.3%vs 25%;P=0.0024).CONCLUSION This paper adds to the growing body of evidence that volume alone should not be used as a marker of quality for patients requiring PD.Despite low volumes at our facility,we demonstrated that 87.9%of patients were rescued from major complications.We attributed this to several factors including development of rescue protocols,the competence of the pancreatic surgery teams and continuous,and adaptive learning by the entire institution,cul-minating in the development of tailored peri-pancreatectomy protocols.
文摘Drone or unmanned aerial vehicle(UAV)technology has undergone significant changes.The technology allows UAV to carry out a wide range of tasks with an increasing level of sophistication,since drones can cover a large area with cameras.Meanwhile,the increasing number of computer vision applications utilizing deep learning provides a unique insight into such applications.The primary target in UAV-based detection applications is humans,yet aerial recordings are not included in the massive datasets used to train object detectors,which makes it necessary to gather the model data from such platforms.You only look once(YOLO)version 4,RetinaNet,faster region-based convolutional neural network(R-CNN),and cascade R-CNN are several well-known detectors that have been studied in the past using a variety of datasets to replicate rescue scenes.Here,we used the search and rescue(SAR)dataset to train the you only look once version 5(YOLOv5)algorithm to validate its speed,accuracy,and low false detection rate.In comparison to YOLOv4 and R-CNN,the highest mean average accuracy of 96.9%is obtained by YOLOv5.For comparison,experimental findings utilizing the SAR and the human rescue imaging database on land(HERIDAL)datasets are presented.The results show that the YOLOv5-based approach is the most successful human detection model for SAR missions.

文摘During the rapid spread of COVID-19,first responders are at risk of being exposed to COVID-19 due to their role in providing first aid and responding to an unspecified number of people.This uncertainty can have adverse mental health effects,such as increased anxiety and fear.This study aimed to investigate the degree of association between fear of COVID-19,obsession with COVID-19,and post-traumatic stress disorder(PTSD)in emergency rescue firefighters.The participants were 150 emergency rescue firefighters working in Region S,Korea.They filled out self-report questionnaires:The data obtained through the Fear of COVID-19 Scale,Obsession with COVID-19 Scale,and Impact of Event Scale-Revised Korean version were subjected to nonparametric statistical analysis using SPSS WIN 25.0.The study found a significant correlation between emergency rescue firefighters’fear of COVID-19,obsession with COVID-19,and PTSD.Fear and obsession with COVID-19 were higher among first responder firefighters who were directly involved in COVID-19-related tasks.Furthermore,a one-point increase in obsession was associated with a 2.837-point increase in PTSD.Based on the results,we found that there is a need for effective control of obsessions and fears among first responder firefighters during COVID-19,and we suggest that there is a need for mental health care for first responder firefighters during the pandemic through the development and support of programs to prevent and mitigate obsessions.

文摘BACKGROUND Vonoprazan(VPZ)-based regimens are an effective first-line therapy for Helicobacter pylori(H.pylori)infection.However,their value as a rescue therapy needs to be explored.AIM To assess a VPZ-based regimen as H.pylori rescue therapy.METHODS This prospective,single-center,clinical trial was conducted between January and August 2022.Patients with a history of H.pylori treatment failure were administered 20 mg VPZ twice daily,750 mg amoxicillin 3 times daily,and 250 mg Saccharomyces boulardii(S.boulardii)twice daily for 14 d(14-d VAS regimen).VPZ and S.boulardii were taken before meals,while amoxicillin was taken after meals.Within 3 d after the end of eradication therapy,all patients were asked to fill in a questionnaire to assess any adverse events they may have experienced.At least 4-6 wk after the end of eradication therapy,eradication success was assessed using a 13C-urea breath test,and factors associated with eradication success were explored.RESULTS Herein,103 patients were assessed,and 68 patients were finally included.All included patients had 1-3 previous eradication failures.The overall eradication rates calculated using intention-to-treat and per-protocol analyses were 92.6%(63/68)and 92.3%(60/65),respectively.The eradication rate did not differ with the number of treatment failures(P=0.433).The rates of clarithromycin,metronidazole,and levofloxacin resistance were 91.3%(21/23),100.0%(23/23),and 60.9%(14/23),respectively.There were no cases of resistance to tetracycline,amoxicillin,or furazolidone.In 60.9%(14/23)patients,the H.pylori isolate was resistant to all 3 antibiotics(clarithromycin,metronidazole,and levofloxacin);however,eradication was achieved in 92.9%(13/14)patients.All patients showed metronidazole resistance,and had an eradication rate of 91.3%(21/23).The eradication rate was higher among patients without anxiety(96.8%)than among patients with anxiety(60.0%,P=0.025).No severe adverse events occurred;most adverse events were mild and disappeared without intervention.Good compliance was seen in 95.6%(65/68)patients.Serological examination showed no significant changes in liver and kidney function.CONCLUSION VAS is a safe and effective rescue therapy,with an acceptable eradication rate(>90%),regardless of the number of prior treatment failures.Anxiety may be associated with eradication failure.
文摘BACKGROUND Due to increasing resistance rates of Helicobacter pylori(H.pylori)to different antibiotics,failures in eradication therapies are becoming more frequent.Even though eradication criteria and treatment algorithms for first-line and second-line therapy against H.pylori infection are well-established,there is no clear recommendation for third-line and rescue therapy in refractory H.pylori infection.AIM To perform a systematic review evaluating the efficacy and safety of rescue therapies against refractory H.pylori infection.METHODS A systematic search of available rescue treatments for refractory H.pylori infection was conducted on the National Library of Medicine’s PubMed search platform based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Randomized or non-randomized clinical trials and observational studies evaluating the effectiveness of H.pylori infection rescue therapies were included.RESULTS Twenty-eight studies were included in the analysis of mean eradication rates as rescue therapy,and 21 of these were selected for analysis of mean eradication rate as third-line treatment.For rifabutin-,sitafloxacin-,levofloxacin-,or metronidazole-based triple-therapy as third-line treatment,mean eradication rates of 81.6%and 84.4%,79.4%and 81.5%,55.7%and 60.6%,and 62.0%and 63.0%were found in intention-to-treat(ITT)and per-protocol(PP)analysis,respectively.For third-line quadruple therapy,mean eradication rates of 69.2%and 72.1%were found for bismuth quadruple therapy(BQT),88.9%and 90.9%for bismuth quadruple therapy,three-in-one,Pylera®(BQT-Pylera),and 61.3%and 64.2%for non-BQT)in ITT and PP analysis,respectively.For rifabutin-,sitafloxacin-,levofloxacin-,or metronidazole-based triple therapy as rescue therapy,mean eradication rates of 75.4%and 78.8%,79.4 and 81.5%,55.7%and 60.6%,and 62.0%and 63.0%were found in ITT and PP analysis,respectively.For quadruple therapy as rescue treatment,mean eradication rates of 76.7%and 79.2%for BQT,84.9%and 87.8%for BQT-Pylera,and 61.3%and 64.2%for non-BQT were found in ITT and PP analysis,respectively.For susceptibility-guided therapy,mean eradication rates as third-line and rescue treatment were 75.0%in ITT and 79.2%in PP analysis.CONCLUSION We recommend sitafloxacin-based triple therapy containing vonoprazan in regions with low macrolide resistance profile.In regions with known resistance to macrolides or unavailability of bismuth,rifabutin-based triple therapy is recommended.

文摘Global climate change has been widely recognized as important factors that threaten biodiversity.Rhododendron species are not only famous woody ornamental plants worldwide but are also indispensable components in alpine and subalpine vegetation in southwest China.However,the geographical distribution ranges response of this broad taxonomic group to future climate change remains not be fully understood.Herein,we studied the impact of climate change on the distribution of Rhododendron species in China by predicting the changes in their suitable habitats,centroid,and species richness under three climate change scenarios(SSP1-2.6,SSP2-4.5 and SSP5-8.5)in the 2090s.The species richness changes of Rhododendrons along altitude were also evaluated.In addition,we calculated the phylogenetic signals of distribution response to climate change.We found that the distribution responses of Rhododendron to climate change have weak phylogenetic signals.In the 2090s,the suitable habitats of about 87%of Rhododendron species will be reduced,77%of Rhododendron species are manifested as northward migration.The high species richness of Rhododendrons tends to migrate to transboundary areas with high altitudes in China.Some Rhododendron species with no concern previously should be taken seriously for their high risk of habitat loss under climate change.Thus,the urgent protection of Rhododendron species under climate change need to be paid more attention than previous acknowledged.We recommend carrying out the reintroduction of endangered species in future suitable habitat,strengthening the protection of transboundary areas with high species richness,and focusing on species with few concerns previously.
