Functional status can, however, be objectively measured using validated outcome tools such as the Late-Life Function and Disability Instrument (LLFDI). The purpose of this study was to determine 1) if there was a change over time in functional status, as measured by the LLFDI, in patients who underwent elective cardiac surgery, and if so, 2) what specific aspect(s) of functional status changed. Methods: A prospective longitudinal study of one year was conducted on elective cardiac surgery patients (n = 43) using the self-reported LLFDI, which measures Disability Frequency (frequency of participation in social tasks), Disability Limitation (ability to participate in social tasks) and Function Total (ease in performing routine activities). Higher scores indicate increased function and decreased disability. LLFDI scores were compared at three times (preoperative, six-week and one-year postoperative) using repeated measures ANOVA. Post hoc pairwise comparison was conducted for specific interactions. Results: Both Function Total and Disability Frequency significantly changed over time (p = 0.047 and p = 0.013, respectively). Specifically, patients’ function level was significantly higher one-year postoperative compared to preoperative (M difference = +3.48, SE = 1.48, p = 0.026). Likewise, Disability Frequency scores were significantly higher (i.e. more active) at one-year postoperative versus preoperative (M difference= +5.98, SE = 2.19, p = 0.033). Disability Limitation scores were not significantly different between any time points (p > 0.05). Conclusion: By one-year postoperative, patients demonstrated increased ease in their routine physical activities and were more participatory in social life tasks. Individuals who underwent elective cardiac surgery took more than six weeks to detect notable improvement in functional status, which was expected with a sternotomy approach. This study provides support for the use of the LLFDI as an effective tool to capture functional status in the cardiac population. These findings may assist cardiac patients in recovery timeline expectations.展开更多

The unobservable factors which might have minor impacts on the approval rate are modelized by random elements. The approval rate is initially described by the differential equation and then by the random differential equation including the above unobservable factors. We figure out the formula of the solution for the stochastic differential equation and simulate these solutions to identify the changes of the approval rate over time.展开更多

文摘After Democrats recaptured control of the US House at the 2018 midterms,the ramifications for American domestic and foreign policies have included increased partisan checks on President Donald Trump's proposals for immigration,energy,pollution,taxes,healthcare,and social welfare,and on the Republican Party's conservative agenda overall.After the longest government shutdown in US history over funding for a border wall to keep out illegal immigrants,Trump declared a national emergency in February 2019.Under his administration,US trade pacts with China,Mexico,Canada,Japan,the EU and other countries also face uncertainty.The Indo?Pacific Strategy and relations with Russia and Europe will remain,as is.Yet even if Sino-US trade negotiations progress,bilateral friction over high technology and cultural exchange will likely increase,and disputes over Taiwan,the South China Sea and human rights will continue.

文摘In order to further strengthen the construction and improvement of villager autonomy system with democratic election,democratic decision making,democratic management,and democratic supervision of rural two committees with Chinese characteristics,experience of work team of Longyang District Agricultural Technology Extension Station dispatched to villager committees( or offices) and their guidance on election of rural two committees in 2007-2016 were used,and exploration was made for election of rural two committees from the third to the sixth committees. It summarized achievements and main problems in election of rural two committees and came up with pertinent recommendations.The results of this study are expected to provide certain reference for theory and practice of future villager autonomy.
文摘The proportion of the favorable among voters to a nominee might change over times and depend on different factors for example: talent, reputation, party and even name order on election. The unobservable factors which might have minor impacts on the approval rate are modelized by random elements. The approval rate is initially described by the differential equation and then by the random differential equation including the above unobservable factors. We figure out the formula of the solution for the stochastic differential equation and simulate these solutions to identify the changes of the approval rate over time.
文摘BACKGROUND At present,many studies have reported the risk factors for postoperative intracranial reinfection,including age,sex,time to surgery,duration of postoperative catheterization,emergency procedures,type of disease and cerebrospinal fluid leakage,but the academic community has not reached a unified conclusion.AIM To find factors influencing the surveillance of re-emerging intracranial infections in elective neurosurgical patients.METHODS Ninety-four patients who underwent elective craniotomy from January 1,2015 to December 31,2022 in the Department of Neurosurgery,First Hospital of Jilin University,were included in this study.Of those,45 patients were enrolled in the infection group,and 49 were enrolled in the control group.The clinical data of the patients were collected and divided into three categories,including preoperative baseline conditions,intraoperative characteristics and postoperative infection prevention.The data were analyzed using SPSS 26.0 software.RESULTS There were 23 males and 22 females in the infection group with a mean age of 52.8±15.1 years and 17 males and 32 females in the control group with a mean age of 48.9±15.2 years.The univariate analysis showed that the infection group had higher systolic blood pressures and postoperative temperatures,fewer patients who underwent a supratentorial craniotomy,more patients with a history of hypertension and higher initial postoperative white blood cell counts than the control group,with statistically significant differences(P<0.05).The multifactorial logistic regression analysis showed that a history of hypertension and a high postoperative body temperature were independent risk factors for postoperative infection in neurosurgical patients.CONCLUSION The results obtained in this study indicated that a history of hypertension and a high postoperative body temperature were independent risk factors for postoperative neurological symptoms.

文摘In IoT networks,nodes communicate with each other for computational services,data processing,and resource sharing.Most of the time huge data is generated at the network edge due to extensive communication between IoT devices.So,this tidal data is transferred to the cloud data center(CDC)for efficient processing and effective data storage.In CDC,leader nodes are responsible for higher performance,reliability,deadlock handling,reduced latency,and to provide cost-effective computational services to the users.However,the optimal leader selection is a computationally hard problem as several factors like memory,CPU MIPS,and bandwidth,etc.,are needed to be considered while selecting a leader amongst the set of available nodes.The existing approaches for leader selection are monolithic,as they identify the leader nodes without taking the optimal approach for leader resources.Therefore,for optimal leader node selection,a genetic algorithm(GA)based leader election(GLEA)approach is presented in this paper.The proposed GLEA uses the available resources to evaluate the candidate nodes during the leader election process.In the first phase of the algorithm,the cost of individual nodes,and overall cluster cost is computed on the bases of available resources.In the second phase,the best computational nodes are selected as the leader nodes by applying the genetic operations against a cost function by considering the available resources.The GLEA procedure is then compared against the Bees Life Algorithm(BLA).The experimental results show that the proposed scheme outperforms BLA in terms of execution time,SLA Violation,and their utilization with state-of-the-art schemes.
文摘In the recent presidential election,a most bitter trial of strength since its inde-pendence took place between the“democrats”and the so-called“traditionalists”in Russia.The outcome of this rivalry has a direct bearing on thechoice of Russia’s future development path.The reelection of the incumbent Presi-dent Boris Yeltsin in the second round of the voting has offered the political guaran-tee for the country’s further search for an appropriate development strategy alongthe current track.
文摘In view of the upcoming European elections on May 23-26,CEN and CENELEC published the Declaration "Standards Build Trust" on April 9 to highlight the contribution standards make to achieve the priorities of European policy-making from AI to sustainable energy,up to smart appliances and blockchain,which Europe will need in the coming years to make many important decisions to remain competitive in the world.
