RESUMO
Objective@#This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. @*Methods@#Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. @*Results@#The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. @*Conclusion@#PMTS is safe and effective in improving insomnia disorders.
RESUMO
<p><b>OBJECTIVE</b>To investigate the distribution and drug sensitivity of pathogenic bacteria isolated from patients with nosocomial infection in intensive care unit.</p><p><b>METHODS</b>The clinical data were collected from 229 hospitalized patients with nosocomial infection in intensive care unit from 2009 to 2011.</p><p><b>RESULTS</b>Gram-negative bacteria were the main pathogens (68.25%) in the intensive care unit. From 2009 to 2011, the annual isolation rate of multidrug-resistant baumannii showed a significant reduction with time (39.13%, 18.18%, and 15%, respectively, P<0.05), while the prevalence of multidrug-resistant Pseudomonas aeruginosa, ESBLs-producing Escherichia coli and Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus, coagulase-negative staphylococci methicillin-resistant strains showed no significant changes in the 3 years (P>0.05). The overall sensitivity of gram-negative bacilli to the antimicrobial agents tended to increase with time. The Gram-negative bacilli remained highly sensitive to carbapenems, tigecycline, amikacin and piperacillin/tazobactam; the Gram-positive bacilli were highly sensitive to vancomycin, quinoline Nupu Ting/dalfopristin, linezolid, and tigecycline with sensitivity rates all reaching 100%.</p><p><b>CONCLUSION</b>Adherence to the principles of antibiotic use and effective monitoring and preventive measures are encouraged to reduce antibiotic resistance rates of the bacteria and the incidences of hospital infection.</p>
