Methicillin-resistant Staphylococcus aureus is one of the important pathogens of healthcare-associated infections. In order to prevent and control the transmission of the drug-resistant organism in healthcare facilities, the Healthcare Infection Society and the Infection Prevention Society jointly conducted the guidelines for the prevention and control of methicillin-resistant Staphylococcus aureus in 2021. This article introduces the guide from the background, preparation process, main prevention and control measures and further studies, and compares the guidelines with the current prevention and control measures in China, so as to provide a methodological reference for preparation of the guide for domestic infection prevention and control practitioners, and provide evidence-based prevention and control strategies for clinical practice.
Objective To evaluate the clinical result of using osseointegratedimplants to retain removable orbital prostheses in repairing orbital defects. Methods Two patients with orbital defects caused by orbitaltumor were treated. Each of them got 4 implants. After average 6 months, we performed the secondary operation. After 7 weeks, we took impressions to make the implant-retained prostheses. The magnetic attachment was adopted. The prostheses were made of polysiloxane material(Factor II,Lakeside,Ariz). Results Both of the patients got the successful facial prostheses and were followed up 2 and 8 years respectively. All the implants were integrated well. There were no apparent inflammatory reactions in the soft tissue around percutaneous implants. The patients were satisfied with the facial appearance. Conclusion Implant-retained orbital prostheses are safe and effective in repairing orbital defects.

Methods Using a self-designed questionnaire in March 2010, we did a survey on students who attended the course of hospital infection control and occupational protection. Results Among all the students, 92.73% did not know standard prevention measures, and the correct treatment and remedial measures for sharp injuries; 27.27% did not know gloves should be worn at the time of blood drawing; 25.45% did not know the "six-step" hand-washing; and less than one out of ten students used hospital laundry to wash their uniform. Conclusions The students have a low level of relevant knowledge on occupational protection, and their protection behaviors were not complete or standard. Therefore, the teaching should help and support students to have a concept of standard prevention, and acquire sound knowledge and behavior of occupational protection in order to avoid and reduce the risk factors from their future clinical practices.
ObjectiveTo evaluate systematically the relationship between obesity and clinical prognosis in acute respiratory distress syndrome (ARDS) patients.MethodsA systematic search was performed in Pubmed, EMBASE, Cochrane databases, Wiley, Ovid, Medline, CNKI, VIP and Wanfang. All studies that reported obesity in the clinical prognosis of ARDS and acute lung injury were included. A meta-analysis was performed using RevMan 5.0 and Stata 10.0.ResultsA total of 28 368 patients from 9 studies were included in this meta-analysis. The combined results showed that obesity was associated with the decreased mortality of ARDS [odds ratio(OR)=0.63, 95% confidence intervals (95%CI) 0.41 to 0.98, P=0.04]. In subgroup analysis, the result showed no obvious relationship between obesity and 28-day mortality in ARDS/ALI (OR=0.92, 95%CI 0.55 to 1.54, P=0.76). However, obesity was associated with lower risk of 60days and 90-day mortality in ARDS/ALI (60-day: OR=0.84, 95%CI 0.75 to 0.94, P=0.002; 90-day: OR=0.38, 95%CI 0.22 to 0.66, P=0.000 5). Compared with normal weight patients with ARDS, hospital length of stay, ICU length of stay, and duration of mechanical ventilation did not differ significantly [hospital length of stay: weighted mean difference (WMD)=3.61, 95%CI –0.36 to 7.57, P=0.07; intensive care unit (ICU) length of stay: WMD=1.52, 95%CI –0.22 to 3.26, P=0.09; duration of mechanical ventilation: WMD=–0.50, 95%CI –2.18 to 1.19, P=0.56], but ventilator-free days was significantly longer in obese patients (WMD=2.68, 95%CI 0.86 to 4.51, P=0.004).ConclusionsObesity is not associated with hospital length of stay, ICU length of stay, and duration of mechanical ventilation in patients with ARDS. However, obesity is associated with a reduction of long-term mortality and increased ventilator-free days in the patients with ARDS. Additional larger randomized controlled studies are needed to confirm the possible role of obesity in the clinical prognosis of ARDS.
Transthyretin cardiac amyloidosis (ATTR-CA) is a form of restrictive cardiomyopathy characterized by the abnormal deposition of transthyretin in the myocardial interstitium, presenting with clinical manifestations such as heart failure, atrial fibrillation, and cardiac conduction system disorders. The significant individual variability in the symptomatology of ATTR-CA patients poses considerable challenges for precise diagnosis. This study provides a review of biomarkers associated with ATTR-CA and highlights the TTR tetramer as a potential novel indicator. The amyloid deposition in ATTR-CA is closely related to the dissociation of TTR tetramers; however, the TTR tetramer is not included among the biomarkers currently used in clinical practice. Investigating the concentration, profile, and dissociation rate of TTR tetramers holds profound significance for the early detection and prognostic assessment of ATTR-CA. This article synthesizes the research on traditional biomarkers of ATTR-CA and emphasizes the potential application value of TTR tetramers in disease diagnosis and prognostic evaluation.
Objective To observe the effect of pars plana vitrectomy (PPV) with epiretinal membrane peeling (ERMP) and (or) internal limiting membrane peeling (ILMP) and silicone oil tamponade for highly myopic macular hole retinal detachment (MHRD) with posterior staphyloma. Methods Eighty-five highly myopic MHRD patients (85 eyes) were enrolled in this study. All the patients were examined for corrected visual acuity (CVA), slit lamp microscope and preset lens, indirect ophthalmoscope, A/B ultrasound, optical coherence tomography (OCT) and intraocular pressure examination. The average axial length was (29.1plusmn;1.8) mm. There were 24 eyes with diffuse choroid atrophy and 61 eyes with partial choroid atrophy. The CVA was converted into a logarithm of the minimal angle of resolution (logMAR) for statistical analysis. The average logMAR CVA was 1.93plusmn;0.37. All the patients were treated with PPV and triamcinolone acetonide or indocyanine green (ICG) assisted ILMP and (or) ERMP and silicone oil tamponade. TA assisted ERMP was performed in 21 eyes; with ICG assisted ILMP in 56 eyes and TA assisted ILMP in eight eyes. The duration of silicone oil tamponade was (6.2plusmn;1.6) months. CVA, retina and macular hole status and complications were observed postoperatively. Differences between preoperative and postoperative CVA were evaluated by the t test and correlation analysis. Multiple logistic regression analysis was performed to assess the influence of individual preoperative factors on the initial anatomical success. Differences in the macular hole closure rate between eyes with or without macular schisis were evaluated for statistical significance using corrected chi-square. Results The mean logMAR CVA was 1.34plusmn;0.48 after surgery, which significantly improved compared to that before surgery (t=39.38, P＜0.01). The CVA after surgery was independent of axial length (r=0.142, P＞0.05), choroid atrophy (t=0.23, -0.165,P＞0.05) and macular hole closure (t=0.12, -0.005, P＞0.05). The retina reattached in 79 eyes (92.9%) and recurrence of retinal detachment occurred in six eyes (7.1%). Multiple logistic regression analysis indicated that recurrence of retinal detachment was independent of choroid detachment, proliferative vitroretinopathy, axial length, choroid atrophy and ILMP (OR=1.428, 5.039, 0.815, 2.578, 0.432; P＞0.05). Of these 85 eyes, macular hole closed in ten eyes (11.8%), macular hole did not close in 75 eyes (88.2%). There were 24 eyes (28.2%) experienced high intraocular pressure during the first 2 weeks after surgery, all of them were under control with drugs. There were 12 eyes (14.1%) presented with high intraocular pressure before the silicone oil removal, all of them were under control only by silicone oil removal. Conclusion For the treatment of MHRD with posterior staphyloma, PPV combined with ERMP and (or) ILMP and silicone oil tamponade show a high retinal reattachment rate.
ObjectiveTo systematically review the effectiveness of outdoor activities in preventing myopia progression, and to provide scientific evidence for myopia prevention and management.MethodsPubMed, MEDLINE, EMbase, CNKI and WanFang Data databases were searched from establishment to October 2017. Two researchers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 10 studies involving 24 667 participants were included. The results of meta-analysis showed that the incidence of myopia in outdoor activities group was lower than that in control group (OR=0.67, 95%CI 0.55 to 0.81, P<0.000 1).ConclusionThe current evidence shows that outdoor activities have protective effects on emmetropia children myopia onset. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusions.

ObjectiveTo improve activities of daily living (referring to Barthel Index) in the older inpatients.MethodsIn January 2016, a quality control circle (QCC) was established. According to 10 steps in activity of QCC, we figured out the causes of low Barthel Index score in older inpatients by using Plato method and Fishbone Diagram which were common methods of QCC. In addition, we designed and implemented a rectification program to improve Barthel Index score.ResultsAfter intervention of QCC, the average Barthel Index score of the older inpatients increased from 72.40±6.42 to 89.30±5.87 with a statistical difference (P<0.01); the satisfaction percent of hospitalized patients increased from 94.5% to 98.7% with a statistical difference (P<0.01). The percentage of registered nurses whose theoretical test score were over 90 increased from 57% to 88% (P<0.01) and the satisfaction percent of nurses increased from 90.5% to 95.6% (P<0.01). Moreover, the member’s ability of learning, discovery, analysis and problem solving, communication, application of QCC skills were improved.ConclusionThe application of QCC activities will increase older inpatients’ Barthel Index score, improve the satisfaction of patients and nursing staff, and enhance the members’ ability of solving problems by using QCC skills.
