Objective To investigate the causes of an outbreak of healthcare-associated infection with methicillin-resist-ant Staphylococcus aureus (MRSA)in a neurosurgical intensive care unit(NSICU).Methods Epidemiological investigation on 8 patients with lower respiratory tract infection (LRTI)in a NSICU between June 15 and June 28,2104 were performed by combination methods of prospective and retrospective survey.Results The attack rate of MRSA LRTI in NSICU patients was 22.86%,a total of 16 MRSA isolates were detected from patients’clinical specimens,nasal vestibule,as well as hospital surroundings during the period,pulsed-field gel electrophoresis (PFGE)result revealed that infection outbreak was caused by two subtypes of MRSA;risk factors analysis showed that long length of stay in ICU and aspiration of spu-tum through bronchoscopy were risk factors for MRSA LRTI.Conclusion Contamination of bronchoscope was the key factor for this epidemic spread of healthcare-associated MRSA infection.

BackgroundPrevention and intervention of procrastination in college students are of great practical significance, and studies have illustrated a pairwise correlation among mindfulness, self-control, insecure attachment and procrastination, whereas the mechanism by which insecure attachment leads to procrastination remains unclear, and the related mediation path is quite understudied. ObjectiveTo investigate the effect of insecure attachment on procrastination among college students and the pathway of mindfulness and self-control, so as to inform the design of interventions for procrastination among college students. MethodsRandom and cluster sampling method were utilized to enroll 514 college students from 4 colleges in Guangdong Province From February to April 2023. Subjects were assessed using Irrational Procrastination Scale (IPS), Adult Attachment Scale (AAS), Mindful Attention Awareness Scale (MAAS) and Brief Self-Control Scale (BSCS). Pearson correlation analysis were adopted to identify the correlation among above scales, and the mediation effect was examined via Bootstrap procedure. ResultsAAS score was positively correlated with IPS score (r=0.382, P<0.01), and negatively correlated with MAAS and BSCS scores (r=-0.242, -0.353, P<0.01). IPS score was negatively correlated with MAAS and BSCS scores (r=-0.314, -0.682, P<0.01). MAAS score was positively correlated with BSCS score (r=0.439, P<0.01). Insecure attachment positively predicted procrastination (β=0.377, P<0.01), and the prediction of procrastination by insecure attachment was mediated by self-control, with an indirect effect value of 0.163 (95% CI: 0.105~0.223), accounting for 43.24% of the total effect value. The mindfulness and self-control exerted a chained mediation effect on the relationship between insecure attachment and procrastination, and the indirect effect value was 0.056 (95% CI: 0.028~0.089), accounting for 14.85% of the total effect value. ConclusionInsecure attachment can influence procrastination among college students both directly and indirectly through the single mediation of self-control or the chained mediation of mindfulness and self-control.
