BACKGROUND Hospitalized patients who are colonized with methicillin-resistant Staphylococcus aureus (MRSA) are at high risk for infection after discharge. METHODS We conducted a multicenter, randomized, controlled trial of postdischarge hygiene education, as compared with education plus decolonization, in patients colonized with MRSA (carriers). Decolonization involved chlorhexidine mouthwash, baths or showers with chlorhexidine, and nasal mupirocin for 5 days twice per month for 6 months. Participants were followed for 1 year. The primary outcome was MRSA infection as defined according to Centers for Disease Control and Prevention (CDC) criteria. Secondary outcomes included MRSA infection determined on the basis of clinical judgment, infection from any cause, and infection-related hospitalization. All analyses were performed with the use of proportional-hazards models in the per-protocol population (all participants who underwent randomization, met the inclusion criteria, and survived beyond the recruitment hospitalization) and as-treated population (participants stratified according to adherence). RESULTS In the per-protocol population, MRSA infection occurred in 98 of 1063 participants (9.2%) in the education group and in 67 of 1058 (6.3%) in the decolonization group; 84.8% of the MRSA infections led to hospitalization. Infection from any cause occurred in 23.7% of the participants in the education group and 19.6% of those in the decolonization group; 85.8% of the infections led to hospitalization. The hazard of MRSA infection was significantly lower in the decolonization group than in the education group (hazard ratio, 0.70; 95% confidence interval [CI], 0.52 to 0.96; P=0.03; number needed to treat to prevent one infection, 30; 95% CI, 18 to 230); this lower hazard led to a lower risk of hospitalization due to MRSA infection (hazard ratio, 0.71; 95% CI, 0.51 to 0.99). The decolonization group had lower likelihoods of clinically judged infection from any cause (hazard ratio, 0.83; 95% CI, 0.70 to 0.99) and infection-related hospitalization (hazard ratio, 0.76; 95% CI, 0.62 to 0.93); treatment effects for secondary out-comes should be interpreted with caution owing to a lack of prespecified adjustment for multiple comparisons. In as-treated analyses, participants in the decolonization group who adhered fully to the regimen had 44% fewer MRSA infections than the education group (hazard ratio, 0.56; 95% CI, 0.36 to 0.86) and had 40% fewer infections from any cause (hazard ratio, 0.60; 95% CI, 0.46 to 0.78). Side effects (all mild) occurred in 4.2% of the participants. CONCLUSIONS Postdischarge MRSA decolonization with chlorhexidine and mupirocin led to a 30% lower risk of MRSA infection than education alone.

Social interactions in rodents are rewarding and motivating and social isolation is aversive. Accumulating evidence suggests that disruption of the social environment in adolescence has long-term effects on social interactions, on anxiety-like behavior and on stress reactivity. In previous work we showed that adolescent isolation produced increased reactivity to acute and to repeated stress in female rats, whereas lower corticosterone responses to acute stress and decreased anxiety-related behavior were noted in isolated males. These results indicate a sex specific impact on the effects of social stress in adolescence. However, little is known about whether social isolation impacts behaviors related to affect and whether it does so differently in male and female rats. The present study investigated the impact of adolescent social isolation from day 30-50 of age in male and female Sprague Dawley rats on behavior in the forced swim test at the end of adolescence and in adulthood and on behavior in the sucrose preference test in adulthood. Adult female rats that were isolated in adolescence exhibited increased climbing on the first and second day of the forced swim test and showed an increased preference for sucrose compared to adult females that were group-housed in adolescence. There were no effects in male rats. The results indicate that social isolation in adolescence produces a stable and active behavioral phenotype in adult female rats.

Objective:To assess the impact of a newly developed Central-Line Insertion Site Assessment (CLISA) score on the incidence of local inflammation or infection for CLABSI prevention.Design:A pre- and postintervention, quasi-experimental quality improvement study.Setting and participants:Adult inpatients with central venous catheters (CVCs) hospitalized in an intensive care unit or oncology ward at a large academic medical center.Methods:We evaluated CLISA score impact on insertion site inflammation and infection (CLISA score of 2 or 3) incidence in the baseline period (June 2014–January 2015) and the intervention period (April 2015–October 2017) using interrupted times series and generalized linear mixed-effects multivariable analyses. These were run separately for days-to-line removal from identification of a CLISA score of 2 or 3. CLISA score interrater reliability and photo quiz results were evaluated.Results:Among 6,957 CVCs assessed 40,846 times, percentage of lines with CLISA score of 2 or 3 in the baseline and intervention periods decreased by 78.2% (from 22.0% to 4.7%), with a significant immediate decrease in the time-series analysis (P < .001). According to the multivariable regression, the intervention was associated with lower percentage of lines with a CLISA score of 2 or 3, after adjusting for age, gender, CVC body location, and hospital unit (odds ratio, 0.15; 95% confidence interval, 0.06–0.34; P < .001). According to the multivariate regression, days to removal of lines with CLISA score of 2 or 3 was 3.19 days faster after the intervention (P < .001). Also, line dwell time decreased 37.1% from a mean of 14 days (standard deviation [SD], 10.6) to 8.8 days (SD, 9.0) (P < .001). Device utilization ratios decreased 9% from 0.64 (SD, 0.08) to 0.58 (SD, 0.06) (P = .039).Conclusions:The CLISA score creates a common language for assessing line infection risk and successfully promotes high compliance with best practices in timely line removal.

BACKGROUND The CLEAR trial demonstrated that a multi-site body decolonization regimen reduced post-discharge infection and hospitalization in methicillin-resistant Staphylococcus aureus (MRSA) carriers. This report describes decolonization efficacy in clearing site-specific MRSA colonization during the trial. METHODS We performed a large, multi-center, randomized clinical trial of MRSA decolonization among adult patients after hospital discharge with MRSA infection or colonization. Participants were randomized 1:1 to either MRSA prevention education or education plus decolonization with 4% topical chlorhexidine daily, 0.12% oral chlorhexidine rinse twice daily, and 2% nasal mupirocin twice daily. The intervention was given for five consecutive days twice monthly. Participants were swabbed in the nares, throat, axilla/groin, and wound (if applicable) at baseline, 1, 3, 6, and 9 months after randomization. The primary outcomes of this report are follow-up colonization differences between groups. RESULTS Among 2,121 participants, 1,058 were randomized to the decolonization group. By one month, MRSA colonization was lower in the decolonization group compared to the education only group (OR = 0.44 [95% Confidence Interval 0.36-0.54, p≤0.001). Similar magnitude of reduction was seen in the nares (OR = 0.34 [0.27-0.42], p &lt; 0.001) throat (OR = 0.55 [0.42-0.73], p &lt; 0.001), and axilla/groin (OR = 0.57 [0.43-0.75], p &lt; 0.001). These differences persisted through month 9 except at the wound site, which had a relatively small sample size. Higher regimen adherence was associated with lower MRSA colonization (p≤0.01). CONCLUSION In a randomized clinical trial, a repeated post-discharge decolonization regimen for MRSA carriers reduced MRSA colonization overall and at multiple body sites. Higher treatment adherence was associated with greater reductions in MRSA colonization.

Objective: To assess the potential clinical efficacy of a novel model of energy psychology intervention, Advanced Integrative Therapy (AIT), this pilot study assessed clinician perceptions of AIT through a cross-sectional survey. Methods: A 17-item web-based questionnaire was administered to AIT therapists in November of 2021. The survey included clinician demographics and the clinician-observed response to AIT treatment based upon changes in reported Subjective Units of Distress (SUD), the associated emotion, and somatic sensation (when present). Results: A total of 76 complete responses were analyzed. The sample respondents were predominantly female (81.6%) and non-Hispanic white (68%). Over 80% of the respondents reported using AIT with their clients within the past six months and a significant proportion of participants self-assessed their AIT skills as of proficient or expert level. As reported by the therapists, 77% of the sessions described were used to clear patterns of negative events rather than a single event. Over 75% of events were identified as being either since childhood or otherwise chronic in nature. The average pre-AIT intervention SUD score was reported as 8.3±2.7 out of 10, which in 92% of cases, dropped to either 0 or 1 following a single session of AIT. Conclusions: Although this pilot study was limited to clinician responses in assessment of the ability of AIT to reduce the negative emotions related to past traumatic events, the initial observations were supportive of the potential clinical utility of this energy psychology technique. The findings suggest that additional client-based assessments and randomized clinical trials with known therapies as a control are warranted to continue the systematic observation of AIT.
