AbstractObjective:To evaluate the effectiveness of chlorhexidine (CHG) dressings to prevent catheter-related bloodstream infections (CRBSIs).Design:Systematic review and meta-analysis.Methods:We searched PubMed, CINAHL, EMBASE, and ClinicalTrials.gov for studies (randomized controlled and quasi-experimental trials) with the following criteria: patients with short- or long-term catheters; CHG dressings were used in the intervention group and nonantimicrobial dressings in the control group; CRBSI was an outcome. Random-effects models were used to obtain pooled risk ratios (pRRs). Heterogeneity was evaluated using the I2 test and the Cochran Q statistic.Results:In total, 20 studies (18 randomized controlled trials; 15,590 catheters) without evidence of publication bias and mainly performed in intensive care units (ICUs) were included. CHG dressings significantly reduced CRBSIs (pRR, 0.71; 95% CI, 0.58–0.87), independent of the CHG dressing type used. Benefits were limited to adults with short-term central venous catheters (CVCs), including onco-hematological patients. For long-term CVCs, CHG dressings decreased exit-site/tunnel infections (pRR, 0.37; 95% CI, 0.22–0.64). Contact dermatitis was associated with CHG dressing use (pRR, 5.16; 95% CI, 2.09–12.70); especially in neonates and pediatric populations in whom severe reactions occurred. Also, 2 studies evaluated and did not find CHG-acquired resistance.Conclusions:CHG dressings prevent CRBSIs in adults with short-term CVCs, including patients with an onco-hematological disease. CHG dressings might reduce exit-site and tunnel infections in long-term CVCs. In neonates and pediatric populations, proof of CHG dressing effectiveness is lacking and there is an increased risk of serious adverse events. Future studies should investigate CHG effectiveness in non-ICU settings and monitor for CHG resistance.

Background: Catheter-related bloodstream infections (CRBSIs) are associated with significant morbidity and mortality. We aimed to determine the effectiveness of chlorhexidine (CHG) dressings in preventing incident CRBSI in different settings and types of catheters. Methods: We searched PubMed, Cochrane Library, CINAHL, Embase, and ClinicalTrials.gov through March 2019 for studies with the following inclusion criteria: (1) population consisted of patients requiring short or long-term catheters; (2) CHG dressing was used in the intervention group and a nonantimicrobial impregnated dressing was used in the control group; (3) CRBSI was reported as an outcome. Randomized controlled trials (RCTs) and quasi-experimental studies were included. We used a random-effect models to obtain pooled OR estimates. Heterogeneity was evaluated with I 2 test and the Cochran Q statistic. Results: The review included 21 studies (17 RCTs). The use of CHG dressings was associated with a lower incidence of CRBSI (pooled RR, 0.63; 95% CI, 0.53–0.76). There was no evidence of publication bias. In stratified analyses, CHG dressing reduced CRBSI in ICU adult patients (9 studies, pRR, 0.52; 95% CI, 0.38–0.72) and adults with oncohematological disease (3 studies, pRR, 0.53; 95% CI, 0.35–0.81) but not in neonates and pediatric populations (6 studies, pRR, 0.90; 95% CI, 0.57–1.40). When stratified by type of catheter, CHG dressing remained protective against CRBSI in short-term venous catheters (11 studies, pRR, 0.65; 95% CI, 0.48–0.88) but not in long-term catheters (3 studies, pRR, 0.76:; 95% CI, 0.19–3.06). Other subgroup analyses are shown in Table 1. Conclusions: CHG dressings reduce the incidence of CRBSI, particularly in adult ICU patients and adults with an onco-hematological disease. Future studies need to evaluate the benefit of CHG in non-ICU settings, in neonates and pediatric populations, and in long-term catheters.Funding: NoneDisclosures: None

BACKGROUND Mobile health (mHealth) interventions can increase physical activity (PA); however, their long-term impact is not well understood. OBJECTIVE The primary aim of this study is to understand the immediate and long-term effects of mHealth interventions on PA. The secondary aim is to explore potential effect moderators. METHODS We performed this study according to the Cochrane and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched PubMed, the Cochrane Library, SCOPUS, and PsycINFO in July 2020. Eligible studies included randomized controlled trials of mHealth interventions targeting PA as a primary outcome in adults. Eligible outcome measures were walking, moderate-to-vigorous physical activity (MVPA), total physical activity (TPA), and energy expenditure. Where reported, we extracted data for 3 time points (ie, end of intervention, follow-up ≤6 months, and follow-up &gt;6 months). To explore effect moderators, we performed subgroup analyses by population, intervention design, and control group type. Results were summarized using random effects meta-analysis. Risk of bias was assessed using the Cochrane Collaboration tool. RESULTS Of the 2828 identified studies, 117 were included. These studies reported on 21,118 participants with a mean age of 52.03 (SD 14.14) years, of whom 58.99% (n=12,459) were female. mHealth interventions significantly increased PA across all the 4 outcome measures at the end of intervention (walking standardized mean difference [SMD] 0.46, 95% CI 0.36-0.55; <i>P</i>&lt;.001; MVPA SMD 0.28, 95% CI 0.21-0.35; <i>P</i>&lt;.001; TPA SMD 0.34, 95% CI 0.20-0.47; <i>P</i>&lt;.001; energy expenditure SMD 0.44, 95% CI 0.13-0.75; <i>P</i>=.01). Only 33 studies reported short-term follow-up measurements, and 8 studies reported long-term follow-up measurements in addition to end-of-intervention results. In the short term, effects were sustained for walking (SMD 0.26, 95% CI 0.09-0.42; <i>P</i>=.002), MVPA (SMD 0.20, 95% CI 0.05-0.35; <i>P</i>=.008), and TPA (SMD 0.53, 95% CI 0.13-0.93; <i>P</i>=.009). In the long term, effects were also sustained for walking (SMD 0.25, 95% CI 0.10-0.39; <i>P</i>=.001) and MVPA (SMD 0.19, 95% CI 0.11-0.27; <i>P</i>&lt;.001). We found the study population to be an effect moderator, with higher effect scores in sick and at-risk populations. PA was increased both in scalable and nonscalable mHealth intervention designs and regardless of the control group type. The risk of bias was rated high in 80.3% (94/117) of the studies. Heterogeneity was significant, resulting in low to very low quality of evidence. CONCLUSIONS mHealth interventions can foster small to moderate increases in PA. The effects are maintained long term; however, the effect size decreases over time. The results encourage using mHealth interventions in at-risk and sick populations and support the use of scalable mHealth intervention designs to affordably reach large populations. However, given the low evidence quality, further methodologically rigorous studies are warranted to evaluate the long-term effects.

BACKGROUND Growing numbers of people use medication for chronic conditions; non-adherence is common, leading to poor disease control. A newly developed web-based tool to identify an increased risk for non-adherence with related potential individual barriers might facilitate tailored interventions and improve adherence. OBJECTIVE To assess the effectiveness of the newly developed tool to improve medication adherence. METHODS A cluster randomized controlled trial assessed the effectiveness of this adherence tool in patients initiating cardiovascular or oral blood glucose lowering medication. Participants were included in community pharmacies. They completed an online questionnaire comprising an assessments of their risk for medication non-adherence and subsequently of barriers to adherence. In pharmacies belonging to the intervention group, individual barriers displayed in a graphical profile on a tablet were discussed by pharmacists and patients at high non-adherence risk in face to face meetings and shared with their general practitioners and practice nurses. Tailored interventions were initiated by the healthcare providers. Barriers of control patients were not presented or discussed and these patients received usual care. The primary outcome was the difference in medication adherence at 8 months follow-up between patients with an increased non-adherence risk from intervention and control group, calculated from dispensing data. RESULTS Data from 492 participants in 15 community pharmacies were available for analyses (intervention 253, 7 pharmacies; control 239, 8 pharmacies). The intervention had no effect on medication adherence (-0.01; 95%CI -0.59 – 0.57; P= .96), neither in the post hoc per protocol analysis (0.19; 95%CI -0.50 – 0.89; P=.58). CONCLUSIONS This study showed no effectiveness of a risk stratification and tailored intervention addressing personal barriers for medication adherence. Various potential explanations for lack of effect were identified. These explanations relate for instance to high medication adherence in the control group, study power and fidelity. Process evaluation should elicit possible improvements and inform the redesign of intervention and implementation. CLINICALTRIAL The Netherlands National Trial Register: NTR5186.

Abstract Background It was not yet fully established whether the use of antiplatelet agents (APAs) is associated with an increased risk of colorectal post-polypectomy bleeding (PPB). Temporarily, discontinuation of APAs could reduce the risk of PPB, but at the same time, it could increase the risk of cardiovascular disease recurrence. This study aimed to assess the PPB risk in patients using APAs compared to patients without APAs or anticoagulant therapy who had undergone colonoscopy with polypectomy. Methods A systematic electronic search of the literature was performed using PubMed/MEDLINE, Scopus, and CENTRAL, to assess the risk of bleeding in patients who do not interrupt single antiplatelet therapy (P2Y12 inhibitors or aspirin) and undergone colonoscopy with polypectomy. Results Of 2417 identified articles, 8 articles (all of them were non-randomized studies of interventions (NRSI); no randomized controlled trials (RCT) were available on this topic) were selected for the meta-analysis, including 1620 patients on antiplatelet therapy and 13,321 controls. Uninterrupted APAs single therapy was associated with an increased risk of PPB compared to the control group (OR 2.31; CI 1.37–3.91). Patients on P2Y12i single therapy had a higher risk of both immediate (OR 4.43; CI 1.40–14.00) and delayed PPB (OR 10.80; CI 4.63–25.16) compared to the control group, while patients on aspirin single therapy may have a little to no difference increase in the number of both immediate and delayed PPB events. Conclusions Uninterrupted single antiplatelet therapy may increase the risk of PPB, but the evidence is very uncertain. The risk may be higher in delayed PPB. However, in deciding to discontinue APAs before colonoscopy with polypectomy, the potential higher risk of major adverse cardiovascular events should always be assessed.

Abstract BackgroundGlobally, 45% of under-five deaths are, directly or indirectly, attributable to malnutrition, most of these deaths are in low- and middle-income countries (LMICs). Children in the first 6 months of life are particularly vulnerable. An estimated 4.7 million infants under the age of 6 months are moderately wasted whereas 3.8 million are severely wasted. Despite the increased risk to a child of a mother with nutritional decompensation, there are discrepancies in guidance in this area. MethodsThis is a community-based, open-label factorial randomized controlled trial, using parallel assignment with 1:1:1 allocation ratio, in low-income squatter settlements of urban Karachi, Pakistan. In the control group (Arm A), women are randomized to standard counseling only; whereas in the first intervention group (Arm B), lactating women receive two sachets of balanced energy-protein (BEP) supplementation per day from enrollment till the infant reaches six months of age, in the second intervention group (Arm C), lactating women receive same BEP as in intervention Arm B while their babies also receive a single stat dose (20mg/kg orally) of azithromycin at 42 days. The primary outcome is relative length velocity from 0 to 6 months by the limb of allocation. The primary analysis will be Intention-to-treat analysisTrial registrationRegistration of the trial is done at ClinicalTrials.gov. NCT03564652, registered on June 21, 2018.

Abstract Objective: The meta-analysis aims to identify whether out of hospital cardiac arrest (OHCA) survivors of non ST-segment elevation (NSTE) can benefit from early coronary angiography (CAG) and percutaneous coronary intervention (PCI).Methods: The relevant studies from MEDLINE, Cochrane Library, Embase were searched by two independent investigators using a variety of keywords. Stata software (version 12.0, Stata Corp LP, College Station, TX, USA) was used for statistical analysis. Results: A total of 12 studies (9 observational studies, 1 cohort study and 2 randomized control trials) were identified and incorporated into the meta-analysis. For overall analysis, the strategy of early angiography was associated with decreased short-term (hospital discharged) mortality (RR=0.72, 95% CI=0.56-0.93, P=0.000) and long-term (follow up) mortality (RR=0.84, 95% CI=0.71-0.99, P=0.007). However, when analyzed in the subgroup of randomized controlled study, the strategy of early angiography didn’t have survival benefit in the randomized controlled study group for short-term mortality (RR=1.12, 95% CI=0.89-1.41, P=0.331) and long-term mortality (RR=1.06, 95% CI=0.85-1.32, P=0.572). Meanwhile, our analysis found that, if early CAG performed, PCI followed by CAG is not associated with hospital discharged mortality (RR=1.14, 95% CI=0.96-1.37, P=0.132) compared with CAG alone. No significant differences between the groups were found in the remaining secondary endpoints.Conclusion: Due to the observational nature of the studies available, we may consider that early CAG and PCI is not be recommended for patients with NSTE OHCA.

Background: Many clinical trials have been conducted to verify the effects of interventions for prevention of type 2 diabetes (T2D) using different treatments and outcomes. The aim of this study was to compare the effectiveness of lifestyle modifications (LM) with other treatments in persons at high risk of T2D by a network meta-analysis (NMA). Methods: Searches were performed of PUBMED up to January 2018 to identify randomized controlled trials. The odds ratio (OR) with onset of T2D at 1 year in the intervention group (LM, dietary, exercise, or medication) versus a control group (standard treatments or placebo) were the effect sizes. Frequentist and Bayesian NMAs were conducted. Results: Forty-seven interventions and 12 treatments (20,113 participants) were used for the analyses. The OR in the LM was approximately 0.46 (95% CI: 0.33 to 0.61) times lower compared to the standard intervention by the Bayesian approach. The effects of LM compared to other treatments by indirect comparisons were not significant. Conclusions: This meta-analysis further strengthened the evidence that LM reduces the onset of T2D compared to standard and placebo interventions and appears to be at least as effective as nine other treatments in preventing T2D.

BackgroundAlthough depression is a common problem among non-professional caregivers, only one trial has evaluated the efficacy of indicated prevention targeting this population and the long-term efficacy is unknown. The aim of this study was to evaluate the long-term efficacy of a brief intervention for the indicated prevention of depression in a sample of female caregivers.MethodA randomized controlled trial was conducted involving 173 participants (mean age 53.9 years) who were allocated to the intervention (n = 89) or the usual-care control group (n = 84). Blinded interviewers conducted assessments at 1, 3, 6 and 12 months of follow-up. The main outcome measure was the incidence of major depression and the secondary outcomes were compliance with treatment, depressive symptoms, emotional distress and caregiver burden.ResultsAt the 12-month follow-up, a lower incidence of depression as evaluated using the Structured Clinical Interview for Axis I Disorders of the DSM-IV was found in the intervention group compared with the control group (10.1%v.25.0%). The relative risk was 0.40 and statistically significant [χ2 = 6.68, degrees of freedom = 1,p = 0.010, 95% confidence interval (CI) 0.20–0.81], and the number needed to treat was 7 (95% CI 4–27). There was a significant delay in the onset of depression in the intervention group (p = 0.008). The good complier caregivers had a lower incidence of depression. The intervention effect on depressive symptoms, emotional distress and caregiver burden were maintained for 12 months.ConclusionsThis is the first study to demonstrate that a brief problem-solving intervention can prevent the onset of depression among non-professional caregivers over the longer term.

Objective: To evaluate the effect of pharmaceutical care (PC) programs on blood pressure control in individuals with hypertension. Methods: Studies were retrieved by searching MEDLINE, EMBASE, Cochrane, CNKI, and CBM databases from 1999 to February 2008. Randomized controlled trials (RCTs) on the association of pharmaceutical care programs with blood pressure control in individuals with hypertension were included in this study. Moreover, the studies were selected independently by 2 authors. The analysis was conducted by using Review Manager version 4.2 software. Results: Five RCTs with a total of 585 patients with hypertension were included in this meta-analysis. Compared with the control group, the PC program intervention group had significantly lower endpoint systolic blood pressure (SBP) and diastolic blood pressure (DBP). Moreover, SBP and DBP were significantly improved in the intervention group relative to the control group. Conclusions: PC programs appear to be an effective tool in helping to control blood pressure in hypertensive patients.

Background: Clinical pathway recommend the use of short-term prophylaxis antibiotics for cesarean section. Long-term antibiotics or multiple doses was found in clinical practice. There are differences in the mode of administration and the number of doses administered at sardjito hospital.Objective: To determine the effectiveness of short-term antibiotic prophylaxis in cesarean section appropriate to clinical pathway in the prevention of surgical site infection (ssi), the incidence of fever, dysuria events, length of stay.Method: The study used randomized clinical trial. The study subjects who underwent cesarean section and meet the inclusion and exclusion criteria in the period July 2013 to January 2014 divided into an intervention group (n = 52) who received ampicillin 2 gram pre and post-cesarean section, and a control group (n = 54) who received ampicillin 2 gram pre cesarean section and 1 gram every 8 hours for 6 times. Observed on days 3 and 10 post-cesarean section. The primary outcomes assessed were the incidence of surgical wound infection based on the criteria of surgical site infection from Centers for Disease Controland Prevention. Secondary outcomes assessed were the incidence of fever, dysuria events, length of stay. Homogeneity analysis were conducted on subject. Outcome analysis performed bivariate with t test and chi squared test.Results and Discussion : A total of 106 subjects can be analyzed. SSI events in the intervention group at day 3 was 3.8% (n = 52) and control group was 1.84% (n = 54) with p>0.05 RR 2.077 (95% CI 0.194 to 22.219). SSI on day 10 of 7.7% (n = 52) in the intervention group versus 9.3% (n = 54) in controls with p<0.05 RR 0.831 (CI 95%, 0.236 to 2.924). Fever events on day 3 by 5.8% in the intervention group versus 3.7% incontrols with p>0.05 RR 1.558 (95% CI 0.271 to 8.948) and on day 10 was 3.8% versus 3.7 % with p>0.05 RR 1.038 (95% CI 0.152 to 7.102). Dysuria not found on day 3 and but on 10 found 5.8% in the intervention group versus 11.1% with p>0.05 RR 0.519 (IK95% 0.137 to 1.968). Length of stay after cesarean section for 3.21 ± 0.412 days in the intervention group and 3.26 ± 0.442 days in the control group with p>0.05 (95% CI -0.213 - 0.117).Conclusion: There is no significant difference in the incidence of surgical wound infections, the incidence of fever, dysuria, length of stay between short-term prophylaxis antibiotics ampicillin appropriate to clinical pathway and long-term or multiple doses prophylaxis antibiotics. Short term antibiotics prophylaxis are more efficiently with the same effectiveness in preventing outcomes research.Keywords: prophylaxis antibiotics, ampicillin, short term regimen, long term regimen, cesarean section, surgical site infection.
