Background.Methicillin-resistantStaphylococcus aureus(MRSA) pulsed-field type (PFT) USA300 causes skin and soft tissue infections in military recruits and invasive disease in hospitals. Chlorhexidine gluconate (CHG) is used to reduce MRSA colonization and infection. The impact of CHG on the molecular epidemiology of MRSA is not known.Objective.To evaluate the impact of 2% CHG—impregnated cloths on the molecular epidemiology of MRSA colonization.Design.Cluster-randomized, double-blind, controlled trial.Setting.Marine Officer Candidate School, Quantico, Virginia, in 2007.Participants.Military recruits.Intervention.Thrice-weekly application of CHG-impregnated or control (Comfort Bath; Sage) cloths over the entire body.Measurements.Baseline and serial (every 2 weeks) nasal and/or axillary swab samples were assessed for MRSA colonization. Molecular analysis was performed with pulsed-field gel electrophoresis.Results.During training, 77 subjects (4.9%) acquired MRSA, 26 (3.3%) in the CHG group and 51 (6.5%) in the control group (P= .004). When analyzed for PFT, 24 subjects (3.1%) in the control group but only 6 subjects (0.8%) in the CHG group (P= .001) had USA300. Of the 167 colonizing isolates recovered from 77 subjects, 99 were recovered from the control group, including USA300 (40.4%), USA800 (38.4%), USA1000 (12.1%), and USA100 (6.1%), and 68 were recovered from the CHG group, including USA800 (51.5%), USA100 (23.5%), and USA300 (13.2%).Conclusions.CHG decreased the transmission of MRSA—more specifically, USA300—among military recruits. In addition, USA300 and USA800 outcompeted other MRSA PFTs at incident colonization. Future studies should evaluate the broad-based use of CHG to decrease transmission of USA300 in hospital settings.

Background: Our study aimed to assess the efficacy of 0.1% Octenidine mouthwash as an anti-plaque agent and to assess its effect on gingival inflammation and staining of teeth when compared to 0.2% chlorhexidine gluconate by evaluating the impact on plaque and gingival inflammation as well as on microbial load. Materials and Methods: A three week double blind study was conducted on 69 subjects, aged 20-50 years, with moderate to severe gingivitis. The study population was divided into three groups with 23 subjects in each group: Group A - control subjects received only scaling, Group B received 0.2% chlorhexidine gluconate in addition to scaling and Group C received 0.1% Octenidine mouthwash along with scaling. Clinical and microbiological parameters were recorded at baseline, on 14th day and on 21st day. Subjective and objective criteria were assessed on the 14th day and 21st day. Results: There was a statistically significant reduction in all the tested parameters within all the three groups and between the groups from baseline to 21st day. The highest mean reduction in all the parameters was seen in subjects using 0.1% Octenidine. On comparison with the control group, subjects using the mouthwashes (Group B and Group C) had better improvement in clinical and microbiological parameters from baseline to 21st day. On comparison with chlorhexidine, Octenidine mouthwash significantly reduced plaque (p<0.05) and showed better patient acceptability. However, it was comparable to chlorhexidine in other two tested parameters. Conclusion: Owing to Octenidine’s pronounced and comparable antibacterial properties, it can be a promising candidate for the use in antiseptic mouthwashes.

Abstract Background: Posterior canal benign paroxysmal positional vertigo (pc-BPPV) causes physical, functional, and emotional impairment. The treatment of choice is the Epley manoeuvre (EM). The purpose of the study was to compare the impact of the EM and a sham manoeuvre in primary care on self-perceived disability.Method: Randomised, double-blind, sham-controlled clinical trial conducted in primary care with a follow-up of 1 year. Patients aged ≥18 years old diagnosed with pc-BPPV according to the Dix-Hallpike test (DHT) were randomised to an intervention (EM) group or a control (sham manoeuvre) group. The main study covariables were age, sex, history of depression and anxiety, presence of nystagmus in the DHT, patient-perceived disability assessed with the Dizziness Handicap Inventory-screening version (DHI-S). Data were analyzed using bivariate and multivariate mixed Tobit analyses. Results: Overall, 134 patients were studied: 66 in the intervention group and 68 in the control group. Median age was 52 years (interquartile range [IQR], 38.25–68.00 years) and 76.12% of the patients were women. The DHT triggered nystagmus in 40.30% of patients. The median total DHI-S score for the overall sample at baseline was 16 (IQR, 8.00–22.00); 16 [IQR, 10.5–24.0] vs 10 [6.0–14.0] for women vs men (P<0.001) and 16 [IQR, 10.0-24.0] vs 12 [IQR, 8.0–18.0] for patients without nystagmus vs those with nystagmus (P=0.033).Patients treated with the EM experienced a mean reduction of 2.03 points in DHI-S score over the follow-up period compared with patients in the sham group. Conclusion: Pc-BPPV affects the quality of life of primary care patients. A single EM can improve self-perceptions of disability by around 2 points on the DHI-S scale, Trial registration: ClinicalTrials.gov Identifier: NCT01969513. Retrospectively registered.

BACKGROUND Sexual violence against women occurs worldwide. Prevention programs that treat men as “allies” and integrate a bystander framework are emerging in lower-income settings but evidence of effectiveness is conflicting. OBJECTIVE We tested the impact of GlobalConsent on sexually violent behavior and prosocial bystander behavior among university men in Vietnam. METHODS We applied a double-blind, parallel intervention-versus-control-group design with 1:1 randomization in two universities. Consenting heterosexual or bisexual men 18-24 years and matriculating in September 2019 (n=793) were enrolled and assigned randomly to GlobalConsent or AHEAD. GlobalConsent is an adapted, theory-based, six-module web-based intervention with diverse behavioral-change techniques and a locally produced serial drama. AHEAD is a customized, six-module attention-control program on adolescent health. Both programs were delivered to computers and smartphones over 12 weeks. Sexually violent behaviors toward women in the prior six months and prosocial bystander behaviors in the prior year were measured at zero, six, and 12 months. RESULTS Over 91% of men in both study arms completed at least one program module, and over 88% completed all six modules. At baseline, notable percentages of men reported any sexually violent behavior (GlobalConsent: 31.06%, n=396, AHEAD: 25.94%, n=397) in the prior six months. At endline (posttests 1 and 2 combined) compared to baseline, men receiving GlobalConsent had 1.26 times the odds of reporting a high level (at least two acts) of sexually violent behavior, and 0.67 times the odds of reporting any bystander behavior. The corresponding odds ratios for the AHEAD peers were less favorable, 2.67 and 0.45. CONCLUSIONS Compared to a health attention-control condition, GlobalConsent has sustained favorable impacts on sexually violent behavior and prosocial bystander behavior among matriculating university men in Vietnam, who otherwise would face increasing risks of sexually violent behavior. GlobalConsent shows promise for national scale-up and regional adaptation. CLINICALTRIAL ClinicalTrials.gov NCT04147455

Background There is increasing evidence to support the use of anesthetics to affect operative fields during endoscopic sinus surgery and thus the speed, thoroughness, and safety of the surgery itself. Previous research has suggested preoperative beta-blockers improve surgical fields (SFs); our study is novel in showing the impact of a beta-blocker infusion on SFs during sinus surgery. Methods A prospective, randomized, double-blind, placebo-controlled trial was conducted in 40 patients. Patients undergoing endoscopic sinus surgery for chronic rhinosinusitis received a constant infusion of i.v. esmolol or saline in addition to a standard inhaled anesthetic protocol. At regular 15-minutes intervals, the quality of SF, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were assessed. Total blood loss was also recorded. Results Average vital sign parameters (HR/SBP/DBP) were significantly lower in the esmolol group (69.1/90.2/55.1 versus 77.2/99.5/63.5; p < 0.01). The esmolol infusion improved SFs relative to control (2.3 versus 2.6; p = 0.045). Esmolol infusion resulted in good SFs (grades 1 and 2) more often than poor fields (grades 3 and 4); on the contrary, the control group showed more poor than good SFs (chi-square; p = 0.04). A correlation between increasing HR and worsening SFs was identified (r = 0.259; p = 0.002). The control group had significantly higher average blood loss (1.3 versus 0.8 mL/min; p = 0.037). Conclusion Esmolol-induced relative hypotension and bradycardia during endoscopic sinus surgery achieves significantly improved SFs relative to saline control.

Background.Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) causes skin and soft-tissue infection (SSTI) in military recruits.Objective.To evaluate the effectiveness of 2% Chlorhexidine gluconate (CHG)-impregnated cloths in reducing rates of SSTI and S. aureus colonization among military recruits.Design.A cluster-randomized (by platoon), double-blind, controlled effectiveness trial.Setting.Marine Officer Candidate School, Quantico, Virginia, 2007.Participants.Military recruits.Intervention.Application of CHG-impregnated or control (Comfort Bath; Sage) cloths applied over entire body thrice weekly.Measurements.Recruits were monitored daily for SSTI. Baseline and serial nasal and/or axillary swabs were collected to assess S. aureus colonization.Results.Of 1,562 subjects enrolled, 781 (from 23 platoons) underwent CHG-impregnated cloth application and 781 (from 21 platoons) underwent control cloth application. The rate of compliance (defined as application of 50% or more of wipes) at 2 weeks was similar (CHG group, 63%; control group, 67%) and decreased over the 6-week period. The mean 6-week SSTI rate in the CHG-impregnated cloth group was 0.094, compared with 0.071 in the control group (analysis of variance model rate difference, 0.025 ± 0.016; P = .14). At baseline, 43% of subjects were colonized with methicillin-susceptible S. aureus (MSSA), and 2.1% were colonized with MRSA. The mean incidence of colonization with MSSA was 50% and 61% (P = .026) and with MRSA was 2.6% and 6.0% (P = .034) for the CHG-impregnated and control cloth groups, respectively.Conclusions.CHG-impregnated cloths applied thrice weekly did not reduce rates of SSTI among recruits. S. aureus colonization rates increased in both groups but to a lesser extent in those assigned to the CHG-impregnated cloth Intervention. Antecedent S. aureus colonization was not a risk factor for SSTI. Additional studies are needed to identify effective measures for preventing SSTI among military recruits.Clinical Trials Registration.ClinicalTrials.gov identifier: NCT00475930.

Background. Emotional and psychological effects following abortion are more common than physical side effects and can range from mild regret to more serious complications such as depression. In the last decade, it has been suggested that low dose of ketamine is a fast-acting antidepressant. Purpose. The aim of this study was to investigate the impact of intraoperative ketamine infusion on postoperative mood score in patients undergoing Dilation and Curettage (D&C) under spinal anesthesia. We hypothesized that a single low-dose administration of ketamine infusion during D&C surgery can improve mood scores in the immediate postoperative period. Methods. A prospective, randomized, double-blind, parallel-group, placebo-controlled trial. The study included a total of 60 patients, ≥18 years, physical status ASA II, with up to 12-week gestation undergoing elective D&C surgery. Patients were divided randomly into a ketamine group (group K) and a control group (group C). In group K, 0.4 mg/kg ketamine was given as a continuous infusion over 20 min intraoperatively. Main Outcome Measure. Profile of Mood States (POMS) was recorded preoperatively and 2 hours postoperatively. Results. There were no differences in preoperative POMS between the two groups. Mean postoperative POMS of group K was lower than that of group C indicating mood improvement. Ketamine group patients showed higher sedation score and increased, although self-limiting, psychedelic phenomena than the control group. Conclusion. Observed data here support an acute effect of ketamine on mood but any further claim will be speculative. Further future studies exploring postoperative mood scores after 24 hours post-infusion are needed. This trial is registered with PACTR201907779292947.

Abstract Background Althaea Officinalis introduced as an emerging anti-inflammatory agent with immunomodulatory effects that may suppress the symptoms of atopic eczema. In this study, we aimed to investigate the impact of liposomal formulation of Althaea Officinalis flower extract compared with steroids for atopic eczema treatment. Methods In this randomized, double-blind controlled trial phase II, forty patients with moderate to severe allergic atopic eczema confirmed by skin prick test were enrolled in the study from October 2018 to January 2019. Steroids on the lesions of the left side of the body and topical Althaea Officinalis extract (intervention) or eucerin as a topical placebo on the lesions of the right side of the body were tested. SCORAD (SCORing Atopic Dermatitis) was assessed at the baseline, and two, and four weeks after completing the trial. Data were analyzed by SPSS version 22. Results In the active treatment group, after two weeks, the SCORAD was significantly lower in the left side (recovery with steroid treatment) (p < 0.001), and after 4 weeks the SCORAD was lower on both sides, and there were no significant differences between two sides (similarity between Althaea Officinalis and steroid effects). In the control group, the SCORAD score was significantly lower on the left side (steroid) after two and four weeks (p < 0.001). There was no side effect and reaction to drugs. Conclusions Considering the potential side effects of steroids, and the similar efficacy of Althaea Officinalis flower extract, using this component may be accompanied by higher benefits in patients with atopic eczema.

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Poor quality complementary foods contribute to undernutrition in children aged 6-23 months. Therefore, there is need to explore foods that will provide adequate nutrients for this age group. This study aimed at determining the impact of a sorghum-amaranth composite flour porridge on nutrient intake of children aged 6-23 months. A randomized controlled trial was conducted at Kiandutu slum, Thika, Kenya. Children in the control group (CG), received a maize-sorghum flour while those in the treatment group (TG) received an amaranth-sorghum flour. The sample size per study group was 73 mother-child pairs. The children in the TG received Kcal 1000 worth of porridge/day while those in the CG received Kcal 266.8/day. Mothers of children in both groups were given nutrition education at baseline, and monthly, for six months. Food intake data was taken at baseline, then monthly for six months. Descriptive statistics were used to describe nutrient intake. Chi square and Mann Whitney U test were was used to compare the baseline characteristics of the two groups and their nutrient intake, respectively. At baseline characteristics of the two groups were similar. On a monthly basis, nutrient intake in the TG was significantly higher for a majority of the nutrients than in the CG. The product can contribute to preventing under-nutrition in children aged 6-23 months.

Objective To evaluate the effectiveness of cognitive training in improving tinnitus bother and to identify predictors of patient response. Study Design Prospective open-label randomized controlled trial. Setting Online. Methods Participants were adults with subjective idiopathic nonpulsatile tinnitus causing significant tinnitus-related distress. The intervention group trained by using auditory-intensive exercises for 20 minutes per day, 5 days per week, for 8 weeks. The active control group trained on the same schedule with non–auditory intensive games. Surveys were completed at baseline, 8 weeks, and 12 weeks. Results A total of 64 participants completed the study. The median age was 63 years (range, 25-69) in the intervention group and 61 years (34-68) in the control group. Mixed model analysis revealed that within-subject change in Tinnitus Functional Index in the intervention group was not different than the control group, with marginal mean differences (95% CI): 0.24 (–11.20 to 10.7) and 2.17 (–8.50 to 12.83) at 8 weeks and 2.33 (–8.6 to 13.3) and 3.36 (–7.91 to 14.6) at 12 weeks, respectively. When the 2 study groups were compared, the control group had higher Tinnitus Functional Index scores than the intervention group by 10.5 points at baseline (95% CI, –0.92 to 29.89), 8.1 at 8 weeks (95% CI, –3.27 to 19.42), and 9.4 at 12 weeks (95% CI, –2.45 to 21.34). Conclusion Auditory-intensive cognitive training was not associated with changes in self-reported tinnitus bother. Given the potential for neuroplasticity to affect tinnitus, we believe that future studies on cognitive training for tinnitus remain relevant.
