Background: Sink drainage systems are a potential reservoir for the dissemination of gram-negative bacilli but are not amenable to standard methods of cleaning and disinfection. Pouring liquid disinfectants down drains has only a limited and transient effect on drain colonization, presumably due to inadequate disinfectant contact time and suboptimal penetration into areas harboring biofilm-associated organisms. Methods: We compared the antimicrobial efficacy of 2 novel sink disinfection methods intended to enhance disinfectant contact time and penetration. Healthcare facility sinks were randomly assigned to disinfection with 300 mL hydrogen peroxide-based disinfectant applied either as a foam (N = 13 sinks) or instilled for 30 minutes behind a temporary obstruction created by an inflated urinary catheter balloon (N = 12 sinks). Swabs were used to collect quantitative cultures from the proximal sink drain to depth of 2.5 cm (1 inch) below the strainer before treatment and at 15 minutes and 1, 2, 3, 5, and 7 days after treatment. Repeated measures analysis of variance was performed to compare the efficacy of the 2 treatments. Results: As shown in Fig. 1, both methods yielded an initial reduction of >3 log10 CFU of gram-negative bacilli. Over the 7-day follow-up period, disinfectant instillation resulted in significantly greater reduction than the foam application (P < .01). Recovery of sink colonization to >2 log per swab occurred at day 3 for both treatments, whereas recovery to >3 log per swab occurred on day 3 for the foam treatment versus day 7 for disinfectant instillation. Conclusions: Two novel disinfection methods were effective in reducing sink drain colonization for several days. The instillation method was more effective than the foam method in maintaining reductions over 7 days.Funding: NoneDisclosures: NoneDisclosures: NoneFunding: None

Summary Background Cervical headgear (CH) is a commonly used orthodontic appliance and its dentoalveolar changes are known. However, the effects related to gender and timing have gained less attention. Objectives To examine dimensions of dental arches among children with Class II occlusion without posterior mandibular rotation according to timing of Kloehn-type CH treatment. Trial design Prospective, randomized, parallel-group controlled trial. Methods Sixty-seven seven-year-old children with a Class II occlusion were included in the study. The children were randomized into two equal-size groups in 1:1 ratio by sealed-envelope randomization. The early group (EG, n = 33) was treated between T0 and T1 (26 months), right after eruption of the first maxillary molars. The late group (LG, n = 34) was treated between T1 and T2 (24 months). The children were treated with CH until normal Class I occlusion on first molars was achieved. Impressions for dental casts were taken from all participants at T0, T1, and T2. Blinding was applicable for outcome assessors. Changes in dental cast measurements were compared between the groups and genders using t-test, Mann-Whitney U-test, and repeated measures analysis of variance. Results Of the children, 56 completed the study. The maxillary arch length and the transversal changes between the upper canines and upper first molars were significantly increased in EG at T0−T1 (P < 0.001). At T2, the transversal dimension between the upper first molars was larger (P < 0.05), and in the lower arch the mandibular arch length (P < 0.05) and the transversal dimension between the lower first molars (P < 0.01) were increased in EG males compared to LG males. No harms were encountered. Conclusions The male gender benefits most from early timing of the CH treatment, showing larger dimensions at the end of the follow-up. The results clearly indicated a wider and longer upper dental arch and spontaneous expansion of the lower dental arch after treatment. Clinical Registration NCT02010346.

ABSTRACT Objectives: To investigate the treatment efficacy and follow-up stability of the asymmetric Forsus appliance by evaluating longitudinal changes in dental arch asymmetry on digital dental models from 21 patients. Materials and Methods: Maxillary and mandibular reference lines were used for measurements of intra-arch asymmetry at pretreatment (T1), posttreatment (T2), and 4.2 years after treatment (T3). Maxillary and mandibular measurements were performed relative to the dental midline and anterior reference line on digital dental models. To determine the amount of asymmetry between the Class I and Class II sides of a given arch, all maxillary and mandibular parameters were measured on each side of the model separately. Repeated-measures analysis of variance/paired sample t-tests were performed to evaluate dental arch asymmetries at the P &lt; .05 level. Results: The alveolar transverse dimensions of the posterior segment of both arches were increased during treatment (P &lt; .05) and remained stable during the retention period. Class II subdivision malocclusion was caused by distal positioning of the mandibular canine, premolars, and first molar on the Class II side (P &lt; .05). Asymmetry was resolved by treatment with asymmetric Forsus appliances. The resolved asymmetry remained stable over the long term. There were no significant differences between T2 and T3 (P &gt; .05). Conclusions: The asymmetric Forsus appliance can be used to treat dental arch asymmetry in patients with Class II subdivision malocclusions.

Purposes: This research aims to report the results of a 4-month follow-up study of an expanded cognitive stimulation therapy (CST) group that combines CST and Tai Chi on improving the cognitive abilities of community-dwelling Chinese elderly with mild-stage dementia (EwMD). Methods: Two-group pretest–posttest design was adopted in this study, involving 101 Chinese community-dwelling EwMD who had completed an expanded CST group conducted at a local elderly center. Cognitive abilities of the EwMD were assessed by standardized assessment tools at pretreatment (T1), posttreatment (T2), and the 4-month point after completion of treatment (T3). Results: The repeated-measures analysis of variance showed that after completing the expanded CST group, the improved cognitive abilities of participants could be maintained up to 4 months after the completion of treatment. Conclusions: This study demonstrated that treatment effects of the expanded CST group could be maintained up to 4 months after completion of treatment.

SUMMARY Objective: This clinical study evaluated the color longevity after 30 months of at-home bleaching with 10% carbamide peroxide (CP) in smokers and nonsmokers. Methods: Sixty patients, 30 smokers and 30 nonsmokers, were subjected to bleaching with 10% CP (Whiteness Perfect–FGM) for three hours daily for three weeks. The color was measured at baseline and at one month and 30 months after the completion of dental bleaching using the shade guide Vita classical organized by value (ΔSGU) and the shade guide Vita Bleachedguide 3D-MASTER. At the 30-month recall, the color was assessed before and after dental prophylaxis. Data from color evaluation were analyzed by two-way repeated-measures analysis of variance and Tukey test for the contrast of means (α=0.05). Results: Twenty-one smokers and 22 nonsmokers attended the 30 month recall. For both shade guides, only the main factor of assessment time was statistically significant (p&lt;0.001). Effective whitening was observed in both groups at the baseline, which was stable at one month. However, color rebound was observed after 30 months for both groups of participants when color was measured before and after dental prophylaxis. Conclusion: Thirty months after at-home bleaching with 10% CP gel, dental darkening was detected in both groups, which cannot be solely attributed to stains caused by extrinsic staining from daily food, drinks, and smoke (in smokers).

Objective The aim of this study was to explore variables associated with poor recovery from depression. Method A sample of depressive patients (n = 121) referred to treatment was followed prospectively for 6 years. Clinical evaluations were done at baseline and at 6 month, 1, 2 and 6 years study visits. A diagnosis of major depression based on SCID interview at 6 year and high BDI score along follow-up indicated poor recovery. A diagnosis of full remission at 6 year and low BDI score during follow-up indicated good recovery. Results Chronic depression was found in 15% of patients. A repeated measures analysis of variance of HDRS-, SCL-90, hopelessness (HS) and Social and Occupational Functioning Assessment Scale (SOFAS) scores showed that those with poor recovery had recovered poorly also according these scales during the whole follow-up. Treatment factors did not associate with recovery. Logistic regression analyses revealed an independent association between poor recovery at 6 year and both high HS- and low SOFAS scores at 12 months, 24 months and 6 year assessments. Conclusions Assessment of hopelessness and social and occupational functioning help to early identify high-risk patients who would be in need for more individually tailored treatments.

Objective: We evaluated learning retention in interns exposed to simulation. It was hypothesized that learning would degrade after 6 months and there would be a difference in retention between interns who played a critical role versus those who did not. Methods: A total of 23 groups of 5 to 9 interns underwent a cardiac scenario twice during 1 simulation experience and again 6 months later. We captured 69 recordings (23 before debrief at baseline [PrDV], 23 after debrief at baseline [PoDV], and 23 at 6-month follow-up [FUV]). Students were assigned different roles, including the critical role of “doctor” in a blinded, haphazard fashion. At 6-month follow-up, 12 interns who played the role of doctor initially were assigned that role again, while 11 interns who played noncritical roles initially were newly assigned to doctor. All videos of intern performance were scored independently and in a blinded fashion, by 3 judges using a 15-item check list. Results: Repeated-measures analysis of variance for interns completing all 3 time points indicated a significant difference between time points (F2,22 = 112, p = .00). Contrasts showed a statistically significant difference between PrDV and PoDV (p = .00), and PrDV and FUV (p = .00), but no difference between PoDV and FUV (p = .98). This was consistent with results including all data points. Checklist scores were more than double for PoDV recordings (16) and FUV (15), compared to PrDV recordings (6.6). Follow-up scores comparing old to new doctors showed no statistically significant difference (15.4 vs 15.2 respectively, t21 = 0.26, p = .80, d = .11). Conclusions: Learning retention was maintained regardless of role.

ObjectiveTo assess the risk of disease reactivation during pregnancy after natalizumab suspension in women with multiple sclerosis (MS).MethodsData of all pregnancies occurring between 2009 and 2015 in patients with MS treated with natalizumab and referring to 19 participating sites were collected and compared with those of pregnancies in untreated patients and patients treated with injectable immunomodulatory agents through a 2-factor repeated measures analysis. Predictors of disease activity were assessed through stepwise multivariable logistic regression models.ResultsA total of 92 pregnancies were tracked in 83 women receiving natalizumab. Among these pregnancies, 74 in 70 women resulted in live births, with a postpartum follow-up of at least 1 year, and were compared with 350 previously published pregnancies. Relapse rate during and after pregnancy was higher in women treated with natalizumab (p < 0.001). In multivariable analysis, longer natalizumab washout period was the only predictor of relapse occurrence during pregnancy (p = 0.001). Relapses in the postpartum year were related to relapses during pregnancy (p = 0.019) and early reintroduction of disease-modifying drugs (DMD; p = 0.021). Disability progression occurred in 16.2% of patients and was reduced by early reintroduction of DMD (p = 0.024).ConclusionsTaken as a whole, our findings indicate that the combination of avoiding natalizumab washout and the early resumption of DMD after delivery could be the best option in the perspective of maternal risk. This approach must take into account possible fetal risks that need to be discussed with the mother and require further investigation.Classification of evidenceThis study provides Class IV evidence that in women with MS, the risk of relapses during pregnancy is higher in those who had been using natalizumab as compared to those who had been using interferon-β or no treatment.

Purpose. To evaluate the efficacy and safety of conbercept for patients with chronic central serous chorioretinopathy (CSC). Methods. A retrospective clinical study. Thirty-one patients (35 eyes) with chronic CSC were given intravitreal injections of conbercept and followed up for at least 6 months. Observed indicators included best-corrected visual acuity (BCVA), central macular thickness (CMT), and resolution of subretinal fluid (SRF). Serial changes in BCVA and CMT were analyzed by using repeated measures analysis of variance. Results. During the 6-month follow-up, the mean number of injections required and performed was 1.77 ± 0.60. The logMAR BCVA was 0.48 ± 0.26 at the baseline, 0.34 ± 0.26, 0.30 ± 0.26, 0.27 ± 0.26, 0.24 ± 0.26, and 0.23 ± 0.26 at 2-week and 1-, 2-, 3-, and 6-month follow-ups, respectively (F = 27.173, P<0.05). CMT was 313.74 ± 144.51 μm at the baseline and decreased to 263.49 ± 120.44 μm, 225.91 ± 91.98 μm, 195.77 ± 66.69 μm, 189.74 ± 65.41 μm, and 199.49 ± 81.50 μm at 2-week and 1-, 2-, 3-, and 6-month follow-ups, respectively (F = 18.093, P<0.05). Full resolution of SRF was achieved in 8 (22.9%) eyes at 1 month, 16 (45.7%) eyes at 2 months, 22 (62.9%) eyes at 3 months, and 27 (77.1%) eyes at 6 months after the initial treatment of anti-VEGF injection. No severe adverse event was noted relevant to the therapy. Conclusions. Intravitreal injection of conbercept may effectively reduce the CMT and improve the BCVA in chronic CSC in a short term of 6 months.

Background: Home-based rehabilitation (HBR) was previously found to be associated with positive outcomes that are equal to inpatient rehabilitation. Few studies have examined the challenges patients are facing during rehabilitation and recovery and their satisfaction from HBR. Objective: The purpose of this study was to examine the overall satisfaction and reported outcomes of HBR. Methods: A telephone survey was conducted among 146 orthopedic surgery patients who participated in an HBR program, at the end of the HBR and 6 months after. The questionnaire included information about level of independence, satisfaction from HBR, and difficulties during HBR. Findings: The overall satisfaction was high (73.1%). Patients reported on improvements in level of independence between the time of hospital discharge, the end of the program ( P = .0001), and the 6 months follow-up ( P = .004). Long wait for beginning of HBR, being a widower, and residing in a facility or with a nonfamilial caregiver were associated significantly with less general well-being and independence. The repeated measures analysis showed age lower than 71 and private health insurance ownership were associated with a better recovery. The most common difficulties reported were physical difficulties, lack of function, and caregivers’ burden. Conclusions: Patients and families need more emotional, social, and physical support during HBR. The increase in health services delivered in community settings requires a more clear-cut policy and supervision for HBR and the follow-up services.

ABSTRACT Objectives To evaluate the stability of maxillary interincisor diastema closure and the relationship between space relapse and interincisor diastema width, overjet, overbite, angulations between adjacent maxillary anterior teeth and presence of intermaxillary osseous cleft after orthodontic treatment with extractions. Materials and Methods Twenty-four individuals with a maxillary interincisor diastema pretreatment, treated with maxillary first premolar extractions were evaluated. Dental casts and panoramic radiographs taken at pretreatment (T1), posttreatment (T2), and posttreatment follow-up (T3) were assessed. Periapical radiographs at T1 and T2 were also evaluated. Diastema relapse was assumed when T3-T2 interincisor space change was greater than zero. Diastema relapse was considered clinically significant when it was at least 0.50 mm. Data were analyzed using repeated-measures analysis of variance followed by post hoc Tukey tests or Friedman followed by Wilcoxon tests. T-test or Mann-Whitney U-test, Pearson correlation coefficient, and multiple linear regression analyses were also performed. Results No statistically significant relapse of maxillary interincisor diastemas was found. The percentage of clinically significant relapse of the maxillary interincisor diastemas was 27.78%. Specifically, for the interincisor midline diastema, it was 8.33%. Conclusions Maxillary interincisor diastema closure showed no statistically significant relapse after orthodontic treatment with premolar extractions. Clinically significant stability for maxillary interincisor diastema closure was 72.22% and, specifically, for interincisor midline diastema closure, it was 91.67%.
