Background: Virtual reality (VR) offers much potential for learning, but it challenges learners' orientation. Objectives: This paper investigates whether it is possible to use light or movement cues to facilitate orientation in a search task in a desktop‐VR environment so that participants can better attend to the learning content presented simultaneously. Methods: In two pre‐registered online experiments, we investigated the effects of cueing (light and movement) on search time, learning, and several evaluation variables. Participants were asked to find tools in a virtual workshop, while information about the respective tool was narrated. Experiment 1 (N = 60) used a within‐subject design, that is, the objects were alternately highlighted by light, movement or not. For Experiment 2 (N = 159) the narration was substantially shortened, and a between‐subject design was used. Cognitive load and presence were measured additionally. Results and conclusions: In Experiment 1, only the movement cue decreased search time, indicating automatic guidance of learners' attention. There was no effect of cueing on learning, which may be due to the average search time being substantially shorter than the narration, leaving sufficient time to attend to the narration exclusively. In Experiment 2 search times were significantly faster for both cueing methods, but only the light cue resulted in better learning outcomes, which could be explained by the slightly lower presence in the movement cue condition. Implications: Results imply that it is important to develop cues that automatically guide attention without reducing presence. Lay Description: What is already known about this topic: Virtual reality (VR) offers a lot of opportunities for the integration of educational scenarios.VR is challenging for learners with regard to orientation in a 360° environment.Regarding learning outcomes, research on the effects of cues to highlight important content in a 360° environment is still rare.Presence, defined as the feeling of being there in a VR environment, is an important prerequisite for learning in VR. What this paper adds: The influence of light and movement cues on search times and learning outcomes in a desktop‐VR environment was tested.Movement cues can reliably reduce search times (indicating successful orientation), whereas light cues only reduced search times in predictable scenarios.In a predictable scenario, light cues enhanced learning outcomes compared with movement cues.Movement cues reduced presence, which is one potential reason why movement cues did not improve learning. Implications for practice and/or policy: Using light cues might assist orientation and enhance overall performance in predictable scenarios (i.e., when learners know what kind of cue to expect).In an unpredictable setting with variable cues, light cues did not facilitate orientation, whereas movement cues did.However, movement cues reduced presence, which may have negatively affected learning outcomes. It is important to develop cueing methods that also work in more unpredictable settings, but that do not reduce presence. [ABSTRACT FROM AUTHOR]

Background Study: The effects of the flipped classroom (FC) on students' academic performance remain ambiguous, and the use of pre‐class videos may be one of the main factors hindering students' progress. A software package called GeoGebra has been proposed as a substitute for pre‐class videos to aid students' learning. Objective: This study investigates the effect of the FC using GeoGebra (FCG) on mathematical performance and memory among senior secondary students. Methods: One hundred and sixty students of a senior high school in China were selected. A quasi‐experimental design was implemented in which the classes were split into the intervention group (FCG), control group A (FCV) and control group B (TL) by random assignment. Pretest, Post‐test 1 and Post‐test 2 were introduced. Results and Conclusion: The results indicate that both the FCG and the FC with pre‐class videos (FCV) were more effective than traditional lectures in enhancing students' academic test scores, and that the effect of the FCG was comparable to its video counterpart, F(2, 136) = 3.752, ρ = 0.026, η2 = 0.052. Although their effects were similar, the qualitative results revealed some hidden benefits associated with the replacement of pre‐class video with GeoGebra. Furthermore, although they were equally effective in promoting students' performance in the short‐term, the long‐term effects on academic performance of both forms of FC were non‐significant when compared with traditional lectures. Lay Description: What is already known about this topic: Flipped classroom is an effective strategy in teaching mathematics.Among those challenges, video may be one of the main factors hindering the effect of flipped classroom. What this paper adds: GeoGebra could be an effective alternative to video.Effect between the flipped classroom using GeoGebra and the flipped classroom using video were similar.Both the flipped classroom with GeoGebra and the flipped classroom with videos were more effective than traditional lectures. Implications for practice and/or policy: Students' short‐term performance could be enhanced by visualisation provided by flipped classroom.To enhance students' long‐term performance, an appropriate amount of homework is suggested.

Background: A total of 68% of pre‐school children with cleft palate have speech problems requiring speech therapy. There is a lack of access to regular targeted therapy. Parent training leads to positive outcomes in early communication skills in cleft palate and non‐cleft speech disorders. Connected health has been used to address inadequate access to therapy, providing intervention to those who would not otherwise receive therapy. Aims: To evaluate the speech, activity and participation outcomes of Parent Led, Therapist Supervised, Articulation Therapy (PLAT) compared with routine speech therapy intervention in parent–child dyads. Methods & Procedures: A total of 44 children, aged 2.9–7.5 years, were included in a two‐centre, two‐phase randomized controlled trial. Informed consent and assent were obtained. Participants and speech and language therapists (SLTs) were unblinded to the groups. Parents, in the parent‐trained group (n = 23), attended 2 days' training, received a detailed speech therapy programme, and undertook intervention over 12 weeks supported by the cleft specialist SLT using FaceTime and one face‐to‐face session. In the control arm (n = 21), parent–child dyads received six therapy sessions over 12 weeks with a research SLT, comparable with usual care. Speech recordings were undertaken pre‐ and post‐intervention. Percent consonant correct (PCC) was analysed by external SLTs blinded to the time and group. Activity and participation were measured using the Intelligibility in Context Scale (ICS) and Focus on Outcomes for Children Under Six (FOCUS) questionnaire. Outcomes & Results: There was no evidence of an interaction between Time and Group or an overall statistical difference between groups for PCC scores. There was a statistically significant difference over time for both groups (words: p < 0.002; confidence interval (CI) = 9.38–16.27; d = 0.57; sentences: p < 0.002; CI = 16.04–25.97; d = 0.23). Effect sizes were medium for words and small for sentences. For intelligibility and participation, there was no evidence of an interaction between Time and Group or an overall statistical difference between groups. A statistically significant difference over time was found for intelligibility (F = 29.97, d.f. = 1, 42, p < 0.001, 95 % CI = 1.45–3.15 d = 0.46) and for participation (F = 14.19, d.f. = 1, 41, p < 0.001 95% CI = 7.63–25.03; d = 0.36) with FOCUS results indicating clinically meaningful (parent‐led group) and significant (control group) change in participation. Conclusions & Implications: PLAT can be as effective as routine care in changing speech, activity and participation outcomes for children with cleft palate, when supported by a specialist cleft SLT using connected health. What this paper addsWhat is already known on this subjectOver 50% of children with cleft palate require speech therapy. However, there is a lack of timely, accessible speech therapy services in the UK and Ireland. Previous studies have shown that parents can deliver therapy effectively, and that connected health can support the delivery of speech therapy. This study aims to provide evidence that parent‐led therapy with the supervision of a specialist cleft therapist using FaceTime is effective.What this paper adds to existing knowledgeThis randomized controlled trial indicates that parents can be trained to deliver therapy for children with cleft palate speech disorders, under the supervision of an SLT. This approach results in improved speech, activity and participation outcomes similar to routine care.What are the potential or actual clinical implications of this work?This study indicates that both parent‐led articulation therapy and routine care showed meaningful gains in speech, activity and participation, and that parent‐led articulation therapy when supported by a cleft SLT using connected health could be an additional service delivery model for children with cleft palate speech disorders.

Background: Performance monitoring plays a key role in self‐regulated learning, but is difficult, especially for complex visual tasks such as navigational map reading. Gaze displays (i.e. visualizations of participants' eye movements during a task) might serve as feedback to improve students' performance monitoring. Objectives: We hypothesized that participants who review their performance based on screen recordings that also display their gaze would have a higher monitoring accuracy and increase in post‐test performance and would remember more executed actions than participants who review based on a screen recording only (i.e. control condition). Methods: Sixty‐four higher education students were randomly assigned to a gaze‐display or control condition. After watching an instruction video, they practiced five navigational map‐reading tasks and then reviewed their performance while thinking aloud, either prompted by a screen recording with gaze display or a screen recording only. Before and after reviewing, participants estimated the number of correctly solved tasks and finally made a five‐item post‐test. Results and conclusions: Analyses with frequentist and Bayesian statistics showed that gaze displays did not improve monitoring accuracy (i.e. estimated minus actual performance), post‐test performance, or the number of reported actions. It is concluded that scanpath gaze displays do not provide useful cues to improve monitoring accuracy in this task. Takeaways: Gaze displays are a promising tool for education, but scanpath gaze displays did not help to enhance monitoring accuracy in a navigational map‐reading task. Lay description: What is currently known?: Monitoring performance is central in self‐regulated learning.Monitoring is often difficult for learners, in particular in complex visual tasks.Gaze displays visualize viewing behaviour that was measured with eye tracking.Gaze displays can improve task performance, but effects on monitoring are unknown. What does the paper add?: We expected gaze displays to help learners to monitor their performance on a map‐reading task.However, dynamic gaze displays did not help to improve monitoring accuracy in this study.Further research should investigate whether other types of gaze displays improve monitoring. Implications for practitioners: Eye tracking provides promising ways to support monitoring and learning.However, not all forms of using gaze displays enhance monitoring or learning.The specific implementation of gaze displays might matter.

Objectives: The aim of the current study was to investigate the robustness of the human movement effect and its stability over time by comparing the effectiveness of dynamic and static presentations on acquisition and retention of a gross motor skill. Methods: One hundred and seven first‐year students studying for the certificate in Physical Education course were randomly divided into three groups: (i) static pictures (N = 32), (ii) enriched static pictures with arrows (N = 34), and (iii) video (N = 41). They were instructed to observe the demonstration of the Ippon‐Seoi‐Nage (a Judo technique) and reproduce it during the acquisition phase or after a delay of 1 week during the retention phase. Results and Conclusions: The results showed that enriched static pictures (with arrows) resulted in more efficient learning than the static pictures (without arrows). Most importantly, it was shown that learners receiving the video presentation outperformed learners receiving the static presentations, with regard to acquisition and retention, indicating therefore a robust human movement effect. Implications: These findings provide confirmation of the superiority of video presentations for teaching and learning motor skills involving the entire human body. Lay Description: What is already known about this topic:External visualizations are broadly used in Physical education (PE) and sport context.Static visualizations are regarded as the fundamental tools used by PE teachers to communicate visual information that is difficult to verbally describe.Increasing use of dynamic visualizations such as videos largely supplanted the use of static pictures in PE contextWhat this paper adds:Comparing the effectiveness of static pictures and digital videos in tactical learningExploring the human movement effect and its stability over timeImplications for practice and/or policy:The human movement effect is a robust phenomenon not only when it is evaluated immediately after the learning phase but also after a notable delay.Dynamic visualizations remain the most powerful computer‐based technique by which people can learn complex motor skills.

Introduction: Occupational therapy often involves handwriting acquisition practices that include the non‐dominant hand when improvements in the dominant hand function are not possible because of trauma or stroke. This study explored whether character tracing and using a pegboard can effectively improve the handwriting of the non‐dominant hand. Methods: A randomised controlled trial involving 60 healthy university students aged ≥18 years was conducted. Participants were randomly assigned to the writing group, peg group or control group. The character recognition rate was evaluated by computer software. Furthermore, character quality and writing speed were evaluated by humans using global legibility scales. Evaluations were performed before the intervention (baseline) and on days 5 and 10 of the intervention. Using the non‐dominant hand, the writing group traced characters on paper with a ballpoint pen, and the peg group used a pegboard for 15 min/day for 10 days. Results: Compared with the peg and control groups, the writing group showed significant improvements in the character recognition rate and global legibility scale score. However, the global legibility scale score did not improve to the same level as that achieved with the dominant hand. None of the evaluation scores of the peg group showed significant improvements compared with those of the control group. There were no significant differences in improvements in the writing speed of the writing and peg groups compared with the control group. Conclusion: Tracing characters can improve the handwriting ability of the non‐dominant hand, but using a pegboard may be less effective. Future research is needed to examine how much practice is necessary to improve the handwriting ability of the non‐dominant hand sufficiently. [ABSTRACT FROM AUTHOR]

Background: Many people with aphasia have word‐finding difficulties, with some showing particular difficulties with verbs. Picture‐naming therapy is often used to improve naming, but gains are usually limited to therapy items and do not transfer to conversation. Therapy where words are produced in sentences and in real‐life activities may be more effective. Aims: The current pilot study investigated whether an activity‐oriented therapy approach would be accepted and viable if implemented in a community setting, and whether communicating whilst cooking was more beneficial than using paper‐based activities. If successful, it would be expected that verb production would improve in structured and unstructured tasks in both naming and narrative tasks. Methods & Procedures: The study employed a case‐series repeated‐measures design, with testing of treated and control items. Seven adults with anomia participated, although only five completed the full programme. Participants were divided into two groups and each group completed both treatments, but in different orders. Each treatment was employed for six 2‐h sessions over a 3‐week period. Outcomes & Results: Naming of both treated and untreated verbs showed a statistically significant improvement following both treatments and this continued into the maintenance phase. There was a numerical but not statistically significant gain in the variety of verbs used in spoken narratives. Participants predominantly chose positive terms to describe their experience of the programme, but did not prefer one therapy over the other. Conclusions & Implications: Preliminary findings suggest that an activity‐oriented therapy approach, whether it involves carrying out tasks or paper‐based activities, can result in clinically meaningful improvements for people with chronic aphasia. Further research using a randomized control trial is required to determine whether cooking therapy alone is effective. [ABSTRACT FROM AUTHOR]

Prenatal iron supplementation improves children's health and cognitive performance, but few studies explore behavioural development. This study assessed the effects of adjusting prenatal iron supplementation to maternal iron stores during early pregnancy on children's behavioural problems. Randomized controlled trial conducted in Tarragona (Spain) involving 230 nonanaemic pregnant women and their children after a 4‐year follow‐up. Based on haemoglobin (Hb) levels before gestational week (GW) 12, women receive different iron doses: those with Hb = 110–130 g/L were randomized to receive 80 or 40 mg/day and those with Hb > 130 g/L were randomized to receive 20 or 40 mg/day. Maternal iron stores at GW12 were classified using serum ferritin (SF) as low (SF < 15 µg/L), normal (SF = 15–65 µg/L), and normal‐high (SF > 65 µg/L). Children's behaviour was assessed by parents using the Child Behaviour Checklist for ages 1.5–5 years and the Behaviour Rating Inventory of Executive Function‐Preschool Version, and by teachers using the Teacher's Report Form for ages 1.5–5 years. Multivariable regression models were performed. Taking 80 mg/day of iron improved child behaviour when women had low iron stores but worsened it when mothers had normal–high iron stores, except for depressive and attention/hyperactivity problems. Taking 20 mg/day of iron improved behaviour only in those children whose mothers had SF > 65 µg/L in early pregnancy. Additionally, executive functioning improved at high doses of prenatal iron when maternal baseline SF < 15 µg/L. Adjusting prenatal iron supplementation to both maternal baseline Hb levels and iron stores reduces behavioural problems in 4‐year‐old children. Key messages: Prenatal iron supplementation succeeds in improving maternal haematological outcomes and cognitive performance of children, but few studies have focused on behavioural development.Prenatal iron supplementation adjusted to maternal iron stores reduces behavioural problems in 4‐year‐old children.Maternal iron stores early in pregnancy should be measured in addition to haemoglobin concentration.These findings contribute greatly to the advancement of public health by giving physicians the tools to prescribe the most appropriate dose of iron supplementation to contribute to better child development.

Background/aim Engagement in desired occupations can promote health and wellbeing in older adults. Assessments of engagement often measure frequency, amount or importance of specific activities. This study aimed to develop a scale to measure older adults' evaluation of the extent to which their everyday activities are contributing to their health and wellness. Methods Eighteen items, each scored with a seven-point rating scale, were initially developed by content experts, covering perceptions of how daily activities contribute to physical and mental health, as well as satisfaction and activity participation in the last six months. Rasch analysis methods were used to refine the scale using the pencil and paper responses of 460 community-living older adults. Results Initial Rasch analysis indicated three unlabelled rating scale categories were seldom used, reducing measurement precision. Five items were conceptually different by misfit statistics and principal component analysis. Subsequently, those items were removed and the number of rating scale steps reduced to 4. The remaining 13-item, 4-step scale, termed the Activity Significance Personal Evaluation ( ASPEn), formed a unidimensional hierarchy with good fit statistics and targeting. Person separation reliability (2.7) and internal consistency (.91) indicated the tool is appropriate for individual person measurement. Relative validity indicated equivalence between Rasch measures and total raw scores. Conclusions ASPEn is a brief, easily administered assessment of older adults' perception of the contribution of everyday activities to personal health and wellness. ASPEn may facilitate occupational therapy practice by enabling clinicians to assess change in meaning of an older adult's activity over time. [ABSTRACT FROM AUTHOR]

Aim: The aim of the present study was to compare performance 5 h after a 90‐min endurance training session when either carbohydrate only or carbohydrate with added whey hydrolysate or whey isolate was ingested during the first 2 h of the recovery period. Methods: Thirteen highly trained competitive male cyclists completed three exercise and diet interventions (double‐blinded, randomized, crossover design) separated by 1 week. The 90‐min morning session (EX1) included a 60 min time‐trial (TT60). Immediately and 1 h after exercise, participants ingested either (1) 1.2 g carbohydrate∙kg−1∙h−1 (CHO), (2) 0.8 g carbohydrate∙kg−1∙h−1 + 0.4 g isolate whey protein∙kg−1∙h−1 (ISO) or (3) 0.8 g carbohydrate∙kg−1∙h−1 + 0.4 g hydrolysate whey protein∙kg−1∙h−1 (HYD). Additional intakes were identical between interventions. After 5 h of recovery, participants completed a time‐trial performance (TTP) during which a specific amount of work was performed. Blood and urine were collected throughout the day. Results: TTP did not differ significantly between dietary interventions (CHO: 43:54 ± 1:36, ISO: 46:55 ± 2:32, HYD: 44:31 ± 2:01 min). Nitrogen balance during CHO was lower than ISO (p < 0.0001) and HYD (p < 0.0001), with no difference between ISO and HYD (p = 0.317). In recovery, the area under the curve for blood glucose was higher in CHO compared to ISO and HYD. HR, VO2, RER, glucose, and lactate during EX2 were similar between interventions. Conclusion: Performance did not differ after 5 h of recovery whether carbohydrate only or isocaloric carbohydrate plus protein was ingested during the first 2 h. Correspondingly, participants were not in negative nitrogen balance in any dietary intervention. [ABSTRACT FROM AUTHOR]

Aims: Determine efficacy of "KARER" educational intervention on caring ability and burden of caregiving relatives of disabled patients with stroke and cardiovascular diseases. Design: Clinical, randomized, controlled and double blinded trial with a mixed approach. Methods: Study population will be made up of 96 caregiving relatives of patients of home‐hospitalized care programs in the cities of Bogotá and Bucaramanga, (Colombia), between March 2021 and March 2022. Participants will be randomly assigned into two groups, either intervention (n = 48) or control (n = 48). The intervention is interdisciplinary and multi‐component: B‐Learning modality and clinical simulation. Follow‐up of participants will last 8 weeks from intervention period start‐out, and measurements will be taken and analysed in masked form. The main results will be the mean score changes of care ability and caregiver burden. Discussion: Caregiving relatives will show better adaptation to their role through effective use of caring abilities as they look after disabled persons with chronic diseases. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to compare the efficacy of e‐flipped and online case‐based workshops on the nurses' knowledge, attitude and behaviour regarding thalassemia during the COVID‐19 pandemic. Design: A pre‐test–posttest interventional study was conducted with two intervention groups and a control group. Methods: One hundred and fifty nurses were recruited from comprehensive urban health centres in June–December 2020. The nurses were randomly allocated to one of the three groups: case‐based e‐flipped workshop (n = 50), case‐based online workshop (n = 50) and control (n = 50). A researcher‐made questionnaire was completed by eligible subjects at baseline, after the end of the training sessions and 4 weeks after interventions to assess their knowledge, attitude and behaviour. Data were analysed in IBM SPSS v16.0. ANOVA and Tukey's post hoc tests were used to compare the three groups. Results: The mean knowledge, attitude and behaviour scores in the intervention groups increased significantly more than that in the control group (p <.001). One week and 4 weeks following the intervention, the mean score of knowledge, attitude and behaviour in the e‐flipped group was greater than that in the online group (p <.001). According to the results, e‐flipped and online case‐based workshops can improve nurses' knowledge, attitude and behaviour regarding thalassemia. [ABSTRACT FROM AUTHOR]

Background: Sleep disturbance negatively affects recovery and survival of patients in intensive care units (ICUs). Aims and Objectives: This study aimed to measure the noise levels and evaluate the impact of a white noise app on the sleep quality of critically ill patients. Design: A quasi‐experimental time series pre‐test–post‐test control group design with repeated measures was adopted. Methods: The study was conducted in the high dependency unit (HDU) of a selected tertiary care hospital in Mangalore, Karnataka State, India. Conscious oriented patients with systolic blood pressure ranging from 100/70 to 140/90 mm Hg and hearing acuity of at most 20 dB in both ears were included in the study. Noise levels in the HDU were measured using calibrated sound level meter on weekdays/weekends in three different shifts and an average of 24 readings was obtained per shift. A 4‐point Likert scale was used to assess the sleep quality. The intervention included administration of white noise app twice a day, for three consecutive days by using different masking sounds such as white noise on day 1 which resembles to a humming AC conditioner, pink noise on day 2 which resembles to the sound of ocean waves and brown noise on day 3 which resembles a steady rainfall. The app was used with the help of JBL earphones C10SI an excellent noise cancellation and noise isolating earphone. Results: Among the 54 subjects, the mean age of the patients was 40.28 years, majority 34 (63%) were males. The noise level in the ICU was more than 60 dB. There was a significant difference in the sleep quality after the application of the white noise app in the experimental group on Day 1 (Z = −3.996; P =.001), Day 2 (Z = −3.302; P =.001), and Day 3 (−2.822; P =.005) compared to the control group. Conclusion: Adoption of technology driven noise reduction applications would enhance the quality of sleep among the ICU patients. Relevance to clinical practice: The use of a technology‐driven application helps control noise levels which promotes improved sleep quality among critically ill patients in the intensive care units.

Frontal plane postures during the ultimate step of sidestepping are linked to increased anterior cruciate ligament injury risk. However, there is a lack of research detailing the kinematic strategies present in the penultimate step. This study, therefore, investigated penultimate and ultimate step kinematics of planned sidestepping (pSS) and unplanned sidestepping (upSS) to further understand the effect of planning time on known ultimate step kinematic and kinetic differences. Sixty male amateur Australian Rules football players performed three trials of straight‐line running (RUN), pSS, and upSS in a randomized order. Mediolateral foot placement and three‐dimensional joint kinematics for the knee, pelvis, and trunk were measured at final foot contact of the penultimate step and initial foot contact of the ultimate step. Peak knee moments were measured during the weight acceptance phase of the ultimate step. In pSS, at the penultimate step final foot contact, the support foot was placed across the midline of the center of mass, in the frontal plane, contralateral to the sidestep direction. Greater trunk lateral flexion toward the sidestep direction and greater negative pelvic lateral tilt were observed in pSS compared with upSS and RUN. Differences between pSS and upSS frontal plane kinematics at penultimate step final foot contact suggest preparatory reorientation strategies are likely constrained by the amount of planning time available. As there are clear differences in preparatory kinematics, we recommend that planning time be considered when training and assessing sidestepping maneuvers and planned and unplanned maneuvers not be treated as interchangeable skills.

Objective: To participate in shared decision making (SDM), patients need to understand their options and develop trust in their own decision‐making abilities. Two experiments investigated the potential of decision aids (DAs) in preparing patients for SDM by raising awareness of preference‐sensitivity (Study 1) and showing possible personal motives for decision making (Study 2) in addition to providing information about the treatment options. Methods: Participants (Study 1: N = 117; Study 2: N = 217) were put into two scenarios (Study 1: cruciate ligament rupture; Study 2: contraception), watched a consultation video and were randomized into one of three groups where they received additional information in the form of (a) narrative patient testimonials; (b) non‐narrative decision strategies; and (c) an unrelated text (control group). Results: Participants who viewed the patient testimonials or decision strategies felt better prepared for a decision (Study 1: P <.001, ηP2 = 0.43; Study 2: P <.001, ηP2 = 0.57) and evaluated the decision‐making process more positively (Study 2: P <.001, ηP2 = 0.13) than participants in the control condition. Decision certainty (Study 1: P <.001, ηP2 = 0.05) and satisfaction (Study 1: P <.001, ηP2 = 0.11; Study 2: P =.003, d = 0.29) were higher across all conditions after watching the consultation video, and certainty and satisfaction were lower in the control condition (Study 2: P <.001, ηP2 = 0.05). Discussion: Decision aids that explain preference‐sensitivity and personal motives can be beneficial for improving people's feelings of being prepared and their perception of the decision‐making process. To reach decision certainty and satisfaction, being well informed of one's options is particularly relevant. We discuss the implications of our findings for future research and the design of DAs.

Objectives: To compare 3 mouthwashes: 0.20% chlorhexidine (CHX) with Anti‐Discoloration System (ADS), 0.20% CHX and 0.12% CHX with 0.05% cetylpyridinium chloride (CPC), in terms of reduction of plaque and gingival bleeding and side effects. Methods: Mild gingivitis patients were randomly divided into three Groups: they underwent professional oral hygiene and received instructions: oral rinse with 10 mL for 1', twice a day, 30' after tooth brushing, for 14 days. Primary outcomes were plaque and gingival bleeding, assessed with Plaque Control Record and Gingival Bleeding Index. Feedback questionnaire and spectrophotometer evaluated secondary outcomes: adverse events. Timing of the study was T0 (baseline), T1 (professional oral hygiene) and T2 (14th day after mouthwash use). Results: Sixty‐six patients were recruited, two patients dropped out, and 64 patients completed the study. PCR T1‐T2 mean variation was 30.67 (SD = 15.22; 95% CI 23.55 to 37.80; P = 0.000), 19.93 (SD = 11.03; 95% CI 14.90 to 24.95; P = 0.000) and 16.24 (SD = 15.35; 95% CI 9.60 to 22.88; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. GBI mean variation (T0‐T2) was −9.82 (SD = 9.27; 95% CI −5.48 to 14.16; P = 0.000), −19.31 (SD = 11.33; 95% CI −14.15 to −24.47; P = 0.000) and −21.13 (SD = 12.56; 95% CI −15.70 to −26.56; P = 0.000) respectively in Groups 0.2% CHX + ADS, 0.2% CHX and 0.12% CHX + CPC. Statistical significance was found in lower efficacy of 0.2% CHX + ADS Group. Patients tolerated 0.12% CHX + CPC mouthwash better in bleeding perception (95.5%; P = 0.046), burning sensation (13.6%; P = 0.006), and mouthwash taste (100%; P = 0.000). Results on staining were no statistically significant (P = 0.106). Conclusions: Addition of CPC allows reduction of CHX percentage in mouthwash formulation while keeping equal efficacy and less side effects. ADS addition decreases CHX efficacy in reducing plaque and bleeding, while resulting more tolerated than CHX. [ABSTRACT FROM AUTHOR]

Study design This single-masked, randomized and six-month clinical intervention trial including two study groups was planned to evaluate the efficacy of maintenance treatment with glycine powder on the periodontal health of peri-implant tissues. Methods A total of 46 patients with partial or total edentulism, carrying a total of 88 implants, were assigned either to an air abrasive with the glycine powder treatment group ( AAD) or to a manual debridement and clorexidine administration treatment group ( MDA). Clinical data were collected before treatment and at 3 and 6 months after the treatment. Plaque index ( PI), bleeding index ( BOP), probing depth ( PD), clinical attachment level ( CAL) and bleeding score ( BS) were analysed. Results After 3 months, AAD treatment statistically significantly improved BS ( P < 0.05); at 6 months, AAD treatment statistically significantly improved indexes PD, PI, BOP and BS ( P < 0.05). In addition, the AAD treatment proved to be more effective than MDA in maintaining the peri-implant health of PD at three and 6 months, and of PI at 6 months ( P < 0.05). There were no significant changes of CAL in both groups, and all the indexes remained within the physiological levels. Conclusions Within the limits of the study, treatment with glycine seems appropriate in the maintenance of peri-implant health and more effective than the traditional treatment with plastic curette and chlorhexidine.

Prenatal supplementation with protein-energy (PE) and/or multiple-micronutrients (MMNs) may improve fetal growth, but trials of lipid-based nutritional supplements (LNSs) have reported inconsistent results. We conducted a post-hoc analysis of non-primary outcomes in a trial in Gambia, with the aim to test the associations of LNS with fetal growth and explore how efficacy varies depending on nutritional status. The sample comprised 620 pregnant women in an individually randomized, partially blinded trial with four arms: (a) iron and folic acid (FeFol) tablet (usual care, referent group), (b) MMN tablet, (c) PE LNS, and (d) PE + MMN LNS. Analysis of variance examined unadjusted differences in fetal biometry z-scores at 20 and 30 weeks and neonatal anthropometry z-scores, while regression tested for modification of intervention-outcome associations by season and maternal height, body mass index, and weight gain. Despite evidence of between-arm differences in some fetal biometry, z-scores at birth were not greater in the intervention arms than the FeFol arm (e.g., birth weight z-scores: FeFol −0.71, MMN −0.63, PE −0.64, PE + MMN −0.62; group-wise p = .796). In regression analyses, intervention associations with birth weight and head circumference were modified by maternal weight gain between booking and 30 weeks gestation (e.g., PE + MMN associations with birth weight were +0.462 z-scores (95% CI [0.097, 0.826]) in the highest quartile of weight gain but -0.099 z-scores (−0.459, 0.260) in the lowest). In conclusion, we found no strong evidence that a prenatal LNS intervention was associated with better fetal growth in the whole sample. [ABSTRACT FROM AUTHOR]

Background: Postnatal maternal depressive symptoms are consistently associated with reduced quality of mother- infant interaction. However, there is little research examining the role of maternal cognitive factors (e.g. rumination) in the relationship between depressive symptoms and mother-infant interaction quality. This study investigated the hypotheses that: dysphoric mothers would demonstrate less sensitive behaviour towards their infants compared with nondysphoric mothers; mothers induced to ruminate would be less sensitive towards infants; rumination would moderate the relationship between maternal depressive symptoms and maternal sensitivity and the impact of the rumination induction would increase following a stressor (still face) task. Method: Mothers (N = 79; 39 dysphoric and 40 nondysphoric) and their infants were randomised to either a rumination induction or a control condition. Maternal sensitivity in mother-infant interactions was assessed before and after the induction using the CARE Index. In the second interaction task, mothers also completed the still-face procedure as a stressor. Results: Extending previous research, mixed measures ANOVAs demonstrated that dysphoric mothers had reduced quality of interaction with their infant compared with nondysphoric mothers and that mothers in the rumination condition exhibited reduced sensitivity towards their infants relative to mothers in the control condition. Further, maternal sensitivity worsened further after the still-face procedure in the rumination condition, but not in the control condition. Conclusions: This study suggests that the repetitive, internal focus of a ruminative state is causally implicated in mother-infant interaction quality, regardless of the level of depressive symptoms. This research extends understanding of specific mechanisms involved in the quality of the mother-infant relationship. [ABSTRACT FROM AUTHOR]

ABSTRACT Aim This study aimed to investigate the effects of a peer education on cardiac self-efficacy ( CSE) and readmission of the patients undergoing bypass surgery. Background Self-efficacy is an antecedent vital factor in both initiating and maintaining healthy behaviours. It significantly improves after effects of heart attacks, anxiety and diminishes the possibility of readmission. Design This study is a randomized-controlled trial. Method Sixty patients undergoing bypass surgery were chosen and assigned equally into the control and intervention groups. While routine education was presented to the patients in the control group, intervention group were taught using the peer education in two sessions. CSE of all the selected patients was assessed orderly in 5 days, 4 weeks and 8 months after surgery. Moreover, their readmission was investigated after 8 months from surgery. Data was collected using demographic and the CSE scale. Data were also analysed by using χ2, Kolmogorov-Smirnov and repeated measures analysis of variance tests. Results The mean score of CSE in the intervention group was significantly different from the corresponding number in the control group in all three stages of data collecting ( p < 0·001). Compared to the control group, a smaller number of the patients in the intervention group were readmitted to the hospitals after 8 months ( p = 0·011). Conclusions Implementation of peer education has positive effects on CSE in patients who have bypass surgery and reduces their hospital readmission. It can be beneficial to apply this method as an educative-supportive approach in cardiac surgery fields. Relevance to clinical practice Implementation of peer education has positive effects on CSE in these patients and reduces their hospital readmission. [ABSTRACT FROM AUTHOR]

Aim To investigate the clinical and microbiological effects of local disinfection with 0.5% sodium hypochlorite (NaOCl) with or without systemic antimicrobials (amoxicillin and metronidazole, AM) during basic periodontal therapy (BPT). Material and Methods In a randomized clinical trial (four groups), 110 chronic periodontitis patients received BPT plus local irrigation with saline (BPT + S), local disinfection with NaOCl (BPT + DIS), BPT + DIS + AM or BPT + S + AM. The outcome was analysed at baseline, 3, 6 and 12 months. Results There was no difference in clinical attachment level gain at 12 months between the four groups. BPT + DIS showed no additional improvement compared to BPT + S; BPT + DIS + AM showed fewer sites with probing pocket depth (PPD) ≥7 mm versus BPT + S only up to 6 months ( p = 0.037). In factorial analyses, additional clinical reduction for PPD ( p = 0.023) and number of sites with PPD ≥5 ( p = 0.007), ≥6 ( p = 0.002) and ≥7 mm ( p < 0.001) were found when AM was added to BPT, but not when DIS was applied. In all groups, a comparable decrease in targeted bacteria was found. AM caused adverse events in 22% of the patients. Conclusion Local disinfection with NaOCl, also in combination with AM, showed, after 1-year follow-up, no additional clinical and microbiological effects compared to BPT alone.

Background Exercise under hypoxic conditions represents an additional stress in relation to exercise in normoxia. Hypoxia induces oxidative stress and inflammation as mediated through tumour necrosis factor ( TNF)-α release that might be exacerbated through exercise. In addition, vitamin E supplementation might attenuate oxidative stress and inflammation resulting from hypoxia during exercise. The present study aimed to evaluate the effects of vitamin E supplementation (250 mg) on inflammatory parameters and cellular damage after exercise under hypoxia simulating an altitude of 4200 m. Methods Nine volunteers performed three sessions of 60 min of exercise (70% maximal oxygen uptake) interspersed for 1 week under normoxia, hypoxia and hypoxia after vitamin E supplementation 1 h before exercise. Blood was collected before, immediately after and at 1 h after exercise to measure inflammatory parameters and cell damage. Results Percentage oxygen saturation of haemoglobin decreased after exercise and recovered 1 h later in the hypoxia + vitamin condition ( P < 0.05). Supplementation decreased creatine kinase (CK)-TOTAL, CK-MB and lactate dehydrogenase 1 h after exercise ( P < 0.05). The exercise in hypoxia increased interleukin (IL)-6, TNF-α, IL-1ra and IL-10 immediately after exercise ( P < 0.05). Supplementation reversed the changes observed after exercise in hypoxia without supplementation ( P < 0.05). Conclusions We conclude that 250 mg of vitamin E supplementation at 1 h before exercise reduces cell damage markers after exercise in hypoxia and changes the concentration of cytokines, suggesting a possible protective effect against inflammation induced by hypoxia during exercise.

Aims To examine the safety and effectiveness of buprenorphine + naloxone sublingual tablets (BUP, as Suboxone®) provided after administration of extended-release injectable naltrexone (XR-NTX, as Vivitrol®) to reduce cocaine use in participants who met DSM-IV criteria for cocaine dependence and past or current opioid dependence or abuse. Methods This multi-centered, double-blind, placebo-controlled study, conducted under the auspices of the National Drug Abuse Treatment Clinical Trials Network, randomly assigned 302 participants at sites in California, Oregon, Washington, Colorado, Texas, Georgia, Ohio, New York and Washington DC, USA to one of three conditions provided with XR-NTX: 4 mg/day BUP (BUP4, n = 100), 16 mg/day BUP (BUP16, n = 100, or no buprenorphine (placebo; PLB, n = 102). Participants received pharmacotherapy for 8 weeks, with three clinic visits per week. Cognitive behavioral therapy was provided weekly. Follow-up assessments occurred at 1 and 3 months post-intervention. The planned primary outcome was urine drug screen (UDS)-corrected, self-reported cocaine use during the last 4 weeks of treatment. Planned secondary analyses assessed cocaine use by UDS, medication adherence, retention and adverse events. Results No group differences were found between groups for the primary outcome (BUP4 versus PLB, P = 0.262; BUP16 versus PLB, P = 0.185). Longitudinal analysis of UDS data during the evaluation period using generalized linear mixed equations found a statistically significant difference between BUP16 and PLB [ P = 0.022, odds ratio (OR) = 1.71] but not for BUP4 ( P = 0.105, OR = 1.05). No secondary outcome differences across groups were found for adherence, retention or adverse events. Conclusions Buprenorphine + naloxone, used in combination with naltrexone, may be associated with reductions in cocaine use among people who meet DSM-IV criteria for cocaine dependence and past or current opioid dependence or abuse.

Objectives To compare the use of sonic powered or manual toothbrush in patients with intellectual disability ( ID) in terms of plaque (PlI) and gingival ( GI) indices and adverse effects. Material and Methods Subjects with ID were recruited for this cluster-randomized, single blinded (examiner), 6-month clinical trial, comparing powered versus manual toothbrushing. Outcome variables included PlI and GI, evaluated at baseline and 3 months after supervised toothbrushing and after 3 additional months of unsupervised used. Clinical outcome variables were analysed by repeated measures ANCOVA considering time and group as factors and respective baseline values as covariates (generalized linear model). Results Sixty-four patients (34 male, mean age 34.5) in six clusters were included in the study. No statistically significant effect of toothbrushing group was observed for PlI or GI. A significant effect of time was identified ( p < 0.001) with mean reductions ranging 0.44-0.45 for PlI and 0.30-0.36 for GI from baseline to 3-6 months. No relevant adverse effect or technical problems were observed. Conclusion The tested sonic powered toothbrush was as effective and safe as the manual toothbrush. The use of powered or manual toothbrushes, together with fluoride toothpaste, may improve plaque and gingivitis levels, in patients with mild to limit ID. [ABSTRACT FROM AUTHOR]

Dialectical behaviour therapy (DBT)-informed skills training for borderline personality disorder (BPD) aims at the development of specific emotion regulation skills in patients, particularly with regard to the regulation of problematic anger. While the effects of dialectical behaviour skills training have been shown, their processes of change are rarely examined. Neacsiu, Rizvi and Linehan (2010) found that patient's self-reported use of emotion regulation skills was a mediator of therapeutic change in these treatments; however, they found no effect for problematic anger. From an integrative perspective on anger (Pascual-Leone & Greenberg, 2007; Pascual-Leone & Paivio, 2013), there are several forms of anger, varying in their degree of therapeutic productivity. The present add-on randomized controlled trial included n = 41 patients with BPD ( n = 21 DBT-informed skills training versus n = 20 treatment as usual). The first study examined the outcome of the DBT-informed skills training encompassing basic components of training in mindfulness, distress tolerance, interpersonal effectiveness and emotion regulation. Results showed that symptom reduction was significantly greater in the DBT-informed skills training, compared with the treatment as usual. The second study used process assessment, for which all patient completers underwent a 50-min-long psychological interview both early and late in treatment, which was rated using the Classification of Affective Meaning States. DBT-informed skills training produced increased levels of primary 'assertive' anger, as compared with the treatment as usual, whereas no effect was found for 'rejecting' secondary anger. Most importantly, we showed that changes in assertive anger mediated the reported symptom reduction, in particular in patient's social roles. We discuss these results in the context of underlying mechanisms of change in DBT skills group treatments, in particular towards developing more productive forms of anger in this patient population. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message A 20-session dialectical behaviour therapy (DBT)-informed skills training is a promising adjunct intervention for patients with borderline personality disorder, in particular for reducing problems related to social role., Increases in assertive anger mediate the effects of DBT-informed skills training, whereas rejecting anger remains unchanged over the course of treatment., Short-term objectives for intervention might involve the specific increase of assertive anger in BPD, by using DBT-informed skills training; long-term objectives for intervention might involve a specific decrease of rejecting anger in BPD.

Objective Evaluate the immediate and cumulative optical whitening efficacy of a blue covarine toothpaste. Materials and Methods 180 bovine tooth specimens with similar shade (Δ E < 3.5) were staining of different beverage: black tea(BT), green tea (GT), red wine (RW), orange soda (OS), and brazilian açai juice (AJ), and then submitted to tooth brushing with a blue covarine toothpaste (Op) or a control abrasive toothpaste (Ab). The whitening effect was evaluated at baseline (B), after staining (S), after 1 day (1D) and 7 days of cumulative use of toothpastes (7D). The color shade chances were assessment by Vita Easyshade reflectance spectroscope and the data of CIELab color coordinates (L*, a*, and b*), color difference (Δ E) and the whiteness index optimized (WIO), were analyzed by two-way mixed analysis of variance (ANOVA) for repeated measures and Bonferroni-corrected t-tests (α = 0.05). Results The analysis showed statistically significant differences before and after staining by colored beverages ( p < 0.05), but no differences were found due to the action of toothpaste ( p > 0.05), in the CIELab coordinates, Δ E and WIO index. Conclusions The use of toothpastes (Op or Ab) reduced the dental staining caused by different colored beverage, but the whitening effect of blue covarine toothpaste could not be confirmed ( p > 0.05).

Background An increased plasma lipopolysaccharide ( LPS) concentration may favour metabolic disorders such as insulin resistance. The meal composition influences plasma LPS concentrations. The present study aimed to investigate the effect of the acute consumption of a high-fat meal (49% of energy from fat) containing conventional or high-oleic peanuts on post-prandial LPS concentrations and its relationship with lipaemia and insulinaemia in overweight and obese men. Methods The test meal consisted of a shake containing conventional peanuts ( CVP; n = 21), high-oleic peanuts ( HOP; n = 23) or a control biscuit ( CT; n = 21). Blood samples were collected in the fasting state and 1, 2 and 3 h post-prandially. LPS, insulin, lipids and glucose concentrations were assessed. Results LPS concentrations were lower in CVP [mean (SE) 0.7 (0.5) EU mL−1] and HOP [1.0 (0.9) EU mL−1] groups compared to CT [1.6 (1.2) EU mL−1] at 3 h post-prandially. Triacylglycerol and insulin concentrations increased in all groups. Triacylglycerol started to increase only after 2 h in the CVP and HOP groups. LPS correlated positively with triacylglycerol. Insulin returned to basal concentrations at 3 h only in the CVP and HOP groups. Conclusions The acute consumption of peanuts delayed the increase in serum triacylglycerol and favoured the quicker return of insulin to basal concentrations, especially in the CVP group. Our results suggest that the consumption of conventional or high-oleic peanuts may help to reduce the risk of endotoxaemia and metabolic disorders. [ABSTRACT FROM AUTHOR]

Background Posttraumatic stress disorder (PTSD) is an important and timely clinical issue particularly for combat veterans. Few pharmacologic options are available to treat PTSD, particularly among military personnel, and they are not based on rational neurobiology. The evidence for noradrenergic dysregulation in PTSD is strong, and the alpha-adrenergic agonist prazosin is one of the most promising medications to treat sleep disturbances associated with PTSD as well as PTSD symptoms among both veterans and civilians. Evidence also implicates noradrenergic dysregulation in the pathophysiology of alcohol dependence (AD); prazosin also may have efficacy in treating this disorder. The use of prazosin represents a rational and compelling approach for the treatment of PTSD and comorbid AD. Given the high rates of comorbid AD in trauma survivors with PTSD, and the enormous impact that these comorbid disorders have on psychosocial function and well-being, finding effective treatments for this population is of high clinical importance. Methods Ninety-six veterans with PTSD and comorbid AD were randomized to receive prazosin (16 mg) or placebo in an outpatient, randomized, double-blind, clinical trial for 13 weeks. Main outcomes included symptoms of PTSD, sleep disturbances, and alcohol use. Results Symptoms of PTSD improved over time, but contrary to the hypothesis, there was no medication effect on PTSD symptoms, or on sleep. Alcohol consumption also decreased over time, but there were no significant differences in outcomes between medication groups. Conclusions Prazosin was not effective in treating PTSD symptoms, improving sleep, or reducing alcohol consumption overall in this dually diagnosed group. This does not support the use of prazosin in an actively drinking population and suggests that the presence of a comorbid condition affects the efficacy of this medication. This study highlights the importance of conducting clinical trials in 'real-world' patients, as results may vary based on comorbid conditions. [ABSTRACT FROM AUTHOR]

Background and Objectives The aim of this study was, first, to investigate the effect of omega 3 (ω3) fatty acids plus low-dose aspirin with closed debridement in the treatment of patients with periodontitis and type 2 diabetes mellitus (DM), and second, to estimate the expression of monocyte chemoattractant protein-3 (MCP-3) in response to the supposed modulatory therapy. Material and Methods Forty patients with chronic periodontitis and type 2 DM were equally divided into groups 1 (patients received ω3 plus low-dose aspirin for 6 mo) and 2 (patients received placebo during the same period). Evaluation was done clinically (pocket depth, clinical attachment loss, gingival index and plaque index) and biochemically by estimating levels of interleukin 1β and MCP-3 in gingival crevicular fluid, plus investigating the effect of treatment on glycemic control by levels of glycated hemoglobin A1c in serum. All data were collected at baseline, 3 and 6 mo after treatment. Results Subjects of group 1 showed a highly significant reduction in pocket depth, clinical attachment loss, gingival index ( p ≤ 0.01) after 3 and 6 mo compared to group 2. Glycated hemoglobin A1c levels showed a reduction in both groups at the end of the study period, with a non-significant difference ( p > 0.05). Furthermore, the treatment protocol showed a significant reduction in levels of MCP-3 and interleukin 1β at 3 and 6 mo compared to the placebo group. Conclusions Within the limits of the present study, ω3 plus low-dose aspirin proved effective as an adjunct to closed periodontal therapy in the management of patients with periodontitis and type 2 DM. Moreover, MCP-3 was proven to be effective both in the pathogenesis of the disease and as a biomarker in evaluating the response to periodontal treatment. [ABSTRACT FROM AUTHOR]

Background Adequately developed fundamental movement skills, particularly object control dimensions, are considered essential to learn more complex movement patterns and to increase the likelihood to successfully participate in organized and non-organized sports during later years. Thus, the present randomized controlled trial aimed at improving object control dimensions at an early state in a kindergarten setting. Methods Catching, throwing, kicking, rolling and stationary dribbling were assessed via gross motor development 2 (TGMD-2) testing in 41 normally developed preschoolers. On a cluster-randomized basis [strata: age, sex and body mass index (BMI)], three kindergartens were randomly assigned to an intervention group (n = 22, INT, age: 4.6 ± 1.0 years; BMI: 16.2 ± 1.1 kg/m²) and three to a control group (n = 19,CON: age: 4.5 ± 1.2 years; BMI: 16.8 ± 1.2 kg/m²).Twelve structured training sessions were given within 6 weeks (12 sessions).The total training volume was 330 min. Results Moderate time × group interaction were observed for the total sum score (+22%, P = 0.05) and dribbling (+41%, P = 0.002). Adjusting for baseline differences analyses of covariance did not affect these results. Interestingly, likely to most likely practically worthwhile effects were detected for the total sum score, catching and dribbling. Conclusion Object control dimensions such as dribbling and catching that apparently rely on rhythmical movement patterns and anticipatory eye-hand coordination seem to benefit from short-term object control training. These skills are considered important for successful team-sport participation and appropriate sportive motor development. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Successful prevention of eating disorders represents an important goal due to damaging long-term impacts on health and well-being, modest treatment outcomes, and low treatment seeking among individuals at risk. Mindfulness-based approaches have received early support in the treatment of eating disorders, but have not been evaluated as a prevention strategy. This study aimed to assess the feasibility, acceptability, and efficacy of a novel mindfulness-based intervention for reducing the risk of eating disorders among adolescent females, under both optimal (trained facilitator) and task-shifted (non-expert facilitator) conditions. Method A school-based cluster randomized controlled trial was conducted in which 19 classes of adolescent girls ( N = 347) were allocated to a three-session mindfulness-based intervention, dissonance-based intervention, or classes as usual control. A subset of classes ( N = 156) receiving expert facilitation were analyzed separately as a proxy for delivery under optimal conditions. Results Task-shifted facilitation showed no significant intervention effects across outcomes. Under optimal facilitation, students receiving mindfulness demonstrated significant reductions in weight and shape concern, dietary restraint, thin-ideal internalization, eating disorder symptoms, and psychosocial impairment relative to control by 6-month follow-up. Students receiving dissonance showed significant reductions in socio-cultural pressures. There were no statistically significant differences between the two interventions. Moderate intervention acceptability was reported by both students and teaching staff. Discussion Findings show promise for the application of mindfulness in the prevention of eating disorders; however, further work is required to increase both impact and acceptability, and to enable successful outcomes when delivered by less expert providers. © 2015 Wiley Periodicals, Inc.

This study examined the effect of dietary supplementation with inorganic nitrate () on markers of contractile function in human knee extensors. In a double-blinded, randomized cross-over design, 18 (12 M) healthy participants undertook four days of supplementation with either nitrate-rich beetroot juice (NITRATE; days 1–3: 525 mg, day 4: 1050 mg) or nitrate-depleted beetroot juice (PLACEBO). On the fourth day, isometric knee extension force was assessed during a series of voluntary and electrically evoked (stimulation) tests. In addition, muscular fatigue was examined in two separate continuous-stimulation (0.8 s tetanus with a 1:1 work:rest ratio for 102.4 s) fatigue tests, one with and one without blood flow restriction. There were no differences for maximum voluntary contraction, peak twitch force, half-relaxation time and the force–frequency relationship for stimulations up to 100 Hz between the NITRATE and PLACEBO trials. No differences between trials were observed in the non-restricted fatigue test, however NITRATE was found to attenuate the decline in force during the restricted test, such that the force at the 80 s mark (PLACEBO: 66 ± 11 vs. NITRATE 74 ± 9% of initial force;P = .01) and 102 s mark (PLACEBO: 47 ± 8% vs. NITRATE 55 ± 8%;P < .01) were significantly higher. These results suggest that four days ofsupplementation elicits peripheral responses in muscle that attenuate muscular fatigue during exhaustive exercise under hypovolemic conditions. This ergogenic action is likely attributable to improved Ca2+handling in the muscle, or enhanced perfusion during ischemia. [ABSTRACT FROM AUTHOR]

As pregnancy may trigger overweight in women, new means for its prevention are being sought. The aim here was to investigate the effect of individual dietary counselling during and after pregnancy on post‐partum weight and waist circumference up to 4 years post‐partum. A cohort of women (n = 256) were randomized to receive repeated individual dietary counselling by a nutritionist during and after pregnancy, or as controls not receiving dietary counselling, from the first trimester of pregnancy until 6 months after delivery. Counselling aimed to bring dietary intake into line with recommendations, with particular focus on the increase in the intake of unsaturated fatty acids instead of saturated. Pre‐pregnancy weight was taken from welfare clinic records. Weight and waist circumference were measured at 4 years after delivery. The proportion of overweight women increased from 26% prior to pregnancy to 30% at 4 years after delivery among women receiving dietary counselling, as against considerably more, from 32% to 57%, among controls. The prevalence of central adiposity was 31% in women receiving dietary counselling, 64% in controls. Likewise, both the risk of overweight (odds ratio: 0.23, 0.08–0.63, P = 0.005) and central adiposity (odds ratio: 0.18, 0.06–0.52, P = 0.002) were lower in women receiving dietary counselling compared with controls. Repeated dietary counselling initiated in early pregnancy can be beneficial in long‐term weight control after delivery. [ABSTRACT FROM AUTHOR]

Background With rates of autism diagnosis continuing to rise, there is an urgent need for effective and efficient service delivery models. Pivotal Response Treatment ( PRT) is considered an established treatment for autism spectrum disorder ( ASD); however, there have been few well-controlled studies with adequate sample size. The aim of this study was to conduct a randomized controlled trial to evaluate PRT parent training group ( PRTG) for targeting language deficits in young children with ASD. Methods Fifty-three children with autism and significant language delay between 2 and 6 years old were randomized to PRTG ( N = 27) or psychoeducation group ( PEG; N = 26) for 12 weeks. The PRTG taught parents behavioral techniques to facilitate language development. The PEG taught general information about ASD (clinical trial NCT01881750; ). Results Analysis of child utterances during the structured laboratory observation (primary outcome) indicated that, compared with children in the PEG, children in the PRTG demonstrated greater improvement in frequency of utterances ( F(2, 43) = 3.53, p = .038, d = 0.42). Results indicated that parents were able to learn PRT in a group format, as the majority of parents in the PRTG (84%) met fidelity of implementation criteria after 12 weeks. Children also demonstrated greater improvement in adaptive communication skills (Vineland- II) following PRTG and baseline Mullen visual reception scores predicted treatment response to PRTG. Conclusions This is the first randomized controlled trial of group-delivered PRT and one of the largest experimental investigations of the PRT model to date. The findings suggest that specific instruction in PRT results in greater skill acquisition for both parents and children, especially in functional and adaptive communication skills. Further research in PRT is warranted to replicate the observed results and address other core ASD symptoms. [ABSTRACT FROM AUTHOR]

Objectives To investigate the effectiveness of a 6-month Liuzijue qigong ( LQG) program in promoting physical and psychosocial function in individuals with chronic obstructive pulmonary disease ( COPD). Design Single-blind, randomized controlled trial. Setting Seven hospital respiratory care centers in Beijing. Participants Individuals with COPD (N = 126; mean age 71.1 ± 2.7, range 65-85). Methods Participants were randomly assigned to one of two groups: LQG (n = 63) and control (n = 63). Subjects in the LQG group received a LQG program consisting of four 45-minute sessions each week and daily walking for 30 minutes for 6 months. Control subjects walked daily for 30 minutes. Data collection was performed at baseline, at 6 weeks, and at 6 months. Primary outcomes involved functional capacity, and secondary outcomes involved quality of life. Results The LQG group had greater improvements in the 6-minute walk test ( P = .02); specific airway conductance ( P = .02); monitored functional task evaluation ( P = .04); Medical Outcomes Study 36-item Short-Form Health Survey ( SF-36; general health ( P < .001), mental health ( P = .03)); Chronic Respiratory Questionnaire (dyspnea ( P = .05), emotion ( P = .05), and mastery ( P = .04) at 6-month follow-up. After 6 months, the control group had significant improvement only on the SF-36 mental health ( P = .02). Conclusion LQG promoted functional capacity and quality of life in older adults with COPD at 6 months and is a good alternative home exercise program for older adults in the rehabilitation of COPD.

This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups - dental caries treatment (DCT) and caries-free (CF) - according to their caries experience [decayed, missing, or filled primary teeth (dmft) and decayed, missing or filled secondary teeth (DMFT) values of ≥0]. The CPQ8-10 instrument was administered at baseline and at 4 wk of follow-up (i.e. 4 wk after completion of dental treatment). In the DCT group, increases in CPQ8-10 scores were observed between the baseline and follow-up results. However, longitudinal evaluation of the CF group demonstrated no statistically significant difference in CPQ8-10 scores. Responsiveness of the CPQ8-10 instrument (magnitude of change in CPQ8-10 scores) in the DCT group was greater (effect size >0.7) than in the CF group. The findings of this study show that dental caries treatment has an important impact on OHRQoL of children. The CPQ8-10 was considered an acceptable instrument for longitudinal measurement of changes in OHRQoL. [ABSTRACT FROM AUTHOR]

Objectives Treatment failure is a common phenomenon, but little is known about the reasons. Therapeutic alliance, therapist adherence, and therapist competence are considered important aspects of treatment success and formed the focus of the current investigation. Design Three randomized controlled trials for the treatment of depression, social phobia, and hypochondriasis were the basis of the current study. Methods The role of therapeutic alliance, as well as therapist adherence and competence, were investigated in 61 patients, which were classified either as treatment failure or as treatment success. Process variables were evaluated by independent raters on the basis of videotapes of the first three treatment sessions. Results Therapists' adherence and therapeutic alliance differed significantly between successful treatments and those classified as failures, whereas therapists' competence did not. In cross-sectional analysis, we found a moderating effect of adherence with alliance on treatment outcome, indicating that the better the therapeutic alliance, the stronger the effect of adherence on treatment outcome. Moreover, higher therapists' competence was found to affect treatment outcome positively, only mediated by therapeutic alliance. Higher therapists' adherence affected treatment outcome positively, only mediated by the competence-alliance relationship. In additional longitudinal analyses, we found evidence that the therapeutic alliance within one session influences therapists' adherence and competence in the subsequent session, but not the other way around. Conclusions Therapeutic alliance proved to be an important variable for the prediction of treatment failure. Furthermore, in our longitudinal analyses, we found evidence that the therapeutic alliance is a precondition for the adherent and competent implementation of therapeutic techniques, which questions the results of our cross-sectional analysis and of previous research. Practitioner points Clinical implications Treatment failure is associated with a lower therapeutic alliance in cognitive-behavioural treatment., Therapeutic alliance seems to be an important precondition for the adherent and competent implementation of therapeutic techniques., Therapeutic alliance should be monitored during psychotherapeutic treatment., Cautions or limitations Results are limited to cognitive-behavioural therapy and may not be representative for other treatment approaches., Process analyses are based on highly standardized randomized controlled trials and may not be generalizable to routine care.

Xanthine oxidase (XO), a free radical-generating enzyme, is involved in tissue damage produced during exhaustive exercise. Our aim was to test whether allopurinol, a powerful inhibitor of XO, may be effective in preventing exercise-induced tissue damage in soccer players. Twelve soccer players were randomized into two experimental groups. One received allopurinol, before a match of the premier Spanish Football League, and the other placebo. Allopurinol prevented the exercise-induced increase in all the markers of skeletal muscle damage analyzed: creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and myoglobin. Creatine kinase-MB isoenzyme and highly sensitive troponin T, specific biomarkers of myocardial injury, increased significantly in the placebo but not in the allopurinol-treated group after the football match. We also found that the exercise-induced lipid peroxidation, as reflected by malondialdehyde measurements, was prevented after allopurinol administration. However, inhibition of XO did not prevent the increment in the activity of alanine aminotransferase found after the match. No changes in the serum gamma glutamyltransferase activity was found after the match on either the placebo and the allopurinol groups. These two enzymes were determined as biomarkers of liver injury.

Background More conservative techniques for managing dental caries including 'partial' and 'no caries removal' have been increasingly of interest. Aim To compare children's behaviour and pain perception, also technique acceptability (parents and dentists), when approximal dentinal lesions ( ICDAS 3-5) in primary molars (3-8-year-olds) were managed with three treatment strategies; conventional restorations ( CR), hall technique ( HT), and non-restorative caries treatment ( NRCT). Design Secondary care-based, three-arm parallel-group, randomised controlled trial, with 169 participants treated by 12 dentists. Outcome measures: child's pain perception (Visual Analogue Scale of Faces); behaviour (Frankl scale); and parents' and dentists' treatment opinions (5-point Likert scales). Results Children showed more negative behaviour in the CR group (37%) compared to NRCT (21%) and HT (13%) ( P = 0.047, CI = 0.41 to 0.52). Pain intensity was rated 'very low' or 'low' in 88% NRCT, 81% HT, and 72% CR ( P = 0.11, CI = 0.10 to 0.12). NRCT and HT were 'very easy' or 'easy' to perform for >77% of dentists, compared to 50% in CR group ( P < 0.000). There were no statistically significant differences in parents' rating of their child's level of comfort ( P = 0.46, CI = 0.45 to 0.48). Conclusions Dentists reported more negative behaviour in CR group. For all techniques, children's pain perception and dentist/parent acceptability were similar. [ABSTRACT FROM AUTHOR]

Objective To assess the relief of migraine pain, especially in the acute phase, by comparing active treatment, ie, kinetic oscillation stimulation ( KOS) in the nasal cavity, with placebo. Background Exploratory trials testing the efficacy of KOS on migraine patients indicated that this treatment could be a fast-acting remedy for acute migraine pain. Method Thirty-six patients were randomized 1:1 using a placebo module to active or placebo treatment in this double-blinded parallel design study. Treatment was administered with a minimally invasive inflatable tip oscillating catheter. Symptom scores (0-10 visual analog scale) were obtained before treatment, every 5 minutes during treatment, at 15 minutes, 2, and 24 hours post-treatment, as well as daily (0-3 migraine pain scale) from 30 days pretreatment until Day 60 post. Thirty-five patients were evaluated (active n = 18, placebo n = 17). The primary end-point was the change in average pain score from before treatment to 15 minutes after treatment. Results Patients who received active treatment reported reduced pain, eg, average visual analog scale pain scores fell from 5.5 before treatment to 1.2 15 minutes after, while the corresponding scores for recipients of placebo fell from 4.9 to 3.9. The changes in pain scores differed between the 2 treatments by 3.3 points (95% confidence interval: 2.3, 4.4), P < .001. Already 5 minutes into the treatment, the difference (1.9 points) was significant ( P = .007). The difference was likewise significant at 2 hours post-treatment (3.7 points, P < .001). One patient experienced an adverse event (a vasovagal reaction with full spontaneous recovery) during placebo treatment. Conclusion KOS is an effective and safe treatment for acute migraine pain.

Objectives To compare the effects of different types of physical and mental activity on self-reported sleep quality over 12 weeks in older adults with cognitive and sleep complaints. Design Randomized controlled trial. Setting General community. Participants Seventy-two inactive community-dwelling older adults with self-reported sleep and cognitive problems (mean age 73.3 ± 6.1; 60% women). Intervention Random allocation to four arms using a two-by-two factorial design: aerobic+cognitive training, aerobic+educational DVD, stretching+cognitive training, and stretching+educational DVD arms (60 min/d, 3 d/wk for physical and mental activity for 12 weeks). Measurements Change in sleep quality using seven questions from the Sleep Disorders Questionnaire on the 2005 to 2006 National Health and Nutrition Examination Survey (range 0-28, with higher scores reflecting worse sleep quality). Analyses used intention-to-treat methods. Results Sleep quality scores did not differ at baseline, but there was a significant difference between the study arms in change in sleep quality over time ( P < .005). Mean sleep quality scores improved significantly more in the stretching+educational DVD arm (5.1 points) than in the stretching+cognitive training (1.2 points), aerobic+educational DVD (1.1 points), or aerobic+cognitive training (0.25 points) arms (all P < .05, corrected for multiple comparisons). Differences between arms were strongest for waking at night ( P = .02) and taking sleep medications ( P = .004). Conclusion Self-reported sleep quality improved significantly more with low-intensity physical and mental activities than with moderate- or high-intensity activities in older adults with self-reported cognitive and sleep difficulties. Future longer-term studies with objective sleep measures are needed to corroborate these results. [ABSTRACT FROM AUTHOR]

Objectives To determine the effects of tai chi training on functional performance and walking with and without the addition of the performance of a cognitive task, in older adults living in supportive housing facilities. Design Secondary data analysis comparing a single-blind, randomized controlled trial of tai chi training with an attention-matched educational control intervention with crossover to tai chi. Setting Two supportive housing facilities. Participants Sixty-six men and women living in supportive housing facilities entered the study, and 57 aged 87 ± 7 completed all study procedures. Intervention Interventions consisted of two 1-hour-long instructor-led group sessions per week for 12 weeks. Tai chi training consisted of movements based upon the Yang-style short form. Educational sessions consisted of lectures and discussions of age-related health topics. Measurements Subjects were tested for physical function (Short Physical Performance Battery, SPPB), balance (Berg Balance Scale, BBS), mobility (timed up-and-go, TUG), and walking speed under normal and cognitive dual-task conditions. Results The tai chi group exhibited greater improvement in SPPB scores (baseline 8.1 ± 2.9, follow-up 9.0 ± 2.6) than controls (baseline 8.2 ± 2.6, follow-up 8.2 ± 2.6) ( P = .005). Tai chi also increased normal and dual-task walking speed ( P < .001) yet did not affect BBS ( P = .02) or TUG ( P = .02) after accounting for multiple comparisons. The dual-task cost (percentage change) to walking speed was unaffected. After the crossover tai chi intervention, the control group improved performance in the SPPB, BBS, and TUG, and increased walking speed under normal and dual-task conditions ( P = .008). Conclusion Tai chi training may be a safe and effective therapy to help improve physical function and dual-task walking in very old adults living in supportive housing facilities.

What is already known about this subject Obesity-related insulin resistance is highly prevalent in children and adolescents, and contributes to an increased lifetime risk of type 2 diabetes mellitus and cardiovascular disease., Intensive exercise training may improve insulin sensitivity., What this study adds Three monitored exercise training sessions per week for 8 weeks can improve fitness-related insulin sensitivity in obese, insulin resistant children., Insulin sensitivity and skeletal muscle oxidative phosphorylation may be dissociable in this population., Improvements in fitness may be accompanied by a rise in intramyocellular lipid content and an associated increase in resting energy expenditure., Background Obesity is associated with poor fitness and adverse metabolic consequences in children. Objective To investigate how exercise and lifestyle modification may improve fitness and insulin sensitivity in this population. Design and subjects Randomized controlled trial, 21 obese (body mass index ≥ 95% percentile) subjects, ages 10 to 17 years. Methods Subjects were given standardized healthful lifestyle advice for 8 weeks. In addition, they were randomized to an in-home supervised exercise intervention ( n = 10) or control group ( n = 11). Measurements Fasting laboratory studies (insulin, glucose, lipid profile) and assessments of fitness, body composition, skeletal muscle oxidative phosphorylation and intramyocellular lipid content ( IMCL), were performed at baseline and study completion. Results Subjects were 13.0 ± 1.9 (standard deviation) years old, 72% female and 44% non-white. Exercise improved fitness ( P = 0.03) and power ( P = 0.01), and increased IMCL ( P = 0.02). HOMA-IR decreased among all subjects in response to lifestyle modification advice ( P = 0.01), regardless of exercise training assignment. In univariate analysis in all subjects, change in cardiovascular fitness was associated with change in HOMA-IR. In exploratory analyses, increased IMCL was associated with greater resting energy expenditure (r = 0.78, P = 0.005) and a decrease in fasting respiratory quotient (r = −0.70, P = 0.02) ( n = 11). Conclusions Change in fitness was found to be related to change in insulin resistance in response to lifestyle modification and exercise in obese children. IMCL increased with exercise in these obese children, which may reflect greater muscle lipid oxidative capacity. [ABSTRACT FROM AUTHOR]

Objective The purpose of this ongoing randomized study was to assess differences in bone level changes and success rates using implants supporting single crowns in the posterior mandible either with platform matched or platform switched abutments. Material and Methods Patients aged 18 and above, missing at least two teeth in the posterior mandible and with a natural tooth mesial to the most proximal implant site were enrolled. Randomization followed implant placement. Definitive restorations were placed after a minimum transgingival healing period of 8 weeks. Changes in crestal bone level from surgery and loading (baseline) to 12-month post-loading were radiographically measured. Implant survival and success were determined. Results Sixty-eight patients received 74 implants in the platform switching group and 72 in the other one. The difference of mean marginal bone level change from surgery to 12 months was significant between groups ( p < 0.004). Radiographical mean bone gain or no bone loss from loading was noted for 67.1% of the platform switching and 49.2% of the platform matching implants. Implant success rates were 97.3% and 100%, respectively. Conclusions Within the same implant system the platform switching concept showed a positive effect on marginal bone levels when compared with restorations with platform matching.

In randomized controlled trials ( RCTs), with customized structured physical exercise activity ( SPEA) interventions, the dose of leisure-time physical activity ( LTPA) should exceed the LTPA dose of the nonexercising control ( C) group. This increase is required to substantiate health improvements achievable by exercise. We aimed to compare the dose of SPEA, LTPA, and total LTPA ( SPEA + LTPA) between a randomized Nordic walking ( NW) group, a power-type resistance training ( RT) group, and a C group during a 12-week exercise intervention in obese middle-aged men ( n = 144) with impaired glucose regulation. The dose of physical activity was measured with diaries using metabolic equivalents. No significant difference ( P > 0.107) between the groups was found in volume of total LTPA. The volume of LTPA was, however, significantly higher ( P < 0.050) in the C group than in the NW group, but not compared with the RT group. These results indicate that structured exercise does not automatically increase the total LTPA level, possibly, as a result of compensation of LTPA with structured exercise or spontaneous activation of the C group. Thus, the dose of total LTPA and the possible changes in spontaneous LTPA should be taken into account when implementing a RCT design with exercise intervention. [ABSTRACT FROM AUTHOR]

Objective To determine if baseline/interictal saliva calcitonin gene-related peptide ( CGRP) levels would be lower in subjects with chronic migraine receiving onabotulinumtoxin A compared with those receiving saline. Background CGRP is considered central to the pathogenesis of episodic migraine, but its relationship to chronic migraine is less understood. Onabotulinumtoxin A is an effective treatment for chronic migraine and has been demonstrated to inhibit the vesicular release of CGRP. Methods This was an exploratory, randomized, placebo-controlled, crossover pilot study of 20 subjects that received onabotulinumtoxin A and saline injection (placebo). The amount of CGRP in saliva samples collected on a nonheadache or low headache day, and prior to and after treatment of a headache exacerbation was measured. Daily headache records, medications, and response to treatment were recorded in a diary. Results A decrease in baseline/interictal saliva CGRP levels for subjects receiving onabotulinumtoxin A from 39.4 ± 7.5 pg CGRP/mg total protein after the first month to 25.5 ± 4.1 pg after the third month was observed. However, this difference did not reach significance nor was it significant when compared to the saline treatment. There was a reduction in the number of headache days for both onabotulinumtoxin A and saline over baseline throughout the active phases of the study. However, there was no statistical difference in headache days between groups. Subjects with a greater than 50% response to onabotulinumtoxin A had better 2-hour pain relief with acute treatment than non-responders to onabotulinumtoxin A or saline. Conclusion While CGRP levels were not elevated during a migraine attack in chronic migraine subjects as has been reported in episodic migraine, there was an overall decrease in the baseline/interictal levels in response to onabotulinumtoxin A.

Objectives Low-dose stavudine therapy may have a lower toxicity profile compared with standard dose. A randomized controlled trial comparing these two doses of stavudine with tenofovir disoproxil fumarate (tenofovir DF) was performed to assess the effects on anthropometry, markers of inflammation, and lipid and glucose metabolism in Black South African patients. Methods Sixty patients were randomized 1:1:1 to either standard-dose (30-40 mg) or low-dose (20-30 mg) stavudine or tenofovir DF (300 mg), each combined with lamivudine and efavirenz, for 48 weeks. Anthropometry, markers of inflammation, and lipid and glucose metabolism were assessed using standard techniques. Results In all three treatment arms, there was a significant increase in lipid levels over the study period. At 48 weeks, fasting glucose level ( P < 0.005) and homeostasis model assessment ( HOMA) score ( P < 0.05) increased significantly in the standard-dose stavudine arm, as did insulin and C-peptide levels in both the standard- and low-dose stavudine arms. At week 48, a significant decrease ( P < 0.05) in adiponectin was noted in the standard-dose stavudine arm, but there was an increase ( P < 0.005) in the tenofovir DF arm. In both the stavudine arms, significant increases in anthropometric measures occurred at 24 weeks but these decreased by week 48. Mitochondrial toxicities occurred in both the stavudine arms. Immunological and virological outcomes were similar for all three arms. Conclusions This study highlights the occurrence of metabolic abnormalities with both stavudine and tenofovir DF treatment. Awareness of the potential increased cardiovascular risk should be of concern with the use of both these therapies. [ABSTRACT FROM AUTHOR]

Background Modifying the consistency of food and drink is a strategy commonly used in the management of dysphagia for people with intellectual disabilities ( ID). People with ID often depend on others for the preparation of food and drink and therefore depend on those caregivers achieving the correct consistency to keep them safe and avoid discomfort during mealtimes. Clinical experience and prior research have demonstrated that although training can improve modification, carers often find modification difficult and potentially stressful and recommend additional support for carers. Fluid consistency is often modified through the addition of powdered thickener. This study investigates the efficacy of typical training and use of consistency guides, the Thickness Indicator Model ( TIM) tubes, in helping carers to modify fluids accurately. Method A 3 × 3 pre-post experimental design with a control group was employed to compare the observed accuracy of modification across three groups and at three time points (pre-intervention baseline, immediately post-training intervention and 3-10 months post-training). Sixty-two paid carers who supported people with ID were recruited to participate in the study and each was randomly allocated to one of the three groups: a control group given written guidance only, a group who received typical training and written guidance and a group who received training, written guidance and the TIM tubes. Results & Conclusions Typical training resulted in significantly greater carer accuracy in modifying fluid consistencies when compared with written guidance alone. Use of the TIM tubes also significantly improved accuracy in the modification of drinks compared with the group who modified with the aid of written guidance alone. At 3-10-month follow-up only the group who received typical training alongside the TIM tubes were significantly more accurate than the Written Guidance group. Further research is warranted to ascertain the effectiveness of the training and the utility of the TIM tubes in improving accuracy over a longer time scale and in individuals' usual living environments.

Aim To assess the efficacy of a 0.07% cetylpyridinium chloride ( CPC) mouth rinse in the control of plaque and gingival inflammation during a 6-month period. Material and Methods Adult subjects with moderate gingivitis were selected [≥40% bleeding on marginal probing ( BOMP)]. After retrieving microbiological samples and evaluating the clinical parameters (plaque, BOMP and stain indexes), a professional prophylaxis was performed and subjects were randomly assigned to the test ( CPC mouth rinse) or to the placebo group. Subjects were re-assessed after 3 and 6 months. Results A total of 67 patients (35 test, 32 placebo) were included in the analysis. At 6 months, intra-group significant plaque reductions were observed in the test group (0.691, p < 0.001), but not in the placebo (0.181, p = 0.653). At 6 months, the mean BOMP values were lower in the test group ( p = 0.052). Changes between baseline and 6 months were significantly higher in the test group both for plaque ( p = 0.002) and BOMP ( p = 0.037) when compared with the placebo. A microbiological impact was observed in the test group, especially for Prevotella intermedia. Conclusion The evaluated 0.07% CPC-based mouth rinse, used three times per day adjunctively to mechanical tooth cleaning, prevents plaque accumulation and gingival inflammation, as compared to the placebo, for at least 6 months.
