Abstract
BACKGROUND Oral care regimens can be explored to improve oral health in patients with gingivitis. This study aimed to evaluate the efficacy of a multicomponent oral care regimen with a dual zinc plus arginine (DZA) toothpaste and cetylpyridinium chloride with zinc lactate (CPC + Zn) mouthwash in reducing gingival bleeding in patients with gingivitis. METHODS This randomized clinical trial included 94 participants with gingivitis who were randomized into two groups: the DZA/CPC + Zn group, which used a 1450-ppm fluoride toothpaste containing 0.96% zinc plus 1.5% arginine and a fluoride-containing mouthwash with 0.075% CPC and 0.28% zinc lactate, and the control group, which used a 1450-ppm fluoride toothpaste and a placebo mouthwash for 6 months. All participants were examined by a blinded examiner who measured the gingival index, plaque index, and gingival severity index. Data were analyzed using paired t test, independent t test, and analysis of covariance (ANCOVA). RESULTS Both groups presented statistically significant reductions in all clinical parameters compared to baseline. The DZA/CPC + Zn group exhibited significantly greater reductions in gingival index, gingival severity index, proximal gingival index, plaque index and proximal plaque index compared to the control group at 1, 3, and 6 months. Furthermore, DZA/CPC + Zn significantly decreased the percentage of patients with generalized gingivitis over a 6-month follow-up period. However, differences between the DZA/CPC + Zn and the control groups were not maintained after both groups established similar regimens with fluoride toothpaste. CONCLUSION The multicomponent oral care regimen consisting of DZA toothpaste and CPC + Zn mouthwash is effective in reducing gingival inflammation and supragingival biofilm in patients with gingivitis.

Abstract
BACKGROUND Shoulder pain affects millions of workers worldwide and is considered one of the leading causes of absenteeism and presenteeism. Therefore, using exercises in the work environment emerges as a strategy to prevent or reduce shoulder pain. OBJECTIVE The objective of this study was to evaluate the effects of a workplace-based exercise program on shoulder pain and function in fruit workers. METHODS This was an 8-week parallel two-arm randomized controlled trial. Forty-four fruit workers who reported chronic shoulder pain were randomized to an Experimental Group (EG) or Control Group (CG). The EG was submitted to a program of resistance and stretching exercises for eight weeks, twice a week. The CG received a booklet with muscle stretching and mobility exercises. The primary outcome was shoulder pain intensity; the secondary outcomes were Shoulder Pain and Disability Index (SPADI) and perceived global effect. RESULTS Both groups showed reductions in pain intensity EG: 4.26 (95% CI 2.78-5.74) and CG: 3.74 (95% CI 1.98-5.50) points. The SPADI results showed an average reduction of 17.76 (CI 95% 3.10-32.43) for the EG and 18.39 (CI 95% 3.66-33.13) for the CG. The mean value of the perceived global effect for the CG was 3.45±2.01, and for the EG, the mean was 4.13±1.24. No differences were observed between groups in any outcome analyzed. CONCLUSION Both groups showed significant changes in the analyzed outcomes. However, the workplace-based exercise program was not superior to the exercise booklet.

Abstract
INTRODUCTION Since the 2017 Nobel Prize awarded to J. Hall, M. Rosbash and M.W. Young for their discoveries of molecular mechanisms behind the biological clock, circadian rhythm-based therapy, also known as chronotherapy, is receiving more attention in oncology and the number of anatomical sites of interest in this field is increasing. This observation is in line with the clinical evidence provided by trials on head and neck, lung, colorectal and cervical cancers, as well as the presently ongoing chronotherapy trials for breast and brain cancers. AREAS COVERED The aim of this review was to collate all randomized trials conducted on chronotherapy for various tumor sites and to appraise the evidence for chrono-oncology to advance personalized therapy. Relevant literature was collected from Pubmed/Medline databases and from clinicatrials.gov. EXPERT OPINION Current randomized clinical trials offer a certain level of evidence for the potential of chronotherapy to personalize oncologic treatment. However, comparison of trial results is hindered by the differences in timing of radiation/chemotherapy, the absence of harmonized recommendations for treatment outcome evaluation and not ultimately, the general lack of considering gender as a matched variable in trials, which was found to be a powerful factor influencing response to treatment.

Abstract
Transcranial direct current stimulation (tDCS) has gained popularity as a method of modulating cortical excitability in people with physical and mental disabilities. However, there is a lack of consensus on its effectiveness in older individuals. This study aimed to assess the efficacy of a 2-month tDCS program for improving physical and mental performance in community-dwelling older individuals. In this single-blinded, controlled clinical trial, forty-two participants were allocated to one of three groups: (1) the tDCS group, which received, twice a week, 20 min sessions of 2 mA electric current through electrodes placed on the dorsolateral prefrontal cortex; (2) the tDCS-placebo group, which underwent the same electrode placement as the tDCS group but without actual electric stimulation; and (3) the cognitive-control group, which completed crossword puzzles. Main outcome measures were cognition, mobility, and anxiety. Multivariate analyses of variance were employed. Significance was set at 5% (p < 0.05). Regarding the results, no significant benefits were observed in the tDCS group compared with the tDCS-placebo or cognitive-control groups for cognition (p = 0.557), mobility (p = 0.871), or anxiety (p = 0.356). Cognition exhibited positive oscillations during the assessments (main effect of time: p = 0.001). However, given that all groups showed similar variations in cognitive scores (main effect of group: p = 0.101; group × time effect: p = 0.557), it is more likely that the improvement reflects the learning response of the participants to the cognitive tests rather than the effect of tDCS. In conclusion, a 2-month tDCS program with two sessions per week appears to be ineffective in improving physical and mental performance in community-dwelling older individuals. Further studies are necessary to establish whether or not tDCS is effective in healthy older individuals.

Abstract
AIM To compare, at different levels from the alveolar crest, the radiographic outcomes of equine-derived collagenated xenogeneic bone blocks (CXBB) and autogenous bone blocks (ABB) used for lateral alveolar ridge augmentation. MATERIALS AND METHODS Sixty-four patients with tooth gaps in atrophic alveolar ridges with ≤4 mm were randomly assigned to lateral augmentation using CXBB or ABB. The lateral bone thickness (LBT) was measured 2, 4, 6, 8, and 10 mm below the alveolar crest using CBCT scans obtained before augmentation surgery and at 30 weeks, prior to implant placement. Statistical analysis was performed using Shapiro-Wilk, Fisher's exact, Mann-Whitney, and Wilcoxon signed-rank tests. RESULTS Both CXBB and ABB resulted in significant total and buccal LBT gains at 2, 4, 6, 8, and 10 mm. LBT gains were similar between CXBB- and ABB-augmented sites, except for greater buccal LBT gains at 8 mm at CXBB-augmented sites. While ABB-augmented sites gained vertical bone height, CXBB-treated sites suffered vertical bone loss (CXBB: -0.16 mm; ABB: 0.38 mm, p < .0009). CONCLUSIONS CXBB and ABB were both associated with significant and similar LBT gains at 30 weeks.

Abstract
Crack-cocaine dependence is a severe condition with a high mortality rate. This single case study report details the first deep brain stimulation (DBS) trial targeting the sub-thalamic nucleus (STN) for crack-cocaine dependence. The investigation aimed to assess the effects of STN-DBS on cocaine craving and cocaine use, as well as STN-DBS safety and tolerance in this indication. In this pilot study, we performed double blind cross-over trials, with "ON-DBS" vs. "SHAM-DBS" for 1-month periods. STN-DBS failed to reduce cocaine craving and use. An episode of DBS-induced hypomania occurred after several weeks of cocaine intake at stimulation parameters previously well tolerated. Future research on cocaine dependence should be conducted after a prolonged abstinence period and/or explore novel types of stimulation patterns.

Abstract
Non-alcoholic Fatty Liver Disease (NAFLD) is a global health problem that can progress to steatohepatitis and cirrhosis. The aim of this study was to determine the effect of curcumin + piperine on cardiometabolic risk factors, as well as hepatic steatosis and fibrosis in NAFLD patients with moderate-to-high hepatic steatosis. Patients diagnosed with moderate-to-high NAFLD by liver sonography were randomized to either curcumin + piperine (500 mg/day curcumin plus 5 mg/day piperine) for 12 weeks (n = 30) or placebo groups (n = 30). Liver fibroscan, anthropometric measurements, dietary intake, physical activity, blood pressure, lipid profile, high-sensitivity C-reactive protein, fasting blood glucose (FBG), and liver enzymes were assessed at baseline and after 12 weeks of follow-up. Intention-to-treat analysis was undertaken. Curcumin + piperine decreased waist circumference (p = 0.026), systolic blood pressure (p = 0.001), total cholesterol (p = 0.004), low-density lipoprotein-cholesterol (p = 0.006), FBG (p = 0.002), alanine transaminase (p = 0.007) and aspartate transaminase (p = 0.012) compared with placebo. However, fibroscan measurement did not differ between curcumin + piperine and placebo groups (p > 0.05). Fibroscan measurement as a marker of NAFLD improvement did not differ after 12 weeks of curcumin + piperine; however, curcumin + piperine may be considered as an adjunct therapy to improve anthropometric measures, blood pressure, lipid profile, blood glucose, and liver function in NAFLD patients.

Abstract
Tooth germ autotransplantation of open apices of the teeth exhibits high pulpal healing rates, whereas that of mature permanent teeth normally causes irreversible pulpal necrosis. Extraoral root-end resection (EORER) during transplantation may promote pulpal revascularization (PRV) in transplanted mature teeth and reduce endodontic treatment requirement. This study compared the primary outcomes of survival rates, PRV, and root resorption and determined relevant confounders in autotransplanted mature and immature teeth. The medical charts of consecutive patients who underwent tooth autotransplantation between January 2017 and March 2021 were evaluated. Teeth with a documented follow-up of at least 1 year were included. During the study period, 59 teeth were transplanted in 44 patients. Overall, 2 teeth were excluded owing to missing data; 57 teeth were analyzed, including 25 mature teeth additionally treated with EORER. After a mean follow-up of 21.2 ± 16.1 months, no significant differences in primary outcomes were detected. Fifty-five teeth remained in situ (96.5%), and radiological signs of root resorption were detected in 9/57 teeth (15.8%). PRV was positive in 54/57 teeth (94.7%). Surgical duration and PRV failure were significantly associated with high incidences of root resorption. Mature teeth autotransplantation with EORER yielded similar results to immature teeth autotransplantation and is a feasible treatment option. Long surgery and failed revascularization increased root resorption rates. More factors should be evaluated in larger trials with longer observation periods.

Abstract
Background To evaluate the efficacy of short-term lurasidone in antipsychotic treatment-naïve (TN) adolescents with schizophrenia versus those treated previously (TP) with antipsychotics. Methods Patients aged 13–17 with schizophrenia, and a Positive and Negative Symptom Scale (PANSS) score ≥ 70 and < 120, were randomized to 6 weeks of double-blind treatment with lurasidone (40 or 80 mg/day) or placebo. In a post-hoc, pooled-dose analysis, efficacy was evaluated for TN (criteria: never received antipsychotic treatment) versus TP at the time of the study. Treatment response criteria: ≥20% reduction in PANSS total score. Results Altogether, 57 TN and 269 TP patients enrolled in the 6-week DB study. Mean endpoint change in PANSS total score was significantly greater for lurasidone versus placebo in both the TN group (−25.0 vs. -14.4; p < 0.02; effect size = 0.75), and in the TP group (−17.3 vs. -10.0; p < 0.001; effect size = 0.45); and responder rates were higher for lurasidone versus placebo in both the TN group 84.6% versus 38.9%; number needed to treat [NNT] = 3 and in the TP group (60% vs. 42%; NNT = 6). Rates of treatment-emergent adverse events, and mean changes in body weight and metabolic parameters were similar for the TN and TP groups. Conclusions In a 6-week, placebo-controlled trial, lurasidone demonstrated significant efficacy in adolescents with schizophrenia regardless of previous antipsychotic therapy status; however, the effect size was notably larger in the TN patient group. In both the TN and TP groups, minimal effects were noted on weight, metabolic parameters, or prolactin.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) is one of the most common healthcare-associated (HA) infections. Cancer patients, particularly haemato-oncological patients, have an increased risk for CDI due to more risk factors compared with non-cancer patients. The aim of this study was to investigate differences in outcomes associated with HA CDI in patients with solid and haematological malignancies compared with patients with no underlying malignant disease in a tertiary healthcare centre in Serbia. METHODS A prospective cohort study was conducted including adult patients diagnosed with an initial episode of HA CDI. Their demographic and clinical characteristics associated with risk factors for CDI were documented. Outcomes such as all-cause 30-day mortality, cure of infection, diarrhoea relaps and recurrence of disease were followed. Patients were assigned to cancer and non-cancer groups. Within the cancer group, patients were divided into the solid tumour subgroup and haematological malignancy subgroup. RESULTS During a 7-year period, HA CDI was observed in 28 (5.1%) patients with haematological malignancy, 101 (18.3%) patients with solid tumours and 424 (76.7%) non-cancer patients. Older age (OR 1.04, 95% CI 1.02 to 1.07, p<0.001), admission to the intensive care unit (ICU) (OR 2.61, 95% CI 1.37 to 4.95, p=0.003), mechanical ventilation (OR 5.19, 95% CI 2.78 to 9.71, p<0.001) and use of antibiotics prior to CDI (OR 1.04, 95% CI 1.02 to 1.06, p=0.02) were associated with increased mortality. Compared with patients with solid tumours, patients with haematological malignancy were younger (65 vs 57 years, p=0.015), did not require ICU admission (25.0% vs 0%) or mechanical ventilation (8.9% vs 0%) and were treated longer with antibiotics prior to CDI (14 vs 24 days, p=0.002). CONCLUSIONS Patients with haematological malignancy were exposed to different risk factors for CDI associated with mortality compared with patients with solid tumours and non-cancer patients. Older age, ICU stay and mechanical ventilation, but not presence or type of cancer, predicted the all-cause 30-day mortality.

Abstract
Background Calcific uraemic arteriolopathy (CUA; calciphylaxis) is a rare disease seen predominantly in patients receiving dialysis. Calciphylaxis is characterized by poorly healing or non-healing wounds, and is associated with mortality, substantial morbidity related to infection and typically severe pain. In an open-label Phase 2 clinical trial, SNF472, a selective inhibitor of vascular calcification, was well-tolerated and associated with improvement in wound healing, reduction of wound-related pain and improvement in wound-related quality of life (QoL). Those results informed the design of the CALCIPHYX trial, an ongoing, randomized, placebo-controlled, Phase 3 trial of SNF472 for treatment of calciphylaxis. Methods In CALCIPHYX, 66 patients receiving haemodialysis who have an ulcerated calciphylaxis lesion will be randomized 1:1 to double-blind SNF472 (7 mg/kg intravenously) or placebo three times weekly for 12 weeks (Part 1), then receive open-label SNF472 for 12 weeks (Part 2). All patients will receive stable background care, which may include pain medications and sodium thiosulphate, in accordance with the clinical practices of each site. A statistically significant difference between the SNF472 and placebo groups for improvement of either primary endpoint at Week 12 will demonstrate efficacy of SNF472: change in Bates-Jensen Wound Assessment Tool-CUA (a quantitative wound assessment tool for evaluating calciphylaxis lesions) or change in pain visual analogue scale score. Additional endpoints will address wound-related QoL, qualitative changes in wounds, wound size, analgesic use and safety. Conclusions This randomized, placebo-controlled Phase 3 clinical trial will examine the efficacy and safety of SNF472 in patients who have ulcerated calciphylaxis lesions. Patient recruitment is ongoing.

Abstract
WHAT IS KNOWN AND OBJECTIVE The discussion about health equity in the United States frequently involves concerns over racial and ethnic minority under-representation in clinical trials and particularly in trials conducted in support of product approvals. The FDA has long worked to encourage diverse participation in clinical trials and through its Drug Trials Snapshots (DTS) program, the U.S. Food and Drug Administration (FDA) has moved to make trial demographic data more accessible and transparent. We conducted a demographic study of U.S. participants in clinical trials for FDA-approved new drugs (new molecular entities [NMEs], and original Biologics License Applications [BLAs]) from 2015 to 2019, as reported in DTS database with a purpose of understanding the extent to which U.S.-based trials used to support product approvals represent the racial and ethnic diversity of the U.S. population by therapeutic area. METHODS Participant-level trial data were collected by accessing the FDA electronic common technical document (eCTD), for the applications used to publish each Snapshot. The therapeutic area (TA) for each drug was determined by review division assignment. The demographic data were analysed and compared to U.S. census data. RESULTS AND DISCUSSION We examined 102,596 U.S. participants in trials of new drugs that were approved and presented in Drug Trials Snapshots between 2015 and 2019. White participation ranged from 51% in psychiatric trials to 90% in cardiovascular (CV) trials; Black or African American participation ranged from 5% in medical imaging to 45% in psychiatric trials; Asian participation ranged from 0.75% in CV to 4% in dermatologic trials; and Hispanic or Latino participation ranged from 1% in medical imaging to 22% in infectious diseases and gastroenterology trials. WHAT IS NEW AND CONCLUSION Our data showed variable representation of racial and ethnic minorities across therapeutic areas at the U.S. sites. Blacks or African Americans were represented at or above U.S. census estimates across most therapeutic areas, while Asians and American Indian or Alaska Natives were consistently underrepresented. Hispanic or Latino participation across most therapeutic areas was below U.S. census estimates, however, more variable, and a sizable proportion of data was missing. The next step is a comparison of trial participation based on disease prevalence and epidemiology, which is a more accurate assessment of trial diversity.

Abstract
BACKGROUND/AIMS Ensuring verum and placebo cannot be visually distinguished from each other is a critical aspect of blinded controlled clinical trials. Our objective was to propose a rational approach to the visual evaluation of placebo matching candidates. METHODS Verum and placebo samples were prepared in clear clinical ancillary supplies (intravenous bags, syringes and administration lines) covered at different levels using opaque sleeves. Triangle and tetrad tests, two sensory discriminative testing methods widely used in the food industry, were applied to assess visual differences between verum and placebo. RESULTS Triangle and tetrad test results allowed defining the level of opaque coverage required to ensure blinding for three biological drug molecules of therapeutic interest. While the limited number of panelists did not allow a statistically sound comparison of triangle and tetrad test methodologies, tetrad test has a theoretical higher power than triangle test, meaning fewer panelists are needed to reach the same statistical conclusion. CONCLUSION Tetrad test offers a rational approach to define a blinding strategy for ancillary supplies used in a controlled clinical trial.

Abstract
What is known and objective Since WHO declared the pandemic of COVID‐19, vaccines have been developed to fight against this infectious disease. Coordination and participation of investigational drug services to facilitate a phase III COVID‐19 vaccination clinical trial are described and discussed, with novel interventions coordinating the dispensing processes in the trailer settings. Comment Once the study has reached phase III, the large number of participants and fast enrolment would contribute to the vaccine development. What is new and Conclusion The investigational drug service (IDS) performed responsibilities in clinical and trailer units, and minimized workflow disturbances to maximize validity during the dispensing process. The advantages of mobile units and trailers increase flexibility of participants, broaden service area and improve feasibility, especially in minority and underserved communities. The UCM IDS team performs responsibilities in both clinical and mobile unit settings, the IDS team is able to facilitate and expand the enrolment to the minority population in underserved communities.

Abstract
OBJECTIVE This study aims to assess the effectiveness of a 12-weeks self-management and exercise intervention to improve self-efficacy in older individuals with knee osteoarthritis (KOA) DESIGN: Randomised Controlled Trial. SETTING Four different community settings. SUBJECTS Eighty individuals aged 60 years or over with clinical and radiographic knee osteoarthritis. INTERVENTION The subjects were randomly assigned to (1) a combined self-management and exercise programme (treatment group) and (2) an educational programme (control group). MAIN MEASURES The primary outcome was self-efficacy and secondary outcomes were physical activity, health-related quality of life and skill-related physical fitness measures. RESULTS Sixty-seven participants, mean age 69.1 (5.8) years, completed the study: 32 in the control group and 35 in the treatment group. A significant group effect favourable to the treatment group was observed in the following variables: self-efficacy (F[2,64] = 9.2, p = 0.003), physical activity (F[2,64] = 43.6, p < 0.001) and balance for most painful knee (F(2,64) = 4.87, p = 0.031) and less painful knee (F[2,64] = 6.94, p = 0.010). No improvements regarding health-related quality of life, gait speed and agility were found. This study supports the importance of a combined self-management and exercise intervention to improve self-efficacy and physical activity in KOA individuals.

Abstract
Background Barth syndrome is a rare, life-threatening, X-linked recessive genetic disease that predominantly affects young males and is caused by abnormal mitochondrial lipid metabolism. Currently, there is no definitive treatment for Barth syndrome other than interventions to ameliorate acute symptoms, such as heart failure, cardiac arrhythmias, neutropenia, and severe muscle fatigue. Previous mechanistic studies have identified the lipid-lowering drug bezafibrate as a promising potential treatment; however, to date, no human trials have been performed in this population. Objective The aim of this study is to determine whether bezafibrate (and resveratrol in vitro) will increase mitochondrial biogenesis and potentially modify the cellular ratio of monolysocardiolipin (MLCL) to tetralinoleoyl-cardiolipin (L4-CL), ameliorating the disease phenotype in those living with the disease. Methods The CARDIOMAN (Cardiolipin Manipulation) study is a UK single-center, double-blinded, randomized, placebo-controlled crossover study investigating the efficacy of bezafibrate in participants with Barth syndrome. Treatment was administered in two 15-week phases with a minimum washout period of 1 month between the phases where no treatment was administered. The primary outcome is peak oxygen consumption (VO2 peak). Secondary outcomes include MLCL/L4-CL ratio and CL profile in blood cells, amino acid expression, phosphocreatine to adenosine triphosphate ratio in cardiac muscle and skeletal muscle oxidative function on phosphorus-31 magnetic resonance spectroscopy, quality of life using the Pediatric Quality of Life Inventory questionnaire, absolute neutrophil count, cardiac function and rhythm profiles at rest and during exercise, and mitochondrial organization and function assessments. Outcomes were assessed at baseline and during the final week of each treatment phase. Results A total of 12 patients were scheduled to participate across three consecutive research clinics between March and April 2019. In total, 11 participants were recruited, and the follow-up was completed in January 2020. Data analysis is ongoing, with publication expected in 2021. Conclusions This trial was approved by the United Kingdom National Research Ethics Service Committee and the Medicines and Healthcare products Regulatory Agency. The feasibility of the CARDIOMAN study will help to inform the future conduct of randomized controlled trials in rare disease populations as well as testing the efficacy of bezafibrate as a potential treatment for the disease and advancing the mechanistic understanding of Barth syndrome.

Abstract
BACKGROUND AND OBJECTIVES The Acute Kidney Outreach to Reduce Deterioration and Death trial was a large pilot study for a cluster-randomized trial of acute kidney injury (AKI) outreach. METHODS An observational control (before) phase was conducted in two teaching hospitals (9 miles apart) and their respective catchment areas. In the intervention (after) phase, a working-hours AKI outreach service operated for the intervention hospital/area for 20 weeks, with the other site acting as a control. All AKI alerts in both hospital and community patients were screened for inclusion. Major exclusion criteria were patients who were at the end of life, unlikely to benefit from outreach, lacking mental capacity or already referred to the renal team. The intervention arm included a model of escalation of renal care to AKI patients, depending on AKI stage. The 30-day primary outcome was a combination of death, or deterioration, as shown by any need for dialysis or progression in AKI stage. A total of 1762 adult patients were recruited; 744 at the intervention site during the after phase. RESULTS A median of 3.0 non-medication recommendations and 0.5 medication-related recommendations per patient were made by the outreach team a median of 15.7 h after the AKI alert. Relatively low rates of the primary outcomes of death within 30 days (11-15%) or requirement for dialysis (0.4-3.7%) were seen across all four groups. In an exploratory analysis, at the intervention hospital during the after phase, there was an odds ratio for the combined primary outcome of 0.73 (95% confidence interval 0.42-1.26; P = 0.26). CONCLUSIONS An AKI outreach service can provide standardized specialist care to those with AKI across a healthcare economy. Trials assessing AKI outreach may benefit from focusing on those patients with 'mid-range' prognosis, where nephrological intervention could have the most impact.

Abstract
BACKGROUND Ebola virus RNA persists in the semen of male Ebola survivors for months to years after the acute infection and male-to-female sexual transmission of the virus is well documented. We investigated whether remdesivir can safely reduce persistence of seminal Ebola virus RNA. METHODS We recruited men with persistent seminal Ebola RNA in Liberia and in Guinea. Participants were randomized 1:1 to receive intravenous remdesivir (GS-5734; Gilead Sciences) or matching placebo administered once daily by intravenous infusion over one hour on 5 consecutive days. Stratification was by country and number of positive (1 or 2) pre-enrollment semen tests. The study team was blinded to treatment group allocation and specific liver related lab results. We evaluated the difference in mean assay negativity rate (ANR), i.e., the proportion of negative tests for each participant in each group in the treatment (days 1-28) and follow-up (months 2-6) phases, on an intention-to-treat basis. ClinicalTrials.gov NCT02818582; closed. RESULTS We enrolled 38 men from July 2016 through June 2018. The mean treatment phase ANRs were 85% (sd=24%) and 76% (sd=30%) in the remdesivir and placebo arms, respectively (p=0.270). The mean follow-up phase ANRs were 96% (sd=10%) and 81% (sd=29%) in the remdesivir and placebo arms, respectively (p=0.041). The five-day remdesivir regimen was well-tolerated with no safety concerns. CONCLUSIONS In this small trial, remdesivir 100mg/day for five days safely reduced the presence of Ebola virus RNA in the semen of Ebola survivors two to six months after administration. A larger follow up study is necessary to confirm results.

Abstract
Brief motivational intervention (bMI) is a therapeutic approach that encourages self-efficacy and may have a positive effect on breastfeeding self-efficacy (BSE). The purpose of this study was to analyze the effectiveness of a bMI in increasing BSE in women who started breastfeeding in the immediate postpartum period and to explore the roles of general self-efficacy and other baseline variables in this relationship. A randomized, parallel-group clinical trial was carried out. A bMI was compared with an educational session on breastfeeding. Changes in BSE and its dimensions and the interaction and mediation/moderation of general self-efficacy and other variables were analyzed. BSE increased in the bMI group from a mean baseline score of 59.14 (±9.35) to 64.62 (±7.91) at 1st month (p < 0.001). An interaction was found in that only women with higher education had an improvement in BSE during the follow-up period that was attributable to the bMI (mean difference between the bMI and the attention control group: 18.25 (95% confidence interval: 5.86-30.19; p = 0.006). This interaction was not found for the changes produced in the intrapersonal thoughts dimension of BSE, whose scores were higher in the bMI group at 3 and 6 months. General self-efficacy exerted a moderating effect on the association of bMI with BSE change. The effect of bMI was no longer significant when the general self-efficacy score was above 84. Thus, bMI is effective in increasing BSE. This effectiveness was limited by the mother's educational level and moderated by baseline general self-efficacy.

Abstract
Background In the predictD-intervention, GPs used a personalised biopsychosocial programme to prevent depression. This reduced the incidence of major depression by 21.0%, although the results were not statistically significant. Aim To determine whether the predictD-intervention is effective at preventing anxiety in primary care patients without depression or anxiety. Design and setting Secondary study of a cluster randomised trial with practices randomly assigned to either the predictD-intervention or usual care. This study was conducted in seven Spanish cities from October 2010 to July 2012. Method In each city, 10 practices and two GPs per practice, as well as four to six patients every recruiting day, were randomly selected until there were 26–27 eligible patients for each GP. The endpoint was cumulative incidence of anxiety as measured by the PRIME-MD screening tool over 18 months. Results A total of 3326 patients without depression and 140 GPs from 70 practices consented and were eligible to participate; 328 of these patients were removed because they had an anxiety syndrome at baseline. Of the 2998 valid patients, 2597 (86.6%) were evaluated at the end of the study. At 18 months, 10.4% (95% CI = 8.7% to 12.1%) of the patients in the predictD-intervention group developed anxiety compared with 13.1% (95% CI = 11.4% to 14.8%) in the usual-care group (absolute difference = −2.7% [95% CI = −5.1% to −0.3%]; P = 0.029). Conclusion A personalised intervention delivered by GPs for the prevention of depression provided a modest but statistically significant reduction in the incidence of anxiety.

Abstract
BACKGROUND It seems alternative treatments such as antioxidant intervention and anti-inflammatory intervention adjuvant to antibiotic regimens may enhance cancer prevention approaches and decrease adverse side effects related to therapeutic antibiotic regimens. So, we will evaluate the effects of concurrent omega-3 and cranberry juice supplementation along with standard antibiotic therapy on the eradication of Helicobacter pylori, gastrointestinal symptoms, some serum inflammatory and oxidative stress markers in adults with HP infection. METHODS We will conduct a 4-week double-blinded randomized clinical trial. The subjects will be randomly stratified according to sex and BMI using a permuted block randomization procedure by Random Allocation Software (RAS). They will be assigned to one of the four study groups: (1) cranberry juice fortified with omega-3 Intervention (n=23), (2) cranberry juice intervention group (n=23), (3) placebo beverage fortified with omega-3 intervention group (n=23), and (4) placebo beverage intervention (control group) (n=23). All statistical analyses will be performed using IBM SPSS Statistics software. DISCUSSION A combination of alternative therapies may have a synergistic effect compared to a single approach. It could potentially be more effective in promoting the efficacy of standard antibiotic therapy in eradicating HP infection. TRIAL REGISTRATION Iranian Registry of Clinical Trials (IRCT20151128025274N3, www.irct.ir/trial/28997). TRIAL STATUS This study is in the early stages of sampling.

Abstract
OBJECTIVES To analyze the effect of graduated compression stockings on the venous reflux in the lower limbs of pregnant women. METHOD A controlled randomized clinical trial was performed with sixty women: intervention group (n = 30), who used compression stockings, and control group (n = 30). Using duplex-ultrasound, the reflux time and peak reflux velocity in the great saphenous vein and small saphenous vein were analyzed. RESULTS Great saphenous vein reflux times in the intervention group were 0.13 s at the beginning (initial) and 0.04 s at the end of pregnancy (final) in the right leg and 0.02 s and 0.34 s (p < 0.0001) in the control group. No patient in the intervention group experienced pathological reflux at the end of the pregnancy. There was a significant difference in the reflux time measured from both the great saphenous vein and small saphenous vein and peak reflux velocity between the groups. CONCLUSION Compression stockings prevent increased venous reflux in lower limbs of pregnant women.

Abstract
Dietary intervention is an enticing approach in the fight against cognitive impairment. Nutritional supplements and dietetic counseling are relatively easy and benign interventions, but research has not yet yielded irrefutable evidence as to their clinical utility. Heterogeneity in the results of available clinical studies, as well as methodological and practical issues, does not allow replication and generalization of findings. The paper at hand reviews only randomized clinical trials of single nutrients, multi-nutrient formulations and dietary counseling in mild cognitive impairment and dementia of the Alzheimer's type focusing on both cognitive and functional outcomes. Thus far, folate, vitamin E, Ω-3 fatty acids, and certain multi-nutrient formulations have shown some preliminary promising results; larger, well-designed trials are needed to confirm these findings before nutritional elements can be incorporated in recommended clinical guidelines.

Abstract
Recent reports indicated that curcumin had beneficial effects in animal models of liver injury and cirrhosis. Current study aimed to investigate the effects of curcumin supplementation in patients with liver cirrhosis. In this randomized double-blind placebo-controlled trial, 70 patients with liver cirrhosis aged 20-70 years were randomly divided into two groups to receive 1,000 mg/day curcumin (n = 35) or placebo (n = 35) for 3 months. Model for end-stage liver disease (MELD) (i), MELD, MELD-Na, and Child-Pugh scores were used to assess the severity of cirrhosis. Sixty patients (29 in the curcumin group and 31 in the placebo group) completed the study. MELD(i) (15.55 ± 3.78 to 12.41 ± 3.07), MELD (15.31 ± 3.07 to 12.03 ± 2.79), MELD-Na (15.97 ± 4.02 to 13.55 ± 3.51), and Child-Pugh (7.17 ± 1.54 to 6.72 ± 1.31) scores decreased significantly in the curcumin group after 3-month intervention (p < .001, p < .001, p = .001, and p = .051, respectively), whereas they increased significantly in the placebo group (p < .001, p < .001, p < .001, p = .001, respectively). Significant differences were only observed between the two groups in MELD(i), MELD, MELD-Na, and Child-Pugh scores after 3-month intervention (p < .001 for all of them). In this pilot study, beneficial effects of curcumin supplementation were observed in decreasing disease activity scores and severity of cirrhosis in patients with cirrhosis.

Abstract
OBJECTIVE To examine the effect of a case manager-assisted rehabilitation programme as an add-on to usual physical rehabilitation in patients undergoing lumbar spinal fusion. DESIGN A randomized controlled trial with a two-year follow-up. SETTINGS Outpatient clinics of a university hospital and a general hospital. SUBJECTS In total, 82 patients undergoing lumbar spinal fusion. INTERVENTIONS The patients were randomized one-to-one to case manager-assisted rehabilitation (case manager group) or no case manager-assisted rehabilitation (control group). Both groups received usual physical rehabilitation. The case manager-assisted rehabilitation programme included a preoperative meeting with a case manager to determine a rehabilitation plan, postsurgical meetings, phone meetings, and voluntary workplace visits or roundtable meetings. MAIN MEASURES Primary outcome was the Oswestry Disability Index. Secondary outcomes were back pain, leg pain, and return to work. RESULTS Of the 41 patients in the case manager group, 49% were men, with the mean age of 46.1 (±8.7 years). In the control group, 51% were male, with the mean age of 47.4 (±8.9 years). No statistically significant between-group differences were found regarding any outcomes. An overall group effect of 4.1 points (95% confidence interval (CI): -1.8; 9.9) was found on the Oswestry Disability Index, favouring the control group. After two years, the relative risk of return to work was 1.18 (95% CI: 0.8; 1.7), favouring the case manager group. CONCLUSION The case manager-assisted rehabilitation programme had no effect on the patients' functional disability or back and leg pain compared to usual physical rehabilitation. The study lacked power to evaluate the impact on return to work.

Abstract
Background and Objectives: Maxillary bone defects related to post-extraction alveolar ridge resorption are usual. These defects may lead to failure in further surgical implant phases given the lack of bone volume to perform the dental implant. The objective of this clinical assay was to evaluate the safety and efficacy of an experimental synthetic bone substitute in the preservation of post-extraction maxillary alveoli. Materials and Methods: 33 voluntary patients who had at least one maxillary premolar tooth that was a candidate for exodontia (n = 39) and subsequent implant rehabilitation participated. The regenerated alveoli were monitored by means of periodic clinical examinations (days 9 ± 1, 21 ± 4, 42 ± 6, and 84 ± 6), measuring the height and width of the alveolar crest (days 0 and 180 ± 5), measurement of radiodensity using tomographic techniques (days 0–5 and 175 ± 5), and histological examination of biopsies collected at 180 ± 5 days. Results: No significant differences were observed during the entire follow-up period between the two groups with respect to the safety variables studied. A variation in width of −0.9 ± 1.3 mm and −0.6 ± 1.5 mm, and a variation in height of −0.1 ± 0.9 mm and −0.3 ± 0.7 mm was observed for experimental material Sil-Oss® and Bio-Oss®, respectively. The radiodensity of the alveoli regenerated with the experimental material was significantly lower than that corresponding to Bio-Oss®. However, the histological study showed greater osteoid matrix and replacement of the material with newformed bone in the implanted beds with the experimental material. Conclusions: Both materials can be used safely and proved equally effective in maintaining alveolar flange dimensions, they are also histologically biocompatible, bioactive and osteoconductive. The experimental material showed the advantage of being resorbable and replaced with newformed bone, in addition to promoting bone regeneration.

Abstract
AIM To evaluate the effectiveness on lifestyle change of an mHealth intervention to promote healthy behaviours in adolescence (TeenPower) and to analyse the predictors of the mHealth intervention effectiveness. DESIGN This study is designed as a non-randomized controlled trial with a two-arm structure. METHODS Adolescents of 12-16-year old were recruited from three school districts, with access to the Internet and smartphone/tablet devices. The intervention group was invited to engage in the mHealth intervention (TeenPower) for 6 months in addition to a school-based intervention. The control group only followed the school-based intervention. A repeated measures factorial ANOVA was used and the main effectiveness outcome was the lifestyle change measured by the adolescent lifestyle profile. RESULTS The outcomes of the mHealth intervention (TeenPower) show a significant effect on nutrition (ƞ2 p = 0.03, p = .03), positive life perspective (ƞ2 p = 0.04, p = .01), and global lifestyle (ƞ2 p = 0.02, p = .05), with a dropout rate of 62.1%. The analysis of the effectiveness predictors of the mHealth intervention suggested that older adolescents tended to show a significant increase in the rates of stress management (r = .40; p < .05). CONCLUSIONS Although the considerable dropout rate, the mHealth intervention presented significant impact on multiple lifestyle domains, providing support for the effectiveness of mHealth interventions for health promotion as an add-on to standard interdisciplinary interventions. IMPACT Adolescents must have the necessary and appropriate knowledge for the correct and responsible decision-making regarding their health and lifestyle. Innovative strategies (mHealth intervention) were used to promote healthy behaviours. This study evaluates the effectiveness of an mHealth intervention (TeenPower) specifically designed for adolescents. We found a significant impact in several lifestyle domains such as health responsibility, nutrition, positive life perspective, and global lifestyle.

Abstract
Lower respiratory tract infections (LRTIs) refer to the inflammation of the trachea, bronchi, bronchioles, and lung tissue. Old people have an increased risk of developing LRTIs compared to young adults. The prevalence of LRTIs in the elderly population is not only related to underlying diseases and aging itself, but also to a variety of clinical issues, such as history of hospitalization, previous antibacterial therapy, mechanical ventilation, antibiotic resistance. These factors mentioned above have led to an increase in the prevalence and mortality of LRTIs in the elderly, and new medical strategies targeting LRTIs in this population are urgently needed. After a systematic review of the current randomized controlled trials and related studies, we recommend novel pharmacotherapies that demonstrate advantages for the management of LRTIs in people over the age of 65. We also briefly reviewed current medications for respiratory communicable diseases in the elderly. Various sources of information were used to ensure all relevant studies were included. We searched Pubmed, MEDLINE (OvidSP), EMBASE (OvidSP), and ClinicalTrials.gov. Strengths and limitations of these drugs were evaluated based on whether they have novelty of mechanism, favorable pharmacokinetic/pharmacodynamic profiles, avoidance of interactions and intolerance, simplicity of dosing, and their ability to cope with challenges which was mainly evaluated by the primary and secondary endpoints. The purpose of this review is to recommend the most promising antibiotics for treatment of LRTIs in the elderly (both in hospital and in the outpatient setting) based on the existing results of clinical studies with the novel antibiotics, and to briefly review current medications for respiratory communicable diseases in the elderly, aiming to a better management of LRTIs in clinical practice.

Abstract
Objectives To evaluate the effectiveness of compression stockings in controlling the varicose veins in pregnant women. Method A prospective controlled randomized clinical trial was performed, including 60 women: intervention group (n = 30), who used compression stockings, and control group (n = 30). Diameters of the great saphenous vein and small saphenous vein in the lower limbs of pregnant women in an orthostatic position were analyzed using Duplex-ultrasound. The symptomatology and CEAP were evaluated. Results Great saphenous vein diameters in the intervention group were 0.37 cm initial and 0.32 cm final (p < 0.0001) in the right leg and 0.28 cm and 0.38 cm (p < 0.0001) in the control group. CEAP classification presented worsening in the control group (p < 0.0001). The signs and symptoms in the control vs. intervention group: pain (86.67% vs. 23.33%; p < 0.0001), edema (70.00% vs. 33.33%; p = 0.0045), and leg heaviness (93.33% vs. 13.33%; p < 0.0001). Conclusions Compression stockings were effective in controlling the varicose veins related to pregnancy.

Abstract
Background Risk-appropriate prenatal care has been asserted as a way for the cost-effective delivery of prenatal care. A virtual care model for prenatal care has the potential to provide patient-tailored, risk-appropriate prenatal educational content and may facilitate vital sign and weight monitoring between visits. Previous studies have demonstrated a safe reduction in the frequency of in-person prenatal care visits among low-risk patients but have noted a reduction in patient satisfaction. Objective The primary objective of this study was to test the effectiveness of a mobile prenatal care app to facilitate a reduced in-person visit schedule for low-risk pregnancies while maintaining patient and provider satisfaction. Methods This controlled trial compared a control group receiving usual care with an experimental group receiving usual prenatal care and using a mobile prenatal care app. The experimental group had a planned reduction in the frequency of in-person office visits, whereas the control group had the usual number of visits. The trial was conducted at 2 diverse outpatient obstetric (OB) practices that are part of a single academic center in Washington, DC, United States. Women were eligible for enrollment if they presented to care in the first trimester, were aged between 18 and 40 years, had a confirmed desired pregnancy, were not considered high-risk, and had an iOS or Android smartphone that they used regularly. We measured the effectiveness of a virtual care platform for prenatal care via the following measured outcomes: the number of in-person OB visits during pregnancy and patient satisfaction with prenatal care. Results A total of 88 patients were enrolled in the study, 47 in the experimental group and 41 in the control group. For patients in the experimental group, the average number of in-person OB visits during pregnancy was 7.8 and the average number in the control group was 10.2 (P=.01). There was no statistical difference in patient satisfaction (P>.05) or provider satisfaction (P>.05) in either group. Conclusions The use of a mobile prenatal care app was associated with reduced in-person visits, and there was no reduction in patient or provider satisfaction.

Abstract
A major problem in mental health clinical trials, such as depression, is low assay sensitivity in primary outcome measures. This has contributed to clinical trial failures, resulting in the exodus of the pharmaceutical industry from the Central Nervous System space. This reduced assay sensitivity in psychiatry outcome measures stems from inappropriately broad measures, recall bias, and poor interrater reliability. Limitations in the ability of traditional measures to differentiate between the trait versus state-like nature of individual depressive symptoms also contributes to measurement error in clinical trials. In this viewpoint, we argue that ecological momentary assessment (EMA)-frequent, real time, in-the-moment assessments of outcomes, delivered via smartphone-can both overcome these psychometric challenges and reduce clinical trial failures by increasing assay sensitivity and minimizing recall and rater bias. Used in this manner, EMA has the potential to further our understanding of treatment response by allowing for the assessment of dynamic interactions between treatment and distinct symptom response.

Abstract
INTRODUCTION Rasagiline is a monoamine oxidase B (MAO-B) inhibitor with possible neuroprotective effects in patients with amyotrophic lateral sclerosis (ALS). METHODS We performed a randomized, double-blind, placebo-controlled trial of 80 ALS participants with enrichment of the placebo group with historical controls (n = 177) at 10 centers in the United States. Participants were randomized in a 3:1 ratio to 2 mg/day rasagiline or placebo. The primary outcome was average slope of decline on the ALS Functional Rating Scale-Revised (ALSFRS-R). Secondary measures included slow vital capacity, survival, mitochondrial and molecular biomarkers, and adverse-event reporting. RESULTS There was no difference in the average 12-month ALSFRS-R slope between rasagiline and the mixed placebo and historical control cohorts. Rasagiline did not show signs of drug-target engagement in urine and blood biomarkers. Rasagiline was well tolerated with no serious adverse events. DISCUSSION Rasagiline did not alter disease progression compared with controls over 12 months of treatment. Muscle Nerve 59:201-207, 2019.

Abstract
BACKGROUND Currently, treatment of latent tuberculosis infection (LTBI) in Australia consists most commonly of a 9-month course of isoniazid (9H). A 3-month course of weekly isoniazid and rifapentine (3HP) has been shown to be as effective as 9 months of daily isoniazid, and associated with less hepatotoxicity; however, rifapentine is not currently available in Australia. Introduction of this regimen would have apparent advantages for people with LTBI in Victoria by safely shortening duration of LTBI therapy. However, the cost benefit of this new therapeutic approach is uncertain. AIM Cost-analysis of standard and short-course therapy for LTBI in an Australian context. METHODS Single-centre randomised controlled trial conducted between December 2013-March 2016. Participants underwent 1:1 randomisation to either a 9-month course of daily isoniazid or a 12-week course of weekly isoniazid and rifapentine. The primary outcome measure was total healthcare system costs (in Australian dollars; AUD) per completed course of LTBI therapy. Secondary cost analyses were performed to consider varying assumptions regarding commercial cost of rifapentine. RESULTS Overall, 34 of 40 (85%) participants in the 9H group and 36/40 (90%) in the 3HR group completed therapy. One patient in the 3HP group was hospitalised for a febrile illness; no hospitalisations were recorded in the 9H group. The cost per completed course of 9H was 601 AUD, while that of 3HP was significantly lower at 511 AUD (P < 0.01). CONCLUSIONS This study provides cost analysis evidence to support the use of 3HP for the treatment of LTBI in Australia.

Abstract
BACKGROUND People with advanced cancer face difficulties with their everyday activities at home that may reduce their health-related quality of life. To address these difficulties, we developed the 'Cancer Home-Life Intervention'. AIM To evaluate the efficacy of the 'Cancer Home Life-Intervention' compared with usual care with regard to patients' performance of, and participation in, everyday activities, and their health-related quality of life. DESIGN AND INTERVENTION A randomised controlled trial ( ClinicalTrials.gov NCT02356627). The 'Cancer Home-Life Intervention' is a brief, tailored, occupational therapy-based and adaptive programme for people with advanced cancer targeting the performance of their prioritised everyday activities. SETTING/PARTICIPANTS Home-living adults diagnosed with advanced cancer experiencing functional limitations were recruited from two Danish hospitals. They were assessed at baseline, and at 6 and 12 weeks of follow-up. The primary outcome was activities of daily living motor ability. Secondary outcomes were activities of daily living process ability, difficulty performing prioritised everyday activities, participation restrictions and health-related quality of life. RESULTS A total of 242 participants were randomised either to the intervention group ( n = 121) or the control group ( n = 121). No effect was found on the primary outcome (between-group mean change: -0.04 logits (95% confidence interval: -0.23 to 0.15); p = 0.69). Nor was any effect on the secondary outcomes observed. CONCLUSION In most cases, the 'Cancer Home-Life Intervention' was delivered through only one home visit and one follow-up telephone contact, which not was effective in maintaining or improving participants' everyday activities and health-related quality of life. Future research should pay even more attention to intervention development and feasibility testing.

Abstract
Bryostatin 1, a potent activator of protein kinase C epsilon (PKCɛ), has been shown to reverse synaptic loss and facilitate synaptic maturation in animal models of Alzheimer’s disease (AD), Fragile X, stroke, and other neurological disorders. In a single-dose (25 μg/m2) randomized double-blind Phase IIa clinical trial, bryostatin levels reached a maximum at 1-2 h after the start of infusion. In close parallel with peak blood levels of bryostatin, an increase of PBMC PKCɛ was measured (p = 0.0185) within 1 h from the onset of infusion. Of 9 patients with a clinical diagnosis of AD, of which 6 received drug and 3 received vehicle within a double-blind protocol, bryostatin increased the Mini-Mental State Examination (MMSE) score by +1.83±0.70 unit at 3 h versus –1.00±1.53 unit for placebo. Bryostatin was well tolerated in these AD patients and no drug-related adverse events were reported. The 25 μg/m2 administered dose was based on prior clinical experience with three Expanded Access advanced AD patients treated with bryostatin, in which return of major functions such as swallowing, vocalization, and word recognition were noted. In one Expanded Access patient trial, elevated PKCɛ levels closely tracked cognitive benefits in the first 24 weeks as measured by MMSE and ADCS-ADL psychometrics. Pre-clinical mouse studies showed effective activation of PKCɛ and increased levels of BDNF and PSD-95. Together, these Phase IIa, Expanded Access, and pre-clinical results provide initial encouragement for bryostatin 1 as a potential treatment for AD.

Abstract
OBJECTIVES This work sought to compare the evaluation of the nursing care provided during the parturition process in the intervention group based on Swanson's theory of caring versus that of the control group that received conventional care. METHODS Preventive-type controlled clinical trial conducted in a tier II hospital in San Gil, Santander (Colombia). During the parturition process, the intervention group received care based on Swanson's theory of caring (n=20) and the control group received conventional care (n=23). During immediate postpartum, the mothers were applied the Professional care rating scale by Swanson, validated into Spanish in Colombia. RESULTS Assessment of professional care in the intervention group was Excellent with an average for the scale total of 59.8 points of a possible maximum of 60 points, while in the control group it was Good with 50.2 (p<0.0001). In the 15 items that make up the scale and in both subscales (Compassionate Healer and Competent Healer) higher scores were also observed in the intervention group compared to those of the control group. Conclusion. The intervention derived from Swanson's theory of caring was associated to a better evaluation of professional nursing care by women during the parturition process.

Abstract
Objectives To establish whether sham acupuncture (SA) or placebo acupuncture (PA) is more efficacious for reducing low back pain (LBP) than other routine treatments and to discuss whether SA or PA is appropriate for randomized controlled trials of acupuncture for LBP. Methods Six databases were searched on 31 May 2017. We included only randomized controlled trials of adults with LBP and lower back myofascial pain syndrome. The studies had at least two control arms: a sham-controlled acupuncture arm and a routine care or waiting list arm (people who did not receive acupuncture until the end of treatment). Trials were combined using meta-analysis methods when the data allowed statistical pooling. Pooled effect sizes were calculated by random effects models. Results This review identified 7 trials (1768 participants); all were included in the meta-analysis. We found statistically significant differences in pain reduction post-intervention between SA or PA and routine care or a waiting list, with a standardized mean difference of -0.36 (95% CI -0.54 to -0.18; I2 statistic=16%; participants=624; studies=6) for the Visual Analog Scale and -0.35 (95% CI -0.49 to -0.20; I2 statistic=0%; participants=736; studies=1) for the Chronic Pain Grade Scale; however, no significant difference was observed between SA or PA and routine care or no treatment for post-intervention function. Conclusion Compared with routine care or a waiting list, SA or PA was more efficacious for pain relief post-intervention. Concluding that SA or PA is appropriate for acupuncture research would be premature. Guidelines evaluating SA or PA control methods are needed to determine the specific effect of acupuncture over placebo.

Abstract
BACKGROUND To investigate the effect of BC1036 on health-related quality of life (QOL) in subjects with persistent cough. The secondary objective was to investigate the effect of BC1036 on subjective cough severity. METHODS This was a randomised, multicentre, double-blind, placebo-controlled, parallel-group study in 289 subjects with persistent cough. Subjects received BC1036 or placebo twice daily for 14 days. The primary endpoint comprised cough-related QOL assessed using the validated Leicester Cough Questionnaire (LCQ) at Day 14. Secondary endpoints comprised the LCQ scores at Day 7 and Day 28, cough severity VAS scores at each visit and pulmonary function tests. RESULTS At baseline, mean total LCQ score in the BC1036 group was lower (i.e., worse QOL) than placebo (P<0.001), indicating significant between-group heterogeneity. Mean baseline-adjusted change in LCQ score at Day 14 was greater for BC1036 [mean (SD) 2.4±3.5] compared to placebo [mean (SD) score 2.2±3.0], but did not reach statistical significance (P=0.60). Mean cough severity VAS score decreased to a greater extent in the BC1036 group compared to placebo, but again the results were not statistically significant (-12.2±23.28 in BC1036 group and -11.0±21.34 in placebo group at Day 14, P=0.688). There was no significant change in pulmonary function measurements. The adverse event (AE) profile was similar in both groups. CONCLUSIONS This study showed that BC1036 was well tolerated and, although the primary endpoint did not achieve statistical significance, the magnitude of improvement was greater with BC1036 compared to placebo with respect to improving QOL and reducing cough severity. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov: NCT01656668.

Abstract
Due to its excellent biological and mechanical properties, silk fibroin has been intensively explored for tissue engineering and regenerative medicine applications. However, lack of translational evidence has hampered its clinical application for tissue repair. Here a silk fibroin film is developed and its translational potential is investigated for skin repair by performing comprehensive preclinical and clinical studies to fully evaluate its safety and effectiveness. The silk fibroin film fabricated using all green chemistry approaches demonstrates remarkable characteristics, including transmittance, fluid handling capacity, moisture vapor permeability, waterproofness, bacterial barrier properties, and biocompatibility. In vivo rabbit full-thickness skin defect study shows that the silk fibroin film effectively reduces the average wound healing time with better skin regeneration compared with the commercial wound dressings. Subsequent assessment in porcine model confirms its long-term safety and effectiveness for full-thickness skin defects. Finally, a randomized single-blind parallel controlled clinical trial with 71 patients shows that the silk fibroin film significantly reduces the time to wound healing and incidence of adverse events compared to commercial dressing. Therefore, the study provides systematic preclinical and clinical evidence that the silk fibroin film promotes wound healing thereby establishing a foundation towards its application for skin repair and regeneration in the clinic.

Abstract
Introduction: Pilot studies are meritorious for determining the feasibility of a definitive clinical trial in terms of conduct and potential for efficacy, but their possible applications for planning a future trial are not always fully realized. The purpose of this review was to estimate the extent to which pilot/feasibility studies: (i) addressed needed objectives; (ii) led to definitive trials; and (iii) whether the subsequent undertaking of a definitive trial was influenced by the strength of the evidence of outcome improvement. Methods: Trials published in the journal Clinical Rehabilitation, since its inception, were eligible if the word ‘pilot’ or ‘feasibility’ was specified somewhere in the article. A total of 191 studies were reviewed, results were summarized descriptively, and between-group effect sizes were computed. Results: The specific purposes of piloting were stated in only 58% (n = 110) of the studies. The most frequent purpose was to estimate the potential for efficacy (85%), followed by testing the feasibility of the intervention (60%). Only 12% of the studies were followed by a definitive trial; <4% of studies had a main study underway or a published study protocol. There was no relationship between observed effect size and follow-up of pilot studies, although the confidence intervals were very wide owing to small number of trials that followed on. Discussion: Labelling and reporting of pilot studies needs to be improved to be concordant with the recently issued CONSORT guidelines. Feasibility needs to be fully tested and demonstrated prior to committing considerable human and monetary resources.

Abstract
Background and Aim: Cocoa polyphenols have been shown to exhibit antioxidant properties in vivo and in vitro. This study aimed to determine whether commercially available chocolate could improve oxidant/antioxidant balance in medical students. Materials and Methods: Sixty students (30 males and 30 females) were given three different types of chocolate. Subjects were divided equally into three groups of 20 students (10 males and 10 females) as follows: (i) Dark chocolate group (DC), (ii) milk chocolate group (MC), and (iii) placebo group (PC). The placebo group was given white chocolate. Blood was drawn at baseline and after consumption of chocolate (40 g/day) for 2 weeks. Serum was analyzed for DNA/RNA oxidative damage, thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD), and glutathione peroxidase (GPX) enzymes. Descriptive analyses were conducted to determine the frequency distributions of the study variables. Means were compared across the study groups by one-way Analysis of Variance and within the same group by paired t-test. Results: Mean serum DNA/RNA damage, TBARS, SOD, and GPX enzymes compared between the groups revealed insignificant differences after 2 weeks of chocolate consumption (P = 0.46, 0.19, 0.11, and 0.06). Comparison within the same group also exhibited statistically insignificant differences in DNA/RNA damage in DC and MC groups (0.29 and 0.46, respectively); TBARS in DC and MC groups (0.11 and 0.19, respectively); SOD in DC and MC groups (0.06 and 0.11, respectively); and GPX in DC and MC groups (0.68 and 0.78, respectively). Conclusion: Consumption of 40 g of DC or MC daily for a period of 2 weeks appears to be an ineffective way of improving oxidant/antioxidant balance in medical students.

Abstract
Background There are numerous published controlled trials assessing the safety and the benefits of physical activity (PA) for child and adult cancer survivors. However, trials exclusively comprised of adolescent cancer survivors aged 13-19 years, who may experience different health and quality of life (QOL) effects as a function of their developmental status, are lacking. Rather, some trials have included both adolescent and child cancer survivors together. Objective The aim of this systematic review was to synthesize the findings from randomized controlled trails (RCTs) and controlled clinical trials (CCTs) investigating the effects of PA on health and QOL outcomes in samples comprised of >50% adolescent cancer survivors to summarize the current state of evidence, identify knowledge gaps, and highlight areas in need of additional research within this population. Methods Using a search strategy developed for this review, 10 electronic databases were searched for RCTs and CCTs that reported on the effects of PA on at least 1 health and/or QOL outcome in samples comprised of >50% adolescent cancer survivors. Results From the 2249 articles identified, 2 CCTs met the predetermined eligibility criteria and were included in this review. Combined, 28 adolescents (of 41 participants) who were receiving active treatment participated in the 2 studies reviewed. A total of 4 health and QOL outcomes (ie, bone mass, fatigue, grip strength, QOL) were assessed pre- and post-PA intervention. Conclusions On the basis of the 2 studies reviewed, PA appears to be safe and feasible. PA also shows promise to mitigate reductions in bone mass and might be a viable strategy to improve fatigue, grip strength, and QOL. High-quality controlled trials with larger samples exclusively comprised of adolescent cancer survivors that assess a wide range of outcomes are needed to determine the effects of PA on health and QOL outcomes in this population.

Abstract
Background The benefits of physical activity for child and adult cancer survivors have been summarized in previous systematic reviews. However, no review has summarized the evidence for adolescent cancer survivors. Objective This paper describes the design of a protocol to conduct a systematic review of published studies examining the effects of physical activity on health and quality of life outcomes for adolescent cancer survivors.
Methods Several guidelines informed the development of this protocol. The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines provided the structure by which to conduct and report the protocol; though some adaptations were made with regards to search terms, data synthesis, and evaluating the risk of bias. The Cochrane Handbook for Systematic Reviews of Interventions was used to guide research question development, search term selection, and the data extraction form. The Consolidated Standards of Reporting Trials guidelines helped inform the data extraction form. Lastly, the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews informed the data synthesis. Ten electronic databases were identified and a search strategy was developed using a combination of Medical Subject Headings terms and keywords that were developed by the authors and peer reviewed by a university librarian. Both authors independently screened eligible studies for final inclusion, and data were abstracted using a form developed by the research team. A decision was made to synthesize all data narratively. Results The review has now been completed, peer-reviewed, and accepted for publication in a forthcoming issue of JMIR Cancer.
Conclusions As this will be the first systematic review on this topic, outlining the protocol ensures transparency for the completed review. Further, this protocol illustrates how elements from several guidelines were incorporated to answer the research question (ie, what is the effect of physical activity on health and quality of life outcomes in adolescent cancer survivors). This flexible approach was necessary as a function of the paucity of available research on this topic.

Abstract
BACKGROUND As tau aggregation pathology correlates with clinical dementia in Alzheimer's disease (AD), a tau aggregation inhibitor (TAI) could have therapeutic utility. Methylthioninium (MT) acts as a selective TAI in vitro and reduces tau pathology in transgenic mouse models. OBJECTIVE To determine the minimum safe and effective dose of MT required to prevent disease progression on clinical and functional molecular imaging outcomes. METHODS An exploratory double-blind, randomized, placebo-controlled, dose-finding trial of MT (69, 138, and 228 mg/day) was conducted in 321 mild/moderate AD subjects. The primary outcome was change on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) at 24 weeks relative to baseline severity. Effect of treatment on regional cerebral blood flow decline was determined in a sub-study in 135 subjects. After 24 weeks, subjects were re-consented to enter sequential 6- and 12-month blinded extension phases. Registered with ClinicalTrials.gov (NCT00515333). RESULTS At 24 weeks, there were significant treatment benefits in two independent populations at the 138 mg/day dose: in moderate subjects on the ADAS-cog scale (treatment effect: -5.42 units, corrected p = 0.047) and two other clinical scales; in mild subjects on the more sensitive regional cerebral blood flow measure (treatment effect: 1.97%, corrected p < 0.001). With continued treatment for 50 weeks, benefit was seen on the ADAS-cog scale in both mild and moderate subjects. The delivery of the highest dose was impaired due to dose-dependent dissolution and absorption limitations. CONCLUSION The minimum safe and effective daily MT dose is 138 mg and suggests that further study of MT is warranted in AD.

Abstract
BACKGROUND We used growth mixture modeling (GMM) to identify subsets of patients with qualitatively distinct symptom trajectories resulting from treatment. Existing studies have focused on 12-week antidepressant trials. We used data from a concurrent antidepressant and psychotherapy trial over a 6-month period. METHOD Eight hundred twenty-one patients were randomized to receive either fluoxetine or tianepine and received cognitive-behavioral therapy, supportive therapy, or psychodynamic therapy. Patients completed the Montgomery-Åsberg depression rating scale (MADRS) at the 0, 1, 3, and 6-month periods. Patients also completed measures of dysfunctional attitudes, functioning, and personality. GMM was conducted using MADRS scores and the number of growth classes to be retained was based on the Bayesian information criterion. RESULTS Criteria supported the presence of four distinct latent growth classes representing gradual responders of high severity (42% of sample), gradual responders of moderate severity (31%), nonresponders (15%), and rapid responders (11%). Initial severity, greater use of emotional coping strategies, less use of avoidance coping strategies, introversion, and less emotional stability predicted nonresponder status. Growth classes were not associated with different treatments or with proportion of dropouts. CONCLUSIONS The longer time period used in this study highlights potential overestimates of nonresponders in previous research and the need for continued assessments. Our findings demonstrate distinct growth trajectories that are independent of treatment modality and generalizable to most psychotherapy patients. The correlates of class membership provide directions for future studies, which can refine methods to predict likely nonresponders as a means to facilitate personalized treatments.

Abstract
OBJECTIVES To evaluate the efficacy of two alcohol-free antimicrobial mouthrinses in reducing plaque and gingivitis compared to an alcohol-containing rinse and toothbrushing alone. METHODS One hundred and sixty healthy volunteers were enrolled in the randomized controlled trial. Participants were randomly and equally assigned to four groups: (i) toothbrushing + rinsing (0.06% CHX + 0.025% NaF, alcohol-containing rinse, positive control); (ii) toothbrushing + rinsing (0.06% CHX + 0.025% NaF, alcohol-free experimental rinse); (iii) toothbrushing + rinsing (0.06% CHX + 0.03% CPC + 0.025% NaF, alcohol-free experimental rinse); (iv) toothbrushing alone (negative control). At baseline, Quigley-Hein plaque index (QHI), modified proximal plaque index (MPPI), and papillary bleeding index (PBI) were recorded. All subjects brushed their teeth as usual during the study. Additionally, groups 1-3 rinsed twice daily. Eight weeks after baseline, indices were recorded again. anova with Bonferroni adjustment served for statistical analysis. RESULTS One hundred and fifty-five participants were included into final analysis (i: n = 39, 2: n = 39, 3: n = 37, 4: n = 40). Experimental rinses (ii, iii) reduced QHI and MPPI to a higher extent than the negative control (iv), whereas no significant difference to the positive control was found. QHI: (i) 36.6%, (ii) 32.3%, (iii) 36.8%, (iv) 21.6%; MPPI: (i) 11.9%, (ii) 12.2%, (iii) 13.6%, (iv) 3.5%. For PBI, no statistically significant difference was found between groups: (i) 80.2%, (ii) 77.8%, (iii) 76.5% and (iv) 78.8%. CONCLUSIONS With respect to QHI and MPPI, toothbrushing in combination with any rinse was more effective than toothbrushing alone. No statistically significant differences were found between the alcohol-free and the alcohol-containing control rinses.

Abstract
OBJECTIVE The purpose of this pilot study is to evaluate the feasibility of a physician-based cognitive behavioural (CBT) intervention for the treatment of depressive symptomatology among pregnant women. METHODS A pilot quasi-experimental trial was conducted in a family practice health centre in Toronto, Canada. Pregnant women (n = 42) were identified as having depressive symptomatology according to the Edinburgh Postnatal Depression Scale (EPDS) and allocated to either a control group (standard prenatal) or an intervention group. The intervention group received standard prenatal plus brief CBT, initiated between the 20th and 28th gestation week prenatal visit, from their obstetrical physician. Follow-up assessments were conducted at 38 weeks gestation and 6 weeks post-partum to examine depressive symptomatology, anxiety symptomatology, health-care utilization, medication utilization and overall treatment satisfaction. RESULTS The delivery of the CBT intervention was feasible, acceptable and produced relatively high rates of treatment adherence. Of the 21 women in the intervention group who evaluated their CBT experience, 90% were satisfied. Although not sufficiently powered to detect differences between the study groups, trends in the clinical outcome data favoured the intervention group where mean depression and anxiety scores were lower for those who received the brief CBT intervention than those in the control group. CONCLUSION Results suggest that brief physician-based CBT may be a feasible antenatal depression treatment option. The high satisfaction with, and acceptance of, the intervention by study participants and physicians suggests that a larger randomized trial is warranted.

AIM To test in a prospective controlled trial whether wheezing preschoolers presenting to the ED are different from the above in three different domains defining asthma: the atopic characteristics based on stringent asthma predictive index (S-API), the characteristics of bronchial hyper-responsiveness (BHR), and airway inflammation. METHODS The S-API was prospectively collected in 41 preschoolers (age 31.9 ± 17.4 months, range; 1-6 years) presenting to the ED with acute wheezing and compared to healthy preschoolers (n = 109) from our community (community control group). Thirty out of the 41 recruited preschoolers performed two sets of bronchial challenge tests (BCT)-(methacholine and adenosine) within 3 weeks and following 3 months of the acute event and compared to 30 consecutive ambulatory preschoolers, who performed BCT for diagnostic workup in our laboratory (ambulatory control group). On presentation, induced sputum (IS) was obtained from 22 of the 41 children. OUTCOMES Primary: S-API, secondary: BCTs characteristics and percent eosinophils in IS. RESULTS Significantly more wheezing preschoolers were S-API positive compared with the community control group: 20/41 (48.7%) versus 15/109 (13.7%, P < 0.001). All methacholine-BCTs-30/30 (100%) were positive compared with 13/14 (92.8%) in the ambulatory control group (P = 0.32). However, 23/27 (85.2%) were adenosine-BCT positive versus 3/17 (17.5%) in the ambulatory control group (P < 0.001). Diagnostic IS success rate was 18/22 (81.8%). Unexpectedly, 9/18 (50.0%) showed eosinophilia in the IS. CONCLUSIONS Wheezing preschoolers presenting to the ED is a unique population with significantly higher rate of positive S-API and adenosine-BCT compared with controls and frequently (50%) express eosinophilic airway inflammation.
