Eugenia uniflora Dentifrice for Treating Gingivitis in Children: Antibacterial Assay and Randomized Clinical Trial

Abstract School-age children are frequently at high risk for the onset of biofilm-dependent conditions, including dental caries and periodontal diseases. The objective of this study was to evaluate the clinical efficacy of a dentifrice containing Eugenia uniflora Linn. (Surinam cherry) extract versus a triclosan-based comparator in treating gingivitis in children aged 10-12 years. The in vitro antibacterial potential of the dentifrice was tested against oral pathogens (Streptococcus mutans, Streptococcus oralis and Lactobacillus casei). Then a phase-II clinical trial was conducted with 50 subjects aged 10-12 years, with clinical signs of gingivitis. The subjects were randomly assigned to the experimental group (n=25) and control group (n=25), in which participants used the experimental dentifrice and a triclosan-based fluoridated dentifrice (Colgate Total 12(r)), respectively. Clinical examinations assessed the presence of gingivitis (primary outcome) and biofilm accumulation (secondary outcome) using the Gingival-Bleeding Index (GBI) and Simplified Oral Hygiene Index (OHI-S), respectively, at baseline and after seven days of tooth brushing 3x/day. The data were analyzed using paired and unpaired t-test (GBI) and Wilcoxon and Mann-Whitney (OHI-S), with p≤0.05. The experimental dentifrice showed efficient antibacterial activity in vitro. In the clinical trial, a significant reduction in gingival bleeding was observed in both experimental and control groups (p<0.0001), with no statistical difference between them (p=0.178), although a small size effect was observed. Biofilm accumulation was only reduced in the control group (p=0.0039). In conclusion, E. uniflora dentifrice showed anti-gingivitis properties in children aged 10-12 years. Thus, it may be a potentially efficient and safe product to be used alternatively in preventive dental practice

ABSTRACT Objective: To evaluate the effects of Dramatic Therapeutic Play (DTP) technique on the degree of anxiety in hospitalized school-age children. Method: Randomized clinical trial performed in two hospitals ofSão Paulo, between May and October 2015. The intervention consisted of the application of DTP and the outcome was evaluated through the Child Drawing: Hospital (CD: H) instrument. The Wilcoxon-Mann Whitney, Corrected t, Fisher’s exact and Chi-square tests were used in the analysis. Statistical significance was set at 5%. Results: In all, 28 children participated in the study. The majority of children (75%) had a low anxiety score, with a mean CD: H score of 73.9 and 69.4 in the intervention and control groups respectively, and with no significant difference. Conclusion: Children submitted to DTP had the same degree of anxiety as those in the control group. However, it is suggested that new studies be performed with a larger number of children in different hospitalization scenarios.

OBJECTIVE: To evaluate the influence of customized insoles in the plantar pressure of diabetes patients with neuropathy in comparison to the sham group. METHODS: The work method, duly registered at the Registro Brasileiro de Ensaios Clínicos – REBEC (Clinical Trial Brazilian Register) (http://www.ensaiosclinicos.gov.br/) RBR-5NQK4K, includes a randomized, controlled, prospective, double-blinded clinical trial, with a sample of 46 volunteers that will be randomly randomized in a 1: 1 ratio to be referred to intervention and control groups. The intervention group will receive customized insoles, with a retrocapital bar and an ethyl vinyl acetate plaque (EVA) in the same shape as the retrocapital bar, in order to reduce the pressure on the forefoot. In the control group, flat insoles will be prepared without any therapeutic objective. This project was developed according to the standard protocol for randomized clinical trials (SPIRIT). Along with the clinical evaluation, demographic data of the sample will be collected to identify and confirm the presence of peripheral neuropathy, next, the pedobarographic will be evaluated, and finally, the patients will answer the FAAM questionnaire to assess foot functionality. The primary outcome will be analyzing pressure points in KiloPascal (kPa) in the patients’ feet through pedobarographic of the patients in the intervention and control groups. The secondary outcome will be the foot functionality in activities of daily living through the FAAM (Foot and Ankle Ability Measure), considering the volunteers in the initial evaluation, third and sixth months. FINAL CONSIDERATIONS: Mainly, results of this study will show whether there is a structural alteration in the analysis of the plantar pressure due to the continuous use of insoles and present the evaluation of whether the use of therapeutic insoles improves the foot functionality of the same users when compared to sham insoles.

Background. Retained hemothorax (RH) is a common problem in cardiothoracic and trauma surgery. We aimed to determine the optimum agitation technique to enhance thrombus dissolution and drainage and to apply the technique to a porcine-retained hemothorax. Methods. Three agitation techniques were tested: flush irrigation, ultrasound, and vibration. We used the techniques in a benchtop model with tissue plasminogen activator (tPA) and pig hemothorax with tPA. We used the most promising technique vibration in a pig hemothorax without tPA. Statistics. We used 2-sample t tests for each comparison and Cohen d tests to calculate effect size (ES). Results. In the benchtop model, mean drainages in the agitation group and control group and the ES were flush irrigation, 42%, 28%, and 2.91 ( P = .10); ultrasound, 35%, 27%, and .76 ( P = .30); and vibration, 28%, 19%, and 1.14 ( P = .04). In the pig hemothorax with tPA, mean drainages and the ES of each agitation technique compared with control (58%) were flush irrigation, 80% and 1.14 ( P = .37); ultrasound, 80% and 2.11 ( P = .17); and vibration, 95% and 3.98 ( P = .06). In the pig hemothorax model without tPA, mean drainages of the vibration technique and control group were 50% and 43% (ES = .29; P = .65). Discussion. In vitro studies suggested flush irrigation had the greatest effect, whereas only vibration was significantly different vs the respective controls. In vivo with tPA, vibration showed promising but not statistically significant results. Results of in vivo experiments without tPA were negative. Conclusion. Agitation techniques, in combination with tPA, may enhance drainage of hemothorax.

SUMMARY Uptake of tritiated lysine vasopressin ([3H]LVP) was studied in halved neural lobes of rats (which had been given either tap water (control group) or 2% (w/v) NaCl solution as drinking water for 4 days) as well as in slices of pig neural lobe. Uptake of radioactivity into the neural lobes was shown but analysis of the extracts of incubated lobes of both species by ion exchange chromatography showed that very little of it remained in the tissue as hormone. In addition, some radioactivity was associated with trichloroacetic acid-insoluble proteins. After 90 min of incubation, and after correction for the breakdown, the uptake of unchanged [3H]LVP, expressed as a tissue: medium ratio, was 0·14 ± 0·04 and 0·09 ± 0·03 (mean ± s.e.m.) for the saline-treated and control rats respectively, while the tissue: medium ratios for the breakdown product(s) were 6·47 ± 0·45 and 5·50 ± 0·36. The results suggest uptake of [3H]LVP into the cell with almost complete intracellular breakdown of the hormone.

There has been much debate over a direct role for progesterone (P4) in early bovine embryo development. While previous attempts to supplement bovine embryos in vitro with P4 produced results that vary and are often contradictory, this may be a response of administering P4 at inappropriate times. Therefore, the objective of these experiments was to determine if P4 could exert a direct effect on developing IVF-derived bovine embryos when administered at an appropriate time of embryo development. In Exp. I, IVF-derived bovine 8-cell embryos were randomly allotted to treatments: (1) control, CR1aa medium (n = 168); (2) vehicle, CR1aa + ETOH (0.01%) (n = 170); and (3) P4, CR1aa + ETOH + P4 (20 ng/mL in 50-μL droplet) (n = 173). In Exp. II, IVF-derived bovine 8-cell embryos were randomly allotted to treatments: (1) control, CR1aa medium (n = 160); (2) vehicle, CR1aa + DMSO (0.01%) (n = 180); and (3) P4, CR1aa + DMSO (0.01%) + P4 (20 ng/mL in 50-μL droplet) (n = 170). All embryos were evaluated on Days 6 to 9 post-insemination and rates calculated from 8-cell embryos. In Exp. I, ETOH tended to have a detrimental effect with significantly fewer (P < 0.05) embryos (53%) developing to the blastocyst stage on Day 7 compared with the control (62%) and P4 (71%) groups. At Day 7, significantly more embryos cultured in P4 (71%) developed to the blastocyst stage compared with the control group (62%). P4 treatment significantly increased the number of Grade 1 blastocysts (25%) on Day 7 compared with vehicle (15%) and control (17%) groups. At the end of culture, there were also significantly more Day 9 hatched blastocysts in the P4 group (33%) compared with vehicle (22%) and control (21%) groups. Supplementing P4 in the culture medium increased the rate of development, resulting in significantly more blastocysts (8%) on Day 6 and hatched blastocysts (21%) on Day 8 compared with vehicle (3% and 12%) and control (0% and 8%) groups, respectively. In Exp. II, there were no significant differences between treatment groups for Day 7 blastocysts (control 54%, DMSO 61%, P4 57%) and Day 9 hatched blastocysts (control 46%, DMSO 51%, P4 46%). However, there were significantly more Grade 1 blastocysts in the P4 group (22% and 36%) on Days 6 and 8 compared with vehicle (11% and 23%) and control (13% and 23%) groups, respectively. The lack of improvement in Day 7 blastocysts and Day 9 hatched blastocysts rates leads to further uncertainty in understanding the P4 vehicle interactions. In conclusion, the results of these two experiments indicate that P4 can exert a direct effect on the developing IVF-derived bovine embryo; however, due to P4 vehicle interactions; other inert vehicles need to be explored to further evaluate the direct effects of P4 on the developing bovine embryo.

The aim of this study was to evaluate in vitro the antimicrobial activity of glass ionomer (GIC) and zinc oxide-eugenol (ZOE) cements against Candida albicans. Standardized GIC and ZOE specimens were maintained in contact with C. albicans suspension (1 <FONT FACE=Symbol>´</FONT> 10(6) cells/ml) at 37°C for 24 h, 48 h or 7 days. A control group without any testing cement was included. After the incubation period, aliquots of 0.1 ml were plated on Sabouraud's agar, and then the number of colonies was counted. The results were expressed as values of logarithms of colony-forming units per milliliter (log CFU/mL) and were analyzed statistically by Kruskal-Wallis ANOVA. After 48 h of incubation, the ZOE group presented no growth of C. albicans. GIC and control groups presented similar mean values at all tested periods. According to the results obtained, it could be concluded that, under the experimental conditions, ZOE cement was more effective in vitro against C. albicans than GIC.

Abstract Background: Frozen shoulder (FS) is a prevalent musculoskeletal condition characterized by an often prolonged pain, disability and limited active and passive range of motion (ROM), however its management remains challenging yet. The objective of this trial was to compare the efficacy of acromioclavicular joint mobilization and physical therapy versus physical therapy in treatment of FS.Methods: In this single-blind randomized clinical trial, patients with diagnosis of FS were randomly allocated into mobilization + physical therapy (n=28) as experiment group, and physical therapy (n=28) as control group in two outpatient clinics of Tabriz University of Medical Sciences, Iran. The primary outcomes were self-reported shoulder pain-related disability measured by the Shoulder Pain and Disability Index (SPADI) questionnaire and goniometric assessment of shoulder ROM. The secondary outcome was the Visual Analogue Scale (VAS). Measures were performed at the baseline, immediately and one month after beginning the treatments.Results: Totally 51 patients with 25.73 ± 6.88 years old of age completed the study and their data were analyzed. VAS, SPADI, pain and disability improved more significantly in experiment group compared to control group immediately [-4.63 (-5.58- -3.67) vs. -2.22 (-2.96- -1.47), p<0.001; -23.08 (-28.63- -17.53) vs. -13.04 (-17.93- -8.16), p=0.008; -26.00 (-31.71- -20.29) vs. -16.35 (-23.39- -9.31), p=0.034 and -21.25 (-29.11- -13.39) vs. -10.98 (-17.53- -4.43), p=0.042, respectively] and one month after beginning of treatment [-5.58 (-6.45- -4.72) vs. -3.61 (-4.60- -2.62), p<0.001; -33.43 (-40.85- -26.01) vs. -20.03 (-26.00- -14.07), p=0.001; --42.83 (-49.09- -36.57) vs. -25.57 (-33.92- -17.21), p<0.001 and -27.55 (-36.19- -15.94) vs. -16.58 (-24.48- -8.67), p=0.041, respectively]. Active abduction ROM was also improved more significantly immediately after treatment in experiment group compared to control group [25.83 (11.45- 40.13) vs. 10.17 (1.02- 19.15), p=0.025], however there were no significant differences between two groups concerning other measured ROMs immediately and one month after treatment (all p>0.05). Conclusions: Acromioclavicular mobilization along with conventional physical therapy was more efficient in decreasing pain and disability and improving active abduction ROM compared to physical therapy in patients with FS. These findings would suggest a new therapeutic method for shoulder disorders with pain and disability.Trial registrationwww.irct.ir, IRCT20100605004104N7, registered 06.01.2019 (https://www.irct.ir/trial/35900)

Background: Passive immunotherapy with convalescent plasma (CP) is a potential treatment for COVID-19 for which evidence from controlled clinical trials is lacking. Methods: We conducted a multi-center, randomized clinical trial in patients hospitalized for COVID-19. All patients received standard of care treatment, including off-label use of marketed medicines, and were randomized 1:1 to receive one dose (250-300 mL) of CP from donors with IgG anti-SARS-CoV-2. The primary endpoint was the proportion of patients in categories 5, 6 or 7 of the COVID-19 ordinal scale at day 15. Results: The trial was stopped after first interim analysis due to the fall in recruitment related to pandemic control. With 81 patients randomized, there were no patients progressing to mechanical ventilation or death among the 38 patients assigned to receive plasma (0%) versus 6 out of 43 patients (14%) progressing in control arm. Mortality rates were 0% vs 9.3% at days 15 and 29 for the active and control groups, respectively. No significant differences were found in secondary endpoints. At inclusion, patients had a median time of 8 days (IQR, 6-9) of symptoms and 49,4% of them were positive for anti-SARS-CoV-2 IgG antibodies. Conclusions: Convalescent plasma could be superior to standard of care in avoiding progression to mechanical ventilation or death in hospitalized patients with COVID-19. The strong dependence of results on a limited number of events in the control group prevents drawing firm conclusions about CP efficacy from this trial.
