Objective: The objective of this single-use, examiner-blind clinical study, was to evaluate the efficacy of a newly designed Colgate Actibrush (battery-powered toothbrush) relative to the Crest SpinBrush (battery-powered toothbrush) for the removal of supragingival plaque.
Methodology: This study included the assessment of plaque removal via the comparison of pre- and post-brushing plaque levels. A total of 80 adult male and female subjects from the central New Jersey area reported to the clinical facility for a baseline (pre-brushing) plaque examination after having refrained from all oral hygiene procedures and chewing gum for 24 hours, and from eating, drinking, or smoking for four hours. Subjects were entered into the study and stratified into two balanced groups based on their baseline plaque scores. Subjects were instructed to brush their teeth for one minute under supervision with their assigned toothbrush and a commercially available toothpaste (Colgate Cavity Protection Great Regular Flavor Fluoride Toothpaste), after which they were once again evaluated for supragingival plaque (post-brushing).
Results: All 80 subjects complied with the protocol, and completed the single-use clinical study. The subjects assigned to the Colgate Actibrush group exhibited a statistically significant 44.5% greater whole-mouth plaque reduction after a single brushing than did those subjects assigned to the Crest SpinBrush group. Relative to the pre-brushing baseline scores, the Colgate Actibrush group exhibited a statistically significant 63.7% reduction in whole-mouth plaque removal.
Conclusion: The results of this single-use, examiner-blind, clinical study support the conclusion that the newly designed Colgate Actibrush provides significantly greater efficacy for the removal of supragingival plaque than does the Crest SpinBrush.

Clinical trials (CTs) often suffer from small sample sizes due to limited budgets and patient enrollment challenges. Using historical data for the CT data analysis may boost statistical power and reduce the required sample size. Existing methods on borrowing information from historical data with right-censored outcomes did not consider matching between historical data and CT data to reduce the heterogeneity.

A recent study design for clinical trials with small sample sizes is the small n, sequential, multiple assignment, randomized trial (snSMART). An snSMART design has been previously proposed to compare the efficacy of two dose levels versus placebo. In such a trial, participants are initially randomized to receive either low dose, high dose or placebo in stage 1.

Introduction: T regulatory cells (Tregs) inversely correlate with disease progression in Amyotrophic Lateral Sclerosis (ALS) and fast-progressing ALS patients have been reported to exhibit dysfunctional, as well as reduced, levels of Tregs. This study aimed to evaluate the longitudinal changes in Tregs among ALS patients, considering potential clinical and biological modifiers of their percentages and concentrations. Additionally, we explored whether measures of ALS progression, such as the decline over time in the revised ALS Functional Rating Scale (ALSFRS-r) or forced vital capacity (FVC) correlated Treg levels and whether Treg phenotype varied during the course of ALS.

Objective: The objective of this study is to compare the effectiveness of low-load blood flow restriction training (LL-BFRT) to heavy-load resistance training (HL-RT) in male collegiate athletes with chronic non-specific low back pain (CNLBP).
Methods: Twenty-six participants were randomly assigned to LL-BFRT ( = 13) or HL-RT ( = 13). All participants supervised exercises (deep-squat, lateral pull-down, bench-press and machine seated crunch) cycled 4 times per week for 4 weeks (16 sessions).
