Acute sleep hygiene strategy improves objective sleep latency following a late-evening soccer-specific training session: A randomized controlled trial
<p>The aim of this study was to evaluate the effects of sleep hygiene (SH) education on sleep quality in soccer players after a late-evening small-sided-game (SSG) training session. Twenty-nine non-professional players were recruited and allocated to either an experimental group (EG, n=17) that received SH education, or a control group (CG, n=12). SSG consisted of 3´4 minutes in a 4vs4, with 3 minutes of recovery and was performed at 8.00 p.m. Sleep quality was monitored via actigraphy and sleep diary entries before (PRE) and two nights after (POST1, POST2) the SSG. Sleep latency (SL) differed between the two groups at POST1 (4.9±5.4 vs. 15.5±16.1 for EG and CG, respectively; p=0.017, effect size [ES]=2.0); SL values were lower at POST1 compared to PRE for the EG (-47%; p=0.021, ES=0.6). Subjective sleep quality was better in the EG than the CG at POST1 (8.6±1.0 vs. 7.1±2.0 for EG and CG, respectively; p=0.016, ES=0.9) with a significant improvement over PRE values (+11.0%, p=0.004, ES=0.8). Despite SL and subjective sleep quality were similar in PRE and POST2, no significant deterioration in such sleep indices over time was observed for EG. No other objective sleep indices were influenced by late-evening training or SH practices implemented by the EG. Soccer players may benefit from acute SH strategies to reduce the time to sleep onset after late-evening training sessions.</p>

Data from: Effect of aerobic exercise on cognition in younger adults: a randomized clinical trial
Objective: To determine efficacy of aerobic exercise for cognitive function in younger healthy adults. Methods: In a randomized, parallel-group, observer-masked, community-based clinical trial, 132 cognitively normal individuals aged 20-67 with below median aerobic capacity were randomly assigned to one of two 6-month, four-times-weekly conditions: aerobic exercise and stretching/toning. Efficacy measures included: aerobic capacity; cognitive function in six domains (executive function, episodic memory, processing speed, language, and attention), everyday function, BMI and cortical thickness. Results: Aerobic capacity increased significantly (β=2.718; p=0.003), and BMI decreased significantly (β=-0.596; p=0.013) in the aerobic exercise but not in the stretching/toning condition. Executive function improved significantly in the aerobic exercise condition; this effect was moderated by age (β=0.018 s.d. per year; p=0.028). At age 40 the executive function measure increased by 0.228 s.d. (95% CI: 0.007 - 0.448), and by 0.596 s.d. (95% CI: 0.219 - 0.973) at age 60. Cortical thickness increased significantly in the aerobic exercise group in a left frontal region and did not interact with age. Controlling for age and baseline performance, individuals with at least one APOE ε4 allele showed less improvement in executive function with aerobic exercise (β=0.5129, 95%CI 0.0381 to 0.988; p=0.0346). Conclusions: This randomized clinical trial demonstrates the efficacy of aerobic exercise for cognition in adults age 20 – 67. The effect of aerobic exercise on executive function was more pronounced as age increased, suggesting that it may mitigate age-related declines. Increased cortical thickness suggests that aerobic exercise contributes to brain health in individuals as young as age 20. Clinicaltrials.gov Identifier: NCT01179958 Classification of evidence: This study provides Class II evidence that for adults age 20-67 with below median aerobic capacity, aerobic exercise significantly improves executive function but not other measures of cognitive function.
Data from: MHC class I diversity predicts non-random mating in Chinese alligators (Alligator sinensis)
The major histocompatibility complex (MHC) plays numerous important roles in kin recognition, pathogen resistance, and mate selection. Research in fish, birds, and mammals have suggested that individuals optimize MHC diversity, and therefore offspring fitness, when choosing mates. In reptiles, however, it is unclear whether female mate choice is based on genome-wide genetic characteristics such as microsatellites DNA loci, on particular functional trait loci (e.g., MHC) or on both, and MHC effects on mate choice remain relatively under-studied. Herein, we used 13 microsatellite loci and two MHC class I loci to investigate female mate choice of Chinese alligators (Alligator sinensis) in the semi-natural condition. We also determined correlations between the MHC genotype of breeding males and male reproductive success. We found that MHC-heterozygous males harbour a greater reproductive success, which possibly is the reason that those males were more preferred by the females than MHC-homozygous males. Furthermore, MHC class I amino-acid distance and functional distance of true mating pairs were higher compared with that of randomly sampled pairs. Analysis of microsatellites revealed that despite mate choice, individuals did not completely avoid inbreeding. These findings are the first evidence of MHC-associated mate choice in Chinese alligators, and they suggest that females may adopt different mating strategies after assessing MHC characteristics of potential mates.
Data from: INTREPAD: a randomized trial of naproxen to slow progress of presymptomatic Alzheimer disease
Objective: Evaluate the safety and efficacy of low-dose naproxen for prevention of progression in pre-symptomatic AD among cognitively intact persons at-risk. Methods: INTREPAD, a two-year double-masked pharmaco-prevention trial, enrolled 195 AD family history-positive elderly (mean age 63 years) screened carefully to exclude cognitive disorder. These were randomized 1:1 to naproxen sodium 220mg twice-daily or placebo. Multimodal imaging, neurosensory, cognitive and (in ~50%) CSF biomarker evaluations were performed at Baseline, 3, 12, and 24 months. A modified intent-to-treat analysis considered 160 participants who remained on-treatment through their first follow-up examination. The primary outcome was rate of change in a multimodal composite pre-symptomatic Alzheimer Progression Score (APS). Results: Safety: Naproxen-treated individuals showed a clear excess of adverse events. Efficacy: Among treatment groups combined, the APS increased by 0.101 points/year (S.E = 0.014; P < 10-5), but rate of change showed little difference by treatment assignment (0.017 points/year). The treatment-related slope ratio of 1.10 (95% Confidence Interval 0.588–2.04) suggested that naproxen does not reduce the rate of APS progression by more than 41%. Secondary analyses revealed no notable treatment effects on individual CSF, cognitive, or neurosensory biomarker indicators of progressive pre-symptomatic AD. Conclusions: In cognitively intact individuals at-risk, sustained treatment with naproxen sodium 220 mg twice-daily increases frequency of adverse health effects but does not reduce apparent progression of pre-symptomatic AD. Classification of Evidence: This study provides Class I evidence that, for people who are cognitively intact, low-dose naproxen does not significantly reduce progression of a composite indicator of pre-symptomatic AD.
Data from: Random heteropolymers preserve protein function in foreign environments
The successful incorporation of active proteins into synthetic polymers could lead to a new class of materials with functions found only in living systems. However, proteins rarely function under the conditions suitable for polymer processing. On the basis of an analysis of trends in protein sequences and characteristic chemical patterns on protein surfaces, we designed four-monomer random heteropolymers to mimic intrinsically disordered proteins for protein solubilization and stabilization in non-native environments. The heteropolymers, with optimized composition and statistical monomer distribution, enable cell-free synthesis of membrane proteins with proper protein folding for transport and enzyme-containing plastics for toxin bioremediation. Controlling the statistical monomer distribution in a heteropolymer, rather than the specific monomer sequence, affords a new strategy to interface with biological systems for protein-based biomaterials.
Data from: Mobile phone reminders and peer counseling improve adherence and treatment outcomes of patients on ART in Malaysia: a randomized clinical trial
Background: Adherence to treatment remains the cornerstone of long term viral suppression and successful treatment outcomes among patients receiving Antiretroviral Therapy (ART). Objective(s): Evaluate the effectiveness of mobile phone reminders and peer counseling in improving adherence and treatment outcomes among HIV positive patients on ART in Malaysia. Methods: A single-blind, parallel group RCT conducted in Hospital Sungai Buloh, Malaysia in which 242 adult Malaysian patients were randomized to intervention or control groups. Intervention consisted of a reminder module delivered through SMS and telephone call reminders by trained research assistants for 24 consecutive weeks (starting from date of ART initiation), in addition to adherence counseling at every clinic visit. The length of intended follow up for each patient was 6 months. Data on adherence behavior of patients was collected using specialized, pre-validated Adult AIDS Clinical Trial Group (AACTG) adherence questionnaires. Data on weight, clinical symptoms, CD4 count and viral load tests were also collected. Data was analyzed using SPSS version 22 and R software. Repeated measures ANOVA, Friedman's ANOVA and Multivariate regression models were used to evaluate efficacy of the intervention. Results: The response rate after 6 months follow up was 93%. There were no significant differences at baseline in gender, employment status, income distribution and residential location of respondents between the intervention and control group. After 6 months follow up, the mean adherence was significantly higher in the intervention group (95.7; 95% CI: 94.39–96.97) as compared to the control group (87.5; 95% CI: 86.14–88.81). The proportion of respondents who had Good (>95%) adherence was significantly higher in the intervention group (92.2%) compared to the control group (54.6%). A significantly lower frequency in missed appointments (14.0% vs 35.5%) (p = 0.001), lower viral load (p = 0.001), higher rise in CD4 count (p = 0.017), lower incidence of tuberculosis (p = 0.001) and OIs (p = 0.001) at 6 months follow up, was observed among patients in the intervention group. Conclusion: Mobile phone reminders (SMS and telephone call reminders) and peer counseling are effective in improving adherence and treatment outcomes among HIV positive patients on ART in Malaysia. These findings may be of potential benefit for collaborative adherence planning between patients and health care providers at ART commencement.
Data from: Video education versus face-to-face education on inhaler technique for patients with well-controlled or partly-controlled asthma: a phase IV, open-label, non-inferiority, multicenter, randomized, controlled trial
Background: Education on inhaler technique is critical for effective asthma treatment. However, traditionally used face-to-face education is a time-consuming, costly, and often laborious. The current study evaluated the efficacy of a newly developed video-based inhaler technique education method. Methods: A total of 184 subjects with well-controlled or partly-controlled asthma were enrolled from 12 hospitals in South Korea from 30 November 2015 to 01 June 2016. Subjects were randomly divided into two groups in a 1:1 ratio; a control group that received face-to-face education, and an study group that received video education. All subjects received fluticasone propionate plus salmeterol xinafoate (Fluterol® 250/50 inhalation capsules) for 12 weeks. The primary outcome measure was forced expiratory volume in the 1st second (FEV1) at 12 weeks. The secondary outcome measures were change in FEV1 at 4 weeks, change in asthma control test (ACT) score, and changes in various inhaler technique parameters. These measures were assessed with a non-inferiority margin of 10% between the control group and the study group. Results: FEV1 was significantly improved at 12 weeks in the control group and the study group. After adjustment, FEV1 improvement was not significantly inferior in the study group compared to the control group. The secondary outcome measures, including change in FEV1 at 4 weeks, ACT score, and various parameters pertaining to inhaler technique and satisfaction at 4 and 12 weeks did differ not significantly in the two groups. In subgroup analysis of elderly subjects and subjects with well-controlled asthma, FEV1 was significantly improved at 12 weeks in the study group but not the control group. Conclusion: The newly developed video education technique investigated functioned as a suitable substitute for face-to-face education on inhaler technique (dry powder inhalation capsule) in patients with stable asthma, particularly in elderly patients and patients with well-controlled asthma.
