    Youth spend substantial time on social media, which can foster self-critical processes that increase risk of body dissatisfaction, disordered eating, and depressed mood. To date, there have been few investigations of interventions to decrease the negative impacts of social media engagement in adolescent boys and girls. This paper outlines the protocol for a cluster randomized controlled trial (RCT) of a four-lesson social media literacy program that was developed based on pilot results and aims to decrease body dissatisfaction, dietary restraint, and strategies to increase muscles. The RCT will be conducted with grades 7-8 students from Australian secondary schools. Using block randomization, grade levels within schools will be assigned to either the SoMe program (intervention) or health lessons as usual (control). Primary outcomes will be body satisfaction, dietary restraint, and strategies to increase muscles. Secondary outcomes will be self-esteem and depressed mood. Participants will complete assessments on four occasions – baseline, five-weeks post-baseline, and six- and 12-month post-baseline. Analyses will compare outcomes in the intervention compared to the control group. This study will be the first to implement a RCT design to evaluate the impact of a school-based social media literacy program designed to mitigate negative impacts of social media. Living with a visible difference (e.g., disfigurement) can compromise a child’s psychological wellbeing. Although some children can adjust well, others can develop a range of appearance-related issues such as social anxiety, low self-esteem, and body dissatisfaction. However, current research fails to confirm what factors contribute to appearance-related distress, and what factors buffer the consequences of living with a visible difference. Semi-structured qualitative interviews were conducted with 16 Australian specialist health professionals who care for children with visible differences. Interviews explored the type of appearance-related psychosocial concerns presented to a pediatric hospital, perspectives on the impact of appearance-related distress, as well as factors and processes that health professionals perceive influence adjustment. Data were subjected to inductive thematic analysis. Rich evidence was offered by health professionals, which demonstrated deep understanding of the psychological wellbeing of their patients. Three themes were identified Mind, Body, and Soul; Stages of Life; and Individual Differences. Findings highlighted the complexity of appearance-related distress, with individual differences in adjustment, and the powerful impact it can have on a child’s short and long-term psychosocial wellbeing. The importance of reaching consensus in the conceptualisation and measurement of psychological wellbeing is stressed, and key domains associated with adjustment are proposed. Caffeine is the most widely consumed psychotropic drug in the world, with numerous studies documenting the effects of caffeine on people’s alertness, vigilance, mood, concentration, and attentional focus. The effects of caffeine on creative thinking, however, remain unknown. In a randomized placebo-controlled between-subject double-blind design the present study investigated the effect of moderate caffeine consumption on creative problem solving (i.e., convergent thinking) and creative idea generation (i.e., divergent thinking). We found that participants who consumed 200 mg of caffeine (approximately one 12 oz cup of coffee, n = 44), compared to those in the placebo condition (n = 44), showed significantly enhanced problem-solving abilities. Caffeine had no significant effects on creative generation or on working memory. The effects remained after controlling for participants’ caffeine expectancies, whether they believed they consumed caffeine or a placebo, and changes in mood. Possible mechanisms and future directions are discussed. Anthracnose caused by Glomerella cingulata is one of the most devastating diseases of strawberry in Japan, particularly during its nursery period in the summer. In this study, we aimed to isolate and screen endophytic actinobacteria, to identify potential biocontrol agents capable of suppressing strawberry anthracnose. A total of 226 actinobacteria were successfully isolated from surface-sterilized strawberry tissues. In the first screening, 217 out of 226 actinobacteria isolates were studied for their suppression effect on strawberry anthracnose using a detached leaflet assay. It was discovered that isolates MBFA-172 and MBFA-227 markedly suppressed the development of anthracnose lesions. The efficacy of both isolates was then tested on two-month-old strawberry plug seedlings in a controlled environmental chamber. It was found that isolate MBFA-172 provided consistent disease suppression and was thus selected as a final candidate for further evaluation in a glasshouse experiment. Results showed that the severity as well as incidence rate of strawberry anthracnose was significantly reduced by treatment with isolate MBFA-172 compared with that of untreated control. Accordingly, the disease control efficacy provided by MBFA-172 was statistically comparable to the chemical fungicide propineb. A re-isolation experiment using a spontaneous thiostrepton-resistant mutated strain of isolate MBFA-172 revealed that it efficiently colonized the above-ground tissues of strawberry plants for at least three weeks after spray treatment. Using cultural, morphological, and physiological tests combined with 16S rRNA-based molecular analysis, MBFA-172 was identified as a moderately thermophilic Streptomyces thermocarboxydus-related species. Upon review, our results strongly indicated that MBFA-172 is a promising biocontrol agent for strawberry anthracnose. Inelastic mean free path (IMFP) was determined by electron energy loss spectroscopy (EELS) to estimate the accurate thickness of TEM thin foil using needle-shaped specimen. From EELS measurements performed for 99.99% Al, Si wafer and 99.99% Fe, linear relationships were confirmed between the thickness of the TEM thin foil and the ratio of the total intensity of EELS spectrum to the total intensity of zero-loss spectrum for all samples. By weighted least-square fitting, the IMFP was estimated to be 143-150 nm for Al, 159-165 nm for Si with amorphous layer, and 92-94 nm for Fe with the collection semi-angle β = 11.9 – 35.7 mrad, and accelerated voltage of 200 kV. Thus, the dependence of IMFP on β is not dominant. The accuracy depends on the roundness of the cross-section of the needle-shaped specimen, and is observed to be low in terms of percentage in this work. OBJECTIVES There have not been any longitudinal studies reported that chronic low back pain (CLBP) patients are at risk for stroke. Thus, in this study, we explored the association between CLBP and strokes. PATIENTS AND METHODS Data (2000∼2010) from the Taiwan National Health Insurance database were analyzed. We matched 10,308 CLBP patients with 20,616 propensity score-matched non-low back pain (NLBP) patients according to age, gender, index year and comorbidities. Covariates of age, gender, comorbidities, and usage of non-steroidal anti-inflammatory drugs (NSAIDs) were adjusted and analyzed. RESULTS The mean follow-up duration was 8 years. CLBP patients had higher risks of all stroke, hemorrhagic stroke, and ischemic stroke. The adjusted hazard ratios (aHRs) were 2.35 (95 % confidence interval (CI) 2.14-2.57, p less then 0.001), 1.55 (95 % CI 1.16-2.06, p = 0.003), and 2.41 (95 % CI 2.18-2.66, p less then 0.001), respectively. After adjusting and analyzing the NSAIDs used for the varied duration in the CLBP patients, we did not observe any impacts of such NSAIDs used on the association of CLBP with strokes. The association between CLBP and ischemic stroke was most prominent in the patients less than 50 years old with aHR 3.56 (CI 2.74∼4.61, p less then 0.001). CONCLUSION CLBP was associated with increased risk of strokes, especially ischemic stroke, and the association was most prominent in patients less than 50 years old. Further large prospective studies on detailed lifestyle-related factors and qualitative pain assessment are needed to clarify the causal relationship between CLBP and stroke. PURPOSE Among patients with epilepsy, sleep disturbances can worsen seizure control. This prospective open-label study determined the effect of the antiepileptic drug perampanel on sleep architecture in patients with refractory epilepsy. METHODS Adult patients with refractory epilepsy received add-on perampanel, starting at 2 mg/day at bedtime, increased by 2 mg after 2 weeks and then monthly until the target dose of 4-8 mg/day was reached. The median dose of perampanel used was 6 mg (SD 1.2). Polysomnographic (PSG) recordings were scheduled 1 week before starting perampanel and the control PSG after 12 weeks under perampanel treatment and at least 4 weeks on stable perampanel dose; patients completed the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI) questionnaires. The main endpoints were change from baseline in the ESS and PSQI scores, and PSG variables. RESULTS Of 25 patients included (aged 18-65 years, 56 % female) only 17 completed the study. Perampanel caused a modest decrease from baseline in mean ESS score (n = 13 patients; p = 0.126) and PSQI score (n = 12 patients; p = 0.127). Treatment significantly improved sleep parameters (n = 17 patients) including total sleep time (p = 0.037), sleep latency (p = 0.022), sleep efficiency (p = 0.015), sleep maintenance index (p = 0.005), wake time after sleep onset (p = 0.015), and duration of N3 sleep stage (p = 0.026). Patients with altered sleep efficiency parameters at baseline showed a significant increase in sleep maintenance index (p = 0.015), and 77.8 % achieved sleep efficiency >85 % (p = 0.016 vs baseline). CONCLUSION Perampanel improved sleep architecture in patients with focal refractory epilepsy without worsening daytime sleepiness. BACKGROUND International comparisons found that depression prevalence ranged from 18.3% (China) to 51.5% (Zambia) among school students in some low- and middle-income countries (LMICs). The evidence base for treatment of adolescent depression in LMICs is limited and inadequate. Moreover, most treatment interventions are developed in high income countries and the effectiveness of these treatments in LMICs is largely unknown. METHOD Randomized controlled trials, including cluster-randomized trials that have been implemented in LMICs to reduce adolescent depression, were examined in this systematic review and meta-analysis. Only one-time point (3 months or close to 3 months) of the outcome measures was chosen to evaluate effectiveness of interventions. RESULTS Studies that used cognitive-behavioral therapy reduced depressive symptoms more effectively than other treatments with standardized mean difference (SMD) = -1.27, (95% CI -2.19 to -0.35). Microfinance/economic interventions also reduced depression in adolescents with SMD = – 0.35, (95% CI -0.71 to 0.01) and Interpersonal therapy was used in three studies and depressive symptoms reduced by SMD = -0.23, (95% IC -0.60 to 0.13). Moreover, complex psychotherapeutic interventions that used integrated techniques showed a reduction in depression with SMD = -0.23, (95% IC -0.33 to -0.14) as well. CONCLUSIONS Across twenty-eight studies, the evidence showed that cognitive behavioral therapy that delivered by nurses, social workers and counselors at community-based settings were more effective treatments in decreasing adolescent depression in LMICs. Future studies should implement these universal treatment approaches to identify accessible, feasible, affordable and sustainable depression treatments in the countries with less available resources.
