Demonstrating clinical utility for diagnostic tests and securing coverage and reimbursement requires high quality and, ideally, randomized controlled trial (RCT) data. Traditional RCTs are often too costly, slow, and cumbersome for diagnostic firms. Alternative data options are needed. We evaluated four RCTs using virtual patients to demonstrate clinical utility. Each study used a similar pre-post intervention, two round design to facilitate comparison. Representative samples of physicians were recruited and randomized into control and intervention arms. All physicians were asked to care for their virtual patients during two assessment rounds, separated by a multi-week time interval. Between rounds, intervention physicians reviewed educational materials on the diagnostic test. All physician responses were scored against evidence-based care criteria. RCTs using virtual patients can demonstrate clinical utility for a variety of diagnostic test types, including: (1) an advanced multi-biomarker blood test, (2) a chromosomal microarray, (3) a proteomic assay analysis, and (4) a multiplex immunofluorescence imaging platform. In two studies, utility was demonstrated for all targeted patient populations, while in the other two studies, utility was only demonstrated for a select sub-segment of the intended patient population. Of these four tests, two received positive coverage decisions from Palmetto, one utilized the study results to support commercial payer adjudications, and the fourth company went out of business. RCTs using virtual patients are a cost-effective approach to demonstrate the presence or absence of clinical utility.

The Impact

Aims: To describe the rationale, study design, population and dietary compliance in a randomized controlled trial (RCT) investigating the effect of fatty fish on cognitive performance and mental health in adolescents. Method: In the Fish Intervention Studies-TEENS (FINS-TEENS) study we individually randomized 478 adolescents (14–15-year-olds) from eight secondary schools in Norway to receive school meal lunches with fatty fish or meat or n-3 supplements three times a week for 12 weeks. Demographic factors, psychological tests and biological measures were collected pre-and post-intervention. Duplicate portions of lunch meals were collected and individual intake recorded throughout the study. Results: In total, 481 out of 785 adolescents (61%) agreed to participate and 34 (7%) dropped out. Breakfast consumption was the only group difference in background characteristics. Analyses of selected nutrients in the lunch meals showed higher levels of n-3 fatty acids, vitamin D and n-6 fatty acids in the fish compared to the meat meals. Dietary compliance (score 0–144) revealed that the intake in the Fish group (mean = 59, standard deviation (SD) = 35) were lower than in the Meat group (mean = 83, SD = 31, p < 0.01) and Supplement group (mean = 105, SD = 25, p < 0.01). Conclusions: The results show that it is possible to conduct a RCT with fatty fish in a school-based setting. The results also emphasize the importance of collecting detailed records of dietary compliance, as this information is important when interpreting and analysing the outcome of dietary interventions.

Background. Exercise is increasingly becoming recognized as an important adjunct to medications in the clinical management of Parkinson’s disease (PD). Boxing and sensory exercise have shown immediate benefits, but whether they continue beyond program completion is unknown. This study aimed to investigate the effects of boxing and sensory training on motor symptoms of PD, and whether these benefits remain upon completion of the intervention. Methods. In this 20-week double-blinded randomized controlled trial, 40 participants with idiopathic PD were randomized into 2 treatment groups, (n = 20) boxing or (n = 20) sensory exercise. Participants completed 10 weeks of intervention. Motor symptoms were assessed at (week 0, 10, and 20) using the Unified Parkinson’s Disease Rating Scale (UPDRS-III). Data were analyzed using SPSS, and repeated-measures ANOVA was conducted. Results. A significant interaction effect between groups and time were observed F(1, 39) = 4.566, P = .036, where the sensory group improved in comparison to the boxing group. Post hoc analysis revealed that in comparison to boxing, the effects of exercise did not wear off at washout (week 20) P < .006. Conclusion. Future rehabilitation research should incorporate similar measures to explore whether effects of exercise wear off post intervention.

Healthy lifestyles should be encouraged in the workplace through the occupational health teams of the companies. The objective of the present study was to evaluate the adherence to a lifestyle intervention carried out in university employees during the COVID-19 pandemic and its impact on health-related quality of life (HrQoL). A randomized controlled trial following the CONSORT guidelines was performed, consisting of three supervised interventions lasting for 18 weeks: an educational intervention on healthy habits, a nutritional intervention, and a telematic aerobic and strength exercise intervention. Lifestyle and HrQoL were analyzed six months post-intervention to assess adherence. Twenty-three middle-aged participants completed the study. The intervention group significantly improved their lifestyle according to the Health Promoting Lifestyle Profile II questionnaire, especially in the categories of Health Responsibility, Physical Activity, and Nutrition, with a large effect size. Sitting time was reduced by 2.5 h per day, with a moderate effect size. Regarding HrQoL, the intervention group showed a clinically significant improvement in the Physical Component Summary. Despite the lockdown and the mobility restrictions caused by the COVID-19 pandemic, this intervention performed on university employees achieved adherence to a healthier lifestyle and improved their HrQoL, which is of great clinical relevance.

Abstract Introduction: Equol, an isoflavone derivative whose chemical structure is similar to estrogen, is considered as a potentially effective agent for relieving climacteric symptoms, for the prevention of the lifestyle-related diseases, and for aging care in post-menopausal women. We investigated the effect of an equol-containing supplement on metabolism and aging, and climacteric symptoms, with respect to internally-produced equol in post-menopausal women.Methods: A single center, randomized controlled trial (registration number: UMIN000030975) on 57 post-menopausal Japanese women (mean age: 56±5.37 years), was conducted. Twenty-seven women received the equol supplement, while the remaining received Control. Metabolic and aging-related biomarkers were compared before and after the 3-month intervention. Climacteric symptoms were assessed every month using a validated self-administered questionnaire in Japanese post-menopausal women. Results: Three months post intervention, the treatment group showed significant improvement in climacteric symptoms, when compared to the Control group (81% vs. 53% respectively, p=0.045). We did not observe any beneficial effect on metabolic and aging-related biomarkers in the intervention group. However, in certain populations significant improvement in skin auto-fluorescence, which is a measurement of AGE skin products, and visceral fat area was observed, especially among equol producers. Conclusion: Women receiving equol supplement showed improved climacteric symptoms. This study offered a new hypothesis that there may be a synergy between supplemented equol and endogenously-produced equol to improve skin aging and visceral fat in certain populations.

Abstract Procedures and actions such as injections and immobilization cause pain and distress to children. In the pediatric field, there is a need for interventions and support to alleviate the pain and distress caused by such medical procedures. In recent years, the introduction of robots as a means of distraction has begun to be attempted. In this study, we conducted a non-randomized controlled trial to examine the effect of intervention using ‘aibo’, a dog-like robot which has artificial intelligence (AI), to promote distraction in children after vaccination. As a result, 57 children (32 in the intervention group) participated in the study. Results of a t-test with the control group showed that the intervention group using aibo had significantly less pain following the post-vaccination intervention than the control group using stuffed dog (Face Scale, t(55) = 2.582, p = .0125; Behavioral Observation Scale, t(55) = 2.772, p = .00759). The results support the hypothesis that the aibo intervention group will be less distressed and able to calm down more quickly after vaccination than the control group. Conclusion : AI-powered aibo interventions that allow for interactive interaction can be an effective distraction method during painful procedures such as vaccinations.

The Difference

Abstract A neonatal intensive care unit (NICU) can be an extremely stressful environment for infants receiving complex medical care at a pediatric facility. Music therapy can help address the stressful environment by increasing comfort and relaxation as well as decreasing a patient’s physiological response of heart rate and respiratory rate. A randomized controlled trial was completed, examining the effects of 2 guitar accompaniment patterns on infants (an arpeggiated pattern and a bass/chord pattern) in a NICU. There were 180 infants enrolled with mean chronological ages of 7.4 ± 6.1 weeks and postmenstrual ages (gestational age at birth + their chronological age) of 39.8 ± 7.9 weeks. All subject enrollees participated in a 12-minute initial music therapy session. Outcome measures included heart rate, respirations, and comfort responses. The results of the research study demonstrated that the arpeggiated guitar pattern had a lower mean heart rate and respiratory across all 3 data points (pre, during, and post intervention); however, the difference in means between the 2 accompaniment pattern groups was not statistically significant. Using the Neonatal Infant Pain Scale (NIPS) to measure comfort response, the results demonstrated no difference between the 2 group accompaniment patterns. Although the results show no significant differences among accompaniment pattern groups, the researchers describe the clinical significance that supports the use of both accompaniment patterns as suitable interventions for infants in the NICU receiving music therapy intervention.

Abstract Objectives This interventional study will investigate the effect of daily use of a mindfulness app on measures of participant anxiety, well-being, and perceived outlook during the COVID-19 pandemic, by comparing pre-intervention survey responses to post-intervention survey responses. Trial design Randomized, controlled trial with parallel assignment. Adults will be assigned either to daily use of a meditation app for 30 days or to a control group (no usage of meditation app) with a 1:1 equivalence allocation ratio. Participants Inclusion Criteria: Participants must be 18 or older, have a smartphone, able to download apps to their smartphone, must be fluent in the English language, able to complete surveys on their own, and must be in the United States for the duration of the study. Exclusion Criteria: Current regular use of a mindfulness or meditation app, regular practice of mindfulness or meditation, regular therapy sessions, inability to complete surveys independently, or any mental health restrictions that would prevent participation. All data will be collected through the Insight Timer Meditation App and Google Forms. This trial is being conducted through the Lake Erie College of Osteopathic Medicine in Erie, PA, with all data collected digitally. Intervention and comparator Intervention: Participants will be sent a link to a pre-intervention survey prior to first use of the mindfulness app. Participants will be instructed to use the Insight Timer app for 10 minutes daily for 30 days. At the end of the 30-day intervention period, participants will be sent a link for the post-intervention survey. Two months after the conclusion of the 30-day intervention period, participants will be sent a link for another post-intervention survey. Comparator: Participants will receive the same surveys, but will not use any mindfulness app for the 30-day intervention period. After this 30-day period, participants are invited to use the Insight Timer app if they so choose. Main outcomes The main outcomes are (1) anxiety as assessed by survey questions adapted from the GAD7, comparing pre-intervention to post-30-days of app usage and (2) well-being as assessed by survey questions adapted from the WHO-5, comparing pre-intervention and post-30-days of app usage. Randomization Participants will be allocated to interventions via a block random sequence generator with a 1:1 allocation ratio in blocks of 8. Blinding (masking) No masking is being used in this study (open label). Numbers to be randomized (sample size) Approximately 75 participants will be randomized to each group, with an estimated enrollment of 150 participants. Trial status This study is protocol version number 27-126 and was approved on May 10, 2020. Recruitment began on August 19, 2020 and will end February 28, 2021.

Superiority Trial

AbstractThe study, a two-arm, randomized controlled, parallel group, superiority trial, aimed to evaluate the implementation and effectiveness of a 12-month one-to-one volunteer mentoring program designed to improve behavioral and emotional outcomes in children aged 5 to 11 years who have teacher- and parent/carer-reported behavioral difficulties. Participants were 246 children (123 intervention, 123 control; mean age 8.4 years; 87% boys) in five sites in London, UK, scoring in the “abnormal” range on the teacher-rated Strengths and Difficulties Questionnaire (SDQ) Total Difficulties measure and in the “borderline” or abnormal range on the parent-rated SDQ Total Difficulties measure. Randomization on a 1:1 ratio took place using a computer-generated sequence and stratifying by site. Data collectors and statisticians were blind to participant allocation status. Outcome measures focused on parent- and teacher-rated child behavior and emotions, and child-rated self-perception and hope. Intention-to-treat analysis on all 246 randomized participants (using imputed data where necessary) showed that at post-intervention (16 months after randomization), there were no statistically significant effects on the primary outcome—parent-rated SDQ Total Difficulties (adjusted standardized mean difference = − 0.12; 95% CI: −0.38 to 0.13; p = 0.33)—or any secondary outcomes. Results from complier average causal effect (CACE) analysis using the primary outcome indicated the intervention was not effective for children who received the recommended duration of mentoring. Exploratory analyses found no sub-group effects on the primary outcome. The article concludes that the mentoring program had no effect on children’s behavior or emotional well-being, and that program content needs revising to satisfactorily address key risk and protective factors.
