BACKGROUND ImpulsePal is a theory-driven (dual-process), evidence-informed, and person-centered smartphone app intervention designed to help people manage impulsive processes that prompt unhealthy eating to facilitate dietary change and weight loss. OBJECTIVE The aims of this study were to (1) assess the feasibility of trial procedures for evaluation of the ImpulsePal intervention, (2) estimate standard deviations of outcomes, and (3) assess usability of, and satisfaction with, ImpulsePal. METHODS We conducted an individually randomized parallel two-arm nonblinded feasibility trial. The eligibility criteria included being aged ≥16 years, having a body mass index of ≥25 kg/m2, and having access to an Android-based device. Weight was measured (as the proposed primary outcome for a full-scale trial) at baseline, 1 month, and 3 months of follow-up. Participants were randomized in a 2:1 allocation ratio to the ImpulsePal intervention or a waiting list control group. A nested action-research study allowed for data-driven refinement of the intervention across 2 cycles of feedback. RESULTS We screened 179 participants for eligibility, and 58 were randomized to the intervention group and 30 to the control group. Data were available for 74 (84%, 74/88) participants at 1 month and 67 (76%, 67/88) participants at 3 months. The intervention group (n=43) lost 1.03 kg (95% CI 0.33 to 1.74) more than controls (n=26) at 1 month and 1.01 kg (95% CI −0.45 to 2.47) more than controls (n=43 and n=24, respectively) at 3 months. Feedback suggested changes to intervention design were required to (1) improve receipt and understanding of instructions and (2) facilitate further engagement with the app and its strategies. CONCLUSIONS The evaluation methods and delivery of the ImpulsePal app intervention are feasible, and the trial procedures, measures, and intervention are acceptable and satisfactory to the participants.

BACKGROUND The prevalence of gestational diabetes mellitus (GDM) is increasing worldwide. A healthy diet and stable blood glucose levels during pregnancy can prevent adverse health outcomes for the mother and the newborn child. Mobile health may be a useful supplement to prenatal care, providing women with targeted dietary information concerning GDM. OBJECTIVE We analyzed secondary data from a two-arm, multicentered, nonblinded randomized controlled trial to determine if a smartphone app with targeted dietary information and blood glucose monitoring had an effect on the dietary behavior of women with GDM. METHODS Women with a 2-hour oral glucose tolerance test level of ≥9 mmol/L were individually randomized to either the intervention group receiving the Pregnant+ app and usual care or the control group receiving usual care only. Eligible women were enrolled from 5 diabetes outpatient clinics in the Oslo region, Norway, between October 2015 and April 2017. The Pregnant+ app promoted 10 GDM-specific dietary recommendations. A healthy dietary score for Pregnant+ (HDS-P+) was constructed from a 41-item food frequency questionnaire and used to assess the intervention effect on the dietary behavior completed at trial entry and at around gestation week 36. Dietary changes from baseline to week 36 were examined by a paired sample two-tailed <i>t</i> test. Between-group dietary differences after the intervention were estimated with analysis of covariance, with adjustment for baseline diet. RESULTS A total of 238 women participated: 115 were allocated to the intervention group and 123 to the control group. Of the 238 women, 193 (81.1%) completed the food frequency questionnaire both at baseline and around gestational week 36. All the participants showed improvements in their HDS-P+ from baseline. However, the Pregnant+ app did not have a significant effect on their HDS-P+. The control group reported a higher weekly frequency of choosing fish meals (<i>P</i>=.05). No other significant differences were found between the intervention and control groups. There were no significant demographic baseline differences between the groups, except that more women in the intervention group had a non-Norwegian language as their first language (61 vs 46; <i>P</i>=.02). CONCLUSIONS Our findings do not support the supplementation of face-to-face follow-up of women with GDM with a smartphone app in the presence of high-standard usual care, as the Pregnant+ app did not have a beneficial effect on pregnant women’s diet.

Abstract Background There is evidence that depression can be prevented; however, traditional approaches face significant scalability issues. Digital technologies provide a potential solution, although this has not been adequately tested. The aim of this study was to evaluate the effectiveness of a new smartphone app designed to reduce depression symptoms and subsequent incident depression amongst a large group of Australian workers. Methods A randomized controlled trial was conducted with follow-up assessments at 5 weeks and 3 and 12 months post-baseline. Participants were employed Australians reporting no clinically significant depression. The intervention group (N = 1128) was allocated to use HeadGear, a smartphone app which included a 30-day behavioural activation and mindfulness intervention. The attention-control group (N = 1143) used an app which included a 30-day mood monitoring component. The primary outcome was the level of depressive symptomatology (PHQ-9) at 3-month follow-up. Analyses were conducted within an intention-to-treat framework using mixed modelling. Results Those assigned to the HeadGear arm had fewer depressive symptoms over the course of the trial compared to those assigned to the control (F3,734.7 = 2.98, p = 0.031). Prevalence of depression over the 12-month period was 8.0% and 3.5% for controls and HeadGear recipients, respectively, with odds of depression caseness amongst the intervention group of 0.43 (p = 0.001, 95% CI 0.26–0.70). Conclusions This trial demonstrates that a smartphone app can reduce depression symptoms and potentially prevent incident depression caseness and such interventions may have a role in improving working population mental health. Some caution in interpretation is needed regarding the clinical significance due to small effect size and trial attrition.

BACKGROUND Growing numbers of people use medication for chronic conditions; non-adherence is common, leading to poor disease control. A newly developed web-based tool to identify an increased risk for non-adherence with related potential individual barriers might facilitate tailored interventions and improve adherence. OBJECTIVE To assess the effectiveness of the newly developed tool to improve medication adherence. METHODS A cluster randomized controlled trial assessed the effectiveness of this adherence tool in patients initiating cardiovascular or oral blood glucose lowering medication. Participants were included in community pharmacies. They completed an online questionnaire comprising an assessments of their risk for medication non-adherence and subsequently of barriers to adherence. In pharmacies belonging to the intervention group, individual barriers displayed in a graphical profile on a tablet were discussed by pharmacists and patients at high non-adherence risk in face to face meetings and shared with their general practitioners and practice nurses. Tailored interventions were initiated by the healthcare providers. Barriers of control patients were not presented or discussed and these patients received usual care. The primary outcome was the difference in medication adherence at 8 months follow-up between patients with an increased non-adherence risk from intervention and control group, calculated from dispensing data. RESULTS Data from 492 participants in 15 community pharmacies were available for analyses (intervention 253, 7 pharmacies; control 239, 8 pharmacies). The intervention had no effect on medication adherence (-0.01; 95%CI -0.59 – 0.57; P= .96), neither in the post hoc per protocol analysis (0.19; 95%CI -0.50 – 0.89; P=.58). CONCLUSIONS This study showed no effectiveness of a risk stratification and tailored intervention addressing personal barriers for medication adherence. Various potential explanations for lack of effect were identified. These explanations relate for instance to high medication adherence in the control group, study power and fidelity. Process evaluation should elicit possible improvements and inform the redesign of intervention and implementation. CLINICALTRIAL The Netherlands National Trial Register: NTR5186.

Background and aim: Hypotension during cesarean section (CS) under spinal anesthesia has been a subject of scientific study for more than 50 years and the search for the most effective strategy to achieve hemodynamic stability remains challenging. Aim: The study was carried out to apply leg wrapping technique for the prevention of spinal-induced hypotension (SIH) during CS.Methods: Randomized Controlled Trial design was utilized at cesarean delivery operating room Mansoura General Hospital in El-Mansoura City during the period from May 2018 to November 2018. A purposive sample of 88 pregnant women, assigned randomly to an intervention group (n = 44) in which their legs wrapped with elastic crepe bandage and control group (n = 44) in which no wrapping was done. Data collected for maternal, neonatal hemodynamic and signs of hypotension, the feasibility of application and cost analysis.Results: There was a statistically significant difference in the incidence of SIH and Ephedrine use among both groups (18.20% in leg wrapping group whereas 75% in control group). In addition, neonatal acidosis and NICU admission were less among leg wrapping group (11.40%, 9.10% respectively). Economically, leg wrapping technique was cost effective compared to the cost of the hospital regimen for treating SIH and admission to (NICU).Conclusion and recommendations: Leg wrapping technique was cost effective and an efficient method for decreasing SIH, neonatal acidosis and Ephedrine administration. It is recommended to apply leg wrapping technique in maternal hospitals' protocol of care for decreasing SIH during CS.

Objective To evaluate the effectiveness of cognitive training in improving tinnitus bother and to identify predictors of patient response. Study Design Prospective open-label randomized controlled trial. Setting Online. Methods Participants were adults with subjective idiopathic nonpulsatile tinnitus causing significant tinnitus-related distress. The intervention group trained by using auditory-intensive exercises for 20 minutes per day, 5 days per week, for 8 weeks. The active control group trained on the same schedule with non–auditory intensive games. Surveys were completed at baseline, 8 weeks, and 12 weeks. Results A total of 64 participants completed the study. The median age was 63 years (range, 25-69) in the intervention group and 61 years (34-68) in the control group. Mixed model analysis revealed that within-subject change in Tinnitus Functional Index in the intervention group was not different than the control group, with marginal mean differences (95% CI): 0.24 (–11.20 to 10.7) and 2.17 (–8.50 to 12.83) at 8 weeks and 2.33 (–8.6 to 13.3) and 3.36 (–7.91 to 14.6) at 12 weeks, respectively. When the 2 study groups were compared, the control group had higher Tinnitus Functional Index scores than the intervention group by 10.5 points at baseline (95% CI, –0.92 to 29.89), 8.1 at 8 weeks (95% CI, –3.27 to 19.42), and 9.4 at 12 weeks (95% CI, –2.45 to 21.34). Conclusion Auditory-intensive cognitive training was not associated with changes in self-reported tinnitus bother. Given the potential for neuroplasticity to affect tinnitus, we believe that future studies on cognitive training for tinnitus remain relevant.

Background: During the COVID-19 pandemic, many primary care professionals were overburdened and experienced difficulties reaching vulnerable patients and meeting the increased need for psychosocial support. This randomized controlled trial (RCT) tested whether a primary healthcare (PHC) based community health worker (CHW) intervention could tackle psychosocial suffering due to physical distancing measures in patients with limited social networks. Methods: CHWs provided 8 weeks of tailored psychosocial support to the intervention group. Control group patients received ‘care as usual’. The impact on feelings of emotional support, social isolation, social participation, anxiety and fear of COVID-19 were measured longitudinally using a face-to-face survey to determine their mean change from baseline. Self-rated change in psychosocial health at 8 weeks was determined. Results: We failed to find a significant effect of the intervention on the prespecified psychosocial health measures. However, the intervention did lead to significant improvement in self-rated change in psychosocial health. Conclusions: This study confirms partially the existing evidence on the effectiveness of CHW interventions as a strategy to address mental health in PHC in a COVID context. Further research is needed to elaborate the implementation of CHWs in PHC to reach vulnerable populations during and after health crises.

Abstract Background Although almost a year has passed since the Coronavirus disease 2019 (COVID-19) outbreak and promising reports of vaccines have been presented, we still have a long way until these measures are available for all. Furthermore, the most appropriate corticosteroid and dose in the treatment of COVID-19 have remained uncertain. We conducted a study to assess the effectiveness of methylprednisolone treatment versus dexamethasone for hospitalized COVID-19 patients. Methods In this prospective triple-blinded randomized controlled trial, we enrolled 86 hospitalized COVID-19 patients from August to November 2020, in Shiraz, Iran. The patients were randomly allocated into two groups to receive either methylprednisolone (2 mg/kg/day; intervention group) or dexamethasone (6 mg/kg/day; control group). Data were assessed based on a 9-point WHO ordinal scale extending from uninfected (point 0) to death (point 8). Results There were no significant differences between the groups on admission. However, the intervention group demonstrated significantly better clinical status compared to the control group at day 5 (4.02 vs. 5.21, p = 0.002) and day 10 (2.90 vs. 4.71, p = 0.001) of admission. There was also a significant difference in the overall mean score between the intervention group and the control group, (3.909 vs. 4.873 respectively, p = 0.004). The mean length of hospital stay was 7.43 ± 3.64 and 10.52 ± 5.47 days in the intervention and control groups, respectively (p = 0.015). The need for a ventilator was significantly lower in the intervention group than in the control group (18.2% vs 38.1% p = 0.040). Conclusion In hospitalized hypoxic COVID-19 patients, methylprednisolone demonstrated better results compared to dexamethasone. Trial registration The trial was registered with IRCT.IR (08/04/2020-No. IRCT20200204046369N1).

Abstract Background Before the COVID-19 pandemic occurred in January 2020, the number of overseas visitors to Japan had increased threefold over the last decade. To minimize the risk of health problems, visitors should be able to access information on the health care systems of the places they visit. Most short-term overseas visitors are young adults. Although they are not very likely to get sick from noncommunicable diseases, they are at high risk for injury and often experience stomach ailments, fever, or nausea when travelling. The objective of this study is to evaluate culturally and linguistically appropriate health information on preventive health behaviours and the health care system in Japan. We will examine the level of satisfaction of overseas visitors to Japan with health care-related educational materials using a five-minute digital game named Sa-Chan Japan. Methods Our study is a randomized controlled trial (RCT). We will assess both satisfaction and motivation before, during, and after the interventions and examine the changes over time. The intervention group will comprise overseas visitors who will view and answer questions in an animation named Sa-Chan Japan. The control group will comprise overseas visitors who will watch an English digital animation named Mari Info Japan. We will recruit 1002 participants through the Macromill Internet portal. We will contact overseas visitors who have either visited or wish to visit Japan from the United Kingdom, United States, and Australia. The participants will fill out a self-administered questionnaire online in the first quarter of 2021. We will determine the participants’ levels of satisfaction with the CSQ-8 (8-item Client Satisfaction Questionnaire). We will analyse the median score of the overseas visitors with both the Wilcoxon rank-sum and the Wilcoxon signed-rank tests. Our protocol of randomized controlled trials follows the SPIRIT guidelines. Discussion Our research will utilize unique digital education strategies in a game that promotes health and safety among overseas visitors to Japan. We believe the results of this study will be useful in overcoming the current challenges regarding pretravel health requirements for overseas visitors worldwide. Trial registration Version 1 of this trial was registered in the UMIN-CTR (University Hospital Medical Information Network Center Clinical Trials Registry), and the trial registration data are available on UMIN000042483, November 17, 2020.

In order to understand if a physician prescribed medical information changes, the number of hospital readmission, and death among the heart failure patients. A 12-month randomized controlled trial was conducted (December 2013–2014). Totally, 120 patients were randomly allocated into two groups of intervention ( n = 60) and control ( n = 60). Accordingly, the control group was given the routine oral information by the nurse or physician, and the intervention group received the Information Prescription (IP) prescribed by the physician as well as the routine oral information. The data was collected via telephone interviews with the follow-up intervals of 6 and 12 months, and also for 1 year after the discharge. The patients with the median age of (IQR) 69.5 years old (19.8) death upon adjusting a Cox survival model, [RR = 0.67, 95%CI: 0.46–0.97]. Few patients died during 1 year in the intervention group compared to the controls (7 vs 15) [RR = 0.47, 95%CI: 0.20–1.06]. During a period of 6-month follow-up there was not statistically significant on death and readmission between two groups. Physician prescribed information was clinically and statistically effective on the reduction of death and hospital readmission rates among the HF patients in long term follow-up.
