Background Chronic fatigue syndrome (CFS) or myalgic encephalomyelitis (ME) is relatively common in children with limited evidence for treatment. The Phil Parker Lightning Process (LP) is a trademarked intervention, which >250 children use annually. There are no reported studies investigating the effectiveness or possible side effects of LP. Methods The trial population was drawn from the Bath and Bristol NHS specialist paediatric CFS or ME service. The study was designed as a pilot randomized trial with children (aged 12 to 18 years) comparing specialist medical care with specialist medical care plus the Lightning Process. Integrated qualitative methodology was used to explore the feasibility and acceptability of the recruitment, randomization and interventions. Results A total of 56 children were recruited from 156 eligible children (1 October 2010 to 16 June 2012). Recruitment, randomization and both interventions were feasible and acceptable. Participants suggested changes to improve feasibility and acceptability and we incorporated the following in the trial protocol: stopped collecting 6-week outcomes; introduced a second reminder letter; used phone calls to collect primary outcomes from nonresponders; informed participants about different approaches of each intervention and changed our recommendation for the primary outcome for the full study from school attendance to disability (SF-36 physical function subscale) and fatigue (Chalder Fatigue Scale). Conclusions Conducting randomized controlled trials (RCTs) to investigate an alternative treatment such as LP is feasible and acceptable for children with CFS or ME. Feasibility studies that incorporate qualitative methodology enable changes to be made to trial protocols to improve acceptability to participants. This is likely to improve recruitment rate and trial retention. Trial registration Feasibility study first randomization: 29 September 2010. Trial registration: Current Controlled Trials ISRCTN81456207 (31 July 2012). Full trial first randomization: 19 September 2012. PMID:24304689

The Beta-blocker to LOwer CArdiovascular Dialysis Events (BLOCADE) Feasibility Study aims to determine the feasibility of a large-scale randomized controlled trial with clinical endpoints comparing the beta-blocking agent carvedilol with placebo in patients receiving dialysis. The BLOCADE Feasibility Study is a randomized, double-blind, placebo-controlled, parallel group feasibility study comparing the beta-blocking agent carvedilol with placebo. Patients receiving dialysis for ≥3 months and who are aged ≥50 years, or who are ≥18 years and have diabetes or cardiovascular disease, were eligible. The primary outcome was the proportion of participants who complete a 6-week run-in phase in which all participants received carvedilol titrated from 3.125 mg twice daily to 6.25 mg twice daily. Other measures included how many patients are screened, the proportion recruited, the overall recruitment rate, the proportion of participants who remain on study drug for 12 months and the incidence of intra-dialytic hypotension while on randomized treatment. The BLOCADE Feasibility Study commenced recruiting in May 2011 and involves 11 sites in Australia and New Zealand. The BLOCADE Feasibility Study will inform the design of a larger clinical endpoint study to determine whether beta-blocking agents provide benefit to patients receiving dialysis, and define whether such a study is feasible. © 2014 Asian Pacific Society of Nephrology.

Hernia formation occurs at closed stoma sites in up to 30% of patients. The Reinforcement of Closure of Stoma Site (ROCSS) randomized controlled trial is evaluating whether placement of biological mesh during stoma closure safely reduces hernia rates compared with closure without mesh, without increasing surgical or wound complications. This paper aims to report recruitment, deliverability and safety from the internal feasibility study. A multicentre, patient and assessor blinded, randomized controlled trial, delivered through surgical trainee research networks. A 90-patient internal feasibility study assessed recruitment, randomization, deliverability and early (30 day) safety of the novel surgical technique (ClinicalTrials.gov registration number NCT02238964). The feasibility study recruited 90 patients from the 104 considered for entry (45 to mesh, 45 to no mesh). Seven of eight participating centres randomized patients within 30 days of opening. Overall, 41% of stomas were created for malignant disease and 73% were ileostomies. No mesh-specific complications occurred. Thirty-one postoperative adverse events were experienced by 31 patients, including surgical site infection (9%) and postoperative ileus (6%). One mesh was removed for re-access to the abdominal cavity, for reasons unrelated to the mesh. Independent review by the Data Monitoring and Ethics Committee of adverse event data by treatment allocation found no safety concerns. Multicentre randomization to this trial of biological mesh is feasible, with no early safety concerns. Progression to the full Phase III trial has continued. ROCSS shows that trainee research networks can efficiently develop and deliver complex interventional surgical trials.

Study Design Feasibility randomized clinical trial. Background Rehabilitation may be an appropriate treatment strategy for patients with chronic hip joint pain; however, the evidence related to the effectiveness of rehabilitation is limited. Objectives To assess feasibility of performing a randomized clinical trial to investigate the effectiveness of movement-pattern training (MPT) to improve function in people with chronic hip joint pain. Methods Thirty-five patients with chronic hip joint pain were randomized into a treatment (MPT) group or a control (wait-list) group. The MPT program included 6 one-hour supervised sessions and incorporated (1) task-specific training for basic functional tasks and symptom-provoking tasks, and (2) strengthening of hip musculature. The wait-list group received no treatment. Primary outcomes for feasibility were patient retention and adherence. Secondary outcomes to assess treatment effects were patient-reported function (Hip disability and Osteoarthritis Outcome Score), lower extremity kinematics, and hip muscle strength. Results Retention rates did not differ between the MPT (89%) and wait-list groups (94%, P = 1.0). Sixteen of the 18 patients (89%) in the MPT group attended at least 80% of the treatment sessions. For the home exercise program, 89% of patients reported performing their home program at least once per day. Secondary outcomes support the rationale for conduct of a superiority randomized clinical trial. Conclusion Based on retention and adherence rates, a larger randomized clinical trial appears feasible and warranted to assess treatment effects more precisely. Data from this feasibility study will inform our future clinical trial. Level of Evidence Therapy, level 2b-. J Orthop Sports Phys Ther 2016;46(6):452-461.

Objective Assess feasibility of randomizing women to intrauterine device (IUD) type. Study Design Women enrolling in a 2-month study who desired an IUD for contraception were randomized 1:1 to receive a levonorgestrel 52mg IUD (LNG-IUD) or copper T380A (Cu-IUD), understanding they could switch IUD type at the end of the study. Results Randomization to IUD type was acceptable to 54/55 (98%) women who screened. All 32 enrolled participants completed follow-up. Two women exchanged their IUD (Cu-IUD to LNG-IUD) and 2 requested removal (1 LNG-IUD, 1 Cu-IUD). Overall, 88% continued their assigned IUD. Conclusions Randomization to IUD type is feasible and few women change their IUD. PMID:26297203

The feasibility and stability of large complex biological networks: a random matrix approach.
Stone, Lewi
2018-05-29
In the 70's, Robert May demonstrated that complexity creates instability in generic models of ecological networks having random interaction matrices A. Similar random matrix models have since been applied in many disciplines. Central to assessing stability is the "circular law" since it describes the eigenvalue distribution for an important class of random matrices A. However, despite widespread adoption, the "circular law" does not apply for ecological systems in which density-dependence operates (i.e., where a species growth is determined by its density). Instead one needs to study the far more complicated eigenvalue distribution of the community matrix S = DA, where D is a diagonal matrix of population equilibrium values. Here we obtain this eigenvalue distribution. We show that if the random matrix A is locally stable, the community matrix S = DA will also be locally stable, providing the system is feasible (i.e., all species have positive equilibria D > 0). This helps explain why, unusually, nearly all feasible systems studied here are locally stable. Large complex systems may thus be even more fragile than May predicted, given the difficulty of assembling a feasible system. It was also found that the degree of stability, or resilience of a system, depended on the minimum equilibrium population.

To evaluate the feasibility of conducting a randomized controlled trial comparing group-based outpatient physiotherapy with usual care in patients following total knee replacement. A feasibility study for a randomized controlled trial. One secondary-care hospital orthopaedic centre, Bristol, UK. A total of 46 participants undergoing primary total knee replacement. The intervention group were offered six group-based exercise sessions after surgery. The usual care group received standard postoperative care. Participants were not blinded to group allocation. Feasibility was assessed by recruitment, reasons for non-participation, attendance, and completion rates of study questionnaires that included the Lower Extremity Functional Scale and Knee Injury and Osteoarthritis Outcome Score. Recruitment rate was 37%. Five patients withdrew or were no longer eligible to participate. Intervention attendance was high (73%) and 84% of group participants reported they were 'very satisfied' with the exercises. Return of study questionnaires at six months was lower in the usual care (75%) than in the intervention group (100%). Mean (standard deviation) Lower Extremity Functional Scale scores at six months were 45.0 (20.8) in the usual care and 57.8 (15.2) in the intervention groups. Recruitment and retention of participants in this feasibility study was good. Group-based physiotherapy was acceptable to participants. Questionnaire return rates were lower in the usual care group, but might be enhanced by telephone follow-up. The Lower Extremity Functional Scale had high responsiveness and completion rates. Using this outcome measure, 256 participants would be required in a full-scale randomized controlled trial.

One-third of North American adults with congenital heart disease (CHD) have diagnosable mood or anxiety disorders and most do not receive mental health treatment. There are no published interventions targeting the psychosocial needs of patients with CHD of any age. We describe the development of a group psychosocial intervention aimed at improving the psychosocial functioning, quality of life, and resilience of adults with CHD and the design of a study protocol to determine the feasibility of a potential full-scale randomized controlled trial (RCT). Drawing upon our quantitative and qualitative research, we developed the Adult CHD-Coping And REsilience (ACHD-CARE) intervention and designed a feasibility study that included a 2-parallel arm non-blinded pilot RCT. Eligible participants (CHD, age ≥ 18 years, no planned surgery, symptoms suggestive of a mood and/or anxiety disorder) were randomized to the ACHD-CARE intervention or Usual Care (1:1 allocation ratio). The group intervention was delivered during eight 90-minute weekly sessions. Feasibility will be assessed in the following domains: (i) process (e.g. recruitment and retention), (ii) resources, (iii) management, (iv) scientific outcomes, and (v) intervention acceptability. This study underscores the importance of carefully developing and testing the feasibility of psychosocial interventions in medical populations before moving to full-scale clinical trials. At study conclusion, we will be poised to make one of three determinations for a full-scale RCT: (1) feasible, (2) feasible with modifications, or (3) not feasible. This study will guide the future evaluation and provision of psychosocial treatment for adults with CHD. Copyright © 2015. Published by Elsevier Inc.

Objectives To determine the feasibility of conducting a randomized clinical trial designed to compare two methods of manual therapy (myofascial physical therapy (MPT) and global therapeutic massage (GTM)) among patients with urologic chronic pelvic pain syndromes. Materials and Methods Our goal was to recruit 48 subjects with chronic prostatitis/chronic pelvic pain syndrome or interstitial cystitis/painful bladder syndrome at six clinical centers. Eligible patients were randomized to either MPT or GTM and were scheduled to receive up to 10 weekly treatments, each 1 hour in duration. Criteria to assess feasibility included adherence of therapists to prescribed therapeutic protocol as determined by records of treatment, adverse events which occurred during study treatment, and rate of response to therapy as assessed by the Patient Global Response Assessment (GRA). Primary outcome analysis compared response rates between treatment arms using Mantel-Haenszel methods. Results Twenty-three (49%) men and 24 (51%) women were randomized over a six month period. Twenty-four (51%) patients were randomized to GTM, 23 (49%) to MPT; 44 (94%) patients completed the study. Therapist adherence to the treatment protocols was excellent. The GRA response rate of 57% in the MPT group was significantly higher than the rate of 21% in the GTM treatment group (p=0.03). Conclusions The goals to judge feasibility of conducting a full-scale trial of physical therapy methods were met. The preliminary findings of a beneficial effect of MPT warrants further study.

Epilepsy is the most common neurological problem that affects people with learning disabilities. The high seizure frequency, resistance to treatments, associated skills deficit and co-morbidities make the management of epilepsy particularly challenging for people with learning disabilities. The Books Beyond Words booklet for epilepsy uses images to help people with learning disabilities manage their condition and improve quality of life. Our aim is to conduct a randomized controlled feasibility trial exploring key methodological, design and acceptability issues, in order to subsequently undertake a large-scale randomized controlled trial of the Books Beyond Words booklet for epilepsy. We will use a two-arm, single-centre randomized controlled feasibility design, over a 20-month period, across five epilepsy clinics in Hertfordshire, United Kingdom. We will recruit 40 eligible adults with learning disabilities and a confirmed diagnosis of epilepsy and will randomize them to use either the Books Beyond Words booklet plus usual care (intervention group) or to receive routine information and services (control group). We will collect quantitative data about the number of eligible participants, number of recruited participants, demographic data, discontinuation rates, variability of the primary outcome measure (quality of life: Epilepsy and Learning Disabilities Quality of Life scale), seizure severity, seizure control, intervention's patterns of use, use of other epilepsy-related information, resource use and the EQ-5D-5L health questionnaire. We will also gather qualitative data about the feasibility and acceptability of the study procedures and the Books Beyond Words booklet. Ethical approval for this study was granted on 28 April 2014, by the Wales Research Ethics Committee 5. Recruitment began on 1 July 2014. The outcomes of this feasibility study will be used to inform the design and methodology of a definitive study, adequately powered to determine the impact of the Books Beyond Words intervention to improve the management of epilepsy in people with learning disabilities. http://ISRCTN80067039 (Date of ISRCTN assignation: 23 April 2014).

To assess the feasibility of conducting a randomized controlled trial of an instructional and educational stroke DVD and determine the feasibility and preliminary efficacy of this intervention in a multinational context. Non-funded, pilot randomized controlled trial of intervention versus usual care. International, multicentre, community-based. Community-living adults up to three years post stroke with moderate to severe disability and their nominated informal caregivers. Intervention patients viewed and practised rehabilitation techniques demonstrated in the DVD over six weeks. Trial feasibility by number of active recruitment sites, recruitment efficiency, randomization and follow-up. Intervention feasibility by patient and caregiver impressions. Preliminary efficacy by the quality of life - 5-level EuroQol-5D (EQ-5D) health status measure, General Health Questionnaire and Centre for Epidemiological Studies-Depression at two months. In total, 14 recruitment sites were established across eight countries. Recruitment was achieved at nine (64%) sites. Over 16 months, 66 participants were recruited (mean (SD) age = 63.5 (12.47) years) and randomized to intervention ( n = 34) and control ( n = 32) groups. In total, 54 (82%) completed a follow-up assessment. Patient and/or caregiver comments about the benefits and barriers to accessing the intervention were mixed. There were no significant between-group differences in outcomes at two months ( P > 0.05). Conducting a multinational trial of a stroke DVD requires full funding. The intervention was acceptable to some patients and their caregivers, yet a generalized education approach did not fully meet their needs and/or expectations. A more individualized method may be required to meet peoples' changing needs during stroke recovery.

This report aims to assess the safety and feasibility of using an interdisciplinary rehabilitation intervention for a future randomized controlled trial in patients with gliomas in the initial treatment phase. We conducted an outpatient two-part rehabilitation intervention that involved six weeks of therapeutic supervised training (part one) and six weeks of unsupervised training in a local gym following a training protocol (part two). Predefined feasibility objectives of safety (100%), consent rate (>80%), drop-out (<20%), adherence (>80%) and patient satisfaction (>80%) was achieved at part one. However, the failure to meet predefined feasibility objectives of drop-out, adherence and patient satisfaction of the unsupervised intervention at part two have led to a protocol revision for a future randomized controlled trial. This study demonstrates that an intensive rehabilitation intervention of physical therapy and occupational therapy in the initial treatment phase of patients with gliomas whose Karnofsky performance status is ≥70 is safe and feasible, if relevant inclusion criteria and precautionary screening are made. With the revised protocol, we are confident that the foundation for conducting a successful randomized controlled trial among these vulnerable patients has been established. Implications for rehabilitation Brain tumors constitute some of the most challenging cancer diagnoses presenting for rehabilitation intervention. Patients with gliomas experiences limitations in physical functioning, cognition, and emotional wellbeing. In a relatively small sample this study shows that supervised physical- and occupational therapy in patients with gliomas is safe and feasible in the initial treatment phase. Patients with gliomas can potentially improve functioning through interdisciplinary rehabilitation.

We developed the Hemodialysis Infection Prevention Protocols Ontario-Shower Technique (HIPPO-ST) to permit hemodialysis (HD) patients with central venous catheters (catheters) to shower without additional infection risk. Our primary objective was to determine the feasibility of conducting a parallel randomized controlled trial (RCT) to evaluate the impact of HIPPO-ST on catheter-related bacteremia (CRB) in adult HD patients. Adult HD patients using catheters were recruited from 11 HD units. Patients were randomized to receive HIPPO-ST or standard care and were followed up for 6 months. Only CRB-outcome assessors were blinded. For the study to be considered feasible, 4 of 5 feasibility outcomes, each with its own statistical threshold for success, must have been achieved. A total of 68 patients were randomized (33 HIPPO-ST and 35 control) and were followed up to 6 months. Of 5 measures of feasibility, 4 were achieved: (1) accurate CRB rate documented (threshold: κ level >0.80); (2) 97.8% (279/285) of satellite HD patients with catheters were screened (threshold: >95%); (3) 88% (23/26) in the HIPPO-ST arm were successfully educated by 6 months (threshold: >80%); and (4) 0% (0/29) patients in the control arm were "contaminated," that is, using HIPPO-ST (threshold: <5%). However, only 44.2% (72/163) of eligible patients consented to participate (threshold: >80%). The rate of CRB was similarly low in HIPPO-ST and control groups (0.68 vs. 0.88/1000 catheter days). This HIPPO-ST pilot study demonstrated the feasibility of the larger HIPPO-ST study, especially given the high levels of education success with the HIPPO-ST arm and the low levels of contamination in the control arm.

To establish the feasibility and effectiveness of a six week ballistic strength training protocol in people with stroke. Randomized, controlled, assessor-blinded study. Sub-acute inpatient rehabilitation. Consecutively admitted inpatients with a primary diagnosis of first ever stroke with lower limb weakness, functional ambulation category score of ≥3, and ability to walk ≥14m were screened for eligibility to recruit 30 participants for randomization. Participants were randomized to standard therapy or ballistic strength training three times per week for six weeks. The primary aim was to evaluate feasibility and outcomes included recruitment rate, participant retention and attrition, feasibility of the exercise protocol, therapist burden and participant safety. Secondary outcomes included measures of mobility, lower limb muscle strength, muscle power and quality of life. Thirty participants (11% of those screened) with mean age of 50 (SD 18) years were randomized. The median number of sessions attended was 15/18 and 17/18 for the ballistic and control groups respectively. Earlier than expected discharge home (n=4) and illness (n=7) were the most common reasons for non-attendance. Participants performed the exercises safely, with no study-related adverse events. There were significant (p<0.05) between-group changes favoring the ballistic group for comfortable gait velocity (mean difference (MD) 0.31m/s, 95% confidence interval CI: 0.08 to 0.52), muscle power, as measured by peak jump height (MD 8cm, 95% CI: 3 to 13) and peak propulsive velocity (MD 64cm/s, 95% CI: 17 to 112). Ballistic training was safe and feasible in select ambulant people with stroke. Similar rates of retention and attrition suggest that ballistic training was acceptable to patients. Secondary outcomes provide promising results that warrant further investigation in a larger trial. Copyright © 2018. Published by Elsevier Inc.

Background Current Medical Research Council (MRC) guidance on complex interventions advocates pilot trials and feasibility studies as part of a phased approach to the development, testing, and evaluation of healthcare interventions. In this paper we discuss the results of a recent feasibility study and pilot trial for a randomized controlled trial (RCT) of pelvic floor muscle training for prolapse (ClinicalTrials.gov: NCT01136889). The ways in which researchers decide to respond to the results of feasibility work may have significant repercussions for both the nature and degree of tension between internal and external validity in a definitive trial. Methods We used methodological issues to classify and analyze the problems that arose in the feasibility study. Four centers participated with the aim of randomizing 50 women. Women were eligible if they had prolapse of any type, of stage I to IV, and had a pessary successfully fitted. Postal questionnaires were administered at baseline, 6 months, and 7 months post-randomization. After identifying problems arising within the pilot study we then sought to locate potential solutions that might minimize the trade-off between a subsequent explanatory versus pragmatic trial. Results The feasibility study pointed to significant potential problems in relation to participant recruitment, features of the intervention, acceptability of the intervention to participants, and outcome measurement. Finding minimal evidence to support our decision-making regarding the transition from feasibility work to a trial, we developed a systematic process (A process for Decision-making after Pilot and feasibility Trials (ADePT)) which we subsequently used as a guide. The process sought to: 1) encourage the systematic identification and appraisal of problems and potential solutions; 2) improve the transparency of decision-making processes; and 3) reveal the tensions that exist between pragmatic and explanatory choices. Conclusions We have developed a process that may aid researchers in their attempt to identify the most appropriate solutions to problems identified within future pilot and feasibility RCTs. The process includes three key steps: a decision about the type of problem, the identification of all solutions (whether addressed within the intervention, trial design or clinical context), and a systematic appraisal of these solutions.

To determine whether it was feasible to perform a randomized controlled trial (RCT) comparing arthroscopic hip surgery to conservative care in patients with femoroacetabular impingement (FAI). This study had two phases: a pre-pilot and pilot RCT. In the pre-pilot, we conducted interviews with clinicians who treated FAI and with FAI patients to determine their views about an RCT. We developed protocols for operative and conservative care. In the pilot RCT, we determined the rates of patient eligibility, recruitment and retention, to investigate the feasibility of the protocol and we established methods to assess treatment fidelity. In the pre-pilot phase, 32 clinicians were interviewed, of which 26 reported theoretical equipoise, but in example scenarios 7 failed to show clinical equipoise. Eighteen patients treated for FAI were also interviewed, the majority of whom felt that surgery and conservative care were acceptable treatments. Surgery was viewed by patients as a 'definitive solution'. Patients were motivated to participate in research but were uncomfortable about randomization. Randomization was more acceptable if the alternative was available at the end of the trial. In the pilot phase, 151 patients were assessed for eligibility. Sixty were eligible and invited to take part in the pilot RCT; 42 consented to randomization. Follow-up was 100% at 12 months. Assessments of treatment fidelity were satisfactory. An RCT to compare arthroscopic hip surgery with conservative care in patients with FAI is challenging but feasible. Recruitment has started for a full RCT.

To investigate the feasibility of a randomized controlled trial of a home-based balance intervention for people with cerebellar ataxia. A randomized controlled trial design. Intervention and assessment took place in the home environment. A total of 12 people with spinocerebellar ataxia type 6 were randomized into a therapy or control group. Both groups received identical assessments at baseline, four and eight weeks. Therapy group participants undertook balance exercises in front of optokinetic stimuli during weeks 4-8, while control group participants received no intervention. Test-retest reliability was analysed from outcome measures collected twice at baseline and four weeks later. Feasibility issues were evaluated using daily diaries and end trial exit interviews. The home-based training intervention with opto-kinetic stimuli was feasible for people with pure ataxia, with one drop-out. Test-retest reliability is strong (intraclass correlation coefficient >0.7) for selected outcome measures evaluating balance at impairment and activity levels. Some measures reveal trends towards improvement for those in the therapy group. Sample size estimations indicate that Bal-SARA scores could detect a clinically significant change of 0.8 points in this functional balance score if 80 people per group were analysed in future trials. Home-based targeted training of functional balance for people with pure cerebellar ataxia is feasible and the outcome measures employed are reliable. © The Author(s) 2014.

One of the most difficult symptoms for persons with sickle cell disease (SCD) to manage is chronic pain. Chronic pain impacts approximately one-third of persons with SCD and is associated with increased pain intensity, pain behavior, and frequency and duration of hospital visits. A promising category of nonpharmacological interventions for managing both physical and affective components of pain are mindfulness-based interventions (MBIs). The primary aim of this study is to conduct a randomized controlled study to evaluate the acceptability and feasibility, as well as to determine the preliminary efficacy, of a telephonic MBI for adults with SCD who have chronic pain. We will enroll 60 adult patients with SCD and chronic pain at an outpatient comprehensive SCD center in the southeastern United States. Patients will be randomized to either an MBI or a wait-listed control group. The MBI group will complete a six-session (60 minutes), telephonically delivered, group-based MBI program. The feasibility, acceptability, and efficacy of the MBI regarding pain catastrophizing will be assessed by administering questionnaires at baseline and weeks 1, 3, and 6. In addition, ten randomly selected MBI participants will complete semistructured interviews to help determine intervention acceptability. In this study protocol, we report detailed methods of the randomized controlled trial. Findings of this study will be useful to determine the acceptability, feasibility, and efficacy of an MBI for persons with SCD and chronic pain. ClinicalTrials.gov identifier: NCT02394587 .

Placement of prophylactic inferior vena cava filters (pIVCFs) for the prevention of pulmonary embolism (PE) in high-risk trauma patients (HRTPs) are widely practiced despite the lack of Level I data supporting this use. We report the 2-year interim analysis of the Filters in Trauma pilot study. This is a single institution, prospective randomized controlled pilot feasibility study in a Level I trauma center. HRTPs were identified for pIVCF placement by the Eastern Association for the Surgery of Trauma guidelines. From November 2008 to November 2010, HRTPs were enrolled and randomized to either pIVCF or no pIVCF. All patients received pharmacologic prophylaxis when safe. Primary outcomes included feasibility objectives and secondary outcomes were incidence of PE, deep vein thrombosis (DVT), and death. Thirty-four of 38 enrolled patients were eligible for analysis. The baseline sociodemographic characteristics were balanced between the both groups. Results of the feasibility objectives included: time from admission to enrollment (mean, 47.4 hours ± 22.0 hours), time from enrollment to randomization (mean, 4.8 hours ± 9.1 hours), time from randomization to IVCF placement (mean, 16.9 hours ± 9.2 hours), adherence to weekly compression ultrasound within first month (IVCF group = 44.4%; non-IVCF group = 62.5%), and 1-month clinical follow-up (IVCF group = 83.3%; non-IVCF group = 100%). At 6-month follow-up, one PE in the nonfilter group and one DVT in the filter group had occurred. One non-PE-related death occurred in the filter group. Barriers to enrollment included inability to obtain informed consent due to patient refusal or no next of kin identified and delayed notification of eligibility status. Our pilot study demonstrates for the first time that a randomized controlled trial evaluating the efficacy of pIVCFs in trauma patients is feasible. This pilot data will be used to inform the design of a multicenter randomized controlled trial to determine the incidence of PE and DVT in HRTPs receiving pIVCFs versus no pIVCF.

To date, only limited data exist about the use of xenon as an anaesthetic agent in patients undergoing cardiac surgery. The favourable cardio- and neuroprotective properties of xenon might attenuate postoperative complications, improve outcome, and reduce the incidence of delirium. Thus, the aims of this study were to investigate the feasibility and safety of balanced xenon anaesthesia in patients undergoing cardiac surgery and to gather pilot data for a future randomized multicentre study. Thirty patients undergoing elective coronary artery bypass grafting were enrolled in this randomized, single-blind controlled trial. They were randomized to receive balanced general anaesthesia with either xenon (45-50 vol%) or sevoflurane (1-1.4 vol%). The primary outcome was the occurrence of adverse events (AEs). Secondary outcome parameters were feasibility criteria (bispectral index, perioperative haemodynamic, and respiratory profile) and safety parameters (dosage of study treatments, renal function, intraoperative blood loss, need for inotropic support, regional cerebral tissue oxygenation). Furthermore, at predefined time points, systemic and pulmonary haemodynamics were assessed by the use of a pulmonary artery catheter. There were no patient characteristic differences between the groups. Patients undergoing xenon anaesthesia did not differ with respect to the incidence of AE (6 vs 8, P=0.464) compared with the sevoflurane group. No differences were detected regarding secondary feasibility and safety criteria. The haemodynamic and respiratory profile was comparable between the treatment groups. Balanced xenon anaesthesia is feasible and safe compared with sevoflurane anaesthesia in patients undergoing coronary artery bypass surgery.

Malignant bowel obstruction (MBO) is common in patients with advanced cancer. To perform a phase II study to assess the feasibility of conducting a phase III trial investigating the therapeutic value of gastrografin in MBO. Randomized double-blinded placebo-controlled feasibility study. Participants received 100 mL of either gastrografin or placebo. Over 8 months, 57 patients were screened and 9 enrolled (15.8% recruitment rate). Of the 9 enrolled, 4 received gastrografin (with 2 completing assessment) and 5 received placebo (with 4 completing assessment). It is not feasible to conduct a phase III trial using the same study protocol. This study validates the use of the phase II feasibility study to assess protocol viability in a palliative population prior to embarking on a larger trial.

Background Information on major harms of medical interventions comes primarily from epidemiologic studies performed after licensing and marketing. Comparison with data from large-scale randomized trials is occasionally feasible. We compared evidence from randomized trials with that from epidemiologic studies to determine whether they give different estimates of risk for important harms of medical interventions. Methods We targeted well-defined, specific harms of various medical interventions for which data were already available from large-scale randomized trials (> 4000 subjects). Nonrandomized studies involving at least 4000 subjects addressing these same harms were retrieved through a search of MEDLINE. We compared the relative risks and absolute risk differences for specific harms in the randomized and nonrandomized studies. Results Eligible nonrandomized studies were found for 15 harms for which data were available from randomized trials addressing the same harms. Comparisons of relative risks between the study types were feasible for 13 of the 15 topics, and of absolute risk differences for 8 topics. The estimated increase in relative risk differed more than 2-fold between the randomized and nonrandomized studies for 7 (54%) of the 13 topics; the estimated increase in absolute risk differed more than 2-fold for 5 (62%) of the 8 topics. There was no clear predilection for randomized or nonrandomized studies to estimate greater relative risks, but usually (75% [6/8]) the randomized trials estimated larger absolute excess risks of harm than the nonrandomized studies did. Interpretation Nonrandomized studies are often conservative in estimating absolute risks of harms. It would be useful to compare and scrutinize the evidence on harms obtained from both randomized and nonrandomized studies. PMID:16505459

Innovative strategies are needed to reduce the hypertension epidemic among African Americans. Reach Out was a faith-collaborative, mobile health, randomized, pilot intervention trial of four mobile health components to reduce high blood pressure (BP) compared to usual care. It was designed and tested within a community-based participatory research framework among African Americans recruited and randomized from churches in Flint, Michigan. The purpose of this pilot study was to assess the feasibility of the Reach Out processes. Feasibility was assessed by willingness to consent (acceptance of randomization), proportion of weeks participants texted their BP readings (intervention use), number lost to follow-up (retention), and responses to postintervention surveys and focus groups (acceptance of intervention). Of the 425 church members who underwent BP screening, 94 enrolled in the study and 73 (78%) completed the 6-month outcome assessment. Median age was 58 years, and 79% were women. Participants responded with their BPs on an average of 13.7 (SD = 10.7) weeks out of 26 weeks that the BP prompts were sent. All participants reported satisfaction with the intervention. Reach Out, a faith-collaborative, mobile health intervention was feasible. Further study of the efficacy of the intervention and additional mobile health strategies should be considered.

The purpose of this study was to determine the feasibility and acceptability of kangaroo care in a tertiary care hospital in India. A randomized controlled trial was performed over one year period in which 89 neonates were randomized into two groups kangaroo mother care (KMC) and conventional method of care (CMC). Forty-four babies were randomized into KMC group and 45 to CMC. There was significant reduction in KMC vs CMC group of hypothermia (10/44 vs 21/45, p-value < 0.01), higher oxygen saturations (95.7 vs 94.8%, p-value < 0.01) and decrease in respiratory rates (36.2 vs 40.7, p-value < 0.01). There were no statistically significant differences in the incidence of hyperthermia, sepsis, apnea, onset of breastfeeding and hospital stay in two groups. 79% of mothers felt comfortable during the KMC and 73% felt they would be able to give KMC at home. KMC is feasible, as mothers are already admitted in hospitals and are involved in the care of newborn. KMC is a simple and feasible intervention; acceptable to most mothers admitted in hospitals. There may be benefits in terms of reducing the incidence of hypothermia with no adverse effects of KMC demonstrated in the study. The present study has important implications in the care of LBW infants in the developing countries, where expensive facilities for conventional care may not be available at all place.

Red blood cell (RBC) transfusion thresholds have yet to be examined in large randomized trials in hematologic malignancies. This pilot study in acute leukemia uses a restrictive compared to a liberal transfusion strategy. A randomized (2:1) study was conducted of restrictive (LOW) hemoglobin (Hb) trigger (7 g/dL) compared to higher (HIGH) Hb trigger (8 g/dL). The primary outcome was feasibility of conducting a larger trial. The four requirements for success required that more than 50% of the eligible patients could be consented, more than 75% of the patients randomized to the LOW arm tolerated the transfusion trigger, fewer than 15% of patients crossed over from the LOW arm to the HIGH arm, and no indication for the need to pause the study for safety concerns. Secondary outcomes included fatigue, bleeding, and RBCs and platelets transfused. Ninety patients were consented and randomly assigned to LOW to HIGH. The four criteria for the primary objective of feasibility were met. When the number of units transfused was compared, adjusting for baseline Hb, the LOW arm was transfused on average 8.0 (95% confidence interval [CI], 6.9-9.1) units/patient while the HIGH arm received 11.7 (95% CI, 10.1-13.2) units (p = 0.0003). There was no significant difference in bleeding events or neutropenic fevers between study arms. This study establishes feasibility for trial of Hb thresholds in leukemia through demonstration of success in all primary outcome metrics and a favorable safety profile. This population requires further study to evaluate the equivalence of liberal and restrictive transfusion thresholds in this unique clinical setting. © 2016 AABB.

The Effectiveness of Discontinuing Bisphosphonates (EDGE) study is a planned pragmatic clinical trial to guide "drug holiday" clinical decision making. This pilot study assessed work flow and feasibility of such a study. While participant recruitment and treatment adherence were suboptimal, administrative procedures were generally feasible and minimally disrupted clinic flow. The comparative effectiveness of continuing or discontinuing long-term alendronate (ALN) on fractures is unknown. A large pragmatic ALN discontinuation study has potential to answer this question. We conducted a 6-month pilot study of the planned the EDGE study among current long-term ALN users (women aged ≥65 with ≥3 years of ALN use) to determine study work flow and feasibility including evaluating the administrative aspects of trial conduct (e.g., time to contract, institutional review board (IRB) approval), assessing rates of site and participant recruitment, and evaluating post-randomization outcomes, including adherence, bisphosphonate-associated adverse events, and participant and site satisfaction. We assessed outcomes 1 and 6 months after randomization. Nine sites participated, including seven community-based medical practices and two academic medical centers. On average (SD), contract execution took 3.4 (2.3) months and IRB approval took 13.9 (4.1) days. Sites recruited 27 participants (13 to continue ALN and 14 to discontinue ALN). Over follow-up, 22% of participants did not adhere to their randomization assignment: 30.8% in the continuation arm and 14.3% in the discontinuation arm. No fractures or adverse events were reported. Sites reported no issues regarding work flow, and participants were highly satisfied with the study. Administrative procedures of the EDGE study were generally feasible, with minimal disruption to clinic flow. In this convenience sample, participant recruitment was suboptimal across most practice sites. Accounting for low treatment arm adherence, a comprehensive recruitment approach will be needed to effectively achieve the scientific goals of the EDGE study.

Acceptance and Commitment Therapy (ACT) has growing support for chronic pain. However, more accessible treatment delivery is needed. This study evaluated the feasibility of online ACT for patients with complex chronic pain in the United Kingdom to determine whether a larger trial is justified. Participants with chronic pain and clinically meaningful disability and distress were randomly assigned to ACT online plus specialty medical pain management, or specialty medical management alone. Participants completed questionnaires at baseline, and 3- and 9-month post-randomization. Primary feasibility outcomes included recruitment, retention and treatment completion rates. Secondary outcomes were between-groups effects on treatment outcomes and psychological flexibility. Of 139 potential participants, 63 were eligible and randomized (45% recruitment rate). Retention rates were 76-78% for follow-up assessments. Sixty-one per cent of ACT online participants completed treatment. ACT online was less often completed by employed (44%) compared to unemployed (80%) participants. Fifty-six per cent of ACT online participants rated themselves as 'much improved' or better on a global impression of change rating, compared to only 20 per cent of control participants. Three-month effects favouring ACT online were small for functioning, medication and healthcare use, committed action and decentring, medium for mood, and large for acceptance. Small-to-medium effects were maintained for functioning, healthcare use and committed action at 9 months. Online ACT for patients with chronic pain in the United Kingdom appears feasible to study in a larger efficacy trial. Some adjustments to treatment and trial procedures are warranted, particularly to enhance engagement among employed participants. This study supports the feasibility of online Acceptance and Commitment Therapy for chronic pain in the United Kingdom and a larger efficacy trial. Refinements to treatment delivery, particularly to better engage employed patients, may improve treatment completion and outcomes. © 2018 European Pain Federation - EFIC®.

Group patient visits are medical appointments shared among patients with a common medical condition. This care delivery method has demonstrated benefits for individuals with chronic conditions but has not been evaluated for Parkinson disease (PD). We conducted a 12-month, randomized trial of group patient visits vs usual (one-on-one) care for patients with PD. Visits were led by one of 3 study physicians, included patients and caregivers, and lasted approximately 90 minutes. Those receiving group visits had 4 sessions over 12 months. The primary outcome measure was feasibility as measured by the ability to recruit participants and by the proportion of participants who completed the study. The primary efficacy outcome was quality of life as measured by the PD Questionnaire-39. Thirty patients and 27 caregivers enrolled in the study. Thirteen of the 15 patients randomized to group patient visits and 14 of the 15 randomized to usual care completed the study. Quality of life measured 12 months after baseline between the 2 groups was not different (25.9 points for group patient visits vs 26.0 points for usual care; p = 0.99). Group patient visits may be a feasible means of providing care to individuals with PD and may offer an alternative or complementary method of care delivery for some patients and physicians. This study provides Class II evidence that group patient visits did not improve quality of life for individuals with PD over a 1-year period.

Background There is a need for evidence of the clinical effectiveness of minimally invasive surgery for the treatment of esophageal cancer, but randomized controlled trials in surgery are often difficult to conduct. The ROMIO (Randomized Open or Minimally Invasive Oesophagectomy) study will establish the feasibility of a main trial which will examine the clinical and cost-effectiveness of minimally invasive and open surgical procedures for the treatment of esophageal cancer. Methods/Design A pilot randomized controlled trial (RCT), in two centers (University Hospitals Bristol NHS Foundation Trust and Plymouth Hospitals NHS Trust) will examine numbers of incident and eligible patients who consent to participate in the ROMIO study. Interventions will include esophagectomy by: (1) open gastric mobilization and right thoracotomy, (2) laparoscopic gastric mobilization and right thoracotomy, and (3) totally minimally invasive surgery (in the Bristol center only). The primary outcomes of the feasibility study will be measures of recruitment, successful development of methods to monitor quality of surgery and fidelity to a surgical protocol, and development of a core outcome set to evaluate esophageal cancer surgery. The study will test patient-reported outcomes measures to assess recovery, methods to blind participants, assessments of surgical morbidity, and methods to capture cost and resource use. ROMIO will integrate methods to monitor and improve recruitment using audio recordings of consultations between recruiting surgeons, nurses, and patients to provide feedback for recruiting staff. Discussion The ROMIO study aims to establish efficient methods to undertake a main trial of minimally invasive surgery versus open surgery for esophageal cancer. Trial registration The pilot trial has Current Controlled Trials registration number ISRCTN59036820(25/02/2013) at http://www.controlled-trials.com; the ROMIO trial record at that site gives a link to the original version of the study protocol.

The primary objective of this study was to assess feasibility and gather preliminary outcome data on Mindfulness-Based Resilience Training (MBRT) for law enforcement officers. Participants (n = 61) were randomized to either an 8-week MBRT course or a no intervention control group. Self-report and physiological data were collected at baseline, post-training, and three months following intervention completion. Attendance, adherence, post-training participant feedback, and interventionist fidelity to protocol all demonstrated feasibility of MBRT for law enforcement officers. Compared to no intervention controls, MBRT participants experienced greater reductions in salivary cortisol, self-reported aggression, organizational stress, burnout, sleep disturbance, and reported increases in psychological flexibility and non-reactivity at post-training; however, group differences were not maintained at three-month follow-up. This initial randomized trial suggests MBRT is a feasible intervention. Outcome data suggest MBRT targets key physiological, psychological, and health risk factors in law enforcement officers, consistent with the potential to improve officer health and public safety. However, follow-up training or "booster" sessions may be needed to maintain training gains. A fully powered longitudinal randomized trial is warranted. Copyright © 2018 Elsevier B.V.

Adolescents who self-harm are often unsure how or where to get help. We developed a Web-based personalized decision aid (DA) designed to support young people in decision making about seeking help for their self-harm. The aim of this study was to evaluate the feasibility and acceptability of the DA intervention and the randomized controlled trial (RCT) in a school setting. We conducted a two-group, single blind, randomized controlled feasibility trial in a school setting. Participants aged 12 to 18 years who reported self-harm in the past 12 months were randomized to either a Web-based DA or to general information about mood and feelings. Feasibility of recruitment, randomization, and follow-up rates were assessed, as was acceptability of the intervention and study procedures. Descriptive data were collected on outcome measures examining decision making and help-seeking behavior. Qualitative interviews were conducted with young people, parents or carers, and staff and subjected to thematic analysis to explore their views of the DA and study processes. Parental consent was a significant barrier to young people participating in the trial, with only 17.87% (208/1164) of parents or guardians who were contacted for consent responding to study invitations. Where parental consent was obtained, we were able to recruit 81.7% (170/208) of young people into the study. Of those young people screened, 13.5% (23/170) had self-harmed in the past year. Ten participants were randomized to receiving the DA, and 13 were randomized to the control group. Four-week follow-up assessments were completed with all participants. The DA had good acceptability, but qualitative interviews suggested that a DA that addressed broader mental health problems such as depression, anxiety, and self-harm may be more beneficial. A broad-based mental health DA addressing a wide range of psychosocial problems may be useful for young people. The requirement for parental consent is a key barrier to intervention research on self-harm in the school setting. Adaptations to the research design and the intervention are needed before generalizable research about DAs can be successfully conducted in a school setting.

Planning a well-designed research study can be tedious and laborious work. However, this process is critical and ultimately can produce valid, reliable study findings. Designing a large-scale randomized, controlled trial (RCT)-the gold standard in quantitative research-can be even more challenging. Even the most well-planned study potentially can result in issues with research procedures and design, such as recruitment, retention, or methodology. One strategy that may facilitate sound study design is the completion of a pilot or feasibility study prior to the initiation of a larger-scale trial. This article will discuss pilot and feasibility studies, their advantages and disadvantages, and implications for oncology nursing research. .

Osteoarthritis (OA) is a degenerative joint disease affecting the knee joint of many middle-aged and older adults. As OA symptoms typically involve knee pain and stiffness, individuals with knee OA are often insufficiently physically active, have low levels of physical function, and are at increased risk of other comorbidities and reduced quality of life. While moderate-intensity continuous training (MICT) cycling is often recommended, little is known about the feasibility, safety, and benefits of high-intensity interval training (HIIT) cycling for this population, even though the feasibility, safety, and benefits of HIIT have been demonstrated in other chronic disease groups. The primary objective of this pilot study was to examine the feasibility and safety of home-based HIIT and MICT cycling in middle-aged and older adults with knee OA. A secondary objective was to gain some insight into the relative efficacy of HIIT and MICT for improving health status (pain, stiffness, and disability), muscle function, and body composition in this population. This study protocol is being published separately to allow a detailed description of the research methods, explain the rationale for choosing the methodological details, and to stimulate consideration of the best means to simulate a research protocol that is relevant to a real-life treatment environment. Randomized pilot study protocol. This trial sought to recruit 40 middle-aged and older adults with knee OA. Participants were randomly allocated to either continuous (MICT) or HIIT home-based cycle training programs, with both programs requiring the performance of 4 cycling sessions (approximately 25 minutes per session) each week. Participants were measured at baseline and postintervention (8 weeks). Feasibility and safety were assessed by adherence rate, dropout rate, and number of adverse events. The relative efficacy of the cycling programs was investigated by 2 knee OA health status questionnaires (Western Ontario and McMaster Universities Osteoarthritis Index scale[WOMAC] and the Lequesne Index) as well as the timed up and go, sit to stand, preferred gait speed, and body composition. This pilot study appears to be the first study assessing the feasibility and safety of a home-based HIIT training program for middle-aged and older adults with knee OA. As HIIT has been demonstrated to be more effective than MICT for improving aspects of health status, body composition, and/or muscular function in other chronic disease groups, the current study has the potential to improve patient outcomes and inform the design of future randomized controlled trials.

Balance deficits following stroke are common and debilitating. Commercially available gaming systems, such as the Nintendo(®) (Kyoto, Japan) Wii™, have been widely adopted clinically; however, there is limited evidence supporting their feasibility and efficacy for improving balance performance following stroke. The aim of this trial is to investigate the clinical feasibility and efficacy of using the Nintendo Wii gaming system as an adjunct to standard care to improve balance performance following stroke in an inpatient rehabilitation setting. Thirty participants undergoing inpatient stroke rehabilitation will be recruited into this Phase II, single-blind, randomized controlled trial. Participants will be allocated into a Balance or Upper Limb Group, and both groups will perform activities using the Nintendo Wii in addition to their standard care. Participants will attend three 45-minute sessions per week, for a minimum of 2 and a maximum of 4 weeks. The main focus of the study is to investigate the feasibility of the intervention protocol. This will be evaluated through recruitment, retention, adherence, acceptability, and safety. The Step Test and Functional Reach Test will be the primary efficacy outcomes. Secondary outcomes will include force platform, mobility, and upper limb measures. Assessments will occur at baseline, 2 weeks, and 4 weeks after study entry. To the authors' knowledge, this will be the largest randomized clinical trial to investigate the feasibility and efficacy of the Nintendo Wii gaming system for improving balance performance in a stroke population. The results will inform the design of a Phase III multicenter trial.

Many older adults rely on a manual wheelchair for mobility but typically receive little, if any, training on how to use their wheelchair effectively and independently. Standardized skill training is an effective intervention, but limited access to clinician trainers is a substantive barrier. Enhancing Participation in the Community by Improving Wheelchair Skills (EPIC Wheels) is a 1-month monitored home training program for improving mobility skills in older novice manual wheelchair users, integrating principles from andragogy and social cognitive theory. The purpose of this study is to determine whether feasibility indicators and primary clinical outcome measures of the EPIC Wheels program are sufficiently robust to justify conducting a subsequent multi-site randomized controlled trial. A 2 × 2 factorial randomized controlled trial at two sites will compare improvement in wheelchair mobility skills between an EPIC Wheels treatment group and a computer-game control group, with additional wheelchair use introduced as a second factor. A total of 40 community-dwelling manual wheelchair users at least 55 years old and living in two Canadian metropolitan cities (n = 20 × 2) will be recruited. Feasibility indicators related to study process, resources, management, and treatment issues will be collected during data collection and at the end of the study period, and evaluated against proposed criteria. Clinical outcome measures will be collected at baseline (pre-randomization) and post-intervention. The primary clinical outcome measure is wheelchair skill capacity, as determined by the Wheelchair Skills Test, version 4.1. Secondary clinical outcome measures include wheelchair skill safety, satisfaction with performance, wheelchair confidence, life-space mobility, divided-attention, and health-related quality of life. The EPIC Wheels training program offers several innovative features. The convenient, portable, economical, and adaptable tablet-based, home program model for wheelchair skills training has great potential for clinical uptake and opportunity for future enhancements. Theory-driven design can foster learning and adherence for older adults. Establishing the feasibility of the study protocol and estimating effect size for the primary clinical outcome measure will be used to develop a multi-site randomized controlled trial to test the guiding hypotheses.

Informed by our prior work indicating that therapists do not feel recognized or rewarded for implementation of evidence-based practices, we tested the feasibility and acceptability of two incentive-based implementation strategies that seek to improve therapist adherence to cognitive-behavioral therapy for youth, an evidence-based practice. This study was conducted over 6 weeks in two community mental health agencies with therapists (n = 11) and leaders (n = 4). Therapists were randomized to receive either a financial or social incentive if they achieved a predetermined criterion on adherence to cognitive-behavioral therapy. In the first intervention period (block 1; 2 weeks), therapists received the reward they were initially randomized to if they achieved criterion. In the second intervention period (block 2; 2 weeks), therapists received both rewards if they achieved criterion. Therapists recorded 41 sessions across 15 unique clients over the project period. Primary outcomes included feasibility and acceptability. Feasibility was assessed quantitatively. Fifteen semi-structured interviews were conducted with therapists and leaders to assess acceptability. Difference in therapist adherence by condition was examined as an exploratory outcome. Adherence ratings were ascertained using an established and validated observational coding system of cognitive-behavioral therapy. Both implementation strategies were feasible and acceptable-however, modifications to study design for the larger trial will be necessary based on participant feedback. With respect to our exploratory analysis, we found a trend suggesting the financial reward may have had a more robust effect on therapist adherence than the social reward. Incentive-based implementation strategies can be feasibly administered in community mental health agencies with good acceptability, although iterative pilot work is essential. Larger, fully powered trials are needed to compare the effectiveness of implementation strategies to incentivize and enhance therapists' adherence to evidence-based practices such as cognitive-behavioral therapy.

To test feasibility of a guided audio-visual relaxation intervention protocol for reducing stress and pain in adults with sickle cell disease. Sickle cell pain is inadequately controlled using opioids, necessitating further intervention such as guided relaxation to reduce stress and pain. Attention-control, randomized clinical feasibility pilot study with repeated measures. Randomized to guided relaxation or control groups, all patients recruited between 2013-2014 during clinical visits, completed stress and pain measures via a Galaxy Internet-enabled Android tablet at the Baseline visit (pre/post intervention), 2-week posttest visit and also daily at home between the two visits. Experimental group patients were asked to use a guided relaxation intervention at the Baseline visit and at least once daily for 2 weeks. Control group patients engaged in a recorded sickle cell discussion at the Baseline visit. Data were analysed using linear regression with bootstrapping. At baseline, 27/28 of consented patients completed the study protocol. Group comparison showed that guided relaxation significantly reduced current stress and pain. At the 2-week posttest, 24/27 of patients completed the study, all of whom reported liking the study. Patients completed tablet-based measures on 71% of study days (69% in control group, 72% in experiment group). At the 2-week posttest, the experimental group had significantly lower composite pain index scores, but the two groups did not differ significantly on stress intensity. This study protocol appears feasible. The tablet-based guided relaxation intervention shows promise for reducing sickle cell pain and warrants a larger efficacy trial.

Evidence suggests that increasing intensity of rehabilitation results in better motor recovery. Limited evidence is available on the effectiveness of an interactive virtual reality gaming system for stroke rehabilitation. EVREST was designed to evaluate feasibility, safety and efficacy of using the Nintendo Wii gaming virtual reality (VRWii) technology to improve arm recovery in stroke patients. Pilot randomized study comparing, VRWii versus recreational therapy (RT) in patients receiving standard rehabilitation within six months of stroke with a motor deficit of > or =3 on the Chedoke-McMaster Scale (arm). In this study we expect to randomize 20 patients. All participants (age 18-85) will receive customary rehabilitative treatment consistent of a standardized protocol (eight sessions, 60 min each, over a two-week period). The primary feasibility outcome is the total time receiving the intervention. The primary safety outcome is the proportion of patients experiencing intervention-related adverse events during the study period. Efficacy, a secondary outcome measure, will be measured by the Wolf Motor Function Test, Box and Block Test, and Stroke Impact Scale at the four-week follow-up visit. From November, 2008 to September, 2009 21 patients were randomized to VRWii or RT. Mean age, 61 (range 41-83) years. Mean time from stroke onset 25 (range 10-56) days. EVREST is the first randomized parallel controlled trial assessing the feasibility, safety, and efficacy of virtual reality using Wii gaming technology in stroke rehabilitation. The results of this study will serve as the basis for a larger multicentre trial. ClinicalTrials.gov registration# NTC692523.

Premenstrual syndrome and premenstrual dysphoric disorder (PMS/PMDD) bother a substantial number of women. Homeopathy seems a promising treatment, but it needs investigation using reliable study designs. The feasibility of organizing an international randomized pragmatic trial on a homeopathic add-on treatment (usual care [UC] + HT) compared with UC alone was evaluated. A multicenter, randomized, controlled pragmatic trial with parallel groups. The study was organized in general and private homeopathic practices in the Netherlands and Sweden and in an outpatient university clinic in Germany. Women diagnosed as having PMS/PMDD, based on prospective daily rating by the daily record of severity of problems (DRSP) during a period of 2 months, were included and randomized. Women were to receive UC + HT or UC for 4 months. Homeopathic medicine selection was according to a previously tested prognostic questionnaire and electronic algorithm. Usual care was as provided by the women's general practitioner according to their preferences. Before and after treatment, the women completed diaries (DRSP), the measure yourself concerns and well-being, and other questionnaires. Intention-to-treat (ITT) and per protocol (PP) analyses were performed. In Germany, the study could not proceed because of legal limitations. In Sweden, recruitment proved extremely difficult. In the Netherlands and Sweden, 60 women were randomized (UC + HT: 28; UC: 32), data of 47/46 women were analyzed (ITT/PP). After 4 months, relative mean change of DRSP scores in the UC + HT group was significantly better than in the UC group (p = 0.03). With respect to recruitment and different legal status, it does not seem feasible to perform a larger, international, pragmatic randomized trial on (semi-)individualized homeopathy for PMS/PMDD. Since the added value of HT compared with UC was demonstrated by significant differences in symptom score changes, further studies are warranted.

To conduct generalizable, rigorously designed, adequately powered trials investigating music therapy and other complex interventions, it is essential that study procedures are feasible and acceptable for participants. To date, only limited evidence on feasibility of trial designs and strategies to facilitate study implementation is available in the music therapy literature. Using data from a subsample of a multi-center RCT on improvisational music therapy (IMT) for autism spectrum disorder (ASD), this study aims to evaluate feasibility of study procedures, evaluate safety, document concomitant treatment, and report consistency of individuals' trends over time in chosen outcome measures. Children with ASD aged between 4 years, 0 months, and 6 years, 11 months, were randomly assigned to one of three conditions: one (low intensity) vs. three weekly IMT sessions (high intensity) for five months vs. standard care. Feasibility was evaluated by examining recruitment, implementation of study conditions, assessment procedures, blinding, and retention; we also evaluated safety, concomitant treatment, and consistency of changes in standardized scales completed by blinded assessors and parents before and 5 months after randomization. Within this subsample (n = 15), recruitment rates, session attendance in the high-intensity condition, and consistency between outcome measures were lower than expected. Session attendance in the low-intensity and control conditions, treatment fidelity, measurement completion, blinding, retention, and safety met a priori thresholds for feasibility. By discussing strategies to improve recruitment and to minimize potential burden on study participants, referrers, and researchers, this study helps build knowledge about designing and implementing trials successfully. © the American Music Therapy Association 2016.

Convenience sampling methods predominate in recruiting for laboratory-based studies within clinical and family psychology. The authors used random digit dialing (RDD) to determine whether they could feasibly recruit generalizable samples for 2 studies (a parenting study and an intimate partner violence study). RDD screen response rate was 42-45%; demographics matched those in the 2000 U.S. Census, with small- to medium-sized differences on race, age, and income variables. RDD respondents who qualified for, but did not participate in, the laboratory study of parents showed small differences on income, couple conflicts, and corporal punishment. Time and cost are detailed, suggesting that RDD may be a feasible, effective method by which to recruit more generalizable samples for in-laboratory studies of family violence when those studies have sufficient resources.

This study investigates the feasibility of a Latin dance program in older Latinos with mild cognitive impairment (MCI) via a feasibility mixed methods randomized controlled design. Spanish-speaking older Latinos (N = 21, 75.4 [6.3] years old, 16 females/5 males, 22.4 [2.8] Mini-Mental State Examination [MMSE] score) were randomized into a 16-week dance intervention (BAILAMOS) or wait-list control; the control group crossed over at week 17 and received the dance intervention. Feasibility was determined by assessing reach, retention, attendance, dance logs, and postintervention focus groups. Reach was 91.3% of people who were screened and eligible. Program retention was 95.2%. The dropout rate was 42.8% (n = 9), and attendance for all participants was 55.76%. The focus group data revealed 4 themes: enthusiasm for dance, positive aspects of BAILAMOS, unfavorable aspects of BAILAMOS, and physical well-being after BAILAMOS. In conclusion, older Latinos with MCI find Latin dance as an enjoyable and safe mode of physical activity.

Human immunodeficiency virus (HIV) infection affects the quality of life of infected people. It is well known that empowerment is important for appropriate access to health care and quality of care. However, there is currently limited availability of explicit methods to increase the empowerment of HIV-infected people. This study aimed to develop and test the feasibility of a social self-value package as an empowerment intervention method for HIV-infected people. One group included 8-10 participants and each session lasted for one and half hours. Six sessions in total were developed and one session was conducted in one week. A total of 66 participants were randomly selected for participating in the package, assessed its feasibility both quantitatively and qualitatively. Attitudes towards HIV-related issues significantly and positively changed after each session. Client satisfaction and acceptability of the intervention was very high indicating high feasibility with good design. The qualitative findings also supported the quantitative findings where both participants and counselors accepted and were satisfied with the structure and contents of the package. This study revealed that providing an inclusive six-week social self-value package for HIV-infected Nepali people appears to be feasible. Its effect on empowerment intervention will be measured by a randomized controlled trial.

To determine the feasibility and efficacy of a home-based exercise intervention program to improve the functional performance of patients with Alzheimer's Disease (AD). Twenty-seven home-dwelling patients with AD were randomized to either an exercise intervention program delivered by their caregivers or a home safety assessment control. Measures of functional performance (primary), cognition, neuropsychiatric symptoms, quality of life and caregiver burden (secondary) were obtained at baseline and at 6 and 12 weeks following randomization. For each outcome measure, intent-to-treat analyses using linear random effects models were performed. Feasibility and adverse events were also assessed. Adherence to the exercise program was good. On the primary outcomes (functional performance) patients in the exercise group demonstrated a trend for improved performance on measures of hand function and lower extremity strength. On secondary outcome measures, trends toward worse depression and lower quality of life ratings were noted. The physical exercise intervention developed for the study, delivered by caregivers to home-dwelling patients with AD, was feasible and was associated with a trend for improved functional performance in this group of frail patients. Given the limited efficacy to date of pharmacotherapies for AD, further study of exercise intervention, in a variety of care setting, is warranted.

Vietnam is experiencing an epidemiologic transition with an increased prevalence of non-communicable diseases. At present, the major risk factors for cardiovascular disease (CVD) are either on the rise or at alarming levels in Vietnam; inasmuch, the burden of CVD will continue to increase in this country unless effective prevention and control measures are put in place. A national survey in 2008 found that the prevalence of hypertension (HTN) was approximately 25 % among Vietnamese adults and it increased with advancing age. Therefore, novel, large-scale, and sustainable interventions for public health education to promote engagement in the process of detecting and treating HTN in Vietnam are urgently needed. A feasibility randomized trial will be conducted in Hung Yen province, Vietnam to evaluate the feasibility and acceptability of a novel community-based intervention using the "storytelling" method to enhance the control of HTN in adults residing in four rural communities. The intervention will center on stories about living with HTN, with patients speaking in their own words. The stories will be obtained from particularly eloquent patients, or "video stars," identified during Story Development Groups. The study will involve two phases: (i) developing a HTN intervention using the storytelling method, which is designed to empower patients to facilitate changes in their lifestyle practices, and (ii) conducting a feasibility cluster-randomized trial to investigate the feasibility, acceptability, and potential efficacy of the intervention compared with usual care in HTN control among rural residents. The trial will be conducted at four communes, and within each commune, 25 individuals 50 years or older with HTN will be enrolled in the trial resulting in a total sample size of 100 patients. This feasibility trial will provide the necessary groundwork for a subsequent large-scale, fully powered, cluster-randomized controlled trial to test the efficacy of our novel community-based intervention. Results from the full-scale trial will provide health policy makers with practical evidence on how to combat a key risk factor for CVD using a feasible, sustainable, and cost-effective intervention that could be used as a national program for controlling HTN in Vietnam and other developing countries.

Background Observational studies indicate that higher volumes of physical activity are associated with improved disease outcomes among colon cancer survivors. The aim of this report is to describe the purpose, study design, methods, and recruitment results of the COURAGE trial, a National Cancer Institute (NCI) sponsored, phase II, randomized, dose-response exercise trial among colon cancer survivors. Methods/Results The primary objective of the COURAGE trial is to quantify the feasibility, safety, and physiologic effects of low-dose (150 min·wk−1) and high-dose (300 min·wk−1) moderate-intensity aerobic exercise compared to usual-care control group over six months. The exercise groups are provided with in-home treadmills and heart rate monitors. Between January and July 2015, 1,433 letters were mailed using a population-based state cancer registry; 126 colon cancer survivors inquired about participation, and 39 were randomized onto the study protocol. Age was associated with inquiry about study participation (P<0.001) and randomization onto the study protocol (P<0.001). No other demographic, clinical, or geographic characteristics were associated with study inquiry or randomization. The final trial participant was randomized in August 2015. Six month endpoint data collection was completed in February 2016. Discussion The recruitment of colon cancer survivors into an exercise trial is feasible. The findings from this trial will inform key design aspects for future phase 2 and phase 3 randomized controlled trials to examine the efficacy of exercise to improve clinical outcomes among colon cancer survivors.

Objectives A large percentage of children with autism spectrum disorders (ASD) have bedtime and sleep disturbances. However, the treatment of these disturbances has been understudied. The purpose of our study was to develop a manualized behavioral parent training (BPT) program for parents of young children with ASD and sleep disturbances and to test the feasibility, fidelity, and initial efficacy of the treatment in a small randomized controlled trial (RCT). Participants and methods Parents of a sample of 40 young children diagnosed with ASD with an average age of 3.5 years were enrolled in our study. Participants were randomized to either the BPT program group or a comparison group who were given nonsleep-related parent education. Each was individually administered a 5-session program delivered over the 8-week study. Outcome measures of feasibility, fidelity, and efficacy were collected at weeks 4 and 8 after the baseline time point. Children’s sleep was assessed by parent report and objectively by actigraphy. Results Of the 20 participants in each group, data were available for 15 participants randomized to BPT and 18 participants randomized to the comparison condition. Results supported the feasibility of the manualized parent training program and the comparison program. Treatment fidelity was high for both groups. The BPT program group significantly improved more than the comparison group based on the primary sleep outcome of parent report. There were no objective changes in sleep detected by actigraphy. Conclusions Our study is one of few RCTs of a BPT program to specifically target sleep disturbances in a well-characterized sample of young children with ASD and to demonstrate the feasibility of the approach. Initial efficacy favored the BPT program over the comparison group and suggested that this manualized parent training approach is worthy of further examination of the efficacy within a larger RCT.

Patients with "refractory angina" (RA) unsuitable for coronary revascularization experience high levels of hospitalization and poor health-related quality of life. Randomized trials have shown spinal cord stimulation (SCS) to be a promising treatment for chronic stable angina and RA; however, none has compared SCS with usual care (UC). The aim of this pilot study was to address the key uncertainties of conducting a definitive multicenter trial to assess the clinical and cost-effectiveness of SCS in RA patients, i.e., recruitment and retention of patients, burden of outcome measures, our ability to standardize UC in a UK NHS setting. RA patients deemed suitable were randomized in a 1:1 ratio to SCS plus UC (SCS group) or UC alone (UC group). We sought to assess: recruitment, uptake, and retention of patients; feasibility and acceptability of SCS treatment; the feasibility and acceptability of standardizing UC; and the feasibility and acceptability of the proposed trial outcome measures. Patient outcomes were assessed at baseline (prerandomization) and three and six months postrandomization. We failed to meet our planned recruitment target (45 patients) and randomized 29 patients (15 SCS group, 14 UC group) over a 42-month period across four sites. None of the study participants chose to withdraw following consent and randomization. With exception of two deaths, all completed evaluation at baseline and follow-up. Although the study was not formally powered to compare outcomes between groups, we saw a trend toward larger improvements in both primary and secondary outcomes in the SCS group. While patient recruitment was found to be challenging, levels of participant retention, outcome completion, and acceptability of SCS therapy were high. A number of lessons are presented in order to take forward a future definitive pragmatic randomized trial. © 2015 The Authors.

The handheld fan is an inexpensive and safe way to provide facial airflow, which may reduce the sensation of chronic refractory breathlessness, a frequently encountered symptom. To test the feasibility of developing an adequately powered, multicenter, multinational randomized controlled trial comparing the efficacy of a handheld fan and exercise advice with advice alone in increasing activity in people with chronic refractory breathlessness from a variety of medical conditions, measuring recruitment rates; data quality; and potential primary outcome measures. This was a Phase II, multisite, international, parallel, nonblinded, mixed-methods randomized controlled trial. Participants were centrally randomized to fan or control. All received breathlessness self-management/exercise advice and were followed up weekly for four weeks. Participants/carers were invited to participate in a semistructured interview at the study's conclusion. Ninety-seven people were screened, 49 randomized (mean age 68 years; 49% men), and 43 completed the study. Site recruitment varied from 0.25 to 3.3/month and screening:randomization from 1.1:1 to 8.5:1. There were few missing data except for the Chronic Obstructive Pulmonary Disease Self-Efficacy Scale (two-thirds of data missing). No harms were observed. Three interview themes included 1) a fan is a helpful self-management strategy, 2) a fan aids recovery, and 3) a symptom control trial was welcome. A definitive, multisite trial to study the use of the handheld fan as part of self-management of chronic refractory breathlessness is feasible. Participants found the fan useful. However, the value of information for changing practice or policy is unlikely to justify the expense of such a trial, given perceived benefits, the minimal costs, and an absence of harms demonstrated in this study.

Breast cancer patients receiving adjuvant chemotherapy often experience functional effects of treatment that limit participation in life activities. The purpose of this study was to examine the feasibility of conducting a randomized controlled trial (RCT) of a novel intervention for these restrictions, determine acceptability of the intervention, and preliminarily assess its effects. A pilot RCT of a telephone-delivered Problem-solving and Occupational Therapy intervention (PST-OT) to improve participation restrictions in rural breast cancer patients undergoing chemotherapy. Thirty-one participants with Stages 1-3 breast cancer were randomized to 6 weekly sessions of PST-OT (n = 15) and usual care (n = 16). The primary study outcome was the feasibility of conducting the trial. Secondary outcomes were functional, quality of life and emotional status as assessed at baseline, 6 and 12 weeks. Of 46 patients referred 31 were enrolled (67% recruitment rate), of which 6 participants withdrew (81% retention rate). Twenty-four participants completed all study-related assessments (77%). Ninety-two percent of PST-OT participants were highly satisfied with the intervention, and 92% reported PST-OT to be helpful/very helpful for overcoming participation restrictions. Ninety-seven percent of planned PST-OT treatment sessions were completed. Completion rates for PST-OT homework tasks were high. Measures of functioning, quality of life, and emotional state favored the PST-OT condition. This pilot study suggests that an RCT of the PST-OT intervention is feasible to conduct with rural breast cancer patients undergoing adjuvant chemotherapy and that PST-OT may have positive effects on function, quality of life, and emotional state. 2010 John Wiley & Sons, Ltd.

To assess the feasibility of a randomized controlled trial to evaluate music therapy as a home-based intervention for arm hemiparesis in stroke. A pilot feasibility randomized controlled trial, with cross-over design. Randomization by statistician using computer-generated, random numbers concealed in opaque envelopes. Participants' homes across Cambridgeshire, UK. Eleven people with stroke and arm hemiparesis, 3-60 months post stroke, following discharge from community rehabilitation. Each participant engaged in therapeutic instrumental music performance in 12 individual clinical contacts, twice weekly for six weeks. Feasibility was estimated by recruitment from three community stroke teams over a 12-month period, attrition rates, completion of treatment and successful data collection. Structured interviews were conducted pre and post intervention to establish participant tolerance and preference. Action Research Arm Test and Nine-hole Peg Test data were collected at weeks 1, 6, 9, 15 and 18, pre and post intervention by a blinded assessor. A total of 11 of 14 invited participants were recruited (intervention n = 6, waitlist n = 5). In total, 10 completed treatment and data collection. It cannot be concluded whether a larger trial would be feasible due to unavailable data regarding a number of eligible patients screened. Adherence to treatment, retention and interview responses might suggest that the intervention was motivating for participants. ClinicalTrials.gov identifier NCT 02310438.

Poor sleep quality is highly prevalent in patients with low back pain (LBP) and is associated with high levels of pain, psychological distress, and physical disability. Studies have reported a bidirectional relationship between sleep problems and intensity of LBP. Accordingly, effective management of LBP should address sleep quality. In addition, genetics has been found to significantly affect the prevalence of both LBP and insomnia. Our study aims to establish the feasibility of a trial exploring the efficacy of a web-based sleep quality intervention in people with LBP, with the genetic influences being controlled for. 30 twins (15 complete pairs) with subacute or chronic LBP (>6 weeks) will be recruited from the Australian Twin Registry. Participants will be randomly assigned to one of the two groups with each twin within a pair receiving either an interactive web-based sleep intervention based on cognitive behavioral therapy principles (intervention) or a web-based education program (control) for 6 weeks. The feasibility of the trial will be investigated with regard to recruitment rate, feasibility of data collection and outcome measure completion, contamination of intervention, acceptability and experience of intervention, and sample size requirement for the full trial. Patient outcomes will be collected electronically at baseline, immediately post-treatment, and at 3-months' follow-up post-randomization. This trial employs a robust design that will effectively control for the influence of genetics on treatment effect. Additionally, this study addresses sleep quality, a significant but under-explored issue in LBP. Results will inform the design and implementation of the definitive trial.

Social cognition difficulties in schizophrenia are seen as a barrier to recovery. Intervention tackling problems in this domain have the potential to facilitate functioning and recovery. Social Cognition and Interaction Training (SCIT) is a manual-based psychological therapy designed to improve social functioning in schizophrenia. The aim of this study is to evaluate the feasibility and acceptability of a modified version of SCIT for inpatient forensic wards. The potential benefits of the intervention were also assessed. This study is a randomized single blind controlled design, with participants randomized to receive SCIT (N = 21) or treatment as usual (TAU; N = 15). SCIT consisted of 8-week therapy sessions twice per week. Participants were assessed at week 0 and one week after the intervention on measures of social cognition. Feasibility was assessed through group attendance and attrition. Participant acceptability and outcome was evaluated through post-group satisfaction and achievement of social goals. The intervention was well received by all participants and the majority reported their confidence improved. The SCIT group showed a significant improvement in facial affect recognition compared to TAU. Almost all participants agreed they had achieved their social goal as a result of the intervention. It is feasible to deliver SCIT in a forensic ward setting; however, some adaptation to the protocol may need to be considered in order to accommodate for the reduced social contact within forensic wards. Practice of social cognition skills in real life may be necessary to achieve benefits to theory of mind and attributional style.

Few homeopathic complexes seemed to produce significant effects in osteoarthritis; still, individualized homeopathy remained untested. We evaluated the feasibility of conducting an efficacy trial of individualized homeopathy in osteoarthritis. A prospective, parallel-arm, double-blind, randomized, placebo-controlled pilot study was conducted from January to October 2014 involving 60 patients (homeopathy, n = 30; placebo, n = 30) who were suffering from acute painful episodes of knee osteoarthritis and visiting the outpatient clinic of Mahesh Bhattacharyya Homeopathic Medical College and Hospital, West Bengal, India. Statistically significant reduction was achieved in 3 visual analog scales (measuring pain, stiffness, and loss of function) and Osteoarthritis Research Society International scores in both groups over 2 weeks (P < .05); however, group differences were not significant (P > .05). Overall, homeopathy did not appear to be superior to placebo; still, further rigorous evaluation in this design involving a larger sample size seems feasible in future.

We propose a randomized controlled trial (RCT) examining the feasibility of square-stepping exercise (SSE) delivered as a home-based program for older adults with multiple sclerosis (MS). We will assess feasibility in the four domains of process, resources, management and scientific outcomes. The trial will recruit older adults (aged 60 years and older) with mild-to-moderate MS-related disability who will be randomized into intervention or attention control conditions. Participants will complete assessments before and after completion of the conditions delivered over a 12-week period. Participants in the intervention group will have biweekly meetings with an exercise trainer in the Exercise Neuroscience Research Laboratory and receive verbal and visual instruction on step patterns for the SSE program. Participants will receive a mat for home-based practice of the step patterns, an instruction manual, and a logbook and pedometer for monitoring compliance. Compliance will be further monitored through weekly scheduled Skype calls. This feasibility study will inform future phase II and III RCTs that determine the actual efficacy and effectiveness of a home-based exercise program for older adults with MS.

Problem gambling creates significant harm for the gambler and for concerned significant others (CSOs). While several studies have investigated the effects of individual cognitive behavioral therapy (CBT) for problem gambling, less is known about the effects of involving CSOs in treatment. Behavioral couples therapy (BCT) has shown promising results when working with substance use disorders by involving both the user and a CSO. This pilot study investigated BCT for problem gambling, as well as the feasibility of performing a larger scale randomized controlled trial. 36 participants, 18 gamblers and 18 CSOs, were randomized to either BCT or individual CBT for the gambler. Both interventions were Internet-delivered self-help interventions with therapist support. Both groups of gamblers improved on all outcome measures, but there were no differences between the groups. The CSOs in the BCT group lowered their scores on anxiety and depression more than the CSOs of those randomized to the individual CBT group did. The implications of the results and the feasibility of the trial are discussed.

Background After older adults experience episodes of poor health or are hospitalized, they may not return to pre-morbid eating behaviors. Furthermore, poor nutrition increases hospital readmission risk, but evidence-based interventions addressing these risks are limited. Objective The pilot study’s objective was to evaluate the feasibility of conducting a randomized controlled trial assessing a post-discharge home-delivered meals program’s impact on older adults’ nutritional intake and hospital readmissions and to assess patient acceptability and satisfaction with the program. The aims of the study were to 1) to evaluate successful recruitment, randomization, and retention of at least 80% of the 24 participants sought; 2) to compare the outcomes of hospital readmission and total daily caloric intake between participants in the intervention and control groups; and 3) to assess patient acceptability and satisfaction with the program. Design This study used a two-arm randomized controlled trial design, and baseline data were collected at enrollment; three 24-hour food recalls were collected during the intervention period; and health services utilization and intervention satisfaction was evaluated 45 days post-discharge. Participants/setting Twenty-four patients from the University of Alabama at Birmingham (UAB) Hospital’s Acute Care for Elders Unit were enrolled from May 2014 to June 2015. They were 65 or older, at risk of malnutrition, cognitively intact, able to communicate, discharged to a place where the patient or family was responsible for preparing meals, and diagnosed with congestive heart failure, chronic obstructive pulmonary disease, acute myocardial infarction, or pneumonia. Final analysis included 21 participants. Intervention The intervention group received 10 days of home-delivered meals and nutrition education; the control group received usual care and nutrition education. Main outcome measures The main outcome was intervention feasibility, measured by recruitment and retention goals. Hospital readmissions, caloric intake, and satisfaction with the intervention were also evaluated. Statistical analyses performed Univariate and bivariate parametric statistics were used to evaluate differences between groups. Goals for success were identified to assess feasibility of conducting a full-scale study, and outcomes were measured against the goals. Results 87.5% of randomized participants were retained for final data collection, indicating that this intervention study is feasible. There were no significant differences between groups for hospital readmissions; however, caloric intake during the intervention period was greater for intervention vs. control participants (1595 vs. 1235, p=.03). Participants were overwhelmingly satisfied (82–100% satisfied or very satisfied) with staff performance, meal quality, and delivery processes. Conclusions Conducting a randomized controlled trial to assess outcomes of providing home-delivered meals to older adults after hospital discharge in partnership with a small nonprofit organization is feasible and warrants future research.

Acute upper gastrointestinal bleeding (AUGIB) is the commonest reason for hospitalization with hemorrhage in the UK and the leading indication for transfusion of red blood cells (RBCs). Observational studies suggest an association between more liberal RBC transfusion and adverse patient outcomes, and a recent randomised trial reported increased further bleeding and mortality with a liberal transfusion policy. TRIGGER (Transfusion in Gastrointestinal Bleeding) is a pragmatic, cluster randomized trial which aims to evaluate the feasibility and safety of implementing a restrictive versus liberal RBC transfusion policy in adult patients admitted with AUGIB. The trial will take place in 6 UK hospitals, and each centre will be randomly allocated to a transfusion policy. Clinicians throughout each hospital will manage all eligible patients according to the transfusion policy for the 6-month trial recruitment period. In the restrictive centers, patients become eligible for RBC transfusion when their hemoglobin is < 8 g/dL. In the liberal centers patients become eligible for transfusion once their hemoglobin is < 10 g/dL. All clinicians will have the discretion to transfuse outside of the policy but will be asked to document the reasons for doing so. Feasibility outcome measures include protocol adherence, recruitment rate, and evidence of selection bias. Clinical outcome measures include further bleeding, mortality, thromboembolic events, and infections. Quality of life will be measured using the EuroQol EQ-5D at day 28, and the costs associated with hospitalization for AUGIB in the UK will be estimated. Consent will be sought from participants or their representatives according to patient capacity for use of routine hospital data and day 28 follow up. The study has ethical approval for conduct in England and Scotland. Results will be analysed according to a pre-defined statistical analysis plan and disseminated in peer reviewed publications to relevant stakeholders. The results of this study will inform the feasibility and design of a phase III randomized trial. PMID:23706959

The Pre-Consultation Educational Group INTERVENTION pilot study seeks to assess the feasibility and inform the optimal design for a definitive randomized controlled trial that aims to improve the quality of decision-making in postmastectomy breast reconstruction patients. This is a mixed-methods pilot feasibility randomized controlled trial that will follow a single-center, 1:1 allocation, two-arm parallel group superiority design. The University Health Network, a tertiary care cancer center in Toronto, Canada. Adult women referred to one of three plastic and reconstructive surgeons for delayed breast reconstruction or prophylactic mastectomy with immediate breast reconstruction. We designed a multi-disciplinary educational group workshop that incorporates the key components of shared decision-making, decision-support, and psychosocial support for cancer survivors prior to the initial surgical consult. The intervention consists of didactic lectures by a plastic surgeon and nurse specialist on breast reconstruction choices, pre- and postoperative care; a value-clarification exercise led by a social worker; and discussions with a breast reconstruction patient. Usual care includes access to an informational booklet, website, and patient volunteer if desired. Expected pilot outcomes include feasibility, recruitment, and retention targets. Acceptability of intervention and full trial outcomes will be established through qualitative interviews. Trial outcomes will include decision-quality measures, patient-reported outcomes, and service outcomes, and the treatment effect estimate and variability will be used to inform the sample size calculation for a full trial. Our pilot study seeks to identify the (1) feasibility, acceptability, and design of a definitive RCT and (2) the optimal content and delivery of our proposed educational group intervention. Thirty patients have been recruited to date (8 April 2013), of whom 15 have been randomized to one of three decision support workshops. The trial will close as planned in May 2013. NCT01857882.

The optimal time of rectal resection after long-course chemoradiotherapy (CRT) remains unclear. A feasibility study was undertaken for a multi-centre randomized controlled trial evaluating the impact of the interval after chemoradiotherapy on the technical complexity of surgery. Patients with rectal cancer were randomized to either a 6- or 12-week interval between CRT and surgery between June 2012 and May 2014 (ISRCTN registration number: 88843062). For blinded technical complexity assessment, the Observational Clinical Human Reliability Analysis technique was used to quantify technical errors enacted within video recordings of operations. Other measured outcomes included resection completeness, specimen quality, radiological down-staging, tumour cell density down-staging and surgeon-reported technical complexity. Thirty-one patients were enrolled: 15 were randomized to 6 and 16-12 weeks across 7 centres. Fewer eligible patients were identified than had been predicted. Of 23 patients who underwent resection, mean 12.3 errors were observed per case at 6 weeks vs. 10.7 at 12 weeks (p = 0.401). Other measured outcomes were similar between groups. The feasibility of measurement of operative performance of rectal cancer surgery as an endpoint was confirmed in this exploratory study. Recruitment of sufficient numbers of patients represented a challenge, and a proportion of patients did not proceed to resection surgery. These results suggest that interval after CRT may not substantially impact upon surgical technical performance.

Objective: To assess the feasibility of a randomized controlled trial to evaluate music therapy as a home-based intervention for arm hemiparesis in stroke. Design: A pilot feasibility randomized controlled trial, with cross-over design. Randomization by statistician using computer-generated, random numbers concealed in opaque envelopes. Setting: Participants’ homes across Cambridgeshire, UK. Subjects: Eleven people with stroke and arm hemiparesis, 3–60 months post stroke, following discharge from community rehabilitation. Interventions: Each participant engaged in therapeutic instrumental music performance in 12 individual clinical contacts, twice weekly for six weeks. Main measures: Feasibility was estimated by recruitment from three community stroke teams over a 12-month period, attrition rates, completion of treatment and successful data collection. Structured interviews were conducted pre and post intervention to establish participant tolerance and preference. Action Research Arm Test and Nine-hole Peg Test data were collected at weeks 1, 6, 9, 15 and 18, pre and post intervention by a blinded assessor. Results: A total of 11 of 14 invited participants were recruited (intervention n = 6, waitlist n = 5). In total, 10 completed treatment and data collection. Conclusion: It cannot be concluded whether a larger trial would be feasible due to unavailable data regarding a number of eligible patients screened. Adherence to treatment, retention and interview responses might suggest that the intervention was motivating for participants. Trial registration: ClinicalTrials.gov identifier NCT 02310438.

Low physical activity level is associated with poor prognosis in patients with colorectal cancer (CRC). To increase physical activity, technology-based platforms are emerging and provide intriguing opportunities to prescribe and monitor active lifestyle interventions. The "Interval Walking in Colorectal Cancer"(I-WALK-CRC) study explores the feasibility and efficacy a home-based interval-walking intervention delivered by a smart-phone application in order to improve cardio-metabolic health profile among CRC survivors. The aim of the present report is to describe the design, methods and recruitment results of the I-WALK-CRC study.Methods/Results: The I-WALK-CRC study is a randomized controlled trial designed to evaluate the feasibility and efficacy of a home-based interval walking intervention compared to a waiting-list control group for physiological and patient-reported outcomes. Patients who had completed surgery for local stage disease and patients who had completed surgery and any adjuvant chemotherapy for locally advanced stage disease were eligible for inclusion. Between October 1st , 2015, and February 1st , 2017, 136 inquiries were recorded; 83 patients were eligible for enrollment, and 42 patients accepted participation. Age and employment status were associated with participation, as participants were significantly younger (60.5 vs 70.8 years, P < 0.001) and more likely to be working (OR 5.04; 95%CI 1.96-12.98, P < 0.001) than non-participants. In the present study, recruitment of CRC survivors was feasible but we aim to better the recruitment rate in future studies. Further, the study clearly favored younger participants. The I-WALK-CRC study will provide important information regarding feasibility and efficacy of a home-based walking exercise program in CRC survivors.
Tablet-Based Intervention for Reducing Children's Preoperative Anxiety: A Pilot Study.
Chow, Cheryl H T; Van Lieshout, Ryan J; Schmidt, Louis A; Buckley, Norman
To examine the feasibility, acceptability, and effects of a novel tablet-based application, Story-Telling Medicine (STM), in reducing children's preoperative anxiety. Children (N = 100) aged 7 to 13 years who were undergoing outpatient surgery were recruited from a local children's hospital. This study comprised 3 waves: Waves 1 (n = 30) and 2 (n = 30) examined feasibility, and Wave 3 (n = 40) examined the acceptability of STM and compared its effect on preoperative anxiety to Usual Care (UC). In Wave 3, children were randomly allocated to receive STM+UC or UC. A change in preoperative anxiety was measured using the Children's Perioperative Multidimensional Anxiety Scale (CPMAS) 7 to 14 days before surgery (T1), on the day of surgery (T2), and 1 month postoperatively (T3). Wave 1 demonstrated the feasibility of participant recruitment and data collection procedures but identified challenges with attrition at T2 and T3. Wave 2 piloted a modified protocol that addressed attrition and increased the feasibility of follow-up. In Wave 3, children in the STM+UC demonstrated greater reductions in CPMAS compared with the UC group (ΔM = 119.90, SE = 46.36, t(27) = 2.59, p = .015; 95% confidence interval = 24.78-215.02). This pilot study provides preliminary evidence that STM is a feasible and acceptable intervention for reducing children's preoperative anxiety in a busy pediatric operative setting and supports the investigation of a full-scale randomized controlled trial.

Background Many older adults rely on a manual wheelchair for mobility but typically receive little, if any, training on how to use their wheelchair effectively and independently. Standardized skill training is an effective intervention, but limited access to clinician trainers is a substantive barrier. Enhancing Participation in the Community by Improving Wheelchair Skills (EPIC Wheels) is a 1-month monitored home training program for improving mobility skills in older novice manual wheelchair users, integrating principles from andragogy and social cognitive theory. The purpose of this study is to determine whether feasibility indicators and primary clinical outcome measures of the EPIC Wheels program are sufficiently robust to justify conducting a subsequent multi-site randomized controlled trial. Methods A 2 × 2 factorial randomized controlled trial at two sites will compare improvement in wheelchair mobility skills between an EPIC Wheels treatment group and a computer-game control group, with additional wheelchair use introduced as a second factor. A total of 40 community-dwelling manual wheelchair users at least 55 years old and living in two Canadian metropolitan cities (n = 20 × 2) will be recruited. Feasibility indicators related to study process, resources, management, and treatment issues will be collected during data collection and at the end of the study period, and evaluated against proposed criteria. Clinical outcome measures will be collected at baseline (pre-randomization) and post-intervention. The primary clinical outcome measure is wheelchair skill capacity, as determined by the Wheelchair Skills Test, version 4.1. Secondary clinical outcome measures include wheelchair skill safety, satisfaction with performance, wheelchair confidence, life-space mobility, divided-attention, and health-related quality of life. Discussion The EPIC Wheels training program offers several innovative features. The convenient, portable, economical, and adaptable tablet-based, home program model for wheelchair skills training has great potential for clinical uptake and opportunity for future enhancements. Theory-driven design can foster learning and adherence for older adults. Establishing the feasibility of the study protocol and estimating effect size for the primary clinical outcome measure will be used to develop a multi-site randomized controlled trial to test the guiding hypotheses.

To examine the feasibility of a randomized controlled study design and to explore the benefits of a set dancing intervention compared with usual care. Randomized controlled design, with participants randomized to Irish set dance classes or a usual care group. Community based. Individuals with idiopathic Parkinson disease (PD) (N=90). The dance group attended a 1.5-hour dancing class each week for 10 weeks and undertook a home dance program for 20 minutes, 3 times per week. The usual care group continued with their usual care and daily activities. The primary outcome was feasibility, determined by recruitment rates, success of randomization and allocation procedures, attrition, adherence, safety, willingness of participants to be randomized, resource availability, and cost. Secondary outcomes were motor function (motor section of the Unified Parkinson's Disease Rating Scale), quality of life (Parkinson's Disease Questionnaire-39), functional endurance (6-min walk test), and balance (mini-BESTest). Ninety participants were randomized (45 per group). There were no adverse effects or resource constraints. Although adherence to the dancing program was 93.5%, there was >40% attrition in each group. Postintervention, the dance group had greater nonsignificant gains in quality of life than the usual care group. There was a meaningful deterioration in endurance in the usual care group. There were no meaningful changes in other outcomes. The exit questionnaire showed participants enjoyed the classes and would like to continue participation. For people with mild to moderately severe PD, set dancing is feasible and enjoyable and may improve quality of life. Copyright © 2016 American Congress of Rehabilitation Medicine.

Cardiovascular disease (CVD) is markedly increased among hemodialysis (HD) patients. Optimizing blood pressure (BP) among HD patients may present an important opportunity to reduce the disparity in CVD rates between HD patients and the general population. The optimal target predialysis systolic BP (SBP) among HD patients is unknown. Current international guidelines, calling for a predialysis SBP < 140 mm Hg, are based on the opinion and extrapolation from the general population. Existing randomized controlled trials (RCTs) were small and did not include prespecified BP targets. The authors described the design of the Blood Pressure in Dialysis (BID) Study, a pilot, multicenter RCT where HD patients are randomized to either a target-standardized predialysis SBP of 110 to 140 mm Hg or 155 to 165 mm Hg. This is the first study to randomize HD patients to 2 different SBP targets. Primary outcomes are feasibility and safety. Feasibility parameters include recruitment and retention rates, adherence with prescribed BP measurements and achievement and maintenance of selected BP targets. Safety parameters include rates of hypotension and other adverse and serious adverse events. The authors obtained preliminary data on changes in left ventricular mass, aortic pulse wave velocity, vascular access thromboses and health-related quality of life across study arms, which may be the secondary outcomes in the full-scale study. The data acquired in the pilot RCT will determine the feasibility and safety and inform the design of a full-scale trial, powered for hard outcomes, which may require 2000 participants.

The purpose of this study was to test the feasibility and effectiveness of an adapted 8-week Mindfulness-Based Stress Reduction (MBSR) program for elders in a continuing care community. This mixed-methods study used both quantitative and qualitative measures. A randomized waitlist control design was used for the quantitative aspect of the study. Thirty-nine elderly were randomized to MBSR (n = 20) or a waitlist control group (n = 19), mean age was 82 years. Both groups completed pre-post measures of health-related quality of life, acceptance and psychological flexibility, facets of mindfulness, self-compassion, and psychological distress. A subset of MBSR participants completed qualitative interviews. MBSR participants showed significantly greater improvement in acceptance and psychological flexibility and in role limitations due to physical health. In the qualitative interviews, MBSR participants reported increased awareness, less judgment, and greater self-compassion. Study results demonstrate the feasibility and potential effectiveness of an adapted MBSR program in promoting mind-body health for elders. © The Author(s) 2014.

Background Wireless electronic adherence monitors can detect antiretroviral therapy (ART) adherence lapses and trigger interventions in real time, thus potentially avoiding unnecessary HIV viremia. Evidence about the acceptability and feasibility of these monitors and associated interventions, however, is limited. Objective The aim of this study was to assess the acceptability and feasibility of real-time adherence monitoring linked to text messaging (short message service, SMS) reminders and notifications to support adherence among individuals living with HIV who are taking ART in rural southwestern Uganda. Methods Individuals living with HIV who were initiating ART were enrolled in a pilot randomized controlled trial and followed up for 9 months. Participants received a real-time adherence monitor and were randomized to one of the following study arms: (1) scheduled SMS, (2) SMS triggered by missed or delayed doses, or (3) no SMS. SMS notifications were also sent to 45 patient-identified social supporters for sustained adherence lapses in the scheduled SMS and triggered SMS arms. Study participants and social supporters participated in qualitative semistructured in-depth interviews on acceptability and feasibility of this technology. An inductive, content analytic approach, framed by the unified theory of acceptance and use of technology model, was used to analyze qualitative data. Quantitative feasibility data, including device functionality and SMS tracking data, were recorded based upon device metrics collected electronically and summarized descriptively. Results A total of 63 participants participated in the study. Participants reported that real-time monitoring intervention linked to SMS reminders and notifications are generally acceptable; the predominant feedback was perceived utility—the intervention was beneficial in motivating and reminding patients to take medication, as well as enabling provision of social support. The intervention was found to be technically feasible, as data were obtained from most participants as expected most of the time. Potential challenges included the impact of the technology on confidentiality, shared phone ownership, usability skills, and availability of electricity. Conclusions Real-time adherence monitoring integrated with SMS reminders and social support notifications is a generally acceptable (based primarily on perceived utility) and feasible intervention in a resource-limited country. Future efforts should focus on optimized device design, user training to overcome the challenges we encountered, cost effectiveness studies, as well as studying the monitoring aspect of the device without accompanying interventions.

To estimate feasibility and potential for efficacy of an individualized, exercise-focused, self-management program (i.e. Managing Mobility Outcomes In Vulnerable Seniors ( MMOVeS)), in comparison to exercise information in improving mobility after six months among seniors recently discharged from hospital. Randomized pilot study. Two McGill University-teaching hospitals. Community dwelling seniors, aged 70 years and older, recently discharged from either participating hospitals. The physiotherapy-facilitated intervention consisted of (1) evaluation of mobility capacity, (2) setting short- and long-term goals, (3) delineation of an exercise treatment plan, (4) an educational booklet to enhance mobility self-management skills, and (5) six monthly telephone calls. Control group received a booklet with information on exercises targeting mobility limitations in seniors. Mobility, pain, and health status were assessed at baseline and at six months using multiple indicators drawn from Disabilities of the Arm, Shoulder, and Hand (DASH) Score, Lower Extremity Functional Scale (LEFS) and Short-Form (SF)-36. In all, 26 people were randomized to the intervention (mean age: 81 ± 8; 39% women), and 23 were randomized to the control (mean age: 79 ± 7; 33% women). The odds ratio for the mobility outcomes combined was 3.08 and the 95% confidence interval excluded 1 (1.65-5.77). The odds ratio for pain and health perception favored the MMOVeS group, but the 95% confidence interval included the null value. This feasibility study highlights the potential for efficacy of an individualized, exercise-focused, self-management program in comparison to exercise information in improving mobility outcome for seniors. Furthermore, a home-program combining self-management skills and exercise taught with minimal supervision prove to be feasible. Finally, data from this study can be used to estimate sample size for a confirmatory trial.

PURPOSE.: The purpose of the study was to examine the feasibility and initial efficacies of parent- and/or child-focused online interventions and variables correlated with child body mass index percentile change. DESIGN AND METHODS.: A feasibility and cluster randomized controlled pilot study was used. RESULTS.: Recruitment was more effective at parent-teacher conferences compared with when materials were sent home with fifth- to eighth-grade culturally diverse students. Retention was 90% for students and 62-74% for parents. Authoritative parent feeding behaviors were associated with lower child body mass index. A larger study is warranted. PRACTICE IMPLICATIONS.: Online approaches may provide a feasible option for childhood obesity prevention and amelioration. © 2013, Wiley Periodicals, Inc.

Major depressive disorder is often comorbid with diabetes and associated with worse glycemic control. Exercise improves glycemic control and depression, and thus could be a parsimonious intervention for patients with comorbid diabetes and major depression. Because patients with diabetes and comorbid depression are often sedentary and lack motivation to exercise, we developed a group exercise intervention that integrates strategies from behavioral activation therapy for depression to increase motivation for and enjoyment of exercise. We conducted a 6-month pilot randomized controlled trial to test the feasibility of the behavioral activation exercise intervention (EX) for women with diabetes and depression. Of the 715 individuals who contacted us about the study, 29 participants were randomized to the EX condition or an enhanced usual care condition (EUC), which represents 4.1% of participants who initially contacted us. Inclusion criteria made recruitment challenging and limits the feasibility of recruiting women with diabetes and depression for a larger trial of the intervention. Retention was 96.5% and 86.2% at 3 and 6 months. Participants reported high treatment acceptability; use of behavioral activation strategies and exercise class attendance was acceptable. No condition differences were observed for glycemic control, depressive symptoms, and physical activity, though depressive symptoms and self-reported physical activity improved over time. Compared to participants in the EUC condition, participants in the EX condition reported greater exercise enjoyment and no increase in avoidance behavior over time. Using behavioral activation strategies to increase exercise is feasible in a group exercise setting. However, whether these strategies can be delivered in a less intensive manner to a broader population of sedentary adults, for greater initiation and maintenance of physical activity, deserves further study.

Cancer cachexia is a syndrome of weight loss (including muscle and fat), anorexia, and decreased physical function. It has been suggested that the optimal treatment for cachexia should be a multimodal intervention. The primary aim of this study was to examine the feasibility and safety of a multimodal intervention (n-3 polyunsaturated fatty acid nutritional supplements, exercise, and anti-inflammatory medication: celecoxib) for cancer cachexia in patients with incurable lung or pancreatic cancer, undergoing chemotherapy. Patients receiving two cycles of standard chemotherapy were randomized to either the multimodal cachexia intervention or standard care. Primary outcome measures were feasibility assessed by recruitment, attrition, and compliance with intervention (>50% of components in >50% of patients). Key secondary outcomes were change in weight, muscle mass, physical activity, safety, and survival. Three hundred and ninety-nine were screened resulting in 46 patients recruited (11.5%). Twenty five patients were randomized to the treatment and 21 as controls. Forty-one completed the study (attrition rate 11%). Compliance to the individual components of the intervention was 76% for celecoxib, 60% for exercise, and 48% for nutritional supplements. As expected from the sample size, there was no statistically significant effect on physical activity or muscle mass. There were no intervention-related Serious Adverse Events and survival was similar between the groups. A multimodal cachexia intervention is feasible and safe in patients with incurable lung or pancreatic cancer; however, compliance to nutritional supplements was suboptimal. A phase III study is now underway to assess fully the effect of the intervention. © 2017 The Authors.

Stroke results in significant disability, which can be reduced by physical rehabilitation. High levels of repetition and activity are required in rehabilitation, but patients are typically sedentary. Using clinically relevant and fun computer games may be one way to achieve increased activity in rehabilitation. A single-blind randomized controlled trial will be conducted to evaluate the feasibility, efficacy and safety of novel stroke-specific rehabilitation software. This software uses controller-free client interaction and inertial motion sensors. Elements of feasibility include recruitment into the trial, ongoing participation (adherence and dropout), perceived benefit, enjoyment and ease of use of the games. Efficacy will be determined by measuring activity and using upper-limb tasks as well as measures of balance and mobility. The hypothesis that the intervention group will have increased levels of physical activity within rehabilitation and improved physical outcomes compared with the control group will be tested. Results from this study will provide a basis for discussion of feasibility of this interactive video technological solution in an inpatient situation. Differences in activity levels between groups will be the primary measure of efficacy. It will also provide data on measures of upper-limb function, balance and mobility. ACTRN12614000427673 .

To evaluate the feasibility of conducting a randomized clinical trial of an Internet-based manualized intervention to teach individuals with traumatic brain injury to manage their fatigue. Community dwelling. Forty-one participants randomized to Maximizing Energy (MAX) intervention group (n = 20) and Health Education group (n = 21). The experimental group (MAX intervention) received an 8-week program that combined education and Problem-Solving Therapy to teach individuals to manage fatigue-related problems. The attention control group received health education. Primary outcome measures pertained to the feasibility of conducting the trial. Secondary outcomes were fatigue impact and fatigue severity assessed at baseline and postintervention. Of the 65 participants referred, 41 were enrolled (63% recruitment rate), of which 3 withdrew (92% retention rate). Participants in the experimental and control groups completed their homework 75% and 85% of the time, respectively, and were equally engaged in the sessions. Participants in the experimental group were able to learn and implement the MAX intervention steps. Effect sizes for all measures ranged from small (-0.17) to medium (-0.58) in favor of the intervention group. Findings from the study suggest that the MAX intervention is feasible to administer to individuals with post-traumatic brain injury fatigue.

The burden of chronic pain is a major challenge, impacting the quality of life of patients. Intensive programmes of mindfulness-based therapy can help patients to cope with chronic pain but can be time consuming and require a trained specialist to implement. The self-management model of care is now integral to the care of patients with chronic pain; home-based interventions can be very acceptable, making a compelling argument for investigating brief, self-management interventions. The aim of this study is two-fold: to assess the immediate effects of a brief self-help mindfulness intervention for coping with chronic pain and to assess the feasibility of conducting a definitive randomized controlled trial to determine the effectiveness of such an intervention. A randomized controlled pilot study will be conducted to evaluate a brief mindfulness intervention for those with chronic pain. Ninety chronic pain patients who attend hospital outpatient clinics will be recruited and allocated randomly to either the control or treatment group on a 1:1 basis using the computer-generated list of random numbers. The treatment group receives mindfulness audios and the control group receives audios of readings from a non-fiction book, all of which are 15 minutes in length. Immediate effects of the intervention are assessed with brief psychological measures immediately before and after audio use. Mindfulness, mood, health-related quality of life, pain catastrophizing and experience of the intervention are assessed with standardized measures, brief ratings and brief telephone follow-ups, at baseline and after one week and one month. Feasibility is assessed by estimation of effect sizes for outcomes, patient adherence and experience, and appraisal of resource allocation in provision of the intervention. This trial will assess whether a brief mindfulness-based intervention is effective for immediately reducing perceived distress and pain with the side effect of increasing relaxation in chronic pain patients and will determine the feasibility of conducting a definitive randomized controlled trial. Patient recruitment began in January 2015 and is due to be completed in June 2016. ISRCTN61538090 Registered 20 April 2015.

There are no biological treatments for fetal alcohol spectrum disorders (FASDs), lifelong conditions associated with physical anomalies, brain damage, and neurocognitive abnormalities. In preclinical studies, choline partially ameliorates memory and learning deficits from prenatal alcohol exposure. This phase I pilot study evaluated the feasibility, tolerability, and potential adverse effects of choline supplementation in children with FASD. We hypothesized that choline would be well tolerated with minimal adverse events. The study design was a double-blind, randomized, placebo-controlled trial. Participants included 20 children aged 2.5 to 4.9 years with prenatal alcohol exposure and FASD diagnoses. Participants were randomly assigned to 500 mg choline or placebo daily for 9 months (10 active, 10 placebo). Primary outcome measures included feasibility, tolerability, adverse effects, and serum choline levels. Seventeen participants completed the study. Compliance was 82% to 87%, as evidenced by parent-completed log sheets and dose counts. Periodic 24-hour dietary recalls showed no evidence of dietary confounding. Adverse events were minimal and were equivalent in the active and placebo arms with the exception of fishy body odor, which occurred only in the active group. There were no serious adverse events to research participants. This phase I pilot study demonstrates that choline supplementation at 500 mg/d for 9 months in children aged 2 to 5 years is feasible and has high tolerability. Further examination of the efficacy of choline supplementation in FASD is currently underway. © 2013.

Neck pain in adults is common and a leading cause of physical disability. Recently, a guideline was developed for the management of non-specific neck pain (NSNP) with an aim to improve the quality of the delivery of chiropractic care. One key guideline recommendation is to undertake multimodal care for patients with NSNP. The aim of this pilot study is to determine the feasibility of implementing a multifaceted knowledge translation intervention by promoting the use of multimodal care by chiropractors managing patients with NSNP. The design is a cluster-randomized controlled pilot and feasibility trial. Chiropractors in private practice in Canada will be approached to participate in the study. Thirty consenting chiropractors will be randomized to receive either a theory-based educational intervention in the experimental group or simply a printed copy of the guideline in the control group. Each chiropractor will recruit five neck pain patients (a total of 150 patients) into the study. Development of the multifaceted intervention was informed by the results of a related qualitative study based on the Theoretical Domains Framework and consists of a series of three webinars, two online case scenarios, a self-management video on Brief Action Planning, and a printed copy of the practice guideline. Primary feasibility outcomes for both chiropractors and patients include rates of (1) recruitment, (2) retention, and (3) adherence to the intervention. A checklist of proxy measures embedded within patient encounter forms will be used to assess chiropractors' compliance with guideline recommendations (e.g. exercise and self-care prescriptions) at study onset and at 3 months. Secondary outcomes include scores of behavioural constructs (level of knowledge and self-efficacy) for recommended multimodal care. Clinical outcomes include pain intensity and neck pain-specific disability. Analyses from this study will focus on generating point estimates and corresponding 95 % confidence intervals for parameters of a priori interest (recruitment, retention, adherence, pain intensity, Neck Disability Index). Results of this study will inform the design of a larger cluster-randomized controlled trial aimed at evaluating the effectiveness of the theory-based tailored intervention and increasing the use of multimodal care by chiropractors managing patients with NSNP. https://clinicaltrials.gov/, NCT02483091.

Abstract Background. Self-management and self-efficacy for physical activity is not routinely considered in neurologic rehabilitation. Objective. This study assessed feasibility and outcomes of a 14-week physical activity self-management and coaching intervention compared with social contact in Huntington disease (HD) to inform the design of a future full-scale trial. Design. Assessor blind, multisite, randomized pilot feasibility trial. Setting. Participants were recruited and assessed at baseline, 16 weeks following randomization, and then again at 26 weeks in HD specialist clinics with intervention delivery by trained coaches in the participants’ homes. Patients and Intervention. People with HD were allocated to the ENGAGE-HD physical activity coaching intervention or a social interaction intervention. Measurements. Eligibility, recruitment, retention, and intervention participation were determined at 16 weeks. Other outcomes of interest included measures of mobility, self-efficacy, physical activity, and disease-specific measures of motor and cognition. Fidelity and costs for both the physical activity and social comparator interventions were established. Results. Forty percent (n = 46) of eligible patients were enrolled; 22 were randomized to the physical intervention and 24 to social intervention. Retention rates in the physical intervention and social intervention were 77% and 92%, respectively. Minimum participation criteria were achieved by 82% of participants in the physical intervention and 100% in the social intervention. There was no indication of between-group treatment effects on function; however, increases in self-efficacy for exercise and self-reported levels of physical activity in the physical intervention lend support to our predefined intervention logic model. Limitations. The use of self-report measures may have introduced bias. Conclusions. An HD physical activity self-management and coaching intervention is feasible and worthy of further investigation.

There is an association among postural instability, gait dysfunction, and cognitive impairment in subjects with Parkinson's disease (PD). Difficulty in dividing attention, response inhibition, and visuospatial attention deficiencies may contribute to the impairment of motor performance during daily activities. There are strong evidences that physical therapy can prevent physical and cognitive decline in individuals with PD. Recently, the European Physiotherapy Guideline (EPG) was developed based on randomized clinical trials about the effectiveness of the physical therapy to improve the functional deficiencies of individuals with PD. The EPG did not include the use of promising new intervention as virtual reality in PD due the lack of studies about its safety, feasibility and effectiveness. Therefore, this study protocol had as objective to evaluate the feasibility, safety and effectiveness of a physical therapy program-based on the European Physiotherapy Guideline (EPG) compared to Kinect-based training on postural control, gait, cognition, and quality of life (QoL) of Individuals with PD. A single-blind, parallel, randomized, controlled feasibility trial will be conducted with a sample of 32 individuals diagnosed with idiopathic PD. Participants will be allocated into control group (CG) and experimental group (EG). The intervention of the CG will be conventional physical therapy, and the intervention of the EG will be a supervised practice of five Kinect games. Both groups will perform 14 sessions of 1 h each one, twice a week over 7 weeks. Process outcomes will be safety, feasibility, adherence, and acceptability. Safety will be assessed by the proportion of participants who experienced intervention-related adverse events or any serious adverse event during the study period. Feasibility will be assessed through the scores of the games recorded in all training sessions. Adherence will be assessed through the participant's attendance. Acceptability will be the motivation of the participants regarding the interventions. Clinical outcomes will be (1) postural control, (2) cognitive function, (3) balance, (4) gait, and (5) QoL. Individuals will be assessed pre- and post-interventions and after 30 days by a blinded evaluator. This protocol will clarify if an intervention based on Kinect games will be feasible, safe, and acceptable for individuals with PD compared to conventional physical therapy. We will verify whether the proposed interventions can improve clinical outcomes as postural control, gait, cognition, and QoL of individuals with PD. Our hypothesis is that both Kinect games and conventional physical therapy will be feasible, safe, and acceptable for individuals with PD and will promote positive clinical effects. The results of this feasibility study will be used to design a future definitive clinical trial. Unique identification number in WHO Trial Registration: U1111-1171-0371.

To test the feasibility of Kids SIP smartER, a school-based intervention to reduce consumption of sugar-sweetened beverages (SSBs). Matched-contact randomized crossover study with mixed-methods analysis. One middle school in rural, Appalachian Virginia. Seventy-four sixth and seventh graders (5 classrooms) received Kids SIP smartER in random order over 2 intervention periods. Feasibility outcomes were assessed among 2 teachers. Kids SIP smartER consisted of 6 lessons grounded in the Theory of Planned Behavior, media literacy, and public health literacy and aimed to improve individual SSB behaviors and understanding of media literacy and prevalent regional disparities. The matched-contact intervention promoted physical activity. Beverage Intake Questionnaire-15 (SSB consumption), validated theory questionnaires, feasibility questionnaires (student and teacher), student focus groups, teacher interviews, and process data (eg, attendance). Repeated measures analysis of variances across 3 time points, descriptive statistics, and deductive analysis of qualitative data. During the first intervention period, students receiving Kids SIP smartER (n = 43) significantly reduced SSBs by 11 ounces/day ( P = .01) and improved media ( P < .001) and public health literacy ( P < .01) understanding; however, only media literacy showed between-group differences ( P < .01). Students and teachers found Kids SIP smartER acceptable, in-demand, practical, and implementable within existing resources. Kids SIP smartER is feasible in an underresourced, rural school setting. Results will inform further development and large-scale testing of Kids SIP smartER to reduce SSBs among rural adolescents.

Objective To test the feasibility of a randomized-controlled trial measuring the impact of an adapted mindfulness-based intervention (MBI) in female adolescents with chronic pain. Methods This was a single center, single-blind, prospective, experimental, longitudinal trial conducted in a pediatric tertiary care center. Participants had a history of chronic pain during at least three months. They were randomized into an intervention group or a wait-list control group. Both groups successively followed an adapted eight-week MBI designed specifically for adolescents with chronic pain. Pre-determined criteria were established to assess the feasibility, validity and acceptability of the study model. Data evaluating changes in quality of life, depression, anxiety, pain perception, psychological distress and salivary cortisol were collected throughout the 4-month study period. Results Nineteen female participants completed the study and had a mean age of 15.8 years (range 13.9 -17.8). Attrition rate was low (17%). Attendance to mindfulness sessions (84%) and compliance to study protocol (100%) were high. All participants reported a positive change in the way they coped with pain. No changes in quality of life, depression, anxiety, pain perception, and psychological distress were detected. Significant reductions in pre-and post-mindfulness session salivary cortisol levels were observed (p<0.001). Conclusions Mindfulness is a promising therapeutic approach for which limited data exist in adolescents with chronic pain. Our study indicates the feasibility of conducting such interventions in teenage girls. A large trial is needed to demonstrate the efficacy and bio-physiological impacts of MBIs in teenagers with chronic pain. PMID:27924146

In the USA, stillbirth (in utero fetal death ≥20 weeks gestation) is a major public health issue. Women who experience stillbirth, compared to women with live birth, have a nearly sevenfold increased risk of a positive screen for post-traumatic stress disorder (PTSD) and a fourfold increased risk of depressive symptoms. Because the majority of women who have experienced the death of their baby become pregnant within 12-18 months and the lack of intervention studies conducted within this population, novel approaches targeting physical and mental health, specific to the needs of this population, are critical. Evidence suggests that yoga is efficacious, safe, acceptable, and cost-effective for improving mental health in a variety of populations, including pregnant and postpartum women. To date, there are no known studies examining online-streaming yoga as a strategy to help mothers cope with PTSD symptoms after stillbirth. The present study is a two-phase randomized controlled trial. Phase 1 will involve (1) an iterative design process to develop the online yoga prescription for phase 2 and (2) qualitative interviews to identify cultural barriers to recruitment in non-Caucasian women (i.e., predominately Hispanic and/or African American) who have experienced stillbirth ( N = 5). Phase 2 is a three-group randomized feasibility trial with assessments at baseline, and at 12 and 20 weeks post-intervention. Ninety women who have experienced a stillbirth within 6 weeks to 24 months will be randomized into one of the following three arms for 12 weeks: (1) intervention low dose (LD) = 60 min/week online-streaming yoga ( n = 30), (2) intervention moderate dose (MD) = 150 min/week online-streaming yoga ( n = 30), or (3) stretch and tone control (STC) group = 60 min/week of stretching/toning exercises ( n = 30). This study will explore the feasibility and acceptability of a 12-week, home-based, online-streamed yoga intervention, with varying doses among mothers after a stillbirth. If feasible, the findings from this study will inform a full-scale trial to determine the effectiveness of home-based online-streamed yoga to improve PTSD. Long-term, health care providers could use online yoga as a non-pharmaceutical, inexpensive resource for stillbirth aftercare. NCT02925481.

Abstract Background: Delivering specialty care remotely directly into people's homes can enhance access for and improve the healthcare of individuals with chronic conditions. However, evidence supporting this approach is limited. Materials and Methods: Connect.Parkinson is a randomized comparative effectiveness study that compares usual care of individuals with Parkinson's disease in the community with usual care augmented by virtual house calls with a Parkinson's disease specialist from 1 of 18 centers nationally. Individuals in the intervention arm receive four virtual visits from a Parkinson's disease specialist over 1 year via secure, Web-based videoconferencing directly into their homes. All study activities, including recruitment, enrollment, and assessments, are conducted remotely. Here we report on interest, feasibility, and barriers to enrollment in this ongoing study. Results: During recruitment, 11,734 individuals visited the study's Web site, and 927 unique individuals submitted electronic interest forms. Two hundred ten individuals from 18 states enrolled in the study from March 2014 to June 2015, and 195 were randomized. Most participants were white (96%) and college educated (73%). Of the randomized participants, 73% had seen a Parkinson's disease specialist within the previous year. Conclusions: Among individuals with Parkinson's disease, national interest in receiving remote specialty care directly into the home is high. Remote enrollment in this care model is feasible but is likely affected by differential access to the Internet. PMID:26886406

Individuals with serious mental illnesses have high rates of comorbid physical health issues and have numerous barriers to addressing their health and health care needs. The present pilot study tested the feasibility of a modified form of the "Bridge" peer-health navigator intervention delivered in a usual care setting by agency personnel. The modifications concerned the use of an electronic personal health record with individuals experiencing with housing instability. Twenty participants were randomized to receive the intervention immediately or after 6 months. Health navigator contacts and use of personal health records were associated with improvements in health care and self-management. This pilot study demonstrated promising evidence for the feasibility of adding personal health record use to a peer-led intervention.

HIV prevalence among Chinese men who have sex with men has rapidly increased in recent years. In this randomized, controlled study, we tested the feasibility and efficacy of motivational interviewing to reduce high-risk sexual behaviors among this population in Changsha, China. Eighty men who have sex with men were randomly assigned to either the intervention group, in which participants received a three-session motivational interviewing intervention over 4 weeks, or the control group, in which participants received usual counseling from peer educators. High-risk behavior indicators and HIV knowledge level were evaluated at baseline and 3 months after the intervention. Motivational interviewing significantly improved consistent anal condom use. However, there was no significant change in consistent condom use for oral sex or in the number of sexual partners over time. HIV knowledge scores improved equally in both groups. This study demonstrated that an intervention using motivational interviewing is feasible and results in increased condom use during anal sex for Chinese men who have sex with men. However, further work must be done to increase the use of condoms during oral sexual encounters. © 2016 John Wiley & Sons Australia, Ltd.

Methods This was a randomized controlled study that integrated CHWs as part of the team leading diabetes group visits for low-income Hispanic adults (n = 50). Group visits met for 3 hours each month for a 6-month duration. Main measures included baseline and 6-month clinical outcomes (ie, A1C, lipids), concordance with 8 standard of care guidelines (ie, screens for cervical, breast, and colon cancer) from the US Preventive Task Force and American Diabetes Association, and participant acceptability. Results Compared to control participants, the intervention group resulted in significantly better clinical outcomes or guideline concordance for the following areas: target A1C levels, retinal eye exams, diabetes foot exams, mammograms, and urine microalbumin. Significantly more individuals in the control group gained weight, whereas a greater number of participants in the intervention group lost weight. Intervention participants found the group visits highly acceptable. Conclusions Integrating CHWs as part a comprehensive diabetes group visit program is a feasible and effective system-level intervention to improve glycemic control and achieve guideline concordance.

While exercise significantly reduces craving for cigarettes, the effect of exercise on self-initiation of quit attempts is less known. Therefore, this randomized pilot study explored the effect of starting an exercise program on self-initiated quit attempts, and also the feasibility and acceptability of a novel exercise intervention, high-intensity interval training (HIIT), as compared with a more traditional continuous aerobic (CA) exercise intervention. Participants smoked (≥5 cigarettes/d), were aged 18 to 40 years, and wanted to increase their exercise. Participants were randomized into 1 of 3 groups: HIIT, CA, and delayed control. All participants attended follow-up visits at weeks 4, 8, and 12. Outcomes included measures of feasibility (eg, visit attendance) and acceptability (eg, satisfaction), and also changes in smoking behavior (eg, quit attempts during follow-up) and proxies to quit attempts (eg, positive affect). Overall, there were no differences in terms of feasibility and acceptability between the HITT (n = 12) and CA (n = 9) groups. Based on both self-report and objective measurement, the exercise groups (HIIT and CA) increased their physical activity as compared with the delayed treatment group (n = 11). Compared with HIIT and delayed control, CA (n = 9) had significant favorable changes in positive affect (eg, at week 8, HIIT: +0.25 ± 2.21, delayed control: -5.11 ± 2.23, CA: +5.50 ± 2.23; P = 0.0153). These observations suggest that HIIT is as feasible and acceptable as CA, though CA may have a more favorable effect on proxies to quit attempts (eg, positive affect). Fully powered studies are needed to examine the effect of HIIT versus CA on quit attempts.

Cerebral oxygen desaturation during cardiac surgery has been associated with adverse perioperative outcomes. Before a large multicenter randomized controlled trial (RCT) on the impact of preventing desaturations on perioperative outcomes, the authors undertook a randomized prospective, parallel-arm, multicenter feasibility RCT to determine whether an intervention algorithm could prevent desaturations. Eight Canadian sites randomized 201 patients between April 2012 and October 2013. The primary outcome was the success rate of reversing cerebral desaturations below 10% relative to baseline in the intervention group. Anesthesiologists were blinded to the cerebral saturation values in the control group. Intensive care unit personnel were blinded to cerebral saturation values for both groups. Secondary outcomes included the area under the curve of cerebral desaturation load, enrolment rates, and a 30-day follow-up for adverse events. Cerebral desaturations occurred in 71 (70%) of the 102 intervention group patients and 56 (57%) of the 99 control group patients (P = 0.04). Reversal was successful in 69 (97%) of the intervention group patients. The mean cerebral desaturation load (SD) in the operating room was smaller for intervention group patients compared with control group patients (104 [217] %.min vs. 398 [869] %.min, mean difference, -294; 95% CI, -562 to -26; P = 0.03). This was also true in the intensive care unit (P = 0.02). There were no differences in adverse events between the groups. Study sites were successful in reversal of desaturation, patient recruitment, randomization, and follow-up in cardiac surgery, supporting the feasibility of conducting a large multicenter RCT.

Venous leg ulcers (VLUs) are typically painful and heal slowly. Compression therapy offers high healing rates; however, improvements are not usually sustained. Exercise is a low-cost, low-risk and effective strategy for improving physical and mental health. Little is known about the feasibility and efficacy of supervised exercise training used in combination with compression therapy patients with VLUs. To assess the feasibility of a 12-week supervised exercise programme as an adjunct therapy to compression in patients with VLUs. This was a two-centre, two-arm, parallel-group, randomized feasibility trial. Thirty-nine patients with venous ulcers were recruited and randomized 1 : 1 either to exercise (three sessions weekly) plus compression therapy or compression only. Progress/success criteria included exercise attendance rate, loss to follow-up and patient preference. Baseline assessments were repeated at 12 weeks, 6 months and 1 year, with healing rate and time, ulcer recurrence and infection incidents documented. Intervention and healthcare utilization costs were calculated. Qualitative data were collected to assess participants' experiences. Seventy-two per cent of the exercise group participants attended all scheduled exercise sessions. No serious adverse events and only two exercise-related adverse events (both increased ulcer discharge) were reported. Loss to follow-up was 5%. At 12 months, median ulcer healing time was lower in the exercise group (13 vs. 34·7 weeks). Mean National Health Service costs were £813·27 for the exercise and £2298·57 for the control group. The feasibility and acceptability of both the supervised exercise programme in conjunction with compression therapy and the study procedures is supported. © 2017 The Authors.

To assess the feasibility of the novel intervention, Ronnie Gardiner Rhythm and Music (RGRM™) Method compared to a control group for patients with Parkinson's disease (PD). Eighteen patients, mean age 68, participating in a disability study within a neurological rehabilitation centre, were randomly allocated to intervention group (n = 12) or control group (n = 6). Feasibility was assessed by comparing effects of the intervention on clinical outcome measures (primary outcome: mobility as assessed by two-dimensional motion analysis, secondary outcomes: mobility, cognition, quality of life, adherence, adverse events and eligibility). Univariable analyses showed no significant differences between groups following intervention. However, analyses suggested that patients in the intervention group improved more on mobility (p = 0.006), cognition and quality of life than patients in the control group. There were no adverse events and a high level of adherence to therapy was observed. In this disability study, the use of the RGRM™ Method showed promising results in the intervention group and the adherence level was high. Our results suggest that most assessments chosen are eligible to use in a larger randomized controlled study for patients with PD. The RGRM™ Method appeared to be a useful and safe method that showed promising results in both motor and cognitive functions as well as quality of life in patients with moderate PD. The RGRM™ Method can be used by physiotherapists, occupational, speech and music therapists in neurological rehabilitation. Most measurements were feasible except for Timed-Up-and-Go.

Previous studies on optimization of crew diets have not accounted for choice. A diet selection model with crew choice was developed. Scenario analyses were conducted to assess the feasibility and cost of certain crew preferences, such as preferences for numerous-desserts, high-salt, and high-acceptability foods. For comparison purposes, a no-choice and a random-choice scenario were considered. The model was found to be feasible in terms of food variety and overall costs. The numerous-desserts, high-acceptability, and random-choice scenarios all resulted in feasible solutions costing between 13.2 and 17.3 kg ESM/person-day. Only the high-sodium scenario yielded an infeasible solution. This occurred when the foods highest in salt content were selected for the crew-choice portion of the diet. This infeasibility can be avoided by limiting the total sodium content in the crew-choice portion of the diet. Cost savings were found by reducing food variety in scenarios where the preference bias strongly affected nutritional content.

Polypharmacy and adverse drug reactions are frequent and important among older people. Few clinical trials have evaluated systematic withdrawal of medications among older people. This small, open, study was conducted to determine the feasibility of a randomized controlled deprescribing trial. Ten volunteers living in the community (recruited by media advertising) and 25 volunteers living in residential aged-care facilities (RCFs) were randomized to intervention or control groups. The intervention was gradual withdrawal of one target medication. The primary outcome was the number of intervention participants in whom medication withdrawal could be achieved. Other outcomes measures were quality of life, medication adherence, sleep quality, and cognitive impairment. Participants were aged 80 ± 11 years and were taking 9 ± 2 medications. Fifteen participants commenced medication withdrawal and all ceased or reduced the dose of their target medication. Two subjects withdrew; one was referred for clinical review, and one participant declined further dose reductions. A randomized controlled trial of deprescribing was acceptable to participants. Recruitment in RCFs is feasible. Definitive trials of deprescribing are required.

Acute upper gastrointestinal bleeding (AUGIB) is the commonest reason for hospitalization with hemorrhage in the UK and the leading indication for transfusion of red blood cells (RBCs). Observational studies suggest an association between more liberal RBC transfusion and adverse patient outcomes, and a recent randomised trial reported increased further bleeding and mortality with a liberal transfusion policy. TRIGGER (Transfusion in Gastrointestinal Bleeding) is a pragmatic, cluster randomized trial which aims to evaluate the feasibility and safety of implementing a restrictive versus liberal RBC transfusion policy in adult patients admitted with AUGIB. The trial will take place in 6 UK hospitals, and each centre will be randomly allocated to a transfusion policy. Clinicians throughout each hospital will manage all eligible patients according to the transfusion policy for the 6-month trial recruitment period. In the restrictive centers, patients become eligible for RBC transfusion when their hemoglobin is <8 g/dL. In the liberal centers patients become eligible for transfusion once their hemoglobin is <10 g/dL. All clinicians will have the discretion to transfuse outside of the policy but will be asked to document the reasons for doing so. Feasibility outcome measures include protocol adherence, recruitment rate, and evidence of selection bias. Clinical outcome measures include further bleeding, mortality, thromboembolic events, and infections. Quality of life will be measured using the EuroQol EQ-5D at day 28, and the costs associated with hospitalization for AUGIB in the UK will be estimated. Consent will be sought from participants or their representatives according to patient capacity for use of routine hospital data and day 28 follow up. The study has ethical approval for conduct in England and Scotland. Results will be analysed according to a pre-defined statistical analysis plan and disseminated in peer reviewed publications to relevant stakeholders. The results of this study will inform the feasibility and design of a phase III randomized trial. Copyright © 2013 Elsevier Inc. All rights reserved.

A quantum random-number generator (QRNG) can produce true randomness by utilizing the inherent probabilistic nature of quantum mechanics. Recently, the spontaneous-emission quantum phase noise of the laser has been widely deployed for quantum random-number generation, due to its high rate, its low cost, and the feasibility of chip-scale integration. Here, we perform a comprehensive experimental study of a phase-noise-based QRNG with two independent lasers, each of which operates in either continuous-wave (CW) or pulsed mode. We implement the QRNG by operating the two lasers in three configurations, namely, CW + CW, CW + pulsed, and pulsed + pulsed, and demonstrate their trade-offs, strengths, and weaknesses.

Despite evidence of benefit for pharmacist involvement in chronic disease management, the provision of these services in community pharmacy has been suboptimal. The Promoting Action on Research Implementation in Health Services (PARiHS) framework suggests that for knowledge translation to be effective, there must be evidence of benefit, a context conducive to implementation, and facilitation to support uptake. We hypothesize that while the evidence and context components of this framework are satisfied, that uptake into practice has been insufficient because of a lack of facilitation. This protocol describes the rationale and methods of a feasibility study to test a facilitated pharmacy practice intervention based on the PARiHS framework, to assist community pharmacists in increasing the number of formal and documented medication management services completed for patients with diabetes, dyslipidemia, and hypertension. A cluster-randomized before-after design will compare ten pharmacies from within a single organization, with the unit of randomization being the pharmacy. Pharmacies will be randomized to facilitated intervention based on the PARiHS framework or usual practice. The Alberta Context Tool will be used to establish the context of practice in each pharmacy. Pharmacies randomized to the intervention will receive task-focused facilitation from an external facilitator, with the goal of developing alternative team processes to allow the greater provision of medication management services for patients with diabetes, hypertension, and dyslipidemia. The primary outcome will be a process evaluation of the needs of community pharmacies to provide more clinical services, the acceptability and uptake of modifications made, and the willingness of pharmacies to participate. Secondary outcomes will include the change in the number of formal and documented medication management services in the aforementioned chronic conditions provided 6 months before, versus after, the intervention between the two groups, and identification of feasible quantitative outcomes for evaluating the effect of the intervention on patient care outcomes. To date, the study has identified and enrolled the ten pharmacies required and initiated the intervention process. This study will be the first to examine the role of facilitation in pharmacy practice, with the goal of scalable and sustainable practice change. Clinicaltrials.gov identifier NCT02191111.

The development of adaptive treatment strategies (ATS) represents the next step in innovating conduct problems prevention programs within a juvenile diversion context. Toward this goal, we present the theoretical rationale, associated methods, and anticipated challenges for a feasibility pilot study in preparation for implementing a full-scale SMART (i.e., sequential, multiple assignment, randomized trial) for conduct problems prevention. The role of a SMART design in constructing ATS is presented. The SMART feasibility pilot study includes a sample of 100 youth (13-17 years of age) identified by law enforcement as early stage offenders and referred for precourt juvenile diversion programming. Prior data on the sample population detail a high level of ethnic diversity and approximately equal representations of both genders. Within the SMART, youth and their families are first randomly assigned to one of two different brief-type evidence-based prevention programs, featuring parent-focused behavioral management or youth-focused strengths-building components. Youth who do not respond sufficiently to brief first-stage programming will be randomly assigned a second time to either an extended parent- or youth-focused second-stage programming. Measures of proximal intervention response and measures of potential candidate tailoring variables for developing ATS within this sample are detailed. Results of the described pilot study will include information regarding feasibility and acceptability of the SMART design. This information will be used to refine a subsequent full-scale SMART. The use of a SMART to develop ATS for prevention will increase the efficiency and effectiveness of prevention programing for youth with developing conduct problems.

Objective. To assess the feasibility of a parent mentor model of intervention for early childhood obesity using positive deviance-based methods to inform the intervention. Methods. In this pilot, randomized clinical trial, parent-child dyads (age: 2-5) with children whose body mass index (BMI) was ≥95th percentile were randomized to parent mentor intervention or community health worker comparison. The child's height and weight were measured at baseline, after the six-month intervention, and six months after the intervention. Feasibility outcomes were recruitment, participation, and retention. The primary clinical outcome was BMI z-score change. Results. Sixty participants were enrolled, and forty-eight completed the six-month intervention. At baseline, the BMI z-score in the parent mentor group was 2.63 (SD = 0.65) and in the community health worker group it was 2.61 (SD = 0.89). For change in BMI z-score over time, there was no difference by randomization group at the end of the intervention: -0.02 (95% CI: -0.26, 0.22). At the end of the intervention, the BMI z-score for the parent mentor group was 2.48 (SD = 0.58) and for the community health worker group it was 2.45 (SD = 0.91), both reduced from baseline, p < 0.001. Conclusion. The model of a parent mentor clinical trial is feasible, and both randomized groups experienced small, sustained effects on adiposity in an obese, Hispanic population.

Rising rates of smartphone ownership highlight opportunities for improved mobile application usage in clinical trials. While current methods call for device provisioning, the "bring your own device" (BYOD) model permits participants to use personal phones allowing for improved patient engagement and lowered operational costs. However, more evidence is needed to demonstrate the BYOD model's feasibility in research settings. To assess if CentrosHealth, a mobile application designed to support trial compliance, produces different outcomes in medication adherence and application engagement when distributed through study-provisioned devices compared to the BYOD model. 87 participants were randomly selected to use the mobile application or no intervention for a 28-day pilot study at a 2:1 randomization ratio (2 intervention: 1 control) and asked to consume a twice-daily probiotic supplement. The application users were further randomized into two groups: receiving the application on a personal "BYOD" or study-provided smartphone. In-depth interviews were performed in a randomly-selected subset of the intervention group (five BYOD and five study-provided smartphone users). The BYOD subgroup showed significantly greater engagement than study-provided phone users, as shown by higher application use frequency and duration over the study period. The BYOD subgroup also demonstrated a significant effect of engagement on medication adherence for number of application sessions (unstandardized regression coefficient beta=0.0006, p=0.02) and time spent therein (beta=0.00001, p=0.03). Study-provided phone users showed higher initial adherence rates, but greater decline (5.7%) than BYOD users (0.9%) over the study period. In-depth interviews revealed that participants preferred the BYOD model over using study-provided devices. Results indicate that the BYOD model is feasible in health research settings and improves participant experience, calling for further BYOD model validity assessment. Although group differences in medication adherence decline were insignificant, the greater trend of decline in provisioned device users warrants further investigation to determine if trends reach significance over time. Significantly higher application engagement rates and effect of engagement on medication adherence in the BYOD subgroup similarly imply that greater application engagement may correlate to better medication adherence over time.

This study aimed to test the feasibility of implementing a psychoeducational intervention program for gynecological cancer patients. A single-blinded randomized controlled trial and mixed-method design were used. Study subjects were newly diagnosed gynecological cancer patients with surgery as the first-line treatment. They were randomly assigned to the intervention group, in which a psychoeducational intervention program based on a thematic counseling model was offered, or to the attention control group. Quantitative data on sexual functioning, quality of life, uncertainty, anxiety, depression and social support were collected at recruitment, post-operative and during the in-hospital period, and eight weeks after the operation. Participants in the intervention group and three nurses working in the clinical setting were invited to have semi-structured interviews. Of the 30 eligible subjects, 26 were successfully recruited into the study. Following the psychoeducational intervention program, there was significant improvement in the level of inconsistent information about the illness within the category of uncertainty among participants in the intervention group. In addition, trends towards improvement were demonstrated in quality of life, uncertainty, depression and perceived social support with the provision of the interventions. Qualitative data indicated the interventions were desired and appreciated by the participants, as well as being feasible and practical to implement in Hong Kong clinical settings. The findings suggest that it is feasible to deliver the psychoeducational intervention program and it may have beneficial effects in gynecological cancer patients. A full-scale study is warranted to confirm the results. Copyright © 2014 Elsevier Ltd. All rights reserved.

Current methods of dosing platinum-based chemotherapy are suboptimal. Potentially, taking lean body mass into account may help. To inform the design of a future study, we first examined the feasibility and acceptability of such an approach using dual-energy X-ray absorptiometry (DEXA) and explored aspects suggestive of over- and under-dosing. Patients with lung cancer offered platinum-based chemotherapy over 1 year were identified and, if eligible, invited to take part in a prospective feasibility study. Questionnaires examined acceptability of the DEXA scan and of a future study that randomized between traditional dosing and one adjusted according to body composition. Dose-limiting toxicity (DLT) and a lack of neutropenia explored potential over- and under-dosing, respectively. Of the 173 patients offered chemotherapy, 123 (71%) were ineligible, mostly because of failing entry criteria (84, 49%). Of the 50 approached, 18 (36%) participated, most receiving carboplatin, with 17 providing data. All found a DEXA scan acceptable; other assessments were fully completed, except nadir and pre-chemotherapy blood counts. Most (94%) were prepared to take part in a future study, although the additional hospital visits for a nadir blood count were unpopular with some. Five (29%) patients experienced six episodes of DLT which resulted in discontinuation (3), dose reduction (2) or change to a less toxic regimen (1). Nine (60%) patients experienced either no (2) or inconsistent (7) neutropenia. A randomized trial appears acceptable and feasible in patients receiving carboplatin. Adjustment of our entry criteria and avoiding a hospital visit for a nadir blood count should aid recruitment.

We report the rationale and design of a community PHARMacy-based prospective randomized controlled interdisciplinary study for ambulatory patients with Chronic Heart Failure (PHARM-CHF) and results of its pilot study. The pilot study randomized 50 patients to a pharmacy-based intervention or usual care for 12 months. It demonstrated the feasibility of the design and showed reduced systolic blood pressure in the intervention group as indicator for improved medication adherence. The main study will randomize patients ≥60 years on stable pharmacotherapy including at least one diuretic and a history of heart failure hospitalization within 12 months. The intervention group will receive a medication review at baseline followed by regular dose dispensing of the medication, counselling regarding medication use and symptoms of heart failure. The control patients are unknown to the pharmacy and receive usual care. The primary efficacy endpoint is medication adherence, pre-specified as a significant difference of the proportion of days covered between the intervention and control group within 365 days following randomization using pharmacy claims data for three CHF medications (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers, and mineralocorticoid receptor antagonists). The primary composite safety endpoint is days lost due to blindly adjudicated unplanned cardiovascular hospitalizations or death. Overall, 248 patients shall be randomized. The minimum follow-up is 12 months with an expected mean of 24 months. Based on the feasibility demonstrated in the pilot study, the randomized PHARM-CHF trial will test whether an interdisciplinary pharmacy-based intervention can safely improve medication adherence and will estimate the potential impact on clinical endpoints.

This feasibility study assessed the effects of an exercise plus group-based self-regulatory skills intervention on obese youths' physical activity, social cognitions, body composition and strength. Forty-three obese youth (male = 13, BMI > 95th percentile; 10-16 yrs) completed this 12-week intervention. Assessments were taken at baseline, week 6, 13 and 12 weeks post-intervention (week 24). Although no attention control group (i.e. exercise only) was included in this study, participants engaged in significantly more self-reported physical activity at weeks 13 and 24 as compared to baseline. Social cognitions, body composition and strength were also positively impacted suggesting this intervention technique may be feasible for treating obese adolescents.

This study aimed to test the feasibility of a psychosocially supportive writing intervention focused on finding balance for older adult bereaved family caregivers of advanced cancer patients. The Finding Balance Intervention (FBI) was tested for feasibility, acceptability and potential influence on increasing hope, coping and balance through a multi-method pilot study employing a randomized trial design with 19 older adults with an average age of 72 years. The intervention group received the FBI and a follow up visit from an RN-RA. The control group received the FBI at a second visit. The FBI, a theory-based intervention was developed from grounded theory qualitative data, applying Delphi methods to design a self-administered, psychosocially supportive, writing intervention for older adults who had lost a spouse after caregiving. Feasibility was assessed and specific modifications identified. The FBI was easy to use, acceptable and of benefit. The FBI offered validation of emotions and ways to discover new ideas to find balance, which may enable bereaved caregivers to move forward on a unique journey through grief. The treatment group showed a statistically significant increase in restoration-oriented coping and higher oscillation activity. The results suggest the FBI was easy to use, acceptable and of benefit. A full scale study, with specific modifications to the design, is needed to test the effectiveness of this innovative intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

For over 2 decades, oncology nurses at a regional comprehensive cancer center offered sliced oranges to patients during the reinfusion of autologous hematopoietic progenitor cells (HPCs) to relieve symptoms associated with the preservative dimethyl sulfoxide (DMSO). This randomized pilot study examined feasibility and efficacy of sliced orange intervention (OI), orange aromatherapy intervention (OAI), or deep breathing (control) to address unpleasant adverse effects during HPC infusion. Orange intervention sniffed or tasted a quartered orange, OAI sniffed orange aromatherapy, and control took deep breaths. Perceived "symptom intensity" for tickle/cough urge, nausea, retching, and perceived "relief" were measured on 0- to 10-point numerical scales. Sixty of 72 eligible patients consented to participate and were randomized to OI (n = 19), OAI (n = 23), or control (n = 18). Study personnel successfully administered study procedures. Over the course of 2 bags of cells infused, the OI group reported significantly greater relief with the intervention (P = .032). Among participants less than 90 kg, OI group reported significantly lower symptom intensity (P = .012). Results suggest a feasible protocol and potential efficacy of sliced oranges for treating symptoms associated with DMSO-preserved stem cells. Study procedures provide a tested protocol for future studies. Follow-up study is warranted to confirm these findings and evaluate other treatment options. Oranges offer a simple, noninvasive intervention for relieving symptoms associated with DMSO preservative during autologous HPC infusion.

Back pain is a leading contributor to disability, healthcare costs, and lost work. Family physicians are the most common first point of contact in the healthcare system for people with back pain, but physiotherapists (PTs) may be able to support the primary care team through evidence-based primary care. A cluster randomized trial is needed to determine the clinical, health system, and societal impact of a primary care model that integrates physiotherapists at the first visit for people with back pain. Prior to conducting a future fully powered cluster randomized trial, we need to demonstrate feasibility of the methods. Therefore, the purpose of this pilot study will be to: 1) Determine feasibility of patient recruitment, assessment procedures, and retention. 2) Determine the feasibility of training and implementation of a new PT-led primary care model for low back pain (LBP) 3) Explore the perspectives of patients and healthcare providers (HCPs) related to their experiences and attitudes towards the new service delivery model, barriers/facilitators to implementation, perceived satisfaction, perceived value, and impact on clinic processes and patient outcomes. This pilot cluster randomized controlled trial will enroll four sites and randomize them to implement a new PT-led primary care model for back pain or a usual physician-led primary care model. All adults booking a primary care visit for back pain will be invited to participate. Feasibility outcomes will include: recruitment and retention rates, completeness of assessment data, PT training participation and confidence after training, and PT treatment fidelity. Secondary outcomes will include the clinical, health system, cost, and process outcomes planned for the future fully powered cluster trial. Results will be analyzed and reported descriptively and qualitatively. To explore perspectives of both HCPs and patients, we will conduct semi-structured qualitative interviews with patients and focus groups with HCPs from participants in the PT-led primary care sites. If this pilot demonstrates feasibility, a fully powered trial will provide evidence that has the potential to transform primary care for back pain. The full trial will inform future service design, whether these models should be more widely implemented, and training agendas. ClinicalTrials.gov, NCT03320148 .

To evaluate the feasibility of executing a randomized controlled trial of progressive resistance training (PRT) in women with polycystic ovary syndrome (PCOS). Women with PCOS were randomized to an experimental (PRT) group or a no-exercise (usual care) control group. The PRT group was prescribed two supervised and two unsupervised (home-based) training sessions per week for 12 weeks. Feasibility outcomes included recruitment and attrition, adherence, adverse events, and completion of assessments. Secondary outcomes, collected pre and post intervention, included a range of pertinent physiological, functional and psychological measures. Fifteen participants were randomised into the PRT group (n = 8) or control group (n = 7); five women (n = 2 in PRT group and n = 3 in control group) withdrew from the study. The most successful recruitment sources were Facebook (40 %) and online advertisement (27 %), while least successful methods were referrals by clinicians, colleagues and flyers. In the PRT group, attendance to supervised sessions was higher (95 %; standard deviation ±6 %) compared to unsupervised sessions (51 %; standard deviation ±28 %). No adverse events were attributed to PRT. Change in menstrual cycle status was not significantly different between groups over time (p = 0.503). However, the PRT group significantly increased body weight (p = 0.01), BMI (p = 0.04), lean mass (p = 0.01), fat-free mass (p = 0.005) and lower body strength (p = 0.03), while reducing waist circumference (p = 0.03) and HbA1c (p = 0.033) versus the control group. The PRT group also significantly improved across several domains of disease-specific and general health-related quality of life, depression, anxiety and exercise self-efficacy. A randomized controlled trial of PRT in PCOS would be feasible, and this mode of exercise may elicit a therapeutic effect on clinically important outcomes in this cohort. The success of a large-scale trial required to confirm these findings would be contingent on addressing the feasibility hurdles identified in this study with respect to recruitment, attrition, compliance, and collection of standardized clinical data.

Background Patients, identified to be at risk for but who have never experienced a potentially lethal cardiac arrhythmia, have the option of receiving an implantable cardioverter defibrillator (ICD) as prophylaxis against sudden cardiac death - a primary prevention indication. In Canada, there is no clear framework to support patients’ decision-making for these devices. Decision support, using a decision aid, could moderate treatment-related uncertainty and prepare patients to make well-informed decisions. Patient decision aids provide information on treatment options, risks, and benefits, to help patients clarify their values for outcomes of treatment options. The objectives of this research are: 1) develop a decision aid, 2) evaluate the decision aid, and 3) determine the feasibility of conducting a trial. Methods/design A development panel comprised of the core investigative team, health service researchers, decision science experts, cardiovascular healthcare practitioners, and ICD patient representatives will collaborate to provide input on the content and format of the aid. To generate probabilities to include in the aid, we will synthesize primary prevention ICD evidence. To obtain anonymous input about the facts and content, we will employ a modified Delphi process. To evaluate the draft decision aid will invite ICD patients and their families (n = 30) to rate its acceptability. After we evaluate the aid, to determine the feasibility, we will conduct a feasibility pilot randomized controlled trial (RCT) in new ICD candidates (n = 80). Participants will be randomized to receive a decision aid prior to specialist consultation versus usual care. Results from the pilot RCT will determine the feasibility of research processes; inform sample size calculation, measure decision quality (knowledge, values, decision conflict) and the influence of health related quality of life on decision-making. Discussion Our study seeks to develop a decision aid, for patients offered their first ICD for prophylaxis against sudden cardiac death. This paper outlines the background and methods of a pilot randomized trial which will inform a larger multicenter trial. Ultimately, decision support prior to specialist consultation could enhance the decision-making process between patients, physicians, and families, associated with life-prolonging medical devices like the ICD.

Interventions promoting optimal infant and young child nutrition could prevent a fifth of under-5 deaths in countries with high mortality. Poor infant and young child feeding practices are widely documented in Kenya, with potential detrimental effects on child growth, health and survival. Effective strategies to improve these practices are needed. This study aims to pilot implementation of the Baby Friendly Community Initiative (BFCI), a global initiative aimed at promoting optimal infant and young child feeding practices, to determine its feasibility and effectiveness with regards to infant feeding practices, nutrition and health outcomes in a rural setting in Kenya. The study, employing a cluster-randomized trial design, will be conducted in rural Kenya. A total of 12 clusters, constituting community units within the government's Community Health Strategy, will be randomized, with half allocated to the intervention and the other half to the control arm. A total of 812 pregnant women and their respective children will be recruited into the study. The mother-child pairs will be followed up until the child is 6 months old. Recruitment will last approximately 1 year from January 2015, and the study will run for 3 years, from 2014 to 2016. The intervention will involve regular counseling and support of mothers by trained community health workers and health professionals on maternal, infant and young child nutrition. Regular assessment of knowledge, attitudes and practices on maternal, infant and young child nutrition will be done, coupled with assessment of nutritional status of the mother-child pairs and morbidity for the children. Statistical methods will include analysis of covariance, multinomial logistic regression and multilevel modeling. The study is funded by the NIH and USAID through the Program for Enhanced Research (PEER) Health. Findings from the study outlined in this protocol will inform potential feasibility and effectiveness of a community-based intervention aimed at promoting optimal breastfeeding and other infant feeding practices. The intervention, if proved feasible and effective, will inform policy and practice in Kenya and similar settings, particularly regarding implementation of the baby friendly community initiative.

Quasi-experiments have been infrequently used in the health sciences. Focusing on health systems implementation research, this article details key advantages of quasi-experiments and argues that they can complement (but not replace) randomized evaluations. Specifically, it may be possible to use a quasi-experiment to study the causal effect of an intervention that cannot feasibly be randomized or that would be unethical (e.g., because the intervention has become the standard of care) to test in a randomized controlled trial (RCT). In addition, because they usually take advantage of routinely collected data, quasi-experiments may be feasible when it is too costly (either financially or in terms of the required time) to carry out a RCT - an important advantage in research on health systems, which vary widely between settings. Nonetheless, we argue that RCTs will continue to be indispensable for implementation research because i) the assumptions needed to establish causality with a quasi-experiment are often unverifiable, ii) available data frequently do not allow for a rigorous quasi-experiment, and iii) randomized designs tend to lend themselves more to informing policy makers of causal effects prior to (or during) the full-scale rollout of an intervention than quasi-experiments.

This study aims to test the feasibility and preliminary efficacy of a couple-based communication intervention for advanced GI cancer delivered via videoconference. Thirty-two couples were randomly assigned to either couples communication skills training (CCST) or an education comparison intervention, both delivered via videoconference. Participation was limited to couples who reported communication difficulties at screening. Patients and partners completed measures of relationship functioning and individual functioning at baseline and post-intervention. Eighty-eight percent of randomized dyads completed all six sessions and reported high levels of satisfaction with the intervention. Between-group effect sizes suggested that the CCST intervention led to improvements in relationship satisfaction for patients and partners and to improvements in intimacy and communication for patients. A couples-based communication intervention delivered via videoconference is feasible and acceptable in the context of advanced cancer. Preliminary findings suggest that the intervention shows promise in contributing to enhanced relationship functioning. Copyright © 2016 John Wiley & Sons, Ltd.

Objectives. To assess the feasibility of treating musculoskeletal pain in the lower back and/or lower extremities in persons with Parkinson's disease (PD) with cranial electrotherapy stimulation (CES). Design. Randomized, controlled, double-blind trial. Setting. Veterans Affairs Medical Center, Community. Participants. Nineteen persons with PD and pain in the lower back and/or lower extremities. Thirteen provided daily pain rating data. Intervention. Of the thirteen participants who provided daily pain data, 6 were randomly provided with active CES devices and 7 with sham devices to use at home 40 minutes per day for six weeks. They recorded their pain ratings on a 0-to-10 scale immediately before and after each session. Main Outcome Measure. Average daily change in pain intensity. Results. Persons receiving active CES had, on average, a 1.14-point decrease in pain compared with a 0.23-point decrease for those receiving sham CES (Wilcoxon Z = −2.20, P = .028). Conclusion. Use of CES at home by persons with PD is feasible and may be somewhat helpful in decreasing pain. A larger study is needed to determine the characteristics of persons who may experience meaningful pain reduction with CES. Guidelines for future studies are provided. PMID:20976091

Background Raising a child with type 1 diabetes (T1D) means combining the demands of the disease management with everyday parenting, which is associated with increased levels of distress. A Web-based patient portal, Sugarsquare, was developed to support parents, by providing online parent-professional communication, online peer support and online disease information. Objective The first aim of this study was to assess the feasibility of conducting a multicenter, randomized controlled trial in Dutch parents of a child with T1D. The second aim was to assess the feasibility of implementing Sugarsquare in clinical practice. Methods The parents of 105 children (N=105) with T1D below the age of 13 participated in a 6-month multicenter randomized controlled feasibility trial. They were randomly assigned to an experimental (n=54, usual care and Sugarsquare) or a control group (n=51, usual care). Attrition rates and user statistics were gathered to evaluate feasibility of the trial and implementation. To determine potential efficacy, the parenting stress index (PSI-SF) was assessed at baseline (T0) and after 6 months (T1). Results Of a potential population of parents of 445 children, 189 were willing to participate (enrollment refusal=57.5%, n=256), 142 filled in the baseline questionnaire (baseline attrition rate=25%, n=47), and 105 also filled in the questionnaire at T1 (post randomization attrition rate during follow-up=26%, n=32). As such, 24% of the potential population participated. Analysis in the experimental group (n=54) revealed a total of 32 (59%) unique users, divided into 12 (38%) frequent users, 9 (28%) incidental users, and 11 (34%) low-frequent users. Of the total of 44 professionals, 34 (77%) logged in, and 32 (73%) logged in repeatedly. Analysis of the user statistics in the experimental group further showed high practicability and integration in all users, moderate acceptability and demand in parents, and high acceptability and demand in health care professionals. Baseline parenting stress index scores were related to the parents’ frequency of logging on (ρ=.282, P=.03) and page-views (ρ=.304, P=.01). No significant differences in change in parenting stress between experimental and control group were found (F3,101=.49, P=.49). Conclusions The trial can be considered feasible, considering the average enrollment refusal rate, baseline attrition rate and postrandomization attrition rate, compared to other eHealth studies, although lower than hypothesized. Implementing Sugarsquare in clinical practice was partly feasible, given moderate demand and acceptability in parent users and lack of potential efficacy. Parents who reported higher levels of parenting stress used Sugarsquare more often than other parents, although Sugarsquare did not reduce parenting stress. These results indicate that Web-based interventions are a suitable way of providing parents of children with T1D with additional support. Future studies should determine how Sugarsquare could reduce parenting stress, for instance by adding targeted interventions. Factors potentially contributing to successful implementation are suggested.

Limited data suggest that crime may have a devastating impact on older people. Although identification and treatment may be beneficial, no well-designed studies have investigated the prevalence of mental disorder and the potential benefits of individual manualized CBT in older victims of crime. To identify mental health problems in older victims of common crime, provide preliminary data on its prevalence, and conduct a feasibility randomized controlled trial (RCT) using mixed methods. Older victims, identified through police teams, were screened for symptoms of anxiety, depression or post-traumatic stress disorder (PTSD) one (n = 581) and 3 months (n = 486) after experiencing a crime. Screen positive participants were offered diagnostic interviews. Of these, 26 participants with DSM-IV diagnoses agreed to be randomized to Treatment As Usual (TAU) or TAU plus our manualized CBT informed Victim Improvement Package (VIP). The latter provided feedback on the VIP. Recruitment, assessment and intervention are feasible and acceptable. At 3 months 120/486 screened as cases, 33 had DSM-IV criteria for a psychiatric disorder; 26 agreed to be randomized to a pilot trial. There were trends in favour of the VIP in all measures except PTSD at 6 months post crime. This feasibility RCT is the first step towards improving the lives of older victims of common crime. Without intervention, distress at 3 and 6 months after a crime remains high. However, the well-received VIP appeared promising for depressive and anxiety symptoms, but possibly not posttraumatic stress disorder.

Most existing evidence-based sexual health interventions focus on individual-level behavior, even though there is substantial evidence that highlights the influential role of social environments in shaping adolescents' behaviors and reproductive health outcomes. We developed Yo Puedo, a combined conditional cash transfer and life skills intervention for youth to promote educational attainment, job training, and reproductive health wellness that we then evaluated for feasibility among 162 youth aged 16-21 years in a predominantly Latino community in San Francisco, CA. The intervention targeted youth's social networks and involved recruitment and randomization of small social network clusters. In this paper we describe the design of the feasibility study and report participants' baseline characteristics. Furthermore, we examined the sample and design implications of recruiting social network clusters as the unit of randomization. Baseline data provide evidence that we successfully enrolled high risk youth using a social network recruitment approach in community and school-based settings. Nearly all participants (95%) were high risk for adverse educational and reproductive health outcomes based on multiple measures of low socioeconomic status (81%) and/or reported high risk behaviors (e.g., gang affiliation, past pregnancy, recent unprotected sex, frequent substance use; 62%). We achieved variability in the study sample through heterogeneity in recruitment of the index participants, whereas the individuals within the small social networks of close friends demonstrated substantial homogeneity across sociodemographic and risk profile characteristics. Social networks recruitment was feasible and yielded a sample of high risk youth willing to enroll in a randomized study to evaluate a novel sexual health intervention.

Frailty can be defined as a medical syndrome with multiple causes and contributors, characterized by diminished strength and endurance and reduced physiological function that increases the vulnerability to develop functional dependency and/or death. Studies have shown that the most commonly studied exercise protocol for frail older adults is the multimodal training. Interactive video games (IVGs) involve tasks in virtual environments that combine physical and cognitive demands in an attractive and challenging way. The aim of this study will be to evaluate the feasibility, safety, acceptability, and functional outcomes of playing Nintendo Wii Fit Plus TM (NWFP) for frail older adults. The study is a randomized controlled, parallel group, feasibility trial. Participants will be randomly assigned to the experimental group (EG) and control group (CG). The EG will participate in 14 training sessions, each lasting 50 min, twice a week. In each training session, the participants will play five games, with three attempts at each game. The first attempt will be performed with the assistance of a physical therapist to correct the movements and posture of the patients and subsequent attempts will be performed independently. Scores achieved in the games will be recorded. The participants will be evaluated by a blinded physical therapist at three moments: before and after intervention and 30 days after the end of the intervention (follow-up). We will assess the feasibility, acceptability, safety, and clinical outcomes (postural control, gait, cognition, quality of life, mood, and fear of falling). Due to the deficiencies in multiple systems, studies have shown that multimodal interventions including motor-cognitive stimulation can improve the mobility of frail elderly adults. IVGs, among them the NWFP, are considered as a multimodal motor-cognitive intervention that can potentially improve motor and cognitive functions in the frail elderly. However, there is still no evidence in the literature that proves the feasibility, safety, acceptability, and functional outcomes of this intervention in frail elderly individuals.

To investigate the feasibility and potential efficacy of the Nintendo Wii™ for balance rehabilitation after stroke. Phase II, single-blind, randomized controlled trial. Inpatient rehabilitation facility. Thirty adults (mean age 63.6 (14.7) years) undergoing inpatient rehabilitation who were less than three months post-stroke and able to stand unsupported. Participants were allocated to a Balance Group, using the 'Wii Fit Plus' in standing, or Upper Limb Group, using the 'Wii Sports/Sports Resort' in sitting. Both groups undertook three 45 minute sessions per week over two to four weeks in addition to standard care. The primary focus was feasibility, addressed by recruitment, retention, adherence, acceptability and safety. Efficacy was evaluated by balance, mobility and upper limb outcomes. Twenty-one percent of individuals screened were recruited and 86% (n = 30) of eligible people agreed to participate. Study retention and session adherence was 90% and > 99%, respectively, at two weeks; dropping to 70% and 87% at four weeks due to early discharge. All participants reported enjoying the sessions and most felt they were beneficial. No major adverse events occurred. Wii use by the Balance Group was associated with trends for improved balance, with significantly greater improvement in outcomes including the Step Test and Wii Balance Board-derived centre of pressure scores. The Upper Limb Group had larger, non-significant changes in arm function. A Wii-based approach appears feasible and promising for post-stroke balance rehabilitation. A larger randomized controlled trial is recommended to further investigate efficacy. © The Author(s) 2014.

Acute heart failure (AHF) is a frequent reason for hospitalization worldwide and effective treatment options are limited. It is known that AHF is a condition characterized by impaired vasorelaxation, together with reduced nitric oxide (NO) bioavailability, an endogenous vasodilatory compound. Supplementation of inorganic sodium nitrate (NaNO 3 ) is an indirect dietary source of NO, through bioconversion. It is proposed that oral sodium nitrate will favorably affect levels of circulating NO precursors (nitrate and nitrite) in AHF patients, resulting in reduced systemic vascular resistance, without significant hypotension. We propose a single center, randomized, double-blind, placebo-controlled pilot trial, evaluating the feasibility of sodium nitrate as a treatment for AHF. The primary hypothesis that sodium nitrate treatment will result in increased systemic levels of nitric oxide pre-cursors (nitrate and nitrite) in plasma, in parallel with improved vasorelaxation, as assessed by non-invasively derived systemic vascular resistance index. Additional surrogate measures relevant to the known pathophysiology of AHF will be obtained in order to assess clinical effect on dyspnea and renal function. The results of this study will provide evidence of the feasibility of this novel approach and will be of interest to the heart failure community. This trial may inform a larger study.

Background We launched the Boston University Pregnancy Study Online (PRESTO) to assess the feasibility of carrying out an internet-based preconception cohort study in the U.S. and Canada. Methods We recruited female participants age 21–45 and their male partners through internet advertisements, word of mouth, and flyers. Female participants were randomized with 50% probability to receive a subscription to FertilityFriend.com (FF), a web-based program that collects real-time data on menstrual characteristics. We compared recruitment methods within PRESTO, assessed the cost-efficiency of PRESTO relative to its Danish counterpart (Snart-Gravid), and validated retrospectively-reported date of last menstrual period (LMP) against FF data. Results After 99 weeks of recruitment (2013–2015), 2,421 women enrolled; 1,384 (57%) invited their male partners to participate, of whom 693 (50%) enrolled. Baseline characteristics were balanced across randomization groups. Cohort retention was similar among those randomized vs. not randomized to FF (84% vs. 81%). At study enrollment, 56%, 22%, and 22% couples had been trying to conceive for <3, 3–5, and ≥6 months, respectively. The cost per subject enrolled was $146 (2013 $US), which was similar to our companion Danish study and half that of a traditional cohort study. Among FF users who conceived, >97% reported their LMP on the PRESTO questionnaire within 1 day of the LMP recorded via FF. Conclusions Use of the internet as a method of recruitment and follow-up in a North American preconception cohort study was feasible and cost-effective. PMID:26111445

Although depression is a major contributor to the global burden of disease, services remain scarce in many low- and middle-income countries. In Vietnam, depression services are limited, and the government has recently prioritized primary care and community-based service integration. We conducted a pilot study in 2 districts of Hanoi to test the feasibility of (a) introducing a supported self-management (SSM) intervention for adult depression in primary care in Vietnam, and (b) conducting a randomized controlled trial (RCT) to test the effectiveness of the intervention. We conducted focus groups with providers (n = 16) and community members (n = 32) to assess the appropriateness of an Antidepressant Skills Workbook for use in Vietnam. We trained providers (n = 23) to screen patients using the Self-Reporting Questionnaire-20 (SRQ-20) depression scale and to deliver SSM for a 2-month period. A total of 71 patients were eligible to participate in the study, with depression (SRQ-20) and disability (World Health Organization Disability Assessment Schedule 2.0) scores assessed at baseline and 1 and 2 months. Study results demonstrate the feasibility of conducting a full RCT in Vietnam and suggest that SSM is an appropriate care model for the Vietnamese context. There was a statistically significant decrease in depression symptoms on the SRQ-20 and in functional disability in all domains for the World Health Organization Disability Assessment Schedule 2.). Feasibility study results suggested that a full RCT was warranted. An unanticipated outcome of the study was the uptake of the model by the Ministry of Labor, Invalids, and Social Affairs in 2 additional provinces.

The usefulness of landline random digit dialing (RDD) in epidemiologic studies is threatened by the rapid increase in households with only cellular telephone service. This study assessed the feasibility of including cellular telephone numbers in RDD and differences between young adults with landline telephones and those with only cellular telephones. Between 2008 and 2009, a total of 9,023 cellular telephone numbers were called and 43.8% were successfully screened; 248 men and 249 women who resided in 3 Washington State counties, were 20-44 years of age, and used only cellular telephones were interviewed. They were compared with 332 men and 526 women with landline telephones interviewed as controls for 2 case-control studies conducted in parallel with cellular telephone interviewing. Cellular-only users were more likely to be college educated and less likely to have fathered/birthed a child than were their landline counterparts. Male cellular-only users were less likely to be obese and more likely to exercise, to be Hispanic, and to have lower incomes, while female cellular-only users were more likely to be single than landline respondents. Including cellular telephone numbers in RDD is feasible and should be incorporated into epidemiologic studies that rely on this method to ascertain subjects, although low screening rates could hamper the representativeness of such a sample.
A feasibility study of valerian extract for sleep disturbance in person with arthritis.
Taibi, Diana M; Bourguignon, Cheryl; Gill Taylor, Ann

To present a pilot study of valerian to explore issues of feasibility and efficacy in studies of sedative herbs for arthritis-related sleep disturbance. Fifteen persons with arthritis and mild sleep disturbance were randomized to receive 600 mg valerian (Valeriana officinalis, n = 7) or placebo (n = 8) for five nights. Protocol adherence (dosing and data collection) was high. Allocation concealment was successful using a novel approach for matching the placebo on the distinctive odor of valerian. Nonsignificant differences between the groups were found on all sleep outcomes, measured by daily diaries and wrist actigraphy. The study methods were feasible, except for recruitment issues (addressed in the discussion), and may guide the testing of other sedative herbs for persons with arthritis. Although efficacy outcomes were inconclusive due to the small sample size of this study, recent evidence from larger trials of valerian also does not support its efficacy.

Ventilator-associated pneumonia (VAP) is a prevalent and costly nosocomial infection related to instrumentation of the airway with an endotracheal tube (ETT), enabling microaspiration of contaminated secretions. Modification of the ETT design to reduce microaspiration and/or biofilm formation may play an important role in VAP prevention. However, there is insufficient evidence to provide strong recommendations regarding the use of modified ETT and unaddressed safety concerns. We performed a pilot randomized controlled trial comparing two modified ETTs designed specifically to prevent VAP, with the standard ETT, to test the feasibility of and inform planning for a large, pivotal, randomized trial. This study was conducted with institutional review board approval under exception from informed consent. We randomized in a blinded fashion patients undergoing emergency endotracheal intubation both out of and in hospital to receive one of three different ETT types: (1) a polyurethane-cuffed tube (PUC-ETT), (2) a polyurethane-cuffed tube equipped with a port for continuous aspiration of subglottic secretions (PUC-CASS-ETT), or a (3) standard polyvinylchloride-cuffed tube (PVC-ETT). In addition to investigating feasibility and safety, the study coprimary end points were tracheal bacterial colonization reaching a cfu count >10(6) cfu per milliliter and the incidence of invasively diagnosed VAP. A total of 102 subjects were randomized and met the eligibility criteria. Randomization procedures performed well and integrity of blinding at randomization was maintained. The majority of intubations occurred in the hospital setting (n = 77), and the remainder occurred out of hospital (n = 25). Compared with the PVC-ETT, there were no significant differences in tracheal colonization for PUC-ETT (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.31-3.09) or for PUC-CASS-ETT (OR, 1.26; 95% CI, 0.42-3.76). There were no differences in the risk of invasively diagnosed VAP (OR, 1.14; 95% CI, 0.21-6.08 for PUC-ETT; OR, 1.47; 95% CI, 0.30-7.10 for PUC-CASS-ETT), or of clinically diagnosed VAP by either clinical signs or chest radiograph criteria. We did not observe unexpected or serious adverse events related to the devices. A randomized trial of ETTs inserted during emergency intubation for the prevention of VAP is feasible and did not appear to carry heightened safety concerns. These preliminary data did not suggest different patterns of tracheal colonization or occurrence of VAP among the study groups. Clinical trial registered with www.clinicaltrials.gov (NCT01744483).

Pharmacological therapy is only partially effective in preventing or treating chemotherapy induced nausea and vomiting (CINV). Therefore, exploring the complementary role of non-pharmacological approaches used in addition to pharmacological agents is important. Nevasic uses specially constructed audio signals hypothesized to generate an antiemetic reaction. The aim of this study was to examine the feasibility of conducting a randomized controlled trial (RCT) to evaluate the effectiveness of Nevasic to control CINV. A mixed methods design incorporating an RCT and focus group interviews. For the RCT, female breast cancer patients were randomized to receive either Nevasic plus usual care, music plus usual care, or usual care only. Data were analysed using descriptive statistics and linear mixed-effects models. Five focus group interviews were conducted to obtain participants' views regarding the acceptability of the interventions in the trial. 99 participants were recruited to the RCT and 15 participated in focus group interviews. Recruitment targets were achieved. Issues of Nevasic acceptability were highlighted as weaknesses of the program. This study did not detect any evidence for the effectiveness of Nevasic; however, the results showed statistically significant less use of anti-emetics (p = 0.003) and borderline non-significant improvement in quality of life (p = 0.06). Conducting a non-pharmacological intervention using such an audio program is feasible, although difficulties and limitations exist with its use. Further studies are required to investigate the effectiveness of Nevasic from perspectives such as anti-emetic use, as well as its overall effect on the levels of nausea and vomiting.

This study was conducted to assess the feasibility, acceptability, and changes in knowledge among cancer patients assigned to receive a 160-page book on experimental cancer therapies and clinical trials. We enrolled 20 patients with cancer who had never participated in a clinical trial and randomly assigned them to receive the book either during week 1 or week 4 of the study. We collected baseline patient demographic and cancer-related information as well as knowledge about cancer clinical trials at week 0. Follow-up surveys were administered at weeks 3 and 6 for both study groups. Comparisons were made within and between groups randomized to receive the book early (at week 1) to those who received it later (at week 4). One hundred percent of data were captured in both groups at baseline, which decreased to 77.8% by week 6. The vast majority of participants found the book moderately or very useful (89% in the Early Group at week 3 and 95.5% in the Late Group at week 6). Within group pairwise comparisons found significant difference between baseline and week 6 in content-specific knowledge scores among participants in the Late Group [79% versus 92.1%, p = 0.01). Global knowledge scores increased significantly for variables reflecting knowledge that promotes decisions to participate in clinical trials. Providing published reading material to patients with cancer is both feasible and acceptable. Offering information to patients about cancer clinical trials, using a book designed for patients with cancer may influence knowledge related to decision to participate in clinical trials.

OBJECTIVE The development of adaptive treatment strategies (ATS) represents the next step in innovating conduct problems prevention programs within a juvenile diversion context. Towards this goal, we present the theoretical rationale, associated methods, and anticipated challenges for a feasibility pilot study in preparation for implementing a full-scale SMART (i.e., sequential, multiple assignment, randomized trial) for conduct problems prevention. The role of a SMART design in constructing ATS is presented. METHOD The SMART feasibility pilot study includes a sample of 100 youth (13–17 years of age) identified by law enforcement as early stage offenders and referred for pre-court juvenile diversion programming. Prior data on the sample population detail a high level of ethnic diversity and approximately equal representations of both genders. Within the SMART, youth and their families are first randomly assigned to one of two different brief-type evidence-based prevention programs, featuring parent-focused behavioral management or youth-focused strengths-building components. Youth who do not respond sufficiently to brief first-stage programming will be randomly assigned a second time to either an extended parent- or youth-focused second-stage programming. Measures of proximal intervention response and measures of potential candidate tailoring variables for developing ATS within this sample are detailed. RESULTS Results of the described pilot study will include information regarding feasibility and acceptability of the SMART design. This information will be used to refine a subsequent full-scale SMART. CONCLUSIONS The use of a SMART to develop ATS for prevention will increase the efficiency and effectiveness of prevention programing for youth with developing conduct problems. PMID:25256135

Recent animal studies demonstrate that vagus nerve stimulation (VNS) paired with movement induces movement-specific plasticity in motor cortex and improves forelimb function after stroke. We conducted a randomized controlled clinical pilot study of VNS paired with rehabilitation on upper-limb function after ischemic stroke. Twenty-one participants with ischemic stroke >6 months before and moderate to severe upper-limb impairment were randomized to VNS plus rehabilitation or rehabilitation alone. Rehabilitation consisted of three 2-hour sessions per week for 6 weeks, each involving >400 movement trials. In the VNS group, movements were paired with 0.5-second VNS. The primary objective was to assess safety and feasibility. Secondary end points included change in upper-limb measures (including the Fugl-Meyer Assessment-Upper Extremity). Nine participants were randomized to VNS plus rehabilitation and 11 to rehabilitation alone. There were no serious adverse device effects. One patient had transient vocal cord palsy and dysphagia after implantation. Five had minor adverse device effects including nausea and taste disturbance on the evening of therapy. In the intention-to-treat analysis, the change in Fugl-Meyer Assessment-Upper Extremity scores was not significantly different (between-group difference, 5.7 points; 95% confidence interval, -0.4 to 11.8). In the per-protocol analysis, there was a significant difference in change in Fugl-Meyer Assessment-Upper Extremity score (between-group difference, 6.5 points; 95% confidence interval, 0.4 to 12.6). This study suggests that VNS paired with rehabilitation is feasible and has not raised safety concerns. Additional studies of VNS in adults with chronic stroke will now be performed.

Background and Purpose— Recent animal studies demonstrate that vagus nerve stimulation (VNS) paired with movement induces movement-specific plasticity in motor cortex and improves forelimb function after stroke. We conducted a randomized controlled clinical pilot study of VNS paired with rehabilitation on upper-limb function after ischemic stroke. Methods— Twenty-one participants with ischemic stroke >6 months before and moderate to severe upper-limb impairment were randomized to VNS plus rehabilitation or rehabilitation alone. Rehabilitation consisted of three 2-hour sessions per week for 6 weeks, each involving >400 movement trials. In the VNS group, movements were paired with 0.5-second VNS. The primary objective was to assess safety and feasibility. Secondary end points included change in upper-limb measures (including the Fugl–Meyer Assessment-Upper Extremity). Results— Nine participants were randomized to VNS plus rehabilitation and 11 to rehabilitation alone. There were no serious adverse device effects. One patient had transient vocal cord palsy and dysphagia after implantation. Five had minor adverse device effects including nausea and taste disturbance on the evening of therapy. In the intention-to-treat analysis, the change in Fugl–Meyer Assessment-Upper Extremity scores was not significantly different (between-group difference, 5.7 points; 95% confidence interval, −0.4 to 11.8). In the per-protocol analysis, there was a significant difference in change in Fugl–Meyer Assessment-Upper Extremity score (between-group difference, 6.5 points; 95% confidence interval, 0.4 to 12.6). Conclusions— This study suggests that VNS paired with rehabilitation is feasible and has not raised safety concerns. Additional studies of VNS in adults with chronic stroke will now be performed.

To examine the feasibility and acceptability of a PICU Soothing intervention using touch, reading, and music. Nonblinded, pilot randomized controlled trial. The PICU and medical-surgical wards of one Canadian pediatric hospital. Twenty PICU patients age 2-14 years old and their parents, randomized to an intervention group (n = 10) or control group (n = 10). PICU Soothing consisted of: 1) parental comforting (touch and reading), followed by 2) a quiet period with music via soft headbands, administered once daily throughout hospitalization. Acceptability and feasibility of the intervention and methods were assessed via participation rates, observation, measurement completion rates, semistructured interviews, and telephone calls. Psychological well-being was assessed using measures of distress, sleep, and child and parent anxiety in the PICU, on the wards and 3 months post discharge. Forty-four percent of parents agreed to participate. Seventy percent and 100% of intervention group parents responded positively to comforting and music, respectively. Most intervention group parents (70%) and all nurses felt children responded positively. All nurses found the intervention acceptable and feasible. Measurement completion rates ranged from 70% to 100%. Pilot data suggested lower intervention group child and parent anxiety after transfer to hospital wards. PICU Soothing is acceptable and feasible to conduct. Results support the implementation of a full-scale randomized controlled trial to evaluate intervention effectiveness.

The present study investigated the feasibility, acceptance and efficacy of a newly developed cognitive behavioral program for smoking cessation/reduction ('Rethink your Smoking' program, RSP) in inpatients with substance use disorder (SUD). One hundred ninety-nine inpatients with SUD were randomly assigned to either the RSP (n = 101) or a minimal intervention (MI) program (n = 98). In addition, participants were offered optional nicotine replacement therapy. Data from a group of patients with SUD without any intervention (control group, n = 78) were included in the analyses for comparison. Assessments were performed at admission, discharge and follow-up after 3 and 6 months. RSP proved to be feasible and was well accepted by participants. Patients in both interventions showed lower scores for physical nicotine dependence and number of cigarettes smoked per day and higher scores for various motivational parameters at discharge and 3 months later. Both interventions were superior to no intervention, but no differences were found between the RSP and MI. A smoking cessation/reduction program is feasible for substance-dependent in-patients undergoing detoxification. Although the RSP appears to be effective in terms of harm reduction in in-patients with SUD, more cost- and time-efficient programs might also be suitable for this population. © 2016 S.

Pain is a clinical hallmark of sickle cell disease (SCD), and is rarely optimally managed. Cognitive-behavioral therapy (CBT) for pain has been effectively delivered through the Internet in other pediatric populations. We tested feasibility and acceptability of an Internet-delivered CBT intervention in 25 adolescents with SCD (64% female, mean age=14.8 y) and their parents randomized to Internet CBT (n=15) or Internet Pain Education (n=10). Participants completed pretreatment/posttreatment measures. Eight dyads completed semistructured interviews to evaluate treatment acceptability. Feasibility indicators included recruitment and participation rates, engagement and adherence to intervention, and completion of outcome measures. In total, 87 referrals were received from 9 study sites; our recruitment rate was 60% from those families approached for screening. Among participants, high levels of initial intervention engagement (>90%), and adherence (>70%) were demonstrated. Most participants completed posttreatment outcome and diary measures (>75%). Retention at posttreatment was 80%. High treatment acceptability was reported in interviews. Our findings suggest that Internet-delivered CBT for SCD pain is feasible and acceptable to adolescents with SCD and their parents. Engagement and adherence were good. Next steps are to modify recruitment plans to enhance enrollment and determine efficacy of Internet CBT for SCD pain in a large multisite randomized controlled trial.

Although conventional laparoscopic and hand-assisted laparoscopic surgery for colorectal cancer is widely used today, there remain many technical challenges especially for right colon cancer in obese patients. Herein, we develop a novel hand-assisted laparoscopic surgery (HALS) with complete mesocolic excision (CME), D3 lymphadenectomy, and a total "no-touch" isolation technique (HALS-CME) in right hemicolectomy to overcome these issues. According to previous clinic practice, this novel procedure is not only feasible and safe but has several technical merits. However, the feasibility, short-term minimally invasive virtues, long-term oncological superiority, and potential total "no-touch" isolation technique benefits of HALS-CME should be confirmed by a prospective randomized controlled trial. This is a single-center, open-label, noninferiority, randomized controlled trial. Eligible participants will be randomly assigned to the HALS-CME group or to the laparoscopic surgery with CME, D3 lymphadenectomy, and total "no-touch" isolation technique (LAP-CME) group, or to conventional laparoscopic surgery with CME and D3 lymphadenectomy (cLAP) group at a 1:1:1 ratio using a centralized randomization list. Primary endpoints include safety, efficacy, and being oncologically clear, and 3-year disease-free, progression-free, and overall survival. Second endpoints include operative outcomes (operation time, blood loss, and incision length), pathologic evaluation (grading the plane of surgery, length of proximal and distal resection margins, distance between the tumor and the central arterial high tie, distance between the nearest bowel wall and the same high tie, area of mesentery resected, width of the chain of lymph-adipose tissue, length of the central lymph-adipose chain, number of harvested lymph nodes), and postoperative outcomes (pain intensity, postoperative inflammatory and immune responses, postoperative recovery). This trial will provide valuable clinical evidence for the feasibility, safety, and potential total "no-touch" isolation technique benefits of HALS-CME for right hemicolectomy. The hypothesis is that HALS-CME is feasible for the radical D3 resection of right colon cancer and offers short-term safety and long-term oncological superiority compared with conventional laparoscopic surgery.

BACKGROUND Randomized controlled trials (RCTs) in pediatric venous thromboembolism (VTE) treatment have been challenged by unsubstantiated design assumptions and/or poor accrual. Pilot/feasibility (P/F) studies are critical to future RCT success. METHODS Kids-DOTT is a multicenter RCT investigating non-inferiority of a 6-week (shortened) vs. 3-month (conventional) duration of anticoagulation in patients <21 years old with provoked venous thrombosis. Primary efficacy and safety endpoints are symptomatic recurrent VTE at 1 year and anticoagulant-related, clinically-relevant bleeding. In the P/F phase, 100 participants were enrolled in an open, blinded endpoint, parallel-cohort RCT design. RESULTS No eligibility violations or randomization errors occurred. Of enrolled patients, 69% were randomized, 3% missed the randomization window, and 28% were followed in pre-specified observational cohorts for completely occlusive thrombosis or persistent antiphospholipid antibodies. Retention at 1 year was 82%. Inter-observer agreement between local vs. blinded central determination of venous occlusion by imaging at 6 weeks post-diagnosis was strong (κ-statistic=0.75; 95% confidence interval [CI] 0.48–1.0). Primary efficacy and safety event rates were 3.3% (95% CI 0.3–11.5%) and 1.4% (0.03–7.4%). CONCLUSIONS The P/F phase of Kids-DOTT has demonstrated validity of vascular imaging findings of occlusion as a randomization criterion, and defined randomization, retention, and endpoint rates to inform the fully-powered RCT.

Currently available treatments for secondary progressive multiple sclerosis(SPMS) have limited efficacy and/or safety concerns. Adipose-mesenchymal derived stem cells(AdMSCs) represent a promising option and can be readily obtained using minimally invasive procedures. In this triple-blind, placebo-controlled study, cell samples were obtained from consenting patients by lipectomy and subsequently expanded. Patients were randomized to a single infusion of placebo, low-dose(1x106cells/kg) or high-dose(4x106cells/kg) autologous AdMSC product and followed for 12 months. Safety was monitored recording adverse events, laboratory parameters, vital signs and spirometry. Expanded disability status score (EDSS), magnetic-resonance-imaging, and other measures of possible treatment effects were also recorded. Thirty-four patients underwent lipectomy for AdMSCs collection, were randomized and thirty were infused (11 placebo, 10 low-dose and 9 high-dose); 4 randomized patients were not infused because of karyotype abnormalities in the cell product. Only one serious adverse event was observed in the treatment arms (urinary infection, considered not related to study treatment). No other safety parameters showed changes. Measures of treatment effect showed an inconclusive trend of efficacy. Infusion of autologous AdMSCs is safe and feasible in patients with SPMS. Larger studies and probably treatment at earlier phases would be needed to investigate the potential therapeutic benefit of this technique.

Self-administration of subcutaneous depot medroxyprogesterone acetate (DMPA-sc) is feasible, acceptable, and effective. Our objective was to compare one-year continuation of DMPA-sc between women randomized to self-administration versus clinic administration. We randomized 401 females ages 15-44 requesting DMPA at clinics in Texas and New Jersey to self-administration or clinic administration in a 1:1 allocation. Clinic staff taught participants randomized to self-administration to self-inject and observed the first injection; participants received instructions, a sharps container, and three doses for home use. Participants randomized to clinic administration received usual care. All participants received DMPA-sc at no cost and injection reminders via text message or email. We conducted follow-up surveys at six and 12 months. Three hundred thirty-six participants (84%) completed the 12-month survey; 316 completed both follow-up surveys (an 80% response rate excluding eight withdrawals). Participants ranged in age from 16-44. One-year DMPA continuous use was 69% in the self-administration group and 54% in the clinic group (p=.005). There were three self-reported pregnancies during the study period, all occurred in the clinic group; all three women had discontinued DMPA and one reported her pregnancy as intended. Among the self-administration group, 97% reported that self-administration was very or somewhat easy; 87% would recommend self-administration of DMPA-sc to a friend. Among the clinic group, 52% reported interest in self-administration in the future. Satisfaction was similar between groups. No serious adverse events were reported. DMPA self-administration improves contraceptive continuation and is a feasible and acceptable option for women and adolescents. Self-administration of subcutaneous DMPA can improve contraceptive access, autonomy, and continuation, and is a feasible and acceptable option for women and adolescents. It should be made widely available as an option for women and adolescents. Copyright © 2017 Elsevier Inc. All rights reserved.

Medical events including acute illness and injury are among the most common potentially traumatic experiences for children. Despite the scope of the problem, only limited resources are available for prevention of posttraumatic stress symptoms (PTSS) after pediatric medical events. Web-based programs provide a low-cost, accessible means to reach a wide range of families and show promise in related areas of child mental health. To describe the design of a randomized controlled trial that will evaluate feasibility and estimate preliminary efficacy of Coping Coach, a web-based preventive intervention to prevent or reduce PTSS after acute pediatric medical events. Seventy children and their parents will be randomly assigned to either an intervention or a waitlist control condition. Inclusion criteria require that children are aged 8-12 years, have experienced a medical event, have access to Internet and telephone, and have sufficient competency in the English language to complete measures and understand the intervention. Participants will complete baseline measures and will then be randomized to the intervention or waitlist control condition. Children in the intervention condition will complete module 1 (Feelings Identification) in the hospital and will be instructed on how to complete modules 2 (Appraisals) and 3 (Avoidance) online. Follow-up assessments will be conducted via telephone at 6, 12, and 18 weeks after the baseline assessment. Following the 12-week assessment, children in the waitlist control condition will receive instructions for completing the intervention. Primary study outcomes include data on intervention feasibility and outcomes (child appraisals, coping, PTSS and health-related quality of life). Results will provide data on the feasibility of the implementation of the Coping Coach intervention and study procedures as well as estimations of efficacy to determine sample size for a larger study. Potential strengths and limitations of this design are discussed.

The aim of this study was to assess the feasibility and potential benefit of a brief psychosocial intervention based on cognitive-behavioral therapy performed in addition to early palliative care (PC) in the reduction of depressive symptoms among patients with advanced cancer. An open-label randomized phase II clinical trial with two intervention arms and one control group. Patients with advanced cancer starting palliative chemotherapy and who met the selection criteria were included. The participants were randomly allocated to three arms: arm A, five weekly sessions of psychosocial intervention combined with early PC; arm B, early PC only; and arm C, standard cancer treatment. Feasibility was investigated by calculating rates (%) of inclusion, attrition, and contamination (% of patients from Arm C that received PC). Scores of depression (primary aim), anxiety, and quality of life were measured at baseline and 45, 90, 120, and 180 days after randomization. From the total of 613 screened patients (10.3% inclusion rate), 19, 22, and 22 patients were allocated to arms A, B, and C, respectively. Contamination and attrition rates (180 days) were 31.8% and 38.0%, respectively. No interaction between the arms and treatments were found. Regarding effect sizes, there was a moderate benefit in arm A over arms B and C in emotional functioning (-0.66 and -0.61, respectively) but a negative effect of arm A over arm C in depression (-0.74). Future studies to be conducted with this population group need to revise the eligibility criteria and make them less restrictive. In addition, the need for arm C is questioned due to high contamination rate. The designed psychosocial intervention was not able to reduce depressive symptoms when combined with early PC. Further studies are warrant to evaluate the intervention on-demand and in subgroups of high risk of anxiety/depression. Clinical Trials identifier NCT02133274 . Registered May 6, 2014.

Background Medical events including acute illness and injury are among the most common potentially traumatic experiences for children. Despite the scope of the problem, only limited resources are available for prevention of posttraumatic stress symptoms (PTSS) after pediatric medical events. Web-based programs provide a low-cost, accessible means to reach a wide range of families and show promise in related areas of child mental health. Objectives To describe the design of a randomized controlled trial that will evaluate feasibility and estimate preliminary efficacy of Coping Coach, a web-based preventive intervention to prevent or reduce PTSS after acute pediatric medical events. Method Seventy children and their parents will be randomly assigned to either an intervention or a waitlist control condition. Inclusion criteria require that children are aged 8–12 years, have experienced a medical event, have access to Internet and telephone, and have sufficient competency in the English language to complete measures and understand the intervention. Participants will complete baseline measures and will then be randomized to the intervention or waitlist control condition. Children in the intervention condition will complete module 1 (Feelings Identification) in the hospital and will be instructed on how to complete modules 2 (Appraisals) and 3 (Avoidance) online. Follow-up assessments will be conducted via telephone at 6, 12, and 18 weeks after the baseline assessment. Following the 12-week assessment, children in the waitlist control condition will receive instructions for completing the intervention. Results Primary study outcomes include data on intervention feasibility and outcomes (child appraisals, coping, PTSS and health-related quality of life). Discussion Results will provide data on the feasibility of the implementation of the Coping Coach intervention and study procedures as well as estimations of efficacy to determine sample size for a larger study. Potential strengths and limitations of this design are discussed. PMID:23898396

To explore the effectiveness of a mentalization-based therapeutic intervention specifically developed for parents in entrenched conflict over their children. To the best of our knowledge, this is the first randomized controlled intervention study in the United Kingdom to work with both parents postseparation, and the first to focus on mentalization in this situation. Using a mixed-methods study design, 30 parents were randomly allocated to either mentalization-based therapy for parental conflict-Parenting Together, or the Parents' Group, a psycho-educational intervention for separated parents based on elements of the Separated Parents Information Program-part of the U.K. Family Justice System and approximating to treatment as usual. Given the challenges of recruiting parents in these difficult circumstances, the sample size was small and permitted only the detection of large differences between conditions. The data, involving repeated measures of related individuals, was explored statistically, using hierarchical linear modeling, and qualitatively. Significant findings were reported on the main predicted outcomes, with clinically important trends on other measures. Qualitative findings further contributed to the understanding of parents' subjective experience, pre- and posttreatment. Findings indicate that a larger scale randomized controlled trial would be worthwhile. These encouraging findings shed light on the dynamics maintaining these high-conflict situations known to be damaging to children. We established that both forms of intervention were acceptable to most parents, and we were able to operate a random allocation design with extensive quantitative and qualitative assessments of the kind that would make a larger-scale trial feasible and productive.

Obese women are at increased risks for complications during pregnancy, birth and in their infants. Although guidelines have been established for the clinical care of obese pregnant women, management is sometimes suboptimal. Our goal was to determine the feasibility of implementing and testing a clinical carepath for obese pregnant women compared to standard care, in a pilot cluster randomized controlled trial (RCT). A pragmatic pilot cluster RCT was conducted, randomly allocating eight clinics to the carepath or standard care for obese pregnant women. Women were eligible if they had a prepregnancy body mass index of ≥ 30 kg/m 2 and a viable singleton < 21 weeks. The primary outcomes were the feasibility of conducting a full-scale cluster RCT (defined as > 80%: randomization of clinics, use in eligible women, and completeness of follow-up) and of the intervention (defined as > 80%: compliance with each step in the carepath, and recommendation of the carepath by clinicians to a colleague). All eight approached clinics agreed to participate and were randomized. Half of the intervention clinics used the carepath, resulting in < 80% uptake of eligible women. High follow-up (99.5%) was achieved, in 188 of 189 women. The carepath was feasible for numerous guideline-directed recommendations for screening, but less so for counselling topics. When the carepath was used in the majority of women, all clinicians, most of whom were midwives, reported they would recommend it to a colleague. The intervention group had significantly higher overall adherence to the guideline recommendations compared to control (relative risk 1.71, 95% confidence interval 1.57-1.87). In this pragmatic pilot cluster RCT, a guideline-directed clinical carepath improved some aspects of care of obese pregnant women and was recommended by clinicians, particularly midwives. A cluster RCT may not be feasible in a mix of obstetric and midwifery clinics, but may be feasible in midwifery clinics. This pragmatic pilot cluster RCT was registered on clinicaltrials.gov (identifier: NCT02534051 ).

Despite its well-established benefits, physical activity (PA) engagement is low in the adult population; evidence suggests that this is especially a concern for women > 60 years. The purpose of this mixed methods study was to explore the feasibility of a six-week randomized control trial of Self-Determination Theory-based dance and walking programs for older women. Primary outcomes were feasibility measures: recruitment, retention, and satisfaction. Secondary outcomes included self-reported PA, behavioural regulations, and psychological needs. Thirty-five women completed the study (M = 62.8 ± 4.8 years), representing 39% recruitment and 95% retention rate. Both programs were highly attended. Exploratory effect sizes for secondary measures were promising. Emergent themes highlighted the importance of servant leadership concepts in the group setting for motivating PA. Our findings provide support for expanding this trial to a full-scale study.

To evaluate the feasibility and effectiveness of adding object-related bilateral symmetrical training to mirror therapy (MT) to improve upper limb (UL) activity in chronic stroke patients. Sixteen patients with moderate UL impairment were randomly allocated to either the experimental (EG) or control (CG) group. Both groups performed 1 hour sessions, 3 days/week for 4 weeks, involving object-related bilateral symmetrical training. EG performed the tasks observing their nonparetic UL reflected in the mirror, while CG observed the paretic UL directly. The primary outcome measure was unilateral and bilateral UL activity according to the Test d'Évaluation des Membres Supérieurs de Personnes Âgées (TEMPA). All measurements were taken at baseline, post-training, and follow-up (2 weeks). TEMPA total score showed the main effect of time. Significant improvement was found for bilateral but not unilateral tasks. Both groups showed gains after training, with no differences between them. This study showed the feasibility of adding object-related bilateral training to MT. Both types of training improved UL bilateral activity; however, a larger sample is required for a definitive study. Other studies need to be carried out to evaluate the effectiveness of combining more distal-oriented movements and object-related unilateral training to improve these effects in chronic stroke patients.

A feasibility study on the use of shape memory alloys (SMA) for suppression of the random response of composite panels due to acoustic loads at elevated temperatures is presented. The constitutive relations for a composite lamina with embedded SMA fibers are developed. The finite element governing equations and the solution procedures for a composite plate subjected to combined acoustic and thermal loads are presented. Solutions include: 1) Critical buckling temperature; 2) Flat panel random response; 3) Thermal postbuckling deflection; 4) Random response of a thermally buckled panel. The preliminary results demonstrate that the SMA fibers can completely eliminate the thermal postbuckling deflection and significantly reduce the random response at elevated temperatures.

Multivariate quadratic ( ) cryptography requires the use of long public and private keys to ensure a sufficient security level, but this is not favorable to embedded systems, which have limited system resources. Recently, various approaches to cryptography using reduced public keys have been studied. As a result of this, at CHES2011 (Cryptographic Hardware and Embedded Systems, 2011), a small public key scheme, was proposed, and its feasible implementation on an embedded microprocessor was reported at CHES2012. However, the implementation of a small private key scheme was not reported. For efficient implementation, random number generators can contribute to reduce the key size, but the cost of using a random number generator is much more complex than computing on modern microprocessors. Therefore, no feasible results have been reported on embedded microprocessors. In this paper, we propose a feasible implementation on embedded microprocessors for a small private key scheme using a pseudo-random number generator and hash function based on a block-cipher exploiting a hardware Advanced Encryption Standard (AES) accelerator. To speed up the performance, we apply various implementation methods, including parallel computation, on-the-fly computation, optimized logarithm representation, vinegar monomials and assembly programming. The proposed method reduces the private key size by about 99.9% and boosts signature generation and verification by 5.78% and 12.19% than previous results in CHES2012. PMID:24651722

Background: Among Alaska Native women residing in the Yukon-Kuskokwim (Y-K) Delta region of Western Alaska, about 79% smoke cigarettes or use smokeless tobacco during pregnancy. Treatment methods developed and evaluated among Alaska Native pregnant tobacco users do not exist. This pilot study used a randomized two-group design to assess the feasibility and acceptability of a targeted cessation intervention for Alaska Native pregnant women. Methods: Recruitment occurred over an 8-month period. Enrolled participants were randomly assigned to the control group (n = 18; brief face-to-face counseling at the first visit and written materials) or to the intervention group (n = 17) consisting of face-to-face counseling at the first visit, four telephone calls, a video highlighting personal stories, and a cessation guide. Interview-based assessments were conducted at baseline and follow-up during pregnancy (≥60 days postrandomization). Feasibility was determined by the recruitment and retention rates. Results: The participation rate was very low with only 12% of eligible women (35/293) enrolled. Among enrolled participants, the study retention rates were high in both the intervention (71%) and control (94%) groups. The biochemically confirmed abstinence rates at follow-up were 0% and 6% for the intervention and control groups, respectively. Discussion: The low enrollment rate suggests that the program was not feasible or acceptable. Alternative approaches are needed to improve the reach and efficacy of cessation interventions for Alaska Native women. PMID:20018946

Repeated epidemiological surveys show no decline in depression although uptake of treatments has grown. Universal depression prevention interventions are effective in schools but untested rigorously in adulthood. Selective prevention programmes have poor uptake. Universal interventions may be more acceptable during routine healthcare contacts for example antenatally. One study within routine postnatal healthcare suggested risk of postnatal depression could be reduced in non-depressed women from 11% to 8% by giving health visitors psychological intervention training. Feasibility and effectiveness in other settings, most notably antenatally, is unknown. We conducted an external pilot study using a cluster trial design consisting of recruitment and enhanced psychological training of randomly selected clusters of community midwives (CMWs), recruitment of pregnant women of all levels of risk of depression, collection of baseline and outcome data prior to childbirth, allowing time for women 'at increased risk' to complete CMW-provided psychological support sessions. Seventy-nine percent of eligible women approached agreed to take part. Two hundred and ninety-eight women in eight clusters participated and 186 termed 'at low risk' for depression, based on an Edinburgh Perinatal Depression Scale (EPDS) score of <12 at 12 weeks gestation, provided baseline and outcome data at 34 weeks gestation. All trial protocol procedures were shown to be feasible. Antenatal effect sizes in women 'at low risk' were similar to those previously demonstrated postnatally. Qualitative work confirmed the acceptability of the approach to CMWs and intervention group women. A fully powered trial testing universal prevention of depression in pregnancy is feasible, acceptable and worth undertaking.

Inflammatory cytokines occur in the circulation and in the tissues after brain death and have been associated with dysfunction of donor organs before and after transplantation. To determine the feasibility of removing cytokines using a hemoadsorption device. Two-center, randomized, open-label, feasibility study in which brain-dead subjects were randomized to two treatment groups. Two U.S. academic hospitals. Eight brain-dead subjects deemed unsuitable for organ donation by respective organ procurement organizations. After obtaining consent from families, subjects were treated with hemoadsorption for 4 hrs using CytoSorb. Effects on cytokines (tumor necrosis factor, interleukin [IL]-6, and IL-10) were assessed both across the device and in the plasma over time. Feasibility for cytokine removal was assessed using objective criteria. Cytokine removal across the CytoSorb device ranged from 4% to 30% and was not significantly different from 1 hr to 4 hrs. Overall removal was greatest for IL-6, 28% (p = .006), and least for tumor necrosis factor, 8.5% (p = .13). Plasma concentrations of both IL-6 and tumor necrosis factor, but not IL-10, were significantly reduced after the first hour of therapy; mean differences were -13% +/- 7% for IL-6 (p = .039), -23% +/- 9% for tumor necrosis factor (p = .02), and -2% +/- 7% of IL-10 (p = 23). However, plasma concentrations for all three cytokines increased over time and were above baseline by the end of the intervention. No adverse effects of therapy were observed. However, removal of cortisol and triiodothyronine was similar to removal of cytokines. Hemoadsorption for removal of cytokines in brain-dead subjects is feasible. Evaluation of possible clinical benefit will require controlled trials in actual donors. However, the significant capacity for cytokine removal and absence of adverse events suggest that such trials are warranted.

Background Little is known about the feasibility of providing massage or music therapy to medical inpatients at urban safety-net hospitals or the impact these treatments may have on patient experience. Objective To determine the feasibility of providing massage and music therapy to medical inpatients and to assess the impact of these interventions on patient experience. Design Single-center 3-arm feasibility randomized controlled trial. Setting Urban academic safety-net hospital. Patients Adult inpatients on the Family Medicine ward. Interventions Massage therapy consisted of a standardized protocol adapted from a previous perioperative study. Music therapy involved a preference assessment, personalized compact disc, music-facilitated coping, singing/playing music, and/or songwriting. Credentialed therapists provided the interventions. Measurements Patient experience was measured with the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) within 7 days of discharge. We compared the proportion of patients in each study arm reporting “top box” scores for the following a priori HCAHPS domains: pain management, recommendation of hospital, and overall hospital rating. Responses to additional open-ended postdischarge questions were transcribed, coded independently, and analyzed for common themes. Results From July to December 2014, 90 medical inpatients were enrolled; postdischarge data were collected on 68 (76%) medical inpatients. Participants were 70% females, 43% non-Hispanic black, and 23% Hispanic. No differences between groups were observed on HCAHPS. The qualitative analysis found that massage and music therapy were associated with improved overall hospital experience, pain management, and connectedness to the massage or music therapist. Conclusions Providing music and massage therapy in an urban safety-net inpatient setting was feasible. There was no quantitative impact on HCAHPS. Qualitative findings suggest benefits related to an improved hospital experience, pain management, and connectedness to the massage or music therapist. PMID:29085740

Prevalence of type 2 diabetes mellitus is increasing due to lifestyle changes, particularly affecting those genetically at risk. We developed DiAlert as a targeted group-based intervention aimed to promote intrinsic motivation and action planning for lifestyle changes and weight loss in first degree relatives of patients with type 2 diabetes mellitus.The main objective of the pilot of the DiAlert intervention was to assess fidelity, feasibility and acceptability prior to starting the randomized controlled trial. Individuals with a family history of type 2 diabetes mellitus were self-identified and screened for eligibility. DiAlert consists of two group sessions. Feasibility, fidelity, acceptability and self-reported perceptions and behavioral determinants were evaluated in a pre-post study using questionnaires and observations. Determinants of behavior change were analyzed using paired-samples t tests and Wilcoxon signed rank tests. DiAlert was delivered to two groups of first degree relatives of patients with type 2 diabetes mellitus (N = 9 and N = 12). Feasibility and fidelity were confirmed. Overall, the DiAlert group sessions were positively evaluated (8.0 on a scale of 1 to 10) by participants. The intervention did not impact perceived susceptibility or worry about personal diabetes risk. Action planning with regard to changing diet and physical activity increased. DiAlert proved feasible and was well-accepted by participants. Positive trends in action planning indicate increased likelihood of actual behavior change following DiAlert. Testing the effectiveness in a randomized controlled trial is imperative. Netherlands National Trial Register (NTR): NTR2036.

While survival rates for preterm infants have increased, the risk for adverse long-term neurodevelopmental and behavioral outcomes remains very high. In response to the need for novel, evidence-based interventions that prevent such outcomes, we have assessed Family Nurture Intervention (FNI), a novel dual mother-infant intervention implemented while the infant is in the Neonatal Intensive Care Unit (NICU). Here, we report the first trial results, including the primary outcome measure, length of stay in the NICU and, the feasibility and safety of its implementation in a high acuity level IV NICU. The FNI trial is a single center, parallel-group, randomized controlled trial at Morgan Stanley Children's Hospital for mothers and their singleton or twin infants of 26-34 weeks gestation. Families were randomized to standard care (SC) or (FNI). FNI was implemented by nurture specialists trained to facilitate affective communication between mother and infant during specified calming interactions. These interactions included scent cloth exchange, sustained touch, vocal soothing and eye contact, wrapped or skin-to-skin holding, plus family-based support interactions. A total of 826 infants born between 26 and 34 weeks during the 3.5 year study period were admitted to the NICU. After infant and mother screening plus exclusion due to circumstances that prevented the family from participating, 373 infants were eligible for the study. Of these, we were unable to schedule a consent meeting with 56, and consent was withheld by 165. Consent was obtained for 150 infants from 115 families. The infants were block randomized to groups of N = 78, FNI and N = 72, SC. Sixteen (9.6%) of the randomized infants did not complete the study to home discharge, 7% of those randomized to SC and 12% of FNI infants. Mothers in the intervention group engaged in 3 to 4 facilitated one- to two-hour sessions/week. Intent to treat analyses revealed no significant difference between groups in medical complications. The mean length of stay was not significantly affected by the intervention. There was no significant effect demonstrated with this intervention amount on the primary short-term outcome, length of stay. FNI can be safely and feasibly implemented within a level IV NICU.

To assess the feasibility of Wii.n.Walk for improving walking capacity in older adults with lower limb amputation. A parallel, evaluator-blind randomized controlled feasibility trial. Community-living. Individuals who were ⩾50 years old with a unilateral lower limb amputation. Wii.n.Walk consisted of Wii Fit training, 3x/week (40 minute sessions), for 4 weeks. Training started in the clinic in groups of 3 and graduated to unsupervised home training. Control group were trained using cognitive games. Feasibility indicators: trial process (recruitment, retention, participants' perceived benefit from the Wii.n.Walk intervention measured by exit questionnaire), resources (adherence), management (participant processing, blinding), and treatment (adverse event, and Cohen's d effect size and variance). Primary clinical outcome: walking capacity measured using the 2 Minute Walk Test at baseline, end of treatment, and 3-week retention. Of 28 randomized participants, 24 completed the trial (12/arm). Median (range) age was 62.0 (50-78) years. Mean (SD) score for perceived benefit from the Wii.n.Walk intervention was 38.9/45 (6.8). Adherence was 83.4%. The effect sizes for the 2 Minute Walk Test were 0.5 (end of treatment) and 0.6 (3-week retention) based on intention to treat with imputed data; and 0.9 (end of treatment) and 1.2 (3-week retention) based on per protocol analysis. The required sample size for a future larger RCT was deemed to be 72 (36 per arm). The results suggested the feasibility of the Wii.n.Walk with a medium effect size for improving walking capacity. Future larger randomized controlled trials investigating efficacy are warranted.

Recent prevention research has established the efficacy of some child sexual abuse prevention programs targeting adults; however, less is known about the feasibility of implementing such programs. The current study examines the feasibility and acceptability of a child sexual abuse prevention program for child care professionals provided in two different formats: in person and Web based. The sample consisted of 188 child care professionals from a large-scale, multisite, randomized controlled trial. Findings indicate that both in-person and online training formats are feasible to implement and acceptable to professionals. When comparing formats, the in-person format was favored in terms of comfort level and likelihood of sharing information with others. These findings have significant implications for dissemination of child sexual abuse prevention programs for child care professionals.

While much psychiatric research is based on randomized controlled trials (RCTs), where patients are randomly assigned to treatments, sometimes RCTs are not feasible. This paper describes propensity score approaches, which are increasingly used for estimating treatment effects in non-experimental settings. The primary goal of propensity score methods is to create sets of treated and comparison subjects who look as similar as possible, in essence replicating a randomized experiment, at least with respect to observed patient characteristics. A study to estimate the metabolic effects of antipsychotic medication in a sample of Florida Medicaid beneficiaries with schizophrenia illustrates methods. PMID:20563313

Existing psychological therapies for bipolar disorders have been found to have mixed results, with a consensus that they provide a significant, but modest, effect on clinical outcomes. Typically, these approaches have focused on promoting strategies to prevent future relapse. An alternative treatment approach, termed 'Think Effectively About Mood Swings' (TEAMS) addresses current symptoms, including subclinical hypomania, depression and anxiety, and promotes long-term recovery. Following the publication of a theoretical model, a range of research studies testing the model and a case series have demonstrated positive results. The current study reports the protocol of a feasibility randomized controlled trial to inform a future multi-centre trial. A target number of 84 patients with a diagnosis of bipolar I or II disorder, or bipolar disorder not-otherwise-specified are screened, allocated to a baseline assessment and randomized to either 16 sessions of TEAMS therapy plus treatment-as-usual (TAU) or TAU. Patients complete self-report inventories of depression, anxiety, recovery status and bipolar cognitions targeted by TEAMS. Assessments of diagnosis, bipolar symptoms, medication, access to services and quality of life are conducted by assessors blind to treatment condition at 3, 6, 12 and 18 months post-randomization. The main aim is to evaluate recruitment and retention of participants into both arms of the study, as well as adherence to therapy, to determine feasibility and acceptability. It is predicted that TEAMS plus TAU will reduce self-reported depression in comparison to TAU alone at six months post-randomization. The secondary hypotheses are that TEAMS will reduce the severity of hypomanic symptoms and anxiety, reduce bipolar cognitions, improve social functioning and promote recovery compared to TAU alone at post-treatment and follow-up. The study also incorporates semi-structured interviews about the experiences of previous treatment and the experience of TEAMS therapy that will be subject to qualitative analyses to inform future developments of the approach. The design will provide preliminary evidence of efficacy, feasibility, acceptability, uptake, attrition and barriers to treatment to design a definitive trial of this novel intervention compared to treatment as usual. This trial was registered with Current Controlled Trials (ISRCTN83928726) on registered 25 July 2014.

Children of anxious parents are at high risk of anxiety disorders themselves. The evidence suggests that this is due to environmental rather than genetic factors. However, we currently do little to reduce this risk of transmission. There is evidence that supporting parenting in those with mental health difficulties can ameliorate this risk. Therefore, the objective of this study was to test the feasibility of a new one-session, group-based, preventive parenting intervention for parents with anxiety disorders. Feasibility Randomized Controlled Trial. A total of 100 parents with anxiety disorders, recruited from adult mental health services in England (and child aged 3-9 years), were randomized to receive the new intervention (a 1-day, group workshop), or to treatment as usual. Children's anxiety disorder and anxiety symptoms were assessed to 12 months by outcome assessors who were blind to group allocation. Exploratory analyses were conducted on an intention to treat basis, as far as possible. A total of 51 participants were randomized to the intervention condition and 49 to the control condition (82% and 80% followed to 12 months, respectively). The attendance rate was 59%, and the intervention was highly acceptable to parents who received it. The RCT was feasible, and 12-month follow-up attrition rates were low. Children whose parents were in the control condition were 16.5% more likely to have an anxiety disorder at follow-up than those in the intervention group. No adverse events were reported. An inexpensive, light-touch, psycho-educational intervention may be useful in breaking the intergenerational cycle of transmission of anxiety disorders. A substantive trial is warranted. Anxiety disorders run in families, but we currently do little to help anxious parents to raise confident children. A brief group workshop was highly acceptable to such parents and was very inexpensive to run. Children of parents who took part in the brief intervention were 16.5% less likely to have an anxiety disorder, 1 year later, than children whose parents were in the control group. This was a feasibility study, and while it showed that both the intervention and the research were feasible, the study needs replicating with a much larger sample. Many parents faced barriers to attending the workshop, and future efforts should focus on widening accessibility. We were unable to obtain sufficient self-report data from children, so the outcomes are based on parent report only. © 2018 The British Psychological Society.

Background Old adults admitted to the hospital are at severe risk of functional loss during hospitalization. Early in-hospital physical rehabilitation programs appear to prevent functional loss in geriatric patients. The first aim of this review was to investigate the effect of early physical rehabilitation programs on physical functioning among geriatric patients acutely admitted to the hospital. The second aim was to evaluate the feasibility of early physical rehabilitation programs. Methods Two searches, one for physical functioning and one for feasibility, were conducted in PubMed, CINAHL, and EMBASE. Additional studies were identified through reference and citation tracking. To be included articles had to report on in-hospital early physical rehabilitation of patients aged 65 years and older with an outcome measure of physical functioning. Studies were excluded when the treatment was performed on specialized units other than geriatric units. Randomized controlled trials were included to examine the effect of early physical rehabilitation on physical functioning, length of stay and discharge destination. To investigate feasibility also non randomized controlled trials were added. Results Fifteen articles, reporting on 13 studies, described the effect on physical functioning. The early physical rehabilitation programs were classified in multidisciplinary programs with an exercise component and usual care with an exercise component. Multidisciplinary programs focussed more on facilitating discharge home and independent ADL, whereas exercise programs aimed at improving functional outcomes. At time of discharge patients who had participated in a multidisciplinary program or exercise program improved more on physical functional tests and were less likely to be discharged to a nursing home compared to patients receiving only usual care. In addition, multidisciplinary programs reduced the length of hospital stay significantly. Follow-up interventions improved physical functioning after discharge. The feasibility search yielded four articles. The feasibility results showed that early physical rehabilitation for acutely hospitalized old adults was safe. Adherence rates differed between studies and the recruitment of patients was sometimes challenging. Conclusions Early physical rehabilitation care for acutely hospitalized old adults leads to functional benefits and can be safely executed. Further research is needed to specifically quantify the physical component in early physical rehabilitation programs. PMID:24112948

Exercise may have beneficial effects on both well-being and walking ability in multiple sclerosis (MS). Exercise is shown to be neuroprotective in rodents and may also enhance cognitive function in humans. It may, therefore, be particularly useful for MS patients with pronounced neurodegeneration. To investigate the potential of standardized exercise as a therapeutic intervention for progressive MS, in a randomized-controlled pilot trial. Patients with progressive MS and moderate disability (Expanded Disability Status Scale (EDSS) of 4-6) were randomized to one of three exercise interventions (arm ergometry, rowing, bicycle ergometry) for 8-10 weeks or a waitlist control group. We analyzed the drop-out rate as a measure of feasibility. The primary endpoint of the study was aerobic fitness. Secondary endpoints were walking ability, cognitive function as measured by a neuropsychological test battery, depression and fatigue. A total of 42 patients completed the trial (10.6% drop-out rate). Significant improvements were seen in aerobic fitness. In addition, exercise improved walking ability, depressive symptoms, fatigue and several domains of cognitive function. This study indicated that aerobic training is feasible and could be beneficial for patients with progressive MS. Larger exercise studies are needed to confirm the effect on cognition.

This pilot study used a randomized controlled trial design to examine the feasibility and explore initial outcomes of a twice weekly, 8-session Child Directed Interaction Training (CDIT) program for children living in kinship care. Participants included 14 grandmothers and great-grandmothers with their 2- to 7-year-old children randomized either to CDIT or a waitlist control condition. Training was delivered at a local, community library with high fidelity to the training protocol. There was no attrition in either condition. After training, kinship caregivers in the CDIT condition demonstrated more positive relationships with their children during behavioral observation. The caregivers in the CDIT condition also reported clinically and statistically significant decreases in parenting stress and caregiver depression, as well as fewer externalizing child behavior problems than waitlist controls. Parent daily report measures indicated significant changes in disciplining that included greater use of limit-setting and less use of critical verbal force. Results appeared stable at 3-month follow-up. Changes in child internalizing behaviors and caregiver use of non-critical verbal force were not seen until 3-month follow-up. Results of this pilot study suggest both the feasibility of conducting full scale randomized clinical trials of CDIT in the community and the promise of this approach for providing effective parent training for kinship caregivers.

Not all patients with post-traumatic stress disorder (PTSD) respond to cognitive behavioural therapy (CBT). Literature suggests group music therapy might be beneficial in treating PTSD. However, feasibility and effectiveness have not been assessed. The study objectives were to assess whether group music therapy was feasible for patients who did not respond to CBT, and whether it has an effect on PTSD symptoms and depression. The study employed mixed methods comprising of an exploratory randomized controlled trial, qualitative content analysis of therapy, and patient interviews. Patients with significant PTSD symptoms (n = 17) following completion of CBT were randomly assigned to treatment (n = 9) or control groups (n = 8). The treatment group received 10 weeks of group music therapy after which exit interviews were conducted. Control group patients were offered the intervention at the end of the study. Symptoms were assessed on the Impact of Events Scale-Revised and Beck Depression Inventory II at the beginning and end of treatment. Treatment-group patients experienced a significant reduction in severity of PTSD symptoms (-20.18; 95% confidence interval [CI]: [-31.23, -9.12]) and a marginally significant reduction in depression (-11.92; 95%CI: [-24.05, 0.21]) at 10 weeks from baseline compared to the control. Patients viewed music therapy as helpful and reported experiences concur with current literature. Group music therapy appears feasible and effective for PTSD patients who have not sufficiently responded to CBT. Limitations include the small sample size and lack of blinding. Further research should address these limitations, test sustainability, and identify specific factors that address symptoms in treatment. ©2011 The British Psychological Society.

Most existing evidence-based sexual health interventions focus on individual-level behavior, even though there is substantial evidence that highlights the influential role of social environments in shaping adolescents’ behaviors and reproductive health outcomes. We developed Yo Puedo, a combined conditional cash transfer (CCT) and life skills intervention for youth to promote educational attainment, job training, and reproductive health wellness that we then evaluated for feasibility among 162 youth aged 16–21 years in a predominantly Latino community in San Francisco, CA. The intervention targeted youth’s social networks and involved recruitment and randomization of small social network clusters. In this paper we describe the design of the feasibility study and report participants’ baseline characteristics. Furthermore, we examined the sample and design implications of recruiting social network clusters as the unit of randomization. Baseline data provide evidence that we successfully enrolled high risk youth using a social network recruitment approach in community and school-based settings. Nearly all participants (95%) were high risk for adverse educational and reproductive health outcomes based on multiple measures of low socioeconomic status (81%) and/or reported high risk behaviors (e.g., gang affiliation, past pregnancy, recent unprotected sex, frequent substance use) (62%). We achieved variability in the study sample through heterogeneity in recruitment of the index participants, whereas the individuals within the small social networks of close friends demonstrated substantial homogeneity across sociodemographic and risk profile characteristics. Social networks recruitment was feasible and yielded a sample of high risk youth willing to enroll in a randomized study to evaluate a novel sexual health intervention. PMID:25358834

Objective To assess the feasibility, acceptability and changes in knowledge among cancer patients assigned to receive a 160 page book on experimental cancer therapies and clinical trials. Methods We enrolled 20 patients with cancer who had never participated in a clinical trial, and randomly assigned them to receive the book either during Week 1or Week 4 of the study. We collected baseline patient demographic and cancer related information as well as knowledge about cancer clinical trials at Week 0. Follow-up surveys were administered at Weeks 3 and 6 for both study groups. Comparisons were made within and between groups randomized to receive the book Early (at Week 1) to those who received it Later (at Week 4). Results One hundred percent of data were captured in both groups at baseline, which decreased to 77.8% by Week 6. The vast majority of participants found the book moderately or very useful (89% in the Early Group at Week 3 and 95.5% in the Late Group at Week 6). Within group pair-wise comparisons found significant difference between baseline and Week 6 in content-specific knowledge scores among participants in the Late Group (79% vs. 92.1%, p=0.01). Global knowledge scores increased significantly for variables reflecting knowledge that promotes decisions to participate in clinical trials. Conclusions Providing published reading material to patients with cancer is both feasible and acceptable. Offering information to patients about cancer clinical trials, using a book designed for patients with cancer may influence knowledge related to decision to participate in clinical trials.

Some breast cancer survivors report cognitive difficulties greater than 1 year after chemotherapy. Acetylcholinesterase inhibitors (AChEI) may improve cognitive impairment. We conducted a randomized, placebo-controlled, pilot study to assess the feasibility of using the AChEI, donepezil, to improve subjective and objective measures of cognitive function in breast cancer survivors. Women who received adjuvant chemotherapy 1-5 years prior with current cognitive dysfunction symptoms were randomized to 5 mg of donepezil/day vs placebo for 6 weeks and if tolerated 10 mg/day for 18 weeks for a total of 24 weeks. A battery of validated measures of attention, memory, language, visuomotor skills, processing speed, executive function, and motor dexterity and speed was administered at baseline and at 24 and 36 weeks. Subjective cognitive function, fatigue, sleep, mood, and health-related quality of life were evaluated at baseline and at 12, 24, and 36 weeks. Sixty-two patients were enrolled, 76 % completed the study, self-reported compliance was 98 %, and toxicities were minimal. At the end of treatment, the donepezil group performed significantly better than the control group on two parameters of memory-the Hopkins Verbal Learning Test -Revised (HVLT-R) Total Recall (p = 0.033) and HVLT-R Discrimination (p = 0.036). There were no significant differences on other cognitive variables or in subjective cognitive function or quality of life. Accrual to this feasibility trial was robust, retention was good, compliance was excellent, and toxicities were minimal. Randomized clinical trials in breast cancer survivors to improve cognitive dysfunction are feasible. A phase III trial testing the efficacy of donepezil is warranted given these pilot results.

The purpose of the study was to evaluate the feasibility and efficacy of robot-assisted hand rehabilitation in improving arm function abilities in sub-acute hemiplegic patients. Randomized controlled pilot study. Inpatient rehabilitation centers. Thirty hemiplegic stroke patients (Ashworth spasticity index <3) were recruited and randomly divided into a Treatment group (TG) and Control group (CG). Patients in the TG received intensive hand training with Gloreha, a hand rehabilitation glove that provides computer-controlled, repetitive, passive mobilization of the fingers, with multisensory feedback. Patients in the CG received the same amount of time in terms of conventional hand rehabilitation. Hand motor function (Motricity Index, MI), fine manual dexterity (Nine Hole Peg Test, NHPT) and strength (Grip and Pinch test) were measured at baseline and after rehabilitation, and the differences, (Δ) mean(standard deviation), compared between groups. Results Twenty-seven patients concluded the program: 14 in the TG and 13 in the CG. None of the patients refused the device and only one adverse event of rheumatoid arthritis reactivation was reported. Baseline data did not differ significantly between the two groups. In TG, ΔMI 23(16.4), ΔNHPT 0.16(0.16), ΔGRIP 0.27(0.23) and ΔPINCH 0.07(0.07) were significantly greater than in CG, ΔMI 5.2(9.2), ΔNHPT 0.02(0.07), ΔGRIP 0.03(0.06) and ΔPINCH 0.02(0.03)] ( p=0.002, p=0.009, p=0.003 and p=0.038, respectively). Gloreha Professional is feasible and effective in recovering fine manual dexterity and strength and reducing arm disability in sub-acute hemiplegic patients.

To explore feasibility and potential efficacy of on-line interventions for sleep quality following a traumatic brain injury (TBI). A two parallel-group, randomized controlled pilot study. Community-based. In all, 24 participants (mean age: 35.9 ± 11.8 years) who reported experiencing sleep difficulties between 3 and 36 months after a mild or moderate TBI. Participants were randomized to receive either a cognitive behaviour therapy or an education intervention on-line. Both interventions were self-completed for 20-30 minutes per week over a six-week period. The Pittsburgh Sleep Quality Index assessed self-reported sleep quality with actigraphy used as an objective measure of sleep quality. The CNS Vital Signs on-line neuropsychological test assessed cognitive functioning and the Rivermead Post-concussion Symptoms and Quality of Life after Brain Injury questionnaires were completed pre and post intervention. Both programmes demonstrated feasibility for use post TBI, with 83.3% of participants completing the interventions. The cognitive behaviour therapy group experienced significant reductions ( F = 5.47, p = 0.04) in sleep disturbance (mean individual change = -4.00) in comparison to controls post intervention (mean individual change = -1.50) with a moderate effect size of 1.17. There were no significant group differences on objective sleep quality, cognitive functioning, post-concussion symptoms or quality of life. On-line programmes designed to improve sleep are feasible for use for adults following mild-to-moderate TBI. Based on the effect size identified in this pilot study, 128 people (64 per group) would be needed to determine clinical effectiveness.

Acquired brain injury (ABI) during childhood typically causes behavior problems in the child and high levels of stress in the family. The aims of this study are: (1) to investigate the effectiveness and feasibility of a parenting intervention in improving behavior and self-regulation in Mexican children with ABI compared to telephone support; (2) to investigate the effectiveness and feasibility of a parenting intervention in improving parenting skills, parent self-efficacy and decreasing parental stress in parents of children with ABI compared to telephone support. Our secondary aims are (1) to explore the impact that parent characteristics have on the intervention outcomes; (2) to investigate if changes are maintained 3 months after the intervention. The research design is a blind randomized controlled trial (RCT). Eligible participants include children with a diagnosis of ABI, between 6 and 12 years of age, and their parents. Sixty-six children and their parents will be randomly allocated to either a parenting program group or telephone support group. The parenting program involves six face-to-face weekly group sessions of 2.5 h each. Participants in the control group receive an information sheet with behavioral strategies, and six weekly phone calls, in which strategies to improve academic skills are provided. Children and their parents are evaluated by blind assessors before the intervention, immediately after the intervention and 3-months post-intervention. This study will be the first to evaluate the efficacy and feasibility of a parenting program for Mexican parents of children with ABI. ACTRN12617000360314.

Background Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients. Quality of life (QOL) is impaired, and available treatments are of little benefit. This trial determined the feasibility of conducting a sham-controlled trial of acupuncture and whether acupuncture could prevent xerostomia among head/neck patients undergoing radiotherapy. Methods A sham controlled, feasibility trial was conducted at Fudan University Shanghai Cancer Center, Shanghai, China among patients with nasopharyngeal carcinoma undergoing radiotherapy. To determine feasibility of a sham procedure, 23 patients were randomized to real acupuncture (N = 11) or to sham acupuncture (N = 12). Patients were treated 3 times/week during their course of radiotherapy. Subjective measures were the Xerostomia Questionnaire (XQ) and MD Anderson Symptom Inventory for Head and Neck Cancer (MDASI-HN). Objective measures were unstimulated whole salivary flow rates (UWSFR) and stimulated salivary flow rates (SSFR). Patients were followed for 1 month after radiotherapy. Results XQ scores for acupuncture were significantly lower than sham controls starting in week 3 and lasted through the 1-month follow-up (all P’s < 0.001 except for week 3, which was 0.006), with clinically significant differences as follows: week 6 – RR 0.28 [95% CI, 0.10, 0.79]; week 11- RR 0.17 [95% CI, 0.03, 1.07]. Similar findings were seen for MDASI-HN scores and MDASI-Intrusion scores. Group differences for UWSFR and SSFR were not found. Conclusions In this small pilot study, true acupuncture given concurrently with radiotherapy significantly reduced xerostomia symptoms and improved QOL when compared with sham acupuncture. Large-scale, multi-center, randomized, placebo-controlled trials are now needed. PMID:22285177

To determine whether providing remote neurologic care into the homes of people with Parkinson disease (PD) is feasible, beneficial, and valuable. In a 1-year randomized controlled trial, we compared usual care to usual care supplemented by 4 virtual visits via video conferencing from a remote specialist into patients' homes. Primary outcome measures were feasibility, as measured by the proportion who completed at least one virtual visit and the proportion of virtual visits completed on time; and efficacy, as measured by the change in the Parkinson's Disease Questionnaire-39, a quality of life scale. Secondary outcomes included quality of care, caregiver burden, and time and travel savings. A total of 927 individuals indicated interest, 210 were enrolled, and 195 were randomized. Participants had recently seen a specialist (73%) and were largely college-educated (73%) and white (96%). Ninety-five (98% of the intervention group) completed at least one virtual visit, and 91% of 388 virtual visits were completed. Quality of life did not improve in those receiving virtual house calls (0.3 points worse on a 100-point scale; 95% confidence interval [CI] -2.0 to 2.7 points; p = 0.78) nor did quality of care or caregiver burden. Each virtual house call saved patients a median of 88 minutes (95% CI 70-120; p < 0.0001) and 38 miles per visit (95% CI 36-56; p < 0.0001). Providing remote neurologic care directly into the homes of people with PD was feasible and was neither more nor less efficacious than usual in-person care. Virtual house calls generated great interest and provided substantial convenience. NCT02038959. This study provides Class III evidence that for patients with PD, virtual house calls from a neurologist are feasible and do not significantly change quality of life compared to in-person visits. The study is rated Class III because it was not possible to mask patients to visit type. © 2017 American Academy of Neurology.

To evaluate the feasibility of Pilates exercise in older people to decrease falls risk and inform a larger trial. Pilot Randomized controlled trial. Community physiotherapy clinic. A total of 53 community-dwelling people aged ⩾60 years (mean age, 69.3 years; age range, 61-84). A 60-minute Pilates class incorporating best practice guidelines for exercise to prevent falls, performed twice weekly for 12 weeks. All participants received a letter to their general practitioner with falls risk information, fall and fracture prevention education and home exercises. Indicators of feasibility included: acceptability (recruitment, retention, intervention adherence and participant experience survey); safety (adverse events); and potential effectiveness (fall, fall injury and injurious fall rates; standing balance; lower limb strength; and flexibility) measured at 12 and 24 weeks. Recruitment was achievable but control group drop-outs were high (23%). Of the 20 participants who completed the intervention, 19 (95%) attended ⩾75% of the classes and reported classes were enjoyable and would recommend them to others. The rate of fall injuries at 24 weeks was 42% lower and injurious fall rates 64% lower in the Pilates group, however, was not statistically significant (P = 0.347 and P = 0.136). Standing balance, lower-limb strength and flexibility improved in the Pilates group relative to the control group (P < 0.05). Estimates suggest a future definitive study would require 804 participants to detect a difference in fall injury rates. A definitive randomized controlled trial analysing the effect of Pilates in older people would be feasible and is warranted given the acceptability and potential positive effects of Pilates on fall injuries and fall risk factors. The protocol for this study is registered with the Australian and New Zealand Clinical Trials Registry (ACTRN1262000224820). © The Author(s) 2015.

The study objectives were to ascertain whether a novel educational film class is an acceptable and feasible comparison group for a randomized controlled trial regarding the effects of an active mind-body therapy on cardiovascular disease risk in postmenopausal women. Seventy-five (75) participants attended a baseline assessment visit and were randomly assigned to either a yoga group or an educational film (control) group. Both groups attended two 90-minute classes/week for 8 weeks, followed by a second assessment visit. Those not attending the second assessment were classified as dropouts. Over 60 films covering a range of topics relevant to the study population were evaluated; 15 were selected by consensus of at least 2 researchers and 1 layperson. Each film session followed the same format: an informal greeting period, viewing of the film, and a 15-minute postfilm discussion. To determine acceptability and feasibility of the film class, potential between-group differences in dropout and attendance were examined, and participant feedback given during class and on end-of-study questionnaires were evaluated. The relation between group assignment and dropout was not significant (χ(2) [1, N = 75] = 0.14, p = 0.71). One-way analysis of variance (ANOVA) indicated no significant between-group difference in number of classes attended for the yoga (X = 13.67 ± 3.10) versus film group (13.26 ± 1.97), F(1,63) = 0.39, p = 0.53). Participant feedback regarding the film program was positive. These findings support the feasibility and acceptability of this educational film control. Easy to standardize and tailor to a variety of populations, this film program may offer an attractive alternative to the more traditional educational control.

Prostate cancer patients who have undergone androgen deprivation therapy (ADT) may experience cognitive impairment, yet there is an unmet need for nonpharmacological interventions to address cognitive impairment in this population. This study examines the feasibility, acceptability, and preliminary efficacy of a home-based computerized cognitive training (CCT) program to treat cancer-related cognitive impairment. Sixty men who had received ≥ 3 months of ADT were screened for at least mild cognitive or neurobehavioral impairment and randomized to 8 weeks of CCT or usual care. Follow-up assessments occurred immediately post-intervention or equivalent (T2) and 8 weeks later (T3). The acceptability of CCT was also assessed. Feasibility:A priori feasibility thresholds were partially met (i.e., randomization rate > 50%, retention rate > 70% excluding CCT drop-outs, but < 70% for intent-to-treat). Acceptability: Participants were mostly satisfied with CCT and found it somewhat enjoyable, though barriers to uptake existed. Preliminary efficacy: Linear mixed models indicated significant time by group effects favorable to CCT in reaction time (p = .01), but unfavorable to CCT in verbal and visual memory (ps < .05). Memory was temporarily suppressed in the CCT group at T2, but normalized by T3. There was no effect of CCT on self-reported cognitive functioning, neurobehavioral functioning, nor quality of life. This study provides tentative support for the feasibility and acceptability of CCT to treat mild cognitive impairment in ADT patients. CCT had a beneficial effect on reaction time, but temporarily suppressed memory. CCT's benefits may be limited to a narrow area of functioning. Larger-scale studies are needed.

There are no randomized trials comparing intravenous iron to RBC transfusion for the treatment of severe postpartum anaemia. The objectives of this study were to evaluate the feasibility of randomizing women with severe postpartum anaemia secondary to postpartum haemorrhage to RBC transfusion or intravenous iron, and to describe patient-reported outcomes, and haematological and iron parameters. Women with a postpartum haemorrhage exceeding 1000 ml and an Hb between 5·6 and 8·1 g/dl were randomized to 1500 mg of intravenous iron (n = 7) isomaltoside or RBC transfusion (n = 6). Participants completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale, and blood samples were drawn at inclusion, daily during the first week and at weeks 3, 8 and 12. We screened 162 women and included 13 (8%). There was no significant difference between groups in fatigue or depression scores. RBC transfusion was associated with a higher Hb on day 1, inhibition of reticulocytosis during the first week and low iron levels. Intravenous iron was associated with increased reticulocytosis during the first week, repleted iron stores and a higher Hb in weeks 3-12. This pilot study shows that intravenous iron could be an attractive alternative to RBC transfusion in severe postpartum anaemia, and that a larger trial is needed and feasible. © 2016 The Authors.

Background Childhood obesity has reached epidemic proportions in developed countries. Sedentary screen-based activities such as video gaming are thought to displace active behaviors and are independently associated with obesity. Active video games, where players physically interact with images onscreen, may have utility as a novel intervention to increase physical activity and improve body composition in children. The aim of the Electronic Games to Aid Motivation to Exercise (eGAME) study is to determine the effects of an active video game intervention over 6 months on: body mass index (BMI), percent body fat, waist circumference, cardio-respiratory fitness, and physical activity levels in overweight children. Methods/Design Three hundred and thirty participants aged 10–14 years will be randomized to receive either an active video game upgrade package or to a control group (no intervention). Discussion An overview of the eGAME study is presented, providing an example of a large, pragmatic randomized controlled trial in a community setting. Reflection is offered on key issues encountered during the course of the study. In particular, investigation into the feasibility of the proposed intervention, as well as robust testing of proposed study procedures is a critical step prior to implementation of a large-scale trial.

Aerobic exercise appears to have clinical benefits for many asthmatics, yet a complete understanding of the mechanisms underlying these benefits has not been elucidated at this time. The objective of this study was to determine feasibility for a larger, future study that will define the effect of aerobic exercise on cellular, molecular, and functional measures in adults with mild-moderate asthma. Recruited subjects were randomized into usual care (sedentary) or usual care with moderate intensity aerobic exercise treatment groups. Nineteen adults with mild-moderate asthma but without a recent history of exercise were recruited at the UAB Lung Health Center, Birmingham, AL. The exercise group underwent a 12 week walking program exercising at 60 - 75% of maximum heart rate (HRmax). Subjects self-monitored HRmax levels using heart rate monitors; exercise diaries and recreation center sign-in logs were also used. Functional measures, including lung function and asthma control scores, were evaluated for all subjects at pre- and post-study time-points; fitness measures were also assessed for subjects in the exercise group. Peripheral blood and nasal lavage fluid were collected from all subjects at pre- and post-study visits in order to evaluate cellular and molecular measures, including cell differentials and eosinophilic cationic protein (ECP). Sixteen subjects completed the prescribed protocol. Results show that subjects randomized to the exercise group adhered well (80%) to the exercise prescription and exhibited a trend toward improved fitness levels upon study completion. Both groups exhibited improvements in ACQ scores. No changes were observed in lung function (FEV1, FEV1/FVC), cell differentials, or ECP between groups. Results indicate that a moderate intensity aerobic exercise training program may improve asthma control and fitness levels without causing asthma deterioration in adult asthmatics. As such, these findings demonstrate the feasibility of the study protocol in preparation for a larger, clinical trial that will elucidate the functional consequences of aerobic exercise on asthmatic cellular and molecular responses.

Enabling self-management behaviors is considered important in order to develop coping strategies and confidence for managing life with a long-term condition. However, there is limited research into stroke-specific self-management interventions. The aim of this randomized controlled trial was to evaluate the feasibility of delivering the Bridges stroke self-management program in addition to usual stroke rehabilitation compared with usual rehabilitation only. Participants recruited from the referrals to a community stroke team were randomly allocated to the Bridges stroke self-management program, receiving either one session of up to one-hour per week over a six-week period in addition to usual stroke rehabilitation, or usual rehabilitation only. Feasibility was measured using a range of methods to determine recruitment and retention; adherence to the program; suitability and variability of outcome measures used; application and fidelity of the program; and acceptability of the program to patients, carers and professionals. Twenty-five people were recruited to the study over a 13-month period. Eight out of the 12 participants in the Bridges stroke self-management program received all six sessions; there was one withdrawal from the study. There were changes in outcomes between the two groups. Participants who received the Bridges stroke self-management program appeared to have a greater change in self-efficacy, functional activity, social integration and quality of life over the six-week intervention period and showed less decline in mood and quality of life at the three-month follow-up. Professionals found the program acceptable to use in practice, and feedback from participants was broadly positive. The findings from this study appear promising, but questions remain regarding the feasibility of delivering the Bridges stroke self-management program in addition to usual rehabilitation. The dose response of receiving the program cannot be ruled out, and the next stage of research should explore the feasibility of an integrated program. Exploration of the reasons behind relatively low recruitment and of the sensitivity of outcome measures to detect a change are also required. Additional investigation of intervention fidelity is required to monitor if the program is being delivered as intended. © 2013 The Authors.

This mixed-methods pilot study examined the feasibility, acceptability, and impact of a web-based gratitude exercise (the ‘Three Good Things’ exercise (TGT)) among 23 adults in outpatient treatment for alcohol use disorder (AUD). Participants were randomized to TGT or a placebo condition. The intervention was feasible with high rates of completion. Participants found TGT acceptable and welcomed the structure of daily emails; however, they found it difficult at times and discontinued TGT when the study ended. Participants associated TGT with gratitude, although there were no observed changes in grateful disposition over time. TGT had a significant effect on decreasing negative affect and increasing unactivated (e.g., feeling calm, at ease) positive affect, although there were no differences between groups at the 8 week follow up. Qualitative results converged on quantitative findings that TGT was convenient, feasible, and acceptable, and additionally suggested that TGT was beneficial for engendering positive cognitions and reinforcing recovery.

OBJECTIVE. To provide an example of an occupational therapy feasibility study and evaluate the implementation of a randomized controlled pilot and feasibility trial examining the impact of a sensory-adapted dental environment (SADE) to enhance oral care for children with autism spectrum disorder (ASD). METHOD. Twenty-two children with ASD and 22 typically developing children, ages 6–12 yr, attended a dental clinic in an urban hospital. Participants completed two dental cleanings, 3–4 mo apart, one in a regular environment and one in a SADE. Feasibility outcome measures were recruitment, retention, accrual, dropout, and protocol adherence. Intervention outcome measures were physiological stress, behavioral distress, pain, and cost. RESULTS. We successfully recruited and retained participants. Parents expressed satisfaction with research study participation. Dentists stated that the intervention could be incorporated in normal practice. Intervention outcome measures favored the SADE condition. CONCLUSION. Preliminary positive benefit of SADE in children with ASD warrants moving forward with a large-scale clinical trial. PMID:25871593

Objective Virtual reality (VR)-based cue reactivity has been successfully used for the assessment of drug craving. Going beyond assessment of cue reactivity, a novel VR-based treatment approach for smoking cessation was developed and tested for feasibility. Method In a randomized experiment, 10-week treatment feasibility trial, 46 nicotine-dependent adults, completed the10-week program. Virtual reality skills training (VRST) combined with nicotine replacement therapy (NRT) was compared to NRT alone. Participants were assessed for smoking behavior and coping skills during, at end of treatment, and at posttreatment follow-up. Results Smoking rates and craving for nicotine were significantly lower for the VRST group compared to NRT-only group at the end of treatment. Self-confidence and coping skills were also significantly higher for the VRST group, and number of cigarettes smoked was significantly lower, compared to the control group at follow-up. Conclusions Feasibility of VRST was supported in the current study. PMID:25484549

Clarithromycin may improve cachexia and survival in non-small cell lung cancer (NSCLC), but adequately controlled data are lacking. This study was undertaken primarily to inform the feasibility and scale of a phase III trial. Eligible consenting patients with stage IV NSCLC and cachexia were to be randomized to receive either clarithromycin 250mg twice daily or placebo for eight weeks. Aspects of trial feasibility recorded included numbers eligible, approached and recruited, together with adherence and completion of treatment and assessments. Over 6 months, none of 125 patients identified fulfilled the entry criteria. The commonest reasons for ineligibility were the use of an excluded concurrent drug (45, 36%), brain metastases (22, 18%), poor performance status (21, 17%) and current chemotherapy (15, 12%). A phase III trial of clarithromycin using these entry criteria is not feasible in this setting. Other macrolides that have a lower risk of a drug-drug interaction may be more practical to pursue.

Existing research evidence suggests that both music listening and mindfulness interventions may have beneficial effects on mood and cognition poststroke. This mixed-methods study, nested within a pilot randomized controlled trial investigating the feasibility and acceptability of combining music listening and brief mindfulness training poststroke, explored study participants' experiences of engaging in the interventions. Fifty-six stroke survivors who were randomized to receive an 8-week intervention of mindful music listening (n = 15), music listening (n = 21), or audiobook listening (n = 20, control) using self-selected material participated in a postintervention individual semistructured interview with a researcher not involved in their intervention delivery. Interview questions focused on affective, cognitive, and physical experiences. Data were coded and analyzed using thematic analysis. Across groups, listening was associated with positive distraction from thoughts and worries. Mindful music listening was most strongly associated with relaxation and concentration, improved attentional control, and emotion regulation, as well as enjoyment. Music listening was most strongly associated with increased activity, memory reminiscence, and improved mood. In addition, participants provided valuable feedback on intervention feasibility and acceptability. The findings suggest that the interventions were feasible and enjoyable for people recovering from stroke. © 2018 New York Academy of Sciences.

Subcutaneous port needle insertions are painful and distressing for children with cancer. The interactive MEDiPORT robot has been programmed to implement psychological strategies to decrease pain and distress during this procedure. This study assessed the feasibility of a future MEDiPORT trial. The secondary aim was to determine the preliminary effectiveness of MEDiPORT in reducing child pain and distress during subcutaneous port accesses. This 5-month pilot randomized controlled trial used a web-based service to randomize 4- to 9-year-olds with cancer to the MEDiPORT cognitive-behavioral arm (robot using evidence-based cognitive-behavioral interventions) or active distraction arm (robot dancing and singing) while a nurse conducted a needle insertion. We assessed accrual and retention; technical difficulties; outcome measure completion by children, parents, and nurses; time taken to complete the study and clinical procedure; and child-, parent-, and nurse-rated acceptability. Descriptive analyses, with exploratory inferential testing of child pain and distress data, were used to address study aims. Forty children were randomized across study arms. Most (85%) eligible children participated and no children withdrew. Technical difficulties were more common in the cognitive-behavioral arm. Completion times for the study and needle insertion were acceptable and >96% of outcome measure items were completed. Overall, MEDiPORT and the study were acceptable to participants. There was no difference in pain between arms, but distress during the procedure was less pronounced in the active distraction arm. The MEDiPORT study appears feasible to implement as an adequately-powered effectiveness-assessing trial following modifications to the intervention and study protocol.

Stress, depression, and anxiety affect 15% to 25% of pregnant women. However, substantial barriers to psychosocial assessment exist, resulting in less than 20% of prenatal care providers assessing and treating mental health problems. Moreover, pregnant women are often reluctant to disclose their mental health concerns to a healthcare provider. Identifying screening and assessment tools and procedures that are acceptable to both women and service providers, cost-effective, and clinically useful is needed. The primary objective of this randomized, parallel-group, superiority trial is to evaluate the feasibility and acceptability of a computer tablet-based prenatal psychosocial assessment (e-screening) compared to paper-based screening. Secondary objectives are to compare the two modes of screening on: (1) the level of detection of prenatal depression and anxiety symptoms and psychosocial risk; (2) the level of disclosure of symptoms; (3) the factors associated with feasibility, acceptability, and disclosure; (4) the psychometric properties of the e-version of the assessment tools; and (5) cost-effectiveness. A sample of 542 women will be recruited from large, primary care maternity clinics and a high-risk antenatal unit in an urban Canadian city. Pregnant women are eligible to participate if they: (1) receive care at one of the recruitment sites; (2) are able to speak/read English; (3) are willing to be randomized to e-screening; and (4) are willing to participate in a follow-up diagnostic interview within 1 week of recruitment. Allocation is by computer-generated randomization. Women in the intervention group will complete an online psychosocial assessment on a computer tablet, while those in the control group will complete the same assessment in paper-based form. All women will complete baseline questionnaires at the time of recruitment and will participate in a diagnostic interview within 1 week of recruitment. Research assistants conducting diagnostic interviews and physicians will be blinded. A qualitative descriptive study involving healthcare providers from the recruitment sites and women will provide data on feasibility and acceptability of the intervention. We hypothesize that mental health e-screening in primary care maternity settings and high-risk antenatal units will be as or more feasible, acceptable, and capable of detecting depression, anxiety, and psychosocial risk compared to paper-based screening.

To examine feasibility and initial efficacy of having previously treated parents serve as peer interventionists in family-based behavioral weight management treatment (FBT). Children aged 7-11 years with overweight/obesity and parents (n = 59 families) were enrolled in one of two pilot trials, the EPICH (Engaging Parents in Child Health) randomized trial comparing professional versus peer FBT delivery or the Parent Partnership trial, which provided professionally delivered FBT to families (first generation) and then randomly assigned first generation parents to either be or not be peer interventionists for subsequent families (second generation). Efficacy (child zBMI change), feasibility, and costs for delivering FBT, and impacts of being a peer interventionist were examined. In EPICH, families receiving professional versus peer intervention had similar decreases in child zBMI and parent BMI, with markedly lower costs for peer versus professional delivery. In Parent Partnership, families receiving peer intervention significantly decreased weight status, with very preliminary evidence suggesting better maintenance of child zBMI changes if parents served as peer interventionists. Previously treated parents were willing, highly confident, and able to serve as peer interventionists in FBT. Two pilot randomized clinical trials suggest parents-as-peer interventionists in FBT may be feasible, efficacious, and delivered at lower costs, with perhaps some additional benefits to serving as a peer interventionist. More robust investigation is warranted of peer treatment delivery models for pediatric weight management.

Introduction This randomized pilot trial evaluated two training modalities for first-line, evidence-based pediatric obesity services (screening and goal-setting) among nursing students. Method Participants (N=63) were randomized to Live Interactive Training (Live) or Web-facilitated Self-study Training (Web). Pre-training, post-training, and one-month follow-up assessments evaluated training feasibility, acceptability, and impact (knowledge, and skill via simulation). Moderator (previous experience) and predictor (content engagement) analyses were conducted. Results Nearly-all (98%) participants completed assessments. Both trainings were acceptable, with higher ratings for Live and participants with previous experience (p’s<.05). Knowledge and skill improved from pre-training to post-training and follow-up in both conditions (p’s<.001). Live demonstrated greater content engagement (p’s<.01). Conclusions The training package was feasible, acceptable, and efficacious among nursing students. Given that Live had higher acceptability and engagement, and online training offers greater scalability, integrating interactive Live components within Web-based training may optimize outcomes, which may enhance practitioners’ delivery of pediatric obesity services.

The feasibility and preliminary efficacy of an android robot-mediated mock job interview training in terms of both bolstering self-confidence and reducing biological levels of stress in comparison to a psycho-educational approach human interview was assessed in a randomized study. Young adults (ages 18–25 years) with autism spectrum disorder (ASD) were randomized to participate either in a mock job interview training with our android robot system (n = 7) or a self-paced review of materials about job-interviewing skills (n = 8). Baseline and outcome measurements of self-reported performance/efficacy and salivary cortisol were obtained after a mock job interview with a human interviewer. After training sessions, individuals with ASD participating in the android robot-mediated sessions reported marginally improved self-confidence and demonstrated significantly lower levels of salivary cortisol as compared to the control condition. These results provide preliminary support for the feasibility and efficacy of android robot-mediated learning. PMID:28955254

There has been growing interest in utilizing mobile phone applications (apps) to enhance traditional psychotherapy. Previous research has suggested that apps may facilitate patients' completion of cognitive behavioral therapy for insomnia (CBT-I) tasks and potentially increase adherence. This randomized clinical trial pilot study ( n = 18) sought to examine the feasibility, acceptability, and potential impact on adherence and sleep outcomes related to CBT-I Coach use. All participants were engaged in CBT-I, with one group receiving the app as a supplement and one non-app group. We found that patients consistently used the app as intended, particularly the sleep diary and reminder functions. They reported that it was highly acceptable to use. Importantly, the app did not compromise or undermine benefits of cognitive behavioral therapy for insomnia and patients in both groups had significantly improved sleep outcomes following treatment.

Purpose This study investigates the feasibility and potential utility of head-mounted displays for real-time wireless vital sign monitoring during surgical procedures. Methods In this randomized controlled pilot study, surgery residents (n = 14) performed simulated bedside procedures with traditional vital sign monitors and were randomized to addition of vital sign streaming to Google Glass. Time to recognition of preprogrammed vital sign deterioration and frequency of traditional monitor use was recorded. User feedback was collected by electronic survey. Results The experimental group spent 90% less time looking away from the procedural field to view traditional monitors during bronchoscopy (P = .003), and recognized critical desaturation 8.8 seconds earlier; the experimental group spent 71% (P = .01) less time looking away from the procedural field during thoracostomy, and recognized hypotension 10.5 seconds earlier. Trends toward earlier recognition of deterioration did not reach statistical significance. The majority of participants agreed that Google Glass increases situational awareness (64%), is helpful in monitoring vitals (86%), is easy to use (93%), and has potential to improve patient safety (85%). Conclusion In this early feasibility study, use of streaming to Google Glass significantly decreased time looking away from procedural fields and resulted in a nonsignificant trend toward earlier recognition of vital sign deterioration. Vital sign streaming with Google Glass or similar platforms is feasible and may enhance procedural situational awareness. © The Author(s) 2016.

To evaluate the feasibility and effectiveness of conducting a train-the-trainer (TTT) program for stable coronary artery disease (SCAD) management in community settings. The study involved two steps: (1) tutors trained community nurses as trainers and (2) the community nurses trained patients. 51 community nurses attended a 2-day TTT program and completed questionnaires assessing knowledge, self-efficacy, and satisfaction. By a feasibility and non-randomized control study, 120 SCAD patients were assigned either to intervention group (which received interventions from trained nurses) or control group (which received routine management). Pre- and post-intervention, patients' self-management behaviors and satisfaction were assessed to determine the program's overall impact. Community nurses' knowledge and self-efficacy improved (P<0.001), as did intervention group patients' self-management behaviors (P<0.001). The satisfaction of community nurses and patients was all very positive after training. The TTT program for SCAD management in community settings in China was generally feasible and effective, but many obstacles remain including patients' noncompliance, nurses' busy work schedules, and lack of policy supports. Finding ways to enhance the motivation of community nurses and patients with SCAD are important in implementing community-based TTT programs for SCAD management; further multicenter and randomized control trials are needed.

Transcranial direct current stimulation (tDCS) is a form of noninvasive brain stimulation that has shown improved adult stroke outcomes. Applying tDCS in children with congenital hemiparesis has not yet been explored. The primary objective of this study was to explore the safety and feasibility of single-session tDCS through an adverse events profile and symptom assessment within a double-blind, randomized placebo-controlled preliminary study in children with congenital hemiparesis. A secondary objective was to assess the stability of hand and cognitive function. A double-blind, randomized placebo-controlled pretest/posttest/follow-up study was conducted. The study was conducted in a university pediatric research laboratory. Thirteen children, ages 7 to 18 years, with congenital hemiparesis participated. Adverse events/safety assessment and hand function were measured. Participants were randomly assigned to either an intervention group or a control group, with safety and functional assessments at pretest, at posttest on the same day, and at a 1-week follow-up session. An intervention of 10 minutes of 0.7 mA tDCS was applied to bilateral primary motor cortices. The tDCS intervention was considered safe if there was no individual decline of 25% or group decline of 2 standard deviations for motor evoked potentials (MEPs) and behavioral data and no report of adverse events. No major adverse events were found, including no seizures. Two participants did not complete the study due to lack of MEP and discomfort. For the 11 participants who completed the study, group differences in MEPs and behavioral data did not exceed 2 standard deviations in those who received the tDCS (n=5) and those in the control group (n=6). The study was completed without the need for stopping per medical monitor and biostatisticial analysis. A limitation of the study was the small sample size, with data available for 11 participants. Based on the results of this study, tDCS appears to be safe, feasible, and well tolerated in most children with hemiparesis. Future investigations of serial sessions of tDCS in conjunction with rehabilitation in pediatric hemiparesis are indicated to explore the benefit of a synergistic approach to improving hand function. © 2015 American Physical Therapy Association.

Type 2 diabetes is a major health problem in many countries including India. Yoga may be an effective type 2 diabetes prevention strategy in India, particularly given its cultural familiarity. This was a parallel, randomized controlled pilot study to collect feasibility and preliminary efficacy data on yoga for diabetes risk factors among people at high risk of diabetes. Primary outcomes included: changes in BMI, waist circumference, fasting blood glucose, postprandial blood glucose, insulin, insulin resistance, blood pressure, and cholesterol. We also looked at measures of psychological well-being including changes in depression, anxiety, positive and negative affect and perceived stress. Forty-one participants with elevated fasting blood glucose in Bangalore, India were randomized to either yoga (n = 21) or a walking control (n = 20). Participants were asked to either attend yoga classes or complete monitored walking 3-6 days per week for eight weeks. Randomization and allocation was performed using computer-generated random numbers and group assignments delivered in sealed, opaque envelopes generated by off-site study staff. Data were analyzed based on intention to treat. This study was feasible in terms of recruitment, retention and adherence. In addition, yoga participants had significantly greater reductions in weight, waist circumference and BMI versus control (weight -0.8 ± 2.1 vs. 1.4 ± 3.6, p = 0.02; waist circumference -4.2 ± 4.8 vs. 0.7 ± 4.2, p < 0.01; BMI -0.2 ± 0.8 vs. 0.6 ± 1.6, p = 0.05). There were no between group differences in fasting blood glucose, postprandial blood glucose, insulin resistance or any other factors related to diabetes risk or psychological well-being. There were significant reductions in systolic and diastolic blood pressure, total cholesterol, anxiety, depression, negative affect and perceived stress in both the yoga intervention and walking control over the course of the study. Among Indians with elevated fasting blood glucose, we found that participation in an 8-week yoga intervention was feasible and resulted in greater weight loss and reduction in waist circumference when compared to a walking control. Yoga offers a promising lifestyle intervention for decreasing weight-related type 2 diabetes risk factors and potentially increasing psychological well-being.

Total hip replacement (THR) is a common elective surgical procedure and can be effective for reducing chronic pain. However, waiting times can be considerable. A pain self-management intervention may provide patients with skills to more effectively manage their pain and its impact during their wait for surgery. This study aimed to evaluate the feasibility of conducting a randomized controlled trial to assess the effectiveness and cost-effectiveness of a group-based pain self-management course for patients undergoing THR. Patients listed for a THR at one orthopedic center were posted a study invitation pack. Participants were randomized to attend a pain self-management course plus standard care or standard care only. The lay-led course was delivered by Arthritis Care and consisted of two half-day sessions prior to surgery and one full-day session after surgery. Participants provided outcome and resource-use data using a diary and postal questionnaires prior to surgery and one month, three months and six months after surgery. Brief telephone interviews were conducted with non-participants to explore barriers to participation. Invitations were sent to 385 eligible patients and 88 patients (23%) consented to participate. Interviews with 57 non-participants revealed the most common reasons for non-participation were views about the course and transport difficulties. Of the 43 patients randomized to the intervention group, 28 attended the pre-operative pain self-management sessions and 11 attended the post-operative sessions. Participant satisfaction with the course was high, and feedback highlighted that patients enjoyed the group format. Retention of participants was acceptable (83% of recruited patients completed follow-up) and questionnaire return rates were high (72% to 93%), with the exception of the pre-operative resource-use diary (35% return rate). Resource-use completion rates allowed for an economic evaluation from the health and social care payer perspective. This study highlights the importance of feasibility work prior to a randomized controlled trial to assess recruitment methods and rates, barriers to participation, logistics of scheduling group-based interventions, acceptability of the intervention and piloting resource use questionnaires to improve data available for economic evaluations.

The main objective of this pilot study was to explore the effect of chiropractic high-velocity, low-amplitude (HVLA) manipulation on vertical jump height in young female athletes with talocrural joint dysfunction. This was a randomized assessor-blind clinical pilot trial. Twenty-two female handball players with talocrural joint dysfunction were randomized to receive either HVLA manipulation (n = 11) or sham treatment (n = 11) once a week during a 3-week period. The main outcome was change in vertical jump height from baseline to follow-up within and between groups after 3 weeks. Nineteen athletes completed the study. After 3 weeks, the group receiving HVLA manipulation (n = 11) had a statistically significant mean (SD) improvement in vertical jump height of 1.07 (1.23) cm (P = .017). The sham treatment group (n = 8) improved their vertical jump height by 0.59 (2.03) cm (P = .436). The between groups' change was 0.47 cm (95% confidence interval, -1.31 to 2.26; P = .571) in favor of the group receiving HVLA manipulation. Blinding and sham procedures were feasible, and there were no reported adverse events. The results of this pilot study show that a larger-scale study is feasible. Preliminary results suggest that chiropractic HVLA manipulation may increase vertical jump height in young female athletes with talocrural joint dysfunction. However, the clinical result in favor of HVLA manipulation compared with sham treatment needs statistical confirmation in a larger randomized clinical trial.

Battlefield acupuncture (BFA) is an ear acupuncture protocol used by the military for immediate pain relief. This is a pilot feasibility study of BFA as a treatment for acute low back pain (LBP) in the emergency department (ED). Thirty acute LBP patients that presented to ED were randomized to standard care plus BFA or standard care alone. In the BFA group, outcomes were assessed at the time of randomization, 5 min after intervention, and again within 1 h after intervention. In the standard care group outcomes were assessed at the time of randomization and again an hour later. Primary outcomes included post-intervention LBP on a 10-point numeric pain rating scale (NRS) and the timed get-up-and-go test (GUGT). t-Test and chi squared tests were used to compare differences between groups demographics to evaluate randomization, and Analysis of Covariance (ANCOVA) was used to assess differences in primary/secondary outcomes. We randomized 15 patients to BFA plus standard care, and 15 patients to standard care alone. Demographics were similar between groups. Post-intervention LBP NRS was significantly lower in the BFA group compared with the standard care group (5.2 vs. 6.9, ANCOVA p = 0.04). GUGT was similar between groups (21.3 s vs. 19.0 s, ANCOVA p = 0.327). No adverse events from acupuncture were reported. This pilot study demonstrates that BFA is feasible as a therapy for LBP in the ED. Furthermore, our data suggest that BFA may be efficacious to improve LBP symptoms, and thus further efficacy studies are warranted. (Clinicaltrials.gov registration number NCT02399969).

In response to high burden of opioid abuse in Iran, Ministry of Health has launched a large-scale opioid maintenance treatment program, delivered through a network of certified drug treatment centers. To promote opioid pharmacotherapies, there is an urgent need to develop and introduce evidence-based psychosocial interventions into the network. This is a randomized clinical trial (RCT) to investigate feasibility and effectiveness of adding mindfulness-based group therapy to opioid pharmacotherapies as compared to opioid pharmacotherapies alone. The primary outcomes were treatment retention and percentage of weekly morphine, methamphetamine, and benzodiazepine negative tests. This is the first RCT that explores the effectiveness of mindfulness-based relapse prevention group therapy among opioid dependent clients in Iran. The feasibility of group therapy and comparison of outcomes in intervention and control groups should be discussed in the outcome article.

Background & objectives: Bone marrow mononuclear cell therapy has emerged as one of the option for the treatment of Stroke. Several preclinical studies have shown that the treatment with mononuclear cell (MNCs) can reduce the infarct size and improve the functional outcome. We evaluated the feasibility, safety and clinical outcome of administering bone marrow mononuclear cell (MNCs) intravenously to patients with subacute ischaemic stroke. Methods: In a non-randomized phase-I clinical study, 11 consecutive, eligible and consenting patients, aged 30-70 yr with ischaemic stroke involving anterior circulation within 7 to 30 days of onset of stroke were included. Bone marrow was aspirated from iliac crest and the harvested mononuclear cells were infused into antecubital vein. Outcomes measured for safety included immediate reactions after cell infusion and evidence of tumour formation at one year in whole body PET scan. Patients were followed at week 1, 4-6, 24 and 52 to determine clinical progress using National Institute of Health Stroke Scale (NIHSS), Barthel Index (BI), modified Rankin Scale (mRS), MRI, EEG and PET. Feasibility outcomes included target-dose feasibility. Favourable clinical outcome was defined as mRS score of 2 or less or BI score of 75 to 100 at six months after stem cell therapy. Results: Between September 2006 and April 2007, 11 patients were infused with bone-marrow mononuclear cells (mean 80 million with CD-34+ mean 0.92 million). Protocol was target-dose feasible in 9 patients (82%). FDG-PET scan at 24 and 52 wk in nine patients did not reveal evidence of tumour formation. Seven patients had favourable clinical outcome. Interpretation & conclusions: Intravenous bone marrow mononuclear cell therapy appears feasible and safe in patients with subacute ischaemic stroke. Further, a randomized controlled trial to examine its efficacy is being conducted. PMID:22960888

Vietnam is experiencing an epidemiologic transition with an increased prevalence of non-communicable diseases. Novel, large-scale, effective, and sustainable interventions to control hypertension in Vietnam are needed. We report the results of a cluster-randomized feasibility trial at 3 months follow-up conducted in Hung Yen province, Vietnam, designed to evaluate the feasibility and acceptability of two community-based interventions to improve hypertension control: a "storytelling" intervention, "We Talk about Our Hypertension," and a didactic intervention. The storytelling intervention included stories about strategies for coping with hypertension, with patients speaking in their own words, and didactic content about the importance of healthy lifestyle behaviors including salt reduction and exercise. The didactic intervention included only didactic content. The storytelling intervention was delivered by two DVDs at 3-month intervals; the didactic intervention included only one installment. The trial was conducted in four communes, equally randomized to the two interventions. The mean age of the 160 study patients was 66 years, and 54% were men. Most participants described both interventions as understandable, informative, and motivational. Between baseline and 3 months, mean systolic blood pressure declined by 8.2 mmHg (95% CI 4.1-12.2) in the storytelling group and by 5.5 mmHg (95% CI 1.4-9.5) in the didactic group. The storytelling group also reported a significant increase in hypertension medication adherence. Both interventions were well accepted in several rural communities and were shown to be potentially effective in lowering blood pressure. A large-scale randomized trial is needed to compare the effectiveness of the two interventions in controlling hypertension. ClinicalTrials.gov, NCT02483780.

A novel treatment, chewing gum, may be non-inferior to ondansetron in inhibiting postoperative nausea and vomiting (PONV) in female patients after laparoscopic or breast surgery. In this pilot study, we tested the feasibility of a large randomized controlled trial. We randomized 94 female patients undergoing laparoscopic or breast surgery to ondansetron 4 mg i.v. or chewing gum if PONV was experienced in the postanaesthesia care unit (PACU). The primary outcome was full resolution of PONV, with non-inferiority defined as a difference between groups of <15% in a per protocol analysis. Secondary outcomes were PACU stay duration, anti-emetic rescue use, and acceptability of anti-emetic treatment. The feasibility of implementing the protocol in a larger trial was assessed. Postoperative nausea and vomiting in the PACU occurred in 13 (28%) ondansetron patients and 15 (31%) chewing gum patients (P=0.75). Three chewing gum patients could not chew gum when they developed PONV. On a per protocol basis, full resolution of PONV occurred in five of 13 (39%) ondansetron vs nine of 12 (75%) chewing gum patients [risk difference 37% (6.3-67%), P=0.07]. There was no difference in secondary outcomes between groups. Recruitment was satisfactory, the protocol was acceptable to anaesthetists and nurses, and data collection was complete. In this pilot trial, chewing gum was not inferior to ondansetron for treatment of PONV after general anaesthesia for laparoscopic or breast surgery in female patients. Our findings demonstrate the feasibility of a larger, multicentred randomized controlled trial to investigate this novel therapy.

We conducted a pilot randomized clinical trial of office-based active vision therapy for the treatment of childhood amblyopia to determine the feasibility of conducting a full-scale randomized clinical trial. A training and certification program and manual of procedures were developed to certify therapists to administer a standardized vision therapy program in ophthalmology and optometry offices consisting of weekly visits for 16 weeks. Nineteen children, aged 7 to less than 13 years, with amblyopia (20/40-20/100) were randomly assigned to receive either 2 hours of daily patching with active vision therapy or 2 hours of daily patching with placebo vision therapy. Therapists in diverse practice settings were successfully trained and certified to perform standardized vision therapy in strict adherence with protocol. Subjects completed 85% of required weekly in-office vision therapy visits. Eligibility criteria based on age, visual acuity, and stereoacuity, designed to identify children able to complete a standardized vision therapy program and judged likely to benefit from this treatment, led to a high proportion of screened subjects being judged ineligible, resulting in insufficient recruitment. There were difficulties in retrieving adherence data for the computerized home therapy procedures. This study demonstrated that a 16-week treatment trial of vision therapy was feasible with respect to maintaining protocol adherence; however, recruitment under the proposed eligibility criteria, necessitated by the standardized approach to vision therapy, was not successful. A randomized clinical trial of in-office vision therapy for the treatment of amblyopia would require broadening of the eligibility criteria and improved methods to gather objective data regarding the home therapy. A more flexible approach that customizes vision therapy based on subject age, visual acuity, and stereopsis might be required to allow enrollment of a broader group of subjects.

South Africa recently phased out access to free formula milk in the public sector in support of breastfeeding for women living with HIV. Few women living with HIV in South Africa choose breastfeeding and among those who do, many stop breastfeeding early. We sought to explore the feasibility of using mobile phone text messaging coupled with motivational interviewing to enhance adherence to breastfeeding practices. A randomized, parallel group, single-center pilot trial. Electronic sequence generation and random allocation will be done centrally. Women of low socioeconomic status, from Cape Town, South Africa will be randomly assigned within 24 h of giving birth at a primary healthcare clinic to a structured weekly text message plus motivational interviewing and usual standard of care, using a permutation of different block sizes. Criteria for feasibility success will include: five participants recruited per week (over 12 weeks), about 75% of all eligible participants consent for study participation, complete evaluation of outcomes in at least 70% of all recruited participants, breastfeeding adherence rates of at least 70% in the intervention group, six months after delivery. Participants will be evaluated soon after giving birth and post-delivery at weeks 2, 6, 10, and 24. Primary analysis will follow the "intention-to-treat" principle. Sub-group analysis will be used to assess sub-group effects. This pilot trial will evaluate the feasibility of conducting a larger trial on communication and support approaches to improve adherence to breastfeeding by HIV-infected women. Text messaging and motivational interviewing are simple interventions which may allow participants to access personalized adherence advice and support. ClinicalTrials.gov: NCT02949713 .

Background There are high rates of treatment non-completion for personality disorder and those who do not complete treatment have poorer outcomes. A goal-based motivational interview may increase service users’ readiness to engage with therapy and so enhance treatment retention. We conducted a feasibility study to inform the design of a randomized controlled trial. The aims were to test the feasibility of recruitment, randomization and follow-up, and to conduct a preliminary evaluation of the effectiveness of the motivational interview. Methods Patients in an outpatient personality disorder service were randomized to receive the Personal Concerns Inventory plus treatment as usual or treatment as usual only. The main randomized controlled trial feasibility criteria were recruitment of 54% of referrals, and 80% of clients and therapists finding the intervention acceptable. Information was collected on treatment attendance, the clarity of therapy goals and treatment engagement. Results The recruitment rate was 29% (76 of 258). Of 12 interviewed at follow-up, eight (67%) were positive about the Personal Concerns Inventory. Pre-intervention interviews were conducted with 61% (23 out of 38) of the Personal Concerns Inventory group and 74% (28 out of 38) of the treatment as usual group. Participants’ therapy goals were blind-rated for clarity on a scale of 0 to 10. The mean score for the Personal Concerns Inventory group was 6.64 (SD = 2.28) and for the treatment as usual group 2.94 (SD = 1.71). Over 12 weeks, the median percentage session attendance was 83.33% for the Personal Concerns Inventory group (N = 17) and 66.67% for the treatment as usual group (N = 24). Of 59 eligible participants at follow-up, the Treatment Engagement Rating scale was completed for 40 (68%). The mean Treatment Engagement Rating scale score for the Personal Concerns Inventory group was 6.64 (SD = 2.28) and for the treatment as usual group 2.94 (SD = 1.71). Of the 76 participants, 63 (83%) completed the Client Service Receipt Inventory at baseline and 34 of 59 (58%) at follow-up. Conclusion Shortfalls in recruitment and follow-up data collection were explained by major changes to the service. However, evidence of a substantial positive impact of the Personal Concerns Inventory on treatment attendance, clarity of therapy goals and treatment engagement, make a full-scale evaluation worth pursuing. Further preparatory work is required for a multisite trial. Trial registration ClinicalTrials.Gov.UK Identifier - NCT01132976 PMID:23414174

Ketorolac, a NSAID routinely used during surgery proposed to have anticancer effects, is a promising way to improve postoperative oncological outcome. This effect may be particularly prominent in patients with elevated preoperative inflammatory scores, like the neutrophil:lymphocyte ratio. In this paper, we describe the rationale, the preliminary analyses in our patients, the feasibility and the methodology of a prospective randomized trial called "Ketorolac in Breast Cancer trial" (KBCt) (NCT01806259).

In order to move towards rational drug use in any national or local setting the methods of inquiry have to be expanded. Both the public and private sector have to be addressed. In the latter the pharmacists might be studied using a tracer, fictitious client. One important factor influencing prescribing, drug information, has rarely been assessed scientifically. Experimental studies using group randomization are, however feasible even in developing countries. The individual human being must be in the focus of drug studies and health care and health in the foreground. The combination of qualitative and quantitative methods will assist us to achieve rational drug use that is culturally acceptable, economically feasible and pharmacologically sound.

Objective Although adiposity has been considered protective against hot flashes, newer data suggest positive relations between flashes and adiposity. No studies have been specifically designed to test whether weight loss reduces hot flashes. This pilot study aimed to evaluate the feasibility, acceptability, and initial efficacy of behavioral weight loss to reduce hot flashes. Methods Forty overweight/obese women with hot flashes (≥4/day) were randomized to a behavioral weight loss intervention or to wait list control. Hot flashes were assessed pre- and post-intervention via physiologic monitor, diary, and questionnaire. Comparisons of changes in hot flashes and anthropometrics between conditions were tested via Wilcoxon tests. Results Study retention (83%) and intervention satisfaction (93.8%) were high. Most women (74.1%) reported that hot flash reduction was a main motivator to lose weight. Women randomized to the weight loss intervention lost more weight (-8.86 kg) than did women randomized to control (+0.23 kg, p<.0001). Women randomized to weight loss also showed greater reductions in questionnaire-reported hot flashes (2-week hot flashes: −63.0) than did women in the control (−28.0, p=.03), a difference not demonstrated in other hot flash measures. Reductions in weight and hot flashes were significantly correlated (e.g., r=.47, p=.006). Conclusions This pilot study showed a behavioral weight loss program to be feasible, acceptable, and effective in producing weight loss among overweight/obese women with hot flashes. Findings indicate the importance of a larger study designed to test behavioral weight loss for hot flash reduction. Hot flash management could motivate women to engage in this health-promoting behavior. PMID:24977456

The 15- to 35-year-old population has little contact with the health care system and is exposed to risk factors. Several studies demonstrated the feasibility of brief interventions (BIs) in different settings, e.g., in addiction medicine during police custody, where arrestees are entitled to a medical examination. Approximately 700,000 individuals are detained in police custody in France annually, and custody is an opportunity for young people to be medically examined. The characteristics of the detainees and previous experience with BIs suggest that custody is an opportunity to contribute to primary prevention. We propose to investigate the feasibility of such a contribution. The aim of this article is to present a study protocol and some preliminary results. The primary research objective is to assess the feasibility of performing brief interventions without a specific topic in police custody settings in arrestees aged 15-35 years. The secondary research objectives include i) testing four strategies for engaging in BIs that maximize the chances of success of the BI; ii) identifying the determinants that can orient the practitioner's choice to use a specific strategy over another one; and iii) analysing the differences between individuals who engage in BIs and those who do not and, in those who do engage, the determinants of success of the intervention. A two-step randomized and prospective study: i) randomization of eligible patients into 4 groups of 500 patients each; analysis of the response rates for each strategy; performance of the BI; and analyses of the associated factors and ii) a real-life, full-scale phase study evaluating the effectiveness of BIs performance of the BI; and analyses of the interventions. Analyses of the determinants of a positive response to BI, of success and of the topic of intervention will be conducted. The rates of BI performed, rates of success, and characteristics associated with response and with success are the main expected results. Additionally, the development and assessment of filter questions and an improved BI dedicated to primary prevention for police custody settings will be attained.

To evaluate the feasibility and safety of home rehabilitation of the hand using a robotic glove, and, in addition, its effectiveness, in hemiplegic patients after stroke. In this non-randomized pilot study, 21 hemiplegic stroke patients (Ashworth spasticity index ≤ 3) were prescribed, after in-hospital rehabilitation, a 2-month home-program of intensive hand training using the Gloreha Lite glove that provides computer-controlled passive mobilization of the fingers. Feasibility was measured by: number of patients who completed the home-program, minutes of exercise and number of sessions/patient performed. Safety was assessed by: hand pain with a visual analog scale (VAS), Ashworth spasticity index for finger flexors, opponents of the thumb and wrist flexors, and hand edema (circumference of forearm, wrist and fingers), measured at start (T0) and end (T1) of rehabilitation. Hand motor function (Motricity Index, MI), fine manual dexterity (Nine Hole Peg Test, NHPT) and strength (Grip test) were also measured at T0 and T1. Patients performed, over a mean period 56 (49-63) days, a total of 1699 (1353-2045) min/patient of exercise with Gloreha Lite, 5.1 (4.3-5.8) days/week. Seventeen patients (81%) completed the full program. The mean VAS score of hand pain, Ashworth spasticity index and hand edema did not change significantly at T1 compared to T0. The MI, NHPT and Grip test improved significantly (p = 0.0020, 0.0156 and 0.0024, respectively) compared to baseline. Gloreha Lite is feasible and safe for use in home rehabilitation. The efficacy data show a therapeutic effect which need to be confirmed by a randomized controlled study.

Although individuals with psychiatric disorders are disproportionately affected by cigarette smoking, few outpatient mental health treatment facilities offer smoking cessation services. In this paper, we describe the development of a smartphone-assisted mindfulness smoking cessation intervention with contingency management (SMI-CM), as well as the design and methods of an ongoing pilot randomized controlled trial (RCT) targeting smokers receiving outpatient psychiatric treatment. We also report the results of an open-label pilot feasibility study. In phase 1, we developed and pilot-tested SMI-CM, which includes a smartphone intervention app that prompts participants to practice mindfulness, complete ecological momentary assessment (EMA) reports 5 times per day, and submit carbon monoxide (CO) videos twice per day. Participants earned incentives if submitted videos showed CO≤6ppm. In phase 2, smokers receiving outpatient treatment for mood disorders are randomized to receive SMI-CM or enhanced standard treatment plus non-contingent CM (EST). The results from the pilot feasibility study (N=8) showed that participants practiced mindfulness an average of 3.4times/day (≥3min), completed 72.3% of prompted EMA reports, and submitted 68.0% of requested CO videos. Participants reported that the program was helpful overall (M=4.85/5) and that daily mindfulness practice was helpful for both managing mood and quitting smoking (Ms=4.50/5). The results from the feasibility study indicated high levels of acceptability and satisfaction with SMI-CM. The ongoing RCT will allow evaluation of the efficacy and mechanisms of action underlying SMI-CM for improving cessation rates among smokers with mood disorders. Copyright © 2017 Elsevier Inc.

Music has the potential to be an effective and engaging therapeutic intervention in the treatment of mental illness. This research area remains underdeveloped. This paper reports the feasibility of an innovative low-intensity CBT-based music (CBT-Music) group targeted to symptoms of depression and anxiety. A total of 28 participants with symptoms of depression and anxiety who were attending community mental health services were recruited for the study and randomized into TAU (treatment as usual) plus low-intensity CBT-Music (treatment) or to TAU alone (control). The treatment group consisted of a 9-week music group that incorporated various components of CBT material into a musical context. Feasibility was the primary outcome. The secondary outcomes were a reduction in depression, anxiety (Hospital Anxiety and Depression Scale) and disability (WHO Disability Assessment Schedule 2.0) assessed at baseline and 10 weeks. Recruitment proved feasible, retention rates were high, and the participants reported a high level of acceptability. A randomized control study design was successfully implemented as there were no significant differences between treatment and control groups at baseline. Participants in the treatment group showed improvement in disability (p = 0.027). Despite a reduction in depression and anxiety scores, these differences were not statistically significant. A low-intensity CBT-based music group can be successfully administered to clients of community mental health services. There are indications of effectiveness in reducing disability, although there appears to be negligible effect on symptoms of anxiety and depression. This is the first report of a trial of a low-intensity CBT-based music group intervention.

Despite the increasing prevalence of mental health disorders in university students, few receive needed evidence-based treatment. The purpose of this study was to assess the feasibility and preliminary effects of a seven-session online cognitive-behavioral skill-building intervention (i.e., COPE, Creating Opportunities for Personal Empowerment) versus a comparison group on their anxiety, depressive symptoms, and grade performance. A randomized controlled pilot study was conducted from September 2012 to May 2013 with 121 college freshmen enrolled in a required one credit survey course. Although there were no significant differences in anxiety and depressive symptoms between the groups, only COPE students with an elevated level of anxiety at baseline had a significant decline in symptoms. Grade point average was higher in COPE versus comparison students. Evaluations indicated that COPE was a positive experience for students. COPE is a promising brief intervention that can be integrated effectively into a required freshman course. © 2015 Wiley Periodicals, Inc.

The feasibility of magnetic resonance venography (MRV) for measuring change in thrombus volume with a novel anticoagulation regimen versus standard anticoagulation in patients with symptomatic deep vein thrombosis (DVT) has not been assessed. Our aim was to study the feasibility of MRV to measure change in thrombus volume in patients with acute symptomatic objectively confirmed proximal DVT in an open-label multicenter trial (edoxaban Thrombus Reduction Imaging Study, eTRIS). We randomized patients in a 2:1 allocation ratio to edoxaban 90 mg/day for 10 days followed by 60 mg/day versus parenteral anticoagulation bridging to warfarin for 3 months. The primary efficacy outcome was a surrogate end point of the relative change in MRV-quantified thrombus volume from baseline to Day 14-21. A total of 85 eligible patients from 26 study sites were randomized to edoxaban monotherapy (n=56) versus parenteral anticoagulation as a 'bridge' to warfarin (n=29). The mean relative change in MRV-quantified thrombus volume from baseline to Day 14-21 was similar in patients treated with edoxaban and parenteral anticoagulation as a 'bridge' to warfarin (-50.1% vs -58.9%; 95% confidence interval of treatment difference, -12.7%, 30.2%). However, thrombus extension was observed in eight patients in the edoxaban monotherapy group and in none in the warfarin group. Rates of recurrent venous thromboembolism (3.6% vs 3.6%, p=0.45) and clinically relevant non-major bleeding (5.4% vs 7.1%, p=0.34) were also similar. No major bleeds occurred in either on-treatment group during the study period. In conclusion, MRV can assess change in thrombus volume in patients with acute DVT randomized to two different anticoagulant regimens.ClinicalTrials.gov IDENTIFIER NCT01662908: INVESTIGATIONAL NEW DRUG IND APPLICATION EDOXABAN IND # 63266. © The Author(s) 2016.

Setting: A community health clinic catchment area in the eastern part of Bandung City, Indonesia. Objective: To evaluate the feasibility of two different screening interventions using community health workers (CHWs) in detecting tuberculosis (TB) cases. Design: This was a feasibility study of 1) house-to-house TB symptom screening of five randomly selected 'neighbourhoods' in the catchment area, and 2) selected screening of household contacts of TB index patients and their neighbouring households. Acceptability was assessed through focus group discussions with key stakeholders. Results: Of 5100 individuals screened in randomly selected neighbourhoods, 48 (0.9%) reported symptoms, of whom 38 provided sputum samples; no positive TB was found. No TB cases were found among the 88 household contacts or the 423 neighbourhood contacts. With training, regular support and supervision from research staff and local community health centre staff, CHWs were able to undertake screening effectively, and almost all householders were willing to participate. Conclusion: The use of CHWs for TB screening could be integrated into routine practice relatively easily in Indonesia. The effectiveness of this would need further exploration, particularly with the use of improved diagnostics such as chest X-ray and sputum culture.

Adolescents with cancer experience many troubling symptoms, including sleep disruptions that can affect mood and quality of life. Massage is a safe and popular intervention that has demonstrated efficacy in pediatric and adult patients with cancer. This study aimed to assess the feasibility of conducting a massage intervention to help with sleep in hospitalized adolescent oncology patients. Adolescents ages 12-21 with cancer who were expected to be hospitalized for at least four consecutive nights were recruited from the inpatient unit at Children's National Health System and randomized to either massage intervention or a waitlist control. Patients in the intervention group received one massage per night, for two or three nights. Sleep was measured with actigraphy and patient and proxy reported instruments were used to measure fatigue, mood, and anxiety. The majority (78%) of patients approached for the study consented, and almost all patients in the intervention group (94%) received at least one massage, 69% received two, and rates of completion of instruments among adolescents were high demonstrating feasibility. There were trends toward increased night time and overall sleep in the intervention group compared with standard of care, but no differences between groups in the patient reported outcome measures. Participant and parent feedback on the intervention was positive and was the impetus for starting a clinical massage service at the hospital. Massage for hospitalized adolescents with cancer is feasible, well received, and can potentially improve patients' sleep. A randomized multicenter efficacy study is warranted. © 2016 Wiley Periodicals, Inc.

Public health researchers are addressing new research questions (e.g., effects of environmental tobacco smoke, Hurricane Katrina) for which the randomized controlled trial (RCT) may not be a feasible option. Drawing on the potential outcomes framework (Rubin Causal Model) and Campbellian perspectives, we consider alternative research designs that permit relatively strong causal inferences. In randomized encouragement designs, participants are randomly invited to participate in one of the treatment conditions, but are allowed to decide whether to receive treatment. In quantitative assignment designs, treatment is assigned on the basis of a quantitative measure (e.g., need, merit, risk). In observational studies, treatment assignment is unknown and presumed to be nonrandom. Major threats to the validity of each design and statistical strategies for mitigating those threats are presented. PMID:18556609

Despite an intensive search for predictors of the response to cardiac resynchronization therapy (CRT), the QRS duration remains the simplest and most robust predictor of a positive response. QRS duration of ≥ 130 ms is considered to be a prerequisite for CRT; however, some studies have shown that CRT may also be effective in heart failure (HF) patients with a narrow QRS (<130 ms). Since CRT can now be performed by pacing the left ventricle from multiple vectors via a single quadripolar lead, it is possible that multipoint pacing (MPP) might be effective in HF patients with a narrow QRS. This article reports the design of the MPP Narrow QRS trial, a prospective, randomized, multicenter, controlled feasibility study to investigate the efficacy of MPP using two LV pacing vectors in patients with a narrow QRS complex (100-130 ms). Fifty patients with a standard ICD indication will be enrolled and randomized (1:1) to either an MPP group or a Standard ICD group. All patients will undergo a low-dose dobutamine stress echo test and only those with contractile reserve will be included in the study and randomized. The primary endpoint will be the percentage of patients in each group that have reverse remodeling at 12 months, defined as a reduction in left ventricular end-systolic volume (LVESV) of >15% from the baseline. This feasibility study will determine whether MPP improves reverse remodeling, as compared with standard ICD, in HF patients who have a narrow QRS complex (100-130 ms).

Comparative effectiveness research in cancer with observational data.
Giordano, Sharon H
2015-01-01
Observational studies are increasingly being used for comparative effectiveness research. These studies can have the greatest impact when randomized trials are not feasible or when randomized studies have not included the population or outcomes of interest. However, careful attention must be paid to study design to minimize the likelihood of selection biases. Analytic techniques, such as multivariable regression modeling, propensity score analysis, and instrumental variable analysis, also can also be used to help address confounding. Oncology has many existing large and clinically rich observational databases that can be used for comparative effectiveness research. With careful study design, observational studies can produce valid results to assess the benefits and harms of a treatment or intervention in representative real-world populations.

Psychosocial interventions for patients with chronic hepatitis C viral (HCV) infection are needed to attenuate the impact of extrahepatic symptoms, comorbid conditions, and treatment side effects on HCV health outcomes. We adapted empirically-supported interventions for similar patient populations to develop a Cognitive Behavioral Coping Skills group intervention for HCV patients (CBCS-HCV) undergoing treatment. The objectives of this paper are to describe the research activities associated with CBCS-HCV development and pilot testing, including: (1) formative work leading to intervention development; (2) preliminary study protocol; and (3) pilot feasibility testing of the intervention and study design. Formative work included a literature review, qualitative interviews, and adaption, development, and review of study materials. A preliminary study protocol is described. We evaluate the feasibility of conducting a randomized controlled trial (RCT) of the CBCS-HCV with 12 study participants in Wave 1 testing to examine: (a) feasibility of intervention delivery; (b) patient acceptability; (c) recruitment, enrollment, retention; (d) feasibility of conducting a RCT; (d) therapist protocol fidelity; and (e) feasibility of data collection. Numerous lessons were learned. We found very high rates of data collection, participant attendance, engagement, retention and acceptability, and therapist protocol fidelity. We conclude that many aspects of the CBCS-HCV intervention and study protocol were highly feasible. The greatest challenge during this Wave 1 pilot study was efficiency of participant enrollment due to changes in standard of care treatment. These findings informed two additional waves of pilot testing to examine effect sizes and potential improvements in clinical outcomes, with results forthcoming.

Abstract Background and Aims Naloxone is an opioid antagonist used for emergency resuscitation following opioid overdose. Prisoners with a history of heroin injection have a high risk of drug‐related death soon after release from prison. The NALoxone InVEstigation (N‐ALIVE) pilot trial (ISRCTN34044390) tested feasibility measures for randomized provision of naloxone‐on‐release (NOR) to eligible prisoners in England. Design. Parallel‐group randomized controlled pilot trial. Setting English prisons. Participants A total of 1685 adult heroin injectors, incarcerated for at least 7 days pre‐randomization, release due within 3 months and more than 6 months since previous N‐ALIVE release. Intervention Using 1 : 1 minimization, prisoners were randomized to receive on release a pack containing either a single ‘rescue’ injection of naloxone or a control pack with no syringe. Measurements Key feasibility outcomes were tested against prior expectations: on participation (14 English prisons; 2800 prisoners), consent (75% for randomization), returned prisoner self‐questionnaires (RPSQs: 207), NOR‐carriage (75% in first 4 weeks) and overdose presence (80%). Findings Prisons (16) and prisoners (1685) were willing to participate [consent rate, 95% confidence interval (CI) = 70–74%]; 218 RPSQs were received; NOR‐carriage (95% CI = 63–79%) and overdose presence (95% CI = 75–84%) were as expected. We randomized 842 to NOR and 843 to control during 30 months but stopped early, because only one‐third of NOR administrations were to the ex‐prisoner. Nine deaths within 12 weeks of release were registered for 1557 randomized participants released before 9 December 2014. Conclusions Large randomized trials are feasible with prison populations. Provision of take‐home emergency naloxone prior to prison release may be a life‐saving interim measure to prevent heroin overdose deaths among ex‐prisoners and the wider population. PMID:27776382

Purpose We designed and evaluated for feasibility an intervention - Yo Puedo - that addresses social network influences and socioeconomic opportunities in a neighborhood with substantial gang exposure and early childbearing. Methods Yo Puedo combined conditional cash transfers for completion of educational and reproductive health wellness goals with life skills sessions, and targeted youth 16 to 21 years old and same-aged members of their social network. We conducted a 2-arm study with social networks randomized to the intervention or a standard services control arm. We evaluated intervention uptake, adherence and safety; and assessed evidence of effects on behavioral outcomes associated with unintended pregnancy and STI risk. Results Seventy-two social networks comprised of 162 youth enrolled, with 92% retention over six months. Seventy-two percent of youth randomized to the intervention participated in intervention activities: 53% received at least one CCT payment; and 66% came to at least one life skills session. We found no evidence that cash payments financed illicit or high-risk behavior. At six months, intervention participants, compared to controls, had a lower odds of hanging out on the street frequently (OR = 0.54, p = 0.10) and a lower odds of reporting their close friends had been incarcerated (OR = 0.6, p=0.12). They reported less regular alcohol use (OR = 0.54, p=0.04) and a lower odds of having sex (OR = 0.50, p = 0.04). Conclusions The feasibility evaluation of Yo Puedo demonstrated its promise; a larger evaluation of effects on pregnancy and sustained behavioral changes is warranted. PMID:24518532

Seventy-two percent of youth randomized to the intervention participated in intervention activities: 53% received at least one conditional cash transfer payment and 66% came to at least one life skills session. We found no evidence that cash payments financed illicit or high-risk behavior. At 6 months, compared with controls, intervention participants had a lower odds of hanging out on the street frequently (odds ratio [OR], .54; p = .10) and a lower odds of reporting that their close friends had been incarcerated (OR, .6; p = .12). They reported less regular alcohol use (OR, .54; p = .04) and a lower odds of having sex (OR, .50; p = .04). The feasibility evaluation of Yo Puedo demonstrated its promise; a larger evaluation of effects on pregnancy and sustained behavioral changes is warranted.

A randomized control pilot study was conducted with Black men who have sex with men (BMSM; N = 42) aged 18-30 years to examine the feasibility of implementing a video intervention delivered using Facebook to motivate HIV testing. At baseline, participants were unaware of their HIV status and had not tested for HIV in the past 6 months, residing in Los Angeles County. The intervention content included topics such as social influence, HIV knowledge, stigma, HIV positive knowledge, and benefits of knowing one's HIV status. Logistic regression revealed that those receiving the video intervention were 7 times more likely to have tested for HIV than those in the control group at 6-week follow-up (odds ratio [ OR ] = 7.00, 95% confidence interval [1.72, 28.33], p = .006). Data suggest that the intervention was feasible for motivating HIV testing.

This study assessed the feasibility of a 12-week program of exercise, with and without intramuscular testosterone supplementation, in male patients with chronic heart failure (CHF) and low testosterone status and collected preliminary data for key health outcomes. Male patients with CHF (n = 41, age 67.2 years, range 51-84 years) with mean ± SD testosterone levels of 10.7 ± 2.6 nmol/L (309 ± 76 ng/dL) were randomly allocated to exercise with testosterone or placebo groups. Feasibility was assessed in terms of recruitment, intervention compliance, and attrition. Outcomes included an incremental shuttle walk test, peak oxygen uptake, muscular strength, echocardiographic measures, N-terminal pro-brain natriuretic peptide, inflammatory markers, depression (Beck Depression Inventory), and health-related quality of life (Minnesota Living with Heart Failure Questionnaire and Medical Outcomes Study Short-Form). Attrition was 30% but with 100% compliance to exercise and injections in patients who completed the study. Similar improvements in shuttle walk test (18% vs 19%), body mass (-1.3 kg vs -1.0 kg), and hand grip strength (2.1 kg vs 2.5 kg) from baseline were observed in both groups. The exercise with testosterone group showed improvements from baseline in peak oxygen uptake (P < .01), Beck Depression Inventory (P < .05), leg strength (P < .05), and several Medical Outcomes Study Short-Form quality of life domains (P < .05), which were generally not apparent in the exercise with placebo group. Echocardiographic measures, N-terminal pro-brain natriuretic peptide, and inflammatory markers were mostly unchanged. This study shows for the first time that testosterone supplementation during a program of exercise rehabilitation is feasible and can positively impact on a range of key health outcomes in elderly male patients with CHF who have a low testosterone status.

We examined the feasibility of a combined aerobic and strength training program in institutionalized dementia patients and studied the effects on cognitive and physical function. Thirty-three patients with dementia, recruited from one nursing home, participated in this non-randomized pilot study (25 women; age = 85.2±4.9 years; Mini Mental State Examination = 16.8±4.0). In phase 1 of the study, seventeen patients in the Exercise group (EG) received a combined aerobic and strength training program for six weeks, five times per week, 30 minutes per session, in an individually supervised format and successfully concluded the pre and posttests. In phase 2 of the study, sixteen patients in the Social group (SG) received social visits at the same frequency, duration, and format and successfully concluded the pre and posttests. Indices of feasibility showed that the recruitment and adherence rate, respectively were 46.2% and 86.3%. All EG patients completed the exercise program according to protocol without adverse events. After the six-week program, no significant differences on cognitive function tests were found between the EG and SG. There was a moderate effect size in favor for the EG for the Visual Memory Span Forward; a visual attention test. There were significant differences between groups in favor for the EG with moderate to large effects for the physical tests Walking Speed (p = .003), Six-Minute Walk Test (p = .031), and isometric quadriceps strength (p = .012). The present pilot study showed that it is feasible to conduct a combined aerobic and strength training program in institutionalized patients with dementia. The selective cognitive visual attention improvements and more robust changes in motor function in favor of EG vs. SG could serve as a basis for large randomized clinical trials. trialregister.nl 1230.
Training Endogenous Task Shifting Using Music Therapy: A Feasibility Study.
Lynch, Colleen; LaGasse, A Blythe

People with acquired brain injury (ABI) are highly susceptible to disturbances in executive functioning (EF), and these effects are pervasive. Research studies using music therapy for cognitive improvement in this population are limited. The purpose of this study was to determine the feasibility of a Musical Executive Function Training (MEFT) intervention to address task-shifting skills in adults with ABI and to obtain preliminary evidence of intervention effect on task shifting. Fourteen participants were randomly assigned to one of three groups: a music therapy intervention group (MTG), a singing group (SG), or the no-intervention control group (CG). The SG and MTG met for one hour a day for five days. Feasibility measures included participant completion rates and intervention fidelity. Potential benefits were measured using the Trail Making Test and the Paced Auditory Serial Addition Task as a pre- and posttest measure. Participant completion rates and interventionist fidelity to the protocol supported feasibility. One-way ANOVA of the pre- and posttest group differences revealed a trend toward improvement in the MTG over the SG. Feasibility and effect size data support a larger trial of the MEFT protocol. © the American Music Therapy Association 2016. All rights reserved.

Benefits of art participation after stroke are becoming increasingly recognized. Qualitative studies suggest that participation in visual arts creative engagement interventions (CEIs) during rehabilitation after stroke may improve mood, self-esteem, hope and some aspects of physical recovery. This study examines the feasibility of undertaking a randomized controlled trial of a CEI delivered by artists within in-patient stroke rehabilitation to test effectiveness. This trial is a two arm, single-blind, randomized controlled feasibility trial within in-patient stroke rehabilitation. We will recruit 80 patients receiving stroke rehabilitation in two stroke units in a health board area of Scotland (40 patients in each arm). Intervention arm participants will receive a visual-arts based CEI facilitated by experienced artists. Artists will follow an intervention protocol with specific components that enable participants to set, achieve and review artistic goals. Participants will receive up to eight intervention sessions, four within a group and four one-to-one with the artist. Control group participants will receive usual care only.Data collection will occur at baseline, post-intervention and three-month follow-up. Stroke-related health status is the primary outcome; mood, self-esteem, self-efficacy, perceived recovery control and hope are secondary outcomes. Semi-structured interviews will be conducted with purposively selected patients, artists and healthcare staff to elicit views and experiences of the intervention and feasibility and acceptability of trial processes. Recruitment rates, retention rates and patient preference for art participation will also be collected. Data will indicate, with confidence intervals, the proportion of patients choosing or refusing participation in the CEI and will allow calculation of recruitment rates for a future definitive trial. Summary data will indicate potential variability, magnitude and direction of difference between groups. Findings will inform sample size calculations for a definitive trial. Thematic analysis of qualitative data will be managed using the Framework Approach. Framework is an analytical approach for qualitative data, commonly used in policy and medical research. If shown to demonstrate effects, this intervention has the potential to address aspects of stroke recovery previously. Not routinely addressed in rehabilitation.

The study objectives were to determine the feasibility and effects of providing therapeutic massage at home for patients with metastatic cancer. This was a randomized controlled trial. Patients were enrolled at Oncology Clinics at a large urban academic medical center; massage therapy was provided in patients' homes. Subjects were patients with metastatic cancer. There were three interventions: massage therapy, no-touch intervention, and usual care. Primary outcomes were pain, anxiety, and alertness; secondary outcomes were quality of life and sleep. In this study, it was possible to provide interventions for all patients at home by professional massage therapists. The mean number of massage therapy sessions per patient was 2.8. A significant improvement was found in the quality of life of the patients who received massage therapy after 1-week follow-up, which was not observed in either the No Touch control or the Usual Care control groups, but the difference was not sustained at 1 month. There were trends toward improvement in pain and sleep of the patients after therapeutic massage but not in patients in the control groups. There were no serious adverse events related to the interventions. The study results showed that it is feasible to provide therapeutic massage at home for patients with advanced cancer, and to randomize patients to a no-touch intervention. Providing therapeutic massage improves the quality of life at the end of life for patients and may be associated with further beneficial effects, such as improvement in pain and sleep quality. Larger randomized controlled trials are needed to substantiate these findings.

This randomized controlled trial evaluates the feasibility of using an Embodied Conversational Agent (ECA) to teach lifestyle modifications to urban women. Women were randomized to either 1) an ECA (content included: mindfulness, stress management, physical activity, and healthy eating) or 2) patient education sheets mirroring same content plus a meditation CD/MP3 once a day for one month. General outcome measures included: number of stress management techniques used, physical activity levels, and eating patterns. Sixty-one women ages 18 to 50 were enrolled. On average, 51% identified as white, 26% as black, 23% as other races; and 20% as Hispanic. The major stress management techniques reported at baseline were: exercise (69%), listening to music (70%), and social support (66%). After one month, women randomized to the ECA significantly decreased alcohol consumption to reduce stress (p=0.03) and increased daily fruit consumption by an average of 2 servings compared to the control (p=0.04). It is feasible to use an ECA to promote health behaviors on stress management and healthy eating among diverse urban women. Compared to patient information sheets, ECAs provide promise as a way to teach healthy lifestyle behaviors to diverse urban women. Copyright © 2017 Elsevier B.V. All rights reserved.

Platelet-rich plasma (PRP) has been advocated for treatment of plantar fasciitis but there are few good-quality clinical trials to support its use. We conducted a feasibility study of PRP versus saline for treatment of plantar fasciitis. Patients with 6 months or more of magnetic resonance imaging-proven plantar fasciitis, who had failed conservative treatment were invited to participate in the study. Patients were block randomized to either PRP or an equivalent volume of saline. The techniques used for injection and rehabilitation were standardized for both groups. The patient and assessor were blinded. Visual analogue scale (VAS) for pain and painDETECT score were recorded preoperatively and at 6 months follow-up. From 35 patients approached, 28 (19 female, mean age 50 years) were recruited, with 14 randomized to each arm. At 6 months, 8 patients (28.6%) were lost to follow-up. There was a significant change in VAS score from baseline to follow-up in both intervention (mean change 37.2, P = .008) and control (mean change 42.2, P = .003) groups. There was no correlation between preoperative painDETECT score and change in VAS. Recruitment and loss to follow-up rates were relatively high. Both treatments resulted in a similar, significant, improvement in symptoms. Level II.

This pilot study used a randomized controlled trial design to examine the feasibility and explore initial outcomes of a twice weekly, 8-session Child Directed Interaction Training (CDIT) program for children living in kinship care. Participants included 14 grandmothers and great-grandmothers with their 2- to 7-year-old children randomized either to CDIT or a waitlist control condition. Training was delivered at a local, community library with high fidelity to the training protocol. There was no attrition in either condition. After training, kinship caregivers in the CDIT condition demonstrated more positive relationships with their children during behavioral observation. The caregivers in the CDIT condition also reported clinically and statistically significant decreases in parenting stress and caregiver depression, as well as fewer externalizing child behavior problems than waitlist controls. Parent daily report measures indicated significant changes in disciplining that included greater use of limit-setting and less use of critical verbal force. Results appeared stable at 3-month follow-up. Changes in child internalizing behaviors and caregiver use of non-critical verbal force were not seen until 3-month follow-up. Results of this pilot study suggest both the feasibility of conducting full scale randomized clinical trials of CDIT in the community and the promise of this approach for providing effective parent training for kinship caregivers.

Rationale Individuals with schizophrenia have high smoking-related morbidity and mortality rates and need powerful and innovative smoking cessation interventions. Objectives This proof-of-concept study investigated the feasibility and initial efficacy of combining a contingency management intervention with bupropion to reduce smoking in people with schizophrenia. Methods Using a double-blind, placebo-controlled, between-groups design, 57 non-treatment seeking participants were randomized to receive 300 mg/day bupropion or placebo. One week later, participants were randomized to a contingency management (CM) intervention in which reductions in urinary cotinine levels were reinforced, or a non-contingent reinforcement (NR) condition in which session attendance was reinforced, regardless of cotinine level. Over the 22-day study period, participants visited the laboratory approximately three times per week to provide urine samples for analysis of cotinine levels, to give breath samples for analysis of carbon monoxide (CO) levels, and to report number of cigarettes smoked per day, nicotine withdrawal symptoms, cigarette craving and psychiatric symptoms. Results Cotinine and CO levels significantly decreased during the study period in participants randomized to the CM condition, but not the NR condition. Bupropion did not reduce cotinine levels or increase the efficacy of CM. Cigarette craving and psychiatric symptom levels significantly decreased during the study in all groups. Conclusions The results of this study indicate the efficacy and feasibility of this CM intervention for reducing smoking in individuals with schizophrenia. PMID:21475970

Over the last two decades, lifespan has increased significantly for people living with cystic fibrosis (CF). However, several studies have demonstrated that many young adults with CF report mental health problems and poor adherence to their prescribed treatments, challenging their long-term physical health. Treatment guidelines recommend interventions to improve adherence and self-management. The aim of this study was to test the feasibility of a life coaching intervention for young adults with CF. A randomized, controlled feasibility study was conducted at the CF Center at Copenhagen University Hospital, Rigshospitalet. Participants were young adults with CF, aged 18-30 years without severe intellectual impairments. Participants were randomized to either life coaching or standard care. The intervention consisted of up to 10 individual, face-to-face or telephone coaching sessions over a period of 1 year. Primary outcomes were recruitment success, acceptability, adherence to the intervention, and retention rates. Secondary outcome measures included health-related quality of life, adherence to treatment, self-efficacy, pulmonary function, body mass index, and blood glucose values. Among the 85 eligible patients approached, 40 (47%) were enrolled and randomized to the intervention or control group; two patients subsequently withdrew consent. Retention rates after 5 and 10 coaching sessions were 67% and 50%, respectively. Reasons for stopping the intervention included lack of time, poor health, perceiving coaching as not helpful, lack of motivation, and no need for further coaching. Coaching was primarily face-to-face (68%). No significant differences were found between the groups on any of the secondary outcomes. Both telephone and face-to-face coaching were convenient for participants, with 50% receiving the maximum offered coaching sessions. However, the dropout rate early in the intervention was a concern. In future studies, eligible participants should be screened for their interest and perceived need for support and life coaching before enrollment.

Depression is common among dialysis patients and is associated with adverse outcomes. Problem-solving therapy (PST) is effective for treating depression in older patients with chronic illness, but its effectiveness has never been reported in hemodialysis (HD) patients. We investigated the feasibility and satisfaction of PST and its impact on depression scores among older HD patients. Patients at least 60 years of age receiving maintenance HD at a single outpatient dialysis center were eligible for the study. Randomized patients received either 6 weeks of PST from a licensed renal social worker or usual care. This study modeled the staff-patient ratio standard of most dialysis clinics, and therefore only one social worker provided the interventions. Study outcomes included feasibility (successful completion of 6 weekly sessions) and patient satisfaction with PST as well as impact on depression scores (between-group comparison of mean Beck depression inventory (BDI) and Patient health questionnaire-9 (PHQ-9) scores at 6 weeks, and of mean change-from-baseline scores). The recruitment rate was 92% (35/38). All subjects randomized to the intervention arm (n = 17) and who initiated PST (n = 15) completed the study, and all reported overall satisfaction with the intervention. 87% reported that PST helped them to better solve problems and improved their ability to cope with their medical condition. At 6 weeks, there were no significant differences in mean BDI and PHQ scores between the usual care and the intervention group (BDI 11.3 vs. 9.3, p = 0.6; PHQ 5.7 vs. 3.3, p = 0.1). Mean change-from-baseline depression scores were significantly improved in the intervention group relative to the control group (change in BDI 6.3 vs.- 0.6, p = 0.004; change in PHQ 7.2 vs. 0.3, p < 0.001). The results demonstrate that PST is feasible in the dialysis unit setting, acceptable to patients, and may positively impact depression among maintenance hemodialysis patients.

The importance of leadership to influence nurses' use of clinical guidelines has been well documented. However, little is known about how to develop and evaluate leadership interventions for guideline use. The purpose of this study was to pilot a leadership intervention designed to influence nurses' use of guideline recommendations when caring for patients with diabetic foot ulcers in home care nursing. This paper reports on the feasibility of implementing the study protocol, the trial findings related to nursing process outcomes, and leadership behaviors. A mixed methods pilot study was conducted with a post-only cluster randomized controlled trial and descriptive qualitative interviews. Four units were randomized to control or experimental groups. Clinical and management leadership teams participated in a 12-week leadership intervention (workshop, teleconferences). Participants received summarized chart audit data, identified goals for change, and created a team leadership action. Criteria to assess feasibility of the protocol included: design, intervention, measures, and data collection procedures. For the trial, chart audits compared differences in nursing process outcomes. 8-item nursing assessments score. Secondary outcome: 5-item score of nursing care based on goals for change identified by intervention participants. Qualitative interviews described leadership behaviors that influenced guideline use. Conducting this pilot showed some aspects of the study protocol were feasible, while others require further development. Trial findings observed no significant difference in the primary outcome. A significant increase was observed in the 5-item score chosen by intervention participants (p = 0.02). In the experimental group more relations-oriented leadership behaviors, audit and feedback and reminders were described as leadership strategies. Findings suggest that a leadership intervention has the potential to influence nurses' use of guideline recommendations, but further work is required to refine the intervention and outcome measures. A taxonomy of leadership behaviors is proposed to inform future research. © 2012 The authors. World Views on Evidence-Based Nursing © Sigma Theta Tau International.

Interest in improving care for the growing number of individuals with chronic conditions is rising. However, access to care is limited by distance, disability, and distribution of doctors. Small-scale studies in Parkinson disease, a prototypical chronic condition, have suggested that delivering care using video house calls is feasible, offers similar clinical outcomes to in-person care, and reduces travel burden. We are conducting a randomized comparative effectiveness study (Connect.Parkinson) comparing usual care in the community to usual care augmented by virtual house calls with a Parkinson disease specialist. Recruitment is completed centrally using online advertisements and emails and by contacting physicians, support groups, and allied health professionals. Efforts target areas with a high proportion of individuals not receiving care from neurologists. Approximately 200 individuals with Parkinson disease and their care partners will be enrolled at 20 centers throughout the United States and followed for one year. Participants receive educational materials, then are randomized in a 1:1 ratio to continue their usual care (control arm) or usual care and specialty care delivered virtually (intervention arm). Care partners are surveyed about their time and travel burden and their perceived caregiver burden. Participants are evaluated via electronic survey forms and videoconferencing with a blinded independent rater at baseline and at 12 months. All study activities are completed remotely.The primary outcomes are: (1) feasibility, as measured by the proportion of visits completed, and (2) quality of life, as measured by the 39-item Parkinson's Disease Questionnaire. Secondary outcomes include measures of clinical benefit, quality of care, time and travel burden, and caregiver burden. Connect.Parkinson will evaluate the feasibility and effectiveness of using technology to deliver care into the homes of individuals with Parkinson disease. The trial may serve as a model for increasing access and delivering patient-centered care at home for individuals with chronic conditions. This trial was registered on clinicaltrials.gov on January 8, 2014 [NCT02038959].

To assess efficacy of 2 worksite health promotion interventions. Randomly assign 3 fire stations to (a) team-based curriculum, (b) individual counselor meetings, and (c) control. Both interventions were feasible and acceptable, and they resulted in significant reductions in LDL cholesterol. The team approach significantly increased coworker cohesion, personal exercise habits, and coworkers' healthy behaviors. The one-on-one strategy significantly increased dietary self-monitoring, decreased fat intake, and reduced depressed feelings. Although both interventions promoted healthy behaviors, specific outcomes differed and reflected their conceptual underpinnings. The team-based curriculum is innovative and may enlist influences not accessed with individual formats.

Background Exercise training may have the potential to improve post-thrombotic syndrome, a frequent, chronic complication of deep venous thrombosis. We conducted a randomized controlled two-centre pilot trial to assess the feasibility of a multicentre-based evaluation of a six-month exercise training program to treat post-thrombotic syndrome and to obtain preliminary data on the effectiveness of such a program. Methods Patients were randomized to receive exercise training (a six-month trainer-supervised program) or control treatment (an education session with monthly phone follow-ups). Levels of eligibility, consent, adherence and retention were used as indicators of study feasibility. Primary outcomes were change from baseline to six months in venous disease-specific quality of life (as measured using the Venous Insufficiency Epidemiological and Economic Study Quality of Life [VEINES-QOL] questionnaire) and severity of post-thrombotic syndrome (as measured by scores on the Villalta scale) in the exercise training group versus the control group, assessed by t tests. Secondary outcomes were change in generic quality of life (as measured using the Short-Form Health Survey-36 [SF-36] questionnaire), category of severity of post-thrombotic syndrome, leg strength, leg flexibility and time on treadmill. Results Of 95 patients with post-thrombotic syndrome, 69 were eligible, 43 consented and were randomized, and 39 completed the study. Exercise training was associated with improvement in VEINES-QOL scores (exercise training mean change 6.0, standard deviation [SD] 5.1 v. control mean change 1.4, SD 7.2; difference 4.6, 95% CI 0.54 to 8.7; p = 0.027) and improvement in scores on the Villalta scale (exercise training mean change −3.6, SD 3.7 v. control mean change −1.6, SD 4.3; difference −2.0, 95% CI −4.6 to 0.6; p = 0.14). Most secondary outcomes also showed greater improvement in the exercise training group. Interpretation Exercise training may improve post-thrombotic syndrome. It would be feasible to definitively evaluate exercise training as a treatment for post-thrombotic syndrome in a large multicentre trial. PMID:21098066

Reducing aspiration of gastric contents by placing mechanically ventilated patients in a semirecumbent position has been associated with lower incidences of ventilator-associated pneumonia (VAP). The feasibility and efficacy of this intervention in a larger patient population, however, are unknown. Assessment of the feasibility of the semirecumbent position for intensive care unit patients and its influence on development of VAP. In a prospective multicentered trial, critically ill patients undergoing mechanical ventilation were randomly assigned to the semirecumbent position, with a target backrest elevation of 45 degrees , or standard care (i.e., supine position) with a backrest elevation of 10 degrees . Backrest elevation was measured continuously during the first week of ventilation with a monitor-linked device. A deviation of position was defined as a change of the randomized position >5 degrees . Diagnosis of VAP was made by quantitative cultures of samples obtained by bronchoscopic techniques. One hundred nine patients were assigned to the supine group and 112 to the semirecumbent group. Baseline characteristics were comparable for both groups. Average elevations were 9.8 degrees and 16.1 degrees at day 1 and day 7, respectively, for the supine group and 28.1 degrees and 22.6 degrees at day 1 and day 7, respectively, for the semirecumbent group (p < .001). The target semirecumbent position of 45 degrees was not achieved for 85% of the study time, and these patients more frequently changed position than supine-positioned patients. VAP was diagnosed in eight patients (6.5%) in the supine group and in 13 (10.7%) in the semirecumbent group (NS), after a mean of 6 (range, 3-9) and 7 (range, 3-12) days, respectively. There were no differences in numbers of patients undergoing enteral feeding, receiving stress ulcer prophylaxis, or developing pressure sores or in mortality rates or duration of ventilation and intensive care unit stay between the groups. The targeted backrest elevation of 45 degrees for semirecumbent positioning was not reached in the conditions of the present randomized study. The achieved difference in treatment position (28 degrees vs. 10 degrees ) did not prevent the development of VAP.

To examine the feasibility of a clinical trial on a novel, home-based task-oriented training with conventional hand exercises in people with rheumatoid arthritis or hand osteoarthritis. To explore the experiences of participants who completed their respective home exercise programmes. Thirty volunteer participants aged between 30 and 60 years and diagnosed with rheumatoid arthritis or hand osteoarthritis were proposed for a single-center, assessor-blinded, randomized controlled trial ( ClinicalTrials.gov : NCT01635582). Participants received task-oriented training with interactive computer games and objects of daily life or finger mobility and strengthening exercises. Both programmes were home based and were done four sessions per week with 20 minutes each session for 6 weeks. Major feasibility outcomes were number of volunteers screened, randomized, and retained; completion of blinded assessments, exercise training, and home exercise sessions; equipment and data management; and clinical outcomes of hand function. Reaching the recruitment target in 18 months and achieving exercise compliance >80% were set as success criteria. Concurrent with the trial, focus group interviews explored experiences of those participants who completed their respective programmes. After trial initiation, revisions in inclusion criteria were required to promote recruitment. A total of 17 participants were randomized and 15 were retained. Completion of assessments, exercise training, and home exercise sessions; equipment and data collection and management demonstrated excellent feasibility. Both groups improved in hand function outcomes and exercise compliance was above 85%. Participants perceived both programmes as appropriate and acceptable. Participants who completed task-oriented training also agreed that playing different computer games was enjoyable, engaging, and motivating. Findings demonstrate initial evidence on recruitment, feasibility of trial procedures, and acceptability of task-oriented training in people with rheumatoid arthritis or hand osteoarthritis. Since the pilot trial was unsuccessful in participant recruitment, a large trial will not follow.

Background The comorbidity of type 2 diabetes mellitus (T2DM) and depression is associated with poor glycemic control. Exercise has been shown to improve mood and glycemic control, but individuals with comorbid T2DM and depression are disproportionately sedentary compared to the general population and report more difficulty with exercise. Behavioral activation, an evidence-based depression psychotherapy, was designed to help people with depression make gradual behavior changes, and may be helpful to build exercise adherence in sedentary populations. This pilot randomized clinical trial will test the feasibility of a group exercise program enhanced with behavioral activation strategies among women with comorbid T2DM and depression. Methods/Design Sedentary women with inadequately controlled T2DM and depression (N=60) will be randomly assigned to one of two conditions: exercise or usual care. Participants randomized to the exercise condition will attend 38 behavioral activation-enhanced group exercise classes over 24 weeks in addition to usual care. Participants randomized to the usual care condition will receive depression treatment referrals and print information on diabetes management via diet and physical activity. Assessments will occur at baseline and 3-, 6-, and 9-months following randomization. The goals of this pilot study are to demonstrate feasibility and intervention acceptability, estimate the resources and costs required to deliver the intervention and to estimate the standard deviation of continuous outcomes (e.g., depressive symptoms and glycosylated hemoglobin) in preparation for a fully-powered randomized clinical trial. Discussion A novel intervention that combines exercise and behavioral activation strategies could potentially improve glycemic control and mood in women with comorbid type 2 diabetes and depression.

There is robust clinical evidence to support offering early access to antiretroviral treatment (ART) to all HIV-positive individuals, irrespective of disease stage, to both improve patient health outcomes and reduce HIV incidence. However, as the global treatment guidelines shift to meet this evidence, it is still largely unknown if early access to ART for all (also referred to as "treatment as prevention" or "universal test and treat") is a feasible intervention in the resource-limited countries where this approach could have the biggest impact on the course of the HIV epidemics. The MaxART Early Access to ART for All (EAAA) implementation study was designed to determine the feasibility, acceptability, clinical outcomes, affordability, and scalability of offering early antiretroviral treatment to all HIV-positive individuals in Swaziland's public sector health system. This is a three-year stepped-wedge randomized design with open enrollment for all adults aged 18 years and older across 14 government-managed health facilities in Swaziland's Hhohho Region. Primary endpoints are retention and viral suppression. Secondary endpoints include ART initiation, adherence, drug resistance, tuberculosis, HIV disease progression, patient satisfaction, and cost per patient per year. Sites are grouped to transition two at a time from the control (standard of care) to intervention (EAAA) stage at each four-month step. This design will result in approximately one half of the total observation time to accrue in the intervention arm and the other half in the control arm. Our estimated enrolment number, which is supported by conservative power calculations, is 4501 patients over the course of the 36-month study period. A multidisciplinary, mixed-methods approach will be adopted to supplement the randomized controlled trial and meet the study aims. Additional study components include implementation science, social science, economic evaluation, and predictive HIV incidence modeling. A stepped-wedge randomized design is a causally strong and robust approach to determine if providing antiretroviral treatment for all HIV-positive individuals is a feasible intervention in a resource-limited, public sector health system. We expect our study results to contribute to health policy decisions related to the HIV response in Swaziland and other countries in sub-Saharan Africa. ClinicalTrials.gov, NCT02909218 .

To investigate the feasibility and effects of a physical exercise programme on functioning and health-related quality of life in adults with myotonic dystrophy type 1. A randomized controlled trial. Thirty-five adults with myotonic dystrophy type 1. After stratification for level of functioning, study participants were assigned by lot to either a training group or a control group. Training-group participants attended a 60-minute comprehensive group-training programme, Friskis&Svettis® Open Doors, twice a week for 14 weeks. The six-minute walk test was the primary outcome measure and the timed-stands test, the timed up-and-go test, the Epworth sleepiness scale and the Short Form-36 health survey were secondary outcome measures. Intention-to-treat analyses revealed no significant differences in any outcome measures, except for an increased between-group difference after intervention in the Short Form-36 mental health subscale and a decrease in the vitality subscale for the control group. The programme was well tolerated and many training-group participants perceived subjective changes for the better. No negative effects were reported. The Friskis&Svettis® Open Doors programme was feasible for adults with myotonic dystrophy type 1 who had been screened for cardiac involvement, had distal or mild-to-moderate proximal muscle impairment, and no severe cognitive impairments. No beneficial or detrimental effects were evident.

To evaluate the feasibility of a grocery store tour for parents and their adolescents being led by adults or adolescent peers. Randomized controlled pilot study with surveys at baseline and post-program, and at 3- and 6-month follow-up. Midwestern midsized grocery stores. Sixty-one parents and their 71 11- to 14-year-old adolescents. Nutrition education during 1 90-minute grocery store tour. Process observations and participants' tour perceptions provided fidelity outcomes. Questionnaires quantitatively assessed participants' knowledge, self-efficacy, and tour strategy use. Chi-square and McNemar tests were used to analyze categorical data, and Kruskal-Wallis, Wilcoxon signed-rank, and Mann-Whitney U tests were employed for continuous variables (significance at P < .05). Over 90% of tour tasks were rated as completed well for adult and peer leaders. Participants had positive tour perceptions but noted deficiencies in teen leaders' knowledge and leadership skills. Overall, parents and adolescents retained increased self-efficacy from pre-tour to post-tour intervals. Despite limited knowledge retention, parents reported they had increased (6.5 ± 4.19) healthful grocery shopping behaviors in the 6 months after the intervention. Peers may feasibly lead grocery store tours but they may need additional resources and support to be highly effective. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

We conducted a pilot randomized controlled trial to determine the feasibility and acceptability of a patient navigation intervention. Forty-seven smokers from one safety-net hospital were randomized to either a control group, in which they received a smoking cessation brochure and a list of smoking cessation resources, or a navigation group, in which they received the smoking cessation brochure, a list of smoking cessation resources, and patient navigation. Follow-up data were obtained for 33 participants. Nine (47.4%) of 19 of navigation group participants had engaged in smoking cessation treatment by 3 months versus 6 (42.9%) of 14 control group participants (chi-square p = ns). Patient navigation to promote engagement in smoking cessation treatment was feasible and acceptable to participants.

This parallel-group, randomized controlled pilot study examined daily meditation in a diverse sample of older adults with postherpetic neuralgia. Block randomization was used to allocate participants to a treatment group (n = 13) or control group (n = 14). In addition to usual care, the treatment group practiced daily meditation for six weeks. All participants completed questionnaires at enrollment in the study, two weeks later, and six weeks after that, at the study's end. Participants recorded daily pain and fatigue levels in a diary, and treatment participants also noted meditation practice. Results at the 0.10 level indicated improvement in neuropathic, affective, and total pain scores for the treatment group, whereas affective pain worsened for the control group. Participants were able to adhere to the daily diary and meditation requirements in this feasibility pilot study. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this study was to demonstrate feasibility and safety of a new electric duodenal stimulation system (EDS, BALANCE) in humans. Secondary objectives were to evaluate the effect on glycemic control and weight loss in patients with obesity and type 2 diabetes mellitus (T2DM). In an open-labeled, prospective, single-arm, non-randomized multicenter study, 12 obese T2DM patients with a mean HbA1c of 8.0% received laparoscopic implantation of the BALANCE duodenal stimulating device. Adverse events, changes in glycemic control, cardiovascular parameters, and weight were collected. The follow-up period after implantation was 12 months. Device related severe adverse events did not occur. Mean HbA1c decreased by 0.8% (p = 0.02) and mean fasting blood glucose level (FBG) was reduced by 19% (p = 0.038) after the 12 months. Mean HDL level increased from 44 to 48 mg/dl (p = 0.033). EDS is a feasible and safe procedure. Positive effects on T2DM and some cardiovascular parameters (HDL, weight) were seen. However, further prospective randomized blinded studies are needed in order to evaluate the potential of this new minimally invasive method.

There is a need for robust, fully automated whole body organ segmentation for diagnostic CT. This study investigates and optimizes a Random Forest algorithm for automated organ segmentation; explores the limitations of a Random Forest algorithm applied to the CT environment; and demonstrates segmentation accuracy in a feasibility study of pediatric and adult patients. To the best of our knowledge, this is the first study to investigate a trainable Weka segmentation (TWS) implementation using Random Forest machine-learning as a means to develop a fully automated tissue segmentation tool developed specifically for pediatric and adult examinations in a diagnostic CT environment. Current innovation in computed tomography (CT) is focused on radiomics, patient-specific radiation dose calculation, and image quality improvement using iterative reconstruction, all of which require specific knowledge of tissue and organ systems within a CT image. The purpose of this study was to develop a fully automated Random Forest classifier algorithm for segmentation of neck-chest-abdomen-pelvis CT examinations based on pediatric and adult CT protocols. Seven materials were classified: background, lung/internal air or gas, fat, muscle, solid organ parenchyma, blood/contrast enhanced fluid, and bone tissue using Matlab and the TWS plugin of FIJI. The following classifier feature filters of TWS were investigated: minimum, maximum, mean, and variance evaluated over a voxel radius of 2 n , (n from 0 to 4), along with noise reduction and edge preserving filters: Gaussian, bilateral, Kuwahara, and anisotropic diffusion. The Random Forest algorithm used 200 trees with 2 features randomly selected per node. The optimized auto-segmentation algorithm resulted in 16 image features including features derived from maximum, mean, variance Gaussian and Kuwahara filters. Dice similarity coefficient (DSC) calculations between manually segmented and Random Forest algorithm segmented images from 21 patient image sections, were analyzed. The automated algorithm produced segmentation of seven material classes with a median DSC of 0.86 ± 0.03 for pediatric patient protocols, and 0.85 ± 0.04 for adult patient protocols. Additionally, 100 randomly selected patient examinations were segmented and analyzed, and a mean sensitivity of 0.91 (range: 0.82-0.98), specificity of 0.89 (range: 0.70-0.98), and accuracy of 0.90 (range: 0.76-0.98) were demonstrated. In this study, we demonstrate that this fully automated segmentation tool was able to produce fast and accurate segmentation of the neck and trunk of the body over a wide range of patient habitus and scan parameters.

This randomized pilot trial evaluated two training modalities for first-line, evidence-based pediatric obesity services (screening and goal setting) among nursing students. Participants (N = 63) were randomized to live interactive training or Web-facilitated self-study training. Pretraining, post-training, and 1-month follow-up assessments evaluated training feasibility, acceptability, and impact (knowledge and skill via simulation). Moderator (previous experience) and predictor (content engagement) analyses were conducted. Nearly all participants (98%) completed assessments. Both types of training were acceptable, with higher ratings for live training and participants with previous experience (ps < .05). Knowledge and skill improved from pretraining to post-training and follow-up in both conditions (ps < .001). Live training demonstrated greater content engagement (p < .01). The training package was feasible, acceptable, and efficacious among nursing students. Given that live training had higher acceptability and engagement and online training offers greater scalability, integrating interactive live training components within Web-based training may optimize outcomes, which may enhance practitioners' delivery of pediatric obesity services.

We conducted a pilot randomized controlled trial (RCT) comparing a prenatal yoga intervention to perinatal-focused health education in pregnant women with depression. Findings document acceptability and feasibility of the yoga intervention: no yoga-related injuries were observed, instructors showed fidelity to the yoga manual, and women rated interventions as acceptable. Although improvements in depression were not statistically different between groups, they favored yoga. This study provides support for a larger scale RCT examining prenatal yoga to improve mood during pregnancy.
A randomized evaluation of smoking cessation interventions for pregnant women at a WIC clinic.
Mayer, J P; Hawkins, B; Todd, R
1990-01-01
Pregnant smokers attending a local health department WIC clinic were randomly assigned to one of two self-help smoking cessation programs or usual care. The multiple component program resulted in larger quit rates than usual care during the last month of pregnancy (11 percent vs 3 percent) and postpartum (7 percent vs 0 percent). Achieving quit rates in WIC similar to those in studies conducted at prenatal care settings, suggests that smoking cessation programs for low-income pregnant WIC clients are feasible. PMID:2293809

Background Although it is known both patients’ and partners’ reactions to a prostate cancer diagnosis include fear, uncertainty, anxiety and depression with patients’ partners’ reactions mutually determining how they cope with and adjust to the illness, few psychosocial interventions target couples. Those that are available tend to be led by highly trained professionals, limiting their accessibility and long-term sustainability. In addition, it is recognised that patients who might benefit from conventional face-to-face psychosocial interventions do not access these, either by preference or because of geographical or mobility barriers. Self-directed interventions can overcome some of these limitations and have been shown to contribute to patient well-being. This study will examine the feasibility of a self-directed, coping skills intervention for couples affected by cancer, called Coping-Together, and begin to explore its potential impact on couples’ illness adjustment. The pilot version of Coping-Together includes a series of four booklets, a DVD, and a relaxation audio CD. Methods/design In this double-blind, two-group, parallel, randomized controlled trial, 70 couples will be recruited within 4 months of a prostate cancer diagnosis through urology private practices and randomized to: 1) Coping-Together or 2) a minimal ethical care condition. Minimal ethical care condition couples will be mailed information booklets available at the Cancer Council New South Wales and a brochure for the Cancer Council Helpline. The primary outcome (anxiety) and additional secondary outcomes (distress, depression, dyadic adjustment, quality of life, illness or caregiving appraisal, self-efficacy, and dyadic and individual coping) will be assessed at baseline (before receiving study material) and 2 months post-baseline. Intention-to-treat and per protocol analysis will be conducted. Discussion As partners’ distress rates exceed not only population norms, but also those reported by patients themselves, it is imperative that coping skills interventions target the couple as a unit and enhance both partners’ ability to overcome cancer challenges. This pilot study will examine the feasibility and potential efficacy of Coping-Together in optimising couples’ illness adjustment. This is one of the first feasibility studies to test this innovative coping intervention, which in turn will contribute to the larger literature advocating for psychosocial care of couples affected by prostate cancer.

To assess the acceptability and feasibility of S2S, a newly adapted behavior intervention to address high-risk sexual behavior. Pilot randomized controlled trial. The Internet and text messages with no in-person interactions. Eighty-eight Black women, ages 18 to 24 years, were randomly assigned to the intervention or control groups and self-enrolled in the respective text message program. Participants in the intervention group were sent text messages about sexual health, whereas those in the control group were sent text messages about diet and/or exercise. Participants in each group received 24 text messages, including text-only messages, memes, and infopics. Participants in the intervention group also received videos links. All text messages were sent three times per week for 8 weeks. Quantitative methods were used to analyze data from the message and video platform reports. Quantitative and qualitative methods were used to analyze participants' responses to an acceptability and feasibility survey. Overall, the delivery of health promotion text messages was viewed as acceptable and feasible by participants in both groups. Most of the short answer responses from participants were favorable, and responses to the acceptability and feasibility survey yielded a total mean score of 4.01 on a 5-point scale. Results from this study support the idea that evidence-based interventions can be adapted for delivery by text message. This delivery modality is acceptable to young adult Black women and may help decrease barriers that would otherwise prevent them from receiving health promotion messages.

Patients with head and neck cancer (HNC) experience involuntary weight loss that has a negative impact on physical function, morbidity, and survival. The objective of the current study was to evaluate the feasibility of an exercise and nutrition intervention during radiotherapy (RT) compared with after RT, and to examine preliminary effects on skeletal muscle mass. Patients with HNC were randomized to an exercise and nutrition intervention during RT (EN-DUR) or after RT (EN-AF). The EN-DUR intervention was conducted at a hospital and the EN-AF intervention took place at a rehabilitation center. The interventions consisted of progressive resistance training (PRT) and oral nutritional supplements (ONS). Feasibility outcomes were tracked weekly and muscle mass was measured by computed tomography scans before and after RT and at 2 months follow-up. Of the 50 eligible patients, 41 (82%) agreed to participate. 90% of patients completed the EN-DUR intervention and the adherence to PRT and ONS was 81% and 57%, respectively. 52% of patients attended the EN-AF intervention and adherence to PRT and ONS was 94% and 76%, respectively. The EN-DUR demonstrated a trend toward mitigating loss of muscle mass during RT and the EN-AF demonstrated a similar trend after RT. No difference in muscle mass was detected between the groups from baseline to week 14. An exercise and nutrition intervention is feasible for patients with HNC during RT, and the intervention is potentially effective in mitigating loss of muscle mass both during and after RT. Future trials should assess the feasibility and effects of extended interventions during and after treatment. Cancer 2017;123:4440-8. © 2017 American Cancer Society. © 2017 American Cancer Society.

Increasing colorectal cancer screening (CRCS) can have a substantial positive impact on morbidity and mortality. The purpose of this report is to describe the development and feasibility testing of a computer-based, theory-guided educational program designed to increase CRCS. This mixed-methods study used focus groups and subsequent randomized controlled trial design. Participants (N = 199) were randomized to an intervention or control group; 75% were African American; mean age was 57.36 (SD = 6.8); 71% were male. Previously validated measures on knowledge, beliefs, and screening test adherence were used to establish pre- and post-intervention perceptions. Feasibility was measured by response and completion rates, and participants' perceptions of the program. Before feasibility testing, the program was presented to 2 focus groups. Changes were made to the program based on discussion, leading to a visually appealing, easy to understand and navigate, self-paced program. In the RCT pilot test that followed, of the participants in the intervention group, 80% said the education helped them decide to get CRCS; 49% agreed it helped them overcome barriers; 91% agreed it was useful, 68% thought it raised new concerns about cancer, but only 30% said it made them worry about CRC; 95% agreed their doctor's office should continue giving such education, and 99% said they would inform family about the program. The response rate of 83% demonstrated feasibility of conducting colorectal cancer education in the primary care setting; overall the program was well received; participants averaged 23 minutes to complete it. Participants sought no help from attending data collectors and navigated the revised touch screen program with ease. Computer-based education is feasible in primary care clinics.

To evaluate the feasibility of implementing an interdisciplinary, multifaceted knowledge translation intervention within long-term care (LTC) and to identify any challenges that should be considered in designing future studies. Cluster randomized controlled trial. Forty LTC homes across the province of Ontario, Canada. LTC teams composed of physicians, nurses, pharmacists, and other staff. Cluster-level feasibility measures, including recruitment, retention, data completion, and participation in the intervention. A process evaluation was completed by directors of care indicating which process/policy changes had been implemented. Recruitment and retention rates were 22% and 63%, respectively. Good fidelity with the intervention was achieved, including attendance at educational meetings. After ViDOS, 7 process indicators were being newly implemented by more than 50% of active intervention homes. Despite recruitment and retention challenges, the multifaceted intervention produced a number of policy/process changes and had good intervention fidelity.

This study examined the feasibility, acceptability, and potential efficacy of a gross motor skill program for toddlers. An 8-wk. skills program in which children practiced three skills was implemented for 10 min. daily in two randomly designated childcare centers. Two other centers served as the control group. Recruitment and retention rates were collected for feasibility. Data on professional development, children's participation, program duration, and appropriateness of the lessons were collected for acceptability, and the Test of Gross Motor Development-2 and Get Skilled, Get Active (total of 28 points) were used to look at the potential efficacy. The participants were 60 toddlers (M age=2.5 yr., SD=0.4; n=29 boys), and the retention rate was 95%. Overall participation was 76%, and educators rated 98% of the lessons as appropriate. Compared with the control group, the intervention group showed significantly greater improvements in motor skills (p<.05, Cohen's d=1.13). This study shows that a brief intervention, which is easy to integrate on a daily basis in childcare settings, can improve motor skills among toddlers.
The Feasibility and Acceptability of LISTEN for Loneliness

2015-01-01
Purpose The purpose of this paper is to present the initial feasibility and acceptability of LISTEN (Loneliness Intervention using Story Theory to Enhance Nursing-sensitive outcomes), a new intervention for loneliness. Loneliness is a significant stressor and known contributor to multiple chronic health conditions in varied populations. In addition, loneliness is reported as predictive of functional decline and mortality in large samples of older adults from multiple cultures. Currently, there are no standard therapies recommended as effective treatments for loneliness. The paucity of interventions has limited the ability of healthcare providers to translate what we know about the problem of loneliness to active planning of clinical care that results in diminished loneliness. LISTEN was developed using the process for complex intervention development suggested by the Medical Research Council (MRC) [1] [2]. Methods Feasibility and acceptability of LISTEN were evaluated as the first objective of a longitudinal randomized trial which was set in a university based family medicine center in a rural southeastern community in Appalachia. Twenty-seven older adults [(24 women and 3 men, mean age: 75 (SD 7.50)] who were lonely, community-dwelling, and experiencing chronic illness, participated. Feasibility was evaluated by tracking recruitment efforts, enrollment, attendance to intervention sessions, attrition, and with feedback evaluations from study personnel. Acceptability was assessed using quantitative and qualitative evaluation data from participants. Results LISTEN was evaluated as feasible to deliver with no attrition and near perfect attendance. Participants ranked LISTEN as highly acceptable for diminishing loneliness with participants requesting a continuation of the program or development of additional sessions. Conclusions LISTEN is feasible to deliver in a primary healthcare setting and has the potential to diminish loneliness which could result in improvement of the long-term negative known sequelae of loneliness such as hypertension, depression, functional decline, and mortality. Feedback from study participants is being used to inform future trials of LISTEN with consideration for developing additional sessions. Longitudinal randomized trials are needed in varied populations to assess long-term health and healthcare system benefits of diminishing loneliness, and to assess the potential scalability of LISTEN as a reimbursable treatment for loneliness.

Self-care practices in heart failure (HF) contribute to quality of life, symptom stabilization, and extended life expectancy. However, adherence to practices such as liquid and salt restriction or symptom monitoring require high motivation on a daily basis. The aim was to assess the feasibility, acceptability, and potential effectiveness of a nursing intervention with family caregivers, aimed at improving self-care practice of HF patients. This pilot study involved 32 HF patient-caregiver dyads (16/group) randomized to an experimental (EG) or control group (CG). The intervention, based on the Self-Determination Theory, was designed to enhance patients' autonomy and motivation in self-care practices, by involving their caregivers' support. Five encounters were planned with the EG dyads-two face-to-face during hospitalization and three by telephone after discharge. The feasibility of delivering the protocol was evaluated as well as the acceptability of the intervention. The potential effectiveness of the intervention was assessed based on patient outcomes, including general self-care management and self-care specific to HF, perceived competence to manage HF, autonomous motivation (A-motivation, external extrinsic motivation, internal extrinsic motivation, and intrinsic motivation), and perceived support from the caregiver. Caregiver outcomes included level of support provided to the patient. Despite recruitment challenges, the intervention was feasible, with 12 of the 16 dyads receiving all 5 encounters delivered per protocol. The 4 other dyads received the two hospital encounters, but at least 1 of the 3 post-discharge planned telephone encounters was not feasible because the patients had been re-hospitalized or was deceased. Participant's satisfaction with the intervention was high. Outcomes favoring the EG include self-care specific to HF, internal extrinsic motivation, intrinsic motivation, and caregiver's feeling that they provide a higher level of support. Caregiver involvement was found to be both a feasible and acceptable means of supporting self-care practice in HF patients. This approach presents a potential avenue for enhancing patients' efforts in this regard. However, this pilot study offers preliminary findings only, which need to be replicated in a phase 3 clinical trial.

Introduction This study assessed the feasibility and efficacy of a novel resistance training device used within an intradialytic progressive resistance training (PRT) intervention. Methods Non-randomized, within-subjects crossover design with outcomes assessed at baseline (week 0), postcontrol (week 13) and post-PRT intervention (week 26). Twenty-two hemodialysis patients (59% men, 71 ± 11 years) performed PRT three sessions per week for 12 weeks. The resistance training device was developed to enable the performance of 2 upper body and 3 lower body exercises, unilaterally and bilaterally, both before and during dialysis, with loads of 2.5 to 59 kg. Feasibility outcomes included adverse events, adherence and training load progression. Changes in upper and lower body muscular strength, six-minute walk, aspects of health-related quality of life (HRQoL) and depression were evaluated. Findings The PRT intervention was delivered without serious adverse events, resulted in 71.2% ± 23.3% adherence and significant adaptation of all training loads from pre to mid to post training (83.8%-185.6%, all P < 0.05). Lower body strength (P < 0.001) and HRQoL subscales (Role-Physical, Social Functioning, Role-Emotional) significantly increased (all P < 0.01) and a trend toward reduced depression was noted (P = 0.06). No significant changes were noted in other outcomes. Discussion PRT using the novel resistance training device was feasible and improved measures of physical and psychological health. This device can be utilized in most dialysis centers. Future studies are required to evaluate dose-response effects of PRT prescriptions in subpopulations, and the translation of PRT to standard dialysis practice. © 2016 International Society for Hemodialysis.

Objective: To determine whether providing remote neurologic care into the homes of people with Parkinson disease (PD) is feasible, beneficial, and valuable. Methods: In a 1-year randomized controlled trial, we compared usual care to usual care supplemented by 4 virtual visits via video conferencing from a remote specialist into patients' homes. Primary outcome measures were feasibility, as measured by the proportion who completed at least one virtual visit and the proportion of virtual visits completed on time; and efficacy, as measured by the change in the Parkinson's Disease Questionnaire–39, a quality of life scale. Secondary outcomes included quality of care, caregiver burden, and time and travel savings. Results: A total of 927 individuals indicated interest, 210 were enrolled, and 195 were randomized. Participants had recently seen a specialist (73%) and were largely college-educated (73%) and white (96%). Ninety-five (98% of the intervention group) completed at least one virtual visit, and 91% of 388 virtual visits were completed. Quality of life did not improve in those receiving virtual house calls (0.3 points worse on a 100-point scale; 95% confidence interval [CI] −2.0 to 2.7 points; p = 0.78) nor did quality of care or caregiver burden. Each virtual house call saved patients a median of 88 minutes (95% CI 70–120; p < 0.0001) and 38 miles per visit (95% CI 36–56; p < 0.0001). Conclusions: Providing remote neurologic care directly into the homes of people with PD was feasible and was neither more nor less efficacious than usual in-person care. Virtual house calls generated great interest and provided substantial convenience. ClinicalTrials.gov identifier: NCT02038959. Classification of evidence: This study provides Class III evidence that for patients with PD, virtual house calls from a neurologist are feasible and do not significantly change quality of life compared to in-person visits. The study is rated Class III because it was not possible to mask patients to visit type. PMID:28814455

The aim of this study is to outline a general process for assessing the feasibility of performing a valid network meta-analysis (NMA) of randomized controlled trials (RCTs) to synthesize direct and indirect evidence for alternative treatments for a specific disease population. Several steps to assess the feasibility of an NMA are proposed based on existing recommendations. Next, a case study is used to illustrate this NMA feasibility assessment process in order to compare everolimus in combination with hormonal therapy to alternative chemotherapies in terms of progression-free survival for women with advanced breast cancer. A general process for assessing the feasibility of an NMA is outlined that incorporates explicit steps to visualize the heterogeneity in terms of treatment and outcome characteristics (Part A) as well as the study and patient characteristics (Part B). Additionally, steps are performed to illustrate differences within and across different types of direct comparisons in terms of baseline risk (Part C) and observed treatment effects (Part D) since there is a risk that the treatment effect modifiers identified may not explain the observed heterogeneity or inconsistency in the results due to unexpected, unreported or unmeasured differences. Depending on the data available, alternative approaches are suggested: list assumptions, perform a meta-regression analysis, subgroup analysis, sensitivity analyses, or summarize why an NMA is not feasible. The process outlined to assess the feasibility of an NMA provides a stepwise framework that will help to ensure that the underlying assumptions are systematically explored and that the risks (and benefits) of pooling and indirectly comparing treatment effects from RCTs for a particular research question are transparent.

Fatigue is an important problem in paediatric cancer patients and yoga may be an effective intervention. The primary objective was to determine the feasibility of individualized yoga for hospitalized children receiving intensive chemotherapy. We included English-speaking children and adolescents aged 7-18 years receiving intensive chemotherapy or haematopoietic stem cell transplantation (HSCT). Yoga was conducted three times weekly for three weeks. The primary outcome was feasibility, defined as ability to deliver at least 60% of planned sessions. Secondary outcomes were parent-reported Pediatric Quality of Life Inventory (PedsQL) Multidimensional Fatigue Scale, Fatigue Scale-Parent, PedsQL Generic Core Scales and PedsQL Acute Cancer Module. Between January and October 2013, 11 patients were enrolled. Median age was 14.0 (range 7.7-16.4) years and 6 (55%) were boys. Yoga was feasible with 10/11 participants meeting the threshold for feasibility. The median number of yoga sessions was 9 (range 3-13). No adverse events were attributed to yoga. Mean±standard deviation for the day 21 proxy-reported PedsQL general fatigue scores was 55.6±15.5. Qualitative comments suggested design changes for future yoga studies. Individualized yoga is feasible for inpatient children receiving intensive chemotherapy. Future work will include development and conduct of a randomized trial for fatigue amelioration.

Communication problems between family surrogates and intensive care unit (ICU) clinicians have been documented, but few interventions are effective. Nurses have the potential to play an expanded role in ICU communication and decision making. To conduct a pilot randomized controlled trial of the family navigator (FN), a distinct nursing role to address family members' unmet communication needs early in an ICU stay. An interprofessional team developed the FN protocol. A randomized controlled pilot intervention trial of the FN was performed in a tertiary referral hospital's ICU to test the feasibility and acceptability of the intervention. The intervention addressed informational and emotional communication needs through daily contact by using structured clinical updates, emotional and informational support modules, family meeting support, and follow-up phone calls. Twenty-six surrogate/patient pairs (13 per study arm) were enrolled. Surrogates randomized to the intervention had contact with the FN on 90% or more of eligible patient days. All surrogates agreed that they would recom mend the FN to other families. Open-ended comments from both surrogates and clinicians were uniformly positive. Having a fully integrated nurse empowered to facilitate decision making is a feasible intervention in an ICU and is well-received by ICU families and staff. A larger randomized controlled trial is needed to demonstrate impact on important outcomes, such as surrogates' well-being and decision quality. ©2016 American Association of Critical-Care Nurses.

To assess the feasibility of a mobile health, inhaled corticosteroid (ICS) adherence reminder intervention and to characterize adherence trajectories immediately following severe asthma exacerbation in high-risk urban children with persistent asthma. Children aged 2-13 with persistent asthma were enrolled in this pilot randomized controlled trial during an asthma emergency department (ED) visit or hospitalization. Intervention arm participants received daily text message reminders for 30 days, and both arms received electronic sensors to measure ICS use. Primary outcomes were feasibility of sensor use and text message acceptability. Secondary outcomes included adherence to prescribed ICS regimen and 30-day adherence trajectories. Group-based trajectory modeling was used to examine adherence trajectories. Forty-one participants (mean age 5.9) were randomized to intervention (n = 21) or control (n = 20). Overall, 85% were Black, 88% had public insurance, and 51% of the caregivers had a high school education or less. Thirty-two participant families (78%) transmitted medication adherence data; of caregivers who completed the acceptability survey, 25 (96%) chose to receive daily reminders beyond that study interval. Secondary outcome analyses demonstrated similar average daily adherence between groups (intervention = 36%; control = 32%, P = 0.73). Three adherence trajectories were identified with none ever exceeding 80% adherence. Within a high-risk pediatric cohort, electronic monitoring of ICS use and adherence reminders delivered via text message were feasible for most participants, but there was no signal of effect. Adherence trajectories following severe exacerbation were suboptimal, demonstrating an important opportunity for asthma care improvement.

To evaluate the feasibility and potential efficacy of an age-appropriate additional parenting intervention for very preterm born toddlers. In a randomized controlled pilot study, 60 of 94 eligible very preterm born children who had received a responsive parenting intervention in their first year were randomized to usual care or the additional intervention, consisting of 4-6 home visits between 18 and 22 months' corrected gestational age (CA). Parents were supported to responsively interact during increasingly complex daily activities and play. Parental satisfaction with the intervention was evaluated with a questionnaire. At baseline and 24 months CA, parents completed the Infant Toddler Social and Emotional Assessment, the Ages and Stages Questionnaire, and the Dutch Schlichting Lexilist for receptive language. At 24 months CA, motor, and cognitive development was measured by the Bayley Scales of Infant and Toddler Development, Third Edition Dutch version, and parent-child interaction was evaluated by the Emotional Availability Scales. Parental compliance and satisfaction with the intervention was high. Effect sizes (after correction for baseline variables) were small for internalizing and competence behavior, receptive language, and problem solving; medium for cognitive development and parent-child interaction; and large for externalizing and dysregulation behavior and motor development. After a postdischarge intervention during the first year, an additional responsive parenting support at toddler-age is feasible and associated with positive outcomes in a broad array of parental and child outcome measures. www.toetsingonline.nl: NL40208.018.12.

To determine the feasibility and pilot a sleep education program in New Zealand high school students. A parallel, two-arm randomized controlled pilot trial was conducted. High school students (13 to 16 years) were randomly allocated to either a classroom-based sleep education program intervention (n = 15) or to a usual curriculum control group (n = 14). The sleep education program involved four 50-minute classroom-based education sessions with interactive groups. Students completed a 7-day sleep diary, a sleep questionnaire (including sleep hygiene, knowledge and problems) at baseline, post-intervention (4 weeks) and 10 weeks follow-up. An overall treatment effect was observed for weekend sleep duration (F 1,24 = 5.21, p = 0.03). Participants in the intervention group slept longer during weekend nights at 5 weeks (1:37 h:min, p = 0.01) and 10 weeks: (1:32 h:min, p = 0.03) compared to those in the control group. No differences were found between groups for sleep duration on weekday nights. No significant differences were observed between groups for any of the secondary outcomes (sleep hygiene, sleep problems, or sleep knowledge). A sleep education program appears to increase weekend sleep duration in the short term. Although this program was feasible, most schools are under time and resource pressure, thus alternative methods of delivery should be assessed for feasibility and efficacy. Larger trials of longer duration are needed to confirm these findings and determine the sustained effect of sleep education on sleep behavior and its impact on health and psychosocial outcomes.

A yoga intervention for type 2 diabetes risk reduction: a pilot randomized controlled trial
2014-01-01
Background Type 2 diabetes is a major health problem in many countries including India. Yoga may be an effective type 2 diabetes prevention strategy in India, particularly given its cultural familiarity. Methods This was a parallel, randomized controlled pilot study to collect feasibility and preliminary efficacy data on yoga for diabetes risk factors among people at high risk of diabetes. Primary outcomes included: changes in BMI, waist circumference, fasting blood glucose, postprandial blood glucose, insulin, insulin resistance, blood pressure, and cholesterol. We also looked at measures of psychological well-being including changes in depression, anxiety, positive and negative affect and perceived stress. Forty-one participants with elevated fasting blood glucose in Bangalore, India were randomized to either yoga (n = 21) or a walking control (n = 20). Participants were asked to either attend yoga classes or complete monitored walking 3–6 days per week for eight weeks. Randomization and allocation was performed using computer-generated random numbers and group assignments delivered in sealed, opaque envelopes generated by off-site study staff. Data were analyzed based on intention to treat. Results This study was feasible in terms of recruitment, retention and adherence. In addition, yoga participants had significantly greater reductions in weight, waist circumference and BMI versus control (weight −0.8 ± 2.1 vs. 1.4 ± 3.6, p = 0.02; waist circumference −4.2 ± 4.8 vs. 0.7 ± 4.2, p < 0.01; BMI −0.2 ± 0.8 vs. 0.6 ± 1.6, p = 0.05). There were no between group differences in fasting blood glucose, postprandial blood glucose, insulin resistance or any other factors related to diabetes risk or psychological well-being. There were significant reductions in systolic and diastolic blood pressure, total cholesterol, anxiety, depression, negative affect and perceived stress in both the yoga intervention and walking control over the course of the study. Conclusion Among Indians with elevated fasting blood glucose, we found that participation in an 8-week yoga intervention was feasible and resulted in greater weight loss and reduction in waist circumference when compared to a walking control. Yoga offers a promising lifestyle intervention for decreasing weight-related type 2 diabetes risk factors and potentially increasing psychological well-being.

Study Design A pilot double-blind randomized controlled trial (RCT). Background The effectiveness of physical therapy for femoroacetabular impingement syndrome (FAIS) is unknown. Objectives To determine the feasibility of an RCT investigating the effectiveness of a physical therapy intervention for FAIS. Methods Participants were 17 women and 7 men (mean ± SD age, 37 ± 8 years; body mass index, 25.4 ± 3.4 kg/m 2 ) with FAIS who received physical therapy interventions provided over 12 weeks. The FAIS-specific physical therapy group received personalized progressive strengthening and functional retraining. The control group received standardized stretching exercises. In addition, both groups received manual therapy, progressive physical activity, and education. The primary outcome was feasibility, including integrity of the protocol, recruitment and retention, outcome measures, randomization procedure, and sample-size estimate. Secondary outcomes included hip pain and function (international Hip Outcome Tool-33 [iHOT-33]) and hip muscle strength. Poststudy interviews were conducted to determine potential improvements for future studies. Results Twenty-four (100%) patients with known eligibility agreed to participate. Four patients (17%) were lost to follow-up. All participants and the tester remained blinded, and the control intervention was acceptable to participants. The between-group mean differences in change scores were 16 (95% confidence interval [CI]: -9, 38) for the iHOT-33 and 0.24 (95% CI: 0.02, 0.47) Nm/kg for hip adduction strength, favoring the FAIS-specific physical therapy group. Using an effect size of 0.61, between-group improvements for the iHOT-33 suggest that 144 participants are required for a full-scale RCT. Conclusion A full-scale RCT of physical therapy for FAIS is feasible. A FAIS-specific physical therapy program has the potential for a moderate to large positive effect on hip pain, function, and hip adductor strength. Level of Evidence Therapy, level 2b.

Abstract Objectives The study objectives were to ascertain whether a novel educational film class is an acceptable and feasible comparison group for a randomized controlled trial regarding the effects of an active mind–body therapy on cardiovascular disease risk in postmenopausal women. Methods Seventy-five (75) participants attended a baseline assessment visit and were randomly assigned to either a yoga group or an educational film (control) group. Both groups attended two 90-minute classes/week for 8 weeks, followed by a second assessment visit. Those not attending the second assessment were classified as dropouts. Over 60 films covering a range of topics relevant to the study population were evaluated; 15 were selected by consensus of at least 2 researchers and 1 layperson. Each film session followed the same format: an informal greeting period, viewing of the film, and a 15-minute postfilm discussion. To determine acceptability and feasibility of the film class, potential between-group differences in dropout and attendance were examined, and participant feedback given during class and on end-of-study questionnaires were evaluated. Results The relation between group assignment and dropout was not significant (χ2 [1, N = 75] = 0.14, p = 0.71). One-way analysis of variance (ANOVA) indicated no significant between-group difference in number of classes attended for the yoga (X = 13.67 ± 3.10) versus film group (13.26 ± 1.97), F(1,63) = 0.39, p = 0.53). Participant feedback regarding the film program was positive. Conclusions These findings support the feasibility and acceptability of this educational film control. Easy to standardize and tailor to a variety of populations, this film program may offer an attractive alternative to the more traditional educational control. PMID:21554109

Deprescribing is a suggested intervention to reverse the potential iatrogenic harms of inappropriate polypharmacy. The review aimed to determine whether or not deprescribing is a safe, effective and feasible intervention to modify mortality and health outcomes in older adults. Specified databases were searched from inception to February 2015. Two researchers independently screened all retrieved articles for inclusion, assessed study quality and extracted data. Data were pooled using RevMan v5.3. Eligible studies included those where older adults had at least one medication deprescribed. The primary outcome was mortality. Secondary outcomes were adverse drug withdrawal events, psychological and physical health outcomes, quality of life, and medication usage (e.g. successful deprescribing, number of medications prescribed, potentially inappropriate medication use). A total of 132 papers met the inclusion criteria, which included 34 143 participants aged 73.8 ± 5.4 years. In nonrandomized studies, deprescribing polypharmacy was shown to significantly decrease mortality (OR 0.32, 95% CI: 0.17-0.60). However, this was not statistically significant in the randomized studies (OR 0.82, 95% CI 0.61-1.11). Subgroup analysis revealed patient-specific interventions to deprescribe demonstrated a significant reduction in mortality (OR 0.62, 95% CI 0.43-0.88). However, generalized educational programmes did not change mortality (OR 1.21, 95% CI 0.86-1.69). Although nonrandomized data suggested that deprescribing reduces mortality, deprescribing was not shown to alter mortality in randomized studies. Mortality was significantly reduced when applying patient-specific interventions to deprescribe in randomized studies. © 2016 The British Pharmacological Society.

The objective of this investigation was to assess the feasibility of a culturally tailored care management intervention for physically injured American Indian/Alaska Native (AI/AN) patients. The intervention was initiated at a Level I trauma center and aimed to link AI/AN patients to their distant tribal communities. Thirty AI/AN patients were randomized to the intervention or to usual care. Assessments at baseline, 3 months, and 6 months included self-reported lifetime cumulative trauma burden, Native healing requests, and symptoms of posttraumatic stress, depression, and alcohol use. Generalized estimating equations ascertained differences between groups over time. Ninety-four percent of eligible patients participated; follow-up at 3 and 6 months was 83%. Participants had high numbers of lifetime traumas (mean = 5.1, standard deviation = 2.6). No differences between the intervention and control groups were observed in posttraumatic stress symptoms, depression symptoms, or alcohol use at baseline or follow-up time points. Among intervention patients, 60% either requested or participated in traditional Native healing practices and 75% reported that the intervention was helpful. This effectiveness trial demonstrated the feasibility of recruiting and randomizing injured AI/AN patients. Future efforts could integrate evidence-based interventions and traditional Native healing into stepped collaborative care treatment programs. PMID:22168295

We describe the development, feasibility, and acceptability of a novel preventive intervention for depression in African American girls living in urban poverty. Our approach targeted individual and interpersonal vulnerabilities that have been shown to confer risk for depression in samples of African American girls living in low-income, urban settings, including suppression of negative emotion and lack of assertiveness with peers, memory for positive emotion, active coping, and family connection. Focus groups and an open trial were conducted to refine the goals and mechanisms for skill building. A randomized controlled trial (RCT) of the new program (Cities Mother-Daughter Project) was conducted with 3rd-5th grade students from Chicago Public Schools (CPS). Three cycles of screening, randomization, and deployment were conducted to assess feasibility, satisfaction, and usability. Results indicate that feasibility was weak; whereas, satisfaction and usability were high. Future directions for testing efficacy are discussed.

We evaluated the feasibility of DBT training, adherence, and retention preparing for a randomized controlled trial of Dialectical Behavior Therapy (DBT) adapted for Norwegian adolescents engaging in self-harming behavior and diagnosed with features of borderline personality disorder. Therapists were intensively trained and evaluated for adherence. Adherence scores, treatment retention, and present and previous self-harm were assessed. Twenty-seven patients were included (mean age 15.7 years), all of them with recent self-harming behaviors and at least 3 features of Borderline Personality Disorder. Therapists were adherent and 21 (78%) patients completed the whole treatment. Three subjects reported self-harm at the end of treatment, and urges to self-harm decreased. At follow up, 7 of 10 subjects reported no self-harm. DBT was found to be well accepted and feasible. Randomized controlled trials are required to test the effectiveness of DBT for adolescents.

The feasibility of using a two-microphone, random-excitation technique for the measurement of acoustic impedance was studied. Equations were developed, including the effect of mean flow, which show that acoustic impedance is related to the pressure ratio and phase difference between two points in a duct carrying plane waves only. The impedances of a honeycomb ceramic specimen and a Helmholtz resonator were measured and compared with impedances obtained using the conventional standing-wave method. Agreement between the two methods was generally good. A sensitivity analysis was performed to pinpoint possible error sources and recommendations were made for future study. The two-microphone approach evaluated in this study appears to have some advantages over other impedance measuring techniques.

The purpose of this trial was to examine the feasibility and efficacy of computerized cognitive exercises from Scientific Brain Training (SBT), compared to the computer game Tetris as an active placebo, in a pilot study of adolescents with attention-deficit/hyperactivity disorder (ADHD). Eighteen adolescents with ADHD were randomized to treatment or control intervention for 7 weeks. Outcome measures were cognitive test, symptom, and motivation questionnaires. SBT and Tetris were feasible as home-based interventions, and participants' compliance was high, but participants perceived both interventions as not very interesting or helpful. There were no significant group differences on cognitive and ADHD-symptom measures after intervention. Pre-post intra-group measurement showed that the SBT had a significant beneficial effect on sustained attention, while the active placebo had significant beneficial effects on working memory, both with large effect sizes. Although no significant differences were found between groups on any measure, there were significant intra-group changes for each group.

To evaluate the feasibility of predictable or unpredictable amplitude-modulated sounds for tinnitus therapy. The study consisted of two parts. (1) An adaptation experiment. Loudness level matches and rating scales (10-point) for loudness and distress were obtained at a silent baseline and at the end of three counterbalanced 30-min exposures (silence, predictable and unpredictable). (2) A qualitative 2-week sound therapy feasibility trial. Participants took home a personal music player (PMP). Part 1: 23 individuals with chronic tinnitus and part 2: seven individuals randomly selected from Part 1. Self-reported tinnitus loudness and annoyance were significantly lower than baseline ratings after acute unpredictable sound exposure. Tinnitus annoyance ratings were also significantly lower than the baseline but the effect was small. The feasibility trial identified that participant preferences for sounds varied. Three participants did not obtain any benefit from either sound. Three participants preferred unpredictable compared to predictable sounds. Some participants had difficulty using the PMP, the average self-report hours of use were low (less <1 h/day). Unpredictable surf-like sounds played using a PMP is a feasible tinnitus treatment. Further work is required to improve the acceptance of the sound and ease of PMP use.
Feasibility of group intervention for bereaved siblings after pediatric cancer death.

This study evaluated the feasibility (acceptability, recruitment, retention rates, treatment fidelity, and outcome measures) of implementing a manualized group intervention for bereaved siblings after pediatric cancer death. A convenience sample of 10 siblings participated. The intervention consisted of eight 2-hour sessions that focused on strategies for coping with grief, relationships, and emotional growth. Positive outcomes were obtained with respect to acceptability, recruitment, retention rates, and treatment fidelity. Preliminary outcomes were mixed. Parent pre- and post-intervention outcomes suggested improvements in siblings' overall emotional and social quality of life. Siblings' self-reports reflected no improvements. These data support the feasibility of conducting this intervention and suggest beneficial outcomes based on parental reports. Further research is recommended to evaluate the group intervention efficacy with a large sample using a randomized controlled trial to address the needs of bereaved siblings.

Communication problems impede effective symptom management during chemotherapy. The primary aim of this pilot randomized controlled trial was to test the effects of a personal digital assistant-delivered communication intervention on pain, depression, and fatigue symptoms among breast cancer patients undergoing chemotherapy. Secondary aims included assessment of 1) study feasibility, 2) patient and clinician responses to study participation, and 3) intervention effects on health-related quality of life (HRQoL) and communication self-efficacy. Intervention group participants (n = 27) completed symptom inventories at baseline, once per week during treatment, and at posttreatment. Depending on symptom severity, they viewed race-concordant videos on how to communicate about pain, depression and/or fatigue, using the personal digital assistant. Symptom records were tracked and shared with clinicians. Control group participants (n = 23) received usual care. Longitudinal random effects modeling assessed the changes in average symptom scores over time. Descriptive statistics assessed study feasibility and intervention effects on HRQoL and communication self-efficacy. Postintervention focus groups, interviews, and surveys assessed responses to study participation. Mean age of the participants was 51.0 years; 42 participants (84%) were white. In comparison with control, intervention group participants reported lower average pain severity over time (P = .015). Mean pain interference scores over time were marginally different between groups (P = .07); mean depression and fatigue scores over time were statistically nonsignificant. Feasibility outcomes and perspectives about study participation were positive. Mean pre-post decreases in HRQoL were generally higher among intervention group participants; pre-post changes in communication self-efficacy were equivalent. Mixed findings of the study indicate the need for future research.

Abstract Objectives The study objectives were to determine the feasibility and effects of providing therapeutic massage at home for patients with metastatic cancer. Design This was a randomized controlled trial. Settings/location Patients were enrolled at Oncology Clinics at a large urban academic medical center; massage therapy was provided in patients' homes. Subjects Subjects were patients with metastatic cancer. Interventions There were three interventions: massage therapy, no-touch intervention, and usual care. Outcome measures Primary outcomes were pain, anxiety, and alertness; secondary outcomes were quality of life and sleep. Results In this study, it was possible to provide interventions for all patients at home by professional massage therapists. The mean number of massage therapy sessions per patient was 2.8. A significant improvement was found in the quality of life of the patients who received massage therapy after 1-week follow-up, which was not observed in either the No Touch control or the Usual Care control groups, but the difference was not sustained at 1 month. There were trends toward improvement in pain and sleep of the patients after therapeutic massage but not in patients in the control groups. There were no serious adverse events related to the interventions. Conclusions The study results showed that it is feasible to provide therapeutic massage at home for patients with advanced cancer, and to randomize patients to a no-touch intervention. Providing therapeutic massage improves the quality of life at the end of life for patients and may be associated with further beneficial effects, such as improvement in pain and sleep quality. Larger randomized controlled trials are needed to substantiate these findings. PMID:23368724

The objectives of this pilot study were to assess the feasibility of recruitment and adherence to an eight-session mindfulness meditation program for community-dwelling older adults with chronic low back pain (CLBP) and to develop initial estimates of treatment effects. It was designed as a randomized, controlled clinical trial. Participants were 37 community-dwelling older adults aged 65 years and older with CLBP of moderate intensity occurring daily or almost every day. Participants were randomized to an 8-week mindfulness-based meditation program or to a wait-list control group. Baseline, 8-week and 3-month follow-up measures of pain, physical function, attention, and quality of life were assessed. Eighty-nine older adults were screened and 37 found to be eligible and randomized within a 6-month period. The mean age of the sample was 74.9 years, 21/37 (57%) of participants were female and 33/37 (89%) were white. At the end of the intervention 30/37 (81%) participants completed 8-week assessments. Average class attendance of the intervention arm was 6.7 out of 8. They meditated an average of 4.3 days a week and the average minutes per day was 31.6. Compared to the control group, the intervention group displayed significant improvement in the Chronic Pain Acceptance Questionnaire Total Score and Activities Engagement subscale (P = .008, P = .004) and SF-36 Physical Function (P = .03). An 8-week mindfulness-based meditation program is feasible for older adults with CLBP. The program may lead to improvement in pain acceptance and physical function. PMID:17544212
A randomized pilot trial of a full subsidy vs. a partial subsidy for obesity treatment.

Intensive obesity treatment is mandated by federal health care reform but is costly. A partial subsidy for obesity treatment could lower the cost of treatment, without reducing its efficacy. This study sought to test whether a partial subsidy for obesity treatment would be feasible, as compared to a fully subsidized intervention. The study was a pilot randomized trial. Participants (n = 50) were primary care patients with obesity and at least one comorbid condition (diabetes, hypertension, dyslipidemia, or obstructive sleep apnea). Each participant received eight weight loss counseling visits as well as portion-controlled foods for weight loss. Participants were randomized to full subsidy or partial subsidy (2 vs. 1 meal per day provided). The primary outcome was weight change after 4 months. Secondary outcomes included changes in blood pressure, waist circumference, and health-related quality of life. Participants in the full and partial subsidy groups lost 5.9 and 5.3 kg, equivalent to 5.3% and 5.1% of initial weight, respectively (P = 0.71). Changes in secondary outcomes were similar in the two groups. A partial subsidy was feasible and induced a clinically similar amount of weight loss, compared to a full subsidy. Large-scale testing of economic incentives for weight control is merited given the federal mandate to offer weight loss counseling to obese patients.

Acute chest syndrome (ACS) is defined as fever, respiratory symptoms and a new pulmonary infiltrate in an individual with sickle cell disease (SCD). Nearly half of ACS episodes occur in SCD patients already hospitalized, potentially permitting pre-emptive therapy in high-risk patients. Simple transfusion of red blood cells may abort ACS if given to patients hospitalized for pain who develop fever and elevated levels of secretory phospholipase A2 (sPLA2). In a feasibility study (PROACTIVE; ClinicalTrials.gov NCT00951808), patients hospitalized for pain who developed fever and elevated sPLA2 were eligible for randomization to transfusion or observation; all others were enrolled in an observational arm. Of 237 enrolled, only 10 were randomized; one of the four to receive transfusion had delayed treatment. Of 233 subjects receiving standard care, 22 developed ACS. A threshold level of sPLA2 ≥ 48 ng/ml gave optimal sensitivity (73%), specificity (71%) and accuracy (71%), but a positive predictive value of only 24%. The predictive value of sPLA2 was improved in adults and patients with chest or back pain, lower haemoglobin concentration and higher white blood cell counts; and those receiving less than two-thirds maintenance fluids. The hurdles identified in PROACTIVE should facilitate design of a larger, definitive, phase 3 randomized controlled trial. PMID:22463614

The evidence base for treatment of bipolar affective disorder (BD) demands the evaluation of new psychotherapies in order to broaden patient choice. This study reports on the feasibility, safety, helpfulness and effectiveness of cognitive analytic therapy (CAT). In a pilot randomized controlled trial, BD patients in remission were randomized to either receiving 24 sessions of CAT (n = 9) or treatment as usual (n = 9) and were assessed in terms of symptoms, functioning and service usage over time. In the CAT arm no adverse events occurred, 8/9 completed treatment, 5/8 attended all 24 sessions and 2/8 were categorized as recovered. The most common helpful event during CAT was recognition of patterns in mood variability, with helpfulness themes changing according to phase of therapy. No major differences were found when comparing the arms over time in terms of service usage or psychometric outcomes. The study suggests that conducting further research into the effectiveness of CAT in treating BD is warranted and guidance regarding future trials is provided. Copyright © 2016 John Wiley & Sons, Ltd. Treating BD with CAT appears feasible and safe. Retaining fidelity to the reformulation, recognition and revision structure of CAT appears useful. Participants stated that across the phases of CAT, focussing on patterns of mood variability was consistently helpful. Copyright © 2016 John Wiley & Sons, Ltd.

Being obese and drinking more than 14 units of alcohol per week places men at very high risk of developing liver disease. This study assessed the feasibility of a trial to reduce alcohol consumption. It tested the recruitment strategy, engagement with the intervention, retention and study acceptability. Men aged 35-64 years who drank >21 units of alcohol per week and had a BMI > 30 were recruited by two methods: from GP patient registers and by community outreach. The intervention was delivered by a face to face session followed by a series of text messages. Trained lay people (Study Coordinators) delivered the face to face session. Participants were followed up for 5 months from baseline to measure weekly alcohol consumption and BMI. The recruitment target of 60 was exceeded, with 69 men recruited and randomized. At baseline, almost all the participants (95%) exceeded the threshold for a 19-fold increase in the risk of dying from liver disease. The intervention was delivered with high fidelity. A very high follow-up rate was achieved (98%) and the outcomes for the full trial were measured. Process evaluation showed that participants responded as intended to key steps in the behaviour change strategy. The acceptability of the study methods was high: e.g. 80% of men would recommend the study to others. This feasibility study identified a group at high risk of liver disease. It showed that a full trial could be conducted to test the effectiveness and cost-effectiveness of the intervention. Current controlled trials: ISRCTN55309164. National Institute for Health Research Health Technology Assessment (NIHR HTA). This feasibility study recruited 69 men at high risk of developing liver disease. The novel intervention, to reduce alcohol consumption through the motivation of weight loss, was well received. A very high follow-up rate was achieved. Process evaluation showed that participants engaged with key components of the behaviour change strategy. © The Author 2017. Medical Council on Alcohol and Oxford University Press.

Hearing loss (HL) is a disability associated with poorer health-related quality of life including an increased risk for loneliness, isolation, functional fitness declines, falls, hospitalization and premature mortality. The purpose of this pilot trial is to determine the feasibility and acceptability of a novel intervention to reduce loneliness, improve functional fitness, social connectedness, hearing and health-related quality of life in older adults with HL. This 10-week, single-blind, pilot randomized control trial (RCT) will include a convenience sample of ambulatory adults aged 65 years or older with self-reported HL. Following baseline assessments, participants will be randomized to either intervention (exercise, health education, socialization and group auditory rehabilitation (GAR)) or control (GAR only) groups. The intervention group will attend a local YMCA twice a week and the control group once a week. Intervention sessions will include 45 min of strengthening, balance and resistance exercises, 30 min of group walking at a self-selected pace and 60 min of interactive health education or GAR. The control group will attend 60-min GAR sessions. GAR sessions will include education about hearing, hearing technologies, enhancing communication skills, and psychosocial support. Pre-post trial data collection and measures will include: functional fitness (gait speed, 30-s Sit to Stand Test), hearing and health-related quality of life, loneliness, depression, social participation and social support. At trial end, feasibility (recruitment, randomization, retention, acceptability) and GAR will be evaluated. Despite evidence suggesting that HL is associated with declines in functional fitness, there are no studies aimed at addressing functional fitness declines associated with the disability of HL. This pilot trial will provide knowledge about the physical, mental and social impacts on health related to HL as a disability. This will inform the feasibility of a larger RCT and preliminary evidence about the initial effects of a novel, community-based, holistic intervention addressing both the negative psychosocial and functional physical effects of HL among older adults.

Choline, an essential nutrient, serves as a methyl-group donor for DNA methylation and is a constituent of the neurotransmitter acetylcholine and a precursor to major components of cell membranes. Findings from animal studies suggest that choline supplementation during pregnancy may mitigate adverse effects of prenatal alcohol exposure on growth and neurocognitive function. We conducted a randomized, double-blind exploratory trial to examine feasibility and acceptability of a choline supplementation intervention during pregnancy. 70 heavy drinkers, recruited in mid-pregnancy, were randomly assigned to receive a daily oral dose of 2g of choline or a placebo from time of enrollment until delivery. Each dose consisted of an individually wrapped packet of powder that, when mixed with water, produced a sweet tasting grape-flavored drink. Adherence was assessed by collecting used and unused drink packets on a monthly basis and tabulating the number used. Side effects were assessed in monthly interviews. Blood samples obtained at enrollment and at 4 and 12 weeks after randomization were assayed for plasma choline concentration. Adherence was good-to-excellent (median doses taken=74.0%; interquartile range=53.9-88.7%) and was not related to a range of sociodemographic characteristics or to alcohol consumption ascertained using a timeline follow-back interview. By 4 weeks, plasma choline concentrations were significantly higher in the choline supplementation than the placebo arm, and this group difference continued to be evident at 12 weeks. The only side effect was a small increase in nausea/dyspepsia. No effects were seen for diarrhea, vomiting, muscle stiffness, blood pressure, or body odor changes. This study demonstrated that a choline supplementation program with very heavy drinkers during pregnancy is feasible even among highly disadvantaged, poorly educated women. The broad acceptability of this intervention is indicated by our finding that adherence was not related to maternal education, intellectual function, depression, nutritional status, or alcohol use.

Therapeutic hypothermia is the standard of care after perinatal asphyxia. Preclinical studies show 50% xenon improves outcome, if started early. During a 32-patient study randomized between hypothermia only and hypothermia with xenon, 5 neonates were given xenon during retrieval using a closed-circuit incubator-mounted system. Without xenon availability during retrieval, 50% of eligible infants exceeded the 5-hour treatment window. With the transportable system, 100% were recruited. Xenon delivery lasted 55 to 120 minutes, using 174 mL/h (117.5-193.2) (median [interquartile range]), after circuit priming (1300 mL). Xenon delivery during ambulance retrieval was feasible, reduced starting delays, and used very little gas.

Art psychotherapy has greater potential for use with adults with mild to moderate learning disabilities as it places less of a burden on verbal interaction to achieve positive therapeutic, psychological, and behavioural goals. The feasibility study objectives include testing procedures, outcomes, validated tools, recruitment and attrition rates, acceptability, and treatment fidelity for manualised interpersonal art psychotherapy. Adult males and females with mild to moderate learning disabilities will be recruited from four NHS secure hospitals. Twenty patients will be recruited and randomly assigned to one of two treatment groups: fifteen 1-h individual sessions of manualised interpersonal art psychotherapy, or a treatment as usual waiting list control group. The Modified Overt Aggression Scale will be administered to both treatment arms. Four patients will be recruited to a single-case design component of the study exploring the acceptability of an attentional condition. This multi-site study will assist in future trial planning and inform feasibility including, procedures, treatment acceptability, therapist adherence, and estimation of samples size for a definitive RCT.

The use of the quasi-random band model in evaluating upwelling atmospheric radiation is investigated. The spectral transmittance and total band adsorptance are evaluated for selected molecular bands by using the line by line model, quasi-random band model, exponential sum fit method, and empirical correlations, and these are compared with the available experimental results. The atmospheric transmittance and upwelling radiance were calculated by using the line by line and quasi random band models and were compared with the results of an existing program called LOWTRAN. The results obtained by the exponential sum fit and empirical relations were not in good agreement with experimental results and their use cannot be justified for atmospheric studies. The line by line model was found to be the best model for atmospheric applications, but it is not practical because of high computational costs. The results of the quasi random band model compare well with the line by line and experimental results. The use of the quasi random band model is recommended for evaluation of the atmospheric radiation.

Given the critical role of parental care for pediatric cancer patients, this pilot study evaluated the feasibility and effectiveness of a hospital-based solution-focused brief therapy (SFBT) intervention for reducing psychological distress among parents of pediatric cancer patients in China. Differences between treatment and active control (AC) groups were assessed on dimensions of psychological distress. Parents' level of hope was also assessed. Participants (N = 44) were randomly assigned to SFBT or AC. Parents received four sessions of SFBT twice a week delivered by graduate-level hospital social workers. Pre- and post-intervention assessments measured change in distress (depression, anxiety, and somatization symptoms) of parents as well as their level of hope. Analysis of covariance (ANCOVA) indicated the SFBT group had better outcomes than the AC group on overall distress of somatic, anxiety, depression symptoms and level of hope. Within- and between-group treatment effects reported significantly greater effect of the SFBT group than of the AC group. Considering the inherent limits of a pilot feasibility study, results suggest that SFBT is a feasible, culturally compatible, and promising intervention for alleviating distress among Chinese parents of children with cancer. Additional comprehensive trials are needed to draw more definitive conclusions. SFBT may be beneficial for improving the critical support systems of parents of pediatric cancer patients. Thus, SFBT may have the potential to enhance children's well-being during cancer treatment and recovery.

Background Social networks are increasingly recognized as important points of intervention, yet relatively few intervention studies of respiratory infection transmission have utilized a network design. Here we describe the design, methods, and social network structure of a randomized intervention for isolating respiratory infection cases in a university setting over a 10-week period. Methodology/Principal Findings 590 students in six residence halls enrolled in the eX-FLU study during a chain-referral recruitment process from September 2012-January 2013. Of these, 262 joined as “seed” participants, who nominated their social contacts to join the study, of which 328 “nominees” enrolled. Participants were cluster-randomized by 117 residence halls. Participants were asked to respond to weekly surveys on health behaviors, social interactions, and influenza-like illness (ILI) symptoms. Participants were randomized to either a 3-Day dorm room isolation intervention or a control group (no isolation) upon illness onset. ILI cases reported on their isolation behavior during illness and provided throat and nasal swab specimens at onset, day-three, and day-six of illness. A subsample of individuals (N=103) participated in a sub-study using a novel smartphone application, iEpi, which collected sensor and contextually-dependent survey data on social interactions. Within the social network, participants were significantly positively assortative by intervention group, enrollment type, residence hall, iEpi participation, age, gender, race, and alcohol use (all P<0.002). Conclusions/Significance We identified a feasible study design for testing the impact of isolation from social networks in a university setting. These data provide an unparalleled opportunity to address questions about isolation and infection transmission, as well as insights into social networks and behaviors among college-aged students. Several important lessons were learned over the course of this project, including feasible isolation durations, the need for extensive organizational efforts, as well as the need for specialized programmers and server space for managing survey and smartphone data.

Background and study aims Barrett’s esophagus is a potentially pre-cancerous condition, affecting 375,000 people in the UK. Patients receive a 2-yearly endoscopy to detect cancerous changes, as early detection and treatment results in better outcomes. Current treatment requires random mapping biopsies along the length of Barrett’s, in addition to biopsy of visible abnormalities. As only 13 % of pre-cancerous changes appear as visible nodules or abnormalities, areas of dysplasia are often missed. Acetic acid chromoendoscopy (AAC) has been shown to improve detection of pre-cancerous and cancerous tissue in observational studies, but no randomized controlled trials (RCTs) have been performed to date. Patients and methods A “tandem” endoscopy cross-over design. Participants will be randomized to endoscopy using mapping biopsies or AAC, in which dilute acetic acid is sprayed onto the surface of the esophagus, highlighting tissue through an whitening reaction and enhancing visibility of areas with cellular changes for biopsy. After 4 to 10 weeks, participants will undergo a repeat endoscopy, using the second method. Rates of recruitment and retention will be assessed, in addition to the estimated dysplasia detection rate, effectiveness of the endoscopist training program, and rates of adverse events (AEs). Qualitative interviews will explore participant and endoscopist acceptability of study design and delivery, and the acceptability of switching endoscopic techniques for Barrett's surveillance. Results Endoscopists’ ability to diagnose dysplasia in Barrett’s esophagus can be improved. AAC may offer a simple, universally applicable, easily-acquired technique to improve detection, affording patients earlier diagnosis and treatment, reducing endoscopy time and pathology costs. The ABBA study will determine whether a crossover “tandem” endoscopy design is feasible and acceptable to patients and clinicians and gather outcome data to power a definitive trial. PMID:29340297

Eczema is common in children and in the UK most cases are managed in primary care. The foundation of all treatment is the regular use of leave-on emollients to preserve and restore moisture to the skin. This not only improves comfort but may also reduce the need for rescue treatment for 'flares', such as topical corticosteroids. However, clinicians can prescribe many different types of emollient and there is a paucity of evidence to guide this choice. One reason for this may be the challenges of conducting a clinical trial: are parents or carers of young children willing to be randomly allocated an emollient and followed up for a meaningful amount of time? This is a single-centre feasibility study of a pragmatic, four-arm, single-masked, randomized trial. Children with eczema who are eligible (from 1 month to less than 5 years of age, not known to be sensitive or allergic to any of study emollients or their constituents) are recruited via their general practices. Participants are allocated Aveeno® lotion, Diprobase® cream, Doublebase® gel or Hydromol® ointment via a web-based system, using a simple randomization process in a 1:1:1:1 fashion. Researchers are masked to the study emollient. Participants are assessed at baseline and followed up for 3 months. Data are collected by daily diaries, monthly researcher visits and review of electronic medical records. Because this is a feasibility study, a formal sample size calculation for the estimation of treatment effectiveness has not be made but we aim to recruit 160 participants. Recruitment is on-going. At the end of the study, as well as being able to answer the question, 'Is it is possible to recruit and retain children with eczema from primary care into a four-arm randomized trial of emollients?', we will also have collected important data on the acceptability and effectiveness of four commonly used emollients.

Objective A randomized control pilot study was conducted with Black men who have sex with men (BMSM; N = 42) aged 18–30 years to examine the feasibility of implementing a video intervention delivered using Facebook to motivate HIV testing. Methods At baseline, participants were unaware of their HIV status and had not tested for HIV in the past 6 months, residing in Los Angeles County. The intervention content included topics such as social influence, HIV knowledge, stigma, HIV positive knowledge, and benefits of knowing one’s HIV status. Findings Logistic regression revealed that those receiving the video intervention were 7 times more likely to have tested for HIV than those in the control group at 6-week follow-up (odds ratio [OR] = 7.00, 95% confidence interval [1.72, 28.33], p = .006). Conclusion Data suggest that the intervention was feasible for motivating HIV testing. PMID:29276800

Declining incidence and spatial heterogeneity complicated the design of phase 3 Ebola vaccine trials during the tail of the 2013-16 Ebola virus disease (EVD) epidemic in West Africa. Mathematical models can provide forecasts of expected incidence through time and can account for both vaccine efficacy in participants and effectiveness in populations. Determining expected disease incidence was critical to calculating power and determining trial sample size. In real-time, we fitted, forecasted, and simulated a proposed phase 3 cluster-randomized vaccine trial for a prime-boost EVD vaccine in three candidate regions in Sierra Leone. The aim was to forecast trial feasibility in these areas through time and guide study design planning. EVD incidence was highly variable during the epidemic, especially in the declining phase. Delays in trial start date were expected to greatly reduce the ability to discern an effect, particularly as a trial with an effective vaccine would cause the epidemic to go extinct more quickly in the vaccine arm. Real-time updates of the model allowed decision-makers to determine how trial feasibility changed with time. This analysis was useful for vaccine trial planning because we simulated effectiveness as well as efficacy, which is possible with a dynamic transmission model. It contributed to decisions on choice of trial location and feasibility of the trial. Transmission models should be utilised as early as possible in the design process to provide mechanistic estimates of expected incidence, with which decisions about sample size, location, timing, and feasibility can be determined.

To evaluate the feasibility and preliminary efficacy of a Web-based tobacco treatment for persons living with HIV (PLWH). Prospective, randomized controlled trial. HIV-care center in the Bronx, New York. Eligibility criteria included HIV infection, current tobacco usage, interest in quitting, and access to a computer with internet. One hundred thirty-eight subjects enrolled, and 134 completed the study. Positively Smoke Free on the Web (PSFW), an 8-session, 7-week targeted tobacco treatment program for PLWH, was compared with standard care (brief advice to quit and self-help brochure). All subjects were offered nicotine patches. The main feasibility outcomes were number of sessions logged into, number of Web pages visited, number of interactive clicks, and total time logged in. The main efficacy outcome was biochemically verified, 7-day point prevalence abstinence 3 months after intervention. PSFW subjects logged into a mean of 5.5 of 8 sessions and 26.2 of 41 pages. They executed a mean of 10 interactive clicks during a mean total of 59.8 minutes logged in. Most required reminder phone calls to complete the sessions. Educational level, anxiety score, and home access of the Web site were associated with Web site usage. Ten percent of the PSFW group vs. 4.3% of controls achieved the abstinence end point. Among those who completed all 8 sessions, 17.9% were abstinent, and among women completers, 30.8% were abstinent. Web-based treatment is a feasible strategy for PLWH smokers, and preliminary findings suggest therapeutic efficacy.

This paper investigates the propagation of Rayleigh surface waves in structures with randomly distributed surface micro-cracks using numerical simulations. The results revealed a significant ultrasonic nonlinear effect caused by the surface micro-cracks, which is mainly represented by a second harmonic with even more distinct third/quadruple harmonics. Based on statistical analysis from the numerous results of random micro-crack models, it is clearly found that the acoustic nonlinear parameter increases linearly with micro-crack density, the proportion of surface cracks, the size of micro-crack zone, and the excitation frequency. This study theoretically reveals that nonlinear Rayleigh surface waves are feasible for use in quantitatively identifying the physical characteristics of surface micro-cracks in structures.

Low levels of academic engagement may impede students' acquisition of skills. Intervening on student behavior using group contingencies may be a feasible way to increase academic engagement during group instruction. The current study examined the effect of a randomized dependent group contingency on levels of academic engagement for second-grade participants receiving small-group reading and writing instruction. The results showed that a randomized dependent group contingency increased the academic engagement of primary participants and several of the other participants during small-group instruction. The findings also showed that high levels of academic engagement were maintained when common stimuli were present and the dependent group contingency was withdrawn. © 2016 Society for the Experimental Analysis of Behavior.

Active gaming technologies, including the Nintendo Wii and Xbox Kinect, have become increasingly popular for use in stroke rehabilitation. However, these systems are not specifically designed for this purpose and have limitations. The aim of this study was to investigate the feasibility of using a suite of motion-controlled games in individuals with stroke undergoing rehabilitation. Four games, which utilised a depth-sensing camera (PrimeSense), were developed and tested. The games could be played in a seated or standing position. Three games were controlled by movement of the torso and one by upper limb movement. Phase 1 involved consecutive recruitment of 40 individuals with stroke who were able to sit unsupported. Participants were randomly assigned to trial one game during a single session. Sixteen individuals from Phase 1 were recruited to Phase 2. These participants were randomly assigned to an intervention or control group. Intervention participants performed an additional eight sessions over four weeks using all four game activities. Feasibility was assessed by examining recruitment, adherence, acceptability and safety in both phases of the study. Forty individuals (mean age 63 years) completed Phase 1, with an average session time of 34 min. The majority of Phase 1 participants reported the session to be enjoyable (93 %), helpful (80 %) and something they would like to include in their therapy (88 %). Sixteen individuals (mean age 61 years) took part in Phase 2, with an average of seven 26-min sessions over four weeks. Reported acceptability was high for the intervention group and improvements over time were seen in several functional outcome measures. There were no serious adverse safety events reported in either phase of the study; however, a number of participants reported minor increases in pain. A post-stroke intervention using interactive motion-controlled games shows promise as a feasible and potentially effective treatment approach. This paper presents important recommendations for future game development and research to further explore long-term adherence, acceptability, safety and efficacy.

Objective Feasibility trials assess whether a behavior change program warrants a definite trial evaluation. This paper reports the feasibility of an intervention consisting of Self Determination Theory-informed text messages, pedometers, and goal prompts to increase adolescent physical activity. Methods A four-group randomized design with baseline and immediate post-study assessments was used. Groups (pedometer; pedometer + goal prompt; pedometer + goal prompt + theory-informed texts; no-treatment control) were systematically varied to assess the additive effect of intervention components on objectively-measured physical activity (ie, ActiGraph). The primary outcome of the 12-week intervention was program feasibility. Changes in average daily step counts and minutes of moderate-to-vigorous physical activity were also examined. Post-intervention research with a sub-set of participants examined program reactions. Results Participants (N = 160) were evenly split by sex, mostly 14-15 years old, and of diverse race/ethnicity. Feasibility criteria were met. Attrition rate was less than two percent. Modest increases in average daily step counts and moderate-to-vigorous physical activity were observed in all groups except the control group. Participants reported positive reactions to the intervention. Conclusions An intervention consisting of pedometers, theory-informed texts, and goal prompts, is a feasible and acceptable method for promoting physical activity to adolescents. PMID:27338994

Women of reproductive age diagnosed with cancer are often interested in preserving gametes or reproductive tissue that would allow for future genetic parenthood. Preservation of fertility is often accomplished in young cancer patients via ovarian stimulation followed by oocyte or embryo cryopreservation. Conventional stimulation protocols, however, require 2-4 weeks to complete ovarian stimulation, oocyte retrieval and possible fertilization. Such a strategy may not be feasible in patients requiring urgent cancer treatment. Recent studies have highlighted that random start ovarian stimulation can be initiated irrespective of the phase of the menstrual cycle and is an attractive alternative to conventional ovarian stimulation. The primary aim of the current review is to discuss the feasibility and success of random start ovarian stimulation for oocyte or embryo cryopreservation in women desiring fertility preservation prior to gonadotoxic cancer therapy. We performed a systematic review of medical literature published between January 2000 to June 2017 reporting the utility of random start ovarian stimulation for fertility preservation. Search terms included "fertility preservation," "cancer," "ovarian stimulation," "random-start ovarian stimulation," "embryo cryopreservation, and" "oocyte cryopreservation." Publications were included in this review only if patients underwent random start ovarian stimulation prior to cancer therapy. Nineteen publications were identified and perused by the authors. Most publications described the utility of random start ovarian stimulation in the setting of breast cancer. Radom-start stimulation was associated with a reduced time interval between ovarian stimulation initiation and oocyte or embryo cryopreservation. The yield of mature oocytes and their developmental potential into embryos was comparable between conventional and random-start protocols, albeit with higher gonadotropin doses in the latter. The current review suggests that random start ovarian stimulation can shorten the interval between ovarian stimulation and oocyte retrieval, with the yield of oocytes and embryos being comparable to conventional stimulation protocols. Thus, random start ovarian stimulation may serve as a better option for fertility preservation in patients requiring urgent cancer treatment.

Background Laparoscopy-assisted surgery, fast-track perioperative treatment are both increasingly used in colorectal cancer treatment, for their short-time benefits of enhanced recovery and short hospital stays. However, the benefits of the integration of the Laparoscopy-assisted surgery, fast-track perioperative treatment, and even with the Xelox chemotherapy, are still unknown. In this study, the three treatments integration is defined as "Fast Track Multi-Discipline Treatment Model" for colorectal cancer and this model extends the benefits to the whole treatment process of colorectal cancer. The main purpose of the study is to explore the feasibility of "Fast Track Multi-Discipline Treatment" model in treatment of colorectal cancer. Methods The trial is a prospective randomized controlled study with 2 × 2 balanced factorial design. Patients eligible for the study will be randomized to 4 groups: (I) Laparoscopic surgery with fast track perioperative treatment and Xelox chemotherapy; (II) Open surgery with fast track perioperative treatment and Xelox chemotherapy; (III) Laparoscopic surgery with conventional perioperative treatment and mFolfox6 chemotherapy; (IV) Open surgery with conventional perioperative treatment and mFolfox6 chemotherapy. The primary endpoint of this study is the hospital stays. The secondary endpoints are the quality of life, chemotherapy related adverse events, surgical complications and hospitalization costs. Totally, 340 patients will be enrolled with 85 patients in each group. Conclusions The study initiates a new treatment model "Fast Track Multi-Discipline Treatment" for colorectal cancer, and will provide feasibility evidence on the new model "Fast Track Multi-Discipline Treatment" for patients with colorectal cancer.

Physical and psychological challenges can arise from paediatric injury, which can impact child health outcomes. Evidence-based resources to promote recovery are limited. The low cost, portable Cellie Coping Kit for Children with Injury provides evidence-based strategies to help children manage injury-related challenges. This study aimed to describe intervention feasibility and explore initial outcomes (learning, quality of life [QOL], and trauma symptoms). Three independent pilot studies were conducted. Child-parent dyads (n = 61) participated in the intervention; ~36% completed a 4-week follow-up assessment. Results suggested that the intervention was feasible (e.g., 95% of parents would recommend the intervention; >85% reported that it was easy to use). Over 70% of participants reported learning new skills. No statistically significant differences were detected for children's QOL or trauma symptoms preintervention to postintervention. Preliminary research suggests that the Cellie Coping Kit for Children with Injuries is a feasible, low-cost, preventive intervention, which may provide families with strategies to promote recovery from paediatric injury. Future research, including a randomized controlled trial, ought to further examine targeted long-term intervention outcomes. © 2018 John Wiley & Sons Ltd.

Objective We evaluated the feasibility of a trial of Wii interactive video gaming, and its potential efficacy at improving cognitive functioning compared to health education, in a community sample of older adults with neuropsychologically defined mild cognitive impairment (MCI). Methods Twenty older adults were equally randomized to either group-based interactive video gaming or health education for 90 minutes each week for 24 weeks. Although the primary outcomes were related to study feasibility, we also explored the effect of the intervention on neuropsychological performance and other secondary outcomes. Results All 20 participants completed the intervention, and 18 attended at least 80% of the sessions. The majority (80%) of participants were “very much” satisfied with the intervention. Bowling was enjoyed by the most participants, and was also the rated highest among the games for mental, social and physical stimulation. We observed medium effect sizes for cognitive and physical functioning in favor of the interactive video gaming condition, but these effects were not statistically significant in this small sample. Conclusion Interactive video gaming is feasible for older adults with MCI and medium effects sizes in favor of the Wii group warrant a larger efficacy trial. PMID:24452845

Recombinant human bone morphogenetic protein-12 (rhBMP-12) has been shown to induce tendon and ligament formation in rats and to improve tendon healing; however, the safety and feasibility of implanting rhBMP-12/absorbable collagen sponge (ACS) in humans are not known. To investigate the safety and feasibility of rhBMP-12 on an ACS as an adjuvant therapy in open rotator cuff repair. Randomized controlled trial; Level of evidence, 2. This study consisted of 20 patients with full-thickness rotator cuff tears. Patients were randomized either to standard of care (SOC) treatment (open rotator cuff repair) or to receive 0.015 mg/mL rhBMP-12/ACS and SOC treatment during their open rotator cuff repair (rhBMP-12/ACS group) at a rate of 1/4 SOC/rhBMP-12/ACS. The feasibility of implanting the product and the safety of the product were evaluated during the 1-year follow-up period. The evaluation involved up to 10 postoperative visits, which included physical examinations, radiographs, computed tomography (CT) scans, magnetic resonance imaging (MRI) scans with an emphasis on heterotopic ossification (HO), pharmacokinetics, immunogenicity, laboratory evaluations, and local and systemic adverse events at specified time points. Small amounts of HO were seen on follow-up CT scans in 10 of 16 patients in the rhBMP-12/ACS group and in 2 of 3 patients in the SOC group. HO did not increase at 26 weeks and was not associated with any adverse events or unsatisfactory clinical outcomes. Pharmacokinetics demonstrated that circulating levels of rhBMP-12 were not detectable after administration. Five of 16 patients showed a postoperative immunogenic response but did not show any correlating adverse events. Complete healing of the rotator cuff was observed in 14 of 16 patients; 2 of 16 imaging results could not be analyzed because of artifacts in the rhBMP-12 group on MRI scans. In the SOC group, 1 of 4 patients showed a retear at 12 weeks after surgery. The use of rhBMP-12/ACS has been shown to be feasible and safe in a concentration of 0.015 mg/mL when used in open rotator cuff repair. Higher dose concentrations of rhBMP-12 should be evaluated in the future to evaluate their safety and potential to increase rotator cuff healing after open surgical repair. © 2015 The Author(s).

The aim of this pilot study was to investigate feasibility and preliminary efficacy of an intensive, manual-based behavioral feeding intervention for children with chronic food refusal and dependence on enteral feeding or oral nutritional formula supplementation. Twenty children ages 13 to 72 months (12 boys and 8 girls) meeting criteria for avoidant/restrictive food intake disorder were randomly assigned to receive treatment for 5 consecutive days in a day treatment program (n = 10) or waitlist (n = 10). A team of trained therapists implemented treatment under the guidance of a multidisciplinary team. Parent training was delivered to support generalization of treatment gains. We tracked parental attrition and attendance, as well as therapist fidelity. Primary outcome measures were bite acceptance, disruptions, and grams consumed during meals. Caregivers reported high satisfaction and acceptability of the intervention. Three participants (1 intervention; 2 waitlist) dropped out of the study before endpoint. Of the expected 140 treatment meals for the intervention group, 137 (97.8%) were actually attended. The intervention group showed significantly greater improvements (P < 0.05) on all primary outcome measures (d = 1.03-2.11) compared with waitlist (d = -1.13-0.24). A 1-month follow-up suggested stability in treatment gains. Results from this pilot study corroborate evidence from single-subject and nonrandomized studies on the positive effects of behavioral intervention. Findings support the feasibility and preliminary efficacy of this manual-based approach to intervention. These results warrant a large-scale randomized trial to test the safety and efficacy of this intervention.

Caring for a person with dementia can be physically and emotionally demanding, with many long-term care facility staff experiencing increased levels of stress and burnout. Massage has been shown to be one way in which nurses' stress can be reduced. However, no research has been conducted to explore its effectiveness for care staff working with older people with dementia in long-term care facilities. This was a pilot, parallel group, randomized controlled trial aimed at exploring feasibility for a larger randomized controlled trial. Nineteen staff, providing direct care to residents with dementia and regularly working ≥ two day-shifts a week, from one long-term care facility in Queensland (Australia), were randomized into either a foot massage intervention (n=9) or a silent resting control (n=10). Each respective session lasted for 10-min, and participants could receive up to three sessions a week, during their allocated shift, over four-weeks. At pre- and post-intervention, participants were assessed on self-report outcome measures that rated mood state and experiences of working with people with dementia. Immediately before and after each intervention/control session, participants had their blood pressure and anxiety measured. An Intention To Treat framework was applied to the analyses. Individual qualitative interviews were also undertaken to explore participants' perceptions of the intervention. The results indicate the feasibility of undertaking such a study in terms of: recruitment; the intervention; timing of intervention; and completion rates. A change in the intervention indicated the importance of a quiet, restful environment when undertaking a relaxation intervention. For the psychological measures, although there were trends indicating improvement in mood there was no significant difference between groups when comparing their pre- and post- scores. There were significant differences between groups for diastolic blood pressure (p= 0.04, partial η2=0.22) and anxiety (p= 0.02, partial η2=0.31), with the foot massage group experiencing greatest decreases immediately after the session. The qualitative interviews suggest the foot massage was well tolerated and although taking staff away from their work resulted in some participants feeling guilty about taking time out, a 10-min foot massage was feasible during a working shift. This pilot trial provides data to support the feasibility of the study in terms of recruitment and consent, the intervention and completion rates. Although the outcome data should be treated with caution, the pilot demonstrated the foot massage intervention showed trends in improved mood, reduced anxiety and lower blood pressure in long-term care staff working with older people with dementia. A larger study is needed to build on these promising, but preliminary, findings. ACTRN: ACTRN12612000659808.

Prior studies suggest hypothermia may be beneficial in acute respiratory distress syndrome, but cooling causes shivering and increases metabolism. The objective of this study was to assess the feasibility of performing a randomized clinical trial of hypothermia in patients with acute respiratory distress syndrome receiving treatment with neuromuscular blockade because they cannot shiver. Retrospective study and pilot, prospective, open-label, feasibility study. Medical ICU. Retrospective review of 58 patients with acute respiratory distress syndrome based on Berlin criteria and PaO2/FIO2 less than 150 who received neuromuscular blockade. Prospective hypothermia treatment in eight acute respiratory distress syndrome patients with PaO2/FIO2 less than 150 receiving neuromuscular blockade. Cooling to 34-36°C for 48 hours. Core temperature, hemodynamics, serum glucose and electrolytes, and P/F were sequentially measured, and medians (interquartile ranges) presented, 28-day ventilator-free days, and hospital mortality were calculated in historical controls and eight cooled patients. Average patient core temperature was 36.7°C (36-37.3°C), and fever occurred during neuromuscular blockade in 30 of 58 retrospective patients. In the prospectively cooled patients, core temperature reached target range less than or equal to 4 hours of initiating cooling, remained less than 36°C for 92% of the 48 hours cooling period without adverse events, and was lower than the controls (34.35°C [34-34.8°C]; p < 0.0001). Compared with historical controls, the cooled patients tended to have lower hospital mortality (75% vs 53.4%; p = 0.26), more ventilator-free days (9 [0-21.5] vs 0 [0-12]; p = 0.16), and higher day 3 P/F (255 [160-270] vs 171 [120-214]; p = 0.024). Neuromuscular blockade alone does not cause hypothermia but allowed acute respiratory distress syndrome patients to be effectively cooled. Results support conducting a randomized clinical trial of hypothermia in acute respiratory distress syndrome and the feasibility of studying acute respiratory distress syndrome patients receiving neuromuscular blockade.

Minimal-risk randomized trials that can be embedded in practice could facilitate learning health-care systems. A cluster-randomized design was proposed to compare treatment strategies by assigning clusters (eg, providers) to "favor" a particular drug, with providers retaining autonomy for specific patients. Patient informed consent might be waived, broadening inclusion. However, it is not known if providers will adhere to the assignment or whether institutional review boards will waive consent. We evaluated the feasibility of this trial design. Agreeable providers were randomized to "favor" either hydrochlorothiazide or chlorthalidone when starting patients on thiazide-type therapy for hypertension. The assignment applied when the provider had already decided to start a thiazide, and providers could deviate from the strategy as needed. Prescriptions were aggregated to produce a provider strategy-adherence rate. All four institutional review boards waived documentation of patient consent. Providers (n=18) followed their assigned strategy for most of their new thiazide prescriptions (n=138 patients). In the "favor hydrochlorothiazide" group, there was 99% adherence to that strategy. In the "favor chlorthalidone" group, chlorthalidone comprised 77% of new thiazide starts, up from 1% in the pre-study period. When the assigned strategy was followed, dosing in the recommended range was 48% for hydrochlorothiazide (25-50 mg/day) and 100% for chlorthalidone (12.5-25.0 mg/day). Providers were motivated to participate by a desire to contribute to a comparative effectiveness study. A study promotional mug, provider information letter, and interactions with the site investigator were identified as most helpful in reminding providers of their study drug strategy. Providers prescribed according to an assigned drug-choice strategy most of the time for the purpose of a comparative effectiveness study. This simple design could facilitate research participation and behavior change in non-research clinicians. Waiver of patient consent can broaden the representation of patients, providers, and settings.

In a pilot randomized controlled trial, examine the feasibility and preliminary efficacy of an 8-week, mindfulness training program (Mindfulness Based Stress Reduction) in a sample of men on active surveillance on important psychological outcomes including prostate cancer anxiety, uncertainty intolerance and posttraumatic growth. Men were randomized to either mindfulness (n = 24) or an attention control arm (n = 19) and completed self-reported measures of prostate cancer anxiety, uncertainty intolerance, global quality of life, mindfulness and posttraumatic growth at baseline, 8 weeks, 6 months and 12 months. Participants in the mindfulness arm demonstrated significant decreases in prostate cancer anxiety and uncertainty intolerance, and significant increases in mindfulness, global mental health and posttraumatic growth. Participants in the control condition also demonstrated significant increases in mindfulness over time. Longitudinal increases in posttraumatic growth were significantly larger in the mindfulness arm than they were in the control arm. While mindfulness training was found to be generally feasible and acceptable among participants who enrolled in the 8-week intervention as determined by completion rates and open-ended survey responses, the response rate between initial enrollment and the total number of men approached was lower than desired (47%). While larger sample sizes are necessary to examine the efficacy of mindfulness training on important psychological outcomes, in this pilot study posttraumatic growth was shown to significantly increase over time for men in the treatment group. Mindfulness training has the potential to help men cope more effectively with some of the stressors and uncertainties associated with active surveillance. Copyright © 2016 John Wiley & Sons, Ltd.

To determine if delivering electronic messages from nurses during the first six months postpartum is feasible, acceptable and effective in improving mood and decreasing parenting stress. Competing demands during the postpartum hospitalization make focused time for nurses to provide education and support difficult. Unmet needs following discharge may increase the incidence of postpartum depression. Untreated depression negatively affects families, especially for vulnerable women with limited access to health care. This is a longitudinal cohort study in three phases. Feasibility and acceptability were assessed during Phases 1 & 2. Phase 3 is a randomized controlled trial (RCT) with three conditions. This protocol was approved by the Institutional Review Board of the maternity hospital on 12 May 2015 and reviewed annually. Women are enrolled during the maternity hospitalization, after which randomization occurs. The control group receives usual care. Intervention I participants receive a standardized electronic message four times/week for six months postpartum. Intervention II participants receive the messages and the option to request a call from a nurse. Electronic surveys at 3 weeks, 3 months and 6 months postpartum measure depressive symptoms using the Edinburgh Postnatal Depression Scale and parenting stress using the Parenting Stress Index-Short form. Patient satisfaction, nursing time and expertise required are also measured. Phase 1 and 2 have demonstrated the intervention is feasible and acceptable to women. Phase 3 enrollment is completed, and the last follow-up surveys were emailed to participants in February 2018. Results will help inform efforts to continue nursing care after hospital discharge.

Despite growing interest in the importance of, and challenges associated with the involvement of patient and population (IPP) in the process of developing and adapting clinical practice guidelines (CPGs), there is a lack of knowledge about the best method to use. This is especially problematic in the field of rehabilitation, where individuals with disabilities might face many barriers to their involvement in the guideline development and adaptation process. The goal of this pilot trial is to document the acceptability, feasibility and effectiveness of two methods of involving patients with a disability (traumatic brain injury) in CPG development. A single-blind, randomized, crossover pragmatic trial will be performed with 20 patients with traumatic brain injury (TBI). They will be randomized into two groups, and each will try two alternative methods of producing recommendations; a discussion group (control intervention) and a Wiki, a webpage that can be modified by those who have access to it (experimental intervention). The participants will rate the acceptability of the two methods, and feasibility will be assessed using indicators such as the number of participants who accessed and completed the two methods, and the number of support interventions required. Twenty experts, blinded to the method of producing the recommendations, will independently rate the recommendations produced by the participants for clarity, accuracy, appropriateness and usefulness. Our trial will allow for the use of optimal IPP methods in a larger project of adapting guidelines for the rehabilitation of individuals with TBI. Ultimately the results will inform the science of CPG development and contribute to the growing knowledge about IPP in rehabilitation settings. Clinical trial KT Canada 87776.

Meeting the complex needs of patients with chronic common mental health disorders (CMHDs) may be the greatest challenge facing organized medical practice. On the basis of a well-established and proven theoretical foundation for controlled respiration as a behavioral intervention for CMHDs, as well as preliminary evidence that gamification can improve health outcomes through increasing patient engagement, this randomized controlled pilot study evaluated the feasibility and clinical efficacy of a mobile health game called "Flowy" ( www.flowygame.com ) that digitally delivered breathing retraining exercises for anxiety, panic, and hyperventilation symptom management. We designed an unblinded, Web-based, parallel-group randomized controlled trial focusing on feasibility, clinical efficacy, and design proof of concept. In the intervention condition (n = 31), participants received free access to "Flowy" for 4 weeks. In the control condition (n = 32), participants were placed on a waitlist for 4 weeks before being offered free access to "Flowy." Online measurements using psychological self-report questionnaires were made at 2 and 4 weeks post-baseline. At trial conclusion, participants found "Flowy" acceptable as an anxiety management intervention. "Flowy" engaged participants sufficiently to endorse proactive gameplay. Intent-to-treat analysis revealed a reduction in anxiety, panic, and self-report hyperventilation scores in both trial arms, with the intervention arm experiencing greater quality of life. Participants perceived "Flowy" as a fun and useful intervention, proactively used "Flowy" as part of their care, and would recommend "Flowy" to family and friends. Our results suggest that a digital delivery of breathing retraining exercises through a mobile health game can manage anxiety, panic, and hyperventilation symptoms associated with CMHDs.

This pilot study aimed at assessing the feasibility and efficacy of a Mat Pilates program in people with mild-to-moderate Parkinson's disease (PD). The participants carried out a Mat Pilates program twice a week for 12 weeks. The Senior Fitness Test battery and the 39-item PD Questionnaire were used to assess the effects of the program on the participants' fitness level and quality of life. A total of 16 patients with mild-to-moderate PD volunteered for and finished the study. The Mat Pilates program proved to be feasible. Adherence to the program was excellent, and no adverse effects were observed. The program had a positive effect on the participants' fitness levels, except for shoulder range of motion and dynamic balance, and on their quality of life. Assessments at follow-up indicated a regression in the improvements obtained by the end of the intervention, even though the sample still showed higher levels of fitness and quality of life than those tested at baseline. Mat Pilates is feasible and may be a beneficial rehabilitation strategy to improve fitness and quality of life in people with mild-to-moderate PD. Future randomized controlled trials might determine the extent of such benefits.

Wireless monitoring of pulmonary artery (PA) pressures with the CardioMEMS HF™ system is indicated in patients with New York Heart Association (NYHA) class III heart failure (HF). Randomized and observational trials have shown a reduction in HF-related hospitalizations and improved quality of life in patients using this device in the United States. MEMS-HF is a prospective, non-randomized, open-label, multicenter study to characterize safety and feasibility of using remote PA pressure monitoring in a real-world setting in Germany, The Netherlands and Ireland. After informed consent, adult patients with NYHA class III HF and a recent HF-related hospitalization are evaluated for suitability for permanent implantation of a CardioMEMS™ sensor. Participation in MEMS-HF is open to qualifying subjects regardless of left ventricular ejection fraction (LVEF). Patients with reduced ejection fraction must be on stable guideline-directed pharmacotherapy as tolerated. The study will enroll 230 patients in approximately 35 centers. Expected duration is 36 months (24-month enrolment plus ≥ 12-month follow-up). Primary endpoints are freedom from device/system-related complications and freedom from pressure sensor failure at 12-month post-implant. Secondary endpoints include the annualized rate of HF-related hospitalization at 12 months versus the rate over the 12 months preceding implant, and health-related quality of life. Endpoints will be evaluated using data obtained after each subject's 12-month visit. The MEMS-HF study will provide robust evidence on the clinical safety and feasibility of implementing haemodynamic monitoring as a novel disease management tool in routine out-patient care in selected European healthcare systems.

Objectives To assess the feasibility of conducting trials of static magnetic field (SMF) therapy for carpal tunnel syndrome (CTS), to collect preliminary data on the effectiveness of two SMF dosages and to explore the influence of a SMF on median nerve conduction. Design Randomized, double blind, sham controlled trial with 6-week intervention and 12-week follow-up. Setting University hospital outpatient clinics Participants Women and men (N=60), ages 21–65, with electrophysiologically-confirmed CTS diagnosis, recruited from the general population. Interventions Participants wore nightly either neodymium magnets that delivered either 15 or 45mTesla (mT) to the contents of the carpal canal, or a non-magnetic disk. Main Outcome Measures Symptom Severity Scale (SSS) and Function Severity Scale (FSS) of the Boston Carpal Tunnel Questionnaire (BCTQ) and 4 median nerve parameters: sensory distal latency, sensory nerve action potential amplitude, motor distal latency and compound motor action potential amplitude). Results 58 of 60 randomized participants completed the study. There were no significant between-group differences for change in the primary endpoint SSS or for FSS or median nerve conduction parameters. For the SSS and the FSS each group showed a reduction at 6-weeks indicating improvement in symptoms. Conclusions This study demonstrated the feasibility and safety of testing SMF therapy for CTS. There were no between-group differences observed for the BCTQ or median nerve parameters following 6 weeks of SMF therapy. Significant within-group, symptomatic improvements of the same magnitude were experienced by participants in both active and sham magnet groups. Future studies are needed to optimize SMF dosimetry and resolve issues related to the use of sham controls in SMF trials. PMID:20599049

Perinatal women with identified depression in prenatal care settings have low rates of engagement and adherence with depression-specific psychotherapy. We report the feasibility and symptom outcomes of Cognitive Behavioral Therapy (CBT) modified (mCBT) to address the needs of perinatal, low-income women with Major Depressive Disorder (MDD). Pregnant women (n = 1421) were screened for depressive symptoms in obstetrics clinics in conjunction with prenatal care visits. A total of 59 women met diagnostic criteria for MDD; 55 women were randomly assigned to mCBT or Treatment as Usual (TAU). The mCBT intervention included an initial engagement session, outreach, specific perinatal content and interpersonal components. Measures were gathered at pre-treatment, 16 week post-randomization, and 3-month follow-up. Most participants attended at least one CBT session and met study criteria for treatment adherence. Active research staff outreach promoted engagement and retention in the trial. Treatment satisfaction was rated as very good. In both observed and multiple imputation results, women who received mCBT demonstrated greater improvement in depressed mood than those in TAU at 16-week post-randomization and 3-month follow-up, Cohen's d = -0.71 (95% CI -4.93, -5.70). Modified CBT offers promise as a feasible and acceptable treatment for perinatal women with low-incomes in prenatal care settings. Targeted delivery and content modifications are needed to engage populations tailored to setting and psychosocial challenges specific to the perinatal period. © 2013 Wiley Periodicals, Inc.

Aims Deprescribing is a suggested intervention to reverse the potential iatrogenic harms of inappropriate polypharmacy. The review aimed to determine whether or not deprescribing is a safe, effective and feasible intervention to modify mortality and health outcomes in older adults. Methods Specified databases were searched from inception to February 2015. Two researchers independently screened all retrieved articles for inclusion, assessed study quality and extracted data. Data were pooled using RevMan v5.3. Eligible studies included those where older adults had at least one medication deprescribed. The primary outcome was mortality. Secondary outcomes were adverse drug withdrawal events, psychological and physical health outcomes, quality of life, and medication usage (e.g. successful deprescribing, number of medications prescribed, potentially inappropriate medication use). Results A total of 132 papers met the inclusion criteria, which included 34 143 participants aged 73.8 ± 5.4 years. In nonrandomized studies, deprescribing polypharmacy was shown to significantly decrease mortality (OR 0.32, 95% CI: 0.17–0.60). However, this was not statistically significant in the randomized studies (OR 0.82, 95% CI 0.61–1.11). Subgroup analysis revealed patient‐specific interventions to deprescribe demonstrated a significant reduction in mortality (OR 0.62, 95% CI 0.43–0.88). However, generalized educational programmes did not change mortality (OR 1.21, 95% CI 0.86–1.69). Conclusions Although nonrandomized data suggested that deprescribing reduces mortality, deprescribing was not shown to alter mortality in randomized studies. Mortality was significantly reduced when applying patient‐specific interventions to deprescribe in randomized studies. PMID:27077231

Developing, testing and implementing evidence-based prevention interventions are important in decreasing substance use and sexual risk behavior among adolescents. This process requires research expertise, infrastructure, resources and decades of research testing, which might not always be feasible for low resource countries. Adapting and testing interventions proven to be efficacious in similar cultures might circumvent the time and costs of implementing evidence-based interventions in new settings. This paper describes the two-phase study, including training and development of the research infrastructure in the Ecuadorian university necessary to implement a randomized controlled trial. Familias Unidas is a multilevel parent-centered intervention designed in the U.S. to prevent drug use and sexual risk behaviors in Hispanic adolescents. The current study consisted of Phase 1 feasibility study (n=38) which adapted the intervention and study procedures within a single-site school setting in an area with a high prevalence of drug use and unprotected sexual behavior among adolescents in Ecuador, and Phase 2 randomized controlled trial of the adapted intervention in two public high schools with a target population of families with adolescents from 12 to 14 years old. The trial is currently in Phase 2. Study recruitment was completed with 239 parent-youth dyads enrolling. The intervention phase and the first follow-up assessment have been completed. The second and third follow-up assessments will be completed in 2016. This project has the potential of benefitting a large population of families in areas of Ecuador that are disproportionally affected by drug trafficking and its consequences.

A randomized controlled trial was carried out for 1 y in three tertiary and teaching hospitals, in Addis Ababa (Ethiopia), Yogyakarta (Indonesia) and Merida (Mexico), to study the effectiveness, feasibility, acceptability and cost of kangaroo mother care (KMC) when compared to conventional methods of care (CMC). About 29% of 649 low birthweight infants (LBWI; 1000-1999 g) died before eligibility. Of the survivors, 38% were excluded for various reasons, 149 were randomly assigned to KMC (almost exclusive skin-to-skin care after stabilization), and 136 to CMC (warm room or incubator care). There were three deaths in each group and no difference in the incidence of severe disease. Hypothermia was significantly less common in KMC infants in Merida (13.5 vs 31.5 episodes/100 infants/d) and overall (10.8 vs 14.6). Exclusive breastfeeding at discharge was more common in KMC infants in Merida (80% vs 16%) and overall (88% vs 70%). KMC infants had a higher mean daily weight gain (21.3 g vs 17.7 g) and were discharged earlier (13.4 vs 16.3 d after enrolment). KMC was considered feasible and presented advantages over CMC in terms of maintenance of equipment. Mothers expressed a clear preference for KMC and health workers found it safe and convenient. KMC was cheaper than CMC in terms of salaries (US$ 11,788 vs US$ 29,888) and other running costs (US$ 7501 vs US$ 9876). This study confirms that hospital KMC for stabilized LBWI 1000-1999 g is at least as effective and safe as CMC, and shows that it is feasible in different settings, acceptable to mothers of different cultures, and less expensive. Where exclusive breastfeeding is uncommon among LBWI, KMC may bring about an increase in its prevalence and duration, with consequent benefits for health and growth. For hospitals in low-income countries KMC may represent an appropriate use of scarce resources.

Adolescents with anorexia nervosa who have obsessive-compulsive (OC) features respond poorly to family-based treatment (FBT). This study evaluated the feasibility of combining FBT with either cognitive remediation therapy (CRT) or art therapy (AT) to improve treatment response in this at-risk group. Thirty adolescents with anorexia nervosa and OC features were randomized to 15 sessions of FBT + CRT or AT. Recruitment rate was 1 per month, and treatment attrition was 16.6% with no differences between groups. Suitability, expectancy and therapeutic relationships were acceptable for both combinations. Correlations between changes in OC traits and changes in cognitive inefficiencies were found for both combinations. Moderate changes in cognitive inefficiencies were found in both groups but were larger in the FBT + AT combination. This study suggests that an RCT for poor responders to FBT because of OC traits combining FBT with either CRT or AT is feasible to conduct.

Type two diabetes is a complex and demanding chronic disease and its impact in a state (Kerala) which leads India in terms of the number of people with Diabetes is profound. Though the male to female ratio among the people with diabetes is roughly equal, women are uniquely and more severely affected. Management of type two Diabetes requires considerable dexterity on the part of the patient to manage drugs, diet and exercise. Therefore, in a low middle-income country like India it is necessary to look at low cost interventions that can empower the patient and build on available resources to help manage diabetes. Hence, we studied the feasibility and effect of two low cost interventions; yoga and peer support on glycaemic and other outcomes among women with type two diabetes. An open label parallel three armed randomized control trial was conducted among 124 recruited women with Diabetes for three months. Block randomization with a block length of six was carried out with each group having at least 41 women. In the Yoga arm, sessions by an instructor, consisting of a group of postures coordinated with breathing were conducted for an hour, two days a week. In the peer support arm each peer mentor after training visited 13-14 women with diabetes every week followed by a phone call. The meeting was about applying disease management or prevention plans in daily life. There was a trend in decline of fasting plasma glucose in the peer and yoga group and of glycosylated haemoglobin (HbA1c) in the yoga group only, though not significant. A significant decrease was observed in diastolic blood pressure and hip circumference in the yoga group. The process indicated that most (80%) of the women in the yoga group attended classes regularly and 90% of the women in the peer group reported that peer mentoring was useful. The effect of yoga and peer support on glycaemic outcomes was incremental. Longer term studies are necessary to ascertain the benefits shown by this feasibility study.

Although good progress has been achieved in expanding immunization of children in China, disparities exist across different provinces. Information gaps both from the service supply and demand sides hinder timely vaccination of children in rural areas. The rapid development of mobile health technology (mHealth) provides unprecedented opportunities for improving health services and reaching underserved populations. However, there is a lack of literature that rigorously evaluates the impact of mHealth interventions on immunization coverage as well as the usability and feasibility of smart phone applications (apps). This study aims to assess the effectiveness of a smart phone-based app (Expanded Program on Immunization app, or EPI app) on improving the coverage of children's immunization. This cluster randomized trial will take place in Xuanhan County, Sichuan Province, China. Functionalities of the app include the following: to make appointments automatically, record and update children's immunization information, generate a list of children who missed their vaccination appointments, and send health education information to village doctors. After pairing, 36 villages will be randomly allocated to the intervention arm (n=18) and control arm (n=18). The village doctors in the intervention arm will use the app while the village doctors in the control arm will record and manage immunization in the usual way in their catchment areas. A household survey will be used at baseline and at endline (8 months of implementation). The primary outcome is full-dose coverage and the secondary outcome is immunization coverage of the five vaccines that are included in the national Expanded Program on Immunization program as well as Hib vaccine, Rotavirus vaccine and Pneumococcal conjugate vaccine. Multidimensional evaluation of the app will also be conducted to assess usability and feasibility. This study is the first to evaluate the effectiveness of a smart phone app for child immunization in rural China. This study will contribute to the knowledge about the usability and feasibility of a smart phone app for managing immunization in rural China and to similar populations in different settings.

Current pulse amplitude used in clinical ECT may be higher than needed. Reducing pulse amplitude may improve focality of the electric field and thus cognitive adverse effects. Here we examine the feasibility, safety, and whether Low Pulse Amplitude Seizure Therapy (LAP-ST, 0.5-0.6A) minimizes cognitive adverse effects while retaining efficacy. Patients with treatment-resistant primary mood (depressive episodes) or psychotic disorders who were clinically indicated to undergo ECT were offered to be enrolled in an open-label study. The study consisted of a full acute course of LAP-ST under standard anesthesia and muscle relaxation. The primary outcome was feasibility of seizure induction. Clinical outcome measures were: time to reorientation (TRO), Mini Mental State Examination, Montgomery Aberg Depression Scale, and Brief Psychiatric Rating Scale, and Clinical Global Impression Scale. Twenty-two patients consented for enrollment in the study. LAP-ST was feasible, and all patients had seizures in the first session. Participants had a quick orientation with median TRO of 4.5min. Treatment was efficacious for both depressive and psychotic symptoms. Relatively small sample size, non-blinded, and no randomization was performed in this initial proof of concept study. This first human preliminary data of a full course of focal LAP-ST demonstrates that seizure induction is feasible. These results, although preliminary, suggest that the LAP-ST compared to the standard ECT techniques may result in less cognitive side effects, but comparable efficacy. Larger studies are needed to replicate these findings. Copyright © 2017 Elsevier B.V. All rights reserved.
Feasibility and Effectiveness of Using Wearable Activity Trackers in Youth: A Systematic Review
McNarry, Melitta A; Mackintosh, Kelly A
2016-01-01
Background The proliferation and popularity of wearable activity trackers (eg, Fitbit, Jawbone, Misfit) may present an opportunity to integrate such technology into physical activity interventions. While several systematic reviews have reported intervention effects of using wearable activity trackers on adults’ physical activity levels, none to date have focused specifically on children and adolescents. Objective The aim of this review was to examine the effectiveness of wearable activity trackers as a tool for increasing children’s and adolescents’ physical activity levels. We also examined the feasibility of using such technology in younger populations (age range 5-19 years). Methods We conducted a systematic search of 5 electronic databases, reference lists, and personal archives to identify articles published up until August 2016 that met the inclusion criteria. Articles were included if they (1) specifically examined the use of a wearable device within an intervention or a feasibility study; (2) included participants aged 5-19 years old; (3) had a measure of physical activity as an outcome variable for intervention studies; (4) reported process data concerning the feasibility of the device in feasibility studies; and (5) were published in English. Data were analyzed in August 2016. Results In total, we identified and analyzed 5 studies (3 intervention, 2 feasibility). Intervention delivery ranged from 19 days to 3 months, with only 1 study using a randomized controlled trial design. Wearable activity trackers were typically combined with other intervention approaches such as goal setting and researcher feedback. While intervention effects were generally positive, the reported differences were largely nonsignificant. The feasibility studies indicated that monitor comfort and design and feedback features were important factors to children and adolescents. Conclusions There is a paucity of research concerning the effectiveness and feasibility of wearable activity trackers as a tool for increasing children’s and adolescents’ physical activity levels. While there are some preliminary data to suggest these devices may have the potential to increase activity levels through self-monitoring and goal setting in the short term, more research is needed to establish longer-term effects on behavior.

Major depressive disorder (MDD) is a common, debilitating chronic condition in the United States and worldwide. Particularly in women, depressive symptoms are often accompanied by high levels of stress and ruminations, or repetitive self-critical negative thinking. There is a research and clinical imperative to evaluate complementary therapies that are acceptable and feasible for women with depression and that target specific aspects of depression in women, such as ruminations. To begin to address this need, we conducted a randomized, controlled, mixed-methods community-based study comparing an 8-week yoga intervention with an attention-control activity in 27 women with MDD. After controlling for baseline stress, there was a decrease in depression over time in both the yoga group and the attention-control group, with the yoga group having a unique trend in decreased ruminations. Participants in the yoga group reported experiencing increased connectedness and gaining a coping strategy through yoga. The findings provide support for future large scale research to explore the effects of yoga for depressed women and the unique role of yoga in decreasing rumination. PMID:23706890

Targeting sedentary time post exacerbation may be more relevant than targeting structured exercise for individuals with chronic obstructive pulmonary disease. Focusing interventions on sitting less and moving more after an exacerbation may act as a stepping stone to increase uptake to pulmonary rehabilitation. The aim of this paper was to conduct a randomized trial examining trial feasibility and the acceptability of an education and self-monitoring intervention using wearable technology to reduce sedentary behavior for individuals with chronic obstructive pulmonary disease admitted to hospital for an acute exacerbation. Participants were recruited and randomized in hospital into 3 groups, with the intervention lasting 2 weeks post discharge. The Education group received verbal and written information about reducing their time in sedentary behavior, sitting face-to-face with a study researcher. The Education+Feedback group received the same education component along with real-time feedback on their sitting time, stand-ups, and steps at home through a waist-worn inclinometer linked to an app. Patients were shown how to use the technology by the same study researcher. The inclinometer also provided vibration prompts to encourage movement at patient-defined intervals of time. Patients and health care professionals involved in chronic obstructive pulmonary disease exacerbation care were interviewed to investigate trial feasibility and acceptability of trial design and methods. Main quantitative outcomes of trial feasibility were eligibility, uptake, and retention, and for acceptability, were behavioral responses to the vibration prompts. In total, 111 patients were approached with 33 patients recruited (11 Control, 10 Education, and 12 Education+Feedback). Retention at 2-week follow-up was 52% (17/33; n=6 for Control, n=3 for Education, and n=8 for Education+Feedback). No study-related adverse events occurred. Collectively, patients responded to 106 out of 325 vibration prompts from the waist-worn inclinometer (32.62%). Within 5 min of the prompt, 41% of responses occurred, with patients standing for a mean 1.4 (SD 0.8) min and walking for 0.4 (SD 0.3) min (21, SD 11, steps). Interviews indicated that being unwell and overwhelmed after an exacerbation was the main reason for not engaging with the intervention. Health care staff considered reducing sedentary behavior potentially attractive for patients but suggested starting the intervention as an inpatient. Although the data support that it was feasible to conduct the trial, modifications are needed to improve participant retention. The intervention was acceptable to most patients and health care professionals.

Increasing physical activity (PA) brings many health benefits, but engaging people in higher levels of PA after their 60s is not straightforward. The Functional Fitness MOT (FFMOT) is a new approach which aims to raise awareness about the importance of components of fitness (strength, balance, flexibility), highlight benefits of PA, engages older people in health behavior change discussions, and directs them to local activity resources. This battery of tests combined with a brief motivational interview has not been tested in terms of feasibility or effectiveness. To assess whether the FFMOT, provided in a health care setting, is appealing to older patients of a community physiotherapy service and to understand the views and perceptions of the older people undergoing the FFMOT regarding the intervention, as well as the views of the physiotherapy staff delivering the intervention. Secondary aims are to assess the feasibility of carrying out a phase 2 pilot randomized controlled trial of the FFMOT, in the context of a community physiotherapy service, by establishing whether enough patients can be recruited and retained in the study, and enough outcome data can be generated. A mixed-methods feasibility study will be conducted in two physiotherapy outpatient clinics in the United Kingdom. A total of 30 physically inactive, medically stable older adults over the age of 60 will be provided with an individual FFMOT, comprising a set of six standardized, validated, age-appropriate tests aimed at raising awareness of the different components of fitness. The results of these tests will be used to provide the participants with feedback on performance in comparison to sex and age-referenced norms. This will be followed by tailored advice on how to become more active and improve fitness, including advice on local opportunities to be more active. Subsequently, participants will be invited to attend a focus group to discuss barriers and motivators to being more active, health behavior change, and the scope for individuals to improve their PA levels. To inform the design of a future trial, descriptive (eg, recruitment and retention rates), quantitative (Community Healthy Activities Model Program for Seniors; CHAMPS physical activity questionnaire), and qualitative data (focus group discussions, semi-structured staff interviews) will be collected. Recruitment and enrolment for the trial started in September 2015. Follow-up will be completed in June 2016. Results are expected to be available at the end of 2016. Allied health professionals play a key role in encouraging older adults to increase their PA, but with little evidence on how best to do this within their clinical practice. The purpose of this feasibility study is to examine the introduction of a new service: The FFMOT. The views and perceptions of the older people undergoing the FFMOT and relating to its delivery in clinical practice will be explored. Data, which will inform the feasibility of a randomized controlled trial of effectiveness of the FFMOT in promoting improved PA, will be reported.

To evaluate the feasibility and functional urinary and digestive results of nerve sparing techniques in endometriosis surgery. A research on the medline/pubmed database using specific keywords (nerve sparing, endometriosis, pelvic nerves) identified 7 publications among about 50 whose purpose was to describe the feasibility, the techniques and the functional results of nerve preservation in this indication. Among them there are: 2 uncontrolled retrospective studies, 3 prospective non-randomized studies, a meta-analysis and a review of the literature. Nerve preservation requires a perfect knowledge of the anatomy of the pelvic autonomic system. The laparoscopic approach is preferred by the different authors due to its anatomical advantage. The feasibility of this technique seems to be demonstrated despite certain limitations in the different studies and depending of the retroperitoneal extension of the lesions. When feasible, it is likely to significantly improve postoperative urinary function (urinary retention) compared to a conventional technique. It is observed no difference regarding digestive function. Nerve sparing in this indication is a technique the feasibility of which has been demonstrated and is subject to the topography and extent of the disease. In the absence of invasion or entrapment of pelvic autonomic nerves by endometriosis, this technique improves postoperative voiding function (NP3). During pelvic surgery for endometriosis, it is recommended to identify and preserve autonomic pelvic nerves whenever possible (GradeC). Copyright © 2018. Published by Elsevier Masson SAS.

The primary objective was to determine the feasibility of a large RCT assessing the effectiveness of an accelerated oxytocin titration (AOT) protocol compared with a standard gradual oxytocin titration (GOT) in reducing the risk of CS in nulliparous women diagnosed with dystocia in the first stage of labour. The secondary objective was to obtain preliminary data on the safety and efficacy of the foregoing AOT protocol. This was a multicentre, double-masked, parallel-group pilot RCT. This study was conducted in three Canadian birthing centres. A total of 79 term nulliparous women carrying a singleton pregnancy in spontaneous labour, with a diagnosis of labour dystocia, were randomized to receive either GOT (initial dose 2 mU/min with increments of 2 mU/min) or AOT (initial dose 4 mU/min with increments of 4 mU/min), in a 1:1 ratio. An intention-to-treat analysis was applied. A total of 252 women were screened and approached, 137 (54.4%) consented, and 79 (31.3%) were randomized. Overall protocol adherence was 76 of 79 (96.2%). Of the women randomized, 10 (25.6%) allocated to GOT had a CS compared with six (15.0%) allocated to AOT (Fisher exact test P = 0.27). This pilot study demonstrated that a large, multicentre RCT is not only feasible, but also necessary to assess the effectiveness and safety of an AOT protocol for labour augmentation with regard to CS rate and indicators of maternal and perinatal morbidities.

Few studies have examined the effectiveness of community-based self-management interventions in older adults with type 2 diabetes mellitus (T2DM) and multiple chronic conditions (MCC). The objectives of this study were to examine the feasibility of implementation in practice (primary) and the feasibility of study methods and potential effectiveness (secondary) of the Aging, Community and Health-Community Partnership Program, a new 6-month interprofessional, nurse-led program to promote diabetes self-management in older adults (>65 years) with T2DM and MCC. This study used a prospective one-group pre-test/post-test design. Participants were recruited from a specialized diabetes clinic. They received a median of three in-home/clinic visits by certified diabetes educators (CDEs) and attended a median of three group wellness sessions provided by the CDEs in partnership with a community-based seniors' association. The primary outcome was the feasibility of the program (acceptability, fidelity, implementation barriers/facilitators). Secondary outcomes included the feasibility of the study methods (recruitment/retention rates and procedures, eligibility criteria, data collection and analysis methods) and potential effectiveness of the program based on 6-month changes in self-reported outcomes including self-management behavior (diet, exercise, self-monitoring), health status (quality of life, mental health), and costs of service use. Analysis of feasibility outcomes was primarily based on descriptive statistics. The potential effectiveness of the program was explored using different tests, with the results expressed using descriptive statistics and effect estimates (95 % confidence intervals). In total, 45 (88 %) of 51 eligible persons consented to participate. Of these, 37 (82 %) completed the 6-month follow-up. Participants and providers viewed the program as acceptable and feasible. Participants had a higher SF-12 physical component summary score at 6 months compared with baseline (mean score difference 3.0, 95 % CI 0.2-5.8). Median costs for diabetes care increased over 6 months (reflecting inclusion of program costs), while other service costs either decreased or remained unchanged. This study offers preliminary evidence that the program was feasible to deliver and acceptable to participants and providers. Initial results suggest that the program may improve physical functioning. A randomized controlled trial is feasible, with some adaptations to the program and study methods that were identified from this feasibility study. Clinicaltrials.gov identifier: NCT01880476.

The author has identified the following significant results. Yield modelling for crop production estimation derived a means of predicting the within-a-year yield and the year-to-year variability of yield over some fixed or randomly located unit of area. Preliminary studies indicated that the requirements for interpreting LANDSAT data for yield may be sufficiently similar to those of signature extension that it is feasible to investigate the automated estimation of production. The concept of an advanced yield model consisting of both spectral and meteorological components was endorsed. Rationale for using meteorological parameters originated from known between season and near harvest dynamics in crop environmental-condition-yield relationships.
Low-dose aspirin in polycythaemia vera: a pilot study. Gruppo Italiano Studio Policitemia (GISP).
1997-05-01
In this pilot study, aimed at exploring the feasibility of a large-scale trial of low-dose aspirin in polycythaemia vera (PV), 112 PV patients (42 females, 70 males. aged 17-80 years) were selected for not having a clear indication for, or contraindication to, aspirin treatment and randomized to receive oral aspirin (40 mg/d) or placebo. Follow-up duration was 16 +/- 6 months. Measurements of thromboxane A2 production during whole blood clotting demonstrated complete inhibition of platelet cyclooxygenase activity in patients receiving aspirin. Aspirin administration was not associated with any bleeding complication. Within the limitations of the small sample size, this study indicates that a biochemically effective regimen of antiplatelet therapy is well tolerated in patients with polycythaemia vera and that a large-scale placebo-controlled trial is feasible.

Cognitive impairments are common in homeless youth and negatively impact academic and vocational outcomes. We examined the feasibility and efficacy of cognitive interventions provided to 18- to 22-year-old homeless youth living in urban supportive housing. Ninety-one homeless youth were randomized to receive either targeted cognitive training (cognitive remediation) or general cognitive activation (computer skills training). Cognitive and psychological outcomes were assessed at baseline, after 13 and 26 sessions, and 1 month postintervention. A high dropout rate highlighted the feasibility challenges of treating this population. Intent-to-treat analysis found significant improvements across groups in specific and global measures of cognition and psychological distress, with no significant group differences. Transition-age homeless youth show improvements in cognitive and psychological functioning when engaged in interventions that address their cognitive development. This speaks to the malleability of cognitive skills in this cohort and lays the groundwork for future research to address their cognitive health.

Objectives To examine the feasibility/acceptability of a parent-delivered Active Music Engagement (AME + P) intervention for young children with cancer and their parents. Secondary aim to explore changes in AME + P child emotional distress (facial affect) and parent emotional distress (mood; traumatic stress symptoms) relative to controls. Methods A pilot two-group randomized trial was conducted with parents/children (ages 3–8 years) receiving AME + P (n = 9) or attention control (n = 7). Feasibility of parent delivery was assessed using a delivery checklist and child engagement; acceptability through parent interviews; preliminary outcomes at baseline, postintervention, 30 days postintervention. Results Parent delivery was feasible, as they successfully delivered AME activities, but interviews indicated parent delivery was not acceptable to parents. Emotional distress was lower for AME + P children, but parents derived no benefit. Conclusion Despite child benefit, findings do not support parent delivery of AME + P. PMID:27289068
'Mendelian randomization': an approach for exploring causal relations in epidemiology.
Gupta, V; Walia, G K; Sachdeva, M P
2017-04-01
To assess the current status of Mendelian randomization (MR) approach in effectively influencing the observational epidemiology for examining causal relationships. Narrative review on studies related to principle, strengths, limitations, and achievements of MR approach. Observational epidemiological studies have repeatedly produced several beneficiary associations which were discarded when tested by standard randomized controlled trials (RCTs). The technique which is more feasible, highly similar to RCTs, and has the potential to establish a causal relationship between modifiable exposures and disease outcomes is known as MR. The technique uses genetic variants related to modifiable traits/exposures as instruments for detecting causal and directional associations with outcomes. In the last decade, the approach of MR has methodologically developed and progressed to a stage of high acceptance among the epidemiologists and is gradually expanding the landscape of causal relationships in non-communicable chronic diseases.

It has not been established whether progressive resistance training (PRT) and aerobic training (AT) are feasible and efficient in myasthenia gravis (MG). Fifteen subjects with generalized MG (Myasthenia Gravis Foundation of America (MGFA) clinical classification II-IV) were randomly assigned to 20 training sessions during 8 weeks of either PRT or AT. Feasibility was evaluated based on adherence, drop-out rate, adverse events, and Quantitative Myasthenia Gravis (QMG) score. Twelve subjects (MGFA II, n = 11; MGFA III, n=1) completed the intervention with a mean adherence of 95 % ± 8. One dropout (PRT) could potentially be related to PRT. Both groups reported adverse events, including bulbar symptoms (n = 2) and increased fatigue (n = 3), but no change in QMG score was observed in either group. The PRT group showed increases in maximal strength and functional capacity. Eight weeks of moderate to high intensity AT and PRT were feasible for most patients with mild MG. Maximal strength and functional capacity increased in the PRT group. Muscle Nerve 56: 700-709, 2017. © 2017 Wiley Periodicals, Inc.

To investigate the feasibility of using video-games in a group setting and to compare the effectiveness of video-games as a group intervention to a traditional group intervention for improving physical activity in individuals with chronic stroke. A single-blind randomized controlled trial with evaluations pre and post a 3-month intervention, and at 3-month follow-up. Compliance (session attendance), satisfaction and adverse effects were feasibility measures. Grip strength and gait speed were measures of physical activity. Hip accelerometers quantified steps/day and the Action Research Arm Test assessed the functional ability of the upper extremity. Forty-seven community-dwelling individuals with chronic stroke (29-78 years) were randomly allocated to receive video-game (N=24) or traditional therapy (N=23) in a group setting. There was high treatment compliance for both interventions (video-games-78%, traditional therapy-66%), but satisfaction was rated higher for the video-game (93%) than the traditional therapy (71%) (χ(2)=4.98, P=0.026). Adverse effects were not reported in either group. Significant improvements were demonstrated in both groups for gait speed (F=3.9, P=0.02), grip strength of the weaker (F=6.67, P=0.002) and stronger hands (F=7.5, P=0.001). Daily steps and functional ability of the weaker hand did not increase in either group. Using video-games in a small group setting is feasible, safe and satisfying. Video-games improve indicators of physical activity of individuals with chronic stroke. © The Author(s) 2015.

Objective To determine whether actively using, methamphetamine (meth)-dependent men who have sex with men (MSM) could be enrolled and retained in a pharmacologic intervention trial, and the degree to which participants would adhere to study procedures, including medication adherence. Study design Phase II randomized, double-blind trial of bupropion vs. placebo. Methods Thirty meth-dependent, sexually active MSM were randomized to receive daily bupropion XL 300 mg or placebo for 12 weeks. Participants received weekly substance use counseling, provided weekly urine specimens, and completed monthly audio-computer assisted self-interview (ACASI) behavioral risk assessments. Adherence was measured by medication event monitoring systems (MEMS) caps (the number of distinct MEMS cap openings divided by the number of expected doses) and self-report. Results Ninety percent completed the trial: 89% of monthly ACASIs were completed, 81% of study visits were attended, and 81% of urine samples were collected. Adherence by MEMS cap was 60% and by self-report was 81% and did not differ significantly by treatment assignment. The median number of positive urine samples was 5.5 out of a possible 11 (50%). Participants in both arms reported similar declines in the median number of sex partners (P = 0.52). No serious adverse events occurred and there were no significant differences in adverse events by treatment assignment (P = 0.11). Conclusions It is feasible to enroll and retain actively using, meth-dependent MSM in a pharmacologic intervention. Bupropion was well tolerated. Study participation and retention rates were high, however, study drug medication adherence was only moderate. Findings support a larger trial with improved adherence support to evaluate the efficacy of bupropion and other pharmacologic interventions for meth dependence in this population. PMID:20397286

ADHD affects between 2% and 8% of college students and is associated with broad functional impairment. No prior randomized controlled trials with this population have been published. The present study is a pilot randomized controlled trial evaluating dialectical behavior therapy (DBT) group skills training adapted for college students with ADHD. Thirty-three undergraduates with ADHD between ages 18 and 24 were randomized to receive either DBT group skills training or skills handouts during an 8-week intervention phase. ADHD symptoms, executive functioning (EF), and related outcomes were assessed at baseline, post-treatment, and 3-month follow-up. Participants receiving DBT group skills training showed greater treatment response rates (59-65% vs. 19-25%) and clinical recovery rates (53-59% vs. 6-13%) on ADHD symptoms and EF, and greater improvements in quality of life. DBT group skills training may be efficacious, acceptable, and feasible for treating ADHD among college students. A larger randomized trial is needed for further evaluation. © 2014 SAGE Publications.

Pesticide suicides are considered the single most important means of suicide worldwide. Centralized pesticide storage facilities have the possible advantage of delaying access to pesticides thereby reducing suicides. We undertook this study to examine the feasibility and acceptability of a centralized pesticide storage facility as a preventive intervention strategy in reducing pesticide suicides. A community randomized controlled feasibility study using a mixed methods approach involving a household survey; focus group discussions (FGDs) and surveillance were undertaken. The study was carried out in a district in southern India. Eight villages that engaged in floriculture were identified. Using the lottery method two were randomized to be the intervention sites and two villages constituted the control site. Two centralized storage facilities were constructed with local involvement and lockable storage boxes were constructed. The household survey conducted at baseline and one and a half years later documented information on sociodemographic data, pesticide usage, storage and suicides. At baseline 4446 individuals (1097 households) in the intervention and 3307 individuals (782 households) in the control sites were recruited while at follow up there were 4308 individuals (1063 households) in the intervention and 2673 individuals (632 households) in the control sites. There were differences in baseline characteristics and imbalances in the prevalence of suicides between intervention and control sites as this was a small feasibility study.The results from the FGDs revealed that most participants found the storage facility to be both useful and acceptable. In addition to protecting against wastage, they felt that it had also helped prevent pesticide suicides as the pesticides stored here were not as easily and readily accessible. The primary analyses were done on an Intention to Treat basis. Following the intervention, the differences between sites in changes in combined, completed and attempted suicide rates per 100,000 person-years were 295 (95% CI: 154.7, 434.8; p < 0.001) for pesticide suicide and 339 (95% CI: 165.3, 513.2, p < 0.001) for suicide of all methods. Suicide by pesticides poisoning is a major public health problem and needs innovative interventions to address it. This study, the first of its kind in the world, examined the feasibility of a central storage facility as a means of limiting access to pesticides and, has provided preliminary results on its usefulness. These results need to be interpreted with caution in view of the imbalances between sites. The facility was found to be acceptable, thereby underscoring the need for larger studies for a longer duration. ISRCTN04912407.

[Purpose] This study aims to describe a protocol based on neurocognitive therapeutic exercises and determine its feasibility and usefulness for upper extremity functionality when compared with a conventional protocol. [Subjects and Methods] Eight subacute stroke patients were randomly assigned to a conventional (control group) or neurocognitive (experimental group) treatment protocol. Both lasted 30 minutes, 3 times a week for 10 weeks and assessments were blinded. Outcome measures included: Motor Evaluation Scale for Upper Extremity in Stroke Patients, Motricity Index, Revised Nottingham Sensory Assessment and Kinesthetic and Visual Imagery Questionnaire. Descriptive measures and nonparametric statistical tests were used for analysis. [Results] The results indicate a more favorable clinical progression in the neurocognitive group regarding upper extremity functional capacity with achievement of the minimal detectable change. The functionality results are related with improvements on muscle strength and sensory discrimination (tactile and kinesthetic). [Conclusion] Despite not showing significant group differences between pre and post-treatment, the neurocognitive approach could be a safe and useful strategy for recovering upper extremity movement following stroke, especially regarding affected hands, with better and longer lasting results. Although this work shows this protocol's feasibility with the panel of scales proposed, larger studies are required to demonstrate its effectiveness.

The aim of this study was to determine the feasibility, acceptability, and safety of using moxibustion for treating anorexia and improving quality of life in patients with metastatic cancer. We conducted a randomized sham-controlled trial of moxibustion. Sixteen patients with metastatic cancer were recruited from Daejeon, South Korea. The patients were randomly placed into a true or a sham moxibustion group and received 10 true or sham moxibustion treatments administered to the abdomen (CV12, CV8, CV4) and legs (ST36) over a 2-week period. Outcome measures included interest in participating in the trial, identification of successful recruitment strategies, the appropriateness of eligibility criteria, and compliance with the treatment plan (ie, attendance at treatment sessions). Clinical outcomes included results of the Functional Assessment of Anorexia/Cachexia Therapy (FAACT), answers on the European Organization for Research and Treatment of Cancer 30-item core quality of life (EORTC QLQ-C30) questionnaires, scores on the visual analogue scale (VAS), and the results from blood tests and a safety evaluation. Moxibustion was an acceptable intervention in patients with metastatic cancer. Compliance with the treatment protocol was high, with 11 patients completing all 10 treatments. No serious adverse events related to moxibustion occurred, but 4 patients in the true moxibustion group reported mild rubefaction, which disappeared in a few hours. This study suggests that moxibustion may be safely used to treat anorexia and improve quality of life in patients with metastatic cancer. However, further research is needed to confirm this result.

Background Female chronic pelvic pain (CPP) is defined as intermittent or constant pelvic or lower abdominal pain occurring in a woman for at least 6 months. Up to a quarter of women are estimated to be affected by CPP worldwide and it is responsible for one fifth of specialist gynecological referrals in the United Kingdom. Psychological interventions are commonly utilized. As waiting times and funding capacity impede access to face-to-face consultations, supported self-management (SSM) has emerged as a viable alternative. Mindfulness meditation is a potentially valuable SSM tool, and in the era of mobile technology, this can be delivered to the individual user via a smartphone app. Objective To assess the feasibility of conducting a trial of a mindfulness meditation intervention delivered by a mobile phone app for patients with CPP. The main feasibility objectives were to assess patient recruitment and app adherence, to obtain information to be used in the sample size estimate of a future trial, and to receive feedback on usability of the app. Methods Mindfulness Meditation for Women With Chronic Pelvic Pain (MEMPHIS) is a three-arm feasibility trial, that took place in two hospitals in the United Kingdom. Eligible participants were randomized in a 1:1:1 ratio to one of three treatment arms: (1) the intervention arm, consisting of a guided, spoken mindfulness meditation app; (2) an active control arm, consisting of a progressive muscle relaxation app; and (3) usual care (no app). Participants were followed-up for 6 months. Key feasibility outcomes included the time taken to recruit all patients for the study, adherence, and estimates to be used in the sample size calculation for a subsequent full-scale trial. Upon completion of the feasibility trial we will conduct focus groups to explore app usability and reasons for noncompliance. Results Recruitment for MEMPHIS took place between May 2016 and September 2016. The study was closed March 2017 and the report was submitted to the NIHR on October 26, 2017. Conclusions This feasibility trial will inform the design of a large multicentered trial to assess the clinical effectiveness of mindfulness meditation delivered via a smartphone app for the treatment of CPP.

There is non-experimental evidence that paracetamol (acetaminophen) use may increase the risk of developing asthma. However, numerous methodological issues need to be resolved before undertaking a randomized controlled trial to investigate this hypothesis. To establish the feasibility of a randomized controlled trial of liberal paracetamol as usually given by parents/guardians vs. a comparator (restricted paracetamol in accordance with WHO guidelines, ibuprofen or placebo), and childhood asthma risk. Questionnaires were completed by parents/guardians of infants admitted to Wellington Hospital with bronchiolitis to assess views about comparator treatments. Subsequently, infants of parents/guardians who provided informed consent were randomized to restricted or liberal paracetamol use for 3 months with paracetamol use recorded. Of 120 eligible participants, 72 (60%) parents/guardians completed the questionnaire. Ibuprofen, restricted paracetamol and placebo were acceptable to 42 (58%), 29 (40%) and 9 (12%) parents/guardians, respectively. 36 (30%) infants were randomized to restricted or liberal paracetamol. Paracetamol use was greater for the liberal vs. restricted group for reported [Hodges-Lehmann estimator of difference 0.94 mg/kg/day (95% CI 0.2-3.52), P = 0.02] and measured use [Hodges-Lehmann estimator of difference 2.11 mg/kg/day (95% CI 0.9-4.18), P = 0.004]. The median reported and measured use of paracetamol was 2.0-fold and 3.5-fold greater in the liberal vs. restricted group. Although separation in paracetamol dosing is likely to be achieved with a liberal vs. restricted paracetamol regime, ibuprofen is the preferred comparator treatment in the proposed RCT of paracetamol use and risk of asthma in childhood. © 2014 John Wiley & Sons Ltd.

Despite advances in adjuvant chemotherapy, 20-30% of patients in stages II-III colorectal cancer will eventually relapse. Observational studies showed a reduction in relapse rate, colon cancer-specific mortality, and overall mortality by physical activity. Results from prospective randomized interventional studies to confirm these observational data are lacking. The aims of this prospective single-arm multicenter pilot study are to evaluate feasibility and safety of exercise training after adjuvant chemotherapy in colorectal cancer patients. The training was performed three times per week for 1 year and was increased gradually in three phases until reaching 18 metabolic equivalent task hours per week. Overall, 30 patients were included. The planned training intensity could be achieved in all three phases. Patients experienced a performance increase of median 35.5 watt, a weight-loss of a median of 3.0 kg, and a reduction in body fat content of median 1.0% during this exercise training. The analysis showed early study termination due to non-compliance in 10/30 patients (33.3%), disease progression in 4 patients (13.3%), and serious adverse events in 2 patients (6.7%). About half of patients (46.7%) completed the pilot study as planned. Biomarker analysis from 20 patients showed a non-significant reduction in insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2) and insulin-like growth factor binding protein 3 (IGF-BP3) levels, significant increases in adiponectin and leptin levels, and a non-significant increase in C-peptide levels. Exercise training is feasible in patients with colorectal cancer after completion of adjuvant chemotherapy. The main problem encountered during the study was compliance. To improve compliance of exercise training, several measures were adapted for the upcoming prospective randomized ABCSG C08 Exercise II study.

Given the importance of vision in the control of walking and evidence indicating varied practice of walking improves mobility outcomes, this study sought to examine the feasibility and preliminary efficacy of varied walking practice in response to visual cues, for the rehabilitation of walking following stroke. This 3 arm parallel, multi-centre, assessor blind, randomised control trial was conducted within outpatient neurorehabilitation services. Community dwelling stroke survivors with walking speed <0.8m/s, lower limb paresis and no severe visual impairments. Over-ground visual cue training (O-VCT), Treadmill based visual cue training (T-VCT), and Usual care (UC) delivered by physiotherapists twice weekly for 8 weeks. Participants were randomised using computer generated random permutated balanced blocks of randomly varying size. Recruitment, retention, adherence, adverse events and mobility and balance were measured before randomisation, post-intervention and at four weeks follow-up. Fifty-six participants participated (18 T-VCT, 19 O-VCT, 19 UC). Thirty-four completed treatment and follow-up assessments. Of the participants that completed, adherence was good with 16 treatments provided over (median of) 8.4, 7.5 and 9 weeks for T-VCT, O-VCT and UC respectively. No adverse events were reported. Post-treatment improvements in walking speed, symmetry, balance and functional mobility were seen in all treatment arms. Outpatient based treadmill and over-ground walking adaptability practice using visual cues are feasible and may improve mobility and balance. Future studies should continue a carefully phased approach using identified methods to improve retention. Clinicaltrials.gov NCT01600391.

Decision boxes (DBoxes) are two-page evidence summaries to prepare clinicians for shared decision making (SDM). We sought to assess the feasibility of a clustered Randomized Controlled Trial (RCT) to evaluate their impact. A convenience sample of clinicians (nurses, physicians and residents) from six primary healthcare clinics who received eight DBoxes and rated their interest in the topic and satisfaction. After consultations, their patients rated their involvement in decision-making processes (SDM-Q-9 instrument). We measured clinic and clinician recruitment rates, questionnaire completion rates, patient eligibility rates, and estimated the RCT needed sample size. Among the 20 family medicine clinics invited to participate in this study, four agreed to participate, giving an overall recruitment rate of 20%. Of 148 clinicians invited to the study, 93 participated (63%). Clinicians rated an interest in the topics ranging 6.4-8.2 out of 10 (with 10 highest) and a satisfaction with DBoxes of 4 or 5 out of 5 (with 5 highest) for 81% DBoxes. For the future RCT, we estimated that a sample size of 320 patients would allow detecting a 9% mean difference in the SDM-Q-9 ratings between our two arms (0.02 ICC; 0.05 significance level; 80% power). Clinicians' recruitment and questionnaire completion rates support the feasibility of the planned RCT. The level of interest of participants for the DBox topics, and their level of satisfaction with the Dboxes demonstrate the acceptability of the intervention. Processes to recruit clinics and patients should be optimized.

'DASH for Asthma' (n 90) was a 6-month randomized controlled trial that demonstrated potential benefits of a DASH (Dietary Approaches to Stop Hypertension) behavioural intervention for improving diet quality and asthma control by comparing intervention to usual care in adults with uncontrolled asthma. The present study examined acceptability and feasibility of the intervention from the perspective of intervention participants and lifestyle coaches. Grounded in Social Cognitive Theory, the 3-month intensive stage, including three individual and eight group sessions, focused on diet modifications and behavioural self-regulation. The 3-month maintenance stage contained telephone consultations. Participants and lifestyle coaches completed surveys including 5-point Likert scales and open-ended questions. We analysed data using descriptive and inductive content analyses. Forty-six intervention participants (survey response rate was 65-72 %) and two lifestyle coaches. Participants and lifestyle coaches were highly satisfied (all mean ratings >4) with individual and group sessions. Participants identified mastery of knowledge and skills (awareness, goal setting, self-monitoring, problem solving), social learning (class members sharing experiences and ideas) and good coaching skills (reflective listening, empathy, motivational counselling) as important contributors to self-efficacy and programme satisfaction. Participants also valued personalized feedback received in individual sessions. Lifestyle coaches viewed participant engagement as a facilitator to effective sessions. Finally, participants and lifestyle coaches identified food tasting as beneficial for observational learning and facilitation of participant engagement. High class attendance and self-monitoring rate also reflected the high engagement among participants. The DASH behavioural intervention was feasible and highly acceptable to participants with uncontrolled asthma and lifestyle coaches.

Stroke provides challenges for survivors and partner caregivers. Stroke survivors and caregivers are interconnected in their emotional health, including depression, a common stroke sequelae. The purpose of this study was to develop and test the feasibility of a dyadic positive psychology-based intervention (PPI) for couples coping poststroke. Community-dwelling couples consisted of 1 partner who had a stroke ≥6 months ago and a cohabiting partner caregiver. One or both partner(s) had to report depressive symptoms. The PPI consisted of 1 brief face-to-face training session and an 8-week self-administered intervention in which participants were instructed to engage in at least 2 activities alone and 2 together each week. Two dyads were randomly assigned to a waitlist control to test feasibility of this process. Baseline, postintervention, and 3-month follow-up assessments and post-program feedback were obtained. Descriptive statistics were used to analyze sample characteristics, recruitment and retention rates, adherence, key pre- and postintervention outcomes, and satisfaction with the intervention. Eleven of 20 couples responding to recruitment letters were enrolled in the study. Ten of 11 dyads completed the program. All participants engaged in activities for at least 6 of 8 weeks. Feedback data indicated participant satisfaction with the intervention, and key outcome measures demonstrated adequate variability. The self-administered dyadic PPI is feasible for implementation with couples poststroke. The PPI represents a first step in a novel dyadic approach in this population. Recruitment, enrollment and attrition rates, and feedback will be used to inform a larger randomized trial. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Probiotics are live microorganisms that may confer health benefits when ingested. Randomized trials suggest that probiotics significantly decrease the incidence of ventilator-associated pneumonia (VAP) and the overall incidence of infection in critically ill patients. However, these studies are small, largely single-center, and at risk of bias. The aim of the PROSPECT pilot trial was to determine the feasibility of conducting a larger trial of probiotics to prevent VAP in mechanically ventilated patients in the intensive care unit (ICU). In a randomized blinded trial, patients expected to be mechanically ventilated for ≥72 hours were allocated to receive either 1 × 10(10) colony-forming units of Lactobacillus rhamnosus GG or placebo, twice daily. Patients were excluded if they were at increased risk of L. rhamnosus GG infection or had contraindications to enteral medication. Feasibility objectives were: (1) timely recruitment; (2) maximal protocol adherence; (3) minimal contamination; and (4) estimated VAP rate ≥10 %. We also measured other infections, diarrhea, ICU and hospital length of stay, and mortality. Overall, in 14 centers in Canada and the USA, all feasibility goals were met: (1) 150 patients were randomized in 1 year; (2) protocol adherence was 97 %; (3) no patients received open-label probiotics; and (4) the VAP rate was 19 %. Other infections included: bloodstream infection (19.3 %), urinary tract infections (12.7 %), and skin and soft tissue infections (4.0 %). Diarrhea, defined as Bristol type 6 or 7 stools, occurred in 133 (88.7 %) of patients, the median length of stay in ICU was 12 days (quartile 1 to quartile 3, 7-18 days), and in hospital was 26 days (quartile 1 to quartile 3, 14-44 days); 23 patients (15.3 %) died in the ICU. The PROSPECT pilot trial supports the feasibility of a larger trial to investigate the effect of L. rhamnosus GG on VAP and other nosocomial infections in critically ill patients.

The search for preventive methods to mitigate functional decline and unwanted relocation by older adults living in the community is important. Preventive home visit (PHV) models use infrequent but regular visits to older adults by trained practitioners with the goal of maintaining function and quality of life. Evidence about PHV efficacy is mixed but generally supportive. Yet interventions have rarely combined a comprehensive (biopsychosocial) occupational therapy intervention protocol with a home visit to older adults. There is a particular need in the USA to create and examine such a protocol. The study is a single-blind randomized controlled pilot trial designed to assess the feasibility, and to obtain preliminary efficacy estimates, of an intervention consisting of preventive home visits to community-dwelling older adults. An occupational therapy-based preventive home visit (PHV) intervention was developed and is being implemented and evaluated using a repeated measures design. We recruited a sample of 110 from a population of older adults (75+) who were screened and found to be at-risk for functional decline. Participants are currently living in the community (not in assisted living or a skilled nursing facility) in one of three central North Carolina counties. After consent, participants were randomly assigned into experimental and comparison groups. The experimental group receives the intervention 4 times over a 12 month follow-up period while the comparison group receives a minimal intervention of mailed printed materials. Pre- and post-intervention measures are being gathered by questionnaires administered face-to-face by a treatment-blinded research associate. Key outcome measures include functional ability, participation, life satisfaction, self-rated health, and depression. Additional information is collected from participants in the experimental group during the intervention to assess the feasibility of the intervention and potential modifiers. Fidelity is being addressed and measured across several domains. Feasibility indications to date are positive. Although the protocol has some limitations, we expect to learn enough about the intervention, delivery and effects to support a larger trial with a more stringent design and enhanced statistical power.

Leadership is important in the implementation of innovation in business, health, and allied health care settings. Yet there is a need for empirically validated organizational interventions for coordinated leadership and organizational development strategies to facilitate effective evidence-based practice (EBP) implementation. This paper describes the initial feasibility, acceptability, and perceived utility of the Leadership and Organizational Change for Implementation (LOCI) intervention. A transdisciplinary team of investigators and community stakeholders worked together to develop and test a leadership and organizational strategy to promote effective leadership for implementing EBPs. Participants were 12 mental health service team leaders and their staff (n = 100) from three different agencies that provide mental health services to children and families in California, USA. Supervisors were randomly assigned to the 6-month LOCI intervention or to a two-session leadership webinar control condition provided by a well-known leadership training organization. We utilized mixed methods with quantitative surveys and qualitative data collected via surveys and a focus group with LOCI trainees. Quantitative and qualitative analyses support the LOCI training and organizational strategy intervention in regard to feasibility, acceptability, and perceived utility, as well as impact on leader and supervisee-rated outcomes. The LOCI leadership and organizational change for implementation intervention is a feasible and acceptable strategy that has utility to improve staff-rated leadership for EBP implementation. Further studies are needed to conduct rigorous tests of the proximal and distal impacts of LOCI on leader behaviors, implementation leadership, organizational context, and implementation outcomes. The results of this study suggest that LOCI may be a viable strategy to support organizations in preparing for the implementation and sustainment of EBP.

Cardiovascular prevention is more effective if started early in life, but available interventions to promote healthy lifestyle habits among youth have been ineffective. Impulsivity in particular has proven to be an important barrier to the adoption of healthy behaviors in youth. Observational evidence suggests that mindfulness interventions may reduce impulsivity and improve diet and physical activity. We hypothesize that mindfulness training in adjunct to traditional health education will improve dietary habits and physical activity among teenagers by reducing impulsive behavior and improving planning skills. The Commit to Get Fit study is a pilot cluster randomized controlled trial examining the feasibility, acceptability and preliminary efficacy of school-based mindfulness training in adjunct to traditional health education for promotion of a healthy diet and physical activity among adolescents. Two schools in central Massachusetts (30 students per school) will be randomized to receive mindfulness training plus standard health education (HE-M) or an attention-control intervention plus standard health education (HE-AC). Assessments will be conducted at baseline, intervention completion (2 months), and 8 months. Primary outcomes are feasibility and acceptability. Secondary outcomes include physical activity, diet, impulsivity, mood, body mass index, and quality of life. This study will provide important information about feasibility and preliminary estimates of efficacy of a school-delivered mindfulness and health education intervention to promote healthy dietary and physical activity behaviors among adolescents. Our findings will provide important insights about the possible mechanisms by which mindfulness training may contribute to behavioral change and inform future research in this important area.

Our aim was to determine the feasibility and effectiveness of an individual, nurse-navigator intervention for relieving distress, anxiety, depression and health-related quality of life in women who have been treated for breast cancer (BC) and are experiencing moderate-to-severe psychological and physical symptoms. Fifty women with newly diagnosed BC who reported distress (score ≥7 on distress thermometer) before surgery were included consecutively in a pilot study and randomized 1:1 to the intervention or the control group. The intervention comprised repeated screening with patient reported outcome measures and nurse navigation. A total of 66 women who were not distressed (score <7) were followed longitudinally as an observational group. Participants filled in four questionnaires, at baseline, after 6 months and 12 months. The primary outcome was psychological distress and the secondary outcomes were anxiety, depression, health-related quality of life and feasibility of the intervention. Women in the intervention group reported significantly greater satisfaction with treatment and rehabilitation and lower levels of distress (mean 2.7 vs. 5.1, p<.01), anxiety (mean 5.1 vs. 7.8, p = .02) and depression (mean 2.2 vs. 4.4, p = .04) after 12 months compared to the control group. No significant effects were seen on health-related quality of life. The study shows promising feasibility of the individually tailored nurse-navigation intervention and while no significant effects were observed after 6 months, we did find statistically significant effects on distress, anxiety and depression 12 months after diagnosis. Our results will assist in developing rehabilitation to the most vulnerable patients.

Women taking aromatase inhibitors as treatment for breast cancer commonly experience joint pain and stiffness (aromatase inhibitor-associated arthralgia [AIAA]), which can cause problems with adherence. There is evidence that exercise might be helpful, and Nordic walking could reduce joint pain compared to normal walking. To determine the feasibility of a trial of Nordic walking as an exercise intervention for women with AIAA. A feasibility study was carried out in a sample of women with AIAA using a randomized control design. Women were randomized to exercise (six-week supervised group Nordic walking training once per week with an increasing independent element, followed by six weeks 4 × 30 minutes/week independent Nordic walking); or enhanced usual care. Data were collected on recruitment, retention, exercise adherence, safety, and acceptability. The Brief Pain Inventory, GP Physical Activity Questionnaire, and biopsychosocial measures were completed at baseline, six and 12 weeks. Forty of 159 eligible women were recruited and attrition was 10%. There was no increased lymphedema and no long-term or serious injury. Adherence was >90% for weekly supervised group Nordic walking, and during independent Nordic walking, >80% women managed one to two Nordic walking sessions per week. From baseline to study end point, overall activity levels increased and pain reduced in both the intervention and control groups. Our findings indicate that women with AIAA are prepared to take up Nordic walking, complete a six-week supervised course and maintain increased activity levels over a 12-week period with no adverse effects.

Physical activity (PA) may be important for preventing chronic diseases for adolescent and young adult (AYA) childhood cancer survivors. Randomized controlled trials (RCTs) of PA interventions for AYA survivors are sparse, but necessary to determine effective programs for increasing PA among this population. Thus, we conducted a pilot RCT, testing the feasibility of a mobile health (mHealth) intervention to promote PA among AYA survivors. We recruited 14- to 18-year-olds who were ≥1-year post cancer therapy from Seattle Children's Hospital. The 10-week intervention consisted of a wearable PA-tracking device (Fitbit Flex) and a peer-based virtual support group (Facebook group). Research staff helped set step goals and awarded badges weekly. Controls received usual care. Baseline assessments occurred before randomization and follow-up assessments occurred during weeks 8-10 of the intervention period. Feasibility criteria are defined below. Qualitative interviews assessed acceptability. Exploratory outcomes included PA, quality of life, and motivation for PA. All feasibility criteria were met: we recruited 60 survivors, intervention participants wore the Fitbit on the majority (71.5%) of intervention days, and ≥90% of all participants completed questionnaires. Qualitative data confirmed intervention acceptability. Exploratory analyses found no significant adjusted group differences for change in moderate-to-vigorous PA (4.4 vs. 5.0 min/day; P = 0.92) or sedentary time (-4.5 vs. 1.0 min/day; P = 0.73), comparing intervention subjects to controls. Some modest differences were found for select subscales of quality of life and motivation for PA. This mHealth PA intervention was feasible and acceptable to AYA childhood cancer survivors and warrants a fully powered RCT. © 2017 Wiley Periodicals, Inc.

Despite growing efforts to facilitate advance care planning (ACP) to decrease health disparities in palliative care, low completion rates of advance directives (AD) have been consistently found among African Americans. The objective was to examine the feasibility of a multicomponent ACP intervention program that integrates motivational interviewing, evidence-based ACP facilitation program (Respecting Choices(®)), and health-literacy adjusted AD. This pilot study aims to address the unique barriers to ACP engagement among African Americans in the Deep South. The design was a mixed-method randomized controlled trial design. Analysis of covariance (ANCOVA) and thematic content analysis (TCA) were conducted to identify barriers and facilitators for ACP engagement and to assess feasibility, knowledge, and intention to complete an AD. Thirty community-dwelling African Americans (mean age M = 55.43, SD = 6.71, range = 47-73) were recruited from the Deep South and randomly assigned to receive intervention (n = 15) or educational material (n = 15) at a local university medical center. All participants (n = 30) reported high satisfaction (M = 4.81, SD = 0.44, max score = 5) and increased intent to complete an AD at postintervention. A significant increase in knowledge on AD from baseline to postintervention was observed in the intervention group-t(14) = -3.06, p = 0.01, d = 1.67); no significant change was found for control. Lack of information, mistrust of doctors, and avoidance of discussing death were primary barriers to ACP discussions. Facilitators include ACP education, decreased mistrust, and proactive initiation of ongoing ACP discussions. Feasibility data revealed successful implementation of a brief intervention to increase ACP engagement and willingness to complete an AD among southern African Americans.

Physical exercises offer a variety of health benefits to cancer survivors during and post-treatment. However, exercise-based pre-habilitation is not well reported in major uro-oncology surgery. The aim of this study was to investigate the feasibility, the adherence, and the efficacy of a short-term physical pre-habilitation program to patients with invasive bladder cancer awaiting radical cystectomy (RC). A parent prospective randomized controlled clinical trial investigated efficacy of a multidisciplinary rehabilitation program on length of stay following RC. A total of 107 patients were included in the intension-to-treat population revealing 50 patients in the intervention group and 57 patients in the standard group. Pre-operatively, the intervention group was instructed to a standardized exercise program consisting of both muscle strength exercises and endurance training. The number of training sessions and exercise repetitions was patient-reported. Feasibility was expressed as adherence to the program and efficacy as the differences in muscle power within and between treatment groups at time for surgery. A total of 66 % (95 % confidence interval (CI) 51; 78) adhered more than 75 % of the recommended progressive standardized exercise program. In the intervention group, a significant improvement in muscle power of 18 % (p < 0.002) was found at time for surgery. Moreover, muscle power was significantly improved compared to that in the standard group with 0.3 W/kg (95 % CI 0.08; 0.5 %) (p < 0.006). Adherence was not associated with pre-operative BMI, nutritional risk, comorbidity, pain, gender, or age. In patients awaiting RC, a short-term exercise-based pre-habilitation intervention is feasible and effective and should be considered in future survivorship strategies.

To determine whether foot reflexology, a complementary therapy, has an effect greater than sham reflexology on induction of ovulation. Sham-controlled randomized trial with patients and statistician blinded. Infertility clinic in Plymouth, United Kingdom. Forty-eight women attending the clinic with anovulation. Women were randomized to receive eight sessions of either genuine foot reflexology or sham reflexology with gentle massage over 10 weeks. The primary outcome was ovulation detected by serum progesterone level of >30 nmol/L during the study period. Twenty-six patients were randomized to genuine reflexology and 22 to sham (one randomized patient was withdrawn). Patients remained blinded throughout the trial. The rate of ovulation during true reflexology was 11 out of 26 (42%), and during sham reflexology it was 10 out of 22 (46%). Pregnancy rates were 4 out of 26 in the true group and 2 out of 22 in the control group. Because of recruitment difficulties, the required sample size of 104 women was not achieved. Patient blinding of reflexology studies is feasible. Although this study was too small to reach a definitive conclusion on the specific effect of foot reflexology, the results suggest that any effect on ovulation would not be clinically relevant. Sham reflexology may have a beneficial general effect, which this study was not designed to detect.

To investigate and compare the feasibility, safety, and preliminary effectiveness of home-based self-managed manual wheelchair high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) programs. Eleven manual wheelchair users were randomly assigned to the HIIT ( n = 6) or the MICT group ( n = 5). Both six-week programs consisted of three 40-minute propulsion training sessions per week. The HIIT group alternated between 30 s high-intensity intervals and 60 s low-intensity intervals, whereas the MICT group maintained a constant moderate intensity. Cardiorespiratory fitness, upper limb strength, and shoulder pain were measured before and after the programs. Participants completed a questionnaire on the programs that explored general areas of feasibility. The answers to the questionnaire demonstrated that both training programs were feasible in the community. No severe adverse events occurred, although some participants experienced increased shoulder pain during HIIT. Neither program yielded a significant change in cardiorespiratory fitness or upper limb strength. However, both groups reported moderate to significant subjective improvement. Home-based wheelchair HIIT appears feasible and safe although potential development of shoulder pain remains a concern and should be addressed with a future preventive shoulder exercise program. Some recommendations have been proposed for a larger study aiming to strengthen evidence regarding the feasibility, safety, and effectiveness of HIIT.

The feasibility of utilizing the random decrement method in conjunction with a signature analysis procedure to determine the dynamic characteristics of an aeroelastic system for the purpose of on-line prediction of potential on-set of flutter was examined. Digital computer programs were developed to simulate sampled response signals of a two-mode aeroelastic system. Simulated response data were used to test the random decrement method. A special curve-fit approach was developed for analyzing the resulting signatures. A number of numerical 'experiments' were conducted on the combined processes. The method is capable of determining frequency and damping values accurately from randomdec signatures of carefully selected lengths.

Pioglitazone (PIO), a potent agonist of PPAR-gamma, is a promising candidate treatment for cocaine use disorder (CUD). We tested the effects of PIO on targeted mechanisms relevant to CUD: cocaine craving and brain white matter (WM) integrity. Feasibility, medication compliance and tolerability were evaluated. Two-arm double-blind randomized controlled proof-of-concept pilot trial of PIO or placebo (PLC). Single-site out-patient treatment research clinic in Houston, TX, USA. Thirty treatment-seeking adults, 18 to 60 years old, with CUD. Eighteen participants (8 = PIO; 10 = PLC) completed diffusion tensor imaging (DTI) of WM integrity at pre-/post-treatment. Study medication was dispensed at thrice weekly visits along with once-weekly cognitive behavioral therapy for 12 weeks. Measures of target engagement mechanisms of interest included cocaine craving assessed by the Brief Substance Craving Scale (BSCS), the Obsessive Compulsive Drug Use Scale (OCDUS), a visual analog scale (VAS) and change in WM integrity. Feasibility measures included number completing treatment, medication compliance (riboflavin detection) and tolerability (side effects, serious adverse events). Target engagement change in mechanisms of interest, defined as a ≥ 0.75 Bayesian posterior probability of an interaction existing favoring PIO over PLC, was demonstrated on measures of craving (BSCS, VAS) and WM integrity indexed by fractional anisotropy (FA) values. Outcomes indicated greater decrease in craving and greater increase in FA values in the PIO group. Feasibility was demonstrated by high completion rates among those starting treatment (21/26 = 80%) and medication compliance (≥ 80%). There were no reported serious adverse events for PIO. Compared with placebo, patients receiving pioglitazone show a higher likelihood of reduced cocaine craving and improved brain white matter integrity as a function of time in treatment. Pioglitazone shows good feasibility as a treatment for cocaine use disorder. © 2017 Society for the Study of Addiction.

To compare the feasibility of high intensity interval exercise (HI-IE) versus moderate intensity continuous exercise (MI-CE) in patients with type 2 diabetes (T2D), and to investigate the preliminary efficacy of HI-IE and MI-CE for improving glycated hemoglobin A1c (HbA1c) and body composition. Individuals with T2D were recruited and randomly assigned to HI-IE and MI-CE. Exercise training was performed 5 days per week for 12 weeks. Recruitment, retention, adherence, feeling states and self-efficacy were analyzed for feasibility. Changes in HbA1c and percent body fat from baseline were investigated at 12 weeks to determine the preliminary efficacy. Of 126 participants showing interest to join the study, 15 individuals were randomized and completed the program. No participants dropped out from the study after enrollment. Adherence rates were high and did not differ between HI-IE and MI-CE (p>0.05; >97.2% of the eligible exercise sessions for both groups). Feeling states and self-efficacy did not differ between the groups. Percent trunk fat decreased in both HI-IE and MI-CE (p=0.007 and 0.085, respectively). Total percent body fat, percent leg fat, and subcutaneous fat width were significantly reduced in both groups (p<0.05), whereas HbA1c did not change from baseline (p>0.05). The degree of improvement was similar between the interventions (p>0.05). In individuals with T2D, implementing a 12-week structured HI-IE training can be as feasible as MI-CE training. Both interventions are equally effective in lowering total body fat but have little impact on HbA1c in relatively well controlled participants with T2D. Copyright © 2012 Elsevier Ireland Ltd.

Achieving an adequate sample size is one of the major difficulties in performing post-marketing observational studies of health outcomes in persons taking specific drug preparations. We assessed the feasibility of recruiting participants for such a study of Cardizem CD from approximately 400,000 U.S. recipients of a health promotion newsletter. A three-page questionnaire was sent to a 2.5% random sample (n = 10,000) of recipients, stratified by geographic region. After two mailings, 2779 (28%) returned the questionnaire. Of the 2779 respondents, 2132 (77%) reported having high blood pressure. Eighty-seven percent indicated a willingness to participate in a long-term prospective study. In a multivariate model, calcium channel blocker (CCB) use was associated with a history of coronary heart disease, duration of hypertension medication use greater than 1 year, a rating of good or excellent hypertension care, higher systolic blood pressure, higher education level, family history of cardiovascular disease, and history of smoking. These results indicate that self-reported CCB users may be at greater risk of cardiovascular heart disease and that it is feasible to use health promotion newsletters as a source of participants in prospective studies of cardiovascular disease.

Research has shown that depressed patients suffer from reduced autobiographical memory specificity (rAMS). This cognitive phenomenon is associated with the maintenance and recurrence of depressive symptoms. This pilot study aims to investigate the feasibility and effectiveness of a relatively new group-based intervention (Memory Specificity Training; MeST) that aims to reduce rAMS in an outpatient setting. Twenty-six depressed outpatients received MeST during the waiting period prior to psychotherapy. The Client Satisfaction Questionnaire (CSQ-8) was used to measure client satisfaction after the training. The Autobiographical Memory Test (AMT) was used to measure memory specificity before and after the training. Depressive symptoms were measured using the Beck Depression Inventory (BDI-II) and the Montgomery Asberg Depression Rating Scale (MADRS), before and after the training, and at a 3-month follow-up. Participants as well as trainers were positive about the use of MeST. Participants also showed an increase in memory specificity and a decrease in depressive symptoms. This study suggests that MeST is feasible in an outpatient setting, that it increases autobiographical memory specificity and that it may decrease depressive symptoms. A randomized controlled trial is recommended to examine MeST and its effects on autobiographical memory specificity, depressive symptoms and depressive relapse more extensively. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message: Research suggests that modification of rAMS can advance recovery and reduce the chance of developing a depression relapse. However, most existing psychotherapies for depression do not include these specific interventions. This is the first study to show that MeST in an outpatient setting is feasible and can lead to an increase in autobiographical memory specificity and that it may decrease depressive symptoms. A larger scale randomized controlled trial is required to examine whether the addition of MeST to care as usual decreases depressive symptoms more effectively than care as usual without MeST, and to examine whether subgroups of patients benefit specifically from this intervention (e.g. patients with more severely decreased memory specificity).

Illness Management & Recovery (IMR) is a curriculum-based program for people with severe and persistent mental illness. To date, four randomized controlled trials (RCTs) have been published on it. As these produced mixed results, we conducted a pilot study to test the feasibility of conducting a new RCT in a Dutch psychiatric institute. Because our primary objective was to evaluate support for implementing IMR on a broader scale, we examined participant recruitment, client outcomes, and clients' and clinicians' satisfaction. Secondary objectives were to evaluate fidelity, trainers' training and supervision, and to explore program duration, dropout, and client characteristics related to dropout. For reporting, we used the checklist for pilot studies adopted from the CONSORT Statement. This program evaluation included a process-evaluation and an outcome evaluation with a One Group Pre-Posttest Design (N = 81). Interviews and internal reports were used to monitor participant numbers, program duration, dropout, and completers' characteristics. Clients' and clinicians' satisfaction and provision of trainers' training and supervision were assessed through interviews. Fidelity was assessed on the IMR Fidelity Scale; client outcomes were assessed on the IMR scale (client and clinician versions) and the Recovery Markers Questionnaire (RMQ). Eighty-one participants were recruited of 167 people who were assessed for eligibility. Completers and clinicians were satisfied, and scores for completers improved significantly on the IMR scale (clinician version) (d = 0.84) and RMQ (d = 0.52), and not significantly on the IMR scale client version (d = 0.41). Mean fidelity was good, but three groups had only moderate fidelity. Our feasibility criterion for trainers' education and supervision was partly attained. Dropout from treatment was 51 %; female participants and people who scored higher on both IMR-scales at baseline had a significantly lower chance of dropping out. The duration of IMR varied (M = 12.7 months, SD = 2.87). Results suggested that feasibility of conducting an RCT on IMR was good. Special attention is required to fidelity, IMR duration, trainers' education and supervision, and dropout, especially of men. One study limitation was our inability to conduct follow-up measurements of non-completers.

To investigate the accrual rates and recruitment processes among 3 Midwestern sites during a pilot study on manual therapy for chronic pelvic pain. Multisite pilot study for a randomized, placebo-controlled clinical trial. Three chiropractic institutions in or near major metropolitan cities in the Midwestern United States. Thirty-nine women aged 18 to 45 with chronic pelvic pain of at least 6 months duration, diagnosed by a board certified gynecologist. The method of recruitment was collected for each individual who responded to an advertisement and completed an interviewer-administered telephone screen. Participants who were willing and eligible after 3 baseline visits were entered into a randomized clinical trial. The number of responses and accrual rates were determined for the overall study, each of the 3 treatment sites, and each of the 5 recruitment efforts. In this study, 355 women were screened over the telephone and 39 were randomized, making the rate of randomization approximately 10%. The most effective recruitment methods leading to randomization were direct mail (38%) and radio advertisements (34%). However, success of the recruitment process differed by site. Based on the accrual of this multisite pilot study, a full-scale trial would not be feasible using this study's parameters. However, useful information was gained on recruitment effectiveness, eligibility criteria, and screening protocols among the 3 metropolitan sites.

Background Exposure to biomass fuel smoke is one of the leading risk factors for disease burden worldwide. International campaigns are currently promoting the widespread adoption of improved cookstoves in resource-limited settings, yet little is known about the cultural and social barriers to successful improved cookstove adoption and how these barriers affect environmental exposures and health outcomes. Design We plan to conduct a one-year crossover, feasibility intervention trial in three resource-limited settings (Kenya, Nepal and Peru). We will enroll 40 to 46 female primary cooks aged 20 to 49 years in each site (total 120 to 138). Methods At baseline, we will collect information on sociodemographic characteristics and cooking practices, and measure respiratory health and blood pressure for all participating women. An initial observational period of four months while households use their traditional, open-fire design cookstoves will take place prior to randomization. All participants will then be randomized to receive one of two types of improved, ventilated cookstoves with a chimney: a commercially-constructed cookstove (Envirofit G3300/G3355) or a locally-constructed cookstove. After four months of observation, participants will crossover and receive the other improved cookstove design and be followed for another four months. During each of the three four-month study periods, we will collect monthly information on self-reported respiratory symptoms, cooking practices, compliance with cookstove use (intervention periods only), and measure peak expiratory flow, forced expiratory volume at 1 second, exhaled carbon monoxide and blood pressure. We will also measure pulmonary function testing in the women participants and 24-hour kitchen particulate matter and carbon monoxide levels at least once per period. Discussion Findings from this study will help us better understand the behavioral, biological, and environmental changes that occur with a cookstove intervention. If this trial indicates that reducing indoor air pollution is feasible and effective in resource-limited settings like Peru, Kenya and Nepal, trials and programs to modify the open burning of biomass fuels by installation of low-cost ventilated cookstoves could significantly reduce the burden of illness and death worldwide.

Background: Twenty-four–hour urine sodium excretion is recommended for monitoring population sodium intake. Because of concerns about participation and completion, sodium excretion has not been collected previously in US nationally representative surveys. Objective: We assessed the feasibility of implementing 24-h urine collections as part of a nationally representative survey. Design: We selected a random half sample of nonpregnant US adults aged 20–69 y in 3 geographic locations of the 2013 NHANES. Participants received explicit instructions, started and ended the urine collection in a urine study mobile examination center, and answered questions about their collection. Among those with a complete 24-h urine collection, a random one-half were asked to collect a second 24-h urine sample. Sodium, potassium, chloride, and creatinine excretion were analyzed. Results: The final NHANES examination response rate for adults aged 20–69 y in these 3 study locations was 71%. Of those examined (n = 476), 282 (59%) were randomly selected to participate in the 24-h urine collection. Of these, 212 persons [75% of those selected for 24-h urine collection; 53% (equal to 71% × 75% of those selected for the NHANES)] collected a complete initial 24-h specimen and 92 persons (85% of 108 selected) collected a second complete 24-h urine sample. More men than women completed an initial collection (P = 0.04); otherwise, completion did not vary by sociodemographic characteristics, body mass index, education, or employment status for either collection. Mean 24-h urine volume and sodium excretion were 1964 ± 1228 mL and 3657 ± 2003 mg, respectively, for the first 24-h urine sample, and 2048 ± 1288 mL and 3773 ± 1891 mg, respectively, for the second collection. Conclusion: Given the 53% final component response rate and 75% completion rate, 24-h urine collections were deemed feasible and implemented in the NHANES 2014 on a subsample of adults aged 20–69 y to assess population sodium intake. This study was registered at clinicaltrials.gov as NCT02723682. PMID:27413136

Exposure to biomass fuel smoke is one of the leading risk factors for disease burden worldwide. International campaigns are currently promoting the widespread adoption of improved cookstoves in resource-limited settings, yet little is known about the cultural and social barriers to successful improved cookstove adoption and how these barriers affect environmental exposures and health outcomes. We plan to conduct a one-year crossover, feasibility intervention trial in three resource-limited settings (Kenya, Nepal and Peru). We will enroll 40 to 46 female primary cooks aged 20 to 49 years in each site (total 120 to 138). At baseline, we will collect information on sociodemographic characteristics and cooking practices, and measure respiratory health and blood pressure for all participating women. An initial observational period of four months while households use their traditional, open-fire design cookstoves will take place prior to randomization. All participants will then be randomized to receive one of two types of improved, ventilated cookstoves with a chimney: a commercially-constructed cookstove (Envirofit G3300/G3355) or a locally-constructed cookstove. After four months of observation, participants will crossover and receive the other improved cookstove design and be followed for another four months. During each of the three four-month study periods, we will collect monthly information on self-reported respiratory symptoms, cooking practices, compliance with cookstove use (intervention periods only), and measure peak expiratory flow, forced expiratory volume at 1 second, exhaled carbon monoxide and blood pressure. We will also measure pulmonary function testing in the women participants and 24-hour kitchen particulate matter and carbon monoxide levels at least once per period. Findings from this study will help us better understand the behavioral, biological, and environmental changes that occur with a cookstove intervention. If this trial indicates that reducing indoor air pollution is feasible and effective in resource-limited settings like Peru, Kenya and Nepal, trials and programs to modify the open burning of biomass fuels by installation of low-cost ventilated cookstoves could significantly reduce the burden of illness and death worldwide.

A worksite prevention program was developed to promote the work ability of construction workers and thereby prolong a healthy working life. The objective of this paper is to present the design of a randomized controlled trial evaluating the effectiveness of that intervention program compared with usual care for construction workers. The study is designed as a randomized controlled trial with a follow-up of one year. Employees eligible for this study are construction workers performing actual construction work. The worksite intervention will be compared with usual care. This intervention was developed by using the Intervention Mapping approach and consists of the following components: (1) two individual training sessions of a physical therapist to lower the physical workload, (2) a Rest-Break tool to improve the balance between work and recovery, and (3) two empowerment training sessions to increase the influence of the construction workers at the worksite. Outcome measures are assessed at baseline, 3, 6, and 12 months. The primary outcome measures of this study are work ability and health-related quality of life. Secondary outcome measures include need for recovery, musculoskeletal complaints, work engagement and self efficacy. Cost-effectiveness will be evaluated from the company perspective. Moreover, a process evaluation will be conducted. The feasibility of the intervention and the study has been enhanced by creating an intervention program that explicitly appeals to construction workers and will not interfere too much with the ongoing construction. The feasibility and effectiveness of this worksite prevention program will be investigated by means of an effect- and a process evaluation. If proven effective, this worksite prevention program can be implemented on a larger scale within the construction industry. NTR1278.

Physical activity can decrease the risk of complications related to diabetes type 2. Feasible and scalable strategies to implement support for a healthy lifestyle for patients in primary care are needed. The aim of the DiaCert-study is to evaluate a digital healthcare platform and the effect of a 12-week long smartphone-app physical activity intervention aiming at increasing physical activity (primary outcome) and improve levels of HbA1c (glycated hemoglobin), blood lipids, blood pressure, body composition, as well as other lifestyle factors and overall health in patients with diabetes type 2. The DiaCert-study is a two-arm, randomized controlled trial that will include 250 patients with diabetes type 2. At baseline, participants are randomized 1:1 to intervention, i.e. use of the smartphone-app, during 12 weeks, or to a control group receiving only standard care. Physical activity and sedentary behavior, is objectively measured using the Actigraph GT3X. Biomarkers including HbA1c and blood lipids are measured in fasting blood samples. Anthropometrics include height, weight, waist circumference and body composition, and a number of lifestyle factors including sleep, diet, self-efficacy, and quality of life, are assessed through an extensive questionnaire. Measurements are made at baseline and at follow-up after 3, 6 and 12 months. Using new technology, is one way to bridge the gap between what patients need and what health care can offer. This study evaluates a new digital health care platform and will show if use of a smartphone-app to promote daily steps is an effective and feasible method to increase physical activity and improve clinical markers in patients with diabetes type 2.

Low-income Latinas (Hispanics) face risk for cardiovascular disease due to high rates of overweight/obesity, sedentary lifestyle, and other factors. Limited access to health care and language barriers may prevent delivery of health promotion messages. Targeted approaches, including the integration of community health workers, may be required to promote healthy lifestyle and prevent chronic disease in underserved ethnic minority groups. The term commonly used to refer to female community health workers in Latino communities is "promotora(s)." This study evaluates the outcomes and feasibility of a promotora-led lifestyle behavior intervention for overweight, immigrant Latinas. A community prevention model was employed in planning and implementing this study. A randomized controlled trial design was used. A Community Advisory Board provided expertise in evaluating feasibility of study implementation in the community and other important guidance. The sample was comprised of 223 women aged 35-64 years, predominantly with low income and ≤8th grade education. The culturally tailored Lifestyle Behavior Intervention included group education (8 classes based upon Su Corazon, Su Vida), followed by 4 months of individual teaching and coaching (home visits and telephone calls). The control group received a comparable length educational program and follow-up contacts. Evaluations were conducted at baseline and at 6 and 9 months using a dietary habits questionnaire, accelerometer readings of physical activity, and clinical measures (body mass index, weight, waist circumference, blood pressure, lipids, blood glucose). Data were collected between January 2010 and August 2012. Women in the intervention group improved significantly in dietary habits, waist circumference, and physical activity in comparison to those in the control group. A treatment dosage effect was observed for weight and waist circumference. Knowledge about heart disease increased. High attendance at classes and participation in the individual teaching and counseling sessions and high retention rates support the feasibility and acceptability of the promotora-led lifestyle behavior intervention. Our findings demonstrate that lifestyle behaviors and other risk factors of overweight Latina women may be improved through a promotora-led lifestyle behavior intervention. Feasibility of implementing this intervention in community settings and engaging promotoras as facilitators is supported. Copyright © 2014 Elsevier Ltd. All rights reserved.

While lifestyle interventions involving exercise and a healthy diet in high-risk adults have been found to reduce progression to type 2 diabetes by >50%, little attention has been given to the potential benefits of such strategies in women with a history of gestational diabetes mellitus (GDM). We conducted a literature search of PubMed for English language studies of randomized controlled trials of lifestyle interventions among women with a history of GDM. In total, nine studies were identified which fulfilled the eligibility criteria. The majority of randomized trials of lifestyle interventions in women with GDM have been limited to pilot or feasibility studies. However, preliminary findings suggest that such interventions can improve diabetes risk factors in women with a history of GDM. Larger, well-designed controlled randomized trials are needed to assess the effects of lifestyle interventions on preventing subsequent progression to type 2 diabetes among women with GDM.

We evaluated the feasibility of a trial of Wii interactive video gaming, and its potential efficacy at improving cognitive functioning compared with health education, in a community sample of older adults with neuropsychologically defined mild cognitive impairment. Twenty older adults were equally randomized to either group-based interactive video gaming or health education for 90 min each week for 24 weeks. Although the primary outcomes were related to study feasibility, we also explored the effect of the intervention on neuropsychological performance and other secondary outcomes. All 20 participants completed the intervention, and 18 attended at least 80% of the sessions. The majority (80%) of participants were "very much" satisfied with the intervention. Bowling was enjoyed by the most participants and was also rated the highest among the games for mental, social, and physical stimulation. We observed medium effect sizes for cognitive and physical functioning in favor of the interactive video gaming condition, but these effects were not statistically significant in this small sample. Interactive video gaming is feasible for older adults with mild cognitive impairment, and medium effect sizes in favor of the Wii group warrant a larger efficacy trial.

Objective. To assess a text messaging intervention to promote tuberculosis (TB) treatment adherence. Methods. A mixed-methods pilot study was conducted within a public pulmonary-specialized hospital in Argentina. Patients newly diagnosed with TB who were 18 or older, and had mobile phone access were recruited and randomized to usual care plus either medication calendar (n = 19) or text messaging intervention (n = 18) for the first two months of treatment. Primary outcomes were feasibility and acceptability; secondary outcomes explored initial efficacy. Results. Feasibility was evidenced by high access to mobile phones, familiarity with texting, most phones limited to basic features, a low rate of participant refusal, and many describing suboptimal TB understanding. Acceptability was evidenced by participants indicating feeling cared for, supported, responsible for their treatment, and many self-reporting adherence without a reminder. Participants in the texting group self-reported adherence on average 77% of the days whereas only 53% in calendar group returned diaries. Exploring initial efficacy, microscopy testing was low and treatment outcomes were similar in both groups. Conclusion. The texting intervention was well accepted and feasible with greater reporting of adherence using text messaging than the diary. Further evaluation of the texting intervention is warranted.

Despite convincing evidence for early mobilization of patients on intensive care units (ICU), implementation in practice is limited. Protocols for early mobilization, including in- and exclusion criteria, assessments, safety criteria, and step schemes may increase the rate of implementation and mobilization. Patients (population) on ICUs with a protocol for early mobilization (intervention), compared to patients on ICUs without protocol (control), will be more frequently mobilized (outcome). A multicenter, stepped-wedge, cluster-randomized pilot study is presented. Five ICUs will receive an adapted, interprofessional protocol for early mobilization in randomized order. Before and after implementation, mobilization of ICU patients will be evaluated by randomized monthly one-day point prevalence surveys. Primary outcome is the percentage of patients mobilized out of bed, operationalized as a score of ≥3 on the ICU Mobility Scale. Secondary outcome parameters will be presence and/or length of mechanical ventilation, delirium, stay on ICU and in hospital, barriers to early mobilization, adverse events, and process parameters as identified barriers, used strategies, and adaptions to local conditions. Exploratory evaluation of study feasibility and estimation of effect sizes as the basis for a future explanatory study.

Almost 10 million women in the United States are caregivers for elders with dementia and many experience extreme stress that compromises their health. Acceptable and feasible interventions to teach them resourcefulness skills for managing stress may improve their health and facilitate continued caregiving. This study examined two commonly used methods for practicing skills taught during resourcefulness training (RT) to women caregivers of elders with dementia (n=63): journaling and digital voice recording. It also explored whether providing caregivers a choice between the two methods made it more acceptable or feasible. Qualitative and quantitative data were collected before, during, and after RT. Caregivers who recorded used more words (M=5446) but recorded fewer days (M=17) than those who journaled (M=2792 words and M=27 days). Similar concerns in relation to time management and practice method were expressed by women caregivers irrespective of practice method (journal versus recorder) or random versus choice condition. While journaling was more frequent than recording, more words were expressed during recordings. Perceived stress and depressive symptoms were unrelated to the number of practice days or word counts, suggesting RT acceptability and feasibility even for highly stressed or depressed caregivers. Because intervention feasibility is important for RT effectiveness testing, alternatives to the journaling and recording methods for practicing RT skills should be considered.

To introduce the rationale of a novel virtual reality system based on self-face viewing and mirror visual feedback, and to examine its feasibility as a rehabilitation tool for poststroke patients. A novel motion capture virtual reality system integrating online self-face viewing and mirror visual feedback has been developed for stroke rehabilitation.The system allows the replacement of the impaired arm by a virtual arm. Upon making small movements of the paretic arm, patients view themselves virtually performing healthy full-range movements. A sample of 6 patients in the acute poststroke phase received the virtual reality treatment concomitantly with conservative rehabilitation treatment. Feasibility was assessed during 10 sessions for each participant. All participants succeeded in operating the system, demonstrating its feasibility in terms of adherence and improvement in task performance. Patients' performance within the virtual environment and a set of clinical-functional measures recorded before the virtual reality treatment, at 1 week, and after 3 months indicated neurological status and general functioning improvement. These preliminary results indicate that this newly developed virtual reality system is safe and feasible. Future randomized controlled studies are required to assess whether this system has beneficial effects in terms of enhancing upper limb function and quality of life in poststroke patients.

Study Objectives: Despite significant medical sequelae of obstructive sleep apnea (OSA), the condition remains undiagnosed and untreated in many affected individuals. We explored the feasibility of a comprehensive, telemedicine-based OSA management pathway in a community-based Veteran cohort. Methods: This prospective, parallel-group randomized pilot study assessed feasibility of a telemedicine-based pathway for OSA evaluation and management in comparison to a more traditional, in-person care model. The study included 60 Veterans at the Philadelphia Veterans Affairs Medical Center and two affiliated community-based outpatient clinics. Telemedicine pathway feasibility, acceptability, and outcomes were assessed through a variety of quantitative (Functional Outcomes of Sleep Questionnaire, dropout rates, positive airway pressure [PAP] adherence rates, participant satisfaction ratings) and qualitative (verbal feedback) metrics. Results: There was no significant difference in functional outcome changes, patient satisfaction, dropout rates, or objectively measured PAP adherence between groups after 3 months of treatment. Telemedicine participants showed greater improvement in mental health scores, and their feedback was overwhelmingly positive. Conclusions: Our pilot study suggests that telemedicine-based management of OSA patients is feasible in terms of patient functional outcomes and overall satisfaction with care. Future studies should include larger populations to further elucidate these findings while assessing provider- and patient-related cost effectiveness.

Despite its popularity, Skype has not been tested as a tool for epidemiologic research. We examined its feasibility in Germany. A population-based sample of young adults was randomly invited to a Skype (n = 150) or a phone interview (n = 150). Response and duration of interviews were analysed to evaluate the feasibility of Skype interviews. Response was low and, with 10 % (95 % CI 5-15 %), even worse among Skype candidates, compared to 22 % (15-28 %) in the phone group. A third of the Skype group asked for being interviewed by phone. Median duration was 34.0 minutes for Skype interviews and 37.0 minutes for phone interviews. Skype is not yet a feasible tool for data collection in Germany.

To determine whether an early rehabilitation program was safe and feasible for patients during an acute exacerbation of chronic obstructive pulmonary disease (COPD). In this phase 1 randomized controlled trial, patients with an acute exacerbation of COPD admitted to the hospital were randomly allocated to a low-intensity exercise group, a moderate- to high-intensity exercise group, or a control group, who received routine physical therapy. In addition to routine physical therapy, patients in the exercise group had to participate in an exercise program. The program consisted of twice-daily aerobic and resistance exercise sessions. Primary outcomes were the number and classification of adverse events and program adherence. In 174 exercise sessions, there was 1 serious adverse event of arrhythmia in the low-intensity exercise group that resolved within 1 hour. There were 12 other minor adverse events involving 5 patients with no significant differences between groups. Patients completed an average of 80% of their scheduled sessions with no significant between-group differences. The exercise groups improved significantly in walking distance; however, no significant between-group differences were observed. There was preliminary evidence that it was safe and feasible to implement an exercise program for patients during an acute exacerbation of COPD. Additional studies with larger sample sizes are required to accurately evaluate program effectiveness.

The purpose of the present study was to examine the potential efficacy, patient acceptability, and feasibility of a novel, cognitive-behavioral therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD) who have been stabilized on medications but still show clinically significant symptoms. Thirty-one adults with ADHD and stable psychopharmacology for ADHD were randomized to CBT plus continued psychopharmacology or continued psychopharmacology alone. Assessments included ADHD severity and associated anxiety and depression rated by an independent evaluator (IE) and by self-report. At the outcome assessment, those who were randomized to CBT had lower IE-rated ADHD symptoms (p < .01) and global severity (p < .002), as well as self-reported ADHD symptoms (p < .0001) than those randomized to continued psychopharmacology alone. Those in the CBT group also had lower IE-rated and self-report anxiety (p's < .04), lower IE-rated depression (p < .01), and a trend to have lower self-reported depression (p = .06). CBT continued to show superiority over continued psychopharmacology alone when statistically controlling levels of depression in analyses of core ADHD symptoms. There were significantly more treatment responders among patients who received CBT (56%) compared to those who did not (13%) (p < .02). These data support the hypothesis that CBT for adults with ADHD with residual symptoms is a feasible, acceptable, and potentially efficacious next-step treatment approach, worthy of further testing.

Single-incision laparoscopic surgery (SILS) is an emerging minimally invasive surgery to reduce abdominal incisions. However, despite the increasing clinical application of SILS, no evidence from large-scale, randomized controlled trials is available for assessing the feasibility, short-term safety, oncological safety, and potential benefits of SILS compared with conventional laparoscopic surgery (CLS) for colorectal cancer. This is a single-center, open-label, noninferiority, randomized controlled trial. A total of 198 eligible patients will be randomly assigned to transumbilical single incision plus one port laparoscopic surgery (SILS plus one) group or to a CLS group at a 1:1 ratio. Patients ranging in age from 18 to 80 years with rectosigmoid cancer diagnosed as cT1-4aN0-2 M0 and a tumor size no larger than 5 cm are considered eligible. The primary endpoint is early morbidity, as evaluated by an independent investigator. Secondary outcomes include operative outcomes (operative time, estimated blood loss, and incision length), pathologic outcomes (tumor size, length of proximal and distal resection margins, and number of harvested lymph nodes), postoperative inflammatory and immune responses (white blood cells [WBC], neutrophil percentage [NE %], C-reactive protein [CRP], interleukin-6 [IL-6], and tumor necrosis factor-α [TNF-α]), postoperative recovery (time to first ambulation, flatus, liquid diet, soft diet, and duration of hospital stay), pain intensity, body image and cosmetic assessment, 3-year disease free survival (DFS), and 5-year overall survival (OS). Follow-up visits are scheduled for 1 and 3 months after surgery, then every 3 months for the first 2 years and every 6 months for the next 3 years. This trial will provide valuable clinical evidence for the objective assessment of the feasibility, safety, and potential benefits of SILS plus one compared with CLS for the radical resection of rectosigmoid cancer. The hypothesis is that SILS plus one is feasible for the radical resection of rectosigmoid cancer and offers short-term safety and long-term oncological safety comparable to that of CLS, and that SILS plus one offers better cosmetic results and faster convalescence compared to CLS.

For patients with advanced cancer, visits to the emergency department (ED) are common. Such patients present to the ED with a specific profile of palliative care needs, including burdensome symptoms such as pain, dyspnea, or vomiting that cannot be controlled in other settings and a lack of well-defined goals of care. The goals of this study are: i) to test the feasibility of recruiting, enrolling, and randomizing patients with serious illness in the ED; and ii) to evaluate the impact of ED-initiated palliative care on health care utilization, quality of life, and survival. This is a protocol for a single center parallel, two-arm randomized controlled trial in ED patients with metastatic solid tumors comparing ED-initiated palliative care referral to a control group receiving usual care. We plan to enroll 125 to 150 ED-advanced cancer patients at Mount Sinai Hospital in New York, USA, who meet the following criteria: i) pass a brief cognitive screen; ii) speak fluent English or Spanish; and iii) have never been seen by palliative care. We will use balanced block randomization in groups of 50 to assign patients to the intervention or control group after completion of a baseline questionnaire. All research staff performing assessment or analysis will be blinded to patient assignment. We will measure the impact of the palliative care intervention on the following outcomes: i) timing and rate of palliative care consultation; ii) quality of life and depression at 12 weeks, measured using the FACT-G and PHQ-9; iii) health care utilization; and iv) length of survival. The primary analysis will be based on intention-to-treat. This pilot randomized controlled trial will test the feasibility of recruiting, enrolling, and randomizing patients with advanced cancer in the ED, and provide a preliminary estimate of the impact of palliative care referral on health care utilization, quality of life, and survival.

Vaccines interrupting Plasmodium falciparum malaria transmission targeting sexual, sporogonic, or mosquito-stage antigens (SSM-VIMT) are currently under development to reduce malaria transmission. An international group of malaria experts was established to evaluate the feasibility and optimal design of a Phase III cluster randomized trial (CRT) that could support regulatory review and approval of an SSM-VIMT. The consensus design is a CRT with a sentinel population randomly selected from defined inner and buffer zones in each cluster, a cluster size sufficient to assess true vaccine efficacy in the inner zone, and inclusion of ongoing assessment of vaccine impact stratified by distance of residence from the cluster edge. Trials should be conducted first in areas of moderate transmission, where SSM-VIMT impact should be greatest. Sample size estimates suggest that such a trial is feasible, and within the range of previously supported trials of malaria interventions, although substantial issues to implementation exist.

This article reports on the development of a manualized occupational therapy intervention for diabetes management. An initial theoretical framework and core content areas for a Stage I intervention manual were developed based on an in-depth needs assessment and review of existing literature. After evaluation by a panel of experts and completion of a feasibility study, the intervention was revised into a Stage 2 manual in preparation for a randomized study evaluating the intervention's efficacy. In developing the initial manual, we delineated core theoretical principles to allow for flexible application and tailoring of the intervention's content areas. Expert panel feedback and feasibility study results led to changes to the intervention structure and content as we developed the Stage 2 manual. Through describing this process, we illustrate the dynamic evolution of intervention manuals, which undergo revisions due to both theoretical and practical considerations at each stage of the research-to-clinical practice pipeline.

Women with metastatic breast cancer (MBC) have average life expectancies of about 2 years, and report high levels of disease-related symptoms including pain, fatigue, sleep disturbance, psychological distress, and functional impairment. There is growing recognition of the limitations of medical approaches to managing such symptoms. Yoga is a mind-body discipline that has demonstrated a positive impact on psychological and functional health in early stage breast cancer patients and survivors, but has not been rigorously studied in advanced cancer samples. This randomized controlled trial examines the feasibility and initial efficacy of a Mindful Yoga program, compared with a social support condition that controls for attention, on measures of disease-related symptoms such as pain and fatigue. The study will be completed by December 2017. Sixty-five women with MBC age ≥ 18 are being identified and randomized with a 2:1 allocation to Mindful Yoga or a support group control intervention. The 120-min intervention sessions take place weekly for 8 weeks. The study is conducted at an urban tertiary care academic medical center located in Durham, North Carolina. The primary feasibility outcome is attendance at intervention sessions. Efficacy outcomes include pain, fatigue, sleep quality, psychological distress, mindfulness and functional capacity at post-intervention, 3-month follow-up, and 6-month follow-up. In this article, we present the challenges of designing a randomized controlled trial with long-term follow-up among women with MBC. These challenges include ensuring adequate recruitment including of minorities, limiting and controlling for selection bias, tailoring of the yoga intervention to address special needs, and maximizing adherence and retention. This project will provide important information regarding yoga as an intervention for women with advanced cancer, including preliminary data on the psychological and functional effects of yoga for MBC patients. This investigation will also establish rigorous methods for future research into yoga as an intervention for this population. ClinicalTrials.gov identifer: NCT01927081 , registered August 16, 2013.

Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications of general anesthesia in pediatrics. Aromatherapy has been shown to be effective in treating PONV in adults. Given the encouraging results of the adult studies, we planned to determine feasibility of doing a large-scale study in the pediatric population. Our group conducted a pilot randomized controlled trial examining the effect of aromatherapy on post-operative nausea and vomiting in patients 4-16 undergoing ambulatory surgery at a single center. Nausea was defined as a score of 4/10 on the Baxter Retching Faces Scale (BARF scale). A clinically significant reduction was defined as a two-point reduction in Nausea. Post operatively children were administered the BARF scale in 15 min internals until discharge home or until nausea score of 4/10 or greater. Children with nausea were randomized to saline placebo group or aromatherapy QueaseEase™ (Soothing Scents, Inc, Enterprise, AL: blend of ginger, lavender, mint and spearmint). Nausea scores were recorded post intervention. A total of 162 subjects were screened for inclusion in the study. Randomization occurred in 41 subjects of which 39 were included in the final analysis. For the primary outcome, 14/18 (78 %) of controls reached primary outcome compared to 19/21 (90 %) in the aromatherapy group (p = 0.39, Eta 0.175). Other outcomes included use of antiemetic in PACU (control 44 %, aromatherapy 52 % P = 0.75, Eta 0.08), emesis (Control 11 %, 9 % aromatherapy, P = 0.87, Eta = 0.03). There was a statistically significant difference in whether subjects continued to use the intervention (control 28 %, aromatherapy 66 %, p-value 0.048, Eta 0.33). Aromatherapy had a small non-significant effect size in treating postoperative nausea and vomiting compared with control. A large-scale randomized control trial would not be feasible at our institution and would be of doubtful utility. ClinicalTrials.gov NCT02663154 .

To determine the feasibility, the cluster design effect and the variance and minimal clinical importance difference in the primary outcome in a pilot study of a structured approach to goal-setting. A cluster randomized controlled trial. Inpatient rehabilitation facilities. People who were admitted to inpatient rehabilitation following stroke who had sufficient cognition to engage in structured goal-setting and complete the primary outcome measure. Structured goal elicitation using the Canadian Occupational Performance Measure. Quality of life at 12 weeks using the Schedule for Individualised Quality of Life (SEIQOL-DW), Functional Independence Measure, Short Form 36 and Patient Perception of Rehabilitation (measuring satisfaction with rehabilitation). Assessors were blinded to the intervention. Four rehabilitation services and 41 patients were randomized. We found high values of the intraclass correlation for the outcome measures (ranging from 0.03 to 0.40) and high variance of the SEIQOL-DW (SD 19.6) in relation to the minimally importance difference of 2.1, leading to impractically large sample size requirements for a cluster randomized design. A cluster randomized design is not a practical means of avoiding contamination effects in studies of inpatient rehabilitation goal-setting. Other techniques for coping with contamination effects are necessary.

This single-subject design study evaluated the feasibility and efficacy of passive and interactive videogame distraction on behavioral distress for a preschool-aged child receiving repeated burn dressing changes. A 4-year-old girl underwent 3 baseline and 10 videogame distraction sessions (5 passive and 5 interactive) using a restricted alternating treatments design. Observed behavioral distress was coded, and parents and nurses rated the child's distress and cooperative behavior. Relative to baseline, behavioral distress decreased and cooperative behavior increased immediately after the onset of videogame distraction. Single Case Randomization Tests revealed significantly lower behavioral distress and greater cooperation during interactive videogame distraction relative to passive videogame distraction. Interactive videogame distraction appears to be a feasible and effective pain management strategy for a preschool-aged child undergoing repeated painful medical procedures.

Targeted treatment, matched according to specific clinical criteria e.g. hip muscle weakness, may result in better outcomes for people with patellofemoral pain (PFP). However, to ensure the success of future trials, a number of questions on the feasibility of a targeted treatment need clarification. The aim of the study was to explore the feasibility of matched treatment (MT) compared to usual care (UC) management for a subgroup of people with PFP determined to have hip weakness and to explore the mechanism of effect for hip strengthening. In a pragmatic, randomised controlled feasibility study, 24 participants with PFP (58% female; mean age 29 years) were randomly allocated to receive either MT aimed specifically at hip strengthening, or UC over an eight-week period. The primary outcomes were feasibility outcomes, which included rates of adherence, attrition, eligibility, missing data and treatment efficacy. Secondary outcomes focused on the mechanistic outcomes of the intervention, which included hip kinematics. Conversion to consent (100%), missing data (0%), attrition rate (8%) and adherence to both treatment and appointments (>90%) were deemed successful endpoints. The analysis of treatment efficacy showed that the MT group reported a greater improvement for the Global Rating of Change Scale (62% vs. 9%) and the Anterior Knee Pain Scale (-5.23 vs. 1.18) but no between-group differences for either average or worst pain. Mechanistic outcomes showed a greatest reduction in peak hip internal rotation angle for the MT group (13.1% vs. -2.7%). This feasibility study indicates that a definitive randomised controlled trial investigating a targeted treatment approach is achievable. Findings suggest the mechanism of effect of hip strengthening may be to influence kinematic changes in hip function in the transverse plane. This study was registered retrospectively.

Bayesian network meta-analysis for cluster randomized trials with binary outcomes.
Uhlmann, Lorenz; Jensen, Katrin; Kieser, Meinhard
2017-06-01
Network meta-analysis is becoming a common approach to combine direct and indirect comparisons of several treatment arms. In recent research, there have been various developments and extensions of the standard methodology. Simultaneously, cluster randomized trials are experiencing an increased popularity, especially in the field of health services research, where, for example, medical practices are the units of randomization but the outcome is measured at the patient level. Combination of the results of cluster randomized trials is challenging. In this tutorial, we examine and compare different approaches for the incorporation of cluster randomized trials in a (network) meta-analysis. Furthermore, we provide practical insight on the implementation of the models. In simulation studies, it is shown that some of the examined approaches lead to unsatisfying results. However, there are alternatives which are suitable to combine cluster randomized trials in a network meta-analysis as they are unbiased and reach accurate coverage rates. In conclusion, the methodology can be extended in such a way that an adequate inclusion of the results obtained in cluster randomized trials becomes feasible. Copyright © 2016 John Wiley & Sons, Ltd.

Background Based on the self-efficacy theory, an online and a face-to-face self-management programs ‘Challenge your Arthritis’ for young adults with a rheumatic disease have recently been developed. These two courses are led by young peer leaders. The objective of this study was to test the feasibility of the online and face-to-face self-management program. Methods Feasibility was evaluated on items of perceived usefulness, perceived ease of use, user-acceptance, and adherence to both programs in young adults and peer leaders. Additional analyses of interactions on the e-Health applications, discussion board and chat board, were conducted. Results Twenty-two young adults with a diagnosed rheumatic disease participated in the study: 12 young adults followed the online program and 10 followed the face-to-face program. Both programs appeared to be feasible, especially in dealing with problems in daily life, and the participants indicated the time investment as ‘worthwhile’. In using the online program, no technical problems occurred. Participants found the program easy to use, user friendly, and liked the ‘look and feel’ of the program. Conclusions Both the online and the face-to-face versions of a self-management program. ‘Challenge your arthritis’ were found to be feasible and well appreciated by young adults with a rheumatic disease. Because these programs are likely to be a practical aid to health practices, a randomized controlled study to investigate the effects on patient outcomes is planned. PMID:24666817

This pilot randomized controlled trial aimed to determine the feasibility, acceptability, and preliminary efficacy of parental problem solving skills training (PSST) compared to treatment as usual (TAU) on improving parental mental health symptoms, physical health and well-being, and parenting behaviors. Effects of parent PSST on child outcomes (pain, emotional and physical functioning) were also examined. Participants included 61 parents of children aged 10–17 years with chronic pain randomized to PSST (n = 31) or TAU (n = 30). Parents receiving PSST participated in 4–6 individual sessions of training in problem solving skills. Outcomes were assessed at pre-treatment, immediately post-treatment, and at 3-month follow up. Feasibility was determined by therapy session attendance, therapist ratings, and parent treatment acceptability ratings. Feasibility of PSST delivery in this population was demonstrated by high compliance with therapy attendance, excellent retention, high therapist ratings of treatment engagement, and high parent ratings of treatment acceptability. PSST was associated with post-treatment improvements in parental depression (d = −0.68), general mental health (d = 0.64), and pain catastrophizing (d = −0.48), as well as in child depression (d = −0.49), child general anxiety (d = −0.56), and child pain-specific anxiety (d = −0.82). Several effects were maintained at 3-month follow-up. Findings demonstrate that PSST is feasible and acceptable to parents of youth with chronic pain. Treatment outcome analyses show promising but mixed patterns of effects of PSST on parent and child mental health outcomes. Further rigorous trials of PSST are needed to extend these pilot results.

To evaluate the feasibility and safety of a home-based exercise programme for people with Alzheimer's disease, and to provide preliminary evidence of programme effectiveness in improving balance and mobility and reducing falls risk. A randomized controlled trial. Community. Forty people with mild to moderate Alzheimer's disease (mean age 81.9, SD 5.72; 62.5% female). Participants were randomized to a six-month home-based individually tailored balance, strengthening and walking exercise programme (physiotherapist) or a six-month home-based education programme (control) (occupational therapist). Both programmes provided six home-visits and five follow-up phone calls. Balance, mobility, falls and falls risk were measured at baseline and programme completion. Intention-to-treat analysis using a generalized linear model with group allocation as a predictor variable was performed to evaluate programme effectiveness. Feasibility and adverse events were systematically recorded at each contact. Fifty-eight per cent of the exercise group finished the programme, completing an average of 83% of prescribed sessions, with no adverse events reported. Functional Reach improved significantly (P = 0.002) in the exercise group (mean (SD), 2.28 (4.36)) compared to the control group (-2.99 (4.87)). Significant improvement was also observed for the Falls Risk for Older People - Community score (P = 0.008) and trends for improvement on several other balance, mobility, falls and falls risk measures for the exercise group compared to the control group. The exercise programme was feasible and safe and may help improve balance and mobility performance and reduce falls risk in people with Alzheimer's disease.
A tutorial on pilot studies: the what, why and how
2010-01-01
Pilot studies for phase III trials - which are comparative randomized trials designed to provide preliminary evidence on the clinical efficacy of a drug or intervention - are routinely performed in many clinical areas. Also commonly know as "feasibility" or "vanguard" studies, they are designed to assess the safety of treatment or interventions; to assess recruitment potential; to assess the feasibility of international collaboration or coordination for multicentre trials; to increase clinical experience with the study medication or intervention for the phase III trials. They are the best way to assess feasibility of a large, expensive full-scale study, and in fact are an almost essential pre-requisite. Conducting a pilot prior to the main study can enhance the likelihood of success of the main study and potentially help to avoid doomed main studies. The objective of this paper is to provide a detailed examination of the key aspects of pilot studies for phase III trials including: 1) the general reasons for conducting a pilot study; 2) the relationships between pilot studies, proof-of-concept studies, and adaptive designs; 3) the challenges of and misconceptions about pilot studies; 4) the criteria for evaluating the success of a pilot study; 5) frequently asked questions about pilot studies; 7) some ethical aspects related to pilot studies; and 8) some suggestions on how to report the results of pilot investigations using the CONSORT format.

Clinically effective and cost-effective methods for managing problematic sexual behaviour in adolescents are urgently needed. Adolescents who show problematic sexual behaviour have a range of negative psychosocial outcomes, and they and their parents can experience stigma, hostility and rejection from their community. Multisystemic therapy (MST) shows some evidence for helping to reduce adolescent sexual reoffending and is one of the few promising interventions available to young people who show problematic sexual behaviour. This paper describes the protocol for Services for Teens Engaging in Problem Sexual Behaviour (STEPS-B), a feasibility trial of MST for problem sexual behaviour (MST-PSB) in antisocial adolescents at high risk of out-of-home placement due to problematic sexual behaviour. Eighty participants and their families recruited from five London boroughs will be randomized to MST-PSB or management as usual with follow-up to 20 months post-randomization. The primary outcome is out-of-home placement at 20 months. Secondary outcomes include sexual and non-sexual offending rates and antisocial behaviours, participant well-being, educational outcomes and total service and criminal justice sector costs. Feasibility outcomes include mapping the clinical service pathways needed to recruit adolescents displaying problematic sexual behaviour, acceptability of a randomized controlled trial to the key systems involved in managing these adolescents, and acceptability of the research protocol to young people and their families. Data will be gathered from police computer records, the National Pupil Database and interviews and self-report measures administered to adolescents and parents and will be analysed on an intention-to-treat basis. The STEPS-B feasibility trial aims to inform policymakers, commissioners of services and professionals about the potential for implementing MST-PSB as an intervention for adolescents showing problem sexual behaviour. Should MST-PSB show potential, STEPS-B will determine what would be necessary to implement the programme more fully and at a scale that would warrant a full trial.

Inflammatory arthritis leads to work disability, absenteeism and presenteeism (i.e. at-work productivity loss) at high cost to individuals, employers and society. A trial of job retention vocational rehabilitation (VR) in the United States identified this helped people keep working. The effectiveness of this VR in countries with different socioeconomic policies and conditions, and its impact on absenteeism, presenteeism and health, are unknown. This feasibility study tested the acceptability of this VR, modified for the United Kingdom, compared to written advice about managing work problems. To help plan a randomized controlled trial, we tested screening, recruitment, intervention delivery, response rates, applicability of the control intervention and identified the relevant primary outcome. A feasibility randomized controlled trial with rheumatoid, psoriatic or inflammatory arthritis patients randomized to receive either job retention VR or written information only (the WORK-IA trial). Following three days VR training, rheumatology occupational therapists provided individualised VR on a one to one basis. VR included work assessment, activity diaries and action planning, and (as applicable) arthritis self-management in the workplace, ergonomics, fatigue and stress management, orthoses, employment rights and support services, assistive technology, work modifications, psychological and disclosure support, workplace visits and employer liaison. Fifty five (10%) people were recruited from 539 screened. Follow-up response rates were acceptable at 80%. VR was delivered with fidelity. VR was more acceptable than written advice only (7.8 versus 6.7). VR took on average 4 h at a cost of £135 per person. Outcome assessment indicated VR was better than written advice in reducing presenteeism (Work Limitations Questionnaire (WLQ) change score mean: VR = -12.4 (SD 13.2); control = -2.5 (SD 15.9), absenteeism, perceived risk of job loss and improving pain and health status, indicating proof of concept. The preferred primary outcome measure was the WLQ, a presenteeism measure. This brief job retention VR is a credible and acceptable intervention for people with inflammatory arthritis with concerns about continuing to work due to arthritis. ISRCTN 76777720 .

Dengue infection is the fastest spreading mosquito-borne viral disease in the world. One of the complications of dengue is dehydration which, if not carefully monitored and treated, may lead to shock, particularly in those with dengue haemorrhagic fever. WHO has recommended oral fluid intake of five glasses or more for adults who are suspected to have dengue fever. However, there have been no published studies looking at self-care intervention measures to improve oral fluid intake among patients suspected of dengue fever. To assess the feasibility and effectiveness of using a fluid chart to improve oral fluid intake in patients with suspected dengue fever in a primary care setting. This feasibility study used a randomized controlled study design. The data was collected over two months at a primary care clinic in a teaching hospital. The inclusion criteria were: age > 12 years, patients who were suspected to have dengue fever based on the assessment by the primary healthcare clinician, fever for > three days, and thrombocytopenia (platelets < 150 x 109/L). Both groups received a dengue home care card. The intervention group received the fluid chart and a cup (200ml). Baseline clinical and laboratory data, 24-hour fluid recall (control group), and fluid chart were collected. The main outcomes were: hospitalization rates, intravenous fluid requirement and total oral fluid intake. Among the 138 participants who were included in the final analysis, there were fewer hospital admissions in the intervention group (n = 7, 10.0%) than the control group (n = 12, 17.6%) (p = 0.192). Similarly, fewer patients (n = 9, 12.9%) in the intervention group required intravenous fluid compared to the control group (n = 15, 22.1%), (p = 0.154). There was an increase in the amount of daily oral fluid intake in the intervention group (about 3,000 ml) compared to the control group (about 2,500 ml, p = 0.521). However, these differences did not reach statistical significance. This is a feasible and acceptable study to perform in a primary care setting. The fluid chart is a simple, inexpensive tool that may reduce hospitalization and intravenous fluid requirement in suspected dengue patients. A randomized controlled trial with larger sample size is needed to determine this conclusively.

Guidelines recommend routine universal HIV testing in adults to reduce the pool of infected patients unaware of their status, without specific recommendations concerning the method. We compared acceptability and feasibility of HIV testing by ELISA tests or rapid tests from finger-stick whole blood. Prospective randomized multi-center study comparing acceptability and feasibility of routine universal HIV testing by ELISA tests, with a charge, subsequently reimbursed by Social Security for affiliated patients, or rapid tests from finger-stick whole blood, without any charge from the patients or the general practitioner for the study. A single investigator performed all interventions. After consent, all adults (18-70 years old) consulting their general practitioner in Paris, France, unaware of their status, were enrolled. Testing was performed immediately for the patients in the rapid test arm; a prescription was given for testing in a lab for the patients in the ELISA arm. The primary endpoint was acceptability of each method. The secondary endpoint was feasibility of each method, assessed one month after the consultation. Two hundred and seventy patients were enrolled: 133 patients in the ELISA arm, 137 in the rapid test arm. Acceptability of the rapid test (92%) was higher than that of the ELISA (63.9%), P<0.0001. Feasibility of the rapid test (100%) was higher than that of the ELISA (50.5%), P<0.0001. A center effect was shown concerning feasibility of ELISA but not concerning feasibility of rapid tests. Rapid testing from finger-stick whole blood is more acceptable and feasible than ELISA for routine universal HIV testing. A larger use of rapid tests, ideally free of charge, by general practitioners could reduce the pool of infected patients unaware of their status. Copyright © 2018 Elsevier Masson SAS.

Social networks are increasingly recognized as important points of intervention, yet relatively few intervention studies of respiratory infection transmission have utilized a network design. Here we describe the design, methods, and social network structure of a randomized intervention for isolating respiratory infection cases in a university setting over a 10-week period. 590 students in six residence halls enrolled in the eX-FLU study during a chain-referral recruitment process from September 2012-January 2013. Of these, 262 joined as "seed" participants, who nominated their social contacts to join the study, of which 328 "nominees" enrolled. Participants were cluster-randomized by 117 residence halls. Participants were asked to respond to weekly surveys on health behaviors, social interactions, and influenza-like illness (ILI) symptoms. Participants were randomized to either a 3-Day dorm room isolation intervention or a control group (no isolation) upon illness onset. ILI cases reported on their isolation behavior during illness and provided throat and nasal swab specimens at onset, day-three, and day-six of illness. A subsample of individuals (N=103) participated in a sub-study using a novel smartphone application, iEpi, which collected sensor and contextually-dependent survey data on social interactions. Within the social network, participants were significantly positively assortative by intervention group, enrollment type, residence hall, iEpi participation, age, gender, race, and alcohol use (all P<0.002). We identified a feasible study design for testing the impact of isolation from social networks in a university setting. These data provide an unparalleled opportunity to address questions about isolation and infection transmission, as well as insights into social networks and behaviors among college-aged students. Several important lessons were learned over the course of this project, including feasible isolation durations, the need for extensive organizational efforts, as well as the need for specialized programmers and server space for managing survey and smartphone data.

The role of endoscopic preoperative biliary drainage (PBD) for pancreatic head cancer is controversial because of the high incidence of stent occlusion before surgery. This study was performed to evaluate the feasibility and safety of PBD using a fully covered self-expandable metallic stent (FCSEMS). This multicenter prospective study involved 26 patients treated for pancreatic head cancer with distal bile duct obstruction from April 2011 to March 2013. An FCSEMS was endoscopically placed in 24 patients. Among these, 7 patients were diagnosed with unresectable cancer, and 17 underwent surgery at a median of 18 days after FCSEMS placement. The main outcome measure was preoperative and postoperative adverse events. Two adverse events (cholecystitis and insufficient resolution of jaundice) occurred between FCSEMS placement and surgery (12%). Postoperative adverse events occurred in eight patients (47%). The cumulative incidence of stent-related adverse events 4 and 8 weeks after FCSEMS placement among the 24 patients who underwent this procedure were 19%. PBD using an FCSEMS is feasible in patients with resectable pancreatic head cancer. Placement of an FCSEMS can be an alternative PBD technique when surgery without delay is impossible. A larger randomized controlled trial is warranted.

This study presents findings from a pilot randomized controlled trial, testing a 12-week intervention to train parents of youth with autism spectrum disorder (ASD) to advocate for adult disability services—the Volunteer Advocacy Project-Transition (VAP-T). Participants included 41 parents of youth with ASD within two years of high school exit, randomly assigned to a treatment (N = 20) or wait-list control (N = 21) group. Outcomes, collected before and after the intervention, included parental knowledge about adult services, advocacy skills-comfort, and empowerment. The VAP-T had acceptable feasibility, treatment fidelity, and acceptability. After participating in the VAP-T, intervention parents (compared to controls) knew more about the adult service system, were more skilled/comfortable advocating, and felt more empowered.

A new microscopic 3D Potts interaction financial price model is established in this work, to investigate the nonlinear complexity behaviors of stock markets. 3D Potts model, which extends the 2D Potts model to three-dimensional, is a cubic lattice model to explain the interaction behavior among the agents. In order to explore the complexity of real financial markets and the 3D Potts financial model, a new random coarse-grained Lempel-Ziv complexity is proposed to certain series, such as the price returns, the price volatilities, and the random time d-returns. Then the composite multiscale entropy (CMSE) method is applied to the intrinsic mode functions (IMFs) and the corresponding shuffled data to study the complexity behaviors. The empirical results indicate that the 3D financial model is feasible.

This pilot randomized trial tested the feasibility and efficacy of supplementing residential substance-abuse treatment for new mothers with a brief, yet rigorous, attachment-based parenting program. Twenty-one predominantly (86%) White mothers and their infants living together in residential substance-abuse treatment were randomly assigned to the program (n = 11) or control (n = 10) group. Program mothers received 10 home-based sessions of Dozier’s Attachment and Biobehavioral Catch-up (ABC) intervention. Postintervention observations revealed more supportive parenting behaviors among the randomly assigned ABC mothers. PMID:25424409

Phase randomization is a very important assumption in the BB84 quantum key distribution (QKD) system with weak coherent source; otherwise, eavesdropper may spy the final key. In this Letter, a stable and monitored active phase randomization scheme for the one-way and two-way QKD system is proposed and demonstrated in experiments. Furthermore, our scheme gives an easy way for Alice to monitor the degree of randomization in experiments. Therefore, we expect our scheme to become a standard part in future QKD systems due to its secure significance and feasibility.

The aim of this study was to evaluate the feasibility and acceptability of "Cascade": an online, group-based, cognitive behavioral therapy intervention, delivered "live" by a psychologist, to assist parents of children who have completed cancer treatment. Forty-seven parents were randomized to Cascade (n = 25) or a 6-month waitlist (n = 22). Parents completed questionnaires at baseline, 1-2 weeks and 6 months post-intervention. Thirty parents completed full evaluations of the Cascade program (n = 21 randomized to Cascade, n = 9 completed Cascade post-waitlist). Ninety-six percent of Cascade participants completed the intervention (n = 24/25). Eighty percent of parents completed every questionnaire (mean completion time 25 min (SD = 12)). Cascade was described as at least "somewhat" helpful by all parents. None rated Cascade as "very/quite" burdensome. Parents reported that the "online format was easy to use" (n = 28, 93.3 %), "I learnt new skills" (n = 28, 93.3 %), and "I enjoyed talking to others" (n = 29, 96.7 %). Peer-to-peer benefits were highlighted by good group cohesion scores. Cascade is highly acceptable and feasible. Its online delivery mechanism may address inequities in post-treatment support for parents, a particularly acute concern for rural/remote families. Future research needs to establish the efficacy of the intervention. ACTRN12613000270718, https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12613000270718.

Meta-analysis of time-to-event data has proved difficult in the past because consistent summary statistics often cannot be extracted from published results. The use of individual patient data allows for the re-analysis of each study in a consistent fashion and thus makes meta-analysis of time-to-event data feasible. Time-to-event data can be…

The aim of this study was to assess the feasibility of a self-management intervention targeting cognitive dysfunction to improve quality of life and reduce memory-related disability in adults with epilepsy. The intervention incorporates (1) education on cognitive function in epilepsy, (2) self-awareness training, (3) compensatory strategies, and (4) application of these strategies in day-to-day life using problem-solving therapy. In addition to the behavioral modification, formal working memory training was conducted by utilizing a commercially available program in a subgroup of patients. Our findings suggest that a self-management intervention targeting cognitive dysfunction was feasible for delivery to a rural population with epilepsy, with 13 of 16 enrolled participants completing the 8-session program. Qualitative data indicate high satisfaction and subjective improvement in cognitive functioning in day-to-day life. These findings provide support for further evaluation of the efficacy of this intervention through a randomized controlled trial. Copyright © 2015 Elsevier Inc. All rights reserved.

This controlled, non-randomized study explored the feasibility of introducing a Combined Individual and Group Intervention (CIGI) for users with mental disorders in residential facilities, and tested whether users who received the CIGI had better functioning than users who received the Treatment-As-Usual (TAU), at two-year follow up. In the CIGI, a structured cognitivebehavioral approach called VADO (in English, Skills Assessment and Definition of Goals) was used to set specific goals with each user, while Falloon's psychoeducational treatment was applied with the users as a group. Thirty-one professionals attended a training course in CIGI, open to users' voluntary participation, and applied it for two years with all users living in 8 residential facilities of the Mental Health Department of Modena, Italy. In the same department, 5 other residential facilities providing TAU were used as controls. ANOVA for repeated measures showed a significant interaction effect between users' functioning at baseline and follow up assessments, and the intervention. In particular, change in global functioning was higher in the 55 CIGI users than in the 44 TAU users. These results suggest that CIGI can be successfully introduced in residential facilities and may be useful to improve functioning in users with severe mental disorders. Copyright © 2016.

The aim of the study was to assess clinical feasibility and tolerance of concentrated preterm formula at 30 kcal/oz (CPF30) to fortify human milk to a caloric density of 24 kcal/oz, compared to conventional powdered human milk fortifier (PHMF). Very low birth weight neonates were stratified by birth weight and randomized to receive human milk fortification using CPF30 or PHMF. Infants were monitored from first introduction of human milk fortification, until fortified feeds were well tolerated. Primary outcome was weight gain; secondary outcomes included other measures of feeding intolerance (residual gastric aspirates, feeds held, prokinetic therapy), sepsis, and death. The clinical and study personnel were blinded to the intervention. No significant differences in weight gain or other measures of feeding tolerance were demonstrated between CPF30 and PHMF. Macronutrient intake was similar between both groups. Infants with a birth weight of ≥ 1000 g who received CPF30, experienced fewer days NPO (nil per os; nothing per mouth) and a trend toward lower incidence of NEC, compared with those who received PHMF.. The amount of human milk consumed was significantly lower in the CPF30 group. Both fortifiers were similarly well tolerated. Fortification of human milk with CPF30 is a safe and feasible alternative to conventional PHMF.

The aim of the present study was to test the feasibility of Internet interventions among nulliparous women suffering from severe fear of childbirth (FOC) by means of an Internet-delivered therapist-supported self-help program based on cognitive behavioral therapy (ICBT). Prospective, longitudinal cohort study. A feasibility study of an ICBT program for the treatment of severe FOC in pregnant women. Twenty-eight Swedish-speaking nulliparous women with severe FOC recruited via a project home page from January 2012 to December 2013. The main components of the ICBT program for the treatment of severe FOC comprised psycho-education, breathing retraining, cognitive restructuring, imaginary exposure, in vivo exposure and relapse prevention. The study participants were anonymously self-recruited over the Internet, interviewed by telephone and then enrolled. All participants were offered 8 weeks of treatment via the Internet. Participants reported their homework weekly, submitted measurements of their fear and received feedback from a therapist via a secure online contact management system. Level of FOC measured with the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ A) during screening at enrollment and weekly during the treatment (W-DEQ version A), and after the delivery (W-DEQ version B). A statistically significant (p < 0.0005) decrease of FOC [W-DEQ sum score decreased pre to post-therapy, with a large effect size (Cohen's d = 0.95)]. The results of this feasibility study suggest that ICBT has potential in the treatment of severe FOC during pregnancy in motivated nulliparous women. The results need to be confirmed by randomized controlled studies.

Background The feasibility of telemedicine in diagnosing and treating nonacute headaches, such as primary headaches (migraine and tension-type) and medication-overuse headaches has not been previously investigated. By eliminating the need of travel to specialists, telemedicine may offer significant time and money savings. Objectives Our objective was to estimate the acceptance of telemedicine and investigate the feasibility and cost savings of telemedicine consultations in diagnosing and treating nonacute headaches. Methods From September 2012 to March 2015, nonacute headache patients from Northern Norway who were referred to neurologists through an electronic application system were consecutively screened and randomized to participate in either telemedicine or traditional specialist visits. All patients were consulted by two neurologists at the neurological department in Tromsø University Hospital. Feasibility outcomes were compared between telemedicine and traditional groups. Baseline characteristics and costs were then compared between rural and urban patients. Travel costs were calculated by using the probabilistic method of the Norwegian traveling agency: the cheapest means of public transport for each study participant. Loss of pay was calculated based on the Norwegian full-time employee’s average salary: < 3.5 hours=a half day’s salary, > 3.5 hours spent on travel and consultation=one day’s salary. Distance and time spent on travel were estimated by using Google Maps. Results Of 557 headache patients screened, 479 were found eligible and 402 accepted telemedicine participation (83.9%, 402/479) and were included in the final analyses. Of these, 202 received traditional specialist consultations and 200 received telemedicine. All patients in the telemedicine group were satisfied with the video quality, and 198 (99%, 198/200) were satisfied with the sound quality. The baseline characteristics as well as headache diagnostics and follow-up appointments, and the investigation, advice, and prescription practices were not statistically different between the two randomized groups. In addition, telemedicine consultations were shorter than traditional visits (38.8 vs 43.7 min, P<.001). The travel cost per rural individual (292/402, 73%) was €249, and estimated lost income was €234 per visit. The travel cost in the urban area (110/402, 27%) was €6, and estimated lost income was €117 per visit. The median traveling distance for rural patients was 526 km (range 1892 km), and the median traveling time was 7.8 hours (range 27.3 hours). Rural patients had a longer waiting time than urban patients (64 vs 47 days, P=.001), and fewer women were referred from rural areas (P=.04). Rural women reported higher pain scores than urban women (P=.005). Conclusion Our study shows that telemedicine is an accepted, feasible, time-saving, and cost-saving alternative to traditional specialist consultations for nonacute headaches.

Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious illness of biological origin characterized by profound physical and cognitive exhaustion and postexertion malaise. Pacing is a common strategy used to manage available energy and complete activities of daily living; yet little research has investigated this as a strategy to increase physical activity levels. Typically, people living with ME/CFS are faced by unique barriers to physical activity participation and are less physically active than healthy peers. As such they are at increased risk of physical inactivity–related health consequences. Active video games may be a feasible and acceptable avenue to deliver physical activity intervention by overcoming many of the reported barriers to participation. Objective The primary objective of this pilot study is to determine the feasibility and acceptability of active video games to increase physical activity levels of people with ME/CFS. The secondary aims are to explore the preliminary effectiveness of pacing and active video gaming to pacing alone and pacing plus conventional physical activity to increase the physical activity levels of adults with ME/CFS and explore the relationship between physical activity and cumulative inflammatory load (allostatic load). Methods This study will use a mixed method design, with a 3-arm pilot randomized controlled trial, exit interviews, and collection of feasibility and process data. A total of 30 adults with ME/CFS will be randomized to receive either (1) pacing, (2) pacing and conventional physical activity, or (3) pacing and active video gaming. The intervention duration will be 6 months, and participants will be followed up for 6 months postintervention completion. The intervention will be conducted in the participant’s home, and activity intensity will be determined by continuously monitored heart rate and ratings of perceived exertion. Feasibility and acceptability and process data will be collected during and at the end of the intervention. Health-related outcomes (eg, physical activity, blood samples, quality of life, and functioning) will be collected at baseline, end of intervention, and 6 months after intervention completion. Results This protocol was developed after 6 months of extensive stakeholder and community consultation. Enrollment began in January 2017; as of publication, 12 participants were enrolled. Baseline testing is scheduled to commence in mid-2017. Conclusions This pilot study will provide essential feasibility and acceptability data which will guide the use of active video games for people with ME/CFS to increase their physical activity levels. Physical activity promotion in this clinical population has been poorly and under-researched, and any exploration of alternative physical activity options for this population is much needed.

It is debatable whether adaptive riding (AR) in children with cerebral palsy (CP) improves postural control and gross motor development. The study aim was to explore the feasibility of an extensive assessment protocol for a randomized controlled trial of therapist-designed adaptive riding (TDAR) in children with CP, with the goals of assessing the effect on child outcomes and evaluating working mechanisms of sitting postural control. A pretest-posttest group design with 2 baseline measurements was used. Six children (1 girl, 5 boys; age range=6-12 years, median age=8 years 9 months) with bilateral spastic CP (Gross Motor Function Classification System level III) participated. Outcomes were evaluated 3 times (T0, T1, and T2) at 6-week intervals. T0 and T1 were baseline measurements; between T1 and T2, a TDAR intervention including an integrated program of postural challenge exercises (2 times per week for 1 hour) was applied. The complex protocol included the 88-item Gross Motor Function Measure (GMFM-88) and electromyographic (EMG) recording of postural muscle activity during reaching while sitting (EMG recording at T1 and T2 only). The protocol was feasible. Median GMFM-88 scores changed from 64.4 at T0 to 66.7 at T1 and from 66.7 at T1 to 73.2 at T2. The change scores for all children exceeded the minimal clinically important difference of the GMFM-88. Five of 6 children showed a decrease in stereotyped top-down recruitment between T1 and T2. Study limitations included the lack of a control group, small sample size, and potential assessor bias for all but the EMG parameters. The feasibility of the complex protocol was established. The data suggested that a 6-week TDAR intervention may improve gross motor function and may reduce stereotyped postural adjustments in children with CP. The limited results warrant replication in a well-powered randomized controlled trial. © 2015 American Physical Therapy Association.

Aims The Home or Hospital in Heart failure (HHH) study was a European Community-funded, multinational, randomized controlled clinical trial, conducted in the UK, Poland, and Italy, to assess the feasibility of a new system of home telemonitoring (HT). The HT system was used to monitor clinical and physiological parameters, and its effectiveness (compared with usual care) in reducing cardiac events in heart failure (HF) patients was evaluated. Measurements were patient-managed. Methods and results From 2002 to 2004, 461 HF patients (age 60 ± 11 years, New York Heart Association class 2.4 ± 0.6, left ventricular ejection fraction 29 ± 7%) were enrolled at 11 centres and randomized (1:2) to either usual outpatient care or HT administered as three randomized strategies: (i) monthly telephone contact; (ii) strategy 1 plus weekly transmission of vital signs; and (iii) strategy 2 plus monthly 24 h recording of cardiorespiratory activity. Patients completed 81% of vital signs transmissions, as well as 92% of cardiorespiratory recordings. Over a 12-month follow-up, there was no significant effect of HT in reducing bed-days occupancy for HF or cardiac death plus HF hospitalization. Post hoc analysis revealed a heterogeneous effect of HT in the three countries with a trend towards a reduction of events in Italy. Conclusion Home or Hospital in Heart failure indicates that self-managed HT of clinical and physiological parameters is feasible in HF patients, with surprisingly high compliance. Whether HT contributes to a reduction of cardiac events requires further investigation. PMID:19228800

Inefficient cognitive flexibility is considered a neurocognitive trait marker involved in the development and maintenance of anorexia nervosa (AN). Cognitive Remediation Therapy (CRT) is a specific treatment targeting this cognitive style. The aim of this study was to investigate the feasibility and efficacy (by estimating the effect size) of specifically tailored CRT for AN, compared to non-specific cognitive training. A prospective, randomized controlled, superiority pilot trial was conducted. Forty women with AN receiving treatment as usual (TAU) were randomized to receive either CRT or non-specific neurocognitive therapy (NNT) as an add-on. Both conditions comprised 30 sessions of computer-assisted (21 sessions) and face-to-face (9 sessions) training over a 3-week period. CRT focused specifically on cognitive flexibility. NNT was comprised of tasks designed to improve attention and memory. The primary outcome was performance on a neuropsychological post-treatment assessment of cognitive set-shifting. Data available from 25 treatment completers were analyzed. Participants in the CRT condition outperformed participants in the NNT condition in cognitive set-shifting at the end of the treatment (p = 0.027; between-groups effect size d = 0.62). Participants in both conditions showed high treatment acceptance. This study confirms the feasibility of CRT for AN, and provides a first estimate of the effect size that can be achieved using CRT for AN. Furthermore, the present findings corroborate that neurocognitive training for AN should be tailored to the specific cognitive inefficiencies of this patient group.

Accurate assessment of people’s preferences for different outdoor lighting applications is increasingly considered important in the development of new urban environments. Here a new method of random environmental walking is proposed to complement current methods of assessing urban lighting applications, such as self-report questionnaires. The procedure involves participants repeatedly walking between different lighting applications by random selection of a lighting application and preferred choice or by random selection of a lighting application alone. In this manner, participants are exposed to all lighting applications of interest more than once and participants’ preferences for the different lighting applications are reflected in the number of times they walk to each lighting application. On the basis of an initial simulation study, to explore the feasibility of this approach, a comprehensive field test was undertaken. The field test included random environmental walking and collection of participants’ subjective ratings of perceived pleasantness (PP), perceived quality, perceived strength, and perceived flicker of four lighting applications. The results indicate that random environmental walking can reveal participants’ preferences for different lighting applications that, in the present study, conformed to participants’ ratings of PP and perceived quality of the lighting applications. As a complement to subjectively stated environmental preferences, random environmental walking has the potential to expose behavioral preferences for different lighting applications. PMID:28337163

To examine the feasibility/acceptability of a parent-delivered Active Music Engagement (AME + P) intervention for young children with cancer and their parents. Secondary aim to explore changes in AME + P child emotional distress (facial affect) and parent emotional distress (mood; traumatic stress symptoms) relative to controls. A pilot two-group randomized trial was conducted with parents/children (ages 3-8 years) receiving AME + P ( n = 9) or attention control ( n = 7). Feasibility of parent delivery was assessed using a delivery checklist and child engagement; acceptability through parent interviews; preliminary outcomes at baseline, postintervention, 30 days postintervention. Parent delivery was feasible, as they successfully delivered AME activities, but interviews indicated parent delivery was not acceptable to parents. Emotional distress was lower for AME + P children, but parents derived no benefit. Despite child benefit, findings do not support parent delivery of AME + P. © The Author 2016.
