Abstract Background Immune-mediated hemolytic anemia (IMHA) is a common disease that affects all breeds of dogs and is associated with significant morbidity and mortality. Intravascular hemolysis of erythrocytes in IMHA is caused by complement activation and is often fatal. No current treatments target complement activation in canine IMHA. Human C1 esterase (C1-INH) reduces canine complement-mediated hemolysis in vitro, and a recent pharmacokinetic analysis of an FDA licensed formulation of C1-INH in dogs confirmed that a 50 IU/kg dose of C1-INH is safe to administer to dogs, and effectively inhibits canine complement mediated hemolysis ex-vivo. The C1INCH randomized controlled trial will evaluate the efficacy of this drug in dogs with intravascular hemolysis. Methods We will conduct a multicenter, placebo-controlled double-blind randomized clinical trial of C1-INH in dogs with intravascular hemolysis due to IMHA. We will randomize 18 dogs to receive three doses of intravenous C1-INH or saline in 24 h. Immunosuppressive and antithrombotic therapies will be standardized. Primary outcome measures will be changes in plasma free hemoglobin, serum concentrations of LDH, bilirubin, and haptoglobin. Using patient samples, we will evaluate complement activation in canine IMHA using a novel C5b-9 ELISA assay, flow cytometric detection of C3b on RBC, and by measurement of residual plasma complement activity. Secondary outcome measures will be survival to hospital discharge, duration of hospitalization, number and volume of red blood cell transfusions, and rescue therapy requirements. We will monitor dogs for adverse drug reactions. Sample size was estimated from pilot data on LDH and hemolysis index (HI) in dogs with IMHA. To detect 2-way differences between the upper and lower 50% of the LDH and HI values of equivalent size with 80% power at P < 0.05 will require 9 dogs in each arm. Discussion We anticipate that IV administration of C1-INH will significantly inhibit complement mediated hemolysis in dogs with intravascular IMHA, as determined by blood biomarker measurements (decreased plasma hemoglobin, LDH and bilirubin, increased haptoglobin). We expect this will translate into significant reductions in transfusion requirements and duration of hospitalization. Trial registration This trial has been prospectively registered with the AVMA registry (AAHSD005025).

OBJECTIVE The aim of this study was to access the influence of active warming after epidural anesthesia (EDA) and before general anesthesia in prevention of perioperative hypothermia. METHOD This randomized controlled trial was conducted in the department of anesthesiology in university medical center of Ho Chi Minh city, Vietnam from December 2019 until April 2020. This trial included 60 adult patients who were scheduled for major abdominal surgery with a duration of at least 120 minutes and under combined general anesthesia and EDA. Patients were excluded if age was below 18 years, American Society Anesthesiologists’ physical status classification of IV or higher, or refusal of EDA. Written informed consent was obtained for all patients. Patients were divided randomly into two groups. The first group received 10 minutes of active air-forced warming after EDA before the induction of general anesthesia. The second group was covered with a blanket 10 minutes after EDA and before general anesthesia. Core temperatures were recorded throughout the study. The primary outcome measures were the incidence of perioperative hypothermia and the degree of hypothermia. The secondary outcome measures were rate and time for body temperature to return to normal and incidence of postoperative body shivering. RESULTS Without active warming (n = 21), 70% of patients became hypothermic (<36°C) postoperatively. Active air-forced warming for 10 minutes after EDA and before induction of general anesthesia decreased the incidence of postoperative hypothermia to 26.7% (n = 8). CONCLUSION Active air-forced warming for 10 minutes after EDA and before induction of general anesthesia is efficient in reducing the incidence of perioperative hypothermia.

Blended Care

BACKGROUND Support programs for partners of patients with acquired brain injury are necessary since these partners experience several unfavorable consequences of caregiving, such as a high burden, emotional distress, and poor quality of life. Evidence-based support strategies that can be included in these support programs are psychoeducation, skill building, problem solving, and improving feelings of mastery. A promising approach would seem to be to combine web-based support with face-to-face consultations, creating a blended care intervention. OBJECTIVE This paper outlines the protocol of a randomized controlled trial to evaluate the CARE4Carer blended care intervention for partners of patients with acquired brain injury. METHODS A multicenter two-arm randomized controlled trial will be conducted. A total of 120 partners of patients with acquired brain injury will be recruited from five rehabilitation centers in the Netherlands. The blended care intervention consists of a nine-session web-based support program and two face-to-face consultations with a social worker. Themes that will be addressed are: giving partners insight into their own situation, including possible pitfalls and strengths, learning how to cope with the situation, getting a grip on thoughts and feelings, finding a better balance in the care for the patient with acquired brain injury, thinking about other possible care options, taking care of oneself, and communication. The intervention lasts 20 weeks and the control group will receive usual care. The outcome measures will be assessed at baseline and at 24- and 40-week follow-up. The primary outcome is caregiver mastery. Secondary outcome measures are strain, burden, family functioning, emotional functioning, coping, quality of life, participation, and social network. RESULTS The effect of the intervention on the primary and secondary outcome measures will be determined. Additional a process evaluation will be conducted. CONCLUSIONS The findings of this study will be used to improve the care for partners of patients with acquired brain injury. Barriers and facilitators that emerge from the process evaluation will be used in the nationwide implementation of the intervention.

Abstract Background Sleep deficiency affects a majority of pregnant women with significant impact on daily function, mood, and pregnancy and birth outcomes. This ongoing study combines two evidence-based strategies for improving sleep and mood, mindfulness meditation and cognitive-behavioral therapy for insomnia (CBT-I), in a unique online format to address the particular needs of pregnant women. The purpose of this study is to test the feasibility and estimate the efficacy of this novel 6-week online mindfulness meditation intervention to help pregnant women in remission from depression self-manage insomnia. Methods This is a two-arm, parallel group randomized controlled trial. A total of 50 pregnant women between 12 and 28 weeks gestation will be recruited from the community and randomly assigned to a mindfulness or education-only control group in a 1:1 ratio. During the study, all participants will complete six weekly online modules, daily sleep diaries, and optional participation in a treatment-specific online discussion forum. Feasibility outcome measures will include study recruitment, retention, intervention adherence (number of online modules completed, number of meditation days per week), and intervention acceptability (8-item questionnaire). The primary clinical outcome measure will be sleep quality measured with the Pittsburgh Sleep Quality Index. Secondary outcome measures will include sleep measured with actigraphy and diaries (sleep efficiency, total sleep time, total wake time), Patient-Reported Outcomes Measurement Information System (PROMIS) measures (fatigue, sleep-related impairment, sleep disturbance); mood (depression, anxiety, positive affect, quality of life); and self-management and behavior change (potential self-efficacy, self-regulation, sleep problem acceptance, and trait mindfulness). Assessments will occur at baseline and post-intervention; an additional acceptability survey will be completed 4 weeks postpartum. Analyses will examine within-group differences in outcome change scores from baseline to post-intervention. Open-ended feedback will be analyzed using qualitative content analysis. Discussion This research is innovative in addressing sleep in pregnancy using a self-management research design and methods that can be accessible and cost-effective for large numbers of pregnant women. The results from this study will inform intervention refinement and efficacy testing of the intervention in a larger randomized controlled trial. Trial registration ClinicalTrials.gov, NCT04016428.

Background: Whereas hearing aids have long been considered effective for providing relief from tinnitus, controlled clinical studies evaluating this premise have been very limited. Purpose: The purpose of this study was to systematically determine the relative efficacy of conventional receiver-in-the-canal hearing aids (HA), the same hearing aids with a sound generator (HA+SG), and extended-wear, deep fit hearing aids (EWHA), to provide relief from tinnitus through a randomized controlled trial. Each of these ear-level devices was a product of Phonak, LLC. Research Design: Participants were randomized to HA, HA+SG, or EWHA and wore bilaterally fit devices for about 4 months. Fittings, adjustments, and follow-up appointments were conducted to comply with company guidelines and to ensure that all participants attended appointments on the same schedule. At 4–5 months, participants returned to complete final outcome measures, which concluded their study participation. Study Sample: Participants were 55 individuals (mean age: 63.1 years) with mild to moderately-severe hearing loss who: (a) did not currently use hearing aids; (b) reported tinnitus that was sufficiently bothersome to warrant intervention; and (c) were suitable candidates for each of the study devices. Data Collection and Analysis: The primary outcome measure was the Tinnitus Functional Index (TFI). Secondary outcome measures included hearing-specific questionnaires and the Quick Speech in Noise test (QuickSIN). The goal of the analysis was to evaluate efficacy of the EWHA and HA+SG devices versus the HA standard device. Results: There were 18 participants in each of the HA and EWHA groups and 19 in the HA+SG group. Gender, age, and baseline TFI severity were balanced across treatment groups. Nearly all participants had a reduction in tinnitus symptoms during the study. The average TFI change (improvement) from baseline was 21 points in the HA group, 31 points in the EWHA group, and 33 points in the HA+SG group. A “clinically significant” improvement in reaction to tinnitus (at least 13-point reduction in TFI score) was seen by 67% of HA, 82% of EWHA, and 79% of HA+SG participants. There were no statistically significant differences in the extent to which the devices reduced TFI scores. Likewise, the hearing-specific questionnaires and QuickSIN showed improvements following use of the hearing aids but these improvements did not differ across device groups. Conclusions: There is insufficient evidence to conclude that any of these devices offers greater relief from tinnitus than any other one tested. However, all devices appear to offer some improvement in the functional effects of tinnitus.

Abstract Background: Dysmenorrhea seriously affects the ability to perform normal social activities and decreases quality of life. Primary dysmenorrhea can be effectively treated with acupuncture. Based on the wrist-ankle acupuncture (WAA) theory, we designed a portable WAA point compression treatment strap that treats diseases by automatically applying pressure to acupuncture points. The proposed study aims to evaluate the analgesic effect of the acupressure wrist-ankle strap in patients with primary dysmenorrhea. Methods: The study will be a randomized controlled trial conducted from 1 May 2019 30 May 2020 that includes 78 students from Shanghai University of Traditional Chinese Medicine who have primary dysmenorrhea and meet the eligibility criteria. Participants will be randomly divided into two groups in a 1:1 allocation ratio. The intervention group will use the acupressure wrist-ankle strap equipped with tip compression component parts on the internal side; the control group will use the non-acupressure wrist-ankle strap with the tip compression parts removed. All participants will be treated for 30 min on the first day of menstruation. The main outcome measures are the pain intensity score measured by the visual analogue scale, and the onset time of analgesia. The secondary outcome measures are the pain threshold at Yinlingquan (SP 9) , skin temperature at Guanyuan (CV 4) , and expectations and satisfaction of patients as investigated via the Expectation and Treatment Credibility Scale. Discussion: This trial will be the first study to evaluate the analgesic effect of the acupressure wrist-ankle strap in patients with primary dysmenorrhea. The quality of this study is ensured by the strict randomization, non-acupressure control, and blinded design. The results may provide a potential alternative treatment for primary dysmenorrhea and evidence-based proof of the analgesic effect of WAA.

Abstract Background Violence has severe and long-lasting negative consequences for children’s and adolescents’ well-being and psychosocial functioning, thereby also hampering communities’ and societies’ economic growth. Positive attitudes towards violence and the lack of access to alternative non-violent strategies are likely to contribute to the high levels of teachers’ ongoing use of violence against children in sub-Saharan African countries. Notwithstanding, there are currently very few school-level interventions to reduce violence by teachers that a) have been scientifically evaluated and b) that focus both on changing attitudes towards violence and on equipping teachers with non-violent discipline strategies. Thus, the present study tests the effectiveness of the preventative intervention Interaction Competencies with Children – for Teachers (ICC-T) in primary and secondary schools in Tanzania, Uganda, and Ghana. Methods The study is a multi-site cluster randomized controlled trial with schools (clusters) as level of randomization and three data assessment points: baseline assessment prior to the intervention, the first follow-up assessment 6 months after the intervention and the second follow-up assessment 18 months after the intervention. Multi-stage random sampling will be applied to select a total number of 72 schools (24 per country). Schools will be randomly allocated to the intervention and the control condition after baseline. At each school, 40 students (stratified by gender) in the third year of primary school or in the first year of secondary/junior high school and all teachers (expected average number: 20) will be recruited. Thus, the final sample will comprise 2880 students and at least 1440 teachers. Data will be collected using structured clinical interviews. Primary outcome measures are student- and teacher-reported physical and emotional violence by teachers in the past week. Secondary outcome measures include children’s emotional and behavioral problems, quality of life, cognitive functioning, academic performance, school attendance and social competence. Data will be analyzed using multilevel analyses. Discussion This study aims to provide further evidence for the effectiveness of ICC-T to reduce teacher violence and to improve children’s functioning (i.e., mental health, well-being, academic performance) across educational settings, societies and cultures.

Background: A small number of randomized controlled trials have found ultrasound-guided injection of platelet-rich plasma (PRP) to be no more effective than saline for several tendinopathies; limited information exists for patellar tendinopathy. In addition, different PRP formulations that produce varying concentrations of leukocytes have not been directly compared for patellar tendinopathy. Purpose/Hypothesis: To determine if a single ultrasound-guided PRP injection, either leukocyte-rich PRP (LR-PRP) or leukocyte-poor PRP (LP-PRP), was superior to saline injection for the treatment of patellar tendinopathy. The null hypothesis was that no treatment would be superior to another for the treatment of patellar tendinopathy. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Athletes with patellar tendinopathy for ≥6 months (Blazina stage IIIB) were assessed for eligibility in a multisite single-blind controlled trial. There were 3 injection arms: LR-PRP, LP-PRP, and saline. Patients received a single ultrasound-guided injection, followed by 6 weeks of supervised rehabilitation (heavy slow resistance training, concentric and eccentric, 3 times per week). Outcome measures—Victorian Institute of Sport Assessment (patellar; VISA-P), pain during activity, and global rating of change—were assessed at 6 and 12 weeks and 6 and 12 months. VISA-P score at 12 weeks was the primary outcome. Fifty-seven patients (19 in each group) were included in an intention-to-treat analysis. Secondary outcome measures included pain during activity and patients’ global rating of change. Results: Study retention was 93% at 12 weeks and 79% after 1 year. There was no significant difference in mean change in VISA-P score, pain, or global rating of change among the 3 treatment groups at 12 weeks or any other time point. After 1 year, the mean (SD) outcomes for the LR-PRP, LP-PRP, and saline groups were as follows, respectively: VISA-P—58 (29), 71 (20), and 80 (18); pain—4.0 (2.4), 2.4 (2.3), and 2.0 (1.9); global rating of change—4.7 (1.6), 5.6 (1.0), and 5.7 (1.2) ( P > .05 for all outcomes). Conclusion: Combined with an exercise-based rehabilitation program, a single injection of LR-PRP or LP-PRP was no more effective than saline for the improvement of patellar tendinopathy symptoms.

Spasticity is one of the main complications of a stroke. This double-blind, randomized controlled trial aimed to compare the result of three sessions of dry needling (DN) versus sham DN on the affected upper limbs in post-stroke survivors. We recruited 24 patients (age 57.0 ± 9.6 years; male 71%). Patients were randomly allocated to two groups: a DN group and a sham DN group. The primary outcome measures were the Modified Modified Ashworth Scale (MMAS) and the Box and Block Test (BBT). Secondary outcome measures included active and passive wrist range of motion (AROM and PROM). All assessments were measured at baseline, immediately after the last session of the intervention, and one month later. Patients in the DN group had improved upper limb spasticity and passive wrist range of motion compared to control group (P < 0.05). There were no between-group differences in other outcome measures (P > 0.05). Dry needling is a useful method for improving muscle spasticity in the upper limbs of patients with stroke.

Background. Asthma continues to be a substantial cause of morbidity in pediatric populations. New strategies are needed to provide cost-effective educational interventions for children with asthma, particularly those in the inner city. Objective. To assess the effectiveness of a multimedia educational software program about asthma. Setting. A hospital-based primary care clinic and an affiliated neighborhood health center. Design. Randomized, controlled trial. Population. Children 3 to 12 years old with physician-diagnosed asthma. Intervention. An interactive educational computer program, Asthma Control, designed to teach children about asthma and its management. Using a graphic display of a child going through simulated daily events, the game emphasizes: 1) monitoring; 2) allergen identification; 3) use of medications; 4) use of health services; and 5) maintenance of normal activity. Control group participants reviewed printed educational materials with a research assistant. Outcomes. Acute health care use (emergency department and outpatient) was the primary outcome. Secondary outcome measures included maternal report of asthma symptom severity, child functional status and school absences, satisfaction with care, and parental and child knowledge of asthma. Results. A total of 137 families were enrolled in the study (76 intervention, 61 control). Both intervention and control groups showed substantial improvement in all outcomes during the 12-month follow-up period. Aside from improvement in knowledge after use of the computer program, no differences were demonstrated between the 2 groups in primary or secondary outcome measures. Children reported enjoyment of program use. Conclusions. This trial of an educational software program found that it did not produce greater improvement than occurred with review of traditional written materials. Because both groups showed substantial improvement over baseline, computer-based education may be more cost-effective. Alternatively, improvements in illness severity over time may overshadow the effects of such interventions. Rigorous comprehensive evaluations such as this are necessary to assess new interventions intended to improve management and outcomes of asthma.

Abstract Background Tobacco smoking remains one of the biggest public health threats. Smartphone apps offer new promising opportunities for supporting smoking cessation in real-time. The social context of smokers has, however, been neglected in smartphone apps promoting smoking cessation. This randomized controlled trial investigates the effectiveness of a smartphone app in which smokers quit smoking with the help of a social network member. Methods This protocol describes the design of a single-blind, two-arm, parallel-group, intensive longitudinal randomized controlled trial. Participants of this study are adult smokers who smoke at least one cigarette per day and intend to quit smoking at a self-set quit date. Blocking as means of group-balanced randomization is used to allocate participants to intervention or control conditions. Both intervention and control group use a smartphone-compatible device for measuring their daily smoking behavior objectively via exhaled carbon monoxide. In addition, the intervention group is instructed to use the SmokeFree Buddy app, a multicomponent app that also facilitates smoking-cessation specific social support from a buddy over a smartphone application. All participants fill out a baseline diary for three consecutive days and are invited to the lab for a background assessment. They subsequently participate in an end-of-day diary phase from 7 days before and until 20 days after a self-set quit date. Six months after the self-set quit date a follow-up diary for three consecutive days takes place. The primary outcome measures are daily self-reported and objectively-assessed smoking abstinence and secondary outcome measures are daily self-reported number of cigarettes smoked. Discussion This is the first study examining the effectiveness of a smoking cessation mobile intervention using the SmokeFree Buddy app compared to a control group in a real-life setting around a self-set quit date using a portable objective measure to assess smoking abstinence. Opportunities and challenges with running studies with smoking participants and certain design-related decisions are discussed. Trial registration This trial was prospectively registered on 04/04/2018 at ISRCTNregistry: ISRCTN11154315.
