Peripheral warming for prevention of hypothermia in small dogs during soft tissue surgery: A randomized controlled trial

OBJECTIVE

To evaluate the effects of wrapping the extremities of small dogs with table leg covers to prevent hypothermia during anesthesia.

STUDY DESIGN

Randomized parallel-group study.

ANIMALS

A total of 60 adult dogs with a body mass <15 kg anesthetized for soft tissue surgery.

METHODS

Dogs were randomly assigned to one of two groups. The control group received routine intraoperative thermal support, while the limb-wrapping group had their peripheral limbs covered with table leg covers up to the mid-metacarpal/metatarsal region, in addition to routine thermal support. Rectal temperature during anesthesia was recorded and compared between the two groups. Data analyses were performed using Student's t-test for rectal temperature, Fisher's exact test for hypothermia incidence and analysis of covariance for the effect of limb-wrapping while taking other factors into account.

RESULTS

Thirty dogs were included per group. Rectal temperature did not differ between the groups at the time of intubation, but it was significantly higher in the limb-wrapping group (36.7 ± 1.0 °C) than in the control group (35.9 ± 0.8 °C) at the end of surgery (p = 0.003). The mean difference was 0.81 °C (95% confidence interval of mean difference 0.33-1.29 °C). The incidence of hypothermia (<37.0 °C) was significantly lower in the limb-wrapping group than in the control group (19/30 versus 28/30 dogs, respectively; p = 0.010).

CONCLUSIONS

For dogs with body masses <15 kg, limb-wrapping with table leg covers slowed the reduction in intraoperative rectal temperature. Limb-wrapping is inexpensive and easy to perform, making it a practical method for minimizing hypothermia during anesthesia in small dogs undergoing soft tissue surgery.

CLINICAL RELEVANCE

Peripheral warming with table leg covers has the potential to reduce hypothermia during soft tissue surgery in small dogs.

Effects of insoles adapted in flip-flop sandals in patients with persistent plantar heel pain: A sham-controlled randomised trial

OBJECTIVE

To evaluate the use of custom-made insoles adapted to flip-flops on pain intensity, foot function, and functional walking ability in individuals with persistent plantar heel pain in the short and medium term.

DESIGN

Randomised controlled trial.

SETTING

Flip-flop sandals in patients with persistent plantar heel pain.

MAIN MEASURES

Participants (n = 80) were assessed at baseline, six and 12 weeks after the intervention, and 4 weeks post-intervention.

RESULTS

For the primary outcomes, after 6 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.4 (95% confidence intervals = -1.5 to 0.8). Similarly, after 12 weeks of intervention, no between-group difference was observed in the intensity of morning pain or pain with walking, mean difference = -0.7 (95% confidence intervals = -1.9 to 0.6). Finally, at 4 weeks after the end of the intervention, there was no between-group difference in morning pain or pain on walking, mean difference = 0.01 (95% confidence intervals = -1.4 to 1.4). All differences and confidence intervals were smaller than the minimum clinically important difference for pain (2 points). There were no differences between the groups for the secondary outcomes. In addition, the mean differences were smaller than the minimum clinically important differences for pain intensity, foot function and functional walking ability.

CONCLUSION

Custom-made insoles fitted to flip-flops did not differ from flip-flops with sham insoles in improving pain intensity, foot function and functional walking ability in people with persistent heel pain.Trial registration: ClinicalTrials.gov (Identifier: NCT04784598).

Does music training improve inhibition control in children? A systematic review and meta-analysis

Inhibition control is an essential executive function during children's development, underpinning self-regulation and the acquisition of social and language abilities. This executive function is intensely engaged in music training while learning an instrument, a complex multisensory task requiring monitoring motor performance and auditory stream prioritization. This novel meta-analysis examined music-based training on inhibition control in children. Records from 1980 to 2023 yielded 22 longitudinal studies with controls (N = 1734), including 8 RCTs and 14 others. A random-effects meta-analysis showed that music training improved inhibition control (moderate-to-large effect size) in the RCTs and the superset of twenty-two longitudinal studies (small-to-moderate effect size). Music training plays a privileged role compared to other activities (sports, visual arts, drama) in improving children's executive functioning, with a particular effect on inhibition control. We recommend music training for complementing education and as a clinical tool focusing on inhibition control remediation (e.g., in autism and ADHD).

Comparison of different telerehabilitation protocols for urogenital symptoms in females with multiple sclerosis: a randomized controlled trial

Telerehabilitation has been suggested to be equally effective than in-person rehabilitation, and could be helpful to increase participation and reduce barriers. People with multiple sclerosis (MS) often present urogenital dysfunctions, impairing independence and quality of life (QoL). Since the different available telerehabilitation protocols, the present study aimed to compare a live video urogenital rehabilitation intervention protocol (REMOTE) with a home-based pre-recorded video protocol (SELF). A randomized-controlled trial was performed, with 14 females with MS being allocated in the REMOTE group (36 ± 9 y) and 14 females in the SELF group (37 ± 7 y). Both telerehabilitation protocols were identical in terms of contents (including pelvic floor training and relaxation exercises), frequency and duration, consisting of 10 sessions of 45 min each, every 5 days. Questionnaires were administered at the beginning and the end of the study: Short Form Health Survey 36 (SF-36), Beck Depression Inventory (BDI), Female Sexual Function Index (FSFI), International Consultation on Incontinence Questionnaire (ICIQ) symptoms and related QoL, the main outcome being ICIQ incontinence score. Despite most of the outcomes improved in both groups, REMOTE was found to be more effective than SELF in most of the SF-36 domains (from p < 0.001 pη2 0.555 to p = 0.044 pη2 0.147), FSFI (p = 0.001 pη2 0.373), ICIQ (p = 0.003 pη2 0.291). Despite the home-based pre-recorded videos could be effective in improving urogenital symptoms, live video urogenital rehabilitation results in larger improvements. Telerehabilitation should be encouraged for urogenital dysfunctions in females with MS, and pre-recorded videos could represent an alternative when live sessions are not available. Clinical trial registration This randomized controlled trial was registered on ClinicalTrials.gov with the number NCT05984095.

A systematic literature review of the measurement of patient-reported fatigue in studies of disease modifying therapies for multiple sclerosis

BACKGROUND

Fatigue is the most commonly experienced symptom among people with multiple sclerosis (MS) and has the greatest impact in reducing quality of life. It is important to measure change in MS-related fatigue (MS-fatigue) in response to treatment, particularly the more recent disease modifying therapies (DMTs). To date there has been no systematic literature review of the patient reported outcome (PRO) tools used to measure MS- fatigue specifically in the context of DMTs.

METHODS

MEDLINE, Embase and Clinicaltrials.gov were searched from 01 January 2000 to 13 April 2021 to identify published studies of the treatment of MS with DMTs. Studies where MS-fatigue was measured as an outcome using a PRO tool were included in the review. Further literature searches were undertaken to provide information about the development and validation of each PRO tool.

RESULTS

739 abstracts and 96 clinical trials were manually screened resulting in 68 articles for full text screening. 48 studies were identified for the review; 10 of these were RCTs that considered MS-fatigue as a secondary outcome (4 were Phase 3 trials). The PRO instruments used in the 10 RCTs were the Fatigue Scale for Motor and Cognitive Functions, Fatigue Impact Scale, Modified Fatigue Impact Scale, Fatigue Severity Scale, and Fatigue Symptoms and Impacts Questionnaire - Relapsing Multiple Sclerosis. The other 38 studies were all open-label, longitudinal, non-randomized studies and used the following PRO instruments in addition to those listed above: the Visual Analogue Scale for Fatigue, the Fatigue Descriptive Scale, Modified Fatigue Impact Scale (5 items) and the Würzburger Fatigue Inventory for MS. All these PRO tools were specifically developed for MS-fatigue. Of these 9 PRO tools, 7 were of good methodological quality according to the existing validation studies using the Consensus-based standards for the selection of health measurement instruments (COSMIN) check list and were used in the majority of the MS DMT studies (44/48, 92%). The median follow-up time from baseline to PRO measurement was 12 months (range 1-36 months). Most studies reported on MS fatigue in terms of its change from baseline and whether the change was statistically significant. 5 studies also reported what they considered to be a clinically meaningful difference.

CONCLUSIONS

Although fatigue has the greatest impact on quality of life in people with MS, few studies have rigorously investigated the impact of DMTs on fatigue. Comparisons between study outcomes using different PRO tools is challenging due to the variety of psychometric constructs addressed by the questionnaires and differences in the recall period for fatigue symptoms and the measurement scale. Furthermore most of the PRO tools used to quantify MS-fatigue in studies of DMTs are descended from PRO tools developed during the 1990s before DMTs emerged and before widespread patient involvement in PRO development. New PRO tools should involve patients in their development as recommended by the US Food and Drug Administration and the validation process should consider the sensitivity of the PRO tool to change in fatigue over time or between groups.

A randomised controlled trial of the effect of intra-articular lidocaine on pain scores in inflammatory arthritis

ABSTRACT

Chronic pain in inflammatory arthritis (IA) reflects a complex interplay between active disease in a peripheral joint and central pronociceptive mechanisms. Because intra-articular lidocaine may be used to abolish joint-specific peripheral input to the central nervous system, we aimed to validate its use as a clinical tool to identify those patients with IA whose pain likely incorporates centrally mediated mechanisms. We began by investigating whether there was a placebo response of intra-articular injection in patients with IA 1:1 randomised to receive intra-articular lidocaine or control (0.9% saline). After, in a larger patient cohort not randomized to placebo vs lidocaine groups, we tested whether patients with IA could be stratified into 2 cohorts based on their response to intra-articular lidocaine according to markers of centrally mediated pain. To this end, we evaluated postlidocaine pain numerical rating scale (NRS) scores alongside baseline painDETECT, fibromyalgia criteria fulfillment, and quantitative sensory testing outcomes. Numerical rating scale scores were collected at baseline and 3-, 5-, and 10-minutes postinjection. Firstly, the placebo effect of intra-articular injection was low: compared to baseline, the mean pain NRS score 5-minutes postinjection was reduced by 3.5 points in the lidocaine group vs 1.2 points in the control group. Secondly, postlidocaine NRS scores were significantly higher in those with a high (>18) baseline painDETECT score, fibromyalgia, and low-pressure pain threshold at the trapezius ( P = 0.002, P = 0.001, P = 0.005, respectively). Persistent high pain after intra-articular lidocaine injection could be used as an indicator of pronociceptive mechanisms that are centrally mediated, informing centrally targeted analgesic strategies.

Serious adverse events reporting in recent randomised clinical trials in intensive care medicine - A methodological study protocol

BACKGROUND

Serious adverse events (SAEs) are common in intensive care unit (ICU) patients. Reporting of SAEs in randomised clinical trials (RCTs) varies why underreporting is likely. We aim to describe the reporting of SAEs from 2020 onwards and to illustrate the recent reporting of SAEs published in major medical journals.

METHODS

We will conduct a methodological study assessing pharmacological interventions in RCTs including adult ICU patients. We will search 10 general medical and critical care journals in PubMed. We will include all RCTs published from 2020 onwards. The primary research question is how many RCTs report SAEs in the primary publication. Secondary research questions include how SAEs are reported in the primary publication either as (1) proportion of patients experiencing one or more SAE, (2) all single events occurred, or (3) both strategies combined. We will assess the association between the proportion of patients with reported SAEs and the following trial characteristics: multicentred versus single-centre RCTs, industry-sponsored versus academic-sponsored, published trial protocol versus unpublished work, blinding, trials sample size, and RCTs focusing on COVID-19 patients versus other populations.

DISCUSSION

The outlined methodological study will provide important information on the reporting of SAEs in recent drug trials in adult ICU patients.

Effect of using gamification and augmented reality in mechanical ventilation unit of critical care nursing on nurse students' knowledge, motivation, and self-efficacy: A randomized controlled trial

BACKGROUND

Gamification and augmented reality (AR) are innovative teaching modalities. Research on the effects of combining these two strategies in nursing education is scarce.

OBJECTIVES

To examine the effect of the combined use of gamification and AR in teaching mechanical ventilation (MV) on nurse students' knowledge, motivation, self-efficacy, and satisfaction.

DESIGN

Randomized controlled trial.

SETTING

A conveniently selected faculty of nursing in Egypt.

PARTICIPANTS

A total of 410 nurse students.

METHODS

Participants were randomly assigned to the intervention or control group (205 in each). Kahoot games and AR were used in the intervention group, whereas a traditional lecture was applied in the control group. The outcomes included levels of students' knowledge, learning motivation, self-efficacy, and satisfaction.

RESULTS

Mixed design repeated-measures ANOVA test revealed a statistically significant difference in knowledge test scores within-subject over time (p-value [effect size]: <0.001 [0.515]), between-subject due to the main effect of interventions (<0.001 [0.146]), and within-between interaction effect of group and time (<0.001 [0.515]). After using Kahoot and AR, the total mean self-efficacy score was significantly higher in the intervention group than in the control group (<0.001 [0.662]). The total median motivation score was significantly higher for the Kahoot and the AR groups compared with the traditional lecture (<0.001 [0.558]).

CONCLUSION

Kahoot games and AR significantly increased nurse students' knowledge, motivation, and self-efficacy compared with traditional MV learning classes. Nursing educators need to incorporate Kahoot and AR in their pedagogies to enhance nurse students' satisfaction and development.

Development of a core domain set for ankle osteoarthritis: An international consensus study of patients and health professionals

OBJECTIVES

To develop an internationally agreed-upon core domain set for ankle osteoarthritis (OA).

METHODS

In a three-part Delphi process, a group of multidisciplinary health professionals with expertise in ankle OA and people with ankle OA responded to online questionnaires. The questionnaires proposed a list of 29 candidate domains derived from a systematic review of ankle OA research, and interviews with people with ankle OA and health professionals. Consensus was defined a priori as ≥70% agreement in people with ankle OA and health professionals whether a domain should or should not be included in a core domain set. An online consensus meeting was held to discuss and resolve undecided candidate domains.

RESULTS

A total of 100 people (75 health professionals and 25 people with ankle OA) from 18 countries (4 continents) participated in this study. Five domains reached consensus for inclusion in a core domain set for ankle OA - pain severity, health-related quality of life, function, disability and ankle range of motion. Twenty-one candidate domains reached agreement not to be included in the core domain set, and three domains remained undecided (ankle instability, physical capacity, and mental health).

CONCLUSION

This international consensus study, which included people with ankle OA and health professionals, has established a core domain set for ankle OA with five domains that should be measured and reported in all ankle OA trials - pain severity, health-related quality of life, function, disability and ankle range of motion. This core domain set will guide the reporting of outcomes in clinical trials on ankle OA. Future research should determine which outcome measurement instruments should be used to measure each of the core domains.

Interpretation of statistical findings in randomised trials: a survey of statisticians using thematic analysis of open-ended questions

BACKGROUND

Dichotomisation of statistical significance, rather than interpretation of effect sizes supported by confidence intervals, is a long-standing problem.

METHODS

We distributed an online survey to clinical trial statisticians across the UK, Australia and Canada asking about their experiences, perspectives and practices with respect to interpretation of statistical findings from randomised trials. We report a descriptive analysis of the closed-ended questions and a thematic analysis of the open-ended questions.

RESULTS

We obtained 101 responses across a broad range of career stages (24% professors; 51% senior lecturers; 22% junior statisticians) and areas of work (28% early phase trials; 44% drug trials; 38% health service trials). The majority (93%) believed that statistical findings should be interpreted by considering (minimal) clinical importance of treatment effects, but many (61%) said quantifying clinically important effect sizes was difficult, and fewer (54%) followed this approach in practice. Thematic analysis identified several barriers to forming a consensus on the statistical interpretation of the study findings, including: the dynamics within teams, lack of knowledge or difficulties in communicating that knowledge, as well as external pressures. External pressures included the pressure to publish definitive findings and statistical review which can sometimes be unhelpful but can at times be a saving grace. However, the concept of the minimally important difference was identified as a particularly poorly defined, even nebulous, construct which lies at the heart of much disagreement and confusion in the field.

CONCLUSION

The majority of participating statisticians believed that it is important to interpret statistical findings based on the clinically important effect size, but report this is difficult to operationalise. Reaching a consensus on the interpretation of a study is a social process involving disparate members of the research team along with editors and reviewers, as well as patients who likely have a role in the elicitation of minimally important differences.

Early In-Bed Cycle Ergometry With Critically Ill, Mechanically Ventilated Patients: Statistical Analysis Plan for CYCLE (Critical Care Cycling to Improve Lower Extremity Strength), an International, Multicenter, Randomized Clinical Trial

BACKGROUND

Survivors of critical illness are at risk of developing physical dysfunction following intensive care unit (ICU) discharge. ICU-based rehabilitation interventions, such as early in-bed cycle ergometry, may improve patients' short-term physical function.

OBJECTIVE

Before unblinding and trial database lock, we describe a prespecified statistical analysis plan (SAP) for the CYCLE (Critical Care Cycling to Improve Lower Extremity Strength) randomized controlled trial (RCT).

METHODS

CYCLE is a 360-patient, international, multicenter, open-label, parallel-group RCT (1:1 ratio) with blinded primary outcome assessment at 3 days post-ICU discharge. The principal investigator and statisticians of CYCLE prepared this SAP with approval from the steering committee and coinvestigators. The SAP defines the primary and secondary outcomes (including adverse events) and describes the planned primary, secondary, and subgroup analyses. The primary outcome of the CYCLE trial is the Physical Function Intensive Care Unit Test-scored (PFIT-s) at 3 days post-ICU discharge. The PFIT-s is a reliable and valid performance-based measure. We plan to use a frequentist statistical framework for all analyses. We will conduct a linear regression to evaluate the primary outcome, incorporating randomization as an independent variable and adjusting for age (≥65 years versus <65 years) and center. The regression results will be reported as mean differences in PFIT-s scores with corresponding 95% CIs and P values. We consider a 1-point difference in PFIT-s score to be clinically important. Additionally, we plan to conduct 3 subgroup analyses: age (≥65 years versus <65 years), frailty (Baseline Clinical Frailty Scale ≥5 versus <5), and sex (male versus female).

RESULTS

CYCLE was funded in 2017, and enrollment was completed in May 2023. Data analyses are complete, and the first results were submitted for publication in 2024.

CONCLUSIONS

We developed and present an SAP for the CYCLE RCT and will adhere to it for all analyses. This study will add to the growing body of evidence evaluating the efficacy and safety of ICU-based rehabilitation interventions.

Effect of Mindfulness Training on Skill Performance in Simulator-Based Knee Arthroscopy Training for Novice Residents-A Randomized Controlled Study

OBJECTIVES

Negative emotions affect not only the physical health of residents but also the performance of surgical skills. Mindfulness training has been shown to be effective in improving mood. However, few studies have explored its effect on surgical skill performance. We aimed to investigate the effect of mindfulness training on knee arthroscopy skill performance.

DESIGN

We recruited 30 participants for knee arthroscopy skills training (Tasks 1-7) on a simulator, after which a pretest (Tasks 8 and 9) was conducted to test their skill performance and psychological states (including mindfulness state, anxiety, stress, and depression). Then, they were randomly assigned into 2 groups: the intervention group underwent 2 weeks of mindfulness training while the control group received no intervention. All participants were asked to retrain their skills 1 week after completing the initial arthroscopy skill training. After the 2-week mindfulness training intervention, a post-test was performed to detect the difference in skill performance and psychological states between 2 groups. We used the fNIRS device to record prefrontal cortex activation during the post-test.

SETTING

The study was carried out at the Zhujiang Hospital of Southern Medical University.

PARTICIPANTS

30 novice orthopedic residents.

RESULTS

A total of 30 residents completed all the study programs. We did not observe differences in arthroscopy skill performance at pretest. Compared with the control group, the intervention group showed significant improvement in total score of Task 8 (p = 0.034) and 9 (p = 0.002), as well as significant relief in anxiety (p = 0.037) and stress (p = 0.027) symptoms but no improvement in depression (p = 0.828). No statistical difference in 2 groups was observed on the activation of the left prefrontal cortex (p = 0.68).

CONCLUSIONS

Two weeks of mindfulness training can improve arthroscopy skill performance while alleviating anxiety and reducing stress in novice residents. Mindfulness training may be an effective adjunct to surgical skill training.

Managing the parasitic honey bee mite Tropilaelaps mercedesae through combined cultural and chemical control methods

The western honey bee (Apis mellifera) is severely impacted by the parasitic Tropilaelaps mercedesae mite, which has the capacity to outcompete Varroa destructor mites (the current leading cause of colony losses) and more rapidly overwhelm colonies. While T. mercedesae is native to Asia, it has recently expanded its geographic range and has the potential to devastate beekeeping worldwide if introduced to new regions. Our research exploited the dependence of T. mercedesae on developing honey bees (brood) by combining a cultural technique (brood break) with U.S. registered chemical products (oxalic acid or formic acid) to manage T. mercedesae infestation. To evaluate this approach, we compared four treatment groups: (1) Brood Break; (2) Brood Break + Formic Acid (FormicPro®); (3) Brood Break + Oxalic Acid dribble (Api-Bioxal®); and (4) untreated Control. We found that the mite infestation rate of worker brood in Control colonies rose from 0.4 to 15.25% over 60 days, whereas all other treatment groups had infestation rates under 0.11% on Day 60. Mite fall assessments showed similar results, whereby Control colonies had 15.48 mites fall per 24 h on day 60 compared to less than 0.2 mites for any other treatment group. Evaluation of colony strength revealed that Brood Break + Formic Acid colonies had slightly reduced adult honey bee populations. No treatment eliminated all mites, so additional measures may be needed to eradicate T. mercedesae if detected in countries that do not currently have T. mercedesae.

Comparison of statistical methods for the analysis of patient-reported outcomes in randomised controlled trials: A simulation study

Patient-reported outcomes (PROs) that aim to measure patients' subjective attitudes towards their health or health-related conditions in various fields have been increasingly used in randomised controlled trials (RCTs). PRO data is likely to be bounded, discrete, and skewed. Although various statistical methods are available for the analysis of PROs in RCT settings, there is no consensus on what statistical methods are the most appropriate for use. This study aims to use simulation methods to compare the performance (in terms of bias, empirical standard error, coverage of the confidence interval, Type I error, and power) of three different statistical methods, multiple linear regression (MLR), Tobit regression (Tobit), and median regression (Median), to estimate a range of predefined treatment effects for a PRO in a two-arm balanced RCT. We assumed there was an underlying latent continuous outcome that the PRO was measuring, but the actual scores observed were equally spaced and discrete. This study found that MLR was associated with little bias of the estimated treatment effect, small standard errors, and appropriate coverage of the confidence interval under most scenarios. Tobit performed worse than MLR for analysing PROs with a small number of levels, but it had better performance when analysing PROs with more discrete values. Median showed extremely large bias and errors, associated with low power and coverage for most scenarios especially when the number of possible discrete values was small. We recommend MLR as a simple and universal statistical method for the analysis of PROs in RCT settings.

Effect of heart rate control with ivabradine on hemodynamic in patients with sepsis: study protocol for a prospective, multicenter, randomized controlled trial

INTRODUCTION

Sepsis, a life-threatening syndrome, is often accompanied by tachycardia in spite of hypovolemia and hypotension have been corrected. Recently, relevant studies have shown that sustained tachycardia in sepsis was related to high mortality, and appropriate control of heart rate (HR) could improve prognosis. Ivabradine reduces HR directly without a negative inotropic effect through inhibition of the If ionic current, which is different from the traditional rate control drug (beta-blockers).

METHODS AND ANALYSIS

This is a prospective, multicenter, randomized, open label study designed to investigate the effect of heart rate control with ivabradine on hemodynamic in patients with sepsis. Our study will enroll 172 patients with sepsis as defined by The Third International Consensus Definitions for Sepsis and Septic Shock criteria with sinus rate of 95 bpm or higher despite a hemodynamic optimization. Patients will be randomly assigned to standard treatment group (GS) or ivabradine group (GI, standard treatment for sepsis plus enteral ivabradine). Patients in GI will receive ivabradine to maintain HR between 70 and 94 bpm. The primary outcome is the difference of a reduction in HR below 95 bpm and the effect of ivabradine on hemodynamics between GI and GS group within the first 96 h after randomization. The secondary outcomes include organ function measures, the difference in SOFA score, incidence of adverse events, need for organ support, length of ICU stay, and 28-day overall mortality.

DISCUSSION

There are limited studies on ivabradine to control heart rate in patients with sepsis. Our study aims to evaluate whether direct sinus node inhibition can improve hemodynamics, as well as its impact on organ function and prognosis in patients with sepsis, so as to provide evidence for the safe usage in clinical practice.

Is Reiki effective in reducing heart rhythm, cortisol levels, and anxiety and improving biochemical parameters in individuals with cardiac disease? Randomized placebo-controlled trial

AIMS

The aim of this study was to examine the effect of Reiki in patients with cardiac disease.

METHODS AND RESULTS

This study was a single-blind, pre-post-test, randomized, placebo-controlled study. Patients from the cardiology outpatient clinic of a training and research hospital were randomized into three groups: Reiki (n = 22), sham (placebo) (n = 21), and control (no treatment) (n = 22). Data were collected using a personal information form, biochemical parameters, cortisol levels, Beck Anxiety Inventory, and electrocardiography analysis. The Reiki group received Reiki to nine main points for 30 min, while the sham Reiki group received the same points during the same period without starting the energy flow. On Day 2, distance Reiki was performed for 30 min. After 1 week, the researchers administered the Beck Anxiety Inventory, assessed the biochemical parameters and cortisol levels, and analysed the electrocardiography again. Of the patients, 52.3% were male and 47.7% were female, and the mean age (years) was 60.45 ± 9.67 years. The control group had a significantly higher post-test cortisol level than the other groups (P = 0.002). According to the post hoc analysis, there was a significant difference between the Reiki vs. control groups and sham vs. control groups (P = 0.002). The control group had a significantly higher post-test cortisol level than the pre-test cortisol level (P = 0.008). Reiki group had a significantly lower mean post-test Beck Anxiety Inventory score than the other groups (P < 0.001). There was no difference between the electrocardiography results of the groups (P > 0.05).

CONCLUSION

Reiki reduces blood cortisol levels and anxiety levels in patient with cardiac diseases.

Home-based transcranial direct current stimulation treatment for major depressive disorder: a fully remote phase 2 randomized sham-controlled trial

Transcranial direct current stimulation (tDCS) has been proposed as a new treatment in major depressive disorder (MDD). This is a fully remote, multisite, double-blind, placebo-controlled, randomized superiority trial of 10-week home-based tDCS in MDD. Participants were 18 years or older, with MDD in current depressive episode of at least moderate severity as measured using the Hamilton Depression Rating Scale (mean = 19.07 ± 2.73). A total of 174 participants (120 women, 54 men) were randomized to active (n = 87, mean age = 37.09 ± 11.14 years) or sham (n = 87, mean age = 38.32 ± 10.92 years) treatment. tDCS consisted of five sessions per week for 3 weeks then three sessions per week for 7 weeks in a 10-week trial, followed by a 10-week open-label phase. Each session lasted 30 min; the anode was placed over the left dorsolateral prefrontal cortex and the cathode over the right dorsolateral prefrontal cortex (active tDCS 2 mA and sham tDCS 0 mA, with brief ramp up and down to mimic active stimulation). As the primary outcome, depressive symptoms showed significant improvement when measured using the Hamilton Depression Rating Scale: active 9.41 ± 6.25 point improvement (10-week mean = 9.58 ± 6.02) and sham 7.14 ± 6.10 point improvement (10-week mean = 11.66 ± 5.96) (95% confidence interval = 0.51-4.01, P = 0.012). There were no differences in discontinuation rates. In summary, a 10-week home-based tDCS treatment with remote supervision in MDD showed high efficacy, acceptability and safety.

Stem cell treatment for regeneration of the rotator cuff: study protocol for a prospective single-center randomized controlled trial (Lipo-cuff)

BACKGROUND

Rotator cuff tears (RCT) are a common musculoskeletal condition, especially in the aging population. The prevalence of rotator cuff tears varies based on factors like age, occupation, and activity level. In the general population, the prevalence of rotator cuff tears is estimated to be around 20 to 25%. Rotator cuff tears (RCT) have an impact in patients' pain level, shoulder function, sleep disturbance, and quality of life. Primary tendon surgery is in mostly cases necessary. This study aimed to examine if treatment of rotator cuff lesions with implantation of micro-fragmented adipose tissue can improve patients' reported pain and function compared to conventional surgery.

METHODS

The study is a prospective superiority parallel-group single-center randomized controlled trial including 30 patients between 40 and 69 years of age in Denmark. Patients will be allocated 1:1 ratio to reconstruction of the supraspinatus tendon with an injection of micro-fragmented adipose tissue into the related muscle (stem cell treatment) or the standard of care (SOC), which is conventional surgery. Patients, project assistants, physicians, and outcome adjudicators are not blinded to randomization due to practical constraints. The radiologist and the statistician performing the analysis will be blinded. The primary outcome will be the Oxford shoulder score at 12 months post-surgery.

DISCUSSION

This study will assess whether adding micro-fragmented adipose tissue therapy to conventional rotator cuff tear treatment can enhance recovery, accelerate return to daily activities, and improve functional outcomes. The research will also determine if this minimally invasive procedure could be standardized for routine patient care.

A Nonparametric Global Win Probability Approach to the Analysis and Sizing of Randomized Controlled Trials With Multiple Endpoints of Different Scales and Missing Data: Beyond O'Brien-Wei-Lachin

Multiple primary endpoints are commonly used in randomized controlled trials to assess treatment effects. When the endpoints are measured on different scales, the O'Brien rank-sum test or the Wei-Lachin test for stochastic ordering may be used for hypothesis testing. However, the O'Brien-Wei-Lachin (OWL) approach is unable to handle missing data and adjust for baseline measurements. We present a nonparametric approach for data analysis that encompasses the OWL approach as a special case. Our approach is based on quantifying an endpoint-specific treatment effect using the probability that a participant in the treatment group has a better score than (or a win over) a participant in the control group. The average of the endpoint-specific win probabilities (WinPs), termed the global win probability (gWinP), is used to quantify the global treatment effect, with the null hypothesis gWinP = 0.50. Our approach involves converting the data for each endpoint to endpoint-specific win fractions, and modeling the win fractions using multivariate linear mixed models to obtain estimates of the endpoint-specific WinPs and the associated variance-covariance matrix. Focusing on confidence interval estimation for the gWinP, we derive sample size formulas for clinical trial design. Simulation results demonstrate that our approach performed well in terms of bias, interval coverage percentage, and assurance of achieving a pre-specified precision for the gWinP. Illustrative code for implementing the methods using SAS PROC RANK and PROC MIXED is provided.

Effects of 3D-printed ankle-foot orthoses on gait: a systematic review

This systematic review aimed to explore comprehensive evidence on the efficacy of the 3D-printed ankle-foot orthoses (AFOs) on gait parameters in individuals with neuromuscular and/or musculoskeletal ankle impairments. Electronic databases including PubMed, Scopus, Web of Science, Embase, ProQuest, Cochrane, and EBSCOhost were searched from inception to August 2023. Ten studies that had participants with ankle impairments, as a result of stroke, cerebral palsy, mechanical trauma, muscle weakness, or Charcot-Marie-Tooth disease, investigated the immediate effects of the 3D-printed AFOs on gait parameters were included. Methodological rigor was evaluated using the modified Downs & Black index. The gait parameters included lower extremity joint angles, moments, and work/power, plantar pressures, spatiotemporal measures, and patient satisfaction were improved with the 3D-printed AFOs when compared to the no-AFO (i.e. barefoot, or shoe-only) conditions. 3D-printed AFOs revealed similar functional efficacy as conventional AFOs. Notably, the level of patient satisfaction regarding fitting and comfort was higher with the 3D-printed AFOs. Although the study on the effects of the 3D-printed AFOs are limited, emerging evidence indicates their effectiveness in improving gait biomechanics and functions. To further confirm their effects, rigorous randomized control studies with larger sample sizes and longer follow-ups on the effects are warranted in the future.

Overall Reporting Quality of Randomized Controlled Trials of Acupuncture for Knee Osteoarthritis: A Systematic Review

Objective

To evaluate the reporting quality of randomized controlled trials (RCT) of acupuncture for knee osteoarthritis and explore factors associated with the reporting.

Study Design and Setting

Eight databases were searched from inception to August 2024 to assess the quality of acupuncture for knee osteoarthritis RCTs based on the CONSORT, the STRICTA, and the CONSORT-Outcomes. We performed regression analyses on pre-specified study characteristics to explore factors associated with reporting quality.

Results

One hundred and seventy-four RCTs were evaluated by 69 items from 3 checklists. Seventeen of 37 items on the CONSORT were under-reported (reported in less than 20% of RCTs), and the weakest reported item was why the trial ended or was stopped (0%). Four of 17 items on the STRICTA were under-reported, and the weakest reported item was the number of needle insertions per subject per session (9.2%). Eight of 17 items on the CONSORT-Outcomes were under-reported, and the weakest reported item was identifying any outcomes that were not pre-specified in a trial registry or trial protocol (0.6%). RCT locations include countries other than China, published in English, or funded were more likely to have better reporting.

Conclusion

RCTs of acupuncture for knee osteoarthritis need to focus more on reporting details of acupuncture interventions, the reporting of protocol amendment, and the complete reporting of outcome-related content. Journals should encourage authors to adhere strictly to reporting guidelines, which is necessary to improve the quality of reporting, which is very important for Chinese journals.

High-load strength training compared with standard care treatment in young adults with joint hypermobility and knee pain: study protocol for a randomised controlled trial (the HIPEr-Knee study)

INTRODUCTION

Patients with generalised joint hypermobility, including knee hypermobility (GJHk), often experience knee pain and are typically managed with low-intensity strength training and/or proprioceptive training as part of standard care. However, not all patients experience satisfactory outcomes. High-load strength training may offer additional benefits, such as increased muscle cross-sectional area, neural drive and tendon stiffness, which may reduce pain and improve active knee joint stability during movement tasks and daily activities. So far, no randomised controlled trials (RCTs) have compared high-load strength training with traditional treatment strategies (standard care) for this patient group.

METHODS AND ANALYSIS

In this RCT, we aim to recruit patients with GJHk and knee pain from primary care physiotherapy clinics in the Region of Southern Denmark and via social media. Patients with competing injuries or experience with high-load strength training will be excluded. Patients will be randomised (1:1 ratio) to either 2 weekly sessions of high-load strength training or standard care for 12 weeks. The primary outcome is self-reported knee pain during an activity nominated by the patient as the most aggravating for their present knee pain measured using the Visual Analogue Scale for Nominated Activity (VASNA, 0-100; 0=no pain and 100=worst imaginable pain). This will be collected at baseline, 6 weeks, 12 weeks and 12 months. Secondary outcomes include self-reported knee function and adverse events (collected at baseline, 12 weeks and 12 months), objective measurements including a 5-repetition maximum single-leg press, proprioception and single-leg-hop for distance (collected at baseline and 12 weeks), and a range of other outcome measures such as fear of movement, tendon stiffness and global perceived effect. We aim to recruit 90 patients in total to detect a 10 mm group difference in the primary outcome with 80% power.

ETHICS AND DISSEMINATION

This study was funded by Independent Research Fund Denmark (grant number 2034-00088B) on 14 June 2022; the Regional Committees on Health Research Ethics for Southern Denmark approved it (S-20230050) on 30 August 2023. The first recruitment site opened on 15 February 2024, and the final results will be submitted to a peer-reviewed journal to inform rehabilitation strategies for symptomatic GJHk.Protocol version 1, dated 4 July 2024.

Deciphering the role of miRNA-134 in the pathophysiology of depression: A comprehensive review

This study summarizes the significance of microRNA-134 (miRNA-134) in the pathophysiology, diagnosis, and treatment of depression, a disease still under investigation due to its complexity. miRNA-134 is an endogenous short non-coding RNA that can bind to the 3' untranslated region (3'UTR) of miRNA-134, inhibiting gene translation and showing great potential in the regulation of mood, synaptic plasticity, and neuronal function. This study included 15 articles retrieved from four English-language databases: PubMed, Embase, The Cochrane Library, and Web of Science, and three Chinese literature databases: CNKI, Wanfang, and Chinese Science and Technology Periodical Database (VIP).We evaluated each of the 15 articles using the Critical Appraisal Skills Program (CASP) tool.The standard integrates analyzes of genomic, transcriptomic, neuroimaging, and behavioral data analyses related to miRNA-134 and depression. A multidimensional framework based on standardized criteria was used for quality assessment. The main findings indicate that miRNA-134 significantly affects synaptic plasticity and neurotransmitter regulation, in particular the synthesis and release of serotonin and dopamine. miRNA-134 shows high sensitivity and specificity as a biomarker for the diagnosis of depression and has therapeutic potential for the targeted treatment of depression. miRNA-134 plays a crucial role in the pathogenesis of depression, providing valuable insights for early diagnosis and the development of targeted therapeutic strategies. This work highlights the potential of miRNA-134 as a focal point for advancing personalized medicine approaches for depression.

The effect of neurofeedback and somatosensory exercises on balance and physical performance of older adults: a parallel single-blinded randomized controlled trial

This study examines the effects of a 5-week program of neurofeedback combined with somatosensory exercises on balance and physical performance in older adults, with the goal of addressing age-related declines in sensory processing and motor function. Sixty older adult men with balance disorders were randomly assigned to one of three groups: neurofeedback combined with somatosensory training, somatosensory training alone, or a control group. The interventions were administered over 5 weeks, with participants attending three sessions per week. Assessments were conducted both before and after the intervention period, including measurements of static balance using the Stork test, dynamic balance using the Timed Up and Go (TUG) test, and physical performance using the Continuous Scale Physical Functional Performance-10 (CS-PFP-10) test. The findings revealed significant improvements in balance and physical performance among participants who received either neurofeedback combined with somatosensory training or somatosensory training alone. Specifically, the Stork test (with both open and closed eyes) showed significant increases in duration, while the TUG test indicated reductions in completion times for both intervention groups (p = 0.001), suggesting enhanced balance and mobility. Additionally, the CS-PFP-10 test results demonstrated a significant difference following the interventions (p = 0.001). These findings suggest that incorporating neurofeedback training into somatosensory exercises may provide additional benefits for older adults in improving balance and mobility.

Hypothermia versus normothermia in patients with cardiac arrest and shockable rhythm: a secondary analysis of the TTM-2 study

BACKGROUND

The aim of this study was to assess whether hypothermia increased survival and improved functional outcome when compared with normothermia in out-of-hospital cardiac arrest (OHCA) patients with similar characteristics than in previous randomized studies showing benefits for hypothermia.

METHODS

Post hoc analysis of a pragmatic, multicenter, randomized clinical trial (TTM-2, NCT02908308). In this analysis, the subset of patients included in the trial who had similar characteristics to patients included in one previous randomized trial and randomized to hypothermia at 33 °C or normothermia (i.e. target < 37.8 °C) were considered. The primary outcome was survival at 6 months; secondary outcomes included favorable functional outcome at 6 months, defined as a modified Rankin scale of 0-3. Time-to-death and the occurrence of adverse events were also reported.

RESULTS

From a total of 1891 included in the TTM-2 study, 600 (31.7%) were included in the analysis, 294 in the hypothermia and 306 in the normothermia group. At 6 months, 207 of the 294 patients (70.4%) in the hypothermia group and 220 of the 306 patients (71.8%) in the normothermia group had survived (relative risk with hypothermia, 0.96; 95% confidence interval [CI], 0.81 to 1.15; P = 0.71). Also, 198 of the 294 (67.3%) in the hypothermia group and 202 of the 306 (66.0%) in the normothermia group had a favorable functional outcome (relative risk with hypothermia, 1.03; 95% CI, 0.87 to 1.23; P = 0.79). There was a significant increase in the occurrence of arrythmias in the hypothermia group (62/294, 21.2%) when compared to the normothermia group (43/306, 14.1%-OR 1.49, 95% CI 1.05-2.14; p = 0.026).

CONCLUSIONS

In this study, hypothermia at 33˚C did not improve survival or functional outcome in a subset of patients with similar cardiac arrest characteristics to patients in whom benefit from hypothermia was shown in prior studies.

Efficacy of facilitated tucking position and Reiki given to preterm infants during orogastric tube insertion: A randomised controlled trial

AIM

This research was conducted to evaluate the effects of Reiki and facilitated tucking position on pain, stress and physiologic parameters in preterm infants during orogastric tube (OGT) insertion.

METHODS

The study used a single-blind, parallel-group randomised controlled experimental design. It was carried out in the neonatal intensive care unit of a hospital in Niğde/Turkey between February 2022 and January 2023. A total of 45 preterm infants, who met the study criteria and whose sample size was determined according to power analysis, were randomly divided into three groups. As an intervention, the facilitated tucking position was applied to the first group, and Reiki was applied to the second group during OGT insertion. Routine application continued in the control group. The Infant Introductory Information Form, Physiological Parameter Follow-up Chart, Infant Stress Scale (ISS) and Premature Infant Pain Profile Scale-Revised (PIPP-R) were used for data collection. Significance was accepted as P < 0.05 in the statistical analysis.

RESULTS

It was determined that the infants were homogeneously distributed between the experimental and control groups (P > 0.05). Infants who received the facilitated tucking position and Reiki intervention had better physiological stability compared to the control group (P < 0.05). The group with the lowest average stress (1.53 ± 0.99) and pain scores (4.06 ± 1.22) during OGT insertion was the facilitated tucking group (P < 0.001). After the procedure, stress and pain scores in both the facilitated tucking group and the Reiki group were found to be significantly lower than those in the control group (P < 0.001).

CONCLUSIONS

The results of the study showed that the facilitated tucking position during OGT insertion was especially effective in reducing the pain and stress of infants. Both the facilitated tucking position and Reiki were determined to be effective interventions in reducing the pain and stress of infants more quickly after the procedure. The results of study contribute to the recommendation that NICU nurses should include non-pharmacological methods to decrease the pain of preterm infants during procedural pain.

Online Mental Health Assessment in a psychiatry emergency department in adults using touchscreen mobile devices: A randomised controlled trial

OBJECTIVE

To determine whether completion of an online mental health self-assessment by patients who are waiting in the emergency department can save clinician time taken to complete clinical assessment and documentation.

METHODS

Patients presenting to a psychiatric emergency department for a period of 6 months were allocated by week of presentation to either the intervention arm (online mental health self-assessment, followed by a clinical interview) or the control arm (usual assessment) arm on a random basis. Time at the beginning and end of the interview was recorded and used to derive interview time. Similarly, time at the beginning and end of the clinical documentation was recorded and used to derive the time to complete clinical documentation.

RESULTS

Of 168 patients who presented during the study period, 69 (38.55%) agreed to participate, 33 completed the usual assessment and 30 completed the online mental health self-assessment followed by a clinical interview. Patients receiving usual care had a statistically significant, t(61) = 2.15, p = 0.035, longer interview duration (M = 48.7 minutes, SD = 19.8) compared with those in the online mental health self-assessment arm (M = 38.9 minutes, SD = 15.9). There was no statistically significant difference between groups for documentation time, t(61) = -0.64, p = 0.52.

CONCLUSION

Online mental health self-assessment was associated with a statistically significant reduction in interview time by approximately 10 minutes without increasing documentation time. While online mental health self-assessment is not appropriate for all patients in the emergency department setting, it is likely to yield greater benefits in less acute settings.

Acute Effects of Citrulline Malate Supplementation on Nocturnal Blood Pressure Dipping After Exercise in Hypertensive Patients: A Randomized, Placebo-Controlled Trial

BACKGROUND

Citrulline malate (CM), especially when used in conjunction with physical exercise, has demonstrated potential as a non-pharmacological adjunct in the management of hypertension. Nevertheless, its impact on nocturnal blood pressure dipping remains unexplored.

OBJECTIVE

Evaluate the impact of a single dose of CM on nocturnal blood pressure dipping after exercise in hypertensive individuals.

METHODS

In a double-blind, placebo-controlled, parallel-group clinical trial, twenty hypertensive adults (55 ± 16 years) were randomly assigned to either a CM (6 g) or placebo (6 g of corn starch) group (PLA). Resting blood pressure was measured after a 20-min period of comfortable seating in a calm environment. Both groups underwent 40 min of treadmill running/walking at an intensity of 60-70% of their reserve heart rate, 120 min after ingesting the substances. Ambulatory blood pressure monitoring was employed to measure blood pressure over 24 h.

RESULTS

No significant differences in systolic blood pressure values were observed between the CM and PLA groups at rest, during wakefulness, sleep, or over a 24-h period. However, CM exhibited a significant reduction in diastolic blood pressure in several metrics: delta 24 h (-14 mmHg vs -6 mmHg, p = 0.047), delta wakefulness (-12 mmHg vs -4 mmHg, p = 0.024), percent delta 24 h (-16% vs -6%, p = 0.024), and percent delta wakefulness (-14% vs -4%, p = 0.013). No significant differences were found between CM and PLA in terms of systolic and diastolic nocturnal absolute reductions (-13 mmHg vs -12 mmHg, p = 0.808, and -13 mmHg vs -8 mmHg, p = 0.273, respectively) or nocturnal percentage decrease (-9.9% vs -9.4%, p = 0.844, and -15.3% vs -11.7%, p = 0.399, respectively).

CONCLUSIONS

The study found no significant changes in the post-exercise nocturnal blood pressure dip following a single dose of CM supplementation. However, a notable reduction in diastolic blood pressure was observed during the waking period and over the average 24-h monitoring period.

A multicentric, randomized, controlled clinical trial to study the impact of bedside model-informed precision dosing of vancomycin in critically ill children-BENEFICIAL trial

BACKGROUND

Vancomycin is a commonly prescribed antibiotic to treat serious Gram-positive infections in children. The efficacy of vancomycin is known to be directly related to the pharmacokinetic/pharmacodynamic (PK/PD) index of the area under the concentration-time curve (AUC) divided by the minimal inhibitory concentration (MIC) of the pathogen. In most countries, steady-state plasma concentrations are used as a surrogate parameter for this target AUC/MIC, but this practice has some drawbacks. Hence, AUC-based dosing using model-informed precision dosing (MIPD) tools has been proposed for increasing the target attainment rate and reducing vancomycin-related nephrotoxicity. Solid scientific evidence for these claimed benefits is lacking in children. This randomized controlled trial aims to investigate the large-scale utility of MIPD dosing of vancomycin in critically ill children.

METHODS

Participants from 14 neonatal intensive care, pediatric intensive care, and pediatric hemo-oncology ward units from 7 hospitals are randomly allocated to the intervention or standard-of-care comparator group. In the intervention group, a MIPD dosing calculator is used for AUC-based dosing, in combination with extra sampling for therapeutic drug monitoring in the first hours of treatment, as compared to standard-of-care. An AUC24h between 400 and 600 is targeted, assuming an MIC of 1 mg/L. Patients in the comparator group receive standard-of-care dosing and monitoring according to institutional guidelines. The primary endpoint is the proportion of patients reaching the target AUC24h/MIC of 400-600 between 24 and 48 h after the start of vancomycin treatment. Secondary endpoints are the proportion of patients with (worsening) acute kidney injury during vancomycin treatment, the proportion of patients reaching target AUC24h/MIC of 400-600 between 48 and 72 h after the start of vancomycin treatment, time to clinical cure, ward unit length-of-stay, hospital length-of-stay, and 30-day all-cause mortality.

DISCUSSION

This trial will clarify the propagated benefits and provide new insights into how to optimally monitor vancomycin treatment in critically ill children.

Restrictive vs Liberal Transfusion Strategy in Patients With Acute Brain Injury: The TRAIN Randomized Clinical Trial

Importance

Blood transfusions are commonly administered to patients with acute brain injury. The optimal hemoglobin transfusion threshold is uncertain in this patient population.

Objective

To assess the impact on neurological outcome of 2 different hemoglobin thresholds to guide red blood cell transfusions in patients with acute brain injury.

Design, Setting, and Participants

Multicenter, phase 3, parallel-group, investigator-initiated, pragmatic, open-label randomized clinical trial conducted in 72 intensive care units across 22 countries. Eligible patients had traumatic brain injury, aneurysmal subarachnoid hemorrhage, or intracerebral hemorrhage; hemoglobin values below 9 g/dL within the first 10 days after injury; and an expected intensive care unit stay of at least 72 hours. Enrollment occurred between September 1, 2017, and December 31, 2022. The last day of follow-up was June 30, 2023.

Interventions

Eight hundred fifty patients were randomly assigned to undergo a liberal (transfusion triggered by hemoglobin <9 g/dL; n = 408) or a restrictive (transfusion triggered by hemoglobin <7 g/dL; n = 442) transfusion strategy over a 28-day period.

Main Outcomes and Measures

The primary outcome was occurrence of an unfavorable neurological outcome, defined as a Glasgow Outcome Scale Extended score between 1 and 5, at 180 days following randomization. There were 14 prespecified serious adverse events, including occurrence of cerebral ischemia after randomization.

Results

Among 820 patients who completed the trial (mean age, 51 years; 376 [45.9%] women), 806 had available data on the primary outcome, 393 in the liberal strategy group and 413 in the restrictive strategy group. The liberal strategy group received a median of 2 (IQR, 1-3) units of blood, and the restrictive strategy group received a median of 0 (IQR, 0-1) units of blood, with an absolute mean difference of 1.0 unit (95% CI, 0.87-1.12 units). At 180 days after randomization, 246 patients (62.6%) in the liberal strategy group had an unfavorable neurological outcome compared with 300 patients (72.6%) in the restrictive strategy group (absolute difference, -10.0% [95% CI, -16.5% to -3.6%]; adjusted relative risk, 0.86 [95% CI, 0.79-0.94]; P = .002). The effect of the transfusion thresholds on neurological outcome at 180 days was consistent across prespecified subgroups. In the liberal strategy group, 35 (8.8%) of 397 patients had at least 1 cerebral ischemic event compared with 57 (13.5%) of 423 in the restrictive strategy group (relative risk, 0.65 [95% CI, 0.44-0.97]).

Conclusions and Relevance

Patients with acute brain injury and anemia randomized to a liberal transfusion strategy were less likely to have an unfavorable neurological outcome than those randomized to a restrictive strategy.

Preoperative Smoking-Cessation Interventions to Prevent Postoperative Complications: A Quality Assessment and Overview of Systematic Review Evidence

Multiple systematic reviews have investigated the effectiveness of preoperative interventions for smoking-cessation, although relatively few have focused on the prevention of surgical complications. This overview of systematic reviews aimed to describe the types of smoking interventions studied to prevent postoperative complications, summarize the results, and evaluate the quality of the reviews and strength of evidence to inform clinicians, health practitioners, policy developers, and government bodies. Comprehensive searches of Cochrane Library, MEDLINE, EMBASE, CINAHL, and Johanna Briggs Institute databases were conducted to identify systematic reviews of preoperative smoking-cessation interventions to prevent surgical complications (inception-May 14, 2024). Search results were independently screened by 2 reviewers for articles meeting the eligibility criteria. Data on key review characteristics and included studies were extracted: aim, search strategy, included studies, risk of bias, population, sample size, intervention, comparator, main findings, and conclusions. Quality appraisal of the reviews was undertaken using the AMSTAR 2 tool and evidence certainty was evaluated using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Sixty-seven full-text articles from 838 citations were screened, resulting in 6 included systematic reviews with 12 primary studies reporting postoperative complications. Four reviews which included all primary studies, provided moderate to high strength of evidence. There was high-certainty evidence suggesting interventions started ≥4 weeks before surgery incorporating multiple behavioral support sessions and pharmacotherapy are needed to prevent postoperative complications, particularly the incidence of surgical site infections. High-certainty evidence also indicates the duration of smoking-cessation is important, with benefits amplified for longer periods. However, medium- to high-certainty evidence suggests interventions initiated <4 weeks before surgery even with multiple behavioral support sessions (with or without pharmacotherapy), and interventions commenced >4 weeks before surgery but with only 1 interventional component, increase quit rates but do not reduce complications. This overview provides the most up-to-date summary and quality assessment of systematic review evidence on the effectiveness of preoperative smoking-cessation interventions to prevent surgical complications. The evidence supports providing smoking-cessation interventions which include multiple behavioral support sessions and pharmacotherapy implemented at least 4 weeks before surgery to reduce postoperative complications. Consequently, anesthesiologists need to work with primary care physicians, consultants, and surgeons to optimize smoking-cessation interventions way in advance of surgery.

Wii Fit Exercise's Effects on Muscle Strength and Fear of Falling in Older Adults With Alzheimer Disease: A Randomized Controlled Trial

PURPOSE

This study aimed to investigate how Wii Fit exercises affect muscle strength and fear of falling in older adults with Alzheimer's disease.

METHOD

The study included a total of 32 volunteers with Alzheimer's disease, aged 65-80 years. These participants were divided into two groups: the exercise group and the control group. The exercise group received a 30-min (one session) twice-weekly exercise program for 6 weeks with games selected from different categories, such as balance and aerobic exercises, with the Nintendo Wii virtual reality device. During this period, the control group did not receive any treatment, and routine medical treatments continued. At baseline and 6 weeks later, Mini-Mental State Examination, knee extension muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale results were recorded in the exercise and control groups.

RESULTS

In intragroup comparison, a statistically significant difference was found in all tests (muscle strength, Timed Up and Go Test, and Tinetti Fall Efficacy Scale) in the exercise group after the exercise program (p < .05), while no significant difference was found in the control group (p > .05). According to the interaction of group and time in the intergroup comparison, there was no difference between the groups (exercise and control group) in muscle strength and Timed Up and Go Test (p > .05), but there was a difference in Tinetti Fall Efficacy Scale (p < .05).

CONCLUSIONS

This randomized controlled trial supports the claim that Wii Fit exercises can reduce the fear of falling in older adults with Alzheimer's disease.

Facial soft tissue changes in adolescent patients treated with three different functional appliances: a randomized clinical trial

INTRODUCTION

Patients with Class II, division 1 malocclusion generally seek treatment to improve facial esthetics. Therefore, the orthodontist needs to know the changes in the soft profile produced by functional appliances.

OBJECTIVE

This study evaluated the soft tissue profile changes in patients treated during the peak of the pubertal growth spurt.

METHODS

Thirty selected patients were randomized into three treatment groups: Twin Block (TB), Herbst with dental anchorage (HDA), and Herbst with skeletal anchorage (HSA). All patients had computed tomographic images: pretreatment (T1) and after 12 months of active treatment (T2). Twenty-four soft tissue cephalometric measures were analyzed. The normality of all data was assessed by the Shapiro-Wilk test. Intragroup comparisons were analyzed using the t-paired test; the inter-group comparisons were determined through ANOVA and the post-hoc Tukey test.

RESULTS

At T1, no significant differences were observed between groups. At T2, in the intragroup comparison, facial soft tissue changes were statistically significant in the three groups for the lower lip, sulcus inferioris, facial soft tissue convexity in HDA group and TB group, and H angle in HDA group and HSA group, and soft tissue pogonium in TB group. In the inter-group comparison, no statistically significant differences were observed.

CONCLUSION

It can be concluded that there were significant changes in soft tissue measurements that benefited Class II, division 1 patient's facial profile treated with the functional appliances Twin Block, Herbst, and Herbst with skeletal anchorage. Nevertheless, no significant differences were detected among the effects obtained by the three treatment protocols.

Silicone Irregular Hexagon Pessary Versus Polyvinyl Chloride Ring Pessary for Pelvic Organ Prolapse: Randomised Controlled Trial

INTRODUCTION AND HYPOTHESIS

Vaginal pessaries are the mainstay of the non-surgical management of pelvic organ prolapse (POP). A flexible silicone irregular hexagonal (SIH) pessary was developed based on the results of a prior vaginal case study. We hypothesised that the SIH pessary would have a higher rate of retention and self-management than the polyvinyl chloride (PVC) pessary.

METHODS

This was a prospective non-blinded, randomised controlled trial with institutional review board approval. Eligible participants were randomised and fitted with the assigned pessary. They were reviewed 1 week, 6 months and 1 year after the initial pessary fitting. Participants who returned for follow-up completed the study questionnaires. The primary outcome was success, defined as continued use of the allocated pessary at 6 months. Secondary outcomes included the ability to perform pessary self-care, treatment satisfaction and pessary-related complications. Statistical tests were performed with alpha or statistical significance defined as a p value of ≤ 0.05, two-tailed.

RESULTS

A total of 104 participants were randomised, with 52 subjects in each arm. Primary outcome data were analysed using per protocol analysis. Continuing pessary usage at 6 months was 68.1% for the PVC pessary group and 65.1% for the SIH group, with no statistically significant differences between the two groups (p = 0.765). Subjects with SIH were more likely to perform pessary self-care. There were no significant differences in subjects' satisfaction, quality-of-life scores or treatment complications between groups.

CONCLUSIONS

The pessary continuation rate between the SIH and the PVC pessary groups was similar at 6 months. Participants with an SIH pessary were more likely to self-manage.

Classifying compounds as prebiotics - scientific perspectives and recommendations

Microbiomes provide key contributions to health and potentially important therapeutic targets. Conceived nearly 30 years ago, the prebiotic concept posits that targeted modulation of host microbial communities through the provision of selectively utilized growth substrates provides an effective approach to improving health. Although the basic tenets of this concept remain the same, it is timely to address certain challenges pertaining to prebiotics, including establishing that prebiotic-induced microbiota modulation causes the health outcome, determining which members within a complex microbial community directly utilize specific substrates in vivo and when those microbial effects sufficiently satisfy selectivity requirements, and clarification of the scientific principles on which the term 'prebiotic' is predicated to inspire proper use. In this Expert Recommendation, we provide a framework for the classification of compounds as prebiotics. We discuss ecological principles by which substrates modulate microbiomes and methodologies useful for characterizing such changes. We then propose statistical approaches that can be used to establish causal links between selective effects on the microbiome and health effects on the host, which can help address existing challenges. We use this information to provide the minimum criteria needed to classify compounds as prebiotics. Furthermore, communications to consumers and regulatory approaches to prebiotics worldwide are discussed.

Eligible Infants Included in Neonatal Clinical Trials and Reasons for Noninclusion: A Systematic Review

Importance

Results of clinical trials can only represent included participants, and many neonatal trials fail due to insufficient participation. Infants not included in research may differ from those included in meaningful ways, biasing the sample and limiting the generalizability of findings.

Objective

To describe the proportion of eligible infants included in neonatal clinical trials and the reasons for noninclusion.

Evidence Review

A systematic search of Cochrane CENTRAL was performed by retrieving articles meeting the following inclusion criteria: full-length, peer-reviewed articles describing clinical trial results in at least 20 human infants from US neonatal intensive care units, published in English, and added to Cochrane CENTRAL between 2017 and 2022. Retrieved articles were screened for inclusion by 2 independent researchers.

Findings

In total 120 articles met inclusion criteria and 91 of these (75.8%) reported the number of infants eligible for participation, which totaled 26 854 in aggregate. Drawing from these, an aggregate of 11 924 eligible infants (44.4%) were included in reported results. Among all eligible infants, most reasons for noninclusion in results were classified as modifiable or potentially modifiable by the research team. Parents declining to participate (8004 infants [29.8%]) or never being approached (2507 infants [9.3%]) were the 2 predominant reasons for noninclusion. Other modifiable reasons included factors related to study logistics, such as failure to appropriately collect data on enrolled infants (859 of 26 854 infants [3.2%]) and other reasons (1907 of 26 854 infants [7.1%]), such as loss to follow-up or eligible participants that were unaccounted for. Nonmodifiable reasons, including clinical change or death, accounted for a small proportion of eligible infants who were not included (858 of 26 854 infants [3.2%]).

Conclusions and Relevance

This systematic review of reporting on eligible infants included and not included in neonatal clinical trials highlights the need for improved documentation on the flow of eligible infants through neonatal clinical trials and may also inform recruitment expectations for trialists designing future protocols. Improved adherence to standardized reporting may clarify which potential participants are being missed, improving understanding of the generalizability of research findings. Furthermore, these findings suggest that future work to understand why parents decline to participate in neonatal research trials and why some are never approached about research may help increase overall participation.

The relationship between blinding integrity and medication efficacy in randomised-controlled trials in patients with anxiety disorders: A systematic review and meta-analysis

BACKGROUND

Blinding is thought to minimise expectancy effects and biases in double-blind randomised-controlled trials (RCTs). However, whether blinding integrity should be assessed and reported remains debated. Furthermore, it is unknown whether blinding failure influences the outcome of RCTs in anxiety disorders. We carried out a systematic review to understand whether blinding integrity is assessed and reported in anxiolytic RCTs. A secondary aim was to explore whether blinding integrity is associated with treatment efficacy.

METHOD

Our protocol was pre-registered (PROSPERO CRD42022328750). We searched electronic databases for placebo-controlled, randomised trials of medication in adults with generalised and social anxiety disorders, and in panic disorder, from 1980. We extracted data regarding blinding integrity and treatment efficacy. Risk of bias was assessed with the Cochrane risk of bias tool. Where possible, we subsequently calculated Bang's Blinding Index, and assessed the association between blinding integrity and treatment effect size.

RESULTS

Of the 247 RCTs that met inclusion criteria, we were able to obtain assessments of blinding integrity from nine (3.64%). Overall, blinding failed in five of these trials (55.56%), but blinding was intact in 80% of placebo arms. We found a significant association between reduced blinding integrity among assessors and increased treatment effect size (betas < -1.30, p's < 0.001), but this analysis involved only four studies of which two were outlying studies. In patients, we saw a non-significant trend where reduced blinding integrity in the placebo groups was associated with increased treatment efficacy, which was not present in active medication arms. [Correction added on 19 August 2024, after first online publication: Results of the RCTs and its assessment of blinding integrity have been updated.] CONCLUSION: Consistent with work in other psychiatric disorders, blinding integrity is rarely reported in anxiolytic RCTs. Where it is reported, blinding appears to often fail. We found signals that suggest unblinding of clinician assessors (driven by two studies with complete unblinding), and of patients in placebo arms, might be associated with larger treatment effect sizes. We recommend that data regarding blinding integrity, along with the reasons patients and assessors offer for their beliefs regarding group allocation, are systematically collected in RCTs of anxiolytic treatment.

Feasibility of a co-designed online nutrition education program for people with multiple sclerosis

OBJECTIVE

Diet quality is important for people with multiple sclerosis (MS), but conflicting online information causes them confusion. People with MS want evidence-based MS-specific information to help them make healthy dietary changes, and we co-designed an asynchronous, online nutrition education program (Eating Well with MS) with the MS community. Our aim was to determine the feasibility of Eating Well with MS.

METHODS

We used a single-arm pre-post design. The feasibility trial was a nine-week intervention with adults with confirmed MS. Feasibility outcomes: 1) demand (recruitment); 2) practicality (completion); 3) acceptability (Intrinsic Motivation Inventory: interest/enjoyment and value/usefulness subscales); and 4) limited efficacy testing (Diet Habits Questionnaire (DHQ); Critical Nutrition Literacy Tool (CNLT); Food Literacy Behaviour Checklist (FLBC), using intention-to-treat analysis).

RESULTS

Recruitment (n = 70) exceeded the target (n = 48) within six weeks. Of the 70 enrolled, 84 % completed at least one module and 54 % completed the full program (five modules). The median interest/enjoyment rating was 5 out of 7 and median value/usefulness rating was 6 out of 7 (where 7 = 'very true'). Compared to pre-intervention, DHQ, CNLT, and FLBC scores all statistically significantly improved post-intervention.

CONCLUSION

Eating Well with MS was well received by the MS community and improved their dietary behaviours; demonstrating feasibility. Our findings support the use of co-design methods when developing resources to improve dietary behaviours.

Exploring TNFi drug-levels and anti-drug antibodies during tapering among patients with inflammatory arthritis: secondary analyses from the randomised BIODOPT trial

To evaluate tumour necrosis factor inhibitor (TNFi) drug-levels and presence of anti-drug antibodies (ADAb) in patients with inflammatory arthritis who taper TNFi compared to TNFi continuation. Patients with rheumatoid arthritis, psoriatic arthritis, or axial spondyloarthritis on stable TNFi dose and in low disease activity ≥ 12 months were randomised (2:1) to disease activity-guided tapering or control. Blood samples at baseline, 12- and 18-months were evaluated for TNFi drug-levels and ADAb. In total, 129 patients were randomised to tapering (n = 88) or control (n = 41). Between baseline and month 18, a significant shift in TNFi drug-levels were observed in the tapering group resulting in fewer patients with high drug-levels (change: - 14% [95% CI - 27 to - 1%]) and more with low drug-levels (change: 18% [95% CI 5-31%]). Disease activity was equivalent between groups at 18 months, mean difference: RA - 0.06 (95% CI - 0.44 to 0.33), PsA 0.03 (95% CI - 0.36 to 0.42), and axSpA 0.16 (- 0.17 to 0.49), equivalence margins ± 0.5 disease activity points. ADAb were detected in eight patients, all from the tapering group. TNFi drug-level category or ADAb were not predictive for achieving successful tapering at 18 months. TNFi drug-levels decreased during tapering which indicate adherence to the tapering algorithm. Despite the difference in TNFi drug-levels at 18 months, disease activity remained equivalent, and only few tapering patients had detectable ADAb. These data do not support using TNFi drug-level and/or ADAb to guide the tapering decision but future research with larger trials is needed.Trial registration: EudraCT: 2017-001970-41, December 21, 2017.

Tyrosine Kinase 2 Inhibition With Zasocitinib (TAK-279) in Psoriasis: A Randomized Clinical Trial

Importance

New, effective, and well-tolerated oral therapies are needed for treating psoriasis. Zasocitinib, a highly selective allosteric tyrosine kinase 2 (TYK2) inhibitor, is a potential new oral treatment for this disease.

Objective

To assess the efficacy, safety, and tolerability of zasocitinib in patients with moderate to severe plaque psoriasis.

Design, Setting, and Participants

This phase 2b, randomized, double-blind, placebo-controlled, multiple-dose randomized clinical trial was conducted from August 11, 2021, to September 12, 2022, at 47 centers in the US and 8 in Canada. The study included a 12-week treatment period and a 4-week follow-up period. Key eligibility criteria for participants included age 18 to 70 years; a Psoriasis Area and Severity Index (PASI) score of 12 or greater; a Physician's Global Assessment score of 3 or greater; and a body surface area covered by plaque psoriasis of 10% or greater. Of 287 patients randomized, 259 (90.2%) received at least 1 dose of study treatment.

Intervention

Patients were randomly assigned (1:1:1:1:1) to receive zasocitinib at 2, 5, 15, or 30 mg or placebo orally, once daily, for 12 weeks.

Main Outcomes and Measures

The primary efficacy end point was the proportion of patients achieving 75% or greater improvement in PASI score (PASI 75) at week 12. Secondary efficacy end points included PASI 90 and 100 responses. Safety was also assessed.

Results

In total, 259 patients were randomized and received treatment (mean [SD] age, 47 [13] years; 82 women [32%]). At week 12, PASI 75 was achieved for 9 (18%), 23 (44%), 36 (68%), and 35 (67%) patients receiving zasocitinib at 2, 5, 15, and 30 mg, respectively, and 3 patients (6%) receiving placebo. PASI 90 responses were consistent with PASI 75. PASI 100 demonstrated a dose response at all doses, with 17 patients (33%) achieving PASI 100 with zasocitinib, 30 mg. Treatment-emergent adverse events occurred for 23 patients (44%) receiving placebo and 28 (53%) to 31 (62%) patients receiving the 4 different doses of zasocitinib, with no dose dependency and no clinically meaningful longitudinal differences in laboratory parameters.

Conclusions and Relevance

This randomized clinical trial found that potent and selective inhibition of TYK2 with zasocitinib at oral doses of 5 mg or more once daily resulted in greater skin clearance than placebo over 12 weeks.

The impact of a continuous care model utilizing a smartphone application on quality of life and anxiety levels among gynecologic cancer patients: a randomized controlled trial

BACKGROUND

Patients diagnosed with gynecological cancers often face a range of complications that can impact their quality of life and increase their anxiety. Nursing models combined with mobile phone applications have the potential to improve outcomes for these patients. This study aimed to assess the impact of a continuous care model utilizing a smartphone application on quality of life and anxiety levels among gynecologic cancer patients.

METHODS

This study involved two phases: (1) mobile App development and (2) implementation of the intervention. The two-group randomized controlled trial included 70 participants with gynecological cancers referred to medical centers affiliated with Shahrekord University of Medical Sciences in 2023. The participants were randomized into control or intervention groups (n = 35 per group). Finally, 68 patients completed the trial. The intervention group received an 8-week intervention incorporating the continuous care model, whereas the control group received routine care (the standard support provided by nurses both during and after hospitalization). The participants completed the Spielberger state-trait anxiety and quality of life (QLQ-C30) questionnaires before, immediately after, and two months after the intervention. The data were analyzed via the chi-square test, independent samples t test, analysis of covariance, and repeated-measures ANOVA.

RESULTS

There were no significant differences in the baseline data between the two groups. However, after the intervention, the intervention group reported a significant increase in quality of life, with mean scores rising from 68.90 ± 17.50 to 73.78 ± 16.79 immediately after the intervention and to 80.61 ± 9.90 at the two-month follow-up. In contrast, the control group showed no significant improvement. Additionally, state anxiety significantly decreased in the intervention group from 51.64 ± 14.97 to 40.20 ± 11.70 at the follow-up, and trait anxiety scores in the intervention group decreased significantly from 49.91 ± 14.96 to 39.82 ± 10.28 at the follow-up, whereas the scores of the control group worsened.

CONCLUSION

The intervention improved quality of life and reduced anxiety in patients with gynecological cancers. Given the scant attention given to mobile application-based follow-up in gynecologic cancer patients in previous studies, this approach can be incorporated into routine care to support patients, and it is recommended for nurses, health care providers, and physicians.

The study was registered as a randomized controlled trial in the Clinical Trial Registration Center of Iran. Registration Date: 2024-02-14, Registration Number: IRCT20231107059977N1.

An online peer support program to improve mental health among university students: A randomized controlled trial

Despite recent calls for more peer support initiatives aimed at promoting mental health in postsecondary institutions, those initiatives remain scarce. In this study, a multisite randomized controlled trial was designed to assess the effect of an online peer support intervention based on acceptance and commitment therapy using mental health and school indicators. Undergraduate students were recruited in three Canadian universities and randomly assigned to an intervention (n = 54) or a wait-list control group (n = 53). Compared to control participants, those who took part in the program self-reported reduced psychological inflexibility, stress, anxiety and depression, and increased psychological flexibility and well-being. The intervention had no effect on academic satisfaction and engagement. These results were found both in completer and intent-to-treat samples. The findings provide evidence that peer support may be a beneficial adjunct to mental health interventions offered to college and university students.

Effects of a nurse-led aftercare telehealth programme on sleep and psychological outcomes of adult burn survivors: A randomized controlled trial

INTRODUCTION

Burn survivors often experience a plethora of post-burn residual needs following their discharge including psychological issues and poor sleep. These needs are often overlooked with a significant focus on resolving physical issues. Aftercare support is particularly limited. The emergence of the Coronavirus pandemic worsened the situation as burn survivors were unable to return to utilise available services outpatient basis. Thus, an innovative nurse-led aftercare programme was developed and delivered via WeChat social medial platform. The current study sought to examine the effects of the intervention on anxiety, depression, and sleep pattern among adult burn survivors.

METHODS

This is a randomised controlled trial. Sixty adult burn survivors were randomly assigned to intervention and control groups. Participants in the intervention group received the nurse-led aftercare programme which involved pre-discharge support and active follow-up on WeChat over an 8-week period and an additional 4 weeks to examine the sustained effects of the intervention. Data were collected at three timepoints: baseline (T0), post-intervention (T1), and follow-up (T2). Generalised estimating equation was employed to ascertain the group, time, and interaction effects.

RESULTS

Using Bonferroni corrected p value (0.017), Anxiety and depression improved at T1 and sustained at T2 with mean scores demonstrating a reduction in both variables and total score. No statistically significant improvement was however observed regarding sleep.

CONCLUSION

Continuous, comprehensive support is required by burn survivors following discharge to improve psychological outcomes. Delivering aftercare via WeChat should be considered a feasible option to supporting burn survivors following discharge.

Genicular artery embolisation versus sham embolisation for symptomatic osteoarthritis of the knee: a randomised controlled trial

OBJECTIVE

To determine the efficacy of genicular artery embolisation (GAE) compared with sham GAE for pain reduction in patients with symptomatic mild-to-moderate knee osteoarthritis (KOA).

DESIGN

Double-blind randomised sham-controlled clinical trial conducted from June 2019 to December 2021. The follow-up period was 4 months.

SETTING

Single-centre study conducted at a university medical centre in Rotterdam, Netherlands.

PARTICIPANTS

58 adults with symptomatic mild-to-moderate KOA not improving with conservative treatment.

INTERVENTIONS

Participants were randomised to receive either GAE treatment or a sham GAE treatment.

MAIN OUTCOME MEASURES

The primary outcome was reduction of pain measured with the Knee Injury and Osteoarthritis Outcome Score pain subscale (0-100, with 0 representing the worst pain outcome and 100 the best) after 4 months. Outcomes were assessed at baseline and 1 and 4 months.

RESULTS

From June 2019 to December 2021, 58 patients were included. 29 patients were randomised to the GAE group and 29 to the sham group. All participants completed the study. The mean pain reduction after 4 months was 21.4 (95% CI 13.9 to 28.8) for the GAE group and 18.4 points (95% CI 11.6 to 25.1) for the sham group. The between-group difference for the mean pain reduction was 3.0 (95% CI -7.1 to 13.0) with an estimated Cohen's d effect size of d = 0.15 (95% CI -0.37 to 0.66). Group allocation was not a significant contributor to pain reduction (p = 0.31). No serious adverse events (AEs) occurred. 23 mild AEs occurred in the GAE group and 5 in the sham group.

CONCLUSION

We did not establish a clinical effect of GAE in patients with mild-to-moderate KOA as GAE produced a similar effect on pain reduction as a sham GAE procedure.

Effects of shuttle balance exercises on gait speed, postural control, and quality of life in older males: A randomized controlled trial

BACKGROUND AND PURPOSE

Enhancing physical function and quality of life in older adults at higher risk of falls is challenging because of the lack of established interventions. This study examines the impact of a 6-week balance training program using the shuttle balance device on gait speed, postural control, and quality of life in older men.

METHODS

This single-blinded randomized controlled trial was conducted in a research laboratory. Thirty-two participants aged ≥60 years were randomly assigned to either an experimental group (EG; n = 16) or a control group (CG; n = 14). The EG participated in a 6-week shuttle balance exercise program, while the CG maintained regular physical activity routines. The main outcome measures included gait speed (assessed via the timed up and go test), postural control (assessed via center of pressure data on a force plate), and quality of life (evaluated using the SF-36 questionnaire).

RESULTS

Post-intervention, the EG showed significant improvements compared with the CG (p < 0.05). The 95% confidence intervals for the differences between groups were as follows: closed eyes (CE) mean velocity (-39.07, -0.13), CE sway area (-48.86, -0.18), SF-36 total score (9.01, 16.81), SF-36 physical functioning (7.00, 24.81), SF-36 physical role functioning (1.80, 27.57), SF-36 pain (15.01, 36.82), SF-36 general health state (7.48, 26.08), SF-36 vitality (5.60, 28.35), and SF-36 mental health (0.21, 21.12).

DISCUSSION

A 6-week shuttle balance training program significantly improves postural control and quality of life in older males. These findings suggest the potential effectiveness of shuttle balance exercises in enhancing physical function and well-being in this population. Further research is needed to validate these findings and explore the long-term effects with larger sample sizes.

Sleeping for two: A randomized controlled trial of cognitive behavioural therapy for insomnia (CBTI) delivered in pregnancy and secondary impacts on symptoms of postpartum depression

BACKGROUND

Insomnia in pregnancy is common and highly comorbid with depression.

OBJECTIVE

To investigate if: 1) depressive symptoms decrease after cognitive behavioural therapy for insomnia (CBTI) delivered in pregnancy, and 2) changes in insomnia symptoms represent a mechanism linking CBT-I treatment and reduced symptoms of postpartum depression.

METHODS

A two-arm, single-blind, parallel groups randomized controlled trial (RCT) design was used to evaluate the impact of a 5-week CBT-I intervention adapted for pregnant people with insomnia (N = 62). Participants were eligible if they were pregnant, between 12 and 28 weeks gestation, and met diagnostic criteria for insomnia. Participants completed questionnaires assessing symptoms of insomnia and depression pre-intervention (T1), post-intervention (T2), and six months postpartum (T3). A path analysis model was used to test direct and indirect effects simultaneously.

RESULTS

There was a significant direct effect of CBT-I on postpartum depressive symptoms at T3. Additionally, significant indirect treatment effects on depressive symptoms at T3 emerged, through depressive symptoms at T2 and through improvements in insomnia that persisted from T2 to T3.

LIMITATIONS

Limitations to the current study include limited generalizability, the non-depressed sample, and variability in treatment and assessment delivery (in-person vs. online).

CONCLUSIONS

CBT-I treatment in pregnancy may indirectly reduce postpartum depressive symptoms, through sustained improvements in insomnia symptoms.
