Colonoscopy Preparation

Abstract Background Mobile health technologies are innovative solutions for delivering instructions to patients preparing for their colonoscopy appointments. Aims To systematically review the literature of the effect of smartphone-based technologies supporting colonoscopy appointment preparation on patient outcomes. Methods With the assistance of a librarian, one author searched MEDLINE, EMBASE, CINAHL and CENTRAL for randomized controlled trials (RCTs) that evaluated the effect of smartphone-based technologies for colonoscopy preparation on bowel cleanliness and user satisfaction. Two independent reviewers extracted data on patient and intervention characteristics and study outcomes, and appraised study quality using the Cochrane Risk-of-Bias tool. Summary statistics were generated using random effects models for the trials that used either the Boston Bowel Preparation Scale (BPPS) or the Ottawa Bowel Preparation Scale (OBPS). Statistical heterogeneity was assessed using I2. Results Ten RCTs met our inclusion criteria. Smartphone-based interventions included apps, SMS text messages, video clips, camera apps, and social media apps. Most studies showed smartphone-based interventions were associated with better quality bowel cleanliness scores and higher user satisfaction compared to usual care. Standardized mean differences for the BBPS and OBPS differed between the intervention and control groups [SMD 0.57, 95%CI 0.18, 0.95] and [SMD -0.39, 95%CI -0.59, -0.19], respectively. Statistically significant statistical heterogeneity was found for the meta-analyses for the trials employing the BBPS (I2=80%, p=0.03) but not for the trials using the OBPS (I2=45%, p=0.16). All RCTs were at high risk of bias from non-blinded participants, and most studies were at high or unclear risk of bias due to lack of allocation concealment. Funnel plots to evaluate publication bias were not generated as there were too few studies with sufficient data to analyze. Conclusions This systematic review found that smartphone-based technology users had better bowel cleanliness quality scores and higher satisfaction with the method of delivering instructions compared to patients given usual care. Given that all RCTs were at high risk of bias, high-quality RCTs that blind participants and conceal study group allocation are needed.

Background Mobile health (mHealth) technologies are innovative solutions for delivering instructions to patients preparing for colonoscopy. Objective To systematically review the literature evaluating the effectiveness of mHealth technologies supporting colonoscopy preparation on patient and clinical outcomes. Methods MEDLINE, EMBASE, CINAHL and CENTRAL were searched for randomized controlled trials (RCTs) that evaluated the effectiveness of mHealth technologies for colonoscopy preparation on patient and clinical outcomes. Two reviewers independently assessed study eligibility, extracted data, and appraised methodological quality using the Cochrane Risk-of-Bias tool. Data were pooled using random effects models and when heterogeneity, assessed using I2, was statistically significant, a qualitative synthesis of the data was performed. Publication bias was assessed using a funnel plot. Results Ten RCTs (3,383 participants) met inclusion criteria. MHealth interventions included smartphone apps, SMS text messages, videos, camera apps, and a social media app. Outcomes were bowel cleanliness quality, user satisfaction, colonoscopy quality indicators (cecal intubation time, withdrawal time, adenoma detection rate), adherence to diet, and cancellation/no-show rates. MHealth interventions were associated with better bowel cleanliness scores on the Boston Bowel Preparation Scale [standardized mean difference (SMD) 0.57, 95%CI 0.37–0.77, I2 = 60%, p = 0.08] and the Ottawa Bowel Preparation Scale [SMD -0.39, 95%CI -0.59–0.19, I2 = 45%, p = 0.16], but they were not associated with rates of willingness to repeat the colonoscopy using the same regimen [odds ratio (OR) 1.88, 95%CI 0.85–4.15, I2 = 48%, p = 0.12] or cancellations/no-shows [OR 0.96, 95%CI 0.68–1.35, I2 = 0%]. Most studies showed that adequate bowel preparation, user satisfaction and adherence to diet were better in the intervention groups compared to the control groups, while inconsistent findings were observed for the colonoscopy quality indicators. All trials were at high risk of bias for lack of participant blinding. Visual inspection of a funnel plot revealed publication bias. Conclusions MHealth technologies show promise as a way to improve bowel cleanliness, but trials to date were of low methodological quality. High-quality research is required to understand the effectiveness of mHealth technologies on colonoscopy outcomes.

The role of adjuvant transarterial chemoembolization (TACE) for patients with resectable hepatocellular carcinoma (HCC) undergoing hepatectomy is currently unclear. We performed a systematic review of the literature using the MEDLINE, Embase, and Cochrane Library databases. Random-effects meta-analysis was carried out to compare the overall survival (OS) and recurrence-free survival (RFS) of patients with resectable HCC undergoing hepatectomy followed by adjuvant TACE vs. hepatectomy alone in randomized controlled trials (RCTs). The risk of bias was assessed using the Risk of Bias 2.0 tool. Meta-regression analyses were performed to explore the effect of hepatitis B viral status, microvascular invasion, type of resection (anatomic vs. parenchymal-sparing), and tumor size on the outcomes. Ten eligible RCTs, reporting on 1216 patients in total, were identified. The combination of hepatectomy and adjuvant TACE was associated with superior OS (hazard ratio (HR): 0.66, 95% confidence interval (CI): 0.52 to 0.85; p < 0.001) and RFS (HR: 0.70, 95% CI: 0.56 to 0.88; p < 0.001) compared to hepatectomy alone. There were significant concerns regarding the risk of bias in most of the included studies. Overall, adjuvant TACE may be associated with an oncologic benefit in select HCC patients. However, the applicability of these findings may be limited to Eastern Asian populations, due to the geographically restricted sample. High-quality multinational RCTs, as well as predictive tools to optimize patient selection, are necessary before adjuvant TACE can be routinely implemented into standard practice.

Abstract Background Approximately half of patients with ST-segment elevation myocardial infarction (STEMI) present with multivessel coronary artery disease (CAD) during primary percutaneous coronary intervention (PCI). Purpose To compare the risks of major cardiovascular outcomes and procedural complications in patients with STEMI and multivessel CAD randomized to complete revascularization versus culprit-only PCI. Methods We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing complete to culprit-only PCI, identified via a systematic search of MEDLINE, Embase, and the Cochrane Libraries. Count data were pooled using DerSimonian and Laird random-effects models with inverse variance weighting to obtain relative risks (RRs) and corresponding 95% confidence intervals (CIs). Results A total of 8 RCTs (n=6,632) were included, with mean/median follow-up times ranging from 6 to 36 months. Compared to culprit-only PCI, complete PCI was associated with a substantial reduction in MACE (12.6% vs. 22.0%), repeat myocardial infarction (4.5% vs. 6.9%), and repeat revascularization (3.3% vs. 12.1%) (Table 1). Complete PCI may also improve all-cause and cardiovascular mortality, but estimates were accompanied by wide 95% CIs. Findings for stroke, major bleeding, and contrast-induced AKI were inconclusive. Conclusion Complete revascularization appears to confer benefit over culprit-only PCI in patients with STEMI and multivessel CAD, and should be considered a first-line strategy in these patients.

Cancer Related Fatigue

Objective. Cancer-related fatigue (CRF) is the most common and devastating problem in cancer patients even after successful treatment. This study aimed to determine the effects of supervised multimodal exercise interventions on cancer-related fatigue through a systematic review and meta-analysis.Design. A systematic review was conducted to determine the effectiveness of multimodal exercise interventions on CRF. Databases of PubMed, CENTRAL, EMBASE, and OVID were searched between January and March 2014 to retrieve randomized controlled trials. Risk of bias was evaluated using the PEDro scale.Results. Nine studiesn=772were included in both systematic review and meta-analysis. Multimodal interventions including aerobic exercise, resistance training, and stretching improved CRF symptoms (SMD=-0.23; 95% CI: −0.37 to −0.09;P=0.001). These effects were also significant in patients undergoing chemotherapyP<0.0001. Nonsignificant differences were found for resistance training interventionsP=0.30. Slight evidence of publication bias was observedP=0.04. The studies had a low risk of bias (PEDro scale mean score of 6.4 (standard deviation (SD) ± 1.0)).Conclusion. Supervised multimodal exercise interventions including aerobic, resistance, and stretching exercises are effective in controlling CRF. These findings suggest that these exercise protocols should be included as a crucial part of the rehabilitation programs for cancer survivors and patients during anticancer treatments.

Introduction: Meibomian Gland Dysfunction (MGD) is a common, often overlooked, chronic condition affecting eyes for which various therapies are being evaluated. Considering the absence of a systematic review and meta-analysis, the present review was carried out. Methods: An appropriate search strategy eligibility criteria were framed and electronic databases were scrutinized for appropriate literature. Randomized Controlled Trials (RCTs) enrolling patients diagnosed with MGD were included. Outcome measures were Tear Break Up Time (TBUT), Schirmer’s test, Meibomian Gland (MG) secretion score, MG plugging score, OSDI and SPEED. Cochrane’s tool was used to assess the risk of bias and Forest plot were generated either with fixed or random effects model, with Standardized Mean Difference (SMD). Results: TBUTs, Schirmer’s test and OSDI scores for systemic antimicrobials with placebo were 1.58 [1.33, 1.83], 2.93 [0.78, 5.09] and -3.58 [-4.28, -2.89] respectively. No quantitative synthesis was attempted for either mebiomian plugging or meibomian secretion scores and no significant changes were observed with any other outcome parameter. Conclusion: Only the systemic antimicrobials were found to improve the clinical features of meibomian gland dysfunction. Varying effects of different therapeutic agents (heat therapies, omega-3-fatty acids and castor oil) were identified for MGD but the risk of bias pertaining to randomization and allocation concealment was found to be associated with most of the current RCTs. More high quality evidence is required to confirm the findings of the present review.

BackgroundApproximately 15 to 30% of children and adolescents suffer from daily pain persistent over more than 3 months and there is evidence supporting that the prevalence of chronic pain is steadily increasing in this population. Chronic pain is known to have a negative impact on children's development and social behaviour, leading often to severe psychological distress and physical disability. We reviewed medical literature to assess the characteristics and quality of randomized controlled trials (RCTs) on pharmacological and non-pharmacological therapies in chronic and recurrent pain in the paediatric population.MethodsWe performed a systematic search of PubMed, Embase and the Cochrane Library up to March 2014. Bibliographies of relevant articles were also hand-searched. We included all RCTs that involved children and adolescents (age 0 to 18 years) and evaluated the use of a pharmacological agent or a non-pharmacological approach in the context of chronic or recurrent pain. The latter was defined as pain persisting for more than 3 months. Methodological quality was evaluated using the Cochrane Risk of Bias Tool. Two reviewers independently assessed studies for inclusion and evaluated methodological quality.ResultsA total of 52 randomized controlled trials were selected and included in the analysis. The majority were conducted in single hospital institutions, with no information on study funding. Median sample size was 45 (34–57) participants. Almost 50% of the RCTs included both adults and children with a median age at inclusion of 13 years. Non-pharmacological approaches were more commonly tested whereas evaluation of pharmacological agents concerned less than 30% of RCTs. Abdominal pain and headache were the most common types of chronic pain experienced among trial participants. Overall, the methodological quality was poor and did not parallel the number of RCTs that increased over the years. The risk of bias was high or unclear in 70% of the trials.ConclusionsThis is the first systematic review of RCTs conducted to evaluate pharmacological and non-pharmacological therapies in chronic and recurrent pain in children and adolescents. Although, management of pain in adults has significantly improved over the years due to the evaluation of numerous analgesic therapies, our results highlight the existing knowledge gap with regards to children and adolescents. Therapeutic strategies, in particular pharmacological agents, applied to relieve chronic or recurrent pain in children and adolescents are not evaluated through high quality RCTs. The need to improve analgesic therapy in children and adolescents with chronic pain is still unmet. We discuss possible research constraints and challenges related to this fact as well as adequate methodologies to circumvent them.

BACKGROUND Psychiatric disorders often have an onset at an early age, and early identification and intervention help improve prognosis. A fine-grained, unobtrusive, and effective way to monitor symptoms and level of function could help distinguish severe psychiatric health problems from normal behavior and potentially lead to a more efficient use of clinical resources in the current health care system. The use of smartphones to monitor and treat children, adolescents, and young adults with psychiatric disorders has been widely investigated. However, no systematic review concerning smartphone-based monitoring and treatment in this population has been published. OBJECTIVE This systematic review aims at describing the following 4 features of the eligible studies: (1) monitoring features such as self-assessment and automatically generated data, (2) treatment delivered by the app, (3) adherence to self-monitoring, and (4) results of the individual studies. METHODS We conducted a systematic literature search of the PubMed, Embase, and PsycInfo databases. We searched for studies that (1) included a smartphone app to collect self-monitoring data, a smartphone app to collect automatically generated smartphone-based data, or a smartphone-based system for treatment; (2) had participants who were diagnosed with psychiatric disorders or received treatment for a psychiatric disorder, which was verified by an external clinician; (3) had participants who were younger than 25 years; and (4) were published in a peer-reviewed journal. This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The risk of bias in each individual study was systematically assessed. RESULTS A total of 2546 unique studies were identified through literature search; 15 of these fulfilled the criteria for inclusion. These studies covered 8 different diagnostic groups: psychosis, eating disorders, depression, autism, self-harm, anxiety, substance abuse, and suicidal behavior. Smartphone-based self-monitoring was used in all but 1 study, and 11 of them reported on the participants’ adherence to self-monitoring. Most studies were feasibility/pilot studies, and all studies on feasibility reported positive attitudes toward the use of smartphones for self-monitoring. In 2 studies, automatically generated data were collected. Three studies were randomized controlled trials investigating the effectiveness of smartphone-based monitoring and treatment, with 2 of these showing a positive treatment effect. In 2 randomized controlled trials, the researchers were blinded for randomization, but the participants were not blinded in any of the studies. All studies were determined to be at high risk of bias in several areas. CONCLUSIONS Smartphones hold great potential as a modern, widely available technology platform to help diagnose, monitor, and treat psychiatric disorders in children and adolescents. However, a higher level of homogeneity and rigor among studies regarding their methodology and reporting of adherence would facilitate future reviews and meta-analyses.

ABSTRACT Background Loss of skeletal muscle mass and muscle weakness are common in a variety of clinical conditions with both wasting and weakness associated with an impairment of physical function. β-Hydroxy-β-methylbutyrate (HMB) is a nutrition supplement that has been shown to favorably influence muscle protein turnover and thus potentially plays a role in ameliorating skeletal muscle wasting and weakness. Objectives The aim of this study was to investigate the efficacy of HMB alone, or supplements containing HMB, on skeletal muscle mass and physical function in a variety of clinical conditions characterized by loss of skeletal muscle mass and weakness. Methods A systematic review and meta-analysis of randomized controlled trials reporting outcomes of muscle mass, strength, and physical function was performed. Two reviewers independently performed screening, data extraction, and risk-of-bias assessment. Outcome data were synthesized through meta-analysis with the use of a random-effects model and data presented as standardized mean differences (SMDs). Results Fifteen randomized controlled trials were included, involving 2137 patients. Meta-analysis revealed some evidence to support the effect of HMB alone, or supplements containing HMB, on increasing skeletal muscle mass (SMD = 0.25; 95% CI: –0.00, 0.50; z = 1.93; P = 0.05; I2 = 58%) and strong evidence to support improving muscle strength (SMD = 0.31; 95% CI: 0.12, 0.50; z = 3.25; P = 0.001; I2 = 0%). Effect sizes were small. No effect on bodyweight (SMD = 0.16; 95% CI: –0.08, 0.41; z = 1.34; P = 0.18; I2 = 67%) or any other outcome was found. No study was considered to have low risk of bias in all categories. Conclusion HMB, and supplements containing HMB, increased muscle mass and strength in a variety of clinical conditions, although the effect size was small. Given the bias associated with many of the included studies, further high-quality studies should be undertaken to enable interpretation and translation into clinical practice. The trial was registered on PROSPERO as CRD42017058517.

ABSTRACT Background Clinical trials evaluating the effect of calcium supplementation on bone loss in lactating women have been small, with inconsistent results. Objectives We aimed to determine the effect of calcium supplementation on bone mineral density (BMD) in lactating women. Methods An electronic search of databases was conducted from inception to January 2020. Two authors screened studies, extracted data, and assessed the risk of bias of eligible studies. Percentage change in BMD was pooled using random-effects models and reported as weighted mean differences (WMDs) with 95% CIs. Risk of bias was assessed using the Cochrane risk of bias tool. Results Five randomized controlled trials including 567 lactating women were included. All had a high risk of bias. Mean baseline calcium intake ranged from 562 to 1333 mg/d. Compared with control groups (placebo/no intervention), calcium supplementation (600/1000 mg/d) had no significant effect on BMD at the lumbar spine (WMD: 0.74%; 95% CI: −0.10%, 1.59%; I2 = 47%; 95% CI: 0%, 81%; n = 527 from 5 trials) or the forearm (WMD: 0.53%; 95% CI: −0.35%, 1.42%; I2 = 55%; 95% CI: 0%, 85%; n = 415 from 4 trials). BMD at other sites was assessed in single trials: calcium supplementation had a small to moderate effect on total-hip BMD (WMD: 3.3%; 95% CI: 1.5%, 5.1%) but no effect on total body or femoral neck BMD. Conclusions Overall, the meta-analysis indicates that calcium supplementation does not provide clinically important benefits for BMD in lactating women. However, there was adequate dietary intake before supplementation in some studies, and others did not measure baseline calcium intake. Advising lactating women to meet the current recommended calcium intakes (with supplementation if dietary intake is low) is warranted unless new high-certainty evidence to the contrary from robust clinical trials becomes available. More research needs to be done in larger samples of women from diverse ethnic and racial groups. This systematic review was registered at www.crd.york.ac.uk/prospero as CRD42015022092.

Abstract Introduction Sepsis and septic shock are leading causes of ICU mortality. They are characterized by excessive host inflammation, upregulation of procoagulant proteins and depletion of natural anticoagulants. Therapeutic apheresis has the potential to improve survival in sepsis by removing injurious elements and inflammatory cytokines and restoring deficient plasma proteins. The objective of our systematic review was to evaluate the efficacy and safety of apheresis in patients with sepsis or septic shock. Methods We searched PubMed, EMBASE, and CENTRAL (from inception to February 2013), the International Clinical Trials Registry Platform, relevant conference proceedings and bibliographies of pertinent reviews and included clinical trials. Two reviewers independently identified randomized controlled trials of patients diagnosed with sepsis, severe sepsis, septic shock or disseminated intravascular coagulation due to infection who received plasmapheresis, plasma exchange, or plasma filtration compared to placebo or usual care. Two reviewers independently extracted trial-level data including population characteristics, interventions, outcomes, and funding sources. We assessed risk of bias using the Cochrane risk of bias tool. Our primary outcome was all-cause mortality reported at the longest follow-up. Secondary outcomes were hospital and ICU lengths of stay, and reported adverse events. We expressed summary effect measures as odds ratios (OR) with 95% confidence intervals (CI). Random effect models using the Mantel-Haenszel method were used for pooled analyses. Results We identified 1771 potential citations of which 3 trials (144 patients) met inclusion criteria. The mean age of patients ranged from 38 to 53 years in the two adult trials and 1 to 18 years in the single pediatric trial. The mean APACHE score was 25.2 (APACHE II) in one study and 54.9 (APACHE III) in the other study reporting illness severity scores. All 3 studies were adjudicated to be unclear or high risk of bias. We observed that the use of apheresis was not associated with a significant reduction in all cause mortality (OR 0.42, 95% CI 0.16 - 1.12, I2=30%) (see Figure). In a subgroup analysis of studies including children exclusively, we observed that apheresis was associated with a significant reduction in mortality (OR 0.03, 95% CI 0.00 – 0.94). None of the included studies reported ICU or hospital length of stay. Only one study reported adverse events associated with apheresis including 6 episodes of hypotension and one allergic reaction to fresh frozen plasma. Central-venous catheter related complications were not reported. Conclusions In patients with sepsis or septic shock, apheresis is not associated a significant reduction in all cause mortality. There is currently insufficient evidence to recommend apheresis as an adjunctive therapy in patients with sepsis or septic shock. Rigorous randomized controlled trials powered to detect differences in patient-centered, clinically relevant outcomes are required to evaluate the impact of apheresis in this patient population.
