Non-invasive techniques for stimulating urine production in non-toilet trained children: a systematic review

BackgroundUrinary tract infection requires collection of a sterile urine specimen for diagnosis, which is difficult and time consuming in pre-continent children. This systematic review summarises evidence of the effectiveness of bladder stimulation techniques on urine collection in pre-continent children, compared with standard techniques.MethodsMEDLINE, PubMed, EMBASE and CINAHL were searched to May 2019. Selection, data extraction, risk of bias and quality assessment were undertaken by two independent reviewers. Inclusion: (1) all study designs; (2) pre-continent, age <3 years receiving bladder stimulation techniques; (3) outcomes including time to urine collection or contamination rates; (4) English-language articles. Exclusion: coexisting neurological disorders.ResultsThree randomised controlled trials (RCTs) were identified using three techniques in 568 participants aged 1 day to 35 months. Two RCTs demonstrated an increased success in voiding within 5 min, one using a finger tapping and lumbar paravertebral massage technique and the other cold saline-soaked gauze rubbed over the suprapubic region, compared with no active intervention. A third RCT using a mechanical vibration device demonstrated no difference in time to voiding from advice alone. Non-randomised studies compared different temperatures for the gauze intervention and tapping alone versus urine bags. Six uncontrolled studies tested the finger tapping and massage technique. Risk of bias was low for one RCT and unclear for two RCTs with the other studies rated poor to fair quality. Overall, the evidence on success rates was graded low for tapping plus massage and moderate for the gauze rubbing intervention. Adverse effects included crying and mild distress.DiscussionThe results suggest a positive effect of stimulation techniquesbut lack of replication in rigorous RCTs and heterogeneity of techniques and outcomes assessed prevent conclusive recommendations being made. Further RCTs are required comparing non-invasive stimulation methods and assessing time to successful collection, contamination rates, adverse effects, caregiver and clinical staff acceptability.

A broad spectrum of novel targeted therapies with prime antitumor activity and/or ample control of hormonal symptoms together with an overall acceptable safety profile have emerged for patients with metastatic neuroendocrine neoplasms (NENs). In this systematic review and quantitative meta-analysis, the PubMed, EMBASE, Cochrane Central Register of Controlled Trials and clinicaltrials.gov databases were searched to assess and compare the safety profile of NEN treatments with special focus on the cardiovascular adverse effects of biotherapy and molecular targeted therapies (MTTs). Quality/risk of bias were assessed using GRADE criteria. Placebo-controlled randomized clinical trials (RCTs) in patients with metastatic NENs, including medullary thyroid cancer (MTC) were included. A total of 3695 articles and 122 clinical trials registered in clinicaltrials.gov were screened. We included sixteen relevant RCTs comprising 3408 unique patients assigned to different treatments compared with placebo. All the included studies had a low risk of bias. We identified four drug therapies for NENs with eligible placebo-controlled RCTs: somatostatin analogs (SSAs), tryptophan hydroxylase (TPH) inhibitors, mTOR inhibitors and tyrosine kinase inhibitors (TKI). Grade 3 and 4 adverse effects (AE) were more often encountered in patients treated with mTOR inhibitors and TKI (odds ratio [OR]: 2.42, 95% CI: 1.87–3.12 and OR: 3.41, 95% CI: 1.46–7.96, respectively) as compared to SSAs (OR:0.77, 95% CI: 0.47–1.27) and TPH inhibitors (OR:0.77, 95% CI: 0.35–1.69). MTOR inhibitors had the highest risk for serious cardiac AE (OR:3.28, 95% CI: 1.66–6.48) followed by TKIs (OR:1.51, 95% CI: 0.59–3.83). Serious vascular AE were more often encountered in NEN patients treated with mTOR inhibitors (OR: 1.72, 95% CI: 0.64–4.64) and TKIs (OR:1.64, 95% CI: 0.35–7.78). Finally, patients on TKIs were at higher risk for new-onset or exacerbation of pre-existing hypertension (OR:3.31, 95% CI: 1.87–5.86). In conclusion, SSAs and TPH inhibitors appear to be safer as compared to mTOR inhibitors and TKIs with regards to their overall toxicity profile, and cardiovascular toxicities in particular. Special consideration should be given to a patient-tailored approach with anticipated toxicities of targeted NEN treatments together with assessment of cardiovascular comorbidities, assisting clinicians in treatment selection and early recognition/management of cardiovascular toxicities. This approach could improve patient compliance and preserve cardiovascular health and overall quality of life.

Abstract Background Behaviour change techniques (BCTs) employed within PA intervention for pregnant women with a healthy body mass index (BMI) have been previously identified, however, these BCTS may differ for other weight profiles during pregnancy. The aim of this current review was to identify and summarise the evidence for effectiveness of PA interventions on PA levels for pregnant women with overweight and obesity, with an emphasis on the BCTs employed. Methods A systematic review and meta-analysis of PA intervention studies using the PRISMA statement was conducted. Searches were conducted of eight databases in January 2019. Strict inclusion/exclusion criteria were employed. The validity of each included study was assessed using the Cochrane Collaboration’s tool for assessing risk of bias. The primary outcome measure was change in PA levels, subjectively or objectively measured, with physical fitness as a secondary outcome. All intervention descriptions were double coded by two authors using Michie’s et al’s BCT taxonomy V1. Meta-analyses using random effect models assessed the intervention effects on PA. Other PA outcomes were summarised in a narrative synthesis. Results From 8389 studies, 19 met the inclusion criteria 13 of which were suitable for inclusion in a meta-analysis. The remaining 6 studies were described narratively due to insufficient data and different outcome measures reported. In the meta-analysis, comparing interventions to a control group, significant increases were found in the intervention group for metabolic equivalent (SMD 0.39 [0.14, 0.64], Z = 3.08 P = 0.002) and physical fitness (VO2 max) (SMD 0.55 [0.34, 0.75], Z = 5.20 P = < 0.001). Of the other six, five studies reported an increase in PA for the intervention group versus the control with the other study reporting a significant decrease for women in their 3rd trimester (p = 0.002). ‘Self-monitoring of behaviour’ was the most frequently used BCTs (76.5%), with ‘social support’ being newly identified for this pregnant population with overweight or obesity. Conclusions This review identified a slight increase in PA for pregnant women with overweight and obesity participating in interventions. However, due to the high risk of bias of the included studies, the results should be interpreted with caution. PA measures should be carefully selected so that studies can be meaningfully compared and standardised taxonomies should be used so that BCTs can be accurately assessed.

Background. Insomnia is a prominent complaint of cancer patients that can significantly affect their quality of life and symptoms related to sleep quality. Conventional drug approaches have a low rate of success in alleviating those suffering insomnia. The aim of this systematic review was to assess the efficacy of acupuncture in the management of cancer-related insomnia. Methods. A total of 12 databases were searched from their inception through January 2016 without language restriction. Randomized controlled trials (RCTs) and quasi-RCTs were included if acupuncture was used as the sole intervention or as an adjunct to another standard treatment for any cancer-related insomnia. The data extraction and the risk of bias assessments were performed by 2 independent reviewers. Results. Of the 90 studies screened, 6 RCTs were included. The risk of bias was generally unclear or low. Three RCTs showed equivalent effects on the Pittsburgh Sleep Quality Index and 2 RCTs showed the similar effects on response rate to those of conventional drugs at the end of treatment. The other RCT showed acupuncture was better than hormone therapy in the numbers of hours slept each night and number of times woken up each night. The 3 weeks of follow-up in 2 RCTs showed superior effects of acupuncture compared with conventional drugs, and a meta-analysis showed significant effects of acupuncture. Two RCTs tested the effects of acupuncture on cancer-related insomnia compared with sham acupuncture. One RCT showed favourable effects, while the other trial failed to do so. Conclusion. There is a low level of evidence that acupuncture may be superior to sham acupuncture, drugs or hormones therapy. However, the number of studies and effect size are small for clinical significance. Further clinical trials are warranted.

Background: Some Network Meta-analysis (NMA) has been published regarding atopic dermatitis (AD). These studies have considered drugs under investigation both in monotheraphy or in combination with topical corticosteroids, as well as systemic immunosuppressant therapies. The objective of this study is to evaluate the efficacy and safety of biological agents and small molecules in AD. Methods: A systematic review and NMA of biologics agents and small molecules in AD was performed. A literature search was performed using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for clinical trials and systematic reviews between January 2000 and 19 December 2020. Only randomized clinical trials (RCTs) were included. It was limited to English language and adult human subjects. Two networks were evaluated: monotherapy and combination with TCS. The two primary outcomes were Eczema Area and Severity Index (EASI) 75 and EASI 90 change from baseline to week 12–16, depending on source study cut-off. The Cochrane’s Risk of Bias tool 2011 update was used to analyze the risk of bias, focused on the primary objectives. Results: 30 RCTs (included in 26 publications) were included in the systematic review. Finally, 23 RCTs were included in the quantitative analysis (14 RCTs including 3582 patients in monotherapy; and 9 RCTs including 3686 patients with TCS). In monotherapy, a higher percentage of patients achieving EASI-75 was obtained with Upadacitinib 30 mg [OR: 18.90 (13.94; 25.62)] followed by Abrocitinib 200 mg [OR = 11.26 (7.02; 18.05)] and Upadacitinib 15 mg [OR: 10.89 (8.13; 14.59)]. These results were also observed in studies where the use of topical corticosteroid (TCS) was allowed (OR Upadacitinib 30 mg = 9.43; OR Abrocitinib 200 mg = 6.12; OR Upadacitinib 15 mg = 5.20). Regarding IGA, the percentage of patients achieving IGA0/1 was higher with both doses of Upadacitinib 30 mg [OR: 19.13 (13.14; 27.85)] and 15 mg [OR = 10.95 (7.52; 15.94). In studies where the use of TCS were allowed, however, the dose of Abrocitinib 200 mg [OR = 6.10 (3.94; 9.44)] showed higher efficacy than Upadacitinib 15 mg [OR = 5.47 (3.57; 8.41)]. Regarding safety, the drugs with the highest probability of presenting adverse effects were the Janus kinases (JAK) inhibitors, Upadacitinib and Abrocitinib in monotherapy and Baricitinib in combination with TCS. Discussion: Some risks of bias have been found, which must be taken into account when interpreting the results. The funnel plot shows a possible publication bias that may underestimate the efficacy of drugs. Upadacitinib and Abrocitinib are the drugs with the highest efficacy, both in monotherapy and in association with TCS. However, they were also those associated with the highest risk of adverse effects, showing monoclonal antibodies better safety profile. Limitations: We have included molecules still in the development phase as well studies completed and presented at conferences and with data available in Trialsgov® but not published yet. Several molecules’ development had included a small number of patients from 12 to 17 years of age, without being able to differentiate the results from the adult population. Other: Founding: None.

Methotrexate (MTX) is a folate analog widely used against a range of diseases including malignancies and autoimmune disorders. Its high effectiveness-price ratio also won extensive application in ophthalmology. On the other hand, although MTX has an excellent pharmacological efficacy, MTX associated side effects in clinical use, which vary from patient to patient, are nonnegligible. There is no comparatively systematic review on MTX associated side effects and its risk factors. This review aimed to reveal novel clinical approaches of MTX and its adverse effects in order to provide a reference for ophthalmic scholars in clinical application of MTX.

ObjectiveVisible differences in appearance are associated with poor social and psychological outcomes. Effectiveness of non-surgical cosmetic and other camouflage interventions is poorly understood. The objective was to evaluate effects of cosmetic and other camouflage interventions on appearance-related outcomes, general psychological outcomes and adverse effects for adults with visible appearance differences.DesignSystematic review.Data sourcesMEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid) CINAHL and Cochrane Central databases searched from inception to 24 October 2020. Two reviewers independently reviewed titles and abstracts and full texts.Eligibility criteriaRandomised controlled trials in any language on non-surgical cosmetic or other camouflage interventions that reported appearance-related outcomes, general psychological outcomes or adverse effects for adults with visible appearance differences.Data extraction and synthesisTwo reviewers independently extracted data, assessed intervention reporting using the Template for Intervention Description and Replication checklist, and assessed risk of bias using the Cochrane risk of bias tool. Outcomes included appearance-related outcomes, general psychological outcomes (eg, depression, anxiety) and adverse effects.ResultsOne head-to-head trial and five trials with waiting list or routine care comparators were included. All had unclear or high risk of bias in at least five of seven domains. Effect sizes could not be determined for most outcomes due to poor reporting. Between-group statistically significant differences were not reported for any appearance-related outcomes and for only 5 of 25 (20%) other psychological outcomes. Given heterogeneity of populations and interventions, poor reporting and high risk of bias, quantitative synthesis was not possible.ConclusionsConclusions about effectiveness of non-surgical cosmetic or other camouflage interventions could not be drawn. Well-designed and conducted trials are needed. Without such evidence, clinicians or other qualified individuals should engage with patients interested in cosmetic interventions in shared decision making, outlining potential benefits and harms, and the lack of evidence to inform decisions.PROSPERO registration numberCRD42018103421.

Fixed Dental Prostheses

Although CAD/CAM ceramics present a promising alternative to metal-ceramic fixed dental prostheses, little is known about their mid- and long-term clinical performance. This systematic review aims to estimate the survival and success rates and describes the underlying complication characteristics for CAD/CAM tooth-supported zirconia- and lithium disilicate-based fixed dental prostheses (FDPs). We systematically searched MEDLINE and Web of Science to find relevant prospective studies with a follow-up of at least one year. We estimated pooled 1-, 5-, and 10-year survival and success rates by combining the collected data in a Poisson regression model. Descriptive statistics were conducted to evaluate the distribution of failures and complications in the included studies. Risk of bias for the included studies was assessed with an adapted checklist for single-arm trials. Pooled estimated 1-, 5-, and 10-year survival rates ranged from 93.80% to 94.66%, 89.67% to 91.1%, and 79.33% to 82.20%, respectively. The corresponding success rates excluding failures, but including any other types of intervention were 94.53% to 96.77%, 90.89% to 94.62%, and 81.78% to 89.25%. Secondary caries was the most frequent cause of failure, followed by chipping of the veneering. The most common cause of complication excluding failures but requiring intervention was chipping of the veneering. Risk of bias was generally acceptable for the included studies, with seven studies associated with low risk of bias, eight studies with a moderate risk of bias, and three studies with serious risk of bias. The current meta-analysis on CAD/CAM-supported FDPs revealed satisfying survival and success rates for up to 10 years of exposure. More prospective studies focusing on long-term performance are needed to strengthen the evidence currently available in the literature.

BACKGROUND Medical schools in low- and middle-income countries are facing a shortage of staff, limited infrastructure, and restricted access to fast and reliable internet. Offline digital education may be an alternative solution for these issues, allowing medical students to learn at their own time and pace, without the need for a network connection. OBJECTIVE The primary objective of this systematic review was to assess the effectiveness of offline digital education compared with traditional learning or a different form of offline digital education such as CD-ROM or PowerPoint presentations in improving knowledge, skills, attitudes, and satisfaction of medical students. The secondary objective was to assess the cost-effectiveness of offline digital education, changes in its accessibility or availability, and its unintended/adverse effects on students. METHODS We carried out a systematic review of the literature by following the Cochrane methodology. We searched seven major electronic databases from January 1990 to August 2017 for randomized controlled trials (RCTs) or cluster RCTs. Two authors independently screened studies, extracted data, and assessed the risk of bias. We assessed the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations criteria. RESULTS We included 36 studies with 3325 medical students, of which 33 were RCTs and three were cluster RCTs. The interventions consisted of software programs, CD-ROMs, PowerPoint presentations, computer-based videos, and other computer-based interventions. The pooled estimate of 19 studies (1717 participants) showed no significant difference between offline digital education and traditional learning groups in terms of students’ postintervention knowledge scores (standardized mean difference=0.11, 95% CI –0.11 to 0.32; small effect size; low-quality evidence). Meta-analysis of four studies found that, compared with traditional learning, offline digital education improved medical students’ postintervention skills (standardized mean difference=1.05, 95% CI 0.15-1.95; large effect size; low-quality evidence). We are uncertain about the effects of offline digital education on students’ attitudes and satisfaction due to missing or incomplete outcome data. Only four studies estimated the costs of offline digital education, and none reported changes in accessibility or availability of such education or in the adverse effects. The risk of bias was predominantly high in more than half of the included studies. The overall quality of the evidence was low (for knowledge, skills, attitudes, and satisfaction) due to the study limitations and inconsistency across the studies. CONCLUSIONS Our findings suggest that offline digital education is as effective as traditional learning in terms of medical students’ knowledge and may be more effective than traditional learning in terms of medical students’ skills. However, there is a need to further investigate students’ attitudes and satisfaction with offline digital education as well as its cost-effectiveness, changes in its accessibility or availability, and any resulting unintended/adverse effects.
