Family Interventions

IntroductionFamily interventions are effective and are strongly recommended for psychotic disorders. However, there is a variety of intervention types, and their differential efficacy is widely unclear. The aim of the planned network meta-analysis (NMA) is to compare the efficacy of family interventions that differ in content (eg, psychoeducation, mutual support, skills training) and format (eg, number of sessions, inclusion of patients, form of delivery).Methods and analysisWe will include randomised controlled trials comparing psychosocial interventions directed at the adult relatives, friends or non-professional carers of people with a diagnosis of a psychotic disorder (schizophrenia spectrum) to any kind of control condition. The main outcomes will be global clinical state for the patients and coping with psychosis as well as attitudes towards psychosis for the relatives. Additional outcomes will be severity of symptoms, functioning, burden and compliance/drop-out. We conducted a comprehensive search of Cochrane Central Register of Controlled Trials, MEDLINE(R), PsycINFO, Cumulative Index to Nursing & Allied Health Literature (8 August 2019) and reference lists of review articles. Full-text assessment of eligibility, data extraction and risk-of-bias assessment will be done by two independent reviewers. An NMA will be conducted for any of the planned outcomes and intervention characteristics for which sufficient and appropriate data are available. The analyses will make use of a random effects model within a frequentist framework. Estimates for all pairwise treatment effects will be obtained using standardised mean differences for continuous outcomes and risk ratios for dichotomous outcomes. Interventions will be ranked according to their relative efficacy. We will address the assumption of transitivity, heterogeneity and inconsistency using theoretical and statistical approaches. The possibility of publication bias and the strength of evidence will also be examined.Ethics and disseminationThere are no ethical concerns. Results will be published in peer-reviewed journals and presented at practitioners’ conferences.PROSPERO registration numberCRD42020148728.

Abstract Background Interpersonal psychotherapy (IPT) is an intervention that has established efficacy in the prevention and treatment of depressive disorders. Previous systematic reviews have not evaluated the effectiveness of IPT on symptoms of stress, anxiety, depression, quality of life, relationship satisfaction/quality, social supports, and an improved psychological sense of well-being. There is limited data regarding factors that moderate and mediate the effectiveness of IPT including the timing of the intervention or the mode of delivery of IPT intervention. The objective of this systematic review and meta-analysis is to evaluate the effectiveness, feasibility, and acceptability of IPT interventions to treat perinatal psychological distress and to summarize the evidence on predictors, mediators, and moderators of IPT. Methods We will include peer-reviewed studies that recruited perinatal women. The search strategy will involve the following databases: MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), Cochrane Central Register of Controlled Trials (Ovid), CINAHL with Full Text (EBSCO), Social Work Abstracts (EBSCO), SocINDEX with Full Text (EBSCO), Academic Search Complete (EBSCO), Family & Society Studies Worldwide (EBSCO), Family Studies Abstracts (EBSCO), and Scopus. Study inclusion criteria include (1) randomized controlled trials, quasi-experimental studies, and pre-post studies that evaluated the effectiveness of IPT; (2) qualitative studies that evaluated feasibility and acceptability of IPT; (3) study sample included and analyzed perinatal women; and (4) publication language was English. Using pilot-tested screening and data extraction forms, two reviewers will independently review studies in three steps: (1) abstract/title screening, (2) full-text screening of potentially accepted studies, and (3) data extraction of accepted studies. Disagreements will be resolved by a third reviewer. Studies will be aggregated for meta-synthesis and meta-analysis should the data allow for this. Two independent reviewers will grade methodological quality. Discussion Findings from this review will inform future development and implementation of IPT intervention research for perinatal women. Identifying key factors of successful IPT interventions will inform intervention design and adaptation of IPT interventions to increase the likelihood that perinatal women will engage in and benefit from IPT interventions. This review will also identify key considerations for increasing the effectiveness of IPT interventions during the perinatal period. Systematic review registration PROSPERO CRD42019114292

BackgroundGiven the prevalence of chronic nonspecific neck pain (CNSNP) internationally, attention has increasingly been paid in recent years to evaluating the efficacy of therapeutic exercise (TE) in the management of this condition.PurposeThe purpose of this study was to conduct a current review of randomized controlled trials concerning the effect of TE on pain and disability among people with CNSNP, perform a meta-analysis, and summarize current understanding.Data SourcesData were obtained from MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Physiotherapy Evidence Database (PEDro), and Cochrane Central Register of Controlled Trials (CENTRAL) databases from their inception to August 2012. Reference lists of relevant literature reviews also were tracked.Study SelectionAll published randomized trials without any restriction regarding time of publication or language were considered for inclusion. Study participants had to be symptomatic adults with only CNSNP.Data ExtractionTwo reviewers independently selected the studies, conducted the quality assessment, and extracted the results. Data were pooled in a meta-analysis using a random-effects model.Data SynthesisSeven studies met the inclusion criteria. Therapeutic exercise proved to have medium and significant short-term and intermediate-term effects on pain (g=−0.53, 95% confidence interval [CI]=−0.86 to −0.20, and g=−0.45, 95% CI=−0.82 to −0.07, respectively) and medium but not significant short-term and intermediate-term effects on disability (g=−0.39, 95% CI=−0.86 to 0.07, and g=−0.46, 95% CI=−1.00 to −0.08, respectively).LimitationsOnly one study investigated the effect of TE on pain and disability at follow-up longer than 6 months after intervention.ConclusionsConsistent with other reviews, the results support the use of TE in the management of CNSNP. In particular, a significant overall effect size was found supporting TE for its effect on pain in both the short and intermediate terms.

Background Taping is a widely used therapeutic tool for the treatment of musculoskeletal disorders, nevertheless its effectiveness is still uncertain. Purpose The purpose of this study was to conduct a current review of randomized controlled trials (RCTs) concerning the effects of elastic and nonelastic taping on spinal pain and disability. Data Sources MEDLINE, CINAHL, EMBASE, PEDro, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, ISI Web of Knowledge, and SPORTDiscus databases were searched. Study Selection All published RCTs on symptomatic adults with a diagnosis of specific or nonspecific spinal pain, myofascial pain syndrome, or whiplash-associated disorders (WAD) were considered. Data Extraction Two reviewers independently selected the studies and extracted the results. The quality of individual studies was assessed using the PEDro scale, and the evidence was assessed using GRADE criteria. Data Synthesis Eight RCTs were included. Meta-analysis of 4 RCTs on low back pain demonstrated that elastic taping does not significantly reduce pain or disability immediately posttreatment, with a standardized mean difference of −0.31 (95% confidence interval=−0.64, 0.02) and −0.23 (95% confidence interval=−0.49, 0.03), respectively. Results from single trials indicated that both elastic and nonelastic taping are not better than placebo or no treatment on spinal disability. Positive results were found only for elastic taping and only for short-term pain reduction in WAD or specific neck pain. Generally, the effect sizes were very small or not clinically relevant, and all results were supported by low-quality evidence. Limitations The paucity of studies does not permit us to draw any final conclusions. Conclusion Although different types of taping were investigated, the results of this systematic review did not show any firm support for their effectiveness.

Schizophrenia Spectrum

Acceptance and commitment therapy (ACT) has been reported to be effective in the treatment of some psychiatric disorders. It remains uncertain, however, whether ACT is safe and effective in treating schizophrenia spectrum and other psychotic disorders (e.g., psychosis). This protocol describes the methodology for a systematic review and meta-analysis of the safety and efficacy of ACT in the treatment of psychosis. The review will be guided by the standards set by the Cochrane Collaboration. We will search the Allied and Complementary Medicine Database (AMED), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), Excerpta Medica database (EMBASE), EMCARE, Education Resources Information Center (ERIC), MEDLINE, and PsycINFO databases for randomized controlled trials, whose arms are ACT and any comparator, as well as ClinicalTrials.gov, Australian New Zealand Clinical Trials Registry (ANZCTR), and Current Controlled Trials (ISRCTN), for unpublished and ongoing trials. The primary outcome will be any standard (or surrogate) measure of psychotic pathology. The meta-analysis will summarize short-term and long-term effects and different control conditions with or without treatment as usual or comparative to other interventions. In cases where heterogeneity is detected (via χ2 and I2), we will adopt the random effects model for computation.

Objective The aim of this study was to conduct a systematic review and meta-analysis to investigate the impact of premorbid beta-blockers on mortality in patients with sepsis. Data Sources We searched EMBASE, the Cochrane Central Register of Controlled Trials, and MEDLINE for eligible studies. The protocol was registered at the PROSPERO (CRD42021256813). Study Selection Two authors independently evaluated the following inclusion criteria: (1) randomized controlled trials, cohort studies, cross-sectional studies; (2) patients with sepsis aged ≥18 years, and (3) premorbid beta-blocker use. Data Extraction Two authors extracted the patients’ characteristics and outcomes independently. All analyses were performed using the random-effects models. The primary outcome was short-term mortality, defined as mortality within 30 days, in-hospital or intensive care unit mortality. Data Synthesis Ten studies (n = 24 748 patients) were included. The pooled odds ratio (OR) of short-term mortality associated with the premorbid use of beta-blockers was 0.85 (95% confidence interval [CI], 0.69-1.04; P = .12; I2 = 50%). Five studies reported an adjusted OR of short-term mortality. The pooled adjusted OR of short-term mortality associated with the premorbid use of beta-blockers was 0.73 (95% CI, 0.65-0.83; P < .001; I2 = 0%). Conclusion Premorbid beta-blockers were associated with a lower short-term mortality in patients with sepsis.

Simple Obesity

Obesity is a growing chronic health problem worldwide. Studies about acupuncture for obesity treatment are many. But there are some doubts about the effectiveness of acupuncture versus sham acupuncture in treating obesity due to its lack of medical evidence. Therefore, the aim of this study is to assess the efficacy of acupuncture for obesity treatment and provide clinic evidence. Four English databases (PubMed, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials) and four Chinese databases (China National Knowledge Infrastructure, Chinese BioMedical Database, Chinese Scientific Journal Database and Wan-Fang Data) were searched from their receptions to August 2019. Randomized controlled trials (RCTs) using the comparison between acupuncture and sham acupuncture to treat simple obesity were included. The primary outcome of body mass index (BMI) would be used to measure the effect of acupuncture on obesity. According to the trial data extraction form based on the Cochrane Handbook, two reviewers separately extracted the data. Risk of bias of the RCTs was assessed by the Cochrane Risk of Bias Tool. The study included 8 RCTs with 403 patients. When compared with sham acupuncture, acupuncture showed obviously effect in BMI reduction (MD=1.0kg/m2, 95% CI=0.6 to 1.4, P<0.001). There was also significant reduction in body weight (MD=1.85kg, 95%CI=0.82 to 2.88, p<0.001), WC (MD=0.97cm, 95%CI=0.24 to 1.71, p=0.01) and body fat mass percentage (MD=1.01, 95%CI=0.25 to 1.77, p<0.05). However, WHR (MD=0.01, 95%CI=0 to 0.03, p>0.05) was not statistically and significantly different between the acupuncture and control groups. Adverse effects were reported in 3 studies. The review suggests that acupuncture is an effective therapy for simple obesity rather than a placebo effect. This potential benefit needs to be further evaluated by longer-term and more rigorous RCTs.

Abstract Context Denosumab inhibits the receptor activator of nuclear factor κ-Β ligand, an immune system modulator. Safety endpoints including risk for infections were assessed as secondary outcomes in randomized controlled trials (RCTs) of the drug. Objective To assess the risk of serious adverse events of infections (SAEI) in denosumab-treated patients. Data Sources PubMed and Cochrane Central Register of Controlled Trials were searched up to May 27, 2019. Study Selection All RCTs of denosumab (60 mg every 6 months) versus any comparator were included. We excluded trials in cancer patients for prevention of skeletal-related events. Data Extraction Two reviewers independently applied selection criteria and extracted the data. Risk ratios (RR) with 95% confidence intervals (CI) were pooled using a fixed effect model. Sensitivity analysis was based on risk of bias. Data Synthesis Thirty-three studies (22 253 patients) were included. There was a higher incidence of SAEI during denosumab treatment versus any comparator (RR, 1.21; 95% CI, 1.04-1.40; I2 = 0%), mainly of ear, nose, and throat (RR, 2.66; 95% CI, 1.20-5.91) and gastrointestinal origin (RR, 1.43; 95% CI, 1.02-2.01). RR was similar in a sensitivity analysis based on adequate allocation concealment. The RR of any infection (RR, 1.03; 95% CI, 0.99-1.06) and infection-related mortality (RR, 0.50; 95% CI, 0.20-1.23) was comparable between groups. Conclusions A higher incidence of SAEI is demonstrated during treatment with denosumab in an osteoporosis dose. Nevertheless, the overall risk for any infection or related mortality is similar to comparator groups. These findings merit consideration before therapy initiation.

IntroductionAlthough evidence exists for the efficacy of psychosocial interventions in preventing depression, little is known about its prevention through online interventions. The objective of this study is to conduct a systematic review and meta-analysis of randomised controlled trials assessing the effectiveness of online interventions in preventing depression in heterogeneous populations.Methods and analysisWe will conduct a systematic review and meta-analysis of randomised controlled trials that will be identified through searches of PubMed, PsycINFO, WOS, Scopus, OpenGrey, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and Australia New Zealand Clinical Trials Register . We will also search the reference lists provided in relevant studies and reviews. Experts in the field will be contacted to obtain more references. Two independent reviewers will assess the eligibility criteria of all articles, extract data and determine their risk of bias (Cochrane Collaboration Tool). Baseline depression will be required to have been discarded through standardised interviews or validated self-reports with standard cut-off points. The outcomes will be the incidence of new cases of depression and/or the reduction of depressive symptoms as measured by validated instruments. Pooled standardised mean differences will be calculated using random-effect models. Heterogeneity and publication bias will be estimated. Predefined sensitivity and subgroup analyses will be performed. If heterogeneity is relevant, random-effect meta-regression will be performed.Ethics and disseminationThe results will be disseminated through peer-reviewed publication and will be presented at a professional conference. Ethical assessment is not required as we will search and assess existing sources of literature.Trial registration numberCRD42014014804; Results.

Abstract Background Taping is a common treatment modality used by many rehabilitation providers. Several types of tapes and taping methods are used in the treatment of musculoskeletal dysfunction and pain. Purpose To summarize and map the evidence related to taping methods used for various joints and conditions of the musculoskeletal system, and to provide clinicians and researchers with a user-friendly reference with organized evidence tables. Data sources The PEDro, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register for Controlled Trials, PubMed, and PROSPERO databases were searched from inception through October 31, 2019. Study selection Eligible studies were selected by two independent reviewers and included either systematic reviews (SRs) or randomized controlled trials (RCTs) and included a musculoskeletal complaint using a clinical outcome measure. Data extraction Data was extracted by two investigators independently. Risk of bias and quality were assessed using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) for SRs or the Physiotherapy Evidence Database (PEDro) scale for RCTs. The protocol was registered with PROSPERO (CRD42019122857). Data synthesis Twenty-five musculoskeletal conditions were summarized from forty-one SRs and 127 RCTs. There were 6 SRs and 49 RCTs for spinal conditions. Kinesio tape was the most common type of tape considered. Four evidence tables representing the synthesized SRs and RCTs were produced and organized by body region per condition. Limitations Inclusion of only English language studies. Also, the heterogeneous nature of the included studies prevented a meta-analysis. Conclusions There is mixed quality evidence of effectiveness for the different types of taping methods for different body regions and conditions. All of the SRs and RCTs found during our search of the taping literature have been organized into a series of appendices. A synthesis of the results have been placed in evidence tables that may serve as a useful guide to clinicians and researchers.

IntroductionThe prevalence of postpartum depression (PPD) is 17%, and the incidence is 12% worldwide. Adverse consequences for mothers and babies have been associated with this disease. To assess the effectiveness of psychological, psychoeducational and psychosocial interventions in preventing PPD, a systematic review and meta-analysis (SR/MA) will be conducted.Methods and analysisA SR/MA will be performed following the indications of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies will be identified through MEDLINE (Ovid and PubMed), PsycINFO, Web of Science, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, OpenGrey, Australian New Zealand Clinical Trial Registry, ClinicalTrials.gov and evidencebasedtherapy.org from inception until 31 January 2020. Bridging searches will be also conducted until the review is completed. The selection criteria will be as follows: (1) subjects will be pregnant females or females who have given birth in the last 12 months and who were non-depressive at baseline; (2) psychological, psychoeducational and psychosocial interventions; (3) comparator will be usual care, attention control, waiting list or no intervention; (4) outcomes will be specific results on PPD; and (5) the design of the studies will be randomised controlled trials. No restrictions regarding the year of publication, the setting of the intervention or the language of publication will be considered. Pooled standardised mean differences and 95% CIs will be calculated. The risk of bias of the studies will be assessed through the Cochrane Collaboration risk of bias tool. Heterogeneity between the studies will be determined by the I2 and Cochran’s Q statistics. Sensitivity and subgroup analyses will also be performed. Publication bias will be checked with funnel plots and Egger’s test. Heterogeneity will be explored by random-effects meta-regression analysis.Ethics and disseminationThe ethical assessment was not required. The results will be presented at conferences and disseminated through publications.PROSPERO registration numberCRD42018109981.
