Meta-Analysis Review
STUDY DESIGN
A systematic review with meta-analysis.
OBJECTIVE
The aim of this study was to conduct a systematic review and meta-analysis of current evidence evaluating the effectiveness of rehabilitation following lumbar fusion surgery (LFS).
SUMMARY OF BACKGROUND DATA
LFS for the management of lower back pain, with(out) neurogenic leg pain, is increasing as the population ages. Clinical outcomes commonly lag behind surgical outcomes and 40% of patients experience significant back-related disability 12 months after LFS. Identifying rehabilitation strategies to improve function and quality of life following LFS is important.
METHODS
A systematic review of databases were searched, including MEDLINE, CINAHL, and grey literature. Studies identified were screened for inclusion by title and abstract. Full text of eligible/potentially eligible studies was evaluated against predetermined eligibility criteria. Included studies were subjected to critical appraisal and risk of bias evaluation. The GRADE approach to quality of evidence was utilized. A meta-analysis comparing usual care with "complex rehabilitation," comprising exercise and cognitive behavioral therapy, for outcomes relating to pain, disability, fear of movement, and mental health was conducted at short and longer term (<3 and >12 months postsurgery) time points.
RESULTS
Three studies were identified for the systematic review and 2 included in the meta-analysis (n = 237, female = 62%, mean age = 55). Low-quality evidence suggests that "complex rehabilitation" provides short-term improvement in disability [effect size, -0.85, 95% confidence interval (95% CI), -1.41 to -0.29] and fear avoidance behavior (-1.07, 95% CI -1.33, -0.80), compared with usual care. Low-quality evidence exists favoring "complex rehabilitation" over usual care for longer term disability (-0.84, 95% CI -1.11 to -0.58) and fear avoidance behavior (-1.40, 95% CI -1.69 to -1.12).
CONCLUSIONS
A small number of low-quality studies suggest that "complex rehabilitation" reduces short and long-term disability and fear avoidance behavior following LFS. More, high-quality research is required to confirm the effectiveness of "complex rehabilitation" programs.

Meta-Analysis Review
BACKGROUND
Young women, especially adolescents, often lack access to modern contraception. Reasons vary by geography and regional politics and culture. The projected 2015 birth rate in 'developing' regions was 56 per 1000 compared with 17 per 1000 for 'developed' regions.
OBJECTIVES
To identify school-based interventions that improved contraceptive use among adolescents
SEARCH METHODS
Until 6 June 2016, we searched for eligible trials in PubMed, CENTRAL, ERIC, Web of Science, POPLINE, ClinicalTrials.gov and ICTRP.
SELECTION CRITERIA
We considered randomized controlled trials (RCTs) that assigned individuals or clusters. The majority of participants must have been 19 years old or younger.The educational strategy must have occurred primarily in a middle school or high school. The intervention had to emphasize one or more effective methods of contraception. Our primary outcomes were pregnancy and contraceptive use.
DATA COLLECTION AND ANALYSIS
We assessed titles and abstracts identified during the searches. One author extracted and entered the data into RevMan; a second author verified accuracy. We examined studies for methodological quality.For unadjusted dichotomous outcomes, we calculated the Mantel-Haenszel odds ratio (OR) with 95% confidence interval (CI). For cluster randomized trials, we used adjusted measures, e.g. OR, risk ratio, or difference in proportions. For continuous outcomes, we used the adjusted mean difference (MD) or other measures from the models. We did not conduct meta-analysis due to varied interventions and outcome measures.
MAIN RESULTS
The 11 trials included 10 cluster RCTs and an individually randomized trial. The cluster RCTs had sample sizes from 816 to 10,954; the median number of clusters was 24. Most trials were conducted in the USA and UK; one was from Mexico and one from South Africa.We focus here on the trials with moderate quality evidence and an intervention effect. Three addressed preventing pregnancy and HIV/STI through interactive sessions. One trial provided a multifaceted two-year program. Immediately after year one and 12 months after year two, the intervention group was more likely than the standard-curriculum group to report using effective contraception during last sex (reported adjusted ORs 1.62 ± standard error (SE) 0.22) and 1.76 ± SE 0.29), condom use during last sex (reported adjusted ORs 1.91 ± SE 0.27 and 1.68 ± SE 0.25), and less frequent sex without a condom in the past three months (reported ratios of adjusted means 0.50 ± SE 0.31 and 0.63 ± SE 0.23). Another trial compared multifaceted two-year programs on sexual risk reduction and risk avoidance (abstinence-focused) versus usual health education. At 3 months, the risk reduction group was less likely than the usual-education group to report no condom use at last intercourse (reported adjusted OR 0.67, 95% CI 0.47 to 0.96) and sex without a condom in the last three months (reported adjusted OR 0.59, 95% CI 0.36 to 0.95). At 3 and after 15 months, the risk avoidance group was also less likely than the usual-education group to report no condom use at last intercourse (reported adjusted ORs 0.70, 95% CI 0.52 to 0.93; and 0.61, 95% CI 0.45 to 0.85). At the same time points, the risk reduction group had a higher score than the usual-education group for condom knowledge. The third trial provided a peer-led program with eight interactive sessions. At 17 months, the intervention group was less likely than the teacher-led group to report oral contraceptive use during last sex (OR 0.57, 95% CI 0.36 to 0.91). This difference may not have been significant if the investigators had adjusted for the clustering. At 5 and 17 months, the peer-led group had a greater mean increase in knowledge of HIV and pregnancy prevention compared with the control group. An additional trial showed an effect on knowledge only. The group with an emergency contraception (EC) session was more likely than the group without the EC unit to know the time limits for using hormonal EC (pill) and the non-hormonal IUD as EC.
AUTHORS' CONCLUSIONS
Since most trials addressed preventing STI/HIV and pregnancy, they emphasized condom use. However, several studies covered a range of contraceptive methods. The overall quality of evidence was low. Main reasons for downgrading the evidence were having limited information on intervention fidelity, analyzing a subsample rather than all those randomized, and having high losses.

American Journal of Clinical Dermatology Nov 2021Patients with vitiligo experience reduced quality of life.
BACKGROUND
Patients with vitiligo experience reduced quality of life.
OBJECTIVE
To comprehensively describe the available evidence for psychosocial burden in vitiligo.
METHODS
A systematic review of observational studies and clinical trials identified using PubMed, EMBASE, Scopus, and the Cochrane databases was performed through 1 March, 2021, to assess psychosocial comorbidities in vitiligo. Two independent reviewers performed an assessment of articles and extracted data for qualitative synthesis.
RESULTS
Included studies (N = 168) were published between 1979 and 1 March, 2021; 72.6% were published since 2010. Disorders including or related to depression (41 studies, 0.1-62.3%) and anxiety (20 studies, 1.9-67.9%) were the most commonly reported. The most prevalent psychosocial comorbidities were feelings of stigmatization (eight studies, 17.3-100%), adjustment disorders (12 studies, 4-93.9%), sleep disturbance (seven studies, 4.6-89.0%), relationship difficulties including sexual dysfunction (ten studies, 2.0-81.8%), and avoidance or restriction behavior (12.5-76%). The prevalence of most psychosocial comorbidities was significantly higher vs healthy individuals. Factors associated with a significantly higher burden included female sex, visible or genital lesions, age < 30 years (particularly adolescents), and greater body surface area involvement, among others. The most commonly reported patient coping strategy was lesion concealment.
LIMITATIONS
Available studies were heterogeneous and often had limited details; additionally, publication bias is possible.
CONCLUSIONS
The results of this systematic review show that vitiligo greatly affects psychosocial well-being. The extent of psychosocial comorbidities supports the use of multidisciplinary treatment strategies and education to address the vitiligo-associated burden of disease.

Increasing pressure on limited healthcare resources has necessitated the development of measures promoting early discharge and avoiding inappropriate hospital (re)admission. This systematic review examines the evidence for interventions in acute hospitals including (i) hospital-patient discharge to home, community services or other settings, (ii) hospital discharge to another care setting, and (iii) reduction or prevention of inappropriate hospital (re)admissions. Academic electronic databases were searched from 2005 to 2018. In total, ninety-four eligible papers were included. Interventions were categorized into: (1) pre-discharge exclusively delivered in the acute care hospital, (2) pre- and post-discharge delivered by acute care hospital, (3) post-discharge delivered at home and (4) delivered only in a post-acute facility. Mixed results were found regarding the effectiveness of many types of interventions. Interventions exclusively delivered in the acute hospital pre-discharge and those involving education were most common but their effectiveness was limited in avoiding (re)admission. Successful pre- and post-discharge interventions focused on multidisciplinary approaches. Post-discharge interventions exclusively delivered at home reduced hospital stay and contributed to patient satisfaction. Existing systematic reviews on tele-health and long-term care interventions suggest insufficient evidence for admission avoidance. The most effective interventions to avoid inappropriate re-admission to hospital and promote early discharge included integrated systems between hospital and the community care, multidisciplinary service provision, individualization of services, discharge planning initiated in hospital and specialist follow-up.

Review
Implicit cognitions may be involved in the development and maintenance of specific Internet use disorders such as problematic social network use (PSNU). In more detail, implicit attitude, attentional biases, approach and avoidance tendencies as well as semantic memory associations are considered relevant in the context of PSNU. This viewpoint article summarizes the available literature on implicit cognitions in PSNU. We systematically reviewed articles of implicit cognitions in PSNU from PubMed, Scopus, Web of Science, and ProQuest databases based on a targeted search strategy and assessed using predefined inclusion and exclusion criteria. The present findings suggest that specific implicit cognitions are important in the context of PSNU and therefore show parallels to other addictive behaviors. However, the empirical evidence is limited to a few studies on this topic. Implicit cognitions in PSNU should be explored in more depth and in the context of other affective and cognitive mechanisms in future work.

Meta-Analysis Review
UNLABELLED
Activity pacing is ubiquitous in chronic pain management and aims to reduce pain-contingent avoidance of activity to improve functioning. A meta-analysis, however, has linked pacing with higher levels of pain and disability. One potential explanation is an overlap between existing measures of pacing and avoidance, leading to links with poorer outcomes that are typically associated with avoidance. This study systematically reviews the evidence regarding the relationship between measures of pacing and avoidance. A search was conducted for studies measuring both constructs in adults with chronic pain. A meta-analysis of correlations between pacing and avoidance was conducted; 16 studies were included and a small positive correlation was found (r = .290, P < .001) overall. Single-item and multiple-item measures were also compared; a moderate positive correlation was found for multiple-item measures (r = .410, P < .001), which differed significantly from a small positive correlation found for single-item measures (r = .105, P < .001). Due to limited studies, independent analyses of individual subscales were not possible. Existing measures of pacing-particularly multiple-item measures-may partially confound pacing with avoidance. Further research is required to ensure that a reliable measure of pacing that distinguishes this construct from avoidance is available to adequately evaluate pacing instruction and the effect of pacing on key outcomes in chronic pain.
PERSPECTIVE
This meta-analysis examines the correlation between pacing and avoidance in adults with chronic pain. Results indicate that existing measures may partially confound pacing with avoidance. Directions for future research are proposed to ensure that an adequate measure of pacing exists to evaluate its effect on key outcomes in chronic pain.

Review
Although endoscopic techniques have many advantages including improved visualization and magnification, they are also associated with limitations. The objective of this review is to discuss the practical aspects that can reduce complications after endoscopic procedures, and their management. The review is based on the personal experience of more than 2000 neuroendoscopic procedures performed by the senior author. Topic search was made on PubMed using Neuroendoscopy, complications and neuroendoscopy, complication avoidance and neuroendoscopy, endoscopic neurosurgery, and minimally invasive neurosurgery. Relevant articles were selected after analyzing abstracts and/or topics. Endoscopic procedures are also associated with limitations such as obstruction in instruments manipulation, steep learning curve, blind area, difficulty in visualization, disorientation, loss of stereoscopic image and others. Neuroendoscopy is distinct from microsurgery and the surgeon has to learn endoscopic skills in addition to microsurgical techniques. Difficulties in controlling bleeding, working in a limited area, higher complication rate during the initial learning curve and longer operative time are some of the limitations. Attending live workshops, practicing on models, and hands on cadaveric workshops can reduce the learning curve. Proper case selection, multidisciplinary team approach, watching operative video, visiting other departments, observing a skillful endoscopic surgeon, lab training, and simulators can improve results and shorten the learning curve. Limitations of this review are that the search is limited to the English literature and personal experience of a single surgeon that may create some bias. Although neuroendoscopic techniques are associated with improved results in some indications, they have many limitations. Neuroendoscopic skills need to be learned to improve results.

Meta-Analysis
Decision Avoidance (DA) strategies allow people to forego or abandon effortful deliberation by postponing, bypassing, or delegating a decision. DA is thought to reduce regret, primarily by allowing decision makers to evade personal responsibility for potential negative outcomes. We tested this relation between DA and post-decision regret in a multilevel meta-analysis of 59 effect estimates coming from 13 papers. Five DA strategies were considered: status quo preservation, action omission, inaction inertia, choice delegation and choice deferral. Across all effects and DA strategies, there was a non-significant trend toward DA reducing regret (Hedges' g = -0.23, p = 0.063). When assessing individual strategies, we found that only status quo preservation reduced regret reliably (Hedges' g = -0.45, p = 0.006). The relationship between DA and regret was unclear for the other DA strategies. We tested a number of moderators for the effect. Only 'previous experience' (i.e., the outcome of a previous decision) influenced the relation between DA and regret reliably. That is, if participants choose the DA option when the same choice previously led to a negative outcome, regret is actually enhanced. Overall, there is clear evidence that status quo preservation can reduce regret, but it is currently unclear whether the same holds for other DA strategies.

Meta-Analysis
OBJECTIVES
Non-suicidal self-injury (NSSI) is the intentional and deliberate damage to an individual's own body tissue without the intent to suicide. Individuals who have higher self-reported levels of experiential avoidance are more likely to report a history of NSSI. The current study systematically reviewed the literature and meta-analysed studies assessing associations between experiential avoidance and self-injury.
METHOD
An extensive review was conducted of several databases (including ProQuest, Joanna Briggs, Web of Science, PsychArticles, PubMed, Scopus, and Ovid). Nineteen articles (two dissertations) met the inclusion criteria for the systematic review and 14 were analysed in a Robust Bayesian Meta-analysis. This review was registered through PROSPERO (CRD42020198041).
RESULTS
There was a small to medium, pooled effect size (d = 0.48, 95 % Credibility Interval 0.00-0.85). There was strong evidence for this effect size (Bayes Factor = 12.16), although there was considerable heterogeneity between studies (τ =0.68, 95 % CI [0.44, 0.1.05]). The analysis testing whether these findings may be due to publication bias was inconclusive (Bayes Factor = 2.45).
LIMITATIONS
The majority of studies included were cross-sectional, in English, and most studies were of university students. While some studies reported on recency/frequency of NSSI there was not enough data to conduct meta-analysis.
CONCLUSION
These results suggest there is a robust association between history of NSSI and experiential avoidance. However, as most studies operationalise avoidance as a unidimensional construct, it is not clear which aspects of avoidance differentiate individuals with and without a history of NSSI.

Meta-Analysis Review
The endocannabinoid system is a promising candidate for anxiolytic therapy, but translation to the clinic has been lagging. We meta-analyzed the evidence for anxiety-reduction by compounds that facilitate endocannabinoid signaling in humans and animals. To identify areas of specific potential, effects of moderators were assessed. Literature was searched in Pubmed and Embase up to May 2021. A placebo/vehicle-control group was required and in human studies, randomization. We excluded studies that co-administered other substances. Risk of bias was assessed with SYRCLE's RoB tool and Cochrane RoB 2.0. We conducted three-level random effects meta-analyses and explored sources of heterogeneity using Bayesian regularized meta-regression (BRMA). The systematic review yielded 134 studies. We analyzed 120 studies (114 animal, 6 human) that investigated cannabidiol (CBD, 61), URB597 (39), PF-3845 (6) and AM404 (14). Pooled effects on conditioned and unconditioned anxiety in animals (with the exception of URB597 on unconditioned anxiety) and on experimentally induced anxiety in humans favored the investigational drugs over placebo/vehicle. Publication year was negatively associated with effects of CBD on unconditioned anxiety. Compared to approach avoidance tests, tests of repetitive-compulsive behavior were associated with larger effects of CBD and URB597, and the social interaction test with smaller effects of URB597. Larger effects of CBD on unconditioned anxiety were observed when anxiety pre-existed. Studies reported few side effects at therapeutic doses. The evidence quality was low with indications of publication bias. More clinical trials are needed to translate the overall positive results to clinical applications.
