School Refusal in Youth: A Systematic Review of Ecological Factors

To guide school practitioners in the identification and intervention of youth with anxious school refusal, this systematic review used an ecological lens to examine the factors that differentiated children and adolescents with school refusal from those without. Based on the rigorous protocol from the Center for Reviews and Dissemination's (CRD) internationally recognized guidelines, 15 studies examining 67 different factors were identified. Results reveal 44 individual, social and contextual factors that differentiate youth with school refusal from peers without school refusal. Findings highlight the centrality of anxiety, or anxiety-related symptoms, and diverse learning needs as main points of contrast between youth with school refusal and those without. Implications of an ecological understanding of the factors associated with school refusal for selective and indicative prevention by school and mental health practitioners are discussed.

Effectiveness of cannabis use and cannabis use disorder interventions: a European and international data synthesis

This data synthesis examined the effectiveness of behavioural and pharmacological approaches for cannabis treatment. We integrated findings from high level evidence studies and prioritised data from Europe when available. The synthesis found that only a relatively small number of published behavioural and pharmacological studies on cannabis interventions have been conducted in Europe. Applying both European and non-European data, it was found that Cognitive Behavioural Therapy (CBT) and/or Motivational Enhancement Therapy (MET) improved short-term outcomes in the frequency of cannabis use and dependency severity, although abstinence outcomes were less consistent. These improvements were typically not maintained nine months after treatment. CBT and MET (or combined CBT + MET) treatments that extend beyond four sessions were more effective than fewer sessions over a shorter duration. Combining CBT or MET (or combined CBT + MET) with adjunctive Contingency Management (CM) improved therapeutic outcomes. No pharmacotherapies have been approved for the management of cannabis use, cannabis use disorders or cannabis withdrawal. Despite only weak evidence to support the use of pharmacological agents, some are used 'off-label' to manage withdrawal symptoms outside clinical trials.

Understanding and addressing femicide in Africa: a systematic review of empirical research

CONTEXT

Against the backdrop of a high prevalence rate of femicide across Africa, it is crucial to gain methodological insights into the existing research on femicide.

OBJECTIVE

To develop evidence-based strategies to address the complex and multifaceted nature of femicide in Africa, ultimately contributing to its prevention and reduction.

DATA SOURCES

Empirical research was searched for using four electronic research databases (ProQuest, Web of Science, EBSCO and PubMed).

ELIGIBILITY CRITERIA

Full-text empirical articles (ie, observational or retrospective studies) published in English between the period of 1 January 1992 and 30 July 2021, which sampled femicide victims and/or perpetrators in Africa, were included in the review.

DATA EXTRACTION

Data were extracted using predefined data fields, including study quality indicators.

DATA SYNTHESIS

Thomas and Harden's (2008) thematic synthesis method was used to analyse 22 empirical articles that met the inclusion criteria in this study.

RESULTS

This review highlights the significant focus on femicide research in South Africa. Most studies of femicides have used cross-sectional research designs. This review also demonstrates that crime dockets have benefited significantly from forensic contributions and police investigations. Furthermore, research efforts have uncovered various contextual factors that contribute to femicide, such as the high prevalence of early childhood trauma and the loss of primary caregivers among femicide offenders.

CONCLUSION

This systematic review offers a thorough synthesis of the current understanding of femicide in an African context, focusing on South Africa. Despite acknowledging the strengths and limitations of the existing knowledge, this review emphasises the urgency of addressing femicide and calls for international attention and action to effectively combat this pressing issue.

US medical school curriculum on opioid use disorder-a topic review of current curricular research and evaluation of winning student-designed opioid curricula for the 2021 Coalition on Physician Education in Substance Use Disorders curricular competition

The opioid crisis in the US severely affected and continues to affect population's health. The opioid crisis was in part fueled by inadequate pain management, which is in part due to the inadequate education in both pain and opioid use disorder (OUD) for health care professionals. In 2021, the Coalition on Physician Education in Substance Use Disorders (COPE) organized a curricular competition soliciting US medical students-designed OUD-related curricula. Twelve winning curricula were identified. Here, we first conducted a topic review regarding current US medical school OUD curricula. Then we evaluated the COPE winning curricula and compared them to the curricula identified in the topic review. For the topic review, ten relevant databases were searched up to December 31, 2021 using a combination of pre-determined keywords. Total of 25 peer-reviewed articles were selected based on the pre-determined criteria, which included 5 articles describing opioid curricular development at the state level (AZ, CA, MA, PA, and RI), 17 research articles evaluating a curriculum developed in a single institution, 2 literature reviews, and 1 article detailing curricular development and validation processes in a single institution. Although vary in organizations and formats, state-level curricula were comprehensive and could be adopted by other states or institutions with necessary local issue-based modifications. Faculty development and critical resources were major challenges for curricular implementation. The 17 research articles exhibited good scientific quality (Medical Education Research Study Quality Instrument (MERSQI) score = 11.94 ± 2.33 (maximal score = 18)). All research articles reported to some extent, the success of respective curriculum, in improving students' knowledge in and/or attitude towards OUD, based on primarily pre- and post- comparisons. Compared to these published curricula, winning students-designed curricula had more specific focuses, diverse learning activities, and varieties in assessment methods. For all curricula, long-term evaluations were lacking. Except for the state level curricula, majority of the other curricula did not emphasize specifically on chronic pain education or the biopsychosocial approach. Interprofessional education approach was also lacking. Our topic review and curricular evaluation highlighted the needs for integrating OUD and chronic pain medical curricula, developing long-term assessment tools, and more OUD curriculum research overall.

Systematic review and meta-analysis on SuperPATH approach versus conventional approaches for hip arthroplasty

AIM

The SuperPATH approach has been in practice for almost a decade. There is no systematic review to date comparing the novel SuperPATH approach with conventional approaches. Therefore, it is important to conduct an up-to-date review to evaluate the benefits and drawbacks of the SuperPATH approach in comparison to widely accepted traditional approaches.Our primary aim was to compare the newer SuperPATH approach with the traditional approaches to the hip in terms of functional outcome and radiological parameters. We also aimed to identify any potential complications of the SuperPATH approach as it is a new surgical technique lacking any published sytematic reviews.

MATERIALS AND METHODS

The review was conducted in accordance with the steps detailed in the Cochrane Handbook for Systematic reviews of intervention and will be reported bearing in mind the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PICO terms were independently searched in multiple databases. Studies that compared SuperPATH with traditional approaches were included in the analysis.

RESULTS

7 studies including a total of 730 patients were available for final analysis. 3 studies were randomised control trials, 2 were prospective cohort studies and 2 were non-randomised case control studies.Patients in the SuperPATH group were discharged earlier (2 days difference in weighted mean). The operative time was 5 minutes longer (84.46 vs. 78.99) and there was a marginal decrease in blood loss (38 ml lesser) in the SuperPATH approach. VAS Score and HHS at the end of 1 year was comparable in both study groups. Cup abduction angle and anteversion angles were acceptable and comparable in both groups.

CONCLUSIONS

The SuperPATH approach shows minimal improvement in length of hospital stay and blood loss with no significant improvement in pain or functional outcome score. There are no major complications reported and the radiological parameters are comparable.

Common data elements reported on middle meningeal artery embolization in chronic subdural hematoma: an interactive systematic review of recent trials

Cross study heterogeneity has limited the evidence based evaluation of middle meningeal artery embolization (MMAE) as a treatment for chronic subdural hematoma (CSDH). Ongoing trials and prospective studies suggest that heterogeneity in upcoming publications may detract from subsequent meta-analyses and systemic reviews. This study aims to describe this data heterogeneity to promote harmonization with common data elements (CDEs) in publications. ClinicalTrials.gov and PubMed were searched for published or ongoing prospective trials of MMAE. The Nested Knowledge AutoLit living review platform was utilized to classify endpoints from randomized control trials (RCTs) and prospective cohort studies comparing MMAE with other treatments. The qualitative synthesis feature was used to determine cross study overlap of outcome related data elements. Eighteen studies were included: 12 RCTs, two non-randomized controlled studies, two prospective single arm trials, one combined prospective and retrospective controlled study, and one prospective cohort study. The most commonly reported data element was recurrence (15/18), but seven heterogenous (non-comparable) definitions were used for 'recurrence'. Mortality was reported in 10/18 studies, but no common timepoint was reported in more than four studies. Re-intervention and CSDH volume were reported in eight studies, CSDH width in seven, and no other outcome was common across more than five studies. There was significant heterogeneity in data element collection even among prospective registered trials of MMAE. Even among CDEs, variation in definition and timepoints prevented harmonization. A standardized approach based on CDEs may be necessary to facilitate future meta-analyses and evidence driven evaluation of MMAE treatment of CSDH.

Systematic Review of Telehospice Telemedicine and e-Health

Background: A 2012 systematic review by Oliver et al. of evidence-based research on telehospice included 26 research articles published between 2000 and 2010 on the use of telehospice connecting hospice professionals with caregivers and their care recipients. The present study replicated research by Oliver et al., extending the time frame from 2010 through 2020. The aim of this study was to answer the question-what is the current state of the evidence related to telehospice services? Materials and Methods: A systematic review was conducted for the time period 2010 to 2020 of the existing literature researching the topic of telehospice. Thirteen articles (five quantitative, six qualitative, and two mixed methods) were found that meet the inclusion criteria of the study. The Methodological Rigor Scoring Instrument was used to code the qualitative and quantitative articles separately to address methodological differences. Results: The most common findings were related to technology adaptation readiness for staff and caregivers. Studies assessed the use of telehospice that included incorporated technology, such as an electronic tablet, to provide synchronous communication between the provider and the patient/caregiver. Provider and caregiver attitudes regarding telehospice care were largely positive with studies reporting acceptance of telehospice as generally high. Conclusions: The past 10 years have yielded a small but significant body of research on telehospice. Published research on the topic reports a generally high level of patient and caregiver satisfaction about the experience, but limited findings have been published relating to patient outcomes. As adaptation of telehospice and technology has surged in the past year, it is expected that additional research on the impact of technology on clinical outcomes will emerge in the future.

Linking political exposures to child and maternal health outcomes: a realist review

BACKGROUND

Conceptual and theoretical links between politics and public health are longstanding. Internationally comparative systematic review evidence has shown links between four key political exposures - the welfare state, political tradition, democracy and globalisation - on population health outcomes. However, the pathways through which these influences may operate have not been systematically appraised. Therefore, focusing on child and maternal health outcomes, we present a realist re-analysis of the dataset from a recent systematic review.

METHODS

The database from a recent systematic review on the political determinants of health was used as the data source for this realist review. Included studies from the systematic review were re-evaluated and those relating to child and/or maternal health outcomes were included in the realist synthesis. Initial programme theories were generated through realist engagement with the prior systematic review. These programme theories were adjudicated and refined through detailed engagement with the evidence base using a realist re-synthesis involving two independent reviewers. The revised theories that best corresponded to the evidence base formed the final programme theories.

RESULTS

Out of the 176 included studies from the systematic review, a total of 67 included child and/or maternal health outcomes and were included in the realist re-analysis. Sixty-three of these studies were ecological and data were collected between 1950 and 2014. Six initial programme theories were generated. Following theory adjudication, three theories in revised form were supported and formed the final programme theories. These related to a more generous welfare state leading to better child and maternal health especially in developed countries through progressive social welfare policies, left-of-centre political tradition leading to lower child mortality and low birth weight especially in developed countries through greater focus on welfare measures, and increased globalisation leading to greater child and infant mortality and youth smoking rates in LMECs through greater influence of multinational corporations and neoliberal trade organisations.

CONCLUSION

We present a realist re-analysis of a large systematically identified body of evidence on how four key political exposures - the welfare state, democracy, political tradition and globalisation - relate to child and maternal health outcomes. Three final programme theories were supported.

Childhood Obesity Evidence Base Project: Building Translational Capacity through Meta-Analytic Methods

Purpose: The purpose of this article is to demonstrate the need for and utility of using a taxonomic approach for evidence aggregation and meta-analyses, with focus on prevention and reduction of childhood obesity in very young children. As evidence has been generated through heterogeneous efforts, it is important that the field makes use of all available evidence to learn what works, for who, and in what circumstances. Methods: The Childhood Obesity Evidence Base (COEB) project conducted a taxonomic meta-analysis, using Grounded Theory to code elements present in reports of existing studies and initiatives, of diverse design and evaluation approaches, which were then mapped onto the levels of the socio-ecologic model. This article is the fourth in a series that describes the COEB project overall. It discusses both generally and specifically how taxonomies contribute to traditional meta-analytic methods, what questions can and cannot be answered, the method's contribution to translational (implementation) capacity, and ability to inform future efforts. Results: The COEB project illustrates how the taxonomic meta-analytic approach broadens the evidence base, increases translational capacity for effective intervention components, and evaluates the influence of contextual elements to inform future initiatives. How the method is used to establish associations between varying intervention components, contextual elements, and outcomes is discussed. Conclusions: Taxonomies generated through this process can be used for meta-analysis, serving to generate topic-specific questions associated with intervention approaches and outcomes in context, which is adjunctive to traditional meta-analytic methods and can inform public health approaches.

The effects of soy isoflavones on total testosterone and follicle-stimulating hormone levels in women with polycystic ovary syndrome: a systematic review and meta-analysis

OBJECTIVES

The aims of this systematic review and meta-analysis were to evaluate the effectiveness of soy isoflavones on serum levels of total testosterone (TT) and follicle-stimulating hormone (FSH) in women with polycystic ovary syndrome (PCOS).

METHODS

A meta-analysis was performed by searching for relevant randomised controlled trials (RCTs) in several databases. Of the four trials found, the eligibility criteria to evaluate the efficacy of soy isoflavones on serum levels of FSH were met by three trials and of TT by four trials. The Cochrane scale was used to evaluate the risk of bias. Fixed-effects and random-effects models were used to evaluate overall effect. The χ ² test (Cochran's Q test) and the I ² index were used to assess the heterogeneity of RCTs.

RESULTS

Our results showed that soy isoflavones significantly decreased TT (weighted mean difference [WMD] - 0.14; 95% confidence interval [CI] - 0.2, -0.02; p = 0.016; I ² = 89%, p < 0.001) but had no significant effect on FSH levels (WMD -0.25; 95% CI -0.54, 0.02; p = 0.06; I ² = 0%, p = 0.85).

CONCLUSION

Although the results of this meta-analysis showed that soy isoflavones in women with PCOS decreased TT and had no significant effect on FSH, better and more valid studies are needed to confirm these results.

The Relevance ofIn Silico,In Vitroand Non-human Primate Based Approaches to Clinical Research on Major Depressive Disorder

Major depressive disorder (MDD) is the most severe form of depression and the leading cause of disability worldwide. When considering research approaches aimed at understanding MDD, it is important that their effectiveness is evaluated. Here, we assessed the effectiveness of original studies on MDD by rating their contributions to subsequent medical papers on the subject, and we compared the respective contribution of findings from non-human primate (NHP) studies and from human-based in vitro or in silico research approaches. For each publication, we conducted a quantitative citation analysis and a systematic qualitative analysis of the citations. In the majority of cases, human-based research approaches (both in silico and in vitro) received more citations in subsequent human research papers than did NHP studies. In addition, the human-based approaches were considered to be more relevant to the hypotheses and/or to the methods featured in the citing papers. The results of this study suggest that studies based on in silico and in vitro approaches are taken into account by medical researchers more often than are NHP-based approaches. In addition, these human-based approaches are usually cheaper and less ethically contentious than NHP studies. Therefore, we suggest that the traditional animal-based approach for testing medical hypotheses should be revised, and more opportunities created for further developing human-relevant innovative techniques.

Current state of home-based exercise interventions in patients with congenital heart disease: a systematic review

Home-based exercise training is a promising alternative to conventional supervised training for patients with congenital heart disease (CHD). Even though the beneficial effect of exercise interventions is well established in patients with CHD, knowledge concerning variety and utility of existing programmes is still lacking. Therefore, the aim of this review is to give an overview about existing home-based exercise interventions in patients with CHD. A systematic search was performed in PubMed, Cochrane, Scopus and PEDro (2008–2018) for relevant clinical trials that provided any kind of home-based exercise with patients with CHD. All articles were identified and assessed by two independent reviewers. Seven articles with 346 paediatric CHD (18 months to 16 years) and five articles with 200 adults with CHD (21–41 years) were included. Most studies performed a supervised home-based exercise intervention with children and adolescents exercising at least three times per week with duration of 45 min for 12 weeks. Reported outcome measurements were health-related quality of life and physical activity, but mostly exercise capacity measured as peak oxygen uptake that improved in four studies (1.2%, 7%, 7.7%, 15%; p<0.05), walking distance in two (3.5%, 19.5%, p<0.05,) or walking time (2 min, p=0.003) in one. The dropout rates were high (15%), and compliance to the training programme was not reported in the majority of the studies (58%). Home-based exercise interventions are safe, feasible and a useful alternative to supervised cardiac rehabilitation for all age groups of patients with CHD. Nevertheless, training compliance represents a major challenge.

Systematic Review and Meta-analysis: Sometimes Bigger Is Indeed Better

Clinicians encounter an ever increasing and frequently overwhelming amount of information, even in a narrow scope or area of interest. Given this enormous amount of scientific information published every year, systematic reviews and meta-analyses have become indispensable methods for the evaluation of medical treatments and the delivery of evidence-based best practice. The present basic statistical tutorial thus focuses on the fundamentals of a systematic review and meta-analysis, against the backdrop of practicing evidence-based medicine. Even if properly performed, a single study is no more than tentative evidence, which needs to be confirmed by additional, independent research. A systematic review summarizes the existing, published research on a particular topic, in a well-described, methodical, rigorous, and reproducible (hence "systematic") manner. A systematic review typically includes a greater range of patients than any single study, thus strengthening the external validity or generalizability of its findings and the utility to the clinician seeking to practice evidence-based medicine. A systematic review often forms the basis for a concomitant meta-analysis, in which the results from the identified series of separate studies are aggregated and statistical pooling is performed. This allows for a single best estimate of the effect or association. A conjoint systematic review and meta-analysis can provide an estimate of therapeutic efficacy, prognosis, or diagnostic test accuracy. By aggregating and pooling the data derived from a systemic review, a well-done meta-analysis essentially increases the precision and the certainty of the statistical inference. The resulting single best estimate of effect or association facilitates clinical decision making and practicing evidence-based medicine. A well-designed systematic review and meta-analysis can provide valuable information for researchers, policymakers, and clinicians. However, there are many critical caveats in performing and interpreting them, and thus, like the individual research studies on which they are based, there are many ways in which meta-analyses can yield misleading information. Creators, reviewers, and consumers alike of systematic reviews and meta-analyses would thus be well-served to observe and mitigate their associated caveats and potential pitfalls.

Self-monitoring to increase physical activity in patients with cardiovascular disease: a systematic review and meta-analysis

BACKGROUND AND AIMS

It is important to encourage physical activity in patients with cardiovascular disease (CVD), and self-monitoring is considered to contribute to increased physical activity. However, the effects of self-monitoring on CVD patients remain to be established. In this study, we examined the influence of self-monitoring on physical activity of patients with CVD via a systematic review and meta-analysis.

METHODS

Screening of randomized controlled trials only was undertaken twice on PubMed (date of appraisal: August 29, 2017). The inclusion criteria included outpatients with CVD, interventions for them, daily step counts as physical activity included in the outcome, and self-monitoring included in the intervention. Assessments of the risk of bias and meta-analysis in relation to the mean change of daily step counts were conducted to verify the effects of self-monitoring.

RESULTS

From 205 studies retrieved on PubMed, six studies were included, with the oldest study published in 2005. Participants included 693 patients of whom 541 patients completed each study program. Their mean age was 60.8 years, and the ratio of men was 79.6%. From these 6 studies, a meta-analysis was conducted with 269 patients of 4 studies including only RCTs with step counts in the intervention group and the control group, and self-monitoring significantly increased physical activity (95% confidence interval, 1916-3090 steps per day, p < 0.05). The average intervention period was about 5 months. Moreover, four studies involved intervention via the internet, and five studies confirmed the use of self-monitoring combined with other behavior change techniques.

CONCLUSION

The results suggest that self-monitoring of physical activity by patients with CVD has a significantly positive effect on their improvement. Moreover, the trend toward self-monitoring combined with setting counseling and activity goals, and increased intervention via the internet, may lead to the future development and spread of self-monitoring for CVD patients.

Facilitators and Barriers for Advance Care Planning Among Ethnic and Racial Minorities in the U.S.: A Systematic Review of the Current Literature

Growing evidence suggests a low engagement in advance care planning (ACP) among ethnic minorities in the U.S. The purpose of this study was to synthesize findings from prior research about ACP among ethnic minorities. An extensive literature search was conducted using multiple electronic databases. After applying inclusion criteria, 26 studies were included. Four categories of facilitators and barriers to ACP were identified: (1) Socio-demographic factors, (2) health status, literacy and experiences, (3) cultural values, and (4) spirituality. Socio-demographic factors showed inconsistent findings regarding their association with ACP engagement. Worse health status and knowledge about ACP are common facilitators across ethnic minority groups, whereas mistrust toward the health care system was a barrier only for Blacks. Collectivistic cultural values influenced ACP engagement among Latinos and Asian Americans; however, spirituality/religion played an important role among Blacks. The implications for culturally competent approaches to promote ACP and future research directions are discussed.

How much evidence is there that political factors are related to population health outcomes? An internationally comparative systematic review

OBJECTIVES

To provide a 7-year update of the most recent systematic review about the relationships between political features and population health outcomes.

SETTING

Internationally comparative scholarly literature.

DATA SOURCES

Ten scholarly bibliographic databases plus supplementary searches in bibliographies and Google Scholar were used to update a previous systematic review. The final search was conducted in November 2017.

PRIMARY AND SECONDARY OUTCOME MEASURES

Any population health outcome measure, apart from healthcare spending.

RESULTS

73 unique publications were identified from the previous systematic review. The database searches to update the literature identified 45 356 raw records with 35 207 remaining following de-duplication. 55 publications were identified from supplementary searches. In total, 258 publications proceeded to full-text review and 176 were included in narrative synthesis. 85 studies were assessed at low risk of bias, 89 at moderate risk of bias and none at high risk of bias. Assessment could not be conducted for two studies that had only book chapters. No meta-analysis was conducted. 102 studies assessed welfare state generosity and 79 found a positive association. Of the 17 studies that assessed political tradition, 15 were found to show a positive association with the left-of-centre tradition. 44 studies assessed democracy and 34 found a positive association. 28 studies assessed globalisation and 14 found a negative association, while seven were positive and seven inconclusive.

CONCLUSIONS

This review concludes that welfare state generosity, left-of-centre democratic political tradition and democracy are generally positively associated with population health. Globalisation may be negatively associated with population health, but the results are less conclusive. It is important for the academic public health community to engage with the political evidence base in its research as well as in stakeholder engagement, in order to facilitate positive outcomes for population health.

Neuroscience of Virtual Reality: From Virtual Exposure to Embodied Medicine

Is virtual reality (VR) already a reality in behavioral health? To answer this question, a meta-review was conducted to assess the meta-analyses and systematic and narrative reviews published in this field in the last twenty-two months. Twenty-five different articles demonstrated the clinical potential of this technology in both the diagnosis and the treatment of mental health disorders: VR compares favorably to existing treatments in anxiety disorders, eating and weight disorders, and pain management, with long-term effects that generalize to the real world. But why is VR so effective? Here, the following answer is suggested: VR shares with the brain the same basic mechanism: embodied simulations. According to neuroscience, to regulate and control the body in the world effectively, the brain creates an embodied simulation of the body in the world used to represent and predict actions, concepts, and emotions. VR works in a similar way: the VR experience tries to predict the sensory consequences of an individual's movements, providing to him/her the same scene he/she will see in the real world. To achieve this, the VR system, like the brain, maintains a model (simulation) of the body and the space around it. If the presence in the body is the outcome of different embodied simulations, concepts are embodied simulations, and VR is an embodied technology, this suggests a new clinical approach discussed in this article: the possibility of altering the experience of the body and facilitating cognitive modeling/change by designing targeted virtual environments able to simulate both the external and the internal world/body.

The 2016 HIGh Heels: Health effects And psychosexual BenefITS (HIGH HABITS) study: systematic review of reviews and additional primary studies

Background

High-heeled shoes (high heels) are frequently worn by many women and form an important part of female gender identity. Issues of explicit and implicit compulsion to wear high heels have been noted. Previous studies and reviews have provided evidence that high heels are detrimental to health. However, the evidence base remains fragmented and no review has covered both the epidemiological and biomechanical literature. In addition, no review has considered the psychosexual benefits that offer essential context in understanding the public health challenge of high heels.

Methods

We searched seven major bibliographic databases up to November 2016, in addition to supplementary searches. We initially identified all review articles of any design that assessed either the psychosexual benefits or negative musculoskeletal health effects of high heels, the latter looking at both the epidemiological and biomechanical perspectives. We additionally considered additional primary studies on areas that had not been reviewed before or in which a marked lack of evidence had been noted. Data were extracted onto standardised forms. Proportionate second review was conducted.

Results

A total of 506 unique records were identified, 27 full-text publications were screened and 20 publications (7 reviews and 13 additional studies) were included in our evidence synthesis. The most up-to-date epidemiological review provides clear evidence of an association between high heel wear and hallux valgus, musculoskeletal pain and first-party injury. The body of biomechanical reviews provides clear evidence of changes indicative of increased risk of these outcomes, as well as osteoarthritis, which is not yet evidenced by epidemiological studies. There were no reviews on psychosexual benefits, but all five identified original studies provided evidence of increased attractiveness and/or an impact on men’s behaviour associated with high heel wear. With regard to second-party injury, evidence is limited to one descriptive study and eight case reports.

Conclusions

Our evidence synthesis clearly shows that high heels bring psychosexual benefits to women but are detrimental to their health. In light of this dilemma, it is important that women’s freedom of choice is respected and that any remaining issues of explicit or implicit compulsion are addressed.

The effectiveness of postoperative intervention in patients after rhinoplasty: a meta-analysis

Rhinoplasty is the most common facial plastic surgical procedure, and the occurrence of periorbital edema and ecchymosis is normal after rhinoplasty. The goal of this study was to perform a systematic review with meta-analysis of the efficacy of postoperative care of edema and ecchymosis following rhinoplasty. Two authors independently searched the databases (PubMed, SCOPUS, Embase, Web of Science, and the Cochrane database) from inception to September 2016. We included studies that compared postoperative care methods (intervention groups) with no treatment (control group) where the outcomes of interest were edema, ecchymosis, and satisfaction rate of patients on postoperative days. Sufficient data for meta-analysis were retrieved for 11 trials with a total of 627 patients. Eyelid edema and ecchymosis during the first 7 days postoperatively were statistically decreased in the arnica administration groups versus the control group. Eyelid edema and ecchymosis during the first 24 h postoperatively were statistically decreased in the cold compression group versus the control group. The ratio of patient satisfaction was statistically higher in the tapping application group than in the control group. However, the analysis indicated that surgeons had a significant tendency to decrease intranasal packing. The administration of arnica, cold compression, and tape could reduce eyelid edema and ecchymosis. Intranasal packing was associated with more adverse effects in terms of postoperative ecchymosis compared to non-packing. However, additional trials with thorough research methodologies should be conducted to confirm the results of this study.

Patient and miniscrew implant factors influence the success of orthodontic miniscrew implants

Data sourcesMedline via PubMed, Scopus and Web of Science databases were searched from January 2003 to March 2015 limited to human studies published in English. Manual searches for the relevant reference lists and a grey literature search via Google Scholar were also conducted.Study selectionProspective and retrospective studies about the stability of miniscrew implants (MIs) used for orthodontic anchorage into the posterior buccal region were considered. Two review authors independently assessed titles and abstracts, and evaluated full manuscripts for the meta-analysis.Data extraction and synthesisThe outcome measure was the success rate of MIs which had to be explicitly reported in order to enable its computation as odds ratios with regards to patient factors (age (years), < 20 vs. ≥ 20; sex, male vs. female; jaw of insertion, maxilla vs. mandible) and MI factors (length, < 8 mm vs. ≥ 1.4 mm; diameter, ≤ 1.4 mm vs. > 1.4 mm). The quality of the studies was assessed using the Newcastle-Ottawa Scale (NOS). The meta-analysis was expressed as combined OR and heterogeneity was evaluated (Cochran Q and I²). Subgroup meta-analysis was conducted based on study design, study quality and MIs sample size. Publication bias analysis (Begg's and Eggar's tests) and sensitivity analysis were performed.ResultsSeventeen non-randomised studies, five prospective and 12 retrospective, were included. Significantly higher success rates were observed for the maxillary MIs (14 studies odds ratio (OR), 2.32; 95% CI, 1.81-4.08), older patients (six studies OR, 1.59; 95% CI, 1.14-2.22), and for longer MIs (four studies OR, 0.56 (1/0.46= 2.17); 95% CI, 0.26-0.20) and MIs with larger diameter (four studies OR, 0.62 (1/0.62= 1.61); 95% CI, 0.40-0.97), whereas there was no difference observed between male and female patients (13 studies OR, 1.18; 95% CI, 0.92-1.51). All subgroups acquired homogeneity except for the components of study design regarding the jaw of insertion.ConclusionsThe results of this meta-analysis based on non-randomised clinical studies showed that jaw of insertion, age, MI length and MI diameter are critical risk factors to the success of MIs, whereas sex was not influential.Source of FundingThe Basic Science Research Program of the National Research Foundation of Korea was stated as the source of funding.

Effects of whole body vibration on bone mineral density in postmenopausal women: a systematic review and meta-analysis

This systematic review and meta-analysis of randomized controlled trials (RCTs) identified significant effects of whole body vibration (WBV) on bone mineral density (BMD) of the lumbar spine (in the sensitivity analysis and seven subgroup analyses), femoral neck (in one subgroup analysis), and trochanter (four subgroup analyses) in postmenopausal women, but not other measurements of BMD.

INTRODUCTION

Interventions using WBV training have been conducted in postmenopausal women, aimed at increasing BMD; however, the results are contradictory. Our objective is to conduct a systematic review and meta-analysis of RCTs examining WBV effect on BMD.

METHODS

RCTs were considered eligible, with follow-up ≥6 months, which verified the effects of WBV on the BMD of postmenopausal women. The calculations of the meta-analysis were performed through the weighted mean difference between the WBV and control groups, or the WBV and combined training, through the absolute change between pre- and post-intervention in the areal bone mineral density (aBMD) or trabecular volumetric bone mineral density (vBMDt).

RESULTS

Fifteen RCTs were included in the meta-analysis. No differences were observed in the primary analysis. WBV was found to improve aBMD compared with the control group, after exclusion of studies with low quality methodological (lumbar spine), when excluding the studies which combined WBV with medication or combined training (lumbar spine), with the use of low frequency and high magnitude (lumbar spine and trochanter), high frequency and low magnitude (lumbar spine), high cumulative dose and low magnitude (lumbar spine), low cumulative dose and high magnitude (lumbar spine and trochanter), with semi-flexed knee (lumbar spine, femoral neck, and trochanter), and side-alternating type of vibration (lumbar spine and trochanter).

CONCLUSIONS

Despite WBV presenting potential to act as a coadjuvant in the prevention or treatment of osteoporosis, especially for aBMD of the lumbar spine, the ideal intervention is not yet clear. Our subgroup analyses helped to demonstrate the various factors which appear to influence the effects of WBV on BMD, contributing to clinical practice and the definition of protocols for future interventions.

Prenatal Maternal Anxiety as a Risk Factor for Preterm Birth and the Effects of Heterogeneity on This Relationship: A Systematic Review and Meta-Analysis

Background. Systematic reviews (SR) and meta-analyses (MA) that previously explored the relationship between prenatal maternal anxiety (PMA) and preterm birth (PTB) have not been comprehensive in study inclusion, failing to account for effects of heterogeneity and disagree in their conclusions. Objectives. This SRMA provides a summary of the published evidence of the relationship between PMA and PTB while examining methodological and statistical sources of heterogeneity. Methods. Published studies from MEDLINE, CINAHL, PsycINFO, and EMBASE, until June 2015, were extracted and reviewed. Results. Of the 37 eligible studies, 31 were used in this MA; six more were subsequently excluded due to statistical issues, substantially reducing the heterogeneity. The odds ratio for PMA was 1.70 (95% CI 1.33, 2.18) for PTB and 1.67 (95% CI 1.35, 2.07) for spontaneous PTB comparing higher levels of anxiety to lower levels. Conclusions. Consistent findings indicate a significant association between PMA and PTB. Due to the statistical problem of including collinear variables in a single regression model, it is hard to distinguish the effect of the various types of psychosocial distress on PTB. However, a prenatal program aimed at addressing mental health issues could be designed and evaluated using a randomised controlled trial to assess the causal nature of different aspects of mental health on PTB.

Trends in Pediatric Versus Adult Ophthalmology Publications Over 15 Years

PURPOSE

To evaluate and compare trends in different categories of pediatric and adult ophthalmology publications.

METHODS

Publications in ophthalmology between January 1, 1998, and December 31, 2012, were retrieved from PubMed. An age filter separated pediatric from adult articles.

RESULTS

There was a significant linear increase in the number of publications in both pediatric and adult publications. There was an increase over time in pediatric and adult clinical trials, letters to the editor, meta-analyses, and systematic reviews. There was a significant increase in adult randomized controlled trials only. No meaningful statistical analyses could be conducted for practice guidelines.

CONCLUSIONS

Pediatric and adult ophthalmology have demonstrated a significant increase in annual published articles. Practicing ophthalmologists have an increasing number of articles to read and might become more and more dependent on search engines and reviews to remain informed, emphasizing the need for official practice guidelines that are, unfortunately, seldom published.

Centralized monitoring and virtual consultant models of tele-ICU care: a systematic review

BACKGROUND

Increasing intensivist shortages and demand coupled with the escalating cost of care have created enthusiasm for intensive care unit (ICU)-based telemedicine ("tele-ICU"). This systematic literature review compares the Centralized Monitoring and Virtual Consultant tele-ICU Models.

MATERIALS AND METHODS

With an experienced medical reference librarian, we identified all language publications addressing the employment and efficacy of the centralized monitoring and virtual consultant tele-ICU systems through PubMed, CINAHL, and Web of Science. We performed quantitative and qualitative reviews of documents regarding financial sustainability, clinical outcomes, and ICU staff workflow and acceptance.

RESULTS

Of 1,468 documents identified, 1,371 documents were excluded, with the remaining 91 documents addressing clinical outcomes (46 documents [enhanced guideline compliance, 5; mortality and length of stay, 28; and feasibility, 13]), financial sustainability (9 documents), and ICU staff workflow and acceptance (36 documents). Quantitative review showed that studies evaluating the Centralized Monitoring Model were twice as frequent, with a mean of 4,891 patients in an average of six ICUs; Virtual Consultant Model studies enrolled a mean of 372 patients in an average of one ICU. Ninety-two percent of feasibility studies evaluated the Virtual Consultant Model, of which 50% were in the last 3 years. Qualitative review largely confirmed findings in previous studies of centralized monitoring systems. Both the Centralized Monitoring and Virtual Consultant Models showed clinical practice adherence improvement. Although definitive evaluation was not possible given lack of data, the Virtual Consultant Model generally indicated lean absolute cost profile in contrast to centralized monitoring systems.

CONCLUSIONS

Compared with the Virtual Consultant tele-ICU Model, studies addressing the Centralized Monitoring Model of tele-ICU care were greater in quantity and sample size, with qualitative conclusions of clinical outcomes, staff satisfaction and workload, and financial sustainability largely consistent with past systematic reviews. Attention should be focused on performing more high-quality studies to allow for equitable comparisons between both models.

Individual treatment response in attention-deficit/hyperactivity disorder: broadening perspectives and improving assessments

Attention-deficit/hyperactivity disorder (ADHD) is a highly complex disorder with multiple treatment options. Impairments associated with ADHD, rather than symptoms defining the disorder, are the primary reason for referral of individuals to clinical services; consequently, they should also be key targets for intervention. Impairments are moderated by factors such as comorbidities, family environment and intelligence quotient, and particular challenges may vary between patients. The understanding of patient and family treatment preferences, as well as identification of treatment needs and goals, should drive future clinical practice. This review addresses the assessment of ADHD treatment goals and outcomes in clinical practice, and discusses changes in future clinical research studies necessary to progress the utilization of an individualized medicine approach in ADHD.
