RESULTS

Studies on non-pharmacological interventions in the management of labor pain have continued to develop since 2003 with great momentum. In this study, the most productive country in research on non-pharmacological interventions was found to be Iran, while Australia, the USA, China, and the United Kingdom were the most notable ones in terms of collaboration. The most prevalently studied non-pharmacological interventions were hydrotherapy and acupuncture. The results of the co-word analysis revealed 5 main themes about this field of research.

CONCLUSION

The results of this study showed that interest in studies on non-pharmacological interventions in the management of labor pain has increased, the quality of research in the field is high, international collaboration is increasingly higher, and technological approaches have started to emerge in relevant studies.

The Top Ranked 101 Articles in Pediatric Surgical Journals from an Altmetric Perspective

INTRODUCTION

 In the era of scientific digitalization, online media platforms gain increasing popularity to accomplish research output awareness. The Altmetric Attention Score AAS weights these online mentions based on a privy algorithm. We aimed to characterize the top 100 articles with the highest (AAS) published in pediatric surgery journals.

MATERIALS AND METHODS

 Publications from six core pediatric surgery journals were retrieved from www.altmetric.com in January 2023 and ranked by their AAS. The top 101 publications were analyzed for their bibliometric measures, study design, and quality as well as online media mentions.

RESULTS

 The top 101 AAS articles were published between 1974 and 2022, preferentially from the United States (64%) and mainly in Journal of Pediatric Surgery (73%), followed by Journal of Pediatric Surgery Case Reports, Pediatric Surgery International, Seminars in Pediatric Surgery, and European Journal of Pediatric Surgery. Their AAS ranged between 21 and 389 (median: 33), with Twitter/X being mostly responsible for online mentions (n = 2,189; 75%). The number of citations in peer-reviewed journals ranged between 0 and 358 (median: 16) and did not correlate to AAS. Retrospective study design (33%) with low evidence level IV (43%) dominated.

CONCLUSION

 The Journal of Pediatric Surgery is the main source of high-profile AAS publications in pediatric surgery. The altmetric popularity of articles is predominantly achieved by their propagation via X, irrespective of the study quality and recognition in the scientific community. Thus, active "twitterism" may play the key role to reach high AAS scores.

Ethical challenges for Health Technology Assessment (HTA) in the evolving evidence landscape

Since its inception, Health Technology Assessment (HTA) has typically determined the value of a technology by collecting information derived from randomized clinical trials (RCTs), in line with the principles of evidence-based medicine (EBM). However, data from RCTs did not constitute the sole source of information, as other types of evidence (such as primary qualitative research) have often been utilized. Recent advances in both generating and collecting other types of evidence are broadening the landscape of evidence, adding complexity to the discussion of "robustness of evidence." What are the consequences of these recent developments for the methodology and conduct of HTA, the HTA community, and its ethical commitments? The aim of this article is to explore some ethical challenges that are emerging in the current evolving evidence landscape, particularly changes in evidence generation and collection (e.g., diversification of data sources), and shifting standards of evidence in the field of HTA (e.g., increasing acceptability of evidence that is thought of as lower quality). Our conclusion is that deciding how to best maintain trustworthiness is common to all these issues.

Discontinuation and non-publication of randomized controlled trials on cervical cancer or precancer

BACKGROUND

Research waste is a considerable problem in clinical trials, with nonpublication being a significant contributor. We aimed to determine the prevalence of discontinuation and nonpublication of randomized controlled trials (RCTs) on cervical cancer or precancer.

METHODS

We searched ClinicalTrials.gov for registered RCTs investigating cervical cancer or precancer that started between January 2000 and December 2020. The primary and secondary outcomes were trial nonpublication and premature discontinuation, respectively. Publication status was determined by systematic searches of peer-reviewed journals using the PubMed and Scopus databases.

RESULTS

A total of 113 RCTs met the inclusion criteria. Among the 85 trials completed before December 2020, 44 (51.8%) were prematurely discontinued and 40 (47.1%) were unpublished. A single-center design (61.4% vs. 34.1%, P = .012) and lack of external funding (59.1% vs. 36.6%, P = .038) were significantly associated with trial discontinuation. Large-scale (target sample size >400; 46.7% vs. 17.5%, P = .004) and externally funded trials (66.7% vs. 35.0%, P = .004) were more likely to be published. Multivariate logistic analysis revealed that a large sample size [odd ratio (OR): 4.125, 95% confidence interval (CI): 1.511-11.259, P = .006] and presence of external funding (OR: 3.714, 95% CI: 1.513-9.117, P = .004) were independent positive factors for trial publication.

CONCLUSION

A significant proportion of RCTs related to cervical cancer or precancer were discontinued early or remain unpublished, resulting in a waste of research resources.

Update on Platelet-Rich Plasma and Platelet-Rich Fibrin for Dermatologic Surgery: Addressing Knowns and Unknowns

BACKGROUND

Autologous and allogeneic platelet-rich plasma (PRP) in addition to its derivatives, such as platelet-rich fibrin (PRF), are broadly accepted therapeutic approaches in orthopedics, otolaryngology, sports medicine, plastic surgery, and oral and maxillofacial surgery. However, the absence of expert consensus, standardized protocols, and varying outcomes pose challenges to their broader acceptance in cosmetic dermatology and dermatologic surgery.

OBJECTIVE

To offer a contemporary literature overview of PRP and PRF, focusing on fundamental aspects of the technology, diversity of commercially accessible systems, and shed light on present-day controversies within the field.

METHODS

A systemic review of PRP and PRF literature was conducted, utilizing search engine databases: Cochrane Database of Systematic Reviews, Embase, Ovid MEDLINE, and PubMed. Emphasis was placed on scrutinizing higher level-of-evidence articles, specifically randomized control trials, systematic reviews, and meta-analyses (Level 1A-2A), with particular emphasis on recent data that have not been well reviewed in other publications from January 2022 to May 2024.

RESULTS

An increasing body of literature affirms advantages of PRP products in dermatology, spanning wound care, facial rejuvenation, scar revision, and hair growth.

CONCLUSION

A foundational understanding of variation in preparation protocol, outcomes, and timing of administration is needed to better comprehend market dynamics, patient demand, and strategies for integrating PRP into dermatologic practice.

Disseminated Superficial Actinic Porokeratosis: A Systematic Treatment Review

BACKGROUND

Disseminated superficial actinic porokeratosis (DSAP) is a disorder of keratinization characterised by small, brown plaques with elevated keratotic rims, typically occurring on sun exposed areas. DSAP poses a risk for malignant transformation, emphasising the need for effective management strategies.

OBJECTIVE

The aim of this study was to review the current reported management options for DSAP.

METHODS

This systematic review was based on a comprehensive search of databases (Cochrane, PubMed, Medline, Embase, Emcare, ProQuest, Web of Science, CINAHL) from inception to 15 March 2024. Studies reporting management of DSAP were included irrespective of study design.

RESULTS

Of 923 citations, 61 studies were included, predominantly comprising case reports and retrospective case series. A limited number of randomized and open-label trials were identified. Various treatment modalities were reported, including topical and systemic agents, photodynamic therapy, and laser therapy.

CONCLUSION

Multiple management options are available for DSAP, including topical and systemic agents, photodynamic therapy and laser treatments. However, these approaches vary in their balance between efficacy and toxicity. Currently, there is a paucity of high-quality clinical trial data to guide treatment decisions. Further studies are required to determine the most effective and safe management strategies for DSAP. PROSPERO REGISTRATION: CRD42024514558.

Clinical and Cost-Effectiveness of Intraoperative Flap Perfusion Assessment With Indocyanine Green Fluorescence Angiography in Breast and Head and Neck Reconstructions: A Systematic Review and Meta-Analysis

BACKGROUND

Indocyanine green fluorescence angiography (ICGFA) is gaining popularity for the assessment of reconstructive flap perfusion intraoperatively. This study analyses the literature with a focus on its clinical efficacy and cost-effectiveness across various plastic and reconstructive surgery procedures.

METHODS

A systematic review was conducted in accordance with PRISMA guidelines on published studies in English comparing ICGFA with standard clinical assessment for flap perfusion. Meta-analysis concerned perfusion-related complications and cost data.

RESULTS

Twenty-five studies met the inclusion criteria, of which two were randomized controlled trials (RCTs) and four were prospective cohort studies. Twenty-one studies were AHRQ Standard 'Good'; however, the overall level of evidence remains low. ICGFA was predominantly performed in breast surgeries (n = 3310) and head and neck reconstruction (n = 701) albeit with inconsistency in protocols and predominantly subjective interpretations (only five studies utilized objective thresholds). In breast surgery, meta-analysis demonstrated significant reductions in mastectomy skin flap necrosis (odds ratio (OR) 0.58, p < 0.0001), fat necrosis (OR 0.31, p < 0.001), infection (OR 0.66, p = 0.02), and re-operation (OR 0.40, p < 0.0001), but no significant decrease in total or partial flap loss (OR 0.78, p = 0.57/OR 0.87, p = 0.56, respectively) or increase in dehiscence (OR 1.55, p = 0.11). In head and neck surgery, ICGFA significantly decreased total flap loss (OR 0.47, p = 0.04), although not partial flap loss (OR 0.37, p = 0.13) and reoperation (OR 0.92, p = 0.73). Lower limb (n = 104) and abdominal wall (n = 95) reconstructive surgeries were much less studied with no significant ICGFA impact. Seven studies reported cost savings with flap surgeries and breast reconstructions, although study heterogeneity precluded meta-analysis.

CONCLUSIONS

ICGFA appears to be a useful, cost-effective tool to identify otherwise unsuspected hypoperfusion in breast and head and neck reconstruction. There is a clear need for standardization, however, to avoid bias. Further RCTs are necessary to solidify these promising clinical findings.

Exploring the fragility of meta-analyses in ophthalmology: a systematic review

OBJECTIVE

The fragility index (FI) of a meta-analysis evaluates the extent that the statistical significance can be changed by modifying the event status of individuals from included trials. Understanding the FI improves the interpretation of the results of meta-analyses and can help to inform changes to clinical practice. This review determined the fragility of ophthalmology-related meta-analyses.

METHODS

Meta-analyses of randomized controlled trials with binary outcomes published in a journal classified as 'Ophthalmology' according to the Journal Citation Report or an Ophthalmology-related Cochrane Review were included. An iterative process determined the FI of each meta-analysis. Multivariable linear regression modeling evaluated the relationship between the FI and potential predictive factors in statistically significant and non-significant meta-analyses.

RESULTS

175 meta-analyses were included. The median FI was 6 (Q1-Q3: 3-12). This meant that moving 6 outcomes from one group to another would reverse the study's findings. The FI was 1 for 18 (10.2%) of the included meta-analyses and was ≤5 for 75 (42.4%) of the included meta-analyses. The number of events (p < 0.001) and the p-value (p < 0.001) were the best predictors of the FI in both significant and non-significant meta-analyses.

CONCLUSION

The statistical significance of meta-analyses in ophthalmology often hinges on the outcome of a few patients. The number of events and the p-value are the most important factors in determining the fragility of the evidence. The FI is an easily interpretable measure that can supplement the reader's understanding of the strength of the evidence being presented.

Management of treatment-naïve diabetic macular edema patients: Review of real-world clinical data

The high prevalence of Diabetic macular edema (DME) is a real global health problem. Its complex pathophysiology involves different pathways. Over the last decade, the introduction of intravitreal treatments has dramatically changed the management and prognosis of DME. Among the different treatment options, inhibitors of vascular endothelial growth factor (anti-VEGF) and intravitreal steroids implants represent the first-line therapy of DME. We conducted a review of electronic databases to compile the available evidence about the clinical management of DME in a clinical setting, with a special focus on treatment-naïve patients. Anti-VEGF therapies represent a valuable option for treating DME patients. However, many patients do not respond properly to this treatment and, due to its administration regimen, many patients receive suboptimal treatment in real life. Current evidence demonstrated that in patients with DME, DEX-i improved significantly both anatomic and visual outcomes. Besides eyes with insufficient anti-VEGF respond or recalcitrant DME cases, DEX-i can be effectively and safely used in treatment-naïve DME patients as first line therapy. DEX-i may be considered first line therapy in different clinical scenarios, such as DME eyes with a greater inflammatory component, patients with cardiovascular events, vitrectomized eyes, or those requiring cataract surgery. In conclusion, there are still many points for improvement pending in the clinical management of the patient with DME. Since DME treatment must follow a patient-tailored approach, selecting the best therapeutic approach for each patient requires a good understanding of the pathophysiology of DME.

Human Capital and Productivity in Surgery Research Across the Globe: A Big Data Analysis Using Artificial Intelligence

INTRODUCTION

No investigation of each nation's contribution to knowledge production and human capital in surgery currently exists. Previous studies explored country-level research productivity only in few surgical subspecialties. To identify current and future leaders in surgery research, we conduct a retrospective observational study of each country's human capital and research productivity.

METHODS

A web-scraping algorithm was deployed on PubMed to retrieve information on the first and senior author of every publication in all PubMed-indexed surgery outlets-a total of 388 journals-between 2010 and 2022, according to the SCImago classification. Each country's human capital is proxied by the number of first and senior authors.

RESULTS

A total of 665,668 publications from 110 countries were reviewed. The number of publications rises over time. The United States represents 30.78% and 31.32% of global publications based on first and senior authors, respectively. Other leading contributors include the United Kingdom (5.57% and 5.69% of global first and senior author publications, respectively), China (8.84% and 8.74%), Japan (7.14% and 7.10%), and Italy (4.54% and 4.46%). The number of publications per 100K people ranges between 0.04 and 86.01, suggesting widely varying levels of research productivity relative to the population.

CONCLUSIONS

Our findings underscore the US dominance in surgery research. Countries with a higher share of first or senior authors may have greater capacity to expand their future research output. As big data research expands, we expect studies deploying artificial intelligence methodologies, such as web scraping, on data repositories to guide healthcare provision and health policy decisions to become mainstream.

Identifying evidence-practice gaps for shoulder injury risk factors in competitive swimmers: uniting literature and expert opinion

OBJECTIVES

To identify evidence-practice gaps regarding shoulder injury risk factors in competitive swimmers.

METHODS

We gathered insights from 27 swimming experts including elite swimmers, coaches, high-performance staff and applied researchers using Concept Mapping. Participants brainstormed, sorted and rated (from 1 (least) to 10 (most) important and modifiable) their ideas of shoulder injury risk factors in competitive swimmers. Proposed risk factors rated above the grand mean for importance (6.2±0.4) or modifiability (6.5±0.5) ratings were considered highly important/modifiable. Expert opinions were then juxtaposed with systematic review findings to identify overlaps or convergences.

RESULTS

Brainstorming generated 126 proposed shoulder injury risk factors for competitive swimmers, subsequently refined to 61 unique proposed risk factors by removing duplicates and combining similar responses. The participants sorted the 61 risk factors into seven distinct clusters. Experts perceived 36/61 proposed risk factors as highly important, of which 6 were supported by literature, 6 showed no association with injury, 2 had conflicting evidence and the remaining 22 have not yet been investigated, suggesting an evidence-practice gap. Three proposed risk factors 'inconsistent training load', 'poor stroke technique' and 'low posterior shoulder strength-endurance' exhibited high perceived importance, high perceived modifiability and supporting evidence.

CONCLUSION

An evidence-practice gap was identified for 28 proposed risk factors perceived as highly important by swimming experts despite either (1) no relevant empirical research (n=22), or (2) no association with injury (n=6) from synthesised evidence. Greater collaboration between researchers and practitioners is needed to effectively address shoulder injury risk factors in competitive swimmers.

Implant design influences the joint-specific outcome after total knee arthroplasty

Aims

The aims were to assess whether joint-specific outcome after total knee arthroplasty (TKA) was influenced by implant design over a 12-year follow-up period, and whether patient-related factors were associated with loss to follow-up and mortality risk.

Methods

Long-term follow-up of a randomized controlled trial was undertaken. A total of 212 patients were allocated a Triathlon or a Kinemax TKA. Patients were assessed preoperatively, and one, three, eight, and 12 years postoperatively using the Oxford Knee Score (OKS). Reasons for patient lost to follow-up, mortality, and revision were recorded.

Results

A total of 94 patients completed 12-year functional follow-up (62 females, mean age 66 years (43 to 82) at index surgery). There was a clinically significantly greater improvement in the OKS at one year (mean difference (MD) 3.0 (95% CI 0.4 to 5.7); p = 0.027) and three years (MD 4.7 (95% CI 1.9 to 7.5); p = 0.001) for the Triathlon group, but no differences were observed at eight (p = 0.331) or 12 years' (p = 0.181) follow-up. When assessing the OKS in the patients surviving to 12 years, the Triathlon group had a clinically significantly greater improvement in the OKS (marginal mean 3.8 (95% CI 0.2 to 7.4); p = 0.040). Loss to functional follow-up (53%, n = 109/204) was independently associated with older age (p = 0.001). Patient mortality was the major reason (56.4%, n = 62/110) for loss to follow-up. Older age (p < 0.001) and worse preoperative OKS (p = 0.043) were independently associated with increased mortality risk. An age at time of surgery of ≥ 72 years was 75% sensitive and 74% specific for predicting mortality with an area under the curve of 78.1% (95% CI 70.9 to 85.3; p < 0.001).

Conclusion

The Triathlon TKA was associated with clinically meaningful greater improvement in knee-specific outcome when compared to the Kinemax TKA. Loss to follow-up at 12 years was a limitation, and studies planning longer-term functional assessment could limit their cohort to patients aged under 72 years.

Caseload per Year in Robotic-Assisted Minimally Invasive Esophagectomy: A Narrative Review

Esophageal surgery is deemed one of the most complex visceral operations. There is a well-documented correlation between higher caseload and better outcomes, with hospitals that perform more surgeries experiencing significantly lower mortality rates. The approach to caseload per year varies across different countries within Europe. Germany increased the minimum annual required caseload of complex esophageal surgeries from 10 to 26 starting in 2023. Furthermore, the new regulations present challenges for surgical training and staff recruitment, risking the further fragmentation of training programs. Enhanced regional cooperation is proposed as a solution to ensure comprehensive training. This review explores the benefits of robotic-assisted minimally invasive esophagectomy (RAMIE) in improving surgical precision and patient outcomes and aims to evaluate how the caseload per year influences the quality of patient care and the efficacy of surgical training, especially with the integration of advanced robotic techniques.

Evidence-based orthobiologic practice: Current evidence review and future directions

The field of orthopedic and regenerative medicine is rapidly evolving with the increasing utilization of orthobiologic. These biologically derived therapies, including platelet-rich plasma, mesenchymal stem cells, bone marrow aspirate concentrate, stromal vascular fraction (SVF), and autologous chondrocyte implantation, are gaining traction for their potential to enhance the body's natural healing processes. They offer a promising alternative to traditional surgical interventions for musculoskeletal injuries and degenerative conditions. Current evidence suggests significant benefits of orthobiologics in treating conditions like osteoarthritis, tendon injuries, and spinal disorders, yet inconsistencies in treatment protocols and outcomes persist. The global market for orthobiologics is projected to grow substantially, driven by advancements in biologic therapies such as adipose-derived stem cells and SVF, and the demand for minimally invasive treatments. Despite their promise, regulatory and ethical challenges, as well as the need for high-quality, standardized research, remain significant obstacles. Future directions in the field include advancements in delivery systems, personalized medicine approaches, and the exploration of novel sources like induced pluripotent stem cells, aiming for more targeted and effective treatments. Collaborative efforts are crucial to overcoming these challenges and ensuring the safe and effective application of orthobiologics in clinical practice.

Is tobacco consumption a risk factor for central serous chorioretinopathy? A systematic review and meta-analysis

Central serous chorioretinopathy (CSC) is a prevalent exudative maculopathy. Understanding risk factors for CSC is important for disease prevention and to provide evidence-based advice to patients. In this study, we systematically reviewed the literature and performed meta-analysis on the association between tobacco consumption and CSC. We searched 12 literature databases on May 5, 2024, and identified 11 eligible studies of 27 595 patients with CSC and 105 354 control individuals. Studies were predominantly clinic-based case-control studies. We calculated a summary estimate of tobacco consumption as a risk factor for CSC at an odds ratio of 2.99 (95% CI: 1.82-4.93, p = 0.000017), which remained statistically significant in the sensitivity analyses. The exact mechanism by which tobacco consumption contribute to the pathophysiology of CSC remains unclear, although several potential hypotheses exist. However, tobacco consumption is a modifiable behaviour and tobacco cessation is an actionable advice with which patients with CSC themselves can play a large role in disease management. Further studies are warranted to understand the impact of tobacco cessation for risk modification and for the prognosis of patients who already have CSC.

Ultrasound-guided fascial plane blocks in chronic pain: a narrative review

BACKGROUND

Recent studies have unveiled the intricate and distinctive nature of fascia, no longer regarding it solely as a muscle container. Recent research highlights its complex innervation and structure, signifying its significance in chronic pain pathways.

METHODS

We conducted a systematic literature search (updated on February 2024) to evaluate the role of fascial plane blocks in chronic pain treatment. All article types (randomized clinical trials, prospective and retrospective observational studies along with case reports and case series) were deemed eligible for inclusion if they referenced "fascial plane blocks" for the control of chronic pain conditions (persistent post-surgical, neuropathic, musculoskeletal-myofascial and cancer-related) and were published between 2010 and February 2024.

RESULTS

The search revealed an increasing evidence in the literature for the implementation of fascial blocks in chronic pain management, although still heavily limited to case reports or series.

CONCLUSION

With the integration of ultrasound technology and a deeper understanding of their mechanisms of action, the fascial plane blocks continue to broaden their application also in chronic pain management, as a part of a multimodal strategy or as an alternative to conventional drugs or opioids.

[Translated article] AEDVAEDV Expert Recommendations on the Management of Suppurative Sexually Transmitted Infections

The incidence of sexually transmitted infections (STIs) is increasing in Spain. Suppurative STIs are one of the most frequent reasons for consultation in specialized centers. The reason for suppurative STIs is multiple and their empirical treatment varies with the currently growing problem of antimicrobial resistance. Dermatologists are trained and prepared to treat these diseases, but their correct management requires active knowledge of national and international guidelines. The present document updates, reviews and summarizes the main expert recommendations on the management and treatment of these STIs.

Crafting the Future of Community-Based Medical Rehabilitation: Exploring Optimal Models for Non-Inpatient Rehabilitation Services through a Narrative Review

Community-based medical rehabilitation encompasses diverse programs that cater to patients outside of inpatient settings, such as home rehabilitation, day rehabilitation centers, and ambulatory clinics. While inpatient rehabilitation principles are widely standardized, outpatient programs display significant variability influenced by healthcare models, local environments, economic constraints, and available resources. This narrative review aims to explore and synthesize the various models of non-inpatient rehabilitation services, evaluating their effectiveness, cost-efficiency, and patient satisfaction. The review also seeks to identify optimal practices and strategies to enhance community-based rehabilitation, alleviate the burden on inpatient facilities, and improve patient outcomes through multidisciplinary and patient-centered approaches. Additionally, the study examines the critical role of a professional program coordinator and the importance of effective clinical communication in outpatient rehabilitation. A comprehensive search of peer-reviewed literature was conducted across multiple databases, focusing on studies that examined community-based rehabilitation models. The findings suggest that community-based rehabilitation programs are generally more cost-effective than inpatient programs, with their success being heavily dependent on the intensity and timing of interventions. Multidisciplinary approaches and high-intensity rehabilitation have shown promise in improving patient quality of life, though their effectiveness varies by condition. Despite limited research, the involvement of a Physical and Rehabilitation Medicine (PRM) physician as a program coordinator appears vital for ensuring continuity of care. Moreover, effective clinical communication is essential, impacting all aspects of patient care and interprofessional collaboration, with continuous adaptation required to meet the evolving needs of diverse patient populations.

The top 100 most-cited articles in dentistry by authors with Italian affiliation

INTRODUCTION

Analyzing highly-cited articles can provide a retrospective assessment of research evolution and predict future developments. The aim of this study was to carry out a bibliometric analysis of the 100 most-cited articles in dentistry by authors with an Italian affiliation.

EVIDENCE ACQUISITION

All the articles published in journals indexed under the Scopus category "Dentistry" and with at least one author affiliated to any Italian institution were searched in September 2022. The 100 most-cited articles were selected and relevant data were extracted and summarized. The analysis of co-authorship at country level and co-occurrence of keywords was carried out.

EVIDENCE SYNTHESIS

The 100 most-cited articles were published between 1976 and 2020. The number of citations ranged from 235 to 1683, with a mean of 361. The series included 25 citation classics (>400 citations). The majority of articles were classified as expert opinion/narrative reviews (N.=47). Almost half of the articles refer to three predominant disciplines which were implantology, periodontology and restorative dentistry. Only two articles were single-authored. In 30 articles, all the authors had an Italian affiliation and the US was the most frequent country for non-Italian authors. Only one article was published in journals owned by a non-Italian publisher.

CONCLUSIONS

The present series of highly-cited articles confirms the important role of Italy in dental research. We found an absence of correlation between the level of evidence and the number of citations and a non-homogeneous distribution of highly-cited papers in the different dental disciplines. The majority of articles included in the series shared international co-authorship and were published in high-impact journals.

Interventions to decrease health students' stigma toward schizophrenia: A scoping review

BACKGROUND

Schizophrenia is heavily stigmatized among health professionals. Given that health professional students are future members of the workforce and will provide care for people with schizophrenia, it is essential to implement interventions aimed at reducing stigma among this group.

OBJECTIVE

This scoping review aimed to identify and synthesize existing literature on interventions to decrease schizophrenia stigma among health professional students, and to determine the possible gaps in the literature.

DESIGN

Nine electronic databases and gray literature were searched, including PubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, MEDLINE, Web of Science, Scopus, China National Knowledge Infrastructure, WanFang, and Google on 5 May 2023. Two researchers independently conducted data screening, data extraction, and assessed study risks. A most updated search was also done on 22 May 2024. The Cochrane risk of bias tool version 2 for randomized trials and Risk of Bias in Non-randomized Studies were used to assess the studies' risk of bias. Data synthesis and analysis were conducted by two reviewers using a narrative approach. Reporting adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

RESULTS

This review included twenty-one studies with 2520 health professional students. The majority of included studies were non-randomized controlled trials (38 %) and pre-post studies (52 %). Most of the included studies were conducted in the United States (24 %). The participants in ten (48 %) studies were medical students. The number of intervention sessions ranged from one to 13, with an average of three. Seven (33 %) studies had an intervention duration of less than four weeks and 16 (76 %) studies had no follow-up. Various scales were used to assess the outcomes of schizophrenia stigma. Only two studies (10 %) indicated the intervention's ineffectiveness, with the majority of interventions led by psychiatry department faculty and individuals with schizophrenia.

CONCLUSIONS

Most studies (90 %) utilized various approaches, including face-to-face or online education, direct contact with individuals with schizophrenia, or a combination thereof, to diminish stigma among health professional students. However, none addressed cultural and empathy factors in their intervention designs, and the included studies lacked theoretical guidance. The review only comprised English quantitative studies with significant heterogeneity, with 17 studies (81 %) displaying serious or high risk of bias, limiting comprehensive discussions. These findings offer valuable insights for future systematic review.

TWEETABLE ABSTRACT

Studies on reducing health professional students' schizophrenia stigma need to address cultural and empathy factors.

In-Person Healthcare Simulation: An Umbrella Review of the Literature

SUMMARY STATEMENT

Given the large accumulation of research focused on the effectiveness of in-person simulation-based education (SBE), this umbrella review-or systematic review of systematic reviews-was conducted using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to analyze collective findings and close identified literature gaps. This study presents a descriptive analysis of the most effective modalities, methods, and measurements of in-person SBE, as well as major themes that emerged during analysis as it relates to SBE outcomes.The major patterns or themes that emerged confirm for the first time a longstanding sentiment in the literature, specifically the following: a need to produce higher-quality research with greater rigor, larger sample sizes, more randomized controlled trials, mixed methods, and longitudinal studies. These findings suggest a need to redirect scientific efforts in SBE. Despite the nearly ubiquitous issues noted across the systematic reviews' findings, results of this umbrella review seem to support the notion that in-person simulation-based education improves learning outcomes including technical and nontechnical skills and behavioral and attitudinal change. Analyses highlighted the need to improve overall research approaches and reduce redundancy, as well as the need to standardize terminology, broaden global diversity, and push for further research funding opportunities to support these efforts.

Analysis of Top 100 Articles Cited in Top Pain Journals: A Comprehensive Two Decade Bibliometric Analysis

PURPOSE OF REVIEW

A bibliometric analysis was performed to analyze and compare the top 100 articles from the most well-known five pain journals: Pain, Pain Physician, Pain Medicine, Regional Anesthesia & Pain Medicine, and Journal of Pain. A query of the Scopus database was performed to filter the top 200 most cited articles from each journal. CY score was calculated for the top 200 articles from each journal by dividing the total number of citations by the number of years the article has been published.

RECENT FINDINGS

All articles had a collective analysis of the top CY scores, the top 100 of which were further analyzed. The pain subtype, type of publication, country of origin, and senior author were extrapolated from these top 100 articles. Frequency tables were organized, revealing Pain Journal as the highest publishing journal out of the top 100 articles. Chronic pain was the most studied subtype of pain and narrative reviews were the most common type of evidence. Studies were also organized in five-year epochs to analyze the frequency of publications in these intervals. Results show that 2010-2014 had the highest frequency of articles published overall. Journal Impact Factor (JIF) is also an objective indicator of the average number of citations per published article from each journal.

REPAIRS Delphi: A UK and Ireland Consensus Statement on the Management of Infected Arterial Pseudoaneurysms Secondary to Groin Injecting Drug Use

OBJECTIVE

Consensus guidelines on the optimal management of infected arterial pseudoaneurysms secondary to groin injecting drug use are lacking. This pathology is a problem in the UK and globally, yet operative management options remain contentious. This study was designed to establish consensus to promote better management of these patients, drawing on the expert experience of those in a location with a high prevalence of illicit drug use.

METHODS

A three round modified Delphi was undertaken, systematically surveying consultant vascular surgeons in the UK and Ireland using an online platform. Seventy five vascular surgery units were invited to participate, with one consultant providing the unit consensus practice. Round one responses were thematically analysed to generate statements for round two. These statements were evaluated by participants using a five point Likert scale. Consensus was achieved at a threshold of 70% or more agreement or disagreement. Those statements not reaching consensus were assessed and modified for round three. The results of the Delphi process constituted the consensus statement.

RESULTS

Round one received 64 (86%) responses, round two 59 (79%) responses, and round three 62 (83%) responses; 73 (97%) of 75 units contributed. Round two comprised 150 statements and round three 24 statements. Ninety one statements achieved consensus agreement and 15 consensus disagreement. The Delphi statements covered sequential management of these patients from diagnosis and imaging, antibiotics and microbiology, surgical approach, wound management, follow up, and additional considerations. Pre-operative imaging achieved consensus agreement (97%), with computed tomography angiography being the modality of choice (97%). Ligation and debridement without arterial reconstruction was the preferred approach at initial surgical intervention (89%). Multidisciplinary management, ensuring holistic care and access to substance use services, also gained consensus agreement.

CONCLUSION

This comprehensive consensus statement provides a strong insight into the standard of care for these patients.

Treatment in persistent genital arousal disorder: a scoping review

Background

Persistent genital arousal disorder (PGAD) is a rare condition characterized by unwanted and distressing symptoms of arousal and dysesthesia. The aim of this scoping review was to map the current state of PGAD management, identify gaps in the literature, and understand patient perspectives.

Methods

We completed a scoping review following guidelines from the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta Analyses Scoping Reviews extension. A systematic literature search for articles pertaining to PGAD/genito-pelvic dysesthesia (GPD) was conducted in August 2023 via Medline, Embase, Scopus, and Web of Science. The search returns were deduplicated and the remaining titles and abstracts were screened for inclusion. General publication characteristics and treatment data were extracted from the included publications via a pilot-tested Google form. All screening and extraction were completed in a masked, duplicate fashion.

Results

Findings from our scoping review revealed a scarcity of systematic research, limited evidence-based data, and the importance of addressing both physical and psychiatric concerns. Our sample included 46 publications from an initial pool of 636 returns. Case studies were the most common study design. Thirty-three studies examined medication, either alone or as part of a treatment regimen. Selective serotonin reuptake inhibitors were the most used medication, followed by pramipexole and carbamazepine. Seven studies used a surgical or procedural intervention. Treatment with pelvic floor Botox was the most common procedure. Patient perspectives in the included case studies highlighted themes of shame, suicidal ideation, social isolation, decreased sleep, and overall decline in quality of life.

Conclusion

The findings from our study emphasize patients' distressing and psychiatric symptoms, indicating a need to improve treatment regimens, using both evidence-based research outcomes and patient-reported outcomes. Management for PGAD/GPD lacks a standardized framework, indicating a need for further research and the development of clinical practice guidelines to improve patient care.

Acne and the cutaneous microbiome: A systematic review of mechanisms and implications for treatments

Acne vulgaris is a pervasive skin disease characterized by inflammation of sebaceous units surrounding hair follicles. It results from the complex interplay between skin physiology and the intricate cutaneous microbiome. Current acne treatments, while effective, have major limitations, prompting a shift towards microbiome-based therapeutic approaches. This study aims to determine the relationship between acne and the cutaneous microbiome, assess the effects of current treatments on the cutaneous microbiome and explore the implications for developing new therapies. A systematic review was performed using PubMed and SCOPUS databases within the last 10 years. Methodological quality was assessed independently by two authors. The search retrieved 1830 records, of which 26 articles met the inclusion criteria. Meta-analysis of alpha diversity change was assessed using fixed and randomized effect models per therapeutic group. Eight studies pertain to the role of the cutaneous microbiome in acne, identifying C. acnes, S. aureus and S. epidermidis as key contributors through overproliferation, commensalism or dysbiosis. Eleven studies discuss current acne treatments, including doxycycline (1), topical benzoyl peroxide (BPO) (4), isotretinoin (2), sulfacetamide-sulfur (SSA) (2) and aminolevulinic acid-photodynamic therapy (ALA-PDT) (2), identified as modulating the cutaneous microbiome as a mechanism of efficacy in acne treatment. Seven studies discuss new treatments with topical probiotics, plant derivatives and protein derivatives, which contribute to acne clearance via modulation of dysbiosis, inflammatory markers and diversity indexes. A meta-analysis of the effects of existing therapeutics on the cutaneous microbiome identified benzoyl peroxide as the only treatment to facilitate significant change in diversity. Despite the heterogeneity of study types and microbiome classifications limiting the analysis, this review underscores the complexity of microbial involvement in acne pathogenesis. It delineates the effects of acne therapeutics on microbial diversity, abundance and composition, emphasizing the necessity for personalized approaches in acne management based on microbiome modulation.

Too stressed to think? A scoping review of the literature for healthcare educators utilising high acuity clinical scenarios

BACKGROUND

The practise of paramedicine can be highly stressful particularly where urgent lifesaving decisions need to be made. Traditionally, educators have adopted the approach of placing students in simulated stressful situations as a way of learning to cope with these challenges. It is unclear from the literature whether traditional stress inoculation enhances or hinders learning. This scoping review aims to identify and examine both the peer-reviewed and grey literature reporting physiological stress responses to high-acuity scenarios in paramedicine and cognate healthcare disciplines.

METHODS

Adhering strictly to JBI Evidence Synthesis Manual for conducting a scoping review, medical subject headings and areas, keywords and all other possible index terms were searched across EBSCOhost (Medline, CINAHL and APA PsycInfo), Scopus and, PubMed. English language articles both published (peer-reviewed academic papers, reports and conference proceedings) and unpublished (grey literature, Google Scholar reports) were included, and publications citing retrieved articles were also checked.

RESULTS

Searches performed across five electronic databases identified 52 articles where abstracts indicated potential inclusion. From this, 22 articles which reported physiological or psychophysiological responses to stressful scenario-based education were included.

CONCLUSION

This review identified that an acceptable level of stress during simulation can be beneficial, however a point can be exceeded where stress becomes a hinderance to learning resulting in underperformance. By identifying strategies to moderate the impact of acute stress, educators of paramedic and other healthcare students can utilise high-acuity clinical scenarios to their andragogical armamentarium which has the potential to improve real-world clinical outcomes.

Evolution of treatment for unspecific back pain: From past to future

Unspecific back pain (UBP) has long puzzled medical professionals. Historically, back pain (BP) was often attributed to mystical causes, treated with incantations or herbal concoctions. The Middle Ages shifted towards empirical practices, though still intertwined with superstition, using methods like leeches and bloodletting. The Renaissance introduced systematic healthcare approaches, laying the foundation for modern medicine. The 20th century saw significant advancements with diagnostic imaging, pharmacotherapy, physical therapy, and surgical interventions, though UBP remained elusive. Recent decades have seen a paradigm shift towards multidisciplinary approaches, addressing BP's multifactorial nature through holistic methods considering biomechanical, psychosocial, and lifestyle factors. This shift integrates quantitative research with hermeneutic interpretation, emphasizing evidence-based guidelines. Non-pharmacological interventions such as exercise therapy, electrotherapy, cognitive behavioral therapy, and mindfulness-based stress reduction have gained prominence, empowering individuals in their recovery. Technological innovations like virtual reality and artificial intelligence offer personalized treatment plans, optimizing outcomes. The future of BP treatment holds promise with advancements in regenerative medicine, neuromodulation, telemedicine, and remote monitoring platforms, enhancing accessibility and continuity of care, especially in underserved communities. However, challenges such as the opioid epidemic and healthcare disparities remain, necessitating judicious prescribing practices and equitable resource distribution. The evolving treatment landscape for UBP reflects the dynamic interplay between scientific progress, clinical innovation, and societal needs, aiming to alleviate the burden of back pain and improve quality of life.

Pediatric Monitoring Technologies and Congenital Heart Disease: A Systematic Review

Outpatient monitoring of infants with congenital heart disease has been shown to significantly reduce rates of mortality in the single ventricle population. Despite the accelerating development of miniaturized biosensors and electronics, and a growing market demand for at-home monitoring devices, the application of these technologies to infants and children is significantly delayed compared with the development of devices for adults. This article aims to review the current landscape of available monitoring technologies and devices for pediatric patients to describe the gap between technologies and clinical needs with the goal of progressing development of clinically and scientifically validated pediatric monitoring devices.

Risk Factors for Suicide Among Professional Athletes

BACKGROUND

Suicide is a major public health concern that affects all demographics. Risk factors for suicide in professional athletes are poorly understood compared with the general population. The goal of this study was (1) to explore the current literature on risk factors for suicide in the population of professional athletes and (2) to formulate a proposed suicide risk identification tool as the first step in the production of a validated screening method specific to this population.

METHODS

A comprehensive literature search for relevant publications was carried out through 7 databases.

RESULTS

There is some evidence to suggest that retirement, anabolic androgenic steroid use, sexual abuse victimization, health problems, financial issues, relationship issues, having immigrant parents, having a financially disadvantaged childhood, using self-blame or behavioral disengagement as a coping strategy, changes in appetite or weight, sleep problems, reduced competitiveness, and thinking about a career after retirement are potential risk factors for suicide in this population. There is limited evidence to suggest that having a career in elite or professional sports, participation in contact sports, and participating in specific sports that are not associated with a higher suspected prevalence of performance-enhancing drug use are potential risk factors.

CONCLUSIONS

This study identified potential risk factors for suicide among elite and professional athletes. These findings were used to help formulate a proposed suicide risk identification tool. Future research is recommended to explore and clarify specific risk factors for suicide in this population and to test the validity of the proposed tool.

How-To Create an Orthopaedic Systematic Review: A Step-by-Step Guide. Part III: Executing a Meta-Analysis

At the top of the evidence-based pyramid, systematic reviews stand out as the most powerful, synthesizing findings from numerous primary studies. Specifically, a quantitative systematic review, known as a meta-analysis, combines results from various studies to address a specific research question. This review serves as a guide on how to: (1) design; (2) perform; and (3) publish an orthopedic arthroplasty systematic review. In Part III, we focus on how to design and perform a meta-analysis. We delineate the advantages and disadvantages of meta-analyses compared to systematic reviews, acknowledging their potential challenges due to time constraints and the complexities posed by study heterogeneity and data availability. Despite these obstacles, a well-executed meta-analysis contributes precision and heightened statistical power, standing at the apex of the evidence-based pyramid. The design of a meta-analysis closely mirrors that of a systematic review, but necessitates the inclusion of effect sizes, variability measures, sample sizes, outcome measures, and overall study characteristics. Effective data presentation involves the use of forest plots, along with analyses for heterogeneities and subgroups. Widely-used software tools are common in this domain, and there is a growing trend toward incorporating artificial intelligence software. Ultimately, the intention is for these papers to act as foundational resources for individuals interested in conducting systematic reviews and meta-analyses in the context of orthopaedic arthroplasty, where applicable.

Preventive health measures in small and medium-sized enterprises: A scoping review on implementation strategies

OBJECTIVE

To describe implementation strategies for preventive health measures in SMEs and the effectiveness of the strategies on implementation outcomes.

METHODS

A literature search was performed in multiple electronic databases. Studies published between 2000 and 2021 that evaluated the implementation of preventive health measures in SMEs were included. Classification of implementation strategies was based on two complementary classification systems.

RESULTS

Nineteen studies, of which 5 RCTs were included. Eighteen distinct implementation strategies were reported. All studies applied a combination of implementation strategies, and nearly all reported a positive effect on one or more implementation outcomes: sustainability, acceptability, feasibility, penetration, fidelity, adoption, and appropriateness.

CONCLUSIONS

Overall, a positive effect of combined implementation strategies on the implementation outcome(s) was found. The 'distribution of educational materials' and 'provide ongoing consultation' combined show positive effects on sustainability.

Effects of a digital intervention on physical activity in adults: A randomized controlled trial in a large-scale sample

Background

Physical inactivity is associated with health risks, contributing to various diseases and all-cause mortality. Despite recommendations for regular physical activity (PA), many adults remain inactive, influenced by socioeconomic and environmental factors. Digital interventions, particularly web-based PA programs, offer promising possibilities to promote PA across populations. These programs vary in their effectiveness, reflecting differences in design, user engagement, and behavior change techniques employed.

Objective

This study evaluates the effectiveness of the 12-week multimodal web-based TKFitnessCoach. The PA online program is part of the TK-HealthCoach. This study investigates the program's impact on self-reported PA levels, goal attainment, healthrelated quality of life, body weight, and eating behavior, comparing an interactive personalized web-based intervention and non-interactive web-based health information.

Methods

In a randomized controlled trial (RCT), participants were allocated to either the intervention group (IG), receiving access to the interactive TK-FitnessCoach, or the control group (CG) that was provided a static website with evidence-based information on PA. The study targeted a German-speaking adult population interested in improving health behavior. Data was assessed at T0 (beginning of the study), T1 (postintervention), T2, 6 months, and T3, 12 months follow-ups, focusing on self-reported PA at T3 and on various secondary outcomes.

Results

We achieved equally distributed sociodemographics in both the IG and the CG with a mean age of 42.8 (IG), resp. 43.1 years (CG), and female participants of 76.1 % (IG), resp. 74.7 % (CG). PA at baseline was 277.9 min/week in the IG and 273.3 min/week in the CG. Both, the IG (n = 1153 in the Intention-to-treat (ITT) dataset) and CG (n = 1177 in the ITT dataset) exhibited significant increases in PA over time (IG(T3-T0) = 72.92 min/week; CG(T3-T0) = 74.12 min/week).However, the study did not find significant differences in the effectiveness of the interactive TK-FitnessCoach compared to the non-interactive control in terms of improving PA and related health outcomes. The intensity of using the TK-FitnessCoach was not associated with PA.

Conclusions

Both programs were effective in promoting PA among adults, with no significant differences observed between the two RCT groups. This highlights the potential of digital interventions in addressing physical inactivity, suggesting that the effectiveness of such programs may not solely depend on their interactivity but also on the quality and relevance of the information provided. Further research is needed to explore optimization strategies for such interventions, especially for persons with low PA, including user engagement, behavior change techniques, and the integration of objective PA tracking methods.

Effectiveness of low dose computed tomography to detect fractures in paediatric suspected physical abuse: a systematic review

PURPOSE

The skeletal survey X-ray series is the current 'gold standard' when investigating suspected physical abuse (SPA) of children, in addition to a non-contrast computed tomography (CT) brain scan. This systematic literature review synthesised findings of published research to determine if low dose computed tomography (LDCT) could detect subtle fractures and therefore replace the skeletal survey X-ray series in the investigation of SPA in children aged under 3 years.

METHODS

Five electronic databases and grey literature were systematically searched from their inception to 28 April 2022. Primary studies were included where the population comprised paediatric patients up to 16 years and LDCT was used to detect fractures associated with SPA. Studies involving imaging investigations of the head, standard dose CT examinations or accidental trauma were excluded.

RESULTS

Three studies met the inclusion criteria, all of which were case series. These studies did not report many of the criteria required to compare the accuracy of LDCT to X-ray, i.e. they did not meet the criteria for a diagnostic accuracy test. Therefore, it is difficult to conclude from the case series if LDCT is accurate enough to replace X-rays.

CONCLUSION

Due to the gap in current literature, a phantom study and subsequent post-mortem CT study are recommended as the primary investigative methods to assess the ability of low-dose CT to identify the subtle fractures associated with SPA and to calculate how low the achievable CT dose can be.

Effectiveness of dexmedetomidine on patient-centred outcomes in surgical patients: a systematic review and Bayesian meta-analysis

BACKGROUND

Dexmedetomidine is increasingly used for surgical patients requiring general anaesthesia. However, its effectiveness on patient-centred outcomes remains uncertain. Our main objective was to evaluate the patient-centred effectiveness of intraoperative dexmedetomidine for adult patients requiring surgery under general anaesthesia.

METHODS

We conducted a systematic search of MEDLINE, Embase, CENTRAL, Web of Science, and CINAHL from inception to October 2023. Randomised controlled trials (RCTs) comparing intraoperative use of dexmedetomidine with placebo, opioid, or usual care in adult patients requiring surgery under general anaesthesia were included. Study selection, data extraction, and risk of bias assessment were performed by two reviewers independently. We synthesised data using a random-effects Bayesian regression framework to derive effect estimates and the probability of a clinically important effect. For continuous outcomes, we pooled instruments with similar constructs using standardised mean differences (SMDs) and converted SMDs and credible intervals (CrIs) to their original scale when appropriate. We assessed the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Our primary outcome was quality of recovery after surgery. To guide interpretation on the original scale, the Quality of Recovery-15 (QoR-15) instrument was used (range 0-150 points, minimally important difference [MID] of 6 points).

RESULTS

We identified 49,069 citations, from which 44 RCTs involving 5904 participants were eligible. Intraoperative dexmedetomidine administration was associated with improvement in postoperative QoR-15 (mean difference 9, 95% CrI 4-14, n=21 RCTs, moderate certainty of evidence). We found 99% probability of any benefit and 88% probability of achieving the MID. There was a reduction in chronic pain incidence (odds ratio [OR] 0.42, 95% CrI 0.19-0.79, n=7 RCTs, low certainty of evidence). There was also increased risk of clinically significant hypotension (OR 1.98, 95% CrI 0.84-3.92, posterior probability of harm 94%, n=8 RCTs) and clinically significant bradycardia (OR 1.74, 95% CrI 0.93-3.34, posterior probability of harm 95%, n=10 RCTs), with very low certainty of evidence for both. There was limited evidence to inform other secondary patient-centred outcomes.

CONCLUSIONS

Compared with placebo or standard of care, intraoperative dexmedetomidine likely results in meaningful improvement in the quality of recovery and chronic pain after surgery. However, it might increase clinically important bradycardia and hypotension.

Navigating the uncommon: challenges in applying evidence-based medicine to rare diseases and the prospects of artificial intelligence solutions

The study of rare diseases has long been an area of challenge for medical researchers, with agonizingly slow movement towards improved understanding of pathophysiology and treatments compared with more common illnesses. The push towards evidence-based medicine (EBM), which prioritizes certain types of evidence over others, poses a particular issue when mapped onto rare diseases, which may not be feasibly investigated using the methodologies endorsed by EBM, due to a number of constraints. While other trial designs have been suggested to overcome these limitations (with varying success), perhaps the most recent and enthusiastically adopted is the application of artificial intelligence to rare disease data. This paper critically examines the pitfalls of EBM (and its trial design offshoots) as it pertains to rare diseases, exploring the current landscape of AI as a potential solution to these challenges. This discussion is also taken a step further, providing philosophical commentary on the weaknesses and dangers of AI algorithms applied to rare disease research. While not proposing a singular solution, this article does provide a thoughtful reminder that no 'one-size-fits-all' approach exists in the complex world of rare diseases. We must balance cautious optimism with critical evaluation of new research paradigms and technology, while at the same time not neglecting the ever-important aspect of patient values and preferences, which may be challenging to incorporate into computer-driven models.

Prevalence and predictors of radiographic pneumonia in children with wheeze: A systematic review and meta-analysis

BACKGROUND

Diagnostic uncertainty exists surrounding the identification of radiographic pneumonia in children with wheeze. It is important to determine the prevalence and clinical predictors of pneumonia in this population to limit chest radiography (CXR) and promote judicious antibiotic use.

OBJECTIVES

The objectives were to (1) estimate the prevalence of radiographic pneumonia in children with wheeze and (2) systematically review the diagnostic accuracy of clinical findings for the identification of radiographic pneumonia.

METHODS

Data sources were MEDLINE, PubMed Central, Cochrane Library, CINAHL, and Web of Science (January 1995 to September 2023). For study selection, two reviewers identified high-quality studies reporting on clinical characteristics associated with radiographic pneumonia in wheezing children (age 0-21 years). Using Covidence software, data regarding study characteristics, methodologic quality, and results were extracted. Data were pooled using random-effects meta-analysis.

RESULTS

A total of 8333 unique titles and abstracts were reviewed. Twelve studies, representing 7398 patients, were included. Fifteen percent of children with wheeze undergoing CXR had pneumonia. Findings associated with radiographic pneumonia included temperature ≥ 38.4°C (positive likelihood ratio [LR+] 2.1, 95% CI 1.2-3.6, specificity 85%), oxygen saturation < 92% (LR+ 3.6, 95% CI 1.4-8.9, specificity 89%), and grunting (LR+ 2.7, 95% CI 1.6-4.4, pooled specificity 91%). Factors associated with the absence of radiographic pneumonia included lack of fever (negative likelihood ratio [LR-] 0.67, 95% CI 0.52-0.85) and oxygen saturation ≥ 95% (LR- 0.64, 95% CI 0.42-0.98). Tachypnea and auscultatory findings were not associated with radiographic pneumonia.

DISCUSSION

Heterogeneity across studies limits generalizability. Additionally, all included studies overestimate the rate of radiographic pneumonia given the fact that all subjects had a CXR performed due to clinical suspicion of pneumonia.

CONCLUSIONS

Radiographic pneumonia occurs in 15% of wheezing children undergoing CXR for pneumonia. Auscultatory findings and tachypnea do not differentiate children with and without pneumonia, and the rate of radiographic pneumonia is very low in the absence of fever and hypoxemia.

Characteristics of Existing Online Patient Navigation Interventions: Scoping Review

BACKGROUND

Patient navigation interventions (PNIs) can provide personalized support and promote appropriate coordination or continuation of health and social care services. Online PNIs have demonstrated excellent potential for improving patient knowledge, transition readiness, self-efficacy, and use of services. However, the characteristics (ie, intervention type, mode of delivery, duration, frequency, outcomes and outcome measures, underlying theories or mechanisms of change of the intervention, and impact) of existing online PNIs to support the health and social needs of individuals with illness remain unclear.

OBJECTIVE

This scoping review of the existing literature aims to identify the characteristics of existing online PNIs reported in the literature.

METHODS

A scoping review based on the guidelines outlined in the Joanna Briggs Institute framework was conducted. A search for peer-reviewed literature published between 1989 and 2022 on online PNIs was conducted using MEDLINE, CINAHL, Embase, PsycInfo, and Cochrane Library databases. Two independent reviewers conducted 2 levels of screening. Data abstraction was conducted to outline key study characteristics (eg, study design, population, and intervention characteristics). The data were analyzed using descriptive statistics and qualitative content analysis.

RESULTS

A total of 100 studies met the inclusion criteria. Our findings indicate that a variety of study designs are used to describe and evaluate online PNIs, with literature being published between 2003 and 2022 in Western countries. Of these studies, 39 (39%) studies were randomized controlled trials. In addition, we noticed an increase in reported online PNIs since 2019. The majority of studies involved White females with a diagnosis of cancer and a lack of participants aged 70 years or older was observed. Most online PNIs provide support through navigation, self-management and lifestyle changes, counseling, coaching, education, or a combination of support. Variation was noted in terms of mode of delivery, duration, and frequency. Only a small number of studies described theoretical frameworks or change mechanisms to guide intervention.

CONCLUSIONS

To our knowledge, this is the first review to comprehensively synthesize the existing literature on online PNIs, by focusing on the characteristics of interventions and studies in this area. Inconsistency in reporting the country of publication, population characteristics, duration and frequency of interventions, and a lack of the use of underlying theories and working mechanisms to inform intervention development, provide guidance for the reporting of future online PNIs.

Functional outcomes and survival after total glossectomy with laryngectomy: a systematic review

Total glossectomy with laryngectomy (TGL) is a procedure with high morbidity/mortality risks reserved for cases of advanced tongue cancer with laryngeal invasion. This technique is controversial as there are significant impacts on quality of life, including loss of functional speech and swallowing. A systematic review was performed following the PRISMA guidelines with the primary goal of quantifying the functional outcomes and overall survival of patients undergoing TGL. The initial search resulted in 748 studies; seven of these met the inclusion criteria. Five studies evaluated functional speech postoperatively, and 12.1% (8/66) of patients in these studies achieved a form of functional speech. Most studies did not refer to the use of specific postoperative voice rehabilitation. Regarding swallowing function, 53.3% (32/60) of patients in five studies regained their ability to swallow. In six studies reporting gastrostomy tube dependence, 37.7% (29/77) of patients were tube-dependent. Recurrence within 1-year was reported in three studies; 52% (26/50) of the patients had recurrence within 1 year, and the 1-year disease-free survival rate was 48%. TGL is a highly invasive surgery; postoperatively, most patients do not regain the ability to speak, while only half are able to swallow. Despite these extreme efforts and sacrifices by the patient, approximately half of patients have a recurrence within the first year. The decision to perform a TGL should be made only in select and motivated patients after carefully explaining and weighing the oncological and quality of life risks and benefits.

Outcomes of Micropulse Laser Trabeculoplasty Compared to Selective Laser Trabeculoplasty: A Systematic Review and Meta-Analysis

Purpose

To perform a meta-analysis and systematic review to compare the efficacy and complications of micropulse laser trabeculoplasty (MLT) and selective laser trabeculoplasty (SLT) in adult patients with open-angle glaucoma (OAG) and ocular hypertension (OHT).

Methods

We performed a systematic review utilizing PubMed, Embase, and Scopus, on April 8, 2024. Meta-analyses were performed for the mean change in intraocular pressure (IOP) at one-month, six-month, and one-year follow-up visits, rate of IOP spikes (>5 mmHg increase from the pre-procedure baseline IOP), rate of treatment failure (<20% or <3 mmHg reduction in IOP or requiring additional medications or procedures), and mean change in number of medications.

Results

Six studies, with a total of 593 eyes, were included: 283 underwent MLT, while 310 underwent SLT. A statistically significant difference in the efficacy of MLT versus SLT at one-month and six-month follow-ups was present, with SLT reducing IOP by 0.83 mmHg (95% CI: 0.20, 1.47; P = 0.01) more and 0.55 mmHg (95% CI: 0.02, 1.08; P = 0.04) more than MLT, respectively. At the one-year follow-up, there was no significant disparity in IOP reduction between SLT and MLT (WMD = 0.16; 95% CI: -0.40, 0.71; P = 0.58). There was a significantly lower rate of IOP spikes in the MLT treatment group (RR = 0.37; 95% CI: 0.16, 0.89; P = 0.03). There was no statistically significant difference in the rate of treatment failures (RR = 1.05; 95% CI: 0.68, 1.62; P = 0.84) or number of topical medications reduced (WMD = 0.06; 95% CI: -0.13, 0.26; P = 0.53).

Conclusion

While SLT may offer greater short-term reductions in IOP, it may be associated with more postoperative IOP spikes when compared to MLT. At one-year follow-up, there were no significant differences in IOP reduction or failure rates between the MLT and SLT groups.

A Scoping Review on the Effects of Kinesio Taping on Oropharyngeal Function Related to Swallowing and Feeding

Following the expansion of interdisciplinary communication among rehabilitative service providers, new techniques have been introduced for treating swallowing disorders. Kinesio taping (KT) is one of the recently noticed techniques in the rehabilitation of swallowing and feeding disorders. Given the novelty of this technique in research and practice, the present scoping review aimed to summarize the available evidence on the effects of KT on the oropharyngeal function related to swallowing, and to identify current knowledge gaps to guide future studies. The initial comprehensive search was conducted in the six databases in November 2022 and then was updated in June 2023. Studies were independently reviewed by two authors to exclude all types of reviews and study protocols, studies published only in an abstract form and also studies that used KT for improving voice and dysarthria symptoms. The methodology of the included studies was also critically appraised using Joanna Briggs Institute (JBI) standard tools by two authors. The results of the studies were categorized and reported based on their overall objectives. In final analysis, 21 articles were described. Study designs ranged from randomized control trials (RCTs) to the case reports. The effects of KT had been investigated on drooling, oral feeding skills of infants, immediate activation of swallowing muscles, and management of dysphagia in patients with stroke or cerebral palsy (CP). Although innovative approaches to use KT as a therapeutic method in swallowing disorders have been investigated in the studies, there are many methodological limitations that affected validity of the results. In general, it seems there is not enough evidence to add KT to the usual management of feeding and swallowing disorders yet. Further studies, therefore, are required to achieve more accurate conclusions in each of the objectives summarized in this study.

The Use of TheraBracelet Upper Extremity Vibrotactile Stimulation in a Child with Cerebral Palsy-A Case Report

Background

TheraBracelet is peripheral vibrotactile stimulation applied to the affected upper extremity via a wristwatch-like wearable device during daily activities and therapy to improve upper limb function. The objective of this study was to examine feasibility of using TheraBracelet for a child with hemiplegic cerebral palsy.

Methods

A nine-year-old male with cerebral palsy was provided with TheraBracelet to use during daily activities in the home and community settings for 1.5 years while receiving standard care physical/occupational therapy.

Results

The child used TheraBracelet independently and consistently except during summer vacations and elbow-to-wrist orthotic use from growth spurt-related contracture. The use of TheraBracelet did not impede or prevent participation in daily activities. No study-related adverse events were reported by the therapist, child, or parent.

Conclusion

Future research is warranted to investigate TheraBracelet as a propitious therapeutic device with focus on potential impact of use to improve the affected upper limb function in daily activities in children with hemiplegic cerebral palsy.

Muscle hypertrophy following acquired neurogenic injury: systematic review and analysis of existing literature

OBJECTIVES

Neurogenic muscle hypertrophy (NMH) is a rare condition characterized by focal muscle hypertrophy caused by chronic partial nervous injury. Given its infrequency, underlying mechanisms remain poorly understood. Inspired by two clinical cases, we conducted a systematic review to gain insights into the different aspects of NMH.

METHODS

We systematically searched online databases up until May 30, 2023, for reports of muscle hypertrophy attributed to acquired neurogenic factors. We conducted an exploratory analysis to identify commonly associated features. We also report two representative clinical cases.

RESULTS

Our search identified 63 reports, describing 93 NMH cases, to which we added our two cases. NMH predominantly affects patients with compressive radiculopathy (68.4%), negligible muscular weakness (93.3%), and a chronic increase in muscle bulk. A striking finding in most neurophysiological studies (60.0%) is profuse spontaneous discharges, often hindering the analysis of voluntary traces. Some patients exhibited features consistent with more significant muscle damage, including higher creatine phosphokinase levels, muscle pain, and inflammatory muscle infiltration. These patients are sometimes referred to in literature as "focal myositis." Treatment encompassed corticosteroid, Botulinum Toxin A, decompressive surgery, antiepileptic medications, and nerve blocks, demonstrating varying degrees of efficacy. Botulinum Toxin A yielded the most favorable response in terms of reducing spontaneous discharges.

INTERPRETATION

This systematic review aims to provide a clear description and categorization of this uncommon presentation of an often-overlooked neurological disorder. Though questions remain about the underlying mechanism, evidence suggests that aberrant fiber overstimulation along with increased workload that promotes focal damage may result in muscle hypertrophy. This may serve as a guide for therapeutic interventions.

Arthroscopic and endoscopic techniques for iliopsoas release in THA are safe and effective: a systematic review of the literature

BACKGROUND

Hip replacement surgery is highly effective in relieving pain and improving mobility in patients with various hip conditions. However, some patients develop groin pain after surgery, often due to iliopsoas impingement (IPI), which can be challenging to diagnose. Conservative treatments are initially recommended, but when these are not effective, surgical options may be considered. This study aims to evaluate the clinical outcomes, success and failure rates, revision rates, and complications associated with arthroscopic and endoscopic surgery for IPI, thereby providing a comprehensive understanding of the effectiveness and risks of these surgical interventions.

MATERIALS AND METHODS

A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, including a thorough search of five main databases: PubMed, Scopus, Embase, Medline, and Cochrane. Eligible articles were meticulously evaluated according to predefined criteria for levels of evidence (LoE), with retrospective studies assessed using the Coleman Methodology Score (mCMS). This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO).

RESULTS

Among the 16 included studies, 431 patients with 434 hips underwent either endoscopic or arthroscopic tenotomy. Both techniques showed favorable outcomes, with arthroscopic tenotomy demonstrating slightly higher success rates than endoscopic tenotomy. Common complications included mild pain and occasional infections, with recurrence observed in some cases. Both techniques offer direct visualization of prosthetic components and potential preservation of psoas function.

CONCLUSIONS

Arthroscopic and endoscopic iliopsoas tenotomy are effective treatments for alleviating symptoms and improving hip function in patients with IPI post-total hip arthroplasty (THA).

The Use of High-Dose Intravenous L-Ascorbate in Pain Therapy: Current Evidence from the Literature

INTRODUCTION

Pain is the most common reason for seeking medical treatment. Despite extensive research efforts and effective analgesics modulating pain, there is still a major therapeutic gap in addressing the root causes of pain. Pain is associated with tissue damage induced by oxidative stress and induction of inflammatory mediators following high consumption of antioxidants. The role of antioxidants in general, and the administration of L-ascorbate in particular, is still controversially discussed and underestimated in the daily clinical practice.

METHODS

The current literature on the therapeutic effect of L-ascorbate, ascorbic acid, and vitamin C on various pain conditions was evaluated against the background of evidence-based medicine. Those articles, obtained from systematic search in PubMed, were critically assessed and rated in terms of evidence level and methodological quality by two independent experts. The primary purpose of this work was to establish specific pain therapy guidance for intravenous L-ascorbate.

RESULTS

A PubMed search revealed 14 suitable articles comprising controlled clinical trials and meta-analyses. An additional ten publications could be identified via secondary literature. There is supporting evidence for the efficacy of ascorbate treatment in inflammatory pain conditions, in the complex regional pain syndrome, in post zoster neuralgia, in neuropathic pain, in post-operative pain conditions, and in tumor-related pain. However, the considered studies differ in the type of administration, in dosage, in duration of treatment, as well as in quality of research. Despite all study heterogeneity, it became evident that research of high scientific quality is in support of the efficacy of L-ascorbate in pain treatment.

DISCUSSION

Oxidative stress is present in almost all pain conditions. Because oral administration of most magistral formulas of vitamin C does not provide biological availability, parenteral administration should be preferred and can be supported by an oral dose with high bioavailability on days without intravenous treatment. L-ascorbate should be preferred for parenteral high dosage, rather than ascorbic acid, as it does not release acid valences under physiological conditions.

CONCLUSIONS

L-ascorbate is an effective, safe, and economically favorable integrative treatment option for various pain conditions, addressing the root cause of tissue damage and inflammatory mediator burst.

Can we encourage the endoscopic treatment for external snapping hip (ESH)? A systematic review of current concepts

BACKGROUND

Snapping hip syndrome (SHS) is characterized by snapping sensation and pain and affects up to 10% of the general population. External snapping hip syndrome (ESHS), the most common form, is often due to repetitive movements in sports or anatomical predispositions. Conservative treatment includes physiotherapy and corticosteroid injections, while surgery is considered if conservative measures fail. Open surgical techniques carry several risks, while modern arthroscopic techniques offer less invasive options, such as endoscopic iliotibial band release (ITB) and gluteus maximus tenotomy.

MATERIALS AND METHODS

A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence. The Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) was used to analyze the retrospective studies. This paper was registered in the International Prospective Registry of Systematic Reviews (PROSPERO).

RESULTS

Out of 9 included studies, 403 patients with 689 hips underwent endoscopic treatment. ITB release and his variations were the main surgical techniques. Gluteus maximus tenotomy was also used in some studies. Postoperative rehabilitation protocols varied. Patients generally experienced significant improvements in symptoms and functional outcomes, with low rates of recurrence (1.02%) and revision (0.15%). Complications were minimal.

CONCLUSIONS

Endoscopic treatment of ESH shows favorable results, improving functional outcomes and returning patients to pre-injury activity levels. Long-term efficacy and costeffectiveness need to be evaluated, emphasizing the importance of large-scale prospective randomized trials to clarify surgery's benefits in refractory ESH cases.

Digital transition in pathology lab: a survey from the Lombardy region

Objective

Digital pathology is an opportunity to revise the routine and old artisanal workflow, moving to standard operating procedures, quality control and reproducibility. Here the results of a survey promoted by the Coordinamento della Medicina di Laboratorio (CRC Med Lab) of the Lombardy region in Italy are reported to shed light on the current situation of digital adoption in the country.

Methods

The survey composed of 58 questions was sent to 60 pathology laboratories. The results were collected and most significant answers were reported and discussed.

Results

Answers were received from 57 (95%) laboratories, a minority organized in spoke-hub networks (16%) with a centralized processing phase (11%). Hybrid manual/computer-assisted traceability was prevalent (36%), with QR/barcode labeling starting within the pathology lab (23%). Different laboratory information systems (LIS) were employed, mostly with alert functions and/or multimedial file attachments (56% and 46%, respectively). The majority opted for a semi-automated tracking management (44, 77%) and 18 centers (32%) were partly digitizing the routine (¾ scanning < 25% of slides). Whole slide images were retained for 3.7 years in average; in-house blocks/slides archiving was still preferred (30, 53%), with 1838 (±1551) and 1798 (±1950) days (5 years) internal permanence for blocks and slides that are stored in out-source (mean turnaround time for return on-demand 3.7±2.1, range 1-10 days).

Conclusions

The advantages of digital pathology must be balanced against the challenges faced in the structural revision of the pathology workflow. This regional scouting can represent the foundation to build an efficient and connected digital pathology system in the territory.

Frostbite in the Pediatric Population: A Comprehensive Review and a Prospective Canadian Survey

INTRODUCTION

Frostbite in the pediatric population, where skeletal maturity has not been achieved, can have important repercussions on subsequent growth. Yet, the optimal management of frostbite injuries in children remains vague. This review aims to summarize the current evidence for frostbite management in children and understand Canadian practice trends on this topic.

METHODS

A review using Medline, Scopus, Web of Science, and gray literature was performed to identify relevant literature on the clinical manifestations, diagnostic methods, and treatment options in pediatric frostbite. An online survey was sent to plastic surgeons through the Canadian Society of Plastic Surgeons (CSPS) mailing list to further identify national practices and trends for pediatric frostbite management.

RESULTS

A total of 109 articles were reviewed. No article provided a specific algorithm for pediatric frostbite, with existing recommendations suggesting the use of adult guidelines for treating children. Our survey yielded 9 responses and highlighted the rarity of pediatric frostbite cases, with no responder treating more than 10 cases per year. Most (55.6%) do not use a pediatric-specific treatment algorithm, whereas 30% apply adult guidelines. A conservative approach focusing on rewarming (55.6%), limb elevation (50%), and tetanus status verification (66.7%) was predominant. Imaging and surgical interventions seem to be reserved for severe cases.

CONCLUSIONS

The current literature for pediatric frostbite management lacks specificity. Canadian practices vary, with a trend toward a conservative approach. The limited evidence and rarity of experience highlight the need for further research, ideally in a collaborative multicentric manner, to create a consensus for pediatric frostbite care.
