Grading quality of evidence and strength of recommendations: a perspective

Critiques of the Cass Review: Fact-Checking the Peer-Reviewed and Grey Literature

The Cass Review's final report, published in April 2024, made recommendations to the UK's National Health Service regarding structuring of services for minors with gender-related distress. It recommended cautious use of hormonal interventions in this population and use of research protocols. Some clinician-researchers disagree with the Cass Review's recommendations and have written critiques. A critique of the Cass Review posted on Yale Law School's website in July 2024 has received extensive media coverage. Its references identified three other critiques. In these papers, there were multiple claims that were incorrect or that lacked essential clarification/contextualization. These claims involved (1) the Cass Review's contents and processes; (2) the pediatric transgender healthcare evidence base; (3) existing clinical practice guidelines, including claims that there is international medical consensus; (4) evidence-based medical practice and guideline development; and (5) conclusions regarding the validity of the Cass Review's findings. The Cass Review's careful, balanced investigations and judgments were a comprehensive, evidence-based response to the controversies in this pediatric clinical arena. Recently-published critiques of the Review have contained incorrect or inadequately contextualized claims. Because accurate information about medical interventions is essential to informed consent, it is important to correct errors in potentially influential publications.

The association between gonadectomy and timing of gonadectomy, and the risk of canine cranial cruciate ligament disease: A systematic review and meta-analysis

OBJECTIVE

To determine if gonadectomy in dogs is associated with the risk of cranial cruciate ligament disease (CrCLD) and to quantify the magnitude of the association.

STUDY DESIGN

Systematic review and meta-analysis.

SAMPLE POPULATION

Comparative studies with gonadectomized and entire dogs, with CrCLD as an outcome measure.

METHODS

A systematic search of the primary and gray literature was performed. The effect size of the outcome measure was defined as the OR and 95% CI. Subgroup analysis was performed with sex, breed, and age at gonadectomy. A pooled OR (95% CI) was generated from meta-analysis of relevant studies. Certainty in the body of evidence was rated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.

RESULTS

The literature search yielded 1398 results and 24 relevant studies were included for synthesis. Gonadectomized female (pooled OR = 2.293, 95% CI = 1.768-2.945) and male (pooled OR = 2.117, 95% CI = 1.665-2.691) dogs were both at increased odds of developing CrCLD in comparison with entire female and male dogs, respectively. Subgroup analysis showed that gonadectomy at 1 year or less was consistently associated with an increase in odds of developing CrCLD in both sexes. Overall certainty in the evidence was rated as moderate. All included studies were observational and no controlled trials were available.

CONCLUSION

In data with moderate certainty, gonadectomy is associated with increased odds of developing CrCLD in both sexes, particularly in dogs gonadectomized at 1 year of age or less.

CLINICAL SIGNIFICANCE

This study provides an estimate of the true effect size of gonadectomy on the odds of developing CrCLD, which may be useful for clinical decision making surrounding gonadectomy and the timing of gonadectomy.

Self-expanding metal stents versus decompression tubes as a bridge to surgery for patients with obstruction caused by colorectal cancer: a systematic review and meta-analysis

BACKGROUND

Using self-expanding metal stents (SEMS) and decompression tubes (DT) as a bridge-to-surgery (BTS) treatment may avoid emergency operations for patients with colorectal cancer-caused obstructions. This study aimed to evaluate the efficacy and safety of the two approaches.

METHODS

We systematically retrieved literature from January 1, 2000, to May 30, 2023, from the PubMed, Embase, Web of Science, SinoMed, Wanfang Data, Chinese National Knowledge Infrastructure, and Cochrane Central Register of Clinical Trials databases. Randomized controlled trials (RCTs) or cohort studies of SEMS versus DT as BTS in colorectal cancer obstruction were selected. Risks of bias were assessed for RCTs and cohort studies using the Cochrane Risk of Bias tool version 2 and Risk of Bias in Nonrandomized Studies of Interventions. Certainty of evidence was determined using the Graded Recommendation Assessment. Odds ratio (OR), mean difference (MD), and 95% confidence interval (95% CI) were used to analyze measurement data.

RESULTS

We included eight RCTs and eighteen cohort studies involving 2,061 patients (SEMS, 1,044; DT, 1,017). Pooled RCT and cohort data indicated the SEMS group had a significantly higher clinical success rate than the DT group (OR = 1.99, 95% CI 1.04, 3.81, P = 0.04), but no significant difference regarding technical success (OR = 1.29, 95% CI 0.56, 2.96, P = 0.55). SEMS had a shorter postoperative length of hospital stays (MD = - 4.47, 95% CI - 6.26, - 2.69, P < 0.00001), a lower rates of operation-related abdominal pain (OR = 0.16, 95% CI 0.05, 0.50, P = 0.002), intraoperative bleeding (MD = - 37.67, 95% CI - 62.73, - 12.60, P = 0.003), stoma creation (OR = 0.41, 95% CI 0.23, 0.73, P = 0.002) and long-term tumor recurrence rate than DT (OR = 0.47, 95% CI 0.22, 0.99, P = 0.05).

CONCLUSION

SEMS and DT are both safe as BTS to avoid emergency surgery for patients with colorectal cancer obstruction. SEMS is preferable because of higher clinical success rates, lower rates of operation-related abdominal pain, intraoperative bleeding, stoma creation, and long-term tumor recurrence, as well as a shorter postoperative length of hospital stays.

Cure rate of infections is not an argument for spacer in two-stage revision arthroplasty of the hip

INTRODUCTION

 A devastating complication after total hip arthroplasty (THA) is chronic periprosthetic joint infection (PJI). Most frequently spacers (Sp) with or without antibiotics are implanted in a two-stage procedure even though not always indicated due to unknown pathogen, femoral and acetabular defects or muscular insufficiency.

MATERIALS AND METHODS

 A retrospective analysis of a prospectively collected database was conducted, analyzing the treatment of 44 consecutive cases with chronic PJI undergoing two-stage revision using a Girdlestone situation (GS) in the interim period between 01/2015 and 12/2018. Diagnostics included intraoperative microbiological cultures, histological analysis, sonication of the initial implant, analysis of hip aspiration, as well as laboratory diagnostics and blood cultures. We analyzed the general and age-group-specific success rate of treatment using GS. Furthermore, we compared our data with the current literature on spacer implantation regarding common complications.

RESULTS

In total, 21 female and 23 male patients at a mean age of 59.3 ± 9.6 years were included. Age groups were divided into young, mid-age, and elderly. In most patients, microbiology revealed Staphylococcus epidermidis in 39.1% of cases, following Staphylococcus lugdunensis and Staphylococcus aureus in 10.9% after THA explantation. For histology, Krenn and Morawietz type 2 (infectious type) was diagnosed in 40.9%, type 3 (infectious and abrade-induced type) in 25.0%. With GS, the total cure rate was 84.1% compared to 90.1% (range 61-100%) using Sp as described in the literature. Among age-groups, cure rate varied between 77.8 and 100%. Other complications, which only occurred in the mid-age and elderly group, included the necessity of transfusion in 31.1%, and in total, one periprosthetic fracture was identified (2.3%).

CONCLUSION

GS shows an acceptable cure rate at a minimum of 2 years when compared to the cure rate reported in the literature for Sp without major complications. For patients with increased risks for treatment failure using spacer, GS seems to be an alternative for chronic PJI when looking at the success rate of treatment.

Efficacy of intraosseous access for trauma resuscitation: a systematic review and meta-analysis

BACKGROUND

During medical emergencies, intraosseous (IO) access and intravenous (IV) access are methods of administering therapies and medications to patients. Treating patients in emergency medical situations is a highly time sensitive practice; however, research into the optimal access method is limited and existing systematic reviews have only considered out-of-hospital cardiac arrest (OHCA) patients. We focused on severe trauma patients and conducted a systematic review to evaluate the efficacy and efficiency of intraosseous (IO) access compared to intravenous (IV) access for trauma resuscitation in prehospital care.

MATERIALS AND METHOD

PubMed, Web of Science, Cochrane Library, EMBASE, ScienceDirect, banque de données en santé publique and CNKI databases were searched for articles published between January 1, 2000, and January 31, 2023. Adult trauma patients were included, regardless of race, nationality, and region. OHCA patients and other types of patients were excluded. The experimental and control groups received IO and IV access, respectively, in the pre-hospital and emergency departments for salvage. The primary outcome was success rate on first attempt, which was defined as secure needle position in the marrow cavity or a peripheral vein, with normal fluid flow. Secondary outcomes included mean time to resuscitation, mean procedure time, and complications.

RESULTS

Three reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies; meta-analyses were then performed using Review Manager (Version 5.4; Cochrane, Oxford, UK). The success rate on first attempt was significant higher for IO access than for IV access (RR = 1.46, 95% CI [1.16, 1.85], P = 0.001). The mean procedure time was significantly reduced (MD = - 5.67, 95% CI [- 9.26, - 2.07], P = 0.002). There was no significant difference in mean time to resuscitation (MD = - 1.00, 95% CI [- 3.18, 1.17], P = 0.37) and complications (RR = 1.22, 95% CI [0.14, 10.62], P = 0.86) between the IO and IV groups.

CONCLUSION

The success rate on first attempt of IO access was much higher than that of IV access for trauma patients, and the mean procedure time of IO access was significantly less when compared to IV access. Therefore, IO access should be suggested as an urgent vascular access for hypotensive trauma patients, especially those who are under severe shock.

Evolution of total hip arthroplasty in patients younger than 30 years of age: A systematic review and meta-analysis

INTRODUCTION

While surgical technique and implant technology for total hip arthroplasty (THA) has improved over the years, it is unclear whether recent progress has translated to improved clinical outcomes for young patients. The goal of this study is to determine trends in (1) indications, (2) surgical technique (3) clinical and radiographic outcomes, and (4) survivorship for THA in patients younger than 30 years of age.

METHODS

MedLine, Cochrane, EMBASE, and Google Scholar were searched using several key phrases for articles focusing on THA performed on patients younger than 30 years of age between 1971 and 2020. A total of 34 qualifying articles were identified and stratified into three groups according to operative years and compared to one another on the basis of (1) indications; (2) fixation technique; (3) implant design; (4) clinical and radiographic outcomes; and (7) survivorship.

RESULTS

The mean patient age at index THA were 20.5 (9-30), 22.1 (11-30) and 21.5 (10-30) years, respectively, for each study group. Over time, patients underwent fewer THAs for JRA (Juvenile Rheumatoid Arthritis) (p < 0.001) but more for post-treatment and iatrogenic avascular necrosis (p < 0.001; p < 0.001). Early THAs primarily used metal on UHMWPE (Ultra high molecular weight polyethylene) (71.7%, p < 0.001), modern THA predominantly use ceramic on HXLPE (Highly cross-linked polyethylene) (42.5%, p < 0.001). Early fixation methods used cement (60.4%, p < 0.001), and modern fixation primarily use press fit technology (95.9%, p < 0.001). Prevalence of radiographic loosening decreased significantly (p < 0.001) over time. There was no significant difference in clinical improvement on HHS. Lastly, fewer patients required THA revision in recent decades (p < 0.001).

CONCLUSIONS

Advances in surgical technique and technology have served to improve implant longevity. Surprisingly, subjective clinical scores showed no significant improvement over time, suggesting that early iterations of THA were extremely successful.

Effectiveness of Training Programs for Reducing Adverse Psychological Outcomes in Parents of Children with Acquired Brain Injury: A Systematic Review and Meta-Analysis

INTRODUCTION

Parental stress following critical illness in their child has the potential to impact functional outcomes and quality of life for the child and whole family. Parent emotional functioning may also be an important clinical target to optimize child outcomes. This study assessed the effectiveness of training programs for parents aimed at reducing adverse psychological outcomes in parents of children with acute brain injury (ABI).

METHODS

We conducted searches of Embase, PubMed, Web of Science, and Cochrane Library to November 13, 2020. Randomized controlled trials (RCTs) that compared parent training programs with usual care, or an active comparator, and assessed psychological outcomes (depression, anxiety, stress) in parents of children with ABI were included. Two reviewers independently extracted data on study characteristics, participants, interventions, outcome measures, and results before and after intervention. Risk of bias was assessed using the Cochrane risk-of-bias tool.

RESULTS

Four RCTs involving 318 parents of children with ABI were eligible for review. Compared with usual care or active comparator, parent training was associated with significant reduction in parent stress (four RCTs; standardized mean difference [SMD], - 0.32 on a numerical rating scale [95% CI, - 0.60, - 0.05]; I-squared = 7.5%, p = 0.356); significant reduction in parent depression (three RCTs; SMD, - 0.43 [95% CI, - 0.72, - 0.14]; I-squared = 0.0%, p = 0.393); and significant reduction in parent anxiety (two RCTs; SMD, - 0.63 [95% CI, - 1.05, - 0.21]; I-squared = 0.0%, p = 0.629). Overall risk of bias was high for randomization process (one RCT), missing outcome data (three RCTs), measurement of the outcome (three RCTs), and selection of reported result (two RCTs). Heterogeneity between studies by country of study origin was not significant.

CONCLUSIONS

Compared with usual care or an active comparator, parent training was associated with short-term reduction in stress, depression, and anxiety in parents of children with ABI. Future clinical trials of parent interventions are needed as there may be some short-term beneficial effects.

Evaluation of US Food and Drug Administration Drug Label Recommendations for Coadministration of Antivirals and Acid-Reducing Agents

Coadministration with acid-reducing agents (ARAs), including proton pump inhibitors (PPIs), histamine H2 -receptor antagonists (H2 blockers), and antacids has been demonstrated to reduce antiviral exposure and efficacy. Therefore, it is essential that US Food and Drug Administration (FDA) drug labels include recommendations to manage these drug-drug interactions (DDIs). This investigation analyzed information in FDA drug labels to manage DDIs between ARAs and antivirals approved from 1998 to 2019. To ascertain clinical adoption, we assessed whether FDA label recommendations were incorporated into current antiviral clinical practice guidelines. We identified 82 label recommendations for 43 antiviral approvals. Overall, 56.1% of recommendations were deemed clinically actionable, with the most common actionable management strategies being dose adjustment during coadministration (40.2%) and coadministration not recommended (9.8%). The sources informing DDI recommendations were clinical DDI studies (59.8%) and predictions of altered exposure (40.2%). Antivirals with low aqueous solubility were more likely to have label recommendations and were more commonly investigated using clinical DDI studies (P < 0.01). For recommendations informed by clinical DDI studies, changes in drug exposure were associated with actionable label recommendations (P < 0.01). The frequency of exposure changes in clinical DDI studies was similar across antiviral indications, but exposure changes were numerically higher for antacids (71.4%) relative to PPIs (42.9%) and H2 blockers (28.6%). Of DDI pairs identified within drug labels, 76.8% were included in guidelines, and recommended management strategies were concordant in 90.5% of cases. Our findings demonstrate that current regulatory oversight mostly (but not completely) results in actionable label recommendations to manage DDIs for high-risk antivirals.

Early drain removal and late drain removal in patients after pancreatoduodenectomy: A systematic review and meta-analysis

Whether early or late drain removal (EDR/LDR) is better for patients after pancreatic resection remains controversial. We aim to systematically evaluate the safety and efficacy of early or late drain removal in patients who undergo pancreatic resection. We searched seven databases from January 1, 2000, through September 2021, and included randomized controlled trials (RCTs) or observational studies comparing EDR vs. LDR in patients after pancreatic resection. We separately pooled effect estimates across RCTs and observational studies. Finally, we included 4 RCTs with 711 patients and 8 nonRCTs with 7207 patients. Based on the pooled RCT data, compared to LDR, EDR reduced hospital length of stay (LOS) (RR: -2.59, 95% CI: -4.13 to -1.06) and hospital cost (RR: -1022.27, 95% CI: -1990.39 to -54.19). Based on the pooled nonRCT data, EDR may reduce the incidence of all complications (OR: 0.45, 95% CI: 0.32 to 0.63), pancreatic fistula (OR: 0.26, 95% CI: 0.15 to 0.45), wound infection (RR: 0.59, 95% CI: 0.06 to 5.45)), reoperation (OR: 0.62, 95% CI: 0.40 to 0.96) and hospital readmission (OR: 0.57, 95% CI: 0.47 to 0.69). There was an uncertain effect on mortality (OR from pooled nonRCTs: 1.02, 95% CI: 0.41 to 2.53) and delayed gastric emptying (RR from pooled RCTs: 0.76, 95% CI: 0.41 to 1.41). The findings of this meta-analysis suggest that early drain removal is associated with lower hospital cost, is safe and may reduce the incidence of complications compared to late drain removal in patients after pancreaticoduodenectomy.

Paper 2: a systematic review of narrative therapy treatment outcomes for eating disorders-bridging the divide between practice-based evidence and evidence-based practice

BACKGROUND

Narrative therapy has been proposed to have practice-based evidence however little is known about its research evidence-base in the treatment of eating disorders. The aim of this study was to conduct a systematic review of the outcome literature of narrative therapy for eating disorders.

METHOD

Treatment outcome data were extracted from 33 eligible included studies following systematic search of five data bases. The study is reported according to Preferred Reporting items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Of the identified 33 studies, 3 reported positive outcomes using psychometric instruments, albeit some were outdated. Otherwise, reported outcomes were based on therapy transcript material and therapist reports. The most commonly reported treatment outcome was in relation to shifts in identity narratives and improved personal agency with a trend towards under-reporting shifts in ED symptoms. Some improvements were reported in interpersonal and occupational engagement, reduced ED symptoms, and improved quality of life, however, there was an absence of standardized measures to support these reports.

CONCLUSIONS

This systematic review found limited support for narrative therapy in the treatment of eating disorders through practice-based evidence in clinician reports and transcripts of therapy sessions. Less is known about systematic treatment outcomes of narrative therapy. There is a need to fill this gap to understand the effectiveness of narrative therapy in the treatment of EDs through systematic (1) Deliveries of this intervention; and (2) Reporting of outcomes. In doing so, the research arm of narrative therapy evidence base will become more comprehensively known.

Kidney Damage and Stress Biomarkers for Early Identification of Drug-Induced Kidney Injury: A Systematic Review

INTRODUCTION

Acute kidney injury (AKI) resulting from nephrotoxic medication use is prominent in hospitalized patients and is attributable to overall increases in mortality and costs of care. Serum creatinine (SCr), the current standard for identifying drug-induced AKI (DIAKI) is often delayed in its response to kidney insult by 26-36 h.

OBJECTIVE

This systematic review seeks to evaluate the clinical utility of several novel kidney damage and stress biomarkers for the prediction/timely detection of DIAKI, in comparison with traditional methods.

METHODS

A systematic review of the CINAHL, Cochrane Library, Embase, and PubMed databases was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, for articles analyzing the use of β2-microglobulin (B2M), interleukin (IL)-18, kidney injury molecule-1 (KIM-1), liver-type fatty acid-binding protein (L-FABP), neutrophil gelatinase-associated lipocalin (NGAL), and tissue inhibitor of metalloproteinase-2 * insulin-like growth factor-binding protein 7 [TIMP-1]*[IGFBP-7], for identifying DIAKI. Primary outcomes included time to DIAKI diagnosis using traditional methods and the time to significant difference in biomarker concentrations between DIAKI and non-AKI study subjects. Secondary outcomes included biomarker concentrations at the time of significant difference between the AKI status groups.

RESULTS

Fifteen unique articles were identified from the literature search. Twelve studies consisted of strictly hospitalized patient populations and three studies included hospitalized patients and patients discharged to home treatment. No studies reported values for urine volume output. Seventy-three percent of studies reported earlier times to significant difference of novel biomarker concentrations between the AKI and non-AKI groups than diagnosis of DIAKI by SCr alone. Significant variation was observed for individual urine biomarker concentrations at time of significant difference between the AKI status groups.

CONCLUSIONS

All analyzed biomarkers showed potential for use as early clinical markers of DIAKI, however further consensus on threshold urine concentrations for DIAKI is needed for meaningful implementation of these biomarkers in clinical practice.

Ovulation induction and intrauterine insemination in women of advanced reproductive age: a systematic review of the literature

PURPOSE

The objective of this review is to define live birth rate (LBR) and clinical pregnancy rate (CPR) for women ≥ 40 undergoing ovulation induction (OI)/intrauterine insemination (IUI).

METHODS

A systematic review was performed in accordance with PRISMA guidelines using PubMed and Google Scholar. The primary and secondary outcomes of interest were LBR and CPR, respectively.

RESULTS

There were 636 studies screened of which 42 were included. In 8 studies which provided LBR for partner sperm, LBR/cycle ranged from 0 to 8.5% with majority being ≤ 4%. Cumulative LBR was 3.6 to 7.1% over 6 cycles with the majority of pregnancies in the first 4. In the four studies providing LBR for donor sperm cycles, LBR/cycle ranged from 3 to 7% with cumulative LBR of 12 to 24% over 6 cycles. The majority of pregnancies occurred in the first 6 cycles. There were three studies with LBR or CPR/cycle ≥ 1% for women ≥ 43. No studies provided data above this range for women ≥ 45. In 4 studies which compared OI/IUI and IVF, the LBR from IVF was 9.2 to 22% per cycle. In 7 studies which compared outcomes by stimulation protocol, no significant differences were seen.

CONCLUSION

For women ≥ 40 using homologous sperm, the highest probability of live birth is via IVF. However, if IVF is not an option, OI/IUI may be considered for up to 4 cycles in those using partner sperm or 6 cycles with donor sperm. For women > 45, OI/IUI is likely futile but a limited trial may be considered for psychological benefit while encouraging consideration of donor oocyte IVF or adoption. Use of gonadotropins does not appear to be more effective than oral agents in this age group.

Evidence and implication of interventions across various socioecological levels to address pre-exposure prophylaxis uptake and adherence among men who have sex with men in the United States: a systematic review

BACKGROUND

Pre-exposure prophylaxis (PrEP) represents a proven biomedical strategy to prevent HIV transmissions among men who have sex with men (MSM) in the United States (US). Despite the design and implementation of various PrEP-focus interventions in the US, aggregated evidence for enhancing PrEP uptake and adherence is lacking. The objective of this systematic review is to synthesize and evaluate interventions aimed to improve PrEP uptake and adherence among MSM in the US, and identify gaps with opportunities to inform the design and implementation of future PrEP interventions for these priority populations.

METHODS

We followed the PRISMA guidelines and conducted a systematic review of articles (published by November 28, 2021) with a focus on PrEP-related interventions by searching multiple databases (PubMed, MEDLINE, Web of Science and PsycINFO). Details of PrEP interventions were characterized based on their socioecological level(s), implementation modalities, and stage(s) of PrEP cascade continuum.

RESULTS

Among the 1363 articles retrieved from multiple databases, 42 interventions identified from 47 publications met the inclusion criteria for this review. Most individual-level interventions were delivered via text messages and/or apps and incorporated personalized elements to tailor the intervention content on participants' demographic characteristics or HIV risk behaviors. Interpersonal-level interventions often employed peer mentors or social network strategies to enhance PrEP adoption among MSM of minority race. However, few interventions were implemented at the community-, healthcare/institution- or multiple levels.

CONCLUSIONS

Interventions that incorporate multiple socioecological levels hold promise to facilitate PrEP adoption and adherence among MSM in the US given their acceptability, feasibility, efficacy and effectiveness. Future PrEP interventions that simultaneously address PrEP-related barriers/facilitators across multiple socioecological levels should be enhanced with a focus to tackle contextual and structural barriers (e.g., social determinants of health, stigma or medical mistrust) at the community- and healthcare/institution-level to effectively promote PrEP use for MSM of color.

The effect of probiotics on the clinical status of adult patients with atopic dermatitis: a systematic review

OBJECTIVES

To describe, through a literature review, the results and benefits of oral and topical probiotics for adult patients with atopic dermatitis.

DESIGN

A systematic review of articles published over a 13-year period was conducted to answer the following questions: (1) what information is given in the scientific literature concerning the use of probiotics in adult patients with atopic dermatitis? (2) Was there an improvement in the clinical status of the patients? (3) Was there a change in the microbial profile in patients after using such approaches? (4) Among the probiotics used, which was the most used in adult AD patients? (5) What was the average time of these interventions? (6) What were the outcomes?

RESULTS

Seven studies with different sample sizes, ranging from 16 to 109 patients, were included in this review. These studies were all clinical trials (7/7), and probiotics (7/7) was the model of intervention chosen. Probiotics showed a potential to relieve the symptoms of the study groups with a reduction of pruritus and SCORAD when compared to the placebo groups. However, their effectiveness varied according to the strain, period, and form of administration.

CONCLUSIONS

Many studies have demonstrated that probiotics improve the symptoms of atopic dermatitis and even its prevention. However, there is still much controversy and divergence concerning the real benefits. Despite this, probiotics have demonstrated a fair ability in improving AD adult patients' symptoms in terms of decreasing pruritus and severity related to SCORAD.

Water therapies (hydrotherapy, balneotherapy or aqua therapy) for patients with cancer: a systematic review

BACKGROUND

Water therapies as hydrotherapy, balneotherapy or aqua therapy are often used in the relief of disease- and treatment-associated symptoms of cancer patients. Yet, a systematic review for the evidence of water therapy including all cancer entities has not been conducted to date.

PURPOSE

Oncological patients often suffer from symptoms which in patients with other diseases are successfully treated with water therapy. We want to gather more information about the benefits and risks of water therapy for cancer patients.

METHOD

In May 2020, a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and PubMed) to find studies concerning the use, effectiveness and potential harm of water therapy on cancer patients.

RESULTS

Of 3165 search results, 10 publications concerning 12 studies with 430 patients were included in this systematic review. The patients treated with water therapy were mainly diagnosed with breast cancer. The therapy concepts included aqua lymphatic therapy, aquatic exercises, foot bathes and whole-body bathes. Outcomes were state of lymphedema, quality of life, fatigue, BMI, vital parameters, anxiety and pain. The quality of the studies was assessed with the AMSTAR2-instrument, the SIGN-checklist and the IHE-Instruments. The studies had moderate quality and reported heterogeneous results. Some studies reported significantly improved quality of life, extent of lymphedema, neck and shoulder pain, fatigue and BMI while other studies did not find any changes concerning these endpoints.

CONCLUSION

Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of water therapy on cancer patients is not possible.

Does 3D-assisted surgery of tibial plateau fractures improve surgical and patient outcome? A systematic review of 1074 patients

PURPOSE

The aim of this systematic review was to provide an overview of current applications of 3D technologies in surgical management of tibial plateau fractures and to assess whether 3D-assisted surgery results in improved clinical outcome as compared to surgery based on conventional imaging modalities.

METHODS

A literature search was performed in Pubmed and Embase for articles reporting on the use of 3D techniques in operative management of tibial plateau fractures. This systematic review was performed in concordance with the PRISMA-guidelines. Methodological quality and risk of bias was assessed according to the guidelines of the McMaster Critical Appraisal. Differences in terms of operation time, blood loss, fluoroscopy frequency, intra-operative revision rates and patient-reported outcomes between 3D-assisted and conventional surgery were assessed. Data were pooled using the inverse variance weighting method in RevMan.

RESULTS

Twenty articles evaluating 948 patients treated with 3D-assisted surgery and 126 patients with conventional surgery were included. Five different concepts of 3D-assisted surgery were identified: '3D virtual visualization', '3D printed hand-held fracture models', 'Pre-contouring of osteosynthesis plates', '3D printed surgical guides', and 'Intra-operative 3D imaging'. 3D-assisted surgery resulted in reduced operation time (104.7 vs. 126.4 min; P < 0.01), less blood loss (241 ml vs. 306 ml; P < 0.01), decreased frequency of fluoroscopy (5.8 vs. 9.1 times; P < 0.01). No differences in functional outcome was found (Hospital for Special Surgery Knee-Rating Scale: 88.6 vs. 82.8; P = 0.23).

CONCLUSIONS

Five concepts of 3D-assisted surgical management of tibial plateau fractures emerged over the last decade. These include 3D virtual fracture visualization, 3D-printed hand-held fracture models for surgical planning, 3D-printed models for pre-contouring of osteosynthesis plates, 3D-printed surgical guides, and intra-operative 3D imaging. 3D-assisted surgery may have a positive effect on operation time, blood loss, and fluoroscopy frequency.

The European Hernia Society Prehabilitation Project: a systematic review of patient prehabilitation prior to ventral hernia surgery

BACKGROUND

Ventral hernia repair is one of the most commonly performed surgical procedures worldwide. To reduce the risk of complications, patient prehabilitation has received increasing focus in recent years. To assess prehabilitation measures, this European Hernia Society endorsed project was launched. The aim of this systematic review was to evaluate the current literature on patient prehabilitation prior to ventral hernia repair.

METHODS

The strategies examined were optimization of renal disease, obesity, nutrition, physical exercise, COPD, diabetes and smoking cessation. For each topic, a separate literature search was conducted, allowing for seven different sub-reviews.

RESULTS

A limited amount of well-conducted research studies evaluating prehabilitation prior to ventral hernia surgery was found. The primary findings showed that smoking cessation and weight loss for obese patients led to reduced risks of complications after abdominal wall reconstruction.

CONCLUSION

Prehabilitation prior to ventral hernia repair may be widely used; however, the literature supporting its use is limited. Future studies evaluating the impact of prehabilitation before ventral hernia surgery are warranted.

Efficacy of Single-Pill, Triple Antihypertensive Therapy in Patients with Uncontrolled Hypertension: A Systematic Review and Meta-analysis

INTRODUCTION

Systemic arterial hypertension is the most common preventable risk factor for all causes of morbidity and mortality worldwide with a prevalence of 35-40% of the adults. Despite the wide variety of effective antihypertensive medications, most hypertensive patients remain uncontrolled. However, the combination of ACE inhibitor, diuretics, and calcium antagonist for the triple therapy in a single Pill Combination (SPC) is an efficient regimen in hypertension management. It is recommended by the ESH 2018 guideline, which offers better efficacy and compliance to treatment.

AIM

To evaluate the efficacy of perindopril/indapamide/amlodipine single-pill combination in patients with uncontrolled hypertension.

METHODS

We searched PubMed, Scopus, Web of Science, and Cochrane CENTRAL for relevant clinical trials. We conducted the risk of bias assessment using Cochrane's risk of bias tool. We performed the analysis of continuous data using mean difference (MD) and relative 95% confidence interval (CI), while dichotomous data were analyzed using risk ratio (RR) and relative 95% CI. We included the analysis of the following outcomes: systolic blood pressure (SBP), Diastolic blood pressure (DBP), Heart rate (HR), 24 h Ambulatory blood pressure monitoring (ABPM) for SBP, and 24 h ABPM for DBP.

RESULTS

We included six clinical trials. We found that the triple therapy significantly reduces SBP by 24 mmHg (MD = - 24.65 [22.41, 26.89], (P < 0.01)), DBP by 12 mmHg (MD = 12.41 [11.53, 13.29], (P < 0.01)), 24-h ABPM for SBP by 14 mmHg (MD = 14.08 [9.10, 19.05], (P < 0.01)), and ABPM 24 h DBP by 7 mmHg (MD = 7.01 [5.37, 8.65], (P < 0.01)). We noted no significant difference of the single pill on heart rate (MD = 0.81 [- 0.04, 1.67], (P = 0.06).

CONCLUSION

perindopril/indapamide/amlodipine is effective in reducing systolic and diastolic blood pressures by 24 and 12 mmHg respectively. Over 24 h, the combination reduced systolic and diastolic blood pressures by 14 and 7 mmHg respectively.

Upper-Body Post-activation Performance Enhancement for Athletic Performance: A Systematic Review with Meta-analysis and Recommendations for Future Research

BACKGROUND

Research on post-activation performance enhancement (PAPE) is dominated by lower-body conditioning activities/performance test complexes. Despite the contribution of the upper body to many sporting actions, no review on upper-body PAPE currently exists.

OBJECTIVES

The aim of this systematic review with meta-analysis was to provide a synthesis of the available research on the inclusion of upper-body PAPE conditioning activities to improve athletic performance.

METHODS

A review of the literature was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines, including a literature search of EBSCOhost, SPORTDiscus, PubMed and Google Scholar databases. A total of 127 studies were identified through database searches, and were assessed against the following criteria: (1) randomised controlled trial or pre-and-post study design; (2) studies explored the effects of prior voluntary muscle activity, and not electrically induced contractions, (3) evidence, or lack thereof, of PAPE was quantified by the monitoring of individual performance to commonly applied physical tests or sport-specific tasks; (4) conditioning activities and performance tests were primarily upper-body; (5) detailed description of a standardised warm-up; and (6) full-text versions of studies could be accessed in English language peer-reviewed journals. Studies were quality assessed for methodological quality via the PEDro scale and ranked accordingly.

RESULTS

Thirty-one studies met the inclusion criteria. Studies were classified into different conditioning activity modes: bench press variations, sport-specific (modified implement throws, swing-specific, cable pulley, elastic resistance, combination) and bodyweight activity. Acute performance enhancement in several movement-specific combinations was found. A meta-analysis revealed that bench press at  ≥ 80% one repetition maximum significantly (p = 0.03; ES = 0.31) improves subsequent power output in the ballistic bench throw at 30-40% one repetition maximum, following 8-12 min recovery. Additionally, sport-specific overweight implement throws improved subsequent throwing distance at competition weight by ~ 1.7-8.5%; ES = 0.14-0.33, following 3 min recovery. Sport-specific lighter weighted bat swings and swing-specific isometrics resulted in improved subsequent competition weight bat swing velocities, ranging from ~ 1.3-4.9%; ES = 0.16-0.57.

CONCLUSIONS

This review presents several upper-body movement-specific conditioning activities that could be considered by coaches and practitioners as part of complex or contrast training, or used in pre-competition warm-ups to acutely enhance performance.

Low back pain expert systems: Clinical resolution through probabilistic considerations and poset

OBJECTIVE

Proper diagnosis of Low Back Pain (LBP) is quite challenging in especially the developing countries like India. Though some developed countries prepared guidelines for evaluation of LBP with tests to detect psychological overlay, implementation of the recommendations becomes quite difficult in regular clinical practice, and different specialties of medicine offer different modes of management. Aiming at offering an expert-level diagnosis for the patients having LBP, this paper uses Artificial Intelligence (AI) to derive a clinically justified and highly sensitive LBP resolution technique.

MATERIALS AND METHODS

The paper considers exhaustive knowledge for different LBP disorders (classified based on different pain generators), which have been represented using lattice structures to ensure completeness, non-redundancy, and optimality in the design of knowledge base. Further the representational enhancement of the knowledge has been done through construction of a hierarchical network, called RuleNet, using the concept of partially-ordered set (poset) with respect to the subset equality (⊆) relation. With implicit incorporation of probability within the knowledge, the RuleNet is used to derive reliable resolution logic along with effective resolution of uncertainties during clinical decision making.

RESULTS

The proposed methodology has been validated with clinical records of seventy seven LBP patients accessed from the database of ESI Hospital Sealdah, India over a period of one year from 2018 to 2019. Achieving 83% sensitivity of the proposed technique, the pain experts at the hospital find the design clinically satisfactory. The inferred outcomes have also been found to be homogeneous with the actual or original diagnosis.

DISCUSSIONS

The proposed approach achieves the clinical and computational efficiency by limiting the shortcomings of the existing methodologies for AI-based LBP diagnosis. While computational efficiency (with respect to both time and space complexity) is ensured by inferring clinical decisions through optimal processing of the knowledge items using poset, the clinical acceptability has been ascertained reaching to the most-likely diagnostic outcomes through probabilistic resolution of clinical uncertainties.

CONCLUSION

The derived resolution technique, when embedded in LBP medical expert systems, would provide a fast, reliable, and affordable healthcare solution for this ailment to a wider range of general population suffering from LBP. The proposed scheme would significantly reduce the controversies and confusion in LBP treatment, and cut down the cost of unnecessary or inappropriate treatment and referral.

Peroneus longus tendon autograft has functional outcomes comparable to hamstring tendon autograft for anterior cruciate ligament reconstruction: a systematic review and meta-analysis

PURPOSE

This review aimed to assess whether peroneus longus tendon (PLT) autograft would have comparable functional outcomes and graft survival rates when compared to hamstring tendon (HT) autograft for anterior cruciate ligament (ACL) reconstruction.

METHODS

PubMed, Web of Science, Cochrane Library, Ovid (MEDICINE), and EMBASE databases were queried for original articles from clinical studies including the keywords: ACL reconstruction and PLT autograft. Studies comparing PLT autograft versus HT autograft were included in this analysis and the following data were extracted from studies meeting the inclusion criteria: graft diameter, functional outcomes (Tegner activity scale, Lysholm score, and International Knee Documentation Committee (IKDC) subjective score), knee laxity (Lachman test), and complications (donor site pain or paresthesia, graft failure). Besides, the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the Foot and Ankle Disability Index (FADI) pre-operation and at last follow-up were also compared among patients using PLT autograft. Meta-analysis was applied using Review Manager 5.3 and p < 0.05 was considered statistically significant.

RESULTS

Twenty-three studies including 925 patients with ACL reconstruction met inclusion criteria. Of these, 5 studies included a direct comparison of PLT autograft (164 patients) versus HT autograft (174 patients). No significant difference was observed between PLT and HT autografts for Tegner activity scale, Lachman test, donor site pain, or graft failure. However, PLT groups demonstrated better Lysholm score (mean difference between PLT and HT groups, 1.55; 95% CI 0.20-2.89; p = 0.02) and IKDC subjective score (mean difference between PLT and HT groups, 3.24; 95% CI 0.29-6.19; p = 0.03). No difference of FADI was found (n.s.) but AOFAS was slightly decreased at last post-operative follow-up for patients with PLT autograft compared with pre-operative scores (mean difference of 0.31, 95% CI 0.07-0.54, p = 0.01).

CONCLUSION

PLT autograft demonstrated comparable functional outcomes and graft survival rates compared with HT autograft for ACL reconstruction. However, a slight decrease in AOFAS score should be considered during surgical planning. Hence, the PLT is a suitable autograft harvested outside the knee for ACL reconstruction to avoid the complication of quadriceps-hamstring imbalance which can occur when harvesting autografts from the knee.

Relationship between GSTM1 and GSTT1 polymorphisms and HPV infection: a systematic review

Human Papillomavirus (HPV) is the most important risk factor for cervical cancer, although not the only one. The allelic polymorphism of enzymes acting on carcinogen metabolism has shown to influence the risk of both intraepithelial lesions and cervical carcinogenesis. Several studies found an association between GSTM1/GSTT1 null genotypes and risk of cancer. This research aimed to review studies addressing the relationship between GSTT1 and GSTM1 and HPV infection in women, with or without cervical pathologies. A database search was conducted in four databases - PubMed, LILACS, SciELO, and Virtual Health Library - using the following descriptors: Glutathione transferase, HPV, and Genetic polymorphism. In total, we found 319 studies. After screening titles and abstracts, 27 articles were selected for full-text read, among which 20 were excluded and 7 were included in the review. No study has exclusively approached the relationship between the virus and GSTM1/GSTT1 variants. However, studies investigating the association between single nucleotide polymorphisms (SNPs) and cervical lesions or cancer found a probable relationship between them and infections with high-risk oncogenic subtypes. Although inconclusive, GSTT1 null alleles were more common in women with more aggressive HPV than GSTM1.

A systematic review and meta-analysis of iliocapsularis muscle: an important landmark in orthopedic surgery

PURPOSE

Iliocapsularis (IC) is a small muscle overlying the capsule of the hip joint. Although recent attention is being given to this muscle by orthopedic surgeons who encounter it during the anterior approach to total hip arthroplasty, little is known about its anatomical features. The aim of this study was to review the anatomy of IC, and describe its' origin, insertion, blood supply, innervation, muscle fiber characteristics and size. The function, clinical relevance and comparative anatomy of IC were also appraised.

METHODS

Using Evidence-Based Anatomy methodology, electronic databases were searched with the terms "iliocapsularis", "iliacus minor", "iliotrochantericus", and "ilioinfratrochantericus" to identify eligible studies.

RESULTS

Six studies (n = 287 lower limbs) examining the anatomy of IC were included. The pooled prevalence (PP) of the IC was 98.7% (95% CI 96.5-100.0). It arises from the inferior facet of the anterior inferior iliac spine (AIIS) and attaches inferior to the lesser trochanter. Attached to the anteromedial capsule along its entire length, IC has the largest capsular contribution of any of the hip muscles (73.8 ± 27.3 × 16.1 ± 4.4 mm). Thus, it is an important landmark in anterior surgical approaches to the hip joint.

CONCLUSION

The anatomy of IC is becoming more relevant with the increasing use of anterior approaches to hip surgery. With attachments to the AIIS, the lesser trochanter as well as the length of the capsule, this muscle is an important landmark in total hip arthroplasty.

Association between sepsis survivorship and long-term cardiovascular outcomes in adults: a systematic review and meta-analysis

PURPOSE

We aimed to determine the association between sepsis and long-term cardiovascular events.

METHODS

We conducted a systematic review of observational studies evaluating post-sepsis cardiovascular outcomes in adult sepsis survivors. MEDLINE, Embase, and the Cochrane Controlled Trials Register and Database of Systematic Reviews were searched from inception until April 21st, 2021. Two reviewers independently extracted individual study data and evaluated risk of bias. Random-effects models estimated the pooled crude cumulative incidence and adjusted hazard ratios (aHRs) of cardiovascular events compared to either non-septic hospital survivors or population controls. Primary outcomes included myocardial infarction, stroke, and congestive heart failure; outcomes were analysed at maximum reported follow-up (from 30 days to beyond 5 years post-discharge).

RESULTS

Of 12,649 screened citations, 27 studies (25 cohort studies, 2 case-crossover studies) were included with a median of 4,289 (IQR 502-68,125) sepsis survivors and 18,399 (IQR 4,028-83,506) controls per study. The pooled cumulative incidence of myocardial infarction, stroke, and heart failure in sepsis survivors ranged from 3 to 9% at longest reported follow-up. Sepsis was associated with a higher long-term risk of myocardial infarction (aHR 1.77 [95% CI 1.26 to 2.48]; low certainty), stroke (aHR 1.67 [95% CI 1.37 to 2.05]; low certainty), and congestive heart failure (aHR 1.65 [95% CI 1.46 to 1.86]; very low certainty) compared to non-sepsis controls.

CONCLUSIONS

Surviving sepsis may be associated with a long-term, excess hazard of late cardiovascular events which may persist for at least 5 years following hospital discharge.

Endovascular Versus Open Surgical Repair for Ruptured Descending Aortic Pathologies: A Systematic Review and Meta-Analysis of Observational Studies

PURPOSE

Ruptured descending thoracic aorta (rDTA) is an harmful condition requiring emergent treatment. Thoracic endovascular aortic repair (TEVAR) is replacing the traditional open repair in the majority of descending thoracic aortic disease. An unanimous agreement regarding the optimal approach to treat rDTA has not been reached yet due to the lack of evidences supporting the improvement of long-term survival. The present meta-analysis of observational cohort studies aims to estimate the outcome of endovascular (TEVAR) versus surgical (OR) approach in the treatment of rDTA.

METHODS

Prisma Statement for performing and reporting meta-analysis has been used. MEDLINE, Scopus and the Cochrane Library databases were searched. A meta-analysis of observational cohort studies that examined the outcomes after OR and TEVAR for the management of rDTA was performed.

RESULTS

A total of 10,466 patients with rDTA were screened. Endovascular therapy was associated with a lower risk of in-hospital mortality compared with open repair (Risk Ratio[RR] 0.63; 95% CI0.57-0.70). The risk of stroke rate was not statistically different between endovascular versus open approach (RR0.86; 95% CI0.62-1.19). Endovascular treatment had benefits on paraplegia (RR0.70; 95% CI0.55-0.91) and other neurological complications (RR0.24; 95% CI0.10-0.56). TEVAR was associated with lower renal failure, cardiac complications and vascular injuries. Late mortality (Hazard Ratio[HR] 0.84; 95% CI0.63-1.13) and re-intervention rate (RR1.48; 95% CI0.80-2.74) were not significantly different between TEVAR and OR.

CONCLUSIONS

TEVAR seems to offer advantages in terms of early mortality and complications rate. Moreover, data on late mortality and re-intervention are encouraging to consider endovascular treatment comparable to open repair for acute thoracic aorta emergency on long-term follow-up.

EA3: A softmax algorithm for evidence appraisal aggregation

Real World Evidence (RWE) and its uses are playing a growing role in medical research and inference. Prominently, the 21st Century Cures Act—approved in 2016 by the US Congress—permits the introduction of RWE for the purpose of risk-benefit assessments of medical interventions. However, appraising the quality of RWE and determining its inferential strength are, more often than not, thorny problems, because evidence production methodologies may suffer from multiple imperfections. The problem arises to aggregate multiple appraised imperfections and perform inference with RWE. In this article, we thus develop an evidence appraisal aggregation algorithm called EA³. Our algorithm employs the softmax function—a generalisation of the logistic function to multiple dimensions—which is popular in several fields: statistics, mathematical physics and artificial intelligence. We prove that EA³ has a number of desirable properties for appraising RWE and we show how the aggregated evidence appraisals computed by EA³ can support causal inferences based on RWE within a Bayesian decision making framework. We also discuss features and limitations of our approach and how to overcome some shortcomings. We conclude with a look ahead at the use of RWE.

Primary and radiation induced skull base osteosarcoma: a systematic review of clinical features and treatment outcomes

PURPOSE

We aim to systematically review and summarize the demographics, clinical features, management strategies, and clinical outcomes of primary and radiation-induced skull-base osteosarcoma (SBO).

METHODS

PubMed, Scopus, and Cochrane databases were used to identify relevant articles. Papers including SBO cases and sufficient clinical outcome data were included. A comprehensive clinical characteristic review and survival analysis were also conducted.

RESULTS

Forty-one studies describing 67 patients were included. The median age was 31 years (male = 59.7%). The middle skull-base was most commonly involved (52.7%), followed by anterior (34.5%) and posterior (12.7%) skull-base. Headache (27%), exophthalmos (18%), and diplopia (10%) were common presenting symptoms. Sixty-eight percent of patients had primary SBO, while 25% had radiation-induced SBO. Surgery was the main treatment modality in 89% of cases. Chemotherapy was administered in 65.7% and radiotherapy in 50%. Median progression-free survival (PFS) was 12 months, and the overall 5-year survival was 22%. The five-year survival rates of radiation-induced SBO and primary SBO were 39% and 16%, respectively (P < 0.05).

CONCLUSION

SBO is a malignant disease with poor survival outcomes. Surgical resection is the primary management modality, in conjunction with chemotherapy and radiotherapy. Radiation-induced SBO has a superior survival outcome as compared to its primary counterpart. Complete surgical resection showed a statistically insignificant survival benefit as compared to partial resection.

The arcade of Frohse: a systematic review and meta-analysis

PURPOSE

The structure of the proximal margin of the superficial layer of the supinator muscle is of high interest to many researches. Its tendinous appearance, called the arcade of Frohse, may be clinically important because of its close relationship to the deep branch of the radial nerve passing beneath it and is considered to be the cause of several syndromes. Given the importance of this structure, we aimed to provide a comprehensive and evidence-based review with meta-analytic techniques.

MATERIALS AND METHODS

The meta-analysis was performed in adherence to the PRISMA guidelines. Three medical databases were searched in order to identify all potentially eligible articles. Included studies were assessed for quality and the extracted morphological and morphometric data from the relevant articles was analyzed with the use of random effects meta-analysis.

RESULTS

A total of 20 studies were included into this meta-analysis. The pooled prevalence of the arcade of Frohse was calculated to be 66% within the adult population and 0% in the fetuses. Other variations regarding the arcade of Frohse were identified as very rare. Analysis of the morphometric parameters revealed the average proportions to be 23.22 mm for the length, 11.05 mm for the width and the mean thickness is 0.67 mm.

CONCLUSIONS

The arcade of Frohse is a commonly found structure in adults and thoughtful knowledge of its texture and morphology is especially useful in neurology, neurosurgery, orthopedics, trauma surgery and hand surgery, because it is considered to be the most common source of compression for the deep branch of the radial nerve.

A Systematic Review of Associations Between Adverse Peer Experiences and Emotion Regulation in Adolescence

Adolescence is a developmental period marked by changes in cognition, emotion, and social relations. For example, sensitivity to social feedback increases as peer relationships become more important yet less stable, leaving adolescents vulnerable to experiences of peer victimization and rejection. Given that prefrontal brain regions responsible for regulatory abilities continue to mature during adolescence, the brain is especially susceptible to environmental influences. As such, exposure to adverse peer experiences may undermine emotion regulation development. Thus, the present review sought to elucidate the association between adverse peer experiences and emotion regulation in adolescence (i.e. age 12-17 years). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the literature assessing adverse peer experiences (victimization and rejection) and emotion regulation (including neurobiological, behavioral, cognitive levels of analysis) was conducted (Narticles included = 27). Results demonstrate that adverse peer experiences are negatively associated with emotion regulation processes, behaviorally and neurally. Although variability in definitions and measurement of constructs make nuanced comparisons between studies difficult, the present systematic review organizes this body of literature and discusses how promising theoretical perspectives, including the cognitive control of emotion model and social information processing theory, may help to explain this association. Finally, recommendations for future work to expand our understanding of these processes, and for intervention and prevention efforts (e.g., school-based violence prevention and socio-emotional learning programs, parenting practices) that may serve to ameliorate outcomes for youths facing adverse peer experiences and emotion dysregulation, are discussed.

The effect of dietary phytochemicals on nuclear factor erythroid 2-related factor 2 (Nrf2) activation: a systematic review of human intervention trials

We conducted a systematic review of human trials examining the effects of dietary phytochemicals on Nrf2 activation. In accordance with the PRISMA guidelines, Medline, Embase and CAB abstracts were searched for articles from inception until March 2020. Studies in adult humans that measured Nrf2 activation (gene or protein expression changes) following ingestion of a phytochemical, either alone or in combination were included. The study was pre-registered on the Prospero database (Registration Number: CRD42020176121). Twenty-nine full-texts were retrieved and reviewed for analysis; of these, eighteen were included in the systematic review. Most of the included participants were healthy, obese or type 2 diabetics. Study quality was assessed using the Cochrane Collaboration Risk of Bias Assessment tool. Twelve different compounds were examined in the included studies: curcumin, resveratrol and sulforaphane were the most common (n = 3 each). Approximately half of the studies reported increases in Nrf2 activation (n = 10); however, many were of poor quality and had an unclear or high risk of bias. There is currently limited evidence that phytochemicals activate Nrf2 in humans. Well controlled human intervention trials are needed to corroborate the findings from in vitro and animal studies.

Fidelity of Interventions to Reduce or Prevent Stress and/or Anxiety from Pregnancy up to Two Years Postpartum: A Systematic Review

INTRODUCTION

Intervention fidelity refers to whether an intervention is delivered as intended and can enhance interpretation of trial outcomes. Fidelity of interventions to reduce or prevent stress and anxiety during pregnancy and postpartum has yet to be examined despite inconsistent findings for intervention effects. This study systematically reviews use and/or reporting of intervention fidelity strategies in trials of interventions, delivered to (expectant) parents during pregnancy and postpartum, to reduce or prevent stress and/or anxiety.

METHODS

MEDLINE, Embase, CINAHL, PsychINFO, and Maternity and Infant Care were searched from inception to March 2019. Studies were included if they were randomised controlled trials including pregnant women, expectant fathers and/or partners during pregnancy, and/ or parents within the first two years postpartum. The National Institutes of Health Behavior Change Consortium checklist was used to assess fidelity across five domains (study design, provider training, delivery, receipt, enactment).

RESULTS

Sixteen papers (14 interventions) were identified. Average reported use of fidelity strategies was 'low' (45%), ranging from 17.5 to 76%. Fidelity ratings ranged from 22% for provider training to 54% for study design.

CONCLUSIONS

Low levels of intervention fidelity may explain previous inconsistent effects of stress and anxiety reduction interventions. Important methodological areas for improvement include intervention provider training, fidelity of comparator conditions, and consideration of non-specific treatment effects. Increased methodological rigour in fidelity enhancement and assessment will improve intervention implementation and enhance examination of stress and anxiety reduction and prevention interventions delivered during pregnancy and the postpartum.

Prevalence and types of inconsistencies in clinical pharmacogenetic recommendations among major U.S. sources

Clinical implementation of pharmacogenomics (PGx) is slow. Previous studies have identified some inconsistencies among clinical PGx recommendations, but the prevalence and types of inconsistencies have not been comprehensively analyzed among major PGx guidance sources in the U.S. PGx recommendations from the Clinical Pharmacogenetics Implementation Consortium, U.S. Food and Drug Administration drug labels, and major U.S. professional medical organizations were analyzed through May 24, 2019. Inconsistencies were analyzed within the following elements: recommendation category; whether routine screening was recommended; and the specific biomarkers, variants, and patient groups involved. We identified 606 total clinical PGx recommendations, which contained 267 unique drugs. Composite inconsistencies occurred in 48.1% of clinical PGx recommendations overall, and in 93.3% of recommendations from three sources. Inconsistencies occurred in the recommendation category (29.8%), the patient group (35.4%), and routine screening (15.2%). In conclusion, almost one-half of clinical PGx recommendations from prominent U.S. guidance sources contain inconsistencies, which can potentially slow clinical implementation.

Local antibiotics in primary hip and knee arthroplasty: a systematic review and meta-analysis

BACKGROUND

Infection is a truly devastating complication of total joint arthroplasty, causing most patients to undergo a revision surgery, and to bear significant psychological and financial burden. The purpose of this study is to systematically evaluate the literature to determine the efficacy and complication profile of local antibiotic application in primary total joint arthroplasty.

METHODS

All studies of primary total joint arthroplasty which assessed local antibiotics in any form other than antibiotic-impregnated cement as an intervention were included. Studies that reported at least one outcome related to infection and were available in full text in English were eligible for inclusion. Studies which included both primary and revision cases but did not report the stratified data for each type of surgery and studies on fracture populations were excluded.

RESULTS

A total of 9 studies involving 3,714 cases were included. The pooled deep infection rate was 1.6% in the intervention groups and 3.5% in the control groups. Meta-analysis revealed a RR of 0.53 (95%CI: 0.35-0.79, p = 0.002) with no heterogeneity (I² = 0%) for infection in the intervention groups. Meta-analysis revealed a non-significant reduction in superficial infection rates in the intervention groups; however, there was a significant increase in aseptic wound complications in the intervention groups.

CONCLUSION

Local antibiotic application results in a moderate reduction in deep infection rates in primary total joint arthroplasty, with no significant impact on superficial infection rates. However, local antibiotic application may be associated with a moderate increase in aseptic wound complications.

Impact of COVID-19 on neurological manifestations: an overview of stroke presentation in pandemic

Corona virus disease 2019 (COVID-19) pandemic has become a globally challenging issue after its emergence in December 2019 from Wuhan, China. Despite its common presentation as respiratory distress, patients with COVID-19 have also shown neurological manifestation especially stroke. Therefore, the authors sought to determine the etiology, underlying risk factors, and outcomes among patients with COVID-19 presenting with stroke. We conducted a systematic review of the electronic database (PubMed, Google Scholar, Scopus, Medline, EMBASE, and Cochrane library) using different MeSH terms from November 2019 to June 2020. A total of 39 patients with stroke from 6 studies were included. The mean age of our included patients was 61.4 ± 14.2 years. Majority of the patients (n = 36, 92.3%) with COVID-19 had ischemic stroke, 5.1% (n = 2) had hemorrhagic stroke, and 2.6% (n = 1) had cerebral venous thrombosis at the time of initial clinical presentation. Almost all of the patients presented had underlying risk factors predisposing to stroke which included diabetes mellitus, hyperlipidemia, hypertension, and previous history of cerebrovascular disease. 51.2% (n = 20) of the included patients infected with COVID-19 with stroke died, while remaining patients were either discharged home or transferred to a rehabilitation unit. Exploring the neurological manifestation in terms of stroke among patients with COVID-19 is a step towards better understanding of the virus, preventing further spread, and treating the patients affected by this pandemic.

Definitions, survey methods, and findings of patient satisfaction studies in teledermatology: a systematic review

Remote consultations likely will grow in importance if the COVID-19 pandemic continues. This review analyzes which methods of teledermatology patients prefer by categorizing how recent studies have defined satisfaction, conducted surveys and concluded patients respond to the different modalities of teledermatology. Using PubMed and Cochrane databases, we reviewed studies from April 5th, 2010 to April 5th, 2020 that included the search terms patient satisfaction and teledermatology. All studies that included patient satisfaction as an outcome were included, but studies not published in English were excluded. We examined domains of satisfaction, survey method, study characteristics (including patient population, country, age, study design and evidence score), findings and statistical comparisons. We thoroughly reviewed 23 studies. Definitions of satisfaction varied, but all concluded patients were satisfied with the live-interactive and store-and-forward modalities. The studies reveal that store-and-forward is appropriate for clinicians with established patients who require regular follow-up. Verified areas of care include treatment of chronic conditions, topical skin cancer therapy, wound monitoring, and post-procedural follow-up. Only four studies conducted statistical analyses. One of those studies compared patient preference for each modality of teledermatology with face-to-face dermatology. While this study reported high satisfaction with each mode of teledermatology, patients still preferred face-to-face. Favorable responses to remote diagnostic capabilities suggest that these offerings improve preference for teledermatology. With only one study evaluating preference between each modality and face-to-face dermatology, more studies should address the discrepancy. Surveys that cover all domains of satisfaction may improve assessments and identify where gaps in preference exist.

American thyroid association guidelines are inconsistent with Grading of Recommendations Assessment, Development, and Evaluations-A meta-epidemiologic study

OBJECTIVES

The Grading of Recommendations Assessment, Development, and Evaluations (GRADE) working group has recognized some scenarios in which strong recommendations may be supported by low-quality evidence, the so-called paradigmatic situations. The adherence to these paradigmatic situations by the American Thyroid Association (ATA) guidelines, however, remains unknown.

STUDY DESIGN AND SETTING

Clinical guidelines from the ATA were retrieved and deemed eligible if created using GRADE or the American College of Physicians (ACP) system. Reviewers, independently and in duplicate, assessed all strong recommendations based on low-quality evidence and judged their alignment with GRADE paradigmatic situations. The study was conducted at KER Unit Mexico.

RESULTS

A total of five clinical guidelines, one using the GRADE and four using the ACP system, were eligible for analysis. We assessed a total of 518 recommendations, of which 355 (69%) were labeled as "strong" and 163 (31%) as "weak". A total of 151 strong recommendations were based on low-quality evidence, of which 36 (24%) were congruent with one of the five GRADE paradigmatic situations, whereas 115 (76%) were not consistent with any paradigmatic situations and should have been categorized as weak (23% [26/115]) or best-practice recommendations (77% [89/115]).

CONCLUSION

ATA clinical guidelines are discordant with GRADE guidance. Future guidelines should carefully evaluate the quality of evidence and recognize its limitations when developing recommendations.

Impact and use of reviews and 'overviews of reviews' to inform clinical practice guideline recommendations: protocol for a methods study

INTRODUCTION

Guidelines are systematically developed recommendations to assist practitioner and patient decisions about treatments for clinical conditions. High quality and comprehensive systematic reviews and 'overviews of systematic reviews' (overviews) represent the best available evidence. Many guideline developers, such as the WHO and the Australian National Health and Medical Research Council, recommend the use of these research syntheses to underpin guideline recommendations. We aim to evaluate the impact and use of systematic reviews with and without pairwise meta-analysis or network meta-analyses (NMAs) and overviews in clinical practice guideline (CPG) recommendations.

METHODS AND ANALYSIS

CPGs will be retrieved from Turning Research Into Practice and Epistemonikos (2017-2018). The retrieved citations will be sorted randomly and then screened sequentially by two independent reviewers until 50 CPGs have been identified. We will include CPGs that provide at least two explicit recommendations for the management of any clinical condition. We will assess whether reviews or overviews were cited in a recommendation as part of the development process for guidelines. Data extraction will be done independently by two authors and compared. We will assess the risk of bias by examining how each guideline developed clinical recommendations. We will calculate the number and frequency of citations of reviews with or without pairwise meta-analysis, reviews with NMAs and overviews, and whether they were systematically or non-systematically developed. Results will be described, tabulated and categorised based on review type (reviews or overviews). CPGs reporting the use of the Grading of Recommendations, Assessment, Development and Evaluation approach will be compared with those using a different system, and pharmacological versus non-pharmacological CPGs will be compared.

Individualised developmental care for babies and parents in the NICU: Evidence-based best practice guideline recommendations

Advances in neonatal care have improved survival of premature and critically ill infants; and while rates of some long-term neurodevelopmental problems in survivors have improved, such as cerebral palsy, there are others such as learning and behavioural difficulties that have not. The goal of improving long term neurodevelopmental morbidity has led to an increased focus on improving developmental care not only in neonatal long term follow- up clinics but within the NICU itself to capture the period of earliest brain neuroplasticity. The application of a systematic approach to improve practice is considered the most effective strategy for implementing neuroprotective developmentally supportive care. The content of this paper incorporates evidence-based systematic reviews to guide clinicians in the application of developmentally supportive interventions.

Is Scientific Medical Literature Related to Endometriosis Treatment Evidence-Based? A Systematic Review on Methodological Quality of Randomized Clinical Trials

Background and objectives: Informed decision-making requires the ability to identify and integrate high-quality scientific evidence in daily practice. We aimed to assess whether randomized controlled trials (RCTs) on endometriosis therapy follow methodological criteria corresponding to the RCTs' specific level in the hierarchy of evidence in such details to allow the reproduction and replication of the study. Materials and Methods: Using the keywords "therapy" and "endometriosis" and "efficacy" three bibliographic databases were searched for English written scientific articles published from 1 January 2008 to 3 March 2018. Only the randomized clinical trials (RCTs) were evaluated in terms of whether they provided the appropriate level of scientific evidence, equivalent to level 1, degree 1b in the hierarchy of evidence. A list of criteria to ensure study replication and reproduction, considering CONSORT guideline and MECIR standards, was developed and used to evaluate RCTs' methodological soundness, and scores were granted. Three types of bias, namely selection bias (random sequence generation and allocation concealment), detection bias (blinding of outcome assessment), and attrition bias (incomplete outcome data) were also evaluated. Results: We found 387 articles on endometriosis therapy, of which 38 were RCTs: 30 double-blinded RCTs and 8 open-label RCTs. No article achieved the maximum score according to the evaluated methodological criteria. Even though 73.3% of the double-blinded RCTs had clear title, abstract, introduction, and objectives, only 13.3% provided precise information regarding experimental design and randomization, and also showed a low risk of bias. The blinding method was poorly reported in 43.3% of the double-blinded RCTs, while allocation concealment and random sequence generation were inadequate in 33.3% of them. Conclusions: None of the evaluated RCTs met all the methodological criteria, none had only a low risk of bias and provided sufficient details on methods and randomization to allow for the reproduction and replication of the study. Consequently, the appropriate level of scientific evidence (level 1, degree 1b) could not be granted. On endometriosis therapy, this study evaluated the quality of reporting in RCTs and not the quality of how the studies were performed.

Is GRADE the Right Choice for Clinical Practice Guidelines Developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation?

Clinical practice guidelines (CPGs), developed to inform clinicians, patients, and policy makers about what constitutes optimal clinical care, are one way of increasing implementation of evidence into clinical practice. Many factors must be considered by multidisciplinary guideline panels, including strength of available evidence, limitations of current knowledge, risks/benefits of interventions, patient values, and limited resources. Grading of Recommendations Assessment, Development and Evaluation (GRADE) is a framework for summarizing evidence that has been endorsed by many national and international organizations for developing CPGs. But is GRADE the right choice for CPGs developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF)? In this commentary, we will introduce GRADE, discuss its strengths and limitations, and address the question of what potential benefits GRADE might offer beyond existing methodology used by the AAO-HNSF in developing CPGs.

Effectiveness of corticosteroid in the treatment of dengue - A systemic review

Corticosteroids are used therapeutically for a broad spectrum of diseases including autoimmune, allergic and inflammatory diseases. However in trials, the evidence for using corticosteroids in dengue is inconclusive and the quality of evidence is low. This systemic review is conducted to review clinical trials on dengue and steroid therapy to identify the current strength and weakness of evidence for the use of corticosteroids. We searched MEDLINE/PUBMED and Google scholar for publications on steroid use in dengue and the relevant authors of the study were contacted for additional information, as required. This review includes thirteen studies enrolling 1293 children and adult participants. There was no evidence of viremia and no significant side effects after the administration of low and high doses of oral corticosteroids and high doses of intravenous corticosteroids. Beneficial therapeutic effects were seen in some studies, which used high doses or multiple doses of steroids. The effectiveness of corticosteroids in dengue is depended upon sustained therapeutic blood levels of corticosteroids for an adequate duration and using a steroid with higher receptor affinity. Further clinical trials using pharmacologically and immunologically accepted standard steroid protocols are warranted to validate this conclusion.

Laparoscopic hysterectomy for benign indications: clinical practice guideline

Purpose

Since the introduction of minimally invasive gynecologic surgery, the percentage of advanced laparoscopic procedures has greatly increased worldwide. It seems therefore, timely to standardize laparoscopic gynecologic care according to the principles of evidence-based medicine. With this goal in mind—the Dutch Society of Gynecological Endoscopic Surgery initiated in The Netherlands the development of a national guideline for laparoscopic hysterectomy (LH). This present article provides a summary of the main recommendations of the guideline.

Methods

This guideline was developed following the Dutch guideline of medical specialists and in accordance with the AGREE II tool. Clinically important issues were firstly defined and translated into research questions. A literature search per topic was then conducted to identify relevant articles. The quality of the evidence of these articles was rated following the GRADE systematic. An expert panel consisting of 18 selected gynecologists was consulted to formulate best practice recommendations for each topic.

Results

Ten topics were considered in this guideline, including amongst others, the different approaches for hysterectomy, advice regarding tissue extraction, pre-operative medical treatment and prevention of ureter injury. This work resulted in the development of a clinical practical guideline of LH with evidence- and expert-based recommendations. The guideline is currently being implemented in The Netherlands.

Conclusion

A guideline for LH was developed. It gives an overview of best clinical practice recommendations. It serves to standardize care, provides guidance for daily practice and aims to guarantee the quality of LH at an (inter)national level.

Supporting Students: A GRADE Analysis of the Research on Student Wellness and Classroom Mental Health Support

Recommendations derived from research evidence regarding program implementation in school-based mental health [SBMH] require knowledge of the intervention outcomes as well as the potential to translate program components into schools. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) analysis was applied to major areas of the SBMH literature in addressing the areas of effectiveness and the strength of recommendation in implementation. Nine areas were addressed: emotional intelligence, stigma reduction, mindfulness, anxiety, depression, addictions, suicide prevention, trauma, and eating disorders. Ninety-eight studies were retrieved across the nine areas. Effect sizes based on reported outcomes and estimates on the strength of recommendation were generated in each of the nine areas of interest. These results provide an overview of the quality of the evidence that will be of relevance to school personal in making program selections.

Guide to clinical practice guidelines: the current state of play

Introduction

Extensive research has been undertaken over the last 30 years on the methods underpinning clinical practice guidelines (CPGs), including their development, updating, reporting, tailoring for specific purposes, implementation and evaluation. This has resulted in an increasing number of terms, tools and acronyms. Over time, CPGs have shifted from opinion-based to evidence-informed, including increasingly sophisticated methodologies and implementation strategies, and thus keeping abreast of evolution in this field of research can be challenging.

Methods

This article collates findings from an extensive document search, to provide a guide describing standards, methods and systems reported in the current CPG methodology and implementation literature. This guide is targeted at those working in health care quality and safety and responsible for either commissioning, researching or delivering health care. It is presented in a way that can be updated as the field expands.

Conclusion

CPG development and implementation have attracted the most international interest and activity, whilst CPG updating, adopting (with or without contextualization), adapting and impact evaluation are less well addressed.
