Effects of Preoperative Chronic Steroid Use on Postoperative Outcomes in Orthopedic Surgery: A Systematic Review and Meta-Analysis.

Higher rates of postoperative complications have been found in preoperative chronic steroid users. However, the effects of preoperative chronic steroid use on outcomes in orthopedic surgery were unclear. We performed a systematic review of cohort studies examining the effects of chronic steroid use on postoperative outcomes following orthopedic surgery and searched PubMed, Embase, and CENTRAL through 29 April 2023. We included 17 studies with 1,546,562 patients. No increase in 30-day mortality (adjusted odds ratio (aOR) 1.40, 95% confidence interval (CI) 0.64-3.09) and composite thromboembolic events (aOR 1.61, 95% CI 0.99-2.63) but increases in 30-day overall complications (aOR 1.42, 95% CI 1.16-1.75), wound dehiscence (aOR 2.91, 95% CI 1.49-5.66), infectious complications (any infection (aOR 1.61, 95% CI 1.44-1.80), sepsis (aOR 2.07, 95% CI 1.34-3.21), superficial surgical site infection (SSI) (aOR 1.73, 95% CI 1.03-2.89) and deep SSI (aOR 1.96, 95% CI 1.26-3.05)), re-admission (aOR 1.62, 95% CI 1.48-1.77), both 30-day (aOR 1.28, 95% CI 1.03-1.59) and 1-year re-operation (aOR 1.78, 95% CI 1.09-2.92), pulmonary embolism (aOR 5.94, 95% CI 1.52-23.29), and deep vein thrombosis (aOR 2.07, 95% CI 1.24-3.46) were detected in preoperative steroid users. An increased risk of adverse outcomes following orthopedic surgery in chronic steroid users was found.

Systematic Review and Critical Appraisal of Urticaria Clinical Practice Guidelines: A Global Guidelines in Dermatology Mapping Project (GUIDEMAP).

BACKGROUND: Management of urticaria can be optimized with clinical practice guidelines (CPGs). However, the quality of recent urticaria CPGs remains unclear. OBJECTIVE: To identify and appraise urticaria CPGs worldwide published in the last 5 years. METHODS: A search for relevant urticaria CPGs was conducted between January 1, 2017, and May 31, 2022, using the following databases: MEDLINE, Embase, National Institute for Health and Care Excellence (NICE) Evidence Search, Guidelines International Network, ECRI Guidelines Trust, Australian Clinical Practice Guidelines, Trip Medical Database, and DynaMed. The included CPGs were critically appraised using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, Lenzer et al's red flags, and the Institute of Medicine (IOM) criteria of trustworthiness. RESULTS: We included 21 urticaria CPGs. Most guidelines reviewed treatment recommendations of chronic spontaneous urticaria. The majority of guidelines were from European and Asian countries with high and high-middle sociodemographic index, written in English, and openly accessible. Seventeen guidelines (81%) had at least 1 AGREE II domain rated poor quality. Applicability, rigor of development, and stakeholder involvement were the 3 AGREE II domains that scored the lowest across guidelines. Appraisal with Lenzer et al's red flags showed that 18 guidelines (86%) raised at least 1 red flag indicating potential bias. The top 3 domains raising red flags were: no inclusion of nonphysician experts/patient representative/community stakeholders, no or limited involvement of a methodologist in the evaluation of evidence, and lack of external review. Based on IOM's criteria of trustworthiness, 20 guidelines (95%) had 1 or more criteria that did not meet best practice standards. The 3 domains with the highest number of best practice standards not met were updating procedures, rating strength of recommendations, and external review. Guidelines scored highest for the AGREE II domains of defining scope and purpose and clarity of presentation, and had the most fully met IOM's best practice standard for articulation of recommendations. However, only 1 urticaria CPG by NICE was identified as rigorously developed across all 3 appraisal tools. CONCLUSIONS: The quality of urticaria CPGs in the last 5 years varied widely. Only the NICE urticaria guideline consistently demonstrated excellent quality, high trustworthiness, and low risk of bias. Use of a rigorous framework to rate certainty of evidence and grade strength of recommendation, involvement of methodologists, stakeholder engagement with external review, and clear guidance for updating can help improve the quality of future CPGs.

Advances in understanding of the pathogenesis and therapeutic implications of drug reaction with eosinophilia and systemic symptoms: an updated review.

Drug reaction with eosinophilia and systemic symptoms or drug-induced hypersensitivity syndrome (DRESS/DIHS) is one type of severe cutaneous adverse reaction (SCAR). It is featured by fever, widespread skin lesions, protracted clinical course, internal organ involvement, and possibly long-term autoimmune sequelae. The presence of high-risk human leukocyte antigen (HLA) alleles, hypersensitivity reaction after culprit drug ingestion, and human herpesvirus reactivation may all contribute to its complex clinical manifestations. Some recent studies focusing on the roles of involved cytokines/chemokines and T cells co-signaling pathways in DRESS/DIHS were conducted. In addition, some predictors of disease severity and prognosis were also reported. In this review, we provided an update on the current understanding of the pathogenesis, potential biomarkers, and the relevant therapeutic rationales of DRESS/DIHS.

Bidirectional associations between psoriasis and migraine: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: To evaluate the association between psoriasis and migraine. PATIENTS AND METHODS: MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched for relevant observational studies from their respective inception to May 1, 2022. A random-effects model meta-analysis was performed to calculate the risk estimates quantifying the associations between psoriasis and migraine. We also performed a sensitivity analysis by including only studies with adjusted risk estimates and a subgroup analysis according to the severity of psoriasis. RESULTS: We included 9 studies with 6,742,075 participants. The meta-analysis illustrated increased odds for prevalent migraine among patients with psoriasis (pooled OR: 1.69, 95% CI: 1.26-2.28) and increased odds for prevalent psoriasis among those with migraine (OR: 1.88, 95% CI: 1.32-3.67). A subgroup analysis of cohort studies demonstrated an increasingly higher risk of incident migraine in patients with mild psoriasis and severe psoriasis (IRR being 1.37 (95% CI 1.30-1.44) and 1.55 (95% CI 1.29-1.86), respectively). CONCLUSIONS: This meta-analysis revealed significant bidirectional associations between migraine and psoriasis. Greater severity of psoriasis appears to be associated with a higher risk of developing migraine. Clinicians should evaluate symptoms of migraine in patients with psoriasis and provide proper treatments.

Risk for incident suicidality among psoriasis patients: a systematic review and meta-analysis.

Previous meta-analyses have produced conflicting conclusions about suicidality risk among psoriasis patients. We aimed to update the evidence on the risk for the whole continuum of incident suicidality in psoriasis patients. We performed an update systematic review and meta-analysis and searched CENTRAL, PubMed, and Embase from January 1, 2017 to August 14, 2021 for relevant new cohort studies and incorporated new studies into our previous systematic review. Random-effects model meta-analysis was used to obtain pooled hazard ratio (HR) with 95% confidence interval (CI). Subgroup analysis was conducted according to age and disease severity. A total of 12 studies were included in this meta-analysis. We detected no significant differences in the risk for incident completed suicide (HR 1.33, 95% CI 0.91-1.95), suicide attempt (HR 1.22, 95% CI 0.96-1.56), suicidal behavior (HR 1.08, 95% CI 0.98-1.19), and suicide ideation (HR 1.74, 95% CI 0.99-3.06) between psoriasis patients and non-psoriatic controls. In the subgroup analysis based on age, an increased risk for incident suicide ideation was observed in pediatric subgroup (HR 1.50, 95% CI 1.12-2.03). The updated evidence suggests no increased risk for whole continuum of incident suicidality spectrum in psoriasis patients but an increased risk for incident suicide ideation among pediatric psoriasis patients. Involving mental health professionals may be crucial in psoriasis management especially in young patients.

Buschke-Ollendorff syndrome presenting with asymptomatic yellowish papules and leg length discrepancy: A case report.

Buschke-Ollendorff syndrome (BOS) is a rare, usually benign, autosomal dominant genetic disease affecting about 0.005% globally. BOS commonly manifests with asymptomatic connective tissue nevi, sometimes with sclerotic bone lesions like osteopoikilosis or melorheostosis. However, BOS may develop severe, symptomatic complications that require surgical intervention. Here we report a 9-year-8-month girl presenting with multiple nonpruritic, nonpainful skin plaques scattered around the trunk, buttocks, and bilateral legs. She had a history of right varus foot with inadequate plantar flexion. Upon visiting, obvious leg length discrepancy (LLD) was noted. Lesional biopsy revealed increased fibroblasts within dermal collagen bundles. Verhoeff-van Gieson stain revealed scattered foci of thickened elastic fibers between collagen fibers, especially in the mid-dermis. Radiographic examination of the lower extremities showed multiple small, round-to-oval shaped, radiopaque spots on the pelvic bones, femurs, tibiae, and both feet. Hyperostosis along the long axis with "dripping candle wax" appearance was characteristic of osteopoikilosis and melorheostosis. Genetic analysis showed heterozygous point mutation in exon 1 of LEMD3 gene (c.1323C>A, p.Y441X), confirming diagnosis of BOS. Sequential and epiphyseodesis were performed to correct LLD with a favorable outcome at 2-year follow-up. BOS associated with severe bone abnormalities is rare, but orthopedic surgical intervention can provide satisfactory outcome.

Systematic review and critical appraisal of psoriasis clinical practice guidelines: a Global Guidelines in Dermatology Mapping Project (GUIDEMAP).

BACKGROUND: Clinical practice guidelines (CPGs) developed with rigorous methods can help optimize clinical care for patients with psoriasis. OBJECTIVES: To conduct an updated systematic review and comprehensive critical appraisal of global psoriasis CPGs. METHODS: A search of MEDLINE and Embase for psoriasis CPGs published between 1 January 2015 and 31 March 2021 was performed. Other guideline repositories were also searched for relevant CPGs. Descriptive analysis was conducted to summarize included guidelines. Three critical appraisal tools were used to assess the quality of included CPGs: the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, Lenzer et al.'s red flags, and the US Institute of Medicine's (IOM) criteria of trustworthiness. RESULTS: We included 33 psoriasis CPGs, with 25 openly accessible. Most CPGs were from high sociodemographic index countries in North America and Europe. Five CPGs received 'excellent quality' appraisals across all six AGREE II domains. Stakeholder involvement, rigour of development and applicability were the three domains with the lowest appraisal scores for AGREE II. Twenty-two CPGs raised at least one red flag indicative of potential bias. By the IOM's standards, external review of the guideline draft prior to publication and clear updating procedures were most often not addressed by guidelines, and only three CPGs were assessed as having higher overall trustworthiness. CONCLUSIONS: Most psoriasis guidelines were unable to consistently demonstrate high quality across multiple appraisal tools. The EuroGuiDerm guideline on the systemic treatment of psoriasis vulgaris was the only CPG to receive 'excellent quality' across all six AGREE II domains, to raise no Lenzer's red flags, and to have higher trustworthiness by IOM criteria.

One-Year Mortality Risk Stratification in Patients Hospitalized for Acute Decompensated Heart Failure: Construction of TSOC-HFrEF Risk Scoring Model.

BACKGROUND: Most previous risk prediction models in patients hospitalized for heart failure (HF) are derived from populations in Western countries, and it is unclear whether these models are applicable to Asian populations. This study aimed to construct a risk score system for predicting one-year mortality risk in Asian patients and to compare the applicability of this risk score system with the 3C-HF score system. METHODS: We used the population in the Taiwan Society of Cardiology-Heart Failure with Reduced Ejection Fraction (TSOC-HFrEF) registry, which is a prospective cohort of patients admitted for acute decompensated heart failure (ADHF) in Taiwan. The risk score system was constructed using multivariate Cox-model derived coefficients. A bootstrapping procedure was also used for bias-corrected evaluations. Comparisons between this constructed model and the 3C-HF score prediction model were evaluated using calibration plots and area under curve (AUC)/receiver operating characteristic (ROC) curve. RESULTS: Patients with complete data (n = 1127) in the TSOC-HFrEF registry were analyzed. During one year of follow-up, 14.5% (n = 163) of the patients died. A risk score system was constructed with the following predictors: body mass index, diastolic blood pressure, dyslipidemia, diabetes, aortic regurgitation, QRS duration, hemoglobin concentration, and digoxin usage. Compared to the 3C-HF score system, this risk score system had a similar discriminatory ability (AUC/ROC values of 0.675 and 0.636, p = 0.127) and both were well-calibrated in the Taiwan population. CONCLUSIONS: The proposed risk score system for predicting one-year all-cause mortality in Taiwanese patients with ADHF may facilitate risk stratification in Asian patients with HF.
