Abstract Aim To appraise the current evidence on the efficacy and safety of lamotrigine (LAM) in the treatment of pediatric mood disorders (PMD) (i.e., Major Depressive disorder [MDD], bipolar disorder [BD]). Methods Major databases were searched for randomized controlled trials (RCTs), open‐label trials, and observational studies reporting on pediatric (age < 18 years) patients treated with LAM for mood disorders. Results A total of 3061 abstracts were screened and seven articles were selected for inclusion. Seven studies (319 BD and 43 MDD patients), including one RCT ( n = 173), three prospective ( n = 105), and three retrospective ( n = 84) studies, met the study criteria with a study duration range from 8 to 60.9 weeks. The mean age of this pooled data is 14.6 ± 2.0 years. LAM daily dosage varied from 12.5 to 391.3 mg/day among the studies. In an important finding, the RCT reported favorable outcomes with LAM (HR = 0.46; p = 0.02) in 13‐ to 17‐year‐old age group as compared with 10‐ to 12‐year‐old age group (HR = 0.93; p = 0.88). In addition, time to occurrence of a bipolar event trended toward favoring LAM over placebo. All the studies identified LAM as an effective and safe drug in PMDs especially, BDs. Overall, LAM was well tolerated with no major significant side effects and no cases of Stevens–Johnson syndrome. Conclusions Most studies suggested that LAM was safe and effective in pediatric patients with mood disorders. However, the data regarding the therapeutic range for LAM are lacking. Based on the data, there is inconsistent evidence to make conclusive recommendations on therapeutic LAM dosage for mood improvement in the pediatric population. Further studies including larger sample sizes are required to address this relevant clinical question.

Abstract Introduction Indigenous North Americans have the highest cigarette smoking prevalence among all racial and ethnic groups in the United States. We seek to identify effective components of smoking cessation interventions in Indigenous people in the United States associated with favorable cessation outcomes. Methods A review of literature studying smoking cessation interventions in Indigenous North Americans (American Indians and Alaska Natives) from January 2010 through August 2021 was completed. The primary objective of this study was to identify components of interventions associated with positive smoking cessation outcomes in Indigenous people. The studies identified were synthesized in a meta-narrative approach. Results Ten studies out of 608 titles were included (6 randomized trials, 2 single-arm studies, 1 cohort study, and 1 prospective observational study). Five categories of smoking cessation interventions were identified; phone or web-based tools, culturally-tailored interventions, the inclusion of Indigenous study personnel, pharmaceutical cessation aids, and behavioral health interventions. Phone and web tools, cultural tailoring, and inclusion of Indigenous personnel conditions inconsistently influenced smoking cessation. Pharmaceutical aids were viewed favorably among participants. Individualized behavioral counseling sessions were effective at promoting smoking cessation, as was input from local communities in the planning and implementation phases of study. Conclusion A successful smoking cessation intervention in Indigenous North Americans includes Tribal or community input in intervention design and implementation; should provide individualized counseling sessions for participants, and offer access to validated smoking cessation tools including pharmacotherapy. Implications This study identifies a paucity of smoking interventions utilizing standard of care interventions in Indigenous North Americans. Standard of care interventions including individualized cessation counseling and pharmacotherapy were effective at promoting cessation. The use of novel culturally tailored cessation interventions was not more effective than existing evidence-based care with the exception of including Tribal and local community input in intervention implementation. Future smoking cessation interventions in Indigenous North Americans should prioritize the use of standard of care cessation interventions.

AbstractBackgroundThere is insufficient evidence regarding postoperative systemic antibiotic prophylaxis use for more than 24 h following cardiovascular implantable electronic devices (CIED) implantation and its impact on infection prevention. However, this strategy remains a common practice in many institutions.MethodsWe conducted a systematic review and meta‐analysis including studies that compared the outcomes of patients: (1) who received preoperative plus 24 h or more of postoperative antibiotic prophylaxis (intervention group); and (2) who received either preoperative only or preoperative plus less than 24 h of antibiotic prophylaxis (control group). Risk of bias was assessed with ROBINS‐I and ROB‐2 tools. Risk ratio (RR) was pooled using random‐effect meta‐analyses with inverse variance method.ResultsEight studies that included two randomized controlled trials (RCTs) and six cohort studies with a total of 26,187 patients were included in the analysis. Overall, there were no differences in outcomes between the two groups, which included rates of CIED infection (RR 0.77, 95% CI 0.42, 1.42), mortality (RR 1.19, 95% CI 0.69, 2.06), pocket hematoma (RR 1.15, 95% CI 0.44, 3.00) or reintervention (RR 0.87, 95% CI 0.22, 3.46). Of note, the results were primarily impacted by the larger RCT.ConclusionsThere was no benefit of postoperative antibiotic prophylaxis for more than 24 h following CIED implantation in the current systematic review and meta‐analysis. This supports the practice advocated by current guidelines which foster antibiotic stewardship and may result in reductions of adverse drug events, selection for antibiotic resistance, and financial costs of prolonged postoperative antibiotic prophylaxis.

Background and objectives AKI is classified as prerenal, intrinsic, and postrenal. Prerenal AKI and intrinsic AKI represent the most common causes for AKI in hospitalized patients. This study aimed to examine the accuracy of the fractional excretion of sodium for distinguishing intrinsic from prerenal AKI. Design, setting, participants, & measurements We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, the Cochrane Library, and Scopus for all available studies that met the criteria until December 31, 2021. We included studies that evaluated fractional excretion of sodium in differentiating AKI etiologies in adults, whereas studies that did not have sufficient data to extract a 2×2 table were excluded. We assessed the methodologic quality using the Quality Assessment of Diagnostic Accuracy Studies-2 tool and extracted the diagnostic accuracy data for all included studies. We conducted a meta-analysis using the bivariate random effects model. We performed subgroup analysis to investigate sources of heterogeneity and the effect of the relevant confounders on fractional excretion of sodium accuracy. Results We included 19 studies with 1287 patients. In a subset of 15 studies (872 patients) that used a threshold of 1%, the pooled sensitivity and specificity for differentiating intrinsic from prerenal AKI were 90% (95% confidence interval, 81% to 95%) and 82% (95% confidence interval, 70% to 90%), respectively. In a subgroup of six studies (511 patients) that included CKD or patients on diuretics, the pooled sensitivity and specificity were 83% (95% confidence interval, 64% to 93%) and 66% (95% confidence interval, 51% to 78%), respectively. In five studies with 238 patients on diuretics, the pooled sensitivity and specificity were 80% (95% confidence interval, 69% to 87%) and 54% (95% confidence interval, 31% to 75%), respectively. In eight studies with 264 oliguric patients with no history of CKD or diuretic therapy, the pooled sensitivity and specificity were 95% (95% confidence interval, 82% to 99%) and 91% (95% confidence interval, 83% to 95%), respectively. Conclusions Fractional excretion of sodium has a limited role for AKI differentiation in patients with a history of CKD or those on diuretic therapy. It is most valuable when oliguria is present.

Abstract There is great interest in expanding the use of ultrasound (US), but new challenges exist with its application to lumbar facet–targeted procedures. The primary aim of this systematic review and meta-analysis was to determine the risk of incorrect needle placement associated with US–guided lumbar medial branch blocks (MBB) and facet joint injections (FJI) as confirmed by fluoroscopy or computerized tomography (CT). An a priori protocol was registered, and a database search was conducted. Inclusion criteria included all study types. Risk of bias was assessed using the Cochrane risk of bias tool for randomized controlled trials and the National Heart, Lung, and Blood tool for assessing risk bias for observational cohort studies. Pooled analysis of the risk difference (RD) of incorrect needle placement was calculated. Pooled analysis of 7 studies demonstrated an 11% RD (P < 0.0009) of incorrect needle placement for US-guided MBB confirmed using fluoroscopy with and without contrast. Pooled analysis of 3 studies demonstrated a 13% RD (P < 0.0001) of incorrect needle placement for US-guided FJI confirmed using CT. The time to complete a single-level MBB ranged from 2.6 to 5.0 minutes. The certainty of evidence was low to very low. Ultrasound-guided lumbar MBB and FJI are associated with a significant risk of incorrect needle placement when confirmed by fluoroscopy or CT. The technical limitations of US and individual patient factors could contribute to the risk of incorrect needle placement.

Abstract Objectives To systematically review the psychometric properties of outcome measurement instruments used in ANCA-associated vasculitis (AAV). Methods Medline, EMBASE, Cochrane, Scopus and Web of Science were searched from inception to 14 July 2020 for validation studies of instruments used in AAV. Following the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) and OMERACT frameworks, different psychometric properties (validity, reliability, responsiveness and feasibility) were summarized. Risk of bias was assessed according to the COSMIN checklist. Results From 2505 articles identified, 32 met the predefined selection criteria, providing information on 22 instruments assessing disease activity (n = 7), damage (n = 2), activity and damage (n = 1), health-related quality of life (HRQoL; n = 9) and function (n = 3). Most of the instruments were tested in AAV as a group or in granulomatosis with polyangiitis only. The BVAS, any version, the Vasculitis Damage Index (VDI) and the AAV-Patient-Reported Outcome (AAV-PRO) have been more extensively validated than the other instruments. BVAS for Wegener Granulomatosis (BVAS/WG) has been shown to be valid for measuring disease activity [correlation with Physician global assessment (r = 0.90)], reliability (inter-observer intraclass correlation coefficient = 0.97), responsiveness and feasibility. For damage, VDI was shown to be moderately valid (correlations with BVAS version 3 at 6 months r = 0.14, BVAS/WG at 1 year r = 0.40 and 5 years r = 0.20), and feasible. For HRQoL, AAV-PRO demonstrated validity (correlations of the six AAV-PRO domains with EQ-5D-5L: −0.78 to −0.55; discrimination between active disease and remission, P &lt; 0.0001 for all comparisons). The overall performance of instruments assessing function was low-to-moderate. Conclusion Among the 22 outcome measurement instruments used for AAV, BVAS (any version), VDI and AAV-PRO had the strongest psychometric properties.

Abstract Cycle threshold (CT) values are correlated with the amount of viral nucleic acid in a sample and may be obtained from some qualitative real-time polymerase chain reaction tests used for diagnosis of most patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, CT values cannot be directly compared across assays, and they must be interpreted with caution as they are influenced by sample type, timing of sample collection, and assay design. Presently, the correlation between CT values and clinical outcomes is not well understood. We conducted a systematic review and meta-analysis of published studies through April 19, 2021, that reported an association between CT values and hospitalization, disease severity, and mortality in patients ≥18 years old with SARS-CoV-2. A meta-analysis of 7 studies showed no significant difference in mean CT values between hospitalized and nonhospitalized patients. Among hospitalized patients, those with CT values &lt;25 had a high risk of more severe disease and mortality than patients with CT values &gt;30 (odds ratio [OR], 2.31; 95% CI, 1.70 to 3.13; and OR, 2.95; 95% CI, 2.19 to 3.96; respectively). The odds of increased disease severity and mortality were less pronounced in patients with CT values of 25–30 compared with &gt;30.

AbstractObjectiveThis systematic review updates the evidence for association between oral health characteristics and frailty status, identifying gaps in translational dental research and application of frailty assessment into clinical practice.BackgroundClinicians have little guidance on stage‐appropriate dental treatment for medically complex older adults. Oral health characteristics have been associated with frailty status, determined through validated assessment tools representing a concise measure of health. Translation of frailty assessment into dental practice has not been the focus of previous reviews.MethodsUtilising the PRISMA framework for systematic reviews, a comprehensive database search identified articles describing the association of interest. Those included were cross‐sectional or longitudinal, in English, included participants aged 50 years or older, used validated frailty assessments and measured clinically relevant oral health outcomes. From 835 screened articles, 26 full‐text articles were eligible for quality appraisal and synthesis.ResultsFrailty prevalence ranged from 8.5% to 66.0%. Most studies utilised the Fried frailty criteria. Qualitative synthesis of 17 cross‐sectional and nine longitudinal studies demonstrated significant covariate‐adjusted association between frailty status and number of teeth, chewing ability, prosthetic characteristics, dental caries, periodontitis, dental utilisation and oral health‐related quality of life factors. Variability in findings reflected study sample diversity based on country of study origin, age at recruitment, sample size, frailty assessment type, use of clinical versus self‐reported outcome measures and differences in statistical analysis.ConclusionDespite robust evidence of association with oral health characteristics, frailty assessment has yet to be sufficiently applied to translational dental research and clinical practice.

SummaryBackgroundNeoplasia detection rate, the proportion of Barrett's oesophagus patients with high‐grade dysplasia or oesophageal adenocarcinoma detected at index surveillance endoscopy has been proposed as a quality metric. However, the correlation between neoplasia detection rate and a clinically relevant outcome like post‐endoscopy Barrett's neoplasia remains unknown. Post‐endoscopy Barrett's neoplasia refers to the rate of high‐grade dysplasia or oesophageal adenocarcinoma on repeat endoscopy within one year of an index screening examination revealing non‐dysplastic Barrett's oesophagus or low‐grade dysplasia.AimTo assess correlation between neoplasia detection rate and post‐endoscopy Barrett's neoplasia.MethodsWe performed a systematic search of multiple databases from date of inception to June 2021 to identify cohort studies reporting both neoplasia detection rate and post‐endoscopy Barrett's neoplasia. Data from each study were pooled using a random effects model, and their correlation assessed using meta‐regression. Heterogeneity was assessed and a priori planned subgroup analyses were conducted.ResultsTen studies with 27 894 patients with Barrett's oesophagus were included. The pooled neoplasia detection rate and post‐endoscopy Barrett's neoplasia were 5.0% (95% CI: 3.4%‐7.1%, I2 = 97%) and 19.6% (95% CI: 10.1%‐34.7%, I2 = 96%), respectively. Meta‐regression revealed a statistically significant inverse relationship between the two variables (coefficient −3.50, 95% CI: −4.63 to −2.37, P < 0.01). With every 1% increase of neoplasia detection rate, post‐endoscopy Barrett's neoplasia decreased by 3.50%. Heterogeneity was high despite adjusting for study quality and performing several subgroup analyses.ConclusionWe observed a statistically significant inverse correlation between neoplasia detection rate and post‐endoscopy Barrett's neoplasia. Additional studies are needed to further validate this correlation.
