Asymptomatic Intracerebral Hemorrhage Following Endovascular Stroke Therapy Is Not Benign: A Systematic Review and Meta-Analysis.

BACKGROUND: Asymptomatic intracerebral hemorrhage (aICH) occurs in approximately 35% of patients with acute ischemic stroke after endovascular thrombectomy. Unlike symptomatic ICH, studies evaluating the effect of aICH on outcomes have been inconclusive. We performed a systematic review and meta-analysis to evaluate the long-term effects of postendovascular thrombectomy aICH. METHODS AND RESULTS: The meta-analysis protocol was submitted to the International Prospective Register of Systematic Reviews a priori. PubMed, Scopus, and Web of Science were searched from inception through September 2023, yielding 312 studies. Two authors independently reviewed all abstracts. Included studies contained adult patients with ischemic stroke undergoing endovascular thrombectomy with follow-up imaging assessment of ICH reporting comparative outcomes according to aICH versus no ICH. After screening, 60 papers were fully reviewed, and 10 studies fulfilled inclusion criteria (n=5723 patients total, 1932 with aICH). Meta-analysis was performed using Cochrane RevMan v5.4. Effects were estimated by a random-effects model to estimate summary odds ratio (OR) of the effect of aICH versus no ICH on primary outcomes of 90-day modified Rankin Scale 3 to 6 and mortality. The presence of aICH was associated with a higher odds of 90-day mRS 3 to 6 (OR, 2.17 [95% CI, 1.81-2.60], P<0.0001, I2 46% Q 19.15) and mortality (OR, 1.72 [95% CI, 1.17-2.53], P:0.005, I2 79% Q 27.59) compared with no ICH. This difference was maintained following subgroup analysis according to hemorrhage classification and recanalization status. CONCLUSIONS: The presence of aICH is associated with worse 90-day functional outcomes and higher mortality. Further studies to evaluate the factors predicting aICH and treatments aimed at reducing its occurrence are warranted.

Variability in Minimal Clinically Important Difference Calculation and Reporting in the Otolaryngology Literature.

OBJECTIVE: Best practices for calculation of the minimal clinically important difference (MCID) of outcome measures include the use of complementary methodologies (broadly classified as anchor-based and distribution-based) and reporting of the MCID's predictive ability. We sought to determine MCID calculation and reporting patterns within the otolaryngology literature. METHODS: A systematic search strategy of Embase, PubMed, and Web of Science databases was developed and implemented to identify studies reporting the determination of an MCID for an outcome measure. Studies specifically within the otolaryngology literature (defined as journals classified as "otorhinolaryngology" in the Journal Citation Reports database) were included. All those journals were additionally searched for relevant articles. RESULTS: There were 35 articles that met the inclusion criteria. Of these studies, 88.6% reported MCID of a patient-reported outcome measure and the remainder were for objective outcome measurements. Anchor-based methods were used by 82.9% of studies and distribution-based methods were used by 68.6% of studies. Of all studies, 31.4% utilized anchor-based methods alone, 17.1% utilized distribution-based methods alone, and 51.4% used both methods. Only 25.7% of studies reported the sensitivity (median: 60.8%, range: 40.5%-86.7%) and specificity (median: 80.4%, range: 63.5%-88.0%) of the MCID to detect patients experiencing clinically important change. CONCLUSION: Deviation from best practices in MCID calculation and reporting exists within the otolaryngology literature, with almost half of all studies only using one method of MCID calculation and almost three-quarters not reporting the predictive ability (sensitivity/specificity) of the calculated MCID. When predictive ability is reported, however, MCIDs appear to be more specific than sensitive. LEVEL OF EVIDENCE: NA Laryngoscope, 134:2059-2069, 2024.

Examining the Role of Women, Infant, and Children in Black Women Breastfeeding Duration and Exclusivity: A Systematic Review.

Background: African American women continue to experience low rates of breastfeeding initiation as well as low rates of exclusive breastfeeding for 6 months. Research has indicated that there are several social determinants that impact breastfeeding rates, but there is a dearth of literature that allows African American women to give voice to their experiences. In addition, research has shown women, infant, and children (WIC) participants to have lower breastfeeding rates than non-WIC eligible women. Research Aim/Question: The aim of this systematic review was to examine the relationship between WIC program participation and breastfeeding initiation and duration among non-Hispanic African American/Black women. Methods: The approach for this review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Four online databases, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, MEDLINE, and SCOPUS, were used to search for peer-reviewed articles and grey literature. Results: Two hundred eighteen articles were retrieved through the database search and underwent initial screening, yielding 59 potential eligible articles. Full-text articles were further reviewed and 11 met the inclusion criteria and were included in this systematic review. Conclusions: Included studies show mixed results regarding the association between WIC participation and breastfeeding initiation, but there is a general negative association between WIC participation and breastfeeding duration, especially among Black women.

Heterogeneity in the definition of chronic rhinosinusitis disease control: a systematic review of the scientific literature.

PURPOSE: Disease control is conceptually recognized to be an important outcome measure for chronic rhinosinusitis (CRS). However, inconsistent usage is a significant factor in disadoption of important concepts and it is presently unclear how consistently the construct of CRS 'control' is being defined/applied. The objective of this study was to determine the heterogeneity of CRS disease control definitions in the scientific literature. METHODS: Systematic review of PubMed and Web of Science databases from inception through December 31, 2022. Included studies used CRS disease control as an explicitly stated outcome measure. The definitions of CRS disease control were collected. RESULTS: Thirty-one studies were identified with more than half published in 2021 or later. Definitions of CRS control were variable, although 48.4% of studies used the EPOS (2012 or 2020) criteria to define control, 14 other unique definitions of CRS disease control were also implemented. Most studies included the burden CRS symptoms (80.6%), need for antibiotics or systemic corticosteroids (77.4%) or nasal endoscopy findings (61.3%) as criteria in their definitions of CRS disease control. However, the specific combination of these criteria and prior time periods over which they were assessed were highly variable. CONCLUSION: CRS disease control is not consistently defined in the scientific literature. Although many studies conceptually treated 'control' as the goal of CRS treatment, 15 different criteria were used to define CRS disease control, representing significant heterogeneity. Scientific derivation of criteria and collaborative consensus building are needed for the development of a widely-accepted and -applied definition of CRS disease control.

Minimal Radiographic Mucosal Thickness or Opacification Criterion for Sinus-Specific Endoscopic Sinus Surgery for Chronic Rhinosinusitis.

OBJECTIVE: Primary chronic rhinosinusitis (CRS) is typically a diffuse process and the extent of endoscopic sinus surgery (ESS) performed for medically recalcitrant CRS is impacted by many factors. However, some third-party payors have implemented policies to authorize coverage for ESS in a sinus-by-sinus manner based on a minimal measurement of millimeters of mucosal thickening or sinus opacification in the corresponding sinus that is being surgically addressed. Our objective was to determine whether such policies are based on scientific evidence that in patients with medically recalcitrant CRS, a minimum measurement of mucosal thickening or sinus opacification is a predictor of CRS in that sinus or improved outcomes after ESS on a sinus-by-sinus basis. DATA SOURCES: Medline, Embase, Scopus, and Web of Science databases, from inception through May 2022. REVIEW METHODS: A systematic review was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. RESULTS: We identified 6070 abstracts which were screened and from which 112 studies ultimately underwent a full-text review. From these studies, we found that none investigated (or provided evidence of) whether any minimal degree of radiographic mucosal thickening or sinus opacification predicted CRS or better outcomes after ESS in a sinus-specific manner. CONCLUSION: We were unable to find evidence supporting a minimum millimeter measurement of mucosal thickening or sinus opacification as predictors of CRS or better post-ESS outcomes in a sinus-specific manner in patients with medically recalcitrant CRS. The extent of ESS for CRS should be determined through personalized medical decision-making that considers all patient-specific factors.

Early (<4 weeks) versus standard (≥4 weeks) endoscopic drainage of pancreatic walled-off fluid collections: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Previous studies have demonstrated that the ideal time for drainage of walled-off pancreatic fluid collections is 4 to 6 weeks after their development. However, some pancreatic collections, notably infected pancreatic fluid collections, require earlier drainage. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. The aim of this study was to evaluate the clinical efficacy and safety of EUS-guided drainage of pancreatic fluid collections <4 weeks after development compared with ≥4 weeks after development. METHODS: Search strategies were developed for PubMed, Embase, and Cochrane Library databases from inception. Outcomes of interest were technical success, defined as successful endoscopic placement of a lumen-apposing metal stent; clinical success, defined as a reduction in cystic collection size; and procedure-related adverse events. A random-effects model was used for analysis, and results are expressed as odds ratio (OR) with 95% confidence interval (CI). RESULTS: Six studies (630 patients) were included in our final analysis, in which 182 patients (28.9%) were enrolled in the early drainage cohort and 448 patients (71.1%) in the standard drainage cohort. The mean fluid collection size was 143.4 ± 18.8 mm for the early cohort versus 128 ± 19.7 mm for the standard cohort. Overall, technical success was equal in both cohorts. Clinical success did not favor either standard drainage or early drainage (OR, .39; 95% CI, .13-1.22; P = .11). No statistically significant differences were found in overall adverse events (OR, 1.67; 95% CI, .63-4.45; P = .31) or mortality (OR, 1.14; 95% CI, .29-4.48; P = .85). Hospital stay was longer for patients undergoing early drainage compared with standard drainage (23.7 vs 16.0 days, respectively). CONCLUSIONS: Both early (<4 weeks) and standard (≥4 weeks) drainage of walled-off pancreatic fluid collections offer similar technical and clinical outcomes. Patients requiring endoscopic drainage should not be delayed for 4 weeks.

Cold Endoscopic Mucosal Resection (c-EMR) of Nonpedunculated Colorectal Polyps ≥20 mm: A Systematic Review and Meta-analysis.

BACKGROUND: There is increasing evidence that cold endoscopic mucosal resection (c-EMR) can effectively treat large colorectal polyps. We aim to appraise the current literature and evaluate outcomes following c-EMR for nonpedunculated colonic polyps ≥20 mm. METHODS: Major databases were searched. Primary outcomes included recurrence rate and adverse events. Meta-analysis was performed using a random-effects model. RESULTS: Nine articles were included in the final analysis, which included 817 patients and 1077 colorectal polyps. Average polyp size was 28.8 (±5.1) mm. The pooled recurrence rate of polyps of any histology at 4 to 6 months was 21.0% (95% CI: 9.0%-32.0%, P<0.001, I2=97.3, P<0.001). Subgroup analysis showed that recurrence was 10% for proximal lesions (95% CI: 0.0%-20.0%, P=0.054, I2=93.7%, P=0.054) and 9% for distal lesions (95% CI: 2.0%-21.0%, P=0.114, I2=95.8%, P=0.114). Furthermore, subgroup analysis showed that recurrence was 12% for adenoma (95% CI: 4.0%-19.0%, P=0.003, I2=98.0%, P=0.003), and 3% for sessile serrated polyps (95% CI: 1.0%-5.0%, P=0.002, I2=34.4%, P=0.002). Post-polypectomy bleeding occurred in 1% (n=8/817) of patients, whereas abdominal pain occurred in 0.2% (n=2/817) of patients. CONCLUSIONS: C-EMR for nonpedunculated colorectal polyps ≥20 mm shows an excellent safety profile with a very low rate of delayed bleeding as well as significantly less recurrence for sessile serrated polyps than adenomas.

A systematic review of adherence to anticoagulation regimens in pediatric patients.

Thromboembolic disease rates are increasing in pediatric patients. Anticoagulation is prescribed for treatment and prevention of thromboembolic disease. While nonadherence to anticoagulation regimens predicts poor health outcomes in adults, data in anticoagulated pediatric patients are limited. We systematically reviewed the rates, outcomes, and predictors of anticoagulation nonadherence in the pediatric population. Out of a total of 3581 unique articles identified for review, 17 studies met inclusion criteria. These studies primarily evaluated patients with cardiac disease treated with vitamin K antagonists. Overall nonadherence rates varied from 3% to 42%, based upon population, definition of adherence, and measurement strategy. Patient age, goal international normalized ratio (INR), and number of concurrent potentially interacting medications correlated with nonadherence. Data examining the relationship between nonadherence and health outcomes were included in only two studies. Limitations of current literature, as well as critical knowledge gaps that require future study, are discussed.

Chimeric antigen receptor T-cell therapy in adults with B-cell acute lymphoblastic leukemia.

Chimeric antigen receptor T-cell (CAR-T) therapy has transformed treatment paradigms for relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (B-ALL) in children and younger adults. We performed a systematic review to investigate the published literature on efficacy and toxicity of CAR-T therapy in adults with r/r B-ALL. We searched MEDLINE, Embase, and the Cochrane Library for prospective interventional studies and included published studies of ≥5 patients with median age at enrollment of ≥18 years. Risk of bias was assessed with a modified Institute of Health Economics tool. A total of 2566 records were assessed; 16 studies involving 489 patients were included in the final analysis. The mean complete remission (CR) rate was 81% and the measurable residual disease (MRD)-negative remission rate was 81% at 4 weeks after CAR-T infusion. With median follow-up across studies of 24 months, the cumulative 12-month probabilities of progression-free survival (PFS) and overall survival (OS) were 37% (95% CI, 26-48) and 57% (95% CI, 49-65), respectively. Relapse occurred in 40.3% of cases; target antigen was retained in 73.2% of relapses. Across studies, any grade of cytokine release syndrome (CRS) occurred in 82% of patients (95% CI, 61-95) and grade 3 or higher CRS in 27% (95% CI, 18-36). Neurotoxicity of any grade occurred in 34% of patients (95% CI, 24-47) and grade 3 or higher in 14% (95% CI, 1-25). In summary, CAR-T therapy achieves high early remission rates in adults with r/r B-ALL and represents a significant improvement over traditional salvage chemotherapy. Relapses are common and durable response remains a challenge.
