Review
PURPOSE
Functional endoscopic sinus surgery (FESS) is a mainstay surgical intervention for chronic rhinosinusitis with nasal polyposis (CRSwNP). Nasal irrigation, particularly with normal saline, is a widely recommended postoperative care modality. This systematic review and meta-analysis aimed to assess the efficacy of various nasal irrigation solutions in postoperative FESS patients.
METHODS
A comprehensive search was conducted in multiple databases for randomized controlled trials investigating normal saline and various substances for nasal irrigation post-FESS. The systematic review followed PRISMA guidelines, and the meta-analysis used R software for data synthesis. Outcome measures included SNOT-22 and LKES scores. The Cochrane tool was employed to evaluate the potential for bias.
RESULTS
Results from 14 studies, focusing on six each for SNOT-22 and LKES, revealed a significant reduction in symptoms and endoscopic scores with various solutions compared to normal saline. The meta-analysis using the random-effects model indicated a negative standardized mean difference (SMD) of - 0.69(95% CI [- 1.64; 0.27], p = 0.157) for symptoms and endoscopic scores (SMD = - 0.48, 95% CI [- 1.32; 0.36], z = - 1.12, p = 0.264). Subgroup analyses highlighted budesonide's efficacy over normal saline, but substantial heterogeneity and potential publication bias were noted.
CONCLUSION
Nasal irrigation with various solutions postoperative FESS patients demonstrated significant improvements in patient-reported symptoms and endoscopic scores compared to normal saline. Budesonide appeared particularly effective. However, high heterogeneity and potential publication bias warrant cautious interpretation. Standardized outcome measures and further research are needed to strengthen the evidence.

Review
OBJECTIVE
Provide clinicians with current evidence for biologic therapy in children with chronic rhinosinusitis with nasal polyposis (CRSwNP).
DATA SOURCES
PubMed, MEDLINE, Cochrane, and clinical trial registries.
REVIEW METHODS
Key search terms related to biologic therapy in pediatric CRSwNP were identified via a structured query of current medical literature and clinical trial databases.
CONCLUSIONS
There is a dearth of active clinical trials and research studies for biologics targeting pediatric CRSwNP. There is an ongoing compassionate-use clinical trial involving Dupilumab for children with nasal polyps as well as only 1 published work specifically focused on Dupilumab for pediatric CRSwNP in the setting of aspirin-exacerbated respiratory disease.
IMPLICATIONS FOR PRACTICE
For children with atopic dermatitis, asthma, and chronic idiopathic urticaria, biologic therapies such as Omalizumab, Dupilumab, and Mepolizumab have gained Food and Drug Administration approval. The role of biologic therapy in pediatric CRSwNP demonstrates significant promise in the comprehensive management of the unified airway. Additional Phase III trials are necessary to broaden clinical indications for children with comorbid conditions and complex sinonasal disease.

BACKGROUND
Restorative proctocolectomy and IPAA have become the surgical procedure of choice in pediatric patients with medically refractory colitis or familial adenomatous polyposis.
OBJECTIVE
This systematic review aims to assess the diagnosis and treatment of pouch disorders in pediatric patients who undergo IPAA.
DATA SOURCES
A literature search was performed using MEDLINE, Google Scholar, and Embase for all publications describing outcomes of pediatric IPAA.
STUDY SELECTION
Studies between January 1, 2000, and September 7, 2022, published in English were included. Studies were excluded on the basis of title, abstract, and full-length review.
INTERVENTIONS
IPAA.
MAIN OUTCOME MEASURES
Pouch disorders described include anastomotic leaks, pouch strictures, pouch failure, pouchitis, cuffitis, and de novo Crohn's disease of the pouch.
RESULTS
Thirty-three studies were included in this review, all of which were retrospective in nature. The outcomes of 2643 pediatric patients were included in the 33 studies.
LIMITATIONS
Management is largely informed by clinical practices in adult patients with scant data on treatment efficacy in children.
CONCLUSIONS
The reported incidence of disorders of the pouch in children varies widely and is likely attributable to differences in definitions and follow-up periods across studies. Pouchitis was the most frequently described outcome. The overall rate of pouch failure in children is relatively low, with de novo Crohn's disease of the pouch being the most significant risk factor. Multicenter prospective studies are needed in the pediatric population to accurately identify risk factors, standardize the assessment of pouch complications, and determine effective treatment strategies.

Stapled Anastomosis Versus Hand-Sewn Anastomosis With Mucosectomy for Ileal Pouch-Anal Anastomosis: A Systematic Review and Meta-analysis of Postoperative Outcomes, Functional Outcomes, and Oncological Safety.
PURPOSE
This systematic review and meta-analysis aimed to compare outcomes between stapled ileal pouch-anal anastomosis (IPAA) and hand-sewn IPAA with mucosectomy in cases of ulcerative colitis and familial adenomatous polyposis.
METHODS
This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis) guidelines 2020 and AMSTAR 2 (Assessing the methodological quality of systematic reviews) guidelines. We included randomized clinical trials (RCTs) and controlled clinical trials (CCTs). Subgroup analysis was performed according to the indication for surgery.
RESULTS
The bibliographic research yielded 31 trials: 3 RCTs, 5 prospective clinical trials, and 24 CCTs including 8872 patients: 4871 patients in the stapled group and 4038 in the hand-sewn group. Regarding postoperative outcomes, the stapled group had a lower rate of anastomotic stricture, small bowel obstruction, and ileal pouch failure. There were no differences between the 2 groups in terms of operative time, anastomotic leak, pelvic sepsis, pouchitis, or hospital stay. For functional outcomes, the stapled group was associated with greater outcomes in terms of seepage per day and by night, pad use, night incontinence, resting pressure, and squeeze pressure. There were no differences in stool Frequency per 24h, stool frequency at night, antidiarrheal medication, sexual impotence, or length of the high-pressure zone. There was no difference between the 2 groups in terms of dysplasia and neoplasia.
CONCLUSIONS
Compared to hand-sewn anastomosis, stapled ileoanal anastomosis leads to a large reduction in anastomotic stricture, small bowel obstruction, ileal pouch failure, seepage by day and night, pad use, and night incontinence. This may ensure a higher resting pressure and squeeze pressure in manometry evaluation.

Meta-Analysis
INTRODUCTION
Individuals with familial adenomatous polyposis (FAP) have an almost 20% lifetime risk of duodenal adenocarcinoma, currently the leading cause of death in FAP. The Spigelman staging system provides guidance on the surveillance intervals and timing of prophylactic surgery. Still, its accuracy in predicting duodenal and papillary cancer development has not been systematically evaluated. We investigated the sensitivity and cancer risk of the Spigelman stages.
METHODS
We performed a systematic review on PubMed, MEDLINE, EMBASE, and Cochrane and used a random-effects model to pool effect sizes.
RESULTS
After removing duplicate entries, we screened 1,170 records and included 27 studies for quantitative analysis. Once duodenal polyposis reaches Spigelman stage IV, the risk of duodenal and papillary cancers increased to 25% (95% confidence interval [CI] 12%-45%). However, the sensitivity of Spigelman stage IV for these cancers was low (51%, 95% CI 42%-60%), especially for papillary adenocarcinoma (39%, 95% CI 16%-68%). We investigated the reasons behind these low values and observed that duodenal cancer risk factors included polyps >10 mm, polyp count >20, and polyps with high-grade dysplasia. Risk factors associated with papillary cancer included a papilla with high-grade dysplasia or >10 mm. The evidence on other risk factors was inconclusive.
DISCUSSION
The current Spigelman staging system had a low sensitivity for duodenal and papillary adenocarcinomas. Two Spigelman variables (duodenal villous histology and polyp count) and the lack of papilla-specific variables likely contributed to the low sensitivity values for duodenal and papillary cancers, respectively. While clinicians may be familiar with its current form, there is an urgent need to update it.

Meta-Analysis Review
OBJECTIVE
The aim of this Meta-analysis and systematic review was to perform a comprehensive assessment of the association of chronic rhinosinusitis (CRS) with overweight/obesity, leptin hormone, and its associated metabolic dysregulation.
DATA SOURCES
Ovid MEDLINE, Embase, Web of Science, and Cochrane Central Register of Controlled Trials, were searched for studies from 1946 to October 2022, using predefined syntax.
REVIEW METHODS
Outcome data for the meta-analysis were extracted on odds ratios (OR) of CRS prevalence based on the presence of overweight/obesity and mean serum leptin levels. A Meta-analysis was performed using the DerSimonian-Laird estimator to pool extracted data by the generalized inverse variance approach. Random effect models were utilized due to the small sample size. A qualitative synthesis was performed on articles that did not meet the inclusion criteria for the Meta-analysis.
RESULTS
Thirty-six studies met the systematic review inclusion criteria out of 1113 articles screened. A total of 6 studies were included in the pooled Meta-analysis of the various outcome variables. Our pooled meta-analysis observed a positive association between overweight/obesity and the prevalence of CRS (OR = 1.33, 95% confidence interval [CI]: 1.17-1.51). The pooled ratio of the means analysis of the mean serum leptin levels between CRS with nasal polyposis and control patients was 2.21 (95% CI: 1.45; 3.36).
CONCLUSION
Our pooled Meta-analysis indicates a positive association between overweight/obesity and CRS. Future prospective studies are needed to explore the association between CRS and obesity with an understanding of potential confounding comorbidities, including studies focused on assessing the underlying immunologic mechanism of this association.

Review
BACKGROUND
Cystic fibrosis (CF) is a life-shortening, autosomal recessive disease that leads to abnormal electrolyte concentration in exocrine secretions. Secretion stasis in paranasal sinuses determines chronic rhinosinusitis (CRS) and nasal polyposis. Endoscopic sinus surgery is used to open the sinuses and allow medical treatment to work properly.
OBJECTIVES
To determine the effects of sinus surgery alone or in combination with medical treatment (non-surgical) compared to medical treatment (non-surgical) alone on both nasal and pulmonary function in people with CF diagnosed with CRS with nasal polyposis. Further, to evaluate the impact of sinus surgery (with or without medical treatment) on hospitalization rates, use of antibiotics and pulmonary exacerbation rates.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and hand searching of journals and conference abstract books. Date of last search: 4 July 2022. We also searched other databases (Pubmed, Embase, World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Virtual Health Library and ClinicalTrials.gov). Date of last search: 18 September 2022.
SELECTION CRITERIA
Randomized controlled trials (RCTs) comparing groups who underwent endoscopic sinus surgery and groups with medical treatment alone.
DATA COLLECTION AND ANALYSIS
The review authors independently selected studies, extracted data, assessed the risk of bias and evaluated the certainty of the evidence using GRADE. They contacted the authors of the included study for additional information.
MAIN RESULTS
We identified 66 publications relating to 50 studies from electronic searches. Only one study fulfilled the inclusion criteria, and only limited information was available. In this study, 28 participants aged 19 to 28 years were randomized in equal numbers to either nasal irrigation alone or nasal irrigation with surgery (endoscopic polypectomy with extended sinusotomy). The certainty of the evidence was very low according to the GRADE approach. We are uncertain whether, compared to medical treatment alone, the addition of surgical intervention improves nasal symptoms, or reduces bacterial colonization, the use of antibiotics and pulmonary exacerbations. We are also uncertain whether the addition of surgery to medical treatment leads to changes in pulmonary function. There was one episode of bleeding during surgery that was corrected during the procedure with no further consequences. The study did not report on survival.
AUTHORS' CONCLUSIONS
Very low-certainty evidence means we are not certain if endoscopic sinus surgery to treat chronic rhinosinusitis with nasal polyposis in cystic fibrosis is effective. Future research should be multicentric to increase the number of participants and increase statistical power. Adequate randomization and allocation concealment are important to guarantee that the groups are similar. Blinding, however, may not be possible in an ethical trial; even without blinding, results can achieve high-level evidence if the outcomes used are objective parameters. Future research should follow participants of all ages for at least 12 months to evaluate the evolution of nasal polyposis, its recurrence and how symptoms may return. We also consider mortality an important outcome to be assessed. Future clinical research should consider the effects of cystic fibrosis transmembrane conductance regulators, a new group of drugs that may affect the development of nasal polyps.

Frontiers in Oncology 2023To evaluate the efficacy of Difluoromethylornithine (DFMO) chemoprevention in the high-risk population for colorectal cancer (CRC).
OBJECTIVES
To evaluate the efficacy of Difluoromethylornithine (DFMO) chemoprevention in the high-risk population for colorectal cancer (CRC).
METHODS
Meta-analysis was conducted to assess the caliber of the included literature by searching five databases for randomized controlled trials of DFMO chemoprevention in the high-risk population of CRC, with RevMan 5.4, Stata 15.0 and TSA 0.9.5.10 employed to statistically analyze the extracted data. Grade profiler 3.6 was employed for grading the evidence for the outcome indicators (disease progression and adenoma incidence).
RESULTS
Six trials were finally included in this research, with the collective data indicating that the DFMO combination therapy was efficacious in lowering the incidence of recurrent adenomas in patients who had experienced advanced CRC [RR 0.34, 95% CI 0.14 - 0.83, P < 0.05]. Meta-analysis showed that DFMO combined therapy had no statistical difference in disease progression in patients with familial adenomatous polyposis[RR 0.52, 95% CI 0.14 - 1.86, P > 0.05]; Trial Sequential Analysis reveals that the combination therapy of DFMO effectively diminishes the occurrence of recurrent adenomas in patients with a history of advanced colorectal tumors, displaying a Risk Ratio (RR) of 0.33 with a 95% Confidence Interval (CI) of 0.12 - 0.90 and a significance level of P < 0.05. This combination exhibits a statistically significant difference. Subgroup analysis demonstrates that, depending on the drug treatment regimen (DFMO+ Aspirin/DFMO+ Sulindac), the combination of DFMO and aspirin exhibits an effect comparable to a placebo in diminishing the occurrence of new adenomas in patients with a history of advanced colorectal tumors. However, the combination of DFMO and sulindac significantly mitigates the incidence of recurrent adenomas in this patient population.
CONCLUSION
This meta-analysis indicates that the existing randomized controlled trials are adequate to ascertain the efficacy of DFMO combination therapy in diminishing the incidence of recurrent adenomas in patients who have previously encountered advanced colorectal tumors. However, further clinical trials need to be conducted to evaluate the optimum dosage and treatment course of prophylactic implementation of DFMO combination therapy in high-risk populations.

Review
Chronic rhinosinusitis (CRS) is a large group of heterogeneous diseases characterized by extensive inflammation of the nasal mucosa and sinuses. Vitamin D (VD), as an immunoregulatory hormone, may play an important role in the pathophysiology of CRS. The purpose of this study is to review the existing literature that correlates VD levels with CRS with or without nasal polyps. A systematic manual search was conducted in the PubMed and Google Scholar databases up to July 2023. Articles from PubMed and the first 100 articles from Google Scholar were recorded for our research. Keywords used were the following: vitamin D, chronic rhinosinusitis, and nasal polyps. Among the 134 articles retrieved, only 18 were eligible. The other 116 studies were excluded as they related VD levels with other conditions (e.g., allergic rhinitis) and for other reasons. However, we identified two more eligible records through the manual research of the above-mentioned 132 studies, and finally, 20 records were included in the current review. The review concerned case-control studies, prospective, retrospective, and cross-sectional studies. Based on our review, we concluded that CRS patients are correlated with the lowest VD levels, accompanied by increased severity of the disease, especially in those with nasal polyposis. Patients can benefit from appropriate VD supplementation, and serum VD levels should be included in the laboratory assessment of CRS. However, due to the heterogeneity of the individuals involved, more well-designed clinical trials as well as randomized clinical trials should be conducted for further validation of the above findings in the general population in the future.

BACKGROUND
The role of periostin in the pathophysiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) has been debated in the literature, with several authors proposing periostin as a potential biomarker or theurapeutical target. However, the mechanisms regulating the systematic or local periostin production in both CRSwNP patients and controls remain elusive.
METHODOLOGY
Any factors reported to affect periostin expression in polyp tissue samples, nasal mucosa samples, serum and nasal secretions were considered as primary outcomes in this systematic review. Interactions or synergistic effects between bias factors were considered as secondary outcomes.
RESULTS
Eosinophilic CRSwNP, large polyp size and radiological severity were found to be high-risk, positive bias factors for periostin levels in polyp tissue samples, while the role of atopy and asthma has been debated. Immunotherapy and eosinophilic endotype were identified as biases for serum periostin measurements, while steroids and non-steroidal anti-inflammatory drug exacerbated respiratory disease remain of unclear risk. Bronchal asthma, eosinophilic endotype and immunotherapy have been reported to bias periostin measurements in nasal secretions.
CONCLUSIONS
The relevant literature is extremely limited and little is actually known about the intrinsic or extrinsic factors affecting periostin measurements. The synthesis of the existing literature should be done with cautiousness.
