Meta-Analysis Review
INTRODUCTION
Systematic evaluation of the diagnostic value of next generation sequencing (NGS) in sepsis etiology.
METHODOLOGY
We conducted a systematic search on four databases (Web of Science, Cochrane, PubMed, and Embase) and compiled diagnostic experiments using NGS to evaluate sepsis etiology. Two researchers conducted research and obtained data independently.
RESULTS
Nine documents were included comprising 747 patients, 988 blood samples, 175 bronchoalveolar lavage fluid (BALF) samples, 16 cerebrospinal fluid samples, and one urine sample. The combined sensitivity of each study was 0.89 (95% CI: 0.82-0.95). The combined specificity was 0.40 (95% CI: 0.25-0.55). The combined positive likelihood ratio was 1.51 (95% CI: 1.18-1.98). The combined negative likelihood ratio was 0.28 (95% CI: 0.11-0.48). The diagnostic odds ratio (DOR) was 6.38 (95% CI: 2.53-15.32) and the area under the curve (AUC) was 0.84, (95% CI: 0.62-0.94).
CONCLUSIONS
Based on the data we collected, we found that compared with the blood culture technology, NGS has the advantages of high sensitivity and wide detection range, but its specificity was low. Further study is needed to confirm the value of NGS in the etiological diagnosis of patients with sepsis.

Meta-Analysis
BACKGROUND
Although laparoscopic lavage for perforated diverticulitis with peritonitis has been grabbing the headlines, it is known that the clinical presentation of peritonitis can also be caused by an underlying perforated carcinoma. The aim of this study was to determine the incidence of patients undergoing inadvertent laparoscopic lavage of perforated colon cancer as well as the delay in cancer diagnosis.
METHODS
The PubMed database was systematically searched to include all studies meeting inclusion criteria. Studies were screened through titles and abstracts with potentially eligible studies undergoing full-text screening. The primary endpoints of this meta-analysis were the rates of perforated colon cancer patients having undergone inadvertent laparoscopic lavage as well as the delay in cancer diagnosis. This was expressed in pooled rate % and 95% confidence intervals.
RESULTS
Eleven studies (three randomized, two prospective, six retrospective) totaling 642 patients met inclusion criteria. Eight studies reported how patients were screened for cancer and the number of patients who completed follow-up. The pooled cancer rate was 3.4% (0.9%, 5.8%) with low heterogeneity (Isquare2 = 34.02%) in eight studies. Cancer rates were 8.2% (0%, 3%) (Isquare2 = 58.2%) and 1.7% (0%, 4.5%) (Isquare2 = 0%) in prospective and retrospective studies, respectively. Randomized trials reported a cancer rate of 7.2% (3.1%, 11.2%) with low among-study heterogeneity (Isquare2 = 0%) and a median delay to diagnosis of 2 (1.5-5) months.
CONCLUSIONS
This systematic review found that 7% of patients undergoing laparoscopic lavage for peritonitis had perforated colon cancer with a delay to diagnosis of up to 5 months.

Meta-Analysis
BACKGROUND
Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) increases mortality risk, but which factors increase mortality is unknown. We aimed to perform a prognostic review of factors associated with mortality in patients with IPF.
STUDY DESIGN
and methods: We searched MEDLINE, EMBASE, and CINAHL for studies that reported on the association between any prognostic factor and AE-IPF. We assessed risk of bias using the QUIPS tool. We conduced pairwise meta-analyses using REML heterogeneity estimator, and GRADE approach to assess the certainty of the evidence.
RESULTS
We included 35 studies in our analysis. We found that long-term supplemental oxygen at baseline (aHR 2.52 [95 % CI 1.68 to 3.80]; moderate certainty) and a diagnosis of IPF compared to non-IPF ILD (aHR 2.19 [95 % CI 1.22 to 3.92]; moderate certainty) is associated with a higher risk of death in patients with AE-IPF. A diffuse pattern on high resolution computed tomography (HRCT) compared to a non-diffuse pattern (aHR 2.61 [95 % CI 1.32 to 2.90]; moderate certainty) is associated with a higher risk of death in patients with AE-IPF. We found that using corticosteroids prior to hospital admission (aHR 2.19 [95 % CI 1.26 to 3.82]; moderate certainty) and those with increased neutrophils (by % increase) in bronchoalveolar lavage (BAL) during the exacerbation is associated with a higher risk of death (aHR 1.02 [1.01 to 1.04]; moderate certainty).
INTERPRETATION
Our results have implications for healthcare providers in making treatment decisions and prognosticating the clinical trajectory of patients, for researchers to design future interventions to improve patient trajectory, and for guideline developers in making decisions about resource allocation.

Meta-Analysis
to update the 2016 systematic review evidence for vital pulp therapy (VPT) for primary teeth affected by caries or trauma. The population, intervention, comparison, outcomes, and study (PICOS) design inclusion/exclusion was used for multiple databases. Risk of bias, meta-analyses using RevMan, and certainty of evidence was created. A total of 299 studies were included; no trauma was found. Indirect pulp treatment (IPT) resulted in 97 percent success. Two calcium silicate cement (CSC) pulpotomies' success using mineral trioxide aggregate (MTA) and Biodentine were 94 percent and 90 percent, respectively, greater than for direct pulp capping (DPC; 86 percent) and other pulpotomies (moderate certainty). The success of IPT versus pulpotomy at 24 months showed no significant difference (P=0.31). Different liners or capping agents did not affect the success of IPT (P=0.79) or DPC at 24 months (P=0.24). The two CSC pulpotomies were not significantly different based on 24-month success (P=0.34). The formocresol pulpotomy success at 24 months was significantly lower than for MTA (P=0.02). Ferric sulfate had a significant lower success at 24 months than MTA pulpotomy (69 percent versus 92 percent; P=0.03). Zinc oxide eugenol, as a singular pulpotomy, had low success (65 percent). Selective/stepwise caries removal did significantly better at avoiding pulp exposures than complete excavation (P<0.001). Complete, selective, and no caries removal (Hall technique [HT], steel crown placement with no caries removal) had no significant difference in pulp vitality success for deep caries at 24 months (P=0.29). For deep caries affecting vital incisors, pulpotomy had significantly greater success than pulpectomy (P=0.002). The following had no significant effect on MTA pulpotomy success: coronal pulp removal methods; irrigation solution; method to control hemorrhage; base over MTA; treatment in one or two visits; and anterior or posterior teeth. Vital pulp therapy success of indirect pulp treatment or two calcium silicate cement pulpotomies demonstrated improved success over direct pulp capping and other pulpotomies based on 24-month evidence with moderate certainty. The Hall technique did not significantly reduce pulp vitality success versus caries removal.

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.

Commonly used isotonic arthroscopic irrigation fluids, such as normal saline or lactated Ringer's, were initially formulated for intravenous administration so they do not replicate the physiologic properties of healthy synovial fluid. Synovial fluid plays an important role in regulating joint homeostasis such that even transient disruptions in its composition and physiology can be detrimental. Previous studies suggest that hyperosmolar solutions may be a promising alternative to traditional isotonic fluids. This manuscript sought to systematically review and synthesize previously published basic science, translational, and clinical studies on the use of hyperosmolar arthroscopic irrigation fluids to delineate the optimal fluid for clinical use. A systematic literature search of MEDLINE/PubMed and Embase databases was performed in accordance with Preferred Reporting Items for Systemic Reviews and Meta-analyses (PRISMA) guidelines. The search phrases were: ("cartilage" AND "hyperosmolar"); ("arthroscopy" OR "arthroscopic" AND "hyperosmolar"). The titles, abstracts, and full texts were screened for studies on hyperosmolar solutions and articular cartilage. Study quality was assessed, and relevant data were collected. A meta-analysis was not performed due to study heterogeneity. A risk of bias assessment was performed on the included translational and clinical studies. There were 10 basic science studies, 2 studies performed in translational animal models, and 2 clinical studies included in this review. Of the basic science studies, 7 utilized a mechanical injury model. The translational studies were carried out in the canine shoulder and equine stifle (knee) joint. Clinical studies were performed in the shoulder and knee. Multiple basic science, translational, and clinical studies highlight the short-term safety, cost-effectiveness, and potential benefits associated with use of hyperosmolar solutions for arthroscopic irrigation. Further work is needed to develop and validate the ideal formulation for a hyperosmolar irrigation solution with proven long-term benefits for patients undergoing arthroscopic surgeries.

Meta-Analysis Review
Current treatment strategies in managing side effects associated with domiciliary positive airway pressure (PAP) therapy for patients with sleep disordered breathing: A systematic review and meta-analysis.
Sleep disordered breathing is commonly treated with positive airway pressure therapy. Positive airway pressure therapy is delivered via a tight-fitting mask with common side effects including: leak, ineffective treatment, residual sleep disordered breathing, eye irritation, nasal congestion, pressure ulcers and poor concordance with therapy. This systematic review and meta-analysis aimed to identify the effectiveness of current treatment strategies for managing side effects associated with positive airway pressure therapy. Five databases were searched and 10,809 articles were screened, with 36 articles included in the review. Studies investigated: dressings, nasal spray/douche, chin straps, heated humidification and interfaces. No intervention either improved or detrimentally affected: positive airway pressure concordance, Epworth Sleepiness Score, residual apnoea hypopnea index or interface leak. The review was limited by study heterogeneity, particularly for outcome measures. Additionally, patient demographics were not reported, making it difficult to apply the findings to a broad clinical population. This review highlights the paucity of evidence supporting treatment strategies to manage side effects of positive airway pressure therapy.

Meta-Analysis Review
PURPOSE
Extensive intraperitoneal lavage (EIPL) is a novel therapeutic intervention that aims to limit the chance of peritoneal metastasis during gastrectomy. Clinical trials on using EIPL after gastrectomy show controversial results. We aimed to summarize the evidence of efficacy and safety for using EIPL after gastrectomy to limit the possibility of peritoneal metastasis and improve survival.
METHODS
A literature search on PubMed, Scopus, Embase, and Web of Sciences was conducted till June 2023 to identify eligible RCTs that assess the efficacy and safety of EIPL after gastrectomy. The hazard ratio with 95% CI was used to determine the survival probability, the risk ratio with 95% CI was used to assess the surgical outcomes, and ROB-2 and GRADE guidelines were used to assess the risk of bias and the certainty of evidence respectively.
RESULTS
Six eligible studies with a total of 1993 patients were included in the meta-analysis. Regarding survival benefits, the survival of the EIPL group did not differ significantly from the non-EIPL group, and the pooled HR of overall survival was 0.86 (95% CI 0.58-1.26) P = 0.44, the disease-free survival was 0.81 (0.58-1.13) P = 0.21, and peritoneal recurrence-free survival was 0.97 (0.79-1.2) P = 0.25. There is no significant association between EIPL and short-term postoperative outcomes. The use of EIPL does not appear to affect postoperative mortality, infection, anastomotic leakage, bleeding, ileus, or hospital stay.
CONCLUSION
Our study yielded insufficient evidence about the survival benefits and surgical outcomes of EIPL in patients with gastric cancer after gastrectomy. Therefore, it is not recommended for treating gastric cancer patients.

The comparative of chitosan and chitosan nanoparticle versus ethylenediaminetetraacetic acid on the smear layer removal: A systematic review and meta-analysis of in vitro study.
The purpose of this systematic review of meta-analysis was to compare the effectiveness of removing the smearing layer using EDTA versus Chitosan (Ch) and Chitosan nanoparticles (Ch-NPs). A search was performed in four electronic databases (Web of Science, PubMed, Scopus, and Cochrane). The included studies were assessed by two reviewers using Joanna Briggs Institute's critical appraisal checklist for the quasi-experimental studies. Outcomes obtained by scanning electron microscopy (SEM) and conventional methods were presented as standardized mean differences alongside 95% confidence intervals. Seven investigations employed 212 single-root teeth. In the apical section (p = .317, 95% CI = -0.820 to 0.266, Tau = 0.387), middle segment (p = .914, 95% CI = -1.019 to 0.912, Tau = 1.027), and coronal segment (p = .277, 95% CI = -1.008 to 0.289, Tau = 0.378). This meta-analysis found no difference between Ch, Ch-NPs, and EDTA in removing the smear layer in the three segments. This systematic review is designed to show evidence related to the PICO question, in which our outcome is smear layer removal and not the clinical success of such a treatment. RESEARCH HIGHLIGHTS: The study aimed to compare the effectiveness of chitosan and chitosan nanoparticles with ethylenediaminetetraacetic acid (EDTA) in removing the smear layer, a layer of debris and organic material on the tooth surface, through a systematic review and meta-analysis. The removal of the smear layer is crucial for successful dental treatments, as it enhances the adhesion of restorative materials and improves the penetration of antimicrobial agents into dentinal tubules. The researchers conducted a systematic review and meta-analysis, searching various databases of electron microscopy results for relevant in vitro studies comparing the effects of chitosan or chitosan nanoparticles with EDTA on smear layer removal. The results encourage further exploration of chitosan and chitosan nanoparticles for clinical use in dentistry, while considering their specific applications and long-term effects.

PURPOSE
Prevention and management of postoperative pancreatic fistula (POPF) after pancreatic resections is still an unresolved issue. Continuous irrigation of the peripancreatic area is frequently used to treat necrotizing pancreatitis, but its use after elective pancreatic surgery is not well-known. With this systematic review, we sought to evaluate the current knowledge and expertise regarding the use of continuous irrigation in the surgical area to prevent or treat POPF after elective pancreatic resections.
METHODS
A systematic search of the literature was conducted according to the PRISMA 2020 guidelines, screening the databases of Pubmed, Scopus, Web of Science, and Ovid MEDLINE. Because of the heterogeneity of the included articles, a statistical inference could not be performed and the literature was reviewed only descriptively. The study was pre-registered online (OSF Registry).
RESULTS
Nine studies were included. Three studies provided data regarding the prophylactic use of continuous irrigation after distal and limited pancreatectomies. Here, patients after irrigation showed a lower rate of clinically relevant POPF, related complications, lengths of stay, and mortality. Six other papers reported the use of local lavage to treat clinically relevant POPF and subsequent fluid collections, with successful outcomes.
CONCLUSION
In the current literature, only a few publications are focused on the use of continuous irrigation after pancreatic resection to prevent or manage POPF. The included studies showed promising results, and this technique may be useful in patients at high risk of POPF. Further investigations and randomized trials are needed.
