Publishing in open access era: focus on respiratory journals

We have entered an open access publishing era. The impact and significance of open access is still under debate after two decades of evolution. Open access journals benefit researchers and the general public by promoting visibility, sharing and communicating. Non-mainstream journals should turn the challenge of open access into opportunity of presenting best research articles to the global readership. Open access journals need to optimize their business models to promote the healthy and continuous development.

腹腔镜与开腹胃癌根治术后早期并发急性胰腺炎的临床回顾性分析

目的本研究分析腹腔镜手术和开腹手术在胃癌治疗中伴发急性胰腺炎(post--gastrectomy acute pancreatitis,PGAP)的优劣性。方法收集2011年6月至2015年9月施行胃癌根治术的病人1050例。分别统计腹腔镜组和开腹组术后PGAP病例,并做回顾性分析对比研究。结果1050例胃癌根治术中并发PGAP的16例,发生率为1.52%,腹腔镜组432例,PGAP 7例,发生率为1.62%;开腹组618例,PGAP 9例,发生率为1.46%。腹腔镜组与开腹组术后PGAP发生率比较差异无统计学意义(x~2=0.046,P0.05)。腹腔镜组中远端胃251例,PGAP 1例(0.40%);近端胃78例,PGAP 1例(1.28%);全胃83例,PGAP 2例(2.41%);联合脏器切除20例,PGAP 3例(15.00%)。远端胃、近端胃和全胃切除术后PGAP发生率比较差异无统计学意义(P0.05),但三者与联合脏器切除术后PGAP发生率比较差异有统计学意义(P0.05)。开腹组中远端胃213例,PGAP 3例(1.41%);近端胃182例,PGAP 1例(0.55%);全胃174例,PGAP 2例(1.15%);联合脏器切除49例,PGAP 3例(6.12%)。结果类似腹腔镜组,远端胃、近端胃和全胃切除术后PGAP发生率比较差异无统计学意义(P0.05),但三者与联合脏器切除术后PGAP发生率比较差异有统计学意义(.P0.05)。腹腔镜组与开腹组分别对远端胃、近端胃、全胃和联合脏器切除后PGAP的发生率比较,差异均无统计学意义(P0.05)。结论腹腔镜与传统开腹胃癌根治术对于PGAP具有同样安全性。     

Treatment of Umbilical Granuloma in Infants With Topical Application of Common Salt: A Scoping Review

BackgroundCommon salt is a safe, effective and cheap home-made remedy for umbilical granuloma. The aim of this scoping review is to identify and summarize the available evidence and examine the research conducted on salt treatment for umbilical granuloma.MethodsA literature search was performed in the second week of September, 2022 using Google scholar, PubMed, MEDLINE and EMBASE databases using the keywords ‘umbilical granuloma’ and ‘salt treatment’ to identify all English articles pertaining to salt treatment for umbilical granuloma. Tables were made to summarize the methodological characteristics, results and the dosage regimens of salt used by different authors. The Cochrane Collaboration's tool was used for assessing risk of bias in RCTs. The indexing statuses of the journals publishing these studies were also noted. The overall efficacy with the use of common salt was calculated by adding the success rates mentioned in each study.ResultsTwenty-four articles (2 systematic reviews, 6 Randomized Controlled Trials, 11 prospective cohort studies, 1 case control study, 3 retrospective case series and 1 case report) were included. An overall 93.91% success rate (1033/1100) was seen with common salt application, without any reports of complications/recurrences.ConclusionTopical application of common salt for umbilical granulomas is simple, effective and inexpensive. This scoping review provides a broader outlook at the existing level of evidence and may help in planning interventional comparative studies, so that recommendations can be formulated. It also highlights a lack of properly designed randomized controlled trials on this topic.Level of EvidenceI.     

Risk factors for complications and in-hospital mortality: An analysis of 19,834 open pelvic ring fractures

BackgroundOpen pelvic fractures are rare injuries, associated with high patient morbidity and mortality. Few studies have investigated the impact of patient demographics, comorbidities, and injury related factors on complication and mortality rates. The purpose of this study was to: (1) identify the overall incidence of complications and mortality after open pelvic fractures, (2) compare patient factors between those who did and did not develop complications, (3) identify perioperative independent risk factors for complications and mortality.MethodsA query was performed for patients with open pelvic fractures between 2007 and 2017 using the American College of Surgeons National Trauma Data Bank. Patient and injury specific variables were collected and complications were identified using International Classification of Disease Ninth and Tenth edition Codes. Patient demographic and perioperative data was compared using Fisher’s exact test and chi-square test for categorical variables, and Welch’s t-test for continuous variables. Using pooled data from multiple imputations, logistic regressions were used to calculate odds ratios and confidence intervals of independent risk factors for complications.ResultsA total of 19,834 open pelvic fracture cases were identified, with 9622 patients (48.5%) developing at least one complication. Patients who developed complications were older (35.0 vs 38.1 years), and had higher Injury Severity Scores (17.7 vs 26.5), lower Glasgow Coma Scores (14.2 vs 11.7), and a larger proportion presenting with hypotension (21% vs 6.9%). After pooled regression involving 19 factors, these were the strongest independent predictors of inpatient complication and mortality.ConclusionWe report a mortality rate of 14%, with an inclusive complication rate of 48.5%. Evaluating risk factors for morbidity and mortality for this devastating orthopaedic injury provides knowledge of an inherently sparse population.Level of EvidenceLevel II, Retrospective study.
