ObjectivesThe scientific community assumes that rigorous methodology research is more likely to be published in high impact psychiatry journals (HIJ). We aimed to test which methodological variables could predict publication in HIJ.MethodsWe conducted a systematic review of the MEDLINE and EMBASE databases from 2013, January 1st to 2015, June 15th. Inclusion criteria were studies that were RCTs whose at least one arm of the study should be fluoxetine regarding adult patients (> 18 years old) with MDD. We performed logistic regression regarding the number of participants, intention-to-treat analysis, blinding, multicenter study, sample losses, positive result, sponsorship of pharmacy's industry, and h-index of the last author. A HIJ was considered if journal impact factor was above the median or 3rd quartile of our sample.ResultsForty-two studies were considered for the final analysis. The results of the univariate logistic regression found no differences between HIJ and low impact psychiatry journals for all methodological variables, except the h-index of the last author. By considering HIJ when impact factor was above the mean, h-index had an odds ratio = 1.09 (1.01–1.17), P = 0.02; considering HIJ when impact factor was above the 3rd quartile, h-index had an odds ratio = 1.07 (1.01–1.14), P = 0.02.DiscussionOur results indicate that the author productivity may be a relevant predictor for publication in a HIJ in the psychiatry/psychology field. Our study proposes that journals focus on identifying what are the relevant criteria for publication approval in the peer-review process.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract Background Malaria is a major cause of morbidity and mortality in pediatrics in malaria endemic areas. Artemisinin-based combination therapies (ACTs) are the drugs of choice for malaria management particularly across malaria-endemic countries. This systematic review and meta-analysis was performed to assess efficacy and safety of ACTs for uncomplicated malaria in pediatric populations. Methods A body of evidence was searched for published ACT trials until March 06, 2020. The search was focused on efficacy and safety studies of ACTs for uncomplicated malaria in pediatrics. PubMed library was searched using best adapted search terms after multiple trials. References were exported to the endnote library and then to Covidence for screening. Data was extracted using the Covidence platform. The per-protocol analysis report for the efficacy and the intention-to-treat analysis for the safety were synthesized. Met-analysis was carried using Open Meta-Analyst software. Random effects model was applied and the heterogeneity of studies was evaluated using I2 statistic. Results Nineteen studies were included in the final analysis. Overall, crude, PCR-corrected P. falciparum malaria treatment success rate was 96.3 and 93.9% for day 28 and 42, respectively. In the subgroup analysis, PCR-corrected adequate clinical and parasitological response (ACPR) of dihydroartemisinin-piperaquine (DP) was 99.6% (95% CI: 99.1 to 100%, I2 = 0%; 4 studies) at day 28 and 99.6% (95% CI of 99 to 100%, I2 = 0%; 3 studies) at day 42. Nine studies reported ACT related adverse drug reactions (ADR) (8.3%, 356/4304). The reported drug related adverse reactions ranged from 1.8% in DP (two studies) to 23.3% in artesunate-pyronaridine (AP). Gastrointestinal symptoms were the most common ACT related adverse effects, and all ADRs were reported to resolve spontaneously. Conclusion ACTs demonstrated a high crude efficacy and tolerability against P. falciparum. The high treatment success and tolerability with low heterogeneity conferred by DP has implication for policy makers who plan the use of ACTs for uncomplicated falciparum malaria treatment in pediatrics.

AbstractObjectives To evaluate the type of peer review blinding used in highly ranked dental journals and to discuss the influence of the blinding approaches on the peer review process.Methods All 91 dental journals classified by impact factor (IF) had their websites scrutinised for the type of peer review blinding used for submissions. If the information was not reported, the journals were contacted to obtain the information. Linear and logistic regression were applied to evaluate the association between type of peer review blinding and IF.Results The selected journals reported the following peer review blinding approaches: single-blind (N = 36, 39.6%), double-blind (N = 46, 50.5%), transparent (N = 2, 2.2%) and open (N = 1, 1.1%). Information from six (6.6%) journals was not available. A linear regression analysis demonstrated that journals with lower IFs were associated with double-blind review (p = 0.001). A logistic regression suggested lower odds of association between single-blind peer review and journals with IFs below a threshold of 2 (odds ratio 0.157, confidence interval 0.059 to 0.417, p <0.001).Conclusions The majority of highly ranked dental journals had single- and double-blind peer review; journals with higher IFs presented single-blind peer review and those with lower IFs reported double-blind peer review.

Abstract Background Circulating sodium is analyzed by flame spectrometry and indirect or direct potentiometry. The differences between estimates returned by the three techniques are often relevant. It is unknown whether peer-reviewed international publications focusing on this parameter provide information about the technique. Objectives of the study were to ascertain if information about the employed technique is provided. Content A search in the National Library of Medicine for articles whose title contains “hyponatr[a]emia” was performed. We restricted the search to clinical reports including 10 or more humans published in the 2013–2015 and 2017–2019 periods. Authors of papers not reporting the technique were contacted to obtain this information. The study design and journal quartile ranking of each article were also evaluated. Summary For the final analysis, we included 361 articles (2013–2015, n=169; 2017–2019, n=192). Information about the laboratory technique was given in 61(17%) articles. Thanks to our inquiry, we collected this information for 116(32%) further reports. Indirect potentiometry was the most frequently used technique, followed by direct potentiometry. Spectrometry was used in a small minority of studies. Study design, journal ranking and study period did not modulate the mentioned frequency. Outlook Most articles focusing on hyponatremia do not provide information on the laboratory technique. This parameter is nowadays analyzed by indirect or, less frequently, direct potentiometry. The figures are similar for high and low impact factor journals and for the 2013–2015 and the 2017–2019 periods. Many authors, reviewers and editors likely assume that the results of this parameter are not influenced by the technique.

Abstract Background Some studies have looked at the age at menarche and risk of Multiple Sclerosis (MS).We aimed to conduct a systematic review and meta-analysis to estimate a pooled odds ratio of developing MS by increasing age at menarche. Methods We searched PubMed, Scopus, EMBASE, CINAHL, Web of Science, Ovid, google scholar and gray literature (references of references, congress abstracts) up to 10th April 2019. Results The literature search found 312 articles. After eliminating duplicates, reviews, case reports and trials, 18 articles remained. Three articles were ultimately included in the final analysis. Two studies were from Iran, and one from Canada. The pooled odds ratio (OR) for increasing 1 year of age at menarche was 0.88 (95% CI:0.82-0.94), with no significant heterogeneity (I2 = 49%, p = 0.1). Mean age at menarche was significantly different between case and control groups (mean difference = − 0.22, 95% CI = -0.42,-0.02). Conclusion The result of this systematic review showed that the risk of MS decreases by increasing age at menarche.

Journal Impact

Increasingly, academics have to demonstrate that their research has academic impact. Universities normally use journal rankings and journal impact factors to assess the research impact of individual academics. More recently, citation counts for individual articles and the h-index have also been used to measure the academic impact of academics. There are, however, several serious problems with relying on journal rankings, journal impact factors and citation counts. For example, articles without any impact may be published in highly ranked journals or journals with high impact factor, whereas articles with high impact could be published in lower ranked journals or journals with low impact factor. Citation counts can also be easily gamed and manipulated and the h-index disadvantages early career academics. This paper discusses these and several other problems and suggests alternatives such as post-publication peer review and open-access journals.

Abstract Background and study aims Despite the clinical efficacy of peroral endoscopic myotomy (POEM), postoperative symptomatic gastroesophageal reflux disease (GERD) remains a major concern. While it is known that length of the gastric myotomy affects postoperative GERD, the clinical relevance of variation in esophageal myotomy length is not well known. We performed a systematic review and meta-analysis of studies comparing outcomes of short versus standard myotomy length in patients with achalasia. Patients and methods We searched multiple databases from inception through November 2020 to identify studies that reported on outcomes of achalasia patients who underwent short compared with standard esophageal myotomy. Meta-analysis was performed to determine pooled odds ratio (OR) of clinical success, GERD outcomes, and adverse events with the two techniques. Results 5 studies with 474 patients were included in the final analysis (short myotomy group 214, standard myotomy group 260). There was no difference in clinical success (OR 1.17, 95 % confidence interval [CI] 0.54–2.52; I2 0 %; P = 0.69), postoperative symptomatic GERD (OR 0.87, 95 %CI 0.44–1.74; I2 29 %; P = 0.70), and overall adverse events (OR 0.52, 95 %CI 0.19–1.38; I2 40 %; P = 0.19), between the two groups. Incidence of postoperative erosive esophagitis as determined by endoscopy was lower in the short myotomy group (OR 0.50, 95 %CI 0.24–1.03; I2 0 %; P = 0.06). Conclusion Our analysis showed that performing POEM with short esophageal myotomy in achalasia was as safe and effective as standard myotomy, with lower incidence of postoperative erosive esophagitis.

Zusammenfassung.Hintergrund: Die Häufigkeit pflegewissenschaftlicher Beiträge aus dem deutschsprachigen Raum in Zeitschriften mit hohem Impact Factor gibt Hinweise auf die Teilhabe der Disziplin am internationalen Diskurs. Bisherige Analysen beschränken sich auf pflegewissenschaftliche Zeitschriften. Diese konstatieren eine Unterrepräsentanz experimenteller Studien und klinischer Themen. Ziel: Identifikation und Analyse der Publikationen von im deutschsprachigen Raum ansässigen Pflegewissenschaftlerinnen/Pflegewissenschaftlern in internationalen pflegerelevanten High Impact Journals. Methode: Mittels Journal Citation Reports wurden pflegerelevante Zeitschriftenkategorien identifiziert, in denen die nach dem 5-Jahres-Impact-Factor höchsten 10 % der Zeitschriften der Jahre 2010 bis 2014 ausgewählt wurden. Der Einschluss der Publikationen und die Datenextraktion erfolgten durch zwei unabhängige Personen. Ergebnisse: Durchsucht wurden 106939 Publikationen aus 126 Zeitschriften. Eingeschlossen wurden 100 Publikationen, an denen 114 Pflegewissenschaftler/-innen aus dem deutschsprachigen Raum insgesamt 229 Mal beteiligt sind. Insgesamt 42 % sind Beobachtungsstudien, 11 % sind experimentelle Studien. Die berichteten Themen sind mehrheitlich klinisch orientiert (55 %). Über 50 % sind in den letzten zwei Jahren publiziert worden. Schlussfolgerungen: Das pflegewissenschaftliche Publikationsaufkommen aus dem deutschsprachigen Raum in High Impact Journals ist gering. Eine Zunahme über den Beobachtungszeitraum ist zu verzeichnen. Im Gegensatz zu früheren Analysen zeigt sich ein höherer Anteil klinischer Forschung.
