AbstractObjectiveDespite the increasing dependence on systematic reviews to summarise the literature and to issue public health recommendations, the formal assessment of the reliability of conclusions emerging from systematic reviews has received little attention. The main goal of the present study was to evaluate whether two independent centres, in two continents, draw similar conclusions regarding the association of food, nutrition and physical activity and endometrial cancer, when provided with the same general instructions and with similar resources.DesignThe assessment of reproducibility concentrated on four main areas: (1) paper search and selection; (2) assignment of study design; (3) inclusion of ‘key’ papers; and (4) individual studies selected for meta-analysis and the summary risk estimate obtained.ResultsIn total 310 relevant papers were identified, 166 (54 %) were included by both centres. Of the remaining 144 papers, 72 (50 %) were retrieved in the searches of one centre and not the other (54 in centre A, 18 in centre B) and 72 were retrieved in both searches but regarded as relevant by only one of the centres (52 in centre A, 20 in centre B). Of papers included by both centres, 80 % were allocated the same study design. Agreement for inclusion of cohort-type and case–control studies was about 63 % compared with 50 % or less for ecological and case series studies. The agreement for inclusion of 138 ‘key’ papers was 87 %. Summary risk estimates from meta-analyses were similar.ConclusionsTransparency of process and explicit detailed procedures are necessary parts of a systematic review and crucial for the reader to interpret its findings.

Abstract Background: The hippocampus has for long been known for its abilities to form new, declarative memory. However, emerging findings across conditions in the psychosis spectrum also implicate its role in emotional regulation. Systematic reviews have demonstrated consistent volume atrophic changes in the hippocampus. The aim of the systematic review and metanalysis which will follow from this protocol will be to investigate the volume-based neuroimaging findings across each of the subfields of the hippocampus in psychosis independent of diagnosis.Methods: Volume changes across subfields of the hippocampus in psychotic illnesses will be assessed by systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). MRI neuroimaging studies of patients with a definitive diagnosis of psychosis (including brief pre diagnostic states) will be included. Studies lacking adequate controls, illicit drug use, medical psychosis, history of other significant psychiatric comorbidities or emphasis on age groups above 65 or below 16 will be excluded. Subfields investigated will include the CA1, CA2/3, CA4, subiculum, presubiculum, dentate gyrus, stratum, molecular layer, granular cell layer, entorhinal cortex and fimbria. Two researchers will independently conduct the search and selection procedures to gather suitable studies. One reviewer will independently perform all the data extraction, and another reviewer will then systemically check all the extracted information using the original articles to ensure accuracy. Statistical analysis will be performed using the metafor and meta packages in R Studio with application of the random effects model.Discussion: This study will provide insight into the volumetric changes in psychosis of the subfields of the hippocampus, independent of diagnosis. This may shed light on the intricate neural pathology which encompasses psychosis and will open avenues for further exploration of the structures identified as potential drivers of volume change.Systematic review registration: PROSPERO CRD42020199558

В первую очередь, острый аппендицит (ОА) - клинический диагноз. Согласно проведенному обзору, по всему миру заболеваемость острым аппендицитом составляет около 100 случаев на 100 тыс. населения в год. Острый аппендицит чаще встречается у пациентов от подросткового возраста и до 50 лет. Также определяется незначительное преобладание мужчин над женщинами. В 1894 г. McBurney описал новую по тем временам технику лечения острого аппендицита. Данный метод до сих пор используется, а во многих странах является золотым стандартом при оперативном лечении острого аппендицита. В 1981 году Семмом была произведена первая лапароскопическая аппендэктомия. В настоящее время хирургия с использованием эндовидео технологий приобретает первостепенное значение во многих хирургических учреждениях. Однако, даже с учетом большого количества проведенных операций и клинических исследований, среди хирургов возникает вопрос: является ли лапароскопическая операция оптимальным выбором при аппендэктомии. Цель. Сравнить лапароскопическую аппендектомию с открытой аппендектомией. Материалы и методы. Для поиска и отбора статей использовался принцип PRISMA (Предпочтительный Метод Отчета Для Систематических Обзоров и Метаанализов). В настоящем обзоре были использованы базы данных MedLine, Cochrane, PubMEd. Глубина поиска составила 10 лет, за исключением исторических данных. Все источники изучены без лимитирования по языку. Обзор литературы проводился в электронном и в ручном режимах. Для обзора были отобраны статьи, соответствующие ключевым словам - острый аппендицит, лапароскопическая аппендэктомия, открытая аппендэктомия. Было найдено 389 статьи, в поиск включались систематические обзоры, метаанализы, рандомизированные клинические исследования. Для удаления дубликатов и отбора статей использовался ресурс «https://rayyan.ai/» После отбора статей было выбрано 119 источников, которые были включены в итоговый синтез. Вывод. Лапароскопическая аппендектомия показывает преимущество перед открытой аппендектомией по интенсивности боли в первый день, раневым инфекциям, продолжительности пребывания в больнице и времени до возвращения к нормальной активности у взрослых. В нескольких исследованиях сообщалось о более высоких показателях качества жизни у взрослых. Однако, некоторые клинические эффекты лапароскопической аппендектомии описаны авторами как небольшие и имеющие ограниченное клиническое значение. Необходимы крупные исследования, направленные на снижение уровня систематической ошибки. First of all, acute appendicitis (OA) is a clinical diagnosis. According to the survey, the worldwide incidence of acute appendicitis is about 100 cases per 100 thousand rubles. population per year. Acute appendicitis is more common in patients from adolescence to 50 years of age. There is also a decisive predominance of men over women. In 1894, McBurney described a new technique for the treatment of acute appendicitis. This method is still used, it is used by the gold standard in the surgical treatment of acute appendicitis. In 1981, Semm performed the first laparoscopic appendectomy. Nowadays, surgery using endovideo technology is gaining paramount importance in many surgical institutions. However, even taking into account the large number of operations performed and clinical trials, the question arises among surgeons: is laparoscopic surgery the optimal choice for appendectomy? Target. Compare laparoscopic appendectomy with open appendectomy. Materials and methods. For the search and selection of articles, the PRISMA principle (Preferred Reporting Method for Systematic Reviews and Meta-analyzes) was used. In this review, the databases MedLine, Cochrane, PubMEd were used. Search depth excludes 10 years. All sources have been studied without language limitation. The literature review was carried out in electronic and manual modes. For were selected articles, the relevant keywords - acute appendicitis, laparoscopic appendectomy, open appendectomy. 389 articles were found, systematic reviews, meta-analyzes, randomized clinical trials were included in the search. To remove duplicates and select articles, the resource "https://rayyan.ai/" was used for the selection of articles, 119 sources were selected, which were included in the final synthesis. Output. Laparoscopic appendectomy shows an advantage over open appendectomy in first day pain, wound infections, length of hospital stay, and time to return to normal activity in adults. Several studies have reported higher rates of quality of life in adults. However, some of the authors' approximating effects of laparoscopic vendectomy are small and of limited clinical relevance. Large studies are needed, the error is to lower the systematic level.

Abstract. This editorial gives a brief introduction to the six articles included in the fourth “Hotspots in Psychology” of the Zeitschrift für Psychologie. The format is devoted to systematic reviews and meta-analyses in research-active fields that have generated a considerable number of primary studies. The common denominator is the research synthesis nature of the included articles, and not a specific psychological topic or theme that all articles have to address. Moreover, methodological advances in research synthesis methods relevant for any subfield of psychology are being addressed. Comprehensive supplemental material to the articles can be found in PsychArchives ( https://www.psycharchives.org ).
