This review will summarize recent data defining the relationship between rheumatoid arthritis (RA) and the microbiome at mucosal sites throughout the body. It will highlight what is known, what is speculated, and current knowledge gaps regarding the microbiome in RA.

An extensive relationship between the microbiome and immune cell function can influence RA-related inflammation and T cell and B cell biology. Studies are beginning to characterize microbial changes in individuals who are at risk for RA, which is a critical element needed to understand the influence of the microbiome on RA pathogenesis. Expanding our understanding of the microbiome in RA beyond the bacteria at the gut and oral mucosae into the lung and urogenital surfaces, including viral and fungal components, and establishing the relationship across mucosal sites will be critical in future work. Importantly, approaches to manipulate the microbiome could lead to novel therapeutic and preventive strategies.

As the use of diagnostic medical imaging has steadily increased over the past few decades with the increased availability of computed tomography (CT) and magnetic resonance imaging (MRI), so has the detection of incidental aneurysms. The management of an unruptured intracranial saccular aneurysm is challenging for both patients and physicians, as the decision to intervene must weigh the risk of rupture and resultant subarachnoid hemorrhage against the risk inherent to the surgical or endovascular procedure. The purpose of this paper is to provide an overview of factors to be considered in the decision to offer treatment for unruptured intracranial aneurysms in adults. In addition, we review aneurysm and patient characteristics that favor surgical clipping over endovascular intervention and vice versa. Finally, the authors propose a novel, simple, and clinically relevant algorithm for observation versus intervention in unruptured intracranial aneurysms based on the PHASES scoring system.Randomized controlled trials (RCTs) are considered to represent the gold standard of scientific studies and paved the way for evidence-based medicine (EBM). Besides the initial aim to improve the quality of patient care, EBM is used in the meanwhile for political and economic decision-making and legal issues as well. A review of the literature was performed, followed by a search using links and references of the detected articles. Additionally, homepages for German institutions of public health were screened. ABTL0812 Substantial limitations of RCTs and EBM health care could be identified. Based on the selected literature, 80% of the medical treatments have low evidence. RCTs are expensive and are mainly performed by the industry nowadays. A publication bias for positive results exists. Some RCTs are of low external validity. Many studies have a low fragility index. Nonetheless, negative RCTs could be of benefit for the patients. The results of RCTs, gained in a distinct patient population, are partially generalized. RCTs should be analyzed critically before adopting the results to daily clinical routine. It is not really justified to use RCTs and EBM for political and economic decision-making and legal issues as seen today.A Gram-stain-negative, non-pigmented, curved rod-shaped, single polarly flagellated, facultatively anaerobic bacterium, designated as SSH23T, was isolated from surface seawater sample collected at the Sehwa Beach in South Korea. The novel isolate required NaCl for growth and grew optimally between 2 and 3% NaCl. Strain SSH23T showed high 16S rRNA gene sequence similarities with Reinekea marinisedimentorum DSM 15388T (96.4%), Reinekea marina KACC 17315T (96.2%), Reinekea blandensis KACC 17315T (95.9%) and Reinekea aestuarii KCTC 22813T (95.6%). The major polar lipids of strain SSH23T were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The major cellular fatty acids of strain SSH23T were C160, summed feature 3 (C161 ω7c and/or C161 ω6c), and summed feature 8 (C181 ω7c and/or C181 ω6c). The predominant respiratory quinone was found to be ubiquinone-8. The average nucleotide identity values of strain SSH23T with R. marinisedimentorum DSM 15388T and R. blandensis MED297T were determined to be 72.2% and 69.8%, respectively. The G+C content of the genomic DNA was 45.5 mol%. Based on genotypic, phenotypic, chemotaxonomic, and phylogenetic analyses, strain SSH23T was considered to represent a novel member of the genus Reinekea, for which the name Reinekea thalattae sp. nov. is proposed. The type strain of Reinekea thalattae is SSH23T (= KACC 21168T = NBRC 113795T).An aerobic, Gram-stain-negative, non-motile, non-spore-forming, rod-shaped and pink-colored bacterial strain, designated BRD72T, was isolated from a crater lake (Baengnokdam) at the top of Mt. Hallasan in the Republic of Korea. Cells were catalase-positive and oxidase-negative. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the isolate was a member of the genus Hymenobacter and most closely related to Hymenobacter marinus KJ035T (96.2% similarity). The isolate was found to produce carotenoid pigment, but not flexirubin-type pigment. The predominant fatty acids of strain BRD72T were summed feature 3 (C161 ω7c and/or C161 ω6c, 21.6%), iso-C150 (17.9%), anteiso-C150 (13.3%) and summed feature 4 (iso-C171 I and/or anteiso-C171 B, 11.3%). The major polar lipids were phosphatidylethanolamine, an unidentified amino lipid, and two unidentified aminophospholipids. The main respiratory quinone was menaquinone-7 (MK-7), and the main polyamine was homospermidine. The DNA G+C content was 59.8 mol%.
