Primary Sjögren's syndrome (pSS) is an autoimmune disease characterized by exocrine gland dysfunction in combination with serious systemic disease manifestations. Myd88-dependent signaling networks remain incompletely understood in the context of pSS. The objective of this study was to establish the contribution of tissue-specific Myd88 activation to local (exocrine) and systemic pSS manifestations. To this end, we generated two novel conditional knockout pSS mouse models; one lacking Myd88 in hematopoietic cells and a second strain in which Myd88 was deleted in the stromal compartment. Spontaneous production of inflammatory mediators was altered in salivary tissue, and nephritis was diminished in both conditional knockout strains. In contrast, pulmonary inflammation was increased in mice lacking Myd88 in hematopoietic cells and was reduced when Myd88 was ablated in stromal cells. Finally, anti-nuclear autoantibodies (ANAs) were attenuated in pSS mice lacking Myd88 in immune cells. Additionally, the ANA-specific B cell repertoire was skewed in the Myd88-deficient strains. Collectively, these data demonstrate that Myd88 activation in specific cell types is essential for distinct aspects of pSS pathology.
Previous studies on ruptured intracranial aneurysms have shown favourable long-term outcomes of patients undergoing endovascular coiling compared to neurosurgical clipping. We aimed to evaluate if these results also apply to patients with unruptured intracranial aneurysms (UIAs).

Embase, PubMed, and Cochrane Library were systematically searched for all studies reporting long-term (≥3years) follow-up after coiling or clipping of UIAs. Thirteen studies involving 16,622 coiled patients and 13,606 clipped patients were included. Short-term outcome was defined as death ≤30days after treatment. Long-term outcomes (>3years) included all-cause mortality, morbidity (defined as modified Rankin Score 3-5 or Glasgow Outcome Score 2-3), cerebrovascular accident, intracerebral haemorrhage, additional repairs, and lost to follow-up. We calculated relative risk (RR), incidence and mortality rates (IR and MR), together with incidence and mortality rate ratio (IRR and MRR).

Patients treated with simple coiling had lower short-term mortality than clipped patients (RR=0.62 (95%CI 0.42-0.91)), but this difference disappeared after long-term follow-up ((MRR)=0.89 (95%CI 0.78-1.02). Coiled patients had higher retreatment rates than clipped patients (IRR=1.70 (95%CI 1.50-1.93)).

This systematic review and meta-analysis reports benefits and drawbacks of simple coiling versus neurosurgical clipping of UIAs. Future studies with longer follow-up time should account for differences in coiling techniques and confounding factors such as size and location of UIAs.

Labeling of diagnostic criteria using a rigorous iterative process of "aggregation" and "generalization" was conducted and inter-rater reliability calculation (Cohen's Kappa with three raters) was calculated. 241 criteria from 43 main sleep disorders of the ICSD-3 were labeled into nine types (Clinical manifestation 86.0% of sleep disorders, Objective markers 53.5%, Distress 30.2%, Disability 30.2%, Duration 30.2%, Frequency 58.1%, Age in 18.6%, Exclusion condition 81.4% and Associated condition 34.8%), with a high inter-rater reliability (Cohen's Kappa = 0.85). This analysis assumes that the structuring of the ICSD-3 diagnostic criteria is based on the Harmful Dysfunction Analysis (HDA). Some criteria correspond to the dysfunction part of the HDA while others refer to the harmful part. However, the approach does not seem to be homogeneous across the nosological classification. The use of a structured definition of sleep disorder and a framework to organize the ICSD diagnostic criteria is discussed with regard to the reliability and validity of criteria for diagnosing sleep disorders.Although pure Ti is nontoxic, alloying elements may be released into the surrounding tissue when Ti alloys are used, and this can cause cytotoxicity. Therefore, this study performed the damage evaluation of hydroxyapatite (HAp)-coated porous Ti components subjected to cyclic compression in a simulated body fluid (SBF). The HAp coating layer was deposited on the surface of porous Ti by electrophoresis, and a dense and homogeneous coating morphology was observed on the surface of the porous Ti. To specify damage types of HAp coating in situ, acoustic emission (AE) measurements and microscopic observations were simultaneously conducted during compressive fatigue loading tests to detect the specific failure mode. Compression tests revealed that the interfacial strength between the HAp coating and porous Ti was higher than the yield strength of the porous body (7-9 MPa). Tocilizumab chemical structure The AE signals were detected only in the plastic deformation stage of porous Ti, which indicated that they were generated because of plastic deformation/fractures in the porous body.
