TRAIL-R1 and TRAIL-R2 Mediate TRAIL-Dependent Apoptosis in Activated Primary Human B Lymphocytes
In conclusion, this study provides a systematic analysis of the expression of TRAIL-Rs in human primary B cells and of their capacity to signal and induce apoptosis. This dataset forms a basis to further study and understand the dysregulation of TRAIL-Rs and TRAIL expression observed in autoimmune diseases. Additionally, it will be important to foresee potential bystander immunomodulation when TRAIL-R agonists are used in cancer treatment. Introduction The homeostasis of humoral immunity requires a tight control of generation, survival, activation and maturation of B lymphocytes. Therefore, pro-survival and pro-apoptotic signals play a very important role in shaping the B cell repertoire and the long-term memory compartment. Activation-induced cell death (AICD) is a key mechanism in the control of cell expansion and selection in the germinal center (GC), where B cells are activated and change their affinity for the antigen via somatic hypermutation (1). B cells with reduced specificity or with self-reactive B cell receptors should be eliminated (2, 3). Several members of the tumor necrosis factor (TNF) receptor superfamily have been implicated in the control of B cell homeostasis. Among these, Fas (CD95, Apo-1) is involved in the control of B cell activation and GC selection (4). Mutations in Fas lead to lymphoproliferation of B and T cells, and to autoimmunity (5, 6). TNF-related apoptosis-inducing ligand receptor (TRAIL-R) 1 (aka DR4 or TNFRSF10A) and TRAIL-R2 (aka...

Systematic searching (PubMed/Medline, Scopus, Embase, Web of Science, Cinhal, Wiley, Cochrane, Psychoinfo, ProQuest and Google Scholar) was done, up to March 2018 for ca...
Conclusions: Adding albumin to early standard resuscitation with lactated Ringer’s in cancer patients with sepsis did not improve 7-day survival.
Conclusions: Cell cycle arrest biomarkers, TIMP-2 and IGFBP7, improve risk stratification for severe outcomes in patients with stage 1 acute kidney injury by urine output, serum creatinine or both, with risk increasing with each acute kidney injury indicator. Longer term outcomes demonstrate that the associated risks of a [TIMP-2]•[IGFBP7] greater than 2.0 is equivalent to acute kidney injury progression even where no progression from stage 1 acute kidney injury is observed.

Objective: Cancer and its treatment are known to be important risk factors for sepsis, contributing to an estimated 12% of U.S. sepsis admissions in the 1990s. However, cancer treatment has evolved markedly over the past 2 decades. We sought to examine how cancer-related sepsis differs from non–cancer-related sepsis. Design: Observational cohort. Setting: National Readmissions Database (2013–2014), containing all-payer claims for 49% of U.S. population. Patients: A total of 1,104,363 sepsis hospitalizations. Interventions: We identified sepsis hospitalizations in the U.S. National Readmissions Dat...
Conclusions: The results suggest that these polymorphisms probably has not a substantial role in Iranian CRC risk and is not a serious potential factor in risk assessment of mentioned disease among Iranians. PMID: 31523666 [PubMed]

Acta Chir Orthop Traumatol Cech. 2019;86(4):286-289 Authors: Holoubek J, Lipový B Abstract The consequences of deep burns to the hands and face are the most challenging we encounter in modern reconstructive surgery. In many cases, the simple autotransplantation of full-thickness defects with split-thickness skin grafts is now considered inadequate or outdated. For this and many other reasons, the use of dermal substitution i...
CONCLUSIONS Intraarticular vancomycin and teicoplanin maximale tolerable and maintenance doses can be safely used beside surgery and intravenous antibiotics to increase efficacy of treatment, reduction of recurrence rates and reduction of mortality in MRSA septic arthritis. Key words:arthritis, infectious; methicillin-resistant Staphylococcus aureus; mortality. PMID: 31524589 [PubMed - in process]
