001). Most of the patients would not seek help for their ED until the clinician directly or indirectly questioned them. Simple manipulations uncovered the hidden ED patients.Previous reports have demonstrated an association between rosacea and migraine1 . This relationship has been found especially among postmenopausal females in large register studies but also in some smaller clinical studies1 . A nationwide study (n=49,475) from Denmark reported that female subjects with rosacea aged over 50 years had 1.3-fold increased risk for migraine.Tim-3 is a negative immunoregulator in anti-tumor response, but its mechanism in chronic lymphocytic leukemia (CLL) is not yet clear. The aim of this study was to understand the role of Galectin-9/Tim-3 signaling pathway in the regulation of CD4+ T cell subsets in CLL patients. Flow cytometry results showed that the number of Treg cells obviously increased, and there was a significant Treg/Th17 imbalance in CLL patients. In addition, Tim-3 overexpressed on the surface of Th1 and Treg cells in CLL patients. The levels of Galectin-9 and IL-10 were significantly elevated in patients of CLL, especially in stages of Binet B, and C. However, IFN-γ decreased. PF-06952229 in vitro Moreover, Galectin-9 in CLL patients was positively correlated with the number of Tim-3+ Treg cells and the level of IL-10. Interestingly, when the Tim-3/Galectin-9 pathway was blocked in vitro, the level of IL-10 in the culture supernatant of CD4+ T was significantly reduced, while the levels of IFN-γ and TNF-α were increased. After co-culture with activated Th1 cells, the apoptosis of CLL cells was significantly increased, and this effect was reversed after treatment with Tim-3+ Tregs. In summary, Galectin-9/Tim-3 are elevated in CLL and associated with disease progression. By the negative regulation of CD4+ T cells, activated Galectin-9/Tim-3 suppresses Th1 effector function and also promotes Treg to be involved in immune escape of CLL. This pathway might become the potential target of immunotherapy in CLL patients. Acute acidosis can increase the plasma potassium concentration. However, data on the effects of acute respiratory acidosis on plasma potassium concentration are conflicting. This study aimed to determine whether acute respiratory acidosis induces an immediate increase in plasma potassium concentration. This observational study was conducted on participants undergoing apnoea testing prior to final radiological examination, registered in an internal quality registry at Oslo University Hospital between 25 April 2013 and 1 May 2020. A total of 124 donors were assessed for inclusion. Sixteen donors with blood glucose concentrations exceeding 10mmolL were excluded; finally, data from 108 donors were included in the study. The apnoea test, which is a standard neurological test performed in potential organ donors prior to radiological confirmation of ceased brain circulation, induces respiratory acidosis. The arterial plasma potassium concentration, pH and PaCO before and after the apnoea test were compared. Statistical analysis was conducted using the paired t test. The pre-apnoea and post-apnoea mean plasma potassium concentrations were 3.79 (95% confidence intervals [CI] 3.70-3.87) and 3.79mmolL (95% CI 3.70-3.88), respectively. The mean difference was -0.002mmolL (95% CI -0.04 to 0.04); the difference was not significant. The pre-apnoea and post-apnoea mean pH were 7.39 and 7.21, respectively, and the mean difference was 0.175 (P<.01). The pre-apnoea and post-apnoea mean PaCO were 5.66 and 9.48kPa, respectively, and the mean difference was -3.83 (P<.01). Acute respiratory acidosis does not lead to rapid changes in plasma potassium concentration during apnoea testing in potential organ donors.
