2% to 3.6%. read more Simultaneous contact allergy to FM II and HICC was noted in 1.4% with the range 0.2% to 2.6%. Seventy-seven patients (0.31%) with contact allergy to HICC did not test positively to FM II. The range for missed HICC allergy by testing only FM II in the different centers would be 0.04% to 0.74%. The ratio between the contact allergy rates for FM II and HICC was similar for all centers, except for Montreal having significantly more contact allergy to FM II than to HICC. CONCLUSIONS The frequency of missed contact allergy to HICC when testing only with FM II was less than 0.5%, therefore questioning the need to test HICC separately in the ICDRG baseline series.OBJECTIVE To investigate the risk of bleeding events in older patients under oral anticoagulant with a four-year survey of a catchment area with 197722 inhabitants of whom 15267 on warfarin and 10397 on direct oral anticoagulants (DOACs). METHODS Patients presented to the Emergency Department with major bleeding were enrolled and stratified according to age ≥75 years and ongoing warfarin or DOACs. Primary endpoint was one-month death. RESULTS Out of 1919 major bleeding, those of patients aged ≥75 years were 1127(59%) versus 792(41%) aged less then 75 years, p less then 0.0001. In patients aged ≥75 years, brain hemorrhage accounted for 612(54%) patients, gastrointestinal hemorrhage for 301(27%), haematuria for 104(9%), and other hemorrhage for 108(10%). In patients aged ≥75 years, those on warfarin accounted for 175 versus 53 on DOACs, without difference of Charlson Comorbidity Index (5.25 ± 1.92 versus 5.09 ± 1.61; p=0.5824). One-month death in patients aged ≥75 versus less then 75 years accounted for 77(4,0%) versus 20(1,0%); p less then 0.0001. One-month death in patients aged ≥75 on DOACs was very low, without difference versus less then 75 years and within DOACs. Among DOACs, absolute bleeding events showed differences as follows 3 bleeding events for edoxaban versus 21 for dabigatran; p less then 0.001; versus 16 for rivaroxaban, p=0.006; and versus 13 for apixaban, p=0.02. CONCLUSIONS Major bleeding and one-month death accounted for higher percentage in patients aged ≥75 years and in patients receiving warfarin. read more Among DOACs, edoxaban presented the lowest absolute rate of hemorrhage and dabigatran the highest, without difference in mortality. Occupational quartz exposure is a health risk, with increased risk of developing lung, autoimmune diseases and elevated mortality in cardiovascular diseases. METHODS The population was obtained from the period 2005-2016 and consisted of 5 237 cases of patients with atrial fibrillation. Quartz exposure information was obtained through a Swedish job exposure matrix. RESULTS The risk of developing atrial fibrillation was increased for the quartz-exposed male population who were within a year of having commenced employment OR 1.54; (95% CI 1.06-2.24); this increased in the age group 20-55 (OR 2.05; CI 95% 1.02-4.10). CONCLUSION Our main conclusion is that quartz dust exposure may be related to increased risk of AF in high exposed (above 0.05 mg/m3 mean quartz dust) in men age 20-55 year. Hypertension is a growing health concern worldwide. Established hypertension is a causative factor of heart failure, which is characterized by increased vascular resistance and intractable uncontrolled blood pressure. Hypertension and heart failure have multiple causes and complex pathophysiology but cellular immunity is thought to contribute to the development of both. Recent studies showed that T cells play critical roles in hypertension and heart failure in humans and animals, with various stimuli leading to the formation of effector T cells that infiltrate the cardiovascular wall. Monocytes/macrophages also accumulate in the cardiovascular wall. Various cytokines (e.g. interleukin-6, interleukin-17, interleukin-10, tumor necrosis factor-α, and interferon-γ) released from immune cells of various subtypes promote vascular senescence and elastic laminal degradation as well as cardiac fibrosis and/or hypertrophy, leading to cardiovascular structural alterations and dysfunction. Recent laboratory evidence has defined a link between inflammation and the immune system in initiation and progression of hypertension and heart failure. Moreover, cross-talk among natural killer cells, adaptive immune cells (T cells and B cells), and innate immune cells (i.e. monocytes, macrophages, neutrophils, and dendritic cells) contributes to end-cardiovasculature damage and dysfunction in hypertension and heart failure. Clinical and experimental studies on the diagnostic potential of T-cell subsets revealed that blood regulatory T cells, CD4 cells, CD8 T cells, and the ratio of CD4 to CD8 T cells show promise as biomarkers of hypertension and heart failure. Therapeutic interventions to suppress activation of these cells may prove beneficial in reducing end-organ damage and preventing consequences of cardiovascular failure, including hypertension of heart failure.Multiple sclerosis (MS) is an autoimmune disease characterized by T cell infiltration and demyelination of the central nervous system (CNS). Experimental autoimmune encephalomyelitis (EAE) is a classical preclinical animal model of MS. In this study, we found that rotating magnetic field (RMF) treatment exerts potential preventive effects on the discovery of EAE, including reducing the severity of the disease and delaying the onset of the disease. The results indicated that RMF (0.2 T, 4 Hz) treatment increases the accumulation of CD4+ cells in the spleen and lymph nodes by downregulating the expression of CCL-2, CCL-3 and CCL-5, but has no significant effect on myelin oligodendrocyte glycoprotein (MOG) specific T cell responses. Simultaneously, RMF treatment adjusted the imbalance between regulatory T (Treg) cell and T helper 1 (Th1) cells or T helper 17 (Th17) cells by increasing the proportion of Treg cells and inhibiting the ratio of Th1 and Th17 cell subsets. These findings suggest that exposure to RMF may improve EAE disease by promoting CD4+ cell accumulation into peripheral lymphoid tissue, improving the imbalance between Treg and Th1/Th17 cells. Therefore, as a mild physical therapy approach, RMF, is likely to be a potential way to alter the development of EAE.
