CVD was more common in RA at cohort entry; stroke (3.9% vs 2.7%, p less then 0.001), heart failure (1.6% vs 1.0%, p=0.001), and non-significantly MI (3.1% vs 2.8%, p=0.092). Excess CVD developed in the 5 years preceding diagnosis. selleck After adjustment for traditional and RA-related risk factors, RA was associated with greater risk of post-diagnosis CVD (HR 1.33, 95% CI 1.07 to 1.65, p=0.010). CONCLUSIONS An excess of stroke and heart failure occurs before diagnosis of RA. There is excess risk for further cardiovascular events after diagnosis, which is not explained by differences in traditional CVD or RA-related risk factors at diagnosis. © Author(s) (or their employer(s)) 2020.

METHODS We retrospectively enrolled 87 consecutive patients (58±14 years, 55 women) who received anthracycline and underwent echocardiographic examinations both before (baseline) and after initial anthracycline administration (first follow-up). We measured absolute values of global longitudinal strain (GLS), apical longitudinal strain (LS), mid-LS and basal-LS at baseline and first follow-up, and per cent changes (Δ) of these parameters were calculated. Among 61 patients who underwent further echocardiographic examinations (second follow-up, third follow-up, etc), we assessed the association between regional left ventricular (LV) systolic dysfunction from baseline to follow-up and development of CTRCD, defined as LV ejection fraction (LVEF) under 53% and more absolute decrease of 10% from baseline, after first follow-up. RESULTS LVEF (65%±4% vs 63±4%, p=0.004), GLS (23.2%±2.6% vs 22.2±2.4%, p=0.005) and basal-LS (21.9%±2.5% vs 19.9±2.4%, p less then 0.001) at first follow-up significantly decreased compared with baseline. Among the 61 patients who had further follow-up echocardiographic examinations, 13% developed CTRCD. In the Cox-hazard model, worse Δbasal-LS was significantly associated with CTRCD. By Kaplan-Meier analysis, patients with Δbasal-LS decrease of more than the median value (-9.7%) had significantly worse event-free survival than those with a smaller decrease (p=0.015). CONCLUSIONS Basal-LS significantly decreased prior to development of CTRCD, and worse basal-LS was associated with development of CTRCD in patients receiving anthracycline chemotherapy. © Author(s) (or their employer(s)) 2020.

However, no prospective studies have investigated the long-term effects of tub bathing with regard to CVD risk. METHODS A total of 30 076 participants aged 40-59 years with no history of CVD or cancer were followed up from 1990 to 2009. Participants were classified by bathing frequency zero to two times/week, three to four times/week and almost every day. The HRs of incident CVD were estimated using Cox proportional hazards models after adjusting for traditional CVD risk factors and selected dietary factors. RESULTS During 538 373 person-years of follow-up, we documented a total of 2097 incident cases of CVD, comprising 328 coronary heart diseases (CHDs) (275 myocardial infarctions and 53 sudden cardiac deaths) and 1769 strokes (991 cerebral infarctions, 510 intracerebral haemorrhages, 255 subarachnoid haemorrhages and 13 unclassified strokes). The multivariable HRs (95% CIs) for almost daily or every day versus zero to two times/week were 0.72 (0.62 to 0.84, trend p less then 0.001) for total CVD; 0.65 (0.45 to 0.94, trend p=0.065) for CHD; 0.74 (0.62 to 0.87, trend p=0.005) for total stroke; 0.77 (0.62 to 0.97, trend p=0.467) for cerebral infarction; and 0.54 (0.40 to 0.73, trend p less then 0.001) for intracerebral haemorrhage. No associations were observed between tub bathing frequency and risk of sudden cardiac death or subarachnoid haemorrhage. CONCLUSION The frequency of tub bathing was inversely associated with the risk of CVD among middle-aged Japanese. © Author(s) (or their employer(s)) 2020. No commercial re-use.

Published by BMJ.Magnocellular neurosecretory cells are intrinsically osmosensitive and can be activated by increases in blood osmolality, triggering the release of antidiuretic hormone vasopressin (VP) to promote water retention. Hence, the activity of magnocellular VP neurons is one of the key elements contributing to the regulation of body fluid homeostasis in healthy organisms. Chronic exposure to high dietary salt leads to excessive activation of VP neurons, thereby elevating levels of circulating VP, which can cause increases in blood pressure contributing to salt-dependent hypertension. However, the molecular basis underlying high salt diet-induced hyperactivation of magnocellular VP neurons remains not fully understood. Previous studies suggest that magnocellular neurosecretory neurons contain a subcortical layer of actin filaments and pharmacological stabilization of this actin network potentiates osmotically-induced activation of magnocellular neurons. Using super-resolution imaging in situ, we investigated the orgasin secretion is a key factor controlling body fluid homeostasis, and excessive vasopressin secretion contributes to fluid balance disorders such as salt-sensitive hypertension. Using super-resolution analysis of different areas of the rat brain, we show that vasopressin neurons feature a unique actin cytoskeleton comprising a subcortical actin layer and an array of cytoplasmic comet-like structures, which are not present in any other neuronal cell type. Moreover, the density of these unique actin structures is increased in a rodent model of salt-sensitive hypertension, and our findings suggest that this modification may contribute to excessive activation of vasopressin neurons in a model salt-sensitive hypertension.
