Interaction of central angiotensin II and aldosterone on sodium intake and blood pressure.

Interaction of central angiotensin II and aldosterone on sodium intake and blood pressure. Brain Res. 2019 Jun 17;: Authors: Gasparini S, M R Melo, Nascimento PA, Andrade-Franzé GMF, Antunes-Rodrigues J, Yosten GLC, Menani JV, Samson WK, Colombari E Abstract Recent studies demonstrated an important natriorexigenic mechanism activated by aldosterone acting in the hindbrain. Studies have also shown that aldosterone effects are intensified by angiotensin II (ANG II) and vice-versa. Thus, the aim of the present work was to test if angiotensinergic mechanisms in the forebrain are involved on sodium appetite to aldosterone infused into the 4th V and also if aldosterone into the 4th V might facilitate ingestive and cardiovascular responses to central ANG II. Male Holtzman rats with stainless steel cannulas implanted into the 4th ventricle (4th V) and lateral ventricle (LV) had access to 1.8% NaCl during 2 hours/day. Chronic infusion of aldosterone (100 ng/h) into the 4th V for 7 days strongly increased 1.8% NaCl intake (16.1 ± 2.2 ml/2 h/day). Losartan (AT1 receptor antagonist, 50 µg/1 µl) acutely injected into the LV reduced 1.8% NaCl intake induced by aldosterone infusion into the 4th V (8.8 ± 2.3 ml/2 h/day). The pressor response to ANG II (50 ng/1 µl) into the LV increased in rats treated with aldosterone into the 4th V (45 ± 5 mmHg, vs. vehicle infusion: 26 ± 4 mmHg). Similarly, fluid intake (water + 1.8...

This study compared treatment failures between patients treated exclusively with IV antibiotics and those transitioned from IV to oral antibiotics for bacteraemia secondary to UTI.MethodsThis single-centre, retrospective cohort study included hospitalised, non-critically ill adult patients treated with culture-susceptible antibiotic therapy for 7–21 days. Patients were divided into two cohorts based on the route of definitive antibiotic administration. Treatment failure was a composite outcome of death and recurrence of the index micro-organism within 21 days following negative blood cultures.Results and discussionAm...

AbstractAplastic anemia (AA) has been reported to be associated with inflammatory bowel disease (IBD), but mostly with ulcerative colitis (UC). Little is known about the associations between AA and Crohn ’s disease (CD). We aim to determine the portraits of patients with AA-CD. Among a total of 657 patients with CD registered in Xijing Hospital of Digestive Diseases IBD center from January 2008 to October 2018, the patients diagnosed with concurrent AA were reviewed. Clinical presentation, medical history, endoscopic features, response to treatment, and prognosis in this set of patients were collected. Six male patie...

AbstractNodal peripheral T cell lymphomas (nPTCL) present aggressive clinical course, and its heterogeneous nature and poor prognosis with current therapeutic strategies make it a target for the development of new prognostic markers. Thus, we investigated tumor-associated macrophages (TAM) according to the number of cells expressing CD68 in biopsies and the absolute monocyte count (AMC) in peripheral blood of 87 patients with nPTCL. The median overall survival (OS) was 3  years (95% CI 1.3–8.4 years) and estimate 5 years OS of 43.3% (95% CI 32.5–53.7%). The median progression-free survival (PFS) ...

AbstractIncidence and outcome of microbiologically documented bacterial/viral infections and invasive fungal disease (IFD) in children and adults after hematopoietic cell transplantation (HCT) were compared in 650 children and 3200 adults in multicenter cross-sectional nationwide study. Infections were diagnosed in 60.8% children and 35.0% adults, including respectively 69.1% and 63.5% allo-HCT, and 33.1% and 20.8% auto-HCT patients. The incidence of bacterial infections was higher in children (36.0% vs 27.6%;p

In conclusion, efficacy data, the reassuring safety profile, and the novel mechanism of action of plitidepsin suggest that this combination can be an alternative option in patients with relapsed/refractory multiple myeloma after at least three prior therapy lines.
