The agonal phase of 173 potential DCD donors was characterized according to the presence or absence of: acidemia; lactic acidosis; prolonged (> 30 min) hypotension, hypoxia or oliguria, and the impact of these characteristics on 3- and 12-month transplant outcome evaluated by multivariable regression analysis. Of the 117 referrals who became donors, 27 (23.1%) arrested more than 1 h after WLST. Longer
agonal-phase times were associated with greater donor instability, but surprisingly neither agonal-phase instability nor its duration influenced transplant outcome. In contrast, 3- and 12-month eGFR in the 190 transplanted kidneys was influenced independently by donor age, and 3-month eGFR by cold ischemic time. DCD kidney numbers are increased by 30%, without compromising transplant outcome, by lengthening the minimum waiting time after WLST from 1 to 4 h.”
“The role of endothelin-1 (ET-1) and nitric Epigenetics inhibitor oxide (NO) as two important mediators in the development of cerebral vasospasm (CVS) after subarachnoid haemorrhage (SAH) is controversial. The objective of this study was to determine whether local levels of ET-1 and NO in cerebral arterial plasma and/or in cerebrospinal fluid (CSF) are associated with the occurrence of CVS Buparlisib nmr after SAH.
CVS was induced using the one-haemorrhage rabbit model and confirmed by digital subtraction angiography of the rabbits’ basilar artery on day
5. Prior to sacrifice, local CSF and basilar arterial plasma samples were obtained by a transclival approach to the basilar artery. Systemic arterial plasma samples were obtained. ET-1 levels were determined by immunometric technique (pg/ml +/- SEM) and total nitrate/nitrite level spectrophotometrically (A mu mol/l +/- SEM).
Angiographic CVS was documented after SAH induction (n = 12, P < 0.05). The ET-1 level in CSF was significantly elevated by 27.3% to 0.84 +/- 0.08 pg/ml in SAH animals (n = 7) in comparison to controls (0.66 +/- 0.04 pg/ml, n = 7, P < 0.05). There was no significant LY3023414 clinical trial difference in ET-1 levels in systemic
and basilar arterial plasma samples of SAH animals compared to controls. A significant lack of local NO metabolites was documented in basilar arterial plasma after SAH (36.8 +/- 3.1 A mu mol/l, n = 6) compared to controls (61.8 A +/- 6.2 A mu mol/l, n = 6, P < 0.01).
This study demonstrates that an elevated ET-1 level in CSF and local lack of NO in the basilar arterial plasma samples are associated with CVS after experimental SAH.”
“Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited condition associated with ventricular tachycardia (VT) triggered by exercise or sympathetic stress. Incessant VT may develop due to defibrillator-induced storminga condition where implantable cardioverter-defibrillator discharges result in a hyperadrenergic state, provoking further VT and defibrillator discharge.
