A Moment Dead, a Moment Alive: How a Situational Personhood Emerges in the Vegetative State in an Israeli Hospital Unit

ABSTRACT  Here we address the personhood of patients in a permanent vegetative state (PVS), who fall outside categories of "alive" or "dead" and "subject" or "object." Drawing on fieldwork in an Israeli hospital, we examine multiple and shifting approaches to PVS patients, which are articulated in the course of caring for and living with them. We argue that, alongside the institutional definition of these patients as being in a PVS, which, as Kaufman showed, evokes irresolvable confusion as to their ontological nature, there appear and disappear other senses of their personhood. Allying with other studies of cognitively impaired patients (e.g., those with dementia and Alzheimer's), we explore this relational person-concept while demonstrating its situational nature. We analyze patients' admission to the hospital, showing how their essentialistic personhood is "emptied" and how and when their fluid, relational personhood appears and disappears, further showing how this personhood is reified by imagined life stories.     

TNF-α depuration is a predictor of mortality in critically ill patients under continuous veno-venous hemodiafiltration treatment

IntroductionCritically ill patients with acute kidney injury (AKI) present high mortality rates. The magnitude of inflammatory response could determine the prognosis of such patients. Continuous renal replacement therapy (CRRT) may play an important role in removing inflammatory mediators in patients with AKI.AimTo investigate whether the magnitude of inflammatory mediator’s removal is associated with mortality among critically ill patients on CVVHDF, a CRRT modality.MethodsThis study consisted of 64 critically ill patients requiring CVVHDF. Plasma levels of C3a, TNF-α, IL-10, IL-6, IL-1β, sTNFRI and sTNFRII were determined by enzyme-linked immunosorbent assay (ELISA) at the beginning of CVVHDF and after 24 h (outlet). Clearance of cytokines during the first 24 h of CVVHDF was calculated. Clinical and laboratory data were acquired from patient’s records data.ResultsMean age of patients requiring CVVHDF was 63 years, 67.2% were men and 87.3% were Caucasian. Thirty-five (35) patients (54.7%) died. Comparing non-survivors with the group of survivors we observed higher incidence of sepsis (68.6 versus 37.9%, p < 0.05), higher APACHE II score (34.8 ± 7.6 versus 29.2 ± 7.1, p < 0.05) and higher lactate levels (23.2 ± 17.6 versus 16.4 ± 6.6, p < 0.05). According to the inter-tertile range of TNF-α clearance (ITR1 (<0.54); ITR2 (0.54–2.93); ITR3 (>2.93)) we found that those patients with higher TNF-α removal by RRT (ITR3) had a better survival. Multivariable analysis showed that lower clearance of TNF-α remained independently associated with high mortality after adjustment for sex, age, use of vasoactive drugs, APACHE II score sepsis, creatinine and lactate before CVVHDF (HR: 0.179, 95% IC: 0.049–0.661, p < 0.01).ConclusionThe attenuation of inflammatory response may be related to the lower mortality observed on those patients with higher TNF-α removal by CVVHDF.     

Catalytic antibodies from HIV-infected patients specifically hydrolyzing viral integrase suppress the enzyme catalytic activities

Human immunodeficiency virus type 1 integrase (IN) catalyzes integration of a DNA copy of the viral genome into the host genome. It was shown previously that IN preincubation with various oligodeoxynucleotides (ODNs) induces formation of dimers and oligomers of different gyration radii; only specific ODNs stimulate the formation of catalytically active dimers. Here we have shown that preincubation of IN with specific and nonspecific ODNs leads to a significant and comparable decrease in its hydrolysis by chymotrypsin, while nonspecific ODNs protect the enzyme from the hydrolysis by trypsin worse than specific ODNs; all ODNs had little effect on the IN hydrolysis by proteinase K. In contrast to canonical proteweases, IgGs from HIV‐infected patients specifically hydrolyze only IN. While d(pT)_n markedly decreased the IgG‐dependent hydrolysis of IN, d(pA)_n and d(pA)_n?d(pT)_n demonstrated no detectable protective effect. The best protection from the hydrolysis by IgGs was observed for specific single‐ and especially double‐stranded ODNs. Although IN was considerably protected by specific ODNs, proteolytic IgGs and IgMs significantly suppressed both 3′‐processing and integration reaction catalyzed by IN. Since anti‐IN IgGs and IgMs can efficiently hydrolyze IN, a positive role of abzymes in counteracting the infection cannot be excluded. Copyright © 2011 John Wiley & Sons, Ltd.
