Apolipoprotein E (APOE) is a multifunctional protein that plays significant roles in important cellular mechanisms in peripheral tissues and is as well expressed in the central nervous system, notably by adult neural stem cells (NSCs) in the hippocampus. Evidence from animal studies suggest that APOE is critical for adult NSC maintenance. However, whether APOE has the potential to play a similar role in human NSCs has not been directly investigated. To address this question, we conducted a focused study characterising APOE gene and protein expression in an in vitro model of neural differentiation utilising human induced pluripotent stem cells. We found that APOE gene expression was dramatically decreased as the cells became more differentiated, indicating that APOE expression levels reflect the degree of cellular differentiation during neural induction. Furthermore, qualitative analysis results of immunocytochemistry showed that intracellular localisation of APOE protein becomes more pronounced as neural differentiation progresses. Taken together, our findings suggest a potential role for APOE in human NSC maintenance and justify further investigations being carried out to understand whether changes in APOE levels can directly impact the neurogenic capacity of human stem cells.In this paper, we take up three terms - containment, delay, mitigation - that have been used by the UK Government to describe their phased response to the COVID-19 pandemic. Although the terms refer to a political and public health strategy - contain the virus, flatten the peak of the epidemic, mitigate its effects - we offer a psychosocial reading that draws attention to the relation between time and care embedded in each term. We do so to call for the development of a form of care-ful attention under conditions that tend to prompt action rather than reflection, closing down time for thinking. Using Adriana Cavarero's notion of 'horrorism', in which violence is enacted at precisely the point that care is most needed, we discuss the ever-present possibility of failures within acts of care. We argue that dwelling in the temporality of delay can be understood as an act of care if delaying allows us to pay care-ful attention to violence. We then circle back to a point in twentieth-century history - World War II - that was also concerned with an existential threat requiring a response from a whole population. Our purpose is not to invoke a fantasised narrative of 'Blitz spirit', but to suggest that the British psychoanalytic tradition born of that moment offers resources for understanding how to keep thinking while 'under fire' through containing unbearable anxiety and the capacity for violence in the intersubjective space and time between people. In conditions of lockdown and what will be a long and drawn-out 'after life' of COVID-19, this commitment to thinking in and with delay and containment might help to inhabit this time of waiting - waiting that is the management and mitigation of a future threat, but also a time of care in and for the present.[This retracts the article on p. 38 in vol. BMS-354825 concentration 10, PMID 32419975.].Burn injuries carry significant implications on short- and long-term quality of health. The present study undertook the first attempt to characterize generic and burn-specific quality of life and their predictors among adult burn patients admitted to a Lebanese burn care center. 130 adult patients admitted to the Lebanese Geitaoui Hospital burn center between 2013 and 2019 willingly answered Arabic versions of RAND's 36-Item Short Form Survey (SF-36), and the Burn-Specific Health Scale-Brief (BSHS-B). Results showed that burn patients continue to exhibit impairments on various generic and burn-specific quality of life subdomains. Education, pain and total body surface area (TBSA) burned were consistently and significantly correlated with both BSHS-B and SF-36 component scores, while inhalation injury exhibited an association with total BSHS-B score. Education and pain emerged as independent predictors of SF-36 components as well as total BSHS-B score. The latter was additionally associated with BMI and burn degree, while TBSA burned negatively correlated with SF-36 physical component scores. Correlates of impaired quality of life among Lebanese adult burn patients should therefore be taken into account and existing burn management practices and rehabilitation programs should be revised accordingly in order to ensure optimal long-term patient outcomes.
Decompressive craniectomy (DC) in severe traumatic brain injury (TBI) is associated with acute and late complications. To avoid these complications, we proposed a technical modification in DC. In this paper analyze a series of patients underwent to surgical treatment for acute subdural hematoma (ASDH).
We perform a prospective cohort with TBI patients undergoing DC for treatment of diffuse hemispheric brain swelling and ASDH. The effect of modified craniectomy was assessed using postoperative CT. Clinical outcome was evaluated at ICU mortality in 2 weeks.
Comparing the CT scans before and after surgery, the midline shift decreases from median of 11 mm to 5.5 mm (P<0.001). Only one patient had presented uncontrolled intracranial hypertension after surgery. Postoperative mortality in the intensive care unit within 14 days was 48.8%.
this is an interesting technical modification. In this pilot study, we observed ICP control, avoiding the complications of classical decompression.

Burn injuries can induce distinct, systemic inflammatory and immunological responses which occur acutely up to 72 hrs or chronically after 24 hrs. Previously published literature showed a dramatic increase in whole blood histamine values within 24 hrs of a thermal injury. However, the data is limited due to infrequent monitoring, resulting in statistically insignificant findings. The goal of this study was to determine localized histamine fluctuations for 6 consecutive days in a successive group of patients admitted immediately after a burn.
Using blood plasma from 7 patients (average total burn surface area 24.7%), we examined histamine within an average 4.1 (± 0.3) hrs from burn injury, by means of a monoclonal-based competitive binding enzyme immunoassay. Histamine values were normalized to patient baselines prior to determining overall averages. Patient vitals and electrolyte values were extracted from the electronic health record. A two-tailed student t-test was used to compare values with
-value ≤ 0.
