Abstract

INTRODUCTION: Postcardiotomy veno-arterial extracorporeal membrane oxygenation (V-A-ECMO) is associated with significant mortality. Identification of patients at very high risk for death is elusive and the decision to initiate V-A-ECMO is based on clinical judgment. The prognostic impact of pre-V-A-ECMO arterial lactate level in these critically ill patients has been herein evaluated.

METHODS: A systematic review was conducted to identify studies on postcardiotomy VA-ECMO for the present individual patient data meta-analysis.

RESULTS: Overall, 1269 patients selected from 10 studies were included in this analysis. Arterial lactate level at V-A-ECMO initiation was increased in patients who died during the index hospitalization compared to those who survived (9.3 vs 6.6 mmol/L, < 0.0001). Accordingly, in hospital mortality increased along quintiles of pre-V-A-ECMO arterial lactate level (quintiles: 1, 54.9%; 2, 54.9%; 3, 67.3%; 4, 74.2%; 5, 82.2%, < 0.0001). The best cut-off for arterial lactate was 6.8 mmol/L (in-hospital mortality, 76.7% vs. 55.7%, < 0.0001). Multivariable multilevel mixed-effect logistic regression model including arterial lactate level significantly increased the area under the receiver operating characteristics curve (0.731, 95% CI 0.702-0.760 vs 0.679, 95% CI 0.648-0.711, DeLong test < 0.0001). Classification and regression tree analysis showed the in-hospital mortality was 85.2% in patients aged more than 70 years with pre-V-A-ECMO arterial lactate level ≥6.8 mmol/L.

CONCLUSIONS: Among patients requiring postcardiotomy V-A-ECMO, hyperlactatemia was associated with a marked increase of in-hospital mortality. Arterial lactate may be useful in guiding the decision-making process and the timing of initiation of postcardiotomy V-A-ECMO.

We present the experimental realization of plasmonic hyperdoped Si nanocrystals embedded in silica via a combination of sequential low energy ion implantation and rapid thermal annealing. We show that phosphorus dopants are incorporated into the nanocrystal cores at concentrations up to six times higher than P solid solubility in bulk Si by combining 3D mapping with atom probe tomography and analytical transmission electron microscopy. We shed light on the origin of nanocrystal growth at high P doses, which we attribute to Si recoiling atoms generated in the matrix by P implantation, which likely increase Si diffusivity and feed the Si nanocrystals. We show that dopant activation enables partial nanocrystal surface passivation that can be completed by forming gas annealing. Such surface passivation is a critical step in the formation of plasmon resonance, especially for small nanocrystals. We find that the activation rate in these small doped Si nanocrystals is the same as in bulk Si under the same doping conditions.

Hypercalcemia is common in patients with advanced head and neck squamous cell carcinoma (HNSCC). In this study, hypercalcemia was detected in 46 (51%) of 90 eligible patients with HNSCC over 4 years. Compared with nonhypercalcemics, hypercalcemics were more likely to be referred to palliative care, while they were inpatients (P = 0.004). During the last 3 months of follow-up, hypercalcemic patients were more likely than nonhypercalcemics to be hospitalized for ≥ 14 days (P = 0.01) and to visit the emergency room more than once (P = 0.04). The median survival from the first hypercalcemic episode was 74 days (95% CI, 0.234). With data calculated from the date of referral to palliative care, hypercalcemics had a shorter survival than did nonhypercalcemics (43 vs 128 days, respectively; P = 0.046). Early detection and management of hypercalcemia in patients with HNSCC may improve the chance of preventing distressing symptoms and reducing unnecessary frequent emergency room visits and lengthy hospitalization.

Galal, N., H. Fouad, A. Saied, and M. Dabnon, Hyperammonemia in the pediatric emergency care setting., , 2010. Abstract

Hyperammonemia is encountered frequently in acutely ill children presenting for emergency care with altered levels of consciousness (ALOC). Ammonia production, metabolism, and excretion are affected by different variables. Hyperammonemia may be a transient state or may signify more grave etiologies as inborn errors of metabolism. Levels of ammonia are also affected by proper sampling technique, transport, and analysis.

OBJECTIVES:

To determine the level of ammonia in acutely ill children with ALOC, identify causes of hyperammonemia, and correlate levels with illness severity and morbidity.

DESIGN:

Observational study.

SETTING:

Emergency department at Cairo University Specialized Paediatric Hospital.

METHODS:

Fifty cases of acutely ill pediatric patients with ALOC who presented to the emergency department were included in the study from 2008 through 2009. Emergency department patients (n = 20) with known diseases that may induce hyperammonemia were excluded. Patients were subjected to detailed history taking with emphasis on factors affecting ammonia levels and thorough clinical examination. A cohort group of age- and sex-matched children acted as a control group.

RESULTS:

The measured blood ammonia level ranged between 13 and 265 μmol/L, with a mean level of 95 μmol/L. Sixty percent of the children with ALOC had ammonia levels of greater than 75 μmol/L, with levels greater than 200 μmol/L seen in 6% of the studied sample. The study demonstrated a highly significant statistical difference between children with ALOC and control groups.There was no correlation between blood ammonia level and age. Correlations of ammonia levels were also conducted in comparison with etiological diagnoses and laboratory parameters with no statistical significance.There was no statistical significance between ammonia level and duration of illness, Sequential Organ Failure Assessment score, or Glasgow Coma Scale score/Morray Scale score.

CONCLUSIONS:

Clinicians should consider testing children with ALOC for hyperammonemia, provided that a clear understanding of its metabolism and factors controlling it are understood. Proper sampling must be ensured. Mild elevations of ammonia levels are fairly common, but exceedingly high levels should raise concern and may require further evaluation
