33. Relationship of relevant factors to P(v-a)CO2/C(a-v)O-2 ratio in critically ill patients

Abstract

Objective This study investigated the factors related to the ratio of the venoarterial carbon dioxide tension difference [P(v-a)CO2] to the arteriovenous oxygen content difference [C(a-v)O2] (hereafter termed “Ratio”). Methods We retrospectively studied 1294 pairs of arterial and central venous blood gas measurements in 352 critically ill patients. A high Ratio was defined as > 1.68 based on published literature. Measurements were divided into four groups: Group I [P(v-a)CO2 ≤ 6 mmHg/central venous oxygen saturation (ScvO2) < 70%], Group II [P(v-a)CO2 ≤ 6 mmHg/ScvO2 ≥ 70%], Group III [P(v-a)CO2 > 6 mmHg/ScvO2 ≥ 70%], and Group IV [P(v-a)CO2 > 6 mmHg/ScvO2 < 70%]. Results The Ratio’s strongest correlation was with P(v-a)CO2 when compared with ScvO2 and hemoglobin in all data. The P(v-a)CO2 and ScvO2 were significantly higher and the hemoglobin and arterial oxygen saturation were significantly lower in the high Ratio measurements (>1.68) than low Ratio measurements (≤1.68). The P(v-a)CO2 was best for predicting a high Ratio. A P(v-a)CO2 threshold of 7 mmHg was associated with a sensitivity of 41.77% and specificity of 90.62% for predicting a high Ratio. Conclusions A high P(v-a)CO2 is the most relevant contributor to a high Ratio among all related factors in critically ill patients.

34. Resuscitation incoherence and dynamic circulation-perfusion coupling in circulatory shock

Author

Abstract

Objective: Poor tissue perfusion/cellular hypoxia may persist despite restoration of the macrocirculation (Macro). This article reviewed the literatures of coherence between hemodynamics and tissue perfusion in circulatory shock. Data sources: We retrieved information from the PubMed database up to January 2018 using various search terms or/and their combinations, including resuscitation, circulatory shock, septic shock, tissue perfusion, hemodynamic coherence, and microcirculation (Micro). Study selection: The data from peer-reviewed journals printed in English on the relationships of tissue perfusion, shock, and resuscitation were included. Results: A binary (coherence/incoherence, coupled/uncoupled, or associated/disassociated) mode is used to describe resuscitation coherence. The phenomenon of resuscitation incoherence (RI) has gained great attention. However, the RI concept requires a more practical, systematic, and comprehensive framework for use in clinical practice. Moreover, we introduce a conceptual framework of RI to evaluate the interrelationship of the Macro, Micro, and cell. The RI is divided into four types (Type 1: Macro-Micro incoherence + impaired cell; Type 2: Macro-Micro incoherence + normal cell; Type 3: Micro-Cell incoherence + normal Micro; and Type 4: both Macro-Micro and Micro-cell incoherence). Furthermore, we propose the concept of dynamic circulation-perfusion coupling to evaluate the relationship of circulation and tissue perfusion during circulatory shock. Conclusions: The concept of RI and dynamic circulation-perfusion coupling should be considered in the management of circulatory shock. Moreover, these concepts require further studies in clinical practice.

Abstract

Photoluminescence measurements were used to investigate the optical characteristics of high density two-dimensional electron gas in GaAs/Al0.3Ga0.7As modulation-doped quantum wells. The results showed that current thinking regarding the transition between the second conduction subband and the ground-state heavy-hole subband was erroneous as there was no large breakdown of the parity selection rule of the optical matrix element in quantum wells.

Abstract

International audience; Atomic masses of seven Tz=−1, fp-shell nuclei from V44 to Cu56 and two low-lying isomers, V44m (Jπ=6+) and Co52m (Jπ=2+), have been measured with relative precisions of 1–4×10−7 with isochronous mass spectrometry (IMS) at the Cooler Storage Ring (CSRe), Lanzhou. The masses of Cu56, Co52g,52m, and V44m were measured for the first time in this experiment. The mass excesses (ME"s) of V44, Mn48, Fe50, and Ni54 are determined with an order of magnitude improved precision compared to the literature values. Co52g,52m and Cu56 are found to be 370 and 400 keV more bound, respectively, while V44g,44m are ∼300 keV less bound than the extrapolations in the Atomic-Mass Evaluation 2012 (AME"12). The masses of the four Tz=−1/2 nuclei V45, Cr47, Mn49, and Fe51 are re-determined to be in agreement, within the experimental errors, with the recent JYFLTRAP (University of Jyväskylä, Finland) measurements or with the previous IMS measurements in CSRe. Details of the measurements and data analysis are described, and the impact of the new ME values on different aspects in nuclear structure are investigated and discussed.

Abstract

A new measurement of the reactor antineutrino flux and energy spectrum by the Daya Bay reactor neutrino experiment is reported. The antineutrinos were generated by six 2.9 GWth nuclear reactors and detected by eight antineutrino detectors deployed in two near (560 m and 600 m flux-weighted baselines) and one far (1640 m flux-weighted baseline) underground experimental halls. With 621 days of data, more than 1.2 million inverse beta decay (IBD) candidates were detected. The IBD yield in the eight detectors was measured, and the ratio of measured to predicted flux was found to be 0.946±0.020 (0.992±0.021) for the Huber+Mueller (ILL+Vogel) model. A 2.9σ deviation was found in the measured IBD positron energy spectrum compared to the predictions. In particular, an excess of events in the region of 4–6 MeV was found in the measured spectrum, with a local significance of 4.4σ. A reactor antineutrino spectrum weighted by the IBD cross section is extracted for model-independent predictions.
