We previously showed that erythropoietin (EPO) attenuates the morphological signs of spinal cord ischemia/reperfusion (I/R) injury in swine [1] without, however, improving neurological function. The clinical use of EPO has been cautioned most recently due to serious safety concerns arising from an increased mortality in acute stroke patients treated with EPO and simultaneously receiving systemic thrombolysis [2]. Carbamylated EPO (cEPO) is an EPO derivative without erythropoietic activity and devoid of the EPO side eff ects, but with apparently well maintained cytoprotective qualities [3]. We therefore tested the hypothesis whether cEPO may be equally effi cient as EPO in reducing morphological as well as functional aortic occlusion-induced spinal cord I/R injury. Methods In a randomized and blinded trial pigs received either vehicle (control, n = 9), EPO or cEPO, respectively (n = 9 each; 5,000 IU/kg over 30 minutes before and during the fi rst 4 hours of reperfusion). Animals underwent 30 minutes of thoracic aortic balloon occlusion with catheters placed immediately downstream of the A. subclavia and upstream of the aortic trifurcation. Spinal cord function was assessed by motor evoked potentials (MEP as percentage of the amplitude before aortic occlusion) and lower limb refl exes (assessed as the subjective strength of response) for a period of 10 hours after reperfusion. Tissue damage was evaluated using Nissl staining. Results Both EPO-treated and cEPO-treated animals presented with attenuated spinal cord injury in the Nissl staining (median (quartile) percentage of damaged neurons in the thoracic segments: control 27 (25,44), cEPO 8 (4,10), and EPO 5 (5,7), P <0.001 vs control group; in the lumbar segments: control 26 (19,32), cEPO 7 (5,13), EPO 8 (5,10), P <0.001 vs control group). However, while only cEPO treatment was associated with recovery of the MEP amplitude to pre-occlusion values when compared with the control group (P <0.05), lower limb refl ex response was comparably restored stronger in both treatment groups (P <0.05 vs control). Conclusions In a clinically relevant porcine model mimicking aortic crossclamping during vascular surgery repair of thoracic aortic aneurysm, cEPO protected spinal cord function and integrity as eff ective as EPO when applied at equipotent doses.

Introduction In awake, spontaneously breathing mice, inhaling hydrogen sulfi de (H 2 S) induced a hibernation-like metabolic state characterised by reduced energy expenditure and hypothermia [1], which protected against otherwise lethal hypoxia [2] and hemorrhage [3] as a result of impaired cellular energy metabolism [4]. Therefore, we investigated the metabolic eff ects of inhaled H 2 S in our model of resuscitated murine septic shock. Methods Sixteen hours after induction of sepsis by cecal ligation and puncture (CLP) or sham operation, anesthetized and mechanically ventilated mice received 100 ppm H 2 S or vehicle over 5 hours at body temperatures of 38 and 27C, respectively. During the observation period, hyperdynamic hemodynamics were maintained by colloid resuscitation and noradrenaline infusion [5]. Endogenous glucose production was calculated from blood 13 C6-glucose isotope enrichment derived from the rate of appearance of stable, non-radioactive labeled 1,2,3,4,5,6-13 C6 glucose during continuous isotope infusion [6]. Whole-body glucose oxidation rate was derived from the total CO 2 -production rate, the mixed expiratory 13 CO 2 / 12 CO 2 isotope ratio and the 13 C6-glucose infusion rate after the steady state was achieved. Results While endogenous glucose production was not aff ected by hypothermia, it was signifi cantly higher in the septic animals when compared with the corresponding sham operated groups, most likely due to the ongoing noradrenaline infusion. In contrast, despite the catecholamine infusion and higher glucose release, whole body glucose oxidation was signifi cantly reduced in normothermic septic animals. During hypothermia, H 2 S shifted substrate towards preferential glucose utilisation, but this eff ect disappeared in the septic mice. Conclusions H 2 S inhalation alone does not infl uence glucose metabolism once temperature is maintained at normothermic levels in anesthetised and mechanically ventilated mice. The H 2 S-related shift of energy metabo lism towards preferential carbohydrate oxidation present during hypothermia is blunted during sepsis, possibly as a result of the ongoing catecholamine treatment.

question:
Objectives: We aimed to develop a prospective prediction tool on CrimeaneCongo haemorrhagic fever (CCHF) to identify geographic regions at risk. The tool could support public health decision-makers in implementation of an effective control strategy in a timely manner. Methods: We used monthly surveillance data between 2004 and 2015 to predict case counts between 2016 and 2017 prospectively. The Turkish nationwide surveillance data set collected by the Ministry of Health contained 10 411 confirmed CCHF cases. We collected potential explanatory covariates about climate, land use, and animal and human populations at risk to capture spatiotemporal transmission dynamics. We developed a structured Gaussian process algorithm and prospectively tested this tool predicting the future year's cases given past years' cases. Results: We predicted the annual cases in 2016 and 2017 as 438 and 341, whereas the observed cases were 432 and 343, respectively. Pearson's correlation coefficient and normalized root mean squared error values for 2016 and 2017 predictions were (0.83; 0.58) and (0.87; 0.52), respectively. The most important covariates were found to be the number of settlements with fewer than 25 000 inhabitants, latitude, longitude and potential evapotranspiration (evaporation and transpiration). Conclusions: Main driving factors of CCHF dynamics were human population at risk in rural areas, geographical dependency and climate effect on ticks. Our model was able to prospectively predict the numbers of CCHF cases. Our proof-of-concept study also provided insight for understanding possible mechanisms of infectious diseases and found important directions for practice and policy to combat against emerging infectious diseases.

question:
Although heterotypic secondary infection with dengue virus (DENV) is associated with severe disease, the majority of secondary infections are mild or asymptomatic. The mechanisms of antibody-mediated protection are poorly understood. In 2010, 108 DENV3-positive cases were enrolled in a pediatric hospital-based study in Managua, Nicaragua, with 61 primary and 47 secondary infections. We analyzed DENV-specific neutralization titers (NT 50 ), IgM and IgG avidity, and antibody titer in serum samples collected during acute and convalescent phases and 3, 6, and 18 months post-infection. NT 50 titers peaked at convalescence and decreased thereafter. IgG avidity to DENV3 significantly increased between convalescent and 3-month time-points in primary DENV infections and between the acute and convalescent phase in secondary DENV infections. While avidity to DENV2, a likely previous infecting serotype, was initially higher than avidity to DENV3 in secondary DENV infections, the opposite relation was observed 3-18 months post-infection. We found significant correlations between IgM avidity and NT 50 in acute primary cases and between IgG avidity and NT 50 in secondary DENV infections. In summary, our findings indicate that IgM antibodies likely play a role in early control of DENV infections. IgG serum avidity to DENV, analyzed for the first time in longitudinal samples, switches from targeting mainly cross-reactive serotype(s) to the current infecting serotype over time. Finally, serum avidity correlates with neutralization capacity.
