The Inclusive Growth and Development Report 2017
Around the globe, leaders of governments and other stakeholder institutions enter 2017 facing a set of difficult and increasingly urgent questions:With fiscal space limited, interest rates near zero, and demographic trends unfavorable in many countries, does the world economy face a protracted period of relatively low growth? Will macroeconomics and demography determine the world economy's destiny for the foreseeable future?Can rising in-country inequality be satisfactorily redressed within the prevailing liberal international economic order? Can those who argue that modern capitalist economies face inherent limitations in this regard – that their internal "income distribution system" is broken and likely beyond repair – be proven wrong?As technological disruption accelerates in the Fourth Industrial Revolution, how can societies organize themselves better to respond to the potential employment and other distributional effects? Are expanded transfer payments the only or primary solution, or can market mechanisms be developed to widen social participation in new forms of economic value-creation?These questions beg the more fundamental one of whether a secular correction is required in the existing economic growth model in order to counteract secular stagnation and dispersion (chronic low growth and rising inequality). Does the mental map of how policymakers conceptualize and enable national economic performance need to be redrawn? Is there a structural way, beyond the temporary monetary and fiscal measures of recent years, to cut the Gordian knot of slow growth and rising inequality, to turn the current vicious cycle of stagnation and dispersion into a virtuous one in which greater social inclusion and stronger and more sustainable growth reinforce each other?This is precisely what government, business, and other leaders from every region have been calling for. Over the past several years, a worldwide consensus has emerged on the need for a more inclusive growth and development model; however, this consensus is mainly directional. Inclusive growth remains more a discussion topic than an action agenda. This Report seeks to help countries and the wider international community practice inclusive growth and development by offering a new policy framework and corresponding set of policy and performance indicators for this purpose
Successful Use of Extracorporeal Life Support after Double Traumatic Tracheobronchial Injury in a Patient with Severe Acute Asthma
We report the case of an asthmatic patient with blunt trachea and left main bronchus injuries who developed acute severe asthma after surgical repair. Despite medical treatment and ventilatory support, asthma persisted with high airway pressures and severe respiratory acidosis. We proposed venovenous extracorporeal life support for CO2 removal which allowed arterial blood gas normalization and airway pressures decrease. Extracorporeal life support was removed on day five after medical treatment of acute severe asthma. So we report the successful use of extracorporeal life support for operated double blunt tracheobronchial injury with acute severe asthma
Overview of adverse events related to invasive procedures in the intensive care unit
BackgroundThis study was conducted to determine the frequency, predictors, and clinical impact of adverse events (AEs) related to invasive procedures in the intensive care unit (ICU). Methods This was a prospective observational study of ICUs in a university hospital. Results A total of 893 patients requiring invasive procedures were admitted over a 1-year period. Among these, 310 patients (34.7%) experienced a total of 505 AEs. The mean number of AEs per patient was 1.6 ± 1.1 (range, 1-7). Infectious AEs were significantly more frequent than mechanical AEs (60.4% vs 39.6%; P = .01). Factors independently associated with AE occurrence were isolation of multidrug-resistant bacteria at ICU admission, >5 invasive procedures, and ICU length of stay >8 days. Thirty-three AEs (6.5%) resulted in severe clinical impact, including 24 deaths. Ventilator-associated pneumonia (VAP) accounted for 62.5% of the deaths related to AEs. Conclusions One-third of critically ill patients experienced AEs related to invasive procedures. Severe AEs were associated with 11% of all ICU deaths. VAP was the most frequent AE related to death. An improved assessment of the risk–benefit balance before each invasive procedure and increased efforts to decrease VAP prevalence are needed to reduce AE-related mortality

Bradykinin and adenosine receptors mediate desflurane induced postconditioning in human myocardium: role of reactive oxygen species
BACKGROUND:
Desflurane during early reperfusion has been shown to postcondition human myocardium, in vitro. We investigated the role of adenosine and bradykinin receptors, and generation of radical oxygen species in desflurane-induced postconditioning in human myocardium.
METHODS:
We recorded isometric contraction of human right atrial trabeculae hanged in an oxygenated Tyrode's solution (34 degrees Celsius, stimulation frequency 1 Hz). After a 30-min hypoxic period, desflurane 6% was administered during the first 5 min of reoxygenation. Desflurane was administered alone or with pretreatment of N-mercaptopropionylglycine, a reactive oxygen species scavenger, 8-(p-Sulfophenyl)theophylline, an adenosine receptor antagonist, HOE140, a selective B2 bradykinin receptor antagonist. In separate groups, adenosine and bradykinin were administered during the first minutes of reoxygenation alone or in presence of N-mercaptopropionylglycine. The force of contraction of trabeculae was recorded continuously. Developed force at the end of a 60-min reoxygenation period was compared (mean +/- standard deviation) between the groups by a variance analysis and post hoc test.
RESULTS:
Desflurane 6% (84 +/- 6% of baseline) enhanced the recovery of force after 60-min of reoxygenation as compared to control group (51 +/- 8% of baseline, P < 0.0001). N-mercaptopropionylglycine (54 +/- 3% of baseline), 8-(p-Sulfophenyl)theophylline (62 +/- 9% of baseline), HOE140 (58 +/- 6% of baseline) abolished desflurane-induced postconditioning. Adenosine (80 +/- 9% of baseline) and bradykinin (83 +/- 4% of baseline) induced postconditioning (P < 0.0001 vs control), N-mercaptopropionylglycine abolished the beneficial effects of adenosine and bradykinin (54 +/- 8 and 58 +/- 5% of baseline, respectively).
CONCLUSIONS:
In vitro, desflurane-induced postconditioning depends on reactive oxygen species production, activation of adenosine and bradykinin B2 receptors. And, the cardioprotective effect of adenosine and bradykinin administered at the beginning of reoxygenation, was mediated, at least in part, through ROS production
Hemispheric reconfigurations in Northern Amazonia: The ‘Three Guianas’ amid regional change and Brazilian hegemony
© 2016 Southseries Inc., www.thirdworldquarterly.com. Regional and hemispheric reconfigurations in Latin America and the Caribbean are increasingly mediated by Brazilian power, and the engagement of Guyana, Suriname and French Guiana with this emerging context is intriguing. They are tentatively moving away from a Caribbean region with which they are culturally contiguous, towards a South American continent in which they are geographically located. This is partly a reflection of the gradual opening up of the Northern Amazonian space that they share collectively, and also with Venezuela and Brazil. These processes are occurring as cause and effect of Brazil’s emergence as a regional–and even regionally hegemonic–power. With reference to wider debates on regionalism and hegemony, we analyse the uncertain consequences of these shifts
The “Goldilocks Zoneâ€? from a redox perspectiveâ€â€�Adaptive vs. deleterious responses to oxidative stress in striated muscle
Consequences of oxidative stress may be beneficial or detrimental in physiological systems. An organ system's position on the “hormetic curve� is governed by the source and temporality of reactive oxygen species (ROS) production, proximity of ROS to moieties most susceptible to damage, and the capacity of the endogenous cellular ROS scavenging mechanisms. Most importantly, the resilience of the tissue (the capacity to recover from damage) is a decisive factor, and this is reflected in the disparate response to ROS in cardiac and skeletal muscle. In myocytes, a high oxidative capacity invariably results in a significant ROS burden which in homeostasis, is rapidly neutralized by the robust antioxidant network. The up-regulation of key pathways in the antioxidant network is a central component of the hormetic response to ROS. Despite such adaptations, persistent oxidative stress over an extended time-frame (e.g., months to years) inevitably leads to cumulative damages, maladaptation and ultimately the pathogenesis of chronic diseases. Indeed, persistent oxidative stress in heart and skeletal muscle has been repeatedly demonstrated to have causal roles in the etiology of heart disease and insulin resistance, respectively. Deciphering the mechanisms that underlie the divergence between adaptive and maladaptive responses to oxidative stress remains an active area of research for basic scientists and clinicians alike, as this would undoubtedly lead to novel therapeutic approaches. Here, we provide an overview of major types of ROS in striated muscle and the divergent adaptations that occur in response to them. Emphasis is placed on highlighting newly uncovered areas of research on this topic, with particular focus on the mitochondria, and the diverging roles that ROS play in muscle health (e.g., exercise or preconditioning) and disease (e.g., cardiomyopathy, ischemia, metabolic syndrome)
