States Of Discontent

Latin America’s recent inclusionary turn centers on changing relationships between the popular sectors and the state. Yet the new inclusion unfolds in a region in which most states are weak and prone to severe pathologies, such as corruption, inefficiency, and particularism. The first part of the chapter outlines an argument, developed at more length elsewhere, regarding how “state crises” helped drive the consolidation of three distinct party system trajectories among the eight South American countries where the Left would eventually win power. The second part of the chapter argues that these trajectories differed in three ways that likely conditioned how the concomitant inclusionary Left turn unfolded in each case: the institutionalization of left-wing parties, the occurrence of state transformation via constitutional reform, and the level of state capacity. The discussion helps highlight the central role of the state and its pathologies in both driving alternative paths of political development and in conditioning the politics of inclusion. By putting the emphasis on the state and its pathologies, we can better consider not just the sources of sociopolitical exclusion but also the limits of sociopolitical inclusion

Nrf2-interacting nutrients and COVID-19 : time for research to develop adaptation strategies

There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR gamma:Peroxisome proliferator-activated receptor, NF kappa B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2 alpha:Elongation initiation factor 2 alpha). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT(1)R axis (AT(1)R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity

Cabbage and fermented vegetables : From death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19

Large differences in COVID-19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS-CoV-2 binds to its receptor, the angiotensin-converting enzyme 2 (ACE2). As a result of SARS-CoV-2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT(1)R) axis associated with oxidative stress. This leads to insulin resistance as well as lung and endothelial damage, two severe outcomes of COVID-19. The nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the most potent antioxidant in humans and can block in particular the AT(1)R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are: kimchi in Korea, westernized foods, and the slum paradox. It is proposed that fermented cabbage is a proof-of-concept of dietary manipulations that may enhance Nrf2-associated antioxidant effects, helpful in mitigating COVID-19 severity.Peer reviewe

Is diet partly responsible for differences in COVID-19 death rates between and within countries?

Correction: Volume: 10 Issue: 1 Article Number: 44 DOI: 10.1186/s13601-020-00351-w Published: OCT 26 2020Reported COVID-19 deaths in Germany are relatively low as compared to many European countries. Among the several explanations proposed, an early and large testing of the population was put forward. Most current debates on COVID-19 focus on the differences among countries, but little attention has been given to regional differences and diet. The low-death rate European countries (e.g. Austria, Baltic States, Czech Republic, Finland, Norway, Poland, Slovakia) have used different quarantine and/or confinement times and methods and none have performed as many early tests as Germany. Among other factors that may be significant are the dietary habits. It seems that some foods largely used in these countries may reduce angiotensin-converting enzyme activity or are anti-oxidants. Among the many possible areas of research, it might be important to understand diet and angiotensin-converting enzyme-2 (ACE2) levels in populations with different COVID-19 death rates since dietary interventions may be of great benefit.Peer reviewe

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Paleoenvironmental reconstruction of a Late Quaternary lagoon system in southern Brazil (Jaguaruna region, Santa Catarina state) based on multi-proxy analysis

This paper provides a paleoenvironmental reconstruction of a Late Quaternary lagoon system in the Jaguaruna region of Santa Catarina state, southern Brazil. Integrated results of bulk sedimentary organic matter characterization (delta C-13, delta N-15 and C/N), microfossil (pollen and diatom) and grain-size analysis from three shallow cores (similar to 2.5m depth) allowed us to propose an evolving paleogeographic scenario in this coastal region for the last ca. 5500 cal a BP. The lagoonal system in this area was more extensive during the mid-Holocene than today, with a gradual and continuous lagoon-sea disconnection until the present. We add to the debate regarding relative sea-level (RSL) variations for the Brazilian coast during the Holocene and discuss the importance of sedimentary dynamics for interpreting changes in coastal ecosystems. The multi-proxy analysis suggests that changes in coastal ecosystems could be directly related to local sedimentary processes, which are not necessarily linked to RSL fluctuations and/or to climatic variations.

The malnutrition and inflammation axis in pediatric patients with chronic kidney disease

Malnutrition and inflammation are closely linked in adult chronic kidney disease (CKD) patients and are both related to poor outcome, but data on pediatric patients are lacking. To describe the prevalence of inflammation, evaluate nutritional status, their correlation to each other, and their possible determinants in pediatric patients with CKD in predialysis, on hemodialysis (HD), and peritoneal dialysis (PD) who were submitted to demographic, nutritional, and inflammatory evaluations. Patients' nutritional status was evaluated according to anthropometric parameters and body composition assessed by measurements of skinfold thickness and bioelectrical impedance. Inflammation was assessed by measurement of highly sensitive C-reactive protein (CRP), ferritin, and albumin. Patients with CRP > 1 mg/l were considered inflamed. Sixty-four pediatric patients (mean age 9 +/- 4 years-, 40% on HD, 22% on PD, and 38% predialysis) were studied. Mean CRP concentration was 3.+/- 6.5 mg/l (median 0.78 mg/l, range 0.78-33.4 mg/l), and 41% presented CRP levels above 1 mg/l. Mean ferritin was 148 +/- 197 mg/dl and was above the normal reference values in 28% of patients. On the other hand, mean albumin was 3.9 +/- 0.5 mg/dl, below reference value in only 13% of patients. A larger proportion of HD patients (52%) were inflamed compared with those on PD (31%; p < 0.05). Malnutrition prevalence varied from 5% to 65% according to the method used. While inflamed patients presented lower serum bicarbonate and were on HD for a longer time, there were no consistent associations between malnutrition and inflammation. Inflammation is highly prevalent in the pediatric CKD population and was not consistently related to malnutrition. Other risk factors linked to high mortality and morbidity (acidosis and longer time on dialysis) were associated with inflammation. Prospective studies will need to analyze the predictive value of inflammation and malnutrition markers in the pediatric CKD population.Pontificia Univ Catolica Parana, Ctr Hlth & Biol Sci, BR-80215901 Curitiba, Parana, BrazilHosp Infantil Pequeno Principe, Curitiba, Parana, BrazilUniversidade Federal de São Paulo, EPM, CAAA, Dept Pediat, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, Hosp Rime Hipertensao, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, CAAA, Dept Pediat, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, Hosp Rime Hipertensao, São Paulo, BrazilWeb of Scienc
