Income distribution in the Latin American Southern Cone during the first globalization boom, ca: 1870-1920
Latin America is the most unequal region in the world and there is a lively
debate concerning the explanations and timing of such high levels of income
inequality. Latin America was also the region, not including European Offshoots,
which experienced the most rapid growth during the first globalization boom. It
can, therefore, be taken as an interesting case study for how globalization
forces impinged on growth and income distribution in peripheral regions. This
paper presents a first estimate of income inequality in the Southern Cone of
South America (Brazil 1872 and 1920, Chile 1870 and 1920, Uruguay 1920)
and some assumptions concerning Argentina (1870 and 1920), and Uruguay
(1870). We find an increasing inequality trend between 1870 and 1920 which
can be explained as a process of inequality both within individual countries and
between countries. This trend is discussed along three lines: the relation
between inequality and per capita income levels; the dynamics of the expansion
to new areas, and movements of relative factor prices and of the terms of trade

Between the colonial heritage and the first globalization boom: on income inequality in the Southern Cone
Special Issue on Latin American Inequality.This paper presents a first estimate of income inequality in the Southern Cone of South America (Brazil 1872 and 1920, Chile 1870 and 1920, Uruguay 1920) and some assumptions with regard to Argentina (1870 and 1920) and Uruguay (1870). We find that income distribution was relatively high on the eve of the first globalization boom. Thus, inequality is not only the result of globalization, but also a structural feature. Inequality increased between 1870 and 1920, both within individual countries and between countries. Globalization forces do not result in obvious outcomes. Rather, the effect of globalization on inequality depends on the expansion of the frontier and institutional persistence and change in old and new areas. Inequality was clearly high in the wake of the globalization process. This was a particular kind of inequality, which was part of a set of institutions closely linked to the exports of primary goods, sluggish technological change and limited human capital formation.Este artículo presenta una primera estimación de la distribución del ingreso en el Cono Sur de Sudamérica (Brasil 1872 y 1920, Chile 1870 y 1920, Uruguay 1920) y algunos supuestos sobre la desigualdad en Argentina 1870 y 1920, así como en Uruguay en 1870. Encontramos que la distribución del ingreso era relativamente alta en los albores de la primera globalización, por lo que la desigualdad del ingreso no solamente debe ser vista como el resultado de la globalización, sino como una característica estructural. La desigualdad aumentó entre 1870 y 1920, tanto dentro de cada país como entre los países del Cono Sur. Las fuerzas de la globalización no generan resultados obvios. Por el contrario, el impacto de la globalización sobre la desigualdad depende de la expansión de la frontera y de la persistencia y el cambio institucional en las viejas áreas y en las nuevas. La desigualdad fue particularmente alta al culminar la globalización. Se trató de una forma particular de desigualdad, que formó parte de un conjunto de instituciones estrechamente vinculadas a una economía exportadora de bienes primarios, con escaso desarrollo tecnológico y bajos niveles de formación de capital humano.This paper was written as part of the project «A Global History of Inequality in the Long 20th Century», directed by Luis Bértola and financed by CSIC, Universidad de la República, Uruguay
COVID-19 in rheumatic diseases in Italy: first results from the Italian registry of the Italian Society for Rheumatology (CONTROL-19)
OBJECTIVES:
Italy was one of the first countries significantly affected by the coronavirus disease 2019 (COVID-19) epidemic. The Italian Society for Rheumatology promptly launched a retrospective and anonymised data collection to monitor COVID-19 in patients with rheumatic and musculoskeletal diseases (RMDs), the CONTROL-19 surveillance database, which is part of the COVID-19 Global Rheumatology Alliance.
METHODS:
CONTROL-19 includes patients with RMDs and proven severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) updated until May 3rd 2020. In this analysis, only molecular diagnoses were included. The data collection covered demographic data, medical history (general and RMD-related), treatments and COVID-19 related features, treatments, and outcome. In this paper, we report the first descriptive data from the CONTROL-19 registry.
RESULTS:
The population of the first 232 patients (36% males) consisted mainly of elderly patients (mean age 62.2 years), who used corticosteroids (51.7%), and suffered from multi-morbidity (median comorbidities 2). Rheumatoid arthritis was the most frequent disease (34.1%), followed by spondyloarthritis (26.3%), connective tissue disease (21.1%) and vasculitis (11.2%). Most cases had an active disease (69.4%). Clinical presentation of COVID-19 was typical, with systemic symptoms (fever and asthenia) and respiratory symptoms. The overall outcome was severe, with high frequencies of hospitalisation (69.8%), respiratory support oxygen (55.7%), non-invasive ventilation (20.9%) or mechanical ventilation (7.5%), and 19% of deaths. Male patients typically manifested a worse prognosis. Immunomodulatory treatments were not significantly associated with an increased risk of intensive care unit admission/mechanical ventilation/death.
CONCLUSIONS:
Although the report mainly includes the most severe cases, its temporal and spatial trend supports the validity of the national surveillance system. More complete data are being acquired in order to both test the hypothesis that RMD patients may have a different outcome from that of the general population and determine the safety of immunomodulatory treatments
Proof-of-concept evidence for high-density EEG investigation of sleep slow wave traveling in First-Episode Psychosis.
Schizophrenia is thought to reflect aberrant connectivity within cortico-cortical and reentrant thalamo-cortical loops, which physiologically integrate and coordinate the function of multiple cortical and subcortical structures. Despite extensive research, reliable biomarkers of such "dys-connectivity" remain to be identified at the onset of psychosis, and before exposure to antipsychotic drugs. Because slow waves travel across the brain during sleep, they represent an ideal paradigm to study pathological conditions affecting brain connectivity. Here, we provide proof-of-concept evidence for a novel approach to investigate slow wave traveling properties in First-Episode Psychosis (FEP) with high-density electroencephalography (EEG). Whole-night sleep recordings of 5 drug-naïve FEP and 5 age- and gender-matched healthy control subjects were obtained with a 256-channel EEG system. One patient was re-recorded after 6 months and 3 years of continuous clozapine treatment. Slow wave detection and traveling properties were obtained with an open-source toolbox. Slow wave density and slow wave traveled distance (measured as the line of longest displacement) were significantly lower in patients (p < 0.05). In the patient who was tested longitudinally during effective clozapine treatment, slow wave density normalized, while traveling distance only partially recovered. These preliminary findings suggest that slow wave traveling could be employed in larger samples to detect cortical "dys-connectivity" at psychosis onset
Evaluation of CSF1R ‐related adult onset leukoencephalopathy with axonal spheroids and pigmented glia diagnostic criteria
Background and purpose: Diagnostic criteria for adult onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) due to colony-stimulating factor 1 receptor (CSF1R) mutation have recently been proposed. Our objective was to assess their accuracy in an independent multicenter cohort.Methods: We evaluated the sensitivity and specificity of the diagnostic criteria for ALSP (including the "probable" and "possible" definitions) in a national cohort of 22 patients with CSF1R mutation, and 59 patients with an alternative diagnosis of adult onset inherited leukoencephalopathy.Results: Overall, the sensitivity of the diagnostic criteria for ALSP was 82%, including nine of 22 patients diagnosed as probable and nine of 22 diagnosed as possible. Twenty of the 59 CSF1R mutation-negative leukoencephalopathies fulfilled the diagnostic criteria, leading to a specificity of 66%.Conclusions: Diagnostic criteria for ALSP have an overall limited sensitivity along with a modest specificity. We suggest that in patients suspected of genetic leukoencephalopathy, a comprehensive magnetic resonance imaging pattern-based approach is warranted, together with white matter gene panel or whole exome sequencing
Plasma oxysterols: biomarkers for diagnosis and treatment in spastic paraplegia type 5
IF 10.292International audienceThe hereditary spastic paraplegias are an expanding and heterogeneous group of disorders characterized by spasticity in the lower limbs. Plasma biomarkers are needed to guide the genetic testing of spastic paraplegia. Spastic paraplegia type 5 (SPG5) is an autosomal recessive spastic paraplegia due to mutations in CYP7B1, which encodes a cytochrome P450 7α-hydroxylase implicated in cholesterol and bile acids metabolism. We developed a method based on ultra-performance liquid chromatography electrospray tandem mass spectrometry to validate two plasma 25-hydroxycholesterol (25-OHC) and 27-hydroxycholesterol (27-OHC) as diagnostic biomarkers in a cohort of 21 patients with SPG5. For 14 patients, SPG5 was initially suspected on the basis of genetic analysis, and then confirmed by increased plasma 25-OHC, 27-OHC and their ratio to total cholesterol. For seven patients, the diagnosis was initially based on elevated plasma oxysterol levels and confirmed by the identification of two causal CYP7B1 mutations. The receiver operating characteristic curves analysis showed that 25-OHC, 27-OHC and their ratio to total cholesterol discriminated between SPG5 patients and healthy controls with 100% sensitivity and specificity. Taking advantage of the robustness of these plasma oxysterols, we then conducted a phase II therapeutic trial in 12 patients and tested whether candidate molecules (atorvastatin, chenodeoxycholic acid and resveratrol) can lower plasma oxysterols and improve bile acids profile. The trial consisted of a three-period, three-treatment crossover study and the six different sequences of three treatments were randomized. Using a linear mixed effect regression model with a random intercept, we observed that atorvastatin decreased moderately plasma 27-OHC (∼30%, P < 0.001) but did not change 27-OHC to total cholesterol ratio or 25-OHC levels. We also found an abnormal bile acids profile in SPG5 patients, with significantly decreased total serum bile acids associated with a relative decrease of ursodeoxycholic and lithocholic acids compared to deoxycholic acid. Treatment with chenodeoxycholic acid restored bile acids profile in SPG5 patients. Therefore, the combination of atorvastatin and chenodeoxycholic acid may be worth considering for the treatment of SPG5 patients but the neurological benefit of these metabolic interventions remains to be evaluated in phase III therapeutic trials using clinical, imaging and/or electrophysiological outcome measures with sufficient effect sizes. Overall, our study indicates that plasma 25-OHC and 27-OHC are robust diagnostic biomarkers of SPG5 and shall be used as first-line investigations in any patient with unexplained spastic paraplegia
