The main aim of the study was to determine the prevalence of vascular calcifications in patients with chronic kidney disease on dialysis in our population assessed by X-ray. The secondary objectives were to determine the cardiovascular risk factors associated with the presence of vascular calcifications and to evaluate the complementary use of the echocardiogram in a cross-sectional, observational, multicentric study. We included patients with chronic kidney disease on dialysis, age =18 years with at least 3 months of renal replacement therapy in 8 dialysis centres in Argentina...

Shiga toxin (Stx)-producing Escherichia coli (STEC) infections are implicated in the development of the life-threatening hemolytic-uremic syndrome (HUS). Despite the magnitude of the social and economic problems caused by HUS, no licensed vaccine or effective therapy is currently available for human use. Prevention of STEC infections continues being the most important measure to reduce HUS incidence. This is especially true for Argentina where HUS incidence among children is extremely high and shows an endemic pattern...

There are currently two available enzyme replacement therapies for Fabry disease and little information regarding efficacy and safety of switching therapies. Between 2009 and 2012 there was a worldwide shortage of agalsidase beta and patients on that enzyme were switched to agalsidase alfa. This retrospective observational study assessed a 2-year period of efficacy and safety in a population of Fabry patients, in Argentina (30 patients) and Venezuela (3 patients), who switched therapies from algasidase beta to agalsidase alfa...

Health literacy (HL) is a measure of a patient ability to read, understand and to take decisions on medical instructions. Patients with inadequate HL have poorer health outcomes than those with adequate HL. There is little information on HL levels in diabetic patients in Argentina. The aim of this study was to explore the association between HL and glycemic control in diabetic patients from a university hospital in Argentina. HL was assessed with the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA), glycemic control through glycosylated hemoglobin A1c (HbA1c); 156 patients (58% women) took part in the study...

The expected five-year survival of chronic-phase chronic myeloid leukemia patients treated with tyrosine kinase inhibitors is over 90%. Little data is available regarding the results in the Argentinian population. This information might be of interest as generic imatinib is now available in the region. The aim of this study is to provide information on monitoring and the long-term treatment with imatinib outside of a controlled clinical trial, as well as to analyze the predictive effect of early responses to achieve molecular remission 4...

The corn leafhopper, Dalbulus maidis (DeLong), is the most important leafhopper pest of maize, Zea mays, in the Americas. A survey of the diversity of its egg parasitoids was carried out in northwestern Argentina. During summer from 2004 to 2007, the samples were collected, using sentinel eggs of D. maidis on corn leaves, exposed in 48 cornfields. Sixteen species belonging to four families of Chalcidoidea (Hymenoptera) were identified. Among the parasitoid groups, Trichogrammatidae was the most represented family with eight species, followed by Mymaridae with six species...

Soybean is an economically very important crop throughout the word and particularly in Argentina. Soybean yield may be affected by many factors such as the lack of some essential nutrients or pathogens attack. In this work we demonstrated that the co-inoculation of the native biocontrol bacterium Bacillus sp. CHEP5 which induces resistance against Cercospora sojina in soybean and the nitrogen fixing strain Bradyrhizobium japonicum E109, was more effective in reducing frog leaf spot severity than the inoculation of the biocontrol agent alone...

INTRODUCTION: Susac Syndrome is an autoimmune endotheliopathy affecting capillaries and precapillary arterioles of the brain, inner ear and retina. The classic symptom triad includes visual disturbances, hypoacusia, and encephalopathy, but is rarely fully manifest at onset. The syndrome typically follows an active fluctuating monophasic course. Typical imaging findings on brain magnetic resonance show central fiber microischemias/microinfarctions of the corpus callosum known as "snow balls", as well as lineal infarcts and upper callosal fiber involvement...

Sinotaia quadrata is a snail native from Asia recorded for the first time in South America in 2009 in central Argentina. In 2015, this species was also found in a lowland stream with different water qualities. Our aims were to contribute to the knowledge of its population ecology and to compare the individuals from the two locations anatomically. Snails were searched at 6 sites, where physicochemical and hydraulic parameters were measured. Biological samples were also taken at two sites (S3 and S4) to study the population traits of S...

Cognitive efforts tests, such as the Test of Memory Malingering (TOMM; Tombaugh, 1997), are widely used internationally, yet there is a dearth of research that has assessed the utility of these measures in different cultures, countries, and languages. This study evaluated the specificity of the TOMM Trial 2 among a sample of 3,590 Spanish-speaking adults residing in 8 Latin American countries (Argentina, Bolivia, Chile, Colombia, Mexico, Paraguay, Peru, and Puerto Rico). Trial 2 TOMM scores were negatively associated with participants' age and positively associated with level of education...

Little attention has been paid to the impact of wastewater generated by mining activities on fluoride. In this study, we evaluated the hematology responses of common South American toad Rhinella arenarum inhabiting natural and artificial environments associated with a fluorite mine from central Argentina. We analyzed three sampling stations associated with the fluorite mine: (I) Los Cerros Negros stream (CN), which runs on granitic rock with a high fluorite content; (II) Los Vallecitos stream (LV), which runs on metamorphic rock with low fluorite content; and (III) artificial decantation ponds (DP) containing sediments produced by fluorite flotation process...

Tropical forests have a high diversity of tree species which have very low densities and vary across time in their seasons of peak fruiting and maturation rates. As evidence of the ability of primates to track or anticipate changes in fruit production at individual trees, researchers have used the increased speed of primate groups toward more rewarding food patches. We analyzed the speed of approach to natural trees of wild capuchin monkeys under the effect of scramble competition, after excluding any plausible visual, olfactory and auditory cues...

Stems and leaves of Olea europaea L. (olive) avoid freezing damage by substantial supercooling during the winter season. Physiological changes during acclimation to low temperatures were studied in five olive cultivars. Water relations and hydraulic traits, ice nucleation temperature (INT) and temperatures resulting in 50% damage (LT50) were determined. All cultivars showed a gradual decrease in INT and LT50 from the dry and warm summer to the wet and cold winter in Patagonia, Argentina. During acclimation to low temperatures there was an increase in leaf cell wall rigidity and stomatal conductance (gs), as well as a decrease in leaf apoplastic water content, leaf water potential (Ψ), sap flow and stem hydraulic conductivity (ks)...

Avian influenza or bird flu is a highly contagious acute viral disease that can occur in epidemics and cross-border forms in poultry and wild birds. The characteristics of avian influenza viruses (AIVs) allow the emergence of new viral variants, some with zoonotic and pandemic potential. AIVs have been identified in Latin America; however, there is a lack of understanding of these viruses at the regional level. We performed a systematic literature review on serological or molecular evidence of AIVs circulation in Latin America...
