Changes in clinical characteristics and outcomes of patients hospitalized with COVID-19 during two years of the pandemic: experience in a venezuelan hospital.

Objectives.: To determine changes in the clinical characteristics and in-hospital outcomes of patients hospitalized for COVID-19 in a private hospital in Caracas during two years of the pandemic.

Materials And Methods.

Long-Lived Organotypic Slice Culture Model of the Rat Basolateral Amygdala.

Organotypic slice cultures (OTCs) have been employed in the laboratory since the early 1980s and have proved to be useful for the study of a number of neural systems. Our recent work focuses on the development of behavioral stress resilience induced by repeated daily injections of neuropeptide Y into the basolateral amygdala (BLA). Resilience develops over weeks, persisting to 8 weeks.

[Hepcidin as a central mediator of anemia of chronic diseases associated with obesity].

Recent evidence suggests that obesity-related inflammation may play a central role in hepcidin regulation. Hepcidin is a key regulator ofiron homeostasis and has now been suggested as a central mediator ofiron metabolism disorders involved in the pathogenesis of anemia of chronic disease. In this review, we focus on subclinical inflammation in obesity and its effect on hepcidin levels, as the most plausible explanation for the relationship between anemia of chronic disease and obesity.

Immunotherapy of american cutaneous leishmaniasis in Venezuela during the period 1990-99.

Of a total of 11532 Venezuelan patients with American cutaneous leishmaniasis (ACL) receiving immunotherapy with a combined vaccine containing heat-killed Leishmania promastigotes and bacille Calmette-Guerin (BCG) during the period 1990-99, we evaluated 5341 from 4 widely separated geographical states. Clinical healing varied from 91.2 to 98.

Latitudinal variation for two enzyme loci and an inversion polymorphism in Drosophila melanogaster from Central and South America.

Many organisms show latitudinal variation for various genetically determined traits. Such clines may involve neutral variation and originate from historical events or their maintenance may be explained by selection. For Drosophila melanogaster, latitudinal variation for allozymes, inversions, and quantitative traits has been found on several continents.

[Epidemiologic profile of transtelephonic electrocardiography in El Salvador during 1994].

Unlabelled: A total of 3,787 electrocardiograms were obtained with transtelephonic monitors (TT-ECG) during 1994 in CardioTel of Central America, Nueva San Salvador, El Salvador. Each case was evaluated in terms of patient's risk and classified as high or low risk on basis of its clinical profile. There were 3,441 traces of low risk patients and 346 of high risk one.
