Speckle tracking echocardiography in the indeterminate form of Chagas disease.

Background: Chagas disease is one of the most common diseases in Latin-America, and cardiac involvement is a significant cause of death. Assessment of myocardial strain may detect early myocardial damage.

Objectives: To determine differences in longitudinal strain using speckle tracking to assess regional and global left ventricular function in patients with the indeterminate form of Chagas disease, in comparison with a control group.

Evaluation of the nutritional quality of the grain protein of new amaranths varieties.

The efforts for promoting the consumption of food of plant origin are increasingly growing. The amaranth grain is an important vegetable protein source, superior in content and quality to traditional cereals. In the central-west region of Argentina, new amaranth varieties have been obtained to optimize its agronomic traits and promote its use.

The cost of generalized anxiety disorder in primary care settings: results of the ANCORA study.

To assess the cost of illness of generalized anxiety disorder (GAD) in a primary healthcare setting in Spain. A cross-sectional, retrospective study was conducted. The sample comprised patients diagnosed with GAD according to ICD-10 criteria and a control group.

[Economic and epidemiologic aspects of generalized anxiety disorder: a review of the literature].

Introduction: The objective is to assess the prevalence and treatment patterns of generalized anxiety disorder (GAD) in Spain as well as the cost associated to this disorder in different countries.

Methods: A search in the literature of health and economics databases was conducted.

Results: In regards to the 32 references selected, 6 studies had data on the prevalence of GAD and 3 on treatment patterns in Spain and 11 studies on the costs associated to the disease on an international level.

[Retroperitoneal fibromatosis: report of a case].

We report a 42 years old female that presented with abdominal pain and no palpable mass. Imaging abdominal ultrasound, CAT scan and magnetic resonance showed a solid tumor located in the retroperitoneum. The patient was operated on excising the tumor.

Nutrient and antinutrient composition of Amaranthus muricatus.

The chemical and nutritional composition of the aerial parts of Amaranthus muricatus was assessed. This is a wild plant growing well in arid and poor soil, which are not suitable for cereals. The material under study was boiled, dried and ground and then evaluated for chemical, nutritional and antinutritional properties.

[Chemical composition of 2 wild vegetable species compared with chard].

The nutritional quality of two wild vegetable species, Kochia scoparia (Ks) and Chenopodium album (Cha) was evaluated and compared with Beta vulgaris var. cicla(chard) (Bv), in order to propose their domestication as alternative protein sources. Chemical percentual analysis (AOAC), gaseous chromatography fatty acid determination, and antinutrient searching (by chemical, enzymatic and immunological method) were performed.
