[Non-caloric sweeteners consumption in the adult population of Argentina].

Introduction: Non-caloric sweeteners (NCS) are used to replace added sugars in foods and beverages. For this replacement to be a health benefit, the intake of each NCS should not exceed its Acceptable Daily Intake (ADI). The main objective of this study is to determine the consumption of aspartame, acesulfame-K, sucralose, and saccharin in the argentine population aged 15 to 65 years and to evaluate this consumption in relation to the ADI.

[Diet quality and diversity in the urban population of Argentina].

Following a varied diet is associated with a healthier diet and a greater likelihood of incorporating the necessary micronutrients. The dietary diversity index (DDI) is the indicator that measures this variety, while the diet quality index (DQI) determines how much of this diversity consists of the inclusion of healthy foods. The aim of the study was to evaluate the quality and diversity of the diet of the Argentine population by identifying differences by sex, age, socioeconomic level, nutritional status and region.

Alcohol Contribution to Total Energy Intake and Its Association with Nutritional Status and Diet Quality in Eight Latina American Countries.

Alcohol consumption is a modifiable risk factor for non-communicable diseases. This study aimed to characterize alcohol consumers at the nutritional, anthropometric, and sociodemographic levels. Data from 9218 participants from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela participating in "Latin American Health and Nutrition Study (ELANS)", a multi-country, population-based study, were used.

Socioeconomic Status Impact on Diet Quality and Body Mass Index in Eight Latin American Countries: ELANS Study Results.

Poor health and diet quality are associated with living within a low socioeconomic status (SES). This study aimed to investigate the impact of SES on diet quality and body mass index in Latin America. Data from the "Latin American Health and Nutrition Study (ELANS)", a multi-country, population-based study of 9218 participants, were used.

Dietary Diversity and Micronutrients Adequacy in Women of Childbearing Age: Results from ELANS Study.

Dietary diversity, an important component of diet quality, is associated with an increased probability of adequate micronutrient intake. Women of childbearing age (WCA) are particularly vulnerable to micronutrient inadequacy. The Minimum Dietary Diversity for Women (MDD-W) has been used widely as a proxy measurement of micronutrient adequacy.

Diet Quality and Diet Diversity in Eight Latin American Countries: Results from the Latin American Study of Nutrition and Health (ELANS).

This study aimed to assess diet quality score (DQS), considering healthy and unhealthy foods and nutrients, and diet diversity score (DDS) as indicators of risk of noncommunicable diseases in eight Latin American countries, and to verify the possible differences considering country, sex, age, socioeconomic, and nutritional status. A multicenter household population-based cross-sectional survey was conducted with 9218 individuals (age range 15-65 years). Sociodemographic and anthropometric data were collected.

Bi-Atrial Compression Due to Ascending and Descending Aortic Aneurysms.

Aortic aneurysms compressing an atrium causing symptoms are uncommon. We describe a case of bi-atrial compression due to ascending and descending aneurysms leading to dyspnea.

Left Atrial Size and Heart Failure Hospitalization in Patients with Diastolic Dysfunction and Preserved Ejection Fraction.

Context: Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome associated with diastolic function abnormalities. It remains unclear which factors, if any, can predict the transition from asymptomatic diastolic dysfunction to an overt symptomatic phase.

Materials And Methods: Patients hospitalized with suspected heart failure between January 2012 and November 2014 with a transthoracic echocardiogram demonstrating preserved systolic function were screened ( = 425).

Assessment of trans-aortic pressure gradient using a coronary pressure wire in patients with mechanical aortic and mitral valve prostheses.

Accurate evaluation of trans-aortic valvular pressure gradients is challenging in cases where dual mechanical aortic and mitral valve prostheses are present. Non-invasive Doppler echocardiographic imaging has its limitations due to multiple geometric assumptions. Invasive measurement of trans-valvular gradients with cardiac catheterization can provide further information in patients with two mechanical valves, where simultaneous pressure measurements in the left ventricle and ascending aorta must be obtained.

Bicuspid Aortic Valve and Aortic Root Morphology in Hispanic Patients.

Background: The study aim was to evaluate the aortic valve and aortic root morphology in Hispanic patients with a bicuspid aortic valve (BAV). BAV disease is one of the most common congenital anomaly of the heart, and is associated with abnormalities of the aorta. Interracial differences have been described between Caucasian and African-American patients with BAV, which may have clinical and therapeutic implications.

An example of the deleterious effects of right ventricular apical pacing.

Pacemaker implantation remains the mainstay of treatment in patients with symptomatic sinus node disease or severe heart block. Despite the dramatic benefits of this therapy, a high burden of ventricular pacing is known to have its disadvantages. Reported is the case of an 85-year-old woman with a history of sick sinus syndrome who presented with congestive heart failure after her atrioventricular sequential pacemaker defaulted to ventricular pacing mode as a result of battery depletion.

Accuracy of transthoracic echocardiography for the measurement of the ascending aorta: comparison with transesophageal echocardiography.

Background: There has been a substantial increase in the number of imaging studies performed to assess thoracic aortic pathology. We sought to determine the accuracy of transthoracic echocardiography (TTE) compared to transesophageal echocardiography (TEE) for measuring ascending aortic size.

Hypothesis: Transthoracic echocardiography is reasonably accurate for assessing ascending aortic dimension.

Interpolated premature ventricular contractions with postponed compensatory pauses: a misnomer?

Selected strips of a Holter recording obtained from a healthy young person with rare unifocal premature ventricular contractions (PVCs) were obtained. Occasionally, the PVCs were interpolated and showed the phenomenon originally named postponed compensatory pause by Langendorf [Am Heart J 1953;46:401]. But this is a misnomer because, by definition, interpolated PVCs do not have compensatory pauses.

A pulmonary embolism treated with the Angiojet technique in a patient with double outlet right ventricle.

A 24-year-old man known to have a double outlet right ventricle, status post-modified Fontan procedure at age 10, taking coumadin after having a stroke one year prior, presented with a massive pulmonary embolism and hemodynamic instability. Locally delivered tPA was unsuccessful, and the pulmonary artery thrombus was finally removed with a thrombectomy catheter (Angiojet thrombectomy); the patient recovered soon thereafter. This is the first report of the successful use of a thrombectomy catheter in a patient with pulmonary emboli and an occluded Fontan conduit.

Recording undetected P waves in a case of heart transplant with a new bipolar system.

Using a new electrocardiographic lead (L-P lead), we recorded undetected P waves in a post heart-transplant patient. This case shows another application of a noninvasive method, a modification of Einthoven's bipolar leads, used to approach undetermined rhythms.
