Value of the urea/creatinine index in isolated urine to estimate severe protein hypercatabolism in ventilated patients.

Objective: To study the ability of the urea/creatinine index to identify severe protein catabolism from the isolated urine of critically ventilated patients.

Methods: This was a prospective, observational study. It included 52 patients without kidney failure.

Quantification and composition analysis of plastic pollution in riverine beaches of the lower Paraná River, Argentina.

Plastic pollution and the numerous consequences it has on aquatic life have become a huge concern in recent years. While many studies have been conducted in marine environments, studies in freshwater ecosystems are scarce and insufficient. The Paraná River is the most important water course in the La Plata River basin and the fifth in the world with a mean annual discharge of 18,000 m per second.

[Relationship between the NUTRIC nutritional risk scale and protein hypercatabolism in critically ventilated patients].

Introduction: the Nutrition Risk in Critically Ill (NUTRIC) score does not include a variable that objectively estimates protein hypercatabolism (PHC), one of the main metabolic changes experienced by critical patients.

Objective: to evaluate the correlation of the NUTRIC score with PHC in critically ventilated patients.

Materials And Methods: prospective, observational study.

Postdischarge Care of Pediatric Traumatic Brain Injury in Argentina: A Multicenter Randomized Controlled Trial.

Objective: To develop, in partnership with families of children with traumatic brain injury, a postdischarge intervention that is effective, simple, and sustainable.

Design: Randomized Controlled Trial.

Setting: Seven Level 1 Pediatric Trauma Centers in Argentina.

[Study of two variants of nutritional risk score “NUTRIC” in ventilated critical patients].

Introduction: The NUTRIC score was proposed to assess the risk of adverse events potentially modifiable through nutritional intervention in critically ill patients. This score uses interleukin-6 (IL-6), a biomarker not always available.

Objective: To study two variants of the score in patients with assisted mechanical ventilation (AMV): NUTRIC-1 without IL-6 and NUTRIC-2 with CRP as biomarker.

[Usefulness of procalcitonin upon admission to intensive care in the diagnosis and prognosis of sepsis].

Objective: To assess the usefulness of procalcitonin (PCT) upon admission to the Intensive Care Unit (ICU) in the diagnosis and prognosis of sepsis

Design: A 12-month prospective observational cohort study was carried out

Setting: An 11-bed polyvalent ICU Belonging to a University hospital

Patients: Fifty patients with systemic inflammatory response syndrome (SIRS) were included. The mean age of the patients was 51.66 years, and 68% of them were males

Variables Of Interest: Upon admission, the concentration of PCT and C-reactive protein (CRP) was assessed.

Congenital Trypanosoma cruzi infection. Efficacy of its monitoring in an urban reference health center in a non-endemic area of Argentina.

Congenital transmission (CT) has acquired relevance in Chagas disease (CHD). A cohort of pregnant CHD women (4,355) and their babies were studied in the period 1994-2004. Children were excluded when they had received blood transfusions, or were born or had been in endemic areas; CT rate was 6.

Early prognosis of severe traumatic brain injury in an urban argentinian trauma center.

Background: : Previous studies indicate that age, Glasgow Coma Scale score (GCS), arterial hypotension, computed tomography (CT) findings, and pupillary reactivity are strong predictors of outcome for patients with severe traumatic brain injury (TBI). However, the predictive validity of these variables has never been rigorously tested in patients from the developing world. The objective of this study was to evaluate the prognostic value of these variables in a resource-limited setting and to test their predictive power by using them to create an outcome model.
