Assessment of the shock index in septic shock: A systematic review.

Objective: To identify published research on the Shock Index (SI) in patients with septic shock or severe sepsis and to describe its main findings and conclusions.

Design: Systematic review of the literature following the recommendations of the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).

Settings: The following databases were consulted: Pubmed, Embase, Library Cochrane and Lilacs.

Predictive value of dynamic arterial elastance for vasopressor withdrawal: a systematic review and meta-analysis.

Background: Dynamic arterial elastance (Ea) has been investigated for its ability to predict hypotension during the weaning of vasopressors. Our study focused on assessing Ea's performance in the context of critically ill adult patients admitted to the intensive care unit, regardless of diagnosis.

Main Body: Our study was conducted in accordance with the Preferred Reported Items for Systematic Reviews and Meta-Analysis checklist.

[Adherence to the Clinical Practice Guidelines for the hospital management of patients with decompensated heart failure in a Coronary Care Unit in Colombia].

Objective: To assess adherence to the recommendations for the diagnosis and management of hospitalized patients with Decompensated Heart Failure issued by the European Society of Cardiology in 2021 at a Coronary Care Unit at a fourth-level hospital in the city of Bogotá.

Materials And Methods: A descriptive cross-sectional study was conducted, including hospitalized patients in the Coronary Care Unit at Hospital San José in Bogotá, with a primary diagnosis of Decompensated Heart Failure, from September 2021 to January 2023. Patient data were collected from medical records.

Variables influencing the prediction of fluid responsiveness: a systematic review and meta-analysis.

Introduction: Prediction of fluid responsiveness in acutely ill patients might be influenced by a number of clinical and technical factors. We aim to identify variables potentially modifying the operative performance of fluid responsiveness predictors commonly used in clinical practice.

Methods: A sensitive strategy was conducted in the Medline and Embase databases to search for prospective studies assessing the operative performance of pulse pressure variation, stroke volume variation, passive leg raising (PLR), end-expiratory occlusion test (EEOT), mini-fluid challenge, and tidal volume challenge to predict fluid responsiveness in critically ill and acutely ill surgical patients published between January 1999 and February 2023.

UNVEILING THE SIGNIFICANCE OF DYNAMIC ARTERIAL ELASTANCE: AN INSIGHTFUL APPROACH TO ASSESSING ARTERIAL LOAD IN AN ENDOTOXIN SHOCK MODEL.

Background: The aim of this study was to investigate the relationship between dynamic arterial elastance (EaDyn) and the pulsatile and steady components of arterial load in an endotoxin shock model using a two-element Windkessel model and to describe the behavior of EaDyn in this model. Methods : Ten female Yorkshire pigs were administered lipopolysaccharide intravenously to induce endotoxin shock, while three female pigs served as the control group. Measurements of EaDyn (ratio between pulse pressure variation and stroke volume variation), effective arterial elastance, arterial compliance (Cart), and systemic vascular resistance were taken every 30 min in the endotoxin group until shock was induced.

Obesity and the obesity paradox in patients with severe COVID-19.

Objective: To test the presence of the obesity paradox in two cohorts of patients hospitalized for COVID-19.

Design: Two multicenter prospective cohorts.

Setting: Three fourth level institutions.

Changes of operative performance of pulse pressure variation as a predictor of fluid responsiveness in endotoxin shock.

Several limitations regarding pulse pressure variation (PPV) use have been reported. Our aim was to describe changes in the PPV operative performance as a predictor of fluid responsiveness during the development of a swine endotoxin shock model and to assess hemodynamic variables associated with PPV changes. A swine porcine endotoxin shock model was established (Escherichia Coli 055:B5 endotoxin) in 7 pigs, and 3 pigs were included in the control group.

Predictors of fluid responsiveness in critically ill patients mechanically ventilated at low tidal volumes: systematic review and meta-analysis.

Introduction: Dynamic predictors of fluid responsiveness have shown good performance in mechanically ventilated patients at tidal volumes (Vt) > 8 mL kg. Nevertheless, most critically ill conditions demand lower Vt. We sought to evaluate the operative performance of several predictors of fluid responsiveness at Vt ≤ 8 mL kg by using meta-regression and subgroup analyses.

Use of Pulse Pressure Variation as Predictor of Fluid Responsiveness in Patients Ventilated With Low Tidal Volume: A Systematic Review and Meta-Analysis.

Introduction: Pulse pressure variation (PPV) has been shown to be useful to predict fluid responsiveness in patients ventilated at tidal volume (Vt) >8 mL kg. Nevertheless, most conditions in critical care force to use lower Vt. Thus, we sought to evaluate the operative performance of PPV when a Vt ⩽8 mL kg is used during mechanical ventilation support.

Effectiveness of a case management model for the comprehensive provision of health services to multi-pathological people.

Aim: To determine the effectiveness of a case management model for approaching multi-pathological people in a health promoting entity of the contributory healthcare scheme in Bogotá, Colombia between 2018 - .

Design: Mixed methods research.

Method: The study contemplates two components: a quantitative component using a quasi-experimental analytical design before and after longitudinal intervention to determine the effectiveness of the case management model and a qualitative descriptive design to understand the experience of the participants about the model.

Optimization of door-to-electrocardiogram time within a critical pathway for the management of acute coronary syndromes at a teaching hospital in Colombia.

Introduction: Door-to-electrocardiogram (D2E) time is recognized as one of the quality parameters in the attention of acute coronary syndromes. Electrocardiogram realization within periods below 10 minutes increases the possibility to achieve quick and effective reperfusion, which has an impact on outcomes.

Objective: To describe the results of a strategy whose goal is to improve the fulfillment of the D2E deadline below 10 minutes in adults who attend the emergency service due to chest pain with clinical suspicion of acute coronary syndromes.
