This review aims to explore the clinical and research applications of artificial intelligence (AI), particularly machine learning (ML) and deep learning (DL), in understanding, predicting, and managing obesity. It assesses the use of AI tools to identify obesity-related risk factors, predict outcomes, personalize treatments, and improve healthcare interventions for obesity. A comprehensive literature search was conducted using PubMed and Google Scholar, with keywords including "artificial intelligence", "machine learning", "deep learning", "obesity", "obesity management", and related terms.

The 2024 European Society of Intensive Care Medicine clinical practice guideline provide clinicians with evidence-based recommendations on intravenous fluid in critically ill adults across a range of common conditions. These guidelines aim to improve the practices of fluid therapy by adopting a global perspective that considers both clinical efficacy and resource utilization in diverse healthcare settings. The guidelines address three key questions: (1) albumin versus crystalloids, (2) balanced crystalloids versus isotonic saline, and (3) small-volume hypertonic solutions versus isotonic crystalloids.

Background: Feeding intolerance is common in critically ill patients and can lead to malnutrition. Prokinetic agents may be used to enhance the uptake of nutrition. However, the evidence on the effectiveness and safety of prokinetic agents is sparse, and there is a lack of data on their use in intensive care units (ICU).

Article Synopsis
  • The Rapid Practice Guideline (RPG) was created to evaluate the effectiveness of ketamine for sedation in ICU patients on mechanical ventilation compared to other sedatives or usual care, while also highlighting areas for further research.
  • A panel of 23 experts, including a patient representative, conducted a systematic review and meta-analysis to gather data, using a structured approach to assess the reliability and implications of the evidence collected.
  • The findings indicated considerable uncertainty regarding the effects of ketamine, with low certainty about its benefits on reducing opioid use or mechanical ventilation duration; adjunct ketamine therapy did not significantly affect mortality within 28 days.

Background: This Rapid Practice Guideline (RPG) aimed to provide evidence-based recommendations for ketamine analgo-sedation (monotherapy and adjunct) versus non-ketamine sedatives or usual care in adult intensive care unit (ICU) patients on invasive mechanical ventilation (iMV) and to identify knowledge gaps for future research.

Methods: The RPG panel comprised 23 multinational multidisciplinary panelists, including a patient representative. An up-to-date systematic review and meta-analysis constituted the evidence base.

Article Synopsis
  • - The Intensive Care Medicine Rapid Practice Guideline (ICM-RPG) provides evidence-based recommendations for using small-volume versus conventional blood collection tubes in adult ICU patients.
  • - A systematic review of 23 panelists across 8 countries revealed high certainty that small-volume tubes minimize blood sampling volume and show moderate certainty in reducing transfusion risks, despite some imprecision in the data.
  • - The panel strongly recommends small-volume tubes due to their benefits, including reduced waste and successful implementation in various countries, although there are initial costs related to validating these tubes for laboratory use.

Article Synopsis
  • Critically ill adults can suffer from stress-related mucosal damage leading to upper gastrointestinal bleeding (UGIB), necessitating preventive measures in ICU settings.
  • A panel of 18 international experts developed evidence-based guidelines using the GRADE methodology to provide recommendations for reducing UGIB risk in adult ICU patients.
  • The panel's findings indicate several risk factors for UGIB, such as coagulopathy and shock, and recommend using proton pump inhibitors or histamine-2 receptor antagonists for at-risk patients, while emphasizing that enteral nutrition may help mitigate risk.

Article Synopsis
  • A study was conducted to evaluate the effects of the proton-pump inhibitor pantoprazole on critically ill patients undergoing invasive ventilation, comparing it to a placebo.
  • The trial included 4,821 patients and found that pantoprazole significantly reduced the incidence of clinically important upper gastrointestinal bleeding compared to placebo (1.0% vs. 3.5%).
  • However, there was no significant difference in overall mortality rates at 90 days between the pantoprazole group (29.1%) and the placebo group (30.9%).

Background: The goal of this systematic review was to examine the efficacy and safety of proton-pump inhibitors for stress ulcer prophylaxis in critically ill patients.

Methods: We included randomized trials comparing proton-pump inhibitors versus placebo or no prophylaxis in critically ill adults, performed meta-analyses, and assessed certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations approach. To explore the effect of proton-pump inhibitors on mortality based on disease severity, a subgroup analysis was conducted combining within-trial subgroup data from the two largest trials and assessed credibility using the Instrument for Assessing the Credibility of Effect Modification Analyses.

Article Synopsis
  • During the COVID-19 pandemic, many ICUs paused ongoing research to prioritize studies related to the virus, but the REVISE trial continued investigating stress ulcer prophylaxis in mechanically ventilated patients.
  • The trial, which compares pantoprazole against a placebo, enrolled 2,961 patients across 59 centers, despite facing disruptions in enrollment during the pandemic.
  • Changes in the informed consent process included a shift to a 'consent to continue' model and an increase in telephone consent due to restrictions, leading to a slight rise in overall consent rates.

Objectives: To describe the productivity, performance, and impact of medical research in the Arab world countries.

Methods: We carried out a bibliometric analysis using Clarivate Analytics databases from January 2017 to March 2023. We reported research productivity, national and international research collaboration patterns, impact of Arab medical research output compared to the global average, top medical journals publishing Arab-affiliated research, and performance of the most productive Arab institutions.

Purpose: The ordering of routine blood test panels in advance is common in intensive care units (ICUs), with limited consideration of the pretest probability of finding abnormalities. This practice contributes to anemia, false positive results, and health care costs. We sought to understand practices and attitudes of Canadian adult intensivists regarding ordering of blood tests in critically ill patients.

Article Synopsis
  • Some recent studies found that benzodiazepines might help prevent nausea and vomiting after surgery, but doctors haven't added them to the official guidelines yet because they worry about side effects.
  • Researchers reviewed lots of studies and found that using benzodiazepines before or after surgery can lower the chances of feeling sick or throwing up.
  • The results from this research will help update future guidelines for doctors on how to prevent nausea and vomiting after surgery.

The aim of this Intensive Care Medicine Rapid Practice Guideline (ICM-RPG) was to provide evidence-based clinical guidance about the use of higher versus lower oxygenation targets for adult patients in the intensive care unit (ICU). The guideline panel comprised 27 international panelists, including content experts, ICU clinicians, methodologists, and patient representatives. We adhered to the methodology for trustworthy clinical practice guidelines, including the use of the Grading of Recommendations Assessment, Development, and Evaluation approach to assess the certainty of evidence, and used the Evidence-to-Decision framework to generate recommendations.

Importance: Blood collection for laboratory testing in intensive care unit (ICU) patients is a modifiable contributor to anemia and red blood cell (RBC) transfusion. Most blood withdrawn is not required for analysis and is discarded.

Objective: To determine whether transitioning from standard-volume to small-volume vacuum tubes for blood collection in ICUs reduces RBC transfusion without compromising laboratory testing procedures.
