Galectin-3 and Fibrosis: Research in the Last 5 Years
Isaac Eliaz

Tissue fibrosis is initially an adaptive response to organ injury, but eventually, parenchymal scarring and subsequent cellular dysfunction and organ failure ensue. Few therapies currently exist for fibrosis, especially those that target fibrogenesis. Galectin-3 (Gal-3) is a member of the lectin family of proteins, is produced predominantly by macrophages, and has essential functions in inflammation and angiogenesis. Gal-3 is activated in fibrotic models and abnormally elevated in fibrotic patients. Gal-3 inhibitors help to ameliorate or prevent fibrosis. For this review, we searched for original articles and reviews published between Jul 1, 2014, and Nov 1, 2019, using the following search terms (or combination of words) in PubMed: “galectin 3”, “fibrosis”, “heart”, “cardiac”, “liver”, “hepatic”, “lung”, “pulmonary”, “kidney”, and “renal”.

Following the initial introduction of clinical decision support systems (CDSS) into the clinical practice in the 1970s, the complexity and performance quality of CDSSs have increased. The current literature on the efficacy and effectiveness of such systems shows conflicting results. While some studies show a clear benefit in quality-of-care improvement, others fail to replicate these outcomes. Heterogeneity of studies and the complexity of CDSS characteristics drive these conflicting conclusions. The lower cost and the easier implementation of pragmatic clinical trials provide an excellent platform to prove the effectiveness of CDSS in the real-world scenarios. To achieve better results, a series of explanatory trials are needed to identify the most effective CDSS in controlled settings. Therefore, utilization of both explanatory and pragmatic trial designs is necessary to evaluate the safety and efficacy of CDSS on the care of patients with acute kidney injury (AKI) in the acute setting. In this review, the authors provide an overview of the literature on critical care-related CDSS, its characteristics and dimensions, differences between pragmatic and explanatory trials, and potential proposals for both trial designs for AKI.

Artificial intelligence provides a vast opportunity and conquest of the science of knowledge. Twenty-first-century medicine will be characterized by an extraordinary ability to access and process medical information to provide patient-specific, timely, and effective clinical decision support. The knowledge gained by patient care experience and clinicians' expertise has led to many clinical care advances. Access to a large volume of data, along with ever-growing information and knowledge of diseases, can allow us to optimize diagnoses and management strategies by using advances in machine learning and artificial intelligence. Changing the medical culture from only relying on the experts to use medical informatics advances to improve the experts' clinical judgment would be an uphill battle. It is necessary to overcome the clinicians' traditional training to empower them into moving in the data science, statistics, and artificial intelligence era. As the incorporation of artificial intelligence in clinical practice seems inevitable, a thorough understanding of its capacities and flaws is essential to the emergence of a new clinical practice world. This review paper describes some of the nuances of past, current, and future clinical decision support systems and artificial intelligence's impact on this process.

REVIEW ARTICLE
Indices of Tissue Perfusion: Triggers of Targets of Resuscitation?
Daniel De Backer, Marie Van Hove, Pierre Foulon, Joe Kadou, Gregoire Michiels, Simone Giglioli

Circulatory shock is characterized by a decrease in oxygen delivery to the tissues associated with impairment in oxygen metabolism and tissue hypoxia. Clinical and biological signs of impaired tissue perfusion and tissue hypoxia are used as bedside to detect circulatory failure and trigger resuscitation procedures. The most popular signs of tissue hypoperfusion include mean arterial pressure, capillary refill time and mottling score, central venous oxygen saturation (ScvO

), veno-arterial difference in PCO
2
(PvaCO
2
), microcirculation assessment, and lactate. Both the severity and duration of the alterations in any of these variables are associated with a poor outcome so that it sounds logical to trigger therapy based on these. Using these variables as target for therapy is much more complex. Some of the limits for using some of these variables as targets include an incertitude about the target to reach (should we aim at normalizing or improving the variable, and by how much?) and the time lag between resolution of impaired tissue perfusion/hypoxia and normalization of the variable. The ideal target variable should have a well-defined end point and a rapid response time. Interestingly, hemodynamic resuscitation targeting these variables gave variable results. In this review, we will discuss the interest and limitations of the above-mentioned indices of tissue perfusion and hypoxia as trigger as well as end point of resuscitation in critically ill patients.

Severely ill neurosurgical patients are those who present with pathologies of the nervous system associated with either a high mortality or that which leaves significant sequelae in those who survive. Desmopressin is a synthetic analog of the antidiuretic hormone that is stored in neurohypophysis. Its function is to decrease urinary volume by increasing reabsorption of water in the convoluted tubules and nephron collectors, additionally increasing the expression of coagulation factor VII and the von Willebrand factor. For this reason, its usefulness in the management of various pathologies has been tested, from coagulopathies to posttraumatic and postsurgical diabetes insipidus. It contributes in improving hyponatremia and in maintaining the balance of fluids and electrolytes in traumatic brain injury and subarachnoid hemorrhage (SAH) patients. It has been additionally studied for its role in the risk of rebleeding in SAH patients and in those with coagulopathies, where its implicated mechanism of action is through platelet anti-aggregation.

Despite decades of efforts, severe traumatic brain injury (TBI) is still the leading cause for mortality and immobility of children and young adults worldwide and is a great burden to the health-care system. After injury, the oxygen supply is conventionally considered the monitoring parameter in a neurosurgical Intensive Care Unit. However, the overall mortality rate has only slightly improved since the late twentieth century. Evolving evidence suggests that dysfunction of oxygen utilization might be the underlying pathophysiology of secondary brain injury, which should also be a key parameter for multimodal monitoring and management after severe TBI. In this review, we summarize the current and advanced understanding of multimodal monitoring for severe TBI along with novel noninvasive technologies in this field. By continuously monitoring patients with severe TBI, the use of multimodal monitoring technologies including (but not limited to) computed tomography, cerebral microdialysis, near-infrared spectroscopy, magnetic resonance spectroscopy, high-performance liquid chromatography, and magnetic induction phase shift method will be crucial for observing disease changes such as intracranial pressure and brain tissue oxygen partial pressure as well as developing potential therapeutic strategies after severe TBI.

DOI
:10.4103/jtccm.jtccm_7_18
Acute kidney injury (AKI) is a common complication of acute illness and carries a significant risk of mortality and morbidity, resulting in high health-care-associated costs. The incidence of AKI appears to be rising, making it ever more important to understand its acute and chronic consequences. In this review, we explore the evolving epidemiology of AKI, describe the impact of AKI on other organs, and discuss the short- and long-term effects of AKI on mortality and morbidity and its economic burden.

Ehsan Ahmadnia, Anna Hall, Marlies Ostermann
2019, 1:7 (3 January 2019)
DOI
:10.4103/jtccm.jtccm_1_18
Interest in the use of angiotensin (AT) (particularly in the context of shock) had been rekindled by recent randomized trial data (notably the AT II for the Treatment of High-Output Shock-3 study). This review article outlines the renin–AT system in health and during sepsis as well as the proposed clinical uses of AT II. The potential for wider application within critical care is also considered.
