Special Issue Information

Dear Colleagues,

We are delighted to present this Special Issue of the International Journal of Molecular Sciences: “Diagnostic and Therapeutic Advances in the Management of Sepsis and Septic Shock—2nd Edition”, as Volume 1 of the Special Issue was successful.

The conceptual framework for the diagnosis of sepsis, septic shock and endotoxic shock has multiple steps, including an initial evaluation of the etiology and clinical features, assessment of the primary hemodynamic manifestations, and consideration of the alterations in cellular biology and the degree of local tissue injury. The prompt diagnosis of septic shock begins with obtainment of the patient’s medical history and the performance of a physical examination to identify the signs and symptoms of infection; the patient may also require focused ultrasonography to recognize more complex physiologic manifestations of shock. The identification of biomarkers is particularly important to understand molecular mechanisms and diagnose sepsis, enabling early intervention, which can reduce the risk of death. In fact, a sample treatment algorithm for septic shock typically proceeds through the rescue, optimization, stabilization, and de-escalation of care. Many adjunctive treatments in septic shock target perturbations in the innate immune response and coagulation cascade. An example of this is extracorporeal blood purification therapy, which has been proposed to improve outcomes in patients with sepsis. Therefore, IJMS is proud to offer this platform to promote and highlight valuable research on “Diagnostic and Therapeutic Advances in the Management of Sepsis and Septic Shock—2nd Edition”.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Sepsis continues to overwhelm hospital systems with its high mortality rate and prevalence. A strategy to reduce the strain of sepsis on hospital systems is to develop a diagnostic/prognostic measure that identifies patients who are more susceptible to septic death. Current biomarkers fail to achieve this outcome, as they only have moderate diagnostic power and limited prognostic capabilities. Sepsis disrupts a multitude of pathways in many different organ systems, making the identification of a single powerful biomarker difficult to achieve. However, a common feature of many of these perturbed pathways is the increased generation of reactive oxygen species (ROS), which can alter gene expression, changes in which may precede the clinical manifestation of severe sepsis. Therefore, the aim of this study was to evaluate whether ROS-related circulating molecular signature can be used as a tool to predict sepsis survival. Here we created a ROS-related gene signature and used two Gene Expression Omnibus datasets from whole blood samples of septic patients to generate a 37-gene molecular signature that can predict survival of sepsis patients. Our results indicate that peripheral blood gene expression data can be used to predict the survival of sepsis patients by assessing the gene expression pattern of free radical–associated -related genes in patients, warranting further exploration.
