Such differences are explained by the difference in the immune response and organ reactions to infection. To counter this diversity, scientists have started to classify the patients into subphenotypes to determine whether the treatment can be planned in an individualized way. The objective of this review is to determine the methods of determining sepsis subphenotypes and their role in clinical practice. To conduct this review, a search in PubMed was conducted on studies published between 2015 and 2025. Papers that provided explicit information about the process of subphenotype identification were included. Articles that lacked the complete text, publications that were not published in English, and those that lacked the necessary methodological information were filtered out. In the chosen studies, there were several methods used, based on routinely available clinical variables; others were based on biomarkers, machine-learning techniques, time-varying trends in the dysfunction of organs, and transcriptomic data. Even though the methods are different, they have found many groups of patients who have significant differences in terms of inflammation, organ failure patterns, and response to treatment. According to the available evidence, there is no one such condition that sepsis represents, but rather a series of biologically different conditions. Subphenotyping can improve initial diagnosis and treatment, but most current methods are complex for clinical use. More efforts should be made to establish less complex tools, which may be implemented consistently at the bedside.</p>","PeriodicalId":51593,"journal":{"name":"Monaldi Archives for Chest Disease","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147845852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overall certainty of evidence was low due to methodological limitations and heterogeneity in outcome definitions and intervention protocols.

This is a cross-sectional study that included 150 subjects (100 psoriasis patients and 50 controls). After thorough history taking and complete general physical and dermatological examinations, the patients were divided into various grades of severity of the disease based on the Psoriasis Area Severity Index. Blood pressure of all subjects was measured. Patients with psoriasis have significantly higher levels of both systolic blood pressure and diastolic blood pressure than the controls (p=0.003 and p<0.001, respectively). A linear positive correlation was found between the systolic blood pressure (R²=0.768) and diastolic blood pressure (R²=0.550) and the duration of the disease. Similarly, a significant linear positive correlation was found between the severity of the disease and systolic blood pressure (R²=0.196) and also the diastolic blood pressure (R²=0.119).

We conducted this animal pilot study to investigate the biocompatibility of a next-generation nanocomposite silicone airway stent, engineered with 3wt% hydrophobic nano-silica reinforcement. Innovative characteristics of the stent include improved biocompatibility and reduced mucus adhesion due to its hydrophobic properties. A refined stenting technique was applied to implant the stent in the trachea of two sheep models by assembling two endotracheal tubes, Ambu, and the stent. After a two-month follow-up, high-resolution computed tomography imaging, 3D virtual bronchoscopy, bronchoscopy, and biopsy of the tracheal wall were done. Histopathologic assessment demonstrated an inflammatory infiltrate dominated by lymphocytes, without stromal reactions, mucosal and submucosal thickening, or granulation, confirming a favorable tissue tolerance. These preliminary outcomes emphasize the stent's potential as a transformative therapeutic option; however, the study's limited sample size and absence of comparative controls highlight the necessity for further preclinical trials with quantitative airflow parameters to elucidate the clinical translatability of this innovative biomaterial solution for airway obstructions.
