Short and long-term outcomes of decompressive craniectomy among patients with non-traumatic acute intracranial hypertension; A 5-year retrospective analysis of a referral center

Background: Decompressive craniectomy (DC) is performed for the management of the patients with acutely elevated intracranial pressure (ICP). Considering the paucity of the evidence regarding the outcome predictors in patients with non-traumatic raised ICP, we aimed to assess short- and long-term outcome related factors in DC subjects. Methods: In this cross-sectional study, health records of the patients who underwent DC for non-traumatic etiologies over the five years were interrogated and demographic data, clinical features, operative findings, and follow-up notes were collected. The primary short- and long-term outcomes were in-hospital mortality and functional status, respectively. Functional status was evaluated using Glasgow Outcome Scale (GOS) at 6-month follow-up. Results: Of the 223 eligible patients, 113 (50.7 %) were male and the mean age was 48.68 ± 13.97 years. In-hospital mortality rate was 48.4 % (n = 108). Of the survivors, 28 (30.4 %) had favorable outcomes (GOS 4–5). The most common post-operative complications were infection with respiratory source (n = 52, 23 %) and external cerebral herniation (n = 61, 27.4 %). Presence of diabetes mellitus (DM) (OR = 6.09; 95 % CI = 2.0–18.51; P = 0.001), subarachnoid hemorrhage (SAH) (OR = 5.61; 95 % CI = 1.47––21.3; P = 0.01), and prolonged duration of ICU-stay (OR = 1.37; 95 % CI: 1.03, 1.24; P = 0.006) were associated with in-hospital mortality. Also, preexisting DM was two times more prevalent among the subjects deceased in the hospital than those who survived. Conclusions: Concomitant SAH, DM, and prolonged ICU stay were associated with increased in-hospital mortality. In addition, preexisting DM may increase mortality rates, likely irrespective of age factor

Expression Analysis of Five Different Long Non-Coding Ribonucleic Acids in Nonsmall-Cell Lung Carcinoma Tumor and Tumor-Derived Exosomes

Long non-coding ribonucleic acids (LncRNAs) are recently known for their role in regulating gene expression and the development of cancer. Controversial results indicate a correlation between the tissue expression of LncRNA and LncRNA content of extracellular vesicles. The present study aimed to evaluate the expression of different LncRNAs in non-small cell lung cancer (NSCLC) patients in tumor tissue, adjacent non-cancerous tissue (ANCT), and exosome-mediated lncRNA. Tumor and ANCT, as well as serum samples of 168 patient with NSCLC, were collected. The GHSROS, HNF1A-AS1, HOTAIR, HMlincRNA717, and LINCRNA-p21 relative expressions in tumor tissue, ANCT, and serum exosomes were evaluated in NSCLC patients. Among 168 NSCLC samples, the expressions of GHSROS (REx = 3.64, p = 0.028), HNF1A-AS1 (REx = 2.97, p = 0.041), and HOTAIR (REx = 2.9, p = 0.0389) were upregulated, and the expressions of HMlincRNA717 (REx = −4.56, p = 0.0012) and LINCRNA-p21 (REx = −5.14, p = 0.00334) were downregulated in tumor tissue in contrast to ANCT. Moreover, similar statistical differences were seen in the exosome-derived RNA of tumor tissues in contrast to ANCT samples. A panel of the five lncRNAs demonstrated that the area under the curve (AUC) for exosome and tumor was 0.937 (standard error: 0.012, p value < 0.0001). LncRNAs GHSROS, HNF1A-AS1, and HOTAIR showed high expression in tumor tissue and exosome content in NSCLC, and a panel that consisted of all five lncRNAs improved diagnosis of NSCLC
