Background: Retraction of articles occurs as a result of scientific misconducts or honest errors. Objectives: This study aimed to identify the frequency of retracted Iranian publications, compared to those of other countries and adjust them with influential parameters. Methods: All publications that were indexed on the Scopus database from 2008 to 2017 and then retracted, due to scientific misconduct were extracted through the Retraction Watch database and selected as the research community. To calculate the growth of retraction for each proposed country (or region), first, the rate of an absolute number of retracted papers for the years 2013-2017 was divided by the similar number for years 2008-2012, then this rate was adjusted to the retracted rate which is similarly computed for the total retracted statistics of the world. Results: Overall, 545 Iranian retracted publications from 2008 to 2017 were identified, of which 240 and 305 retracted articles were related to the first five years and the second five years of the study, respectively. The results showed that less than 1% (0.82) of all scientific articles published by Iranian researchers were retracted. However, the rate of retracted scientific articles in Iran compared to this rate in the world was significantly higher. Conclusion: Although retracted Iranian publications make up a small percentage of all Iranian publications, the number of retracted publications is increasing. It is important to recognize the reasons for scientific misconducts and to provide researchers with proper education.

Background: Endotracheal intubation (EI) associated with mechanical ventilation (MV) is frequently performed in critically ill patients admitted to intensive care unit (ICU) with sepsis. Objectives: This study aimed to assess the impact of important factors on the duration of tracheal intubation in patients with sepsis at the ICU admission. Methods: Adult patients admitted to the mixed medical–surgical ICUs with sepsis at the ICU admission who needs prolonged mechanical ventilation (PMV) (≥ 21 days) were included in this retrospective secondary analysis study. The primary outcome was ICU mortality. Baseline demographic and clinical characteristics of all patients were assessed as risk factors associated with the duration of MV by univariate and multivariate Binary logistic regression. Results: Eighty-five patients required more than 21 days of MV. Out of the 85 patients, 52 (61.2%) patients were intubated within 30 to 34.50 days and 33 (38.8%) patients had intubation within 34.51 to 65 days, and categorized as PMV and very prolonged MV groups, respectively. Two parameters were significantly associated with very prolonged MV which are as follows: older age 1.229 (95% CI: 1.002-1.507, P = 0.048) and long hospital stay (LOS) 2.996 (95% CI: 1.676-5.356, P < 0.001). No significant survival difference was observed between the two groups of study. (33.3% vs. 25%, P = 0.406). Conclusion: Our observations showed that the older age and LOS as pre-ICU stay in patients with positive sepsis at the ICU admission can prolong the duration of intubation. In addition, no significant survival difference was observed between patients with PMV and very prolonged MV.

Background: Sepsis is a very common serious medical condition among patients admitted to the intensive care units (ICUs) that increases with age and ICU length of stay (LOS). Objectives: The primary goal of this study was to estimate the mortality rate due to sepsis among adult patients admitted to the mixed medical–surgical ICUs for a long time. The secondary goal was to identify factors associated with predicting ICU mortality in individuals with long-term ICU LOS. Methods: Adult patients admitted to the medical ICU for a long time (≥75 days) were included in this retrospective secondary analysis study. Baseline demographic, clinical, and laboratory data were recorded upon inclusion in the study. Results: ICU mortality occurred in 78 (43.1%) patients, out of 188 participants. A greater portion of patients with sepsis at admission (62.7%) were observed in the death group (59.2% vs. 30.8%, P < 0.001), than the survivor group. Additionally, survived patients differed significantly in terms of age, family engagement, baseline cognitive impairment, activity, nurse anticipated turnover scale (ATS), duration of a mechanical ventilator (MV), and ICU LOS. The results of multivariate binary logistic regression showed that the older age and low family intervention can increase the risk of mortality in patients with sepsis at the time of admission, with a long ICU LOS. Conclusion: Our findings are crucially important to increase the awareness of the impact of sepsis, highlight the need for continued research into potential preventive and therapeutic interventions, and help guide resource allocation.
