In this research, the synthesis of novel derivatives of spiroisatins in high yields was investigated. These new compounds were synthesized using a multicomponent reaction (MCR) of isatin, malononitrile, acetophenone derivatives, diethyl oxalate, primary amines, and Et3N in aqueous media. Under similar conditions, spiropyrroloisatins were prepared using MCRs of synthesized spiroistins. The antioxidant activity of newly synthesized spiroisatins is due to having an NH group which was evaluated by two procedures. Also, the antimicrobial activity of newly generated spiroisatins was evaluated by a disk distribution process utilizing two kinds of Gram‐negative bacteria and Gram‐positive bacteria and bacterial growth was stopped using these compounds. The advantages of this method are short reaction times, high yields of products, and the easy separation of catalyst and product using simple procedures. [ABSTRACT FROM AUTHOR]

Background: Studies show that leaving the hospital with personal consent is increasing. This phenomenon has unpleasant and sometimes irreversible consequences. This study aims to investigate the causes and consequences of leaving the hospital with the personal consent of patients referred to the emergency department of hospitals affiliated with Qom University of Medical Sciences in 2021. Materials and Methods: In this descriptive-analytical study, 345 patients were selected who, with personal consent, left the emergency department of selected hospitals affiliated with Qom University of Medical Sciences in 2021. The study data were collected via a questionnaire and a checklist. The questionnaire comprised demographic variables, patientrelated factors, personnel-related factors, and hospital-related factors. The checklist of the consequences included questions about leaving the hospital with personal consent. The data were analyzed using descriptive and inferential statistics in SPSS software, version 20. Results: Of 345 patients included in the study, 55.9% were male and the mean age of patients was 47.1 years. The most important reasons for leaving the hospital with personal consent were as follows: personal reasons (22.9%), fear of continuing treatment (11.9%), preference to continue the treatment in other medical centers (9.3%), the suggestion of other hospital staff (35.1%), not having the desired doctor (27%), nurses' suggestion (19.4%), lack of care (20.4%), and inadequate hospital space and facilities (14.0%). The consequences of leaving the hospital with personal consent in this study included re-admission and hospitalization (10.3%), mortality (3.4%), heart disease (0.87%), and mental disorders (0.57%). Conclusion: After identifying the reasons for leaving the hospital with personal consent and highlighting the irreparable human and financial consequences, these causes should be eliminated to prevent irreparable and unfortunate consequences. Such causes include personal reasons, fear of continuing the treatment, and lack of care. Fixing the causes requires proper planning and effective actions. [ABSTRACT FROM AUTHOR]

Context: In some studies, Fresh Frozen Plasma (FFP) transfusion in severely ill patients was accompanied with an increase in the risk of nosocomial infection. However, there are no comprehensive data in terms of FFP transfusion and its relationship with nosocomial infection in heart surgery. Hence, the present systematic review and meta-analysis aimed to investigate the relationship between FFP transfusion and nosocomial infection risk in the patients undergoing cardiac surgery. Evidence Acquisition: Study selection: The present study included all the studies, which probed into nosocomial infection after FFP transfusion in patients with cardiac surgery. Data sources: Medline, Web of Science, Embase, Central, and Scopus electronic databases were searched to the end of March 2019. Results: Finally, five articles and three abstracts that studied nosocomial infection were entered into the present systematic review. FFP increased the rate of nosocomial infection in cardiac surgery in one article, but this was not the case in the remaining four articles. The three abstracts also reported that FFP increased the rate of nosocomial infection in cardiac surgery. Conclusion: The studies indicated that the benefit of FFP administration outweighed the probable risk of infection. Indeed, none of the studies indicated a strong relationship between FFP transfusion and infection rate after cardiac surgery. [ABSTRACT FROM AUTHOR]

Hiccups that last more than 48 hours are known as persistent hiccups. A 38-year-old man presented to the emergency with a 3-day history of persistent hiccups, and after partial treatment and normal test results, he was discharged from the emergency. After 22 hrs, he was brought to the emergency again with a complaint of stuttering and was admitted with a chance of stroke. A 50% stenosis development in the right carotid artery was reported, and the MRI results were normal. After 20 hrs of admission, the patient's stutter was thoroughly treated, and he was discharged with the diagnosis of TIA. Persistent hiccups can be a precursor to a stroke. [ABSTRACT FROM AUTHOR]

Introduction: There is no comprehensive meta-analysis on the value of physiological scoring systems in predicting the mortality of critically ill patients. Therefore, the present study intended to conduct a systematic review and meta-analysis to collect the available clinical evidence on the value of physiological scoring systems in predicting the in-hospital mortality of acute patients., Method: An extensive search was performed on Medline, Embase, Scopus, and Web of Science databases until the end of year 2020. Physiological models included Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), modified REMS (mREMS), and Worthing Physiological Score (WPS). Finally, the data were summarized and the findings were presented as summary receiver operating characteristics (SROC), sensitivity, specificity and diagnostic odds ratio (DOR)., Results: Data from 25 articles were included. The overall analysis showed that the area under the SROC curve of REMS, RAPS, mREMS, and WPS criteria were 0.83 (95% CI: 0.79-0.86), 0.89 (95% CI: 0.86-0.92), 0.64 (95% CI: 0.60-0.68) and 0.86 (95% CI: 0.83-0.89), respectively. DOR for REMS, RAPS, mREMS and WPS models were 11 (95% CI: 8-16), 13 (95% CI: 4-41), 2 (95% CI: 2-4) and 17 (95% CI: 5-59) respectively. When analyses were limited to trauma patients, the DOR of the REMS and RAPS models were 112 and 431, respectively. Due to the lack of sufficient studies, it was not possible to limit the analyses for mREMS and WPS., Conclusion: The findings of the present study showed that three models of RAPS, REMS and WPS have a high predictive value for in-hospital mortality. In addition, the value of these models in trauma patients is much higher than other patient settings., Competing Interests: The authors declared no conflict of interest.
