Comparison of four pharmacological strategies aimed to prevent the lung inflammation and paraquat-induced alveolar damage.

ABSTRACT:

Objective

The aim of this study was to compare in vivo effect of five pharmacological options on inflammation and pulmonary fibrosis induced by paraquat.

Methods

54 Wistar SPF rats were used. After 2 h post-intoxication with paraquat ion, groups of 9 animals were randomly assigned to (1) cyclophosphamide plus dexamethasone (2) low molecular weight heparin (3) unfractionated heparin (4) vitamin C every 24 h, (5) atorvastatin or (6) placebo with intraperitoneal saline. Lung inflammation, alveolar injury, hepatocyte damage, hepatic regeneration, acute tubular necrosis and kidney congestion were evaluated.

Results

In the control group 100% of animals presented moderate and severe lung inflammation, while in the groups with atorvastatin and intratracheal heparin this proportion was lower (55.5%; CI 26.6-81.3%) (p?=?0.025). A lower degree of moderate or severe hepatic regeneration was evident in the treatment groups with atorvastatin (p?=?0.009). In this study was demonstrated that statins and heparin might have a protective effect in the paraquat-induced destructive phase. More evidence is needed to evaluated of dose-response effects of these drugs before to study in clinical trials.

Project description:Catheter-related infection is the third cause of infections in intensive care units (ICU), increasing the length of stay in ICU and hospital, mortality, and costs. Skin antisepsis is one of the most prevalent preventive measures. In this respect, it would appear preferable to recommend the use of alcoholic povidone iodine or chlorhexidine rather than aqueous povidone iodine. However, the data comparing chlorhexidine to povidone-iodine, both of them in alcoholic solutions, remain limited. Moreover, the benefits of enhanced cleaning prior to disinfection of skin that is not visibly soiled have yet to be confirmed in a randomized study.A prospective multicenter, 2 × 2 factorial, randomized-controlled, assessor-blind trial will be conducted in 11 intensive care units in six French hospitals. All adult patients aged over 18 years requiring the insertion of at least one peripheral arterial catheter and/or a non-tunneled central venous catheter and/or a hemodialysis catheter and/or an arterial pulmonary catheter will be randomly assigned to have all their catheters cared with one of four skin preparation strategies (2% chlorhexidine/70% isopropyl alcohol or 5% povidone iodine/69% ethanol with or without prior skin scrubbing). At catheter removal, catheter tips will be quantitatively cultured. Sets of aerobic and anaerobic blood cultures will be routinely obtained when a patient has fever, hypothermia, or other indications. In case of suspected catheter-related infection the patient's form will be reviewed by an independent adjudication committee. We plan to enroll 2,400 patients (4,800 catheters). The main objective is to demonstrate that use of 2% alcoholic chlorhexidine compared to 5% alcoholic povidone iodine in skin preparation lowers the rate of catheter-related infection. The second endpoint is to demonstrate that enhanced skin cleaning prior to disinfection of skin that is not visibly soiled does not reduce catheter colonization. Other outcomes include comparison of skin colonization at catheter insertion site, comparison of catheter colonization and catheter-related bacteremia taking place during implementation of the four strategies of skin preparation, and cutaneous tolerance, length of hospitalization, mortality, and costs.This study will help to update recommendations on the choice of an antiseptic agent to use in skin preparation prior to insertion of a vascular catheter and, by extension, of an epidural catheter and it will likewise help to update recommendations on the usefulness of skin scrubbing prior to disinfection when the skin is not visibly soiled.Clinicaltrials.gov number NCT01629550.

Project description:ImportanceMistreatment of medical students is pervasive and has negative effects on performance, well-being, and patient care.ObjectiveTo document the published programmatic and curricular attempts to decrease the incidence of mistreatment.Data sourcesPubMed, Scopus, ERIC, the Cochrane Library, PsycINFO, and MedEdPORTAL were searched. Comprehensive searches were run on "mistreatment" and "abuse of medical trainees" on all peer-reviewed publications until November 1, 2017.Study selectionCitations were reviewed for descriptions of programs to decrease the incidence of mistreatment in a medical school or hospital with program evaluation data. A mistreatment program was defined as an educational effort to reduce the abuse, mistreatment, harassment, or discrimination of trainees. Studies of the incidence of mistreatment without description of a program, references to a mistreatment program without outcome data, or a program that has never been implemented were excluded.Data extraction and synthesisAuthors independently reviewed all retrieved citations. Articles that any author found to meet inclusion criteria were included in a full-text review. The data extraction form was developed based on the guidelines for Best Evidence in Medical Education. An assessment of the study quality was conducted using a conceptual framework of 6 elements essential to the reporting of experimental studies in medical education.Main outcomes and measuresA descriptive review of the interventions and outcomes is presented along with an analysis of the methodological quality of the studies. A separate review of the MedEdPORTAL mistreatment curricula was conducted.ResultsOf 3347 citations identified, 10 studies met inclusion criteria. Of the programs included in the 10 studies, all were implemented in academic medical centers. Seven programs were in the United States, 1 in Canada, 1 in the United Kingdom, and 1 in Australia. The most common format was a combination of lectures, workshops, and seminars over a variable time period. Overall, quality of included studies was low and only 1 study included a conceptual framework. Outcomes were most often limited to participant survey data. The program outcome evaluations consisted primarily of surveys and reports of mistreatment. All of the included studies evaluated participant satisfaction, which was mostly qualitative. Seven studies also included the frequency of mistreatment reports; either surveys to assess perception of the frequency of mistreatment or the frequency of reports via official reporting channels. Five mistreatment program curricula from MedEdPORTAL were also identified; of these, only 2 presented outcome data.Conclusions and relevanceThere are very few published programs attempting to address mistreatment of medical trainees. This review identifies a gap in the literature and provides advice for reporting on mistreatment programs.

Project description:Objective:Paraquat (PQ), a widely used toxic herbicide, induces lung inflammation through mechanisms that remain incompletely understood. In a previous study, we found that the plasma MUC5B mucin level was implicated in PQ poisoning in patients. Here, we hypothesize that MUC5B is a critical mediator in PQ-induced cell inflammation. Methods:A mouse model of PQ-induced lung injury was used to examine the MUC5B expression level. A549 cells (alveolar epithelial cells line) were exposed to PQ in dose-dependent and time-dependent manners. Cell viability was detected by CCK-8 assays. The expression levels of MUC5B were examined by dot blot enzyme-linked immunosorbent assay (ELISA) and RT-qPCR. Western blotting was used to detect the levels of proteins in the MAPK and NF-?B pathways. Inflammatory factors in the cell culture medium were measured by ELISA. NF-?B and MAPK pathway inhibitors and MUC5B siRNA (siMUC5B) were used to determine the function of MUC5B. Finally, N-acetyl-cysteine (NAC) was added and its regulatory effect on the MAPK-NF-?B-MUC5B pathway was examined in PQ-induced cell inflammation. Results:MUC5B was significantly upregulated accompanying the increases in TNF-? and IL-6 secretion following PQ treatment in mouse and also in A549 cells after treatment with 50??M PQ at 24 hours. Furthermore, MAPK and NF-?B pathway inhibitors could dramatically decrease the expression of MUC5B and the secretion of TNF-? and IL-6. Importantly, siMUC5B could significantly attenuate the secretion of TNF-? and IL-6 induced by PQ. As expected, the addition of NAC efficiently suppresses the TNF-? and IL-6 secretion stimulated from PQ and also downregulated ERK, JNK, and p65 phosphorylation (ERK/JNK MAPK and NF-?B pathways) as well as MUC5B expression. Conclusion:Our findings suggest that MUC5B participates in the process of PQ-induced cell inflammation and is downstream of the NF-?B and MAPK pathways. NAC can attenuate PQ-induced cell inflammation at least in part by suppressing the MAPK-NF-?B-MUC5B pathway. These results nominate MUC5B as a new biomarker and therapeutic target for PQ-induced lung inflammation.
