Bibliometric study of sepsis-associated liver injury from 2000 to 2023.

BACKGROUND: Sepsis-associated liver injury (SLI) is a severe and prevalent complication of sepsis. AIM: To explore the literature on SLI via a bibliometric approach. METHODS: Reviews and articles correlated with SLI published from January 1, 2000 to October 28, 2023 were searched from the Web of Science Core Collection. Then, the searched data were analyzed using VOSviewer, CiteSpace, and R language. RESULTS: There were 787 publications involved in this paper, comprising 745 articles and 42 reviews. China, the United States, and Germany are the primary publication sources in this area. Studies related to SLI primarily focused on mechanisms of pathogenesis, as evidenced by analyzing keywords, references, and the counting of original research. These studies mainly involved tumor necrosis factor alpha, inflammation, oxidative stress, and nuclear factor-kappa B. CONCLUSION: There is significant growth in the research on SLI. Current investigations primarily involve basic experiments that aimed at uncovering pathogenic mechanisms. According to the analyzed literature, the identified pathogenic mechanisms and potential therapeutic targets serve as the foundation for translating findings from basic research to clinical applications.

Nirmatrelvir and ritonavir for inpatients with severe or critical COVID-19 beyond five days of symptom onset: a propensity score-matched, multicenter, retrospective cohort study.

BACKGROUND: There is an urgent need for therapeutic strategies for inpatients with severe or critical COVID-19. The evaluation of the clinical benefits of nirmatrelvir and ritonavir (Nmr/r) for these patients beyond five days of symptom onset is insufficient. METHODS: A new propensity score-matched cohort was constructed by using multicenter data from 6695 adult inpatients with COVID-19 from December 2022 to February 2023 in China after the epidemic control measures were lifted across the country. The severity of disease of the inpatients was based on the tenth trial edition of the Guidelines on the Diagnosis and Treatment of COVID-19 in China. The symptom onset of 1870 enrolled severe or critical inpatients was beyond five days, and they received either Nmr/r plus standard treatment or only standard care. The ratio of patients whose SOFA score improved more than 2 points, crucial respiratory endpoints, changes in inflammatory markers, safety on the seventh day following the initiation of Nmr/r treatment, and length of hospital stay were evaluated. RESULTS: In the Nmr/r group, on Day 7, the number of patients with an improvement in SOFA score ≥ 2 was much greater than that in the standard treatment group (P = 0.024) without a significant decrease in glomerular filtration rate (P = 0.815). Additionally, the rate of new intubation was lower (P = 0.004) and the no intubation days were higher (P = 0.003) in the first 7 days in the Nmr/r group. Other clinical benefits were limited. CONCLUSIONS: Our study may provide new insight that inpatients with severe or critical COVID-19 beyond five days of symptom onset benefit from Nmr/r. Future studies, particularly randomized controlled trials, are necessary to verify the above findings.

Effect of single-patient room design on the incidence of nosocomial infection in the intensive care unit: a systematic review and meta-analysis.

Background: Previous studies have yielded varying conclusions regarding the impact of single-patient room design on nosocomial infection in the intensive care unit (ICU). We aimed to examine the impact of ICU single-patient room design on infection control. Methods: We conducted a comprehensive search of PubMed, Embase, the Cochrane Library, Web of Science, CNKI, WanFang Data, and CBM databases from inception to October 2023, without language restrictions. We included observational cohort and quasi-experimental studies assessing the effect of single- versus multi-patient rooms on infection control in the ICU. Outcomes measured included the nosocomial infection rate, incidence density of nosocomial infection, nosocomial colonization and infection rate, acquisition rate of multidrug-resistant organisms (MDROs), and nosocomial bacteremia rate. The choice of effect model was determined by heterogeneity. Results: Our final analysis incorporated 12 studies involving 12,719 patients. Compared with multi-patient rooms in the ICU, single-patient rooms demonstrated a significant benefit in reducing the nosocomial infection rate (odds ratio [OR]: 0.68; 95% confidence interval [CI]: 0.59, 0.79; p < 0.00001). Analysis based on nosocomial infection incidence density revealed a statistically significant reduction in single-patient rooms (OR: 0.64; 95% CI: 0.44, 0.92; p = 0.02). Single-patient rooms were associated with a marked decrease in nosocomial colonization and infection rate (OR: 0.44; 95% CI: 0.32, 0.62; p < 0.00001). Furthermore, patients in single-patient rooms experienced lower nosocomial bacteremia rate (OR: 0.73; 95% CI: 0.59, 0.89; p = 0.002) and lower acquisition rate of MDROs (OR: 0.41; 95% CI: 0.23, 0.73; p = 0.002) than those in multi-patient rooms. Conclusion: Implementation of single-patient rooms represents an effective strategy for reducing nosocomial infections in the ICU.

The impact of stretch service goals on unethical behaviors of nurses: A three-wave cross-sectional study.

BACKGROUND: Stretch service goals strive to motivate healthcare practitioners to maintain high quality in service provision. However, little is known about how stretch service goals trigger nurses' unethical behavior. RESEARCH AIM: This study aimed to investigate the influence of stretch service goals on nurses' unethical behavior, as well as the mediating effects of patient entitlement and nurses' emotional dissonance. RESEARCH DESIGN: A quantitative cross-sectional study is designed. PARTICIPANTS AND RESEARCH CONTEXT: We sourced data by conducting a time-lagged three-wave survey study from March to September 2020. Random sampling was used, and data were collected from 422 nurse-patient pairs in Chinese hospitals. Bootstrapping method and structural equation modeling were employed to verify the conceptual model. ETHICAL CONSIDERATIONS: The study was approved by the designated authority within hospitals and ethical committees. RESULTS: Stretch service goals are not directly related to nurses' unethical behavior. Stretch service goals can trigger nurses' unethical behavior via patient entitlement. Patient entitlement and nurses' emotional dissonance play a chain-mediating role between stretch service goals and nurses' unethical behavior. CONCLUSIONS: In the context of the healthcare industry, nurses may engage in unethical behavior due to the pressure of achieving stretch service goals. This study contributes to opening the "black box" of stretch service goals and nurses' unethical behavior by exploring the chain-mediating effect of patient entitlement and nurses' emotional dissonance.

Effectiveness of nirmatrelvir-ritonavir versus azvudine for adult inpatients with severe or critical COVID-19.

BACKGROUND: In China, both nirmatrelvir-ritonavir (Paxlovid) and azvudine have been granted approval to treat adult SARS-CoV-2-infected patients with moderate symptoms. Information about the clinical effect of the two available agents among inpatients with severe or critical COVID-19 is scarce. PURPOSE: To compare the clinical outcomes of Paxlovid and azvudine among adult inpatients with severe or critical COVID-19. METHOD: We conducted a retrospective cohort study in two large medical centres after the epidemic control measures were lifted in China. A new propensity score matched-inverse probability of treatment weighting cohort was constructed to evaluate the in-hospital all-cause mortality, hospital length of stay, Sequential Organ Failure Assessment (SOFA) score and safety. RESULTS: A total of 955 individuals were in the cohort. The antiviral therapy strategies were decided by the senior physician and the supplies of the pharmacy. A total of 451 patients were in the Paxlovid group, and 504 patients were in the azvudine group. Compared with Paxlovid, the effects of azvudine on in-hospital all-cause mortality were not significantly different, and the OR (95% CI) was 1.084 (0.822 to 1.430), and the average hospital length of stay of patients discharged alive was also similar in the azvudine group, and the difference (day) and (95% CI) was 0.530 (-0.334 to 1.393). After 7 days of therapy, the degree of decline in the SOFA score was greater in the Paxlovid group than in the azvudine group (p<0.001). The change in glomerular filtration rate was not significantly different (p=0.824). CONCLUSION: Paxlovid and azvudine had similar effectiveness on in-hospital all-cause mortality and hospital length of stay. Compared with the azvudine group, after 7 days of therapy, the degree of decline in SOFA score was significantly higher in the Paxlovid group. These findings need to be verified in larger prospective studies or randomised controlled trials.

The active ingredients in Chinese peony pods synergize with antibiotics to inhibit MRSA growth and biofilm formation.

Staphylococcus aureus (S. aureus) is a zoonotic pathogen that infects both humans and animals. The rapid spread of methicillin-resistant S. aureus (MRSA) and its resistance to antibiotics, along with its ability to form biofilms, poses a serious challenge to the clinical application of traditional antibiotics. Peony (Paeonia lactiflora Pall.) is a traditional Chinese medicine with multiple pharmacological effects. This study observed the strong antibacterial and antibiofilm activity of the water extract (WE) and ethyl acetate extract (EA) of Chinese peony pods against MRSA. The combination of EA and vancomycin, cefotaxime, penicillin G or methicillin showed a synergistic or additive antibacterial and antibiofilm effects on MRSA, which is closely related to the interaction of 1,2,3,4,6-penta-O-galloyl-ß-D-glucose (PG) and methyl gallate (MG). The active ingredients in peony pods have been found to increase the sensitivity of MRSA to antibiotics and demonstrate antibiofilm activity, which is mainly related to the down-regulation of global regulatory factors sarA and sigB, extracellular PIA and eDNA encoding genes icaA and cdiA, quorum sensing related genes agrA, luxS, rnaIII, hld, biofilm virulence genes psma and sspA, and genes encoding clotting factors coa and vwb, but is not related to genes that inhibit cell wall anchoring. In vivo test showed that both WE and EA were non-toxic and significantly prolonged the lifespan of G. mellonella larvae infected with MRSA. This study provides a theoretical basis for further exploration of the combined use of PG, MG and antibiotics to combat MRSA infections.

Why Good Employees Do Bad Things: The Link between Pro-Environmental Behavior and Workplace Deviance.

Despite the significance of pro-environmental behavior (PEB) in the workplace, most of the existing studies have neglected its negative work outcomes. Drawing upon moral licensing theory and cognitive dissonance theory, we construct a conceptual model of the influence mechanism of employees' PEB (i.e., public-sphere PEB, private-sphere PEB) on workplace deviance through psychological entitlement, and the moderating effect of rationalization of workplace deviance on the relationship between psychological entitlement and workplace deviance. Using two-stage survey data from 216 employees in China, we performed hierarchical regression analysis and structural equation modeling method to test our hypotheses. Our findings reveal that public-sphere PEB positively affects psychological entitlement, while private-sphere PEB negatively affects psychological entitlement. Psychological entitlement further positively affects workplace deviance. In addition, rationalization of workplace deviance strengthens the positive impact of psychological entitlement on workplace deviance. This study offers novel insights into the dark side of PEB literature by exploring the PEB-workplace deviance relationship. This study also contributes to managerial implications of how PEB leads to workplace deviance and how to address this issue.

Hidden benefits of electric vehicles for addressing climate change.

There is an increasingly hot debate on whether the replacement of conventional vehicles (CVs) by electric vehicles (EVs) should be delayed or accelerated since EVs require higher cost and cause more pollution than CVs in the manufacturing process. Here we reveal two hidden benefits of EVs for addressing climate change to support the imperative acceleration of replacing CVs with EVs. As EVs emit much less heat than CVs within the same mileage, the replacement can mitigate urban heat island effect (UHIE) to reduce the energy consumption of air conditioners, benefitting local and global climates. To demonstrate these effects brought by the replacement of CVs by EVs, we take Beijing, China, as an example. EVs emit only 19.8% of the total heat emitted by CVs per mile. The replacement of CVs by EVs in 2012 could have mitigated the summer heat island intensity (HII) by about 0.94°C, reduced the amount of electricity consumed daily by air conditioners in buildings by 14.44 million kilowatt-hours (kWh), and reduced daily CO2 emissions by 10,686 tonnes.
