A qualitative study of the experiences of interdisciplinary nurses during the COVID-19 outbreak following the announcement of the "Ten new guidelines" in China.

BACKGROUND: On December 7, 2022, the Joint Prevention and Control Mechanism of China's State Council released the "Ten New Guidelines" to optimize the coronavirus disease 2019 (COVID-19) prevention policies further. This signaled a broader shift from "dynamic clearing" to "coexisting with the virus" nationwide. OBJECTIVE: This study aims to examine the experiences and perspectives of interdisciplinary nurses during the COVID-19 outbreak in China after the implementation of the "Ten New Guidelines". The goal is to understand the challenges faced by this unique nursing group and inform organizational support to bolster their well-being and resilience. METHODS: Two tertiary hospitals in southeastern Zhejiang Province were selected, with interdisciplinary nurses chosen as subjects. A constructivist qualitative research approach was employed, using semi-structured face-to-face interviews. Research data were collected through interviews and analyzed using content analysis. RESULTS: Fifteen interdisciplinary nurses were included in this study. The analysis revealed four main themes and nine sub-themes. The main themes were: (1) ineffective organizational support (inadequate organizational care, poor PPE, excessive workload), (2) physiological distress after contracting COVID-19 (extreme physical fatigue, leakage of urine due to severe coughing), (3) fear of being wrong (fear of being reprimanded in public, psychological anxiety), and (4) family responsibility anxiety (difficulty of loyalty and filial piety, obligations to their children). CONCLUSION: We provide new evidence that organizations must proactively address the support, training, and communication needs of staff, particularly interdisciplinary nurses, to supplement epidemic containment. This is also essential in helping mitigate the work-family conflicts such roles can create.

Effect of intermittent Pringle maneuver on perioperative outcomes and long-term survival following liver resection in patients with hepatocellular carcinoma: a meta-analysis and systemic review.

BACKGROUND: Intermittent Pringle maneuver (IPM) is commonly used to control bleeding during liver resection. IPM can cause ischemia-reperfusion injury, which may affect the prognosis of patients with hepatocellular carcinoma (HCC). The present meta-analysis was conducted to evaluate the effect of IPM use on perioperative outcomes and long-term survival in patients with HCC. METHODS: A systemic literature search was performed in the PubMed, Embase, Web of Science, and Cochrane Library databases to identify randomized controlled trials and retrospective studies that compared the effect of IPM with no Pringle maneuver during liver resection in patients with HCC. Hazard ratio (HR), risk ratio, standardized mean difference, and their 95% confidence interval (CI) values were calculated based on the type of variables. RESULTS: This meta-analysis included nine studies comprising one RCT and eight retrospective studies and involved a total of 3268 patients. Perioperative outcomes, including operation time, complications, and length of hospital stay, except for blood loss, were comparable between the two groups. After removing the studies that led to heterogeneity, the results showed that IPM was effective in reducing blood loss. Five studies reported overall survival (OS) and disease-free survival (DFS) data and eight studies reported perioperative outcomes. No significant difference in OS and DFS was observed between the two groups (OS: HR, 1.01; 95% CI, 0.85-1.20; p = 0.95; DFS: HR, 1.01; 95% CI, 0.88-1.17; p = 0.86). CONCLUSION: IPM is a useful technique to control blood loss during liver resection and does not affect the long-term survival of patients with HCC.

Multi-layer three-dimensionally ordered bismuth trioxide/titanium dioxide nanocomposite: synthesis and enhanced photocatalytic activity.

Taking polystyrene latex spheres (PS) and EO20PO70EO20 (P123) as dual templates, and TiO2 was used as substrate, a series of multi-layer three dimensionally ordered macroporous (3DOM) composites Bi2O3/TiO2 were successfully synthesized with sol-gel method and post-processing calcination. The fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), UV-vis diffuse reflectance (UV-vis/DRS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HR-TEM) and nitrogen adsorption-desorption measurements were employed to analyze the crystalline phase, chemical composition, morphology, and surface physicochemical properties of as-synthetized samples. The results showed that as-composites were provided with obvious crystalline phase structure and periodically highly uniform ordered macroporous structure with mesoporous walls; moreover, of which was multi-layer three dimensionally ordered structure. As a result of unique optical properties of Bi2O3 and composite material structural characteristic being propitious to reactant molecular transmission and diffusion, the photocatalytic activities of 3DOM Bi2O3/TiO2 were enhanced, and the sample 3DOM Bi2O3/TiO2-2 was significantly higher than that of direct photolysis, P25, Bi2O3, and other 3DOM Bi2O3/TiO2-X (X=1, 3, 4) during the photocatalytic degradation of crystal violet under multi-modes such as UV, visible light, simulated solar light, and microwave-assisted irradiation. The centrifugal samples water solution phase of TOC analysis indicated that water solution products formed with continued ultraviolet radiation, the intermediates eventually mineralized, volatilized, or were converted to other products. In addition, the photocatalytic activity of 3DOM Bi2O3/TiO2-2 composite was basically kept even after three cycles. Meanwhile, the possible photocatalytic reaction mechanism of as-synthesized material based on the experimental results was proposed.
