The safety and efficacy of ultrasound-guided erector spinae plane block in postoperative analgesic of PCNL: A systematic review and meta-analysis.

BACKGROUND: The patients received percutaneous nephrolithotomy (PCNL) with severe postoperative pain and discomfort. The erector spinae plane block (ESPB), as a new anesthesia method of plane block, has a positive effect on postoperative analgesia. But evidence of ESPB in PCNL is still lacking. The objective of this study was to systematically analyze the postoperative analgesic effect of ESPB in patients receiving PCNL. METHODS: The literature searching was conducted in PubMed, EMBASE, Cochrane Library and Clinical Trial Database (clinicaltrials.gov). Two independent researchers screened the included studies and extracted data. Meta-analysis was conducted by using the random-effect model with 95% confidence intervals. Chi-squared test with a significance level of 0.1 was utilized to evaluate the heterogeneity of included studies. The subgroup analysis and meta-regression analysis were conducted in studies with high heterogeneity. The publication bias was assessed based on whether there were discrepancies between prospective trial registration and reported protocols. RESULTS: There were 8 studies involving 456 patients assessing the efficacy of ESPB in reducing postoperative pain score of PCNL compared with no block or other blocks, such as subcutaneous infiltration, general anesthesia or TPVB intrathecal morphine. ESPB was a significantly effective and safe anesthesia method, which not only improved postoperative pain response (MD -1.76; 95% CI -2.57 to -0.94; I 2 = 85%; p<0.01), but also reduced analgesic consumption (MD -16.92; 95% CI -26.25 to -7.59; I 2 = 92.2%; p<0.01) and prolonged the time of first request for postoperative analgesia (MD 93.27; 95% CI 35.79 to 150.75; I 2 = 85.3%; p = 0.001) in patients receiving PCNL without significant postoperative complications (MD 0.80; 95% CI 0.31 to 2.03; I 2 = 0%; p = 0.404). CONCLUSIONS: Compared with no block or other blocks, the ESPB was a safe and effective anesthesia for patients receiving PCNL.

A Series of Polymer-Supported Polyoxometalates as Heterogeneous Photocatalysts for Degradation of Organic Dye.

Photocatalytic degradation technology has developed rapidly in the treatment of organic pollutants due to its high efficiency, mild reaction conditions and easy control. In this paper, a series of heterogeneous photocatalysts, BWZ-en-R (BWZ = [BW11Z(H2O)O39]7-, Z = Zn, Cd, Mn, en = ethylenediamine, R = Merrifield resin), were prepared by using ethanediamine as a linker to immobilize Keggin-type transition elements substituting tungstoborates on Merrifield resin and characterized by Fourier transform infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The photocatalytic properties of BWZ-en-R (Z = Zn, Cd, Mn) for the degradation of methyl red (MR) were investigated. The results show that the BWZ-en-R (Z = Zn, Cd, Mn) photocatalysts exhibited high photodegradation ability for MR under the irradiation of ultraviolet light, and were easily separated from the reaction media. The maximum degradation rate (%) of MR (40 mL, 25 µM, pH = 2) reached 96.4% for the BWMn-en-R photocatalyst (40 mg) after being irradiated for 30 min, making this a promising photocatalyst candidate for dye degradation. Moreover, the influences of some factors, such as the Z-substituted elements in the BWZ, the BWZ-en-R dosage and the MR initial concentration, on the photocatalytic degradation rate of MR were also examined.

Using planned behavior theory to understand cervical cancer screening intentions in Chinese women.

Introduction: Cervical cancer is still one of the cancers threatening the health of Chinese women with high morbidity and mortality. However, the participation rate of cervical cancer screening (CCS) among women is low due to various reasons, so it is crucial to understand the factors that influence women's willingness to be screened for cervical cancer. This study's goal was to understand the intention of cervical cancer screening in Chinese women using the theory of planned behavior (TPB). Methods: An online questionnaire was administered to 286 women using a cross-sectional design. The questionnaire was created using the theory of planned behavior and included demographic characteristics as well as the basic structure of TPB. Results: Descriptive, correlation, and multiple linear regression models were performed to identify factors associated with cervical cancer screening behavior. 286 respondents completed the survey (95.3%). The mean scores for behavioral attitude, subjective norm and perceived behavioral control (PBC) were 32.50 (SD = 3.30), 22.59 (SD = 2.80) and 29.57 (SD = 3.37). From the regression analysis, behavioral attitude (B = 0.110, p = 0.001), subjective norm (B = 0.234, p = 0.000) and perceived behavioral control (B = 0.171, p = 0.000) were statistically significant in terms of intention. Discussion: This study provided a reference for improving the intention of cervical cancer screening in women.

Activities of Daily Living and Depression in Chinese Elderly of Nursing Homes: A Mediation Analysis.

Purpose: This study aimed to explore the role of sleep quality as a mediator in the activities of daily living (ADLs) and depression. Patients and Methods: Participants (N=645; age≥60) were included in six nursing homes in Weifang, Shandong Province, using convenience sampling. Participants completed questionnaires to assess sleep quality, ADLs, and depression. Depression condition was assessed by the Patient Health Questionnaire (PHQ-9), ADLs was assessed by the Barthel Index (BI), and sleep quality was measured by the Pittsburgh Sleep Quality Index (PSQI). Mediation analysis was carried out by SPSS PROCESS. Results: ADLs (r=0.449, P<0.01) and sleep quality (r=0.450, P<0.01) were found to be positively associated with depression among the elderly. Sleep quality plays a significant mediating role in the influence of ADLs on depression in the elderly in nursing homes (Bootstrap 95% CI [0.076, 0.139]), The pathway from ADLs to sleep quality to depression yielded a medium effect size of 20.23%. Conclusion: ADLs help to explain how sleep quality partly mediates depression among the elderly in nursing homes. It is therefore recommended that timely detection and efficient interventions should focus on promoting physical function and improving sleep quality among the elderly in nursing homes.

Depressive symptoms and physical function among the elderly in nursing homes during the COVID-19 pandemic in China: A cross-sectional study.

The coronavirus disease 2019 (COVID-19) pandemic has placed a heavy burden on global healthcare. Depressive symptoms and physical function impairment are 2 common health problems among the elderly, but the association between depressive symptoms and physical function in nursing homes have not been extensively investigated during the COVID-19 pandemic. The purpose of this study was to investigate the current status of depressive symptoms and physical function and analyze the prevalence and related factors of depression among elderly people in nursing homes during the COVID-19 pandemic in China. A cross-sectional study was conducted. 381 elderly people were included in 4 nursing homes who were 60 to 100 years old with more than 3 months' residential in Weifang City, Shandong Province using convenience cluster sampling. The Patient Health Questionnaire (PHQ-9) was performed to evaluate geriatric depression, the Barthel Index (BI) was administered to assess the activities of daily living, and a self-designed demographic data questionnaire was used to collect the demographic data. Multiple logistic regression analysis was conducted. 103 (27.0%) old residents reported depression according to PHQ-9. 279 (73.2%) old residents reported impaired self-care ability according to BI. The mean score of PHQ-9 and BI in the elderly was 3.56 ± 3.76 and 5.76 ± 7.05. The total PHQ-9 score of the elderly in nursing homes was positively correlated with the total activities of daily living score (R = 0.503, P < .01). Regression analysis showed that gender, self-care ability, more chronic diseases and medicines, especially Alzheimer's disease and cataract were risk factors for depression among elderly people in nursing homes (P < .05). Our study showed 27.0% depression rate among old residents in nursing homes in China in the context of the COVID-19 pandemic. Depression is relatively prevalent among the elderly in China, and we should pay attention to those with poor self-care ability and more chronic diseases and medicines.

Using Delphi method to develop Chinese women's cervical cancer screening intention scale based on planned behavior theory.

BACKGROUND: Cervical cancer is the most common malignant tumor in women with a high mortality rate. However, the awareness and participation of women in cervical cancer screening were not high, and rare attention was paid to cervical cancer screening. The extensive promotion and execution of cervical cancer screening in China are still facing difficulties. In order to fully comprehend and evaluate the barriers and promote factors of cervical cancer screening in women, the objective of this study was to develop a scientifically sound and clinically useful Chinese cervical cancer screening intention scale. This study would allow for the development of targeted interventions which may contribute to the increase of individual participation in cervical cancer screening going forward. METHODS: This study used the Delphi method to construct a Chinese cervical cancer screening intention scale based on the theory of planned behavior (TPB) and evaluate its validity. The study was based on the overview of the TPB questionnaire proposed by Ajzen, and was conducted through the literature search and two rounds of the Delphi expert consultation. According to the literature search published from 2012 to 2022, the scale item pool was established and a questionnaire was designed. A survey of 16 experts from 6 different provinces, cities and regions in China was conducted, and the Delphi technique was used to collect and analyze expert opinions data. RESULTS: The final scale consisted of 4 dimensions and 23 items. The response rates in two rounds of expert consultation were 80% and 93.75%, respectively, with authority coefficients of 0.928 and 0.930. Variation coefficients varied from 0.07 to 0.21. Dimensions included "attitude towards behavior", "subjective norm", "perceived behavioral control" and "behavioral intention". CONCLUSIONS: Women's cervical cancer screening intentions could be assessed with the scale, since it had high validity and reliability, as well as high authority and coordination, meanwhile affording explanations and improving the efficiency of interventions.

The effectiveness of massage interventions on procedural pain in neonates: A systematic review and meta-analysis.

BACKGROUND: The painful procedures experienced by neonates during hospitalization have short-term or long-term effects on neonates. While the limitations of previous interventions make it imperative to explore effective interventions that are readily available. This systematic review and meta-analysis was conducted to evaluate the safety and effectiveness of massage for pain management in neonates. METHODS: This systematic review was registered in PROSPER. PubMed, Embase, Cochrane Library, and the Clinical Trials Registry were searched to December 2021. Two reviewers independently carried out study selection, data extraction, bias risk assessment. Continuous data were analyzed by mean differences (MD). Dichotomous data were reported using relative risk. If at least two studies reported identical results by the same pain assessment tool, a meta-analysis was conducted using random effect model and inverse variance. RESULTS: Total 11 included studies involving 755 neonates investigated the effects of massage on neonatal pain response compared to standard care. The meta-analysis showed that massage could effectively improve pain response in neonates compared to standard care no matter whether neonatal infant pain scale (NIPS) or premature infant pain profile (PIPP) was used as an assessment tool. Besides, massage was also effective for crying duration, blood oxygen saturation both during and after the procedure, but non-effective for the variation of respiratory rate after the procedure, and heart rate both during and after the procedure. CONCLUSIONS: Massage may have a positive effect on pain relief of neonate, and rigorous trials are needed in the future to determine the most effective massage method.

Deep Subspace Mutual Learning for cancer subtypes prediction.

MOTIVATION: Precise prediction of cancer subtypes is of significant importance in cancer diagnosis and treatment. Disease etiology is complicated existing at different omics levels; hence integrative analysis provides a very effective way to improve our understanding of cancer. RESULTS: We propose a novel computational framework, named Deep Subspace Mutual Learning (DSML). DSML has the capability to simultaneously learn the subspace structures in each available omics data and in overall multi-omics data by adopting deep neural networks, which thereby facilitates the subtype's prediction via clustering on multi-level, single-level and partial-level omics data. Extensive experiments are performed in five different cancers on three levels of omics data from The Cancer Genome Atlas. The experimental analysis demonstrates that DSML delivers comparable or even better results than many state-of-the-art integrative methods. AVAILABILITY AND IMPLEMENTATION: An implementation and documentation of the DSML is publicly available at https://github.com/polytechnicXTT/Deep-Subspace-Mutual-Learning.git.

The correlation study on antimicrobial resistance and biofilm related genes in clinical isolates of Acinetobacter baumannii.

In recent years, the proportion of nosocomial infections caused by Acinetobacter baumannii (Ab) strains has increased significantly, and its resistance to antibiotics is rising. The resistance mechanisms of Ab are complex, which include the integron formation, inactivating or deactivating enzyme, outer membrane permeability, biofilm formation, drug exocytosis mechanism and so on. The biofilm formation by bacteria leads to high resistance and immune evasion ability. The aim of this study is to investigate the resistance and distribution patterns of Ab isolates, and the biofilm formation related genes in Ab isolates in our hospital.
