RESUMO

Fenazaquin, a potent insecticide widely used to control phytophagous mites, has recently emerged as a potential solution for managing Varroa destructor mites in honeybees. However, the comprehensive impact of fenazaquin on honeybee health remains insufficiently understood. Our current study investigated the acute and chronic toxicity of fenazaquin to honeybee larvae, along with its influence on larval hemolymph metabolism and gut microbiota. Results showed that the acute median lethal dose (LD50) of fenazaquin for honeybee larvae was 1.786 µg/larva, and the chronic LD50 was 1.213 µg/larva. Although chronic exposure to low doses of fenazaquin exhibited no significant effect on larval development, increasing doses of fenazaquin resulted in significant increases in larval mortality, developmental time, and deformity rates. At the metabolic level, high doses of fenazaquin inhibited nucleotide, purine, and lipid metabolism pathways in the larval hemolymph, leading to energy metabolism disorders and physiological dysfunction. Furthermore, high doses of fenazaquin reduced gut microbial diversity and abundance, characterized by decreased relative abundance of functional gut bacterium Lactobacillus kunkeei and increased pathogenic bacterium Melissococcus plutonius. The disrupted gut microbiota, combined with the observed gut tissue damage, could potentially impair food digestion and nutrient absorption in the larvae. Our results provide valuable insights into the complex and diverse effects of fenazaquin on honeybee larvae, establishing an important theoretical basis for applying fenazaquin in beekeeping.

RESUMO

During home isolation due to the coronavirus disease, family caregivers assumed the responsibility of caring for infected family members; however, the full extent of the difficulties and challenges they encountered remains unclear. This study applied a descriptive phenomenology approach, using semi-structured, one-on-one, in-depth interviews to explore the experiences of 16 primary family caregivers during home isolation amid the coronavirus disease. The key themes identified were as follows: (1) protecting family, comprising anxiety over preventing infection and bearing the responsibility of caregiving and a concern about the diagnosis; (2) seeking stability, encompassing the impact of epidemic control policies on daily routines, strategies to overcome obstacles caused by quarantine measures, and gathering resources and receiving support; and (3) reflections on life, including favoring love over discrimination, rediscovering oneself, cherishing family, and acknowledging personal growth and dedication. This study highlights that family members who took on caregiving roles due to obstacles or health risks faced significant pressure to protect their family members during isolation and actively sought professional consultation and acquired caregiving skills to enhance their confidence and adaptability.

RESUMO

BACKGROUND: Patient safety culture is an indicator of healthcare quality and a topic of global importance in medical care. PURPOSE: In this study, the attitudes towards patient safety culture of nursing staff working in the emergency, intensive care, and general wards are compared before and during the COVID-19 pandemic. METHODS: A retrospective research design was utilized and an anonymous questionnaire survey conducted on the Taiwan Patient Safety Culture Survey web-based platform system was used to collect the data. The survey was administered in a regional hospital in northern Taiwan between 2018 and 2020. The 1,540 nursing personnel who participated in this study worked in the emergency, intensive care units, or general adult ward. The analysis focused on assessing participant attitudes towards patient safety culture in terms of both the overall score and sub-dimensions. RESULTS: The participants were mostly female and between 21 and 30 years old. A majority had completed a diploma or university education. The two analyses revealed the highest and lowest average scores were earned, respectively, in the "teamwork" and "resilience" dimensions of patient safety culture. In 2020, the average scores for all dimensions were lower than in 2018, and the average scores for the emergency and critical care group were lower than those for the general adult ward group. Sub-dimension analysis showed that the general adult ward group earned significantly higher scores in "teamwork" across all three sub-dimensions compared to the emergency and critical care groups. The general ward group exhibited the most significant score decline between the two surveys. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Overall scores were found to have decreased during the COVID-19 pandemic period (2020). Notably, emergency and intensive care nurses earned consistently lower scores, likely due to the severity of patient conditions and increased pandemic-related workloads and stress. "Resilience" scores were the lowest among all nursing staff, with the most significant drop seen in general ward nurses. Enhancing nursing staff education and training as well as addressing their psychological well-being will be crucial to improving patient safety culture attitudes. Managers should provide infection control, resilience training, and psychological counseling to help nurses manage the challenges posed by infectious diseases effectively and enhance patient safety culture.

RESUMO

BACKGROUND: The nature of the solid component of subsolid nodules (SSNs) can indicate tumor pathological invasiveness. However, preoperative solid component assessment still lacks a reference standard. METHODS: In this retrospective study, an AI algorithm was proposed for measuring the solid components ratio in SSNs, which was used to assess the diameter ratio (1D), area ratio (2D), and volume ratio (3D). The radiologist measured each SSN's consolidation to tumor ratio (CTR) twice, four weeks apart. The area under the receiver-operating characteristic (ROC) curve (AUC) was calculated for each method used to discriminate an Invasive Adenocarcinoma (IA) from a non-IA. The AUC and the time cost of each measurement were compared. Furthermore, we examined the consistency of measurements made by the radiologist on two separate occasions. RESULTS: A total of 379 patients (the primary dataset n = 278, the validation dataset n = 101) were included. In the primary dataset, compared to the manual approach (AUC: 0.697), the AI algorithm (AUC: 0.811) had better predictive performance (P =.0027) in measuring solid components ratio in 3D. Algorithm measurement in 3D had an AUC no inferior to 1D (AUC: 0.806) and 2D (AUC: 0.796). In the validation dataset, the AI 3D method also achieved superior diagnostic performance compared to the radiologist (AUC: 0.803 vs 0.682, P =.046). The two measurements of the CTR in the primary dataset, taken 4 weeks apart, have 7.9 % cases in poor consistency. The measurement time cost by the radiologist is about 60 times that of the AI algorithm (P <.001). CONCLUSION: The 3D measurement of solid components using AI, is an effective and objective approach to predict the pathological invasiveness of SSNs. It can be a preoperative interpretable indicator of pathological invasiveness in patients with lung adenocarcinoma.

RESUMO

BACKGROUND: Immunochemotherapy has become a new treatment for advanced esophageal squamous cell carcinoma (ESCC). AIMS: We aimed to study the clinical efficacy and toxicity of immunochemotherapy based on PD-1/PD-L1 compared with chemotherapy alone in the treatment of advanced ESCC, focusing on analyzing the influence of PD-L1 expression level. METHODS AND RESULTS: Five randomized controlled trials comparing PD-1/PD-L1 based immunochemotherapy with chemotherapy alone for advanced ESCC were included. We extracted efficacy data (objective response rate [ORR], disease control rate [DCR], overall survival [OS] rate, progression-free survival [PFS] rate) and safety data (treatment-related adverse events, treatment-related mortality) and performed meta-analyses. Compared with chemotherapy alone, the ORR and DCR of immunochemotherapy increased by 2.05 times and 1.54 times, respectively. Overall, patients receiving immunochemotherapy had a significant long-term survival advantage (OS: hazard ratio [HR] = 0.68, 95% confidence intervals [CI] 0.61-0.75; PFS: HR = 0.62, 95% CI 0.55, 0.70, respectively). Even with PD-L1 tumor proportion score <1%, immunochemotherapy also showed a significant survival advantage (OS: HR = 0.65, 95% CI 0.46-0.93; PFS: HR = 0.56, 95% CI 0.46-0.69, respectively). However, for PD-L1 combined positive score (CPS) < 1, the survival advantage of immunochemotherapy was not significant (OS: HR = 0.89, 95% CI 0.42-1.90; PFS: HR = 0.71, 95% CI 0.47-1.08, respectively). The toxicity of immunochemotherapy was higher than that of chemotherapy alone, but there was no statistical difference in treatment-related mortality (odds ratio = 1.11, 95% CI 0.67-1.83). CONCLUSION: In this study, treatment-related mortality was similar between immunochemotherapy and chemotherapy. PD-1/PD-L1 based immunochemotherapy significantly could improve survival outcomes in patients with advanced ESCC. For patients with CPS <1, the survival advantage of immunochemotherapy was not significant compared with chemotherapy.

RESUMO

A previous study found that the characteristic parameter σ2(k∙ECx) (the concentration ECx and slope k of the concentrationresponse curve (CRC) at the effect x %) can predict the acute combined toxicity of multiple mixtures with S-shaped CRCs. In this paper, the competence of σ2(k∙ECx) to predict the long-term toxicity of multiple mixtures with J-shaped CRCs was explored using the Aliivibrio fischeri as the test organism. The combined toxicity was evaluated by the independent action (IA) model and the effect ratio (ERx) model. The stepwise method was used to divide J-shaped CRC into ML and MR (SL and SR). The results showed that the σ2(k∙ECx) and ERx of each segment was in good agreement with the exponential function. A new type of mixture was added to the original type A and type B, whose rules of interaction were opposite to those of type B (named opposite B, OB). This paper improves the understanding and analysis of the J-shaped CRCs in environmental risk assessment.

RESUMO

Objective: The aim of this study was to investigate the effect of preoperative radiotherapy (RT) on overall survival (OS) in patients with stage cTxN0M0 esophageal squamous cell carcinoma (ESCC). Methods: A total of 467 patients with ESCC diagnosed as cTxN0M0 and undergoing esophagectomy between 2004 and 2016 were downloaded from the Surveillance, Epidemiology, and End Results (SEER) database. According to the presence or absence of preoperative RT, the patients were divided into preoperative RT group and non-preoperative RT group. Propensity score matching (PSM) was performed to equalize baseline levels between groups. Univariate and multivariate Cox regression analyses were used to compare the survival differences between the two groups. Results: Using PSM, 162 pairs of patients were selected. Preoperative RT was not a prognostic factor for OS in all patients with cTx stage. After PSM, for patients with cT1-2 stage, univariate Cox regression analysis showed that preoperative RT was an influencing factor of OS, and multivariate Cox regression analysis confirmed that preoperative RT was an independent predictor of OS. Compared with non-preoperative RT, preoperative RT significantly decreased OS (HR = 1.556, 95%CI 1.008-2.464, p = 0.046). For patients with cT3-4, univariate Cox regression analysis showed that preoperative RT was an influencing factor for OS, and multivariate Cox regression analysis determined that preoperative RT was independent predictors of survival. Compared with non-preoperative RT, preoperative RT significantly improved the OS (HR = 0.479, 95%CI 0.272-0.841, p = 0.010). Conclusion: For ESCC, preoperative RT can improve the OS of patients with cT3-4N0M0. However, preoperative RT is not suitable for patients with cT1-2N0M0.

RESUMO

OBJECTIVES: Neoadjuvant therapy and minimally invasive esophagectomy (MIE) are widely used in the comprehensive treatment of esophageal cancer. This study aimed to investigate the advantages of MIE for esophageal cancer after neoadjuvant therapy. METHODS: Published clinical studies were reviewed and survival data and safety data were extracted. We compared the long-term survival and safety of MIE versus open esophagectomy after neoadjuvant surgery in a series of meta-analyses. RESULTS: 6 retrospective studies were included. Overall, MIE could significantly improve the overall survival of patients with esophageal cancer after neoadjuvant therapy compared with open esophagectomy [hazard ratio (HR) = 0.86, 95% confidence interval (CI) (0.75, 0.98)]. Compared with open esophagectomy, MIE could significantly reduce intraoperative blood loss and operative time [mean difference (MD) = -40.28.78, 95% CI (- 62.98, - 17.58); MD = -28.78, 95% CI (- 42.48, - 15.07), respectively]. There was no significant difference in 30-day and 90-day mortality between MIE and open esophagectomy [odds ratio (OR) = 0.42, 95% CI (0.09, 2.01); OR 0.80, 95% CI (0.25, 2.60), respectively]. MIE could not significantly reduce the incidence of anastomotic leakage, recurrent laryngeal nerve palsy and chylothorax [OR 0.70, 95% CI (0.37, 1.32); OR 1.43, 95% CI (0.33, 6.25); HR = 1.79, 95% CI (0.67, 4.75), respectively], but the incidence of pneumonia was significantly reduced [HR = 0.43, 95% CI (0.22, 0.82)]. In addition, the length of hospital stay and the incidence of total complications were significantly reduced after MIE [MD = -2.61, 95% CI (- 3.10, - 2.12); HR = 0.66, 95% CI (0.45, 0.98), respectively]. CONCLUSION: MIE after neoadjuvant therapy is effective and safe. Compared with open esophagectomy, MIE can improve the long-term survival and reduce the incidence of postoperative complications of esophageal cancer patients.

RESUMO

BACKGROUND: According to the JCOG0802 study, there were many non-cancer-related deaths in the lobectomy group. Meanwhile, the median age of the enrolled patients in the JCOG0802 study was 67 years old. Whether this difference in perioperative outcomes and survival outcomes is related to age remains unknown. We aim to investigate whether the sublobectomy was comparable to lobectomy in elderly (≥ 75 years old) patients with peripheral solid-dominant [50% ≤ consolidation tumor ratio (CTR) ≤ 1] and diameter ≤ 2 cm non-small cell lung cancer (NSCLC). METHODS: We retrospectively included 10,830 patients who underwent surgery treatment at two large-volume medical centers, Taizhou Hospital of Zhejiang Province and Shanghai Chest Hospital, from January 2016 to January 2018. Of these, 164 patients aged ≥ 75 years, tumor ≤ 2 cm, and 50% ≤ CTR ≤ 1 who received lobectomy or sublobectomy were included in our study. The perioperative outcomes, survival analyses, analysis of death patterns, tumor recurrence patterns, and Cox regression analyses were performed. RESULTS: On perioperative outcomes, sublobectomy was associated with a shorter operation time (p < 0.001), and in terms of survival outcomes, the 5-year overall survival (OS, p = 0.85) and 5-year disease-free surivial (DFS, p = 0.58) did not differ significantly between the two groups. The Cox regression analyses showed that CTR value, visceral pleural infiltration, and smoking were independent risk factors for worse OS. Furthermore, tumor recurrence pattern and death patterns between the two groups did not differ significantly. CONCLUSIONS: Sublobectomy could achieve superior perioperative outcomes and equivalent oncological efficacy in comparison with lobectomy in elderly patients (≥ 75 years old) with peripheral solid-dominant and diameter ≤ 2 cm NSCLC.

RESUMO

OBJECTIVES: The prognosis of patients with locally advanced esophageal squamous cell carcinoma with different recurrence backgrounds is highly heterogeneous. This study aims to explore the effects of recurrence patterns on prognosis. METHODS: The phase III, multicenter, prospective NEOCRTEC5010 trial enrolled 451 patients with stage IIB-III esophageal squamous cell carcinoma randomly assigned to neoadjuvant chemoradiotherapy combined with surgery (NCRT group) or surgery alone (S group) and followed them long-term. We investigated the effects of recurrence patterns on survival in patients undergoing radical esophagectomy. RESULTS: In total, 353 patients were included in the study. The 5-year overall survival of patients with different recurrence patterns was significantly different: recurrence versus recurrence-free (17.8% vs 89.2%; P < .001), early recurrence versus late recurrence (4.6% vs 51.2%; P < .001), and distant metastasis versus locoregional recurrence (17.0% vs 20.0%; P = .666). Patients with early recurrence had significantly shorter survival after recurrence than those with late recurrence (hazard ratio, 1.541; 95% confidence interval, 1.047-2.268, P = .028). There was no significant difference in postrecurrence survival between patients with distant metastasis and locoregional recurrence (hazard ratio, 1.181; 95% confidence interval, 0.804-1.734; P = .396). Multivariate logistic analysis showed that pN1 stage, lymph node dissection <20, and lack of response to NCRT were independent risk factors for postoperative early recurrence. Multivariate Cox regression suggested that NCRT, age ≥60 years, early recurrence, and the pN1 stage were independent risk factors for shortened survival after recurrence. CONCLUSIONS: Prerecurrence primary tumor stage is inaccurate in predicting postrecurrence survival. In contrast, recurrence patterns can guide follow-up while also predicting postrecurrence survival. NCRT prolongs disease-free survival but is associated with a worse prognosis in patients with recurrence, especially early recurrence.

RESUMO

The concept of a public energy field is central to public administration discourse theory. Its main idea is the facilitation of dialog between government and the public, on the basis of equality, to construct a public policy consensus. In contemporary society, social media provides new and distinctive channels for such interactions. Social media can, therefore, be conceived as a novel type of public energy field. Since the outbreak of the COVID-19 pandemic, interactions between the Chinese government and the Chinese public (whether located in China or abroad) have been acutely reflected through WeChat official accounts. This article focuses on the COVID-19 pandemic and, through social media text mining and processing, analyzes the text topics and emotions covered. Basic principles of discourse validity, regarding this public energy field and two guarantee conditions, are applied to analyze the information exchange and dialog between the government and the public on COVID-19 through WeChat official accounts. It was found that the government's WeChat official accounts have not yet formed a harmonious dialog space to balance the public energy field, and that the interaction between the government and the public has to be improved. The government's social discourse had a significant influence on the public's social discourse. Using text analysis, the study found that the government has published information on 11 topics related to the prevention and control of the pandemic. It can be argued that the public energy field presented by both the government and the public effectively portrayed and reflected the actual situation of the pandemic in China.

RESUMO

Fluorous affinity chromatography has received growing attention in separation and purification of fluoro compounds, but the wettability of the fluorinated stationary phases is seldom noticed. Here, we construct a series of micro-sized fluorine-containing microspheres by solvothermal precipitation polymerization. The fluorinated microspheres could be obtained with narrow size distribution at even high monomer loading of 15 wt%. Through alternating fluoro monomer, both the particle size and the wettability of the microsphere array could be tuned. Among them, the poly(divinylbenzene -dodecafluoroheptyl methacrylate), P(DVB-DFHMA), microsphere (6.1 µm) arrays displays superhydrophobicity with 153.2° water contact angle. The P(DVB-DFHMA) fluorinated microspheres (7.58% fluorine content) can be packed into steel-less columns as stationary phase for high-performance liquid chromatography. The retention mechanism of the fluorinated column is proven to be the specific fluorine-fluorine interaction. Compared to the commercial C18 silica column, the fluorinated column can completely separate fluorine-containing compounds under high water content mobile phase, including small fluoro molecules and fluoro macromolecules, at much lower back pressure by fluorous affinity.

RESUMO

A previous acute toxicity study of binary mixtures showed that the combined toxicity can be predicted with the parameter k∙ECx. To systematically investigate the ability of k∙ECx to predict the chronic combined toxicity of binary mixtures, the toxicity of six contaminants and five binary mixtures was determined by long-term microplate toxicity analysis (L-MTA) using Aliivibrio fischeri as the test organism. The independent action model (IA) and the relative model deviation ratio (rMDR) were employed to determine the relationship between the Δ(k∙ECx)% and rMDRx. The results showed that these two factors conformed to the exponential function in long-term toxicity. Owing to the time-dependence of toxicity, the mixture type of chronic toxicity changes to the relative type of acute toxicity. If the acute toxicity of binary mixtures changes their mode of joint action throughout the concentration range, the chronic toxicity will also change their mode of joint action, and vice versa. This study clarified the change rules of the joint action of binary mixtures in acute and chronic toxicity which can promote research on chronic toxicity of binary mixtures.

RESUMO

Lung cancer has some of the highest morbidity and mortality rates of all cancers, and an important risk factor for mortality in patients with lung cancer is tumor metastasis. Even if a tumor is completely removed at an early stage of the disease, quite a number of patients still have the risk of recurrence. With the advent of molecular diagnostic and therapeutics, more and more studies have found that a poor prognosis may be related to lymph node micrometastasis. However, clinicians still find that predicting the prognosis and choosing the type of surgery and postoperative adjuvant chemotherapy are still challenging. Thus, this article reviews the current research status of lymph node micrometastasis in non-small cell lung cancer, envision to provide some updates and insights in this area.

RESUMO

This article considers impacts from innovation, defined in terms of research and development expenditure, on carbon emissions. We relate our study to scholarship about the Environmental Kuznets Curve and the Pollution Haven Hypothesis, situating this analysis within literature about the compatibility of broadly capitalist systems and combating climate change. We thus incorporate scholarship surrounding themes such as climate capitalism and ecological modernization. There are three main research questions. First, what is the impact of increasing levels of innovation on emissions? Second, how does the level of economic development affect impacts from greater innovation on emissions? Third, does this analysis generate evidence to support the Pollution Haven Hypothesis? To test these questions, and three parallel hypotheses, we initially deployed a panel data model, based on World Bank data, incorporating control variables covering economic, spatial and environmental factors. We then split the country sample into two GDP-based cohorts to test for variations in effects related to economic development. Subsequently, a multi-input regional-output model was deployed to incorporate analysis of a pollution haven effect. Our analysis suggests that whilst greater innovation diminished carbon dioxide emissions for high-income countries, this effect could not be identified elsewhere. Furthermore, the multi-input regional-output model implied that explanations for these contrasting results might lie in a pollution haven effect. Overall, this study implied some acutely limited support for climate capitalism and ecological modernization, constructed on data from high-income countries alone.

RESUMO

A previous study has revealed that the parameter k∙ECx, characterizing the shape of concentration-response curves (CRCs), could predict the combined toxicity of binary mixtures. This study further explored the predictability of multi-component mixtures. Eleven component mixtures were designed using the uniform design ray, and the acute toxicity of the eleven environmental pollutants and their mixtures to Vibrio fischeri was determined using microplate toxicity analysis. We used independent action (IA) and the effect residual ratio (ERRx) models to evaluate the combined toxicity of multi-component mixtures and ascertain the functional relationship between σ2(k∙ECx), a parameter characterizing the CRC morphological difference of multi-component mixtures, and combined toxicity. The variance σ2(k∙ECx) of each component characteristic parameter of multi-component mixtures gradually increased in the concentration range, and the relationship between σ2(k∙ECx) and ERRx was consistent with the exponential function. The literature verification showed that this rule is generally applicable to the acute toxicity of multi-component mixtures to luminescent bacteria. The exponential function showed the variation rule of the joint action of multi-component mixtures. In the present study, the joint toxicity of multi-component mixtures can be predicted from single toxicity and small amount of multiple toxicity, circumventing complex multi-component toxicity experiments.

RESUMO

The majority of pregnant women in Taiwan are not considered physically active. During pregnancy, many women decrease their physical activity levels when compared to pre-pregnancy. The purpose of this study was to examine the association between decreased physical activity from pre-pregnancy to pregnancy and excessive gestational weight gain (GWG). This study applied a prospective panel design. Recruitment was conducted at six medical facilities in Taiwan and lasted from August 2016 to April 2017. Physical activity levels were determined both before and during pregnancy using the International Physical Activity Questionnaire-Short Form, with data subsequently being transformed into METs-min/week. Excessive GWG was determined based on the body mass index (BMI) specific GWG range. We recruited 747 pregnant women in their second trimester and followed them through to one-month postpartum. About 40% of participants (41.2%) exhibited excessive GWG. Physical activity decreased from an average of 2261 (SD = 3999) to 1252 (SD = 2258) METs-min/week from pre-pregnancy to pregnancy (p < 0.0001). Controlling for age and pre-pregnancy BMI, a logistic regression model revealed that a decline in physical activity of > 4000 METs-min/week from pre-pregnancy to pregnancy was associated with an increased risk for excessive GWG (OR = 2.83, 95% CI: 1.27-4.43). A substantial decrease in physical activity from pre-pregnancy to pregnancy was a risk factor for excessive GWG. Although most women decreased their physical activity during pregnancy, only those pregnant women who were physically active pre-pregnancy could show the kind of large decrease that resulted in excessive GWG. Health professionals should continue to develop strategies for counteracting the problematic trend of decreasing PA during pregnancy among low-risk pregnant women.

RESUMO

The COVID-19 pandemic has significantly impacted everyone's lives, challenging us in ways that can be frustrating, daunting, and intensely emotive. This qualitative study explored the isolation experiences of patients with COVID-19 in a hospital in northern Taiwan. We collected data from nine patients in June-July 2020, conducting semi-structured, virtual face-to-face, in-depth interviews to gather input on two topics: (1) the psychological effect of hospital isolation on patients, including the psychological burden, stress response, support, disease stigma, and fear of returning to society; and (2) the patients' cognition and behaviors, which included tracking epidemic information, monitoring disease progression, soliciting suggestions about hospital isolation, and gauging comprehension after recovery. The results confirmed that hospital isolation significantly impacts patients physically, psychologically, spiritually, and socially. Thus, the isolated patients faced the dual challenges of fighting, adapting to, and recovering from the disease itself and struggling in isolation to maintain positive beliefs, independently assess their condition, and gain strength from the knowledge of continuing social support.
