Background In Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. Thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private *** Between October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in Ha Noi, Hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate *** The pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578;P=0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313;P=0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164;P<0.001). This resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%;P=0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio [(aOR=13.71; 95% confidence interval (CI): 1.36–138.14;P=0.026], unemployment during treatment (aOR=10.86; 95%CI: 2.64–44.60;P<0.001) and experiencing TB-related stigma (aOR=37.90; 95%CI: 1.72–831.73;P=0.021).Conclusions Persons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the

This study aims to evaluate the effect of serum concentration, synchronization time, and confluence degree on the synchronisation efficiency of goat fibroblast cycle. The results indicated that there was no difference in the percentage of nucleated fibroblasts in the G0/G1 stage between serum concentrations of 0.3% and 0.4% (83.89% and 82.69%, respectively, P > 0.05) as well as between serum concentrations of 0.2% and 0.5% (76.95% and 75.46%, respectively, P > 0.05). The percentage of nucleated fibroblasts in the G0/G1 stage was highest at the concentration of 0.3% and lowest in the control group (83.89% vs. 62.67%, P 0.05). The beneficial effect of high confluence was confirmed by the large percentage of nucleated fibroblasts at the G0/G1 stage. The 60% confluency was significantly lower than the 80% and 100% confluency (73.44%, 86.63%, and 87.17%, respectively, P < 0.05). The results indicate that the goat fibroblast cycle synchronization is the most effective at the serum concentration of 0.3%, 72 hours of synchronization and 100% confluency.

随着互联网的不断发展,消费者偏好在不断变化。消费者偏好作为推动市场需求和购买决策的重要因素,对供应链决策具有深远的影响。消费者偏好的多样性和动态性成为供应链管理者及学者关注的核心问题。基于此,文中拟通过文献计量分析法,探讨消费者偏好视角下的供应链研究现状及趋势,拟以中国知网(CNKI)文献资料为基础,通过CiteSpace软件,从发文量、作者、机构和关键词等方面,对消费者偏好视角下的供应链研究领域进行可视化分析,并对当前的研究热点和今后的发展趋势进行归纳总结。研究发现,目前的研究呈现三大特点:一是研究主题主要涉及供应链的定价问题、协调问题和决策问题;二是消费者偏好种类不断变化;三是探讨的供应链类型逐渐增多。未来的研究可以在消费者偏好视角的基础上,围绕大数据驱动的数字化供应链问题、碳减排政策、供应链服务、供应链竞争等方面展开。

为探讨稻壳炭强化蚯蚓堆肥对污泥性质和重金属的影响,本研究以城市污泥为研究对象,添加不同比例稻壳炭对蚯蚓堆肥进行强化处理,探究不同生物炭剂量(污泥干质量的2%、4%、6%、8%)对城市污泥蚯蚓堆肥过程中重金属有效态以及赋存形态的影响。结果表明:堆肥过程中pH呈先上升后降低的趋势,电导率先降低后升高,有机质呈下降趋势;与对照组(不添加稻壳炭)相比,添加不同比例稻壳炭强化后的电导率、有机质分别降低28.96%~47.46%、2.84%~18.87%;稻壳炭强化的污泥堆肥中养分增加,总氮、总磷和总钾在8%添加量时分别提高9.89%、24.39%和2.51%。当稻壳炭添加到蚯蚓堆肥后,重金属从易迁移转化形态向稳定态转化,在8%添加比例时,Cd、Cu、Ni的残渣态占比较对照组分别提高3.57、19.12、9.27个百分点,有效态分别降低56.25%、34.22%、28.20%;添加4%稻壳炭使Pb由可交换态、碳酸盐结合态向稳定的有机结合态转化,且有效态降低27.69%。相关性分析发现稻壳炭强化蚯蚓堆肥,升高堆体pH降低了污泥中Cd、Cu、Ni、Pb有效态含量。研究表明,稻壳炭强化蚯蚓堆肥可显著提升城市污泥营养元素,改善理化性质,提高污泥中重金属钝化效率。
