Assessing the current situation and the influencing factors affecting perceived stigma among older patients after leukemia diagnosis

BACKGROUND Psychological problems are becoming increasingly prominent among older patients with leukemia,with patients potentially facing stigmatization after diagnosis.However,there is limited research on the stigma experienced by these patients and the factors that may contribute to it.AIM To investigate the stigma faced by older patients after being diagnosed with leukemia and to analyze the potential influencing factors.METHODS A retrospective analysis was conducted using clinical data obtained from questionnaire surveys,interviews,and the medical records of older patients with leukemia admitted to the Hengyang Medical School from June 2020 to June 2023.The data obtained included participants’basic demographic information,medical history,leukemia type,family history of leukemia,average monthly family income,pension,and tendency to conceal illness.The Chinese versions of the Social Impact Scale(SIS),Perceived Social Support Scale(PSSS),Self-Rating Anxiety Scale(SAS),and Self-Rating Depression Scale(SDS)were used to assess indicators related to stigma,social support,and mental health status.We used Pearson’s correlation coefficient to analyze the strength and direction of the relationship between the scores of each scale,and regression analysis to explore the factors related to the stigma of older patients with leukemia after diagnosis.RESULTS Data from 120 patients with leukemia aged 65-80 years were analyzed.The total score on the SIS and PSSS was 43.60±4.07 and 37.06±2.87,respectively.The SAS score was 58.35±8.32 and the SDS score was 60.58±5.97.The stigma experienced by older leukemia patients was negatively correlated with social support(r=-0.691,P<0.05)and positively correlated with anxiety and depression(r=0.506,0.382,P<0.05).Age,education level,smoking status,average monthly family income,pension,and tendency to conceal illness were significantly associated with the participants’level of stigma(P<0.05).Age,smoking status,social support,anxiety,and depression were predictive factors of stigmatization among older leukemia patients after diagnosis(all P<0.05),with a coefficient of determination(R2)of 0.644 and an adjusted R2 of 0.607.CONCLUSION Older patients commonly experience stigmatization after being diagnosed with leukemia.Factors such as age,smoking status,social support,and psychological well-being may influence older patients’reported experience of stigma.

Living experience and care needs of Chinese empty-nest elderly people in urban communities in Beijing,China:A qualitative study

Background:Empty-nest elders have considerable needs for daily living,health care,and social support in China.The growing need for care of an aging population requires to be met through adequate policy decision making by government.Aim:To explore care needs of Chinese empty-nest elderly people and to provide reference information for relevant authorities in making care-supporting policies.Method:A descriptive qualitative study design was adopted.Twenty-five senior citizens in urban communities who were not living with their children were recruited from three communities in different districts of Beijing.In-depth interviews with a semi-structured questionnaire were used to collect data.A qualitative content analysis method was used to analyze data.Results:A major care need by the empty-nest elderly was home-based care.In view of their physical condition,need of support and their own security problems,they would like to have aging-in-place,home-based care by housemaid employment,or have institutionalized care in the future.However,they had some concerns about institutionalized care.Conclusions:A combination of home-based and community-based care is a suitable mode of care for the empty-nest elderly,and institutionalized care is an expected supplementary form of care.

Highly efficient cobalt-based amorphous catalyst for peroxymonosulfate activation toward wastewater remediation

Metallic glasses(MGs)are rising novae in the catalytic field,due to their unique amorphous structure,large residual stress,and high density of low coordination sites.However,there is still an absence of suitable MGs'catalysts for advanced oxidation processes(AOPs)with peroxymonosulfate(PMS),the most efficient and promising wastewater remediation technology.Herein,the cobalt-based MG(Co-MG)with a nominal composition of Co_(67)Fe_(4)-Mo_(1.5)Si_(16.5)B_(11)(at%)was utilized as an activator of PMS for azo dye degradation.The results demonstrated that the CoMG/PMS system had an order of magnitude higher efficiency on OrangeⅡ(OII)degradation than the Fe-MG/PMS system.For fundamental study and field application,the effect of adding inorganic anions(Cl^(-),HCO_(3)^(-),H_(2)PO_(4)^(-),SO_(4)^(2-),NO_(3)^(-)),environmental factors,and cycle experiments on the catalytic properties of Co-MG were investigated emphatically to evaluate overall degradation performance.It has demonstrated that the Co-MG with more stability,better corrosion resistance and durability contrasted to Fe-MGs.In addition,the excellent catalytic performance of Co-MG was analyzed based on the quenched experiment,electron paramagnetic resonance(EPR),and X-ray photoelectron spectroscopy(XPS)analysis.The present results provide not only a new candidate but also shed light on exploring a new kind of AOPs system based on Co-MGs for wastewater treatment.

Fe-based metallic glass as heterogeneous Fenton-like catalyst for azo dyes degradation:effect of inorganic anions

Metallic glasses(MGs) are promising heterogeneous catalysts in water remediation,due to their superior efficiency,selectivity,reusability and corrosion resistance.However,few works are focused on the influence of inorganic anions that are abundant in wastewater.Herein,four common inorganic anions were added in a heterogeneous Fenton-like system(Fe-MG/H_(2)O_(2)) to study inorganic anions' influence on MGs' catalytic performance during methylene blue(MB) degradation.Evidence demonstrated that chloride ions and dihydrogen phosphate ions had an adverse effect on the catalytic performance of Fe-MG,whereas Fe-MG/H_(2)O_(2) system sustained high efficiency in the presence of sulfate ions and nitrate ions during the Fenton-like process.By studying the structure,surface morphology,and evolution of active species,it was found that inorganic anions had a significant effect on the surface morphology of Fe-MG and the generation of active species.This work will provide essential references for MGs as heterogeneous catalysts in practical applications.

纳米尺度非均匀性诱导自更新铁基非晶合金具有优异的长期反应活性（英文）

铁基非晶合金作为亚稳态新型零价铁,具有高活性亚稳态结构、较大的残余应力和高密度低配位点等特性,在催化和废水处理中引起了广泛的关注;但由于腐蚀产物沉淀覆盖活性位点,非晶合金的反应活性随着时间的推移而逐渐降低,导致耐用性差.腐蚀产物沉淀造成长期反应活性降低也是阻碍传统晶态零价铁技术在废水处理领域应用的主要问题之一.本文通过在铁基非晶合金中引入纳米尺度的化学不均匀性,有助于构成局部原电池效应,加速电子在降解过程中的转移,可以有效地克服这一问题.更重要的是,非晶合金中的零价铁被选择性腐蚀/脱合金,导致反应区域局部体积收缩和裂纹形成,裂纹扩展使沉淀腐蚀产物和反应区域自剥落.因此,可以连续提供新的低配位,消除质量传递和反应活性恶化的问题.本文所制备的具有成分不均匀的铁基非晶合金即使在中性溶液中也具有良好的长期反应活性和自更新性能.研究结果不仅为废水处理提供了一种新材料,而且为设计高活性零价铁材料提供了一种新思路.

Fe-based multi-phase nanocrystalline ribbons with hierarchically flowerlike structured metal oxides after modified by Orange II for Cr^VI absorption

Three-dimensional flowerlike nanostructured metal oxides attached on the surfaces of Fe-based multi-phase nanocrys- talline ribbons （Fe-MNRs） were prepared by a simple way （through immersing the Fe-MNRs in Orange II solution）. It has been found that the as-prepared Fe-MNRs with 3D flowerlike nanostructures （Fe-MNRs ＋ FNs） exhibit good absorption property for a typical heavy metal ion （Cr^VI） in wastewater, while Fe-MNRs do not possess such properties. The Fe-MNRs ＋ FNs could remove 99% CrvI ions from the solution in 40 min, and this adsorption property can be attributed to the ion exchange between Cr^VI and surface hydroxyl groups （O-H） of 3D flowerlike nanostructures. The present result suggests that the Fe-MNRs ＋ FNs, prepared by facile way, possess great potentials in removing heavy metallic ions in wastewater.
