Purpose: Dignity is a basic human right that is related to psychological distress factors in patients with cancer such as depression and demoralization. Hence, the dignity issue is of great importance to healthcare professionals. The present study aimed to advise healthcare professionals regarding the related distress factors of dignity in patients with cancer by investigating its relationship with patients’ demographics, disease characteristics, and psychological distress. Methods: This was a cross-sectional study design. A convenience sample of 267 patients with cancer from a medical center was recruited into this study. Each patient completed demographics and disease characteristics questionnaires, the Patient Dignity Inventory Mandarin Version, the Demoralization Scale Mandarin Version (DS-MV), and the Patient Health Questionnaire-9 (PHQ-9). Data were analyzed with SPSS 22.0 software. Results: Dignity was significantly correlated with age, demoralization, and depression. Cancer patients aged 65 or above were more likely to have a lower sense of dignity. In the present study, the sensitivity and specificity of the Patient Dignity Inventory Mandarin Version for demoralization (DS-MVꠑ30) were 84.8% and 79.1% and for depression (PHQ-9ꠑ10) were 73.8% and 70.9% in patients with cancer with an aggregate score of 35 or above. Conclusions: Dignity is significantly correlated with personal demographic characteristics and psychoꠓlogical distress in patients with cancer. The results provide reference data for healthcare professionals to understand and enable dignity in patients with cancer and aid in the development of methods that promote their dignity

Yu-Chi Li,Yin-Hsun Feng,Hui-Ying Chiang,Shu-Ching Ma,Hsiu-Hung Wang 한국간호과학회 2020 Asian Nursing Research Vol.14 No.4

Purpose: The aim of the study was to determine the effectiveness of dignity therapy for end-of-lifepatients with cancer. Methods: This study used a quasi-experimental study design with a nonrandomized controlled trial. Dignity therapy was used as an intervention in the experimental group, and general visit was used in thecontrol group. Thirty end-of-life patients with cancer were recruited, with 16 in the experimental groupand 14 in the control group. Outcome variables were the participants' dignity, demoralization, anddepression. Measurements were taken at the following time points: pre-test (before intervention), posttest1 (the 7th day), and post-test 2 (the 14th day). The effectiveness of the intervention in the twogroups was analyzed using the generalized estimating equation, with the p value set to be less than .05. Results: After dignity therapy, the end-of-life patients with cancer reflected increased dignity significantly[b ¼ 37.08, standard error (SE) ¼ 7.43, Wald c2 ¼ 24.94, p < .001], whereas demoralization(b¼ 39.55, SE ¼ 6.42,Wald c2 ¼ 37.95, p < .001) and depression (b¼ 12.01, SE ¼ 2.17,Wald c2 ¼ 30.71,p < .001) were both reduced significantly. Conclusion: Clinical nurses could be adopting dignity therapy to relieve psychological distress andimprove spiritual need in end-of-life patients with cancer. Future studies might be expanded tolooking at patients vis- a-vis end-of-life patients without cancer to improve their psychologicaldistress. These results provide reference data for the care of end-of-life patients with cancer fornursing professionals.

Protective Factors of Demoralization among Cancer Patients in Taiwan: An Age-matched and Gender-matched Study

Yu-Chi Li,Chung-Han Ho,Hsiu-Hung Wang 한국간호과학회 2017 Asian Nursing Research Vol.11 No.3

Purpose: This study aimed to explore the protective factors of demoralization in cancer patients via investigation of cancer patients' demographic and disease characteristics. Methods: This was a cross-sectional descriptive study. We used a structured questionnaire, which contained items on demographic and disease characteristics, as well as the Demoralization Scale Mandarin Version (DS-MV), with a cutoff of 30 or more indicating high demoralization. Data were analyzed with age-matched and gender-matched conditional logistic regression analysis. For the study, 428 questionnaires were delivered and 411 were recovered. After being age-matched and gender-matched, 182 participants of high demoralization (DS-MV > 30) and low demoralization (DS-MV 30) were obtained respectively, for a total of 364 participants. Results: Cancer patients' demoralization was significantly related to family support (p = .019), education (p = .049), and monthly income (p = .001). Family support [odds ratio = 0.38; p = .028; 95% confidence interval (0.16, 0.91)] and monthly income [odds ratio = 0.49; p = .009; 95% confidence interval (0.29, 0.84)] were protective factors of demoralization in cancer patients. Conclusion: Early and appropriate demoralization assessment of cancer patients' demographic and disease characteristics is very important in clinical settings. Healthcare providers might regularly monitor demoralization in cancer patients, and develop related nursing care guidelines or treatment for demoralization in cancer patients. The study results can be a reference for healthcare providers who work with cancer patients.

Platelet-Derived Growth Factor Receptor-α Subunit Targeting Suppresses Metastasis in Advanced Thyroid Cancer In Vitro and In Vivo

Thyroid cancer is the most common endocrine malignancy. Patients with well-differentiated thyroid cancers, such as papillary and follicular cancers, have a favorable prognosis. However, poorly differentiated thyroid cancers, such as medullary, squamous and anaplastic advanced thyroid cancers, are very aggressive and insensitive to radioiodine treatment. Thus, novel therapies that attenuate metastasis are urgently needed. We found that both PDGFC and PDGFRA are predominantly expressed in thyroid cancers and that the survival rate is significantly lower in patients with high PDGFRA expression. This finding indicates the important role of PDGF/PDGFR signaling in thyroid cancer development. Next, we established a SW579 squamous thyroid cancer cell line with 95.6% PDGFRA gene insertion and deletions (indels) through CRISPR/Cas9. Protein and invasion analysis showed a dramatic loss in EMT marker expression and metastatic ability. Furthermore, xenograft tumors derived from PDGFRA geneedited SW579 cells exhibited a minor decrease in tumor growth. However, distant lung metastasis was completely abolished upon PDGFRA gene editing, implying that PDGFRA could be an effective target to inhibit distant metastasis in advanced thyroid cancers. To translate this finding to the clinic, we used the most relevant multikinase inhibitor, imatinib, to inhibit PDGFRA signaling. The results showed that imatinib significantly suppressed cell growth, induced cell cycle arrest and cell death in SW579 cells. Our developed noninvasive apoptosis detection sensor (NIADS) indicated that imatinib induced cell apoptosis through caspase-3 activation. In conclusion, we believe that developing a specific and selective targeted therapy for PDGFRA would effectively suppress PDGFRA-mediated cancer aggressiveness in advanced thyroid cancers.

Scrap iron packed in a Ti mesh cage as a sacrificial anode for electrochemical Cr(VI) reduction to treat electroplating wastewater

Ya, Vinh,Guillou, Esther Le,Chen, Yi-Ming,Yu, Jui-Hsuan,Choo, Kwang-Ho,Chuang, Sheng-Ming,Lee, Shou-Jen,Li, Chi-Wang Elsevier 2018 JOURNAL- TAIWAN INSTITUTE OF CHEMICAL ENGINEERS Vol.87 No.-

<P><B>Abstract</B></P> <P>A novel sacrificial anode comprised of scrap iron packed inside a cage made of titanium mesh was developed for Cr(VI) reduction. With electric currents applied, the surface passivation of scrap iron electrode could be avoided. Due to the large surface area with open structures provided, the applied current densities (1.18–3.54 mA/cm<SUP>2</SUP>) were low, resulting in low operating voltage and energy consumption. Complete Cr(VI) removal was achieved with electric currents applied, whereas only 20% of the Cr(VI) was removed without electricity. Direct Cr(VI) reduction on the iron surface was a dominant mechanism for the system operated at low (0.25 A) or no current. Acidic pH levels were more effective in Cr(VI) removal, due to more adsorption of Cr(VI) onto the precipitated Fe hydroxide. The trend in total Cr removal was almost the same as that of Cr(VI) removal, but time required to complete total Cr removal was extended. With intermittent electricity supply at a high electric current intensity, the energy consumption of the system was more efficient. Using scrap iron as a sacrificial anode under the intermittent current condition can save 72–77% of the total operational costs required by the conventional plate electrode.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A novel anode packed with scrap iron inside a Ti mesh was used for reducing Cr(VI). </LI> <LI> Electroplating wastewater containing Cr(VI) and Ni(II) was treated. </LI> <LI> Current intensity and initial pH affect the Cr(VI) reduction pattern significantly. </LI> <LI> Intermittent but high electric current supply saved 72–77% of the operating costs. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Copper recovery via polyelectrolyte enhanced ultrafiltration followed by dithionite based chemical reduction: Effects of solution pH and polyelectrolyte type

Chou, Yi-Hsuan,Choo, Kwang-Ho,Chen, Shiao-Shing,Yu, Jui-Hsuan,Peng, Ching-Yu,Li, Chi-Wang Elsevier 2018 Separation and purification technology Vol.198 No.-

<P><B>Abstract</B></P> <P>A chemical reduction process was proposed to recover copper from the retentate of polyelectrolyte enhanced ultrafiltration (PEUF). Three polyelectrolytes (PSS, PAA, and PEI) containing various functional groups and molecular weights were studied to explore their effects on the copper removal in PEUF and on the copper recovery by chemical reduction under various pH conditions. With PSS which contains sulfonic group, copper was removed reasonably well (ca. 75%) by PEUF even under acidic pH value of 3. With PAA which contains carboxylic group, copper removal was a bit low (∼60%) under pH 3.0 but increased substantially at pH 4.0. A branched PEI having amine group achieved the highest Cu removal of 94% at pH 3. The copper removal efficiency decreased slightly with increasing pH due to the high permeation of PEI through membrane.</P> <P>Chemical reduction achieved the complete copper recovery for solution containing PSS. The copper recovery efficiencies were more than 95% for PAA solution with pH values ranging from 3 to 9 at reaction time of one hour. For PEI, the recovery efficiencies ranged from 20 to 96% and were pH dependent. Aggregated and settled readily copper particles were produced by chemical reduction in PSS solution. XRD analysis identified cuprous oxide in all of the samples. Dependent of pH and polyelectrolytes, additional peaks matching those of elemental copper were identified. TGA analysis showed that solids produced from PSS and PAA systems contained no polyelectrolytes while solid collected from PEI system contained 32% of polyelectrolyte.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Polyelectrolytes with different functional groups and MW were applied in PEUF. </LI> <LI> Effects of polyelectrolytes and pH on the reduction of copper were studied. </LI> <LI> Both Cu<SUB>2</SUB>O and Cu<SUP>0</SUP> were identified by XRD analysis of solids obtained. </LI> </UL> </P>

Synthesis and application of cationic spherical polyelectrolyte brushes as retention and drainage aid in bleached eucalyptus kraft pulp

Yu Huang,Houbin Li,Xiongzhi Zhang,Kaiqiao Fu,Chi Huang,Shiju Yuan 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.31 No.-

In the present study, a series of cationic spherical polyelectrolyte brushes (CSPB), consisting of a silicacore and a shell of copolymer of acrylamide (AM) and [2-(methacryloyloxy)ethyl] trimethylammoniumchloride (METAC), were synthesized. Then a dual-component system which was composed of CSPB andanionic polyacrylamide (APAM) was used to improve the retention and drainage properties of bleachedeucalyptus kraft pulp and precipitated calcium carbonate (PCC). Comparative researches about retentionand drainage properties between CSPB/APAM system and cationic starch/APAM system wereundertaken as well. Results showed that further improvement in first-pass retention (FPR) of pulp,FPR of PCC and drainage time could be achieved by CSPB/APAM system. It was also found that increase ofshear intensity led to a decrease in retention efficiency, while it had no significant influence on drainagetime of pulp. However, due to the symmetrical or quasi-symmetrical spherical brush structure, CSPB stillshowed better retention efficiency than cationic starch under different turbulent conditions. Furthermore, the flocculation mechanism of the CSPB/APAM dual-component system was proposedin the paper.

Shu-Li Cheng,Fu-Chi Yang,Hsuan-Te Chu,Chia-Kuang Tsai,Shih-Chieh Ku,Yu-Ting Tseng,Ta-Chuan Yeh,Chih-Sung Liang 대한신경정신의학회 2020 PSYCHIATRY INVESTIGATION Vol.17 No.12

Objective Schizophrenia has been associated with dysfunction of the hypothalamic-pituitary-adrenal axis. Furthermore, alterations in neurotrophic factors might contribute to the pathogenesis of schizophrenia. We aimed to evaluate the effects of a simulated laughter intervention on the levels of cortisol and BDNF and to determine whether the effects associated with simulated laughter could be sustained after discontinuation of the intervention. Methods In this randomized controlled study, patients with schizophrenia according to DSM-IV clinical criteria were randomly assigned to receive either 8-week-long simulated laughter intervention (n=32) or treatment-as-usual group (control group, n=27). The serum levels of BDNF and cortisol were measured at baseline, week 8, and four weeks after discontinuation (week 12) of the intervention program. Results After an 8-week simulated laughter intervention, the laughter group had significantly higher levels of BDNF; however, four weeks after discontinuation of the intervention, the levels of BDNF significantly dropped. Interestingly, the levels of cortisol did not change significantly at week 8, but they were significantly elevated at week 12. The levels of BDNF and cortisol in the control group did not change significantly between week 0 and week 8. Conclusion These findings suggest that the simulated laughter intervention has an early effect on neurogenesis with a significant delayed effect on stress regulation in subjects with schizophrenia.
