RESUMEN

Terrestrial plants emit volatiles into the atmosphere to attract both pollinators and the enemies of herbivores, for defense. Phalaenopsis bellina is a scented orchid species in which the main scent components are monoterpenes, including linalool and geraniol, and their derivatives. Here, we investigated whether ABC transporters are involved in floral scent emission. We carried out whole-genome identification of ABC transporter-related genes using four floral transcriptomics libraries of P. bellina. We identified 86 ABC subfamily G genes related to terpenoid transport. After comparing the gene expression patterns of P. bellina with that of Phalaenopsis aphrodite subsp. formosana, a scentless species, followed by gene-to-gene correlation analysis, PbABCG1 and PbABCG2 were selected. The temporal expression of both PbABCG1 and PbABCG2 was highly correlated with that of the key enzyme PbGDPS and the major transcription factor PbbHLH4 in monoterpene biosynthesis, with optimal expression on day 5 post-anthesis. Spatial gene expression analysis showed that PbABCG1 was highly expressed in sepals, whereas PbABCG2 was expressed in the lip. Subcellular localization with a GFP fusion protein revealed that both PbABCG1 and PbABCG2 are cytoplasmic membrane proteins. Co-downregulation of PbABCG1 and PbABCG2 using both double-strand RNA interference and tobacco rattle virus-based gene silencing led to a significant decrease in monoterpene emission, accompanied by an increase in the internal monoterpene pools. Furthermore, ectopic expression of PbABCG1 and PbABCG2 in an ABC16- mutant yeast strain rescued its tolerance to geraniol. Altogether, our results indicate that PbABCG1 and PbABCG2 play substantial roles in monoterpene transport/emission in P. bellina floral scent.

RESUMEN

PURPOSE: Head and neck cancer (HNC) patients often suffer from shame and stigma due to treatment limitations or due to societal factors. The purpose of this study was to assess perceived body image, depression, physical and psychosocial function, and self-stigma, as well as to identify factors that predicted shame and stigma in patients with HNC. METHODS: This cross-sectional study recruited 178 HNC patients from the outpatient radiation department of a medical center in Northern Taiwan. Patients were assessed for patient reported outcomes using the Body Image Scale (BIS), the Hospital Anxiety and Depression Scale-Depression Subscale (HADS-Depression Subscale), the University of Washington Quality of Life Scale (UW-QOL) version 4.0, and the Shame and Stigma Scale (SSS). Data were analyzed by descriptive analysis, Pearson's product-moment correlation, and multiple regression. RESULTS: The two top-ranked subscales of shame and stigma were: "speech and social concerns" and "regret". Shame and stigma were positively correlated with a longer time since completion of treatment, more body image concerns, and higher levels of depression. They were negatively correlated with being male and having lower physical function. Multiple regression analysis showed that female gender, a longer time since completing treatment, higher levels of body image concern, greater depression, and less physical function predicted greater shame and stigma. These factors explained 74.7% of the variance in shame and stigma. CONCLUSION: Patients' body image concerns, depression, time since completing treatment, and physical function are associated with shame and stigma. Oncology nurses should assess and record psychological status, provide available resources, and refer appropriate HNC patients to counselling.

RESUMEN

BACKGROUND: Alzheimer's disease (AD) is the most common neurodegenerative disorder with clinical presentations of progressive cognitive and memory deterioration. The pathologic hallmarks of AD include tau neurofibrillary tangles and amyloid plaque depositions in the hippocampus and associated neocortex. The neuronal aggregated tau observed in AD cells suggests that the protein folding problem is a major cause of AD. J-domain-containing proteins (JDPs) are the largest family of cochaperones, which play a vital role in specifying and directing HSP70 chaperone functions. JDPs bind substrates and deliver them to HSP70. The association of JDP and HSP70 opens the substrate-binding domain of HSP70 to help the loading of the clients. However, in the initial HSP70 cycle, which JDP delivers tau to the HSP70 system in neuronal cells remains unclear. RESULTS: We screened the requirement of a diverse panel of JDPs for preventing tau aggregation in the human neuroblastoma cell line SH-SY5Y by a filter retardation method. Interestingly, knockdown of DNAJB6, one of the JDPs, displayed tau aggregation and overexpression of DNAJB6b, one of the isoforms generated from the DNAJB6 gene by alternative splicing, reduced tau aggregation. Further, the tau bimolecular fluorescence complementation assay confirmed the DNAJB6b-dependent tau clearance. The co-immunoprecipitation and the proximity ligation assay demonstrated the protein-protein interaction between tau and the chaperone-cochaperone complex. The J-domain of DNAJB6b was critical for preventing tau aggregation. Moreover, reduced DNAJB6 expression and increased tau aggregation were detected in an age-dependent manner in immunohistochemical analysis of the hippocampus tissues of a mouse model of tau pathology. CONCLUSIONS: In summary, downregulation of DNAJB6b increases the insoluble form of tau, while overexpression of DNAJB6b reduces tau aggregation. Moreover, DNAJB6b associates with tau. Therefore, this study reveals that DNAJB6b is a direct sensor for its client tau in the HSP70 folding system in neuronal cells, thus helping to prevent AD.

RESUMEN

PURPOSE: Spousal caregiving of head and neck cancer (HNC) patients challenges relationship quality and may negatively impact family function. Our purpose was to identify factors associated with family dysfunction in spousal caregivers (SCs) of HNC patients within the first 6 months after treatment. We explored whether patient or SC characteristics differ by level of family dysfunction. METHODS: We conducted a cross-sectional study of HNC patient-SC dyads in Taiwan from July 2020 to January 2022 using patient-reported outcomes. Patients were assessed using a set of structured questionnaires to measure performance status, demographic and clinical characteristics, physical function, and social-emotional function. SCs were measured on their hardiness, coping styles, spousal relationship, quality of life, and family function. RESULTS: Of the 132 dyads surveyed, 62.1% of SCs reported a functional family, 34.8% reported a moderately dysfunctional family, and 3.0% reported a highly dysfunctional family. Patient factors associated with family dysfunction (highly dysfunctional or moderately dysfunctional) included lower family annual income and worse social-emotional function. Associated SC factors were lower hardiness, less use of active coping, and worse spousal relationships. CONCLUSIONS: Lower family annual income, less patient social-emotional function, less SC hardiness, less SC active coping, and worse SC perceived spousal relationship were associated with perceived family dysfunction. Providing patient-SC dyads with sufficient social resources and problem-solving training may help them positively cope with cancer and enhance family function.

RESUMEN

PURPOSE: To identify factors associated with posttraumatic growth (PTG) of head-and-neck cancer squamous cancer (HNC) patients with oncologic emergencies (OE) within the first six months post-treatment. METHODS: We conducted a cross-sectional study of HNC patients in Taiwan from May 2019 to April 2021 using patient-reported outcomes. Patients were assessed for symptom distress, anxiety, fear of recurrence (FCR), and PTG. Multiple regression analysis was conducted to identify factors associated with PTG. The independent-samples t-test was used to compare PTG and its five specific domains in patients with low FCR, high FCR, low anxiety, and high anxiety. RESULTS: Of the 114 patients surveyed, 46.5% reported little-to-no PTG, and 53.5% had moderate-to-high PTG. Greater PTG was associated with greater FCR, longer time since OE, less anxiety, having a cancer recurrence, and greater educational attainment. These factors explained 38.6% of the variance in PTG. CONCLUSION: A notable proportion of HNC patients with OE-reported PTG but almost half-reported little-to-no PTG. PTG occurred most in the domain of appreciation of life. The study results also suggest that training patients in coping skills and inviting them to group growth experiences can help them increase PTG and cope with cancer-related psychological threats related to OE.

RESUMEN

PURPOSE: After suddenly stopping smoking after an initial oral cancer (OC) diagnosis, patients may restart smoking and nicotine dependence. This study sought to identify factors associated with high nicotine dependence in OC patients who restarted smoking post-treatment. DESIGN: A cross-sectional study. METHODS: A group of 220 OC patients who restarted smoking post-treatment were recruited from the outpatient radiation department of a single cancer center in northern Taiwan. Demographic and clinical characteristics were recorded, and patients were assessed for nicotine and smoking dependence, physical activity and function, socio-emotional function, social support, and depression. RESULTS: Among patients who restarted smoking after treatment for OC, 75.9% reported low-to-moderate dependence on smoking, while 24.1% reported high nicotine dependence. Factors associated with high nicotine dependence included higher incidence of smoking per day, greater dependence on smoking, less physical activity per week, and poorer social-emotional function. Those highly dependent on nicotine were younger, unmarried, had less education, and had begun smoking earlier than those with low-to-moderate nicotine dependence. CONCLUSIONS: The amount of smoking per day, greater smoking behavioral dependence, less physical activity per week, and worse social-emotional function affected high nicotine dependence. CLINICAL RELEVANCE: Smoking cessation training and counseling for OC patients may help them better control their use of tobacco after treatment.

RESUMEN

PURPOSE: Primary caregivers (PC) of patients with advanced head and neck cancer (HNC) report stress during caregiving time post-treatment. We sought to identify the trajectories of resilience from initial completion of treatment to 1-year post-treatment in PC of patients with advanced HNC and to determine the factors associated with trajectories of resilience. DESIGN: In this prospective cohort study with convenience sampling, patient-PC dyads were recruited from a medical center in northern Taiwan between August 2015 and July 2020. METHODS: We recruited 120 patient-PC dyads and followed up at treatment completion and 1, 6, and 12 months post-treatment. Generalized estimating equation analysis was performed to identified factors related to resilience. FINDINGS: PCs' overall resilience increased from initial completion of treatment to peak at 1-year post-treatment. Patient factors associated with greater overall resilience included older age, higher performance status, and shorter time since cancer diagnosis; PC factors included reporting more social support, better physical health, and better mental health. CONCLUSIONS: PC mental health was the most important factor in the resilience trajectory of patients with advanced HNC cancer. CLINICAL RELEVANCE: Quantifying the relevant factors of trajectories of resilience will help to identify vulnerable PCs and guide survivorship care in the early stages of the post-treatment period.

RESUMEN

PURPOSE: Oral dysfunction is a common adverse event of treatment and may affect oral health-related quality of life (OHRQoL). This study aimed to identify factors associated with OHRQoL in patients with oral squamous cell carcinoma (OSCC) within the first three months posttreatment. METHODS: This cross-sectional study examined OSCC patients who received treatment from the outpatient radiation department of a single cancer center in northern Taiwan. Demographic and clinical characteristics were recorded, and patients were assessed using the Self-Care Behaviors Scale (SCB), Oral Health Impact Profile (OHIP), and Karnofsky Performance Status (KPS) questionnaires. RESULTS: Among 148 OSCC patients, 11.5% reported being underweight and 70.3% reported normal weight. The most common self-care factors associated with adverse effects were decreased appetite and fatigue. Psychological disability, functional limitation, and physical pain were the most negative OHRQoL factors. Poor OHRQoL was associated with more severe adverse effects after self-care behaviors, using feeding tubes during treatment, and having BMI less than 25, which together explained 33.5% of the variance in OHRQoL. CONCLUSIONS: The severity of adverse effects after self-care behaviors and using feeding tubes during treatment strongly influenced overall OHRQoL and seven specific dimensions of OHRQoL.

RESUMEN

OBJECTIVES: This study investigates the relationship between multidisciplinary team care (MDTC) and patient completion of their treatment regimen for oral squamous cell carcinoma (OSCC). METHODS: We conducted a retrospective cohort study in patients diagnosed with OSCC in Taiwan from 1 January 2016 to 30 June 2018 using a linked cancer registry database. RESULTS: Of the 969 OSCC MDTC patients in the study cohort, 6.3% reported incomplete treatment, with 1.3% interrupting ongoing treatment and 5.0% terminating definitive treatment. Patients who had advanced-stage disease, experienced primary cancer recurrence or a secondary cancer, or were treated with surgery combined with chemotherapy, radiotherapy or chemoradiotherapy were more likely to terminate treatment before completion. The major reasons for interruption of ongoing treatment included 'patient or their family considered the patient to be in poor physical condition' and 'difficulty enduring physical discomfort caused by treatment'. The major reason for termination of definitive treatment was 'patient or their families or friends experienced negative treatment effects and worried about the side-effects of treatment'. CONCLUSION: Advanced-stage cancer, recurrence or secondary cancer, and surgery combined with chemotherapy, radiotherapy or chemoradiotherapy negatively affected treatment completion. MDTC allows for shared decision-making to determine the optimal treatment.

RESUMEN

The gastrointestinal dysfunction and nutrient malabsorption associated with gastrointestinal tumors and related treatments may result in malnutrition in gastrointestinal (GI) cancer patients. Malnutrition has been associated with decreased treatment tolerance, poor quality of life, and increased mortality in this patient population. In this article, the relevant literature is reviewed and the factors, assessment tools, and management strategies related to malnutrition are summarized. In clinical care, healthcare providers should conduct early assessments of nutritional status and provide individualization nutritional counselling to promote treatment that effectively prolongs patient survival. This article may be used by nurses as a reference in caring for GI cancer patients.

RESUMEN

PURPOSE: The aims of this study were to identify the factors and reasons impacting discordance with the treatment plan in head and neck cancer (HNC) patients and compare the differences between the concordance group and the discordance group. METHODS: This secondary analysis was conducted from population-based data from Taiwan collected from January 1, 2016, to June 30, 2018. Logistic regression analysis was used to identify the factors related to discordance with the treatment plan. RESULTS: We examined 1095 HNC patients, 12.1% of whom were discordant with treatment. Patients with advanced cancer stage, old age, and treatment plans of best supportive care (BSC) or surgery combined with radiation (RT), chemotherapy (CT), or chemoradiation (CCRT) were more likely to have discordance with their treatment plan. Of the 133 patients who were discordant with their treatment plan, the top reasons were as follows: "patients or their family considered patients' poor physical condition (chronic disease or unstable systemic disease), difficulty in enduring any condition likely to cause physical discomfort from disease treatment," "inconvenient transportation," and "disease progression." CONCLUSIONS: Patients' cancer stage, age, and types of treatment plans recommended significantly influenced discordance with treatment plan. Poor physical condition was the major reason for discordance with the treatment plan. Patients in the concordance group were significantly more likely than those in the discordance group to be younger than 65 years, have less advanced cancer stage, and be recommended to receive surgery rather than any other regimen. Multidisciplinary team care can help patients make positive decisions about treatment.

RESUMEN

PURPOSE: To identify factors associated with resilience in primary caregivers of patients with advanced oral cavity cancer within the first 6 months post-treatment. DESIGN: A cross-sectional study. METHODS: We recruited patient-primary caregiver dyads from the outpatient radiation department of a medical center in Northern Taiwan. Patients were assessed using a set of structured questionnaires to measure performance status and demographic and clinical characteristics. Primary caregivers were measured in their social support, resilience, and care characteristics. RESULTS: Of the 148 dyads surveyed, 33.8% of primary caregivers reported moderately low to moderate resilience, and 61.5% reported low resilience. Greater resilience of primary caregivers was associated with the primary caregiver factors of younger age, lower educational level, and more affectionate social support; and greater resilience was associated with the patient factors of better performance status and older age. These factors explained 40.4% of the variance in resilience. CONCLUSIONS: Patients' performance status and primary caregivers' affectionate social support strongly influence overall resilience and each domain of resilience. CLINICAL RELEVANCE: Providing primary caregivers with sufficient social resources and a support group can help them cope with the demands of caregiving for loved ones with oral cavity cancer.

RESUMEN

OBJECTIVE: The purpose of this study of posttreatment oral cavity cancer (OCC) patients was to identify factors associated with self-reported overall body image, perceived attractiveness, and dissatisfaction with body appearance. METHODS: This cross-sectional study recruited patients with OCC from the outpatient radiation department of a single cancer center in Northern Taiwan. Demographic and clinical characteristics were recorded, and patients were assessed using the Hospital Anxiety and Depression Scale (HADS), the Liebowitz Social Anxiety Scale (LSAS), the University of Washington Quality of Life Scale (UW-QOL), and the Body Image Scale (BIS). RESULTS: A total of 168 patients were included in this current study, 76 females and 92 males. Negative overall body image was associated with greater degree of depression, greater fear of social interactions, poorer social-emotional function, receipt of surgery, female gender, and greater avoidance of social interaction; these factors explained 49.0% of the variance in this outcome measure. Poor perceived attractiveness was associated with greater depression, greater fear of social interaction, and receipt of surgery; these factors explained 25.4% of the variance in this outcome measure. Dissatisfaction with body appearance was associated with poor social-emotional function, greater fear of social interaction, receipt of reconstruction, advanced cancer stage, and female gender; these factors explained 52.2% of the variance in this outcome measure. CONCLUSIONS: This study of posttreatment OCC patients indicated that depression and fear of social interaction strongly influenced overall body image, perceived attractiveness, and dissatisfaction with body appearance.

RESUMEN

OBJECTIVE: The purpose of this study of survivors of head and neck cancer was to evaluate the effects of a behavior change program and health education on depression, fear of social interactions, avoidance of social interactions, physical function, and social-emotional function. METHODS: This was a randomized controlled trial of 100 subjects, in which changes in the scores of several psychometric scales were recorded for an experimental group (behavior change program and health education) and a control group (routine care only). Assessments were performed at baseline (T0), and at 1 month (T1), 2 months (T2), and 3 months (T3) after completing the intervention. RESULTS: After the intervention, the experimental group reported significantly less fear of social interactions, less avoidance of social interactions, and better physical function than the control group. The experimental group also had less depression at T3 than at T0, although there was no such change in the control group. Analysis of physical function indicated that both groups experienced improvements from T0 to T1, slight declines from T1 to T2, and slight declines from T2 to T3; however, both groups had significantly better physical function at T3 than at T0. CONCLUSIONS: Head and neck cancer patients who received a behavior change program and health education reported less fear of social interactions, less avoidance of social interactions, and improved physical function during the 3 months after this intervention.

RESUMEN

OBJECTIVE: To compare the levels of social support, physical function, and social-emotional function between oral cavity cancer survivors who did or did not resume work 6 months or longer after treatment completion. METHODS: This cross-sectional study examined survivors of oral cavity cancer who were treated at the outpatient radiation department of a medical center in Northern Taiwan. Questionnaires were used to collect data regarding perceived social support, physical function, social-emotional function, and return to work status after treatment. Logistic regression was conducted to determine factors related to returning to work. RESULTS: We examined 174 survivors of oral cavity cancer, 55.2% of whom returned to work after treatment. Relative to survivors who returned to work, those who did not return to work reported needing greater tangible social support, having fewer positive social interactions, having poorer physical function, and having poorer social-emotional function. Multivariable analysis indicated that younger age (OR = 0.864, P < .05), higher family income (OR = 10.835, P < .05), sufficient tangible social support (OR = 0.943, P < .05), positive social interaction (OR = 1.025, P < .05), and better physical function (OR = 1.062, P < .05) were significantly associated with the return to work. CONCLUSIONS: Survivors of oral cavity cancer who did not return to work had worse physical and social-emotional function and required more tangible social support and positive social interactions. Providing occupational rehabilitation and counseling for oral cavity cancer survivors may help them return to work.

RESUMEN

Fern spores were traditionally classified into chlorophyllous (green) and nonchlorophyllous (nongreen) types based on the color visible to the naked eye. Recently, a third type, "cryptochlorophyllous spores", is recognized, and these spores are nongreen under white light but contain chlorophylls. Epifluorescence microscopy was previously used to detect chlorophylls in cryptochlorophyllous spores. In addition to epifluorescence microscopy, current study performed some other approaches, including spore-squash epifluorescence, absorption spectra, laser-induced fluorescence emission spectra, thin layer chromatography (TLC), and ultra-high performance liquid chromatography with ultraviolet and mass spectrometric detection (UHPLC-UV-MS) in order to detect chlorophylls of spores of seven ferns (Sphaeropteris lepifera, Ceratopteris thalictroides, Leptochilus wrightii, Leptochilus pothifolius, Lepidomicrosorum buergerianum, Osmunda banksiifolia, and Platycerium grande). Destructive methods, such as TLC and UHPLC-UV-MS, successfully detected chlorophylls inside the spores when their signals of red fluorescence under epifluorescence microscope were masked by spore wall. Although UHPLC-UV-MS analysis was the most sensitive and reliable for determining the chlorophylls of spores, spore-squash epifluorescence is not only reliable but also cost- and time-effective one among our study methods. In addition, we first confirmed that Lepidomicrosorium buergerianum, Leptochilus pothifolius, Leptochilus wrightii, and Platycerium grande, produce cryptochlorophyllous spores.

RESUMEN

A wide variety of sulfur metabolites play important roles in plant functions. We have developed a precise and sensitive method for the simultaneous measurement of several sulfur metabolites based on liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) and (34)S metabolic labeling of sulfur-containing metabolites in Arabidopsis thaliana seedlings. However, some sulfur metabolites were unstable during the extraction procedure. Our proposed method does not allow for the detection of the important sulfur metabolite homocysteine because of its instability during sample extraction. Stable isotope-labeled sulfur metabolites of A. thaliana shoot were extracted and utilized as internal standards for quantification of sulfur metabolites with LC-MS/MS using S-adenosylmethionine (SAM), S-adenosylhomocysteine (SAH), methionine (Met), glutathione (GSH), and glutathione disulfide (GSSG) as example metabolites. These metabolites were detected using electrospray ionization in positive mode. Standard curves were linear (r(2)>0.99) over a range of concentrations (SAM 0.01-2.0µM, SAH 0.002-0.10µM, Met 0.05-4.0µM, GSH 0.17-20.0µM, GSSG 0.07-20.0µM), with limits of detection for SAM, SAH, Met, GSH, and GSSG of 0.83, 0.67, 10, 0.56, and 1.1nM, respectively; and the within-run and between-run coefficients of variation based on quality control samples were less than 8%.

RESUMEN

Objective: The aim of the study was to evaluate the effects of a return to work (RTW) program on perceived health status, barriers to returning to work, fear of cancer progression, social support, physical function, and psychosocial function in head and neck cancer (HNC) patients. Methods: A randomized controlled trial with repeated measures was conducted. The 70 HNC patients were randomly assigned into two groups: 35 in the experimental group (RTW) and 35 in the control group (usual care). Patients were assessed at four time points: baseline (T0) (6 months after completing treatment), and then at 9-, 12-, and 15-months (T1, T2, and T3, respectively) after completing treatment. Patients completed a self-reported questionnaire, including measures of perceived health status, barriers to returning to work, fear of cancer progression, social support, physical function, and psychosocial function. Results: Patients in the experimental group had significantly greater perceived health status and better psychosocial function compared to those in the control group. Compared to T0, at T4, participants in both groups had significantly lower levels of barriers to returning to work, fear of cancer progression, social support, and higher levels of physical function. Conclusions: The RTW program effectively improved perceived health status and psychosocial function in HNC patients. Survivorship care should include a transitional return-to-work program to help patients transition back to work. Trial registration: NCT04322695.

RESUMEN

Head and neck cancer (HNC) patients who are unable to return to work after completing treatment might face financial loss and reduced self-esteem. The aim of this study was to identify factors influencing a return to work in HNC cancer patients in the first 6 months after treatment. This cross-sectional study examined HNC patients who completed treatment from the outpatient radiation department of a single cancer center in northern Taiwan. Patients were assessed according to psychological distress, patient-perceived health status, barriers to returning to work, and facilitators of returning to work. Of the 106 HNC patients surveyed, 54.7% successfully returned to work. Barriers to returning to work included poor self-perception of health, greater psychological distress, and age ≥50 years. Patients who had higher psychological distress, returned to work after start of the pandemic, or received reconstruction surgery were less likely to experience a positive environment facilitating a return to work.

RESUMEN

OBJECTIVES: The present study aimed to evaluate the effects of a nurse-led survivorship care program (SCP) on emotional distress, social support, physical health, mental health, and resilience in primary caregivers of patients with advanced head and neck cancer. DATA SOURCES: A randomized controlled trial was conducted. One hundred patient-primary caregiver dyads were randomized into the nurse-led SCP group (experimental) or the usual care group (control). Participants completed a self-reported questionnaire, including measures of emotional distress, social support, physical health, mental health, and resilience. After 6 months, the experimental group reported a significant improvement in emotional distress, social support, physical health, mental health, and resilience. Compared with the control group, measures of emotional distress, physical health, overall resilience, and the resilience aspects of equanimity and perseverance improved in the experimental group. CONCLUSION: An SCP may feasibly help alleviate emotional distress, improve social support, increase physical and mental health, and strengthen resilience in the primary caregivers of patients with head and neck cancer. Health care providers should encourage primary caregivers to join an SCP. IMPLICATIONS FOR NURSING PRACTICE: The nurse-led SCP can be applied before patients complete treatment, which may increase the positive effect on physical health and adaptation.
