RESUMO
PURPOSE: In the health-care system within hospitals, Taiwanese patients usually play the role of passively cooperating with health-care professionals. Therefore, patients rarely make their own treatment decisions. This study evaluated the level of patient education and patient satisfaction in relation to empowerment level in Taiwan. METHODS: A cross-sectional survey by a self-administered structured questionnaire was carried out with 618 inpatients from the four hospitals. Statistical analyses were then conducted. Analysis of covariance and post-hoc comparison was used to compare differences between the level of patient empowerment, age, and education as covariates in the model. RESULTS: This study found that 21.2% and 35.6% of participants were highly empowered and well empowered, respectively. Years of education is a significant covariate in the counselling domain of patient education. Even after controlling for age and education level, the counselling, answer question and justifying action, providing information scores remain significant for all levels after adjusting for the effects of degree of patient empowerment. Patients with higher empowerment also having more-sufficient patient education, indicating a tendency toward higher patient satisfaction. Patient education and counselling practices in Taiwan's clinical practice could be improved to enhance patient empowerment and ensure health-care systems are person-centred. CONCLUSIONS: To move more toward highly patient empowerment, we suggest that health-care professionals advocate a patient-empowerment approach and to provide more counselling related to patients' illnesses and possible treatments.
RESUMO
We report a new peptide-based urchin-shaped structure prepared through two-step self-assembly of tetraphenylethylene-diserine (TPE-SS). Hydrogelation generated nanobelts through the first stage of self-assembly of TPE-SS; these nanobelts further transformed on silicon wafers into urchin-like microstructures featuring nanosized spines. The presence of the TPE moiety in the hydrogelator resulted in aggregation-induced emission characteristics both in the solution and in the gel phases. TPE-SS has the lowest molecular weight of any TPE-capped hydrogelator with ß-sheet-like structures under physiological pH. This new design strategy appears to be useful for generating three-dimensional self-assembled microstructures and multifunctional biomaterials. We found that TPE-SS is biocompatible with human mesenchymal stem cells and breast cancer cells, making them potential applications in tissue engineering and biomedical research.

BACKGROUND: Recently, a data-driven regression analysis method was developed to utilize the resting-state (rs) blood oxygenation level-dependent signal for cerebrovascular reactivity (CVR) mapping (rs-CVR), which was previously optimized by comparing with the CO2 inhalation-based method in health subjects and patients with neurovascular diseases. PURPOSE: To investigate the agreement of rs-CVR and the CVR mapping with breath-hold MRI (bh-CVR) in patients with gliomas. STUDY TYPE: Retrospective. POPULATION: Twenty-five patients (12 males, 13 females; mean age ± SD, 48 ± 13 years) with gliomas. FIELD STRENGTH/SEQUENCE: Dynamic T2*-weighted gradient-echo echo-planar imaging during a breath-hold paradigm and during the rs on a 3-T scanner. ASSESSMENT: rs-CVR with various frequency ranges and resting-state fluctuation amplitude (RSFA) were assessed. The agreement between each rs-based CVR measurement and bh-CVR was determined by voxel-wise correlation and Dice coefficient in the whole brain, gray matter, and the lesion region of interest (ROI). STATISTICAL TESTS: Voxel-wise Pearson correlation, Dice coefficient, Fisher Z-transformation, repeated-measure analysis of variance and post hoc test with Bonferroni correction, and nonparametric repeated-measure Friedman test and post hoc test with Bonferroni correction were used. Significance was set at P < 0.05. RESULTS: Compared with bh-CVR, the highest correlations were found at the frequency bands of 0.04-0.08 Hz and 0.02-0.04 Hz for rs-CVR in both whole brain and the lesion ROI. RSFA had significantly lower correlations than did rs-CVR of 0.02-0.04 Hz and a wider frequency range (0-0.1164 Hz). Significantly higher correlations and Dice coefficient were found in normal tissues than in the lesion ROI for all three methods. DATA CONCLUSION: The optimal frequency ranges for rs-CVR are determined by comparing with bh-CVR in patients with gliomas. The rs-CVR method outperformed the RSFA. Significantly higher correlation and Dice coefficient between rs- and bh-CVR were found in normal tissue than in the lesion. LEVEL OF EVIDENCE: 3 TECHNICAL EFFICACY STAGE: 2.

Malnutrition is associated with treatment-related toxicities (TRT) in adults with solid tumors and in children with leukemia. Few studies have assessed whether malnutrition in pediatric patients treated for solid tumors impacts risk for TRT, relapse, and/or survival. To address this knowledge gap, this retrospective study evaluated the association between body mass index (BMI) at diagnosis, and imputed BMI during therapy, on the prevalence of TRT, specific toxicities, relapse, and survival in pediatric patients with solid tumors treated with cisplatin-containing regimens. Kaplan-Meier curves and regression models evaluated the association between patient-specific characteristics (including BMI) and TRT, relapse, and survival. The cohort included 221 patients, of whom 22% were malnourished at diagnosis (10% were underweight and 12% were obese). Most patients (60%) experienced at least one severe TRT, and 30% developed more than one severe TRT. Most patients with obesity at diagnosis remained obese during therapy (62%). In multivariable analysis, obesity at diagnosis was significantly associated with a more than threefold greater risk for developing severe TRT (p = 0.037), specifically for acute or chronic kidney injury (p = 0.014). Obesity at diagnosis and adolescent and young adult age (≥15 years at diagnosis) were associated with worse event-free survival (hazard ratio [HR] 2.32, p = 0.024 and HR 2.28, p = 0.010, respectively) and overall survival (HR 3.69, p = 0.006 and HR 2.6, p = 0.012, respectively). Obese and older patients therefore constitute populations at risk for poorer outcomes. Prospective studies are warranted to gain further insight into the mechanism and role of obesity and adolescence in developing TRT and/or treatment failure.

OBJECTIVE: To identify risk factors for glycemic failure in youth with type 2 diabetes (T2D). METHODS: A retrospective review of HbA1c, anthropomorphic measures, medication records, and laboratory studies was performed using registry data from a dedicated pediatric T2D clinic. Latent profile analysis (LPA) was performed to model longitudinal trajectory of HbA1c over 5 years. RESULTS: The registry includes 229 youth with T2D, of whom 80% self-identify as Latinx. The odds ratio (OR) for uncontrolled diabetes 5 years after diagnosis correlated with diagnostic HbA1c, with OR of 2.41 if HbA1c at diagnosis >8.5% (sensitivity 68%, specificity 54%, P = .015). LPA modeling identified three HbA1c profiles: (a) mean HbA1c <8% throughout the 5 years, (b) persistent elevation of mean HbA1c >9%, and (c) mean HbA1c of 12% at diagnosis, rapid decline to 6.4% by 4 to 6 months, and increase to 11% by 18 months. Our analysis of medication regimen showed that, amongst patients treated with metformin, the addition of multiple daily injections (MDI) did not improve HbA1c compared to those on basal insulin. Finally, weight loss over the 1 year after diagnosis correlated with improvement in HbA1c in both subjects prescribed metformin monotherapy, as well as insulin-containing regimen. CONCLUSION: Youth with T2D exhibit distinct HbA1c profiles. Patients with diagnostic HbA1c >8.5% are at high risk for glycemic failure, irrespective of short-term improvement in HbA1c. Weight management has the potential to improve short-term HbA1c outcome in youth with T2D. Additional studies are needed to determine the role of medication adherence on glycemic control.

BACKGROUND: Trigeminal neuralgia (TN) is characterized by facial pain that may be sudden, intense, and recurrent. Neurosurgical interventions, such as radiofrequency rhizotomy, can relieve TN pain, but their mechanisms and effects are unknown. The aim of the present study was to investigate the microstructural tissue changes of the trigeminal nerve (TGN) in patients with TN after they underwent radiofrequency rhizotomy. METHODS: Thirty-seven patients with TN were recruited, and diffusion tensor imaging was obtained before and two weeks after radiofrequency rhizotomy. By manually selecting the cisternal segment of the TGN, we measured the volume of the TGN, fractional anisotropy (FA), apparent diffusion coefficient (ADC), axial diffusivity (AD), and radial diffusivity (RD). The TGN volume and mean value of the DTI metrics of the post-rhizotomy lesion side were compared with those of the normal side and those of the pre-rhizotomy lesion side, and they were correlated to the post-rhizotomy visual analogue scale (VAS) pain scores after a one-year follow-up. RESULTS: The alterations before and after rhizotomy showed a significantly increased TGN volume and FA, and a decreased ADC, AD, and RD. The post-rhizotomy lesion side showed a significantly decreased TGN volume, FA, and AD compared with the normal side; however, no significant difference in the ADC and RD were found between the groups. The TGN volume was significantly higher in the non-responders than in the responders (P = 0.016). CONCLUSION: Our results may reflect that the effects of radiofrequency rhizotomy in TN patients include axonal damage with perineural edema and that prolonged swelling associated with recurrence might be predicted by MRI images. Further studies are necessary to understand how DTI metrics can quantitatively represent the pathophysiology of TN and to examine the application of DTI in the treatment of TN.

PURPOSE: Patient empowerment is a paradigm of clinical practice. The goal of patient empowerment is to lead patients' health and wellbeing. The aim of this study is to evaluate the relation between patient education, patient empowerment and patient satisfaction based on multi-hospital cross-sectional study design in Taiwan. METHODS: In this cross-sectional survey, 609 inpatients in four teaching hospitals in northern Taiwan from August 2009 to July 2010 were recruited. Data were collected using Chinese version of the Patient Perceptions of Empowerment Scale (PPES), Sufficiency of Patient Education Questionnaire (SPEQ) and Patient Satisfaction Questionnaire (PSQ). The multiple linear regression model was used to assess the independent effects of relevant factors on patient empowerment after controlling for the covariates. RESULTS: The overall mean empowerment scores was 44.80±5.94. There was a significant difference between the total scores and four dimensions of patient empowerment at different hospitals (t=5.44, p≤0.01). Sufficient patient education (ß=0.568, 95%CI: 0.486-0.649) and patient satisfaction (ß=0.317, 95%CI: 0.259-0.375) could significantly predict patient empowerment based on the multiple linear regression analysis, with a total variance was 54.4%. CONCLUSIONS: In conclusion, both sufficient patient education and patient satisfaction were positively related to patient empowerment. Hospitals in Taiwan should try to improve their patients' active involvement toward empowerment.

Attending lectures and reading are two common approaches to acquiring knowledge, while repetitive practice is a common approach to acquiring skills. Nurturing proper attitudes in students is one of the greatest challenges for educators. Health professionals must incorporate empathy into their practice. Creative teaching strategies may offer a feasible approach to enhancing empathy-related competence. The present article focuses on analyzing current, empathy-related curriculums in nursing education in Taiwan, exploring the concepts of empathy and game-based learning, presenting the development of an empathy board game as a teaching aid, and, finally, evaluating the developed education application. Based on the learner-centered principle, this aid was designed with peer learning, allowing learners to influence the learning process, to simulate the various roles of clients, and to develop diverse interpersonal dialogues. The continuous learning loops were formed using the gamification mechanism and transformation, enabling students to connect and practice the three elements of empathy ability: emotion, cognition and expression. Via the game elements of competition, interaction, storytelling, real-time responses, concretizing feedback, integrated peer learning, and equality between teachers and students, students who play patient roles are able to perceive different levels of comfort, which encourages the development of insight into the meaning of empathy. Thereby, the goals of the empathy lesson is achievable within a creative game-based learning environment.

AIMS AND OBJECTIVES: To evaluate the effectiveness of a psychoeducational programme in enhancing motivation to change alcohol-addictive behaviour. BACKGROUND: The prevalence of alcohol abuse has increased over the past 10 years, and the age of initial alcohol use has decreased gradually in Taiwan. Alcohol dependence is one of the leading causes of disability and has led to increases in the incidence of crime and violence, with alcohol abuse identified as a problem in society. DESIGN: A quasi-experimental design with nonequivalent pre/post-testing was used. METHODS: Alcohol-dependent inpatients undergoing alcohol treatment were selected from the psychiatric ward of a teaching hospital in northern Taiwan. The effectiveness of the psychoeducational programme in enhancing motivation to change alcohol-addictive behaviour was evaluated with the Severity of Alcohol Dependence Data Questionnaire and the Stages of Change Readiness and Treatment Eagerness Scale. In total, 24 and 51 participants were recruited to the experimental and control groups, respectively, for the baseline survey, and 14 and 17 were in the final survey, respectively. RESULTS: After adjustment for baseline survey scores, the experimental group showed significantly greater increases in recognition and ambivalence relative to those observed in the control group. CONCLUSIONS: The results not only showed that the psychoeducational programme was effective in reinforcing addicted inpatients' motivation for changing their drinking behaviour but also provided clinical nurses with practical methods via which to enhance patient motivation. RELEVANCE TO CLINICAL PRACTICE: The psychoeducational programme could assist clinical nurses in helping alcohol-dependent patients to recognise the nature of their problematic drinking; increase participants' ambivalence towards their drinking behaviour, leading to the contemplation of change; and strengthen the possibility that they will change their addictive behaviour.

In this study, we reported a significant difference in the supramolecular hydrogelation of newly discovered NI-GFF (NI-Gly-l-Phe-l-Phe) and NI-FFG (NI-l-Phe-l-Phe-Gly) on the basis of their phase diagrams. With a small difference in the peptide chain between NI-GFF and NI-FFG, we observed a significant difference in their self-assembly properties; NI-GFF formed a stable gel at neutral pH, whereas NI-FFG did not, under the same conditions. From spectroscopic and computational studies, intermolecular π-π interactions and extended hydrogen bonding interactions might reinforce the intermolecular interactions of NI-GFF, which may facilitate the formation of the self-assembled nanostructures and the hydrogel. In addition, the aggregation-induced emission (AIE)-active NI-GFF reveals relatively good biocompatibility compared with that of NI-FFG for two commonly used cell lines, suggesting that it is a promising candidate for use as a supramolecular material in biomedical applications. Our results highlight the importance of tripeptide sequences in a self-assembling hydrogel system.

Herein, we report a tetraphenylethylene-diglycine (TPE-GG) hydrogelator from a systematic study of TPE-capped dipeptides with various amphiphilic properties. From a chemical design, we found that the hydrogelation of TPE-GG molecules can be utilized to generate supramolecular nanostructures with a large TPE-based nanobelt width (â¼300 nm) and lateral dimension ratio (>30 fold). In addition, TPE-GG has the lowest molecular weight and minimum number of atoms compared to any TPE-capped peptide hydrogelator reported to date. This minimal self-assembled hydrogelator can fundamentally achieve the gel features compared with other TPE-capped peptides. A combined experimental and computational study indicates the π-π interactions, electrostatic interactions and hydrogen-bonding interactions are the major driving forces behind the formation of self-assembled nanobelts. This study demonstrates the importance of structure-property relationships and provides new insights into the design of supramolecular nanomaterials.

Taiwanese nurses face increasingly demanding working conditions along with a distinctive culture where family members participate in medical decisionmaking. This research explores Taiwanese nurses' perceptions of patient education, with a focus on the difficulties. Data were collected by in-depth focus group discussions with nursing staff (n=53) from the medical and surgical wards of two teaching hospitals. Transcripts were analyzed and revealed six themes: source of fulfillment and pressure; excessive workload; alternating between patients; not knowing who to teach; difficulty in communication; and disrupted confidence and work rhythm. Research findings could help managers understand the difficulties faced by nurses in providing health education. Nurses should broaden the scope of patient education activities to include family members. Additionally, nurses should discuss patients' desires and expectations from family members in medical treatment and decisionmaking.

In this study, we examined the self-assembly of four dipeptides conjugated with the electroactive dye naphthalenediimide (NDI). The presence of the NDI group at the N-terminus of Phe-Phe and Phe-Gly promoted the formation of one-dimensional (1-D) nanostructures and three-dimensional (3-D) colored hydrogels under both acidic and physiological conditions. The 1-D nanostructures of these gels were stabilized through intermolecular π-π interactions of the conjugated systems and extended hydrogen bonding of the dipeptide units.

Supramolecular assembly of donor-acceptor complexes as the key component in organic functional nanomaterials is a promising approach for future electronic devices. One representative example of the donor-acceptor complexes is the naphthalene diimide-pyrene (NDI-Py) system, which shows fascinating photoelectric properties. Herein, the analysis of the π-π interactions between NDI and Py has been investigated using the DFT/M06-2X and reduced density gradient methods. According to the calculations, the attractive forces for the stabilization of the NDI-Py dimer are dependent on the rotation angles, which provide physical insight into the experimental data reported by Wilson and co-workers (Langmuir, 2011, 27, 6554). Our results not only provide computational evidence for the origin of the rotation in the crystal structure of the NDI-Py but also address the role of the charge-transfer attractions in the complexes.
RESUMO
BACKGROUND: When depressed patients are in remission, the clinical characteristics indicate that they are able to participate in social activities more regularly, and their impairment in daily functioning is improved. The present study examines the clinical characteristics associated with one- and two month clinical response in outpatients with Major Depressive Disorder (MDD) in Taiwan. METHODS: A total of 160 outpatients were initially recruited from the medical centre in Taiwan. Of these participants, 151 MDD patients completed the baseline-assessment interview, 111 were interviewed and assessed again 4 weeks later, and 78 completed the final interview and assessment 8 weeks later. In the present study, asymptomatic was defined as scoring ≤ 7 on the Hamilton Depression Rating Scale (HAM-D); partially symptomatic was defined as scoring 8-14; fully symptomatic was defined as scoring ≥15. Finally, asymptomatic, partially symptomatic, and fully symptomatic were defined in patients with MDD respectively as in full remission, in persistent depressive symptom, and in episode. RESULTS: Of the remaining 78 patients, a total of 21 (26.9%) were in full remission, 35 (44.9%) were in persistent depressive symptom, and 22 (28.2%) were in episode. Patients in full remission were older (p = 0.03), exhibited greater psychosocial functioning, (p < 0.001), held more-positive beliefs regarding antidepressant medication (p = 0.03), had higher self-efficacy (p = 0.001), and scored lower for neuroticism (p = 0.003), as compared to patients in episode. Younger patients were more prevalent in persistent depression. Repeated-measures ANOVA revealed that differences in four factors (psychosocial functioning, beliefs regarding antidepressant medication, self-efficacy in managing and preventing depression, and neuroticism) were significantly different between full remission and episode. Episode was significantly associated with psychosocial-functioning impairment (OR = 1.12, 95% CI: 1.00-1.26) and poorer self-efficacy (OR = 0.91, 95% CI: 0.82-1.00). CONCLUSIONS: Our findings identify significant factors of full remission, persistent depressive symptom, and episode. We highlight the importance of enhancing patients' psychosocial functioning and self-efficacy until achieving full remission. Suggestions are provided for clinical health-care management services in Taiwan.

AIMS AND OBJECTIVES: To explore women's perspectives on deciding to undergo hysterectomy for benign conditions based on physicians' recommendations and the women's own judgement. BACKGROUND: Hysterectomy is the second most common surgical procedure worldwide. Although most hysterectomies are elective, physicians may recommend treatment that involves a loss of sexuality or ovary removal, creating a difficult choice for women. DESIGN: Qualitative, in-depth interview METHODS: A purposive sample of 17 women was recruited. The women had decided to undergo hysterectomy after the diagnosis of uterine fibroids. All these women had already decided not to have more children. Data were collected by in-depth interviewing, and content analysis was used to analyse the data. RESULTS: Our study revealed five themes: release from stress, inescapable fate, positive support, hoping for peace of mind and sense of trust. CONCLUSIONS: The participants felt that mental and physical health were the most important considerations, noting that when women no longer want children, a uterus is useless. The women believed that they retained their womanhood, even without a uterus, and were satisfied with the outcomes of their hysterectomy decisions. RELEVANCE TO CLINICAL PRACTICE: Our findings might serve as educational and counselling reference materials for healthcare providers, ensuring that women receive appropriate care quality and have their needs met. Healthcare providers can then maximise women's empowerment, deepen their awareness of body image and their concept of self-care and help them to clearly perceive their own concerns and needs so that they can make suitable decisions.

Quaternary phosphonium salts, a significant category of organophosphorus compounds, have garnered substantial attention from chemists due to their wide range of applications across various research areas. These compounds are utilized in organic synthesis, catalysis, medicinal chemistry, natural materials, and coordination chemistry. Their versatility and effectiveness in these fields make them valuable tools in scientific research. Despite their extensive use in various applications, the potential of quaternary phosphonium compounds as fluorescent agents for revealing latent fingerprints (LFPs) remains largely unexplored, presenting an exciting opportunity for further research and development in forensic science. In this study, we designed molecules that combine the aggregation-induced emission (AIE) chromophore with triphenylphosphine to create a series of novel AIE amphiphiles, namely TPP1, TPP2, and TPP3. Through precise adjustment of the carbon chain length between the phenoxy group and the terminal triphenylphosphine, we were able to finely tune the nanostructures and hydrophobicity of the materials. TPP3 emerged as the optimal candidate, possessing the ideal particle size and hydrophobicity to effectively bind to LFPs, thus enabling efficient fingerprint visualization with enhanced fluorescence upon aggregation. Our findings introduce an innovative approach to fingerprint visualization, offering high selectivity, superior imaging of level 3 structures, and long-term effectiveness (up to 30 days). Additionally, TPP3's outstanding performance in imaging level 3 structures of LFPs is beneficial for analyzing incomplete LFPs and identifying individuals. By significantly improving the detection and analysis of LFPs, this approach ensures more accurate and reliable identification, making it invaluable for forensic investigations and security measures. The adaptability of these compounds to various fingerprint surfaces highlights their potential in diverse practical applications, enhancing their utility in both forensic science and security fields. This versatility allows for precise fingerprint visualization across different scenarios, making them a critical tool for advancing biometric and security technologies.

Hydrogels, recognized for their flexibility and diverse characteristics, are extensively used in medical fields such as wearable sensors and soft robotics. However, many hydrogel sensors derived from biomaterials lack mechanical strength and fatigue resistance, emphasizing the necessity for enhanced formulations. In this work, we utilized acrylamide and polyacrylamide as the primary polymer network, incorporated chemically modified poly(ethylene glycol) (DF-PEG) as a physical crosslinker, and introduced varying amounts of methacrylated lysine (LysMA) to prepare a series of hydrogels. This formulation was labeled as poly(acrylamide)-DF-PEG-LysMA, abbreviated as pADLx, with x denoting the weight/volume percentage of LysMA. We observed that when the hydrogel contained 2.5% w/v LysMA (pADL2.5), compared to hydrogels without LysMA (pADL0), its stress increased by 642 ± 76%, strain increased by 1790 ± 95%, and toughness increased by 2037 ± 320%. Our speculation regarding the enhanced mechanical performance of the pADL2.5 hydrogel revolves around the synergistic effects arising from the co-polymerization of LysMA with acrylamide and the formation of multiple intermolecular hydrogen bonds within the network structures. Moreover, the acid, amine, and amide groups present in the LysMA molecules have proven to be instrumental contributors to the self-adhesion capability of the hydrogel. The validation of the pADL2.5 hydrogel's exceptional mechanical properties through rigorous tensile tests further underscores its suitability for use in strain sensors. The outstanding stretchability, adhesive strength, and fatigue resistance demonstrated by this hydrogel affirm its potential as a key component in the development of robust and reliable strain sensors that fulfill practical requirements.
RESUMO
AIMS AND OBJECTIVES: To describe factors associated with the subjective quality of life of individuals who had attempted suicide. BACKGROUND: Although quality of life has been a focus of concern in mental health care, data are lacking on what life is like and what factors are related to an individual's quality of life after a suicide attempt. DESIGN: A cross-sectional, descriptive design was used. METHODS: Participants comprised a convenience sample of 103 individuals who had attempted suicide within the previous three months and received follow-up care from one suicide-prevention centre in northern Taiwan. Participants were assessed for depression and quality of life using the Beck Depression Inventory, Taiwan version and the World Health Organisation Quality of Life Instrument-BREF, Taiwan version, respectively. RESULTS: Almost half the participants (n = 49) had severe depression and one-third of them (n = 30) reattempted suicide while receiving follow-up care. Depression and quality-of-life scores were statistically significantly inversely correlated. participants' quality-of-life scores were most associated with their depressive level, reattempting suicide during suicidal follow-up care, high educational level and older age. CONCLUSIONS: The present study indicates that factors associated with quality of life decreased more in individuals with moderate/severe depression than in those with mild depression. In addition, individuals who reattempted suicide during follow-up care were more likely to suffer from poor life quality. RELEVANCE TO CLINICAL PRACTICE: Mental health professionals should include frequent evaluation of depressive status and quality of life in follow-up care for patients who have recently attempted suicide. Particularly, mental health professionals must treat suicidal individuals with a high tendency to reattempt suicide by establishing trust with them and allowing them to narrate their painful experiences during follow-up care.

Dietary patterns are associated with morbidity and mortality of heart failure. Volume overload was the most common cause for re-hospitalization for heart failure patients. However, recommended preventive strategies of restricting excessive dietary sodium and fluid intake were found to be in vain. This study looks at the preventive dietary instructions from a cultural context, and examined the effects of sodium and fluid restriction on twelve elderly Chinese patients hospitalized with heart failure through a qualitative design. Four themes emerged from the data: medicine-food homology, salt and sodium as synonymous, activity intolerance but still wanting social connections, and barriers to asking questions. Results suggested that living with heart failure is a complex and changeable process for both patients and caregivers. Many patients reported low levels of understanding concerning their symptoms and heart function deterioration. The findings found that good communication requires cultural sensitivity, objective listening to the patient's narrative, and helping patients find meaning between their experiences and symptom control.
