RESUMO

Introduction: Ischemic strokes and their recurrence create an immense disease burden globally. Therefore, preventing recurrent strokes by promoting medication adherence is crucial to reduce morbidity and mortality. In addition, understanding the barriers to medication adherence related to the social determinants of health (SDoH) could promote equity among persons with ischemic stroke. Objective: To explore the barriers to medication adherence among patients with ischemic stroke through the SDoH. Methods: This systematic review included studies published between January 2018 and December 2022 identified through PubMed, MEDLINE, Web of Science, and CINAHL Plus Full Text. The descriptions of the studies were systematically summarized and discussed based on the SDoH from the US Healthy People 2030 initiative. Results: Eight studies met the inclusion criteria and were included in this review. The most common barrier to adherence was inappropriate medication beliefs, medication side effects, and patient-physician relationship, which relate to the dimensions of healthcare access and quality. Health literacy and health perception, dependent on education access and quality, frequently influenced adherence. Other social determinants, such as financial strain and social and community context, were found to alter adherence behaviors. No study addressed the neighborhood and built environment domain. We found that cognitive impairment is another factor that impacts adherence outcomes among stroke patients. Conclusion: Multifaceted approaches are needed to address the SDoH to improve medication adherence among patients with ischemic stroke. This review emphasized strategies, including patient education, provider-patient communication, social support, health literacy, technology, and policy advocacy to enhance adherence.

RESUMO

The purpose of this systematic review was to explore factors affecting nurses' job satisfaction in Saudi Arabian hospitals by utilizing the social determinants of a health model. We conducted a systematic review using three databases (PubMed, PsychINFO, and CINAHL) following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. A total of 235 studies were screened. Of these studies, nine met the inclusion criteria. The studies were appraised using the Joanna Briggs Institute checklist tool. The majority of studies reported that salary, years of experience, nationality, and marital status were factors affecting nurses' job satisfaction. Gender and educational level did not impact job satisfaction for male and female nurses. Overall, the review highlighted some knowledge gaps in the assessment of the impact of social determinants of health regarding gender and educational level on nurses' job satisfaction. Further research is needed to address this knowledge gap.

RESUMO

AIMS AND OBJECTIVES: To investigate socioeconomic, behavioural and healthcare delivery factors that are associated with health outcomes of cancer patients during the COVID-19 pandemic, especially among underserved cancer patients. BACKGROUND: Cancer patients are at a higher risk of adverse physical and mental health outcomes during the pandemic than those without cancer. DESIGN: Cross-sectional online survey. We followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guidelines in this study. METHODS: The sample comprised 322 individuals diagnosed with incident cancer between January 2019 and January 2020. Demographically, 64% were female, 49% had a college degree, 12% were African American, and 88% were White (77% of the Whites were from metropolitan and 23% from nonmetropolitan areas). Descriptive analysis and multivariable regression analyses of global health status, depression and irritability were performed. RESULTS: After adjusting for demographic variables and comorbidity, the feelings of loneliness, crowded living space, lower confidence in taking preventive measures and less satisfaction with telehealth visits were significantly associated with poorer global health, depression and irritability. Daily exercise was associated with better global health, and difficulty in getting medicine was associated with depression and irritability. Moreover, African Americans who felt lonely reported more depression and irritability and those who had less confidence in taking preventive measures reported more irritability than Whites. Respondents having low income and feeling lonely reported more depression than others. CONCLUSIONS: In this study, socioeconomic factors (e.g. loneliness or crowded living conditions) were as important to health outcomes during the pandemic as behavioural (e.g. prevention and exercises) and quality-of-care factors (e.g. telehealth, access to medicine). Disparity was more pronounced in the mental health of African Americans and those with low incomes. RELEVANCE TO CLINICAL PRACTICE: Healthcare providers should promote social support and physical activity for improving health and reducing mental health disparities among cancer patients.

RESUMO

BACKGROUND: Irritability is a common experience of depressed Chinese patients but is understudied and poorly measured. OBJECTIVE: We aimed to assess psychometric properties of a new measure of irritability in Chinese cancer patients across the social and political spectrum. METHODS: The Irritability Scale-Initial Version (TISi) was translated into Chinese and tested in two samples of Chinese cancer patients undergoing treatments: 52 patients in Beijing, China, between 2018 and 2019 and 65 patients in Taipei, Taiwan, in 2020. RESULTS: The Chinese version of TISi demonstrated high internal consistency, high reliability based on the split-half method in the two samples, and satisfactory discriminant validity using the Chinese version of the 17-item Hamilton Rating Scale for Depression and the seven-item depression subscale of the Hospital Anxiety and Depression Scale in the Beijing sample. A confirmatory factor analysis produced factor loadings in both samples, which resembled a sample of American cancer patients. Three TISi items were loaded more highly on the physical instead of the original behavioral subscale in the Beijing sample. A possible influence of cultures was explained. CONCLUSION: The Chinese version of TISi has satisfactory psychometric properties for assessing the level of irritability in Chinese cancer patients. Future large-sample studies are needed to further determine TISi's factorial structure, test-retest reliability, sensitivity to change, and predictive validity for depression in Chinese cancer patients.

RESUMO

BACKGROUND: Association between irritability and depression has been frequently reported, but the nature of this association in the adult population is poorly understood. OBJECTIVES: We examined associations among irritability (e.g., a feeling of agitation), inflammatory biomarkers, and depression during chemotherapy. METHODS: Forty-four patients with nonmetastatic breast cancer were assessed at baseline and after 3 months of chemotherapy on The Irritability Scale-Initial Version, severity and new onset of depressive symptoms using the Hamilton Depression Rating Scale, and serum levels of high-sensitivity C-reactive protein and interleukin 6. RESULTS: At baseline, high-sensitivity C-reactive protein significantly correlated with physical and mood subscales of The Irritability Scale-Initial Version, but not with depression. Irritability and high-sensitivity C-reactive protein significantly predicted the severity and new onset of moderate to severe depressive symptoms over time, while irritability and interleukin 6 significantly predicted new onset of moderate to severe depressive symptoms. CONCLUSION: The findings suggest that irritability is an independent risk factor of depression and associated with increasing high-sensitivity C-reactive protein. Irritability needs to be effectively managed in patients with cancer undergoing chemotherapy to prevent them from developing depressive symptoms. These preliminary findings should be investigated in future large-sample studies.

RESUMO

Purpose: We examined underlying psychosocial processes of a behavioral treatment for urinary incontinence (UI) of prostate cancer survivors.Design: Secondary analysis of data collected from a clinical trial.Sample: Two hundred forty-four prostate cancer survivors who participated in a clinical trial of behavioral intervention to UI as intervention or control subjects.Methods: The participants had a 3-month behavioral intervention or usual care and were followed up for an additional 3 months. They were assessed at baseline, 3, and 6 months. Latent growth curve models were performed to examine trajectories of each study variable and relationships among the variables.Findings: Increasing self-efficacy and social support were significantly and independently associated with more reduction of urinary leakage frequency over time.Implications for psychosocial oncology: Providing problem-solving skills and social support, including peer support, are essential for empowering patients to reduce UI.

RESUMO

BACKGROUND: Irritability is common among people who are physically ill, but a physical underpinning of irritability is not assessed by existing measures. A measure that assesses multidimensionality of irritability can help nurses and clinicians provide better care for people with cancer and, thus, reduce a risk for developing depression during cancer treatment. OBJECTIVES: We pilot tested a new measure, The Irritability Scale-Initial Version (TISi), for assessing irritability of cancer patients on three dimensions: physical, affective, and behavioral. METHODS: We conducted thee pilot studies to develop the 35-item TISi on a 5-point Likert scale. TISi was tested in 48 early-stage, nonmetastasized breast cancer patients at baseline (before) and 3 months (during chemotherapy). Of these patients, 62.5% received neoadjuvant and 37.5% received adjuvant chemotherapy, but none received hormonal treatment before or during the study. Measures of other correlates, including depression, anxiety, symptom distress, and social disconnectedness, were also administered, and biomarkers of hsCRP, TNF-α, IL-6, and BDNF were obtained from blood draws at both assessments. RESULTS: TISi has a high internal consistency (Cronbach's α = .97), satisfactory test-retest reliability (retest r = .69, intraclass correlation coefficient = .86), and moderate correlation with other constructs over time (r ≈ .40-.70). Its physical subscale significantly correlated with hsCRP (r = .32, p = .025) at baseline and TNF-α (r = .44, p = .002) at 3 months. A confirmatory factor analysis yields three factor loadings that are in line with conceptualization of the subscales. DISCUSSION: The findings support psychometric properties of TISi and its application for assessing cancer patients' irritability in multiple dimensions. Further investigation using a large study sample is necessary for improving construct and criterion validity and reducing item redundancy. CONCLUSION: TISi can be used to measure the level of irritability in cancer patients.

RESUMO

PURPOSE: This study aimed to assess whether prostate cancer survivors who received a behavioral intervention to urinary incontinence had experienced a significant mood improvement. METHODS: One hundred fifty-three prostate cancer survivors with persistent incontinence were included in this secondary data analysis. They were randomly assigned to usual care or interventions that provided pelvic floor muscle exercises and self-management skills. All subjects had measures of anxiety, depression, and anger at baseline, 3 months (post-intervention), and 6 months (follow-up). Negative binomial regression analysis was performed to examine the group status, daily leakage frequency at 3 months, and their interactions at 3 months as predictors for mood outcomes at 6 months, controlling for demographic and medical variables. RESULTS: The main effect of daily leakage frequency at 3 months significantly predicted anxiety at 6 months (p < .01). The group main effect on any mood outcomes at 6 months was not statistically significant. The interaction between the group and 3-month leakage had a significant effect on anxiety; intervention subjects achieving a significant leakage reduction at 3 months exhibited significantly less anxiety at 6 months than other subjects (p = .04). Age, employment status, and receiving surgery at baseline were significantly associated with less anxiety, depression, and anger at 6 months. CONCLUSIONS: Reduced urinary incontinence significantly predicted less anxiety, especially among the intervention subjects. The findings suggest a significant association between a behavioral therapy of urinary incontinence and anxiety reduction in prostate cancer survivors.

RESUMO

We conducted a systematic review of literature from the years 2000 through 2017 on the prevalence and burden of lower urinary tract symptoms (LUTS) in men aged 50 and older, and medical treatments of and alternative nonmedical approaches to LUTS. EBSCOhost (Medline with Full Text) was searched for observational, experimental, and review studies in peer-reviewed journals in the English language. Our review found that LUTS were highly prevalent in the world and estimated to affect 2.3 billion people in 2018, with 44.7% being men. Men with LUTS suffer from not only burdensome symptoms such as nocturia and urgency but also adverse psychological consequences (e.g., anxiety and depression) and financial burden. Current medical treatments are clinically effective, but their efficacy is compromised by side effects and low compliance rates. Alternative nonmedical treatments for LUTS were also sought worldwide. There is evidence that lifestyle modifications such as pelvic muscle exercises and bladder training, physical activity, dietary modification, and nutritional supplements can alleviate LUTS and improve patient quality of life; however, evidence based on rigorous methodology remains minimal and cannot be generalized across populations. Evidence of effectiveness of weight loss programs to reduce LUTS is inconclusive. We conclude that although behavioral treatment is a promising approach to alleviating LUTS, especially when combined with medical treatments, well-designed randomized controlled and longitudinal clinical trials on behavioral treatments of LUTS are still needed. Minimally invasive procedures and neuromodulation therapy also show positive results of alleviating LUTS but require further research as well.

RESUMO

PURPOSE: The American Cancer Society (ACS) recommends a follow-up care plan for urinary incontinence of prostate cancer survivors that includes pelvic floor muscle exercise (PFME). We examined potential impacts and access barriers of this recommendation with consideration of patients who normally do not seek such care. METHODS: We compared 267 participants of a clinical trial that tested a PFME-based treatment of urinary incontinence and 69 nonparticipants who declined the trial. All subjects were assessed at baseline, 3, and 6 months on leakage frequency, disease-specific quality of life (QOL), and physical well-being. The nonparticipants were interviewed to examine reasons for intervention refusal. RESULTS: The participating and nonparticipating groups did not differ in most baseline demographics and clinical variables except that the nonparticipants had lower baseline prostate-specific antigen (P ≤ 0.01), lower education levels, and higher likelihood of receiving surgery alone (both P ≤ 0.05). Nonparticipants exhibited significantly more frequent daily leakage, poorer urinary function and bother, and severer urinary problems at 3 and 6 months, as well as worse physical well-being at 6 months, relative to baseline, than the participants. The primary reason for refusal was economical, such as lacking transportation and time for participation. CONCLUSIONS: Urinary function and QOL can worsen without appropriate follow-up care. It is important to make a PFME-based follow-up care program available to all incontinent prostate cancer survivors as recommended by ACS guidelines. IMPLICATIONS FOR CANCER SURVIVORS: Seeking PFME-based treatment is crucial for long-term urinary health outcomes even if present leakage is minor or financial challenge is a concern.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of a behavioral intervention for urinary incontinence of prostate cancer patients. Study subjects were either participating in or eligible but declined (i.e., nonparticipating) the active intervention study. METHODS: The intervention-participating subjects were randomized into three groups, including two intervention groups (support and telephone groups) and a usual care reference group. Intervention-nonparticipating subjects were concurrently enrolled. Intervention effectiveness was assessed on the EQ-5D measure. The costs included direct healthcare cost from medical billing data, patient out-of-pocket expense, caregiver expense, patient loss-of-work cost, and intervention cost. We calculated incremental cost-effectiveness ratios (ICERs) from societal, provider, and patient perspectives. RESULTS: Two hundred and sixty-seven intervention-participating and 69 intervention-nonparticipating post-cancer treatment patients were included. The support and telephone groups, but not the usual care group, had significantly higher EQ-5D index scores (0.054, p = 0.033, and 0.057, p = 0.026, respectively) than the intervention-nonparticipating group at month 6. Within 6 months, intervention cost per subject was $252 and $484, respectively, for providers, and $564 and $203, respectively, for the support and phone group subjects. The final ICERs were $16,759 per quality-adjusted life year (QALY) and $12,561/QALY for support and telephone groups, compared with those of the intervention-nonparticipating group. These ICERs are much smaller than $50,000/QALY, the consensus threshold to determine cost-effectiveness for society. CONCLUSIONS: The study interventions are cost-effective in consideration of eligible patients who declined the interventions. The interventions can provide meaningful outcome improvement on urinary continence at a low cost. This evidence provides critical information for future health policy decision-making of healthcare providers and payers.

RESUMO

This study examined the differences among 57 depressed and nondepressed African-American cancer patients and their use of social support and self-coping resources. In-depth interviews were used to elicit narrative responses and Fisher's exact test was used to compare the 2 groups. The depressed patients, as determined by 3 depression scales, more frequently reported having no supportive family, lacking a support system, having sedentary hobbies, or using alcohol or drugs as coping strategies compared to the nondepressed patients. To better detect and treat depression, health-care providers must carefully evaluate the social support and coping resource needs in this vulnerable population.

RESUMO

PURPOSE: We examined whether an intervention combining pelvic floor muscle exercise and symptom self-management would improve urinary continence and quality of life in patients with prostate cancer. MATERIALS AND METHODS: In a randomized, controlled, longitudinal clinical trial 279 patients with prostate cancer with persistent urinary incontinence were randomized to 1 of 3 groups, including biofeedback pelvic floor muscle exercise plus a support group, the biofeedback exercise plus telephone contact and usual care without intervention. The biofeedback plus support and plus telephone groups received 1 session of biofeedback assisted exercise and 6 biweekly sessions of problem solving therapy. This delivered symptom management skills through a peer support group or telephone contacts for 3 months. All subjects were assessed in blinded fashion at baseline, and 3 and 6 months for urinary leakage frequency, leakage amount and disease specific quality of life. RESULTS: A total of 244 subjects completed the study. The biofeedback plus support and biofeedback plus telephone groups had a lower frequency of daily urinary leakage than the group with usual care without intervention at 3 months (p=0.019 and p≤0.001, respectively) but not at 6 months. The biofeedback plus support group but not the biofeedback plus telephone group had 13.3 gm lower leakage at 6 months than the usual care group (p=0.003). Overall the biofeedback plus support and plus telephone groups reported less symptom severity (p≤0.001) and fewer incontinence problems (p≤0.01) than the usual care group at 6 months. CONCLUSIONS: Study findings show that pelvic floor muscle exercise practice plus symptom self-management in a peer support setting can significantly improve urinary continence and quality of life in patients with prostate cancer.

RESUMO

BACKGROUND: Accurately assessing depression in African American cancer patients is difficult because of the similarities of physical symptoms observed in cancer and depression. AIM: To identify universal and distinctive depressive symptoms in African American cancer patients. METHODS: Seventy-four cancer patients (34 depressed and 23 non-depressed African Americans, and 17 depressed Whites) were interviewed. Qualitative and quantitative analyses were conducted. RESULTS: Compared to non-depressed African Americans, depressed African Americans reported irritability, social isolation, insomnia, fatigue and crying (p ≤ 0.05) more frequently over time. Compared to depressed Whites, they reported sadness, frustration and intrusive thoughts less frequently (p ≤ 0.05), but insomnia and fatigue more frequently (p ≤ 0.05) during cancer treatment. There was little racial difference at the time of interview. CONCLUSION: Depressed African American cancer patients may benefit from more culturally sensitive depression measures that consider symptoms of irritability, social isolation and altered expressions of depressive mood.

RESUMO

This study examined African-American cancer patients' attitudes toward cancer and their relationship with long-term mental health outcomes. Using mixed methods, 74 breast and prostate cancer patients including 34 depressed and 23 nondepressed African-Americans and 17 depressed Whites were interviewed. The interviews were audiotaped and transcribed. Qualitative data analysis identified themes that were coded. The codes were entered into SPSS software. Fisher's exact test was performed to examine group differences in the identified themes. Nondepressed African-Americans more frequently reported cancer as an adaptive experience (p = 0.047) and less frequently as a struggle (p = 0.012) than the depressed African-Americans and Whites. Groups did not significantly differ in the belief that cancer has no cure (p = 0.763), but depressed African-Americans more frequently reported unwillingness to share a cancer diagnosis with family or friends than depressed Whites (p = 0.50). African-Americans' adaptive attitudes to cancer exhibit a pragmatist approach and a worldview shaped by their lived experience. Participants' narratives were examined to illuminate the meanings of these findings. Adaptive attitudes to cancer are associated with better long-term mental health outcomes, and conversely, unpreparedness and inability to cope are associated with a higher risk of depression among African-American cancer patients. Education about cancer and supports for treatment navigation are important measures for improving the long-term mental health of African-Americans living with cancer.

RESUMO

Potential functions: By following the unfolding and refolding of individual human RNA telomeric (TERRA) G-quadruplexes (GQs) in laser tweezers, the mechanical stability and transition kinetics of RNA GQs are obtained. Comparison between TERRA and DNA GQs suggests their different regulatory capacities for processes associated with human telomeres.

RESUMO

OBJECTIVE: This study examined the level of agreement among the Center for Epidemiologic Studies-Depression Scale (CES-D), Hamilton Rating Scale for Depression (HAM-D), Beck Depression Inventory (BDI-II), and Observers' Rating on assessing depression of African American adults with cancer. METHODS: 75 breast and prostate cancer patients (57 African Americans and 18Whites) were interviewed and administered the depression measures. Nonparametric tests were performed to examine the level of measurement agreement by group and the symptom items of CES-D, HAM-D and BDI-II to which African American patients responded differently across measures. RESULTS: The four measures showed agreement on approximately 75% of the cases in both racial groups. However, the difference between measures in identifying depressive cases is marked. The item analysis indicated that most measurement disagreements about African American patients occurred on two items: self-report of depression and sleeping disturbance. CONCLUSION: Measurement discord may be explained by African American's reporting behavior that varies from a self-reported measure to an interviewer-administrated measure of depression. African American patients showed a reluctance to use the word "depression" and a tendency to report sleep disturbance. The findings suggest that accurately assessing depression in these patients requires a consideration of their culturally shaped life experiences.

RESUMO

OBJECTIVE: This study examined spiritual coping (beliefs and practices) of depressed African American cancer patients through a comparison with depressed White cancer patients and non-depressed African American cancer patients. METHODS: Using mixed methods, 74 breast (n=41) and prostate (n=33) cancer survivors including 34 depressed and 23 nondepressed African Americans and 17 depressed Whites were interviewed. The interviews were audiotaped and transcribed. Qualitative data analysis identified themes that were coded. The codes were entered into SPSS software. The Fisher's exact test was performed to examine group differences in self-reported spiritual coping. RESULTS: Significantly more depressed African Americans questioned God when learning of a cancer diagnosis than the non-depressed African Americans (p=.03), but they did not differ from the depressed Whites in this regard (p=.70). Significantly more depressed African Americans reported having faith in God (p=.04), reading the bible (p=.02), and conversing with God (p=.01) than did the depressed Whites. They also reported praying alone (p=.01) more frequently than the depressed Whites who, on the other hand, reported praying with others (non-family members) together for one's own health more frequently (p=.04). CONCLUSIONS: Depression is associated with a deepening need for spirituality and it affects religious beliefs and practices more in African American than White cancer patients. Given its important role in the lives of African American cancer patients, spirituality may be utilized as a reasonable, culturally-based approach to better assess and treat depression in these patients.

RESUMO

The folding kinetics of G-quadruplex forming sequences is critical to their capacity to influence biological function. While G-quadruplex structure and stability have been relatively well studied, little is known about the kinetics of their folding. We employed a stopped-flow mixing technique to systematically investigate the potassium-dependent folding kinetics of telomeric RNA and DNA G-quadruplexes and RNA G-quadruplexes containing only two G-quartets formed from sequences r[(GGA)(3)GG] and r[(GGUUA)(3)GG]. Our findings suggest a folding mechanism that involves two kinetic steps with initial binding of a single K(+), irrespective of the number of G-quartets involved or whether the G-quadruplex is formed from RNA or DNA. The folding rates for telomeric RNA and DNA G-quadruplexes are comparable at near physiological [K(+)] (90 mM) (τ = ~60 ms). The folding of a 2-quartet RNA G-quadruplex with single nucleotide A loops is considerably slower (τ = ~700 ms), and we found that the time required to fold a UUA looped variant (τ > 100 s, 500 mM K(+)) exceeds the lifetimes of some regulatory RNAs. We discuss the implications of these findings with respect to the fundamental properties of G-quadruplexes and their potential functions in biology.

RESUMO

OBJECTIVE: This study examined general and cancer-related stressors of depression that are unique to African-American cancer patients. METHOD: The study used cohort design and mixed methods. Seventy-four breast and prostate cancer survivors including 34 depressed and 23 non-depressed African-Americans and 17 depressed whites were interviewed. Qualitative data analysis identified themes. The thematic codes were converted to a SPSS data set numerically. The Fisher's exact test was performed to examine group differences in the experience of stress. RESULTS: Significantly more depressed African-Americans experienced a dramatic reaction to a cancer diagnosis (p = 0.03) or had concerns about functional decline (p = 0.01), arguments with relatives or friends (p = 0.02), and unemployment status (p = 0.03) than did non-depressed African-Americans, who reacted to the cancer diagnosis as a matter of reality (p = 0.02). Significantly more depressed African-Americans talked about feeling shocked by a cancer diagnosis (p = 0.04) and being unable to do things that they used to do (p = 0.02) than did depressed whites. Qualitative analysis shed light on the extent of such group differences. SIGNIFICANCE OF RESULTS: Distress from the initial cancer diagnosis and functional decline were likely to have triggered or worsened depression in African-American cancer patients. This study highlighted racial differences in this aspect. It is critical to screen African-American cancer patients for depression at two critical junctures: immediately after the disclosure of a cancer diagnosis and at the onset of functional decline. This will enhance the chance of prompt diagnosis and treatment of depression in this underserved population.
