RESUMO

To supply proper and sufficient information and coaching through cancer education, it is important to decide who are risk groups among a target population. A decision tree analysis could help decide the characteristics of the risk groups. This study aimed to identify the combined characteristics of Asian American breast cancer survivors that were closely linked to high needs for help during their breast cancer survivorship process. The data on the needs for help among 185 Asian American breast cancer survivors from a parent clinical trial were included in this analysis. The instruments included the Supportive Care Needs Survey-Short Form 34 (SCNS-SF34) and multiple scales to measure the factors influencing the women's needs for help. The data were analyzed using latent profile analyses and decision tree analyses. The characteristics of the group with the highest needs for help were different depending on the types of needs. For instance, the group with the highest patient care/support needs for help score had high global symptom distress scores (cut point = 2.25) and high physical symptom distress (cut point = 1.57) and did not have regular access to health care (mean = 95.00; node 10). The findings suggest several risk groups to target in future interventions for cancer education to reduce the needs for help among this specific population. Multiple factors that could influence the needs for help among Asian American breast cancer survivors need to be considered in future intervention development for cancer education.

RESUMO

Cancer survivors including Asian American breast cancer survivors have reported their high needs for help during their survivorship process. With the COVID-19 pandemic, the necessity of technology-based programs to address their needs for help without face-to-face interactions has been highlighted. The purpose of this randomized intervention study was to determine the efficacy of a technology-based program in reducing various types of needs for help among this specific population. This was a randomized clinical trial with repeated measures. A total of 199 participants were included in the data analysis. The recruitment settings included both online and offline communities/groups for Asian Americans. The needs for help were assessed using the Support Care Needs Survey-34 Short Form (SCNS) subscales measuring psychological, information, physical, support, and communication needs. Data analysis was conducted through an intent-to-treat approach. In the mixed effect models, psychological needs, information needs, physical needs, and communication needs decreased over time (P < .001). However, there were no significant group * time effects. Social support significantly mediated the effects of a technology-based intervention on psychological, information, and support needs at the pre-test and the post-1 month. This study supported significant decreases in the needs for help of Asian American breast cancer survivors by a technology-based intervention. Further studies are needed with other racial/ethnic groups of cancer survivors to confirm the efficacy of a technology-based intervention in reducing cancer survivors' needs for help during their survivorship process.

RESUMO

The number of health technology-based intervention studies has grown significantly. However, issues in the recruitment and retention for such studies, especially of Asian Americans, have rarely been discussed. The purpose of this paper was to discuss issues in the recruitment and retention of a specific group of Asian Americans-Korean American midlife women with depressive symptoms-into a technology-based intervention study using computers and mobile devices with a measurement device and to provide directions for future participant recruitment and retention in technology-based intervention studies. The written memos of research team members and the written records of research team meetings were analyzed using a content analysis. The issues in the recruitment and retention process included (1) low recruitment and retention rates; (2) the perceived long intervention period; (3) strict inclusion/exclusion criteria; (4) concerns related to the use of a measurement device; and (5) the perceived adequacy of monetary incentives. Based on the issues identified in the study, several suggestions are made for future recruitment and retention of racial/ethnic minorities in technology-based intervention studies (eg, appropriate intervention period, innovative and creative motivation strategies, acceptable measurement scales and devices, and adequate monetary reimbursement).

RESUMO

Chronic gut inflammation such as inflammatory bowel disease is believed to be associated with neurodegenerative diseases in humans. However, the direct evidence for and the underlying mechanism of this brain-gut interaction remain elusive. In this study, manganese-enhanced magnetic resonance imaging was used to assess functional brain activity from awake and freely moving mice with chronic colitis. Manganese ion uptake (indicative of Ca2+ influx into neuronal cells) and accumulation were reduced in the hippocampus of chronic colitis mice compared with control mice. Long-term memory declined and neuroinflammatory signals, including IL-1ß production and activation of caspase-1, caspase-11, and gasdermin, were induced. High-mobility group box 1 (HMGB1) levels were elevated both in the serum and in the hippocampus; however, lipopolysaccharide (LPS) levels remained at low levels without significant changes in these samples. The blood-brain barrier permeability was increased in chronic colitis mice. In the presence of LPS, HMGB1 treatment induced the activation of caspase-11 and gasdermin in the mouse microglial cell line SIM-A9. These findings suggest that HMGB1 released from the inflamed intestine may move to the brain through the blood circulatory system; in conjunction with a low level of endogenous LPS, elevated HMGB1 can subsequently activate caspase-mediated inflammatory responses in the brain.

RESUMO

N-Acetylserotonin (NAS) is an intermediate in the melatonin biosynthetic pathway. We investigated the anti-inflammatory activity of NAS by focusing on its chemical feature oxidizable to an electrophile. NAS was readily oxidized by reaction with HOCl, an oxidant produced in the inflammatory state. HOCl-reacted NAS (Oxi-NAS), but not NAS, activated the anti-inflammatory nuclear factor erythroid 2-related factor 2 (Nrf2)-heme oxygenase (HO)-1 pathway in cells. Chromatographic and mass analyses demonstrated that Oxi-NAS was the iminoquinone form of NAS and could react with N-acetylcysteine possessing a nucleophilic thiol to form a covalent adduct. Oxi-NAS bound to Kelch-like ECH-associated protein 1, resulting in Nrf2 dissociation. Moreover, rectally administered NAS increased the levels of nuclear Nrf2 and HO-1 proteins in the inflamed colon of rats. Simultaneously, NAS was converted to Oxi-NAS in the inflamed colon. Rectal NAS mitigated colonic damage and inflammation. The anticolitic effects were significantly compromised by the coadministration of an HO-1 inhibitor.

RESUMO

Scutellaria baicalensis Georgi (SBG), an herbal medicine with various biological activities, including anti-inflammatory, anticancer, antiviral, antibacterial, and antioxidant activities, is effective in treatment of colitis, hepatitis, pneumonia, respiratory infections, and allergic diseases. This herbal medicine consists of major active substances, such as baicalin, baicalein, wogonoside, and wogonin. Inflammatory bowel disease (IBD) comprises a group of inflammatory conditions of the colon and small intestine, with Crohn's disease and ulcerative colitis being the main types. IBD can lead to serious complications, such as increased risk of colorectal cancer (CRC), one of the most common cancers worldwide. Currently, there is no cure for IBD, and its incidence has been increasing over the past few decades. This review comprehensively summarizes the efficacy of SBG in IBD and CRC and may serve as a reference for future research and development of drugs for IBD and cancer treatment.

RESUMO

Atractylodin is a major compound in the rhizome of Atractylodes lancea, an oriental herbal medicine used for the treatment of gastrointestinal diseases, including dyspepsia, nausea, and diarrhea. Recent studies have shown that atractylodin exerts anti-inflammatory effects in various inflammatory diseases. Herein, we investigated the anti-colitis effects of atractylodin and its molecular targets. We determined the non-cytotoxic concentration of atractylodin (50 µM) using a cell proliferation assay in colonic epithelial cells. We found that pretreatment with atractylodin significantly inhibits tumor necrosis factor-α-induced phosphorylation of nuclear factor-κ-light-chain-enhancer of activated B in HCT116 cells. Through docking simulation analysis, luciferase assays, and in vitro binding assays, we found that atractylodin has an affinity for peroxisome proliferator-activated receptor alpha (PPARα). Daily administration of atractylodin (40 mg/kg) increased the survival rate of mice in a dextran sodium sulfate-induced colitis mouse model. Thus, atractylodin can be a good strategy for colitis therapy through inducing PPARα-dependent pathways.

RESUMO

To provide appropriate and adequate information and support for Asian American breast cancer survivors, it would be essential to identify risk groups among them to target in future cancer education interventions. In this secondary analysis, the characteristics of risk groups within Asian American breast cancer survivors who had low quality of life were identified using a decision tree analysis. For this analysis, only the pre-test data of 185 women from a parent study were selected. Multiple instruments including the Functional Assessment of Cancer Therapy Scale-Breast Cancer (FACT-B) were used in the parent study. The data were analyzed using descriptive and inferential statistics and decision tree analyses. The decision tree analyses showed six combined characteristics associated with lower quality of life scores than the total mean quality of life scores. For instance, the women with lower quality of life scores (than the total mean quality of life scores) had high perceived barriers (cut point = 1.84), low self-efficacy for coping (cut point = 81.50), and high global symptom distress (cut point = 2.27). Also, the characteristics linked to the lowest quality life scores were different depending on the dimensions of the quality of life. The characteristics associated with the quality of life of Asian American breast cancer survivors need to be considered in future education programs for this specific population.

RESUMO

PURPOSE: A culturally tailored technology-based cancer support program was recently developed and tested among Asian American breast cancer survivors. To explore future opportunities to sustain the program, the research team participated in the SPeeding Research-tested INTervention (SPRINT) program sponsored by the National Cancer Institute. The purpose of this discussion paper is to share the lessons that the research team gained from a customer discovery study through the SPRINT program. METHODS: During the SPRINT program, a total of 73 stakeholders were recruited through a snowball sampling across the globe. Semi-structured interviews were conducted for customer discovery through WebEX, phone calls, and in-person visits (50 in-person interviews, 4 phone interviews, and 19 WebEx interviews). All the interviews were recorded using audio-taping or writing memos. Also, the research team wrote memos on the issues/concerns related to the project during the interview process. Then, the transcripts and memos were analyzed using a content analysis to provide evidence for the lessons. RESULTS: The themes reflecting the lessons from the customer discovery study included (a) "who are the stakeholders"; (b) "depending on stakeholders"; (c) "what works or not"; (d) "personal versus family responsibilities"; and (e) "depending on countries' situations." CONCLUSION: These lessons could provide directions for future development and implementation of technology-based cancer support programs for Asian American breast cancer survivors.

RESUMO

Technology-based programs using computers and mobile devices are known to be effective in providing information and support to marginalized populations including immigrants. Yet, little is still known on the factors that may influence the effectiveness of technology-based programs in improving symptom experience, including immigration transition, especially among Asian American breast cancer survivors. This study aimed to identify the characteristics related to immigration transition that significantly affected the symptom distress changes by a technology-based information and coaching/support program among Asian American breast cancer survivors. This secondary analysis was conducted with the data from 102 Asian American breast cancer survivors from a randomized clinical trial in progress. Multiple instruments were used: the questions on background characteristics and immigration transition and the Memorial Symptom Assessment Scale-Short Form. The data were analyzed using repeated-measurement analyses and decision tree analyses. The mean changes in the symptoms distress scores were as follows: -0.12 (SD, 0.47) in the Global Distress Index scores; -0.08 (SD, 0.43) in the physical symptom distress scores; and -0.15 (SD, 0.65) in the psychological symptom distress scores. The characteristics with the highest impact on the symptom distress score changes included the immigration age for Global Distress Index and physical symptom distress score and the level of acculturation for psychological symptom distress score.

RESUMO

Lactobacillus plantarum (L. plantarum) is a probiotic that has emerged as novel therapeutic agents for managing various diseases, such as cancer, atopic dermatitis, inflammatory bowel disease, and infections. In this study, we investigated the potential mechanisms underlying the anticancer effect of the metabolites of L. plantarum. We cultured L. plantarum cells to obtain their metabolites, created several dilutions, and used these solutions to treat human colonic Caco-2 cells. Our results showed a 10% dilution of L. plantarum metabolites decreased cell viability and reduced the expression of autophagy-related proteins. Moreover, we found co-treatment with L. plantarum metabolites and chloroquine, a known autophagy inhibitor, had a synergistic effect on cytotoxicity and downregulation of autophagy-related protein expression. In conclusion, we showed the metabolites from the probiotic, L. plantarum, work synergistically with chloroquine in killing Caco-2 cells and downregulating the expression of autophagy-related proteins, suggesting the involvement of autophagy, rather than apoptosis, in their cytotoxic effect. Hence, this study provides new insights into new therapeutic methods via inhibiting autophagy.

RESUMO

BACKGROUND: The prevalence of depression is higher among midlife women, and they have less control over their diabetes during the menopausal transition. However, there is limited evidence on the association between type 2 diabetes mellitus and depression among Korean women in their midlife. This study aimed to examine the association between type 2 diabetes mellitus and depression and explore the levels of awareness and treatment of depression among Korean midlife women with T2DM. METHODS: This is a cross-sectional analysis study conducted using data from the Korea National Health and Nutrition Examination Surveys of 2014, 2016, and 2018. Korean women aged 40-64 years who randomly participated in the surveys were included, and 4,063 midlife women were selected as study participants. The diabetes progression status of the participants was classified into diabetes, pre-diabetes, and non-diabetes. Furthermore, the Patient Health Questionnaire-9 was used for screening depression. Participants' awareness rate, treatment rate among incident cases of depression, and treatment rate among awareness cases of depression were also analyzed. For data analysis, the Rao-Scott χ2 test, multiple logistic regression, and linear regression were conducted using SAS 9.4 software program. RESULTS: The prevalence of depression significantly differed between diabetes, pre-diabetes, and non-diabetes groups. However, depression awareness, treatment/incident, and treatment/awareness rates did not differ statistically between the diabetes progression status groups. Compared to the non-diabetes group, diabetes group had a higher odds ratio of depression after adjusting for general and health-related factors. Thus, the diabetes group had significantly higher PHQ-9 scores than the non-diabetes group after adjusting for covariates. CONCLUSIONS: Women in their midlife who have type 2 diabetes mellitus tend to have higher levels of depressive symptoms and are at risk of depression. However, we found no significant differences between diabetes and non-diabetes regarding the awareness and treatment rates of depression in South Korea. We recommend that future studies focus on developing clinical practice guidelines aimed at additional screening and intervention for depression in midlife women with type 2 diabetes mellitus to ensure prompt treatment and improved outcomes.

RESUMO

Autotaxin (ATX) converts lysophosphatidylcholine and sphingosyl-phosphorylcholine into lysophosphatidic acid and sphingosine 1-phosphate, respectively. Despite the pivotal function of ATX in lipid metabolism, mechanisms by which ATX regulates immune and inflammatory disorders remain elusive. Here, using myeloid cell lineage-restricted Atx knockout mice, we show that Atx deficiency disrupts membrane microdomains and lipid rafts, resulting in the inhibition of Toll-like receptor 4 (TLR4) complex formation and the suppression of adaptor recruitment, thereby inhibiting TLR4-mediated responses in macrophages. Accordingly, TLR4-induced innate immune functions, including phagocytosis and iNOS expression, are attenuated in Atx-deficient macrophages. Consequently, Atx-/- mice exhibit a higher bacterial prevalence in the intestinal mucosa compared to controls. When combined with global Il10-/- mice, which show spontaneous colitis due to the translocation of luminal commensal microbes into the mucosa, myeloid cell lineage-restricted Atx knockout accelerates colitis development compared to control littermates. Collectively, our data reveal that Atx deficiency compromises innate immune responses, thereby promoting microbe-associated gut inflammation.

RESUMO

BACKGROUND: Metabolic syndrome is known as a lifestyle disease that results from poor health behaviors. Yet, little is known about the subgroups of midlife women with distinct health behavior profiles who are at risk for developing metabolic syndrome. PURPOSE: This study aims to identify latent subgroups of midlife women with distinct health behavior profiles (physical activity, alcohol, diet, and smoking), to describe the characteristics of latent subgroups, and to examine the association between latent class membership and future development of metabolic syndrome. METHOD: This is a secondary data analysis using baseline and follow-up data from years 1, 3, 5, and 7 (N = 3,100) from the Study of Women's Health Across the Nation (SWAN). Latent class analysis was used to identify latent subgroups of midlife women based on their distinct health behavior profiles. Bivariate and multiple logistic regression was conducted to examine the individual characteristics of each latent subgroup and its association with the future development of metabolic syndrome. RESULT: A 4-class model was selected: Class 1 (Healthy), Class 2 (Healthy except alcohol), Class 3 (Healthy except diet), and Class 4 (Unhealthy). Significant differences in individual characteristics were found among the four latent classes (p < .001). The regression analysis found that Class 2 had lower odds of developing metabolic syndrome at all future visits with statistical significance reached at visit 3 (p < .05) while Class 4 had higher odds of developing metabolic syndrome at all visits except visit 3 when both compared to Class 1. CONCLUSION: Clinicians should use the study findings to offer personalized approach to promote healthy behaviors and to guide future development of health promotion programs for midlife women.

RESUMO

BACKGROUND: Midlife perimenopausal and postmenopausal women with metabolic syndrome experience multiple symptoms concurrently. OBJECTIVE: The study objectives were to examine the relationship among symptoms through network visualization and identify and compare symptom clusters and key symptoms across symptom occurrence and symptom severity dimensions in midlife perimenopausal and postmenopausal women with and without metabolic syndrome. METHODS: Cross-sectional data from the Study of Women's Health Across the Nation (Visit 5) were used for analysis. A machine-learning-based network analysis and the Walktrap algorithm were used to fulfill the study objectives. RESULTS: The number and types of symptom clusters differed between the groups. Midlife perimenopausal and postmenopausal women with metabolic syndrome experienced the psychological/somatic/genital cluster (key symptom: frequent mood change), the sleep/urinary cluster (sleep disturbance), and the vasomotor cluster (cold sweat) in the symptom occurrence dimension and the psychological/somatic/sexual cluster (anxiety), the sleep/urinary cluster (sleep disturbance), and the vasomotor/genital cluster (night sweat) in the symptom severity dimension. In contrast, midlife perimenopausal and postmenopausal women without metabolic syndrome experienced the psychological cluster (anxiety), the sleep/somatic/genitourinary cluster (sleep disturbance), and the vasomotor cluster (night sweat) in the symptom occurrence dimension and the psychological/somatic cluster (anxiety), the sleep/urinary cluster (sleep disturbance), the vasomotor cluster (night sweat), and the sexual/genital cluster (vaginal dryness) in the symptom severity dimension. DISCUSSION: The study findings may serve as a knowledge basis for effective assessment and management of symptom clusters and key symptoms in clinical settings and provide directions for future development of targeted symptom management interventions.

RESUMO

Resveratrol (3,5,4'-trihydroxy-trans-stilbene), a polyphenol found in grapes, red wine, peanuts, and apples, has been reported to exhibit a wide range of biological and pharmacological properties. In addition, resveratrol has been reported to intervene in multiple stages of carcinogenesis. It has also been known to kill several human cancer cells through programmed cell death (PCD) mechanisms such as apoptosis, autophagy, and necroptosis. However, resveratrol has limitations in its use as an anticancer agent because it is susceptible to photoisomerization owing to its unstable double bond, short half-life, and is rapidly metabolized and eliminated. Trans-(E)-resveratrol is nontoxic, and has several biological and pharmacological activities. However, little is known about the pharmacological properties of the photoisomerized cis-(Z)-resveratrol. Therefore, many studies on resveratrol derivatives and analogues that can overcome the shortcomings of resveratrol and increase its anticancer activity are underway. This review comprehensively summarizes the literature related to resveratrol-induced PCD, such as apoptosis, autophagy, necroptosis, and the development status of synthetic resveratrol derivatives and analogues as novel anticancer drugs.

RESUMO

Bile acids are major signaling molecules that play a significant role as emulsifiers in the digestion and absorption of dietary lipids. Bile acids are amphiphilic molecules produced by the reaction of enzymes with cholesterol as a substrate, and they are the primary metabolites of cholesterol in the body. Bile acids were initially considered as tumor promoters, but many studies have deemed them to be tumor suppressors. The tumor-suppressive effect of bile acids is associated with programmed cell death. Moreover, based on this fact, several synthetic bile acid derivatives have also been used to induce programmed cell death in several types of human cancers. This review comprehensively summarizes the literature related to bile acid-induced programmed cell death, such as apoptosis, autophagy, and necroptosis, and the status of drug development using synthetic bile acid derivatives against human cancers. We hope that this review will provide a reference for the future research and development of drugs against cancer.

RESUMO

Sirtuins (SIRTs), which are nicotinamide adenine dinucleotide-dependent class III histone deacetylases, regulate cell division, survival, and senescence. Although sirtinol, a synthetic SIRT inhibitor, is known to exhibit antitumor effects, its mechanism of action is not well understood. Therefore, we aimed to assess the anticancer effects and underlying mechanism of MHY2245, a derivative of sirtinol, in HCT116 human colorectal cancer cells in vitro. Treatment with MHY2245 decreased SIRT1 activity and caused DNA damage, leading to the upregulation of p53 acetylation, and increased levels of p53, phosphorylation of H2A histone family member X, ataxia telangiectasia and Rad3-related kinase, checkpoint kinase 1 (Chk1), and Chk2. The level of the breast cancer type 1 susceptibility protein was also found to decrease. MHY2245 induced G2/M phase cell cycle arrest via the downregulation of cyclin B1, cell division cycle protein 2 (Cdc2), and Cdc25c. Further, MHY2245 induced HCT116 cell death via apoptosis, which was accompanied by internucleosomal DNA fragmentation, decreased B-cell lymphoma 2 (Bcl-2) levels, increased Bcl-2-asscociated X protein levels, cleavage of poly(ADP-ribose) polymerase, and activation of caspases -3, -8, and -9. Overall, MHY2245 induces cell cycle arrest, triggers apoptosis through caspase activation, and exhibits DNA damage response-associated anticancer effects.

RESUMO

Through a decision tree analysis, this study aimed to determine the characteristics of Asian American breast cancer survivors who had higher decreases in their need for information by a technology-based information and coaching/support program compared with their counterparts. This is a part of a larger randomized controlled trial; only the data from 99 Asian American breast cancer survivors were used for this analysis. The measurement scales included the Memorial Symptom Assessment Scale-Short Form, the Cancer Behavior Inventory, the Questions on Attitudes, Subjective Norm, Perceived Behavioral Control and Behavioral Intention, and the Supportive Care Needs Survey-Short Form 34. The data analysis was done using t-tests, chi-square tests, repeated measurement analyses, and a decision tree analysis. The information needs scores of all the participants decreased during the 3-month intervention period (p < .005). However, only the intervention group had statistically significant decreases in the information needs scores during the 3 months (dif. = - 8.545; p < .005). Those with low social influence scores and high self-efficacy scores had significantly larger decreases in their information needs scores compared with the average change scores (100%, p < 01). Asian American breast cancer survivors with low social influences and high self-efficacy would highly benefit from a technology-based intervention for their need for information.

RESUMO

Using a decision tree analysis, this study aimed to identify the characteristics of the groups within Asian American breast cancer survivors whose symptom distress scores were effectively improved by a technology-based program. This was a secondary analysis of the data from an ongoing randomized controlled trial among 115 Asian American breast cancer survivors. The instruments were questions on background factors; the Memorial Symptom Assessment Scale-Short Form; the Cancer Behavior Inventory; the Questions on Attitudes, Subjective Norm, Perceived Behavioral Control, and Behavioral Intention; and the Supportive Care Needs Survey-Short Form 34. The data were analyzed using chi-square tests, t tests, repeated measurement analyses, and decision tree analyses. The decrease in the global distress index scores was the largest (1.253 points) among those with high psychological support needs. The decrease in the physical symptom distress scale scores was the largest (1.133 points) among those with high physical and daily living support needs who had a short US residence period and who were young. The decrease in the psychological symptom distress scores was the largest (1.511) among those with high psychological support needs. The findings suggest several characteristics of the groups within Asian American breast cancer survivors whose symptom distress could be highly improved by a technology-based intervention.
