RESUMEN

Phytopathogens pose a severe threat to agriculture and strengthening the plant defense response is an important strategy for disease control. Here, we report that AtRAV1, an AP2 and B3 domain-containing transcription factor, is required for basal plant defense in Arabidopsis thaliana. The atrav1 mutant lines demonstrate hyper-susceptibility against fungal pathogens (Rhizoctonia solani and Botrytis cinerea), whereas AtRAV1 overexpressing lines exhibit disease resistance against them. Enhanced expression of various defense genes and activation of mitogen-activated protein kinases (AtMPK3 and AtMPK6) are observed in the R. solani infected overexpressing lines, but not in the atrav1 mutant plants. An in vitro phosphorylation assay suggests AtRAV1 to be a novel phosphorylation target of AtMPK3. Bimolecular fluorescence complementation and yeast two-hybrid assays support physical interactions between AtRAV1 and AtMPK3. Overexpression of the native as well as phospho-mimic but not the phospho-defective variant of AtRAV1 imparts disease resistance in the atrav1 mutant A. thaliana lines. On the other hand, overexpression of AtRAV1 fails to impart disease resistance in the atmpk3 mutant. These analyses emphasize that AtMPK3-mediated phosphorylation of AtRAV1 is important for the elaboration of the defense response in A. thaliana. Considering that RAV1 homologs are conserved in diverse plant species, we propose that they can be gainfully deployed to impart disease resistance in agriculturally important crop plants. Indeed, overexpression of SlRAV1 (a member of the RAV1 family) imparts disease tolerance against not only fungal (R. solani and B. cinerea), but also against bacterial (Ralstonia solanacearum) pathogens in tomato, whereas silencing of the gene enhances disease susceptibility.

RESUMEN

OBJECTIVE: Androgen deprivation therapy (ADT) is a common treatment for prostate cancer (PCa), with increasing numbers of men on ADT for longer. Limited evidence suggests ADT impacts cognition. This study addressed gaps in the literature by focusing on older men with PCa and assessing ADT usage longer than 1 year. METHODS: This study of 133 men ≥65 years of age with PCa included two groups: (1) men on ADT for 1-3 years (ADT-exposed), and (2) a comparison group of men with PCa not on ADT (ADT-unexposed). Group comparisons on individual neuropsychological test scores are reported, as well as effect sizes (Cohen's d). RESULTS: Half (n = 67) of the sample was ADT-exposed and half (n = 66) were unexposed. The average age was 72 years, most were White, and over 50% had at least secondary education. There were no statistically significant differences between groups by age, race, or education. Unadjusted analyses showed the ADT-exposed group, compared with the ADT-unexposed group, performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.01 to <0.01), verbal recall (d = 0.33-0.54, p = 0.06 to <0.01), and possible effects in visuospatial construction (d = 0.33, p = 0.08 to 0.06). When controlling for age and education, similar patterns emerged. The ADT exposed-group performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.06 to 0.03) and verbal recall (d = 0.33-0.54, p = 0.11 to 0.03), and possible effects in visuospatial construction d = 0.33, p = 0.18 to 0.13. CONCLUSIONS: This study suggests long-term ADT exposure impacts verbal learning, verbal recall, and possibly visuospatial abilities in older men (≥65) with PCa. The potential cognitive effects of ADT should be discussed with older patients considering long-term use of ADT.

RESUMEN

Evodiamine is a bioactive alkaloid extracted from the Evodia rutaecarpa plant. It has various pharmacological effects including anti-cancer, anti-bacterial, anti-obesity, anti-neurodegenerative, anti-depressant, and cardiac protective properties. Evodiamine demonstrates potent anti-cancer activity by inhibiting the proliferation of cancer cells in vitro and in vivo. Despite the health-promoting properties of evodiamine, its clinical use is hindered by low water solubility, poor bioavailability, and toxicity. Thus, there is a need to develop alternative drug delivery systems for evodiamine to enhance its solubility, permeability, and stability, as well as to facilitate targeted, prolonged, and controlled drug release. Nanocarriers can increase the therapeutic potential of evodiamine in cancer therapy while reducing adverse side effects. To date, numerous attempts have been made through the development of smart nanocarriers to overcome the drawbacks of evodiamine. This review focuses on the pharmacological applications, anti-cancer mechanisms, and limitations of evodiamine. Various nanocarriers, including lipid-based nanoparticles, polymeric nanoparticles, cyclodextrins, and so forth, have been discussed extensively for evodiamine delivery. Nano-drug delivery systems could increase the solubility, bioavailability, stability, and therapeutic efficacy of evodiamine. This review aims to present a comprehensive and critical evaluation of several nano-formulations of evodiamine for cancer therapy. © 2024 Society of Chemical Industry.

RESUMEN

BACKGROUND: Mangifera indica L. (mango), a medicinal plant rich in biologically active compounds, has potential to be used in disease-preventing and health-promoting products. The present investigation reveals and uncovers bioactive metabolites with remarkable therapeutic efficiency from mango (family: Anacardiaceae) seeds. RESULTS: Biological activity was determined by antimicrobial, antioxidant and anticancer assays, and metabolite profiling was performed on gas chromatography coupled to quadrupole time-of-flight mass spectrometry (GC-QTOF-MS) and liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) platforms. Validation of active metabolites was carried out by in silico molecular docking (Molinspiration Cheminformatics Server and PASS). Extracted and identified metabolites were screened; 54 compounds associated with various groups were selected for the in silico interaction study. CONCLUSIONS: Molecular docking revealed lead molecules with a potential binding energy score, efficacy and stable modulation with a selected protein domain. Investigation, directed by in vitro and in silico analysis, confirms mango seeds as an excellent source of potential metabolites as a therapeutic agent. © 2024 Society of Chemical Industry.

RESUMEN

BACKGROUND: Immune activation/inflammation markers (immune markers) were tested to explain differences in neurocognition among older breast cancer survivors versus noncancer controls. METHODS: Women >60 years old with primary breast cancer (stages 0-III) (n = 400) were assessed before systemic therapy with frequency-matched controls (n = 329) and followed annually to 60 months; blood was collected during annual assessments from 2016 to 2020. Neurocognition was measured by tests of attention, processing speed, and executive function (APE). Plasma levels of interleukin-6 (IL-6), IL-8, IL-10, tumor necrosis factor α (TNF-α), and interferon γ were determined using multiplex testing. Mixed linear models were used to compare results of immune marker levels by survivor/control group by time and by controlling for age, racial/ethnic group, cognitive reserve, and study site. Covariate-adjusted multilevel mediation analyses tested whether survivor/control group effects on cognition were explained by immune markers; secondary analyses examined the impact of additional covariates (e.g., comorbidity and obesity) on mediation effects. RESULTS: Participants were aged 60-90 years (mean, 67.7 years). Most survivors had stage I (60.9%) estrogen receptor-positive tumors (87.6%). Survivors had significantly higher IL-6 levels than controls before systemic therapy and at 12, 24, and 60 months (p ≤ .001-.014) but there were no differences for other markers. Survivors had lower adjusted APE scores than controls (p < .05). Levels of IL-6, IL-10, and TNF-α were related to APE, with IL-6 explaining part of the relationship between survivor/control group and APE (p = .01). The magnitude of this mediation effect decreased but remained significant (p = .047) after the consideration of additional covariates. CONCLUSIONS: Older breast cancer survivors had worse long-term neurocognitive performance than controls, and this relationship was explained in part by elevated IL-6.

RESUMEN

BACKGROUND: Cancer and its treatments may accelerate aging in survivors; however, research has not examined epigenetic markers of aging in longer term breast cancer survivors. This study examined whether older breast cancer survivors showed greater epigenetic aging than noncancer controls and whether epigenetic aging related to functional outcomes. METHODS: Nonmetastatic breast cancer survivors (n = 89) enrolled prior to systemic therapy and frequency-matched controls (n = 101) ages 62 to 84 years provided two blood samples to derive epigenetic aging measures (Horvath, Extrinsic Epigenetic Age [EEA], PhenoAge, GrimAge, Dunedin Pace of Aging) and completed cognitive (Functional Assessment of Cancer Therapy-Cognitive Function) and physical (Medical Outcomes Study Short Form-12) function assessments at approximately 24 to 36 and 60 months after enrollment. Mixed-effects models tested survivor-control differences in epigenetic aging, adjusting for age and comorbidities; models for functional outcomes also adjusted for racial group, site, and cognitive reserve. RESULTS: Survivors were 1.04 to 2.22 years biologically older than controls on Horvath, EEA, GrimAge, and DunedinPACE measures (p = .001-.04) at approximately 24 to 36 months after enrollment. Survivors exposed to chemotherapy were 1.97 to 2.71 years older (p = .001-.04), and among this group, an older EEA related to worse self-reported cognition (p = .047) relative to controls. An older epigenetic age related to worse physical function in all women (p < .001-.01). Survivors and controls showed similar epigenetic aging over time, but Black survivors showed accelerated aging over time relative to non-Hispanic White survivors. CONCLUSION: Older breast cancer survivors, particularly those exposed to chemotherapy, showed greater epigenetic aging than controls that may relate to worse outcomes. If replicated, measurement of biological aging could complement geriatric assessments to guide cancer care for older women.

RESUMEN

BACKGROUND: Older cancer survivors are at risk for cognitive decline. Physical activity can improve cognition, and better cognitive function may facilitate greater physical activity. PURPOSE: We examined the potential bidirectional relationship between cognitive function and physical activity in older breast cancer survivors and controls. METHODS: The sample included women with newly diagnosed, nonmetastatic breast cancer (n = 395) and women without cancer (n = 374) ages 60-98. Participants were recruited as part of a larger multisite study, assessed prior to systemic therapy, and followed yearly for 36 months. Attention, processing speed, and executive function was measured using six neuropsychological tests, self-reported cognitive function using the Perceived Cognitive Impairments subscale of the Functional Assessment of Cancer Therapy-Cognitive Function , and physical activity using the International Physical Activity Questionnaire-Short Form. Separate random intercepts cross-lagged panel models were used to examine the between- and within-person effects for survivors and controls, controlling for age, education, and study site. RESULTS: Survivors reported significantly less physical activity than controls at baseline (1,284.92 vs. 2,085.98 MET min/week, p < .05). When survivors reported higher activity, they simultaneously had better objective cognition at 12 months (ß = 0.24, p = .04) and reported better perceived cognition at 12 and 24 months (ß = 0.25, p = .03), but this relationship was not seen in controls. Cognition did not predict subsequent physical activity or vice versa in either group. CONCLUSIONS: Cognition and physical activity are cross-sectionally associated in survivors, but the expected prospective relationships were not found.


Physical activity may improve cognitive function for older cancer survivors; however, cognitive function may also affect the ability to organize oneself to be physically active. We examined this potential bidirectional relationship in a sample of 395 women with newly diagnosed, nonmetastatic breast cancer, and 374 noncancer controls. These women completed cognitive tests and surveys yearly for 36 months. Surveys included their subjective cognitive function and physical activity. We examined the relationships between cognitive function (both objective and subjective) and physical activity over time (baseline, 12, 24, and 36 months). We found that when cancer survivors reported higher physical activity, they had better objective cognitive function at 12 months, and they reported better subjective cognitive function at 12 and 24 months. However, physical activity did not predict cognitive function at later time points, and cognitive function did not predict physical activity at later time points. In controls, better subjective cognitive function was related to higher physical activity overall, but there were not relationships over time or at specific time points. This was an observational study; therefore, future research should consider the potential impact of cognitive function when older cancer survivors are attempting to increase their physical activity.

RESUMEN

PURPOSE: Older cancer patients are susceptible to long-term effects of chemotherapy, including cancer-related cognitive decline and impairments to quality of life. Taxane-based chemotherapies are associated with physical declines among older women and may negatively impact cognitive performance. We sought to examine whether changes in objective and subjective measures of cognitive performance and well-being differ among older breast cancer survivors as a function of taxane-based chemotherapy treatment regimens. METHODS: Individual-level data were pooled and harmonized from two large prospective studies of older (greater than 60 years) breast cancer survivors. Assessments were conducted prior to systemic therapy and up to 36 months after. Cognitive performance was assessed with objective (working memory, processing speed, and executive functions) and subjective tests and physical, emotional, and functional well-being were also assessed. RESULTS: One hundred and sixty-seven (M age = 67.3 years) women with 116 receiving chemotherapy with taxanes and 51 without taxanes contributed data. Declines in subjective cognition for both groups were significant between pre-treatment and 12-month follow-up. Significant improvements were seen on a measure of objective cognition (working memory) from 12 to 36 months. Measures of well-being improved from prior to systemic therapy to 12 months. Longitudinal changes across all measures did not vary as a function of receipt of taxane-based treatment. CONCLUSION: Older women who received treatment with taxanes did not have greater declines in cognitive performance or well-being than women receiving other chemotherapy regimens. Despite older cancer survivors being at greater risk for negative outcomes, treatment with taxane-based chemotherapies does not appear to exacerbate these health consequences.

RESUMEN

PURPOSE: Tumor features associated with aggressive cancers may affect cognition prior to systemic therapy. We evaluated associations of cognition prior to adjuvant therapy and tumor aggressivity in older breast cancer patients. METHODS: Women diagnosed with non-metastatic breast cancer (n = 705) ages 60-98 were enrolled from August 2010-March 2020. Cognition was measured post-surgery, pre-systemic therapy using self-reported (FACT-Cog Perceived Cognitive Impairment [PCI]) and objective tests of attention, processing speed, and executive function (APE domain) and learning and memory [LM domain]. Linear regression tested associations of pre-treatment tumor features and cognition, adjusting for age, race, and study site. HER2 positivity and higher stage (II/III vs. 0/I) were a priori predictors of cognition; in secondary analyses we explored associations of other tumor features and cognitive impairment (i.e., PCI score < 54 or having 2 tests < 1.5 SD or 1 test < 2 SD from the mean APE or LM domain score). RESULTS: HER2 positivity and the hormone receptor negative/HER2 + molecular subtype were associated with lower adjusted mean self-reported cognition scores and higher impairment rates (p values < .05). Higher stage of disease was associated with lower objective performance in APE. Other tumor features were associated with cognition in unadjusted and adjusted models, including larger tumor size and lower PCI scores (p = 0.02). Tumor features were not related to LM. CONCLUSIONS: Pre-adjuvant therapy cognition was associated with HER2 positivity and higher stage of disease and other features of aggressive tumors. Additional research is needed to confirm these results and assess potential mechanisms and clinical management strategies.

RESUMEN

OBJECTIVE: The aim was to develop matrix metalloproteinase 1 (MMP1) responsive nanoparticle system for the delivery of 5-fluorouracil (5Fu) anticancer drug. SIGNIFICANCE: The MMP1 in the cancer microenvironment-induced drug release have the advantage of targeted drug release and reduce the distribution of drug to the healthy tissues. METHOD: G5 poly(amidoamine) (PAMAM) dendrimer (G5)-coated gold nanoparticles (G5AuNP) were synthesized and loaded with 5Fu. The drug-loaded nanoparticles were further coated with collagen I (Col-I) peptide, which is a substrate for MMP1 enzyme (Col-I 5Fu@G5AuNP). RESULT: The nanoparticles were highly monodispersed with a particle size of 30 nm and showed high drug encapsulation efficiency. The release of drug from the nanoparticles in HEPES buffer pH 7.4 was faster, higher and better controlled when incubated with MMP1 enzyme. The half-maximum inhibitory concentration for Col-I 5Fu@G5AuNP was eight times lower than the 5Fu against MCF-7, suggesting the improved delivery and anticancer activity of 5Fu after encapsulation in the developed enzyme-responsive nanocarrier system. The computed tomography (CT) X-ray attenuation of Col-I@G5AuNP showed a good contrasting property. CONCLUSION: The formulation Col-I 5Fu@G5AuNP has improved anticancer activity than free drug and the CT imaging results are promising for its theranostic applications for breast cancer treatment.

RESUMEN

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had wide-ranging health effects and increased isolation. Older with cancer patients might be especially vulnerable to loneliness and poor mental health during the pandemic. METHODS: The authors included active participants enrolled in the longitudinal Thinking and Living With Cancer study of nonmetastatic breast cancer survivors aged 60 to 89 years (n = 262) and matched controls (n = 165) from 5 US regions. Participants completed questionnaires at parent study enrollment and then annually, including a web-based or telephone COVID-19 survey, between May 27 and September 11, 2020. Mixed-effects models were used to examine changes in loneliness (a single item on the Center for Epidemiologic Studies-Depression [CES-D] scale) from before to during the pandemic in survivors versus controls and to test survivor-control differences in the associations between changes in loneliness and changes in mental health, including depression (CES-D, excluding the loneliness item), anxiety (the State-Trait Anxiety Inventory), and perceived stress (the Perceived Stress Scale). Models were adjusted for age, race, county COVID-19 death rates, and time between assessments. RESULTS: Loneliness increased from before to during the pandemic (0.211; P = .001), with no survivor-control differences. Increased loneliness was associated with worsening depression (3.958; P < .001) and anxiety (3.242; P < .001) symptoms and higher stress (1.172; P < .001) during the pandemic, also with no survivor-control differences. CONCLUSIONS: Cancer survivors reported changes in loneliness and mental health similar to those reported by women without cancer. However, both groups reported increased loneliness from before to during the pandemic that was related to worsening mental health, suggesting that screening for loneliness during medical care interactions will be important for identifying all older women at risk for adverse mental health effects of the pandemic.

RESUMEN

OBJECTIVE: Although there is enthusiasm for identifying and treating psychosocial problems in childhood cancer patients, there are few validated instruments to help providers identify at-risk children for further assessment. The study objective was to evaluate the sensitivity and specificity of the self-report pediatric Distress Thermometer Rating Scale (Peds DTRS) in childhood cancer survivors and identify a threshold score to help providers classify pediatric patients. METHODS: We evaluated 54 children 7-17 years old using 178 Peds DTRS longitudinal data points from the cohort that was used for the original pediatric adaptation of the DTRS. We compared Peds DTRS scores against two established standardized measures using a generalized linear mixed model to deal with the dependency in the longitudinal data to estimate ROC curves and related statistics. RESULTS: Results indicate that a score of 3 is a reasonable cutoff to identify distress with children 7-17 years old. This cutoff yielded high sensitivity (87.0%) and specificity (79.7%) using the PedsQL Emotional Domain score as the standard. Similar results were obtained using the CDI as the standard, but we are cautious as very few CDI scores reached the cutoff criterion. Exploratory analysis highlighted clinical factors that correlate with increased distress measured using the Peds DTRS. CONCLUSIONS: The Peds DTRS is a very brief, convenient, and rapid screening tool for global distress in children. Further investigation of the Peds DTRS and other tools can improve the ability of providers to prevent and treat the negative emotional consequences of cancer and improve the quality of survivorship.

RESUMEN

BACKGROUND: Cognitive impairment in survivors of blood or bone marrow transplantation (BMT) is well documented. However, to the authors' knowledge, the clinical relevance of self-endorsed cognitive problems and their relation to objectively assessed cognitive impairment is not known. METHODS: The authors assessed cognitive impairment in 378 BMT recipients (median age, 52.2 years, 40% of whom were female and 68% of whom were non-Hispanic white) and 98 healthy controls at 5 predetermined time points: at baseline (before BMT) and at 6 months, 1 year, 2 years, and 3 years after BMT. Self-endorsed cognitive problems were evaluated using the Neuropsychological Impairment Scale (NIS) and correlated with a standardized 2-hour battery of objective cognitive testing at each time point. The authors examined the magnitude of difference in self-endorsed cognitive problems between BMT recipients and healthy controls, and the rate of change in scores over time. Multivariable analyses were used to identify clinical and/or demographic variables associated with self-endorsed cognitive problems. The authors also examined the association between cognitive impairment and returning to work after BMT. RESULTS: Compared with healthy controls, BMT recipients endorsed more cognitive problems (P < .001) at all time points, and the rate of change in NIS scores was found to be significantly greater in BMT recipients. Fatigue was associated with greater endorsement of cognitive problems at 1 year after BMT (odds ratio, 4.23; 95% CI, 2.1-8.3 [P < .001]). Overall, there was a statistically significant, modest correlation noted between self-endorsed cognitive problems and objective cognitive impairment (range, 0.401-0.445 [P ≤ .01]). Higher self-endorsed cognitive problems were associated with a 3.7-fold (P = .02) higher odds of not returning to work at 3 years after BMT. CONCLUSIONS: The results of the current study demonstrated that self-endorsed cognitive problems can help to identify vulnerable patient subpopulations for detailed cognitive assessment and possible cognitive remediation.

RESUMEN

BACKGROUND: Little is known about longitudinal symptom burden, its consequences for well-being, and whether lifestyle moderates the burden in older survivors. METHODS: The authors report on 36-month data from survivors aged ≥60 years with newly diagnosed, nonmetastatic breast cancer and noncancer controls recruited from August 2010 through June 2016. Symptom burden was measured as the sum of self-reported symptoms/diseases as follows: pain (yes or no), fatigue (on the Functional Assessment of Cancer Therapy [FACT]-Fatigue scale), cognitive (on the FACT-Cognitive scale), sleep problems (yes or no), depression (on the Center for Epidemiologic Studies Depression scale), anxiety (on the State-Trait Anxiety Inventory), and cardiac problems and neuropathy (yes or no). Well-being was measured using the FACT-General scale, with scores from 0 to 100. Lifestyle included smoking, alcohol use, body mass index, physical activity, and leisure activities. Mixed models assessed relations between treatment group (chemotherapy with or without hormone therapy, hormone therapy only, and controls) and symptom burden, lifestyle, and covariates. Separate models tested the effects of fluctuations in symptom burden and lifestyle on function. RESULTS: All groups reported high baseline symptoms, and levels remained high over time; differences between survivors and controls were most notable for cognitive and sleep problems, anxiety, and neuropathy. The adjusted burden score was highest among chemotherapy-exposed survivors, followed by hormone therapy-exposed survivors versus controls (P < .001). The burden score was related to physical, emotional, and functional well-being (eg, survivors with lower vs higher burden scores had 12.4-point higher physical well-being scores). The composite lifestyle score was not related to symptom burden or well-being, but physical activity was significantly associated with each outcome (P < .005). CONCLUSIONS: Cancer and its treatments are associated with a higher level of actionable symptoms and greater loss of well-being over time in older breast cancer survivors than in comparable noncancer populations, suggesting the need for surveillance and opportunities for intervention.

RESUMEN

BACKGROUND: Children with brain tumor or acute leukemia are at risk for neurotoxic side effects associated with their cancer therapies. These long-term deficits include poor health-related quality of life (HRQOL) in school and lower educational achievement. Although social-ecological factors may impact these outcomes, it is not known which factors play a role. Our objective was to evaluate the factors affecting school HRQOL in Hispanic childhood cancer survivors, an important at-risk group. PROCEDURE: Multivariable regression analyses examined whether selected social-ecological factors contribute toward suboptimal school HRQOL in 73 Hispanic children treated with central nervous system (CNS)-directed cancer therapies after accounting for effects associated with established cancer-related risk factors. RESULTS: Consistent with expectations from prior research, in our multivariate analysis, the cancer-related factors of having a brain tumor diagnosis and being younger at cancer diagnosis were significant predictors of reduced parent-reported school HRQOL (F(2,65) = 5.46, P < .01) and accounted for 14% of the variance. Adding the social-ecological variables of parent education, child motivation, and parental knowledge accounted for an additional 25% of the variance in school HRQOL, where higher levels were associated with better child school HRQOL. Parenting knowledge was a contributor even after controlling for effects associated with the other variables in the model (F(1,62) = 4.88, P < .05). CONCLUSIONS: Cancer survivorship care should incorporate parent education interventions to enhance the child's school functioning, particularly for Hispanic childhood cancer survivors from predominantly Spanish-speaking families. Future research should consider other at-risk groups and incorporate social-ecological indicators to predict HRQOL outcomes.

RESUMEN

OBJECTIVE: Survivors of childhood leukemia, especially those from low socioeconomic status households, often experience persistent neurocognitive and academic impairment. This study adapted an existing parent training intervention to improve outcomes for low-acculturated, Spanish-speaking Latino parents of children with leukemia and pilot tested that intervention for feasibility. METHODS: Semistructured interviews were conducted with a focus group of 20 Latino parents of children treated for leukemia. Ten Latino families participated in a pilot study of the adapted parenting intervention, consisting of eight sessions over 6 months. RESULTS: Focus groups revealed that parents unanimously supported a parenting intervention but barriers to participation included time constraints, transportation issues, and anxiety in the hospital environment. The parents also highlighted cultural factors that could contribute to the health disparity, such as lack of knowledge and efficacy in facilitating their child's progress with learning and school. In the pilot study, adherence was 90%, establishing feasibility, and the adapted intervention was considered beneficial. The median parenting efficacy scores improved from preintervention to postintervention (median 3.40 vs. 3.94; p < .011), as did parent-reported school functioning of the child (median 50.00 vs. 60.00; p = .088). CONCLUSIONS: This study addressed a health disparity by culturally adapting a parenting intervention, which was designed to improve school functioning, to meet the needs and preferences of low-acculturated, Spanish-speaking families of children with leukemia in Southern California. The pilot study demonstrated that the adapted intervention is feasible and acceptable in the target population. A larger trial is underway to test the efficacy of this adapted parenting intervention.

RESUMEN

INTRODUCTION: Self-management with clinician guidance is a cornerstone of successful conservative treatment for accidental bowel leakage (ABL). There are currently few resources to assist patients with that essential self-management. The purpose of this study was to describe self-management of ABL and explore interest in a mobile health application (m-Health app) for supporting ABL self-management among community-living women. METHODS: Using an observational/descriptive design, women (18+ years) previously seen in a urogynecology clinic for ABL were mailed a survey containing eight multiple-choice questions and an open-ended prompt for comments. RESULTS: Survey responses were received from 161 women (18% response rate). The highest percentage of participants was aged 61-70 years (39%). Nearly half of the participants (47%) "did not know anything" about ABL self-management before visiting a clinician. Only 4% "knew a lot." Of those who have been trying to self-manage their ABL (n = 132), 37% reported that it was not effective, and only 5% thought their self-management was "very effective." Half (50%) of the participants had "a lot of" interest in an m-Health app to support managing ABL, and 30% had "some" interest. The vast majority (89%) thought that it was "very important" to have ongoing guidance and support for self-managing ABL. CONCLUSIONS: Before visiting a clinician, most women with ABL lacked knowledge about ABL self-management, and their self-management was not very effective. Women thought having guidance to self-manage ABL was important. There would be good interest among women in an m-Health app supporting self-management of ABL if one were created.

RESUMEN

In India, non-communicable diseases (NCDs) accounted for nearly 62% of all deaths in 2016. Four NCDs - high blood pressure, diabetes, asthma and heart disease - together accounted for over 34% of these deaths. Using data from two rounds of the India Human Development Surveys (IHDSs), levels and changes in the prevalence rates of the four NCDs (based on diagnosed cases) among adults aged 15-69 years in India between 2004-05 and 2011-12 were examined by socioeconomic and demographic factors and for five broad occupation categories. The socioeconomic and demographic risk factors for each of these NCDs were determined using multiple linear logistic regression analysis of pooled data from two rounds of the IHDS. The results showed that while urban residence, age, female sex and education were associated with higher odds of high blood pressure, diabetes and heart disease, household economic status was associated with higher odds for all four NCDs. Furthermore, increased higher odds of high blood pressure, diabetes and heart disease were found for the legislator/senior official/professional occupation group compared with non-workers. Skilled agricultural/elementary workers had lower odds of high blood pressure, diabetes, asthma and heart disease. Craft/machine-related trade workers had higher odds of high blood pressure and diabetes, and reduced odds of asthma and heart disease. Compared with non-workers, the odds ratios for asthma were lower for all other occupational categories. During the two study decades, the Government of India implemented several programmes designed to improve the health and well-being of its people. However, more focused attention on the adult population is needed, and special attention should be paid to the issue of the occupational health of the working population through the strict implementation of work place safety protocols and the removal of potential health hazards.

RESUMEN

PURPOSE: Older cancer patients are at increased risk of cancer-related cognitive impairment. The purpose of this study was to assess the alterations in intrinsic brain activity associated with adjuvant chemotherapy in older women with breast cancer. METHODS: Chemotherapy treatment (CT) group included sixteen women aged ≥ 60 years (range 60-82 years) with stage I-III breast cancers, who underwent both resting-state functional magnetic resonance imaging (rs-fMRI) and neuropsychological testing with NIH Toolbox for Cognition before adjuvant chemotherapy, at time point 1 (TP1), and again within 1 month after completing chemotherapy, at time point 2 (TP2). Fourteen age- and sex-matched healthy controls (HC) underwent the same assessments at matched intervals. Three voxel-wise rs-fMRI parameters: amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF), and regional homogeneity, were computed at each time point. The changes in rs-fMRI parameters from TP1 to TP2 for each group, the group differences in changes (the CT group vs. the HC group), and the group difference in the baseline rs-fMRI parameters were assessed. In addition, correlative analysis between the rs-fMRI parameters and neuropsychological testing scores was also performed. RESULTS: In the CT group, one brain region, which included parts of the bilateral subcallosal gyri and right anterior cingulate gyrus, displayed increased ALFF from TP1 to TP2 (cluster p-corrected = 0.024); another brain region in the left precuneus displayed decreased fALFF from TP1 to TP2 (cluster level p-corrected = 0.025). No significant changes in the rs-fMRI parameters from TP1 to TP2 were observed in the HC group. Although ALFF and fALFF alterations were observed only in the CT group, none of the between-group differences in rs-fMRI parameter changes reached statistical significance. CONCLUSIONS: Our study results of ALFF and fALFF alterations in the chemotherapy-treated women suggest that adjuvant chemotherapy may affect intrinsic brain activity in older women with breast cancer.

RESUMEN

OBJECTIVE: We examined the psychometric properties of a biopsychosocial screening tool "You, Your Family and City of Hope are a Team" implemented via touchpad technology (YYFcore03) at a cancer center in newly diagnosed patients and patients on active treatment, with the primary objective to evaluate concurrent validity with screening criterion measures of depression and anxiety. METHODS: YYFcore03, Patient Health Questionnaire [PHQ-9], and Generalized Anxiety Disorder [GAD-7] were administered to 608 patients in out-patient clinics. A subset of 158 patients responding a second time to YYFcore03 at a subsequent visit were included for assessing reliability. Exploratory factor analysis followed by confirmatory factor analysis were conducted to identify underlying factors. The identified factor of psychological distress (PD) was then correlated with PHQ-9 and GAD-7 for concurrent validity and to estimate sensitivity-specificity. Demographic and clinical variables associated with the PD score were identified. Test-retest reliability of PD score was examined. RESULTS: Factor analysis suggested three factors, including PD. Correlations between PD score and PHQ-9 and GAD-7 were 0.63 and 0.67, respectively. Treating PHQ-9 and GAD-7 as criterion measures, PD score had a sensitivity of 0.77 for identifying depression and 0.86 for identifying anxiety. Younger age, lower household income, and cancer (vs noncancer) diagnosis were independently associated with worse PD score. Omega total for composite reliability was 0.88; intraclass correlation was 0.78. CONCLUSIONS: The YYFcore03 administered via touchpad is a valid instrument for identifying PD in newly diagnosed patients and patients undergoing active treatment.
