    Shorter survival has been associated with low socioeconomic status (SES) among elderly non-Hodgkin's lymphoma (NHL) patients; however it remains unknown whether the same relationship holds for younger patients. We explored the California Cancer Registry (CCR), to investigate this relationship in adolescent and young adult (AYA) NHL patients diagnosed from 1996 to 2005. A case-only survival analysis was conducted to examine demographic and clinical variables hypothesized to be related to survival. Included in the final analysis were 3,489 incident NHL cases. In the multivariate analyses, all-cause mortality (ACM) was higher in individuals who had later stage at diagnosis (P < .05) or did not receive first-course chemotherapy (P < .05). There was also a significant gradient decrease in survival, with higher ACM at each decreasing quintile of SES (P < .001). Overall results were similar for lymphoma-specific mortality. In the race/ethnicity stratified analyses, only non-Hispanic Whites (NHWs) had a significant SES-ACM trend (P < .001). Reduced overall and lymphoma-specific survival was associated with lower SES in AYAs with NHL, although a significant trend was only observed for NHWs

    Background Many informal caregivers experience significant caregiving burden and report worsening health-related quality of life (HRQoL). Caregiver HRQoL may vary by disease context, but this has rarely been studied. Purpose Informed by the Model of Carer Stress and Burden, we compared HRQoL outcomes of prevalent groups of caregivers of people with chronic illness (i.e., dementia, cancer, chronic obstructive pulmonary disease [COPD]/emphysema, and diabetes) and noncaregivers and examined whether caregiving intensity (e.g., duration and hours) was associated with caregiver HRQoL. Methods Using 2015–2018 Behavioral Risk Factor Surveillance System data, we identified caregivers of people with dementia (n = 4,513), cancer (n = 3,701), COPD/emphysema (n = 1,718), and diabetes (n = 2,504) and noncaregivers (n = 176,749). Regression analyses were used to compare groups. Results Caregiver groups showed small, nonsignificant differences in HRQoL outcomes. Consistent with theory, all caregiver groups reported more mentally unhealthy days than noncaregivers (RRs = 1.29–1.61, ps < .001). Caregivers of people with cancer and COPD/emphysema reported more physically unhealthy days than noncaregivers (RRs = 1.17–1.24, ps < .01), and caregivers of people with diabetes reported a similar pattern (RR = 1.24, p = .01). However, general health and days of interference of poor health did not differ between caregivers and noncaregivers. Across caregiver groups, most caregiving intensity variables were unrelated to HRQoL outcomes; only greater caregiving hours were associated with more mentally unhealthy days (RR = 1.13, p < .001). Conclusions Results suggest that HRQoL decrements associated with caregiving do not vary substantially across chronic illness contexts and are largely unrelated to the perceived intensity of the caregiving. Findings support the development and implementation of strategies to optimize caregiver health across illness contexts

    Patient experiences of cancer care: scoping review, future directions, and introduction of a new data resource: Surveillance Epidemiology and End Results-Consumer Assessment of Healthcare Providers and Systems (SEER-CAHPS)

    The shift towards providing high value cancer care has placed increasing importance on patient experiences. This scoping review summarizes patient experience literature, highlights research gaps, and provides future research directions. We then introduce a new resource that links the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) program with the Centers for Medicare and Medicaid Services Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey and longitudinal medical claims data. We conducted a scoping review to identify relevant research within the Medicare CAHPS domain that examine factors associated with patient-reported experiences with their cancer care. Gaps indicate a need for population-based research to explore relationships between cancer patient experiences, healthcare utilization, and subsequent patient outcomes. SEER-CAHPS, a publicly accessible data resource, may assist in addressing these gaps by linking cancer registry (SEER), survey data reported by Medicare beneficiaries (CAHPS), and Medicare claims, providing unique insight into quality of care. Linked data include 231,089 surveys from patients with a cancer diagnosis, and 4,236,529 surveys from patients without a cancer diagnosis. Results indicate substantial gaps in our knowledge of patient experiences and the need for additional resources. SEER-CAHPS links direct patient feedback with cancer registry and Medicare claims, making it an important source of information on experiences and healthcare utilization. Increasing recognition of the importance of patient-centeredness points to the need for population-based studies. Findings from SEER-CAHPS will inform initiatives to improve care delivery

    INTRODUCTION: Many informal caregivers experience a significant caregiving burden, which may interfere with their health behaviors. Caregiver health behaviors may vary by disease context, but this has rarely been studied. This study compares the health behaviors of prevalent groups of chronic illness caregivers (i.e., dementia, cancer, chronic obstructive pulmonary disease/emphysema, diabetes) with those of noncaregivers and examines whether caregiving intensity is associated with these behaviors. METHODS: In 2021, using pooled cross-sectional 2015-2019 Behavioral Risk Factor Surveillance System data, health behaviors (i.e., physical activity, diet, alcohol use, smoking, sleep, and influenza immunization) of caregivers of patients with dementia (n=5,525), cancer (n=4,246), chronic obstructive pulmonary disease/emphysema (n=1,959), and diabetes (n=2,853) and noncaregivers (n=203,848) were compared. Relationships between caregiving intensity (e.g., hours, type of tasks) and caregiver health behaviors were examined. Regression analyses were used to compare groups. RESULTS: Compared with noncaregivers, caregiver groups were more likely to report engaging in both risky (i.e., smoking, shorter sleep duration) and health-promoting (i.e., physical activity, vegetable consumption, abstaining from heavy drinking) behaviors, whereas nonsignificant differences were observed for influenza immunization. Longer caregiving hours and providing help with personal care were associated with poorer health behaviors (e.g., shorter sleep duration). Few differences in health behaviors were observed between caregivers of patients with dementia and other caregiver groups. CONCLUSIONS: Results suggest that caregivers are more likely to engage in both risky and health-promoting behaviors than noncaregivers. Furthermore, findings suggest that greater caregiving responsibilities are associated with certain risky health behaviors. Findings support the development and implementation of strategies to improve caregivers' health behaviors across disease contexts

    Abstract Serum samples from all twenty-three known living members of the Crocodylia were tested for antibacterial activity against eight bacterial species. These data were used to generate an immune profile for each crocodylian species. Statistical analyses revealed that the three living lineages of crocodylians, Alligatoroidea, Crocodyloidea, and Gavialoidea, were distinguishable by their immunological activities. For instance, species within the Alligatoroidea and Crocodyloidea exhibited remarkable immune activity similarities to others in their own lineages. Comparisons of the members of the different lineages, however, revealed substantial differences in immune profiles. Furthermore, species that are in the same genus were shown to exhibit more immune similarities to each other than to members of other genera within the same family. Finally, our immunological analyses reveal that Tomistoma schlegelii aligns more closely with the Gavialoidea than the Crocodyloidea.

    Financial Burden and Mental Health Among LGBTQIA+ Adolescent and Young Adult Cancer Survivors During the COVID-19 Pandemic

    Background In the United States, the cost of cancer treatment can lead to severe financial burden for cancer survivors. The economic impacts of the COVID-19 pandemic compound cancer survivors’ financial challenges. Financial burden may be particularly challenging for lesbian, gay, bisexual, transgender, queer, intersex, asexual and other sexual and gender minority (LGBTQIA+) survivors. LGBTQIA+ survivors who are adolescent and young adults (AYA) may face elevated financial burden due to multiple, intersecting identities. Methods An explanatory sequential mixed methods design was applied, beginning with a survey of AYA cancer survivors in the Mountain West region of the United States. Survey measures included demographics, COVID-19 impacts, the COmprehensive Score for financial Toxicity (COST), Perceived Stress Scale-4 (PSS-4), and PROMIS anxiety and depression scales. Two-way t-tests were used to analyze differences in outcomes between LGBTQIA+ and non-LGBTQIA+ AYAs. All LGBTQIA+ survey participants were invited to complete an interview, and those who agreed participated in descriptive interviews about financial burden due to cancer, COVID-19, and LGBTQIA+ identity. Interviews were audio recorded, transcribed, and analyzed using Dedoose. Results Survey participants (N=325) were LGBTQIA+ (n=29, 8.9%), primarily female (n= 197, 60.6%), non-Hispanic White (n= 267, 82.2%), and received treatment during COVID-19 (n= 174, 54.0%). LGBTQIA+ interview participants (n=9, 100%) identified as a sexual minority and (n=2, 22.2%) identified as a gender minority. Most were non-Hispanic White (n=6, 66.7%) and had received treatment during COVID-19 (n=7, 77.8%). Statistical analyses revealed that LGBTQIA+ AYAs reported significantly worse COST scores than non-LGBTQIA+ AYAs (p=0.002). LGBTQIA+ AYAs also reported significantly higher PSS-4 (p=0.001), PROMIS anxiety (p=0.002) and depression scores (p<0.001) than non-LGBTQIA+ AYAs, reflecting worse mental health outcomes. High costs of cancer treatment and employment disruptions due to COVID-19 contributed to substantial financial stress, which exacerbated existing mental health challenges and introduced new ones. Conclusions LGBTQIA+ AYA survivors reported substantial financial burden and psychological distress exacerbated by cancer, the COVID-19 pandemic, and LGBTQIA+ stigma. Given their multiple intersecting identities and potential for marginalization, LGBTQIA+ AYA survivors deserve prioritization in research to reduce financial burden and poor mental health

    ObjectiveThis cohort study examined the impact of cancer on sexual function and intimate relationships in adolescents and young adults (AYAs). We also explored factors predicting an increased likelihood that cancer had negatively affected these outcomes.MethodsParticipants (nâ =â 465, ages 15â 39) in the Adolescent and Young Adult Health Outcomes and Patient Experience (AYA HOPE) study completed two surveys approximately 1 and 2 years postâ cancer diagnosis. We used multivariable logistic regression to determine factors negatively affected by perceptions of sexual function at 2 years postâ diagnosis.ResultsFortyâ nine percent of AYAs reported negative effects on sexual function at 1 year postâ cancer diagnosis and 70% of those persisted in their negative perceptions 2 years after diagnosis. Those reporting a negative impact at 2 years were more likely to be 25 years or older (OR, 2.53; 95% CI, 1.44â 4.42), currently not raising children (OR, 1.81; 95% CI, 1.06â 3.08), experiencing fatigue (OR, 0.99; 95% CI, 0.975â 0.998) and more likely to report that their diagnosis has had a negative effect on physical appearance (OR, 3.08; 95% CI, 1.97â 4.81). Clinical factors and mental health were not significant predictors of negative effects on sexual function.ConclusionsMany AYAs diagnosed with cancer experience a persistent negative impact on sexual life up to 2 years following diagnosis. The findings underscore the need to develop routine protocols to assess sexual function in AYAs with cancer and to provide comprehensive management in the clinical setting.

    CG dinucleotide clustering is a species-specific property of the genome

    Get PDF
    Cytosines at cytosine-guanine (CG) dinucleotides are the near-exclusive target of DNA methyltransferases in mammalian genomes. Spontaneous deamination of methylcytosine to thymine makes methylated cytosines unusually susceptible to mutation and consequent depletion. The loci where CG dinucleotides remain relatively enriched, presumably due to their unmethylated status during the germ cell cycle, have been referred to as CpG islands. Currently, CpG islands are solely defined by base compositional criteria, allowing annotation of any sequenced genome. Using a novel bioinformatic approach, we show that CG clusters can be identified as an inherent property of genomic sequence without imposing a base compositional a priori assumption. We also show that the CG clusters co-localize in the human genome with hypomethylated loci and annotated transcription start sites to a greater extent than annotations produced by prior CpG island definitions. Moreover, this new approach allows CG clusters to be identified in a species-specific manner, revealing a degree of orthologous conservation that is not revealed by current base compositional approaches. Finally, our approach is able to identify methylating genomes (such as Takifugu rubripes) that lack CG clustering entirely, in which it is inappropriate to annotate CpG islands or CG clusters

    Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112

    Full text link
    We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62''. The system has been confirmed as a lensed quasar at z=1.734 on the basis of deep imaging and spectroscopic follow-up observations. We present color-magnitude relations for galaxies near the lens plus spectroscopy of three central cluster members, which unambiguously confirm that a cluster at z=0.68 is responsible for the large image separation. We find a wide range of lens models consistent with the data, but they suggest four general conclusions: (1) the brightest cluster galaxy and the center of the cluster potential well appear to be offset by several kpc; (2) the cluster mass distribution must be elongated in the North--South direction, which is consistent with the observed distribution of cluster galaxies; (3) the inference of a large tidal shear (~0.2) suggests significant substructure in the cluster; and (4) enormous uncertainty in the predicted time delays between the images means that measuring the delays would greatly improve constraints on the models. We also compute the probability of such large separation lensing in the SDSS quasar sample, on the basis of the CDM model. The lack of large separation lenses in previous surveys and the discovery of one in SDSS together imply a mass fluctuation normalization \sigma_8=1.0^{+0.4}_{-0.2} (95% CL), if cluster dark matter halos have an inner slope -1.5. Shallower profiles would require higher values of \sigma_8. Although the statistical conclusion might be somewhat dependent on the degree of the complexity of the lens potential, the discovery is consistent with the predictions of the abundance of cluster-scale halos in the CDM scenario.
