RESUMEN

OBJECTIVE: The aim of this study was to evaluate the prognostic impact of concomitant prostate cancer (PCa) of the cancer-specific mortality (CSM) in the aging patient's papulation with bladder cancer (BCa) treated with radical cystoprostatectomy (RCP). MATERIALS AND METHODS: Within the SEER database (2004-2015), 1468 patients were treated with RCP for BCa harboring histopathological PCa findings. To account for other cause mortality (OCM), multivariable competing risk regression (CRR) tested for potential BCa-CSM differences according to PCa characteristics risk factors predicting CSM. RESULTS: CRR analysis revealed that only following BCa characteristics, as high pathological tumor stages(Ta/Tis/T1 [REF.] vs. T2; HR 2.03, 95% CI: 1.16-3.57, p = 0.014 vs. T3; HR 4.32, 95% CI: 2.45-7.61, p < 0.001 vs. T4; HR 5.06, 95% CI: 2.77-9.22, p < 0.001), as well unfavorable BCa grade IV (Grade I-II [REF.] vs. Grade IV; HR 0.58, 95% CI: 0.35-0.98, p < 0.041) achieved independent predictor status of CSM. With regard to PCa characteristics, none of the covariates yielded independent predictor status of CSM. CONCLUSIONS: Our study, based on the largest population cohort, demonstrates that even in organ-confined BCa patients, concomitant PCa as second malignancy does not represent a risk factor for survival.

RESUMEN

Older adults are often overlooked in decision making processes despite the detrimental effects on their well-being. The representation of older adults in investigations and initiatives is needed so that the issues they face, today and in the future, can be resolved through partnership and their active involvement. The aim of this article is to describe a participatory process for conducting a needs assessment (NA) and the contributions and opportunities of partnering with older adults to shape community services and support for older adults. Data were collected from 1,863 participants in a midwestern county via focus groups, interviews, and surveys. We describe how participatory principles were enacted, the involvement of older adults influenced the design and contributed to making sure hard-to-reach residents' voices were included. Finally, we discuss the ways in which a community inclusive multi-method strategy can optimize resource allocation, identify pathways to more effective policymaking that is matched to the needs and interests of its oldest residents, and lead to unanticipated benefits. Single method, non-inclusive approaches can obscure the critical context and exclude perspectives of the most burdened and vulnerable, who are most in need of support from their community.

RESUMEN

When species spread into new regions, competition with native species and predatory-prey relationships play a major role in whether the new species can successfully establish itself in the recipient food web and become invasive. In aquatic habitats, species with a metagenetic life cycle, such as the freshwater jellyfish Craspedacusta with benthic polyps and planktonic medusae, have to meet the requirements of two distinct life stages occurring in two habitats with different food webs. Here, we examined the trophic position of both life stages, known to be predatory, and compared their niches with those of putative native competitors using stable isotope analysis. We found that δ13C and δ15N signatures of medusae overlapped with those of co-occurring Chaoborus larvae and juvenile fish (Rutilus rutilus) in a well-studied lake, implying high competition with these native predators. The comparison of δ15N signatures of Hydra and Craspedacusta polyps in four additional lakes revealed their similar trophic position, matching their predatory lifestyle. However, their δ13C signatures differed not only across all four of the lakes studied but also within one lake over time, suggesting a preference for pelagic or benthic food sources. We conclude that invasive and native polyps differ in their niches due to different food spectra, which favors the invasion success of Craspedacusta.

RESUMEN

The overenrichment (eutrophication) of aquatic ecosystems with nutrients leading to algal blooms and anoxic conditions has been a persistent and widespread environmental problem. Although there are many studies on the ecological impact of elevated phosphorus (P) levels (e.g., decrease in biodiversity and water quality), little is known about the evolutionary consequences for animal species. We reconstructed the genetic architecture of a Daphnia species complex in 2 European lakes using diapausing eggs that were isolated from sediment layers covering the past 100 years. Changes in total P were clearly associated with a shift in species composition and the population structure of evolutionary lineages. Although environmental conditions were largely re-established after peak eutrophication during the 1970s and 1980s, original species composition and the genetic architecture of species were not restored but evolved along new evolutionary trajectories. Our data demonstrate that anthropogenically induced temporal alterations of habitats are associated with long-lasting changes in communities and species via interspecific hybridization and introgression.

RESUMEN

The quality of life (QoL) of men with optimal outcomes after robot-assisted radical prostatectomy (RARP) is largely unexplored. Thus we assessed meaningful changes of QoL measured with the EORTC QLQ-C30 24 months after RARP according to postsurgical Cancer of the Prostate Risk Assessment score (CAPRA-S) and pentafecta criteria. 2871 prostate cancer (PCa) patients with completed EORTC QLQ-C30 were stratified according to CAPRA-S, pentafecta (erectile function recovery, urinary continence recovery, biochemical-recurrence-free survival (BFS), negative surgical margins) and 90-day Clavien-Dindo-complications (CDC) ≤ 3a. Multivariable logistic regression analyses (LRM) aimed to predict improvement of EORTC QoL. Mean preoperative QoL values did not significantly differ between CAPRA-S low- (LR) vs. high-risk (HR, 75.7 vs. 75.2; p = 0.7) and pentafecta vs. non-pentafecta groups (75.6 vs. 75.2; p = 0.6). After RARP, stable QoL rates for CAPRA-S LR vs. HR and pentafecta were 30, 26 and 30%, respectively. Corresponding improved QoL rates were 44, 32 and 47%. In LRM, CAPRA-S and pentafecta criteria were independent predictors of improved QoL. We conclude that most favourable combined outcomes after RARP might confer stable or even improved QoL but up to one third of patients might experience deterioration. This warrants further investigation how to capture the underlying cause and to address and potentially solve these perceived negative effects despite successful RARP.

RESUMEN

The Short-Form Health Survey (SF-12; Ware, Kosinski, & Keller, 1996) is a widely used screening device for measuring physical and mental health to assess quality of life. However, limited psychometric data exist for older adults, especially minority aging samples. Findings from Resnick and Nahm (2001) suggest revising traditional SF-12 scoring for use in older adults because of different factor loadings for two questions. This study sought to examine the reliability and validity of a verbally administered SF-12 in a community-dwelling sample of African Americans using the Detroit City-Wide Needs Assessment Database (N = 985). Reliability analysis resulted in an overall Cronbach's alpha of 0.77. Factor analysis with principal components extraction and varimax rotation yielded two factors. Consistent with Resnick and Nahm (2001), question 10 loaded on the physical health factor and question 12 on both the physical and the mental health factors. The overall SF-12 score was significantly related to use of home health services, visits to a physician, number of prescription drugs, as well as number of chronic diseases. The SF-12 appears to be a valid and reliable measure used as a screening device for use with African American elders overall. However, for optimal measurement, modifications to traditional scoring methods for the SF-12 should be considered.

RESUMEN

A newly compiled data set of nearly complete sequences of the large subunit of the nuclear ribosome (LSU or 28S) sampled from 31 diverse medusozoans greatly clarifies the phylogenetic history of Cnidaria. These data have substantial power to discern among many of the competing hypotheses of relationship derived from prior work. Moreover, LSU data provide strong support at key nodes that were equivocal based on other molecular markers. Combining LSU sequences with those of the small subunit of the nuclear ribosome (SSU or 18S), we present a detailed working hypothesis of medusozoan relationships and discuss character evolution within this diverse clade. Stauromedusae, comprising the benthic, so-called stalked jellyfish, appears to be the sister group of all other medusozoans, implying that the free-swimming medusa stage, the motor nerve net, and statocysts of ecto-endodermal origin are features derived within Medusozoa. Cubozoans, which have had uncertain phylogenetic affinities since the elucidation of their life cycles, form a clade-named Acraspeda-with the scyphozoan groups Coronatae, Rhizostomeae, and Semaeostomeae. The polyps of both cubozoans and hydrozoans appear to be secondarily simplified. Hydrozoa is comprised by two well-supported clades, Trachylina and Hydroidolina. The position of Limnomedusae within Trachylina indicates that the ancestral hydrozoan had a biphasic life cycle and that the medusa was formed via an entocodon. Recently hypothesized homologies between the entocodon and bilaterian mesoderm are therefore suspect. Laingiomedusae, which has often been viewed as a close ally of the trachyline group Narcomedusae, is instead shown to be unambiguously a member of Hydroidolina. The important model organisms of the Hydra species complex are part of a clade, Aplanulata, with other hydrozoans possessing direct development not involving a ciliated planula stage. Finally, applying phylogenetic mixture models to our data proved to be of little additional value over a more traditional phylogenetic approach involving explicit hypothesis testing and bootstrap analyses under multiple optimality criteria.
