Young adults with chronic kidney disease: an exploration of their relationships and support networks

Background: Young people with chronic kidney disease (CKD) have a number of key issues and life changes to manage while also possibly transitioning into adult care. During this time, the nature of their support networks including, social, romantic, family and health care relationships, is changing.Objective: To explore these young people's experience and perceptions of their past, current and future relationships and support networks.Design: Qualitative study.Participants and Methods : Fourteen young adults (8 male, 6 female, aged 18–26 years) with CKD Stages 3–5 participated. Semi‐structured interviews were conducted in order to explore the relationships (friends, family and partners) of young adults with CKD at two UK NHS hospitals. These were transcribed and thematically analysed.Results: There were four themes identified. ‘Disclosure—To tell or not to tell?’ identified the challenges young adults face when disclosing their condition to friends and prospective partners. ‘Managing support networks’ showed that participants appreciated support from other young adults with CKD but also desired just ‘being normal’ with their friends. While family support is still significant and much appreciated, some young adults also found it harder to develop their independence. ‘Relationship strains and carer needs’ highlights the impact of CKD on all relationships. Participants were also aware of the needs of their ‘carers’. In ‘Happy ever after?’ young adults expressed concerns about meeting a partner and having children.Conclusions: Young adults with CKD need support in helping them manage new and existing relationships, at a time where relationships are taking on different forms and significance. Moreover, support needs for young adults extend beyond the patient, to those who support them; support services need to reflect this

Developing an in-depth understanding of patient and caregiver engagement across care transitions from hospital: protocol for a qualitative study exploring experiences in Canada

INTRODUCTION: Patient and caregiver engagement is critical, and often compromised, at points of transition between care settings, which are more common, and more challenging, for patients with complex medical problems. The consequences of poor care transitions are well-documented, both for patients and caregivers, and for the healthcare system. With an ageing population, there is greater need to focus on care transition experiences of older adults, who are often more medically complex, and more likely to require care from multiple providers across settings. The overall goal of this study is to understand what factors facilitate or hinder patient and caregiver engagement through transitions in care, and how these current engagement practices align with a previously developed engagement framework (CHOICE Framework). This study also aims to co-develop resources needed to support engagement and identify how these resources and materials should be implemented in practice. METHODS AND ANALYSIS: This study uses ethnographic approaches to explore the dynamics of patient and caregiver engagement, or lack thereof, during care transitions across three regions within Ontario. With the help of a front-line champion, patients (n=18-24), caregivers (n=18-24) and healthcare providers (n=36-54) are recruited from an acute care hospital unit (or similar) and followed through their care journey. Data are collected using in-depth semi-structured interviews. Workshops will be held to co-develop strategies and a plan for future implementation of resources and materials. Analysis of the data will use inductive and deductive coding techniques. ETHICS AND DISSEMINATION: Ethics clearance was obtained through the Western University Research Ethics Board, University of Windsor Research Ethics Board and the University of Waterloo Office of Research Ethics. The findings from this study are intended to contribute valuable evidence to further bridge the knowledge to practice gap in patient and caregiver engagement through care transitions. Findings will be disseminated through publications, conference presentations and reports

Evolution of Symbiotic Bacteria in the Distal Human Intestine

The adult human intestine contains trillions of bacteria, representing hundreds of species and thousands of subspecies. Little is known about the selective pressures that have shaped and are shaping this community's component species, which are dominated by members of the Bacteroidetes and Firmicutes divisions. To examine how the intestinal environment affects microbial genome evolution, we have sequenced the genomes of two members of the normal distal human gut microbiota, Bacteroides vulgatus and Bacteroides distasonis, and by comparison with the few other sequenced gut and non-gut Bacteroidetes, analyzed their niche and habitat adaptations. The results show that lateral gene transfer, mobile elements, and gene amplification have played important roles in affecting the ability of gut-dwelling Bacteroidetes to vary their cell surface, sense their environment, and harvest nutrient resources present in the distal intestine. Our findings show that these processes have been a driving force in the adaptation of Bacteroidetes to the distal gut environment, and emphasize the importance of considering the evolution of humans from an additional perspective, namely the evolution of our microbiomes

Kinetoplastid Phylogenomics Reveals the Evolutionary Innovations Associated with the Origins of Parasitism

The evolution of parasitism is a recurrent event in the history of life and a core problem in evolutionary biology. Trypanosomatids are important parasites and include the human pathogens Trypanosoma brucei, Trypanosoma cruzi, and Leishmania spp., which in humans cause African trypanosomiasis, Chagas disease, and leishmaniasis, respectively. Genome comparison between trypanosomatids reveals that these parasites have evolved specialized cell-surface protein families, overlaid on a well-conserved cell template. Understanding how these features evolved and which ones are specifically associated with parasitism requires comparison with related non-parasites. We have produced genome sequences for Bodo saltans, the closest known non-parasitic relative of trypanosomatids, and a second bodonid, Trypanoplasma borreli. Here we show how genomic reduction and innovation contributed to the character of trypanosomatid genomes. We show that gene loss has “streamlined” trypanosomatid genomes, particularly with respect to macromolecular degradation and ion transport, but consistent with a widespread loss of functional redundancy, while adaptive radiations of gene families involved in membrane function provide the principal innovations in trypanosomatid evolution. Gene gain and loss continued during trypanosomatid diversification, resulting in the asymmetric assortment of ancestral characters such as peptidases between Trypanosoma and Leishmania, genomic differences that were subsequently amplified by lineage-specific innovations after divergence. Finally, we show how species-specific, cell-surface gene families (DGF-1 and PSA) with no apparent structural similarity are independent derivations of a common ancestral form, which we call “bodonin.” This new evidence defines the parasitic innovations of trypanosomatid genomes, revealing how a free-living phagotroph became adapted to exploiting hostile host environments

Changes to the law on consent in South Africa: implications for school-based adolescent sexual and reproductive health research

BACKGROUND:The National Health Act, No 61, 2003 in South Africa is the first effort made by the government to protect health-related research participants under law. Implemented on March 1, 2012, the law mandates active consent from a parent or legal guardian for all research conducted with research participants under the age of 18 years. This paper focuses on the Act's implications for school-based adolescent sexual and reproductive health research.DISCUSSION:Although well intentioned, the added legal protections in the National Health Act may have the unintended consequence of reducing participation rates in school-based adolescent sexual and reproductive health research, thereby excluding the most at-risk students. The Act may also compromise adolescents' right to dignity and privacy, especially considering the personal nature of research on sex and sexuality. Devolved, discretionary decision-making, which empowers local human research ethics committees to permit a wider range of protective measures, including passive consent, independent adolescent consent or community consultation ought to be considered. The continued and direct involvement of young people in their sexual and reproductive health and well-being is an important principle to uphold.SUMMARY:This paper calls for a re-examination of section 71's ethical guidelines relating to informed consent in the National Health Act, No 61, 2003 in South Africa in order to better serve the interests of South African adolescents in sexual and reproductive health research

Do people with risky behaviours participate in biomedical cohort studies?

BACKGROUND: Analysis was undertaken on data from randomly selected participants of a bio-medical cohort study to assess representativeness. The research hypotheses was that there was no difference in participation and non-participations in terms of health-related indicators (smoking, alcohol use, body mass index, physical activity, blood pressure and cholesterol readings and overall health status) and selected socio-demographics (age, sex, area of residence, education level, marital status and work status). METHODS: Randomly selected adults were recruited into a bio-medical representative cohort study based in the north western suburbs of the capital of South Australia – Adealide. Comparison data was obtained from cross-sectional surveys of randomly selected adults in the same age range and in the same region. The cohort participants were 4060 randomly selected adults (18+ years). RESULTS: There were no major differences between study participants and the comparison population in terms of current smoking status, body mass index, physical activity, overall health status and proportions with current high blood pressure and cholesterol readings. Significantly more people who reported a medium to very high alcohol risk participated in the study. There were some demographic differences with study participants more likely to be in the middle level of household income and education level. CONCLUSION: People with risky behaviours participated in this health study in the same proportions as people without these risk factors

Evidence for Induction of Integron-Based Antibiotic Resistance by the SOS Response in a Clinical Setting

Bacterial resistance to β-lactams may rely on acquired β-lactamases encoded by class 1 integron-borne genes. Rearrangement of integron cassette arrays is mediated by the integrase IntI1. It has been previously established that integrase expression can be activated by the SOS response in vitro, leading to speculation that this is an important clinical mechanism of acquiring resistance. Here we report the first in vivo evidence of the impact of SOS response activated by the antibiotic treatment given to a patient and its output in terms of resistance development. We identified a new mechanism of modulation of antibiotic resistance in integrons, based on the insertion of a genetic element, the gcuF1 cassette, upstream of the integron-borne cassette blaOXA-28 encoding an extended spectrum β-lactamase. This insertion creates the fused protein GCUF1-OXA-28 and modulates the transcription, the translation, and the secretion of the β-lactamase in a Pseudomonas aeruginosa isolate (S-Pae) susceptible to the third generation cephalosporin ceftazidime. We found that the metronidazole, not an anti-pseudomonal antibiotic given to the first patient infected with S-Pae, triggered the SOS response that subsequently activated the integrase IntI1 expression. This resulted in the rearrangement of the integron gene cassette array, through excision of the gcuF1 cassette, and the full expression the β-lactamase in an isolate (R-Pae) highly resistant to ceftazidime, which further spread to other patients within our hospital. Our results demonstrate that in human hosts, the antibiotic-induced SOS response in pathogens could play a pivotal role in adaptation process of the bacteria
