De novo assembly and annotation of the Patagonian toothfish (Dissostichus eleginoides) genome.

BACKGROUND: Patagonian toothfish (Dissostichus eleginoides) is an economically and ecologically important fish species in the family Nototheniidae. Juveniles occupy progressively deeper waters as they mature and grow, and adults have been caught as deep as 2500 m, living on or in just above the southern shelves and slopes around the sub-Antarctic islands of the Southern Ocean. As apex predators, they are a key part of the food web, feeding on a variety of prey, including krill, squid, and other fish. Despite its importance, genomic sequence data, which could be used for more accurate dating of the divergence between Patagonian and Antarctic toothfish, or establish whether it shares adaptations to temperature with fish living in more polar or equatorial climes, has so far been limited. RESULTS: A high-quality D. eleginoides genome was generated using a combination of Illumina, PacBio and Omni-C sequencing technologies. To aid the genome annotation, the transcriptome derived from a variety of toothfish tissues was also generated using both short and long read sequencing methods. The final genome assembly was 797.8 Mb with a N50 scaffold length of 3.5 Mb. Approximately 31.7% of the genome consisted of repetitive elements. A total of 35,543 putative protein-coding regions were identified, of which 50% have been functionally annotated. Transcriptomics analysis showed that approximately 64% of the predicted genes (22,617 genes) were found to be expressed in the tissues sampled. Comparative genomics analysis revealed that the anti-freeze glycoprotein (AFGP) locus of D. eleginoides does not contain any AFGP proteins compared to the same locus in the Antarctic toothfish (Dissostichus mawsoni). This is in agreement with previously published results looking at hybridization signals and confirms that Patagonian toothfish do not possess AFGP coding sequences in their genome. CONCLUSIONS: We have assembled and annotated the Patagonian toothfish genome, which will provide a valuable genetic resource for ecological and evolutionary studies on this and other closely related species.

'Localism and intimacy, and other rather imponderable reasons of that sort': A qualitative study of patient experience of community hospitals in England.

Debates over the value and contribution of community hospitals are hampered by a lack of empirical assessment of the experience of patients using these services. This paper presents findings from a study which included a focus on patient and family-carer experiences of community hospitals in England. We adopted a qualitative design involving nine case study hospitals. Data collection included interviews with patients (n = 60), carers (n = 28) and staff (n = 89). Through patients and carers highlighting the value of community hospitals feeling 'close to home', providing holistic and personalised care and supporting them through difficult transitions, the study confirms the importance of functional and interpersonal aspects of care, while also highlighting the importance of social and psychological aspects. These included having family, friends and the community close, maintaining social connections during periods of hospital treatment, and feeling less anonymous and anxious when attending the hospital due to the high levels of familiarity and connectedness. Although the experiences uncovered in this study were not uniformly positive, patients and carers placed a high overall value on the care provided by community hospitals, often arguing that these were distinctive when compared to their experiences of using other health and care services. The study suggests the need to weigh the full range of these dimensions of patient experience-functional, interpersonal, social and psychological-when assessing the role and contribution of community hospitals.

Memorial tattoos: Advancing continuing bonds theory.

A memorial tattoo is a tattoo that honors a person who has died. We aimed to understand how memorial tattoos could be an expression of a bereaved person's continuing relationship with the deceased person that the tattoo memorializes. We interviewed 41 people and used qualitative description grounded in a symbolic interactionist framework to analyze the transcripts. This research expands on continuing bonds theory by showing that memorial tattoos are an expression of the bond with the deceased as well as a way to communicate with others about their ongoing connection and to challenge stigma.

Patient compliance with hip precautions 12 weeks following primary elective total hip arthroplasty.

INTRODUCTION: Patients are routinely advised to follow hip precautions following their total hip arthroplasty (THA) surgery. There is lack of evidence regarding compliance with these precautions and when patients return to activities of daily living following their surgery. MATERIALS AND METHODS: We designed a new questionnaire to discover when patients return to their activities of daily living. Two hundred and ninety seven consecutive patients who attended 12 week follow up arthroplasty clinic following their primary elective THA were asked to complete the questionnaire. RESULTS: All patients who attended the follow up clinic at 12 weeks responded to the questionnaire. Only 6.3% (n = 19) of the patients reported that they restricted their daily activities, as prescribed for the full 12 week period, while 50% (n = 148) of patients stopped using prescribed adaptive equipment by 6 weeks after their operation. There were no dislocations recorded among the study group. CONCLUSION: We found that the majority of patients do not adhere to hip precautions advice. They return to their activities of daily living prior to the end of prescription period based on their pain and activity level. Lack of adherence to hip precautions do not predispose to hip dislocation in the immediate post-operative period.

Communities as 'renewable energy' for healthcare services? a multimethods study into the form, scale and role of voluntary support for community hospitals in England.

OBJECTIVE: To examine the forms, scale and role of community and voluntary support for community hospitals in England. DESIGN: A multimethods study. Quantitative analysis of Charity Commission data on levels of volunteering and voluntary income for charities supporting community hospitals. Nine qualitative case studies of community hospitals and their surrounding communities, including interviews and focus groups. SETTING: Community hospitals in England and their surrounding communities. PARTICIPANTS: Charity Commission data for 245 community hospital Leagues of Friends. Interviews with staff (89), patients (60), carers (28), volunteers (35), community representatives (20), managers and commissioners (9). Focus groups with multidisciplinary teams (8 groups across nine sites, involving 43 respondents), volunteers (6 groups, 33 respondents) and community stakeholders (8 groups, 54 respondents). RESULTS: Communities support community hospitals through: human resources (average=24 volunteers a year per hospital); financial resources (median voluntary income = £15 632); practical resources through services and activities provided by voluntary and community groups; and intellectual resources (eg, consultation and coproduction). Communities provide valuable supplementary resources to the National Health Service, enhancing community hospital services, patient experience, staff morale and volunteer well-being. Such resources, however, vary in level and form from hospital to hospital and over time: voluntary income is on the decline, as is membership of League of Friends, and it can be hard to recruit regular, active volunteers. CONCLUSIONS: Communities can be a significant resource for healthcare services, in ways which can enhance patient experience and service quality. Harnessing that resource, however, is not straight forward and there is a perception that it might be becoming more difficult questioning the extent to which it can be considered sustainable or 'renewable'.

Factors affecting the changing role of GP clinicians in community hospitals: a qualitative interview study in England.

BACKGROUND: GPs were a key driving force for the development of a network of community hospitals across England, and have provided medical cover for most of them. However, during the past decade there has been a significant shift, with the dominant trend appearing to be one of declining GP involvement. AIM: To explore how and why the role of GPs within community hospitals in England is changing. DESIGN AND SETTING: Qualitative study in a sample of nine diverse community hospitals in England. METHOD: Qualitative interviews with community hospital clinical staff. RESULTS: In all, 20 interviews were conducted and two models of medical care observed: GPs employed by a practice and trust-employed doctors. Interviewees confirmed the trend towards declining GP involvement, with the factors driving change identified as being GP workload and recruitment challenges, a change from 'step-up' admissions from the community to 'step-down' admissions from acute hospitals, fewer local patients being admitted, increased medical acuity of patients admitted, increased burden of medical support required, and inadequate remuneration. The majority of doctors viewed community hospital work in a positive light, welcoming the opportunities for personal development and to acquire new clinical skills. GPs viewed community hospital work as an extension of primary care, adding to job satisfaction. CONCLUSION: Multiple factors have driven changes in the role of GP community hospital clinicians. The NHS needs to develop a focused strategy if GPs are to remain engaged with community hospital work.

Strategies to Promote the Inclusion of Young Adults With Developmental Disabilities in Community-Based Health Studies.

We discuss strategies to promote the inclusion of people with developmental disabilities (DDs) in qualitative community-based research studies. Strategies were applied in three projects conducted between 2012 and 2017 that addressed issues of socioeconomic challenges, discrimination, and exclusion of children and young adults with developmental disabilities (YADD). Strategies included partnership with community organizations; inclusion of YADD, family caregivers (FCs), and service providers in advisory committees (ACs); and strategies to accommodate YADD. As part of our contribution, we discuss issues of invisibility and exclusion of individuals with DDs who have "low" functioning capacities. There is a need to review studies sampling inclusion criteria as they may constitute a barrier for participation. Preference for sampling "high" functioning individuals may reinforce exclusion in research, and replicate broader patterns of socioeconomic exclusion of individuals with disabilities. Our discussion of inclusive research is informed by critical disability studies and the underlying principle "nothing about us without us."

Mothering children with developmental disabilities: A critical perspective on health promotion.

We present findings of a qualitative study exploring what constitutes relevant health promotion initiatives for immigrant mothers of children with developmental disabilities. We apply a social ecological approach, with a focus on gender-specific and transformative health promotion, to examine factors impacting mothers' health and wellbeing. Twenty-eight semi-structured and open-ended interviews were conducted with immigrant mothers in the greater Toronto area, Canada. Mothers identified facilitators, challenges, and strategies for their health promotion, providing relevant insights for meaningful intervention. Our findings show that immigrant mothers' health is influenced by intersecting social determinants of health, including migration status, gender, and disability.

Griefwork online: perinatal loss, lifecourse disruption and online support.

The Internet provides new opportunities for accessing and giving support following perinatal loss and in this article we report on a project concerned to explore the use of social networking and online networks following such an experience. Perinatal loss can be defined and perceived as biographical disruption yet this type of loss sometimes lacks social recognition. Our ethnographic study reveals that not only do mothers, and sometimes fathers and grandmothers, seek support on the Internet but they also engage in griefwork (the work the bereaved do with others).

The BLISS cluster randomised controlled trial of the effect of 'active dissemination of information' on standards of care for premature babies in England (BEADI) study protocol [ISRCTN89683698].

BACKGROUND: Gaps between research knowledge and practice have been consistently reported. Traditional ways of communicating information have limited impact on practice changes. Strategies to disseminate information need to be more interactive and based on techniques reported in systematic reviews of implementation of changes. There is a need for clarification as to which dissemination strategies work best to translate evidence into practice in neonatal units across England. The objective of this trial is to assess whether an innovative active strategy for the dissemination of neonatal research findings, recommendations, and national neonatal guidelines is more likely to lead to changes in policy and practice than the traditional (more passive) forms of dissemination in England. METHODS/DESIGN: Cluster randomised controlled trial of all neonatal units in England (randomised by hospital, n = 182 and stratified by neonatal regional networks and neonatal units level of care) to assess the relative effectiveness of active dissemination strategies on changes in local policies and practices. Participants will be mainly consultant lead clinicians in each unit. The intervention will be multifaceted using: audit and feedback; educational meetings for local staff (evidence-based lectures on selected topics, interactive workshop to examine current practice and draw up plans for change); and quality improvement and organisational changes methods. Policies and practice outcomes for the babies involved will be collected before and after the intervention. Outcomes will assess all premature babies born in England during a three month period for timing of surfactant administration at birth, temperature control at birth, and resuscitation team (qualification and numbers) present at birth.

Opportunity seized or missed? A case study of leadership and organizational change in the creation of a Care Trust.

This paper describes an action research study which focused on an exploration of the aspirations for and initial achievements of Stratham Mental Health NHS and Social Care Trust. Local leaders perceived that Stratham had a good history of health and social care partnership working and as such, adopted an integrationist view of culture to help shape the context of the new structural form. In doing so, consistency remained a key message to staff throughout this organizational transition and the change did not appear to cause the distraction to core business which the literature suggests it would do so. However, this continuity may have come at a cost, at least initially. In the process of formalizing the previous partnership into a Care Trust, Stratham may not have produced all the beneficial effects of synergy which are usually (albeit eventually) associated with mergers in the private sector. Certainly, local actors could see opportunities that had been missed. By focusing on the structural manifestation of the relationship, the opportunities to broaden informal horizontal linkages may have been underexploited. The study of Stratham serves to confirm that the integrationist conception of culture is limited and that the differentiation of professional groupings and the ambiguity of individual experience will always make contested the meanings that are attributed to organizational change.

Persistent organic pollutants in air and vegetation from the Canadian Rocky Mountains.

The exchange of chlorinated organic pollutants between air and vegetation in cold, mountain environments was investigated through the extraction of coniferous vegetation and high-volume air samples collected from the Canadian Rocky Mountains during the summers of 1999 and 2000. Concentrations of several compounds in vegetation increased as temperatures decreased, whereas atmospheric concentrations were not related to temperature. Daily cycling of these compounds between air and vegetation as a result of diurnal temperature changes was not observed. Compared with concentrations in vegetation from the Canadian Rocky Mountains, plant samples from the western valley in British Columbia (Canada) showed higher pollutant levels. Chemical partitioning between vegetation and air was not correlated with temperature, indicating that air contamination is governed by long-range transport and not by local revolatilization events. Based on these observations, we show that both deposition at higher altitudes and long-range atmospheric transport influence chemical accumulation in vegetation from the Canadian Rocky Mountains.

Clinical phenotype of families with longevity.

OBJECTIVES: To determine whether offspring of centenarians acquired protection from age-related diseases. DESIGN: Case-control study. SETTING: The study was part of the Longevity Genes Project at Albert Einstein College of Medicine. PARTICIPANTS: Centenarians (n=145), offspring of centenarians (n=180), and spouses of the offspring of centenarians (n=75) as a control group. Two additional groups served as controls: age-matched Ashkenazi Jews, and an age-matched control group from the Third National Health and Nutrition Examination Survey. MEASUREMENTS: Self-reported family history of longevity; prevalence of hypertension, diabetes mellitus, heart attacks, and strokes; and objective measurements of body mass index and fat mass. RESULTS: Parents of centenarians (born in approximately 1870) had a markedly greater ( approximately sevenfold) "risk" for longevity (reaching ages 90-99), supporting the notion that genetics contributed to longevity in these families. The offspring of long-lived parents had significantly lower prevalence of hypertension (by 23%), diabetes mellitus (by 50%), heart attacks (by 60%), and strokes (no events reported) than several age-matched control groups. CONCLUSION: Offspring of centenarians may inherit significantly better health. The authors suggest that a cohort of these subjects and their spouses is ideal to study the phenotype and genotype of longevity and its interaction with the environment.

Orographic cold-trapping of persistent organic pollutants by vegetation in mountains of western Canada.

Conifer needles from mountain areas of Alberta and British Columbia, Canada, were collected from sites that ranged in altitude from 770 to 2200 masl and were analyzed for polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCs) to determine if they are progressively concentrated in colder, more elevated mountain areas, where temperatures decrease as elevation increases. Concentrations of OCs in needles ranged from 43 to 2430 pg g(-1), 55-17500 pg g(-1), and 11-2930 pg g(-1) (dry weight), for total hexachlorocyclohexanes (HCHs), PCBs, and endosulfans, respectively. The more volatile OCs, with subcooled liquid vapor pressures (PL) > 0.1 Pa at 25 degrees C, increased at higher altitudes, whereas the less volatile OCs were either unrelated or inversely correlated with altitude. These spatial patterns were similar for species of spruce (Picea engelmannii and glauca) and pine (Pinus contorta and albicaulis). Back trajectories revealed that air masses arriving at these sites traveled over Asia and the Pacific Ocean before reaching the Rocky Mountains. Results from this study demonstrate that alpine ecosystems accumulate these chemicals to the same degree that is observed in polar environments that are known to receive contaminants by long-range transport.

Plasma HDL levels highly correlate with cognitive function in exceptional longevity.

BACKGROUND: Families of centenarians have high levels of plasma high-density lipoprotein (HDL) cholesterol, which may have neurological as well as cardiovascular protective effects during aging. Because plasma HDL level declines progressively with aging, we examined whether centenarians with higher plasma HDL levels have better cognitive function. METHODS: Total plasma cholesterol, low-density lipoprotein (LDL) cholesterol, HDL, triglycerides, and apolipoprotein levels were measured in a group of centenarians (N = 139; older than 95 years) and were correlated with their cognitive function (measured by Mini-Mental State Examination [MMSE]). RESULTS: Plasma HDL levels correlated significantly with MMSE (r =.32; p <.0001). Each decrease in plasma HDL tertile (74.9 +/- 2.1, 50.6 +/- 0.5, and 36.8 +/- 1.0 mg/dl) was associated with a significant decrease in MMSE (23.4 +/- 1.5, 17.7 +/- 1.8, and 12.4 +/- 1.8; p <.04 for each plasma HDL tertile). As expected, increased plasma apolipoprotein A-I and decreased plasma triglyceride levels were also correlated with a significantly superior cognitive function. Biological markers of hydration and nutritional status did not differ between the groups with the higher or lower plasma HDL or MMSE. CONCLUSIONS: These data demonstrate that cognitive dysfunction in centenarians is associated with a progressive decline in plasma HDL concentrations. This underscores the protective effects of increased plasma HDL and its role in maintaining superior cognition in longevity.
