The loss of genetic and life history diversity has been documented across many taxonomic groups, and is considered a leading cause of increased extinction risk. Juvenile salmon leave their natal rivers at different sizes, ages and times of the year, and it is thought that this life history variation contributes to their population sustainability, and is thus central to many recovery efforts. However, in order to preserve and restore diversity in life history traits, it is necessary to first understand how environmental factors affect their expression and success. We used otolith (87)Sr/(86)Sr in adult Chinook salmon (Oncorhynchus tshawytcha) returning to the Stanislaus River in the California Central Valley (USA) to reconstruct the sizes at which they outmigrated as juveniles in a wetter (2000) and drier (2003) year. We compared rotary screw trap-derived estimates of outmigrant timing, abundance and size with those reconstructed in the adults from the same cohort. This allowed us to estimate the relative survival and contribution of migratory phenotypes (fry, parr, smolts) to the adult spawning population under different flow regimes. Juvenile abundance and outmigration behavior varied with hydroclimatic regime, while downstream survival appeared to be driven by size- and time-selective mortality. Although fry survival is generally assumed to be negligible in this system, >20% of the adult spawners from outmigration year 2000 had outmigrated as fry. In both years, all three phenotypes contributed to the spawning population, however their relative proportions differed, reflecting greater fry contributions in the wetter year (23% vs. 10%) and greater smolt contributions in the drier year (13% vs. 44%). These data demonstrate that the expression and success of migratory phenotypes vary with hydrologic regime, emphasizing the importance of maintaining diversity in a changing climate.

Background: Informal caregivers are key support for patients with progressive incurable diseases. However, their own needs often remain unmet. Therefore, we developed, manualised and implemented the intervention "Being an informal caregiver - strengthening resources" aiming to support and empower informal caregivers by addressing relevant information-related, physical, psychological and social needs., Methods: In this pilot study, we evaluated the acceptance and experiences with this psychoeducational intervention. The study was conducted over two years (2019-2021). Informal caregivers were recruited from the University Medical Centre Hamburg-Eppendorf and the metropolitan region of Hamburg, Germany. The intervention was aimed at adult persons who identified themselves as an informal caregiver to an adult patient with a progressive incurable cancer and non-cancer disease. For the evaluation we used a mixed methods approach, combining a longitudinal questionnaire survey (pre-intervention, after each module, 3-months follow-up) and semi-structured interviews post-intervention. Quantitative data were analysed using descriptive statistics and a paired t-Test, interviews were analysed based on the qualitative content analysis according to Mayring. Results were triangulated using a convergent triangulation design., Results: Of 31 informal caregivers who received the intervention, 25 returned the follow-up questionnaire and 20 informal caregivers were interviewed. Triangulated results showed a high satisfaction with the implementation of the intervention. Of a broad range of subjective benefits, gaining knowledge, self-awareness and self-efficacy were most apparent. Informal caregivers reported improved preparedness, awareness of own needs as well as confidence regarding handling own emotions and interacting with the ill person. However, implementing the learned skills into daily life can be challenging due to internal and external factors. Motivations and challenges for participating as well as potential for improvement were identified., Conclusions: This pilot study showed an overall positive evaluation and several subjective benefits of the psychoeducational intervention "Being an informal caregiver - strengthening resources". Further research is needed to measure the efficacy of this intervention on informal caregivers' outcomes. Therefore, a multicentre randomized prospective study is planned., (© 2024. The Author(s).)

Background: The COVID pandemic is an example of a crisis challenging healthcare systems worldwide. The impact of the pandemic on providing high-quality palliative care calls for a deeper understanding of specialist services during crises. This is essential in preparation for further crises., Aim: To develop a conceptual understanding of the impact of the pandemic on specialist palliative care as an example for arising future crises., Design: Qualitative interview study across Germany, following a constructivist grounded theory methodology., Setting/participants: Eleven semi-structured interviews with experts with overarching knowledge of structures and processes in specialist palliative care between 05-07/2020 and between 02-06/2021, 23 semi-structured interviews with healthcare professionals working in a specialist palliative care setting., Results: The complex system of palliative care provision during crises has properties that cannot be understood as separated parts of the care process. The pandemic led to unique structural and processual challenges characterized by interconnectedness, uncertainty, dynamic, underlying dilemmas, and unclear long-term goal. In response to the pandemic, teams experienced different phases, which enhanced adaption, innovation, and progress within complex care situations. Creative strategy approaches and dynamic responsiveness facilitated innovative development and could lead to long-lasting improvement within services. Availability of information, transparent communication, comprehensible instructions, participation in decision-making, and search for solutions contributed to teams' proactive development throughout the pandemic., Conclusion: Addressing the complex problems in specialist palliative care caused by crises requires system thinking and a learning mindset. This can facilitate teams to overcome the crisis and move forward rather than bounce back to normal., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Specialist palliative home care (SPHC) aims to maintain and improve patients' quality of life in the community setting. Symptom burden may differ between oncological and non-oncological patients. However, little is known about diagnosis-related differences of SPHC patients. This study aims to describe the prevalence of physical symptom burden and psychosocial problems of adult patients in SPHC, and to evaluate diagnosis-related symptom clusters., Methods: Secondary analysis of data from a prospective, cross-sectional, multi-centre study on complexity of patients, registered at the German Register for Clinical Studies (DRKS trial registration number: DRKS00020517, 12/10/2020). Descriptive statistics on physical symptom burden and psychosocial problems at the beginning of care episodes. Exploratory and confirmatory factor analyses to identify symptom and problem clusters., Results: Seven hundred seventy-eight episodes from nine SPHC teams were included, average age was 75 years, mean duration of episode 18.6 days (SD 19.4). 212/778 (27.2%) had a non-oncological diagnosis. Main burden in non-oncological episodes was due to poor mobility (194/211; 91.9%) with significant diagnosis-related differences (χ² = 8.145, df = 1, p = .004; oncological: 472/562; 84.0%), and due to weakness (522/565; 92.4%) in oncological episodes. Two symptom clusters (psychosocial and physical) for non-oncological and three clusters (psychosocial, physical and communicational/practical) for oncological groups were identified. More patients in the non-oncological group compared to the oncological group showed at least one symptom cluster (83/212; 39.2% vs. 172/566; 30.4%)., Conclusion: Patients with non-oncological diseases had shorter episode durations and were more affected by symptom clusters, whereas patients with oncological diseases showed an additional communicational/practical cluster. Our findings indicate the high relevance of care planning as an important part of SPHC to facilitate anticipatory symptom control in both groups., (© 2023. The Author(s).)

Purpose: Modern, personalized treatment concepts in oncology require an interdisciplinary and multiprofessional collaboration. In addition to its relevance in patient care, interdisciplinary collaboration is also becoming increasingly important in clinical research as well as medical education and resident training in oncology., Methods: Between November 2021 and March 2022, an online survey was conducted among German early career research groups, represented by Young Oncologists United (YOU). The aim was to identify the status and need for interdisciplinarity at clinic, educational, and research levels., Results: A total of 294 participants completed the questionnaire in full. 90.7% of the respondents fully or predominantly agreed with the statement that interdisciplinary work plays a major role in their daily clinical work. 78.9% wished for more interdisciplinary collaboration. Of the 49.7% of participants who have never participated in an interdisciplinary research project, 80.1% said they would like to participate in such a study project in the future. Lack of time resources, too much organizational effort, and possible political conflicts between institutions were identified as factors that make practical implementation difficult. 74.1% declared their willingness to become active in an oncology early career research group., Conclusion: Interdisciplinary collaboration has become increasingly important in oncology. Networks that span different disciplines could help to promote interdisciplinary research projects among young scientists and improve exchange in professional practice and education with the implication of improved patient care., (© 2023.

Background: This study examined care needs and utilisation of psychosocial support services among parents of children who had received specialist paediatric palliative care, as well as the relationship between need fulfilment and grief. Possible differences between parents of children who died of cancer versus a non-cancer disease were explored., Methods: This exploratory study, conducted in two specialist paediatric palliative care facilities, included parents who had lost a child within a period of 0.5 to 8 years before this investigation. From the bereavement perspective, parents reported their needs during paediatric palliative care using the Family Inventory of Needs - Peadiatric II (FIN-PED II). Utilisation of psychosocial support services during paediatric palliative care and after the child's death, as well as potential barriers to accessing services were assessed. Grief symptoms were measured using the Inventory of Complicated Grief - German Version (ICG-D)., Results: Overall, 56 of 157 approached parents participated in the study. Mean time interval after the child's death was 3.2 years. Of the 17 FIN-PED II needs, 13 needs were reported to be very/extremely important to more than 75% of the parents each. Highest ranked needs related to asking questions at any time (100%), sincere care for the child (100%), and information about changes in the child's condition (98%). The highest ranked unmet needs related to hope (61%), interactions with siblings (41-42%), and trust in the health care system (39%). Comparisons showed no significant differences between parents whose child died of cancer (n = 18) versus a non-cancer disease (n = 38). During paediatric palliative care, 61% of the parents had accessed at least one psychosocial support service and 84% had done so after the child's death. The most prominent barriers for accessing services were sufficient informal support (38%), no subjective need (23%), and lack of time (20%). Overall, 52% of the parents showed noticeable symptoms for complicated grief (ICG-D > 25). A higher level of grief symptoms significantly correlated with a lower fulfilment of the need to say goodbye to the child (p = .042) with a medium correlational effect., Conclusions: Our findings may help to guide health care professionals in their assessment of parental needs and provision of support to parents during paediatric palliative care., (© 2022.

Objectives: The heterogeneity of specialist palliative care services requires a classification to enable a clear description and comparison. In Germany, specialist palliative care is provided by palliative care units, palliative care advisory teams in hospitals and palliative home care teams. The differentiation between the three care settings can serve as a first level of classification. However, due to profound variations in regulatory structures and financing systems, services within each setting are heterogeneous and characteristics remain unclear, which impedes quality management. Further characteristics of specialist palliative care models need to be considered to allow for differentiation. Thus, services should be described on a polyhierarchical basis, such as a typology, representing relevant characteristics. We aimed at the development of a comprehensive classification to facilitate the description and differentiation of specialist palliative care models., Methods: Qualitative study including the development of a literature based, preliminary list of structural and processual characteristics, expert interviews and focus groups. Eleven interviews from May to June 2020 and two focus groups, with seven and nine participants each, in January 2021., Results: Several structure and process characteristics were identified as suitable features for the specification of specialist palliative care in Germany. A classification in form of a typology including relevant characteristics has been developed., Conclusions: The advanced typology refines the existing level of differentiation within specialist palliative care services in Germany and paves the way for an improved understanding of services. This deeper insight into structure and process characteristics of specialist palliative care is necessary internationally., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: A casemix classification based on patients' needs can serve to better describe the patient group in palliative care and thus help to develop adequate future care structures and enable national benchmarking and quality control. However, in Germany, there is no such an evidence-based system to differentiate the complexity of patients' needs in palliative care. Therefore, the study aims to develop a patient-oriented, nationally applicable complexity and casemix classification for adult palliative care patients in Germany., Methods: COMPANION is a mixed-methods study with data derived from three subprojects. Subproject 1: Prospective, cross-sectional multi-centre study collecting data on patients' needs which reflect the complexity of the respective patient situation, as well as data on resources that are required to meet these needs in specialist palliative care units, palliative care advisory teams, and specialist palliative home care. Subproject 2: Qualitative study including the development of a literature-based preliminary list of characteristics, expert interviews, and a focus group to develop a taxonomy for specialist palliative care models. Subproject 3: Multi-centre costing study based on resource data from subproject 1 and data of study centres. Data and results from the three subprojects will inform each other and form the basis for the development of the casemix classification. Ultimately, the casemix classification will be developed by applying Classification and Regression Tree (CART) analyses using patient and complexity data from subproject 1 and patient-related cost data from subproject 3., Discussion: This is the first multi-centre costing study that integrates the structure and process characteristics of different palliative care settings in Germany with individual patient care. The mixed methods design and variety of included data allow for the development of a casemix classification that reflect on the complexity of the research subject. The consecutive inclusion of all patients cared for in participating study centres within the time of data collection allows for a comprehensive description of palliative care patients and their needs. A limiting factor is that data will be collected at least partly during the COVID-19 pandemic and potential impact of the pandemic on health care and the research topic cannot be excluded., Trial Registration: German Register for Clinical Studies trial registration number: DRKS00020517 ., (© 2022.

Objective: Considering the risk of spiritual distress among terminally ill patients, experts long agree that spiritual care has to be an integral component of palliative care. Despite this consensus, the role of spirituality among family caregivers remains largely unexplored. We aimed to describe how spirituality manifests in the lived experience of family caregivers (FCs) in a palliative care context., Method: As part of a secondary analysis, data derived from two qualitative primary studies on FCs' burdens and needs in the context of caring for a patient with a diagnosis of incurable cancer. Previously transcribed interviews were examined by means of a thematic analysis, transcending the focus of the primary studies to examine how spirituality arises and/or persists in the life of FCs from the time of diagnosis of incurable cancer up until bereavement., Results: Twenty-nine narratives were explored and all included spirituality as a relevant theme. Analysis revealed four aspects associated with the presence of spirituality among FCs' experiences: "Connectedness," "Religious Faith," "Transcendence," "Hope," and a fifth overarching aspect which we named "Ongoing integration of spiritual experience." Spirituality appeared as a multilayered phenomenon and was shaped individually among FCs' narratives., Significance of Results: In view of the results, exploring and discussing spirituality and underlying experiences in the situation as an FC seems likely to widen the perspective on FCs' problems and needs. Further research on spiritual needs among FCs of patients with incurable life-limiting cancer is deemed necessary.
