RESUMEN

BACKGROUND: Scientific research has consistently emphasised the high levels of stress encountered by family caregivers of individuals living with dementia. However, conventional self-help approaches remain underutilised. The 'Diversity-On' study addresses this issue. The study employs a storytelling approach to develop and evaluate an online self-help program that is participatory and diversity-sensitive, thereby ensuring congruence with diverse identities and lifeworlds. METHODS: The study uses a mixed-methods design, comprising the allocation and implementation of the intervention, the development of stories, a process evaluation (N = 20) and an outcome evaluation (quantitative: N = 130, qualitative: N = 20). The study's primary focus is its comprehensive participatory approach, integrated throughout the research process. The study is dependent on the input of a number of stakeholders, all of whom are committed to advocating for the concerns of patients. DISCUSSION: Given its participatory methodology and intersectional perspective, the 'Diversity-On' study is anticipated to yield a number of significant outcomes. The study has the potential to empower family caregivers of individuals living with dementia who are under high stress, empowering them to take part in self-help groups despite multiple barriers, thus alleviating their burden. Additionally, it has the capacity to promote the well-being of caregiving relatives who are providing care and are experiencing high levels of stress. The study's objective is to maintain home care arrangements for as long as possible, in accordance with the values and preferences of care recipients and their families. The study intends to develop and assess a customised online self-help resource that is suitable for a diverse range of users and that remains accessible beyond the study period. TRIAL REGISTRATION: The project is subsequently registered in ClinicalTrials.gov.

RESUMEN

BACKGROUND: The psychological and cardiovascular health impacts on family members of patients who have been diagnosed with cancer have not been well characterized. The purpose of this study is to determine whether a family member's cancer diagnosis influences the risk of psychological illness and cardiovascular disease in first-degree relatives and spouses of patients affected by cancer. METHODS: This retrospective cohort analysis evaluated the risk of psychological illness and cardiovascular disease in first-degree relatives and spouses of patients diagnosed with a genitourinary cancer between 1990 and 2015 compared to relatives of those not diagnosed with a genitourinary cancer. The Utah Population Database was used and familial linkage was determined. Follow-up included 1-, 3-, and 5-year intervals. Patients residing outside of Utah and first-degree relatives and spouses with psychological or cardiovascular disease diagnosed before a family member's cancer diagnosis were excluded. RESULTS: A total of 49,284 patients with a genitourinary cancer were identified with 77,938 first-degree relatives and spouses. A matched control group included 246,775 patients with 81,022 first-degree relatives and spouses. Via Cox proportional hazards models, a 10% increased risk of developing a psychological illness (hazard ratio [HR], 1.10; 95% CI, 1.00-1.20) and a 28% increased risk of developing cardiovascular disease (HR, 1.28; 95% CI, 1.17-1.41) at 1 year after a family member's cancer diagnosis were found. CONCLUSIONS: This study provides population-level evidence to support the hypothesis that cancer diagnoses will lead to adverse health outcomes for family members of patients with cancer. Increased clinical attention and support are needed to reduce the harm to families caused by cancer.

RESUMEN

OBJECTIVE: The psychological consequences of being aware of an increased risk of developing abdominal aortic aneurysm as a first-degree relative of a person with abdominal aortic aneurysm are hitherto unexplored. This study investigates the awareness of heritability and anxiety in male and female adult offspring of abdominal aortic aneurysm patients compared to controls. Health-related quality of life among participants with aortic pathology was compared to participants with normal aortic diameters. METHODS: This was a cross-sectional point prevalence study based on the participants examined in the Detecting Abdominal Aortic Aneurysm in First Degree Relatives Trial (DAAAD; 752 adult offspring, 756 matched controls), 2020-2022. Questionnaires about health-related quality of life and study-specific questions regarding awareness of heritability were collected prior to the aortic ultrasound. RESULTS: Attendance rate was higher among individuals with heredity compared to controls (67% vs. 52%, p < 0.001). Of 1508 adult offspring examined, 65% reported having a close relative with abdominal aortic aneurysm (6% in controls). Female adult offspring reported higher awareness of heritability than controls (38% vs. 12%, p < 0.001), as did males (32% vs. 8%, p < 0.001). A slight majority of participants with awareness reported anxiety (54% of female offspring; 51% of male). There were no measured differences in health-related quality of life between the groups when standard health-related quality of life instruments were used. CONCLUSION: The higher-than-expected proportion of adult offspring with awareness of heritability and anxiety about such risk indicates that we fail to communicate risk to this group appropriately via the current channels of information within the healthcare system. This calls for the development of dedicated strategies for improved communication of abdominal aortic aneurysm risk to patients and their next of kin.

RESUMEN

The COVID-19 pandemic significantly interrupted the grieving experiences of bereaved families and drastically changed their ways of dealing with loss. Our study aims to gain an in-depth understanding of the experience of bereaved relatives of patients who died in palliative care units during the COVID-19 pandemic. The phenomenological research design included sixteen family members of hospitalized palliative patients who died from November 2021 to June 2022. The study involved conducting qualitative in-depth semi-structured interviews with family members 12-24 months after the death of their loved ones. The interviews aimed to gather information about the experiences of the families both before and after the death. The COREQ guidelines were applied in the study. Participants were mainly female (n = 13) with a mean age of 47.25 (SD = 12.58). Data were analysed using the Interpretative Phenomenology Analysis (IPA). The following three categories were identified: (1) navigating loved ones' final weeks and days (troubled deaths); (2) the last farewell was robbed; (3) looking for adjustment after loss. One overall main theme emerged, which was as follows: "Struggling between stolen moments and painful losses to get back into the flow of life". This study provides novel insights into end-of-life care and bereavement from the perspectives of family. Our findings suggest that developing and promoting family-centred culture can lead to compassionate palliative care focused on a myriad ways of affirming that their loved one matters.

RESUMEN

Obsessive-compulsive disorder (OCD) is characterized by structural alteration within white matter tissues of cortico-striato-thalamo-cortical, temporal and occipital circuits. However, the presence of microstructural changes in the white matter tracts of unaffected first-degree relatives of patients with OCD as a vulnerability marker remains unclear. Therefore, here, diffusion-tensor magnetic resonance imaging (DTI) data were obtained from 29 first-degree relatives of patients with OCD and 59 healthy controls. We investigated the group differences in FA using whole-brain analysis (DTI analysis). For additional regions of interest (ROI) analysis, we focused on the posterior thalamic radiation and sagittal stratum, shown in recent meta-analysis of patients with OCD. In both whole-brain and ROI analyses, using a strict statistical threshold (family-wise error rate [FWE] corrected p<.05 for whole-brain analyses, and p<.0125 (0.05/4) with Bonferroni correction for ROI analyses), we found no significant group differences in FA. Subtle reductions were observed in the anterior corona radiata, forceps minor, cingulum bundle, and corpus callosum only when a lenient statistical was applied (FWE corrected p<.20). These findings suggest that alterations in the white matter microstructure of first-degree relatives, as potential vulnerability markers for OCD, are likely subtle.

RESUMEN

An extensive body of evidence shows the impact of being the direct victim of a serious assault. However, much less is known about the impact on the family and close relatives of victims, who may be considered indirect victims. Based on analyses of the 2014 Adult Psychiatric Morbidity Survey, a face-to-face, cross-sectional probability-sample survey of 7519 adults aged 16 and over in England, this article estimates what proportion of the population was closely related to a victim of serious assault, and whether this experience was associated with a higher prevalence of feeling unsafe, depression and anxiety disorder, post-traumatic stress, self-harm, and suicidality. Descriptive and multivariable regression analyses were conducted, adjusting for complex survey design and potentially confounding factors. Results show that one in twenty adults (4.5%, n = 345) was closely related to a victim of serious assault (95% confidence interval (CI):4.0-5.2%). Close adult relatives of assault victims were more likely than the rest of the population to have been direct victims of violence and abuse themselves, to have experienced multiple other adversities, and to live in more deprived neighbourhoods. However, even when controlling for these experiences, relatives of victims had adjusted odds of feeling unsafe in the neighbourhood where they lived 2.36 times higher than the rest of the population (CI:1.26-4.44), and their odds of having a depressive or anxiety disorder were 1.37 times higher (0.99-1.90). These analyses indicate that relatives in England may already be vulnerable, with potential to also be further affected by the experiences of family members. To more fully account for the effects of violence in society, research with indirect victims of serious violence in the context of their own experiences of direct victimization and wider adversities is required. This could be factored into a broader remit for victim support services which includes support for victims' families.

RESUMEN

BACKGROUND: We aimed to synthesize the qualitative evidence on the impacts of COVID-19-related restricted family presence policies from the perspective of patients, families, and healthcare professionals from neonatal (NICU), pediatric (PICU), or adult ICUs. METHODS: We searched MEDLINE, EMBASE, Cochrane Databases of Reviews and Clinical Trials, CINAHL, Scopus, PsycINFO, and Web of Science. Two researchers independently reviewed titles/abstracts and full-text articles for inclusion. Thematic analysis was completed following appraising article quality and assessing confidence in the individual review findings using standardized tools. RESULTS: We synthesized 54 findings from 184 studies, revealing the impacts of these policies in children and adults on: (1) Family integrated care and patient and family-centered care (e.g., disruption to breastfeeding/kangaroo care, dehumanizing of patients); (2) Patients, families, and healthcare professionals (e.g., negative mental health consequences, moral distress); (3) Support systems (e.g., loss of support from friends/families); and (4) Relationships (e.g., loss of essential bonding with infant, struggle to develop trust). Strategies to mitigate these impacts are reported. CONCLUSION: This review highlights the multifaceted impacts of restricted visitation policies across distinct care settings and strategies to mitigate the harmful effects of these policies and guide the creation of compassionate family presence policies in future health crises.

RESUMEN

Objective: Hypoglycemia constitutes a communication barrier between youth with type 1 diabetes, their family members and health professionals. A narrative tool may contribute to a more effective communication. Methods: Semi-structured interviews with six open-ended questions using narrative techniques collect and analyze (thematic and comparative analysis) different ways of "naming" the lived experience of hypoglycemia. Results: 103 participants, 40 with type 1 Diabetes aged 10-18 years (17 female), 63 relatives (40 female). Group 1 (G1), 10-14 years old (n = 21), Group 2 (G2), 15-18 years old (n = 19), Group 3 (G3) relatives, 30-59 years old. G3 was divided, G3.1: female (n = 42) and G3.2: male (n = 21).G1 and G2 presents greater attention to symptoms. G1 refers a greater need for help, G2 emphasizes autonomy. G2 and G3 describes better the medical protocol. G1 and G2 refer more topics such as "discomfort", "frustration", "obligation", "difficulty in verbalizing", G3 refers to "gilt", "fear" and "responsibility". G3.1 refer more "symptoms", "responsibility", "fault", "incapacity". Conclusions: A narrative tool enhances the singularity of a common experience, proving itself useful to adolescents, relatives, and healthcare professionals. Practice implications: In addition to gathering information that is usually acquired empirically, a narrative tool exposes knowledge gaps and may allow implementing intervention strategies.

RESUMEN

PURPOSE: This study was conducted to determine stigma and attitudes in the relatives of patients with epilepsy and the factors affecting them. METHODS: This descriptive and cross-sectional study was conducted with 173 relatives of patients with epilepsy who were admitted to the neurology outpatient clinic of a university hospital in Van Province, eastern Turkey, between April and December 2021. Individual information forms, the Epilepsy Stigma Scale Patient's Relative, and the Epilepsy Attitude Scale were used to collect the data. RESULTS: The mean stigma score was 54.58 (standard deviation [SD] = 10.96), and the mean attitude score was 53.05 (SD = 8.14). A negative and significant correlation was found between stigma score and attitude score (r = -0.457, p < 0.001). It was found that stigma and attitude scores differed significantly in terms of education, hiding epilepsy, and the idea that epilepsy is related to spiritual thoughts (p < 0.05). CONCLUSION: As a result of this study, it was found that the relatives of patients with epilepsy were generally moderately stigmatized (64.8 %) and had moderate attitudes toward epilepsy. As the stigma increased in the participants, it was determined that they showed more negative attitudes toward epilepsy. The results indicated that relatives of patients with epilepsy who had one or more seizures per month experienced more stigma, and relatives of patients with epilepsy who did not take their medication regularly exhibited a more negative attitude toward epilepsy.

RESUMEN

Wild Malus species flourished in North America long before Europeans introduced domesticated apples. Malus coronaria and M. ioensis are native to the mid-western and eastern USA, while M. angustifolia and M. fusca grow in the southeast and west, respectively. They offer disease resistance, climate and soil adaptability, and horticultural traits for apple breeding. However, their utilization remains limited due to insufficient genomic resources and specific genetics. We report high-quality phased chromosome-scale assemblies of M. coronaria and M. ioensis, generated using long-read and conformation capture sequencing. Phylogenetic and synteny analysis indicated high relatedness between these two genomes and previously-published genome of M. angustifolia, and lower relatedness with M. fusca. Gene family-based pangenome of North American Malus identified 60,211 orthogroups containing 340,087 genes. Genes involved in basic cellular and metabolic processes, growth, and development were core to the existence of these species, whereas genes involved in secondary metabolism, stress response, and interactions with other organisms were accessory and are likely associated with adaptation to specific environments. Structural variation hotspots were mostly overlapping with high gene density. This study offers novel native North American Malus genome resources that can be used to identify genes for apple breeding and understand their evolution and adaptation.

RESUMEN

Utilization of crop wild relatives of wheat can be very effective in building the genetic diversity to cater to the evolving strains of disease pathogens. Aegilops speltoides is a rich source of rust resistance genes however transferring those to wheat genome can be tedious due to co-transfer and preferential transmission of undesirable genes causing gametocidal activity. Such an unholy association was observed in Triticum aestivum-Ae. speltoides derivative line Sel. 2427 which possess the broad-spectrum leaf rust seedling resistance gene (LrS2427). Molecular analysis based on 35 K wheat breeder's array revealed the maximum percentage of Ae. speltoides genome introgression on homoeologous group 2. In situ hybridization studies revealed the presence of S genome in Sel. 2427, showing six translocations on four chromosomes. Karyotyping using repetitive probe (AAG)6 revealed that the two chromosomes involved are 2D and 2B. Genic regions causing gametocidal activity were identified by dissecting it into component traits and QTLs on 2D and 2B chromosomes were revealed in case of the trait seed shrivelling index. To break the inadvertent association of LrS2427 with gametocidal genes, F1(Agra Local X Sel. 2427) seeds were irradiated with gamma rays and stable leaf rust resistant mutants lacking gametocidal activity were developed. These mutants showed resistance to different races of leaf rust pathogen and showed superior agronomic performance as well. These mutants could be a great resource in wheat improvement for utilization of the leaf rust resistance gene LrS2427 without any yield penalty.

RESUMEN

Family reactions to coming out can affect the mental health of individuals who disclose their sexual orientation or gender identity. Therefore, it is important to have an appropriate tool to assess them. The Perceived Parental Reactions Scale (PPRS) assessed perceived parental reactions to the disclosure of gay, lesbian, or bisexual sexual orientation by their children. We adapted the PPRS so that it can be answered by any individual belonging to a sexual or gender minority, and can be answered regarding any member of the family, not just parents. A total of 2627 individuals from Spain participated in this study, with a mean age of 31.59 (SD = 11.26). Participants completed the adapted PPRS questionnaire, now named the Family Reaction to Coming Out (FRCO). The FRCO assessed family reactions when disclosing their sexual orientation or gender identity. The majority of participants identified as cisgender men (47.5%) or cisgender women (44.9%), and as gay/lesbian (51.9%). A one-factor model emerged through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The FRCO displayed excellent internal consistency and demonstrated good levels of invariance for participants' gender (male vs female vs nonbinary gender), family member's gender (male vs female), and type of family member (parents vs other family member). Supporting convergent validity, the FRCO has shown a positive correlation with fear of family reaction to coming out. These findings support the validity and reliability of the FRCO tool in assessing the reactions of any family member within the Spanish context.

RESUMEN

The Arabian Peninsula, with its rugged mountains, wadis, alluvial plains, sand dune deserts, and diverse coastlines, spans over 3 million km2. The Peninsula is situated at the crossroads of Africa and Asia and is a meeting point for diverse biogeographic realms, including the Palearctic, Afrotropical, and Indomalayan regions. This convergence of biogeographic zones has resulted in a remarkably diverse flora and fauna, which is adapted to the harsh and varied climates found throughout the Peninsula. Each of the countries of the Arabian Peninsula are biologically diverse and unique in their own right, but Yemen, Saudi Arabia, and Oman are the most diverse in terms of their landforms and biological diversity. The mountainous regions support a cooler and more moderate climate compared to the surrounding lowlands, thus forming unique ecosystems that function as refugia for plant and animal species, and have a high endemism of plant species. The desert ecosystems support a variety of lifeforms that are specially adapted to an extreme arid climate. Due to its long history of human habitation and subsistence agriculture, particularly in the mountainous areas, the Arabian Peninsula possesses unique crop varieties adapted to extreme arid climates, making them important genetic resources for the future in the face of climate change. The Arabian Peninsula, though rich and diverse in its biological diversity, has been greatly affected by human activities, especially in the last 50 years, including urbanization, habitat destruction, overgrazing, and climate change, which pose significant threats to the biodiversity of the region. This review presents the biogeography and background of conservation efforts made in the countries in the Arabian Peninsula and gives the progress made in botanical research and conservation practices throughout the Peninsula.

RESUMEN

Verbal fluency (VF) has been proposed as a putative neurocognitive endophenotype in schizophrenia (SZ) and bipolar disorder (BD). However, this hypothesis has not been examined using a longitudinal family approach. We conducted a five-group, comparative study. The sample comprised 323 adult participants, including 81 BD patients, 47 unaffected relatives of BD BD-Rel), 76 SZ patients, 40 unaffected relatives of SZ (SZ-Rel), and 79 genetically unrelated healthy controls (HC). All subjects were assessed twice with semantic VF (sem-VF) and phonological VF (ph-VF) tests over a 2-year follow-up period. ANCOVAs controlling for age and years of education were used to compare performance across groups. Patients with SZ and BD and their unaffected relatives showed sem-VF and ph-VF deficits at baseline, which persisted over time (all, p < 0.05). Moreover, BD-Rel showed an intermediate performance between SZ and HC. A repeated-measures ANOVA revealed no significant differences in the between-group trajectories comparison (p > 0.05). Our findings support that VF may represent a neurocognitive endophenotype for SZ and BD. Further longitudinal, family studies are warranted to confirm this preliminary evidence.

RESUMEN

BACKGROUND: Relatives of individuals with bipolar disorder (BD) are at higher risk of developing the disorder. Identifying brain alterations associated with familial vulnerability in BD can help discover endophenotypes, which are quantifiable biological traits more prevalent in unaffected relatives of BD (BD-RELs) than the general population. This review aimed at expanding our knowledge on endophenotypes of BD by providing an overview of resting-state functional magnetic resonance imaging (rs-fMRI) alterations in BD-RELs. METHODS: A systematic search of PubMed, Scopus, and Web of Science was performed to identify all available rs-fMRI studies conducted in BD-RELs up to January 2024. A total of 18 studies were selected. Six included BD-RELs with no history of psychiatric disorders and 10 included BD-RELs that presented psychiatric disorders. Two investigations examined rs-fMRI alterations in BD-RELs with and without subthreshold symptoms for BD. RESULTS: BD-RELs presented rs-fMRI alterations in the cortico-limbic network, fronto-thalamic-striatal circuit, fronto-occipital network, and, to a lesser extent, in the default mode network. This was true both for BD-RELs with no history of psychopathology and for BD-RELs that presented psychiatric disorders. The direct comparison of rs-fMRI alterations in BD-RELs with and without psychiatric symptoms displayed largely non-overlapping patterns of rs-fMRI abnormalities. LIMITATIONS: Small sample sizes and the clinical heterogeneity of BD-RELs limit the generalizability of our findings. CONCLUSIONS: The current literature suggests that first-degree BD-RELs exhibit rs-fMRI alterations in brain circuits involved in emotion regulation, cognition, reward processing, and psychosis susceptibility. Future studies are needed to validate these findings and to explore their potential as biomarkers for early detection and intervention.

RESUMEN

Complete chloroplast genomes of 17 samples from six species of Colocasia (Araceae) were sequenced, assembled, and aligned together with two previously reported complete genome sequences from taro (Colocasia esculenta). Analysis provides a well-supported phylogenetic tree for taro and closely-related wild Colocasia species in Southeast Asia. Two chloroplast lineages (CI and CII) form a well-defined haplotype group and are found in cultivated taros known as var. esculenta (dasheen, CI), var. antiquorum (eddoe, CII), and in a widespread, commensal wild form known as var. aquatilis (CI). A third lineage (CIII) is also found in wild taros known as var. aquatilis and in the wild species C. lihengiae, C. formosana, and C. spongifolia. We suggest three different scenarios to explain the grouping of CIII wild taros (C. esculenta) with other wild Colocasia species. Chloroplast lineages CI and CIII in C. esculenta and an unknown parent species may be involved in an as yet undated history of hybridization, chloroplast capture, and range extension. Substantial taxonomic revision may be needed for C. esculenta after further studies of morphological and genetic diversity within the crop, in wild populations, and in closely related wild species. The results also point to the Bengal delta as a region of key interest for future research on the origins of tropical wetland taros.

RESUMEN

Individuals with schizophrenia (SZ) or bipolar disorder (BP) display cognitive impairments, while their first-degree relatives perform at an intermediate level between the patient groups and controls. However, the environmental impact of having an ill relative likely varies with the type of kinship and some studies suggest that offspring may be particularly disadvantaged. The present study aimed to investigate the relationship between parent and child cognition in parents with SZ or BD and their 7-year-old offspring. A population-based cohort of 522 children (parental SZ, n = 202; parental BP, n = 120; controls, n = 200) and their parents underwent the same assessment battery covering a wide range of cognitive functions. We used Bayesian statistics to model performance. We found that performance on non-verbal tests was better in offspring than parents with SZ or BP, using the controls as reference. However, for verbal tests, there was little to no evidence for this pattern or even some evidence for the opposite in the BP group: relatively better performance in parents than offspring. The findings suggest that the offspring of parents with SZ or BP may be particularly disadvantaged in verbal abilities. Future studies will show whether this pattern persists throughout development.

RESUMEN

BACKGROUND: The economic importance of the globally distributed Brassicaceae family resides in the large diversity of crops within the family and the substantial variety of agronomic and functional traits they possess. We reviewed the current classifications of crop wild relatives (CWRs) in the Brassicaceae family with the aim of identifying new potential cross-compatible species from a total of 1,242 species using phylogenetic approaches. RESULTS: In general, cross-compatibility data between wild species and crops, as well as phenotype and genotype characterisation data, were available for major crops but very limited for minor crops, restricting the identification of new potential CWRs. Around 70% of wild Brassicaceae did not have genetic sequence data available in public repositories, and only 40% had chromosome counts published. Using phylogenetic distances, we propose 103 new potential CWRs for this family, which we recommend as priorities for cross-compatibility tests with crops and for phenotypic characterisation, including 71 newly identified CWRs for 10 minor crops. From the total species used in this study, more than half had no records of being in ex situ conservation, and 80% were not assessed for their conservation status or were data deficient (IUCN Red List Assessments). CONCLUSIONS: Great efforts are needed on ex situ conservation to have accessible material for characterising and evaluating the species for future breeding programmes. We identified the Mediterranean region as one key conservation area for wild Brassicaceae species, with great numbers of endemic and threatened species. Conservation assessments are urgently needed to evaluate most of these wild Brassicaceae.

RESUMEN

PURPOSE: The aim of this study was to investigate the experiences of living with glioblastoma from the perspective of patients themselves as well as their closest relatives, focusing on the changes in the life situation and the need for support. METHODS: Twenty-two semi-structured interviews were conducted with 12 patients (mean age 61 years, 7 male, 5 female) and 10 relatives (mean age 56 years, 3 male, 7 female). The relatives comprised of partners (n = 7), child (n = 1), sister (n = 1), or friend (n = 1). Questions focused on changes in the life situation and support needed to face these changes. Data was analyzed using inductive qualitative content analysis (QCA). RESULTS: Living with glioblastoma dramatically changes the lives of both patients and relatives. Cognitive symptoms (e.g., speech and memory disturbances), deterioration of physical function (e.g., paresis), and psychological function (e.g., behavioral changes, anxiety) can lead to impaired family dynamics, social isolation, and fear of the future. Support from other family members, friends, and healthcare professionals is crucial. Timely, tangible, and easily available support from the healthcare system the entire disease trajectory is sought after, enabling individualized care with emotional support, clearer information, and faster feedback. CONCLUSION: The changes in life situations faced by patients with glioblastoma and their closest relatives are dramatic and underline the importance of providing integrated care throughout the entire healthcare continuum, encompassing specialist neuro-oncological care, municipal support, and palliative care. Individualized support for both patients and relatives can enhance the sense of safety amid the chaos in their life situation.
