RESUMEN

Inositol 1,4,5-trisphosphate receptors (IP3Rs) are one of the two types of tetrameric ion channels that release calcium ion (Ca2+) from the endoplasmic reticulum (ER) into the cytosol. Ca2+ released via IP3Rs is a fundamental second messenger for numerous cell functions. Disturbances in the intracellular redox environment resulting from various diseases and aging interfere with proper calcium signaling, however, the details are unclear. Here, we elucidated the regulatory mechanisms of IP3Rs by protein disulfide isomerase family proteins localized in the ER by focusing on four cysteine residues residing in the ER lumen of IP3Rs. First, we revealed that two of the cysteine residues are essential for functional tetramer formation of IP3Rs. Two other cysteine residues, on the contrary, were revealed to be involved in the regulation of IP3Rs activity; its oxidation by ERp46 and the reduction by ERdj5 caused the activation and the inactivation of IP3Rs activity, respectively. We previously reported that ERdj5 can activate the sarco/endoplasmic reticulum Ca2+-ATPase isoform 2b (SERCA2b) using its reducing activity [Ushioda et al., Proc. Natl. Acad. Sci. U.S.A. 113, E6055-E6063 (2016)]. Thus, we here established that ERdj5 exerts the reciprocal regulatory function for IP3Rs and SERCA2b by sensing the ER luminal Ca2+ concentration, which contributes to the calcium homeostasis in the ER.

RESUMEN

Brassinazole Resistant 1 (BZR1) and bri1 EMS Suppressor 1 (BES1) are key transcription factors that mediate brassinosteroid (BR)-responsive gene expression in Arabidopsis. The BZR1/BES1 family is composed of BZR1, BES1, and four BES1/BZR1 homologs (BEH1-BEH4). However, little is known about whether BEHs are regulated by BR signaling in the same way as BZR1 and BES1. We comparatively analyzed the functional characteristics of six BZR1/BES1 family members and their regulatory mechanisms in BR signaling using genetic and biochemical analyses. We also compared their subcellular localizations regulated by the phosphorylation status, interaction with GSK3-like kinases, and heterodimeric combination. We found that all BZR1/BES1 family members restored the phenotypic defects of bri1-5 by their overexpression. Unexpectedly, BEH2-overexpressing plants showed the most distinct phenotype with enhanced BR responses. RNA-Seq analysis indicated that overexpression of both BZR1 and BEH2 regulates BR-responsive gene expression, but BEH2 has a much greater proportion of BR-independent gene expression than BZR1. Unlike BZR1 and BES1, the BR-regulated subcellular translocation of the four BEHs was not tightly correlated with their phosphorylation status. Notably, BEH1 and BEH2 are predominantly localized in the nucleus, which induces the nuclear accumulation of other BZR1/BES1 family proteins through heterodimerization. Altogether, our comparative analyses suggest that BEH1 and BEH2 play an important role in the functional interaction between BZR1/BES1 family transcription factors.

RESUMEN

BACKGROUND: Siblings of children with cancer may experience adverse household economic consequences, but their financial outcomes in adulthood are unknown. METHODS: A total of 880 siblings (aged 18-64 years) of adult-aged childhood cancer survivors were surveyed to estimate the prevalence of financial hardship by three established domains (behavioral, material, and psychological). For individual financial hardship items matching the contemporaneous National Health Interview Survey or Behavioral Risk Factor Surveillance System, siblings were compared with the general population by calculating adjusted prevalence odds ratios (ORs) to sample-weighted responses. Multivariable logistic regression models examined associations between sibling characteristics and each hardship domain and between sibling hardship and survivors' cancer/treatment characteristics. RESULTS: Behavioral, material, and psychological hardship was reported by 24%, 35%, and 28%, respectively. Compared with national survey respondents, siblings were more likely to report worries about medical bills (OR, 1.14; 95% confidence interval [CI], 1.06-1.22), difficulty affording nutritious foods (OR, 1.79; 95% CI, 1.54-2.07), and forgoing needed medical care (OR, 1.38; 95% CI, 1.10-1.73), prescription medications (OR, 2.52; 95% CI, 1.99-3.20), and dental care (OR, 1.34; 95% CI, 1.15-1.57) because of cost. Sibling characteristics associated with reporting financial hardship in one or more domains included female sex, older age, chronic health conditions, lower income, not having health insurance, high out-of-pocket medical expenditures, and nonmedical/nonhome debt. No survivor cancer/treatment characteristics were associated with sibling financial hardship. CONCLUSIONS: Adult siblings of childhood cancer survivors were more likely to experience financial hardship compared with the general population. Childhood cancer may adversely affect entire households, with potentially lasting implications.

RESUMEN

Negative feedback loops represent a regulatory mechanism that guarantees that signaling thresholds are compatible with a physiological response. Previously, we established that Lrig1 acts through this mechanism to inhibit Ret activity. However, it is unclear whether other Lrig family members play similar roles. Here, we show that Lrig1 and Lrig3 are co-expressed in Ret-positive mouse dorsal root ganglion (DRG) neurons. Lrig3, like Lrig1, interacts with Ret and inhibits GDNF/Ret signaling. Treatment of DRG neurons with GDNF ligands induces a significant increase in the expression of Lrig1 and Lrig3. Our findings show that, whereas a single deletion of either Lrig1 or Lrig3 fails to promote Ret-mediated axonal growth, haploinsufficiency of Lrig1 in Lrig3 mutants significantly potentiates Ret signaling and axonal growth of DRG neurons in response to GDNF ligands. We observe that Lrig1 and Lrig3 act redundantly to ensure proper cutaneous innervation of nonpeptidergic axons and behavioral sensitivity to cold, which correlates with a significant increase in the expression of the cold-responsive channel TrpA1. Together, our findings provide insights into the in vivo functions through which Lrig genes control morphology, connectivity and function in sensory neurons.

RESUMEN

Genetic kidney disease is common but often unrecognized. It accounts for most cystic kidney diseases and tubulopathies, many forms of congenital abnormalities of the kidney and urinary tract (CAKUT), and some glomerulopathies. Genetic kidney disease is typically suspected where the disease usually has a genetic basis or there is another affected family member, a young age at onset, or extrarenal involvement, but there are also many exceptions to these "rules". Genetic testing requires the patient's written informed consent. When a patient declines testing, another later conversation may be worthwhile. Genetic testing not only indicates the diagnosis but also the inheritance pattern, likely at-risk family members, disease in other organs, clinical course, and possibly effective treatments. Sometimes genetic testing does not identify a pathogenic variant even where other evidence is strong. A variant of uncertain significance (VUS) may be reported but should not be used for clinical decision making. It may be reclassified after more information becomes available without necessarily retesting the patient. Patients should be provided with a copy of their genetic test report, the results explained, and at-risk family members offered "cascade" testing. A referral to a clinical geneticist or genetic counselor helps identify affected family members and in providing advice to assist with reproductive decisions.

RESUMEN

BACKGROUND: Having a haematological condition can adversely affect the quality of life (QoL) of family members/partners of patients. It is important to measure this often ignored burden in order to implement appropriate supportive interventions. OBJECTIVE: To measure current impact of haematological conditions on the QoL of family members/partners of patients, using the Family Reported Outcome Measure-16 (FROM-16). METHODS: A cross-sectional study, recruited online through patient support groups, involved UK family members/partners of people with haematological conditions completing the FROM-16. RESULTS: 183 family members/partners (mean age = 60.5 years, SD = 13.2; females = 62.8%) of patients (mean age = 64.1, SD = 12.8; females = 46.4%) with 12 haematological conditions completed the FROM-16. The FROM-16 mean total score was 14.0 (SD = 7.2), meaning 'a moderate effect on QoL'. The mean FROM-16 scores of family members of people with multiple myeloma (mean = 15.8, SD = 6.3, n = 99) and other haematological malignancies (mean = 13.9, SD = 7.8, n = 29) were higher than of people with pernicious anaemia (mean = 10.7, SD = 7.5, n = 47) and other non-malignant conditions (mean = 11, SD = 7.4, n = 56, p < .01). Over one third (36.1%, n = 183) of family members experienced a 'very large effect' (FROM-16 score>16) on their quality of life. CONCLUSIONS: Haematological conditions, in particular those of malignant type, impact the QoL of family members/partners of patients. Healthcare professionals can now, using FROM-16, identify those most affected and should consider how to provide appropriate holistic support within routine practice.

RESUMEN

BACKGROUND: Severe trauma accounts for a main factor inducing mortality for individuals aged < 45 years in China, which requires admission to intensive care unit (ICU) to receive comprehensive treatment. Family members of patients with unanticipated and life-threatening trauma during their ICU stays often experience psychosocial distress due to illness uncertainty. Previous research has shown that family function and psychological resilience are associated with illness uncertainty, respectively. However, little is known about the current situation and interacting mechanism between family function, psychological resilience, and illness uncertainty of family members for ICU trauma patients. Therefore, this study focused on exploring the current situation and relationships between these three factors in family members for ICU trauma patients. METHODS: The convenience sampling approach was adopted in the present cross-sectional survey, which involved 230 family members for ICU trauma patients from 34 hospitals in Chongqing, China. Related data were extracted with self-reporting questionnaires, which included sociodemographic characteristic questionnaire, the Family Adaptability, Partnership, Growth, Affection and Resolve Scale (APGAR), the 10-item Connor-Davidson Resilience Scale (10-CD-RISC) and the Mishel's Illness Uncertainty Scale for Family Members (MUIS-FM). Pearson correlation analysis was conducted to examine the correlations between various variables. Additionally, a structural equation model was adopted to assess the mediating effect of psychological resilience on family function and illness uncertainty. RESULTS: According to our results, family members for ICU trauma patients experienced high illness uncertainty with moderate family dysfunction and low psychological resilience. Family function directly affected illness uncertainty and indirectly affected illness uncertainty through psychological resilience in family members of ICU trauma patients. CONCLUSIONS: Family function and psychological resilience are the protective factors for reducing illness uncertainty. Healthcare providers should take effective measures, including family-functioning improvement and resilience-focused interventions, for alleviating illness uncertainty in family members of ICU trauma patients.

RESUMEN

Synuclein family members (Snca, Sncb, and Scng) are expressed in the retina, but their precise locations and roles are poorly understood. We performed an extensive analysis of the single-cell transcriptome in healthy and injured retinas to investigate their expression patterns and roles. We observed the expression of all synuclein family members in retinal ganglion cells (RGCs), which remained consistent across species (human, mouse, and chicken). We unveiled differential expression of Snca across distinct clusters (highly expressed in most), while Sncb and Sncg displayed uniform expression across all clusters. Further, we observed a decreased expression in RGCs following traumatic axonal injury. However, the proportion of α-Syn-positive RGCs in all RGCs and α-Syn-positive intrinsically photosensitive retinal ganglion cells (ipRGCs) in all ipRGCs remained unaltered. Lastly, we identified changes in communication patterns preceding cell death, with particular significance in the pleiotrophin-nucleolin (Ptn-Ncl) and neural cell adhesion molecule signaling pathways, where communication differences were pronounced between cells with varying expression levels of Snca. Our study employs an innovative approach using scRNA-seq to characterize synuclein expression in health retinal cells, specifically focusing on RGC subtypes, advances our knowledge of retinal physiology and pathology.

RESUMEN

BACKGROUND: Caregivers' involvement in the diagnostic and monitoring processes of the level of consciousness of patients with Disorders of Consciousness (DoC) is strongly encouraged by international guidelines, as current literature suggests a better chance to detect behavioural responses when caregivers are involved in clinical assessments. Since caregivers' involvement during clinical assessments can be difficult, the Social And Family Evaluation (SAFE) scale has been recently proposed as a standardised tool that caregivers can autonomously use to collect their opinions about the level of consciousness of patients with DoC, based on the behaviours manifested by the patients in a given time-window. OBJECTIVE: Providing preliminary results concerning SAFE adoption. METHODS: 22 patients with DoC were assessed through the Coma Recovery Scale-revised (CRS-r), while their caregivers filled-in the SAFE. RESULTS: The SAFE showed a very high internal consistency, very high test-retest reliability, and high criterion validity when correlated to the CRS-r total score. Moreover, in line with the literature, the SAFE allowed the detection of some behaviours indicative of a higher level of consciousness than those detected by clinicians through the CRS-r in more than half of the sample. CONCLUSION: Overall, these preliminary data are promising for the adoption of the SAFE to collect the opinions of the caregivers about the level of consciousness of patients with DoC, especially in those settings where it would be otherwise difficult to monitor the patients, such as long-term care structures and at home, as a tool for telemedicine allowing the monitoring of patients in remote settings.

RESUMEN

BACKGROUND: Social support provided by a family member has been found to have a buffering effect on distress and is associated with better diabetes self-care. This study explores the meaning of social support, as described by close family members of foreign-born people living with type 2 diabetes (PWDM) in Sweden. It also explores the support provided by family members, and the support they need to be able to support the PWDM. METHODS: Qualitative explorative study, semi-structured interviews for data collection. Qualitative content analysis based on a theoretical framework on social support. Purposive sample of 13 family members, 18-52-years-old, born in countries in the Middle East, Africa, and Russia. RESULTS: The meaning of support was described as social and emotional. Most participants described a stressful situation; feelings of sadness/worry about the risk of the PWDM developing complications added to a strained life situation from which one could not opt out. Frequent daily contacts in a family network were evident, particularly by children trained as healthcare professionals. Caring for a family member was considered a filial piety, but it was also a chance to reciprocate. The support provided was mainly informational (e.g., reminders about nutritional intake), but it was also instrumental/practical (administering medicines, helping with economy/logistics, planning/cooking meals, basic care) and emotional (sharing meals, thoughts, and activities). The support the family members needed was getting first-hand information by attending the physician visits, being able to book appointments themselves at suitable times, and preventing the withholding of important information about the PWDM. They also desired an open telephone-line, oral and written information, particularly on diet. CONCLUSIONS: To family-members, supporting the PWDM was normal and a filial piety. Support provided and needed was not only informational but also instrumental/practical and emotional. In diabetes care, addressing foreign-born individuals, diabetes education needs to be developed, also including family members. Informational material, particularly on diet, and improved access to healthcare and information about the healthcare system have the potential to increase family members' control over the situation and prevent a negative trajectory in caregiving with perceived demands causing high levels of stress.

RESUMEN

BACKGROUND: Losing a close other to cancer is an incisive experience that occurs after a long course of illness and intense family caregiving. Despite an evident need for family engagement and support and guidance on this, patients and family members may not receive the attention and support they need when a family unit is experiencing a disruption by death. A clear understanding of the quality of care that is currently provided and its ability to address family needs is necessary to improve end-of-life and bereavement support to families affected by cancer. The purpose of this study is to investigate the quality of support of end-of-life and bereavement care to families, their (un)met needs, grief experiences, and self-perceived health outcomes. METHODS: A multi-center, cross-sectional observational survey study with family members (n = 35) whose close other died of cancer in a health institution or their own home in German-speaking Switzerland. RESULTS: Bereaved family members were mostly satisfied with end-of-life care. Information on the grief process and services, and acknowledgment of their grief was experienced as helpful. Most coped with their grief drawing on family resources and exhibited resilience, but they reported unmet needs in relation to family togetherness and caregiving. CONCLUSION: This study with a small number of family members indicates that support provided to families across settings and illness trajectories is perceived as helpful, with specific needs related to family support. The findings suggest that improvements should focus on ensuring care that addresses the family as a unit and enables togetherness, mutual reflection, meaningful relationships, preparedness for death, resilience, and benefit-finding.

RESUMEN

Variants of uncertain significance (VUS) are commonly identified in genetic testing. The rate at which a VUS is reclassified depends on multiple factors. However, as the amount of time it might take for a VUS to be reclassified varies, some patients with a VUS genetic testing result might have passed away before the VUS is reclassified. A VUS that is reclassified after the patient's death has clinical implications for the deceased patient's family members. The disclosure of reclassified VUS results for a deceased patient has complex legal and ethical implications. There are no established guidelines on how the reclassified VUS result for a deceased patient should be disclosed to at-risk relatives. An online survey was sent to members of the National Society of Genetic Counselors (NSGCs) to elicit practices and opinions regarding this issue. A total of 153 (4%) NSGC members completed the survey. Thirty-seven (24.2%) respondents reported having received a reclassified VUS for a deceased patient. Respondents were more likely to attempt disclosure if the variant was reclassified as pathogenic (93.5%) versus benign (76.5%), although the difference did not reach statistical significance (p = 0.06). Respondents more often reported the impact on family members (85.5%) than the decedent's right to privacy (15.0%) as extremely important when considering disclosure to family members. A legal mechanism to allow disclosure to relatives was supported by 70.6% of respondents and 97.4% felt the issue was important enough to pursue if such a process was in place. Only 9.8% of respondents supported a legal requirement of consent before disclosing to family members when a VUS is reclassified after the patient has passed away. Our results indicate that there is no consensus for how these results should be handled and a mechanism for disclosure of reclassified results to family members is supported.

RESUMEN

Formation of the vertebrate heart with its complex arterial and venous connections is critically dependent on patterning of the left-right axis during early embryonic development. Abnormalities in left-right patterning can lead to a variety of complex life-threatening congenital heart defects. A highly conserved pathway responsible for left-right axis specification has been uncovered. This pathway involves initial asymmetric activation of a nodal signaling cascade at the embryonic node, followed by its propagation to the left lateral plate mesoderm and activation of left-sided expression of the Pitx2 transcription factor specifying visceral organ asymmetry. Intriguingly, recent work suggests that cardiac laterality is encoded by intrinsic cell and tissue chirality independent of Nodal signaling. Thus, Nodal signaling may be superimposed on this intrinsic chirality, providing additional instructive cues to pattern cardiac situs. The impact of intrinsic chirality and the perturbation of left-right patterning on myofiber organization and cardiac function warrants further investigation. We summarize recent insights gained from studies in animal models and also some human clinical studies in a brief overview of the complex processes regulating cardiac asymmetry and their impact on cardiac function and the pathogenesis of congenital heart defects.

RESUMEN

BACKGROUND: The COVID-19 pandemic led to an intensified fear and threat of dying, combined with dying and grieving in isolation, in turn significantly impacting nursing in end-of-life situations. The study aims (1) to understand the lived experiences of nurses who provided care to end-of-life patients during COVID-19; and (2) to explore whether providing care under such circumstances altered the perspectives of these nurses regarding end-of-life care. METHODS: Applying the phenomenological-interpretive qualitative approach, 34 in-depth semi-structured interviews were conducted between March 2020-May 2021 with nurses from eight hospitals in Israel who were recruited through purposive and snowball sampling. Thematic analysis was applied to identify major themes from the interviews. RESULTS: Five main themes emerged from the analysis, including: (1) a different death; (2) difficulties in caring for the body after death; (3) the need for family at end-of-life; (4) weaker enforcement of advance care directives; and (5) prolonging the dying process. DISCUSSION: During the pandemic, nurses encountered numerous cases of death and dying, while facing ethical and professional issues regarding end-of-life care. They were required to administer more aggressive care than usual and even necessary, leading to their increased moral distress. The nurses' ethical concerns were also triggered by the requirement to wrap the corpse in black garbage-like bags to prevent contagion, which they felt was abusing the dead. The findings also demonstrate how family presence at end-of-life is important for the nursing staff as well as the patient. Finally, end-of-life situations during the pandemic in Israel were managed in an individual and personal manner, rather than as a collective mission, as seen in other countries. CONCLUSIONS: The study offers insights into the nurses' attitudes towards death, dying, and end-of-life care. An emphasis should be placed on the key elements that emerged in this study, to assist nurses in overcoming these difficulties during and after medical crises, to enhance end-of-life care and professionalism and decrease burnout.

RESUMEN

BACKGROUND: Retrospecting the trust gaps and their dynamics during the pandemic is crucial for understanding the root causes of postpandemic challenges and offers valuable insights into preparing for future public health emergencies. The COVID-19 pandemic eroded people's trust in strangers and acquaintances, while their trust in family members remained relatively stable. This resulted in 2 trust gaps, namely, the family members-strangers trust gap and the family members-acquaintances trust gap. Widening trust gaps impede social integration and undermine the effective management of public health crises. However, little is known about how digital media use shaped trust gaps during a pandemic. OBJECTIVE: This study aims to investigate the relationships between digital media use, negative emotions, the family members-strangers trust gap, and the family members-acquaintances trust gap during the COVID-19 pandemic in China. We test the mediating role of negative emotions between digital media use and 2 trust gaps and compare the indirect effect of digital media use on 2 trust gaps through negative emotions. METHODS: A cross-sectional web-based survey was conducted in China between January 31, 2020, and February 9, 2020. A total of 1568 adults participated in the survey. Questions related to digital media use, negative emotions, trust in family members, trust in acquaintances, and trust in strangers during the pandemic were asked. Regression analyses were performed to test the associations between the examined variables. We used a 95% bootstrap CI approach to estimate the mediation effects. RESULTS: Digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), which in turn were positively associated with the family members-strangers trust gap (B=0.15, SE 0.03; P<.001). Likewise, digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), while negative emotions were positively associated with the family members-acquaintances trust gap (B=0.08, SE 0.03; P=.01). Moreover, the indirect effect of digital media use on the family members-strangers trust gap (B=0.03, SE 0.01; 95% CI 0.01-0.04) was stronger than that on the family members-acquaintances trust gap (B=0.01, SE 0.01; 95% CI 0.003-0.027). CONCLUSIONS: The results demonstrate that negative emotions resulting from the frequent use of digital media are a key factor that accounts for the widening trust gaps. Considering the increasing reliance on digital media, the findings indicate that the appropriate use of digital media can prevent the overamplification of negative emotions and curb the enlargement of trust gaps. This may help restore social trust and prepare for future public health crises in the postpandemic era.

RESUMEN

BACKGROUND: Utilization of video calls on hospital wards to facilitate involvement of and communication with family members is still limited. A deeper understanding of the needs and expectations of family members regarding video calls on hospital wards is necessary, to identify potential barriers and facilitate video calls in practice. AIM: The aim of this study was to explore the views, expectations and needs of a patient's family members regarding the use of video calls between family members, patients and healthcare professionals, during the patient's hospital admission. METHODS: A qualitative study was carried out. Semi-structured interviews with family members of patients admitted to two hospitals were conducted between February and May 2022. Family members of patients admitted to the surgical, internal medicine and gynaecological wards were recruited. RESULTS: Twelve family members of patients participated. Family members stated that they perceive video calls as a supplemental option and prefer live visits during hospital admission. They expected video calls to initiate additional moments of contact with healthcare professionals, e.g. to join in medical rounds. When deploying video calls, family members mentioned that adequate instruction and technical support by nurses should be available. CONCLUSION: Family members considered video calls valuable when visiting is not possible or to participate in medical rounds or other contacts with healthcare professionals outside of visiting hours. IMPLICATIONS: Family members need to be supported in options and use of video calls on hospital wards. Additional knowledge about actual participation in care through video calls is needed as well as the effect on patient, family and healthcare professional outcomes. IMPACT: Using video calls on hospital wards can provide family members with flexible alternatives for contact and promote family involvement. REPORTING METHOD: COREQ guidelines. PATIENT OR PUBLIC CONTRIBUTION: Family members of patients admitted to hospital have contributed by sharing their perspectives in interviews. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: Family members perceive additional value from the use of video calls on hospital wards. For family, use of video calls needs to be facilitated with clear instruction materials and support. TRIAL AND PROTOCOL REGISTRATION: Amsterdam UMC Medical Ethics Review Committee (ref number W21_508 # 21.560).

RESUMEN

AIM: To describe the variations of family members' conceptions of their supportive care needs (SCN) across the colorectal cancer (CRC) trajectory. DESIGN: A descriptive qualitative study with a phenomenographic approach. METHOD: Individual semi-structured interviews were conducted from May 2022 to October 2022 with 23 family members of persons diagnosed with colorectal cancer. The interviews were analysed using phenomenographic analysis following the Consolidated criteria for reporting qualitative research (COREQ) checklist. RESULTS: The phenomenographic analysis resulted in five categories. Not of importance describes family members' needs as unimportant due to the good prognosis and the organization of care and in relation to the needs of others. Only satisfiable by professionals describes information possessed by the healthcare professionals as key, as well as the need for professional counselling for the family members to process their emotions. Managed by themselves describes family members preferring to manage their SCN themselves by turning to the appropriate social support and/or by using coping skills. Understood retrospectively describes SCN as only understandable when things have calmed down and as requiring one's own experience to understand. Left unmet describes SCN as unnoticed by the healthcare professionals or not brought to light by the family members, or family members not knowing where to turn for support. CONCLUSION: Supportive care should involve individualized information, proactive and repeated assessments of needs across the trajectory, as well as encouragement of family members to reflect on their needs and to accept support when needed. IMPACT: There is a gap in the literature regarding family members' SCN across the CRC trajectory which this study addresses. Findings show five categories of family members' conceptions of their SCN. Those findings could serve as a basis for the development of clinical colorectal supportive care across the cancer trajectory. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Findings show that to offer family members of persons diagnosed with colorectal cancer support only at the time of diagnosis is insufficient. Instead, the healthcare team is recommended to proactively and repeatedly try to identify those in need and the characteristics of their needs. In addition, it is important to offer individualized information and strive to encourage family members to reflect on their situation and to not suppress their own needs if emerging. REPORTING METHOD: Reporting adheres to the consolidated criteria for reporting qualitative research (COREQ) checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMEN

AIM: To investigate the perceptions of family members (FMs) of patients with traumatic brain injury (TBI) and nurses on empowering support and its implementation during the acute phase within Finnish neurosurgical and neurological care in hospital settings, focusing on identifying similarities and differences in their viewpoints. DESIGN: Participatory qualitative descriptive study. METHODS: Data were collected from seven FMs and 11 nurses using the World Café method in November 2019. An abductive approach was employed for data analysis, combining deductive interpretation within the conceptual framework of empowering support and inductive content analysis. RESULTS: Four main themes were identified: (1) FMs' diverse information and guidance needs of TBI, treatment and its impact on family life, (2) support based on empowering FMs in participation, competence and decision-making, (3) empowering FMs through collaborative nursing practices and interprofessional support, and (4) internal and external hospital support enhancing and promoting the empowerment of FMs. CONCLUSION: The perceptions of FMs and nurses regarding empowering support were largely consistent, yet diverged in its implementation in nursing practice. Nurses play a crucial role in fostering the empowerment of FMs; however, further research is needed to explore the impact of organisational and community factors on the implementation of empowering support. IMPACT: Our study contributes to advancing nursing practices by underscoring the necessity for a paradigm shift towards a family-centred approach. Furthermore, it emphasises the urgency for standardising nursing practices to ensure equitable access to empowering support for FMs, applicable across various care settings for patients with TBI. PUBLIC CONTRIBUTION: This review is part of a larger research project in which FMs of patients with TBI and nurses were involved in designing the project. REPORTING METHOD: This study was reported using the Consolidated Criteria for Reporting Qualitative Checklist for qualitative studies.

RESUMEN

While previous research explored the utilization of culturally supportive resources in multiethnic communities, there is a paucity of information regarding culturally relevant resources for Black Canadian family members. The study explored Black family members' experiences and interpretations regarding access to culturally supportive resources for family members and their relatives who suffer from substance use disorders. Black family members are defined as African Canadians, Caribbean Canadians, or Caribbean Blacks. A focused ethnography was conducted with a purposive sample of 26 Black family members in Ontario, Canada. The interviews were conducted from June to September 2021. Seventeen participants originated from parts of Africa, and nine were from different parts of the Caribbean. The participants comprised mothers (n = 5), fathers (n = 2), step-fathers (n = 1), husbands (n = 1), wives (n = 2), uncles (n = 5), aunties (n = 2), siblings (n = 5), in-laws (n = 2), and guardians (n = 1). Leininger's four Phases of Ethnonursing Qualitative Data Analysis were used for data analysis. Three themes were generated: (1) Navigating Existing Options and Resources for Families and Their Relatives; (2) Drawing upon Religion and Spirituality as Perceived Resources; and (3) Call for Culturally Relevant Programs for Substance Use Disorders Harm Reduction. Participants described experiencing a lack of culturally relevant resources and subsequently opting to navigate other resources. One such option was to send their relatives back to their country of origin to access cultural rehabilitation treatment options. There is a significant need for guidelines and policies regarding creating timely access to culturally relevant resources in Canada that support families and their relatives towards harm reduction and recovery outcomes.

RESUMEN

The present study examined whether there were ethnoracial differences in the use of formal and informal resources by family members of individuals in the early stages of psychosis. A sample of 154 family member respondents participated in an online cross-sectional survey. Ethnoracially minoritized family members disproportionately made early contact with informal resources (e.g., religious/spiritual leaders, friends, online support groups) on the pathway to care compared to non-Hispanic white family members who tended to contact formal resources (primary care doctors/nurses or school counselors). A description of early contact among Black and Hispanic family members are also described. Study findings highlight that ethnoracially minoritized families seek out support and/or resources from informal resources embedded within their community. Our findings suggest the need for targeted strategies that leverage the reach of informal settings to capture family members as well as general community members.
