A comparison of adult-child and spousal cancer caregivers' participation in medical decisions

Background Family caregivers often play a key role in medical decision-making for patients with cancer. Adult-children account for nearly half of caregivers, but often have less experience with serious illness care and decision-making and face unique relational challenges as the patient's child. Yet little research explores the potentially distinctive decision-making, involvement in decisions, and support needs of adult-child caregivers. Methods Analysis of survey data of U.S. cancer caregivers conducted by CancerCare® in 2021. Chisquare tests and multivariable regression models assessed whether adult-child and spousal caregivers differed on the type of medical decisions they participated in (e.g., treatment planning, medication management), who made the decision (e.g., caregiver or joint decision), and the resources that informed decisions (e.g., friends and family, education materials). Results Adult-children (N = 892) were less likely than spouses (N = 314) to participate in treatment planning (beta = -0.41; 95%CI = -0.81,-0.01), but more likely to be involved in decisions about whether to challenge medical authority (e.g., seeking alternative treatment, second opinion) (beta = 0.50; 95%CI = 0.22,0.78). Compared to spouses, adult-children made joint decisions with patients less often (-13.2-percentage points; 95%CI = -19.64,-6.67) and acted as primary decision-maker more frequently (5.60-percentage points; 95%CI = 0.01,10.43). More adult-children than spouses sought help and information regarding decisions from the oncology team (8.42-percentage points; 95%CI = 1.98,14.87) and friends and family (7.91-percentage points; 95%CI = 1.34,14.48). Conclusions How cancer caregivers and patients are related to each other shapes caregivers' medical decision-making. Adult-children's and spouses' probabilities of participating in and influencing decisions differed for certain types of decisions while adult-children were more likely to seek information and social support regarding decisions. These findings highlight the importance of the patient's and caregiver's relationship type in medical decision-making, suggesting that decision support programs may be more effective if they tailor programs by relationship type

Single amino acid deletion in transmembrane segment D4S6 of sodium channel Scn8a (Nav1.6) in a mouse mutant with a chronic movement disorder

International audienceMutations of the neuronal sodium channel gene SCN8A are associated with lethal movement disorders in the mouse and with human epileptic encephalopathy. We describe a spontaneous mouse mutation, Scn8a(9J), that is associated with a chronic movement disorder with early onset tremor and adult onset dystonia. Scn8a(9J) homozygotes have a shortened lifespan, with only 50% of mutants surviving beyond 6 months of age. The 3 bp in-frame deletion removes 1 of the 3 adjacent isoleucine residues in transmembrane segment DIVS6 of Nav1.6 (p.Ile1750del). The altered helical orientation of the transmembrane segment displaces pore-lining amino acids with important roles in channel activation and inactivation. The predicted impact on channel activity was confirmed by analysis of cerebellar Purkinje neurons from mutant mice, which lack spontaneous and induced repetitive firing. In a heterologous expression system, the activity of the mutant channel was below the threshold for detection. Observations of decreased nerve conduction velocity and impaired behavior in an open field are also consistent with reduced activity of Nav1.6. The Nav1.6Delta1750 protein is only partially glycosylated. The abundance of mutant Nav1.6 is reduced at nodes of Ranvier and is not detectable at the axon initial segment. Despite a severe reduction in channel activity, the lifespan and motor function of Scn8a(9J/9J) mice are significantly better than null mutants lacking channel protein. The clinical phenotype of this severe hypomorphic mutant expands the spectrum of Scn8a disease to include a recessively inherited, chronic and progressive movement disorde

Improving the Quality of Palliative Care through National and Regional Collaboration Efforts

BackgroundThe measurement and reporting of the quality of care in the field of palliation has become a required task for many health care leaders and specialists in palliative care. Such efforts are aided when organizations collaborate together to share lessons learned.MethodsThe authors reviewed examples of quality-improvement collaborations in palliative care to understand the similarities, differences, and future directions of quality measurement and improvement strategies in the discipline.ResultsThree examples were identified that showed areas of robust and growing quality-improvement collaboration in the field of palliative care: the Global Palliative Care Quality Alliance, Palliative Care Quality Network, and Project Educate, Nurture, Advise, Before Life Ends. These efforts exemplify how shared-improvement activities can inform improved practice for organizations participating in collaboration.ConclusionsNational and regional collaboratives can be used to enhance the quality of palliative care and are important efforts to standardize and improve the delivery of palliative care for persons with serious illness, along with their friends, family, and caregivers

Sarcopenia: its assessment, etiology, pathogenesis, consequences and future

Sarcopenia is a loss of muscle protein mass and loss of muscle function. It occurs with increasing age, being a major component in the development of frailty. Current knowledge on its assessment, etiology, pathogenesis, consequences and future perspectives are reported in the present review. On-going and future clinical trials on sarcopenia may radically change our preventive and therapeutic approaches of mobility disability in older peopleY. Rolland, S. Czerwinski, G.
