Cocreating Meaning Through Expressive Writing and Reading for Cancer Caregivers.

PURPOSE: Caregivers of patients with cancer cope with socioemotional challenges, which can adversely affect their well-being. We developed an intervention, expressive writing and reading (EWR), to promote emotional processing and social connectedness among caregivers. In a single-arm pilot study, we assessed its feasibility and perceived usefulness. METHODS: Caregivers participated in weekly 1.5-hour EWR workshops offered over 20 weeks. After 4 sessions, they completed semistructured interviews, which were analyzed using qualitative descriptive analysis. FINDINGS: Of 65 caregivers approached, 25 were eligible, 18 consented, and 9 (50%) caregivers completed at least 4 workshops and the interview. Their responses revealed 3 themes: "inner processing," "interpersonal learning," and "enhanced processing and preparedness." Perceived benefits of EWR included emotional and cognitive processing (individual and collaborative), learning from the emotions and experiences of other caregivers, and preparing for upcoming challenges. CONCLUSIONS: Expressive writing and reading can be a safe and cost-effective supportive intervention for caregivers of patients with cancer.

Malignant hyperthermia and the clinical significance of type-1 ryanodine receptor gene (RYR1) variants: proceedings of the 2013 MHAUS Scientific Conference.

The Malignant Hyperthermia Association of the United States and the Department of Anesthesia at the University of Toronto sponsored a Scientific Conference on November 1-2, 2013 in Toronto, ON, Canada. The multidisciplinary group of experts, including clinicians, geneticists, and physiologists involved in research related to malignant hyperthermia (MH), shared new insights into the pathophysiology of diseases linked to the type-1 ryanodine receptor gene (RYR1) as well as the relationship between MH and "awake MH" conditions, such as exertional rhabdomyolysis and exertional heat illness. In addition, the molecular genetics of MH and clinical issues related to the diagnosis and management of disorders linked to RYR1 were presented. The conference also honoured Dr. David H. MacLennan for his contributions to our understanding of the genetics, pathogenesis, and treatment of MH and other RYR1-related myopathies. This report represents a summary of the proceedings of this conference.

Confirmation that the renin gene distal enhancer polymorphism REN-5312C/T is associated with increased blood pressure.

BACKGROUND: Studies of knockout and transgenic mice have demonstrated key roles for genes encoding components of the renin angiotensin system in blood pressure regulation. However, whether polymorphisms in these genes contribute to the cause of essential hypertension in humans is still a matter of debate. METHODS AND RESULTS: We performed an experiment with dense tagging single-nucleotide polymorphism coverage of 4 genes encoding proteins that control the overall activity of the cascade, namely renin, angiotensinogen, angiotensin-converting enzyme, and angiotensin-converting enzyme 2, in 2 Irish populations. Both clinic and 24-hour ambulatory blood pressure measurements were available from population I (n=387), whereas just clinic blood pressure was measured in population II (n=1024). Of the 23 polymorphisms genotyped, only a single renin gene polymorphism, REN-5312C/T, showed consistent statistically significant associations with elevated diastolic pressures. Carriage of one REN-5312T allele was associated with the following age- and sex-adjusted increments in diastolic pressures (mean [95% CI]): population I, clinic, 1.5 mm Hg (0.3 to 2.8); daytime, 1.4 mm Hg (0.4 to 2.4); night-time, 1.3 mm Hg (0.4 to 2.3), and population II, clinic, 1.1 mm Hg (0.1 to 2.1). Haplotypic analyses and multivariate stepwise regression analyses were in concordance with individual single-nucleotide polymorphism analyses. CONCLUSIONS: The REN-5312T allele had been shown previously to result in increased in vitro expression of the renin gene. We have now shown, in 2 independent populations, that carriage of a REN-5312T allele is associated with elevated diastolic blood pressure. These data provide evidence that renin is an important susceptibility gene for arterial hypertension in whites.
