Study of mutual influence between trait anxiety and risk of depression among older couples facing cancer.

INTRODUCTION: The present study aims to examine the process of mutual influence in older couples with cancer diagnosis by studying their risk of depression. MATERIALS AND METHODS: 282 couples with one spouse diagnosed with cancer were selected from the Three-City cohort study. Dyadic analyses were used to determine whether trait anxiety affects the risk of depression and whether a mutual influence process occurs prior and post cancer diagnosis. Cross-sectional analyses were performed at two time-points: before and after receiving the diagnosis. RESULTS: A higher level of anxiety among cancer patients resulted in a decreased risk of depression among spousal caregivers. Moreover, a higher anxiety among spousal caregivers increased their own risk of depression, but it didn't influence depression risk among cancer patients. While there is an intra-individual relationship between a higher level of trait anxiety and a greater risk of depression prior to cancer diagnosis, there is no cross-influence between spouses. DISCUSSION: The study findings indicate that a dyadic psychological adjustment process might help older adults to cope with cancer by limiting the risk of depression among spousal caregivers.

Immune thrombotic thrombocytopenic purpura in older patients: prognosis and long-term survival.

Older age is associated with increased mortality in immune thrombotic thrombocytopenic purpura (iTTP). Yet, data are scarce regarding iTTP occurring among older patients. To assess clinical features and long-term impact of iTTP on mortality in older patients (>60 years old), characteristics and prognoses of adult iTTP patients enrolled in the French Reference Center for Thrombotic Microangiopathies registry between 2000 and 2016 were described according to age (<60 years old or ≥60 years old). Long-term mortality of iTTP older survivors was compared with that of non-iTTP geriatric subjects. Comparing, respectively, older iTTP patients (N = 71) with younger patients (N = 340), time from hospital admission to diagnosis was longer (P < .0001); at diagnosis, delirium (P = .034), behavior impairment (P = .045), renal involvement (P < .0001), and elevated troponin level (P = .025) were more important whereas cytopenias were less profound (platelet count, 22 × 103/mm3 [9-57] vs 13 × 103/mm3 [9-21], respectively [P = .002]; hemoglobin level, 9 g/dL [8-11] vs 8 g/dL [7-10], respectively [P = .0007]). Short- and mid-term mortalities were higher (P < .0001) and increased for every 10 years of age range. Age ≥60 years, cardiac involvement, increased plasma creatinine level, and total plasma exchange volume were independently associated with 1-month mortality. Compared with a non-iTTP geriatric population, older survivors showed an increased long-term mortality (hazard ratio = 3.44; P < .001). In conclusion, older iTTP patients have atypical neurological presentation delaying the diagnosis. Age negatively impacts short-term but also long-term mortality.
