Feasibility and acceptability of an integrated mind-body intervention for depression: whole-body hyperthermia (WBH) and cognitive behavioral therapy (CBT).

OBJECTIVE: To examine the feasibility of an integrated mind-body MDD treatment combining cognitive behavioral therapy (CBT) and whole-body hyperthermia (WBH). METHODS: In this single-arm trial, 16 adults with MDD initially received 8 weekly CBT sessions and 8 weekly WBH sessions. Outcomes included WBH sessions completed (primary), self-report depression assessments completed (secondary), and pre-post intervention changes in depression symptoms (secondary). We also explored changes in mood and cognitive processes and assessed changes in mood as predictors of overall treatment response. RESULTS: Thirteen participants (81.3%) completed ≥ 4 WBH sessions (primary outcome); midway through the trial, we reduced from 8 weekly to 4 bi-weekly WBH sessions to increase feasibility. The n = 12 participants who attended the final assessment visit completed 100% of administered self-report depression assessments; all enrolled participants (n = 16) completed 89% of these assessments. Among the n = 12 who attended the final assessment visit, the average pre-post-intervention BDI-II reduction was 15.8 points (95% CI: -22.0, -9.70), p = 0.0001, with 11 no longer meeting MDD criteria (secondary outcomes). Pre-post intervention improvements in negative automatic thinking, but not cognitive flexibility, achieved statistical significance. Improved mood from pre-post the initial WBH session predicted pre-post treatment BDI-II change (36.2%; rho = 0.60, p = 0.038); mood changes pre-post the first CBT session did not. LIMITATIONS: Small sample size and single-arm design limit generalizability. CONCLUSION: An integrated mind-body intervention comprising weekly CBT sessions and bi-weekly WBH sessions was feasible. Results warrant future larger controlled clinical trials.Clinivaltrials.gov Registration: NCT05708976.

Leukocyte telomere length in major depression: correlations with chronicity, inflammation and oxidative stress--preliminary findings.

BACKGROUND: Depression is associated with an unusually high rate of aging-related illnesses and early mortality. One aspect of "accelerated aging" in depression may be shortened leukocyte telomeres. When telomeres critically shorten, as often occurs with repeated mitoses or in response to oxidation and inflammation, cells may die. Indeed, leukocyte telomere shortening predicts early mortality and medical illnesses in non-depressed populations. We sought to determine if leukocyte telomeres are shortened in Major Depressive Disorder (MDD), whether this is a function of lifetime depression exposure and whether this is related to putative mediators, oxidation and inflammation. METHODOLOGY: Leukocyte telomere length was compared between 18 unmedicated MDD subjects and 17 controls and was correlated with lifetime depression chronicity and peripheral markers of oxidation (F2-isoprostane/Vitamin C ratio) and inflammation (IL-6). Analyses were controlled for age and sex. PRINCIPAL FINDINGS: The depressed group, as a whole, did not differ from the controls in telomere length. However, telomere length was significantly inversely correlated with lifetime depression exposure, even after controlling for age (p<0.05). Average telomere length in the depressed subjects who were above the median of lifetime depression exposure (≥9.2 years' cumulative duration) was 281 base pairs shorter than that in controls (p<0.05), corresponding to approximately seven years of "accelerated cell aging." Telomere length was inversely correlated with oxidative stress in the depressed subjects (p<0.01) and in the controls (p<0.05) and with inflammation in the depressed subjects (p<0.05). CONCLUSIONS: These preliminary data indicate that accelerated aging at the level of leukocyte telomeres is proportional to lifetime exposure to MDD. This might be related to cumulative exposure to oxidative stress and inflammation in MDD. This suggest that telomere shortening does not antedate depression and is not an intrinsic feature. Rather, telomere shortening may progress in proportion to lifetime depression exposure.

Extended-release bupropion for patients with major depressive disorder presenting with symptoms of reduced energy, pleasure, and interest: findings from a randomized, double-blind, placebo-controlled study.

OBJECTIVE: This multicenter, double-blind, placebo-controlled study evaluated the efficacy and safety of extended-release bupropion (bupropion XL) in the treatment of major depressive disorder (MDD) with prominent symptoms of decreased energy, pleasure, and interest. METHOD: Eligible adult outpatients meeting DSM-IV criteria for MDD were randomly assigned to bupropion XL 300 to 450 mg/day (N = 135) or placebo (N = 139) for 8 weeks. The primary efficacy measure, change from baseline on the 30-item Inventory of Depressive Symptomatology-Self Report (IDS-IVR-30) total score, was obtained using interactive voice response (IVR) technology. Secondary measures included change from baseline on the 30-item Inventory of Depressive Symptomatology-Clinician-Rated (IDS-C-30) total score and change in domain subset scores for energy, pleasure, and interest; for insomnia; and for anxiety. Response and remission rates were also calculated. Safety was assessed by withdrawal rates, adverse events (AEs), body weight, and vital signs. The study was conducted from June 24, 2003, to June 30, 2004. RESULTS: Bupropion XL was superior to placebo at endpoint in reducing the IDS-IVR-30 total score (p = .018) and the energy, pleasure, and interest domain (p = .007) and the insomnia domain (p = .023) scores. IDS-C-30 outcomes were also significant (p < .001; p < .001, and p = .008, respectively). Clinician-rated remission rates were significantly higher with bupropion XL than placebo (32% vs. 18%, IDS-C-30; 41% vs. 27%, IDS-IVR-30), as were response rates (50% vs. 35%, IDS-C-30; 53% vs. 38%, Clinical Global Impressions-Improvement of Illness). Most AEs were mild or moderate. The incidence of a >or= 7% body weight loss was 3.7% with bupropion XL and 1.4% with placebo. CONCLUSION: Bupropion XL was effective and well tolerated in MDD patients with decreased energy, pleasure, and interest.
