Background: Dementia has a negative impact on the quality of life of the person with dementia and their spouse caregivers, as well as on the couple’s relationship, which can lead to high levels of distress for both partners. Hypnosis has been shown to be effective in managing distress and increasing the quality of the relationship. Objective: The aim was to develop a standardized hypnosis intervention for couples confronted with Alzheimer’s disease and evaluate its feasibility, acceptability, and helpfulness in managing the distress of both partners and increasing the quality of the relationship. Methods: In a single-arm study, sixteen couples received the 8-week intervention. Qualitative and quantitative assessments were conducted pre- and post-intervention as well as three months after. Results: 88.9% of couples (n = 16) of the final sample (n = 18) completed the intervention. Despite the negative representations of hypnosis, several factors led couples to accept to participate in this study: positive expectations, professional endorsement, medical application, non-drug approach, home-based, free, flexible, and couple-based intervention. The results showed a significant decrease in distress for both partners. These effects were maintained three months after the intervention. Couples felt more relaxed, had fewer negative emotions, accepted difficulties more easily, were more patient, and reported better communication and more affection in the relationship. Conclusion: Overall, this pilot study shows the feasibility and acceptability of hypnosis with couples confronted with Alzheimer’s disease. Although measures of the preliminary pre- and post-intervention effects are encouraging, confirmatory testing with a randomized controlled trial is needed.

We investigated serum neutralizing activity against BA.1 and BA.2 Omicron sublineages and T cell response before and 3 months after administration of the booster vaccine in healthcare workers (HCWs).HCWs aged 18-65 years who were vaccinated and received booster doses of the BNT162b2 vaccine were included. Anti-SARS coronavirus 2 IgG levels and cellular response (through interferon γ ELISpot assay) were evaluated in all participants, and neutralizing antibodies against Delta, BA.1, and BA.2 were evaluated in participants with at least one follow-up visit 1 or 3 months after the administration of the booster dose.Among 118 HCWs who received the booster dose, 102 and 84 participants attended the 1-month and 3-month visits, respectively. Before the booster vaccine dose, a low serum neutralizing activity against Delta, BA.1, and BA.2 was detectable in only 39/102 (38.2%), 8/102 (7.8%), and 12/102 (11.8%) participants, respectively. At 3 months, neutralizing antibodies against Delta, BA.1, and BA.2 were detected in 84/84 (100%), 79/84 (94%), and 77/84 (92%) participants, respectively. Geometric mean titres of neutralizing antibodies against BA.1 and BA.2 were 2.2-fold and 2.8-fold reduced compared with those for Delta. From 1 to 3 months after the administration of the booster dose, participants with a recent history of SARS coronavirus 2 infection (n = 21/84) had persistent levels of S1 reactive specific T cells and neutralizing antibodies against Delta and BA.2 and 2.2-fold increase in neutralizing antibodies against BA.1 (p 0.014). Conversely, neutralizing antibody titres against Delta (2.5-fold decrease, p 0.0001), BA.1 (1.5-fold, p 0.02), and BA.2 (2-fold, p 0.0001) declined from 1 to 3 months after the administration of the booster dose in individuals without any recent infection.The booster vaccine dose provided significant and similar response against BA.1 and BA.2 Omicron sublineages; however, the immune response declined in the absence of recent infection.

The successful design of musical interventions for dementia patients requires knowledge of how rhythmic abilities change with disease severity. In this study, we tested the impact of the severity of the neurocognitive disorders (NCD) on the socioemotional and motor responses to music in three groups of patients with Major NCD, Mild NCD, or No NCD. Patients were asked to tap to a metronomic or musical rhythm while facing a live musician or through a video. We recorded their emotional facial reactions and their sensorimotor synchronization (SMS) abilities. Patients with No NCD or Mild NCD expressed positive socioemotional reactions to music, but patients with Major NCD did not, indicating a decrease in the positive emotional impact of music at this stage of the disease. SMS to a metronome was less regular and less precise in patients with a Major NCD than in patients with No NCD or Mild NCD, which was not the case when tapping with music, particularly in the presence of a live musician, suggesting the relevance of live performance for patients with Major NCD. These findings suggest that the socioemotional and motor reactions to music are negatively affected by the progression of the NCD.
