Well-Being Therapy and Lifestyle Intervention in Type 2 Diabetes: A Pilot Randomized Controlled Trial.

OBJECTIVE: This pilot randomized controlled trial evaluates the preliminary efficacy of a 4-month well-being therapy (WBT) and lifestyle intervention among adults with type 2 diabetes and overweight/obesity. METHODS: Fifty-eight patients were recruited from two outpatient clinics and randomized to receive the WBT-lifestyle intervention or the lifestyle intervention alone. Data were collected at baseline (T0), immediate postintervention (T1), 6-month follow-up (T2), and 12-month follow-up (T3). Primary efficacy outcomes included changes in weight, psychological distress, and well-being, whereas secondary efficacy outcomes included changes in lifestyle and physiological parameters. RESULTS: Compared with the lifestyle-alone intervention, the WBT-lifestyle intervention showed greater improvements in depression (p = .009, d = -0.6), hostility (p = .018, d = -0.6), and personal growth (p = .026, d = 0.5) at T1, in self-reported physical activity at T2 (p = .013, d = 0.7) and T3 (p = .040, d = 0.5), and in triglycerides (p = .019, d = -1.12) at T3. There were no differences between treatment groups in weight and other physiological parameters. CONCLUSIONS: These findings suggest that WBT may be a valuable addition to lifestyle interventions for improving short-term psychological outcomes and promoting long-term healthy changes in physical activity, with a potential impact on physiological outcomes.Trial Registration:ClinicalTrials.gov identifier: NCT03609463.

Oncolytic effect of SARS-CoV2 in a patient with NK lymphoma.

Covid-19 infection was a possible causal factor in the exhaustion and decrease number of NK clonal cells, resulting in a evident improvement of signs, symptoms and clinical features related to NK lymphoma refractory to previous immuno-chemiotherapy. It has been shown that SARS-CoV2 binds to ACE2. Covid-19 may infect NK cells to suppress their functions, as NK cells express angiotensin converting enzyme 2 (ACE2). The excessive production of proinflammatory cytokines in Covid-19 infection may have played a crucial role in lymphodepletion. Although not published in Covid-19, other RNA viruses that cause acute pulmonary infections promote NK cell apoptosis. In NK/T-cell lymphoma plasma EBV-DNA is a sensitive surrogate biomarker of lymphoma load. In this case, we also notice a dramatic transient reduction in plasmatic EBV-DNA viral copies during Covid-19 pneumonia other than NK clonal cells reduction, and after the infection resolution we described a lymphoma relapse as well as EBV-DNA increase and the rising in NK clonal cells count. Although the mechanism leading to spontaneous remission remain uncharacterized, we hypothezised that a favorable adaptive immunity against concurrent viral infection could render an enhanced anti-tumor effect. We suppose COVID-19 infection have induced a transient remission in this patient affected with NK neoplasm.
