RESUMEN
OBJECTIVE: The aim of the present study was to investigate the effects of a lifestyle intervention on cardiometabolic risk factors in patients with systemic lupus erythematosus with a high cardiovascular risk profile. METHODS: This trial was conducted in Sao Paulo, Brazil between August 2020 and March 2023. The patients were randomly assigned to lifestyle intervention or control. The intervention was a 6-month multifaced program focused on behavioral changes through personalized recommendations for increasing physical activity (structured and non-structured) and improving eating aspects. Cardiometabolic risk score (primary outcome), anthropometry and visceral fat, aerobic capacity, blood pressure, inflammatory and oxidative stress markers, and blood flow and endothelial function were assessed before and after the intervention. RESULTS: A total of 80 patients were randomized. Twelve and 6 patients dropped out due to personal reasons in the intervention and control groups, respectively. Average adherence rate for the intervention was 56.9%. Intention-to-treat analysis showed no significant difference between groups in the cardiometabolic risk score (intervention group - Pre: 1.7 ± 3.6; Post: -1.6 ± 4.0; control group - Pre: -1.9 ± 3.6; Post: -2.0 ± 3.8; estimated mean difference between groups at post: -0.4; 95% confidence intervals: -2.7; 1.9; p = 0.96). This finding was confirmed by exploratory, per-protocol analysis. No significant differences were observed between adherents vs. non-adherent participants. Secondary outcomes did not change between groups. CONCLUSION: This 6-month, individualized, lifestyle intervention did not improve cardiovascular risk factors in SLE patients with a high cardiovascular risk profile. TRIAL REGISTRATION: clinicaltrials.gov (NCT04431167).

There is a paucity of studies assessing multidisciplinary interventions focused on tackling physical inactivity/sedentary behavior and poor dietary habits in SLE. The Living well with Lupus (LWWL) is a randomized controlled trial to investigate whether a six-month lifestyle change intervention will improve cardiometabolic risk factors (primary outcome) among systemic lupus erythematosus (SLE) patients with low disease activity (SLEDAI score ≤ 4) and with high cardiovascular risk. As secondary goals, we will evaluate: (1) the intervention's safety, efficacy, and feasibility in promoting lifestyle changes, and (2) the effects of the intervention on secondary outcomes (i.e., clinical parameters, functional capacity, fatigue, psychological aspects, sleep quality and health-related quality of life). Patients will be randomly allocated to either a control (i.e., standard care) or a lifestyle intervention group using a simple randomization (1:1 ratio, blocks of 20). Mixed Model analyses will be conducted for comparing groups following an intention-to-treat approach. A per protocol analysis will also be conducted. This study has the potential to generate new, clinically relevant data able to refine the multidisciplinary management of SLE patients. Protocol version number: NCT04431167 (first version).

BACKGROUND: Infrarenal abdominal aortic aneurysms (AAA) are responsible for high rates of rupture-associated morbidity and mortality and can be treated by open or endovascular surgery. OBJECTIVES: To analyze risk factors and survival associated with surgical and endovascular AAA treatment methods. METHODS: A retrospective, longitudinal study involving 41 patients who underwent endovascular or open AAA repair, whether elective or emergency, over a 48-month period, with analysis of preoperative comorbidities, 30-day and 1-year survival, in-hospital mortality, length of hospital stay, transfusion of blood products, duration of surgery, and development of acute kidney failure. Inferential statistics and survival analysis considered a 95% CI and p < 0.05 as significant. RESULTS: Twelve of the 41 patients were treated with open surgery and 29 with endovascular techniques. The majority were male (75%), with an average age of 71 (range: 56 - 90 years). There were no differences in demographic or risk factors between the groups. Overall survival rates for open and endovascular repair were different for both 30 days (37 vs. 72%, p = 0.01) and 360 days (37 vs. 67%, p = 0.01). However, survival rates in elective cases were similar at 30 days (71 vs. 76%, p = 0.44) and 360 days (both 71%, p = 0.34). Endovascular repair showed shorter length of hospital stay (3.0 vs. 4.4 days; p = 0.02) and duration of surgery (111 vs. 163 min; p < 0.01) compared to open repair. CONCLUSIONS: There was no difference in short- or medium-term survival of AAA patients treated electively with endovascular or open surgery. Hospital stays and duration of surgery were both shorter with minimally invasive treatment.
