Effectiveness and Implementation Evaluation of NeoMayor for Improving Cardiovascular Health in Chilean Older Adults

This study aims to evaluate the effectiveness and implementation of NeoMayor, a mobile health (mHealth) intervention designed to improve cardiovascular health among older adults at elevated cardiovascular risk in Chile. NeoMayor is a smartphone-based application that provides personalized guidance on physical activity, diet, sleep, and mental well-being through a multidomain lifestyle approach. This multicenter randomized controlled trial will enroll community-dwelling older adults aged 55 to 75 years recruited from primary healthcare centers in urban and rural settings. Participants will be randomized in a 2:1 ratio to either the NeoMayor intervention or a control group receiving standard health information and usual care. The intervention duration will be four months. The primary objective is to determine whether NeoMayor improves cardiovascularhealth, measured with the Life's Essential 8 Cardiovascular Health Index (CVHI).Secondary objectives include changes in cognitive performance, depressivesymptoms, anxiety symptoms, quality of life, physical performance, and urinaryalbumin-to-creatinine ratio (UACR). This is a Hybrid Type 1 effectiveness-implementation trial. As an exploratory aim, participants in the NeoMayor arm are further randomized (2x2 factorial) to receivethe app with or without human health coach support, and with or without a wearable device, both used as implementation support strategies. The study will describe engagement, adherence, retention, and maintenance of app use over four months.This aim is hypothesis-generating; the trial is not powered to compare implementation strategies.

Quality of Life of Patients Who Have Undergone Bilateral Mastectomy

The investigators therefore aim to determine whether the type of mastectomy (preventive in a high-risk patient or therapeutic in a patient with a history of cancer), as well as the timing (immediate or delayed) and type of breast reconstruction, influence the quality of life and satisfaction of patients who have undergone bilateral mastectomy. The goal of this observational study is thus to measure and compare the quality of life of patients who have undergone bilateral mastectomy using the BREAST-Q questionnaire.
