Myocardial Injury in Noncardiac Surgery in Sweden

The purpose of this multicentre, prospective, observational study is to identify robust biochemical markers that predict adverse cardiovascular outcomes and mortality in patients undergoing major abdominal surgery.

FIND Stroke Recovery - A Longitudinal Study

Stroke survivors frequently suffer disabilities including motor and cognitive problems, impairments in speech and vision, depression, and several other disabilities that worsen their quality of life. Some will recover fully after stroke and others will have permanent impairments. Few studies show trajectories of recovery in different domains after stroke, hence recovery time-lines are not fully known. Also, the whole range of mechanisms leading to recovery are not precisely known (1). To monitor those mechanisms one can utilize biomarkers. In parallel to the studies of recovery, studies on time series of biomarkers after stroke are limited (2). Hence, a crucial first step to increase knowledge on biomarkers of stroke recovery is to gain a better understanding of the time course of both stroke recovery and biomarker patterns. Biomarkers can later be used for outcome predictions after stroke.

Individual Factors Related to Chronic Low-grade Inflammation and Cardiometabolic Disease Risk

The goal of this observational study is to learn about low-grade inflammation in healthy individuals and individuals with overweight or obesity. The main questions it aims to answer are: * Whether it is possible to predict low-grade inflammation * What are the medical, biological, and lifestyle variables related to low-grade inflammation? Participants will be asked to: 1. Attend a general medical visit to collect vital signs, anthropometric measurements, and collect blood samples. 2. Complete questionnaires and collect a stool sample at home.

Prospective Urban Rural Epidemiology Study

To examine the impact of health determinants at the individual (e.g. health related behaviors) and societal level (e.g. environmental factors, health related policy, quality of health systems) on health outcomes (e.g. death, non-communicable disease development) across a range of socioeconomic and health resource settings. Additional components of this study will examine genetic factors for non-communicable diseases. This will be examined both through a cross sectional component, and prospectively (cohort component).

Preventing Cognitive Decline: The CITA GO-ON Multi-domain Intervention Study

The GOIZ ZAINDU Gipuzkoa - GO - ON Study is an intervention trial to evaluate the efficacy of dementia prevention strategies in cognitively frail people. It is a large-scale randomized controlled trial in over 1000 older adults between 60 and 85 years old with increased CAIDE risk score (≥6), non-demented but with low performance in at least one of three brief cognitive tests. Participants will be randomized to receive standard health advice (SHA-control) or a multidomain intervention (MM-Int) consisting of 1) Risk factor control (vascular factors, polypharmacy); 2) Cognitive training, 3) Physical activity, 4) Dietary changing program, and 5) emotional counseling and social engagement. The primary aim is to demonstrate a 20% reduction in the proportion of subjects who decline in their NTB performance (z score) after 24 months in the intervention group compared to the controls. Secondary aims include: 1) Analyze cost-effectiveness; 2) Show a beneficial effect of the intervention on functional abilities, quality of life, and depressive and anxiety symptoms; 3) Investigate the impact of a lifestyle intervention on aging. In this sense, biological samples and neuroimaging studies will be collected to allow exploratory investigations on aging mechanisms, amyloid imbalance, tau pathology, epigenetics, neuroinflammation, vascular dysfunction, lipid dysregulation, white matter disintegration, cognitive and brain reserve. This protocol is participant-centered, empowering citizens since the recruitment process to gain access to knowledge about their dementia risk status via web or by phone and then decide to participate. Intervention activities have also taken into account participants' perspective with the design of easy-to-use and appealing activities (e.g., using a self-administered at-home physical activity program such as VIVIFRAIL© and EXERCITA© cognitive training materials that have been developed, taking into account the Basque Country population's cultural, linguistic and educational particularities; and diet and nutritional workshops with famous chefs to learn innovative and attractive healthy recipes). The GO-ON trial may shed light on the tools that people need to fulfill the expectation of an active, healthy dementia-free aging. These include digital tools that in the COVID19 pandemic have shown to be effective in removing distance barriers. GO-ON uses them to give support and expand the possibilities to clinical assessment settings and intervention delivery. The digital part of the intervention may expand preventive actions to small rural areas, including digital socialization. GO-ON Study, which starts in summer 2021, is the first large-scale lifestyle intervention trial in Southern Europe that takes part in the WORLDWIDE FINGERs network and will help answer whether the FINGER results can be replicated. The intervention design has been made on the basis that if proven to be efficacious, it may be easily applied at a Public System-level to guarantee a rapid and easy translation of research results to Primary Care settings and people homes.

It is a Prospective Study Aiming to Identify Incidence and Prevalence of Cardiovascular Diseases, Changes in Physical Activity, Dietary Habits and Anxiety Depression Levels Through a Period of Time in the Naval Personnel (PrOspeCtive HEllenic NAval PersoNnel StUdy in CardiovaScular Diseases)

Prospective study. Starting from 2014 all newly appointed 1st year cadets in Naval Academies will be enrolled until the class of 2025. Physical examination, food frequency questionnaire, physical activity questionnaire, anxiety/depression questionnaire, medical history will be filled out at first interview. Specific blood tests will be performed. Every participant will be interviewed every three years and will complete the same questionnaires. Follow up period is determined ten years after last class enrollment

Risk Evaluation and Management in Heart Failure

This is an prospective study conducted in a Chinese heart failure population. The study investigates the effects of cardiovascular disease risk factors such as lifestyle behaviors,biomarkers and intermediate diseases on heart failure prognosis.
