Role of Pro-Resolving Lipid Mediators in Obesity-Associated Diseases

The main objective of this project is to determine the possible association between the levels of certain bioactive lipids, which the body produces from dietary fatty acids, and tumor characteristics in breast cancer patients, as well as their relationship with overweight/obesity. Specific objectives are: * To analyse anthropometric and body composition changes. * To evaluate physical activity level. * To determine dietary profile. * To determine the adherence to Mediterranean dietary pattern. * To assess the quality of life. * To determine levels of specialized pro-resolving lipid mediators The target sample size is 60 subjects. Participants will be allocated in four groups: * Group 1: Postmenopausal healthy women with overweight/obesity (n=15) * Group 2: Postmenopausal healthy women with normoweight (n=15) * Group 3: Postmenopausal women with breast cancer and overweight/obesity (n=15) * Group 4: Postmenopausal women with breast cancer and normoweight (n=15)

The IGNITE for Kids Study on Concentrated Investment in Black Neighborhoods and Child Health and Well-Being

Black children and adults in the United States fare worse across nearly every health indicator compared to White individuals. In Philadelphia, the location of this study, these health disparities result in a stark longevity gap, with average life expectancies in poor, predominantly Black neighborhoods being 20 years lower than in nearby affluent, predominantly White neighborhoods. The investigators will conduct a cluster randomized controlled trial (RCT) of a suite of place- based and financial-wellbeing interventions at the community, organization, and individual/household levels that address the social determinants of racial health disparities. At the community level, the investigators address underinvestment in Black neighborhoods by implementing vacant lot greening, abandoned house remediation, tree planting, and trash cleanup. At the organization level, the investigators partner with community-based financial empowerment providers to develop cross-organizational infrastructure to increase reach and maximize efficiency. At the individual/household levels, the investigators increase access to public benefits, financial counseling and tax preparation services, and emergency cash assistance. The investigators will test this "big push" intervention in 60 Black neighborhood micro-clusters, with a total of 480 children. The investigators hypothesize that this "big push" intervention will have significant impact on children's health and wellbeing.

A Phase I, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single Ascending Doses of SIM0811 Injection in Healthy Chinese Adult Subjects

This study plans to set up 5 dose groups across 7 cohorts, including intravenous bolus plus infusion administration as well as intravenous bolus alone. The study plans to enroll 8 subjects per cohort (investigational drug: placebo = 6:2), including both males and females, totaling 56 healthy subjects. The study begins with dose-escalation enrollment starting from Cohort 1. Each cohort receives a single dose, sequentially completing Cohorts 2, 3, 4, 5, 6, and 7. After each cohort's dosing is completed, a 7-day observation period is conducted for safety evaluation. If the termination criteria are not met, the study may proceed to the next dose level following assessment by the Safety Review Committee. By collecting adverse events, as well as abnormal indicators from vital signs, electrocardiograms, and laboratory tests, and collecting blood samples at planned time points to measure SIM0811 plasma concentration and thrombotic molecular markers, the study aims to evaluate the tolerability and safety of SIM0811 injection in Chinese healthy adult subjects, characterize its pharmacokinetic profile after single-dose administration, and explore the change curves of thrombotic molecular markers (plasmin-α2 antiplasmin complex PIC, fibrin degradation products FDP)

Florida Community-Engaged Research Alliance (FL-CEAL)

The purpose of the study is learn more about ways to help people with non-medical issues that can affect participant health. The study team will examine if Community Health Workers, members of a community who provide basic health and medical care within communities, are more helpful to people with non-medical issues than simple reading materials on how participants can do it themselves.

Gait Assessment Via Telephone Application

The evaluation of human gait is a crucial component of the clinical assessment and decision-making process. The gold standard in gait analysis is computerized gait analysis, which allows for three-dimensional digital data acquisition through computers (3D Computerized Gait Analysis). However, this technology is not readily accessible in routine analyses, as it proves to be a time-consuming and expensive endeavor in terms of infrastructure and human resources. The utilization of smartphones in clinical applications is on the rise, facilitated by the increasing accessibility of low-cost or free "applications," thereby addressing the limitations associated with traditional gait analysis methods. The Gait-Analyzer application is among the mentioned applications. However, in the literature, no evidence has been found regarding the validity and reliability of Gait-Analyzer application compared to the gold standard 3D computerized gait analysis systems within the context of gait analyses. The aim of this study is to comparatively examine the effectiveness of the Gait-Analyzer smartphone application with established 3D Computerized Gait Analysis systems, which have proven validity and reliability in gait analyses. Through this research, the study intends to elucidate the validity and reliability of spatiotemporal parameters of walking within the Gait-Analyzer smartphone application.

Ageing and Health. Spanish Longitudinal Study

Age with Health is a longitudinal cohort study aimed to examine trajectories of health, disability and wellbeing and their determinants for Spanish ageing population. The data that makes up the baseline was collected from a nationally representative sample of non-institutionalized adults as part of the "Collaborative Research on Aging in Europe (COURAGE in Europe)" project between July 2011 and May 2012. The second wave was carried out as part of the "Age with Health" project between December 2014 and June 2015, and three years later, in 2018, the third wave was carried out. In 2019-2021, a new cohort of participants were brought in (2019 cohort), some of whom were interviewed again by telephone during the first Coronavirus (COVID-19) lockdown, in early 2020. During 2022 a new evaluation of the participants of both cohorts (2011 and 2019) is expected.

The Effect of Aerobic and Anaerobic Exercise on Oxidative Stress and Cellular Fitness in Healthy Trained Young Men

This study aims to analyze the effects of aerobic and anaerobic exercise on health at the molecular level. By examining these effects, the study seeks to provide the public with insights into which types of exercise offer the most significant health benefits. Participants will engage in aerobic and anaerobic exercises for one month, with 5 mL of venous blood collected by experienced phlebotomists both before and after the exercise period. While blood collection may cause mild discomfort and temporary bruising, these symptoms should subside within a few days. The collected blood will be processed to separate plasma and leukocytes for the assessment of oxidative damage, lipid profile and cellular fitness parameters. The oxidative damage markers to be measured include malondialdehyde (MDA) levels, H2O2, and antioxidants such as total antioxidant capacity, superoxide dismutase, and glutathione peroxidase. Cellular fitness will be evaluated by measuring mitochondrial biogenesis markers (succinate dehydrogenase and PGC-1A), ATP levels, and ATPase inhibitor levels. The benefits for the participants, they will receive include a laboratory assessment to evaluate cell damage, lipid profiles, and mitochondrial function. Additionally, the study results will help identify the most beneficial type of physical exercise for optimal health.
