Slow-SPEED: Slowing Parkinson's Early Through Exercise Dosage
The goal of this clinical trial is two-fold. First to investigate the feasibility of whether a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in individuals with a LRRK2 G2019S or GBA1 N370S genetic mutation over a long period of time (24 months). Second, to explore the preliminary efficacy of exercise on markers for prodromal Parkinson's disease progression in individuals with a LRRK2 G2019S or GBA1 N370S genetic mutation. Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. A joint primary objective consists of two components. First to determine the longitudinal effect of an exercise intervention in LRRK2 G2019S or GBA1 N370S variant carriers on a prodromal load score, comprised of digital biomarkers of prodromal symptoms. The secondary component of the primary outcome is to determine the feasibility of a remote intervention study. The secondary objective is the effect of a physical activity intervention on digital markers of physical fitness. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD. Using these biomarkers, the investigators aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United Kingdom are currently in preparation (Slow-SPEED-UK) and active in the Netherlands (Slow-SPEED-NL). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups

Using the EHR to Advance Genomic Medicine Across a Diverse Health System
Given the expansion of indications for genetic testing and our understanding of conditions for which the results change medical management, it is imperative to consider novel ways to deliver care beyond the traditional genetic counseling visit, which are both amenable to large-scale implementation and sustainable. The investigators propose an entirely new approach for the implementation of genomic medicine, supported by the leadership of Penn Medicine, investigating the use of non-geneticist clinician and patient nudges in the delivery of genomic medicine through a pragmatic randomized clinical trial, addressing NHGRI priorities. Our application is highly conceptually and technically innovative, building upon expertise and infrastructure already in place. Innovative qualities of our proposal include: 1) Cutting edge EHR infrastructure already built to support genomic medicine (e.g., partnering with multiple commercial genetic testing laboratories for direct test ordering and results reporting in the EHR); 2) Automated EHR-based direct ordering or referring by specialist clinicians (i.e., use of replicable modules that enable specialist clinicians to order genetic testing through Epic Smartsets, including all needed components, such as populated gene lists, smartphrases, genetic testing, informational websites and acknowledgement e-forms for patient signature); 3) EHR algorithms for accurate patient identification (i.e., electronic phenotype algorithms to identify eligible patients, none of which currently have phenotype algorithms present in PheKB; 4) Behavioral economics-informed implementation science methods: This trial will be the first to evaluate implementation strategies informed by behavioral economics, directed at clinicians and/or patients, for increasing the use of genetic testing; further it will be the first study in this area to test two forms of defaults as a potential local adaptation to facilitate implementation (ordering vs. referring); and 5) Dissemination: In addition to standard dissemination modalities,PheKB95, GitHub and Epic Community Library, the investigators propose to disseminate via AnVIL (NHGRI's Genomic Data Science Analysis, Visualization, and Informatics Lab-Space). Our results will represent an entirely new paradigm for the provision of genomic medicine for patients in whom the results of genetic testing change medical management.

Parkinson Disease and DBS: Cognitive Effects in GBA Mutation Carriers
Every year, approximately 9,000 Parkinson disease (PD) patients undergo deep brain stimulator (DBS) placement into the subthalamic nucleus (STN-DBS). Studies suggest that PD patients with mutations in the glucocerebrosidase (GBA) gene are at high risk for cognitive impairment and approximately 10-17% of subjects undergoing DBS carry GBA mutations. There may be an interaction between STN-DBS, which also impairs cognitive function, and GBA, resulting in worsened cognitive function. This project will 1) determine the relationship between GBA mutation status and post-operative STN-DBS cognitive function, 2) broaden genotype-phenotype relationships of GBA mutation carriers and 3) provide scientific knowledge regarding the longitudinal cognitive effects of DBS in GBA mutation carriers through repeated neuropsychological testing.

GLUCOSE-MGH: Genetic Links Understood Through Challenge With Oral Semaglutide Exposure at MGH
The goal of this research study is to evaluate the pathophysiologic mechanisms by which genetic variation impacts response to an FDA-approved medication commonly used to treat type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological response to a mixed meal tolerance test (MMTT) before and after a 14-day treatment with oral semaglutide. The investigators will do this by measuring factors in the blood, such as sugars, fats, metabolites, and proteins, after eating a standardized breakfast meal at the first visit and after taking 14 doses of oral semaglutide over two weeks before the second study visit. The food (mixed meal breakfast) we will be studying is specially prepared to contain a set amount of protein, carbohydrates, and fat. The investigators hypothesize that understanding how the acute biochemical response to oral semaglutide differs by genetic variation will generate insight into drug mechanisms and type 2 diabetes pathophysiology.

Assessment of Topical Minoxidil on Intraoperative Flap Perfusion and Cutaneous Flap Viability in Breast Recon
The purpose of the study is to determine whether pharmacologic delay using minoxidil in patients undergoing bilateral risk reducing mastectomy with reconstruction could achieve improvement in flap perfusion and flap viability at the time of surgery. Patients will undergo randomization of their breasts to determine which breast will receive the experimental intervention and which breast will serve as the internal control (receive placebo). The experimental breast will receive the novel pharmacologic delay treatment, 5% minoxidil, while the internal control breast will receive the current standard of care, which does not include any topical application prior to surgery - a placebo control will be used. This will be a triple-blind study, where both the participants and investigators will be blinded to which breast will receive the intervention. The patients will receive two bottles "compound A" and "compound B" with directions from the pharmacy for which compound to apply to each breast. Product will be applied for 2 weeks prior to planned surgery. Surgery will proceed without any changes to standard practice.

Pre Pectoral Implant for Immediate Breast Reconstruction Using Single Port Endoscopy in Prophylactic Indication
Implant-based reconstruction is currently the most common choice for mastectomy reconstruction. Whatever the choice of mastectomy incision, a scar remains on or near the breast volume. Current techniques involve partial or total coverage of the implant with the pectoralis major muscle, to prevent exposure or infection. The muscle dissection technique applied has functional and cosmetic consequences. In this study, an endoscopic approach will be evaluated. This new surgical technique, using a single-port endoscopic way, will put the scar is in the axillary area, away from the breast. The hypothesis is that this delocalized scar potentially reduces the risk of exposure and allows placement of the implant in the subcutaneous space, with no manipulation of the pectoralis major muscle.

Barriers and Facilitators of Parent-Child Communication in Children With Cancer Predisposition
Testing children, adolescents, and young adults (CAYA) for a genetic risk for cancer can help with early prevention and detection of cancers through regular follow-ups and medical care. After receiving genetic test results, CAYA may not accurately understand what their results mean, and parents are often unsure about talking with their CAYA about their genetic risk for cancer. By understanding how parents communicate with their CAYA, the investigators can improve future genetic education to reduce cancer risk. Primary Objectives: * Identify qualities of parent-CAYA (child, adolescent, and young adults) communication about CAYAs' genomic cancer risk, and their association with CAYAs' psychosocial and prevention outcomes. * Examine the association between sociodemographic, cancer-related, and psychosocial factors and parent-CAYA communication regarding CAYAs' genomic risk for cancer. * Identify barriers and facilitators of parent-CAYA communication regarding CAYAs' genomic risk for cancer.

EXOME Analysis Position in the Strategy of Genetic Predisposition Factors Identification in Early-onset Cancer
5 to 10% of cancers are due to the presence of a constitutional genetic alteration. It can be inherited from parents (family form) or by accident, in the first moments of life after fertilization (sporadic form). In both cases, this genetic alteration is constitutional and transmissible to descendants. It is hereditary. When an hereditary early form is suspected, several well-known genes generally involved in genetic predispositions to cancer are found by a technique called " gene panel ". However, this analysis does not always identify the genetic predisposing factors for cancer. New techniques called "high-throughput exome sequencing (SHD-E)", allow more than the analysis of the the gene panel. These analysis allow to identify alterations in other genes that could contribute to the development of cancer. The objective of the Ex²trican study is to show, from patients with early cancer (sporadic or familial form), that this approach to exome sequencing can be effective to identify new genetic risk of cancer, when the first panel analysis of genes is negative.

The Effect of rs7903146 Genotype on Islet GLP-1 Production in Humans
The investigators recently demonstrated that blockade of Glucagon-Like Peptide-1's (GLP-1) receptor (GLP1R) results in changes in islet function without changes in circulating GLP-1. These effects are more pronounced in people with early type 2 diabetes (T2DM) in keeping with increased expression of PC-1/3 and GLP-1 that is observed in diabetic islets. However, its regulation is at present unknown. Common genetic variation in the TCF7L2 locus (T-allele at rs7903146) arguably confers the greatest genetic risk of T2DM. It is associated with α- and β-cell dysfunction. TCF7L2 (the product of TCF7L2) was first described as the transcription factor necessary for proglucagon expression in intestinal L-cells (which secrete GLP-1). This led to speculation that TCF7L2 confers risk of diabetes via changes in circulating GLP-1. This has turned out to not be the case. This raises the possibility that these diabetogenic effects are mediated via an inability of islet GLP-1 to adapt to rising glycemia. Therefore, this experiment will determine the contribution of islet GLP-1 to the functional abnormalities of the islet associated with the TCF7L2 locus.
