The purpose of this study is to examine the efficacy of Code of Respect (X-CoRe) multi-level sexual assault (SA) and harassment (SH) prevention program in improving psychosocial determinants (e.g., knowledge, skills, self-efficacy, attitudes) related to respectful/disrespectful relationships, to examine the efficacy of X-CoRe in reducing SA and sexual harassment SH victimization and to examine the efficacy of X-CoRe increasing bystander behavior and improving unit cohesion and mission readiness by decreasing secondary risk and harmful behaviors (e.g., alcohol misuse, intimate partner violence, suicide ideation). The study will be conducted at at Joint Base McGuire Dix-Lakehurst (JBMDL) located in Burlington County, New Jersey, and participants will be cluster-randomized at the level of the squadron to one of two conditions: the X-CoRe program or a control condition.

The goal of this clinical trial is to compare an active intervention versus a standard of care control in reducing alcohol use among pregnant women. The main questions it aims to answer are whether a motivational intervention can: 1. increase the proportion of women detected with a laboratory-confirmed negative phosphatidylethanol (PEth) test during pregnancy, and 2. reduce the proportion of adverse birth outcomes among infants. Participants will be offered (1) a self-paced computer-delivered alcohol reduction intervention to enhance knowledge, norms, and motivation for alcohol reduction and (2) a nurse-delivered component to reinforce the computer-delivered content and address women's questions. Both components are theory-driven, based on Motivational Enhancement Theory (MET), and use motivational strategies to promote alcohol reduction.

The NACTN Spinal Cord Injury Registry is a network of clinical centers collecting de-identified data from patients admitted through the Emergency Department of a NACTN center at the time of injury with an initial (first time) spinal cord injury (SCI). Information will be collected on the natural history of SCI and course of treatment through the first 12 months from the date of injury or long as medically indicated. Data collected includes imaging information from CT or MRI scans, neurological and general medical outcome and rehabilitation evaluation. No intervention is given other than standard of care for spinal cord injury, intensive monitoring and frequent follow up care.

This study is researching an experimental drug called REGN7508 versus Acetylsalicylic Acid (ASA) (each called "study drug"). The study is focused on adults undergoing elective, unilateral (one side) total knee replacement surgery. The aim of the study is to see how effective the study drug is at preventing Venous Thromboembolism (VTE) and other related diseases after total knee replacement surgery compared to acetylsalicylic acid. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects)
