The Board denied the Veteran's claim of service connection for his left elbow condition, finding that there was no evidence linking the current disability to an in-service injury or event.

The Board remands the claims for service connection for right foot, left elbow, left hip, left ankle, and diabetes mellitus to obtain additional medical evidence.

The Board granted service connection for an acquired psychiatric disorder and a right foot disability, as secondary to service-connected disabilities. The appeals for service connection of prostate cancer, diabetes, GERD, and hypertension were dismissed due to the RO's subsequent grant of these conditions.

The Board granted service connection for several conditions, including OSA, cervical spine condition, left shoulder condition, right shoulder condition, and others, but dismissed appeals for obesity, TMJ, insomnia, left elbow, and right elbow. The Board also denied an earlier effective date for a 70% rating for acquired psychiatric disorder.

The Board denied service connection for multiple conditions, including gastrointestinal, headache, foot, elbow, and hand conditions, as the evidence did not support a current diagnosis or symptoms related to these conditions during the pendency of the claims.
