Affirmed by unpublished PER CURIAM opinion..

Unpublished opinions are not binding precedent in this circuit.

Charles Edward Thomas appeals the district court’s order adopting the magistrate judge’s recommendation to dismiss, after a 28 U.S.C. § 1915 (2012) review, Thomas’s claims brought pursuant to 42 U.S.C. § 1983 (2012), the Americans with Disabilities Act, 42 U.S.C. §§ 12101-12300 (2012), and the Health Insurance Portability and Accountability Act of 1996, 42 U.S.C. §§ 1320d-1320d-9 (2012), and declining to exercise supplemental jurisdiction over Thomas’s state law claims. Thomas has also filed with this Court several motions seeking additional, relief. We deny the pending motions and affirm the district court’s judgment.

The timely filing of specific objections to a magistrate judge’s recommendation is necessary to preserve appellate review of the substance of that recommendation when the parties have been' warned of the consequences of noncompliance. Wright v. Collins, 766 F.2d 841, 845-46 (4th Cir. 1985); see also Thomas v. Arn, 474 U.S. 140, 106 S.Ct. 466, 88 L.Ed.2d 435 (1985). Moreover, we limit our review to the issues raised in the appellant’s informal brief. See 4th Cir. R. 34(b). Thomas waived appellate review of the district court’s dispositive holdings by failing to file specific objections to the magistrate judge’s dispositive recommendations after receiving proper notice, and by failing to chállenge the district court’s dispositive holdings in his informal brief.

Accordingly, we deny the pending motions and affirm the district court’s judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this Court and argument would not aid the decisional process.

AFFIRMED.
