Before COLLOTON, WOLLMAN, and KELLY, Circuit Judges.
                       ____________

PER CURIAM.
       Patricia Ann Riniker appeals the district court’s1 affirmance of a decision
denying her disability insurance benefits, which we review de novo. See Combs v.
Berryhill, 

, 645-46 (8th Cir. 2017) (ensuring that substantial evidence
on record as whole supports decision). We agree with the district court that because
the administrative law judge (ALJ) gave several valid reasons for discounting
Riniker’s subjective complaints, any error based on the ALJ’s failure to mention her
work history in his credibility analysis was harmless. See Bryant v. Colvin, 

, 782-83 (8th Cir. 2017) (this court defers to ALJ’s credibility determination if it
is supported by good reasons and substantial evidence). As to the remaining issues
Riniker raises on appeal, they are new and she has not shown that manifest injustice
would result if this court declines to consider them. See Gragg v. Astrue, 

, 938 (8th Cir. 2010) (declining to consider issue not raised in district court as
appellant made no showing that manifest injustice would otherwise result). The
judgment is affirmed.
