Acut. kidney injuries (AKI) are a common problem encount.red by int.rnist. in t.e inpat.ent.and out.at.ent.set.ing. Uncovering t.e et.ology becomes import.nt.in t.iloring t.eat.ent. Point.of-care ult.asound (POCUS), when used in conjunct.on wit. a pat.ent.s hist.ry and physical exam, can quickly ident.fy if hydronephrosis is present.and shed light.on t.e underlying et.ology. In t.is art.cle, we discuss how incorporat.ng POCUS int. t.e init.al assessment.of pat.ent. wit. an AKI can reduce t.e number of unnecessary and expensive formal renal ult.asounds and pot.nt.ally expedit. clinically appropriat. t.eat.ent. t.e purpose of t.is review is t. examine t.e benefit., reliabilit., and feasibilit. of POCUS t. furt.er evaluat. and manage pat.ent. wit. AKI. An ext.nsive review of t.e lit.rat.re was performed and found POCUS t. be a reliable and realist.c met.od for int.rnist. t. incorporat. int. t.eir assessment.of pat.ent. wit. AKI. In t.is art.cle, we also provide inst.uct.on on how t. perform a POCUS exam of t.e kidneys and how t. ident.fy hydronephrosis. Furt.ermore, we discuss t.e challenges we face and ideas for furt.er pract.ce including t.e emergence of hand-held ult.asounds.

Background： Many st.dies examining individual-level correlat.s in yout. ut.lize self-report.rat.er t.an object.ve measures of physical act.vit. （PA）. t.is ut.lizat.on of self-report.may result.in associat.ons t.at.are not.present.when examining object.vely measured PA. t.e present.st.dy invest.gat.s t.e relat.onship bet.een hypot.esized correlat.s of PA wit. object.vely and subject.vely measured PA. Met.ods： Part.cipat.ng children （n 232, 101 males, mean age - 12.3 years） provided a minimum of four monit.red days of PA （via acceleromet.r） and complet.d a survey assessing moderat.-t.-vigorous physical act.vit. （MVPA）, sport.compet.nce, appearance, enjoyment. and self-efficacy. Height.and weight.were measured and body mass index （BMI） was calculat.d. Result.： Hierarchical regression models cont.olling for sex, race, and BMI Z-score showed t.at.only sex and BMI Z-score were significant.correlat.s of object.ve MVPA while only sex was a significant.correlat. of object.ve t.t.l PA. However, in a separat. model examining t.e relat.onship wit. subject.ve MVPA, enjoyment.of PA and self-efficacy for PA were t.e only significant.correlat.s of self-report.d PA. Conclusion： Measuring MVPA via self-report.versus acceleromet.y produces considerably different.result. in a sample of young adolescent.. Fut.re st.dies should use caut.on when select.ng out.ome measures if t.e int.nt.is t. ident.fy modifiable correlat.s of MVPA in yout..
