A

32% positive only 8% where clinical

Q

How do male dogs have natural bacteriostatic properties in urine

A

Zinc in prostatic secretions

20
Q

JVIM 2019 Did the addition of meloxicam to phenoxybenazimine and alprazolam change the rUO

A

No difference in the two groups

5Fr cath

21
Q

JVIM 2019: What are the limitations of the sedivue

A

Good for RBC, WBC, Ca Ox, Struvite

No good for epithelial cells

22
Q

JVIM 2019 in comparission to creatine how do SDMA and Cystin C as markers of decreased GFR.

A

Creatinine and SDMA good markers for decreased GFR (performed equally) but Cystin C is not
If one is elevated/normal (Cr/SDMA) Others can be good indicator if true disease

23
Q

JVIM 2019 What dogs are at higher risk of developing Calcium oxalate stones

A

Small breed dogs specifically MN schaunzer, bichon frise

8.4 yrs +/- 2.8 yrs

24
Q

JVIM 2019 How does fibroblast growth factor 23 change with SDMA in non azotemic geriatric cats

A

FGF 23 increased when SDMA increases also has higher creatinine

25
Q

JVIM 2019 what is the proposed underlying cause/contributor to proliveritive cystits in dogs

A

Bacteria in the tissue may be part of underlying causes. Urine and tissue cultures likely underrepesent as staining was positive

26
Q

JVIM 2019 what biomarker is the best ad correling renal function in dogs undergoing IVF or IHD with CKD

A

SDMA correlates better than creatinine to severity of CKD for dogs with IVF or IHD
Although SDMA is dialysized, less is able to be reduced with increasing severity of CKD.

27
Q

JVIM 2019: In dogs how did uNGAL compare in progressive CKD, stable CKD, and pre-renal azotemia

A

Increased most significantly in dogs with progressive CKD.

no stat difference in stable CKD or pre-renal azotemia

28
Q

NEJM 2009 RENAL trial. What was the outcome difference for high intensity CCRT vs Low intensitiy CCRT

A

There was not difference in mortality at 90 days. Complications occured in both groups although disequilibrim occured mostly in the high intensidty

29
Q

JVIM 2012 What was the outcome of Level 2 AKI for hospitalizations patients and when did it affect oucome

A

Level 2 Crea 1.6 mg/dl and Change of 0.3 mg/dl

If observed on days 2-7 in dogs and 3-7 in cats 3 times more likely to die in 30 and 90 days.

30
Q

JVIM 2011 What were the histologic lesions noted with pyometra in the kidneys

A

UPC> 0.5 tubulointerstitial neprhritis
UPC > 1.0 glomerulosclerosis
None had glomuleronephritis as previously thought

31
Q

JFMS 2011 What resulted in more non survivors and what was noted in cats that had a higher rUO

A

Ionized calcium higher (1.08) in survivors vs. Non-survivors (0.88)
Recurrence higher with lower pH at presentation

32
Q

JVIM 2011 How did albuminuria, survivor predictor index score and c-reactive protien associate with survival in critically ill dogs

A

C-Reactive protien is not an predictor of survivial
Lower albuminuria resultes in survivial
SPI score also associated with survivial

33
Q

JVIM 2015 What led to an increased survival in dogs with AKI

A

Increased GFR, Increased urine production. and decreasing functional clearance of Na (extraction ratio used).
K excretion less susceptible likely due to DCT less damage compared to PCT

34
Q

JAVMA 2018 what increased the risk of rUO in the standard care group

A

Increasingly abnormal urine color at time of removal stat increased rUO at 30 days.

35
Q

JAVMA 2018 how did the outpatient care group compare to the standard care group.

A

Standard care best 11 % rUO

Outpatient cath 31% rUO

36
Q

JAVMA 2018 What is the diagnostic utility of renal FNAs

A

72% were considered diagnositics
Neoplasia similar sen/spec for other organs in body
78/50

37
Q

JAVMA 2018 what percenterage of dogs with Bacteruria in CKD dogs

A

18% with 45% of those subclinical and 40% with pyelonephritis

38
Q

JAVMA 2018 how long did the cystotomy sites remained thickened and when could hyperechoic foci be detected

A

Noted for up to 3 months.

Hyperechoic foci were noted in 11/18 dogs at a mean of 17 days post surgery

39
Q

JAVMA 2018 How is canine urine samples affected by refrigeration with and without TSB

A

No stat difference in refrigerated vs direct submisison but there were 2 less that grew bacteria.
TSB refrigerated was stat different than no refrigeration and should not be used.

40
Q

JAVMA 2018 how does microscopic blood contamination affect UPC and dipstick

A

May increase UPC

Also affects bilirubin, ketones, pH, USG, but does not alter glucose

41
Q

JAVMA 2018 What is the prognosis with uroabdomen and what was noted to result in decreased survivial

A

79% survival to discharge. Serum creatinine was not associated with survival
4/5 medically managed successfully

42
Q

JVIM 2018 How was hyperthyroid related to SDMA prior to i131 treatment in cats

A

Increased pretreatment SDMA highly specific 98% but not specific.
Hypterthyroid cats that became hypothyroid were azotemic.

43
Q

JVECC 2015 What are the two criteria used for AKI in humans

A

RIFLE: risk, injury, failure, loss, end stage
KIDGO: Kidney disease improving global outcomes

44
Q

JVECC 2015 How is uNGAL associated with AKI

A

uNGAL increases 12 hrs before serum NGAL and creatinine in AKI

45
Q

JVECC 2015 How do chloride rich fluids contribute to AKI

A

Activates the macula densa and induces renal afferent arteriole vasoconstriction

46
Q

JVECC 2015 What is the eitology of Sepsis induced AKI

A 
ischemia/reprofusion
Inflammation
oxidative stress (ROS)
Epithelial dysfunction- renal tubular dysfunction; Activation of tubular glomerular feedback
sublethal cellular injury
