Q

What drugs were associated with GB mucocoele formation?

A

JVIM 2015; thyroxine (treatment for hypoT), Cushings treatment, imidocloprid - the latter particularly in shetland sheepdogs

18
Q

What is the difference in leptin in dogs with GBM?

A

JVIM 2017: Increased serum leptin and increased leptin and receptor in the GB

19
Q

What is the Sn and Sp for ultrasound to detect GB rupture with mucocoele? Does rupture have prognostic significance?

A

JVIM 2018: Sn 56, Sp 91. Rupture was associated with 2.7 X increased likelihood of death

20
Q

What improved prognosis in dogs with cholangitis/cholangiohepatitis in a retrospective study?

A

JVIM 2018: Cholecystectomy

21
Q

What other congenital disease is gall bladder agenesis associated with?

A

JVIM 2018: Ductal plate malformation

22
Q

does the ammonia concentration correlate with the severity of HE?

A

JAVMA 2015; In this study it did not.

23
Q

What coagulopathy is associated with high disease severity in dogs with chronic hepatitis?

A

JVIM 2017: hyperfibrinolysis

24
Q

What is the most potent mediator of stellate cell proliferation?

A

JVIM Fibrosis review: Platelet derived growth factor

25
Q

What was the impact of cyclosporine treatment on dogs with presumed CH?

A

JVIM 2019: 78% achieved normalisation of ALT. Time to “remission”was 2.5 months. 38% had GI signs and 25% had gingival hyperplasia

26
Q

What is the evidence for autoimmune hepatitis in Dobermans?

A

JVIM 2017: Detected increased levels of anti-histone antibodies in 92% of subclinical and 84% of clinical dobermans - suggestive of autoimmune disease and potential screening test

27
Q

What is the effect of endothelin-1? What may it be increased with?

A

JVIM 2017: Vasoactive peptide; released from endothelial cells and induces vascular smooth muscle and stellate cell contraction. In this study increased in CH dogs and weakly increased in dogs with increased splenic pulp pressures, so possible association with portal hypertension

28
Q

What is p21 and what is its potential prognostic impact?

A

JVIM 2018: Marker of cell senescence, increased expression in liver histology in dogs of this study was associated with reduced survival

29
Q

What are mi122 and mi29 associated with in labradors?

A

JVIM 2019: Serum concentrations were associated with grade of hepatitis and stage of fibrosis in chronic hepatitis in this breed.

30
Q

What time was required to reduce copper in Labrador livers from 710 to 343 with a low copper high Zn diet?

A

JVIM 2015: 7.1 months

31
Q

What is the “name” of the copper transporters and where do they reside? Mutations in genes encoding for these transporters have been identified in which breeds?

A

JVIM 2019: ATP7A (enterocyte; facilitates copper transport into portal circulation), ATP7B (hepatocytes; excretion into the bile ducts). Mutation in the latter is associated with copper overload. Labradors have been identified to have gene mutations, a variant has also been identified in the ATP7B transporter in Dobermans

32
Q

What drugs were identified as potential treatments for HL in cats based on an organoid study?

A

JVIM 2019: T863 an inhibitor for DGAT1 (synthesises triacylglycerol), AICAR via decreasing PLIN2 mRNA; a protein which stabilises lipid droplets

33
Q

What serum vitamin levels have been shown to be lower in dogs with EPI

A

JVIM 2018: Retinol and alpha-tocopherol

34
Q

What contrast ultrasonographic changes can be seen in the pancreas and what neighbouring organ during pancreatitis?

A

JVIM delayed peak perfusion and increased peak intensity and AUC (prolonger hyper echoic enhancement). Duodenal perfusion was also changed (increased peak intensity and AUC)

35
Q

What changes may be seen on CT in dogs with acute pancreatitis?

A

JVIM 2015: enlarged and contrast enhancing, with ill defined borders. Enhancement may be homogenous or heterogenous and in this small pilot study the latter was associated with poorer outcome. May see thrombi.
JVIM 2019: CT better identified dogs with more severe disease as heterogenous contrast enhancement was associated with longer hospitalisation, more relapses and more thrombosis

36
Q

How well does pancreatic ultrasound correlate with Spec cPL for the diagnosis of pancreatitis?

A

JVIM 2019: Weakly. this study used a clinical assessment as the gold standard for diagnosis of pancreatitis and found that the degree of ultrasound changes affected the Sn/Sp of ultrasound, with enlargement, pancreatic and mesenteric changes all being present, Sn 43 and Sp 92

37
Q

In a non blinded JSAP study, what was the effect of prednisolone in acute pancreatitis?

A

JSAP 2019: Faster improvement in CRP, clinical score and reduced mortality

38
Q

What was a positive prognostic indicator in a large retrospective feline pancreatitis study?

A

JVIM 2018; antibiotic treatment

39
Q

Name 4 risk factors for death in pancreatitis.

A

JVIM 2019; SIRS, coagulation disorders, increased creatinine, hypocalcemia

39
Q

Name 4 risk factors for death in pancreatitis.

A

JVIM 2019; SIRS, coagulation disorders, increased creatinine, hypocalcemia

40
Q

is Beta-HB increased in dogs with acute pancreatitis without DM?

A

JVIM 2016: yes, median 0.3 (range 0-2.9), which was higher in sick dogs without pancreatitis/DM and fasted dogs

41
Q

What is the Sn/Sp of FUJI DRI chem lipase for the diagnosis of pancreatitis?

A

JVIM 2016: Sn 100, Sp 89.5

42
Q

what was the reported concordance between snap fPL and spec fPL?

A

JVIM 2019 97% agreement when snap was low, 90% agreement when snap was high
