identified a higher proportion of metabolic acidosis

how are glucose and insulin affected by alpha 2 agonists

Answer 7

Answer 8

lower mean protein and RBC count

Question 9

Answer 9

yes, increasingly so with repeated cycles, so unfrozen samples should be used

Question 10

how does nebulizing dex affect bacteria in the URT

Answer 10

decreased microbial diversity - EHV-2 increased and EHV-5 decreased

Answer 11

there was a significant decrease in strep

Question 12

how does transport affect gastric ulceration

Answer 12

significantly increases risk of squamous ulcers
feeding prior can = delayed emptying
despite increased pH

Question 13

most frequently isolated bacteria from infected IVC’s in cattle/sheep/goats

Answer 14

daily SC injections of desmopressin acetate, a synthetic AVP(ADH) analog

Question 15

Paraoxonase-1

Answer 15

biomarker that decreases during inflammation, like SIRS - low value may predict negative outcome

Question 16

what is significantly lower in non-surviving small ruminants with re-feeding syndrome

Answer 16

P

Question 17

non thyroidal illness syndrome in foals

Answer 17

foals born from mares with placentitis

sick non survivors had significantly lower T3:cortisol and T4:cortisol ratio vs survivors at 12 and 24 hours – TH alone not associated with outcome though

placental infections impair fetal thyroid function

single tumor at the thoracic inlet

Answer 20

weight loss
hypercalcemia
hyper PTH

Question 22

in the 2020 EJV Cozar paper, survival to discharge was associated with

Answer 22

lower SAA at 5 days post op

Answer 24

age less than 3 years

remission of headshaking with PENS

Answer 26

53%, median time 9.5 weeks

Question 27

APD’s > 25 per 24hrs in the 5d period post AF conversion indicates what

risk of AF recurrence in the year following TVEC Tx

Question 28

equine rhinitis A virus respiratory dz

Answer 28

• attack rate for infectious resp dz 97.9%
• median recovery time 6d
• later born foals less likely to recover quickly

about 44% survivors in the Dunkel 2020 study

Question 31

atypical myopathy non survivors had

Answer 31

increasing CK and TG

Question 32

acylCo-A dehydrogenase deficiency
-impaired mitochondrial metabolism
-excess lipid within myofibers

Answer 32

atypical myopathy

Question 33

second most common strangulating intestinal lesion in horses

Answer 33

epiploic foramen entrapment

Question 34

most important predisposing factor for epiploic foramen entrapment recurrence

Answer 34

intra-abdominal pressure

Question 35

most frequent location of intestinal neoplasia (dyson 2020)

Answer 35

jejunum

Question 36

procalcitonin

optimal serum total protein for neonatal dairy calves associated with health and growth

Answer 37

6.0 - 8.5 g.dL

Question 38

most common genital tract tumor type in goats

Answer 38

adenocarcinoma

– high odds of mets
– increased odds of euthanasia in does that are straining
– pygmy goats over-represented
– median age 10yrs
– overall survival low 30%

Question 39

what parameters were associated with neuro signs in foals (Dunkel 2020)

Answer 39

Na (low) and BUN (high)

Question 40

Dunkel found that ___ Na was associated with neuro signs in foals

Answer 40

low

hypo defined as Na <125mmol/L

Question 41

most important risk factor for incisional hernia formation

Answer 41

infection
30-60 days post op

Question 42

sodium correction

Answer 42

Current recommendations are to treat chronic and acute hyponatremia equally conservatively if Na+ concentrations are <120 mmol/L.

In symptomatic cases, an increase of 4 to 8 mmol/L (approximately 5% increase in Na+ concentration) over
the first 6 hours of therapy often alleviates clinical signs, and further increases should not exceed a total of 10 mmol/L/d.

In cases with no neurological symptoms, a gradual increase by 10% per day should be targeted.
