Contributor: Rachael Duncan, PharmD BCPS Educational Pearls:  According to the Department of Public Health and Environment who puts out a weekly report on the influenza virus in Colorado, there appears to be less influenza in Colorado than previous years  A milder influenza outbreak is likely due to mask wearing and social distancing practices  There have only been 22 hospitalizations for influenza in Colorado since the start of the flu season back in September and 0 outbreaks in long-term care facilities  Xofluza (baloxavir marboxil) is an antiviral PA endonuclease inhibitor and was approved by the FDA in 2018 for uncomplicated influenza in patients 12 years and older that have been symptomatic for less than 48 hours Patient’s getting Xofluza must be otherwise healthy or at risk of developing influenza-related complications  Due to limited data, Xofluza would not be a good option for those that are inpatient or critically ill and is best utilized for patients who are being seen in the emergency department and will be sent home  Currently Xofluza is not approved for complicated patients, pregnant patients or those that are breast-feeding which limits its use  When compared with Tamiflu in phase 3 studies, Xofluza was superior to placebo and similar to Tamiflu in shortening the duration of illness  Xofluza is a single dose that is weight based and appears to be very well tolerated with some adverse effects including headache, nausea and diarrhea   Xofluza showed a quicker recovery compared to Tamiflu by 8 hours which could be related to its one-time dosing  Cost is a limiting factor for the use of Xofluza. Tamiflu costs around $25 where as Xofluza (only available as brand name currently) is $156 at the cheapest  Pharmacists are still encouraging everyone to get their influenza vaccines despite less influenza cases this year  References:  Cdphe.colorado.gov. 2021. Influenza (flu) | Department of Public Health & Environment.

Contributor: Katie Sprinkel, MD Educational Pearls: Commonly known as “acid,” LSD is seeing a resurgence in the population as a recreational hallucination Onset is about 30 minutes with peak pharmacologic effects at 2-4 hours, the drug’s half life is 3 hours resulting in some prolonged effects While there is not an significant addictive component of LSD, tolerance for LSD does occur and prolonged usage is associated with increased incidence of schizophreniform disorders Hallucinations and pseudo-hallucinations (sensory misperceptions) are typical of LSD intoxication, other common signs of intoxication include nausea, diaphoresis, tachycardia, mydriasis, and hypertension More serious effects can be coma, hyperthermia, seizures, cardiac arrest, serotonin syndrome (with concomitant SSRI use) and coagulopathy, although the dose to cause these effects is very high Treatment is decreasing sensory stimulation, benzodiazepines in some cases, and symptomatic treatment - no specific antidote exists References Blaho K, Merigian K, Winbery S, Geraci SA, Smartt C.

Educational Pearls: Atropine has been shown to reduce hypersalivation as well as nausea and vomiting induced by ketamine sedation. Atropine can increase the occurrence of a transient rash, as well as tachycardia. There are no guidelines that recommend for or against atropine use in pediatric patients undergoing ketamine induced sedation. Ultimately, it is the providers decision to include atropine when performing ketamine sedation. Pediatric dosing for atropine is 0.01mg/kg IM. References    Heinz P, Geelhoed GC, Wee C, Pascoe EM.

Contributor: Jared Scott, MD Educational Pearls: Bilirubin is natural breakdown product of red blood cells but can be neurotoxic if levels become too high Fetal red blood cells are fragile and break down easier, leading to higher bilirubin levels in neonates  Immature livers and increased intestinal absorption from sterile bowels also contribute to elevated levels and jaundice in all neonates Other risk factors for neonatal jaundice include: temperature instability, poor feeding, hypoxia at birth, and being of East Asian descent Neonatal bilirubin levels are referenced to time since birth using a nomogram to determine the need for light therapy (or exchange transfusion) References Mitra S, Rennie J.

Contributor: Cheyenne Bean, PharmD Educational Pearls: Bactrim (TMP-SMX) is a sulfa antibiotic used for a number of infections but can have untoward effects. Hypoglycemia can be induced by the sulfa component of Bactrim, which binds receptors in the pancreas causing insulin to be secreted, dropping blood sugar levels. Oral diabetic medications, specifically sulfonylureas, when taken with Bactrim most often lead to these hypoglycemic episodes. Hyperkalemia can be induced by Trimethoprim by blocking potassium excretion in the kidney, so Bactrim in combination with ACE inhibitors/ARBs/spironolactone can induce high potassium. When prescribing Bactrim, remember to check home medications and if a patient is taking an above medication, check a baseline BGL and potassium.

Contributor: Gretchen Hinson, MD Educational Pearls: Viruses mutate frequently and a new variant of COVID has been found in the United Kingdom. Mutations typically occur due to transcription errors during virus replication leading to slight changes in the virus which can alter its virulence, and this UK mutation has shown more infectivity. The UK variant was first identified on 9/20/20 and sequenced in October The variant has a mutation of the spike protein with increased receptor binding capacity, making it more efficient at infecting cells Children seem to be more susceptible to this variant as compared to the prior COVID strains.

Contributor: Peter Bakes, MD Educational Pearls: Hyperacute T waves can occur immediately and typical last less than an hour Hyperacute T waves are typically broader than peaked T-waves, which are associated with hyperkalemia ST elevation which usually starts within an hour of the inciting event and can last up to a few days, and often follows the hyperacute T-waves Q waves can begin at the time ST elevation begins and can remain permanently T waves can invert before normalizing again days later References Levis JT.

Contributor: Jared Scott, MD Educational Pearls: EKGs look at different angles, or vectors, of the heart’s electrical conduction as it travels through the heart. Knowing how to read these vectors is essential in diagnosing locations of cardiac pathologies  Leads II, III, and aVF follow an inferior path, so ST elevation in those leads indicates inferior involvement Major complications more common with inferior STEMIs can include:  hypotension which can be made worse by nitroglycerin Severe bradycardia due to SA/AV node involvement Inferior STEMI, barring no hypotension or bradycardia, have better mortality than other types  References Warner MJ, Tivakaran VS.
