Do you manage mild-to-moderate diabetic ketoacidosis with a subcutaneous rapid-acting insulin protocol rather than an IV insulin infusion?
Yes, SC rapid-acting insulin can be used in the mild cases of DKA, provided that dehydration is not severe enough to affect insulin absorption. Small, frequent doses every hour may replace the IV insulin in mild cases. A good tip is to start correcting fluid loss in the first or two hours before sta...
Are there instances when you recommend central line access when treating a patient using 3% sodium chloride for management of severe hyponatremia?
At UCLA, our hospital policy allows for the administration of 3% sodium chloride via a peripheral intravenous catheter at infusion rates up to 50 mL/hr (Perez & Figueroa, PMID 28471928, Jones et al., PMID 27965228, Mesghali et al., PMID 30745195). Moreover, a prospective, observational study demonst...
How has COVID-19 altered your recommendations for invasive mediastinal staging for NSCLC?
I just had this discussion with our chief of interventional pulmonolgy at MD Anderson. Some of his faculty are being asked to staff our COVID-19 patient floor. In addition, bronchoscopy procedures should be considered high-risk procedures, and are required to have at least 45 minutes in between proc...
At what age do you stop LDCT chest for lung cancer screening?
One of Medicine's three priority-ordered duties is to postpone death. This also pertains to persons who have reached age 81. Lung cancer can occur longer than 15 years after cessation of smoking. Even if surgery can't be done, primary radiation of Stage 1 squamous cell lung carcinoma can result in p...
Are there still clinical situations in which you deliberately treat patients with a DOAC besides apixaban?
Thank you for your question. Apixaban has been my preferred agent for a long time for patients requiring therapeutic anticoagulation. Apixaban’s lower bleeding risk was shown prior to and now has additional evidence to support this with the COBRRA trial. The risk is also ameliorated by the safety in...
Do you administer calcium to patients with K > 6.5 without EKG changes?
No. But our ER does as a reflex and I don't have a problem with that. It used to drive me nuts bc it sent the wrong message, as though Ca lowers [K] level (of course it does not, it just decreases cardiac effect). But you don't know how fast they are being seen, how fast they will get treated, so I ...
When would you consider glucocorticoids as adjunctive therapy for for community-acquired pneumonia outside of the ICU setting?
Thank you for bringing this new study to my attention; I hadn't seen it yet. After reviewing the article, my practice regarding steroids remains unchanged. While the trial was well-executed, and it is laudable to see such research coming out of a limited-resource setting, that environment differs si...
What clinical features push you to add dupilumab instead of escalating ICS dose in a patient with biomarker-high asthma and recurrent exacerbations?
The Phase 3 QUEST study addressed this question and found that adding dupilumab to medium-dose ICS/LABA provided significantly better control than placebo plus high-dose ICS. However, this study did not look at actual dose escalation of the ICS prior to instituting the biologic. They also found no s...
What findings on routine monitoring PFTs prompt you to pursue HRCT in your patients with SARDs?
That’s an excellent question, and the strategy might vary somewhat by the specific SARD, but in general, in any SARD patient undergoing annual PFTs, the presence of any of these should prompt an HRCT to evaluate for the development of ILD. FVC drop ≥ 10% DLCO drop ≥ 15% Moderate decline in FVC (5-9...
How do you counsel patients who are concerned that discontinuation of certain chronic medications may actually perpetuate suffering at the end of life?
Great question, and it’s very nuanced. I’ll share how I typically approach this based on my experience. In the end-of-life care setting, when I review a medication list, I go through every single one and ask: “What is the purpose of this medication in this particular case?” For example, anticoagul...
