How do you decide which IV opioid to use for symptom relief at the end of life?
For patients at the end of life who need IV medications for symptom relief, I choose morphine, hydromorphone, or fentanyl depending on the patient's baseline opioid tolerance, symptom burden, and their kidney and liver function. Morphine is the lowest potency of these three options and is a good cho...
Do you add adjunctive gentamicin and/or rifampin for treatment of prosthetic valve Staphylococcus aureus endocarditis?
No, we do not add adjunctive gentamicin for treatment of Staphylococcus aureus (SA) prosthetic valve endocarditis (PVE). The potential benefit of using an aminoglycoside in this setting is minimal, if any, and is outweighed by the risk of toxicity.With respect to using rifampin, it depends on whethe...
Do you find consumer grade wrist actigraphy useful in measuring sleep quality and duration?
Consumer wearables are advancing quickly, and there is a lot of variation in their performance, particularly in those with sleep disorders. Unfortunately, there is a wide variation in the performance of devices, even ones using the same signals to calculate sleep/wake. Additionally, orthosomnia is a...
Do you routinely integrate telomere length testing into the evaluation of patients with ILD?
"Routine" would be a stretch, but I have dramatically increased my utilization of telomere length testing with the publication of recent studies, including this one. I do not check telomere lengths in patients when I don't think it will impact my management, but there is uncertainty surrounding best...
When do you consider Cheyne-Stokes respirations noted in download data from positive pressure machines to be normal vs abnormal requiring intervention?
I do not have great confidence in the algorithms for CSR detection in CPAP machines (both in terms of false negatives and positives). That said, I agree with Dr. @Dr. First Last that if there is an newly increased amount of central events or CSR on a CPAP report, that should prompt (at the least) a ...
Is there a role for monitoring serum ANCAs to assess ANCA associated vasculitis disease activity?
This is (and remains) a somewhat controversial question. ANCA titers do appear to rise in anticipation of disease flares and patients with persistent titers appear to have more flares. This is especially true for PR3 ANCAs. However, the proximity of flares to rising ANCA titers is not terribly close...
How do you decide on the speed and target of blood pressure reduction for spontaneous intracranial hemorrhage?
I think the target and speed of blood pressure reduction in ICH depend on several variables, including initial SBP, clinical stability, hematoma size, and renal function. For patients presenting with SBP >220, I typically aim to lower the pressure to around SBP 160 over the first 12 hours, then grad...
When giving albumin challenge, for acute kidney injury with suspected hepatorenal syndrome, do you administer a single dose daily or split the dose of albumin?
The main concern about albumin infusions is the potential risk for pulmonary edema (China et al., PMID 33657293). Therefore, I prefer to have albumin administered in divided doses of 25 grams at a time with a max daily dose of up to 100 grams, and I tend to stop IV albumin if the serum albumin level...
In cases of intermediate-risk pulmonary embolism, what factors influence your decision to pursue catheter-directed thrombolysis?
"Intermediate-risk" is a complex term. Patients with intermediate-low risk are not prognostically the same as those with intermediate-high risk (i.e., with elevated cardiac biomarkers and RV dysfunction) (Santos et al., PMID 31017472), and my threshold to intervene on intermediate-high risk patients...
Do you commonly observe acute erythrocytosis in patients with ILD flares being treated with supplemental oxygen and high-dose corticosteroids?
Assuming that this patient does not have erythrocytosis at baseline, my experience is that acute erythrocytosis is not typical. Erythrocytosis caused by hypoxemia typically has a lag of several weeks, even though EPO increases within 48 hours. You commonly see a moderate acute leukocytosis with high...
