How do you use IVC caliber and collapsibility to guide decisions about diuresis?
I use IVC caliber in conjunction with my lung exam to assist with the assessment of right and left atrial pressures respectively. The IVC assessment has many caveats in different patient populations, and evaluation with POCUS can be done in two planes to better understand IVC shape.Caveats - IVC siz...
How do you suggest using POCUS to detect or confirm a pneumothorax?
Great question - yes, there are mimickers of "lung point" (known as pseudo-lung point) such as pleural-based blebs, anatomical junction between heart/lung or between two lobes, focal adhesions - to name a few. On top of this, searching for a lung point in a deteriorating patient can delay interventi...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
Do you prescribe empiric antibiotics to patients with CAP who test positive for a respiratory virus?
I do not start antibiotics when there is a detected viral etiology. And I tend to stop them if they were started. Obviously, this changes if the symptoms worsen and/or I suspect a bacterial superinfection. Another caveat would be in a patient with underlying COPD where Azithromycin may play a role i...
What are your vaccine recommendations while patients are on biologics?
Live vaccines are best completed at least a month before initiation of biologics when these are appropriate (e.g., MMR, chickenpox, yellow fever). The data on non-live vaccines is limited. I personally think that some degree of protection is better than none. I will not interrupt biological therapy ...
How do you counsel patients who are hesitant to try behavioral therapies for insomnia instead of starting a sleep medication?
I try to be very understanding of the desire to have an easier solution to sleep difficulties, which are so common. It is challenging that our gold standard and best strategies to help people sleep better require a lot of effort on the patient's part. Starting with that validation can be very helpfu...
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...
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...
Which biologics for asthma have data regarding mucus plugging?
There have been multiple studies on biologics investigating the effects on mucus plugging (as measured by the CT mucus plug score of the number of pulmonary segments with a mucus plug, established by Dunican et al., PMID 29400693). In these studies, high mucus plug scores correlate with T2 high biom...
Do you routinely prescribe dry powdered inhalers over metered dose inhalers for the purpose of addressing carbon emissions?
Unfortunately, the choice is dictated by the patient’s insurance and there are few patients with airway hyper reactivity who may not tolerate dry powder inhalers. Agree in principle, hard to practice. Curious what others do.
