How do you approach the choice of basal-bolus insulin vs correctional insulin alone to manage hyperglycemia in a hospitalized older adult with type 2 diabetes and significant frailty?
Frail older adults with type 2 diabetes, compared to their less-frail counterparts, may have less predictable oral intake, and you may have more difficulty obtaining an accurate medication reconciliation. You may need to review facility records or speak to multiple collateral historians to find out ...
In adults ≥80 years with TSH 6–10 mIU/L and minimal symptoms, do you initiate levothyroxine, monitor, or avoid treatment entirely?
I tend to check free T4 in this situation. Aging is associated with some elevation in TSH value up to 10 mIU/L with normal free T4, and in those patients, levothyroxine is not needed. In some patients, I have seen it rise above 10 with normal free T4. Supplementing levothyroxine to lower serum TSH w...
When do you check vitamin D levels in patients with depressive symptoms?
I routinely check 25-OH D in all my patients. Given that half the population is deficient and that we now know the role of vitamin D not only for bones but in mood, cognition, and immunity. We need to be aware of deficiencies and replete if low. Moreover, ideal levels are 60-80, not just over 29 as ...
Do you require levothyroxine to be taken on an empty stomach in patients with stable hypothyroidism, or is dosing with breakfast acceptable with dose adjustment?
Ideally, levothyroxine should be taken on empty stomach but if a patient is taking it with breakfast and has a stable normal TSH, it is okay to continue but if TSH fluctuates change to empty stomach.
Is thyroglobulin typically elevated in patients with Hashimoto's thyroiditis on adequate thyroid hormone replacement?
Any thyroid condition where there is an enlarged goiter or stimulated cell by a high TSH will increase the thyroglobulin levels. A long time ago, when I was a fellow, Tg's were measured to correspond with MNG growth. In those situations, I have seen levels in the 1,000's, and a large nodule can have...
How would you counsel patients with Type 1 or Type 2 diabetes mellitus and heart failure on the use of SGLT-2 inhibitors when they have a history of DKA?
Making a recommendation to prescribe this class will really require a case-by-case clinical assessment. It is clear that SGLT-2 inhibitors are very effective in preventing hospitalization for heart failure, and so we will want to suggest their use whenever possible. But it is also clear that DKA (mo...
Do you temporarily hold diuretics when measuring 24-hour urine calcium levels in the evaluation of primary hyperparathyroidism?
It is mandatory to stop diuretics at least 2 weeks before evaluating a patient for PHPT. One should have a fasting blood sample on the morning of the end of the collection for calcium phosphate and PTH to complement the urine collection. Thiazide-type diuretics raise serum calcium and lower urine ca...
How do you counsel patients with metabolic syndrome who decline statin therapy and have low coronary calcium scores regarding their long-term CVD risk?
This is a great question with many ramifications, and I can only give an incomplete answer that includes personal opinion. First, what is the risk? The MESA Risk Score Calculator (check it out) gives a CAC percentile score as well as a 10-year risk. The 10-year risk may be low, but a high percentile...
In an obese male with low testosterone, would you initiate testosterone replacement therapy at the initial visit, or start tirzepatide first and monitor for improvement in testosterone levels and erectile function?
Dr. @Dr. First Last has given a thoughtful answer. Assuming no evidence of a structural hypothalamic-pituitary-testicular (HPT) disease (normal prolactin, LH, and FSH in the low-normal to normal range, normal free T4), the best approach is weight loss for these men. Whether to try lifestyle changes ...
Do you get DEXA scans routinely before starting ADT for prostate cancer or endocrine therapy for breast cancer?
When initiating long-term ADT, I order a DEXA scan, check vitamin D level, ensure adequate dietary calcium intake, and discuss weight-bearing exercise/refer to PT when appropriate. I also continue check DEXAs every 2 years unless they otherwise meet criteria for a bone-modifying agent (mCRPC with bo...
