A new reason to reconsider that antibiotic prescription: The microbiome
But, after the results of many recent studies, it turns out I should not have been so comfortable after all. This should not be a surprise. We should never be overly confident with our understanding of anything in clinical practice.
In this issue, Dr. Martin Blaser discusses his work, which supports the hypothesis that the currently increased prevalence of obesity and diabetes is at least in part due to reduced diversity in the gut microbiome. The increased exposure to antibiotics through prescriptions for women before and during pregnancy, as well as perhaps their exposure to antibiotics in the environment, results in changes to the gut and vaginal flora that influence the developing gut and likely other anatomic microbiomes in the neonate and infant. Fascinating research done in mice, utilizing fecal transfer experiments, is building an evidence trail to support the concept that the microbiome plays a major role in the development of childhood and adult obesity, and the gut microbiome is influenced by its exposure to antibiotics, perhaps given years earlier.
Knowledge of the gastrointestinal and other human microbiomes is exploding. I now wonder how many seemingly random clinical events associated with antibiotic use that were not understood and were easily dismissed as stochastic warrant formal study. Some of my patients with rheumatoid arthritis have described flares after eating certain foods and transient remissions or exacerbations after treatment with antibiotics. An epidemiologic study has linked the likelihood of developing childhood inflammatory bowel disease with exposure to antibiotics. Even more fascinating are observations that the microbiota composition (influenced by antibiotics) can influence the outcome of cardiac allografts in a murine model and the response of certain tumors to immune checkpoint inhibitors in murine and human studies. The mechanism may relate to the effects of the microbiome on immune cell activation and migration. Several disorders have been linked to specific bacteria in the gut microbiome, and others as diverse as cardiovascular events and the acute inflammatory response to monosodium urate crystals (gout) are affected by metabolites generated by bacteria in the gut.
The use of germ-free and antibiotic-treated mice in the laboratory, with selective repopulation of their gut microbiome with flora harvested from other strains of mice or selected humans, will continue to teach us much about the role that these microbes and other inhabitants play in controlling normal and disease-disrupted homeostasis. C difficile overgrowth after antibiotic exposure, and the successful treatment of refractory C difficile with fecal transplantation,1 was just the beginning.
The simple writing of a prescription for an antibiotic is a far more complicated and long-lasting affair than most of us have thought.

Acute necrotizing esophagitis
An 82-year-old man with poorly controlled diabetes mellitus presented to our emergency department with a 1-day history of confusion and coffee-ground emesis.
Biopsy study revealed necrosis of the esophageal mucosa. A diagnosis of acute necrotizing esophagitis was made.
ACUTE NECROTIZING ESOPHAGITIS
Acute necrotizing esophagitis is thought to arise from a combination of an ischemic insult to the esophagus, an impaired mucosal barrier system, and a backflow injury from chemical contents of gastric secretions.1 The tissue hypoperfusion derives from vasculopathy, hypotension, or malnutrition. It is associated with diabetes mellitus, diabetic ketoacidosis, lactic acidosis, alcohol abuse, cirrhosis, renal insufficiency, malignancy, antibiotic use, esophageal infections, and aortic dissection.
The esophagus has a diverse blood supply. The upper esophagus is supplied by the inferior thyroid arteries, the mid-esophagus by the bronchial, proper esophageal, and intercostal arteries, and the distal esophagus by the left gastric and left inferior phrenic arteries.1
KEY FEATURES AND DIAGNOSTIC CLUES
The necrotic changes are prominent in the distal esophagus, which is more susceptible to ischemia and mucosal injury. The characteristic endoscopic finding is a diffuse black esophagus with a sharp transition to normal mucosa at the gastroesophageal junction.
The differential diagnosis includes melanosis, pseudomelanosis, malignant melanoma, acanthosis nigricans, coal dust deposition, caustic ingestion, radiation esophagitis, and infectious esophagitis caused by cytomegalovirus, herpes simplex virus, Candida albicans, or Klebsiella pneumoniae.2–4
TREATMENT AND OUTCOME
Avoidance of oral intake and gastric acid suppression with intravenous proton pump inhibitors are recommended to prevent additional injury of the esophageal mucosa.
The condition generally resolves with restored blood flow and treatment of any coexisting illness. However, it may be complicated by perforation (6.8%), mediastinitis (5.7%), or subsequent development of esophageal stricture (10.2%).5 Patients with esophageal stricture require endoscopic dilation after mucosal recovery.
The overall risk of death in acute necrotizing esophagitis is high (31.8%) and most often due to the underlying disease, such as sepsis, malignancy, cardiogenic shock, or hypovolemic shock.5 The mortality rate directly attributed to complications of acute necrotizing esophagitis is much lower (5.7%).5

Should toe amputation be delayed in diabetic patients with osteomyelitis?
Amputation: Resistance is not futile!
What’s in a toe you may ask? Why worry about saving it? Just amputate and move on ...
Not so! I implore you to resist the desire. We vascular surgeons are accustomed to cutting off toes, even feet and legs. But when it comes to diabetic feet please reconsider. Just because there is osteomyelitis, I argue that does not necessitate amputation.
We all agree that ischemic gangrene and black mummified digits are beyond salvage. That’s not what my concern is. My focus is nonhealing ulcers with underlying osteomyelitis. Whether ischemic in etiology or neuropathic (or both), give salvage a try.
Why is this so important? My opponent will try to convince you that it’s not. He’ll try to sell you on how well people walk after amputation and that functional outcomes are great. But think beyond that for a second.
Amputation changes the foot architecture and weight distribution. In a person with neuropathy, this only predisposes them to more ulcers. More ulcers will mean more infection, which will lead to more amputations. This finally culminates in a major amputation.
In one reported study,1 researchers followed more than 200,000 diabetics from 2010 until 2013. While the risk of amputation overall was relatively small (0.36% for major and 0.56% for minor amputations), prior minor amputation increased the risk of major amputation 10-fold and increased the risk of another minor (below-ankle) amputation 20-fold. Of those who had a major amputation, 57% died over the 3 years. This is not insignificant.
This does not also consider the morbidity and impact on lifestyle and quality of life for these patients. Many may not walk. Some will be relegated to nursing homes. Some will suffer from phantom limb pain. Many may never return to work. Even more will have difficulty with their daily lives, not to mention the psychological recovery also required.
The foot seems to be the only place where amputation as first-line therapy for osteomyelitis is accepted. We don’t do a hip disarticulation for ischial pressure sores with osteomyelitis. Calvarial osteomyelitis is also treated with antibiotics. I implore you: Don’t treat toes like vestigial organs.
Granted, there are subsets of patients who would benefit from amputations. A patient with painful Charcot foot may elect to have a below-knee amputation and move on with life. Another who has lost jobs or significant time due to recurrence of osteomyelitis may progress. A patient with severe sepsis and infection into a joint may need amputation.
But what other treatment options are there? I’m glad you inquired.
I primarily treat diabetic feet by treating the soft tissue envelope. Even if a patient presents with midfoot infection or necrotizing soft tissue infection, I treat it like a good old-fashioned abscess or necrotizing fasciitis:
1) Drain pus
2) Resect the dead stuff
3) Supportive care (antibiotics, fluids, aggressive wound care, etc.)
I try to leave the bones intact. When bone is exposed I take biopsies for culture and pathology. Any bone destroyed by the infection is focally debrided. I also take a specimen of the “bone margin” that I’m leaving behind and I send this to pathology looking for residual acute osteomyelitis. These steps are important as they dictate duration and choice of antibiotic therapy. This is in keeping with the consensus recommendations published in 2016.2
Even chronic wounds get a similar approach. If there is granulation, let it granulate and see if it will fill the wound. “Just because osteomyelitis is there, it doesn’t mean that for the toe we won’t care!”
There are exceptions of course. If the soft tissue is severely affected so the phalynx protrudes like something from the movie “Coco,” probably that should be amputated. Repeat offenders also may progress to amputation. But otherwise, hold off and give it a chance.
For the inpatient, aggressive irrigation of the wounds using the Veraflo system promotes granulation, even for short hospital stays of 1 week or less. Any ischemic component is worked up and addressed with percutaneous or open revascularization. We treat with prolonged antibiotics, and in questionable cases err on the side of giving long-term courses. These wounds need to be offloaded for tasks of daily living (going to the bathroom, making a sandwich, etc.) but otherwise we instruct patients to be effectively non–weight-bearing on that limb.
We also refer patients for hyperbaric therapy frequently. Now if you’re done groaning, I assure you this is not phony medicine. There is growing evidence to support not only improved rates of healing, but also significant cost savings and improved quality of life.3
In young patients or those with large defects, we also involve plastic and reconstructive surgery for secondary closure approaches (free flaps, adjacent tissue transfers, local autogenous or prosthetic grafting [Integra, Stravix, Dermacell, etc.] or other advanced techniques). This is particularly important in plantar wounds that will need to bear weight in the future, or in young patients for improved functional and cosmetic outcomes. For smaller wounds, we often use dermal/subdermal graft substitutes ourselves.
Even still, in nonambulatory or chronically debilitated and medically high-risk patients, maybe a different option is palliative wound care with or without antibiotics. A nonoperative approach to allow individuals to live the rest of their remaining days without undergoing a morbid and disfiguring amputation is not unreasonable. Many families are thankful for this option when given it. In the absence of refractory pain or overwhelming sepsis, we just let the wound do what it will do, understanding that someday the plan may change. This allows patients to continue to treat the wound without escalation to surgery or resorting to amputation.
In the end, just like we vascular surgeons tailor our “holistic” approach to the needs and desires of a single particular patient, we should approach wounds with a similar attitude. The presence of osteomyelitis in and of itself should not prompt one to bypass an entire algorithm, go straight to amputation, do not pass “Go” or “collect $200” (although the professional fee for a toe amputation is probably around $200). With a multidisciplinary and multimodal approach, and vested patients, salvage is possible in the majority of cases.

Amputation: Often the best option
For many years there has been debate about the best management strategy for diabetic foot infection including osteomyelitis. The principles of appropriate antibiotics, surgical debridement, good wound care, and proper offloading will always remain. There are no randomized controlled trials of medical vs. surgical management of diabetic foot ulceration with osteomyelitis.
We now have a number of widely accepted ways to define wounds including Wagner and the SVS-adopted WIFI score. Historical papers are somewhat plagued by heterogeneity in the wounds included. This is even more apparent with any attempted meta-analyses. I think everyone would agree that the superficial toe wound with minimal cellulitis is best managed medically. The issue at hand is the profoundly neuropathic diabetic often with underlying anatomic abnormality and osteomyelitis. My esteemed colleague would suggest that we are too quick to pull a trigger and amputate a toe with underlying osteomyelitis.
I think the initial item for debate is the technique of diagnosis of osteomyelitis. We have multiple ways this is reported. Plain x-ray, bone scan, MRI, and “clinical osteomyelitis” are among the alternative ways osteomyelitis is diagnosed. The reliability of the last is the most variable because clinical osteomyelitis ranges from “probes close to bone” to exposed bone visible protruding from the wound bed. Given the variability of diagnostic techniques, the literature is an amalgam of clinical scenarios and difficult to navigate in a way to affect treatment decisions.
In addition, the medical treatment for osteomyelitis is highly variable. This commonly involves tunneled catheter insertion and 6 weeks to 3 months of IV antibiotics. In some institutions antibiotics are tailored to “wound culture.” Several of our infectious disease specialists prefer bone culture and pathology of bone demonstrating an acute destructive process. Obviously, this often requires surgical debridement to obtain a specimen. Antibiotic duration recommendations may vary from 1 week (if all infected bone is resected) to 90 days if a standalone antibiotic management is selected. Chronic osteomyelitis has a reinfection rate of up to 30%.1
Medical management is not without risk. These risks include recurring infection with resistant organisms, wound deterioration, gastrointestinal complications (Clostridium difficile), catheter-related complications, and acute kidney injury. A recent paper found over 30% of patients treated medically for osteomyelitis developed acute kidney injury. These patients had more frequent hospitalization, recurring ulceration, and infection.2 We have all experienced the patient with multiple hospitalizations and episodic AKI that culminates in ESRD requiring hemodialysis.
If the argument is with good follow-up these patients will ultimately experience preservation of the toe, I would take the stance that in our patient population of diabetics presenting with foot ulcer and osteomyelitis the average hemoglobin A1c is over 9. Although this is not only related to patient compliance, in many instances this is a large piece of the puzzle. It is hard to infer that suddenly with biopsy-proven osteomyelitis the patient will become compliant with medical management of the disease process. Certainly, in some circumstances, this is the case. There are a number of studies with a wide range of findings on HbA1c as it relates to predictive value of wound healing.
There are various studies comparing surgical to medical management for osteomyelitis. Limb salvage is contingent upon location (forefoot, midfoot, hindfoot), the extent of infection, and patient comorbidities. The conclusion of the majority of these studies is that a standalone antibiotic treatment algorithm results in greater limb loss. Patients with peripheral occlusive disease and preadmission antibiotic use have been shown to have decreased wound healing. Minor amputation has been shown to be protective from mortality, risk of major amputation, and unfavorable discharge in patients admitted with a diagnosis of osteomyelitis.3 The major limb amputation rate for antibiotics alone is 20%-30% according to two trials with duration of antibiotics of 3 months.4,5 The available randomized trials tend to exclude patients with severe infection (poorly defined), those with PAD, or those with severe comorbid conditions.
Cost of treatment is even more poorly delineated. Obviously, surgical treatment is not without cost to the health care system. Toe amputation especially when including the metatarsal head shifts pressure points and in the neuropathic patient may lead to recurrent ulceration. The average outpatient cost per patient per ulcer is often over $30,000. The goal of surgical treatment can be defined as trying to maintain the greatest degree of function with the least risk. Removing infected bone (i.e., minor amputation) limits exposure to prolonged antibiotic treatment and hopefully lessens recurring ulceration and hospitalization. This is only one piece of the puzzle, however. A multidisciplinary approach with endocrinology, infectious disease, and orthotics for offloading are keys to decrease future ulceration.
Although I do not advocate for widespread toe carnage as suggested by Dr. Koleilat, I do think liberal application of minor amputation to limit hospital stay, limit antibiotic duration and its inherent risk, and possibly affect readmission is often in the best interest of the patient and the system as a whole. Obviously, based on the variable reports in the literature there cannot be a single approach to these patients and the treatment must be individualized based on extent of infection, compliance of the patient, access to multidisciplinary care, and comorbid conditions.

We treat with prolonged antibiotics, and in questionable cases err on the side of giving long-term courses. These wounds need to be offloaded for tasks of daily living (going to the bathroom, making a sandwich, etc.) but otherwise we instruct patients to be effectively non–weight-bearing on that limb.
We also refer patients for hyperbaric therapy frequently. Now if you’re done groaning, I assure you this is not phony medicine. There is growing evidence to support not only improved rates of healing, but also significant cost savings and improved quality of life.3
In young patients or those with large defects, we also involve plastic and reconstructive surgery for secondary closure approaches (free flaps, adjacent tissue transfers, local autogenous or prosthetic grafting [Integra, Stravix, Dermacell, etc.] or other advanced techniques). This is particularly important in plantar wounds that will need to bear weight in the future, or in young patients for improved functional and cosmetic outcomes. For smaller wounds, we often use dermal/subdermal graft substitutes ourselves.
Even still, in nonambulatory or chronically debilitated and medically high-risk patients, maybe a different option is palliative wound care with or without antibiotics. A nonoperative approach to allow individuals to live the rest of their remaining days without undergoing a morbid and disfiguring amputation is not unreasonable. Many families are thankful for this option when given it. In the absence of refractory pain or overwhelming sepsis, we just let the wound do what it will do, understanding that someday the plan may change. This allows patients to continue to treat the wound without escalation to surgery or resorting to amputation.
In the end, just like we vascular surgeons tailor our “holistic” approach to the needs and desires of a single particular patient, we should approach wounds with a similar attitude. The presence of osteomyelitis in and of itself should not prompt one to bypass an entire algorithm, go straight to amputation, do not pass “Go” or “collect $200” (although the professional fee for a toe amputation is probably around $200). With a multidisciplinary and multimodal approach, and vested patients, salvage is possible in the majority of cases.

Amputation: Often the best option
For many years there has been debate about the best management strategy for diabetic foot infection including osteomyelitis. The principles of appropriate antibiotics, surgical debridement, good wound care, and proper offloading will always remain. There are no randomized controlled trials of medical vs. surgical management of diabetic foot ulceration with osteomyelitis.
We now have a number of widely accepted ways to define wounds including Wagner and the SVS-adopted WIFI score. Historical papers are somewhat plagued by heterogeneity in the wounds included. This is even more apparent with any attempted meta-analyses. I think everyone would agree that the superficial toe wound with minimal cellulitis is best managed medically. The issue at hand is the profoundly neuropathic diabetic often with underlying anatomic abnormality and osteomyelitis. My esteemed colleague would suggest that we are too quick to pull a trigger and amputate a toe with underlying osteomyelitis.
I think the initial item for debate is the technique of diagnosis of osteomyelitis. We have multiple ways this is reported. Plain x-ray, bone scan, MRI, and “clinical osteomyelitis” are among the alternative ways osteomyelitis is diagnosed. The reliability of the last is the most variable because clinical osteomyelitis ranges from “probes close to bone” to exposed bone visible protruding from the wound bed. Given the variability of diagnostic techniques, the literature is an amalgam of clinical scenarios and difficult to navigate in a way to affect treatment decisions.
In addition, the medical treatment for osteomyelitis is highly variable. This commonly involves tunneled catheter insertion and 6 weeks to 3 months of IV antibiotics. In some institutions antibiotics are tailored to “wound culture.” Several of our infectious disease specialists prefer bone culture and pathology of bone demonstrating an acute destructive process. Obviously, this often requires surgical debridement to obtain a specimen. Antibiotic duration recommendations may vary from 1 week (if all infected bone is resected) to 90 days if a standalone antibiotic management is selected. Chronic osteomyelitis has a reinfection rate of up to 30%.1
Medical management is not without risk. These risks include recurring infection with resistant organisms, wound deterioration, gastrointestinal complications (Clostridium difficile), catheter-related complications, and acute kidney injury. A recent paper found over 30% of patients treated medically for osteomyelitis developed acute kidney injury. These patients had more frequent hospitalization, recurring ulceration, and infection.2 We have all experienced the patient with multiple hospitalizations and episodic AKI that culminates in ESRD requiring hemodialysis.
If the argument is with good follow-up these patients will ultimately experience preservation of the toe, I would take the stance that in our patient population of diabetics presenting with foot ulcer and osteomyelitis the average hemoglobin A1c is over 9. Although this is not only related to patient compliance, in many instances this is a large piece of the puzzle. It is hard to infer that suddenly with biopsy-proven osteomyelitis the patient will become compliant with medical management of the disease process. Certainly, in some circumstances, this is the case. There are a number of studies with a wide range of findings on HbA1c as it relates to predictive value of wound healing.
There are various studies comparing surgical to medical management for osteomyelitis. Limb salvage is contingent upon location (forefoot, midfoot, hindfoot), the extent of infection, and patient comorbidities. The conclusion of the majority of these studies is that a standalone antibiotic treatment algorithm results in greater limb loss. Patients with peripheral occlusive disease and preadmission antibiotic use have been shown to have decreased wound healing. Minor amputation has been shown to be protective from mortality, risk of major amputation, and unfavorable discharge in patients admitted with a diagnosis of osteomyelitis.3 The major limb amputation rate for antibiotics alone is 20%-30% according to two trials with duration of antibiotics of 3 months.4,5 The available randomized trials tend to exclude patients with severe infection (poorly defined), those with PAD, or those with severe comorbid conditions.
Cost of treatment is even more poorly delineated. Obviously, surgical treatment is not without cost to the health care system. Toe amputation especially when including the metatarsal head shifts pressure points and in the neuropathic patient may lead to recurrent ulceration. The average outpatient cost per patient per ulcer is often over $30,000. The goal of surgical treatment can be defined as trying to maintain the greatest degree of function with the least risk. Removing infected bone (i.e., minor amputation) limits exposure to prolonged antibiotic treatment and hopefully lessens recurring ulceration and hospitalization. This is only one piece of the puzzle, however. A multidisciplinary approach with endocrinology, infectious disease, and orthotics for offloading are keys to decrease future ulceration.
Although I do not advocate for widespread toe carnage as suggested by Dr. Koleilat, I do think liberal application of minor amputation to limit hospital stay, limit antibiotic duration and its inherent risk, and possibly affect readmission is often in the best interest of the patient and the system as a whole. Obviously, based on the variable reports in the literature there cannot be a single approach to these patients and the treatment must be individualized based on extent of infection, compliance of the patient, access to multidisciplinary care, and comorbid conditions.

Amputation: Resistance is not futile!
What’s in a toe you may ask? Why worry about saving it? Just amputate and move on ...
Not so! I implore you to resist the desire. We vascular surgeons are accustomed to cutting off toes, even feet and legs. But when it comes to diabetic feet please reconsider. Just because there is osteomyelitis, I argue that does not necessitate amputation.
We all agree that ischemic gangrene and black mummified digits are beyond salvage. That’s not what my concern is. My focus is nonhealing ulcers with underlying osteomyelitis. Whether ischemic in etiology or neuropathic (or both), give salvage a try.
Why is this so important? My opponent will try to convince you that it’s not. He’ll try to sell you on how well people walk after amputation and that functional outcomes are great. But think beyond that for a second.
Amputation changes the foot architecture and weight distribution. In a person with neuropathy, this only predisposes them to more ulcers. More ulcers will mean more infection, which will lead to more amputations. This finally culminates in a major amputation.
In one reported study,1 researchers followed more than 200,000 diabetics from 2010 until 2013. While the risk of amputation overall was relatively small (0.36% for major and 0.56% for minor amputations), prior minor amputation increased the risk of major amputation 10-fold and increased the risk of another minor (below-ankle) amputation 20-fold. Of those who had a major amputation, 57% died over the 3 years. This is not insignificant.
This does not also consider the morbidity and impact on lifestyle and quality of life for these patients. Many may not walk. Some will be relegated to nursing homes. Some will suffer from phantom limb pain. Many may never return to work. Even more will have difficulty with their daily lives, not to mention the psychological recovery also required.
The foot seems to be the only place where amputation as first-line therapy for osteomyelitis is accepted. We don’t do a hip disarticulation for ischial pressure sores with osteomyelitis. Calvarial osteomyelitis is also treated with antibiotics. I implore you: Don’t treat toes like vestigial organs.
Granted, there are subsets of patients who would benefit from amputations. A patient with painful Charcot foot may elect to have a below-knee amputation and move on with life. Another who has lost jobs or significant time due to recurrence of osteomyelitis may progress. A patient with severe sepsis and infection into a joint may need amputation.
But what other treatment options are there? I’m glad you inquired.
I primarily treat diabetic feet by treating the soft tissue envelope. Even if a patient presents with midfoot infection or necrotizing soft tissue infection, I treat it like a good old-fashioned abscess or necrotizing fasciitis:
1) Drain pus
2) Resect the dead stuff
3) Supportive care (antibiotics, fluids, aggressive wound care, etc.)
I try to leave the bones intact. When bone is exposed I take biopsies for culture and pathology. Any bone destroyed by the infection is focally debrided. I also take a specimen of the “bone margin” that I’m leaving behind and I send this to pathology looking for residual acute osteomyelitis. These steps are important as they dictate duration and choice of antibiotic therapy. This is in keeping with the consensus recommendations published in 2016.2
Even chronic wounds get a similar approach. If there is granulation, let it granulate and see if it will fill the wound. “Just because osteomyelitis is there, it doesn’t mean that for the toe we won’t care!”
There are exceptions of course. If the soft tissue is severely affected so the phalynx protrudes like something from the movie “Coco,” probably that should be amputated. Repeat offenders also may progress to amputation. But otherwise, hold off and give it a chance.
For the inpatient, aggressive irrigation of the wounds using the Veraflo system promotes granulation, even for short hospital stays of 1 week or less. Any ischemic component is worked up and addressed with percutaneous or open revascularization. We treat with prolonged antibiotics, and in questionable cases err on the side of giving long-term courses.

MVP Data Reveals Gene Mutations Ruling Cholesterol
Using data from the Million Veteran Program (MVP), researchers found people with mutations for PDE3B, PCSK9, and ANGPTL4 had better cholesterol and triglyceride levels than did those without the mutations.
The PDE3B mutation seems to protect against heart disease. A PCSK9 mutation may reduce the risk not only of heart disease, but also abdominal aortic aneurysm. The ANGPTL4 mutation was linked to lower risk of type 2 DM.
MVP, 1 of the world’s largest databases of health and genomic information, partners with veterans receiving care in the VHA to study how genes affect health. It has enrolled > 700,000 veterans to date.

Comorbid depression, anxiety linked to doubled risk of diabetes
Comorbid symptoms of anxiety and depression are associated with twice the risk of developing type 2 diabetes, according to a research paper published in the Journal of Affective Disorders.
The researchers sampled 78,025 Dutch adults aged 30-75 years from the Lifelines Cohort Study and assessed them for depressive and anxious symptoms using the Mini-International Neuropsychiatric Interview before sorting them into groups based on whether they had both, depressive symptoms alone, anxious symptoms alone, or neither.
reported Sonya S. Deschênes, PhD, of the department of psychiatry at McGill University, Montreal, and her associates. Furthermore, in an analysis that adjusted for sociodemographic and lifestyle factors and a family history of diabetes, Dr. Deschênes and her associates found that the participants with both kinds of symptoms had an OR of 1.93 (95% CI, 1.21-3.07) of developing type 2 diabetes. Those with only depressive or anxious symptoms alone did not have a statistically significant risk of developing type 2 diabetes.
A limitation cited by the researchers is that a screening tool was used to assess depressive and anxiety symptoms. Also, glycosylated hemoglobin data were available only for a subset of the participants.
Nevertheless, Dr. Deschênes and her associates wrote, the “study extends ... prior findings and suggests that having co-occurring symptoms of [depression] and anxiety is most strongly associated with an increased risk of [type 2 diabetes]. This study also provides further support for the notion that depression with comorbid anxiety symptoms might represent a group with distinct features.”

Fewer hypos with CGM in routine pediatric T1DM care
BERLIN – A significant reduction in severe hypoglycemia was seen within the first year of using continuous glucose monitoring in a registry study of more than 3,000 children with type 1 diabetes mellitus.
Prior to continuous glucose monitoring (CGM) use, 3.9% of 3,171 individuals, aged a median of 12 years, had hypoglycemia events requiring external help. After 6 months of using CGM, however, the rate of severe hypoglycemia had fallen to 1.2% (P = .10), which remained at 1.2% at 12 months (P = .002). The event rate (events per 100 patient-years) was 10.6 at baseline, 7.8 at 6 months, and 6.1 at 12 months.
Fewer hypoglycemia events leading to coma or convulsion were seen with CGM over time, with 1.3%, 0.6%, and 0.7% of patients reporting at least one event at baseline, 6 months (P = .08), and 12 months (P = .15), respectively. Corresponding event rates were 2.5, 1.6, and 1.7 per 100 patient-years.
“The use of continuous glucose monitoring systems has increased considerably in the past years in individuals with type 1 diabetes,” noted Julia Hermann, a PhD student at Ulm University (Germany), at the annual meeting of the European Association for the Study of Diabetes. “In Germany, for example, CGM use rose considerably when reimbursement by health insurance for CGM started in the summer of 2016.”
Ms. Hermann noted that there were studies showing improved metabolic control with CGM but that clinical studies were often limited by the population of patients studied, restricting treatment to selected patients who may have been adhering better to the use of CGM because they were in a trial.
The aim of the present study was to assess metabolic control and acute complications associated with CGM use in children during its first year of use in a real-world population. Anonymized patient records from the prospective German-Austrian-Luxembourg diabetes patient follow-up (DPV) registry were used.
The DPV database is a standardized, computed-based registry of more than 500,000 adult and pediatric patients with all types of diabetes. It was established in 1995 and receives data from 471 diabetes clinics in Germany, Austria, Luxembourg, and Switzerland.
For the current analysis patients had to be aged under 18 years, have had type 1 diabetes mellitus for at least 1 year, have data available for the months prior to starting CGM, and have at least 1 year of follow-up. For inclusion there also had to be documented use of CMG for at least half of the observation time.
The reduction of severe hypoglycemia observed was not accompanied by any deterioration in metabolic control, Ms. Hermann reported. The median baseline glycosylated hemoglobin (HbA1c) was 7.6% (59 mmol/mol) and this did not noticeably change at either the 6- or 12-month follow-up time point. Furthermore, the percentage of patients achieving a target HbA1c of less than 7.5% was 52% at baseline, 55% at 6 months, and 52% at 12 months.
The rate of diabetic ketoacidosis (DKA), defined as a pH of less than 7.3, also did not change significantly from baseline to the two follow-up points, with event rates of 1.5, 1.4, and 1.1, and the percentage of patients with at least one event being 0.8%, 0.5%, and 0.4%.
“We analyzed an overall well-controlled group of pediatric individuals with type 1 diabetes,” Ms. Hermann said. “We observed a significant reduction of severe hypoglycemia. We observed no improvements in HbA1c, but the overall HbA1c remained stable. We observed no statistically significant change in DKA.”
Future research will try to address some of the limitations that the current data may have, such as looking at a longer follow-up period and other endpoints such as hospitalization, Dr. Hermann suggested. Subgroup analyses are also planned.
“Large databases like the DPV registry ... provide a contemporary picture of diabetes treatment and how the use of diabetes technology has changed over the years and also how diabetes outcomes have improved over the years,” Ms. Hermann said. “It has yet to be seen how most recent changes and advances in diabetes technology will affect these long-term trends.”

BERLIN – A significant reduction in severe hypoglycemia was seen within the first year of using continuous glucose monitoring in a registry study of more than 3,000 children with type 1 diabetes mellitus.
Prior to continuous glucose monitoring (CGM) use, 3.9% of 3,171 individuals, aged a median of 12 years, had hypoglycemia events requiring external help. After 6 months of using CGM, however, the rate of severe hypoglycemia had fallen to 1.2% (P = .10), which remained at 1.2% at 12 months (P = .002). The event rate (events per 100 patient-years) was 10.6 at baseline, 7.8 at 6 months, and 6.1 at 12 months.
Fewer hypoglycemia events leading to coma or convulsion were seen with CGM over time, with 1.3%, 0.6%, and 0.7% of patients reporting at least one event at baseline, 6 months (P = .08), and 12 months (P = .15), respectively. Corresponding event rates were 2.5, 1.6, and 1.7 per 100 patient-years.
“The use of continuous glucose monitoring systems has increased considerably in the past years in individuals with type 1 diabetes,” noted Julia Hermann, a PhD student at Ulm University (Germany), at the annual meeting of the European Association for the Study of Diabetes. “In Germany, for example, CGM use rose considerably when reimbursement by health insurance for CGM started in the summer of 2016.”
Ms. Hermann noted that there were studies showing improved metabolic control with CGM but that clinical studies were often limited by the population of patients studied, restricting treatment to selected patients who may have been adhering better to the use of CGM because they were in a trial.
The aim of the present study was to assess metabolic control and acute complications associated with CGM use in children during its first year of use in a real-world population. Anonymized patient records from the prospective German-Austrian-Luxembourg diabetes patient follow-up (DPV) registry were used.
The DPV database is a standardized, computed-based registry of more than 500,000 adult and pediatric patients with all types of diabetes. It was established in 1995 and receives data from 471 diabetes clinics in Germany, Austria, Luxembourg, and Switzerland.
For the current analysis patients had to be aged under 18 years, have had type 1 diabetes mellitus for at least 1 year, have data available for the months prior to starting CGM, and have at least 1 year of follow-up. For inclusion there also had to be documented use of CMG for at least half of the observation time.
The reduction of severe hypoglycemia observed was not accompanied by any deterioration in metabolic control, Ms. Hermann reported. The median baseline glycosylated hemoglobin (HbA1c) was 7.6% (59 mmol/mol) and this did not noticeably change at either the 6- or 12-month follow-up time point. Furthermore, the percentage of patients achieving a target HbA1c of less than 7.5% was 52% at baseline, 55% at 6 months, and 52% at 12 months.
The rate of diabetic ketoacidosis (DKA), defined as a pH of less than 7.3, also did not change significantly from baseline to the two follow-up points, with event rates of 1.5, 1.4, and 1.1, and the percentage of patients with at least one event being 0.8%, 0.5%, and 0.4%.

Gene Mutation May Lower Cardiometabolic Risk
Researchers from Harvard and Brigham and Women’s Hospital say their study is the first to fully evaluate the link between mutations in sodium glucose co-transporter-1 (SGLT-1)—the gene responsible for absorbing glucose in the gut—and cardiometabolic disease.
The researchers used genetic data from 8,478 participants in the 25-year Atherosclerosis Risk In Communities (ARIC) study. The participants who carried the mutation (6%) had a lower risk of type 2 diabetes, were less obese, had a lower incidence of heart failure, and a lower mortality rate than did those without the mutation, regardless of dietary intake.
The researchers suggest that their findings “open the door to improved therapies” for cardiometabolic diseases.

Nasal glucagon ‘viable alternative’ to intramuscular administration
BERLIN – A dry-powder nasal formulation of glucagon was as good as intramuscular delivery for the reversal of severe hypoglycemia in patients with type 1 diabetes mellitus (T1DM) in a randomized controlled trial.
A 100% treatment success rate (n = 66) was seen for both nasal glucagon and intramuscular glucagon, defined as an increase in plasma glucose to 70 mg/dL (3.9 mmol/L or greater) or more or an increase of 20 mg/L (1.1 mmol/L) or more from the glucose nadir within 30 minutes of administration.
Furthermore, slightly more than 97% of patients achieved treatment success within 15 minutes in both treatment groups, with mean times of 11.4 minutes for the nasal formulation and 9.8 minutes for intramuscular administration.
Similar glucose responses were observed within 40 minutes of glucagon administration, study investigator Leona Plum-Mörschel, MD, PhD, reported at the annual meeting of the European Association for the Study of Diabetes. Dr. Plum-Mörschel is the CEO of the clinical research organization Profil Mainz (Germany), which helped Eli Lilly conduct the trial.
“We are all aware and fully agree that severe hypoglycemia is a serious and potentially life-threatening complication of diabetes treatment with insulin and the sulfonylureas,” said Dr. Plum-Mörschel. At least one in three patients with diabetes reports one hypoglycemic episode per year, she added. While this is quite prevalent in patients with T1DM, it’s not uncommon for those with type 2 diabetes mellitus (T2DM) to experience hypoglycemic episodes.
“Outside of a hospital or emergency room setting, injectable glucagon is currently the only option to treat severe hypoglycemia,” Dr. Plum-Mörschel reminded delegates. “Thankfully, the available injectable glucagon emergency kits are highly effective for the treatment of hypoglycemic events,” she added.
However, for untrained caregivers they can be “really challenging to use,” according to Dr. Plum-Mörschel. This is because the available kits involve multiple steps, including reconstitution, before being ready to inject. A severe hypoglycemic event is stressful enough without them worrying about getting things right, she suggested.
This is where a nasal formulation would be advantageous, and it is something that’s been touted to be on the horizon for a few years. Studies have previously shown that nasal glucagon is comparable to intramuscular glucagon in both adult and pediatric populations. Turning the formulation used in those studies into a commercial product however, has meant more clinical testing before being licensed by the regulatory authorities.
The nasal formulation consists of a dry power containing 3 mg glucagon that is provided in a single-use, compact, and thus, portable, device. It’s been designed to be stored at room temperature and is ready to use immediately. Pressing the plunger on the device releases the fine powder that does not require inhalation to work, which means it can be given easily to an unconscious patient with severe hypoglycemia.
“The aim of the present study was to compare the efficacy and safety of commercially manufactured nasal glucagon with intramuscular glucagon for the treatment of insulin-induced hypoglycemia in adults with type 1 diabetes,” Dr. Plum-Mörschel said.
It was a randomized, single-dose, crossover study involving 70 adult patients with T1DM with hypoglycemia artificially induced by an intravenous insulin infusion during the two dosing visits. Five minutes after stopping insulin, nasal glucagon (3 mg) or intramuscular (1 mg) was given, with multiple plasma glucose measurements taken for up to 90 minutes.
The mean age of participants was 41.7 years old, 61% were male, the mean duration of diabetes was 19.8 years, with a baseline glycated hemoglobin (HbA1c) of 7.3%.
As for safety, Dr. Plum-Mörschel noted that nasal glucagon had a safety profile that was acceptable for emergency treatment. There was no difference between the nasal or intramuscular glucagon treatment groups in the percentages of patients experiencing treatment-emergent adverse events (at least 5% frequency): nausea was seen in 22% and 29%, vomiting in 10% and 12%, and headache in 12% and 7%, respectively.
Asking patients who had been treated with nasal glucagon about specific symptoms related to nasal administration showed around 63% had watery eyes, 49% nasal itching, 39% nasal congestion, 37% a runny nose, 24% sneezing, 20% itchy eyes, and 12.9% itchy throat. “All of these events were transient, generally mild or moderate in nature, and none were serious. Indeed, there were no deaths in the study and no other serious AEs [adverse events] occurred.”
Dr. Plum-Mörschel concluded: “These results support nasal glucagon as a viable alternative to intramuscular glucagon for the treatment of severe hypoglycemia.
“I personally would expect that, due to its simplicity of use, nasal glucagon will create a greater community who can render quick aid in a rescue situation.”
The study was funded by Eli Lilly. Dr. Plum-Mörschel is an employee of Profil Mainz and has received travel grants and speaker honoraria from Eli Lilly and Novo Nordisk.

Transforming glycemic control at Norwalk Hospital
SHM eQUIPS program yields new protocols, guidelines
The Hospitalist recently sat down with Nancy J. Rennert, MD, FACE, FACP, CPHQ, chief of endocrinology and diabetes at Norwalk (Conn.) Hospital, Western Connecticut Health Network, to discuss her institution’s glycemic control initiatives.
Tell us a bit about your program:
Norwalk Hospital is a 366-bed community teaching hospital founded 125 years ago, now part of the growing Western Connecticut Health Network. Our residency and fellowship training programs are affiliated with Yale University, New Haven, Conn., and we are a branch campus of the University of Vermont, Burlington.
With leadership support, we created our Glycemic Care Team (GCT) 4 years ago to focus on improving the quality of care for persons with diabetes who were admitted to our hospital (often for another primary medical reason). Our hospitalists – 8 on the teaching service and 11 on the nonteaching service – are key players in our efforts as they care for the majority of medical inpatients. GCT is interdisciplinary and includes stakeholders at all levels, including quality, pharmacy, nutrition, hospital medicine, diabetes education, administrative leadership, endocrinology, information technology, point-of-care testing/pathology, surgery and more. We meet monthly with an agenda that includes safety events, glucometrics, and discussion of policies and protocols. Subgroups complete tasks in between the monthly meetings, and we bring in other clinical specialties as indicated based on the issues at hand.
What prior challenges did you encounter that led you to enroll in the Glycemic Control (GC) eQUIPS Program?
In order to know if our GCT was making a positive difference, we needed to first measure our baseline metrics and then identify our goals and develop our processes. We wanted actionable data analysis and the ability to differentiate areas of our hospital such as individual clinical units. After researching the options, we chose SHM’s GC eQUIPS Program, which we found to be user friendly. The national benchmarking was an important aspect for us as well. As a kick-off event, I invited Greg Maynard, MD, MHM, a hospitalist and the chief quality officer, UC Davis Medical Center, to speak on inpatient diabetes and was thrilled when he accepted my invitation. This provided an exciting start to our journey with SHM’s eQUIPS data management program.
As we began to obtain baseline measurements of glucose control, we needed a standardized, validated tool. The point-of-care glucose meters generated an enormous amount of data, but we were unable to sort this and analyze it in a meaningful and potentially actionable way. We were especially concerned about hypoglycemia. Our first task was to develop a prescriber ordered and nurse driven hypoglycemia protocol. How would we measure the overall effectiveness and success of the stepwise components of the protocol? The eQUIPS hypoglycemia management report was ideal in that it detailed metrics in stepwise fashion as it related to our protocol. For example, we were able to see the time from detection of hypoglycemia to the next point-of-care glucose check and to resolution of the event.
In addition, we wanted some comparative benchmarking data. The GC eQUIPS Program has a robust database of U.S. hospitals, which helped us define our ultimate goal – to be in the upper quartile of all measures. And we did it! Because of the amazing teamwork and leadership support, we were able to achieve national distinction from SHM as a “Top Performer” hospital for glycemic care.
How did the program help you and the team design your initiatives?
Data are powerful and convincing. We post and report our eQUIPS Glucometrics to our clinical staff monthly by unit, and through this process, we obtain the necessary “buy-ins” as well as participation to design clinical protocols and order sets. For example, we noted that many patients would be placed on “sliding scale”/coverage insulin alone at the time of hospital admission. This often would not be adjusted during the hospital stay. Our data showed that this practice was associated with more glucose fluctuations and hypoglycemia. When we reviewed this with our hospitalists, we achieved consensus and developed basal/bolus correction insulin protocols, which are embedded in the admission care sets. Following use of these order sets, we noted less hypoglycemia (decreased from 5.9% and remains less than 3.6%) and lower glucose variability. With the help of the eQUIPS metrics and benchmarking, we now have more than 20 protocols and safety rules built into our EHR system.
What were the key benefits that the GC eQUIPS Program provided that you were unable to find elsewhere?
The unique features we found most useful are the national benchmarking and “real-world” data presentation. National benchmarking allows us to compare ourselves with other hospitals (we can sort for like hospitals or all hospitals) and to periodically evaluate our processes and reexamine our goals. As part of this program, we can communicate with leaders of other high-performing hospitals and share strategies and challenges as well as discuss successes and failures. The quarterly benchmark webinar is another opportunity to be part of this professional community and we often pick up helpful information.
We particularly like the hyperglycemia/hypoglycemia scatter plots, which demonstrate the practical and important impact of glycemic control. Often there is a see-saw effect in which, if one parameter goes up, the other goes down; finding the sweet spot between hyperglycemia and hypoglycemia is key and clinically important.
Do you have any other comments to share related to your institution’s participation in the program?
We are fortunate to have many successes driven by our participation with the GC eQUIPS Program:
- Coordination of capillary blood glucose (CBG) testing, insulin administration and meal delivery: Use of rapid-acting insulin premeal is standard of care and requires that CBG testing, insulin, and meal delivery be precisely coordinated for optimal insulin action. We developed a process in which the catering associate calls the nurse using a voice-activated pager when the meal tray leaves the kitchen. Then, the nurse checks the CBG and gives insulin when the tray arrives. The tray contains a card to empower the patient to wait for the nurse to administer insulin prior to eating. This also provides an opportunity for nutritional education and carbohydrate awareness. Implementation of this process increased the percentage of patients who had a CBG and insulin administration within 15 minutes before a meal from less than 10% to more than 60%.
- Patient education regarding insulin use: In many cases, hospital patients may be started on insulin and their oral agents may be discontinued. This can be confusing and frightening to patients who often do not know if they will need to be on insulin long term. Our GCT created a script for the staff nurse to inform and reassure patients that this is standard practice and does not mean that they will need to remain on insulin after hospital discharge. The clinical team will communicate with the patient and together they will review treatment options. We have received many positive reviews from patients and staff for improving communication around this aspect of insulin therapy.
- Clinician and leader education: When our data revealed an uptick in hypoglycemia in our critical care units, we engaged the physicians, nurses, and staff and reviewed patient charts to identify potential process changes. To keep hypoglycemia in the spotlight, our director of critical care added hypoglycemia to the ICU checklist, which is discussed on all team clinical rounds. We are also developing an electronic metric (24-hour glucose maximum and minimum values) that can be quickly reviewed by the clinical team daily.
- Hypoglycemia and hyperkalemia: Analysis of our hypoglycemia data revealed a higher-than-expected rate in the ED in patients who did not have a diabetes diagnosis. Further review showed that this was associated with insulin treatment of hyperkalemia. Subsequently, we engaged our resident trainees and other team members in a study to characterize this hypoglycemia-hyperkalemia, and we have recently submitted a manuscript for publication detailing our findings and recommendations for glucose monitoring in these patients.
- Guideline for medical consultation on nonmedical services: Based on review of glucometrics on the nonmedical units and discussions with our hospitalist teams, we designed a guideline that includes recommendations for Medical Consultation in Nonmedical Admissions. Comanagement by a medical consultant will be requested earlier, and we will monitor if this influences glucometrics, patient and hospitalist satisfaction, etc.
- Medical student and house staff education: Two of our GCT hospitalists organize a monthly patient safety conference. After the students and trainees are asked to propose actionable solutions, the hospitalists discuss proposals generated at our GCT meetings. The students and trainees have the opportunity to participate in quality improvement, and we get great ideas from them as well.
Perhaps our biggest success is our Glycemic Care Team itself. We now receive questions and items to review from all departments and are seen as the hospital’s expert team on diabetes and hyperglycemia. It is truly a pleasure to lead this group of extremely high functioning and dedicated professionals. It is said that “team work makes the dream work.” Moving forward, I hope to expand our Glycemic Care Team to all the hospitals in our network.

SHM eQUIPS program yields new protocols, guidelines
The Hospitalist recently sat down with Nancy J. Rennert, MD, FACE, FACP, CPHQ, chief of endocrinology and diabetes at Norwalk (Conn.) Hospital, Western Connecticut Health Network, to discuss her institution’s glycemic control initiatives.
Tell us a bit about your program:
Norwalk Hospital is a 366-bed community teaching hospital founded 125 years ago, now part of the growing Western Connecticut Health Network. Our residency and fellowship training programs are affiliated with Yale University, New Haven, Conn., and we are a branch campus of the University of Vermont, Burlington.
With leadership support, we created our Glycemic Care Team (GCT) 4 years ago to focus on improving the quality of care for persons with diabetes who were admitted to our hospital (often for another primary medical reason). Our hospitalists – 8 on the teaching service and 11 on the nonteaching service – are key players in our efforts as they care for the majority of medical inpatients. GCT is interdisciplinary and includes stakeholders at all levels, including quality, pharmacy, nutrition, hospital medicine, diabetes education, administrative leadership, endocrinology, information technology, point-of-care testing/pathology, surgery and more. We meet monthly with an agenda that includes safety events, glucometrics, and discussion of policies and protocols. Subgroups complete tasks in between the monthly meetings, and we bring in other clinical specialties as indicated based on the issues at hand.
What prior challenges did you encounter that led you to enroll in the Glycemic Control (GC) eQUIPS Program?
In order to know if our GCT was making a positive difference, we needed to first measure our baseline metrics and then identify our goals and develop our processes. We wanted actionable data analysis and the ability to differentiate areas of our hospital such as individual clinical units. After researching the options, we chose SHM’s GC eQUIPS Program, which we found to be user friendly. The national benchmarking was an important aspect for us as well. As a kick-off event, I invited Greg Maynard, MD, MHM, a hospitalist and the chief quality officer, UC Davis Medical Center, to speak on inpatient diabetes and was thrilled when he accepted my invitation. This provided an exciting start to our journey with SHM’s eQUIPS data management program.
As we began to obtain baseline measurements of glucose control, we needed a standardized, validated tool. The point-of-care glucose meters generated an enormous amount of data, but we were unable to sort this and analyze it in a meaningful and potentially actionable way. We were especially concerned about hypoglycemia. Our first task was to develop a prescriber ordered and nurse driven hypoglycemia protocol. How would we measure the overall effectiveness and success of the stepwise components of the protocol? The eQUIPS hypoglycemia management report was ideal in that it detailed metrics in stepwise fashion as it related to our protocol. For example, we were able to see the time from detection of hypoglycemia to the next point-of-care glucose check and to resolution of the event.
In addition, we wanted some comparative benchmarking data. The GC eQUIPS Program has a robust database of U.S. hospitals, which helped us define our ultimate goal – to be in the upper quartile of all measures. And we did it! Because of the amazing teamwork and leadership support, we were able to achieve national distinction from SHM as a “Top Performer” hospital for glycemic care.
How did the program help you and the team design your initiatives?
Data are powerful and convincing. We post and report our eQUIPS Glucometrics to our clinical staff monthly by unit, and through this process, we obtain the necessary “buy-ins” as well as participation to design clinical protocols and order sets. For example, we noted that many patients would be placed on “sliding scale”/coverage insulin alone at the time of hospital admission. This often would not be adjusted during the hospital stay. Our data showed that this practice was associated with more glucose fluctuations and hypoglycemia. When we reviewed this with our hospitalists, we achieved consensus and developed basal/bolus correction insulin protocols, which are embedded in the admission care sets. Following use of these order sets, we noted less hypoglycemia (decreased from 5.9% and remains less than 3.6%) and lower glucose variability. With the help of the eQUIPS metrics and benchmarking, we now have more than 20 protocols and safety rules built into our EHR system.
What were the key benefits that the GC eQUIPS Program provided that you were unable to find elsewhere?
The unique features we found most useful are the national benchmarking and “real-world” data presentation. National benchmarking allows us to compare ourselves with other hospitals (we can sort for like hospitals or all hospitals) and to periodically evaluate our processes and reexamine our goals. As part of this program, we can communicate with leaders of other high-performing hospitals and share strategies and challenges as well as discuss successes and failures. The quarterly benchmark webinar is another opportunity to be part of this professional community and we often pick up helpful information.
We particularly like the hyperglycemia/hypoglycemia scatter plots, which demonstrate the practical and important impact of glycemic control. Often there is a see-saw effect in which, if one parameter goes up, the other goes down; finding the sweet spot between hyperglycemia and hypoglycemia is key and clinically important.
Do you have any other comments to share related to your institution’s participation in the program?
