Diabetes Core Update – February 2014

Podcast by the American Diabetes Association
Hosts: Dr. Neil Skolnik & Dr. John J. Russell
Date: January 19, 2014
Episode Theme:
This episode covers the latest research from ADA journals relevant to diabetes clinical practice, highlighting six recent articles. The focus is on evidence relating to lifestyle factors, treatment intensification, and associated health risks in both adults and youth with (pre)diabetes.

Key Discussion Points & Insights

1. Coffee Consumption and Type 2 Diabetes Risk

Source: Diabetes Care (February 2014)
Summary:

• Large meta-analysis: 28 prospective studies, 1.1 million participants, >45,000 cases of type 2 diabetes (T2DM), with follow-up ranging 10 months–20 years.
• A graded, inverse relationship between coffee intake and risk of T2DM.
  • 1 cup/day: RR 0.92 (8% decrease)
  • 6 cups/day: RR 0.67 (33% decrease)
• No difference between caffeinated vs. decaf coffee. Memorable Quote:

“Compared with no or rare coffee consumption, the relative risk of developing diabetes in people drinking one cup of coffee a day was 0.92... and that was a graded risk...”
— Dr. Neil Skolnik (01:15)

Discussion:

• Dr. Russell speculates reasons for outcomes, including coffee replacing sugary beverages, and the general popularity of coffee in the US.
  • He notes coffee is not “completely protective” given current US diabetes rates.
• Fun Fact: Starbucks' original name was almost "Pequod," a Moby Dick reference.

2. Fitness, Fatness and Survival in Prediabetes

Source: Diabetes Care (February 2014)
Summary:

• Large cohort (17,000+, 89% men, prediabetes defined by FBS 100–125 mg/dL).
• 14-year follow-up: 832 deaths.
• Main finding: Cardiorespiratory fitness more strongly linked to lower all-cause and cardiovascular mortality than BMI.
  • Unfit normal-weight: higher all-cause mortality (HR 1.7)
  • Fit overweight or obese: similar mortality to fit normal-weight individuals. Memorable Quote:

“If you’re fit, even if you're overweight, fit, overweight people do better than unfit people who are normal weight...”
— Dr. Neil Skolnik (05:53)

Discussion:

• Emphasis on promoting achievable fitness goals over weight alone for metabolic and mortality benefits. Timestamps: [02:56 – 05:45]

3. Severe Hypoglycemia and Cognitive Decline in Older Adults with Type 2 Diabetes

Source: Diabetes Care (February 2014, Scottish study)
Summary:

• 831 adults, ages 60–75, 4-year follow-up.
• 9% with baseline hypoglycemia history; 10% experienced incident hypoglycemia.
• Both prior and new-onset hypoglycemia were associated with greater cognitive decline, even after adjusting for comorbidities. Memorable Quote:

“Incident hypoglycemia was associated with poor cognitive ability at baseline... both history and incident hypoglycemia were associated with greater cognitive decline.”
— Dr. Neal Skolnik (07:39)

Discussion:

• Chicken-and-egg dilemma: Is hypoglycemia causing cognitive decline, or vice versa?
• Importance of individualizing A1C targets and avoiding overtreatment in elderly patients. Notable Guidance:

“If someone is starting to have cognitive decline, does it really matter that their blood sugar control was quite as tight?”
— Dr. John Russell (09:23) Timestamps: [05:46 – 11:56]

4. Intensification of Insulin Regimens in T2DM: Premixed vs. Basal Plus Bolus Therapy

Source: Diabetes Care (February 2014)
Summary:

• Open-label, one-year randomized trial: premixed insulin vs. basal + mealtime insulin in adults with low-calorie breakfast intake.
• Both strategies dropped A1C from ~9% to ~7.4%.
• Premixed insulin: more patients reached A1C <7% (48% vs. 36%) compared to basal group.
• No significant differences in hypoglycemia, weight, or insulin dose. Memorable Quote:

“The take home point here is that there are lots of choices... the important take home point is to choose one of them…”
— Dr. Neal Skolnik (13:10)

Discussion:

• Both regimens are viable—decision should be individualized.
• Primary care practices need confidence in actual insulin titration steps after basal failure. Timestamps: [11:57 – 14:15]

5. Obstructive Sleep Apnea (OSA), REM Sleep, and Glycemic Control

Source: Diabetes Care (February 2014)
Summary:

• 115 participants underwent polysomnography and A1C testing.
• REM sleep apnea events (not non-REM) strongly linked to increasing A1C.
• Mean A1C: 6.3% (lowest REM AHI) vs. 7.3% (highest REM AHI). Memorable Quote:

“REM apnea hypopnea index was independently associated with increasing levels of A1C.”
— Dr. Neal Skolnik (14:20)

Discussion:

• OSA increases diabetes and hypertension risk via neuroendocrine mechanisms.
• CPAP therapy may improve glycemic control.
• Bariatric surgery helps, but not universally—25% may see no OSA improvement.
• Level of OSA resolution correlates with the extensiveness of bariatric procedure. Timestamps: [14:16 – 17:20]

6. Lifestyle Intervention in Obese Youth with Prediabetes ("Bright Bodies" Program)

Source: Diabetes Care (February 2014)
Summary:

• RCT: intensive lifestyle (exercise, nutrition, behavior modification) vs. standard care in obese youth (10–16 yrs) with prediabetes.
• Six months: “Bright Bodies” group saw greater reduction in 2-hour OGTT glucose and higher conversion to normoglycemia.
  • 27% improvement with intervention vs. 10% with standard care.
• Racially/ethnically diverse population; potential for lasting behavioral change seeded early in life. Memorable Quote:

“Over only six months, we see a decrease in two hour postprandials... 27% versus negative 10... and what's exciting about this is often habits that are developed in youth are habits which are carried over into adulthood.”
— Dr. Neal Skolnik (19:23)

Discussion:

• Early, intensive intervention pays off.
• Strong parallels with adult DPP findings; huge implications for the obesity and youth T2DM epidemic. Timestamps: [17:21 – 20:18]

Notable Quotes & Moments

Coffee & Diabetes

• “I would not have guessed that caffeinated part... it's a dose response. So if I'm drinking more hot beverage... I'm less likely to have diabetes.”
  — Dr. John Russell (02:11)

Fitness vs. Weight

• “If you have to pick one thing to work on, it's cardiorespiratory fitness.”
  — Dr. Neil Skolnik (06:10)

Cognitive Decline & Hypoglycemia

• “Is the juice worth the squeeze? If someone is starting to have cognitive decline, does it really matter that their blood sugar control was quite as tight?”
  — Dr. John Russell (09:17)

Insulin Regimens

• “We're not always that good when someone's A1C is still uncontrolled on basal insulin alone about knowing what to do next.”
  — Dr. Neal Skolnik (12:24)

Sleep Apnea’s Reach

• “Needs to be something on our differential diagnosis for someone with secondary causes of hypertension... neuroendocrine level that is increasing people's blood sugars...”
  — Dr. John Russell (15:03)

Structure & Flow

• Each article is introduced briefly by Dr. Skolnik.
• Dr. Russell offers contextualization and clinical/practical insights.
• Both hosts underscore practical take-home points for each topic.
• The tone is conversational, evidence-based, and oriented toward clinical application.
• The episode moves briskly through six topics, illustrating direct relevance of new research to patient care, with healthy skepticism and anecdotes that add color and context.
