Type 1 Diabetes: Research for Pancreatic Replacement, Transplantation and Regeneration

By Karin Katz, MD

In 1964, Dr. Arnold Kadish used real-time glucose monitoring to adjust insulin infusion in a patient with diabetes and introduced the concept of a closed-loop system of insulin delivery. A decade later, several research groups developed closed-loop systems that linked glucose monitors with insulin pumps and determined how much insulin to deliver based on calculations from a set of algorithms .  These big, bulky machines depended on intravenous routes of glucose sensing and insulin infusion. While the…

Down-And-Out With Diabetes: Caring For The Homeless Diabetic Patient

By Sara Gallant

Each year in the US, an estimated 2.3–3.5 million individuals are homeless . Homelessness has a complicated association with poor health. People at risk for losing their home tend to have heavier disease burdens. In New York City, 6.3% of a subset of newly homeless people had diabetes mellitus, compared to 1.9% of the same age group in the general US population . In return, homelessness poses unique challenges to receiving and adhering to treatment for diabetes. The rewards…

Is There Evidence to Support a Vegetarian Diet in Common Chronic Diseases?

By Christopher Graffeo

Faculty Peer Reviewed

In the age of prevention, primary care is more empowered than ever to educate patients on reducing their risk for common chronic diseases by promoting behavior modifications early in the natural history. In the clinic, this means a focus on hyperlipidemia, hypertension, and diabetes—risk factors that play synergistic roles in causing a wide array of diseases with tremendous morbidity and mortality. Given the large number of risk factors that co-exist for so many patients, astute clinicians are aiming for…

Should I Add Sugar or Splenda to My Coffee?

By Reda Issa

Faculty Peer Reviewed

As a medical student, I adjusted to waking up at 6 AM every day – with the help of coffee, of course. Living in New York City and its fast-paced routine requires that extra kick those beans provide. So, should I add sugar or Splenda to my coffee? Half a century ago this question did not exist, but obesity was not a word in the Merriam-Webster then. Today, we have to think more carefully.

Non-sucrose based sweeteners can be…

Too Much of a Good Thing: The Evidence Behind the Need for a Bisphosphonate Holiday

By Jenna Piccininni

Faculty Peer Reviewed

Bisphosphonates are a relatively new medication having only been approved to treat osteoporosis in the US since 1995 . In addition, large placebo controlled trials have, at most, 10 years of follow-up data. Thus, there are still questions regarding the long-term use of these agents. There are a few well-established side effects of bisphosphonates including rare osteonecrosis of the jaw and more common esophageal irritation. However, several more recent case reports suggest a correlation between prolonged bisphosphonate use and…

The Effect of Bariatric Surgery on Incretin Hormones and Glucose Homeostasis

By Michael Crist

Faculty Peer Reviewed

Until recently, little thought was given to the important role played by the duodenum, jejunum, and ileum in glucose homeostasis. The involvement of the gut in glucose regulation is mediated by the enteroinsular axis, which refers to the neural and hormonal signaling pathways that connect the gastrointestinal (GI) tract with pancreatic beta cells. These pathways are largely responsible for the increase in insulin that occurs during the postprandial period. In 1964 McIntyre and colleagues first reported the phenomenon…

White Coat Hypertension: Are Doctors Bad for Your Blood Pressure?

By Lauren Foster

Faculty Peer Reviewed

Hypertension is a pervasive chronic disease affecting approximately 65 million adults in the United States, and a significant cause of morbidity and mortality . Antihypertensives are widely prescribed due to their effectiveness in lowering blood pressure, thereby reducing the risk of cardiovascular events. However, the phenomenon of the “white coat effect” may be a complicating factor in the diagnosis and management of hypertensive patients. It is well established that a considerable number of people experience an elevation of their…

What Is Andropause?  Is Testosterone Supplementation the Answer in Older Men?

By Kylie Birnbaum

Faculty Peer Reviewed

Women have long bemoaned menopause and its physiological, psychological, and sexual effects. Fortunately, hormone replacement therapy has provided relief for symptomatic women. Less attention is paid to men, who also experience declines in their sex hormones. Decreased testosterone may explain many symptoms experienced by elderly men, such as poor sexual function and libido, decreased bone mineral density, fatigue, and decreased muscle mass and strength. Should physicians treat elderly men with testosterone replacement therapy?

Late-onset hypogonadism, or “andropause,” is the…

Introduction

Few people these days are unaware of the “obesity epidemic,” with its inception here in the United States and its steady, insidious spread around the globe. The numbers are truly staggering: in 2008, the World Health Organization estimated that 1.5 billion adults–over 20% of the earth’s population–were overweight, and 500 million of those were classified as obese, with a body mass index greater than 30. In the United States, over a third of the population is overweight, and…

When Is Hemoglobin A1c Inaccurate In Assessing Glycemic Control?

By Joseph Larese

Faculty Peer Reviewed

Hemoglobin A1C (HbA1c) is an invaluable tool for monitoring long-term glycemic control in diabetic patients. However, many clinicians managing diabetics have encountered the problem of HbA1c values that do not agree with fingerstick glucose logs. Before suspecting an improperly calibrated glucometer or poor patient record keeping, it is useful to consider the situations in which HbA1c may be spuriously elevated or depressed. These issues are best understood after reviewing how HbA1c is defined and measured–topics fraught with considerable confusion.…
