Insulin therapy for the treatment of type 1 diabetes during pregnancy

The Journal of Maternal-Fetal & Neonatal Medicine

M. James Lenhard & Brendan T. Kinsley


Pregnancies affected by type 1 diabetes (T1D) carry a major risk for poor fetal, neonatal and maternal outcomes. Achieving normoglycemia while minimizing the risk of hypoglycemia is a major goal in the management of T1D as this can greatly reduce the risk of complications. However, maintaining optimal glucose levels is challenging because insulin requirements are not uniform throughout the course of the pregnancy.

Effects of surgically induced weight loss by Roux-en-Y gastric bypass on cardiovascular autonomic nerve function

Surgery for Obesity and Related Diseases

Maser, Raelene E., M. James Lenhard, Michael B. Peters, Isaias Irgau, and Gail M. Wynn


Obesity is associated with autonomic imbalance. With respect to cardiovascular autonomic dysfunction, this is characterized by reduced heart rate variability (HRV). Our objective was to determine the effect of surgically induced weight loss on cardiovascular autonomic nerve fiber function in subjects with severe obesity and examine whether an association with reduced insulin resistance exists. The setting was a hospital and private practice in the United States.

Hip Strength in Adults With Type 1 Diabetes is Associated With Age at Onset of Diabetes

Journal of Clinical Densitometry

Maser, Raelene E., Paul Kolm, Christopher M. Modlesky, Thomas J. Beck, and M. James Lenhard


We investigated the association of age at onset of type 1 diabetes with areal bone mineral density (aBMD), estimates of bone strength, and outer diameter. Using dual-energy X-ray absorptiometry (DXA), aBMD, axial strength (cross-sectional area [CSA]), bending strength (section modulus [SM]), and outer diameter at the narrow neck, intertrochanter, and shaft of the proximal femur were determined for 60 adults.

Autonomic nerve fiber function and bone mineral density in individuals with type 1 diabetes: A cross-sectional study

Diabetes Research and Clinical Practice

Raelene E. Maser, John N. Stabley, M. James Lenhard, Michelle A. Provost-Craig


Experimental models support a role for the sympathetic nervous system in bone metabolism. Beta-adrenoreceptors have been demonstrated on osteoblast-like cells. Beta-blocker use is associated with higher bone mineral density (BMD) in some epidemiologic studies. The aim of this study was to determine if measures of the autonomic nervous system (ANS) were associated with reduced BMD in type 1 diabetes.
