MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Childhood obesity is becoming an emerging public health issue worldwide, owing to its association with a variety of health problems at younger ages in adulthood, including obesity, type 2 diabetes and cardiovascular diseases. Identification of prenatal and early life risk factors is key for curbing the epidemic of the childhood obesity.

Main finding of the present study is that among pregnant women, elevated blood pressure is associated with a greater risk of overweight and obesity for their children.

MedicalResearch.com: What is the background for this study?

Response: Polycystic ovary syndrome (PCOS) is a common endocrine disorder. PCOS is most often defined according to the Rotterdam criteria, which include irregular ovulation, biochemical/clinical hyperandrogenism, and/or polycystic ovaries when other etiologies are excluded. PCOS is associated with insulin resistance and obesity, but data regarding development and risk factors for type 2 diabetes (T2D) in PCOS are limited.

We performed a National Register-based study on Danish women with PCOS and included data regarding T2D events according to diagnosis codes and filled medicine prescriptions (N=18,477). Three age-matched controls were included per patient (N=54,680).

MedicalResearch.com: What are the main findings?

Response: We found that the risk for development of type 2 diabetes was 4 times increased in women with PCOS compared to controls. The median age at diagnosis of  type 2 diabetes was 31 years in women with PCOS compared with 35 years in controls suggesting that T2D was diagnosed 4 years earlier in PCOS. Increasing body mass index was associated with increased risk of development of T2D, whereas higher number of births was negatively associated with development of type 2 diabetes.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Further studies are needed regarding predictors of  type 2 diabetes in PCOS. Our data support a considerable increased risk for type 2 diabetes in obese women with PCOS.

Risks of Surgery For Thyroid Cancer Higher Than Expected

MedicalResearch.com Interview with:

Megan Rist Haymart MD Assistant Professor University of Michigan

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Thyroid cancer is typically treated with thyroid surgery. It is common practice for physicians to inform patients that the risk of vocal cord paralysis or hypoparathyroidism with thyroid surgery is 1-3%.

However, most of these estimates are based on single institution studies with high volume surgeons. In our study we evaluated surgical risks in a population-based cohort. Using the Surveillance, Epidemiology, and End Results-Medicare database, we found that 6.5% of thyroid cancer patients developed general post-operative complications (fever, infection, hematoma, cardiopulmonary and thromboembolic events) and 12.3% developed thyroid surgery specific complications (hypoparathyroidism/hypocalcemia, vocal cord/fold paralysis).

Older patient age, presence of comorbidities, and advanced stage disease were associated with the greatest risks of surgical complications.

Bisphenol A May Promote Obesity By Interfering with Leptin Early in Life

MedicalResearch.com Interview with:
Alfonso Abizaid PhD

Department of Neuroscience
Carleton University

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Bisphenol A (BPA) is a compound considered to be a potential environmental hazard and an endocrine disruptor. We have found an association between exposure to BPA at levels that are considered safe by Health Canada and the EPA early in life, and the development of obesity. In addition, we found that this propensity to develop obesity is due to under development of the hypothalamic projection field of POMC neurons, a set of neurons that regulate satiety and stimulate metabolic rate.

In this paper we replicate those findings and also show that this abnormal development is due to BPA altering the secretion of the hormone leptin at critical times where this hormone is important for the post-natal development of these POMC neurons.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The potential role of gut inflammation and microbiome is becoming a hot topic in the field of diabetes. Several very recent publications report the presence of intestinal abnormalities associated with autoimmune diabetes in both experimental rodent models and patients. We have previously published that, compared to healthy subjects, patients with type 1 diabetes or at high risk of developing type 1 diabetes shows increased intestinal permeability.

Among the factors that may modify the intestinal barrier and impact on its immune activation, the gut microbiota is at present the main suspect. Our study is the first in literature that had the opportunity to analyze the inflammatory profile, the microbiome and their correlation on duodenum biopsies of patients with type 1 diabetes, in comparison with patients with celiac disease and healthy controls. Previous papers pointed out a significant difference in the composition of the stool microflora in subjects with autoimmune diabetes.

A major advancement of our work comes from the direct analysis of small intestine, instead of studies on stool samples. In fact, because of their close functional and spatial relationships, as well as a shared blood supply, it is logical to consider the duodenum and the pancreas correlated. We found big differences among the groups: gut mucosa in diabetes shows a peculiar signature of inflammation, a specific microbiome composition and we also discovered a strong association between some analysed inflammatory markers and specific bacteria genera. We think that our data add an important piece to disentangle the complex pathogenesis of type 1 diabetes and more generally of autoimmune diseases.

MedicalResearch.com: What is the background for this study?

Response: This study was mainly motivated by the absence of available data on the effect of menopausal hormone therapy (MHT) on bone microarchitecture, as well as contradictory results of previous trials regarding the persistence of a residual effect after MHT withdrawal.

We performed a cross-sectional analysis of 1279 postmenopausal women aged 50-80 years participating in OsteoLaus cohort of Lausanne University Hospital. Participants had bone mineral density (BMD) measurement by dual X-ray absorptiometry (DXA) at lumbar spine, femoral neck and total hip, as well as assessment of trabecular bone score (TBS), a textural index that evaluates pixel grey-level variations in the lumbar spine DXA image, providing an indirect index of trabecular microarchitecture.

Antonio C. Bianco, MD, PhD Rush University Medical Center

Dr. Antonio C. Bianco

Antonio C. Bianco, MD, PhD
Rush University Medical Center

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The standard of care for patients with hypothyroidism is treatment with levothyroxine. The dosage of levothyroxine is adjusted for each patient with the goal of normalizing blood levels of TSH. About 15% of the patients treated this way exhibit variable degrees of residual symptoms, despite having a normal TSH level. These symptoms include difficulty losing weight, low energy and depression. However, given the subjective nature of these complains and that the blood levels of TSH are normal, many times such symptoms are dismissed by physicians as non-thyroid related.
