Endocrinology practice patterns of hypothyroidism and osteoporosis management in a U.S. tertiary academic medical center.

Background: The major published clinical guidelines for the management of hypothyroidism and osteoporosis are not uniformly consistent and may be a significant contributor to variability of clinical care delivered by endocrinologists, in addition to other factors, such as physician experience, physician and patient perceptions, and patient comorbidities. The purpose of this study was to assess practice patterns of hypothyroidism and osteoporosis within an academic endocrine clinic.

Methods: A retrospective medical record review of the first 200 adult patients ( = 100 with primary hypothyroidism and  = 100 with osteoporosis or osteopenia) seen by an endocrinologist beginning January 2, 2017at a large U.

Spontaneous Regression of Metastatic Papillary Thyroid Cancer in a Lymph Node.

Spontaneous regression of cancer is defined as disappearance of cancer in the absence of specific therapy. In thyroid cancer patients with biochemically incomplete response to initial treatments, spontaneous decline in thyroglobulin levels without any cancer treatment is a well-known phenomenon; however, spontaneous regression of persistent or recurrent structural disease has not been reported. We here present a case of papillary thyroid cancer in a 58-year-old female who underwent total thyroidectomy and two radioiodine ablations.

Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D.

Fatty acid transport protein 4 is dispensable for intestinal lipid absorption in mice.

FA transport protein 4 (FATP4), one member of a multigene family of FA transporters, was proposed as a major FA transporter in intestinal lipid absorption. Due to the fact that Fatp4(-/-) mice die because of a perinatal skin defect, we rescued the skin phenotype using an FATP4 transgene driven by a keratinocyte-specific promoter (Fatp4(-/-);Ivl-Fatp4(tg/+) mice) to elucidate the role of intestinal FATP4 in dietary lipid absorption. Fatp4(-/-);Ivl-Fatp4(tg/+) mice and wild-type littermates displayed indistinguishable food consumption, growth, and weight gain on either low or high fat (Western) diets, with no differences in intestinal triglyceride (TG) absorption or fecal fat losses.
