Article Synopsis
  • Menstrually related mood disorder (MRMD) is characterized by severe emotional symptoms occurring in the late luteal phase of the menstrual cycle, which may be linked to low levels of the neuroactive steroid allopregnanolone due to lesser conversion from progesterone.
  • In a study with nine women with MRMD and fourteen healthy controls, MRMD was diagnosed using the DSM-5 criteria, and symptoms of depression and anxiety, as well as plasma neuroactive steroid levels, were assessed at different phases of the menstrual cycle.
  • Results showed that while women with MRMD had higher allopregnanolone levels in the mid-follicular phase, they experienced greater depression severity only in the late luteal phase, suggesting a

Article Synopsis
  • * Researchers used advanced LC-MS/MS assays to test whether higher serum myostatin levels correlate with lower insulin sensitivity in 74 overweight/obese adults aged 20-65 without type 2 diabetes.
  • * The findings revealed that higher serum myostatin levels were linked to lower insulin sensitivity (Matsuda index) even after accounting for factors like BMI and sex, suggesting myostatin might play a role in the development of insulin resistance.

Article Synopsis
  • Overweight and obesity are linked to a deficiency in growth hormone (GH), which contributes to nonalcoholic fatty liver disease (NAFLD), a condition with limited treatment options.
  • Researchers conducted a 6-month trial where 53 adults with NAFLD were randomly assigned to receive either low-dose GH or a placebo, focusing on reducing fat in the liver.
  • Results showed that GH administration significantly decreased liver fat more than the placebo, without negatively affecting blood sugar levels, suggesting GH could be a potential treatment for NAFLD.

Objective: Anorexia nervosa is associated with low bone mineral density (BMD) and deficits in bone microarchitecture and strength. Low BMD is common in atypical anorexia nervosa, in which criteria for anorexia nervosa are met except for low weight. We investigated whether women with atypical anorexia nervosa have deficits in bone microarchitecture and estimated strength at the peripheral skeleton.

Objective: Anorexia nervosa is complicated by high bone resorption, low bone mineral density (BMD), and increased fracture risk. We investigated whether off-label antiresorptive therapy with denosumab increases BMD in women with anorexia nervosa.

Design: Twelve-month, randomized, double-blind, placebo-controlled study.

Context: Obesity is a state of relative growth hormone (GH) deficiency, and GH has been identified as a candidate disease-modifying target in nonalcoholic fatty liver disease (NAFLD) because of its lipolytic and anti-inflammatory properties. However, the GH/IGF-1 axis has not been well characterized in NAFLD.

Objective: We aimed to investigate serum GH and IGF-1 levels in relation to intrahepatic lipid content (IHL) and markers of hepatocellular damage and fibrosis in NAFLD.

Objective: Anorexia nervosa (AN) is a serious condition characterized by undernutrition, complicated by endocrine dysregulation, and with few predictors of recovery. Urinary free cortisol (UFC) is a predictor of weight gain, but 24-h urine samples are challenging to collect. We hypothesized that serum dehydroepiandrosterone sulfate (DHEAS), which like cortisol is regulated by adrenocorticotropic hormone (ACTH), would predict weight gain and increases in fat mass in women with AN.

Purpose: Rates of vitamin D deficiency and nutritional rickets have been rising over the past several decades, particularly in high-risk infants. This pilot study assessed the impact of providing free vitamin D supplements, a culturally-appropriate educational brochure, and a brief counseling session about the importance of both vitamin D supplementation and breastfeeding to the parents of Somali infants at routine office visits from newborn through 6 months of age at three Federally Qualified Health Centers in Colorado. We also assessed the impact this intervention had on rates of breastfeeding.

Purpose: To assess long-term quality of life (QoL) in patients with sustained biochemical control of acromegaly, comparing those receiving vs not receiving pharmacotherapy (primary analysis); to assess change in QoL over time (secondary analysis).

Methods: Cross-sectional study, with a secondary longitudinal component, of 58 patients with biochemically controlled acromegaly. All had participated in studies assessing QoL years previously, after having undergone surgery ± radiotherapy.

Objective: Overweight/obesity is associated with relative growth hormone (GH) deficiency and increased fracture risk. We hypothesized that GH administration would improve bone endpoints in individuals with overweight/obesity.

Design: An 18-month, randomized, double-blind, placebo-controlled study of GH, followed by 6-month observation.

Objectives: To assess the impact of virtual education programming for patients with acromegaly.

Design: We conducted a mixed methods study to evaluate patient attitudes, examine if patient-centered educational forums change these attitudes, and determine the role of virtual education as a means to learn about patients' unmet needs, self-reported outcomes, and educational priorities.

Methods: The study included 653 total virtual program registrants.

Anorexia nervosa is complicated by low bone mineral density (BMD) and increased fracture risk associated with low bone formation and high bone resorption. The lumbar spine is most severely affected. Low bone formation is associated with relative insulin-like growth factor 1 (IGF-1) deficiency.

Objective: Acromegaly is associated with impaired quality of life (QoL). We investigated the effects of biochemical control of acromegaly by growth hormone receptor antagonism vs somatostatin analog therapy on QoL.

Design: Cross-sectional.

Objective: Low-dose testosterone has been shown to improve depression symptom severity, fatigue, and sexual function in small studies in women not formally diagnosed with major depressive disorder. The authors sought to determine whether adjunctive low-dose transdermal testosterone improves depression symptom severity, fatigue, and sexual function in women with antidepressant-resistant major depression. A functional MRI (fMRI) substudy examined effects on activity in the anterior cingulate cortex (ACC), a brain region important in mood regulation.

Objective: The neuroactive steroid metabolite of progesterone, allopregnanolone, is a positive allosteric modulator of γ-aminobutyric acid-A (GABAA) receptors and a putative treatment for mood disorders. This pilot study was performed to determine whether an oral allopregnanolone analog (ganaxolone) may be effective adjunctive therapy for persistent depression despite adequate antidepressant treatment in postmenopausal women.

Method: Ten postmenopausal women (mean ± SD age: 62.

The neuroactive steroid 3α-5α-tetrahydroprogesterone (allopregnanolone), a metabolite of progesterone, is a positive allosteric modulator of GABA receptors, and low levels have been implicated in the etiology of mood disorders. However, it is not known whether metabolism of progesterone to allopregnanolone varies across the menstrual cycle or is low after menopause. We hypothesized that the allopregnanolone/progesterone ratio would decrease from the follicular to luteal phase.

Context: Premenopausal women with anorexia nervosa (AN) and obesity (OB) have elevated fracture risk. More plate-like and axially aligned trabecular bone, assessed by individual trabeculae segmentation (ITS), is associated with higher estimated bone strength. Trabecular plate and rod structure has not been reported across the weight spectrum.

Context: Anorexia nervosa (AN) is a psychiatric illness with considerable morbidity and no approved medical therapies. We have shown that relative androgen deficiency in AN is associated with greater depression and anxiety symptom severity.

Objective: To determine whether low-dose testosterone therapy is an effective endocrine-targeted therapy for AN.

Asplenic patients are at increased risk for sepsis and fulminant infection. Sepsis in these patients is typically secondary to encapsulated bacteria, with Streptococcus pneumoniae being the most frequent pathogen. Rare complications of severe sepsis include purpura fulminans and bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome).

Accurate condom use assessment is critical in sexually transmitted infection-prevention research. Ordinal condom use frequency measures may be problematic due to subjective interpretation by respondents. To assess this potential bias, we examined the ordinal condom use labels (e.
