Overweight postmenopausal women with different plasma estradiol concentrations present with a similar pattern of energy expenditure and substrate oxidation rate before and after a fatty meal challenge.

Menopause-related withdrawal of ovarian estrogens is associated with reduced energy metabolism and overall impairment of substrate oxidation. Estradiol's withdrawal after menopause is associated with a reduction in energy metabolism and impaired substrate oxidation, which contributes to weight gain and visceral fat accumulation. Here we aimed to investigate the association between plasma estradiol concentrations and energy expenditure (EE)/substrate oxidation in a group of overweight postmenopausal women before and after a fatty meal challenge.

Effects of Short-Term Calcium Supplementation in Children and Adolescents with Phenylketonuria.

Reduction of bone mineral density and the risk of osteopenia have been reported to occur in phenylketonuria (PKU) patients. This study aimed to evaluate the short-term effects of calcium supplementation in phenylketonuric children and adolescents. The study included 18 patients with PKU aged 5-18 yr (61% male) under clinical and nutritional treatment.

Quantitative ultrasound at the hand phalanges in patients with bisphosphonate-related osteonecrosis of the jaws.

Patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) who received intravenous or oral bisphosphonates (BP) were selected for determination of their bone microarchitecture as a risk predictor of BRONJ development. The diagnosis of BRONJ was made based on clinical and radiographic findings. The control group consisted of healthy patients.

Use of a Gonadotropin-releasing Hormone Analog to Treat Idiopathic Central Precocious Puberty Is Not Associated with Changes in Bone Structure in Postmenarchal Adolescents.

Study Objectives: To evaluate bone quantity and quality in postmenarchal adolescents treated for idiopathic central precocious puberty (CPP) in childhood with a gonadotropin-releasing hormone analog (GnRHa) and to determine the serum concentrations of bone remodeling markers.

Design And Participants: This cross-sectional study included 53 postmenarchal adolescent girls who were divided into 2 groups: 27 adolescents who were treated with GnRHa in childhood for idiopathic CPP (the CPP group) and 26 women who presented with physiological development of secondary sex traits (the control group).

Interventions: None.
