Age- and sex-adjusted CT-based reference values for temporal muscle thickness, cross-sectional area and radiodensity.

Muscle mass has been traditionally assessed by measuring paraspinal muscle areas at the level of the third lumbar vertebra on computed tomography (CT). Neurological or neurosurgical patients seldom undergo CT scans of the lumbar region. Instead, temporal muscle thickness (TMT), cross-sectional area (TMA) and radiodensity measured from head CT scans are readily available measures of muscle mass and quality in these patient cohorts.

Ferritin Levels in Women with PCOS.

Objective: To study ferritin levels, and potential factors influencing them, in women with polycystic ovary syndrome (PCOS), and to investigate potential associations between ferritin levels and other parameters in these women.

Design: Longitudinal general population -based cohort study, including data from both questionnaires and clinical measurements.

Subjects: The study was conducted with data from the participants of the Women's Health Study, including a total of 1918 Finnish women, around 35 years of age.

Association of hemoglobin levels with metabolic traits in women with PCOS.

Introduction: Within normal variation, higher hemoglobin (Hb) levels are associated with poorer metabolic profile in population cohorts, underlying the link between oxygen delivery and cell metabolism. Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women and is commonly accompanied by metabolic derangements. In this study we sought to investigate Hb levels, and their metabolic associations, in women with PCOS.
