Defending body weight is a fundamental homeostatic process. Indeed, countless studies have demonstrated weight-maintaining hyperphagia in response to either increased energy expenditure or a reduction in the caloric density of available food. The principal effector of this adaptive food intake is thought to be the adipose tissue-derived hormone, leptin. According to the classical ’adipostat’ model, the hypoleptinemia resulting from weight loss drives food intake to r...

Menopause management guidelines advocate a personalised, evidence-based approach to menopause-care. This study explored the current landscape of menopause-care, from both patients’ and healthcare-providers’ perspectives, to better understand barriers to menopause-care across the UK.Methods: A 25-question online patient-survey and a 23-question GP-survey was designed with individuals with lived-experience of menopause to underst...

Introduction: Kallmann syndrome (KS) is a rare genetic disorder typically due to defective migration of olfactory-axons and GnRH-neurons. KS results in congenital hypogonadotrophic hypogonadism (CHH) typically associated with absent (anosmia) or reduced (microsmia) sense of smell. Unilateral hypoplastic/absent olfactory bulbs on MRI are reported, although disturbance in smell is usually bilateral. Here, we present an unusual case of KS with unilateral anosmia....

Introduction: Kallmann syndrome (KS) is a rare condition characterised by congenital hypogonadotropic hypogonadism (CHH), usually due to defective migration of olfactory axons and GnRH-neurons. KS is typically associated with absent (anosmia) or reduced (microsmia) sense of smell. Unilaterally hypoplastic or absent olfactory bulbs on MRI are reported, although disturbance in smell is usually bilateral. Kisspeptin is a potent stimulator of hypothalamic GnRH-neurons, and endocri...

Loss of gonadotropin-releasing hormone (GnRH) and cognitive deficits have recently been demonstrated by our group in conditions including Down syndrome and Alzhiemer’s disease. In some patients with COVID-19, olfactory and cognitive alterations persist, and persistent hypotestosteronemia in SARS-CoV-2-infected men could be a consequence of deficient GnRH. To understand whether neuroinvasion of GnRH system by SARS-CoV-2 could explain some post-COVID symptoms and thus resul...
