Rationale: The Global Leadership Initiative on Malnutrition (GLIM) criteria was recently proposed as the world’s first diagnostic criteria for malnutrition in adults in hospital settings. The GLIM approach is based on the assessment of three phenotypic and two etiologic criteria, with diagnosis confirmed by any combination of one phenotypic and one etiologic criterion fulfilled. The purpose of this study was to evaluate the prevalence phenotypic criteria of GLIM in hospit...

Objective Vitamin D (VD) plays a role in immune response. Recent data shows that low levels of VD could worsen COVID-19 outcomes. This study aimed to establish an association between VD levels among COVID-19 patients with clinical outcomes and inflammatory markers.Methods Prospective multicentric cohort study. Consecutively recruitment. Patients were grouped according admission status and level of VD [sufficient >30 ng/ml (VDS), insufficient 20–...

Neuroendocrine tumors (NETs) and carcinomas (NECs) are a heterogeneous group of malignances whose incidence is increasing worldwide. First-line approach is represented by surgery, whereas an effective pharmacological treatment for disseminated and relapsing disease is still needed. Somatostatin (SS) receptors (SSTs) constitute the main suitable pharmacological targets for NETs therapy with SS analogs (SSAs). Nevertheless, a large proportion of NETs and most NECs, are unrespons...

Introduction: 177Lu-Oxodotreotide(PRRT-Lu) has the approval by EMA and FDA since 2017 for the treatment of patients with gastro-entero-pancreatic neuroendocrine tumors(GEP-NET). However, in daily clinical practice it has also been used in other NET tumors such as paragangliomas, lung NET, medullary thyroid cancer, and others. The aim of this study is to describe the characteristics and follow-up of patients treated with PRRT-Lu in a third level hospital in Spain fro...

Background: The initiation of puberty is heralded by increasing gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus. During embryonic life the GnRH neuroendocrine network develops thanks to a coordinated migration of neurons from the nasal placode to the forebrain. Our group has previously demonstrated that dysregulation in GnRH neuronal migration leads to delayed pubertal onset. Late puberty affects up to 2% of the population and is associated with adverse h...

Introduction: Treatment of hypothyroidism with levothyroxine is effective and simple; however, international guidelines advise starting with low doses in case of severe hypothyroidism, cardiac illness and aged population. Interestingly, and in contradiction to this dogma, high doses of levothyroxine have been given to patients with myxedema coma without untoward effects. The difference between myxedema coma, which deserves an intensive treatment, and longstanding severe hypoth...

Introduction: A new subtype of diabetes, ketosis-prone diabetes (KPD) has been described in the last years among African, Asian and Hispanic population with characteristics similar to type 1 diabetes (DM1) such as cardinal symptoms, tendency to ketosis and decreased pancreatic reserve at onset, but with negative autoimmunity. The aim of this study was to compare this type of patients with those with type 1 diabetes at onset and their evolution.Material a...

Introduction: Papillary thyroid cancer (PTC) has an excellent prognosis in most cases with a 10-year survival rate of more than 95% but decreases drastically in cases of PTC iodine-refractory, in recurrent and/or metastatic disease. Tyrosine kinase inhibitors, such as lenvatinib or sorafenib, have been approved in such cases and in some cases are able to stabilize the disease and prolong survival. However, serious side effects have been reported such as fistula formation, blee...

Introduction: Myxedema coma is a rare life-threatening clinical condition in patients with longstanding severe untreated hypothyroidism, in whom adaptive mechanisms fail to maintain homeostasis. Most patients, however, are not comatose, and, although strict criteria have been proposed, it is often difficult to differentiate it from very severe hypothyroidism, lacking only a precipitating event.Material and methods: We present the clinical picture of 70 c...

Introduction: Abnormalities of lipid metabolism and arterial hypertension occur with increased frequency in hypothyroidism and are associated with a higher risk of premature atherosclerotic vascular disease. Therefore, a vigorous lipid lowering treatment seems mandatory, including quickly restoration of thyroid function, to reduce vascular risk. We evaluate benefits on lipid profile after intravenous thyroxine treatment in severe hypothyroid patients at three and thirty days.<...
