Objectives: To evaluate the relationship between free T3 (FT3) levels with symptoms suggestive of thyroid dysfunction, and quality of life (QoL) outcomes, in patients with compensated primary hypothyroidism (PH).Methods: Cross-sectional study encompassing Portuguese levothyroxine(LT4)-treated patients for PH who presented Thyroid-stimulating hormone (TSH) and free T4 (FT4) within the normal range. Pregnant women, patients with central hypothyroidism and/...

Introduction: The anatomical and physiological changes induced by bariatric surgery (BS) can significantly impact the absorption and pharmacokinetics of orally administered medication. In particular, levothyroxine (LT4) dosage, given its dependence on patient’s weight and gastric pH for optimal absorption, is expected to change following BS. However, the literature is not unanimous and there is a void of longer-term studies. We aimed to compare LT4 dosage 4 years followin...

Introduction: Immunotherapy has demonstrated a key role in the current individualized treatment of multiple neoplasms, with adverse events related to the endocrine. Thyroid dysfunction is the most frequent reported endocrine event during treatment with pembrolizumab, being autoimmune diabetes an extremely rare adverse effect.Case Report: We present a case of a 72-year-old man with a progressing urothelial bladder carcinoma (stage IIIB), under treatment w...

Due to decreasing ovarian reserve from young age, counselling is vital as chances to conceive spontaneously decrease rapidly and early consideration of fertility options essential. Maternal/fetal-risks are high and patients/specialists face important considerations.Aim: Service-evaluation of adequacy/appropriateness/sufficiency of information about fertility provided to TS patients.Methods: TS women attending two TS-dedicated-centr...

Mutations of the calcium-sensing receptor (CaSR), G-protein alpha-11 subunit (Gα11), and adaptor protein-2 sigma subunit (AP2σ) resulting in a loss-of-function, cause familial hypocalciuric hypercalcemia types 1-3 (FHH1-3), respectively. We investigated a family with FHH (four affected and two unaffected members) for CaSR, Gα11 and AP2σ mutations, and identified a heterozygous Gα11 missense mutation, Phe220Ser, which is predicted to disrupt a cluster o...

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive age women and is characterized by reproductive, metabolic and psychological features exacerbated by weight gain. Weight management in PCOS is challenged by propensity to weight gain and lack of sustainable dietary interventions. Body weight is regulated by calorie intake and the rate of energy expenditure. Metabolically active brown adipose tissue (BAT), contributing to energy dissipation, has b...

Introduction: Although thyroid nodules (TN) are less common in children than in adults, the risk of malignancy is much higher in pediatric age and therefore representing greater concern in this age group.Objective: Evaluate a cohort of pediatric patients with TN and search differences between subjects with malignant and benign TN regarding sex, age, compressive symptoms, cervical ultrasound characteristics, family history of differentiated thyroid cancer...

Introduction: Incidence of Digestive NETs (DNETs) has increased in the last 40 years. Visceral obesity, metabolic syndrome (MetS) and insulin resistance (IR) have been associated with several types of cancer.Aim: To evaluate possible associations of obesity, hyperinsulinemia and IR with well-differentiated (WD) DNETs through a case control study.Materials and methods: Ninety-six patients with gastrointestinal (75.0%) and pNET (22.9...

Background: Polycystic ovary syndrome (PCOS) is associated with features linked to metabolic syndrome including visceral adiposity, dyslipidemia and impaired glucose homeostasis. Adipose tissue produces adipocytokines which contribute to regulation of insulin sensitivity and reproduction. Omentin-1 is an adipokine with anti-inflammatory and insulin sensitizing roles produced by adipocytes. The exact role of mentin-1 in PCOS remains unclear as studies have reported reduced or u...

The currently best known example of a commercialized theranostics is the combination of HercepTest and Herceptin wherein the former is used for HER2 expression assessment and selection of patients that might benefit from the treatment with the latter. However, HercepTest requires biopsy which is an invasive procedure, not sufficiently accurate, and very difficult to perform on several lesions and repeatedly in order to monitor the treatment response. While positron emission to...
