Introduction: Osteoporosis is a common metabolic bone disease characterized by reduced bone mass and increased risk of fragility fractures. The pathogenesis of this disease is complex and influenced by multiple risk factors, where genetic factors play an important role. Menopause predisposes women to osteoporosis due to declining estrogen levels. Osteoporosis and iron metabolism have an important relationship. Iron overload suppresses osteoblast formation and stimulate osteocl...

Objectives: Hürthle cell (oncocytic) lesions can be metaplastic or neoplastic events. The neoplastic entities -formerly, oncocytic variant of follicular tumours; Hürthle cell neoplasm (HCN) - include HC adenomas and HC carcinomas and have been recognized as a separate class of tumours by the WHO. The remaining of the thyroid tumours demonstrating “mitochondrion-rich cells” and oncocytic morphology are referred under the umbrella term of “oncocytic vari...

Infertility affects about 15% of couples, and, among these, 50% are related to the male factor. Male infertility can be caused by intrinsic factors, and these may either directly or indirectly affect gamete and testicular development as a consequence of endocrinopathies. In that sense, research regarding the involvement of endocrine hormones, particularly of nutritional status-linked hormones, in the male reproductive system has increased over the years. In fact, the rise on t...

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...

Introduction: The development of new pharmacological classes for type 2 diabetes (T2D) treatment with extra-glycaemic benefits has led to the update of the treatment algorithm, presenting new effective alternatives to patients’ insulinization. The present study aims to evaluate the evolution of prescription and its impact in metabolic control of patients enrolled on an educational diabetes program of a tertiary hospital.Objectives: To evaluate trend...

Primary aldosteronism (PA) is the cause of 5–10% of hypertension, surgically curable in patients with unilateral aldosterone-producing adenomas (APAs). However <1% of patients are currently diagnosed and cured. Newer and simpler modalities of diagnosis and treatment are required. The aim of FABULAS (a feasibility study of endoscopic ultrasound-guided ablation as a non-surgical, adrenal sparing treatment for aldosterone-producing adenomas) is to determine in 30 patient...

Introduction: Eating habits may contribute to longevity. Consumption of red meat, source of saturated fatty acids and cholesterol may be associated with increased risks of diabetes, cardiovascular disease (CVD), and mortality risk.Methods: We studied 521 subjects, both genders, 253 centenarians (CENT) (100.26±1.98 age) and 268 controls (67.51±3.25 age), both low (LCR) and high cardiovascular risk (HCR), calculated based on QRISK®2-2016. An...

Introduction: Anti-Müllerian Hormone (AMH) is a useful marker of ovarian reserve (OR), since it remains stable inter/intra-cycles and presents a good correlation with ultrasonographic antral follicular count. Obesity/overweight are increasing and may affect the reproductive health. However, previous studies regarding the effect of body mass index (BMI) on AMH levels are discordant. Our main goal was to evaluate the influence of BMI in AMH levels in women with infertility....

Introduction: Differentiated thyroid cancer (DTC) is one of the most frequent forms of malignancy. Because of its favourable outcome and low mortality rates, identifying prognostic factors has been a challenge. Several risk stratification systems have been developed. Most of them include demographic and tumour specific features, as well as extrathyroidal extension. Our objective was to compare clinical characteristics between DTC patients with and without remission.<p clas...

Introduction: Bariatric surgery (BS) candidates display several nutritional deficiencies that can aggravate after surgery. Metabolic syndrome (MS) is a cluster of cardiovascular risk factors with several disturbed metabolic pathways. Therefore, individuals with MS submitted to BS are probably more prone to nutritional deficiencies.Objective: To evaluate the prevalence of nutritional deficiencies and eventual differences between BS candidates with and wit...
