Biochemical parameters in metabolic bone disease of obese patients

Binda Pereira Raquel , Santos Ana Carolina , Ferreira Joana , Mascarenhas Mario Rui , De Quinhones Levy Pilar , Barbosa Paula , Bicho Manuel

Introduction: Obesity is a pathological condition characterized by a low-grade systemic inflammatory state that predisposes to the onset of some diseases, such as hypertension, diabetes, and hyperlipidemia. Also, obesity can impact bone metabolism, but its effects are controversial.Aims: This observational study aimed to evaluate and correlate the bone mass with the lipidic profile, adipocytokines, glucose metabolism, hepatic function and purine metaboli...

Osteoporosis after menopause: interaction between genes related to iron metabolism and estradiol

Aguiar Laura , Ferreira Joana , Pereira Raquel Binda , Barbosa Ana Paula , Rui Mascarenhas Mario , Faustino Paula , Inacio Angela , Bicho Manuel

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...

Primary bilateral macronodular adrenal hyperplasia: Is unilateral adrenalectomy enough?

Lopes-Pinto Mariana , Fialho Mafalda Pinho , Ricca Lacerda Nobre M Caetano Ema Paula , Rocha Jose , Barbosa Ana Paula

Introduction: Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) represents <2% of causes of Cushing’s Syndrome (CS). Clinical course is insidious, with adrenal bilateral macronodules and gradual cortisol excess, only rarely presenting with overt CS. The pathophysiology remains unclear, however, hyperactivation of the cAMP/PKA pathway, in 77-87% of cases through aberrantly expressed G-protein coupled receptors (GPCRs), has been described. Despite being a benig...

Neuroendocrine neoplasia and obesity

Nunes Adriana , Medeiros Gertrudes M , Velloso Renata N , Gurjao Edmar C , Nunes Adriana B , Barbosa Paulo E S

Neuroendocrine neoplasia (NENs) are rare tumours that show features of neuroendocrine differentiation. Generally, NENs can be subdivides into high-grade neuroendocrine carcinomas (NECs) and low-to-intermediate grade neuroendocrine tumours (NETs). The most common Endodermal NETs’ localisations are the lungs, ileum, appendix, and rectum. Neuroectodermal NETs include medullary thyroid cancer (MTC), pheochromocytoma (PHEO), and paraganglioma (PGL). Nets are estimated to occur...

Sex hormone-binding globulin protects against non-alcoholic fatty liver disease

Lopez Cristina Saez , Barbosa-Desongles Anna , Hernandez Cristina , Dyer Roger A , Innis Sheila M , Rafael Simo , Selva David M

Low plasma sex hormone-binding globulin (SHBG) levels are present in patients suffering chronic metabolic diseases, including non-alcoholic fatty liver disease (NAFLD). However, whether altered SHBG production plays a role in development and progression of this disease is unclear. To investigate SHBG involvement in NAFLD, we studied the effects of overexpressing SHBG in two mouse models, a genetically-induced model, by developing a double transgenic mouse by crossing the human...

May the polymorphism of low molecular weight protein tyrosine phosphatase modulate metabolic and bone remodelling parameters associated with osteoporosis?

Freitas Joana , Monteiro Cristina , Barbosa Ana Paula , Batista Fatima , Laires Maria Jose , Bicho Manuel , Mascarenhas Mario Rui

Aims: To study the association of protein tyrosine phosphatase (LMW–PTP/ACP1) polymorphism with bone mineral density and metabolic parameters of bone remodelling.Methods: BMD (g/cm2) was measured by DEXA in 760 subjects: 448 normal BMD (359F/89M; 49.7±12.9 years; 30.2±5.4 kg/m2) and 312 osteoporosis (265F/47M; 63.9±10.4 years; 27.16±4.4 kg/m2). Metabolic bone remodelling parameters were analyzed: ...

Placental IGF1R–PI3K/Akt pathway and its relationship to idiopathic birth weight alterations

Lazo-de-la-Vega-Monroy Maria-Luisa , Gonzalez-Dominguez Martha I , Daza-Benitez Leonel , Barbosa-Sabanero Gloria

Introduction: Alterations in foetal growth lead to neonatal health risks and favour metabolic diseases during adult life. Therefore, the study of birth weight determination and its modifications is crucial for metabolic diseases prevention. Placental growth is a key factor in foetal growth. It has been suggested that insulin and the IGF system play an important role in foetal growth and placental development and function. Although, insulin and IGFs in the umbilical cord blood ...

Semen quality improvement after weight loss by very low-calorie ketogenic dietary: A report of two cases

Renck Alessandra , Afonso Teixeira Thiago , Risso Pariz Juliana , Barbosa Trarbach Ericka , Hallak Jorge , Maria Frade Costa Elaine

Considered as the biggest public health problem, the pandemic growth of obesity is associated to decline of male fertility potential over the last 50 years. Thus far, the effect of weight loss on semen parameters is still controversial and poorly understood. In this study we report the effect of significant weight loss on semen parameters of two obese men with metabolic syndrome. The patients followed to a very low-calorie ketogenic diet (VLCKD) according to a commercial weigh...

Cito-histologycal correlations in nodular thyroid pathology

Couto Joana , Lobo Claudia , Barbosa Ana Paula , Martins Raquel , Santos Ana Paula , Monteiro Paula , Amaro Teresina , Torres Isabel

Introduction: Fine needle biopsy (FNB) is a very important diagnostic tool in the assessment of thyroid nodules and plays a prominent role in therapeutic approach. It has a sensitivity around 83 to 85% and a specificity around 80 to 92%.Aims: To correlate cytological (FNB) and final histopathological data in patients with nodular thyroid pathology.Methods: A retrospective study of patients who underwent surgical procedure from Janu...

Somatostatin analogues as an alternative treatment for type 1 gastric endocrine tumour: case report

Santos Ana P , Martins Raquel G , Couto Joana , Barbosa Ana P , Abreu Nuno , Leca Luis , Torres Isabel

Introduction: Gastric endocrine tumors (GET) are rare. Type 1 tumors are non-functioning, almost exclusively benign lesions, usually presenting as multiple polyps, usually <1 cm in diameter, which arise from gastric enterochromaffin-like cells in response to chronically elevated gastrin, secondary to (auto-immune) atrophic fundic gastritis. These tumors were traditionally treated with total gastrectomy, like adenocarcinomas. Currently, surveillance or endoscopic treatment ...
