Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder affecting women of reproductive age. The main features of PCOS are hyperandrogenism and reproductive and metabolic dysfunctions. We have previously shown that muscle contractions induced by either electrical stimulations or exercise act through partially similar signaling pathways in the muscle to induce glucose uptake in the acute response. Long-term electrical stimulations decrease circulating testostero...

Introduction: Longitudinal changes in pancreatic neuroendocrine tumor (panNET) cell proliferation correlate with fast disease progression and poor prognosis. The optimal treatment strategy for secondary panNET grade (G)3, that has progressed from a previous low- or intermediate-grade to high-grade panNET G3 is currently unknown. Methods: This was a single center retrospective cohort study, aimed to characterize treatment patterns and outcomes among patie...

Background: The study aimed to evaluate quality-of-life (QoL) aspects and impact of vitamin D deficiency in primary hyperparathyroidism (pHPT).Method: 150 consecutive patients (119 women) with pHPT (mean age 60±11 years; BMI 27±5 kg/m2; ionized calcium 1.44±0.08 mmol/l; PTH 130±69 ng/l) were included. Six weeks postoperatively, the pHPT patients were reexamined and randomized (double-blind) to daily substitution with calciu...

Background: The study aimed to evaluate quality-of-life (QoL) aspects and impact of vitamin D deficiency in primary hyperparathyroidism (pHPT).Method: One hundred and fifty consecutive patients (119 women) with pHPT (mean age 60±11 years; BMI 27±5 kg/m2; ionized calcium 1.44±0.08 mmol/l; PTH 130±69 ng/l) were included. Six weeks postoperatively, the pHPT patients were reexamined and randomized (double-blind) to daily substi...

Polycystic Ovary Syndrome (PCOS) is an endocrine disorder affecting 10-15% of women worldwide, characterized by high androgen levels, anovulation and/or polycystic ovarian morphology. Chronic low-grade inflammation is associated with the disorder as well as many of its comorbidities, such as obesity and type-2 diabetes. To determine the role of the immune system in the pathophysiology of PCOS, we characterized the immune profile of the dihydrotestosterone (DHT)-induced PCOS-li...

Introduction: Polycystic ovary syndrome (PCOS) is the leading cause of female infertility and is associated with high degree of comorbidities including type 2 diabetes and endometrial cancer. Hyperandrogenemia is a hallmark of PCOS and contributes to endometrial-related dysfunctions, including implantation failure and miscarriage. Whether cellular heterogeneity contributes to the functioning of the endometrium is not previously studied. Therefore, the aim is to reveal cell-typ...

White adipose tissue (WAT) is a dynamic and heterogeneous organ composed of different cell types involved in a wide array of biological processes. We know that women with polycystic ovary syndrome (PCOS) suffer from insulin resistance and type 2 diabetes which is associated with pathological white adipose tissue (WAT) function and expansion characterized by hypertrophic adipocytes, altered production and release of lipids and adipokines, and chronic low-grade tissue inflammati...

Background: Hashimoto´s thyroiditis (HT) and Graves´ disease (GD) are known co-aggregate in families, but the magnitude and nature of a shared etiology is unknown. The aim of this study was to estimate the shared genetic influence on these diseases. In addition, we sought to examine if the heritability of HT and GD differs between men and women.Methods: We used national health registries to identify cases of HT and GD in a cohort of 110 814 Swe...

Objective. Recent studies suggest that in utero programming of the hypothalamo-pituitary-adrenal axis is important in explaining the link between small size at birth and adult cardiovascular disease. We therefore examined the relationship between adult cortisol concentration and measurements at birth.Subjects. 420 men and women (mean age 69.5, range 65.0-75.8 yrs) born and living in Helsinki, Finland, with detailed birth records.<p class="ab...

Objective: Age-associated double negative (DN) B memory cells lacking surface expression of CD27 and immunoglobulin D (IgD) are associated with proinflammatory characteristics and higher disease activity in autoimmune diseases. We first characterized B cells phenotypes in women with and without polycystic ovary syndrome (PCOS). We then took an in vivo approach, transferring purified IgG extracted from serum of hyperandrogenic women with PCOS to mice to establish wheth...
