Irisin is an adipomyokine produced during physical activity and implicated in the browning of adipose tissue. Existing evidence suggests an inverse relationship between irisin plasma levels and adverse metabolic outcomes; however, the exact impact of diet on irisin levels remains unclear. We aimed to assess the effects of two dietary patterns, Christian Orthodox fasting (OF) and 16:8 time-restricted eating (TRE), on irisin concentrations among overweight, metabolically healthy...

Background: Overshoot of weight regain following the treatment of hyperthyroidism is well described. Notwithstanding, there is a large interindividual variability in the observed weight changes. This study aims to identify parameters predicting excessive weight gain in hyperthyroidism patients.Methods: In a retrospective study of a prospectively completed database, we recruited consecutive patients with overt hyperthyroi...

Background: Data on the effects of different dietary patterns on free 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) concentrations are scarce. Our objective was to prospectively assess changes over time in these parameters and possible correlations with diet composition among overweight adults who followed a pescatarian Orthodox intermittent fasting (OF) regimen and controls who followed a low-fat 12:12 diet for 7 weeks.Methods: Tota...

Introduction: Hashimoto’s thyroiditis is known to induce nodularity in the thyroid and in some cases to coexist with papillary thyroid carcinoma. However, the effect of the development of Hashimoto’s thyroiditis on the course of nodular goiter is not known.Aim: The aim was to describe the effect of the development of Hashimoto’s thyroiditis in the course of nodular goiter.Methods: A cohort of 12 patients, female, age...

Introduction: Patients with systemic sclerosis may develop cancer. The development of malignant hematological diseases has also been described in patients with systemic sclerosis. These patients may also be prone to the development of lymphoma, in most cases a B-cell lymphoma.Aim: The aim was to describe the case of a patient with systemic sclerosis who had a non-Hodgkin’s lymphoma and developed primary hypothyroidism.Case rep...

Introduction: Diseases of the gastrointestinal tract may have on effect on bone quality manifesting either as osteomalacia or as osteoporosis. Gastritis may have an effect on bone as it requires long term treatment with proton pump inhibitors. Gastrointestinal neoplasms may be accompanied by nutrient malabsorption. These diseases may also be related with vitamin D deficiency.Aim: The aim was to describe two cases of gastrointestinal diseases, namely chro...

Introduction: 21-hydroxylase deficiency (21-OHD) is a common inherited disorder accounting for 90–95% of congenital adrenal hyperplasia (CAH) cases. Some cases may be diagnosed in adulthood after the incidental discovery of adrenal masses on computerized tomography (CT).Case report: A 59-year-old male was investigated for incidentally discovered bilateral adrenal masses in an abdomen CT scan, measuring 5 cm on the right and 8 cm on the left adrenal....

Objective: Quality of life is currently considered a major factor in the assessment of disease outcome. The aim was to assess quality of life in acromegaly and the effect of somatostatin analogues on it.Design: This study included 101 patients with acromegaly, mean age 59.51±1.35 years (mean ± S.E.M.), with a disease duration of 12.88±0.96 years. All subjects completed the Acromegaly Quality of Life Questionnaire (AcroQoL) w...

Background: Lack of expression of MGMT (O-6-methylguanine-DNA methyltransferase) is associated with a better tumour response to temozolomide. There are no systematic studies of MGMT expression in pituitary tumour series.Aim: We introduced MGMT immunohistochemistry for all pituitary adenoma specimens in 2011. In this study we investigated the immunohistochemical expression of MGMT in a large series of pituitary adenomas, in order to determine (1) the over...

Background: 25 hydroxy vitamin D (25(OH)D) vitamin levels are positively associated with bone mineral density and season, time of day and sun exposure duration influence its synthesis. Variations in daylight throughout the year and zenith angle, depending on the latitude of residence, influence u.v. solar radiation which is closely related to serum 25(OH)D levels. The aim of this study was to investigate the degree of seasonal variation of 25(OH)D serum levels in a population-...
