Changes in body weight in various population groups in Poland during the COVID-19 pandemic - a comparison of two cross-sectional studies.

Introduction And Objective: The disruption of daily activities caused by the COVID-19 pandemic had health consequences, especially during peak lockdown periods. The aim of the study is to assess the impact of the first year of the COVID-19 pandemic on the process of weight change among Polish adults.

Material And Methods: Two representative studies involving Polish adults aged 18-65 years were conducted, the first in June 2020 (N = 2527, from the perspective of the last 2-3 months), and the second a year later, in June 2021 (N = 2087, covering the last 12 months).

Body weight and assessment of sexual life - a cross-sectional study.

Introduction And Objective: Body weight can be one of the health effects affecting people's well-being in its many aspects. The aim of the study was to assess the relationship between body weight and sexual life.

Material And Methods: In June 2020 a survey was conducted online on a nationwide representative group of 3,000 Poles.

Prevalence of estrogen receptor alpha PvuII and XbaI polymorphism in population of Polish postmenopausal women.

Numerous data indicate that polymorphism of estrogen receptor alpha (ERalpha) may predict lipid levels, lipid response to hormone replacement therapy (HRT), myocardial infarction risk, bone fracture risk, bone mineral density (BMD) and changes in BMD over time. In this study we aimed to evaluate distribution of ERalpha PvuII and XbaI genotypes in population of Polish postmenopausal women qualified to different protocols of HRT. Subject of the study were 64 consecutive postmenopausal women aged from 45 to 65 years (mean 56.

Relationship between estrogen receptor-alpha polymorphism and serum levels of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, C-reactive protein and homocysteine in postmenopausal women.

Background And Aim: Genetic variation in the estrogen receptor-gene (ERalpha) may influence the risk of cardiovascular diseases in postmenopausal women. This effect, at least in part, may be dependent on the decrease in expression of injury and inflammatory markers in the vascular wall. The aim of the present study was to evaluate the relationship between ERalpha PvuII and XbaI polymorphisms and serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), C-reactive protein (CRP) and homocysteine in postmenopausal women.

Effect of estradiol and raloxifene on MUC1 expression and adhesive properties of Ishikawa cells.

The MUC1 is a transmembrane protein with a large mucin-like extracellular domain protruding high above the cell surface. Steroid regulation of MUC1 gene expression is essential, since overexpression of MUC1 may influence the metastatic potential of cancer cells. Our earlier results demonstrated that tamoxifen, alone and combined with estradiol, inhibits MUC1 biosynthesis in endometrial adenocarcinoma cells, in contrast to estradiol.

Estrogen receptor alpha and beta expression in uterine leiomyomas from premenopausal women.

Objective: To measure messenger RNA levels of estrogen receptor (ER) alpha and beta in uterine leiomyomas, normal myometrium, and endometrium.

Design: Prospective study.

Setting: University hospital.

Differential effects of raloxifene and tamoxifen on the expression of estrogen receptors and antigen Ki-67 in human endometrial adenocarcinoma cell line.

Tamoxifen and raloxifene are widely used in clinical practice. It has been found that tamoxifen treatment increases the risk of development of endometrial cancer. The effects of tamoxifen and raloxifene on endometrium might be caused by different estrogen receptor expression.

Differential effects of estradiol, raloxifene and tamoxifen on estrogen receptor expression in cultured human skin fibroblasts.

The balance between ER-alpha and ER-beta in fibroblasts may be crucial in the physiological response to ligands. Up- or down-regulation of the ERs in response to different compounds could mediate the reversal of certain age-related changes in skin and connective tissue. The time-dependent effects of 17-beta estradiol, raloxifene and tamoxifen on ER-alpha and ER-beta mRNA expression in the skin fibroblast cultures were performed.

Differential effects of estradiol and raloxifene on collagen biosynthesis in cultured human skin fibroblasts.

The dose-dependent effect of a 24 h treatment with estradiol (E(2)) (1, 2, 5, 10 nM) and raloxifene (Rx) (1, 5, 10, 20 microM) on ER alpha and ER beta mRNA expression, collagen bio-synthesis, prolidase activity, MMP-2, MMP-9, insulin-like growth factor I receptor expression (IGF-1R) and beta1-integrin expressions in cultured fibroblasts obtained from postmenopausal women were examined. Both ligands increased mRNA expression of ER compared to control. Rx at 5 and 10 microM concentrations had greater stimulative effect on collagen biosynthesis, prolidase activity and IGF-1R expression compared to E(2) at 2 and 5 nM concentration.

A comparative study of cefaclor vs amoxicillin/clavulanate in pediatric pharyngotonsillitis.

Background: Pharyngotonsillitis (PT) caused by group A beta hemolytic streptococci (GABHS) is one of the most common infections of childhood. Two antibiotic suspensions, cefaclor (CEF) and amoxicillin/clavulanate (AMC), are commonly used in Poland for the treatment of PT caused by GABHS in children.

Material/methods: This multi-center, randomized, single-blinded study was undertaken in order to compare the efficacy and safety of CEF (20 mg/kg/d) and AMC (25 mg/kg/d) in 10 days treatment of GABHS-related PT.

Human cultured skin fibroblasts express estrogen receptor alpha and beta.

Human skin fibroblasts may be the target cells for estrogens. The aim of present study was to confirm the presence of both isoforms of estrogen receptors (ER) in these cells. Experiments were carried out in primary cultures of human skin fibroblasts.

Comparative study of cefaclor AF vs. cefuroxime axetil in acute exacerbations of chronic bronchitis.

Background: Acute exacerbations of chronic bronchitis (AECB) are the most common complication of chronic bronchitis. The majority of AECB are caused by infection. The choice of appropriate antibacterial therapy for AECB is becoming more difficult and is usually empirically.
