Loss of physiological nocturnal blood pressure (BP) decline is an independent predictor of cardiovascular risk and mortality. The aim of the study was to investigate the influence of body composition and fat distribution on 24-hour BP pattern and nocturnal dipping of mean arterial pressure (MAP) in patients with obesity. The study comprised 436 patients, 18 to 65 years old (306 women), with BMI ≥30 kg/m2.

Influence of preoperative weight loss on gastric wall thickness-analysis of laparoscopic sleeve gastrectomy histological material.

Purpose: The variables possibly enabling the prediction of gastric wall thickness during laparoscopic sleeve gastrectomy remain undetermined. The aim of the study was to identify preoperative factors affecting gastric wall thickness in patients undergoing laparoscopic sleeve gastrectomy.

Methods: The measurements of the double-wall thickness of gastric specimen excised during sleeve gastrectomy were taken at three locations after 15 s of compression with an applied pressure of 8 g/mm.

Characteristics of osteoporotic vertebral fractures in association with symptomatic status in postmenopausal women - a retrospective study of a single centre in Poland.

Introduction And Objective: Vertebral compression fractures (VCFs), which are a complication of osteoporosis, often cause diagnostic and therapeutic difficulties. The aim of this study was to find association between the characteristics of VCFs and the symptomatic status of patients.

Material And Methods: The study involved a total of 437 women with diagnosed postmenopausal osteoporosis (193 with at least one compression fracture and 244 without VCFs).

Current Applications and Selected Technical Details of Dual-Energy X-Ray Absorptiometry.

The application of dual-energy X-ray absorptiometry (DXA) examinations in the assessment of bone mineral density (BMD) in the lumbar spine, hip, and forearm is the basic diagnostic method for recognition of osteoporosis. The constant development of DXA technique is due to the aging of societies and the increasing importance of osteoporosis as a public health problem. In order to assess the degree of bone demineralization in patients with hyperparathyroidism, forearm DXA examination is recommended.

A cross-sectional comparison of selected anthropometric, laboratory, and densitometric parameters in postmenopausal osteoporotic women with and without vertebral compression fractures.

Introduction: Osteoporosis leads to an increased risk of vertebral compression fractures (VCFs). Most of them are spontaneous, which makes early diagnosis difficult. The aim of the study was to find parameters that distinguish osteoporotic women with and without vertebral compression fractures.

Comparison of the Characteristics of Back Pain in Women with Postmenopausal Osteoporosis with and without Vertebral Compression Fracture: A Retrospective Study at a Single Osteoporosis Center in Poland.

BACKGROUND The incidence of unspecific back pain and osteoporotic vertebral compression fractures increases significantly with age. Considering the difficulties in the diagnosis of spontaneous osteoporotic vertebral fractures, this retrospective study aimed to compare the characteristics of back pain in women with postmenopausal osteoporosis with and without vertebral compression fractures. MATERIAL AND METHODS This study enrolled 334 women with postmenopausal osteoporosis; 150 had vertebral fractures, and 184 had no vertebral fractures.

The Influence of Laparoscopic Sleeve Gastrectomy on Body Composition and Fat Distribution in Obese Caucasian Men and Women.

Background: The aim of the study was to assess changes in body composition in patients subjected to laparoscopic sleeve gastrectomy (LSG).

Methods: Changes in body composition following LSG were determined in a group of 155 patients with obesity (117 women and 38 men), with dual-energy X-ray absorptiometry (DXA). Whole body fat mass (FM) and lean body mass (LBM) were determined, and abdominal fat mass (AbdF) was assessed within the region extending from the top of the pubic bone up to the line between 12th thoracic and 1st lumbar vertebras.

Asymmetric Dimethylarginine (ADMA) and Symmetric Dimethylarginine (SDMA) Concentrations in Patients with Obesity and the Risk of Obstructive Sleep Apnea (OSA).

Asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) are endogenous inhibitors of nitric oxide (NO) synthesis, and play a critical role in the process of endothelial dysfunction, and are considered markers of oxidative stress. The aim of the present study was to explore relationships between ADMA and/or SDMA and the occurrence of OSA in obese patients as well as the effect of the endothelial nitric oxide synthase (eNOS) gene polymorphism, which may modify the influence of ADMA or SDMA on NO production. A total of 518 unrelated obese subjects were included in this study.

Age at onset of obesity, transcription factor 7-like 2 (TCF7L2) rs7903146 polymorphism, adiponectin levels and the risk of type 2 diabetes in obese patients.

Introduction: Interaction between obesity and genetic factors involved in the regulatory pathways of glucose homeostasis may play a significant role in diabetes development in the obese. The aim of this study was to investigate the associations between the TCF7L2 rs7903146 polymorphism, adiponectin levels, age at onset of obesity and the occurrence of type 2 diabetes (T2D) in a sample of obese Polish adults.

Material And Methods: A total of 474 unrelated obese subjects were included in this study.

Early Onset of Obesity and Adult Onset of Obesity as Factors Affecting Patient Characteristics Prior to Bariatric Surgery.

Background: Patients who are slated for bariatric surgery vary in terms of their age at onset of obesity, duration of obesity, and their health complications. Therefore, we aimed to explore a relationship between the age at onset of obesity, metabolic parameters, and health problems in bariatric surgery candidates.

Methods: A total of 469 unrelated adults with obesity prior to bariatric surgery were included in this study.

Impulsivity and vitamin D in bariatric surgery candidates.

Background: Obesity is recognized as a major health problem. Vitamin D is involved in maintaining energy metabolism by regulation of glucose transporters, uncoupling proteins, and normal brain function. We aimed to explore a relationship between impulsivity, eating behaviors, and 25-hydroxyvitamin D concentration in a sample of 322 bariatric surgery candidates.

Insomnia and depressive symptoms in relation to unhealthy eating behaviors in bariatric surgery candidates.

Background: Alongside obesity, insomnia and depression are common public health problems. Sleep problems are currently believed to be associated with excessive food intake and metabolic disturbances. Therefore, we aimed to explore a relationship between insomnia, depressive symptoms and eating habits as well as metabolic parameters in bariatric surgery candidates.

Practical guidelines for the supplementation of vitamin D and the treatment of deficits in Central Europe - recommended vitamin D intakes in the general population and groups at risk of vitamin D deficiency.

Introduction: Adequate Vitamin D intake and its concentration in serum are important for bone health and calcium-phosphate metabolism as well as for optimal function of many organs and tissues. Documented trends in lifestyle, nutritional habits and physical activity appear to be associated with moderate or severe Vitamin D deficits resulting in health problems. Most epidemiological studies suggest that Vitamin D deficiency is prevalent among Central European populations.

Switching from one generic alendronate to another--a common procedure in Poland in the years 2001-2005.

Introduction: In clinical ambulatory practice, patients often, rather than discontinuing treatment, change to another one. This study aims to assess the reasons why patients with osteoporosis switch from one alendronate to another with a different brand name.

Material And Methods: A retrospective analysis of 747 bisphosphonate-treated patients was performed (651 female, average age 67.

Vitamin D supplementation in adults - guidelines.

Vitamin D is necessary in maintaining appropriate calcium and phosphate homeostasis in the body (classical function) and ensuring appropriate functioning of many tissues, organs and cells, unrelated to mineral economy (non-classical function). Vitamin D deficiency in adults may cause osteomalacia, increase fracture risk in osteoporosis, induce cardiovascular diseases, diabetes type 1 and 2, multiple sclerosis, Lesniowski-Crohn disease, and cancer, including colon, breast, and prostate cancer. Possible causes of vitamin D deficiency in a healthy population include decreased cutaneous synthesis and an inadequate intake of vitamin D, both in food and in supplements.

The use of parathyroid hormone in the treatment of osteoporosis.

The primary goal in the treatment of osteoporosis is to prevent skeletal fractures. Modern antiresorptive drugs reduce the number of fractures in patients with moderate osteoporosis, but they cannot repair serious damage to bone structure. Both experimental investigations and clinical trials have shown that daily injections of parathyroid hormone or its amino-terminal fragment (1-34) increase the number and activity of osteoblasts, and accelerate formation of new bone tissue.

[Administration of 1 alpha-OH vitamin D3 and calcium prevents bone mass loss in patients with advanced prostatic carcinoma after orchidectomy treated with complete androgenic blockade].

Unlabelled: Complete androgenic blockade used in the treatment of advanced prostatic carcinoma can be attained by administration of antiandrogens in orchidectomized patients or by combined therapy with LH-RH analogs and antiandrogens. The treatment, however, decreases the influence of both androgens end estrogens on bone tissue and may result in bone mass loss and increased propensity to fractures. The purpose of the study was to determine the influence of complete androgenic blockade on bone mass and skeletal metabolism in men with advanced prostatic carcinoma and to assess whether 1alpha-OH vitamin D3 (1alpha-OHD3) together with calcium supplementation is able to prevent bone mass loss in men treated with complete androgenic blockade.
