    Opis:
    In recent years, attention has been focused on pleiotropic directions of effects exerted by vitamin D. Epidemiological data indicate that deficiency of vitamin D in various population groups represents an increasingly widespread phenomenon, while a decreased serum concentration of calcitriol correlates with manifestation of civilization-linked diseases, including visceral obesity. This study aims at a review and synthesis of data linked to relationships between lowered vitamin D concentrations in blood and manifestation of obesity, and potential mechanisms which affect the concentration of the vitamin in conditions of an excessive accumulation of adipose tissue. Several variables are distinguished which can affect the status of vitamin D in obesity, but the key role in this respect is ascribed to the metabolic activity of visceral adipose tissue. Among others, the activity favours sequestration and modulation of calcitriol turnover. On the other hand, the effects of vitamin D on the process of adipogenesis and its involvement in remodelling of adipose tissue are pointed out. Also, several factors of an environmental nature (e.g. time of year/day, dietetic supply of vitamin D), genetic nature (e.g. genetic polymorphisms) and other conditioning (e.g. coexisting diseases, age, content of melanin in skin) cannot be bypassed as they may affect the concentration of vitamin D. Nevertheless, it still remains unresolved to what extent hypovitaminosis D represents the cause and to which it is the effect of obesity.

    Opis:
    Introduction and objective. Since the role of vitamin D is essential in numerous biological processes its deficiency was suggested to be a risk factor for e.g. osteoporosis, musculoskeletal pain and spine pain. The purpose of the study was to analyse whether serum vitamin D concentration is related to pain involving the motor system in Polish postmenopausal women working in agriculture. Material and methods. The study group consisted of 1,751 post-menopausal women, aged 45–65, at least 12 months from the last menstrual period, living in rural areas and working in agriculture. The research method was self-assessment of pain involving the motor system using VAS, laboratory test of serum vitamin D concentration and a medical interview. Statistical methods included generalized linear models, analysis of variance, t test for two means in two independents, χ2 test of stochastic independence. Results. Postmenopausal women working in agriculture and suffering from pain in at least one part of the motor system were younger and lower educated, they also had higher abdominal obesity and lower serum vitamin D, compared to those without pain in any part of the motor system. Decreased serum vitamin D concentration in postmenopausal women working in agriculture is important from the aspect of a higher prevalence of pain in the thoracic spine and more severe pain in the neck spine, but not for severity of pain in the lumbar spine; higher occurrence of pain in both hands or wrists; higher prevalence and more severe pain in at least one knee; and no prevalence or severity of pain in the shoulders and elbows. Conclusion. Serum vitamin D concentration is important for the prevalence and severity of pain in the neck and thoracic spine, knees and hands or wrists, but not for the lumbar spine, shoulders and elbows.

    Opis:
    Vitamin D is essential for the proper functioning of the human body. There is also evidence of its strong association with fertility problems in women. This review aims to evaluate the relationship between vitamin D and diseases affecting women’s fertility (polycystic ovarian syndrome (PCOS), uterine leiomyomas and endometriosis), and in vitro fertilization (IVF) outcome. A systematic review of the literature was conducted in Scopus and PubMed for relevant English language publications since 1989. Vitamin D influences the functioning of the reproductive system in women and has been associated with PCOS, uterine leiomyomas, endometriosis and in vitro fertilization (IVF) outcome. However, further studies on larger groups of patients are needed to establish what role vitamin D plays in the treatment of female infertility.

    Opis:
    Introduction and objective. Deficits of vitamin resources constitute a significant public health problem, especially among the elderly population. The aim of the research was to determine the level of vitamin 25 (OH) D and vitamins from group B in the chronically ill elderly in domiciliary care, depending on functional capacity and coexisting diseases. Materials and method. The pilot study included 137 patients staying in long-term domiciliary care. Samples of the participants’ venous blood was obtained for laboratory tests. Centrifuged serum was used to determine the level of the following biochemical parameters: vitamin 25 (OH)D, B12, folic acid and total protein, albumin, triglycerides, total cholesterol and HDL cholesterol. Assessment of the functional status of patients was made by using the Barthel scale. Results. More than 3⁄4 of the patients with functional deficit (according to Barthel’s score 0–85 points) were deficient in vitamin 25 (OH)D, while folic acid values were below the reference values in more than half of the patients. Respondents with lower functional efficiency were characterised by a reduced average value of vitamin 25 (OH)D and folic acid. Conclusions. The studied group of the chronically ill elderly was characterised by a deficiency of vitamin D3 and folic acid. Subjects with a functional impairment deficit show a reduced mean value of vitamin 25 (OH)D and folic acid in the blood serum, compared to the group of patients with higher mobility.
