Determination of vitamin D, iron and n-3 fatty acids in adolescents with different eating habits.

Objectives: Proper eating habits ensure human health, so it is important to eat a balanced diet and learn the basics of proper eating from an early age. Adolescence is considered very important period for maintaining good health in terms of nutrition.

Methods: In the study, we monitored the eating habits of 182 adolescents aged 14-19 years with different eating habits (73 vegetarians and 109 nonvegetarians) using a questionnaire on nutrition and determination of selected blood parameters - vitamin D, iron and n-3fatty acids.

Eighteen-Year Effect of Androgen Therapy on Bone Mineral Density in Trans(gender) Men.

The study explores the influence of long-term androgen supplementation (18 years) on bone metabolism in trans(gender) men. Thirty five trans(gender) men aged (47±4) were treated with adequate dose of testosterone. BMD was measured by DEXA at lumbar spine and neck and T score was determined.

Selected Cardiovascular Risk Markers in Vegetarians and Subjects of General Population.

Objective: Besides genetic factors there are environmental effects including nutritional habits which can influence the risk of age-related diseases. The aim of the study was to assess the age dependence of selected cardiovascular risk markers in two groups of subjects with different nutritional pattern.

Methods: In 470 long-term vegetarians and 478 subjects of general population the following indicators were measured: total cholesterol, HDL-cholesterol, triacylglycerol, glucose, insulin concentrations, LDL-cholesterol, atherogenic index and insulin resistance IR(HOMA) were also calculated in studied subjects.

Chemotherapy for acute myeloid leukemias with cytosine arabinoside, daunorubicin, etoposide, and mitoxantrone may cause permanent oligoasthenozoospermia or amenorrhea in middle-aged patients.

The aim was to follow-up gonadal functions in long-term survivors of acute myeloid leukemias (AML) after intensive chemotherapy based on high-doses of cytosine arabinoside (Ara-C) and anthracyclines in the study UHKT-911. Adult patients were treated with at least 3 cycles of chemotherapy including 1-3 courses of Ara-C 10 x 2000 mg/m2/12 h and daunorubicin (DNR) 2 x 45 mg/m2/d. Spermiologic examinations were performed in 7 men by the classic microscopic method and results were evaluated according to the WHOcriteria.

[Josef Hynie (1900-1989)--100 years since the birth of the founder of Czechoslovak sexology].

The anniversary of one hundred years from the birth of Josef Hynie, the renowned professor of Charles' University and pioneer of medical sexology, is an impulse for thinking again about his lifelong successful creative activities, namely clinical, scientific, publication, teaching and sexual-educational activities. At the Faculty of Medicine in Prague Hynie enforced and built the first university sexological institute in the world and achieved its general recognition. With the team of his pupils for years he integrated the behavioral and reproduction aspects of the branch and thus predetermined its wide conception also for the future generations of Czech sexologists.

[Treatment of gynecologic inflammations in Frantiskových Lázních Health Spa].

In 36 patients treated on account of chronic inflammations of the genitals a check-up examination was made 5 to 6 months after termination of spa treatment. Attention was paid to the gynaecological palpation finding, the mental state of the patients and their sex life. It was found that the palpation finding improved markedly or became normal (p < 0.

[Psychologic causes of erectile dysfunction].

The authors discuss the most frequent psychological causes of impaired erectility. The most important psychogenic factors for the development and persistence of erectile impairment is in their opinion anticipative anxiety, performance orientation, the partner's negative reaction to rare failure, the observer's attitude, antisexual upbringing, monotony of sexual intercourse, persisting sexual myths and unsuitable attitudes, impaired communication of the couple, different sexual preferences,psychic and sexual traumas and pathological mental conditions. However, as personality characteristics of the patient and the quality of his partnership may play a decisive part in the development of this disorder the authors feel that it is a mistake to confine the diagnosis and treatment only to the area of sexual reactivity and sexual behaviour.

[Effect of treated genital cancer on sexual functions of the woman].

By means of a structured interview and four questionnaires (Heterosexual development of woman, Sexual activity of woman, Sexual function of woman and Questionnaire N5 which evaluates the presence and intensity of neurotic symptoms) the authors examined 163 women following treatment of a malignant tumor of the genitalia. The examination was made during balneological therapy in a spa. Their age varied between 20 and 63 years.

[Personality characteristics of men with psychogenic erectile dysfunction].

Based on psychological examination of 47 males with the diagnosis of psychogenic erectile dysfunction, the following personality characteristics were defined by the authors as typical of these patients: 1. a high level of anxiety and neuroticism, 2. reduced masculinity in the partnership, 3.

[Sexuality in women after treatment of malignant genital tumors].

Using a structured interview and four questionnaires (Heterosexual development of woman, Sexual activity of woman, Sexual function of woman and questionnaire N5 which is used to evaluate the prevalence and intensity of neurotic symptoms, the authors examined 163 women after treatment of a malignant tumour of the genitalia.

[Sexual function in women with breast carcinoma in relation to the time interval after mastectomy].

Within the framework of more extensive research in a group of women after treatment of breast cancer the authors paid attention also to changes of sexual function in relation to the time which elapsed after ablation (modified radical mastectomy). 151 patients replied to the question pertaining to changes of the general status of sexual intercourse after treatment of carcinoma, as compared with the year preceding establishment of the diagnosis. With regard to their replies the probands were divided into four sub-groups: A-paradoxical improvement of sexual life (n = 12, 7.

Correlation of asthenozoospermia with increased antisperm cell-mediated immunity in men from infertile couples.

To investigate whether cell-mediated immunity (CMI) against sperm and/or antisperm circulating antibodies are associated with poor semen quality, a leukocyte migration inhibition factor (LMIF) assay and an enzyme-linked immunosorbent assay (ELISA) were performed in groups of men from infertile couples, men from fertile couples and sperm donors. Twenty-five of 102 men (25%) revealed positive CMI against sperm and 10 (10%) had positive antisperm antibody titers in their sera. Fifteen of 28 asthenozoospermic men (53%) from infertile couples revealed positive antisperm CMI.
