Comparison of performance and anthropometric parameters in paediatric competitive athletes during COVID-19 pandemic in the Czech Republic.

Objectives: In 2020, measures against the spread of COVID-19 were adopted, including nationwide school closures, restrictions on the free movement of persons and leisure time sports activities. The aim was to assess the impact of COVID-19-associated restrictions on the performance of paediatric and adolescent competitive athletes by comparing basic anthropometric and performance parameters.

Methods: The sample comprised 389 participants (115 girls, 274 boys).

Evaluation of insulin resistance and metabolic syndrome in a group of obese Czech children.

Objective: The study aimed to determine the incidence of metabolic syndrome (MS) in a group of Czech obese children, to evaluate the incidence of insulin resistance according to HOMA-IR in this group, and to consider the diagnostic value of HOMA-IR in early MS detection in obese children using the logistic regression models for analyzing the relations between HOMA IR and MS.

Subjects And Methods: Anthropometric and laboratory examinations were performed in a group of 274 obese children aged 10-17 years.

Results: MS was established in 102 subjects (37%).

Relationship between reactive oxygen species production in human semen and sperm DNA damage assessed by Sperm Chromatin Structure Assay.

Aim: The aim of this prospective study was to find possible relationship between ROS production measured by chemiluminescence and flow cytometry in human semen and sperm DNA damage estimated by Sperm Chromatin Structure Assay.

Methods: Study included 39 men from infertile couples and 23 fertile volunteers who served as a control group. Aliquot of neat semen was used for ROS detection by chemiluminescence.

Lycopene improves the distorted ratio between AA/DHA in the seminal plasma of infertile males and increases the likelihood of successful pregnancy.

Aims: Male infertility has been associated with imbalance in the polyunsaturated fatty acids arachidonic acid/docosahexaenoic acid (AA/DHA) ratio. This study aimed to assess whether use of the potent antioxidant, lycopene, would affect this imbalance in seminal plasma and to test whether modulation of the AA/DHA ratio correlates with male fertility.

Methods: The study included 44 males from infertile couples who were treated with lycopene for three months before scheduled IVF treatment.

Dehiscent scar in the lower uterine segment after Caesarean section and IVF infertility treatment: a case report.

Aims: Caesarean section is the most common obstetric operation associated with short and long term risks, one of which is uterine scar dehiscence. In this case report we describe four cases of in vitro fertilization and embryo transfer (IVF+ET) treatment where the embryo was transferred into the uterus with known scar dehiscence in the lower uterine segment after a previous Caesarean section (SC).

Methods: All transfers of embryos were ultrasound guided directly into the middle of uterine cavity.

Clinical anatomy aspects of functional 3D training -- case study.

Introduction: Functional 3D training originating in rehabilitation and physiotherapy routines, is modelled on the basis of a patient's functional impairment and muscle function test results. 3-D functional rehabilitation comprises two key components. The first is three-dimensional movements of the body and the second is restoration of function, The aim of 3D training is not only to improve physical fitness and muscular coordination, it is recommended for all age groups regardless of health status.

A randomized controlled trial of lycopene treatment on soluble receptor for advanced glycation end products in seminal and blood plasma of normospermic men.

Problem: The aim of present study was to investigate the effects of antioxidant lycopene on soluble receptor for advanced glycation end products (sRAGE) levels in blood and seminal plasma in normospermic males.

Methods: Study included 15 fertile volunteers and 13 normospermic male partners from infertile relationships. The treatment was 12-week administration of 20 mg of lycopene or placebo followed by crossover and treatment for a further 12 weeks.
