AbstractPurpose. Increasing anthropometric measures bring considerable spinal loads during sports practice, which inversely affects the adaptation abilities of the spinal structures; this in turn influences the spinal curvatures. The study was conducted to explore the relationship between anthropometric measures and sagittal spinal curvatures in handball players. Method. The total of 83 male handball players were divided into 2 groups, depending on their body height: group 1 (age, 23.62 ± 2.07 years) consisted of 40 handball players with height above average, group 2 (age, 24.63 ± 2.58 years) consisted of 43 handball players with height below average. The thoracic and lumbar curvatures and trunk height were measured with the Formetric III 4D spine and posture analysis system. Results. The thoracic kyphosis of group 1 was significantly higher than that of group 2 (p = 0.038), without a significant difference in lumbar lordosis (p = 0.312), and significant difference in the coefficient of compensation between thoracic kyphosis and lumbar lordosis (p = 0.026). Group 1 showed strong positive correlation between body height and kyphotic angle (r = 0.897), and moderate positive correlation with lordosis angle (r = 0.496). In group 2, there was weak positive correlation with kyphotic angle (r = 0.381), and weak negative correlation with lumbar lordosis angle (r = -0.355). Conclusions. Increasing body height of handball players is associated with bigger kyphotic and lordotic angles. Owing to frequent sagittal asymmetric overloading of the spine during handball training, exercises that help maintain good posture and correct the thoracic kyphosis are required, especially for taller players.

Abstract Abstract: There is a positive correlation between serum 25 (OH) Vit D concentrations below 30 ng/ml and the incidence of preterm delivery, while higher levels can bring benefits to pregnancy. Although studies agree that TSH levels affect fertility, in euthyroid women (0.5<TSH<4.5), the serum concentration of this hormone still has a dubious effect on gestational outcomes. In order to study the relationship between vitamin D, TSH levels and pregnancy endpoint, a retrospective cohort study was conducted that considered 520 women who had undergone In-Vitro Fertilization (IVF). Patients were grouped regarding TSH values in mIU/L: 0.5-2.49 (Group 1) (n=416) and 2.5-4.5 (Group 2) (n=104), the serum levels of 25 (OH) Vit D within them were dichotomized in subgroups: <30 ng/mL (Group 1, n=212; Group 2, n=49) and >30 ng/mL (Group 1, n=204; Group 2, n=55). Primary endpoint was clinical pregnancy (the presence of the gestational sac and fetal heartbeat by ultrasound) and secondary outcomes were miscarriage and gestacional age (preterm or full-term pregnancy). The rate of clinical pregnancy in group 1 was significantly higher in patients with 25 (OH) Vit D <30 ng/ml (51.9%) than 25 (OH) Vit D >30 ng/ml (42.2%) according to the chi-square test and Fisher’s exact test (p<0.05 all). There was no significant difference in group 2 (p=0.35), with percentages of 49% and 40% in the respective subgroups. Moreover, no statistical difference between the abortion rates was seen in 25 (OH) Vit D subgroups in groups 1 (p=0.71) and 2 (p=0.52). When gestational age rates were measured, the percentage of full-term pregnancies was lower in patients with 25 (OH) Vit D <30 ng/ml (Group 1=62.6%; Group 2=57.9%), compared to those with 25 (OH) Vit D >30 ng/ml (Group 1=77.6%; Group 2=78.9%), however, only the subgroups in the TSH category between 0.5-2.49 mUI/L showed a statistically significant difference (p<0,05). The Spearman test identified a weak positive correlation between 25 (OH) Vit D and gestational age (ρ=0.218; p<0.05). The findings indicate lower frequency of clinical pregnancy in patients with TSH between 0.5-2.49 mIU/L and 25 (OH) Vit D >30 ng/ml. In addition, variations in 25 (OH) Vit D, in both TSH groups, do not suggest interference in miscarriage rates. Furthermore, higher serum concentrations of 25 (OH) Vit D seem to be involved with an increase in the prevalence of full-term births, an important finding to guide the procedures for IVF.

Abstract Objective : The human body is characterized by the variability of the characteristics of body build, which is expressed in the instability of spinal curvatures, which change during ontogeny. This phenomenon leads to a phylogenetic evolution of the human body build and posture. The aim of the study was to assess the dynamics of the variability of traits and indices of body build and posture and their mutual relations. It was assumed that over the 10-year observation period, a significant variability and relationships will be observed between the characteristics of body build and posture in young adults. Material and Methods: Between 2006 and 2016, 2,154 women and men aged 19.6±0.8 were examined (first-year students of the University of Economics in Katowice, Poland). Measurements of basic anthropometric measurements and angular values of lumbar lordosis and thoracic kyphosis were performed. The collected data were analysed statistically and the intergroup and intragroup differences were evaluated (ANOVA with repeated measures). The dynamics of variability (by building time series) and absolute and single-base increments were determined. Results : The body build of young men and women in the period of ontogenetic stabilization in the study group has changed statistically significantly over the decade. A prediction of the increases in body weight and hip circumference was recorded over a period of 10 years, especially in men. The characteristics of body posture have also undergone a significant progressive change. In women, thoracic kyphosis increased by 96.15%, whereas in men, lumbar lordosis decreased by 52.65%. Conclusions : Significant sexual differentiation was shown for such characteristics as body height, waist circumference and the angle of lumbar lordosis. The relationships between the characteristics of body build and posture were verified. There was a moderate relationship between the hip circumference and lumbar lordosis in women and a weak relationship between body height and the angle of thoracic kyphosis in men.The characteristics of human body build and posture during the period of ontogenetic stabilization show high non-linear variability, characterized by significant dimorphic differentiation.

Purpose The angles of thoracic kyphosis and lumbar lordosis determine the spinal alignment in the sagittal plane. The aim of this study was to compare the thoracic kyphosis and lumbar lordosis of male and female yoga practitioners with non-practicing participants and to determine the possible dependencies between sagittal spinal curvatures and somatic parameters, time spent on yoga exercise, and undertaking other physical activities in yoga practitioners. Methods The study involved 576 women and 91 men ages 18–68 years (mean = 38.5 ± 9) who were practicing yoga, and 402 women and 176 men ages 18–30 years (mean = 20.2 ± 1.3) as a control group. The angles of thoracic kyphosis and lumbar lordosis were measured using a Plurimeter-V gravity inclinometer. Results The two-way ANOVA demonstrated the influence of group (p < .0001) and sex (p = .03) on the angle of thoracic kyphosis, as well as the influence of group (p < .0001) and sex (p < .0001) on the angle of lumbar lordosis. It was noted that yoga practitioners had less pronounced thoracic kyphosis and lumbar lordosis and were more often characterized by normal or smaller thoracic kyphosis and lumbar lordosis than students from the control group. In yoga practitioners, the angle of thoracic kyphosis was positively correlated with age, body mass, BMI, and undertaking other forms of physical activity. The angle of lumbar lordosis was negatively correlated with body height and body mass. Conclusions The results suggest that yoga exercises can affect the shape of the anterior-posterior curves of the spine and may be an efficient training method for shaping proper posture in adults.

BACKGROUND: One of the complications of obesity is low back pain, frequently associated with postural disorders. Body adiposity index (BAI) can be calculated without weighing, which may be rendered useful in settings where measuring accurate body weight is problematic. OBJECTIVE: The aim of this study was to compare two indices of somatic structure, i.e., BAI and BMI regarding their accuracy (specific and sensitive) in predicting postural aberrations. METHODS: The study group comprised of 1281 participants aged 20–22 years, who were students from universities in southern Poland. Anteroposterior spinal curvatures were measured using the Rippstein plurimeter. All subjects were measured for body height (BH) and mass, waist and hip circumference (WC and HC, respectively). RESULTS: In both male and female groups classified according to BAI cut-off points, a significant linear relationship was noted for the lumbar lordosis angle, i.e., the latter increased along with the BAI increase. The analysis of variance confirmed statistically significant differences in lordosis angles in both groups (women f= 19.6, p< 0.001; men f= 21.18, p< 0.001). These data evidenced a weak relationship between LL and the BAI. Pearson correlation coefficient (r) between LL and BAI was 0.2 and 0.21 for men and women, respectively. CONCLUSIONS: We concluded that, contrary to BAI, BMI value did not indicate a significant difference in lumbar lordosis angle between normal weight and obese participants (women and men).

Abstract Purpose Aim of this study was to compare the reconstruction of radiological sagittal spinopelvic parameters between lordotic (10°) and normal cages (0°) after dorsal lumbar spondylodesis. Methods This retrospective monocentric study included patients who received dorsal lumbar spondylodesis between January 2014 and December 2018. Inclusion criteria were degenerative lumbar diseases and mono- or bi-segmental fusions in the middle and lower lumbar region. Exclusion criteria were long-distance fusions (3 segments and more) and infectious and tumour-related diseases. The sagittal spinopelvine parameters (lumbar lordosis, segmental lordosis, sacral slope, pelvic incidence, and pelvic tilt) were measured pre- and post-operatively by two examiners at two different times. The patients were divided into 2 groups (group 1: lordotic cage, group 2: normal cage). Results One hundred thirty-eight patients (77 female, 61 male) with an average age of 66.6 ± 11.2 years (min.: 26, max.: 90) were included in the study based on the inclusion criteria. Ninety-two patients (66.7%) received 0° cages and 46 (33.3%) lordotic cages (10°). Segmental lordosis was increased by 4.2° on average in group 1 and by 6.5° in group 2 (p = 0.074). Average lumbar lordosis was increased by 2.1° in group 1 and by 0.6° in group 2 (p = 0.378). There was no significant difference in the correction of sagittal spinopelvic parameters. Inter- and inter-class reliability was between 0.887 and 0.956. Conclusion According to the results of our study, no advantages regarding sagittal radiological parameters for the implantation of a lordotic cage could be demonstrated.

SummaryStudy aim: The aim of this study was to assess and compare the posture of male and female adolescent volleyball players and non-training individuals over a 2-year period.Material and methods: The study group comprised 32 volleyball players and 30 non-athlete peers. Posture was assessed with a photogrammetric method based on the moiré phenomenon. Participants were examined 3 times at the ages of 14, 15 and 16 years. Training experience of the studied volleyball players at the time of the 1st measurement was less than 5 months.Results: In volleyball players greater asymmetry in the pelvis position was noted (rotation to the right). The right scapula was more outlying than the left, and the right shoulder was more elevated than the left. Volleyball training did not result in sagittal spinal curvatures. Male non-athlete participants exhibited a significant increase in thoracic kyphosis and a decrease in lumbar lordosis over a two-year period.Conclusion: Volleyball training affects the alignment of the pelvis, shoulder girdle and scapulae. The study revealed a number of differences in spinal curvatures between male volleyball players and non-athletes which could be associated with growth velocity and differences in body height.

AIM: There are no reports regarding the influence of vitamin D on thymosin ß4 and the cluster of differentiation CD4 levels which are important for maintaining a healthy immune system. Consequently, we aimed to explore this relationship through a study.MATERIAL AND METHODS: The study was carried out on 35 subjects, screened for 25-hydroxy vitamin D[25 (OH) D] using ELISA method and they were divided into two groups: Group 1 consists of 10 healthy subjects with sufficient vit. D level > 24.8 ng/ml. Group 2 consists of 25 subjects suffering, severely, from vitamin D deficiency at level < 11.325 ng/ml. Also, Thymosin ß4, CD4 and zinc levels were performed.RESULTS: There were significant differences between the two groups in the concentration levels of thymosin β4, as the group 1 has shown higher levels (P = 0.005). Whereas, CD4 and zinc levels didn’t show any significant difference between the two groups. At the same time, a significant positive correlation has been observed between vitamin D, thymosin β4, and CD4 at (r = 0.719; P = 0.001), and (r = 0.559, P = 0.001) respectively.CONCLUSION: We concluded that vitamin D may be an essential factor that influence or determine the level of thymosin β4. This study is the first that focused on demonstrating that sufficient level of vitamin D may have the ability to influence the thymic hormone thymosin β4 levels. Further studies on large scale of subjects are needed to explore the positive correlation we had found between vitamin D and thymosin β4 and CD4.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

The clinic and diagnostics of tuberculosis meningitis (TM) in 926 patients treated in St. Petersburg hospitals in 1965–1994 (group 1) and in 1995–2018 (group 2) is presented. The TM clinic is demonstrated to be determined by the form of tuberculosis and its characteristic generalization nature in the presence of repeated waves of bacteremia and allergic vasculitis of greater or lesser severity. There is clinical peculiarity of TM in primary pulmonary tuberculosis and its early large-focal and late miliar generalization, as well as in hematogenous tuberculosis. In patients of the 1st and 2nd groups the TM clinic shows in some respects a noticeable similarity, in others — a significant difference. Despite the typical symptoms, early diagnosis of TM took place in less than 20% of patients. Clinical examples illustrating the unusual development of TM, contrasting with its usual course, are given. A number of objective and subjective factors contributing to the adverse evolution of TM and its lethal outcome are discussed. These include the peculiarity of modern tuberculosis, especially when associated with HIV infection, as well as medical errors associated with ignorance of the pathogenesis of tuberculosis and failure to comply with the minimum examination for tuberculosis.
