Background. Osteoporosis is a disease characterized by decreased bone density and destruction of bone microarchitecture. Indicators for altered bone homeostasis are changes in the serum level of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). The purpose of the current study was to evaluate the effect of a 12-week exercise program on enzyme activity of serum MMP-9 and TIMP-1 in postmenopausal osteoporotic patients. Materials and methods. Participants were randomized in two groups: exercise (EG) (N = 37) and control (CG) (N = 31). The exercise group completed a 12-week supervised exercise program, while the control group did not take part in any physical activity. Enzyme activities of serum MMP-9 and TIMP-1 were detected by gelatin zymography and ELISA in both groups, respectively. Results. Significant differences between pretreatment and posttreatment enzyme activities of serum MMP-9 (p=0.009), TIMP-1 (p≤0.001), and MMP-9/TIMP-1 ratio (p≤0.001) were detected in the exercise group. Exercises decreased the activity of serum MMP-9 and increased the activity of TIMP-1, while the enzyme activities of MMP-9 (0.583) and TIMP-1 (0.210) have not been significantly changed in CG. Patients from the exercise group had better treatment. Conclusion. Our results suggest that a 12-week exercise program has an influence on enzyme activity of serum MMP-9, revealing a possible role of MMPs in initiating training-specific adaptation. Although measurements of circulating MMP-9 and TIMP-1 allowed us to detect effects of exercise, as of today, they have no real role in the diagnosis of osteoporosis and/or follow-up of osteoporotic patient’s response to treatment. MMP-9 might be used as an important prognostic marker for the evaluation of patient’s response to exercise. Larger-randomized controlled studies need to be performed to expand this area of knowledge. This trial is registered with trial registration number: NCT03816449).
The aim of this study was to compare the success of surgical procedures performed by laparoscopy and laparotomy in the treatment of tubal ectopic pregnancy. Materials and Methods: In this prospective study, there were 57 women who were operated due to tubal ectopic pregnancy. Laparoscopic surgery was performed in 36 women (study group). Conventional abdominal surgical treatment was performed in 21 women (control group). Results: Among 36 women from study group, a laparoscopic linear salpingotomy was performed in 69.44% cases, salpingectomy in 13.88% cases, and milking of tube in 16.66% cases. In the control group, linear salpingotomy was performed in 57.14% cases, salpingectomy in 28.57% cases, and milking of tube in 14.28% cases. Patent ipsilateral fallopian tube at three months after surgery was 66.66% in the study group and 52.38% in the control group. The intrauterine pregnancy rate was 19.44% in the study group and 19.05% in the control group. Conclusion: The percentage of tubal patency and intrauterine pregnancies after laparoscopical surgical treatment was not higher than after conventional surgical treatment by laparotomy.
Background and Objectives: The aim of this study was to validate the Serbian version of the Boston Carpal Tunnel Questionnaire (BCTQ) and to evaluate temporal stability for the purpose of its implementation in the evaluation of Serbian patients with carpal tunnel syndrome (CTS). Materials and Methods: For the validation of the Serbian version of the BCTQ (BCTQSR), we tested 69 individuals with diagnosed CTS that were referred for a conservative treatment at the Institute for Rehabilitation. Neurophysiological tests were used for the electrophysiological grading (EG) of CTS severity in the study sample. The final version of the BCTQSR was given to the tested participants from the study on two occasions: test and retest, with a five-day period between the two measurements. Results: The mean value for the symptom severity subscale (SSS) of the BCTQSR was 3.01 ± 0.94; for the functional status subscale (FSS) of the BCTQSR it was 2.85 ± 1.00. Cronbach’s α for the SSS was 0.91 and 0.93 for the FSS. The intraclass correlation coefficients (ICCs) concerning the test–retest were significant (p < 0.001) and were 0.949 for the SSS and 0.959 for the FSS. Those with a higher EG grade had higher values of the SSS and FSS but without a statistical significance (p = 0.103 and p = 0.053, respectively). The intercorrelation of the BCTQSR subscales (SSS and FSS) on the test was significant (p < 0.001) with a correlation coefficient equal to 0.777. Conclusion: The Serbian version of the BCTQ (BCTQSR) was successfully culturally adopted. The BCTQSR was a valid and reliable instrument for the measurement of symptom severity and functional status in adults with CTS. Therefore, it can be used in clinical practice for patients with CTS.
Febrile seizures (FS) are the most common neurological disorder in childhood and are a great stress for parents due to their dramatic clinical appearance. Using test for determination of homozygously recessive characteristics in humans (HRC test) we analyzed presence, distribution, and individual combination of 20 selected genetically controlled morphophysiological traits among FS patients (N=121) and control (N=121) to determine a possible deviation in the homozygosity level and genetic loads in the group of affected children and whether there is a predisposition to the occurrence of FS. The results of our study show a statistically significant difference in the mean values of the HRC tested (x¯HRC/20 CN = 3.2 ± 0.2; x¯HRC/20 FS = 4.6 ± 0.2, t= 5.74 , p< 0.0001), as well as in the distribution and variability of two studied samples (VC=55,3%, VFS= 39,6%), which indicates a complex polygenic difference among the tested groups of subjects. The differences in the degree of genetic homozygosity and variability are also present between the genders (t Cf/FSf = 4.12; t Cm/FSm = 3.98; p <0.0001) (VCf=56.9%, VFSf= 39.3%; VCm=54.1%, VFSm=40.1%). Obtained results indicate the enlargement of recessively homozygous genetic loads in the group of children with FS which may represent some kind of predisposition for expressivity of this type of seizures.
