The comparison of two different embryo culture methods in the course of in vitro fertilization program.

The objective of the study was to compare two different embryo culture methods in the course of in vitro fertilization program by means of fertilization rate, embryo development, total time and cost. 98 patients undergoing assisted reproduction procedures due to infertility were analyzed. The inclusion criteria for the study: first IVF-ET program, at least 10 MII oocytes, no indications for ICSI. Oocytes were divided into two study groups: group A- open culture (oocytes placed in four-well dishes together, then inseminated and cultured in successive wells) and group B - a closed culture (oocytes placed in microdroplets, each embryo cultured separately). The fertilization rate was assessed around 18 hours from insemination. The embryos were classified into four classes. The best embryos were chosen for transfer. In the group A the fertilization rate obtained was lower than in group B (68% vs. 78%, respectively). The microdroplet culture required more time on the insemination day and on the second day of culture, while the four-well dish method required more time on the first day of culture and on the day of transfer. On analyzing the total cost of the above procedures (MI medium and oil costs) it occurred that the microdroplet culture was more expensive than the four-well dish method (due to the intake of paraffin oil). However, the difference was of no practical importance. In the conclusion, microdroplet culture gives a higher fertilization rate than four-well dish culture, probably due to a homogenous sperm distribution. Despite the differences in time outside the incubator and laboratory expenses (which are after all insignificant) microdroplet culture allows a better control over the embryo development. The embryos of best developmental potential can therefore be chosen for ET

Cerebral amyloid angiopathy-related inflammation – A case report presenting diagnostic difficulties

We describe an 86-year-old woman with a history of hypertension who presented sudden disturbances of consciousness and left hemiparesis. Brain magnetic resonance imaging (MRI) revealed diffused hyperintensive changes on T2-weighted images localized subcortically in the white matter of both cerebral hemispheres, corresponding to acute vasogenic edema, causing moderate mass effect. Posterior reversible encephalopathy syndrome was initially diagnosed. After implementation of anti-edema intravenous steroid treatment and hypotensive therapy the symptoms began to retire, till the total regression. The successive hospitalizations took place two and eight months later due to the occurrence of seizures, motor deficits and the development of mild cognitive impairment. Brain MRI revealed progression of the white matter changes and diffused subcortical microhemorrhages. Each time pulse steroid therapy was implemented and the symptoms improved significantly after several days. Chronic oral steroid treatment resulted in the stabilization of neurological status. The long-term observation of clinical symptoms, remission after immunosuppressive therapy and white matter changes with subcortical microhemorrhages in brain MRI leaded to the diagnosis of cerebral amyloid angiopathy-related inflammation

The role of metalloproteinases in endometrial remodelling during menstrual cycle

Endometrium is the only tissue in the human body subject to cyclic transformations under the influence of ovarian steroid hormones. As estradiol and progesterone balance throughout the physiological menstrual cycle changes, so does the expression of metalloproteinases (MMPs). These endopeptides are responsible for keeping the balance between the process of synthesis and degradation of extracellular matrix proteins. Thus, MMP’s take part in sustaining physiological stability of the endometrium. A number of MMPs found in the endometrial tissue and their activity is related to menstrual cycle phase. This paper is an up-to-date review of literature of Medline database. The search was conducted for key words including “matrix metalloproteinases”, “MMPs”, “TIMPs” and “tissue inhibitors of metalloproteinases”. Over 1092 publications regarding interdependence and interplay between ovarian hormones and the role of various MMPs and their inhibitors in normal endometrial remodelling and in pathological conditions were analysed and critically reviewed

The association between serum metalloproteinase concentration, obesity, and hormone levels in reproductive-aged women

Introduction: Increased levels and activity of some matrix metalloproteinases (MMPs) are described in obesity-related vascular diseases. Factors that influence MMP blood concentration are still being investigated. This research aims to evaluate the concentration of most types of MMPs: collagenases (MMP-1, -3, -8, -13), matrilysin (MMP-7), gelatinase (MMP-9), and metalloelastase (MMP-12) in serum of women in reproductive age in relation with their body mass index (BMI), age, oestradiol, and progesterone concentrations. Material and methods: Blood samples were taken from 54 healthy reproductive-aged women with normal menstrual cycles. The weight and height of all women were measured, and body mass index (BMI) was calculated. Concentration of MMP-1, -3, -7, -8, -9, -12, and MMP-13 was evaluated using a Procarta Immunoassay Kit. Serum concentrations of oestradiol and progesterone were evaluated by immunochemiluminescence (32 in the proliferative and 20 in the secretory phase of menstrual cycle). The results of the study were statistically calculated using Pearson, Spearman, and Kruskal-Wallis tests. Results: Positive correlation between MMP-7, -8, -9, -12, and -13 levels and BMI was demonstrated. Significantly higher concentrations of MMPs were found especially in obese women compared to women with normal BMI. In healthy, regularly menstruating premenopausal women, MMP levels did not correlate with oestradiol and progesterone concentrations. Conclusions: The results suggest that body mass can influence MMP serum concentration in women with regular menstrual cycles

Matrix metalloproteinases-2, -7 and tissue metalloproteinase inhibitor-1 expression in human endometrium

Introduction. Endometrium undergoes regular, cyclic tissue remodeling mostly associated to the endocrine system status. It is well-known fact that steroid hormones are strongly responsible for changes in endometrium. The precise mechanism of their action is still under investigation. The aim of the study was to evaluate the expression of metalloproteinases 2 and 7 (MMP-2, -7) and tissue inhibitor of metalloproteinase 1 (TIMP-1) in human endometrium in relation to serum concentrations of estradiol and progesterone during different phases of menstrual cycle.Material and methods. The study material consisted of 52 biopsy samples; 12 obtained in the proliferative phase, 11 in the secretory phase and 29 during menstruation. Expression of MMP-2, MMP-7 and TIMP-1 was assessed by immunohistochemistry. Serum concentrations of estradiol and progesterone at time of biopsy were evaluated by immunochemistry assay. Results of the study were statistically assessed by linear regression model.Results. Increased serum concentration of estradiol was associated with increased MMP-2 expression in proliferative phase but decreased in secretory phase and during menstruation. No significant relationship was found between progesterone concentration and MMP-2 expression. Moreover, no difference in the expression of MMP-7 and TIMP-1 in the endometrium in relation to hormone levels and menstrual cycle phases were observed.Conclusions. The results of the study indicate that estradiol influence MMP-2 expression in the endometrium depends on the phase of menstrual cycle. Such relationships were not found for MMP-7 and TIMP-1 and further tests clarifying association between estradiol and MMPs are needed.

Postpregnancy glycemic control and weight changes in type 1 diabetic women

OBJECTIVE - Pregnancy in type 1 diabetes requires excellent glycemic control. Most pregnant type 1 diabetic women achieve normoglycemia; however, there is scarce data on their postdelivery characteristics. We aimed to examine postpregnancy glycemic control and weight changes in type 1 diabetes. RESEARCH DESIGN AND METHODS - We identified and followed (median 20 months) 254 women with singleton pregnancies receiving postdelivery medical care at a single institution. RESULTS - Study subjects were 28.3 6 4.7 years of age (mean 6 SD), with a diabetes duration of 12.0 6 7.7 years. Mean A1C before conception was 6.9 6 1.4%, and preconception weight and BMI were 64.4 6 10.0 kg and 23.9 6 3.3 kg/m2, respectively. Mean A1C decreased during pregnancy, reaching 5.7 6 0.8% in the third trimester. We observed a mean weight gain of 14.4 6 6.5 kg during pregnancy. Within 6 months after delivery, A1C increased by 0.8% (P , 0.0001) compared with the last trimester, and body weight and BMI were 4.4 kg and 2.5 kg/m2 higher (P , 0.0001) compared with the preconception baseline. A1C further deteriorated by 0.8% until the end of follow-up. For women in the "pregnancy planning" program (n = 117), A1C .12 months after delivery was worse compared with before conception (7.1 vs. 6.5%, P = 0.0018), whereas in women with unplanned pregnancies, it was similar to the pregestational levels (7.3 vs.7.4%, P = 0.59). Weight and BMI in the entire study group did not return to prepregnancy levels and were 2.5 kg (P = 0.0079) and 0.9 kg/m2 higher (P = 0.0058). CONCLUSIONS - In this clinical observation, type 1 diabetic women showed postpregnancy deterioration in glycemic control and were unable to return to prepregnancy weight. Type 1 diabetic women seem to require special attention after delivery to meet therapeutic targets

THE RELATION BETWEEN EMOTIONAL INTELLIGENCE AND INTERNET ADDICTION IN KATOWICE HIGH SCHOOL STUDENTS

Backgroud: Emotional intelligence (EI) is described as the capacity to be aware of, control, and express one\u27s emotions, and to handle interpersonal relationships judiciously and empathetically. It is considered as one of the most important predictors of success, quality of relationships, and overall happiness. Dynamically changing environment of the youth and young adults in recent years may influence their EI development, affecting their lives significantly. The purpose of this study was to analyse the way how the Internet is used by high school students, to determine the amount of time they spend on the Internet, identify the level of EI and to explore if there is any correlation between those factors. Subjects and methods: 1450 high school students from Katowice, at the age from 18 to 21 years took part in an anonymous survey consisting of three parts: The Trait Emotional Intelligence Questionnaire – Short Form (TEIQue-SF), Internet Addiction Test and authorial test giving information about the way of spending time online. The questionnaires were collected from May 2018 to January 2019. Results: 1.03% of the respondents fulfilled the Internet addiction criteria. Students at risk for addiction (33.5%) turned out to be a larger group. A statistically significant correlation between TEIQue-SF and Internet Addiction Test score (P<0.0001, r=-0.3308) was observed. Another significant correlation was found between TEIQue-SF score and amount of time spend on the Internet (p<0.0001, r=-0.162). Conclusion: A significant part of high school students used Internet excessively. Such behaviours were positively correlated with lower EI test results

Intrauterine growth restriction in pregnant women after kidney transplantation as a marker of preeclampsia

Objectives: Delayed motherhood is associated with an increasing number of comorbidities such as glomerulonephritis, systemic lupus erythematosus, and diabetic nephropathy. Women after renal transplant belong to the group of patients who require a highly individualized approach to treatment and diagnosis. The aim of the study was to validate the commonly used diagnostic criteria for preeclampsia which seem to be irrelevant in patients with chronic renal insufficiency.Material and methods: The course of pregnancy and delivery were retrospectively analyzed in 48 renal transplant patients. Two patients were excluded. Group I included 23 patients with eutrophic neonates, while Group II consisted of 23 patients with fetal hypotrophy (birth weight of &lt; 10th percentile).Results: The duration of pregnancy was 34.5 and 35 weeks in Groups I and II, respectively. Mean birth weight in Groups I and II was 2608.64 g and 2046.30 g, respectively (p = 0.002). Mean weight percentile in Groups I and II was 36.57 and 2.91, respectively (p &lt; 0.000). Proteinuria in the first half of pregnancy occurred in 16 and 14 patients from Groups I and II, respectively, and increased in the second half of pregnancy in 6 and 6 patients from Groups I and II, respectively. Patients from Group II were more prone to urinary tract infections (0.43 vs. 0.79; p = 0.02).Conclusions: Current diagnostic criteria for preeclampsia are insufficient in case of pregnant women after kidney transplant. General criteria should be applied with special care in women with chronic kidney disease or in patients with systemic lupus erythematosus. As a predictive factor of neonatal morbidity, intrauterine growth restriction seems to be more valuable than typical markers of kidney function

Complementary and alternative medicine in multiple sclerosis: a questionnaire-based study

Aim of the study. To assess the prevalence and characteristics of complementary and alternative medicine (CAM) use among multiple sclerosis (MS) patients in Poland. Clinical rationale for the study. Multiple sclerosis (MS) is a chronic, progressive and disabling neurological disease with significant impact on quality of life. Although the efficacy and safety of complementary and alternative medicine (CAM) has not been scientifically confirmed, many patients use CAM as a complement or an alternative to conventional therapy.Material and methods. Data was collected via a self-designed survey consisting of 33 questions. The questionnaire was distributed among MS patients hospitalised during 2016 in the MS Unit at the Department of Neurology, Medical University of Warsaw, Poland. The study group consisted of 75 patients (47 females, 28 males, mean age 44.6 ± 12.5 years) with clinically defined MS.Results. According to the questionnaire, 48 patients (64%) had used CAM at least once. Most of the patients declared that CAM had a possible (58%) or a marked (43.7%) positive effect. 61.4% of CAM users reported reduced fatigue and 33.3% improved mood. There were significant correlations between CAM use and lower social and professional status (p &lt; 0.04), disease progression (p &lt; 0.03), and lack of efficacy of disease-modifying therapies (p &lt; 0.04). There were no significant correlations between CAM usage and sex, habitation, education, marital or professional status. The most frequently used CAMs were vitamins (48%),and polyunsaturated fatty acids (36%); psychophysical methods (44%) included manual therapies (24%) and relaxation techniques (17.3%) as well as herbal medicine (29.3%). Physicians were considered to be the most reliable authority in both conventional treatment (97.3%) and CAM (67%). Complementary and alternative medicine users significantly more often discussed this issue with their doctors (56%) compared to patients who did not use alternative medicine (p &lt; 0.05). However, 54% of patients did not inform their physician about CAM use. Responders said that physicians did not initiate discussion about it (55.9%), but44% of patients would like to have the possibility of talking to a doctor about CAM.Conclusions and clinical implications. Although CAM efficacy and safety is not confirmed, one should keep in mind that most MS patients use alternative methods, especially those individuals with a more severe phenotype. Physicians are mostly perceived as reliable authorities and therefore they should discuss this issue with patients in order to eliminate drug interactions and to improve compliance
