Extreme Case of Surgical Port Metastasis in Ovarian Cancer.

Ovarian cancer accounts for more deaths than any other malignancy of the female reproductive system. Early diagnosis of this disease is difficult because there are no systematic opportunistic screening methods. At advanced stages, diagnostic laparoscopy is the first step in confirming disease advancement and obtaining samples for genetic and pathologic examination needed to start chemotherapy. Swiftly starting oncological treatment is crucial for increasing the survival rate in these patients. We present the case of a 51-year-old woman with metastatic International Federation of Gynecology and Obstetrics (FIGO) stage IIIC ovarian cancer who had delayed her therapy after initial laparoscopy due to COVID-19 infection and presented with an extreme case of surgical port metastasis.

The Comparison of Immunomodulatory Properties of Canine and Human Wharton Jelly-Derived Mesenchymal Stromal Cells.

Although therapies based on mesenchymal stromal cells (MSCs) are being implemented in clinical settings, many aspects regarding these procedures require further optimization. Domestic dogs suffer from numerous immune-mediated diseases similar to those found in humans. This study aimed to assess the immunomodulatory activity of canine (c) Wharton jelly (WJ)-derived MSCs and refer them to human (h) MSCs isolated from the same tissue. Canine MSC(WJ)s appeared to be more prone to in vitro aging than their human counterparts. Both canine and human MSC(WJ)s significantly inhibited the activation as well as proliferation of CD4+ and CD8+ T cells. The treatment with IFNγ significantly upregulated indoleamine-2,3-dioxygenase 1 (IDO1) synthesis in human and canine MSC(WJ)s, and the addition of poly(I:C), TLR3 ligand, synergized this effect in cells from both species. Unstimulated human and canine MSC(WJ)s released TGFß at the same level (p > 0.05). IFNγ significantly increased the secretion of TGFß in cells from both species (p < 0.05); however, this response was significantly stronger in human cells than in canine cells. Although the properties of canine and human MSC(WJ)s differ in detail, cells from both species inhibit the proliferation of activated T cells to a very similar degree and respond to pro-inflammatory stimulation by enhancing their anti-inflammatory activity. These results suggest that testing MSC transplantation in naturally occurring immune-mediated diseases in dogs may have high translational value for human clinical trials.

Soluble Forms of Immune Checkpoints and Their Ligands as Potential Biomarkers in the Diagnosis of Recurrent Pregnancy Loss-A Preliminary Study.

Immune checkpoints (ICPs) serve as regulatory switches on immune-competent cells. Soluble ICPs consist of fragments derived from ICP molecules typically located on cell membranes. Research has demonstrated that they perform similar functions to their membrane-bound counterparts but are directly present in the bloodstream. Effective control of the maternal immune system is vital for a successful pregnancy due to genetic differences between the mother and fetus. Abnormalities in the immune response are widely acknowledged as the primary cause of spontaneous abortions. In our research, we introduce a novel approach to understanding the immune-mediated mechanisms underlying recurrent miscarriages and explore new possibilities for diagnosing and preventing pregnancy loss. The female participants in the study were divided into three groups: RSA (recurrent spontaneous abortion), pregnant, and non-pregnant women. The analysis of soluble forms of immune checkpoints and their ligands in the serum of the study groups was conducted using the Luminex method Statistically significant differences in the concentrations of (ICPs) were observed between physiological pregnancies and the RSA group. Among patients with RSA, we noted reduced concentrations of sGalectin-9, sTIM-3, and sCD155, along with elevated concentrations of LAG-3, sCD80, and sCD86 ICPs, in comparison to physiological pregnancies. Our study indicates that sGalectin-9, TIM-3, sLAG-3, sCD80, sCD86, sVISTA, sNectin-2, and sCD155 could potentially serve as biological markers of a healthy, physiological pregnancy. These findings suggest that changes in the concentrations of soluble immune checkpoints may have the potential to act as markers for early pregnancy loss.

The Intersection of Human and Veterinary Medicine-A Possible Direction towards the Improvement of Cell Therapy Protocols in the Treatment of Perianal Fistulas.

The effective treatment of perianal fistulizing Crohn's disease is still a challenge. Local administration of mesenchymal stromal cells (MSCs) is becoming a part of accepted treatment options. However, as a fledgling technique, it still can be optimized. A new trend in translational research, which is in line with "One Health" approach, bases on exploiting parallels between naturally occurring diseases affecting humans and companion animals. Canine anal furunculosis (AF) has been indicated as condition analogous to human perianal Crohn's disease (pCD). This narrative review provides the first comprehensive comparative analysis of these two diseases based on the published data. The paper also outlines the molecular mechanisms of action of MSCs which are likely to have a role in modulating the perianal fistula niche in humans, and refers them to the current knowledge on the immunomodulatory properties of canine MSCs. Generally, the pathogenesis of both diseases shares main determinants such as the presence of genetic predispositions, dysregulation of immune response and the relation to intestine microbiota. However, we also identified many aspects which should be further specified, such as determining the frequency of true fistulas formation in AF patients, elucidating the role of TNF and Th17 pathway in the pathogenesis of AF, or clarifying the role of epithelial-to-mesenchymal transition phenomenon in the formation of canine fistulae. Nevertheless, the available data support the hypothesis that the results from testing cell therapies in dogs with anal furunculosis have a significant translational value in optimizing MSC transplants procedures in pCD patients.

Evaluation of the Optimal Manufacturing Protocols and Therapeutic Properties of Mesenchymal Stem/Stromal Cells Derived from Wharton's Jelly.

Wharton's jelly (WJ) from the umbilical cord (UC) is a good source of mesenchymal stem/stromal cells (MSCs), which can be isolated and used in therapy. Current knowledge shows that even small changes in the cell environment may result in obtaining a subpopulation of cells with different therapeutic properties. For this reason, the conditions of UC transportation, cell isolation, and cultivation and the banking of cells destined for clinical use should be unified and optimized. In this project, we tried various protocols for cell vs. bioptat isolation, banking, and transport in order to determine the most optimal. The most efficient isolation method of WJ-MSCs was chopping the whole umbilical matrix with a scalpel after vessel and lining membrane removal. The optimal solution for short term cell transportation was a multi-electrolyte fluid without glucose. Considering the use of WJ-MSCs in cell therapies, it was important to investigate the soluble secretome of both WJ bioptats and WJ-MSCs. WJ-MSCs secreted higher levels of cytokines and chemokines than WJ bioptats. WJ-MSCs secreted HGF, CCL2, ICAM-1, BDNF, and VEGF. Since these cells might be used in treating neurodegenerative disorders, we investigated the impact of cerebrospinal fluid (CSF) on WJ-MSCs' features. In the presence of CSF, the cells expressed consecutive neural markers both at the protein and gene level: nestin, ß-III-tubulin, S-100-ß, GFAP, and doublecortin. Based on the obtained results, a protocol for manufacturing an advanced-therapy medicinal product was composed.

Video-Based Microsurgical Education versus Stationary Basic Microsurgical Course: A Noninferiority Randomized Controlled Study.

BACKGROUND: Repetitive training is essential for microsurgical performance. This study aimed to compare the improvement in basic microsurgical skills using two learning methods: stationary microsurgical course with tutor supervision and self-learning based on digital instructional materials. We hypothesized that video-based training provides noninferior improvement in basic microsurgical skills. METHODS: In this prospective study, 80 participants with no prior microsurgical experience were randomly divided into two groups: the control group, trained under the supervision of a microsurgical tutor, and the intervention group, where knowledge was based on commonly available online instructional videos without tutor supervision. Three blinded expert microsurgeons evaluated the improvement in basic microsurgical skills in both groups. The evaluation included an end-to-end anastomosis test using the Ten-Point Microsurgical Anastomosis Rating Scale (MARS10) and a six-stitch test on a latex glove. Statistically significant differences between groups were identified using standard noninferiority analysis, chi-square, and t-tests. RESULTS: Seventy-seven participants completed the course. Baseline test scores did not differ significantly between groups. After the 4-day microsurgical course, both groups showed statistically significant improvement in microsurgical skills measured using the MARS10. The performed tests showed that data for self-learning using digital resources provides noninferior data for course with surpervision on the initial stage of microsurgical training (7.84; standard deviation [SD], 1.92; 95% confidence interval [CI], 7.25-8.44) to (7.72; SD, 2.09; 95% CI, 7.07-8.36). CONCLUSION: Video-based microsurgical training on its initial step provides noninferior improvement in microsurgical skills to training with a dedicated instructor.

Peritoneal Fluid from Patients with Ovarian Endometriosis Displays Immunosuppressive Potential and Stimulates Th2 Response.

Endometriosis is a common gynaecological disorder characterized by the ectopic growth of endometrial tissue outside the uterine cavity. It is associated with chronic pelvic inflammation and autoimmune reactivity manifesting by autoantibody production and abrogated cellular immune responses. Endometriotic peritoneal fluid contains various infiltrating leucocyte populations and a bulk of proinflammatory and immunoregulatory cytokines. However, the nature and significance of the peritoneal milieu in women with endometriosis still remains obscure. Therefore, the aim of the present study was to investigate the immunoregulatory activity of the peritoneal fluid (PF) from women with endometriosis. The peritoneal fluid samples were collected during laparoscopic surgery from 30 women with and without endometriosis. Immunoregulatory cytokines (IL-2, IL-4, IL-6, IL-10, IL-17A, IFN-γ and TNF) and chemokines (CCL2, CCL5, CXCL8 and CXCL9) were evaluated in PF and culture supernatants generated by unstimulated and CD3/CD28/IL-2-stimulated CD4+ T cells cultured in the presence of PF. The effect of PF on the generation of Treg and Th17 cells in CD4+ T cell cultures, as well as the natural cytotoxic activity of peripheral blood mononuclear cells, was also investigated. Concentrations of IL-6, IL-10, CCL2, CXCL8 and CXCL9 were significantly upregulated in the PF from women with endometriosis when compared to control women, whereas concentrations of other cytokines and chemokines were unaffected. The culturing of unstimulated and CD3/CD28/IL-2-stimulated CD4+ T cells in the presence of endometriotic PF resulted in the downregulation of their IL-2, IFN-γ, IL-17A and TNF production as compared to culture medium alone. On the other side, endometriotic PF significantly stimulated the production of IL-4 and IL-10. Endometriotic PF also stimulated the release of CCL2 and CXCL8, whereas the production of CCL5 and CXCL9 was downregulated. Endometriotic PF stimulated the generation of Treg cells and had an inhibitory effect on the generation of Th17 cells in cultures of CD4+ T cells. It also inhibited the NK cell cytotoxic activity of the peripheral blood lymphocytes. These results strongly imply that the PF from patients with endometriosis has immunoregulatory/immunosuppressive activity and shifts the Th1/Th2 cytokine balance toward the Th2 response, which may account for deviation of local and systemic immune responses. However, a similar trend, albeit not a statistically significant one, was also observed in case of PF from women without endometriosis, thus suggesting that peritoneal milieu may in general display some immunoregulatory/immunosuppressive properties. It should be stressed, however, that our present observations were made on a relatively small number of PF samples and further studies are needed to reveal possible mechanism(s) responsible for this phenomenon.

Expression of matrix metalloproteinase enzymes in endometrium of women with abnormal uterine bleeding.

OBJECTIVES: Abnormal uterine bleeding (AUB) is caused by derangement of physiological processes of tissue growth, shedding and regeneration. It is known that interplay between metalloproteinases (MMP's) and tissue inhibitors of metalloproteinases (TIMP's) may play a crucial role in its occurrence. AIM: To define if expression of proMMP-2, MMP-2 and TIMP-1 in endometrium of women with AUB is dependent on steroid sex hormone concentration and histopathological picture. MATERIALS AND METHODS: Endometrial scraps were taken from 21 women with AUB and 19 controls. Samples were evaluated in light microscopy by a certified pathologist. Activity of proMMP-2 and MMP-2 proteins levels were evaluated by gelatin zymography and TIMP-1 by reversed zymography. The results has been correlated with serum estradiol and progesterone concentrations in linear regression model. RESULTS: Expression: of proMMP-2 in endometrium of women with AUB is correlated with estradiol concentration and inversely correlated with progesterone levels. It was significantly higher in women with dysfunctional endometrium (p<0.001). Expression of MMP-2 was highest in women with endometrial polyps and longer bleeding (p<0.01), while expression of TIMP-1 was independent from hormone concentration. CONCLUSION: Lack of correlation between proMMP-2 and MMP-2 levels suggest different pathway of their activation in AUB. ProMMP-2 is up regulated by estradiol and down regulated by progesterone while MMP-2 levels increase with the length of bleeding.

Dietary vitamin and mineral intakes in a sample of pregnant women with either gestational diabetes or type 1 diabetes mellitus, assessed in comparison with Polish nutritional guidelines.

OBJECTIVES: Maintaining proper nutrition during pregnancy is crucial for pregnant women and especially for who have been diagnosed with type 1 diabetes mellitus (T1DM) or who develop gestational diabetes mellitus (GDM). MATERIAL AND METHODS: To measure differences in vitamin and mineral intakes among women with normal pregnancies, pregnant women with GDM, and pregnant women with pre-gestational T1DM; and to assess the women's dietary intakes in comparison with Polish nutritional guidelines. The analysis was conducted among 83 pregnant women (29 GDM patients, 26 T1DM patients and 28 normal pregnancy participants) from whom we collected seven-day 24-hour dietary records during the second part of their pregnancies. RESULTS: There were no statistically significant differences observed for most of the vitamin and mineral intakes across the three groups. However, we did observe a significant difference in the vitamin C and calcium intakes between groups. The mean vitamin C and calcium intakes were significantly higher in the control group than among the diabetic patients. Insufficient dietary calcium intakes were found among 52.3% of the GDM patients and 61.6% of the T1DM participants, while only 28.6% of the normal pregnancy patients experienced a calcium deficiency. The highest incidence of inadequate intake in each of the GDM, T1DM and control groups was observed for vitamin D (100%, 100%, 100%), folate (97.7%, 100%, 100%), iron (97.7%, 100%, 100%), and iodine (97.7%, 92.4%, 85.7%), respectively. CONCLUSIONS: Diet alone may not be enough to provide adequate levels of vitamins and minerals for most micronutrients. Supplement use reduces the risk of inadequate intake for many micronutrients, but diet-related issues during pregnancy and pregnancy diagnosed with diabetes remain, and they deserve to be addressed during public health interventions.

Dietary macronutrients and fluid intakes in a sample of pregnant women with either gestational diabetes or type 1 diabetes mellitus, assessed in comparison with Polish nutritional guidelines.

OBJECTIVES: Pregnancy is a critical period during which environmental factors such as nutrition can affect development. Maintaining proper nutrition becomes even more significant when pregnant women have diabetes. The aim of this study was to measure changes in energy and macronutrient intakes among pregnant women and patients diagnosed either with gestational diabetes mellitus (GDM) during pregnancy, or, type 1 diabetes mellitus (T1DM) before pregnancy, and to assess the pregnant women's dietary intakes in comparison with Polish Institute of Food and Nutrition nutritional guidelines. MATERIAL AND METHODS: The analysis was conducted among 83 pregnant women (29 GDM patients, 26 T1DM patients and 28 normal pregnancy patients - the control group) from whom we gathered nutritional data during the second part of their pregnancies. Data on each woman's diet during pregnancy was collected is self-completed dietary records during seven consecutive 24-hour periods. RESULTS: The mean macronutrient intake of the GDM patients was 32.1% fat, 19.5% protein, and 48.3% carbohydrates; in the T1DM group the results were 34.2%, 19.4% and 46.4% respectively; and in control group they were 31.8%, 17.6% and 50.5% respectively. This study showed that many of the pregnant women did not reach the recommended level of energy intake during pregnancy. Moreover, most of the women exceeded their fat requirements, and fat intake as a proportion of energy intakes also exceeded the guidelines in more than 60% of the women across all groups. CONCLUSIONS: The implications and possible causes of excessive fat intake during pregnancy and pregnancies complicated by diabetes are underestimated and undertreated by obstetricians and warrant further investigation, especially in association with gestational weight gain, maternal and fetal perinatal complications, and post-gestational diabetes.

Mesenchymal Stem Cells from Human Amniotic Membrane and Umbilical Cord Can Diminish Immunological Response in an in vitro Allograft Model.

BACKGROUND/AIM: Mesenchymal stem cells (MSCs) are gaining rising interest in gynecology and obstetrics. MSCs immunomodulatory properties are suitable enough to reduce perinatal morbidity caused by inflammation in premature neonates. The aim of this study was to evaluate and compare the ability to inhibit allo-activated lymphocytes proliferation by MSCs derived from different sources: amniotic membrane (AM), umbilical cord (UC) and adipose tissue (AT). METHODS: MSCs were isolated from AM (n = 7) and UC (n = 6) and AT (n = 6) of healthy women. Cells were characterized by flow cytometry and differentiation assay. To evaluate the potential of fetal and adult MSCs to diminish immunological response, mixed lymphocytes reaction (MLR) was performed. RESULTS: Amnion and UC-derived cells displayed typical MSCs characteristics. Addition of MSCs to MLR significantly inhibited the proliferation of stimulated lymphocytes. The effect was observed regardless of the MSCs type used (p < 0.01 in all groups). Comparative analysis revealed no significant differences in this action between tested MSCs types. Additionally, no type of MSCs significantly stimulated allogeneic lymphocytes. CONCLUSION: The results prove the immunosuppressive capacities of fetal-derived MSCs in vitro. In the future, they may be potentially used to treat premature newborn as well as in immunomodulation in post-transplant therapy.

Comparison of the paracrine activity of mesenchymal stem cells derived from human umbilical cord, amniotic membrane and adipose tissue.

AIM: The study was conducted to investigate secretory activity and define the paracrine potential of mesenchymal stem cells from human umbilical cord and amniotic membrane (UC-MSCs and AM-MSCs, respectively). METHODS: UC-MSCs (n = 6) were obtained from tissue explants using an adherent method after two weeks of incubation. AM-MSCs (n = 6) were obtained by digestion with tripsin and collagenase. MSC phenotype was confirmed in vitro by performing flow cytometry, differentiation assays and vimentin staining. Supernatants were collected after 48 h culturing in serum-free conditions and the following concentrations were determined: epidermal growth factor (EGF), interleukin (IL)-6, IL-10, tumor necrosis factor-α, transforming growth factor-ß (TGF-ß), vascular endothelial growth factor-α (VEGF-α) and metalloproteinase (MMP) 1, 8 and 13, using multiplex supernatant cytokine assay. Data were compared with adipose tissue derived MSCs (AD-MSCs, n = 6). RESULTS: Both UC-MSC and AM-MSC populations were positively identified as MSCs by flow cytometry and differentiation potential into bone, cartilage and adipose tissue. Using a multiple cytokine detection assay, we proved that both UC-MSCs and AM-MSCs show high secretive capacity. However, the secretion profile differed between cells from various sources. UC-MSCs showed significantly higher production of TGF-ß and lower production of VEGF-α, compared to AD-MSCs (P = 0.004) and AM-MSCs (P = 0.039) and lower levels of EGF (P = 0005). AM-MSCs showed significantly lower levels of MMP-8 than UC-MSCs (P = 0.024); however, there was no difference in levels of released cytokines compared to AD-MSCs. CONCLUSION: AM-MSCs show similar IL production as AD-MSCs, while UC-MSCs have a significantly different profile, which suggests diverse biological potential of both cell types for immunomodulative and regenerative therapy.

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.

Premature fetal tissues are possible source of valuable mesenchymal stem cells.

OBJECTIVES: Comparison of the ability to inhibit alloactivated lymphocytes proliferation of human Wharton Jelly (WJ) and amniotic membrane (AM) mesenchymal stem cells (MSCs) from preterm and term pregnancies. MATERIAL AND METHODS: Term-WJ-MSCs (n = 5) and Preterm-WJ-MSCs (n = 1) were obtained from tissue explants by adherent method. Term-AM-MSCs (n = 5) and Preterm-AM-MSCs (n = 1) were obtained by tripsin and collagenase digestion method. Term and Preterm MSCs phenotype was confirmed in vitro by flow cytometry. To evaluate the potential of fetal and adult MSCs to diminish immunological response mixed lymphocytes reaction (MLR) has been performed. RESULTS: Term and Preterm cells were positively identified as MSCs by the expression of CD73 and CD90 and CD105 with simultaneous absence of CD11b, CD14, CD19, CD34, CD45 and HLA-DR. The mean inhibition of allostimulated lymphocytes after addition of fetal derived MSCs amounted 64.8% for term AM-MSCs and 42.1% for term WJ-MSCs (for both populations the effect was statistically significant, p < 0.01). The addition of preterm-MSCs to MLR resulted in reduction of stimulated lymphocytes proliferation by 64.9% for AM-MSCs and 86.1% for WJ-MSCs. CONCLUSIONS: Presented results suggest that preterm fetal tissues contain MSCs which posses similar immunosuppressive capacity as those from term pregnancies. In the future MSCs from the umbilical cord and amnion can be potentially used to prevent immuno-dependent injuries in premature newborns.

[Attitudes of polish physicians towards extending competencies of nurses and midwives with respect to prescribing medicines].

INTRODUCTION: Due to the amendment of the Nurse and Midwife professions Act, since 1st of January 2016 Polish nurses and midwives with certain qualifications are able to prescribe medicines and referral for diagnostic tests. THE AIM: To analyse attitudes of physicians on new professional competencies of nurses and midwives regarding: prescribing medicines and referring patients for certain diagnostic tests. MATERIAL AND METHODS: In the study took part 436 physicians (245 women, 193 man). The average age was 36,6 years old (min.: 21; max.: 76; SD: 11,65; median: 31). 274 people lived in a city with over 500 thousand citizens, 70 people - city below 100 thousand citizens, 54 people - city between 100-500 thousands citizens and 14 people lived in a country. Most of people lived in masovian district. Authors prepared and validated own questionnaire, which contained statements assessed in Likert scale (1-strongly disagree, 5-stronlgy agree). It contained 22 questions about opinions of new abilities of nurses and midwives. The questionnaire was sent three times to Regional Medical Chamber in Warsaw via an online questionnaire: https://docs.google.com/forms/d/1cxiaJFPxDVphByhBTk4gDIBsm6bQsxGLVXDK-RtpGnk/ The reliability of the questionnaire used was tested in a pilot study by the coefficient α-Cronbach, which amounted to 0.937. Due to the fact that the study was performed in a group of doctors they did not require the consent of the Bioethics Committee, of Medical University of Warsaw to carry them out. The results are presented using descriptive statistics, which were obtained through statistical analysis using Microsoft Excel and StatSoft Statistica 12.0 (license Medical University of Warsaw). RESULTS: 53% of doctors claim that the new powers do not improve patient care. 35% of respondents disagreed with the opinion that the new powers will raise the prestige of professional nurses and midwives. At the same time 49% believe that prescriptions for nurses and midwives reduce the responsibilities of doctors. Only 9% agreed that the new abilities are needed in Poland. 65% of doctors have expressed the opinion that nurses and midwives should not have permission to prescriptions and 81% believe that they are not prepared for those abilities. CONCLUSION: Doctors have divided opinion about the benefits of the introduction of the nursing prescriptions for the patient. It is therefore, considered an information campaign through the mass media, or training in the workplace, where they will be presented in an objective manner the consequences of the introduction of new regulations.

Pregnancy in the liver transplant recipient.

During gestation, the woman's body undergoes various changes, and the line between physiology and pathology is very thin even in healthy women. Today, many of the liver transplant recipients are young women, who at one point in their lives may consider the possibility of pregnancy. Clinicians have to counsel them about the time of conception, the risk of miscarriage, the deterioration of the mother's health status, and the risk of birth defects. This review, based on our 20 years of clinical experience and up-to-date literature, provides comprehensive guidelines on pregnancy management in liver transplant recipients. Pregnancy in liver transplant recipients is possible but never physiological. Proper management and pharmacotherapy lowers the incidence of complications and birth defects. Critical factors for perinatal success include stable graft function before pregnancy, proper preparation for pregnancy, and cautious observation during its course.

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 < 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 < 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.

First and third trimester serum concentrations of adropin and copeptin in gestational diabetes mellitus and normal pregnancy.

OBJECTIVES: Gestational diabetes mellitus (GDM) is a metabolic disease diagnosed in 1.7% up to 11.6% pregnancies. The prevalence of adverse pregnancy outcome is significantly higher in the case of early onset of diabetes mellitus. Adropin is a hormone promoting carbohydrate oxidation over fat oxidation, and influence nitric oxide synthase. Copeptin is a cleavage product of the vasopressin precursor recently correlated with diabetes mellitus. The aim of the study was to determine maternal serum adropin and copeptin concentrations in women with early and late manifestation of GDM and to discuss their potential role as biochemical markers of insulin resistance. MATERIAL AND METHODS: Case-control study on 58 pregnant Caucasian women. Serum levels of adropin and copeptin were assessed in patients with early onset (GDM1) and classical gestational diabetes mellitus (GDM2). Complications such as macrosomia and hypotrophy were evaluated. RESULTS: There was no significant difference between the study and the control group (age, BMI, parity). Fetal growth disturbance rate was 37.5% in GDM1, 11% in GDM2 and 6% in controls. Adropin concentration in GDM patients was significantly higher than in control group (p < 0.001), but there was no difference between GDM1 and GDM2 group. High serum concentration of adropin positively correlated with elevated HbA1c (p < 0.05). The groups did not differ in terms of copeptin serum concentration. CONCLUSIONS: High adropin serum concentration in GDM patients is associated with increased risk of fetal growth disturbances, possibly due to improper placentation. According to our prospective study, neither copeptin nor adropin serum concentration are useful to discriminate between early and late onset of gestational diabetes mellitus.

Non trophoblastic source of human chorionic gonadotropin - problem in diagnostic accuracy.

Human chorionic gonadotropin (hCG) is a polypeptide hormone studied as far as 1912, but researchers has no complete knowledge concerning its biological function. Since 1970' it is known that hCG can be found not only in the urine and serum of pregnant, but in choriocarcinoma and testicular cancer patients. Up-to-date one can distinguish four subtypes of hCG differing in secondary carbohydrate chains configuration as well as it regular and glycosylated forms, but non trophoblastic sources of this hormone, such as pituitary are still not widely known. The article gives an overlook on hCG studies in order to help clinicians in taking wise, evidence based decisions in asymptomatic patients with elevated hCG.

Bilateral fatigue fractures of the bones of both crura in a patient with a history of abuse of alcohol and psychoactive substances treated with Ilizarov external fixator apparatus.

BACKGROUND: Fatigue (slow) fractures are a result of cyclic burden on the affected bones. At the same time, regeneration processes are disturbed or appropriate mechanical environment to promote healing is lacking. Fatigue fractures are classified into two types: stress fractures and deficiency fractures. The former occur as a result of excessive training in healthy individuals with normal bone structure, e.g. in sportsmen and soldiers. Deficiency-related fractures are most common in individuals with metabolic disorders that affect bone mineralization, such as osteomalacia or osteoporosis. CASE REPORT: The article presents a case of a 37-year-old male with fatigue fractures within both crura. During the interview, the patient reported the abuse of alcohol and benzodiazepines and the history of using other psychoactive substances. CONCLUSIONS: Fractures were treated using Ilizarov external fixator apparatus. Bone union was achieved after several months of external fixation.
