RESUMO

Galectins are known to play an important role in immunoregulatory processes and autoimmune diseases. Galectin-10 is a cytoplasmic protein of human eosinophils and is involved in various eosinophilic diseases. Since increased galectin expression is already detected in the placentas of mothers with gestational diabetes mellitus (GDM), this study focuses on the specific role of galectin-10 and hints at consequences for the diagnosis and therapeutic options of GDM. It is hypothesized that the difference in galectin-10 expression will raise the pathophysiological understanding of gestational diabetes. The study population consists of 80 women: 40 healthy mothers and 40 women suffering from gestational diabetes mellitus. The expression of galectin-10 was analyzed in the syncytiotrophoblast (SCT) and the decidua of the placenta via immunohistochemistry and immunofluorescence double staining. The immunoreactivity score (IRS) was used for evaluation. The results in this study were significant for an overexpression of galectin-10 in GDM placentas compared with the control group. The syncytiotrophoblast showed overexpression in the nucleus and the cytoplasm, whereas expression of galectin-10 in the decidua was significant in the cytoplasm only. This study identified the expression changes in galectin-10 in placental tissue between healthy and GDM mothers and intensified the understanding of gestational diabetes. Assuming that gestational diabetes mellitus is involved in inflammatory processes, galectin-10 might play a role in the development and maintenance of GDM. Further investigation is required to strengthen these findings.

RESUMO

Vulvar cancer incidence numbers have been steadily rising over the past decades. In particular, the number of young patients with vulvar cancer has recently increased. Therefore, the need to identify new prognostic factors and, in addition, therapeutic options for vulvar carcinoma is more apparent. The aim of this study was to analyze the influx of COX-2 positive tumor-infiltrating lymphocytes and monocytes and their influence on prognosis. Using subtyping by immunofluorescence, the majority of COX-2 expressing immune cells were identified as FOXP3-positive regulatory T cells. In addition, peri- and intra-tumoral macrophages in the same tumor tissue were detected simultaneously as M2-polarized macrophages. COX-2 positive immune cells were independent negative prognostic markers in long-term overall survival of patients with vulvar cancer. These results show an influence of immune cell infiltration for vulvar carcinoma patients. Immune cell infiltration and immune checkpoint expression may, therefore, become interesting targets for further research on new vulvar cancer treatment strategies.

RESUMO

PURPOSE: The aim of this study was to evaluate the effect of a pilot interdisciplinary inhouse training in palliative care (PC) for gynecological oncologists. METHODS: Competencies of participants from a gynecological university department were evaluated taking part in an interdisciplinary PC course in a pre and post design. The multiprofessional course covered basic principles of PC, symptom management and communication taught by PC specialists. Competencies were evaluated using self-designed questionnaires before (ISPG-1), right after (ISPG-2), and 6 months after the training (ISPG-3) (inhouse seminar palliative care in gynecology: ISPG). RESULTS: 31 persons from the department of gynecology took part in the course, of which 27 answered the first questionnaire (seven nurses (26%), 19 doctors (71%), one profession not indicated (3%), median working experience in gynecological oncology: 5 years). Return rates were: ISPG-1 27/31 (87.1%), ISPG-2 20/31 (64.5%) and IPSG-3 14/31 (45.2%). A more positive attitude towards PC could be observed in the majority of participants after the course (ISPG-2 62%, ISPG-3 71%). They felt more competent in the care of palliative patients (46%). PC would be initiated earlier and the interaction with other disciplines was improved (ISPG-2 85%, ISPG-3 100%). The participants assessed a significant improvement of their skills in all palliative fields which were analyzed. CONCLUSION: PC inhouse training improves the understanding of PC and the interdisciplinary approach in the management of patients with advanced disease. It is a feasible and useful instrument to improve the competencies in generalist PC of specialists in gynecological oncology.

RESUMO

BACKGROUND: We investigated whether obese pregnant women negative for gestational diabetes (GDM) still experience dysglycemia, as indicated by high glycated hemoglobin (Hb A1c) at delivery, and whether this impacts offspring and long-term maternal outcomes. METHODS: Data of 462 mother-child pairs of our prospective Programming of Enhanced Adiposity Risk in Childhood - Early Screening (PEACHES) cohort study were analyzed. Of 885 obese and normal-weight pregnancies prospectively enrolled after GDM testing according to the International Association of Diabetes and Pregnancy Study Groups criteria, 462 GDM-negative mothers and their offspring were investigated. We assessed associations of maternal Hb A1c at delivery with large-for-gestational-age (LGA) birth weights, cord-blood C-peptide, and biomarkers of glucose metabolism and inflammation in obese mothers followed for 2.9 years (median) postpartum (n = 42). RESULTS: Cumulative distribution analysis in GDM-negative normal-weight women (n = 155) revealed that 12% had Hb A1c ≥5.7% at delivery (high Hb A1c). Among obese GDM-negative women (n = 307), 31.9% (95% CI, 26.7%-37.4%) equaled or exceeded this cutoff. In obese GDM-negative women with Hb A1c ≥5.7% (n = 98) vs <5.7% (n = 209) at delivery, newborns were more likely to be born LGA [adjusted odds ratio 3.56 (95% CI, 1.64-8.02)], and mean cordblood serum C-peptide was increased by 0.09 ng/mL (95% CI, 0.01-0.17 ng/mL). In the mothers at follow-up, mean postpartum Hb A1c, fasting glucose, high-sensitivity C-reactive protein, and fibrinogen concentrations were higher by 0.3% (95% CI, 0.1%-0.5%), 6.0 mg/dL (95% CI, 2.4-9.5 mg/dL), 6.8 mg/L (95% CI, 1.4-12.3 mg/L), and 74.9 mg/dL (95% CI, 13.6-136.2 mg/dL), respectively. CONCLUSIONS: Increased Hb A1c in obese GDM-negative women at delivery indicates gestational dysglycemia, potentially conferring offspring and long-term maternal health risks. These findings should raise awareness as to careful monitoring of obese pregnancies. Measurement of Hb A1c at delivery could help select women who may need closer postpartum health checks.

RESUMO

INTRODUCTION AND HYPOTHESIS: Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) is a rare genital aplasia syndrome. Patients with MRKH regularly dilate their neovagina with vaginal dilatators. METHODS: A 23-year-old MRKH syndrome patient came to our department complaining of a lost vaginal dilator, which she had inserted 2 days previously. She had no bleeding or abdominal pain, but did have occasional urine loss. She had a history of abdominal exploration for an acute abdomen and the creation of a neovagina at the age of 16. An abdominal CT scan located the dislocated dilator intravesically. After diagnostic laparoscopy, the dilator was removed through the vesico-neovaginal perforation. The vagina was closed and covered by a pedicled peritoneal flap, followed by closure of the urinary bladder. An omental J-flap was then fixed between the vagina and bladder. RESULTS: The operative time was 185 min, with no significant blood loss, injuries or need for conversion/revision. The indwelling catheter was removed 7 days later after cystography, followed by normal micturition and an adequate bladder capacity. Vaginal dilation and sexual activity was resumed 1 month postoperatively. Follow-up was uneventful. CONCLUSIONS: Laparoscopic vaginal dilator removal with immediate repair of the perforation of the neovagina and the urinary bladder directly after an acute trauma in a patient with MRKH syndrome may be a management option. It is a feasible, safe and viable operation in the hands of experienced laparoscopists.

RESUMO

OBJECTIVES: Gestational diabetes mellitus (GDM) is a growing health concern. Since members of the galectin-family are identified to play a role in the pathogenesis of GDM, we determined galectin-12 as an essential protein due to its influence in lipolysis and inflammation processes. This study investigates the expression of galectin-12 in the placentas of women with GDM. STUDY DESIGN: The study population includes 40 expectant women suffering from GDM and 40 healthy controls. The expression of galectin-12 in the syncytiotrophoblast (SCT) and the extra villous trophoblast (EVT) of the placenta was analyzed by immunohistological staining and double immunofluorescence. Immunoreactivity Score (IRS) was used for evaluation. RESULTS: The results demonstrate a significant overexpression of galectin-12 in the nucleus of the SCT and the EVT of placentas with GDM compared to the healthy control group. Additionally, double immunofluorescence visualizes corresponding results with an overexpression of galectin-12 in the extra villous trophoblast of GDM placentas representing maternal cells. CONCLUSION: This study identifies galectin-12 to be associated with the process of gestational diabetes mellitus. These findings are in correspondence with the involvement of galectin-12 in inflammatory processes. Maternal BMI and male sex seem to be confounder for the expression of galectin-12 in the nuclear syncytiotrophoblast, but not in other parts of the investigated placental areas. Further investigations are necessary to verify the correlation between gestational diabetes mellitus and the expression of galectin-12 in the placenta and to further elucidate its distinct role.

RESUMO

OBJECTIVE: Hypertensive disorders during pregnancy remain a major health burden. Normal pregnancy is associated with systemic cardiovascular adaptation. The augmentation index and pulse wave velocity measures may serve as surrogate markers of cardiovascular pathology, including pre-eclampsia. We evaluated these parameters during and after normotensive and pre-eclamptic pregnancies. DESIGN: Longitudinal cohort trial involving a case-control analysis of healthy women and women with pre-eclampsia. SETTING: University hospital. POPULATION: Fifty-three healthy pregnant women between 11(+6) and 13(+6) gestational weeks, as well as 21 patients with pre-eclampsia. METHODS: The augmentation index and pulse wave velocity were measured seven times during pregnancy and postpartum. MAIN OUTCOME MEASURES: Changes in augmentation index and pulse wave velocity during and after healthy pregnancies were measured. The influence of early-onset and late-onset pre-eclampsia on these measurements both during and after pregnancy was evaluated. RESULTS: The normotensive pregnancies exhibited a significant decrease in the augmentation index from the first trimester to the end of the second trimester; however, the normotensive pregnancies showed an increase in the augmentation index during the third trimester as term approached. The patients with early-onset and late-onset pre-eclampsia displayed a significantly elevated augmentation index during pregnancy. The postpartum augmentation index and pulse wave velocity were significantly elevated in the early-onset pre-eclampsia group. CONCLUSION: After pregnancy, early-onset and late-onset pre-eclamptic patients exhibit differences in vascular function. This result indicates the presence of a higher cardiovascular risk in patients after early-onset pre-eclampsia.

RESUMO

Vulvar cancer incidence numbers have been rising steadily over the past decades. Especially the number of young patients with vulvar cancer increased recently. Therefore, the need to identify new prognostic factors for vulvar carcinoma is more apparent. Cyclooxygenase-2 (COX-2) has long been an object of scientific interest in the context of carcinogenesis. This enzyme is involved in prostaglandin synthesis and the latter binds to nuclear receptors like PPARγ. Therefore, the aim of this study was to investigate COX-2- and PPARγ- expression in tissues of vulvar carcinomas and to analyze their relevance as prognostic factors. The cytoplasmatic expression of COX-2 as well as PPARγ is associated with a significantly reduced survival, whereas nuclear expression of PPARγ results in a better survival. Especially the combined expression of both COX-2 and PPARγ in the cytoplasm is an independent negative prognosticator for vulvar cancer patients.

RESUMO

BACKGROUND: This study evaluates interventions offered to young breast cancer (BC) patients, including fertility preservation, genetic testing, and counseling for parenthood concerns, and analyzes the effect of BC on biographical issues. METHODS: Women who were diagnosed with BC at the age of 18-40 years and who underwent treatment at the Breast Center, Ludwig-Maximilian University (LMU) in Munich between 2006 and 2013, were eligible for this study. Patients received a self-developed questionnaire which covered the following topics: fertility preservation, family planning, genetic testing, parenthood concerns and children's needs, partnership status, and employment situation. RESULTS: Re-evaluating their initial decision on fertility preservation, 76.4% of patients reported satisfaction with their decision. After BC diagnosis, 45.8% reported to have maternal desire, but only 21.7% actually planned to have children. 41.7% of patients missed sufficient counseling regarding parenthood concerns. Analysis of individual employment situations showed that the time period until the return to work was longer in patients who received chemotherapy. The majority of patients (71.6%) did not report changes in their partnership status. CONCLUSION: Young BC survivors report a lack of communication related to parenthood concerns and future conception, but are satisfied with counseling regarding fertility preservation and genetics.
