Abstract Background: Brain-derived neurotrophic factor (BDNF) has been recognized as a regulator in the formation and maintenance of chronic pain in various chronic disorders. BDNF together with its high-affinity tyrosine kinase type B (TrkB) receptor were found to be extensively expressed in mammalian female reproductive system. However, BDNF and TrkB expression in different stages of endometriosis, and the correlation between their expression in ectopic lesions and endometriosis pain remains unclear.Methods: This study enrolled sixty-two women underwent laparoscopic surgery. Forty-six women diagnosed as ovarian endometrioma, were recruited in the study group. Sixteen women diagnosed as ovarian benign tumors were recruited in the control group. Samples from eutopic endometrium and ovarian endometriotic lesions were obtained at laparoscopic surgery. The message RNA (mRNA) level of BDNF and TrKB was detected by real-time PCR, while the protein level was detected by immunohistochemical staining for eutopic and ectopic endometrium in both groups. Dysmenorrhea was assessed by the visual analogue scale (VAS) before the surgery.Results: The expression of BDNF and TrKB were higher in ovarian endometriotic lesions than those in eutopic endometrium and normal endometrium (P<0.05), and there was no cyclical change. While their expression in eutopic endometrium were higher than those in the normal endometrium (P<0.05). The expression of BDNF and TrKB in ovarian endometriotic lesions stage IV were higher than those in stage III and II (P<0.05). Their expression in stage III were higher than those in stage II but there were no significance (P>0.05). Furthermore, the correlation between the mRNA expression of BDNF, TrKB in eutopic endometrium, and dysmenorrhea VAS score revealed that r=0.52 and 0.56, respectively (P<0.05). The correlation between BDNF and TrKB in both eutopic and ectopic endometrium were revealed that r=0.82 and 0.66, respectively (P<0.05).Conclusions: BDNF and TrKB may play essential roles in promoting disease progression during the development of endometriosis, and are closely related to dysmenorrhea caused by endometriosis.

However, BDNF and TrkB expression in different stages of endometriosis, and the correlation between their expression in ectopic lesions and endometriosis pain remains unclear.Methods: This study enrolled 78 women underwent laparoscopic surgery. 62 women diagnosed as ovarian endometrioma, were recruited in the study group.16 women diagnosed as ovarian benign tumors were in the control group. The message RNA (mRNA) level of BDNF and TrKB was detected by real-time PCR, while the protein level was detected by immunohistochemical staining for eutopic and ectopic endometrium in both groups. Dysmenorrhea was assessed by the visual analogue scale (VAS) before the surgery.Results: Immunohistochemical analysis revealed that the expression of BDNF and TrKB in ovarian endometriotic lesions was the highest, followed by those in eutopic and normal endometrium (P<0.05). There was significant difference among each stage of endometriosis for the expression, which increased with the severity of stages. The results of RT-qPCR and immunohistochemistry were consistent with each other. Furthermore, The correlation between the mRNA expression of BDNF, TrKB in eutopic endometrium, and dysmenorrhea VAS score revealed that r=0.52 and 0.56, respectively (P<0.05). And when it came to BDNF, TrKB in eutopic endometrium, the correlation (r) was 0.82 (P<0.05).Conclusions: BDNF and TrKB may play essential roles in promoting disease progression during the development of endometriosis, and are closely related to dysmenorrhea caused by endometriosis.

Estrogen affects endometrial cellular proliferation by regulating the expression of the c-myc gene. B-cell translocation gene 1 (BTG1), a translocation partner of the c-myc, is a tumor suppressor gene that promotes apoptosis and negatively regulates cellular proliferation and cell-to-cell adhesion. The aim of this study was to determine the role of BTG1 in the pathogenesis of endometriosis. BTG1 mRNA and protein expression was evaluated in eutopic and ectopic endometrium of 30 patients with endometriosis (endometriosis group), and in eutopic endometrium of 22 patients without endometriosis (control group). The effect of BTG1 downregulation on cellular migration, proliferation, and apoptosis was evaluated using transfection of primarily cultured human endometrial stromal cells (HESCs) with BTG1 siRNA. BTG1 mRNA expression level of eutopic and ectopic endometrium of endometriosis group were significantly lower than that of the eutopic endometrium of the control group. Migration and wound healing assays revealed that BTG1 downregulation resulted in a significant increase in migration potential of HESCs, characterized by increased expression of matrix metalloproteinase 2 (MMP2) and MMP9. Downregulation of BTG1 in HESCs significantly reduced Caspase 3 expression, indicating a decrease in apoptotic potential. In conclusion, our data suggest that downregulation of BTG1 plays an important role in the pathogenesis of endometriosis.

Background: Effort tolerance and daily physical activity (DPA) are predictive of quality of life and survival in COPD patients, but still remain difficult to assess based on their daily life. The aim of this study was: how to relate pedometry to other classic parameters commonly used in pulmonary rehabilitation (PR). Methods: DPA was evaluated through pedometry. 74 patients with COPD, aged 63.55 ± 8.73 (12 stage II, FEV1 = 60.16 ± 7.78%), (29 stage III, FEV1 = 39.07 ± 6.30%), (33 stage IV, FEV1 = 23.1 ± 7.18%). The monitoring was conducted for a period of 7 days before and 6 months after a pulmonary rehabilitation program (PRP) of 3 weeks. A control group consisting of 21 patients with stable COPD was evaluated initially, but they did not undergo Pulmonary Rehabilitation Program (PRP). After 6 months the patients were re-evaluated using the same parameters. Results and discussion: The values are widely dispersed, with a maximum of 17,420 and minimum of 964 steps/24hrs. The average values acquired were: the lowest in COPD stage IV (2476→3112 steps/24 hrs, p < 0.0001), still with the highest increase over 6 months of PR + 636steps/24hrs; in COPD stage III the increase of DPA was + 597steps/24hrs over 6 months (5627→6224, p < 0.0001), COPD stage II registered the lowest increase + 540steps/24hrs (8724→9264, p < 0.13), probably because the subjects belonging to this stage had the best preserved DPA. The results show moderate correlation between pedometry and the 6MWT and the SGQ. (r = 0.5-0.7). However it demonstrated the positive effects of PRP, even after 6 months. Conclusions: DPA decreases with increasing COPD stage, it is fluctuant with every subject, dependent on clinical status, weather and daily schedule. Wearing pedometers is very easy and motivational, provided that patients realize that they are being “watched”.

Background: Nitric oxide (NO), an endogenous product of L-arginine oxidation, seems to account for the vasodilatatory effect of the endothelium-derived relaxing factor. It was the aim of the present study to measure serum nitrate concentrations, the degradation product of nitric oxide in patients with peripheral arterial occlusive disease (PAOD). Patients and methods: 20 patients with PAOD in Fontaine stage IIb, 10 patients in stage III and IV respectively were included in the study. Serum samples for determination of nitrate were taken at admission after fasting overnight. Nitrate concentrations were determined using a recently developed high performance liquid chromatography which allows direct measurement of nitrate. The control group comprised 14 age and risk factor matched volunteers. Results: We found significantly increased nitrate concentrations in patients with PAOD compared to the control group [stage IIb: 6.65 ± 1.58 mumol/l; stage III: 6.94 ± 1.85 mumol/l, stage IV: 7.05 ± 1.16 mumol/l; control: 4.41 ± 1.24 mumol/l], however no significance was calculated within the different PAOD groups. There was no association of either diabetes mellitus, hypertension and smoking behaviour with increased nitrate levels. Conclusion: These data might indicate that NO might be involved in adaptive vasodilatation already in the early phase of the disease. The source of nitrate in PAOD patients, however, remains unclear.

5597 Objective: To document the rate of clinically significant venous thromboembolism (VTE) in patients with clear cell carcinoma of the endometrium (CCC-E). Methods: Institutional review board (IRB) permission was obtained for retrospective record review. The pathology database at our institution located cases of CCCs over the time period 1994–2004. Controls with high grade endometrial cancers were matched for stage, age and date of diagnosis. All patients underwent surgical staging with gynecologic oncology staff surgeons and all patients received VTE prophylaxis peri-operatively. Records were reviewed and data were collected regarding patient age, tumor stage, body mass index, surgical procedure, adjuvant therapy, survival, and presence of VTE. All pathology was reviewed at the MGH. Results: Thirty-nine cases of CCC-E were identified. Complete clinical data were available for 29 cases. Age ranged from 38–85 (mean 64.6) years. 35% of patients had stage I tumors, 10% stage II, 27.5% stage III, and 27.5% had stage IV tumors. 58 age and stage matched controls were selected. The majority were grade 3 endometrioid cancers (50%) with the remainder being serous (35%), mixed histology (7%), carcinosarcoma (5%), and undifferentiated carcinoma (3%). The majority of the control patients had a higher BMI than the case patients. Overall there were 18 VTE events, 10 (34.5%) in those with CCC-E and 8 (13.8%) controls p = 0.046. A higher proportion of VTE occurred in those with stage III/IV disease (n=16) as compared to those with early stage (n =2) p =0.01. When considering the timing of VTE, the VTE observed in those with CCC-E occurred at presentation or with disease recurrence (8 vs 1) while nearly all VTE in the control group occurred in the postoperative period. (7 vs 2). This was statistically significant p =0.01 Conclusion: Patients with CCC-E are at increased risk of VTE compared to patients with other high- risk endometrial cancers. This is particularly true for those with advanced stage disease. Presentation with a VTE and postmenopausal bleeding should raise the suspicion for CCC-E. Likewise, in those with known CCC-E development of a VTE may be a harbinger of recurrence. Consideration should be given to extended prophylaxis in patients with CCC-E to prevent VTE. No significant financial relationships to disclose.

Abstract Intrinsic alignments (IAs) of galaxies are an important contaminant for cosmic shear studies, but the modelling is complicated by the dependence of the signal on the source galaxy sample. In this paper, we use the halo model formalism to capture this diversity and examine its implications for Stage-III and Stage-IV cosmic shear surveys. We account for the different IA signatures at large and small scales, as well for the different contributions from central/satellite and red/blue galaxies, and we use realistic mocks to account for the characteristics of the galaxy populations as a function of redshift. We inform our model using the most recent observational findings: we include a luminosity dependence at both large and small scales and a radial dependence of the signal within the halo. We predict the impact of the total IA signal on the lensing angular power spectra, including the current uncertainties from the IA best-fits to illustrate the range of possible impact on the lensing signal: the lack of constraints for fainter galaxies is the main source of uncertainty for our predictions of the IA signal. We investigate how well effective models with limited degrees of freedom can account for the complexity of the IA signal. Although these lead to negligible biases for Stage-III surveys, we find that, for Stage-IV surveys, it is essential to at least include an additional parameter to capture the redshift dependence.

Abstract Background Laparoscopic Heller myotomy (HM) has gained acceptance as the gold standard of treatment for achalasia. However, 10–20% of the patients will experience symptom recurrence, thus requiring further treatment including pneumodilations (PD) or revisional surgery. The aim of our study was to assess the long-term outcome of laparoscopic redo HM. Methods Patients who underwent redo HM at our center between 2000 and 2019 were enrolled. Postoperative outcomes of redo HM patients (redo group) were compared with that of patients who underwent primary laparoscopic HM in the same time span (control group). For the control group, we randomly selected patients matched for age, sex, FU time, Eckardt score (ES), previous PD, and radiological stage. Failure was defined as an Eckardt score > 3 or the need for re-treatment. Results Forty-nine patients underwent laparoscopic redo HM after failed primary HM. A new myotomy on the right lateral wall of the EGJ was the procedure of choice in the majority of patients (83.7%). In 36 patients (73.5%) an anti-reflux procedure was deemed necessary. Postoperative outcomes were somewhat less satisfactory, albeit comparable to the control group; the incidence of postoperative GERD was higher in the redo group (p < 0.01). At a median 5-year FU time, a good outcome was obtained in 71.4% of patients in the redo group; further 5 patients (10.2%) obtained a long-term symptom control after complementary PD, thus bringing the overall success rate to 81.6%. Stage IV disease at presentation was independently associated with a poor outcome of revisional LHD (p = 0.003). Conclusions This study reports the largest case series of laparoscopic redo HM to date. The procedure, albeit difficult, is safe and effective in relieving symptoms in this group of patients with a highly refractory disease. The failure rate, albeit not significantly, and the post-operative reflux are higher than after primary HM. Patients with stage IV disease are at high risk of esophagectomy.

The aim of the analysis was for the first time to assess the expression of genes encoding IL-21 and IL-22 at the mRNA level in ovarian tumor specimens and the concentration of these parameters in serum and peritoneal fluid in patients with ovarian serous cancer. The levels of IL-21 and IL-22 transcripts were evaluated with the use of the real-time RT-qPCR. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of proteins. Quantitative analysis of IL-21 gene mRNA in the tumor tissue showed the highest activity in the G1 degree of histopathological differentiation and was higher in G1 compared to the control group. The concentration of IL-21 and IL-22 in the serum and in the peritoneal fluid of women with ovarian cancer varied depending on the degree of histopathological differentiation of the cancer and showed statistical variability compared to controls. The conducted studies have shown that the local and systemic changes in the immune system involving IL-21 and IL-22 indicate the participation of these parameters in the pathogenesis of ovarian cancer, and modulation in the IL-21/IL-22 system may prove useful in the development of new diagnostic and therapeutic strategies used in patients, which require further research.

We compared the prevalence of ultrasound signs of adenomyosis in women with endometriosis who underwent surgery to those who were managed conservatively. This was a retrospective study of women evaluated at a tertiary endometriosis referral center who underwent 2D/3D transvaginal ultrasound. Adenomyosis diagnosis was based on the presence of at least three sonographic signs. The study group subsequently underwent laparoscopic surgery while the control group continued conservative management. Statistical analysis compared the two groups for demographics, symptoms, clinical data, and sonographic findings. The study and control groups included 244 and 158 women, respectively. The presence of any, 3+, or 5+ sonographic signs of adenomyosis was significantly more prevalent in the study group (OR = 1.93–2.7, p < 0.004, 95% CI; 1.24–4.09). After controlling for age, for all findings but linear striations, the OR for having a specific feature was higher in the study group. Women in the study group with ≥ 5 sonographic signs of adenomyosis had more than twice the risk of experiencing infertility (OR = 2.31, p = 0.012, 95% CI; 1.20–4.45). Sonographic signs of adenomyosis are more prevalent in women with symptomatic endometriosis who underwent surgery compared with those who continued conservative management. Women with 5+ findings have a significantly increased risk of infertility. Adenomyosis on ultrasound should be considered in the management decisions regarding these patients.
