RESUMO
Objective: This study aims to elucidate the intervention effects of saponin components from Polygala tenuifolia Willd (Polygalaceae) on dementia, providing experimental evidence and new insights for the research and application of saponins in the field of dementia. Materials and Methods: This review is based on a search of the PubMed, NCBI, and Google Scholar databases from their inception to 13 May 2024, using terms such as "P. tenuifolia," "P. tenuifolia and saponins," "toxicity," "dementia," "Alzheimer's disease," "Parkinson's disease dementia," and "vascular dementia." The article summarizes the saponin components of P. tenuifolia, including tenuigenin, tenuifolin, polygalasaponins XXXII, and onjisaponin B, as well as the pathophysiological mechanisms of dementia. Importantly, it highlights the potential mechanisms by which the active components of P. tenuifolia prevent and treat diseases and relevant clinical studies. Results: The saponin components of P. tenuifolia can reduce ß-amyloid accumulation, exhibit antioxidant effects, regulate neurotransmitters, improve synaptic function, possess anti-inflammatory properties, inhibit neuronal apoptosis, and modulate autophagy. Therefore, P. tenuifolia may play a role in the prevention and treatment of dementia. Conclusion: The saponin components of P. tenuifolia have shown certain therapeutic effects on dementia. They can prevent and treat dementia through various mechanisms.
RESUMO
Objective: At present, Alzheimer's disease (AD) lacks effective treatment means, and early diagnosis and intervention are the keys to treatment. Therefore, for mild cognitive impairment (MCI) and AD patients, blood sample analysis using the 4D nonstandard (label-free) proteomic in-depth quantitative analysis, looking for specific protein marker expression differences, is important. These marker levels change as AD progresses, and the analysis of these biomarkers changes with this method, which has the potential to show the degree of disease progression and can be used for the diagnosis and preventive treatment of MCI and AD. Materials and Methods: Patients were recruited according to the inclusion and exclusion criteria and divided into three groups according to scale scores. Elderly patients diagnosed with AD were selected as the AD group (n = 9). Patients diagnosed with MCI were classified into the MCI group (n = 10). Cognitively healthy elderly patients were included in the normal cognition control group (n = 10). Patients' blood samples were used for 4D label-free proteomic in-depth quantitative analysis to identify potential blood biomarkers. The sample size of each group was expanded (n = 30), and the selected biomarkers were verified by enzyme-linked immunosorbent assay (ELISA) to verify the accuracy of the proteomic prediction. Results: Six specific blood markers, namely, APOE, MMP9, UBR5, PLA2G7, STAT5B, and S100A8, were detected by 4D label-free proteomic quantitative analysis. These markers showed a statistically significant upregulation trend in the MCI and AD groups compared with the normal cognition control group (P < 0.05). ELISA results showed that the levels of these six proteins in the MCI group were significantly higher than those in the normal cognition control group, and the levels of these six proteins in the AD group were significantly higher than those in the MCI group (P < 0.05). Conclusion: The plasma levels of APOE, MMP9, UBR5, PLA2G7, STAT5B, and S100A8 in cognitively healthy elderly patients and patients with MCI and AD were significantly different and, more importantly, showed a trend of increasing expression. These results indicate that these six human plasma markers have important diagnostic and therapeutic potential in the identification of cognitive impairment and have value for in-depth research and clinical application.

Background: Colpocleisis is one of traditional surgical procedures for elderly and frail women with advanced pelvic organ prolapse. The occurrence of de novo urinary incontinence following colpocleisis was considered to impair the postoperative quality of life. The incidence of de novo urinary incontinence after colpocleisis has been reported to be ranging from 6.6 % to 27 %. There was an absence of prospective large-sample study to investigate the accurate incidence of de novo urinary incontinence following colpocleisis and the impact on the quality of life till now. Purpose: s The primary objective was to report the incidence of de novo urinary incontinence after colpocleisis. The second objectives were to evaluate the long-term quality of life in patients with de novo urinary incontinence, and to conduct detailed pre- and post-operative evaluations of lower urinary tract symptoms. Methods: This prospective study included 253 patients with symptomatic pelvic organ prolapse who underwent colpocleisis between 2009 and 2021. De novo urinary incontinence was defined as the occurrence of urinary incontinence 3 months postoperatively. All patients were required to complete the Urinary Distress Inventory questionnaire and the Urinary Impact Questionnaire for the evaluation of patients' quality of life, and the Patient Global Impression of Improvement questionnaire for the evaluation of patients' satisfaction. Results: 245 patients (245/253, 96·8 %) completed the 3-month follow-up, and were included in the final analysis. The incidence of de novo urinary incontinence was 5.4 % (10/185). There was no significant difference in the Urinary Distress Inventory -6 scores (22.50 vs. 10.30, P = 0.276) or the subjective satisfaction rate (100 % vs. 98.9 %, P = 0.250) between the patients with or without de novo urinary incontinence at the long-term follow-up. The incidence of voiding difficulty was significantly reduced after colpocleisis (27.8 % vs. 0.0 %, P < 0.001). The patients' quality of life indicated by Urinary Distress Inventory-6 and Urinary Impact Questionnaire-7 scores were significantly improved postoperatively (26.27 vs. 13.39, and 19.13 vs. 6.05, P < 0.05). Conclusion: The incidence of de novo urinary incontinence after colpocleisis was very low. Patients' quality of life, and low urinary tract symptoms were significantly improved after colpocleisis.
RESUMO
BACKGROUNDS: Intraplacental choriocarcinoma (IC) is an extremely rare subtype of gestational choriocarcinoma. The long-term follow-up and reproductive outcomes of IC patients remain unclear. Here, we report a series of 14 cases and conduct a literature review to assess the fertility and recurrence results of this rare disease. RESULTS: Fourteen patients with pathologically confirmed IC treated in Peking Union Medical College Hospital between January 2002 and July 2022 were included in this study. Half of them had metastatic IC and were treated by chemotherapy with or without surgery. Only 1 patient had chemoresistant disease, but she achieved complete remission after immunotherapy. The median follow-up time was 45.5 months (range 4-192), and no recurrence occurred. One metastatic IC patient who achieved remission after chemotherapy had a full-term delivery. Among the 5 patients with fertility demands, 3 abandoned their pursuit of pregnancy because of "fear and worry about choriocarcinoma recurrence". We reviewed a total of 89 cases of IC in English and Chinese literature from 1963 to 2022, and only 5 cases with subsequent pregnancy were reported, all of them were nonmetastatic IC cases. CONCLUSIONS: IC is sensitive to chemotherapy and has good long-term remission and a low recurrence rate. Patients with metastatic or nonmetastatic IC can have good pregnancy results after treatment. Doctors should pay more attention to the psychology of these patients. CLINICAL TRIAL REGISTRATION: N/A.

ETHNOPHARMACOLOGICAL RELEVANCE: Various components of Lonicera japonica Thunb. (LJT) exhibit pharmacological activities, including anti-inflammatory and antioxidant effects. Nevertheless, the relationship between LJT and ferroptosis remains largely unexplored. AIM OF THE STUDY: The purpose of this research was to look into the role of LJT in regulating LPS-induced ferroptosis in ALI and to compare the effects of different parts of LJT. MATERIALS AND METHODS: We established a mice ALI model by treating with LPS. Administered mice with different doses of Lonicerae Japonicae Flos (LJF), Lonicera Japonica Leaves (LJL) and Lonicerae Caulis (LRC) extracts, respectively. The levels of IL-6, IL-1ß, TNF-α, IL-4, IL-10, and PGE2 in bronchoalveolar lavage fluid (BALF) were measured using enzyme-linked immunosorbent assay. Furthermore, the concentrations of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), reactive oxygen species (ROS), and total ferrous ions (Fe2+) in lung tissues were evaluated. Hematoxylin and eosin staining was conducted to examine the morphological structure of lung tissues. Transmission electron microscopy was used to investigate the ultrastructural morphology of mitochondria. Furthermore, the effects of LJT were evaluated via immunohistochemical staining, western blotting, and quantitative real-time polymerase chain reaction analyses. Finally, employing molecular docking and molecular dynamics research techniques, we aimed to identify crucial components in LJT that might inhibit ferroptosis by targeting nuclear factor erythroid 2-related factor 2 (Nrf2) and glutathione peroxidase 4 (GPX4). RESULTS: We observed that pretreatment with LJT significantly mitigated LPS-induced lung injury and suppressed ferroptosis. This was supported by reduced accumulation of pro-inflammatory cytokines, ROS, MDA, and Fe2+, along with increased levels of anti-inflammatory cytokines, SOD, GSH, Nrf2, and GPX4 in the lung tissues of ALI mice. Luteolin-7-O-rutinoside, apigenin-7-O-rutinoside, and amentoflavone in LJT exhibit excellent docking effects with key targets of ferroptosis, Nrf2 and GPX4. CONCLUSIONS: Pretreatment with LJT may alleviate LPS-induced ALI, possibly by suppressing ferroptosis. Our initial results indicate that LJT activates the Nrf2/GPX4 axis, providing protection against ferroptosis in ALI. This finding offers a promising therapeutic candidate for ALI treatment.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common childhood malignancy. The cure rate has reached 90% after conventional chemotherapy and hematopoietic stem cell transplantation (HSCT), but the prognosis of patients with relapsed and refractory (R/R) leukemia is still poor after conventional treatment. Since FDA approved CD19 CAR-T cell (Kymriah) for the treatment of R/R B-ALL, increasing studies have been conducted on CAR-T cells for R/R ALL. Herein, we report the treatment of a patient with ALL who relapsed after allogeneic HSCT, had a complete remission (CR) to murine scFv CD19 CAR-T but relapsed 15 months later. Partial response was achieved after humanized CD19 CAR-T treatment, and the patient finally achieved disease-free survival after sequential CD22 CAR-T treatment. By comparing the treatment results of different CAR-T cells in the same patient, this case suggests that multiple CAR-T therapies are effective and safe in intramedullary and extramedullary recurrence in the same patient, and the expansion of CAR-T cells and the release of inflammatory cytokines are positively correlated with their efficacy. However, further clinical studies with large sample sizes are still needed for further clarification.

Malignant transformations, such as ovarian squamous cell carcinoma (SCC) in ovarian mature cystic teratoma (OMCT), are rare tumors. The management of recurrent disease is still a challenge, and the gene mutations involved remain unclear. We herein report a recurrent case of ovarian SCC with a PIK3CA gene variation and immunohistochemical staining of programmed death-ligand 1 (PD-L1) >10%. This patient achieved clinical remission after platinum-based effective chemotherapy and programmed death 1 (PD-1) immunotherapy.
RESUMO
We aimed to evaluate the long-term effectiveness and safety of Burch colposuspension (BC) for stress urinary incontinence (SUI). In this prospective cohort study, 84 patients with SUI undergoing BC were enrolled from February 2004 to January 2010. Data on long-term subjective success and postoperative complications were collected at clinic visits and by telephone follow-up. During a mean follow-up period of 14.2 years, 68% (57/84) patients completed the follow-up. A total of 68.4% of patients (39/57) reported absence of SUI symptoms, 73.6% (42/57) were subjectively satisfied according to the Patient Global Impression of Improvement, and 68.4% (39/57) reported subjective success regarding urinary symptoms via the Urinary Distress Inventory Short Form. However, 28.1% (16/57) suffered at least one long-term postoperative complication and incident. Specifically, 1 in 25 (4.0%) sexually active patients reported dyspareunia, 3 patients (5.3%) had de novo overactive bladder, and 6 patients (10.5%) reported voiding dysfunction. Four patients (7.0%) reported new onset prolapse symptoms, and 3 patients (5.3%) underwent secondary urinary incontinence surgery. Our study indicated that Burch colposuspension is an effective procedure for SUI, and the cure effect was largely maintained for the 14-year follow-up period, with relatively low complication rates. BC should be considered a surgical option for SUI.

In this work, boron dipyrromethene (BODIPY) is for the first time employed as electron-deficient core (A') to construct an A-D-A'-D-A type nonfused-ring electron acceptor (NFREA) for polymer solar cells (PSCs). Among, cyclopentadithiophene (CPDT) and fluorinated dicyanoindanone (DFIC) are involved as electron-donating (D) bridges and terminal A groups, respectively. Bearing with the steric BODIPY core, tMBCIC exhibits twisted configuration with dihedral angles >45° between BODIPY and CPDT bridges. Thus, compared with the BODIPY-free planar A-D-D-A structured bCIC, reduced aggregation, weakened intramolecular D-A interactions with up-shifted lowest unoccupied molecular orbital by 0.4 eV as well as blueshifted absorption by up to 150 nm is observed in tMBCIC. Moreover, owing to the intrinsic large molar extinction coefficient from BODIPY, promoted light-harvest ability is achieved for tMBCIC, particularly in its blend films. Therefore, PSCs by using PBDB-T as donor, tMBCIC as NFREA afford superior power conversion efficiency (PCE) of 9.22% and higher open-circuit voltage (Voc ) of 0.954 V compared to 4.47% and 0.739 V from bCIC-devices. Moreover, compared to other BODIPY-flanked electron acceptors (<5%) reported so far, BODIPY-cored tMBCIC realizes a remarkable progress in PCE.
RESUMO
Transvaginal meshes repair for treating pelvic organ prolapse (POP) was halted by the U. S. Food and Drug Administration (FDA) because they can lead to severe complications. Therefore, investigations of new therapeutic strategies are urgently needed. Cell-based regenerative therapy holds great promise for the repair and restoration of damaged tissue. Here, we generated a bioengineered graft by seeding human umbilical cord mesenchymal stem cells (HUMSCs) on bioscaffolds to reconstruct the damaged vagina. In the in vitro study, HUMSCs proliferated well and the density was appropriate after 5 days of culture. Besides, we demonstrated that the differentiation potential of HUMSCs was maintained with external growth factor stimulation. The complete transcriptomic profile of HUMSCs revealed that HUMSCs cultured on grafts produced significantly higher levels of proangiogenic cytokines than cells cultured in tissue culture plates (TCPs). Three months after implantation of the bioengineered grafts into ovariectomized (OVX) rhesus monkeys via sacrocolpopexy, extracellular matrix reorganization, large muscle bundle formation, angiogenesis and, mechanical properties of the vagina were enhanced. To our knowledge, this is the first demonstration of the utility of stem cell-based bioengineered grafts for repairing damaged vaginal tissue in rhesus monkeys. These results elucidate a new approach for vagina repair and provide new ideas for treating POP.

OBJECTIVE: The selection of individualized treatment for recurrent cervical cancer is challenging. This study aimed to investigate the impact of various therapies on survival outcomes after recurrence. METHODS: Eligible patients were diagnosed with recurrent cervical cancer between March 2012 and April 2018. Postrecurrence progression-free survival (PFS) and overall survival (OS) were investigated in the whole cohort and in subgroups, categorized by recurrence site and prior radiotherapy history, using a multivariate model that incorporated treatment for primary and recurrent tumors, histological pathology, and FIGO staging. RESULTS: Two hundred and sixty recurrent cervical cancer patients were included. As of March 1, 2020, the median postrecurrence PFS and OS were 7.0 (range 0-94) and 24.0 (1.8-149.1) months, respectively. In a multivariate model measured by PFS, radiotherapy was superior to other therapies for the whole cohort (p=0.029) and recurrence only within the pelvic cavity (p=0.005), but the advantages of radiotherapy disappeared in patients with a history of radiotherapy (p values >0.05). For recurrence only beyond the pelvic cavity, combination therapy resulted in improved PFS (p=0.028). For recurrence both within and beyond the pelvic cavity, no therapy regimen provided additional PFS benefits (p values >0.05). Radiotherapy and combination therapy were also associated with improved postrecurrence OS for recurrence within the pelvic cavity (p=0.034) and only beyond the pelvic cavity (p=0.017), respectively. CONCLUSIONS: In cervical cancer patients, postrecurrence radiotherapy can improve PFS and OS for patients with recurrence within the pelvic cavity and without prior radiotherapy. For recurrence beyond the pelvic cavity or cases with a history of radiotherapy, combination or individualized therapy may provide potential survival benefits.
RESUMO
The association between human papillomavirus (HPV) integration and relevant genomic changes in uterine cervical adenocarcinoma is poorly understood. This study is to depict the genomic mutational landscape in a cohort of 20 patients. HPV+ and HPV- groups were defined as patients with and without HPV integration in the host genome. The genetic changes between these two groups were described and compared by whole-genome sequencing (WGS) and whole-exome sequencing (WES). WGS identified 2916 copy number variations and 743 structural variations. WES identified 6113 somatic mutations, with a mutational burden of 2.4 mutations/Mb. Six genes were predicted as driver genes: PIK3CA, KRAS, TRAPPC12, NDN, GOLGA6L4 and BAIAP3. PIK3CA, NDN, GOLGA6L4, and BAIAP3 were recognized as significantly mutated genes (SMGs). HPV was detected in 95% (19/20) of patients with cervical adenocarcinoma, 7 of whom (36.8%) had HPV integration (HPV+ group). In total, 1036 genes with somatic mutations were confirmed in the HPV+ group, while 289 genes with somatic mutations were confirmed in the group without HPV integration (HPV- group); only 2.1% were shared between the two groups. In the HPV+ group, GOLGA6L4 and BAIAP3 were confirmed as SMGs, while PIK3CA, NDN, KRAS, FUT1, and GOLGA6L64 were identified in the HPV- group. ZDHHC3, PKD1P1, and TGIF2 showed copy number amplifications after HPV integration. In addition, the HPV+ group had significantly more neoantigens. HPV integration rather than HPV infection results in different genomic changes in cervical adenocarcinoma.

OBJECTIVE: To investigate the significance of perioperative levonorgestrel-releasing intrauterine system (LNG-IUS) and/or gonadotropin-releasing hormone agonists (GnRHa) as adjuvant therapy in preventing recurrences or progression of diseases. METHODS: Medical records were collected from patients diagnosed with adenomyosis who underwent uterus-sparing surgeries from March 1, 2012 to December 31, 2018. The associations of perioperative adjuvant therapy with recurrence of disease and symptoms were analyzed with the Kaplan-Meier method and proportional hazards models with hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: A total of 322 eligible patients were included, of whom 173 (58.1%) received perioperative adjuvant therapy. Perioperative adjuvant therapy (HR 0.44, 95% CI 0.22-0.91, P = 0.022) and perioperative GnRHa therapy (HR 0.48, 95% CI 0.24-0.99, P = 0.042) significantly reduced disease recurrence. No patient using perioperative LNG-IUS therapy experienced recurrence. In the multivariate analysis, increased age (>35 years at surgery) was the only risk factor for disease recurrence (HR 2.35, 95% CI 1.01-5.45, P = 0.047). CONCLUSION: Perioperative adjuvant therapy with GnRHa and/or the LNG-IUS can significantly reduce disease recurrence or progression for adenomyosis patients undergoing uterus-sparing surgery. Older patients are more likely to experience disease recurrence.

Alzheimer's disease treatments have been a heavily investigated research area, however, new drugs have failed one after another. Some scientists have begun to reposition drugs, including antimicrobial agents. Here, the treatment effects of nine antimicrobial agents on Alzheimer's disease and their possible therapeutic mechanisms are described to clarify their efficacy. In vivo and in vitro studies are quite encouraging and tend to demonstrate that antimicrobial therapy is effective in Alzheimer's disease. Nevertheless, unsatisfactory clinical efficacy, side effects, and insufficient knowledge have yet to be overcome. Further laboratory and clinical studies are required to recommend antimicrobial treatment regimens.

OBJECTIVE: The effectiveness of various strategies for the post-treatment monitoring of cervical cancer is unclear. This pilot study was conducted to explore recurrence patterns in and diagnostic strategies for patients with uterine cervical cancer who were meticulously followed using a customized monitoring plan. METHODS: The epidemiological and clinical data of patients with recurrent cervical cancer treated from March 2012 to April 2018 at a tertiary teaching hospital were retrospectively collected. The diagnostic methods and their reliability were compared across patients with various clinicopathological characteristics and were associated with survival outcomes. RESULTS: Two hundred sixty-four patients with recurrent cervical cancer were included in the study, among which recurrence occurred in the first three years after the last primary treatment in 214 patients (81.06%). Half of the recurrence events (50.76%) occurred only within the pelvic cavity, and most lesions (78.41%) were multiple in nature. Among all recurrent cases, approximately half were diagnosed based on clinical manifestations (n=117, 44.32%), followed by imaging examinations (n=76, 28.79%), serum tumor markers (n=34, 12.88%), physical examinations (n=33, 12.50%) and cervical cytology with or without high-risk human papillomavirus (hrHPV) testing (n=4, 1.52%). The reliability of the diagnostic methods was affected by the stage (p<0.001), primary treatment regimen (p=0.001), disease-free survival (p=0.022), recurrence site (p=0.002) and number of recurrence sites (p=0.001). Primary imaging methods (sonography and chest X-ray) were not inferior to secondary imaging methods (computed tomography, magnetic resonance imaging and positron emission tomography-computed tomography) in the detection of recurrence. The chest X-ray examination only detected three cases (1.14%) of recurrence. Patients assessed with various diagnostic strategies had similar progression-free and overall survival outcomes. CONCLUSIONS: A meticulous evaluation of clinical manifestations might allow recurrence to be discovered in a timely manner in most patients with cervical cancer. Specific diagnostic methods for revealing recurrence were not associated with the survival outcomes.
RESUMO
OBJECTIVE: The aim of the study was to evaluate sexual function in women before and after tension-free vaginal tape (TVT) surgery for the treatment of stress urinary incontinence (SUI). METHODS: Between August 2014 and August 2018, 105 sexually active patients with SUI who underwent TVT surgery were enrolled in this prospective cohort study. The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire Short Form (PISQ-12) was administered pre- and postoperatively. Statistical analyses were performed using paired-sample t tests. RESULTS: The sexual function of 105 patients 1 year after the TVT procedure improved in 81 (77.1%) patients, remained unchanged in 18 (17.1%) patients, and deteriorated in 6 (5.7%) patients. The mean PISQ-12 score increased from 29.65 at baseline to 33.04 at the 1-year follow-up (Pâ<â0.001). Improvement was prominent in the physical domain of the PISQ-12 (Pâ<â0.001), but the emotional (Pâ=â0.948) and partner-related (Pâ=â0.915) domains showed no significant changes. The increase in the physical domain score caused the increase of the total PISQ-12 score. Compared with preoperative values, there was no significant change in the score of pain during sexual intercourse (Pâ=â0.425) at 1 year after the TVT procedure. Women experienced less coital incontinence (Pâ<â0.001), less fear of incontinence during intercourse (Pâ<â0.001), and less negative emotional reactions (Pâ<â0.001) during intercourse after the TVT operation than before the TVT operation. CONCLUSIONS: Sexual function was improved in patients with SUI after TVT surgery.

INTRODUCTION: Recent studies have revealed that the oncological survival outcomes of minimally invasive radical hysterectomy (MIRH) are inferior to those of abdominal radical hysterectomy (ARH) in early-stage cervical cancer, but the potential reasons are unclear. METHODS AND ANALYSIS: Each expert from 28 study centres participating in a previously reported randomised controlled trial (NCT03739944) will provide successive eligible records of at least 100 patients who accepted radical hysterectomy for early-stage cervical cancer between 1 January 2009 and 31 December 2015. Inclusion criteria consist of a definite pathological evaluation of stages IA1 (with positive lymphovascular space invasion), IA2 and IB1 according to the International Federation of Gynecology and Obstetrics 2009 staging system and a histological subtype of squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma. The primary endpoint is 5-year disease-free survival between the MIRH and ARH groups. The secondary endpoints include the MIRH learning curves of participating surgeons, 5-year overall survival between the MIRH and ARH groups, survival outcomes according to surgical chronology, surgical outcomes and sites of recurrence and potential risk factors that affect survival outcomes. A subgroup analysis in patients with tumour diameter less than 2 cm will follow the similar flow diagram. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of Peking Union Medical College Hospital (registration no. JS-1711), and is also filed on record by all other 27 centres. The results will be disseminated through community events and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03738969.

STUDY OBJECTIVE: Endometriosis is the most common cause of secondary dysmenorrhea among adolescents. Data on postoperative symptoms of the disease in adolescents are limited. In this study we aimed to describe the clinical characteristics and postoperative symptoms of adolescent endometriosis in our center. DESIGN: Retrospective cohort study. SETTING: Tertiary care institution. PARTICIPANTS: Eighty-five adolescents with surgically confirmed endometriosis, age younger than 19 years, were included. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Clinical characteristics including demographic factors, pelvic symptoms, and changes of pelvic pain after surgery. RESULTS: Of 11,236 patients with endometriosis who received surgical treatment between January 2008 and January 2018 in our department, 85 adolescents (85/11,236; 0.76%) were included. The mean age at the time of surgery was 16.3 (±2.4) years and pelvic pain was the main symptoms which occurred in 73/85 (85.9%). Forty-four of the 85 patients (51.8%) had associated genital malformations. The patients with genital malformations tended to present with a younger age at the time of surgery (15.1 ± 2.4 vs 17.6 ± 1.7 years; P < .001) and a shorter duration of symptoms to time of surgery (1.5 ± 1.3 vs 2.3 ± 2.1 years; P = .033). The median follow-up time was 56 months (range, 24-140 months) after surgery, and the pelvic pain had disappeared in 41.7% of patients, improved in 38.3% of patients, and had no change or worsened in 20.0% patients. CONCLUSION: Pelvic pain was the main symptom in adolescents with endometriosis and was greatly improved after surgery. It should also be noted that genital malformation might be an important factor in younger adolescents with endometriosis.

OBJECTIVE: To evaluate the long-term safety and effectiveness of inside-out transobturator tape (tension-free vaginal tape-obturator, TVT-O) for the treatment of stress urinary incontinence (SUI). PATIENTS AND METHODS: Between August 2004 and August 2006, 87 consecutive patients with SUI who underwent TVT-O were enrolled in this prospective cohort study. Patients with mixed UI, or pelvic organ prolapse requiring surgery, were excluded. Data relating to long-term postoperative complications, subjective satisfaction rate (Patient Global Impression of Improvement), objective cure rate (stress test), quality of life (QoL), and sexual function, were collected during follow-up. The Incontinence Impact Questionnaire (IIQ-7) and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) were used to assess QoL and sexual function, respectively. Statistical analyses were performed using paired-sample t-tests. RESULTS: At the 12-year follow-up, 73 patients (84%) were available for evaluation. Overall, the long-term complication rate was 45.2%. De novo overactive bladder was observed in 12.3% of patients. None of the patients reported severe voiding dysfunction that required treatment by tape removal or catheterisation. However, 16 patients (16/73, 21.9%) had voiding changes compared with their preoperative status. Persistent groin pain was reported in 1.4% of the patients, and tape exposure occurred in 5.5%. The subjective satisfaction rate and objective cure rate were 80.8% and 82.2%, respectively. Compared with preoperative scores, the IIQ-7 score decreased significantly (P < 0.05), whilst there was no significant difference in the PISQ-12 score (P = 0.893). CONCLUSIONS: This 12-year follow-up study showed that TVT-O is a highly effective procedure for the treatment of SUI. The long-term complication rate appears to be slightly high, which should raise concern.
