Abstract
Background The application of artificial intelligence (AI) powered algorithm in clinical decision-making is globally popular among clinicians and medical scientists. In this research endeavor, we harnessed the capabilities of AI to enhance the precision of hysteroscopic myomectomy procedures. Methods Our multidisciplinary team developed a comprehensive suite of algorithms, rooted in deep learning technology, addressing myomas segmentation tasks. We assembled a cohort comprising 56 patients diagnosed with submucosal myomas, each of whom underwent magnetic resonance imaging (MRI) examinations. Subsequently, half of the participants were randomly designated to undergo AI-augmented procedures. Our AI system exhibited remarkable proficiency in elucidating the precise spatial localization of submucosal myomas. Results The results of our study showcased a statistically significant reduction in both operative duration (41.32 ± 17.83 minutes vs. 32.11 ± 11.86 minutes, p=0.03) and intraoperative blood loss (10.00 (6.25-15.00) ml vs. 10.00 (5.00-15.00) ml, p=0.04) in procedures assisted by AI. Conclusion This work stands as a pioneering achievement, marking the inaugural deployment of an AI-powered diagnostic model in the domain of hysteroscopic surgery. Consequently, our findings substantiate the potential of AI-driven interventions within the field of gynecological surgery.

Abstract
BACKGROUND Heavy menstrual bleeding (HMB) is excessive menstrual blood loss that interferes with women's quality of life, regardless of the absolute amount of bleeding. It is a very common condition in women of reproductive age, affecting 2 to 5 of every 10 women. Diverse treatments, either medical (hormonal or non-hormonal) or surgical, are currently available for HMB, with different effectiveness, acceptability, costs and side effects. The best treatment will depend on the woman's age, her intention to become pregnant, the presence of other symptoms, and her personal views and preferences. OBJECTIVES To identify, systematically assess and summarise all evidence from studies included in Cochrane Reviews on treatment for heavy menstrual bleeding (HMB), using reviews with comparable participants and outcomes; and to present a ranking of the first- and second-line treatments for HMB. METHODS We searched for published Cochrane Reviews of HMB interventions in the Cochrane Database of Systematic Reviews. The primary outcomes were menstrual bleeding and satisfaction. Secondary outcomes included quality of life, adverse events and the requirement of further treatment. Two review authors independently selected the systematic reviews, extracted data and assessed quality, resolving disagreements by discussion. We assessed review quality using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) 2 tool and evaluated the certainty of the evidence for each outcome using GRADE methods. We grouped the interventions into first- and second-line treatments, considering participant characteristics (desire for future pregnancy, failure of previous treatment, candidacy for surgery). First-line treatments included medical interventions, and second-line treatments included both the levonorgestrel-releasing intrauterine system (LNG-IUS) and surgical treatments; thus the LNG-IUS is included in both groups. We developed different networks for first- and second-line treatments. We performed network meta-analyses of all outcomes, except for quality of life, where we performed pairwise meta-analyses. We reported the mean rank, the network estimates for mean difference (MD) or odds ratio (OR), with 95% confidence intervals (CIs), and the certainty of evidence (moderate, low or very low certainty). We also analysed different endometrial ablation and resection techniques separately from the main network: transcervical endometrial resection (TCRE) with or without rollerball, other resectoscopic endometrial ablation (REA), microwave non-resectoscopic endometrial ablation (NREA), hydrothermal ablation NREA, bipolar NREA, balloon NREA and other NREA. MAIN RESULTS We included nine systematic reviews published in the Cochrane Library up to July 2021. We updated the reviews that were over two years old. In July 2020, we started the overview with no new reviews about the topic. The included medical interventions were: non-steroidal anti-inflammatory drugs (NSAIDs), antifibrinolytics (tranexamic acid), combined oral contraceptives (COC), combined vaginal ring (CVR), long-cycle and luteal oral progestogens, LNG-IUS, ethamsylate and danazol (included to provide indirect evidence), which were compared to placebo. Surgical interventions were: open (abdominal), minimally invasive (vaginal or laparoscopic) and unspecified (or surgeon's choice of route of) hysterectomy, REA, NREA, unspecified endometrial ablation (EA) and LNG-IUS. We grouped the interventions as follows. First-line treatments Evidence from 26 studies with 1770 participants suggests that LNG-IUS results in a large reduction of menstrual blood loss (MBL; mean rank 2.4, MD -105.71 mL/cycle, 95% CI -201.10 to -10.33; low certainty evidence); antifibrinolytics probably reduce MBL (mean rank 3.7, MD -80.32 mL/cycle, 95% CI -127.67 to -32.98; moderate certainty evidence); long-cycle progestogen reduces MBL (mean rank 4.1, MD -76.93 mL/cycle, 95% CI -153.82 to -0.05; low certainty evidence), and NSAIDs slightly reduce MBL (mean rank 6.4, MD -40.67 mL/cycle, -84.61 to 3.27; low certainty evidence; reference comparator mean rank 8.9). We are uncertain of the true effect of the remaining interventions and the sensitivity analysis for reduction of MBL, as the evidence was rated as very low certainty. We are uncertain of the true effect of any intervention (very low certainty evidence) on the perception of improvement and satisfaction. Second-line treatments Bleeding reduction is related to the type of hysterectomy (total or supracervical/subtotal), not the route, so we combined all routes of hysterectomy for bleeding outcomes. We assessed the reduction of MBL without imputed data (11 trials, 1790 participants) and with imputed data (15 trials, 2241 participants). Evidence without imputed data suggests that hysterectomy (mean rank 1.2, OR 25.71, 95% CI 1.50 to 439.96; low certainty evidence) and REA (mean rank 2.8, OR 2.70, 95% CI 1.29 to 5.66; low certainty evidence) result in a large reduction of MBL, and NREA probably results in a large reduction of MBL (mean rank 2.0, OR 3.32, 95% CI 1.53 to 7.23; moderate certainty evidence). Evidence with imputed data suggests hysterectomy results in a large reduction of MBL (mean rank 1.0, OR 14.31, 95% CI 2.99 to 68.56; low certainty evidence), and NREA probably results in a large reduction of MBL (mean rank 2.2, OR 2.87, 95% CI 1.29 to 6.05; moderate certainty evidence). We are uncertain of the true effect for REA (very low certainty evidence). We are uncertain of the effect on amenorrhoea (very low certainty evidence). Evidence from 27 trials with 4284 participants suggests that minimally invasive hysterectomy results in a large increase in satisfaction (mean rank 1.3, OR 7.96, 95% CI 3.33 to 19.03; low certainty evidence), and NREA also increases satisfaction (mean rank 3.6, OR 1.59, 95% CI 1.09 to 2.33; low certainty evidence), but we are uncertain of the true effect of the remaining interventions (very low certainty evidence). AUTHORS' CONCLUSIONS Evidence suggests LNG-IUS is the best first-line treatment for reducing menstrual blood loss (MBL); antifibrinolytics are probably the second best, and long-cycle progestogens are likely the third best. We cannot make conclusions about the effect of first-line treatments on perception of improvement and satisfaction, as evidence was rated as very low certainty. For second-line treatments, evidence suggests hysterectomy is the best treatment for reducing bleeding, followed by REA and NREA. We are uncertain of the effect on amenorrhoea, as evidence was rated as very low certainty. Minimally invasive hysterectomy may result in a large increase in satisfaction, and NREA also increases satisfaction, but we are uncertain of the true effect of the remaining second-line interventions, as evidence was rated as very low certainty.

Identification and verification of effective components of Huanghuai for dysfunctional uterine bleeding based on network pharmacology and molecular docking. CHINESE HERBAL MEDICINES 2021; 13:177-188. [PMID: 36117506 PMCID: PMC9476634 DOI: 10.1016/j.chmed.2020.08.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Revised: 07/25/2020] [Accepted: 08/05/2020] [Indexed: 12/03/2022] Open
Abstract
Objective The Huanghuai (HH), which is made from the dried roots of Scutellaria baicalensis (Huangqin in Chinese) and the dried flowers and buds of Sophora japonica (Huaihua in Chinese), is a traditional Chinese formula used to treat dysfunctional uterine bleeding (DUB) (Benglou in Chinese) and proven to treat hemostasis effectively in our previous study. Network pharmacology and molecule docking were performed to study the underlying mechanism of Huanghuai (HH), and pharmacodynamic experiments were conducted to verify its curative effect. Methods TCMSP, UniProt, GeneCards, STRING, DAVID databases, and Cytoscape 3.7.2 were utilized for the construction of a compound-target-pathway network. Docking the potential effective components with potential targets. The HPLC analysis of the potential effective components was performed. In vivo, the hot plate test model was used to study the analgesic activity, the egg white was used to study the swollen reaction in the sole in mice, and the hemostasis effect was studied by the capillary method, tail-breaking method and abortion uterus test. Results The results showed that six compounds (acacetin, beta-sitosterol, wogonin, baicalein, kaempferol and quercetin) and four potential targets (PTGS2, AKT1, TP53 and TNF) in the compound-target-pathway network were the potential material basis for HH to treat DUB. It can be seen that the binding energy of the acacetin, wogonin, baicalein, beta-sitosterol, kaempferol and quercetin in HH docked with the receptor proteins PTGS2, AKT1, TP53, and TNF were far less than −5.0 kJ/mol, which means the molecules have low conformational energy, stable structure and high binding activity. And the result of HPLC analysis showed that acacetin, wogonin, baicalein, kaempferol and quercetin were the potential effective components of the hemostasis mechanism of HH, beta-sitosterol was removed due to low content. In vivo testing of the potential effective components, it revealed that the group of potential effective components identified by HPLC could increase the pain threshold, inhibit the swelling hind paws of mice induced by egg white, reduce the bleeding time and clotting time, reduce uterine bleeding, decrease the uterine weight, increase the content of Ca and ET-1, and reduce the content of NO in uterine homogenate tissue, and decrease of E2 and P content in uterine serum in aborted rats, whose efficacy was equal to HH. Conclusion The results indicated that HH and potential active ingredient groups obtained from network pharmacology can treat DUB and play a hemostatic effect. The results obtained by network pharmacology have certain reliability. This study provides new indications for further mechanism research of HH on DUB and the development of HH or its components as an alternative therapy for patients with DUB. At the same time, the application of network pharmacology strategy may provide a powerful tool for exploring the mechanism of traditional Chinese medicine and discovering new biologically active ingredients.

Abstract
BACKGROUND Many patients with gynecological disorders seek traditional medicine consultations in Asian countries. This study intended to investigate the utilization of traditional Chinese medicine (TCM) in patients with dysfunctional uterine bleeding (DUB) in Taiwan. METHODS We analyzed a cohort of one million individuals randomly selected from the National Health Insurance Research Database in Taiwan. We included 46,337 subjects with newly diagnosed DUB (ICD-9-CM codes 626.8) from January 1, 1997 to December 31, 2010. The patients were categorized into TCM seekers and non-TCM seekers according to their use of TCM. RESULTS Among the subjects, 41,558 (89.69%) were TCM seekers and 4,779 (10.31%) were non-TCM seekers. Patients who were younger tended to be TCM seekers. Most of the patients had also taken Western medicine, especially tranexamic acid and non-steroidal anti-inflammatory drugs (NSAIDs). More than half of TCM seekers (55.41%) received combined treatment with both Chinese herbal remedies and acupuncture. The most commonly used TCM formula and single herb were Jia-Wei-Xiao-Yao-San (Bupleurum and Peony Formula) and Yi-Mu-Cao (Herba Leonuri), respectively. The core pattern of Chinese herbal medicine for DUB patients consisted of Jia-Wei-Xiao-Yao-San, Xiang-Fu (Rhizoma Cyperi), and Yi-Mu-Cao (Herba Leonuri). CONCLUSIONS TCM use is popular among patients with DUB in Taiwan. Further pharmacological investigations and clinical trials are required to validate the efficacy and safety of these items.

Abstract
A growing number of premenopausal women are currently using antithrombotic and/or (dual) antiplatelet therapy for various cardiovascular indications. These may induce or exacerbate abnormal uterine bleeding and more awareness and knowledge among prescribers is required. Heavy and irregular menstrual bleeding is common in women in their forties and may have a variety of underlying causes that require different treatment options. Thus using anticoagulants in premenopausal women demands specific expertise and close collaboration between cardiovascular physicians and gynecologists. In this article we summarize the scope of the problem and provide practical recommendations for the care for young women taking anticoagulants and/or (dual) antiplatelet therapy. We also recommend that more safety data on uterine bleeding with novel anticoagulants in premenopausal women should be obtained.

Abstract
OBJECTIVE To evaluate the reproductive safety and long-term efficacy of hysteroscopic superficial endometrial resection for polypoid endometrium in symptomatic patients (menorrhagia, dysmenorrhea and unexplained infertility). PATIENTS AND METHODS The present retrospective descriptive case series study included 44 patients of reproductive age who underwent superficial hysteroscopic endometrial resection between January 1st, 2004 and December 31, 2009. Reproductive outcome, and the patients' perceptions of menstrual symptoms after the surgical intervention were collected from the clinical notes and a semi-structured telephone interview. RESULTS Of the patients presenting abnormal uterine bleeding, 59% reported long-term improvement of this symptom; of those with dysmenorrhea, 52% reported long-term relief. Among 26 infertile women who wanted to become pregnant immediately after the procedure, 58% succeeded (n=15), with a live-born rate of 38%. The pregnancy rate in primary and secondary infertility cases was respectively 53% (n=8/15) and 64% (n=7/11). CONCLUSION Superficial endometrial resection is an alternative for treating polypoid endometrium when it is associated with menorrhagia, dysmenorrhea and infertility. It treats menstrual symptoms successfully, with no adverse impact on fertility.

Abstract
Pharmacological therapies for the treatment of abnormal uterine bleeding are effective and generally well tolerated. This review presents an evidence-based approach to medical therapy. Selection depends on the etiology and amount of bleeding, need for contraception or preservation of fertility, perimenopause status, and medication efficacy and adverse effects.Available nonhormonal agents include nonsteroidal anti-inflammatory agents, which reduce bleeding by 25% to 35% and improve dysmenorrhea through reduced prostaglandin levels; tranexamic acid, which inhibits plasminogen activator with a 40% to 60% reduction in menstrual blood loss; and intranasal desmopressin, which is an antifibrinolytic for women with an underlying bleeding disorder (eg, von Willebrand disease).Hormonal regimens cause the inhibition of endometrial growth. Cyclic progestogen therapy for 21 days results in a significant reduction in menstrual blood loss. Limited data suggest that oral contraceptives reduce menstrual blood loss by 40% to 50% with decreased breast tenderness and dysmenorrhea and a reduction in risk of uterine and ovarian cancer. The progestin-releasing intrauterine devices are effective up to 97% by 6 months and provide relief of dysmenorrhea and contraception. Long-acting progestogen injections produce amenorrhea and provide contraception but are associated with irregular spotting and reversible bone loss. Danazol leads to endometrial atrophy with a reduced menstrual loss; androgenic adverse effects may be lessened with lower doses or vaginal use. Gonadotrophin agonists lead to ovarian suppression and are used to shrink fibroids or the endometrium preoperatively but are limited by hypoestrogenic adverse events. Emergency use of parenteral conjugated estrogens has a 70% chance of stopping abnormal bleeding but an increased risk of thrombosis.

Abstract
Dysfunctional uterine bleeding (DUB) is defined as excessive or prolonged uterine bleeding in premenopausal women that is not caused by pelvic pathology, medications, systemic disease or pregnancy. It is a common condition that can lead not only to physical symptoms such as iron deficiency, anaemia, cramps and fatigue, but also has significant psychological and social effects that impair a woman's quality of life. Progesterone is highly important in the regulation of menstrual bleeding and a progesterone-deficient anovulatory state is a common cause of DUB. There are a wide range of treatment options available including hormonal therapies (oral cyclical progestogens, depot progestogens, progestogen-releasing intrauterine devices, combined oral contraceptives, danazol, gonadotrophin-releasing hormone analogues and hormone replacement therapy), non-hormonal therapies (non-steroidal anti-inflammatory drugs and antifibrinolytic drugs) and surgery (hysterectomy and endometrial ablation). The choice of appropriate therapy should be based on factors such as the mechanism behind the DUB, which symptoms are most problematic, and the woman's need for fertility or contraception. However, there is currently a lack of clinical evidence to help support these decisions.

Abstract
OBJECTIVE To describe the three-step hysteroscopic endometrial ablation (EA) technique without endometrial preparation, and its long-term outcomes. STUDY DESIGN Four hundred and thirty-eight premenopausal women with menorrhagia or menometrorrhagia underwent three-step hysteroscopic EA, which consists of rollerball ablation of the fundus and cornual regions, a cutting loop endomyometrial resection of the rest of the cavity, and rollerball redessication of the whole pre-ablated uterine cavity. The main outcome measures were menstrual status, level of satisfaction with the procedure, and the need for repeat ablation or hysterectomy. Questionnaires were completed for 385 women (87.9%) with a mean follow-up of 48.2 months. RESULTS One hundred and eighty-four responders (47.8%) reported amenorrhea; 177 (46%) had light to normal flow. One patient (0.3%) underwent repeat ablation and 20 (5.2%) underwent hysterectomy: 15 (3.9%) because of endometrial ablation failure and 5 (1.3%) because of indications unrelated to the ablation (three cases of atypical endometrial hyperplasia and two cases of fibroids). Two hundred and ninety-two patients (75.8%) were very satisfied, and 78 (20.3%) satisfied with the results. No major complications occurred and three women (0.8%) became pregnant during the follow-up period. CONCLUSIONS EA is safe and effective means of treating of menorrhagia and menometrorrhagia in premenopausal women, and helps avoid hysterectomy in 95% of patients suffering from heavy bleeding, with or without uterine fibroids. Women should be informed that the procedure is not contraceptive and that pregnancy is possible after treatment.

Abstract
Ethamsylate (2,5-dihydroxy-benzene-sulfonate diethylammonium salt) is a synthetic hemostatic drug indicated in cases of capillary bleeding. This review covers more than 40 years of intensive clinical and fundamental research with ethamsylate. First, we summarize the large medical literature concerning its clinical efficacy. Of these, well-controlled clinical trials clearly showed the therapeutic efficacy of ethamsylate in dysfunctional uterine bleeding, with the magnitude of blood-loss reduction being directly proportional to the severity of the menorrhagia. Other well-controlled clinical trials showed therapeutic efficacy of ethamsylate in periventricular hemorrhage in very low birth weight babies and surgical or postsurgical capillary bleeding. Second, we review the numerous investigations performed to elucidate the mechanism of action of ethamsylate. Ethamsylate acts on the first step of hemostasis by improving platelet adhesiveness and restoring capillary resistance. Recent studies showed that ethamsylate promotes P-selectin-dependent, platelet adhesive mechanisms. Finally, we compare ethamsylate with other recent hemostatic agents. It is suggested that the place of ethamsylate as a hemostatic agent is that of a mild but well-tolerated drug, particularly useful in dysfunctional uterine bleeding when contraception is not needed.

Abstract
OBJECTIVE This study aims to compare the cost-effectiveness of oral contraceptives (OCs), the levonorgestrel-releasing intrauterine system (LNG-IUS) and surgical management in treating dysfunctional uterine bleeding (DUB) in women not desiring additional children. METHOD A Markov model was constructed from the perspective of the health services payers for a 5-year period. Treatment costs, DUB treatment success rates and contraception success rates were obtained through a literature review. RESULTS In women not responding to an initial trial of OCs, surgical management was more effective than the LNG-IUS (95.5% vs. 92%) but at higher cost (US$4853 vs. US$2796 per woman). Among responders to OCs, continuing treatment with the LNG-IUS instead of OCs was more effective (92% vs. 90.4%) and less expensive (US$2796 vs. US$4711). For women naïve to medical therapy, the LNG-IUS and OCs had similar effectiveness, but cost for the LNG-IUS was lower (US$2796 vs. US$4895). In all scenarios, surgery followed if medical therapy failed; rates of primary method failure were 62.5% with OCs and 34% with the LNG-IUS at 12 months. CONCLUSIONS Treatment strategies employing the LNG-IUS are the most cost-effective in managing DUB, regardless of whether a woman has previously tried OC therapy.

Abstract
OBJECTIVES To investigate the long term risk (mean > 20 years) of death from all causes, cardiovascular disease, and cancer in women who had or had not had a hysterectomy. DESIGN Nested cohort study. SETTING Royal College of General Practitioners' oral contraception study. PARTICIPANTS 7410 women (3705 flagged at the NHS central registries for cancer and death who had a hysterectomy during the oral contraception study and 3705 who were flagged but did not have the operation). MAIN OUTCOME MEASURES Mortality from all causes, cardiovascular disease, and cancer. RESULTS 623 (8.4%) women had died by the end of follow-up (308 in the hysterectomy group and 315 in the non-hysterectomy group). Older women who had had a hysterectomy had a 6% reduced risk of death compared with women of a similar age who did not have the operation (adjusted hazard ratio 0.94, 95% confidence interval 0.75 to 1.18). Compared with young women who did not have a hysterectomy those who were younger at hysterectomy had an adjusted hazard ratio for all cause mortality of 0.82 (0.65 to 1.03). Hysterectomy was not associated with a significantly altered risk of mortality from cardiovascular disease or cancer regardless of age. CONCLUSION Hysterectomy did not increase the risk of death in the medium to long term.
