Meta-Analysis
BACKGROUND
Anemia in pregnancy is a serious threat to maternal and child health and is a major public health problem. However, the risk factors associated with its incidence are unclear and controversial.
METHODS
PubMed, Ovid Embase, Web of Science, and Cochrane databases were systematically searched (inception to June 27, 2022). The screening of search results, extraction of relevant data, and evaluation of study quality were performed independently by two reviewers.
RESULTS
A total of 51 studies of high quality (NOS score ≥ 7) were included, including 42 cross-sectional studies, six case-control studies, and three cohort studies. Meta-analysis showed that infected parasite, history of malarial attack, tea/coffee after meals, meal frequency ≤ 2 times per day, frequency of eating meat ≤ 1 time per week, frequency of eating vegetables ≤ 3 times per week, multiple pregnancies, multiparous, low household income, no antenatal care, rural residence, diet diversity score ≤ 3, have more than 3 children, history of menorrhagia, underweight, family size ≥ 5, middle upper arm circumference < 23, second trimester, third trimester, birth interval ≤ 2 year were all risk factors for anemia in pregnancy.
CONCLUSIONS
Prevention of anemia in pregnancy is essential to promote maternal and child health. Sufficient attention should be paid to the above risk factors from the social level and pregnant women's own aspects to reduce the occurrence of anemia in pregnancy.

Meta-Analysis Review
BACKGROUND
Menstrual hygiene management (MHM) and practices by adolescent females of low and middle-income countries (LMICs) are a severe public health issue. The current systematic review and meta-analysis aimed to estimate the pooled proportion of the hygiene practices, menstrual problems with their associated factors, and the effectiveness of educational interventions on menstrual hygiene among adolescent school girls in India.
METHODS
PRISMA checklist and PICO guidelines were used to screen the scientific literature from 2011 to 2021. The Newcastle-Ottawa Scale was used to assess the quality of studies. Four themes were developed for data analysis, including hygiene practices, type of absorbent used, menstruation associated morbidities and interventions performed regarding menstruation. Eighty-four relevant studies were included and a meta-analysis, including subgroup analysis, was performed.
RESULTS
Pooled data revealed a statistically significant increase in sanitary pad usage "(SMD = 48.83, 95% CI = 41.38-57.62, p < 0.00001)" and increased perineum practices during menstruation "(SMD = 55.77, 95% CI = 44.27-70.26, p < 0.00001)". Results also reported that most prevalent disorders are dysmenorrhea "(SMD = 60.24, 95% CI = 50.41-70.06, p < 0.0001)", Pre-menstrual symptoms "(SMD = 62.67, 95% CI = 46.83-78.50, p < 0.00001)", Oligomenorrhea "(SMD = 23.57, CI = 18.05-29.10, p < 0.00001), Menorrhagia "(SMD = 25.67, CI = 3.86-47.47, p < 0.00001)", PCOS "(SMD = 5.50, CI = 0.60-10.40, p < 0.00001)", and Polymenorrhea "(SMD = 4.90, CI = 1.87-12.81, p < 0.0001)". A statistically significant improvement in knowledge "(SMD = 2.06, 95% CI = 0.75-3.36, p < 0.00001)" and practice "(SMD = 1.26, 95% CI = 0.13-2.65, p < 0.00001)" on menstruation was observed. Infections of the reproductive system and their repercussions can be avoided with better awareness and safe menstruation practices.
CONCLUSIONS
Learning about menstrual hygiene and health is essential for adolescent girls' health education to continue working and maintaining hygienic habits. Infections of the reproductive system and their repercussions can be avoided with better awareness and safe menstruation practices.

Review
INTRODUCTION
Menorrhagia limits normal activities, and causes anaemia in two-thirds of women with objective menorrhagia (loss of 80 mL blood per cycle). Prostaglandin disorders may be associated with idiopathic menorrhagia, and with heavy bleeding due to fibroids, adenomyosis, or use of intrauterine devices (IUDs). Fibroids have been found in 10% of women with menorrhagia overall, and in 40% of women with severe menorrhagia; but half of women having a hysterectomy for menorrhagia are found to have a normal uterus.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of medical treatments for menorrhagia? What are the effects of surgical treatments for menorrhagia? What are the effects of endometrial thinning before endometrial destruction in treating menorrhagia? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations, such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 39 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following medical interventions: combined pill, danazol, etamsylate, gonadorelin analogues, intrauterine progesterone, non-steroidal anti-inflammatory drugs (NSAIDs), progestogens, and the following surgical interventions: dilatation and curettage, endometrial destruction, and hysterectomy.

Meta-Analysis Review
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.

Review
INTRODUCTION
Menorrhagia limits normal activities, and causes anaemia in two thirds of women with objective menorrhagia (loss of 80 mL blood per cycle). Prostaglandin disorders may be associated with idiopathic menorrhagia, and with heavy bleeding due to fibroids, adenomyosis, or use of intrauterine devices (IUDs). Fibroids have been found in 10% of women with menorrhagia overall, and in 40% of women with severe menorrhagia; but half of women having a hysterectomy for menorrhagia are found to have a normal uterus.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of medical treatments for menorrhagia? What are the effects of surgical treatments for menorrhagia? What are the effects of endometrial thinning before endometrial destruction in treating menorrhagia? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 39 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following medical interventions: combined pill, danazol, etamsylate, gonadorelin analogues, intrauterine progesterone, non-steroidal inflammatory drugs (NSAIDs), progestogens, and the following surgical interventions: dilatation and curretage, endometrial destruction, and hysterectomy.

Obstetrics and Gynecology Jul 2023To assess the risk of hysterectomy after nonresectoscopic endometrial ablation in patients with heavy menstrual bleeding. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To assess the risk of hysterectomy after nonresectoscopic endometrial ablation in patients with heavy menstrual bleeding.
DATA SOURCES
The EMBASE, MEDLINE, ClinicalTrials.gov and Cochrane databases were searched for eligible articles from inception until June 13, 2022. We used combinations of search terms for endometrial ablation and hysterectomy.
METHODS OF STUDY SELECTION
Articles included in the review described the incidence of hysterectomy at a specific point in time after ablation with a minimum follow-up duration of 12 months.
TABULATION, INTEGRATION, AND RESULTS
The literature search yielded a total of 3,022 hits. A total of 53 studies met our inclusion and exclusion criteria, including six retrospective studies, 24 randomized controlled trials, and 23 prospective studies. A total of 48,071 patients underwent endometrial ablation between 1992 and 2017. Follow-up duration varied between 12 and 120 months. Analyses per follow-up moment showed 4.3% hysterectomy rate at 12 months of follow-up (n=29 studies), 11.1% at 18 months (n=1 study), 8.0% at 24 months (n=11 studies), 10.2% at 36 months (n=12 studies), 7.6% at 48 months (n=2 studies), and 12.4% at 60 months (n=6 studies). Two studies reported a mean hysterectomy rate at 10 years after ablation of 21.3%. Minimal clinically relevant differences in hysterectomy rates were observed among the different study designs. Furthermore, we found no significant differences in hysterectomy rate among the different nonresectoscopic endometrial ablation devices.
CONCLUSION
The risk of hysterectomy after endometrial ablation seems to increase from 4.3% after 1 year to 12.4% after 5 years. Clinicians can use the results of this review to counsel patients about the 12% risk of hysterectomy 5 years after endometrial ablation.

Review
INTRODUCTION
Between 50% and 77% of women may have fibroids, depending on the method of diagnosis used. Fibroids may be asymptomatic, or may present with menorrhagia, pain, mass and pressure effects, infertility, or recurrent pregnancy loss. Risk factors for fibroids include obesity, having no children, and no long-term use of the oral contraceptive pill. Fibroids tend to shrink or fibrose after the menopause.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of surgical/interventional radiological treatments in women with fibroids? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2014 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
Five studies were included. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: magnetic resonance-guided focused ultrasound surgery versus no/sham treatment; magnetic resonance-guided focused ultrasound surgery versus other interventions (hysterectomy, myomectomy, hysteroscopic resection, rollerball endometrial ablation, thermal balloon ablation, thermal myolysis with laser); uterine artery embolisation versus no/sham treatment; uterine artery embolisation versus hysterectomy; uterine artery embolisation versus myomectomy; uterine artery embolisation versus other interventions (magnetic resonance-guided focused ultrasound surgery, hysteroscopic resection, rollerball endometrial ablation, thermal balloon ablation, thermal myolysis with laser).

Review
'Menorrhagia', or heavy menstrual bleeding, is a common problem affecting women. The principal driver for treatment is women's experience of its interference in their lives, so a measure of quality of life (QoL) is increasingly used as the primary outcome to assess treatment success. QoL measures need to accurately reflect women's concerns as these measures are often used to inform resource allocation decisions within the healthcare service. Healthcare decision-makers often advocate the use of generic measures so as to achieve consistency when making decisions. Generic measures, by definition, have a broad focus on QoL in contrast to disease-specific measures that focus on dimensions of health relevant to the condition. We report a systematic review of studies that have either used or assessed economic outcome measures in menorrhagia, and present criteria for assessing which measure is the most appropriate. Studies including women presenting with menorrhagia, and using or assessing economic measures were sought by searching nine electronic databases. Fifty-six eligible studies were identified. A narrative synthesis was most suitable to the review question. Eleven studies assessed the psychometric properties of the outcome measures, twelve studies applied the measures in an economic evaluation, and thirty-three used them in effectiveness studies. Mixed results on the psychometric properties of the instruments were observed. Studies were often found to include both a disease-specific and a generic measure. We found no consensus on the most appropriate economic outcome measure to use when assessing the cost-effectiveness of treatment for menorrhagia. This is an important finding as QoL is the primary focus for treatment decisions. The cyclical nature of the condition has a large impact on the reliability and validity of outcome measurement. Alternative measures, such as willingness-to-pay, which embrace more than health and avoid standard recall periods should be explored.

Review
BACKGROUND
Optimal peri-operative management for women with Von Willebrand disease (VWD) and heavy menstrual bleeding (HMB) remains undetermined.
AIM AND METHODS
To evaluate (pre)operative management in relation to (post)operative bleeding after endometrial ablation (EA) and hysterectomy in VWD women with HMB by performing a database search between 1994 and 2023.
RESULTS
Eleven cohort studies and 1 case-report were included, of overall 'low' quality, describing 691 operative procedures. Prophylaxis (Desmopressin, clotting factor concentrates or tranexamic acid) to prevent bleeding was described in 100% (30/30) of EA procedures and in 4% (24/661) of hysterectomies. Bleeding complications despite prophylaxis were described in 13% (3/24) of hysterectomies vs 0% (0/30) in EA.
CONCLUSION
VWD women often seem to experience bleeding complications during hysterectomy and all women with VWD received preprocedural hemostatic agents during EA, indicating potential under- and overdosing of current prophylactic strategies. Prospective studies are needed to determine the optimal (pre)operative strategy for gynecological surgical procedures in women with VWD.

Review
INTRODUCTION
Although hereditary von Willebrand disease (VWD) is the most common bleeding disorder, its epidemiology is not well understood. A systematic review (PROSPERO CRD42020197674/CRD42021244374) on the epidemiology/burden of illness of VWD was conducted to better understand patients' unmet needs.
METHODS
Observational studies (published January 1, 2010 to April 14, 2021) were identified in MEDLINE and Embase databases, using free-text keywords and thesaurus terms for VWD and outcomes of interest. Pragmatic web-based searches of the gray literature, including conference abstracts, were performed, and reference lists of retained publications were manually searched for additional sources. Case reports and clinical trials (phase 1-3) were excluded. Outcomes of interest were incidence, prevalence, mortality, patient characteristics, burden of illness, and therapeutic management/treatments currently used for VWD.
RESULTS
Of the 3095 identified sources, 168 were included in this systematic review. Reported VWD prevalence (22 sources) ranged from 108.9 to 2200 per 100,000 in population-based studies and from 0.3 to 16.5 per 100,000 in referral-based studies. Reported times between first symptom onset and diagnosis (two sources; mean 669 days; median 3 years) highlighted gaps in timely VWD diagnosis. Bleeding events reported in 72-94% of the patients with VWD (all types; 27 sources) were mostly mucocutaneous including epistaxis, menorrhagia, and oral/gum bleeding. Poorer health-related quality of life (three sources) and greater health care resource utilization (three sources) were reported for patients with VWD than in general populations.
CONCLUSION
Available data suggest that patients with VWD experience high disease burden in terms of bleeding, poor quality of life, and health care resource utilization.
