- Abstract
Background: Many risk factors in uterine fibroid development have been identified, but women and their physicians are less aware of the influence of lifestyle on uterine fibroid development. The objective of this systematic review is to investigate and summarize modifiable prognostic factors associated with uterine fibroid development., Methods: Pubmed and Embase were searched for relevant articles according to PRISMA guidelines. References from included articles were screened and when relevant also included. Human in vivo studies on modifiable factors in fibroid development were included. Studies on non-modifiable factors and treatment, in vitro studies and animal studies were excluded. 607 articles were screened and 33 articles were included. Two independent investigators collected data from the report., Results: The strongest risk factor for fibroid development was a high BMI, while the strongest protective factors were a high fruit and vegetable intake and high vitamin D intake., Conclusion: More high-quality studies are necessary to better understand the impact of the abovementioned factors as well as the role they play in the growth of already existing fibroids.

- Abstract
Objectives: Transcervical resection of myoma (TCRM) is a widely implemented treatment for submucous fibroids. The aim of this study is to evaluate the effect of TCRM on menstrual bleeding, fibroid related symptoms and quality of life and hemoglobin (Hb) levels., Study Design: A prospective cohort study was conducted in three teaching hospitals and two academic hospitals in the Netherlands. Patients with HMB (PBAC score > 150) and submucous fibroids (type 0, 1, 2, 3, 4 and hybrid type 2-5) scheduled for TCRM were eligible. At baseline and 3 months after TCRM a Trans Vaginal Ultrasound (TVU) was performed and a Hb sample was taken. Patients filled out the Pictorial Blood Assessment Chart (PBAC) and the Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire at baseline and up to 6 months after surgery. Primary outcome was improvement in PBAC score 6 months after surgery. Secondary outcomes were improvement in PBAC score and Hb level 3 months after surgery and UFS-QOL scores 3 and 6 months after surgery., Results: 126 patients were included and 104 were operated. PBAC were obtained from 98 patients. Six months after surgery, 56.6% of patients went from HMB to normal menstrual bleeding (PBAC < 150). A significant reduction in median PBAC scores of 427 (IQR 198 - 1392) (p <.0001) was found (86% improvement). UFS-QOL scores were obtained from 91 patients. Symptom severity improved from a median of 54 on a scale of 100 (IQR 44-66) at baseline to 22 (IQR 9-41) after 6 months (p <.0001) (59% improvement). Health related quality of life (HRQOL) improved from a median score of 44 on a scale of 100 (IQR 33-62) to 89 (IQR 67-97) 6 months after surgery (p <.0001) (102% improvement)., Conclusion: TCRM significantly reduces the amount of menstrual bleeding, severity of fibroid related symptoms and improves HRQOL in patients with submucous fibroids., (Copyright © 2022 The Authors.

- Abstract
Background: Uterine fibroids present differently, from well vascularised up to calcified, with some causing heavy menstrual bleeding (HMB)., Objectives: To investigate the association between fibroid vascularisation and HMB, other fibroid related symptoms and quality of life (QOL)., Materials and Methods: A single centre pilot study was carried out in the Netherlands. Women with a maximum of two fibroids who chose expectant management were included. 3D sonography including power doppler was performed at baseline and at 3, 6 and 12 months follow up. Women were asked to complete the Pictorial Blood Assessment Chart (PBAC) and Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaires at every visit., Main Outcome Measure: Main outcome measure: The association between fibroid vascularisation and HMB., Results: 53 women were included in the study. Baseline fibroid vascularisation, measured as vascular index (VI) is associated with PBAC score; a 1% higher VI at baseline leads to an 11 point increase in PBAC score over time (RC 10.99, p=0.05, 95% CI -0.15 - 22.12). After correction for the baseline variables ethnicity and fibroid type the association becomes stronger (P<0.05). Fibroid volume at baseline and HMB are also associated: a 1 cm3 larger fibroid leads to 0.6 points increase in PBAC score over time (RC 0.56, p=0.03, 95% CI 0.05 - 1.07)., Conclusions: Conclusions: This study highlights that both fibroid vascularisation and fibroid volume may be associated with an increase in menstrual blood loss, other fibroid related symptoms and QOL over time., What Is New?: What is new? We used 3D power doppler to predict symptomatic fibroids.

- Abstract
Objective: Uterine fibroids can cause a variety of symptoms in women, from heavy menstrual bleeding and dysmenorrhea to bulk symptoms. The Uterine Fibroid Symptom and health-related Quality Of Life questionnaire (UFS-QOL) is a patient-reported outcome measure developed for assessing fibroid-related symptoms in a standardised way. Our aim was to translate and validate the UFS-QOL in Dutch., Design: Validation study., Setting: Patients were recruited by a gynaecologist at the outpatient clinic., Participants: Women with uterine fibroids., Methods: The UFS-QOL was translated into Dutch (UFS-QOL NL) and validated through testing construct validity (comprising of structural validity and hypotheses testing), reliability, responsiveness and interpretability, assessing floor and ceiling effects and minimal important change. An option to answer 'not applicable' was added to the translated questionnaire., Results: 191 women with uterine fibroids completed the UFS-QOL NL at baseline, after 2 weeks and after 3 months. The questionnaire retained the same factor structure after translation (Comparative Fit Index 0.94-0.95; Tucker-Lewis fit Index 0.93-0.95; Root Mean Square Error of Approximation 0.10-0.11) and correlations to other questionnaires (RAND 36, Hospital Anxiety and Depression Scale and Golombok Rust Inventory of Sexual Satisfaction) were generally moderate, as hypothesised (Pearson's r 0.3-0.7). We found a sufficient reliability with intraclass correlation coefficients of approximately 0.8-0.9 for all subscales. Responsiveness was sufficient when testing hypotheses comparing women who had surgery with those who did not. Cronbach's alpha was higher than 0.7 for all subscales, indicating sufficient internal consistency and there were no concerns about floor or ceiling effects. Minimal important change could not be calculated due to low correlation between the different subscales and the anchor question., Conclusions: The results support the measurement properties of the Dutch UFS-QOL for assessing fibroid-related symptoms and health-related quality of life in Dutch women with uterine fibroids., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

- Abstract
Objective: To analyse fibroid vascularisation measured with three-dimensional (3D) power Doppler in relation to absolute fibroid volume change during 12 months of follow up and in relation to fibroid growth rate per year., Design: A prospective cohort study was performed between March 2012 and March 2014., Setting: Outpatient clinic of the VU medical centre, Amsterdam., Population or Sample: All premenopausal women diagnosed with a maximum of two fibroids with expectant management were consecutively included., Methods: Three-dimensional ultrasound including power Doppler was performed at baseline, 3, 6 and 12 months. Volume and vascular parameters were calculated using VOCAL software., Main Outcome Measures: The relationship between vascular index (VI) at baseline and fibroid volume over time was analysed using linear mixed model analyses for repeated measurements. Second, the relationship between VI at baseline and fibroid growth rate per year was calculated using linear regression analyses. Analyses were adjusted for possible confounders., Results: In all, 66 women (mean age 42 years) completed 12 months of follow up without treatment. Baseline fibroid vascularisation (VI) measured with 3D power Doppler is correlated with fibroid volume at 12 months (P = 0.02 ). An increase of 1% in VI at baseline was associated with a 7.00-cm
3 larger fibroid volume at 12 months. Furthermore, vascularisation was also associated with fibroid growth rate per year (P = 0.04)., Conclusion: In women with uterine fibroids without therapy, baseline vascularisation (VI) measured with 3D power Doppler is correlated with absolute fibroid volume change at 12 months and with fibroid growth rate per year., Tweetable Abstract: Fibroid vascularisation correlates with absolute fibroid volume change and fibroid growth rate per year., (© 2017 Royal College of Obstetricians and Gynaecologists.)- Published

- Abstract
Objectives: To investigate the accuracy and reliability of 3-dimensional (3D) transvaginal sonography in classifying submucous fibroids using the International Federation of Gynecology and Obstetrics PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified) classification and protrusion (percent) compared to 2-dimensional (2D) transvaginal sonography, 2D saline infusion sonography, and 3D saline infusion sonography, using hysteroscopy as a reference test., Methods: A prospective cohort pilot study was performed among 14 consecutive patients undergoing hysteroscopic surgery, preceded by routine sonography (2D transvaginal sonography, 2D saline infusion sonography, 3D transvaginal sonography, and 3D saline infusion sonography)., Results: The intraclass correlation coefficient (ICC) for 2D transvaginal sonography versus hysteroscopy was 0.69 (95% confidence interval [CI], 0.06, 0.90) compared to 0.94 (95% CI, 0.83, 0.98) for 2D saline infusion sonography. The ICCs for 3D transvaginal sonography versus hysteroscopy were 0.69 (95% CI, 0.03, 0.90 [investigator A]) and 0.55 (95% CI, -0.48, 0.86 [investigator B]). The ICCs for 3D saline infusion sonography versus hysteroscopy were 0.94 (95% CI, 0.81, 0.98 [investigator A]) and 0.87 (95% CI, 0.60, 0.96 [investigator B]). Interobserver agreement of 3D transvaginal sonography was 0.81 (95% CI, 0.43, 0.94) compared to 0.86 (95% CI, 0.56, 0.96) for 3D saline infusion sonography., Conclusions: In these preliminary data, 3D transvaginal sonography was not as accurate as 2D or 3D saline infusion sonography and was not more accurate than 2D transvaginal sonography. There was moderate interobserver agreement for 3D transvaginal sonography. There might be room for improvement, as 3D transvaginal sonography is more accurate when endometrial thickness increases. Further study is warranted to evaluate in which patients saline infusion sonography eventually can be obviated., (© 2017 by the American Institute of Ultrasound in Medicine.)

- Abstract
A 32-year-old primigravida presented at our emergency room at 6 weeks of gestation with acute severe right upper quadrant abdominal pain, radiating to the right flank. Vital signs were stable. Abdominal ultrasound showed a round inhomogeneous mass of 10 cm diameter behind the right kidney, suspected for adrenal haemorrhage. The patient was admitted for observation. An MRI showed some right-sided pleural effusion and a round mass in the adrenal region with no recognisable adrenal gland, therefore most likely originating from the right adrenal. After 10 days the patient was discharged with no change in size of the haematoma. MRI was carried out every 2 months which showed a decrease in size of the haematoma, with no other abnormalities. Based on stable MRI and the patient's preference, a vaginal delivery mode was chosen. At 37 weeks of gestation labour was induced, followed by an uncomplicated delivery.

- Abstract
To investigate prospectively the prevalence of high levels of emotional distress and referral rate to psychosocial care in head and neck cancer (HNSCC) patients. Fifty-five consecutive newly diagnosed HNSCC patients were asked to complete the hospital anxiety and depression scale (HADS) and the EORTC QLQ-C30 and H&N35 quality of life questionnaires on a touch screen computer-assisted data collection system on their first visit and during follow-up visit. Sociodemographic, clinical, and quality of life parameters were compared to a high level of distress (HADS score >15). Number of patients with a high level of distress were compared to referral rates to psychosocial care as retrieved from patient hospital files. At time of diagnosis, 18% (10/55) of the patients had a high level of distress (related to tumor stage and site, and global quality of life and social eating) versus 25% (14/55) at follow-up (related to a variety of quality of life parameters). Low levels of distress at baseline or follow-up was noted in 64%; 18% had normal scores at baseline and developed distress at follow-up; 11% had high levels at baseline and returned to normal scores at follow-up, and 7% had persistent distress from baseline to follow-up. No patients were referred to psychosocial care at time of diagnosis. At follow-up visit 21% (3/14) were referred, all patients who developed a high level of distress after initial diagnosis. High level of emotional distress is common and few patients are referred to psychosocial care. Development of a stepped care model (including careful monitoring by using a touch screen computer system) may meet the potentially unmet needs of HNC patients and contribute improving cancer care.

- Abstract
Touch screen computer-assisted health-related quality of life data collection in head and neck cancer patients is feasible. Touch screen computer-assisted health-related quality of life data collection can be used for scientific documentation as well as in clinical setting. Patients are willing to complete the questionnaire on a touch-screen and find the equipment easy to use. Compliance needs improvement by instructing clinicians and nurses and a better alert system.
