Serum erythropoietin level is increased during stimulation for IVF but not in OHSS.

BACKGROUND: Erythropoietin (Epo) is a potent vascular growth factor that induces angiogenesis and antiapoptotic signalling. We investigated whether the development of numerous follicles and corpora lutea during in vitro fertilization (IVF) cycle affects circulating Epo levels and further, if Epo could be used as a novel marker for ovarian hyperstimulation syndrome (OHSS). METHODS: 24 women were included in the uncomplicated IVF group and 35 women in the OHSS group. Repeated blood samples from both groups were analysed for Epo, progesterone, blood haemoglobin, and creatinine. Follicular fluid from the IVF group was analysed for Epo and progesterone. Repeated measure analysis was performed for the variables and circulating Epo levels were compared between the IVF group and early OHSS. Furthermore, related growth factors, vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1 (HIF-1) were analysed from subgroup of women to test for correlation with Epo. RESULTS: During IVF, circulating Epo increased from natural mid-luteal phase to stimulated mid-luteal phase (median 9.5; 95% CI 7.2-13.4 IU/L and 12.5; 10.3-13.4 IU/L; p = 0.003). In cycles resulting in pregnancy, Epo level decreased 14 days after oocyte pick-up (OPU) and remained low thereafter. In cycles not resulting in pregnancy, Epo level increased again 35 days after OPU. Follicle fluid Epo concentration was 1.5 times higher than the serum concentration (median 15.4; 95% CI 10.4-19.2 IU/L vs. 10.2; 8.8-12.7; p = 0.006). There was no difference in circulating Epo concentration between early OHSS and uncomplicated IVF. Circulating Epo did not correlate with VEGF or HIF-1. CONCLUSIONS: Circulating Epo levels fluctuate during IVF cycle. We hypothesise this may suggest Epo's involvement in ovarian physiology and angiogenesis. However, Epo was not a clinical marker for OHSS.

Quality of life and sexual function after tension-free vaginal tape and polyacrylamide hydrogel injection for primary stress urinary incontinence: 3-year follow-up from a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: To assess quality of life (QoL) and sexual function outcomes at 3 years after tension-free vaginal tape (TVT) and polyacrylamide hydrogel injection (PAHG) for stress urinary incontinence (SUI). METHODS: In this randomized trial comparing TVT (n = 104) and PAHG (n = 108), we assessed changes in QoL and sexuality using the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire, Short Form (IIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and RAND-36 Item Health Survey (RAND-36) at baseline and at 3 years. This is a secondary analysis of a randomized, noninferiority trial comparing patient satisfaction after TVT and PAHG. RESULTS: In both groups, incontinence-related QoL improved from the baseline (p < 0.00), except for difficulty emptying the bladder and pain/discomfort. Total scores of UDI-6 and IIIQ-7 were lower for TVT compared to PAHG (p < 0.00) indicating better QoL at 3 years. Urinary incontinence with sexual activity or fear of incontinence restricting sexual activity improved in both groups (p < 0.00), with higher scores for physical section subscale in PISQ-12 (p = 0.02) for TVT. Physical and social functioning (RAND-36) improved from the baseline in both groups (p < 0.01) with a better outcome in the TVT group for physical functioning (p = 0.00). CONCLUSIONS: Both TVT and PAHG improve QoL and sexual function in primary SUI with better incontinence and health-related QoL scores in the TVT group compared to the PAHG group at 3 years.

Association of serum cortisol and cortisone levels and risk of recurrence after endocrine treatment in breast cancer.

Metabolic reprogramming in breast cancer involves changes in steroid hormone synthesis and metabolism. Alterations in estrogen levels in both breast tissue and blood may influence carcinogenesis, breast cancer growth, and response to therapy. Our aim was to examine whether serum steroid hormone concentrations could predict the risk of recurrence and treatment-related fatigue in patients with breast cancer. This study included 66 postmenopausal patients with estrogen receptor-positive breast cancer who underwent surgery, radiotherapy, and adjuvant endocrine treatment. Serum samples were collected at six different time points [before the start of radiotherapy (as baseline), immediately after radiotherapy, and then 3, 6, 12 months, and 7-12 years after radiotherapy]. Serum concentrations of eight steroid hormones (cortisol, cortisone, 17α-hydroxyprogesterone, 17ß-estradiol, estrone, androstenedione, testosterone, and progesterone) were measured using a liquid chromatography-tandem mass spectrometry-based method. Breast cancer recurrence was defined as clinically proven relapse/metastatic breast cancer or breast cancer-related death. Fatigue was assessed with the QLQ-C30 questionnaire. Serum steroid hormone concentrations measured before and immediately after radiotherapy differed between relapse and relapse-free patients [(accuracy 68.1%, p = 0.02, and 63.2%, p = 0.03, respectively, partial least squares discriminant analysis (PLS-DA)]. Baseline cortisol levels were lower in patients who relapsed than in those who did not (p < 0.05). The Kaplan-Meier analysis showed that patients with high baseline concentrations of cortisol (≥ median) had a significantly lower risk of breast cancer recurrence than patients with low cortisol levels (

Sex Steroid Hormone Analysis in Human Tear Fluid Using a Liquid Chromatography-Mass Spectrometry Method.

The marked sexual dimorphism prevalent in inflammatory/autoimmune diseases is mostly due to sex hormone actions. One common eye disease that disproportionately affects women is dry eye. Thus, our aim was to optimise our highly sensitive liquid chromatography-tandem mass spectrometry method for steroid hormone quantification in tear fluid (TF). We used tears and matched serum samples from 10 heathy individuals. Estrone, estradiol testosterone, progesterone, androstenedione, and dehydroepiandrosterone, were quantified with an HPLC coupled with a Triple Quad 5500 MS. Estrone was measured in 80% of female and 20% of male TF samples (mean ± SD, 68.9 ± 62.2 pmol/L), whereas estradiol was undetectable in tears. Progesterone was identified in half of the female tear samples (2.91 ± 3.47 nmol/L) but in none of the male samples, whereas testosterone was quantifiable only in male tears (0.24 ± 0.1 nmol/L). TF hormone levels were, on average, from 1.4% to 55% of systemic values. Estrone, progesterone, and testosterone levels in tears correlated with the matching serum samples (r = 0.82, 0.79, and 0.85, respectively), but androstenedione and dehydroepiandrosterone showed no correlations. Our LC-MS/MS method could detect five out of the six steroid hormones studied in individual human TF samples and could therefore be used to analyse the role of sex steroids in eye diseases.

Tension-Free Vaginal Tape and Polyacrylamide Hydrogel Injection for Primary Stress Urinary Incontinence: 3-Year Followup from a Randomized Clinical Trial.

PURPOSE: We sought to determine whether polyacrylamide hydrogel (PAHG) is noninferior to tension-free vaginal tape (TVT) in the treatment of women with primary stress urinary incontinence (SUI). MATERIALS AND METHODS: In this noninferiority trial, 223 women eligible for operative SUI treatment were randomized for TVT (110) or PAHG (113). Primary outcome was patient satisfaction and the noninferiority margin for the difference was 20%. Secondary outcomes were effectiveness and complications. RESULTS: At 3 years, 188 (84.3%) women attended the followup. The satisfaction score (visual analogue scale 0-100) median was 98.5 (IQR 90-100) in the TVT group and 90.0 (IQR 70-100) in the PAHG group, whereas a score ≥80 was reached in 87 (94.6%) and 65 (67.7%), respectively (difference 26.9%, 95% CI 16.7% to 36.8%). Thus, PAHG did not meet the noninferiority criteria set in our study. The cough stress test was negative in 88 (95.7%) of TVT patients vs 75 (78.1%) of PAHG patients (difference 17.5%, 95% CI 8.6% to 26.9%). Any peri- or postoperative complication before crossover between the groups was detected in 40 (43.5%) women in the TVT group and 23 (24.0%) women in the PAHG group (difference 19.5%, 95% CI 6.8% to 31.4%). CONCLUSIONS: In midterm followup, PAHG did not reach in patient satisfaction the noninferiority set in our study. Furthermore, mid urethral TVT slings show better subjective and objective cure rates than PAHG. However, complications were more often associated with TVT. Since the majority of PAHG treated women were also cured or improved, primary SUI women can be offered PAHG as a safe and durable alternative treatment.

Maternal childbirth experience and induction of labour in each mode of delivery: a retrospective seven-year cohort study of 95,051 parturients in Finland.

BACKGROUND: Childbirth experience has been shown to depend on the mode of delivery. However, it is unclear how labour induction influences the childbirth experience in different modes of delivery. Thus, we assessed the childbirth experience among mothers with spontaneous and induced labours. DESIGN: A retrospective cohort study. SETTING: Childbirths in four delivery hospitals in Helsinki and Uusimaa District, Finland, in 2012-2018. SAMPLE: 95051 childbirths excluding elective caesarean sections. METHODS: Obstetric data combined to maternal childbirth experience measured by Visual Analogue Scale (VAS) was analysed with univariate linear modelling and group comparisons. The primiparas and multiparas were analysed separately throughout the study due to the different levels of VAS. MAIN OUTCOME MEASURES: Maternal childbirth experience measured by VAS. RESULTS: The negative effect of labour induction on the childbirth experience was discovered in each mode of delivery. Operative deliveries were perceived more negatively when they were preceded by labour induction. The rate of poor childbirth experience (VAS≤5) was higher for mothers with labour induction (ORs varying from 1.43 to 1.77) except in emergency caesarean sections. The negative effect of labour induction was smaller than the effect of mode of delivery, while successful vaginal delivery with induction (meanPRIMI=8.00 [95% CI 7.96-8.04], meanMULTI=8.50 [8.47-8.53]) was perceived more positive than operational deliveries with spontaneous labour (meansPRIMI≤7.66 [7.61-7.70], meansMULTI≤7.96 [7.89-8.03]). However, labour induction more than doubled the risk of caesarean section for both primiparas and multiparas. CONCLUSIONS: Labour induction generates more negative experiences for both primiparas and multiparas. The negative effect of labour induction is detected for all modes of delivery, being worst among labour induction resulting in operative delivery. The parturients facing cumulative obstetric interventions require special support and counselling during and after delivery.

Direct Ink Writing of Biocompatible Nanocellulose and Chitosan Hydrogels for Implant Mesh Matrices.

Direct ink writing via single or multihead extrusion is used to synthesize layer-by-layer (LbL) meshes comprising renewable polysaccharides. The best mechanical performance (683 ± 63 MPa modulus and 2.5 ± 0.4 MPa tensile strength) is observed for 3D printed structures with full infill density, given the role of electrostatic complexation between the oppositely charged components (chitosan and cellulose nanofibrils). The LbL structures develop an unexpectedly high wet stability that undergoes gradual weight loss at neutral and slightly acidic pH. The excellent biocompatibility and noncytotoxicity toward human monocyte/macrophages and controllable shrinkage upon solvent exchange make the cellular meshes appropriate for use as biomedical implants.

Adipose tissue estrogen production and metabolism in premenopausal women.

OBJECTIVE: Although the ovaries produce the majority of estrogens in women before menopause, estrogen is also synthesized in peripheral tissues such as adipose tissue (AT). The typical female AT distribution, concentrated in subcutaneous and femoro-gluteal regions, is estrogen-mediated, but the significance of estrogen synthesis in AT of premenopausal women is poorly understood. DESIGN AND METHODS: Serum and subcutaneous and visceral AT homogenates from 28 premenopausal women undergoing non-malignant surgery were analyzed for estrone, estradiol, and serum estrone sulfate (E1S) concentrations with liquid chromatography-tandem mass spectrometry. Isotopic precursors were used to measure enzyme activities of estrone-producing steroid sulfatase and estradiol-producing 17ß-hydroxysteroid dehydrogenases (17ß-HSD). Messenger RNA (mRNA) expression levels of genes for estrogen-metabolizing enzymes were analyzed using real-time reverse transcription quantitative polymerase chain reaction. RESULTS: While estradiol was the predominant circulating active estrogen, estrone dominated in AT, with a higher concentration in visceral than subcutaneous AT (median, 2657 vs 1459 pmol/kg; P = 0.002). Both AT depots converted circulating E1S to estrone, and estrone to estradiol. Median levels of estrone were five to ten times higher in subcutaneous and visceral AT than in serum (P < 0.001) and the estradiol level in visceral AT was 1.3 times higher than in serum (P < 0.005). The local estrone concentration in visceral AT correlated positively with mRNA expression of estrone-producing enzyme aromatase (r = 0.65, P = 0.003). Waist circumference correlated positively with increased estradiol production in subcutaneous AT (r = 0.60, P = 0.039). CONCLUSIONS: Premenopausal AT demonstrated high estrogenic enzyme activity and considerable local estrogen concentrations. This may be a factor promoting female-typical AT distribution in premenopausal women.

Pregnancy and delivery after mid-urethral sling operation.

INTRODUCTION AND HYPOTHESES: There is no consensus regarding pregnancy after mid-urethral sling (MUS) operation, and some clinicians recommend postponing the MUS operation if a woman considers further pregnancies or routinely suggest cesarean section as the delivery method after MUS operations. Our primary aim was to assess the risk for stress urinary incontinence (SUI) re-procedure after delivery in women with a MUS operation prior to pregnancy. We also analyzed SUI re-visits and MUS-related complications during pregnancy and postpartum. METHODS: We conducted a register-based case-control study of women with a MUS operation in Finland during 1996-2016. We identified 94 cases with a subsequent pregnancy and 330 controls without subsequent pregnancies matched by age, operation type and year. RESULTS: The median follow-up time was 10.7 years (IQR 7.1-13.7). The number of SUI re-procedures did not differ between the cases (n = 3, 3.2%) and controls (n = 17, 5.2%; OR 0.6, 95% CI 0.2-2.1). There was no significant difference in re-visits for stress or mixed urinary incontinence between the cases (n = 23, 24.5%) and controls (n = 86, 26.1%; OR 0.9, 95% CI 0.5-1.6), but 35% of the re-visits in the case group occurred already before the delivery after MUS. The rate of vaginal delivery was lower after MUS operation (57%) than in deliveries before MUS (91%, P < 0.001). CONCLUSIONS: Pregnancy after MUS did not increase the odds for SUI re-procedure or re-visit. Considering on our results, future pregnancy does not need to be viewed as an absolute contraindication for MUS operation.

Quality of life and sexual function after TVT surgery versus Bulkamid injection for primary stress urinary incontinence: 1 year results from a randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: To assess changes in quality of life (QoL) and sexual function outcomes at 1 year after tension-free vaginal tape (TVT) versus polyacrylamide hydrogel injection (PAHG). METHODS: In a randomized trial comparing TVT (n = 111) and PAHG (n = 113) treatments of stress urinary incontinence (SUI), we compared urinary incontinence and health-related QoL using the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire, Short Form (IIQ-7), Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and RAND-36 Item Health Survey (RAND-36) at baseline and 1 year. RESULTS: UDI-6 and IIQ-7 showed improved incontinence-related QoL (p = 0.001) from baseline in both groups except for difficulty emptying the bladder and pain/discomfort. At 1 year, TVT patients experienced less urinary symptom-related distress compared to PAHG (p < 0.001). Sexual function improved in both groups (p < 0.001 for TVT and p = 0.01 for PAHG) with higher scores for the physical section subscale (p < 0.001) for TVT. Health-related QoL (RAND-36) improved from baseline in both groups in physical and social functioning (p < 0.001) with better outcome in the TVT group for physical functioning (p < 0.001). Increase in pain from baseline (p = 0.02) was detected for TVT, but not for PAHG. However, there was no difference between the groups (p = 0.78). CONCLUSIONS: In primary SUI, TVT and PAHG treatments both improved QoL and sexual function at 1 year. However, incontinence and health-related QoL scores were better in the TVT group. More pain compared to the baseline was reported after TVT, although there was no difference between groups. Clinical significance needs to be evaluated in long-term follow-up.

Human adipocyte differentiation and composition of disease-relevant lipids are regulated by miR-221-3p.

MicroRNA-221-3p (miR-221-3p) is associated with both metabolic diseases and cancers. However, its role in terminal adipocyte differentiation and lipid metabolism are uncharacterized. miR-221-3p or its inhibitor was transfected into differentiating or mature human adipocytes. Triglyceride (TG) content and adipogenic gene expression were monitored, global lipidome analysis was carried out, and mechanisms underlying the effects of miR-221-3p were investigated. Finally, cross-talk between miR-221-3p expressing adipocytes and MCF-7 breast carcinoma (BC) cells was studied, and miR-221-3p expression in tumor-proximal adipose biopsies from BC patients analyzed. miR-221-3p overexpression inhibited terminal differentiation of adipocytes, as judged from reduced TG storage and gene expression of the adipogenic markers SCD1, GLUT4, FAS, DGAT1/2, AP2, ATGL and AdipoQ, whereas the miR-221-3p inhibitor increased TG storage. Knockdown of the predicted miR-221-3p target, 14-3-3γ, had similar antiadipogenic effects as miR-221-3p overexpression, indicating it as a potential mediator of mir-221-3p function. Importantly, miR-221-3p overexpression inhibited de novo lipogenesis but increased the concentrations of ceramides and sphingomyelins, while reducing diacylglycerols, concomitant with suppression of sphingomyelin phosphodiesterase, ATP citrate lyase, and acid ceramidase. miR-221-3p expression was elevated in tumor proximal adipose tissue from patients with invasive BC. Conditioned medium of miR-221-3p overexpressing adipocytes stimulated the invasion and proliferation of BC cells, while medium of the BC cells enhanced miR-221-3p expression in adipocytes. Elevated miR-221-3p impairs adipocyte lipid storage and differentiation, and modifies their ceramide, sphingomyelin, and diacylglycerol content. These alterations are relevant for metabolic diseases but may also affect cancer progression.

Long-term re-procedure rate after mid-urethral slings for stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: Long-term safety concerns have risen over the mid-urethral sling operation (MUS) for stress urinary incontinence (SUI), which in some countries has led to litigations and even suspending MUS insertions. We examined the long-term re-procedure rate after MUS operations. The main outcome was re-procedures for SUI. The secondary outcome was surgical interventions due to complications. METHODS: We analysed a retrospective population cohort of 3531 women with MUS operations in 2000-2006 and followed them up until 31 December 2016. Data were collected from a national hospital register and from hospital patient records. RESULTS: The median follow-up time was 13 years (IQR 11.6-14.8) for the 3280 women with a retropubic MUS (RP-MUS) and 11 years (IQR 10.3-11.9) for the 245 women with a transobturator MUS (TO-MUS). The cumulative number of re-procedures for SUI was 16 (0.5%) at 1 year, 66 (1.9%) at 5 years, 97 (2.8%) at 10 years and 112 (3.2%) at 17 years. This risk was higher after TO-MUS than after RP-MUS operations (OR 3.6, 95% CI 2.5-5.2, p < 0.001). The cumulative number of any long-term re-procedure was 43 (1.2%) at year 1, 105 (3.0%) at year 5, 144 (4.1%) at year 10 and 163 (4.6%) at year 17. CONCLUSIONS: Re-procedures occur up to 17 years after primary MUS insertion, but their incidence is low after the first few postoperative years. Re-procedures for recurrent SUI are more common after TO-MUS than RP-MUS.

Tension-Free Vaginal Tape Surgery versus Polyacrylamide Hydrogel Injection for Primary Stress Urinary Incontinence: A Randomized Clinical Trial.

PURPOSE: We evaluated whether polyacrylamide hydrogel is noninferior to tension-free vaginal tape to treat women with primary stress urinary incontinence. MATERIALS AND METHODS: In this controlled noninferiority clinical trial patients with primary stress urinary incontinence were randomized to tension-free vaginal tape or polyacrylamide hydrogel treatment. The primary outcome was patient satisfaction and secondary outcomes were effectiveness in reducing urinary leakage and complications at 1-year followup. For statistical power significance was considered at 5%, power was set at 80% and the noninferiority limit was 20% with a 10% expected dropout rate. RESULTS: A total of 224 women with primary stress urinary incontinence entered the study between September 28, 2015 and March 1, 2017. Of the women 111 were randomized to tension-free vaginal tape and 113 were randomized to polyacrylamide hydrogel. At 1 year a satisfaction score of 80 or greater on a visual analogue scale of 0 to 100 was reached in 95.0% and 59.8% of patients treated with tension-free vaginal tape and polyacrylamide hydrogel, respectively. Thus, polyacrylamide hydrogel did not meet the noninferiority criteria set in our study. As secondary outcomes, the cough stress test was negative in 95.0% of tension-free vaginal tape cases vs 66.4% of polyacrylamide hydrogel cases (difference 28.6%, 95% CI 18.4-38.5). However, most perioperative complications, including those in 19 tension-free vaginal tape cases vs 3 polyacrylamide hydrogel cases (difference 16.0%, 95% CI 7.8-24.9), and all 6 reoperations due to complications (difference 5.9%, 95% CI 1.2-12.4) were associated with tension-free vaginal tape. CONCLUSIONS: Mid urethral tension-free vaginal tape slings were associated with better satisfaction and cure rates than polyacrylamide hydrogel in women with primary stress urinary incontinence. However, complications were mainly associated with tension-free vaginal tape. Thus, tension-free vaginal tape should be offered as first line treatment in women who expect to be completely cured by the initial treatment and are willing to accept the complication risks. Since polyacrylamide hydrogel treatment also provides high satisfaction and cure rates, women with primary stress urinary incontinence can be offered polyacrylamide hydrogel as an alternative treatment.

Simulator training and residents' first laparoscopic hysterectomy: a randomized controlled trial.

BACKGROUND: Hysterectomy rates are decreasing in many countries, and virtual reality simulators bring new opportunities into residents' surgical education. The objective of this study was to evaluate the effect of training in laparoscopic hysterectomy module with virtual reality simulator on surgical outcomes among residents performing their first laparoscopic hysterectomy. METHODS: This randomized study was carried out at the Department of Obstetrics and Gynecology in Helsinki University Hospital and Hyvinkää Hospital. We recruited twenty residents and randomly signed half of them to train ten times with the laparoscopic hysterectomy module on a virtual reality simulator, while the rest represented the control group. Their first laparoscopic hysterectomy was video recorded and assessed later by using the Objective Structured Assessment of Technical Skills (OSATS) forms and Visual Analog Scale (VAS). The scores and surgical outcomes were compared between the groups. RESULTS: The mean OSATS score for the Global Rating Scale (GRS) was 17.0 (SD 3.1) in the intervention group and 11.2 (SD 2.4) in the control group (p = 0.002). The mean procedure-specific OSATS score was 20.0 (SD 3.3) and 16.0 (SD 2.8) (p = 0.012), and the mean VAS score was 55.0 (SD 14.8) and 29.9 (SD 14.9) (p = 0.001). Operative time was 144 min in the intervention group and 165 min in the control group, but the difference did not reach statistical significance (p = 0.205). There were no differences between the groups in blood loss or direct complications. CONCLUSION: Residents training with a virtual reality simulator prior to the first laparoscopic hysterectomy seem to perform better in the actual live operation. Thus, a virtual reality simulator hysterectomy module could be considered as a part of laparoscopic training curriculum.

Patient utilization survey of mirabegron prescribed for overactive bladder.

Purpose: Mirabegron, a ß3-adrenoreceptor agonist, is used to treat overactive bladder. The factors affecting persistence of mirabegron use or symptom improvement are not thoroughly known, but could be related to patient characteristics. Therefore, we evaluated persistence of medication use, symptom improvement, and quality of life among Finnish mirabegron users. In addition, we assessed possible predictors of change in these variables. Materials and Methods: Participants (52 men, 118 women) with an initial mirabegron prescription were recruited nationwide from 79 pharmacies. Volunteers were interviewed at baseline and after 6 months. Subject and clinical characteristics, symptom severity, and quality of life (EQ-5D-5L) were assessed using a visual analogue scale. Results: Of 170 participants, 144 (84.7%) were reached after 6 months. The rate of persistent mirabegron use was 50.7%. Experiencing adverse effects (29.6%) was the most common reason for discontinuation of medication. A primary health care unit as a prescription site (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.03-4.9) was associated with increased risk for discontinuation. Mirabegron relieved symptoms in 45.2% and enhanced quality of life in 41.7% of the participants. Age <64 years was associated with better probability of symptom improvement (OR, 2.7; 95% CI, 1.1-6.8), whereas none of the other parameters assessed predicted change in quality of life. Conclusions: In this Finnish population, 50.7% of the participants continued using mirabegron after 6 months. The prescription site seemed to be important for persistent use, which may be related to patient counseling. Younger patients were more likely to benefit from treatment with mirabegron.

Use of postmenopausal hormone therapy and risk of Alzheimer's disease in Finland: nationwide case-control study.

OBJECTIVES: To compare the use of hormone therapy between Finnish postmenopausal women with and without a diagnosis for Alzheimer's disease. DESIGN: Nationwide case-control study. SETTING: Finnish national population and drug register, between 1999 and 2013. PARTICIPANTS: All postmenopausal women (n=84 739) in Finland who, between 1999 and 2013, received a diagnosis of Alzheimer's disease from a neurologist or geriatrician, and who were identified from a national drug register. Control women without a diagnosis (n=84 739), matched by age and hospital district, were traced from the Finnish national population register. INTERVENTIONS: Data on hormone therapy use were obtained from the Finnish national drug reimbursement register. MAIN OUTCOME MEASURES: Odds ratios and 95% confidence intervals for Alzheimer's disease, calculated with conditional logistic regression analysis. RESULTS: In 83 688 (98.8%) women, a diagnosis for Alzheimer's disease was made at the age of 60 years or older, and 47 239 (55.7%) women had been over 80 years of age at diagnosis. Use of systemic hormone therapy was associated with a 9-17% increased risk of Alzheimer's disease. The risk of the disease did not differ significantly between users of estradiol only (odds ratio 1.09, 95% confidence interval 1.05 to 1.14) and those of oestrogen-progestogen (1.17, 1.13 to 1.21). The risk increases in users of oestrogen-progestogen therapy were not related to different progestogens (norethisterone acetate, medroxyprogesterone acetate, or other progestogens); but in women younger than 60 at hormone therapy initiation, these risk increases were associated with hormone therapy exposure over 10 years. Furthermore, the age at initiation of systemic hormone therapy was not a decisive determinant for the increase in risk of Alzheimer's disease. The exclusive use of vaginal estradiol did not affect the risk of the disease (0.99, 0.96 to 1.01). CONCLUSIONS: Long term use of systemic hormone therapy might be accompanied with an overall increased risk of Alzheimer's disease, which is not related to the type of progestogen or the age at initiation of systemic hormone therapy. By contrast, use of vaginal estradiol shows no such risk. Even though the absolute risk increase for Alzheimer's disease is small, our data should be implemented into information for present and future users of hormone therapy.

Comparison of two retropubic tension-free vaginal tape procedures in women with stress urinary incontinence: a randomized controlled multicenter trial.

PURPOSE: Midurethral slings are a well-established treatment option in women suffering stress urinary incontinence. Various different products and methods are used, therefore, the aim of our study was to compare two inside-out retropubic slings (TVT exact® vs. RetroArc®) inserted in two different ways regarding perioperative and mid-term outcomes. METHODS: In this prospective randomized controlled non-inferiority multicentre trial, primary endpoint was postoperative cure rate, both objective (negative cough test) and subjective (absence of leakage during physical activity using the UDI-6 questionnaire). Secondary endpoints were patients' satisfaction (Likert scale; ICIQ-UI-SF questionnaires). In addition, intra-and postoperative complications were evaluated. The TVT®-group was operated with an empty bladder, a 18 CH catheter was used with a straight inserter as instructed. Patients randomized into the RetroArc®-group were operated without inserter leading to a reduced catheter size (14 CH), bladder was filled (200 ml) during the procedure. RESULTS: Of the 303 women, 152 were randomized to the TVT® and 151 to the RetroArc® operation. At 3 months, n = 288 (95.0%) and at 12 months n = 229 (75.6%) were assessed. In postoperative objective cure the RetroArc®-procedure was not inferior to TVT® (p = 0.144). In subjective cure, however, the TVT exact® procedure achieved significant better results (TVT® 76.1%, RetroArc® 54.3%, p = 0.002). Perioperative complications were in majority voiding difficulties and lower after the TVT exact®-procedure. CONCLUSIONS: Retropubic sling procedures are safe and successful to treat female stress urinary incontinence. However, different materials and techniques result in differences between outcomes also experienced surgeons should be aware of.

Effect of structural training on surgical outcomes of residents' first operative laparoscopy: a randomized controlled trial.

BACKGROUND: Gynecological surgery and resident education have changed during recent decades, thus impacting surgical training. Training on simulators must begin before operating on patients. The objective of this study was to evaluate the effect of a simple curriculum on the surgical outcome of the participants' first operative laparoscopy. METHODS: This randomized prospective interventional study was carried out in Helsinki University Hospital and Hyvinkää Hospital. We recruited twenty junior residents in Obstetrics and Gynecology, of which half formed a control group and the rest completed the intervention with a theoretical and a practical part. The participants' first laparoscopic salpingectomy was assessed from video recordings by using Objective Structured Assessment of Technical Skills (OSATS) forms and the Numeric Rating Scale (NRS). The surgical outcome and assessed scores were compared between the groups. RESULTS: We found no differences in operative time, blood loss, or complications, nor in OSATS or NRS scores. In the intervention group, participants with the weakest performances in the simulator, seemed to benefit from the training program more than the participants with the best performances (skill level elevation 29.2-31.6% vs. 21.1-23.3%, respectively). The participants with the best performances in the simulator were scored among the best in the recorded operations as well. CONCLUSION: In this study, we found no difference in the surgical outcome between the groups. However, the participants with low starting levels in the simulator could elevate their skill levels more, though they did not reach the skill level of those with a high starting level. Consequently, we found elevation in skills levels in the simulator tasks, but not in the surgical outcome. Likely, our simple training program with a fixed number of repetitions was insufficient to reach a plateau in the learning curve, and thus the training program in such a curriculum should be proficiency based.

Pelvic Organ Prolapse Repair Using the Uphold Vaginal Support System: 5-Year Follow-Up.

OBJECTIVE: This study aimed to assess the long-term (5 years) outcomes of the Uphold Vaginal Support System for symptomatic vaginal apical prolapse with or without anterior colporraphy. METHODS: In total, 164 (81.2%) of 202 women operated on in 24 centers were reached for follow-up. Outcomes were assessed by using the Pelvic Organ Prolapse Quantification, the Pelvic Floor Distress Inventory 20, and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire questionnaires. Pain on pelvic area was evaluated using a visual analog scale. Adverse events and secondary procedures were recorded. RESULTS: An optimal outcome at the apical compartment (Pelvic Organ Prolapse Quantification stage <2) was achieved in 83.3% of patients (94% at 1 year). Quality of life improved in 78.8% of the women, with a significant decrease of bother in all domains (pelvic organ prolapse, rectoanal, urinary) compared with that preoperatively. Overall sexual satisfaction improved after 1 year, but the number of sexually active women was low. In total, 19.7% of patients had undergone repeat pelvic surgery during follow-up, most common of these were midurethral sling (38.4%), followed by prolapse-related operations. Mesh removal due to pain was performed in 3 women. Number of women with any pain decreased overall from 1 to 5 years, but 3 women had persistent severe pain despite treatment efforts (visual analog scale ≥7). CONCLUSIONS: Apical objective and subjective outcomes were sustained after 5 years in women operated on for apical compartment prolapse by the Uphold Vaginal Support System.
