Intermediate- to long-term outcomes of transvaginal mesh for treatment of Asian women with pelvic organ prolapse.

INTRODUCTION: Short-term follow-up analyses suggest that transvaginal mesh has limited application for pelvic organ prolapse (POP) treatment. This study evaluated the intermediate- and long-term outcomes of transvaginal mesh surgery. METHODS: This retrospective study included all women who underwent transvaginal mesh surgery in one urogynaecology centre. Inclusion criteria were women with stage III/IV POP, age ≥65 years, and (preferably) sexual inactivity. Concomitant sacrospinous fixation and mid-urethral slings were offered for stage III/IV apical POP and urodynamic stress incontinence, respectively. Women were followed up for 5 years. Subjective recurrence was defined as reported prolapse symptoms. Objective recurrence was defined as stage II prolapse or above. Mesh complications and patient satisfaction were reviewed. RESULTS: Of 183 women who underwent transvaginal mesh surgery, 156 had ≥1 year of follow-up (mean, 50 ± 22 months). Subjective and objective recurrence rates were 5.1% and 10.9%, respectively. The mesh erosion rate was 9.6%; all affected women received local oestrogen treatment or bedside surgical excision. Three women received transobturator tension-free transvaginal tape for de novo (n=1) or preoperative urodynamic stress incontinence who did not undergo concomitant surgery (n=2); 14% of the women had de novo urgency urinary incontinence. No women reported chronic pain. Overall, 98% were 'satisfied' or 'very satisfied' with the operation. CONCLUSION: During 50 months of follow-up, transvaginal mesh surgery for stage III/IV POP had low subjective and objective recurrence rates. The total re-operation rate was 9.6%. Most women were satisfied with the operation. Based on the risk-benefit profile, transvaginal mesh surgery may be suitable for women who have advanced POP.

Discrepancies between actual weight, weight perception and weight loss intention amongst persons with NAFLD.

BACKGROUND: Currently, weight loss remains the main management strategy for NAFLD, but the weight loss intention and methods remain poorly characterized. METHODS: We analysed data about the perception of weight status, intention and methods to lose weight amongst 3,822 persons with NAFLD (United States Fatty Liver Index ≥ 30) from the National Health and Nutrition Examination Survey, 2001-2014. RESULTS: Only 53.9% of people with NAFLD intended to lose weight, 91.8% with perception of overweight and 8.2% with normal weight perception. Persons with perception of overweight or overweight/obese status were four times more likely to try to lose weight (adjusted odds ratios 3.9 and 4.2, respectively, both P < 0.0001). Younger age, women, higher educational level, Hispanic and blacks (versus whites) were significant independent factors associated with weight loss intention. Notably, ≤10% attended weight loss programme. Metabolic equivalent of task hours per week was significantly higher in whites who exercised to lose weight (vs. no exercise, P = 0.003) but not in other racial/ethnic groups. Interestingly, calorie intake was similar between those who dieted versus not (2056 vs. 1970 kcal/day, P = 0.11). About 30% reported ≥ 10-lb weight loss, with 50% higher odds of success for men but there was no difference by race/ethnicity. CONCLUSION: Overweight or obese perception was a key driver in weight loss activities but was inconsistent with actual weight status and varied by race/ethnicity and other sociodemographic factors. Weight loss programme is under-utilized and should take in account of weight perception training and culturally appropriate approach.

Women with advanced pelvic organ prolapse and levator ani muscle avulsion would significantly benefit from mesh repair surgery.

OBJECTIVES: Mesh repair surgery for pelvic organ prolapse (POP) has been suspended in some countries owing to concerns about its associated complications. However, mesh repair has been shown to reduce the risk of prolapse recurrence after surgery. In view of this controversy, our aim was to assess the incidence of subjective and objective recurrence of POP following mesh repair surgery vs native-tissue repair in women with Stage-III or Stage-IV POP. METHODS: This was a prospective observational study of women who presented with Stage-III or Stage-IV POP and received primary prolapse surgery between 2013 and 2018. Transperineal ultrasound was performed before the operation and volumes were analyzed offline to assess the presence of levator ani muscle (LAM) avulsion. All women were counseled on either mesh repair or native-tissue reconstruction. The mesh-repair group was followed up for up to 5 years and the native-tissue-repair group for up to 2 years after the operation. Prolapse symptoms and POP quantification (POP-Q) staging were assessed at follow-up. Subjective recurrence of POP was defined as symptoms of prolapse (vaginal bulge sensation or dragging sensation) reported by the patient. Objective recurrence was defined as POP-Q ≥ Stage II. The subjective and objective recurrences of prolapse were compared between women with and those without mesh use. Multivariate regression analysis was used to identify risk factors for the recurrence of POP. RESULTS: A total of 154 Chinese women with Stage-III or Stage-IV prolapse were recruited. Of these, 104 (67.5%) underwent mesh repair (transabdominal in 57 women and transvaginal in 47 women) and 50 (32.5%) had native-tissue repair surgery. Ninety-five (61.7%) women had LAM avulsion. Both the subjective POP recurrence rate (4.8% vs 20.0%; P = 0.003) and the objective recurrence rate (20.2% vs 46.0%; P = 0.001) were significantly lower in the mesh-repair group than in the native-tissue-repair group. On multivariate logistic regression analysis, mesh repair was associated significantly with a reduced risk of subjective recurrence (odds ratio (OR), 0.20 (95% CI, 0.07-0.63)) and of objective recurrence (OR, 0.16 (95% CI, 0.07-0.55)) of prolapse. On subgroup analysis of women with LAM avulsion, mesh repair significantly reduced the risk of subjective recurrence (OR, 0.24 (95% CI, 0.07-0.87)) and objective recurrence (OR, 0.23 (95% CI, 0.09-0.57)) of POP. The incidence of mesh-related complications was low, and mesh exposure could be treated conservatively or by minor surgery. CONCLUSIONS: Mesh repair surgery, compared with native-tissue repair, was associated with a 5-fold reduction in the risk of subjective recurrence and a 6-fold reduction in the risk of objective recurrence of prolapse in women with Stage-III or Stage-IV POP. In women with concomitant LAM avulsion, mesh repair surgery was associated with a 4-fold reduction in both objective and subjective recurrence of POP. The rate of mesh-related complications was low, and mesh exposure could be treated conservatively or by minor surgery. The benefit of mesh surgery for these high-risk women appears to outweigh the risks of mesh complications, and it could be a treatment option for this group of women. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

2020 Hong Kong College of Obstetricians and Gynaecologists guideline on investigations of premenopausal women with abnormal uterine bleeding.

Abnormal uterine bleeding in premenopausal women is a common gynaecological symptom and composes of abnormality in the frequency, duration, regularity, and flow volume of menstruation. It could constitute the presentation of various gynaecological malignancies. An appropriate history and physical examination are mandatory to ascertain the diagnosis. Depending on the clinical condition, a complete blood picture, thyroid function test, clotting profile, chlamydia test, cervical smear, and pregnancy test can be performed. Ultrasound should be performed in cases with a pelvic mass, unsatisfactory physical examination, persistent symptoms, or no response to medical treatment. In women aged ≥40 years, an out-patient endometrial biopsy with Pipelle should be performed. In women aged <40 years with risk factors for endometrial cancer, persistent symptoms, or no response to medical treatment, an endometrial biopsy should be performed to rule out endometrial cancer. Hysteroscopy or saline infusion sonohysterography is more sensitive than ultrasound for diagnosing endometrial pathology. Details of the above recommendations are presented.

Prevalence, characteristics and mortality outcomes of obese, nonobese and lean NAFLD in the United States, 1999-2016.

BACKGROUND: Updated prevalence and outcome data for nonobese NAFLD for the multi-ethnic US population is limited. OBJECTIVES: We aimed to investigate the prevalence, clinical characteristics and mortality of obese and nonobese individuals with NAFLD in the United Sates. METHODS: A retrospective study was conducted using the 1999-2016 NHANES databases. We determined hazard ratio stratified by obesity status in NAFLD individuals using Cox regression and log-rank test. RESULTS: Overall NAFLD prevalence was 32.3%: 22.7% were obese and 9.6% were nonobese, with increasing trend over time for obese NAFLD, but not nonobese NAFLD. Amongst those with NAFLD, 29.7% (95% CI: 27.8%-31.7%) were nonobese, of which 13.6% had lean NAFLD. Nonobese NAFLD was more common in older (40.9% if ≥ 65 vs. 24.2% if < 65 years), male (34.0% vs. 24.2%) and foreign-born Asian people (39.8% vs. 11.4%) and uncommon in black (11.5% vs 30-35% in other ethnicities, P < 0.001). Metabolic comorbidities were common in nonobese NAFLD individuals who also had more advanced fibrosis. Nonobese NAFLD individuals had higher 15-year cumulative all-cause mortality (51.7%) than obese NAFLD (27.2%) and non-NAFLD (20.7%) (P < 0.001). However, DM and fibrosis, but neither obese nor nonobese NAFLD compared to non-NAFLD was independently associated with higher mortality. CONCLUSION: Nonobese NAFLD makes up about one-third of the NAFLD in the United States (even higher in older, male and foreign-born individuals) and carries higher mortality than obese NAFLD. Screening for NAFLD should be considered in high-risk groups even in the absence of obesity.

Ethnic influence on nonalcoholic fatty liver disease prevalence and lack of disease awareness in the United States, 2011-2016.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a rising global disease associated with clinical and economic burdens. OBJECTIVES: We aimed to quantify NAFLD prevalence and awareness to provide stakeholders necessary information to combat NAFLD burden. METHODS: This study utilizes data from the National Health and Nutrition Examination Survey 2011-2016 and included 4538 adult participants who did not have heavy drinking or viral hepatitis history. The US fatty liver index defined NAFLD and NAFLD fibrosis score defined fibrosis. NAFLD awareness was captured by questionnaire. RESULTS: Amongst the study population of 4538 persons, NAFLD prevalence was 32.5%, lowest in non-Hispanic Blacks (18.0%) and Asians (18.1%), highest amongst Mexican Americans (48.4%). Within the NAFLD group, advanced fibrosis was highest in non-Hispanic Blacks (28.5%) and lowest amongst non-Hispanic Asians (2.7%). Of the 1473 (97.5%) NAFLD participants who answered NAFLD awareness question, 90% visited a healthcare centre at least once in the past year, but only 5.1% were aware of having NAFLD. On weighted population estimates, 77.33 million persons had NAFLD, 17.63 million had advanced fibrosis, and 73.39 million NAFLD participants were not aware of having NAFLD. CONCLUSIONS: Of 77.33 million people in the United States have NAFLD with 17.63 million having advanced fibrosis, with lowest prevalence in non-Hispanic Asians and highest in Mexican Americans. A conundrum exists amongst non-Hispanic Blacks who have low NAFLD prevalence but highest prevalence of advanced fibrosis. Awareness of NAFLD was low across all ethnicities. Effort is needed to improve disease awareness whilst addressing NAFLD clinical burden across ethnicities.

Prevalence of obstetric anal sphincter injury following vaginal delivery in primiparous women: a retrospective analysis.

INTRODUCTION: Obstetric anal sphincter injuries (OASIS) may be underdetected in primiparous women. This study evaluated the prevalence of OASIS in primiparous women after normal vaginal delivery or instrumental delivery using endoanal ultrasound (US) during postnatal follow-up. METHODS: This study retrospectively analysed endoanal US data collected during postnatal follow-up (6-12 months after vaginal delivery) at a tertiary hospital in Hong Kong. Offline analysis to determine the prevalence of OASIS was performed by two researchers who were blinded to the clinical diagnosis. Symptoms of faecal and flatal incontinence were assessed with the Pelvic Floor Distress Inventory. RESULTS: Of 542 women included in the study, 205 had normal vaginal delivery and 337 had instrumental delivery. The prevalence of OASIS detected by endoanal US was 7.8% (95% confidence interval [CI]=4.1%-11.5%) in the normal vaginal delivery group and 5.6% (95% CI=3.1%-8.1%) in the instrumental delivery group. Overall, 82.9% of women with OASIS on endoanal US did not show clinical signs of OASIS. Birth weight was significantly higher in the OASIS group (P=0.012). At 6 to 12 months after delivery, 5.5% of women reported faecal incontinence and 17.9% reported flatal incontinence, but OASIS was not associated with these symptoms. CONCLUSIONS: Additional training for midwives and doctors may improve OASIS detection.

Decreased tibial nerve movement in patients with failed back surgery syndrome and persistent leg pain.

PURPOSE: To measure and compare the total and normalised tibial nerve movements during forward bending in patients with and without failed back surgery syndrome (FBSS) and persistent leg pain following anatomically successful lumbar decompression surgery and demonstrated no psychological stress. Nerve pathomechanics may contribute to FBSS with persistent leg pain following anatomically successful lumbar decompression surgery. METHODS: Tibial nerve movement during forward bending was measured in two groups of patients following anatomically successful lumbar decompression surgery. FBSS group (N = 37) consisted of patients with persistent leg pain following lumbar surgery, and non-FBSS (N = 37) were patients with no remaining leg pain following lumbar surgery. Total and normalised tibial nerve movement at the popliteal fossa was measured by a previously validated ultrasound imaging technique and compared between the two groups, and also between the painful and non-painful leg within the FBSS group. RESULTS: Both the mean total and normalised tibial nerve movement were significantly decreased in the FBSS group in both legs when compared to the non-FBSS group (P < 0.05). The total and normalised tibial nerve movements were also more restricted in the painful leg (P < 0.05) when compared to the non-painful side within the FBSS group. CONCLUSION: This was the first study to quantify the decreased total and normalised tibial nerve mobility in FBSS patients with persistent leg pain when compared with non-FBSS patients following anatomically successful lumbar decompression surgery. Further research could investigate the efficacy of intervention, such as nerve mobilisation in this particular group of patients with failed back surgery syndrome and limited nerve mobility.

Pelvic organ prolapse in Caucasian and East Asian women: a comparative study.

OBJECTIVE: Ethnicity has been suggested to be a significant risk factor for pelvic organ prolapse (POP); yet, pelvic organ descent in different ethnic groups, especially in Asian populations, is not well studied. The aim of this study was to compare prolapse stages, pelvic organ descent and hiatal dimensions between East Asian and Caucasian women presenting with symptoms of POP. METHODS: This was a prospective observational study of East Asian and Caucasian women presenting with symptoms of POP to a tertiary urogynecology clinic in, respectively, Hong Kong and Sydney. Demographic data, prolapse symptoms and prolapse stage were assessed. Physical examination was performed using the pelvic organ prolapse quantification (POP-Q) system. All women underwent transperineal ultrasound using Voluson systems. Offline analysis of four-dimensional ultrasound volume data was performed at a later date, by one operator blinded to all clinical data, to ascertain pelvic organ descent and hiatal dimensions on Valsalva maneuver. Levator muscle avulsion was assessed in volumes obtained on pelvic floor muscle contraction. Multiple logistic regression analysis was performed to assess factors associated with prolapse on clinical and ultrasound examinations. RESULTS: A total of 225 East Asian women were included between July 2012 and February 2014 from the Hong Kong clinic and 206 Caucasian women between January 2015 and July 2016 from the Sydney clinic. There was no significant difference in the overall staging of prolapse. However, in East Asian women, compared with Caucasians, apical compartment prolapse was more common (99.6% vs 71.8%, P < 0.001) and posterior compartment prolapse less common (16.9% vs 48.5%, P < 0.001) on POP-Q examination. On Valsalva maneuver, the position of the uterus was lower in East Asian than in Caucasian women (-11.3 vs 1.35 mm, P < 0.001), while the rectal ampulla position was lower in Caucasians than in East Asians (-10.6 vs - 4.1 mm, P < 0.001). On multiple regression analysis, Caucasian ethnicity was a significant factor for lower risk of apical compartment prolapse on clinical assessment (odds ratio (OR), 0.01; P < 0.001) and on ultrasound (OR, 0.13; P < 0.001), and for a higher risk of posterior compartment prolapse on clinical assessment (OR, 4.36; P < 0.001) and of true rectocele on ultrasound (OR, 8.14; P < 0.001). CONCLUSIONS: East Asian women present more commonly with uterine prolapse while Caucasians show more often posterior compartment prolapse. Ethnicity was a significant predictor of type of prolapse on multivariate analysis. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Mesh-related complications from reconstructive surgery for pelvic organ prolapse in Chinese patients in Hong Kong.

INTRODUCTION: Mesh-related complications from reconstructive surgery for pelvic organ prolapse are of international concern. The present study aimed to review the incidence, management, and surgical outcomes of mesh-related complications in a Chinese population compared with existing studies involving Western populations. METHODS: This was an analysis of a prospectively collected cohort. Laparoscopic sacrocolpopexy, laparoscopic hystercolposacropexy, or transvaginal mesh surgery were offered with or without concomitant vaginal hysterectomy or continence surgery. Patients were followed up and mesh-related complications were noted. RESULTS: Overall, 276 Chinese women who received mesh surgery were included for data analysis. There were 22 mesh-related complications found during a mean follow-up period of 40 months. Mesh exposure accounted for 20 these complications; significantly more occurred after transvaginal than after abdominal mesh surgery (16 vs 4; P=0.01). Median duration from primary operation to the time of mesh exposure detection was 12 months (interquartile range=4.8-32.8 months). Ten patients required surgical excisions of exposed mesh. The re-operation rate after mesh complications was 6.7% (9/134) for transvaginal mesh surgery and 1.4% (2/142) for laparoscopic sacrocolpopexy (P=0.03). All excisions were performed transvaginally and 95% remained well after surgery. Occurrence of mesh exposure was higher in transvaginal mesh surgery (adjusted odds ratio=6.1; P=0.008), in sexually active patients (adjusted odds ratio=5.4; P=0.002), and in obese patients (adjusted odds ratio=3.7; P=0.046). Over 90% were satisfied with the outcome, regardless of mesh complications. CONCLUSIONS: The rates of mesh exposure and re-operation were consistent with those reported in the literature, suggesting no significant differences in outcome between Chinese and Western patients for this type of surgery.

Immediate and short-term effects of gait retraining on the knee joint moments and symptoms in patients with early tibiofemoral joint osteoarthritis: a randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of a knee adduction moment (KAM) gait retraining in patients with early knee osteoarthritis up to 6 months post-training. METHOD: We conducted a single blinded randomized controlled trial on a total of 23 patients with early knee osteoarthritis who were randomly allocated to the gait retraining group and walking exercise group. Twenty of them completed the corresponding training and the 6-month evaluation. We measured KAM, knee flexion moment (KFM) and western ontario and McMaster universities osteoarthritis index (WOMAC) osteoarthritis index before, immediate after, and 6 months after training. A repeated measures analysis of covariance (ANCOVA) was used to compare KAM, KFM and WOMAC osteoarthritis index scores across the three time points i.e., pre-training, post-training, and 6-month follow-up with gender, knee osteoarthritis severity, and pre-training KAM, KFM and WOMAC scores set as covariates. Post-hoc analyses were conducted when indicated. RESULTS: Significant time × group interactions were found for both KAM and WOMAC osteoarthritis index scores (P < 0.002). No interaction was found for KFM (P = 0.123). KAM after gait retraining was significantly lower than the pre-training value (P < 0.001) and such effect was maintained at 6-month follow-up (P = 0.01). There was no significant difference in the KAM across time in the walking exercise group (P > 0.208). WOMAC osteoarthritis index score after training and score at the 6-month follow-up were significantly improved in the gait retraining group (P = 0.001), while the WOMAC osteoarthritis index score remained similar. CONCLUSIONS: Gait retraining is an effective intervention to reduce KAM during walking and to improve the symptoms of patients with early knee osteoarthritis in short term.

Systematic review with meta-analysis: effectiveness and tolerability of interferon-free direct-acting antiviral regimens for chronic hepatitis C genotype 1 in routine clinical practice in Asia.

BACKGROUND: Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking. AIM: To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia. METHODS: We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017. The pooled SVR rates were computed with a random-effects model. Subgroup analysis and meta-regression as previously registered in PROSPERO were performed to determine how pre-planned variables might have affected the pooled estimates. RESULTS: We included 41 studies from eight countries and regions, comprising of 8574 individuals. The pooled SVR rates for GT1 were 89.9% (95% CI 88.6-91.1, I2  = 55.1%) with daclatasvir/asunaprevir (DCV/ASV) and 98.1% (95% CI 97.0-99.0, I2  = 41.0%) with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV). Baseline cirrhosis but not prior treatment history and age, attenuated the effectiveness of both regimens. Baseline resistance associated substitutions (RASs) severely attenuated SVR of DCV/ASV (65.4% vs 94.3%, P < 0.001) and only minimally with LDV/SOF ± RBV (94.5% vs 99.2%, P = 0.003). Patients with renal dysfunction treated with DCV/ASV showed a higher SVR rate (93.9% vs 89.8%, P = 0.046). Patients with hepatocellular carcinoma (HCC) LDV/SOF ± RBV achieved a lower SVR than those without HCC (94.1% vs 98.7%, P = 0.001). CONCLUSION: All oral DAA treatment of HCV GT1 resulted in high cure rates in Asian patients in routine clinical practice setting including elderly patients and those with end-stage renal disease.

Effect of foot progression angle adjustment on the knee adduction moment and knee joint contact force in runners with and without knee osteoarthritis.

BACKGROUND: Knee adduction moment (KAM) is often used as a surrogate marker of knee contact force (KCF) during walking. Previous studies have reported potential benefits to reduce KAM in patients with knee osteoarthritis (OA) by foot progression angle adjustment. However, KAM is an external moment and it does not consider any muscle contribution to the joint loading, which should pose a greater influence in running than walking. RESEARCH QUESTION: This study used a computational model to compare KAM and KCF between runners with and without knee OA during running. In addition, we evaluated the KAM and KCF when runners adjusted to an out-toe running style. METHODS: Kinematic, kinetic, and lower limb EMG data were collected from 9 runners with knee OA and 10 healthy counterparts. They were asked to run at their usual speed with standard shoes on an instrumented treadmill. RESULTS: We found no significant difference in the KAM during running between OA and the healthy group (p > 0.376). However, runners with knee OA exhibited a greater total KCF than the healthy counterparts (p < 0.041). We did not observe any reduction in KAM after foot progression angle adjustment (p > 0.346). Surprisingly, an increase in the longitudinal KCF and total KCF were found with adjustment of foot progression angle (p < 0.046). SIGNIFICANCE: Unlike the findings reported by the previous walking trials, our findings do not support the notion that foot progression angle adjustment would lead to a lower joint loading during running.

Longitudinal pelvic floor biometry: which factors affect it?

OBJECTIVES: To evaluate pelvic floor biometry of women 3-5 years after their first delivery. The effect of a subsequent delivery and the mode of delivery on pelvic floor biometry were also studied. METHODS: Three-hundred and twenty-eight women who had been examined by translabial ultrasound during their first singleton pregnancy and at 8 weeks and 1 year postpartum, were invited for a follow-up 3-5 years later. The positions of the bladder neck, cervix, anorectal junction and hiatal area (HA) were evaluated using translabial ultrasound. The effects of parity, mode of delivery and levator ani muscle avulsion were studied. RESULTS: A total of 240 women completed the study. Of these, 179 had one or more vaginal deliveries (VD) (VD-only group), 52 had one or more Cesarean sections (CS) (CS-only group) and nine had both VD and CS at follow-up. The mean interval between the first delivery and follow-up was 3.8 years. A significantly lower bladder neck and anorectal junction on Valsalva, a lower cervix at rest, on Valsalva and pelvic floor muscle contraction, and a greater HA were observed in the VD-only group at follow-up, compared with findings at 1 year of follow-up or in the first pregnancy. The findings were similar in the CS-only group, except without a lower anorectal junction on Valsalva. Compared with the primiparous VD-only group, a greater HA at rest was observed in the multiparous VD-only group (P = 0.027). The VD-only group had a greater HA than the CS-only group. CONCLUSIONS: At 3-5 years after first delivery, a lower bladder neck, cervix and anorectal junction, and a greater HA were observed compared with findings in the first trimester and at 1 year of follow-up, regardless of parity or mode of delivery. Women with two or more VDs had a greater HA compared with those who had only one VD, and women with at least one VD had a greater HA compared with those who delivered by CS only.

Levator ani muscle avulsion is a risk factor for expulsion within 1 year of vaginal pessary placed for pelvic organ prolapse.

OBJECTIVE: The aim of this study was to investigate whether the presence of levator ani muscle (LAM) avulsion is associated with expulsion within 1 year of a vaginal pessary placed for pelvic organ prolapse (POP). METHODS: This was a prospective observational study of consecutive women with symptomatic POP, who had not received treatment for the condition before the consultation and opted for vaginal pessary placement in our center. Volume acquisition was performed before pessary insertion and offline analysis of the 3D/4D transperineal ultrasound volume data was performed. LAM was assessed on maximum pelvic floor muscle contraction (PFMC) and hiatal dimensions were assessed at rest, on PFMC and on maximum Valsalva. Results were compared between women in whom the pessary was retained for 1 year and those in whom the pessary was expelled within 1 year. RESULTS: The datasets of 255 women were analyzed including 147 (57.6%) women who had a vaginal pessary continuously in place over 1 year and 108 (42.4%) with pessary expulsion. Mean age was 63.2 (SD, 9.9) years and median parity was 3 (2-4). Eighteen (7.1%) had Stage I, 164 (64.3%) Stage II, 67 (26.3%) Stage III and six (2.4%) Stage IV POP. Women with vaginal pessary expulsion within 1 year had significantly larger hiatal dimensions at rest and on Valsalva, larger hiatal area during rest, PFMC and Valsalva and higher rate of LAM avulsion (53.7% vs 27.2%, P < 0.01) compared with women in whom the pessary was retained for 1 year. After controlling for potential confounders, LAM avulsion remained a risk factor (OR, 3.18, P < 0.01) of vaginal pessary expulsion within 1 year. CONCLUSIONS: Women in whom a vaginal pessary was expelled within 1 year of placement for POP had a larger hiatus. Presence of LAM avulsion was associated with a three-fold increase in the risk of expulsion of a vaginal pessary within 1 year. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Longitudinal follow-up of levator ani muscle avulsion: does a second delivery affect it?

OBJECTIVES: To evaluate the morphological outcome of levator ani muscle (LAM) avulsion 3-5 years after a first delivery and to assess the effect of a second delivery on this condition. The impact of LAM avulsion on pelvic floor disorders was also studied. METHODS: Six hundred and sixty-six women who had been assessed for LAM avulsion 8 weeks after their first delivery were invited for a follow-up examination 3-5 years later. Women completed the Pelvic Floor Distress Inventory including the Urinary Distress Inventory (UDI) and Pelvic Organ Prolapse Distress Inventory (POPDI) questionnaires to explore symptoms of pelvic floor disorders, and the pelvic floor was examined using three-dimensional translabial ultrasound and assessed using the pelvic organ prolapse quantification system. RESULTS: Three hundred and ninety-nine women completed the study, of whom 151 were multiparous. Mean interval between first delivery and follow-up was 42.3 ± 7.6 months. Among 69 women who had LAM avulsion 8 weeks after their first delivery, nine (13.0%) had no LAM avulsion at follow-up. One (0.9%) woman had a new LAM avulsion after her second vaginal delivery. A greater proportion of women with LAM avulsion reported symptoms of stress urinary incontinence (SUI) (adjusted odds ratio, 2.09 (95% CI, 1.18-3.70); P = 0.01) and symptoms of prolapse than did women without avulsion; however, this difference did not reach statistical significance (P = 0.61). Women with LAM avulsion had higher UDI and POPDI scores than did women without avulsion (median UDI score, 17.7 (interquartile range (IQR), 5.0-32.4) vs 9.2 (IQR, 0.0-22.1); P = 0.045 and median POPDI score, 20.8 (IQR, 8.8-40.5) vs 10.7 (IQR, 0.0-32.8); P = 0.021). CONCLUSIONS: The risk of developing new LAM avulsion after a second vaginal delivery is low (0.9%). Healing of LAM avulsion was observed in 13% of women who had at least one vaginal delivery. At 3-5 years after delivery, women with LAM avulsion reported symptoms of SUI more often than did those without, and had higher UDI and POPDI scores, implying more bothersome symptoms.

Parecoxib, propacetamol, and their combination for analgesia after total hip arthroplasty: a randomized non-inferiority trial.

BACKGROUND: This study assessed non-inferiority of parecoxib vs. combination parecoxib+propacetamol and compared the opioid-sparing effects of parecoxib, propacetamol, and parecoxib+propacetamol vs. placebo after total hip arthroplasty. METHODS: In this randomized, placebo-controlled, parallel-group, non-inferiority study, patients received one of four IV treatments after surgery: parecoxib 40 mg bid (n = 72); propacetamol 2 g qid (n = 71); parecoxib 40 mg bid plus propacetamol 2 g qid (n = 72); or placebo (n = 38) with supplemental IV patient-controlled analgesia (morphine). Patients and investigators were blinded to treatment. Pain intensity at rest and with movement was assessed regularly, together with functional recovery (modified Brief Pain Inventory-Short Form) and opioid-related side effects (Opioid-Related Symptom Distress Scale) questionnaires up to 48 h. RESULTS: After 24 h, cumulative morphine consumption was reduced by 59.8% (P < 0.001), 38.9% (P < 0.001), and 26.8% (P = 0.005) in the parecoxib+propacetamol, parecoxib, and propacetamol groups, respectively, compared with placebo. Parecoxib did not meet criteria for non-inferiority to parecoxib+propacetamol. Parecoxib+propacetamol and parecoxib significantly reduced least-squares mean pain intensity scores at rest and with movement compared with propacetamol (P < 0.05). One day after surgery, parecoxib+propacetamol significantly reduced opioid-related symptom distress and decreased pain interference with function compared with propacetamol or placebo. CONCLUSION: Parecoxib and parecoxib+propacetamol provided significant opioid-sparing efficacy compared with placebo; non-inferiority of parecoxib to parecoxib+propacetamol was not demonstrated. Opioid-sparing efficacy was accompanied by significant reductions in pain intensity on movement, improved functional outcome, and less opioid-related symptom distress. Study medications were well tolerated.

The 2014 Survey on Living with Chronic Diseases in Canada on Mood and Anxiety Disorders: a methodological overview. / Enquête sur les personnes ayant une maladie chronique au Canada ­ Composante des troubles de l'humeur et d'anxiété, 2014 : aperçu de la méthodologie.

INTRODUCTION: There is a paucity of information about the impact of mood and anxiety disorders on Canadians and the approaches used to manage them. To address this gap, the 2014 Survey on Living with Chronic Diseases in Canada-Mood and Anxiety Disorders Component (SLCDC-MA) was developed. The purpose of this paper is to describe the methodology of the 2014 SLCDC-MA and examine the sociodemographic characteristics of the final sample. METHODS: The 2014 SLCDC-MA is a cross-sectional follow-up survey that includes Canadians from the 10 provinces aged 18 years and older with mood and/or anxiety disorders diagnosed by a health professional that are expected to last, or have already lasted, six months or more. The survey was developed by the Public Health Agency of Canada (PHAC) through an iterative, consultative process with Statistics Canada and external experts. Statistics Canada performed content testing, designed the sampling frame and strategies and collected and processed the data. PHAC used descriptive analyses to describe the respondents' sociodemographic characteristics, produced nationally representative estimates using survey weights provided by Statistics Canada, and generated variance estimates using bootstrap methodology. RESULTS: The final 2014 SLCDC-MA sample consists of a total of 3361 respondents (68.9% response rate). Among Canadian adults with mood and/or anxiety disorders, close to twothirds (64%) were female, over half (56%) were married/in a common-law relationship and 60% obtained a post-secondary education. Most were young or middle-aged (85%), Canadian born (88%), of non-Aboriginal status (95%), and resided in an urban setting (82%). Household income was fairly evenly distributed between the adequacy quintiles; however, individuals were more likely to report a household income adequacy within the lowest (23%) versus highest (17%) quintile. Forty-five percent reported having a mood disorder only, 24% an anxiety disorder only and 31% both kinds of disorder. CONCLUSION: The 2014 SLCDC-MA is the only national household survey to collect information on the experiences of Canadians living with a professionally diagnosed mood and/or anxiety disorder. The information collected offers insights into areas where additional support or interventions may be needed and provides baseline information for future public health research in the area of mental illness.

INTRODUCTION: Il existe peu de données à propos des répercussions des troubles de l'humeur et d'anxiété sur les Canadiens et sur la gestion de ces troubles. L'Enquête sur les personnes ayant une maladie chronique au Canada ­ Composante des troubles de l'humeur et d'anxiété (EPMCC-THA) de 2014 a été élaborée pour combler les lacunes à ce chapitre. Le but du présent article est de décrire la méthodologie de l'EPMCC-THA de 2014 et de présenter les caractéristiques sociodémographiques de l'échantillon final. MÉTHODOLOGIE: L'EPMCC-THA de 2014 est une enquête transversale de suivi menée auprès de Canadiens des 10 provinces âgés de 18 ans et plus qui souffrent d'un trouble de l'humeur ou d'anxiété diagnostiqué par un professionnel de la santé et dont on s'attend à ce qu'il dure (ou durant depuis déjà) six mois ou plus. L'enquête a été élaborée par l'Agence de la santé publique du Canada (ASPC) au moyen d'un processus itératif et consultatif avec Statistique Canada et des experts externes. Statistique Canada a mis à l'essai le contenu, a conçu la base et les stratégies d'échantillonnage et a recueilli et traité les données. L'ASPC a procédé à des analyses descriptives pour déterminer les caractéristiques sociodémographiques des répondants, a produit des estimations représentatives à l'échelle nationale à l'aide des coefficients de pondération fournis par Statistique Canada et a produit des estimations de la variance à l'aide de la méthode bootstrap. RÉSULTATS: L'échantillon final de l'EPMCC-THA de 2014 était constitué de 3 361 répondants (taux de réponse de 68,9 %). Parmi ceux qui vivaient avec un trouble de l'humeur ou d'anxiété, près des deux tiers (64 %) étaient des femmes, près de la moitié (56 %) étaient mariés ou vivaient en union libre et 60 % avaient obtenu un diplôme d'études postsecondaires. La plupart étaient jeunes ou d'âge moyen (85 %), étaient nés au Canada (88 %), étaient non Autochtones (95 %) et vivaient en milieu urbain (82 %). Le revenu du ménage était distribué assez également entre les quintiles de suffisance du revenu avec cependant un revenu déclaré plus souvent dans le quintile le plus bas (23 %) que dans le plus haut (17 %). Quarante-cinq pour cent ont déclaré avoir un trouble de l'humeur seulement, 24 %, un trouble d'anxiété seulement et 31 %, les deux types de trouble. CONCLUSION: L'EPMCC-THA de 2014 est la seule enquête nationale auprès des ménages ayant recueilli de l'information sur les expériences des Canadiens avec un trouble de l'humeur ou d'anxiété diagnostiqué par un professionnel de la santé. Cette information permet de déterminer les secteurs où un soutien ou des interventions supplémentaires pourraient être requis et fournit un support aux futurs travaux de recherche en santé publique dans le domaine des maladies mentales.
