Meta-Analysis Review
OBJECTIVE
To evaluate the likelihood of developing de novo erectile dysfunction (ED) after anterior urethroplasty and to determine if this likelihood is influenced by age, stricture length, number of previous procedures or timing of evaluation.
MATERIALS AND METHODS
PubMed, Embase, Cochrane, and Google Scholar databases were searched for the terms 'urethroplasty', 'urethral obstruction', 'urethral stricture', 'sexual function', 'erection', 'erectile function', 'erectile dysfunction', 'impotence' and 'sexual dysfunction'. Two reviewers evaluated articles for inclusion based on predetermined criteria.
RESULTS
In a meta-analysis of 36 studies with a total of 2323 patients, de novo ED was rare, with an incidence of 1%. In studies that assessed postoperative erectile function at more than one time point, ED was transient and resolved at between 6 and 12 months in 86% of cases.
CONCLUSIONS
Men should be counselled regarding the possibility of transient or permanent de novo ED after anterior urethroplasty procedures. Increasing mean age was associated with an increased likelihood of de novo ED, but this was not statistically significant.

Review
BACKGROUND
Cholecystectomy is the preferred treatment option for symptomatic gallstones, but the exact relationship between cholecystectomies and symptoms still is unclear. This study aimed to assess the effectiveness of elective cholecystectomy for patients with cholecystolithiasis in terms of both persistent and de novo symptoms.
METHODS
A systematic literature search was conducted in Pubmed and Embase. The search included studies comprising patients 18 years of age or older undergoing elective cholecystectomy for symptomatic cholecystolithiasis. The proportions of symptoms after cholecystectomy were calculated and then subdivided into persistent and de novo symptoms.
RESULTS
A total of 38 studies reported the presence of postcholecystectomy symptoms. The results showed that upper abdominal pain, the main indication for cholecystectomy in the majority of the patients, mostly disappeared after surgery. However, it persisted in up to 33 % of the patients and arose de novo in up to 14 %. Diarrhea (85 %) and constipation (76 %) were the persistent symptoms most often reported, whereas upper abdominal pain and vomiting were the least often reported. Flatulence (62 %) was the most often reported new symptom. However, large variations in symptoms were found between studies.
CONCLUSIONS
The review indicates that cholecystectomy often is ineffective with regard to persistent and de novo symptoms. The finding that the types and proportions of persistent symptoms differ from those that arise de novo suggests that this distinction may be useful in predicting which patients would and which would not benefit from a cholecystectomy.

Meta-Analysis
Cytomegalovirus (CMV) infection does not usually produce symptoms when it causes primary infection, reinfection, or reactivation because these three types of infection are all controlled by the normal immune system. However, CMV becomes an important pathogen in individuals whose immune system is immature or compromised, such as the unborn child. Several vaccines against CMV are currently in clinical trials that aim to induce immunity in seronegative individuals and/or to boost the immunity of those with prior natural infection (seropositives). To facilitate estimation of the burden of disease and the need for vaccines that induce de novo immune responses or that boost pre-existing immunity to CMV, we conducted a systematic survey of the published literature to describe the global seroprevalence of CMV IgG antibodies. We estimated a global CMV seroprevalence of 83% (95%UI: 78-88) in the general population, 86% (95%UI: 83-89) in women of childbearing age, and 86% (95%UI: 82-89) in donors of blood or organs. For each of these three groups, the highest seroprevalence was seen in the World Health Organisation (WHO) Eastern Mediterranean region 90% (95%UI: 85-94) and the lowest in WHO European region 66% (95%UI: 56-74). These estimates of the worldwide CMV distribution will help develop national and regional burden of disease models and inform future vaccine development efforts.

Meta-Analysis Review
INTRODUCTION AND HYPOTHESIS
De novo overactive bladder (OAB) is a known complication of midurethral sling surgery for the treatment of stress urinary incontinence. To date, differences in the incidence of de novo OAB following the use of different types of midurethral sling remain relatively unknown. The purpose of the present systematic review was to evaluate this incidence and summarize current evidence.
METHODS
We systematically searched the literature using the MEDLINE, Embase, Scopus, ClinicalTrials.gov, LILACS and Cochrane Central Register of Controlled Trials databases as well as the grey literature and references from the electronically retrieved articles. For comparisons of proportions, we used the chi-squared test. All reported analyses were designed as two-tailed. Statistical significance was set at p < 0.05.
RESULTS
Finally, 32 studies were included in this systematic review, with a total of 3,139 patients who had undergone midurethral sling procedures that included transobturator tapes (TOT), retropubic tapes (TVT) or single-incision tapes (mini-slings). The overall incidence of de novo OAB was 11.5% in nonrandomized studies (280 women) and 6.4% in randomized studies (50 women). In relation to the type of midurethral sling, the incidence of de novo OAB was 9.7% for mini-slings, 11.2% for TVT-O, 8.7% for TOT and 9.8% for TVTs. The chi-squared test did not reveal significant differences (p = 0.58).
CONCLUSIONS
Current evidence suggests that the overall incidence of de novo OAB following midurethral sling procedures is approximately 9%. There is not enough evidence to support differences in the effects of the different types of sling with regard to this particular postoperative complication.

Nicotinamide adenine dinucleotide (NAD+) is an essential pyridine nucleotide that is present in all living cells. NAD+ acts as an important cofactor and substrate for a multitude of biological processes including energy production, DNA repair, gene expression, calcium-dependent secondary messenger signalling and immunoregulatory roles. The de novo synthesis of NAD+ is primarily dependent on the kynurenine pathway (KP), although NAD+ can also be recycled from nicotinic acid (NA), nicotinamide (NAM) and nicotinamide riboside (NR). NAD+ levels have been reported to decline during ageing and age-related diseases. Recent studies have shown that raising intracellular NAD+ levels represents a promising therapeutic strategy for age-associated degenerative diseases in general and to extend lifespan in small animal models. A systematic review of the literature available on Medline, Embase and Pubmed was undertaken to evaluate the potential health and/or longevity benefits due to increasing NAD+ levels. A total of 1545 articles were identified and 147 articles (113 preclinical and 34 clinical) met criteria for inclusion. Most studies indicated that the NAD+ precursors NAM, NR, nicotinamide mononucleotide (NMN), and to a lesser extent NAD+ and NADH had a favourable outcome on several age-related disorders associated with the accumulation of chronic oxidative stress, inflammation and impaired mitochondrial function. While these compounds presented with a limited acute toxicity profile, evidence is still quite limited and long-term human clinical trials are still nascent in the current literature. Potential risks in raising NAD+ levels in various clinical disorders using NAD+ precursors include the accumulation of putative toxic metabolites, tumorigenesis and promotion of cellular senescence. Therefore, NAD+ metabolism represents a promising target and further studies are needed to recapitulate the preclinical benefits in human clinical trials.

Journal of Obstetrics and Gynaecology... Apr 2021To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To compare success and complication rates of apical suspension procedures for the surgical management of symptomatic uterine or vaginal vault prolapse.
TARGET POPULATION
Women with symptomatic uterine or vaginal vault prolapse seeking surgical correction.
OPTIONS
Interventions included abdominal apical reconstructive repairs (sacrocolpopexy, sacrohysteropexy, or uterosacral hysteropexy) via open, laparoscopic, or robotic approaches; vaginal apical reconstructive repairs (vault suspensions or hysteropexy, sacrospinous, uterosacral, iliococcygeus, McCall's, or Manchester types); and vaginal obliterative procedures (with or without uterus in situ). Individual procedures or broad categories of procedures were compared: (1) vaginal versus abdominal routes for reconstruction, (2) abdominal procedures for reconstruction, (3) vaginal procedures for reconstruction, (4) hysterectomy and suspension versus hysteropexy for reconstruction, and (5) reconstructive versus obliterative options.
OUTCOMES
The Urogynaecology Committee selected outcomes of interest: objective failure (obtained via validated pelvic organ prolapse [POP] quantification systems and defined as overall objective failure as well as failure rate by compartment); subjective failure (recurrence of bulge symptoms determined subjectively, with or without use of a validated questionnaire); reoperation for POP recurrence; complications of postoperative lower urinary tract symptoms (de novo or postoperative stress urinary incontinence; reoperation for persistent, recurrent, or de novo stress urinary incontinence; urge urinary incontinence; and voiding dysfunction); perioperatively recognized urinary tract injury (bladder or ureter); other complications (mesh exposure, defined as mesh being visible and exposed in the vagina, and non-sexual pelvic pain); and sexual function (de novo dyspareunia and sexual function score according to a validated questionnaire).
BENEFITS, HARMS, AND COSTS
This guideline will benefit patients seeking surgical correction of apical POP by improving counselling on surgical treatment options and possible outcomes. It will also benefit surgical providers by improving their knowledge of various surgical approaches. Data presented could be used to develop frameworks and tools for shared decision-making.
EVIDENCE
We searched Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase from 2002 to 2019. The search included multiple terms for apical POP surgical procedures, approaches, and complications. We excluded POP repairs using transvaginal mesh and studies that compared procedures without apical suspension. We included randomized controlled trials and prospective or retrospective comparative studies. We limited language of publication to English and French and accessibility to full text. A systematic review and meta-analysis was performed.
VALIDATION METHODS
The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations).
INTENDED USERS
Gynaecologists, urologists, urogynaecologists, and other health care providers who assess, counsel, and care for women with POP.
SUMMARY STATEMENTS
All statements refer to correction of apical vaginal prolapse in the short and medium term (up to 5 years), except when otherwise specified.

Review
De Novo Vesicoureteral Reflux Following Ureterocele Decompression in Children: A Systematic Review and Meta-Analysis Comparing Laser Puncture versus Electrosurgical Incision Techniques.
BACKGROUND
The available endoscopic techniques for ureterocele decompression include laser puncture (LP), electrosurgical incision (ES), and cold-knife incision. This systematic review was performed to compare the efficacy of LP versus ES techniques with special emphasis on de novo VUR.
METHODS
Four databases were systematically searched by the authors. The inclusion criteria were all comparative studies in which ureterocele decompression was performed by either LP or ES endoscopic techniques. Outcomes including the incidence of de novo VUR, the need for endoscopic retreatment of the ureterocele, and the need for secondary surgical procedures were studied. Risk ratios (RR) were calculated for all outcomes and the Mantel-Haenszel method was utilized for the estimation of pooled RR. The methodological quality was assessed by the Downs and Black scale.
RESULTS
Five studies were considered for systematic review, while four of them were included in the meta-analysis. Out of 202 children, 67 developed de novo VUR. Significantly lower rates of reflux were observed in the LP group vis-a-vis ES group (RR = 0.17, 95% CI 0.09 to 0.32, 0.00001). Endoscopic retreatment rates ( = 20) demonstrated no significant difference among the two patient groups (RR = 0.66, 95% CI 0.26-1.68, = 0.38). A total of 46 secondary procedures were performed in 170 children, mostly ureteral re-implantations, with a significantly lower need of secondary surgeries following LP versus ES (RR = 0.26, 95% CI 0.13-0.49, 0.0001). The risk of bias in the included studies was low-to-moderate.
CONCLUSIONS
When compared to the ES technique, the LP technique is associated with a significantly low incidence of de novo VUR and requirement for secondary surgeries (particularly anti-reflux surgeries). Endoscopic retreatment rates showed no significant difference between the two techniques. However, due to the moderate risk of bias in two out of four included studies, randomized controlled trials are needed in the future.

Meta-Analysis
UNLABELLED
Patients with conventional pacemakers or implanted defibrillators are often considered for cardiac resynchronization therapy (CRT). Our aim was to summarize the available evidences regarding the clinical benefits of upgrade procedures. A systematic literature search was performed from studies published between 2006 and 2017 in order to compare the outcome of CRT upgrade vs. de novo implantations. Outcome data on all-cause mortality, heart failure events, New York Heart Association (NYHA) Class, QRS narrowing and echocardiographic parameters were analysed. A total of 16 reports were analysed comprising 489,568 CRT recipients, of whom 468,205 patients underwent de novo and 21,363 upgrade procedures. All-cause mortality was similar after CRT upgrade compared to de novo implantations (RR 1.19, 95% CI 0.88-1.60, p = 0.27). The risk of heart failure was also similar in both groups (RR 0.96, 95% CI 0.70-1.32, p = 0.81). There was no significant difference in clinical response after CRT upgrade compared to de novo implantations in terms of improvement in left ventricular ejection fraction (ΔEF de novo - 6.85% vs. upgrade - 9.35%; p = 0.235), NYHA class (ΔNYHA de novo - 0.74 vs. upgrade - 0.70; p = 0.737) and QRS narrowing (ΔQRS de novo - 9.6 ms vs. upgrade - 29.5 ms; p = 0.485). Our systematic review and meta-analysis of currently available studies reports that CRT upgrade is associated with similar risk for all-cause mortality compared to de novo resynchronization therapy. Benefits on reverse remodelling and functional capacity improved similarly in both groups suggesting that CRT upgrade may be safely and effectively offered in routine practice.

The Cochrane Database of Systematic... Apr 2013Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with the prolapse. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with the prolapse.
OBJECTIVES
To determine the effects of the many different surgeries used in the management of pelvic organ prolapse.
SEARCH METHODS
We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In Process and handsearching of journals and conference proceedings, healthcare-related bibliographic databases, handsearched conference proceedings (searched 20 August 2012), and reference lists of relevant articles. We also contacted researchers in the field.
SELECTION CRITERIA
Randomised or quasi-randomised controlled trials that included surgical operations for pelvic organ prolapse.
DATA COLLECTION AND ANALYSIS
Trials were assessed and data extracted independently by two review authors. Six investigators were contacted for additional information with five responding.
MAIN RESULTS
Fifty-six randomised controlled trials were identified evaluating 5954 women. For upper vaginal prolapse (uterine or vault) abdominal sacral colpopexy was associated with a lower rate of recurrent vault prolapse on examination and painful intercourse than with vaginal sacrospinous colpopexy. These benefits must be balanced against a longer operating time, longer time to return to activities of daily living and increased cost of the abdominal approach. In single studies the sacral colpopexy had a higher success rate on examination and lower reoperation rate than high vaginal uterosacral suspension and transvaginal polypropylene mesh.Twenty-one trials compared a variety of surgical procedures for anterior compartment prolapse (cystocele). Ten compared native tissue repair with graft (absorbable and permanent mesh, biological grafts) repair for anterior compartment prolapse. Native tissue anterior repair was associated with more recurrent anterior compartment prolapse than when supplemented with a polyglactin (absorbable) mesh inlay (RR 1.39, 95% CI 1.02 to 1.90) or porcine dermis mesh inlay (RR 2.08, 95% CI 1.08 to 4.01), however there was no difference in post-operative awareness of prolapse after absorbable mesh (RR 0.96, 95% CI 0.33 to 2.81) or a biological graft (RR 1.21, 95% CI 0.64 to 2.30). Data on morbidity and other clinical outcomes were lacking. Standard anterior repair was associated with more anterior compartment prolapse on examination than for any polypropylene (permanent) mesh repair (RR 3.15, 95% CI 2.50 to 3.96). Awareness of prolapse was also higher after the anterior repair as compared to polypropylene mesh repair (28% versus 18%, RR 1.57, 95% CI 1.18 to 2.07). However, the reoperation rate for prolapse was similar at 14/459 (3%) after the native tissue repair compared to 6/470 (1.3%) (RR 2.18, 95% CI 0.93 to 5.10) after the anterior polypropylene mesh repair and no differences in quality of life data or de novo dyspareunia were identified. Blood loss (MD 64 ml, 95% CI 48 to 81), operating time (MD 19 min, 95% CI 16 to 21), recurrences in apical or posterior compartment (RR 1.9, 95% CI 1.0 to 3.4) and de novo stress urinary incontinence (RR 1.8, 95% CI 1.0 to 3.1) were significantly higher with transobturator meshes than for native tissue anterior repair. Mesh erosions were reported in 11.4% (64/563), with surgical interventions being performed in 6.8% (32/470).Data from three trials compared native tissue repairs with a variety of total, anterior, or posterior polypropylene kit meshes for vaginal prolapse in multiple compartments. While no difference in awareness of prolapse was able to be identified between the groups (RR 1.3, 95% CI 0.6 to 1.7) the recurrence rate on examination was higher in the native tissue repair group compared to the transvaginal polypropylene mesh group (RR 2.0, 95% CI 1.3 to 3.1). The mesh erosion rate was 35/194 (18%), and 18/194 (9%) underwent surgical correction for mesh erosion. The reoperation rate after transvaginal polypropylene mesh repair of 22/194 (11%) was higher than after the native tissue repair (7/189, 3.7%) (RR 3.1, 95% CI 1.3 to 7.3).Data from three trials compared posterior vaginal repair and transanal repair for the treatment of posterior compartment prolapse (rectocele). The posterior vaginal repair had fewer recurrent prolapse symptoms (RR 0.4, 95% CI 0.2 to 1.0) and lower recurrence on examination (RR 0.2, 95% CI 0.1 to 0.6) and on defecography (MD -1.2 cm, 95% CI -2.0 to -0.3).Sixteen trials included significant data on bladder outcomes following a variety of prolapse surgeries. Women undergoing prolapse surgery may have benefited from having continence surgery performed concomitantly, especially if they had stress urinary incontinence (RR 7.4, 95% CI 4.0 to 14) or if they were continent and had occult stress urinary incontinence demonstrated pre-operatively (RR 3.5, 95% CI 1.9 to 6.6). Following prolapse surgery, 12% of women developed de novo symptoms of bladder overactivity and 9% de novo voiding dysfunction.
AUTHORS' CONCLUSIONS
Sacral colpopexy has superior outcomes to a variety of vaginal procedures including sacrospinous colpopexy, uterosacral colpopexy and transvaginal mesh. These benefits must be balanced against a longer operating time, longer time to return to activities of daily living, and increased cost of the abdominal approach.The use of mesh or graft inlays at the time of anterior vaginal wall repair reduces the risk of recurrent anterior wall prolapse on examination. Anterior vaginal polypropylene mesh also reduces awareness of prolapse, however these benefits must be weighted against increased operating time, blood loss, rate of apical or posterior compartment prolapse, de novo stress urinary incontinence, and reoperation rate for mesh exposures associated with the use of polypropylene mesh.Posterior vaginal wall repair may be better than transanal repair in the management of rectocele in terms of recurrence of prolapse. The evidence is not supportive of any grafts at the time of posterior vaginal repair. Adequately powered randomised, controlled clinical trials with blinding of assessors are urgently needed on a wide variety of issues, and they particularly need to include women's perceptions of prolapse symptoms. Following the withdrawal of some commercial transvaginal mesh kits from the market, the generalisability of the findings, especially relating to anterior compartment transvaginal mesh, should be interpreted with caution.

Paediatric autoimmune liver disease is characterized by inflammatory liver histology, circulating autoantibodies, and increased levels of IgG, in the absence of a known etiology. Three conditions have a likely autoimmune pathogenesis: autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis, and de novo AIH after liver transplantation. Two types of pediatric AIH are recognized according to seropositivity for smooth muscle and/or antinuclear antibody (AIH-1) or liver kidney microsomal type 1 and/or anti-liver cytosol type 1 antibodies (AIH-2).Pertinent issues addressing the diagnosis, treatment, and long-term follow-up were formulated by a core group of ESPGHAN members. They have commissioned the first authors with execution of this project. Initially, they have performed a systematic literature search on MEDLINE, ResearchGate, and Mendeley databases during the last 30 years and produced a document focusing on prospective and retrospective studies in children. The ESPGHAN core group and ESPGHAN Hepatology Committee members voted on each recommendation, using a formal voting technique.
