Abstract
OBJECTIVE To evaluate the long-term survival and success rates of implants placed in reconstructed areas using microvascularized or non-microvascularized extraoral bone grafts. MATERIALS AND METHODS An electronic search was performed in five databases and in gray literature for articles published until June, 2023. The eligibility criteria comprised observational studies (prospective or retrospective) and clinical trials, reporting survival and success rates of implants placed in extraoral bone grafts. A meta-analysis (implant failure) was categorized into subgroups based on the type of bone graft used. The risk of bias within studies was assessed using the Newcastle-Ottawa Scale. RESULTS Thirty-one studies met the inclusion criteria. The mean follow-up time was 92 months. The summary estimate of survival rate at the implant level were 94.9% (CI: 90.1%-97.4%) for non-vascularized iliac graft, 96.5% (CI: 91.4%-98.6%) for non-vascularized calvaria graft, and 92.3% (CI: 89.1%-94.6%) for vascularized fibula graft. The mean success rate and marginal bone loss (MBL) were 83.2%; 2.25 mm, 92.2%; 0.93 mm, and 87.6%; 1.49 mm, respectively. CONCLUSIONS Implants placed in areas reconstructed using extraoral autogenous bone graft have high long-term survival rates and low long-term MBLs. The data did not demonstrate clinically relevant differences in the survival, success, or MBL of grafts from different donor areas or with different vascularization. This systematic review was registered in INPLASY under number INPLASY202390004.

Abstract
AIM We aimed to investigate predictive factors of successful external cephalic version (ECV) using regional anesthesia. METHODS In this retrospective study, we included women who underwent ECV at our center from 2010 to 2022. The procedure had been conducted using regional anesthesia and the administration of intravenous ritodrine hydrochloride. The primary outcome was the success of ECV, which was defined as the rotation from a non-cephalic to a cephalic presentation. Primary exposures were maternal demographic factors and ultrasound findings at ECV. To determine predictive factors, we conducted a logistic regression analysis. RESULTS Of 622 pregnant women who underwent ECV, missing data on any variables (n = 14) were excluded and the remaining 608 were analyzed. The success rate during the study period was 76.3%. Multiparous women had significantly higher success rates than primiparous women (adjusted odds ratio [OR]: 2.06 [95% confidence interval (CI): 1.31-3.25]). Women with a maximum vertical pocket (MVP) of <4 cm had significantly lower success rates than those with 4 cm < MVP ≤6 cm (OR: 0.56 [95% CI: 0.37-0.86]). The non-anterior placental location was associated with higher success rates than the anterior placental location (OR: 1.46 [95% CI: 1.00-2.17]). CONCLUSIONS Multiparity, MVP >4 cm, and non-anterior placental locations were associated with successful ECV. These three factors could be useful for patient selection for successful ECV.

Abstract
Cardiac resynchronization therapy (CRT) is an important treatment of heart failure patients with reduced left ventricular ejection fraction (LVEF) and asynchrony of cardiac electromechanical activity. Left bundle branch area pacing (LBBaP) is a novel physiological pacing modality that appears to be an effective method for CRT. LBBaP has several advantages over the traditional biventricular-CRT (BiV-CRT), including a low and stable pacing capture threshold, a high success rate of implantation, a short learning curve, and high economic feasibility. However, LBBaP is not suitable for all heart failure patients needing a CRT and the success rates of LBBaP in heart failure patients is lower because of myocardial fibrosis, non-specific intraventricular conduction disturbance (IVCD), enlargement of the right atrium or right ventricle, etc. In this literature review, we summarize the success rates, challenges, and troubleshooting of LBBaP in heart failure patients needing a CRT.

Abstract
Purpose A palatal fistula following the closure of palatal clefts remains a difficult clinical complication. Surgical treatment of fistulas is often complicated, with high recurrence rates. We present our results of fistula closure augmented with GTR, a resorbable membrane designed to promote guided tissue regeneration. Methods We reviewed the records of 75 patients operated on between 2008 and 2022 for closure of the palatal fistula. The patients included 24 who underwent fistula closure augmented with GTR and 51 who underwent fistula closure with other techniques. We reviewed the age at surgery, sex, fistula location, and outcome. Operation success was defined as an asymptomatic patient with a healed fistula on clinical examination. Results The overall fistula closure rate was 79.1% in the GTR group and 76.5% in the non-GTR group(p = 0.79). Discussion The success rate of fistula closure in the GTR group is comparable to that in the non-GTR group in this study. An additional advantage is that this procedure does not require harvesting any autologous tissue and reduces tissue damage in the long term.

Abstract
BACKGROUND We modified the blind Seldinger technique by incorporating ultrasound guidance and the use of a multifunctional bladder paracentesis trocar for PD catheter (PDC) placement, which can be easily performed by a nephrologist and is a feasible technique. To compare success rates and safety of our modified percutaneous PD catheter placement technique to open surgery. METHODS Two hundred and twelve stage-5 chronic kidney disease(CKD) patients receiving PD therapy from June 2016 to June 2019 were included, 105 patients treated by ultrasound-guided percutaneous placement of peritoneal dialysis catheters using a multifunctional bladder paracentesis trocar (Group A) and 107 patients receiving open surgical placement (Group B). Outcomes of patients via either catheter placement technique were retrospectively compared. The clinical success rate as defined by proper catheter drainage within 4 weeks after placement, complication rates (both technical complications and infections), and 1-year catheter survival were compared. RESULTS There was no significant difference in sex ratio, age, or previous abdominal surgery history between groups (P > .05). Both surgical time and incision length were significantly shorter in Group A than in Group B (P < .05). Clinical success rate was also higher inGroup A (P < .05). Moreover, Group A demonstrated lower overall complication rates (P < .05) and lower incidence rates of early peritonitis, initial drainage disorder, and peritubular leakage (all P < .05). One-year catheter survival was also higher in Group A (P < .05). CONCLUSION Percutaneous placement of PD catheters using our modified technique demonstrates superior success rates and safety compared to open surgery. In addition, our modified technique can be a better alternative to traditional Seldinger percutaneous catheterization for its higher success rate and safety, more accurate positioning.

Abstract
AIM To evaluate the clinical and radiographic outcome of single-visit root canal retreatment and to compare the results with conventional two-visit root canal retreatment as control group. METHODOLOGY One hundred root canal-treated, single-rooted asymptomatic teeth with periapical lesion were retreated by one operator. Fifty of the teeth were randomly assigned to the single-visit group and the others were treated in two-visits. In both groups, root canal filling material was removed, and re-instrumentation of the root canal was performed using step-back technique with hand files using 2.5% NaOCl and 5% EDTA as irrigants. In the single-visit group 5 ml 2% chlorhexidine (CHX) were applied as the final irrigation and in the two-visit group, calcium hydroxide paste was placed into the root canal as an interappointment dressing. All root canal obturations were performed with lateral compaction. All patients were followed up for 24 months. Success was determined depending on both healed and healing cases. The chi-square or Fisher's Exact test was used to analyse the differences between the groups for success rates and the factors affecting the outcome. RESULTS The recall rate was 89 (89%). At 24 months, 39 teeth (88.6%) were considered as healed, 3 teeth (6.8%) as healing, and 2 teeth (4.5%) were identified as failed in the single-visit group, while in the two-visit group 39 teeth (86.7%) had healed, 2 teeth (4.4%) were scored as healing, and 4 teeth (8.9%) as failed. There was no statistically significant difference in the success rates between the two groups (P > 0.05). Size of the lesion and the preoperative length of root canal filling had a statistically significant impact on the outcome (P < 0.05). CONCLUSION No statistically significant difference was observed in terms of healing in 24-month follow-up of retreatments completed in single-visit or two-visits in asymptomatic teeth with periapical lesions. Size of the periapical lesion and initial apical level of root canal filling have affected the outcome of root canal retreatment.

Abstract
An objective and individualized approach of in vitro fertilization techniques tends to decrease costs and improve the experience of infertile couples during treatment. The use of available technologies to diagnose and treat infertility based on scientific evidence seems to be the best practice, which is the guideline that motivates this review on the available techniques for laboratory oocyte insemination. Conventional IVF, the pioneering technique, was initially used in the treatment of tubal obstruction infertility, successfully expanding the treatment of infertile couples presenting with several other factors. However, it was less effective in cases of severe male factor infertility. Intracytoplasmic sperm injection, which was developed in 1992, proved to be the method of choice for treating couples with severe male factor infertility. Since then, it has been increasingly used regardless of the infertility factor. This review discusses the effectiveness of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) when the male factor is absent in all aspects, as technical and clinical outcomes, associated risks, adjustments for using with other technologies and costs. Finally we discuss the advantages and disadvantages of each one, with all aspects reviewed.

Abstract
BACKGROUND A descriptive study was designed to determine the relationship between the anxiety levels of offshore workers participating in the Basic Offshore Safety Induction and Emergency Training (BOSIET) and their success in the training and to examine the potential factors affecting anxiety. MATERIALS AND METHODS The trainees' state-anxiety values were determined using the State-Trait Anxiety Inventory (STAI) Form TX-1 before and after each exercise, and trait-anxiety values were determined using TX-2 after all exercises had been completed. RESULTS Among 276 trainees, female (n = 17), non-swimmers (n = 22) and younger trainees (median age: 35 [32-41]) had higher state-anxiety levels. The most anxiety-provoking and the most unsuccessful parts of the training were helicopter escape, the use of Compressed Air Emergency Breathing System (CA-EBS), and sea survival, respectively. After the CA-EBS exercise, where failure was seen for the first time, the anxiety level of those who failed increased. CONCLUSIONS The post-exercise state-anxiety scores of the unsuccessful ones were higher than those of the successful ones.

Abstract
PURPOSE Patients with vertical strabismus and consecutive diplopia due to Graves' orbitopathy (GO) might need recession of the rectus superior muscle. The aim of this retrospective analysis is to provide dose-effect values and motility analysis for these patients. METHODS Dose-effect relations (deviation reduction in primary position per amount of recession in mm), monocular excursions and size of the field of binocular single vision (BSV) were evaluated in three different groups of patients. Group 1 (n = 33) patients with primary fibrosis of superior rectus muscle undergoing recession of the ipsilateral rectus superior, Group 2 (n = 14) superior rectus muscle recession after recession of inferior rectus on the contralateral eye and Group 3 (n = 15) simultaneous ipsilateral superior rectus recession and contralateral inferior rectus muscle recession. Surgery was performed using the dose-effect for inferior rectus recession of 4 prism dioptre (PD,Δ ) reduction/per mm recession and the intraoperative traction test. RESULTS Restoration of BSV in the central 20° of gaze could be reached in 88%, 79% and 67% of patients in the three groups, respectively. Restoration of BSV in downgaze (up to 30°) was a little less successful, 79%, 57% and 53%, respectively. The median dose-effect was 3.2Δ reduction/mm recession in Group 1 (Spearman correlation r = 0.75, p < 0.0001) and 3.3Δ /mm in Group 2 (n.s.) and 4Δ /mm in Group 3 (r = 0.67, p = 0.016). The basis for the improvement was the symmetrization of ductions. CONCLUSION If superior rectus recession is necessary in GO, higher dosing around 3Δ reduction/per mm recession should be applied. In case of large deviations, combined vertical surgery (inferior rectus and superior rectus contralateral) is required and reasonable (low cyclotorsion). Single-step or two-step procedures lead to similar results.

Abstract
Objectives At present, the literature lacks data on the outcome of neurosurgery training programs in the Middle East. In this study we aim to assess the attrition, completion of training and success rates in the Saudi Board of Neurosurgery (SBNS). Methods A cohort of 115 trainees who started SBNS training during 2001-2014 was reviewed. The outcome was the rate of attrition, completion of training, and success in the final examination of the SBNS. Results Attrition rate was 29% (14% to neurosurgery training elsewhere and 15% to non-neurosurgery). Completion of training rate was 71%. Success in the final examination rate was 74% (60% on the first attempt). Attrition rate was significantly influenced by being sponsored by University Hospitals. Success rate was impacted positively by being sponsored by King Fahad Medical City and negatively by Ministry of Health Hospitals. Trainees who started during 2011-2014 had a significantly better success rate in the final examination. Conclusions SBNS attrition rate was high due to access to training opportunities abroad, particularly for university-sponsored trainees. Success rate in the final examination was considered comparable to some other neurosurgical qualifications. The first attempt pass rate was significantly impacted by being sponsored by certain hospitals. Factors contributing to attrition and failure should be identified and addressed during the selection process and during training.

Abstract
OBJECTIVE To investigate the impact of timing of implant placement and loading on implant survival and biological outcomes of multiple-unit implant-supported fixed dental prosthesis (FDPs). MATERIAL AND METHODS A literature search was performed by three independent reviewers for studies reporting on ≥10 patients with FPDs supported by ≥two implants over ≥3 years of follow-up. Data were analyzed on implant survival and biological complications as primary outcomes and biological events, including changes in peri-implant marginal bone level (MBL), probing depth, soft-tissue level, and health condition as secondary outcomes. RESULTS 7002 titles were identified, 360 full-texts were screened, and 14 studies were included. These comprised 6 randomized controlled studies (RCTs), 5 cohort studies, and 3 case series with identifiable implant placement and loading protocols in five of 09 possible combinations. All groups but one (IPIL) showed implant survival rates >90%. A meta-analysis based on 3 RCTs found no differences in survival rate between DPIL and DPDL (p = .227). CONCLUSIONS High survival rates for all studied implant placement and loading combinations were shown for FPDs over ≥3 years of follow-up. When a delayed implant placement protocol is applied, immediate or delayed loading demonstrated similar survival rates. The heterogeneity of the data did not allow to draw any further conclusions on the occurrence of biological complications related to timing of implant placement/loading.

Abstract
BACKGROUND A well-designed cancer control plan is an important tool for a nation, state, or community to address the burden of cancer. Furthermore, it provides the opportunity to devise and implement measurable objectives. However, there has been little to no assessment of the success rates of such objectives. METHODS I compared the success rate of objectives between US states' current plan and most recent past plan to determine the proportion of success in the United States overall. I also tested possible reasons for low success rates. RESULTS The mean success rate was 20% for stringent successes (only exact matches between plans) and 28% for loose successes (exact and similar matches between plans). The magnitude of change in percentage between the baseline and target for loose objectives significantly predicted success (P = .0347). Higher change resulted in lower success. However, neither the number of objectives nor the level of overlap significantly predicted success rate. Nor was population size, region, or rural-urban status significantly related to success rate. The most successful states had high proportions of objectives that were measurable and a high number of overlapping objectives. CONCLUSION I found that objective success rates were low for cancer control plans. To improve success rates, I suggest that future cancer control plans ensure each objective has a measurable baseline and realistically attainable target.

Abstract
Inoculation of embryonated chicken eggs has been widely used during the past decades; however, inoculation success rates have not been investigated systematically. In this study named success rates were assessed in brown eggs incubated between 5 and 19 days, which were inoculated with 0.2 ml methylene blue per egg. Inoculations were performed in a simple and fully standardized way. Five embryonic compartments were targeted blindly (amniotic cavity, embryo, allantoic cavity, albumen and yolk) with needles of four different lengths; albumen and yolk were targeted with eggs in upside down position. Three compartments were inoculated within sight (air chamber, chorioallantoic membrane and blood vessel). Twenty embryos were used per incubation day, intended deposition site and needle length. Success rates were assessed by visual inspection after breaking the eggs. The inoculations targeting albumen, yolk, amniotic cavity and embryo yielded low scores. Magnetic resonance imaging was performed to elucidate the reason(s) for these low success rates: needles used were of appropriate length, but embryo and amniotic cavity had variable positions in the eggs, while albumen and yolk rapidly changed position after turning the eggs upside down. The latter led to adjustment of the inoculation method for albumen and yolk. Failures to inoculate compartments within sight were immediately visible; therefore, these eggs could be discarded. Except for the amniotic cavity, full scores (20/20) were obtained for all compartments although not always on every day of incubation. In conclusion, the present study may serve as a guide to more accurately inoculate the various chicken embryo compartments. RESEARCH HIGHLIGHTS Blind inoculation of embryonated egg compartments was successful, except for the amniotic cavity. MRI showed rapid position change of albumen and yolk after turning eggs upside down. In ovo vaccination against Marek's disease might be improved by using 38 mm needles.

Abstract
RESEARCH QUESTION What was the utilization, effectiveness and safety of assisted reproductive techniques performed in Latin America during 2017. DESIGN Retrospective collection of multinational data on ART performed in 188 institutions from 15 Latin American countries. RESULTS We are reporting 93,600 initiated cycles, 16,976 deliveries and the birth of 20,404 babies. ART utilization was 221 cycles/million inhabitants (15 to 535). Despite women aged ≥40 represented 30.5% of fresh IVF/ICSI, after removing freeze-all cycles, delivery rate per oocyte retrieval was 19.9% for ICSI and 20.2% for IVF. Overall, single embryo transfer (SET) represented 26.9% of fresh transfers, with 18.2% delivery rate per transfer; increasing to 32.3% in elective SET. Delivery rate in double embryo transfers (DET) was 28.3% increasing to 37.3% with elective DET. This 5% increment in births in eDET over eSET resulted in10-fold increase in twin births, almost 3 weeks' shorter gestations and 3-fold increase in perinatal mortality. Delivery rate in frozen/thawed SET, reached 25.5% increasing to 30.8% with DET; the majority being blastocysts transfers. Of all births, 67% were singletons, 31.4% twins, and 1.6% triplets and higher. Overall, preterm deliveries reached 9.5% in singletons, 64.3% in twins and 97.9% in triplets; and perinatal mortality was 9.4‰ in singletons, 25.3‰ in twins, and 63.3‰ in high-order multiples. CONCLUSIONS The number of initiated cycles slowly increases. Frozen embryo transfers, blastocyst transfers and SET are also increasing. Our data shows that especially in young women and oocyte recipients, when there is more than one blastocyst for transfer, elective SET should be the rule.

Abstract
Describing clinical outcomes from assisted reproduction technology (ART) treatment cycles has been an evolving challenge throughout the world. Three simple metrics provide a transparent and highly accurate summary of ART outcomes. The first metric is the probability of having no embryos available to transfer. This metric incorporates all causes of failure from initiation of the treatment cycle up to the point immediately before actual embryo transfer. Patients will know what the risk is of failing, whether it is due to poor follicular stimulation, failed fertilization, poor embryo development, or abnormal preimplantation genetic testing for aneuploidy (PGT-A) results. The second and most important metric is sustained implantation rate: the probability that any transferred embryo will implant and progress to delivery. In the event of a single-embryo transfer, the metric is identical to delivery rate per transfer. By calculating per embryo, it provides a summary of the quality of outcomes within the program without the obscuring effect of multiple-embryo transfer. The final metric is the number of supernumerary embryos cryopreserved during the cycle. This speaks to the efficiency of the process by providing an estimate of potential benefits which may come from an additional transfer should the first one be unsuccessful or even to allow the couple to pursue an additional child without another full ART cycle. These metrics are easy to calculate and provide a detailed picture of the outcomes attained by the program.

Abstract
Background The objective was to explore the efficacy of ablation lesion sets in addition to pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation. The optimal strategy for catheter ablation of paroxysmal atrial fibrillation is debated. Methods and Results The SMASH‐AF (Systematic Review and Meta‐analysis of Ablation Strategy Heterogeneity in Atrial Fibrillation) study cohort includes trials and observational studies identified in PubMed, Scopus, and Cochrane databases from January 1 1990, to August 1, 2016. We included studies reporting single procedure paroxysmal atrial fibrillation ablation success rates. Exclusion criteria included insufficient reporting of outcomes, ablation strategies that were not prespecified and uniform, and a sample size of fewer than 40 patients. We analyzed lesion sets performed in addition to PVI (PVI plus) using multivariable random‐effects meta‐regression to control for patient, study, and procedure characteristics. The analysis included 145 total studies with 23 263 patients (PVI‐only cohort: 115 studies, 148 treatment arms, 16 500 patients; PVI plus cohort: 39 studies; 46 treatment arms, 6763 patients). PVI plus studies, as compared with PVI‐only studies, included younger patients (56.7 years versus 58.8 years, P=0.001), fewer women (27.2% versus 32.0% women, P=0.002), and were more methodologically rigorous with longer follow‐up (29.5 versus 17.1 months, P 0.004) and more randomization (19.4% versus 11.8%, P<0.001). In multivariable meta‐regression, PVI plus studies were associated with improved success (7.6% absolute improvement [95% CI, 2.6–12.5%]; P<0.01, I2=88%), specifically superior vena cava isolation (4 studies, 4 treatment arms, 1392 patients; 15.1% absolute improvement [95% CI, 2.3–27.9%]; P 0.02, I2=87%). However, residual heterogeneity was large. Conclusions Across the paroxysmal atrial fibrillation ablation literature, PVI plus ablation strategies were associated with incremental improvements in success rate. However, large residual heterogeneity complicates evidence synthesis.

Abstract
To determine antenatal factors that may predict successful vaginal birth after Caesarean section (VBAC), to develop a relevant antenatal scoring system and a nomogram for prediction of vaginal birth after caesarean delivery. A non recurring indication for previous Caesarean section (CS), such as breech presentation or foetal distress, is associated with a much higher successful VBAC rate than recurrent indications, such as cephalopelvic disproportion (CPD). Prior vaginal deliveries are excellent prognostic indicators of successful VBAC, especially if the vaginal delivery follows the prior CS. A low vertical uterine incision does not seem to adversely affect VBAC success rates as compared to a low transverse incision. Maternal obesity and diabetes mellitus adversely affect VBAC outcomes. Foetal macrosomia does not appear to be a contraindication to VBAC, as success rates exceeding 50% are achieved and uterine rupture rates are not increased. An inter-pregnancy interval of <24 months is not associated with a decreased success of VBAC. Success rates decrease when interval increases. Twin gestation does not preclude VBAC. Post-dates pregnancies may deliver successfully by VBAC in greater than two-thirds of cases. There are few absolute contraindications to attempted VBAC. Attempted VBAC will be successful in the majority of attempted cases.

Abstract
In clinical studies, we often compare the success rates of two treatment groups where post-treatment responses of subjects within clusters are usually correlated. To estimate the difference between the success rates, interval estimation procedures that do not account for this intraclass correlation are likely inappropriate. To address this issue, we propose three interval procedures by direct extensions of recently proposed methods for independent binary data based on the concepts of design effect and effective sample size used in sample surveys. Each of them is then evaluated with four competing variance estimates. We also extend three existing methods recommended for complex survey data using different weighting schemes required for those three existing methods. An extensive simulation study is conducted for the purposes of evaluating and comparing the performance of the proposed methods in terms of coverage and expected width. The interval estimation procedures are illustrated using three examples in clinical and social science studies. Our analytic arguments and numerical studies suggest that the methods proposed in this work may be useful in clustered data analyses.

Abstract
PURPOSE The primary objective of this systematic review was to compare treatment outcomes of direct and indirect permanent restorations in endodontically treated teeth, and provide clinical suggestions for restoring teeth after endodontic treatment. MATERIALS AND METHODS Electronic databases (Medline, EMBASE, CENTRAL) and gray literature were screened for articles in English that reported on prospective and retrospective clinical studies of direct or indirect restorations after endodontic treatment with an observation period of at least 3 years. Primary outcomes were determined to be short-term (≤ 5 years) and medium-term (> 5 and ≤ 10 years) survival. Secondary outcomes included restorative and endodontic success of restored teeth. The quality of included studies and risk of bias were assessed using Cochrane Collaboration's tool for RCTs (randomized controlled trials), the Newcastle-Ottawa Scale for cohort studies, and the Agency for Healthcare Research and Quality (AHRQ) methodology checklist for cross-sectional studies. The GRADE system was used for assessing collective strength of the overall body of evidence. RESULTS Of 2547 screened articles, only 9 (2 RCTs, 3 retrospective cohort studies, 3 cross-sectional studies) met the inclusion criteria, and 8 studies were used in the meta-analysis. In general, indirect restorations (mostly full crowns) showed higher 5-year survival (OR 0.28, 95% CI 0.19-0.43, p < 0.00001) and 10-year survival (OR 0.20, 95% CI 0.12-0.31, p < 0.00001) than direct restorations. However, there was no statistical difference in short-term (≤ 5-years) restorative success (OR 0.32, 95% CI 0.05-2.12, p = 0.24) and endodontic success (OR 0.88, 95% CI 0.72-1.08, p = 0.22). CONCLUSIONS Based on current evidence, there is a weak recommendation for indirect restorations to restore endodontically treated teeth, especially for teeth with extensive coronal damage. Indirect restorations using mostly crowns have higher short-term (5-year) and medium-term (10-year) survival than do direct restorations using composite or amalgam (GRADE quality of evidence: low to moderate), but no difference in short-term (≤ 5 years) restorative success (low quality) and endodontic success (very low quality). There is a need for high-quality clinical trials, especially well-designed RCTs.

Abstract
For the past 10 years, the annual 'Antibodies to watch' articles have provided updates on key events in the late-stage development of antibody therapeutics, such as first regulatory review or approval, that occurred in the year before publication or were anticipated to occur during the year of publication. To commemorate the 10th anniversary of the article series and to celebrate the 2018 Nobel Prizes in Chemistry and in Physiology or Medicine, which were given for work that is highly relevant to antibody therapeutics research and development, we expanded the scope of the data presented to include an overview of all commercial clinical development of antibody therapeutics and approval success rates for this class of molecules. Our data indicate that: 1) antibody therapeutics are entering clinical study, and being approved, in record numbers; 2) the commercial pipeline is robust, with over 570 antibody therapeutics at various clinical phases, including 62 in late-stage clinical studies; and 3) Phase 1 to approval success rates are favorable, ranging from 17-25%, depending on the therapeutic area (cancer vs. non-cancer). In 2018, a record number (12) of antibodies (erenumab (Aimovig), fremanezumab (Ajovy), galcanezumab (Emgality), burosumab (Crysvita), lanadelumab (Takhzyro), caplacizumab (Cablivi), mogamulizumab (Poteligeo), moxetumomab pasudodox (Lumoxiti), cemiplimab (Libtayo), ibalizumab (Trogarzo), tildrakizumab (Ilumetri, Ilumya), emapalumab (Gamifant)) that treat a wide variety of diseases were granted a first approval in either the European Union (EU) or United States (US). As of November 2018, 4 antibody therapeutics (sacituzumab govitecan, ravulizumab, risankizumab, romosozumab) were being considered for their first marketing approval in the EU or US, and an additional 3 antibody therapeutics developed by Chinese companies (tislelizumab, sintilimab, camrelizumab) were in regulatory review in China. In addition, our data show that 3 product candidates (leronlimab, brolucizumab, polatuzumab vedotin) may enter regulatory review by the end of 2018, and at least 12 (eptinezumab, teprotumumab, crizanlizumab, satralizumab, tanezumab, isatuximab, spartalizumab, MOR208, oportuzumab monatox, TSR-042, enfortumab vedotin, ublituximab) may enter regulatory review in 2019. Finally, we found that approximately half (18 of 33) of the late-stage pipeline of antibody therapeutics for cancer are immune checkpoint modulators or antibody-drug conjugates. Of these, 7 (tremelimumab, spartalizumab, BCD-100, omburtamab, mirvetuximab soravtansine, trastuzumab duocarmazine, and depatuxizumab mafodotin) are being evaluated in clinical studies with primary completion dates in late 2018 and in 2019, and are thus 'antibodies to watch'. We look forward to documenting progress made with these and other 'antibodies to watch' in the next installment of this article series.

Abstract
Recent advances in embryo freezing technology together with growing concerns over multiple births have shifted the paradigm of appropriate IVF. This has led to the adoption of new performance indicators for ART clinics by national reporting schemes, such as those curated by the Society for Assisted Reproductive Technology (SART) and the Human Fertilization and Embryology Authority (HFEA). Using these organizations as case studies, we review several outcome measures from a statistical perspective. We describe several denominators that are used to calculate live birth rates. These include cumulative birth rates calculated from all fresh and frozen transfer procedures arising from a particular egg collection or cycle initiation, and live birth rates calculated per embryo transferred. Using data from both schemes, we argue that all cycles should be included in the denominator, regardless of whether or not egg collection and fertilization were successful. Excluding cancelled cycles reduces the impact of confounding due to patient characteristics but also removes policy and performance differences which we argue represent relevant sources of variation. It may be misleading to present prospective patients with essentially hypothetical measures of performance predicated on parity of ovarian stimulation and transfer policies. Although live birth per embryo has the advantage of encouraging single embryo transfer, we argue that it is prone to misinterpretation. This is because the likelihood of live birth is not proportional to the number of embryos transferred. We conclude that it is not possible to present a single measure that encompasses both effectiveness and safety. Instead, we propose that a set of clear, relevant outcome indicators is necessary to enable subfertile patients to make informed choices regarding whether and where to be treated.

Abstract
OBJECTIVES To establish how medically assisted reproduction (MAR) clinics report success rates on their websites. SETTING Websites of private and NHS clinics offering in vitro fertilisation (IVF) in the UK. PARTICIPANTS We identified clinics offering IVF using the Choose a Fertility Clinic facility on the website of the Human Fertilisation and Embryology Authority (HFEA). Of 81 clinics identified, a website could not be found for 2, leaving 79 for inclusion in the analysis. PRIMARY AND SECONDARY OUTCOME MEASURES Outcome measures reported by clinic websites. The numerator and denominator included in the outcome measure were of interest. RESULTS 53 (67%) websites reported their performance using 51 different outcome measures. It was most common to report pregnancy (83% of these clinics) or live birth rates (51%). 31 different ways of reporting pregnancy and 9 different ways of reporting live birth were identified. 11 (21%) reported multiple birth or pregnancy rates. 1 clinic provided information on adverse events. It was usual for clinics to present results without relevant contextual information such as sample size, reporting period, the characteristics of patients and particular details of treatments. CONCLUSIONS Many combinations of numerator and denominator are available for the purpose of reporting success rates for MAR. The range of reporting options available to clinics is further increased by the possibility of presenting results for subgroups of patients and for different time periods. Given the status of these websites as advertisements to patients, the risk of selective reporting is considerable. Binding guidance is required to ensure consistent, informative reporting.

Abstract
Background: Patients increasingly use the internet as a source of medical information before initial contact with doctors and during treatment. This applies to reproductive medicine too, where the internet could offer patients the chance to inform themselves in advance about specific procedures and the treatment centres that offer them. In this way it could potentially contribute to informed patient decision-making. This article analyses the web presence of German fertility treatment centres with respect to the provision of information on success rates, risks and side effects of treatment. Methods: Analysis of published success rates and information on the risks and adverse effects of IVF and related methods on German IVF centre websites. Results: Over half of the 129 centres (62.02 %) state a general success rate or their own institution's success rate. Less than a quarter (24.03 %) states their own institution's pregnancy rate and only 7.75 % their own birth rate. The published success rates are mostly pregnancy rates (pregnancy per embryo transfer), which by definition are higher than baby take-home-rates creating unrealistic expectations. Only 61 centres (47.29 %) mention risks and side effects of the procedures offered, and that in varying detail. Only 7 centres (5.43 %) provide information on the risk of psychological stress associated with unsuccessful fertility treatment. Conclusion: There is insufficient opportunity for women and their partners to inform themselves adequately on the internet in advance of treatment about available treatment methods, their success rates and associated risks/side effects; this applies both to specific facilities as well as to the procedures in general. In contrast to other countries, in Germany there is a lack of discussion on content requirements for fertility treatment facility websites.

Abstract
We examined the application and review materials of three calls (n=2,823) of a prestigious grant for personal research funding in a national full population of early career scientists awarded by the Netherlands Organization for Scientific Research (NWO). Results showed evidence of gender bias in application evaluations and success rates, as well as in language use in instructions and evaluation sheets. Male applicants received significantly more competitive "quality of researcher" evaluations (but not "quality of proposal" evaluations) and had significantly higher application success rates than female applicants. Gender disparities were most prevalent in scientific disciplines with the highest number of applications and with equal gender distribution among the applicants (i.e., life sciences and social sciences). Moreover, content analyses of the instructional and evaluation materials revealed the use of gendered language favoring male applicants. Overall, our data reveal a 4% "loss" of women during the grant review procedure, and illustrate the perpetuation of the funding gap, which contributes to the underrepresentation of women in academia.

Abstract
AIM To demonstrate that success rates with in vitro fertilisation (IVF) have been improving despite decreasing the number of embryos transferred. MATERIALS AND METHODS This was a retrospective cohort study comparing live birth outcomes for women who started IVF between 2001 and 2005 with women who started between 2006 and 2010, using life table analysis to allow for the fact that women had differing number of cycles of treatment. The data were obtained from a single IVF centre, Monash IVF Geelong, Victoria. The 2001-2005 cohort consisted of 233 women, and the 2006-2010 cohort consisted of 453 women who started IVF between the specified dates. The main outcome measure was a live birth. Life table analysis was used to estimate the cumulative probability of a live birth after each cycle. RESULTS The estimate of cumulative live birth probability demonstrated that the chance of a live birth by cycle five was 75.8% in the 2001-2005 cohort, which significantly increased to 80.1% by cycle five in the 2006-2010 cohort (P = <0.05). There was a mean of 1.8 embryos transferred per embryo transfer in the 2001-2005 cohort, which decreased to a mean of 1.3 embryos transferred per embryo transfer in the 2006-2010 cohort. This was associated with a significant decrease in the multiple birth rate from 24.7% in the 2001-2005 cohort to 7.5% in the 2006-2010 cohort. CONCLUSION The IVF success rate has significantly improved despite the number of embryos transferred being reduced. This study provides further support for elective single embryo transfers.

Abstract
Aim To examine the success rates of emergency department airway management by resident physicians in Japan. Methods We conducted an analysis of a multicentre prospective registry (Japanese Emergency Airway Network Registry) of 13 academic and community emergency departments in Japan. We included all patients who underwent emergency intubation performed by postgraduate year 1 to 5 transitional or emergency medicine residents (resident physicians) between April 2010 and August 2012. Outcome measures were success rates by the first intubator, and by rescue intubator, according to the level of training. Results We recorded 4,094 intubations (capture rate, 96%); 2,800 attempts (2,800/4,094; 68%; 95% confidence interval (CI), 67%-70%) were initially performed by resident physicians. Overall success rate on the first attempt was 63% (1,767/2,789; 95%CI, 61%-64%); the rate improved over the first 3 years of training before reaching a plateau (P trend < 0.001). Success rate by the first intubator was 78% (2,185/2,800; 95%CI, 76%-79%); the rate steadily improved as level of training increased (P trend < 0.001). Of 597 failed intubation attempts by the first intubator, 41% (247/597; 95%CI, 37%-45%) of rescue attempts were performed by resident physicians. Success rate on the first rescue attempt was 76% (187/247; 95%CI, 70%-81%), and success rate by first rescue intubator was 89% (220/247; 95%CI, 85%-93%). These rates on rescue attempts steadily improved as level of training increased (both P trend < 0.001). Intubations were ultimately successful in 2,778 encounters (99.6%). Conclusion In this multicentre study characterizing emergency airway management across Japan, we observed that emergency department intubations were primarily managed by resident physicians with acceptably high success rates overall.

Abstract
OBJECTIVE To use a large and recent national registry to provide an updated report on the effect of recipient age on the outcome of donor oocyte in vitro fertilization (IVF) cycles. DESIGN Retrospective cohort study. SETTING United States national registry for assisted reproductive technology. PATIENT(S) Recipients of donor oocyte treatment cycles between 2008 and 2010, with cycles segregated into five age cohorts: ≤34, 35 to 39, 40 to 44, 45 to 49, and ≥50 years. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Implantation, clinical pregnancy, live-birth, and miscarriage rates. RESULT(S) In donor oocyte IVF cycles, all age cohorts ≤39 years had similar rates of implantation, clinical pregnancy, and live birth when compared with the 40- to 44-year-old reference group. Patients in the two oldest age groups (45 to 49, ≥50 years) experienced statistically significantly lower rates of implantation, clinical pregnancy, and live birth compared with the reference group. Additionally, all outcomes in the ≥50-year-old group were statistically significantly worse than the 45- to 49-year-old group, demonstrating progressive decline with advancing age. CONCLUSION(S) Recent national registry data suggest that donor oocyte recipients have stable rates of pregnancy outcomes before age 45, after which there is a small but steady and significant decline.
