Abstract
BACKGROUND Indigenous nursing students contended with far-reaching challenges during the pandemic that significantly altered their experiences of nursing education. These experiences are poorly understood by nursing educators and strategies for Indigenous nursing student success rarely involve the insights of current Indigenous nursing students. AIM The aim of this article is to offer Indigenous-student derived recommendations regarding strategies for improving their experiences and success within nursing education during the pandemic and beyond. DESIGN AND METHODS This qualitative study employed an Indigenous methodology including land-based learning, ceremony, and sharing circles. PARTICIPANTS AND SETTING Indigenous nursing students (n = 17) from a Western Canadian school of nursing participated in one of three sharing circles. RESULTS Indigenous nursing students recommended institutional and program adaptations along with increases to cultural safety for enhancing their experience in nursing education. Institutional and program strategies included: decreasing course loads and class sizes; an Indigenous-specific cohort; a transition program after course failure; increasing academic supports such as additional clinical skills and academic writing practice. Recommendations for increasing cultural safety included: mandatory and recurrent cultural safety training for faculty, staff and students; differential learning and evaluation strategies; and increased inclusion of Indigenous ceremonies and practices. CONCLUSION The findings of this study provide insights that can help guide curriculum development, pedagogical approaches, and policy development to improve nursing education for Indigenous students.

Abstract
INTRODUCTION This retrospective cohort study aimed to evaluate long-term healing outcomes (10-17.5 years) following contemporary endodontic microsurgery (EMS) and identify associated prognostic factors. METHODS Clinical and radiographic data of an EMS cohort (2006-2013) from the electronic data base of Dental Hospital were reviewed retrospectively by two independent examiners to determine their survival and healing outcomes, and potential prognostic factors analyzed by Cox proportional hazards regression and logistic regression (α = 0.05). RESULTS Through strict inclusion and exclusion criteria, and 721 EMS-treated teeth in the cohort, 309 (42.9%) were included (male, 35.0%; female, 65.0%; age, 45.83 ± 15.53 years) with mean final follow-up of 152.26 ± 26.37 months (range, 120-211; median, 148). Clinical and radiographic assessments found 80.5% of 10 years survival rate with 63.4% of success. Collectively, tooth type, tooth mobility, preoperative lesion size, clinical crown-root ratio, and crown restorations at follow-up were significantly associated with long-term success and survival over 10 years. CONCLUSIONS The preoperative status and condition of the tooth including its alveolar bone support, and adequate full crown restorations may be relevant prognostic determinants of success and survival following EMS over time.

Abstract
Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback (NF), a training method for the self-regulation of brain activity, has shown promising results as a neurorehabilitation tool, depending on the ability of the patient to succeed in neuromodulation. This study explores connectivity-based structural and functional success predictors in an NF n-back working memory paradigm targeting the dorsolateral prefrontal cortex (DLPFC). We established as the NF success metric the linear trend on the ability to modulate the target region during NF runs and performed a linear regression model considering structural and functional connectivity (intrinsic and seed-based) metrics. We found a positive correlation between NF success and the default mode network (DMN) intrinsic functional connectivity and a negative correlation with the DLPFC-precuneus connectivity during the 2-back condition, indicating that success is associated with larger uncoupling between DMN and the executive network. Regarding structural connectivity, the salience network emerges as the main contributor to success. Both functional and structural classification models showed good performance with 77% and 86% accuracy, respectively. Dynamic switching between DMN, salience network and central executive network seems to be the key for neurofeedback success, independently indicated by functional connectivity on the localizer run and structural connectivity data.

Abstract
Despite the high success rates reported in head and neck reconstruction, free flap failures continue to persist. Understanding the factors associated with flap loss and improving overall success are paramount. This study aimed to comprehensively assess the factors influencing flap revision and free tissue transfer survival in head and neck reconstruction. The study included 70 patients with defects in the lower two-thirds of the head and neck region and underwent reconstruction using free flaps. Patient age, gender, smoking status, comorbidities and data on the location and aetiology of the defect, the specific type of flap employed, the recipient artery and vein chosen, instances of revision and the overall success of the flap were collected. The investigation aimed to establish correlations between these variables as well as flap success and revision rates. No statistically significant differences were observed in arterial and venous anastomosis revision rates, or flap survival, in relation to variables such as age, gender, flap type, smoking status, comorbidities, recipient artery or vein and the number of vein anastomoses. The malignant tumour group exhibited a lower requirement for arterial revision and a higher flap survival rate compared to the benign tumour group. This study underscores the comparable safety profiles of perforator-based and conventional flaps in head and neck reconstruction. Furthermore, it reveals that patient characteristics are not contraindications for free tissue transfer. Additionally, the quantity of the veins and choice of recipient vessels are flexible and do not significantly impact flap success. The higher rates of flap success in patients with malignant aetiology requires further investigation.

Abstract
Multicenter studies play a crucial role in medical research and advancement, facilitating the application of new knowledge to clinical practice. These studies are associated with multiple benefits but are more complex than those involving a single center. With the philosophy that most of the qualities required to lead a multicenter study depend on attitude and can be learned, developed, and improved, in this manuscript, we share with the reader a series of recommendations that we consider important for successfully conducting such studies. The tips and tricks that will be discussed in detail are as follows: effectively leading the project; clearly defining viable and relevant objectives; designing a clear and detailed protocol; carefully selecting centers and collaborating investigators; meticulously designing the case report form; centrally managing the project efficiently; maintaining fluent communication with investigators; and, finally, designing a clear authorship policy and ensuring the appropriate publication of the study results. We hope that these suggestions encourage potential researchers to conduct multicenter studies, thereby collectively enhancing the quality of research and its application to clinical practice.

Abstract
The objective of this study was to assess the effect of two different strength-training methods on both male and female water polo players' performance and shoulder pain. The players were randomly allocated to a maximum strength (MS: 14 males, 8 females) or power strength (PS: 13 males, 8 females) training group. Before and after the intervention, we assessed player's anthropometric characteristics, shoulder internal and external rotation strength, hand grip strength, upper body strength, countermovement jump height, throwing velocity, swimming speed, shoulder pain on a visual analogue scale (VAS), wellness, and rate of perceived exertion per session. We observed no significant improvement (P<0.05) in specific skills but enhancement in hand grip strength in male players. In female players in the MS group, throwing speed and bench press weight decreased significantly (P<0.05). Shoulder external rotation strength at 240°/sec in male MS group players and shoulder external rotation strength at 60°/sec in female PS group players decreased significantly (P<0.05). In addition, from the first to the last week, shoulder pain increased significantly (P<0.05) in all players. Inverse correlations (P<0.05) were found between VAS and shoulder rotation strength in males in the PS group, and between wellness and shoulder internal rotation strength in men in the MS group and women in the PS group. We found that both MS and PS training did not enhance performance and increased shoulder pain in male and female water polo players.

Abstract
Expert players in throwing sports may reduce the variability of projectile arrival position by systematically relating release parameters (e.g., release position, velocity, and angular velocity of the projectile). Reducing the variability of the projectile arrival position is often believed to increase the success rate of throwing task, but it may not be always true. Here, we experimentally illustrate that the systematic relationship between release parameters that reduce the variability of the ball arrival position may not increase the number of hitting trials during a throwing task. Furthermore, we demonstrate that the role of the release parameters in increasing successful trials can vary depending on the target size. Each participant threw balls at two different-sized targets (small and large target conditions). Additionally, they alternately threw balls with overhead and sidearm throwing for both the small and large targets. Our results showed that the release position and velocity in the left-right direction reduced the variability of the ball arrival position and increased the successful trials in the small target condition. In the large target condition, the two release parameters reduced the variability of the ball arrival position, but they did not increase the successful trials. Consequently, reducing the variability of the ball arrival position did not always equate to an increase in successful trials, as it depended on the target size. These findings indicate that the role of the release parameters in increasing hitting trials is not constant but varies depending on the condition of the motor task.

Abstract
BACKGROUND Kidney transplantation is considered an ideal treatment for end-stage renal disease (ESRD) because it provides a longer and better quality of life than dialysis. ABO-incompatible (ABO-I) kidney transplantation relies on two principles: (i) removal of antibodies from a blood group; and (ii) inhibition of reappearance of blood group antibodies by intensifying the induction and maintenance of immunosuppression. This systematic review aimed to analyze the success and safety of ABO-I live-donor kidney transplantation. METHODS Databases, including Google Scholar, PubMed, Embase, Web of Science, and Medline were searched. Search duration was from the database establishment to December 2022. A thorough search was performed for relevant studies investigating the success and safety of ABO-I live-donor kidney transplantation. Two investigators independently extracted literature information and assessed the quality of the included studies. Heterogeneity test was performed using Cochrane's Q and chi-squared tests. All statistical analyses were performed using R software (version 4.2.1). RESULTS The search for relevant literature in the five electronic databases yielded 1238 articles. Of the 1238 articles, only 15 were included. Meta-analysis of outcomes from five studies showed a survival rate of 0.93 (95% confidence interval [CI]: 0.88 to 0.97, P < 0.001) after ≥3 years, while outcomes from 12 studies revealed a short-term patient survival rate of 0.94 (95% CI: 0.92 to 0.96, P = 0.75). In contrast, long- and short-term graft survival rates were 0.89 (95% CI: 0.75 to 0.96, P < 0.001) and 0.94 (95% CI: 0.90 to 0.97, P < 0.001), respectively. Incidence rates of infectious, surgical, and medical complications were 0.31 (95% CI: 0.22 to 0.41, P < 0.001), 0.12 (95% CI: 0.05 to 0.25, P < 0.001), and 0.38 (95% CI: 0.17 to 0.66, P < 0.001), respectively. CONCLUSION Good long- and short-term patient outcomes and graft survival rates were observed after ABO-I kidney transplantation. Similarly, the safety of performing kidney transplantations from living donors with ABO-I blood groups was established by the results of the current meta-analysis. Therefore, ABO-I live-donor kidney transplantations should be encouraged to reduce the time recipients spend on waiting lists and supplement the existing paired-exchange donor program.

Abstract
BACKGROUND To improve knowledge on endoscopic retrograde cholangiopancreatography (ERCP) in children, we aimed to study the proportion of indications, success rate and complication of ERCP. METHODS We performed a systematic search of all articles published up to December 2022 in the following databases: Cochrane Library, PubMed (MEDLINE) and Scopus. The meta-analysis was performed using a random-effects model. Heterogeneity was determined by the I2 statistics and the Cochrane Q test. The included data were analyzed to identify the proportion of indications, success rate and complications of ERCP in children. RESULTS Based on data from 52 studies with a total of 5624 participants, the most common indications for ERCP in children were biliary [48% (95% CI: 0.40 - 0.57; I2 = 98.17%, P < 0.001)] and both biliary and pancreatic [41% (95% CI: 0.33 - 0.49; I2 = 98.27%, P < 0.001)]. The success rate of ERCP was 95% (95% CI: 0.94 - 0.96; I2 = 82.53%, P < 0.001) with the overall complication rate of 7% (95% CI: 0.05 - 0.09; I2 = 82.06%, P < 0.001). The pooled estimate for the incidence of post ERCP pancreatitis was 4% (95% CI: 0.03 - 0.06; I2 = 85.46%, P < 0.001) and the bleeding was 0% (95% CI: 0.0 - 0.0; I2 = 28.21%, P = 0.03). CONCLUSIONS ERCP appears to be performed safely in children with a similar success rate as in the adult population.

Abstract
INTRODUCTION Recovery of kidney function to liberate patients from acute kidney replacement therapy (AKRT) is recognized as a vital patient-centered outcome. The lack of specific guidelines providing specific recommendations on therapy interruption is an important obstacle. We aimed to determine the prevalence of successful discontinuation of AKRT and its predictive factors after the elaboration of clinical protocol with these recommendations. METHODOLOGY A prospective cohort study was performed with 156 patients at a public Brazilian university hospital between July 2020 and July 2021. RESULTS Success and hospital discharge were achieved for most patients (84.6% and 89%, respectively). Multivariable logistic regression analysis showed that C-reactive protein (CRP), urine output, and creatinine clearance at the time of interruption were variables associated with discontinuation success (OR: 0.943, CI: 0.905-0.983, p = 0.006; OR: 1.078, CI: 1.008-1.173, p = 0.009 and OR: 1.091, CI: 1.012-1.213, p = 0.004; respectively). The areas under the curve for CRP, urine output, and creatinine clearance at the time of interruption were 0.78, 0.62, and 0.82, respectively. Both CRP and creatinine clearance were good predictors of successful liberation of AKRT. The optimal cutoff value of them had sensitivity and specificity of 0.88 and 0.87, 0.91 and 0.90, respectively. The use of noradrenalin at the time of interruption (OR: 0.143, CI: 0.047-0.441, p = 0.001) and successful discontinuation (OR: 3.745, CI: 1.047-13.393, p = 0.042) were identified as variables associated with hospital discharge. CONCLUSION Our results show the factors related to success in discontinuing AKRT are the CRP, creatinine clearances, and urinary output at the time of AKRT interruption and it was associated with lower mortality.

Abstract
INTRODUCTION AND HYPOTHESIS This manuscript of Chapter 4 of the International Urogynecological Consultation (IUC) on Pelvic Organ Prolapse (POP) reviews the literature and makes recommendations on the definition of success in the surgical treatment of pelvic organ prolapse. METHODS An international group containing seven urogynecologists performed an exhaustive search of the literature using two PubMed searches and using PICO methodology. The first search was from 01/01/2012-06/12/2022. A second search from inception to 7/24/2022 was done to access older references. Publications were eliminated if not relevant to the clinical definition of surgical success for the treatment of POP. All abstracts were reviewed for inclusion and any disagreements were adjudicated by majority consensus of the writing group. The resulting list of articles were used to inform a comprehensive review and creation of the definition of success in the surgical treatment of POP. OUTCOMES The original search yielded 12,161 references of which 45 were used by the writing group. Ultimately, 68 references are included in the manuscript. For research purposes, surgical success should be primarily defined by the absence of bothersome patient bulge symptoms or retreatment for POP and a time frame of at least 12 months follow-up should be used. Secondary outcomes, including anatomic measures of POP and related pelvic floor symptoms, should not contribute to a definition of success or failure. For clinical practice, surgical success should primarily be defined as the absence of bothersome patient bulge symptoms. Surgeons may consider using PASS (patient acceptable symptom state) or patient goal attainment assessments, and patients should be followed for a minimum of at least one encounter at 6-12 weeks post-operatively. For surgeries involving mesh longer-term follow-up is recommended.

Abstract
AIMS Left bundle branch area pacing (LBBAP) is most often delivered using lumenless leads (LLLs), but may also be performed using stylet-driven leads (SDLs). There are limited reports on the comparison of these tools, mainly limited to reports describing initial operator experience or without detailed procedural data. Our aim was to perform an in-depth comparison of SDLs and LLLs for LBBAP at implantation and follow-up in a larger cohort of patients with experience that extends beyond that of the initial learning curve. METHODS AND RESULTS A total of 306 consecutive patients (age 77 ± 11 years, 183 males) undergoing LBBAP implantation at a single centre were prospectively included. The population was split into two groups of 153 patients based on the initial use of an SDL (from 4 manufacturers) or an LLL. After having discounted the initial learning curve of 50 patients, there was no difference in the success rate between the initial use of lead type (96.0% with SDL vs. 94.3% with LLL, P = 0.56). There were no significant differences in success between lead models. Electrocardiogram and electrical parameters were comparable between the groups. Post-operative macro-dislodgement occurred in 4.3% of patients (essentially within the first day following implantation) and presumed micro-dislodgement with loss of conduction system capture or rise in threshold (occurring mostly during the first month) was observed in 4.7% of patients, without differences between groups. CONCLUSION Left bundle branch area pacing may be safely and effectively performed using either LLLs or SDLs, which provides implanters with alternatives for delivering this therapy.

Abstract
Successful businesswomen in dermatology know what type of practice they want and create a plan to make it happen. They align their business with their life and surround themselves with people who support their goals. They accept support but know how to delegate. They do the hard work required to be successful, gaining knowledge and strength from the experience. When they make mistakes, they learn from them. They try to make the most of each patient's experience, while acknowledging that relationships with family, friends, and colleagues, as well as personal growth, are of utmost significance outside of their practices.

Abstract
This study aimed to report a multicentric national experience about the outcomes of pediatric endoscopic pilonidal sinus treatment (PEPSiT). The medical records of all pediatric patients, aged up to 18 years, who underwent PEPSiT in the period 2019-2021, were retrospectively reviewed. Patients' demographics, operative details, and post-operative outcomes were assessed. A total of 294 patients (182 boys), with median age of 14 years (range 10-18), receiving PEPSiT in the study period, were enrolled. Pilonidal sinus disease (PSD) was primary in 258 (87.8%) and recurrent in 36 (12.2%). The median operative time was 36 min (range 11-120). The median VAS pain score was 0.86 (range 0-3) and the median duration of analgesic use was 27 h (range 12-60). The overall success rate was 95.2% (280/294) and the median time to full healing was 23.4 days (range 19-50). Six/294 (2.0%) patients developed Clavien 2 post-operative complications. The recurrence rate was 4.8% (14/294) and all recurrences were re-operated using PEPSiT. Redo-surgery for wound debridement was performed in one (0.3%) patient with late healing. On multivariate analysis, hirsutism and typology of sinus (pits ≥ 2, paramedian and more proximal to the anus) were predictors of PSD recurrence (p = 0.001). To date, this is the largest series of PEPSiT published in the pediatric population. The outcomes reported after a 3 years experience confirm that PEPSiT is a safe, effective, and real minimally invasive procedure to treat adolescents with PSD. It provides patients quick and painless recovery, satisfactory success, and high quality of life.

Abstract
OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) infections impose a considerable burden on health systems, yet there is remarkable variation in the global incidence and epidemiology of MRSA. The MACOTRA consortium aimed to identify bacterial markers of epidemic success of MRSA isolates in Europe using a representative MRSA collection originating from France, the Netherlands and the United Kingdom. METHODS Operational definitions of success were defined in consortium meetings to compose a balanced strain collection of successful and sporadic MRSA isolates. Isolates were subjected to antimicrobial susceptibility testing and whole-genome sequencing; genes were identified and phylogenetic trees constructed. Markers of epidemiological success were identified using genome-based time-scaled haplotypic density analysis and linear regression. Antimicrobial usage data from ESAC-Net was compared with national MRSA incidence data. RESULTS Heterogeneity of MRSA isolate collections across countries hampered the use of a unified operational definition of success; therefore, country-specific approaches were used to establish the MACOTRA strain collection. Phenotypic antimicrobial resistance varied within related MRSA populations and across countries. In time-scaled haplotypic density analysis, fluoroquinolone, macrolide and mupirocin resistance were associated with MRSA success, whereas gentamicin, rifampicin and trimethoprim resistance were associated with sporadicity. Usage of antimicrobials across 29 European countries varied substantially, and β-lactam, fluoroquinolone, macrolide and aminoglycoside use correlated with MRSA incidence. DISCUSSION Our results are the strongest yet to associate MRSA antibiotic resistance profiles and antibiotic usage with the incidence of infection and successful clonal spread, which varied by country. Harmonized isolate collection, typing, resistance profiling and alignment with antimicrobial usage over time will aid comparisons and further support country-specific interventions to reduce MRSA burden.

Abstract
CONTEXT Early sport specialization is a growing concern among youth sports athletes, particularly in baseball. Motivation to participate in sports is an important factor in determining which sports youth athletes participate in and why. OBJECTIVE The purpose of this study was to qualitatively investigate youth sport participation behaviors and motivations of college baseball players. DESIGN Qualitative Study. SETTING Online Teleconference. PATIENTS OR OTHER PARTICIPANTS We conducted 25 semi-structured interviews with college baseball athletes who were classified as either high-level (n=8), moderate-level (n=9), or low-level specialists (n=8) prior to college. DATA COLLECTION AND ANALYSIS Participants completed an individual semi-structured interview to develop an understanding of the participants' youth and high school sports experiences and associated motivations to participate in those experiences. A framework analysis approach was used to analyze transcript data to identify themes among the three specialization groups. RESULTS From our interview analysis, six overall themes emerged among the groups: (1) Motivation, (2) Stress, (3) Quitting, (4) Barriers, (5) Facilitators of Success, and (6) Future Directions. Moderate and high-level specialists described higher levels of passion, participating in deliberate practice, higher levels of performance-related stress, and a desire to quit sports more than low-level specialists. None of the groups described parents as an overbearing external motivator to participate in sports at an early age. CONCLUSIONS Participants who were classified as low-, moderate-, and high-level specialists described different experiences related to their motivation, stress levels, desire to quit, barriers to participating in baseball, facilitators of success, and their overall future career goals after completing baseball. This information may be useful for parents, coaches, and health care professionals to better communicate the benefits and risks associated with sport specialization to youth athletes. Future research is needed to determine if differences in motivation levels exist in younger populations.

Abstract
BACKGROUND It is difficult to select patients who will benefit from endobronchial treatment (ET) in malignant central airway obstruction (MCAO). We aimed to determine the tumor-related factors that affect the success of MCAO treatment. METHODS ETs for MCAO between March 2019 and June 2021 were analyzed retrospectively. The relationships between the success of the procedure and the percentage of endoluminal obstruction, tumor size, and type of lesion were evaluated. RESULTS Totally, 220 ETs were administered to 205 patients. Treatment was significantly more successful for the patients with pure endobronchial lesions than those with mixed lesions. The success rate was significantly lower when the tumor size was greater than 54.5 mm and the degree of endoluminal stenosis exceeded 92%; the area under the curve was 0.734 (0.625-0.842; P=0.001) and 0.733 (0.597- 0.870; P=0.001), respectively. There was no difference in the procedural success between lung cancer and extrathoracic malignancies and tumor treatment before the procedure. CONCLUSION Mixed lesions, tumor size over 54.5 mm, and a degree of stenosis over 92% are risk factors for unsuccessful endoluminal obstruction procedures. These parameters should be considered when selecting patients for ET interventions.

Abstract
In today's education, student success still is one of the central objectives pursued by different higher education institutions, including the Application-oriented colleges or universities. Reports show that these schools make a great contribution to social and economic development and they are influenced by the forces driving change in the various sectors, including education, industries, and society. Literature shows that engagement has an essential role for students' achievement. Indeed, there is a consensus that student engagement is one of the key contributors to reinforcing learning and retention. To learners enrolled in these universities, creativity is of paramount importance, as well. More specifically, given that students are seen as the main contributors to societal development, universities have been seeking to foster creativity among individuals by establishing creativity-nurturing programs. As creativity is significant in education these days, the present study attempts to consider the conception of creativity and its role in how it can assist in cultivating student engagement and success in Application-oriented Colleges. Accordingly, some educational implications are offered for educators, learners, and syllabus designers.

Abstract
OBJECTIVES To determine the success, survival, peri-implant health and prosthetic complications in head and neck cancer patients receiving oral rehabilitation utilising dental implants between 2008 and the present day. MATERIALS AND METHODS Service evaluation. Survival Group: Retrospective review of records to determine implant survival and prosthetic complications. Success Group: Examination to determine implant success and health. RESULTS Survival Group: 260 implants in 81 individuals, median follow up 49.2 months. 89.3% implant survival at 96 months, no further failures up to 133 months. 40.9% individuals required repair or remake of prosthesis by 72 months - mostly denture re-lines. Success group: 164 implants in 48 individuals, median follow up 56 months. Peri-implant mucositis detected in 22% of fixtures (37.5% individuals); peri-implantitis in 12.8% (25% individuals); 33.3% fixtures exhibiting periimplantitis at 120 months. Previous smoking significantly associated with development of peri-implantitis (HR 2.372, p=0.032, 95CI:1.232, 93.317). Compromised survival (e.g. peri-implantitis), absolute (not in mouth) or clinical failure estimated to occur in 28.1% fixtures at 101 months, mostly due to peri-implantitis. CONCLUSIONS There is a large burden of ongoing care in this cohort, requiring interventions to improve peri-implant health and maintain complex prostheses. Oral rehabilitation and ongoing maintenance in this cohort is complex and multi-disciplinary.

Abstract
PURPOSE 3D virtual models (3DVMs) are nowadays under scrutiny to improve partial nephrectomy (PN) outcomes. Five different Trifecta definitions have been proposed to optimize the framing of "success" in the PN field. Our aim is to analyze if the use of 3DVMs could impact the success rate of minimally invasive PN (mi-PN), according to the currently available definitions of Trifecta. MATERIALS AND METHODS At our Institution 250 cT1-2N0M0 renal masses patients treated with mi-PN were prospectively enrolled. Inclusion criteria were the availability of contrast-enhanced CT, baseline and postoperative serum creatinine, and eGFR. These patients were then compared with a control group of 710 patients who underwent mi-PN with the same renal function assessments, but without 3DVMs. Multivariable logistic regression (MLR) models were used to predict the trifecta achievement according to the different trifecta definitions. RESULTS Among the definitions, Trifecta rates ranged between 70.8% to 97.4% in the 3DVM group vs. 56.8% to 92.8% in the control group (all p values < 0.05). 3DVMs showed better postoperative outcomes in terms of ΔeGFR, ( - 16.6% vs. - 2.7%, p = 0.03), postoperative complications (15%, vs 22.9%, p = 0.002) and major complications (Clavien Dindo > 3, 2.8% vs 5.6%, p = 0.03). At MLR 3DVMs assistance independently predicted higher rates of successful PN across all the available definitions of Trifecta (OR: 2.7 p < 0.001, OR:2.0 p = 0.0008, OR:2.8 p = 0.02, OR 2.0 p = 0.003). CONCLUSIONS The 3DVMs availability was found to be the constant predictive factor of successful PN, with a twofold higher probability of achieving Trifecta regardless of the different definitions available in Literature.

Abstract
OBJECTIVES The objective is to evaluate the long-term clinical survival and performance of direct and indirect resin composite restorations replacing cusps in vital upper premolars. METHODS Between 2001 and 2007, 176 upper premolars in 157 patients were restored with 92 direct and 84 indirect resin composite restorations as part of an RCT. Inclusion criteria were fracture of the buccal or palatal cusp of vital upper premolars along with a class II cavity or restoration in the same tooth. RESULTS Forty patients having 23 direct and 22 indirect composite restorations respectively, were lost to follow-up (25.6%). The cumulative Kaplan-Meier survival rates were 63.6% (mean observation time: 15.3 years, SE 5.6%) with an AFR of 2.4% for direct restorations and 54.5% (mean observation time: 13.9 years, SE: 6.4%) with an AFR of 3.3% for indirect restorations. The Cox regression analysis revealed a statistically significant influence of the patient's age at placement on the survival of the restoration (HR 1.036, p = 0.024), the variables gender, type of upper premolar, type of restoration, and which cusp involved in the restoration had no statistically significant influence. Direct composite restorations failed predominantly due to tooth fracture, indirect restorations primarily by adhesive failure (p < 0.05). SIGNIFICANCE There was no statistically significant difference in survival rates between direct and indirect composite cusp-replacing restorations. Both direct and indirect resin composite cusp-replacing restorations are suitable options to restore compromised premolars. The longer treatment time and higher costs for the indirect restoration argue in favor of the direct technique.

Abstract
INTRODUCTION The objective of our study was to compare the effectiveness of induction in cephalic presentations to that of breech presentations as well as the characteristics of the latter and the maternal-fetal morbidity and mortality. MATERIAL AND METHODS This was a single-center retrospective study carried out at the Lille University Hospital in the Jeanne de Flandre Maternity Hospital including all patients with a breech fetus for whom an induction was indicated beyond 37 weeks of gestation between January 2014 and December 2020. A matching was performed to include 2 cephalic presentations for one breech presentation. The primary outcome was successful induction defined by two things: passage into the active phase (cervical dilatation > 5 cm) and vaginal delivery. RESULTS 101 inductions of breech presentations were included and matched to 202 cephalic presentations. After adjustment by BISHOP score, there was no significant difference in the caesarean section rate between the two groups (25.7% in cephalic vs 33.7% in breech, OR 0.67 [CI95% 0.38-1.18]) or in the rate of transition to active phase (80.7% in cephalic vs 82.2% in breech, OR 1.26 [CI95% 0.65-2.44]). Post-partum blood loss was not significantly different between the two groups (14.4% in cephalic vs 12.9% in breech, OR 1.22 [CI95% 0.57-2.57]). Moderate neonatal acidosis was more frequent in the breech group (6,4% in cephalic vs 15,8% in breech, OR 3.04 [CI95% 1.38-6.71]). CONCLUSION Induction of breech births beyond 37 weeks of gestation appeared to be as effective as induction of cephalic presentations. There was no difference in the rate of caesarean section and transition to active labor. Maternal morbidity was not increased.

Abstract
PURPOSE Adolescent idiopathic scoliosis (AIS) is the most common type of scoliosis that affects children aged 10-18 years old, manifesting in a three-dimensional spinal deformity. This study aimed to explore outcome measures used in defining AIS treatment success. Particularly, analyzing the extent of qualitative and quantitative (radiographic and quality of life domains) measures to evaluate AIS and whether AIS treatment approaches (surgical, bracing and physiotherapy) influences outcomes used as proxies of treatment success. METHODS EMBASE and MEDLINE databases were used to conduct a systematic scoping review with 654 search queries. 158 papers met the inclusion criteria and were screened for data extraction. Extractable variables included: study characteristics, study participant characteristics, type of study, type of intervention approach and outcome measures. RESULTS All 158 studies measured quantitative outcomes. 61.38% of papers used radiographic outcomes whilst 38.62% of papers used quantitative quality of life outcomes to evaluate treatment success. Irrespective of treatment intervention utilized, the type of quantitative outcome measure recorded were similar in proportion. Moreover, of the radiographic outcome measures, the subcategory Cobb angle was predominantly used across all intervention approaches. For quantitative quality of life measures, questionnaires investigating multiple domains such as SRS were primarily used as proxies of AIS treatment success across all intervention approaches. CONCLUSION This study identified that no articles employed qualitative measures of describing the psychosocial implications of AIS in defining treatment success. Although quantitative measures have merit in clinical diagnoses and management, there is increasing value in using qualitative methods such as thematic analysis in guiding clinicians to develop a biopsychosocial approach for patient care.

Abstract
PURPOSE Bladder infusion, which involves filling the bladder with saline prior to catheter removal, has been associated with reduced time-to-discharge and increased success rates in trials without catheter (TWOCs) in perioperative setting. The objective of this study was to evaluate the applicability of this protocol in patients with acute urinary retention (AUR) related to benign prostatic hyperplasia (BPH). METHODS We conducted a retrospective single-center study comparing bladder infusion with at least 150mL of warm saline vs. standard catheter removal during TWOC in patients with BPH-related AUR between January and December 2021. The primary outcome was time to discharge. Secondary outcomes included: TWOC success, and early recurrence of urinary retention defined as recurrence within three months of successful TWOC. RESULTS A total of 75 men were included: 35 in the bladder infusion protocol and 40 in the standard protocol. Baseline characteristics were well balanced between groups. Overall, 35 patients (46.7%) had a successful TWOC without statistically significant difference between groups (P=0.10). Bladder infusion protocol was associated with a shorter median time to discharge (200 vs. 240min, P=0.003). However, patients in the bladder infusion group were associated with a higher risk of early recurrence of urinary retention (30% vs. 0%, P=0.02). CONCLUSION In patients with BPH-related AUR, the saline bladder infusion method reduced time-to-discharge with similar TWOC success rates. Larger studies are needed to properly analyze the risk of early recurrence of urinary retention before any clinical application. LEVEL OF EVIDENCE III.

Abstract
The distal radial approach (DRA) has been proposed as an alternative approach for coronary angiography (CAG) and percutaneous coronary intervention (PCI); however, the predictors of DRA failure and puncture site complications are unclear. Among 7153 consecutive patients undergoing CAG or PCI between November 2018 and January 2021, 3610 patients undergoing CAG or PCI with DRA were analyzed. The primary endpoint of this study was the procedural success, and the secondary endpoint of this study was puncture site complications during procedure. Puncture site complications during procedure were defined as a composite of major bleeding, minor bleeding, arteriovenous fistula, pseudoaneurysm, and neuropathy. The DRA success rate and the puncture site complication rate were 90.4% and 7.7%, respectively. The predictors of DRA failure were low body weight and dual antiplatelet therapy; those of DRA success were PCI and ultrasonography-guided DRA; those of puncture site complications during procedure were low body weight, peripheral arterial disease, dual antiplatelet therapy, anticoagulant therapy, and PCI; and that of no puncture site complications were previous PCI and ultrasonography-guided DRA. The negative predictors of DRA success with no puncture site complication during procedure were low body weight and dual antiplatelet therapy. The positive predictor of DRA success with no puncture site complication during procedure was ultrasonography-guided DRA. We identified the predictors of DRA failure and puncture site complications during procedure in patients undergoing CAG and PCI with DRA. Ultrasonography-guided DRA was associated with a high DRA success rate and a low puncture site complication rate in patients undergoing CAG or PCI with DRA.

Abstract
PURPOSE To present the results obtained with a novel sleeveless and keyless guided implant surgery system. METHODS Inclusion criteria for this multicenter clinical retrospective study were fully or partially edentulous patients who had been treated with a sleeveless and keyless guided implant surgery system (R2Gate®, Megagen), and who had been rehabilitated with fixed restorations, with a minimum follow-up of 1 year. All surgeries and prosthetic procedures were conducted following the same protocol, and data were obtained from the patients' medical records. The outcomes were the fit and stability of the surgical guide, any intra-operative and immediate post-operative complications, any biologic and prosthetic complications that occurred during the 1-year follow-up period, implant survival, and prosthetic success. RESULTS Sixty patients were selected for the installation of 124 implants, through a guided procedure: 66 sleeveless, keyless surgical guides were manufactured. The incidence of immediate intra-operative (lack of space: 12.1%; lack of implant stability 2.6%) and immediate post-operative (pain and discomfort: 6.6%; mild swelling 3.3%) complications was low. In total, 112/124 implants (90.3%) were successfully placed with a guided procedure, in 52 patients; among them, 82 (73.2%) were placed with a flapless procedure. Thirty fixtures supported single crowns (SCs), 42 fixed partial dentures (FPDs) and 52 full-arch (FA) restorations. Sixty-two fixed prosthetic restorations (30 SCs, 22 FPDs and 10 FAs) were delivered; among these restorations, 15 (24.1%) were subjected to immediate functional loading. All implants (100%) survived. Two implants had peri‑implant mucositis (1.6%), two SCs had abutment screw loosenings (1.6%), two FAs and one FPD had ceramic chipping/fracture (2.4%), for an overall prosthetic success amounting to 88.7%. CONCLUSIONS Within the limits of this study, this novel guided surgery system appeared to be clinically reliable; further studies are needed to confirm these results. STATEMENT OF CLINICAL RELEVANCE The use of sleveless and keyless surgical guides can be clinically reliable and may be represent a valid option for the surgeon.

Abstract
In this paper, I will propose a formulation of the contingentism/inevitabilism (C/I) debate that does not require of alternatives to present-day scientific theories that they are equally successful, but rather asks whether they are historically possible. I argue that the debate has already, over the past decades, moved towards a more historical interpretation of the issue, and that it is worth exploring what it would entail to let go of normative considerations altogether. Different answers to inevitability questions still retain the philosophical relevance that originally led Ian Hacking to explore philosophical disagreement in terms of the contingentism/inevitabilism debate.1.

Abstract
BACKGROUND Tooth-colored onlays and partial crowns for posterior teeth have been used increasingly in clinics. However, whether onlays/partial crowns could perform as well as full crowns in the posterior region was still not evaluated thoroughly. METHODS A literature search was conducted without language restrictions in Pubmed, Embase, Cochrane Central Register of Controlled Trial and Web of science until September 2021. RCTs, prospective and retrospective observational studies with a mean follow-up of 1 year were selected. Cochrane Collaboration's tool was adopted for quality assessment of the RCT. The quality of observational studies was evaluated following Newcastle-Ottawa scale. The random-effects and fixed-effects model were employed for meta-analysis. RESULTS Four thousand two hundred fifty-seven articles were initially searched. Finally, one RCT was identified for quality assessment and five observational studies for qualitative synthesis and meta-analysis. The RCT was of unclear risk of bias while five observational studies were evaluated as low risk. The meta-analysis indicated no statistically significant difference in the survival between onlays/partial crowns and full crowns after 1 year (OR = 0.55, 95% CI: 0.02-18.08; I2 = 57.0%; P = 0.127) and 3 years (OR = 0.65, 95% CI: 0.20-2.17; I2 = 0.0%; P = 0.747). For the success, onlays/partial crowns performed as well as crowns (OR = 0.58, 95% CI: 0.20-1.72; I2 = 0.0%; P = 0.881) at 3 years. No significant difference of crown fracture existed between the two methods (RD = 0.00, 95% CI: - 0.03-0.03; I2 = 0.0%; P = 0.972). CONCLUSIONS Tooth-colored onlays/partial crowns performed as excellently as full crowns in posterior region in a short-term period. The conclusions should be further consolidated by RCTs with long-term follow-up.

Abstract
BACKGROUND The high unmet neurosurgical burden in low- and middle-income countries has necessitated multiple global neurosurgical collaborations. We identified these collaborations and their peer-reviewed journal publications and evaluated them using a modified version of the Framework for Assessment of InteRNational Surgical Success (FAIRNeSS). METHODS A systematic literature review yielded 265 articles describing neurosurgery-focused collaborations. A subset of 101 papers from 17 collaborations were evaluated with the modified FAIRNeSS criteria. Analysis of trends was performed for both individual articles and collaborations. RESULTS Most of the articles were general reviews (64), and most focused on clinical research (115). The leading collaboration focus was workforce and infrastructure development (45%). Composite FAIRNeSS scores ranged from 7/34 to 30/34. Average FAIRNeSS scores for individual articles ranged from 0.25 to 26.75, while collaboration-wide FAIRNeSS score averages ranged from 5.25 to 20.04. There was significant variability within each subset of FAIRNeSS indicators (P value <0.001). Short-term goals had higher scores than medium- and long-term goals (P value <0.001). Collaboration composite scores correlated with the number of papers published (R2 = 0.400, P = 0.007) but not with the number of years active (R2 = 0.072, P = 0.3). Finally, the overall agreement between reviewers was 53.5%, and the overall correlation was 38.5%. CONCLUSIONS Global neurosurgery has no established metrics for evaluating collaborations; therefore, we adapted the FAIRNeSS criteria to do so. The criteria may not be well suited for measuring the success and sustainability of global neurosurgery collaborations, creating a need to develop a more applicable alternate set of metrics.

Abstract
Objectives The first permanent molar (FPM) is considered the tooth most susceptible to caries, as it is the first permanent tooth to erupt in the oral cavity, making it susceptible to environmental conditions that may appear as caries, hypoplasia, or hypomineralization. Several treatment options are available for managing deep caries, including root canal treatment (RCT). However, there is a lack of data on the success and failure rates of RCT in FPM among children. This study aimed to determine the success and failure rates of RCT in FPM among children and related factors. Methods This retrospective cohort study was conducted at three major centers in Jeddah, Saudi Arabia. Children aged 9–18 years who underwent an RCT between 2010 and 2019 were included. Clinical and radiographic examinations were also performed. Results Based on the loose criteria, most of the evaluated teeth (79.6%) were successfully treated. The treatment failed in only 20.4% of participants. Older patients and teeth with acceptable restoration quality had an increased success rate compared to younger patients and teeth with unacceptable restoration quality. A shorter time lapse between treatment and assessment resulted in a lower success rate compared to a longer time lapse. Based on strict criteria, 72.9% of the patients were successfully treated. The use of a microscope and teeth with acceptable restoration quality resulted in an increased success rate compared to teeth treated without the microscope and with unacceptable restoration quality. Conclusions The success rate of this procedure was high. Several factors, including older age, acceptable restoration quality, and the use of a microscope, increase the probability of success.

Abstract
Background To clarify does physical performance affect success in highest-level soccer, the purpose of the present study was to identify differences in technical-tactical performance (TP) between teams covering high and low running performance (RP) during the UEFA Champions League (UCL) matches. Methods The RP and TP data were collected from UCL group stage matches in the 2020/21 season. RP variables included total distance covered (TD), high intensity running (HIR), total distance when in ball possession (TDB), and high intensity running when in ball possession (HIRB). TP variables included goal chances, shots, shots on target, passes, accurate passes, key passes, key passes accurate, crosses, crosses accurate, counter attacks, counter attacks with a shot, high pressing, high pressing successful, low pressing, low pressing successful, tackles, tackles successful, entrances to the opponent’s box, total actions, and successful actions. K-means cluster analysis method was used to classify teams covering (i) low and high TD, (ii) low and high HIR, (iii) low and high TDB, (iv) low and high and HIRB. Linear mixed models were used to identify differences in teams’ TP according to their RP. Pearson’s correlations were used to establish direct association between team TP and RP. Results Similar TP were observed whether teams covering high or low TD/HIR. Teams covering greater TDB/HIRB had more goal chances, shots, shots on target, passes, accurate passes, key passes, accurate key passes, crosses, successful high pressing, entrances to the opponent’s box, total actions, and successful actions were observed (all moderate to very large effect sizes. Significant association between specific TP variables and TDB/HIRB were evidenced (Pearson’s r = 0.35–0.96, all p < 0.05). Conclusion Covering greater TDB and HIRB may allow more frequent execution of fundamental TP which are considered essential for match success, indicating that RP when team has ball in possession is important determinant of success in highest-level soccer. This study shows that physical performance affect success in highest-level soccer.

Abstract
Background: A review on the health information systems (HISs) of each country should not be limited only to data collected and reported normally by the service providers. In this regard, the first step for the development in any national project is exploring the experiences of other countries worldwide, especially those with economic, political, cultural, and regional partnerships, and then using their resources and documents to have a broader attitude and a better profitability in planning the development strategy. This study was conducted to review the studies conducted on the causes of HIS success and failure, and the challenges faced by developing countries in using these systems. Methods: The present study was a narrative review to meet the aim of the study, and those studies published in English language in PubMed, Web of science, and Science Direct databases and Scopus between 2000 and 2020 were investigated. Primary keywords used to extract content in these databases were as follows: "health information system", "challenges", "success", "failure", "developing country", and "low and middle income country". Results: After searching the above-mentioned databases, 455 studies were retrieved. Finally, 24 articles were used. The causes of success and failure of HISs were finally divided into 4 categories: human, organizational, financial and technical factors. A total of 30 subfactors were extracted for different factors. Moreover, the findings indicated that many of the challenges that developing countries face in using HISs are influenced by the social, cultural, economic, geographical, and political conditions of these countries. The results represented that organizational and human elements play a critical role in the advancement or falling of the health HIS in growing countries. Conclusion: There is a demand to come up with flexible standards for designing and deploying HISs to address these complexities. Several solutions can be found to address the obstacles and problems facing HISs in developing countries, including formulating strategic plans and policies necessary for the development of national HISs.

Abstract
PURPOSE Strabismus, whether congenital or acquired, is a common visual and cosmetic problem, especially for the young. Adjustable suture strabismus surgery is not in vogue in our country. This technique gives the surgeon a second attempt to provide a better outcome for the patients. Our objective was to assess the long-term success of adjustable strabismus surgery in terms of postoperative alignment. METHODS We carried out a prospective study utilizing the fornix approach for adjustable strabismus surgery, in mainly horizontal, but also vertical strabismus in adults and cooperative children, to enhance the postoperative outcomes. The patient characteristics, preoperative deviation, type and pattern of strabismus, were evaluated and analyzed. The postoperative alignment was evaluated at 1 year and beyond, to assess the success of this adjustable surgery. RESULTS This study recruited 50 adults and children with a female predominance of 39 (78%); and with the mean age being 18.34 ± 9.88 years. Exotropia was the primary diagnosis in the majority with 21 (42%) cases; with purely horizontal strabismus in 23 (46%) cases. The mean preoperative horizontal deviation was 48.76 ± 20.35 prism diopters (PD) and the mean postoperative horizontal deviation was 2.73 ± 3.63 PD. The mean preoperative vertical deviation was 4.8 ± 8.54 PD whereas the mean postoperative vertical deviation was 0.86 ± 1.73 PD. The Wilcoxon Signed Ranks test analyzed the difference between the two which was statistically significant (p = 0.000). Surgical success, defined as postoperative horizontal alignment within ≤ 10 PD of orthotropia at the end of one year or more of follow-up after surgery, was achieved in 49 (98%) cases. The average follow-up was 21.47 ± 8.7 months. CONCLUSION Adjustable strabismus surgery has very good long-term outcomes in terms of postoperative alignment and patient satisfaction.

Abstract
Laryngotracheal reconstruction is the most common and effective treatment in childhood subglottic stenosis (SGS). Our aim is to review the success rate of laryngotracheoplasty (LTP) in pediatric high grade SGS cases in our tertiary center. The retrospective review was conducted on children with high grade subglottic stenosis who had undergone laryngotracheoplasty over a 7-year period (2013-2020) in tertiary pediatric care. A total of 20 patients who had history of high grade SGS during the stipulated period were included. All of them had undergone LTP. Decannulation was considered the primary outcome measure of success. Surveillance bronchoscopy was performed one year post airway reconstruction to detect residual stenosis. From January 2013 to December 2020, 20 patients aged between 1 and 16 years old underwent LTP. Among them, 10 patients (50%) had Grade III SGS while 5 had Grade III SGS with glottis stenosis (25%). The remaining 5 (25%) had severe Grade IV stenosis. Decannulation was achieved in 14 patients overall (70%) including 1 with revision. These 14 patients who achieved decannulation included 7 out of the 10 patients (70%) with Grade III, 2 out of the 5 (40%) patients with Grade III with glottic involvement, and 4 out of the 5 patients (80%) with Grade IV SGS. Fifteen (80%) patients had double stage LTP while 5 patients had single stage LTP. The study suggests that LTP is a promising approach in the treatment of Complex SGS. Furthermore, pediatric SGS, which is inherently complicated, can be treated with LTP effectively.

Abstract
Environmental stewardship is increasingly important as human actions threaten the natural world. Now, more than ever, it is necessary to understand what makes stewardship initiatives successful. This study investigates stewardship success in the Niagara Region of Ontario, Canada. Specifically, the research seeks to determine what factors are associated with the success of environmental stewardship initiatives, differences between stewardship organizations (staff-based vs. volunteer-based), and reasons why those factors are important. Ten factors for successful stewardship initiatives were uncovered. Differences between volunteer and staff-based organizations were revealed, especially regarding factors of motivations and capacity. Qualitative analysis provided rich insights into why factors were important for success, with the physical ability to conduct the work and the importance of motivation being highlighted. The findings from the study provide a basis for future research which expands the empirical contexts for understanding stewardship success, broadens the variety of stewardship organizations considered, and incorporates additional measures of success.

Abstract
INTRODUCTION The Maternal and Child Health (MCH) Pipeline Training Program, promotes development of a diverse health workforce by training undergraduate students from underrepresented minorities. We aimed to evaluate the success of this program based on three domains: (1) demographic characteristics, (2) academic and career development, and (3) attitudes towards the field of MCH and the training programs among graduates. METHODS Three domains of success were determined through a collaborative effort between current program directors and the funding agency project officers. The survey with questions related to the three domains was distributed via an online platform to graduates from seven sites (one former site and six current sites). Data were analyzed and presented utilizing descriptive statistics. RESULTS The survey was distributed to 550 graduates, 162 responded (37% response rate). Demographically, 78% were female, 54% were Black/African American, 22% were Latinx and 83% did not report any disability. Eighty percent of respondents applied to graduate/professional schools, 67% received admission. Graduates often continued to work in MCH fields (70%). Majority felt confident and knowledgeable in the field (89%) and agreed the faculty were supportive at their training sites (90%). CONCLUSION The study highlights successes in recruiting from underrepresented minorities, particularly Black/African Americans and first-time college goers in the family into the MCH Pipeline Training Programs. Programs were successful in furthering academic and career development for most trainees. Attitudes towards MCH and the training programs were overwhelmingly positive. Continued support of these programs is critical in addressing health disparities and achieving health equity.

Abstract
Surgeon-scientists are uniquely positioned to contribute to our understanding of the fundamental biology of surgical disease and to bring a unique perspective that leads to innovation in the diagnosis and treatment of many conditions. However, it is broadly recognized that due to the changing landscape of surgery and science, the surgeon-scientists of today face multiple challenges in this pursuit. Today, surgeon-scientists face an increased pressure from their department and hospital to generate clinical revenue, decreased availability of grant funding, greater administrative burden, rising complexity of fundamental research, increased medical school debt, and a growing desire for work-life balance. Given that survival of surgeon-scientists is critical for the progress of not only surgery but medical innovation at large, many surgical societies, notably the Association for Academic Surgery (AAS) and the Society of University Surgeons (SUS) have focused on the issues faced by surgeon-scientists. In this regard, the Basic and Translational Research Committee of the AAS and the Research Committee of the SUS organized a hot topic session at the 2021 Academic Surgical Congress in which experts discussed and addressed many issues concerning the surgeon-scientist pathway. This manuscript provides an overview of the issues discussed at this session.

Abstract
PURPOSE Treatment success can be defined by asking a patient how they perceive their condition compared to prior to treatment, but it can also be defined by establishing success criteria in advance. We evaluated treatment outcome expectations in patients undergoing surgery or non-operative treatment for cervical radiculopathy. METHODS The first 100 consecutive patients from an ongoing randomized controlled trial (NCT03674619) comparing the effectiveness of surgical and nonsurgical treatment for cervical radiculopathy were included. Patient-reported outcome measures and expected outcome and improvement were obtained before treatment. We compared these with previously published cut-off values for success. Arm pain, neck pain and headache were measured by a numeric rating scale. Neck disability index (NDI) was used to record pain-related disability. We applied Wilcoxon signed-rank test to compare the expected outcome scores for the two treatments. RESULTS Patients reported mean NDI of 42.2 (95% CI 39.6-44.7) at baseline. The expected mean NDI one year after the treatment was 4 (95% CI 3.0-5.1). The expected mean reduction in NDI was 38.3 (95% CI 35.8-40.8). Calculated as a percentage change score, the patients expected a mean reduction of 91.2% (95% CI 89.2-93.2). Patient expectations were higher regarding surgical treatment for arm pain, neck pain and working ability, P < 0.001, but not for headache. CONCLUSIONS The expected improvement after treatment of cervical radiculopathy was much higher than the previously reported cut-off values for success. Patients with cervical radiculopathy had higher expectations to surgical treatment.

Abstract
BACKGROUND A lumbar puncture (LP) is performed in the emergency room for diagnostic purposes; unsuccessful or traumatic LPs can complicate decision making. The sitting position has a larger interspinous process compared to lateral recumbent and is safer in sick neonates at risk for cardiac and respiratory instability. PURPOSE Our study aims to determine which position (lateral recumbent or sitting) is associated with a greater likelihood of successful lumbar puncture in infants <3 months when performed in the emergency room. BASIC PROCEDURES This is a retrospective chart review in infants aged <3 months who had a LP performed in a pediatric emergency room. The primary outcome was the rate of successful LPs, defined as obtaining adequate CSF to send for all studies. The secondary outcome was the proportion of atraumatic LPs by position, defined as <500 RBCs or < 10,000 RBCs. MAIN FINDINGS A total of 557 charts were reviewed with 116 in the sitting position and 441 in the lateral recumbent position. The primary outcome of adequate CSF fluid collection was not significantly different between groups (63% sitting position versus 58% lateral recumbent position; p = 0.22). In addition, the proportion of atraumatic LPs showed no significant difference regardless of RBC cutoff (<500 RBCs p = 0.83, <10,000 RBCs p = 0.60). PRINCIPLE CONCLUSIONS This study found no evidence that there is a difference in rate of LP success nor the proportion of traumatic LP in infants less than 3 months of age when positioned in the sitting position compared to the lateral recumbent position.

Abstract
INTRODUCTION The primary aim was to determine the key variables in a new practitioner's success from the perspective of pharmacy employers. A secondary aim was to describe the use of a modified Delphi process to collect quality information from external constituents. METHODS A historical review of the literature was conducted to ensure the inquiry extended existing thinking and to aid the development of questions. An asynchronous, online two-round modified Delphi process was used to gather input and develop consensus. The findings were verified by crosswalking with the Habits of Mind. Additionally, the strategies for inviting panelists, practitioner response rates, and the amount and quality of the data collected were examined. RESULTS The historical review yielded 25 articles that were categorized by disciplines studied, methods used, and characteristics found. Fourteen seasoned employers participated. Nine themes describing the behaviors and practices of exceptional new practitioners were identified. These themes were categorized into three groups: Change-Leader, Self-Manager, or Relationship-Builder. Additionally, all the themes mapped to multiple Habits of Mind. As a method for constituent input, the Delphi process yielded employer response rates per school ranging from 10% to 67% and produced five single-spaced pages of text (2124 words) for analysis. CONCLUSIONS These descriptions of behaviors and practices of exceptional new practitioners build upon existing literature and provide additional guidance for professional development curricula. Additionally, an asynchronous, online Delphi panel can be a useful method to glean important insights from experienced pharmacy employers.

Abstract
COVID-19 has caused over 260 million confirmed cases and over 5 million deaths globally. The results of statistical and multiple criteria analyses on the success of 169 countries and on COVID-19 cumulative cases and excess deaths show that the prosperity of a country relates directly to the consequences due to the pandemic. The topic of this article is the Country Success and COVID-19 (CSC) Map of the World. As a country's success grows, this map shows how cumulative cases of COVID-19 increase; at the same time, excess deaths decrease. The indicators in the system of criteria regarding country success and sustainability are interrelated. Conditional country successes remain quite similar, despite changes to the numbers of countries and their indicators. Likewise, the seven clusters of countries under consideration group together independently of which system of indicators had been applied for their analysis. The 2020 Inglehart-Welzel Cultural Map of the World, which is grounded on surveys, and the CSC Map, which is grounded on statistical indicators, have axes that correlate with one another significantly. The CSC Map Model explains over 63% of the dispersions pertinent to COVID-19 cumulative cases, over 52% of COVID-19 excess deaths, and over 95% of country success variables. The layout of the clusters on the CSC Map changes little over time. Upon performance of the correlation analysis, it was established that strong and statistically significant relationships exist between 169 countries success and sustainability linked with their current air quality score (r = 0.602, p < 0.01) and the environmental performance index (EPI) score (r = 0.931, p < 0.01). The results obtained show that when a country's EPI score and current air quality improve by 1%, excess deaths decrease, respectively, by 2.33 and 1.55%. Global integrated analysis on country successes, COVID-19 cumulative cases, and excess deaths comprise this study.

Abstract
Introduction The Maternal and Child Health (MCH) Pipeline Training Program, promotes development of a diverse health workforce by training undergraduate students from underrepresented minorities. We aimed to evaluate the success of this program based on three domains: (1) demographic characteristics, (2) academic and career development, and (3) attitudes towards the field of MCH and the training programs among graduates. Methods Three domains of success were determined through a collaborative effort between current program directors and the funding agency project officers. The survey with questions related to the three domains was distributed via an online platform to graduates from seven sites (one former site and six current sites). Data were analyzed and presented utilizing descriptive statistics. Results The survey was distributed to 550 graduates, 162 responded (37% response rate). Demographically, 78% were female, 54% were Black/African American, 22% were Latinx and 83% did not report any disability. Eighty percent of respondents applied to graduate/professional schools, 67% received admission. Graduates often continued to work in MCH fields (70%). Majority felt confident and knowledgeable in the field (89%) and agreed the faculty were supportive at their training sites (90%). Conclusion The study highlights successes in recruiting from underrepresented minorities, particularly Black/African Americans and first-time college goers in the family into the MCH Pipeline Training Programs. Programs were successful in furthering academic and career development for most trainees. Attitudes towards MCH and the training programs were overwhelmingly positive. Continued support of these programs is critical in addressing health disparities and achieving health equity.

Abstract
Recent literature has addressed initial coin offering (ICO) projects, which are an innovative form of venture financing through cryptocurrencies using blockchain technology. Many features of ICOs remain unexplored, leaving much room for additional research, including the success factors of ICO projects. We investigate the success of ICO projects, with our main purpose being to identify factors that influence a project's outcome. Following a literature review, from which several potential variables were collected, we used a database comprising 428 ICO projects in the banking/financial sector to regress several econometric models. We confirmed the impacts of several variables and obtained particularly valuable results concerning project and campaign variables. We confirmed the importance of a well-structured and informative whitepaper. The proximity to certain markets with high availability of financial and human capital is also an important determinant of the success of an ICO. We also confirm the strong dependency on cryptocurrency and the impact of cryptocurrency valuations on the success of a project. Furthermore, we confirm the importance of social media in ICO projects, as well as the importance of human capital characteristics. Our research contributes to the ICO literature by capturing most of the success factors previously identified and testing their impacts based on a large database. The current research contributes to the building of systems theory and signaling theory by adapting their frameworks to the ICO environment. Our results are also important for regulators, as ICOs are mainly unregulated and have vast future potential, and for investors, who can benefit from our analysis and use it in their due diligence.

Abstract
Introduction Bone-borne miniscrew assisted palatal expansion (MAPE) is a common technique to improve maxillary transverse deficiency in young adolescents. Adult patients usually present a challenge, as they often require additional surgical assisted maxillary expansion (SARPE). There is still no clear statement about non-surgical expansion in adult patients using this technique. The aim of this study was to evaluate the success and complication rate of non-surgical palatal expansion in adults utilizing MAPE with a novel force-controlled polycyclic expansion protocol (FCPC). Methods This consecutive study consisted of 33 adult patients with an average age of 29.1 ± 10.2 years (min. 18 years, max. 58 years), including one dropout patient. First, four miniscrews were inserted and after 12-weeks latency, the expander was placed and the FCPC protocol was applied (MAPE group). In case of missing expansion, a SARPE was performed (SARPE group). After maximum expansion, a cone beam CT was made and widening of the midpalatal suture was measured. The outcome variables were successful non-surgical expansion and, with sample size power above 80%, the odds of failed non-surgical expansion and associated complications were evaluated. The primary predictor variable was age. Statistical analysis was performed using R (Version 3.1) to calculate power, to construct various models for measuring the odds of requiring surgical intervention/complications, and others. Results Successful non-surgical expansion was achieved in 27 patients (84.4%), ranging from 18 to 49 years. Mean age differed significantly between both groups (26.8 ± 8.2 years vs. 41.3 ± 9.9 years; p < 0.001). Mean expansion at the anterior and posterior palate for the MAPE group was 5.4 ± 1.5 mm and 2.5 ± 1.1 mm, respectively. Among these subjects’ complications were observed in 18.5%. Age significantly increased the odds of complications (p = 0.019). Conclusions 1. The success rate of MAPE among individuals aged 18 to 49 years was 84.4%. 2. A V-shaped expansion pattern in the antero-posterior dimension was mostly observed. 3. Complications were significantly associated with age. 4. A careful expansion protocol seems to be beneficial to prevent unfavorable results in adult patients. Trial registration Consecutive cohort study, Review Board No. EK-2-2014/0016.

Abstract
OBJECTIVE We evaluated the effect of the learning curve on percutaneous thrombectomy (PT) outcomes for the treatment of lower extremity deep vein thrombosis (DVT). METHODS The present study was conducted between October 2019 and September 2020 and included 80 patients who had undergone PT to treat lower extremity DVT of the common iliac, external iliac, common femoral, femoral, and popliteal veins. For thrombectomy, aspiration and mechanical thrombectomy procedures were performed until the thrombus had completely dissolved using the Dovi aspiration system and Mantis mechanical thrombectomy system (Invamed, Ankara, Turkey). A total of 80 patients were divided equally into four groups, with the first 20 cases in group 1, the second 20 cases in group 2, the third 20 cases in group 3, and the final 20 cases in group 4. The groups were compared for the demographic characteristics, intraoperative outcomes, complication rates, and procedure success. RESULTS All demographic parameters were similar between the four groups. The mean operative time was 139.3 minutes for group 1, 134.8 minutes for group 2, 111.3 minutes for group 3, and 106.7 minutes for group 4. Statistical analysis revealed that the operative time was significantly shorter for groups 3 and 4 compared with that for groups 1 and 2. In addition, the fluoroscopy time was significantly decreased in groups 3 and 4 (P = .001). The complication rate was similar between the four groups (P = .899). However, success was significantly increased after the first 20 cases, and the remaining three groups had a significantly higher success rate compared with group 1 (70% for group 1, 90% for group 2, 95% for group 3, and 100% for group 4; P = .024). CONCLUSIONS Success in the performance of PT for the treatment of acute lower extremity DVT reaches satisfactory levels after 20 cases. Additionally, operation time and fluoroscopy time are significantly decreased after 40 cases and then start plateau.

Abstract
Background It is known that the success rates of phase III trials for solid cancers are low. The aim of this study was to investigate factors related to trial design and operation that were associated with the probability of the success of phase III trials for solid cancers based on the latest comprehensive data. Methods Relevant clinical trials, started between September 2007 and December 2017, were retrieved from ClinicalTrials.gov. Then, variables related to the selected trials such as types of primary endpoint and duration of trial enrollment were collected from the literature and ClinicalTrials.gov. Based on the collected data, a multivariate logistic regression analysis was conducted to find factors associated with the successful results. Results Four hundred phase III trials were found eligible for the study. Unsuccessful trials were 207 and successful trials were 193. As a result of multivariate logistic regression analysis, factors that presented a statistically significant relationship were primary endpoint (Odds ratio [OR]: 2.79 [95% CI: 1.59–4.89]), control arm (OR: 3.06 [95% CI: 1.39–6.73]), start year of trial (OR: 3.28 [95% CI: 1.87–5.77]), and duration of trial enrollment (OR: 0.77 [95% CI: 0.60–0.99]). Conclusion Type of primary endpoints (time-to-event endpoints other than overall survival), control arm (treatments with lower evidence level, placebo or best supportive care), and duration of trial enrollment (faster enrollment speed) were associated with phase III trial success.
