Abstract
The aim of standardizing care is to enhance patient outcomes and optimize healthcare delivery by minimizing variations in care and ensuring the efficient allocation of healthcare resources. Despite these potential benefits to patients, healthcare providers and the healthcare system, standardization may also disadvantage these groups. With a specific focus on congenital diaphragmatic hernia, this article will review the promise and pitfalls of standardization, as well as a potential path forward that uses standardization to improve outcomes in this rare and complex disease process.

Abstract
Research in surgery faces intrinsic difficulties such as the lack of reproducibility of surgical operations, self-referring surgeons, decentralized data. Establishing a community of qualified researchers across surgeons is crucial. Clinical networks have been proposed as solutions to many challenges in surgical research, yet their implementation remains uncommon, especially for surgical trialists. The extent of literature produced by networks remains unclear, but fostering such collaborations could enhance the overall quality of surgical research. We conducted review focusing on research networks in colorectal surgery to assess their workload and impact in the literature and identify factors contributing to their durability. Following PRISMA guidelines, we searched for articles published through research networks. Networks were categorized by subspecialty, and specific items were retrieved for further classification. A survey was administered to twenty experts in colorectal surgery or research networking. A total of 2490 manuscripts were screened, and 397 networks identified. Of these, 96 were colorectal networks contributing to 492 publications, with 28 networks having five or more publications. Seventeen networks were affiliated with International or National societies, and only 5 conducted both prospective trials and RCTs. Twenty networks reported national or population-based data, and 26 networks lasted for more than 5 years. Sixteen experts participated in the survey, with an 80 % compliance rate, and 12 of them have been involved in creating a surgical network. The large majority of experts advocate the establishment of guidelines for networks creation in the surgical community.

Abstract
Background Congenital Diaphragmatic Hernia is a malformation of the diaphragm resulting in ongoing clinical symptoms and problems. Mortality remains high, particularly where there are other issues involved. Tracking a patient throughout their lifetime to understand the full impact on health and function is challenging. CDH UK is a registered charity supporting anyone affected by CDH. It has over 25 years of experience and a broad range of patient experience and knowledge. Aims To develop a patient journey with timepoints of significance. Methods We studied our own data and looked at what we already knew from publications and medical advisors. We recruited a focus group, plotted out stages and timepoints through their "lived" experiences using the Team Idea Mapping method. We then compared these experiences to our own data, to identify the common issues in daily life and care. Outcome We have developed a patient journey through the eyes of the patient and turned it into a patient friendly infographic. This can be used as a tool to help understand the CDH Journey throughout a patient's lifetime. CDH UK has already used this to create a first prototype of a mobile application. It has also further helped to recognize areas of patient concern and to improve services and resources. Discussion This can be used as a basis for care and research, including standards, benchmarking, transition and helping improvements in healthcare, education, family life and social settings. Potentially holding clues as to the etiology and pathology of the condition and an opportunity to further explore theories and unanswered questions. It may help improve counselling and bereavement care, resulting in better general and mental health outcomes.

Abstract
Ventricular dysfunction may be found in 40% of newborns with CDH, and is not only a predictor of disease severity, but also mortality and need for ECMO. We conducted this study to assess the utility of serial echocardiography in management of newborns with CDH and their survival outcomes. This is a retrospective study, wherein the demographic, clinical and echocardiographic data from our local CDH registry and hospital clinical database were analyzed to study the correlation of timed echocardiographic findings with mortality and other outcomes. Fourty-two newborns with CDH were admitted during the study period (M/F:19/23), with median gestation of 38 weeks (IQR:36-39) and birth weight of 2.83 kg (IQR 2.45-3.17). Thirty-one were left-sided, seven right, one central, and three bilateral hernias. Twelve infants (28%) died in early infancy. Three infants were excluded from analysis due to either palliation at birth or significant cardiac anomaly. A total of 137 echos from 39 infants were analyzed. Seventy percent of newborns who died and had an echo within the first 72 h, were noted to have suffered from moderate to severe PH. Birth weight < 2.8 kg, RVSP > 45.5 in the first 72 h and postoperative VIS > 23.5 and RSS > 4.3 were good predictors of mortality. Markers of elevated pulmonary pressures and cardiac function were useful in guiding therapy. Serial timed functional echocardiography (f-Echo) monitoring allows targeted therapy of patients with CDH. Birth weight, initial severity of pulmonary hypertension and postoperative RSS and VIS may be useful in predicting mortality.

Abstract
Abstract
Congenital diaphragmatic hernia (CDH) is a rare developmental anomaly in which abdominal contents herniate into the thoracic cavity due to underdevelopment of the diaphragm, possibly leading to pulmonary hypoplasia. Whereas surgery is not the first priority in treatment, it must be performed within a window of 2 weeks and after hemodynamic stability has been achieved. The patient described in this case report had a CDH of the jejunum, ileum, colon and left kidney diagnosed in a boy of South Asian origin who presented with tachypnea in the third hour of life. Imaging studies conducted included chest X-ray, chest ultrasound including echocardiogram, and abdominal and pelvic ultrasound. Treatment and management were successful despite complications. Future research on CDH is warranted in the populations in the Middle East, and local guidelines must be generated in order to improve diagnosis, treatment and prognosis.

Abstract
UNLABELLED To assess the global research landscape in the field of Posterior urethral valve (PUV), a scientometric study was conducted to determine the quantity and quality of the research output and get insight into the key research areas and pattern of collaboration in the research community. METHODS Primary data was acquired from the Scopus® database. Various parameters like the total research productivity, citations, citations per publication, citations per year, citations per publication per year, the scientific output of countries, institutions, authors, and journals were calculated. Key research areas were inferred by examining the top-cited articles (citations >150). Collaborative maps were generated by calculating co-authorship links amongst countries and authors using VOSviewer software. RESULTS One thousand seven hundred fourteen results were found published from 1913 to 2019, receiving a total of 27,253 citations, authored by 5138 authors from 125 countries. The top three countries were the United States of America (USA), India, and the United Kingdom (UK). The leading institutes were the Children's Hospital Boston, USA (n = 48), All India Institute of Medical Sciences (AIIMS, Delhi), India (n = 38), and Great Ormond Street Hospital, UK (n- = 27). The journals which published the most articles on PUV were the Journal of Urology (n = 278), Journal of Pediatric Urology (n = 121), followed by Urology (n = 86). Leading authors were Glassberg, K. L and Bajpai M (n = 17, each), Canning DA & Kajbafzadeh, AM (n = 16, each), followed by Peters CA with 14 manuscripts. The top-cited documents (n = 10) received 2104 citations and were published between 1986 and 2010. The key areas of interest found were "long-term outcomes" (n = 4) and "fetal surgery" (n = 2). The most productive countries were also the most collaborative countries (the USA and UK). CONCLUSION In the research landscape of PUV, the USA, Children's Hospital Boston, and Glassberg, K. L, along with Bajpai, M were the top contributors in terms of the country, organization, and authors, respectively. The "Journal of Urology" and "Pediatric Nephrology" stands out in terms of bibliometric parameters considered. The hotspot topics based on the number of citations received were "long-term outcomes" and "fetal surgery" in PUV. The most productive countries were also the most collaborative countries (the USA and UK).

Abstract
Purpose: Anorectal malformations (ARM) are one of the most challenging congenital malformations in pediatric surgery. We aimed to assess the research activity on ARM over the last five decades. Methods: Data on original research publications were retrieved from the Web of Science Core Collection (1970–2020), and analyzed for countries, authors, scientific journals, and top-ten papers. Scientific quantity was assessed by the number of publications. Research quality was estimated from the number of citations, average citation rate per item (ACI), and h-index. Results: A total number of 1595 articles with 19,419 citations (ACI = 12.2; h-index = 54) were identified. The annual number of publications and citations significantly increased over time (p < 0.0001). The USA (n = 386; 24.2%), Japan (n = 153; 9.6%), and China (n = 137; 8.6%) were the most productive countries; and the USA (n = 7850; ACI = 20.3; h-index = 44), Japan (n = 1937; ACI = 12.6; h-index = 21), and the Netherlands (n = 1318; ACI = 17.3; h-index = 22) were the top cited countries. Articles were preferentially published in JPS (n = 391; 24.5%), PSI (n = 181; 11.3%), and EJPS (n = 56; 3.5%). Top-ten cited papers focused on classification (n = 1), surgical technique (n = 3), associated syndromes (n = 2), postoperative outcome (n = 3), and basic research (n = 1). Conclusion: This bibliometric study provides valuable insights into the global development of ARM research, and shows that clinical studies and international collaborations dominate in this field.

Abstract
Congenital diaphragmatic hernia (CDH) is a congenital anomaly characterized by a defect in the diaphragm. Despite the recent improvements in its treatment, CDH is associated with a high rate of neonatal mortality, which is often related to pulmonary hypoplasia (PH) as well as pulmonary hypertension. A better understanding of the underlying pathological mechanisms of PH in CDH could help establish a new treatment to improve its prognosis. In this study, we investigated serum biological profiles in neonates with CDH. For comprehensive investigation, umbilical cord serum samples were collected from isolated CDH cases (n = 4) and matched healthy controls (n = 4). Samples were analyzed using liquid chromatography–tandem mass spectrometry. A total of 697 proteins were detected; of them, 98 were identified as differentially expressed proteins. Among these differentially expressed proteins, complement C1q subcomponent showed the largest fold change, followed by complement C5. In the pathway enrichment analysis, the complement and coagulation cascades expressed the most significant enrichment (p = 2.4 × 10−26). Thus, the complement pathway might play some role in the pathophysiology of CDH.

Abstract
INTRODUCTION Research on esophageal atresia (EA) has been heavily published over the past decades. Herein, we aimed to study the quantity and quality as well as key topics in EA research with regards to global collaborations among countries and authors. MATERIALS AND METHODS Publications on EA from 1945 to 2018 were extracted from the Web of Science core collection database. Productivity (quantity) was assessed by the number of publications. Quality was estimated from the number of citations, citation rate per item and year, h-index, and impact index. Collaborative networks were evaluated using VOSviewer. All measures were analyzed for countries, authors, and journals. The 10 most cited original articles between 1969 and 2018 in 5-year intervals (n = 100) were manually screened to assess the key points of EA research. RESULTS A total of 2,170 publications from 85 countries published in 388 journals were identified yielding 26,755 citations, both significantly increasing over time (p < 0.001). The most productive countries and authors also accounted for high-quality publications and benefited from an active global network. The most productive journals derived from the field of pediatric surgery but accounted only for one-third of EA papers. The best cited journals were unspecific for pediatric surgery. Long-term outcome remained the most important topic in EA research, followed by surgical techniques, epidemiology, associated anomalies, perioperative complications, and postnatal management. In contrast, basic science was underrepresented. CONCLUSION Over the past seven decades, EA publications increased tremendously. Productiveness and quality benefited from global networking. Long-term outcome remains the key interest of EA research.

Abstract
Abstract
Introduction Congenital diaphragmatic hernia (CDH) is one of the most common congenital anomalies encountered by pediatric surgeons. With the advances in the pediatric minimal access surgery, its role in the repair of CDH has also increased. We have been using thoracoscopy for the repair for CDH since 2015. We herein report our experience of CDH repair in newborns.
Materials and Methods A retrospective review was conducted from July 2015 to December 2019 in the Department of Pediatric surgery after ethical approval from the institutional review board and included all the children with CDH who underwent thoracoscopic repair. The case records were used to assess the demographic details, type of defect, and early and late postoperative complications of thoracoscopy in CDH.
Results Thoracoscopic repair was attempted in 29 patients of CDH. Eight (27.5%) patients converted to open procedure and were excluded from the study. Primary closure of the diaphragmatic defect was performed in 90.4% (19) patients. Also, 9.5% (2) children required mesh repair. There was no intraoperative death. Postoperative ventilation was required in 57.1% (12) children. The mean time on the ventilator was 3.03 ± 0.9 days. The mean age of children requiring postoperative ventilation was less compared with children who were extubated in the postoperative period (p = 0.032). The median follow-up in our study was 12 months and 28.5% of patients developed recurrence of the diaphragmatic hernia. All the children underwent laparotomy and repair of the diaphragmatic defect.
Conclusion Thoracoscopic repair is a safe and effective option for the repair of CDH in children performed by surgeons with significant procedure experience.

[PMID: 32742058 PMCID: PMC7382772 DOI: 10.5455/aim.2020.28.84-93] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 04/19/2020] [Indexed: 12/13/2022] Open
Abstract
INTRODUCTION Certain methodological principles should be inexcusably followed when designing clinical or observational research to avoid bias and presentation of results that do not reflect the truth about the phenomenon that is the object of the study. AIM The aim of this study was to compare the methodological quality of clinical trials and observational studies published in medical journals from ex-Yugoslav countries indexed in Pubmed/MEDLINE. METHODS Clinical studies published in medical journals of ex-Yugoslav countries were retrieved from the Pubmed/MEDLINE database, and the sample for analysis was randomly chosen from the retrieved publications. The rate of the most common errors in the design of clinical/observational studies was established by a careful reading of the sampled publications and their checking against predefined criteria. RESULTS The studies published in two countries that are now member states of the European Union (Slovenia and Croatia) have significantly higher citation rates, impact factor, and methodological quality scores than studies from other ex-Yugoslav countries. While publications from Croatia show clear improvement trend throughout the last two decades, which is visible also in the last 10 years in Slovenia and Bosnia and Herzegovina, quality of clinical research published in journals from Serbia was stagnating in the same period. CONCLUSIONS There are significant differences in methodological quality and scientometric characteristics of clinical research published in medical journals of ex-Yugoslav countries that could be mitigated by more intensive training of clinical researchers in statistics and research design, as well as by more rigorous editorial practices.

JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2019; 26:201-210.

Abstract
Biliary atresia (BA) is a rare cholangiopathy of largely unknown etiology and unpredictable outcome. There has been an increasing number of BA-related publications, which may challenge researchers to determine their actual scientific value. This study aimed to evaluate the global research activity and developments relating to BA using a combination of scientometric methodologies and visualization tools. A comprehensive search strategy for the Web of Science™ database was designed to obtain bibliographic data on scientific BA publications for the timespan 1900-2018. Research output of countries, institutions, individual authors and collaborative networks was analyzed. Semi-qualitative research measures including citation rate and h-index were assessed. Choropleth mapping and network diagrams were used to visualize results. In total, 4,459 publications on BA were identified (88.5% in English), originating from 63 countries. The largest number was published by the USA (n = 991; 22.2%), Japan (n = 667; 15.0%) and the UK (n = 294; 6.6%). The USA combined the highest number of cooperation articles (n = 140). The most productive collaborative network was established between the USA and Canada (n = 17). Scientific papers from the UK received the highest average citation rate (16.7), whereas the USA had the highest country-specific h-index (59). Eighty-eight (2.0%) items were published under the auspices of multicenter consortiums and registries. The most productive institutions and authors were based in the USA, the UK, Japan, France, Canada and Taiwan. BA-related research has constantly been progressing, becoming more multidisciplinary but with main research endeavors concentrated in a few high-income countries. Studies into pathogenesis of BA remain uncommon, but are sorely needed to foster true scientific progress with this rare disease. Hence, international collaborative and translational research should be strengthened to allow further evolution in this field.

Abstract
Choledochal malformations (CMs) represent a spectrum of relatively rare and complex congenital anomalies, characterized by abnormal dilatation of the biliary tract in the absence of any acute obstruction. Today, almost 20% of CMs can be detected in-utero using maternal ultrasonography. Formal scientometric analysis was used to identify where modern CM research is taking place and perhaps where our attention should be directed in the future. Thus, this article offers a comprehensive review of recent scientific advances relating to CMs including the current understanding of etiology and classification, whilst also discussing key controversies such as risk of malignant transformation and the role of newer modalities of surgical treatment. Although laparoscopic excision of CMs and biliary reconstruction is nowadays feasible and safe, care should be taken before dispensing with standard open techniques, which have minimal complication rates and proven long-term benefit.

Global Evolution of Obesity Research in Children and Youths: Setting Priorities for Interventions and Policies. Obes Facts 2019; 12:137-149. [PMID: 30865948 PMCID: PMC6547288 DOI: 10.1159/000497121] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2018] [Accepted: 01/21/2019] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Childhood obesity has become a major global epidemic that causes substantial social and health burdens worldwide. The effectiveness of childhood obesity control and prevention depends largely on understanding the issue, including its current development and associated factors in a contextualized perspective. OBJECTIVES Our study aimed to gauge this kind of understanding. METHODS We systematically searched the Web of Science database for studies concerning child obesity published up to 2017 and analyzed the volume of publications, growth rates, impact scores, collaborations, authors, affiliations, and journals. A total of 57,444 research papers were included. RESULTS The three subject categories with the highest number of papers (over 3,000) were (1) nutrition and dietetics, (2) pediatrics, and (3) public, environmental, and occupational health. We found a dramatic increase in the amount of scientific literature on childhood obesity in the past one or two decades, led by scholars from the USA - ranking at the top regarding the total number of papers (23,965 papers; 30.8%) and total number of citations (859,793 citations) - and multiple Western countries where the obesity epidemic is prevalent. CONCLUSIONS The findings highlight the need for improving international and local research capacities and collaboration to accelerate knowledge production and translation into contextualized and effective childhood obesity prevention.
