Ann Surg Treat Res 2024; 106:178-187. [PMID: 38435491 PMCID: PMC10902624 DOI: 10.4174/astr.2024.106.3.178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 12/13/2023] [Accepted: 12/18/2023] [Indexed: 03/05/2024] Open
Abstract
Purpose Type 2 endoleaks (T2EL) are the most common form of endoleaks after endovascular aneurysm repair (EVAR). Several studies on the feasibility of embolization using ethylene vinyl alcohol copolymer (Onyx, Medtronic) for T2EL have been reported. The purpose of this study was to compare coil and Onyx embolization for T2EL treatment after EVAR. Methods Between August 2005 and July 2022, 46 patients underwent endovascular embolization for treatment of T2EL (15 Onyx and 31 coils). The primary endpoint was endoleaks resolution or significant aneurysm sac growth of >5 mm in maximal diameter after T2EL embolization. In addition, periprocedural factors, reintervention, sac rupture, and survival analysis were assessed. Results The follow-up period after embolization was significantly shorter in the Onyx group (11.6 months vs. 34.7 months, P = 0.016), and there was no difference in aneurysm sac growth rate between both groups (20.0% vs. 51.6%; P = 0.472, log-rank test). However, cases with multiple endoleak origins tended to be treated with Onyx (P = 0.002). When applying Onyx, there was no significant difference in results between the transarterial and translumbar approaches. Conclusion There appears to be no significant difference in the results of Onyx and coil embolization for T2EL treatment, although it is difficult to evaluate effectiveness due to the small number of cases and short follow-up period. However, in cases of multiple origin endoleaks or when the transarterial approach is not feasible, the Onyx by translumbar approach may be a more effective method.

A Single Center Review of a Total Transfemoral Approach to Upper Extremity Access in Branched and Fenestrated Physician Modified Endografts. Ann Vasc Surg 2022; 86:117-126. [PMID: 35809740 PMCID: PMC10339283 DOI: 10.1016/j.avsg.2022.05.041] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 05/29/2022] [Accepted: 05/30/2022] [Indexed: 12/20/2022]
Abstract
BACKGROUND Aortic aneurysms are normally treated by an endovascular approach. Due to the lack of devices and increasing experience, there is a growing number of complex aneurysms undergoing repair by physician modified endografts (PMEGs). Previously, our practice was to target visceral vessels exclusively through upper extremity access. We have since then shifted to an all transfemoral approach when possible. This study aims to show the operative benefits of transfemoral only approaches. METHODS Patients who underwent a PMEG at a tertiary center between 2015 and 2020 were included. Patients were stratified into 2 groups based on branched vessel approach-transfemoral only versus axillary or composite (axillary and femoral). Forty-one patients had a pararenal or type IV thoracoabdominal aortic aneurysm (TAAA) and 15 patients had more complex TAAA. Primary outcomes were operative time, radiation exposure, fluoroscopy time, contrast, and blood loss. Secondary outcomes were 30-day mortality and major adverse events. Linear regression models were used to evaluate the association between approach type and the main outcomes. RESULTS Fifty-six patients were included with 48% (n = 27) in the transfemoral group and 52% (n = 29) in the axillary/composite group. Baseline characteristics were similar between the groups. Intraoperative outcomes revealed significant increase in the average operative time (418 vs. 246 min, P < 0.001), in radiation exposure (2,755 vs. 1,740 mGy, P = 0.03), in fluoroscopy time (108 vs. 74 min, P = 0.01) and in blood loss (579 vs. 202 cc, P = 0.002) in the axillary/composite group compared to the transfemoral group. There was no significant difference in 30-day mortality or major adverse events including stroke. CONCLUSIONS This study shows a transfemoral approach to complex endovascular aortic aneurysm repair as opposed to axillary/composite approach has decreased operative time, radiation exposure, and fluoroscopy time and no significant differences in 30-day mortality or major adverse events. When treating complex aneurysms, improving efficiency is important to minimize morbidity to patients and operators.

Abstract
Hallux valgus (HV) is a very common deformity among foot disorders, therefore attracting strong interest from foot and ankle surgeons. We investigated publication trends on HV in the literature. The analysis was conducted through an electronic search of the Web of Science database for publications between 1999 and 2019, studying the data of origin through bibliometrics. The following search string was utilized: TI = (hallux valgus* OR hallux abductovalgus*) with filters for the English language and documents in article format. The "Bibliometrix" package of R software was used for the bibliometric analysis, and the VOSviewer was used to create graphs. A total of 789 articles were found in the electronic search, with 2,723 cited articles. The most common Web of Science category was Orthopedics (83.0%), and Coughlin M.J. was the main researcher in this field with the largest number of publications (17). The United States led in terms of the number of published articles (26.7%). An increase in the number of publications over time was noted, with 2016 being the year with the highest number of articles (78). The journal with the most articles was Foot and Ankle International, with 35.2% of the publications. The number of published studies on HV has increased rapidly since 2012. The United States ranks first in related research worldwide. The journal with the most articles was Foot and Ankle International.

Thematic research clusters in very old populations (≥ 80 years): a bibliometric approach. BMC Geriatr 2021; 21:266. [PMID: 33882849 PMCID: PMC8058755 DOI: 10.1186/s12877-021-02209-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 03/25/2021] [Indexed: 12/17/2022] Open
Abstract
Background Population aging will be one of humanity’s major challenges in the decades to come. In addition to focusing on the pathologies causing the greatest mortality and morbidity in this population, such as dementia, health research in elderly people must consider a myriad of other interlinked factors, such as geriatric syndromes, social aspects, and factors related to preserving quality of life and promoting healthy aging. This study aims to identify the main subject areas attracting research attention with regard to very old (≥ 80 years) populations. Methods Documents assigned with the medical subject heading “Aged, 80 and over” were retrieved from MEDLINE and the Web of Science. This dataset was used to determine publication output by disease, geographic region, country, and discipline. A co-word analysis was undertaken to identify thematic research clusters. Results Since the mid-2000s, there has been a boom in scientific output focusing specifically on very old populations, especially in Europe (43.7% of the documents) but also in North America (30.5%) and Asia (26%); other regions made only nominal contributions (0.5 to 4.4%). The USA produced the most research, while the most growth over the study period occurred in Japan, Spain, and China. Four broad thematic clusters were identified: a) geriatric diseases, health services for the aged, and social and psychological issues of aging; b) cardiovascular diseases; c) neoplasms, and d) bacterial infections & anti-bacterial agents. Conclusions Scientific research in very old populations covers a wide variety of interrelated topics. In quantitative terms, the top subject areas have to do with cardiovascular and cerebrovascular diseases (including aortic valve stenosis and stroke), dementia, and neoplasms. However, other degenerative pathologies, geriatric syndromes, and different social and psychosocial aspects also attract considerable interest. It is necessary to promote more equal participation in global research on pathologies and topics related to very elderly populations, as the highest rates of population aging and the largest numbers of elderly people in the next decades will be in low- and middle-income countries.

Abstract
BACKGROUND In recent years, the number of women who are pregnant again with the history of cesarean section, has increased year by year in China. Scarred uterine attracts much attention due to its particularity. This study aimed to understand the knowledge domain and development trends of scarred uterus after cesarean section. METHODS Data were obtained from the Web of Science Core Collection databases (WoSCCd) including SSCI and SCI-Expanded. We carried out a comprehensive literature retrieval using index words as follows: "TI=((((prior) OR (previous) OR (after) OR (post)) AND ((cesarean) OR (caesarean))) OR (scarred uterus) OR ((uterine) AND ((scar) OR (scarring) OR (wound))))". The time interval for the search was from 1999 to 2018, totally 20 years. A document type was only article and the language of article was English. All electronic searches were performed on 15 May 2019. CiteSpace, HistCite, and VOSviewer software were used to facilitate the analysis. RESULTS The analysis included 1938 bibliographic records. The annual number of publications exhibited the solid increase. A total of 84 countries contributed to the overall published output during the study period. USA published the highest number of publications (n = 508, 26.2%), which also had the highest total global citation score (10,826). American Journal of Obstetrics and Gynecology, Obstetrics and Gynecology, and Journal of Maternal-fetal & Neonatal Medicine were the top three journals that published the articles. The top 10 productive institutions, such as Northwestern University, Tel Aviv University, and Karolinska Institute were located mainly in USA, Israel, and Sweden, and top 10 authors originated totally from USA. Vaginal birth after cesarean, uterine rupture, painless labor, and scar pregnancy were research hotspots and may be promising in the next few years. CONCLUSIONS This bibliometrics provides a comprehensive analysis that delineates the scientific productivity, collaboration, and research hotspots about scarred uterus after cesarean section, which is very helpful to focus on the future research direction.

Abstract
BACKGROUND Pediatric surgery remains the most competitive general surgery subspecialty. The authors suspected significant inflation in academic metrics since the last published paper. This study aimed to identify factors associated with applicant success in the match. METHODS After IRB approval, all applications to a single accredited pediatric surgery fellowship program were reviewed for match years 2014-2018. Matched and unmatched applicants were compared in an unadjusted and adjusted analysis. RESULTS This training program received 414 of 425 total applications (97%). Match results were available for 388 (94%). Matched applicants were more likely to train in programs with pediatric surgery fellowships (64% vs. 28%) and to have dedicated research time (55% vs. 21%; all p < 0.01). Matched applicants had more total publications (median: 12 vs. 7, p < 0.01) and higher ABSITE scores (median: 64th vs. 59th percentile, p < 0.01). Training in multiple programs negatively impacted the chance to match (p < 0.01). The median number of publications per applicant increased over the study time period from 7 to 11 (p < 0.01). CONCLUSIONS The likelihood of matching into a pediatric surgery fellowship was related to the type of residency attended, dedicated research time, ABSITE scores, and number of publications. Overall, the total number of publications reported by all applicants increased. TYPE OF STUDY Retrospective Comparative Study. LEVEL OF EVIDENCE Level III.
