    Abstract Objective To use bibliometric analysis to understand characteristics and trends in the research on chronic venous disease (CVD), which affects patients’ quality of life by causing pain, swelling, and ulceration. Methods We searched the Thomson Reuters Web of Science citation indexing database to identify the 100 most-cited manuscripts on CVD. The resulting articles were analyzed by title, author, institution, topic, year of publication, and country of origin. Results The Journal of Vascular Surgery published the most manuscripts on CVD (n = 36) and was the most-cited journal (n = 5356). The United Kingdom was the country with the greatest number of publications (n = 32). Imperial College London was the institution with the highest number of publications (n = 6). Endovenous thermal ablation was the most widely studied research specialty (n = 30). Conclusions Our analysis showed that the majority of CVD research is carried out in Western countries, and that the number of research studies is increasing in line with recent advances in CVD.

  2. Article ; Online: Recurrent thrombosis of splanchnic and lower extremity arteries with essential thrombocythemia

    Abstract Essential thrombocythemia is a myeloproliferative neoplasm characterized by platelet aggregation and thrombosis. Clinically, essential thrombocythemia increases the risk of both thrombosis and bleeding. Essential thrombocythemia is more involved in micro- and small-sized arteries than in large arteries. Many essential thrombocythemia patients exhibit various symptoms, including microvascular thrombosis with acute coronary disease, digital ischemia, and transient ischemic attack. This study reports a rare case of recurrent thrombosis in relatively large vessels including splanchnic, lower extremity arteries, and aorta in essential thrombocythemia. A 70-year-old woman was admitted to the emergency room with abdominal pain and fever for a day. The patient underwent three operations due to recurrent arterial thrombosis of superior mesenteric, splenic, aorta, and lower extremities. She had recurrent diarrhea and acute kidney injury because of short bowel syndrome after extensive bowel resection. In conclusion, essential thrombocythemia patients aged >60 years and who have risk factors such as history of major ischemic events or severe leukocytosis must be careful of thrombosis of the medium- and large-sized arteries, including splanchnic and lower extremity arteries.

    Abstract Little is known about the time-varying risk factors for fractures in kidney transplant recipients (KTRs). Using the Korea Organ Transplantation Registry, a nationwide cohort study of KTRs, the incidence, locations, and time-varying predictors of fractures were analyzed, including at baseline and post-transplant 6-month variables in KTRs who underwent KT between January 2014 and June 2019. Among 4134 KTRs, with a median follow-up of 2.94 years (12,441.04 person-years), 63 patients developed fractures. The cumulative 5-year incidence was 2.10%. The most frequent locations were leg (25.40%) and foot/ankle (22.22%). In multivariable analysis, older recipient age at baseline (hazard ratio [HR], 1.035; 95% confidence interval [CI], 1.007–1.064; p = 0.013) and higher tacrolimus trough level (HR, 1.112; 95% CI, 1.029–1.202; p = 0.029) were associated with higher risks for fractures. Pretransplant diabetes mellitus had a time-dependent impact on fractures, with increasing risk as time elapses (HR for diabetes mellitus 1.115; 95% CI, 0.439–2.832; HR for diabetes mellitus × time, 1.049; 95% CI, 1.007–1.094; p = 0.022). In conclusion, KTRs had a high risk of peripheral skeletal fractures in the first 5 years. At baseline recipient age, pretransplant diabetes mellitus and tacrolimus trough level after KT were responsible for the fractures in KTRs.

    Abstract To overcome organ shortage, expanded criteria donors, including elderly deceased donors (DDs), should be considered. We analyzed outcomes of kidney transplantation (KT) from elderly DDs in a nationwide study. In total, data of 1049 KTs from DDs using the database of Korean Organ Transplantation Registry (KOTRY) were retrospectively analyzed based on the age of DDs: age ≥60 years vs. <60 years. Clinical information, graft status, and adverse events were reviewed in DDs and recipients. The mean age of the 1006 DDs was 51.04±10.54 years, and 21.5% of donors were aged ≥60 years. Elderly DDs had a significantly higher prevalence of diabetes and hypertension and higher Kidney Donor Risk Index (KDRI) and Kidney Donor Profile Index (KDPI). The mean age of the recipients was 47.45±14.87 years. Patients who received KT from elderly DDs were significantly older (53.12±15.14 vs. 45.88±14.41, P<0.001) and had a higher rate of diabetes (41.9 vs. 24.4%, P<0.001). Graft outcomes were not significantly different. Renal function was similar between the groups at the time of discharge and at 6 months, 1 year, and 2 years after KT. The rate of delayed graft function (DGF) was not significantly different. Risk factors of DGF were significantly different in DDs aged ≥60 years and <60 years. In the multivariable model, male sex (odds ratio: 3.99, 95% confidence interval: 1.42-11.22; P = 0.009) and KDRI (12.17, 2.23-66.34; P = 0.004) were significant risk factors for DGF in DDs aged ≥60 years. In DDs aged <60 years, thymoglobulin induction (2.62, 1.53-4.48; P<0.001) and continuous renal replacement therapy (3.47, 1.52-7.96; P = 0.003) were significant factors. Our data indicated that graft outcomes, including renal function and DGF, were similar for elderly DDs and DDs aged <60 years. Elderly DDs might be considered tolerable donors for KT, with active preoperative surveillance.
