AI Article Synopsis
- Patients with chronic venous ulceration (CVU) and varicose veins (VV) show a higher prevalence of thrombophilia compared to matched controls without venous disease.
- This study tested various factors related to blood clotting in 27 VV patients, 27 CVU patients, and 54 controls, revealing that those with CVU have the highest rates of multiple thrombophilic conditions.
- The findings indicate that thrombophilia may increase the risk of developing venous issues like VV and CVU, suggesting a possible link between these conditions and abnormal blood clotting.
Article Abstract
Background: Uncontrolled studies suggest that patients with chronic venous ulceration (CVU) have an increased prevalence of thrombophilia, similar to that observed in patients with deep vein thrombosis. This study compared the nature and prevalence of thrombophilia in patients with varicose veins (VV, CEAP clinical [C] grade C(2) to C(3)) and patients with CVU (C(5) to C(6)) with an age- and sex-matched population without clinical or duplex ultrasound evidence of venous disease.
Methods: Twenty-seven patients with VV, 27 patients with CVU, and 54 age- and sex-matched case controls with no clinical or duplex evidence of lower limb venous disease, underwent testing for factor V Leiden and prothrombin 20210A mutations, antithrombin deficiencies, and levels of antiphospholipid antibodies, homocysteine, protein C and S, and factor VIII, IX, and XI.
Results: The overall prevalences of single and multiple thrombophilias were significantly higher in cases than in controls. Specifically, in VV patients, the prevalences of no, single, and multiple thrombophilias were 33%, 52%, and 15%, respectively, compared with 63%, 26%, and 11% in VV controls. In CVU patients, the prevalences of no, single, and multiple thrombophilias was 26%, 30%, and 44%, respectively, compared with 66%, 22%, and 11% in CVU controls. Compared with controls, only factor XI levels were significantly higher in VV patients, and homocysteine and factor VIII, IX, and XI levels were all significantly higher in CVU patients.
Conclusion: Patients with VV, and particularly CVU, have significantly higher prevalences of single and multiple thrombophilias than age- and sex-matched controls without clinical or duplex evidence of lower limb venous disease. These data support the hypothesis that thrombophilia predisposes to the development of superficial and deep lower limb venous reflux, and so VV and CVU, through the increased occurrence of clinical and subclinical thrombosis.

Correlates of Cetuximab Efficacy in Recurrent and Metastatic Head and Neck Squamous Cell Carcinoma Previously Treated With Immunotherapy.
JCO Precis Oncol

Department of Medicine, Massachusetts General Hospital, Boston, MA.
Purpose: Immune checkpoint inhibitors (ICIs) are now first-line therapy for most patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), and cetuximab is most often used as subsequent therapy. However, data describing cetuximab efficacy in the post-ICI setting are limited.
Methods: We performed a single-institution retrospective analysis of patients with R/M HNSCC treated with cetuximab, either as monotherapy or in combination with chemotherapy, after receiving an ICI.
Poor Olfaction and Risk of Stroke in Older Adults: The Atherosclerosis Risk in Communities Study.

Department of Epidemiology and Biostatistics, College of Human Medicine, Michigan State University, East Lansing (K.W.C., C.L., Z.L., M.R., H.C.).
Background: Poor olfaction may be associated with adverse cerebrovascular events, but empirical evidence is limited. We aimed to investigate the association of olfaction with the risk of stroke in the Atherosclerosis Risk in Communities Study.
Methods: We included 5799 older adults with no history of stroke at baseline from 2011 to 2013 (75.
Alternative approaches for monitoring and evaluation of lymphatic filariasis following mass drug treatment with ivermectin, diethylcarbamazine and albendazole in East New Britain Province, Papua New Guinea.
PLoS Negl Trop Dis
January 2025
Department of Pathology, Center for Global Health and Disease, Case Western Reserve University, Cleveland, Ohio, United States of America.
Background: WHO recommends two annual rounds of mass drug administration (MDA) with ivermectin, diethylcarbamazine, and albendazole (IDA) for lymphatic filariasis (LF) elimination in treatment naïve areas that are not co-endemic for onchocerciasis such as Papua New Guinea (PNG). Whether two rounds of MDA are necessary or sufficient and the optimal sampling strategies and endpoints for stopping MDA remain undefined.
Methods And Findings: Two cross-sectional studies were conducted at baseline (N = 49 clusters or villages) and 12 months after mass drug administration (MDA) with IDA (N = 47 villages) to assess lymphatic filariasis (LF) by circulating filarial antigenemia (CFA) and microfilariae (Mf).
Antiretroviral therapies and status of people living with HIV in Japan: An update from hospital survey and national database.
PLoS One

Department of Infectious Diseases, NHO Nagoya Medical Center, Nagoya, Aichi, Japan.
No updated data on people living with HIV (PLHIV) in Japan have been available since 2015, leaving a critical gap in understanding the current status of care and treatment. Therefore, this study aimed to conduct a nationwide evaluation of the second and third goals of the "90-90-90 target" defined by UNAIDS between 2016 and 2020. The study utilized data from approximately 360 core hospitals through structured questionnaires and the National Database of Health Insurance Claims and Specific Health Checkups (NDB).
