Chagas disease stroke and associated risk factors: A case-control study

Eduardo Sousa de Melo, Rodrigo de Paiva Bezerra, Arthur Cesario de Holanda, Maria Junia Lira e Silva, Paloma Peter Travassos, Tayne Fernanda Lemos da Silva, Genova Maria de Azevedo Oliveira, Silvia Marinho Martins Alves, Carolina de Araujo Medeiros, Maria das Neves Dantas da Silveira Barros, Wilson Alves de Oliveira, Gisele Sampaio Silva, Luciana Patrizia Alves de Andrade Valenca

Summary: Cardiac involvement has been found to be the predominant factor correlated with stroke in Chagas disease. While atherosclerosis-related risk factors are prevalent, their influence on ischemic stroke in Chagas disease appears limited.

Adhesive properties of plasma-circulating and platelet-derived microvesicles from healthy individuals

E. O. Artemenko, S. I. Obydennyi, K. S. Troyanova, G. A. Novichkova, D. Y. Nechipurenko, M. A. Panteleev

Summary: In this study, we investigated the adhesive properties of circulating plasma-derived and platelet-derived microvesicles (MVs) and their potential role in thrombus growth. The results showed that both types of MVs weakly bound fibrinogen but did not stably adhere to immobilized fibrinogen. Moreover, the presence of these MVs did not significantly affect thrombus formation. Therefore, MVs present in the plasma of healthy individuals are unlikely to directly contribute to thrombus formation under arterial flow conditions.

Astrocytic expression of Yes-associated protein (YAP) regulates retinal neovascularization in a mouse model of oxygen-induced retinopathy

Zhifei Liu, Jieqiong Zhang, Xue Li, Qiumei Hu, Xi Chen, Linlin Luo, Liqianyu Ai, Jian Ye

Summary: The study revealed that astrocytic YAP can alleviate retinal pathological angiogenesis by inhibiting overactivation of astrocytes, thereby suppressing excessive VEGF-A production and neuroinflammation.

Differences in peripheral microcirculatory blood flow regulation in chronic kidney disease based on wavelet analysis of resting near-infrared spectroscopy

Jingting Yao, Justin D. Sprick, Jinhee Jeong, Jeanie Park, David A. Reiter

Summary: This study used time-frequency spectral analysis of resting near-infrared spectroscopy (NIRS) signals to evaluate the regulation of peripheral microvascular perfusion in CKD patients. The findings suggest that CKD patients have impaired neurogenic and endothelial functions, which may be associated with increased sympathetic activity and reduced endothelial function in CKD.

Thrombotic triad in microgravity

Mohammad M. Elahi, Alexandra N. Witt, Edward L. G. Pryzdial, Paul B. McBeth

Summary: Thrombotic disease may be underdiagnosed in microgravity conditions, and the underlying factors are still poorly understood. A case of internal jugular vein thrombosis was recently diagnosed in a low-risk female astronaut, and six out of ten additional crew members showed risk factors for jugular venous flow. Observations in space and studies on Earth suggest that microgravity affects blood flow, coagulation, and vascular function.

Trimethylamine-N-oxide (TMAO) and basic fibroblast growth factor (bFGF) are possibly involved in corticosteroid resistance in adult patients with immune thrombocytopenia

Lei Liu, Huifang Xu, Jian Wang, Haiyan Wang, Saisai Ren, Qian Huang, Mingyan Zhang, Hui Zhou, Chunyan Yang, Lu Jia, Yu Huang, Hao Zhang, Yanling Tao, Ying Li, Yanan Min

Summary: This study investigated the gut microbiota metabolites and cytokines, chemokines, and growth factors in patients with ITP and found their association with treatment responsiveness. The findings suggest that imbalanced secretion of cyto(chemo)kins/growth factors and inadequate levels of TMAO are characteristic of patients with ITP.

Driver gene KRAS aggravates cancer-associated stroke outcomes

Haomin Yan, Tsutomu Sasaki, Yasufumi Gon, Kumiko Nishiyama, Hideaki Kanki, Hideki Mochizuki

Summary: The incidence of cancer-associated stroke has increased with the prolonged survival times of cancer patients. In this study, the researchers focused on the driver gene KRAS and found that KRAS mutations exacerbated neurological deficits after stroke and promoted tumor growth. They also identified the upregulation of pro-inflammatory responses and the promotion of STAT3 phosphorylation in mice with KRAS mutations. Additionally, the researchers found that colorectal cancer patients with stroke onset within 3 months after cancer diagnosis had a worse prognosis.

Shock score for prediction of clinical outcomes among stable patients with acute symptomatic pulmonary embolism

Marta Najarro, Winnifer Briceno, Carmen Rodriguez, Alfonso Muriel, Sara Gonzalez, Ana Castillo, Ignacio Jara, Parth Rali, Catalin Toma, Behnood Bikdeli, David Jimenez

Summary: The CPES score is a useful tool in identifying the risk of hemodynamic deterioration in normotensive patients with acute PE, with acceptable C-statistic, excellent specificity, and low positive predictive value.

One year clinical outcome of dual anti-platelet therapy with the Novel Ticagrelor plus Aspirin versus Clopidogrel plus Aspirin for Endovascular Intervention of patients with Intracranial Aneurysm: A meta-analysis

Yunxia Zhou, Shenglan He, Yanhong Hu

Summary: Compared with clopidogrel, DAPT with ticagrelor plus aspirin was associated with significantly lower thromboembolic events without an increase in hemorrhagic events in the treatment of intracranial aneurysms, according to the one-year clinical outcome analysis. However, larger upcoming trials are needed to confirm the effectiveness and safety of ticagrelor-associated DAPT.

Summary: This study utilized an in vitro biomimetic experimental system to investigate the transvascular transport of nano-preparations, and found that the pressure gradient between vascular fluid pressure and interstitial fluid pressure determines the existence of the enhanced penetration and retention effect of nanopreparations.

A qualitative study of barriers and facilitators to using tenecteplase to treat acute ischemic stroke

Sidarrth Prasad, Erica M. Jones, Mehari Gebreyohanns, Veronica Aguilera, DaiWai M. Olson, Jane A. Anderson, Sean I. Savitz, Salvador C. Flores, Steven J. Warach, Charlotte E. Rhodes, Mark P. Goldberg, Nneka L. Ifejika

Summary: This study identified the barriers and facilitators to adopting tenecteplase (TNK) as a thrombolytic treatment for acute ischemic stroke (AIS) by conducting qualitative research with stroke clinicians in Texas. The findings suggest that providing evidence and identifying key change processes can help clinicians achieve consensus on adopting TNK for AIS treatment.

Harnessing the benefits of glycine supplementation for improved pancreatic microcirculation in type 1 diabetes mellitus

Bing Wang, Xiaohong Song, Xu Zhang, Yuan Li, Mengting Xu, Xueting Liu, Bingwei Li, Sunjing Fu, Hao Ling, Yingyu Wang, Xiaoyan Zhang, Ailing Li, Mingming Liu

Summary: This study found that glycine supplementation can improve pancreatic microcirculation in T1DM mice and reverse the production of inflammatory cytokines. Furthermore, glycine supplementation also alleviates damage to pancreatic islet and vascular tissues, suggesting a potential therapeutic effect for T1DM.

An examination of geographic access to outpatient stroke rehabilitation services in Tennessee, a stroke belt state

Phoebe M. Tran, Cenjing Zhu, William T. Harris II, Sajeesh K. Kamala Raghavan, Agricola Odoi, Liem Tran

Summary: This study assessed the geographic accessibility of stroke rehabilitation facilities in Tennessee. The study found that rural counties had significantly longer travel distances and times compared to urban counties. Counties with high and medium stroke prevalence also had higher travel times and distances compared to low stroke prevalence counties. Therefore, addressing transportation barriers and implementing tele-rehabilitation are crucial for improving access to stroke aftercare in these areas.
