Cannabis use and atherosclerotic cardiovascular disease outcomes: A meta-analysis of multinational cohort data.
While an association between cannabis use and the risk of atherosclerotic cardiovascular diseases (ASCVD) has been reported numerous times, it remains inconclusive as to whether this link is causal in nature. We sought to consolidate data from observational studies to explore the association between ever use of cannabis and ASCVD outcomes, including myocardial infarction, stroke, and a combined measure of any adverse cardiovascular events in comparison to non-users or controls. ⋯ The evident statistical correlations between cannabis use and adverse cardiovascular outcomes underscore its potential as a risk factor for cardiovascular disease, suggesting plausibility for a causal relationship between cannabis use and ASCVD. With rising trends in medical cannabis use and cannabis use disorder across age demographics, heightened risk awareness and informed decision-making regarding cannabis consumption are critical priorities in healthcare and public health initiatives.

Tadalafil is a selective phosphodiesterase type 5 (PDE5) inhibitor commonly used for the treatment of erectile dysfunction and benign prostatic hyperplasia. Its mechanism of action involves the inhibition of PDE5, leading to increased levels of nitric oxide and cyclic guanosine monophosphate in the corpus cavernosum, which facilitates smooth muscle relaxation. This article reviews studies using tadalafil in the treatment of cardiovascular diseases and emphasizes its potential advantages in conditions such as pulmonary arterial hypertension, atherosclerosis, coronary artery disease, myocardial infarction, heart failure, stroke, diabetic ulcers, and cardiomyopathy. Although tadalafil shows potential efficacy in treating cardiovascular disease, further experimental studies are needed to clarify its pharmacological effects on cardiovascular protection beyond PDE5 inhibition.

Bridging thrombolysis versus direct endovascular treatment in acute vertebrobasilar artery complex occlusion.
Endovascular treatment (EVT) is an effective treatment for patients with acute vertebrobasilar artery complex occlusion (VBAO). However, the benefit of bridging thrombolysis prior to EVT remains controversial. The purpose of the present study is to explore the best treatment strategy between bridging treatment (BT) and direct EVT in patients with acute VBAO. ⋯ This matched-control study and meta-analysis suggest that compared with direct EVT, BT may be associated with better functional outcomes in patients with acute VBAO treated within 24 hours of estimated occlusion.

The Role of Processed Electroencephalography in the Detection and Management of Acute Cerebral Ischemia: A Scoping Review.
Processed electroencephalography (pEEG) is increasingly used to titrate the depth of anesthesia. Whether such intra-procedural pEEG monitoring can offer additional information on cerebral perfusion or acute focal or global cerebral ischemia is unknown. This scoping review aimed to provide a narrative analysis of the current literature reporting the potential role of pEEG in adults with acute cerebral ischemia. ⋯ Low sensitivity associations between pEEG indices and cerebral blood flow were highlighted, which may be influenced by cerebral autoregulatory thresholds. Despite the associations reported in observational studies, this review identified significant uncertainty in the role of pEEG during cerebral ischemia. There is a paucity of high-level observational (cohort or case-control) or randomized trial research examining the possible role of pEEG for the detection and management of cerebral ischemia during acute stroke, including during endovascular therapy, or in other common scenarios of acute cerebral ischemia.

Advances in diagnostic imaging and interventional treatment of aphasia after basal ganglia stroke.
Post-stroke basal ganglia aphasia is an unusual and transient form of aphasia resulting from basal ganglia damage. It is commonly believed that the generation of language function primarily resides in regular language regions of the brain; however, recent findings indicate a prevalence of basal ganglia stroke aphasia as high as 22%. Subcortical structures (e.g., basal ganglia) also play an important role in language processing. ⋯ Treatment for post-stroke basal ganglia aphasia includes transcranial magnetic stimulation, a recent emerging therapeutic technique, in addition to conventional medications and speech rehabilitation. Consequently, understanding this condition is crucial. This review delves into its causes, imaging methods, and therapeutic interventions, offering a systematic and comprehensive analysis of these aspects.
