Monoclonal antibodies neutralizing alpha-hemolysin, bicomponent leukocidins, and clumping factor A protected against Staphylococcus aureus-induced acute circulatory failure in a mechanically ventilated rabbit model of hyperdynamic septic shock
ConclusionThese results demonstrate the potential utility of a mechanically ventilated rabbit model that reproduced hallmark clinical features of hyperdynamic septic shock and the translational potential of immunotherapy targeting S. aureus virulence factors for the prevention of staphylococcal septic shock.

A Case of Infective Endocarditis Caused by Streptococcus sanguinis Resulting in Stroke, Ruptured Infected Pseudoaneurysm of Superior Mesenteric Artery, and Rapidly Progressive Glomerulonephritis
Intern Med. 2023 Jun 21. doi: 10.2169/internalmedicine.2017-23. Online ahead of print.ABSTRACTA 71-year-old-man was admitted to our hospital with a cerebral embolism and diagnosed with infective endocarditis (IE) caused by Streptococcus sanguinis. Mitral valve replacement was performed. About one month later, he experienced sudden abdominal pain and shock due to a ruptured infected mesenteric artery pseudoaneurysm. Forty-four days after abdominal surgery, he presented with rapidly progressive glomerulonephritis with anti-glomerular basement membrane antibodies. He was treated with plasma exchange and prednisolone, and his ...

Lyme neuroborreliosis: Progressive cerebral vasculitis responsive to cyclophosphamide. A case report and review of the literature
Less than 1 % of patients with Lyme Neuroborreliosis (LNB) present with a cerebrovascular event. Ischaemic strokes occur more commonly than parenchymal or subarachnoid haemorrhages. If cerebral vasculitis due to LNB is suspected, antibiotic treatment should be started immediately, which will normally lead to remission. Very rarely progression and recurrent strokes are observed despite sufficient antibiotic therapy, even if steroids are added. Currently there are no guidelines on the adequate treatment of cerebral vasculitis due to LNB which is not responsive to antibiotics and steroids, but in very few reported cases cyclo...

Gut microbes in cerebrovascular diseases: Gut flora imbalance, potential impact mechanisms and promising treatment strategies
The high morbidity, mortality, and disability rates associated with cerebrovascular disease (CeVD) pose a severe danger to human health. Gut bacteria significantly affect the onset, progression, and prognosis of CeVD. Gut microbes play a critical role in gut-brain interactions, and the gut-brain axis is essential for communication in CeVD. The reflection of changes in the gut and brain caused by gut bacteria makes it possible to investigate early warning biomarkers and potential treatment targets. We primarily discussed the following three levels of brain-gut interactions in a systematic review of the connections between g...

Streptococcus Agalactiae Meningitis Presented with Cerebral Infarction in Adult Patient & #8211; Clinical Case and Review
Conclusions: CI is a rare adverse effect of neuro infections leading to an even worse clinical outcome. Early recognition of the infection and appropriate antimicrobial therapy are the crucial moments of successful management of GBS disease.

Artery of Percheron Occlusion in China: A Case Report and Chinese Literature Review
Conclusion: Our report suggests that unusual mood disorder and language disorder of aged patients might indicate the AOP occlusion, and cerebral imaging of magnetic resonance imaging (better with magnetic resonance angiography) should be performed to establish the diagnosis of AOP occlusion. The fast and accurate diagnosis of stroke because of AOP occlusion could best benefit the patients.

Intramedullary spinal cord abscess associated with right-to-left shunt via right superior vena cava draining into left atrium: A case report
We report the first case of ISCA associated with RSVC-LA RL shunt. Patient concerns: A 36-year-old man developed progressive paraparesis, dysuria, and spontaneous pain in the lumbar region and lower extremities. Spinal magnetic resonance imaging revealed an intramedullary lesion extended from Th12 to L2 with ring-shaped gadolinium enhancement. Cerebrospinal fluid (CSF) study exhibited a marked pleocytosis, and CSF culture grew Streptococcus intermedius. Cardiovascular computed tomography angiography identified RSVC-LA RL shunt, which caused transient acute cardiac syndrome due to air embolus. Diagnoses: The p...

Hypersensitive C ‐reactive protein‐albumin ratio is associated with stroke‐associated pneumonia and early clinical outcomes in patients with acute ischemic stroke
ConclusionsPatients with AIS with a high CAR at admission are more likely to develop SAP during hospitalization and have poor short-term clinical outcomes. These findings might help to timely identify patients at high risk of SAP and provide a basis for further research on prophylactic antibiotic therapy.

Very early infective endocarditis after transcatheter aortic valve replacement
ConclusionA significant proportion of IE episodes following TAVR occurs within a few weeks following the procedure and are associated with dismal outcomes. Some baseline and TAVR procedural factors were associated with VE-IE, andStaphylococcus aureus and enterococci were the main causative pathogens. These results may help to select the more appropriate antibiotic prophylaxis in TAVR procedures and guide the initial antibiotic therapy in those cases with a clinical suspicion of IE.Graphical abstractVery early infective endocarditis after trans-catheter aortic valve replacement. VE-IE indicates very early infective endocard...
