Antimicrobial resistance is one of the critical public health issues in the world. There is an urgent need to develop effective broad-spectrum antibiotics to treat the infection of multi-drug resistant Gram-negative bacilli. Cefiderocol, developed by the Shionogi Inc. in Japan, is a new type of iron carrier cephalosporin antibiotics, which overcomes the drug resistance of Gram-negative bacilli due to the down-regulation of outer membrane pore protein and the up-regulation of efflux pump, and has good stability to serine- and metallo-carbapenemases. This drug has a broad spectrum and strong antibacterial activity against carbapenem-resistant Enterobacteriaceae (CRE), Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia. Cefiderocol can be used to treat complex urinary tract infections (including pyelonephritis), hospital-acquired pneumonia, and ventilator-associated pneumonia. By summarizing the chemical structure, antibacterial mechanism, in vitro antibacterial activity, pharmacokinetics, pharmacodynamics, and clinical treatment of cefiderocol, this review shows the application potential of cefiderocol as a new iron carrier cephalosporin in the treatment of multi-drug resistant Gram-negative bacilli infections.

INTRODUCTION:
A second-tier rapid response team (RRT) is activated for patients who do not respond to first-tier measures. The premise of a tiered response is that first-tier responses by a ward team may identify and correct early states of deterioration or establish goals of care, thereby reducing unnecessary escalation of care to the RRT. Currently, utilisation and outcomes of tiered RRTs remain poorly described.
METHODS:
A prospective observational study of adult patients (age ≥18 years) who required RRT activations was conducted from February 2018 to December 2019.
RESULTS:
There were 951 consecutive RRT activations from 869 patients and 76.0% patients had a National Early Warning Score (NEWS) ≥5 at the time of RRT activation. The majority (79.8%) of patients required RRT interventions that included endotracheal intubation (12.7%), point-of-care ultrasound (17.0%), discussing goals of care (14.7%) and intensive care unit (ICU) admission (24.2%). Approximately 1 in 3 (36.6%) patients died during hospitalisation or within 30 days of RRT activation. In multivariate analysis, age ≥65 years, NEWS ≥7, ICU admission, longer hospitalisation days at RRT activation, Eastern Cooperative Oncology Group performance scores ≥3 (OR [odds ratio] 2.24, 95% CI [confidence interval] 1.45-3.46), metastatic cancer (OR 2.64, 95% CI 1.71-4.08) and haematological cancer (OR 2.78, 95% CI 1.84-4.19) were independently associated with mortality.
CONCLUSION
Critical care interventions and escalation of care are common with second-tier RRTs. This supports the need for dedicated teams with specialised critical care services. Poor functional status, metastatic and haematological cancer are significantly associated with mortality, independent of age, NEWS and ICU admission. These factors should be considered during triage and goals of care discussion.

Objective To analyze the status and development direction of acupuncture treatment for vascular dementia from 2003 to 2023;To provide reference for related research.Methods Relevant literature on acupuncture treatment for vascular dementia was retrieved from CNKI,Wanfang Data,and VIP from January 2003 to September 2023.NoteExpress 3.7.0 and CiteSpace 5.7.R5 software were used to analyze keywords,authors,research institutions,and visualize knowledge maps.Results A total of 934 articles were included in the analysis,showing a slow fluctuating upward trend in publication volume.The study involved 653 authors,with prolific contributors such as Lai Xinsheng,Liu Zhibin,and Niu Wenmin.It included 449 research institutions,with prominent contributors being the First Affiliated Hospital of Heilongjiang University of Chinese Medicine,Heilongjiang University of Chinese Medicine,and Guangzhou University of Chinese Medicine.Additionally,635 keywords were identified,forming 23 clusters.High-frequency keywords included"cognitive function","rats",and"hippocampus".Conclusion The protection and repair of nerves by acupuncture,the improvement of cognitive function,the comprehensive treatment mode,and the prevention of vascular dementia may be the research hotspots and trends in this field.

Vascular parkinsonism (VaP) is typically defined as having predominant lower body involvement,
postural instability, less prominent rest tremor and little or no response to treatment with levodopa.
In this study, we report a patient with VaP with clear demonstration of a dramatic unilateral decrease
of radiotracer uptake in a 18F-FP-CIT-PET study. A 62-year-old right-handed woman was referred
to the neurology department due to rest tremor and rigidity in the right hand, which began after
undergoing resection surgery for a left acoustic neuroma 7 years prior. Brain MRI, taken at 1 year
after surgery showed an ischemic stroke lesion in the left medial pons and the left substantia nigra.
18F-FP-CIT-PET revealed a marked reduction of radiotracer uptake in left striatum compared to that
of the right. We treated the patient with 100 mg of levodopa, 200 mg of entacarpone and 25 mg of
carbidopa. There was an improvement in bradykinesia and tremor, but the symptoms persisted, and
there was no deterioration during 6 months of observation. After acoustic neuroma surgery, ischemic
complications are uncommon, and even a small lesion in the nigrostriatal pathway can cause a
hemiparkinsonism. If a patient experience sudden onset hemiparkinsonism, they should be carefully
examined for lesions in the nigrostriatal pathways. Under these conditions, the 18F-FP-CIT-PET scan
can enable visualization of a unilateral decrease and is a useful tool for diagnosis and differentiation
from idiopathic Parkinson’s disease
