IMPLICATIONS This study provides new insight into the mechanism of pitavastatin as an anticancer drug and suggests that the combination of pitavastatin with capmatinib is a useful therapeutic strategy in OSCC and ESCC.This article details a risk-based methodology designed to assign environmental classifications to the different operations in biopharmaceutical facilities manufacturing non-sterile (low bioburden) drug substance. Generally, environmental conditions for active pharmaceutical ingredient manufacture are established based on previous experiences or expectations or on extrapolated interpretations of current good manufacturing practices guidelines. Improvements in equipment design and operation, especially the use of closed systems, allow certain process steps to take place in controlled environment areas rather than in classified clean rooms. However, the design of facilities has not developed to reflect these technological advancements. The result is that facility designs are more complex with multiple environmental classifications, resulting in far higher capital and operational costs than necessary given the current technology and understanding. The authors propose a formal risk assessment-based methodology thain relation to a variety of process steps in different operating scenarios, to demonstrate how the assessment is applied. The methodology strongly supports the implementation of closed systems and demonstrates the limited need for classified areas. With fewer classified rooms, companies can reduce the complexity of facility layout and save costs without compromising patient safety or product quality.
Coiling, including balloon-assisted coiling (BAC), is the first-line therapy for ruptured and unruptured aneurysms. Its efficacy can be clinically evaluated by bleeding/rebleeding rate after coiling, and anatomically evaluated by aneurysm occlusion post-procedure and during follow-up. We aimed to analyze immediate post-coiling aneurysm occlusion and associated factors within the Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) population.

Between December 2013 and May 2015, 16 neurointerventional departments prospectively enrolled participants treated for ruptured and unruptured aneurysms (ClinicalTrials.gov NCT01942512). Participant demographics, aneurysm characteristics, and endovascular techniques were recorded. In patients with aneurysms treated by coiling or BAC, immediate post-operative aneurysm occlusion was independently evaluated by a core lab using a 3-grade scale complete occlusion, neck remnant, and aneurysm remnant.

Of 1135 participants (age 53.8±12.8 years, 754 women (66.4%)), 1189 aneurysms were analyzed. Treatment modality was standard coiling in 645/1189 aneurysms (54.2%) and BAC in 544/1189 (45.8%). Immediate post-operative aneurysm occlusion was complete occlusion in 57.8%, neck remnant in 34.4%, and aneurysm remnant in 7.8%. Adequate occlusion (complete occlusion or neck remnant) was significantly more frequent in aneurysms with size <10 mm (93.1% vs 86.3%; OR 1.8, 95% CI 1.1 to 3.2; p=0.02) and in aneurysms with a narrow neck (95.8% vs 89.6%; OR 2.5, 95% CI 1.5 to 4.1; p=0.0004). Patients aged <70 years had significantly more adequate occlusion (92.7% vs 87.2%; OR 1.9, 95% CI 1.1 to 3.4; p=0.04).

Immediately after aneurysm coiling, including BAC, adequate aneurysm occlusion was obtained in 92.2%. Age <70 years, aneurysm size <10 mm, and narrow neck were factors associated with adequate occlusion.

To assess the frequency of biologically defined Alzheimer disease (AD) in relation to age, sex,
ε4, and clinical diagnosis in a prospective cohort study evaluated with amyloid-PET and tau-PET.

We assessed cognitively unimpaired (CU) elderly (n = 166), patients with amnestic mild cognitive impairment (n = 77), and patients with probable AD dementia (n = 62) who underwent evaluation by dementia specialists and neuropsychologists in addition to amyloid-PET with [
F]AZD4694 and tau-PET with [
F]MK6240. Individuals were grouped according to their AD biomarker profile. Positive predictive value for biologically defined AD was assessed in relation to clinical diagnosis. Frequency of AD biomarker profiles was assessed using logistic regressions with odds ratios (ORs) and 95% confidence intervals (CIs).

The clinical diagnosis of probable AD dementia demonstrated good agreement with biologically defined AD (positive predictive value 85.2%). STAT inhibitor A total of 7.88% of CU were positive for both amyloid-PET and tau-PEin 85.2% of people with clinically defined AD and 7.88% of CU elderly.
Although studies continue to demonstrate lower complications in neurointerventions using transradial access (TRA) compared with transfemoral approaches, anatomic radial variants can be difficult to navigate and remain one of the frequent causes of access site conversion.

To evaluate predictors of TRA failure in neuroendovascular patients with radial loops and suggest a protocol for managing these anomalies.

A prospective collection of patients undergoing TRA at participating institutions from July 2018 to September 2020 was reviewed. Patients with a radial loop were identified. Patient demographics and procedural characteristics were evaluated to determine predictors of both TRA failure and successful reduction of the radial loop.

We identified 32 transradial neurointerventions in which patients had radial loops. Twenty-two (68.8%) were identified by diagnostic angiography, and the majority were performed for evaluation or treatment of an aneurysm (56.3%). TRA failure occurred in 13 (40.6%) of the cohort and happened more frequently in patients over 60 years of age (p=0.01) and those with recurrent radial artery diameters ≤2 mm (p=0.02). Of the 19 patients who had successful TRA, 12 (63.2%) procedures were performed through the recurrent radial artery.

Although radial loops are associated with high transradial failure rates, our results suggest that the presence of a loop is not an absolute contraindication to TRA. Therefore, we recommend attempting loop navigation using our protocol. Patient age, vascular tortuosity, and recurrent radial artery size should help dictate when to convert to an alternative access site.
