The Student Attitudes Toward School Safety Measures (SATSSM) instrument was developed as a new tool to assess high school students' attitudes towards school safety promotion methods. A theory-based pool of statements was scaled using Thurstone's equal appearing interval method by 186 student judges to yield a 30-item instrument. The draft version was operationalized into a 5-point, Likert scale format, using a new sample of 182 students. Exploratory factor analysis suggested three factors: mediation, surveillance, and searching methods. The SATSSM was reduced to six items for each scale with a five-item social desirability scale added, and piloted with 66 new students. Final administration of the SATSSM to 166 new students yielded scale and overall internal consistencies exceeding .80 with low interscale correlations. A simultaneously administered questionnaire measuring perceptions of school safety suggested students possessed increased awareness of school violence, but they believed improving school safety is beyond their school's control.

Cerebral Microbleeds and Amyloid Pathology Estimates From the Amyloid Biomarker Study.
JAMA Netw Open
January 2025
Alzheimer Center Limburg, Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University, Maastricht, the Netherlands.
Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).
Boosting the catalytic efficiency of UGT51 for efficient production of rare ginsenoside Rh2.
Folia Microbiol (Praha)
January 2025
Biofuels Institute, School of Emergency Management, School of the Environment and Safety Engineering, Jiangsu University, Zhenjiang, 212013, China.
Ginsenoside Rh2(S) is well-known for its therapeutic potential against diverse conditions, including some cancers, inflammation, and diabetes. The enzymatic activity of uridine diphosphate glycosyltransferase 51 (UGT51) from Saccharomyces cerevisiae plays a pivotal role in the glycosylation process between UDP-glucose (donor) and protopanaxadiol (acceptor), to form ginsenoside Rh2. However, the catalytic efficiency of the UGT51 has remained a challenging task.

Eur J Clin Microbiol Infect Dis
January 2025
University of Sassari, Sassari, Italy.
Introduction: Ceftazidime-avibactam (CAZ-AVI) has emerged as a promising treatment option for Gram-negative infections, particularly those caused by CAZ-Non-Susceptible (NS) pathogens. This systematic review and meta-analysis aim to assess the efficacy and safety of CAZ-AVI in these challenging infections.
Methods: We systematically queried EMBASE, Cochrane CENTRAL, and PubMed/Medline for studies published until September 15, 2024.
Large-bore aspiration thrombectomy for the treatment of pulmonary embolism in octogenarians.
CVIR Endovasc
January 2025
Department of Radiology and Imaging Sciences, Indiana University School of Medicine, 550 University Blvd, Room 0641, Indianapolis, IN, 46202, USA.
Purpose: To evaluate outcomes in patients aged ≥ 80 years following large-bore aspiration thrombectomy (LBAT) for the treatment of pulmonary embolism (PE).
Materials And Methods: All patients ≥ 80 years of age with PE treated via LBAT at a single center were analyzed from September 2019 - August 2024. This included the octogenarian subgroup from a recently published retrospective analysis assessing all PE patients treated with LBAT at our center between September 2019 and January 2023.
N-Glycosylation modulators for targeted manipulation of glycosylation for monoclonal antibodies.
Appl Microbiol Biotechnol
January 2025
School of Interdisciplinary Research, Indian Institute of Technology Delhi, Hauz Khas, New Delhi, 110016, India.
Monoclonal antibodies are extensively used as biotherapeutics for treatment of a variety of diseases. Glycosylation of therapeutic antibodies is considered a critical quality attribute as it influences the effector function, circulatory half-life, immunogenicity, and eventually efficacy and patient safety. During upstream process development, media components play a significant role in determining the glycosylation profile.
