Cancer Incidence in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) - The Onco-SOL Ancillary Study.

Background: Few studies have examined how cancer incidence varies by country of origin among United States Hispanic/Latino adults. Herein, we describe the incidence rates of cancer overall and for screen-detectable, tobacco-related, and obesity-related cancers among 16,415 participants in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), an ongoing population-based cohort study of Hispanic/Latino adults from diverse backgrounds.

Methods: Cohort participant records were linked to the state cancer registries in New York, Florida, California, and Illinois to ascertain cancer incidence from baseline (2008-2011) through 2021.

Sanfetrinem, an oral β-lactam antibiotic repurposed for the treatment of tuberculosis.

Tuberculosis (TB) is historically the world's deadliest infectious disease. New TB drugs that can avoid pre-existing resistance are desperately needed. The β-lactams are the oldest and most widely used class of antibiotics to treat bacterial infections but, for a variety of reasons, they were largely ignored until recently as a potential treatment option for TB.

Noradrenergic suppression to reduce electroencephalographic arousal after intubation: a randomised, placebo-controlled trial.

Background: Intraoperative awareness, without explicit recall, occurs after induction of anaesthesia in approximately 10% of persons under 40 yr of age. Most anaesthetic agents minimally suppress the noradrenergic system. We hypothesised that addition of dexmedetomidine, which suppresses noradrenergic activity, may reduce encephalographic (EEG) arousal in response to tracheal intubation; such an effect would lay the foundation for future studies of dexmedetomidine in reducing intraoperative awareness.

Microextraction-Single Particle-Inductively Coupled Plasma-Mass Spectrometry for the Direct Analysis of Nanoparticles on Surfaces.

A novel employment of single particle-inductively coupled plasma-mass spectrometry (SP-ICP-MS) was developed, where a microextraction (ME) probe is used to sample nanoparticles from a surface and analyze them in a single analytical step. The effects of several parameters on the performance of ME-SP-ICP-MS were investigated, including the flow rate, choice of carrier solution, particle size, and the design of the microextraction probe head itself. The optimized ME-SP-ICP-MS technique was used to compare the extraction efficiency (EE, defined as the ratio of particles measured to particles deposited on the surface) of the commercial probe head to a newly designed SP polyether ether ketone (PEEK) probe head.

Lack of integrated number sense among college students: Evidence from rational number cross-notation comparison.

Growing evidence highlights the predictive power of cross-notation magnitude comparison (e.g., 2/5 vs.
