Examining the Relationship of Cannabis use Patterns, Mental Health, and Sociodemographic Factors: A Focus on Cannabis Vaping, Smoking and Dual-Use.

Background: Cannabis vaping, and co-use with cannabis smoking, can exacerbate the risks of developing respiratory diseases and cannabis dependence. This study aims to examine the mental health profiles and sociodemographic correlates of adults who vape cannabis and engage in dual cannabis use (vaping/ smoking), compared to those who smoke cannabis.

Methods: The most recent, cross-sectional wave of the Population Assessment of Tobacco and Health Study (Wave 6) was used in this study.

Epidemiology of dog bite and strike related hospital admissions in Scotland, 1997 to 2022.

Objectives: To describe the epidemiology of dog-related injuries leading to hospital admission in Scotland and to estimate the direct health care costs.

Study Design: A retrospective, longitudinal analysis of Scottish hospital admissions coded under the W54 ICD-10 code 'bitten or struck by dog', 1997-2022.

Methods: Hospital admissions episodes coded under W54 were extracted from the SMR1/01 dataset.

Label-free nanoscopy of cell metabolism by ultrasensitive reweighted visible stimulated Raman scattering.

Super-resolution imaging of cell metabolism is hindered by the incompatibility of small metabolites with fluorescent dyes and the limited resolution of imaging mass spectrometry. We present ultrasensitive reweighted visible stimulated Raman scattering (URV-SRS), a label-free vibrational imaging technique for multiplexed nanoscopy of intracellular metabolites. We developed a visible SRS microscope with extensive pulse chirping to improve the detection limit to ~4,000 molecules and introduced a self-supervised multi-agent denoiser to suppress non-independent noise in SRS by over 7.

Responsiveness to transcutaneous spinal stimulation for upper extremity recovery following spinal cord injury: A case series exploration of midsagittal tissue bridges.

Context: Transcutaneous spinal stimulation (TSS), applied to the cervical spine, is able to improve voluntary upper extremity strength and function in individuals with cervical spinal cord injury (SCI). While most respond and improve in the presence of TSS, others do not respond as favorably. Midsagittal tissue bridges, adjacent to the lesion, can be observed and measured using T-weighted magnetic resonance imaging (MRI), and both ventral and dorsal tissue bridges are associated with recovery following SCI.
