Several bis(α-aminophosphonates) have been conveniently prepared in good yields using a straightforward multicomponent Kabachnik-Fields reaction between ethane 1,2-diamine or propane 1,3-diamine, diethylphosphite and aldehydes under catalyst-free conditions. The nucleophilic substitution reaction of bis(α-aminophosphonates) prepared and ethyl (2-bromomethyl)acrylate under mild reaction conditions afforded an original synthetic approach to a new series of bis(allylic-α-aminophosphonates).

Age, Sex, and Anatomical Location Patterns in Cutaneous Pyogenic Granuloma Cases.
JAMA Dermatol
January 2025
Division of Dermatology, Departments of Medicine and Pediatrics, Washington University School of Medicine in St Louis, St Louis, Missouri.
Importance: Cutaneous pyogenic granulomas (PGs) are commonly encountered, benign, vascular tumors, in which epidemiologic factors have been variably reported, in part, due to sample size limitations and a focus on either adult or pediatric patients.
Objective: To assemble a large dataset of pathologically diagnosed PGs across the continuum of age and investigate patterns of PGs by demographic factors, including age, sex, and anatomical location.
Design, Setting, And Participants: This retrospective case series included case reports of patients with pathologically confirmed PGs of cutaneous origin reported between April 1, 2010, to March 31, 2020.
The aim of the study is to apply mathematical methods to generate forecasts of the dynamics of random values of the percentage increase in the total number of infected people and the percentage increase in the total number of recovered and deceased patients. The obtained forecasts are used for retrospective forecasting of COVID-19 epidemic process dynamics in St. Petersburg and in Moscow.

Musculoskeletal Ultrasound School, Italian Society for Ultrasound in Medicine and Biology, Bologna, Italy.
Objective: The aim of this work is to demonstrate how the chronicity of low back pain can modify the trophism of the paraspinal muscles, by performing an ultrasound and MRI evaluation of the paraspinal muscles in the lumbar spine and correlating it to the time of onset of low back pain.
Materials And Methods: An ultrasound evaluation was carried out in the lumbar area with a 5-17 MHz linear probe of the paraspinal muscles of the lumbar region, compared with the MRI of the lumbar spine, in patients presented to our attention for chronic low back pain (> 6 months), from January 2021 to January 2023. In each patient, two series of images were analyzed, in the coronal and sagittal planes.
