Xylazine-Induced Necrotic Skin Ulcers in a Fentanyl-Injecting Individual in South Florida, United States: A Case Report.

Xylazine, commonly referred to as "Tranq," is an alpha-2-adrenergic receptor agonist that is FDA-approved only as a sedative and tranquilizer for veterinary use. However, its use as an adulterant in various illicit drugs, including fentanyl, has been on the rise, leading to its street name, "Tranq-Dope." Intravenous injection use of xylazine produces distinctive skin ulceration with accompanying necrosis, which can be considered virtually pathognomonic.

While CRC is a well-described disease, the relationship between its development and features of the intestinal microbiome is still being understood. Evidence linking enrichment in colorectal tumor tissue has prompted the elucidation of various molecular mechanisms and tumor-promoting attributes.

I can't get no satisfaction: Burnout, stress, and depression in Latin medical students.

The state of emotional, physical, and mental exhaustion caused by excessive and prolonged stress, known as Burnout Syndrome (BS), is not only affecting the medical workforce but medical students in training. Gender, race, ethnicity, and potentially other variables can serve as significant risk factors contributing to BS among medical students. Despite the importance of understanding these disparities, very few studies in the U.

Editorial Commentary: Decreased Hip Ligament Thickness in Patients With Dysplasia May Contribute to Hip Instability, Above and Beyond Associated Acetabular Under-coverage.

Hip dysplasia is a pathomorphologic deformity that leads to decreased acetabular coverage and hip instability. Many different radiographic measurements have been explored to characterize hip dysplasia, including the lateral center-edge angle, femoral-epiphyseal acetabular roof index, and Tönnis angle. Magnetic resonance imaging offers 3-dimensional characterization of the hip pathomorphology that may be more detailed than 2-dimensional radiographs, as well as a modality that is free of radiation.

[Liver transplantation as treatment for acetaminophen poisoning].

Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause fulminant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries.

Effect of an aperture in atomic gravimetry.

There is a continuous interest in shrinking the dimensions of portable atomic gravimeters. This inevitably ends up truncating the Gaussian wings of the excitation laser beams whose effect has not been properly quantified yet. The diffraction pattern created from this aperture creates ripples in the wavefront in both the phase and the intensity.

One-step synthesis of amphiphilic copolymers PDMS--PEG using tris(pentafluorophenyl)borane and subsequent study of encapsulation and release of curcumin.
