Background: Solid organ transplant recipients (OTR) are at an increased risk of developing squamous cell carcinoma (SCC) of the skin after transplantation. In predominantly white cohorts, Fitzpatrick skin type (FST) has been reported to be a risk factor for developing posttransplantation skin cancers.
Objective: Our goal was to determine if FST is a statistically significant risk factor for the development of SCC after solid organ transplantation in a diverse US population of OTR.
Methods: A cohort of OTR completed a questionnaire of demographic factors, transplant type, FST, and skin cancer history. Univariate and multivariate analyses were performed to determine the risk factors for development of SCC after transplantation.
Results: As expected, male subjects had an increased risk for SCC compared with female subjects (P = .02), and those aged 50 years and older at the time of transplantation were more likely to develop SCC compared with those younger than 50 years (P < .001). The risk of SCC increased with each incremental decrease in FST, from FST VI to FST I (linear test for trend P < .001).
Limitations: Our questionnaire did not ask specifically about immunosuppressive medications; instead, organ transplant category was used as a proxy for level of immunosuppression.
Conclusions: FST, a patient-reported variable, is an independent risk factor for the development of SCC in OTR, and should be elicited from patients who have gone or will undergo organ transplantation.

Background: Langerhans cell histiocytosis (LCH) is a rare disease, most prevalent in children. Ultrasound is a noninvasive, cheap, and widely available technique. However, systematic elucidation of sonographic features of LCH and treatment related follow-up are relatively few, resulting in overall underestimation of the clinical value of ultrasound in diagnosing and monitoring LCH.

Frostbite injury refers to cold tissue injury which typically affects the peripheral areas of the body, and is associated with limb loss and high rates of morbidity. Historically, treatment options have been limited to supportive care, leading to suboptimal outcomes for affected patients. The pathophysiology of frostbite injury has been understood in recent years to share similarity with that of cold ischemia-reperfusion injury as seen in solid organ transplantation, of which mitochondria play an important contributing role.

Biomacromolecules partition into numerous types of biological condensates or membrane-less organelles via liquid-liquid phase separation (LLPS). Newly formed liquid-like condensates may further undergo phase transition to convert into other material states, such as gel or solid states. Different biological condensates possess distinct material properties to fulfil their physiological functions in diverse cellular pathways and processes.

There is substantial variation in access to transplantation across the United States that is not entirely explained by the availability of donor organs. Barriers to transplantation and variation in care among patients with end-stage organ disease exist prior to patients' placement on a transplant waiting list as well as following waitlist placement. However, there are currently no national data available to examine rates and variations in key care processes related to pre-listing, including transplant referral, evaluation, or candidate selection.

Cryptococcal disease is the third most common invasive fungal infection in solid organ transplant recipients and is associated with high-morbidity and -mortality rates. Donor-derived Cryptococcus spp. infection typically manifests within the first month post-procedure and has historically been caused by C.
