Simple and rapid flow cytometry assay for the detection of malignant epithelial cells in body fluids.

Introduction: Morphology is routinely used for detecting malignant cells in body fluids, but it has limitations. Recently, flow cytometry (FCM) is used as an effective tool for studying non-haematological malignancies. The main objective of this study is to standardize a simple and rapid FCM test for the detection of malignant epithelial cells in body fluids.

"Being Queer, It Was Really Isolating": Stigma and Mental Health Among Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ+) Young People During COVID-19.

Lesbian, Gay, Bisexual, Transgender, Queer, and other sexual and gender minority (LGBTQ+) youth and young adults (YYAs) have poorer mental health outcomes than their cisgender, heterosexual peers in large part due to multilevel stigmatization and minority stress. This was exacerbated by psychological stressors stemming from the COVID-19 pandemic; these experiences intersected with YYA unique developmental stage. Here we explored LGBTQ+ YYA's pandemic-related experiences, focusing on intersections between stigma and belonging, developmental processes, and their relationship to mental health.

Evaluation of the protection of sunscreen products against long wavelength ultraviolet A1 and visible light-induced biological effects.

Background: Long wavelength ultraviolet-A1 in combination with visible light induces hyperpigmentation, particularly in dark-skin phototypes. This study evaluated the efficacy of four sunscreen formulations in protecting against VL + UVA1 (370-700 nm).

Methods: The test products (A-D) were applied to the back of 12 volunteers, then irradiated with 320 J/cm VL + UVA1 (3.

COVID-19 testing and vaccination uptake among youth and young adults: Disparities by age, race/ethnicity, sexual orientation, and gender identity.

Background: The COVID-19 pandemic disproportionately impacts youth and young adults (YYA) and YYA with multiple marginalized identities, yet little is known about differences in uptake, testing access, and vaccine concerns among YYA by diverse demographic identities.

Methods: Between 2/2021 and 2/2022, we conducted a national, cross-sectional online survey focused on diverse YYA ages 14 to 24 (n = 983). We explored the prevalence of COVID-19 testing and vaccination among YYA by age, race/ethnicity, and sexual and gender identities.

Efficacy and Risk Stratification of Janus Kinase Inhibitors in the Treatment of Moderate-to-Severe Atopic Dermatitis.

Recently, 3 oral Janus kinase (JAK) inhibitors-abrocitinib, baricitinib, and upadacitinib-were approved in many regions around the world for the treatment of moderate-severe atopic dermatitis (AD). These JAK inhibitors generally have rapid onset of action and short half-life. Higher doses of abrocitinib and upadactinib even demonstrated superior efficacy to dupilumab.

U.S. Breastfeeding Outcomes at the Intersection: Differences in Duration Among Racial and Ethnic Groups With Varying Educational Attainment in a Nationally Representative Sample.

Background: As breastfeeding rates in the United States increase, barriers persist for Black, Latine, and low-socioeconomic status household dyads when compared to White and high-socioeconomic status household dyads. Previous breastfeeding disparities research has almost exclusively considered the influence of race, ethnicity, and socioeconomic status separately, although these attributes are not randomly distributed across the population.

Research Aim: To identify breastfeeding duration patterns by race/ethnicity and educational attainment in a nationally representative U.

Which Clinical Measurement Tools for Atopic Dermatitis Severity Make the Most Sense in Clinical Practice?

Assessment of atopic dermatitis (AD) severity is essential for therapeutic decision making and monitoring treatment progress. However, there are a myriad of clinical measurement tools available, some of which are impractical for routine clinical use despite being recommended for clinical trials in AD. For measurement tools to be used in clinical practice, they should be valid, reliable, rapidly completed, and scored, and easily incorporated into existing clinic workflows.

Safety of Oral Janus Kinase Inhibitors in the Treatment of Moderate-to-Severe Atopic Dermatitis.

Multiple Janus Kinase (JAK) inhibitors were developed as potential treatments for moderate-to-severe atopic dermatitis (AD). There is a substantial amount of safety data from recent trials of oral JAK inhibitors in patients with AD. However, the vast majority of safety data for oral JAK inhibitors is derived from patients with rheumatoid arthritis and other immune-mediated disorders, and is primarily derived from tofacitinib, a pan-selective JAK inhibitor.

Racial disparities in dermatology.

Significant racial/ethnic disparities in dermatologic care and their subsequent impact on dermatologic conditions were recently reported. Contributing factors include socioeconomic factors, gaps in educational exposure, and underrepresentation of minority groups in the dermatologic workforce. In 2021, the American Academy of Dermatology (AAD) announced its three-year plan to expand diversity, equity, and inclusion in dermatology.

Role of ERK signaling in bladder urothelium in response to cyclophosphamide injury.

Mice with inducible urothelial deletion of fibroblast growth factor receptor 2 (ShhCreERT2;Fgfr2 ) injured with cyclophosphamide had aberrant basal cell endoreplication and poor regeneration. The endoreplication correlated with an absence of phosphorylated (activated) ERK expression in urothelium. We assessed whether inhibiting ERK activity phenocopied the urothelial defects in injured Fgfr2 mutant mice.

Role of high acquisition flow cytometry in the detection of marrow involvement in patients with extramedullary B cell non-Hodgkins lymphoma: a comparison with marrow aspirate cytology, trephine biopsy, and PET.

Detection of marrow infiltration is crucial in extramedullary B cell non-Hodgkin lymphoma (B-NHL). We studied the efficiency of high acquisition flow cytometry (FCM) in detecting marrow involvement in B-NHL patients and compared its performance with marrow aspiration (BMA) cytology, marrow biopsy (BMB), and positron emission tomography (PET). No case with marrow infiltration was found to be BMB positive and FCM negative.

Durability of and role of AKT in FGF7p urothelial protection against cyclophosphamide.

We previously identified a peptide derived from human fibroblast growth factor 7 (FGF7p) that blocks urothelial apoptosis similar to full-length FGF7, although effects of FGF7p on urothelial repair are unknown. Also, while urothelial AKT activation downstream of FGF7p correlated with the anti-apoptotic effects, we have not directly interrogated the role of AKT in mediating the cytoprotection. Our goal was to assess effects of FGF7p on urothelial repair and the role of AKT signaling in mediating the cytoprotective effects of FGF7p.

Systematic review of photodynamic therapy for the treatment of hidradenitis suppurativa.

Objective: To perform a systematic review of available literature regarding the use of 5-aminolevulinic acid (ALA) and ALA derivative photodynamic therapy (PDT) in the treatment of hidradenitis suppurativa (HS) and provide recommendations on its use.

Methods: A systematic review was performed of all published studies up to September 1, 2019 from nine databases, including PubMed, that evaluated PDT in the treatment of HS. For each study, quality of evidence and risk of bias was evaluated.

Safety and Efficacy of Intense Pulsed Light With Radiofrequency in United States Hidradenitis Suppurativa Patients.

Unlabelled: Copy: The combination of intense pulsed light and radiofrequency has been described in German populations to be a noninvasive therapy option for patients with hidradenitis suppurativa, demonstrating significant improvements in the quality of life and reduction in number of inflammatory lesions.

Objective: To evaluate the efficacy and safety of combination intense pulsed light and radiofrequency therapy in patients with hidradenitis suppurativa in the United States.

Methods: A prospective split body was conducted in the United States on patients with bilateral hidradenitis suppurativa.

FGF7 peptide (FGF7p) mimetic mitigates bladder urothelial injury from cyclophosphamide.

Although full-length fibroblast growth factor 7 (FGF7) blocks cyclophosphamide-induced urothelial apoptosis in mice, limitations include high production costs because of its large size. We previously identified a small peptide derived from FGF2 that mitigated acute radiation syndrome as well as full-length FGF2. Based on the sequence of the FGF2 peptide, we synthesized a corresponding 19 amino acid FGF7 peptide (FGF7p).

The suitability of treating atopic dermatitis with Janus kinase inhibitors.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease with significant morbidity and reduced quality of life, especially in patients with moderate-severe AD. Recently, topical and oral Janus kinase (JAK)-inhibitors were investigated as treatments for mild-moderate and moderate-severe AD. However, rare serious adverse-events observed with JAK-inhibitor therapy in AD, rheumatoid arthritis, and other immune-mediated disorders warrant careful consideration.

AKT Signaling Downstream of KGF Is Necessary and Sufficient for Blocking Cyclophosphamide Bladder Injury.

Keratinocyte growth factor (KGF) drives phosphorylated (activated) AKT (pAKT) in bladder urothelium, which correlates with cytoprotection from cyclophosphamide. The current study determined whether: i) KGF modifies AKT targets [B-cell lymphoma protein 2-associated agonist of cell death (BAD) and mammalian target of rapamycin complex (mTORC)-1] that could block apoptosis; ii) AKT signaling is required for KGF cytoprotection; iii) direct AKT activation drives cytoprotection; iv) co-administration of KGF and an AKT inhibitor blocks urothelial cytoprotection and AKT and AKT-target activation; and v) an AKT agonist prevents cyclophosphamide-induced urothelial apoptosis. Mice were given KGF and cyclophosphamide (or sham injury), and pBAD (readout of BAD inhibition) or p-p70S6k (pS6, readout of mTORC1 signaling) was assessed.

Dermatology for the internist: optimal diagnosis and management of atopic dermatitis.

Internists are front-line health care providers that commonly provide the first encounter to patients for dermatological conditions, especially atopic dermatitis (AD). Internists need to be comfortable with managing mild-moderate AD in their practices. Criteria and guidelines established in dermatology literature are available to help the general practitioner diagnose and treat AD.

Urothelial progenitors in development and repair.

Urothelium is a specialized multilayer epithelium that lines the urinary tract from the proximal urethra to the kidney. In addition to proliferation and differentiation during development, urothelial injury postnatally triggers a robust regenerative capacity to restore the protective barrier between the urine and tissue. Mounting evidence supports the existence of dedicated progenitor cell populations that give rise to urothelium during development and in response to injury.

The value of photomedicine in a global health crisis: Utilizing ultraviolet C to decontaminate N95 respirators during the COVID-19 pandemic.

One early problem during the height of the COVID-19 global pandemic, caused by severe acute respiratory syndrome 2 (SARS-CoV-2), was the shortage of personal protective equipment donned by healthcare workers, particularly N95 respirators. Given the known virucidal, bactericidal, and fungicidal properties of ultraviolet irradiation, in particular ultraviolet C (UVC) radiation, our photomedicine and photobiology unit explored the role of ultraviolet germicidal irradiation (UVGI) using UVC in effectively decontaminating N95 respirators. The review highlights the important role of photobiology and photomedicine in this pandemic.

Assessment of inter-rater reliability of clinical hidradenitis suppurativa outcome measures using ultrasonography.

Background: Hidradenitis suppurativa (HS) staging and severity is typically based upon physical examination findings, which can result in misclassification of severity based on subclinical disease activity and significant variation between healthcare providers. Ultrasonography (US) is an objective tool to help evaluate subclinical disease and to more accurately classify disease severity.

Aim: To evaluate inter-rater reliability in HS disease severity assessment using clinical and US techniques.
