ABSTRACT

OBJECTIVES: Epidermal growth factor receptor (EGFR) inhibition with cetuximab is a standard treatment for head and neck squamous cell carcinoma (HNSCC). Activation of the receptor tyrosine kinases AXL, MET and VEGFR can mediate resistance to cetuximab. Cabozantinib, a multikinase inhibitor (MKI) targeting AXL/MET/VEGFR, has demonstrated antitumor activity in preclinical models of HNSCC. This investigator- initiated phase I trial evaluated the safety and efficacy of cetuximab plus cabozantinib in patients with recurrent/metastatic (R/M) HNSCC. MATERIALS AND METHODS: Patients received cetuximab concurrently with cabozantinib daily on a 28-day cycle. Using a 3 + 3 dose-escalation design, the primary endpoint was to determine the maximally tolerated dose (MTD) of cabozantinib. Secondary endpoints included overall response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) RESULTS: Among the 20 patients enrolled, most had prior disease progression on immune checkpoint inhibitors (95 %), platinum-based chemotherapy (95 %), and cetuximab (80 %). No dose-limiting toxicities were recorded and the MTD for cabozantinib was established to be 60 mg. Grade ≥ 3 adverse events occurred in 65 % of patients (n = 13). ORR was 20 %, with 4 partial responses (PRs). Two PRs were observed in cetuximab-naïve patients (n = 4), with an ORR of 50 % in this subgroup. In the overall population, DCR was 75 %, median PFS was 3.4 months and median OS was 8.1 months. CONCLUSION: Cetuximab plus cabozantinib demonstrated a manageable toxicity profile and preliminary efficacy in patients with heavily treated R/M HNSCC. The combination of cetuximab with MKIs targeting the AXL/MET/VEGFR axis warrants further investigation, including in cetuximab-naïve patients.

ABSTRACT

Malassezia are yeast species that commonly colonize healthy skin. However, they have been associated with or implicated in the pathogenesis of numerous skin disorders, particularly in the setting of pediatric populations. In this review, we will focus on several Malassezia-associated skin conditions manifesting in infants, children, and adolescents: pityriasis versicolor, Malassezia folliculitis, infantile and adolescent seborrheic dermatitis, head and neck dermatitis, and neonatal cephalic pustulosis. We examine the literature and provide an overview of these conditions, including clinical presentation in diverse skin colors, diagnosis, risk factors, and treatment and management. Additionally, we summarize and highlight some of the proposed theories on the role of Malassezia spp. in the pathogenesis of these skin conditions.

ABSTRACT

Teclistamab, an off-the-shelf B-cell maturation antigen (BCMA) × CD3 bispecific antibody that mediates T-cell activation and subsequent lysis of BCMA-expressing myeloma cells, is approved for the treatment of patients with relapsed/refractory multiple myeloma (RRMM). As a T-cell redirection therapy, clinical outcomes with teclistamab may be influenced by patient immune fitness and tumor antigen expression. We correlated tumor characteristics and baseline immune profiles with clinical response and disease burden in patients with RRMM from the pivotal phase 1/2 MajesTEC-1 study, focusing on patients treated with 1.5 mg/kg of teclistamab (N = 165). Peripheral blood samples were collected at screening and bone marrow samples were collected at screening and cycle 3. Better clinical outcomes to teclistamab correlated with higher baseline total T-cell counts in the periphery. In addition, responders (partial response or better) had a lower proportion of immunosuppressive regulatory T cells, T cells expressing co-inhibitory receptors (CD38, PD-1, PD-1/TIM-3), and soluble BCMA, and a T-cell profile suggestive of a more cytolytic potential, compared with nonresponders. Neither frequency of baseline bone marrow BCMA expression nor BCMA receptor density were associated with clinical response to teclistamab. Improved progression-free survival was observed in patients with a lower frequency of T cells expressing exhaustion markers and immunosuppressive regulatory T cells. Overall, response to teclistamab was associated with baseline immune fitness; nonresponders had immune profiles suggestive of immune suppression and T-cell dysfunction. These findings illustrate the importance of the contribution of the immune landscape to T-cell redirection therapy response. This trial was registered at www.ClinicalTrials.gov, NCT03145181/NCT04557098.

ABSTRACT

Importance: Chronic skin disorders in children frequently are visible and can cause stigmatization. However, the extent of stigmatization from chronic skin disease and association with mental health needs further study. Objective: To examine the extent of stigma, dependence on disease visibility and severity, and association with mental health and quality of life (QOL) in chronic pediatric skin disease. Design, Setting, and Participants: A cross-sectional, single-visit study was conducted at 32 pediatric dermatology centers in the US and Canada from November 14, 2018, to November 17, 2021. Participants included patients aged 8 to 17 years with chronic skin disease and 1 parent. Main Outcomes and Measures: Using the Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) Stigma-Skin, the extent of stigma with child-, caregiver-, and physician-assessed disease visibility (primary outcome) and severity was compared, as well as reduced QOL (assessed by Skindex-Teen), depression, anxiety, and poor peer relationships (PROMIS child and proxy tools) (secondary outcomes). Results: The study included 1671 children (57.9% female; mean [SD] age, 13.7 [2.7] years). A total of 56.4% participants had self-reported high disease visibility and 50.5% had moderate disease severity. Stigma scores significantly differed by level of physician-assessed and child/proxy-assessed disease visibility and severity. Among children with chronic skin disorders, predominantly acne, atopic dermatitis, alopecia areata, and vitiligo, only 27.0% had T scores less than 40 (minimal or no stigma) and 43.8% had at least moderate stigma (T score ≥45) compared with children with a range of chronic diseases. Stigma scores correlated strongly with reduced QOL (Spearman ρ = 0.73), depression (ρ = 0.61), anxiety (ρ = 0.54), and poor peer relationships (ρ = -0.49). Overall, 29.4% of parents were aware of bullying of their child, which was strongly associated with stigma (Cohen d = -0.79, with children who were not bullied experiencing lower levels of stigma). Girls reported more stigma than boys (Cohen d = 0.26). Children with hyperhidrosis and hidradenitis suppurativa were most likely to have increased depression and anxiety. Conclusions and Relevance: The findings of this study suggest that physician assessment of disease severity and visibility is insufficient to evaluate the disease impact in the patient/caregiver. Identifying stigmatization, including bullying, and tracking improvement through medical and psychosocial interventions may be a key role for practitioners.

ABSTRACT

Importance: The effects of breast cancer incidence changes and advances in screening and treatment on outcomes of different screening strategies are not well known. Objective: To estimate outcomes of various mammography screening strategies. Design, Setting, and Population: Comparison of outcomes using 6 Cancer Intervention and Surveillance Modeling Network (CISNET) models and national data on breast cancer incidence, mammography performance, treatment effects, and other-cause mortality in US women without previous cancer diagnoses. Exposures: Thirty-six screening strategies with varying start ages (40, 45, 50 years) and stop ages (74, 79 years) with digital mammography or digital breast tomosynthesis (DBT) annually, biennially, or a combination of intervals. Strategies were evaluated for all women and for Black women, assuming 100% screening adherence and "real-world" treatment. Main Outcomes and Measures: Estimated lifetime benefits (breast cancer deaths averted, percent reduction in breast cancer mortality, life-years gained), harms (false-positive recalls, benign biopsies, overdiagnosis), and number of mammograms per 1000 women. Results: Biennial screening with DBT starting at age 40, 45, or 50 years until age 74 years averted a median of 8.2, 7.5, or 6.7 breast cancer deaths per 1000 women screened, respectively, vs no screening. Biennial DBT screening at age 40 to 74 years (vs no screening) was associated with a 30.0% breast cancer mortality reduction, 1376 false-positive recalls, and 14 overdiagnosed cases per 1000 women screened. Digital mammography screening benefits were similar to those for DBT but had more false-positive recalls. Annual screening increased benefits but resulted in more false-positive recalls and overdiagnosed cases. Benefit-to-harm ratios of continuing screening until age 79 years were similar or superior to stopping at age 74. In all strategies, women with higher-than-average breast cancer risk, higher breast density, and lower comorbidity level experienced greater screening benefits than other groups. Annual screening of Black women from age 40 to 49 years with biennial screening thereafter reduced breast cancer mortality disparities while maintaining similar benefit-to-harm trade-offs as for all women. Conclusions: This modeling analysis suggests that biennial mammography screening starting at age 40 years reduces breast cancer mortality and increases life-years gained per mammogram. More intensive screening for women with greater risk of breast cancer diagnosis or death can maintain similar benefit-to-harm trade-offs and reduce mortality disparities.

ABSTRACT

BACKGROUND: Racial and ethnic disparities in life expectancy in the United States have been widely documented. To date, there remains a paucity of similar data in patients with inborn errors of immunity (IEIs). OBJECTIVE: Our aim was to examine racial and ethnic differences in mortality due to an IEI in the United States. METHODS: We analyzed National Center for Health Statistics national mortality data from 2003 to 2018. We quantified age-adjusted death rate and age-specific death rate as a result of an IEI for each major racial and ethnic group in the United States and examined the association of race and ethnicity with death at a younger age. RESULTS: From 2003 to 2018, IEIs were reported as the underlying or contributing cause of death in 14,970 individuals nationwide. The age-adjusted death rate was highest among Black patients (4.25 per 1,000,000 person years), compared with 2.01, 1.71, 1.50, and 0.92 per 1,000,000 person years for White, American Indian/Alaska Native, Hispanic, and Asian/Pacific Islander patients, respectively. The odds of death before age 65 years were greatest among Black patients (odds ratio [OR] = 5.15 [95% CI = 4.61-5.76]), followed by American Indian/Alaska Native patients (OR = 3.58 [95% CI = 2.30-5.82]), compared with White patients. The odds of death before age 24 years were greater among Hispanic patients than among non-Hispanic patients (OR = 3.60 [95% CI = 3.08-4.18]). CONCLUSION: Our study highlights racial and ethnic disparities in mortality due to an IEI and the urgent need to further identify and systematically remove barriers in care for historically marginalized patients with IEIs.

ABSTRACT

BACKGROUND: Guidelines recommend shared decision-making (SDM) around mammography screening for women ≥ 75 years old. OBJECTIVE: To use microsimulation modeling to estimate the lifetime benefits and harms of screening women aged 75, 80, and 85 years based on their individual risk factors (family history, breast density, prior biopsy) and comorbidity level to support SDM in clinical practice. DESIGN, SETTING, AND PARTICIPANTS: We adapted two established Cancer Intervention and Surveillance Modeling Network (CISNET) models to evaluate the remaining lifetime benefits and harms of screening U.S. women born in 1940, at decision ages 75, 80, and 85 years considering their individual risk factors and comorbidity levels. Results were summarized for average- and higher-risk women (defined as having breast cancer family history, heterogeneously dense breasts, and no prior biopsy, 5% of the population). MAIN OUTCOMES AND MEASURES: Remaining lifetime breast cancers detected, deaths (breast cancer/other causes), false positives, and overdiagnoses for average- and higher-risk women by age and comorbidity level for screening (one or five screens) vs. no screening per 1000 women. RESULTS: Compared to stopping, one additional screen at 75 years old resulted in six and eight more breast cancers detected (10% overdiagnoses), one and two fewer breast cancer deaths, and 52 and 59 false positives per 1000 average- and higher-risk women without comorbidities, respectively. Five additional screens over 10 years led to 23 and 31 additional breast cancer cases (29-31% overdiagnoses), four and 15 breast cancer deaths avoided, and 238 and 268 false positives per 1000 average- and higher-risk screened women without comorbidities, respectively. Screening women at older ages (80 and 85 years old) and high comorbidity levels led to fewer breast cancer deaths and a higher percentage of overdiagnoses. CONCLUSIONS: Simulation models show that continuing screening in women ≥ 75 years old results in fewer breast cancer deaths but more false positive tests and overdiagnoses. Together, clinicians and 75 + women may use model output to weigh the benefits and harms of continued screening.

ABSTRACT

BACKGROUND: Populations of African American or Black women have persistently higher breast cancer mortality than the overall US population, despite having slightly lower age-adjusted incidence. METHODS: Three Cancer Intervention and Surveillance Modeling Network simulation teams modeled cancer mortality disparities between Black female populations and the overall US population. Model inputs used racial group-specific data from clinical trials, national registries, nationally representative surveys, and observational studies. Analyses began with cancer mortality in the overall population and sequentially replaced parameters for Black populations to quantify the percentage of modeled breast cancer morality disparities attributable to differences in demographics, incidence, access to screening and treatment, and variation in tumor biology and response to therapy. RESULTS: Results were similar across the 3 models. In 2019, racial differences in incidence and competing mortality accounted for a net ‒1% of mortality disparities, while tumor subtype and stage distributions accounted for a mean of 20% (range across models = 13%-24%), and screening accounted for a mean of 3% (range = 3%-4%) of the modeled mortality disparities. Treatment parameters accounted for the majority of modeled mortality disparities: mean = 17% (range = 16%-19%) for treatment initiation and mean = 61% (range = 57%-63%) for real-world effectiveness. CONCLUSION: Our model results suggest that changes in policies that target improvements in treatment access could increase breast cancer equity. The findings also highlight that efforts must extend beyond policies targeting equity in treatment initiation to include high-quality treatment completion. This research will facilitate future modeling to test the effects of different specific policy changes on mortality disparities.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted human-to-human via aerosols and air-borne droplets. Therefore, capturing and destroying viruses from indoor premises are essential to reduce the probability of human exposure and virus transmission. While the heating, ventilation, and air conditioning (HVAC) systems help in reducing the indoor viral load, a targeted approach is required to effectively remove SARS-CoV-2 from indoor air to address human exposure concerns. The present study demonstrates efficient trapping and destruction of SARS-CoV-2 via nano-enabled filter technology using the UV-A-stimulated photoelectrochemical oxidation (PECO) process. Aerosols containing SARS-CoV-2 were generated by nebulization inside an air-controlled test chamber where an air purifier (Air Mini+) was placed. The study demonstrated the efficient removal of SARS-CoV-2 (99.98 %) from the test chamber in less than two minutes and PECO-assisted destruction (over 99%) on the filtration media in 1 h. Furthermore, in a real-world scenario, the Molekule Air-Pro air purifier removed SARS-CoV-2 (a negative RT-qPCR result post-running the filter device) from the circulating air in a COVID-19 testing facility. Overall, the ability of two FDA-approved class II medical devices, Molekule Air-Mini+ and Air-Pro air purifiers, to remove and destroy SARS-CoV-2 in indoor settings was successfully demonstrated. The study indicates that as the "tripledemic" of COVID-19, influenza, and respiratory syncytial virus (RSV) overwhelm the healthcare facilities in the USA, the use of a portable air filtration device will help contain the spread of the viruses in close door facilities, such as in schools and daycare facilities.

ABSTRACT

Neonatal lupus erythematosus (NLE) is an uncommon disorder affecting approximately one out of 20 000 live births in the United States. Common manifestations of NLE include cutaneous eruptions and cardiac involvement. The typical rash of NLE most closely resembles the rash of subacute cutaneous lupus erythematosus both clinically and histopathologically. We present a case of reactive granulomatous dermatitis (RGD) associated with NLE in a 3-month-old male in whom the initial histopathology and immunohistochemistry were concerning for hematologic malignancy. RGD is a unifying term used to describe cutaneous granulomatous eruptions that occur in response to a variety of stimuli, including autoimmune connective tissue diseases. Our case demonstrates the range of histopathological findings that may be present in the setting of NLE.

ABSTRACT

BACKGROUND/OBJECTIVES: The emergency department (ED) is a common point of care for many pediatric hidradenitis suppurativa (HS) patients; however, ED care may not align with recommended treatment standards. The objective of this study is to describe the care pediatric HS patients receive in the ED compared to both HS management guidelines and the management of pediatric skin and soft tissue abscess (SSTA) patients. METHODS: We performed a retrospective chart review of pediatric HS and SSTA patients who presented to a single pediatric ED. Demographic and ED encounter data including medications, procedures, recommendations, consults, and referrals were collected. RESULTS: 58 HS and 175 SSTA charts were reviewed. 69.5% of patients were female and 93.6% were African American/Black. 29.3% of HS and 61.7% of SSTA encounters involved incision and drainage (I&D); 62.1% of HS and 70.1% of SSTA encounters involved the prescription or administration of oral clindamycin; 3.4% of HS and 0.6% of SSTA encounters involved dermatology consultation in the ED; and 22.4% of HS and 5.1% of SSTA encounters involved outpatient referrals to dermatology. CONCLUSIONS: Our data reveal a pediatric HS and SSTA population that is predominantly female and African American/Black. Significant differences were found in the average ages and number of lesions between HS and SSTA patients. I&D and oral clindamycin were the most common treatments across groups; however, I&D was performed significantly more frequently among SSTA encounters than HS encounters. Our results suggest that subtle knowledge gaps may exist in ED provider management of pediatric HS.

ABSTRACT

PURPOSE: Population newborn genetic screening for hypertrophic cardiomyopathy (HCM) is feasible, however its benefits, harms, and cost-effectiveness are uncertain. METHODS: We developed a microsimulation model to simulate a US birth cohort of 3.7 million newborns. Those identified with pathogenic/likely pathogenic variants associated with increased risk of HCM underwent surveillance and recommended treatment, whereas in usual care, individuals with family histories of HCM underwent surveillance. RESULTS: In a cohort of 3.7 million newborns, newborn genetic screening would reduce HCM-related deaths through age 20 years by 44 (95% uncertainty interval [UI] = 10-103) however increase the numbers of children undergoing surveillance by 8127 (95% UI = 6308-9664). Compared with usual care, newborn genetic screening costs $267,000 per life year saved (95% UI, $106,000 to $919,000 per life year saved). CONCLUSION: Newborn genetic screening for HCM could prevent deaths but at a high cost and would require many healthy children to undergo surveillance. This study shows how modeling can provide insights into the tradeoffs between benefits and costs that will need to be considered as newborn genetic screening is more widely adopted.

ABSTRACT

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and resulting COVID-19 (coronavirus disease 2019) pandemic have required mass diagnostic testing, often taking place in testing sites within hospitals, clinics, or at satellite locations. To establish the potential of SARS-CoV-2 aerosol transmission and to identify junctures during testing that result in increased viral exposure, aerosol and surface samples were examined for the presence of SARS-CoV-2 RNA from locations within Nebraska Medicine COVID-19 testing and vaccine clinics. Aerosols containing SARS-CoV-2 RNA detected within clinics suggest viral shedding from infected individuals. SARS-CoV-2 RNA detection in aerosol samples was shown to correlate with clinic operation and patient infection, as well as with community infection findings. Additionally, SARS-CoV-2 RNA was detected in surface samples collected from clinics. The presence of SARS-CoV-2 RNA in aerosols in these clinics supports the continued use of respiratory protection and sanitization practices for healthcare workers, and other workers with public facing occupations.

ABSTRACT

Vitiligo-like changes are an uncommon cutaneous manifestation of graft-versus-host disease (GVHD). We report three cases and review the literature of pediatric patients with vitiligo-like changes associated with GVHD. Improved characterization of this phenomenon may lend insight into the biologic pathways that underlie both vitiligo and GVHD.

ABSTRACT

BACKGROUND: Radiation Therapists (RTs) are a key professional grouping in the delivery of health services for cancer patients. The education of RTs in New Zealand has evolved in response to regulatory and clinical workforce requirements. To date, it has lacked a fundamental underpinning of educational theory. Stakeholders, including students, were canvassed for their perspectives on the drivers behind the current curriculum with a view to developing theory which could shape future curricular development. METHODS: A focus group was conducted with eight student RTs enrolled at the time of the study. A process driven by Constructivist Grounded Theory principles was adopted for the analysis of the resulting data. RESULTS: Four themes were established to represent the data: "Being" is prized over "doing", Change is inevitable, A framework for Professional Identity formation and Modelling is key to learning. CONCLUSIONS: There is utility in exploring the student perspective around curriculum. The data suggest that students on this programme are engaged with the process of preparing for practice and the connected learning experiences. There is a focus on the patient and the personal values and qualities which result from that focus. While specialist knowledge and technical skills are required for delivering patient care, it is fully expected those aspects of the clinical role will significantly change over time. Even at this early stage in their careers, students recognise the development and need for professional identity formation. Role models are perceived to be a vital part of student learning, be they positive or negative. Scrutiny of the study findings provides reason to question some assumptions which are sometimes made about student practitioners based on factors such as age and gender and the assumed universal ability of practitioners to teach the next generation. The perspectives gained inform the next stage of data collection from this group and theory building that will be reported outside the confines of this article.

ABSTRACT

Granuloma annulare (GA) is a cutaneous inflammatory disorder of unknown cause, typically characterized by an annular arrangement of dermal papules and nodules. While GA in adults has been linked to diabetes mellitus (DM) and other conditions, these associations have been less studied in children. A retrospective chart review was conducted of all pediatric patients diagnosed with GA at an urban academic institution over a 7-year period. A total of 47 patients were reviewed. Of these, 41 (85.1%) patients had localized GA, 3 (6.38%) had subcutaneous GA, 2 (4.26%) had generalized GA, and 1 (2.13%) had both localized and subcutaneous GA. The extremities were the most common site of involvement across all morphologies. Atopic conditions were determined in 23 (48.9%) patients, 16 (34.0%) of which had asthma, either alone or in conjunction with atopic dermatitis or allergic rhinitis. None of the patients carried a diagnosis of DM, and all 11 patients who were tested within 3 years of the documented visit had normal results. In summary, this retrospective series characterizes the presentation of pediatric GA and highlights a potential association with atopy. An association with DM was not observed.

ABSTRACT

BACKGROUND/OBJECTIVES: Follicular keratosis (FK) is a poorly understood disorder presenting with multiple, grouped hyperkeratotic follicular papules typically affecting the chin or jawline. This study describes the clinical presentation, histopathology, management, and outcomes of a series of pediatric patients of color with FK of the face, thought to be related to rubbing or friction on the skin. METHODS: Retrospective review of 20 pediatric patients with FK of the face who presented to our pediatric dermatology practice between April 2019 and October 2021. RESULTS: Twenty patients (mean age 12.1 years, 13 females), all self-identified as Black/African American, were included. All presented with an initially asymptomatic, hyperpigmented patch containing multiple hyperkeratotic follicular papules, located on the cheek, chin, upper lip, and/or jawline. Five patients endorsed a history of rubbing the site. Nine patients had onset of the lesions during the COVID-19 pandemic. Treatments included topical vitamin D analogs, corticosteroids, and/or retinoids. Topical vitamin D analogs and retinoids improved the texture and hyperpigmentation of the follicular lesions in only four patients, while topical corticosteroids had no effect. Histopathological examination of two patients revealed multiple dilated follicles containing keratinized material and associated with a sparse dermal inflammatory infiltrate in one patient and granulomatous inflammation within the dermis in the other. CONCLUSIONS: In our cohort of pediatric patients with FK, patients of color were preferentially affected, and all cases were associated with hyperpigmentation. Some patients presented during the COVID-19 pandemic suggesting that friction from facial mask wearing may have induced or exacerbated this uncommon condition.

ABSTRACT

Herpes zoster is rare in healthy and immunocompetent children. While disseminated presentations of zoster are often concerning for underlying immunodeficiency, non-disseminated zoster can also be a presenting illness in such patients. Here, we report a case of non-disseminated herpes zoster in a presumably healthy immunized child that led to a diagnosis of human immunodeficiency virus infection.
