High-income ZIP codes in New York City demonstrate higher case rates during off-peak COVID-19 waves.

Introduction: Our study explores how New York City (NYC) communities of various socioeconomic strata were uniquely impacted by the COVID-19 pandemic. Methods: New York City ZIP codes were stratified into three bins by median income: high-income, middle-income, and low-income. Case, hospitalization, and death rates obtained from NYCHealth were compared for the period between March 2020 and April 2022. Results: COVID-19 transmission rates among high-income populations during off-peak waves were higher than transmission rates among low-income populations. Hospitalization rates among low-income populations were higher during off-peak waves despite a lower transmission rate. Death rates during both off-peak and peak waves were higher for low-income ZIP codes. Discussion: This study presents evidence that while high-income areas had higher transmission rates during off-peak periods, low-income areas suffered greater adverse outcomes in terms of hospitalization and death rates. The importance of this study is that it focuses on the social inequalities that were amplified by the pandemic.

A Case Report of Steroid-Induced Angioedema and Urticaria.

Physicians regularly use corticosteroids to treat various conditions, attributing their anti-inflammatory and immunosuppressive properties. Cases of allergic sensitivity reactions and dermatitis induced by corticosteroids are relatively uncommon. We present a case regarding an 81-year-old male with a history of actinic keratosis, atopic dermatitis, and psoriasis, who experienced a Type I hypersensitivity reaction with facial angioedema and urticaria on his axilla, torso, and popliteal fossa that developed after treatment with oral prednisolone. This episode also exacerbated his previously diagnosed psoriasis. To treat psoriasis, a dermatologist prescribed clobetasol topical ointment, which did not alleviate the symptoms; instead, it only exacerbated the rash, and he was subsequently referred for corticosteroid allergy testing. North American 85 Comprehensive Series patch testing revealed a positive test for various classes of steroids, including clobetasol-17-propionate, budesonide, and dexamethasone, thus proving a T cell-mediated allergy to corticosteroids.

Gross Hematuria and Lower Urinary Tract Symptoms Associated With Military Burn Pits Exposures in US Veterans Deployed to Iraq and Afghanistan.

OBJECTIVE: The aim of the study is to describe rates of hematuria and other lower urinary tract symptoms, including self-reported cancer rates, among veterans postburn pits emissions exposure during deployment to Iraq and Afghanistan. METHODS: US post-9/11 veterans with burn pits emissions exposure confirmed via DD214 forms in the Burn Pits360.org Registry were sent a modified survey. Data were deidentified and anonymously coded. RESULTS: Twenty-nine percent of the 155 respondents exposed to burn pits self-reported seeing blood in their urine. The average index score of our modified American Urological Association Symptom Index Survey was 12.25 (SD, 7.48). High rates of urinary frequency (84%) and urgency (76%) were self-reported. Bladder, kidney, or lung cancers were self-reported in 3.87%. CONCLUSIONS: US veterans exposed to burn pits are self-reporting hematuria and other lower urinary tract symptoms.

A Case Report of Allergic Hypersensitivity to Color Additives in Slurpee® Beverages.

Introduction: Many commercially available foods and beverages contain color additives to which patients may develop allergic hypersensitivity. Several color additives currently approved for commercial sale in the United States have raised health concerns to a varying degree as testing and evidence of carcinogenicity, genotoxicity, and hypersensitivity has thus far been inadequate. Common uses for color additives include baked goods (eg, cakes, pastries, candy), flavored dairy products such as yogurt, sports-themed drinks (eg, Gatorade® Fruit Punch), and red-dyed Slurpee® beverages. Methods: We present the case of a patient who experienced color additive-related allergic hypersensitivity reactions after consumption of Slurpee® beverages, which may place her at risk when consuming other commercially available beverages and food products containing color additives. Percutaneous skin testing and an oral challenge were administered using three different red color additives (two color additives for skin testing and one color additive for the oral challenge). Results: The specific color additive precipitating her symptoms was not conclusively identified. Review of the literature acknowledges the idea that further research into color additive-related allergy should be conducted as there are many commercially available color additives that can elicit hypersensitivity reactions after consumption. Conclusion: Current research shows that of the red color additives available, Citrus Red, Red No. 3, and Red No. 40 are recognized to elicit such reactions. In order to lessen the burden of color additive-related hypersensitivity in the general population, public education, increased research, and subsequent regulations should be implemented.

Attenuation of Human Growth Hormone-Induced Rash With Graded Dose Challenge.

Adult growth hormone (GH) deficiency is rare and requires replacement with extrinsic/synthetic injection. GH hypersensitivity has been reported; specifically, atopic patients may develop rashes from somatotropin therapy. Allergic and non-allergic skin reactions to recombinant human GH are uncommon and infrequently reported. We describe a graded-dose challenge with intravenous Norditropin® in a 65-year-old atopic adult woman who developed a severe whole-body rash with Norditropin FlexPro® administration on several occasions but was negative on skin-prick testing to Norditropin® percutaneously and intradermally, but the patch testing was positive for gold and nickel. The patient was registered as a direct admission to the emergency room at a university hospital for a rapid antigen coronavirus disease 2019 (COVID-19) testing after having received two COVID-19 vaccinations and re-testing four months after vaccination. She was then directly admitted to a non-COVID-19 intensive care unit with direct bedside supervision by a registered nurse and a physician board certified in internal medicine, allergy/immunology, and pulmonary diseases. The patient brought a Norditropin® pen which our pharmacy team attached to a compatible syringe for dilutions. A graded dose challenge at a final dosage of 0.1 mL was performed and the patient was monitored for allergic and other adverse drug reactions, which did not occur. At the time of writing this case report, the patient has been maintained on Norditropin FlexPro® 0.1 mL and has not experienced any adverse reactions, including recurrent skin eruptions. The case presented is the first to describe a patient who successfully tolerated a graded dose challenge of an adult patient to GH replacement therapy (as Norditropin®) under supervision in an intensive care unit, whereas prior to reporting of this case, a graded dose challenge to GH replacement therapy had only been successfully performed in a child using another formulation of somatotropin (Humatrope®). Hence, this case lends support that graded dose challenge with somatotropin analogs may be considered for patients with isolated GH deficiency such as in the case presented here.

Iraq/Afghanistan war lung injury reflects burn pits exposure.

This descriptive case series retrospectively reviewed medical records from thirty-one previously healthy, war-fighting veterans who self-reported exposure to airborne hazards while serving in Iraq and Afghanistan between 2003 and the present. They all noted new-onset dyspnea, which began during deployment or as a military contractor. Twenty-one subjects underwent non-invasive pulmonary diagnostic testing, including maximum expiratory pressure (MEP) and impulse oscillometry (IOS). In addition, five soldiers received a lung biopsy; tissue results were compared to a previously published sample from a soldier in our Iraq Afghanistan War Lung Injury database and others in our database with similar exposures, including burn pits. We also reviewed civilian control samples (5) from the Stony Brook University database. Military personnel were referred to our International Center of Excellence in Deployment Health and Medical Geosciences, Donald and Barbara Zucker School of Medicine at Hofstra/Northwell under the auspices of Northwell IRB: 17-0140-FIMR Feinstein Institution for Medical Research "Clinicopathologic characteristics of Iraq Afghanistan War Lung Injury." We retrospectively examined medical records, including exposure data, radiologic imaging, and non-invasive pulmonary function testing (MGC Diagnostic Platinum Elite Plethysmograph) using the American Thoracic Society (ATS) standard interpretation based on Morgan et al., and for a limited cohort, biopsy data. Lung tissue, when available, was examined for carbonaceous particles, polycyclic aromatic hydrocarbons (Raman spectroscopy), metals, titanium connected to iron (Brookhaven National Laboratory, National Synchrotron Light Source II, Beamline 5-ID), oxidized metals, combustion temperature, inflammatory cell accumulation and fibrosis, neutrophil extracellular traps, Sirius red, Prussian Blue, as well as polarizable crystals/particulate matter/dust. Among twenty-one previously healthy, deployable soldiers with non-invasive pulmonary diagnostic tests, post-deployment, all had severely decreased MEP values, averaging 42% predicted. These same patients concurrently demonstrated abnormal airways reactance (X5Hz) and peripheral/distal airways resistance (D5-D20%) via IOS, averaging - 1369% and 23% predicted, respectively. These tests support the concept of airways hyperresponsiveness and distal airways narrowing, respectively. Among the five soldiers biopsied, all had constrictive bronchiolitis. We detected the presence of polycyclic aromatic hydrocarbons (PAH)-which are products of incomplete combustion-in the lung tissue of all five warfighters. All also had detectable titanium and iron in the lungs. Metals were all oxidized, supporting the concept of inhaling burned metals. Combustion temperature was consistent with that of burned petrol rather than higher temperatures noted with cigarettes. All were nonsmokers. Neutrophil extracellular traps were reported in two biopsies. Compared to our prior biopsies in our Middle East deployment database, these histopathologic results are similar, since all database biopsies have constrictive bronchiolitis, one has lung fibrosis with titanium bound to iron in fixed mathematical ratios of 1:7 and demonstrated polarizable crystals. These results, particularly constrictive bronchiolitis and polarizable crystals, support the prior data of King et al. (N. Engl. J. Med. 365:222-230, 2011) Soldiers in this cohort deployed to Iraq and Afghanistan since 2003, with exposure to airborne hazards, including sandstorms, burn pits, and improvised explosive devices, are at high risk for developing chronic clinical respiratory problems, including: (1) reduction in respiratory muscle strength; (2) airways hyperresponsiveness; and (3) distal airway narrowing, which may be associated with histopathologic evidence of lung damage, reflecting inhalation of burned particles from burn pits along with particulate matter/dust. Non-invasive pulmonary diagnostic tests are a predictor of burn pit-induced lung injury.

Healthcare Economics of a Coronavirus Disease 2019 Pop-Up Vaccination Center.

Introduction: Creation of pop-up vaccination sites at trusted community locations has been encouraged to address vaccine hesitancy and provide equitable access to COVID-19 vaccination in minority communities. This study sought to study the healthcare economics of a community-based COVID-19 pop-up vaccination center in terms of the following: costs associated with operating the vaccination center, analysis of billing data from patients who received the Moderna COVID-19 vaccine, and costs of hospitalization for COVID-19 which may be avoided with widespread vaccination. Methods: The pop-up vaccination center was located in Port Jefferson Station, NY, USA. Costs associated with operation of the COVID-19 pop-up vaccination center were quantified, itemized, and tabulated. Current Procedural Technology codes were used to identify patients who received the Moderna COVID-19 vaccine. Billing data were quantified for the cohort as well as per each patient to receive the vaccine. Costs associated with provision of urgent care, emergency, and hospital services to patients with COVID-19 were obtained. Results: The total cost to operate the vaccination center was $25,880. The vaccination center administered the initial dose of the Moderna COVID-19 vaccine to N=251 patients between March and May, 2021. The standard hospital costs for patients admitted to the medical ICU due to COVID-19 ranged from $8,913 to $190,714, per patient. Conclusion: Since the Moderna COVID-19 vaccine series is effective in preventing hospitalization for 93% of patients, this community-based vaccination center's administration of the vaccine series to 240 patients meant aversion of hospitalization due to COVID-19 related morbidity for 223 patients. Therefore, the true impact of this vaccination center, measured in averted hospital costs, ranges from $1,987,599 to $42,529,222.

Plausible Role of Asthma Biological Modifiers in the Treatment of Eosinophilic Esophagitis.

Eosinophilic esophagitis (EoE) is a T-helper type-2 (Th2/T2) cell-mediated disease characterized by 15 or more eosinophils per high-powered esophageal biopsy microscopy field (eos/hpf), excluding other causes. EoE is often clinically characterized by symptoms such as dysphagia, nausea, food impaction, and chest pain that do not respond to antacids. Two-thirds of patients are unresponsive to proton pump inhibitors (PPIs). Steroids may be effective but pose long-term health risks and can lose efficacy in patients with serum eosinophilia greater than 1,500 cells/µL. Because EoE is not IgE-mediated, allergy skin testing for food may benefit a subset of patients. These therapies have shortcomings, which necessitate further investigation. Herein, we report a patient successfully treated with benralizumab (anti-IL-5Rα), demonstrating a potential solution to the lack of effective treatments for EoE.

The Case of a Janitorial Supervisor With Occupational Asthma Complicated by the Mixed Colonization of the Respiratory Tract by Candida albicans and Alternaria spp.

Patients on immunosuppressant agents, including oral corticosteroids, are susceptible to fungal colonization despite being otherwise immunologically intact. This case report highlights a state-of-the-art biological modifier therapy for the complex care of a patient with refractory occupational asthma, allergic rhinitis, and mixed fungal colonization. A dyspneic 38-year-old male janitor with steroid-dependent occupational asthma refractory to omalizumab therapy was colonized with Candida and Alternaria following a promotion to a managerial position in a moldy office. He was treated with itraconazole and systemic steroids. Pulmonary workup revealed moderate obstructive ventilatory defect, peripheral airway hyperresponsiveness, and eosinophilic airway inflammation. Three additional biological modifiers (reslizumab, benralizumab, and dupilumab) were administered to this patient. His asthma was ultimately controlled with reslizumab and dupilumab. Fractional exhaled nitric oxide (FeNO) normalized after dupilumab monotherapy, enabling the patient to taper off chronic prednisone therapy. Various occupational exposures are crucial epidemiologic factors related to infection and go hand-in-glove with long-term prednisone treatment towards increasing susceptibility to fungal colonization. Steroid-sparing anti-interleukin-5 (IL-5) agents and dupilumab should be considered as alternative treatment options for patients, such as ours, with eosinophilic, prednisone-dependent asthma refractory to omalizumab therapy.

Allergy and Lung Injury Among Rescue Workers Exposed to the World Trade Center Disaster Assessed 17 Years After Exposure to Ground Zero.

OBJECTIVE: Investigate the following in rescue and cleanup workers exposed to the World Trade Center (WTC) disaster 17 years post-fallout: (1) allergic hypersensitivity; (2) spirometry; (3) impulse oscillometry; and (4) the reversibility of airway hyperresponsiveness and distal airways narrowing pre- and post-bronchodilator. METHODS: In subjects (n = 54) referred to our clinic from the WTC Health Program for management of allergy-immunology services, environmental allergy testing, impulse oscillometry (IOS), and spirometry results were retrospectively reviewed to determine the long-term impact of exposure to the WTC fallout. RESULTS: Rescue and cleanup workers exposed to the WTC fallout had a high incidence of allergic hypersensitivity and had evidence of permanent small airways dysfunction characterized by distal airways narrowing and airway hyperresponsiveness. CONCLUSION: Following exposure to the WTC disaster, the patients in our cohort developed allergic hypersensitivity and severe lung injury with only partial reversibility.

Health Effects of Climate Change-induced Wildfires and Heatwaves.

Global warming is a phenomenon that is affecting society in sundry ways. As of 2017, Earth's global surface temperature increased 0.9°C compared to the average temperature in the mid-1900s. Beyond this change in temperature lies significant threats to human health in the form of natural disasters and extreme temperatures. One natural disaster that has been receiving much more attention as of 2010 is the ignition and spread of wildfires. Warmer climates lead to drier conditions, providing ideal kindling for the rapid spread of these infernos. The dangers that these intense fires pose are twofold: first, the fire causes mass property damage, physical harm, or death to the people unfortunate enough to be caught in the blaze; second, the health hazards of smoke inhalation and the emotional strain of losing one's possessions cause immense physical and emotional harm to the fire's victims. Another health hazard that is becoming more common due to global warming is heatwave exposure. The heat provides an ideal environment for certain pathogens to thrive, increases people's risk of developing temperature-related health conditions, and could exacerbate many preexisting diseases. The increase in frequency and intensity of these extreme weather conditions calls for devotion of resources to fire prevention and public health measures related to smoke inhalation and heat exposure.

Rux largely restores lungs in Iraq PM-exposed mice, Up-regulating regulatory T-cells (Tregs).

Background Military personnel post-deployment to Iraq and Afghanistan have noted new-onset respiratory illness. This study's primary objective was to further develop an animal model of Iraq Afghanistan War Lung Injury (IAW-LI) and to test a novel class of anti-injury drug called RuX. Methods Particulate Matter (PM) samples were obtained in Iraq then characterized by spectromicroscopy. C57BL/6 mice underwent orotracheal instillation with PM, followed by drinkable treatment with RuX. Lung histology, inspiratory capacity (FlexiVent), thymic/splenic regulatory T cell (Treg) number, and whole-lung genomics were analyzed. Results Tracheal instillation of Iraq PM led to lung septate thickening and lymphocytic inflammation. PM-exposed mice had suppression of thymic/splenic regulatory T-cells (Tregs). Drinking RuX after PM exposure attenuated the histologic lung injury response, improved lung inspiratory capacity, and increased Tregs. Pooled whole lung genomics suggest differences among gene expression of IL-15 among control, PM, and PM + RuX groups. Conclusions RuX, a ruthenium and alpha-lipoic acid complex, attenuates lung injury by improving histology and inspiratory capacity via upregulation of Tregs in Iraq PM-exposed C57BL/6. Plausible genomic effects may involve IL-15 whole lung gene expression.

The Role of Iraqi Dust in Inducing Lung Injury in United States Soldiers-An Interdisciplinary Study.

United States soldiers are returning from the Greater Middle East with respiratory illnesses ranging from new onset asthma to constrictive bronchiolitis. The etiology of the diseases is unknown. A study was conducted to determine the possible role of local mineral dust in the development of abnormal respiratory illnesses in soldiers during and after deployment in Iraq. A dust sample obtained in proximity to a burn pit in Camp Victory, Iraq, (CVD) was characterized both chemically and mineralogically. For comparison, a dust sample from Fort Irwin, California, (FID) was also collected. The ability of the dust samples to generate reactive oxygen species (ROS) was quantified, as well as their ability to generate an inflammatory stress response (ISR) in human lung epithelial cells. Both samples are comprised of common silicate and carbonate minerals and contain heavy metals with concentration ranges expected for mineral dust. The ISR generated by each sample was within the range of inert material with the minimal stress generated associated with the carbonate phases. The findings based on this one sample suggest that the origin of the disease is not driven by the particles ability to generate ROS. However it is likely that particle overload, and associated complications, or endotoxin contribute extensively to pathogenesis.

Enhanced Mortality to Metastatic Bladder Cancer Cell Line MB49 in Vasoactive Intestinal Peptide Gene Knockout Mice.

To identify if the absence of the vasoactive intestinal peptide (VIP) gene enhances susceptibility to death from metastatic bladder cancer, two strains of mice were injected with MB49 murine bladder cancer cells. The growth and spread of the cancer was measured over a period of 4 weeks in C57BL/6 mice and 5 weeks in VIP knockout (KO) mice. A Kaplan-Meier plot was constructed to compare control C57BL/6 mice and C57BL/6 mice with MB49 vs. VIP KO controls and VIP KO mice with MB49. The wild-type (WT) strain (C57BL/6) contained the VIP gene, while the other strain, VIP knockout backcrossed to C57BL/6 (VIP KO) did not and was thus unable to endogenously produce VIP. VIP KO mice had increased mortality compared to C57BL/6 mice at 4 weeks. The number of ulcers between both groups was not statistically significant. In vitro studies indicated that the presence VIP in high doses reduced MB49 cell growth, as well as macrophage inhibitory factor (MIF), a growth factor in bladder cancer cells. These findings support the concept that VIP may attenuate susceptibility to death from bladder cancer, and that it exerts its effect via downregulation of MIF.

A plane screw fixation is a nidus for Paecilomyces sinusitis in a patient with aspirin exacerbated respiratory disease.

Titanium plane screw fixation of the frontal sinus is an approach used by otolaryngologists to obliterate this space in an attempt to reduce sinus infections. In this case, however, the titanium used became a nidus of infection which cultured the fungus Paecilomyces. The patient also had a hypersensitivity reaction to mold with positive skin tests and IgE, as well as eosinophilic esophagitis. Treatment entailed anti-fungals, anti-IgE, and fungal immunotherapy to multiple fungal antigens prevalent to the geographic region. The patient also had aspirin exacerbated respiratory disease which responded to aspirin desensitization. Her symptoms resolved after 3 months.
