Global Health Faculty Publications

BACKGROUND: Adverse birth outcomes, including low birth weight (LBW), defined as <2500 >grams, small-for-gestational-age (SGA), and prematurity, contribute to 60%-80% of infant mortality worldwide and may be related to infections during pregnancy. The aim of this study was to assess whether febrile human rhinovirus (HRV) illness is associated with adverse birth outcomes.

METHODS: Active household-based weekly surveillance was performed for respiratory illness episodes in pregnant women as part of a community-based, prospective, randomized trial of maternal influenza immunization in rural Nepal. Rhinovirus (HRV) febrile illness episodes were defined as fever plus cough, sore throat, runny nose, and/or myalgia with HRV detected …

African Americans have higher rates of asthma prevalence, morbidity, and mortality in comparison with other racial groups. We sought to characterize endotypes of childhood asthma severity in African American patients in an inner-city pediatric asthma population. Baseline blood neutrophils, blood eosinophils, and 38 serum cytokine levels were measured in a sample of 235 asthmatic children (6-17 years) enrolled in the NIAID (National Institute of Allergy and Infectious Diseases)-sponsored Asthma Phenotypes in the Inner City (APIC) study (ICAC (Inner City Asthma Consortium)-19). Cytokines were quantified using a MILLIPLEX panel and analyzed on a Luminex analyzer. Patients were classified as Easy-to-Control or …

Singapore : Severe Acute Respiratory Syndrome (Sars), Dexter Lipps

Global Public Health

Singapore ranks as one of the healthiest countries in the world and its healthcare system has been regarded as one of the most efficient. While a minority of the population experience any chronic diseases such as diabetes or asthma, one illness, severe acute respiratory syndrome or SARS has been prevalent in the country since the global outbreak in 2003. SARS is a virus causing disease that is easily transmitted through the air. In 2003, Singapore, along with much of the world, saw a high rate of infection for the disease. An in depth look revealed that three women traveling home …

New Zealand : Mumps Outbreak, Kathryn Evans

Global Public Health

The purpose of this Health Brief is to discuss the outbreak of mumps in New Zealand during the summer of 2017. The year saw more cases than the past sixteen years combined. The reason that New Zealand, a high-income country that generally does not struggle with communicable diseases, may be experiencing this outbreak is low vaccination rates in the 1990’s. It appears that there was a decline in coverage for the MMR immunization at this time due to several factors. These include a transition in the timing of the second dose of MMR, a change from four years to eleven …

Pseudomembranous Tracheitis Caused By Aspergillus Fumigatus In The Setting Of High Grade T-Cell Lymphoma, Prashant Malhotra, Karan Singh, Paul Gill, Sonu Sahni, Mina Makaryus, Arunabh Talwar

Touro College of Osteopathic Medicine (New York) Publications and Research

Pseudomembranous tracheitis (PMT) is a rare condition most commonly caused by fungal or bacterial infection that is characterized by a pseudomembrane that partially or completely covers the tracheobronchial tree. PMT is most commonly found in immunocompromised patient populations, such as post-chemotherapy, AIDS, post-transplant and hematological malignancies. Due to its rarity, PMT is often not included in the differential diagnosis. This case describes a 65 year old male with persistent fever and refractory cough despite high dose empiric antibiotics. Subsequent bronchoscopy with biopsy revealed pseudomembranous tracheitis due to Aspergillus fumigatus in the setting of T-cell lymphoma. PMT should be considered in …

Primary Pulmonary Malt Lymphoma Presenting As Non-Resolving Pneumonia, Asma Iftikhar, Albert Magh, Muhammed Azaz Cheema, Sarah Thappa, Sonu Sahni, Stephen Karbowitz

Touro College of Osteopathic Medicine (New York) Publications and Research

Primary lung lymphoma (PLL) is a rare unilateral or bilateral lung disorder that is challenging to diagnose solely based on clinical and radiological presentation. PLL may be misdiagnosed as pneumonia or a lung tumor due to non-specific findings. PLL is most frequently a mucosa-associated lymphoid tissue (MALT) lymphoma, a type of extranodal low-grade B-cell lymphoma most commonly discovered in the gastrointestinal tract. PLL should be considered in the differential diagnosis of non-resolving pneumonias. Herein we present a case of an 84-year-old patient discovered to have a primary pulmonary MALT lymphoma presenting as a non-resolving pneumonia causing a clinical challenge.

Pulmonary rehabilitation (PR) is part of the recommended management plan of pulmonary hypertension (PHTN) and is important to better quality of life and exercise tolerance. This study aimed at determining effectiveness of PR on exercise capacity. Retrospective chart analysis was conducted on patients referred to our PHTN clinic for PR. Patients who had PHTN diagnosed on right heart catheterization (defined by mean pulmonary artery pressure>25 mmHg) and completed a standardized 12-week PR program were considered for the study. Patients’ baseline exercise tolerance was recorded as speed attainable on a treadmill and duration of exercise in minutes. Demographics, age, sex, …

Socioeconomic Status And Its Relationship To Chronic Respiratory Disease, Sonu Sahni, Ankoor Talwar, Sameer Khanijo, Arunabh Talwar

Touro College of Osteopathic Medicine (New York) Publications and Research

Socioeconomic status (SES) is defined as an individual’s social or economic standing, and is a measure of an individual’s or family’s social or economic position or rank in a social group. It is a composite of several measures including income, education, occupation, location of residence or housing. Studies have found a lower SES has been linked to disproportionate access to health care in many diseases. There is emerging data in pulmonary diseases such as COPD, asthma, cystic fibrosis, pulmonary hypertension and other chronic respiratory conditions that allude to a similar observation noted in other chronic diseases. In the setting of …

Hyaluronidase: A Potential New Treatment For Acute Respiratory Distress Syndrome, C. Leblanc, Robert Stern

Touro College of Osteopathic Medicine (New York) Publications and Research

Acute respiratory distress syndrome, also known as diffuse alveolar damage, is an acute injury to the lungs. Patients experience severe shortness of breath and require mechanical ventilation. It is not a specific disease, but an acute lung dysfunction associated with a variety of disorders: pneumonia, shock, sepsis, and trauma. A similar lesion occurs in newborn infants, called hyaline disease of the newborn. It occurs in premature babies and has the same pathophysiological mechanism as acute respiratory distress syndrome. Hyaline membranes are a pathologic feature of acute respiratory distress syndrome, consisting of basophilic structures that coat alveolar surfaces. They prevent oxygen …

Nursing Student Class Projects (Formerly MSN)

Acute respiratory distress syndrome (ARDS) is a condition that involves severe injury to the lung and was first identified during the Vietnam War. Continual research has been performed which has led to multiple treatment modalities. Some treatment modalities are viewed as controversial which proves that more research regarding ARDS needs completed in order to improve patient outcomes. Further education and investment in bedside interventions will continue to improve the clinical treatment and survival rates of affected patients.

Alpha-1 Deficiency: Better Detection May Improve Outcomes For Copd Patients, Angela Schuster

Physician Assistant Scholarly Project Posters

Alpha-1 antitrypsin deficiency (AATD) is a genetic disorder that results in debilitating illnesses like: emphysema, COPD, liver disease, and panniculitis. AATD is highly under-diagnosed based on epidemiologic and population studies that suggest that fewer than 10% of the 60,000-100,000 individuals in the U.S. suspected to have severely deficient alleles have been identified ( Rahaghi et al., 2012). This study examines strategies aimed at improving detection of AATD. The findings indicate that utilizing flags to alert providers of the need for AATD testing initiated by RTs or automated within EMR systems are effective strategies for increasing testing rates and potentially improving …

Alterations in microRNA (miRNA) expression may contribute to COPD pathogenesis. In COPD, lung fibroblast repair functions are altered in multiple ways, including extracellular mediator release. Our prior study revealed miR-503 expression is decreased in COPD lung fibroblasts, although the exact role played by miR-503 is undetermined. The current study examined a role of miR-503 in cytokine, growth factor and fibronectin production by lung fibroblasts from patients with and without COPD. Primary adult lung fibroblasts were isolated from patients with or without COPD. MiR-503 expression and interleukin (IL)-6, -8, PGE2, HGF, KGF, VEGF and fibronectin release were examined with or without …

Nasopharyngeal Microbiome Diversity Changes Over Time In Children With Asthma, Marcos Pérez-Losada, Lamia Alamri, Keith Crandall, Robert J. Freishtat

Pediatrics Faculty Publications

Background

The nasopharynx is a reservoir for pathogens associated with respiratory illnesses such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome of infants and adults during health and disease; less is known, however, about the composition and temporal dynamics (i.e., longitudinal variation) of microbiotas from children and adolescents. Here we use NGS technology to characterize the nasopharyngeal microbiomes of asthmatic children and adolescents (6 to 18 years) and determine their stability over time.

Methods

Two nasopharyngeal washes collected 5.5 to 6.5 months apart were taken from 40 children and adolescents with asthma living in the …

Sin

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death and there is a huge unmet clinical need to identify disease biomarkers in peripheral blood. Compared to gene level differential expression approaches to identify gene signatures, network analyses provide a biologically intuitive approach which leverages the co-expression patterns in the transcriptome to identify modules of co-expressed genes.

METHODS: A weighted gene co-expression network analysis (WGCNA) was applied to peripheral blood transcriptome from 238 COPD subjects to discover co-expressed gene modules. We then determined the relationship between these modules and forced expiratory volume in 1 s (FEV …

Effectiveness And Safety Of The Bronchial Thermoplasty Procedure, Kathy Mohammadi

Physician Assistant Scholarly Project Posters

• Asthma: a heterogeneous disease characterized by chronic airway inflammation resulting in respiratory difficulty.

• Bronchial Thermoplasty (BT): a bronchoscopy procedure that delivers radiofrequency energy to the tissues of airway walls thus heating the tissue, causing ablation to reduce the mass of the airway smooth muscle (ASM), hence attenuating bronchoconstriction.

• BT was designed to decrease, de-bulk or partially eliminate excess smooth muscle tissue in the distal airways, with a subsequent decrease in the number of severe asthma attacks.

• BT is an alternative treatment for patients with severe, uncontrolled asthma in which the airway smooth muscle is eliminated using …

Mc-Ppea As A New And More Potent Inhibitor Of Clp-Induced Sepsis And Pulmonary Inflammation Than Fk866., Peixin Huang, Mark W Lee, Keivan Sadrerafi, Daniel P. Heruth, Li Q. Zhang, Dev Maulik, Shui Qing Ye

Manuscripts, Articles, Book Chapters and Other Papers

Our previous study indicated that overexpression of nicotinamide phosphoribosyltransferase (NAMPT) aggravated acute lung injury, while knockdown of NAMPT expression attenuated ventilator-induced lung injury. Recently, we found that meta-carborane-butyl-3-(3-pyridinyl)-2E-propenamide (MC-PPEA, MC4), in which the benzoylpiperidine moiety of FK866 has been replaced by a carborane, displayed a 100-fold increase in NAMPT inhibition over FK866. Here, we determined the effects of MC4 and FK866 on cecal ligation and puncture (CLP) surgery-induced sepsis in C57BL/6J mice. MC4 showed stronger inhibitory effects than FK866 on CLP-induced mortality, serum tumor necrosis factor α (TNFα) levels, pulmonary myeloperoxidase activity, alveolar injury, and interleukin 6 and interleukin1β messenger …
