Charcot-Leyden crystals (CLCs) are Galectin-10 protein crystals that can form after eosinophils degranule. CLCs can appear and persist in tissues from patients with eosinophilic disorders, such as asthma, allergic reactions, fungal, and helminthic infections. Despite abundant reports of their occurrence in human disease, the inflammatory potential of CLCs has remained unknown. Here we show that CLCs induce IL-1β release upon their uptake by primary human macrophages in vitro, and that they induce inflammation in vivo in mouse models of acute peritonitis and bronchitis. CLC-induced IL-1β was dependent on NLRP3 and caspase-1, and their instillation in inflammasome reporter mice promoted the ...

Pharmaceuticals that suppress HIV-1 viremia preserve CD4+ T cells and prevent AIDS. Nonetheless, HIV-1 infected people taking these drugs have chronic inflammation attributable to persistent disruption of intestinal barrier function with increased rates of cardiovascular mortality. To better understand the etiology of this inflammation we examined the effect of HIV-1 infection on innate lymphoid cells (ILCs). These innate immune counterparts of T cells lack clonotypic antigen receptors, classify according to signature transcription factors and cytokines, and maintain homeostasis in inflamed tissues. ILCs have been defined, in part, by the IL-7Rα, CD127. Here we report that the vast majority of type ...

Type 1 Diabetes, Dan Bornstein

Global Issues in Public Health

The aim of this research was to increase the awareness of this disease and show the range of which it travels. Type 1 Diabetes, although not as common as Type 2 Diabetes, is a very serious disease present well around the world. Between the two forms, there are nearly 1.5 million people diagnosed with diabetes each year (American Diabetes Association, 2015). Northern European countries tend to have the highest prevalence of Type 1 diabetes. Younger children on average ages of 0-14 years, are most frequently struck with this disease (American Diabetes Association, 2015). With the given amount of symptoms ...

We identified the risk factors of LBW and geographical differences in LBW incidence in 30 Chinese provinces in the present study.This study was a population-based, retrospective cohort study performed in 30 Chinese provinces. We used data from the free National Pre-pregnancy Checkups Project, which is a countrywide population-based retrospective cohort study. To identify regional differences in LBW incidence, we used the Qinling-Huaihe climate line to divide China into northern and southern sections and the Heihe-Tengchong economic line to divide it into eastern and western sections. Multivariate ...


Prior Voluntary Wheel Running Prevents Memory Deficits And Enhanced Neuropathic Pain Presenting After Morphine Dosing Ceases, Nathan Plattner 2018 University of Colorado, Boulder

Prior Voluntary Wheel Running Prevents Memory Deficits And Enhanced Neuropathic Pain Presenting After Morphine Dosing Ceases, Nathan Plattner

Undergraduate Honors Theses

Clinical research studies show that chronic pain is a prevalent, difficult affliction to manage. The most common management for chronic pain is opioids, which research is showing to paradoxically induce persistent, worsened pain states as well as potentially having negative effects on memory. The necessity for understanding chronic pain and drug management options is apparent, and research is aiming to do just that. Exercise is one potential preventative measure or post hoc treatment possibility for chronic pain, as abundant research has shown. Knowledge of the interactions between exercise, morphine dosing, and peripheral nerve injury is nonexistent. As such, we desired ...

Clinicopathologic Consensus Study Of Gray Zone Lymphoma With Features Intermediate Between Dlbcl And Classical Hl, Monika Pilichowska, Bruce A. Woda, Elaine S. Jaffe, Andrew M. Evens

Open Access Articles

Gray zone lymphoma (GZL) is described as sharing features with classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL). However, there remains complexity in establishing diagnosis, delineating prognosis, and determining optimum therapy. Sixty-eight cases diagnosed as GZL across 15 North American academic centers were evaluated by central pathology review to achieve consensus. Of these, only 26 (38%) were confirmed as GZL. Morphology was critical to GZL consensus diagnosis (eg, tumor cell richness); immunohistochemistry showed universal B-cell derivation, frequent CD30 expression, and rare Epstein-Barr virus (EBV) positivity (CD20(+), 83%; PAX5(+), 100%; BCL6(+), 20%; MUM1(+), 100%; CD30(+), 92%; EBV(+), 4%). Forty-two ...

Stress cardiomyopathy (SCM) is a unique cardiac disorder that more often occurs in women. SCM presents in a similar fashion as acute myocardial infarction (AMI), with chest pain, ECG changes, and congestive heart failure. The primary distinguishing feature is the absence of thrombotic coronary occlusion in SCM. How this reduction in cardiac function occurs in the absence of coronary occlusion remains unknown. Therefore, we tested the hypothesis that a targeted proteomic comparison of patients with acute SCM and AMI might identify relevant mechanistic differences. Blood was drawn in normal controls (n = 6), women with AMI (n = 12), or women with ...


Sepsis, Sarah Jones 2017 Otterbein University

Sepsis, Sarah Jones

Nursing Student Class Projects (Formerly MSN)

Sepsis is a dysregulation of the inflammatory response, termed systemic inflammatory response syndrome or SIRS, caused by stimulation of an infectious process. Sepsis often leads to organ dysfunction and increased morbidity, mortality and financial burdens. The goal of treatment is to initiate appropriate antimicrobial therapies, target the underlying infection, optimize intravascular volume, provide fluid resuscitation and maintain adequate perfusion and stroke volume (Taeb, Hooper & Marik, 2017).

Timing of treatment and early detection of sepsis is critical to patients with early warning signs. Sharing this information and potentially making a difference in the outcomes of patients presenting with early signs of ...

Microscopic colitis (MC) is an inflammatory condition of the large bowel that is associated with chronic, nonbloody diarrhea. Colonoscopy usually demonstrates normal mucosa, while tissue biopsy reveals intraepithelial lymphocytes or a subepithelial collagen band. Although no specific antibody has been discovered, MC is associated with several autoimmune disorders such as celiac disease, Hashimoto's thyroiditis, and rheumatoid arthritis. There are only a small number of case reports documenting possible hereditary MC cases, but up to 12% of patients with MC have a family history of inflammatory bowel disease. Other associations include proton pump inhibitor use, cigarette smoking, HLA-DQ2/86, and ...

Performance Of Non-Invasive Tests To Predict Significant Liver Fibrosis In Patients With Morbid Obesity, Ahmed Bakhshwin, Patricia Latham 2017 George Washington University

Performance Of Non-Invasive Tests To Predict Significant Liver Fibrosis In Patients With Morbid Obesity, Ahmed Bakhshwin, Patricia Latham

GW Research Days 2016 - Present

Non-Alcoholic Fatty Liver Disease (NAFLD) affects more than 90% of patients with morbid obesity (MO) and approximately 30% have significant liver fibrosis and/or cirrhosis. Liver biopsy is the gold standard for diagnosis of significant liver fibrosis and cirrhosis; however, several non-invasive tests have been suggested to predict the presence or absence of significant liver fibrosis and to avoid liver biopsy in these patients. The aim of this study was to determine the ability of these tests to predict significant liver fibrosis, specifically in patients with MO.

Methods:

Liver biopsies from patients with MO undergoing gastric bypass surgery were studied ...
