BACKGROUND: Non-human primates have been shown to be useful models for Chagas disease. We previously reported that natural T. cruzi infection of cynomolgus macaques triggers clinical features and immunophenotypic changes of peripheral blood leukocytes resembling those observed in human Chagas disease. In the present study, we further characterize the cytokine-mediated microenvironment to provide supportive evidence of the utility of cynomolgus macaques as a model for drug development for human Chagas disease...

INTRODUCTION: Vasovagal syncope (VVS) is a clinical syndrome characterized by transient loss of consciousness and postural tone that is due to a temporary and spontaneously self-terminating global cerebral hypoperfusion. It is known that personality modulates the individual's sensitivity to stressors, and emotional arousal and psychologic uncertainty are conditions contributing to vasodepressor syncope. Therefore it is postulated that personality characteristics of VVS patients could have a role in the pathophysiology of VVS...

Trypanosoma cruzi is the etiologic agent of American trypanosomiasis has broad biological and genetic diversity. Remaining to be studied are polymorphisms of the blood forms and metacyclogenesis of different T. cruzi discrete typing units (DTUs). Our goal was to evaluate the relationship between T. cruzi DTUs, the morphology of blood trypomastigotes, and in vitro metacyclogenesis. T. cruzi strains that pertained to DTUs TcI, TcII, and TcIV from different Brazilian states were used. Parameters that were related to the morphology of eight strains were assessed in thin blood smears that were obtained from mice that were inoculated with blood or culture forms, depending on strain...

BACKGROUND: Electroencephalogram (EEG) waveforms vary widely among individuals, this decreases the usefulness of BIS™ monitors for assessing the effects of propofol. Practically, anesthesia is only seen as too deep when evidence of burst-suppression is seen. We designed an experiment to help towards better assessment of individual anesthetic needs. First, to mark the Ce (effect-site concentration) of propofol at loss of response to calling name and gently shaking shoulders (LOR), we defined Ce-LOR...

Phylogenetic relationships among major lineages of Trypanosoma cruzi are still debatable. Particularly, it is controversial the origin of two main lineages: TcIII and TcIV. Some authors proposed that these lineages have been the result of an ancient hybridization between TcI and TcII, and this was one of the most accepted evolutionary models in the scientific community for several years. In the present paper we analyse several genomes of T. cruzi in order to examine if there is evidence supporting that TcIII is an ancient TcI/TcII hybrid...

Chronotype is largely classified as being morning or evening types according to preference for daily activity and the preferred bedtime. This study examined the relationship between chronotype and temperament/character dimensions among university students. A total of 2857 participants completed the 140-item Temperament and Character Inventory-Revised Short version (TCI-RS) from a 5-score scale as well as the 13-item composite scale for morningness-eveningness (CSM). In this study, we classified chronotype as "morning," "neither," or "evening" types according to CSM scores and compared the scores in terms of 4 temperament dimensions and 3 character dimensions...

The protozoan Trypanosoma cruzi is the causative agent of Chagas disease, a major public health problem in Latin America. This parasite has a complex population structure comprised by six or seven major evolutionary lineages (discrete typing units or DTUs) TcI-TcVI and TcBat, some of which have apparently resulted from ancient hybridization events. Because of the existence of significant biological differences between these lineages, strain characterization methods have been essential to study T. cruzi in its different vectors and hosts...

: 101 Background: NF is an oncologic emergency and has historically resulted in inpatient (inpt) management. The Multinational Association for Supportive Care in Cancer (MASCC) score can be used to identify NF pts at LR for complications who can be safely managed in the outpatient (outpt) setting. Despite established guidelines supporting outpt management of LRNF, provider awareness is low and inpt admission for intravenous antibiotics (abx) continues to be standard of care. METHODS: A multidisciplinary team performed a QI project to improve management of LRNF (baseline cohort of LRNF pts treated from Jan - Mar 2014, N = 13)...

: 29 Background: Patient-centered outcomes are important quality metrics of value-based cancer care. For NSCLC, these include chemotherapy administration within 30 days of death and end of life hospitalizations. Nivolumab was initially FDA approved in March 2015 for second-line therapy of squamous NSCLC and subsequently for non-squamous NSCLC. To evaluate the impact of post-approval nivolumab use on patient-centered outcomes, a retrospective review was performed of patients (pts) with metastatic NSLCC receiving nivolumab at TCI main campus and regional centers...

BACKGROUND: Methods to deliver an antigen into the skin in a painless, defined, and reproducible manner are essential for transcutaneous immunization (TCI). Here, we employed an ablative fractional infrared laser (P.L.E.A.S.E. Professional) to introduce clinically relevant vaccines into the skin. To elicit the highest possible antibody titers with this system, we optimized different laser parameters, such as fluence and pore number per area, and tested various adjuvants. METHODS: BALB/c mice were immunized with Hepatitis B surface antigen (HBsAg) by laser-microporation...

Chronic periodontitis (CP) is an infectious inflammatory disease that affects tooth-supporting structures and in which dental plaque bacteria, immune mechanisms and genetic predisposition play important roles. Interleukin 4 (IL-4) is a key anti-inflammatory cytokine with relevant action in imbalances in inflamed periodontal tissue. Individuals carrying the TCI/CCI genotype (S-haplotype) of the IL-4 gene are 5 times more susceptible to CP, whereas the CTI/TTD genotype (P-haplotype) confers protection against CP...

Trypanosoma cruzi, the agent of Chagas disease exhibits significant genetic diversity. This parasite is divided into six discrete typing units (DTUs) where T. cruzi I (TcI) is the most widespread in the Americas. TcI genotypes have been associated to domestic and sylvatic cycles of transmission (TcIDom and sylvatic TcI). Due to the importance of the enzootic transmission, we determined the frequency of TcI genotypes present in Rhodnius prolixus captured in different regions of the palm A. butyracea to understand the ecology of the disease and the importance of A...

The effect of liver dysfunction on target-controlled infusion (TCI) of propofol remains poorly documented. The pharmacodynamic performance of propofol TCI was evaluated in a cohort of Chinese patients with hepatic insufficiency. Fifty-three patients with hepatic insufficiency were enrolled in the current prospective, observational study. Anesthesia was induced with propofol via TCI to a plasma concentration of 3 µg/ml. Following loss of consciousness (LOC), fentanyl and cisatracurium were administered. Pharmacodynamic parameters were recorded during TCI, including time to LOC, bispectral index (BIS), heart rate (HR) and blood pressure...

The parasitic protozoan Trypanosoma cruzi, the causative agent of Chagas disease, is widely distributed throughout the Americas, from the southern United States (US) to northern Argentina, and infects at least 6 million people in endemic areas. Much remains unknown about the dynamics of T. cruzi transmission among mammals and triatomine vectors in sylvatic and peridomestic eco-epidemiological cycles, as well as of the risk of transmission to humans in the US. Identification of T. cruzi DTUs among locally-acquired cases is necessary for enhancing our diagnostic and clinical prognostic capacities, as well as to understand parasite transmission cycles...
