Pregnancy can be considered as an allogeneic transplant and preeclampsia can be seen as a failure of the acceptance mechanisms of this transplant as occurs in acute organ transplant rejection. Some genetic polymorphisms may be involved in its pathogenesis. Since the kidney is one of the organs mainly involved in preeclampsia, our study attempted to determine the frequencies of single nucleotide polymorphisms of DNA (SNP) in 3 genes (adenosine triphosphate-binding cassette sub-family B member 1 (ABCB1)/multi drug reactivity 1 (MDR1) gene, interleukin 10 gene and tumor necrosis factor α gene) which are targets of immunosuppressive therapies and related to acute renal rejection. The study was an observational, monocentric, case-control study. We enrolled 20 women with severe preeclampsia and 10 women age-matched with regular pregnancy. Continuous variables were compared by the Student’s t- test for independent variables or using the Mann-Whitney test depending on their distribution. We used Fisher test to compare categorical variables between cases and controls, while we used logistic regression model to evaluate which risk factor was associated with preeclampsia. Although there was no statistically significant difference between the two groups, we found different percentages of two of the polymorphisms considered (rs1045642 and rs2032582 in the gene ABCB1). Despite these results, our work may be helpful for future research to better understand the pathogenesis of preeclampsia.

Abstract Background There is contradicting evidence characterizing the difference in pathogens that cause hip and knee prosthetic joint infection (PJI). A possible difference in microbiology may inform choice in antibiotic etiology, prophylaxis, and empiric treatment. We sought to analyze a large cohort of PJIs to see whether there was a significant difference in pathogen between joints. Methods A retrospective cohort of hip and knee PJIs, from 2008 to 2016, were identified by ICD code and surgical codes. The PJI pathogen was identified from synovial or intra-articular tissue cultures. The Student’s t-test was used to compare continuous variables. Chi-square tests were used to compare the categorical variables to joint. Results 807 PJI cases were identified including 444 knees and 363 hips. There were no significant differences between hip and knee PJIs in age, sex, history of PJI, rheumatoid arthritis, Charlson comorbidity index and laterality. There was a higher frequency of diabetes in knee PJIs (25.3%) compared with hip PJIs (15.7%), P < 0.001. No significant difference was found in the prevalence of fungal, staphylococcal (including Staphylococcus aureus), streptococcal, or enterococcal pathogens between hip and knee PJIs. Conclusion In this single-center cohort, hip and knees PJIs are infected with similar pathogens. Multiple site studies are needed to characterize the microbiology of PJIs at a larger scale.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Obesity is a common and known risk factor for many cardiovascular diseases. Prior studies on chronic systolic heart failure have demonstrated that obesity is inversely associated with mortality, the so-called obesity paradox. Purpose  To study the phenomenon of obesity paradox in HFrEF hospitalizations Methods We queried January 2016 to December 2018 National Inpatient Sample (NIS) to identify adult (≥18 yrs) hospitalizations with a primary diagnosis of HFrEF. Patients with an associated diagnosis of obesity and higher BMI were also identified based on appropriate ICD-10 CM codes. We used the Chi-square test to evaluate the differences between binary or categorical variables, and Student’s t-test for continuous variables. Multivariate logistic regression was used in outcomes analysis to adjust for potential hospital and patient-level confounders. Results  We identified 639,944 weighted HFrEF hospitalizations across three years. Of which, 130,949 (20.4%) of them were associated with obesity. HFrEF with obesity hospitalizations were associated with younger age (mean age 62.0 vs 70.7 yrs; P &lt; 0.01), lesser CAD (55% vs 61%; P &lt; 0.01), higher rate of comorbidity (% of &gt;3 Elixhauser comorbidity score 99.2% vs 94.1%; P &lt; 0.01) and higher Medicaid primary payer (18.2% vs 12.7%, P &lt; 0.01). After adjusting for patient and hospital-level characteristics, we observe statistically significant difference in odds of in-hospital mortality when HFrEF with obesity hospitalizations was compared to HFrEF without obesity [Odds Ratio (OR): 1.1 (0.8 – 1.5); P = 0.52]. We observed statistically significant association with increased LOS [6.0 vs 5.3 days; P &lt; 0.01], increased total hospitalization charges [US$ 61524 vs 55677; P &lt; 0.01] and decreased coronary catheterizations [OR: 0.7 (0.5 – 0.9); P = 0.01] in HFrEF with obesity group compared to HFrEF without obesity. Conclusion In this retrospective cohort of hospitalized patients with HFrEF, higher BMI and obesity was not associated with in-hospital mortality. However, it was associated with longer LOS and higher total hospitalization charges. HFrEF with obesity hospitalizations are associated with lesser left coronary catheterizations. This may be explained by lesser burden of CAD in this patient population.

Abstract Background Differentiating true glioblastoma multiforme (GBM) from pseudoprogression (PsP) remains a challenge with current standard magnetic resonance imaging (MRI). The objective of this study was to explore whether patients’ absolute lymphocyte count (ALC) levels can be utilized to predict true tumor progression and PsP. Methods Patients were considered eligible for the study if they had 1) GBM diagnosis, 2) a series of blood cell counts and clinical follow-ups, and 3) tumor progression documented by both MRI and pathology. Data analysis results include descriptive statistics, median (IQR) for continuous variables and count (%) for categorical variables, p values from Wilcoxon rank sum test or Fisher’s exact test for comparison, respectively, and Kaplan-Meier analysis for overall survival (OS). OS was defined as the time from patients’ second surgery to their time of death or last follow up if patients were still alive. Results 78 patients were included in this study. The median age was 56 years. Median ALC dropped 34.5% from baseline 1400 cells/mm3 to 917 cells/mm3 after completion of radiation therapy (RT) and temozolomide (TMZ). All study patients had undergone surgical biopsy upon MRI-documented progression. 37 had true tumor progression (47.44%) and 41 had pseudoprogression (52.56%). ALC before RT/TMZ, post RT/TMZ and at the time of MRI-documented progression did not show significant difference between patients with true progression and PsP. Although not statistically significant, this study found that patients with true progression had worse OS compared to those with PsP (Hazard Ratio [HR] 1.44, 95% CI 0.86–2.43, P = 0.178). This study also found that patients with high ALC (dichotomized by median) post-radiation had longer OS. Conclusion Our results indicate that ALC level in GBM patients before or after treatment does not have predictive value for true disease progression or pseudoprogression. Patients with true progression had worse OS compared to those who had pseudoprogression. A larger sample size that includes CD4 cell counts may be needed to evaluate the PsP predictive value of peripheral blood biomarkers.

Abstract Introduction Burn camps provide a unique environment and activities for children that have experienced a burn-injury. Positive outcomes from attending burn camp include increased self-esteem, decreased feelings of isolation and a greater sense of self-confidence. In a 3-year retrospective review of camper evaluations from one of the largest and longest running week-long burn camps in the nation for ages 5–17, we aimed to assess if a child’s gender, age, TBSA or ethnicity affected the impact that burn camp had on a child. Methods A 3-year retrospective review of a Burn Camp’s camper evaluation forms was conducted for campers that attended burn camp between 2017–2019. Camp rosters were reviewed to determine the camper gender, age, TBSA and ethnicity. Camper self-evaluation forms completed at the end of each camp session were reviewed to record camper responses to questions regarding their opinions on the impact camp had on them as well as how camp will impact their lives once they return home. Categorical variables were summarized as frequency and percentage, and continuous variables were described as median and range. To check the relationship between two categorical variables, Chi-square test was used. To compare the continuous variable among groups, Kruskal-Wallis ANOVA was used. Statistical significance was declared based on a p value&lt; 0.5. Results Within 2017–2019, there were 413 camper records. Participants’ demographic characteristics are summarized in Table 1. There were 208 males (50.3%) and 205 females (49.6%). The median age of campers were 11.86, 12.44 and 12.45 for 2017–2019, with the range from 5.16 years to 17.96 years. The median TBSA were 20, 20 and 18 for 2017–2019, with the range from 0.08 to 90. Collectively there were 47.7% Hispanic (n= 197); 24.2% Whites (n=100); 13.1% Black (n= 54); 4.6% Asian (n=19) and 7.7% Other (n=32). There were 395 camper self-evaluation forms submitted. Results of three questions there we were interested in are summarized collectively in Table 2. 57% of campers responded, “Yes, Definitely” to the question “After going to this event, will you feel more comfortable being around your classmates or friends?” 54% responded, “ Yes, Definitely” to the question “Do you feel more confidents in sharing your burn story with others when returning home?” and 51% responded “Yes, Definitely” to “Did you learn anything that will help you when you return home?” Conclusions In analyzing the camper responses, there was no statistically significant difference in responses comparing gender, age, TBSA or ethnicity.

AbstractNeuroendocrine tumor (NET) is one of malignant cancer and is identified with high morbidity and mortality rates around the world. With indigent clinical outcomes, potential biomarkers for diagnosis, prognosis and drug target are crucial to explore. The aim of this study is to examine the gene expression module of NET and to identify potential diagnostic and prognostic biomarkers as well as to find out new drug target. The differentially expressed genes (DEGs) identified from GSE65286 dataset was used for pathway enrichment analyses and gene ontology (GO) enrichment analyses and protein - protein interaction (PPI) analysis and module analysis. Moreover, miRNAs and transcription factors (TFs) that regulated the up and down regulated genes were predicted. Furthermore, validation of hub genes was performed. Finally, molecular docking studies were performed. DEGs were identified, including 453 down regulated and 459 up regulated genes. Pathway and GO enrichment analysis revealed that DEGs were enriched in sucrose degradation, creatine biosynthesis, anion transport and modulation of chemical synaptic transmission. Important hub genes and target genes were identified through PPI network, modules, target gene - miRNA network and target gene - TF network. Finally, survival analyses, receiver operating characteristic (ROC) curve and RT-PCR validated the significant difference of ATP1A1, LGALS3, LDHA, SYK, VDR, OBSL1, KRT40, WWOX, NINL and PPP2R2B between metastatic NET and normal controls. In conclusion, the DEGs and hub genes with their regulatory elements identified in this study will help us understand the molecular mechanisms underlying NET and provide candidate targets for future research.

Background: Dysphagia is common after stroke and is associated with an increased risk for pulmonary complications and mortality. Current standards mandate screening for dysphagia before oral intake in all acute stroke patients. We aimed to show if this early screening affects long-term outcomes after stroke. Methods: We included all UCSD Medical Center discharges with diagnosis AIS, ICH and SAH between July 1 2008 and June 30 2011; and evaluated baseline demographics, admission diagnosis (AIS, ICH, SAH), admission source (ED or transfer) length of hospital stay (LOS), ICU-LOS, aspiration pneumonia, in-hospital, 30-day and 6-month mortality by public death records for all patients. Patients were grouped as: 1) no dysphagia screening performed, 2) Nil per os (NPO) until discharge, 3) dysphagia screening performed. Adjustments for stroke severity and CMI were not possible. Statistical comparisons were done with the Kruskal-Wallis test (continuous variables) or Fisher-Freeman-Halton test (categorical variables). For pairwise comparisons we used the Wilcoxon tests (continuous variables) or Fisher’s Exact test (categorical variables), with Holm’s adjusted p-values. Results: A total of 476 patients were included, Group 1: 47, Group 2: 119, Group 3: 310. There was no significant difference in age, gender, race/ethnicity, and diagnosis of HTN, DM, afib, prior stroke and admission source. More patients with SAH and ICH were in Group 2. Overall, LOS and ICU LOS, aspiration pneumonia, in-hospital, 30-day and 6-month mortality were found to be different among groups (p<0.0001). Pair-wise comparisons showed that all outcomes were significantly higher in Group 2, but similar between Groups 1 and 3 (NS). Conclusion: We found no difference in outcomes between patients who received dysphagia screening versus not (Group 1 vs 3). Excluding patients who were left NPO and are more likely to suffer from ICH, SAH with increased morbidity and mortality, it remains uncertain if a targeted early dysphagia screening can reduce morbidity and mortality after stroke. Further studies are needed to find the appropriate population that most benefits from dysphagia screening.

Introduction: The objective of this prospective study was to examine whether thromboelastogram (TEG) can predict the presence of venous thromboembolism (VTE) in patients who arrive at the emergency room with signs/symptoms that raise the suspicion of acute VTE. Methods: Every patient was tested for D-dimer and all TEG parameters, including: reaction time, clot time formation, alpha-angle, maximal amplitude, clot viscoelasticity, coagulation index, and clot lysis at 30 min. For categorical variables, χ2 or the Fisher exact test were used, and for continuous variables the t test or other non-parametric tests were used. Results: During 2016, a total of 109 patients were enrolled with a median age of 55.7 (21–89) years. Eighteen patients were diagnosed with VTE. Analyzing the different TEG parameters, both as continuous and categorical variables, did not reveal a statistically significant difference between VTE-positive and VTE-negative patients. Combining different TEG parameters or dividing the cohort according to gender, clinical suspicion of VTE (Well’s criteria), or different levels of D-dimer did not change the results of the analysis. Conclusion: The current study could not demonstrate a significant value of any TEG parameter as a predictor of VTE among patients who came to the emergency room with signs/symptoms that raise the suspicion of VTE.

Objective To investigate the association between single nucleotide polymorphisms (SNPs) in six candidate genes (enamelin [ ENAM]; tuftelin 1 [ TUFT1]; matrix metallopeptidase 13 [ MMP13]; interleukin 1 beta [ IL1B]; interleukin 10 [ IL10]; interleukin 1 receptor antagonist [ IL1RN]) and dental caries in children from northwest China. Methods This case–control study enrolled children (12–15 years) who underwent routine dental examinations. The children were divided into two groups based on the presence of dental caries. A saliva sample was collected and seven SNPs (rs3806804A/G in ENAM, rs3811411T/G in TUFT1, rs2252070A/G and rs597315A/T in MMP13, rs1143627C/T in IL1B, rs1800872A/C in IL10 and rs956730G/A in IL1RN) were genotyped. Results A total of 357 children were enrolled in the study: 161 with dental caries and 196 without dental caries. No significant difference was found in the alleles and genotypes of five genes ( ENAM, TUFT1, MMP13, IL10 and IL1RN) between those with and without dental caries. A significant relationship was found between the IL1B rs1143627C/T polymorphism and dental caries susceptibility with those carrying the rs1143627CT genotype having a lower risk of dental caries compared with those carrying the CC genotype (odds ratio 0.557; 95% confidence interval 0.326, 0.952). Conclusion The IL1B rs1143627C/T polymorphism may be associated with dental caries susceptibility in children from northwest China.

Abstract Background and purpose From the various mechanical cardiac assist devices and indications available, use of the percutaneous intraventricular Impella CP pump is usually restricted to acute ischemic shock or prophylactic indications in high-risk interventions. In the present study, we investigated clinical usefulness of the Impella CP device in patients with non-ischemic cardiogenic shock as compared to acute ischemia. Methods In this retrospective single-center analysis, patients who received an Impella CP between 2013 and 2017 due to non-ischemic cardiogenic shock were age-matched 2:1 with patients receiving the device due to ischemic cardiogenic shock. Inclusion criteria were therapy refractory hemodynamic instability with severe left ventricular systolic dysfunction and serum lactate >2.0 mmol/l at implantation. Basic clinical data, indications for mechanical ventricular support, and outcome were obtained in all patients with non-ischemic as well as ischemic shock and compared between both groups. Continuous variables are expressed as mean ± standard deviation or median (quartiles). Categorical variables are presented as count and percent. Results 25 patients had cardiogenic shock due to non-ischemic reasons, and were compared to 50 patients with cardiogenic shock due to acute myocardial infarction. Resuscitation rates before implantation of Impella CP were high (32 vs 42%; P=0.402). At implantation, patients with non-ischemic cardiogenic shock had lower levels of HsTNT (110.65 [57.87–322.1] vs 1610 [450.8–3861.5] pg/ml; P=0.001) and LDH (377 [279–608] vs 616 [371.3–1109] U/I; P=0.007), while age (59±16 vs 61.7±11; P=0.401), GFR (43.5 [33.2–59.7] vs 48 [35.75–69] ml/min; P=0.290), CRP (5.17 [3.27–10.26] vs 10.97 [3.23–17.2] mg/dl; P=0.195), catecholamine-index (30.6 [10.6–116.9] vs 47.6 [11.7–90] μg/kg/min; P=0.663), and serum lactate (2.6 [2.2–5.8] vs 2.9 [1.3–6.6] mg/dl; P=0.424) were comparable between both groups. There was a trend for longer duration of Impella support in the non-ischemic groups (5 [2–7.5] vs 3 [2–5.25] days, P=0.211). Rates of hemodialysis (52 vs 47%; P=0.680) and transition to ECMO (13.6 vs 22.2%; P=0.521) were comparable. No significant difference was found regarding both 30-days survival (48 vs 30%; P=0.126, Figure 1) as well in-hospital mortality (66.7 vs 74%; P=0.512) although there was a trend for better survival in the non-ischemic group. 30-days survival Conclusions The current results position short-time use of the Impella CP as an alternative in the treatment of patients with cardiogenic shock due to underlying non-ischemic cardiomyopathy and/or complicating additional factors. However, additional studies are needed to test whether these findings can be confirmed in larger patient populations and which subgroups might benefit most from Impella therapy.

Introduction: Intracerebral bleeds are the second most common cause of stroke. The initial consciousness level and progressive deterioration and various radiological parameters like hematoma volume, its expansion, mass effect and location has been implicated with poor outcomes of Intracerebral Hematoma (ICH) regardless of the management methods. In this study we aimed to study various clinical and radiological parameters associated with outcome of spontaneous supratentorial ICH. Methods: This prospective study was carried out in 89 patients of spontaneous supratentorial ICH admitted to National Institute of Neurological and Allied Sciences, Nepal in between January 2015 to December 2015 to assess various parameters associated with its outcome. Outcome of the patients were assessed against various clinic-radiological and demographic variables using chi square test and student’s t test respectively for categorical and continuous variables using IBM SPSS 20 software. Results: Glasgow Coma Scale (GCS) (p=0.00), size of hematoma (p=0.034), presence of midline shift (0.000) and presence of intraventricular hematoma (p=0.020) were found to have statistically significant difference when compared in between good and poor outcome group. Conclusion: GCS at admission, size of hematoma, midline shift in cerebral tomography scan (CT scan) and presence of intraventricular hemorrhage (IVH) were significantly associated with outcome of spontaneous Supratentorial ICH.
