Patient Willingness to Accept Hepatitis C-Infected Kidneys for Transplantation.

Background: As organs infected with Hepatitis C virus (HCV) provide an opportunity to expand the donor pool, the primary aim of this study is to gauge patient willingness to accept a kidney from HCV-infected donors compared to other high-risk donors. Methods: An anonymous, electronic survey was sent to all active kidney transplant waitlist patients at a single large volume transplant center. Patients were asked to respond to three hypothetical organ offers from the following: 1) HCV-infected donor 2) Donor with active intravenous drug use and 3) Donor with longstanding diabetes and hypertension. Results: The survey was sent to 435 patients of which 125 responded (29% response rate). While 86 out of 125 patients (69%) were willing to accept an HCV-infected kidney, only a minority of respondents were willing to accept a kidney from other high-risk donors. In contrast to other studies, by multivariable logistic regression, age and race were not associated with willingness to accept an HCV-infected kidney. Conclusions: From a patient perspective, utilization of kidneys from HCV-infected donors to expand the donor pool appears to be an acceptable option.
Muscimol-induced inactivation of the anterior cingulate cortex does not impair trace fear conditioning in the rat

Previous studies suggest that trace conditioning depends on the anterior cingulate cortex (ACC). To examine the role of ACC in trace fear conditioning further, 48 rats were surgically prepared for infusion with saline or 62.5 or 125 µg/side muscimol to inactivate ACC reversibly prior to conditioning. A noise stimulus was followed by a 1 mA footshock, with or without a 10-second trace interval between these events in a conditioned suppression procedure. The trace-conditioned groups (10 seconds) showed less test suppression than the control-conditioned groups (0 seconds). Counter to prediction, there was no effect of muscimol infusion on suppression to the noise stimulus in the 10-second trace groups.
The Predicted Metabolic Function of the Gut Microbiota of Drosophila melanogaster

An important goal for many nutrition-based microbiome studies is to identify the metabolic function of microbes in complex microbial communities and its impact on host physiology. This research can be confounded by poorly-understood effects of community composition and host diet on the metabolic traits of individual taxa. Here, we investigated these multi-way interactions by constructing and analyzing metabolic models comprising every combination of five bacterial members of the Drosophila gut microbiome (from single taxa to the five-member community of Acetobacter and Lactobacillus species) under three nutrient regimes. We show that the metabolic function of Drosophila gut bacteria is dynamic, influenced by community composition and responsive to dietary modulation. Furthermore, we show that ecological interactions such as competition and mutualism identified from the growth patterns of gut bacteria are underlain by a diversity of metabolic interactions, and show that the bacteria tend to compete for amino acids and B vitamins more frequently than for carbon sources. Our results reveal that in addition to fermentation products such as acetate, intermediates of the tricarboxylic acid (TCA) cycle including 2-oxoglutarate and succinate are produced at high flux and cross-fed between bacterial taxa suggesting important roles for TCA cycle intermediates in modulating Drosophila gut microbe interactions and the potential to influence host traits. These metabolic models provide specific predictions of the patterns of ecological and metabolic interactions among gut bacteria under different nutrient regimes, with potentially important consequences for overall community metabolic function and nutritional interactions with the host. IMPORTANCE Drosophila is an important model for microbiome research partly because of the low complexity of its mostly culturable gut microbiota. Our current understanding of how Drosophila interacts with its gut microbes and how these interactions influence host traits derives almost entirely from empirical studies that focus on individual microbial taxa or classes of metabolites. These studies have failed to capture fully the complexity of metabolic interactions that occur between host and microbe. To overcome this limitation, we reconstructed and analyzed 31 metabolic models for every combination of the five principal bacterial taxa in the gut microbiome of Drosophila. This revealed that metabolic interactions between between Drosophila gut bacterial taxa are highly dynamic and influenced by co-occurring bacteria and nutrient availability. Our results generate testable hypothesis about among-microbe ecological interactions in the Drosophila gut and the diversity of metabolites available to influence host traits.
Shape Matters: The Application of Activity-Based In Vitro Bioassays and Chiral Profiling to the Pharmacological Evaluation of Synthetic Cannabinoid Receptor Agonists in Drug-Infused Papers Seized in Prisons.

Synthetic cannabinoid receptor agonists (SCRAs) elicit many of their psychoactive effects via type-1 human cannabinoid (CB1 ) receptors. Enantiomer pairs of eight tert-leucinate or valinate indole- and indazole-3-carboxamide SCRAs were synthesized and their CB1 potency and efficacy assessed using an in vitro β-arrestin recruitment assay in a HEK239T stable cell system. A chiral high-performance liquid chromatography method with photodiode array and/or quadrupole-time of flight mass spectrometry detection (HPLC-PDA and HPLC-PDA-QToF-MS) was applied to 177 SCRA infused paper samples seized in Scottish prisons between 2018 and 2020. In most samples, SCRAs were almost enantiopure (S)-enantiomer (>98% of total chromatographic peak area), although in some (n=18), 2 to 16% of the (R)-enantiomer was detected. (S)-enantiomers are consistently more potent than (R)-enantiomers and often more efficacious. The importance of SCRA-CB1 receptor interactions in the 'head' or 'linked group' moiety is demonstrated, with the conformation of the 'bulky' tert-leucinate group greatly affecting potency (by up to a factor of 374), significantly greater than the difference observed between valinate SCRA enantiomers. (S)-MDMB-4en-PINACA, (S)-4F-MDMB-BINACA and (S)-5F-MDMB-PICA are currently the most prevalent SCRAs in Scottish prisons and all have similar high potency (EC50 , 1-5 nM) and efficacy. Infused paper samples were compared using estimated intrinsic efficacy at the CB1 receptor (EIECB1 ) to evaluate samples with variable SCRA content. Given their similar potency and efficacy, any variation in CB1 -receptor mediated psychoactive effects are likely to derive from variation in dose, mode of use, pharmacokinetic differences and individual factors affecting the user, rather than differences in the specific SCRA present.
Brazil's Craniofacial Project: Different approaches on orofacial clefts and 22q11.2 deletion syndrome

This article reports the present situation of Brazilian health care in genetics for Orofacial Cleft (OFC) and 22q11.2 Deletions Syndrome (22q11.2 DS) based on research conducted by Brazil's Craniofacial Project (BCFP). Established in 2003, BCFP is a voluntary and cooperative network aiming to investigate the health care of people with these diseases and other craniofacial anomalies. The initiatives and research results are presented in four sections: (a) a comprehensive report of the Brazilian public health system in craniofacial genetics; (b) multicentric studies developed on OFC and 22q11.2 DS; (c) education strategies focused on addressing these conditions for both population and health‐care professionals; and (d) the nosology through the Brazilian Database on Craniofacial Anomalies (BDCA). Since 2006, BDCA uses a standardized method with detailed clinical data collection, which allows for conducting studies on nosology, genotype–phenotype correlations, and natural history; data can also contribute to public policies. Currently, the BDCA stores data on 1,724 individuals, including 1,351 (78.36%) who were primarily admitted due to OFC and 373 (21.63%) with clinical suspicion of 22q11.2 DS. Chromosomal abnormalities/genomic imbalances were represented by 92/213 (43.19%) individuals with syndromic OFC, including 43 with 22q11.2 DS, which indicates the need for chromosomal microarray analysis in this group. The nosologic diversity reinforces that monitoring clinical is the best strategy for etiological investigation. BCFP's methodology has introduced the possibility of increasing scientific knowledge and genetic diagnosis of OFC and 22q11.2 DS to in turn improve health care and policies for this group of diseases.
C-Terminal-Pro-Endothelin-1 Adds Incremental Prognostic Value for Risk Stratification After Ischemic Stroke

Background and Aims: Endothelins have shown to play a role in the pathophysiology of ischemic stroke. We aimed at evaluating the incremental prognostic value of C-terminal-pro-endothelin-1 (CT-pro-ET-1) in a well-described cohort of acute stroke patients. Methods: We performed serial measurements of CT-pro-ET-1 in 361 consecutively enrolled ischemic stroke patients and assessed functional outcome and mortality after 90 days. As we found peak levels of CT-pro-ET-1 and the most prominent association with mortality on day 1 after admission (n = 312), we focused on this time point for further outcome analyses. We calculated logistic regression and cox proportional hazards models to estimate the association of CT-pro-ET-1 with our outcome measures after adjusting for demographic and clinical risk factors. To evaluate the incremental value of CT-pro-ET-1, we calculated the area under the receiver operating characteristics (AUC) curve and the continuous net reclassification index (cNRI) comparing the model with and without the biomarker CT-pro-ET-1. Results: In the univariate analysis CT-pro-ET-1 with a peak on day 1 after admission was associated with unfavorable outcome with an OR of 1.32 (95% CI, 1.16–1.51, p < 0.001) and with mortality with a HR of 1.45 (95% CI, 1.29–1.63, p < 0.001). After adjusting, CT-pro-ET-1 remained an independent predictor of mortality with an adjusted HR of 1.50 (95% CI, 1.29–1.74, p < 0.001), but not for functional outcome. Adding CT-pro-ET-1 to the cox-regression model for mortality, the discriminatory accuracy improved from 0.89 (95% CI, 0.84–0.94) to 0.92 (95% CI, 0.88–0.96) p < 0.001, and the cNRI was 0.72 (95% CI, 0.17–1.13). Conclusion: CT-pro-ET-1 with a peak level on day 1 was an independent predictor of mortality adding incremental prognostic value beyond traditional risk factors.
Clinical Manifestations of Allergic Bronchopulmonary Aspergillosis without Major Features of Asthma Diagnosed by the New Criteria in Japan

Allergic bronchopulmonary aspergillosis (ABPA) is a severe form of asthma in which structural airway destruction occurs due to a hypersensitivity reaction to fungi. A 25-year-old man without any major features of asthma had lung infiltration with dilatation of the central bronchus, high-attenuation mucus with histological eosinophilic invasion, fungi detected on cultures, and positive Aspergillus-specific immunoglobulin E (IgE) and precipitating antibody of Aspergillus, with a significant elevation of blood eosinophils and slightly increased total IgE. He recovered rapidly with systemic corticosteroid therapy without recurrence over 1-year follow-up and an increased forced expiratory volume in one second, which supported the possibility of ABPA without any major features of asthma.
Significance of Discordant Results between Confirmatory Tests in Diagnosis of Primary Aldosteronism.

CONTEXT Current clinical guidelines recommend confirmation of positive result in at least one confirmatory test in the diagnosis of primary aldosteronism (PA). Clinical implication of multiple confirmatory tests has not been established, especially when patients show discordant results. OBJECTIVE The aim of the present study was to explore the role of two confirmatory tests in subtype diagnosis of PA. DESIGN Retrospective cross-sectional study. SETTING The study was conducted at two referral centers. PARTICIPANTS AND METHOD We identified 360 hypertensive patients who underwent both captopril challenge test (CCT) and saline infusion test (SIT) and exhibited at least one positive result. Among them, we studied 193 patients with PA whose data were available for subtype diagnosis based on adrenal vein sampling (AVS). MAIN OUTCOME MEASURE The prevalence of bilateral subtype on AVS according to the results of the confirmatory tests. RESULTS Of patients studied, 127 were positive for both CCT and SIT (double-positive), while 66 were positive for either CCT or SIT (single-positive) (n = 34 and n = 32, respectively). Altogether, 135 were diagnosed with bilateral subtype on AVS. The single-positive patients had milder clinical features of PA than the double-positive patients. The prevalence of bilateral subtype on AVS was significantly higher in the single-positive patients than in the double-positive patients. (63/66 [95.5%] vs. 72/127 [56.7%], P < 0.01). Several clinical parameters were different between CCT single-positive and SIT single-positive patients. CONCLUSION Patients with discordant results between CCT and SIT have a high probability of bilateral subtype of PA on AVS.
COVID-19 Hospitalization in Adults with Type 1 Diabetes: Results from the T1D Exchange Multi-Center Surveillance Study

Abstract Context Diabetes mellitus is associated with increased COVID-19 morbidity and mortality, but there is little data focusing on outcomes in people with type 1 diabetes. Objective The objective of this study was to analyze characteristics of adults with type 1 diabetes for associations with COVID-19 hospitalization. Design An observational multi-site cross-sectional study was performed. Diabetes providers answered a 33-item questionnaire regarding demographics, symptoms, and diabetes- and COVID-19-related care and outcomes. Descriptive statistics were used to describe the study population, and multivariate logistic regression models were used to analyze the relationship between HbA1c, age, and comorbidities and hospitalization. Setting Cases were submitted from 52 US sites between March and August 2020. Patients or Other Participants Adults over the age of 19 with type 1 diabetes and confirmed COVID-19 infection were included. Interventions None. Main Outcome Measures Hospitalization for COVID-19 infection. Results A total of 113 cases were analyzed. Fifty-eight patients were hospitalized, and five patients died. Patients who were hospitalized were more likely to be older, to identify as non-Hispanic Black, to use public insurance, or to have hypertension, and less likely to use continuous glucose monitoring or insulin pumps. Median HbA1c was 8.6% (70 mmol/mol) and was positively associated with hospitalization (OR 1.42, 95% CI 1.18-1.76), which persisted after adjustment for age, sex, race, and obesity. Conclusions Baseline glycemic control and access to care are important modifiable risk factors which need to be addressed to optimize care of people with type 1 diabetes during the worldwide COVID-19 pandemic.
Local and State Policy Action Taken in the United States to Address the Emergence of E-Cigarettes and Vaping: A Scoping Review of Literature

Introduction In response to rising rates of youth vaping and e-cigarette use, states and localities in the United States have adopted various tobacco control policies and have extended their utility to these emerging products. However, the extent to which these policies have been evaluated for their impact on youth use is unknown. Method Two databases (PubMed, Google Scholar) were searched for English language peer-reviewed articles pertaining to electronic cigarette policy evaluation between 2009 and 2020. Primary articles of interest were journal articles that evaluated an e-cigarette policy. Secondary articles of interest were journal articles that identified any e-cigarette policy action without a formal evaluation component, those that evaluated tobacco policy, or those that described e-cigarette behaviors and trends. Tertiary articles included gray literature that provided context for e-cigarette trends and additional policy identification. Results The final sample consisted of 12 relevant articles with an e-cigarette policy evaluation component and 62 relevant articles without such component, and 19 gray literature sources. Findings were synthesized based on policy type: product classification, age restrictions, smoke-free policies, flavor bans, sales restrictions, taxation, packaging, and advertising. Conclusion Policies that address access and use of e-cigarettes are common on the federal, state, and local level, are mostly reactionary, and mimic tobacco control efforts. Few policies have been formally evaluated for their effectiveness in reducing or preventing youth vaping. Strengthening the evidence base should be a priority for researchers going forward, given the potential of these policies to intervene on social and environmental conditions that affect youth initiation and uptake.
Counter‐Selection Method for Markerless Allelic Exchange in Bordetella bronchiseptica Based on sacB Gene From Bacillus subtilis

Bordetella bronchiseptica is a gram‐negative bacterium that causes respiratory tract infections. It is a natural pathogen of a wide variety of mammals, including some used as laboratory models. This makes B. bronchiseptica an ideal organism to study pathogen–host interactions in order to unveil molecular mechanisms behind pathogenic processes. Even though genetic engineering is an essential tool in this area, there are just a few reports about genome manipulation techniques in this organism. In this article we describe an allelic exchange protocol based on double crossover recombination facilitated by the Bacillus subtilis sacB gene that can be applied for partial or complete gene knockouts, single‐nucleotide mutations, or even introduction of coding sequences for transcriptional fusions. In contrast to previously employed techniques, this protocol renders genetically manipulated chromosomes without foreign DNA and enables the construction of successive genome manipulation using the same vector backbone. The entire procedure has been developed for fast and reliable manipulations with a total duration of 2 weeks. © 2020 Wiley Periodicals LLC.
What is the difference in ablation zone of multi-bipolar radiofrequency ablation between liver cirrhosis and normal liver background? – a prospective clinical study

Abstract Purpose To explore the differences in ablation zone between liver cirrhosis and normal liver background and investigate the effect of hepatic blood flow on ablation zone of RFA. Methods Between 2017 and 2019, 203 patients who had liver malignancies and underwent percutaneous RFA with Celon bipolar electrodes enrolled into this study. There were 90 patients had liver cirrhosis and 113 patients had normal liver background. They were 63 females and 140 males with average age of 59.0 ± 10.9 years old. Contrast-enhanced CT/MRI was used to evaluate the ablation zone in one month after RFA. The hepatic flow measurements on CDFI and CEUS were performed before RFA. Correlations between ablation zone versus hepatic flow were assessed using multiple linear regression analysis. Results The average ablation zone in cirrhotic liver was significantly larger than those in normal liver background with 3 cm tip of RF electrodes (length 3.5 ± 0.5 vs 3.1 ± 0.4 cm, p = 0.001; width 2.6 ± 0.3 vs 2.2 ± 0.3 cm, p < 0.001; thickness 2.5 ± 0.3 vs 2.0 ± 0.2 cm, p < 0.001). The similar result was found with three 4 cm tip of RF electrodes (width 3.6 ± 0.5 vs 3.1 ± 0.5 cm, p = 0.019; thickness 3.3 ± 0.5 vs 2.7 ± 0.5 cm, p = 0.002). The multiple linear regression analysis showed arrive time of hepatic vein and portal vein was statistically associated with ablation zone with 3 cm electrodes (p < 0.001, p = 0.001), but explained part of the variance (Adjusted R2=0.294, adjusted R2=0.212). Conclusion The ablation zones of RFA with multi-bipolar electrodes in liver cirrhosis were significantly larger than those in normal liver background, being up to 6 mm in thickness. The hepatic flow parameters partly contributed to the ablation zone.
ANCA-associated vasculitis patients treated in Polish intensive care units – retrospective characteristics based on the POLVAS registry

Background ANCA-associated vasculitides (AAV) is a group of rare disorders where inflammation and damage of the small blood vessels lead to dysfunction of the supplied organs. In severe flares of the disease patients may require intensive care unit (ICU) admission and treatment. The study aims to characterize Polish patients with AAV who were admitted to the ICU and compare them to the others. Methods An observational, retrospective study based on the POLVAS – registry of Polish adult patients with AAV was carried out. Patients admitted to the ICU (ICU group) were identified and compared with the patients who did not require ICU admission (non-ICU group). Characteristics and comparison between groups were made using standard statistic descriptive methods. Results 30 patients admitted to the ICU were identified among 573 cases included in the registry. All patients in the ICU group with available data were ANCA positive. The clinical manifestations related to the ICU admission were respiratory, renal and central nervous system involvement. The treatment regimen for remission induction was similar in both groups. Almost half of the patients in the ICU-group (48.3%) required dialysis, whereas in the non-ICU group it was 21.8% (P = 0.01). Infections were also more frequent in the ICU group (72.4% vs. 36.9% P < 0.001). The mortality rate among patients who needed ICU treatment was significantly higher when compared to the rest of the patients (53.6% vs. 7.8%; P < 0.001). Conclusions In the Polish AAV cohort one in twenty patients required ICU admission. This group was characterized by multiple organ involvement and high mortality.
Evaluation of various levels of sweet almond meal as a source of protein on the production variables and immune response of broiler chickens

Abstract This study was conducted to evaluate effects of a sweet almond meal (SAM) as a source of protein on performance and immune responses of broiler chickens. Treatments consisted of different levels of SAM (7%, 14%, 21% and 28% of diet) and control diet that was performed in a completely randomized design in 42 days. Body weight gain (BWG) and feed intake (FI) were recorded weekly. Carcass characteristics and blood variables were measured on the 42 day of age. Immune response to sheep red blood cell (SRBC) was assessed at d 35 and d 42 (7 days after each injection). White blood cell count was done at d 28. The results showed that chickens fed 28% of SAM had lowest FI during the experiment. During grower period and also whole period of experiment, BWG was highest in chickens that consumed 7% SAM. Feed conversion ratio (FCR) significantly increased in chickens fed 28% SAM compared to the other treatments during grower period and also whole period of the experiment. The relative weight of thigh and breast significantly decreased and the relative weight of GIT increased by increasing levels of SAM in the diet. The concentration of cholesterol and LDL significantly decreased in chickens that consumed SAM in the diet. However, the highest glucose and HDL concentration were observed in chickens fed 28% SAM in the diet. Treatments did not have a significant effect on the immune response of broilers (primary and secondary SRBC antibody titres, relative weights of spleen and bursa of fabricius and white blood cell count) (p > 0.05). The results of this study show that a diet supplemented with SAM at the level of 14%, due to the improved FCR and decreased blood cholesterol and LDL concentration, can be a good replacement for soybean meal in broiler chicken's nutrition.
