Cardiovascular diseases in congenital prekallikrein deficiency: comparison with other chance-associated morbidities

&NA; To compare the prevalence of cardiovascular diseases with other chance-associated morbidities in patients with congenital prekallikrein deficiency. Patients with prekallikrein deficiency were gathered from two time unlimited PubMed searches and from personal files. Inclusion criteria were prekallikrein level less than 15% of normal; correction of aPTT on long incubation times; prolonged aPTT corrected by normal plasma or serum; normal prothrombin time and normal FXII and FXI. Acquired forms were excluded. Out of 106 patients, we have found that 45 patients had at least one chance-associated defect or morbidity at the time of the diagnosis of the clotting defect. Twenty-nine of these 45 patients had cardiovascular disorders. Other comorbidities were found in a much smaller proportion. Congenital prekallikrein deficiency is frequently associated with cardiovascular conditions, namely hypertension, coronary disease, ischemic stroke, venous thrombosis. The significance of these findings is critically discussed as association between two diseases does not necessarily indicate the existence of a causative relation between the two. However, the findings presented here clearly indicate the possibility that such a relation might indeed exist.
On the K‐sat model with large number of clauses

We show that in the K‐sat model with N variables and αN clauses, the expected ratio of the smallest number of unsatisfied clauses to the number of variables is α/2K−αc∗(N)/2K up to smaller order terms o(α) as α→∞ uniformly in N, where c∗(N) is the expected normalized maximum energy of some specific mixed p‐spin spin glass model. The formula for the limit of c∗(N) is well known in the theory of spin glasses.
Histological predictors of renal outcome in lupus nephritis: the importance of tubulointerstitial lesions and scoring of glomerular lesions

Introduction Lupus nephritis (LN) affects nearly 60% of patients with systemic lupus erythematosus and up to 30% of them will progress to end-stage renal disease (ESRD), despite receiving aggressive immunosuppressive therapy. The prognostic value of ISN/RPS classification is controversial. Therefore, we aimed to identify clinical and pathological predictors of outcome in LN patients independent of this classification. Material and methods Thirty-seven patients with LN who underwent percutaneous kidney biopsy between 1997 and 2016 were included in this study. Twenty clinical and twenty histological variables were tested for their association with a composite end-point of doubling of serum creatinine, ESRD and death. Univariate and multivariate Cox proportional hazard regression analysis were performed to identify independent predictors of outcome. Results During a median follow-up period of 48 months (IQR: 17.5–120 months), 21.6% of patients reached the composite end-point. The overall survival rate of our cohort was 89% at one year, 86% at five years, 74% at 10 years and 64% at 20 years. Patients with Class IV LN showed the worst prognosis with 44% survival at 10 years, while those who additionally showed crescents and global sclerosis on kidney biopsy had an even lower survival of 21% and 0% at 10 years, respectively. After multivariate adjustment, we identified estimated glomerular filtration rate at baseline (HR, 0.91 per ml/min /1.73 m2; 95% CI, 0.84 to 0.99), 24-hour proteinuria at baseline (HR, 2.04 per g/d; 95% CI, 1.19 to 3.5), crescents (HR, 1.068 per %; 95% CI, 1.003 to 1.091), global sclerosis (HR, 1.036 per %; 95% CI, 0.984 to 1.091), presence of adhesions (HR, 9.2; 95% CI, 1.38 to 61.2) and tubulitis (HR, 13.1; 95% CI; 1.3 to 131) as independent predictors of outcome in our cohort of LN. Conclusions Our study identified glomerular (crescents, global sclerosis, adhesions) and tubulointerstitial (tubulitis) lesions, in addition to clinical variables (renal function, 24-hour proteinuria), as important predictors of renal outcome, independent of the ISN/RPS classification. We suggest that the ISN/RPS classification could be improved by a quantitative assessment of glomeruli with active and chronic lesions and by a greater emphasis given to tubulointerstitial lesions.
Enhancements to SAT Attack

Logic encryption is an IC protection technique for preventing an IC design from overproduction and unauthorized use. It hides a design’s functionality by inserting key gates and key inputs, such that a secret key is required to activate the design and make it functioncorrectly. The security of a logic encryption algorithm is evaluated according to the difficulty of cracking the secret key. The state-of-the-art attack method identifies a secret key with a series of SAT-solving calls to prune all the incorrect keys. Although it can break most of the existing logic encryption algorithms within a few hours, we observe that there exist two enhancements for increasing its efficiency. First, we introduce a preprocess to identify and eliminate redundant key inputs and simplify SAT problems. Second, we present a key checking process for increasing the pruned incorrect keys in each SAT-solving iteration. We conducted the experiments on a set of benchmark circuits encrypted by six different logic encryption algorithms. The simulation results show that the enhanced method can successfully unlock 10 benchmark circuits which originally could not be cracked within 1 hour. For all the benchmark circuits, the average speedup is approximately 2.2x in terms of simulation time. Furthermore, a recent logic encryption method locks a design by creating cyclic paths, which can invalidate the SAT-based attack method. We analyze the impact of cyclic paths and propose an enhancement to break the cyclic logic encryption method.
Association between comorbid cancer and outcomes among admissions for acute ischemic stroke receiving systemic thrombolysis

Background The impact of cancer on outcomes was not assessed in major trials of systemic thrombolysis in acute ischemic stroke. Aims To evaluate the association between comorbid cancer and hospital outcomes among patients receiving systemic thrombolysis for the treatment of acute ischemic stroke. Methods The 2013 and 2014 United States National Inpatient Sample was used to identify adult patients hospitalized for acute ischemic stroke who received systemic thrombolysis. Identified admissions were stratified into two cohorts based on the presence or absence of comorbid cancer. Multivariable logistic regression was performed to determine the association between comorbid cancer and the odds of in-hospital mortality and intracerebral hemorrhage after adjustment for age ≥75 years and comorbid atrial fibrillation. Results A total of 13,993 acute ischemic stroke admissions were treated with systemic thrombolysis. Of these, 3.0% (n = 416) had comorbid cancer. The overall incidence of in-hospital mortality was 7.0% and intracerebral hemorrhage occurred in 7.6% of patients. Upon multivariable adjustment, comorbid cancer was not associated with an increased odds of in-hospital mortality (odds ratio = 1.24; 95% confidence interval = 0.88–1.76). However, the adjusted odds of intracerebral hemorrhage were higher among those with comorbid cancer (odds ratio = 1.60; 95% confidence interval = 1.17–2.17). Conclusions In this retrospective study of admissions for acute ischemic stroke receiving thrombolysis, comorbid cancer was not associated with a higher odds of in-hospital mortality but was associated with an increased odds of intracerebral hemorrhage. Factors driving this observed association should be explored in data sets containing clinical variables.
A general class of nonparametric control charts

In this article, we introduce a new general class of nonparametric Shewhart‐type control charts using the lengths of runs of test sample observations between successive observations of a reference sample. Several control charts that have appeared in the literature are members of the new family. In addition, 3 new nonparametric control charts that belong to the class are introduced and studied. Numerical results depict that the proposed charts attain competitive in‐control and out‐of‐control performance as compared with existing nonparametric charts.
The Gap Game

Blockchain-based cryptocurrencies secure a decentralized consensus protocol by incentives. The protocol participants, called miners, generate (mine) a series of blocks, each containing monetary transactions created by system users. As incentive for participation, miners receive newly minted currency and transaction fees paid by transaction creators. Blockchain bandwidth limits lead users to pay increasing fees in order to prioritize their transactions. However, most prior work focused on models where fees are negligible. In a notable exception, Carlsten et al. [17] postulated that if incentives come only from fees then a mining gap would form~--- miners would avoid mining when the available fees are insufficient. In this work, we analyze cryptocurrency security in realistic settings, taking into account all elements of expenses and rewards. To study when gaps form, we analyze the system as a game we call the gap game. We analyze the game with a combination of symbolic and numeric analysis tools in a wide range of scenarios. Our analysis confirms Carlsten et al.'s postulate; indeed, we show that gaps form well before fees are the only incentive, and analyze the implications on security. Perhaps surprisingly, we show that different miners choose different gap sizes to optimize their utility, even when their operating costs are identical. Alarmingly, we see that the system incentivizes large miner coalitions, reducing system decentralization. We describe the required conditions to avoid the incentive misalignment, providing guidelines for future cryptocurrency design.
Congenital Zika syndrome: Pitfalls in the placental barrier

Much progress with respect to congenital Zika virus (ZIKV) pathogenesis has been achieved after the 2015 outbreak in Brazil. It is now accepted that ZIKV is vertically transmitted, infects cells of the developing central nervous system and the placenta, yet it is unclear to what extent placental affection contributes to the development of congenital ZIKV. The association between fulminant villitis and severe fetal involvement emerges as a possibility. ZIKV is unique among the Flaviviruses in its ability to be sexually transmitted, possibly responsible for its teratogenicity. Furthermore, there is controversy over the participation of antibody dependent enhancement (ADE) in patients with non‐neutralizing anti‐Flavivirus antibodies, a phenomenon previously recognized in serious DENV infections. Our aim was to analyze information regarding the contribution of the placental barrier as an actual player in neonatal ZIKV. Therefore, we underwent a systematic review with keywords “Zika virus” and “ZIKV”. Articles were screened for relevance concerning the topics of microcephaly, transplacental transmission, sexual transmission, and ADE. We identified variables that affect the severity of congenital Zika syndrome: age of gestation at maternal infection, the extent of placental disruption (villitis), sexual transmission, initial viral replication at the uterine wall, anti‐DENV antibodies, and the possibility of antibody‐mediated transcytosis of ZIKV through the placenta. These questions may not seem relevant when Zika becomes endemic, and we are no longer witness to the extreme clinical sequelae seen when the virus moves through an immunologically naïve population; however, characterizing the pathogenesis of congenital Zika syndrome will continue to further our understanding.
Effectiveness and Safety of Dietetic Supplementation of a New Nutraceutical on Lipid Profile and Serum Inflammation Biomarkers in Hypercholesterolemic Patients

Background: To assess the effectiveness and safety of a new nutraceutical (NC) on lipid profile, inflammation biomarkers and creatine phosphokinase (CPK) serum levels in hypercholesterolemic patients. Methods: 40 patients underwent hypolipemic treatment with NC. Initial and final (after 12 weeks) screening included medical history, physical examination, and measurement of serum lipid profile (total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglycerides), hepatic (GOT, GPT, γGT), and renal (serum creatinine and urea) functions, CPK level and many inflammation biomarkers (hs-CRP and fibrinogen). At the screening visit, all patients were instructed to follow a normocaloric and hypolipidic diet during the study period. Results: The treatment with supplementation of NC demonstrated a significant reduction of serum total cholesterol (224 ± 11.2 mg/dL vs. 178 ± 10.7; p < 0.001), LDL-cholesterol (141 ± 10.6 vs. 116 + 10.1; p < 0.001), triglycerides (183 ± 13 vs. 159 ± 11.5; p < 0.01), serum inflammatory biomarkers as hs-CRP (2.24 ± 0.83 vs. 1.76 ± 0.61 mg/dL; p < 0.01), fibrinogen (315 ± 43 vs. 199 ± 41 mg/dL; p < 0.01) and a significantly increase of HDL-cholesterol (44 ± 7 vs. 53 ± 7 mg/dL; p < 0.01). Hepatic and renal function and serum CPK were normal. No adverse events was reported. Conclusions: The treatment with NC has demonstrated a significant reduction of LDL-cholesterol (−17.73%), total cholesterol (−20.53%) and triglycerides (−13.1%), with a significant increase of HDL-cholesterol values (+20.45%). The improvement of lipid profile was associated with a significant reduction of serum inflammation biomarkers as hs-PCR (−27%) and fibrinogen (−36.8%) with good tolerability profile.
Comprehensive nationwide analysis of mother-to-child HIV transmission in Finland from 1983 to 2013

Abstract HIV-positive children are still born in Europe despite low mother-to-child transmission (MTCT) rates. We aimed to clarify the remaining barriers to the prevention of MTCT. By combining the national registers, we identified all women living with HIV delivering at least one child during 1983–2013. Of the 212 women delivering after HIV diagnosis, 46% were diagnosed during the pregnancy. In multivariate analysis, age >30 years (P = 0.001), sexual transmission (P = 0.012), living outside of the metropolitan area (P = 0.001) and Eastern European origin (P = 0.043) were risk factors for missed diagnosis before pregnancy. The proportion of immigrants increased from 18% before 1999 to 75% during 2011–2013 (P < 0.001). They were diagnosed during the pregnancy equally to natives and achieved similar, good treatment results. No MTCT occurred when the mother was diagnosed before the delivery. In addition, 12 women had delivered in 2 years prior their HIV diagnosis, most before implementation of the national screening of pregnant women. Three of these children were infected, the last one in 2000. Our data demonstrate that complete elimination of MTCT is feasible in a high-income, low-prevalence country. This requires ongoing universal screening in early pregnancy and easy access to antiretroviral therapy to all HIV-positive people.
microRNA‐665 promotes the proliferation and matrix degradation of nucleus pulposus through targeting GDF5 in intervertebral disc degeneration

Growing evidences suggested that microRNAs (miRNAs) played important roles in the development of intervertebral disc degeneration (IDD). However, the expression level and function of miR‐665 in IDD remain unknown. In this study, we showed that the expression level of miR‐665 was upregulated in degenerative human NP samples. In addition, miR‐665 expression level gradually increased with the exacerbation of disc degeneration grade. Moreover, miR‐665 expression level was positively associated with the Pfirrmann grade. Ectopic expression of miR‐665 promoted NP cell growth. Furthermore, miR‐665 overexpression decreased aggrecan and Col II expression and ectopic expression of miR‐665 increased MMP‐3 and MMP‐13 expression in NP cell. We identified growth differentiation factor 5 (GDF5) was a direct target gene of miR‐665 in NP cell and enforced expression of miR‐665 decreased GDF5 expression. Elevated expression of miR‐665 enhanced NP cell proliferation and decreased aggrecan and Col II expression. In addition, ectopic expression of miR‐665 increased MMP‐3 and MMP‐13 expression through inhibiting GDF5 expression in NP cells. These results suggested that dysregulated miR‐665 expression might act an important role in the development of IDD.
Object Specific Deep Feature for Face Detection

Motivated by the observation that certain convolutional channels of a Convolutional Neural Network (CNN) exhibit object specific responses, we seek to discover and exploit the convolutional channels of a CNN in which neurons are activated by the presence of specific objects in the input image. A method for explicitly fine-tuning a pre-trained CNN to induce object specific channel (OSC) and systematically identifying it for the human faces has been developed. In this paper, we introduce a multi-scale approach to constructing robust face heatmaps based on OSC features for rapidly filtering out non-face regions thus significantly improving search efficiency for face detection. We show that multi-scale OSC can be used to develop simple and compact face detectors in unconstrained settings with state of the art performance. key words: deep feature, convolutional neural network, object specific channel, face detection
Comparison of the Incorporation of DHA in Circulatory and Neural Tissue When Provided as Triacylglycerol (TAG), Monoacylglycerol (MAG) or Phospholipids (PL) Provides New Insight into Fatty Acid Bioavailability

Phospholipids (PL) or partial acylglycerols such as sn-1(3)-monoacylglycerol (MAG) are potent dietary carriers of long-chain polyunsaturated fatty acids (LC-PUFA) and have been reported to provide superior bioavailability when compared to conventional triacylglycerol (TAG). The main objective of the present study was to compare the incorporation of docosahexaenoic acid (DHA) in plasma, erythrocytes, retina and brain tissues in adult rats when provided as PL (PL-DHA) and MAG (MAG-DHA). Conventional dietary DHA oil containing TAG (TAG-DHA) as well as control chow diet were used to evaluate the potency of the two alternative DHA carriers over a 60-day feeding period. Fatty acid profiles were determined in erythrocytes and plasma lipids at time 0, 7, 14, 28, 35 and 49 days of the experimental period and in retina, cortex, hypothalamus, and hippocampus at 60 days. The assessment of the longitudinal evolution of DHA in erythrocyte and plasma lipids suggest that PL-DHA and MAG-DHA are efficient carriers of dietary DHA when compared to conventional DHA oil (TAG-DHA). Under these experimental conditions, both PL-DHA and MAG-DHA led to higher incorporations of DHA erythrocytes lipids compared to TAG-DHA group. After 60 days of supplementation, statistically significant increase in DHA level incorporated in neural tissues analyzed were observed in the DHA groups compared with the control. The mechanism explaining hypothetically the difference observed in circulatory lipids is discussed.
PIEZO1 Channel Is a Potential Regulator of Synovial Sarcoma Cell-Viability

Detection of mechanical stress is essential for diverse biological functions including touch, audition, and maintenance of vascular myogenic tone. PIEZO1, a mechano-sensing cation channel, is widely expressed in neuronal and non-neuronal cells and is expected to be involved in important biological functions. Here, we examined the possibility that PIEZO1 is involved in the regulation of synovial sarcoma cell-viability. Application of a PIEZO1 agonist Yoda1 effectively induced Ca2+ response and cation channel currents in PIEZO1-expressing HEK (HEK-Piezo1) cells and synovial sarcoma SW982 (SW982) cells. Mechanical stress, as well as Yoda1, induced the activity of an identical channel of conductance with 21.6 pS in HEK-Piezo1 cells. In contrast, Yoda1 up to 10 μM had no effects on membrane currents in HEK cells without transfecting PIEZO1. A knockdown of PIEZO1 with siRNA in SW982 cells abolished Yoda1-induced Ca2+ response and significantly reduced cell cell-viability. Because PIEZO1 is highly expressed in SW982 cells and its knockdown affects cell-viability, this gene is a potential target against synovial sarcoma.
Dietary taste patterns by sex and weight status in the Netherlands

Abstract Taste is a key driver of food choice and intake. Taste preferences are widely studied, unlike the diet’s taste profile. This study assessed dietary taste patterns in the Netherlands by sex, BMI, age and education. A taste database, containing 476 foods’ taste values, was combined with 2-d 24-h recalls in two study populations. The percentage of energy intake from six taste clusters was assessed in the Dutch National Food Consumption Survey (DNFCS 2007–2010; n 1351) and in an independent observational study: the Nutrition Questionnaires plus (NQplus) study (2011–2013; n 944). Dietary taste patterns were similar across study populations. Men consumed relatively more energy from ‘salt, umami and fat’ (DNFCS; 24 % energy, NQplus study; 23 %)- and ‘bitter’ (7 %)-tasting foods compared with women (21 %, P<0·001, 22 %, P=0·005; 3 %, P<0·001, 4 %, P<0·001, respectively). Women consumed more % energy from ‘sweet and fat’ (15 %)- and ‘sweet and sour’ (13 %, 12 %, respectively)-tasting foods compared with men (12 %, P<0·001, 13 %, P=0·001; 10 %, P<0·001). Obese individuals consumed more % energy from ‘salt, umami and fat’- and less from ‘sweet and fat’-tasting foods than normal-weight individuals (‘salt, umami and fat’, men; obese both studies 26 %, normal-weight DNFCS 23 %, P=0·037, NQplus 22 %, P=0·001, women; obese 23 %, 24 %, normal weight 20 %, P=0·004, P=0·011, respectively, ‘sweet and fat’, men; obese 11 %, 10 %, normal weight 13 %, P<0·05, 14 %, P<0·01, women; obese 14 %, 15 %, normal weight 16 %, P=0·12, P=0·99). In conclusion, our taste database can be used to deepen our understanding of the role of taste in dietary intake in the Netherlands by sex, BMI, age and education.
Self-efficacy Predicts Success in an Exercise Training-Only Model of Pulmonary Rehabilitation for People With COPD

Purpose: To determine whether people with chronic obstructive pulmonary disease (COPD) have characteristics that predict a clinically meaningful response to pulmonary rehabilitation (PR) that includes an education component compared with exercise training alone. Methods: Participants were classified as responders or nonresponders to 2 models of PR; exercise training and education (ET + ED, n = 113) or exercise training alone (ET, n = 85). Responders were defined as those who achieved a clinically meaningful change in 6-min walk distance (6MWD) or any of the 4 domains of the Chronic Respiratory Questionnaire (CRQ). Baseline characteristics were compared between responders and nonresponders. The associations between baseline data and change in 6MWD and CRQ following PR were examined, and a binary logistic regression analysis was conducted for each model and primary outcome. Results: There were no significant differences between the PR models in proportion of responders (ET + ED 92% vs ET 93%). Lower baseline CRQ scores predicted response in respective CRQ domains for fatigue, emotion, and mastery in the ET + ED group, and for dyspnea, fatigue, and mastery in the ET group. Higher baseline self-efficacy predicted 6MWD response and higher socioeconomic status predicted response in CRQ fatigue in the ET model only. There was no predictor of 6MWD response in the ET + ED group. Conclusions: Baseline characteristics did not reliably predict a clinically meaningful response to PR that included education. For exercise training alone, higher self-efficacy was a significant predictor for greater improvements in 6MWD, suggesting that those with higher confidence should be considered for this model.
