Faithful performance prediction of a dynamic task‐based runtime system for heterogeneous multi‐core architectures

Multi‐core architectures comprising several graphics processing units (GPUs) have become mainstream in the field of high‐performance computing. However, obtaining the maximum performance of such heterogeneous machines is challenging as it requires to carefully off‐load computations and manage data movements between the different processing units. The most promising and successful approaches so far build on task‐based runtimes that abstract the machine and rely on opportunistic scheduling algorithms. As a consequence, the problem gets shifted to choosing the task granularity, task graph structure, and optimizing the scheduling strategies. Trying different combinations of these different alternatives is also itself a challenge. Indeed, obtaining accurate measurements requires reserving the target system for the whole duration of experiments. Furthermore, observations are limited to the few available systems at hand and may be difficult to generalize. In this article, we show how we crafted a coarse‐grain hybrid simulation/emulation of StarPU, a dynamic runtime for hybrid architectures, over SimGrid, a versatile simulator of distributed systems. This approach allows to obtain performance predictions of classical dense linear algebra kernels accurate within a few percents and in a matter of seconds, which allows both runtime and application designers to quickly decide which optimization to enable or whether it is worth investing in higher‐end graphics processing units or not. Additionally, it allows to conduct robust and extensive scheduling studies in a controlled environment whose characteristics are very close to real platforms while having reproducible behavior.

Cheese and Cardiovascular Disease Risk: A Review of the Evidence and Discussion of Possible Mechanisms

Currently, the effect of dairy products on cardiovascular risk is a topic much debated and with conflicting results. The purpose of this review is to give an overview of the existing literature regarding the effect of cheese intake and risk of cardiovascular disease (CVD). Studies included reporting the intake of cheese and risk of CVD or risk markers of CVD represent four human intervention studies, nine prospective studies, one prospective case-cohort study, one prospective nested case-control study, five case-control studies, five cross-sectional studies and three correlation studies. The possible mechanisms that may be of importance include calcium, protein, fermentation and the fatty acid composition of cheese. Results from four prospective studies reported no association between cheese intake and CVD risk, whereas one reported an increased risk, two reported a decreased risk and one reported no association in men but a decreased risk in women. In addition, results from four intervention studies indicated no harmful effect on cholesterol concentrations when comparing fat intake from cheese with fat from butter. The underlying mechanisms for these findings still need to be elucidated.
Population pharmacokinetics of pregabalin in healthy subjects and patients with chronic pain or partial seizures

Purpose: Pregabalin, a high‐affinity ligand for α2δ subunits of voltage‐gated calcium channels, is a novel pharmacotherapy for chronic pain, partial seizures, and other disorders. The present study investigated the population pharmacokinetics of pregabalin following single and multiple doses in healthy volunteers and patient populations.
Worldwide Status of Fresh Fruits Irradiation and Concerns about Quality, Safety, and Consumer Acceptance

ABSTRACT Development of knowledge-based food preservation techniques have been a major focus of researchers in providing safe and nutritious food. Food irradiation is one of the most thoroughly investigated food preservation techniques, which has been shown to be effective and safe through extensive research. This process involves exposing food to ionizing radiations in order to destroy microorganisms or insects that might be present on and/or in the food. In addition, the effects of irradiation on the enzymatic activity and improvement of functional properties in food have also been well established. In the present review, the potential of food irradiation technology to address major problems, such as short shelf life, high-initial microbial loads, insect pest management (quarantine treatment) in supply chain, and safe consumption of fresh fruits was described. With improved hygienic quality, other uses, such as delayed ripening and enhanced physical appearance by irradiation were also discussed. Available data showed that the irradiation of fruits at the optimum dose can be a safe and cost-effective method, resulting in enhanced shelf life and hygienic quality with the least amount of compromise on the various nutritional attributes, whereas the consumer acceptance of irradiated fruits is a matter of providing the proper scientific information.
The Nasopharyngeal Microbiota of Children With Respiratory Infections in Botswana

Background: Nearly half of child pneumonia deaths occur in sub-Saharan Africa. Microbial communities in the nasopharynx are a reservoir for pneumonia pathogens and remain poorly described in African children. Methods: Nasopharyngeal swabs were collected from children with pneumonia (N = 204), children with upper respiratory infection symptoms (N = 55) and healthy children (N = 60) in Botswana between April 2012 and April 2014. We sequenced the V3 region of the bacterial 16S ribosomal RNA gene and used partitioning around medoids to cluster samples into microbiota biotypes. We then used multivariable logistic regression to examine whether microbiota biotypes were associated with pneumonia and upper respiratory infection symptoms. Results: Mean ages of children with pneumonia, children with upper respiratory infection symptoms and healthy children were 8.2, 11.4 and 8.0 months, respectively. Clustering of nasopharyngeal microbiota identified 5 distinct biotypes: Corynebacterium/Dolosigranulum-dominant (23%), Haemophilus-dominant (11%), Moraxella-dominant (24%), Staphylococcus-dominant (13%) and Streptococcus-dominant (28%). The Haemophilus-dominant [odds ratio (OR): 13.55; 95% confidence interval (CI): 2.10–87.26], the Staphylococcus-dominant (OR: 8.27; 95% CI: 2.13–32.14) and the Streptococcus-dominant (OR: 39.97; 95% CI: 6.63–241.00) biotypes were associated with pneumonia. The Moraxella-dominant (OR: 3.71; 95% CI: 1.09–12.64) and Streptococcus-dominant (OR: 12.26; 95% CI: 1.81–83.06) biotypes were associated with upper respiratory infection symptoms. In children with pneumonia, HIV infection was associated with a lower relative abundance of Dolosigranulum (P = 0.03). Conclusions: Pneumonia and upper respiratory infection symptoms are associated with distinct nasopharyngeal microbiota biotypes in African children. A lower abundance of the commensal genus Dolosigranulum may contribute to the higher pneumonia risk of HIV-infected children.
Management and long‐term outcome in patients presenting with ictal asystole or bradycardia

Purpose: Ictal asystole (IA) and ictal bradycardia (IB) are rare autonomic symptoms during epileptic seizures and may be potentially life‐threatening. Guidelines for the care of these patients are missing. The aim of this multicenter study was to evaluate the management and long‐term outcome in patients with IA and IB.
In vivo diffusion tensor imaging and ex vivo histologic characterization of white matter pathology in a post–status epilepticus model of temporal lobe epilepsy

Although epilepsy is historically considered a disease of gray matter, recent diffusion tensor imaging (DTI) studies have shown white matter abnormalities in patients with epilepsy. The histopathologic correlate of these findings, and whether they are a cause or consequence of epilepsy, remains unclear. To characterize these changes and their underlying histopathology, DTI was performed in juvenile rats, 4 and 8 weeks after pilocarpine‐induced status epilepticus (SE). In the medial corpus callosum (CC), mean diffusivity and axial diffusivity (MD and λ1) as well as a myelin staining were significantly reduced at 4 weeks. Only the λ1 decrease persisted at 8 weeks. In the fornix fimbriae (FF), λ1 and myelin staining were decreased at both time points, whereas fractional anisotropy (FA) and MD were significantly reduced at 8 weeks only. We conclude that SE induces both transient and chronic white matter changes in the medial CC and FF that are to some degree related to myelin pathology.
Borderline Dravet syndrome: A useful diagnostic category?

The term “borderline” severe myoclonic epilepsy of infancy (SMEIB) has been used to designate patients in whom myoclonic seizures or generalized spike and wave activity are absent. It has also been used loosely to indicate mild forms of the syndrome. It is now acknowledged that the course and outcome of patients with SMEIB are the same as in the core syndrome. The rate of patients exhibiting SCN1A gene mutations is also similar, and it has been observed that the same mutations can cause both typical and “borderline” forms, indicating causal homogeneity. Defining a borderline form of a syndrome would mean setting the criteria of semiology and severity whereby a given phenotype falls within and outside the core syndrome. Such process has never been made for Dravet syndrome and is of course unrealistic in view its polymorphic expression. The eponym Dravet syndrome has been preferred to designate a syndrome spectrum that also embraces SMEIB. Therefore the term “borderline” Dravet syndrome is improper. The definition “mild form” of Dravet syndrome would certainly be more suitable to indicate those patients exhibiting a less severe or incomplete form of the syndrome. Variability in severity favors the concept that SCN1A loss of function causes a spectrum of epilepsy phenotypes in which seizures, often prolonged and precipitated by fever, are the prominent feature and schematic subdivisions would be inappropriate, at least in the early stages. An initial definition of SCN1A gene–related epilepsy would perhaps be more suitable when a mutation of this gene is ascertained and the clinical picture is still ill defined.
Cingulate epileptogenesis in hypothalamic hamartoma

Hypothalamic hamartoma (HH) is a relatively rare cause of epilepsy, mainly affecting children. Nearly all patients develop gelastic seizures, often followed by other focal seizure types. Our case illustrates the mechanisms of epileptogenesis in HH. The patient developed gelastic attacks as a baby, and secondarily generalized seizures and drop attacks at 9 years of age. Magnetic resonance imaging (MRI) confirmed the presence of a HH. Presurgical assessment with intracranial electroencephalography (EEG) monitoring recorded gelastic seizures with generalized epileptiform activity. Functional stimulation of the hamartoma provoked gelastic attacks. Single pulse electrical stimulation (SPES) was used to identify epileptogenic cortex. SPES of the left cingular cortex provoked generalized responses similar to the spontaneous generalized discharges. Our results suggest that long‐standing history of epilepsy in patients with HH may be related to additional sources of epileptogenic activity. Electrical stimulation performed in this patient provided additional data to favor the hypothesis of secondarily epileptogenesis in the cingulate gyrus independently from the primary origin in the HH.
A Randomized Controlled Study of a Fully Liquid DTaP-IPV-HB-PRP-T Hexavalent Vaccine for Primary and Booster Vaccinations of Healthy Infants and Toddlers in Latin America

Background: Hexavalent diphtheria-tetanus-acellular pertussis-inactivated poliovirus-hepatitis B-Haemophilus influenzae type b (DTaP-IPV-HB-PRP-T)–containing vaccines are increasingly the standard of care. This study evaluated the primary series (NCT01177722) and booster (NCT01444781) of a fully liquid DTaP-IPV-HB-PRP-T vaccine in Latin America. Methods: Infants (N = 1375) received hepatitis B vaccine at birth and were randomized to one of 3 batches of the investigational DTaP-IPV-HB-PRP-T or licensed control vaccine (DTaP-HB-IPV//PRP-T) at 2–4 to 6 months of age, coadministered with 7-valent pneumococcal conjugate vaccine (PCV7) (2-4-6 months) and rotavirus vaccine (2–4 months). A booster of either DTaP-IPV-HB-PRP-T or control was given at 12–24 months, coadministered with PCV7. Immunogenicity was assessed by validated assays and safety from parental reports. Results: Primary series seroprotection and vaccine response rates were equivalent for DTaP-IPV-HB-PRP-T batches. For pooled batches, noninferiority to the control vaccine was demonstrated for each antigen. There were no descriptive differences in antibody persistence or booster response between DTaP-IPV-HB-PRP-T and the control. The booster responses to either vaccine following DTaP-IPV-HB-PRP-T primary series or to DTaP-IPV-HB-PRP-T following a control vaccine primary series were similar. The anti-aP component (filamentous hemagglutinin [FHA] and pertussis toxin [PT]) vaccine response and anti-Haemophilus influenzae type b (PRP) series seroprotection (≥0.15 µg/mL) rates were ≥73.0% after 2 primary series doses. Antipyretics had no effect on the immune response, and an extra (oral) polio vaccination had no effect on the antipolio booster response. Responses to PCV7 and rotavirus vaccine were similar for each coadministration. There were no safety concerns observed with any vaccine. Conclusions: These results confirm the suitability of the fully liquid DTaP-IPV-HB-PRP-T vaccine for primary and booster vaccination of infants.
Important Regulatory Aspects in the Receipt of Animal Products by Food Services

ABSTRACT The aim of this study was to review the current legislation and rules in Brazil that involve quality assurance of animal products during food service reception. Published federal legislation and technical regulations were verified to present a broad general approach to raw material reception. Food service determinations included specifications of the criteria for evaluating and selecting suppliers, verifying the transport system, reception area requirements, and inspecting raw material. For product approval, the packaging, labeling, and temperature should be evaluated. However, periodic microbiological, physicochemical, and sensory support assessment analyses are not required for receiving animal products. For the safety of the raw material, it was concluded that the largest impacts came from the regulation and supervision of the food sector provider because of the challenges of food service and a lack of requirements to use more complex evaluation methods during the reception of raw materials.
Modulation of Intestinal Epithelial Defense Responses by Probiotic Bacteria

Probiotics are live microorganisms, which when administered in food confer numerous health benefits. In previous studies about beneficial effects of probiotic bacteria to health, particularly in the fields of intestinal mucosa defense responses, specific probiotics, in a strain-dependent manner, show certain degree of potential to reinforce the integrity of intestinal epithelium and/or regulate some immune components. The mechanism of probiotic action is an area of interest. Among all possible routes of modulation by probiotics of intestinal epithelial cell-mediated defense responses, modulations of intestinal barrier function, innate, and adaptive mucosal immune responses, as well as signaling pathways are considered to play important role in the intestinal defense responses against pathogenic bacteria. This review summarizes the beneficial effects of probiotic bacteria to intestinal health together with the mechanisms affected by probiotic bacteria: barrier function, innate, and adaptive defense responses such as secretion of mucins, defensins, trefoil factors, immunoglobulin A (IgA), Toll-like receptors (TLRs), cytokines, gut associated lymphoid tissues, and signaling pathways.
An Observational Study of Severe Pertussis in 100 Infants ⩽120 Days of Age

Background: Pertussis in young infants is a unique, severe, afebrile, cough illness that is frequently fatal. Methods: All pertussis cases ⩽120 days of age admitted to a pediatric intensive care unit in California between October 1, 2013, and April 25, 2015, were evaluated. Results: Of 100 pertussis patients ⩽120 days of age admitted to pediatric intensive care unit, there were 5 deaths. The white blood cell counts in the fatal cases were significantly higher than in the nonfatal cases. Thirty-four percent of patients were intubated, 18% received inotropic and/or vasoactive support, 22% received steroid, 4% received extracorporal membrane oxygenation, and 3% underwent exchange blood transfusion. The median age at the time of illness onset in the patients who died was 23 days. Conclusions: These data, as well as data from previous California studies, suggest updated strategies for the management of severe pertussis. These include perform serial white blood cell counts, treat all presumptive cases with azithromycin, evaluate for pulmonary hypertension, intubate and administer oxygen for apneic episodes and administer inotropic/vasoactive agents for cardiogenic shock. Do not administer steroids or nitric oxide. Criteria for exchange blood transfusion therapy for leukocytosis with lymphocytosis are suggested.
A comprehensive overview on the micro- and nano-technological encapsulation advances for enhancing the chemical stability and bioavailability of carotenoids

ABSTRACT Carotenoids are lipophilic secondary plant compounds, and their consumption within fruits and vegetables has been positively correlated with a decreased risk of developing several chronic diseases. However, their bioavailability is often compromised due to incomplete release from the food matrix, poor solubility and potential degradation during digestion. In addition, carotenoids in food products are prone to oxidative degradation, not only lowering the nutritional value of the product but also triggering other quality deteriorative changes, such as formation of lipid pro-oxidants (free radicals), development of discolorations or off-flavor defects. Encapsulation refers to a physicochemical process, aiming to entrap an active substance in structurally engineered micro- or nano-systems, in order to develop an effective thermodynamical and physical barrier against deteriorative environmental conditions, such as water vapor, oxygen, light, enzymes or pH. In this context, encapsulation of carotenoids has shown to be a very effective strategy to improve their chemical stability under common processing conditions including storage. In addition, encapsulation may also enhance bioavailability (via influencing bioaccessibility and absorption) of lipophilic bioactives, via modulating their release kinetics from the carrier system, solubility and interfacial properties. In the present paper, it is aimed to present the state of the art of carotenoid microencapsulation in order to enhance storability and bioavailability alike.
Recent developments in high-quality drying of vegetables, fruits, and aquatic products

ABSTRACT Fresh foods like vegetables, fruits, and aquatic products have high water activity and they are highly heat-sensitive and easily degradable. Dehydration is one of the most common methods used to improve food shelf-life. However, drying methods used for food dehydration must not only be efficient and economic but also yield high-quality products based on flavor, nutrients, color, rehydration, uniformity, appearance, and texture. This paper reviews some new drying technologies developed for dehydration of vegetables, fruits, and aquatic products. These include: infrared drying, microwave drying, radio frequency drying, electrohydrodynamic drying, etc., as well as hybrid drying methods combining two or more different drying techniques. A comprehensive review of recent developments in high-quality drying of vegetables, fruits and aquatic products is presented and recommendations are made for future research.
Zoledronic acid - does it have anabolic as well as anti-resorptive effects?

Zoledronic acid is the most recent bisphosphonate to be approved for treatment of osteoporosis in postmenopausal women. It is a third generation aminobisphosphonate with higher binding affinity to bone mineral and greater inhibition of farnesyl diphosphate synthase than any other bisphosphonate in clinical use. In clinical trials, once yearly intravenous infusion of 5 mg for three years resulted in 70%, 25% and 41% reductions in morphometric vertebral, non-vertebral and hip fractures, respectively, in postmenopausal women with osteoporosis (1). In addition, once yearly zoledronic acid was shown to reduce clinical fractures by 35% in men and women who had recently sustained a hip fracture, a benefit that was associated with a significant reduction in mortality (2).
Invasive Haemophilus influenzae Serotype a Infection in Children: Clinical Description of an Emerging Pathogen—Alaska, 2002–2014

Background: Invasive infections from Haemophilus influenzae serotype a (Hia) have been reported with increasing frequency, especially among indigenous populations. However, there are limited population-based studies of clinical severity. We studied invasive Hia infections in Alaska to determine clinical characteristics, mortality and sequelae. Methods: We defined an invasive Hia infection as the first detection of Hia from a usually sterile site in a child <10 years of age from Alaska. We identified cases using the Alaska Invasive Bacterial Diseases Surveillance System and reviewed medical charts up to 2 years after reported illness. Results: We identified invasive Hia infections in 36 children, 28 (78%) <1 year old, 34 (94%) living in an Alaskan village and 25 (69%) without documented underlying illness. Overlapping clinical presentations included meningitis in 15 children (42%); bacteremia and pneumonia in 10 children (28%); and bone, joint or soft tissue infections in 10 children (22%). In 4 other children, no source of invasive infection was identified. Intensive care was provided for 11 children (31%); 12 children (33%) required surgical intervention. One year after infection, 4 children (11%) had died from Hia, and 5 children (14%) had ongoing neurologic sequelae. Conclusions: Invasive Hia infections in Alaska occurred predominantly in Alaska Native infants in rural communities. Although one-third of children had preexisting conditions, most cases occurred without known comorbidity. Clinical syndromes were frequently severe. One year after infection, 1 in 4 children had either died or had neurologic sequelae. An effective vaccine would prevent significant morbidity and mortality in affected populations.
Reputation‐based credibility analysis of Twitter social network users

This paper addresses the problem of finding credible sources among Twitter social network users to detect and prevent various malicious activities, such as spreading false information on a potentially inflammatory topic, forging accounts for false identities, etc. Existing research works related to source credibility are graph‐based, considering the relationships among users to predict the spread information; human‐based, using human perspectives to determine reliable sources; or machine learning‐based, relying on training classifiers to predict users' credibility. Very few of these approaches consider a user's sentimentality when analyzing his/her credibility as a source. In this paper, we propose a novel approach that combines analysis of the user's reputation on a given topic within the social network, as well as a measure of the user's sentiment to identify topically relevant and credible sources of information. In particular, we propose a new reputation metric that introduces several new features into the existing models. We evaluated the performance of the proposed metric in comparison with two machine learning techniques, determining that the accuracy of the proposed approach satisfies the stated purpose of identifying credible Twitter users.
