Duration of Protection Provided by Live Attenuated Influenza Vaccine in Children

Background: Reliable availability of influenza vaccine before October could enable the vaccination of many children who might not otherwise be vaccinated. Methods: Available data for children were analyzed to describe protection provided by live attenuated influenza vaccine (LAIV) for greater than 5 months postvaccination. Results: Four studies conducted in children aged 6 months to 18 years were identified. Culture-confirmed efficacy against A/H1N1 and A/H3N2 strains at 9–12 months postvaccination was 77% [95% confidence interval (CI): 53–89%] to 100% (95% CI: 68–100%) and through a second influenza season without revaccination was 56% (95% CI: 31–73%) and 57% (95% CI: 6–82%), respectively. Against B strains, 1 study demonstrated 86% (95% CI: 59–95%) efficacy at 5–7 months. Another study demonstrated 27% (95% CI: −62% to 67%) efficacy at 9–12 months compared with 74% (95% CI: 39–89%) at 1 to <5 months during a period of antigenic drift for circulating B strains. A third study estimated 50% (95% CI: −49% to 83%) efficacy against influenza B strains through a second season without revaccination. Conclusions: In children, live attenuated influenza vaccine provided sustained protection against influenza illness caused by antigenically similar strains. Efficacy at 1 to <5 months postvaccination was comparable to that at 9–12 months for A/H1N1 and A/H3N2 strains and at 5–7 months for B strains. Meaningful efficacy was seen through a second season without revaccination, although at a lower level than during the first 12 months postvaccination.
Attribute‐based access control management for multicloud collaboration

Security of applications has been identified as one of the major concerns in today's multicloud collaborative environment. These applications are often bounded by the constraints of the disparate cloud domains they are deployed in. A fine‐grained access control mechanism such as attribute‐based access control (ABAC) is considered to be an appropriate choice for authorization management in this context. However, identifying a suitable set of ABAC rules, often called rule mining, is a critical step in building ABAC‐based systems. We propose 2 approaches for intercloud rule formation in ABAC. In the first approach, we consider cross domain rule mining as the problem of forming a minimal set of positive authorizations only. The second approach shows the advantage of developing deny rules along with positive authorizations in reducing the total number of rules, and hence, the response time for evaluating access requests. The problem is proved to be NP‐hard. Heuristic solutions are proposed and evaluated on benchmark datasets showing encouraging results.
The role of nonfat ingredients on confectionery fat crystallization

ABSTRACT Confections such as chocolate and biscuit fillings are composed of a continuous fat phase that contains dispersed nonfat ingredients such as sugar and cocoa powder. Research on fat crystallization and rheology in confections often extrapolates crystallization and textural properties from bulk to mixed systems while overlooking the important role of composition or particle interactions. For example, in chocolate processing the fat phase aids dispersed phase lubrication and fluidity whereas the dispersed particles assist in fat crystallization by providing many nucleation sites. In confections with a high dispersed phase volume fraction, fat crystallization may be hindered due to reduced triacyglycerol mobility, confinement, and increased tortuosity. This is further complicated in systems with slow crystallizing fats such as palm oil whose crystallization is exceptionally sensitive to composition and processing. This review breaks down the physical chemistry of fat-based confections and discusses the impact of different nonfat ingredients towards fat crystallization and rheology. The behavior of palm oil is further highlighted as it is becoming increasingly popular as a confectionery ingredient. Lastly, ingredient-ingredient interactions and their role in fat crystallization are described along with force spectroscopy as a novel tool to characterize such phenomena. Force spectroscopy utilizes atomic force microscopy to measure intermolecular forces as a function of distance but remains largely unexplored in the area of food science.
Do marine algal polyphenols have antidiabetic, antihyperlipidemic or anti-inflammatory effects in humans? A systematic review

ABSTRACT Cardiovascular disease and type 2 diabetes are leading causes of morbidity and mortality globally. Marine algal polyphenols have potential to reduce the risk of these conditions, however, little is known about their impact in humans. This systematic review investigates the antidiabetic, antihyperlipidemic and anti-inflammatory effects of marine polyphenols in humans. Scopus, Medline, PsychInfo, Embase and Cochrane Library databases were searched in November 2016. Eligible studies included (1) human adults, (2) marine polyphenol intervention, (3) blood lipid, glucose, insulin or inflammatory marker outcomes, and (4) were a randomized-controlled trial. One postprandial cross-over trial and four parallel design trials were included involving 271 adults. Analysis across studies was performed using Cohen's d effect sizes. Supplementation with polyphenol-rich extracts had small-to-medium positive effects on fasting blood glucose, total cholesterol and LDL-cholesterol; however, there is inadequate evidence as yet to confirm if these are consistent effects. Further randomized-controlled trials should investigate polyphenols from Ecklonia cava and other macroalgal sources, to determine if there is a role for marine polyphenols in reducing the risk factors of chronic disease in humans.

Platelet function monitoring in patients on clopidogrel

Abstract Clopidogrel is essential to prevent recurrent ischemic events in patients with acute coronary syndromes and after percutaneous coronary interventions (PCIs). However, platelet reactivity after clopidogrel treatment is not uniform, and high on-treatment platelet reactivity (HTPR) persists in approximately one third of patients receiving clopidogrel. As recent observational studies suggest that HTPR is associated with higher risk of ischemic events, including cardiovascular death, myocardial infarction and stent thrombosis, it seems rational to monitor post-clopidogrel platelet reactivity for risk assessment and to tailor anti-platelet therapy for patients with HTPR. However, routine platelet function monitoring is not recommended by current clinical guidelines. The article aims to review the available evidence on the clinical relevance of platelet function monitoring, highlighting possible reasons for the conflict between guidelines and observational studies.
The psychosocial and occupational impact of chronic skin disease

ABSTRACT: Chronic skin diseases, particularly psoriasis and atopic dermatitis, have a negative impact on patients’ quality of life. Patients often experience significant psychological and social distress such as increased levels of depression and fear of stigma. Skin diseases can also impact patients’ occupational lives by causing them to miss work or be less productive. Quality of life instruments provide important information for healthcare professionals, the general public, and those involved in distribution of healthcare resources, which helps prevent chronic skin disease from being overlooked amidst other medical conditions.
Management of cutaneous tuberculosis

ABSTRACT: Cutaneous tuberculosis (TB) is an extrapulmonary form of tuberculosis, which may be classified based on the immunologic state of the host. Chemotherapy still remains the treatment of choice. The management of cutaneous TB follows the same guidelines as that of TB of other organs, which can be treated with a short course four‐agent chemotherapeutic regimen given for 2 months followed by a two‐drug regimen for the next 4 months. This chapter highlights current treatment recommendations for cutaneous TB. The important factors to consider in the choice of optimal treatment includes the type of cutaneous involvement, stage of the disease, level of immunity, and general condition of the patient. The highest priority in any cutaneous TB control program is the proper, accurate, and rapid detection of cases and the availability of chemotherapy to all tuberculosis patients until cure. Contact tracing is also an important component of efficient tuberculosis control.
Which paradigm should I use? An analytical comparison of the client–server, remote evaluation and mobile agent paradigms

In this paper we deal with the study of the actual convenience of using the agent programming paradigm for accesssing distributed service. We try to point out the benefits of such a communication paradigm, by providing an analytical study of its basic features in comparison with the client–server approach and remote evaluation. The aim of the paper is to show how the Petri net analysis technique can be used for deciding whether to use traditional client/server, remote evaluation or mobile agents paradigm in designing a particular evaluation. So, we present several models of non‐Markovian Petri nets, which have been solved through the WebSPN tool, and we provide a close comparison between the agents technique, the client‐server and the remote evaluation communication paradigm. The results that we have obtained show how agents must not always be considered the only solution to any communication issue, since in several cases their use might even reveal a drawback. We also focus out attention on providing some practical remarks, which can help the developer during the design in order to select the communication paradigm which best suits the features of the application that has to be developed.

Emerging Macrolide Resistance in Mycoplasma pneumoniae in Children: Detection and Characterization of Resistant Isolates

Background: Epidemiologic data from Asia have documented the rapid and extensive emergence of macrolide resistance in Mycoplasma pneumoniae. This drug resistance has also been documented in Europe and recently in the United States, but there is very little information currently available on its prevalence. A rapid technique to identify macrolide-resistant M. pneumoniae is needed to guide management of patients with community-acquired respiratory infections. Methods: Culture and Minimum Inhibitory Concentration testing identified macrolide-resistant M. pneumoniae infection in 2 seriously ill hospitalized children with community-acquired pneumonia. A portion of the 23S ribosomal RNA gene from 2 macrolide-resistant M. pneumoniae isolates from these children as well as 4 laboratory-induced macrolide-resistant strains was amplified by PCR, and the PCR products were sequenced to identify mutations associated with macrolide resistance. A real-time PCR assay was designed to identify 3 known mutations in the 23S rRNA gene associated with macrolide resistance and applied to the clinical specimens from which these isolates were obtained and to the bacterial isolates. Results: Macrolide-resistant M. pneumoniae from both children were found to carry an A2063G transition in the 23S rRNA gene previously identified in resistant isolates from China, Japan, France, and recently in an encephalitis outbreak in Rhode Island. Three laboratory-induced mutant strains had an A2064G mutation whereas the other one had an A2063G mutation. A real-time PCR assay successfully detected the macrolide-resistant M. pneumoniae directly in clinical specimens and discriminated them from wild-type isolates. Conclusions: Macrolide-resistant M. pneumoniae can be associated with prolonged severe respiratory infection in children. Real-time PCR offers a rapid method of diagnosing macrolide resistance in community-acquired respiratory infections due to M. pneumoniae.
Cutaneous and mucocutaneous leishmaniasis

Leishmaniasis is a cluster of diseases caused by protozoa in the genus Leishmania. There are three basic clinical forms: cutaneous, mucocutaneous, and visceral leishmaniasis. The present review focuses on the diagnosis and treatment of cutaneous and mucocutaneous leishmaniasis. Characteristics of both the human host and the parasite species influence the clinical disease manifestations that range from asymptomatic exposure, to self‐healing skin ulcers, to life‐threatening widespread destructive ulcerations. Whether through medical treatment or through spontaneous resolution, skin ulcerations generally result in disfiguring scars with significant social and economic impact. Tests to confirm the diagnosis should be performed on patients who have recently visited endemic areas and have skin or mucosal manifestations consistent with leishmaniasis. Treatment depends on the species of Leishmania and the risk of widespread or disfiguring disease. Because of increasing trends in global travel, educating health care providers to recognize and treat leishmaniasis in both endemic and non‐endemic countries is imperative.
A cache‐efficient implementation of the lattice Boltzmann method for the two‐dimensional diffusion equation

The lattice Boltzmann method is an important technique for the numerical solution of partial differential equations because it has nearly ideal scalability on parallel computers for many applications. However, to achieve the scalability and speed potential of the lattice Boltzmann technique, the issues of data reusability in cache‐based computer architectures must be addressed. Utilizing the two‐dimensional diffusion equation, $T_t=\mu(T_{xx}T_{yy})$, this paper examines cache optimization for the lattice Boltzmann method in both serial and parallel implementations. In this study, speedups due to cache optimization were found to be 1.9–2.5 for the serial implementation and 3.6–3.8 for the parallel case in which the domain decomposition was optimized for stride‐one access. In the parallel non‐cached implementation, the method of domain decomposition (horizontal or vertical) used for parallelization did not significantly affect the compute time. In contrast, the cache‐based implementation of the lattice Boltzmann method was significantly faster when the domain decomposition was optimized for stride‐one access. Additionally, the cache‐optimized lattice Boltzmann method in which the domain decomposition was optimized for stride‐one access displayed superlinear scalability on all problem sizes as the number of processors was increased.

Detection of Cytomegalovirus DNA in Dried Blood Spots of Minnesota Infants Who Do Not Pass Newborn Hearing Screening

Background: Up to 15% of infants with asymptomatic congenital cytomegalovirus (CMV) infection will experience some degree of sensorineural hearing loss. Many infants who fail newborn hearing screening (NHS) are likely to have congenital CMV infection, but may escape definitive virologic identification because diagnostic evaluation may not commence until several weeks or months of age, making differentiation between congenital and postnatal CMV infection difficult. Early diagnosis linking virologic identification of congenital CMV infection to infants failing NHS may improve diagnostic precision and enhance opportunities for therapeutic intervention. Methods: The goal of this study was to compare newborn dried blood spots from Minnesota infants who had failed NHS, and were designated for referral, with control infants who passed NHS, for the presence of CMV DNA by real-time PCR, using hybridization probes for the CMV gene UL54. Results: Of 479 infants with a failed NHS (bilateral failure), 13 had CMV DNA present in the blood spot (2.7%). This compared with only 2/479 positive results from a control group of infants who passed the NHS (0.4%; P = 0.007, Fisher exact test). Comparisons of the glycoprotein B (gB) genotype as well as direct DNA sequencing of selected positives revealed that PCR positive samples represented unique clinical isolates. The mean viral load among the 15 positive samples was 1.6 × 103 genomes/microgram of total DNA. Conclusions: Newborn bloodspot CMV screening by real-time PCR may be a useful and rapid adjunct to functional NHS and may enable more rapid etiologic diagnosis of sensorineural hearing loss in newborns.
Antibiotic Use in Neonatal Intensive Care Units and Adherence With Centers for Disease Control and Prevention 12 Step Campaign to Prevent Antimicrobial Resistance

Background: The Centers for Disease Control and Prevention (CDC) 12-Step Campaign to Prevent Antimicrobial Resistance was launched to educate clinicians about antimicrobial resistance and provide strategies to improve clinical practice, including antimicrobial utilization. Methods: A multicenter retrospective observational study of antibiotic use was performed in 4 tertiary care NICUs to assess adherence to the guidelines defined by the CDC 12-Step Campaign using predetermined criteria. Fifty infants per NICU were identified who received intravenous antibiotics at greater than 72 hours of age. Antibiotic regimens, clinical and microbiologic data, and indications for initiation and continuation of antibiotics (after 72 hours of use) were recorded. Inappropriate utilization was characterized at initiation, continuation, by agent, and by CDC 12-Step. Results: Two hundred neonates received 323 antibiotic courses totaling 3344 antibiotic-days. Ninety (28%) courses and 806 (24%) days were judged to be nonadherent to a CDC 12-Step. Inappropriate use was more common with continuation of antibiotics (39%) than with initiation (4%) of therapy. Vancomycin was the most commonly used drug (n = 895 antibiotic-days) of which 284 (32%) days were considered inappropriate. Carbapenems were used less frequently (n = 310 antibiotic-days), and 132 (43%) of these days were inappropriate. Common reasons for nonadherence at the time of continuation included failure to narrow antibiotic coverage after microbiologic results were known and prolonged antibiotic prophylaxis after surgery with chest tube placement. Conclusions: The CDC 12-Step Campaign can be modified for neonatal populations. Inappropriate antibiotic prescribing was common in the study NICUs. Improvement efforts should target antibiotic use 72 hours after initiation, particularly focusing on narrowing therapy and instituting protocols to limit prophylaxis.
Antimicrobial photodynamic therapy – what we know and what we don’t

Abstract Considering increasing number of pathogens resistant towards commonly used antibiotics as well as antiseptics, there is a pressing need for antimicrobial approaches that are capable of inactivating pathogens efficiently without the risk of inducing resistances. In this regard, an alternative approach is the antimicrobial photodynamic therapy (aPDT). The antimicrobial effect of aPDT is based on the principle that visible light activates a per se non-toxic molecule, the so-called photosensitizer (PS), resulting in generation of reactive oxygen species that kill bacteria unselectively via an oxidative burst. During the last 10–20 years, there has been extensive in vitro research on novel PS as well as light sources, which is now to be translated into clinics. In this review, we aim to provide an overview about the history of aPDT, its fundamental photochemical and photophysical mechanisms as well as photosensitizers and light sources that are currently applied for aPDT in vitro. Furthermore, the potential of resistances towards aPDT is extensively discussed and implications for proper comparison of in vitro studies regarding aPDT as well as for potential application fields in clinical practice are given. Overall, this review shall provide an outlook on future research directions needed for successful translation of promising in vitro results in aPDT towards clinical practice.
Derivation of inhalation toxicity reference values for propylene oxide using mode of action analysis: Example of a threshold carcinogen

Propylene oxide (PO) is an important industrial chemical used primarily in the synthesis of other compounds. Inhalation carcinogenesis studies in rodents, with no-observed-adverse-effect levels (NOAELs) of 100 and 200 ppm, have revealed that chronic, high exposure to PO can induce tumors at the site of contact. Despite these characteristics, there is no evidence that typical environmental or occupational exposures to PO constitute a health risk for humans. The nongenotoxic effects of PO (glutathione depletion and cell proliferation) that augment its DNA-reactive and non-DNA-reactive genotoxicity are expected to be similar in humans and rodents. Available evidence on mode-of-action suggests that cancer induction by PO at the site of contact in rodents is characterized by a practical threshold. Human toxicity reference values for potential carcinogenic effects of PO were derived based on nasal tumors identified in rodent studies and specified uncertainty factors. The 95% lower confidence limit on the dose producing a 10% increase in additional tumor risk (LED10) was calculated using the rat and mouse data sets. The human reference values derived from the rat and mouse LED10 values were 0.7 and 0.5 ppm PO, respectively. A similar noncancer reference value, 0.4 ppm, was derived on the basis of non-neoplastic nasal effects in rats.
Physiology of IgD. IV. Enhancement of antibody production in mice bearing IgD-secreting plasmacytomas

Immune responses to trinitrophenylated hemocyanin (TNP-KLH), Ficoll (TNP-Ficoll), and Brucella abortus (TNP-BA) were examined in BALB/c mice bearing subcutaneous transplants of TEPC-1017 and TEPC-1033, the two known IgD-secreting BALB/c plasmacytomas. Both primary and secondary 19S and 7S splenic plaque-forming cell (PFC) responses in spleen to intravenously injected TNP-KLH were enhanced three to fivefold. Primary responses to TNP-Ficoll were 1.5-2 times higher than in control mice (particularly the 7S PFC response). Primary responses to TNP-BA were enhanced by TEPC-1017 but suppressed by TEPC-1033, while secondary responses to TNP-BA were enhanced three to sevenfold by both tumors. Intraperitoneal injections of ascites fluid from mice bearing TEPC-1017 or TEPC-1033, or of IgD isolated from such ascites fluid, caused a similar enhancement of the primary response to TNP-KLH, as did the tumor itself, particularly when injected approximately 1 wk before antigen injection. IgD-containing ascites fluid had no effect on the response of athymic (nu/nu) BALB/c mice to TNP-KLH. These findings suggest the existence of an IgD-responsive immunoregulatory T cell.
Validation of a Chinese Version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale in Patients with Hypertension in Primary Care

The aim of this study was to validate a Chinese version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale (SES6C). In 2012, a cross-sectional study was conducted in a community clinic, in Beijing, China. A total of 262 hypertension patients participated in this study. Concurrent validity was validated by Pearson’s correlations between the SES6C and Hospital Anxiety and Depression Scale (HADS). Intraclass correlation coefficients (ICC) were performed to evaluate test-retest reliability of the scale. Related factors of self-efficacy were explored in linear regression models. The results of our study display acceptable psychometric properties: the scale was two-dimensional, reproducible (ICC = 0.78; 95% CI, 0.70–0.84), and the reliability was good (Cronbach’s alpha = 0.88). Significant (; ) correlation was found between the level of self-efficacy and the level of psychological distress. In multivariable analysis, the factors significantly associated with self-efficacy were regular exercise (, ), HADS total score (, ) and health status (, ). The study provides evidence that the SES6C is acceptable, valid and repeatable for hypertension patients.
