Published: August 2017

The back cover picture shows schematic of direct in situ liquid cell TEM observation of electron bean induced growth and self‐assembly of nanoclusters in water with the aid of a triblock copolymer. The growth and self‐assembly of the Pt nanoclusters with the aid of triblock copolymer F127 are directly observed, and a surfactant guided nanocluster formation mechanism is proposed. Dramatic differences are found on the cluster forming behavior and final morphologies between thick and thin liquid regions. The difference in precursor availability and charging effects are attributed to the different growth behavior in different thickness regions. More details are discussed in the article by Chen et al. on page 1278–1283.

Discrepant HPV/cytology cotesting results: Are there differences between cytology‐negative versus HPV‐negative cervical intraepithelial neoplasia?
Authors: Tracht Jessica M. , Davis Antoinette D. , Fasciano Danielle N. , Eltoum Isam‐Eldin A. 
Published: August 2017

BACKGROUNDThe objective of this study was to compare cervical high‐grade squamous intraepithelial lesions subcategorized as cervical intraepithelial neoplasia‐3 (CIN‐3)–positive after a negative cytology result but positive for high‐risk human papillomavirus (HR‐HPV) testing to those with a negative HR‐HPV test but positive cytology (atypical squamous cells of undetermined significance [ASCUS]‐positive/HPV‐negative) and to assess reasons for discrepancies.METHODSThe authors retrospectively analyzed women who underwent screening with cytology and HPV testing from 2010 through 2013. After a review of surgical specimens and cytology, discrepancies were classified as sampling or interpretation error. Clinical and pathologic findings were compared.RESULTSIn total, 15,173 women (age range, 25‐95 years; 7.1% were aged < 30 years) underwent both HPV and cytologic testing, and 1184 (8.4%) underwent biopsy. Cytology was positive in 19.4% of specimens, and HPV was positive in 14.5%. Eighty‐four CIN‐3–positive specimens were detected, including 55 that tested ASCUS‐positive/HPV‐positive, 11 that tested negative for intraepithelial lesion or malignancy (NILM)/HPV‐positive, 10 that tested ASCUS‐positive/HPV‐negative, 3 that tested NILM/HPV‐negative, and 5 tests that were unsatisfactory. There was no significant difference between NILM/HPV‐positive and ASCUS‐positive/HPV‐negative CIN‐3 in terms of size, time to occurrence, the presence of a cytopathic effect, screening history, race, or age. Six of 11 NILM/HPV‐positive cases were reclassified as ASCUS, indicating an interpreting error of 55% and a sampling error of 45%. No ASCUS‐positive/HPV‐negative cases were reclassified. Seven cases of CIN‐3 with positive cytology were HPV‐negative.CONCLUSIONSThere are no significant clinical or pathologic differences between NILM/HPV‐positive and ASCUS‐positive/HPV‐negative CIN‐3–positive specimens. Cytologic sampling or interpretation remains the main reason for discrepancies. However, HPV‐negative CIN‐3 with positive cytology exists and may be missed by primary HPV screening.

AbstractTitania anatase nanocrystals were prepared by sol‐gel/solvothermal synthesis in oleic acid at 250 °C, and modified by co‐reaction with Mo chloroalkoxide, aimed at investigating the effects on gas‐sensing properties induced by tailored nanocrystals surface modification with ultra‐thin layers of MoOx species. For the lowest Mo concentration, only anatase nanocrystals were obtained, surface modified by a disordered ultra‐thin layer of mainly octahedral MoVI oxide species. For larger Mo concentrations, early MoO2 phase segregation occurred. Upon heat treatment up to 500 °C, the sample with the lowest Mo concentration did not feature any Mo oxide phase segregation, and the surface Mo layer was converted to dense octahedral MoVI oxide. At larger Mo concentrations all segregated MoO2 was converted to MoO3. The two different materials typologies, depending on the Mo concentration, were used for processing gas‐sensing devices and tested toward acetone and carbon monoxide, which gave a greatly enhanced response, for all Mo concentrations, to acetone (two orders of magnitude) and carbon monoxide with respect to pure TiO2. For the lowest Mo concentration, dye‐sensitized solar cells were also prepared to investigate the influence of anatase surface modification on the electrical transport properties, which showed that the charge transport mainly occurred in the ultra‐thin MoOx surface layer.

Published: August 2017

AbstractIntegration of coordination polymers and metal–organic frameworks into real applications requires a processing step at the nanoscale. However, their synthesis in the form of nanoparticles with controlled size, shape and organization remains a challenge faced by diverse scientific communities. Ordered mesoporous silica monolith with 2D‐hexagonal structure of the mesopores is used to form ferromagnetic NiFe Prussian blue analog (PBA) nanoparticles with anisotropic shape. The PBA nanowires formed within the nanochannels of the monolith are made of single chains of nanocrystals. Furthermore, when using an ordered mesoporous silica monolith instead of the more frequently used mesoporous powders a parallel organization of the pores is achieved over whole macroscopic fragments of the monolith. A 1×1×1 mm3 fragment of monolith exhibits a remarkably strong anisotropy in its magnetic properties, arising from unprecedented magnetic dipolar interaction along the chains of coordination nanocrystals, which is spread to the macroscopic scale thanks to the long‐range organization of the pores. As various confined chemistries can be developed within the ordered porosity of such monolith, this tool opens up new opportunities for the development of original nanostructured materials exhibiting anisotropy in their properties at the macroscopic scale.
Bioequivalence and Safety of Twice‐Daily Sustained‐Release Paracetamol (Acetaminophen) Compared With 3‐ and 4‐Times‐Daily Paracetamol: A Repeat‐Dose, Crossover Pharmacokinetic Study in Healthy Volunteers
Authors: Liu Dongzhou J. , Collaku Agron 
Published: August 2017

AbstractTwice‐daily sustained‐release (SR) paracetamol (acetaminophen) offers convenient administration to chronic users. This study investigated at steady state (during the last 24 hours of a 3‐day dosing period) the pharmacokinetics, bioequivalence, and safety of twice‐daily SR paracetamol compared with extended‐release (ER) and immediate‐release (IR) paracetamol. In this open‐label, randomized, multidose, 3‐way crossover study, 28 healthy subjects received paracetamol SR (2 × 1000 mg twice daily), ER (2 × 665 mg 3 times daily), and IR (2 × 500 mg 4 times daily). At steady state, twice‐daily SR paracetamol was bioequivalent to ER and IR paracetamol. The 90% confidence intervals for the ratios of geometric means were within the acceptance interval for SR/ER paracetamol (AUC0–t, 0.973–1.033; AUC0–24, 0.974–1.034; AUC0–∞, 0.948–1.011; Cmax, 1.082–1.212; Cav, 1.011–1.106) and SR/IR paracetamol (AUC0–t, 0.969–1.029; AUC0–24, 0.968–1.027; AUC0–∞, 0.963–1.026; Cmax, 0.902–1.010; Cav, 1.004–1.098). Given twice daily, the SR formulation demonstrated SR properties as expected. Mean time at or above a 4 μg/mL plasma concentration of paracetamol from 2 daily doses of the SR formulation was significantly longer than that from 4 daily doses of IR paracetamol. SR formulation also had a greater Tmax, a longer half‐life, and lower Cmin compared with ER and IR paracetamol. All formulations were well tolerated.
SLA‐based PaaS profit optimization

Published: August 2017

SummaryThe socioeconomic impact of cloud solutions and particularly PaaS (platform as a service) solutions is becoming increasingly critical. The main objective of PaaS providers is to generate the maximum profit from the services they provide. This requires them to face a number of challenges such as efficiently managing the underlying resources and satisfying the SLAs of the hosted applications. In this paper, we consider a cloud‐bursting PaaS environment where the PaaS provider owns some private resources and is able to rent public cloud resources on demand. In that context, we propose a profit‐efficient solution for managing such a system under SLA constraints. We define a profit optimization policy that evaluates the cost of hosting each application using public and private resources and chooses the option that generates the highest profit. During peak periods, the optimization policy considers two more options. The first option is to obtain some resources from running applications, taking into account the payment of penalties if their promised quality of service is affected. The second option is to wait until private resources become available, taking into account the payment of penalties if the quality of service promised to the new application is affected. Furthermore, we designed and implemented an open cloud‐bursting PaaS system, called Meryn, which integrates the proposed optimization policy and provides support for batch and MapReduce applications. The results of our evaluation show the effectiveness of our approach in optimizing the provider profit. Indeed, compared to a basic approach, our approach provides up to 11.59% and 9.02% more provider profit in, respectively, simulations and experiments.

AbstractBipolar materials, which work as both the cathode and anode material in aqueous sodium‐ion batteries, have advantages over aqueous electrolytes such as the low cost of sodium and high convenience of the material processing. However, the available materials are greatly limited. Herein, Prussian blue FeFe(CN)6 nanocubes were successfully synthesized by using a modified co‐precipitation method. Owing to the well‐separated redox reactions, fair cycling stability and rate capability of FeFe(CN)6, it could be developed as a bipolar material in an aqueous sodium‐ion battery. The as‐obtained full battery exhibits good cycling stability and rate capability. It was able to deliver a capacity of 32 mA h g−1 at 20 C, 76 % of the capacity at 2 C. After 200 cycles at 2 C, 97 % of the initial capacity was maintained for this battery, which suggests good cycling stability.

BackgroundFast and reliable diagnostics are important in febrile patients admitted to the emergency department. Current urine diagnostics are fast but moderately reliable or reliable but time consuming. Flow cytometry (FC) is a new promising technique in the diagnostics of complicated urinary tract infections by counting bacteria in urine samples. The aim of this study is to improve the FC method by counting only viable bacteria.MethodsUrine was obtained from 135 consecutive febrile patients at the emergency department. According to protocol regular diagnostic urine tests were performed. In addition, FC counting of viable and non‐viable bacteria was executed after staining with thiazole orange and propidium iodide. All test results were compared to the results of urine culture (≥ 105 colony forming units/mL).ResultsAt a cut‐off value of 2.01 × 105 viable bacteria/mL the sensitivity was 100% and specificity was 78.4% (AUC‐value 0.955 on ROC‐curve). Spearman correlation test exhibited a higher correlation for flow cytometric counting of only viable bacteria than counting of all bacteria (0.59 vs. 0.37). Using ROC‐curves, the AUC‐values for FC counting of all bacteria, only viable bacteria and Gram staining were respectively 0.935, 0.955, and 0.968 (P > 0.05).ConclusionFC counting of only viable bacteria can predict quickly and reliably positive and negative urine cultures in febrile patients admitted to the emergency department. It can help to improve the speed and accuracy of the diagnostic procedure at the emergency department. © 2017 Clinical Cytometry Society

Published: August 2017

AbstractObjectiveThe efficacy of bariatric surgery has been proven; however, a subset of patients fails to achieve expected long‐term weight loss postoperatively. As differences in surgery outcome may be influenced by heterogeneous psychological profiles in prebariatric patients, previous subtyping models differentiated patients based on temperament traits. The objective of this study was to expand these models by additionally considering emotion dysregulation and disinhibited eating behaviors for subtyping, as these factors were associated with maladaptive eating behaviors and poor postbariatric weight loss outcome.MethodWithin a prospective multicenter registry, N = 370 prebariatric patients were examined using interview and self‐report questionnaires. A latent profile analysis was performed to identify subtypes based on temperament traits, emotion dysregulation, and disinhibited eating behaviors.ResultsFive prebariatric subtypes were identified with specific profiles regarding self‐control, emotion dysregulation, and disinhibited eating behaviors. Subtypes were associated with different levels of eating disorder psychopathology, depression, and quality of life. The expanded model increased variance explanation compared to temperament‐based models.ConclusionBy adding emotion dysregulation and disinhibited eating behaviors to previous subtyping models, specific prebariatric subtypes emerged with distinct psychological deficit patterns. Future investigations should test the predictive value of these subtypes for postbariatric weight loss and health‐related outcomes.

AbstractDispersal is a driving factor in the creation and maintenance of biodiversity, yet little is known about the effects of habitat variation and geography on dispersal and population connectivity in most mammalian groups. Bats of the family Molossidae are fast‐flying mammals thought to have potentially high dispersal ability, and recent studies have indicated gene flow across hundreds of kilometers in continental North American populations of the Brazilian free‐tailed bat,Tadarida brasiliensis. We examined the population genetics, phylogeography, and morphology of this species in Florida and across islands of The Bahamas, which are part of an island archipelago in the West Indies. Previous studies indicate that bats in the family Phyllostomidae, which are possibly less mobile than members of the family Molossidae, exhibit population structuring across The Bahamas. We hypothesized thatT. brasiliensiswould show high population connectivity throughout the islands and thatT. brasiliensiswould show higher connectivity than two species of phyllostomid bats that have been previously examined in The Bahamas. Contrary to our predictions,T. brasiliensisshows high population structure between two groups of islands in The Bahamas, similar to the structure exhibited by one species of phyllostomid bat. Phylogenetic and morphological analyses suggest that this structure may be the result of ancient divergence between two populations ofT. brasiliensisthat subsequently came into contact in The Bahamas. Our findings additionally suggest that there may be cryptic species withinT. brasiliensisin The Bahamas and the West Indies more broadly.
Phenotypic selection on flowering phenology and pollination efficiency traits between Primula populations with different pollinator assemblages
Authors: Wu Yun , Li Qing‐Jun 
Published: August 2017

AbstractFloral traits have largely been attributed to phenotypic selection in plant–pollinator interactions. However, the strength of this link has rarely been ascertained with real pollinators. We conducted pollinator observations and estimated selection through female fitness on flowering phenology and floral traits between two Primula secundiflora populations. We quantified pollinator‐mediated selection by subtracting estimates of selection gradients of plants receiving supplemental hand pollination from those of plants receiving open pollination. There was net directional selection for an earlier flowering start date at populations where the dominant pollinators were syrphid flies, and flowering phenology was also subjected to stabilized quadratic selection. However, a later flowering start date was significantly selected at populations where the dominant pollinators were legitimate (normal pollination through the corolla tube entrance) and illegitimate bumblebees (abnormal pollination through nectar robbing hole which located at the corolla tube), and flowering phenology was subjected to disruptive quadratic selection. Wider corolla tube entrance diameter was selected at both populations. Furthermore, the strength of net directional selection on flowering start date and corolla tube entrance diameter was stronger at the population where the dominant pollinators were syrphid flies. Pollinator‐mediated selection explained most of the between‐population variations in the net directional selection on flowering phenology and corolla tube entrance diameter. Our results suggested the important influence of pollinator‐mediated selection on floral evolution. Variations in pollinator assemblages not only resulted in variation in the direction of selection but also the strength of selection on floral traits.

In this study, the anti‐obesity effect of oolong tea polyphenols–phospholipids complex (OTC) was investigated. OTC was prepared with oolong tea polyphenols (OTP) and phospholipids, and exhibited higher stability than OTP in vitro. Then high fat diet‐induced obesity human flora‐associated (HFA) mice model were obtained, and the administration of both OTP and OTC alleviated the changes of the serum and liver levels induced by high fat diet dramatically. The numbers (log10 cell mL−1) of Bifidobacterium and Lactobacillus/Enterococcus spp., Bacteroides‐Prevotella and Clostridium histolyticum in obesity models fed with OTC after 8 weeks were 8.28 ± 0.03, 8.21 ± 0.01, 7.23 ± 0.02, and 7.05 ± 0.03 compared with 8.21 ± 0.02, 8.07 ± 0.02, 7.31 ± 0.02, and 7.10 ± 0.01, respectively, in the control. Together, it confirmed the potential of phospholipids in the promotion of intestinal transport of polyphenols, suggesting OTC may have prebiotic‐like activity to prevent obesity‐related metabolic disorders.Oolong tea polyphenols–phospholipids complex show modulatory effect on the intestinal microbiota of high fat diet‐induced obesity mice model, and may have prebiotic‐like activity contributing to the prevention of obesity.
Chronic widespread pain prevalence in the general population: A systematic review

Published: August 2017

AbstractChronic widespread pain (CWP) is a significant burden in communities. Understanding the impact of population‐dependent (e.g., age, gender) and contextual‐dependent (e.g. survey method, region, inequality level) factors have on CWP prevalence may provide a foundation for population‐based strategies to address CWP. Therefore, the purpose of this study was to estimate the global prevalence of CWP and evaluate the population and contextual factors associated with CWP. A systematic review of CWP prevalence studies (1990–2017) in the general population was undertaken. Meta‐analyses were conducted to determine CWP prevalence, and study population data and contextual factors were evaluated using a meta‐regression. Thirty‐nine manuscripts met the inclusion criteria. Study CWP prevalence ranged from 1.4% to 24.0%, with CWP prevalence in men ranging from 0.8% to 15.3% and 1.7% to 22.1% in women. Estimated overall CWP prevalence was 9.6% (8.0–11.2%). Meta‐regression analyses showed gender, United Nations country development status, and human development index (HDI) influenced CWP prevalence, while survey method, region, methodological and reporting quality, and inequality showed no significant effect on the CWP estimate. Globally CWP affects one in ten individuals within the general population, with women more likely to experience CWP than men. HDI was noted to be the socioeconomic factor related to CWP prevalence, with those in more developed countries having a lower CWP prevalence than those in less developed countries. Most CWP estimates were from developed countries, and CWP estimates from countries with a lower socioeconomic position is needed to further refine the global estimate of CWP.SignificanceThis systematic review and meta‐analysis updates the current global CWP prevalence by examining the population‐level (e.g. age, gender) and contextual (e.g. country development status; survey style; reporting and methodologic quality) factors associated with CWP prevalence. This analyses provides evidence to support higher levels of CWP in countries with a lower socioeconomic position relative to countries with a higher socioeconomic position.
