Published: February 2020

SummaryObjectiveThe aim of this systematic review was to determine which evidence level supports maxillary advancement after bone-anchored maxillary protraction (BAMP) in growing patients compared to controls.Search methodsPubMed, Cochrane, Embase, Scopus, and Web-of-Science databases were searched with no restrictions on publication status or year.Selection criteriaProspective and retrospective human studies about BAMP, in at least three patients, were included. Authors were contacted when necessary, and reference lists of the included studies were screened.Data collection and analysisTwo authors undertook independent data extraction with conflict resolution by a third author. Risks of bias were assessed. A meta-analysis for estimates of changes for ANB angle, Wits appraisal, and incisor to mandibular plane angle (IMPA) angle of BAMP treatment compared to control groups was performed.ResultsA total of 449 articles were initially retrieved; 28 full-text articles met the inclusion criteria. Sample sizes ranged from 3 to 52 patients. There was heterogeneity in cephalometric outcomes reported, which prevented the comparison of certain outcomes. ANB angle improved more with BAMP in the maxilla combined with facemask (bone-anchored facemask, BAFM) compared to traditional facemask therapy: this was statistically but not clinically significant (0.2 degrees). No data are available for BAMP with skeletal anchorage in both jaws in combination with Class III elastics (bone-anchored Class III elastics, BAC3E). Likewise, no statistically significant differences in Wits appraisal were found (less than 1 mm). Lower incisor retroclination and facial height seemed to be better controlled with BAC3E compared to BAFM.ConclusionsThe level of evidence available to support the maxillary advancement effect after BAMP was low. Publications reporting results based on identical samples tended to suggest overly positive results of BAMP. The differences in sagittal correction between BAMP and traditional facemask therapy were small and of questionable clinical significance. Long-term follow-up results are not available and, therefore, much needed.LimitationsMost articles had a low level of evidence and some included a historical control group.RegistrationPROSPERO database number CRD42015023366.
The relationship between physical activity and out-of-pocket health care costs of the elderly in Europe
Authors: Dallmeyer Sören , Wicker Pamela , Breuer Christoph 
Published: February 2020

Abstract

Background
Increasing health care costs represent an economic burden placed on individuals across many European countries. Against this backdrop, the aim of this study was to examine the relationship between participation in physical activity and out-of-pocket health care costs in Europe.

Methods
Individual data from the cross-national Survey of Health, Ageing and Retirement (n = 94 267) including 16 European countries were utilized. Two-part models were estimated to investigate how different levels of participation frequency in physical activity are related to out-of-pocket costs (OOPC) for people aged 50 years and older.

Results
Only participation in physical activity more than once a week significantly decreases the probability of incurring any OOPC. However, all frequencies of physical activity significantly reduce the level of costs, with the highest savings being generated by participation once a week. The results reveal higher savings for men compared to women.

Conclusion
Physical activity can be a useful policy instrument to reduce the economic burden of out-of-pocket health care costs for an aging population in Europe. Public officials should primarily promote physical activity interventions targeting older people who are not active at all.
Initially Negative Affect Predicts Lower Satisfaction With Future Social Contact: A Time-Lagged Analysis Using Ecological Momentary Assessment

Published: February 2020

Abstract

Objectives
Prior research has linked subjective features of social situations with short-term changes in affect (e.g., across days, hours), but little is known about the directionality of such links. Our study examined the concurrent and lead–lag relationships between social contact satisfaction and affect in the flow of daily life.

Method
Using ecological momentary assessment (EMA), wherein 78 late-middle-aged and older adults reported on 2,739 social contacts (average 5.02 per day, SD = 2.95) across seven consecutive days, we examined how the level of social contact satisfaction was concurrently and prospectively associated with affect (high-arousal and low-arousal positive affect [PA], high-arousal and low-arousal negative affect [NA]).

Results
Higher contact satisfaction was concurrently associated with more high- and low-arousal PA and less high- and low-arousal NA. The influence of contact satisfaction remains for predicting greater low-arousal PA (quietness, calmness) during the next social contact. NA (either high- or low-arousal) predicted lower satisfaction during the next social contact, but such sustainable influence was not observed for PA.

Discussion
The study reveals a cycle in which elevated NA may trigger unsatisfactory social contact, which subsequently predicted less low-arousal PA such as quietness and calmness. Our study provided a more nuanced and differentiated picture of the temporal sequencing of everyday social contact and momentary affect. Practitioners may gain insights from our study into the development of just-in-time adaptive interventions that aim for the betterment of affective well-being in old age.
Accelerated full-waveform inversion using dynamic mini-batches

Published: February 2020

SUMMARYWe present an accelerated full-waveform inversion based on dynamic mini-batch optimization, which naturally exploits redundancies in observed data from different sources. The method rests on the selection of quasi-random subsets (mini-batches) of sources, used to approximate the misfit and the gradient of the complete data set. The size of the mini-batch is dynamically controlled by the desired quality of the gradient approximation. Within each mini-batch, redundancy is minimized by selecting sources with the largest angular differences between their respective gradients, and spatial coverage is maximized by selecting candidate events with Mitchell’s best-candidate algorithm. Information from sources not included in a specific mini-batch is incorporated into each gradient calculation through a quasi-Newton approximation of the Hessian, and a consistent misfit measure is achieved through the inclusion of a control group of sources. By design, the dynamic mini-batch approach has several main advantages: (1) The use of mini-batches with adaptive size ensures that an optimally small number of sources is used in each iteration, thus potentially leading to significant computational savings; (2) curvature information is accumulated and exploited during the inversion, using a randomized quasi-Newton method; (3) new data can be incorporated without the need to re-invert the complete data set, thereby enabling an evolutionary mode of full-waveform inversion. We illustrate our method using synthetic and real-data inversions for upper-mantle structure beneath the African Plate. In these specific examples, the dynamic mini-batch approach requires around 20 per cent of the computational resources in order to achieve data and model misfits that are comparable to those achieved by a standard full-waveform inversion where all sources are used in each iteration.

Published: February 2020

Abstract
How genome-wide association studies-identified single-nucleotide polymorphisms (SNPs) affect remote genes remains unknown. Expression quantitative trait locus (eQTL) association meta-analysis on 496 prostate tumor and 602 normal prostate samples with 117 SNPs revealed novel cis-eQTLs and trans-eQTLs. Mediation testing and colocalization analysis demonstrate that MSMB is a cis-acting mediator for SNHG11 (P &lt; 0.01). Removing rs10993994 in LNCaP cell lines by CRISPR/Cas9 editing shows that the C-allele corresponds with an over 100-fold increase in MSMB expression and 5-fold increase in SNHG11 compared with the T-allele. Colocalization analysis confirmed that the same set of SNPs associated with MSMB expression is associated with SNHG11 expression (posterior probability of shared variants is 66.6% in tumor and 91.4% in benign). These analyses further demonstrate variants driving MSMB expression differ in tumor and normal, suggesting regulatory network rewiring during tumorigenesis.

Abstract

Objectives
To provide an overview of the three major deadly coronaviruses and identify areas for improvement of future preparedness plans, as well as provide a critical assessment of the risk factors and actionable items for stopping their spread, utilizing lessons learned from the first two deadly coronavirus outbreaks, as well as initial reports from the current novel coronavirus (COVID-19) epidemic in Wuhan, China.

Methods
Utilizing the Centers for Disease Control and Prevention (CDC, USA) website, and a comprehensive review of PubMed literature, we obtained information regarding clinical signs and symptoms, treatment and diagnosis, transmission methods, protection methods and risk factors for Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS) and COVID-19. Comparisons between the viruses were made.

Results
Inadequate risk assessment regarding the urgency of the situation, and limited reporting on the virus within China has, in part, led to the rapid spread of COVID-19 throughout mainland China and into proximal and distant countries. Compared with SARS and MERS, COVID-19 has spread more rapidly, due in part to increased globalization and the focus of the epidemic. Wuhan, China is a large hub connecting the North, South, East and West of China via railways and a major international airport. The availability of connecting flights, the timing of the outbreak during the Chinese (Lunar) New Year, and the massive rail transit hub located in Wuhan has enabled the virus to perforate throughout China, and eventually, globally.

Conclusions
We conclude that we did not learn from the two prior epidemics of coronavirus and were ill-prepared to deal with the challenges the COVID-19 epidemic has posed. Future research should attempt to address the uses and implications of internet of things (IoT) technologies for mapping the spread of infection.

Authors: Zhao Ying , Zhao Jun 
Published: February 2020

AbstractThis study concentrates on the problem of $H_\infty $ output tracking bumpless transfer control for a category of switched linear systems (SLSs). The $H_\infty $ output tracking bumpless transfer control problem is to ensure the SLSs to satisfy the bumpless transfer performance and the $H_\infty $ output tracking properties by co-design of a switching rule and a series of controllers. Firstly, a concept of the bumpless transfer performance for a system in this class is presented. Then, via a Lyapunov function scheme, criteria guaranteeing the bumpless transfer performance and the $H_\infty $ output tracking properties are established. The criteria allow the problem of the $H_\infty $ output tracking bumpless transfer control for subsystems is unsolvable. Finally, an example of controlling a turbofan model is offered for the verification on the effectiveness of the presented control strategy.

Published: February 2020

Abstract

Objectives
To assess associations between polymorphisms within genes encoding proximal tubule transporters implicated in tenofovir renal clearance and kidney tubular dysfunction (KTD), chronic kidney disease (CKD) and individual biochemical parameters.

Patients and methods
The study included a cohort of HIV-positive Ghanaians receiving regimens containing tenofovir disoproxil fumarate (n = 66) for at least 6 months prior to study enrolment. SNPs in ABCC10, ABCC2 and ABCC4 were selected for analysis based on previous published associations. All SNPs were genotyped by real-time PCR allelic discrimination. Creatinine clearance (CLCR), serum and urine creatinine concentrations and biochemical measures of KTD were assessed. Statistical significance was determined through univariate linear or binary logistical regression (P ≤ 0.05).

Results
None of the SNPs evaluated was associated with CKD or KTD. A trend between body weight and higher incidence of CKD (P = 0.012, OR = 0.9) was observed. ABCC10 2843T&gt;C (rs2125739) was significantly associated with lower log10 baseline creatinine (P = 0.001, β= −0.4), higher baseline CLCR (P = 0.008, β = 65.2) and lower CLCR after 1 year (P = 0.024, β= −26.6).

Conclusions
This study demonstrates an association of ABCC10 rs2125739 with indicators of declining renal function and builds on current knowledge of this interaction within a Ghanaian cohort.

Published: February 2020

Abstract
A modification of a rapid and inexpensive multiresidue method for determination of pesticides in fruits and vegetables (QuEChERS method) is presented. Samples were extracted by shaking with acetic acidacetonitrile (1 + 99). Water was removed by liquidliquid partitioning with magnesium sulfate and sodium acetate. The extract was subjected to a single solid-phase extraction (SPE) column cleanup, which produced a cleaner extract than did the dispersive SPE cleanup used in the original QuEChERS method. Recovery data were obtained for 316 pesticide residues, at levels ranging from 20 ppb to 1.0 ppm. Data were provided by 3 different laboratories. The modified QuEChERS method resulted in a 65 reduction in solvent usage, when compared with the traditional multiresidue methods previously used in our laboratories.
Optimization of Hydrophilic Interaction Liquid Chromatography/Mass Spectrometry and Development of Solid-Phase Extraction for the Determination of Paralytic Shellfish Poisoning Toxins

Published: February 2020

Abstract
The combination of hydrophilic interaction liquid chromatography (HILIC) and liquid chromatography/mass spectrometry (LC/MS) for the determination of paralytic shellfish poisoning (PSP) toxins has been proposed for use in routine monitoring of shellfish. In this study, methods for the detection of multiple PSP toxins [saxitoxin (STX), neosaxitoxin (NEO), decarbamoyl saxitoxin (dcSTX), decarbamoyl neosaxitoxin (dcNEO), gonyautoxins 15 (GTX1, GTX2, GTX3, GTX4, GTX5), decarbamoyl gonyautoxins (dcGTX2 and dcGTX3), and the N-sulfocarbamoyl C toxins (C1 and C2)] were optimized using single (MS) and triple quadrupole (MS/MS) instruments. Chromatographic separation of the toxins was achieved by using a TSK-gel Amide-80 analytical column, although superior chromatography was observed through application of a ZIC-HILIC column. Preparative procedures used to clean up shellfish extracts and concentrate PSP toxins prior to analysis were investigated. The capacity of computationally designed polymeric (CDP) materials and HILIC solid-phase extraction (SPE) cartridges to retain highly polar PSP toxins was explored. Three CDP materials and 2 HILIC cartridges were assessed for the extraction of PSP toxins from aqueous solution. Screening of the CDPs showed that all tested polymers adsorbed PSP toxins. A variety of elution procedures were examined, with dilute 0.01 acetic acid providing optimum recovery from a CDP based on 2-(trifluoromethyl)acrylic acid as the monomer. ZIC-HILIC SPE cartridges were superior to the PolyLC equivalent, with recoveries ranging from 70 to 112 (ZIC-HILIC) and 0 to 90 (PolyLC) depending on the PSP toxin. It is proposed that optimized SPE and HILIC-MS methods can be applied for the quantitative determination of PSP toxins in shellfish.

Published: February 2020

Abstract
An immunoaffinity chromatographic method was developed for the purification of 9 sulfonamides (sulfamethazine, sulfadimethoxine, sulfamerazine, sulfathiazole, sulfamethoxazole, sulfamethizole, sulfadiazine, sulfamonomethoxine, and sulfapyridine) from chicken tissue (muscle and liver) samples. Two monoclonal antibodies (antisulfamethazine and antisulfamethoxazole) were simultaneously covalently coupled to CNBr-activated Sepharose 4B for the preparation of a re-usable immunoaffinity column. After extraction with methanolwater and purification by immunoaffinity column, the sulfonamides were determined by reversed-phase liquid chromatography and UV detection at 270 nm. The recoveries for each drug at fortification levels of 1050 ng/g ranged from 74.1 to 108.9 with relative standard deviations from 1.9 to 11.5. The limits of detection were 2 ng/g for each drug.

Published: February 2020

Abstract
An efficient method was developed for simultaneous determination of 13 quinolonesnamely, enoaxacin (ENO), marbofloxacin (MAR), ciprofloxacin (CIP), norfloxacin (NOR), ofloxacin (OFL), pefloxacin methanesulfonate (PEF), danofloxacin (DAN), enrofloxacin (ENR), lomefloxacin (LOM), difloxacin (DIF), sarafloxacin (SAR), oxolinic acid (OXO), and flumequine (FLU)in eggs by column liquid chromatography/electrospray ionization-tandem mass spectrometry. Samples were extracted with a phosphoric acidphosphate buffer followed by purification with a solid-phase extraction cartridge. Recoveries for the 13 quinolones were 6793 with intraday and interday coefficients of variation ranging from 4 to 9 and 2 to 18, respectively. The limit of determination was 0.05 g/kg for OXO and FLU; 0.1 g/kg for MAR, OFL, CIP, LOM, DAN, SAR, DIF, NOR, and ENR; and 0.2 g/kg for ENO and PEF. The method was also applied to study the depletion of PEF in eggs. The concentration of PEF increased and reached a maximum value on the third day, and then decreased rapidly until it could not be detected on day 32; its metabolite NOR was detectable on the second day, and then reached a maximum on the sixth day, after which it could not be detected until day 15.
Optimizing design to estimate genetic correlations between environments with common environmental effects
Authors: Lozano-Jaramillo Maria , Komen Hans , Wientjes Yvonne C J , Mulder Han A , Bastiaansen John W M 
Published: February 2020

Abstract
Breeding programs for different species aim to improve performance by testing members of full-sib (FS) and half-sib (HS) families in different environments. When genotypes respond differently to changes in the environment, this is defined as genotype by environment (G × E) interaction. The presence of common environmental effects within families generates covariance between siblings, and these effects should be taken into account when estimating a genetic correlation. Therefore, an optimal design should be established to accurately estimate the genetic correlation between environments in the presence of common environmental effects. We used stochastic simulation to find the optimal population structure using a combination of FS and HS groups with different levels of common environmental effects. Results show that in a population with a constant population size of 2,000 individuals per environment, ignoring common environmental effects when they are present in the population will lead to an upward bias in the estimated genetic correlation of on average 0.3 when the true genetic correlation is 0.5. When no common environmental effects are present in the population, the lowest standard error (SE) of the estimated genetic correlation was observed with a mating ratio of one dam per sire, and 10 offspring per sire per environment. When common environmental effects are present in the population and are included in the model, the lowest SE is obtained with mating ratios of at least 5 dams per sire and with a minimum number of 10 offspring per sire per environment. We recommend that studies that aim to estimate the magnitude of G × E in pigs, chicken, and fish should acknowledge the potential presence of common environmental effects and adjust the mating ratio accordingly.
