A Targeted Quantitative Proteomic Approach Assesses the Reprogramming of Small GTPases during Melanoma Metastasis
Authors: Huang Ming , Qi Tianyu F. , Li Lin , Zhang Gao , Wang Yinsheng 
Published: August 2018

Abstract
Small GTPases of the Ras superfamily are master regulators of intracellular trafficking and constitute essential signaling components in all eukaryotes. Aberrant small GTPase signaling is associated with a wide spectrum of human diseases, including cancer. Here, we developed a high-throughput, multiple reaction monitoring–based workflow, coupled with stable isotope labeling by amino acids in cell culture, for targeted quantification of approximately 100 small GTPases in cultured human cells. Using this method, we investigated the differential expression of small GTPases in three pairs of primary and metastatic melanoma cell lines. Bioinformatic analyses of The Cancer Genome Atlas data and other publicly available data as well as cell-based assays revealed previously unrecognized roles of RAB38 in promoting melanoma metastasis. Diminished promoter methylation and the subsequent augmented binding of transcription factor MITF contributed to elevated expression of RAB38 gene in metastatic versus primary melanoma cells. Moreover, RAB38 promoted invasion of cultured melanoma cells by modulating the expression and activities of matrix metalloproteinases-2 and -9. Together, these data establish a novel targeted proteomic method for interrogating the small GTPase proteome in human cells and identify epigenetic reactivation of RAB38 as a contributing factor to metastatic transformation in melanoma.
Significance: A novel quantitative proteomic method leads to the discovery of RAB38 as a new driver of metastasis in melanoma. Cancer Res; 78(18); 5431–45. ©2018 AACR.

Abstract

Adenomatous Polyposis Coli (APC) gene mutations are responsible for the onset of familial adenomatous polyposis (FAP) and sporadic colorectal cancer and have been associated with miRNAs dysregulation. The capacity of miR-155, a cancer-related miRNA, to target components of the WNT/β-CATENIN pathway suggests that APC gene mutations, controlling miRNAs expression, may critically regulate WNT/β-CATENIN signaling. To this end, APC gene target sequencing was performed on colonic adenomatous polyps and paired normal mucosa clinical specimens from FAP patients (n = 9) to elucidate the role of miR-155-5p in APC-mutant setting. The expression of selected miRNAs and WNT/β-CATENIN signaling components was characterized in FAP patients and non-FAP control subjects (n = 5). miR-155-5p expression and functional effects on WNT cascade, cell survival, growth, and apoptosis were investigated in different colorectal cancer cell lines. A somatic second hit in the APC gene was found in adenomatous polyps from 6 of 9 FAP patients. Heterozygous APC gene mutations in FAP patients were associated with altered expression of candidate miRNAs and increased levels of AXIN1 and AXIN2 mRNAs. miR-155-5p was downregulated in FAP patients and in the APC and β-CATENIN–mutant colorectal cancer cell lines, and critically regulates WNT/β-CATENIN cascade by targeting both AXIN1 and TCF4. Importantly, miR-155-5p may sustain long-term WNT/β-CATENIN activation in colorectal cancer cells upon WNT3A stimulation.

Implications:
This study supports a key role of miR-155-5p in modulating WNT/β-CATENIN signaling in colorectal cancer and unravels a new mechanism for AXIN1 regulation which represents a potential therapeutic target in specific tumor subtypes.
A Review of the Imaging Techniques for Measuring Kidney and Cyst Volume in Establishing Autosomal Dominant Polycystic Kidney Disease Progression
Authors: Magistroni Riccardo , Corsi Cristiana , Martí Teresa , Torra Roser 
Published: August 2018

<b><i>Background:</i></b> Autosomal dominant polycystic kidney disease (ADPKD) is the commonest inherited renal disorder; it is defined by progressive renal cyst formation and subsequent renal enlargement that leads to end-stage renal disease. Until recently, only symptomatic treatments for ADPKD existed. However, therapies that address the underlying pathophysiology of ADPKD are now available and accurate identification of the rate of disease progression is essential. <b><i>Summary:</i></b> Published data on the different imaging modalities for measuring kidney and cyst volumes in ADPKD are reviewed. The advantages and drawbacks of the different techniques for calculating kidney volume from renal imaging are also examined, including the use of manual planimetry, stereology, and the ellipsoid equation, as well as the prospect of semi- and fully automatic techniques. The translation of these approaches into clinical practice and their role in informing treatment decisions is discussed. <b><i>Key Messages:</i></b> These new therapies require the accurate monitoring of disease progression, which along with diagnosis and prognosis, relies on the effective use of renal imaging techniques. There is growing support for the use of total kidney volume as a measure of cyst burden and as a prognostic predictor of renal function in ADPKD, showing promise as a marker of disease progression.
Public Participation in China’s Water Governance

Published: August 2018

Abstract
This article analyses the role of public participation in China’s water governance. First, it provides an overview of the relevant international law provisions applicable to China. This is followed by an analysis of the implementation of these international obligations and their incorporation into China’s domestic water governance. The article demonstrates that the problem is not a lack of rules and regulations calling for public participation, but rather that these rules and regulations are often too vague to be meaningfully applied in practice. It is not always clear what type of public participation is called for, and which public should be invited to participate.
Using Lomb–Scargle Analysis to Derive Empirical Orthogonal Functions from Gappy Meteorological Data
Authors: Dupuis Christopher , Schumacher Courtney 
Published: August 2018

AbstractThe Lomb–Scargle discrete Fourier transform (LSDFT) is a well-known technique for analyzing time series. In this study, a solution for empirical orthogonal functions (EOFs) based on irregularly sampled data is derived from the LSDFT. It is demonstrated that this particular algorithm has no hard limit on its accuracy and yields results comparable to those of complex Hilbert EOF analysis. Two LSDFT algorithms are compared in terms of their performance in evaluating EOFs for precipitation observations from the Tropical Rainfall Measuring Mission satellite. Both are shown to be able to capture the pattern of the diurnal cycle of rainfall over the complex topography and diverse land cover of South America, and both also show other consistent features in the 0–12-day frequency band.

Published: August 2018

Background Apolipoprotein E-containing high-density lipoprotein shows antiatherogenic properties in vitro. There is a need for a homogeneous assay to determine the concentration of apolipoprotein E-containing high-density lipoprotein for in vivo studies. Methods In the proposed homogeneous assay, lipoproteins other than apolipoprotein E-containing high-density lipoprotein were eliminated in the first step. Apolipoprotein E-containing high-density lipoprotein-cholesterol was measured in the second step. The control study used a 13% polyethylene glycol precipitation assay (control assay). Results The homogeneous assay showed good performance in validation studies. In subjects with normal liver function ( n = 78), a significant correlation was found between the control assay and the homogeneous assay ( r = 0.824). Serum apolipoprotein E-containing high-density lipoprotein cholesterol concentrations, determined by the control assay and the homogeneous assay, respectively, were 0.05 (0.04–0.10) (median [25th–75th percentile]) mmol/L and 0.10 (0.06–0.13) mmol/L for healthy individuals ( n = 12), and 0.03 (0.01–0.13) mmol/L and 0.02 (0.01–0.02) mmol/L for patients with cholestasis ( n = 6). The results indicate that the homogeneous assay recovers cholesterol contained in physiological apolipoprotein E-containing high-density lipoprotein, but not in pathological apolipoprotein E-containing high-density lipoprotein from cholestatic patients. Conclusions The proposed two-step homogeneous assay enables selective measurement of physiological apolipoprotein E-containing high-density lipoprotein cholesterol in common autoanalysers. This assay might uncover a role for apolipoprotein E-containing high-density lipoprotein in physiological conditions.
Oxidative Stress and Preterm Birth: An Integrative Review
Authors: Moore Tiffany A. , Ahmad Iman M. , Zimmerman Matthew C. 
Published: August 2018

Background:A variety of methods and measures have been used to quantify oxidative stress in clinical studies related to preterm birth (PTB), and studies have reported conflicting findings. No integrative reviews have been conducted.Objective:To describe specific molecules used as markers of oxidative stress and methods to measure these molecules and to review the literature for associations between oxidative stress and PTB specific to these molecules.Method:Systematic literature searches were conducted in June 2015 and updated in 2017 in databases from the Biomedical Reference Collection: Basic Edition, including MEDLINE and clinicaltrials.gov . Articles were included if they described original research published after 2009 and compared PTB or preterm premature rupture of membranes with term birth (TB).Results:Abstracts ( n = 3,107) were reviewed for inclusion/exclusion criteria. Of these, 308 were full-text reviewed, and 30 articles were included in this review. All were identified as nonexperimental. The most common measurements of oxidative stress were quantification of total oxidant or antioxidant status or lipid peroxidation. Studies measuring reactive oxygen species or by-products of oxidative stress reported higher levels of these molecules for preterm specimens compared to TB specimens. Studies measuring antioxidants reported lower levels for these molecules in PTB specimens. Few of the studies had inconclusive findings.Discussion:Findings suggest that an imbalance between oxidants and antioxidants may be associated with PTB. The measurements and findings to date limit interpretation and understanding. Research using multidimensional methods and multidisciplinary teams are necessary to advance research and practice.

Published: August 2018

Background: Smoking has been associated with increased multiple sclerosis (MS) risk, disease worsening, and progression in MS patients. Furthermore, interactions between smoking and human leukocyte antigen (HLA) genes have been shown for MS risk. Recently, we found that smoking was associated with an increased relapse rate in interferon-beta-treated relapsing-remitting multiple sclerosis (RRMS) patients. Objectives: We examined the association between smoking and relapses in natalizumab-treated RRMS patients. Second, we investigated if an interaction between smoking and HLA-DRB1*15:01 or HLA-A*02:01 affected the number of relapses during treatment. Methods: In this observational cohort study, 355 natalizumab-treated RRMS patients were assessed. Prespecified criteria excluded 62 patients. Clinical data from the starting of treatment to the two-year follow-up visit were collected. Smoking status was obtained by a questionnaire survey. TaqMan allelic discrimination was used for genotyping of tag single-nucleotide polymorphisms (SNPs) for HLA-DRB1*15:01 and HLA-A*02:01. Negative binomial regression analysis was used to analyze the association between relapse rate and smoking intensity and HLA. Results: One pack of cigarettes (20 cigarettes) per day during natalizumab treatment increased the relapse rate during treatment with 38% (incidence rate ratio (IRR) = 1.38, 95% confidence interval (CI): 1.08–1.77, p = 0.01). No association or interaction was found between smoking and HLA-DRB1*15:01 or HLA-A*02:01, respectively. Conclusion: Smoking intensity was significantly associated with the number of relapses during natalizumab treatment.

Introduction In an ageing population, increasing chronic disease prevalence puts a high economic burden on society. Physical activity plays an important role in disease prevention and should therefore be promoted in the elderly. Methods In this study, a mobile health (mHealth) system was implemented in a care home setting to monitor and promote elderly peoples’ daily activity. The physical activity of 20 elderly people (8 female and 12 male, aged 81 ± 9 years old) was monitored over 10 weeks using the mHealth system, consisting of a smartphone and heart rate belt. Feedback on physical activity was provided weekly. A reference performance test battery derived from the Senior Fitness Test determined the participants’ physical fitness. Results Activity levels increased from week 1 onwards, peaking at week 5, and decreasing slightly until week 10. This illustrates that the use of mHealth and feedback on physical activity can motivate the elderly to become more active, but that the effect is transient without other incentives. Bio-data from the mHealth system were translated into a fitness score explaining 65% of the test battery’s variance. After separating the elderly into three groups depending on physical fitness determined from the test battery, classification based on the fitness score resulted in a correct classification rate of 67.3%. Discussion This study demonstrates that an mHealth system can be implemented in a care home setting to motivate activity of the elderly, and that the bio-data can be translated in a fitness score predicting the outcome of labour-intensive tests.

Published: August 2018

Background: The Internet has drastically changed how patients access health-related information. There are several ways the public can access online health-related information such as search engines, blogs, support groups, and webinars. A recent study found that 45% of orthopedic patients searched for information online regarding their injury. Also, 78% believed they had better understanding of their condition after visiting these websites; furthermore, 41% felt the Internet supplied them with questions and concerns to discuss with their physicians. The aim of our study is to evaluate the accuracy, quality, and readability of online available information using the search terms “ankle sprain” and “ankle instability.” Methods: Three search engines (Google, Bing, and Yahoo) were used to search for the terms “ankle sprain” and “ankle instability.” The first 25 websites from each search were collected. Each website was assessed for quality, accuracy, and readability by 3 orthopedic residents blinded to the search term used. Websites were also evaluated for commercial bias and whether written by physicians or not. Results: Twenty sites were identified using Google, 14 using Bing, and 3 using Yahoo while the remaining 19 appeared in multiple search engines. Sixty-nine percent of the websites (39/56) were written by physicians whereas only 21% (12/56) were associated with commercial bias. The mean quality and accuracy of the websites written above a seventh-grade level was statistically significantly higher than those at or below a seventh-grade level ( P = .01). The mean accuracy of websites written by physicians was not statistically different from those not written by physicians ( P = .055). Conclusion: The current study highlights the poor quality and accuracy of online information related to ankle sprains, especially those with commercial bias. Furthermore, although websites written by or under supervision of physicians were found to be of superior quality, a majority of sites were found to have an unacceptably high reading level. Level of Evidence: Level IV, case series.

Published: August 2018

Purpose: The purpose of this study was to determine the efficacy of pneumatic vitreolysis in the treatment of symptomatic focal vitreomacular traction (VMT). Methods: Patients choosing intravitreal gas injection as their preferred treatment for symptomatic VMT were invited to participate in this prospective study; 0.3 mL of perfluoropropane gas was injected. Optical coherence tomography was performed pre-and postprocedure to determine the proportion of eyes showing release of VMT. Results: Nine eyes of nine participants were included in the study, with a mean follow-up of 5.0±1.8 months. Gas injection resulted in the release of VMT in 7 of 9 eyes (78%) during the course of the study. Both eyes in which the VMT failed to release also showed an improvement in central macular anatomy. Mean visual acuity improved from logarithm of the minimum angle of resolution (logMAR) 0.33±0.14 (Snellen equivalent, ∼20/42) to logMAR 0.24±0.21 (Snellen, ∼20/35) at final follow-up ( P = .03); 8 of 9 patients (89%) reported a subjective improvement in their presenting symptoms and/or vision during the study period. The mean maximum foveal thickness of 480 ± 22 μm at baseline reduced to 282 ± 94 μm by the time of the final visit ( P = .002). Two patients had retinopexy for retinal breaks/suspect breaks. Conclusions: Pneumatic vitreolysis is an effective treatment for symptomatic VMT and may offer cost savings for patients and/or health services.
Changes in the use of the Mental Health Act 1983 in England 1984/85 to 2015/16
Authors: Keown Patrick , Murphy Hannah , McKenna Dannielle , McKinnon Iain 
Published: August 2018

BackgroundConcerns have been raised about the increase in the use of involuntary detentions under the Mental Health Act in England over a number of years, and whether this merits consideration of legislative change.AimsTo investigate changes in the rate of detentions under Part II (civil) and Part III (forensic) sections of the Mental Health Act in England between 1984 and 2016.MethodRetrospective analysis of data on involuntary detentions from the National Archives and NHS Digital. Rates per 100 000 population were calculated with percentage changes. The odds of being formally admitted to a National Health Service hospital compared with a private hospital were calculated for each year.ResultsRates of detention have at least trebled since the 1980s and doubled since the 1990s. This has been because of a rise in Part II (civil) sections. Although the overall rate of detentions under Part III (forensic) sections did not rise, transfers from prison increased and detentions by the courts reduced. The odds of being detained in a private hospital increased fivefold.ConclusionsThe move to community-based mental health services in England has paradoxically led to an increase in the number of people being detained in hospital each year, and in particular an inexorable rise in involuntary admissions. This is likely to be partly because of improved case finding with an increased focus on treatment and risk management, and partly because of changes in legislation. An increasing proportion of this government-funded care is being provided by private hospitals.Declaration of interestNone.

Published: August 2018

Purpose A joint data quality initiative between the Cancer Treatment Centers of America and the ASCO big data health technology platform CancerLinQ® was initiated to document and codify the steps taken to evaluate, stratify, and determine the potential effect of data elements used for electronic clinical quality measures as captured within structured fields in electronic health records. Methods The processes involved the identification of clinical concepts required in measure population criteria and then to map these to the corresponding components of the CancerLinQ data model. A quantitative assessment of mappings between electronic clinical quality measure clinical concepts and attributes from the CancerLinQ clinical database was performed. In parallel, a qualitative analysis of high-impact data elements from the Cancer Treatment Centers of America clinical measures was made using local, expert consensus. Results An impact assessment was derived using a count of the data elements across measures and the specific population criteria affected. Conclusion A list of putative high-impact data elements can provide guidance for clinicians to facilitate specific data element capture related to quality metrics in an electronic environment.
Age-Standardized Mortality Rates in the Caribbean: One Source, Three Different Interpretations
Authors: Wolf Nicholas G. , Morgan Camille , Flanigan John S. 
Published: August 2018

Purpose A recent publication in Morbidity and Mortality Weekly Report ( MMWR) provided the opportunity to calculate differences in published cancer mortality estimates for Caribbean jurisdictions from three organizations: MMWR, the International Agency for Research on Cancer, and the Institute for Health Metrics and Evaluation. This comparison study serves to educate end users of these data. Methods We downloaded the publicly available cancer mortality estimates for 15 jurisdictions and the United States from the three organizations. We compared reported age-standardized mortality rates for each jurisdiction and calculated the range among estimates for each jurisdiction. We repeated this analysis after applying the same world population standard to all estimates. Results For males, the ranges of the Caribbean estimates were between 49% (Grenada and Trinidad) and 201% (US Virgin Islands) of the MMWR value, with an average of 88%. For females, the ranges were between 15% (Trinidad) and 171% (US Virgin Islands) of the MMWR value, with an average of 64%. After all estimates were compared using the same population standard, the ranges of the Caribbean estimates for males were between 6% (Grenada) and 111% (US Virgin Islands) of the MMWR value, with an average of 34%. For females, the ranges were between 7% (Grenada) and 97% (US Virgin Islands), with an average of 28%. Conclusion The use of different standard populations complicates comparisons across organizations. Data modeling does not completely compensate for quality of source data, as our analysis demonstrated by the differences in mortality rates despite the good quality of the vital registration in the Caribbean.
