Published: September 2017

Background:
Because achalasia subtype is associated with therapeutic response, it is possible that regional differences in subtype distribution could lead to differences in therapeutic outcomes.

Study Question:
We aimed to evaluate and compare high-resolution manometry (HRM) profiles among the different subtypes of achalasia and to elucidate predictive factors associated with treatment outcomes.

Study Design:
Patients who were diagnosed with achalasia using HRM at 4 Korean university hospitals were retrospectively identified and analyzed. Sixty-four patients with untreated achalasia were divided into 3 subtypes using the Chicago classification system.

Measures and Outcomes:
Clinical characteristics, manometric features, and treatment outcomes were compared.

Results:
Among 64 patients diagnosed with achalasia, 31 patients were classified as type I, 27 as type II, and 6 as type III. Regarding HRM parameters, there were statistically significant differences in basal lower esophageal sphincter pressure, 4-second-integrated relaxation pressure, residual upper esophageal sphincter pressure, body amplitude, and maximal intrabolus pressure between subtypes. Regarding therapeutic outcome, type II patients (overall success rate of 80.0%) were more likely to respond than type I (55.2%) or type III (33.2%) patients. Multivariate analysis demonstrated that achalasia subtype (type I vs. III, P = 0.072; type II vs. III, P = 0.005), therapeutic modality (dilation vs. pharmacologic, P = 0.013; laparoscopic Heller's myotomy vs. pharmacologic, P = 0.006), and HRM-measured esophageal length (<27.5 vs. ≥27.5 cm, P = 0.014) are independent predictive factors for therapeutic failure.

Conclusions:
Patients with type II achalasia had better treatment outcomes than patients with other achalasia subtypes. Achalasia subtype, therapeutic modality, and esophageal length are independent predictive factors of therapeutic outcome.
Typologies for Restructuring Relationships in Cancer Survivorship
Authors: Henshall Catherine L. , Greenfield Sheila M. , Gale Nicola K. 
Published: September 2017

Background
Cancer survivors with good social support are generally more motivated to undertake self-management behaviors and make lifestyle changes. However, the impact of changes in social support over time, from prediagnosis through treatment and into survivorship, on the health and recovery of cancer survivors with a range of cancer diagnoses has not been explored.

Objective
The aim of this study was to examine how temporal changes in social support offered to cancer survivors by family and friends influence their engagement with self-management practices and adaptation to lifestyle changes.

Methods
The interview study took place in a teaching hospital in the West Midlands, United Kingdom. Forty participants were purposively sampled. A narrative approach to data collection was chosen, and data were thematically analyzed.

Results
Six typologies of restructuring relationships postcancer were identified. A greater understanding of the changes to social relationships that a cancer diagnosis can incur and the impact of this on people's outlook and ability to self-manage was developed.

Conclusion
The restructuring of social relationships by cancer survivors over time can impact their outlook and ability to self-manage in survivorship, shaping their engagement with health promoting activities and reconciling cancer within the wider context of their lives.

Implications for Practice
Appropriate clinical nursing processes and tailored interventions are required to support cancer survivors and promote engagement with self-management practices. Nurses are a vital component of the social support that enables patients to make the best health and lifestyle choices available to them.

Published: September 2017

Abstract
A new generation of veterans from Iraq/Afghanistan wars is seeking psychotropic pharmacotherapy for posttraumatic stress disorder (PTSD) from the Veterans Health Administration, but little is known about differences in prescribing practices between this group and Vietnam era veterans with the same diagnosis. The Veterans Health Administration administrative data for fiscal year 2012 were used to compare prescribing for 155,631 Iraq/Afghanistan veterans and for 327,634 Vietnam era veterans diagnosed with PTSD. The proportion of veterans who were prescribed psychotropic medications (altogether and within five of seven medication classes) were not substantially different between veteran groups. Iraq/Afghanistan veterans were more frequently prescribed prazosin (p < 0.0001, relative risk = 1.51). However, the number of prescriptions for anxiolytics/sedatives/hypnotics as well as prazosin and opiates filled by this younger group was lower by a small magnitude (Cohen's d < 0.2). Iraq/Afghanistan veterans have good access to psychopharmacological treatment for PTSD but fill somewhat fewer prescriptions than Vietnam era veterans.

AbstractIntroduction:Chronic low back pain (LBP) is a major cause of disability; early diagnosis and stratification of care remain challenges.Objectives:This article describes the development of a screening tool for the 1-year prognosis of patients with high chronic LBP risk (risk stratification index) and for treatment allocation according to treatment-modifiable yellow flag indicators (risk prevention indices, RPI-S).Methods:Screening tools were derived from a multicentre longitudinal study (n = 1071, age >18, intermittent LBP). The greatest prognostic predictors of 4 flag domains (“pain,” “distress,” “social-environment,” “medical care-environment”) were determined using least absolute shrinkage and selection operator regression analysis. Internal validity and prognosis error were evaluated after 1-year follow-up. Receiver operating characteristic curves for discrimination (area under the curve) and cutoff values were determined.Results:The risk stratification index identified persons with increased risk of chronic LBP and accurately estimated expected pain intensity and disability on the Pain Grade Questionnaire (0–100 points) up to 1 year later with an average prognosis error of 15 points. In addition, 3-risk classes were discerned with an accuracy of area under the curve = 0.74 (95% confidence interval 0.63–0.85). The RPI-S also distinguished persons with potentially modifiable prognostic indicators from 4 flag domains and stratified allocation to biopsychosocial treatments accordingly.Conclusion:The screening tools, developed in compliance with the PROGRESS and TRIPOD statements, revealed good validation and prognostic strength. These tools improve on existing screening tools because of their utility for secondary preventions, incorporation of exercise effect modifiers, exact pain estimations, and personalized allocation to multimodal treatments.

Published: September 2017

Introduction
The risk of incomplete bladder evacuation requiring catheterization after intravesical onabotulinumtoxinA (BoNT-A) is well established. However, the rates reported in the literature are highly variable and low overall in clinical trials. We attempt to evaluate the rate of symptomatic acute urinary retention requiring catheterization after initial BoNT-A in a private practice setting of patients with idiopathic overactive bladder.

Methods
We performed a retrospective study from 2010 to 2014 for patients with idiopathic overactive bladder undergoing their first BoNT-A. Demographic information recorded included age, sex, presence of diabetes, baseline postvoid residual (PVR), presence of urodynamic detrusor overactivity, bladder capacity, peak flow rate (Q
max), BoNT-A unit dose, and carrier volume. Urinary retention was defined as those patients who were symptomatic and required catheterization for a PVR of 200 mL or greater.

Results
Of 103 patients who received BoNT-A, 21 (20.3%) developed symptomatic retention requiring catheterization. There was no difference in baseline characteristics, preoperative PVR, and units injected (all P > 0.05). The retention group had a higher rate of bacteriuria and symptomatic urinary tract infection (all P < 0.05). Despite developing symptomatic retention requiring performance of catheterization, 47% of these patients continued with a subsequent injection of BoNT-A.

Conclusions
The need for catheterization after initial delivery of intravescial BoNT-A is an adverse event that seems to be higher in our clinical practice than seen in clinical trials. This information will be critical in order to properly counsel our future patients about the risks and benefits of this therapy.

Compliance with Ethical StandardsOtolith analysis was funded by a RAC grant from the University of New Mexico, USA. The Government of Chile supported the drafting of this document with a CONICYT Doctoral Fellowship to D. Alò in 2015 and to C. Correa through grants CONICYT-PAI N°82130009, and FONDECYT-Iniciación en la Investigación N°11150990.All applicable international, national, and/or institutional guidelines for the care and use of animals were followed. Specimens were collected under permits No. 3587, 29 December 2006, and No. 2886, 4 November 2008 (amendment No. 602, 12 February 2009) granted by the Chilean Subsecretary of Fishing to C. Correa. The McGill University Animal Care Committee (UACC), Animal Use Protocol No. 5291, approved use and handling of animals.AbstractCoastal habitats in Chile are hypothesized to support a number of diadromous fishes. The objective of this study was to document migratory life histories of native galaxiids and introduced salmonids from a wide latitudinal range in Chilean Patagonia (39-48°S). Otolith microchemistry data were analysed using a recursive partitioning approach to test for diadromy. Based on annular analysis of Sr:Ca ratios, a diadromous life history was detected for populations of nativeAplochiton taeniatus, A. marinus, andGalaxias maculatus. Lifetime residency in freshwater was suggested for populations ofA. zebraandG. platei. Among introduced salmonids, populations ofOncorhynchus tshawytschaandO. kisutchexhibited anadromous migratory patterns, whereas the population ofO. mykissscreened appeared restricted to freshwater.Salmo truttaexhibited variable habitat use consistent with establishment of an ocean-type life history in some populations. The capacity and geographic scope of hydropower development is increasing and may disrupt migratory routes of diadromous fishes. Identification of diadromous species is a critical first step for preventing their loss due to hydropower development.

AbstractThis report details current seasonal influenza circulation patterns as of Sep 2017 and makes projections up to Sep 2018 to coincide with selection of the 2018 Southern Hemisphere vaccine strain. This is not meant as a comprehensive report, but is instead intended as particular observations that we’ve made that may be of relevance. Please also note that observed patterns reflect the GISAID database and may not be entirely representative of underlying dynamics. All analyses are based on the nextflu pipeline [1] with continual updates posted tonextflu.org.A/H3N2H3N2 continues to diversify with many coexisting clades, all of which carry several amino acid mutations at previously characterized epitope sites. The majority of viruses fall into the 3c2.a clade which has been dominating globally for>3 years, but 3c3.a viruses continue to persist. The common ancestor of circulating H3N2 viruses is now more than 5 years old, which is rare for H3N2. Despite extensive genetic diversity, serological assays suggest limited, but non-zero, antigenic evolution. We expect multiple competing clades within 3c2.a to persist into the future with no clear immediate winner.A/H1N1pdmA clade comprising mutations S74R and I295V has recently risen to>60% global frequency. Although it shows no antigenic distinction by ferret HI data, the rapidity of its rise suggests a selective origin.B/VicA clade with a two amino acid deletion 162-/163-has altered serological properties and is increasing in frequency, albeit slowly. Two other clades (carrying mutations K209N and V87A/I175V) have increased in frequency moderately.B/YamA clade comprising M251V within clade 3 viruses continues to dominate. The is little genetic differentiation within this clade and no evidence of antigenic evolution.
Overlooked biodiversity loss in Amazonian smallholder agriculture
Authors: Socolar Jacob B. , Valderrama Sandoval Elvis H. , Wilcove David S. 
Published: September 2017

ABSTRACTDiversified smallholder agriculture is the main human land-use affecting the western Amazon, home to the world’s richest terrestrial biota, but the scant available data to date have suggested that the biodiversity impacts of this land-use are small. Here, we present comprehensive surveys of birds and trees in primary forest and smallholder agricultural mosaics in northern Peru. These surveys reveal substantial biodiversity losses that have been overlooked by other studies. Avian biodiversity losses arise primarily from biotic homogenization across infrequently surveyed forest habitats (a loss of beta-diversity). Furthermore, tree species richness declines much more steeply than bird richness. Statistical modeling of local habitat features that allow forest-associated species to persist in the smallholder mosaic strongly suggests that our results represent a best-case scenario for Amazonian agricultural biodiversity. We conclude that previous assessments of the biodiversity value of Amazonian smallholder agriculture have been overly optimistic because they are restricted to upland habitat, thereby missing losses in beta diversity; do not evaluate trees; and/or rely on generalizations from less speciose areas of the Neotropics, where habitat specialization amongst species is less prevalent. Smallholder agriculture will likely expand in western Amazonia due to infrastructure development, and it must be seen as a serious threat to the region’s biodiversity.
Fitness effects and transmission of phoretic nematodes of the burying beetle,Nicrophorus vespilloides
Authors: Wang Yin , Rozen Daniel E. 
Published: September 2017

AbstractNicrophorus vespilloidesis a cosmopolitan social beetle that rears its offspring on decomposing carrion. Wild beetles are frequently associated with two types of macrobial symbionts, mites and nematodes.Although these organisms are believed to be phoretic commensals that harmlessly use beetles as a means of transfer between carcasses, the role of these symbionts onN. vespilloidesfitness is poorly understood. Here we show that nematodes have significant negative effects on beetle fitness across a range of worm densities and also quantify the density-dependent transmission of worms between mating individuals and from parents to offspring.Using field-caught beetles, we provide the first report of a new nematode symbiont inN. vespilloides, most closely related toRhabditoides regina, and show that worm densities are highly variable across individuals isolated from nature but do not differ between males and females. Next, by inoculating mating females with increasing densities of nematodes, we show that worm infections significantly reduce brood size, larval survival and larval mass, and also eliminate the trade-off between brood size and larval mass. Finally, we show that nematodes are efficiently transmitted between mating individuals and from mothers to larvae, directly and indirectly via the carcass, and that worms persist through pupation.These results show that the phoretic nematodeR. reginacan be highly parasitic to burying beetles but can nevertheless persist because of efficient mechanisms of intersexual and intergenerational transmission.Phoretic species are exceptionally common and may cause significant harm to their hosts, even though they rely on these larger species for transmission to new resources. However, this harm may be inevitable and unavoidable if transmission of phoretic symbionts requires nematode proliferation. It will be important to determine the generality of our result for other phoretic associates of animals.

ABSTRACTThe progression of chronic obstructive pulmonary disease (COPD) is associated with marked alterations in circulating immune cell populations, but no studies have characterized alterations in these cell types across the full spectrum of lung function impairment in current and former smokers. In 6,299 subjects from the COPDGene and ECLIPSE studies, we related Coulter blood counts and proportions to cross-sectional FEV1adjusting for current smoking status. We also related cell count measures to three-year change in FEV1in ECLIPSE subjects. In a subset of subjects with blood gene expression data, we used cell type deconvolution methods to infer the proportions of immune cell subpopulations, and we related these to COPD clinical status. We observed that FEV1levels are positively correlated with lymphocytes and negatively correlated with myeloid populations such as neutrophils and monocytes. In multivariate models, absolute cell counts and proportions were associated with cross-sectional FEV1, and lymphocytes, monocytes, and eosinophil counts were predictive of three-year change in lung function. Using cell type deconvolution to study immune cell subpopulations, we observed that subjects with COPD had a lower proportion of CD4+ resting memory cells and naive B cells compared to non-COPD smokers. Alterations in circulating immune cells in COPD support a mixed pattern of lymphocyte suppression and an enhanced myeloid cell immune response. Cell counts and proportions contribute independent information to models predicting lung function suggesting a critical role for immune response in long-term COPD outcomes. Cell type deconvolution is a promising method for immunophenotyping in large cohorts.
Extreme heterogeneity of influenza virus infection in single cells
Authors: Russell Alistair B. , Trapnell Cole , Bloom Jesse D. 
Published: September 2017

AbstractViral infection can dramatically alter a cell’s transcriptome. However, these changes have mostly been studied by bulk measurements on many cells. Here we use single-cell mRNA sequencing to examine the transcriptional consequences of Influenza virus infection. We 1nd extremely wide cell-to-cell variation in production of viral gene transcripts – viral transcripts compose less than a percent of total mRNA in many infected cells, but a few cells derive over half their mRNA from virus. Some infected cells fail to express at least one viral gene, and this gene absence partially explains variation in viral transcriptional load. Despite variation in total viral load, the relative abundances of viral mRNAs are fairly consistent across infected cells. Activation of innate immune pathways is rare, but some cellular genes co-vary in abundance with the amount of viral mRNA. Overall, our results highlight the complexity of viral infection at the level of single cells.

AbstractMind wandering represents the human capacity for internally focussed thought, and relies upon the brain’s default network and its interactions with attentional networks. Studies have characterised mind wandering in healthy people, yet there is limited understanding of how this capacity is affected in clinical populations. This study used a validated thought-sampling task to probe mind wandering capacity in two neurodegenerative disorders: behavioural variant frontotemporal dementia (bvFTD; n=35) and Alzheimer’s disease (AD; n=24), compared to older controls (n=37). These patient groups were selected due to canonical structural and functional changes across sites of the default and frontoparietal networks, and well-defined impairments in cognitive processes that support mind wandering. Relative to controls, bvFTD patients displayed significantly reduced mind wandering capacity, offset by a significant increase in stimulus-bound thought. In contrast, AD patients demonstrated comparable levels of mind wandering to controls, in the context of a relatively subtle shift towards stimulus-/task-related forms of thought. In the patient groups, mind wandering was associated with grey matter integrity in the hippocampus/parahippocampus, striatum, insula and orbitofrontal cortex. Resting state functional connectivity revealed associations between mind wandering capacity and connectivity within and between regions of the frontoparietal and default networks, with distinct patterns evident in patients vs. controls. These findings support a relationship between altered mind wandering capacity in neurodegenerative disorders, and structural and functional integrity of the default and frontoparietal networks. This study highlights a dimension of cognitive dysfunction not well documented in neurodegenerative disorders, and validates current models of mind wandering in a clinical population.Significance statementHumans spend much of their waking life engaged in mind wandering. Underlying brain systems supporting this complex ability have been established in healthy individuals, yet it remains unclear how mind wandering is altered in neuropsychiatric populations. We reveal changes in the thought profiles elicited during periods of low cognitive demand in dementia, resulting in reduced mind wandering and an increased propensity towards stimulus-bound thought. These altered thought profiles were associated with structural and functional brain changes in the hippocampus, default and frontoparietal networks; key regions implicated in internal mentation in healthy individuals. Our findings provide a unique clinical validation of current theoretical models of mind wandering, and reveal a dimension of cognitive dysfunction that has received scant attention in dementia.
