Understanding everyday life and mental health recovery through CHIME
Authors: Piat Myra , Seida Kimberly , Sabetti Judith 
Published: September 2017

Purpose
The purpose of this paper is to understand how daily life reflects the recovery journeys of individuals with serious mental illness (SMI) living independently in the community.

Design/methodology/approach
The go-along technique, which blends participant observation and interviewing, was used to gather data from 19 individuals with SMI living in supported housing. Data were analyzed through the CHIME framework of personal recovery, which includes social connectedness, hope and optimism, identity, meaning in life, and empowerment.

Findings
Applying the CHIME framework to qualitative data reveals the multiple ways in which everyday experiences, within and beyond formal mental healthcare environments, shapes personal recovery processes.

Research limitations/implications
Combining novel methods and conceptual frameworks to lived experiences sharpens extant knowledge of the active and non-linear aspects to personal recovery. The role of the researcher must be critically considered when using go-along methods.

Practical implications
Practitioners working with this population should account for the role of socially supportive and financially accessible spaces and activities that support the daily work of recovery beyond the context of formal care and services.

Originality/value
This study utilizes an innovative method to illustrate the crucial role of daily and seemingly banal experiences in fostering or hindering personal recovery processes. It is also the one of the first studies to comprehensively apply the CHIME framework to qualitative data in order to understand the recovery journeys of individuals with SMI living in supported housing.
Transforming followers into fans: a study of Chinese users of the WeChat Official Account
Authors: Guo Lingyun , Zhang Mingli , Kang Kai , Hu Mu 
Published: September 2017

Purpose
Drawing upon the social cognitive and customer engagement theories, the purpose of this paper is to investigate how individuals’ simple follow, purely aiming for information but with little contribution, could affect fans behavior and make them engage in company social network (CSN). The study identifies the impact of personal motivators (follower participation motivation), environmental antecedents (perception of information quality) and individual behavior (fan engagement behavior and stickiness) on CSNs and examines the interaction relationship between the follower participation motivation and perception of information quality.

Design/methodology/approach
Data collected from 392 valid questionnaires from WeChat Official Account users were analyzed by structural equation modeling.

Findings
Personal factor such as follower participation motivation (intrinsic and extrinsic motivator) was found to be significant predictor of fan engagement behavior. Environmental factor (perception of information quality: perceived usefulness as well as perceived entertainment) was a significant factor in determining followers’ proclivity to engage in CNSs. One significant interaction effect was found: the effect of perceived entertainment on fan engagement behavior was manifested to a greater extent when followers’ participation aimed for intrinsic motivator. The second interaction effect, between the extrinsic motivator and perceived usefulness, was also found to be statistically significant.

Originality/value
This study enriches and extends the studies on the theories of customer engagement and social cognitive theory. It applies the above theories to CSNs and advances CSNs research by taking into consideration both personal and environmental factors (follower participation motivation and perception of information quality), and the interaction effects of the two on individual behavior.

AbstractChitin and chitosan were extracted from all specimens of Type I and II two‐spotted field crickets (Gryllus bimaculatus) following chemical treatment with an acid and alkali. For chitin extraction, 2 N HCl and 1.25 N NaOH solutions were used to achieve demineralization and deproteinization, respectively. For chitosan extraction, 50 % NaOH (w/v) and 50 % NaOH (w/w) solutions were used to achieve deacetylation. Chitosan yielded from adult exoskeletons of G. bimaculatus in Test A of Type I was 1.76 and 8.40 % on a fresh weight (FW) and dry weight (DW) basis, respectively, after treatment with 50 % NaOH (w/v) at 95°C for 3 h. Furthermore, the chitosan yielded in Test D of Type II was 1.79 and 7.06 % on FW and DW basis, respectively, after treatment with 50 % NaOH (w/w) at 105°C for 3 h. The average yield of chitin and chitosan was 2.42 and 1.65 % on a FW basis, and 10.91 and 7.50 % on DW basis, respectively. The deacetylation (%) of chitosan extracted from adult exoskeletons in Tests A, B, C1, C2, D1, and D2 were 81.2 %, 14.5 %, 19.6 %, 90.7 %, 17.1 %, and 95.5 %, respectively. The viscosities of the chitosans extracted from adult exoskeletons in Tests A, C2, and D2 were 32.0, 21.6, and 62.4 cP (centi Poise), respectively. The molecular weight of chitosan from adult exoskeletons of G. bimaculatus was 308.3 kDa. Our results indicate that adult exoskeletons of G. bimaculatus could be used as a source of chitin and chitosan for use as functional additives in industrial animal feeds.

Published: September 2017

AbstractFungal endophytes can be part of the defensive system of plants against multiple pathogens by competing for resources, hyperparasitism or producing bioactive compounds with antimicrobial properties. There is an ever‐increasing interest for obtaining new and environmentally friendly products to use in the fight against pathogens. With this purpose, Byssochlamys spectabilis (anamorph Paecilomyces variotii), which is a fungal species that commonly occurs, was evaluated as an antagonistic organism towards three phytopathogens (Biscogniauxia mediterranea, Fusarium moniliforme and Phytophthora cinnamomi). First, an in vitro experiment was designed to test the effect that the endophyte filtrate had on the three pathogens. The endophyte filtrate decreased the radius growth rate of F. moniliforme by nearly 10%. Consequently, the antagonism between B. spectabilis and F. moniliforme was evaluated in Lolium rigidum plants under greenhouse conditions by means of co‐inoculations. The endophyte produced a decrease of 50–75% in the disease severity caused by the pathogen in the earliest infection stages. Crude extracts of B. spectabilis were obtained to determine the secondary metabolites responsible for such an effect. The bioactivity‐guided chromatography and HPLC‐MS (high performance liquid chromatography coupled with mass spectrometry) of the active fraction suggested that the antibiotic activity was caused by viriditoxin. In conclusion, the fungal endophyte B. spectabilis and/or its bioactive compounds showed antagonism towards several phytopathogens and deserves further study to investigate its actual potential for use as a biocontrol agent.
Optimal designs for minimising covariances among parameter estimators in a linear model
Authors: Mandal S. , Torsney B. , Chowdhury M. 
Published: September 2017

SummaryWe construct approximate optimal designs for minimising absolute covariances between least‐squares estimators of the parameters (or linear functions of the parameters) of a linear model, thereby rendering relevant parameter estimators approximately uncorrelated with each other. In particular, we consider first the case of the covariance between two linear combinations. We also consider the case of two such covariances. For this we first set up a compound optimisation problem which we transform to one of maximising two functions of the design weights simultaneously. The approaches are formulated for a general regression model and are explored through some examples including one practical problem arising in chemistry.
Joint estimation of multiple high‐dimensional Gaussian copula graphical models
Authors: He Yong , Zhang Xinsheng , Ji Jiadong , Liu Bin 
Published: September 2017

SummaryA joint estimation approach for multiple high‐dimensional Gaussian copula graphical models is proposed, which achieves estimation robustness by exploiting non‐parametric rank‐based correlation coefficient estimators. Although we focus on continuous data in this paper, the proposed method can be extended to deal with binary or mixed data. Based on a weighted minimisation problem, the estimators can be obtained by implementing second‐order cone programming. Theoretical properties of the procedure are investigated. We show that the proposed joint estimation procedure leads to a faster convergence rate than estimating the graphs individually. It is also shown that the proposed procedure achieves an exact graph structure recovery with probability tending to 1 under certain regularity conditions. Besides theoretical analysis, we conduct numerical simulations to compare the estimation performance and graph recovery performance of some state‐of‐the‐art methods including both joint estimation methods and estimation methods for individuals. The proposed method is then applied to a gene expression data set, which illustrates its practical usefulness.

Published: September 2017

AbstractBuffalo milk represents an indispensable source of nourishment in many parts of the world and it is the second most consumed milk worldwide. Buffalo milk is actually used for the production of many dairy products such as pasteurized or concentrated milk, butter, yogurt, ice‐cream, dehydrated milk products and cheeses. Due to its high nutritional value and the presence of natural bioactive substances, buffalo milk can also provide health benefits to consumers. In Italy, buffalo milk is used mainly for cheese making, mozzarella PDO (Protected Designation of Origin), which is a highly valued dairy product. This 3‐year study, carried out between 2011 and 2013, was aimed at evaluating the quality of bulk Italian Mediterranean buffalo milk by monitoring physico‐chemical parameters, somatic cell and total bacterial counts. A total of 51 samples of bulk milk were collected from one herd throughout the monitored period. Analysis of variance, carried out to test month, season and year main effects, highlighted remarkable seasonal effects for fat, protein and lactose content, as well as for predicted mozzarella cheese yield, and somatic cell counts. The calculation of simple correlations allowed the identification of positive correlations between estimated cheese yield and fat and protein content.

Published: September 2017

ObjectivesThe aims of this study were to (1) report the incidence of laminitis among a population of horses and ponies attending Pony Clubs in Victoria, Australia, and (2) describe the dietary and management practices of the sample population.MethodsResearchers visited 10 Pony Clubs over a 10‐month period. Horse and pony owners completed a questionnaire to provide information on management relating to diet and exercise. Owners were also asked to report their animal’s history of laminitis, if any.ResultsFrom a survey population of 233 horses and ponies, 15.0% of animals (35 individuals) were reported to have suffered from at least one episode of laminitis. Of the animals that had suffered from laminitis, more than half had experienced multiple episodes. The majority of previously laminitic horses and ponies (71.4%) had not experienced an episode of laminitis within the past 12 months; however, 14.2% had experienced an incident within the past month. The proportion of ponies affected by laminitis (31/142; 21.8%) was significantly higher (P < 0.001) than the proportion of horses affected by laminitis (4/91; 4.4%). The incidence of laminitis within the pony group sampled was 6.5 cases per 100 pony years, while the incidence in horses was 0.55 cases per 100 horse years.ConclusionThis study provided information on the incidence of laminitis in the general population of pleasure horses and ponies in south‐eastern Australia. It also provided an overview of dietary and management practices. Given the high incidence of animals that had been affected by laminitis (and the associated welfare implications), this study highlights the importance of owner education regarding appropriate feeding and management strategies to reduce the risk of laminitis.

AbstractAimTo assess the outcomes of rectal excisional procedures in adults with chronic constipation.MethodStandardised methods and reporting of benefits and harms were used for all CapaCiTY reviews that closely adhered to PRISMA 2016 guidance. Main conclusions were presented as summary evidence statements with a summative Oxford Centre for Evidence‐Based Medicine (2009) level.ResultsForty‐seven studies were identified, providing data on outcomes in 8340 patients. Average length of procedures was 44 min and length of stay (LOS) was 3 days. There was inadequate evidence to determine variations in procedural duration or LOS by type of procedure. Overall morbidity rate was 16.9% (0–61%), with lower rates observed after Contour Transtar procedure (8.9%). No mortality was reported after any procedures in a total of 5896 patients. Although inconsistently reported, good or satisfactory outcome occurred in 73–80% of patients; a reduction of 53–91% in Longo scoring system for obstructive defecation syndrome (ODS) occurred in about 68–76% of patients. The most common long‐term adverse outcome is faecal urgency, typically occurring in up to 10% of patients. Recurrent prolapse occurred in 4.3% of patients. Patients with at least 3 ODS symptoms together with a rectocoele with or without an intussusception, who have failed conservative management, may benefit from a rectal excisional procedure.ConclusionRectal excisional procedures are safe with little major morbidity. It is not possible to advise which excisional technique is superior from the point of view of efficacy, peri‐operative variables, or harms. Future study is required.

Published: September 2017

ObjectiveThe clinical and echocardiographic parameters associated with the risk predictors of cryptogenic stroke (CS) in patients with patent foramen ovale (PFO) still diverse and with a great debate. We hypothesized that left atrial stiffness (LASt) and atrial dyssynchrony may increase the risk of CS in patients with PFO.MethodsA total of 129 consecutive patients presented without clinical reasoning of stroke were recruited. Transesophageal echocardiographic assessment was performed to investigate the presence of PFO. PFO was identified in 52% (group I) and absent in 48% (group II). Utilizing speckle‐tracking imaging LASt and atrial dyssynchrony was evaluated among patients with PFO (group I) vs those without PFO (group II).ResultsLASt was significantly increased in group I patients compared with group II (P < .001). Likewise patients with PFO had a significant LA dyssynchrony compared with those in group II (P < .001). Interatrial dyssynchrony and left atrial dyssynchrony were correlated with LASt (r = .47 and 0.51, respectively; P < .001). Cardiac arrhythmias were significantly encountered in group I patients (at presentation and with Holter monitoring) P < .001. Besides significantly increase in atrial dyssynchrony and in LASt in patients with arrhythmias compared with those without (P < .001). ROC analysis revealed that LASt index ≥ 0.61 and LA dyssynchrony ≥ 23.5 predicts cardiac arrhythmias in CS patients with PFO with (AUC: 0.85 and 0.87, respectively, P < .001).ConclusionIn conclusion, we demonstrated that LASt and atrial dyssynchrony might be risk markers of cryptogenic stroke in patients with PFO.
Reduced infancy and childhood epilepsy following hypothermia‐treated neonatal encephalopathy
Authors: Liu Xun , Jary Sally , Cowan Frances , Thoresen Marianne 
Published: September 2017

SummaryObjectiveTo investigate what proportion of a regional cohort of cooled infants with neonatal encephalopathy develop epilepsy (determined by the International League Against Epilepsy [ILAE] definition and the number of antiepileptic drugs [AEDs]) up to 8 years of age.MethodsFrom 2006–2013, 151 infants with perinatal asphyxia underwent 72 h cooling. Clinical and amplitude‐integrated electroencepalography (aEEG) with single‐channel EEG‐verified neonatal seizures were treated with AEDs. Brain magnetic resonance imaging (MRI) was assessed using a 0–11 severity score.Postneonatal seizures, epilepsy rates, and AED treatments were documented. One hundred thirty‐four survivors were assessed at 18–24 months; adverse outcome was defined as death or Bayley III composite Cognition/Language or Motor scores <85 and/or severe cerebral palsy or severely reduced vision/hearing. Epilepsy rates in 103 children age 4–8 years were also documented.ResultsaEEG confirmed seizures occurred precooling in 77 (57%) 151 of neonates; 48% had seizures during and/or after cooling and received AEDs. Only one infant was discharged on AEDs. At 18–24 months, one third of infants had an adverse outcome including 11% mortality. At 2 years, 8 (6%) infants had an epilepsy diagnosis (ILAE definition), of whom 3 (2%) received AEDs. Of the 103 4‐ to 8‐year‐olds, 14 (13%) had developed epilepsy, with 7 (7%) receiving AEDs. Infants/children on AEDs had higher MRI scores than those not on AEDs (median [interquartile range] 9 [8–11] vs. 2 [0–4]) and poorer outcomes. Nine (64%) of 14 children with epilepsy had cerebral palsy compared to 13 (11%) of 120 without epilepsy, and 10 (71%) of 14 children with epilepsy had adverse outcomes versus 23 (19%) of 120 survivors without epilepsy. The number of different AEDs given to control neonatal seizures, aEEG severity precooling, and MRI scores predicted childhood epilepsy.SignificanceWe report, in a regional cohort of infants cooled for perinatal asphyxia, 6% with epilepsy at 2 years (2% on AEDs) increasing to 13% (7% on AEDs) at early school age. These AED rates are much lower than those reported in the cooling trials, even with adjusting for our cohort′s milder asphyxia. Long‐term follow‐up is needed to document final epilepsy rates.

Published: September 2017

AbstractBackgroundAlthough different methods have been established to detect Helicobacter pylori (H. pylori) infection, identifying infected patients is an ongoing challenge. The aim of this meta‐analysis was to provide pooled diagnostic accuracy measures for stool PCR test in the diagnosis of H. pylori infection.MethodsIn this study, a systematic review and meta‐analysis were carried out on various sources, including MEDLINE, Web of Sciences, and the Cochrane Library from April 1, 1999, to May 1, 2016. This meta‐analysis adheres to the guidelines provided by the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses report (PRISMA Statement). The clinical value of DNA stool PCR test was based on the pooled false positive, false negative, true positive, and true negative of different genes.ResultsTwenty‐six of 328 studies identified met the eligibility criteria. Stool PCR test had a performance of 71% (95% CI: 68‐73) sensitivity, 96% (95% CI: 94‐97) specificity, and 65.6 (95% CI: 30.2‐142.5) diagnostic odds ratio (DOR) in diagnosis of H. pylori. The DOR of genes which showed the highest performance of stool PCR tests was as follows: 23S rRNA 152.5 (95% CI: 55.5‐418.9), 16S rRNA 67.9 (95%CI: 6.4‐714.3), and glmM 68.1 (95%CI: 20.1‐231.7).ConclusionsThe sensitivity and specificity of stool PCR test are relatively in the same spectrum of other diagnostic methods for the detection of H. pylori infection. In descending order of significance, the most diagnostic candidate genes using PCR detection were 23S rRNA, 16S rRNA, and glmM. PCR for 23S rRNA gene which has the highest performance could be applicable to detect H. pylori infection.
