Evolving Notions of Schizophrenia as a Developmental Neurocognitive Disorder
Authors: Seidman Larry J. , Mirsky Allan F. 
Published: December 2017

AbstractWe review the changing conceptions of schizophrenia over the past 50 years as it became understood as a disorder of brain function and structure in which neurocognitive dysfunction was identified at different illness phases. The centrality of neurocognition has been recognized, especially because neurocognitive deficits are strongly related to social and role functioning in the illness, and as a result neurocognitive measures are used routinely in clinical assessment of individuals with schizophrenia. From the original definitions of the syndrome of schizophrenia in the early 20th century, impaired cognition, especially attention, was considered to be important. Neurocognitive impairments are found in the vast majority of individuals with schizophrenia, and they vary from mild, relatively restricted deficits, to dementia-like syndromes, as early as the first psychotic episode. Neurocognitive deficits are found in the premorbid phase in a substantial minority of pre-teenage youth who later develop schizophrenia, and they apparently worsen by the prodromal, high-risk phase in a majority of those who develop the illness. While there is limited evidence for reversibility of impairments from pharmacological interventions in schizophrenia, promising results have emerged from cognitive remediation studies. Thus, we expect cognitive interventions to play a larger role in schizophrenia in the coming years. Moreover, because youth at risk for schizophrenia can be identified by an emergent high-risk syndrome, earlier interventions might be applied in a pre-emptive way to reduce disability and improve adaptation. The notion of schizophrenia as a developmental neurocognitive disorder with stages opens up a window of possibilities for earlier interventions. (JINS, 2017,23, 881–892)

AbstractObjectiveMobile phones can replace traditional self-monitoring tools through cell phone-based ecological momentary assessment (CEMA) of lifestyle behaviours and camera phone-based images of meals, i.e. photographic food records (PFR). Adherence to mobile self-monitoring needs to be evaluated in real-world treatment settings. Towards this goal, we examine CEMA and PFR adherence to the use of a mobile app designed to help mothers self-monitor lifestyle behaviours and stress.Design/SettingIn 2012, forty-two mothers recorded CEMA of diet quality, exercise, sleep, stress and mood four times daily and PFR during meals over 6 months in Los Angeles, California, USA.SubjectsA purposive sample of mothers from mixed ethnicities.ResultsAdherence to recording CEMA at least once daily was higher compared with recording PFR at least once daily over the study period (74v. 11 %); adherence to both types of reports decreased over time. Participants who recorded PFR for more than a day (n31) were more likely to be obesev. normal- to overweight and to have higher blood pressure, on average (allP<0·05). Based on random-effects regression, CEMA and PFR adherence was highest during weekdays (bothP<0·01). Additionally, PFR adherence was associated with older age (P=0·04). CEMA adherence was highest in the morning (P<0·01). PFR recordings occurred throughout the day.ConclusionsVariations in population and temporal characteristics should be considered for mobile assessment schedules. Neither CEMA nor PFR alone is ideal over extended periods.
Meeting UK dietary recommendations is associated with higher estimated consumer food costs: an analysis using the National Diet and Nutrition Survey and consumer expenditure data, 2008–2012

AbstractObjectiveTo test whether diets achieving recommendations from the UK’s Scientific Advisory Committee on Nutrition (SACN) were associated with higher monetary costs in a nationally representative sample of UK adults.DesignA cross-sectional study linking 4 d diet diaries in the National Diet and Nutrition Survey (NDNS) to contemporaneous food price data from a market research firm. The monetary cost of diets was assessed in relation to whether or not they met eight food- and nutrient-based recommendations from SACN. Regression models adjusted for potential confounding factors. The primary outcome measure was individual dietary cost per day and per 2000 kcal (8368 kJ).SettingUK.SubjectsAdults (n 2045) sampled between 2008 and 2012 in the NDNS.ResultsOn an isoenergetic basis, diets that met the recommendations for fruit and vegetables, oily fish, non-milk extrinsic sugars, fat, saturated fat and salt were estimated to be between 3 and 17 % more expensive. Diets meeting the recommendation for red and processed meats were 4 % less expensive, while meeting the recommendation for fibre was cost-neutral. Meeting multiple targets was also associated with higher costs; on average, diets meeting six or more SACN recommendations were estimated to be 29 % more costly than isoenergetic diets that met no recommendations.ConclusionsFood costs may be a population-level barrier limiting the adoption of dietary recommendations in the UK. Future research should focus on identifying systems- and individual-level strategies to enable consumers achieve dietary recommendations without increasing food costs. Such strategies may improve the uptake of healthy eating in the population.

Published: December 2017

AbstractObjectiveYoung children lack basic skills related to recognizing the types of foods they consume and dietary surveys often rely on parents’ response. The present study aimed to evaluate how well parents of children aged from 3 months to 10 years perceive images of portions of foods commonly consumed by young children.DesignPre-weighed, actual food portions (n 2314) were shown to the study participants who were asked to indicate the picture that corresponded to the food in view. Mean differences between picture numbers selected and shown were estimated and compared using unpaired t tests or Tukey–Cramer pairwise comparisons.SettingReal-time testing of parents’ perception of food images presenting portion sizes consumed by children up to 10 years old.SubjectsA convenience sample of 138 parents/caregivers of young children (69 % females).ResultsIndividuals selected the correct or adjacent image in about 97 % of the assessments. Images presenting amorphous solids (i.e. pies and pastries with a filling), liquid or semi-liquid dishes (i.e. soups, porridges, fruit and vegetable purées) were more prone to bias. There was no indication that personal characteristics (gender, age, educational background, age, number of offspring) were associated with differences in the way parents/caregivers perceived the food pictures.ConclusionsFood pictures may not be appropriate to quantify the intake of liquid, semi-liquid or amorphous solid foods in surveys addressing young children and studies evaluating their performance as food portion anchors should ensure the inclusion of several and various amorphous foods in the assessment.
Selectively Electron-Transparent Microstamping Toward Concurrent Digital Image Correlation and High-Angular Resolution Electron Backscatter Diffraction (EBSD) Analysis

Published: December 2017

AbstractDigital image correlation (DIC) in a scanning electron microscope and high-angular resolution electron backscatter diffraction (HREBSD) provide valuable and complementary data concerning local deformation at the microscale. However, standard surface preparation techniques are mutually exclusive, which makes combining these techniquesin situimpossible. This paper introduces a new method of applying surface patterning for DIC, namely a urethane microstamp, that provides a pattern with enough contrast for DIC at low accelerating voltages, but is virtually transparent at the higher voltages necessary for HREBSD and conventional EBSD analysis. Furthermore, microstamping is inexpensive and repeatable, and is more suitable to the analysis of patterns from complex surface geometries and larger surface areas than other patterning techniques.
Nucleation and Growth of Mg-Calcite Spherulites Induced by the BacteriumCurvibacter lanceolatusStrain HJ-1

Published: December 2017

AbstractCalcite spherulites have been observed in many laboratory experiments with different bacteria, and spherulitic growth has received much interest in mineralogy research. However, the nucleation and growth mechanism, as well as geological significance of calcite spherulites in solution with bacteria is still unclear. Herein, spherulites composed of an amorphous core, a Mg-calcite body and an organic film were precipitated by theCurvibacter lanceolatusHJ-1 bacterial strain in a solution with a molar Mg/Ca ratio of 3. Based on the results, we provide a possible mechanism for the biomineralization of Mg-calcite spherulites. First, amorphous calcium carbonate particles are deposited and aggregated into a stable sphere-like core in combination with organic molecules. The core then acts as the nucleus of spherulitic radial growth. Finally, the organic film grows on the surface of Mg-calcite spherulites as a result of bacterial metabolism and calcification. These findings provide insight into the growth mode and crystallization of biogenic spherulites during biomineralization, and are of significance in the application of novel biological materials.

Published: December 2017

AbstractPurposeWhole-breast external beam radiotherapy results in significant reduction in the risk for breast cancer-related death, but this may be offset by an increase in deaths from other causes and toxicity to surrounding organs. Partial breast irradiation techniques are approaches that treat only the lumpectomy area rather than the whole breast. Quality assurance in the radiation therapy treatment planning process is essential to ensure accurate dose delivery to the patient. For this purpose, this article compares the results from an anthropomorphic PRESAGE® dosimeter, radiation treatment planning system and from the GAFCHROMIC® EBT2 film.Materials and methodsA breast dosimeter was created and a three-field partial plan was generated in the Pinnacle3 treatment planning system. Dose distribution comparisons were made between Pinnacle3 treatment planning system, GAFCHROMIC® EBT2 film and PRESAGE® dosimeter. Dose–volume histograms (DVHs), gamma maps and line profiles were used to evaluate the comparison.ResultsDVHs of gross tumour volume, clinical tumour volume and planning tumour volume for the PRESAGE® dosimeter and Pinnacle3 treatment planning system shows that both measured and calculated statistics were in agreement, with a value of 97.8% of the prescribed dose. Gamma map comparisons showed that all three distributions passed 95% at the ±3%/±3 mm criteria. Comparisons of isodose line distribution between the PRESAGE® dosimeter, EBT2 film and planning system demonstrated agreement, with an average difference of 1.5%.ConclusionsThis work demonstrated the feasibility of PRESAGE® to function as an anthropomorphic phantom and laid the foundation for research studies in PRESAGE®/optical-computed tomography three-dimensional dosimetry with the most complex anthropomorphic phantoms.
Developing a community HCV service: project ITTREAT (integrated community-based test – stage – TREAT) service for people who inject drugs

Published: December 2017

Background and aimsMajority of the individuals with hepatitis C virus (HCV) infection in England are people who inject drugs, a vulnerable and disenfranchised cohort with poor engagement with secondary care. Our aim is to describe our experiences in setting up a successful nurse led HCV service at a substance misuse service (SMS).MethodsWe justify the need for a community HCV service and review the different community based models. Our experiences in engaging with stakeholders, obtaining funding, service set up, challenges faced and key recommendations are discussed. Finally, a summary of interim clinical outcomes is presented.ResultsA successful community based “one-stop” nurse led HCV service was set up in Dec 2013 at a large SMS. It provides all aspects of care (blood borne virus screening, non-invasive assessment of hepatic fibrosis, Hepatology input, HCV treatment, peer mentor, social and psychiatrist support, and opiod substitution) at one site. Interim clinical data indicate high service uptake with HCV treatment outcomes comparable to secondary care.ConclusionsThe advent of direct acting antivirals provides a unique opportunity for HCV elimination in England by 2030. Our “one-stop” integrated and multidisciplinary community HCV model suggests that HCV care can be successfully delivered outside of a hospital setting and warrants national adoption.
Reformers' unfulfilled promises: accountability deficits in Argentinean criminal courts
Authors: Ciocchini Pablo 
Published: December 2017

AbstractSince the late 1980s, following the transition to democratic rule in Latin America, criminal courts all over the continent have been going through a process of continuous reform. Reformers introduced an adversarial-based procedural system, arguing that it would guarantee due process and greater transparency and accountability. However, in recent years, the emphasis of this reformist narrative has changed from expanding defendants' rights towards improving the efficacy of the system. This paper explores how the original principles of transparency and accountability have been upheld in criminal courts in one of the first areas of jurisdiction to implement those changes: the Province of Buenos Aires. Based on an analysis of data from forty-five in-depth interviews with key informants and court observations, this paper explores how the reforms developed a managerial rationality in criminal courts that may undermine the due process in Latin American jurisdictions that have undergone similar democratic reform processes.

Published: December 2017

Aims.The aim of this study was to identify the risk correlates for coexisting common mental disorders (CMDs) in the chronic care population in South Africa, with the view to identifying particularly vulnerable patient populations.Methods.The sample comprised 2549 chronic care patients enrolled in the baseline and endline rounds of a facility detection survey conducted by the Programme for Improving Mental Health Care in three large facilities in the Dr Kenneth Kaunda district in the North West province of South Africa. Participants were screened for depression using the Patient Health Questionnaire (PHQ9) and for alcohol misuse using the Alcohol Use Disorders Identification Test (AUDIT). Data were analysed according to the number of morbidities, disorder type (physical or mental) and demographic variables. Multimorbidity was defined as the presence of two or more disorders (physical and/or mental).Results.Just over one-third of the sample reported two or more physical conditions. Women were more at risk of being depressed than were men, with men more at risk of alcohol misuse. Those who were employed were at lower risk of having coexisting CMDs, while being younger, HIV positive, and food deprived were all found to be associated with higher risk for having coexisting CMDs.Conclusion.In the face of the large treatment gap for CMDs in South Africa, and the role that coexisting CMDs can play in exacerbating the burden of chronic physical diseases, mental health screening and treatment interventions should target HIV-positive, younger patients living in circumstances where there is household food insecurity.

Published: December 2017

AbstractInconsistent condom use in young people is related to the perceived barriers to their use. The psychometric properties and factor structure of the new Condom Use Barriers Scale for Adolescents (CUBS-A) are analyzed. Concurrent validity was assessed by the Attitude towards condom use subscale of the validated HIV-AS test and the percentage of condom use variable. A total of 629 Spanish adolescents whose mean age was 15.17 (SD = 1.09; 51.5% boys) participated. Exploratory factor analysis supported a 15–item instrument with four factors: negotiation skills, perceived feelings, negative aspects of condoms, and disruption of the sexual experience, which explained 41.89% of the total variance (KMO = .84; χ2 = 1071.93; p < .001). The results show high internal consistency (α = .86) and a good fit of the data to the model (NNFI = .93; CFI = .95; IFI = .95; RMSEA = .04). Its total score and most of its factors show acceptable correlation with the percentage of condom use, values that support the criterial validity (p ≤ .05). Gender differences were found in most subscales (p ≤ .001). The CUBS-A is a valid and reliable new instrument for assessing perceived barriers in adolescents for using condoms to protect themselves during sexual intercourse.

Published: December 2017

AbstractThe Padua Inventory (PI) of obsessions and compulsions is one of the most usually applied tests to assess obsessive-compulsive symptomatology in research contexts as well as for clinical and screening purposes. A reliability generalization meta-analysis was accomplished to estimate the average reliability of the PI scores and to search for characteristics of the samples and studies that can explain the variability among reliability estimates. An exhaustive literature search enabled us to select 39 studies (53 independent samples) that reported alpha and/or test-retest coefficients with the data at hand for the PI total score and subscales. An excellent average coefficient alpha was found for the PI total score (M= .935; 95%CI = .922–.949) and for Impaired Mental Control subscale (M= .911; 95%CI = .897–.924), being good for Contamination (M= .861; 95%CI = .841–.882) and Checking (M= .880; 95%CI = .856–.903), and fair for Urges and Worries (M= .783; 95%CI = .745–.822). The average test-retest reliability for PI total score was also satisfactory (M= .835; 95%CI = .782–.877). Moderator analyses showed larger coefficients alpha for larger standard deviation of the PI total scores (p= .0005;R2= .46), for adapted versions of the test (p= .002;R2= .32), and for samples composed of clinical participants (p= .066;R2= .10). The practical implications of these results are discussed as well as the need for researchers to report reliability estimates with the data at hand.

AbstractThis study uses ecological momentary assessment (EMA) with smartphone devices to examine community adolescents’ perceptions regarding both the intensity of and variability in their daily sadness/depression, anxiety, and somatic problems over the period of one week. Participants were 90 high-school students (Mage = 14.61, SD = 1.64; range 12–18). The sample was divided according to gender (61.1% girls), migratory status (68.5% Spanish nationals and 31.5% Latin American immigrants), and level of psychological symptoms (17% risk group). Sadness/depression, anxiety, and somatic problems were examined using a smartphone app, five times per day, semi-randomly, for seven days (35 possible moments). A high proportion of adolescents did not report feelings of sadness (80.0%) or worry (79.3%) or physical symptoms on a daily basis (84.9%). Girls and the risk group reported greater intensity levels for the three analyzed problems than did boys and the normal group, respectively (p < .001 in all cases). Migratory status was not associated with any significant differences in the analyzed problems over the one-week period (p > .05 in all cases). Day-to-day fluctuations in mood during the week were statistically significant but not meaningful (b = 0.0004, 95% CI [0.0001, 0.0008], p = .001).
Aggressors and Victims in Bullying and Cyberbullying: A Study of Personality Profiles using the Five-Factor Model
Authors: Alonso Cristina , Romero Estrella 
Published: December 2017

AbstractBullying and cyberbullying are highly prevalent in today’s society. However, the personality profiles of different roles involved in this phenomenon remain little known. This study aims (1) to examine the association between bullying and cyberbullying in adolescents; and (2) to analyze the relationship between bullying and cyberbullying in terms of the domains and facets of the five-factor model (FFM). A total of 910 adolescents aged 12 to 19 years old participated. They were administered self-report assessments of aggression and victimization in bullying and cyberbullying, as well as the JS-NEO-S questionnaire. The results provide evidence of co-occurrence between bullying and cyberbullying (p < .001). We observed higher neuroticism in victims and aggressor-victims, higher openness in victims, higher agreeableness in victims and non-aggressor non-victims and higher conscientiousness in non-aggressor non-victims as compared with the rest of the groups (p < .001). Comparison of the four cyberbullying groups showed that cybervictims score higher in neuroticism and openness, cybervictims and non-cybervictims non-cyberaggressors score higher in agreeableness and non-cybervictims non-cyberaggressors score higher in conscientiousness (p < .001) In conclusion, this study provides a broad, systematic view of the personality traits associated with different roles implicated in traditional bullying and cyberbullying.
