Risk of cirrhosis-related complications in patients with advanced fibrosis following hepatitis C virus eradication
Background & Aims: The risk of hepatocellular carcinoma (HCC)
is reduced but not eradicated among patients with hepatitis C
virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of
cirrhosis-related complications in this specific group of patients.
Methods: Data from previously reported Western cohort studies
including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level. The primary endpoint was
HCC and the secondary endpoint was clinical disease progression,
defined as liver failure, HCC or death.
Results: Included were 1000 patients with SVR. Median age was
52.7 (IQR 45.1–59.7) years, 676 (68%) were male and 842 (85%)
had cirrhosis. Median follow-up was 5.7 (IQR 2.9–8.0) years.
Fifty-one patients developed HCC and 101 had clinical disease
progression. The cumulative 8-year HCC incidence was 1.8 (95%
CI 0.0–4.3) among patients with bridging fibrosis and 8.7% (95%
CI 6.0–11.4) among those with cirrhosis (p = 0.058). Within the
cirrhosis group, the 8-year HCC incidence was 2.6% (95% CI
0.0–5.5) among patients <45 years, 9.7% (95% CI 5.8–13.6) among
patients from 45–60 years, and 12.2% (95% CI 5.3–19.1) among
patients >60 years of age at start of therapy (p = 0.006).
Multivariable Cox analyses indicated that higher age, lower platelet
count and diabetes mellitus were independently associated with
development of HCC. After 8 years 4.2% (95% CI 0.1–8.3) of patients
with bridging fibrosis and 15.8% (95% CI 12.3–19.3) of patients with
cirrhosis experienced clinical disease progression (p = 0.007).
Conclusions: Patients with HCV-induced cirrhosis and SVR
showed an annual risk of approximately 1% for HCC and 2% for
clinical disease progression. Therefore, to prevent HCC surveillance, chronic HCV infection should preferably be treated before
cirrhosis has developed.
Lay summary: Patients with cirrhosis who were able to eradicate
their chronic HCV infection remain at substantial risk of primary
liver cancer. The risk of liver cancer increases with higher age,
laboratory makers suggesting more severe liver disease, and
presence of diabetes mellitus. Also after successful antiviral therapy patients with HCV-induced cirrhosis should thus remain
included in follow-up for early detection of liver cancer.

A finer grained approach to psychological capital and work performance
Purpose
Psychological capital is a set of personal resources comprised by hope, efficacy, optimism, and resilience, which previous research has supported as being valuable for general work performance. However, in today’s organizations, a multidimensional approach is required to understanding work performance, thus, we aimed to determine whether psychological capital improves proficiency, adaptivity, and proactivity, and also whether hope, efficiency, resilience, and optimism have a differential contribution to the same outcomes. Analyzing the temporal meaning of each psychological capital dimension, this paper theorizes the relative weights of psychological capital dimensions on proficiency, adaptivity, and proactivity, proposing also that higher relative weight dimensions are helpful to cope with job demands and perform well.
Methodology
Two survey studies, the first based on cross-sectional data and the second on two waves of data, were conducted with employees from diverse organizations, who provided measures of their psychological capital, work performance, and job demands. Data was modeled with regression analysis together with relative weights analysis.
Findings
Relative weights for dimensions of psychological capital were supported as having remarkable unique contributions for proficient, adaptive, and proactive behavior, particularly when job demands were high.
Originality/Value
We concluded that organizations facing high job demands should implement actions to enhance psychological capital dimensions; however, those actions should focus on the specific criterion of performance of interest
Developmental and evolutionary assumptions in a study about the impact of premature birth and low income on mother–infant interaction
In order to study the impact of premature
birth and low income on mother–infant interaction, four Portuguese samples were gathered: full-term, middle-class (n=99); premature, middle-class (n=63); full-term, low income (n=22); and premature, low income (n=21). Infants were filmed in a free play situation with their mothers, and the results were scored using the CARE Index. By means of multinomial regression analysis, social economic status (SES) was found to be the best predictor of maternal sensitivity and infant cooperative behavior within a set of medical and social factors. Contrary to the expectations of the cumulative risk perspective, two factors of risk (premature birth together with low SES) were as negative
for mother–infant interaction as low SES solely. In this study, as previous studies have shown, maternal sensitivity and infant cooperative behavior were highly correlated, as was maternal control with infant compliance. Our results further indicate that, when maternal lack of responsiveness
is high, the infant displays passive behavior, whereas when the maternal lack of responsiveness is medium, the infant
displays difficult behavior. Indeed, our findings suggest that, in these cases, the link between types of maternal and infant interactive behavior is more dependent on the degree of maternal lack of responsiveness than it is on birth status
or SES. The results will be discussed under a developmental and evolutionary reasonin
Mucosal Healing in Ulcerative Colitis: A Comprehensive Review
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice. The basic mechanisms behind colonic injury and MH are covered, highlighting the pathways through which different drugs exert their effect towards reducing inflammation and promoting epithelial repair. A comprehensive review of the evidence for approved drugs for UC to achieve and maintain MH is provided, including a section on the pharmacokinetics of anti-tumor necrosis factor (TNF)-alpha drugs. Currently approved drugs with proven efficacy in achieving MH in UC include salicylates, corticosteroids (induction only), calcineurin inhibitors (induction only), thiopurines, vedolizumab and anti-TNF alpha drugs (infliximab, adalimumab, and golimumab). MH is of crucial relevance in the outcomes of UC, resulting in lower incidences of clinical relapse, the need for hospitalization and surgery, as well as reduced rates of dysplasia and colorectal cancer. Finally, we present recent evidence towards the need for a more strict definition of complete MH as the preferred endpoint for UC patients, using a combination of both endoscopic and histological findings.info:eu-repo/semantics/publishedVersio
Obstetric and perinatal factors as predictors of child behaviour at 5 years
Objective To identify whether obstetric and perinatal factors are independent predictors of child behaviour at 5 years. Methodology The Mater University Study of Pregnancy (MUSP) is a prospective cohort study of 8556 mothers enrolled in early pregnancy. The relationship of obstetric and perinatal factors, maternal lifestyle, age and gender of the child, and social disadvantage were examined as predictors of child behaviour in 5005 children completing a modified child behaviour checklist at 5 years. This checklist contained three independent groups of behaviour: externalizng, internalizing and SAT (social, attentional and thought problems). Results In the initial analysis a limited number of associations were present. After adjusting for measures of social disadvantage, only number of antenatal admissions was associated with child behaviour in all three scales, while maternal cigarette smoking in pregnancy and male gender were associated with externalising and SAT behaviours. Conclusions Most common epidemiologic obstetric and perinatal risk factors were not independent predictors of behaviour problems in children at 5 years

Comparisons of the factor structure and measurement invariance of the Spence children’s anxiety scale - parent version in children with autism spectrum disorder and typically developing anxious children
The Spence Children’s Anxiety Scale - Parent version (SCAS-P) is often used to assess anxiety in children with autism spectrum disorder (ASD), however, little is known about the validity of the tool in this population. The aim of this study was to determine whether the SCAS-P has the same factorial validity in a sample of young people with ASD (n=285), compared to a sample of typically developing young people with anxiety disorders (n=224). Poor model fit with all of the six hypothesised models precluded invariance testing. Exploratory factor analysis indicated that different anxiety phenomenology characterises the two samples. The findings suggest that cross-group comparisons between ASD and anxious samples based on the SCAS-P scores may not always be appropriat
Measuring commissioners’ willingness-to-pay for community based childhood obesity prevention programmes using a discrete choice experiment
Background:
In the UK, rates of childhood obesity remain high. Community based programmes for child obesity prevention are available to be commissioned by local authorities. However, there is a lack of evidence regarding how programmes are commissioned and which attributes of programmes are valued most by commissioners. The aim of this study was to determine the factors that decision-makers prioritise when commissioning programmes that target childhood obesity prevention.
Methods:
An online discrete choice experiment (DCE) was used to survey commissioners and decision makers in the UK to assess their willingness-to-pay for childhood obesity programmes.
Results:
A total of 64 commissioners and other decision makers completed the DCE. The impact of programmes on behavioural outcomes was prioritised, with participants willing to pay an extra £16,600/year if average daily fruit and vegetable intake increased for each child by one additional portion. Participants also prioritised programmes that had greater number of parents fully completing them, and were willing to pay an extra £4810/year for every additional parent completing a programme. The number of parents enrolling in a programme (holding the number completing fixed) and hours of staff time required did not significantly influence choices.
Conclusions:
Emphasis on high programme completion rates and success increasing children’s fruit and vegetable intake has potential to increase commissioning of community based obesity prevention programmes
Nothing Lasts Forever: Environmental Discourses on the Collapse of Past Societies
The study of the collapse of past societies raises many questions for the theory and practice of archaeology. Interest in collapse extends as well into the natural sciences and environmental and sustainability policy. Despite a range of approaches to collapse, the predominant paradigm is environmental collapse, which I argue obscures recognition of the dynamic role of social processes that lie at the heart of human communities. These environmental discourses, together with confusion over terminology and the concepts of collapse, have created widespread aporia about collapse and resulted in the creation of mixed messages about complex historical and social processes
Girls' disruptive behavior and its relationship to family functioning: A review
Although a number of reviews of gender differences in disruptive behavior and parental socialization exist, we extend this literature by addressing the question of differential development among girls and by placing both disruptive behavior and parenting behavior in a developmental framework. Clarifying the heterogeneity of development in girls is important for developing and optimizing gender-specific prevention and treatment programs. In the current review, we describe the unique aspects of the development of disruptive behavior in girls and explore how the gender-specific development of disruptive behavior can be explained by family linked risk and protective processes. Based on this review, we formulate a gender-specific reciprocal model of the influence of social factors on the development of disruptive behavior in girls in order to steer further research and better inform prevention and treatment programs
