Abstract
Pancreatic cancer has the highest mortality amongst all major organ cancers. Early detection is key to reduce deaths related to pancreatic cancer. However, early detection has been challenged by the lack of non-invasive biomarkers with enough sensitivity and specificity to allow for screening. The gold standard is still carbohydrate antigen (CA 19-9), against which all new biomarkers must be evaluated. In this paper, we describe recent progress in the development of new pancreatic cancer biomarkers, focusing on proteins, metabolites, and genetic and epigenetic biomarkers. Although several promising biomarkers have been identified, they are all derived from retrospective studies and additional prospective studies are needed to confirm their clinical validity.

Abstract
Hepatitis C virus-infected (HCV+) adults evidence increased rates of psychiatric and cognitive difficulties. This is the first study to use functional magnetic resonance imaging (fMRI) to examine brain activation in untreated HCV+ adults. To determine whether, relative to non-infected controls (CTLs), HCV+ adults exhibit differences in brain activation during a delay discounting task (DDT), a measure of one's tendency to choose smaller immediate rewards over larger delayed rewards-one aspect of impulsivity. Twenty adults with HCV and 26 CTLs completed an fMRI protocol during the DDT. Mixed effects regression analyses of hard versus easy trials of the DDT showed that, compared with CTLs, the HCV+ group exhibited less activation in the left lateral occipital gyrus, precuneus, and superior frontal gyrus. There were also significant interactive effects for hard-easy contrasts in the bilateral medial frontal gyrus, left insula, left precuneus, left inferior parietal lobule, and right temporal occipital gyrus; the CTL group evidenced a positive relationship between impulsivity and activation, while the HCV+ group exhibited a negative relationship. Within the HCV+ group, those with high viral load chose immediate rewards more often than those with low viral load, regardless of choice difficulty; those with low viral load chose immediate rewards more often on hard choices relative to easy choices. Results show that HCV+ patients exhibit greater impulsive behavior when presented with difficult choices, and impulsivity is negatively related to activation in regions important for cognitive control. Thus, interventions that decrease impulsive choice may be warranted with some HCV+ patients.

Abstract
Drowning is the 3rd leading cause of unintentional injury death worldwide, with the highest rates of fatality among young children. Submersion injuries with cardiac arrest can lead to long-term neurologic morbidity. Severe hypothermic submersion injuries have complex treatment courses and survivors have variable neurocognitive outcomes. We describe the course of a hypothermic submersion injury in a 6-year-old previously healthy boy. The description includes premorbid and post-injury neurocognitive functioning. A review of the literature of pediatric cold-water submersion injury was performed. Despite prolonged cardiopulmonary resuscitation (>100 min) and water temperature well above freezing, our patient had an optimal neurocognitive outcome following hypothermic submersion injury. Available literature is limited but suggests that increased submersion time, increased duration of resuscitation, and higher water temperatures are associated with worse outcomes. Care guidelines have been created, but outcomes related to these guidelines have not been studied. Our case highlights potential important determinants of outcome after drowning. Incident specific characteristics and therapeutic interventions should be considered when evaluating this population. Treatment guidelines based on currently available literature may fail to incorporate all potential variables, and consideration should be given to prolonged resuscitative efforts based on individual case characteristics until further data is available.

Abstract
Aim of the Study The outcome quality of medical rehabilitation is evaluated often by "Patient Reported Outcomes" (PROs). It is examined to what extent these PROs are corresponding with "hard" or "objective" outcomes such as payments of contributions to social insurance. Methods The "rehabilitation QM outcome study" includes self-reports of patients as well as data from the Rehabilitation Statistics Database (RSD) of the German pension insurance Baden-Wurttemberg. The sample for the question posed includes N=2 947 insured who were treated in 2011 in 21 clinics of the "health quality network" and who were either employed or unemployed at the time of the rehabilitation application (e. g. the workforce or labour force group, response rate: 55%). The sample turned out widely representative for the population of the insured persons. Results PROs and payment of contributions to pension insurance clearly correspond. In the year after the rehabilitation improved vs. not improved rehabilitees differed clearly with regard to their payments of contributions. Conclusions The results support the validity of PROs. For a comprehensive depiction of the outcome quality of rehabilitation PROs and payments of contributions should be considered supplementary.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that impacts communicative interactions, with patterns of repetitive and restricted behaviors, interests, and cognitive rigidity. Recent incidence rate estimates for ASD are 1 in 68, and primarily male (4:1). A major epidemiological issue in ASD is transitioning to independence in adulthood, particularly navigating the healthcare system. This commentary will focus on approaches healthcare providers can use to not overlook and support individuals with ASD.

Abstract
Attention-deficit/hyperactive disorder (ADHD) and autism spectrum disorders (ASD) are two of the most common and vexing neurodevelopmental disorders among children. Although the two disorders share many behavioral and neuropsychological characteristics, most MRI studies examine only one of the disorders at a time. Using graph theory combined with structural and functional connectivity, we examined the large-scale network organization among three groups of children: a group with ADHD (8-12 years, n = 20), a group with ASD (7-13 years, n = 16), and typically developing controls (TD) (8-12 years, n = 20). We apply the concept of the rich-club organization, whereby central, highly connected hub regions are also highly connected to themselves. We examine the brain into two different network domains: (1) inside a rich-club network phenomena and (2) outside a rich-club network phenomena. The ASD and ADHD groups had markedly different patterns of rich club and non rich-club connections in both functional and structural data. The ASD group exhibited higher connectivity in structural and functional networks but only inside the rich-club networks. These findings were replicated using the autism brain imaging data exchange dataset with ASD (n = 85) and TD (n = 101). The ADHD group exhibited a lower generalized fractional anisotropy and functional connectivity inside the rich-club networks, but a higher number of axonal fibers and correlation coefficient values outside the rich club. Despite some shared biological features and frequent comorbity, these data suggest ADHD and ASD exhibit distinct large-scale connectivity patterns in middle childhood.

Abstract
BackgroundThe purpose of this study was to characterize hepatitis C virus (HCV)-associated differences in the expression of 47 inflammatory factors and to evaluate the potential role of peripheral immune activation in HCV-associated neuropsychiatric symptoms-depression, anxiety, fatigue, and pain. An additional objective was to evaluate the role of immune factor dysregulation in the expression of specific neuropsychiatric symptoms to identify biomarkers that may be relevant to the treatment of these neuropsychiatric symptoms in adults with or without HCV. MethodsBlood samples and neuropsychiatric symptom severity scales were collected from HCV-infected adults (HCV+, n = 39) and demographically similar noninfected controls (HCV-, n = 40). Multi-analyte profile analysis was used to evaluate plasma biomarkers. ResultsCompared with HCV- controls, HCV+ adults reported significantly (P < 0.050) greater depression, anxiety, fatigue, and pain, and they were more likely to present with an increased inflammatory profile as indicated by significantly higher plasma levels of 40% (19/47) of the factors assessed (21%, after correcting for multiple comparisons). Within the HCV+ group, but not within the HCV- group, an increased inflammatory profile (indicated by the number of immune factors > the LDC) significantly correlated with depression, anxiety, and pain. Within the total sample, neuropsychiatric symptom severity was significantly predicted by protein signatures consisting of 4-10 plasma immune factors; protein signatures significantly accounted for 19-40% of the variance in depression, anxiety, fatigue, and pain. ConclusionsOverall, the results demonstrate that altered expression of a network of plasma immune factors contributes to neuropsychiatric symptom severity. These findings offer new biomarkers to potentially facilitate pharmacotherapeutic development and to increase our understanding of the molecular pathways associated with neuropsychiatric symptoms in adults with or without HCV.

Abstract
Higher levels of cognitive reserve (CR) can be protective against the neuropsychological manifestation of neural injury across a variety of clinical disorders. However, the role of CR in the expression of neurocognitive deficits among persons infected with the hepatitis C virus (HCV) is not well understood. Thirty-nine HCV-infected participants were classified as having either high (n = 19) or low (n = 20) CR based on educational attainment, oral word reading, and IQ scores. A sample of 40 demographically comparable healthy adults (HA) was also included. All participants completed the Neuropsychological Assessment Battery, Delis-Kaplan Executive Function System, and Behavioral Rating Inventory of Executive Function, Adult Version (BRIEF-A). Linear regression analyses, controlling for gender, depression, and lifetime substance use disorders, found significant effects of HCV/CR group on verbal fluency, executive functions, and daily functioning T scores, but not in learning or the BRIEF-A. Pairwise comparisons revealed that the HCV group with low CR performed significantly below the HCV high CR and HA cohorts, who did not differ from one another. Findings indicate that higher levels of CR may be a protective factor in the neurocognitive and real-world manifestation of neural injury commonly associated with HCV infection.

Abstract
The German care quality assurance law ("Pflege-Qualitätssicherungs-Gesetz", PQsG) calls for internal quality management in residential care facilities. Empirical surveys with residents, their relatives and employees are essential to get transparency and to assess the quality of service. Within the scope of the present study more than 1400 relatives of residents of 31 residential care institutions were surveyed. Therefore in preliminary studies a questionnaire for the relatives was developed, which collects data concerning quality aspects on various aspects (for example care, staff, medical care, cooperation with relatives). On the average, relatives judged the quality of the institutions as good. The overall mean of 2.2 (scale values between 1.8 ["administration/management"] and 2.5 ["care"]) reveals a positive aspect, but there is substantial variation between institutions. Empirical surveys are important tools for internal quality management. Among other things, their results can be used as input for specific quality circle work and thus for continuous improvement. Used continually in the sense of a routine-monitoring system, surveys can also serve to evaluate quality management procedures.

Abstract
Detection of the common electrochemical interferents, ascorbic acid and hydrogen peroxide, using a SIRE (Sensors based on Injection of the Recognition Element) technology based biosensor in reverse mode operation is reported. The differential measuring principle employed in the SIRE biosensor during operation in reverse mode is such that the sample is measured first in the presence of enzyme (yielding matrix signal only), and then measured again in the absence of enzyme (yielding signal from matrix+analyte). Subtraction of the signal obtained in the presence of enzyme from the signal obtained in the absence of enzyme gives a specific signal for the analyte only and correlates directly to its concentration in solution. The linear range for the determination of ascorbic acid and hydrogen peroxide was 0-3 mM and 0-2 mM, respectively, with an enzyme concentration of 25 U ascorbate oxidase/ml and 1000 U catalase/ml. The reproducibility was 5% for ascorbic acid (R.S.D. n=15) and 10% for hydrogen peroxide (R.S.D. n=18). The cost per measurement was 0.28 USD for ascorbic acid analysis and 0.0008 USD for hydrogen peroxide analysis. The degradation of ascorbic acid in cereal was followed in real-time, as was the stabilization of low pH on the degradation process.

Abstract
Recently, a magneto binding assay was conducted. The operational principle is based on a 'sandwich' mode of detection, where the target analyte (Concanavalin A) becomes bound nonselectively by protein adsorption between the solid support (silica carrier particles) and the ferromagnetic label (magneto markers). A magnetic transducer was employed for the detection. The binding assay gave a linear response in the dynamic range of 0-1.9 microM and proved to be sensitive by having a limit of detection at 250 nM. Furthermore, the relative standard deviation observed was 6.2% (n = 3). The demonstration of the 'sandwich' approach is a step toward achieving magneto immunoassays (MIA).

Abstract
The field of molecular imprinting has undergone rapid expansion in recent years, and applications have been demonstrated for imprinted materials in separations, analysis and catalysis. The range of compounds that has been imprinted has also expanded. Imprinted polymers have been used for the chromatographic separation of amino acids, sugars, drugs and nucleotides. Drugs have been measured using imprinted polymers as antibody substitutes in radioligand binding assays. Applications are being found for imprinted polymers in biomimetic sensing devices and sensors. Particularly interesting developments from the past year include ligand binding assays for morphine in aqueous buffers with similar specificity to antibody-based assays and the imprinting of cholesterol using a novel procedure in which the template is covalently bonded to the monomer during polymerization, but after cleavage, rebinds the polymer only by non-covalent interactions.

Abstract
The purpose of this double-blind, placebo-controlled, comparative study was to evaluate the specific clinical efficacy and tolerance of human leukocyte interferon-alpha (2 x 10(6) IU/g) and podophyllotoxin 0.5% incorporated in a hydrophilic cream to cure genital warts. Preselected Asian women (n = 60) aged 18-40 years (mean 22.9), with a clinical and biopsy-confirmed diagnosis of genital warts, harboring 322 lesions (mean 5.36) were randomly assigned to three parallel groups to receive one of the two test drugs or placebo. Each patient received a precoded tube (40 g) containing either human leukocyte interferon-alpha, podophyllotoxin, or identically appearing placebo cream for 3 days' usage. In addition to written instructions, each subject was shown how to apply a minimal amount of trial medication on their lesions thrice daily for 3 consecutive days per week (maximum nine topical applications per week). Patients were examined on a weekly basis, and a cure was considered to be a biopsy-confirmed, total elimination of a lesion. Moreover, patients cured during the study period were spared further therapy, and were requested to return in 16 weeks to monitor for the occurrence of a relapse. The remaining patients' empty tubes were collected, and similarly precoded replacement tubes were given to continue the treatment; a total of 214 tubes were used. The study was scheduled for 16 weeks with 4 weeks of active treatment. Individuals were excluded from the study due to pregnancy, breast feeding, or the receiving of any type of antiviral therapy during the 4 weeks preceding enrollment.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In this paper, the data on some medical, social and legal aspects of abuse and/or neglect of children in Zagreb are presented which, at least, partially illustrate this societies' care of mistreated children at the end of the 20th century. We reviewed questionnaires that were administered to 44 health institutions involved in the childrens' health control and/or treatment and to 14 social work services and analyzed cases of child mistreatment reported to the Zagreb Public Prosecution Office and final court judgements for 1987 to 1988. We conclude that all these institutions encounter cases of child abuse and/or neglect but that medical institutions identify only 10% of cases detected by social work services and that judicial system sentences with imprisonment about 30% of abusers. Underdetection of child mistreatment in Zagreb, in addition to poor coordination of services, are the possible reasons for insufficient concern for these children. Up to now, only mass media and scientific publications have spoken more loudly about this problem. The authors emphasize the need and obligation of all those professionals concerned with children and of the entire community to undertake relevant measures to protect abused and/or neglected children.
