Predicting saturated fat consumption: Exploring the role of subjective well-being

Consumption of saturated fat (SF) is associated with obesity, cardiovascular disease and cancer; which are among the leading causes of death in Australia and worldwide. A causal relationship between subjective well-being and positive health outcomes has been established, although few studies have specifically focused on health-enhancing or health-risk behaviours. The aim of this research was to develop an improved understanding of the processes underlying SF consumption by exploring the relationship between subjective well-being and SF consumption, within the Theory of Planned Behaviour framework. Questionnaires related to the TPB variables, subjective well-being and SF intake were administered online to 96 participants. Perceived behavioural control (PBC) was found to be a significant predictor of intention to limit SF intake. Intention and PBC accounted for 25% of variance in behaviour; with PBC the only significant predictor of SF consumption. While subjective well-being variables were not significant unique predictors of SF consumption, these variables contributed an additional 2% to the prediction of behaviour, and this model was significant. The addition of subjective well-being to the TPB is novel and the results partially support the potential of subjective well-being in improving the prediction of this health-risk behaviour. Future research will need to replicate and extend these preliminary findings before such a framework may be translated into an intervention targeting SF consumption.
Prevalence, incidence and mortality from cardiovascular disease in patients with pooled and specific severe mental illness: a large‐scale meta‐analysis of 3,211,768 patients and 113,383,368 controls

People with severe mental illness (SMI) – schizophrenia, bipolar disorder and major depressive disorder – appear at risk for cardiovascular disease (CVD), but a comprehensive meta‐analysis is lacking. We conducted a large‐scale meta‐analysis assessing the prevalence and incidence of CVD; coronary heart disease; stroke, transient ischemic attack or cerebrovascular disease; congestive heart failure; peripheral vascular disease; and CVD‐related death in SMI patients (N=3,211,768) versus controls (N=113,383,368) (92 studies). The pooled CVD prevalence in SMI patients (mean age 50 years) was 9.9% (95% CI: 7.4‐13.3). Adjusting for a median of seven confounders, patients had significantly higher odds of CVD versus controls in cross‐sectional studies (odds ratio, OR=1.53, 95% CI: 1.27‐1.83; 11 studies), and higher odds of coronary heart disease (OR=1.51, 95% CI: 1.47‐1.55) and cerebrovascular disease (OR=1.42, 95% CI: 1.21‐1.66). People with major depressive disorder were at increased risk for coronary heart disease, while those with schizophrenia were at increased risk for coronary heart disease, cerebrovascular disease and congestive heart failure. Cumulative CVD incidence in SMI patients was 3.6% (95% CI: 2.7‐5.3) during a median follow‐up of 8.4 years (range 1.8‐30.0). Adjusting for a median of six confounders, SMI patients had significantly higher CVD incidence than controls in longitudinal studies (hazard ratio, HR=1.78, 95% CI: 1.60‐1.98; 31 studies). The incidence was also higher for coronary heart disease (HR=1.54, 95% CI: 1.30‐1.82), cerebrovascular disease (HR=1.64, 95% CI: 1.26‐2.14), congestive heart failure (HR=2.10, 95% CI: 1.64‐2.70), and CVD‐related death (HR=1.85, 95% CI: 1.53‐2.24). People with major depressive disorder, bipolar disorder and schizophrenia were all at increased risk of CVD‐related death versus controls. CVD incidence increased with antipsychotic use (p=0.008), higher body mass index (p=0.008) and higher baseline CVD prevalence (p=0.03) in patients vs. controls. Moreover, CVD prevalence (p=0.007), but not CVD incidence (p=0.21), increased in more recently conducted studies. This large‐scale meta‐analysis confirms that SMI patients have significantly increased risk of CVD and CVD‐related mortality, and that elevated body mass index, antipsychotic use, and CVD screening and management require urgent clinical attention.
Influence of parental depressive symptoms on adopted toddler behaviors: An emerging developmental cascade of genetic and environmental effects

Abstract This study examined the developmental cascade of both genetic and environmental influences on toddlers' behavior problems through the longitudinal and multigenerational assessment of psychosocial risk. We used data from the Early Growth and Development Study, a prospective adoption study, to test the intergenerational transmission of risk through the assessment of adoptive mother, adoptive father, and biological parent depressive symptoms on toddler behavior problems. Given that depression is often chronic, we control for across-time continuity and find that in addition to associations between adoptive mother depressive symptoms and toddler externalizing problems, adoptive father depressive symptoms when the child is 9 months of age were associated with toddler problems and associated with maternal depressive symptoms. Findings also indicated that a genetic effect may indirectly influence toddler problems through prenatal pregnancy risk. These findings help to describe how multiple generations are linked through genetic (biological parent), timing (developmental age of the child), and contextual (marital partner) pathways.
Association of Attention Deficit Disorder With Bedside Anti-saccades in Survivors of Childhood Leukemia

Impaired attention is well recognized in childhood cancer survivors. We prospectively evaluated 162 long-term survivors of childhood acute lymphoblastic leukemia to study an association between presence of neurologic soft signs as measured by Zurich Neuromotor Scale, bedside evaluation of anti-saccades, and attention deficit disorder. Attention deficit disorder was recognized in 10.5% of the study cohort. We did not find an association of attention deficit with presence of any soft sign. However, there was an association between presence of abnormal anti-saccades and attention deficit (P = .04). These results will require further validation and if confirmed may introduce a quick bedside method of assessing impaired attention in cancer survivors.
Influence of oxygen on wound healing

Oxygen has an important role in normal wound healing. This article reviews the evidence concerning the role of oxygen in wound healing and its influence on the different stages of wound healing. The evidence reviewed has demonstrated that improving oxygenation may be helpful in limiting wound infection, although there is a lack of good quality studies on the role of oxygen in the proliferative phase and in reepithelialisation. Overall, the relationship between oxygen and wound healing is complex. Knowledge of this aspect is important as many treatment modalities for refractory wounds are based on these principles.
Growth and calcium metabolism in horses fed varying levels of protein.

The effect of level of protein intake on growth and calcium metabolism was studied in 24 foals. Starting at four months old, the foals were fed one of three diets containing all nutrients, with the exception of protein, at levels recommended by the United States National Research Council Subcommittee on Horse Nutrition for a 12 month period. The protein levels in the three diets were 9 per cent (low protein) 14 per cent (NRC recommended level) and 20 per cent (high protein). The foals fed the low protein diet were changed to the high protein diet after 140 days when they were nine months old. There were no significant differences in the rates of growth in weight, height, cannon circumference or in hoof growth and feed utilisation of the horses fed the 14 or the 20 per cent protein diets. However, growth, feed intake and feed utilisation by the foals fed the low (9 per cent) protein diet were significantly depressed. The average daily gains for the first 140 days for the 9, 14 and 20 per cent protein treatment groups were 64, 631 and 687 g in weight, 0.57, 0.83 and 0.87 mm in height and 0.04, 0.13 and 0.14 m in forecannon circumference, respectively. The average daily feed intakes for the 140 day period for the three groups were 2.7, 4.4 and 4.7 kg, respectively. After the change to the high protein diet the foals that had been fed the low protein diet maintained a higher rate of gain in bodyweight, height and cannon circumference, and utilised feed more efficiently than the other two groups throughout the second 140 days of the experiment.

An alternative technique for the computation of the designator in the retinex theory of color vision.

Accepting the first postulate of the retinex theory of color vision that there are three independent lightness-determining mechanisms (one for long waves, one for middle waves, and one for short waves), each operative with less than a millisecond exposure and each served by its own retinal pigment, a basic task of retinex theory becomes the determination of the nature of these mechanisms. Earlier references proposed several workable algorithms. [Land, E. H. (1959) Proc. Natl. Acad. Sci. USA 45, 115-129; Land, E. H. (1959) Proc. Natl. Acad. Sci. USA 45, 636-644; Land, E. H. (1983) Proc. Natl. Acad. Sci. USA 80, 5163-5169; Land, E. H. & McCann, J. J. (1971) J. Opt. Soc. Am. 61, 1-11; Land, E. H. (1986) Vision Res. 26, 7-21. ] The present paper describes a relatively simple alternative technique for the computation of the designator in retinex theory and reports the general operational effectiveness of the new technique, including the competence, not possessed by earlier algorithms, for generating Mach bands.
Personality disorder traits, family environment, and alcohol misuse: a multivariate behavioural genetic analysis.

AIMS This study seeks to estimate the extent to which a common genetic and environmental basis is shared between (i) traits delineating specific aspects of antisocial personality and alcohol misuse, and (ii) childhood family environments, traits delineating broad domains of personality pathology and alcohol misuse. DESIGN Postal survey data were collected from monozygotic and dizygotic twin pairs. SETTING Twin pairs were recruited from Vancouver, British Columbia and London, Ontario, Canada using newspaper advertisements, media stories and twin clubs. PARTICIPANTS Data obtained from 324 monozygotic and 335 dizygotic twin pairs were used to estimate the extent to which traits delineating specific antisocial personality traits and alcohol misuse shared a common genetic and environmental aetiology. Data from 81 monozygotic and 74 dizygotic twin pairs were used to estimate the degree to which traits delineating personality pathology, childhood family environment and alcohol misuse shared a common aetiology. MEASUREMENTS Current alcohol misuse and personality pathology were measured using scales contained in the self-report Dimensional Assessment of Personality Pathology. Perceptions of childhood family environment were measured using the self-report Family Environment Scale. FINDINGS Multivariate genetic analyses showed that a subset of traits delineating components of antisocial personality (i.e. grandiosity, attention-seeking, failure to adopt social norms, interpersonal violence and juvenile antisocial behaviours) are influenced by genetic factors in common to alcohol misuse. Genetically based perceptions of childhood family environment had little relationship with alcohol misuse. CONCLUSIONS Heritable personality factors that influence the perception of childhood family environment play only a small role in the liability to alcohol misuse. Instead, liability to alcohol misuse is related to genetic factors common a specific subset of antisocial personality traits describing conduct problems, narcissistic and stimulus-seeking behaviour.
Reliability of perceived neighbourhood conditions and the effects of measurement error on self-rated health across urban and rural neighbourhoods

Background Limited psychometric research has examined the reliability of self-reported measures of neighbourhood conditions, the effect of measurement error on associations between neighbourhood conditions and health, and potential differences in the reliabilities between neighbourhood strata (urban vs rural and low vs high poverty). We assessed overall and stratified reliability of self-reported perceived neighbourhood conditions using five scales (social and physical disorder, social control, social cohesion, fear) and four single items (multidimensional neighbouring). We also assessed measurement error-corrected associations of these conditions with self-rated health. Methods Using random-digit dialling, 367 women without breast cancer (matched controls from a larger study) were interviewed twice, 2–3 weeks apart. Test–retest (intraclass correlation coefficients (ICC)/weighted κ) and internal consistency reliability (Cronbach's α) were assessed. Differences in reliability across neighbourhood strata were tested using bootstrap methods. Regression calibration corrected estimates for measurement error. Results All measures demonstrated satisfactory internal consistency (α≥0.70) and either moderate (ICC/κ=0.41–0.60) or substantial (ICC/κ=0.61–0.80) test–retest reliability in the full sample. Internal consistency did not differ by neighbourhood strata. Test–retest reliability was significantly lower among rural (vs urban) residents for two scales (social control, physical disorder) and two multidimensional neighbouring items; test–retest reliability was higher for physical disorder and lower for one multidimensional neighbouring item among the high (vs low) poverty strata. After measurement error correction, the magnitude of associations between neighbourhood conditions and self-rated health were larger, particularly in the rural population. Conclusion Research is needed to develop and test reliable measures of perceived neighbourhood conditions relevant to the health of rural populations.
IL-10 Deficiency Promotes Increased Borrelia burgdorferi Clearance Predominantly through Enhanced Innate Immune Responses1

Borrelia burgdorferi is capable of persistently infecting a variety of hosts despite eliciting potent innate and adaptive immune responses. Preliminary studies indicated that IL-10-deficient (IL-10−/−) mice exhibit up to 10-fold greater clearance of B. burgdorferi from target tissues compared with wild-type mice, establishing IL-10 as the only cytokine currently known to have such a significant effect on spirochetal clearance. To further delineate these IL-10-mediated immune effects, kinetic studies indicated that spirochete dissemination to target tissues is similar in both wild-type and IL-10−/− mouse strains, and that enhanced clearance of B. burgdorferi in IL-10−/− mice is correlated with increased B. burgdorferi-specific Ab as early as 2 wk postinfection. Immunoblot analysis indicated that Abs produced by infected IL-10−/− and wild-type mice recognize similar ranges of spirochetal Ags. Immune sera from IL-10−/− and wild-type mice also exhibited similar bactericidal activity in vitro, and passive transfer of these immune sera into B. burgdorferi-infected SCID mice caused similar reductions of bacterial numbers in target tissues. Infectious dose studies indicated that 8-fold more B. burgdorferi were needed to efficiently infect naive IL-10−/− mice, suggesting these animals possess higher innate barriers to infection. Moreover, macrophages derived from IL-10−/− mice exhibit enhanced proinflammatory responses to B. burgdorferi stimulation compared with wild-type controls, and these responses are not significantly affected by the presence of immune serum. These findings confirm that B. burgdorferi clearance by innate immune responses is more efficient in the absence of IL-10, and these activities are not directly related to increased levels of B. burgdorferi-specific Ab.
Detection and characterization of focal liver lesions by split-bolus multidetector-row CT: diagnostic accuracy and radiation dose in oncologic patients.

AIM To assess the diagnostic accuracy and radiation dose of split-bolus multidetector-row computed tomography (MDCT) protocol in the detection and characterization of focal liver lesions in oncologic patients. PATIENTS AND METHODS We retrospectively analyzed triphasic CT at initial diagnosis and follow-up split-bolus 64-detector row CT protocol in 48 oncologic patients with focal liver lesions. Split-bolus MDCT protocol by i.v. injection of two boli of contrast medium combines hepatic arterial phase (HAP) and hepatic enhancement during portal venous phase (PVP) in a single pass. First bolus: 75-90 mL at 2.0 mL/sec to obtain adequate hepatic enhancement during the PVP; second bolus: 60 mL/sec at 3.5 mL/sec to ensure HAP. Each bolus is followed by 20 mL of saline solution at the same flow rate. Sensitivity, specificity, positive predictive value and negative predictive value of split-bolus MDCT protocol were calculated for detection and characterization of liver lesions. The effective radiation dose (ED) was calculated using dose-length product (DLP) values in mSv determined using a conversion factor. RESULTS compared to triphasic-MDCT, split-bolus MDCT protocol confirmed all the 210 lesions identified and characterized by triphasic-MDCT technique, unchanged during the follow-up. The mean ED was 27.8 ± 6 mSv for chest-abdomen-pelvis biphasic split-bolus MDCT and 45.7 ± 13.6 mSv for triphasic-MDCT. CONCLUSION The diagnostic efficacy of split-bolus protocol is comparable to that of triphasic protocol at MDCT with a reduction in radiation dose of approximately 35-40%.
Web-based proactive system to improve breast cancer screening: a randomized controlled trial.

BACKGROUND Screening mammography is recommended for early detection of breast cancer but screening rates remain suboptimal. METHODS A primary care portal for a large academic primary practice was developed for all preventive services. Another Web-based system (PRECARES [PREventive CAre REminder System]) was developed for appointment secretaries to manage proactive breast cancer screening. Female patients aged 40 to 75 years were randomly assigned to a control group (usual care) and an intervention group. For the intervention group, 2 monthly letters inviting patients to undergo mammography were sent starting 3 months before they were due for annual screening, followed by a telephone call to nonresponding patients. A subgroup of women employees was further randomized to receive a reminder by either US mail or e-mail. RESULTS Of the total eligible population of 6665 women identified as having consented to participate in research, 3339 were randomly assigned to the control group and 3326 to the intervention group. The screening rate for annual mammography was 64.3% for the intervention group and 55.3% for the control group (P <.001). There were no significant differences between the 2 groups for any of the other adult preventive services. For the employee subgroup, the screening rate was 57.5% for the control group, 68.1% for the US mail group, and 72.2% for the e-mail group (intervention vs control, P <.001; e-mail vs US mail; P = .24). CONCLUSION The breast cancer screening rate improved significantly with the practice redesign of having appointment secretaries proactively manage breast cancer screening needs.
Sleep schedules and daytime functioning in adolescents.

Sleep and waking behaviors change significantly during the adolescent years. The objective of this study was to describe the relation between adolescents' sleep/wake habits, characteristics of students (age, sex, school), and daytime functioning (mood, school performance, and behavior). A Sleep Habits Survey was administered in homeroom classes to 3,120 high school students at 4 public high schools from 3 Rhode Island school districts. Self-reported total sleep times (school and weekend nights) decreased by 40-50 min across ages 13-19, ps < . 001. The sleep loss was due to increasingly later bedtimes, whereas rise times were more consistent across ages. Students who described themselves as struggling or failing school (C's, D's/F's) reported that on school nights they obtain about 25 min less sleep and go to bed an average of 40 min later than A and B students, ps < . 001. In addition, students with worse grades reported greater weekend delays of sleep schedule than did those with better grades. Furthermore, this study examined a priori defined adequate sleep habit groups versus less than adequate sleep habit groups on their daytime functioning. Students in the short school-night total sleep group (< 6 hr 45 min) and/or large weekend bedtime delay group (> 120 min) reported increased daytime sleepiness, depressive mood, and sleep/wake behavior problems, ps < . 05, versus those sleeping longer than 8 hr 15 min with less than 60 min weekend delay. Altogether, most of the adolescents surveyed do not get enough sleep, and their sleep loss interferes with daytime functioning.
Stimulation of Small Proteoglycan Synthesis by the Hyaluronan Synthesis Inhibitor 4-Methylumbelliferone in Human Skin Fibroblasts

Human skin fibroblasts cultured with 4-methylumbelliferone (MU), a hyaluronan synthesis inhibitor, produce a hyaluronan-deficient extracellular matrix (See []). Our present study investigated the effects of MU on proteoglycan, which is the other main component of the extracellular matrix, and interacts with hyaluronan. Proteoglycans isolated from culture medium in the presence or absence of MU were characterized by gel-filtration chromatography, ion-exchange HPLC, electrophoresis, and immunoblotting. We found that MU had only a negligible effect on the synthesis of large proteoglycan but increased the production of small proteoglycan in comparison with cultures lacking MU. This small proteoglycan was identified by immunoblotting as decorin. The structures of decorin synthesized in the presence and absence of MU were compared by gel-filtration chromatography, and the data indicated that cells incubated with MU produced a larger decorin molecule than cells incubated without MU. Furthermore, the two decorins had galactosaminoglycan chains of different sizes. These results suggest that MU inhibits the synthesis of hyaluronan and accelerates production of the larger decorin in the extracellular matrix.
Outcomes, Incentives, and Beliefs: Reflections on Analysis of the Economics of Schools

performance can be improved. This perspectiveat least as applied-may be a bit narrow, although I think it is central to much of the policy discussion in education. Overall, I believe that this research line is poised to improve educational policymaking, but much of its potential depends on developments yet to come. As I reflect on the development of policy analysis in education, four aspects stand out. The first involves a transformation of approach that is now deeply embedded in the fabric of analysis and unlikely to go away. This transformation centers on the now-obligatory concern with observed performance and student outcomes. The second is the
