Abstract
BACKGROUND To address nutrition-related population mental health data gaps, we examined relationships among food insecurity, diet quality, and perceived mental health. METHODS Stratified and logistic regression analyses of respondents aged 19-70 years from the Canadian Community Health Survey, Cycle 2.2 were conducted (n = 15,546). Measures included the Household Food Security Survey Module, diet quality (i.e., comparisons to the Dietary Reference Intakes, Healthy Eating Index), perceived mental health (poor versus good), sociodemographics, and smoking. RESULTS In this sample, 6.9% were food insecure and 4.5% reported poor mental health. Stratified analysis of food security and mental health status by age/gender found associations for poor diet quality, protein, fat, fibre, and several micronutrients (p-values < 0.05); those who were food insecure tended to have higher suboptimal intakes (p-values < 0.05). After adjustment for covariates, associations in relation to mental health emerged for food insecurity (OR = 1.60, 95% CI 1.45-1.71), poor diet quality (1.61, 95% CI 1.34-1.81), and suboptimal intakes of folate (OR = 1.58, 95% CI 1.17-1.90) and iron (OR = 1.45, 95% CI 1.23-1.88). CONCLUSIONS Population approaches that improve food security and intakes of high quality diets may protect people from poor mental health.

Abstract
IMPORTANCE Hemorrhage into the brain of term newborns often results in major injury and lifelong disability. The clinical epidemiology of neonatal hemorrhagic stroke (NHS) remains undefined, hindering the development of strategies to improve outcomes. OBJECTIVE To characterize the incidence, types, presentations, associated factors, and outcomes of neonatal hemorrhagic stroke. DESIGN, SETTING, AND PARTICIPANTS Population-based, nested case-control study. The Alberta Perinatal Stroke Project, a provincial registry, ascertained NHS cases using exhaustive diagnostic code searching (1992-2010, >2500 medical record reviews). Prospective cases were captured through the Calgary Pediatric Stroke Program (2007-2014). Participants included term neonates with magnetic resonance imaging-confirmed NHS including primary and secondary intracerebral hemorrhage, hemorrhagic transformation of ischemic injury, and presumed perinatal hemorrhagic stroke. Control infants with common data were recruited from a population-based study (4 to 1 ratio). MAIN OUTCOMES AND MEASURES Infants with NHS underwent structured medical record review using data-capture forms and blinded scoring of neuroimaging. Clinical risk factor common data elements were explored using logistic regression. Provincial live births were obtained from Statistics Canada. Outcomes were extrapolated to the Pediatric Stroke Outcome Measure. RESULTS We identified 86 cases: 51 infants (59%) with NHS, of which 32 (67%) were idiopathic, 30 (35%) were hemorrhagic transformation of primary ischemic injuries (14 with neonatal cerebral sinovenous thrombosis, 11 with hypoxic ischemic encephalopathy, and 5 with neonatal arterial ischemic stroke), and 5 were presumed perinatal hemorrhagic stroke. Sixty-two percent were male. Incidence of pure NHS was 1 in 9500 live births and 1 in 6300 for all forms. Most presented in the first week of life with seizures and encephalopathy. Acute neurosurgical intervention was rare (3 of 86 total cases; 3.5%). Temporal lobe was the most common NHS location (16 of 51 pure NHS cases; 31%). A primary cause was evident in 19 of the 51 cases of non-hemorrhagic transformation NHS (37%). Idiopathic NHS was independently associated with lower maternal age (odds ratio [OR], 0.87; 95% CI, 0.78-0.94), primiparity (OR, 2.98; 95% CI, 1.18-7.50), prior spontaneous abortion (OR, 0.11; 95% CI, 0.02-0.53), difficult fetal transition (bradycardia [OR, 15.0; 95% CI, 2.19-101.9] and low Apgar [OR, 14.3; 95% CI, 2.77-73.5]), and small for gestational age (OR, 14.3; 95% CI, 1.62-126.1). Follow-up of 50 cases at a median of 37 months demonstrated poor neurological outcomes in 21 patients (44%). CONCLUSIONS AND RELEVANCE Neonatal hemorrhagic stroke is more common than previously reported, occurring in at least 1 in 6300 live births. Etiologies are approximately equally distributed between idiopathic, secondary, and hemorrhagic transformation. Clinical associations do not suggest a common mechanism or predictability of NHS. Recurrence is rare. Outcomes are often poor, mandating attention to prevention and rehabilitation.

Abstract
Background Healthcare costs are skyrocketing, with mental health treatment amongst the most expensive, especially when hospitalization is involved. According to the Mental Health Commission of Canada, one in five Canadians is living with a mental disorder in any given year, at an annual cost of $50 billion. In light of this societal burden, alternative approaches are being evaluated, such as brief psychotherapy by phone, peer support, and, as part of the emerging field of nutritional mental health, treatment with micronutrients (minerals and vitamins). Effectiveness of micronutrients has been demonstrated for many types of psychiatric symptoms, in about 45 studies of formulas that are either multinutrient (e.g., several B vitamins) or broad-spectrum (usually over 20 minerals and vitamins). Although this literature demonstrates therapeutic benefits, the potential economic impact of micronutrient treatment has been evaluated in only one case study of childhood psychosis. Methods The current case study was initiated to evaluate mental health-related hospitalization costs from 1997 to 2003 for a female adult diagnosed with various mood and psychotic symptoms. She was treated for the first 5 years with conventional methods and then subsequently with a broad-spectrum micronutrient formula. Results The patient’s annual mental health hospitalization costs during conventional treatment averaged $59,864 across 5 years (1997–2001), with a peak annual cost of about $140,000. Since transitioning to broad-spectrum micronutrients, she has incurred no provincial hospitalization costs for mental health care, though her self-funded costs are currently $720/year for the micronutrients. Conclusion Further exploration of the treatment of mental health problems with broad-spectrum micronutrient formulas has the potential to make two significant contributions: improved mental health, and decreased costs for governments.

Abstract
BACKGROUND Perinatal maternal depression is a serious health concern with potential lasting negative consequences for children. Prenatal depression is associated with altered brain gray matter in children, though relations between postpartum depression and children's brains and the role of white matter are unclear. METHODS We studied 52 women who provided Edinburgh Postnatal Depression Scale (EPDS) scores during each trimester of pregnancy and at 3 months postpartum and their children who underwent magnetic resonance imaging at age 2.6 to 5.1 years. Associations between maternal depressive symptoms and magnetic resonance imaging measures of cortical thickness and white matter structure in the children were investigated. RESULTS Women's second trimester EPDS scores negatively correlated with children's cortical thickness in right inferior frontal and middle temporal regions and with radial and mean diffusivity in white matter emanating from the inferior frontal area. Cortical thickness, but not diffusivity, correlations survived correction for postpartum EPDS. Postpartum EPDS scores negatively correlated with children's right superior frontal cortical thickness and with diffusivity in white matter originating from that region, even after correcting for prenatal EPDS. CONCLUSIONS Higher maternal depressive symptoms prenatally and postpartum are associated with altered gray matter structure in children; the observed white matter correlations appear to be uniquely related to the postpartum period. The reduced thickness and diffusivity suggest premature brain development in children exposed to higher maternal perinatal depressive symptoms. These results highlight the importance of ensuring optimal women's mental health throughout the perinatal period, because maternal depressive symptoms appear to increase children's vulnerability to nonoptimal brain development.

Abstract
Ayres' seminal paper in 1972 reported that Sensory Integration (SI) Treatment was a promising method for improving the academic scores of children with learning disabilities. Ottenbacher's (1982a) review of research reported during that first decade indicated that SI treatment was worthy of further investigation. In this report, we reviewed randomized, controlled trials conducted primarily in the second decade, and conclude that the status of the literature 20 years after Ayres' original article does not support SI treatment as an effective treatment for the academic problems of learning disabled children. With respect to sensory or motor variables, it is not clear whether or not SI treatment is more effective than perceptual-motor approaches. Future research also must determine whether SI treatment is more effective than maturation alone.

Abstract
Following the completion of a study of the efficacy of sensory integration (SI) treatment compared with tutoring, the question raised was whether a greater difference between the two groups would exist after a period of time had elapsed after treatment ended. Twenty-two of the original 29 subjects completed follow-up assessment two years after the completion of their treatment. Only one significant difference between the two groups was seen at follow-up: The gross motor performance of the group who received SI treatment was significantly greater than that of children who received tutoring. There was no difference between the groups on measures of reading skills, fine motor skills, visual motor skills, or behavioral factors. There were no significant correlations between the amount of improvement a child made during treatment and the maintenance of the gains.

Abstract
BACKGROUND Vitamin D is critical for healthy pregnancies and normal fetal development. It is important to accurately ascertain vitamin D status in mothers and their newborns to establish the optimal vitamin D concentration during pregnancy. There are many different metabolites and epimers of vitamin D in peripheral blood and controversy as to the importance of epimers in estimating vitamin D status in maternal and infant health. OBJECTIVES We undertook this study to measure 25-hydroxyvitamin D metabolites and epimers and their relations in maternal and cord blood and to evaluate the impact of the inclusion of epimers on assessing vitamin D status. METHODS We performed a substudy in a longitudinal cohort of pregnant women and their infants in Alberta, Canada [APrON (Alberta Pregnancy Outcomes and Nutrition) Study]. Maternal and cord blood plasma collected at the time of newborn delivery was stored at -70°C until testing and assayed for 25-hydroxyergocalciferol [25(OH)D2], 25-hydroxycholecalciferol [25(OH)D3], and 3-epi-25-hydroxycholecalciferol [3-epi-25(OH)D3] by using LC-tandem mass spectrometry. The effect of 3-epi-25(OH)D3 on estimates of vitamin D adequacy was explored by using McNemar's chi-square test at both recommended thresholds of 50 and 75 nmol/L. RESULTS Ninety-two pairs of maternal and cord blood samples were obtained. 3-Epi-25(OH)D3 was detected in all samples, comprising 6.0% and 7.8% of 25(OH)D3 in maternal and cord blood, respectively. Positive correlations were found between 25(OH)D3 and 3-epi-25(OH)D3 for both maternal and cord blood (maternal blood: r = 0.34, P = 0.01; cord blood: r = 0.44, P = 0.01). In addition, regression analysis showed a significant association between vitamin D supplementation and 3-epi-25(OH)D3 in maternal and cord blood (β: 0.423; 95% CI: 0.173, 0.672). When 3-epi-25(OH)D3 was not included in plasma vitamin D estimations, 38% of women and 80% of neonates were classified as having an insufficient concentration (<75 nmol/L); however, with 3-epi-25(OH)D3 included, the estimates of insufficiency were significantly lower: 33% and 73% for women and neonates, respectively. CONCLUSIONS Using LC-MS/MS we showed the presence of 3-epi-25(OH)D3 in all samples of pregnant women and their cord blood, and when the 3-epimer was included in the estimation of status the prevalence of vitamin D insufficiency (<75 nmol/L) was significantly lower. Our data suggest that the high use of dietary supplements in this group of women contributes to 3-epi-25(OH)D3 concentrations in both maternal and cord blood. Further research on the role of the epimers in characterizing vitamin D status in pregnancy and infancy is imperative.

Abstract
INTRODUCTION In clinical studies of adults and children, broad-spectrum micronutrients (minerals and vitamins) have proven beneficial for improving mood regulation and attention. We report here pilot work whose primary objective was to evaluate the feasibility of studying micronutrient treatment in school-aged children with emotional and behavioral problems. Issues examined included feasibility of participant recruitment from a culturally diverse population, probability of sample retention for a 12-week trial, acceptability of the outcome measures, supplement adherence, as well as trends in treatment benefit. CASE PRESENTATION The families of two boys (ages 5 and 6) and one girl (age 14) were invited to participate in a 12-week pilot trial of micronutrients carried out during the summer months. All children were enrolled in the private school at which future research was being considered. During the previous school year, all three had been extremely difficult to educate due to their inability to pay attention and learn, as well as their behavior problems. Although the two younger children had not been formally diagnosed, parents and teachers provided reports of hyperactivity and inability to focus on education in the classroom. The oldest child was often aggressive, and had been diagnosed with bipolar disorder, attention deficit hyperactivity disorder, and oppositional defiant disorder. All three children were Hispanic and spoke both Spanish and English. For 12 weeks, after signing consent forms, the children's parents provided weekly ratings on the parent-report Child Mania Rating Scale; the children consumed the micronutrient formula daily and provided a daily rating of how they felt. The parent ratings revealed significantly improved behavior, p = .002. Children's ratings approached the ideal level of 7, indicating "happy" self-reports. Parent interviews confirmed the weekly scores. Several feasibility questions were answered: all three children completed the 12-week trial, all scores were completed by parents and children, adherence to the protocol was excellent, and no adverse reactions emerged. CONCLUSIONS Family physicians and pediatricians are often confronted with the challenge of improving the lives of families whose children experience school crises due to emotional and behavioral dysregulation. Three children, who participated in pilot work to determine the feasibility of further investigations, experienced impressive changes that clearly warrant both research and clinical exploration.

Abstract
After devastating flooding in southern Alberta in June 2013, we attempted to replicate a New Zealand randomised trial that showed that micronutrient (minerals, vitamins) consumption after the earthquakes of 2010-11 resulted in improved mental health. Residents of southern Alberta were invited to participate in a study on the potential benefit of nutrient supplements following a natural disaster. Fifty-six adults aged 23-66 were randomised to receive a single nutrient (vitamin D, n=17), a few-nutrients formula (B-Complex, n=21), or a broad-spectrum mineral/vitamin formula (BSMV, n=18). Self-reported changes in depression, anxiety and stress were monitored for six weeks. Although all groups showed substantial decreases on all measures, those consuming the B-Complex and the BSMV formulas showed significantly greater improvement in stress and anxiety compared with those consuming the single nutrient, with large effect sizes (Cohen's d range 0.76-1.08). There were no group differences between those consuming the B-Complex and BSMV. The use of nutrient formulas with multiple minerals and/or vitamins to minimise stress associated with natural disasters is now supported by three studies. Further research should be carried out to evaluate the potential population benefit that might accrue if such formulas were distributed as a post-disaster public health measure.

Abstract
BACKGROUND AND AIMS Women with inflammatory bowel disease (IBD) may be at higher risk of adverse pregnancy outcomes. This study compared perinatal outcomes in women with and without IBD. METHODS The population-based Data Integration, Measurement, and Reporting (DIMR) administrative discharge database was used to identify women (≥18 years of age) in Alberta, Canada, with IBD who delivered a baby between 2006 and 2009 inclusive. Women without IBD were randomly sampled and matched in a 3:1 ratio to IBD cases by age at conception (±1 year). Odds ratios of gestational diabetes, preterm birth, low birth weight, cesarean section, and neonatal intensive care unit admission were calculated. RESULTS One hundred and sixteen IBD patients were age-matched to 381 pregnant women without IBD. Gestational diabetes, preterm birth, and cesarean section were more common in women with IBD compared with controls (6.9 versus 1.8%, p = 0.03; 12.9 versus 0.3%, p < 0.0001; 43.1 versus 21.0%, p = 0.009, respectively). On multivariate analysis, women with IBD were independently more likely to have gestational diabetes (odds ratio [OR] = 4.3; 95% confidence interval [CI] 1.2-16.3), preterm birth (OR = 19.7, 95% CI 2.2-173.9), and to deliver by cesarean section (OR = 2.7, 95% CI 1.6-4.6) after adjusting for age and smoking status. CONCLUSION Intrapartum corticosteroid use significantly increases the risk of gestational diabetes in women with IBD. Furthermore, IBD patients are at higher risk of preterm delivery and are more likely to undergo cesarean section compared with a healthy age-matched population. The finding of a higher risk of gestational diabetes is a novel finding not previously reported in the IBD literature.

Abstract
BACKGROUND Because little is known about food insecurity in people with mental health conditions, we investigated relationships among food insecurity, nutrient intakes, and psychological functioning in adults with mood disorders. METHODS Data from a study of adults randomly selected from the membership list of the Mood Disorder Association of British Columbia (n = 97), Canada, were analyzed. Food insecurity status was based on validated screening questions asking if in the past 12 months did the participant, due to a lack of money, worry about or not have enough food to eat. Nutrient intakes were derived from 3-day food records and compared to the Dietary Reference Intakes (DRIs). Psychological functioning measures included Global Assessment of Functioning, Hamilton Depression scale, and Young Mania Rating Scale. Using binomial tests of two proportions, Mann-Whitney U tests, and Poisson regression we examined: (1) food insecurity prevalence between the study respondents and a general population sample from the British Columbia Nutrition Survey (BCNS; n = 1,823); (2) differences in nutrient intakes based on food insecurity status; and (3) associations of food insecurity and psychological functioning using bivariate and Poisson regression statistics. RESULTS In comparison to the general population (BCNS), food insecurity was significantly more prevalent in the adults with mood disorders (7.3% in BCNS vs 36.1%; p < 0.001). Respondents who were food-insecure had lower median intakes of carbohydrates and vitamin C (p < 0.05). In addition, a higher proportion of those reporting food insecurity had protein, folate, and zinc intakes below the DRI benchmark of potential inadequacy (p < 0.05). There was significant association between food insecurity and mania symptoms (adjusted prevalence ratio = 2.37, 95% CI 1.49-3.75, p < 0.05). CONCLUSIONS Food insecurity is associated with both nutritional and psychological health in adults with mood disorders. Investigation of interventions aimed at food security and income can help establish its role in enhancing mental health.

Abstract
Background Probiotic products that may modify the intestinal microbiota are becoming increasingly available and known to consumers due to their potential to prevent or treat many pediatric health conditions. As scientific knowledge of the health benefits of probiotics increases, it is important to identify factors that may prevent their successful integration into patient care as well as to ensure effective translation of research findings. The aim of this study was to describe maternal perspectives on probiotics and their use in infants. Methods Mothers with a child aged two years or younger enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study were invited by email to complete a 29 item self-administered web-based questionnaire. Results A total of 413 mothers of the 1327 contacted completed the questionnaire. The majority (99.3%) of respondents had heard of probiotics and were aware that they contained live bacteria (87.0%); 89.3% had used a product containing probiotics themselves but only 50.8% had given one to their infant. Most mothers indicated they believed that probiotics were beneficial (73.1%) and none thought they were harmful. Over a third of mothers did not feel informed enough to make a decision on whether probiotics were safe to use in infants (36.6%). Conclusions The study demonstrates that awareness and understanding of probiotics is high among mothers in Alberta, Canada. However, there is still uncertainty regarding the benefit of probiotics as well as safety in infants which could be important factors determining therapeutic use in the future. Further studies that demonstrate beneficial effects and safety of probiotics in healthy infants as well as targeted knowledge translation should help to address these potential concerns.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a chronic psychiatric illness, which often co-occurs with other common psychiatric problems. Although empirical evidence supports the short-term efficacy of pharmacological and behavioural treatments, families often search for alternative treatment methods because of concerns about side effects and safety, cost and access, as well as fears about long-term exposure to psychotropic medications. This review presents the published evidence on use of broad-spectrum micronutrients to treat ADHD symptoms. This approach makes physiological sense in that nutrients are required for many critical biochemical reactions to occur, ranging from manufacturing neurotransmitters, to providing the mitochondria with essential nutrients for energy production, to assisting the gut to heal from inflammation. Multi-nutrient treatment approaches are an intriguing yet under-researched area; all but one of the trials conducted in the last decade have shown benefit for the treatment of ADHD symptoms, and the one negative trial likely used doses too low to effect change. However, the methodologies have varied widely from case-controlled studies to open-label trials to one randomized controlled trial. Sample sizes have typically been modest, although the effect sizes have tended to be medium to large. What is required now is replication, as well as investigation into the optimal ingredient range and optimal doses of nutrients. We discuss the proven and potential benefits of the broad-spectrum nutrient approach, considering the heterogeneous nature of ADHD.

Abstract
Background: Mood disorders are associated with a high risk of suicide. Statin therapy has been implicated in this relationship. Aims: To further clarify reported associations between suicide and cholesterol in mental health conditions, we conducted an analysis of dietary, clinical, and suicidal ideation measures in community-living adults with mood disorders. Method: Data were used from a cross-sectional study of a randomly selected community-based sample (> 18 years; n = 97) with verified mood disorders. Dietary (e.g., fat, iron, vitamin intakes), clinical (e.g., current depression and mania symptoms, medications), and sociodemographic (age, sex, and income) measures were analyzed using bivariate statistics and Poisson regression with robust variance. Results: Participants were predominantly female (71.1%) with bipolar disorder (59.8%); almost one-third (28.9%) were taking lipophilic statins. The prevalence of suicidal ideation was more than 2.5 times in those taking statins, PR = 2.59, 95% CI 1.27–5.31, p < .05. The prevalence ratio for suicidal ideation was 1.10, 95% CI 1.06–1.15, p < .001, for each unit increase in mania symptom scores. No associations between suicidal ideation and dietary intake measures were identified. Conclusion: Individuals with mood disorders may be susceptible to neuropsychiatric effects of cholesterol-lowering drugs, which warrants further research.

Abstract
Background Head position practice has been shown to influence pill-swallowing ability, but the impact of head position on measures of swallowing outcomes has not yet been studied with fiber-optic endoscopic evaluation of swallowing (FEES). The primary purpose of this study was to determine whether head position impacts penetration-aspiration scale scores and/or post-swallow pharyngeal residue as assessed by FEES. Documenting the incidence of pharyngeal residue and laryngeal penetration and aspiration in a normal population was a secondary goal. Methods Adults without swallowing difficulties (N = 84) were taught a pill swallowing technique based on learning five head positions and were asked to practice with small, hard candies (e.g., TicTacs) for two weeks. Then they demonstrated swallowing in each of the head positions for two conditions, liquid and purée, while undergoing FEES. Results Out of 840 examined swallows, one event of aspiration and 5 events of penetration occurred. During practice >50% participants found positions they preferred over the center position for swallowing but head position was not associated with penetration-aspiration scores assessed by FEES. Significant associations and non-significant trends were found between pharyngeal residue and three variables: age, most preferred head position, and least preferred head position. Conclusion Head position during swallowing (head up) and age greater than 40 years may result in increased pharyngeal residue but not laryngeal penetration or aspiration.

Abstract
Background One of the biggest challenges for population health studies is the recruitment of participants. Questions that investigators have asked are “who volunteers for studies?” and “does recruitment method influence characteristics of the samples?” The purpose of this paper was to compare sample characteristics of two unrelated pregnancy cohort studies taking place in the same city, in the same time period, that employed different recruitment strategies, as well as to compare the characteristics of both cohorts to provincial and national statistics derived from the Maternity Experiences Survey (MES). Methods One pregnancy cohort used community-based recruitment (e.g. posters, pamphlets, interviews with community media and face-to-face recruitment in maternity clinics); the second pregnancy cohort used both community-based and population-based (a centralized system identifying pregnant women undergoing routine laboratory testing) strategies. Results The pregnancy cohorts differed in education, income, ethnicity, and foreign-born status (p < 0.01), but were similar for maternal age, BMI, and marital status. Compared to the MES, the lowest age, education, and income groups were under-represented, and the cohorts were more likely to be primiparous. Conclusions The findings suggest that non-stratified strategies for recruitment of participants will not necessarily result in samples that reflect the general population, but can reflect the target population of interest. Attracting and retaining young, low resource women into urban studies about pregnancy may require alternate and innovative approaches.

Abstract
OBJECTIVE Recent studies suggest that effective social support during pregnancy may buffer adverse effects of maternal psychological distress on fetal development. The mechanisms whereby social support confers this protective advantage, however, remain to be clarified. The aim of this study was to assess whether individual differences in social support alter the covariation of psychological distress and cortisol during pregnancy. METHODS Eighty-two pregnant women's psychological distress and cortisol were prospectively assessed in all three trimesters using an ecological momentary assessment strategy. Appraisal of partner social support was assessed in each trimester via the Social Support Effectiveness questionnaire. RESULTS In multilevel analysis, ambulatory assessments of psychological distress during pregnancy were associated with elevated cortisol levels (unstandardized β = .023, p < .001). Consistent with the stress-buffering hypothesis, social support moderated the association between psychological distress and cortisol (unstandardized β = -.001, p = .039), such that the covariation of psychological distress and cortisol increased with decreases in effective social support. The effect of social support for women with the most effective social support was a 50.4% reduction in the mean effect of distress on cortisol and a 2.3-fold increase in this effect for women with the least effective social support scores. CONCLUSIONS Pregnant women receiving inadequate social support secrete higher levels of cortisol in response to psychological distress as compared with women receiving effective social support. Social support during pregnancy may be beneficial because it decreases biological sensitivity to psychological distress, potentially shielding the fetus from the harmful effects of stress-related increases in cortisol.

Abstract
BACKGROUND Clinics often encounter neurologically intact patients who are unable to swallow pills. All of the interventions published previously have used traditional behavioural techniques, which are time consuming and often not helpful. OBJECTIVE To determine whether children who had never been able to swallow a whole pill could become successful as a result of an intervention based on head posture. METHOD A novel intervention was developed based on published research showing that changing head position alters swallowing dynamics. The method was developed in two studies of 240 adults and children, pilot tested in a study of 108 university students with very mild pill-swallowing discomfort, and then evaluated in a study of 41 children who had never successfully swallowed a pill in spite of much instruction and coaxing. Children were recruited from a tertiary paediatric hospital: 34 were clinic patients, four were their siblings or friends, and three were children of hospital staff. The primary intervention involved teaching five head positions (centre, up, down, left and right) followed by a two-week period of daily practice. RESULTS EIGHT CHILDREN (ALL CLINIC REFERRALS) WITHDREW WITHOUT PRACTICING: four were too ill to practice (primarily due to sedation or nausea) and four simply refused to do the homework practice. All 33 of the children who were able and willing to practice daily were successful. CONCLUSION Practice with head posture variations was successful in treating pill-swallowing difficulties in all 33 children who practiced for 14 days.

Abstract
BACKGROUND To address knowledge gaps regarding natural health product (NHP) usage in mental health populations, we examined their use in adults with mood disorders, and explored the potential for adverse events. METHODS Food and NHP intake was obtained from 97 adults with mood disorders. NHP data was used to compare prevalence with population norms (British Columbia Nutrition Survey; BCNS). Bivariate and regression analyses examined factors associated with NHP use. Assessment of potential adverse effects of NHP use was based on comparing nutrient intakes from food plus supplements with the Dietary Reference Intakes and by reviewing databases for reported adverse health effects. RESULTS Two-thirds (66%; 95% CI 56 to 75) were taking at least one NHP; 58% (95% CI 47 to 68) were taking NHPs in combination with psychiatric medications. The proportion of each type of NHP used was generally higher than the BCNS (range of p's < 0.05 to 0.0001). When intakes from food and NHP sources were combined, a small proportion exceeded any Lowest-Observed-Adverse-Effect-Levels: only for niacin (n = 17) and magnesium (n = 6), two nutrients for which the potential for adverse effects is minimal. Conversely, about 38% (95% CI 28 to 49) of the sample were taking a non-nutrient based NHP for which previous adverse events had been documented. CONCLUSIONS The prevalent use of NHPs in this population suggests that health care providers need to be knowledgeable about their characteristics. The efficacy and safety of NHPs in relation to mental health warrants further investigation.

Abstract
BACKGROUND Pregnant women were recruited into the Alberta Pregnancy Outcomes and Nutrition (APrON) study in two cities in Alberta, Calgary and Edmonton. In Calgary, a larger proportion of women obtain obstetrical care from family physicians than from obstetricians; otherwise the cities have similar characteristics. Despite similarities of the cities, the recruitment success was very different. The purpose of this paper is to describe recruitment strategies, determine which were most successful and discuss reasons for the different success rates between the two cities. METHODS Recruitment methods in both cities involved approaching pregnant women (< 27 weeks gestation) through the waiting rooms of physician offices, distributing posters and pamphlets, word of mouth, media, and the Internet. RESULTS Between May 2009 and November 2010, 1,200 participants were recruited, 86% (1,028/1,200) from Calgary and 14% (172/1,200) from Edmonton, two cities with similar demographics. The most effective strategy overall involved face-to-face recruitment through clinics in physician and ultrasound offices with access to a large volume of women in early pregnancy. This method was most economical when clinic staff received an honorarium to discuss the study with patients and forward contact information to the research team. CONCLUSION Recruiting a pregnancy cohort face-to-face through physician offices was the most effective method in both cities and a new critically important finding is that employing this method is only feasible in large volume maternity clinics. The proportion of family physicians providing antenatal and post-natal care may impact recruitment success and should be studied further.

Abstract
Epigenetics is revealing how "nature is nurtured", with environmental factors such as nutrition, environmental neurotoxicants, and psychological stress influencing DNA expression. In this current opinion paper, we argue that understanding the dynamic interplay between the genome acquired at conception and environmental exposures throughout life requires pregnancy and birth cohorts, and that greater Canadian national commitment to the infrastructure needed for sustaining such cohorts is warranted. We present a framework that is now being implemented in Alberta.

Abstract
BACKGROUND Postpartum depression is a serious problem for women and their offspring. Micronutrient supplements are recommended for pregnant women because of their documented protective effects for the offspring, but their potential beneficial effects on maternal mental health are unknown. This study investigated the association between prenatal micronutrient supplementation and the risk for symptoms of postpartum depression in a longitudinal pregnancy cohort from the Alberta Pregnancy Outcomes and Nutrition (APrON) study. METHODS Participants came from a cohort of the first 600 APrON women. Supplemental nutrient intake and symptoms of depression (measured with the Edinburgh Postnatal Depression Scale (EPDS)) were collected at each trimester and 12 weeks postpartum. RESULTS Of the 475 participants who completed the EPDS at least twice in pregnancy and at 12 weeks postpartum, 416 (88%) scored <10 and 59 (12%) scored ≥10, where an EPDS ≥10 is considered to be "at least probable minor depression". Mean nutrient intakes from supplements were higher in women with lower EPDS scores, particularly selenium (p = 0.0015) and omega-3s (p = 0.01). Bivariate analyses showed that several demographic and social/lifestyle variables were associated with EPDS ≥10: not having been born in Canada (p = 0.01), greater number of chronic conditions (p = 0.05), greater number of stressful life events during this pregnancy (p = 0.02), and lower prenatal and postnatal support (p = 0.0043 and p = 0.0001, respectively). Adjusting for covariates and nutrients known to be associated with postpartum depression, logistic regression showed that having a prenatal EPDS ≥ 10 increased the odds of postpartum depressive symptoms (second and third trimester OR = 3.29, 95% CI = 1.55 - 7.01, p = 0.004 and OR = 4.26, 95% CI = 2.05 - 8.85, p < 0.0001, respectively), while prenatal supplemental selenium (per 10 mcg, OR = 0.76, 95% CI = 0.74 - 0.78, p = 0.0019) and postnatal social support (OR = 0.87, 95% CI = 0.78 - 0.97, p = 0.0015) were protective. CONCLUSIONS Multiple factors, including supplementary selenium intake, are associated with the risk of postpartum depressive symptoms. Future research on dietary supplementation in pregnancy with special attention to selenium intake is warranted.

Abstract
Analysis of genetic linkage to dyslexia was performed using 133,165 array-based SNPs genotyped in 718 persons from 101 dyslexia-affected families. Results showed five linkage peaks with lod scores >2.3 (4q13.1, 7q36.1-q36.2, 7q36.3, 16p12.1, and 17q22). Of these five regions, three have been previously implicated in dyslexia (4q13.1, 16p12.1, and 17q22), three have been implicated in attention-deficit hyperactivity disorder (ADHD, which highly co-occurs with dyslexia; 4q13.1, 7q36.3, 16p12.1) and four have been implicated in autism (a condition characterized by language deficits; 7q36.1-q36.2, 7q36.3, 16p12.1, and 17q22). These results highlight the reproducibility of dyslexia linkage signals, even without formally significant lod scores, and suggest dyslexia predisposing genes with relatively major effects and locus heterogeneity. The largest lod score (2.80) occurred at 17q22 within the MSI2 gene, involved in neuronal stem cell lineage proliferation. Interestingly, the 4q13.1 linkage peak (lod 2.34) occurred immediately upstream of the LPHN3 gene, recently reported both linked and associated with ADHD. Separate analyses of larger pedigrees revealed lods >2.3 at 1-3 regions per family; one family showed strong linkage (lod 2.9) to a known dyslexia locus (18p11) not detected in our overall data, demonstrating the value of analyzing single large pedigrees. Association analysis identified no SNPs with genome-wide significance, although a borderline significant SNP (P = 6 × 10(-7)) occurred at 5q35.1 near FGF18, involved in laminar positioning of cortical neurons during development. We conclude that dyslexia genes with relatively major effects exist, are detectable by linkage analysis despite genetic heterogeneity, and show substantial overlapping predisposition with ADHD and autism.

Abstract
Pregnancy is thought to diminish a woman's appraisal of and affective response to stressors. To examine this assumption, we used an electronic diary and an ecological momentary assessment strategy to record women's (n = 85) experiences of positive and negative affect five times each day over 2 days within each trimester of pregnancy. The women also completed the Edinburgh Postnatal Depression Scale in each trimester. Multilevel modeling indicated nonlinear patterns for both positive and negative affect that differed by the level of depressive symptoms. The findings suggest that changes in the psychological experience over the course of pregnancy are dynamic and not progressively attenuated.

Abstract
Psychosis is difficult to treat effectively with conventional pharmaceuticals, many of which have adverse long-term health consequences. In contrast, there are promising reports from several research groups of micronutrient treatment (vitamins, minerals, amino acids and essential fatty acids) of mood, anxiety and psychosis symptoms using a complex formula that appears to be safe and tolerable. We review previous studies using this formula to treat mental symptoms, and present an 11-year-old boy with a 3-year history of mental illness whose parents chose to transition him from medication to micronutrients. Symptom severity was monitored in three clusters: anxiety, obsessive compulsive disorder and psychosis. Complete remission of psychosis occurred, and severity of anxiety and obsessional symptoms decreased significantly (p<0.001); the improvements are sustained at 4-year follow-up. A cost comparison revealed that micronutrient treatment was <1% of his inpatient mental healthcare. Additional research on broad-spectrum micronutrient treatment is warranted.

Abstract
The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration.

Abstract
OBJECTIVE The purpose of this study was to investigate the nutrient intakes of people with mood disorders. METHOD A cross-sectional survey using 3-day food records was carried out in 97 adults with bipolar or major depressive disorder to compare nutrient intakes with Dietary Reference Intakes and British Columbia Nutrition Survey (BCNS) data. Blood levels of selected nutrients were compared to reference ranges. Bivariate and multivariate analyses examined the effects of sociodemographic and clinical variables on nutrient intakes. RESULTS The average age of respondents was 46 (±13) years; most were women (n = 69) who had less than a university degree (n = 60) and whose incomes were in the government-defined lower range (n = 39). Compared with the BCNS, a larger proportion of the sample was below the estimated average requirement for thiamin (26% vs 8%), riboflavin (21% vs 4%), folate (64% vs 27%), phosphorous (12% vs 1%), and zinc (39% vs 15%; all P < 0.0001), as well as vitamin B(6) (25% vs 16%) and vitamin B(12) (27% vs 8%; both P < 0.05). Combined intakes of food and supplements helped reduce the prevalence of inadequacy; however, with supplementation, the proportion of participants exceeding the tolerable upper intake levels for niacin, vitamin B(6), folate, vitamin C, calcium, magnesium, iron, and zinc ranged from 1%-8%. Income, relationship status, age, gender, and caloric intake were associated with intakes of many nutrients. Types of medications were associated with nutrient intakes, as lower intakes of thiamin and phosphorous (P < 0.05) were found with antidepressant use, higher calcium and iron intakes (P < 0.05) were associated with antianxiety medication use, and magnesium intakes were increased with mood stabilizers (regression coefficient = 52.61, P < 0.05, 95% confidence interval = 0.74 to 104.48). CONCLUSIONS Adults with mood disorders are at risk for many nutrient inadequacies, as well as occasional excesses; social, demographic, and clinical factors may affect their nutrient intakes.

Abstract
BACKGROUND A growing body of literature links nutrition to mood, especially in epidemiological surveys, but there is little information characterizing food intake in people with diagnosed mood disorders. METHODS Food intake obtained from 3-day food records was evaluated in 97 adults with mood disorders, whose diagnoses were confirmed in structured interviews. Information from a population nutrition survey, national guidelines for nutritional intakes (Eating Well with Canada's Food Guide) and North American dietary guidelines (Dietary Reference Intakes) was utilized to evaluate the quality of their food intake. RESULTS Compared to the regional nutrition survey data and national guidelines, a greater proportion of study participants consumed fewer of the recommended servings of grains (p < 0.001) and vegetables and fruits (p < 0.05), and less than the lower boundary of the Adequate Macronutrient Distribution Range (AMDR) for α-linolenic acid (p < 0.001). The study sample also had greater intakes of high-fat whole grain products (p < 0.01), processed meats (p < 0.00001), and higher sugar, fat or salty foods (p < 0.00001). Of the 1746 total meals and snacks consumed, 39% were from sources outside the home, suggesting a lack of time devoted to meal preparation. Finally, a subsample of 48 participants agreed to have blood tests: 44% had mild hypercholesterolemia (> 5.2 and ≤ 6.2 mmol/L) and 21% had hypercholesterolemia (> 6.2 mmol/L). CONCLUSIONS Much research has proposed multiple ways in which healthier diets may exert protective effects on mental health. The results of this study suggest that adults with mood disorders could benefit from nutritional interventions to improve diet quality.

Abstract
OBJECTIVE To evaluate the relation between nutrient intake and psychiatric functioning in adults with confirmed mood disorders. METHOD A cross-sectional study was conducted of the intake of major (that is, carbohydrates, fat, and protein) and minor (that is, vitamins and minerals) nutrients (from 3-day food records and a Food Frequency Questionnaire), Global Assessment of Functioning (GAF) scores, and symptoms of depression and mania (the Hamilton Depression Rating Scale and the Young Mania Rating Scale) in 97 community-based adults with mood disorders whose diagnoses were confirmed with structured interviews. RESULTS Significant correlations were found between GAF scores and energy (kilocalories), carbohydrates, fibre, total fat, linoleic acid, riboflavin, niacin, folate, vitamin B6, vitamin B12, pantothenic acid, calcium, phosphorus, potassium, and iron (all P values < 0.05), as well as magnesium (r = 0.41, P < 0.001) and zinc (r = 0.35, P < 0.001). Though modest in magnitude, the pattern of correlations was consistent, indicating higher levels of mental function associated with a higher intake of nutrients. Depression and mania scores, which were generally mild or moderate, did not individually show consistent patterns. When dietary supplement use was added to nutrient intakes from food, GAF scores remained positively correlated (P < 0.05) with all dietary minerals. CONCLUSION This detailed analysis in a clinically diagnosed sample was consistent with prior epidemiologic surveys, revealing an association between higher levels of nutrient intakes and better mental health. Nutrient intakes warrant further consideration in the treatment of people with mood disorders.

Abstract
The Attention Network Test (ANT) was used to examine alerting, orienting, and executive control in fetal alcohol spectrum disorder (FASD) versus attention deficit hyperactivity disorder (ADHD). Participants were 113 children aged 7 to 10 years (31 ADHD-Combined, 16 ADHD-Primarily Inattentive, 28 FASD, 38 controls). Incongruent flanker trials triggered slower responses in both the ADHD-Combined and the FASD groups. Abnormal conflict scores in these same two groups provided additional evidence for the presence of executive function deficits. The ADHD-Primarily Inattentive group was indistinguishable from the controls on all three ANT indices, which highlights the possibility that this group constitutes a pathologically distinct entity.

Abstract
Background Both scientists and the public routinely refer to randomized controlled trials (RCTs) as being the 'gold standard' of scientific evidence. Although there is no question that placebo-controlled RCTs play a significant role in the evaluation of new pharmaceutical treatments, especially when it is important to rule out placebo effects, they have many inherent limitations which constrain their ability to inform medical decision making. The purpose of this paper is to raise questions about over-reliance on RCTs and to point out an additional perspective for evaluating healthcare evidence, as embodied in the Hill criteria. The arguments presented here are generally relevant to all areas of health care, though mental health applications provide the primary context for this essay. Discussion This article first traces the history of RCTs, and then evaluates five of their major limitations: they often lack external validity, they have the potential for increasing health risk in the general population, they are no less likely to overestimate treatment effects than many other methods, they make a relatively weak contribution to clinical practice, and they are excessively expensive (leading to several additional vulnerabilities in the quality of evidence produced). Next, the nine Hill criteria are presented and discussed as a richer approach to the evaluation of health care treatments. Reliance on these multi-faceted criteria requires more analytical thinking than simply examining RCT data, but will also enhance confidence in the evaluation of novel treatments. Summary Excessive reliance on RCTs tends to stifle funding of other types of research, and publication of other forms of evidence. We call upon our research and clinical colleagues to consider additional methods of evaluating data, such as the Hill criteria. Over-reliance on RCTs is similar to resting all of health care evidence on a one-legged stool.

Abstract
BACKGROUND Theoretically, consumption of complex, multinutrient formulations of vitamins and minerals should be safe, as most preparations contain primarily the nutrients that have been in the human diet for millennia, and at safe levels as defined by the Dietary Reference Intakes. However, the safety profile of commercial formulae may differ from foods because of the amounts and combinations of nutrients they contain. As these complex formulae are being studied and used clinically with increasing frequency, there is a need for direct evaluation of safety and tolerability. METHODS All known safety and tolerability data collected on one complex nutrient formula was compiled and evaluated. RESULTS Data were assembled from all the known published and unpublished studies for the complex formula with the largest amount of published research in mental health. Biological safety data from 144 children and adults were available from six sources: there were no occurrences of clinically meaningful negative outcomes/effects or abnormal blood tests that could be attributed to toxicity. Adverse event (AE) information from 157 children and adults was available from six studies employing the current version of this formula, and only minor, transitory reports of headache and nausea emerged. Only one of the studies permitted a direct comparison between micronutrient treatment and medication: none of the 88 pediatric and adult participants had any clinically meaningful abnormal laboratory values, but tolerability data in the group treated with micronutrients revealed significantly fewer AEs and less weight gain. CONCLUSIONS This compilation of safety and tolerability data is reassuring with respect to the broad spectrum approach that employs complex nutrient formulae as a primary treatment.

Abstract
BACKGROUND Although maternal nutrient status influences all aspects of fetal development including the brain, the impact of micronutrient supplementation on the baby's mental function is a topic of debate. This systematic review assesses the effect of single and multiple micronutrient supplementation during pregnancy on offspring mental development. METHODS Eleven electronic literature databases were searched using key terms of various combinations and filter string terms. Reference lists of articles selected for review were scanned for citations fitting the same inclusion criteria. Each stage of the literature retrieval and review process was conducted independently by two reviewers. The CONSORT checklist was used to assess study quality. RESULTS A total of 1316 articles were retrieved from the electronic database search, of which 18 met the inclusion criteria and were evaluated. The selected studies were randomized controlled trials published from 1983 to 2010, with high variance in sample size, intervention type, and outcome measures. The median CONSORT score was 15 (range 12 - 19). Due to inconsistent interventions and outcome measures among the studies, no conclusive evidence was found that enhancing the intrauterine environment through micronutrient supplementation was associated with child mental development in a number of dimensions. There was some evidence to support n-3 fatty acids or multi-micronutrients having some positive effect on mental development, but the evidence for single nutrients was much weaker. CONCLUSIONS The study of children's mental outcomes as a function of prenatal supplementation is still relatively new, but the results of this systematic review suggest that further work with multiple micronutrients and/or n-3 fatty acids should be conducted.

Abstract
Autism spectrum disorder (ASD) is often accompanied by self-injurious behavior (SIB), aggression, and tantrums, symptoms that have reportedly improved with micronutrient (vitamins and minerals) treatment. The current study took advantage of naturally occurring differences in parental preferences for treatment approaches. The micronutrient group asked for treatment without pharmaceuticals (n = 44, aged 2-28 years at entry [M = 8.39 +/- 5.58]). Their records were matched with those of 44 similar children whose families requested conventional treatment (medication group). Both groups improved on both the Childhood Autism Rating Scale and the Childhood Psychiatric Rating Scale (all p values <0.0001). Both groups also exhibited significant decreases in total Aberrant Behavior Checklist scores, but the micronutrient group's improvement was significantly greater (p < 0.0001). SIB Intensity was lower in the micronutrient group at the end of the study (p = 0.005), and improvement on the Clinical Global Impressions scale was greater for the micronutrient group (p = 0.0029). It is difficult to determine whether the observed changes were exerted through improvement in mood disorder or through an independent effect on autistic disorder. There were some advantages to treatment with micronutrients-lower activity level, less social withdrawal, less anger, better spontaneity with the examiner, less irritability, lower intensity SIB, markedly fewer adverse events, and less weight gain. Advantages of medication management were insurance coverage, fewer pills, and less frequent dosing.

Abstract
AIM The attention and inhibition problems found in children with attention-deficit-hyperactivity disorder (ADHD) are also common in children with fetal alcohol spectrum disorders (FASDs). Attempts to distinguish ADHD from FASDs in terms of these deficits are rare and were pursued in this study. METHOD A total of 116 children (47 with ADHD, 31 males, 16 females; 30 with FASDs, 17 males, 13 females; and 39 comparison children, 20 males, 19 females) participated. The mean age was 9 years 4 months (SD 1y 8mo) in the ADHD groups, 8 years 10 months (SD 1y 2mo) in the FASD group, and 9 years 1 month (SD 1y 1mo) in the comparison group. Sustained attention was tested with a slow event rate continuous performance task (CPT). Inhibitory control was tested with both a slow and fast event rate Go/No-Go task. RESULTS On the CPT task, children with ADHD, combined type (ADHD-C), ADHD, primarily inattentive type (ADHD-PI), and FASDs showed greater declines in task performance as a function of time than comparison children, suggesting sustained attention problems in all clinical groups. Children's Go/No-Go performance was event-rate dependent, with the ADHD-C group being affected in the slow condition and the ADHD-PI and FASD groups having problems with the fast condition. INTERPRETATION Children with ADHD-C are typically impaired in handling understimulation, while children with FASDs may have problems with overstimulation. The dissociation in responsivity to event rate between groups may have significant differential diagnostic value.

Abstract
There is an ongoing debate regarding the diagnostic overlap between Attention Deficit Hyperactivity Disorder (ADHD) and Fetal Alcohol Spectrum Disorder (FASD). Differential diagnosis is important because of treatment implications. Children aged 7-10years (47 ADHD, 30 FASD, 39 controls) participated. The Movement Assessment Battery for Children (M-ABC) and the Clinical Observations of Motor and Postural Skills (COMPS) were used. Force plate and electromyography data were collected during static balance and balance perturbation. On the M-ABC both children with ADHD and FASD had more motor problems than controls. The ADHD-Combined and the ADHD-Predominantly Inattentive subgroups were similarly affected in their fine motor skills. On the COMPS, the majority of children in both groups performed in the normal range, but for those children clinically affected, it was the children with ADHD who were more likely to be severely impaired. The children with ADHD were characterized by early onset latencies of the tibialis anterior muscles and increased amplitudes of the gastrocnemius muscles. Difficulty scaling muscle force reflecting medial cerebellar involvement may be the key problem in ADHD. Cerebellar involvement in the postural instability in FASD awaits further study.
