Abstract
The study was conducted to analyze the contribution of home garden vegetables in reducing stunting among 6- to 23-month-old children from South Tigray, Northern Ethiopia. The quasi-experimental study design was used. Multistage sampling technique was used to select the districts and study communities. A total of 94 purposively selected vegetable producer (intervention) households and 260 randomly selected non-producer (control) households were included in the study (1:3 ratio). The recumbent length of children was measured using horizontal wooden board to the nearest 0.1 cm. The length-for-age Z-scores were computed using WHO-Anthro 2006 software. Propensity score-matching and difference-in-difference (DID) estimates were used to analyze data using STATA software version 12. Prevalence of child stunting was 19.8 (12.7-29.4) and 21.1 (16.4-26.7)% (baseline) and 43.5 (33.5-54.1) and 46.5 (45.7-47.2)% (end line) among intervention and control groups, respectively. Child stunting was higher for boys and older children from both intervention and control households. DID estimation revealed that there was no significant difference in child stunting between intervention and control households (DID = 1.7, p = .604). However, there was an intervention effect of -0.5, 2.5, and 1.7% in the prevalence of child stunting among females, males, and both sexes, respectively. Vegetable production as an intervention strategy reduced the prevalence of stunting in children aged 6-23 months. However, vegetable production needs to be well integrated with other nutrition-sensitive interventions to realize the objective of reducing child stunting.

Abstract
BACKGROUND Limited studies in Ethiopia showed that infants and young children are at high risk of inadequate intake of energy and nutrients. However, inclusive assessment of both nutrient intakes and their food sources are lacking. We aimed at assessing energy and nutrient intakes and their food sources during religious fasting and non-fasting periods among 6-23 months old children in Northern Ethiopia. METHODS Data for this longitudinal study were collected following repeated multiple-pass 24-h dietary recall technique through face-to-face interviews with primary caregivers. Using a two-stage systematic random sampling method, a total of 570 and 551 children participated respectively in the lent fasting and non-fasting periods. Energy and nutrient intakes were estimated and compared with WHO daily requirements. All foods that a child consumed on the day preceding the date of data collection were recorded and processed with database software. Chi-square and t- tests were used to analyze the data. Non-normally distributed data were analyzed using Wilcoxon signed-rank test and statistical significance was set at p < 0.05. RESULTS The overall prevalence of child stunting was 41.4%. Almost all of children (99.6%) consumed grains, roots, and tubers. The inadequacy prevalence of energy, protein and eight selected micronutrients (calcium, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C) intake were 96.2, 44.9, and 95.5%, respectively. Calcium and zinc were the highest (100%) deficits observed across all age groups. Although consumption of animal source foods (ASFs) was very low (dairy 10.1%, meat 2.3% and eggs 23.6%), there was significantly higher consumption of meat and eggs during the non-fasting compared to fasting period (p < 0.001). CONCLUSIONS Inadequate intake of energy and nutrients was common among 6-23 months old children. Cereals were found to be the main sources of many of the nutrients. The consumption of ASFs among 6-23-month-old children was low which was also affected by the religious fasting period. Hence, strengthening social and behavior change communication, supporting rural households to raise poultry and small ruminants is recommended.

Abstract
Background The SINgapore GERiatric intervention study to reduce cognitive decline and physical frailty (SINGER) randomised controlled trial (RCT) uses a multidomain lifestyle interventions approach, shown to be effective by the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) trial, to delay cognitive decline. Objective To investigate the efficacy and safety of the SINGER multidomain lifestyle interventions in older adults at risk for dementia to delay cognitive decline. Participants 1200 participants between 60–77 years old, with Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) dementia risk score ≥6, fulfilling at least one of the following LIBRA index for diet, cognitive activity, physical activity and a Montreal Cognitive Assessment (MoCA) score ≥18, ≤27 points, will be recruited across Singapore. Methods SINGER is a 2-year multi-site RCT consisting of multidomain interventions: dietary advice, exercise, cognitive training, and vascular risk factors management. Participants will be randomised into either the Self-Guided Intervention (SGI; general lifestyle and health information and resources) or Structured Lifestyle Intervention (SLI) group. The SLI comprises diet training (6 group and 3 individual sessions over 12 months); exercise (supervised: 1-hour twice weekly for 6 months, unsupervised: 2–3/week for the rest of the study duration); cognitive sessions (15–30 minutes/session, 3/week for 6 months, together with 10 workshops in 24 months). Vascular management takes place every 3–6 months or otherwise as specified by study physicians. The primary outcome is global cognition measured using the modified Neuropsychological Battery assessing performance in various domains, such as episodic memory, executive function and processing speed. Secondary outcome measures include: domain-specific cognition and function, imaging evidence of brain and retinal changes, incidence and progression of chronic diseases, blood biomarkers, quality of life, mental health and cost-benefit analysis. Conclusions SINGER is part of the Worldwide-FINGERS international network, which is at the forefront of harmonizing approaches to effective non-pharmacological interventions in delaying cognitive decline in older adults at risk of dementia. By establishing the efficacy of multidomain interventions in preventing cognitive decline, SINGER aims to implement the findings into public health and clinical practices by informing policy makers, and guiding the design of community- and individual-level health promotion initiatives.

Abstract
BACKGROUND Despite progress made to improve access to child health services, mothers' consistent utilization of these services has been constrained by several factors. This study is aimed at assessing the inequalities in key child health service utilization and assess the role of antenatal care (ANC) on subsequent service use. METHOD The analysis of the present study was based on the Ethiopian Demographic and Health Surveys, a nationally representative sample of 10,641 children. A health service utilization score was constructed from the affirmative responses of six key child health interventions associated with the most recent birth: ANC service, delivery of the last child at health facilities, postnatal care services, vitamin A intake, iron supplementation and intake of deworming pills by the index child. A mixed effect Poisson regression model was used to examine the predictors of health service utilization and three separate mixed effect logistic regression models for assessing the role of ANC for continued use of delivery and postnatal care services. RESULTS The results of mixed effect Poisson regression indicate that the expected mean score of health service utilization was lower among non-first birth order children, older and high parity women, those living in polygamous families and women living in households with no access to radio. The score was higher for respondents with better education, women who had previous experience of terminated pregnancy, residing in more affluent households, and women with experiences of mild to high intimate partner violence. Further analysis of the three key health services (ANC, delivery, and postnatal care), using three models of mixed effect logistic regression, indicates consistent positive impacts of ANC on the continuum of utilizing delivery and postnatal care services. ANC had the strongest effects on both institutional delivery and postnatal care service utilization. CONCLUSION The findings implicated that maternal and child health services appear as continuum actions/behavior where utilization of one affects the likelihood of the next service types. The study indicated that promoting proper ANC services is very beneficial in increasing the likelihood of mothers utilizing subsequent services such as delivery and postnatal care services.

Abstract
BACKGROUND The beginning of the COVID-19 pandemic presented many sudden challenges regarding food, including grocery shopping changes (eg, reduced store hours, capacity restrictions, and empty store shelves due to food hoarding), restaurant closures, the need to cook more at home, and closures of food access programs. Eat Well Saskatchewan (EWS) implemented a 16-week social media campaign, #eatwellcovid19, led by a dietitian and nutrition student that focused on sharing stories submitted by the Saskatchewan public about how they were eating healthy during the COVID-19 pandemic. OBJECTIVE The goal of this study was to describe the implementation of the #eatwellcovid19 social media campaign and the results from the evaluation of the campaign, which included campaign performance using social media metrics and experiences and perspectives of campaign followers. METHODS Residents of Saskatchewan, Canada, were invited to submit personal stories and experiences to EWS about how they were eating healthy during the COVID-19 pandemic from April to August 2020. Each week, one to three stories were featured on EWS social media platforms-Facebook, Instagram, and Twitter-along with evidence-based nutrition information to help residents become more resilient to challenges related to food and nutrition experienced during the COVID-19 pandemic. Individuals who submitted stories were entered into a weekly draw for a Can $100 grocery gift card. Social media metrics and semistructured qualitative interviews of campaign followers were used to evaluate the #eatwellcovid19 campaign. RESULTS In total, 75 stories were submitted by 74 individuals on a variety of topics (eg, grocery shopping, traditional skills, and gardening), and 42 stories were featured on social media. EWS shared 194 #eatwellcovid19 posts across social media platforms (Facebook: n=100; Instagram: n=55; and Twitter: n=39). On Facebook, #eatawellcovid19 reached 100,571 followers and left 128,818 impressions, resulting in 9575 engagements. On Instagram, the campaign reached 11,310 followers, made 14,145 impressions, and received 823 likes and 15 comments. On Twitter, #eatwellcovid19 made 15,199 impressions and received 424 engagements. Featured story submission posts had the best engagement on Facebook and the most likes and comments on Instagram. The EWS social media pages reported increases in their following during the campaign (Instagram: +30%; Facebook: +14%; and Twitter: +12%). Results from the interviews revealed that there were two types of campaign followers: those who appreciated hearing the stories submitted by followers, as it helped them to feel connected to the community during social isolation, and those who appreciated the evidence-based information. CONCLUSIONS Numerous stories were submitted to the #eatwellcovid19 social media campaign on various topics. On Instagram and Facebook, posts that featured these stories had the highest engagement. During this campaign, EWS's social media following increased by more than 10% on each platform. The approach used for the #eatwellcovid19 campaign could be considered by others looking to develop health promotion campaigns.

Abstract
BACKGROUND Childhood morbidities such as diarrhea and pneumonia are the leading causes of death in Ethiopia. Appropriate healthcare-seeking behavior of mothers for common childhood illnesses could prevent a significant number of these early deaths; however, little nation-wide research has been conducted in Ethiopia to assess mothers' healthcare-seeking behavior for their under five children. METHODS The study used the Ethiopian Demographic and Health Surveys (EDHS) data. The EDHS is a cross sectional survey conducted in 2016 on a nationally representative sample of 10,641 respondents. The main determinants of care-seeking during diarrhea and acute respiratory infection (ARI) episodes were assessed using multiple logistic regression analyses while adjusting for complex survey design. RESULTS Only 43% and 35% of households sought medical attention for their children in episodes of diarrhea and ARI, respectively, during a reference period of 2 weeks before the survey. The odds of seeking care for diarrhea are lower for non-working mothers versus working mothers. The likelihood of seeking care for diarrhea or ARI is higher for literate fathers compared to those with no education. The place of delivery for the child, receiving postnatal checkup and getting at least one immunization in the past determined the likelihood of seeking care for ARI, but not for diarrhea. The odds of seeking care are higher for both diarrhea and ARI among households that are headed by females and where mothers experienced Intimate Partner Violence (IPV) violence. Religion and types of family structure are also significant factors of seeking care for diarrhea episodes, but not for ARI. CONCLUSIONS The findings call for more coordinated efforts to ensure equitable access to health care services focusing on mothers living in deprived household environment. Strengthening partnerships with public facilities, private health care practitioners, and community-based organizations in rural areas would help further improve access to the services.

Abstract
BACKGROUND Undernutrition among children is a priority area of public health concern in Ethiopia. The purpose of this study was to examine disparities in Infant and Young Child Feeding (IYCF) practices among children 6-23 months. METHOD Data were drawn from the 2016 Ethiopian Demographic and Health Surveys (EDHS). A total of 3240 children aged 6-23 months were used for the present analysis. The outcome variable was IYCF practice score (ranging 0-7) which was constructed based on the linear and combined effects of four sets of variables: breastfeeding, avoidance of bottle feeding, diet diversity score and minimum feeding frequency. IYCF practice score was further recoded into three categories. Proportional odds regression was used to assess the determinants of IYCF category. RESULTS The proportional odds regression analysis showed that IYCF scores significantly decreased by 5% (Adjusted Odds Ratio (AOR) = 0.95; 95% CI: 0.93-0.97) for every unit increase in the child's age. Households with fathers of primary and secondary and above level education were 1.37 times (95% CI: 1.14-1.66) and 1.67 times (95% CI: 1.26-2.23) more likely to be in the high IYCF category than in the poor IYCF category. The likelihood of being in the high IYCF practice category decreased for non-working mothers by 30% (AOR = 0.70; 95% CI: 0.59-0.83) compared to those working in gainful employment. The chance of being in the high IYCF practice category decreased by 29% for households with no access to radio (AOR = 0.71; 95% CI: 0.59-0.85). Those with medium and rich/richer wealth category were 1.54 times (95% CI: 1.22-1.94) and 1.40 times (95% CI: 1.11-1.75) more likely to belong to high IYCF practice category than being in poor IYCF category. For every unit increase in health service utilization, the chance of falling in higher IYCF category increases by 1.15 times (95% CI: 1.08-1.23). The chance of falling in higher IYCF practice category decreases for rural residents by 37% (AOR = 0.63; 95% CI: 0.47-0.84) compared to those residing in urban areas. CONCLUSION For a child, the first two years is the time span during which linear faltering of growth is most prevalent and the period when the process of becoming stunted is almost complete. This study recommends improving access to women for gainful employment, provision of economic support to poor rural women, education and promotion of nutrition messages using most accessible media and boosting the positive role of fathers in child feeding practices.

This paper presents the results of a retrospective case-controlled cohort study to investigate the effectiveness of a donor-site local anaesthetic infusion protocol to reduce opioid requirements, length of intensive therapy unit (ITU) stay, and incidence of postoperative delirium. Adult free flap head and neck patients were identified from a prospective database (n = 86). There was a significant reduction in mean opioid requirements (p < 0.001). Postoperative delirium was observed in 12 of 35 patients before introduction of the protocol, and in 10 of 51 patients after its introduction (p = 0.139). Donor-site local anaesthetic infusion reduces opioid requirements for patients undergoing head and neck free flap reconstruction, and is a valuable adjunct to an enhanced recovery protocol.

Abstract
BACKGROUND In Ethiopia, child undernutrition and anemia are major public health concerns, resulting in increased childhood morbidity and mortality. Despite progress made to reduce the prevalence of malnutrition (especially stunting) from 50% in 2000 to 38% in 2016, little is known about the magnitude and risk factors for concurrent nutritional deficiencies in Ethiopia. METHODS Analysis for this study was based on a total sample of 9218 children aged 6-59 months drawn from the Ethiopian Demographic and Health Survey (EDHS) conducted in the year 2016. The study used two outcome variables: Multiple nutrition deficit index formed by combining stunting, underweight, wasting and anemia status; and a concurrent stunting and anemia (CAS) index. Two mixed effect regression models, Poisson and Logistic, were used to identify the key risk factors of the two outcome variables, respectively. RESULTS The proportion of children with stunting (length-for-age), underweight (weight-for-age) and wasting children (weight-for-length) was 38%, 25.2% and 9.4%, respectively. About 58% of the children had anemia. The prevalence of children with concurrent stunting and anemia children was 24.8%. Our results showed that the risks of multiple nutritional problems were determined by a range of individual, household and behavioral factors including: sex of the child, age of the child, birth order, parity, parental education, religion, household wealth index and type of family structure. The proximate variables (hygiene and sanitation score, feeding practice, and child health service utilization score) were also found to exert a strong influence on the risk of multiple nutritional deficiencies. The likelihood of co-occurrence of stunting and anemia was determined by certain individual and household factors, including sex of the child, age of the child, maternal education, household asset based wealth, religion and household hygiene and sanitation. CONCLUSIONS This study underscores the importance of improving parental education, household wealth, hygiene and sanitation conditions, promoting feeding practice and child health service utilization. Also, any nutrition sensitive and specific intervention should consider a child's characteristics such as his/her age, gender and birth order.

Abstract
Background Improving children’s weight status through nutrition education (NE) for mothers about using pulses in complementary feeding has been demonstrated in pilot studies, but no effect on stunting was reported. The aim of the study was to assess the impact of a 9-month pulse-nutrition education program on improving mothers’ knowledge, attitude, and practices (KAP) towards pulses, as well as its effect on children’s diet diversity, and nutritional status. The NE was delivered by Health Extension Workers (HEWs). Methods A cluster randomized study was employed for the community-based interventional study. Twelve randomly selected villages in Sidama Zone, Southern Ethiopia were included in the study. A total of 772 mother-child pairs involved in the study; where 386 mother-child pairs in the intervention group received additional messages about pulse-cereal complementary food, and 386 pairs (the control) received only routine health education for 9 months. A survey on mothers’ KAP and anthropometric measurements of the children were taken at baseline, midpoint, and end point. ANOVA and descriptive statistics were used to analyzed data. Results At baseline and end point, maternal KAP and the dietary diversity score of the children (mean age at end point 18.8 ± 2.9 mo) were assessed. Intervention mothers’ KAP improved (p < 0.001) at midpoint and end point compared to that of the control group, as did frequency of pulse consumption and Dietary Diversity Score (DDS) among children. At 9 months, the prevalence of stunting, wasting, and underweight was significantly reduced in the intervention group compared to the control group (p = 0.001). Conclusions NE delivered by HEWs improved KAP of mothers regarding pulse consumption and dietary diversity of children led to improved nutritional status of the children. Training HEWs on the use of pulses for complementary food may be an effective way to improve the health of children in Ethiopian communities. Trial registration Clinicaltrials.gov #NCT02638571.

Abstract
In contrast to other pulses, chickpea has a relatively high fat content (3%-10%). This study was designed to investigate direct-expanded chickpea-sorghum extruded snacks (50:50, 60:40, and 70:30 chickpea:sorghum, w/w) with respect to: their oxidative stability and sensory properties during accelerated (55°C) and room temperature (25°C) storage; correlations between chemical markers (peroxide value and p-anisidine value) and sensory data during accelerated storage; and the shelf-life of snacks extruded at the optimal expansion point as determined by a rotatable central composite design. Peroxide values and p-anisidine values were in the range of 0-2.5 mEq/Kg and 5-30, respectively, for both accelerated and room temperature storage, and increased during storage (p < .05). 70:30 and 60:40 (w/w) chickpea-sorghum snacks had higher peroxide and p-anisidine values compared to the 50:50 snack during storage at either temperature (p < .05). Rancid aroma and off-flavor of 60:40 and 70:30 chickpea-sorghum snacks (slightly intense = 6) also were higher than that of the 50:50 snack (moderately weak = 3) (p < .05). Significant correlations (p < .05) were found between chemical markers and sensory attributes (p < .05). The study illustrated that shelf-life decreased as the percentage of chickpea in the blend increased. Therefore, in terms of shelf-life, a 50:50 chickpea-sorghum blend is preferable.

Abstract
To assess BAT activity in humans at a population level, infrared thermography (IRT) represents a safe, readily repeatable and affordable alternative to 18F-FDG-PET. Building upon a previously proposed method by our laboratory, we further refined the image computational algorithm to quantify BAT activation in the cervical-supraclavicular (C-SCV) region of healthy young men under thermo-neutral and cold exposure conditions. Additionally, we validated the whole-body calorimeter (WBC) in reliably measuring cold-induced thermogenesis. The temperature gradient between C-SCV-deltoid regions, and the corresponding difference in heat power output, increased upon cold air exposure relative to thermo-neutral conditions (by 74.88 %, p<0.0001; and by 71.34 %, p<0.0001 respectively). Resting and cumulative energy expenditure (EE) rose significantly (by 13.14 % and 9.12 % respectively, p=0.0001) while positive correlations between IRT measures and EE were found with cold air exposure (percentage change in heat power gradient between ROI and deltoid, cold air: r(2)=0.29, p=0.026, Pearson's correlation). IRT and WBC can be used to study BAT activation. The refined algorithm allows for more automation and objectivity in IRT data analysis, especially under cold air exposures.

Abstract
Context Metabolic inflexibility is a characteristic of insulin resistance, limiting the ability to transiently regulate oxidative metabolism and gene expression in response to nutrient availability. Little is known of the flexibility of post-transcriptional regulation, including circulatory miRNAs (c-miRNAs). Design The abundances of targeted c-miRNAs, with reported functions in metabolic regulation, were analysed in response to a high-carbohydrate meal in healthy weight insulin-sensitive (IS) and overweight insulin-resistant (IR) women. Participants Age-matched healthy weight IS (n = 20, BMI = 24.3 ± 0.70) and overweight IR (n = 20, BMI = 28.6 ± 0.67) women. Methods An abundance of c-miRNAs was quantified prior to and following a high-carbohydrate breakfast meal (2500 kJ; 50% carbohydrate, 20% fat and 27% protein). Target genes of the differentially regulated c-miRNA were measured in RNA extracted from circulatory peripheral blood mononuclear cells (PBMCs). Results In healthy weight IS women, both miR-15a-5p (p = 0.03) and miR-17-5p (p < 0.01) levels were halved at 4 h post-meal. These miRNA remained unaltered following the same meal in the overweight IR women. Furthermore, amongst genes targeted by these miRNA, CPT1A (p = 0.01) and IL8 (p = 0.03) had also reduced expression 4 h post-meal only in the healthy weight IS women. Conclusions The study findings provide preliminary evidence for a possible extension of metabolic inflexibility to include c-miRNAs.

Abstract
BACKGROUND Animal source foods provide high-quality protein and essential micronutrients within the human diet and are of particular significance for the health and development of children. Despite the availability of domestic livestock in rural households of Ethiopia, the diets of children are often monotonous and mainly cereal-based with low energy and nutrient density. OBJECTIVE Explore barriers and facilitators for the consumption of animal source foods among 6-23 months old children from the rural communities of Northern Ethiopia. METHODS A community-based exploratory qualitative study design was conducted in July through September 2018. A total of eight focus group discussions (56 individuals) and twenty-four qualitative interviews were conducted with mothers who are lactating, fathers, health extension workers, nutrition, and agriculture experts. Purposive sampling technique was used to include study participants based on their potential relevance in delivering a wealth of information. Thematic analysis strategies, a method for identifying, analyzing, and reporting themes within data, were used to code and grouped into related families and synthesize the qualitative data. RESULTS Consumption of animal source foods among 6-23 months old children was very low and the home-reared livestock and their products were mainly used for market purposes. Animal products are consumed during special societal occasions since they are considered as luxury food rather than an essential part of daily children's diet. Lack of nutrition knowledge, high cost of animal source foods, mothers' workload to herd livestock, low household income, low milk production, the poor linkage between health and agriculture sectors, and social norms and beliefs were identified as common barriers. While the presence of nutrition experts, cooking demonstrations, in-kind credit programs, livestock ownership, and government-led stunting reduction programs were the facilitators for the consumption of animal source foods in the study communities. CONCLUSIONS Reduced consumption of animal source foods inadvertently impacted dietary diversity of 6-23 months old children from the study communities. Thus, strengthening social and behavior change communication to promote the consumption of animal source foods, creating opportunities for women to own small livestock for household consumption and provide nutrition education on dietary restriction of animal source foods during religious periods among 6-23 months old children in the rural communities of Northern Ethiopia are recommended.

Abstract
Anticipating, identifying, and prioritizing strategic needs represent essential activities by research organizations. Decided benefits emerge when these pursuits engage globally important environment and health goals, including the United Nations Sustainable Development Goals. To this end, horizon scanning efforts can facilitate identification of specific research needs to address grand challenges. We report and discuss 40 priority research questions following engagement of scientists and engineers in North America. These timely questions identify the importance of stimulating innovation and developing new methods, tools, and concepts in environmental chemistry and toxicology to improve assessment and management of chemical contaminants and other diverse environmental stressors. Grand challenges to achieving sustainable management of the environment are becoming increasingly complex and structured by global megatrends, which collectively challenge existing sustainable environmental quality efforts. Transdisciplinary, systems-based approaches will be required to define and avoid adverse biological effects across temporal and spatial gradients. Similarly, coordinated research activities among organizations within and among countries are necessary to address the priority research needs reported here. Acquiring answers to these 40 research questions will not be trivial, but doing so promises to advance sustainable environmental quality in the 21st century.

Abstract
This study aimed to determine the effect of a 6-month in-school nutrition education intervention to improve pulse consumption on weight status of adolescent girls in Ethiopia. At the intervention school, 66 girls received bi-monthly lessons that included recipes and tastings. Girls (n = 66) at the control school had usual in-school activities. With pulse-based nutrition education which included discussions and demonstrations, knowledge, attitude and practice scores improved (p < 0.001) in the intervention group while control scores remained low and unchanged. Prevalence of underweight, measured as Body Mass Index (BMI) for age, decreased with the education intervention, from 13.6% to 3% (p = 0.004), while there was no significant change seen in control girls. In Ethiopia, equipping girls in schools with the knowledge and skills to improve food intake by consuming locally grown pulses may mitigate underweight in Ethiopian female adolescents.

Abstract
Addressing maternal and child undernutrition is a priority for the National Nutrition Program of Ethiopia. In a cross-sectional design, we selected mother-child pairs (n = 630) from Halaba, south Ethiopia (n = 413, two communities) and Zeway, Oromiya region (n = 217, one community). These communities were previously included in a project to improve agricultural practices. We aimed to estimate the level of maternal and child undernutrition in the two study sites and compare findings to regional/national reports. We also examined associations with gender, household-structure and nutrition/health related variables. Households were selected using simple random sampling based on list of households obtained from local health posts. Mothers were interviewed via questionnaire. Anthropometric measurements were taken from mothers-child pairs. Maternal undernutrition (% BMI<18.5) ranged from moderate (14% Zeway) to high (22% Halaba). In the children, stunting and underweight were very high (54% and 42% stunting, 36% and 21% underweight, in Halaba and Zeway, respectively). Up to 95% of Halaba and 85% of Zeway mothers reported “same as usual” or “less than usual” consumption patterns during their most recent pregnancy compared to periods of non-pregnancy. Mothers reported (61% in Halaba, 18% in Zeway) abstaining from consumption of certain nutritious foods for cultural reasons. Gender and socio-economic-demographic structure of the households, including imbalance of power, control of farm produce, physiological density, household size and dietary habits during pregnancy showed significant associations with maternal and child undernutrition (p<0.05). The levels of child and maternal undernutrition, particularly in children, were unexpected and of concern, given that a national nutrition program has been in place since 2008. The study provides insights for policy makers to improve women’s education, reproductive health services for better family planning, and strengthen nutrition/health programs designed to target vulnerable segments of the population in these and other rural communities and districts with similar structure and demographics in Ethiopia.

Abstract
Panelists in Saskatoon, Canada (n = 45) and Dhaka, Bangladesh (n = 98) participated in sensory evaluations of the sensory properties of both cooked and uncooked dehulled red lentil dal fortified with FeSO4 ·7H2 O, NaFeEDTA or FeSO4 ·H2 O at fortificant Fe concentrations of 800, 1,600 (both cooked and uncooked), or 2,800 ppm. Appearance, odor, and overall acceptability of cooked and uncooked samples were rated using a 9-point hedonic scale (1 = dislike extremely to 9 = like extremely). Taste and texture were rated for the cooked samples prepared as typical south Asian lentil meals. Significant differences in sensory quality were observed among all uncooked and cooked samples at both locations. Overall, scores for all sensory attributes and acceptability of uncooked lentil decreased with increasing concentration of Fe in the fortificant; however, Fe fortification (particularly with NaFeEDTA) had small effects on acceptability. Panelists from Saskatoon provided a wider range of scores than those from Bangladesh for all attributes of cooked lentil. Overall, sensory evaluation of Fe fortification using NaFeEDTA minimally affected consumer perception of color, taste, texture, odor, and overall acceptability of cooked lentil. Reliability estimates (Cronbach's alpha [CA]) indicated that consumer scores were generally consistent for all attributes of all lentil samples (mean CA > 0.80). NaFeEDTA was found to be the most suitable Fe fortificant for lentil based on consumer acceptability. Consumption of 45 to 50 g of NaFeEDTA-fortified lentil (fortificant Fe concentration of 1,600 ppm) per day meets the estimated average requirements (EARs) of Fe for humans (10.8 to 29.4 mg). PRACTICAL APPLICATION Iron fortification of dehulled lentil dal may change organoleptic attributes that can influence consumer acceptability. Sensory evaluation by consumers helps to determine the effect on appearance, odor, taste, texture, and overall acceptability of fortified lentils. In this study, consumer acceptability was evaluated with panelists who consume lentil regularly. Panelists provided significantly different scores for 5 sensory attributes for 10 uncooked and 3 cooked lentil samples. Panelists reliably preferred NaFeEDTA as the most suitable Fe fortificant for dehulled lentils for 5 attributes. Overall, lentil dal fortified with NaFeEDTA can offer a simple and low-cost solution to human health problems associated with iron-related malnutrition.

Abstract
Background School Feeding Program (SFP) is a targeted safety net program designed to provide educational and health benefits to vulnerable children. However, limited evidence exists regarding the effect of the intervention on the nutritional status and school attendance of children. The study is aimed at examining the effects of SFP on dietary diversity, nutritional status and class attendance of school children in Boricha district, Southern Ethiopia. Methods The study was conducted based on a representative data collected from 290 students drawn from the district. A school-based comparative cross-sectional study was conducted on school children aged 10–14 years. Data were collected using structured pretested questionnaire. The effects of SFP on dietary diversity score (DDS), class attendance rate, body-mass-index for age (BAZ) and height-for-age (HAZ) Z-scores were assessed using multivariable linear regression model. Results The finding showed significantly higher mean (±SD) of DDS in SFP beneficiaries (5.8 ± 1.1) than the non-beneficiaries (3.5 ± 0.7) (P < 0.001). BAZ and HAZ of the beneficiaries were also higher than their counterparts, which were (0.07 ± 0.93), (− 0.50 ± 0.86) and (− 1.45 ± 1.38), (− 2.17 ± 1.15) respectively (P < 0.001). The mean (±SD) days of absence from school for non-beneficiaries (2.6 ± 1.6) was significantly higher than that of the beneficiaries (1.3 ± 1.7) (P < 0.05). Conclusion Given the positive effects of the program in improving the DDS, nutritional status, and class attendance of school children, we strongly recommend scaling up the program to other food insecure areas.

Abstract
Background Transitional cell carcinoma is the most common bladder cancer of dogs. Cisplatin combined with piroxicam provides superior response rates, but unacceptable rates of nephrotoxicity. Tavocept is a chemoprotectant that has mitigated cisplatin toxicity and decreased the required infusion/diuresis volume in clinical trials in humans. Hypothesis/Objectives We hypothesized that Tavocept would decrease diuresis volume and time and facilitate safe administration of a cisplatin/piroxicam protocol to dogs with bladder cancer. Secondary objectives were to compare response rate and survival times to an historical comparator group treated without Tavocept. Animals Fourteen client‐owned dogs were prospectively enrolled. Methods Tumor volume was measured by computed tomography at days 0, 42, and 84. Dogs received combination Tavocept/cisplatin with a shortened diuresis protocol. A total of 4 doses was planned, with concurrent administration of piroxicam. Serial biochemical analyses were evaluated for azotemia. Results A 90‐minute infusion/diuresis time was used for all dogs. Three dogs (21%) had concurrent increases in serum creatinine (>2.0 mg/dL) and BUN (>42 mg/dL) concentrations; 2 of these dogs were isosthenuric. This frequency of nephrotoxicity is significantly less (P = 0.0406) than that of an historical control group treated without Tavocept. Overall response rate was 27%. Median survival time was comparable to historical controls (253 vs. 246 days). Conclusions and Clinical Importance Tavocept decreased the required diuresis time with cisplatin from > 6 hours to 90 minutes, while also decreasing occurrence of azotemia. Survival time was comparable, but the response rate was inferior to an historical comparator group. Further evaluation in other tumors susceptible to platinum agents is warranted.

Abstract
Iron (Fe) deficiency is a major human health concern in areas of the world in which diets are often Fe deficient. In the current study, we aimed to identify appropriate methods and optimal dosage for Fe fortification of lentil (Lens culinaris Medik.) dal with FeSO4·7H2O (ferrous sulphate hepta-hydrate), NaFeEDTA (ethylenediaminetetraacetic acid iron (III) sodium salt) and FeSO4·H2O (ferrous sulphate mono-hydrate). We used a colorimetric method to determine the appearance of the dal fortified with fortificants at different Fe concentrations and under different storage conditions. Relative Fe bioavailability was assessed using an in vitro cell culture bioassay. We found that NaFeEDTA was the most suitable fortificant for red lentil dal, and at 1600 ppm, NaFeEDTA provides 13–14 mg of additional Fe per 100 g of dal. Lentil dal sprayed with fortificant solutions, followed by shaking and drying at 75 °C, performed best with respect to drying time and color change. Total Fe and phytic acid concentrations differed significantly between cooked unfortified and fortified lentil, ranging from 68.7 to 238.5 ppm and 7.2 to 8.0 mg g−1, respectively. The relative Fe bioavailability of cooked fortified lentil was increased by 32.2–36.6% compared to unfortified cooked lentil. We conclude that fortification of lentil dal is effective and could provide significant health benefits to dal-consuming populations vulnerable to Fe deficiency.

Abstract
Silent circulation (SC) of wild polio viruses (WPV) when oral polio vaccine (OPV) use is stopped, could threaten eradication. We analyzed a model designed to develop theory about mechanisms and factors that lead to SC and how SC risks can be assessed using surveillance data. Prolonged low-level SC emerges as a threshold phenomenon through a mechanism related to balancing contributions of different populations to the effective reproduction number. Factors that promote this mechanism are many years of inadequate vaccination efforts, ongoing waning of immunity against transmission years after last OPV or WPV infection, low transmissibility of OPV, and high transmission conditions. Analyzing acute flaccid paralysis surveillance or environmental surveillance data by themselves cannot assess the risk that an SC threshold has been passed, but new methods to analyze them jointly could do so.
Waning immunity could allow transmission of polioviruses without causing poliomyelitis by promoting silent circulation (SC). Undetected SC when oral polio vaccine (OPV) use is stopped could cause difficult to control epidemics. Little is known about waning. To develop theory about what generates SC, we modeled a range of waning patterns. We varied both OPV and wild polio virus (WPV) transmissibility, the time from beginning vaccination to reaching low polio levels, and the infection to paralysis ratio (IPR). There was longer SC when waning continued over time rather than stopping after a few years, when WPV transmissibility was higher or OPV transmissibility was lower, and when the IPR was higher. These interacted in a way that makes recent emergence of prolonged SC a possibility. As the time to reach low infection levels increased, vaccine rates needed to eliminate polio increased and a threshold was passed where prolonged low-level SC emerged. These phenomena were caused by increased contributions to the force of infection from reinfections. The resulting SC occurs at low levels that would be difficult to detect using environmental surveillance. For all waning patterns, modest levels of vaccination of adults shortened SC. Previous modeling studies may have missed these phenomena because (1) they used models with no or very short duration waning and (2) they fit models to paralytic polio case counts. Our analyses show that polio case counts cannot predict SC because nearly identical polio case count patterns can be generated by a range of waning patterns that generate different patterns of SC. We conclude that the possibility of prolonged SC is real but unquantified, that vaccinating modest fractions of adults could reduce SC risk, and that joint analysis of acute flaccid paralysis and environmental surveillance data can help assess SC risks and ensure low risks before stopping OPV.

Abstract
Programmed death ligand 1 (PD-L1) expression in antigen-presenting cells and tumors can inhibit T cell-mediated immunity. In this study, PD-L1 mRNA and protein expression was evaluated in canine B cell lymphoma (CLL17-71), large T-cell leukemia (CLGL-90), B cell leukemia (GL-1) and primitive leukocyte round cell neoplasia (CLL-1390). Variable PD-L1 mRNA and protein were observed in these cells with high endogenous expression present in CLL17-71 cells. PD-L1 protein was also observed in canine patient B cell lymphoma tissues using immunostaining. PD-L1 and signal transducer and activator of transcription 1 ( STAT1 ) mRNA expression were reduced in the presence of mitogen-activated protein kinase kinase 1.2 (MEK1/2) inhibitors RDEA119 and AZD6244 in CLL 17-71 cells. RDEA119 had similar effect on PD-L1 and STAT-1 in IFN-γ activated CLL-1390 cells. Overall, these results indicate that PD-L1 is expressed in canine B cell lymphoma. Its inhibition by MEK1/2 inhibitors suggests a possible treatment strategy using targeted drugs which likely could enhance antitumor immune response.

Abstract
OBJECTIVES This study compared the effects of consuming different forms (bite size, puree) and two fruit types (guava, papaya) on glycemic response (GR) in elderly and young adults. DESIGN This study was conducted using a randomized, crossover design. PARTICIPANTS Nineteen healthy participants (9 elderly, 10 young adults) were recruited from the general public in Singapore. INTERVENTION Participants consumed glucose (reference food) on three occasions and test fruits (guava bites, guava puree, papaya bites, and papaya puree) on one occasion each. MEASUREMENTS Blood glucose was analyzed prior to consuming the test food, at 15, 30, 45, 60, 90 and 120 minutes after food consumption. RESULTS The incremental area under the blood glucose response curve (iAUC) over 120 minutes for all the treatments was significantly lower than glucose (all P < 0.001). All fruit forms and types studied were low glycemic index (GI) (guava bites: 29; papaya bites: 38; papaya puree: 42; guava puree: 47), albeit a significant difference in GI between the treatments was found (P = 0.003). Elderly exhibited significantly greater GR than young participants (P = 0.019). CONCLUSION Although fruit form influences GR in the elderly and young adults, all fruit types and forms studied were found to be low GI. This study indicates that fruits are a valuable source of nutrient irrespective of the form of delivery in elderly and young adults. This study was registered at www.anzctr.org.au as ACTRN12614000655640.

Abstract
BACKGROUND Good nutrition and appropriate child feeding are vital in early stages of child development, particularly in the first 1000 days of life. OBJECTIVE To assess the adoption of infant and young child feeding practices of World Health Organization, dietary intake, and level of undernutrition in children <2 years of age. METHODS Baseline cross-sectional study was conducted (January-June 2013) in purposively selected rural communities of Halaba and Zeway, Ethiopia (N = 383 mother-child pairs, randomly selected). RESULTS Overall prevalence of stunting, wasting, and underweight was 45%, 9%, and 28% in Halaba, and 33%, 7%, and 15% in Zeway, respectively; higher levels of stunting (54% in Halaba and 36% in Zeway) were observed in 6 to 24 months; stunting and underweight, but not wasting, differed by age ( P < .001) in Halaba. Median dietary diversity score in both communities was 2 with 61% to 65% of children consuming 0 to 2 food groupings. Except protein in all age and iron in 12 to 24 months, median intake of energy, iron, zinc, and calcium (and associated nutrient densities) was below the estimated needs that should come from complementary foods in both communities (in subsample). Early initiation of breast-feeding and exclusive breast-feeding was 63% and 86% in Halaba and 92% and 93% in Zeway, respectively ( P < .001). Children receiving minimum acceptable diet were 6% and 9% in Halaba and Zeway, respectively. CONCLUSIONS The high levels of stunting and suboptimal feeding practices as well as low dietary diversity scores, energy, and nutrient intake in both communities, particularly in Halaba, indicate a need to improve/strengthen nutrition strategies for complementary feeding children in these areas.

Abstract
Complementary foods (CFs) in Ethiopia are cereal based and adding locally grown pulses (legumes) to CF would provide needed nutrients. To assess the effects of nutrition education (NEd) using Health Belief Model (HBM) in promoting pulses for CF, a 6-month quasi-experimental study was conducted in 160 mother-child pairs. Knowledge, attitude, and practice (KAP) questions were given to mothers at baseline, midline, and endline, along with anthropometric measurements of children. NEd involving discussions and recipe demonstrations was given twice monthly for 6 months to the intervention group (n = 80) while control mothers received usual education. At baseline, mothers' KAP scores were low at both sites; at 3 and 6 months of NEd, mean KAP scores of mothers increased (p < 0.05) compared to the control site. Significant improvements in children's mean weight, weight for height, and weight for age occurred in the intervention site only. Nutritional status of children improved after providing mothers with pulse-based NEd.

Abstract
BACKGROUND Maternal and child under nutrition is highly prevalent in low-income and middle-income countries, resulting in substantial increases in mortality and overall disease burden. The aim of this baseline survey was to determine the association between selected maternal characteristics, maternal nutritional status and children's nutritional status. METHODS AND FINDINGS A survey with a cross sectional design was conducted between September and October 2012 in Hula, Ethiopia. The study subjects were 197 mothers of children between the ages of 6 and 23 months. Weight and height (mothers) or recumbent length (children) were measured using calibrated, standardized techniques. Seven percent of children were below -2 weight for height Z score (WHZ), 11.5% were below -2 height for age Z score (HAZ) and 9.9% were below -2 weight for age Z score (WAZ). Maternal anthropometrics were associated with child nutritional status in the bivariate analysis. Maternal BMI (r = 0.16 P = 0.02) and educational status (r = 0.25 P = 0.001) were correlated with WHZ of children while maternal height (r = 0.2 P = 0.007) was correlated with HAZ of children. After multivariate analysis, children whose mothers had salary from employment had a better WHZ score (P = 0.001) and WAZ score (P<0.001). Both maternal BMI and maternal height were associated with WHZ (P = 0.04) and HAZ (P = 0.01) score of children. CONCLUSION Having a mother with better nutritional status and salaried employment is a benefit for the nutritional status of the child. The interrelationship between maternal and child nutritional status stresses the value of improving maternal nutritional status as this should improve both maternal and child health outcomes. Therefore strategies to improve nutritional status of children should also include improving the nutritional status of the mother and empowering her financially.

Abstract
BACKGROUND Nutritious complementary foods are needed in countries where undernutrition and stunting are major problems, but mothers may be reluctant to change from traditional gruels. OBJECTIVE To test whether a recipe-based complementary feeding education intervention would improve knowledge and practice of mothers with young children in Hula, Ethiopia. METHODS A baseline survey of 200 eligible, randomly selected mother-child pairs gathered data on sociodemographic characteristics, food security status, knowledge and practices concerning complementary feeding, food group intakes of children aged 6 to 23 months by 24-hour recalls, and children's anthropometric measurements. Twice a month for 6 months, women in the intervention group received an education session consisting of eight specific messages using Alive and Thrive posters and a demonstration and tasting of a local barley and maize porridge recipe containing 30% broad beans. The control group lived in a different area and had no intervention. RESULTS At 6 months, knowledge and practice scores regarding complementary feeding were significantly improved (p < .001) in the intervention group but not in the control group. The intervention resulted in improvement of children's dietary diversity, as well as mean intake of energy and selected nutrients, compared with children in the control group. Changes in height and weight did not differ between the two groups. CONCLUSIONS Community-based nutrition education over 6 months that included demonstration of a local porridge recipe with broad beans added improved the complementary feeding practices of caregivers and the nutritional status of their young children.

Abstract
Overweight and obesity are associated with several life-threating comorbidities, including type 2 diabetes and cardiovascular disease. Obesity is a growing health concern in North America, with some groups experiencing higher levels of obesity than others. One group of particular interest is urban Aboriginal youth because they are a quickly growing population who experience high rates of obesity. Obesity is a complex condition with many contributing factors, diet being one of the primary contributors. In this article, we discuss the findings from an ethnographic study that examined determinants of diet for urban Aboriginal youth. Results revealed two themes: (a) Traditions and Sharing, and (b) The Struggle. The findings with Traditions and Sharing showed that food-sharing networks are often used to acquire traditional food. Traditional foods were believed to be healthy and desired by the participants. The theme The Struggle provides insight into the daily challenges the participants faced with food insecurity. Health promotion professionals need to consider the multiplicity of determinants of diet for urban Aboriginal youth in order to plan and implement culturally appropriate health promotion programs.

Abstract
BACKGROUND/OBJECTIVES Previous studies have demonstrated the satiating properties of soups compared with solids; however, the mechanisms controlling soup-induced satiety are unknown. This study aimed to understand the physiological mechanisms causing soup to be more satiating. SUBJECTS/METHODS A total of 12 volunteers were tested on three occasions after a solid meal, chunky soup or smooth soup test meal for gastric emptying (GE) using the sodium [1-¹³C] acetate breath test, satiety using visual analog scales (VAS) and glycaemic response (GR) using finger prick blood samples. RESULTS There was a significant difference in GE half-time (P=0.022) and GE ascension time (P=0.018), with the longest GE times for the smooth soup and the shortest for the solid meal. The GR area under the curve was significantly different between meals (P=0.040). The smooth soup had the greatest GR (87.0 ± 49.5 mmol/l/min), followed by the chunky soup (65.4 ± 48.0 mmol/l/min), with the solid meal having the lowest GR (61.6 ± 36.8 mmol/l/min). Volunteers were fuller after the smooth soup compared with solid meal (P=0.034). CONCLUSIONS The smooth soup induced greater fullness compared with the solid meal because of a combination of delayed GE leading to feelings of gastric distension and rapid accessibility of nutrients causing a greater glycaemic response.

Abstract
BACKGROUND Satraplatin is the 1st orally bioavailable platinum anticancer drug. OBJECTIVE Our objectives were to evaluate efficacy in vitro against a canine cancer cell line, to determine the maximally tolerated dose (MTD) of satraplatin in tumor-bearing dogs, to identify the dose-limiting and other toxicities in dogs, and to record pharmacokinetics (PK). ANIMALS Dogs with macro- or microscopic malignant neoplasia. METHODS D17 canine osteosarcoma cells first were evaluated in a clonogenic survival assay. Then, dogs with a diagnosis of malignant neoplasia were prospectively entered in standard 3 + 3 cohorts. Additional patients were entered at the MTD to assess efficacy. Total and free platinum (by ultrafiltrate) concentrations were determined with inductively coupled plasma mass spectroscopy. RESULTS Satraplatin inhibited clonogenic survival in vitro at clinically relevant and achievable concentrations. Twenty-three dogs were treated, 14 with PK evaluation. The MTD was 35 mg/m(2)/d for 5 days, repeated every 3-4 weeks. Bioavailability was 41%. PK variables (mean ± SD) at the MTD included T(max) 1.8 (± 0.7) hours, C(max) 72 (± 26) ng/mL, area under concentration (AUC)(0-24 h) 316 (± 63) h × ng/mL, and MRT 7 (± 1.3) hours. Higher AUC after the 5th versus the 1st dose suggested drug accumulation. Interestingly, platelets consistently reached nadir sooner than did neutrophils (day 14 versus 19). Myelosuppression was dose-limiting and gastrointestinal toxicity was mild. CONCLUSIONS AND CLINICAL IMPORTANCE Satraplatin was well tolerated in tumor-bearing dogs, thus warranting further investigation in a phase II trial.

Abstract
OBJECTIVE Although Aboriginal children seem to be more susceptible to developing obesity and metabolic disorders than other ethnic groups in Canada, few studies have examined adiposity comprehensively in this population. The purpose of this study was to assess total and central adiposity in Canadian Aboriginal and Caucasian children matched by age, gender and maturity. METHODS A total of 212 Aboriginal and 204 Caucasian children (8-17 years) were recruited. Heights, weights and waist circumferences were measured and classified using international standards. Dual energy x-ray absorptiometry (DXA) indicated relative total body and trunk fatness. Age of peak height velocity was predicted from somatic growth. Descriptives with independent t-tests and Chi-square analyses were run to detect ethnic differences. ANCOVA was used to assess differences in total body and trunk fatness (covariates height, chronological age and biological age) in girls and boys separately. RESULTS Overweight/obesity and central adiposity were more prevalent in Aboriginal children compared with Caucasian children (p < 0.05). Ethnic differences in total body and trunk fatness were also significant, with Aboriginal girls and boys presenting, on average, 5.4% and 6.0% more total body fatness and 7.6% and 8.3% more trunk fatness, than Caucasian girls and boys, respectively (p < 0.01). CONCLUSION Canadian Aboriginal children have greater prevalence of overweight/obesity and central adiposity, and higher relative total body fatness and trunk fatness than their Caucasian peers, which may predispose them to cardiovascular and metabolic disorders at a very young age. Longitudinal research is needed to confirm the associated health risks in this population.

Abstract
An 8-year-old castrated male mixed-breed dog had an ill-defined hemorrhagic and painful lesion in the base of the claw of the second digit of the right forelimb. Radiographically, the expansile and lytic lesion affected the distal phalanx. The digit was amputated and submitted for histologic examination. Histologically, the distal phalanx was largely replaced by a mass composed of variably sized cavernous vascular spaces lined by a single layer of flattened endothelial cells. A similar mass was in the subcutis adjacent to the distal phalanx. The benign vascular proliferation involving the medulla of bone and a second tissue type in this dog is consistent with skeletal-extraskeletal angiomatosis as described in humans. To the authors' knowledge, this is the first report of skeletal-extraskeletal angiomatosis in the veterinary literature.

Abstract
Copper-64 emits beta(+) and beta(-) particles suitable for positron emission tomography and radioimmunotherapy (RIT) of cancer. Copper-64-labelled antibodies have caused complete responses in laboratory animal RIT studies at far lower radiation doses than traditionally prescribed. The intracellular localization of copper radioisotopes may lead to cytotoxic effects by mechanisms beyond ionizing radiation damage. The purpose of this research was to develop a model using both internalizing and non-internalizing antibodies for direct comparison in future RIT studies using the same animal model of cancer. The monoclonal antibodies, cBR96 and cT84.66, were conjugated with N-hydroxysulfosuccinimidyl DOTA. All conjugates retained high immunoreactivity and labelled efficiently with (64)Cu with high specific activity and radiochemical purity. Twenty-four hour biodistributions determined in LS174T tumour-bearing nude mice demonstrated low organ and high tumour uptakes for both monoclonal antibodies. This model constitutes a promising system for elucidating whether internalization of (64)Cu is responsible for an enhanced tumour cytotoxicity in vivo.

Abstract
BACKGROUND Patient-focused care provided by an interprofessional team has long been presented as the preferred method of primary care delivery. Community pharmacists should and can provide leadership for many clinical and managerial activities within the primary care team. OBJECTIVE To determine the extent to which community pharmacists are prepared to be members of the health care team, and to assess their support for general expansion of clinical responsibilities. METHODS A mail questionnaire (in either English or French) was sent to 1500 community pharmacists between February and April 2004. Respondents were asked to indicate the necessity of pharmacy leadership for a range of clinical and managerial services associated with a primary care team. Respondents were also asked to indicate the extent to which they should be more involved in drug therapy selection and monitoring, as well as assuming greater responsibility for treating both minor and chronic illnesses. RESULTS The response rate was 35.2% (470/1337) with the highest response rate in the Prairie provinces (40.6%) and the lowest in Quebec (24.4%). Most pharmacists in the study did not advocate a strong leadership role for non-discipline-specific clinical and managerial activities. Most of them indicated that community pharmacists should be more involved in selecting (69.9%) and monitoring (81.0%) drug therapy, and be more responsible for treating minor illnesses (72.0%). Support for more responsibility declined to 50% for chronic illnesses. CONCLUSIONS The findings of the study suggest substantial variability among pharmacists in their perception of the need for pharmacy leadership across 16 clinical and managerial activities.

Abstract
Survivin, an inhibitor of apoptosis, is overexpressed in human invasive transitional cell carcinoma (TCC) of the urinary bladder. Survivin expression in canine TCC has not been defined. This study was designed to compare survivin expression between canine TCC and normal urinary bladder tissue. Reverse-transcriptase polymerase chain reaction (PCR) and immunohistochemistry (IHC) were performed on fresh-frozen and formalin-fixed tissues, respectively. All TCC tissues (n = 6) and 11/22 normal tissues assessed by PCR were positive for survivin. This difference was not significant (P = 0.06). With regard to IHC, 28/41 TCC samples were positive for nuclear survivin, whereas 0/46 normal tissues had nuclear immunoreactivity (P < 0.001). Cytoplasmic immunoreactivity did not significantly differ between TCC (7/41) and normal tissues (17/46) (P = 0.07). We conclude that nuclear survivin is present in canine TCC, but not in normal bladder urothelium. Future studies will evaluate the role of nuclear survivin in TCC development and as a potential therapeutic target.

Abstract
Certain beverages contribute energy, protein, vitamins, and minerals. North American adolescents have shifted their beverage intake from predominantly milk to predominantly sugary beverages. Intake of these sugary beverages, in sufficient quantity, may increase the risk of bone fractures, may contribute to obesity, and may lead to tooth decay. This study evaluated the effectiveness of a school-nutrition education program (Fluids Used Effectively for Living) on nutrition knowledge, attitude, and self-reported behavior of grade 9 students in Saskatchewan, Canada. Two classes of grade 9 students, 1 (n = 33) in a high school in Saskatoon (n = 33) and 1 (n = 24) in a large high school in Prince Albert, Saskatchewan, received the peer educator intervention. Two other classes in the 2 cities (n = 24 and n = 24, respectively) were controls. Six sessions of Fluids Used Effectively for Living nutrition education were delivered by using 2 peer educator models (multiple and single), and the intervention was delivered in a 45-minute weekly class session over a 6-week period. After the intervention, students in these 2 peer educator classes decreased their sugary beverage intake significantly, which was sustained for 3 months. Students in the control self-taught class increased their juice intake at the end of the year. The significant decrease of juice and sugary beverage intakes in the single model peer educator class disappeared after Bonferroni correction. Carbonated sugary beverage intake of students in the control self-taught classes declined, but it was not sustainable at the 3-month follow-up. A peer educator school-based nutrition education approach can lead to a decrease in sugary beverage intake in high school children.
