Increased frequency of the autism broader phenotype in mothers transmitting etiological CNVs to sons affected by Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder (ASD) is a frequent and complex neurodevelopmental disorder, characterized by impairments in social communication and repetitive behaviors and with a high male to female ratio: ~4:1. Genetic factors, including rare Copy Number Variants (CNVs), have a substantial impact in ASD risk1, and are associated with specific phenotypic manifestations2. Recent studies reported that rare inherited CNVs are enriched in mothers of ASD children compared with mothers of controls and are preferentially transmitted from mothers to ASD children suggesting a sex bias in CNV transmission; further, the imbalanced transmission of small pathogenic CNVs from unaffected mothers to their sons with ASD has been described3,4. An increased prevalence of autism-like personality traits is found in unaffected relatives of ASD children, suggesting a genetic liability of a broader autism phenotype (BAP)5. The BAP in parents of autistic children can be assessed by the Social Responsiveness Scale (SRS)6 and Broad Autism Phenotype Questionnaire (BAPQ)7 reports. The SRS is 65-item questionnaire to identify sub-clinical social impairments and interpersonal behaviour in individuals. The BAPQ is a 36-item questionnaire measures social aloofness, rigid personality, and pragmatic language deficits in both parents and children.

Pinning Down Identity in Social Media: Food Cultural Transfer on Pinterest

This research has been conducted within the realm of where today’s digital media society and the timeless concept of cultural identity overlap. The aim of this thesis is to explore the nature of online cultural identity management. By focusing on the social media platform, Pinterest, this study considers the food-pinning behavior of a group of Americans living in Finland and connects their online actions with their cultural identity. Through an examination of Pinterest as a social space, and even a third place, the relative theoretical literature provides and interesting background for a contemporary discussion on the matter. Literature on food as a cultural marker is also brought into consideration. Using the methods of introspection and an adapted version of virtual ethnography, a study was conducted, and ultimately, the analysis of data obtained from the Pinterest boards of ten individuals shows that the vast majority of food-related information in this setting is US-sourced. A questionnaire provides further insight into the individuals’ Pinterest usage. I argue that pinning is an act of online identity management, whether it is a conscious act or a situational effect, and that using Pinterest maintains and even strengthens these individuals’ cultural identity as Americans. This study adds to current discussions pertaining to transnationalism, globalization, and online cultural identity, as well as opens channels for further research on this dynamic topic, which is needed to understand ourselves as cultural beings in the digital age.

EDUCATION, TRAINING AND AWARENESS OF LAWS AS DETERMINANTS OF COMPLIANCE WITH PLANT PROTECTION LAW: THE CASE OF PESTICIDE USE PRACTICES IN TANZANIA

Pesticide residues in food and environment pose serious health risks to human beings. Plant protection laws, among other things, regulate misuse of agricultural pesticides. Compliance with such laws consequently reduces risks of pesticide residues in food and the environment. Studies were conducted to assess the compliance with plant protection laws among tomato farmers in Mvomero District, Morogoro Region, Tanzania. Compliance was assessed by examining pesticide use practices that are regulated by the Tanzanian Plant Protection Act (PPA) of 1997. A total of 91 tomato farmers were interviewed using a structured questionnaire. Purposive sampling was used in selecting at least 30 respondent farmers from each of the three villages of Msufini, Mlali and Doma in Mvomero District, Morogoro Region. Simple Random Sampling was used to obtain respondents from the sampling frame. Individual and social factors were examined on how they could affect pesticide use practices regulated by the law. Descriptive statistics, mainly frequency, were used to analyze the data while associations between variables were determined using Chi-Square and logistic regression model. The results showed that respondents were generally aware of the existence of laws on agriculture, environment and consumer health, although none of them could name a specific Act. The results revealed further that 94.5% of the farmers read instructions on the pesticides label. However, only 21% used the correct doses of pesticides, 40.7% stored pesticides in special stores, 68.1% used protective gear, while 94.5% always read instructions on the label before using a pesticide product. Training influenced the application rate of pesticide (p < 0.001) while awareness of agricultural laws significantly influenced farmers’ tendency to read information on the labels (p < 0.001). The results showed further that education significantly influenced the use of protective gears by farmers (p = 0.042). Education also significantly affected the manner in which farmers stored pesticide-applying equipment (p = 0.024). Furthermore, farmers’ awareness of environmental laws significantly (p = 0.03) affected farmers’ disposal of empty pesticide containers. Results of this study suggest the need for express provisions on safe use and handling of pesticides and related offences in the Act, and that compliance should be achieved through education rather than coercion. Results also suggest establishment of pesticide disposal mechanisms and structures to reduce unsafe disposal of pesticide containers. It is recommended that farmers should be educated and trained on proper use of pesticides. Farmers’ awareness on laws affecting food, environment and agriculture should be improved.

Removable orthodontic appliances: frequency and cleaning agents used by students and recommended by dentists

Aim: To evaluate the prevalence and hygiene habits of 13-19 years-old adolescent users of removable orthodontic appliances (ROA) and to determine hygiene methods for the appliances prescribed by dentists, in the city of Pelotas. Methods: The study had two stages. The first stage was a telephone interview with dentists. Dentists were interview by telephone calls in order to obtain information regarding the hygiene methods for cleaning acrylic appliances. Second stage was a cross-sectional study performed with schoolchildren. Children from public and private schools with secondary level were included in the sample. A questionnaire was applied to the students using any type of ROA. Questionnaires included demographic information and behavioral characteristics. Data collected were subjected to Chi-square test and logistic regression. Results: The prevalence of children using ROA was 5.4%. Students (89.7%) and dentists (47.2%) reported to prefer mechanical methods to clean their ROA. Cleaning with soup, hydrogen peroxide or effervescent tabs were less used. High frequency of use was associated with higher frequency of hygiene on the ROA. Conclusions: The prevalence of schoolchildren using removable appliances was low. The common cleaning method used by children and prescribed by dentists was mechanical. Hygiene frequency was significantly associated with the routine of use of the appliance and with the type of hygiene method.

Regional Disparities in Sedentary Behaviors and Meal Frequency in Iranian Adolescents: The CASPIAN-III Study

Background: The prevalence of obesity is increasing among Iranian youngsters like other developing countries. Objectives: This study was conducted to assess regional disparities in sedentary behaviors and meal frequency in Iranian adolescents. Patients and Methods: In this national survey, 5682 students aged 10 - 18 years from urban and rural districts of 27 provinces of Iran were selected via stratified multi-stage sampling method. The country was classified into four sub-national regions, based on criteria of the combination of geography and socioeconomic status (SES). Mean of meal frequency and physical activity levels as well as prevalence of omitting meals and sedentary behavior were compared across regions with different SES after stratifying with sex and age group. Results: Meal frequency in lower socio-economic regions was significantly higher than two other regions in 10 - 13 and 10 - 18 years old groups (P trend < 0.001). However, the mean of working hours with computer was linearly increased with increasing the SES in studied regions (P trend < 0.001), whereas the corresponding figure was not significant for the mean of watching TV (P trend > 0.05). Frequency of adolescents omitting their meals was higher in higher SES regions especially in West Iran (P < 0.001) in 10 - 13 years old age group. Having personal computer and working with it more than two hours per day mainly was observed in central Iran which ranked as the highest SES group. Conclusions: Efforts to ensure Iranian youth meet healthy food habits and screen time guidelines include limiting access to screen technologies and encouraging parents to monitor their own screen time is required.

Food intake of Macrobrachium rosenbergii during larval development

This work investigates the acceptance of different food types and sizes by Macrobrachium rosenbergii during each larval stage. Food intake of dry and wet formulated diets of four different size classes (250-425, 425-710, 710-1000 and 1000-1190 mum), as well as Artemia nauplii, was determined. Larvae of each zoeal stage were stocked in beakers and fed ad libitum. After 30-45 min, the digestive tract of each larva was observed under a stereomicroscope. Acceptance was evaluated by food intake frequency (FFI). There was no significant interaction (P<0.05) between inert diet size and FFI for each larval stage. Therefore, food intake during larval development is independent of food particle size. The ingestion of Artemia nauplii, was significantly higher by larvae between stages II and VI. Between stages VII and XI, FFI for Artemia nauplii and wet diet was similar, while the FFI of the dry diet was similar to live food between stages IX and XI. The wet diet was ingested by more than 50% of the larvae only from stage VII onwards, while the dry diet from stage VIII onwards. These results indicate that larvae could be fed Artemia nauplii only until stage VI. Diet supplementation should start from stage VII onwards, using food particles varying from 250 to 1190 mum.

ArmA methyltransferase in a monophasic Salmonella enterica isolate from food

The 16S rRNA methyltransferase ArmA is a worldwide emerging determinant that confers high-level resistance to most clinically relevant aminoglycosides. We report here the identification and characterization of a multidrug-resistant Salmonella enterica subspecies I.4,12:i:- isolate recovered from chicken meat sampled in a supermarket on February 2009 in La Reunion, a French island in the Indian Ocean. Susceptibility testing showed an unusually high-level resistance to gentamicin, as well as to ampicillin, expanded-spectrum cephalosporins and amoxicillin-clavulanate. Molecular analysis of the 16S rRNA methyltransferases revealed presence of the armA gene, together with bla(TEM-1), bla(CMY-2), and bla(CTX-M-3). All of these genes could be transferred en bloc through conjugation into Escherichia coli at a frequency of 10(-5) CFU/donor. Replicon typing and S1 pulsed-field gel electrophoresis revealed that the armA gene was borne on an ~150-kb broad-host-range IncP plasmid, pB1010. To elucidate how armA had integrated in pB1010, a PCR mapping strategy was developed for Tn1548, the genetic platform for armA. The gene was embedded in a Tn1548-like structure, albeit with a deletion of the macrolide resistance genes, and an IS26 was inserted within the mel gene. To our knowledge, this is the first report of ArmA methyltransferase in food, showing a novel route of transmission for this resistance determinant. Further surveillance in food-borne bacteria will be crucial to determine the role of food in the spread of 16S rRNA methyltransferase genes worldwide.

Consumers knowledge about dietary fibre : Results of a survey questionnaire in Hungary and Romania

Dietary fi bres (DFs) are essential components of the balanced diet. Even though the adequate level of their consumption can be ensured from several natural (e.g. fruit, vegetables, legumes) and ‘artifi cial’ sources (e.g. functional foods), the consumed levels are below the recommendations. To analyse the Hungarian and Romanian consumers’ knowledge level, their perceptions of the health benefi ts associated with fi bre, as well as the recognition of the potential information sources, a survey questionnaire was conducted with the total of 713 consumers. Results showed that the level of knowledge about DFs was not adequate. Internet was found to be widely used and identifi ed as one of the most appropriate information sources to encourage the consumption of DF. It was a favourable result that three-quarter of the respondents was interested in the topic of healthy food consumption; however, just less than half of them took into consideration the label information during their shopping decisions. To increase the consumption of DF and to support the responsibility and conscious consumer decisions steps must to be done (e.g. education of children, pointing out of the sources). For this purpose, modern information technology and communication channels fi tting to the consumers’ cultural and personal particularities can be utilized.

Concurrent validity of the Swedish version of the life-space assessment questionnaire

BACKGROUND: The Life-Space Assessment (LSA), developed in the USA, is an instrument focusing on mobility with respect to reaching different areas defined as life-spaces, extending from the room where the person sleeps to mobility outside one's hometown. A newly translated Swedish version of the LSA (LSA-S) has been tested for test-retest reliability, but the validity remains to be tested. The purpose of the present study was to examine the concurrent validity of the LSA-S, by comparing and correlating the LSA scores to other measures of mobility. METHOD: The LSA was included in a population-based study of health, functioning and mobility among older persons in Sweden, and the present analysis comprised 312 community-dwelling participants. To test the concurrent validity, the LSA scores were compared to a number of other mobility-related variables, including the Short Physical Performance Battery (SPPB) as well as "stair climbing", "transfers", "transportation", "food shopping", "travel for pleasure" and "community activities". The LSA total mean scores for different levels of the other mobility-related variables, and measures of correlation were calculated. RESULTS: Higher LSA total mean scores were observed with higher levels of all the other mobility related variables. Most of the correlations between the LSA and the other mobility variables were large (r = 0.5-1.0) and significant at the 0.01 level. The LSA total score, as well as independent life-space and assistive life-space correlated with transportation (0.63, 0.66, 0.64) and food shopping (0.55, 0.58, 0.55). Assistive life-space also correlated with SPPB (0.47). With respect to maximal life-space, the correlations with the mobility-related variables were generally lower (below 0.5), probably since this aspect of life-space mobility is highly influenced by social support and is not so dependent on the individual's own physical function. CONCLUSION: LSA was shown to be a valid measure of mobility when using the LSA total, independent LS or assistive LSA.

Etapas de cambio conductual relacionado al consumo de frutas y verduras en escolares de Bogotá, Colombia

Objetivo: Describir la relación de las etapas de cambio conductual frente al consumo de frutas y verduras con el estado nutricional en un grupo de escolares de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio de corte transversal en 1.922 niños y adolescentes entre 9 y 17 años, pertenecientes a nueve instituciones educativas oficiales de Bogotá. Se aplicó de manera auto-diligenciada el cuestionario de cambio de comportamiento (CCC-Fuprecol) validado en el “estudio FUPRECOL” y se calculó el Índice de Masa Corporal (IMC) como marcador del estado nutricional. Se calcularon prevalencias y se establecieron asociaciones mediante modelos de regresión logística binaria. Resultados: La muestra estuvo conformada por 1.045 niños-niñas y adolescentes vs hombres (45.6%) y mujeres (54.3%) y 877. La mayor proporción de consumo de frutas en el subgrupo de hombres (niños entre 9 y 12 años vs. adolescentes entre 13 y 17 años) se observó en la etapa de mantenimiento, (53.3 % vs. 38.8 %, X2 p<0.001), seguido de preparación/acción (25.0 % vs. 32.4 %, X2 p<0.001). En mujeres entre 9 y 12 años, la mayor proporción se ubicó en la etapa de mantenimiento (54.4 %), a diferencia de las adolescentes entre 13 y 17 años que acusaron mayor frecuencia la etapa de preparación/acción (42.0 %). Se observó que pertenecer al grupo de mujeres, se asociaba como variable para el cumplimiento de la recomendación mínima de frutas y verduras con valores de OR 1.54 (IC95% 1.22-1.93) y OR 1.48 (IC95% 1.19-1.84), respectivamente. Conclusiones: Aproximadamente, 66 % de los participantes tienen la intención o la voluntad de cumplir las recomendaciones de consumo de frutas y verduras. La identificación temprana de niños y adolescentes con bajo consumo de alimentos vegetales, permitirá implementar intervenciones para promover comportamientos saludables a fin de prevenir el riesgo cardiometabólico en la edad adulta.

Prevalencia y factores asociados al consumo de bebidas azucaradas en escolares de 9 a 17 años de Bogotá, Colombia: Estudio FUPRECOL

Objetivo: Determinar la prevalencia y los factores asociados al consumo de bebidas azucaradas en una población escolar de Bogotá, Colombia, pertenecientes al estudio FUPRECOL. Métodos: Estudio descriptivo y transversal, realizado en 8136 niños y adolescentes en edad escolar entre 9 y 17 años de Bogotá, Colombia. El peso, la estatura, el índice de masa corporal (IMC), la circunferencia de cintura y el porcentaje de grasa, se recogieron como marcadores antropométricos y de composición corporal. El consumo de bebidas azucaradas (bebidas carbonatadas, jugos ultra-procesados y/o Té), y los factores asociados (sexo, edad, obesidad abdominal, clasificación del IMC, grado de estudios de la madre/padre, y nivel nutricional por cuestionario “Krece plus”), se recogieron por encuesta estructurada. Se establecieron asociaciones mediante la construcción de modelos de regresión logística simple. Resultados: De la población general, el 58,4% eran mujeres. En función al sexo, los varones acusaron la mayor ingesta de “bebidas carbonatadas” con una frecuencia semanal y diaria de 70,9% y 21,0%, respectivamente, seguido de “jugos ultra- procesados” (64,4% semanal vs. 11,3% diario). En ambos sexos, la prevalencia de obesidad abdominal fue mayor en los escolares que respondieron consumir diariamente “bebidas carbonatadas” (23,3%), “jugos ultra-procesados” (13,2%) y “bebidas Té” (9,7%). La edad, el grado de educación de los padres y el nivel nutricional, se asociaron como factores predisponentes al consumo diario de “bebidas carbonatadas”. Conclusión: El consumo de bebidas azucaradas cambia por los factores analizados. Se recomiendan intervenciones integrales en las que estén involucrados los componentes nutricional y educativo entre los niños y adolescentes de Bogotá, Colombia.

RESUMEN INTRODUCCION: Los riesgos psicosociales en los últimos años han venido tomando importancia debido a que están íntimamente relacionados con el desarrollo de enfermedades producidas por el estrés tanto en la población general como en la comunidad trabajadora. De esta manera los riesgos psicosociales se convierten en un foco de interés cuando de prevención en el trabajo se trata. OBJETIVO: Identificar los factores de riesgo psicosocial a los cuales se encuentran expuestos los trabajadores de una empresa agrícola y alimenticia ubicada en Chile en el año 2016. MÉTODOS: Se llevó a cabo un estudio de corte transversal con datos secundarios procedentes de 194 trabajadores. Se incluyeron variables socio-demográficas, laborales y las relacionadas con el riesgo psicosocial. Como instrumento se utilizó el cuestionario ISTAS 21, que permite la evaluación y prevención de dicho riesgo, mide las dimensiones de la exposición psicosocial y de la salud, el estrés y la satisfacción. En el análisis descriptivo en las variables cuantitativas se calcularon las medidas de tendencia central media, mediana y medidas de dispersión como rango y desviación estándar. En las cualitativas se calculó la frecuencia absoluta y porcentaje, se utilizó el programa estadístico SPSS versión 22. RESULTADOS: El mínimo de edad fue de 25 y el máximo de 55 años. Los grupos etarios predominantes fueron entre 25-30 años y 36-45 años. Se observó que la mayoría de los miembros de esta organización estuvo conformada por hombres. El nivel alto de riesgo psicosocial percibido por los trabajadores por porcentaje en tres de las cinco dimensiones se registró de la siguiente manera: Trabajo activo y posibilidades de desarrollo (48.5%); apoyo social y calidad de liderazgo (52.0%) y doble presencia (52.6%). Las subdimensiones que más se vieron afectadas por el riesgo alto fueron: influencia en el trabajo (69.4%); control sobre el tiempo de trabajo (53.1%); posibilidades de desarrollo en el trabajo (50.0%); claridad de rol (66.8%); calidad de la relación con superiores (52.6%), compañeros (48.8%) y carga de tareas domésticas (50.0%). CONCLUSIONES: El nivel de riesgo psicosocial percibido por los trabajadores fue de Riesgo Alto en tres de las cinco dimensiones del cuestionario SUSESO ISTAS-21 (dimensión Trabajo activo y posibilidades de desarrollo; apoyo social y calidad de liderazgo y doble presencia). A partir de estos hallazgos se concluye que si hay presencia importante de situaciones desfavorables para la salud mental de los trabajadores y un riesgo psicosocial alto que es necesario enfrentar a través de la implementación de estrategias encaminadas a reducir el riesgo en las subdimensiones que más alto riesgo presentaron.

Assessing Household Food Waste in Italy: A Methodology for Detecting Drivers and Quantities

It has been estimated that one third of edible food destined for human consumption is lost or wasted along the food supply chain globally. Much of the waste comes from Global North, where consumers are considered as the bigger contributors. Different studies tried to analyze and estimate the Household Food Waste (HFW), especially in UK and Northern Europe. The result is that accurate studies at national level exist only in UK, Finland and Norway while no such studies are available in Italy, except for survey- based researches. Though, there is a widespread awareness that such methods might be not able to estimate Food Waste. Results emerging from literature clearly suggest that survey estimate inferior amounts of Food Waste as a result, if compared to waste sorting and weighting analysis or to diary studies. The hypothesis that household food waste is under-estimated when gathered through questionnaires has been enquired into. First, a literature review of behavioral economics and heuristics has been proposed; then, a literature review of the sector listing the existing methodologies to gather national data on Household Food Waste has been illustrated. Finally, a pilot experiment to test a mixed methodology is proposed. While literature suggests that four specific cognitive biases might be able to affect the reliability of answers in questionnaires, results of the present experiment clearly indicate that there is a relevant difference between how much the individual thinks to waste and he/she actually does. The result is a mixed methodology based on questionnaire, diary and waste sorting, able to overcome the cons of each single method.
