Food, nutrition and public health in contemporary Spain, 1900-1936

Within the context of the health reforms introduced in Spain in the early 20th century and the influence of international health organisations on their development, this article analyses the growing interest that surrounded nourishment and food-related problems at that time in relation to healthcare, the diagnosis provided by hygienists of such problems, and the public health measures applied to resolve them. The issue of hygienic diet and the collective aspect of nutritional problems became priorities in the field of healthcare. Two of the most prominent initiatives involved setting up a Department of Nutrition and Food Hygiene and Bromatological Technique during the early years of the Second Republic, as part of the National School of Health, as well as a Food Hygiene Service. Spanish hygienists underlined the importance of education and the dissemination of information about food hygiene, health and nutrition, in order to overcome the qualitative and quantitative deficiencies observed in the average diet of the Spanish population.

Effect of oral hygiene education and motivation on removable partial denture wearers: longitudinal study

The purpose of this study was to determine the effect of two different preventive oral hygiene education and motivation programmes on the plaque and gingival index, as well as denture hygiene of patients provided with removable partial denture (RPD) during a 12-month follow-up.A total of 53 partially edentulous patients were recruited for this study. The presence or absence of plaque and gingival bleeding by gentle probing was scored on all tooth surfaces at the preliminary visit. The plaque and gingival indexes were measured using the Loe index. Following treatment, the patients were randomly divided into three groups. In Control Group I, subjects were instructed to continue their personal oral hygiene routine. In Group II, participants were given verbal instructions and a self-educational manual on oral hygiene without illustrations. In Group III, oral hygiene guidance was delivered using a combination of verbal instructions and a self-teaching manual. To evaluate the effect of the different modes of instruction, the presence or absence of plaque and gingival bleeding was scored on all tooth surfaces (day zero examination) and re-examined 7, 15 and 30 days, 3, 6 and 12 months following RPD placement. The state of denture hygiene was evaluated 7, 15 and 30 days and 3, 6 and 12 months following rehabilitation. Parametric statistics was applied to dental plaque and gingival indexes. For accumulation of plaque and calculus on the RPD, non-parametric statistic was applied.The frequency of plaque found during the preliminary visit was higher than that found in the other periods. With regard to gingival index, significant difference was found between the preliminary visit examination and other periods. There was a significant difference in the plaque accumulation on the denture surface between groups I and III.The different methods of oral hygiene instruction used in this study indicate that the type of education was not of significant importance.

Beach nourishment impact on Posidonia oceanica: Case study of Poniente Beach (Benidorm, Spain)

The importance of nourishment processes on the beaches of Mediterranean Sea has been increasing since the end of the 20th century due to its socio-economical awareness (tourismboost) and environmental implications (possible impact on Posidonia oceanica meadows and important processes of dredging and earth movements). However, in many cases, and especially in eastern Spain, relevant actions have been made which had caused that, after 20 years, the beaches in which these works were carried out will be in a similar situation with the original one. The present study analyzed the Poniente Beach (Benidorm, Spain), a beach where the nourishment works of 1991 have caused the disappearance of the Posidonia oceanica meadows and a regression process that will lead to the disappearance of the beach in a few years. To this end, data from bathymetry, georeferenced orthophotos, grain size analysis and swell study have been obtained and analyzed, understanding the importance of the works done to be consistent with the environment in which they were developed, and providing a work process which can ensure the existence of the nourished beach starting from the maintenance of Posidonia oceanica meadows.

Nourishing or polluting : redefining the role of waste in the fashion system

Waste is intrinsic to the fashion system. Fashion is predicated on built-in obsolescence, and as such outmoded garments are rapidly discarded to charity shops or landfill. However, the story of fashion is also one of abundance and extravagance in design ideas. Every season there are new design details – prints, embroidery, embellishments, shapes and textures. This excess of ideas is in itself another form of waste, albeit one that is culturally nourishing. The grave of a fashion garment may also be the grave of a season’s research and creativity. This paper compares the tangible waste of the industry with its intangible waste, namely fashion’s creativity and cultural excess. Fashion’s excess and abundance of trends and ideas makes any move to curb the environmental impact difficult. For all practitioners of fashion – whether designers or consumers – the waste and excess inherent in the fashion system is a difficult ethical terrain to negotiate. However, inverting the wasteful phases of the production cycle can help reframe waste from pollution to a source of nourishment for future practice. While creative excesses of designers may be ‘wasted’ after a season, fashion styles and tropes are recycled and reinvented, with the once passé styles and design ideas from previous years revalorized and returned into the fashion system. Similarly, material garments acquire new value through entering or re-entering the second hand or vintage markets. Design processes can utilise pre or post-consumer textile waste, or eliminate waste through design. In these processes, waste becomes the primary source of nourishment for future fashion cycles.

Early Childhood Caries and a Community Trial of its Prevention in Tehran, Iran

Varhaislapsuuden karies ja sen ehkäisy kehittyvän terveydenhuollon maassa Varhaislapsuuden karies on merkittävä kansanterveysongelma varsinkin lapsirikkaissa maissa ja väestöissä. Karieksen hoitaminen vie paljon voimavaroja ja aiheuttaa mittavia taloudellisia seuraamuksia. Karies voi ilmaantua lapselle jo vauvaikäisenä, pian ensimmäisten maitohampaiden puhjettua suuhun. Alle 3-vuotiaiden karieksesta on kuitenkin niukasti tilastotietoja. Maailman terveysjärjestökin suosittaa tietojen keräämistä vasta 3-vuotiaiden ikäryhmästä. Heistä kariesta sairastaa Suomessa 16 %, Yhdysvalloissa 25 %, Englannissa 30 %, Iranissa 46 % ja Saudi-Arabiassa 61 %. Tämä väitöstutkimus selvitti karieksen esiintymistä ja sen vaaratekijöitä 1─3-vuotiailla Teheranissa. Lisäksi tutkimus arvioi perusterveydenhuoltoon sisällytetyn karieksen ehkäisyn tuloksellisuutta. Tutkimuskohteiksi arvottiin Teheranista 18 neuvolaa. Jokaisessa oltiin 4 päivää, jolloin kaikkia rokotuksiin tulleita 1─3-vuotiaita äiteineen pyydettiin osallistumaan tutkimukseen. Kahta lukuun ottamatta kaikki äidit suostuivat, ja aineistoon tuli kaikkiaan 504 lasta äiteineen. Kaikki 1-vuotiaat, 242 lasta äiteineen, valittiin karieksen ehkäisykokeiluun. Sitä varten neuvolat jaettiin kolmeen ryhmään, joista kaksi (A ja B) oli koeryhmiä ja yksi (C) oli vertailuryhmä. Tutkimus alkoi äidin haastattelulla. Siinä selvitettiin perheen koulutus- ja tulotaso sekä lapsen ruokinnasta imetyksen kesto, yösyötöt ja päiväaikaan nautitut makeat. Vielä kysyttiin lapsen ja äidin suuhygieniatavoista ja äidin kokemuksista lapsen suun puhdistamisessa. Sitten hammaslääkäri tutki lapsen suun ja kirjasi karieksen ja hammasplakin esiintymät. Suun tutkimuksen jälkeen äiti ja lapsi siirtyivät rokotushuoneeseen. Koeryhmissä (A ja B) äidit saivat terveydenhoitajalta suunterveyttä koskevan esitteen ja kehotuksen lukea se huolellisesti. Lisäksi ryhmässä A terveydenhoitaja kertoi suun ja hampaiden terveydenhoidosta saman esitteen avulla, ja neuvolan henkilökunta muistutti suunhoidon tärkeydestä puhelimitse kahdesti seuraavan puolen vuoden kuluessa. Vertailuryhmässä äideille ei annettu suunhoidon ohjeita. Kaikissa ryhmissä äitejä muistutettiin seuraavan rokotuskerran ajankohdasta, muttei mainittu tulevaa toista hammastarkastusta. Varhaislapsuuden kariesta sairasti ikäryhmästä riippuen 3─26 % tutkituista 1─3-vuotiaista, ja 65─76 %:lla oli hammasplakkia. Äideistä 68 % harjasi hampaansa päivittäin ja 39 % puhdisti lapsensa suun päivittäin. Mitä useammin äiti harjasi omat hampaansa, sitä paremmin hän huolehti lapsen suun puhtaudesta. Rintaruokinta oli yleistä eikä lisännyt kariesvaaraa. Yöllä pullomaitoa saavilla karies oli 5 kertaa yleisempää kuin muilla. Neuvolassa saatu ohjeistus ehkäisi selvästi karieksen syntyä puolen vuoden kokeessa.

Morphobiometric and molecular characterization of Bursaphelenchus Fuchs, 1937 (Nematoda: Aphelenchoididae) species associated with Pinus pinaster Ainton in Portugal

Abstract - The genus Bursaphelenchus comprises almost 100 species mainly from the northern hemisphere, with conifers as the most important hosts. Among the various nematode species, the pine wood nematode (PWN), Bursaphelenchus xylophilus, is the casual agent of pine wilt disease (PWD), and the most important forest pest for pines worldwide, classified as an A1 quarantine organism within the European Union. In 1999 this nematode was detected for the first time in Portugal and Europa associated with maritime pine, Pinus pinaster. Following detection, a national program denominated "Programa Nacional de Luta contra o Nemátodo da Madeira do Pinheiro" (PROLUNP) was created to, among other objectives, determine the distribution of the PWN and its associated vector(s) and host(s), and therefore intensive surveys covering the entire country were conducted with thousands of wood samples and suspected insects being analyzed. This thesis presents the listing, distribution, frequency and the insects associated with Bursaphelenchus species found associated with maritime pine in Portugal, identifying and characterizing the various species by morphological, biometrical and molecular biology (ITS-RFLP and rDNA sequencing analysis) techniques. To achieve the objectives, a total of 4813 maritime pine wood samples and 3294 insects from 22 species and six families were individually analyzed. A total of nine Bursaphelenchus species were found, namely: B. antoniae, B. hellenicus, B. leoni, B. mucronatus, B. pinasteri, B. sexdentati, B. teratospicularis, B. tusciae and B. xylophilus, all of them (with the exception of B. xylophilus) being new records for Portugal. Some of the species appear to have a widespread distribution, such as B. leoni, B. teratospicularis and B. tusciae while others were very rarely found and apparently have a localized distribution range within the country, namely B. antoniae and B. mucronatus. The majority of the species is characteristic of the Mediterranean region and can also be found in countries such as Spain, Italy and Greece, reflecting the affinity of our fauna with those locations. The association of B. hellenicus and B. tusciae with maritime pine is here reported for the first time. Six of the Bursaphelenchus species were also found associated with insects, mainly from the family Scolytidae (Coleoptera). Some of these interactions were described for the first time, namely: B. hellenicus with both Ips sexdentatus and Hylurgus ligniperda, B. sexdentati with both H. ligniperda and Orthotomicus erosus and B. tusciae with H. ligniperda. The exclusive association of B. xylophilus with the cerambycid Monochamus galloprovincialis was also confirmed. The nematode's dauer juveniles were usually found in low numbers in the insect vectors (ca 10-100 per insect), although for B. xylophilus a few thousand specimens per insect were sometimes found. The location of the dauer juveniles differed according to the species, although they were more common under the elytra and wings of the adult insects. A species new to science was detected and formally described as B. antoniae, associated with Hylobius sp. (Coleoptera; Curculionidae) beetles. Morphologically, this new species is very similar to B. hylobianum, although it's distinct ITS-RFLP molecular pattern (with only the enzyme Haelll producing comparable restriction bands) and the failure of hybridization supported the two species as distinct entities. Additional phylogenetic analysis of the 18S rDNA sequence further supported the taxonomical proximity of B. antoniae with B. hylobianum. Concerning the PWN, detailed studies on the development and morphology of B. xylophilus were conducted, and comparative measurements of field-collected and laboratory-maintained populations demonstrated that nematodes from the second group displayed larger size in all morphometric parameters, which could derive from more adequate conditions of nourishment and/or temperature. Taxonomical studies on the development stages of B. xylophilus confirmed the existence of four propagative juvenile stages (J1,J2,J3 and J4), an adult stage with both sexes and two dispersal stages (jIII e jIV), with the measurements of the gonad length allowing the separation of the propagative stages. It is hoped that the acquired knowledge will be useful on future surveys of nematodes of the Bursaphelenchus genus collected from either wood material or insect vectors, and facilitate the correct distinction and identification of the various species which are now known to occur. ### Resumo - 0 género Bursaphelenchus compreende quase 100 espécies, distribuídas sobretudo nos países do hemisfério norte do globo terrestre. Embora algumas espécies já tenham sido detectadas em plantas herbáceas, os hospedeiros vegetais mais comuns deste género são as coníferas, particularmente pinheiros. 0 nemátode da madeira do pinheiro (NMP), Bursaphelenchus xylophilus, é considerado a espécie mais importante deste género uma vez que é o agente causal da doença da murchidão dos pinheiros ("pine wilt disease"). Originário dos Estados Unidos, onde não causa grande impacte, o NMP foi introduzido em alguns países da Ásia (China, Japão, Coreia e Taiwan) e mais recentemente na Europa (Portugal). Nestas regiões é responsável pela destruição de milhares de hectares de coníferas, assumindo uma elevada importância económica. Em Portugal, depois da sua detecção em 1999, associado a Pinus pinaster, foi implementado um programa nacional "Programa Nacional de Luta contra o Nemátodo da Madeira do Pinheiro" (PROLUNP) que permitiu determinar a área afectada pela praga (a sul do rio Tejo, península de Setúbal) bem como definir e implementar estratégias de controlo e prevenção da disseminação do NMP a outras zonas de Portugal. Recentemente, em Junho de 2008, foi confirmada a presença de B. xylophilus em outras regiões de Portugal levando as autoridades oficiais a definir todo o território continental como zona afectada e de restrição. As prospecções intensivas realizadas nos últimos anos incluíram a recolha e análise de milhares de amostras de madeira de pinheiro bem como de insectos associados ao pinheiro bravo conduzindo à identificação de várias espécies de Bursaphelenchus. Assim, os estudos conduzidos neste trabalho tiveram como objectivos efectuar uma caracterização morfológica, biométrica e molecular das espécies associadas a P. pinaster em Portugal bem como a sua distribuição geográfica e abundância. Os estudos biométricos foram realizados com populações extraídas directamente do meio natural. Foi ainda realizada uma pesquisa que permitiu identificar os insectos a que estão associadas essas espécies, os seus possíveis vectores. Foram analisadas no total 4813 amostras de P. pinaster e 3294 insectos (22 espécies pertencentes a seis famílias diferentes). Foram identificadas um total de nove espécies: B. antoniae n. sp., B. hellenicus, B. leoni, B. mucronatus, B. pinasteri, B. sexdentati, B. teratospicularis, B. tusciae e B. xylophilus. Foram realizados estudos morfológicos e biométricos de todas as espécies com excepção de B. mucronatus; o reduzido número de exemplares encontrados em apenas uma amostra foram utilizados para efectuar o diagnóstico molecular desta espécie (ITS-RFLP). Apesar de ter havido, sempre que possível, a confirmação molecular, na maioria dos casos a caracterização morfológica e biométrica permitiu a correcta identificação das espécies. Contudo, foi imprescindível a análise molecular em algumas amostras, nomeadamente para a identificação de B. xylophilus e B. sexdentati; dada a grande semelhança entre B. xylophilus e B. mucronatus e tendo sido encontradas algumas populações de B. xylophilus que possuíam fêmeas com cauda mucronada, foi necessária a realização da confirmação molecular. Com excepção de B. xylophilus, todas as outras espécies foram reportadas pela primeira vez em Portugal. Juntamente com B. xylophilus, B. pinasteri foi a espécie encontrada nas amostras de madeira de pinheiro com maior frequência. Algumas destas espécies como B. leoni, B. teratospicularis e B. tusciae foram reportadas em diferentes localidades do norte, centro e sul de Portugal, apresentando uma vasta distribuição geográfica; este resultado está em consonância com a forte associação destas espécies a climas mediterrânicos tal como acontece em Espanha, França, Itália e Grécia. Em oposição, espécies como B. antoniae e B. mucronatus foram encontradas apenas numa ocasião na região centro (Leiria) e norte (Figueira da Foz) do país, respectivamente. Bursaphelenchus mucronatus é igualmente pouco frequente em Espanha onde ocorre sobretudo na região norte, na Galiza. Esta espécie preferirá climas mais frios, ocorrendo com uma maior frequência nas regiões de latitude norte; esta análise é corroborada pela presença constante em países como Alemanha, Finlândia, França, Noruega, Rússia e Suécia. A nível mundial são descritas neste trabalho pela primeira vez as associações das espécies B. hellenicus e B. tusciae ao hospedeiro vegetal P. pinaster.

Dental knowledge and attitude toward school dental-health programs among parents of kindergarten children in Winterthur.

The current study investigated the attitudes and knowledge regarding diet and oral hygiene of parents with kindergarten children. The parents' statements were evaluated in terms of their socioeconomic background and were compared with the annual clinical examination of the children. The objective of the study was to assess the effectiveness of the school dental-health program and adapt it to today's societal needs. Of those who participated in the interview, 61% were Swiss, 16% were from former Yugoslavia or Turkey, and 12% each from the EU or other countries. Of the children examined, 39% already had caries, and 18% of those showed more than two lesions. The parents' knowledge correlated with the severity of the child's caries as well as with the parents' income, country of origin, and education. There was a correlation between the child's dental decay and lower income, as well as lower education and non-Swiss nationality of the parents. Parents with higher income and better education more often participated in the preschool's preventive program. Parents from former Yugoslavia or Turkey participated less frequently than parents from other countries. The study demonstrated that parents who especially needed instruction and prophylaxis are contacted too late or not at all through the dental-health program at kindergarten and that new approaches to prevention should be implemented to more effectively reach the parents.
