Adherence, adaptation and acceptance of elderly chronic heart failure patients to receiving healthcare via telephone-monitoring

Background: Although the potential to reduce hospitalisation and mortality in chronic heart failure (CHF) is well reported, the feasibility of receiving healthcare by structured telephone support or telemonitoring is not. Aims: To determine; adherence, adaptation and acceptability to a national nurse-coordinated telephone-monitoring CHF management strategy. The Chronic Heart Failure Assistance by Telephone Study (CHAT). Methods: Triangulation of descriptive statistics, feedback surveys and qualitative analysis of clinical notes. Cohort comprised of standard care plus intervention (SC + I) participants who completed the first year of the study. Results: 30 GPs (70% rural) randomised to SC + I recruited 79 eligible participants, of whom 60 (76%) completed the full 12 month follow-up period. During this time 3619 calls were made into the CHAT system (mean 45.81 SD ± 79.26, range 0-369), Overall there was an adherence to the study protocol of 65.8% (95% CI 0.54-0.75; p = 0.001) however, of the 60 participants who completed the 12 month follow-up period the adherence was significantly higher at 92.3% (95% CI 0.82-0.97, p ≤ 0.001). Only 3% of this elderly group (mean age 74.7 ±9.3 years) were unable to learn or competently use the technology. Participants rated CHAT with a total acceptability rate of 76.45%. Conclusion: This study shows that elderly CHF patients can adapt quickly, find telephone-monitoring an acceptable part of their healthcare routine, and are able to maintain good adherence for a least 12 months. © 2007.

Does the effect of weight lifting on lymphedema following breast cancer differ by diagnostic method: results from a randomized controlled trial

The lymphedema diagnostic method used in descriptive or intervention studies may influence results found. The purposes of this work were to compare baseline lymphedema prevalence in the physical activity and lymphedema (PAL) trial cohort and to subsequently compare the effect of the weight-lifting intervention on lymphedema, according to four standard diagnostic methods. The PAL trial was a randomized controlled intervention study, involving 295 women who had previously been treated for breast cancer, and evaluated the effect of 12 months of weight lifting on lymphedema status. Four diagnostic methods were used to evaluate lymphedema outcomes: (i) interlimb volume difference through water displacement, (ii) interlimb size difference through sum of arm circumferences, (iii) interlimb impedance ratio using bioimpedance spectroscopy, and (iv) a validated self-report survey. Of the 295 women who participated in the PAL trial, between 22 and 52% were considered to have lymphedema at baseline according to the four diagnostic criteria used. No between-group differences were noted in the proportion of women who had a change in interlimb volume, interlimb size, interlimb ratio, or survey score of ≥5, ≥5, ≥10%, and 1 unit, respectively (cumulative incidence ratio at study end for each measure ranged between 0.6 and 0.8, with confidence intervals spanning 1.0). The variation in proportions of women within the PAL trial considered to have lymphoedema at baseline highlights the potential impact of the diagnostic criteria on population surveillance regarding prevalence of this common morbidity of treatment. Importantly though, progressive weight lifting was shown to be safe for women following breast cancer, even for those at risk or with lymphedema, irrespective of the diagnostic criteria used.

Measuring voluntary dietary change in response to exercise : a focus on dietary fat

Traditional treatments for weight management have focussed on prescribed dietary restriction or regular exercise, or a combination of both. However recidivism for such prescribed treatments remains high, particularly among the overweight and obese. The aim of this thesis was to investigate voluntary dietary changes in the presence of prescribed mixed-mode exercise, conducted over 16 weeks. With the implementation of a single lifestyle change (exercise) it was postulated that the onerous burden of concomitant dietary and exercise compliance would be reduced, leading to voluntary lifestyle changes in such areas as diet. In addition, the failure of exercise as a single weight loss treatment has been reported to be due to compensatory energy intakes, although much of the evidence is from acute exercise studies, necessitating investigation of compensatory intakes during a long-term exercise intervention. Following 16 weeks of moderate intensity exercise, 30 overweight and obese (BMI≥25.00 kg.m-2) men and women showed small but statistically significant decreases in mean dietary fat intakes, without compensatory increases in other macronutrient or total energy intakes. Indeed total energy intakes were significantly lower for men and women following the exercise intervention, due to the decreases in dietary fat intakes. There was a risk that acceptance of the statistical validity of the small changes to dietary fat intakes may have constituted a Type 1 error, with false rejection of the Null hypothesis. Oro-sensory perceptions to changes in fat loads were therefore investigated to determine whether the measured dietary fat changes were detectable by the human palate. The ability to detect small changes in dietary fat provides sensory feedback for self-initiated dietary changes, but lean and overweight participants were unable to distinguish changes to fat loads of similar magnitudes to that measured in the exercise intervention study. Accuracy of the dietary measurement instrument was improved with the effects of random error (day-to-day variability) minimised with the use of a statistically validated 8-day, multiple-pass, 24 hour dietary recall instrument. However systematic error (underreporting) may have masked the magnitude of dietary change, particularly the reduction in dietary fat intakes. A purported biomarker (plasma Apolipoprotein A-IV) (apoA-IV) was subsequently investigated, to monitor systematic error in self-reported dietary intakes. Changes in plasma apoA-IV concentrations were directly correlated with increased and decreased changes to dietary fat intakes, suggesting that this objective marker may be a useful tool to improve the accuracy of dietary measurement in overweight and obese populations, who are susceptible to dietary underreporting.

The effect of implementing a modified early warning scoring (MEWS) system on the adequacy of vital sign documentation

Introduction and objectives Early recognition of deteriorating patients results in better patient outcomes. Modified early warning scores (MEWS) attempt to identify deteriorating patients early so timely interventions can occur thus reducing serious adverse events. We compared frequencies of vital sign recording 24 h post-ICU discharge and 24 h preceding unplanned ICU admission before and after a new observation chart using MEWS and an associated educational programme was implemented into an Australian Tertiary referral hospital in Brisbane. Design Prospective before-and-after intervention study, using a convenience sample of ICU patients who have been discharged to the hospital wards, and in patients with an unplanned ICU admission, during November 2009 (before implementation; n = 69) and February 2010 (after implementation; n = 70). Main outcome measures Any change in a full set or individual vital sign frequency before-and-after the new MEWS observation chart and associated education programme was implemented. A full set of vital signs included Blood pressure (BP), heart rate (HR), temperature (T°), oxygen saturation (SaO2) respiratory rate (RR) and urine output (UO). Results After the MEWS observation chart implementation, we identified a statistically significant increase (210%) in overall frequency of full vital sign set documentation during the first 24 h post-ICU discharge (95% CI 148, 288%, p value <0.001). Frequency of all individual vital sign recordings increased after the MEWS observation chart was implemented. In particular, T° recordings increased by 26% (95% CI 8, 46%, p value = 0.003). An increased frequency of full vital sign set recordings for unplanned ICU admissions were found (44%, 95% CI 2, 102%, p value = 0.035). The only statistically significant improvement in individual vital sign recordings was urine output, demonstrating a 27% increase (95% CI 3, 57%, p value = 0.029). Conclusions The implementation of a new MEWS observation chart plus a supporting educational programme was associated with statistically significant increases in frequency of combined and individual vital sign set recordings during the first 24 h post-ICU discharge. There were no significant changes to frequency of individual vital sign recordings in unplanned admissions to ICU after the MEWS observation chart was implemented, except for urine output. Overall increases in the frequency of full vital sign sets were seen.

Effect of coffee combining green coffee bean constituents with typical roasting products on the Nrf2/ARE pathway in vitro and in vivo

This study investigated Nrf2-activating properties of a coffee blend combining raw coffee bean constituents with 5-O-caffeoylquinic acid (CGA) as a lead component with typical roasting products such as N-methylpyridinium (NMP). In cell culture (HT29) the respective coffee extract (CN-CE) increased nuclear Nrf2 translocation and enhanced the transcription of ARE-dependent genes as exemplified for NAD(P)H:quinone oxidoreductase and glutathione-S-transferase (GST)A1, reflected in the protein level by an increase in GST enzyme activity. In a pilot human intervention study (29 healthy volunteers), daily consumption of 750 mL of CN-coffee for 4 weeks increased Nrf2 transcription in peripheral blood lymphocytes on average. However, the transcriptional response pattern of Nrf2/ARE-dependent genes showed substantial interindividual variations. The presence of SNPs in the Nrf2-promoter, reported recently, as well as the detection of GSTT1*0 (null) genotypes in the study collective strengthens the hypothesis that coffee acts as a modulator of Nrf2-dependent gene response in humans, but genetic polymorphisms play an important role in the individual response pattern.

Coffee and chemoprevention – the genotype decides

In a human intervention study comprising 49 healthy participants, coffee combining natural green coffee bean constituents and dark roast products was identified as a genotype-dependent inducer of Nrf2, significantly affecting Nrf2 gene expression and downstream transcription. Specifically, with 65% of participants showing ≥1.5 fold increase in Nrf2-transcription, the presence of the -651G/A SNP in the Nrf2 gene in conjunction with heterozygosity of the 6/7 AT repeat sequence in the UGT1A1 gene significantly down-regulated coffee-mediated gene expression. Considering the role of the Nrf/ARE pathway in the regulation of antioxidative and chemopreventive phase II efficacy, individual genotype must be considered when examining the potency of bioactive food/food constituents and therapeutic potential.

Use of a photographic food diary method to document dietary intake in people with Parkinson's Disease

Cognitive impairment and physical disability are common in Parkinson’s disease (PD). As a result diet can be difficult to measure. This study aimed to evaluate the use of a photographic dietary record (PhDR) in people with PD. During a 12-week nutrition intervention study, 19 individuals with PD kept 3-day PhDRs on three occasions using point-and-shoot digital cameras. Details on food items present in the PhDRs and those not photographed were collected retrospectively during an interview. Following the first use of the PhDR method, the photographer completed a questionnaire (n=18). In addition, the quality of the PhDRs was evaluated at each time point. The person with PD was the sole photographer in 56% of the cases, with the remainder by the carer or combination of person with PD and the carer. The camera was rated as easy to use by 89%, keeping a PhDR was considered acceptable by 94% and none would rather use a “pen and paper” method. Eighty-three percent felt confident to use the camera again to record intake. Of the photos captured (n=730), 89% were of adequate quality (items visible, in-focus), while only 21% could be used alone (without interview information) to assess intake. Over the study, 22% of eating/drinking occasions were not photographed. PhDRs were considered an easy and acceptable method to measure intake among individuals with PD and their carers. The majority of PhDRs were of adequate quality, however in order to quantify intake the interview was necessary to obtain sufficient detail and capture missing items.

Yhdessä ajattelu ja osallistuminen : Interventiotutkimus yhteistoiminnallisen oppimisen kehittymisestä kahdessa alakoulun pienryhmässä

Participation and social modes of thinking - An intervention study on the development of collaborative learning in two primary school small groups This study explores the thinking together -intervention programme in three primary school classes. The object of the intervention was to teach pupils to use exploratory talk in small group collaboratory learning. Exploratory talk is a type of talk in which joint reasoning is made explicit. Research has shown that exploratory talk can improve mathematics and science learning, argumentative skills and competence in reasoning tests. The object of this study was to investigate the theory of social modes of thinking which the intervention program is based on. I tried to find out how the thinking together -intervention programme suits the Finnish context. Therefore my study is part of an international research project of interventions that have been implemented for example in Great-Britain and in Mexico. One essential drawback in former research made on thinking together -approach is that the nature of participation has not been studied properly. In this study I also examine how the nature of participation develops in small groups. In addition to that I aim to develope a theoretical framework which includes both the perspectives of the social modes of thinking and the nature of participation. The perspective of this study is sociocultural. The research material consists of video recordings of collaborative learning tasks of two small groups. In groups there were pupils of age groups 9 - 11. I study the nature of participation using both qualitative and quantitative methods. Quantitative methods include for example IR-analysis method and counting of turns at talk and words. I also use qualitative content analysis to analyze both the nature of participation and social modes of thinking. As a result of my study I found out that the interaction of the other group was leadership based and in the other group the interaction was without leadership relations. In both groups the participation was quantitatively more symmetrical in the end of the intervention. In the group in which the interaction was leadership based the participation of the pupils was more symmetrical. Exploratory talk was found more in the group without leadership relations, but in both groups the amount of exploratory talk was increased during the intervention. Leadership based interaction was further divided into interaction of alienating and inclusive leadership according to how symmetrical the participation was in the dialogue. Exploratory talk was found only when the leadership was inclusive or the interaction was without leadership relations. The main result of the study was that the exploratory talk was further divided into four subcategories according to the nature of participation. In open and inclusive exploratory talk all group members participated initiatively and their initiatives were responded by others. In closed and uneven exploratory talk some group members couldn't participate properly. Therefore it cannot be said that exploratory talk guarantees symmetrical participation. The nature of participation must be investigated separately.

Nutrition and Nutritional Care of Elderly People in Finnish Nursing Homes and Hospitals

Background: Malnutrition is a common problem for residents of nursing homes and long-term care hospitals. It has a negative influence on elderly residents and patients health and quality of life. Nutritional care seems to have a positive effect on elderly individuals nutritional status and well-being. Studies of Finnish elderly people s nutrition and nutritional care in institutions are scarce. Objectives: The primary aim was to investigate the nutritional status and its associated factors of elderly nursing home residents and long-term care patients in Finland. In particular, to find out, if the nursing or nutritional care factors are associated with the nutritional status, and how do carers and nurses recognize malnutrition. A further aim was to assess the energy and nutrient intake of the residents of dementia wards. A final objective was to find out, if the nutrition training of professionals leads to changes in their knowledge and further translate into better nutrition for the aged residents of dementia wards. Subjects and methods: The residents (n=2114) and patients (n=1043) nutritional status was assessed in all studies using the Mini Nutritional Assessment test (MNA). Information was gathered in a questionnaire on residents and patients daily routines providing nutritional care. Residents energy and nutrient intake (n=23; n=21) in dementia wards were determined over three days by the precise weighing method. Constructive learning theory was the basis for educating the professionals (n=28). A half-structured questionnaire was used to assess professionals learning. Studies I-IV were cross-sectional studies whereas study V was an intervention study. Results: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. According to the MNA, 11% to 57% of the studied elderly people suffered from malnutrition, and 40-89% were at risk of malnutrition, whereas only 0-16% had a good nutritional status. Resident- and patient-related factors such as dementia, impaired ADL (Activities of Daily Living), swallowing difficulties and constipation mainly explained the malnutrition, but also some nutritional care related factors, such as eating less than half of the offered food portion and not receiving snacks were also related to malnutrition. The intake of energy and some nutrients by the residents of dementia wards were lower than those recommended, although the offered food contained enough energy and nutrients. The proportion of residents receiving vitamin D supplementation was low, although there is a recommendation and known benefits for the adequate intake of vitamin D. Nurses recognized malnutrition poorly, only one in four (26.7%) of the actual cases. Keeping and analysing food diaries and reflecting on nutritional issues in small group discussions were effective training methods for professionals. The nutrition education of professionals had a positive impact on the energy and protein intake, BMIs, and the MNA scores of some residents in dementia wards. Conclusions: Malnutrition was common among elderly residents and patients living in nursing homes and hospitals in Finland. Although residents- and patient related factors mainly explained malnutrition, nurses recognized malnutrition poorly and nutritional care possibilities were in minor use. Professionals nutrition education had a positive impact on the nutrition of elderly residents. Further studies describing successful nutritional care and nutrition education of professionals are needed.

Folates in rye: Determination and enhancement by food processing

The average daily intake of folate, one of the B vitamins, falls below recommendations among the Finnish population. Bread and cereals are the main sources of folate, rye being the most significant single source. Processing is a prerequisite for the consumption of whole grain rye; however, little is known about the effect of processing on folates. Moreover, data on the bioavailability of endogenous cereal folates are scarce. The aim of this study was to examine the variation in as well as the effect of fermentation, germination, and thermal processes on folate contents in rye. Bioavailability of endogenous rye folates was investigated in a four-week human intervention study. One of the objectives throughout the work was to optimise and evaluate analytical methods for determining folate contents in cereals. Affinity chromatographic purification followed by high-performance liquid chromatography (HPLC) was a suitable method for analysing cereal products for folate vitamers, and microbiological assay with Lactobacillus rhamnosus reliably quantified the total folate. However, HPLC gave approximately 30% lower results than the microbiological assay. The folate content of rye was high and could be further increased by targeted processing. The vitamer distribution of whole grain rye was characterised by a large proportion of formylated vitamers followed by 5-methyltetrahydrofolate. In sourdough fermentation of rye, the studied yeasts synthesized and lactic acid bacteria mainly depleted folate. Two endogenous bacteria isolated from rye flour were found to produce folate during fermentation. Inclusion of baker s yeast in sourdough fermentation raised the folate level so that the bread could contain more folate than the flour it was made of. Germination markedly increased the folate content of rye, with particularly high folate concentrations in hypocotylar roots. Thermal treatments caused significant folate losses but the preceding germination compensated well for the losses. In the bioavailability study, moderate amounts of endogenous folates in the form of different rye products and orange juice incorporated in the diet improved the folate status among healthy adults. Endogenous folates from rye and orange juice showed similar bioavailability to folic acid from fortified white bread. In brief, it was shown that the folate content of rye can be enhanced manifold by optimising and combining food processing techniques. This offers some practical means to increase the daily intake of folate in a bioavailable form.

Pilottitutkimus apteekkien yksilöllisestä tupakoinninvieroituspalvelusta

Apteekkien yksilöllinen tupakoinninvieroituspalvelu on tupakoinnin lopettamiseen motivoituneille asiakkaille tarkoitettu maksullinen erikoispalvelu, joka sisältää 4–6 tapaamista vieroitusohjaajana toimivan farmaseutin tai proviisorin kanssa. Palvelu sisältää asiakkaalle räätälöityä neuvontaa, henkilökohtaisen vieroitussuunnitelman sekä seurantajakson. Apteekkien yksilöllinen tupakoinninvieroituspalvelu perustuu Isossa-Britanniassa kehitettyyn palvelumalliin, ja sitä on tarjottu suomalaisissa apteekeissa vuodesta 2006. Tämä pro gradu -tutkielma käsittelee apteekkien yksilöllisen tupakoinninvieroituspalvelun pilottitutkimusta, joka toteutettiin Suomen Apteekkariliiton ja Helsingin yliopiston farmasian tiedekunnan sosiaalifarmasian osaston yhteistyönä ja se kuului osana Hengitysliitto Heli ry:n koordinoimaa tupakasta vieroituksen hankekokonaisuutta. Tässä pro gradu -tutkielmassa tarkastellaan pilottitutkimuksessa saadun asiakasaineiston avulla apteekkien yksilöllisen tupakoinninvieroituspalvelumallin toimivuutta, asiakkaiden kokemuksia palvelusta, asiakkaiden onnistumista tupaakoinnin lopettamisessa sekä asiakkaiden kyvykkyyden tunteen kehittymistä palvelun aikana. Tässä interventiotutkimuksessa oli mukana 14 apteekkia, jotka rekrytoivat yhteensä 36 palveluasiakasta. Ennen asiakkaiden rekrytointia apteekit perehdytettiin palvelun tarjoamiseen. Apteekit tiedottivat pilottitutkimuksesta paikallisen terveydenhuollon lääkäreitä ja muita terveydenhuollon ammattilaisia, jotka voivat ohjata asiakkaita palveluun. Sosiaali- ja terveysministeriön pilottitutkimukselle myöntämä rahoitus mahdollisti asiantuntijapalkkion maksamisen apteekeille ja palvelun tarjoamisen asiakkaille ilmaiseksi tai pientä omakustannusosuutta vastaan. Asiakkaiden tupakoimattomana pysymistä sekä kokemuksia tupakoinninvieroituspalvelusta kartoitettiin kyselylomakkeilla, jotka asiakkaat saivat täytettäväkseen palvelun alussa sekä noin 3 kuukauden kohdalla palvelun alkamisesta. Asiakkaiden taustatiedot kerättiin ensimmäisen tapaamisen yhteydessä erillisille taustatietolomakkeille ja palvelun aikana tehtyjä huomioita niille tarkoitetuille kaavakkeille. Ensimmäisen kyselylomakkeen palauttaneista 28 henkilöstä 20 ja toisen kyselylomakkeen palauttaneista 17 henkilöstä 13 oli pysynyt tupakoimattomana (55,6 % ja 36,1 % kaikista asiakkaista). Kaikki tupakoinnin lopettaneet käyttivät jotakin tupakasta vieroituslääkettä. Tupakoinnin lopettaneilla asiakkailla kyvykkyyden tunne oli keskimääräistä parempi sekä palvelun alussa että koko palvelun ajan. Asiakkaat pitivät palvelua tarpeellisena ja apteekin vieroitusohjaajalta saatua tukea tärkeänä. Asiakkaat kokivat myös palvelun saamisen apteekista tärkeäksi. Noin 32 % ensimmäiseen kyselyyn vastanneista ja 41 % toiseen kyselyyn vastanneista oli valmis maksamaan palvelusta. Heidän ilmoittamansa maksuvalmius oli keskimäärin noin 45 euroa (10–100 euroa). Muusta terveydenhuollosta lähetettiin palveluun vain vähän tai ei lainkaan asiakkaita. Tästä syystä apteekit rekrytoivat asiakkaita myös ilman kontaktia muuhun terveydenhuoltoon. Palvelun 36 asiakkaasta noin 36 % oli pysynyt tupakoimattomana 3 kuukauden kohdalla. Verrokkiryhmä jouduttiin jättämään tutkimuksesta pois verrokkihenkilöiden rekrytoinnin epäonnistuttua. Tulos on kuitenkin vertailukelpoinen kansainvälisiin tutkimuksiin, joissa on saatu vastaavanlaisia tuloksia. Apteekkien yksilöllisestä tupakoinninvieroituspalvelusta saattaa olla hyötyä tupakoinnin lopettamisessa siihen motivoituneille henkilöille ja erityisesti henkilöille, jotka käyttävät lisäksi tupakasta vieroituslääkettä. Asiakkaat kokivat palvelun tärkeäksi ja tarpeelliseksi, mutta heikko maksuvalmius asettaa haasteita palvelun tarjoamiselle apteekeissa. Yhteistyömallia muun terveydenhuollon kanssa tulisi kehittää.

Redução do uso e do consumo de açúcar por merendeiras de escolas públicas : ensaio randomizado por conglomerado

O Brasil é um dos maiores consumidores per capita de açúcar e estudos têm mostrado um papel específico do consumo excessivo de açúcar no ganho de peso. Com o aumento do ganho de peso observado em vários países, e também no Brasil, é importante testar quais mensagens, estratégias e propostas de intervenção seriam eficazes na prevenção dessa epidemia. Os dados reportados são referentes a um ensaio randomizado por conglomerado, controlado, conduzido em 20 escolas municipais na cidade metropolitana de Niterói no Estado de Rio de Janeiro, de março a dezembro de 2007, que testou a eficácia de orientações para merendeiras objetivando reduzir a disponibilidade de açúcar e de alimentos fontes de açúcar na alimentação escolar e no consumo delas. A intervenção consistiu em um programa de educação nutricional nas escolas usando mensagens, atividades e material educativo que encorajassem a redução da adição de açúcar na alimentação escolar pelas merendeiras e no consumo delas. A redução da disponibilidade per capita de açúcar pelas escolas foi analisada através de planilhas com dados da utilização dos itens do estoque. O consumo individual das merendeiras foi avaliado através de questionário de freqüência de consumo alimentar. As medidas antropométricas e bioquímicas foram realizadas de acordo com técnicas padronizadas. As escolas de intervenção apresentaram maior redução da disponibilidade per capita de açúcar quando comparadas às escolas controle (-6,0 kg vs. 3,4 kg), mas sem diferença estatisticamente significante. Houve redução no consumo de doces e bebidas açucaradas nas merendeiras dos dois grupos, mas o consumo de açúcar não apresentou diferenças estatisticamente significativas entre eles. Houve redução do consumo de energia total nos dois grupos, mas sem diferença entre eles, e sem modificação dos percentuais de adequação dos macronutrientes em relação ao consumo de energia. Ao final do estudo somente as merendeiras do grupo de intervenção conseguiram manter a perda de peso, porém sem diferença estatisticamente significante. A estratégia de redução da disponibilidade e do consumo de açúcar por merendeiras de escolas públicas não atingiu o principal objetivo de redução de adição de açúcar. Uma análise secundária dos dados avaliou a associação entre a auto-percepção da saúde e da qualidade da alimentação com o excesso de peso e concentração elevada de colesterol sérico das merendeiras na linha de base. As perguntas de auto-percepção foram coletadas por entrevista. Dentre as que consideraram a sua alimentação como saudável, 40% apresentavam colesterol elevado e 61% apresentavam excesso de peso vs. 68% e 74%, respectivamente, para as que consideraram a sua alimentação como não-saudável. Dentre as que consideraram a sua saúde como boa, 41% apresentavam colesterol elevado e 59% apresentavam excesso de peso vs. 71% e 81%, respectivamente, para as que consideraram a sua saúde como ruim. A maioria das mulheres que relatou ter alimentação saudável apresentou maior frequência de consumo de frutas, verduras e legumes, feijão, leite e derivados e menor freqüência de consumo de refrigerante. Conclui-se que perguntas únicas e simples como as utilizadas para a auto-avaliação da saúde podem também ter importância na avaliação da alimentação.

Crioterapia: tecnologia não-invasiva de cuidado da enfermeira obstétrica para alívio da dor em parturientes

Pesquisa piloto de intervenção com dados prospectivos, grupo único de intervenção, cujo desfecho é a medida da dor de mulheres em trabalho de parto. Apresenta como objetivo discutir os efeitos da crioterapia no alívio da dor das parturientes. Como referencial teórico este trabalho apresentou o descrito por Soares e Low, onde se encontra que os mecanismos de ação do gelo para alívio da dor propiciam o decréscimo da transmissão das fibras de dor, a diminuição da excitabilidade nas terminações livres, a redução no metabolismo tecidual aumentando o limiar das fibras de dor e a liberação de endorfinas. Baseou-se ainda nos princípios da desmedicalização e do emprego de tecnologias não-invasivas de cuidado de enfermagem obstétrica conforme descritos por Vargens e Progianti. A pesquisa foi realizada no Centro Obstétrico do Hospital Municipal Maternidade Carmela Dutra, no Rio de Janeiro de abril a agosto de 2011. O gelo foi aplicado, utilizando-se para tal uma bolsa-cinta ajustável à região tóraco-lombar de 36 gestantes. A bolsa/cinta é descartável, de tecido TNT, com abertura na parte superior para introdução de gelo picado envolto em plástico. As aplicações se deram aos cinco centímetros de dilatação do colo uterino; e/ou aos sete centímetros de dilatação do colo uterino; e/ou aos nove centímetros de dilatação uterina, totalizando ao final das três aplicações um tempo de 60 minutos, que corresponde ao somatório de 20 minutos para cada uma. O gelo foi produzido em fôrma exclusiva para o projeto, em freezer da unidade. Os dados referentes à avaliação da dor foram coletados através de entrevista estruturada guiada por formulário previamente elaborado. Os resultados evidenciaram que a crioterapia produziu extinção ou alívio da dor quando aplicada na região tóraco-lombar das parturientes aos cinco, sete ou nove centímetros de dilatação do colo uterino, dando-lhes maiores condições de vivenciar o seu trabalho de parto; produziu um relaxamento geral e local (na região lombar) das parturientes; não interferiu na dinâmica uterina e, não causou dano ao binômio mãe-filho. Concluiu-se que a crioterapia, na forma como descrita no presente estudo, pode ser considerada uma tecnologia não-invasiva de cuidado de enfermagem obstétrica para alivio da dor no trabalho de parto.

Avaliação do impacto de uma intervenção de promoção de frutas e hortaliças sobre o consumo desses alimentos por alunos e professores de escolas públicas

O consumo de frutas e hortaliças (F&H) tem sido incentivado em vários países como medida de prevenção de doenças crônicas não transmissíveis, sendo a escola um espaço privilegiado para a promoção do consumo desses alimentos. Este estudo tem como objetivo avaliar o impacto de uma intervenção de promoção de F&H sobre o consumo desses alimentos por alunos e professores de escolas públicas do município do Rio de Janeiro. Trata-se de estudo de avaliação do tipo antes e depois, realizado com turmas de primeiro ciclo do ensino fundamental em oito unidades públicas municipais situadas em territórios cobertos pela Estratégia da Saúde da Família. No diagnóstico pré-intervenção foram registradas as atividades de promoção da alimentação saudável desenvolvidas nas escolas e o consumo usual de F&H pelos professores. Foram também observados o ambiente escolar e o consumo, pelos alunos, das F&H oferecidas pelo Programa de Alimentação Escolar. A intervenção abarcou um curso de formação para professores e merendeiras sobre promoção da alimentação saudável, com ênfase na promoção de F&H; distribuição de materiais educativos e realização de eventos de mobilização. No diagnóstico pós-intervenção, foram incluídas questões referentes às estratégias da intervenção. Foram criados indicadores de cobertura da atividade e intensidade de exposição à intervenção, de síntese do nível de implementação da intervenção, de adesão à alimentação escolar, aceitação e consumo de F&H pelos alunos e do consumo de F&H pelos professores, e, também, indicadores de variação da aceitação (alunos) e do consumo (alunos e professores) de F&H. As variações observadas foram testadas estatisticamente por meio do teste t-Student pareado (no caso de médias) ou do Qui Quadrado de McNemar (no caso de proporções). A eventual influência do nível de implementação da intervenção sobre a variação do consumo e aceitação de F&H foi examinada por meio de modelos de regressão linear ou logística, dependendo do tipo de desfecho. Foram observados índices altos de aceitação de F&H entre alunos e de consumo de F&H entre alunos e professores no diagnóstico inicial. A intervenção alcançou 52,7% de implementação, tendo sido bem avaliada entre os professores. Nenhuma variação estatisticamente significativa foi observada após a intervenção tanto em relação à aceitação quanto em relação ao consumo de F&H. Foram observados resultados estatisticamente significativos somente para a associação positiva entre o nível de exposição à intervenção e a aceitação de hortaliças pelos alunos. A intervenção proposta alcançou nível intermediário de implementação e os resultados alcançados foram modestos em termos de variação do consumo de F&H por alunos e professores.

Avaliação do impacto de ações para promoção do consumo de frutas e hortaliças no ambiente de trabalho

Objetivo. Avaliar o impacto de ações para promoção do consumo de frutas e hortaliças (FH) no ambiente de trabalho. Método. Estudo de intervenção tipo antes e depois não randomizado com grupo controle histórico, realizado em empresa do ramo da pesquisa científica. A população de estudo consistiu em funcionários que almoçaram no restaurante da empresa nos dias do estudo. No diagnóstico inicial, foram coletados dados de caracterização da empresa estudada e da empresa fornecedora de refeições, caracterização sociodemográfica e consumo de FH pelos indivíduos estudados e sua opinião sobre temas ligados a FH. Foi também realizado grupo focal com formadores de opinião da empresa, a fim de conhecer os determinantes do seu consumo de FH com vistas a subsidiar a construção de estratégias para sua promoção. A intervenção durou oito meses, sendo composta por duas vertentes: ambiental (refeitório da empresa) e educativa (dirigida aos indivíduos). Na primeira, investiu-se na sensibilização do proprietário da empresa concessionária e da responsável técnica para a importância da promoção de FH e em contatos regulares com ela a fim subsidiá-la para a oferta de FH no refeitório. Na segunda, foram realizadas atividades presenciais, distribuídos materiais educativos e desenvolvidas ações de comunicação eletrônica. No diagnóstico final, além do consumo de FH pelos funcionários, foram registrados o nível de exposição dos funcionários à intervenção e suas impressões sobre modificações no restaurante da empresa no tocante à oferta de FH. A análise do impacto da intervenção consistiu no exame da relevância da diferença observada entre proporções ou médias obtidas antes e depois da intervenção. A associação entre intervenção e desfechos foi examinada por meio de modelos de regressão múltipla controlando-se para a situação de consumo inicial e para fatores sociodemográficos dos indivíduos. Resultados. Foram estudados 61 indivíduos. A média de cobertura das atividades e materiais educativos foi de 63,5%, sendo esses avaliados positivamente por 98% dos funcionários. Cerca de 2/3 dos funcionários perceberam mudanças em pelo menos dois aspectos referentes a variedade e aparência das preparações. Do total, 88,6% confiavam na higiene desses alimentos no momento pós intervenção contra 56,9% no momento pré intervenção. Houve um aumento de 53,6g (38%) no consumo de FH no almoço realizado no ambiente de trabalho. Houve também aumento no consumo regular de verduras (de 47,5 para 72,1%), e no número médio de dias de consumo de verduras (de 4,4 para 5,6 dias). Foi observada associação entre aumento do consumo de FH e mudança positiva na confiança em relação à higiene dos alimentos oferecidos crus; aumento do consumo de hortaliças e mudança positiva na confiança em relação à higiene dos alimentos oferecidos crus e nível de exposição à vertente educativa da intervenção; e aumento na média de dias de consumo de legumes e percepção de mudanças positivas na variedade e na apresentação das preparações com FH. Conclusão. Houve um aumento no consumo de FH entre funcionários expostos à intervenção. Seu desenho multicomponente parece ter contribuído para os achados do estudo.
