RESUMO

Diabetic foot is a severe complication of diabetes, with serious consequences such as amputations and high mortality rates as well as elevated economic costs. To evaluate whether or not nursing staff follow the recommendations of national and international organizations regarding diabetic foot prevention, a cross-sectional and observational descriptive study was carried out using an ad hoc self-administered questionnaire validated by seven experts, with a Cronbach's alpha of 0.731. Of the total 164 participants, 157 met the inclusion criteria. Findings showed that 96.58% asked their patients to remove their footwear, 78.34% performed thorough examinations, and 80.25% assessed the risk of developing diabetic foot. Participants educated their patients in self-care and evaluated skills related to diabetic foot control either frequently (84.07%) or very frequently (62.42%), and only 19.11% of them carried out group activity workshops. Significant statistical differences were found in the performance of activities in the groups by participant age intervals, whether working in primary health care or a hospital, having specific training, and the participant's DM patient ratio. We obtained high percentages of compliance in the assessed activities in comparison to other studies. Nevertheless, we believe it is necessary to encourage screening in specialized care, skills testing, and the implementation of educational group activities and workshops.

RESUMO

Entrepreneurship has undoubted social value as it contributes to socio-economic development of the context where entrepreneurship takes place. When the entrepreneurial activity is undertaken among especially vulnerable groups in the labor market, the multiplying effect of this value is made explicit in society, in general, and in the collective of people with disabilities (PWDs), in particular. The objective of this research study is to explore under which conditions this happens through the analysis not only of the relationship between the competencies that PWDs attribute to themselves and their development of the entrepreneurial activity but also of that between entrepreneurship and certain conditions that potentially create value by increasing the autonomy among this collective. A quantitative methodology based on the analysis of the survey carried out on a sample of 224 entrepreneurs with physical, sensory, or organic disabilities throughout Spain has been used. According to the results, entrepreneurs with disabilities (EWDs) have a higher self-evaluation competency. Furthermore, significant results concerning the link between the form of autonomous cohabitation of this collective and entrepreneurship have been obtained.

RESUMO

INTRODUCTION: Data regarding real-world impact on cancer clinical research during COVID-19 are scarce. We analysed the impact of the COVID-19 pandemic on the conduct of paediatric cancer phase I-II trials in Europe through the experience of the Innovative Therapies for Children with Cancer (ITCC). METHODS: A survey was sent to all ITCC-accredited early-phase clinical trial hospitals including questions about impact on staff activities, recruitment, patient care, supply of investigational products and legal aspects, between 1st March and 30th April 2020. RESULTS: Thirty-one of 53 hospitals from 12 countries participated. Challenges reported included staff constraints (30% drop), reduction in planned monitoring activity (67% drop of site initiation visits and 64% of monitoring visits) and patient recruitment (61% drop compared with that in 2019). The percentage of phase I, phase II trials and molecular platforms closing to recruitment in at least one site was 48.5%, 61.3% and 64.3%, respectively. In addition, 26% of sites had restrictions on performing trial assessments because of local contingency plans. Almost half of the units suffered impact upon pending contracts. Most hospitals (65%) are planning on improving organisational and structural changes. CONCLUSION: The study reveals a profound disruption of paediatric cancer early-phase clinical research due to the COVID-19 pandemic across Europe. Reported difficulties affected both patient care and monitoring activity. Efforts should be made to reallocate resources to avoid lost opportunities for patients and to allow the continued advancement of oncology research. Identified adaptations to clinical trial procedures may be integrated to increase preparedness of clinical research to futures crises.

RESUMO

Methicillin-resistant Staphylococcus aureus (MRSA) is a prevalent nosocomial pathogen, causing a wide range of diseases. The increased frequency of MRSA isolates in hospitals and the emergence of vancomycin resistance have sparked the search for new control strategies. This study aimed to characterize sixty-seven MRSA isolates collected from both infected patients and asymptomatic carriers in a Spanish hospital. RAPD-PCR allowed the identification of six genetic patterns. We also investigated the presence of genes involved in producing adhesins, toxins and the capsule; the biofilm; and antimicrobial resistance. A notable percentage of the isolates carried virulence genes and showed medium-high ability to form biofilms. Next, we assessed the strains' susceptibility to two phages (phiIPLA-C1C and phiIPLA-RODI) and one endolysin (LysRODI). All strains were resistant to phiIPLA-C1C, and most (70.2%) were susceptible to phiIPLA-RODI. Regarding LysRODI, all strains displayed susceptibility, although to varying degrees. There was a correlation between endolysin susceptibility and the random amplification of polymorphic DNA (RAPD) profile or the presence of some virulence genes (fnbA, eta, etb, PVL and czr), but that was not observed with biofilm-forming ability, strain origin or phage sensitivity. Taken together, these findings can help to explain the factors influencing endolysin effectiveness, which will contribute to the development of efficient therapies targeting MRSA infections.

RESUMO

INTRODUCTION: Lynch syndrome (LS) and constitutional mismatch repair deficiency (CMMRD) are hereditary cancer syndromes associated with mismatch repair (MMR) deficiency. Tumours show microsatellite instability (MSI), also reported at low levels in non-neoplastic tissues. Our aim was to evaluate the performance of high-sensitivity MSI (hs-MSI) assessment for the identification of LS and CMMRD in non-neoplastic tissues. MATERIALS AND METHODS: Blood DNA samples from 131 individuals were grouped into three cohorts: baseline (22 controls), training (11 CMMRD, 48 LS and 15 controls) and validation (18 CMMRD and 18 controls). Custom next generation sequencing panel and bioinformatics pipeline were used to detect insertions and deletions in microsatellite markers. An hs-MSI score was calculated representing the percentage of unstable markers. RESULTS: The hs-MSI score was significantly higher in CMMRD blood samples when compared with controls in the training cohort (p<0.001). This finding was confirmed in the validation set, reaching 100% specificity and sensitivity. Higher hs-MSI scores were detected in biallelic MSH2 carriers (n=5) compared with MSH6 carriers (n=15). The hs-MSI analysis did not detect a difference between LS and control blood samples (p=0.564). CONCLUSIONS: The hs-MSI approach is a valuable tool for CMMRD diagnosis, especially in suspected patients harbouring MMR variants of unknown significance or non-detected biallelic germline mutations.

RESUMO

Bacterial biofilms constitute a major source of sanitary problems and economic losses in the food industry. Indeed, biofilm removal may require intense mechanical cleaning procedures or very high concentrations of disinfectants or both, which can be damaging to the environment and human health. This study assessed the efficacy of a technique based on spectroscopy in the visible, near-infrared, and short-wavelength infrared range for the quick detection of biofilms formed on polystyrene by the pathogenic bacterium Staphylococcus aureus. To do that, biofilms corresponding to three S. aureus strains, which differed in biofilm-forming ability and composition of the extracellular matrix, were allowed to develop for 5 or 24 h, representing an active formation stage and mature biofilms, respectively. Spectral analysis of the samples, corresponding to three biological replicates of each condition, was then performed by using a portable device. The results of these experiments showed that partial least-squares discriminant analysis of the spectral profile could discriminate between surfaces containing attached bacterial biomass and noninoculated ones. In this model, the two first principal components accounted for 39 and 19% of the variance and the estimated error rate stabilized after four components. Cross-validation accuracy of this assessment was 100%. This work lays the foundation for subsequent development of a spectroscopy-based protocol that allows biofilm detection on food industrial surfaces.

RESUMO

The objective of this study was to assess how disease burden caused by chronic conditions is related to mortality (predictive validity) and other health outcomes (convergent validity). This was studied in 625 community-dwelling adults living in Spain aged 65 years and older. Disease burden was measured with the Disease Burden Morbidity Assessment (DBMA). The association with 5-year mortality was assessed using a Cox model and Kaplan-Meier curves. For convergent validity, mean age, sex ratio, patient-centered outcomes and healthcare utilization were compared for high and low DBMA scores (< 10 vs. ≥ 10). Also, a multivariable linear regression model was used to evaluate the DBMA as a function of these variables. Mean DBMA score in our sample was 7.5. After 5 years, 35 participants had died (5.5%). The Cox model displayed a hazard ratio of 1.07, and the Kaplan-Meier curves showed lower survival for high DBMA scores. Among participants with high DBMA scores, low self-perceived health, disability and female sex were more frequent, and this group showed lower mean scores for quality of life (Personal Wellbeing Index), affect balance (Scale of Positive and Negative Experience) and physical activity (Yale Physical Activity Survey), higher mean age and higher healthcare utilization than persons with low DBMA scores. In the multivariable regression, all variables but age were significantly associated with the DBMA. In conclusion, the DBMA showed satisfactory predictive and convergent validity. In our aging society, it can be applied to better understand and improve care for older persons with multiple chronic conditions.

RESUMO

OBJECTIVES: The foot posture index (FPI) is an observational tool designed to measure the position of the foot. The objective of this study was to establish international reference data for foot posture across childhood, and influence of body mass index (BMI) on paediatric foot posture. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: The dataset comprised 3217 healthy children, aged from 3 to 15 years. Contributing data were acquired from Spain, UK and Australia. INTERVENTIONS: Foot posture was described by means and z-score of the FPI and the height and weight of each subject was measured and the BMI was calculated. RESULTS: The foot posture of 3217 children were reviewed. A pronated (FPI ≥+6) foot posture was found in 960 (29.8%) children, a normal (FPI 0 to +6) foot posture in 1776 (55.2%) and a highly pronated (FPI +10) foot posture was found in 127 children (3.9%) (range -4 to +12 FPI). Less than 11% were found to have a supinated foot type (n=354). Approximately 20% of children were overweight/obese, but correlation between BMI and FPI was weak and inverse (r=-0.066, p<0.01), refuting the relationship between increased body mass and flatfeet. CONCLUSIONS: This study confirms that the 'flat' or pronated foot is the common foot posture of childhood, with FPI score of +4 (3) the average finding. Trend indicated a less flatfoot with age, although non-linear. A wide normal range of foot posture across childhood is confirmed.

RESUMO

Bacteriophages have been proven as effective antimicrobial agents in the treatment of infectious diseases and in other biocontrol applications including food preservation and disinfection. The extensive use of bacteriophages requires improved methodologies for medium- and long-term storage as well as for easy shipping. To this aim, we have determined the stability of four Staphylococcus phages (phiIPLA88, phiIPLA35, phiIPLA-RODI and phiIPLA-C1C) with antimicrobial potential at different temperatures (20°C/25°C, 4°C, -20°C, -80°C, -196°C) and during lyophilization (freeze drying) using several stabilizing additives (disaccharides, glycerol, sorbitol and skim milk). Differences between phages were observed at different temperatures (20°C/25°C, 4°C and -20°C), where phages were less stable. At lower temperatures (-80°C and -196°C), all phages showed good viability after 24 months regardless of the stabilizer. Differences between phages were also observed after lyophilization although the addition of skim milk yielded a dry powder with a stable titer after 24 months. As an alternative to facilitate storage and transportation, phage encapsulation has been also explored. Phage phiIPLA-RODI encapsulated in alginate capsules retained high viability when stored at 4°C for 6 months and at 20°C for 1 month. Moreover, the spray-dryer technique allowed obtaining dry powders containing viable encapsulated phages (phiIPLA-RODI and phiIPLA88) in both skim milk and trehalose for 12 months at 4°C. Storage of phages at 20°C was less effective; in fact, phiIPLA88 was stable for at least 12 months in trehalose but not in skim milk, while phiIPLA-RODI was stable only for 6 months in either stabilizer. These results suggest that encapsulated phages might be a suitable way for shipping phages.

RESUMO

Post-treatment wastewater reuses are diverse. Recreational and environmental restoration uses of reclaimed water (RW) can be potentially harmful to aquatic organisms. In this work the freshwater snail Physa acuta was exposed to RW (100%) and its dilution (RW 50%). A simple laboratory mixture of three emerging pollutants was used to address the complex problem of mixture toxicity of RW. Hence fortified reclaimed water (FRW), obtained by adding fluoxetine (400 µg FLX/L), perfluorooctane sulphonic acid (90 µg PFOS/L) and methylparaben (9 µg MP/L), was tested at two dilution percentages: 100% and 50%. The effects of the laboratory mixture of FLX, PFOS and MP on the test medium were also studied. Long-lasting effects, together with early molecular responses, were assessed. Fecundity (cumulative egg production) over 21 days and the hatching of produced eggs (F1) after another 21-day embryonic exposure were monitored. The gene expression of three genes was analysed after 24 h of exposure: two endocrine-related nuclear receptors (ERR and RXR) and one stress protein gene (Hsp70). This reproduction test, with additional assessments of the F1 recovered eggs' hatching success, showed that both RW and FRW significantly reduced fecundity. F1 hatching was affected only by FRW. The gene expression results showed that the RXR response was strikingly similar to the fecundity response, which suggests that this nuclear receptor is involved in the reproductive pathways of gastropods. ERR remained virtually unaltered. Hsp70 was overexpressed by the laboratory mixture in the test medium, but no effect was observed in the fortification of RW. This opposite effect and lack of response for F1 hatching produced by the laboratory mixture in the test medium highlighted the difficulty of predicting mixture effects. The experimental approach allowed us to test the effects caused by RW on P. acuta at different biological organisation levels. Thus, the combination of molecular biomarkers and ecological relevant endpoints is a good strategy to test complex mixtures like RW as it provides a framework to link mechanisms of action and whole organism effects when it is almost impossible to detect the pollutant(s) that cause toxic effects.

RESUMO

A current focus of research is the development of new tools for removing bacterial biofilms in industrial settings. Bacteriophage-encoded proteins, such as endolysins, virion-associated peptidoglycan hydrolases, and exopolysaccharide depolymerases, have been shown to be efficient against these structures. However, the current screening techniques for the identification of antibiofilm properties of phage-derived proteins have important shortcomings. The aim of this work was to use the rapid, reproducible and accurate technology "real-time cell analyzer" for screening and comparing the antibiofilm ability of four phage-derived compounds, three lytic proteins (LysH5, CHAP-SH3b, and HydH5-SH3b) and one exopolysaccharide depolymerase (Dpo7) against Staphylococcus aureus biofilms, which have been associated with recurrent contamination of food products. The data generated after biofilm treatment allowed for the calculation of different antibiofilm parameters: (1) the minimum biofilm eradicating concentration that removes 50% of the biofilm (ranging from 3.5 ± 1.1 to 6.6 ± 0.5 µM), (2) the lowest concentration needed to observe an antibiofilm effect (∼1.5 µM for all the proteins), and (3) the specific antibiofilm activity and the percentage of biofilm removal that revealed LysH5 as the best antibiofilm compound. Overall, this technology might be used to quickly assess and compare by standardized parameters the disaggregating activity of phage antibiofilm proteins.

RESUMO

Garlic (Allium sativum) and onion (Allium cepa) are being used in the food industry as flavoring but also for their antimicrobial activities. These activities are mainly derived from the organosulfur compounds (OSCs). Propyl propane thiosulfinate (PTS) is an OSC with potential use in the active packaging, but its safety should be guaranteed before being commercialized. The aim of this work was to investigate for the first time the cytotoxicity of PTS as well as its in vitro mutagenic/genotoxic potential using the following battery of genotoxicity tests:(1)the bacterial reverse-mutation assay in S. typhimurium (Ames test, OECD 471, 1997); (2) the micronucleus test (MN, OECD 487, 2016); (3) the mouse lymphoma thymidine-kinase assay (MLA, OECD 476, 2015), and (4) the comet assay (standard and modified with restriction enzymes). The results revealed that PTS was not mutagenic neither in the Ames test nor in MLA. However, genotoxic effects were recorded in the MN test on mammalian cells (L5178YTk+/-cells) after PTS exposure at the highest concentration tested (17.25 µM) without S9, and also its metabolites (+S9, from 20 µM). Moreover, in the comet assay, PTS induced DNA breaks damage in Caco-2 cells at the highest concentration tested (280 µM) but it did not induce oxidative DNA damage.

RESUMO

The PANCOSTABRAX study evaluated the cost-effectiveness of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) in combination with gemcitabine (GEM) versus GEM alone in the treatment of patients with metastatic pancreatic cancer in Spain. Efficacy data were obtained from the MPACT study and were modeled to a lifetime horizon using a Markov model. The analysis was performed from the payer's perspective. Use of resources and key assumptions of the analysis were validated by a panel of oncologists. The addition of nab-paclitaxel to GEM showed higher effectiveness results (0.156 additional quality adjusted life years) at a higher cost (€6,477), resulting in a cost per quality-adjusted life years gained of €41,519. The combination of nab-paclitaxel and GEM has been shown to be an effective and well-tolerated option for the treatment of metastatic pancreatic cancer and, in addition to becoming the new standard of care, could also be considered a cost-effective option.

RESUMO

OBJECTIVES: We carried out a bibliometric study on the scientific publications in relation to atypical antipsychotic drugs (AADs) in Spain. METHODS: We used the EMBASE and MEDLINE databases and we applied some bibliometric indicators of paper production and dispersion (Price's law and Bradford's law, respectively). We also calculated the participation index of the different countries and correlated the bibliometric data with some social and health data (total per capita expenditure on health and gross domestic expenditure on research and development). RESULTS: We collected 656 original papers published between 1988 and 2011. Our study results fulfilled Price's law with scientific production on AADs showing exponential growth (correlation coefficient r = 0.9693, vs. r = 0.9177 after linear adjustment). The most widely studied drugs were risperidone (181 papers), olanzapine (143), clozapine (94), and quetiapine (74). Division into Bradford zones yielded a nucleus occupied by the European Psychiatry and European Neuropsychopharmacology (70 articles). Totally 194 different journals were published, with 5 of the first 10 used journals having an impact factor being greater than 4. CONCLUSION: The publications on AADs in Spain have undergone exponential growth over the studied period, without evidence of reaching a saturation point.

RESUMO

During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching probability (MP) yielded values greater than 0.9998 and 4.32E(-42), respectively. Generally 2-3 SNPs per STR were needed to obtain an equivalent Q value. The MP showed that 24 SNPs were equivalent to the ISAG (International Society for Animal Genetics) minimal recommended set of 12 STRs (MP ∼ 10(-11)). These results provide valuable genetic data that support the consensus SNP panel for bovine genetic identification developed by the Parentage Recording Working Group of ICAR (International Committee for Animal Recording).

RESUMO

BACKGROUND: Living with HIV makes considerable demands on a person in terms of self-management, especially as regards adherence to treatment and coping with adverse side-effects. The online HIV Treatment, Virtual Nursing Assistance and Education (Virus de I'immunodéficience Humaine-Traitement Assistance Virtuelle Infirmière et Enseignement; VIH-TAVIE™) intervention was developed to provide persons living with HIV (PLHIV) with personalized follow-up and real-time support in managing their medication intake on a daily basis. An online randomized controlled trial (RCT) will be conducted to evaluate the efficacy of this intervention primarily in optimizing adherence to combination anti-retroviral therapy (ART) among PLHIV. METHODS/DESIGN: A convenience sample of 232 PLHIV will be split evenly and randomly between an experimental group that will use the web application, and a control group that will be handed a list of websites of interest. Participants must be aged 18 years or older, have been on ART for at least 6 months, and have internet access. The intervention is composed of four interactive computer sessions of 20 to 30 minutes hosted by a virtual nurse who engages the PLHIV in a skills-learning process aimed at improving self-management of medication intake. Adherence constitutes the principal outcome, and is defined as the intake of at least 95% of the prescribed tablets. The following intermediary measures will be assessed: self-efficacy and attitude towards antiretroviral medication, symptom-related discomfort, and emotional support. There will be three measurement times: baseline (T0), after 3 months (T3) and 6 months (T6) of baseline measurement. The principal analyses will focus on comparing the two groups in terms of treatment adherence at the end of follow-up at T6. An intention-to-treat (ITT) analysis will be carried out to evaluate the true value of the intervention in a real context. DISCUSSION: Carrying out this online RCT poses various challenges in terms of recruitment, ethics, and data collection, including participant follow-up over an extended period. Collaboration between researchers from clinical disciplines (nursing, medicine), and experts in behavioral sciences information technology and media will be crucial to the development of innovative solutions to supplying and delivering health services. TRIAL REGISTRATION: CE 11.184 / NCT 01510340.

RESUMO

OBJECTIVE: We have carried out a bibliometric analysis of scientific publications related to attention-deficit hyperactivity disorder (ADHD) and its pharmacological treatment over the period 1980-2005. METHOD: We selected (in EMBASE and MEDLINE databases) documents that contained in their title the descriptors attention deficit hyperactivity disorder, attention deficit disorder, ADHD and ADD. As bibliometric indicators of production and dispersion we applied Price's Law and Bradford's Law, respectively. We also calculated the national participation index (PI) and correlated it with overall PI in biomedical and health sciences, with PI in the discipline of Psychiatry and with the social-health indicators (per capita Gross Domestic Product, number of physicians and total per capita expenditure on health). RESULTS: We obtained 5,269 original documents (2,325 corresponded to pharmacological therapy). Our results indicate fulfilment of Price's Law, since scientific production on ADHD undergoes exponential growth (correlation coefficient r = 0.9859, vs. r = 0.9011 after linear adjustment). The most widely studied drugs are methylphenidate (1,251 documents). Division into Bradford zones yields a nucleus occupied exclusively by the Journal of the American Academy of Child and Adolescent Psychiatry (500 articles). A total of 866 different journals were employed. Twelve of the first 20 used journals have an Impact Factor > 2. The principal producer country is the United States (PI = 44.2). Only four countries, of the 20 major producers in health sciences, surpass their own PI in the field of Psychiatry (Brazil, China, Spain and the United States). The correlation between PI and total number of physicians for each country situates Canada, Australia, the United States and Israel in the top positions. CONCLUSION: Productivity on ADHD has undergone exponential growth in the period 1980-2005, without evidence a saturation point.

RESUMO

BACKGROUND: The current trend in patient care is towards a more humanized and higher-quality healthcare. The objective of the present study was to evaluate the results of implementing a programme of healthcare with a reference nurse who welcomes the patient at hospital admission, visits regularly during hospital stay, and resolves doubts and problems. METHODS: Quasi-experimental study (149 cases and 454 non-tutored controls) in patients admitted for scheduled trauma surgery at the Virgen de las Nieves University Hospital, Granada. Sociodemographic and clinical data were gathered at admission. At 15 days after discharge, patients were administered with an interviewer-administered Zung score and an ad hoc questionnaire on satisfaction with different healthcare aspects during hospital stay and understanding of information received. Bivariate analyses and linear and multivariate logistic regression analyses were performed with a study of confounding variables. RESULTS: For the outcome variable anxiety level non-tutored patients had a B coefficient of 2.64 (p<0,01) in the multivariate linear regression analysis controlling for the other variables in the final model: sex, presence of informal career, professional activity, days of hospital stay and understanding of health information. For the outcome variable inadequate understanding information non-tutored patients showed an odds ratio of 3.48 in the multivariate analysis controlling for educational level and presence of informal career. Satisfaction with he friendliness of health care personnel and with the hospital setting did not significantly difference, although the percentage of dissatisfied patients was higher in the non-tutored group: 15% vs 11% (p= 0.34) and 18% vs 12 % (p= 0.11) respectively. CONCLUSIONS: The implemented continued care programme proved effective for these patients, increasing their understanding of information received and reducing anxiety levels.

RESUMO

UNLABELLED: Assessment of dietetic management is necessary for detection/correction of faults and best care of patients. AIM: Our aim was to evaluate dietetic management and nutritional status of gastroenterologic patients. METHODS: Anthropometric, clinical-nutritional, biochemical, and dietetic parameters were assessed in 110 patients (150 with liver cirrhosis [LC], 30 with inflammatory bowel disease [IBD], and 30 with chronic and skin. In CP, prescribed energy, g and % carbohydrates and lipids were less than ideal and proteins were greater; in cirrhotics, less proteins and a great % of carbohydrates were prescribed; in IBD fewer lipids and more proteins than ideal were prescribed. Cirrhotics usually consumed less fat (g) and more proteins than prescribed, and patients with CP and IBD a greater amount of carbohydrates than prescribed. Cirrhotics consumed more % carbohydrates and < % lipids than ideal; CP patients lipid intake was less and protein intake above ideal and in IBD, carbohydrate intake was greater and lipid intake lower than ideal. CONCLUSIONS: Anthropometric and biochemical parameters were not useful for assessment of these patients. Prescribed diet was too restricted regarding proteins in LC and was inadequate in energy/nutrients in patients with CP. Fewer lipids and more proteins were prescribed in IBD. The inadequacy of prescripted diet, lack of information regarding the person who prescribed it, and lack of constant supervision may cause non-adherence to diet and thus may affect nutritional status.

RESUMO

The WHO’s Healthy Cities Project was set up in 1986 to translate the health for all principles into practice at local level in urban settings. By the end of 1995, all participating cities should have committed themselves to producing City Health Profiles and City Health Plans within four years of joining the project. City Health Profiles are comprehensive reports which provide a description of the health of the city’s population. They use health indicators to define the population’s health in individual cities and present information on the lifestyles, environmental and social factors in the city that affect health. Surveys can be a valuable source of information for Health Profiles. They give local information and may record a range of concerns, including health status, health-related attitudes or experience of health care. But surveys are not the only means of collecting such data. This publication is a resource guide of standard and reliable tools for measuring factors affecting health and can be used to support local ideas and action. The main areas covered include health status and quality of life, health behaviours, health and environment, and health and socioeconomic circumstances. These are the areas that are often underreported in conventional health reporting and yet essential for any serious effort to understand and address health and its determinants in the urban context.
