Três alternativas estocásticas para modelar morbimortalidade por doenças respiratórias e cardiovasculares via variáveis atmosféricas

Climate and air pollution, among others, are responsible factors for increase of health vulnerability of the populations that live in urban centers. Climate changes combined with high concentrations of atmospheric pollutants are usually associated with respiratory and cardiovascular diseases. In this sense, the main objective of this research is to model in different ways the climate and health relation, specifically for the children and elderly population which live in São Paulo. Therefore, data of meteorological variables, air pollutants, hospitalizations and deaths from respiratory and cardiovascular diseases a in 11-year period (2000-2010) were used. By using modeling via generalized estimating equations, the relative risk was obtained. By dynamic regression, it was possible to predict the number of deaths through the atmospheric variables and the betabinomial-poisson model was able to estimate the number of deaths and simulate scenarios. The results showed that the risk of hospitalizations due to asthma increases approximately twice for children exposed to high concentrations of particulate matter than children who are not exposed. The risk of death by acute myocardial infarction in elderly increase in 3%, 6%, 4% and 9% due to high concentrations CO, SO2, O3 and PM10, respectively. Regarding the dynamic regression modeling, the results showed that deaths by respiratory diseases can be predicted consistently. The beta-binomial-poisson model was able to reproduce an average number of deaths by heart insufficiency. In the region of Santo Amaro the observed number was 2.462 and the simulated was 2.508, in the Sé region 4.308 were observed and 4.426 simulated, which allowed for the generation of scenarios that may be used as a parameter for decision. Making with these results, it is possible to contribute for methodologies that can improve the understanding of the relation between climate and health and proved support to managers in environmental planning and public health policies.

A influência da perda de peso no perfil inflamatório de mulheres com síndrome dos ovários policísticos

The polycystic ovary syndrome (PCOS) is considered the most common endocrine disorder in reproductive age women, with a prevalence ranging from 15 to 20%. In addition to hormonal and reproductive changes, it is common in PCOS the presence of risk factors for developing cardiovascular disease (CVD) and diabetes mellitus, insulin resistance (IR), visceral obesity, chronic low-grade inflammation and dyslipidemia. Due to the high frequency of obesity associated with PCOS, weight loss is considered as the first-line treatment for the syndrome by improving metabolic and normalizes serum androgens, restoring reproductive function of these patients. Objectives: To evaluate the inflammatory markers and IR in women with PCOS and healthy ovulatory with different nutritional status and how these parameters are displayed after weight loss through caloric restriction in with Down syndrome. Methods: Tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) were assessed in serum samples from 40 women of childbearing age. The volunteers were divided into four groups: Group I (not eutrophic with PCOS, n = 12); Group II (not eutrophic without PCOS, n = 10), Group III (eutrophic with PCOS, n = 08) and Group IV (eutrophic without PCOS, n = 10). The categorization of groups was performed by body mass index (BMI), according to the World Health Organization (WHO) does not eutrophic, overweight and obesity (BMI> 25 kg / m²) and normal weight (BMI <24.9 kg / m²). IR was determined by HOMA-IR index. In the second phase of the study a controlled dietary intervention was performed and inflammatory parameters were evaluated in 21 overweight and obese women with PCOS, before and after weight loss. All patients received a low-calorie diet with reduction of 500 kcal / day of regular consumption with standard concentrations of macronutrients. Results: Phase 1: PCOS patients showed increased levels of CRP (p <0.01) and HOMAIR (p <0.01). When divided by BMI, both not eutrophic group with PCOS (I) as eutrophic with PCOS (III) showed increased levels of CRP (I = 2.35 ± 0,55mg / L and 2.63 ± III = 0,65mg / L; p <0.01) and HOMA-IR (I = 2.16 ± 2.54 and III = 1.07 ± 0.55; p <0.01). There were no differences in TNF-α and IL-6 between groups. Step 2: After the weight loss of 5% of the initial weight was reduced in all of the components of serum assessed inflammatory profile, PCR (154.75 ± 19:33) vs (78.06 ± 8.9) TNF α (10.89 ± 5.09) vs (6:39 ± 1:41) and IL6 (154.75 ± 19:33) vs (78.06 ± 08.09) (p <0:00) in association with improvement some hormonal parameters evaluated. Conclusion: PCOS contributed to the development of chronic inflammation and changes in glucose metabolism by increasing CRP, insulin and HOMA-IR, independent of nutritional status. The weight loss, caloric restriction has improved the inflammatory condition and hormonal status of the evaluated patients.

Perfil sociodemográfico dos idosos nas capitais do Nordeste e a mortalidade por doenças crônico-degenerativas desse segmento populacional em Natal (RN)

Population aging is a global demographic trend. This process is a reality that merits attention and importance in recent years, and cause considerable impact in terms of greater demands on the health sector, social security and special care and attention from families and society as a whole. Thus, in the context of addressing the consequences of demographic transition, population aging is characterized as a major challenge for Brazilian society. Therefore, this study was conducted in two main objectives. In the first article, variables of socioeconomic and demographic contexts were employed to identify multidimensional profiles of elderly residents in the Northeast capitals, from specific indicators from the 2010 Census information Therefore, we used the Grade of Membership Method (GoM), whose design profiles admits that an individual belongs to different degrees of relevance to multiple profiles in order to identify socioeconomic and demographic factors associated with living conditions of the elderly in the Northeastern capitals. The second article examined the possible relationship between mortality from chronic diseases and socio-economic indicators in the elderly population, of the 137 districts in Natal, broken down by ten-year age groups (60 to 69 years, 70-79 years and 80 and over. The microdata from the Mortality Information System (SIM), was used, provided by the Health Secretariat of Christmas, and population information came from the Population Census 2010. The method refers to the Global and Local Index neighborhood logic (LISA) Moran, whose spatial distribution from the choropleth maps allowed us to analyze the mortality of the elderly by neighborhoods, according to socioeconomic and demographic indicators, according to the presence of special significance. In the first article, the results show the identification of three extreme profiles. The Profile 1 which is characterized by median socioeconomic status and contributes 35.5% of elderly residents in the area considered. The profile 2 which brings together seniors with low socioeconomic status characteristics, with a percentage of 24.8% of cases. And the Profile 3 composing elderly with features that reveal better socioeconomic conditions, about 29.7% of the elderly. Overall, the results point to poor living conditions represented by the definition of these profiles, mainly expressed by the results observed in more than half of the northeastern elderly experience a situation of social vulnerability given the large percentage that makes up the Profile 1 and Profile 2, adding 60% of the elderly. In the second article, the results show a higher proportion of elderly concentrated in the neighborhoods of higher socioeconomic status, such as Petrópolis and LagoaSeca. Mortality rates, according to the causes of death and standardized by the empirical Bayesian method were distributed locally as follows: Neoplasms (Reis Santos, New Discovery, New Town, Grass Soft and Ponta Negra); Hypertensive diseases (Blue Lagoon, Potengi, Redinha, Reis Santos, Riverside, Lagoa Nova, Grass Soft, Neópolis and Ponta Negra); Acute Myocardial Infarction (Northeast, Guarapes and grass Soft); Cerebrovascular diseases (Petrópolis and Mother Luiza); Pneumonia (Ribeira, Praia do Meio, New Discovery, Grass Soft and Ponta Negra); Chronic Diseases of the Lower Way Airlines (Igapó, Northeast and Thursdays). The present findings at work may contribute to other studies on the subject and development of specific policies for the elderly.

A crença sobre a morte e o coping religioso-espiritual em pacientes internados com doenças crônicas

The human being is understood as an integral being, complex, which has multiple dimensions: social, biological, psychological, anthropological, spiritual and others. As its biological dimension, the man presents the possibility of physical illness, which means that the body requires care. The sick away from humans in health and safety conditions, approaching them directly from the finitude and vulnerability condition, leading us to contact the major uncertainties of life: suffering of disease and death. Religiosity and spirituality are important coping strategy for human when faced with borderline situations. When people turn to religion to cope with stress is the religious and spiritual coping. The objective of this research was to evaluate the relationship between the views on death and the religious-spiritual coping in patients with chronic diseases hospitalized. The study included ten patients hospitalized for chronic disease complications Medical Clinic Unit of a public hospital in the city of Uberlândia/MG. two psychological scales were used: Scale Religious-Spiritual Coping Brief (CRE-Brief Scale) and Scale Brief Diverse Perspectives of Death and a structured interview (audiogravada) on the subject of death and religious and spiritual coping. The results indicated that 80% of the sample (N = 8) consisted of patients hospitalized due to chronic diseases, while 20% accounted for patients with AIDS complications. Analyzing the results of scale CRE-Brief, it emphasizes the use of strategies of religious and spiritual coping by participants as compared to CRE Total, all study participants had average or high scores for this index, with a low utilization CRE negative and average utilization CRE Positive. Regarding views on death, the results obtained by the Different Perspectives Quick Scale on Death suggest that this sample agrees with the view death as something that is part of the natural cycle of life (M8 - Death as a natural end) and features the prospect of death as uncertainty, mystery and ignorance (M4 - death as Unknown). The correlations between the measures the factors and items of CRE-Bref and dimensions of Short scales on different perspectives of Death notes the prevalence of correlations of M4 dimensions - Death as unknown and M8 - Death as a natural order to the creditor scale soon. In the interview analysis revealed a positive influence of religion/ spirituality on health, from the perspective of the respondent, highlighting the protection promoted by religion. It also noticed the use of prayer as a coping strategy of hospitalization and illness. Regarding the interview about the topic of death, there was a predominance of issues related to "afterlife", "unknown" and "abandonment", which are associated with the visions of death and mystery and death as a natural end. In the interviews there belief clues about death as a terrifying mystery connected, so the unknown and the feeling of fear on the same. The experience of illness can therefore be considered as a source of vulnerability, since it is present personal perception of danger (external) - own illness and possible death, especially in those patients undergoing ICU - and where control is insufficient for the sense of security, since the hospital providing care to the patient are delegated to third parties and patients assume a passive role. This fact is important and relevant to health professionals who deal daily with patients hospitalized for chronic diseases, since the recourse to religion and spirituality as a coping strategy that psychic movement was not constituted in a form of negative distance or even denial of health condition. On the contrary, it refers to a movement in search of comfort and security provided by the religion and spirituality.

Prevalência da síndrome metabólica em receptores de transplante renal de acordo com o gênero e tempo pós-transplante /

Metabolic syndrome (MS) is defined as a set of cardiovascular risk factors including obesity, systemic high blood pressure (SHBP), changes in glucose metabolism and dyslipidemia. The prevalence of MS in renal transplant recipients (RTR) ranges from 15% to 65%, increasing the risk of cardiovascular disease (CVD) and reducing renal allograft survival in the long term. The objectives of this study were to determine the prevalence and frequency of MS in renal transplant patients according to gender and time of transplantation and to evaluate renal function in patients with and without MS. Patients and Methods: Crosssectional study conducted from August 2012 to September 2013 involving 153 renal transplant recipients. MS was defined according to the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III). The sample was divided into two groups: patients with metabolic syndrome (WMS patients) and patients without metabolic syndrome (WoMS patients) and according to gender. The WMS patients were stratified into quartiles according to the renal transplantation period (RTP), and variables related to MS were analyzed for both sexes. Results: MS was diagnosed in 58.1% of the studied population, specifically in MS was found 58.4% of men and 41.6% of women (P ˂ 0.05). The male and female with MS were 48.8 ± 11.6 years old vs. 47.1 ± 12.7 years old and the time of post transplantation was 76.1 ± 76.5 months vs. 84.7 ± 65.4 months, respectively (P >0,05). When we compared the sexes in the WMS group, systolic blood pressure (SBP) was higher in men (137.0 ± 18.1 vs. 128.9 ± 13.6 mmHg, P= 0.029), while the other components of MS did not exhibit significant differences. With respect to renal function, when we compared the sexes in the WMS group, the serum creatinine (sCr) was higher in men (1.73 ± 0.69 vs. 1.31 ± 0.47 mg/dL, P= 0.0012), while the urinary protein/creatinine ratio was higher in women (0.48 ± 0.69 vs. 0.37 ± 0.48 mg/dL, P=0.0150). We found no significant difference in the estimated glomerular filtration rate (eGFR) between WMS and WoMS patients for women and men (50.6 ± 19.1 vs. 50.1 ± 18.3 mL/min/1.73 m², P=0.909). We found a significant positive association between eGFR and HDL-c levels (r=0.3371; P=0.0145) for WMS men. The MS components showed no significant differences in RTP for different interquartile ranges, except for diastolic blood pressure (DBP) in women, where there was a significant variation among the quartiles evaluated (P=0.0009). Conclusion: the prevalence of MS was similar in the different quartiles in both sexes, in relation to time post TX. There was no significant difference in eGFR in patients WMS and WoMS, in both sexes. Concluding that the MS did not vary in relation to time post transplant.

Estudo da composição e das propriedades bioactivas de plantas produtoras de bagas

O consumo de frutas e vegetais tem sido associado à prevenção de várias doenças crónicas, nomeadamente doenças cardiovasculares, diabetes, cancro e outras que envolvam processos inflamatórios. As bagas destacam-se pelo seu elevado conteúdo em polifenóis, cujas propriedades antioxidantes contribuem para a manutenção da saúde humana. O presente trabalho teve como alvo de estudo as diferentes partes morfológicas (bagas e folhas) de espécies produtoras de bagas, nomeadamente Elaeagnus umbellata, a Rubus grandofolius, a Sambucus lancolata, a Vaccinium padifolium e a Vaccinium cylindraceum, tendo em vista a sua valorização como produtos alimentares e/ou nutracêuticos. A caracterização físico-química destas espécies permitiu determinar que o teor total de sólidos solúveis (TSS) das bagas varia de 4,4 a 16,5 °Brix. As bagas demonstraram ser a parte morfológica com teor de humidade mais elevado. A análise do perfil fenólico por HPLC-DAD-ESI/MSn, no modo negativo, dos extractos metanólicos mostrou que as folhas apresentam maior conteúdo de compostos fenólicos, comparativamente às bagas. Os ácidos hidroxicinâmicos (derivados dos ácidos cafeicos, cumárico e ferúlico), os ácidos cafeoilquínicos, bem como os flavonóis-O-glicosilados (derivados da quercetina e canferol) predominam nestas espécies. A análise pelo modo positivo permitiu a identificação de antocianinas glicosiladas (delfinidina, cianidina, petunidina, peonidina e malvidina) nas bagas e folhas jovens da espécie Vaccinium padifolium. Os ensaios in vitro de simulação da digestão gastrointestinal permitiram compreender a sua influência na actividade antioxidante dos extractos. Após a digestão, as folhas continuam a apresentar maior capacidade antioxidante do que as bagas. Adicionalmente, concluiu-se que as enzimas presentes neste processo têm menor influência do que o pH e a força iónica dos sucos digestivos. O estudo do efeito inibitório in vitro dos extractos sobre a actividade de enzimas responsáveis pelo metabolismo dos hidratos de carbono permitiu determinar que os viii Joana Pinto (2016) extractos foram mais eficientes na inibição da actividade da α-glucosidase do que na inibição da actividade da α-amilase.

Prevalência e Sintomatologia Associada a Doenças do Comportamento Alimentar em Adolescentes

As Doenças do Comportamento Alimentar apresentam-se como um problema de saúde proeminente e, como tal, devem ser entendidas como multidimensionais e complexas, que interagem com factores biológicos, psicológicos e sócio-culturais e, que podem ocorrer devido a comportamentos alimentares de carácter patológico e com consequências sérias na qualidade de vida presente e futura. Este trabalho de investigação teve como principal objectivo avaliar a prevalência das Doenças do Comportamento Alimentar numa população não clínica de estudantes, assim como caracterizar o perfil socio-demográfico e familiar dos estudantes e, determinar a relação entre a sintomatologia associada a perturbações do comportamento alimentar e o sexo, idade, IMC, tipo de família, vinculação aos pais e ano de escolaridade dos adolescentes. No intuito de concretizar os objectivos, realizámos um estudo não experimental, transversal e correlacional. A amostra foi constituída por 326 estudantes do 3º Ciclo e do Ensino Secundário da zona centro de Portugal. Foram aplicados um questionário anónimo composto por dados socio-demográficos, antropométricos e clínicos, o Eating Disorder Inventory 2 (EDI 2) e o Questionário de Vinculação ao Pai e à Mãe (QVPM). De acordo com os critérios presentes no DSM-IV-TR não encontramos qualquer caso de Bulimia Nervosa em ambos os sexos. Nas raparigas, constatamos 1,5% de casos prováveis de Anorexia Nervosa tipo Restritivo, 0% de casos prováveis de Anorexia Nervosa tipo Purgativa, 17,3% de casos prováveis de Anorexia Nervosa Restritiva Parcial e 6,1% de casos prováveis de Anorexia Nervosa Purgativa Parcial. Quanto aos rapazes, relatam-se 0,8% de casos prováveis de Anorexia Nervosa tipo Restritivo, 0% de casos prováveis de Anorexia Nervosa tipo Purgativa, 5,2% de situações parciais de Anorexia Nervosa Restritiva e 1,8% de situações parciais de Anorexia Nervosa Purgativa. Foram observadas também, correlações entre a sintomatologia associada a perturbações do comportamento alimentar consoante o sexo, idade, IMC, tipo de família, vinculação aos pais e ano de escolaridade dos inquiridos. Concluímos que todo o sistema familiar e escolar, especialmente pais e professores, devem estar alerta para os sinais manifestados pelos adolescentes no sentido de dar à prevenção um papel fulcral.

O Serviço Social na Unidade de Transplantação Hepática Pediátrica e a Criação da Associação de Crianças e Jovens Transplantados ou com Doenças Hepáticas – HEPATURIX pelo Direito à Saúde

Com a crise financeira que se tem vindo a agudizar, com o agravamento da pobreza e exclusão social, associados a problemas de saúde e à emergência de problemas sociais (como o desemprego e a pobreza) tem assomado uma vaga de iniciativas de movimentos da sociedade civil. São novas formas de organização e resposta a situações específicas de grupos de indivíduos na luta por políticas públicas e direitos sociais tais como o da saúde, da habitação, da educação, do trabalho, entre outras. Nos finais da década de 70, em Portugal, a criação do Serviço Nacional de Saúde intenta o acesso à saúde garantido a todos os cidadãos. Nos anos 80 o Estado limita este direito baseado no princípio da justiça social protegendo os grupos mais desfavorecidos. Institui as taxas moderadoras e define as isenções para alguns doentes crónicos. Perante a desigualdade de direitos que daí advém, no Hospital Pediátrico de Coimbra, a partir dos anos 90, surgem movimentos associativos em prol dos direitos de saúde, criados e dinamizados por Assistentes Sociais, nomeadamente as Associações Acreditar em 1993, a Coração Feliz em 1994, a Associação Nacional de Fibrose Quística em 1996 e já no século XXI a Diabéticos Todo o Terreno em 2004 e a Hepaturix em 2006. A Hepaturix – Associação de Crianças e Jovens Transplantados ou com Doenças Hepáticas – fundada já no século XXI e cuja actividade será descrita neste trabalho, tem vindo a lutar pelos direitos sociais desta população, com a colaboração da Assistente Social que, no Hospital Pediátrico de Coimbra, apoia a Unidade de Transplantação Hepática Pediátrica. Entre outros, a isenção das taxas moderadoras para os doentes transplantados e para os dadores vivos assim como o direito aos transportes nas deslocações para o hospital após o transplante, são direitos sociais alcançados pela Hepaturix através da sensibilização do poder político. A Assistente Social tem sido um pilar neste percurso, sendo mediadora entre a instituição e a associação, em prol do direito destas crianças e jovens. / With the financial crisis that has been worsening, with increased poverty and social exclusion associated with health problems and the emergency of social problems (such as unemployment and poverty) there has been a loomed wave of initiatives for movements from the civil society. These are new ways of organization and response to specific situations of groups of individuals in the strike for public policies and social rights such as health, habitation, education, work, among others. In the late 70s, in Portugal, the creation of the National Health Service intents the access to health care guaranteed to all citizens. In the 80s the government limits this right based on the principle of social justice, protecting the most disadvantaged groups. Establishes user fees and defines the exemptions for some chronically ill. Before the inequality of rights resulted from this, there has been a rising of associative movements for health rights, created and dynamized by Social Workers at the Pediatric Hospital of Coimbra, from the 90s on: "Acreditar" in 1993, "Coração Feliz" in 1994, Associação Nacional da Fibrose Quistica" in 1996 and now, in the XXI century: "Diabéticos Todo o Terreno"in 2004 and "Hepaturix" in 2006. The “Hepaturix” - Association of Transplanted Children and Youth or with Hepatic Diseases - founded in the twenty-first century, whose will be discussed in this work, has been fighting for social rights of this population, with the cooperation of the Social Work who, at the Children’s Hospital of Coimbra, supports the Pediatric Hepatic Transplantation Unit. Among others, the exemption of user fees for transplanted patients and living donors as well as the right to transport at dislocations to the hospital after transplant, are social rights accomplished by Hepaturix, through the awareness of political power. The Social Worker has been a pillar in this journey, being a mediator between the institution and the association on behalf of the rights of these children and youth.

As doenças infeciosas e a história dos antibióticos

O presente trabalho aborda a história das principais doenças que assolaram a Europa desde a época medieval à época contemporânea, incluindo a referência às origens, às manifestações e ao tratamento. É igualmente abordada a questão do isolamento das substâncias ativas nas plantas medicinais e farmacológicas até à descoberta do primeiro antibiótico identificado pelo homem – a penicilina, por Alexandre Fleming – e a sua enorme importância no combate aos micro-organismos.

A fisioterapia no controle e prevenção da disseminação e transmissão das doenças infecciosas

O fisioterapeuta, enquanto profissional de saúde, contacta com uma elevada heterogeneidade de utentes e ambientes e caso sejam negligenciadas as corretas medidas de prevenção e controlo da transmissão e disseminação de doenças infecciosas, o próprio fisioterapeuta além de colocar a sua própria segurança em risco, poderá tornar-se um veículo para a transmissão e disseminação das mesmas entre pacientes, entre pacientes e fisioterapeuta, outros profissionais de saúde e, concomitantemente, levar à contaminação do ambiente e comunidade em geral. Deste modo, é pertinente e urgente que o fisioterapeuta, enquanto profissional de saúde, seja portador de conhecimento sobre os princípios que compreendem as doenças infecciosas e a sua disseminação e as medidas adequadas para o seu controlo e prevenção, de forma a poder contribuir para a prevenção e controlo da infecção como elemento essencial na sua prática profissional.

Potencial fisiológico de sementes de soja enriquecidas com molibdênio no armazenamento e sua influência na atividade de enzimas do metabolismo do nitrogênio

Molybdenum is one of the essential micronutrients for soybeans, acting directly on nitrogen metabolism as enzyme cofactor of nitrogenase. Usually, this nutrient is supplied to the plants through seed treatment or foliar application. The aim of this study was to evaluate the molybdenum effects by foliar in the physiological potential of soybean seeds and verify its interference in the enzyme activities involved in nitrogen metabolism. Soybean seeds of BMX Turbo cultivar were used, produced in Erechim, RS, harvest 2013, from plants treated with the following Mo concentrations: 0; 25; 50 and 75 g ha-1, supplied through two commercial products (Biomol and Molybdate) and stored during 0 and 6 months in uncontrolled conditions. The first experiment was conducted in Seedtes Seed Analysis Laboratory in Pato Branco, PR. The used design was completely randomized in a factorial analysis 4 x 2 x 2 with four replications each. The physiological potential of the seeds was evaluated by the germination test, seedling growth, accelerated aging and emergence on the soil. The second experiment was conducted in a greenhouse, where the seeds derived from treatments with different concentrations of Mo: 0; 25; 50 and 75 g ha-1 supplied through two commercial products (Biomol and Molybdate) were grown in vases. The used design was completely randomized in a factorial analysis 4 x 2 with four replications. Evaluations were performed when the plants reached the R1 phenological stage concerning the nodulation, dry matter of root and shoot of the plants and the determination of the activity of the enzymes glutamine synthetase and glutamate synthetase and the content of total soluble proteins. The data were submitted to variance analysis and when significant they were assessed by Tukey’s test for comparison of products and seed storage and with regression study to the concentrations at 5% probability. Analyses were performed using SISVAR statistical software. The soybean seed storage under uncontrolled conditions affected the seed vigour produced with Mo, regardless of the commercial product used during production. The application of Mo through foliar positively influences the production of soya beans which presented increasing responses in the germination and vigour with the application of Mo above 25 g ha-1 . The enrichment of Mo through foliar did not affect the nodulation of plants of the next generation, however, the use of Mo above 25 g ha-1 provided an increase in the activity of enzymes involved in nitrogen metabolism as well as on the total protein content.

Dickkopf1 (DKK1), metabolismo óseo y enfermedad ateroesclerótica en pacientes con diabetes mellitus tipo 2

Objetivos: La diabetes mellitus tipo 2 (DM2) se asocia a un incremento del riesgo de fracturas y de enfermedades cardiovasculares. Los objetivos de nuestro estudio fueron evaluar los niveles séricos de Dickkopf-1 (DKK1) en una cohorte de pacientes con DM2 y analizar su relación con el metabolismo óseo y la enfermedad ateroesclerótica (EA). Pacientes y métodos: Se estudiaron 126 sujetos: 72 pacientes con DM2 (edad media de 58,2±6 años) y 54 sujetos no diabéticos (edad media de 55,4±7 años). Se midió DKK1 mediante ensayo de inmunoabsorción ligado a enzimas (ELISA, Biomedica Gruppe), se determinó la densidad mineral ósea (DMO) mediante absorciometría dual de rayos X (DXA), se registró la presencia de EA (enfermedad cerebrovascular, enfermedad arterial periférica, cardiopatía isquémica) y se evaluó el grosor de la íntima-media (GIM, ultrasonografía doppler) y la calcificación aórtica (radiología simple). Resultados: No se encontraron diferencias significativas en DKK1 entre diabéticos y no diabéticos. Las concentraciones séricas de DKK1 fueron significativamente mayores en las mujeres de la muestra total (24,3±15,2 vs. 19,6±10,2 pmol/L, p=0,046) y del grupo DM2 (27,5±17,2 vs. 19,8±8,9 pmol/L, p=0,025). Hubo una correlación positiva entre DKK1 y DMO lumbar en la muestra total (r=0,183, p=0,048). Sin embargo, no se encontraron diferencias en función del diagnóstico de osteoporosis o presencia de fracturas vertebrales morfométricas. Los valores de DKK1 fueron significativamente mayores en los pacientes con DM2 y EA (26,4±14,5 pmol/L vs. 19,1±11,6 pmol/L, p=0,026) y también en pacientes con GIM anormal (26,4±15,1 pmol/L vs. 19,8±11,3 pmol/L, p=0,038). En el análisis de la curva ROC para evaluar la utilidad de DKK1 como un marcador de alto riesgo de EA, el área bajo la curva fue de 0,667 (intervalo de confianza -IC- del 95%: 0,538-0,795; p=0,016). Una concentración de 17,3 pmol/L o superior mostró una sensibilidad del 71,4% y una especificidad del 60% para identificar un mayor riesgo de EA. Conclusiones: Los niveles circulantes DKK1 son más altos en los diabéticos con EA y se asocian con un GIM patológico. Por tanto, consideramos que DKK1 puede estar implicado en la enfermedad vascular de los pacientes con DM2.
