Health-related Quality Of Life And Self-reported Long-term Conditions: A Population-based Survey
Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)To estimate and compare the effect of self-reported long-term health conditions and sociodemographic factors on perceived health-related quality of life (HRQoL). Methods: A population-based survey of adults (18 to 65 years) living in Brasilia, Brazil, was conducted in 2012. Descriptive and multivariate analyses using a Tobit model were performed with data on sociodemographic variables, self-reported conditions, and the European Quality of Life-5 Dimensions (EQ-5D) health states, providing utility scores (preferred health state) between 0 and 1 for HRQoL estimates. Results: The mean utility of 1,820 adults interviewed (mean age: 38.4612.6 years) was 0.883 (95% confidence interval [95% CI] 0.874-0.892), with 76.2% in the highest utility range (0.8 to 1.0). EQ-5D dimensions with moderate problems were pain/discomfort (33.8%) and anxiety/depression (20.5%). Serious problems were reported by only 0.3% of the sample in the mobility and self-care domain and by 3.1% in the pain/discomfort domain. Multivariate analysis revealed reduced HRQoL in individuals with depression, diabetes, and hypertension. Living in satellite towns (outside the city core), belonging to a lower economic class, or not being formally employed were also associated with decreased HRQoL. Beta coefficients for these impacts ranged from -0.033 (not formally employed) to -0.141 (depression), reflecting the strongest impact. Conclusion: Of the long-term health conditions studied, depression had the greatest impact on HRQoL. Social class, employment status, and place of residence also affected HRQoL.3916268Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) [564831/2010-7]Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
THE USE OF GENETIC MODIFIED MICE AS A MODEL TO STUDY CARDIOVASCULAR DISEASES
This review describes some strategies for the employment of mice in the study of cardiovascular physiology and physiopathology. Among the major advantages of using the mice, we should consider fast reproduction and low maintenance costs. Moreover, the unnumbered possibilities of genetically modification in these animals allow the development of targeted gene mutation, like transgenic mice, characterized by a introduction of a foreign DNA into its genome (knockin), or, more common, the development of knockout mice. These are animals in which a specific gene was disrupted, causing particular characteristics, such as the deficiency of a 2A receptor or the absence of the nNOS enzyme. Methodologies and techniques for cardiovascular research on mice are summarized and discussed and some results, about the use of mice in the cardiovascular study, are also showed in this review.Na presente revisão apresentamos dados e elementos sobre o emprego de camundongos no estudo da fisiologia e fisiopatologia cardiovascular. São apontadas as vantagens de seu emprego, como por exemplo, a facilidade de criação e reprodução. Deve se destacar que a possibilidade desses animais serem manipulados por meio da engenharia genética, nos permite obter animais transgênicos, que se caracterizam por manipulação genética visando a introdução de genes de outras espécies, ou, o que é mais comum, a produção de animais knockout. Animais que apresentam deficiência especifica em um gene, não expressando, portanto, determinadas características, como a deficiência do receptor 2A ou a ausência da enzima nNOS. As metodologias e técnicas necessárias para o estudo cardiovascular desses animais são apresentadas e discutidas. São também demonstrados alguns resultados dentre os já obtidos, com o emprego destes animais e uma breve discussão dos mesmos
Pubertal timing in girls and depression: A systematic review
Background: Because the incidence of depression increases after puberty, it is possible that pubertal timing in girls influences the onset of depression. Our objective was to assess the effect of early and late puberty in girls on the incidence of depression. Methods: We systematically searched relevant databases for controlled studies that assessed the impact of pubertal timing in girls on the incidence of depression or depressive symptoms. The last search was completed in August 2013. Two authors selected the studies, extracted the data, and assessed the quality of the evidence. Meta-analyses of the adjusted and unadjusted results were calculated using random effects. Results: Four cohort studies were included (n=8055 participants). Early puberty significantly increased the risk of new cases of depression in the unadjusted meta-analysis (RR=1.33; CI 95%: 1.02, 1.73) but not in the adjusted estimate of two of the included studies (RR=1.48; CI 95%: 0.69, 2.28). For late puberty, no significant associations were found (unadjusted RR=1.28; CI 95%: 0.87, 1.88). Two studies assessed the effect of early puberty on depressive symptoms and found positive associations. The quality of the available evidence was rated as very low. Limitations: The polled results had wide confidence intervals, and the available evidence was of very low quality. Conclusions: The available evidence supports little confidence regarding the impact of pubertal timing on the onset of depression in girls but suggests that early puberty in girls may increase the risk of depression. Further higher quality studies are needed to clarify the association between pubertal timing and the incidence of depression in girls and women
(R)-(-)-carvone and (1R, 4R)-trans-(+)-dihydrocarvone from poiretia latifolia vogel
The essential oils of Poiretia latifolia Vogel, native and cultivated leaves (Samples A and B, respectively) and native flowers (sample C), were obtained by hydrodistillation and analyzed by GC, GC/MS and chiral phase gas chromatography (CPGC). Twenty-four compounds were identified, representing 99.25, 99.26 and 99.23% of the oils, respectively. The major constituents of the oils were the monoterpenes (S)-(-)-limonene (16.05, 27.60, 15.60%, respectively), (1R, 4R)-trans-(+)-dihydrocarvone (18.05, 0.66 and 77.80%, respectively) and (R)-(-)-carvone (61.05, 64.20 and 4.50%, respectively). The essential oils were evaluated against some strains of Gram (+) and Gram (-) bacteria, and yeast, but displayed only modest antimicrobial activity
Profile of Trypanosoma cruzi Infection in a Tropical Medicine Reference Center, Northern Italy
Chagas disease (CD) is endemic in Central and South America, Mexico and even in some areas of the United States. However, cases have been increasingly recorded also in non-endemic countries. The estimated number of infected people in Europe is in a wide range of 14000 to 181000 subjects, mostly resident in Spain, Italy and the United Kingdom
Effect of physical stimuli on hair follicle deposition of clobetasol-loaded Lipid Nanocarriers
Clobetasol propionate (CLO) is a potent glucocorticoid used to treat inflammation-based skin, scalp, and hair disorders. In such conditions, hair follicles (HF) are not only the target site but can also act as drug reservoirs when certain formulations are topically applied. Recently, we have demonstrated nanostructured lipid carriers (NLC) containing CLO presenting epidermal-targeting potential. Here, the focus was evaluating the HF uptake provided by such nanoparticles in comparison to a commercial cream and investigating the influence of different physical stimuli [i.e., infrared (IR) irradiation (with and without metallic nanoparticles-MNP), ultrasound (US) (with and without vibration) and mechanical massage] on their follicular targeting potential. Nanosystems presented sizes around 180 nm (PdI < 0.2) and negative zeta potential. The formulation did not alter skin water loss measurements and was stable for at least 30 days at 5 °C. Nanoparticles released the drug in a sustained fashion for more than 3 days and increased passively about 40 times CLO follicular uptake compared to the commercial cream. Confocal images confirmed the enhanced follicular delivery. On the one hand, NLC application followed by IR for heat generation showed no benefit in terms of HF targeting even at higher temperatures generated by metallic nanoparticle heating. On the other hand, upon US treatment, CLO retention was significantly increased in deeper skin layers. The addition of mechanical vibration to the US treatment led to higher follicular accumulation compared to passive exposure to NLC without stimuli. However, from all evaluated stimuli, manual massage presented the highest follicular targeting potential, driving more than double the amount of CLO into the HF than NLC passive application. In conclusion, NLC showed great potential for delivering CLO to HF, and a simple massage was capable of doubling follicular retention
Gait speed, balance and functional capacity in a sample of community-dwelling older adults
Introduction: Falls in older people is an important public health concern since they are responsible for a high number of hospitalizations, health complications, disability, and death. Gait speed has been identified as a predictor of health state in elderly populations and it is related to falls and functional capacity. The aim of this study was to identify the risk of falling in a sample of Portuguese older adults living in the community and to investigate the associations between gait speed, balance, and functionality. Methods: This was a cross-sectional study. Assessment included gait speed (GS) with 4-meter walk test; balance with the Berg Balance Scale (BBS); functional capacity with the Composite Physical Function Scale (CPF). Descriptive and correlational statistics were performed to analyze data. Results: 46 community-dwelling older adults (32 women; 14 men) aged 77 ± 9 years participated in our study. Mean value for GS was 1.17 ± 0.37 m/s which is normal for this population. For BBS and CPF median was 52 and 19, respectively. BBS results revealed a risk of falling off 43% and functional capacity of our participants was at moderate levels. The study of correlations between variables also showed positive associations between GS and BBS (R = 0.631; p = 0.00) and between GS and CPF (R = 0.605; p = 0.00). Conclusions: Positive associations between GS and balance and between GS and functional capacity highlight the role of GS in the assessment of fall risk and functional capacity since it is a simple and easy test to perform.info:eu-repo/semantics/publishedVersio
Problem-Based Learning in Pharmaceutical Education: A Systematic Review and Meta-Analysis
Objective. To assess the effects of problem-based learning (PBL) on the learning achievements of pharmacy students. Methods. We searched for controlled studies that compared PBL to traditional learning in pharmacy courses (graduate and undergraduate) in the major literature databases up to January 2014. Two independent researchers selected the studies, extracted the data, and assessed the quality of the studies. Meta-analyses of the outcomes were performed using a random effects model. Results. From 1,988 retrieved records, five were included in present review. The studies assessed students' impressions about the PBL method and compared student grades on the midterm and final examinations. PBL students performed better on midterm examinations (odds ratio [OR] = 1.46; confidence interval [IC] 95%: 1.16, 1.89) and final examinations (OR = 1.60; IC 95%: 1.06, 2.43) compared with students in the traditional learning groups. No difference was found between the groups in the subjective evaluations. Conclusion. pharmacy students' knowledge was improved by the PBL method. Pharmaceutical education courses should consider implementing PBL
