Monitoring sustainable development in Brazil through a composite index

Sustainable development indicators gained visibility with the United Nations 2030 Agenda and its 17 Sustainable Development Goals. At the same time, two basic problems became relevant: data availability and results communication. The present study aims to deal with both of them by proposing a Sustainable Development (SD) Index for Brazil. Collecting data for such composite index gave the opportunity for facing the data problems: availability and frequency mainly. On the other side, by comparing the Brazilian SD Index in 2001 and 2015, it is possible to show its efficacy in monitoring and easiness in communicating the progress, as well as problems, a country faces in meeting the UN Sustainable Development Goals

Measuring Brazilian Inequality Using the Gender Inequality Index

Gender inequality is a common feature shared by all countries, in different degrees. Its importance is evident in the United Nations 2030 Agenda. The Sustainable Development Goal (SDG) number 5 is mainly dedicated to it. However, for its multidimensional features, different SDGs include it among their targets, the third (health), fourth (education), and tenth (labor) goals in particular. A composite index better describes multiple disparities. In this paper, the Gender Inequality Index (GII), presented in the 2010 Human Development Report, is discussed and then calculated for the Brazilian Federation Units. Its dimensions, health, empowerment, and economic activity cover three crucial dimensions of gender inequality. The GII contributes to evaluate how inequality lowers human development among countries and within a country, as presented in this study. Even though its complex methodology, it is an important tool for policy guidance

Citalopram amplifies the influence of living conditions on mood in depressed patients enrolled in the STAR*D study

Selective serotonin reuptake inhibitors (SSRIs), the most commonly prescribed antidepressant drugs, have a variable and incomplete efficacy. In order to better understand SSRI action, we explored the hypothesis that SSRIs do not affect mood per se but amplify the influence of the living conditions on mood. To this aim, we exploited the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) data set, selected a subpopulation of 591 patients with an overlapping clinical history and analyzed treatment outcome according to dosage −20 or 40 mg per day of citalopram. We found that sociodemographic characteristics affected treatment response in the same direction in the two dose groups, but these effects reached statistical significance only in the 40 mg per day dose group. In the latter, higher improvement rate was associated with having a working employment status (P=0.0219), longer education (P=0.0053), high income (P=0.01) or a private insurance (P=0.0031), and the higher remission rate was associated with having a working employment status (P=0.0326) or longer education (P=0.0484). Moreover, the magnitude of the effect of the sociodemographic characteristics on mood, measured as the percent of patients showing a positive outcome when exposed to favorable living conditions, was much greater—up to 37-fold—in the 40 compared to the 20 mg per day dose group. Overall, our results indicate that citalopram amplifies the influence of the living conditions on mood in a dose-dependent manner. These findings provide a potential explanation for the variable efficacy of SSRIs and might lead to the development of personalized strategies aimed at enhancing their efficacy

Is peer support in group clinics as effective as traditional individual appointments? The first study in patients with Celiac disease

INTRODUCTION: Celiac disease (CD) is common, affecting approximately 1% of the population. The cornerstone of management is a gluten-free diet, with dietetic advice being the key to aiding implementation. The aim of the study was to assess group clinics in comparison with traditional individual appointments. METHODS: Patients with a new diagnosis of CD, confirmed histologically, were prospectively recruited over 18 months in Sheffield, United Kingdom. Patients received either a group clinic or traditional one-to-one appointment, led by a dietitian. Quality-of-life questionnaires were completed at baseline, as well as biochemical parameters being recorded. Patients were followed up at 3 months, where adherence scores were assessed as well as biochemical parameters and quality of life questionnaires being completed. RESULTS: Sixty patients with CD were prospectively recruited and received either an individual (n = 30) or group clinic (n = 30). A statistically significant reduction in tissue transglutaminase was noted following group clinics (mean 58.5, SD 43.4 U/mL vs mean 13.2, SD 5.7 U/mL, P < 0.01). No significant differences in baseline and follow-up biochemical parameters between one-to-one and group clinics were noted. At follow-up, there was no statistically significant difference between mean gluten-free diet adherence scores (mean 3.1, SD 0.4 vs mean 3.1, SD 0.7, P = 0.66) between one-to-one and group clinics. DISCUSSION: This first study assessing group clinics in CD demonstrates they are as effective as traditional one-to-one clinics, with the added benefits of peer support and greater efficiency, with an estimated 54% reduction of dietetic resources

Treatment with fibrates is associated with higher LAL activity in dyslipidemic patients

Lysosomal acid lipase (LAL) is responsible for the hydrolysis of cholesteryl esters (CE) and triglycerides (TG) within the lysosomes; generated cholesterol and free fatty acids (FFA) are released in the cytosol where they can regulate their own synthesis and metabolism. When LAL is not active, as in case of genetic mutations, CE and TG accumulate in the lysosomal compartment, while the lack of release of cholesterol and FFA in the cytosol leads to an upregulation of their synthesis. Thus, LAL plays a central role in the intracellular homeostasis of lipids. Since there are no indications about the effect of different lipid-lowering agents on LAL activity, aim of the study was to address the relationship between LAL activity and the type of lipid-lowering therapy in a cohort of dyslipidemic patients. LAL activity was measured on dried blood spot from 120 patients with hypercholesterolemia or mixed dyslipidemia and was negatively correlated to LDL-cholesterol levels. Among enrolled patients, ninety-one were taking one or more lipid-lowering drugs, as statins, fibrates, ezetimibe and omega-3 polyunsaturated fatty acids. When patients were stratified according to the type of lipid-lowering treatment, i.e. untreated, taking statins or taking fibrates, LAL activity was significantly higher in those with fibrates, even after adjustment for sex, age, BMI, lipid parameters, liver function, metabolic syndrome, diabetes and statin use. In a subset of patients tested after 3 months of treatment with micronized fenofibrate, LAL activity raised by 21%; the increase was negatively correlated with baseline LAL activity. Thus, the use of fibrates is independently associated with higher LAL activity in dyslipidemic patients, suggesting that the positive effects of PPAR-\u3b1 activation on cellular and systemic lipid homeostasis can also include an improved LAL activity

Efficacy of a High-Iron Dietary Intervention in Women with Celiac Disease and Iron Deficiency without Anemia : A Clinical Trial

Background and aim: Iron deficiency without anemia (IDWA) is a common finding in celiac disease (CD) and can also persist in case of good compliance and clinical response to a strict gluten-free diet (GFD). This scenario usually presents in CD women of child-bearing age in whom the imbalance between menstrual iron loss and inadequate iron intake from their diet plays the major role. A recommended approach to this condition is yet to be established. This study aimed to compare, in this subset of patients, the efficacy of a dietary approach consisting of an iron-rich diet against the traditional pharmacological oral-replacement therapy. Material and methods: Between February and December 2016, consecutive CD female patients of child-bearing age as referred to our outpatient center with evidence of IDWA (ferritin &lt;15 ng/mL or 15-20 ng/L with transferrin saturation &lt;15%) were enrolled. After the completion of a 7-day weighed food intake recording to assess the usual iron dietary intake, the patients were randomized in two arms to receive a 12-week iron-rich diet (iron intake &gt;20 mg/die) versus oral iron supplementation with ferrous sulfate (FS) (105 mg/day). Blood tests and dietary assessments were repeated at the end of treatment. The degree of compliance and tolerability to the treatments were assessed every month by means of specific questionnaires and symptoms evaluation. Results: A total of 22 women were enrolled and divided in the diet group (n = 10, age 37 \ub1 8 years) and in the FS group (n = 12, age 38 \ub1 10 years). The food intake records demonstrated an inadequate daily intake of iron in all the enrolled subjects. At the end of the treatments, ferritin levels were higher in the FS group (8.5 (5) versus 34 (30.8), p = 0.002). Compliance and tolerability were similar in both treatment groups (89% versus 87%, p = ns). Conclusions: These findings did not support any equivalent efficacy of an iron-rich diet compared to a FS supplementation in non-anemic iron-deficient women affected by CD. However, the diet appeared a well-tolerated approach, and adequate dietary instructions could effectively increase the daily iron consumption, suggesting a role in the long-term management of IDWA, especially in patients who do not tolerate pharmacological supplementation

Tailoring optical properties and stimulated emission in nanostructured polythiophene

Polythiophenes are the most widely utilized semiconducting polymers in organic electronics, but they are scarcely exploited in photonics due to their high photo-induced absorption caused by interchain polaron pairs, which prevents the establishment of a window of net optical gain. Here we study the photophysics of poly(3-hexylthiophene) configured with different degrees of supramolecular ordering, spin-coated thin films and templated nanowires, and find marked differences in their optical properties. Transient absorption measurements evidence a partially-polarized stimulated emission band in the nanowire samples, in contrast with the photo-induced absorption band observed in spin-coated thin films. In combination with theoretical modeling, our experimental results reveal the origin of the primary photoexcitations dominating the dynamics for different supramolecular ordering, with singlet excitons in the nanostructured samples superseding the presence of polaron pairs, which are present in the disordered films. Our approach demonstrates a viable strategy to direct optical properties through structural control, and the observation of optical gain opens the possibility to the use of polythiophene nanostructures as building blocks of organic optical amplifiers and active photonic devices
