Objective To evaluate the implementation of a programme to provide primary care physicians for remote and deprived populations in Brazil. Methods The Mais Médicos (More Doctors) programme was launched in July 2013 with public calls to recruit physicians for priority areas. Other strategies were to increase primary care infrastructure investments and to provide more places at medical schools. We conducted a quasi-experimental, before-and-after evaluation of the implementation of the programme in 1708 municipalities with populations living in extreme poverty and in remote border areas. We compared physician density, primary care coverage and avoidable hospitalizations in municipalities enrolled (n = 1450) and not enrolled (n = 258) in the programme. Data extracted from health information systems and Ministry of Health publications were analysed. Findings By September 2015, 4917 physicians had been added to the 16 524 physicians already in place in municipalities with remote and deprived populations. The number of municipalities with ≥ 1.0 physician per 1000 inhabitants doubled from 163 in 2013 to 348 in 2015. Primary care coverage in enrolled municipalities (based on 3000 inhabitants per primary care team) increased from 77.9% in 2012 to 86.3% in 2015. Avoidable hospitalizations in enrolled municipalities decreased from 44.9% in 2012 to 41.2% in 2015, but remained unchanged in control municipalities. We also documented higher infrastructure investments in enrolled municipalities and an increase in the number of medical school places over the study period. Conclusion Other countries having shortages of physicians could benefit from the lessons of Brazil’s programme towards achieving universal right to health. © 2017, World Health Organization.

Equine semen manipulation during the cooling process reduces sperm viability and fertility in consequence to, among others, membrane lipid peroxidation, because of the high content of polyunsaturated fatty acids, which makes cells highly susceptible to free radicals and reactive oxygen species The objective of the present study was to evaluate the effect of in vitro addition of cysteine in four concentrations (0, 1, 15, and 2.5 mM) for cooling spermatozoa of 12 stallions at 16°C for 36h Evaluated variables were total motility, strength, viability and plasmatic and acrosomal membrane integrity at four different time points (0, 12, 24 and 36 h) With the exception of acrosomal integrity, it was verified a reduction in total motility, strength and plasmatic membrane integrity in all samples, during cooling. In the evaluations at 36 h of cold storage, total motility (mot) and viability (viab) were higher in groups treated with 1 mM (mot:46, 5 ± 6, 1/viab·76, 5 ± 6, 9) and 1.5mM (mot:46, 0 ± 4, 6/viab 76, 9 ± 3, 7) cysteine, respectively, compared to control (mot:35, 5±18, 4/viab 68, 1 ±13, 4) and 2.5mM (mot:39, 7 ± 12, 4/viab·66±l 7, 2) (P<0.05) As for strength (str) and plasmatic membrane integrity (plasm), 1 m M cysteine (str:3.6 ± 0.5/plasm 57.2 ± 9.5) showed better results compared to control (str:3.2±1.1/plasm:54.1±11.8), 1.5mM (str 35±06/plasm·52.2 ±133) and 25mM (str. 3.2 ±1.1/plasm 55.8 ±125) (P<005). Regarding acrosomal membrane integrity, in general, there was no loss of integrity (70.5 ± 10.4, 69.4 ±44, 68.0 ± 7.2 and 703 ± 05), control, 1 mM, 15 mM and 25 mM respectively. The concentration of 1 mM cysteine was more efficient for the protection of sperm cells in the commercial system of passive cooling at 16°C for 36 h, with higher values for total motility, strength, viability and plasmatic membrane integrity.

Systematic Botany | Year: 2017

An unusual new species of Bidens (Asteraceae) from Brazil is described and its placement within the genus is elucidated by phylogenetic analysis of ITS sequences. The new species, described as Bidens campanulata, is distinct in the genus based on its broadly campanulate corolla limb with long lobes, an extremely reduced involucre (shorter than the flower length), and the absence of awns on the pappus. This study presents a taxonomic treatment of the species of Bidens with discoid capitula endemic to the Brazilian Cerrado, including a key to the species, typification, and information on conservation status. © 2017 by the American Society of Plant Taxonomists.

We determine the high-frequency limiting shear viscosity, η∞, in colloidal suspensions of rigid, uniformly porous spheres of radius a as a function of volume fraction φ and (inverse) porosity parameter x. Our study covers the complete fluid-state regime. The flow inside the spheres is modeled by the Debye-Bueche-Brinkman equation using the boundary condition that fluid velocity and stress change continuously across the sphere surfaces. The many-sphere hydrodynamic interactions in concentrated systems are fully accounted for by a precise hydrodynamic multipole method encoded in our HYDROMULTIPOLE program extended to porous particles. A truncated virial expansion is used to derive an accurate and easy-to-use generalized Saitô formula for η∞. The simulation data are used to test the performance of two simplifying effective particle models. The first model describes the effective particle as a nonporous sphere characterized by a single effective radius aeff (x)

We study the high-frequency limiting shear viscosity, η ∞ of colloidal suspensions of uncharged porous particles. An individual particle is modeled as a uniformly porous sphere with the internal solvent flow described by the Debye-Bueche-Brinkman equation. A precise hydrodynamic multipole method with a full account of many-particle hydrodynamic interactions encoded in the hydromultipole program extended to porous particles, is used to calculate η∞ as a function of porosity and concentration. The second-order virial expansion for η∞ is derived, and its range of applicability assessed. The simulation results are used to test the validity of generalized Stokes-Einstein relations between η∞ and various short-time diffusion coefficients, and to quantify the accuracy of a simplifying cell model calculation of η∞ .An easy-to-use generalized Saito formula for η∞ is presented which provides a good description of its porosity and concentration dependence. © 2010 IOP Publishing Ltd.

This paper analyzes whether south-south cooperation is legitimately a recent practice or merely an improved version of previous regional integration processes in Latin America and the Caribbean. The authors reviewed and systematized the historic development of subregional integration processes in Latin America and the Caribbean and focused on health cooperation in the following contexts: the Central American Integration System, the Andean Community of Nations, the Caribbean Community, the Amazon Cooperation Treaty Organization, the Southern Common Market, and the Union of South American Nations. The study concludes that the conceptual and methodologic foundations of south-south cooperation in health were born from and nurtured by the processes of regional integration in Latin America and the Caribbean. This paper posits that regional political and economic integration initiatives bring potential benefits to the health sector and act as an important mechanism to develop south-south cooperation in this domain. The study recommends furthering this type of research to provide information that will allow national and multilateral agencies, or other stakeholders, to formulate and implement better policies for international health cooperation that target reducing inequities and promoting health and wellbeing for all people.

When Judd-Ofelt intensity parameters of polynuclear compounds with asymmetric centers are calculated using the current procedure, the results are inconsistent. The problem arises from the fact that the experimental intensity parameters cannot be determined for each asymmetric polyhedron, and this precludes the individual theoretical adjustment. In this study, we then propose three different methods for calculation of these parameters of polyeuropium systems. The first, named the centroid method, proposes the calculation considering the center of the dimeric system as the half distances between the two europium centers. The second method, called the overlapped polyhedra method, proposes the calculation considering the overlapping of both europium polyhedra, and the last one, the individual polyhedron method, proposes the use of theoretical mean values of charge factors and polarizabilities associated with each europium-ligand atom bond to calculate the intensity parameters. One symmetric polyeuropium system and one asymmetric system were assessed by using the three methods. Among the methods assessed, the one based on the overlapped polyhedra produced more consistent results for the study of both kinds of systems. © 2013 American Chemical Society.

The incidence of type 2 (T2D) diabetes and other chronic conditions associated with insulin resistance is increasing at an alarming rate, underscoring the need for effective and safe therapeutic strategies. Peroxisome-proliferator-activated receptor gamma (PPAR) has emerged as a critical regulator of glucose homeostasis, lipid homeostasis, and vascular inflammation. Currently marketed drugs targeting this receptor, the thiazolidinediones (TZDs), have proven benefits on insulin resistance and hyperglycemia associated with T2D. Unfortunately, they have been associated with long-term unfavorable effects on health, such as weight gain, plasma volume expansion, bone loss, cardiovascular toxicity, and possibly cancer, and these safety concerns have led to reduced interest for many PPAR ligands. However, over the last years, data from human genetic studies, animal models, and studies with ligands have increased our understanding of PPARs actions and provided important insights into how ligand development strategies could be optimized to increase effectiveness and safety of PPAR-based therapies.

This paper aims to discuss some concepts - developed within the Coloniality Studies by a group of thinkers in Latin America - about how Modernity emerged structured as a way to dispose power, knowledge and being, so that a hierarchy between center and periphery, installed in a colonial perspective, organizes our way of dealing with politics, with science and - this is the main focus of this paper - with life. Intervention Bioethics (IB), whose proposal is to politicize in an ethical manner the method of dealing with biotechnoscientific, sanitary, social and environmental conflicts from the Latin American reality, develops a line of research that can accommodate the contributions, as well as the criticisms, from Coloniality Studies, particularly with regard to conceptual frameworks related to the ethical and epistemological theories that support it. Among these conceptual frameworks, this paper deals specifically with the relationship between the utilitarianism accepted by IB through a supportive consequentialism and its interrelations with the idea of Coloniality.

This work presents a numerical study of the relative trajectories of two magnetic particles interacting in a dilute suspension. The suspension is composed of magnetic spherical particles of different radius and density immersed in a Newtonian fluid. The particles settle relative to one another under the action of gravity and, when in close proximity, exert on each other magnetic force and torque due to their permanent magnetization. The equations of motion for both translation and rotation of the particles are solved and particle inertia is included in the calculation. The numerical simulations are based on the direct computations of the hydrodynamic and of the magnetic interactions between the rigid particles in the regime of non-zero Stokes number. A detailed study of the relative trajectories of two magnetic particles in a dilute suspension allows us to explore irreversible interactions that lead to particle aggregation and particle migration induced by the breaking of the time reversibility of the creeping flow due to magnetic effects. The calculation shows that the rotation of the particles produced by magnetic interactions change significantly the dynamics of collisions of magnetic particle. © 2012 Elsevier B.V.
