RESUMO - Este trabalho consiste numa análise sobre a viabilidade económico-financeira do projecto de construção de uma Unidade de Cuidados Continuados Integrados de Longa Duração e Manutenção pela Fundação COI, que pretende ser uma resposta adequada à diversidade de fenómenos que têm origem no envelhecimento populacional, inserindo-se no modelo de prestação de cuidados de saúde e apoio social preconizado pela Rede Nacional de Cuidados Continuados Integrados. Em termos estruturais, numa primeira fase, o trabalho faz uma análise sobre o estado da arte dos cuidados continuado, nomeadamente através da sua conceptualização e enquadramento, focando os aspectos e características da RNCCI, nomeadamente os aspectos relacionados com a sustentabilidade financeira e os desafios futuros que este sector da saúde se confronta. Numa segunda fase, o trabalho apresenta o projecto de investimento alvo do estudo de caso, mediante o enquadramento histórico e caracterização da Fundação COI, sendo descrita especificamente a tipologia de longa duração e manutenção e o projecto em termos da sua estrutura física e humana. Numa terceira fase, o trabalho estuda a racionalidade do projecto de investimento, através da análise económico-financeira. Tendo-se concluído, com a utilização de indicadores de avaliação e decisão de investimentos, que a ULDM, é viável. Deve-se contudo ter em conta que a sua viabilidade é sensível a hipotéticas alterações de cenários, nomeadamente perante diferentes taxas de ocupação ou alteração do modelo de pagamento. ----------------------- ABSTRACT - This paper consists on analyzing the economical and financial viability of a project of Integrated Continuous Cares on Long-Term and Maintenance Unit (LTMU), managed by COI Foundation, that can create a correct social answer on the various aspects and phenomenon’s that have their origin in an aged population. This kind of project belongs in the role model of social and health cares of the National Network of Integrated Continuous Cares (NNICC). In a first stage the paper is focused on the analysis of the state of the present services of the continuous cares in Portugal, more concretely of his conceptualization and social frame, putting under the lights the aspects and characteristics of the NNICC, more closely the parts related to their financial sustainability and the challenges that this health sector faces nowadays. The next stage is about the investment project applied to this case-study, given his social and historical frame and attending to the specific characteristics of the COI Foundation. It’s also describing its specific LTMU typology under the involved physic and human structure. Finally this paper study the investment project rationality trough scientific methods like its economic–financial analysis. The conclusion, using decision and evaluation procedures that lead to financial indicators, is that the LTMU, is viable. However, the viability of the project is sensible to an hypothetical change of scenario, namely with different rates of change of occupation or type of payment.

An understanding of the taxonomic status and vector distribution of anophelines is crucial in controlling malaria. Previous phylogenetic analyses have supported the description of six species of the Neotropical malaria vector Anopheles (Nyssorhynchus) albitarsis s.l. (Diptera: Culicidae): An. albitarsis, Anopheles deaneorum, Anopheles marajoara, Anopheles oryzalimnetes, Anopheles janconnae and An. albitarsis F. To evaluate the taxonomic status of An. albitarsis s.l. mosquitoes collected in various localities in the Colombian Caribbean region, specimens were analyzed using the complete mitochondrial DNA cytochrome oxidase I (COI) gene, the ribosomal DNA (rDNA) internal transcribed spacer 2 (ITS2) region and partial nuclear DNA white gene sequences. Phylogenetic analyses of the COI gene sequences detected a new lineage closely related to An. janconnae in the Caribbean region of Colombia and determined its position relative to the other members of the complex. However, the ITS2 and white gene sequences lacked sufficient resolution to support a new lineage closely related to An. janconnae or the An. janconnae clade. The possible involvement of this new lineage in malaria transmission in Colombia remains unknown, but its phylogenetic closeness to An. janconnae, which has been implicated in local malaria transmission in Brazil, is intriguing.

Sequences of the cytochrome c oxidase subunit I (COI) mitochondrial gene from adults of 22 Culex ( Culex ) species from Argentina and Brazil were employed to assess species identification and to test the usefulness of COI for barcoding using the best close match (BCM) algorithm. A pairwise Kimura two-parameter distance matrix including the mean intra and interspecific distances for 71 COI barcode sequences was constructed. Of the 12 COI lineages recovered in the Neighbour-joining topology, five confirmed recognised morphological species ( Cx. acharistus , Cx. chidesteri , Cx. dolosus , Cx. lygrus and Cx. saltanensis ) with intraspecific divergences lower than 1.75%. Cx. bilineatus is formally resurrected from the synonymy of Cx. dolosus . Cx. maxi , Cx. surinamensis and the Coronator group species included were clustered into an unresolved lineage. The intraspecific distance of Cx. pipiens (3%) was almost twice the interspecific between it and Cx. quinquefasciatus (1.6%). Regarding the BCM criteria, the COI barcode successfully identified 69% of all species. The rest of the sequences, approximately 10%, 18% and 3%, remained as ambiguously, mis and unidentified, respectively. The COI barcode does not contain enough information to distinguish Culex ( Cux. ) species.

Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene. Green lacewings are generalist predators, and the species Chrysoperla externa presents a great potential for use in biological control of agricultural pests due to its high predation and reproduction capacities, as well as its easy mass rearing in the laboratory. The adaptive success of a species is related to genetic variability, so that population genetic studies are extremely important in order to maximize success of the biological control. Thus, the present study used nuclear (Inter Simple Sequence Repeat - ISSR) and mitochondrial (Cytochrome Oxidase I - COI) molecular markers to estimate the genetic variability of 12 populations in the São Paulo State, Brazil, as well as the genetic relationships between populations. High levels of genetic diversity were observed for both markers, and the highest values of genetic diversity appear associated with municipalities that have the greatest areas of native vegetation. There was high haplotype sharing, and there was no correlation between the markers and the geographic distribution of the populations. The AMOVA indicated absence of genetic structure for the COI gene, suggesting that the sampled areas formed a single population unit. However, the great genetic differentiation among populations showed by ISSR demonstrates that these have been under differentiation after their expansion or may also reflect distinct dispersal behavior between males and females.

Although Mar del Plata is the most important city on the Atlantic coast of Argentina, mosquitoes inhabiting such area are almost uncharacterized. To increase our knowledge in their distribution, we sampled specimens of natural populations. After the morphological identification based on taxonomic keys, sequences of DNA from small ribosomal subunit (18S rDNA) and cytochrome c oxidase I (COI) genes were obtained from native species and the phylogenetic analysis of these sequences were done. Fourteen species from the genera Uranotaenia, Culex, Ochlerotatus and Psorophora were found and identified. Our 18S rDNA and COI-based analysis indicates the relationships among groups at the supra-species level in concordance with mosquito taxonomy. The introduction and spread of vectors and diseases carried by them are not known in Mar del Plata, but some of the species found in this study were reported as pathogen vectors.

Five Mbo I (Mbo-A, Mbo-M, Mbo-C(1), Mbo-C(2) and Mbo-C(3)) and Hinf I (Hinf-1 to Hinf-5) patterns were observed in Apis mellifera samples after restriction of a 485 bp fragment of the mitochondrial cytochrome-b (cyt-b) gene. Associating the cyt-b Restriction fragment length polymorphism (RFLP) pattern of each sample to its respective previously established COI-COII (Dra I sites) pattern, five restriction patterns (Mbo-C(1), Mbo-C(2), Mbo-C(3), Hinf-1 and Hinf-4) were observed in samples of maternal origin associated to the evolutionary branch C. No deletions or insertions were observed and the nucleotide substitution rate was estimated at 5.4%. Higher nucleotide diversity was observed among the branch C-haplotypes when compared with A and M lineages. Further studies are needed to confirm if the cyt-b + COI-COII haplotypes help to assign certain phylogeographic patterns to the branch C and to clarify phylogenetic relationships among A. mellifera subspecies.
