Matrix Support in Mental Health: Achievements and Limits in Primary Health Care

Changes in mental health care in the city of Fortaleza (Northeastern Brazil) have a recent historical and political process. Compared to other municipalities of the State of Ceara, which in the early 1990s were already pioneers in the process, Fortaleza has not implemented the changes due to the interests of psychiatric hospitals, of psychiatric outpatient clinics of the public network, and because of the difficulty in managing the new mental health devices and equipment present in Primary Care. In the municipality, the reorganization of mental health actions and services has required that the Primary Care Network faces the challenge of assisting mental health problems with the implementation of Matrix Support. In light of this context, we aimed to evaluate Matrix Support in mental health in Primary Care Units and to identify achievements and limitations in the Primary Care Units with Matrix Support. This study used a qualitative approach and was carried out by means of a case study. We interviewed twelve professionals from the Family Health Teams of four Units with implemented Matrix Support. The analysis of the information reveals that access, decision making, participation and the challenges of implementing Matrix Support are elements that are, in a dialectic way, weak and strong in the reorganization of services and practices. The presence of Matrix Support in Primary Care highlights the proposal of dealing with mental health within the network in the municipality. The process has not ended. Mobilization, awareness-raising and qualification of Primary Care have to be enhanced constantly, but implementation has enabled, to the service and professionals, greater acceptance of mental health in Primary Care.

Family Health Support Centers: challenges and opportunities from the perspective of primary care professionals in the city of Sao Paulo, Brazil

Family Health Support Centers (NASF) were created in Brazil to increase the case-resolution capacity of primary healthcare. Prior to their implementation in the West Side of the city of Sao Paulo, Brazil, a series of workshops were held for primary healthcare professionals to prepare a proposal for such centers. Hermeneutic analysis was used to study the transcribed material. The thematic categories were: role, constitution, and functioning of the NASF, relationship with family health teams, and interdisciplinarity. The participants' expected the NASF to be an empowering device for comprehensiveness of care, intervening in an existing culture of unnecessary referrals while fostering linkage with other levels of care. The participants also expected the NASF to contribute to the discussion on health professionals' training and stimulating reflection with policy-makers on health indicators based exclusively on the number of consultations. These indicators fail to reflect the impact on the services' activities and the quality of care offered to the population in the coverage area.

Family Health Strategy Professionals Facing Medical Social Needs: difficulties and coping strategies

Professionals of Family Health Strategy (FHS) work in communities where there are complex medical social problems. These contexts may lead them to psychological suffering, jeopardizing their care for the users, and creating yet another obstacle to the consolidation of FHS as the primary health care model in Brazil. The study investigated the difficulties and coping strategies reported by health professionals of the FHS teams when they face medical social needs of the communities where they work. Focus groups and semi-structured interviews were carried out with 68 professionals of three primary care units in the city of Sao Paulo (Southeastern Brazil). Drug dealing and abuse, alcoholism, depression and domestic violence are the most relevant problems mentioned by the study group. Professionals reported lack of adequate training, work overload, poor working conditions with feelings of professional impotence and frustration. To overcome these difficulties, professionals reported collective strategies, particularly experience sharing during team meetings and matrix support groups. The results indicate that the difficulties may put the professionals in a vulnerable state, similar to the patients they care for. The promotion of specialized and long term support should be reinforced, as well as the interaction with the local network of services and communities leaders. That may help professionals to deal with occupational stress related to medical and social needs present in their routine work; in the end, it may as well contribute to the strengthening of FHS.

Articulação entre serviços públicos de saúde nos cuidados voltados à saúde mental infantojuvenil

O objetivo do estudo é descrever e analisar as articulações que se realizam entre as equipes da Estratégia Saúde da Família (ESF) e Centro de Atenção Psicossocial Infantojuvenil (CAPSI), tendo em vista as ações voltadas à saúde mental de crianças e adolescentes. Foram realizadas entrevistas semidirigidas com gerentes de cinco CAPSI e 13 Unidades Básicas de Saúde com ESF, de 5 regiões distintas no Município de São Paulo, Brasil, que foram transcritas e analisadas mediante perspectiva hermenêutica. A articulação entre as equipes da ESF e CAPSI se dá prioritariamente por encaminhamento de casos, apoio matricial ou parceria para casos considerados pertinentes ao CAPSI. Falta de recursos humanos, cobrança por produtividade e ausência de capacitação dos profissionais da ESF para trabalhar com saúde mental foram mencionadas como obstáculos para a efetiva articulação entre os serviços. A lógica do encaminhamento e da desresponsabilização, bem como a hegemonia do modelo biomédico e a consequente fragmentação dos cuidados se mostram vigentes no cotidiano dos serviços.

Apoio matricial em saúde mental: alcances e limites na atenção básica

As mudanças na atenção à saúde mental no município de Fortaleza têm um processo histórico e político recente, comparada a outros municípios cearenses, que no início dos anos 1990 já se lançavam pioneiros no processo. Fortaleza não implementou as mudanças devido aos interesses dos hospitais psiquiátricos, ambulatórios de psiquiatria da rede pública e dificuldade de gestão dos novos dispositivos e equipamentos de saúde mental presentes na Atenção Básica (AB). No município, a reorganização das ações e serviços de saúde mental tem exigido da Rede Básica o enfrentamento do desafio de atender aos problemas de saúde mental com a implementação do Apoio Matricial (ApM). Mediante o contexto, buscou-se avaliar o ApM em saúde mental em Unidades Básicas de Saúde (UBS) e identificar alcances e limites nas Unidades Básicas de Saúde com ApM. O presente estudo utilizou uma abordagem qualitativa, tipo estudo de caso. Foram entrevistados doze profissionais das Equipes de Saúde da Família de quatro UBS com apoio matricial implantado. A análise das informações revela que o acesso, a tomada de decisão, a participação e os desafios da implementação do ApM são elementos que se apresentam de forma dialética frágeis e fortes na reorganização dos serviços e das práticas. A presença do ApM na AB ressalta a proposta de trabalhar saúde mental em rede no município. O processo não está findo. Mobilização, sensibilização e capacitação da AB precisam ser incrementadas constantemente, mas a implementação tem possibilitado, ao serviço e aos profissionais, maior aceitação da saúde mental na AB.

Venomics Profiling of Thamnodynastes strigatus Unveils Matrix Metalloproteinases and Other Novel Proteins Recruited to the Toxin Arsenal of Rear-Fanged Snakes

Rear-fanged and aglyphous snakes are usually considered not dangerous to humans because of their limited capacity of injecting venom. Therefore, only a few studies have been dedicated to characterizing the venom of the largest parcel of snake fauna. Here, we investigated the venom proteome of the rear-fanged snake Thamnodynastes strigatus, in combination with a transcriptomic evaluation of the venom gland. About 60% of all transcripts code for putative venom components. A striking finding is that the most abundant type of transcript (similar to 47%) and also the major protein type in the venom correspond to a new kind of matrix metalloproteinase (MMP) that is unrelated to the classical snake venom metalloproteinases found in all snake families. These enzymes were recently suggested as possible venom components, and we show here that they are proteolytically active and probably recruited to venom from a MMP-9 ancestor. Other unusual proteins were suggested to be venom components: a protein related to lactadherin and an EGF repeat-containing transcript. Despite these unusual molecules, seven toxin classes commonly found in typical venomous snakes are also present in the venom. These results support the evidence that the arsenals of these snakes are very diverse and harbor new types of biologically important molecules.

Indices representing landscape as a support for pedological survey in GIS environment

Mapping of soil has been highlighted in the scientific community, because as alertness about the environment increases, it is necessary to understand more and more about the distribution of the soil in the landscape, as well as its potential and its limitations for the use. In that way the main aim of this study was to apply indices representing landscape with the use of geoprocessing to give support in the delimitation of different compartments of landscape. Primary indices used were altitude above channel network (AACN) and secondary channel network base level (CNBL), multiresolution index of valley bottom flatness (MRVBF) and Wetness index (ITW), having as object of study the Canguiri Experimental Farm, located in Pinhais, Curitiba's Metropolitan region. To correlate the chemical attributes and granulometric ones in sampling groups, totalizing 17 points (Sugamosto, 2002), a matrix of a simple linear correlation (Pearson) with the indices of the landscape were generated in the Software Statistica. The conclusion is that the indices representing the landscape used in the analysis of groupings were efficient as support to map soil at the level of suborder of Brazilian Soil Classification System.

Influence of a hypercholesterolemic diet on the collagen composition of the bladder wall extracellular matrix in rats

Purpose: To investigate the effects of hypercholesterolemic diet on the collagen composition of urinary bladder wall. Materials and methods: Forty-five female 4-week-old Wistar rats were divided into three groups: 1) control group fed a normal diet (ND); 2) model of bladder outlet obstruction (BOO) group fed a ND; and 3) group fed a HCD (1.25% cholesterol). Total serum cholesterol, LDL cholesterol and body weight were assessed at baseline. Four weeks later, group 2 underwent a surgical procedure resulting in a partial BOO, while groups 1 and 3 underwent a sham similar surgical procedure. Six weeks later, all animals had their bladders removed; serum cholesterol and LDL cholesterol levels and body weights were measured. Morphological and morphometric analysis was performed by Picrosirius staining and collagen types I and III were identified by immunofluorescence. Statistical analysis was completed and significance was considered when p<0.05. Results: Rats fed an HCD exhibited a significant increase in LDL cholesterol levels (p<0.001) and body weight (p=0.017), when compared to the groups fed a ND during the ten-week study period. Moreover, the HCD induced morphological alterations of the bladder wall collagen, regarding thin collagen fibers and the amounts of type III collagen when compared to the control group (p=0.002 and p=0.016, respectively), resembling the process promoted in the BOO model. Conclusions: A hyper-cholesterolemic diet in Wistar rats promoted morphological changes of the bladder types of collagen, as well as increases in body weight and LDL cholesterol.

Magnetic and optical investigation of 40SiO(2)center dot 30Na(2)O center dot 1Al(2)O(3)center dot(29-x) B2O3 center dot xFe(2)O(3) glass matrix

Samples of 40SiO(2)center dot 30Na(2)O center dot 1Al(2)O(3)center dot(29 - x)B2O3 center dot xFe(2)O(3) (mol%), with 0.0 <= x <= 17.5, were prepared by the fusion method and investigated by electron paramagnetic resonance (EPR), optical absorption (OA) and Mossbauer spectroscopy (MS). The EPR spectra of the as-synthesized samples exhibit two well-defined EPR signals around g = 4.27 and g = 2.01 and a visible EPR shoulder around g = 6.4, assigned to isolated Fe3+ ion complexes (g = 4.27 and g = 6.4) and Fe3+-based clusters (g = 2.01). Analyses of both EPR line intensity and line width support the model picture of Fe3+-based clusters built in from two sources of isolated ions, namely Fe2+ and Fe3+; the ferrous ion being used to build in iron-based clusters at lower x-content (below about x = 2.5%) whereas the ferric ion is used to build in iron-based clusters at higher x-content (above about x = 2.5%). The presence of Fe2+ ions incorporated within the glass template is supported by OA data with a strong band around 1100 nm due to the spin-allowed E-5(g)-T-5(2g) transition in an octahedral coordination with oxygen. Additionally, Mossbauer data (isomer shift and quadrupole splitting) confirm incorporation of both Fe2+ and Fe3+ ions within the template, more likely in tetrahedral-like environments. We hypothesize that ferrous ions are incorporated within the glass template as FeO4 complex resulting from replacing silicon in non-bridging oxygen (SiO3O-) sites whereas ferric ions are incorporated as FeO4 complex resulting from replacing silicon in bridging-like oxygen silicate groups (SiO4).

Long-term type 1 diabetes impairs decidualization and extracellular matrix remodeling during early embryonic development in mice

Introduction: Endometrial decidualization and associated extracellular matrix (ECM) remodeling are critical events to the establishment of the maternal-fetal interface and successful pregnancy. Here, we investigated the impact of type 1 diabetes on these processes during early embryonic development, in order to contribute to the understanding of the maternal factors associated to diabetic embryopathies. Methods: Alloxan-induced diabetic Swiss female mice were bred after different periods of time to determine the effects of diabetes progression on the development of gestational complications. Furthermore, the analyses focused on decidual development as well as mRNA expression, protein deposition and ultrastructural organization of decidual ECM. Results: Decreased number of implantation sites and decidual dimensions were observed in the group mated 90-110 days after diabetes induction (D), but not in the 50-70D group. Picrosirius staining showed augmentation in the fibrillar collagen network in the 90e110D group and, following immunohistochemical examination, that this was associated with increase in types I and V collagens and decrease in type III collagen and collagen-associated proteoglycans biglycan and lumican. qPCR, however, demonstrated that only type I collagen mRNA levels were increased in the diabetic group. Alterations in the molecular ratio among distinct collagen types and proteoglycans were associated with abnormal collagen fibrillogenesis, analyzed by transmission electron microscopy. Conclusions: Our results support the concept that the development of pregnancy complications is directly related with duration of diabetes (progression of the disease), and that this is a consequence of both systemic factors (i.e. disturbed maternal endocrine-metabolic profile) and uterine factors, including impaired decidualization and ECM remodeling
