The standpoint of professionals on the presence and demands of men on the healthcare services: perspectives for the analysis of the implementation of the Comprehensive Healthcare Policy for Men

In 2009, the Brazilian Comprehensive Healthcare Policy for Men (PNAISH) was launched in Brazil, seeking to reduce morbidity and mortality in this population group. This article strives to analyze the conceptions that health professionals have about the specific demands and behaviors of the male population served by the healthcare services. The data analyzed are part of a larger research project, the objective of which was to evaluate the initial actions of the implementation of PNAISH. Ethnographic observations in 11 health services and semi-structured interviews were conducted with 21 health professionals. From the perspective of health professionals, the presence of men in the healthcare services is still limited. According to them, it is comprised of two types of clients: workers and the elderly. The male behavior characteristics - haste, objectivity, fear and resistance - and the difficulty faced by health services in receiving this population are the main factors that drive men away from health services. Although the concept of gender is central to PNAISH, it is only triggered by healthcare professionals in order to justify the social standards expected in terms of men's behavior. The attribution of men's behavior to cultural factors ultimately obscures the relations of power that underlie gender relations.

The viewpoint of health professionals on the role of basic units in the healthcare network of the Brazilian Unified Health System

In the process of creation of the Unified Health System (SUS) as a universal policy seeking to ensure comprehensive care, unscheduled assistance in primary healthcare units (UBS) is an unresolved challenge. The scope of this paper is to analyze the viewpoint of health professionals on the role of primary healthcare units in meeting this demand. It is a transversal study of qualitative data obtained through questionnaires and interviews with 106 medical practitioners from 6 emergency medical services and 190 professionals from 30 units. They explained why people seek emergency care for occurrences pertaining to primary care. The content analysis technique with thematic categories was used for data analysis. Lack of resources and problems with primary health unit work processes (50.8%) were the reasons most frequently cited by emergency care physicians to explain this inadequate demand. Only 33.3% of the health unit professionals agreed that these occurrences should be attended in the primary healthcare services. The limited viewpoint of the role of health services on the unscheduled care, particularly among primary care professionals, possibly leads to restrictive practices for access by the population.

CARING FOR TUBERCULOSIS PATIENTS IN THE FAMILY HEALTH STRATEGY: THE NURSES' PERCEPTIONS

The objective of this study was to analyze the nurses' perceptions regarding tuberculosis control, according to the theoretical axis of comprehensive healthcare and the concepts of attachment and teamwork. This qualitative study involved 13 nurses from the Family Health Strategy of a priority city in the metropolitan region of Joao Pessoa, Paraiba, Brazil. Data were collected in focal groups and subjected to thematic content analysis. Factors that strengthen tuberculosis control were: supervised treatment, free medication and the provision of supplies. Weakening factors were: worker's turnover, the lack of encouragement for patients and incipient educational actions. The factors that, according to the nurses, weaken tuberculosis patient care should be reviewed by administrators, workers, users and educators with a view to redefining healthcare activities that strengthen attachment, comprehensive healthcare and teamwork.

Necessidades de saúde, políticas públicas e gênero: a perspectiva das práticas profissionais

Examina-se a relação entre políticas públicas e práticas dos profissionais, relativamente às necessidades de saúde. Em abordagem teórico-conceitual, as práticas são definidas como desempenhos permeados por determinantes técnico-cien­tíficos e sócio-históricos para a produção social de um trabalho, analisando-se suas possibilidades de mudanças culturais, éticas e políticas, para um agir crítico das desigualdades de gênero. Tomando-se a atenção integral à saúde dos homens, examina-se a relevância da distinção entre necessidades masculinas e femininas, enquanto realidades parciais não necessariamente convergentes na (re)produção daquelas desigualdades. Igualmente se examinam as práticas profissionais, como realidade parcial e distinta das políticas, estabelecendo relações não imediatas. Desenvolve-se que são obstáculos simbólicos e práticos para mudanças: a normalização biomédica redutora das necessidades, a cultura do trabalho autônomo e da abordagem individualizante das necessidades, a cultura tradicional de gênero conservando práticas desiguais para homens e mulheres e a ausência de inscrição dos direitos como parte do agir profissio­nal. Isto exige propostas específicas às práticas de saúde e às necessidades masculinas para maior convergência com as reformas das políticas.

Caminhos da integralidade: adolescentes e jovens na atenção primária à saúde

Adolescentes e jovens constituem importante desafio para a construção da integralidade na Atenção Primária à Saúde (APS). Isso se deve à complexa apreensão e resposta ao conjunto de suas necessidades de saúde, decorrentes do processo de crescimento e desenvolvimento, próprio da fase, mas, sobretudo, dos aspectos socioculturais relacionados. O presente estudo buscou reconhecer alcances e limites em como o princípio da integralidade vem sendo operado em uma Unidade Básica de Saúde. Embora tenha sido possível identificar uma efetiva percepção da especificidade necessária à atenção à saúde desse grupo, também se verificaram importantes limitações relacionadas à construção de projetos de cuidado capazes de integrar as diversas finalidades do trabalho no cotidiano da Unidade, com destaque para a insuficiência de interações profissionais e setoriais, e fragilidades na comunicação de profissionais entre si e de profissionais e usuários.

The identification of the pillars of education in the class comprehensiveness in healthcare

The objective of the present study was to verify, based on the analysis of student portfolio narratives, if the four pillars of education were approached in the class "Comprehensiveness in health care", part of the integrated curriculum of the Baccalaureate in Nursing Program of the University of Sao Paulo at Ribeirao Preto College of Nursing. A qualitative, documental study was performed using 46 portfolios constructed during the classes. Data collection was performed using an assessment tool that contained items addressing cognitive and affective dimensions. The data were submitted to thematic categorical analysis using the pillars of education as predefined categories. The results show that the pillars of education were, apparently, included in the class. Despite the present study findings, no evidence was found that the expected competencies were actually discussed among students and faculty, according to the records regarding the evaluations of each pedagogical cycle of the studied class.

Evaluation of comprehensive two-dimensional gas chromatography coupled to rapid scanning quadrupole mass spectrometry for quantitative analysis

Comprehensive two-dimensional gas chromatography (GC x GC) is a powerful technique that provides excellent separation and identification of analytes in highly complex samples with considerable increase in GC peak capacities. However, since second dimension analyses are very fast, detectors with a rapid acquisition rate are required. Over the last years, quite a number of studies have discussed the potential and limitations of the combination GC x GC with a variety of quadrupole mass spectrometers. The present research focuses on the evaluation of qMS effectiveness at a 10,000-amu/s scan speed and 20-Hz scan frequency for the identification (full scan mode acquisition-TIC) and quantification (extracted ion chromatogram) of target pesticide residues in tomato samples. The following MS parameters have been evaluated: number of data points per peak, mass spectrum quality, peak skewing, and sensitivity. The validated proposed GC x GC/qMS method presented satisfactory results in terms of repeatability (coefficient of variation lower than 15%), accuracy (84-117%), and linearity (ranging from 25 to 500 ng/g), while significant enhancement in sensitivity was observed (a factor of around 10) under scan conditions.

Evaluation of quality of life in severely obese patients after bariatric surgery carried out in the public healthcare system

Objectives: To assess QoL of obese patients in the Brazilian public healthcare system, before and after bariatric surgery, and to determine the appropriateness of the Moorehead-Ardelt Questionnaire II (M-A-QoLQII) compared with the Short-Form Health Survey (SF-36). Subjects and methods: Forty-one severe obese patients in a waiting-list, and 84 patients who underwent bariatric surgery were included. Correlations were tested and reliability determined by the Cronbach's coefficient. Results: BMI differed between the pre- and post-surgery groups (52.3 +/- 8.3 kg/m(2) vs. 32.5 +/- 6.4 kg/m(2), p < 0.001). The latter showed better scores in the SF-36 domains than in the pre-surgery. SF-36 and M-A-QoLQII categories were correlated (r = 0.53, 0.49 and 0.47, for vitality, mental health, and general health domains, p < 0.001). In the logistic regression, age, previous BMI, and loss of excess weight were associated with functional capacity. Conclusions:The outcomes of bariatric surgery obtained in a Brazilian public healthcare center were successful. M-A-QoLII represents a useful tool to assess surgery outcomes, including QoL.

Comprehensive Evaluation of the Effects of Enalapril on Matrix Metalloproteinases Levels in Hypertension

Angiotensin-converting enzyme inhibitors (ACEi) may downregulate matrix metalloproteinases (MMPs). We examined whether enalapril affects MMP-2, MMP-8, and MMP-9 levels and activity, and their endogenous inhibitors (tissue inhibitors of MMPs, TIMP-1 and TIMP-2) levels in hypertensive patients. Moreover, we assessed the effects of enalaprilat on MMP-9 and TIMP-1 secretion by human endothelial cells (HUVECs). Thirty-eight hypertensive patients received enalapril for 8 weeks and were compared with thirty-eight normotensive controls. Blood samples were collected at baseline and after treatment. Plasma ACE activity was determined by a fluorimetric assay. Plasma MMP-2, MMP-8, MMP-9, TIMP-1, and TIMP-2 were measured by ELISA and gelatin zymography. A fluorogenic peptide cleavage assay was used to measure MMP activity. HUVECs cells were stimulated by phorbol-12-myristate-13-acetate (PMA) and the effects of enalaprilat (10(-10) to 10(-6) M) on MMP-9 and TIMP-1 levels were determined. Enalapril decreased blood pressure and ACE activity in hypertensive patients (P < 0.05), but had no effects on plasma MMP-2, MMP-8, MMP-9, TIMP-1, and TIMP-2 levels, or MMP activity. Enalaprilat had no effects on PMA-induced increases in MMP-9 and TIMP-1 secretion by HUVECs or on MMP activity. We show consistent evidence, both in vivo and in vitro, that enalapril does not affect MMPs and TIMPs levels in hypertensive patients.

THE CARE NEEDS OF WOMEN INFECTED WITH THE HUMAN PAPILLOMA VIRUS: A COMPREHENSIVE APPROACH

This study is founded on the phenomenology of Martin Heidegger, with the objective to understand the care needs of women infected with the human papilloma virus. Participants were fourteen women who had been diagnosed with this infection. The guiding questions were: What is it like to have this diagnosis? Tell me your experience, from when you received your diagnosis until today. What has your health care been like? The questions revealed the theme - seeking care as solicitude - which showed the importance of the support of family and friends. The presence of the infection as the cause of marital conflicts and separation was another highlighted aspect. The statements showed that there was a sense of resignation after an unsuccessful attempt to find accurate and clear information in order to make assertive decisions. Health interventions for infected women must overcome the traditional models of care, including interventions for health promotion and prevention, with trained professionals who are sensitive to the subjective dimension.

Primary healthcare and the construction of meanings of oral health: a social constructionist interpretation of discourses of the elderly

Dentistry currently reveals itself to be open to new ideas about the construction of meanings for oral health. This openness leads to the social production of health revealing the contextualization of the social and historical aspects of the sundry knowledge in the development of oral health for different communities. With this research, we seek to build meanings for oral health with a group of elderly people. With this objective in mind, we propose an approximation between discourses on oral health mentioned by the elderly and the Social Constructionist discourse. We interviewed 14 elderly people enrolled in a Family Health Unit in Ribeirao Preto, State of Sao Paulo, in the first semester of 2010, and identified two interpretative repertoires through Discourse Analysis, which showed the relationship between 1 Lack of information and dental assistance in childhood, and 2 - Primary Health Care building the meaning of oral health. We concluded that Social Constructionism works epistemologically for the construction of meanings for oral health and that primary health is essential for appreciation and health care that enables the construction of meanings in oral health by the elderly that create conditions for self-care and healthy attitudes.

Solid-phase microextraction combined with comprehensive two-dimensional gas chromatography for fatty acid profiling of cell wall phospholipids

The combination of solid-phase microextraction (SPME) with comprehensive two-dimensional gas chromatography is evaluated here for fatty acid (FA) profiling of the glycerophospholipid fraction from human buccal mucosal cells. A base-catalyzed derivatization reaction selective for polar lipids such as glycerophospholipid was adopted. SPME is compared to a miniaturized liquidliquid extraction procedure for the isolation of FA methyl esters produced in the derivatization step. The limits of detection and limits of quantitation were calculated for each sample preparation method. Because of its lower values of limits of detection and quantitation, SPME was adopted. The extracted analytes were separated, detected, and quantified by comprehensive two-dimensional gas chromatography with flame ionization detection (FID). The combination of SPME and comprehensive two-dimensional gas chromatography with FID, using a selective derivatization reaction in the preliminary steps, proved to be a simple and fast procedure for FA profiling, and was successfully applied to the analysis of adult human buccal mucosal cells.

MICROORGANISMS OF THE COCCIDIA SUBCLASS: RESISTANCE AND IMPLICATIONS FOR THE ASEPTIC PROCESSING OF HEALTHCARE PRODUCTS

This theoretical study proposes a reflection on the intrinsic resistance of the subclass Coccidia, particularly the genus Cryptosporidium, considered to be potential pathogens for immunocompromised patients, and the implications for nursing practice. Currently, the international and national guidelines support the chemical disinfection of digestive system endoscopes after their cleansing as a safe and effective procedure. However, studies show that microorganisms of the subclass Coccidia, namely Cryptosporidium, responsible for enteric infection, are more resistant than mycobacteria and are not inactivated by high-level disinfectants, except for hydrogen peroxide 6% and 7.5%, which are not currently available in Brazil. We conclude that the legislation should include this agent among test microorganisms for approving high-level disinfectants. Health authorities should make efforts to ensure that healthcare institutions have access to effective disinfectants against Cryptosporidium.

Regionalization and access to healthcare in Brazilian states: historical and political-institutional conditioning factors

This article examines the healthcare regionalization process in the Brazilian states in the period from 2007 to 2010, seeking to identify the conditions that favor or impede this process. Referential analysis of public policies and especially of historical institutionalism was used. Three dimensions sum up the conditioning factors of regionalization: context (historical-structural, political-institutional and conjunctural), directionality (ideology, object, actors, strategies and instruments) and regionalization features (institutionality and governance). The empirical research relied mainly on the analysis of official documents and interviews with key actors in 24 states. Distinct patterns of influence in the states were observed, with regionalization being marked by important gains in institutionality and governance in the period. Nevertheless, inherent difficulties of the contexts prejudice greater advances. There is a pressing need to broaden the territorial focus in government planning and to integrate sectorial policies for medium and long-term regional development in order to empower regionalization and to overcome obstacles to the access to healthcare services in Brazil.

Polymorphic toxin systems: Comprehensive characterization of trafficking modes, processing, mechanisms of action, immunity and ecology using comparative genomics

Background: Proteinaceous toxins are observed across all levels of inter-organismal and intra-genomic conflicts. These include recently discovered prokaryotic polymorphic toxin systems implicated in intra-specific conflicts. They are characterized by a remarkable diversity of C-terminal toxin domains generated by recombination with standalone toxin-coding cassettes. Prior analysis revealed a striking diversity of nuclease and deaminase domains among the toxin modules. We systematically investigated polymorphic toxin systems using comparative genomics, sequence and structure analysis. Results: Polymorphic toxin systems are distributed across all major bacterial lineages and are delivered by at least eight distinct secretory systems. In addition to type-II, these include type-V, VI, VII (ESX), and the poorly characterized "Photorhabdus virulence cassettes (PVC)", PrsW-dependent and MuF phage-capsid-like systems. We present evidence that trafficking of these toxins is often accompanied by autoproteolytic processing catalyzed by HINT, ZU5, PrsW, caspase-like, papain-like, and a novel metallopeptidase associated with the PVC system. We identified over 150 distinct toxin domains in these systems. These span an extraordinary catalytic spectrum to include 23 distinct clades of peptidases, numerous previously unrecognized versions of nucleases and deaminases, ADP-ribosyltransferases, ADP ribosyl cyclases, RelA/SpoT-like nucleotidyltransferases, glycosyltranferases and other enzymes predicted to modify lipids and carbohydrates, and a pore-forming toxin domain. Several of these toxin domains are shared with host-directed effectors of pathogenic bacteria. Over 90 families of immunity proteins might neutralize anywhere between a single to at least 27 distinct types of toxin domains. In some organisms multiple tandem immunity genes or immunity protein domains are organized into polyimmunity loci or polyimmunity proteins. Gene-neighborhood-analysis of polymorphic toxin systems predicts the presence of novel trafficking-related components, and also the organizational logic that allows toxin diversification through recombination. Domain architecture and protein-length analysis revealed that these toxins might be deployed as secreted factors, through directed injection, or via inter-cellular contact facilitated by filamentous structures formed by RHS/YD, filamentous hemagglutinin and other repeats. Phyletic pattern and life-style analysis indicate that polymorphic toxins and polyimmunity loci participate in cooperative behavior and facultative 'cheating' in several ecosystems such as the human oral cavity and soil. Multiple domains from these systems have also been repeatedly transferred to eukaryotes and their viruses, such as the nucleo-cytoplasmic large DNA viruses. Conclusions: Along with a comprehensive inventory of toxins and immunity proteins, we present several testable predictions regarding active sites and catalytic mechanisms of toxins, their processing and trafficking and their role in intra-specific and inter-specific interactions between bacteria. These systems provide insights regarding the emergence of key systems at different points in eukaryotic evolution, such as ADP ribosylation, interaction of myosin VI with cargo proteins, mediation of apoptosis, hyphal heteroincompatibility, hedgehog signaling, arthropod toxins, cell-cell interaction molecules like teneurins and different signaling messengers.
