Brote de brucelosis interprovincial por ingesta de queso fresco sin higienizar

Goal: To study an August 2004 outbreak of brucellosis notified in Velez-Rubio (Almeria) and to determine the source of that infection as well as its transmission mechanisms, in addition to proposing preventive measures. Methodology: Descriptive study and paired case controls (three controls were selected for each case). Setting: Health Centers in de Vélez-Rubio (Almeria) and Alcalá de Guadaira (Seville). Population: Suspected/probable case: a person with compatible clinical symptoms and positive brusella agglutination diagnosed between July 2005 and March 2005. Confirmed case: in addition to identifying the causal agent, laboratory test results resulted in a confirmation. Interventions: Report forms, epidemiological surveys, clinical histories, and laboratory tests were used as sources of data. Odds ratios (OR) and confidence intervals were calculated to study the relationship among cases, sources of infection, and transmission mechanisms. The Chi Square test and Yates correction were employed. Results: 10 cases were identified (9 in Almeria and 1 in Seville), 8 of them pobable and 2 confirmed, in persons between the ages of 45 and 81. The symptoms first appeared between the months of May and September 2005. Fever was the most frequent symptom (100%). The OR for the consumption of fresh, non.-pasteurized cheese was 112 (CI 4,48-16968,94), p< 0,001. Infected animals were intervened. Conclusions: The inter-provincial outbreak of brucellosis was confirmed as stemming from the consumption of non-pasteurized cheese sold on the street. The source of infection was identified and the Department of Agriculture carried out the necessary actions.

EFNS guidelines on the clinical management of amyotrophic lateral sclerosis (MALS)--revised report of an EFNS task force.

BACKGROUND: The evidence base for the diagnosis and management of amyotrophic lateral sclerosis (ALS) is weak. OBJECTIVES: To provide evidence-based or expert recommendations for the diagnosis and management of ALS based on a literature search and the consensus of an expert panel. METHODS: All available medical reference systems were searched, and original papers, meta-analyses, review papers, book chapters and guidelines recommendations were reviewed. The final literature search was performed in February 2011. Recommendations were reached by consensus. RECOMMENDATIONS: Patients with symptoms suggestive of ALS should be assessed as soon as possible by an experienced neurologist. Early diagnosis should be pursued, and investigations, including neurophysiology, performed with a high priority. The patient should be informed of the diagnosis by a consultant with a good knowledge of the patient and the disease. Following diagnosis, the patient and relatives/carers should receive regular support from a multidisciplinary care team. Medication with riluzole should be initiated as early as possible. Control of symptoms such as sialorrhoea, thick mucus, emotional lability, cramps, spasticity and pain should be attempted. Percutaneous endoscopic gastrostomy feeding improves nutrition and quality of life, and gastrostomy tubes should be placed before respiratory insufficiency develops. Non-invasive positive-pressure ventilation also improves survival and quality of life. Maintaining the patient's ability to communicate is essential. During the entire course of the disease, every effort should be made to maintain patient autonomy. Advance directives for palliative end-of-life care should be discussed early with the patient and carers, respecting the patient's social and cultural background.

Spread of Phlebotominae in temperate climates: province of Córdoba, Argentina

We report the presence of the competent vector for Leishmaniaspp, Migonemyia migonei, and theEvandromyia cortelezzii-sallesi complex south of its known distribution in the central temperate region of Argentina, in the province of Córdoba. The persistence of this phlebotomine in the northern border of the province, its association with a case of cutaneous leishmaniasis, and the new record in the outskirts of the city of Córdoba, the second most populated in the country, strengthens the need for regular vector surveillance and a case detection-sensitive health system in vulnerable regions, even in temperate climates.

Domains of p85cdc10 required for function of the fission yeast DSC-1 factor.

p85cdc10 is a component of the S.pombe DSC-1 complex, which is thought to mediate periodic transcription of genes in late G1. In order to understand the role of p85cdc10 in the function of this complex, we have analysed which domains of p85cdc10 are required for biological activity and the formation of a stable DSC-1 complex in vitro, both in cdc10 temperature sensitive and null backgrounds. No DSC-1 activity is found in the absence of p85cdc10 and the activity of the complex is reduced or absent in all cdc10ts mutants tested. Full biological activity and rescue of a cdc10::ura4+ null allele requires the N-terminal domain, the cdc10/SWI6 repeats and the helical C-terminal region. In the absence of p85cdc10, both the C-terminal and cdc10/SWI6 repeat domains are required for DSC-1 activity in vitro. In a cdc10ts background, rescue of DSC-1 activity and complementation of mutants, requires only expression of the C-terminal domain, though the presence of the cdc10/SWI6 motifs enhances its activity. The N-terminal domain, alone, or in combination with the cdc10/SWI6 motifs, does not have biological activity, and does not restore DSC-1 activity. We conclude that both the C-terminal domain of p85cdc10 is critical for formation of the DSC-1 complex and that the cdc10/SWI6 motifs also play a role, perhaps by stabilizing the complex. Our data also suggest that the S.pombe DSC-1 complex contains more than one molecule of p85cdc10.

Effect of a pathological scapular tilt after total shoulder arthroplasty.

Total shoulder arthroplasty (TSA) is an accepted and most successfully used treatment for different shoulder pathologies. Different risk factors for the failure of the prosthesis are known. A pathological scapular orientation, observed in elderly people or in patients suffering from neuromuscular diseases, could be a cause of failure, which has not been investigated yet. To test this hypothesis, a numerical musculoskeletal model of the glenohumeral joint was used to compare two TSA cases: a reference normal case and a case with a pathological anterior tilt of the scapula. An active abduction of 150° was simulated. Joint force, contact pattern, polyethylene and cement stress were evaluated for both cases. The pathological tilt slightly increased the joint force and the contact pressure, but also shifted the contact pattern. This eccentric contact increased the stress level within the polyethylene of the glenoid component and within the surrounding cement layer. This adverse effect occurred mainly during the first 60° of abduction. Therefore, a pathological orientation of the scapula may increase the risk of a failure of the cement layer around the glenoid component. These preliminary numerical results should be confirmed by a clinical study.

Le devenir féminin transgenre : une étude qualitative et réflexive sur le genre, la corporéité et la subjectivité sexuelle

RésuméCette thèse en psychologie qualitative et critique de la santé propose un éclairage, sur la subjectivité transgenre, différent des modèles dominants en clinique. Les nosologies de type DSM et de la psychiatrie dominante focalisent sur la seule question de la transition transsexuelle, elles utilisent la sexualité comme outil dans les diagnostics différentiels permettant d'effectuer le gatekeeping de la transition médicalisée du genre. Elles sont décrites comme un dispositif de médicalisation du genre, induisant des pratiques maltraitantes. Une méthodologie qualitative inspirée de la théorie ancrée ainsi que de l'analyse réflexive est utilisée. Un échantillon de 15 personnes représentant la diversité des personnes transgenres FtM a été recruté. Les données provenant d'entrevues non directives sont analysées dans une perspective verticale et horizontale. Les résultats soulignent l'inadéquation des typologies cliniques, de la place qui est donnée à la sexualité dans les procédures diagnostiques et de l'opposition qu'elles construisent entre identité (de genre) et sexualité. Ils plaident pour une vision deleuzienne de type nomade, incarnée et sexuée de la subjectivité transgenre.AbstractThe broad of this study in critical health psychology is to build an understanding of transgender subjectivity which contrast with dominant clinical models. DSM nosology types and dominant psychiatry have traditionally focused only on transsexual transitioning. They use sexuality as a diagnostic tool to address the gatekeeping of the medical transition. These practices have been described as medicalization of gender, inducing mistreatment. A qualitative methodology mixing grounded theory and reflexivity has been used. A sample of 15 persons has been recruited to represent transgender FtM diversity. Data were collected through in-depth interview and analysed case by case and by themes. Results show that dominant clinical typologies of TG are inappropriate, as well as the way sexuality is used in this practices and the opposition between (gender) identity and sexuality. We propose a deleuzian concept of becoming and multiplicity to understand transgender subjectivity.

Steel Diaphragms in Prestressed Concrete Girder Bridges, September 2004

Over the years, bridge engineers have been concerned about the response of prestressed concrete (PC) girder bridges that had been hit by over-height vehicles or vehicle loads. When a bridge is struck by an over-height vehicle or vehicle load, usually the outside and in some instances one of the interior girders are damaged in a bridge. The effect of intermediate diaphragms in providing damage protection to the PC girders of a bridge is not clearly defined. This analytical study focused on the role of intermediate diaphragms in reducing the occurrence of damage in the girders of a PC-girder bridge that has been struck by an over-height vehicle or vehicle load. The study also investigated whether a steel, intermediate diaphragm would essentially provide the same degree of impact protection for PC girders as that provided by a reinforced-concrete diaphragm. This investigation includes the following: a literature search and a survey questionnaire to determine the state-of-the-art in the use and design of intermediate diaphragms in PC-girder bridges. Comparisons were made between the strain and displacement results that were experimentally measured for a large-scale, laboratory, model bridge during previously documented work and those results that were obtained from analyses of the finite-element models that were developed during this research for that bridge. These comparisons were conducted to calibrate the finite element models used in the analyses for this research on intermediate diaphragms. Finite-element models were developed for non-skewed and skewed PC-girder bridges. Each model was analyzed with either a reinforced concrete or two types of steel, intermediate diaphragms that were located at mid-span of an interior span for a PC-girder bridge. The bridge models were analyzed for lateral-impact loads that were applied to the bottom flange of the exterior girders at the diaphragms location and away from the diaphragms location. A comparison was conducted between the strains and displacements induced in the girders for each intermediate-diaphragm type. These results showed that intermediate diaphragms have an effect in reducing impact damage to the PC girders. When the lateral impact-load was applied at the diaphragm location, the reinforced-concrete diaphragms provided more protection for the girders than that provided by the two types of steel diaphragms. The three types of diaphragms provided essentially the same degree of protection to the impacted, PC girder when the lateral-impact load was applied away from the diaphragm location.

Guidelines for the Conversion of Urban Four-Lane Undivided Roadways to Three-Lane Two-Way Left-turn Lane Facilities, April 2001

Four-lane undivided roadways in urban areas can experience a degradation of service and/or safety as traffic volumes increase. In fact, the existence of turning vehicles on this type of roadway has a dramatic effect on both of these factors. The solution identified for these problems is typically the addition of a raised median or two-way left-turn lane (TWLTL). The mobility and safety benefits of these actions have been proven and are discussed in the “Past Research” chapter of this report along with some general cross section selection guidelines. The cost and right-of-way impacts of these actions are widely accepted. These guidelines focus on the evaluation and analysis of an alternative to the typical four-lane undivided cross section improvement approach described above. It has been found that the conversion of a four-lane undivided cross section to three lanes (i.e., one lane in each direction and a TWLTL) can improve safety and maintain an acceptable level of service. These guidelines summarize the results of past research in this area (which is almost nonexistent) and qualitative/quantitative before-and-after safety and operational impacts of case study conversions located throughout the United States and Iowa. Past research confirms that this type of conversion is acceptable or feasible in some situations but for the most part fails to specifically identify those situations. In general, the reviewed case study conversions resulted in a reduction of average or 85th percentile speeds (typically less than five miles per hour) and a relatively dramatic reduction in excessive speeding (a 60 to 70 percent reduction in the number of vehicles traveling five miles per hour faster than the posted speed limit was measured in two cases) and total crashes (reductions between 17 to 62 percent were measured). The 13 roadway conversions considered had average daily traffic volumes of 8,400 to 14,000 vehicles per day (vpd) in Iowa and 9,200 to 24,000 vehicles per day elsewhere. In addition to past research and case study results, a simulation sensitivity analysis was completed to investigate and/or confirm the operational impacts of a four-lane undivided to three-lane conversion. First, the advantages and disadvantages of different corridor simulation packages were identified for this type of analysis. Then, the CORridor SIMulation (CORSIM) software was used x to investigate and evaluate several characteristics related to the operational feasibility of a four-lane undivided to three-lane conversion. Simulated speed and level of service results for both cross sections were documented for different total peak-hour traffic, access densities, and access-point left-turn volumes (for a case study corridor defined by the researchers). These analyses assisted with the identification of the considerations for the operational feasibility determination of a four -lane to three-lane conversion. The results of the simulation analyses primarily confirmed the case study impacts. The CORSIM results indicated only a slight decrease in average arterial speed for through vehicles can be expected for a large range of peak-hour volumes, access densities, and access-point left-turn volumes (given the assumptions and design of the corridor case study evaluated). Typically, the reduction in the simulated average arterial speed (which includes both segment and signal delay) was between zero and four miles per hour when a roadway was converted from a four-lane undivided to a three-lane cross section. The simulated arterial level of service for a converted roadway, however, showed a decrease when the bi-directional peak-hour volume was about 1,750 vehicles per hour (or 17,500 vehicles per day if 10 percent of the daily volume is assumed to occur in the peak hour). Past research by others, however, indicates that 12,000 vehicles per day may be the operational capacity (i.e., level of service E) of a three-lane roadway due to vehicle platooning. The simulation results, along with past research and case study results, appear to support following volume-related feasibility suggestions for four-lane undivided to three-lane cross section conversions. It is recommended that a four-lane undivided to three-lane conversion be considered as a feasible (with respect to volume only) option when bi-directional peak-hour volumes are less than 1,500 vehicles per hour, but that some caution begin to be exercised when the roadway has a bi-directional peak-hour volume between 1,500 and 1,750 vehicles per hour. At and above 1,750 vehicles per hour, the simulation indicated a reduction in arterial level of service. Therefore, at least in Iowa, the feasibility of a four-lane undivided to three-lane conversion should be questioned and/or considered much more closely when a roadway has (or is expected to have) a peak-hour volume of more than 1,750 vehicles. Assuming that 10 percent of the daily traffic occurs during the peak-hour, these volume recommendations would correspond to 15,000 and 17,500 vehicles per day, respectively. These suggestions, however, are based on the results from one idealized case xi study corridor analysis. Individual operational analysis and/or simulations should be completed in detail once a four-lane undivided to three-lane cross section conversion is considered feasible (based on the general suggestions above) for a particular corridor. All of the simulations completed as part of this project also incorporated the optimization of signal timing to minimize vehicle delay along the corridor. A number of determination feasibility factors were identified from a review of the past research, before-and-after case study results, and the simulation sensitivity analysis. The existing and expected (i.e., design period) statuses of these factors are described and should be considered. The characteristics of these factors should be compared to each other, the impacts of other potentially feasible cross section improvements, and the goals/objectives of the community. The factors discussed in these guidelines include • roadway function and environment • overall traffic volume and level of service • turning volumes and patterns • frequent-stop and slow-moving vehicles • weaving, speed, and queues • crash type and patterns • pedestrian and bike activity • right-of-way availability, cost, and acquisition impacts • general characteristics, including - parallel roadways - offset minor street intersections - parallel parking - corner radii - at-grade railroad crossings xii The characteristics of these factors are documented in these guidelines, and their relationship to four-lane undivided to three-lane cross section conversion feasibility identified. This information is summarized along with some evaluative questions in this executive summary and Appendix C. In summary, the results of past research, numerous case studies, and the simulation analyses done as part of this project support the conclusion that in certain circumstances a four-lane undivided to three-lane conversion can be a feasible alternative for the mitigation of operational and/or safety concerns. This feasibility, however, must be determined by an evaluation of the factors identified in these guidelines (along with any others that may be relevant for a individual corridor). The expected benefits, costs, and overall impacts of a four-lane undivided to three-lane conversion should then be compared to the impacts of other feasible alternatives (e.g., adding a raised median) at a particular location.

Melastatin Expression in Ocular Melanocytic Proliferations

Purpose: Melastatin (MLSN-1) belongs to the transient receptor potential (TRP) superfamilly of calcium-permeable channels, and has been reported to be a melanocyte-specific gene. In human cutaneous melanoma, MLSN-1 mRNA expression displays a pattern of inverse correlation to disease free survival. We describe the patterns of MLSN-1 mRNA expression in conjunctival nevi, conjunctival melanoma, and uveal melanoma. Methods: In situ hybridization using two S35-labelled riboprobes for MLSN-1 was performed on formalin-fixed, paraffin-embedded tissues. A control probe for H4 histone was used to confirm mRNA integrity in these archival tissues. The 21 ocular melanocytic lesions studied included 5 conjunctival nevi, 6 conjunctival melanomas, and 10 enucleated eyes with uveal melanoma. The minimal requirement for interpretation of MLSN-1 mRNA loss was the presence of only background signal in a focus of at least 5 adjacent melanocytic cells. Results: Ubiquitous expression of MLSN-1 mRNA was found in conjunctival melanocytes in the non-lesional epithelium adjacent to the conjunctival melanocytic proliferations and in all 5 conjunctival nevi studied. Four different patterns of MLSN-1 mRNA expression were observed in conjunctival melanomas: one case showed complete preservation of MLSN-1 mRNA, two cases showed diffuse scattered loss of MLSN-1 mRNA, two cases showed focal clonal loss of MLSN-1 mRNA expression, and one case had no detected MLSN-1 mRNA. In uveal melanomas, MLSN-1 mRNA expression was partially preserved in two cases, lost by a clearly delimited subset of tumor cells (focal clonal loss) in four cases, and was not detectable in the entire tumor in four cases. MLSN-1 mRNA expression was also found in the normal iris, ciliary and choroidal melanocytes as well as in the retinal pigmented epithelium and in the inner nuclear layer of the retina. Conclusions: The patterns of MLSN-1 mRNA expression in the ocular melanocytic proliferations are similar to those reported in cutaneous melanocytic proliferations. In the conjunctiva, MLSN-1 mRNA expression appeared to correlate with tumor progression; all the benign conjunctival nevi had preserved expression of MLSN-1 mRNA and most of the conjunctival melanomas partial or complete loss of expression. In uveal melanoma, patterns of melastatin expression ranging from partial preservation to complete loss were found. Additional studies of a large number of ocular melanocytic proliferations may show a correlation with tumor progression and prognosis similar to that observed in cutaneous melanoma.

Dealing with Errors in QCA

This paper discusses five strategies to deal with five types of errors in Qualitative Comparative Analysis (QCA): condition errors, systematic errors, random errors, calibration errors, and deviant case errors. These strategies are the comparative inspection of complex, intermediary, and parsimonious solutions; the use of an adjustment factor, the use of probabilistic criteria, the test of the robustness of calibration parameters, and the use of a frequency threshold for observed combinations of conditions. The strategies are systematically reviewed, assessed, and evaluated as regards their applicability, advantages, limitations, and complementarities.

Gastric outlet obstruction by Brunner's gland hyperplasia in an 8-year-old child.

Several cases of Brunner's gland hyperplasia causing hemorrhage, obstruction, or intussusception have been published in the adult literature. Similar cases in the pediatric population are very rare and have only been described twice, always associated with chronic renal failure. We report the third and youngest case of gastric outlet obstruction because of Brunner's gland hyperplasia focusing on histopathologic condition and treatment based on a review of the literature.

Development of a Safety protocol for Management Thirst in the Immediate Postoperative Period

Objective To develop a safety protocol for the management of thirst in the immediate postoperative period. Method Quantitative, methodological, and applied study conducted in April-August 2012. An extensive literature search and expert consultation was carried out to develop the protocol and its operating manual. Theoretical and semantic analyzes were carried out by experts. Results Assessment of level of consciousness, reflexes of protection of the airways (cough and swallowing), and absence of nausea and vomiting were selected as safety criteria. These criteria were grouped and formatted in a graph algorithm, which indicates the need to interrupt the procedure if a security criterion does not reach the expected standard. Conclusion The protocol was elaborated to fill in the gap in the literature of a specific model concerning nursing actions in the safe management of thirst in the immediate postoperative period.

O Processo de Raciocínio na Teoria dos Constrangimentos Aplicado numa Instituição de Ensino Superior

A Teoria dos Constrangimentos (TOC) ou das Restrições tem-se mostrado uma valiosa ferramenta de gestão, auxiliando na identificação dos constrangimentos que limitem a capacidade das empresas na prossecução da sua meta. Assim, para as restrições não físicas, a TOC desenvolveu o Processo de Raciocínio que é composto por ferramentas de análise lógica que dão subsídios para o diagnóstico de problemas bem como a formulação de soluções e planos de acção para implementá-las. Neste contexto, este trabalho se propõe a determinar a adequação do Processo de Raciocínio da Teoria dos Constrangimentos numa Instituição de Ensino Superior (IES) como forma de diagnosticar os problemas e propor soluções capazes de permitir a empresa uma melhoria contínua do seu desempenho. Serão avaliadas as ferramentas que compõem o Processo de Raciocínio, que são: Árvore de Realidade Actual, Diagrama de Dispersão de nuvens, Árvore de Realidade Futura, Árvore de Pré-Requisitos e Árvore de Transição. O trabalho inicia-se com uma pesquisa bibliográfica seguida de uma pesquisa de campo e finalizando com uma aplicação do PR numa IES localizada na ilha de São Vicente. A colecta de informações para a análise processou-se mediante a aplicação de um questionário fechado aos discentes e funcionários, questionário aberto aos docentes e entrevista estruturada aos dirigentes, elaborados em coerência com os objectivos que este estudo pretende atingir. Os resultados da aplicação do método aqui apresentado permitiram chegar as conclusões apontadas no capítulo final deste trabalho The Theory of Constraints (TOC) or Restriction Theory has proved to be a valuable management tool, assisting in the identification of constraints that restrict the ability of companies in the pursuit of its goals. Therefore, for the nonphysical constraints, TOC developed the Thinking Process (TP) that consists of logical analysis tools that provide a basis for diagnosing problems and formulating solutions and action plans to implement them. This study aims, thus, to determine the suitability of the use of the Thinking Process of the Theory of Constraints in a Higher Education Institution (HEI) as a way to diagnose problems and propose solutions that enable the firm to continually improve their performance. We will evaluate the tools that make up the TP, which are: Current Reality Tree, Evaporating Cloud Diagram, Future Reality Tree, Prerequisites Tree and Transition Tree. The work starts with a literature review, followed by a field search, and finishes with an application of the reasoning process in a higher education institution, located in São Vicente. The collection of the data for the analysis was processed through the application of a closed questionnaire to students and staff, opened questionnaire to teachers and interviews to management, drafted in line with the objectives that this study aims to reach. The results of the application of the method presented here, allowed us to reach the conclusions drawn in the final chapter of this work.

Association of a common vitamin D-binding protein polymorphism with inflammatory bowel disease.

OBJECTIVE: Inflammatory bowel diseases (IBDs), Crohn's disease, and ulcerative colitis (UC), are multifactorial disorders, characterized by chronic inflammation of the intestine. A number of genetic components have been proposed to contribute to IBD pathogenesis. In this case-control study, we investigated the association between two common vitamin D-binding protein (DBP) genetic variants and IBD susceptibility. These two single nucleotide polymorphisms (SNPs) in exon 11 of the DBP gene, at codons 416 (GAT>GAG; Asp>Glu) and 420 (ACG>AAG; Thr>Lys), have been previously suggested to play roles in the etiology of other autoimmune diseases. METHODS: Using TaqMan SNP technology, we have genotyped 884 individuals (636 IBD cases and 248 non-IBD controls) for the two DBP variants. RESULTS: On statistical analysis, we observed that the DBP 420 variant Lys is less frequent in IBD cases than in non-IBD controls (allele frequencies, P=0.034; homozygous carrier genotype frequencies, P=0.006). This inverse association between the DBP 420 Lys and the disease remained significant, when non-IBD participants were compared with UC (homozygous carrier genotype frequencies, P=0.022) or Crohn's disease (homozygous carrier genotype frequencies, P=0.016) patients separately. Although the DBP position 416 alone was not found to be significantly associated with IBD, the haplotype DBP_2, consisting of 416 Asp and 420 Lys, was more frequent in the non-IBD population, particularly notably when compared with the UC group (Odds ratio, 4.390). CONCLUSION: Our study adds DBP to the list of potential genes that contribute to the complex genetic etiology of IBD, and further emphasizes the association between vitamin D homeostasis and intestinal inflammation.
