Reassessing the status of antiphospholipid syndrome in systemic lupus erythematosus.

The antiphospholipid syndrome was initially described in 1986. To reassess the validity of antiphospholipid antibodies in systemic lupus erythematosus (SLE), 95 patients with SLE were studied. Their antiphospholipid antibody profile was analysed and correlated with clinical findings such as thrombosis, abortions, or thrombocytopenia. A low prevalence of these antibodies was found (13 patients; 14%) with a high specificity for thrombosis (92%) and abortions (92%). The importance of anticardiolipin antibodies as a risk factor for thrombosis or abortions, or both, in patients with SLE is reaffirmed by this work.

Epigenetic regulation of histone H3 serine 10 phosphorylation status by HCF-1 proteins in C. elegans and mammalian cells.

BACKGROUND: The human herpes simplex virus (HSV) host cell factor HCF-1 is a transcriptional coregulator that associates with both histone methyl- and acetyltransferases, and a histone deacetylase and regulates cell proliferation and division. In HSV-infected cells, HCF-1 associates with the viral protein VP16 to promote formation of a multiprotein-DNA transcriptional activator complex. The ability of HCF proteins to stabilize this VP16-induced complex has been conserved in diverse animal species including Drosophila melanogaster and Caenorhabditis elegans suggesting that VP16 targets a conserved cellular function of HCF-1. METHODOLOGY/PRINCIPAL FINDINGS: To investigate the role of HCF proteins in animal development, we have characterized the effects of loss of the HCF-1 homolog in C. elegans, called Ce HCF-1. Two large hcf-1 deletion mutants (pk924 and ok559) are viable but display reduced fertility. Loss of Ce HCF-1 protein at reduced temperatures (e.g., 12 degrees C), however, leads to a high incidence of embryonic lethality and early embryonic mitotic and cytokinetic defects reminiscent of mammalian cell-division defects upon loss of HCF-1 function. Even when viable, however, at normal temperature, mutant embryos display reduced levels of phospho-histone H3 serine 10 (H3S10P), a modification implicated in both transcriptional and mitotic regulation. Mammalian cells with defective HCF-1 also display defects in mitotic H3S10P status. CONCLUSIONS/SIGNIFICANCE: These results suggest that HCF-1 proteins possess conserved roles in the regulation of cell division and mitotic histone phosphorylation.

Type I IFNs at the interface between cutaneous immunity and epidermal remodeling.

Type I IFNs are key cytokines in antiviral host defense. Preferentially expressed by plasmacytoid dendritic cells, type I IFNs are induced by viral infection and in common skin wounds. In this issue, Tohyama et al. identify a new link between type I IFNs and epidermal remodeling, by showing that type I IFNs specifically upregulate IL-22R expression on keratinocytes and, thereby, IL-22-mediated Stat3 phosphorylation in keratinocytes. The findings suggest that type I IFNs play dual roles in human skin: first, they induce immune activation with the induction of IL-22-producing T cells; second, they provide the interface between immune activation and epidermal remodeling by increasing keratinocyte responsiveness to IL-22.

The health status of children without resident permit consulting the Children's Hospital of Lausanne.

OBJECTIVE: To assess social, economic and medical data concerning children without a resident permit taken into care by the Children's Hospital of Lausanne (HEL) in order to evaluate their specific needs. METHODS: Prospective exploratory study by a questionnaire including the socio-demographic, medical and education data of 103 children without a resident permit, who consulted the HEL for the first time between August 2003 and March 2006. These children were then recalled for a second check-up one year later in order to allow a regular monitoring. RESULTS: Eighty-seven percent of the children were native of Latin America, 36% being less than two years old. This population of children lived in precarious conditions with a family income lower than the poverty level (89% of the families with less than 3100 CHF/month). Forty-five percent of the children had a health insurance. The main reasons for consultation were infectious diseases, a check-up requested by the school or a check-up concerning newborn children. Most of them were in good health and the others were affected by illnesses similar to those found in other children of the same age. At least 13% of the children were obese and 27% were overweight. All children who were of educational age went to school during the year after the first check-up and 48% were affiliated to a health insurance. CONCLUSIONS: The majority of the children from Latin America lived in very precarious conditions. Their general health status was good and most of them could benefit from regular check-ups. Prevention, focused on a healthier life style, was particularly important among this population characterised by a high incidence of overweight and obesity.

Road Use Tax Fund Efficiency Report Savings Status, December 31,

Develop, in conjunction with the regional planning affiliations and metropolitan planning organizations and other stakeholder groups, a process to exchange STP federal funds for Primary Highway System funds for the purpose of reducing the number of small projects that have to meet onerous federal requirements. In order to implement this recommendation, legislative action is required to eliminate the restriction on using Primary Road Fund revenue on local jurisdiction roadways in exchange for a portion of their federal STP funding. This past session, Iowa DOT worked with legislators to introduce a bill in both the House and the Senate to eliminate this Code restriction. Bills were discussed at the subcommittee level in both the House and Senate but did not proceed because of the need to have further discussions with impacted parties. Prior to next session, discussions will occur amongst all impacted parties to reach consensus on how this recommendation could be implemented. With that consensus in place prior to next session, it is anticipated that the bills can be reintroduced next session.

Heterologous prime-boost regimen adenovector 35-circumsporozoite protein vaccine/recombinant Bacillus Calmette-Guérin expressing the Plasmodium falciparum circumsporozoite induces enhanced long-term memory immunity in BALB/c mice.

BACKGROUND: Sustained antibody levels are a hallmark of immunity against many pathogens, and induction of long-term durable antibody titers is an essential feature of effective vaccines. Heterologous prime-boost approaches with vectors are optimal strategies to improve a broad and prolonged immunogenicity of malaria vaccines. RESULTS: In this study, we demonstrate that the heterologous prime-boost regimen Ad35-CS/BCG-CS induces stronger immune responses by enhancing type 1 cellular producing-cells with high levels of CSp-specific IFN-γ and cytophilic IgG2a antibodies as compared to a homologous BCG-CS and a heterologous BCG-CS/CSp prime-boost regimen. Moreover, the heterologous prime-boost regimen elicits the highest level of LLPC-mediated immune responses. CONCLUSION: The increased IFN-γ-producing cell responses induced by the combination of Ad35-CS/BCG-CS and sustained type 1 antibody profile together with high levels of LLPCs may be essential for the development of long-term protective immunity against liver-stage parasites.

Radioimmunotherapy combined with maintenance anti-CD20 antibody may trigger long-term protective T cell immunity in follicular lymphoma patients.

Growing evidence suggests that the patient's immune response may play a major role in the long-term efficacy of antibody therapies of follicular lymphoma (FL). Particular long-lasting recurrence free survivals have been observed after first line, single agent rituximab or after radioimmunotherapy (RIT). Rituximab maintenance, furthermore, has a major efficacy in prolonging recurrence free survival after chemotherapy. On the other hand, RIT as a single step treatment showed a remarkable capacity to induce complete and partial remissions when applied in recurrence and as initial treatment of FL or given for consolidation. These clinical results strongly suggest that RIT combined with rituximab maintenance could stabilize the high percentages of patients with CR and PR induced by RIT. While the precise mechanisms of the long-term efficacy of these 2 treatments are not elucidated, different observations suggest that the patient's T cell immune response could be decisive. With this review, we discuss the potential role of the patient's immune system under rituximab and RIT and argue that the T cell immunity might be particularly promoted when combining the 2 antibody treatments in the early therapy of FL.

Escola e status racial em Cachoeira do Campo/MG no século XIX

De acordo com uma documentação que contabilizou a população de Minas Gerais, nos anos de 1830, havia um predomínio dos negros entre os alunos das escolas de instrução elementar. Neste artigo, procuramos investigar os significados dessa experiência para a população negra através da confrontação de documentos censitários do distrito de Cachoeira do Campo/MG, que se encontrava no termo de Ouro Preto, na região central da província. O procedimento de análise ocorreu a partir da separação dos domicílios em que havia o registro de crianças frequentando escolas, em 1831. Em seguida, identificamos esses domicílios na documentação de 1838 analisando a situação dos indivíduos escolarizados e de seu grupo familiar. O intervalo de sete anos entre os documentos possibilitou a avaliação dos impactos da experiência escolar, revelando, entre outras coisas, que negros escolarizados eram preferencialmente designados como pardos e estes podiam mudar de status racial, passando até mesmo a ser classificados como brancos.

Recurrence of status epilepticus: Prognostic role and outcome predictors.

OBJECTIVE: Predictors of morbidity and mortality after status epilepticus (SE) have been studied extensively in hospital- and population-based cohorts. However, little attention has been directed toward SE recurrence after an incident episode. We investigated clinical and demographic characteristics of patients presenting SE recurrence and its specific prognostic role. METHODS: In this observational cohort study, we screened our prospective registry of consecutive adults with SE between April 2006 and February 2014. Demographic and clinical data were compared between incident and recurrent SE episodes; risk of SE recurrence was assessed through survival analysis, and the prognostic role of SE recurrence with multivariable logistic regressions. RESULTS: Of the incident cohort (509 patients), 68 (13%) experienced recurrent SE. The cumulative recurrence rate over 4 years was 32%. Recurrence risk was significantly reduced after an acute SE etiology (hazard ratio [HR] 0.5, 95% confidence interval [CI] 0.31-0.82; p = 0.005), and was borderline increased in women (HR 1.59, 95% CI 0.97-2.65; p = 0.06). Although recurrent SE episodes showed lower morbidity and mortality, prognosis was independently related to Status Epilepticus Severity Score (STESS) and potentially fatal etiology, but not to SE recurrence. SIGNIFICANCE: This study provides class III evidence that SE recurrence involves a significant proportion of patients, and that recurrence risk is independently associated with chronic etiology and to a lesser extent with female gender. However, contrary to underlying cause and SE severity, SE recurrence per se does not independently correlate with outcome. Early identification of patients at higher risk of SE recurrence may influence their management during follow-up.
