Thrombophilia, Pulmonary Embolism (PE) and Deep Venous Thrombosis (DVT) in pregnant women: a brief communication

Venous thromboembolism (VTE), deep vein thrombosis and pulmonary embolism, are among the main causes of morbidity and mortality in pregnancy with an estimated incidence of 1 per thousand women years. Despite identification of maternal and pregnancy-specific risk factors for development of pregnancy-associated venous thromboembolism, limited data are available to inform on optimal approaches for prevention. The relatively low overall prevalence of pregnancyassociated venous thromboembolism has prompted debate about the validity of recommendations, which are mainly based on expert opinion, and have resulted in an increased use of pharmacological thromboprophylaxis in pregnancy and postpartum

Correlation between Bipolar Affective Disorder and Suicide Reviewing by the Risk Factors: a Systematic Review

Background: Because there are several reports associations between affective (AD) and bipolar disorder (BD) and suicide, the research develops a discussion of risk factors that inflence the occurrence of suicide attempts in patients with BD.Objectives: To relate risk factors present in patients with bipolar disorder who committed suicide or some suicide attempt.Methods: A survey was made in Scopus with the keyword "bipolar" and the terms "suicide" and "attempted"and "risk factors" from Medical Subject Headings (MeSH). We use only Scopus as the data source, and the statistical information available in tables and graphs provided from this source.Results: Frequently the AD and BD were associated with suicide occurrence in the studies included in this review. They identifid the main risk factors for suicide the previous suicide attempt and hopelessness. The main risk factors for nonfatal suicidal behavior included family history of suicide, early onset of bipolar disorder, extent of depressive symptoms, increasing severity of affective episodes, the presence of mixed affective states, rapid cycling, comorbid Axis I disorders, and abuse of alcohol or drugs. The suicide rate in this disorder reaches three times compared with other mental illnesses, and there are several risk factors: 3:1 ratio of suicide in men compared to women, but in females a greater number of attempts are observed. 25% of persons consume alcohol prior to suicidal attempt. The studies relate these factors and show how they can pose a risk to the carrier of the disorder. There are other risk factor for BD discussed on this review.Conclusions: It is inferred that the factors related to the risk of suicide in patients with bipolar disorder are important to enable the development of strategies designed to identify a possible suicidal ideation, prevention and control of these deaths. These elements are well characterized and defied in the studies

Ebola: an international public health emergency

The outbreak of Ebola in West Africa could become one of the worst infectious-disease-driven humanitarian crises of recent times. With more than 3000 deaths since the first case was confirmed in March 2014, the international community has recognized Ebola as a public health emergency of international concern and a clear threat to global health security. The complexity of dealing with this Ebola outbreak has highlighted the need for traditional actors, such as WHO and the CDC, to embrace the wider health and humanitarian community. The epidemic reinforces the need for nations to investment in health infrastructure and disease surveillance to keep pace with other developments in Africa. If Ebola arrives in high-income and middleincome nations, it should be contained quickly. The crisis shows the importance of sufficient levels of multilateral funding for WHO. The world needs a strong WHO, with the financing and political influence to fulfil its historic mission

Diagnosing congenital toxoplasmosis: where are we? A systematic review

Purpose: Compile information on laboratory methods for diagnosis of congenital toxoplasmosis, considering the tests conducted since the gestational stage until the child period. Methods:A systematic review of 01.01.2006 to 31.12.2013 was held by VHL (Virtual Health Library). The search was performed with the descriptors ''toxoplasmosis†and “diagnosis. The selected articles were indexed in MEDLINE. The information pertinent to the study was selected, categorized and analyzed. Of the 186 articles found, 41 met the eligibility criteria. Results: Laboratory tests are based on the presence of antibodies IgM and IgG anti-Toxoplasma gondii, in this sense it is important to correctly interpret serology, because the detection of specific antibodies is often delayed by the presence of maternal IgG or late production of specific antibodies in newborns. Molecular techniques (PCR) have emerged as alternative due to its higher sensitivity and specificity in diagnosing instruments, given the ability to detect parasite DNA and non-dependence of the immune response of the patient, such as serological tests.Conclusions: The need for early treatment of congenital toxoplasmosis in order to avoid sequelae justifies the search for more sensitive and specific laboratory tests in early detection of the parasite. Theintegration among the different levels of care in the public health system is essential for obtaining effective control of toxoplasmosis in pregnant women.Â

Plagiarism as another ethical issue in scientific research

The excessive demand for publications results in high plagiarism and duplicate numbers by scientists who take over existing texts into new publications. In addition to serious ethical problems, this practice hinders the generation of original material. In order to reduce the problem, softwares such as eTBLAST are being used to detect plagiarism and repeated papers. Despite the persistence of fraudsters, these tools have helped to reduce these problems; however, the ideal solution would be the basic ethical establishment principles. Therefore, plagiarism has always been a foible that could lead to fraudulent and dishonorable development of science

The Importance Of Neuronal Plasticity In The Prognosis Of Cases Of Cerebral Ischemia: A Systematic Review

Background: Neuronal plasticity is the capacity that the neurons have to make new connections and enable new ways of transmitting information. Under this context, new methodologies are being addressed in order to measure how important this neuronal capacity is in the process of full recovery of learning in subjects who suffered damage from cerebral ischemia.Methods: A systematic review was performed on the online databases: Medical Literature Analysis and Retrieval System Online (MEDLINE) and Scopus, between 1998 and 2014. The MeSH (Medical Subject Headings) descriptors used in this review were: "neuronal plasticity", "brain ischemia" and "learning". We found 164 articles that, when screened, resulted in 46 articles that met the criteria of evidence and were included in this review.Results: There are several ways available in the literature to increase neuronal plasticity to keep the learning process after bad conformations resulting from cerebral ischemia. We highlighted the most elucidated: those promoted by SMe1EC2 antioxidant, which brings therapeutic benefits when neuronal plasticity is impaired; and Atorvastatin, a statin which facilitates recovery of spatial learning. It is further observed that the body has a number of intrinsic devicessuch as the endogenous compensatory mechanisms that contribute to the development of neuronal plasticity when there is brain damage caused by ischemia.Conclusion: The improvement of neuronal plasticity appears in several studies mapped as a new and still little explored possibility of treatment of damages caused by brain processes of oxygen deprivation. Multiple devices, endogenous and exogenous, that promote an increase in neuronal plasticity, are being elucidated in an attempt to promote the full recovery of the learning process, decreased by brain damage from ischemic processes. Thus, it is pointed the necessity of scientific studies that allows to define and maximize the potentials of the neuronal plasticity

The development of Resistance to Antiretroviral Therapy for HIV Infected Individuals:a Systematic Review

Background: Antiretroviral treatment (ART) has reduced morbidity and mortality due to AIDS. However, treatment options can be impaired by the development of antiretroviral drug resistance. Resistant virus strains can be transmitted to new hosts and, subsequently, can lead to antiretroviral treatment failure.Methods: Th A systematic review of articles on resistance to antiretroviral therapy for HIV-infected individuals, published from January 1, 2014 to June 16, 2014, on SCOPUS and PUBMED databases wascarried out. Search terms were "AIDS" (Medical Subject Headings [MeSH]), "HIV" (MeSH), “treatment†(keyword), “resistance†(keyword) and "antiretroviral therapy" (MeSH). Of the 118 retrieved studies, 24 met the eligibility criteria.Results: The main classes of antiretroviral drugs are Non Nucleoside Reverse Transcriptase Inhibitors (NNRTIs), Nucleoside Reverse Transcriptase Inhibitors (NRTIs), and Protease Inhibitors (PIs). Antiretroviraltreatment selects for drug resistance. Resistant strains become prevalent in the population and are transmitted to new patients.Discussion: A higher prevalence of certain mutations are present and characterize resistant strains that are prevalent in the population making it more diffiult to treat these infected individuals. Poor compliance with antiretroviral therapy increases the potential for developing these and other resistant strains.Conclusions: Knowledge of drug resistance generated by mutations is useful for optimizing treatment regimens and to get better responses. Promoting compliance is important to limiting the selection of new resistant strains

Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV

A search for a narrow-width resonance decaying into two Higgs bosons, each decaying into a bottom quark-antiquark pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ at $\sqrt{s}=$ 13 TeV recorded by the CMS detector at the LHC. No evidence for such a signal is observed. Upper limits are set on the product of the production cross section for the resonance and the branching fraction for the selected decay mode in the resonance mass range from 260 to 1200 GeV
