Distributed Hybrid Agent Based Intrusion Detection and Real Time Response System

Wireless LANs are growing rapidly and security has always been a concern. We have implemented a hybrid system, which will not only detect active attacks like identity theft causing denial of service attacks, but will also detect the usage of access point discovery tools. The system responds in real time by sending out an alert to the network administrator.

Late Adverse Effects of the Coadministration of Valproate and Lamotrigine

Individuals treated with combined valproate-lamotrigine rarely present late adverse effects (unrelated to introduction and titration). We describe four patients in whom such effects occurred after continuous, long-term use of valproate-lamotrigine (at 9 months to 2 years after final antiepileptic drug adjustment). The patients presented heterogeneous disturbances, including ataxia, vertigo, and headache, and rare movement disorders, such as tics and abnormal eye movements. Although these effects are heterogeneous in their occurrence and timing, they can alert physicians to the possibility of late neurologic disturbances, and must be considered in order to avoid unnecessary ancillary tests. Treatment discontinuation is unnecessary, given that a small decrease in dose led to remission of these adverse effects. (c) 2012 Elsevier Inc. All rights reserved.

Influence of Helmet Use in Facial Trauma and Moderate Traumatic Brain Injury Victims of Motorcycle Accidents

Objective: The objective of this research was to study the influence of the use of helmet in facial trauma victims of motorcycle accidents with moderate traumatic brain injury. Methods: We retrospectively reviewed the incidence of facial injuries in helmeted and nonhelmeted victims with moderate traumatic brain injury at a referral trauma hospital. Results: The sample consisted of 272 patients predominantly men (94.5%) and between 21 and 40 years old (62.9%). The majority of patients were using helmet (80.1%). The occurrence of facial fractures was most frequent for zygomatic bone (51.8%), followed by mandible (18.8%) and nasal bones (9.2%). Conclusions: Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them.

Efeitos de detomidina e xilazina intravenosa sobre as variáveis basais e respostas comportamentais em bovinos

Avaliaram-se, durante 60 minutos, 10 bovinos após administração intravenosa de 0,1mg.kg-1 de xilazina ou 10μg.kg-1 de detomidina, quanto às frequências cardíaca e respiratória, movimentos ruminais, pressão arterial média, temperatura retal e respostas comportamentais como ataxia ou decúbito, ptose palpebral, estado de alerta ou sedação e redução da altura da cabeça em relação ao solo, além da presença de salivação, micção e concentração sanguínea de glicose. Observou-se que a xilazina, via intravenosa, em bovinos, ao mesmo tempo que promove sedação mais intensa e prolongada que a detomidina, induz a uma maior quantidade de efeitos indesejáveis, como salivação e decúbito, e redução das frequências cardíaca e respiratória, da pressão arterial média, da motilidade ruminal e da temperatura, sendo estas alterações mais prolongadas. Conclui-se que a detomidina pode ser utilizada com segurança em bovinos na dose de 10μg.kg-1, promovendo sedação e permanência do animal em posição quadrupedal.

Paracoccidioides brasiliensis infection in dogs from Western Brazilian Amazon

The objective of the study was to evaluate Paracoccidioides brasiliensis infection in urban dogs from the municipality of Monte Negro, Rondonia, Western Brazilian Amazon. The serum samples (n=126) were analyzed by indirect ELISA and the immunodiffusion test using P. brasiliensis gp43 and exoantigen as antigens, respectively. A positivity of 54.8% was observed only in the ELISA test and no statistical difference was observed in the seroprevalence in relation to age or sex. This is the first paracoccidioidomycosis survey carried out with dogs from the Western Brazilian Amazon. The higher positivity rates of P. brasiliensis infection observed in this study suggest that veterinarians must be alert to detect new cases of natural disease in dogs living in paracoccidioidomycosis endemic areas.

Patient with toxoplasmosis and glucose-6-phosphate dehydrogenase deficiency: a case report

Abstract Introduction Toxoplasmosis, a zoonotic protozoal disease caused by toxoplasma gondii, is prevalent throughout the world, affecting a large proportion of persons who usually have no symptoms. Glucose 6 phosphate dehydrogenase deficiency, an X-linked inherited disorder, is present in over 400 million people world wide. It is more common in tropical and subtropical countries and is one of the important causes of hemolytic anemia. Case presentation This case report relates the occurrence of the two diseases simultaneously in a child of five years old. Conclusion Patients with glucose-6-phosphate dehydrogenase deficiency are more susceptible to toxoplasmosis and this case report, reinforce the findings of this propensity and alert us for such possibility, what it is important, therefore, the treatment of toxoplasmosis can cause serious hemolysis in these patients.

Behavioral meaningful opioidergic stimulation activates kappa receptor gene expression

The periaqueductal gray (PAG) has been reported to be a location for opioid regulation of pain and a potential site for behavioral selection in females. Opioid-mediated behavioral and physiological responses differ according to the activity of opioid receptor subtypes. The present study investigated the effects of the peripheral injection of the kappa-opioid receptor agonist U69593 into the dorsal subcutaneous region of animals on maternal behavior and on Oprk1 gene activity in the PAG of female rats. Female Wistar rats weighing 200-250 g at the beginning of the study were randomly divided into 2 groups for maternal behavior and gene expression experiments. On day 5, pups were removed at 7:00 am and placed in another home cage that was distant from their mother. Thirty minutes after removing the pups, the dams were treated with U69593 (0.15 mg/kg, sc) or 0.9% saline (up to 1 mL/kg) and after 30 min were evaluated in the maternal behavior test. Latencies in seconds for pup retrieval, grouping, crouching, and full maternal behavior were scored. The results showed that U69593 administration inhibited maternal behavior (P < 0.05) because a lower percentage of kappa group dams showed retrieval of first pup, retrieving all pups, grouping, crouching and displaying full maternal behavior compared to the saline group. Opioid gene expression was evaluated using real-time reverse-transcription polymerase chain reaction (RT-PCR). A single injection of U69593 increased Oprk1 PAG expression in both virgin (P < 0.05) and lactating female rats (P < 0.01), with no significant effect on Oprm1 or Oprd1 gene activity. Thus, the expression of kappa-opioid receptors in the PAG may be modulated by single opioid receptor stimulation and behavioral meaningful opioidergic transmission in the adult female might occur simultaneously to specific changes in gene expression of kappa-opioid receptor subtype. This is yet another alert for the complex role of the opioid system in female reproduction

A importância da análise dos gêneros para fisioterapeutas: enfoque nas quedas entre idosos

INTRODUÇÃO: O alto número de quedas entre pessoas idosas aumenta a demanda para reabilitação das debilidades físicas consequentes do evento, em clínicas de fisioterapia. Para evitar episódios recorrentes, o profissional dessa área deve alertá-los para práticas preventivas. Porém, trata-se de pessoas com diferentes contextos histórico-culturais e esquemas de rotina. OBJETIVO: Apontar as distinções entre gêneros como estratégia para a compreensão do cotidiano programado desses indivíduos. MATERIAIS E MÉTODOS: Análise qualitativa, utilizando entrevista semiestruturada, partindo do tema da influência da queda na vida diária. As falas são transcritas codificadas e, posteriormente, categorizadas expressando as ideias encontradas no pensamento do idoso. RESULTADOS: A queda doméstica está inserida no campo de trabalho da mulher (o lar) e, por isso, gera preocupação à medida que interfere nos hábitos do cotidiano referentes àquilo que define sua função no espaço e na vida. O homem parece preocupar-se com quedas quando ela impossibilita-o de manter um vínculo com o ambiente externo, o seu ambiente. CONCLUSÃO: Dessa forma, percebe-se que o gênero é uma categoria operacional em que se definem, para cada um, prioridades diferentes. Por meio de tal olhar, consegue-se justificar e compreender algumas relações de dominação existentes no seio da sociedade e que, ao fisioterapeuta, contribuem para que sejam discernidas certas particularidades entre pacientes que interferem na adesão a seus aconselhamentos preventivos.

Cross-layer optimizations in multi-hop ad hoc networks

Unlike traditional wireless networks, characterized by the presence of last-mile, static and reliable infrastructures, Mobile ad Hoc Networks (MANETs) are dynamically formed by collections of mobile and static terminals that exchange data by enabling each other's communication. Supporting multi-hop communication in a MANET is a challenging research area because it requires cooperation between different protocol layers (MAC, routing, transport). In particular, MAC and routing protocols could be considered mutually cooperative protocol layers. When a route is established, the exposed and hidden terminal problems at MAC layer may decrease the end-to-end performance proportionally with the length of each route. Conversely, the contention at MAC layer may cause a routing protocol to respond by initiating new routes queries and routing table updates. Multi-hop communication may also benefit the presence of pseudo-centralized virtual infrastructures obtained by grouping nodes into clusters. Clustering structures may facilitate the spatial reuse of resources by increasing the system capacity: at the same time, the clustering hierarchy may be used to coordinate transmissions events inside the network and to support intra-cluster routing schemes. Again, MAC and clustering protocols could be considered mutually cooperative protocol layers: the clustering scheme could support MAC layer coordination among nodes, by shifting the distributed MAC paradigm towards a pseudo-centralized MAC paradigm. On the other hand, the system benefits of the clustering scheme could be emphasized by the pseudo-centralized MAC layer with the support for differentiated access priorities and controlled contention. In this thesis, we propose cross-layer solutions involving joint design of MAC, clustering and routing protocols in MANETs. As main contribution, we study and analyze the integration of MAC and clustering schemes to support multi-hop communication in large-scale ad hoc networks. A novel clustering protocol, named Availability Clustering (AC), is defined under general nodes' heterogeneity assumptions in terms of connectivity, available energy and relative mobility. On this basis, we design and analyze a distributed and adaptive MAC protocol, named Differentiated Distributed Coordination Function (DDCF), whose focus is to implement adaptive access differentiation based on the node roles, which have been assigned by the upper-layer's clustering scheme. We extensively simulate the proposed clustering scheme by showing its effectiveness in dominating the network dynamics, under some stressing mobility models and different mobility rates. Based on these results, we propose a possible application of the cross-layer MAC+Clustering scheme to support the fast propagation of alert messages in a vehicular environment. At the same time, we investigate the integration of MAC and routing protocols in large scale multi-hop ad-hoc networks. A novel multipath routing scheme is proposed, by extending the AOMDV protocol with a novel load-balancing approach to concurrently distribute the traffic among the multiple paths. We also study the composition effect of a IEEE 802.11-based enhanced MAC forwarding mechanism called Fast Forward (FF), used to reduce the effects of self-contention among frames at the MAC layer. The protocol framework is modelled and extensively simulated for a large set of metrics and scenarios. For both the schemes, the simulation results reveal the benefits of the cross-layer MAC+routing and MAC+clustering approaches over single-layer solutions.

Adequacy of venous thromboprophylaxis in acutely ill medical patients (IMPART): multisite comparison of different clinical decision support systems

BACKGROUND: The adequacy of thromboprophylaxis prescriptions in acutely ill hospitalized medical patients needs improvement. OBJECTIVE: To prospectively assess the efficacy of thromboprophylaxis adequacy of various clinical decision support systems (CDSS) with the aim of increasing the use of explicit criteria for thromboprophylaxis prescription in nine Swiss medical services. METHODS: We randomly assigned medical services to a pocket digital assistant program (PDA), pocket cards (PC) and no CDSS (controls). In centers using an electronic chart, an e-alert system (eAlerts) was developed. After 4 months, we compared post-CDSS with baseline thromboprophylaxis adequacy for the various CDSS and control groups. RESULTS: Overall, 1085 patients were included (395 controls, 196 PC, 168 PDA, 326 eAlerts), 651 pre- and 434 post-CDSS implementation: 472 (43.5%) presented a risk of VTE justifying thromboprophylaxis (31.8% pre, 61.1% post) and 556 (51.2%) received thromboprophylaxis (54.2% pre, 46.8% post). The overall adequacy (% patients with adequate prescription) of pre- and post-CDSS implementation was 56.2 and 50.7 for controls (P = 0.29), 67.3 and 45.3 for PC (P = 0.002), 66.0 and 64.9 for PDA (P = 0.99), 50.5 and 56.2 for eAlerts (P = 0.37), respectively, eAlerts limited overprescription (56% pre, 31% post, P = 0.01). CONCLUSION: While pocket cards and handhelds did not improve thromboprophylaxis adequacy, eAlerts had a modest effect, particularly on the reduction of overprescription. This effect only partially contributes to the improvement of patient safety and more work is needed towards institution-tailored tools.

[Ethics, empiricism and uncertainty]

Accidents can lead to difficult boundary situations. Such situations often take place in the emergency units. The medical team thus often and inevitably faces professional uncertainty in their decision-making. It is essential to communicate these uncertainties within the medical team, instead of downplaying or overriding existential hurdles in decision-making. Acknowledging uncertainties might lead to alert and prudent decisions. Thus uncertainty can have ethical value in treatment or withdrawal of treatment. It does not need to be covered in evidence-based arguments, especially as some singular situations of individual tragedies cannot be grasped in terms of evidence-based medicine.

Glucocorticoid treatment, immobility, and constipation are associated with nutritional risk

Purpose The hypothesis of this clinical study was to determine whether glucocorticoid use and immobility were associated with in-hospital nutritional risk. Methods One hundred and one patients consecutively admitted to the medical wards were enrolled. Current medical conditions, symptoms, medical history, eating and drinking habits, diagnosis, laboratory findings, medications, and anthropometrics were recorded. The Nutrition Risk Score 2002 (NRS-2002) was used as a screening instrument to identify nutritional risk. Results The results confirmed that glucocorticoid use and immobility are independently associated with nutritional risk determined by the NRS-2002. Constipation could be determined as an additional cofactor independently associated with nutritional risk. Conclusions Glucocorticoid treatment, immobility, and constipation are associated with nutritional risk in a mixed hospitalized population. The presence of long-time glucocorticoid use, immobility, or constipation should alert the clinician to check for nutritional status, which is an important factor in mortality and morbidity.

Pulmonary edema at recovery after colic operation with in-situ nasogastric tube in a horse

After an uneventful general anesthesia, in a horse negative pressure pulmonary edema developed due to acute upper airway obstruction during the anesthetic recovery phase after colic surgery. No pathologic alteration of respiration was observed until the horse stood up and began suffocating. The horse had recovered with the nasogastric tube in situ. This, together with the postmortem diagnosis of laryngeal hemiplegia resulted in impairment of airflow through the larynx and development of pulmonary edema. Our objective is to alert clinicians about the possible hazard of recovery with an in-situ nasogastric tube.
