Emergency endovascular treatment of cavernous internal carotid artery acute bleeding with flow diverter stent: a single-center experience
Background and objective To describe our single-center experience in the treatment of cavernous internal carotid artery (ICA) acute bleeding with flow diverter stent (FDS), as a single endovascular procedure or combined with an endoscopic endonasal approach. Methods We analyze a case series of 5 patients with cavernous ICA acute bleeding, i.e., 3 iatrogenic, 1 post-traumatic, and 1 erosive neoplastic. After an immediate nasal packing to temporarily bleeding control, patients underwent digital subtraction angiography (DSA) to identify the site of the ICA injury. A concomitant balloon occlusion test (BOT) was performed, to exclude post-occlusive ischemic neurological damage. An FDS was placed with parallel intravenous infusion of abciximab in 3 cases and tirofiban in 2 cases. In two patients, an innovative "sandwich technique" combining the endovascular reconstruction with an extracranial intrasphenoidal cavernous ICA resurfacing with autologous flaps or grafts by endoscopic endonasal approach was performed. Results No patient had periprocedural ischemic-hemorrhagic complications. All patients had a regular clinical evolution, without general complications or new onset of focal neurological deficits. No further bleeding occurred in 3 patients, while 2 cases experienced a mild rebleeding in a period ranging from 5 to 15 days after the endovascular procedure. In these two cases, we proceeded with an endoscopic endonasal procedure to resurface the exposed ICA wall in the sphenoid sinus. Conclusions Although the treatment of choice for cavernous ICA acute bleeding remains the occlusion of the injured vessel, in cases of poor hemodynamic compensation at the BTO, the endovascular FDS emergency placement can be effective. A combined endoscopic endonasal technique to support the extracranial side of the vessel using autologous flaps or grafts can be performed to prevent the risk of rebleeding
General Characteristics and Risk Factors of Cardiovascular Disease among Interstate Bus Drivers
Workers in the transportation industry are at greater risk of an incorrect diet and sedentary behavior. The aim of our study was to characterize a population of professional bus drivers with regard to clinical and demographic variables, lipid profile, and the presence of cardiovascular risk factors. Data from 659 interstate bus drivers collected retrospectively, including anthropometric characteristics, systolic and diastolic blood pressure, lipid profile, fasting blood glucose, meatoscopy, and audiometry. All participants were male, with a mean age of 41.7 ± 6.9 years, weight of 81.4 ± 3.3âkg, and BMI 27.2 ± 3.3âKg/m2; the mean abdominal and neck circumferences were 94.4 ± 8.6âcm and 38.9 ± 2.2 âcm; 38.2% of the sample was considered hypertensive; mean HDL cholesterol was 47.9 ± 9.5âmg/dL, mean triglyceride level was 146.3 ± 87.9âmg/dL, and fasting glucose was above 100âmg/dL in 249 subjects (39.1%). Drivers exhibited reduced audiometric hearing at 4â8âkHz, being all sensorineural hearing loss. The clinical characterization of a young male population of interstate bus drivers revealed a high frequency of cardiovascular risk factors, as obesity, hypertension, hyperlipidemia, and hyperglycemia, as well as contributing functional characteristics, such as a low-intensity activity, sedentary behavior, long duration in a sitting position, and high-calorie diet, which lead to excessive weight gain and associated comorbidities
Redes sociales orientadas a la educaciĂłn y su integraciĂłn en contextos pre-existentes
Gracias a la denominada Web 2.0, internet se ha convertido en bidireccional y nos permite interactuar con otros usuarios. Cuando interactuamos con otros individuos estamos realizando una actividad social y formando comunidades. A estas comunidades, compuestas de personas conectadas por uno o varios tipos de relaciones, se las denomina redes sociales.
Cuando el interĂ©s comĂșn de estas comunidades es el aprendizaje, a estas redes se las denomina redes sociales educativas.
Las redes sociales se basan en los principios bĂĄsicos de comunicaciĂłn, cooperaciĂłn y colaboraciĂłn y utilizan un conjunto de servicios destinados a los integrantes de dicha red.
El objetivo de esta investigaciĂłn es: el estudio de los servicios que ofrecen las redes sociales, el anĂĄlisis de cĂłmo se integran esos servicios, el desarrollo de una guĂa de servicios que deben estar y el diseño una red social orientada a la educaciĂłn.Eje: TecnologĂa informĂĄtica aplicada en educaciĂłnRed de Universidades con Carreras en InformĂĄtica (RedUNCI
Intranasal trans-sialidase-based vaccine against Trypanosoma cruzi triggers a mixed cytokine profile in the nasopharynx-associated lymphoid tissue and confers local and systemic immunogenicity
Trypanosoma cruzi, the agent of Chagas disease, can infect through conjunctive or oral mucosas. Therefore, the induction of mucosal immunity by vaccination is relevant not only to trigger local protection but also to stimulate both humoral and cell-mediated responses in systemic sites to control parasite dissemination. In a previous study, we demonstrated that a nasal vaccine based on a Trans-sialidase (TS) fragment plus the mucosal STING agonist c-di-AMP, was highly immunogenic and elicited prophylactic capacity. However, the immune profile induced by TS-based nasal vaccines at the nasopharyngeal-associated lymphoid tissue (NALT), the target site of nasal immunization, remains unknown. Hence, we analyzed the NALT cytokine expression generated by a TS-based vaccine plus c-di-AMP (TSdA+c-di-AMP) and their association with mucosal and systemic immunogenicity. The vaccine was administered intranasally, in 3 doses separated by 15 days each other. Control groups received TSdA, c-di-AMP, or the vehicle in a similar schedule. We demonstrated that female BALB/c mice immunized intranasally with TSdA+c-di-AMP boosted NALT expression of IFN-Îł and IL-6, as well as IFN-ÎČ and TGF-ÎČ. TSdA+c-di-AMP increased TSdA-specific IgA secretion in the nasal passages and also in the distal intestinal mucosa. Moreover, T and B-lymphocytes from NALT-draining cervical lymph nodes and spleen showed an intense proliferation after ex-vivo stimulation with TSdA. Intranasal administration of TSdA+c-di-AMP provokes an enhancement of TSdA-specific IgG2a and IgG1 plasma antibodies, accompanied by an increase IgG2a/IgG1 ratio, indicative of a Th1-biased profile. In addition, immune plasma derived from TSdA+c-di-AMP vaccinated mice exhibit in-vivo and ex-vivo protective capacity. Lastly, TSdA+c-di-AMP nasal vaccine also promotes intense footpad swelling after local TSdA challenge. Our data support that TSdA+c-di-AMP nasal vaccine triggers a NALT mixed pattern of cytokines that were clearly associated with an evident mucosal and systemic immunogenicity. These data are useful for further understanding the immune responses elicited by the NALT following intranasal immunization and the rational design of TS-based vaccination strategies for prophylaxis against T. cruzi.Fil: Pacini, MarĂa Florencia.

Cost-Effectiveness Analysis for a Heavily Modified Water Body (HMWB): The Lambro-Seveso-Olona System Case Study
The Lambro-Seveso-Olona system (L-S-O) is a effluent dominated watershed which derives from a strong urbanization process of natural river basins. The average population density in the L-S-O area is among the highest in Italy and Europe. Industry is also highly developed. Although at present the L-S-O system does not receive untreated wastewaters, depurated effluents constitute about half of its streamflow. This river has a long history of poor quality status, due to the high concentration of pollutant loads and the poor dilution. Recently new chemical quality standards have been set by the Italian legislation as support for the WFD Good Ecological Status. These standards are very restrictive, and make extremely challenging the achievement of the good ecological status. Aim of this study is to analyse the restoration possibilities of the L-S-O system. Elements are provided for a Cost-Effectiveness analysis
