Background: Fast-track worldwide reperfusion programs improve outcomes in ST-elevation myocardial infarction and stroke. Similar programs called Program Evaluation and Review Technique (PERT) focus on submassive and massive pulmonary embolism (PE) excluding deep venous thrombosis (DVT). Methods: PREVENTION-team (Hospital Zambrano Hellion Venous Thromboembolism [VTE] Rapid Response). Primary objective: diagnostics, to improve proximal DVT and submassive and massive PE patients care. Secondary objectives: Increase diagnosis rate of low-risk PE and distal DVT; exploration of cause; long-term anticoagulation; identify high-risk profile for chronic complications; community-based support groups and patient education to extend the concept of the thrombosis-free hospital to thrombosis-free home. Structure and organization: The team includes cardiologists, vascular medicine, angiologist, echocardiographer, cardiovascular imaging, and interventional cardiologists. The team will be accessible 24 h a day, 7 days a week, 365 days a year, and base on previous national experience. The cardiology fellow on call will be responsible for activation and evaluation. We will design several tools to accelerate these processes. Risk stratification and therapeutic approach will be based on clinical presentation, echocardiogram, and biomarkers findings. According to PERT stratification based on resources and medical specialties, Hospital Zambrano Hellion has level 1 PERT. PREVENTION-team links physicians with different expertise, provide fast, efficient, and time-saving treatment, potentially saving lives and reducing bleeding and chronic complications in VTE patients. Finally, establishing a network in our hospital and health system to improve VTE patients care. To the best of our knowledge, this is the first rapid response team focused on VTE in Mexico.

Maintaining and increasing production are the main challenges for oil and gas companies in today's difficult market. To achieve these goals, these companies are looking for new techniques to improve fracture characterization. Open natural fractures, when present, can provide the conduit for the majority of natural gas in low porosity, hard rock environments. Therefore, a complete understanding of fracture attributes is required for optimal production, as well as cementing and completion design, well placement, and reservoir modeling.In the La Paz field in Venezuela, previous petrophysical interpretation assumed the cementation exponent, m to be equal to 2. This assumption was made due to the absence of special core analysis and logging information such as dipolar sonic and micro resistivity image logs, increasing the uncertainty in the petrophysical model.Using the crossplot of Ø vs. Rt on log log coordinates it was possible to determine the cement exponent, m, value for each zone. This parameter was fundamental to the estimation of the fracture and matrix porosity, fracture Intensity Index, and the Partitioning Coefficient.The methodology applied in this case study is based on advanced acoustic analysis integrated with triple combo and borehole micro resistivity images. The triple combo (gamma ray, induction resistivity, neutron and density) and the image data allowed identification of the natural fractures, and the Stoneley wave analysis confirmed that several of the fractures observed in the borehole image data were open.This methodology reduced the fracture characterization uncertainty of the La Paz Field and helped to more accurately estimate petrophysical properties where special core data is not available.
