bookPart Isquemia Mesentérica(2013) ZERATI, Antonio Eduardo; WOLOSKER, Nelson- Comparação entre os métodos subjetivo e objetivo para avaliação da capacidade funcional durante tratamento clínico em pacientes com claudicação intermitente(2013) CUCATO, Gabriel Grizzo; ZERATI, Antônio Eduardo; CHEHUEN, Marcel da Rocha; RITTI-DIAS, Raphael Mendes; SAEZ, Glauco; RAGAZZO, Luciana; PUECH-LEÃO, Pedro; WOLOSKER, NelsonOBJECTIVE: To analyze if there is any relation between functional capacity assessed by subjective and objective methods regarding the current state and after clinical treatment in patients with intermittent claudication. METHODS: A total of 500 patients with intermittent claudication were enrolled. All patients underwent clinical examination and a functional evaluation by subjective (clinical visit) and objective method (treadmill test). Additionally, 50 patients were selected to evaluate the effect of clinical treatment by subjective and objective methods in relation to functional capacity. RESULTS: Out of 500 patients, only 60 (12.0%) had similar results in both methods. The remaining, that is 440 patients (88.0%) had subject values in disagreement with stress test findings. Regarding the clinical effect of the treatment on the functional outcomes, results were similar in both methods (χ²=1.7; p=0.427). CONCLUSION: Although the subjective method overestimates the functional capacity when compared to the objective method, no significant differences were observed between both methods when analyzing the effect of clinical treatment. Thus, the subjective method provides similar information as compared with objective method, in monitoring the clinical treatment of patients with intermittent claudication.
- Infection Related to Implantable Central Venous Access Devices in Cancer Patients: Epidemiology and Risk Factors(2013) FREIRE, Maristela P.; PIERROTTI, Ligia C.; ZERATI, Antonio E.; ARAUJO, Pedro H. X. N.; MOTTA-LEAL-FILHO, J. M.; DUARTE, Laiane P. G.; IBRAHIM, Karim Y.; SOUZA, Antonia A. L.; DIZ, Maria P. E.; PEREIRA, Juliana; HOFF, Paulo M.; ABDALA, EdsonOBJECTIVE. To describe the epidemiology of infections related to the use of implantable central venous access devices (CVADs) in cancer patients and to evaluate measures aimed at reducing the rates of such infections. DESIGN. Prospective cohort study. SETTING. Referral hospital for cancer in Sao Paulo, Brazil. PATIENTS. We prospectively evaluated all implantable CVADs employed between January 2009 and December 2011. Inpatients and outpatients were followed until catheter removal, transfer to another facility, or death. METHODS. Outcome measures were bloodstream infection and pocket infection. We also evaluated the effects that the creation of a multidisciplinary team for CVAD care, avoiding in-hospital implantation of CVADs, and limiting CVAD insertion in neutropenic patients have on the rates of such infections. RESULTS. During the study period, 966 CVADs (mostly venous ports) were implanted in 933 patients, for a combined total of 243,792 catheter-days. We identified 184 episodes of infection: 154 (84%) were bloodstream infections, 21 (11%) were pocket infections, and 9 (5%) were surgical site infections. During the study period, the rate of CVAD-related infection dropped from 2.2 to 0.24 per 1,000 catheter-days (P < .001). Multivariate analysis revealed that relevant risk factors for such infection include surgical reintervention, implantation in a neutropenic patient, in-hospital implantation, use of a cuffed catheter, and nonchemotherapy indication for catheter use. CONCLUSIONS. Establishing a multidisciplinary team specifically focused on CVAD care, together with systematic reporting of infections, appears to reduce the rates of infection related to the use of these devices.
- Remote ischemic preconditioning in patients with intermittent claudication(2013) SAES, Glauco Fernandes; ZERATI, Antonio Eduardo; WOLOSKER, Nelson; RAGAZZO, Luciana; ROSOKY, Ruben Miguel Ayzin; RITTI-DIAS, Raphael Mendes; CUCATO, Gabriel Grizzo; CHEHUEN, Marcelo; FARAH, Breno Quintella; PUECH-LEAO, PedroOBJECTIVE: Remote ischemic preconditioning (RIPC) is a phenomenon in which a short period of sub-lethal ischemia in one organ protects against subsequent bouts of ischemia in another organ. We hypothesized that RIPC in patients with intermittent claudication would increase muscle tissue resistance to ischemia, thereby resulting in an increased ability to walk. METHODS: In a claudication clinic, 52 ambulatory patients who presented with complaints of intermittent claudication in the lower limbs associated with an absent or reduced arterial pulse in the symptomatic limb and/or an ankle-brachial index <0.90 were recruited for this study. The patients were randomly divided into three groups (A, B and C). All of the patients underwent two tests on a treadmill according to the Gardener protocol. Group A was tested first without RIPC. Group A was subjected to RIPC prior to the second treadmill test. Group B was subjected to RIPC prior to the first treadmill test and then was subjected to a treadmill test without RIPC. In Group C (control group), both treadmill tests were performed without RIPC. The first and second tests were conducted seven days apart. Brazilian Clinical Trials: RBR-7TF6TM. RESULTS: Group A showed a significant increase in the initial claudication distance in the second test compared to the first test. CONCLUSION: RIPC increased the initial claudication distance in patients with intermittent claudication; however, RIPC did not affect the total walking distance of the patients.
