The objective of this study is to report on the colonization of palm trees
by Rhodnius neglectus, its invasion in an urban area, in Araçatuba -
São Paulo, and the control and surveillance measures that have been put in place.
Domiciliary triatomine searches occurred in apartments upon the inhabitants''
notification. The collected insects were identified and examined for natural
infection and food sources with a precipitin test. To search the palm trees, tarps
were used to cover the floor, and a “Munck” truck equipped with a tree-pruning device
was utilized. Chemical control was performed with the utilization of a manual
compression. In 2009, 81 specimens of Rhodnius neglectus were
collected from the domiciles by the population. The precipitin test revealed a
presence of human blood in 2.7% of the samples. Entomological studies were carried
out in these domiciles and in those located within a radius of 200 meters. The search
performed in the palm trees resulted in the capture of 882 specimens of triatomines,
negative for tripanosomatids. Mechanical and chemical controls were carried out. New
searches conducted in the palm trees in the same year resulted in the capture of six
specimens. The mechanical and chemical controls of the palm trees, together with the
population''s work, proved to be effective, therefore preventing these insects''
colonization of the city''s domiciles. 相似文献

Background
Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used.Objective
To determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them.Methods
Cross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria.Results
Prevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good.Conclusion
Prevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others. 相似文献43.
Background
The utility of screening for venous thromboembolism (VTE) in cancer patients is unknown. We evaluated this in a prospective cohort study of cancer patients initiating a new chemotherapy regimen and deemed high-risk (score ≥ 3) based on a validated Risk Score.Methods
Patients were evaluated with baseline and Q4 (± 1) week serial ultrasonography for up to 16 weeks; additionally, computed tomography scans for restaging were also evaluated for VTE.Results
The study population comprised 35 patients. Pancreatic and gastro-esophageal cancers were the most common diagnoses. Of these, 8 (23%) developed a VTE. This included 5 patients with DVT alone (14%), 1 patient with PE alone (3%) and 2 (6%) with both. Ultrasound examinations identified asymptomatic DVT in 9.3% of patients at baseline; 0% at weeks 4 and 8 and 5.6% at week 12. Restaging CT scans identified asymptomatic PE in one patient at week 6 and in one patient at week 9 with subsequent DVT at week 10.Conclusions
Screening for asymptomatic VTE has not been previously used as a clinical strategy in ambulatory cancer patients. We report that one-tenth of patients at baseline had occult DVT and in this high-risk population, screening at baseline may be of value. 相似文献44.

Abstract Background. The aim of this study is to critically evaluate the bond strength (BS) of Glass-Ionomer Cements (GIC) to dentine with microtensile (μTBS) and microshear (μSBS) BS tests by assessing their rankings and failure patterns. Methods. Samples were made on flat dentine surfaces and submitted to μTBS and μSBS. The materials used were: high viscosity GIC (Ketac(?) Molar Aplicap-KM), resin-modified GIC (Fuji II-FII), nano-filled resin-modified GIC (Ketac(?) N100-N100) and an etch-and-rinse adhesive system with a composite resin (Adper(?) Single Bond 2 and Z100(?)-Z100). All tests were performed with a Universal Testing Machine (24 h water storage, crosshead speed of 1 mm/min). Debonded surfaces were examined with a stereomicroscope (×40) to identify the failure mode. The data was analyzed with two-way ANOVA (p < 0.05) and LSD test. Results. Means were statistically different regarding the tests and materials, indicating that values for BS obtained for each material depend on the test performed. Failure analysis revealed that failures produced by μTBS were mainly cohesive for KM and FII. μSBS failures were mainly adhesive or mixed for all materials. For the μTBS, the rank was Z100 > FII > KM = N100, whereas for the μSBS it was Z100 = FII = KM > N100. Conclusion: It may be concluded that distinct micro-mechanical tests present different failure patterns and rankings depending on the material to be considered. 相似文献

Purpose
In in vitro maturation (IVM) cycles primed with human chorionic gonadotropin (hCG), both immature and mature oocytes are retrieved from antral follicles sized 8–12 mm. Using time-lapse microscopy, we compared the morphokinetic behavior of embryos developed from oocytes matured in vivo and in vitro, testing the hypothesis that IVM affects preimplantation development. Furthermore, we extended the morphokinetic analysis of these embryos by a comparison with embryos obtained in stimulated assisted reproduction technology (ART) cycles.Methods
In IVM cycles primed with follicle-stimulating hormone (FSH)/hCG, prior to sperm microinjection, oocytes surrounded by an expanded cumulus at retrieval and presumably mature (EC-MII) were incubated for 6 h, while immature oocytes enclosed in a compact cumulus (CC) were matured in vitro for 30 h. The morphokinetics of embryos selected for transfer or cryopreservation, derived from EC-MII and CC oocytes, were comparatively and retrospectively analyzed in terms of cleavage times (t2, t3, t4, t5, and t8) and intervals (cc2, cc3, s2, s3). For further comparison, the morphokinetics of embryos selected for transfer or cryopreservation (ICSI) or giving rise to ongoing pregnancies (model) in stimulated ART cycles was also assessed.Results
The morphokinetic behavior of EC-MII and CC embryos was entirely comparable, as suggested by the absence of statistical differences in the averages of all cleavage times and intervals. Almost all cleavage and interval times were also similar between EC-MII, CC, ICSI, and model groups, with the exception of t4 and s2, which were delayed and longer, respectively, in embryos generated in IVM cycles (EC-MII and CC).Conclusions
These findings do not support the hypothesis that maturation in vitro affects embryo morphokinetics, while they suggest only marginal differences in the morphokinetics of embryos developed from oocytes matured in vivo and in vitro in IVM cycles and embryos developed from mature oocytes recovered in stimulated cycles.49.
Patients with coronary disease and related health care providers are faced with confusing and often conflicting information with regards to the neurocognitive impact of different strategies for coronary revascularization. Studies involving the measurement of postoperative cognitive deficit (POCD) have significant limitations that may ultimately impact on their interpretation and clinical relevance. In this review, we have described the origin of these tests and delineated the rationale for the design of testing that is commonly used in cardiac surgery patients. In general, neurocognitive tests assess domains of memory/new learning, psychomotor speed/dexterity and attentional capacity/mental control. Pre- and post-intervention tests in each domain can be evaluated either by the measurement of mean change scores (Group Comparison Model) for the entire group as continuous data, or by using categorical or continuous data to examine patterns of individual decline (Individual Comparison Model). This latter approach requires a specific definition of what constitutes a decline, which can be criticized as being arbitrary. There are limitations to each of these approaches that necessitate that critical information in trial design is available to the reviewer to facilitate interpretation. For example, the impact of factors such as test/re-test reliability and practice effect can be mitigated by the use of an appropriately chosen control population. Liberal parlance of neurocognitive outcome as a rationale for therapeutic choice must be tempered by wise interpretation of these tests. It is only through the understanding of their limitations and the implications of trial design that we can translate these results to provide the best therapeutic options for our patients in unbiased manner. 相似文献

This paper presents a mixed-integer model predictive controller for walking. In the proposed scheme, mixed-integer quadratic programs (MIQP) are solved online to simultaneously decide center of mass jerks, footsteps positions, durations, and rotations while respecting actuation, geometry, and contact constraints. Most walking controllers require preplanned footstep rotations to avoid dealing with the nonlinearity introduced by foot rotation decision. The main contribution of this work is an optimization formulation where feet rotations are automatically planned to attain a reference speed rotation. Finally, simulation results are shown to present and discuss the capabilities of the proposed formulation. 相似文献
