Abstract: to assess fluid responsiveness in patients under spontaneous breathing activity ventilation remains a challenge for intensive care physicians. much of the knowledge on heart-lung interactions and dynamic indexes of fluid responsiveness may not be useful for these patients. historically, the most frequently used variables to guide fluid responsiveness on this population have been the static preload indexes. however, more recently, dynamic indexes from less invasive devices are being often used, even though their usefulness on spontaneously-breathing subjects remains controversial. the purpose of this article was to review evidences on the assessment of fluid responsiveness in patients under spontaneous ventilation. a search in literature showed poor evidence for use of static variables, such as filling pressures and ventricular end-diastolic volumes. dynamic indexes, such as pulse pressure variation and other indexes had not been appropriately tested during spontaneous ventilation. favorable results were found with central venous pressure variation and with transthoracic echocardiography or transesophageal doppler dynamic indexes, especially when associated to passive lower limb elevation. we conclude that although central venous pressure variation and echocardiography variables could aid bedside clinicians in assessing fluid responsiveness during spontaneous ventilation, more studies on this subject are definitely required.

Abstract: the susceptibility of aedes aegypti to temefos was evaluated by means of samples of eggs and larvae from four large counties in the state of ceará (fortaleza, barbalha, juazeiro do norte and crato). the technique standardized by the world health organization for tests with larvicides was used. the cl50 of eight samples from populations of aedes was determined, as were their respective resistance ratios, compared to the cl50 of the susceptible rockefeller strain. all populations submitted to the experiment showed resistance to temefos, with resistance ratios varying between 8 and 16. analysis of these results reinforces prior evidence regarding the dissemination of temefos resistance in different locations in the state, subjected to considerable pressure for control in recent decades. the larvicide may lose its effectiveness if an urgent attempt is not made to reestablish the susceptibility of aedes aegypti in these areas, profoundly affecting control campaigns currently under way.

Abstract: objective: to evaluate the effectiveness of adding vildagliptin to the treatment of patients with inadequately controlled type 2 diabetes mellitus (t2dm) treated with a combination of metformin and a sulphonylurea. subjects and methods: 37 t2dm patients with hba1c ranging from 7.7% to 12.4% (mean of 9.30 ± 1.38), despite the use of metformin in combination with a sulphonylurea, were additionally treated with vildagliptin (100 mg/day) for at least 6 months. results: during triple oral therapy (tot) hba1c levels < 7% were achieved in 11 patients (29.7%), whereas levels of fasting plasma glucose (fpg) < 120 mg/dl were observed in 12 patients (32.4%). both findings were observed in 10 patients (27.0%). compared to nonresponsive subjects, lower mean baseline hba1c and fpg levels were seen in responsive patients, but the difference was only statistically significant for fasting plasma glucose (fpg). moreover, there was considerable overlap between the two groups. conlusion: our preliminary results suggest that tot with metformin, a sulphonylurea and vildagliptin may be useful for some t2dm patients nonresponsive to combination therapy with metformin and sulphonylurea.

Abstract: objective: to evaluate the efficacy of fish as predators of the aedes aegypti larvae in laboratory conditions. methods: the male and female of five different fish were included in the experiment. the tests to measure their consumption ability lasted five weeks for each species. each trial involved four test tanks and four control tanks. two control tanks contained just one fish, and the other two just larvae. each of the test tanks contained one fish and the larvae. during the first week, 100 larvae were placed in the tank, with an additional 100 added every week, up to a maximum daily amount of 500 larvae. the length and weight of the fish were measured at the beginning and end of every week. results: a total of 369,000 larvae were used. the trichogaster trichopteros was the only species in which both sexes ate 100% of the available larvae. the betta splendens failed to eat only 15 larvae. the male poecilia reticulate showed a strong capacity for larvae eating, compared with the female of the same species. in terms of weight and size, the betta splendens proved capable of eating 523 larvae per gram of weight per day. conclusions: the female and male trichogaster trichopteros and astyanax fasciatus, and the female betta splendens and poecilia sphenops proved to be the most effective predators of the aedes aegypti larvae. and although the male poecilia sphenops and female poecilia reticulata were less effective, they were also capable of eradicating the total number of aedes aegypti larvae that could appear over 24 hours in a breeding site under natural conditions. the male poecilia reticulata, however, proved incapable of doing so.

Abstract: the study of a measles epidemic in the ribeir?o preto region, in 1984, showed a high proportion of cases occurring among people above 15 years of age. this finding hed to the identification of a particular characteristic of the disease's distribution in the area, i.e. the high incidence among rural workers (especially those restricted to colletive lodgings when working in agricultural and industrial activities related to sugar cane plantations). a methodological exercise of synthesis between the descriptive phase of the traditional epidemiology and the was carried out. this producere aimed at incorporating some aspects of the social process of the area with a view to explaining this particular distribution of measles as a result to that social process (i.e. the pattern of the occurrence of measles among rural workers is understood as a historically determined social event). finally, the need to consider the appearance of specific diseases in different human groups according to the social process into whick they are inserted in disenssed in such a way that their historicity and specificity are taken into account.
