Correlation Between the Friedman Staging System and the Upper Airway Volume in Patients With Obstructive Sleep Apnea

Purpose: This study was designed to evaluate the correlation between computed tomography findings and data from the physical examination and the Friedman Staging System (FSS) in patients with obstructive sleep apnea (OSA). Patients and Methods: We performed a retrospective evaluation by reviewing the medical records of 33 patients (19 male and 14 female patients) with a mean body mass index of 30.38 kg/m 2 and mean age of 49.35 years. Among these patients, 14 presented with severe OSA, 7 had moderate OSA, 7 had mild OSA, and 5 were healthy. Results: The patients were divided into 2 groups according to the FSS: Group A comprised patients with FSS stage I or II, and group B comprised patients with FSS stage III. By use of the Fisher exact test, a positive relationship between the FSS stage and apnea-hypopnea index ( P = .011) and between the FSS stage and body mass index ( P = .012) was found. There was no correlation between age ( P = .55) and gender ( P = .53) with the FSS stage. The analysis of variance test comparing the upper airway volume between the 2 groups showed P =.018. Conclusions: In this sample the FSS and upper airway volume showed an inverse correlation and were useful in analyzing the mechanisms of airway collapse in patients with OSA.

Poder soberano e biopolítica no combate às drogas no Brasil

In the last two or three decades has become common the debate on the harmful effects produced by trade and use of illicit substances in Brazil. The "drug problem" as it became known worldwide in official and media discourses, has become, if not the only, at least the most important determinant of a series of social ills that affect both the rich countries (classified as consumers), and the poor countries (the producers and exporters of these "evil substances"). This situation that today is extremely pernicious, may be better understood through some elements of the story of its constitution. In this sense, we draw a succinct history of drug prohibition worldwide and we use the Foucauldian concept of biopower and the concept of “death policy” designed by André Saldanha Costa to comment briefly on the "drug problem" in Brazil. In this initial approach, we can affirm the importance of these two concepts for the understanding of the “depoliticized life" of drug traffickers as well as the governmental policies, both legal and health focused on this issue.

Lifespan and reproductive dynamics of the commercially important sea bob shrimp Xiphopenaeus kroyeri (Penaeoidea): synthesis of a 5-year study

Population parameters of the shrimp Xiphopenaeus kroyeri (Heller, 1862) (sex ratio, length-frequency distributions (carapace length, CL), growth, lifespan, size of sexual maturity, spawning and recruitment) were analyzed in a long-term study from January 1998 through June 2003. The data on these parameters were collected and analyzed to test the hypothesis that the main period of juvenile recruitment in the bay coincides with the period of fishery closures currently designated by the Brazilian Institute of Environment and Renewable Natural Resources. Monthly collections were conducted along the southeastern Brazilian coast, using a shrimp fishing boat with “double-rig” nets sampling at stations up to 40 m depth. Sex ratios were female-biased only in zones with high reproductive activity such as in stations deeper than 15 m (χ2 test, p<0.05). The mean size of males and females was 15.3 ± 3.1 mm CL and 16.2 ± 4.7 mm CL, respectively, with size at sexual maturity estimates (CL50) of 14.8 mm for males and 15.5 mm for females. Mean growth curves provided estimates of CL∞ = 29.31 mm, k = 0.009/day, t0=−0.25 and CL∞ = 35.33 mm, k = 0.006/day, t0=−0.23 for males and females, respectively, and average lifespans of 1.35 for males and 2.12 years for females. Recruitment and abundances of reproductive females were highly correlated with the environmental factors such as higher water temperature and finer-grained bottom sediment (canonical correlation, r=0.63, p<0.001). The reproductive peaks in February-April 1998, March-May 1999 and February-May 2002 were followed by recruitment peaks in May-July 1998, July-September 1999 and April-June 2002, respectively. Thus, the proposed period of fisheries closure (March to May) does not coincide with the main recruitment periods observed for X. kroyeri.

A banalização da prescrição de psicofármacos em um ambulatório de saúde mental

The development of modern psychiatric medications coupled with the wide range currently gained by preventive emphasis in mental health changed the practices of psychiatry, which is no longer focused on treating insanity but is also dedicated to treat any psychiatric suffering through the prescription of psychopharmacos. This study discusses the current process in which medication has been generalized, and presents the results of an exploratory study aimed to examine the patients' medical files, the trajectory of users since they enter the service to the prescription of psychiatric medication in the scope of a Mental Health Outpatient Clinic, in a town in the west of the São Paulo state, Brazil. Results revealed that most (65%) users already arrive at the service with previous prescription of psychiatric medications, and nearly all (99%) of them receive prescriptions of psychiatric medication once forwarded to psychiatric consultations.

Rykellus anibali n. sp. and Rykellus mineiroi n. sp. are described from adult females and males collected from litter and soil in the state of Sao Paulo, Brazil. A key for the identification of females of the eight recognisable world species of Rykellus is provided.

Two-spotted spider mite and its natural enemies on strawberry grown as protected and unprotected crops in Norway and Brazil

Cultivation of strawberry in plastic tunnels has increased considerably in Norway and in southeastern Brazil, mainly in an attempt to protect the crop from unsuitable climatic factors and some diseases as well as to allow growers to expand the traditional production season. It has been hypothesized that cultivation under tunnels could increase the incidence of one of its major pests in many countries where strawberry is cultivated, including Norway and Brazil, the two spotted spider mite, Tetranychus urticae. The objective of this study was to evaluate the effect of the use of tunnels on the incidence of T. urticae and on its natural enemies on strawberry in two ecologically contrasting regions, Norway (temperate) and southeastern Brazil (subtropical). In both countries, peak densities of T. urticae in tunnels and in the open fields were lower than economic thresholds reported in the literature. Factors determining that systematically seem to be the prevailing relatively low temperature in Norway and high relative humidity in both countries. The levels of occurrence in Norway and Brazil in 2010 were so low that regardless of any potential effect of the use of tunnel, no major differences were observed between the two cropping systems in relation to T. urticae densities. In 2009 in Norway and in 2011 in Brazil, increase in T. urticae population seemed to have been restrained mainly by rainfall in the open field and by predatory mites in the tunnels. Phytoseiids were the most numerous predatory mite group of natural occurrence on strawberry, and the prevalence was higher in Brazil, where the most abundant species on strawberry leaves were Neoseiulus anonymus and Phytoseiulus macropilis. In Norway, the most abundant naturally occurring phytoseiids on strawberry leaves were Typhlodromus (Anthoseius) rhenanus and Typhlodromus (Typhlodromus) pyri. Predatory mites were very rare in the litter samples collected in Norway. Infection rate of the pest by the fungus Neozygites floridana (Neozygitaceae) was low. The results of this work suggest that in Norway the use of tunnels might not affect the population densities of T. urticae on strawberry in years of lower temperatures. When temperature is not a limiting factor for the development of T. urticae in that country (apparently always the case in southern Brazil), strawberry cultivation in the tunnels may allow T. urticae to reach higher population levels than in open fields (because of the provided protection from the direct impact of rainfall), but natural enemies may prevent higher levels from being reached.
