The reproductive biology of Palythoa caribaeorum (Duchassaing & Michelotti 1860) and Protopalythoa variabilis (Duerden 1898) was studied through monthly samples from tagged colonies from June 1996 to June 1997, in São Sebastião channel, São Paulo, Brazil (45º26'W, 23º50'S). The gametogenesis was similar to that of other zoanthids as shown by histological preparations. Oocyte diameters and maturation stages of testis vesicles were evaluated on squash preparations. Both species showed sequential protogynic hermaphroditism, with high frequency of fertile polyps (83% in P. variabilis and 72% in P. caribaeorum), high frequency of colonies in female sex condition (65.3% of P. variabilis and 41.7% of P. caribaeorum), and apparently continuous gametogenesis. In P. caribaeorum, egg release was continuous and sperm release took place during half of the analyzed period. In P. variabilis, egg and sperm release occurred in April-May and February-March 1997, respectively.

The rainbow runner, Elagatis bipinnulata, which belongs to the Carangidae family, has a circumtropical distribution. It is found throughout the Atlantic Ocean, from Massachusetts (USA) to Bahia (Brazil). The reproductive biology of the rainbow runner was studied, using specimens captured off the São Pedro and São Paulo Archipelago. From July 1999 to November 2003, a total of 352 fishes were analysed (201 females and 151 males). Fork length (FL) was measured and specimens were gutted for gonads collection. In the laboratory, gonads length, width and weight were measured, and sexes identified macroscopically. Through histological analysis, five different maturation stages were identified for females: immature, maturing, mature, spent and resting. A predominance of maturing and mature females was observed from January to May. The highest gonad index (GI) values were also observed during this period, ranging from 7.7 to 55. Mean sexual maturity size (L50) for females was estimated at 64.6 cm (FL). In the studied area the species exhibited total spawning, with two synchronous groups. Testicles were histologically very similar making them impossible to differentiate sexual maturation stages. Considerable variation was observed in the male gonads weight, hampering the assessment of size at maturity. However, GI values for males were also higher from January to May. These results suggest that the spawning period of the rainbow runner in the São Pedro and São Paulo Archipelago occurs during the first semester of the year.

Sensors development and validation for agricultural applications is a relevant research theme. Electromagnetic techniques have been shown to be useful for soil moisture measurement. However, these techniques typically benefit from calibration. In this context, the aim of this study was to calibrate and evaluate the accuracy and precision of the soil moisture measured by two devices with different electromagnetic principles: Frequency Domain Reflectometry (FDR) e High Frequency Soil Impedance (HFSI) in the laboratory with in oxisol. The probes used were Diviner 2000 and Hidrofarm HFM 1010. Soil moisture was measured using both FDR and HFSI probes. A large variation in soil moisture values occurred during the experiment, as it varied from 0.489 m3 m-3 to 0.077 m3 m-3. Both electromagnetic methods showed good correlation compared to the standard method (gravimetric). HFSI probe overestimated the soil moisture values when compared to the gravimetric method, while FDR underestimated the values.   Keywords: capacitance probes, HFSI sensor, FDR sensor, high frequency soil impedance.     SILVA, A.

CALIBRAÇÃO E PRECISÃO DE DOIS MÉTODOS ELETROMAGNÉTICOS DE MEDIÇÃO DE UMIDADE DO SOLO EM OXISOL     2 RESUMO   Medir a umidade do solo com precisão é um importante desafio. O desenvolvimento e validação de sensores para aplicações agrícolas é um tema de pesquisa relevante. As técnicas eletromagnéticas demonstraram ser úteis para a medição da umidade do solo. No entanto, essas técnicas geralmente se beneficiam da calibração. Nesse contexto, o objetivo deste estudo foi calibrar e avaliar a exatidão e precisão da umidade do solo, medida por dois dispositivos com diferentes princípios eletromagnéticos: Reflectometria no Domínio da Frequência (FDR) e Impedância do Solo de Alta Frequência (HFSI) em laboratório em latossolo. As sondas utilizadas foram Diviner 2000 e Hydrofarm HFM 1010. A umidade do solo foi medida usando as sondas FDR e HFSI. Houve uma grande variação nos valores de umidade do solo durante o experimento, de 0,489 m3 m-3 a 0,077 m3 m-3. Ambos os métodos eletromagnéticos mostraram boa correlação em comparação com o método padrão (gravimétrico). A sonda HFSI superestimou os valores de umidade do solo quando comparada ao método gravimétrico, enquanto a FDR subestimou os valores.   Palavras-chave: sondas de capacitância, sensor HFSI, sensor FDR, impedância do solo em alta frequência.

The "Centros de Atenção Psicossocial Infanto-Juvenil" are dispositives of treatment for children and adolescents suffering from severe mental disorders. This article describes sociodemografic characteristics of users of those centers between September 2008 and February 2009 in the state of São Paulo, Brazil. Data from active files randomly selected was collected in 19 Centers in the state of São Paulo. The characteristics analyzed were divided in four groups of variables: identity; living conditions; family structure; schooling and occupation. The results indicated a higher concentration of users between 10 to 14 years-old; prevalence of males; tendency to nuclear and reduced family arrangements (45%); care primarily given by the mother (57%) and high frequency of users attending the regular school (86%). It was possible to identify a well-defined socio demographic profile of users, with differences regarding gender, attending the regular school and/or other institutions, as well as sharing a nuclear family arrangement.

ABSTRACT CONTEXT AND OBJECTIVE: Chronic spinal pain, especially low-back pain and neck pain, is a leading cause of years of life with disability. The aim of the present study was to estimate the prevalence of chronic spinal pain among individuals aged 15 years or older and to identify the factors associated with it. DESIGN AND SETTING: Cross-sectional epidemiological study on a sample of the population of the city of São Paulo. METHOD: Participants were selected using random probabilistic sampling and data were collected via face-to-face interviews. The Hospital Anxiety and Depression Scale (HADS), EuroQol-5D, Alcohol Use Disorders Identification Test (AUDIT), Fagerström test for nicotine dependence and Brazilian economic classification criteria were used. RESULTS: A total of 826 participants were interviewed. The estimated prevalence of chronic spinal pain was 22% (95% confidence interval, CI: 19.3-25.0%). The factors independently associated with chronic spinal pain were: female sex, age 30 years or older, schooling level of four years or less, symptoms compatible with anxiety and high physical exertion during the main occupation. Quality of life and self-rated health scores were significantly worse among individuals with chronic spinal pain. CONCLUSION: The prevalence of chronic spinal pain in this segment of the population of São Paulo was 22.0%. The factors independently associated with chronic pain were: female sex, age 30 years or older, low education, symptoms compatible with anxiety and physical exertion during the main occupation.

A new genus and species of the family Phoxocephalidae is here described with material collected during the Mini Biological Trawl Project at 224 and 500 m depth off Brazil’s southeastern coast in the states of Rio de Janeiro and São Paulo. Atlantiphoxus wajapi n. gen., n. sp. can be grouped in the subfamily Phoxocephalinae and seems to be morphologically close to Fuegiphoxus Barnard and Barnard, 1980 and Parharpinia Stebbing, 1899. However it can be easily distinguished within the phoxocephalids by the following characters: deep pereonites with small coxae; rostrum unconstricted; eyes absent; man­dible molar not triturative, but as a small hump with 3 multicuspidate stout setae; pereopods 3-4 with stout dactylus; pereopod 5 basis strongly tapering distally; pereopod 7 basis anterodistal corner with a row of long plumose setae; dactylus elongate. Epimeral plate 3 posteroventral margin strongly produced.

Eudendrium pocaruquarum , a new species of athecate hydroid referable to the family Eudendriidae, is described from the state of São Paulo, Brazil. The species is very similar to the widespread Eudendrium ramosum (Linnaeus, 1758), differing from it in the smaller size of the large microbasic euryteles. Longstanding problems in the systematics of eudendriid hydroids are noted, and the inadequacies of many early descriptions of species are discussed. The nematocysts provide a supplementary character for discrimination of species of Eudendrium, although information on the cnidome appears to have been sometimes misinterpreted in literature.

CONTEXT AND OBJECTIVESIn Brazil, few studies have investigated the prevalence of potentially inappropriate medications (PIMs) among elderly outpatients. This study aimed to determine the prevalence of PIMs prescribed for elderly outpatients, identify the PIMs most commonly involved, and investigate whether age, sex and number of medications are related to prescription of such medications.DESIGN AND SETTINGObservational descriptive study developed in the Geriatrics Service of the Central Institute of Hospital das Clínicas (HC), Faculdade de Medicina da Universidade de São Paulo (FMUSP), São Paulo, Brazil.METHODSPrescriptions issued to 1,270 elderly patients (≥ 60 years) were gathered from a database. These prescriptions had been written by geriatricians at a tertiary-level university hospital in São Paulo, Brazil, between February and May 2008. The prescriptions were divided according to sex and age group (60-69, 70-79 and ≥ 80). The Beers criteria were used to evaluate PIMs.RESULTSMost of the sample comprised women (77%) and the mean age was 80.1 years. The mean prevalence of PIM prescriptions was 26.9%. Female sex and number of medications prescribed were associated with prescription of PIMs. The chance of having a PIM prescription was lower among patients ≥ 70 years.CONCLUSIONThe greater prevalence of PIMs was correlated with female sex. The chance of having a PIM prescription was lower among patients ≥ 70 years and became greater with increasing numbers of medications prescribed (≥ 7).
