The biopsychosocial processes in autism spectrum disorder

Background: Autism is a disorder characterized by pervasive social and communicative impairments, repetitive and stereotyped behaviors and restricted interests. Its causes and effects have been researched from various neurocognitive theoretical perspectives and with the aid of neuroimaging technology. We aimed to describe biopsychosocial processes characteristic of the Autism Spectrum Disorders. Method: Literature review using Medline and Scopus databases published between 2001 and 2011, with the keywords "autism", "theory of mind", "executive functions", "central coherence" and “fMRI”. Results: The studies found were plotted and organized into tables and an explanatory diagram of the main findings was produced. Conclusions: The most popular neurocognitive theories are still unable to fully explain the characteristics of the complications that autistic spectrum disorder causes to the quality of life of individuals living with autism. The association of clinical research and neuroimaging may contribute to a better understanding of the functioning of the brain affected by the disorder.

Visual outcomes and pacient satisfaction follwing implantation of a supplementary multifocal IOL in patients undergoing cataract surgery

Purpose: To assess visual outcomes and patient satisfaction following implantation of the Sulcoflex® multifocal intraocular lens (IOL; Rayner Intraocular Lenses Ltd., Hove, UK) in a procedure combining capsular bag lens implantation with sulcus placement of the Sulcoflex® IOL. Setting: Instituto de Oftalmologia de Assis, Assis, SP, Brazil. Methods: Cataract patients > 45 years, with hyperopia ≥ 1.50 D and potential acuity measurement ≥ 20/30 undergoing Sulcoflex® multifocal IOL implantation were included. Monocular and binocular uncorrected near and distance visual acuity (VA) were evaluated at five days, one month, and three months postoperatively. Contrast sensitivity and refraction were measured in a subset of patients three months postoperatively. Patient satisfaction was assessed one month postoperative. Results: This non-consecutive case series comprised 25 eyes of 13 patients. Eleven eyes (52%) had pre-existing retinal pathologies. Monocular distance VA improved significantly at all follow-up visits. At final follow-up, 88% of eyes had monocular uncorrected distance VA (UDVA) of at least 20/25 and 24% had monocular UDVA of 20/20. All eyes had binocular UDVA of at least 20/25, and 58% had binocular UDVA of 20/20. Monocular uncorrected near vision (UNVA) was J1 in 68% of eyes and all patients had binocular UNVA of J1. Of all eyes studied, 92% and 58% achieved a spherical equivalent within 1 D and −0.5 D, respectively. The majority of patients reported satisfaction with visual outcomes. Complications included a postoperative intraocular pressure spike in four eyes. Conclusion: The Sulcoflex® multifocal IOL improves near and distance VA in cataract patients with retinal abnormalities and good VA potential.

Influence of alloy microstructure on the microshear bond strength of basic alloys to a resin luting cement

The aim of this study was to evaluate the influence of microstructure and composition of basic alloys on their microshear bond strength (µSBS) to resin luting cement. The alloys used were: Supreme Cast-V (SC), Tilite Star (TS), Wiron 99 (W9), VeraBond II (VBII), VeraBond (VB), Remanium (RM) and IPS d.SIGN 30 (IPS). Five wax patterns (13mm in diameter and 4mm height) were invested, and cast in a centrifugal casting machine for each basic alloy. The specimens were embedded in resin, polished with a SiC paper and sandblasted. After cleaning the metal surfaces, six tygon tubes (0.5 mm height and 0.75 mm in diameter) were placed on each alloy surface, the resin cement (Panavia F) was inserted, and the excess was removed before light-curing. After storage (24 h/37°C), the specimens were subjected to µSBS testing (0.5 mm/min). The data were subjected to a one-way repeated measures analysis of variance and Turkey's test (α=0.05). After polishing, their microstructures were revealed with specific conditioners. The highest µSBS (mean/standard deviation in MPa) were observed in the alloys with dendritic structure, eutectic formation or precipitation: VB (30.6/1.7), TS (29.8/0.9), SC (30.6/1.7), with the exception of IPS (31.1/0.9) which showed high µSBS but no eutectic formation. The W9 (28.1/1.5), VBII (25.9/2.0) and RM (25.9/0.9) showed the lowest µSBS and no eutectic formation. It seems that alloys with eutectic formation provide the highest µSBS values when bonded to a light-cured resin luting cement.

Utilização de ácidos nucleicos fetais livres no plasma materno para o diagnóstico pré-natal: realidade do Brasil neste cenário

A descoberta de ácidos nucleicos fetais livres no plasma de gestantes possibilitou o desenvolvimento de novos testes de diagnóstico pré-natal não invasivo para a determinação do sexo e do Rh fetal. Esses testes foram implantados no sistema de saúde pública de diversos países da Europa há mais de cinco anos. As novas possibilidades de aplicação diagnóstica dessas tecnologias são a detecção de aneuploidias cromossômicas fetais, de doenças monogênicas fetais e de distúrbios relacionados com a placenta, temas pesquisados intensivamente por diversos grupos ao redor do mundo. O objetivo deste estudo é expor a situação brasileira no âmbito de pesquisa e utilização clínica dos testes disponíveis comercialmente que utilizam esses marcadores moleculares plasmáticos, ressaltando as vantagens, tanto econômicas quanto de segurança, que os testes não invasivos têm em relação aos atualmente utilizados em nosso sistema de saúde pública.

A pressão por inovação em empresas de base tecnológica, em ciclos cada vez mais curtos e demandando competências complexas, tem levado as empresas à busca de uma estruturação sob a forma de redes de cooperação empresarial, a fim de mitigar riscos e reduzir custos enquanto acelera o time to market. Entretanto, apesar de todas as vantagens e oportunidades reais, há grandes barreiras a serem transpostas. O objetivo dessa pesquisa é compreender o processo de estruturação de uma rede de cooperação no contexto de empresas de base tecnológica. A abordagem metodológica utilizada foi a pesquisa-ação desenvolvida em 30 empresas do setor eletroeletrônico. Os resultados apontam o temor ao comportamento oportunista como o item mais crítico à formação da rede de cooperação empresarial.

Papillary atrophy of the tongue and nutritional status of hospitalized alcoholics

BACKGROUND: Atrophy of the papillae, mucosa, and dorsum of the tongue are considered classical signs of nutritional deficiencies. OBJECTIVE: To assess the nutritional status of hospitalized alcoholics with or without papillary atrophy of the tongue. METHODS: This study was performed with 21 hospitalized alcoholics divided into Atrophic Glossitis Group (n=13) and Normal Tongue Group (n=8). Healthy, non-alcoholic volunteers composed the Control Group (n=8). Anthropometry and bioelectric impedance were performed, and serum vitamins A, E, and B12 were determined. RESULTS: There were no statistical differences in relation to age (46.7±8.7 vs. 46.8±15.8 years) or gender (92.3% vs. 87.5% male), respectively. Control Group volunteers were also paired in relation to age (47.5±3.1 years) and male predominance (62.5%). In relation to hospitalized alcoholics without atrophic lesions of the tongue and Control Group, patients with papillary atrophy showed lower BMI (18.6 ± 2,5 vs 23.8 ± 3.5 vs 26.7 ± 3,6 kg/m² ) and body fat content 7.6 ± 3.5 vs 13.3 ± 6.5 vs 19.5 ± 4,9 kg). When compared with the Control Group, alcoholic patients with or without papillary atrophy of the tongue showed lower values of red blood cells (10.8 ± 2.2 vs 11.8 ± 2.2 vs 14.5 ± 1,6g/dL) and albumin (3.6 ± 0.9 vs 3.6 ± 0.8 vs 4.4 ± 0.2g/dL). The seric levels of vitamins A, E, and B12 were similar amongst the groups. CONCLUSION: Hospitalized alcoholics with papillary atrophy of the tongue had lower BMI and fat body stores than controls, without associated hypovitaminosis.

Phenotypical characterization and adhesin identification in Escherichia coli strains isolated from dogs with urinary tract infections

Pathogenic strains of Escherichia coli are the most common bacteria associated with urinary tract infections in both humans and companion animals. Standard biochemical tests may be useful in demonstrating detailed phenotypical characteristics of these strains. Thirteen strains of E. coli isolated from dogs with UTIs were submitted to biochemical tests, serotyping for O and H antigens and antimicrobial resistance testing. Furthermore, the presence of papC, sfa, and afa genes was evaluated by PCR, and genetic relationships were established using enterobacterial repetitive intergenic consensus PCR (ERIC-PCR). The antimicrobial that showed the highest resistance rate among the isolates was nalidixic acid (76.9%), followed by cephalotin (69.2%), sulfamethoxazole + trimethoprim (61.5%), tetracycline (61.5%), streptomycin (53.8%), ciprofloxacin (53.8%), ampicillin (46.2%), gentamicin (30.8%) and chloramphenicol (23.1%). No isolate was resistant either to meropenem or nitrofurantoin. Among the five clusters that were identified using ERIC-PCR, one cluster (A) had only one strain, which belonged to a serotype with zoonotic potential (O6:H31) and showed the genes papC+, sfa+, afa-. Strains with the genes papC-, sfa+, afa- were found in two other clusters (C and D), whereas all strains in clusters B and E possessed papC-, sfa-, afa- genes. Sucrose and raffinose phenotypic tests showed some ability in discriminating clusters A, B and C from clusters D and E.
