La calidad de vida de las madres de niños trabajadores en las calles de São Paulo, Brasil

The present study evaluated the perceived quality of life of the mothers of street children and investigated the association with their history of childhood violence, the occurrence of current domestic violence, their current mental states and that of their children, and family functioning. the applied instruments were as follows: Strengths and Difficulties Questionnaire, WorldSAFECore Questionnaire, Instrument for the Assessment of Quality of Life of the WHO, Global Assessment of Relational Functioning Scale, Childhood Trauma Questionnaire and a socio-demographic questionnaire. the sample of convenience consisted of 79 low-income mothers who raised their children alone, and most of whom had a positive screening for mental illness. the multiple regression analysis showed that the perception of quality of life of these women was associated with the presence of psychopathology either in themselves or their children and family dysfunction. Thus any program aimed at improving the quality of life of such mothers should consider addressing their mental problems as well as those of their children, besides offering educational and psychotherapeutic approaches to these families to improve the social environment.Universidade Federal de São Paulo, Dept Psiquiatria, BR-04038020 São Paulo, SP, BrazilUniv São Paulo, Inst Matemat & Estat, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Psiquiatria, BR-04038020 São Paulo, SP, BrazilWeb of Scienc

Validation of the Brazilian-Portuguese version of the Clinician Administered Post Traumatic Stress Disorder Scale-5

Objectives: The aim of this study was to validate CAPS-5 for the Brazilian-Portuguese language on a sample of 128 individuals from two centers (from the cities of São Paulo and Porto Alegre) who have been recently exposed to a traumatic event. Methods: We performed a reliability analysis between interviewers (with a subset of 32 individuals), an internal consistency analysis, and a confirmatory factorial analysis for the validation study. Results: The inter-rater reliability of the total PTSD symptom severity score was high [intraclass correlation coefficient =0.994, 95% CI (0.987–0.997), p < 0.001]. Cohen’s Kappa for individual items ranged between 0.759 and 1. Cronbach’s alpha coefficients indicated high internal consistency for the CAPS-5 full scale (α = 0.826) and an acceptable level of internal consistency for the four symptom clusters. The confirmatory factorial analysis for the 20-item original CAPS-5 did not fit the data well. A 15-item model with better results was then established by excluding the following CAPS-5 items: dissociative amnesia, recklessness, distorted cognitions, irritability, and hypervigilance. Conclusion: Despite the limitation of the predominance of female victims, and the high number of sexually assaulted women in our sample, the model with only 15 items provided a good fit to the data with high internal consistency (α = 0.835)

Tumor de Frantz em paciente do sexo feminino com diarreia: relato de caso de neoplasia pancreática rara

O tumor pseudopapilar sólido, também conhecido como tumor de Frantz, é um tumor raro do pâncreas. Relatamos o caso de uma paciente de 25 anos com dor abdominal, febre, diarréia e perda de peso.TC de abdome com contraste revelou pâncreas alargado com lesão hipodensa de aparência nodular e calcificações periféricas. Foi decidido realizar pancreatectomia subtotal com linfadenectomia e optou-se pela esplenectomia com biópsia hepática intra-operatória. O anatomopatológico da ressecção cirúrgica do tumor pancreático revelou tumor pseudopapilar sólido compatível com o tumor de Frantz. A imuno-histoquímica confirmou os achados histopatológicos. Ela evoluiu com fístula pancreática e pancreatite resolvida após 15 dias. Atualmente, está sendo acompanhada ambulatorialmente em nosso serviço com remissão completa dos sintomas.Solid pseudopapillary tumor, also known as frantz tumor, is a rare tumor of the pancreas. We report a case of 25-year-old female patient with abdominal pain, fever, diarrhea and weight loss. Contrast abdominal CT showed enlarged pancreas with a hypodense lesion of nodular appearance and peripheral calcifications.It was decided to perform subtotal pancreatectomy with lymphadenectomy, and opted for splenectomy and intraoperative liver biopsy. The pathology of surgical resection of the pancreatic tumor showed solid pseudopapillary tumor compatible with Frantz’s tumor. Immunohistochemistry confirmed histopathological findings. She evolved with pancreatic fistula and pancreatitis resolved after 15 days. Currently, it is being followed up in our service with complete remission of symptoms

Implicações da radiação na saúde dos profissionais que utilizam a fluoroscopia na prática diária: Implications of radiation on the health of professionals who use the fluoroscopy in daily practice

O presente estudo tem como objetivo analisar as implicações da radiação na saúde dos profissionais que utilizam o arco cirúrgico na prática diária. Neste estudo foi realizada uma revisão sistemática da literatura. Para seleção das publicações foram considerados como critérios de inclusão estar disponível em formato completo, publicado nos últimos cinco anos (2018-2022), escritas em língua portuguesa e inglesa. E como critérios de exclusão foram considerados estar foram do tema de pesquisa, ser revisão de literatura e repetido na base de dados. Os critérios de inclusão e exclusão foram considerados como meio de validade metodológica. Concluiu-se a partir desse estudo que apesar de baixos níveis de radiação emitidos por arco cirúrgico, os riscos ainda são significativos, verificando-se a necessidade de conscientização dos profissionais de saúde sobre a proteção necessária para mitigação das implicações, principalmente, entre os menos experientes.&nbsp

MOS Capacitance Measurements for PEALD TiO2 Dielectric Films Grown under Different Conditions and the Impact of Al2O3 Partial-Monolayer Insertion

In this paper, we report the plasma-enhanced atomic layer deposition (PEALD) of TiO2 and TiO2/Al2O3 nanolaminate films on p-Si(100) to fabricate metal-oxide-semiconductor (MOS) capacitors. In the PEALD process, we used titanium tetraisopropoxide (TTIP) as a titanium precursor, trimethyl aluminum (TMA) as an aluminum precursor and O2 plasma as an oxidant, keeping the process temperature at 250 &deg;C. The effects of PEALD process parameters, such as RF power, substrate exposure mode (direct or remote plasma exposure) and Al2O3 partial-monolayer insertion (generating a nanolaminate structure) on the physical and chemical properties of the TiO2 films were investigated by Rutherford backscattering spectroscopy (RBS), Raman spectroscopy, grazing incidence X-ray diffraction (GIXRD), and field emission scanning electron microscopy (FESEM) techniques. The MOS capacitor structures were fabricated by evaporation of Al gates through mechanical mask on PEALD TiO2 thin film, followed by evaporation of an Al layer on the back side of the Si substrate. The capacitors were characterized by current density-voltage (J-V), capacitance-voltage (C-V) and conductance-voltage (G-V) measurements. Our results indicate that RF power and exposure mode promoted significant modifications on the characteristics of the PEALD TiO2 films, while the insertion of Al2O3 partial monolayers allows the synthesis of TiO2/Al2O3 nanolaminate with well-spaced crystalline TiO2 grains in an amorphous structure. The electrical characterization of the MOS structures evidenced a significant leakage current in the accumulation region in the PEALD TiO2 films, which could be reduced by the addition of partial-monolayers of Al2O3 in the bulk of TiO2 films or by reducing RF power
