ABSTRACT
OBJECTIVE: to compare the effectiveness of two educational interventions used by a healthcare provider in the monitoring of individuals with type 2 diabetes mellitus (T2DM), regarding knowledge of the disease, impact on quality of life and adoption of self-care actions. METHODS: comparative, longitudinal, prospective study performed with 150 subjects with type 2 diabetes, analyzed according to the type of participation in the program (individual and/or group). Participants of the individual intervention (II) received nursing consultations every six months and those of the group intervention (GI) took part in weekly meetings for three months. Data were collected through four questionnaires: Identification questionnaire, Problem Areas in Diabetes Questionnaire (PAID), Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) and the Diabetes Knowledge Scale (DKN-A). Data were analyzed using the Friedman and Mann Whitney tests, considering a statistical significance of p ≤ 0.05. RESULTS: there was an increase in knowledge about the disease in the II (p<0.003) and GI (p<0.007), with reduction of the impact on the quality of life in the II (p<0.007) and improvement in self-care actions in the GI (p<0.001). CONCLUSION: in both intervention models improvements were observed in the indicators, over the six month monitoring period. .
OBJETIVO: comparar a efetividade de duas intervenções educativas, utilizadas por uma operadora de saúde, no acompanhamento ao indivíduo com diabetes mellitus Tipo 2 (DM2), quanto ao conhecimento sobre a doença, impacto na qualidade de vida e adoção de ações de autocuidado. MÉTODOS: estudo comparativo, longitudinal, prospectivo, realizado com 150 indivíduos com diabetes tipo 2, analisados conforme a modalidade de participação no programa (individual e/ou em grupo). Os participantes da intervenção individual (II) realizaram consultas de enfermagem a cada seis meses e os da intervenção em grupo (IG), reuniões semanais por três meses. Os dados foram coletados mediante quatro questionários: Questionário de identificação, Questionário de Impacto na Qualidade de Vida em Diabetes (PAID), Questionário de Autocuidado em Diabetes (QAD) e Questionário de Conhecimento do Diabetes (DKN-A). Os dados foram analisados utilizando-se o Teste de Friedman e o Teste de Mann Whitney, considerando significância estatística para p ≤ 0,05. RESULTADOS: verificou-se aumento do conhecimento sobre a doença na II (p<0,003) e na IG (p<0,007), redução do impacto na qualidade de vida na II (p<0,007) e melhora das ações de autocuidado na IG (p<0,001). CONCLUSÃO: em ambos os modelos de intervenção foram observadas melhoras dos indicadores, ao longo dos seis meses de acompanhamento. .

Los datos fueron recolectados mediante cuatro cuestionarios: Cuestionario de identificación, Cuestionario de Impacto en la Calidad de Vida en Diabetes (PAID), Cuestionario de Autocuidado en Diabetes (CAD) y Cuestionario de Conocimiento de la Diabetes (DKN-A). Los datos fueron analizados utilizando el test de Friedman y el test de Mann Whitney, considerando significación estadística para p ≤ 0,05. RESULTADOS: se verificó aumento del conocimiento sobre la enfermedad en la II (p<0,003) y en la IG (p<0,007), reducción del impacto en la calidad de vida en la II (p<0,007) y mejoría de las acciones de autocuidado en la IG (p<0,001).

BACKGROUND/AIMS: Few studies have assessed the prognostic value of the primary tumor maximum standardized uptake value (SUVmax) measured by 2-[18F]-fluoro-2-deoxy-D-glucose PET-CT for patients with bile duct and gallbladder cancer. METHODS: A retrospective analysis of 61 patients with confirmed bile duct and gallbladder cancer who underwent FDG PET-CT in Kangbuk Samsung Medical Center (Seoul, Korea) from April 2008 to April 2011. Prognostic significance of SUVmax and other clinicopathological variables was assessed. RESULTS: Twenty-three patients were diagnosed as common bile duct cancer, 17 as hilar bile duct cancer, 12 as intrahepatic bile duct cancer, and nine as gallbladder cancer. In univariate analysis, diagnosis of intrahepatic cholangiocarcinoma and gallbladder cancer, mass forming type, poorly differentiated cell type, nonsurgical treatment, advanced American Joint Committee on Cancer (AJCC) staging and primary tumor SUVmax were significant predictors of poor overall survival. In multivariate analysis adjusted for age and sex, primary tumor SUVmax (hazard ratio [HR], 4.526; 95% CI, 1.813-11.299), advanced AJCC staging (HR, 4.843; 95% CI, 1.760-13.328), and nonsurgical treatment (HR, 6.029; 95% CI, 1.989-18.271) were independently associated with poor overall survival. CONCLUSIONS: Primary tumor SUVmax measured by FDG PET-CT is an independent and significant prognostic factor for overall survival in bile duct and gallbladder cancer.

Parkinsons disease (PD) is a common neurodegenerative disorder that is mainly caused by dopaminergic neuron loss in the substantia nigra. Several nuclear medicine radiotracers have been developed to evaluate PD diagnoses and disease evolution in vivo in PD patients. Positron emission tomography (PET) and single photon computerized emission tomography (SPECT) radiotracers for the dopamine transporter (DAT) provide good markers for the integrity of the presynaptic dopaminergic system affected in PD. Over the last decade, radiotracers suitable for imaging the DAT have been the subject of most efforts. In this review, we provide a critical discussion on the utility of DAT imaging for ParkinsonÆs disease diagnosis (sensitivity and specificity).
A doença de Parkinson (DP) é uma desordem neurodegenerativa causada por perda de neurônios dopaminérgicos na substância negra. Vários traçadores da medicina nuclear têm sido desenvolvidos para avaliar o diagnóstico e acompanhamento da DP. Traçadores para o transportador de dopamina (TDA) utilizados na tomografia por emissão de pósitrons (PET) e tomografia por emissão de fóton único (SPECT) demonstram boa marcação na integridade de sistema dopaminergico pré-sináptico, afetada na DP. Na última década, radiotraçadores apropriados para imagens de TDA têm sido mais estudados. Nesta revisão, provemos uma discussão crítica sobre a utilidade dessas imagens de TDA para o diagnóstico de DP (sensibilidade e especificidade).

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of [i] unwanted patient motion, as well as motions due to [ii] cardiac and [iii] respiratory cycles. For the first type of motion [most often studies in PET brain imaging], conventional motion-correction algorithms have relied on extraction of the motion information from the emission data itself. However, the accuracy of motion compensation in this approach is degraded by the noisy nature of the emission data. Subsequently, advanced methods, as reviewed in this work, make use of external real-time measurements of motion. Various image-based and projection-based correction methods have been discussed and compared. The paper also reviews recent and novel applications that perform corrections for cardiac and respiratory motions. Unlike conventional gating schemes, in which the cardiac and respiratory gated frames are independently reconstructed [resulting in noisy images], the reviewed methods are seen to follow a common trend of seeking to produce images of higher quality by making collective use of all the gated frames [and the estimated motion]. As an observation, a general theme in motion-correction methods is seen to be the use of increasingly sophisticated software to make use of existing advanced hardware. In this sense, this field is very open to future novel ideas [hardware, and especially software] aimed at improving motion detection, characterization and compensation
