Methods: This was a cross-sectional study involving patients with clinically stable CF patients (16 years of age or older). The patients underwent clinical assessment, nutritional assessments, pulmonary function tests, and pancreatic function assessment. They also completed a questionnaire regarding diet compliance. On the basis of their nutritional status, the patients were classified divided into three groups: adequate nutrition; at nutritional risk; and malnutrition. Results: The study has included 73 patients (mean age, 25.6 ± 7.3 years), 40 of whom (54.8%) were female. The mean body mass index was 21.0 ± 3.0 kg/m2 and the mean FEV1 was 59.7 ± 30.6% of predicted. In this sample of patients, 32 (43.8%), 23 (31.5%), and 18 (24.7%) of the patients were allocated to ...

We searched major databases up to June 2022 to include studies that used artificial intelligence to diagnose lung cancer, using the histopathological analysis of true positive cases as a reference. The quality of the included studies was assessed independently by two authors based on the revised Quality Assessment of Diagnostic Accuracy Studies. Six studies were included in the analysis. The pooled sensitivity and specificity were 0.93 (95% CI 0.85–0.98) and 0.68 (95% CI 0.49–0.84), respectively. Despite the significantly high heterogeneity for sensitivity (I2 = 94%, p < 0.01) and specificity (I2 = 99%, p < 0.01), most of it was attributed to the threshold effect. The pooled SROC curve with a bivariate approach yielded an area under the curve (AUC) of 0.90 (95% CI 0.86 to 0.92). The DOR for the studies was 26.7 (95% CI 19.7–36.2...

Objetivos: avaliar a relacao entre o estado nutricional e a percepcao da imagem corporal entre os trabalhadores de Porto Alegre, Brasil. Materiais e Metodos: Estudo transversal com 203 carteiros. As variaveis antropometricas avaliadas foram peso, estatura, circunferencia da cintura (CC) e do pescoco (CP). A percepcao da imagem corporal foi avaliada atraves da Silhouette Matching Task desenvolvida por Stunkard, adaptada por Mash e Roche. Resultados: Os carteiros foram recrutados entre 2011 e 2013, na cidade de Porto Alegre. A media de idade foi de 41 ± 11,3 anos, 74 (36,4%) individuos eram eutroficos, 85 (41,9%), tinham sobrepeso, e 44 (21,7%), eram obesos. Quanto a CC, 115 (76,2%) homens e 22 (42,3%) mulheres foram classificados como adequados. Ja quanto a CP, 82,8% dos homens e 65,8% das mulheres apresentaram valores acima dos recomendados. Em r...
