1. Predictive model for difficult laryngoscopy using machine learning: retrospective cohort study
Abstract Background Both predictions and predictors of difficult laryngoscopy are controversial. Machine learning is an excellent alternative method for predicting difficult laryngoscopy. This study aimed to develop and validate practical predictive models for difficult laryngoscopy through machine learning. Methods Variables for the prediction of difficul

2. Analysis of risk factors of abdominal wound dehiscence after radical cystectomy
SUMMARY OBJECTIVE: Wound dehiscence is associated with high morbidity and mortality. This study aimed to analyze the risk factors and comorbidities in the patients undergoing radical cystectomy with early postoperative wound dehiscence. METHODS: In all, 539 patients with bladder cancer who underwent radical cystectomy and urinary diversion at a single cent

3. Nonalcoholic fatty liver disease in women with polycystic ovary syndrome: associated factors and noninvasive fibrosis staging in a single Brazilian center
ABSTRACT Objective Polycystic ovary syndrome (PCOS) is a recognized risk factor for nonalcoholic fatty liver disease (NAFLD). The aims of this study were to investigate the prevalence and factors associated with NAFLD in women with PCOS and evaluate noninvasive indices of hepatic fibrosis in patients with PCOS and NAFLD. Subjects and methods Patients with

4. Structural reliability model considering mixed probabilistic and interval variables
Abstract Traditional probability-based structural reliability analysis method can only consider random uncertainties described by random distribution functions, which required sufficient experimental samples. On comparison, interval uncertainties can be more appropriate when lacking information. In realistic situations, several structural reliability models

5. Aerial biomass allometric models for Prosopis affinis Spreng. in native Espinal forests of Argentina
RESUMO A estimativa do carbono armazenado nos ecossistemas florestais requer ferramentas precisas para prever a biomassa. Objetivou-se nesse estudo determinar a biomassa aérea individual de Prosopis affinis e sua distribuição por componente; desenvolver modelos alométricos para prever a biomassa, e estimar os fatores de expansão da biomassa (FEB) em flo

7. The TNM 8th edition: Validation of the proposal for organ - confined (pT2) prostate cancer
ABSTRACT Purpose: The 8th edition of the TNM has been updated and improved in order to ensure a high degree of clinical relevance. A major change in prostate includes pathologically organ - confined disease to be considered pT2 and no longer subclassified by extent of involvement or laterality. The aim of this study was to validate this major change. Mater

8. Single perineal incision placement of artificial urinary sphincter with cadaveric correlation of sub-dartos pump placement
ABSTRACT Purpose We present a novel AUS implantation technique using a single perineal incision for single device placement or in combination with an inflatable penile prosthesis (IPP). Urinary and sexual dysfunction following the management of prostate cancer has a significant impact on the quality of life of our patients. While there are marginal changes

9. Relationship Among Crop Systems, Soil Cover, and Water Erosion on a Typic Hapludox
ABSTRACT Several soil conservation practices are used to reduce water erosion and ensure sustainable agriculture. An effective crop management practice is intercropping, in which two or more crops with different architectures and vegetative cycles are grown simultaneously in the same area. We hypothesized that intercropping of corn and jack-bean increases so

10. A Classification for a Geostatistical Index of Spatial Dependence
ABSTRACT: In geostatistical studies, spatial dependence can generally be described by means of the semivariogram or, in complementary form, with a single index followed by its categorization to classify the degree of such dependence. The objective of this study was to construct a categorization for the spatial dependence index (SDI) proposed by Seidel and Ol

11. Is It Possible to Classify Topsoil Texture Using a Sensor Located 800 km Away from the Surface?
ABSTRACT It is often difficult for pedologists to “see” topsoils indicating differences in properties such as soil particle size. Satellite images are important for obtaining quick information for large areas. However, mapping extensive areas of bare soil using a single image is difficult since most areas are usually covered by vegetation. Thus, the aim

12. Ultrafast Dynamics of Au Nanopyramid Interfaces Prepared by Nanosphere Lithography: Effect of Substrate Chemical Composition
This work describes ultrafast spectroscopy studies of Au triangular pyramid particle arrays deposited over glass (termed Au/glass), and 190 nm indium tin oxide (ITO) film (termed Au/ITO/glass) prepared by nanosphere lithography. The linear absorption spectra of Au/glass and Au/ITO/glass exhibit surface plasmon resonances at 800 and 870 nm, respectively, in g
