Synergy between silk fibroin and ionic liquids for active gas-sensing materials.

Silk fibroin is a biobased material with excellent biocompatibility and mechanical properties, but its use in bioelectronics is hampered by the difficult dissolution and low intrinsic conductivity. Some ionic liquids are known to dissolve fibroin but removed after fibroin processing. However, ionic liquids and fibroin can cooperatively give rise to functional materials, and there are untapped opportunities in this combination.

Agreement between muscle mass assessments by computed tomography and calf circumference in patients with cancer: A cross-sectional study.

Background & Aims: Cancer influences body composition, including a loss of muscle mass (MM), associated with worse outcomes. The study aimed to evaluate the agreement between MM estimated by calf circumference (CC) and computed tomography (CT) image as a reference method.

Methods: A cross-sectional study including patients (>20 years) diagnosed with cancer attending a reference center of oncology.

Accuracy of isolated nutrition indicators in diagnosing malnutrition and their prognostic value to predict death in patients with gastric and colorectal cancer: A prospective study.

Background: The study aims to evaluate the accuracy of isolated nutrition indicators in diagnosing malnutrition in patients with gastric and colorectal cancer and their association with mortality.

Methods: Prospective cohort study involving patients with cancer (n = 178) attending a reference center of oncology at any point in the disease trajectory or treatment. Nutrition status was evaluated in a unique moment by body mass index (BMI), Patient-Generated Subjective Global Assessment (PG-SGA), handgrip strength (HGS), and calf circumference (CC).

Low skeletal muscle radiodensity is the best predictor for short-term major surgical complications in gastrointestinal surgical cancer: A cohort study.

The aim of this study was to evaluate whether body composition, muscle function, and their association are predictive factors for short-term postoperative complications in patients with gastric and colorectal cancer. A prospective cohort study was conducted with patients undergoing resection of gastric and colorectal tumors. Nutritional status was assessed using Patient-Generated Subjective Global Assessment (PG-SGA) and anthropometric techniques.

Impact of anterior occlusal conditions in the mixed dentition on oral health-related quality-of-life item levels.

Objectives: To evaluate the impact of anterior occlusal conditions in the mixed dentition on item-level analysis of oral health-related quality of life (OHRQoL).

Materials And Methods: A population-based cross-sectional study of 787 children aged 8 to 10 years was conducted. The Child Perceptions Questionnaire (CPQ8-10) was used to evaluate OHRQoL, and the analysis of item levels was performed on CPQ8-10 domains.

Association between 2 indexes for evaluating malocclusion in the mixed dentition.

Introduction: This study aimed to associate 2 indexes for evaluating malocclusion in the mixed dentition.

Methods: A population-based cross-sectional study was conducted involving 743 children aged 8-10 years, divided into early and late mixed dentition. The Dental Aesthetic Index (DAI) and criteria proposed by Grabowski were used to evaluate malocclusion.

Is perioperative fasting associated with complications, length of hospital stay and mortality among gastric and colorectal cancer patients? A cohort study.

Background: During a surgical procedure, patients are often subjected to fasting for times that are more prolonged than the ideal, which may lead to complications.

Objective: To evaluate the duration of perioperative fasting and its association with postoperative complications, length of hospital stay (LOS) and mortality among gastric and colorectal cancer patients.

Design And Setting: Cohort study developed in a surgical oncology hospital in the city of Natal (Rio Grande do Norte, Brazil).

Low calf circumference is an independent predictor of mortality in cancer patients: A prospective cohort study.

Objective: Loss of muscle mass is associated with worse outcomes in patients with cancer. The objective of this study was to evaluate the prognostic value of calf circumference (CC) and skeletal muscle index from computed tomography (CT) to predict mortality in patients with cancer.

Methods: A single-center prospective study was conducted with patients aged ≥20 y attending a reference center of oncology and who had recent abdominal CT images.

Structural insights into a unique cellulase fold and mechanism of cellulose hydrolysis.

Clostridium thermocellum is a well-characterized cellulose-degrading microorganism. The genome sequence of C. thermocellum encodes a number of proteins that contain type I dockerin domains, which implies that they are components of the cellulose-degrading apparatus, but display no significant sequence similarity to known plant cell wall-degrading enzymes.
