Needle visualization during ultrasound-guided puncture: image optimization.

Background: Obtaining an adequate image of the needle by ultrasound reduces complications resulting from punctures, increasing patient safety and reducing hospitalization costs.

Objectives: To verify human perception in relation to number of pixels, while also identifying the best puncture angle and which needle should be used, and to evaluate whether there is a difference if needle visualization software is used.

Methods: 20 images were analyzed by 103 students who classified them as being sufficient or insufficient and were compared with the quality observed using photoshop.

Sexual Scripts and Sexual Consent: Gender Stereotypes, Music-Media Messages, and Sexual Consent Expectancies Among College Men and Women.

The pervasiveness of sexual assault among college women prompted examination of college students' sexual-consent expectancies using sexual scripting theory as a framework. We aimed to understand how personal beliefs, experiences with sexual violence, and dominant cultural gendered sexual scripts in music media inform sexual-consent expectancies among a sample of primarily White heterosexual college students at a northwestern university ( = 364). Participants viewed music videos with sexual and objectifying content and reported their perceptions of how women were portrayed.

Risk of development of brain metastases according to the IASLC/ATS/ERS lung adenocarcinoma classification in locally advanced and metastatic disease.

Introduction: Brain metastases (BM) are frequent among lung cancer patients, affecting prognosis and quality of life. The International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS) and European Respiratory Society (ERS) lung adenocarcinoma (LADC) classification (IASLC/ATS/ERS) has prognostic impact in early-stage disease; however, its role in the advanced setting is not precise. This study aims to determine the correlation between the predominant histological subtype and the risk of developing brain metastases (BM) in locally advanced and metastatic (stages IIIB-IV) LADC.

Supratracheal laryngectomy: a multi-institutional study.

Introduction: Supratracheal laryngectomy has been described as a surgical procedure for glottic or supraglottic cancer extending to the subglottic region and/or involving the cricoarytenoid joint, aiming to preserve laryngeal function (breathing, phonation and swallowing), without diminishing locoregional cancer control. The choice of supracricoid laryngectomy in these cases could result in a high risk of compromised resection margins.

Objective: To determine the safety, viability, adequacy of surgical margins and the supratracheal laryngectomy results for intermediate and advanced laryngeal cancer by reviewing the results at three different institutions in Brazil.

PlsX deletion impacts fatty acid synthesis and acid adaptation in Streptococcus mutans.

Streptococcus mutans, one of the primary causative agents of dental caries in humans, ferments dietary sugars in the mouth to produce organic acids. These acids lower local pH values, resulting in demineralization of the tooth enamel, leading to caries. To survive acidic environments, Strep.
