Exploring the dynamics of ultrasound training in medical education: current trends, debates, and approaches to didactics and hands-on learning.

Introduction: Medical education, especially in ultrasound training, is undergoing significant changes. This study examines practical issues in ultrasound medical education, emphasizing state-of-the-art teaching methods, their effectiveness, and implementation challenges.

Methods: The study analyzed advancements in ultrasound education, including randomized controlled trials comparing peer-to-peer teaching with traditional faculty-led instruction.

Sucrose monolaurate production from lauric acid through a two-stage process.

This work represented the first step toward pioneering the use of a two-stage process for sucrose monolaurate (sucrose ester) production from lauric acid with high productivity and selectivity. In the first stage, lauric acid was firstly converted into methyl laurate via esterification, followed by the transesterification of methyl laurate into sucrose ester in the second stage. In this research, the first stage of process was primarily focused and thoroughly evaluated.

Disparities in Gender Preference and Fertility: Southeast Asia and Latin America in a Comparative Perspective.

A preference for sons and a sex selection against females are widespread in vast regions of the world, including a great number of Asian and East European countries. However, while a robust son bias has been widely studied in several countries of these regions, much less attention has been given to other regions, such as Latin America. The aim of this paper is to compare gender preferences in twelve selected countries of Southeast Asia and Latin America at the beginning of the 21st century by calculating to what extent parents adapt their fertility behaviors to ensure the birth of a preferred sex.

Midterm results and complications rates in vancouver type B2 and B3 periprosthetic femoral fractures treated with modular fluted tapered stems.

Unlabelled: Evaluate the mid-term success rate of these stems in periprosthetic femur fractures and to analyze the complications observed with the use of these stems.

Methods: Thirty five patients that underwent hip revision surgery secondary to Vancouver type B2 and B3 periprosthetic femur fracture were evaluated. In all cases, modular fluted tapered stems were used.

A systematic review and meta-analysis of the cyclic alternating pattern across the lifespan.

Background: Cyclic alternating pattern (CAP) is the electroencephalogram (EEG) pattern described as a marker of sleep instability and assessed by NREM transient episodes in sleep EEG. It has been associated with brain maturation. The aim of this review was to evaluate the normative data of CAP parameters according to the aging process in healthy subjects through a systematic review and meta-analysis.
