Ultrasound of Bile Ducts-An Update on Measurements, Reference Values, and Their Influencing Factors.

To provide an overview of the technique and normal values of ultrasound studies of the bile system based on the published literature. A literature search for ultrasound studies with measurements of the bile ducts in healthy subjects was performed. Relevant data published between 1975 and end of 2024 were extracted, discussed, and complemented with the own experiences of the authors.

Gastrointestinal Ultrasound: Measurements and Normal Findings - What Do You Need to Know?

Background: A standardized examination procedure and correct bowel wall assessment are the prerequisites for correct findings and for distinguishing normal findings from pathological diagnoses. PubMed was searched for the time period from January 01, 1990, to March 29, 2024, using a Boolean search.

Summary: The present work provides knowledge and details of the examination of the gastrointestinal tract in transcutaneous ultrasound with examination procedure, transducer selection, transducer guidance, knowledge of the identification of anatomical structures, and sonographic assessment.

Revealing schoolchildren's key situations in the use of digital media inside and outside school: A media diary study.

Introduction: Digital media have become integral to schoolchildren's lives, both within educational and non-educational settings. Educators emphasize the importance of bridging the gap between school learning and children's out-of-school activities. To identify potential variations and commonalities, we investigated key situations with digital media among lower secondary schoolchildren in Germany, aiming to determine which themes are especially relevant in different settings.

Ultrasound of the spleen - an update on measurements, reference values, and influencing factors. A systematic review.

Reliable and reproducible measurement methods have been established, and reference values are used in almost all scientific disciplines. The knowledge of reference values is crucial to distinguish physiological from pathological processes and, therefore, subsequently, for the clinical management of patients. The image storage and documentation of measurements and normal findings should be part of quality assurance in imaging.

Pancreatic ultrasound: An update of measurements, reference values, and variations of the pancreas.

Reliable and reproducible measurement methods have been established, and reference values are used in almost all scientific disciplines. Knowledge of reference values is crucial to distinguish physiological from pathological processes and, therefore, subsequently, for the clinical management of patients. Image storage and documentation of measurements and normal findings should be part of quality assurance in imaging.

Why workshops work: Examining the efficacy of training trainers to train goats.

Experimental procedures involving farm animals are often associated with stress due to restraining. Stress can be reduced through use of positive reinforcement training, which then serves as refinement according to the 3Rs principles. Trainer skills, however, may influence the feasibility and success of animal training.

Understanding psychology students' perspective on video psychotherapy and their intention to offer it after graduation: a mixed-methods study.

Introduction: Video psychotherapy (VPT) demonstrated strong clinical efficacy in the past, with patients and psychotherapists expressing satisfaction with its outcomes. Despite this, VPT only gained full recognition from the German healthcare system during the COVID-19 pandemic. As society increasingly relies on new media, it seems likely that VPT will become even more relevant.

"Do not look at me like that": Is the facial expression score reliable and accurate to evaluate pain in large domestic animals? A systematic review.

Introduction: Facial expression scoring has proven to be useful for pain evaluation in humans. In the last decade, equivalent scales have been developed for various animal species, including large domestic animals. The research question of this systematic review was as follows: is facial expression scoring (intervention) a valid method to evaluate pain (the outcome) in large domestic animals (population)?

Method: We searched two databases for relevant articles using the search string: "grimace scale" OR "facial expression" AND animal OR "farm animal" NOT "mouse" NOT "rat" NOT "laboratory animal.

VascuFit: vascular effects of non-linear periodized exercise training in sedentary adults with elevated cardiovascular risk - protocol for a randomized controlled trial.

Background: Early vascular aging (EVA) is increasingly prevalent in the general population. Exercise is important for primary cardiovascular prevention, but often insufficient due to ineffective training methods and a lack of biomarkers suitable to monitor its vascular effects. VascuFit will assess the effectiveness of non-linear periodized aerobic exercise (NLPE) in a non-athletic sedentary population to improve both established and promising biomarkers of EVA.

Bored at home?-A systematic review on the effect of environmental enrichment on the welfare of laboratory rats and mice.

Boredom is an emotional state that occurs when an individual has nothing to do, is not interested in the surrounding, and feels dreary and in a monotony. While this condition is usually defined for humans, it may very well describe the lives of many laboratory animals housed in small, barren cages. To make the cages less monotonous, environmental enrichment is often proposed.

Alone Together: Computer-Mediated Communication in Leisure Time During and After the COVID-19 Pandemic.

In spring 2020, the COVID-19 outbreak was declared a global pandemic and several lockdowns were followed in Germany. To weaken the spread of the virus, SARS-CoV-2, people were required to reduce their face-to-face contact with others. Computer-mediated communication (CMC) offers opportunities to stay in touch with important people and still meets social needs.

Development and performance evaluation of a streamlined method for nucleic acid purification, denaturation, and multiplex detection of Bluetongue virus and Epizootic hemorrhagic disease virus.

Bluetongue virus (BTV) and Epizootic hemorrhagic disease virus (EHDV) possess similar structural and molecular features, are transmitted by biting midges (genus Culicoides), and cause similar diseases in some susceptible ruminants. Generally, BTV causes subclinical disease in cattle, characterized by a prolonged viremia. EHDV-associated disease in cattle is less prominent; however, it has emerged as a major economic threat to the white-tailed deer (Odocoileus virginianus) industry in many areas of the United States.

The other side of the needle: a patient's perspective.

Cytopathology laboratories monitor the analytical processes that have an impact on patient care through sound, quality assurance programs. What often frustrates pathologists is their relative inability to influence pre-analytical variables, those processes that are health-care-provider driven. The performance of fine-needle aspirates (FNAs) is a unique opportunity for the pathologist to become directly involved in the pre-analytical phase of patient care.

Concurrent cesarean section and hand port-assisted laparoscopic cholecystectomy: a safe approach.

Symptomatic gallstones are common in pregnancy. Historically, surgical management of this problem by laparoscopic cholecystectomy was deferred until after delivery and recovery. However, improved optics and tools for accessing the peritoneum make laparoscopic cholecystectomy concurrently with cesarean section an attractive option with minimal additional morbidity.
