Severe Symptomatic Hypochloremia Associated with Rare Signet Ring Cell Carcinoma of the Ampulla of Vater: A Case Report.

Hypochloremia is an electrolyte disturbance characterized by low serum concentration of chloride ions, often occurring in acute illnesses and characterized by nonspecific signs and symptoms. It rarely results from decreased intake and is predominantly due to either renal or extra-renal losses. We report a case of severely worsening symptomatic hypochloremia resulting from an extra-renal loss of chloride ion in a 58-year-old female patient presenting for prolonged protracted vomiting.

Rethinking clinical instruction through the zone of proximal development.

Background: The complexity of the learning environment and intricacy of nursing tasks make it difficult for students to learn without the assistance of an expert. Teaching in the zone of proximal development (ZPD) aims at positioning learners in the zone of what they can do and develop with assistance to reach full potential and independence. ZPD is deemed essential to understand how teaching and learning take place; however, its implications for clinical educators are limited and need further exploration.

Using frame analysis to re-analyse the results of inductive thematic analysis: A methodological discussion of investigating meanings and learning contexts in baccalaureate nurse education.

Aims: Recovery of the antecedents and assumptions of Goffman's frame analysis to illustrate learning contexts in baccalaureate nursing programs.

Design: A discussion paper on the secondary analysis of focus group data.

Data Sources: Focus group data collected in a multi-site study conducted in 2017 to understand the challenges of transitioning to practice in Lebanon.

Nonalcoholic Steatohepatitis: Involvement of the Telomerase and Proinflammatory Mediators.

Nonalcoholic steatohepatitis or NASH is an excessive accumulation of fat in hepatocytes accompanied by inflammation and hepatic injury. Proinflammatory molecules such as IL-17, CCL20, S100A8, S100A9, and S100A8/A9 have been shown to be implicated in many types of cancer. Telomerase activity has been found to be associated with chronic inflammation and cancer.

Genetic structure of Octopus vulgaris (Cephalopoda, Octopodidae) in the central Mediterranean Sea inferred from the mitochondrial COIII gene.

The polymorphism of the mitochondrial gene cytochrome oxidase III was studied in the Mediterranean octopus, Octopus vulgaris Cuvier, 1797. A total of 202 specimens from seven sampling sites were analysed with the aim of elucidating patterns of genetic structure in the central Mediterranean Sea and to give an insight into the phylogeny of the Octopus genus. Phylogenetic analyses showed that individuals from the central Mediterranean belong to the O.
