Prolactin Assay Interference by Macroprolactin.

Background: Macroprolactinemia is a common presentation especially in gynecology and fertility clinics. However, with this clinical condition, there is a potential for misdiagnosis and unnecessary investigations/treatments due to lack of awareness of its prevalence and diagnostic approaches amongst trainees and physicians.

Methods: In this paper, we discuss the causes of hyperprolactinemia, its pathobiology, and an approach to macro-prolactinemia including relevant clinical chemistry methods and their limitations through the case of a 45-year-old female with a history of irregular menstrual cycles, who was seen in the endocrine clinic.

User-Centered Design Process of an mHealth App for Health Professionals: Case Study.

Background: User-centered design processes are infrequently employed and not fully explored for building mobile health (mHealth) apps that are particularly targeted to health professionals as end users. The authors have used a user-centered design-based approach to build an mHealth app for health professionals, tasked to deliver medical laboratory-related information on a daily basis.

Objective: Our objective is to generate a simple and functional user-centered design process for mHealth apps for health professionals.

Reducing delivery times of emergency blood products through pneumatic tube systems.

Objectives: Recent advances in damage control resuscitation have advocated a push for early transfusion to maintain circulating volume and minimization of crystalloid use. While measures such as using rapid-matched group specific blood or uncrossmatched blood have been implemented to shorten this wait, delivery times can still be improved. We explored reducing delivery times by use of a pneumatic tube delivery system already built in our hospital.
