The population prevalence of undetected abdominal aortic aneurysm in New Zealand Māori.

Background: The prevalence of abdominal aortic aneurysm (AAA) in Polynesian populations such as the New Zealand Māori has not been characterized. We measured this in a large population-based sample.

Methods: A cross-sectional population-based prevalence study was conducted as part of an AAA screening pilot; 2467 Māori men aged 54 to 74 years and 1526 women aged 65 to 74 years registered with a primary care practice in Auckland (New Zealand) were invited to be screened by abdominal ultrasound between June 2016 and March 2018.

Measuring unexplained variation in acute hospital use by patients enrolled with northern New Zealand general practices.

Introduction: There is increasing concern worldwide at the steady growth in acute inpatient admissions and emergency department (ED) attendances.

Aim: To develop measures of variation in acute hospital use between populations enrolled at different general practices that are independent of the sociodemographic characteristics of those populations.

Methods: Two consecutive years of hospital discharge and ED attendance data were combined with primary health organisation (PHO) registers from 385 practices of over 1.

The effect of Māori ethnicity misclassification on cervical screening coverage.

Aim: There is a large difference in the cervical screening coverage rate between Māori and European women in New Zealand. This paper examines the extent to which this difference is due to misclassification of ethnicity.

Methods: Data from Waitemata District Health Board's two Primary Health Organisations (PHOs) was used to identify the population of Waitemata domiciled women aged 25-69 years eligible for cervical screening.

[Endoscopic ultrasound-fine needle aspiration (EUS-FNA) for pancreatic lesions: effectiveness in clinical practice].

Unlabelled: Endoscopic ultrasound-fine needle aspiration (EUS-FNA) was shown to be a highly reliable and a very effective diagnostic technique, both based on data from clinical trials and from large clinical practice studies. EUS-FNA results are reported to be in good-to-very good agreement with the final diagnosis, and the agreement significantly exceeded the chance agreement. The overall sensitivity and specificity of EUS and of EUS-FNA are very good.

[The nurse's role in endoscopic ultrasonography].

The role of trained nurses in endoscopic ultrasonography (EUS) examination is very relevant for the quality and results of EUS. Nurses have many tasks in EUS. To prepare the endoscopic room with the right instrument and necessary devices for examination of the upper or lower GI tract is very important.
