Current Status of Newborn Bloodspot Screening Worldwide 2024: A Comprehensive Review of Recent Activities (2020-2023).

Newborn bloodspot screening (NBS) began in the early 1960s based on the work of Dr. Robert "Bob" Guthrie in Buffalo, NY, USA. His development of a screening test for phenylketonuria on blood absorbed onto a special filter paper and transported to a remote testing laboratory began it all.

Newborn screening in Latin America: A brief overview of the state of the art.

Latin America is a region consisting of 20 countries that present a wide diversity in terms of a geographic area as well as demographics, ethnicity, economy, social, and healthcare systems. This diversity also applies to the newborn screening (NBS) activities, as demonstrated by the start dates and modalities of implementation as organized programs, the panel of diseases screened for, the available technologies for testing, the coverage, the legislation in force, and the degree of development and success reached. Based on these characteristics, Latin American countries can currently be classified into five groups ranging from fully established national programs to no program at all.

Current status of newborn screening worldwide: 2015.

Newborn screening describes various tests that can occur during the first few hours or days of a newborn's life and have the potential for preventing severe health problems, including death. Newborn screening has evolved from a simple blood or urine screening test to a more comprehensive and complex screening system capable of detecting over 50 different conditions. While a number of papers have described various newborn screening activities around the world, including a series of papers in 2007, a comprehensive review of ongoing activities since that time has not been published.

An easy and sensitive method for determination of globotriaosylceramide (Gb3) from urinary sediment: utility for Fabry disease diagnosis and treatment monitoring.

Background: Fabry disease is an X-linked disorder that results from the deficiency of the lysosomal enzyme alpha-galactosidase A. The defect leads to the accumulation of globotriaosylceramide (Gb3). The detection of Gb3 accumulated in different tissues may help in the diagnosis and enzyme replacement therapy monitoring.
