Validation of the TWIST score for testicular torsion in adults.

Purpose: The TWIST (Testicular Work-up for Ischemia and Suspected Torsion) score was developed to allow for expedited diagnosis of testicular torsion (TT) in children based on clinical variables: edema (2 points), hard mass (2), absent cremasteric reflex (1), high-riding testis (1) and nausea/vomiting (1). We sought to validate the TWIST Score applied by non-expert physicians for the diagnosis of testicular torsion in an adult population.

Methods: We prospectively analyzed all consecutive males presenting to a tertiary hospital with acute scrotum.

Transition to universal primary health care coverage in Brazil: Analysis of uptake and expansion patterns of Brazil's Family Health Strategy (1998-2012).

Family Health Strategy, the primary health care program in Brazil, has been scaled up throughout the country, but its expansion has been heterogeneous across municipalities. We investigate if there are unique municipal characteristics that can explain the timing of uptake and the pattern of expansion of the Family Health Strategy from years 1998 to 2012. We categorized municipalities in six groups based on the relative speed of the Family Health Strategy uptake and the pattern of Family Health Strategy coverage expansion.

Brazil's Family Health Strategy: factors associated with programme uptake and coverage expansion over 15 years (1998-2012).

Universal Health Coverage (UHC) is one of the United Nations Sustainable Development Goals (SDGs). Achieving UHC will require strong health systems to promote and deliver equitable and integrated healthcare services through primary healthcare (PHC). In Brazil, the Family Health Strategy (FHS) delivers PHC through the public health system.
