Background: The burden of ST-segment elevation myocardial infarction (STEMI) worldwide is increasing as the leading cause of death; there are scant data on system-based initiatives and performance metrics relative to its management in low- and middle-income countries where resources are frequently limited.
Objectives: The Global Heart Attack Treatment Initiative (GHATI) ultimate aim is improving evidence-based STEMI care, adherence to guidelines, and tracking of clinical and institutional indicators in low- and middle-income countries. To achieve that goal, the process of care and outcomes of STEMI patients in those nations will be studied.

When we encounter an unfamiliar word in a sentence, word order can be used to determine the grammatical category to which that word belongs and clarify ambiguity. However, it is unclear whether a similar categorization effect occurs in nonlinguistic contexts. We created three perceptually distinct categories of shape stimuli-rounded (A); squared (B); pointed (C).

The approach recasts the multiple-quantum nutation behavior in terms of reduced excitation and mixing curves through a scaling of the first-order offset frequency by the quadrupolar coupling constant. The two-dimensional correlation of the static first-order anisotropic line shape to the second-order anisotropic magic-angle-spinning (MAS) line shape is utilized to transform the three-dimensional integral over the three Euler angles into a single integral over the dimensionless first-order offset parameter.

In current clinical practice, the management of a cUTI often starts with broad-spectrum antimicrobials until culture and sensitivity (C&S) results are available, but these diagnostic delays further hinder treatment efficacy. Polymerase Chain Reaction (PCR) offers a faster alternative.

Several recent systematic reviews and case series have highlighted common clinical presentations and management strategies. Given the low frequency at which HZ and HZ-D exposures occur, a strong evidence base on which to develop an evidence-based guideline does not exist at this time.
