[A front-of-pack labelling system for food and beverages for Mexico: a strategy of healthy decision-making.].

The Mexican Ministry of Health requested the National Institute of Public Health to constitute a group of independent, free of conflict-of-interest academic experts on front-of-pack labelling (FOP). This group was instructed to created a positioning paper to contribute to the development of a FOP system for industrialized products that offers useful information for purchase decision making. This position paper uses the best available scientific evidence, and recommendations from experts of international organizations.

Myocardial single-photon emission computed tomographic imaging with technetium 99m tetrofosmin: stress-rest imaging with same-day and separate-day rest imaging.

Background: Technetium 99m tetrofosmin is a new ethylene diphosphine ligand for myocardial perfusion imaging and has unique properties. We have compared stress-rest single-photon emission computed tomographic (SPECT) imaging with 99mTc tetrofosmin with same-day and separate-day rest imaging to detect myocardial perfusion defects.

Methods And Results: Myocardial SPECT imaging was performed in 22 patients with coronary artery disease who had undergone planar thallium 201 imaging and coronary angiography.

Myocyte cell damage after administration of doxorubicin or mitoxantrone in breast cancer patients assessed by indium 111 antimyosin monoclonal antibody studies.

Purpose: To compare myocyte cell damage induced by doxorubicin or mitoxantrone, we performed left ventricular ejection fraction (LVEF) measurements and indium 111 antimyosin antibody studies in a group of patients with advanced breast cancer who had been treated with these anthracycline derivatives.

Patients And Methods: We studied 35 patients eligible to receive chemotherapy including the anthracyclines: doxorubicin or mitoxantrone (cumulative dose of doxorubicin, 500 mg/m2; or mitoxantrone, 120 mg/m2). LVEF was measured before and after 10 cycles of chemotherapy.

Preexisting human anti-murine antibodies and the effect of immune complexes on the outcome of immunoscintigraphy.

Radiolabeled monoclonal antibodies (MoAb) are useful in radionuclide imaging. Human anti-murine antibodies (HAMA), however, could produce immunologic effects or alter the outcome of immunoscintigraphy. Three patients are reported who had been exposed previously to radiolabeled MoAbs and in whom subsequent immunoscintigraphy was performed.

[Biventricular functional adaptation during a prolonged race. An analysis of global and regional ventricular function].

To determine the effects of a six-hour competitive race on left and right ventricular performance, 99mTc gated blood pool scans were performed to 6 long distance runners before the race (rest), each hour during the race and one hour after concluding the exercise (recovery). Heart rate increased during the race, peaking at 4th hour of competition (55 +/- 3 to 110 +/- 9 lpm; p = 0.001).
