This article was prepared to focus on considerations for performing stress (exercise and pharmacologic) testing in conjunction with MPI. It is meant to 1) provide a basic overview of the principles of exercise stress testing, 2) discuss indications, contraindication, patient preparation and protocols for exercise stress testing, 3) discuss the contraindications administration protocols and side effects for performing vasodilator (adenosine, dipyridamole and regadenoson) stress testing and 4) discuss the contraindications, administration protocols, and side effects for performing dobutamine stress testing.

The aim of this article is to defend the importance of quality measurement in nuclear medicine utilizing the long-standing problem of submaximal exercise stress testing. Numerous evidence-based guidelines and research studies establish the importance of maximal stress testing for myocardial perfusion imaging. The three cutoff thresholds that indicate adequate cardiac stress that must all be met include expenditure of five metabolic equivalents (METs) of energy, production of symptoms (e.g., fatigue or shortness of breath), and attainment of 85 percent of the maximum predicted heart rate. Measurement and evaluation of these three criteria along with several other metrics can help to validate one aspect of laboratory quality related to myocardial perfusion imaging accuracy.

Methods The drug was prepared in an International Organization for Standardization (ISO) 5 environment. Multiple dry baths and needle types were used to investigate the effects of reaction temperature and metal contamination, respectively. Temperature curves were obtained with a calibrated thermocouple. AZD9291 The influence of NETSPOT reagent volume accuracy and its effect on outcome was investigated. Results The AccuBlock dry bath (Labnet International, Inc) required recalibration for the ISO 5 environment; after calibration, the temperature was stable (only ±0.1°C from the set point). When we followed package insert recommendations (dry bath temperature set to 98°C, reaction time of 8 minutes), the reaction teing, Inc.Myocardial perfusion imaging is a routine study that helps to see if the blood flow to the heart muscle is normal or abnormal. There are three parts to myocardium imaging; the resting scan with the radioactive tracer, the stressing of the myocardium, and the stress scan with the radioactive tracer. With the resting scan, a radioactive tracer is injected into the patient to obtain the first set of images of the myocardium at rest. After the rest scan, comes the stressing of the myocardium. There are two different ways to stress the myocardium for the stress test. The first way is to have the patient exercise on a treadmill following a specific exercise protocol, and the second method is to use a pharmacologic stressing agent if the patient cannot exercise. Pharmacologic stress agents produce coronary artery vasodilation and increased myocardial blood flow. During exercise stress, the heart rate should preferably reach 85% of the maximum heart rate and the patient should be symptomatic or fatigued, the technologist injects the patient with the radioactive tracer at peak stress and then obtains a second set of stress images . Of the two different ways to stress the myocardium, the physical stressor is preferred to pharmacologic stress testing in conjunction with myocardial perfusion imaging.

METHODS Cognitive/behavioral profiles were examined in 98 patients (59 ALS-FTD and 39 bvFTD). The initial presentation of ALS-FTD was categorized into either motor or cognitive. Survival was calculated from initial symptom onset. MRI brain atrophy patterns were examined using a validated visual rating scale. RESULTS In the ALS-FTD group, 41 (69%) patients were categorized as having an initial cognitive presentation and 18 (31%) a motor presentation. Patients with motor presentation experienced a significantly shorter median survival of 2.7 years compared to 4.4 years (p less then 0.001) in those with a cognitive presentation. No differences between motor vs cognitive onset ALS-FTD were found on cognitive testing. When compared to bvFTD, ALS-FTD-cognitive presentation was characterized by reduced language function (p less then 0.001), verbal fluency (p = 0.001), and naming (p = 0.007). Both motor and cognitive onset ALS-FTD showed reduced emotion processing (p = 0.01) and exhibited greater motor cortex and dorsal lateral prefrontal cortex atrophy than bvFTD. AZD9291 Increased motor cortex atrophy was associated with 1.5-fold reduction in survival. CONCLUSIONS Initial motor presentation in ALS-FTD leads to faster progression than in those with a cognitive presentation, despite similar overall cognitive deficits. These findings suggest that disease progression in ALS-FTD may be critically linked to physiologic and motor changes. © 2020 American Academy of Neurology.OBJECTIVE To investigate whether in utero exposure to the Great Chinese Famine in 1959 to 1961 was associated with risk of intracerebral hemorrhage (ICH) in adulthood. METHODS In this cohort analysis, we included 97,399 participants of the Kailuan Study who were free of cardiovascular disease and cancer at baseline (2006). Cases of incident ICH were confirmed by medical record review. We used the Cox proportional hazards model to calculate the hazard ratio (HR) and 95% confidence interval (CI) for ICH according to in utero famine exposure status. RESULTS Among 97,399 participants in the current analyses, 6.3% (n = 6,160) had been prenatally exposed to the Great Chinese Famine. During a median 9.0 years of follow-up (2006-2015), we identified 724 cases of incident ICH. After adjustment for potential confounders, the HR of ICH was 1.99 (95% CI 1.39-2.85) for in utero famine-exposed individuals vs individuals who were not exposed to the famine. When exposure to famine and severity of famine were examined jointly, the adjusted HR was 2.
