Currently assumed, that SSTR-t radiotracers reflect an increased number of activated macrophages infiltrating infarcted myocardium, which is not possible using any other imaging technique. Thus, potentially, SSTR scintigraphy may be useful for diagnosis and monitoring of myocardial post-infarction inflammation as well as for anti-inflammatory image-guide therapy assessment.Cardiac PET-derived measurements of myocardial blood flow (MBF) and myocardial flow reserve (MFR) are proven robust indexes of the severity of coronary artery disease (CAD). They facilitate the diagnosis of diffuse epicardial and microvascular disease and are also of prognostic significance. However, low availability and high cost have limited their wide clinical implementation. Over the last 15 years, cadmium zinc telluride (CZT)-based detectors have been implemented into SPECT imaging devices. Myocardial perfusion scintigraphy can be performed faster and with less radiation exposure as compared with standard gamma cameras. Rapid dynamic SPECT studies with higher count rates can be performed. This technological breakthrough has renewed the interest in SPECT MBF assessment in patients with CAD. Currently, two cardiac-centered CZT gamma cameras are available commercially-Discovery NM530c and D-SPECT. They differ in parameters such as collimator design, number of detectors, sensitivity, spatial resolution and image reconstruction. A number of publications have focused on the feasibility of dynamic CZT SPECT and on the correlation with cardiac PET and invasive coronary angiography measurements of fractional flow reserve. Current study reviews the present status of MBF and MFR assessment with CZT SPECT. It also aims to provide an overview of specific issues related to acquisition, processing and interpretation of quantitative studies in patients with CAD.

Patients with chronic obstructive pulmonary disease (COPD) often report deteriorated functional status and poor health-related quality of life, both core aspects of their overall health status. The study objective was to assess tiotropium/olodaterol Respimat

effects on health and functional status of COPD patients requiring long-acting dual bronchodilation treatment in the real world.

ELLACTO was an open-label, observational, prospective study conducted in Greece, measuring changes on health and functional status of COPD patients treated with a fixed dose of tiotropium/olodaterol Respimat

for approximately 6weeks. The primary endpoint was "therapeutic success" defined as a ≥ 0.4-point decrease in the Clinical COPD Questionnaire (CCQ) score at week 6. Secondary endpoints included absolute changes in the CCQ and the functional subscale CCQ-4 at week 6, patient general condition measured by Physician's Global Evaluation (PGE) score at baseline and week 6, patient satisfaction and preference with RespimatOPD patients. Most patients also expressed a preference for the Respimat

device and willingness to continue treatment with it.

Differences in selective attention are commonly observed in autism and we investigated whether exogenous (automatic) shift costs between modalities are increased. Autistic adults and neurotypical controls made speeded discrimination responses to simple visual, tactile and auditory targets. Shift costs were observed for each target modality in participant response times and were largest for auditory targets, reflective of fast responses on auditory repeat trials. Critically, shift costs were similar between the groups. However, integrating speed and accuracy data using drift-diffusion modelling revealed that shift costs in drift rates (reflecting the quality of information extracted from the stimulus) were reduced for autistic participants compared with neurotypicals. It may be that, unlike neurotypicals, there is little difference between attention within and between sensory modalities for autistic people. This finding also highlights the benefit of combining reaction time and accuracy data using decision models to better characterise selective attention in autism.The present study explored how task instructions mediate the impact of action on perception. Participants saw a target object while performing finger movements. Then either the size of the target or the size of the adopted finger postures was judged. The target judgment was attracted by the adopted finger posture indicating sensory integration of body-related and visual signals. The magnitude of integration, however, depended on how the task was initially described. It was substantially larger when the experimental instructions indicated that finger movements and the target object relate to the same event than when they suggested that they are unrelated. This outcome highlights the role of causal inference processes in the emergence of action specific influences in perception.

Anorectal manometry (ARM) is essential for identifying sphincteric dysfunction. The International Anorectal Physiology Working Group (IAPWG) protocol and London Classification provide a standardized format for performing and interpreting ARM. However, there is scant evidence to support timing and number of constituent maneuvers.

To assess the impact of protocol modification on diagnostic accuracy in patients with fecal incontinence.

Retrospective analysis of high-resolution ARM recordings from consecutive patients based on the current IAPWG protocol and modifications thereof (1) baseline rest period (60 vs. 30 vs. 10s); (2) number of abnormal short squeezes (SS) out of 3 (SS1/SS2/SS3) based on maximal incremental squeeze pressures over 5s; (3) resting anal pressures (reflecting recovery) at 25-30 versus 15-20s after SS1.

One hundred patients (86 F, median age 55 [IQR 39-65]; median St. Mark's incontinence score 14 [10-17]) were studied. 26% and 8% had anal hypotonia and hypertonia, respectively. GSK1070916 Compared with 60-s resting pressure, measurements had perfect correlation (κ = 1.
