Recently, the applicability of somatostatin receptor-targeted (SSTR-t) radiotracers for post-ischemic myocardial inflammation imaging has been shown using PET. Currently, there are no studies which demonstrate ability of SPECT and technetium-99m SSTR-t radiotracers to detect inflammation, which appears in response to acute myocardial infarction (AMI). A case of 51-year-old male with acute anterior myocardial infarction (AMI) with ST elevation has been presented. This patient on 7th day after AMI onset underwent SPECT/CT (by cardiac cadmium-zinc-telluride gamma-camera) with 99mTc-Tectrotide, cardiac MRI with gadolinium and, on 9th day after AMI, myocardial perfusion scintigraphy (MPS) at rest. Clear myocardial uptake of 99mTc-Tectrotide, predominantly in apical and intermediate anterior wall of left ventricle was detected. The uptake matched with areas of hypoperfusion (by SPECT) and myocardial injury (by MRI). This case demonstrated the applicability of technetium-99m-labeled SSTR-t radiotracers for post-infarction inflammation imaging. 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. GSK2656157 cell line 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. Compared with 60-s resting pressure, measurements had perfect correlation (κ = 1.0) over 30s, and substantial correlation (κ = 0.85) over 10s. After SS1, SS2, and SS3, 43%, 49%, and 46% had anal hypocontractility, respectively. Correlation was substantial between SS1 and SS2 (κ = 0.799) and almost perfect between SS2 and SS3 (κ = 0.9). Compared to resting pressure of 5s before SS1, pressure recordings at 25-30 and 15-20s after SS1 were significantly correlated.

A 30-s resting anal pressure, analysis of 2 short-squeezes with a 20-s between-maneuver recovery optimizes study duration without compromising diagnostic accuracy. These findings indicate the IAPWG protocol has redundancy.

The gut microbiota are reported to be altered in critical illness. The pattern and impact of dysbiosis on prognosis has not been thoroughly investigated in the ICU setting.

We aimed to evaluate changes in the gut microbiota of ICU patients via 16S rRNA gene deep sequencing, assess the association of the changes with antibiotics use or disease severity, and explore the association of gut microbiota changes with ICU patient prognosis.

Seventy-one mechanically ventilated patients were included. Fecal samples were collected serially on days 1-2, 3-4, 5-7, 8-14, and thereafter when suitable. Microorganisms of the fecal samples were profiled by 16S rRNA gene deep sequencing.

Proportions of the five major phyla in the feces were diverse in each patient at admission. Those of Bacteroidetes and Firmicutes especially converged and stabilized within the first week from admission with a reduction in α-diversity (p < 0.001). Significant differences occurred in the proportional change of Actinobacteria between the carbapenem and non-carbapenem groups (p = 0.030) and that of Actinobacteria according to initial SOFA score and changes in the SOFA score (p < 0.001). An imbalance in the ratio of Bacteroidetes to Firmicutes within seven days from admission was associated with higher mortality when the ratio was > 8 or < 1/8 (odds ratio 5.54, 95% CI 1.39-22.18, p = 0.015).

Broad-spectrum antibiotics and disease severity may be associated with gut dysbiosis in the ICU. A progression of dysbiosis occurring in the gut of ICU patients might be associated with mortality.

Factors affecting pregnancy-related knowledge in women with inflammatory bowel disease (IBD) remain unknown. We aimed to determine these factors and to assess the impact of a dedicated pregnancy clinic on improving knowledge in women with IBD.

Adult women with IBD attending the pregnancy IBD clinic at the University of Alberta from 2014 to 2018 were enrolled. Each patient completed the Crohn's and Colitis Pregnancy Knowledge (CCPKnow) questionnaire at baseline and after individualized education delivered at each clinic visit. Knowledge levels were defined as very good if CCPKnow scores ≥ 14. Mean CCPKnow scores were reported with standard deviations (SD) and compared using the paired T test.

The mean CCPKnow score in 117 patients at baseline was 9.65 (SD 4.18). Compared to those with disease duration < 5years, those with disease duration > 5years had higher rates of very good baseline knowledge (3.0% vs. 26.4%, p = 0.036). Similarly, those on preconception IBD-related therapy were more likely to have very good knowledge compared to those on no therapy (22.5% vs. 0%, p = 0.024). Fifty-one patients completed a post-clinic CCPKnow survey with a mean CCPKnow of 10.72 (SD 4.32). Participation in a pregnancy clinic improved reproductive knowledge in those with ulcerative colitis (p = 0.001), disease duration > 5years (p = 0.017), those with at least a university education (p = 0.014) and those on IBD-related therapies (p = 0.026).

Increased disease duration and preconception IBD-related therapy may be associated with increased pregnancy-related knowledge. A dedicated pregnancy clinic can improve reproductive knowledge in women with IBD.
