Abstract

Background: With the increased interest in inter-recti distance measurement using ultrasound imaging in physiotherapy, there is a question of measurement reliability, and the importance of the examiner's experience. Purpose: The study aimed to investigate the reliability of inter-recti distance measurement in a DICOM viewer software by an experienced radiologist. For the measurement, the radiologist used linea alba images captured by two physiotherapists who were novice examiners. Methods: Ultrasound images were acquired by two novice examiners on repeated occasions 7 days apart (sessions A and B) in 28 nulliparous women at supraumbilical, umbilical, and infraumbilical locations along linea alba. Results: Excellent intra-examiner reliability of inter-recti distance measurements was shown at the supraumbilical and umbilical levels (ICC2,k = 0.941–0.983) with minimal detectable change (MDC95) ranging from 1.31 mm to 2.29 mm. Infraumbilical measurements had good to excellent reliability (ICC2,k = 0.894–0.972) with MDC95 ranging from 0.33 mm to 0.72 mm. Session A inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at each location (ICC2,k = 0.913–0.954) with MDC95 ranging from 0.47 mm to 2.96 mm. Session B inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at the supraumbilical and umbilical (ICC2,k = 0.94–0.98), MDC95 ranging from 1.38 mm to 2.58 mm and good (ICC2,k ≥ 0.81) with MDC95 ranging from 0.72 mm to 0.80 mm at the infraumbilical locations. Conclusion: Novice examiners were able to capture good-quality ultrasound images of the linea alba that allowed for good to excellent intra- and inter-examiner reliability. [ABSTRACT FROM AUTHOR]

Abstract

Embolization is the preferred method for treating intracranial aneurysms due to its less invasive nature. However, recent findings suggest that even uncomplicated embolization may cause structural damage to the brain through ischemic or inflammatory mechanisms. This study aimed to find possible biomarkers of brain injury and inflammation in patients suffering from intracranial aneurysms who underwent endovascular treatment by measuring serological markers indicating brain damage. The study involved 26 patients who underwent uncomplicated intravascular stenting for unruptured intracranial aneurysms between January 2020 and December 2021. Blood samples were collected before the procedure, at 6–12 h, and at 24 h after the procedure. The following protein biomarkers levels were tested with ELISA: S100B, hNSE, TNF, hsCRP, FABP7, NFL, and GP39. Statistical analysis of the results revealed significant increases in serum levels for the four biomarkers: FABP7—before 0.25 (ng/mL) vs. 6–12 h 0.26 (p = 0.012) and vs. 24 h 0.27 (p < 0.001); GP39—before 0.03 (pg/mL) vs. 6–12 h 0.64 (p = 0.011) and vs. 24 h 0.57 (p = 0.001); hsCRP—before 1.65 (μg/mL) vs. 24 h 4.17 (p = 0.037); NFL—before 0.01 (pg/mL) vs. 6–12 h 3.99 (p = 0.004) and vs. 24 h 1.86 (p = 0.033). These biomarkers are recognized as potential indicators of neurovascular damage and should be monitored in clinical settings. Consequently, serum levels of NFL, GP39, hsCRP, and FABP7 measured before and 24 h after endovascular procedures can serve as important markers for assessing brain damage and indicate avenues for further research on biomarkers of neurovascular injury.

34. Back pressure effect on three-way catalyst light-off.

Author

Baron, Jan H, Cheng, Wai K, and Kamimoto, Takeyuki

Abstract

The effect of back pressure on the light-off of a modern spark ignition engine three-way catalyst has been assessed by measuring the hydrocarbon conversion efficiency in a hot flow bench and in the cold-idle period in an engine. In the flow bench experiment, a small amount of propane/air mixture is used as a surrogate for the hydrocarbon mixture. The conversion efficiency is found to be only a function of temperature. The efficiency is independent of pressure, space velocity, and the equivalence ratio of the hydrocarbon mixture for λ ≥ 1. In the engine test, while the engine-out exhaust gas temperature is higher at a higher back pressure, there is little difference between the gas temperatures at the catalyst entrance for different back pressures at retarded spark timing. This observation is attributed to the larger amount of exhaust hydrocarbon conversion oxidation between the engine exit and the catalyst entrance with the lower back pressure. The heat release from this oxidation compensates for the lower engine-out exhaust temperature at the lower back pressure. The catalyst temperature increases modestly and light-off time shortens correspondingly at the higher back pressure. This observation is attributed solely to the increase in mass flow rate (and thus exhaust sensible enthalpy flow rate) of the engine needed to overcome the additional pumping loss due to the throttling of the exhaust. These results have been confirmed with a simple one-dimensional catalyst model. [ABSTRACT FROM AUTHOR]

Abstract

Sylwester Rodkiewicz’s Columba gemens et dolens... is the occasional sermon from the second half of the seventeenth century, preached on the day when the indulgence was applied, the celebration day of the Suff ering Virgin Mary. Due to the question if a printed text can be treated as a recorded form of the preaching appearance, in the article, the expected function of the printed work was defi ned as well as the composition of the piece was analysed. A part of the article was devoted to the description of rhetorical operations used by the preacher, the role of which was to lead to the main achievement – a persuasive aim (the encouragement to the passion piety, following the model of cosuff ering Virgin Mary). Th ese operations included the construction of vivid statements and the introduction of preachable conceits. Th e conceit based on a metaphor presented in the title, played also an important role as an element infl uencing the shape of extensive passages of the sermon. Th e analysis of the work confi rms the thesis concerning the dependence between the sermon-conceit and the emblematic form. Th e audience is infl uenced both by the conceit and the emblem, which is based on the same mechanism – in the course of the disquisition, the presence of the connection between initially contradictory elements is shown.

Abstract

Background: Progressive stenosis of the supraclinoid segments of the internal carotid arteries, followed by formation of characteristic collateral brain circulation is typical for moyamoya disease. This illness, with unknown pathogenesis, is often diagnosed in Asiatic population. In Poland it can be a rare cause of ischemic infarcts in children. Case report: Two cases of cerebral ischemic infarct due to moyamoya disease in girls aged 7 and 12 are presented. The final diagnosis was established after MR exams and digital subtraction angiography (DSA) of the cerebral arteries. Conclusions: In spite of rare incidence, the moyamoya disease should be considered as the potential cause of cerebral ischemic infarctions in children. Despite the main role of the DSA in establishment of the final diagnosis, noninvasive neuroradiological examinations become more and more important in diagnostic schedule of moyamoya disease. MR and MR angiography visualize characteristic radiological symptoms, enabling preliminary diagnosis and are the method of choice in control examinations.

Abstract

Aims South Asian (SA) patients are known to have an increased incidence of acute cardiovascular events compared with Caucasians. The aim of this observational study was to compare the prevalence of coronary stenoses, the amount and composition of coronary atherosclerosis in a cohort of Caucasian and SA patients with stable chest pain, in non-acute settings. Methods and results The study protocol conformed to the ethical guidelines of the 1975 Declaration of Helsinki. In 963 consecutive Caucasian and SA patients undergoing coronary computed tomography angiography, atherosclerotic plaques were quantified using a semi-automated algorithm. The vessel per cent diameter and area stenosis were measured. Plaque composition was examined from the measurement of calcified, non-calcified, and total plaque burden. There were 420 Caucasian (238 males) and 543 SA (297 males) patients. Caucasian patients were older than SA patients (54.39 ± 11.65 vs. 49.83 ± 11.03 years) and had lower prevalence of diabetes (13.13 vs. 32.41%) and hyperlipidaemia (56.90 vs. 68.51%) (all P-values <0.001). After adjusting for differences in cardiovascular risk factors, there were no differences in per cent diameter and area stenosis, and no difference in the proportions of patients with one-, two-, or three-vessel disease. There was no difference in total plaque burden; however, the per cent non-calcified plaque composition was lower in Caucasians compared with SA (80.95 vs. 90.42%; P-value <0.001). Conclusion This study conducted in non-acute settings showed an ethnic difference in composition of coronary atherosclerotic plaque with lower non-calcified composition in Caucasian patients compared with SA patients, which was independent of age, diabetes, hyperlipidaemia, and the other available cardiovascular risk factors.
