Blind positioning of a high-resolution manometry (HRM) probe across the esophagogastric junction (EGJ) is not always possible. We report our experience using guidewire-assisted water-perfused HRM probe insertion when the EGJ could not be traversed.

Retrospective study analyzing the failure rate of EGJ insertion during HRM, and reporting a series of guidewire-assisted procedures.

Among 2727 HRM procedures, the failure rate for traversing the EGJ was 2.7% (73 patients). The technique of guidewire-assisted placement of the HRM probe was used in 25 patients; it was well-tolerated and successful in all patients. No motility disorder was found in 6 patients. In four patients with previously diagnosed achalasia, achalasia subtype changed to type III in one patient. While a suspected motility disorder at barium esophagram and/or initial imperfect HRM tracing was confirmed in 10 patients, a new motility disorder was diagnosed in five patients using guidewire-assisted placement of the HRM probe.

In cases of inability to traverse the EGJ, insertion of a water-perfused HRM probe using an endoscopically-placed nasogastric guidewire allows successful EGJ and esophageal peristalsis assessment. Although motility disorders are often suspected using alternative diagnostic modalities, guidewire-assisted placement of HRM may be helpful for revealing them in patients where alternative diagnostic modalities are either unavailable or inconclusive.

Nonetheless, a number of challenges exist when using MEG to image infant populations. There is a persistent belief that collecting MEG data with infants presents a number of limitations and challenges that are difficult to overcome. Due to this notion, many researchers either avoid conducting infant MEG research or believe that, in order to collect high-quality data, they must impose limiting restrictions on the infant or the experimental paradigm. In this article, we discuss the various challenges unique to imaging awake infants and young children with MEG, and share general best-practice guidelines and recommendations for data collection, acquisition, preprocessing, and analysis. The current article is focused on methodology that allows investigators to test the sensory, perceptual, and cognitive capacities of awake and moving infants. We believe that such methodology opens the pathway for using MEG to provide mechanistic explanations for the complex behavior observed in awake, sentient, and dynamically interacting infants, thus addressing core topics in developmental cognitive neuroscience.A ferromagnetic metal nanolayer with a large perpendicular magnetic anisotropy, small saturation magnetization, and small magnetic damping constant is a crucial requirement for high-speed spintronic devices. Fabrication of these devices on Si/SiO2 amorphous substrates with polycrystalline structure is also strongly desired for the mass production industry. This study involves the investigation of sub-terahertz (THz) magnetization precessional motion in a newly developed material system consisting of Cu2 Sb-type MnAlGe and (Mn-Cr)AlGe films by means of an all-optical pump-probe method. These materials exhibit large perpendicular magnetic anisotropy in regions of a few nanometers in size. The pseudo-2D crystal structures are clearly observed in the high-resolution transmission electron microscopy (TEM) images for the film samples grown on thermally oxidized silicon substrates. The TEM images also show a partial substitution of Cr atoms for the Mn sites in MnAlGe. A magnetization precession frequency of 0.164 THz with a relatively small effective magnetic damping constant of 0.012 is obtained for (Mn-Cr)AlGe. Theoretical calculation infers that the modification of the total density of states by Cr substitution decreases the intrinsic magnetic damping constant of (Mn-Cr)AlGe.The neonatal heart can efficiently regenerate within a short period after birth, whereas the adult mammalian heart has extremely limited capacity to regenerate. The molecular mechanisms underlying neonatal heart regeneration remain elusive. Here, we revealed that as a coreceptor of Wnt signalling, low-density lipoprotein receptor-related protein 5 (LRP5) is required for neonatal heart regeneration by regulating cardiomyocyte proliferation. The expression of LRP5 in the mouse heart gradually decreased after birth, consistent with the time window during which cardiomyocytes withdrew from the cell cycle. LRP5 downregulation reduced the proliferation of neonatal cardiomyocytes, while LRP5 overexpression promoted cardiomyocyte proliferation. The cardiac-specific deletion of Lrp5 disrupted myocardial regeneration after injury, exhibiting extensive fibrotic scars and cardiac dysfunction. Mechanistically, the decreased heart regeneration ability induced by LRP5 deficiency was mainly due to reduced cardiomyocyte proliferation. Further study identified AKT/P21 signalling as the key pathway accounting for the regulation of cardiomyocyte proliferation mediated by LRP5. LRP5 downregulation accelerated the degradation of AKT, leading to increased expression of the cyclin-dependent kinase inhibitor P21. Our study revealed that LRP5 is necessary for cardiomyocyte proliferation and neonatal heart regeneration, providing a potential strategy to repair myocardial injury.In this prospective follow-up study, we aimed to examine whether changes in self-reported sleep quality, sleep duration, and sleep medication use are temporally associated with changes in quality of life and work ability in municipal employees when several confounding factors are considered. The study was conducted in Finland among 637 municipal employees (88% women, mean [SD] age 48 [10] years) in 2014 and 2015. Information about the participants was collected by self-administered questionnaire and from medical history. Predicting variables were changes in self-reported sleep quality, sleep duration, and sleep medication use. Outcome variables were changes in the EUROHIS-QOL eight-item index and the Work Ability Score. Improved or unchanged sleep quality compared to worse sleep quality were associated with a preferable change in quality of life (both p  less then  0.001). No change in sleep duration compared to a decrease and no change in sleep medication use compared to increased use were also associated with favourable changes in quality of life. Increased use of sleep medication was associated with a decline in work ability, and the change in Work Ability Score also differed significantly between improved and worsened sleep quality. In this study, changes in sleep were widely associated with changes in quality of life and work ability of municipal employees. Programmes aiming for better sleep health would probably be beneficial both from a health-oriented and an economical point of view. Special attention should be paid to employees with a need for sleep medication.
Recovery of well-being after hospitalisation for acute heart failure (AHF) is a measure of the success of interventions and the quality of care but has rarely been quantified. Accordingly, we measured health status after discharge in an international registry (REPORT-HF) of AHF.

The analysis included 4606 patients with AHF who survived to hospital discharge, had known vital status at 6 months, and were enrolled in the United States of America, Russian Federation, or Western Europe, where the Kansas City Cardiomyopathy Questionnaire (KCCQ) was administered. PF-07220060 Median age was 69 years (quartiles 59-78), 40% were women, and 34% had a left ventricular ejection fraction (LVEF) <40%, and 12% patients died by 6 months. Of 2475 patients with a follow-up KCCQ, 28% were 'alive and well' (KCCQ >75), while 43% had poor health status (KCCQ ≤50). Being 'alive and well' was associated with new-onset AHF, LVEF <40%, younger age, higher baseline KCCQ, country, and race. Associations were similar for increasing health status, with the exception of country and addition of comorbidities.

In this international global registry, health status recovery after AHF hospitalisation was highly variable. Those with the best health status at 6months were younger, had new-onset heart failure, and higher baseline KCCQ; nearly one-third of survivors were 'alive and well'. Investigating reasons for changes in KCCQ after hospitalisation might identify new therapeutic targets to improve patient-centred outcomes.

To measure the infectious titre (IT) decay rate for various bacteriophages as a function of storage container material. Additionally, parallel light scattering and infectious titre measurements reveal distinct mechanisms for IT loss, depending on phage.

Suspensions of bacteriophages 44AHJD, P68 and gh-1 were stored in various labware. IT of each suspension was repeatedly measured over the course of 2 weeks. Large variability in IT decay was observed, with >4 log
loss in glass and low-binding polypropylene. Incubation of polymer containers with Bovine Serum Albumin (BSA) resulted in a consistent reduction in IT decay. Aggregation state of phage suspensions was studied by nanoparticle tracking analysis (NTA), revealing highest aggregation in glass-stored suspensions and lowest after storage in BSA-treated containers.

Glass and 'low-binding' containers may aggravate IT decay while BSA treatment may present an easy mitigation strategy. IT versus NTA titre diagrams highlight the importance of phage inactivation in combination with aggregation.

Container material is a significant determinant of bacteriophage IT decay. It is therefore essential to confirm IT following storage and tailor choice of phage storage containers accordingly. Aggregation of phages and adsorption onto labware surfaces are not only the mechanisms accounting for IT loss but also biological instability.
