The use of health apps is increasing worldwide, with a common feature being daily symptom tracking. However, symptom tracking has been shown to increase symptom reporting. This study investigated whether using a menstrual-monitoring app with a symptom-tracking feature increases symptom reporting compared to an app without this feature or no app at all.

Experimental study.

Ninety-one participants were randomly allocated to use either a menstrual-monitoring app with a symptom tracker or a simple calendar app, or to a no app control group. The number of period-related symptoms as well as general symptom reporting was assessed at baseline prior to group allocation and then 1 and 4months later. The change in the proportion of people classified as high symptom reporters was also examined.

We found that the symptom-tracking app group reported significantly more period-related symptoms at 4months than the calendar app group (mean difference=1.16 symptoms, p=.010). At the 4-month time point, significantly moren to result in greater symptom reporting, symptom severity, and slower recovery from injury. The use of health apps is increasing, with a common feature being symptom tracking. Menstrual-monitoring apps, in particular, frequently require users to track symptoms. 1-PHENYL-2-THIOUREA What does this study add? Using a menstrual-monitoring app with a symptom tracker for 4 months increases the number of period-specific symptoms reported compared a basic calendar app. A greater proportion of people were now classified as high period symptom reporters after using the symptom-tracking app. These effects do not seem to generalize to broader non-specific symptom reporting.
Amyloid peptides Aβ40 and Aβ42, whose deposition in brain correlates with Alzheimer disease, are also present in platelets and have prothrombotic activities.

In this study, we analyze the ability of Aβ peptides to form fibrils and to induce platelet activation and aggregation.

Aβ40, Aβ42, and their scrambled peptides were diluted in phosphate buffered saline and fibrillogenesis was investigated by ThioflavinT and Congo Red. Aggregation, protein phosphorylation, and reactive oxygen species (ROS) production were analyzed.

Aβ40 and Aβ42, but not scrambled peptides, were able to form fibrils when diluted in phosphate buffered saline. Fibrillogenesis of Aβ42 was very rapid, whereas fibril formation by Aβ40 was completed only after 48hours of incubation. Fibrillar Aβ40 and Aβ42 promoted dose-dependent aggregation of washed platelets in the presence of extracellular CaCl
. Cleavage of GPIbα by mocarhagin or blockade of the ITAM-containing FcγRIIA prevented platelet aggregation induced by fibrillary Aβ40 and Aβ42. Fibrillar Aβ peptides stimulated the phosphorylation of FcγRIIA, resulting in the downstream stimulation of PLC, protein kinase C, and phosphoinositide 3-kinases, whose activity was necessary for full aggregation of platelets. Fibrillar Aβ peptides also induced ROS generation, and NOX inhibitors, as well as ROS scavengers, prevented platelet aggregation. However, Aβ peptide-induced ROS production did not require binding to GPIbα or activation of FcγRIIA, but was initiated by CD36, which provided an important contribution to full platelet aggregation.

These results suggest that fibrillar amyloid Aβ40 and Aβ42 induce platelet aggregation through the recruitment of GPIb-IX-V and CD36, which requires the convergence of ITAM- and ROS-dependent pathways.

Presently, there is a lack of valid and reliable instruments to obtain the perspective of patients with suicidal ideation regarding their contact with professionals in mental health wards. This was a three-stage study to develop and psychometrically evaluate a questionnaire the Contact with Nurses from the perspective of Patients with Suicidal ideation (CoNuPaS). First, the construct was defined by a systematic review, qualitative study, and face validity among experts. Second, the content was validated through a Delphi procedure with professional experts (n = 14) and cognitive interviews with hospitalized patients (n = 12). Third, using a sample of adult patients with suicidal ideation in the past year (n = 405), the psychometric properties were assessed by an exploratory factor analysis, a test-retest procedure, and the internal consistency. The CoNuPaS comprises 23 items and two subsections, to examine patients' perceptions of contact experiences with nurses (CoNuPaS-experience) and what they find important in that contact (CoNuPaS-importance). The subsections comprise four components encountering a space to express suicidal thoughts and explore needs, being recognized as a unique and self-determining individual, encountering nurses' availability/information-sharing/transparency on expectations, and trusting nurses in communication about suicidality. Content validity scores were excellent (0.78-1.00); test-retest intraclass correlation coefficient and internal consistency were >0.90. Thus, the CoNuPaS demonstrated good psychometric properties. The availability of a valid questionnaire to examine patient-nurse contact in mental health wards is central to improving understanding of nurses' contributions to suicide prevention and suicidal ideation treatment.Despite progress in engineering both vascularized tissues and oriented tissues, the fabrication of 3D vascularized oriented tissues remains a challenge due to an inability to successfully integrate vascular and anisotropic structures that can support mass transfer and guide cell alignment, respectively. More importantly, there is a lack of an effective approach to guiding the scaffold design bearing both structural features. Here, an approach is presented to optimize the bifurcated channels within an anisotropic scaffold based on oxygen transport simulation and biological experiments. The oxygen transport simulation is performed using the experimentally measured effective oxygen diffusion coefficient and hydraulic permeability of the anisotropic scaffolds, which are also seeded with muscle precursor cells and cultured in a custom-made perfusion bioreactor. Symmetric bifurcation model is used as fractal unit to design the channel network based on biomimetic principles. The bifurcation level of channel network is further optimized based on the oxygen transport simulation, which is then validated by DNA quantification assay and pimonidazole immunostaining.
