The Australian Health Economics Model of Osteoporosis (AusHEMO) has shown good face, internal and cross validities, and can be used to assist healthcare decision-making in Australia.
This study aimed to document and validate the risk engine of the Australian Health Economics Model of Osteoporosis (AusHEMO).

AusHEMO is a state-transition microsimulation model. The fracture risks were simulated using fracture incidence rates from the Dubbo Osteoporosis Epidemiology Study. The AusHEMO was validated regarding its face, internal and cross validities. Goodness-of-fit analysis was conducted and Lin's coefficient of agreement and mean absolute difference with 95% limits of agreement were reported.

The development of AusHEMO followed general and osteoporosis-specific health economics guidelines. AusHEMO showed good face validity regarding the model's structure, evidence, problem formulation and results. In addition, the model has been proven good internal and cross validities in goodness-of-fit test. Lin's coefficluded. Health policy-makers in Australia can use the AusHEMO to select which osteoporosis interventions such as medications and public health interventions represent good value for money.Overweight/obesity, prevalent cardiovascular risk factors in children, can be associated with increased risk of adverse outcomes in children with heart disease. The American College of Cardiology (ACC) developed quality metrics including a BMI metric related to identifying and counseling overweight and obese children presenting to cardiology clinics. This metric was used for a multicenter collaborative learning Quality improvement (QI) Project through the ACC Quality Network (QNet). Our aim was to increase the percentage of children between ages 3 and 18 years presenting to cardiology clinics at participating centers with BMI > 85th percentile who received appropriate counseling. Participating centers submitted data quarterly to QNet for a sample of patients who received counseling. A Key Driver Diagram was created to help teams drive improvement. Individual centers customized interventions and participated in network-wide educational learning sessions about QI and shared experience. Statistical process control charts were used. From 04/01/2017 to 09/30/2019, 27,511 patient visits were included. Among 32 participating centers, overall counseling rate was 54%. The BMI counseling rate increased from 25% in 2017Q2 to 54% in 2019Q3. There was a wide variation from 10 to 100% in the performance of individual centers. The overall rate of identification and counseling of overweight and obese children presenting to ambulatory cardiology clinics in participating centers is low. There is wide variation in the performance of centers, providing an opportunity for improvement. Using this multicenter learning approach, individual centers have demonstrated improvement. This demonstrates that collaborative learning approaches in QI can increase implementation of the metric.Pulmonary artery hypertension (PAH) is a common and serious disease which is characterized by pulmonary vascular remodeling. Bosentan (BST) is the first approved oral targeted drug of endothelin-1 (ET-1) receptor antagonists for the treatment of PAH. MicroRNA-27a (miR-27a) and peroxisome proliferator-activated receptor γ (PPARγ) were found to be related to the pathogenesis of PAH. To further explore the signal transduction mechanism of BST in the treatment of PAH, we examined the effects of BST on endothelin receptors, miR-27a, and PPARγ. Meanwhile, the influence of miR-27a in the formation and development of PAH was discussed. Aloxistatin Our results demonstrated that during the pathophysiology of PAH, miR-27a, PPARγ, and ET-1 were cross-inhibited, which indicated that the miR-27a/PPARγ/ET-1 signaling pathway was dysregulated; in addition, BST could competitively bind to ET-1 receptors and inhibit the miR-27a/PPARγ/ET-1 signaling pathway, thereby delaying the proliferation of PASMCs and affecting the development of PAH. Our results give a new understanding of the pathogenesis and treatment of PAH and provide more reliable evidence for the application of BST in the treatment of PAH in the clinic.We sought to perform a comprehensive review of reported cases of conjoined thoracopagus twins with cardiovascular conjunction to determine the overall survival after separation and factors that might be associated with survival. We performed a systematic review of cases of thoracopagus twins with conjoined cardiovascular systems reported in the English medical literature using Embase, PubMed, Web of Science, and Scopus. We employed standard statistical methods to analyze differences among groups. We identified 102 unique cases of thoracopagus twins (69% female) with some degree of cardiovascular conjunction who had undergone surgical separation. We identified 6 distinct types of cardiovascular union. Median age was 47 days (IQR 12, 120). Survival to at least hospital discharge occurred in 51% (105/204). Median age at separation was lower in emergent (9 days, IQR 1, 25) versus elective cases (93 days, IQR 49, 180) (p  less then  0.0001). Survival to hospital discharge was higher in those who underwent elective separation (70%, 93/132 total children versus 17%, 12/72) (p  less then  0.0001). Survival was associated with the type of cardiovascular union (p  less then  0.0001). link2 The separation of thoracopagus twins with cardiovascular conjunction is higher than expected. Increased survival is associated with elective separation, older age, and shared pericardium only. These findings suggest survival could be improved with better delineation of degree of union and delayed separation.Knowing the normal values of left ventricular (LV) systolic synchronicity in the early neonatal period is very important for understanding myocardial function. This retrospective study analyzed data of 105 newborns who were examined using real-time 3-dimensional echocardiography (RT3DE). The time to the point of minimal regional systolic volume (Tmsv) was measured from volume-time curves in each segment. Standard deviation (SD) and maximal difference (Dif) of Tmsv were calculated from 16 (6 basal/6 mid/4 apical), 12 (6 basal/6 mid), and 6 (basal) LV segments with the corresponding parameters adjusted for the R-R interval. Influences of age, sex, gestational age, birth weight, and heart rate on parameters were explored. Data showed no significant difference among Tmsv-16-SD, Tmsv-12-SD, and Tmsv-6-SD. A strong correlation was found between Tmsv-6-SD and Tmsv-6-Dif (r = 0.83, P  less then  0.001), Tmsv-12-SD and Tmsv-6-SD (r = 0.77, P  less then  0.001), and Tmsv-12-Dif and Tmsv-6-Dif (r = 0.76, P  less then  0.001) and a moderate correlation was found between Tmsv-16-SD and Tmsv-16-Dif (r = 0.66, P  less then  0.001), Tmsv-6-SD and Tmsv-12-Dif (r = 0.62, P  less then  0.001), and Tmsv-12-SD and Tmsv-6-Dif (r = 0.61, P  less then  0.001). Heart rate correlated negatively with Tmsv (r = - 0.03 to - 0.11, P  less then  0.004-0.000), but had no effect on parameters adjusted for %R-R. Age, sex, gestational age, and birth weight did not affect any of these parameters. Tmsv-Dif and Tmsv-SD measured from 16 segments using RT3DE are useful as possible parameters for evaluating LV systolic synchronicity in normal newborns.Virtual reality (VR) is a relatively new technology that allows an individual to experience a virtual world. This new immersive video type may be of particular usefulness in procedure-based healthcare settings. We hypothesized that VR echocardiography was non-inferior to live demonstration. Our aim was to assess the usefulness of a VR echocardiographic approach in teaching echocardiography to pediatric trainees compared to live demonstration. This was a single center, cross-sectional observational design. We used a Garmin VIRB® 360 and a head-mount display to record live echocardiography exams in a pediatric population. An Oculus Go™ was used to view the 360° immersive/VR videos. Trainees responded to a written questionnaire afterwards. Fifteen trainees participated in the study, each of whom had previously seen echocardiography through live demonstration teaching. Eleven respondents had previous hands-on echocardiography experience. All 15 participants confirmed that VR echocardiography is a useful teaching tool with 87% (n = 13) rating it as good or very good on a 5-point Likert scale. When asked to compare VR to live demonstration, 67% (n = 10) rated VR echocardiography as the same or better than live demonstration. One of the participants reported a side effect, namely mild and self-resolving dizziness. VR echocardiography is a safe, inexpensive and practical way for trainees to learn echocardiography. link3 The addition of VR echocardiography to the arsenal of teaching tools may enrich the learning experience for trainees.
Bullying behaviours and other conduct problems often co-occur. However, we do not yet know whether bullying behaviours are associated with early factors and later poor outcomes independently of conduct problems. While there are differing, specific interventions for bullying behaviours and for conduct problems, it is unclear if such specificity is justified given parallels between both behaviours.

We used prospective data from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative sample of 2232 children. Mothers and teachers reported on children's bullying behaviours and conduct problems at ages 7 and 10. We collected measures of risk factors, including temperament and family factors, when children were age 5. We assessed behavioural, emotional, educational and social problems when participants reached the ages of 12 and 18.

Bullying behaviours and conduct problems co-occurred in childhood. Our findings indicated that bullying behaviours and other conduct problems were independently associated with the same risk factors. Furthermore, they were associated with the same poor outcomes at both ages 12 and 18. Despite this, bullying behaviours were uniquely associated with behavioural, emotional, educational and social problems at age 18.

Our findings suggest that anti-bullying programmes and interventions aimed at reducing conduct problems could benefit from greater integration. Furthermore, our study highlights the mental health problems children who bully may face in later years and the need to consider those in intervention plans.

Results showed an order of magnitude increase in time for Cd, therefore, no general average value was established. For V, however, results of this study suggest a general average value of 1.4 µg L-1 for the area. The observed spatial variation of concentrations could be the result of (1) temporal variation of external inputs to the area, and coincide with previously reported hydrodynamic patterns of dispersion related to significant river contributions and accumulation areas indicative of eddy circulation or fronts. The Perdido area showed Cd and V concentrations in surface water reflective of anthropogenic impacts, while its spatial and temporal variation could depend significantly on the hydrodynamics of the area.
