The implementation of a national micronutrient survey will be beneficial in informing policy and practice aimed at reducing the prevalence of child malnutrition in line with national targets, through improvement in dietary intake.This report describes the rationale, purpose and design of A011801 (CompassHER2 RD), an ongoing prospective, multicenter, phase III randomized trial. Eligible patients in the United States (US) and Canada with high-risk (defined as ER-negative and/or node-positive) HER2-positive (HER2+) residual disease (RD) after a predefined course of neoadjuvant chemotherapy and HER2-directed treatment are randomized 11 to adjuvant T-DM1 and placebo, versus T-DM1 and tucatinib. Patients have also received adjuvant radiotherapy and/or endocrine therapy, if indicated per standard of care guidelines. The primary objective of the trial is to determine if the invasive disease-free survival (iDFS) with T-DM1 plus tucatinib is superior to iDFS with T-DM1 plus placebo; other outcomes of interest include overall survival (OS), breast cancer-free survival (BCFS), distant recurrence-free survival (DRFS), brain metastases-free survival (BMFS) and disease-free survival (DFS). Correlative biomarker, quality of life (QoL) and pharmacokinetic (PK) endpoints are also evaluated.

There have been no studies evaluating the usefulness of grayscale radiographs in extremity fractures. We aimed to compare the ability and reliability of traction radiographs vs traction grayscale inversion radiographs to detect fracture fragment and comminution zones in comminuted tibia pilon fractures.

Plain radiographs and grayscale inversion images of 60 patients with Orthopaedic Trauma Association/AO Foundation type C3 fracture were evaluated by 20 observers (15 orthopedic surgeons and 5 radiologists) after traction had been applied. The anterolateral, posterolateral, and medial malleolar fragments, as well as the lateral, central, and medial column comminution zones, were identified by all physicians. Computed tomography scan images were used as the "gold standard" against which plain radiographs and grayscale inversion image interpretation were measured. Intra- and interobserver reliability and correct identification of fracture fragments and comminution zones were evaluated.

The interobserver reliability for 3 of the fracture fragments and comminution zones on the traction plain radiographs was moderate, whereas it was substantial on traction grayscale inversion radiographs. The lateral comminution zones (

= .001) and presence or absence of posterolateral fragments (

< .001) were significantly better identified in grayscale inversion radiographs compared to standard radiographs.

After traction was applied, we found grayscale inversion radiographs are superior to plain radiographs in the identification of posterolateral fragment and lateral zone of comminution in comminuted intraarticular pilon fractures.

III, Retrospective Case Series.The Washington Assessment of the Risks and Needs of Students (WARNS) is a computer-based assessment created to help courts, schools, and youth service providers determine an adolescent's risks and needs that may lead to truancy, drop out, or delinquency from school. Users are advised to consider the WARNS total score to work with youth. A total score estimate based on fewer items than the full item set may result in less respondent burden, administration time, and fatigue, while not hindering accurate decisions. This simulation study examined the applicability and efficiency of a computerized adaptive test (CAT) to estimate a WARNS total score under a unidimensional item response theory model. The results demonstrate that the CAT provides an accurate estimate of students' risks and needs and reduces the number of items administered for each examinee compared with the existing version. Future directions and limitations of CAT development with the WARNS are discussed.

In the light of the ongoing replication crisis in the field of neuroimaging it is necessary to assess the possible exogenous and endogenous factors, that may affect functional magnetic resonance imaging (fMRI). The current project investigated time-of-day effects in the spontaneous fluctuations (<0.1Hz) of the blood oxygenation level dependent (BOLD) signal.

Using data from the human connectome project (HCP) release S1200, cross-spectral density dynamic causal modelling (DCM) was used to analyze time-dependent effects on the hemodynamic response and effective connectivity parameters. The DCM analysis covered three networks, namely the default mode network (DMN), the central executive network (CEN), and the saliency network (SN). Hierarchical group-parametric empirical Bayes (PEB) was used to test varying design-matrices against the time-of-day model.

Hierarchical group-parametric empirical Bayes (PEB) found no support for changes in effective connectivity, whereas the hemodynamic parameters exhibited a significant time-of-day dependent effect, indicating a diurnal vascular effect that might affect the measured BOLD signal in the absence of any diurnal variations of the underlying neuronal activations and effective connectivity.

We conclude that these findings urge the need to account for the time of data acquisition in future MRI studies and suggest that time-of-day dependent metabolic variations contribute to reduced reliability in resting-state fMRI studies.

To quantify the presence of conflicts of interest (COI) in SRs and MAs of Ménières disease treatment and identify any related secondary characteristics of these articles.

A search was conducted on May 28, 2020 to search MEDLINE and Embase databases for SRs or MAs pertaining to Ménières disease published between September 1, 2016 and June 2, 2020. A risk of bias assessment was performed using the Cochrane Collaboration risk of bias assessment criteria.

A total of 13 systematic reviews conducted by 49 authors met the inclusion criteria. Of the 49 authors, 7 (14.3%) were found to have some form of COI. Of these 7 authors, 1 (14.3%) completely disclosed all COI within the SR, 1 (14.3%) disclosed one or more COI but were found to have an additional undisclosed COI, and 5 (71.4%) were found to have only undisclosed COI. One of 2 industry funded SRs (50%) had a high risk of bias, and 1 (50%) of the non-industry sponsored SRs were found to have a high risk of bias.

Overall authors of SRs pertaining to Ménières disease appear to be properly disclosing COI at higher rates than other fields of medicine; however, further room for improvement has been noted.

Hypomethylating agents (HMAs), azacitidine and decitabine, are standard of care therapy for higher-risk myelodysplastic syndromes. However, outcomes reported for real-world studies fall short of those achieved in clinical trials. We conducted a targeted literature review exploring real-world utilization, persistence and outcomes with intravenous and subcutaneous HMA therapies to better understand barriers to achieving optimal outcomes in clinical practice. The potential benefits of oral HMA therapy were also explored. Underutilization and poor persistence with HMA therapy are associated with suboptimal outcomes, highlighting the need for approaches to improve utilization and persistence, so that patients achieve the optimum benefit from HMA therapy.

Despite advances in and increased adoption of technology, glycemic outcomes for individuals with type 1 diabetes (T1D) have not improved. Access to care is limited for many, in part due to a shortage of endocrinologists and their concentration in urban areas. Managing T1D via telehealth has potential to improve glycemic outcomes, as the barriers of travel-related time and cost are mitigated.

Our endocrine telehealth program started in 2013 and currently provides care to nine rural community hospitals in Nebraska and Iowa. BTK inhibitor nmr A retrospective cohort study was performed to evaluate glycemic outcomes in people with T1D who received care at these telehealth clinics from 2013-2019. Data were collected on age, race, gender, prior diabetes provider, use of diabetes technology, and A1c values over time.

One hundred thirty-nine individuals were followed for an average duration of 32 months (range 4-69 months). Sixty-six percent of people were previously under the care of an endocrinologist. The most common therapeutic action, in addition to insulin adjustment, was addition of a CGM (52%). Each year in telemedicine care was associated with a decline of 0.13% in A1c (95% CI -0.20, -0.06). There was no association between A1c and age or gender. When stratifying by previous diabetes provider, all groups had a statistically significant decline in A1c, even those with a previous endocrine provider. There was no statistically significant decline in A1c based on addition of technology.

We have shown that traditional telehealth visits are an effective way to provide care for people with T1D long-term and may provide distinct advantages to home telehealth visits.

This case report describes a 47-year-old female patient with low-grade astrocytoma who was initiated on low-dose dexamethasone for symptom management. The patient developed joint pain 1 year after steroid exposure, then was found to have AVN of the hip followed by multiple other joints. This case report highlights the extent to which AVN can occur in patients with brain tumors following a short course of low-dose corticosteroids. Careful evaluation of and monitoring for the development of AVN should occur frequently in patients with brain tumors given the frequent use of corticosteroids for symptom management in this population.The formation of dense protein interfacial layers at a free air-water interface is known to result from both diffusion and advection. Furthermore, protein interactions in concentrated phases are strongly dependent on their overall positive or negative net charge, which is controlled by the solution pH. As a consequence, an interesting question is whether the presence of an advection flow of water toward the interface during protein adsorption produces different kinetics and interfacial structure of the adsorbed layer, depending on the net charge of the involved proteins and, possibly, on the sign of this charge. Here we test a combination of the following parameters using ovalbumin and lysozyme as model proteins positive or negative net charge and the presence or absence of advection flow. The formation and the organization of the interfacial layers are studied by neutron reflectivity and null-ellipsometry measurements. We show that the combined effect of a positive charge of lysozyme and ovalbumin and the presence of advection flow does induce the formation of interfacial multilayers.
