Objective Social Security Disability is a common external incentive in neuropsychological evaluations. This study determined base rates of invalidity when patients referred for routine clinical evaluations have Social Security Disability as an external incentive. Method Patients (n = 242) were grouped as validly or invalidly performing based on the use of multiple performance validity tests. Frequency analyses were then conducted. Results As a whole, 46.0% of clinically referred patients with Social Security Disability as an external incentive produced invalid data. When divided by disability pursuit status, 58.6% of individuals already receiving Social Security Disability, 44.6% of individuals actively seeking Social Security Disability, and 39.3% of individuals considering seeking Social Security Disability produced invalid data. By comparison, only 8.5% of clinically referred patients without known external incentives produced invalid data. Conclusions Beyond establishing base rates, these data indicate that the external incentive, not necessarily the evaluation setting, increases the rate of invalidity, as obtained base rates mirror those observed in independent medical examinations. In addition, this study highlights that even patients who report that they are considering but have not committed themselves to pursuing an external incentive frequently invalidate testing.Transcranial direct current stimulation (tDCS) is a novel treatment option for major depression which could be provided as a first-line treatment. tDCS is a non-invasive form of transcranial stimulation which changes cortical tissue excitability by applying a weak (0.5-2 mA) direct current via scalp electrodes. Anodal and cathodal stimulation leads to depolarisation and hyperpolarisation, respectively, and cumulative effects are observed with repeated sessions. The montage in depression most often involves anodal stimulation to the left dorsolateral prefrontal cortex. Rates of clinical response, remission, and improvements in depressive symptoms following a course of active tDCS are greater in comparison to a course of placebo sham-controlled tDCS. In particular, the largest treatment effects are evident in first episode and recurrent major depression, while minimal effects have been observed in treatment-resistant depression. The proposed mechanism is neuroplasticity at the cellular and molecular level. Alterations in neural responses have been found at the stimulation site as well as subcortically in prefrontal-amygdala connectivity. A possible mediating effect could be cognitive control in emotion dysregulation. Additional beneficial effects on cognitive impairments have been reported, which would address an important unmet need. The tDCS device is portable and can be used at home. Clinical trials are required to establish the efficacy, feasibility and acceptability of home-based tDCS treatment and mechanisms.

The aim of this study was to assess the characteristics of mitral annular plane systolic excursion (MAPSE) in different longitudinal directions in normal fetuses using a new method, automatic cardiac motion quantification (aCMQ).

A cross-sectional study was conducted in 164 fetuses with structurally normal hearts. RP6306 The time-displacement curves of the septal mitral annulus (SMA) in three directions, including point A, B and C (MAPSE-SMA-A, MAPSE-SMA-B, MAPSE-SMA-C), were recorded by aCMQ. The time to peak (TTP) in three directions, including point A, B and C (TTP-SMA-A, TTP-SMA-B, TTP-SMA-C) were recorded. In the same way, various parameters of the lateral mitral annulus (LMA) were obtained including MAPSE-LMA-A, MAPSE-LMA-B, MAPSE-LMA-C, TTP-LMA-A, TTP-LMA-B and TTP-LMA-C. Free angle M-mode echocardiography (FAM) was used to obtain MAPSE of LMA (FAM-MAPSE). Finally, all the data were analyzed statistically.

MAPSE was positively correlated with gestational age, and the difference between the second- and tmovement of the fetal mitral annulus is comprehensive, with multiple directions and different displacements. Perpendicular to the mitral annulus is the maximum displacement. It is positively related to the gestational age. From the second trimester, the longitudinal contraction of the left ventricle wall has good synchronization. It possesses clinical value in selecting different methods and parameters during evaluating left ventricular function.

Evaluate the safety and efficacy of a subcutaneous insulin (SC-I) versus intravenous insulin (IV-I) protocol for optimizing maternal blood glucose levels (BGLs) post-betamethasone administration.

Randomized controlled in-patient pilot study in pregnant women with diabetes, excluding type 1 diabetes, receiving betamethasone ≥24 weeks’ gestation. Interventions were stratified SC-I and IV-I protocols, titrated to hourly BGLs (IV-I) or predicted maternal hyperglycemia and 2-4 hourly BGLs (SC-I). Primary outcome was percentage at-target BGL 4.0-8.0 mmol/L over 48 h post-betamethasone. Secondary outcomes were rates of maternal hyperglycemia (>8.0 mmol/L), hypoglycemia (<4.0 mmol/L) and neonatal hypoglycemia (≤2.5 mmol/L).

19 women (3 with type 2 diabetes [T2DM], 4 with gestational diabetes [GDM]-diet, 12 GDM-insulin) were randomized to a SC-I (

 = 13) or IV-I (

 = 6) protocol in a 9-month period. There was a non-significant trend for higher mean percentage at-target BGLs with SC-I vs IV-I (87% vs 81%;

 = .055); this was significant when the cohort was restricted to women with GDM (89% vs 81%;

 = .04). Maternal hyperglycemia (85% vs 100%;

 = .31) and hypoglycemia (54% vs 33%;

 = .41) were not significantly different, but there were no BGLs <3.8 mmol/L with IV-I (vs 4 women with SC-I;

 = .13). The rate of neonatal hypoglycemia was not different between groups.

A SC-I or IV-I protocol controls maternal BGLs following betamethasone, but SC-I appears safe and minimizes labor intensive IV-I in GDM. An adequately powered RCT to assess superiority of SC-I is planned.
