Treadmill-based gait rehabilitation protocols have shown that real-time visual biofeedback can promote learning of improved gait biomechanics, but previous feedback work has largely involved treadmill walking and not overground gait. The objective of this study was to determine the short-term response to hip extension visual biofeedback, with individuals post-stroke, during unconstrained overground walking. Individuals post-stroke typically have a decreased paretic propulsion and walking speed, but increasing hip extension angle may enable the paretic leg to better translate force anteriorly during push-off. Fourteen individuals post-stroke completed overground walking, one 6-min control bout without feedback, and three 6-min training bouts with real-time feedback. Data were recorded before and after the control bout, before and after the first training bout, and after the third training bout to assess the effects of training. Visual biofeedback consisted of a display attached to eyeglasses that showed one horizontal bar indicating the user's current hip angle and another symbolizing the target hip extension to be reached during training. On average, paretic hip extension angle (p = 0.014), trailing limb angle (p = 0.025), and propulsion (p = 0.011) were significantly higher after training. Walking speed increased but was not significantly higher after training (p = 0.089). Individuals demonstrated a greater increase in their hip extension angle (p = 0.035) and propulsion (p = 0.030) after the walking bout with feedback compared to the control bout, but changes in walking speed did not significantly differ (p = 0.583) between a control walking bout and a feedback bout. Our results show the feasibility of overground visual gait feedback and suggest that feedback regarding paretic hip extension angle enabled many individuals post-stroke to improve parameters important for their walking function., (© 2023.

Background: Maternal depressive symptoms are common in pregnancy and may extend to the perinatal period and beyond for some women. To date, few longitudinal studies have investigated maternal depressive symptoms from pregnancy to eleven years postpartum. Drawing data from a large population-based study cohort the aims of this study were to 1) identify distinct groups of mothers defined by their trajectories of depressive symptoms spanning from pregnancy to eleven years following the birth of the child, and 2) to identify psychosocial risk factors during pregnancy and in the first few postnatal years that are associated with these trajectories., Methods: Data were analyzed from 14,170 mothers who participated in Avon Longitudinal Study of Parents and Children (ALSPAC). The Edinburgh Postnatal Depression Scale (EPDS) was used to capture maternal depressive symptoms across 10 time points including two prenatal (18 and 32 weeks), and eight postnatal (2, 8, 21, 33, 61, 73, 97 and 134 months) time points. The latent growth model was created to describe the course of maternal depressive symptoms across the preceding time points followed by a latent growth mixture modelling (LGMM) to identify distinct trajectories of depressive symptoms over time within the overall sample. The predictors of maternal depressive symptoms trajectories were categorized into sociodemographic, child, and psychosocial factors. The multinomial regression analyses were conducted to explore associations between the risk factors and depressive symptoms trajectories., Results: LGMM identified four distinct trajectories of maternal depressive symptoms over time: minimal symptoms, increasing symptoms, persistent symptoms, and decreasing symptoms. Predictors of all patterns of depression - persistent, increasing and decreasing symptoms include smoking during pregnancy, and partner conflict. The strongest predictors of the persistent symptom trajectory included maternal history of depression and inadequate social support., Limitations: The use of self-reported maternal mental health symptoms and under representation of ethnic minorities are our study's limitations., Conclusions: The study findings highlight the importance of early identification and treatment for mothers experiencing depressive symptoms from pregnancy to the perinatal period and beyond., Competing Interests: Conflict of interest None of the authors have any financial interest or benefit arising from the direct applications of this research study., (Copyright © 2023 Elsevier B.V.

Background: Visual biofeedback has shown success in improving gait mechanics in individuals post-stroke but has typically been restricted to use on a treadmill or a short walkway. Using real-time visual biofeedback during overground walking could increase the ease of clinical translation of this method. The objective was to investigate the reliability of a real-time hip extension feedback device during unconstrained, overground walking. We hypothesized that the peak hip extension angle outcome of our device would be comparable to peak hip extension angle measured from a common motion capture system. In addition, we hypothesized that individuals post-stroke would increase their hip extension angle after a single walking bout with visual biofeedback of their hip extension angle., Methods: Fourteen individuals with chronic stroke walked for one six-minute walking bout with the visual biofeedback device. Before (pre-training) and after (post-training) the feedback walking bout, participants walked in a straight line at their self-selected speed for at least five steps per foot., Findings: Our device was reliable in measuring peak hip extension angle when compared to 3D motion capture equipment (R 2  = 0.99). Individuals increased their hip extension angle after one session with the visual biofeedback (+2.886 ± 2.189 deg) compared to a control walking bout (+1.550 ± 1.629 deg) (Z = -2.103, p = 0.035)., Interpretation: Our novel and inexpensive biofeedback method may provide benefit for individuals post-stroke and expand the possibilities for feedback in rehabilitation., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Ltd.

Background and Aims: The World Health Organization's International Classification of Diseases (ICD-11) includes Compulsive Sexual Behavior Disorder (CSBD), a new diagnosis that is both controversial and groundbreaking, as it is the first diagnosis to codify a disorder related to excessive, compulsive, and out-of-control sexual behavior. The inclusion of this novel diagnosis demonstrates a clear need for valid assessments of this disorder that may be quickly administered in both clinical and research settings., Design: The present work details the development of the Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI) across seven samples, four languages, and five countries., Setting: In the first study, data were collected in community samples drawn from Malaysia (N = 375), the U.S. (N = 877), Hungary (N = 7,279), and Germany (N = 449). In the second study, data were collected from nationally representative samples in the U.S. (N = 1,601), Poland (N = 1,036), and Hungary (N = 473)., Findings: Across both studies and all samples, results revealed strong psychometric qualities for the 7-item CSBD-DI, demonstrating evidence of validity via correlations with key behavioral indicators and longer measures of compulsive sexual behavior. Analyses from nationally representative samples revealed residual metric invariance across languages, scalar invariance across gender, strong evidence of validity, and utility in classifying individuals who self-identified as having problematic and excessive sexual behavior, as evidenced by ROC analyses revealing suitable cutoffs for a screening instrument., Conclusion: Collectively, these findings demonstrate the cross-cultural utility of the CSBD-DI as a novel measure for CSBD and provide a brief, easily administrable instrument for screening for this novel disorder.

Introduction: Substantial research indicates that high quality early childhood education and care (ECEC) confers a wide range of benefits for children, yet quality in ECEC remains inconsistent. Given the variability in training and qualifications, one strategy for improving ECEC quality is in-service professional development (PD)., Methods: The current study evaluated an evidence-based in-service PD programme, Leadership for Learning, via a cluster randomised controlled trial involving 83 ECEC services and 1,346 children in their final year of pre-school., Results: Results indicated significant improvements in teaching quality across treatment centres and child development outcomes in language, numeracy and social-emotional development., Discussion: This study provides strong support for making evidence-informed PD routinely available for ECEC practitioners., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Siraj, Melhuish, Howard, Neilsen-Hewett, Kingston, De Rosnay, Huang, Gardiner and Luu.)

Background: Studies investigating the patterns or predictors of psychological distress in expecting and postpartum mothers affected by previous prenatal loss, are limited. The study objectives were to explore longitudinal trajectory patterns of depressive and anxiety symptoms in mothers affected by previous prenatal loss from early in a subsequent pregnancy up to pre-adolescence, and to identify early factors predictive of elevated symptom trajectory patterns., Methods: A total of 2854 mothers from the Avon Longitudinal Study of Parents and Children self-identified as having experienced a previous prenatal loss. A latent class analysis identified trajectory patterns of symptoms across 10 timepoints from 18-weeks' gestation up to 134-months postpartum, multivariate regression analysis identified predictors of elevated symptom trajectories, and hierarchical regression analysis determined predictive accuracy between predictors and elevated trajectory patterns., Results: Three distinct longitudinal trajectory patterns of depressive and anxiety symptoms reflected low (54%), sub-clinical (34%), and clinical symptoms (12%). Key factors that predicted elevated symptom trajectory patterns better than increased symptom scores early in subsequent pregnancy include history of severe depression or other psychiatric problem, experiencing three or more stressful events from mid-pregnancy, inadequate social support, history of induced abortion, and history of abuse. Predictive accuracy of elevated trajectories was 0.542 (depression) and 0.432 (anxiety)., Limitations: Generalizability may be compromised by attrition, under-reporting, and recall bias., Conclusion: Including factors predictive of long-term sub-clinical or clinical depressive and anxiety symptoms in early assessments will improve clinician's ability to identify mothers who may benefit from immediate and/or ongoing monitoring, and psychotherapeutic intervention after prenatal loss., (Copyright © 2022 Elsevier B.V.

Metal leachate from mine tailings has the potential to release toxic metals into the surrounding environment. A single-step extraction procedure mimicking rainwater and a three-step BCR sequential extraction procedure (acid, reducing and oxidizing conditions) were applied to gold (GMT) and silver (SMT) mine tailings. Major (Al, Ca, Fe, Mg, and Mn) and trace metals were monitored to better understand the mobility and geochemistry of these metals when exposed to various environmental leaching conditions. Rainwater extraction released only small quantities of metals, while the three-step BCR extraction was more effective in mobilizing metals from the tailings. Under the acidic conditions of BCR step 1, Ca, Mg, Cd, Cu, and Mn were released in high concentrations. The dissolution of Fe, Ca, and Mg were dominant along with Pb in step 2 (reducing conditions). In step 3 (oxidizing conditions), Fe was the most dominant species together with Co, Cu, Ni, and Se. A high fraction of Al, Be, Cr, Li, Mo, Sb, Tl, and V remained in the residue. From SMT, larger quantities of As, Ca, Cd, and Zn were released compared to GMT. The BCR extraction could be applied to tailings to predict the potential release of toxic metals from mine wastes; however, excessive amounts of Ca and Fe in the tailings could cause carry-overs and incomplete extraction and carry-overs, resulting in a misinterpretation of results., (© 2022.

Problem: While routine psychosocial assessment is acceptable to most pregnant women, some women will not fully disclose psychosocial concerns to their clinician., Aims: To assess the impact of psychosocial risk, current symptoms and mode of assessment on women's honesty of disclosure at psychosocial assessment., Methods: Logistic regression was used to examine associations between disclosure and a range of psychosocial characteristics in women who were 'always honest' and 'not always honest'. Mixed ANOVAs were used to test the influence of mode of assessment and honesty on scores on a repeated measure of psychosocial risk., Findings: 10.8% (N=193 of 1788) of women did not fully disclose at psychosocial assessment. Non-disclosure was associated with a mental health history (aOR=1.78, 95%CI: 1.18-2.67, p<0.01) and lack of social and partner support (aOR=1.74, 95%CI: 1.16-2.62, p<0.05; aOR=2.08, 95%CI: 1.11-3.90, p<0.05, respectively). Those reporting not always being honest at face to face assessment showed a greater increase in psychosocial risk score when the assessment was repeated online via self-report, compared to women who were always honest., Discussion: A history of mental health issues and lack of social and partner support are associated with reduced disclosure at face to face assessment. Online self-report assessment may promote greater disclosure, however this should always be conducted in the context of clinician feedback., Conclusion: Greater psychosocial vulnerability is associated with a lower likelihood of full disclosure. Preliminary findings relating to mode of assessment warrant further exploration within a clinical context., (Copyright © 2021 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Problem: Although perinatal universal depression and psychosocial assessment is recommended in Australia, its clinical performance and cost-effectiveness remain uncertain., Aim: To compare the performance and cost-effectiveness of two models of psychosocial assessment: Usual-Care and Perinatal Integrated Psychosocial Assessment (PIPA)., Methods: Women attending their first antenatal visit were prospectively recruited to this cohort study. Endorsement of significant depressive symptoms or psychosocial risk generated an 'at-risk' flag identifying those needing referral to the Triage Committee. Based on its detailed algorithm, a higher threshold of risk was required to trigger the 'at-risk' flag for PIPA than for Usual-Care. Each model's performance was evaluated using the midwife's agreement with the 'at-risk' flag as the reference standard. Cost-effectiveness was limited to the identification of True Positive and False Positive cases. Staffing costs associated with administering each screening model were quantified using a bottom-up time-in-motion approach., Findings: Both models performed well at identifying 'at-risk' women (sensitivity: Usual-Care 0.82 versus PIPA 0.78). However, the PIPA model was more effective at eliminating False Positives and correctly identifying 'at-risk' women (Positive Predictive Value: PIPA 0.69 versus Usual Care 0.41). PIPA was associated with small incremental savings for both True Positives detected and False Positives averted., Discussion: Overall PIPA performed better than Usual-Care as a psychosocial screening model and was a cost-saving and relatively effective approach for detecting True Positives and averting False Positives. These initial findings warrant evaluation of longer-term costs and outcomes of women identified by the models as 'at-risk' and 'not at-risk' of perinatal psychosocial morbidity., (Copyright © 2021 The Authors.

Problem: While comprehensive psychosocial assessment is recommended as part of routine maternity care, unless women engage and disclose, psychosocial risk will not be identified or referred in a timely manner. We need to better understand and where possible overcome the barriers to disclosure if we are to reduce mental health morbidity and complex psychosocial adversity., Aims: To assess pregnant women's attitude to, and reasons for non-disclosure at, comprehensive psychosocial assessment with their midwife., Methods: Data from 1796 pregnant women were analysed using a mixed method approach. After ascertaining women's comfort with, attitude to, and non-disclosure at psychosocial screening, thematic analysis was used to understand the reasons underpinning non-disclosure., Findings: 99% of participants were comfortable with the assessment, however 11.1% (N = 193) reported some level of nondisclosure. Key themes for non-disclosure included (1) Normalising and negative self-perception, (2) Fear of negative perceptions from others, (3) Lack of trust of midwife, (4) Differing expectation of appointment and (5) Mode of assessment and time issues., Discussion: Factors associated with high comfort and disclosure levels in this sample include an experienced and skilled midwifery workforce at the study site and a relatively advantaged and mental health literate sample. Proper implementation of psychosocial assessment policy; setting clear expectations for women and, for more vulnerable women, extending assessment time, modifying mode of assessment, and offering continuity of midwifery care will help build rapport, improve disclosure, and increase the chance of early identification and intervention., Conclusions: This study informs approaches to improving comprehensive psychosocial assessment in the maternity setting., (Copyright © 2021 The Authors.
