Mother-infant interaction and infant development in women at risk of postpartum psychosis with and without a postpartum relapse.

BACKGROUND: This study aimed to investigate mother-infant interaction and infant development in women at-risk of postpartum psychosis (PP), with and without a postpartum relapse. METHODS: 103 women (and their offspring) were included, 43 at-risk-of-PP because of a diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 60 with no current/previous mental illness or family history of PP. Of the at-risk women, 18 developed a psychiatric relapse within 4 weeks after delivery (AR-unwell), while 25 remained symptom-free (AR-well). Mother-infant interaction was assessed using the CARE-Index at 8 weeks' and 12 months' postpartum and infant development using the Bayley-III at 12 months' postpartum. RESULTS: Women at-risk-of-PP as a group, regardless of whether they developed a psychiatric relapse within 4 weeks after delivery, had less synchronous mother-infant interactions and had infants with less optimal cognitive, language, motor and socio-emotional development than healthy controls. In particular, boys of at-risk women had the lowest scores in cognitive, language and motor development and in mother-infant interaction, while girls of the at-risk women had the lowest scores in socio-emotional development. The synchrony in the dyad predicted infant cognitive and language development. There was no evidence for a difference in mother-infant interaction nor in infant development between the AR-unwell and AR-well groups. CONCLUSIONS: These results suggest that, while there is a lack of evidence that an early postpartum relapse in women at-risk-of-PP could represent a risk for the infant per se, maternal risk for PP may be associated with less optimal mother-infant interaction and infant development.

Women with depression in pregnancy or a history of depression have decreased quality of mentalization in the speech to their infants.

BACKGROUND: Our study aims to understand whether depression, either in pregnancy or lifetime, affects cognitive biases (comprising the attentional focus and affective state) and mentalizing features (ability to understand children's internal mental states, thereby detecting and comprehending their behavior and intention), in maternal speech during mother-infant interaction in the first postnatal year. METHODS: We recruited 115 pregnant women (44 healthy, 46 with major depressive disorder [MDD] in pregnancy, and 25 with a history of MDD but healthy pregnancy) at 25 weeks' gestation. Three-minute videos were recorded at 8 weeks and 12 months postnatally for each dyad. Maternal speech was transcribed verbatim and coded for cognitive biases and mentalizing comments using the Parental Cognitive Attributions and Mentalization Scale (PCAMs). RESULTS: Women suffering from antenatal depression showed a decreased proportion of mentalizing comments compared with healthy women, at both 8 weeks (0.03 ± 0.01 vs. 0.07 ± 0.01, P = 0.002) and 12 months (0.02 ± 0.01 vs. 0.04 ± 0.01, P = 0.043). Moreover, compared with healthy women, both those with antenatal depression and those with a history of depression showed decreased positive affection in speech (0.13 ± 0.01 vs. 0.07 ± 0.01 and 0.08 ± 0.02, respectively P = 0.003 and P = 0.043), and made significantly fewer comments focused on their infants' experience at 8 weeks (0.67 ± 0.03 vs. 0.53 ± 0.04 and 0.49 ± 0.05, respectively P = 0.015 and P = 0.005). In linear regression models women's socioeconomic difficulties and anxiety in pregnancy contribute to these associations, while postnatal depression did not. CONCLUSIONS: Both antenatal depression and a lifetime history of depression are associated with a decreased quality of women's speech to their infants, as shown by less focus on their infant's experience, decreased positive affection, and less able to mentalize. Examining maternal speech to their infants in the early postnatal months may be particularly relevant to identify women who could benefit from strategies addressing these aspects of the interactive behavior and thus improve infant outcome in the context of depression.

Clinical application and feasibility of utilizing the PEDI-CAT to assess activity and participation among children receiving physical therapy incorporating hippotherapy.

BACKGROUND: Hippotherapy (HPOT) is a physical therapy (PT) treatment tool using equine movement to improve mobility for children with movement impairments. Although research suggests HPOT improves body structure and function, there is limited evidence regarding its impact on activity and participation outcomes in a clinical setting. The Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT) may be useful in HPOT settings to highlight changes in activity and participation. PURPOSE: 1) Evaluate the PEDI-CAT's sensitivity to changes in activity and participation among children receiving PT using HPOT; 2) determine feasibility of administering the PEDI-CAT in a HPOT setting; and 3) examine how PEDI-CAT scores influence clinical decision-making. METHODS: Participants (N = 34) were children who attended weekly PT using HPOT for 6 months. The PEDI-CAT was completed for all participants by a parent or caregiver at initial treatment (T1) and 6 months later (T2). A linear mixed effects model was used to evaluate changes in scores over time. Team meetings occurred monthly to discuss how PEDI-CAT scores impacted treatment. RESULTS: There were significant improvements across 3 PEDI-CAT domains between T1 and T2 for all children with small effect sizes and nonsignificant changes noted within two diagnostic subgroups with small-to-medium effect sizes. The PEDI-CAT was completed by all participants without interrupting treatment flow. PEDI-CAT score reports enriched therapist-client conversations increasing shared decision-making. CONCLUSION: PTs who treat children using HPOT may feasibly use the PEDI-CAT to assess changes in activity level outcomes and to assist clinical decision-making.

National Network of Depression Centers' Recommendations on Harmonizing Clinical Documentation of Electroconvulsive Therapy.

ABSTRACT: Electroconvulsive therapy (ECT) is a highly therapeutic and cost-effective treatment for severe and/or treatment-resistant major depression. However, because of the varied clinical practices, there is a great deal of heterogeneity in how ECT is delivered and documented. This represents both an opportunity to study how differences in implementation influence clinical outcomes and a challenge for carrying out coordinated quality improvement and research efforts across multiple ECT centers. The National Network of Depression Centers, a consortium of 26+ US academic medical centers of excellence providing care for patients with mood disorders, formed a task group with the goals of promoting best clinical practices for the delivery of ECT and to facilitate large-scale, multisite quality improvement and research to advance more effective and safe use of this treatment modality. The National Network of Depression Centers Task Group on ECT set out to define best practices for harmonizing the clinical documentation of ECT across treatment centers to promote clinical interoperability and facilitate a nationwide collaboration that would enable multisite quality improvement and longitudinal research in real-world settings. This article reports on the work of this effort. It focuses on the use of ECT for major depressive disorder, which accounts for the majority of ECT referrals in most countries. However, most of the recommendations on clinical documentation proposed herein will be applicable to the use of ECT for any of its indications.

Baseline Predictors of Response to Repetitive Task Practice in Chronic Stroke.

BACKGROUND: Repetitive task practice reduces mean upper extremity motor impairment in populations of patients with chronic stroke, but individual response is highly variable. A method to predict meaningful reduction in impairment in response to training based on biomarkers and other data collected prior to an intervention is needed to establish realistic rehabilitation goals and to effectively allocate resources. OBJECTIVES: To identify prognostic factors and better understand the biological substrate for reductions in arm impairment in response to repetitive task practice among patients with chronic (≥6 months) post-stroke hemiparesis. METHODS: The intervention is a form of repetitive task practice using a combination of robot-assisted therapy and functional arm use in real-world tasks. Baseline measures include the Fugl-Meyer Assessment, Wolf Motor Function Test, Action Research Arm Test, Stroke Impact Scale, questionnaires on pain and expectancy, MRI, transcranial magnetic stimulation, kinematics, accelerometry, and genomic testing. RESULTS: Mean increase in FM-UE was 4.6 ± 1.0 SE, median 2.5. Approximately one-third of participants had a clinically meaningful response to the intervention, defined as an increase in FM ≥ 5. The selected logistic regression model had a receiver operating curve with AUC = .988 (Std Error = .011, 95% Wald confidence limits: .967-1) showed little evidence of overfitting. Six variables that predicted response represented impairment, functional, and genomic measures. CONCLUSION: A simple weighted sum of 6 baseline factors can accurately predict clinically meaningful impairment reduction after outpatient intensive practice intervention in chronic stroke. Reduction of impairment may be a critical first step to functional improvement. Further validation and generalization of this model will increase its utility in clinical decision-making.

Increased maternal inflammation and poorer infant neurobehavioural competencies in women with a history of major depressive disorder from the psychiatry research and motherhood - Depression (PRAM-D) study.

INTRODUCTION: Stress in pregnancy is associated with adverse outcomes in offspring, and developmental programming is a potential mechanism. We have previously shown that depression in pregnancy is a valid and clearly defined stress paradigm, and both maternal antenatal and offspring stress-related biology is affected. This study aims to clarify whether maternal biology in pregnancy and offspring outcomes can also be influenced by a history of a prior depression, in the absence of depression in pregnancy. Our primary hypothesis is that, similarly to women with depression in pregnancy, women with a history of depression but who are not depressed in pregnancy will have increased cortisol secretion and markers of immune system function, and that their offspring will have poorer neuro-developmental competencies and increased cortisol stress response. METHODS: A prospective longitudinal design was used in 59 healthy controls and 25 women with a past history of depression who were not depressed in pregnancy, named as 'history-only', and their offspring. Maternal antenatal stress-related biology (cortisol and markers of immune system function) and offspring outcomes (gestational age at birth, neonatal neurobehaviour (Neonatal Behavioural Assessment Scale, NBAS), cortisol stress response and basal cortisol at 2 and 12 months) and cognitive, language and motor development (Bayley Scales of Infant and Toddler Development (BSID)) were measured. RESULTS: Compared with healthy pregnant women, those with a history of depression who remain free of depression in pregnancy exhibit increased markers of immune system function in pregnancy: IL-8 (d = 0.63, p = 0.030), VEGF (d = 0.40, p = 0.008) and MCP-1 (d = 0.61, p = 0.002) and have neonates with lower neurobehavioural scores in most areas, reaching statistical significance in thesocial-interactive (d = 1.26, p = 0.015) cluster. However, there were no differences in maternal or offspring HPA axis function or in infant development at 12 months. CONCLUSION: Our study indicates that pregnant women with a history of depression have increased markers of immune system function, and their offspring show behavioural alterations that may be the effects of in utero programming, epigenetic factors or genetic predisposition.

Neuromodulation Strategies for the Treatment of Depression.

For many decades, psychiatric treatment has been primarily guided by two major paradigms of psychopathology: a neurochemical paradigm leading to the development of medications and a psychological paradigm resulting in the development of psychotherapies. A third paradigm positing that psychiatric dysfunction results from abnormal communication within a network of brain regions that regulate mood, thought, and behavior has gained increased attention over the past several years and underlies the development of multiple neuromodulation and neurostimulation therapies. This neural circuit paradigm is not new. In the late 19th and early 20th centuries, it was a common way of understanding psychiatric illness and led to several of our earliest somatic therapies. However, with the rise of effective medications and evidence-based psychotherapies, this paradigm went mostly dormant. Its recent reemergence resulted from a growing recognition that medications and psychotherapy leave many patients inadequately treated, along with technological advances that have revolutionized our ability to understand and modulate the neural circuitry involved in psychiatric disorders. In this overview, the authors review the history and current state of neuromodulation for psychiatric illness and specifically focus on these approaches as a treatment for depression, as this has been the primary indication for these interventions over time.

Maternal perceived bonding towards the infant and parenting stress in women at risk of postpartum psychosis with and without a postpartum relapse.

BACKGROUND: Postpartum psychosis (PP) is the most severe psychiatric disorder associated with childbirth. However, there is little research on maternal bonding towards the infant and parenting stress in this clinical population. METHODS: We investigated maternal bonding during pregnancy and post-partum in 75 women: 46 at risk of PP (AR), because of a DSM-IV diagnosis of bipolar disorder, schizoaffective disorder or previous PP, and 29 healthy controls. Of the AR women, 19 developed a psychiatric relapse within 4 weeks' post-partum (AR-unwell), while 27 remained symptom-free (AR-well). We investigated childhood maltreatment, parenting stress and psychiatric symptoms as potential predictors of maternal bonding. RESULTS: In pregnancy, AR-unwell women reported a more negative affective experience towards their infants than AR-well women (d = 0.87, p = .001), while postnatally there was no significant difference in bonding. In contrast, AR women as a group reported a more negative affective experience than HC postnatally (d = 0.69, p = .002; d = 0.70, p = .010), but not antenatally. Parenting stress and psychiatric symptoms significantly predicted less optimal postnatal bonding (b = -0.10, t = -4.29, p < .001; b = -0.37, t = -4.85, p < .001) but only psychiatric symptoms explained the difference in bonding between AR and HC (b = -1.18, 95% BCa CI [-2.70,-0.04]). LIMITATIONS: A relatively small sample size precluded a more in-depth investigation of underlying pathways. CONCLUSION: This study provides new information on maternal bonding in women at risk of PP, and particularly in those that do and do not develop a postpartum relapse. The results suggest that improving maternal symptoms and parenting stress in the perinatal period in women at risk of PP could also have positive effects on bonding.

Altered dynamics of the prefrontal networks are associated with the risk for postpartum psychosis: a functional magnetic resonance imaging study.

Postpartum psychosis (PP) is a severe mental disorder that affects women in the first few weeks after delivery. To date there are no biomarkers that distinguish which women at risk (AR) develop a significant psychiatric relapse postpartum. While altered brain connectivity may contribute to the risk for psychoses unrelated to the puerperium, this remains unexplored in PP. We followed up 32 AR and 27 healthy (HC) women from pregnancy to 8-week postpartum. At this point, we classified women as AR-unwell (n = 15) if they had developed a psychiatric relapse meeting DSM-IV diagnostic criteria, or impacting on daily functioning and requiring treatment, or AR-well (n = 17) if they remained asymptomatic. Women also underwent an fMRI scan at rest and during an emotional-processing task, to study within- and between-networks functional connectivity. Women AR, and specifically those in the AR-well group, showed increased resting connectivity within an executive network compared to HC. During the execution of the emotional task, women AR also showed decreased connectivity in the executive network, and altered emotional load-dependent connectivity between executive, salience, and default-mode networks. AR-unwell women particularly showed increased salience network-dependent modulation of the default-mode and executive network relative to AR-well, who showed greater executive network-dependent modulation of the salience network. Our finding that the executive network and its interplay with other brain networks implicated in goal-directed behavior are intrinsically altered suggest that they could be considered neural phenotypes for postpartum psychosis and help advance our understanding of the pathophysiology of this disorder.

Mother-infant interaction in women with depression in pregnancy and in women with a history of depression: the Psychiatry Research and Motherhood - Depression (PRAM-D) study.

BACKGROUND: Little is known about the effects of depression before birth on the quality of the mother-infant interaction. AIMS: To understand whether depression, either in pregnancy or in lifetime before pregnancy, disrupts postnatal mother-infant interactions. METHOD: We recruited 131 pregnant women (51 healthy, 52 with major depressive disorder (MDD) in pregnancy, 28 with a history of MDD but healthy pregnancy), at 25 weeks' gestation. MDD was confirmed with the Structured Clinical Interview for DSM-IV Disorders. Neonatal behaviour was assessed at 6 days with the Neonatal Behavioural Assessment Scale, and mother-infant interaction was assessed at 8 weeks and 12 months with the Crittenden CARE-Index. RESULTS: At 8 weeks and 12 months, dyads in the depression and history-only groups displayed a reduced quality of interaction compared with healthy dyads. Specifically, at 8 weeks, 62% in the depression group and 56% in the history-only group scored in the lowest category of dyadic synchrony (suggesting therapeutic interventions are needed), compared with 37% in the healthy group (P = 0.041); 48% and 32%, respectively, scored the same at 12 months, compared with 14% in the healthy group (P = 0.003). At 6 days, neonates in the depression and history-only groups exhibited decreased social-interactive behaviour, which, together with maternal socioeconomic difficulties, was also predictive of interaction quality, whereas postnatal depression was not. CONCLUSIONS: Both antenatal depression and a lifetime history of depression are associated with a decreased quality of mother-infant interaction, irrespective of postnatal depression. Clinicians should be aware of this, as pregnancy provides an opportunity for identification and intervention to support the developing relationship.

Risk factors for postpartum relapse in women at risk of postpartum psychosis: The role of psychosocial stress and the biological stress system.

BACKGROUND: Postpartum psychosis is the most severe psychiatric disorder associated with childbirth, and the risk is particularly high for women with a history of bipolar disorder, schizoaffective disorder or those who have suffered a previous episode of postpartum psychosis. Whilst there is a lot of evidence linking stress to psychosis unrelated to childbirth, the role of stress in the onset of postpartum psychosis has not been fully investigated. METHODS: A prospective longitudinal study of 112 pregnant women, 51 at risk of postpartum psychosis because of a DSM-IV diagnosis of bipolar disorder (n = 41), schizoaffective disorder (n = 6) or a previous postpartum psychosis (n = 4) and 61 healthy women with no past or current DSM-IV diagnosis and no family history of postpartum psychosis. Women were followed up from the third trimester of pregnancy to 4 weeks' post partum. Women at risk who had a psychiatric relapse in the first 4 weeks' post partum (AR-unwell) (n = 22), were compared with those at risk who remained well (AR-well) (n = 29) on measures of psychosocial stress (severe childhood maltreatment and stressful life events) and biological stress (cortisol and inflammatory biomarkers). RESULTS: Logistic regression analyses revealed that severe childhood maltreatment (OR = 4.9, 95% CI 0.5-49.2) and higher daily cortisol in the third trimester of pregnancy (OR=3.7, 95% CI 1.2-11.6) predicted psychiatric relapse in the first 4 weeks' post partum in women at risk of postpartum psychosis after adjusting for clinical and sociodemographic covariates. CONCLUSION: The current study provides evidence for the role of psychosocial stress and the biological stress system in the risk of postpartum relapse in women at risk of postpartum psychosis.

Comparing Home Upper Extremity Activity with Clinical Evaluations of Arm Function in Chronic Stroke.

OBJECTIVE: To determine if clinical evaluations of post-stroke arm function correspond to everyday motor performance indexed by arm accelerometers. DESIGN: Cross-sectional study analyzing baseline data from a larger trial (NCT02665052). SETTING: Outpatient research center. PARTICIPANTS: Twenty community-dwelling adults with chronic arm motor deficits (stroke≥6mo). INTERVENTION: 72-hours of home wrist-worn accelerometry during normal routine. MAIN OUTCOME MEASURES: Clinical evaluations included the Fugl-Meyer (FM), Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), and two self-assessments: the Motor Activity Log (MAL) and hand motor subscale of the Stroke Impact Scale (SIS). Accelerometer-derived variables included quantifications of movement intensity (magnitude) and duration of arm use. RESULTS: Participants had moderate arm impairment (FM 36.1 ± 9.4). The accelerometer-derived mean magnitude ratio correlated significantly with the FM (ρ = 0.60, p < 0.01), WMFT functional score (ρ = 0.59, p < 0.01), and ARAT (ρ = 0.50, p < 0.05). The hours of use ratio correlated with the MAL amount of use (ρ = 0.58, p < 0.01) and quality of movement (ρ = 0.61, p < 0.01). Total paretic hours did not correlate with the FM, WMFT or ARAT, and intensity variables did not correlate with the MAL or SIS. CONCLUSIONS: Participants with higher baseline function had greater intensity of paretic arm movement at home; similarly, those who perceived they had less disability used their paretic arm more relative to their non-paretic arm. However, some participants with higher clinical scores did not exhibit greater arm use in everyday life, possibly due to neglect and learned non-use. Therefore, individualized home accelerometry profiles could provide valuable insight to better tailor post-stroke rehabilitation.

Depression Comorbid With Stroke, Traumatic Brain Injury, Parkinson's Disease, and Multiple Sclerosis: Diagnosis and Treatment.

Depression is common among patients with neurologic disorders, and it has long been considered more difficult to treat than depression in the general population. In this review, the authors consider challenges in the diagnosis and treatment of depression among patients with stroke, traumatic brain injury, Parkinson's disease, and multiple sclerosis. For each disorder, the authors discuss the epidemiology and time course of depression as well as review the physiologic and psychological etiologies of depression. In addition, for each disorder, they review screening tools and diagnostic considerations, including differential diagnosis; discuss etiological factors, both neurobiological and psychological; and assess evidence for various depression treatments, including pharmacologic, psychosocial, and neuromodulatory therapies. The evidence suggests that depression is common among patients with neurologic disorders and that it is crucial for general psychiatrists to provide treatment for this population.

Acceptability and outcomes of an individualized exergaming telePT program for veterans with multiple sclerosis: a pilot study.

BACKGROUND: Physical rehabilitation services are an important component of treatment for persons with multiple sclerosis (PwMS) to improve and maintain physical mobility. However, PwMS often have significant barriers to outpatient physical therapy (PT) services including mobility deficits and lack of transportation. The integration of exercise gaming (exergaming) and telehealth into clinical PT practices may overcome these barriers. The overarching purpose of this pilot study was to evaluate the acceptability and effects of an individualized telePT intervention using exergaming. METHODS: Ten individuals with multiple sclerosis (MS) completed a 12-week exergaming (Jintronix®) telerehabilitation intervention. In order to measure the acceptability of the telerehabilitation intervention, adherence was measured through the tablet-based rehabilitation software and each participant completed a satisfaction questionnaire. Clinical outcome measures were assessed at baseline and post-intervention. To evaluate the efficacy of this intervention, the following measures of physical function and fatigue were included; the Short Physical Performance Battery (SPPB), 25-Foot Walk (25FW), Modified Fatigue Impact Scale (MFIS), Multiple Sclerosis Walking Scale-12 (MSWS), and the 2-Minute Walk Test (2MWT). Clinical outcomes were analyzed using the Sign test and Wilcoxon signed rank test. All other data were evaluated using descriptive statistics. RESULTS: After the intervention, participants demonstrated significant improvements in ambulation speed during the 25FW (p = 0.04) and ambulation distance during the 2MWT (p = 0.002). Statistically significant increases of SPPB total score (p = .04) and sub-scores were also found. Participants did not demonstrate significant changes in the MFIS (p = 0.31) or MSWS-12 (p = 0.06) after the intervention. Participants had a 58.3% adherence rate during the intervention and performed their exercise program an average of 2.5 times per week. All participants reported that they were either 'satisfied or 'very satisfied' with their telerehabilitation experience, would use telerehabilitation again, and would recommend telerehabilitation to others. CONCLUSION: This individualized telerehabilitation intervention which integrates exergaming and clinical video teleconferencing is acceptable to patients and may offer a viable alternative to traditional PT for PwMS. TRIAL REGISTRATION: NCT03655431, retrospectively registered on August 31st, 2018.

Functional network connectivity in early-stage schizophrenia.

Schizophrenia is a disorder of altered neural connections resulting in impaired information integration. Whole brain assessment of within- and between-network connections may determine how information processing is disrupted in schizophrenia. Patients with early-stage schizophrenia (n = 56) and a matched control sample (n = 32) underwent resting-state fMRI scans. Gray matter regions were organized into nine distinct functional networks. Functional connectivity was calculated between 278 gray matter regions for each subject. Network connectivity properties were defined by the mean and variance of correlations of all regions. Whole-brain network measures of global efficiency (reflecting overall interconnectedness) and locations of hubs (key regions for communication) were also determined. The control sample had greater connectivity between the following network pairs: somatomotor-limbic, somatomotor-default mode, dorsal attention-default mode, ventral attention-limbic, and ventral attention-default mode. The patient sample had greater variance in interactions between ventral attention network and other functional networks. Illness duration was associated with overall increases in the variability of network connections. The control group had higher global efficiency and more hubs in the cerebellum network, while patient group hubs were more common in visual, frontoparietal, or subcortical networks. Thus, reduced functional connectivity in patients was largely present between distinct networks, rather than within-networks. The implications of these findings for the pathophysiology of schizophrenia are discussed.

Biological stress response in women at risk of postpartum psychosis: The role of life events and inflammation.

BACKGROUND: Postpartum psychosis (PP) is the most severe psychiatric disorder associated with childbirth, and the risk is particularly high in women with a history of bipolar disorder, schizoaffective disorder or in those who have suffered previous episodes of PP. While studies in patients with psychosis not related to the puerperium have demonstrated that abnormalities in stress response are important risk factors for psychosis, it remains unknown whether this is also the case for PP. METHODS: This study includes 30 postpartum women, assessed, on average, at postpartum week 14.8 ± 10.1 either with a current episode of PP (n = 14), or at-risk of PP because of a history of bipolar/schizoaffective disorder but who were well (n = 16), and a group of healthy women (n = 26). Details about recent stressful life events were obtained using the List of Threatening Experiences questionnaire, while perceived stress was evaluated using the Perceived Stress Scale. We estimated hypothalamic-pituitary adrenal (HPA) activity by measuring salivary cortisol at awakening; at 15, 30, and 60 min after awakening; at noon; and at 8 pm. An Area Under the Curve analysis was performed to assess the awakening response (AUCi) and cortisol levels during the day (AUCg). Immune markers, including high sensitivity C-Reactive Protein (hs-CRP) and Interleukin (IL)-1a, IL-1b, IL-2, IL-4, IL-6, IL-8, IL-10, Tumor Necrosis Factor (TNFa), Vascular Endothelial Growth Factor (VEGF), Interferon gamma (INFγ), Monocyte Chemoattractant Protein 1 (MCP-1), and Epidermal Growth Factor (EGF) were evaluated from peripheral blood samples. RESULTS: Women with current PP reported more frequent recent stressful life events, and higher perceived stress than healthy women. They also showed an activation of the stress and immune response, with higher levels of cortisol AUCg and hs-CRP (but not of other inflammatory markers) than healthy controls. Women at-risk of PP who remained well had values on these measures that were intermediate between those of women with a current episode of PP and those of healthy women. Stress measures and markers of stress and immune response explained 78 % of the variance of in group status between PP and healthy women, and 46 % of variance of in group status between women at-risk and healthy women. CONCLUSION: These findings suggest that an immune-HPA axis dysregulation, together with current stress may represent an important underlying pathophysiological mechanism in the onset of psychosis after childbirth in vulnerable women.

Robot-Assisted Arm Training in Chronic Stroke: Addition of Transition-to-Task Practice.

Background. Robot-assisted therapy provides high-intensity arm rehabilitation that can significantly reduce stroke-related upper extremity (UE) deficits. Motor improvement has been shown at the joints trained, but generalization to real-world function has not been profound. Objective. To investigate the efficacy of robot-assisted therapy combined with therapist-assisted task training versus robot-assisted therapy alone on motor outcomes and use in participants with moderate to severe chronic stroke-related arm disability. Methods. This was a single-blind randomized controlled trial of two 12-week robot-assisted interventions; 45 participants were stratified by Fugl-Meyer (FMA) impairment (mean 21 ± 1.36) to 60 minutes of robot therapy (RT; n = 22) or 45 minutes of RT combined with 15 minutes therapist-assisted transition-to-task training (TTT; n = 23). The primary outcome was the mean FMA change at week 12 using a linear mixed-model analysis. A subanalysis included the Wolf Motor Function Test (WMFT) and Stroke Impact Scale (SIS), with significance P <.05. Results. There was no significant 12-week difference in FMA change between groups, and mean FMA gains were 2.87 ± 0.70 and 4.81 ± 0.68 for RT and TTT, respectively. TTT had greater 12-week secondary outcome improvements in the log WMFT (-0.52 ± 0.06 vs -0.18 ± 0.06; P = .01) and SIS hand (20.52 ± 2.94 vs 8.27 ± 3.03; P = .03). Conclusion. Chronic UE motor deficits are responsive to intensive robot-assisted therapy of 45 or 60 minutes per session duration. The replacement of part of the robotic training with nonrobotic tasks did not reduce treatment effect and may benefit stroke-affected hand use and motor task performance.

Methods for an Investigation of Neurophysiological and Kinematic Predictors of Response to Upper Extremity Repetitive Task Practice in Chronic Stroke.

OBJECTIVE: To demonstrate the feasibility of algorithmic prediction using a model of baseline arm movement, genetic factors, demographic characteristics, and multimodal assessment of the structure and function of motor pathways. To identify prognostic factors and the biological substrate for reductions in arm impairment in response to repetitive task practice. DESIGN: This prospective single-group interventional study seeks to predict response to a repetitive task practice program using an intent-to-treat paradigm. Response is measured as a change of ≥5 points on the Upper Extremity Fugl-Meyer from baseline to final evaluation (at the end of training). SETTING: General community. PARTICIPANTS: Anticipated enrollment of community-dwelling adults with chronic stroke (N = 96; onset≥6mo) and moderate to severe residual hemiparesis of the upper limb as defined by a score of 10-45 points on the Upper Extremity Fugl-Meyer. INTERVENTION: The intervention is a form of repetitive task practice using a combination of robot-assisted therapy coupled with functional arm use in real-world tasks administered over 12 weeks. MAIN OUTCOME MEASURES: Upper Extremity Fugl-Meyer Assessment (primary outcome), Wolf Motor Function Test, Action Research Arm Test, Stroke Impact Scale, questionnaires on pain and expectancy, magnetic resonance imaging, transcranial magnetic stimulation, arm kinematics, accelerometry, and a saliva sample for genetic testing. RESULTS: Methods for this trial are outlined, and an illustration of interindividual variability is provided by example of 2 participants who present similarly at baseline but achieve markedly different outcomes. CONCLUSION: This article presents the design, methodology, and rationale of an ongoing study to develop a predictive model of response to a standardized therapy for stroke survivors with chronic hemiparesis. Applying concepts from precision medicine to neurorehabilitation is practicable and needed to establish realistic rehabilitation goals and to effectively allocate resources.
