Intensive circuit class therapy in patients with relapsing-remitting multiple sclerosis
Long-term physiotherapy is of considerable benefit to patients with motor dysfunction or gait impairment in patients with multiple sclerosis (MS). The aim of this study was to determine the effectiveness of 12-week intensive circuit class therapy (ICT) for patients with MS, with a wider focus on fatigue and gait ability. Methods: A total of 46 relapsing-remitting MS patients were divided randomly: Twenty-three of them (mean Expanded Disability Status Scale (EDSS) 2.33±0.74) took part in an intensive 12-week course of ICT and 23 (mean EDSS 2.04±0.63) served as a control group. The EDSS, Timed Up and Go (TUG) test and Four-Stage Balance Test (FSBT) made up the physical testing part, supplemented by questionnaires such as the Modified Fatigue Impact Scale (MFIS), 12-Item Multiple Sclerosis Walking Scale (MSWS-12), Beck Depression Inventory (BDI) and 36-Item Short Form Survey (SF-36).
Actions of a Shaken Heart: Interoception Interacts with Action Processing
In the present study, we investigated the modulatory influence of the unconscious, bodily arousal on motor-related embodied information. Specifically, we examined how the interoceptive prediction error interacts with the event-related potentials linked to action-effect processing. Participants were asked to perform a task with self-initiated or externally-triggered sounds while receiving synchronous or false auditory cardiac feedback. The results found that interaction of interoceptive manipulation and action-effect processing modulates the frontal subcomponent of the P3 response. During the synchronous cardiac feedback, the P3 response to self-initiated tones was enhanced. During the false cardiac feedback, the frontal cortical response was reversed. N1 and P2 components were affected by the interoceptive manipulation, but not by the interaction of interoception and action processing.
Risk factors for depression and anxiety in painful and painless diabetic polyneuropathy: A multicentre observational cross-sectional study
Background: Despite the high prevalence of depression and anxiety in chronic pain conditions, current knowledge concerning emotional distress among painful diabetic polyneuropathy (pDSPN) and other diabetes mellitus (DM) sufferers is limited.
Methods: This observational multicentre cohort study employed the Hospital Anxiety and Depression Scale, the Beck Depression Inventory II and the State-Trait Anxiety Inventory to assess symptoms of depression and anxiety in several groups with diabetes, as well as in a control group. The study cohort included 347 pDSPN patients aged 63.4 years (median), 55.9% males; 311 pain-free diabetic polyneuropathy (nDSPN) patients aged 63.7 years, 57.9% males; 50 diabetes mellitus (DM) patients without polyneuropathy aged 61.5 years, 44.0% males; and 71 healthy controls (HC) aged 63.0 years, 42.3% males.
Human iPSC-Derived Neural Models for Studying Alzheimer's Disease: from Neural Stem Cells to Cerebral Organoids
During the past two decades, induced pluripotent stem cells (iPSCs) have been widely used to study mechanisms of human neural development, disease modeling, and drug discovery in vitro. Especially in the field of Alzheimer's disease (AD), where this treatment is lacking, tremendous effort has been put into the investigation of molecular mechanisms behind this disease using induced pluripotent stem cell-based models. Numerous of these studies have found either novel regulatory mechanisms that could be exploited to develop relevant drugs for AD treatment or have already tested small molecules on in vitro cultures, directly demonstrating their effect on amelioration of AD-associated pathology. This review thus summarizes currently used differentiation strategies of induced pluripotent stem cells towards neuronal and glial cell types and cerebral organoids and their utilization in modeling AD and potential drug discovery.
The reduction of hippocampal volume in Parkinson's disease
The volume of the hippocampus decreases more slowly than the volume of the cortex during normal aging. We explored changes in the hippocampus-to-cortex volume (HV:CTV) ratio with increasing age in non-demented Parkinson's disease (PD) patients as compared to healthy controls (HC). We also evaluated the association between the HV:CTV ratio and cognitive outcomes. Altogether 130 participants without dementia aged 51-88 years were consecutively enrolled, including 54 PD patients (mean age 67, standard deviation (SD) 8 years) and 76 HC (mean age 69, SD 7 years). All participants underwent structural magnetic resonance examination and psychological evaluation. Hippocampal and cortex volumes were determined from T1 and FLAIR scans using FreeSurfer software, and the HV:CTV ratio was calculated. Regression lines for age-dependence of the HV:CTV ratio for PD and HC groups were calculated.
Between-Center Variation in Outcome After Endovascular Treatment of Acute Stroke: Analysis of Two Nationwide Registries
Background: Insight in differences in patient outcomes between endovascular thrombectomy (EVT) centers can help to improve stroke care. We assessed between-center variation in functional outcome of patients with acute ischemic stroke who were treated with EVT. We analyzed to what extent this variation may be explained by modifiable center characteristics.
Methods: We used nationwide registry data of patients with stroke treated with EVT in the Netherlands and in the Czech Republic. Primary outcome was modified Rankin Scale score at 90 days as an indicator of disability. We used multilevel ordinal logistic regression to quantify the between-center variation in outcomes and the impact of patient and center characteristics.
Emergency cesarean section is a risk factor for depressive symptoms when breastfeeding is limited
Objective: Previous studies indicated associations between cesarean section (CS), breastfeeding, and depressive symptoms. There is, however, little research integrating these variables into one model to analyze their interrelations. The aim of this observational prospective longitudinal study is to examine whether the effect of CS on postpartum depressive symptoms is mediated by difficulties with breastfeeding.
Methods: The participants were recruited in 5 maternity hospitals during their prenatal medical check-ups. Breastfeeding status was self-reported by the mothers six weeks postpartum. Screening for depressive symptoms was performed at six weeks (N = 404) and nine months (N = 234) postpartum using the Edinburgh Postnatal Depression Scale.
Is the vertex a good control stimulation site? Theta burst stimulation in healthy controls
The vertex has been used as a suitable control stimulation site in repetitive transcranial magnetic stimulation studies. The objectives of this study are (1) to assess cognitive performance (CP) after theta burst stimulation (TBS); (2) to evaluate whether clinically relevant cortical areas might be reached by vertex stimulation and how that might influence CP. Twenty young healthy subjects performed a cognitive task prior to and immediately after intermittent TBS (iTBS) and continuous TBS (cTBS) of two active cortical stimulation sites and the vertex. We used the Wilcoxon signed-rank test to compare the pre- and post-stimulation reaction times (RTs) and a mixed ANOVA analysis to evaluate the effect of the stimulation on changes in RTs.
