The effect of counseling with a skills training approach on maternal functioning: a randomized controlled clinical trial

BACKGROUND: The role of the mother can be deeply satisfying, but it is associated with many challenges including challenges during the postpartum period that may impede the optimal development of the infant. Therefore, the aim of the present study was to investigate the effects of counseling using the Skills Training Approach (STA) on postpartum maternal functioning. METHODS: This randomized controlled trial was performed on 68 postpartum women who referred to health centers of Tabriz-Iran in 2019. Participants were assigned to one of two groups - either counseling or control through the block randomization method. The intervention group received four counseling sessions using the Skills Training Approach (STA). Before and two weeks after the completion of the intervention, the Barkin Index of Maternal Functionning (BIMF) was completed by the participants. The independent t-test and ANCOVA (Analysis of Covariance) was used to analyze the data. RESULTS: There was no statistically significant difference between the two groups in terms of sociodemographic characteristics and the baseline scores of the BIMF and its domains (p\u2009>\u20090.05). Before the intervention, the mean (SD) total score of the BIMF in the intervention group was 73.1 (8.5) and in the control group, it was 71.6 (4.8). Post-intervention, the mean (SD) of the total score of the BIMF in the intervention group was 95.8 (11.8) and in the control group, it was 70.3 (4.5). Based on the ANCOVA test and after adjusting the baseline score, the mean total score of the BIMF was significantly higher in the intervention group than in the control group (Mean Difference (MD): 22.9; 95% CI: 18.2 to 27.6; p\u2009<\u20090.001). The post-intervention scores of all domains of the BIMF including self-care (MD: 3.8), infant care (MD: 2.0), mother-child interaction (MD: 4.8), psychological wellbeing (MD: 8.4), social support (MD: 4.0), management (MD: 6.8), and adjustment to new motherhood (MD: 3.2) were significantly higher in the intervention group compared to the control group (P\u2009<\u20090.001). CONCLUSION: In this study, counseling, using STA, was effective in improving maternal functioning in all of the domains. This intervention, aimed at skill-building, should be strongly considered where improved postpartum functioning is the goal

Estimating permeability and its scale dependence at pore scale using renormalization group theory

Investigating hydraulic and petrophysical properties of porous media has been an active area of research. Despite numerous progress in modeling flow and transport over the past decades, we are still far from accurately estimating the scale dependence of soil and rock properties. In this study, we propose applying renormalization group theory (RGT) at the pore scale. Using the RGT, we determine the scale dependence of effective pore-throat radius (rteff) and develop two theoretical models to estimate permeability (k) in pore networks of various sizes. The first theoretical model estimates k(L) from the rteff(L) and simulated formation factor F(L), while the second model uses information at the smallest scale (L = Lmin) in addition to rteff(L) and F(L). By comparing with 25 pore-network simulations, we show that the RGT estimates the scale-dependent k reasonably well. The first model estimates k(L) with average relative errors ranged between −53.1% and −3.0%, while the second model between −1.0% and 14.33%. We also conduct fluid flow simulations in 40 other pore networks above the representative elementary volume and compare the results of the RGT with those of the effective-medium approximation (EMA). Results showed that both RGT and EMA accurately estimate k from pore-throat radius distribution and formation factor with root mean square log-transformed error = 0.119 and 0.096, respectively

Spatio-Temporal Analysis of Drought Vulnerability using the Standardized Precipitation Index (Case study: Semnan Province, Iran)

This study was conducted to identify drought event and its emerging regions in Markazi desert, Iran with focus onSemnan province in a 30 years statistical period. In this research, 61 stations having adequate data selected and usedafter extracting annual statistic from monthly and daily data. Standardized precipitation index values for each stationwere calculated and classified. The Results have shown that there was drought condition in 17 studied stations. Alsoamong 44 stations with no drought condition, there was one humid year in 20 cases. Khareh sarlazor station has thefirst position of drought and humid condition among other stations, with 10 drought years and 5 humid years. Thenumber of common years with normal condition is 3 years and the most extensive drought in 1999 has occurred in 10dry stations and 1 very dry station. The existence of common trend of variation using study of correlation amongstations has resulted in determination of 7 groups which these results can be useful according to temporal distance ofone or two years in appearing drought in the same group of stations

Incomplete evidence that increasing current intensity of tDCS boosts outcomes

BACKGROUND: Transcranial direct current stimulation (tDCS) is investigated to modulate neuronal function by applying a fixed low-intensity direct current to scalp. OBJECTIVES: We critically discuss evidence for a monotonic response in effect size with increasing current intensity, with a specific focus on a question if increasing applied current enhance the efficacy of tDCS. METHODS: We analyzed tDCS intensity does-response from different perspectives including biophysical modeling, animal modeling, human neurophysiology, neuroimaging and behavioral/clinical measures. Further, we discuss approaches to design dose-response trials. RESULTS: Physical models predict electric field in the brain increases with applied tDCS intensity. Data from animal studies are lacking since a range of relevant low-intensities is rarely tested. Results from imaging studies are ambiguous while human neurophysiology, including using transcranial magnetic stimulation (TMS) as a probe, suggests a complex state-dependent non-monotonic dose response. The diffusivity of brain current flow produced by conventional tDCS montages complicates this analysis, with relatively few studies on focal High Definition (HD)-tDCS. In behavioral and clinical trials, only a limited range of intensities (1-2 mA), and typically just one intensity, are conventionally tested; moreover, outcomes are subject brain-state dependent. Measurements and models of current flow show that for the same applied current, substantial differences in brain current occur across individuals. Trials are thus subject to inter-individual differences that complicate consideration of population-level dose response. CONCLUSION: The presence or absence of simple dose response does not impact how efficacious a given tDCS dose is for a given indication. Understanding dose-response in human applications of tDCS is needed for protocol optimization including individualized dose to reduce outcome variability, which requires intelligent design of dose-response studies

Beyond the target area: an integrative view of tDCS-induced motor cortex modulation in patients and athletes

Transcranial Direct Current Stimulation (tDCS) is a non-invasive technique used to modulate neural tissue. Neuromodulation apparently improves cognitive functions in several neurologic diseases treatment and sports performance. In this study, we present a comprehensive, integrative review of tDCS for motor rehabilitation and motor learning in healthy individuals, athletes and multiple neurologic and neuropsychiatric conditions. We also report on neuromodulation mechanisms, main applications, current knowledge including areas such as language, embodied cognition, functional and social aspects, and future directions. We present the use and perspectives of new developments in tDCS technology, namely high-definition tDCS (HD-tDCS) which promises to overcome one of the main tDCS limitation (i.e., low focality) and its application for neurological disease, pain relief, and motor learning/rehabilitation. Finally, we provided information regarding the Transcutaneous Spinal Direct Current Stimulation (tsDCS) in clinical applications, Cerebellar tDCS (ctDCS) and its influence on motor learning, and TMS combined with electroencephalography (EEG) as a tool to evaluate tDCS effects on brain function

A checklist for assessing the methodological quality of concurrent tES-fMRI studies (ContES checklist): a consensus study and statement

Background: Low intensity transcranial electrical stimulation (tES), including alternating or direct current stimulation (tACS or tDCS), applies weak electrical stimulation to modulate the activity of brain circuits. Integration of tES with concurrent functional magnetic resonance imaging (fMRI) allows for the mapping of neural activity during neuromodulation, supporting causal studies of both brain function and tES effects. Methodological aspects of tES-fMRI studies underpin the results, and reporting them in appropriate detail is required for reproducibility and interpretability. Despite the growing number of published reports, there are no consensus-based checklists for disclosing methodological details of concurrent tES-fMRI studies. Objective: To develop a consensus-based checklist of reporting standards for concurrent tES-fMRI studies to support methodological rigor, transparency, and reproducibility (ContES Checklist). Methods: A two-phase Delphi consensus process was conducted by a steering committee (SC) of 13 members and 49 expert panelists (EP) through the International Network of the tES-fMRI (INTF) Consortium. The process began with a circulation of a preliminary checklist of essential items and additional recommendations, developed by the SC based on a systematic review of 57 concurrent tES-fMRI studies. Contributors were then invited to suggest revisions or additions to the initial checklist. After the revision phase, contributors rated the importance of the 17 essential items and 42 additional recommendations in the final checklist. The state of methodological transparency within the 57 reviewed concurrent tES-fMRI studies was then assessed using the checklist. Results: Experts refined the checklist through the revision and rating phases, leading to a checklist with three categories of essential items and additional recommendations: (1) technological factors, (2) safety and noise tests, and (3) methodological factors. The level of reporting of checklist items varied among the 57 concurrent tES-fMRI papers, ranging from 24% to 76%. On average, 53% of checklist items were reported in a given article. Conclusions: Use of the ContES checklist is expected to enhance the methodological reporting quality of future concurrent tES-fMRI studies, and increase methodological transparency and reproducibility
