Intrinsically Decoupled Coordination Chemistries Enable Quasi-Eutectic Electrolytes with Fast Kinetics toward Enhanced Zinc-Ion Capacitors.

Eutectic electrolytes show potential beyond conventional low-concentration electrolytes (LCEs) in zinc (Zn)-ion capacitors (ZICs) yet suffer from high viscosity and sluggish kinetics. Herein, we originally propose a universal theory of intrinsically decoupling to address these issues, producing a novel electrolyte termed "quasi-eutectic" electrolyte (quasi-EE). Joint experimental and theoretical analyses confirm its unique solution coordination structure doped with near-LCE domains. This enables the quasi-EE well inherit the advanced properties at deep-eutectic states while provide facilitated kinetics as well as lower energy barriers via a vehicle/hopping-hybridized charge transfer mechanism. Consequently, a homogeneous electroplating pattern with much enhanced Sand's time is achieved on the Zn surface, followed by a twofold prolonged service-life with drastically reduced concentration polarization. More encouragingly, the quasi-EE also delivers increased capacitance output in ZICs, which is elevated by 12.4 %-144.6 % compared to that before decoupling. Furthermore, the pouch cell with a cathodic mass loading of 36.6 mg cm-2 maintains competitive cycling performances over 600 cycles, far exceeding other Zn-based counterparts. This work offers fresh insights into eutectic decoupling and beyond.

Scoring molecular wires subject to an ultrafast laser pulse for molecular electronic devices.

A nonionizing ultrafast laser pulse of 20-fs duration with a peak amplitude electric-field ±E = 200 × 10-4 a.u. was simulated. It was applied to the ethene molecule to consider its effect on the electron dynamics, both during the application of the laser pulse and for up to 100 fs after the pulse was switched off. Four laser pulse frequencies ω = 0.2692, 0.2808, 0.2830, and 0.2900 a.u. were chosen to correspond to excitation energies mid-way between the (S1 ,S2 ), (S2 ,S3 ), (S3 ,S4 ) and (S4 ,S5 ) electronic states, respectively. Scalar quantum theory of atoms in molecules (QTAIM) was used to quantify the shifts of the C1C2 bond critical points (BCPs). Depending on the frequencies ω selected, the C1C2 BCP shifts were up to 5.8 times higher after the pulse was switched off compared with a static E-field with the same magnitude. Next generation QTAIM (NG-QTAIM) was used to visualize and quantify the directional chemical character. In particular, polarization effects and bond strengths, in the form of bond-rigidity vs. bond-flexibility, were found, for some laser pulse frequencies, to increase after the laser pulse was switched off. Our analysis demonstrates that NG-QTAIM, in partnership with ultrafast laser irradiation, is useful as a tool in the emerging field of ultrafast electron dynamics, which will be essential for the design, and control of molecular electronic devices.

Psychological distress in pregnancy and postpartum: a cross-sectional study of Babol pregnancy mental health registry.

BACKGROUND: Psychological distress (PD) is a significant issue during pregnancy and postpartum, adversely affecting both children and mothers. This study aims to determine PD's prevalence and risk factors in a large Iranian population sample during pregnancy and postpartum. METHODS: A cross-sectional study was conducted using data from the Babol Pregnancy Mental Health Registry (located in the north of Iran) between June 2020 and March 2021. A total of 2305 women were included, with 1639 during pregnancy and 666 during postpartum. Psychological distress was assessed using the Brief Symptoms Inventory (BSI-18), and data were analyzed using independent t-tests and multiple logistic regressions. RESULTS: The prevalence of psychological distress, defined by a cut-off score of BSI ≥ 13, was 19% during pregnancy and 15% during postpartum. Multivariate logistic analysis revealed that high-risk pregnancy was the leading risk factor for psychological distress during the antenatal period (ß = 1.776, P < 0.001), as well as its three subscales: somatization (ß = 1.355, P = 0.019), anxiety symptoms (ß = 2.249, P < 0.001), and depressive symptoms (ß = 1.381, P = 0.028). Additionally, women with a gestational age < 20 weeks had a higher risk of psychological distress (ß = 1.344, P = 0.038) and the somatization subscale (ß = 1.641, P < 0.001). During the postpartum period, women residing in urban areas were at higher risk of psychological distress (ß = 1.949, P = 0.012), as well as two subscales: anxiety symptoms (ß = 1.998, P = 0.012) and depressive symptoms (ß = 1.949, P = 0.020). CONCLUSION: The high prevalence of psychological distress emphasizes detecting and treating PD during pregnancy and postpartum, particularly in women with high-risk pregnancies. This study suggests that obstetricians and midwives should implement programs to identify women experiencing psychological distress during early pregnancy through postpartum visits.

The impact of health coaching on the prevention of gestational diabetes in overweight/obese pregnant women: a quasi-experimental study.

BACKGROUND: Previous studies have demonstrated that excessive gestational weight gain (GWG) increases the risk of gestational diabetes mellitus (GDM). This study aimed to determine the effect of using health coaching on the prevention of GDM in overweight pregnant women. METHODS: In this quasi-experimental study, 64 eligible overweight women at 12-14 gestational weeks were randomly divided into 2 groups: the coaching group and the control group (usual care group). The intervention group received 8 weeks of the phone coaching program, which integrated GWG and physical activity to reduce the incidence of GDM. The Pregnancy Physical Activity Questionnaire (PPAQ) was used to assess physical activity during pregnancy. The occurrence of gestational diabetes was determined based on the 75-g 2-hour oral glucose tolerance test (OGTT) at 24-28 weeks of gestation. The primary outcome was the incidence of GDM, and the secondary outcomes included physical activity, GWG, and neonatal and maternal birth outcomes. RESULTS: The incidence of GDM in the control and intervention groups was 24.1% and 22.6%, respectively. The relative risk (RR) was 0.93 (95% CI, 0.37-2.34; P = 0.887). The post survey results indicated that GWG decreased more considerably in the coaching than in the control group between pre-trial (T0) and post-trial (T1), (MD; -2.49 with 95% CI, -4.38 to -0.60; P < 0.011). Moreover, the total GWG (between pre-pregnancy and birth) diminished more remarkably in the coaching than in the control group, (MD; -2.83 with 95% CI, -5.08 to -0.58; P < 0.014). However, the score of self-efficacy and concern about PPAQ Metabolic Equivalent of Task (METs) did not differ between the coaching and control groups. CONCLUSIONS: The findings and implications of this research could significantly contribute to maternal health and gestational diabetes prevention. Additional support from a midwife coach resulted in better GWG. More studies are needed to assess the impact of health coaching as a component of usual care and its long-term effect on maternal and neonatal outcomes.

Effect of psychosocial interventions on risky driving behaviours among offender drivers by using simulated and real driving: study protocol for a non-randomised controlled trial.

BACKGROUND: Risky driving behaviour including anger while driving has led to millions of global road traffic crashes, thousands of mortalities and injuries. These losses are much more in middle-income countries, such as Iran. This paper explains methods of data collection in a controlled trial study for evaluating the effect of psychosocial interventions on risky driving by using simulated and real driving. METHODS: This non-randomised controlled trial study will include 180 offender drivers. They will refer to the simulation laboratory by traffic police after their driving licences were suspended. At baseline, all participants will fill five questionnaires including demographic, Driving Anger Scale, Driving Anger Expression Scale, Spielberger's Anger and Manchester Driving Behavioural, and then they will be tested with a driving simulator. Afterwards, they will be allocated to one of three-intervention training arms (mindfulness, meta-cognition and social marketing) or a control arm without any training. Risky driving behaviours will be assessed in three follow-ups after intervention. The primary outcome of interest will be driving offences, recorded by traffic police in two time points: at 6 months and 1 year after the intervention. DISCUSSION: This study examines the effect of three interventions in reducing driving offence. The results can end in a new therapeutic training or a new legislation that should be added to current obligatory training for getting driving licence and can lead to long-term safe driving among Iranian drivers. Future research is recommended to study the cost-effectiveness of these interventions in actual driving in Iran. TRIAL REGISTRATION NUMBER: UMIN000039493.

New insights of QTAIM and stress tensor to finding non-competitive/competitive torquoselectivity of cyclobutene.

This study aims to investigate the phenomenon of torquoselectivity through three thermal cyclobutene ring-opening reactions (N1-N3). This research focuses on the nature of the chemical bond, electronic reorganization, predicting non-competitive or competitive reactions, and torquoselectivity preference within Quantum Theory of Atoms in Molecules (QTAIM) and stress tensor frameworks. Various theoretical analyses for these reactions, such as metallicity ξ(rb), ellipticity ε, total local energy density H(rb), stress tensor polarizability ℙσ, stress tensor eigenvalue λ3σ, and bond-path length, display differently for non-competitive and competitive reactions as well as for the conrotatory preferences either it is the transition state outward conrotatory (TSout) or transition state inward conrotatory (TSin) directions by presenting degeneracy or non-degeneracy in their results. The ellipticity profile provides the motion of the bond critical point locations due to the different substituents of cyclobutene. In agreement with experimental results, examinations demonstrated that N1 is a competitive reaction and N2-N3 are non-competitive reactions with TSout and TSin preference directions, respectively. The concordant results of QTAIM and stress tensor scalar and vectors with experimental results provide a better understanding of reaction mechanisms.

Next-generation QTAIM for scoring molecular wires in E-fields for molecular electronic devices.

The effect of a varying, directional E x , E y , and E z electric field on the ethene molecule was investigated using next-generation quantum theory of atoms in molecules (QTAIM). Despite using low E-field strengths that are within the realm of experiment and do not measurably alter the molecular geometry, significant changes to the QTAIM properties were observed. Using conventional QTAIM, the shifting of the C─C and C─H bond critical points (BCPs) demonstrates polarization through an interchange in the size of the atoms involved in a bond, since a BCP is located on the boundary between a pair of bonded atoms. Next-generation QTAIM, however, demonstrates the polarization effect more directly with a change in morphology of the 3-D envelope around the BCP. Modest increases of ≈ 2% in the ellipticity ε of the BCP were uncovered when the C─C bond was aligned parallel or anti-parallel to the applied E x -field. Significant asymmetries were found in the response of the next-generation QTAIM 3-D paths of the C─H bonds to the applied E-field. When the E-field coincided with the C─C bond, the BCP moved in response and was accompanied by the envelope constructed from 3-D next-generation paths. The response displayed a polarization effect that increased with increasing magnitude of the E x -field parallel and anti-parallel to the C─C bond. Our analysis demonstrates that next-generation QTAIM is a useful tool for understanding the response of molecules to E-fields, for example, for the screening of molecular wires for the design of molecular electronic devices. © 2019 Wiley Periodicals, Inc.

3-D bond-paths of QTAIM and the stress tensor in neutral lithium clusters, Lim (m = 2-5), presented on the Ehrenfest force molecular graph.

In this investigation we set out to understand the origins of non-nuclear attractors (NNAs) found for neutral lithium clusters Lim (m = 2-5) on the QTAIM molecular graph but not on the Ehrenfest force F(r) molecular graph. Therefore, we pursued the stress tensor σ(r) without using the dependency on the QTAIM partitioning, since previously σ(r) was only calculated within the QTAIM partitioning, to see if any indication of NNA character can be determined. Because the stress tensor σ(r) lacks an associated scalar- or vector-field as is the case for QTAIM and the Ehrenfest F(r) partitioning schemes respectively, a stress tensor σ(r) partitioning scheme cannot be constructed. Therefore, to overcome this difficulty we use next generation QTAIM, constructed from the most preferred directions of electronic charge density accumulation, to calculate the stress tensor σ(r) 3-D bond-paths on the Ehrenfest force F(r) molecular graph. Using next generation 3-D bond-paths within the Ehrenfest force F(r) partitioning, we can classify the degree of NNA character in the absence of NNAs. A much higher degree of NNA character is found to be present for the stress tensor σ(r) 3-D bond-paths than for the corresponding QTAIM or Ehrenfest force F(r) 3-D bond-paths. The stabilizing effect of the NNA is demonstrated by undertaking Li2 bond-path compression and stretching distortions sufficient to cause the annihilation of the NNA. The compression and stretching distortions also lead to a large increase in the 3-D bond-path asymmetry and persistent bond-path torsion respectively.

Absence of AfuXpot, the yeast Los1 homologue, limits Aspergillus fumigatus growth under amino acid deprived condition.

In Saccharomyces cerevisiae, los1 encodes a nuclear tRNA exporter. Despite the non-essentiality, the deletion of los1 has been shown to extend replicative life span in yeast. Here, we characterized AfuXpot, the los1 homologue in human pathogen Aspergillus fumigatus and found that it is continuously expressed during fungal growth. Microscopic examination of an AfuXpot-GFP-expressing transformant confirmed the nuclear localization of the fusion protein. The targeted gene deletion affirmed the non-essential role of AfuXpot in hyphal growth and sporulation. However, the growth of the deletion mutant was affected by amino acid, but not glucose, deprivation. The susceptibility of the deletant strain to protein and DNA/RNA synthesis inhibitors was also altered. Using bioinformatics tools, some transcription factor binding sites were predicted in AfuXpot promoter. Expression analyses of potential AfuXpot-interacting genes showed a marked down-regulation of sfp1 and mtr10 homologues in ΔAfuXpot strain. Our data demonstrates some conserved aspects of AfuXpot as a tRNA exporter in A. fumigatus.

The destabilization of hydrogen bonds in an external E-field for improved switch performance.

The effect of an electric field on a recently proposed molecular switch based on a quinone analogue was investigated using next-generation quantum theory of atoms in molecules (QTAIM) methodology. The reversal of a homogenous external electric field was demonstrated to improve the "OFF" functioning of the switch. This was achieved by destabilization of the H atom participating in the tautomerization process along the hydrogen bond that defines the switch. The "ON" functioning of the switch, from the position of the tautomerization barrier, is also improved by the reversal of the homogenous external electric field: this result was previously inaccessible. The "ON" and "OFF" functioning of the switch was visualized in terms of the response of the most preferred directions of motion of the electronic charge density to the applied external field. All measures from QTAIM and the stress tensor provide consistent results for the factors affecting the "ON" and "OFF" switch performance. Our analysis therefore demonstrates use for future design of molecular electronic devices. © 2019 Wiley Periodicals, Inc.

Stress Tensor Eigenvector Following with Next-Generation Quantum Theory of Atoms in Molecules: Excited State Photochemical Reaction Path from Benzene to Benzvalene.

In this investigation, we considered both the scalar and 3-D vector-based measures of bonding using next generation quantum theory of atoms in molecules (QTAIM), constructed from the preferred direction of electronic charge density accumulation, to better understand the photochemical reaction associated with of the formation of benzvalene from benzene. The formation of benzvalene from benzene resulted in two additional C-C bonds forming compared with the benzene. The creation of the additional C-C bonds was explained in terms of an increasing the favorability of the reaction process by maximizing the bonding density. The topological instability of the benzvalene structure was determined using the scalar and vector-based measures to explain the short chemical half-life of benzvalene in terms of the competition between the formation of unstable new C-C bonding that also destabilizes nearest neighbor C-C bonds. The explosive character of benzvalene is indicated by the unusual tendency of the C-C bonds to rupture as easily as weak bonding. The topological instability of the short strong C-C bonds was explained by the existence of measures from conventional and next generation QTAIM that previously have only been observed in weak interactions; such measures included twisted 3-D bonding descriptors.

Non-nuclear attractors in small charged lithium clusters, Limq (m = 2-5, q = ±1), with QTAIM and the Ehrenfest force partitioning.

In this investigation we explore the function and existence of the non-nuclear attractor (NNA) for a series of small charged lithium clusters Limq (m = 2-5, q = ±1) using QTAIM and the Ehrenfest force F(r) partitioning schemes. The NNAs were found to be present in all of the Limq (m = 2-5, q = ±1) clusters for QTAIM, in contrast none were found for F(r). We discovered that the anionic and cationic lithium dimers are limiting cases for minimal and maximal impact of the NNA related to the relative sparseness of total charge density ρ(r) distributions respectively. Evidence is found that the NNA in the anionic dimer is in the process of being annihilated by two neighboring BCPs. We provide a measure of the size of the NNA and find for Limq (m = 2-5, q = ±1) that larger NNAs correlate with increased Li-Li separations. The NNA was determined to be a persistent feature by varying the Li separations for the cationic and anionic dimers. Very large Li separations failed to induce an NNA in the F(r) anionic dimer and therefore we conclude that F(r) is unable to detect NNAs. The metallicity ξ(rb) was also used to measure the sparseness of the distribution of ρ(r) and significant metallic character, on the basis of ξ(rb) > 1, was present for QTAIM but not for F(r), providing further evidence that F(r) cannot detect NNAs. Advantages of the use of Ehrenfest force F(r) partitioning scheme are discussed that include the design of nano-devices through tuning of the Ehrenfest potential VF(b) by the application of external forces such as a constant electric or strain field.

Exploration of the forbidden regions of the Ramachandran plot (ϕ-ψ) with QTAIM.

A new QTAIM interpretation of the Ramachandran plot is formulated from the most and least facile eigenvectors of the second-derivative matrix of the electron density with a set of 29 magainin-2 peptide conformers. The presence of QTAIM eigenvectors associated with the most and least preferred directions of electronic charge density explained the role of hydrogen bonding, HH contacts and the glycine amino acid monomer in peptide folding. The highest degree of occupation of the QTAIM interpreted Ramachandran plot was found for the glycine amino acid monomer compared with the remaining backbone peptide bonds. The mobility of the QTAIM eigenvectors of the glycine amino acid monomer was higher than for the other amino acids and was comparable to that of the hydrogen bonding, explaining the flexibility of the magainin-2 backbone. We experimented with a variety of hybrid QTAIM-Ramachandran plots to highlight and explain why the glycine amino acid monomer largely occupies the 'forbidden' region on the Ramachandran plot. In addition, the new hybrid QTAIM-Ramachandran plots contained recognizable regions that can be associated with concepts familiar from the conventional Ramachandran plot whilst retaining the character of the QTAIM most and least preferred regions.

QTAIM and Stress Tensor Characterization of Intramolecular Interactions Along Dynamics Trajectories of a Light-Driven Rotary Molecular Motor.

A quantum theory of atoms in molecules (QTAIM) and stress tensor analysis was applied to analyze intramolecular interactions influencing the photoisomerization dynamics of a light-driven rotary molecular motor. For selected nonadiabatic molecular dynamics trajectories characterized by markedly different S1 state lifetimes, the electron densities were obtained using the ensemble density functional theory method. The analysis revealed that torsional motion of the molecular motor blades from the Franck-Condon point to the S1 energy minimum and the S1/S0 conical intersection is controlled by two factors: greater numbers of intramolecular bonds before the hop-time and unusually strongly coupled bonds between the atoms of the rotor and the stator blades. This results in the effective stalling of the progress along the torsional path for an extended period of time. This finding suggests a possibility of chemical tuning of the speed of photoisomerization of molecular motors and related molecular switches by reshaping their molecular backbones to decrease or increase the degree of coupling and numbers of intramolecular bond critical points as revealed by the QTAIM/stress tensor analysis of the electron density. Additionally, the stress tensor scalar and vector analysis was found to provide new methods to follow the trajectories, and from this, new insight was gained into the behavior of the S1 state in the vicinity of the conical intersection.

Smartphone addiction in Iranian schoolchildren: a population-based study.

Smartphone addiction is a public health problem and is increasing globally. It is important to know the latest status of this phenomenon in different region of the world. This study aimed to investigate smartphone addiction in an Iranian student population. The participants were a random sample of Shahroud Schoolchildren Eye Cohort study in 2018. Smartphone addiction was measured by the Smartphone Addiction Scale Short Version (SAS-sv) questionnaire. The prevalence and mean estimates were reported with 95% confidence intervals. The analysis of variance, t-test and multiple logistic regression were used for analysis of data. The mean age of 2682 participating students was 13.5 year with an age range of 10 to 15 year, and 1197 (44.6%) of them were girls. The mean SAS-sv score was 27.96 (95% CI: 27.36-28.58) for boys and 26.10 (95% CI: 25.34-26.80) for girls. This score follows a U-shaped pattern with a lower mean score observed at age 8. The Prevalence of smartphone addiction was 29.8% (95% CI: 28.1-31.5) in studied population. Compared to 10 year old students, smartphone addiction was higher in 14 (Odds Ratio (OR) = 1.7, 95% CI: 1.1-2.7) and 15 (OR = 2.4, 95% CI: 1.5-3.8) years old students. Smartphone addiction was higher in boys (OR = 1.9; 95% CI, 1.5-3.0; P value < 0.001). Smartphone addiction was not different in urban and rural students after adjusting for age and gender (P = 0.089). Compared to European countries the prevalence of smartphone addiction in Iranian students is relatively high and need prompt intervention especially in boys and older adolescents.

Body image concern and demographic characteristics as predictors of anxiety in adolescent girls.

OBJECTIVES: Adolescence is a critical and sensitive period of growth, marked by significant physical and psychological changes. During this time, adolescents often experience increased anxiety and concerns about their body image. This study aims to examine body image concern and demographic characteristics as predictors of anxiety in adolescent girls. METHODS: This cross-sectional study included 381 female students aged 12-13 from Babol city. The participants were selected based on predefined inclusion criteria. Multi-stage sampling method was employed, and the samples were selected from six middle schools. The data collection tools consisted of a demographic information questionnaire, Littleton's body image concern scale, and Zung's anxiety scale. RESULTS: The mean score for body image concern was 16.59±44.82, while the mean score for anxiety was 10.53±37.31. When investigating the relationship between body image concern and anxiety, a significant and positive correlation between these two variables was observed during regression analysis (p<0.001). Both univariate and multivariate regression analyses indicated that for every one-unit increase in students' body image concern score, their overall anxiety score increased by an average of 0.34 units in both models (B: 0.34, 95 % CI: 0.29-0.39) (p<0.001). Additionally, in univariate regression analyses students who received puberty information from sources other than their mother exhibited 2.68 units higher anxiety levels, which was statistically significant (B: 2.68, 95 % CI: 0.38-4.98) (p<0.001) and, concerning the preferred source of information, students who favored a non-mother source experienced 3.91 units increase in their anxiety score (B: 3.91, 95 % CI: 1.74-6.08) (p<0.001). The results of multivariate regression analysis showed that with the presence of all independent variables in the model, 30 % of the dependent variable changes can be predicted (explained) (R 2 =0.302). CONCLUSIONS: The findings indicated a positive association between body image concerns and anxiety among students. Moreover, students who relied on sources other than their mother for obtaining information about puberty displayed higher levels of anxiety. Consequently, it is imperative to implement preventive and supportive programs targeting adolescents as well as empowering mothers to effectively deal with these issues.

The effectiveness of pubertal health group counseling based on problem-solving, on body image concerns and anxiety in adolescent girls: Study protocol.

BACKGROUND: Body image concerns are accepted as a pervasive problem by a large segment of society. Problem-solving counseling is one of the practical counseling techniques that mainly focuses on improving people's adaptability in stressful situations. We intend to determine the effectiveness of pubertal health group counseling based on problem-solving on body image concerns and anxiety in adolescent girls. MATERIALS AND METHODS: A semi-experimental study will be conducted on 12-13 years old students in Babol (Mazandaran, Iran). One hundred people were determined as the final Sample size (50 people in each group) and will be selected to enter the study. A multistage sampling method will be used. The students of the intervention group will receive the necessary training in the problem-solving method regarding pubertal health, once a week for six weeks. Students in the control group will not receive education during the intervention period. Sociodemographic questionnaire, Littleton's body image concern, and Zong's anxiety will be used to evaluate students' body image concerns and anxiety. Analyzes will be done by statistical package for the social sciences (SPSS) version 25 software and a significance level of 5% will be considered. Descriptive statistics and frequency percentage will be determined for classification variables. Median, range, and mean along with standard deviations (SD) will be calculated. The Chi-square test, Repeated Measures ANOVA and ANCOVA test will be used in this study. Percentage prevalence for each categorical variable is calculated with 95% confidence interval (CI). DISCUSSION: The effectiveness of counseling based on problem-solving has been reported in various studies on adolescent puberty health concerns and common adolescent mental health problems, hence its application on girls' body image can be effective.

The Impact of Mindfulness-Based Counseling on the Mental Health of Women With a History of COVID-19 During Pregnancy: A Quasi-Experimental Study.

INTRODUCTION: With the spread of COVID-19, certain population groups, including pregnant women, were more susceptible than others. This disease can lead to postpartum complications, including mental disorders, in mothers. Few studies have investigated the impact of mindfulness-based interventions on mental health, and the most effective counseling approach to promote mental health has not been identified. OBJECTIVE: This study aimed to determine the impact of online mindfulness-based counseling on improving mental health among women with a history of COVID-19 during pregnancy in Iran. METHODS: The present study was a quasi-experimental design conducted on 100 women with a history of coronavirus infection during pregnancy referred to the Mother's Clinic of Yahya Nejad and Ayatollah Rouhani Educational-Treatment Hospital, affiliated with Babol University of Medical Sciences, Iran, via convenience sampling. The women were randomly assigned to the intervention (mindfulness-based counseling) and control groups. The intervention group received eight 45-min weekly mindfulness-based counseling sessions over 8 weeks. Data were collected via a demographic information questionnaire and the Goldberg General Health Questionnaire before and after the intervention, which were completed by both groups. Independent t-tests and analysis of covariances (ANCOVAs) were used to compare the outcomes of the two groups. RESULTS: After controlling for confounding variables, the mean mental health scores before and after counseling were 29.42 ± 4.49 and 19.80 ± 3.88, respectively, in the intervention group and 26.26 ± 2.29 and 25.92 ± 2.15, respectively, in the control group. The mean mental health score in the intervention group was significantly lower than that in the control group (F = 266.7, p < 0.001). The mean scores for somatic symptoms (F = 89.30, p < 0.001), depression symptoms (F = 142.71, p < 0.001), anxiety and insomnia symptoms (F = 120.56, p < 0.001), and social dysfunction scores (F = 127.77, p < 0.001) were significantly different between the two groups after counseling. CONCLUSION: The findings indicated that online mindfulness-based counseling positively affects mental health and its domains during the postpartum period. However, further randomized clinical trials are needed before a definitive conclusion can be drawn. TRIAL REGISTRATION: We were not allowed to register according to the law of our country.

Unleashing the high energy potential of zinc-iodide batteries: high-loaded thick electrodes designed with zinc iodide as the cathode.

The realization of high energy is of great importance to unlock the practical potential of zinc-iodine batteries. However, significant challenges, such as low iodine loading (mostly less than 50 wt%), restricted iodine reutilization, and severe structural pulverization during cycling, compromise its intrinsic features. This study introduces an optimized, fully zincified zinc iodide loaded onto a hierarchical carbon scaffold with high active component loading and content (82 wt%) to prepare a thick cathode for enabling high-energy Zn-I2 batteries. The synergistic interactions between nitrogen heteroatoms and cobalt nanocrystals within the porous matrix not only provide forceful chemisorption to lock polyiodide intermediates but also invoke the electrocatalytic effects to manipulate efficient iodine conversion. The ZnI2 cathode could effectively alleviate continuous volumetric expansion and maximize the utilization of active species. The electrochemical examinations confirm the thickness-independent battery performance of assembled Zn-I2 cells due to the ensemble effect of composite electrodes. Accordingly, with a thickness of 300 µm and ZnI2 loading of up to 20.5 mg cm-2, the cathode delivers a specific capacity of 92 mA h gcathode-1 after 2000 cycles at 1C. Moreover, the Zn-I2 pouch cell with ZnI2 cathode has an energy density of 145 W h kgcathode-1 as well as a stable long cycle life.

Prevalence and Risk Factors of Prenatal and Postnatal Depressive Symptoms in Babol Pregnancy Mental Health Registry: A Cross-Sectional Study.

BACKGROUND: Prenatal and postnatal depression (PND) is associated with adverse outcomes for mother, fetus, and child. The aim of study was to examine the prevalence and risk factors of prenatal and postnatal depressive symptoms. MATERIALS AND METHODS: This was a cross-sectional and hospital-based survey of 2305 pregnant women and post-partum women (18-48 years) that was registered in the Babol Pregnancy Mental Health Registry (BPMHR) database from June 2020 to March 2021. Two questionnaires, including demographics and depression, were analyzed in this study. Also, the Edinburg Postnatal Depression Scale (EPDS) was used to assess the depressive symptoms. Independent t test and the analysis of variance were used to compare the means. Multiple logistic regressions were used to determine risk factors for depressive symptoms. RESULTS: According to the EPDS scale, the prevalence of depressive symptoms was 19.8% in the pregnant woman group in comparison with the postpartum period (11.6%). Risk factors for antenatal depressive symptoms were parity (women with parity ≥ 4 vs. 1 parity, ß=1.808, P=0.020), two groups of gestational age (gestational age ≤12 weeks vs. 28 weeks, ß=1.562 P=0.030) as well as (gestational age 21-27 weeks vs. 28 weeks (ß=1.586, P=0.033), and high-risk pregnancy (high-risk vs. low-risk pregnancy, ß=1.457, P=0.003). For postnatal depressive symptoms, none of the factors were a significant risk. CONCLUSION: Prenatal and postnatal depressive symptoms should be screened, particularly for women in the first and second trimesters, with high parity, and those with a high-risk pregnancy, as recommended by the present study.
