Generic dynamic molecular devices by quantitative non-steady-state proton/water-coupled electron transport kinetics.

Dynamic molecular devices operating with time- and history-dependent performance raised new challenges for the fundamental study of microscopic non-steady-state charge transport as well as functionalities that are not achievable by steady-state devices. In this study, we reported a generic dynamic mode of molecular devices by addressing the transient redox state of ubiquitous quinone molecules in the junction by proton/water transfer. The diffusion limited slow proton/water transfer-modulated fast electron transport, leading to a non-steady-state transport process, as manifested by the negative differential resistance, dynamic hysteresis, and memory-like behavior. A quantitative paradigm for the study of the non-steady-state charge transport kinetics was further developed by combining the theoretical model and transient state characterization, and the principle of the dynamic device can be revealed by the numerical simulator. On applying pulse stimulation, the dynamic device emulated the neuron synaptic response with frequency-dependent depression and facilitation, implying a great potential for future nonlinear and brain-inspired devices.

Exploring Pyrazine-Based Organic Redox Couples for Enhanced Thermoelectric Performance in Wearable Energy Harvesters.

Thermoelectric generators (TEGs) based on thermogalvanic cells can convert low-temperature waste heat into electricity. Organic redox couples are well-suited for wearable devices due to their nontoxicity and the potential to enhance the ionic Seebeck coefficient through functional-group modifications.  Pyrazine-based organic redox couples with different functional groups is comparatively analyzed through cyclic voltammetry under varying temperatures. The results reveal substantial differences in entropy changes with temperature and highlight 2,5-pyrazinedicarboxylic acid dihydrate (PDCA) as the optimal candidate. How the functional groups of the pyrazine compounds impact the ionic Seebeck coefficient is examined, by calculating the electrostatic potential based on density functional theory. To evaluate the thermoelectric properties, PDCA is integrated in different concentrations into a double-network hydrogel comprising poly(vinyl alcohol) and polyacrylamide. The resulting champion device exhibits an impressive ionic Seebeck coefficient (Si) of 2.99 mV K-1, with ionic and thermal conductivities of ≈67.6 µS cm-1 and ≈0.49 W m-1 K-1, respectively. Finally, a TEG is constructed by connecting 36 pieces of 20 × 10-3 m PDCA-soaked hydrogel in series. It achieves a maximum power output of ≈0.28 µW under a temperature gradient of 28.3 °C and can power a small light-emitting diode. These findings highlight the significant potential of TEGs for wearable devices.

Cu-N Synergism Regulation to Enhance Anionic Redox Reversibility and Activity of Li- and Mn-Rich Layered Oxides Cathode.

Anionic redox chemistry enables extraordinary capacity for Li- and Mn-rich layered oxides (LMROs) cathodes. Unfortunately, irreversible surface oxygen evolution evokes the pernicious phase transition, structural deterioration, and severe electrode-electrolyte interface side reaction with element dissolution, resulting in fast capacity and voltage fading of LMROs during cycling and hindering its commercialization. Herein, a redox couple strategy is proposed by utilizing copper phthalocyanine (CuPc) to address the irreversibility of anionic redox. The Cu-N synergistic effect of CuPc could not only inhibit surface oxygen evolution by reducing the peroxide ion O2 2- back to lattice oxygen O2-, but also enhance the reaction activity and reversibility of anionic redox in bulk to achieve a higher capacity and cycling stability. Moreover, the CuPc strategy suppresses the interface side reaction and induces the forming of a uniform and robust LiF-rich cathode electrolyte, interphase (CEI) to significantly eliminate transition metal dissolution. As a result, the CuPc-enhanced LMRO cathode shows superb cycling performance with a capacity retention of 95.0% after 500 long-term cycles. This study sheds light on the great effect of N-based redox couple to regulate anionic redox behavior and promote the development of high energy density and high stability LMROs cathode.

Chloroplast thiol redox dynamics through the lens of genetically encoded biosensors.

Chloroplasts fix carbon by using light energy and have evolved a complex redox network that supports plastid functions by (i) protecting against reactive oxygen species and (ii) metabolic regulation in response to environmental conditions. In thioredoxin- and glutathione/glutaredoxin-dependent redox cascades, protein cysteinyl redox steady states are set by varying oxidation and reduction rates. The specificity and interplay of these different redox-active proteins are still under investigation, for example to understand how plants cope with adverse environmental conditions by acclimation. Genetically encoded biosensors with distinct specificity can be targeted to subcellular compartments such as the chloroplast stroma, enabling in vivo real-time measurements of physiological parameters at different scales. These data have provided unique insights into dynamic behaviours of physiological parameters and redox-responsive proteins at several levels of the known redox cascades. This review summarizes current applications of different biosensor types as well as the dynamics of distinct protein cysteinyl redox steady states, with an emphasis on light responses.

Specific antibody responses to Qß-displayed Plasmodium falciparum-derived UB05 and MSP3 proteins in mother-neonate couples.

Malaria blood-stage parasite is a critical pathogenic stage responsible for serious adverse outcomes in pregnant women and their neonates. Immunoglobulin G (IgG) antibody responses specific to various asexual blood-stage antigens were well reported in non-pregnant individuals. However, little is still known during placental malaria. To assess the antibody responses specific to Plasmodium falciparum-derived MSP3 and UB05 malaria vaccine candidates in mother-neonate couples, mother's peripheral blood and neonate's cord blood samples were collected at delivery. After malaria diagnostic, plasma levels of IgG and IgG subclass responses specific to UB05, MSP3 and UB05-MSP3 were determined using ELISA. As outcomes, both mothers and neonates had significantly higher IgG responses to UB05 and UB05-MSP3 compared to anti-MSP3 IgG (p < 0.05), irrespective of malaria status. Significant negative correlations were observed between IgG levels specific to the three antigens and parasitaemia (p < 0.01). Anti-UB05 and anti-UB05-MSP3 IgG levels in neonates showed a significant positive correlation with the corresponding mothers' antibodies (rs = 0.25 with p = 0.04; rs = 0.31 with p = 0.01, respectively). UB05MSP3-specific IgG3 and IgG1 subclass responses were significantly higher than the IgG4 subclass (p < 0.01). The neonates IgG1 and IgG3 levels positively correlated with the corresponding antibody subclasses of mothers. These findings suggest an association between UB05 and UB05-MSP3-specific antibody responses and malaria control during pregnancy. Maternal-foetal transfer of MSP3 and UB05-specific IgG occurs during pregnancy, suggesting the interest in the future malaria vaccination strategies in pregnant women to generate early protective immunity in baby against malaria.

The effectiveness of couple-based interventions on the marital outcomes of women with genital and breast cancer and their partners: a systematic review and meta-analysis.

BACKGROUND: Breast cancer and genital cancer are known as cancers that affect people's relationships with their partners. Women with such cancers are emotionally vulnerable and need more support from their partners. The present systematic review and meta-analysis evaluated the effectiveness of couple-based interventions on the marital outcomes of patients with these cancers and their intimate partners. METHODS: To perform this systematic review, Google Scholar and databases such as PubMed, Web of Science, Cochrane, Scopus, SID (Scientific Information Database), and Magiran were searched systematically. The reviewed studies included randomized controlled trials and quasiexperimental studies in which the intervention group, couple-based interventions, and the control group received routine care, general education or no intervention for cancer treatment. In this study, the included participants were patients with breast cancer or genital cancer and their intimate partners. The primary outcomes considered in this study included patients' marital adjustment, patients' marital satisfaction, patients' marital intimacy, and patients' marital relationships. The secondary outcomes were partners' marital adjustment, partners' marital satisfaction, partners' marital intimacy, and partners' marital relationships. A meta-analysis was performed with Review Manager v. 5.3 software (The Nordic Cochrane Centre, Cochrane Collaboration, 2014; Copenhagen, Denmark). The intervention impacts on continuous outcomes were measured using standardized mean differences (SMDs) with 95% confidence interval because of the use of various scales to evaluate the outcomes. The quality of evidence presented in the included studies was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. In the subgroup analysis, the studied outcomes were divided into two parts (theory-based and non-theory-based) in terms of the theoretical context of couple-based interventions. RESULTS: From a total of 138 retrieved studies, 14 trials were eligible for inclusion in the study. The results of the meta-analysis showed that the patient's marital satisfaction increased significantly with couple-based interventions (SMD 0.46, 95% confidence interval 0.07 to 0.85; 7 trials, 341 patients, very low certainty) compared to the control group, but the evidence was uncertain. However, there were no significant differences between the groups in the partner's marital satisfaction, the patient's and partner's marital adjustment, and the patient's and partner's marital intimacy. Additionally, the results of the subgroup analysis showed that the couple-based interventions significantly increased the patient's marital adjustment (SMD 1.96, 95% CI 0.87 to 3.06; 4 trials, 355 patients, very low certainty), the partner's marital adjustment (SMD 0.53, 95% CI 0.20 to 0.86; 4 trials, 347 partners, very low certainty), the patient's marital satisfaction (SMD 0.89, 95% CI 0.35 to 1.43; 2 trials, 123 patients, very low certainty), and the partner's marital satisfaction (SMD 0.57, 95% CI 0.20 to 0.94; 2 trials, 123 partners, very low certainty) compared to the control group in theory-based studies. In. However, in non-theory-based studies, the results of the meta-analysis revealed no significant differences between the intervention and control groups. CONCLUSIONS: The results of this study demonstrated the impact of couple-based interventions on the marital outcomes of patients with breast and genital cancers. Because of the very low confidence in the evidence, high-quality randomized trials with a sufficient sample size should be conducted considering the proper theoretical context.

Sexual counseling for female sexual interest/arousal disorders: a randomized controlled trial based on the "good enough sex" model.

BACKGROUND: Female sexual interest/arousal disorder (FSIAD) is the most common female sexual disorder with adverse effects on women's health and interpersonal relationships. AIM: This survey evaluated the effects of sexual counseling based on the "good enough sex" (GES) model on the sexual health variables of women with FSIAD. METHODS: A randomized clinical trial with a 1:1 allocation ratio was conducted among 80 women with FSIAD in Iran in 2021. Eligible participants were randomly assigned to group A (women) and group B (couples). Women attended 4 weekly online group sexual counseling sessions based on the GES model, each lasting 120 minutes. In group B, husbands participated in sessions 2 and 3. OUTCOMES: Women's sexual health parameters-including sexual desire, sexual satisfaction, sexual function, sexual distress, sexual communication, frequency of sexual intercourse, and dysfunctional beliefs-were evaluated before and 3 months after counseling. The significance threshold considered P < .007 due to Bonferroni correction. RESULTS: After the intervention, all sexual parameters except sexual dysfunctional beliefs showed significant improvement (P < .001) in both groups. During the follow-up period, the average scores for all sexual variables were slightly higher in group B vs group A. The between-group difference was significant only for frequency of sexual intercourse (P < .01). CLINICAL IMPLICATIONS: This study reaffirms the impact of the GES model as biopsychosocial therapy in managing female sexual problems. Considering men's reluctance to accompany their wives to sex clinics, counseling for women alone can play a significant role in solving sexual problems, especially in the case of FSIAD. Online sexual consultation offers cost and time savings, provides a secure space for discussing sensitive topics, and facilitates group program coordination. It ensures universal access to counseling, thereby addressing gender incompatibility issues. It is a powerful, interactive, and acceptable alternative to in-person visits, providing convenience and confidentiality for clients seeking sexual health support. STRENGTHS AND LIMITATIONS: The following were among the survey strengths: conducting a randomized controlled trial on women with FSIAD by applying an appropriate model and scales, involving spouses, and evaluating online group sexual counseling. However, the results of this study may not be generalizable to women without partners. CONCLUSION: The GES model, emphasizing intimacy and sexual dialogue, reduces unrealistic sexual expectations and improves women's sexual desire and overall health. Our results showed that instead of insisting on the physical presence of husbands in counseling sessions, clinicians should emphasize their emotional support and companionship during the treatment process.

The effect of a couple-based posttraumatic growth intervention in supporting couples coping with colorectal cancer: A randomized controlled study.

OBJECTIVES: To promote posttraumatic growth (PTG) in colorectal cancer (CRC) couples, a couple-based PTG intervention was conducted, and the intervention had previously proved be feasible in CRC couples. The current study was conducted to validate the effects of intervention in CRC couples. METHOD: This is a randomized controlled study that included 174 CRC couples. All participants were randomized to either the intervention (usual care plus 5-week PTG intervention, n = 87) or the control group (usual care, n = 87). Data were collected from CRC couple dyads at baseline and immediately post-intervention periods. Primary outcome refers to positive changes, and secondary outcomes include marital satisfaction, quality of life (QOL), and anxiety and depression. Multilevel modeling was applied to analyze the intervention effects. RESULTS: Participants in the program showed increased PTG, marital satisfaction, and QOL both physically and mentally, and decreased levels of anxiety and depression over time. And spousal caregivers showed greater improvement in marital satisfaction and physical QOL compared with patients. In addition, significant intervention effects were shown in the participants' benefit finding, physical health and depressive symptoms. CONCLUSION: The study confirmed the effect of the PTG intervention on CRC couples' benefit finding, physical health and depressive symptoms. However, this study only measured outcome variables at two time-points. Future studies should add follow-up assessments to evaluate long-term effects of the intervention in CRC couples. REGISTRATION NUMBER: ChiCTR2300067809.

Behavioral Modeling and its Association with PrEP and ART Use in Ugandan HIV-Serodifferent Couples.

Integrating Pre-Exposure Prophylaxis (PrEP) delivery into Antiretroviral Therapy (ART) programs bridges the Human Immunodeficiency Virus (HIV) prevention gap for HIV-serodifferent couples prior to the partner living with HIV achieving viral suppression. Behavioral modeling is one mechanism that could explain health-related behavior among couples, including those using antiretroviral medications, but few tools exist to measure the extent to which behavior is modeled. Using a longitudinal observational design nested within a cluster randomized trial, this study examined the factor structure and assessed the internal consistency of a novel 24-item, four-point Likert-type scale to measure behavioral modeling and the association of behavioral modeling with medication-taking behaviors among heterosexual, cis-gender HIV-serodifferent couples. In 149 couples enrolled for research, a five-factor model provided the best statistical and conceptual fit, including attention to partner behavior, collective action, role modeling, motivation, and relationship quality. Behavioral modeling was associated with medication-taking behaviors among members of serodifferent couples. Partner modeling of ART/PrEP taking could be an important target for assessment and intervention in HIV prevention programs for HIV serodifferent couples.

Healthcare Providers' Perspectives on a Novel Couple-Based HIV Treatment Intervention: A Qualitative Assessment of the Facilitators, Barriers, and Proposed Improvements to Implementation in Zambézia Province, Mozambique.

Mozambique has one of the world's highest HIV/AIDS burdens. Despite significant investment in HIV care and treatment, pregnant and lactating women's retention in care remains suboptimal. One reason for poor maternal retention is lack of male partner support. We tested an interventional couple-based HIV care and treatment, including joint clinical appointments and couple-based educational and support sessions provided by a health counselor and peer educators, respectively. Healthcare providers delivering care for seroconcordant individuals were interviewed regarding their perspectives on facilitators and barriers to the couple-based intervention implementation. Analysis of interview responses was done using MAXQDA. Results pertaining to providers' perspectives on implementation and intervention characteristics were organized, interpreted, and contextualized using the Consolidated Framework for Implementation Research (CFIR 2.0), while providers' suggestions for improvements were coded and organized apart from CFIR. Providers felt the intervention was largely compatible with the local culture, and offered a significant advantage over standard individual-based care by facilitating patient follow-up and reducing wait times by prioritizing couples for services. They also believed it facilitated HIV treatment access through the provision of couple-based counseling that encouraged supportive behaviors towards retention. However, providers reported insufficient privacy to deliver couple-based care at some health facilities and concerns that women in difficult relationships may struggle to meaningfully participate. They suggested providing sessions in alternate clinic settings and offering a limited number of women-only visits. The facilitators and barriers described here contribute to informing the design and implementation of future couple-based interventions to improve HIV care for seroconcordant expectant couples.

Predictors of Serum Per- and Polyfluoroalkyl Substances Concentrations among U.S. Couples Attending a Fertility Clinic.

Previous studies have examined the predictors of PFAS concentrations among pregnant women and children. However, no study has explored the predictors of preconception PFAS concentrations among couples in the United States. This study included 572 females and 279 males (249 couples) who attended a U.S. fertility clinic between 2005 and 2019. Questionnaire information on demographics, reproductive history, and lifestyles and serum samples quantified for PFAS concentrations were collected at study enrollment. We examined the PFAS distribution and correlation within couples. We used Ridge regressions to predict the serum concentration of each PFAS in females and males using data of (1) socio-demographic and reproductive history, (2) diet, (3) behavioral factors, and (4) all factors included in (1) to (3) after accounting for temporal exposure trends. We used general linear models for univariate association of each factor with the PFAS concentration. We found moderate to high correlations for PFAS concentrations within couples. Among all examined factors, diet explained more of the variation in PFAS concentrations (1-48%), while behavioral factors explained the least (0-4%). Individuals reporting White race, with a higher body mass index, and nulliparous women had higher PFAS concentrations than others. Fish and shellfish consumption was positively associated with PFAS concentrations among both females and males, while intake of beans (females), peas (male), kale (females), and tortilla (both) was inversely associated with PFAS concentrations. Our findings provide important data for identifying sources of couples' PFAS exposure and informing interventions to reduce PFAS exposure in the preconception period.

Perinatal Exposure to Phenols and Poly- and Perfluoroalkyl Substances and Gut Microbiota in One-Year-Old Children.

The role of the gut microbiota in human health calls for a better understanding of its determinants. In particular, the possible effects of chemicals with widespread exposure other than pharmaceuticals are little known. Our aim was to characterize the sensitivity of the early-life gut microbiota to specific chemicals with possible antimicrobial action. Within the SEPAGES French couple-child cohort, we assessed 12 phenols in repeated urine samples from 356 pregnant women and their offspring and 19 poly- and perfluoroalkyl substances (PFASs) in serum from the pregnant women. We collected stool samples from the children at one year of age, in which the V3-V4 region of the 16S rRNA gene was sequenced, allowing for gut bacterial profiling. Associations of each chemical with α- and ß-diversity indices of the gut microbiota and with the relative abundance of the most abundant taxa were assessed using single-pollutant and mixture (BKMR) models. Perinatal exposure to certain parabens was associated with gut microbiota α- and ß-diversity and with Firmicutes and Proteobacteria. Suggestive associations of certain phenols with genera of the Lachnospiraceae and Enterobacteriaceae families were observed, but these were not maintained after correction for multiple testing. Parabens, which have known antimicrobial properties, might disrupt the child gut microbiota, but larger studies are required to confirm these findings.

What factors influence couples' decisions to have children? Evidence from a systematic scoping review.

BACKGROUND: One of the most significant demographic challenges over the past three decades has been the substantial reduction in fertility rates, worldwidely. As a developing country, Iran has also experienced a rapid decline in fertility over the past decades. Understanding factors influencing fertility is essential for development programs. Moreover, it's crucial to study the parameters that affect the intention for childbearing in any society. Therefore, through a systematic scoping review, the present study investigates the factors influencing couples' decisions toward childbearing. METHODS: This study was a systematic scoping review conducted in 2023. To design and conduct this scoping review, Joanna Briggs Institute's Protocol (Institute TJB, The Joanna Briggs Institute Reviewers ' manual 2015; methodology for JBI scoping reviews, 2015) was used and the framework presented by Levac et al. (2010) was also used as a guide for conducting this review. Studies were searched in three main databases including ISI Web of Sciences, PubMed, and Scopus, using a predefined search strategy. Google Scholar was also used for complementary search. The search period was from 2002 to 2022. RESULTS: A total of 18,454 studies were identified across three primary databases. After evaluating articles in three distinct phases based on title, abstract, and full-text, 46 articles were deemed eligible for inclusion in the scoping review. The qualitative analysis of the collected data from the selected studies through the scoping review led to classifying factors influencing households' desire for childbearing into eight main themes and 101 sub-themes. The main themes associated with factors impacting households' intention for childbearing encompass individual determinants, demographic and familial influencing factors, cultural elements, social factors, health-related aspects, economic considerations, insurance-related variables, and government support/incentive policies. CONCLUSIONS: Comprehensive and holistic attention from governments and officials toward the various factors affecting households' intention and behavior regarding childbearing appears beneficial and effective. Furthermore, given the relative ineffectiveness of some of the current government's supportive/incentive policies to increase couples' desire for childbearing, it seems necessary to review and amend these policies. This review should address the most significant challenges and factors contributing to couples' reluctance to childbearing or strengthen factors that can play a substantial role in fostering fertility and childbearing desires.

Sexological and traumatic aspects in reproductive difficulties: a psychometric study on couples seeking help for infertility.

PURPOSE: To investigate the impact of infertility in gender differences on psycho-traumatological, sexological, relational and emotional aspects and gender differences in couples requiring assisted reproductive treatment. METHODS: 151 couples were recruited with a mean age of 36.7 ± 4.8 years for women and 39.8 ± 6.6f or men. 43% of women and 34% of men had already received the diagnosis of infertility. To recruited subjects was administered the following psychometric tests: Sexological and Emotional in Infertility questionnaire (SEIq), Arizona Sexual Experience Scale (ASEX), the Orgasmomether and the International Trauma Questionnaire (ITQ). RESULTS: There was a significant difference in traumatic symptoms between men and women (t = 5,859, p < 0.05). Gender differences were found in the sexological dimension of the SEIq (t = 7,858, p < .001) and in the total ASEX score (t = 3,979, p < .001). Specifically, significant correlations emerged between the ASEX domains and the emotional and sexological aspects related to infertility only in women. The reaction to the diagnosis was negatively correlated with the emotional area of ​​the couple (r = -0.683, p < .001) and positively with the couple relationship (r = 0.815, p < .001). Multiple regression revealed that the overall functioning of the couple, rather than the single scales, is the main predictor of sexuality (R2 = 0.77). CONCLUSION: A clear impact of infertility on the couple's psycho-traumatological, psycho-sexological and relational aspects emerged. It could be useful to promote targeted support interventions on the most compromised areas of couple functioning in assisted reproductive centers.

Barriers, Facilitators, and Strategies to Improve Participation of a Couple-Based Intervention to Address Women's Antiretroviral Therapy Adherence in KwaZulu-Natal, South Africa.

BACKGROUND: Couple-based interventions (CBIs), despite strong efficacy in improving numerous HIV risk behaviors, are not widely available and have not been tested to improve women's antiretroviral therapy (ART) adherence. We examined barriers and facilitators to participation in a CBI based on cognitive behavioral couple therapy for women's ART adherence in KwaZulu-Natal, South Africa. METHODS: Semi-structured interviews were conducted with women with HIV (n = 15) and men of mixed HIV status (n = 15). Thematic analyses were guided by the Consolidated Framework for Implementation Research. RESULTS: Facilitators mostly related to the couple's relationship, including having an existing healthy relationship, men's desire to support their partners, and a potential opportunity for men's HIV disclosure. Barriers included a lack of understanding of how a CBI approach would be useful for women's ART adherence, sole focus on women if male partners were also living with HIV, and men's lack of prior HIV status disclosure to female partners. CONCLUSION: Findings indicate that relationship context and the male partner's HIV status need to be addressed during recruitment, enrolment, and during the intervention to promote uptake.

A Comprehensive and Longitudinal View of Pregnancy from the Perspective of the Couple, Maternal Mental Health and Fetal Growth.

OBJECTIVE: This study investigates the impact of both maternal psychopathological factors and adaptive psychological changes within the couple on fetal growth, emphasizing the importance of evaluating pregnancy from the perspectives of the couple, the mother, and the fetus collectively. A "couple" in this context refers to heterosexual partners engaged in the pregnancy process together, whether married or in a stable relationship. METHODS: We included 189 pregnant women in their first trimester, tracking maternal depression, anxiety, body appreciation, prenatal attachment, and the couple's adjustment level across each trimester. Fetal growth parameters measured include biparietal diameter, femur length, humerus length, abdomen circumference, head circumference, ß-HCG, and amniotic fluid levels, with relationships between these variables being modeled accordingly. RESULTS: Our findings indicate stable levels of maternal depression, anxiety, body appreciation, and couple's adjustment throughout the pregnancy, with a significant increase in prenatal attachment levels in each subsequent trimester. Prenatal attachment in the first trimester and maternal depression levels in the second and third trimesters were found to directly influence fetal growth, while other variables exhibited indirect effects. CONCLUSIONS: Fetal growth is influenced by a myriad of biopsychosocial factors. Ensuring healthy pregnancy and fetal development necessitates close monitoring and support of the mother's adaptive psychological changes, early identification and treatment of potential psychopathologies, and maintenance of the psychosocial health of the couple.

An integrated theory based-educational intervention to change intention to have a child: study protocol of a cluster randomized controlled trial.

BACKGROUND: In high- and low-income countries, declining birth rates have become a global concern. Couples do not have enough information about the complications of delaying and reducing childbearing and this leads them to make inappropriate decisions. Therefore, this study aims to evaluate whether an educational program based on integrating the Theory of Planned Behavior (TPB) and the Trans-Theoretical Model (TTM) affects child-free couples' intention to have children and minimizes the consequences of this decline. METHODS: Thirty couples (intervention, n = 15; control, n = 15) will be enrolled in this cluster randomized controlled trial. After collecting baseline data and separating participants in the pre-contemplation and contemplation stages based on the TTM, the samples were randomly assigned to the intervention and control groups. The intervention group will receive 60-min training based on TPB components for 4 weeks. The first follow-up assessment was performed immediately after the intervention and the final assessment 6 months later. For all 3 time assessments, three questionnaires will be used: The knowledge questionnaire, the TTM, and the TPB questionnaire. The most important consequences are changes in knowledge, attitudes, subjective norms, perceived behavioral control, and stages of intentions to have children. DISCUSSION: Decision-makers will use the results of this study as a basis to design appropriate, transparent, and useful policies and interventions to improve or stop the decline of the fertility rate at the national level. Also, this study will help young couples who wish to have a child in their lifetime by providing relevant information so that they do not miss this opportunity and face the consequences of delaying having a child. Trial registration This study was approved by the Iranian Registry of Clinical Trials (IRCT), Number: IRCT20220618055210N2, Date of registration: 2023-10-03.

Psychosocial and environmental motivational key factors behind the parenthood desire in infertile couples at the time of COVID-19.

PURPOSE: To evaluate the main psychosocial motivational factors behind the increased adoption of IVF during the COVID-19 pandemic. METHODS: This prospective, multicenter, observational case-control study assessed the factors motivating infertile couples to pursue their first IVF treatment during the pandemic across various IVF clinics in Spain, Portugal, Italy, the USA, and Panama. A pre-pandemic control group and a post-pandemic participant group were surveyed. The study was conducted between November 2021 and January 2023. The increase in IVF cycles was analyzed, and an ad hoc survey was developed to explore the motivational factors driving IVF engagement. RESULTS: Most clinics reported a significant increase in IVF demand (5.5-8.7%) for all indicators, including the number of started ovarian stimulations, oocyte pickups, and embryo transfers, following the declaration of the pandemic. The extra time spent and the reduced workload were the most important motivations prompting women to pursue their first fertility treatment during the pandemic (time to spend in the couple's relationship-OR, 1.53; 95% CI, 1.06-2.20; p < 0.05; decreased workload-OR, 2.63; 95% CI, 1.11-6.24; p < 0.05). CONCLUSION: This study highlights that infertility remains a significant stressor for individuals, and the desire to resolve it is not hindered by catastrophic events like COVID-19. Open communication between partners about reproductive intentions, combined with reduced work-related stress, is a key factor influencing the initiation of fertility treatment. It is crucial to encourage couples to take timely action in facing infertility.

Endometriosis: patient-doctor communication and psychological counselling.

The fact that endometriosis is one of the most frequent gynaecological disorders in women and girls is gradually attracting greater public and political attention. There is also substantial awareness of the disorder among German gynaecologists, albeit without sufficient "equipment" for discussing the condition with patients and providing psychological counselling. This article offers hands-on proposals for medical counselling and the discussion of relevant issues, as well as other practical tips and suggested verbalisations for use by women suffering from endometriosis (and their partners). These practical recommendations will certainly help to improve the doctor-patient relationship in the case of endometriosis. The resources mentioned below (guidebooks, websites) focus on German-language offerings only.

On-site preparation of sandwich plasmonic coupled SERS tape toward pesticide residue determination on food surface.

A sandwich plasmonic coupled surface enhanced Raman spectroscopy (SERS) tape is proposed prepared by peeling the chemical printed silver nanocorals (AgNCs) from Cu sheet with adhesive tape, which can sample targets from food surface and sandwich them between substrates and Cu sheet for SERS detection. The solid-to-solid transformation method for fabricating SERS tapes can effectively avoid the weakening of tape stickiness during the preparation process. The sandwich plasmonic coupled structure of AgNC substrate, targets, and Cu sheet display excellent SERS activity (EF = 1.62 × 107) for sensitive determination of analytes. In addition, due to the high heat conductivity of Cu sheet, the thermal effect of laser irradiation during SERS detection cannot damage the AgNC tapes, which ensures the reproducibility of subsequent quantification. The sandwich plasmonic coupled SERS tape is demonstrated to quantify malachite green (MG) and methyl parathion (MP) with good linear coefficients (> 0.98) by two typical calibration plots under different concentration ranges. The limit of detection (LOD) of the method is 0.17 ng/cm2 and 0.48 µg/cm2 (S/N = 3) for MG and MP. This method can realize the quantitative determination of MP and MG on the surface of fruits and fish scale with recoveries of 93-113%. The satisfactory detection results demonstrate the proposed sandwich plasmonic coupled AgNC tape can be successfully applied to SERS-based point-of-care testing (POCT) for pesticide residue determination, which will provide a new path for designing and constructing SERS tapes.
