Caregiver preferences for physically harsh discipline of children in rural Uganda.

Purpose: Physically harsh discipline is associated with poor developmental outcomes among children. These practices are more prevalent in areas experiencing poverty and resource scarcity, including in low- and middle-income countries. Designed to limit social desirability bias, this cross-sectional study in rural Uganda estimated caregiver preferences for physically harsh discipline; differences by caregiver sex, child sex, and setting; and associations with indicators of household economic stress and insecurity. Method: Three-hundred-fifty adult caregivers were shown six hypothetical pictographic scenarios depicting children whining, spilling a drink, and kicking a caregiver. Girls and boys were depicted engaging in each of the three behaviors. Approximately half of the participants were shown scenes from a market setting and half were shown scenes from a household setting. For each scenario, caregivers reported the discipline strategy they would use (time out, beating, discussing, yelling, ignoring, slapping). Results: Two thirds of the participants selected a physically harsh discipline strategy (beating, slapping) at least once. Women selected more physically harsh discipline strategies than men (b = 0.40; 95% confidence interval [CI], 0.26 to 0.54). Participants shown scenes from the market selected fewer physically harsh discipline strategies than participants shown scenes from the household (b = -0.51; 95% CI, -0.69 to -0.33). Finally, caregivers selected more physically harsh discipline strategies in response to boys than girls. Indicators of economic insecurity were inconsistently associated with preferences for physically harsh discipline. Conclusions: The high prevalence of physically harsh discipline preferences warrant interventions aimed at reframing caregivers' approaches to discipline.

Scarcity of fixed carbon transfer in a model microbial phototroph-heterotroph interaction.

Although the green alga Chlamydomonas reinhardtii has long served as a reference organism, few studies have interrogated its role as a primary producer in microbial interactions. Here, we quantitatively investigated C. reinhardtii's capacity to support a heterotrophic microbe using the established coculture system with Mesorhizobium japonicum, a vitamin B12-producing α-proteobacterium. Using stable isotope probing and nanoscale secondary ion mass spectrometry (nanoSIMS), we tracked the flow of photosynthetic fixed carbon and consequent bacterial biomass synthesis under continuous and diurnal light with single-cell resolution. We found that more 13C fixed by the alga was taken up by bacterial cells under continuous light, invalidating the hypothesis that the alga's fermentative degradation of starch reserves during the night would boost M. japonicum heterotrophy. 15NH4 assimilation rates and changes in cell size revealed that M. japonicum cells reduced new biomass synthesis in coculture with the alga but continued to divide - a hallmark of nutrient limitation often referred to as reductive division. Despite this sign of starvation, the bacterium still synthesized vitamin B12 and supported the growth of a B12-dependent C. reinhardtii mutant. Finally, we showed that bacterial proliferation could be supported solely by the algal lysis that occurred in coculture, highlighting the role of necromass in carbon cycling. Collectively, these results reveal the scarcity of fixed carbon in this microbial trophic relationship (particularly under environmentally relevant light regimes), demonstrate B12 exchange even during bacterial starvation, and underscore the importance of quantitative approaches for assessing metabolic coupling in algal-bacterial interactions.

Nurturing families: A feasibility randomised controlled trial of a whole-family intervention with vulnerable families in Jordan.

Armed conflict and forced displacement can significantly strain nurturing family environments, which are essential for child well-being. Yet, limited evidence exists on the effectiveness of family-systemic interventions in these contexts. We conducted a two-arm, single-masked, feasibility Randomised Controlled Trial (fRCT) of a whole-family intervention with Syrian, Iraqi and Jordanian families in Jordan. We aimed to determine the feasibility of intervention and study procedures to inform a fully-powered RCT. Eligible families were randomised to receive the Nurturing Families intervention or enhanced usual care (1:1). Masked assessors measured outcomes at baseline and endline; primary outcome measures were caregiver psychological distress, family functioning, and parenting practices. Families and implementing staff participated in qualitative interviews at endline. Of the 62 families screened, 60 (98%) were eligible, 97% completed the baseline and 90% completed the endline. Qualitative feedback indicated specific improvements in adolescent well-being, caregiver distress and parenting, and family relationships. Data highlighted high participant engagement and adequate facilitator fidelity and competence. Outcome measures had good psychometric properties (most α > 0.80) and sensitivity to change, with significant changes seen on most measures in the intervention but not control group. Findings indicate the acceptability and feasibility of intervention and study procedures. Subsequent full-scale evaluation is needed to determine effectiveness.

Identifiability of spatiotemporal tissue perfusion models.

Objective.Standard models for perfusion quantification in DCE-MRI produce a bias by treating voxels as isolated systems. Spatiotemporal models can remove this bias, but it is unknown whether they are fundamentally identifiable. The aim of this study is to investigate this question in silico using one-dimensional toy systems with a one-compartment blood flow model and a two-compartment perfusion model.Approach.For each of the two models, identifiability is explored theoretically and in-silico for three systems. Concentrations over space and time are simulated by forward propagation. Different levels of noise and temporal undersampling are added to investigate sensitivity to measurement error. Model parameters are fitted using a standard gradient descent algorithm, applied iteratively with a stepwise increasing time window. Model fitting is repeated with different initial values to probe uniqueness of the solution. Reconstruction accuracy is quantified for each parameter by comparison to the ground truth.Main results.Theoretical analysis shows that flows and volume fractions are only identifiable up to a constant, and that this degeneracy can be removed by proper choice of parameters. Simulations show that in all cases, the tissue concentrations can be reconstructed accurately. The one-compartment model shows accurate reconstruction of blood velocities and arterial input functions, independent of the initial values and robust to measurement error. The two-compartmental perfusion model was not fully identifiable, showing good reconstruction of arterial velocities and input functions, but multiple valid solutions for the perfusion parameters and venous velocities, and a strong sensitivity to measurement error in these parameters.Significance.These results support the use of one-compartment spatiotemporal flow models, but two-compartment perfusion models were not sufficiently identifiable. Future studies should investigate whether this degeneracy is resolved in more realistic 2D and 3D systems, by adding physically justified constraints, or by optimizing experimental parameters such as injection duration or temporal resolution.

Pregnancy Management in HIV Viral Controllers: Twenty Years of Experience.

(1) Background: The evidence base for the management of spontaneous viral controllers in pregnancy is lacking. We describe the management outcomes of pregnancies in a series of UK women with spontaneous HIV viral control (<100 copies/mL 2 occasions before or after pregnancy off ART). (2) Methods: A multi-centre, retrospective case series (1999-2021) comparing pre- and post-2012 when guidelines departed from zidovudine-monotherapy (ZDVm) as a first-line option. Demographic, virologic, obstetric and neonatal information were anonymised, collated and analysed in SPSS. (3) Results: A total of 49 live births were recorded in 29 women, 35 pre-2012 and 14 post. HIV infection was more commonly diagnosed in first reported pregnancy pre-2012 (15/35) compared to post (2/14), p = 0.10. Pre-2012 pregnancies were predominantly managed with ZDVm (28/35) with pre-labour caesarean section (PLCS) (24/35). Post-2012 4/14 received ZDVm and 10/14 triple ART, p = 0.002. Post-2012 mode of delivery was varied (5 vaginal, 6 PLCS and 3 emergency CS). No intrapartum ZDV infusions were given post-2012 compared to 11/35 deliveries pre-2012. During pregnancy, HIV was detected (> 50 copies/mL) in 14/49 pregnancies (29%) (median 92, range 51-6084). Neonatal ZDV post-exposure prophylaxis was recorded for 45/49 infants. No transmissions were reported. (4) Conclusion: UK practice has been influenced by the change in guidelines, but this has had little impact on CS rates.

Aging in Place and 'The Little Things': Prioritizing Mobile Health and Social Care in Rural Communities.

Older adults are more frequently wanting to age in place. Governments are seeking cost-effective and efficient methods of supporting aging populations. Older adults who want to stay in their homes for as long as possible encounter multiple barriers, including struggling to maintain their homes, inadequate levels of social and healthcare support, and the lack of financial capacity to pay for home support services. The Mobile Seniors' Wellness Network (MSWN), a multi-disciplinary and person-centered mobile health and social support intervention study was designed to investigate and support aging in place for older adults living in rural New Brunswick, Canada. Secondary analysis of case notes and exit interviews using content analysis revealed concerns with the lack of affordable and mobile care services for vulnerable rural older adults. Older adults revealed that their needs include "the little things" rather than grand gestures or sweeping policies to age in place such as assistance with grounds and home maintenance, in addition to relational and person-centered health and social care in the home. Reliance on private service delivery and volunteer organizations can increase the likelihood that older adults will experience a breakdown of social support networks tied together loosely by friends, family, and their communities. When services are unattainable aging in place becomes an unreachable goal.

A Pilot Study of the Coping Together Virtual Family Intervention: Exploring Changes in Family Functioning and Individual Well-Being.

In this pilot study, we tested a virtual family strengthening and mental health promotion intervention, Coping Together (CT), during the COVID-19 pandemic. We explored changes at the family and individual levels, as well as mechanisms of change. Participants included 18 families (24 caregivers, 24 youth) with children aged 7 to 18 years. Community health workers delivered the 8-session CT intervention using videoconferencing software. We used qualitative semi-structured interviews with 14 of the families to explore changes and mechanisms of change using a thematic content analysis approach. We also administered pre-post surveys with the 18 families to explore the direction of changes, using only descriptive statistics in this small sample. Qualitative findings supported positive changes across family and individual level outcomes including family functioning, relationship quality, and individual psychosocial well-being. Results also confirmed several hypothesized mechanisms of change with improved communication providing the foundation for increased hope and improved problem solving and coping. Pre-post survey results were mixed, showing positive, but very small, changes in family closeness, caregiver-child communication, and levels of hope; almost no change was observed on measures of caregiver and child mental health. Families reported few problems at baseline quantitatively despite qualitative descriptions of pre-intervention difficulties. Results provide preliminary support for benefits of CT with the most consistent improvements seen across family relationships. Findings were mixed related to individual-level mental health benefits. Results have implications for revising content on mental health coping strategies and suggest the need to revise the quantitative measurement strategy for this non-clinical sample.

Global Is Local: Leveraging Global Mental-Health Methods to Promote Equity and Address Disparities in the United States.

Structural barriers perpetuate mental health disparities for minoritized US populations; global mental health (GMH) takes an interdisciplinary approach to increasing mental health care access and relevance. Mutual capacity building partnerships between low and middle-income countries and high-income countries are beginning to use GMH strategies to address disparities across contexts. We highlight these partnerships and shared GMH strategies through a case series of said partnerships between Kenya-North Carolina, South Africa-Maryland, and Mozambique-New York. We analyzed case materials and narrative descriptions using document review. Shared strategies across cases included: qualitative formative work and partnership-building; selecting and adapting evidence-based interventions; prioritizing accessible, feasible delivery; task-sharing; tailoring training and supervision; and mixed-method, hybrid designs. Bidirectional learning between partners improved the use of strategies in both settings. Integrating GMH strategies into clinical science-and facilitating learning across settings-can improve efforts to expand care in ways that consider culture, context, and systems in low-resource settings.

Experiences of childhood, intimate partner, non-partner, and hate crime-related violence among a sample of people living with HIV in the epicenter of the U.S. HIV epidemic.

Introduction: Experiences of violence among people living with HIV (PLWH) are thought to be highly prevalent but remain inadequately captured. As a first step toward acceptable, trauma informed practices that improve engagement and retention in care for PLWH, we must acquire more comprehensive understanding of violence experiences. We examined experiences of various forms of lifetime violence: adverse childhood experiences (ACES), intimate partner violence (IPV), non-partner violence (NPV), and hate crimes among diverse sample of PLWH in Atlanta, Georgia. Methods: Cross sectional data collected from in- and out-of-care PLWH (N = 285) receiving care/support from Ryan White Clinics (RWCs), AIDS Service Organizations (ASOs), or large safety-net hospital, February 2021-December 2022. As part of larger study, participants completed interviewer-administered survey and reported on experiences of violence, both lifetime and past year. Participant characteristics and select HIV-related variables were collected to further describe the sample. Univariate and bivariate analyses assessed participant characteristics across types of violence. Results: High prevalence of past violence experiences across all types (ACES: 100%, IPV: 88.7%, NPV: 97.5%, lifetime hate crimes 93.2%). People assigned male at birth who identified as men experienced more violence than women, with exception of non-partner forced sex. Participants identifying as gay men were more likely to have experienced violence. Conclusion: Among our sample of PLWH at the epicenter of the United States HIV epidemic, histories of interpersonal and community violence are common. Findings emphasize need for RWCs, ASOs, and hospital systems to be universally trained in trauma-informed approaches and have integrated onsite mental health and social support services.

Correlates of Intimate Partner Violence Victimization and Perpetration in Adolescents and Young Adults in Sub-Saharan Africa: A Systematic Review.

Intimate partner violence (IPV) is a global public health crisis with long-term adverse consequences for both victims and perpetrators. Patterns of violence often begin during adolescence, yet most interventions target adult relationships. A systematic review was conducted to identify correlates of IPV victimization and perpetration among adolescents and young adults in sub-Saharan Africa (SSA). Eligible studies included participants 10 to 24 years old, took place in SSA, and tested a statistical association between a correlate and an IPV outcome. Correlates were defined as any condition or characteristic associated with statistically significant increased or decreased risk of IPV victimization or perpetration. PsycInfo, PubMed, Embase, and African Index Medicus were searched and included studies published between January 1, 2000 and February 4, 2022. The search resulted in 3,384 original studies, of which 55 met inclusion criteria and were analyzed. Correlates were first qualitatively synthesized by developmental period (e.g., early adolescence, older adolescence, and young adulthood) and then organized in a conceptual framework by correlate type (e.g., socio-demographic; health, behavior, and attitudes; relational; or contextual). Over two decades of literature reveals variability in evidence by developmental period but also substantial overlap in the correlates of victimization and perpetration. This review identifies multiple points for intervention and results suggest the urgent need for earlier, developmentally appropriate prevention efforts among younger adolescents as well as combined approaches that target both victimization and perpetration of IPV.

Current status in spatiotemporal analysis of contrast-based perfusion MRI.

In perfusion MRI, image voxels form a spatially organized network of systems, all exchanging indicator with their immediate neighbors. Yet the current paradigm for perfusion MRI analysis treats all voxels or regions-of-interest as isolated systems supplied by a single global source. This simplification not only leads to long-recognized systematic errors but also fails to leverage the embedded spatial structure within the data. Since the early 2000s, a variety of models and implementations have been proposed to analyze systems with between-voxel interactions. In general, this leads to large and connected numerical inverse problems that are intractible with conventional computational methods. With recent advances in machine learning, however, these approaches are becoming practically feasible, opening up the way for a paradigm shift in the approach to perfusion MRI. This paper seeks to review the work in spatiotemporal modelling of perfusion MRI using a coherent, harmonized nomenclature and notation, with clear physical definitions and assumptions. The aim is to introduce clarity in the state-of-the-art of this promising new approach to perfusion MRI, and help to identify gaps of knowledge and priorities for future research.

The ISMRM Open Science Initiative for Perfusion Imaging (OSIPI): Results from the OSIPI-Dynamic Contrast-Enhanced challenge.

PURPOSE: K trans $$ {K}^{\mathrm{trans}} $$ has often been proposed as a quantitative imaging biomarker for diagnosis, prognosis, and treatment response assessment for various tumors. None of the many software tools for K trans $$ {K}^{\mathrm{trans}} $$ quantification are standardized. The ISMRM Open Science Initiative for Perfusion Imaging-Dynamic Contrast-Enhanced (OSIPI-DCE) challenge was designed to benchmark methods to better help the efforts to standardize K trans $$ {K}^{\mathrm{trans}} $$ measurement. METHODS: A framework was created to evaluate K trans $$ {K}^{\mathrm{trans}} $$ values produced by DCE-MRI analysis pipelines to enable benchmarking. The perfusion MRI community was invited to apply their pipelines for K trans $$ {K}^{\mathrm{trans}} $$ quantification in glioblastoma from clinical and synthetic patients. Submissions were required to include the entrants' K trans $$ {K}^{\mathrm{trans}} $$ values, the applied software, and a standard operating procedure. These were evaluated using the proposed OSIP I gold $$ \mathrm{OSIP}{\mathrm{I}}_{\mathrm{gold}} $$ score defined with accuracy, repeatability, and reproducibility components. RESULTS: Across the 10 received submissions, the OSIP I gold $$ \mathrm{OSIP}{\mathrm{I}}_{\mathrm{gold}} $$ score ranged from 28% to 78% with a 59% median. The accuracy, repeatability, and reproducibility scores ranged from 0.54 to 0.92, 0.64 to 0.86, and 0.65 to 1.00, respectively (0-1 = lowest-highest). Manual arterial input function selection markedly affected the reproducibility and showed greater variability in K trans $$ {K}^{\mathrm{trans}} $$ analysis than automated methods. Furthermore, provision of a detailed standard operating procedure was critical for higher reproducibility. CONCLUSIONS: This study reports results from the OSIPI-DCE challenge and highlights the high inter-software variability within K trans $$ {K}^{\mathrm{trans}} $$ estimation, providing a framework for ongoing benchmarking against the scores presented. Through this challenge, the participating teams were ranked based on the performance of their software tools in the particular setting of this challenge. In a real-world clinical setting, many of these tools may perform differently with different benchmarking methodology.

Adapting a substance use screening and brief intervention for peer-delivery and for youth in Kenya.

Background: Substance use is a major problem among youth in sub-Saharan Africa, yet interventions that address this problem are scarce within the region. Screening and brief intervention is a cost-effective, efficacious, and easy to scale public health approach to addressing substance use problems. We conducted a pilot study to evaluate the feasibility of implementing a peer delivered screening and brief intervention program for youth in Kenya. The goal of this paper is to report on the process of adapting the Alcohol Smoking and Substance Involvement Screening Test for Youth- linked Brief Intervention (ASSIST-Y-linked BI) program for peer delivery and for the Kenyan context prior to the pilot. Methods: The adaptation process was led by a multi-disciplinary team comprised of psychiatrists, pediatricians, and psychologists. We utilized the ADAPT-ITT framework to adapt the ASSIST-Y-linked BI. The ADAPT-ITT framework consists of 8 phases including Assessment, Decision making, Adaptation, Production, Topical Experts, Integration, Training, and Testing the evidence-based intervention. Here, we report on phases 1-7 of the framework. The results of the pilot testing have been published elsewhere. Results: Overall, we made surface level adaptations to the ASSIST-Y-linked BI program such as simplifying the language to enhance understandability. We maintained the core components of the program i.e., Feedback, Responsibility, Advice, Menu of Options, Empathy, Self-efficacy (FRAMES). Conclusions: Our paper provides information which other stakeholders planning to implement the ASSIST-Y-linked BI for youth in sub-Saharan Africa, could use to adapt the intervention.

Social Vulnerability, COVID-19, Racial Violence, and Depressive Symptoms: a Cross-sectional Study in the Southern United States.

BACKGROUND: In March 2020, the novel 2019 coronavirus disease (COVID-19) was declared a pandemic. In May 2020, George Floyd was murdered, catalyzing a national racial reckoning. In the Southern United States, these events occurred in the context of a history of racism and high rates of poverty and discrimination, especially among racially and ethnically minoritized populations. OBJECTIVES: In this study, we examine social vulnerabilities, the perceived impacts of COVID-19 and the national racial reckoning, and how these are associated with depression symptoms in the South. METHODS: Data were collected from 961 adults between June and November 2020 as part of an online survey study on family well-being during COVID-19. The sample was majority female (87.2%) and consisted of 661 White participants, 143 Black participants, and 157 other racial and ethnic minoritized participants. Existing social vulnerability, perceived impact of COVID-19 and racial violence and protests on families, and depressive symptoms were assessed. Hierarchical regression analysis was used to predict variance in depressive symptoms. RESULTS: Half of the sample (52%) reported a negative impact of COVID-19, and 66% reported a negative impact of national racial violence/protests. Depressive symptoms were common with 49.8% meeting the cutoff for significant depressive symptoms; Black participants had lower levels of depressive symptoms. Results from the hierarchical regression analysis indicate social vulnerabilities and the perceived negative impact of COVID-19 and racial violence/protests each contribute to variance in depressive symptoms. Race-specific sensitivity analysis clarified distinct patterns in predictors of depressive symptoms. CONCLUSION: People in the South report being negatively impacted by the confluence of the COVID-19 pandemic and the emergence of racial violence/protests in 2020, though patterns differ by racial group. These events, on top of pre-existing social vulnerabilities, help explain depressive symptoms in the South during 2020.

Effective training practices for non-specialist providers to promote high-quality mental health intervention delivery: A narrative review with four case studies from Kenya, Ethiopia, and the United States.

Mental health needs and disparities are widespread and have been exacerbated by the COVID-19 pandemic, with the greatest burden being on marginalized individuals worldwide. The World Health Organization developed the Mental Health Gap Action Programme to address growing global mental health needs by promoting task sharing in the delivery of psychosocial and psychological interventions. However, little is known about the training needed for non-specialists to deliver these interventions with high levels of competence and fidelity. This article provides a brief conceptual overview of the evidence concerning the training of non-specialists carrying out task-sharing psychosocial and psychological interventions while utilizing illustrative case studies from Kenya, Ethiopia, and the United States to highlight findings from the literature. In this article, the authors discuss the importance of tailoring training to the skills and needs of the non-specialist providers and their roles in the delivery of an intervention. This narrative review with four case studies advocates for training that recognizes the expertise that non-specialist providers bring to intervention delivery, including how they promote culturally responsive care within their communities.

Assessing ad-hoc adaptations' alignment with therapeutic goals: a qualitative study of lay counselor-delivered family therapy in Eldoret, Kenya.

BACKGROUND: A key question in implementation science is how to balance adaptation and fidelity in translating interventions to new settings. There is growing consensus regarding the importance of planned adaptations to deliver interventions in contextually sensitive ways. However, less research has examined ad-hoc adaptations, or those that occur spontaneously in the course of intervention delivery. A key question is whether ad-hoc adaptations ultimately contribute to or detract from intervention goals. This study aimed to (a) identify ad-hoc adaptations made during delivery of a family therapy intervention and (b) assess whether they promoted or interrupted intervention goals. METHODS: Tuko Pamoja (Swahili: "We are Together") is an evidence-informed family therapy intervention aiming to improve family dynamics and mental health in Kenya. Tuko Pamoja employs a task-shifting model, delivered by lay counselors who are afforded a degree of flexibility in presenting content and in practices they use in sessions. We used transcripts of therapy sessions with 14 families to examine ad-hoc adaptations used by counselors. We first identified and characterized ad-hoc adaptations through a team-based code development, coding, and code description process. Then, we evaluated to what extent ad-hoc adaptations promoted the principles and strategies of the intervention ("TP-promoting"), disrupted them ("TP-interrupting"), or neither ("TP-neutral"). To do this, we first established inter-coder agreement on application of these categories with verification by the intervention developer. Then, coders categorized ad-hoc adaptation text segments as TP-promoting, TP-interrupting, or TP-neutral. RESULTS: Ad-hoc adaptations were frequent and included (in decreasing order): incorporation of religious content, exemplars/role models, community dynamics and resources, self-disclosure, and metaphors/proverbs. Ad-hoc adaptations were largely TP-promoting (49%) or neutral (39%), but practices were TP-interrupting 12% of the time. TP-interrupting practices most often occurred within religious content and exemplars/role models, which were also the most common practices overall. CONCLUSION: Extra attention is needed during planned adaptation, training, and supervision to promote intervention-aligned use of common ad-hoc adaptation practices. Discussing them in trainings can provide guidance for lay providers on how best to incorporate ad-hoc adaptations during delivery. Future research should evaluate whether well-aligned ad-hoc adaptations improve therapeutic outcomes. TRIAL REGISTRATION: Pilot trial registered at clinicaltrials.gov (C0058).

Predictors of harsh parenting practices and inter-partner conflict during the COVID-19 pandemic in Ontario, Canada: a cross-sectional analysis from the Ontario Parent Survey.

OBJECTIVES: Guided by the bioecological model, the purpose of this study was to examine the associations of (1) individual level factors (sociodemographic, health behaviour and mental health), (2) family (micro) level COVID-19 experiences (difficulty with household management, managing child mood and behaviour, and pandemic-related positive experiences) and (3) community (macro) level factors (residential instability, ethnic concentration, material deprivation and dependency, an indicator of age and labour force) with harsh parenting practices and inter-partner conflict during the early lockdown of the COVID-19 pandemic in Ontario, Canada. DESIGN: A cross-sectional analysis of data from the Ontario Parent Survey. SETTING: A convenience sample of 7451 caregivers living in Ontario, Canada, at the time of baseline data collection (May-June 2020). PARTICIPANTS: Caregivers aged 18 years and older with children 17 years or younger. OUTCOME MEASURES: Parenting practices over the past 2 months was assessed using a published modification of the Parenting Scale. The frequency of inter-partner conflict over the past month was assessed using the Marital Conflict scale. RESULTS: Individual (sociodemographic factors, alcohol use, and higher depressive and anxiety symptoms) and family (difficulties with managing the household and child mood and behaviour) level factors were positively associated with inter-partner conflict and harsh parenting practices. Having fewer positive experiences (eg, performing activities with children), and economic adversity at the family level were positively associated with inter-partner conflict but inversely associated with harsh parenting. At the community level, residential instability was negatively associated with harsh parenting practices. CONCLUSIONS: Individual and family level factors were associated with harsh parenting and inter-partner conflict. The associations of fewer positive experiences and economic hardship with harsh parenting practices may be more complex than initially thought. Efforts that raise awareness and address caregiver mental health concerns are needed as part of the pandemic response to promote positive inter-partner and parent-child interactions.

Comparative analysis of vaginal microbiota sampling using menstrual cups and high vaginal swabs in pregnant women living with HIV-1 infection.

Background: Menstrual cups (MCs) are increasingly used to collect cervicovaginal secretions to characterise vaginal mucosal immunology, in conjunction with high vaginal swabs (HVS) for metataxonomics, particularly in HIV transmission studies. We hypothesised that both methods of collecting bacterial biomass are equivalent for 16S rRNA gene sequencing. Material and Methods: Cervicovaginal fluid (CVF) samples from 16 pregnant women with HIV-1 (PWWH) were included to represent the major vaginal bacterial community state types (CST I-V). Women underwent sampling during the second trimester by liquid amies HVS followed by a MC (Soft disc™) and samples were stored at -80°C. Bacterial cell pellets obtained from swab elution and MC (500 µL, 1 in 10 dilution) were resuspended in 120 µL PBS for DNA extraction. Bacterial 16S rRNA gene sequencing was performed using V1-V2 primers and were analysed using MOTHUR. Paired total DNA, bacterial load, amplicon read counts, diversity matrices and bacterial taxa were compared by sampling method using MicrobiomeAnalyst, SPSS and R. Results: The total DNA eluted from one aliquot of diluted CVF from an MC was similar to that of a HVS (993ng and 609ng, p=0.18); the mean bacterial loads were also comparable for both methods (MC: 8.0 log10 16S rRNA gene copies versus HVS: 7.9 log10 16S rRNA gene copies, p=0.27). The mean number of sequence reads generated from MC samples was lower than from HVS (MC: 12730; HVS:14830, p=0.05). The α-diversity metrices were similar for both techniques; MC Species Observed: 41 (range 12-96) versus HVS: 47 (range 16-96), p=0.15; MC Inverse Simpson Index: 1.98 (range 1.0-4.0) versus HVS: 0.48 (range 1.0-4.4), p=0.22). The three most abundant species observed were: Lactobacillus iners, Lactobacillus crispatus and Gardnerella vaginalis. Hierarchical clustering of relative abundance data showed that samples obtained using different techniques in an individual clustered in the same CST group. Conclusion: These data demonstrate that despite sampling slightly different areas of the lower genital tract, there was no difference in bacterial load or composition between methods. Both are suitable for characterisation of vaginal microbiota in PWWH. The MC offers advantages, including a higher volume of sample available for DNA extraction and complimentary assays.
