Genome-wide analysis of early vascular tunic repair and regeneration for Botrylloides digenesis reveals striking similarities to human wound healing.

The early stages of regeneration after injury are similar to those of wound healing. The ascidian Botrylloides diegensis can regenerate an entire adult from a small fragment of vascular tunic following the removal of all zooids in an injury-induced regeneration model. We investigated the molecular and cellular changes following injury to determine the differences between the healing process and the initiation of whole-body regeneration (WBR). We conducted transcriptome analysis at specific time points during regeneration and wound healing to identify differentially expressed genes (DEGs) and the unique biological processes associated with each state. Our findings revealed 296 DEGs at 10 h post-injury (hpi), with 71 highly expressed in healed tissue and 225 expressed during the WBR process. These DEGs were predicted to play roles in tissue reorganization, integrin signaling, extracellular matrix organization, and the innate immune system. Pathway analysis of the upregulated genes in the healed tunic indicated functional enrichment related to tissue repair, as has been observed in other species. Additionally, we examined the cell types in the tunic and ampullae in both tissue states using histology and in situ hybridization for six genes identified by transcriptome analysis. We observed strong mRNA expression in cells within the WBR tunic, and in small RNA-positive granules near the tunic edge. We hypothesized that many of these genes function in the compaction of the ampullae tunic, which is a pivotal process for WBR and dormancy in B. diegensis, and in an immune response. These findings establish surprising similarities between ascidian regeneration and human wound healing, emphasizing the potential for future investigations into human regenerative and repair mechanisms. This study provides valuable insights into the gene sets specifically activated during regeneration compared to wound healing, shedding light on the divergent activities of these processes.

Childhood adversity trajectories and weight status in young adult men: a register-based study including 359,783 Danish men.

BACKGROUND: Childhood adversity has previously been associated with overweight and obesity in adult life, but there is a need for larger population-based studies using prospectively obtained adversity trajectories across childhood to confirm these associations. Moreover, childhood adversity may also be associated with underweight, which is less often studied. The aim of the current study is to investigate the association between childhood adversity trajectories from 0-15 years with weight categories in young adult men. METHODS: The Danish Life Course Cohort (DANLIFE) was linked with the Danish Conscription Registry resulting in a study sample of 359,783 men, who have been assigned to one of five previously identified adversity trajectories from 0-15 years: "low adversity", "early material deprivation", "persistent material deprivation", "loss or threat of loss", and "high adversity". Height and weight in young adulthood was assessed at a draft board examination at age 18-26 years. Associations of adversity trajectories and weight categories were investigated in multinomial regression models. RESULTS: Compared with the "low adversity" group, the four other adversity groups had higher risks of underweight, overweight, and obesity. The "high adversity" group showed the strongest associations with both underweight (1.44 (1.32, 1.58)) and obesity (1.50 (1.39, 1.61)) when adjusted for parental origin, birth year, age at draft board examination, and maternal age. CONCLUSION: Childhood adversity, experienced between 0 and 15 years of life, was associated with a higher risk of underweight, overweight, and obesity in young adulthood among men.

Trauma-focused therapy in early psychosis: results of a feasibility randomized controlled trial of EMDR for psychosis (EMDRp) in early intervention settings.

BACKGROUND: Trauma is prevalent amongst early psychosis patients and associated with adverse outcomes. Past trials of trauma-focused therapy have focused on chronic patients with psychosis/schizophrenia and comorbid Post-Traumatic Stress Disorder (PTSD). We aimed to determine the feasibility of a large-scale randomized controlled trial (RCT) of an Eye Movement Desensitization and Reprocessing for psychosis (EMDRp) intervention for early psychosis service users. METHODS: A single-blind RCT comparing 16 sessions of EMDRp + TAU v. TAU only was conducted. Participants completed baseline, 6-month and 12-month post-randomization assessments. EMDRp and trial assessments were delivered both in-person and remotely due to COVID-19 restrictions. Feasibility outcomes were recruitment and retention, therapy attendance/engagement, adherence to EMDRp treatment protocol, and the 'promise of efficacy' of EMDRp on relevant clinical outcomes. RESULTS: Sixty participants (100% of the recruitment target) received TAU or EMDR + TAU. 83% completed at least one follow-up assessment, with 74% at 6-month and 70% at 12-month. 74% of EMDRp + TAU participants received at least eight therapy sessions and 97% rated therapy sessions demonstrated good treatment fidelity. At 6-month, there were signals of promise of efficacy of EMDRp + TAU v. TAU for total psychotic symptoms (PANSS), subjective recovery from psychosis, PTSD symptoms, depression, anxiety, and general health status. Signals of efficacy at 12-month were less pronounced but remained robust for PTSD symptoms and general health status. CONCLUSIONS: The trial feasibility criteria were fully met, and EMDRp was associated with promising signals of efficacy on a range of valuable clinical outcomes. A larger-scale, multi-center trial of EMDRp is feasible and warranted.

Interventions supporting engagement with sexual healthcare among people of Black ethnicity: a systematic review of behaviour change techniques.

BACKGROUND: Black ethnic groups are disproportionately affected by sexually transmitted infections (STIs). This review aimed to identify interventions designed to increase engagement with sexual healthcare among people of Black ethnicity as determined by rates of STI testing, adherence to sexual health treatment, and attendance at sexual healthcare consultations. The behaviour change techniques (BCTs) used within identified interventions were evaluated. METHOD: Four electronic databases (Web of science; ProQuest; Scopus; PubMed) were systematically searched to identify eligible articles published between 2000 and 2022. Studies were critically appraised using the Mixed Methods Appraisal Tool. Findings were narratively synthesised. RESULTS: Twenty one studies across two countries were included. Studies included randomised controlled trials and non-randomised designs. Behavioural interventions had the potential to increase STI/HIV testing, sexual healthcare consultation attendance and adherence to sexual health treatment. Behavioural theory underpinned 16 interventions which addressed barriers to engaging with sexual healthcare. Intervention facilitators' demographics and lived experience were frequently matched to those of recipients. The most frequently identified novel BCTs in effective interventions included information about health consequences, instruction on how to perform behaviour, information about social and environmental consequences, framing/reframing, problem solving, and review behavioural goal(s). DISCUSSION: Our findings highlight the importance of considering sociocultural, structural and socio-economic barriers to increasing engagement with sexual healthcare. Matching the intervention facilitators' demographics and lived experience to intervention recipients may further increase engagement. Examination of different BCT combinations would benefit future sexual health interventions in Black ethnic groups.

Barriers to engagement with testing for sexually transmitted infections within a UK-based young adult Black Caribbean community: a qualitative study.

BACKGROUND: The Black Caribbean population have a disproportionately high burden of sexually transmitted infections (STIs) compared with other ethnic groups. The aim of this study was to explore barriers to engagement with STI testing within a UK-based young adult Black Caribbean community. METHODS: Semi-structured interviews were carried out with 14 young adults from the Black Caribbean community and six sexual healthcare professionals. Data were analysed thematically. A focus group of five young adults was conducted to refine themes. RESULTS: Data analysis generated three themes: (1) culturally embedded stigma; (2) historically embedded mistrust; and (3) lack of knowledge. Perceived as 'dirty', particularly for females, infection with STIs was stigmatised by religious conceptions of 'purity' and shame. This presented challenges in terms of cultural acceptability of talking about STI testing with partners, friends, and family. Legacies of colonialism, medical racism and malpractice compromised young people's trust in medical intervention and confidentiality of data management. A lack of knowledge related to STIs and their treatment, and in how to access and perform STI tests further served as a barrier. Culturally tailored interventions targeting these factors and delivered by radio, podcasts and social media were highlighted as having potential to improve engagement with STI testing. DISCUSSION: Engagement with STI testing by young adults from the Black Caribbean community is impacted by historically and culturally embedded teachings, practices and beliefs inherited through generations. Targeting these factors within culturally tailored interventions may be effective for increasing STI-testing, and thus reducing rates of STI-infection in this population.

A trifecta: patterns in orgasm consistency, relational satisfaction, and sexual satisfaction.

BACKGROUND: We based this study on the sexual wholeness model, which considers emotional, physical, and meaning elements of sexuality, and previous research that indicates variability in the associations among orgasm consistency, relational satisfaction, and sexual satisfaction. AIM: We performed a person-based latent class approach to examine variables linked with the trifecta of orgasm consistency, relational satisfaction, and sexual satisfaction. METHODS: We used a Mechanical Turk sample that consisted of 1645 sexually active participants (1032 women) to evaluate classes and related variables. OUTCOMES: Women divided into 5 classes and men into 3 classes. High orgasm consistency alone did not ensure sexual or relational satisfaction. RESULTS: We found that 5 groups emerged for women: high orgasm/low satisfaction (6%), low trifecta (8%), low orgasm/high satisfaction (16%), moderate orgasm/high satisfaction (15%), and high trifecta (55%). For men, 3 groups emerged: lower orgasm/high satisfaction (12%), moderate trifecta (14%), and high trifecta (74%). We also found that high orgasm consistency for women did not guarantee relational and sexual satisfaction, nor did lower orgasm consistency for men or women guarantee problematic relational and sexual satisfaction. CLINICAL IMPLICATIONS: Communication, attachment, and sexual harmony were key elements associated with positive trifecta outcomes. Clinicians and educators may emphasize the importance of these variables when individuals encounter sexual or relational distress. STRENGTHS AND LIMITATIONS: Data analytic techniques revealed a variety of groups for men and women and associations between a host of physical, psychological, and meaning variables and the trifecta of orgasm consistency, relational satisfaction, and sexual satisfaction. However, this study is cross-sectional and correlational, which limits the conclusions that we can draw from it. CONCLUSION: While the variables of orgasm consistency, relational satisfaction, and sexual satisfaction are each informative, together they help clinicians, educators, and researchers better understand the complexity of sex.

Fluorescent α-amino acids via Heck-Matsuda reactions of phenylalanine-derived arenediazonium salts.

The Heck-Matsuda coupling reaction of arenediazonium salts derived from L-phenylalanine with various alkenes has been developed. A two-step process involving the preparation of a tetrafluoroborate diazonium salt from a 4-aminophenylalanine derivative, followed by a palladium(0)-catalysed Heck-Matsuda coupling reaction allowed access to a range of unnatural α-amino acids with cinnamate, vinylsulfone and stilbene side-chains. Analysis of the photophysical properties of these unnatural α-amino acids demonstrated that the (E)-stilbene analogues exhibited fluorescent properties with red-shifted absorption and emission spectra and larger quantum yields than L-phenylalanine.

Religiosity, Sexual Satisfaction, and Relationship Satisfaction: The Moderating Role of Sexual Mindfulness and Sexual Sanctification.

There are a variety of conditions under which religiosity may be positively or negatively associated with sexual and relationship satisfaction. To better understand these conditions, we conducted two studies using two separate samples: one with individuals (1,695 individuals), and one with couples (481 dyads), to test how sexual sanctification and sexual mindfulness moderate these associations. Across studies sexual mindfulness was positively associated with sexual and relationship satisfaction for the individual and partner, but there was no evidence for moderation; sexual sanctification was consistently associated with higher sexual and relationship satisfaction, and in some cases moderated the association between religiosity and both sexual and relationship satisfaction for women and men. In Study 1, religiosity was associated with lower sexual and relationship satisfaction for both men and women when sexual sanctification was low, but not with either type of satisfaction when sexual sanctification was high. In Study 2, religiosity was positively associated with sexual satisfaction for men but only when sexual sanctification was high. The combined evidence indicates that sexual sanctification may be one factor that distinguishes whether religion helps or hinders sexual and relationship satisfaction.

Factors influencing non-attendance at sexual healthcare appointments in the UK: a qualitative study.

BACKGROUND: Missed sexual healthcare appointments lead to inefficiencies and wasted resources, longer waiting times and poorer outcomes. The aim of this research was to identify factors influencing non-attendance at sexual healthcare appointments and to make recommendations for interventions. METHODS: Semi-structured interviews were carried out with UK-based sexual health service-users with experience of booking and missing appointments and sexual health professionals (n =28). Interviews were analysed using a thematic framework approach. RESULTS: Perceptual, practical, and organisational factors were found to influence missed appointments. Perceptual factors included beliefs about the outcomes of attending; sense of responsibility to attend; and concerns about privacy and security. Practical factors included competing demands and disruption to daily life; ability to attend; and forgetting. Organisational factors included mode of appointment delivery and availability of appointments. CONCLUSIONS: Interventions should combine strategies shown to be effective for overcoming practical barriers to attendance (e.g. reminder systems) with novel strategies communicating the benefits of attending and risks of missed appointments (e.g. behaviourally informed messaging). Text reminders containing behaviourally informed messages may be an efficient intervention for targeting perceptual and practical factors associated with missed appointments. Offering appointment modalities to suit individual preference and enabling service-users to remotely cancel/reschedule appointments maight further support a reduction in missed appointments.

Religious Piety and Sexual Passion: What Is the Connection?

The association between religiosity and the construct of sexual passion was examined to see whether religiosity is associated with harmonious, inhibited, and obsessive sexual passion styles. Using multiple regression and checking for interactions between religiosity, gender, broad categories of religion (Catholic, other Christian, other religious, nonreligious), and the three sexual passion styles, the following associations were found: Religiosity had a significant curvilinear relationship to all three sexual passion styles, suggesting an overlap in levels of religiosity and the construct of sexual passion. Optimal sexual passion outcomes were found at both higher and lower levels of religiosity, whereas mid-level religiosity was associated with the less beneficial sexual passion outcomes. Religious men were significantly more obsessively passionate than religious women, and religious men and women were similarly high on levels of harmonious and low on inhibited sexual passion. There were no significant interactions between religiosity, broad categories of religion, and sexual passion styles. Understanding how religion and sexual passion are associated could be useful for applied researchers as well as those who work with religious individuals who want to help these individuals develop beneficial patterns of sexual passion.

"He's not fat, he just has asthma": a qualitative study exploring weight management in families living with pediatric asthma.

ObjectiveChildren and young people living with asthma have an increased risk of overweight/obesity, leading to increased severity of asthma symptoms. Weight management has been recommended to improve asthma symptoms, however, there is limited understanding of how this is experienced or how children and young people with asthma and their families wish to be supported. The aim of this study was to explore parents and children/young people's views and experiences of managing weight while living with asthma, and to identify acceptable strategies for support.Methods: A qualitative methodological approach was taken to facilitate rich understanding of families' insights into weight management while living with asthma. In-depth interviews were conducted with nine families living with pediatric asthma (n = 9 parents, 9 young people). Data were analyzed using a Framework approach.Results: Findings indicated that family engagement with weight management behaviors was primarily influenced by perceptions of risk regarding asthma outcomes and beliefs about asthma control. Families also reported weight management engagement to be influenced by perceptions of the food environment, perceptions of the exercise environment (e.g. weather, anticipated social outcomes) and the availability of weight management support. Participants sought tailored support which gave consideration to the asthma-obesity interaction. It was suggested that this would help reduce perceptions of weight stigma in consultations, thereby supporting behavioral changes.Conclusions: Individualized weight management plans that consider families concerns about asthma-related risk are needed to manage weight in children and young people living with asthma.

Increasing attendance at pre-booked sexual health consultations: a systematic review.

BACKGROUND: Attending a sexual health consultation is integral to the effective prevention and treatment of sexually transmitted infections (STIs). However, individuals who may be at risk of STIs do not always do so, leading to an increased risk of STI complications and transmission of infection to others. This systematic review aimed to identify interventions implemented to increase attendance at a pre-booked sexual health clinic appointment and to identify behavioural theory and behaviour change techniques (BCTs), which form the basis for such interventions. METHODS: Articles were identified through a systematic search of four electronic databases (Web of Science; ProQuest; Scopus; PubMed) and included if they aimed to increase attendance at a pre-booked, synchronous sexual health consultation. The quality of included studies was assessed independently by two researchers. Findings were synthesised narratively. RESULTS: Thirteen studies were included from three countries; eight non-randomised before-after study designs and five randomised controlled trials. Behavioural interventions increased attendance at pre-booked sexual health consultations. Text messages were the most frequently used mode for intervention delivery. A total of 19 BCTs were identified, but only three studies mentioned behavioural theory. The most frequently used BCTs in effective interventions were: using credible sources, employing prompts/cues and the provision of information about health consequences. However, these BCTs were also identified in interventions that were not effective, meaning that optimal content and theoretical underpinning of effective interventions remains unclear. CONCLUSIONS: Behavioural interventions can increase attendance at sexual health consultations. Further research is needed to examine the effectiveness of different BCT combinations.

Machine Learning Models for Weight-Bearing Activity Type Recognition Based on Accelerometry in Postmenopausal Women.

Hip-worn triaxial accelerometers are widely used to assess physical activity in terms of energy expenditure. Methods for classification in terms of different types of activity of relevance to the skeleton in populations at risk of osteoporosis are not currently available. This publication aims to assess the accuracy of four machine learning models on binary (standing and walking) and tertiary (standing, walking, and jogging) classification tasks in postmenopausal women. Eighty women performed a shuttle test on an indoor track, of which thirty performed the same test on an indoor treadmill. The raw accelerometer data were pre-processed, converted into eighteen different features and then combined into nine unique feature sets. The four machine learning models were evaluated using three different validation methods. Using the leave-one-out validation method, the highest average accuracy for the binary classification model, 99.61%, was produced by a k-NN Manhattan classifier using a basic statistical feature set. For the tertiary classification model, the highest average accuracy, 94.04%, was produced by a k-NN Manhattan classifier using a feature set that included all 18 features. The methods and classifiers within this study can be applied to accelerometer data to more accurately characterize weight-bearing activity which are important to skeletal health.

RexAB Promotes the Survival of Staphylococcus aureus Exposed to Multiple Classes of Antibiotics.

Antibiotics inhibit essential bacterial processes, resulting in arrest of growth and, in some cases, cell death. Many antibiotics are also reported to trigger endogenous production of reactive oxygen species (ROS), which damage DNA, leading to induction of the mutagenic SOS response associated with the emergence of drug resistance. However, the type of DNA damage that arises and how this triggers the SOS response are largely unclear. We found that several different classes of antibiotic triggered dose-dependent induction of the SOS response in Staphylococcus aureus, indicative of DNA damage, including some bacteriostatic drugs. The SOS response was heterogenous and varied in magnitude between strains and antibiotics. However, in many cases, full induction of the SOS response was dependent upon the RexAB helicase/nuclease complex, which processes DNA double-strand breaks to produce single-stranded DNA and facilitate RecA nucleoprotein filament formation. The importance of RexAB in repair of DNA was confirmed by measuring bacterial survival during antibiotic exposure, with most drugs having significantly greater bactericidal activity against rexB mutants than against wild-type strains. For some, but not all, antibiotics there was no difference in bactericidal activity between wild type and rexB mutant under anaerobic conditions, indicative of a role for reactive oxygen species in mediating DNA damage. Taken together, this work confirms previous observations that several classes of antibiotics cause DNA damage in S. aureus and extends them by showing that processing of DNA double-strand breaks by RexAB is a major trigger of the mutagenic SOS response and promotes bacterial survival.

When Is Enough Enough? Orgasm's Curvilinear Association With Relational and Sexual Satisfaction.

BACKGROUND: Curvilinearity has been found for sexual frequency, but research has not examined whether curvilinear associations exist for other aspects of sexual relationships like orgasm consistency. AIM: We examined whether there is curvilinearity and the nature of that curvilinearity between orgasm consistency and sexual and relational satisfaction for men and women. METHODS: With pooled samples of 1,619 and 1,695 men and women from Amazon's Mechanical Turk, we examined the differences of orgasm consistency values and both sexual satisfaction and relationship satisfaction through analysis of variance. We then tested for curvilinearity between orgasm consistency and sexual and relational satisfaction with regression analyses. OUTCOMES: For men we found no evidence of a curvilinear relationship, but for women we found a curvilinear relationship between orgasm consistency values and both sexual satisfaction and relationship satisfaction. RESULTS: Across tests, the overall picture suggests that there is no curvilinear association for men, but there is for women. For women, with each unit increase in orgasm consistency, the increase in sexual satisfaction and relationship satisfaction became progressively smaller. Past the 61-80% threshold for orgasm consistency, there was little gain in sexual satisfaction and no gain in relational satisfaction. CLINICAL TRANSLATION: Physicians, therapists, and educators can reorient women's orgasm expectations by explaining that having regular orgasms-not necessarily always-is associated with satisfaction in their relationship and sexual experience. STRENGTHS & LIMITATIONS: Converging large samples and data analytic techniques evinced the curvilinear association between orgasm consistency and both relational and sexual satisfaction for women. However, this study is cross-sectional and correlational, which limits the conclusions we can draw from it. CONCLUSION: While men's orgasm consistency is linearly associated with relational and sexual satisfaction, more consistent orgasms seem to be associated with women's sexual and relational satisfaction, to a point.

Outdoor light at night and breast cancer incidence in the Danish Nurse Cohort.

BACKGROUND: Knowledge of the role of melatonin, xenograft experiments, and epidemiological studies suggests that exposure to light at night (LAN) may disturb circadian rhythms, possibly increasing the risk of developing breast cancer. OBJECTIVES: We examined the association between residential outdoor LAN and the incidence of breast cancer: overall and subtypes classified by estrogen (ER) and progesterone (PR) receptor status. METHODS: We used data on 16,941 nurses from the Danish Nurse Cohort who were followed-up from the cohort baseline in 1993 or 1999 through 2012 in the Danish Cancer Registry for breast cancer incidence and the Danish Breast Cancer Cooperative Group for breast cancer ER and PR status. LAN exposure data were obtained from the U.S. Defense Meteorological Satellite Program (DMSP) available for 1996, 1999, 2000, 2003, 2004, 2006, and 2010 in nW/cm2/sr unit, and assigned to the study participants' residence addresses during the follow-up. Time-varying Cox regression models were used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between LAN and breast cancer, adjusting for individual characteristics, road traffic noise, and air pollution. RESULTS: Of 16,941 nurses, 745 developed breast cancer in total during 320,289 person-years of follow-up. We found no association between exposure to LAN and overall breast cancer. In the fully adjusted models, HRs for the highest (65.8-446.4 nW/cm2/sr) and medium (22.0-65.7 nW/cm2/sr) LAN tertiles were 0.97 (95% CI: 0.77, 1.23) and 1.09 (95% CI: 0.90, 1.31), respectively, compared to the lowest tertile of LAN exposure (0-21.9 nW/cm2/sr). We found a suggestive association between LAN and ER-breast cancer. CONCLUSION: This large cohort study of Danish female nurses suggests weak evidence of the association between LAN and breast cancer incidence.

Linking Sexual Mindfulness to Mixed-Sex Couples' Relational Flourishing, Sexual Harmony, and Orgasm.

Marriage is an important adult relationship, and recent research indicates that sexual mindfulness, awareness and non-judgment, may be an important tool in helping maintain relational and sexual well-being. Using a nationally representative U.S. sample of newly married, mixed-sex couples (women's age M = 29.70 years; men's age M = 31.76 years; N = 1473 couples), we evaluated whether the two factors of sexual mindfulness, awareness and non-judgment, were linked with relational flourishing, sexual harmony, and orgasm consistency. We utilized an actor-partner interdependence model within a structural equation modeling framework to evaluate how husbands' and wives' awareness and non-judgment were associated with relational flourishing, sexual harmony, and orgasm consistency. Results indicated that both wives' and husbands' awareness was positively associated with relational flourishing, sexual harmony, and orgasm consistency. Partner effects were found for all outcomes. However, no partner effects were found between non-judgment and orgasm consistency. Therapists, educators, and couples may consider the use of sexual mindfulness skills when addressing marriage and sexual relationships.

The influence of marital status and partner concordance on participation in colorectal cancer screening.

BACKGROUND: Colorectal cancer screening program using a fecal immunochemical test aims to reduce morbidity and mortality through early detection. Although screening participation is free-of-charge, almost 40% of the invited individuals choose not to participate. To bring new insight into how non-participation can be identified and targeted, we examined the association between marital status and screening participation; with a focus on partner concordance in participation and sex differences. METHODS: This nationwide cross-sectional study included all Danish citizens aged 50-74 years, who were invited to colorectal cancer screening between 2014 and 2017. Logistic regression analysis was used to estimate odds ratio (OR) of participation while adjusting for sociodemographic variables. RESULTS: A total of 1 909 662 individuals were included in the analysis of which 62.7% participated in the screening program. Participation was highest among women. Stratified by marital status, screening participation was markedly lower in widowed (61.5%), divorced (54.8%) and single (47.3%), while participation reached 68.4% in married individuals. This corresponded to ORs of 0.59 (95% CI 0.58-0.59) for widowed, 0.56 (95% CI 0.55-0.56) for divorced and 0.47 (95% CI 0.47-0.48) for single, compared to married individuals. Individuals married to a participating partner were five times more likely to participate than married individuals with a non-participating partner, regardless of gender. CONCLUSIONS: Marital status was strongly associated with participation in colorectal cancer screening, and participation was even higher in married individuals with a participating partner. Future efforts to increase participation in colorectal cancer screening could potentially benefit from considering the role of partner concordance.

Perspectives from Highly Religious Families on Boundaries and Rules About Sex.

We investigated the intersection of religion and boundaries placed around sex using qualitative data from 198 highly religious Muslim, Christian, and Jewish families. Coding performed by two researchers resulted in six core themes that provide insight into the connection between these two domains. Frequency counts of the core themes, participant quotes, and implications are presented-including the benefits of practitioners inquiring into how clients' faith affects sexual behavior and scripts, how fidelity and vows might serve a protective function for the relationships of highly religious couples, and how religion may empower women in terms of sexual boundary setting.

RexAB is essential for the mutagenic repair of Staphylococcus aureus DNA damage caused by co-trimoxazole.

Co-trimoxazole (SXT) is a combination therapeutic that consists of sulfamethoxazole and trimethoprim that is increasingly used to treat skin and soft-tissue infections caused by methicillin-resistant Staphylococcus aureus (MRSA). However, the use of SXT is limited to the treatment of low-burden, superficial S. aureus infections and its therapeutic value is compromised by the frequent emergence of resistance. As a first step towards the identification of approaches to enhance the efficacy of SXT, we examined the role of bacterial DNA repair in antibiotic susceptibility and mutagenesis. We found that mutants lacking the DNA repair complex RexAB had a modest 2-fold lower SXT MIC than wild-type strains but were killed 50-5000-fold more efficiently by the combination antibiotic at the breakpoint concentration. SXT-mediated DNA damage occurred via both thymidine limitation and the generation of reactive oxygen species, and triggered induction of the SOS response in a RexAB-dependent manner. SOS induction was associated with a 50% increase in the mutation rate, which may contribute to emergence of resistant strains during SXT therapy. In summary, this work determined that SXT caused DNA damage in S. aureus via both thymidine limitation and oxidative stress, which was repaired by the RexAB complex, leading to induction of the mutagenic SOS response. Small molecule inhibitors of RexAB could therefore have therapeutic value by increasing the efficacy of SXT and decreasing the emergence of drug-resistance during treatment of infections caused by S. aureus.
