Socioeconomic changes predict genome-wide DNA methylation in childhood.

Childhood socioeconomic position (SEP) is a major determinant of health and well-being across the entire life course. To effectively prevent and reduce health risks related to SEP, it is critical to better understand when and under what circumstances socioeconomic adversity shapes biological processes. DNA methylation (DNAm) is one such mechanism for how early life adversity 'gets under the skin'. In this study, we evaluated the dynamic relationship between SEP and DNAm across childhood using data from 946 mother-child pairs in the Avon Longitudinal Study of Parents and Children. We assessed six SEP indicators spanning financial, occupational and residential domains during very early childhood (ages 0-2), early childhood (ages 3-5) and middle childhood (ages 6-7). Epigenome-wide DNAm was measured at 412 956 cytosine-guanines (CpGs) from peripheral blood at age 7. Using an innovative two-stage structured life-course modeling approach, we tested three life-course hypotheses for how SEP shapes DNAm profiles-accumulation, sensitive period and mobility. We showed that changes in the socioeconomic environment were associated with the greatest differences in DNAm, and that middle childhood may be a potential sensitive period when socioeconomic instability is especially important in shaping DNAm. Top SEP-related DNAm CpGs were overrepresented in genes involved in pathways important for neural development, immune function and metabolic processes. Our findings highlight the importance of socioeconomic stability during childhood and if replicated, may emphasize the need for public programs to help children and families experiencing socioeconomic instability and other forms of socioeconomic adversity.

Depressive symptoms in adolescence and adult educational and employment outcomes: a structured life course analysis.

BACKGROUND: Depression is a common mental health disorder that often starts during adolescence, with potentially important future consequences including 'Not in Education, Employment or Training' (NEET) status. METHODS: We took a structured life course modeling approach to examine how depressive symptoms during adolescence might be associated with later NEET status, using a high-quality longitudinal data resource. We considered four plausible life course models: (1) an early adolescent sensitive period model where depressive symptoms in early adolescence are more associated with later NEET status relative to exposure at other stages; (2) a mid adolescent sensitive period model where depressive symptoms during the transition from compulsory education to adult life might be more deleterious regarding NEET status; (3) a late adolescent sensitive period model, meaning that depressive symptoms around the time when most adults have completed their education and started their careers are the most strongly associated with NEET status; and (4) an accumulation of risk model which highlights the importance of chronicity of symptoms. RESULTS: Our analysis sample included participants with full information on NEET status (N = 3951), and the results supported the accumulation of risk model, showing that the odds of NEET increase by 1.015 (95% CI 1.012-1.019) for an increase of 1 unit in depression at any age between 11 and 24 years. CONCLUSIONS: Given the adverse implications of NEET status, our results emphasize the importance of supporting mental health during adolescence and early adulthood, as well as considering specific needs of young people with re-occurring depressed mood.

Implementation of a Nurse-Driven Eat-Sleep-Console (ESC) Treatment Pathway at a Community Hospital for Treatment of Neonatal Opioid Withdrawal Syndrome in an Effort to Improve Short-term Outcomes.

BACKGROUND: The Chandler Regional Medical Center (CRMC) neonatal intensive care unit (NICU) began a phased implementation of Eat-Sleep-Console (ESC) for the management of those at risk for neonatal opioid withdrawal syndrome (NOWS). PURPOSE: The purpose of this initiative is to track short-term outcomes as well as the program's effect on nursing workflow and job performance rating/satisfaction. METHODS: A retrospective review of the ESC implementation process at CRMC from the years 2018-2020. The study consisted of 3 epochs: (1) traditional pharmacologic management; (2) parent-led ESC management; and (3) parent/nurse-led ESC management. Length of stay (LOS), treatment pathway assignment, and proportion of infants treated with pharmacologic agents were compared between epochs. In addition, a survey of NICU nursing staff was distributed to measure nurses' perceptions and attitudes towards the ESC program and the management of infants with NOWS. RESULTS: The proportion of infants treated via ESC increased (0%, 53%, and 100%), with an associated decrease in LOS (18.4, 10.5, and 9.3 days) during each epoch of the study period. Thirty-seven nurses completed the survey, with 94% of nurses reporting being comfortable caring for ESC patients and 89% feeling supported in their ESC nursing assignments, with only 11% stating that caring for ESC patients significantly alters their other nursing care processes. IMPLICATIONS FOR PRACTICE AND RESEARCH: Implementation of an ESC treatment program for infants with NOWS significantly decreased LOS and the proportion of infants treated pharmacologically. This phased implementation process was not associated with self-reported negative nursing perceptions of the program and its treatment goals/outcomes.

Observational Behavioral Coding in the Pediatric Emergency Department: Development of the Emergency Department Child Behavior Coding System.

BACKGROUND: Despite improvements over the past decade, children continue to experience significant pain and distress surrounding invasive procedures in the emergency department (ED). To assess the impact of newly developed interventions, we must create more reliable and valid behavioral assessment tools that have been validated for the unique settings of pediatric EDs. OBJECTIVE: This study aimed to create and test the Emergency Department Child Behavior Coding System (ED-CBCS) for the assessment of child distress and nondistress behaviors surrounding pediatric ED procedures. METHODS: Via an iterative process, a multidisciplinary expert panel developed the ED-CBCS, an advanced time-based behavioral coding measure. Inter-rater reliability and concurrent validity were examined using 38 videos of children aged from 2 to 12 years undergoing laceration procedures. Face, Legs, Activity, Cry, Consolability (FLACC) scale scores were used to examine concurrent validity. RESULTS: The final ED-CBCS included 27 child distress and nondistress behaviors. Time-unit κ values from 0.64 to 0.98 and event alignment κ values from 0.62 to 1.00 indicated good to excellent inter-rater reliability for all but one of the individual codes. ED-CBCS distress (B = 1.26; p < 0.001) and nondistress behaviors (B = -0.69, p = 0.025) were independently significantly associated with FLACC scores, indicating concurrent validity. CONCLUSIONS: We developed a psychometrically sound tool tailored for pediatric ED procedures. Future work could use this measure to better identify behavioral targets and test the effects of interventions to relieve pediatric ED pain and distress.

Testing lifecourse theories characterising associations between maternal depression and offspring depression in emerging adulthood: the Avon Longitudinal Study of Parents and Children.

BACKGROUND: Maternal depression is a major determinant of offspring mental health. Yet, little is understood about how the duration and timing of maternal depression shapes youth risk for depressive symptoms, which if understood could inform when best to intervene. This study aimed to determine how the timing and duration of maternal depression was related to offspring depression in emerging adulthood, and if these associations varied by sex. METHODS: We analysed data from the Avon Longitudinal Study of Parents and Children (a prenatal cohort in the Avon area of England, 1991-2003), n = 3,301. We applied the structured lifecourse modelling approach to maternal depression (assessed at 13 points from prenatal period to adolescence) and emerging adult depressive symptoms (age 21). Lifecourse models assessed were accumulation (sum of timepoints when maternal depression was reported), sensitive periods (each period assessed as one during which maternal depression has a stronger effect) and instability (frequent fluctuations in maternal depression). RESULTS: Female adolescents (n = 2,132) had higher SMFQ scores (mean = 6.15, SD = 5.90) than males (n = 1,169, mean = 4.87, SD = 4.82). Maternal depression was most common in the infancy period (21.2% males; 21.4% females). For males, accumulation was the most appropriate lifecourse model; for each additional period of maternal depression, depressive symptoms in emerging adulthood increased by 0.11 (95% CI: 0.07, 0.15, one-sided p value ≤ .001). For females, exposure to maternal depression was associated with increasing depressive symptoms in emerging adulthood, with the largest effect in mid-childhood (increase of 0.27 units, 95% CI 0.03-0.50, p = .015 for difference between mid-childhood and other time-periods) and a smaller, equal effect at all other time-periods (increase of 0.07 units per time-period, 95% CI: 0.03-0.12, p = .002). CONCLUSIONS: This study highlights the importance of ongoing maternal depression for the development of depression in offspring through to emerging adulthood. Because long-term exposure to maternal depression was particularly important, early interventions are warranted.

The Impact of Digital Mental Health Services on Loneliness and Mental Health: Results from a Prospective, Observational Study.

BACKGROUND: Loneliness has increased since the COVID-19 pandemic and negatively impacts mental health. This study examined relationships between loneliness and mental health among adults using a digital mental health platform. METHODS: A purposive sample of 919 participants (97% response rate) who were newly enrolled in the platform completed a survey on loneliness, depression, anxiety, well-being, stress, social support, and comorbidities at baseline and 3 months. Platform engagement was tracked during this period. We examined baseline differences between lonely and non-lonely participants; associations between loneliness, mental health symptoms, and comorbidities; and changes in loneliness and mental health through engagement in any form of care. RESULTS: At baseline, 57.8% of the sample were categorized as lonely. Loneliness was associated with younger age, fewer years of education, and the presence of a comorbidity (p values < .05). Baseline loneliness was associated with greater depression, anxiety, and stress and lower well-being and social support (ps < .001). The percentage of lonely participants decreased at follow-up (57.6% to 52.9%, p = .03). Those who improved in loneliness improved in mental health symptoms, well-being, and social support (ps < .001). Lonely participants who engaged in any form of care reported a greater reduction in loneliness than those who did not engage (p = .04). CONCLUSIONS: This study confirms previous findings of the high prevalence of loneliness among adults and risk factors for increased loneliness. Findings highlight the potential of digital platforms to reach lonely individuals and alleviate loneliness through remote mental health support.

Alcohol Use Disorder Symptoms Reported during Midlife: Results from the Monitoring the Future Study among US Adults at Modal Ages 50, 55, and 60.

BACKGROUND: The extent to which adolescent substance use is associated with alcohol use disorder (AUD) symptoms in midlife is not yet fully explored. METHODS: Longitudinal data from the national Monitoring the Future study was used. The sample included 11,830 12th graders (1976-1987) who were surveyed again at modal ages 50 (37.8%), 55 (46.3%), or 60 (15.8%) in 2008-2019. Approximately 48.7% were male; 81.5% identified as non-Hispanic White. Weighted logistic and multinomial logistic regressions were used to examine associations between past 30-day use of cigarettes, marijuana, and alcohol at age 18, sociodemographics, and a midlife AUD symptom outcome (coded as non-drinking, drinking without AUD [endorsed ≤1 criterion], or AUD symptoms [endorsed 2+ criteria]). RESULTS: Prevalence of midlife AUD symptoms was 27.1%. Higher relative risk of reporting AUD symptoms (vs. drinking without AUD) was associated with age 18 substance use (any cigarette use [vs. no use], any marijuana use [vs. no use], binge drinking [vs. both no use and drinking at less than binge levels]), being male (vs. female), being non-Hispanic White (vs. non-Hispanic Black), and having a 4-year college degree. Higher relative risk of reporting non-drinking (vs. drinking without AUD) was associated with no 30-day alcohol use at age 18, being non-Hispanic Black or non-Hispanic other (vs. non-Hispanic White), and not having a 4-year college degree. CONCLUSIONS: Findings suggest substance use at age 18 has meaningful associations with midlife AUD symptoms. Dissemination of prevention and intervention efforts in adolescence and early adulthood may be important for reducing hazardous midlife drinking.

Prognostication in post-stroke aphasia: Perspectives of people with aphasia on receiving information about recovery.

Many people with aphasia (language impairment post-stroke) want to know their prognosis for recovery, yet current understanding of their experience of receiving prognoses is limited. Such insight is necessary to inform clinical practice in formulating and delivering aphasia prognoses, especially given the psycho-emotional distress and secondary adverse effects on recovery associated with conversations about prognosis. We sought an in-depth understanding of the perspectives of people with aphasia in relation to receiving prognoses post-stroke, with the aim of informing an evidence-based approach to aphasia prognostication in clinical practice. Semi-structured interviews, facilitated by communication support strategies, were conducted one-to-one with eight people with aphasia (ranging from mild to very severe) 3-12 months post-stroke. Reflexive thematic analysis was used to analyse the qualitative data, yielding two over-arching themes: (1) How would you know without knowing me?; (2) I need to know, but I don't want to know. Our findings illustrate issues of mistrust within the patient-clinician relationship, and complex emotions relating to hope and post-stroke adjustment. The present insight into the lived experience of receiving aphasia prognoses highlights the need for focused consideration of personal definitions of normalcy, measures for fostering trust, and the role of prognostic uncertainty.

Brain-associated innate leukocytes display diverse inflammatory states following experimental stroke.

Previous studies investigating innate leukocyte recruitment into the brain after cerebral ischemia have shown conflicting results. Using distinct cell surface and intracellular markers, the current study evaluated the contributions of innate immune cells to the poststroke brain following 1-h middle cerebral artery occlusion (tMCAO) or permanent MCAO (pMCAO), and assessed whether these cells ascribed to an inflammatory state. Moreover, we examined whether there is evidence for leukocyte infiltration into the contralateral (CL) hemisphere despite the absence of stroke infarct. We observed the recruitment of peripheral neutrophils, monocytes and macrophages into the hemisphere ipsilateral (IL) to the ischemic brain infarct at 24 and 96 h following both tMCAO and pMCAO. In addition, we found evidence of increased leukocyte recruitment to the CL hemisphere but to a lesser extent than the IL hemisphere after stroke. Robust production of intracellular cytokines in the innate immune cell types examined was most evident at 24 h after pMCAO. Specifically, brain-associated neutrophils, monocytes and macrophages demonstrated stroke-induced production of tumor necrosis factor-α (TNF-α) and interleukin (IL)-1ß, while only monocytes and macrophages exhibit a significant expression of arginase 1 (Arg1) after stroke. At 96 h after stroke, brain-resident microglia demonstrated production of TNF-α and IL-1ß following both tMCAO and pMCAO. At this later timepoint, neutrophils displayed TNF-α production and brain-associated macrophages exhibited elevation of IL-1ß and Arg1 after tMCAO. Further, pMCAO induced significant expression of Arg1 and IL-1ß in monocytes and macrophages at 96 h, respectively. These results revealed that brain-associated innate immune cells display various stroke-induced inflammatory states that are dependent on the experimental stroke setting.

MRSA nasal swab PCR to de-escalate antibiotics in the emergency department.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) nasal swab polymerase chain reaction (PCR) assay has a 96.1-99.2% negative predictive value (NPV) in pneumonia and may be used for early de-escalation of MRSA-active antibiotic agents. Xu (2018), File (2010) [1,2]. OBJECTIVE: The objective of our study was to determine if a negative MRSA PCR nasal swab collected in the emergency department (ED) improves early MRSA-active antibiotic de-escalation. METHODS: A single center observational cohort study used ICD-10 codes to identify records for adults admitted to the ED with a hospital discharge diagnosis of pneumonia. The primary outcome was proportion of patients with early de-escalation on an MRSA-active agent (≤ 1 dose). Secondary outcomes included rate of acute kidney injury (AKI), positive MRSA cultures (blood culture, respiratory sputum, tracheal aspirate), hospital length of stay (LOS), in-hospital mortality, and 30-day readmission rates. RESULTS: A total of 341 patients were included in the study. Of the patients with an MRSA PCR swab, 35.2% of patients with a negative swab received >1 dose of MRSA-active agent compared to 52% of patients without an MRSA nasal swab (p < 0.01). There were no significant differences in secondary outcomes except readmission rate of 1.6% of patients that did not have an MRSA swab in the ED vs 6.6% of patients that received an MRSA swab in the ED. CONCLUSION AND RELEVANCE: MRSA PCR nasal swabs in the ED may serve as a useful tool for early MRSA-active antibiotic de-escalation when treating pneumonia.

Dynamic roles of neutrophils in post-stroke neuroinflammation.

Clinical trials involving the blockage of peripheral inflammatory leukocyte recruitment into the brain have puzzlingly led to either no significant improvement in stroke outcome, or even worsened outcomes and increased mortality, prompting a re-evaluation of our understanding into the neuroinflammatory processes after stroke. Whilst traditionally understood as simple effectors of the innate immune system, emerging research in vascular disease biology has redefined the neutrophil as a specialized and highly specific cell type with dynamic functional capacity. Indeed, emerging experimental evidence indicates that neutrophils display diverse roles in the acute stages of ischemic stroke with the ability to elicit both pro-inflammatory and anti-inflammatory effects. Currently, there is some uncertainty as to whether neutrophil diversity is beneficial or harmful in stroke as their interactions with the resident cells of the brain, such as microglia and neurons, would potentially elicit heterogeneous outcomes. Current treatments for patients with stroke aim to remove the vascular blockage and to restore blood flow, but there are currently no drug treatments for managing the loss of functional brain tissue nor restoration of microglial and neuronal damage. If these hypothesized wound-healing functions of neutrophils can be validated in a stroke setting, promoting the recruitment of this type of neutrophils into the injured brain tissue may form a promising therapeutic target for the majority of stroke patients currently without treatment. In this review, we will provide an update on recent research that has explored neutrophil heterogeneity in the neuroinflammatory cascade after ischemic stroke.

Latent profile analysis of interpersonal problems: Attachment, basic psychological need frustration, and psychological outcomes.

The purpose of this project was to identify distinct profiles of circumplex interpersonal problems, cross-validate the profiles, and examine construct validity through associations with adult attachment, basic psychological needs frustration, and psychological outcomes. Undergraduates at two universities provided survey data. In Study 1 (N = 469), latent profile analysis identified three distinct profiles of interpersonal problems. We labeled these: Flexible-Adaptive, Exploitable-Subservient, and Hostile-Avoidant. Construct validity analyses suggested the Flexible-Adaptive profile was distinguished from the other two by lower attachment anxiety, whereas the Hostile-Avoidant profile was distinguished from the other two by higher attachment avoidance. In Study 2 (N = 423), we conducted profile similarity analyses to cross-validate Study 1 results, following the multistep procedure proposed by Morin et al. (Organizational Research Methods, 2016, 19, p. 231). Results suggested that when the data from Study 2 were constrained to fit the profile model derived from Study 1, with respect to means, variance, and latent profile membership, the model fit was equivalent. In Study 2, further evidence of construct validity suggested that the Flexible-Adaptive profile was distinguished from the other two by lower relatedness frustration and by lower competence frustration. Additionally, the Hostile-Avoidant profile was distinguished from the Exploitable-Subservient profile by higher relatedness need frustration. Validity evidence for these profiles indicated that those with the Hostile-Avoidant profile reported the most negative psychological outcomes, followed by those with the Exploitable-Subservient profile, while those with the Flexible-Adaptive profile reported the best psychological outcomes.

Alcohol and cannabis motives: Differences in daily motive endorsement on alcohol, cannabis, and alcohol/cannabis co-use days in a cannabis-using sample.

OBJECTIVE: Same day use of alcohol and cannabis is prevalent among emerging/young adults and increases the risk for negative consequences. Although motives for alcohol and cannabis use are well-documented, specific motives on co-use days are under-investigated. We examined differences in motives on single substance use (i.e., alcohol or cannabis) versus co-use days in a sample of primarily cannabis-using emerging/young adults. METHODS: Participants (N=97) aged 18-25 (Mage=22.2) were recruited from an urban Emergency Department (55.7% female, 46.4% African American, 57.7% public assistance) for a prospective daily diary study about risk behaviors. Participants received prompts for 28 daily text message assessments (up to 2716 surveys possible) of substance use and motives (social, enhancement, coping, conformity). We divided use days into three groups: alcohol use only (n=126), cannabis use only (n=805), and co-use (n=237). Using fixed effects regression modeling, we fit models to estimate within-person effects of alcohol and cannabis motives on day type (alcohol/cannabis co-use versus single use). RESULTS: In adjusted models, greater cannabis-related enhancement and social motives were associated with increased likelihood of co-use days compared to cannabis-only days. In contrast, greater alcohol-related social motives were associated with co-use days versus alcohol-only days in unadjusted, but not in adjusted models. CONCLUSIONS: Findings suggest that cannabis use motives associated with increasing positive affect may be most compelling for those engaging in alcohol/cannabis use on a given day. Intervention programs for alcohol/cannabis use should address alcohol and cannabis use motives in relation to increasing positive affect and engaging in social situations.

Myocardial fibrosis, inflammation, and altered cardiac gene expression profiles in rats exposed to a predator-based model of posttraumatic stress disorder.

People who are exposed to life-threatening trauma are at risk of developing posttraumatic stress disorder (PTSD). In addition to psychological manifestations, PTSD is associated with an increased risk of myocardial infarction, arrhythmias, hypertension, and other cardiovascular problems. We previously reported that rats exposed to a predator-based model of PTSD develop myocardial hypersensitivity to ischemic injury. This study characterized cardiac changes in histology and gene expression in rats exposed this model. Male rats were subjected to two cat exposures (separated by a period of 10 d) and daily cage-mate changes for 31 d. Control rats were not exposed to the cat or cage-mate changes. Ventricular tissue was analyzed by RNA sequencing, western blotting, histology, and immunohistochemistry. Multifocal lesions characterized by necrosis, mononuclear cell infiltration, and collagen deposition were observed in hearts from all stressed rats but none of the control rats. Gene expression analysis identified clusters of upregulated genes associated with endothelial to mesenchymal transition, endothelial migration, mesenchyme differentiation, and extracellular matrix remodeling in hearts from stressed rats. Consistent with endothelial to mesenchymal transition, rats from stressed hearts exhibited increased expression of α-smooth muscle actin (a myofibroblast marker) and a decrease in the number of CD31 positive endothelial cells. These data provide evidence that predator-based stress induces myocardial lesions and reprograming of cardiac gene expression. These changes may underlie the myocardial hypersensitivity to ischemia observed in these animals. This rat model may provide a useful tool for investigating the cardiac impact of PTSD and other forms of chronic psychological stress.Lay summaryChronic predator stress induces the formation of myocardial lesions characterized by necrosis, collagen deposition, and mononuclear cell infiltration. This is accompanied by changes in gene expression and histology that are indicative of cardiac remodeling. These changes may underlie the increased risk of arrhythmias, myocardial infarction, and other cardiac pathologies in people who have PTSD or other forms of chronic stress.

Swim bladder enhances lagenar sensitivity to sound pressure and higher frequencies in female plainfin midshipman (Porichthys notatus).

The plainfin midshipman fish (Porichthys notatus) is an established model for investigating acoustic communication because the reproductive success of this species is dependent on the production and reception of social acoustic signals. Previous work showed that female midshipman have swim bladders with rostral horn-like extensions that project close to the saccule and lagena, while nesting (type I) males lack such rostral swim bladder extensions. The relative close proximity of the swim bladder to the lagena should increase auditory sensitivity to sound pressure and higher frequencies. Here, we test the hypothesis that the swim bladder of female midshipman enhances lagenar sensitivity to sound pressure and higher frequencies. Evoked potentials were recorded from auditory hair cell receptors in the lagena in reproductive females with intact (control condition) and removed (treated condition) swim bladders while pure tone stimuli (85-1005 Hz) were presented by an underwater speaker. Females with intact swim bladders had auditory thresholds 3-6 dB lower than females without swim bladders over a range of frequencies from 85 to 405 Hz. At frequencies from 545 to 1005 Hz, only females with intact swim bladders had measurable auditory thresholds (150-153 dB re. 1 µPa). The higher percentage of evoked lagenar potentials recorded in control females at frequencies >505 Hz indicates that the swim bladder extends the bandwidth of detectable frequencies. These findings reveal that the swim bladders in female midshipman can enhance lagenar sensitivity to sound pressure and higher frequencies, which may be important for the detection of behaviorally relevant social signals.

How Do Audiologists Respond to Emotional and Psychological Concerns Raised in the Audiology Setting? Three Case Vignettes.

OBJECTIVES: Emotional and psychological well-being are essential to overall health, but there is little research showing how to approach emotional and psychological concerns in the audiological setting. This study investigated audiologists' self-reported clinical behaviors in response to emotional and psychological concerns and/or symptoms raised by audiology clients. DESIGN: A sample of 83 Australia-based audiologists completed a survey including vignettes presenting older adults with hearing loss and experiencing symptoms consistent with either depression or grief. Content analysis was used to explore: (1) audiologists' self-reported usual response when clients present with emotional and psychological concerns and/or symptoms in the audiological setting; (2) audiologists' ability to identify and describe psychological symptoms; and (3) audiologists' self-reported clinical behaviors relating to client referral for psychological support. RESULTS: When asked to describe their usual clinical course of action in response to the vignettes, over one half the audiologists described actions that address the clients concerns related to psychological well-being. Where audiologists described how they would provide psychological support, they described modifications to the audiological rehabilitation program including involving significant others in the rehabilitation process, recommending additional support outside of the audiology setting (such as General Practitioner or psychologists), and providing emotional support and counseling. When prompted, the majority of participants recognized the two cases with depression as having a mental health condition; however, 48% of participants indicated the control case as also having a mental health condition. When asked directly, the majority of audiologists indicated that they would refer the three vignettes for specialist support; however, less than one third described referral to a General Practitioner and less than 5% described referral to a mental health professional as their normal course of action in the open response item. Twenty-five different professions/people were reported as potential sources for referral. CONCLUSION: These findings support the need for further training and/or resources for audiologists to enable them to appropriately detect, describe and refer for emotional and psychological concerns and/or symptoms raised by clients' in the audiology setting.

Breeder-reported patterns of antimicrobial use and point prevalence of methicillin-resistant Staphylococcus spp. among breeding bitches in the southwestern United States.

Methicillin-resistant Staphylococcus pseudintermedius skin infections are an increasing concern in veterinary medicine, especially when found in juvenile dogs with no prior antimicrobial exposure. The objectives of this study were to assess the prevalence of methicillin-resistant staphylococci in breeding bitches and survey antimicrobial administration by their breeders. A total of 17 breeders and 54 bitches were included. Bitches were housed in diverse environments throughout the Phoenix, Arizona, USA metropolitan region. Nasal and oral gingival swabs were submitted for selective culture. Methicillin-resistant Staphylococcus aureus was not present, while methicillin-resistant Staphylococcus pseudintermedius was found in only 1/54 (1.9%) dogs. Survey results revealed that 16 bitches, which did not include the 1 MRSP-positive dog, had received antimicrobials within 6 months prior to sampling. Regardless of the low point prevalence identified, veterinarians and breeders should be cognizant of risks for bacterial resistance with the overuse of antimicrobials.

Patron d'utilisation des antimicrobiens rapporté par les éleveurs et prévalence ponctuelle de Staphylococcus spp. résistant à la méthicilline parmi des chiennes de reproduction dans le Sud-Ouest des États-Unis. Les infections cutanées dues à Staphylococcus pseudintermedius résistant à la méthicilline sont une préoccupation grandissante en médecine vétérinaire, surtout lorsque retrouvée chez des chiens juvéniles sans exposition préalable aux antibiotiques. Les objectifs de la présente étude étaient d'évaluer la prévalence de staphylocoques résistants à la méthicilline chez des chiennes reproductrices et sonder l'administration d'antimicrobiens par les éleveurs. Un total de 17 éleveurs et de 54 chiennes furent inclus. Les chiennes étaient logées dans divers environnements de la région métropolitaine de Phoenix, Arizona, USA. Des écouvillons du nez et des gencives orales furent soumis pour une culture sélective. Aucun Staphylococcus aureus résistant à la méthicilline ne fut détecté, alors que S. pseudintermedius fut trouvé chez seulement 1/54 chiens (1,9 %). Les résultats du sondage ont révélé que 16 chiennes, qui n'incluaient pas la chienne positive pour MRSP, avaient reçu des antimicrobiens à l'intérieur des 6 mois précédant l'échantillonnage. Indépendamment de la faible prévalence ponctuelle identifiée, les vétérinaires et les éleveurs devraient être au fait des risques pour la résistance bactérienne associée avec la surutilisation des antimicrobiens.(Traduit par Dr Serge Messier).

Evaluation of the Dualistic Model of Passion for Alcohol Consumption among Emerging Adults Engaged in Risky Drinking.

Understanding factors influencing risky drinking among emerging adults could enhance interventions to reduce adverse outcomes. As a motivational construct, the dualistic model of passion (i.e., obsessive passion: drinking is compelling and conflicts with other life activities/values; harmonious passion: drinking is an important, but not overwhelming, part of life) offers a novel explanation for persistent alcohol use. Yet, the dualistic model of passion has not yet been evaluated in this at-risk population. Therefore, we examined whether the variables proposed by the dualistic model of passion were associated with sex, binge-drinking, and alcohol-related consequences among young risky drinkers. We analyzed cross-sectional baseline data collected as part of an ongoing randomized controlled trial of emerging adults (n=327; M age=22.6, SD=1.1, range 21-24; 61% female; 76% White non-Hispanic) engaged in risky drinking (AUDIT-C score ≥ 4 females, ≥ 5 males) recruited nationally via social media advertisements. A path analysis revealed significant positive direct effects between obsessive passion and binge drinking and alcohol-related consequences, and significant negative direct effects between male sex and harmonious passion and binge drinking. There was also a positive direct effect between binge drinking and alcohol-related consequences. Male sex and obsessive passion were both indirectly related to alcohol-related consequences via binge drinking. Type of passion and male sex differentiates risky drinkers who binge drink and who experienced alcohol-related consequences. Future research should examine whether targeting obsessive passion reduces binge drinking and negative outcomes.

Lagenar potentials of the vocal plainfin midshipman fish, Porichthys notatus.

The plainfin midshipman fish (Porichthys notatus) is a species of marine teleost that produces acoustic signals that are important for mediating social behavior. The auditory sensitivity of the saccule is well established in this species, but the sensitivity and function of the midshipman's putative auditory lagena are unknown. Here, we characterize the auditory-evoked potentials from hair cells in the lagena of reproductive type I males to determine the frequency response and auditory sensitivity of the lagena to behaviorally relevant acoustic stimuli. Lagenar potentials were recorded from the caudal and medial region of the lagena, while acoustic stimuli were presented by an underwater speaker. Our results indicate that the midshipman lagena has a similar low-frequency sensitivity to that of the midshipman saccule based on sound pressure and acceleration (re: 1 µPa and 1 ms-2, respectively), but the thresholds of the lagena were higher across all frequencies tested. The relatively high auditory thresholds of the lagena may be important for encoding high levels of behaviorally relevant acoustic stimuli when close to  a sound source.
