Regulation Transcriptional of Antibiotic Resistance Genes (ARGs) in Bacteria Isolated from WWTP.

The incidence of antibiotics and transcriptional regulation of ARGs in isolated bacteria from wastewater needs to be explored. By HPLC, in samples of untreated wastewater, ampicillin (49.74 ± 5.70 µg/mL), chloramphenicol (0.60 ± 0.03 µg/mL), tylosin (72.95 ± 2.03 µg/mL), and oxytetracycline (0.22 ± 0.01 µg/mL) was determined. Through metagenomic analysis identified 58 bacterial species belonging to 9 phyla and at least 14 species have shown resistance to a variety of antibiotics. Twenty-two bacterial isolates were proved to be resistant to fifteen antibiotics of new generation and used in medical research to combat infectious diseases. Fourteen strains were shown to harbor plasmids in size ranges of 2-5 Kb, 6-10 Kb and plasmids with size greater than 10 Kb. By quantitative PCR it was possible to identify genes sul, qnr, cat1, aadA1, and sat-1 gene were shown to be present in gDNA samples from treated and untreated samples of wastewater and by relative expression analysis, differential expression of cat1, ermB, act, and tetA genes was demonstrated in strains that showed identity with Escherichia coli, Bacteroides fragilis, and Salmonella thyphi, and that were stressed with different concentrations of antibiotics. The presence of ARGs in untreated water samples, as well as in bacterial isolates, was indicative that in these habitats there are microorganisms that can resist ß-lactams, aminoglycosides, tetracyclines, sulfonamides, and quinolones.

Exploring pain experience and anxiety sensitivity among Latinx adults in a federally qualified health center.

The Latinx population is the largest minority group in the United States (U.S.) and is expected to continue to grow through at least 2050. Although there is growing recognition of the importance of pain among Latinx individuals, few studies have examined individualized psychological processes governing pain severity and disability in Latinx populations. One psychological factor that has shown promise in relation to pain experience specifically and clinical conditions more generally is anxiety sensitivity. The present investigation sought to (1) characterize the severity of pain among an unselected sample of adult Latinx individuals attending a Federally Qualified Health Center (FQHC); (2) evaluate the severity of anxiety sensitivity as a function of pain severity; and (3) test the potential explanatory relevance of anxiety sensitivity as an individual difference factor for pain intensity, pain disability, psychological inflexibility for emotional distress, and global life impairment. Participants included 406 adult Spanish-speaking Latinx persons (87.2% female; Mage = 40.26 years, SD = 11.20, and 98.3% used Spanish as their first language) who attended an FQHC in Houston, Texas. Analyses revealed that 62.6% of the sample had at least some pain, and 21.9% of the same had high intensity, moderate interference, or severe interference chronic pain. Further, results provided evidence for anxiety sensitivity as a function of pain grade, such that individuals with grade 2 (high-intensity pain), grade 3 (moderate pain interference), and grade 4 (severe pain interference) chronic pain reported significantly higher levels of anxiety sensitivity than those with grade 0 pain (no chronic pain). Additionally, after controlling for age, gender, marital status, years of education, years living in the U.S., and generalized anxiety, anxiety sensitivity significantly accounted for significant variance in pain intensity, inflexibility in relation to emotional distress, and life impairment. Overall, the current study builds upon what is currently understood about anxiety sensitivity among the Latinx population and uniquely extends past work by linking individual differences in this construct to clinically relevant aspects of pain experience and life impairment among adults attending FQHC's. Additional clinical attention should be focused on anxiety sensitivity to offset pain disparities among this established health disparities group.

Heart-Focused Anxiety Among Latinxs in Primary Care: Relations to Anxiety, Depression, Pain, and Functional Impairment.

There is a public health need to better characterize the individual-based differences that may be involved in the expression and maintenance of psychological and related health problems among Latinx individuals. One individual difference factor that may be relevant to the nexus of psychological and physical concerns is heart-focused anxiety. The current study sought to evaluate the potential explanatory relevance of heart-focused anxiety as an important individual difference factor for anxiety, depression, pain experience, and functional impairment. Participants included 158 Latinx adults (Mage = 39.26, SD = 13.19; 85.4% female) from a primary health clinic. Results indicated that heart-focused anxiety was significantly related to anxious arousal, pain intensity, pain disability, and functional impairment. However, no significant effects were evident for depressive symptoms. These data indicate that heart-focused anxiety may be an underrecognized cognitive factor relevant to better understanding anxiety and pain among Latinx adults in primary care.

Examining the indirect effect of posttraumatic stress symptoms via emotion dysregulation on alcohol misuse among trauma-exposed Latinx in primary care.

OBJECTIVES: Latinx individuals face substantial health disparities, particularly in the areas of mental health and substance use. Among Latinx in the U.S., alcohol is the most widely abused substance and is associated with a range of negative consequences. Among Latinx, limited past work has linked trauma exposure/symptoms to alcohol misuse, however not much is known regarding how trauma exposure/symptoms may impact alcohol misuse. One potential explanatory mechanism underlying associations of traumatic stress and problematic alcohol use is emotion dysregulation. The current study sought to examine the explanatory role of emotion dysregulation in the associations of traumatic stress symptoms with alcohol misuse among trauma-exposed Latinx. Alcohol misuse was operationalized by two outcomes: alcohol use severity and probable screen for hazardous drinking. METHOD: Latinx adults (N = 238) were recruited from a Federally Qualified Health Center. Participants were interviewed using the M.I.N.I. and then completed various self-report assessments (in Spanish). Structural equation modeling was used to evaluate models. RESULTS: Structural models fit the data well. These models evidenced statistically significant indirect effects of posttraumatic stress symptoms via emotion dysregulation on alcohol use severity and probable screen for hazardous drinking. DISCUSSION AND CONCLUSIONS: In a sample comprising primarily females, posttraumatic stress symptoms may contribute to alcohol misuse and hazardous drinking attributable to maladaptive emotion regulation. Use of interventions targeting emotion dysregulation in the context of trauma and hazardous alcohol use among Latinx in primary care may be warranted.

Pain and Alcohol Use among Latinos in Primary Care: Examining Rumination as an Explanatory Factor.

BACKGROUND: Alcohol is a widely abused substance among Latinos. Yet, little is known regarding factors underlying hazardous drinking in this population. Growing work has linked pain to hazardous drinking, although highly limited work has focused on Latinos. OBJECTIVES: The aim of the current study was to test rumination as an underlying mechanism explaining relations between pain severity and alcohol use among Latinos. METHODS: Data from 252 low-income Latino adults (Mage = 38.7 years, SD = 10.8; 86.1% female) attending a community-based primary health care clinic were available. Participants completed measures of pain, rumination, and alcohol use. Structural equation modeling was used to evaluate the indirect effect of pain severity via rumination on alcohol use. RESULTS: The model displayed good fit to the data. There was a statistically significant indirect effect of pain severity via rumination on alcohol use. Conclusions/Importance: The current findings suggest that rumination may underlie associations of pain and alcohol use among Latinos. Future work in primary care medical settings may benefit from targeting ruminative thinking among Latinos who are experiencing pain to address hazardous drinking.

Identifying the role of sociodemographic factors in major depressive disorder and suicidality among Spanish-speaking Latino patients in a federally qualified health center.

Rates of suicide and major depressive disorder (MDD) are currently at the highest point in the history of the United States (US). However, these rates are not distributed evenly among the population and Latinos show disproportionately high rates of both suicide and MDD. Yet, past research has infrequently explored factors related to suicide and MDD in primary care settings that serve as the major community portal for mental health among the Latino population. Thus, the current study investigated sociodemographic variables (marital status, nativity, education, employment, primary language, age, and gender) in terms of their relations with suicidal ideation, suicide risk, MDD, and MDD symptom severity among Latino primary care patients in a Federally Qualified Health Center (N = 634, M age = 39.46, SD = 11.46, 87.1% female). Results indicated that gender and Nativity were associated with suicidal ideation, older age was associated with suicide risk, and higher education and having a partner were negatively associated with MDD and depressive symptom severity. These results provide novel insight into the role of sociodemographic factors predicting suicide and MDD among Latinos in primary care, and suggest greater scientific and clinical attention can be focused on certain sociodemographic factors to offset mental health disparities among this group.

A Novel Integrated Cognitive-Behavioral Therapy for Anxiety and Medication Adherence Among Persons Living With HIV/AIDS.

Persons living with HIV/AIDS (PLHIV) are able to live full lifespans after infection, however, rates of anxiety disorders among this population are elevated compared to national samples. Importantly, these anxiety symptoms and disorders have a negative effect on medication adherence, quality of life and other psychological disorders, such as depression. In order to reduce the impact of anxiety among PLHIV, a six-session transdiagnostic CBT-based treatment manual for anxiety among PLHIV named the HIV/Anxiety Management-Reduction Treatment (HAMRT) was developed and implemented. The current manuscript discusses the content of this manual as well as results from three cases examining the impact of HAMRT. Results indicated that HAMRT was effective in reducing symptoms of anxiety, anxiety sensitivity, depression, and negative affect among our sample. Additionally, results indicated that HAMRT was effective in increasing HIV medication adherence as well as quality of life. Results are discussed in terms of the potential utility of an anxiety-reduction therapy program aimed at increasing medication adherence among PLHIV.

Emotion dysregulation as a mechanism linking anxiety and hazardous drinking among Latinos in primary care.

BACKGROUND AND OBJECTIVES: Research suggests that Latinos experience significantly more mental health and alcohol use problems than non-Latino whites. However, relatively little is known about the mechanisms underlying alcohol use in this population. One factor associated with excessive alcohol use in Latinos is anxiety. A potential explanatory mechanism for this relationship is emotion dysregulation, as emotion dysregulation in the context of anxiety may lead to alcohol use problems/disorders. The aim of the current study was to examine the indirect effect of anxiety, through emotion dysregulation, on drinking severity and probable hazardous drinking in Latinos. METHODS: Latino adults (N = 264) were recruited from a primary care health clinic as part of a larger ongoing study examining mental health among Latinos in primary care. Participants were interviewed using the MINI and then completed various self-report assessments (in Spanish). Structural equation modeling was used to evaluate model fit. RESULTS: Structural models fit the data well. Additionally, there were statistically significant indirect effects of anxiety via emotion dysregulation on drinking severity and probable screen for hazardous drinking. DISCUSSION AND CONCLUSIONS: Anxiety may contribute to alcohol use problems due to an overall tendency to engage in maladaptive attempts to regulate emotions. SCIENTIFIC SIGNIFICANCE: Targeting emotion dysregulation in the context of anxiety and hazardous alcohol use among Latinos may be one therapeutic strategy to reduce severity of alcohol use (and hazardous drinking). (Am J Addict 2017;26:615-622).

Exploring the Mechanism Underlying the Association Between Pain Intensity and Mental Health Among Latinos.

There is limited understanding of pain and its relationship to mental health in Latinos, and limited knowledge about the biobehavioral mechanisms that underlie pain-mental health interrelations. To address these gaps, the present investigation sought to address whether anxiety sensitivity explained relations between pain intensity and anxious arousal, depressive symptoms, social anxiety, and depressive and anxiety disorders among an economically disadvantaged Latino sample. Participants included 349 adult Latinos (88% women; Mage = 38.8) who attended a community-based primary health care. In the multiple mediation model, anxiety sensitivity physical concerns accounted for the association between pain intensity and anxious arousal symptoms, cognitive concerns accounted for the association between pain intensity and depressive symptoms, and social concerns accounted for the association between pain intensity and social anxiety symptoms. This is the first study to demonstrate the explanatory role of anxiety sensitivity in pain-affective associations among disadvantaged Latinos.

Synergistic effects of pain and alcohol use in relation to depressive and anxiety symptoms among Latinos in primary care.

Although past work has shown that alcohol use co-occurs with anxiety/depression among Latinos, little work has examined the variables that qualify such associations. The present investigation sought to address whether pain severity (i.e. pain intensity and/or pain-related disability, respectively) moderated relations between hazardous drinking and depressive/anxious arousal symptoms among an economically disadvantaged Latino sample recruited from a primary care medical setting. Participants included 253 adult Latinos (Mage = 38.5 years, SD = 10.8; 86.6% female) who attended a community-based primary care clinic. There was a significant interaction of hazardous drinking with pain intensity in relation to depressive symptoms and significant interactions of hazardous drinking and pain-related disability in relation to depressive and anxious arousal symptoms. Hazardous drinking was associated with more severe depressive/anxious arousal symptoms only when pain intensity/disability was high. This is the first study to demonstrate the moderating role of pain intensity and disability in associations between hazardous drinking and anxiety/depression among Latinos in a primary care medical setting.

Negative Affectivity and Problematic Alcohol Use Among Latinos in Primary Care: The Role of Emotion Dysregulation.

OBJECTIVE: Latinos are the largest and most rapidly growing racial/ethnic group in the United States. In Latino communities, alcohol is the most widely abused substance, yet there is little empirical understanding of the factors underlying problematic alcohol use among Latinos. The current study explored whether negative affectivity exerted an indirect effect via emotion dysregulation in relation to two alcohol-related outcomes. METHODS: Participants were 316 Latinos attending a community-based primary care facility (Mage = 39.3, SD = 11.3; 85.4% female; 95.3% first language Spanish), who completed a variety of self-report and interview measures. Mediation analyses evaluated the indirect effect of negative affectivity via emotion dysregulation on problematic drinking and symptoms of alcohol dependence. RESULTS: While there was no direct or total effect of negative affectivity on either alcohol-related outcome, negative affectivity was significantly associated with both problematic alcohol use and symptoms of dependence via emotion dysregulation. Effect sizes were in the medium range, K(2) = .09 and .10, respectively. Post-hoc multiple mediation analyses evaluated subfactors of emotion dysregulation as mediators of the negative affectivity-alcohol associations. These results suggested that difficulties engaging in goal-directed behavior might be particularly important in explaining the association between negative affectivity and problematic alcohol use/symptoms of dependence. Last, independent mediation analyses evaluated emotion dysregulation subfactors and found that limited access to effective emotion regulation strategies and difficulties engaging in goal-directed behavior were, independently, significant mediators for both outcomes. Nonacceptance of emotional responses may also mediate negative affectivity and problematic drinking. Surprisingly, impulse control difficulties was not a significant mediator in any model. CONCLUSIONS: These data provide novel insight that among Latinos in primary care, emotion dysregulation is a possible mechanism underlying the indirect relationship between negative affectivity and problematic alcohol use and symptoms of dependence. Results also highlight specific facets of emotion dysregulation as potential targets of intervention. Future research should be longitudinal in nature, be conducted among more representative samples, and utilize measures that will better assess the potential variability in these associations. Results of such work may inform the development of alcohol treatment interventions incorporating the use of adaptive emotion regulation among Latinos in primary care.

Suicide attempts in the absence of depression: Differences between broad cultural groups.

Suicide is one of the leading causes of death worldwide (WHO, 2021). Depression is a common precursor to suicide and suicidality; however, individuals' experience of depression and the meaning of suicide differs depending on one's cultural background (Colucci, 2013; Goodmann et al., 2021; Kleinman, 2004). The current study explores the relationship between suicide and depression among six broad cultural groups in a large sample (N = 17,015) of adults representing six broad cultural groups (Latin America, South Asia, former Soviet Bloc, Western English-speakers, Chinese, and Arab World). Participants were recruited to a multilingual depression and suicide screening study via Google Ads (Leykin et al., 2012; Gross et al., 2014). As expected, the presence of depression was associated with suicide attempts. However, cultural group moderated this association, with Chinese participants being most likely to report suicide attempts while screening negative for depression. Although depression remains an important predictor of suicidality, it appears that certain cultural groups may be at higher risk even when depression is not present. Clinicians should consider using culturally adapted assessments for depression and suicidality.

Discrepancies in suicide screenings: Results from an international study.

BACKGROUND: When screening for suicidality, clinicians usually ask questions in ascending order of severity. Clinicians often discontinue questioning after negative responses to the first question or questions, presuming that these individuals are unlikely to endorse any further suicidality. In this study, the accuracy of this presumption is evaluated in a large international sample. METHODS: Participants were 21,385 individuals reporting a suicide attempt in the past two weeks. Participants were recruited, primarily via Google Ads, to a quintilingual (English, Spanish, Chinese, Arabic, and Russian) multinational depression and suicide screening study. RESULTS: Examining three initial screening questions (i.e., thoughts of death, wanting to die, and thinking about committing suicide), 14.8 % (n = 3179) of participants denied one or more question, 3.96 % (n = 847) denied two, and 1.95 % (n = 416) denied all three questions. The proportions of individuals with discrepant responses differed between linguistic-geographical groups, with Chinese and South Asian groups being more likely to be discrepant across all questions (all ps < .001). LIMITATIONS: Suicidality was assessed using an internet-based self-report measure, and linguistic-geographical groups explored in this study are very broad, which may limit generalizability. CONCLUSIONS: Results suggest that prematurely discontinuing suicide screening may fail to capture some individuals who made a recent attempt, and that in some groups, this discrepancy may be more pronounced. Clinicians should assess all individuals as thoroughly as possible regardless of initial responses, inquire about other significant risk factors, and be culturally sensitive.

Perceived Discrimination, Experiential Avoidance, and Mental Health among Hispanic Adults in Primary Care.

The Hispanic population is the largest minority group in the United States and frequently experiences racial discrimination and mental health difficulties. Prior work suggests that perceived racial discrimination is a significant risk factor for poorer mental health among Hispanic in the United States. However, little work has investigated how perceived racial discrimination relates to anxiety and depression among Hispanic adults. Thus, the current study evaluated the explanatory role of experiential avoidance in the relation between perceived racial discrimination and anxiety/depressive symptoms and disorders among Hispanic adults in primary care. Participants included 202 Spanish-speaking adults (Mage = 38.99, SD = 12.43, 86.1% female) attending a community-based Federally Qualified Health Center. Results were consistent with the hypothesis that perceived racial discrimination had a significant indirect effect on depression, social anxiety, and anxious arousal symptoms as well as the number of mood and anxiety disorders through experiential avoidance. These findings suggest future work should continue to explore experiential avoidance in the association between perceived racial discrimination and other psychiatric and medical problems among the Hispanic population.

Evaluating the Role of Anxiety Sensitivity on Behavioral Health Outcomes among Latinx Persons.

Background: Mexican Americans represent the largest subpopulation among Latinx persons and experience numerous health inequalities for psychological symptoms and behavioral health problems. First generation Mexican Americans are particularly vulnerable to such disparities and past work suggests that the experience of acculturative stress may play a vital role in terms of mental and physical health problems among this population. The current study sought to bridge past work on acculturative stress among first-generation Mexican Americans by exploring the role of anxiety sensitivity (AS; fear of the negative consequences of internal sensations) as a potential mediational factor in terms of psychological and behavioral health problems among this group. Methods: The current study consisted of 369 first generation Mexican American persons (86.2% female, 40.1 years of age (SD = 11.1) years in the U.S. attending a Federally Qualified Healthcare Center located in an urban southwestern community. We explored whether AS served as a mediator between acculturative stress and some of the most common and disabling clinical problems among this group, including social anxiety, anxious arousal, general depression, insomnia and pain intensity and disability. Result: Consistent with prediction, there was a statistically significant indirect effect of acculturative stress via AS across all criterion variables apart from pain intensity (depression [ab = - 0.17, SE = 0.05, 95% CI [0.08, 0.26]], insomnia [ab = 0.07, SE = 0.02, 95% CI [0.03, 0.10]], social anxiety [ab 0.05, SE = 0.02, 95% CI [0.02, 0.08]], anxious arousal [ab = 0.08, SE = 0.03, 95% CI [0.03, 0.12]], pain disability [ab = 0.05, SE = 0.02, 95% CI [0.02, 0.09]]). Comparative models were run to evaluate the specificity of hypothesized statistically significant models. For all models except anxious arousal and general depression, the alternative model was rejected, adding support to the hypothesized pathway. Conclusion: Overall, this work provides initial support for the role of AS in terms of the relation between acculturative stress and numerous psychological and behavioral health problems among Mexican American adults in a clinical setting.

Anxiety sensitivity and acculturative stress: Concurrent relations to mental health among Spanish-speaking Latinx in primary care.

The Latinx population suffers from mental health inequalities. Although past work has implicated acculturative stress and anxiety sensitivity as important individual difference factors for anxiety and depression in this group, it is presently unclear how they work together to influence more severe anxiety and depressive symptom expression among Latinx. To help address this gap in the existing literature, the current study evaluated the role of concurrent anxiety sensitivity and acculturative stress, in terms of anxiety and depressive symptoms and disorders, in a Latinx population in a primary care setting. Participants included 142 Latinx individuals (86.7% female; Mage = 39.66, SD = 11.34). After accounting for shared variance, the results indicated that both anxiety sensitivity and acculturative stress were significantly associated with anxious arousal symptoms, social anxiety, and depressive symptoms. However, anxiety sensitivity, but not acculturative stress, was significantly related to a number of mood and anxiety disorders. These findings suggest the importance of assessing both anxiety sensitivity and acculturative stress in routine mental health screening, as both factors may be related to poorer psychological health among this group.

Group cognitive-behavioral therapy for depression in Spanish: culture-sensitive manualized treatment in practice.

The authors applied cognitive-behavioral therapy (CBT) for depression using the Healthy Management of Reality treatment manual. This 16-week group treatment comprised four 4-week modules: thoughts (cognitive restructuring), activities (behavioral activation), people (interpersonal skills training), and health (addresses physical health and depression). They illustrated the use of the culture-sensitive treatment manuals by way of the member characteristics and clinical process of a Spanish-language CBT group for depression. They highlighted the challenges and satisfactions of working with a Spanish-speaking population in the public sector, and focused on how culture and socioeconomic status influence patients, and how to adapt treatment to these factors. Last, they demonstrated how technological advances integrate with culture-sensitive, evidence-based treatments to better serve this population and reduce disparities.

Children and adolescents attempting to participate in a worldwide online depression screener.

Depression rates are increasing among minors. Internet is central to the lives of many minors, and many of them look online for depression information. This report describes minors who attempted to screen themselves for depression in a worldwide online study. Google Ads were used to recruit individuals to a multilingual depression screening study that was meant to target and recruit adults. Of 158,170 individuals accessing the site, 30,396 (19.22%) were minors from 190 countries. Proportions of minors varied considerably between different cultures. Given youth's interest in depression information, online services to ethically and effectively address youth depression are needed.

Factor structure and psychometric properties of the Modified Scale for Suicidal Ideation among suicidal youth.

BACKGROUND: Although suicidal behaviors occur at a high rate in adolescence, relatively few interview-based measures are available to assess suicidal ideation among youth. Existing interview measures are limited by a paucity of empirical study, a failure to conform to standard suicide nomenclature, or a lengthy administration time. This study presents data on the psychometric properties and factor structure of the brief, layperson-administered Modified Scale for Suicidal Ideation (MSSI) among suicidal youth. METHODS: The MSSI was administered to an inpatient sample of 102 suicidal youth aged 13-17 years. Additional interview and self-report measures were administered to examine the convergent validity of the MSSI. RESULTS: Consistent with previous findings among suicidal adults, the MSSI displayed good internal consistency and expected patterns of convergent validity. Principal component analysis revealed a bidimensional structure, with factors corresponding to (1) Desire and Ideation and (2) Plans and Preparations. Each factor displayed acceptable internal consistency and expected patterns of convergent validity via associations with hopelessness, depressive symptoms, impulsivity, and a self-report measure of suicidal behaviors. The Plans and Preparations factor significantly associated with the presence of a current suicide attempt and with greater suicide intent among attempters, whereas the Desire and Ideation factor did not. CONCLUSIONS: The MSSI appears to be a reliable and valid instrument to assess suicidal ideation among distressed youth. Clinicians are encouraged to pay particular attention to responses on the Plans and Preparations factor given its stronger association with suicide attempt and more serious suicide intent.

Problem solving moderates the effects of life event stress and chronic stress on suicidal behaviors in adolescence.

The present study examined the unique and interactive effects of stress and problem-solving skills on suicidal behaviors among 102 inpatient adolescents. As expected, life event stress and chronic stress each significantly predicted suicidal ideation and suicide attempt. Problem solving significantly predicted suicidal ideation, but not suicide attempt. Problem solving moderated the associations between life event stress and suicidal behaviors, as well as between chronic stress and suicidal ideation, but not chronic stress and suicide attempt. At high levels of stress, adolescents with poor problem-solving skills experienced elevated suicidal ideation and were at greater risk of making a nonfatal suicide attempt. The interactive effects decreased to non-significance after controlling for depressive symptoms and hopelessness. Clinical implications are discussed.
