Objective: Although parental threatening behaviors are associated with poor mental health outcomes among college students, the underlying mechanisms of this relationship are understudied. This investigation examined the underlying role of perceived anxiety control in the association between childhood exposure to maternal threatening behaviors and depression, worry, and attention/deficit hyperactivity disorder (attention-deficit/hyperactivity disorder) symptoms. Participants: Participants ( N  = 862; M age = 18.75 years, SD  = 1.04, age range = 18-24) were recruited from a large state university in the northeast. Methods: Participants completed a battery of self-report questionnaires. Results: Tests of indirect effects indicated that greater childhood exposure to maternal threats was associated with lower perceived anxiety control, which in turn was associated with more severe depression, worry, and ADHD symptoms, respectively. Conclusions: Childhood exposure to maternal threatening behaviors may contribute to college students' low perceived anxiety control, which in turn increases the risk for these symptom clusters.

Cigarette smoking is associated with adverse physical and mental health among Latinx adults in the United States. The present investigation sought to explore the main and interactive effects of anxiety symptoms and anxiety sensitivity in relation to cigarette dependence, perceived barriers for smoking cessation, and severity of problems experienced when quitting among adult Latinx smokers. Participants included 338 Latinx adult daily cigarette smokers ( M age = 35.53 years; SD  = 8.65; age range 18-61; 37.3% female). Results indicated that anxiety symptoms were associated with greater cigarette dependence, severity of problems when quitting, and perceived barriers for smoking cessation (effect size range: 2%-3% of variance), whereas anxiety sensitivity was related to severity of problems when quitting and perceived barriers for smoking cessation (effect size range: 2%-3% of variance). There was also a statistically significant interaction between anxiety sensitivity and anxiety symptoms for cigarette dependence; anxiety was related to cigarette dependence for Latinx smokers with higher levels of anxiety sensitivity, but not for those with lower levels of anxiety sensitivity. Overall, the present findings indicate that anxiety symptoms and anxiety sensitivity are relevant factors for better understanding cigarette dependence, problems experienced when trying to quit, and perceptions of barriers to quitting among adult Latinx smokers.

Hispanic persons in the United States (US) experienced a disproportionate proportion of adverse health consequences during the pandemic and are a well-established tobacco disparities population. The tendency to worry is one individual difference cognitive-affective construct that is important to smoking behavior and stress-related experiences during the COVID-19 pandemic. However, there is limited understanding of COVID-19 worry in terms of smoking processes among Hispanic persons who smoke during the pandemic. The present investigation examined if COVID-19 worry during the pandemic (February 2021-July 2021) was associated with several processes linked to the maintenance and relapse of smoking among Hispanic persons who smoke. Participants included 337 Hispanic persons who smoke (≥5 cigarettes per day; M age = 35.5 years old, 37.3% identified as female). Results indicated that in adjusted models covarying for the effects of sex, age, highest level of education, nativity, average number of cigarettes smoked per day, hazardous drinking, drug use problems, and depression, COVID-19 worry was related to increased risk of cigarette dependence, perceived barriers for quitting smoking, and more severe problems when trying to quit. These data are the first to identify an association between heightened COVID-19 worry and risk processes related to the maintenance and relapse of smoking among the Hispanic population in the US.

Introduction: The COVID-19 pandemic posed a threat to public health and psychological functioning, with early studies documenting higher rates of psychopathology within the United States and globally. Hope and optimism promote adjustment and are associated with positive physical and mental health outcomes. Thus, individual differences in hope and optimism may also foster resilience during a global health crisis., Aims: The current study examined how hope and optimism influenced longitudinal health-focused distress and wellbeing during the pandemic., Methods: Data were collected from 788 American adults across three periods during Spring-Summer 2020 using MTurk. Latent growth curve modeling examined whether hope and optimism predicted COVID stress, health anxiety, and wellbeing trajectories., Results: COVID stress and health anxiety decreased after the onset of the pandemic, whereas wellbeing was stable. Individually, hope and optimism predicted lower initial COVID stress and health anxiety, along with greater initial wellbeing. When examining the combined influence of hope and optimism, optimism was more strongly related to health-focused distress, though both were strong predictors of wellbeing., Conclusions: These findings indicate that Americans were resilient and positive expectancies, particularly optimism, predicted better initial adjustment to the early phases of the pandemic. Thus, positive expectancies appear to be protective during a global health crisis., (© 2024 Wiley Periodicals LLC.)

Objective: Posttraumatic stress symptoms (PTSS) and anxiety sensitivity (AS) are associated with increased alcohol use and coping-motivated drinking among university students. This study among trauma-exposed Hispanic/Latinx university students sought to examine the indirect effect of PTSS on alcohol use severity through coping-motivated drinking and test the moderating role of AS and AS subfacets., Methods: University students who identified as Hispanic/Latinx ( N  = 830) were recruited from a large, urban, southern university and completed online, self-report questionnaires., Results: A significant interactive effect of PTSS and AS on coping-motivated drinking emerged. PTSS exerted a significant indirect effect on alcohol use severity, through coping-motivated drinking. Simple slope analyses revealed that PTSS was associated with coping-motivated drinking across all levels of AS. Post hoc results revealed unique biological sex differences in probable diagnosis odds ratios., Conclusions: These findings indicate that PTSS and AS are associated with coping-motivated drinking and alcohol use severity in trauma-exposed, Hispanic/Latinx university students.

As a multi-systemic disease, COVID-19 infection engendered a rise in co-occurring mental and physical health symptoms, particularly affecting the Latinx population. The current work sought to evaluate the main and interactive influence of acculturative stress and anxiety sensitivity in terms of mental and physical health symptoms among 181 Latinx persons (30.4% female, M age  = 34.1 years, SD  = 8.20). Data were collected during a period of high COVID-19 impact (2020-2021) and analyses included five separate, two-step hierarchical regressions that were conducted for each of the criterion variables: (1) fear of coronavirus; (2) somatic symptoms; (3) fatigue severity; (4) anxiety symptoms; and (5) depression symptoms. For all analyses, step 1 covariates included years living in the U.S. COVID-19 impact, gender identity, education, and work life distress and home life distress. Results revealed an interactive effect of anxiety sensitivity and acculturative stress on COVID-19 fear, unique main effects for both anxiety sensitivity and acculturative stress on COVID-19 related fear and somatic symptoms, and main effects for anxiety sensitivity alone in relation to fatigue severity, anxiety, and depression. Overall, this study represents an initial investigation of the associations between acculturative stress, anxiety sensitivity, and a range of salient COVID-19 related outcomes among Latinx persons.

Introduction: Distress during pregnancy and postpartum is common and contributes to poor infant and maternal outcomes, such as developmental delays and mental health disorders, respectively. Anxiety sensitivity, or fear of the symptoms of anxiety (eg, palpitations, confusion), is a risk factor known to increase distress across psychological and health-related conditions. Given the physiologic and emotional changes that occur during the perinatal period, anxiety sensitivity may be a salient risk factor for maternal distress. In this pilot study, we aimed to understand the unique role of prenatal anxiety sensitivity in postpartum psychological and parenting distress., Methods: Twenty-eight pregnant women (mean age, 30.86 years) were recruited from the community in a Southeastern metropolitan area of the United States. Participants completed self-report measures during their third trimester of pregnancy and again within 10 weeks postpartum. The Depression Anxiety and Stress Scales-21 and the Parenting Distress subscale of the Parenting Stress Index-4-Short Form were the primary postpartum outcome measures., Results: Prenatal anxiety sensitivity was elevated in this sample relative to convenience samples. Prenatal anxiety sensitivity uniquely contributed to postpartum psychological (b, 1.01; P < .001) and parenting distress (b, 0.62; P = .008), after accounting for age, gravidity, and gestation., Discussion: Albeit preliminary, results suggest prenatal anxiety sensitivity may be an important and malleable risk factor associated with several mental health concerns common in the perinatal period. Anxiety sensitivity may be targeted with brief interventions to prevent or reduce postpartum distress. Reducing prenatal anxiety sensitivity has the potential prevent the onset or worsening of psychological disorders among women and, in turn, may improve infant and child outcomes. Future studies should replicate these findings in a larger sample., (© 2023 by the American College of Nurse-Midwives.)

Public concerns over environmental protection have increased after Fukushima accident. The soil-plant transfer factor (Fv) is a critical parameter for environmental risk assessment. 137 Cs Fv values determined in acid Brazilian soils could be two orders of magnitude higher than Fv values measured in soils affected by the Chernobyl accident. This paper studied the behaviour of 90 Sr in Brazilian soils where very few 90 Sr Fv data is available. All classes of studied soils (Ferralsol, Acrisol and Nitisol) showed that more than 80% of total 90 Sr in soils remains potentially mobile, mainly at the bioavailable phase, more than 2 years after soil contamination in an experiment conducted in lysimeters. Higher 90 Sr Fv for maize and cabbage was observed in the acid soils with low content of exchangeable Ca, lower Fv values occurred at Nitisol, the subtropical soil type. It seems that the behaviour of 90 Sr in these soils are mainly controlled by ionic competition mechanisms occurring for root uptake and sorption sites, with stable Sr and major nutrients (Ca, Mg and K). The mineralogy also seems to play a relevant role, since goethite rich clay soil presented 90 Sr Fv values higher one or two orders of magnitude than 90 Sr Fv values observed at clayed soil goethite rich with trace of vermiculite, for all studied crops. The high rate of 90 Sr migration down the soil profiles observed for the studied soils during the 2 first years after contamination suggests a high rate of transfer to groundwater, even transfer to leafy crop group can be also a relevant pathway. In the present study, maize, among other plant species, presented the lowest Fv values, even when compared with maize cultivated in temperate soil. Our results suggest that stable Sr may not be a very good analogue of 90 Sr for determining plant Fv values: geometric mean of stable Sr Fv for maize was Fv maize  = 6.3E-1 ± 2.1E0 (n = 8) and for 90 Sr was Fv maize  = 1.8E-2 ± 2.5E0 (n = 16), geometric mean of stable Sr Fv for cabbage was Fv cabbage  = 1.4E0 ± 3.9E0 (n = 17) and for 90 Sr was Fv cabbage  = 7.9E-1 ± 4.4E0 (n = 18)., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Hispanic/Latinx (hereafter Latinx) smokers in the United States (US) experience unique smoking cessation-related challenges. Smoking outcome expectancies (i.e., positive and negative beliefs about the consequences of smoking behavior) have been linked to the maintenance of smoking and comorbidity with negative emotional states such as anxiety among Latinx smokers. However, past work has not characterized rates of probable anxiety disorder and elevated levels of anxiety sensitivity among English-speaking daily Latinx smokers from the United States or concurrently evaluated the explanatory relevance of anxiety symptoms and anxiety sensitivity for negative and positive smoking outcome expectancies. The present investigation sought to (a) determine the base rate of probable anxiety disorder and elevated anxiety sensitivity and (b) explore the unique roles of anxiety symptoms and anxiety sensitivity in relation to negative and positive smoking outcome expectancies. Participants included 338 English-speaking Latinx adult daily cigarette smokers from the United States ( M age = 35.53 years; SD = 8.65; age range 18-61; 37.3% female). Findings revealed high rates of probable anxiety disorder (50.9%) and elevated anxiety sensitivity (73.4%) among English-speaking Latinx smokers from the United States. Anxiety sensitivity, but not anxiety symptoms or disorders, was significantly related to negative consequences, negative reinforcement, positive reinforcement, and appetite/weight control smoking outcome expectancies. Overall, anxiety experiences were common among Latinx smokers, and anxiety sensitivity was a relatively more consistent and robust predictor of negative and positive outcome expectancies relative to anxiety symptoms and probable anxiety disorder.

Objective: Hispanic/Latina students experience elevated rates of binge drinking, interpersonal trauma, and posttraumatic stress disorder (PTSD) symptoms. Research has indicated anxiety sensitivity (AS; i.e., fear of anxiety-related bodily sensations) and distress tolerance (DT; i.e., ability to tolerate negative emotional states) are modifiable psychological mechanisms related to alcohol use and PTSD symptoms. However, a dearth of literature has focused on factors that may account for associations between alcohol use and PTSD among Hispanic/Latina students., Method: The project examined, among 288 Hispanic/Latina college students ( M age = 23.3 years, SD = 5.4) with interpersonal trauma histories, the indirect effects of PTSD symptom severity on (a) alcohol use and (b) alcohol use motives (i.e., coping, conformity, enhancement, social) via DT and AS, evaluated as parallel statistical mediators., Results: Results PTSD symptom severity had an indirect effect on (a) alcohol use severity; (b) conformity motives for alcohol use; and (c) social motives for alcohol use via AS but not DT. PTSD symptom severity was associated with coping-oriented drinking via both AS and DT., Conclusions: This research has the potential to advance culturally-informed literature on factors that may impact co-occurring PTSD symptoms and alcohol use.

Background: Although childhood exposure to parental threatening behaviors is associated with elevated anxiety in emerging adulthood, the underlying mechanisms remain unexplored. Perceived stress-a subjective experience comprised of feelings of helplessness (being unable to cope or exert control) and poor self-efficacy (confidence in one's ability to manage stressors)-is one candidate mechanism. The present investigation examined the underlying role of perceived stress in the association between childhood exposure to parental threatening behaviors and anxiety symptom severity in a sample of emerging adults., Methods: Participants (N = 855; M age  = 18.75 years, SD = 1.05, range 18-24; 70.8% female) were recruited from a large state university and administered a battery of self-report questionnaires assessing constructs of interest., Results: Structural equation modeling (SEM) analyses indicated that only greater childhood exposure to maternal threatening behaviors was directly associated with greater feelings of helplessness and lower self-efficacy. Furthermore, only childhood exposure to maternal threatening behaviors was indirectly associated with anxiety severity through greater feelings of helplessness and lower self-efficacy. In contrast, childhood exposure to paternal threatening behaviors was neither directly nor indirectly associated with anxiety severity., Limitations: Limitations include a cross-sectional design, use of self-report measures, and a nonclinical sample. Replicating these findings in a clinical sample and testing the hypothesized model in a longitudinal design is necessary., Conclusions: Findings underscore the need for intervention efforts that screen for and target perceived stress in emerging adults exposed to negative maternal parenting behaviors., (© 2023 Wiley Periodicals LLC.)

Trauma-exposure and posttraumatic stress symptoms increase risk for opioid-related problems in the context of chronic pain. Yet, there has been little exploration of moderators of the posttraumatic stress-opioid misuse association. Pain-related anxiety, defined as worry about pain and the negative consequences of pain, has shown relations to both posttraumatic stress symptoms and opioid misuse, and it may moderate the association between posttraumatic stress symptoms and opioid misuse, as well as dependence. The current study examined the moderating role of pain-related anxiety on the relationship between posttraumatic stress symptoms and opioid misuse and dependence among 292 (71.6 % female, M age  = 38.03 years, SD = 10.93) trauma exposed adults with chronic pain. Results indicated that pain-related anxiety significantly moderated the observed relations, such that compared to those with low pain-related anxiety, the relationship between posttraumatic stress symptoms and opioid misuse and dependence was stronger for those with elevated pain-related anxiety. These results highlight the importance of assessing and targeting pain-related anxiety among this trauma-exposed segment of the chronic pain population with elevated posttraumatic stress symptoms., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Latinx persons are exposed to higher rates of traumatic events and conditional risks for developing posttraumatic stress disorder (PTSD) symptoms and comorbid mental health symptoms compared to other minority groups. The study evaluated PTSD symptom severity for global and specific cluster severity relating to co-occurring anxiety, social anxiety, depression, and suicidal ideation among 326 Latinx adults who endorsed trauma exposure. Results indicated that global PTSD symptom severity was significantly related to greater social anxiety, anxious arousal, depression, and suicidal ideation symptoms. PTSD arousal and reactivity symptom cluster had the strongest relation to anxious arousal, social anxiety, and depression, whereas negative alterations in cognitions and mood symptoms had the strongest association with social anxiety, depression, and suicidal ideation. The findings suggest that global PTSD symptom severity, alongside arousal and reactivity and negative alterations in cognitions and mood, are related to a range of concurrent negative mental health symptoms among trauma exposed Latinx young adults.

Anxiety disorders are the most common class of psychiatric conditions among children and adolescents. The cognitive behavioral model of childhood anxiety has a strong theoretic and empirical foundation that provides the basis for effective treatment. Cognitive behavioral therapy (CBT), with an emphasis on exposure therapy, is the gold standard treatment for childhood anxiety disorders, with strong empirical support. A case vignette demonstrating CBT for childhood anxiety disorders in practice, as well as recommendations for clinicians, are also provided., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Abstract: The present investigation examined associations of childhood maltreatment, anxiety sensitivity (AS), and sleep disturbance among a diverse sample of adults in psychiatric inpatient treatment. We hypothesized that childhood maltreatment would be indirectly associated with greater sleep disturbance through elevated AS. Exploratory analyses examined the indirect effect models with three AS subscales ( i.e. , physical, cognitive, and social concerns) as parallel mediators. A sample of adults in acute-care psychiatric inpatient treatment ( N = 88; 62.5% male; Mage = 33.32 years, SD = 11.07; 45.5% White) completed a series of self-report measures. After accounting for theoretically relevant covariates, childhood maltreatment was indirectly associated with sleep disturbance through AS. Parallel mediation analyses revealed that no individual subscale of AS significantly accounted for this association. These findings suggest that heightened levels of AS may explain the association between childhood maltreatment and sleep disturbance among adults in psychiatric inpatient treatment. Interventions targeting AS can be brief and efficacious and have the potential to improve clinical outcomes among psychiatric populations., (Copyright © 2023 Wolters Kluwer Health, Inc.

The mental and behavioral health burden resulting from COVID-19 has disproportionately affected the Latinx population. Yet, no work has investigated the influence of resilience as a protective factor against COVID-19 related consequences. The aim of the current study was to evaluate resilience in relation to COVID-19 related fear, anxiety symptoms, COVID-19 anxiety-related sleep disturbances, and depression among Latinx persons (178 Latinx persons [31.5% female, M age  = 34.1 years, SD  = 8.2]). It was hypothesized that greater levels of resilience would be associated with lower levels of all COVID-19 related behavioral health outcomes above and beyond the variance accounted for by years living in the United States (U.S.), degree of COVID-19 exposure, sex, age, education, and COVID-19 related work and financial troubles and home-life distress. Results indicated that greater levels of resilience were associated with lower levels of COVID-19 related fear ( ΔR 2  = .06, p  < .001), anxiety symptoms ( ΔR 2  = .03, p  = .005), COVID-19 anxiety-related sleep disturbances ( ΔR 2  = .06, p  < .001), and depression ( ΔR 2  = .04, p  = .001). Overall, the present study is the first to document the potential importance of resilience in relation to common and clinically significant COVID-19 behavioral health problems among Latinx persons.

The present study investigated the interactive effect of reactive (negative emotionality) and regulatory (effortful control) aspects of temperament in the prediction of child anxiety and depressive symptoms. Clinically anxious children and their mothers completed a battery of questionnaires that included self- and mother-ratings of child effortful control, negative emotionality, anxiety, and depressive symptoms. Multiple regression analyses were conducted to examine the moderating effect of effortful control on the relation between negative emotionality and child anxiety and depressive symptom severity. The interaction between negative emotionality and effortful control was statistically significant and simple slopes revealed that as effortful control increased, the relationship between negative emotionality and anxiety and depressive symptoms weakened. Among anxious children high in negative emotionality, greater effortful control was related to less severe anxiety and depressive symptoms. Future work should evaluate whether targeting effortful control leads to reductions in internalizing symptoms among clinically anxious youth., (© 2021.

Obesity is one the fastest growing public health problems related to numerous chronic diseases and frequently co-occurs with negative mood states. One promising approach to address the heterogeneity of affective vulnerabilities and obesity is to focus on processes (e.g. anxiety sensitivity [AS]) that underpin both conditions. Thus, this study aimed to evaluate the feasibility, acceptability, and initial efficacy of a brief, computer-delivered AS reduction program (AST) for adults with obesity and elevated AS. Participants were 131 individuals with obesity and elevated AS who received either AST or a health information control (HC). Latent growth curve modeling was utilized to examine the effect of treatment condition on change in AS, emotional eating, expectancies of eating to manage mood, and exercise self-efficacy from baseline to 1-week, 2-weeks, and 1-month follow-up. Results indicated it was feasible to recruit and retain individuals with obesity and elevated AS through the 1-month follow-up. Positive qualitative feedback was also provided for both AST and HC. AST was a statistically significant predictor of change in expectancies of eating to manage negative affect. No other statistically significant treatment effects were indicated. Current data provide initial empirical support for future work focused on persons with obesity and elevated AS.

The COVID-19 pandemic is associated with an increased prevalence of mental health problems and addictive behaviors. There is a growing theoretical and empirical evidence that individual differences in interoceptive anxiety-related processes are a one set of vulnerability factors that are important in understanding the impact of pandemic-related mental health problems and addictive behavior. However, there has not been a comprehensive effort to explore this rapidly growing body of research and its implications for public health. In this paper, we discuss why interoceptive anxiety-related processes are relevant to understanding mental health and addictive behaviors during the COVID-19 pandemic. We then provide a narrative review of the available COVID-19 literature linking interoceptive fear and anxiety-related processes (e.g., anxiety sensitivity, health anxiety, and COVID-19 anxiety, fear, and worry) to mental health and addictive behaviors. We then propose a novel transdiagnostic theoretical model that highlights the role of interoceptive anxiety-related processes in mental health and addictive behavior in the context of the present and future pandemics. In the final section, we utilize this conceptualization to underscore clinical implications and provide guidance for future research initiatives in the management of COVID-19 mental health and addictive behaviors and inform the public health field for future pandemics., (Copyright © 2022 Elsevier Ltd.

Rates of traumatic event exposure, posttraumatic stress (PTS), and co-occurring mental health symptoms and disorders are conditionally higher among Latinx individuals compared to other racial/ethnic populations. Importantly, Latinx persons are a heterogeneous population, and certain subgroups endorse higher rates of negative mental health outcomes than others, including Latinx young adults born in the USA. Yet, there is little understanding of individual difference factors among trauma-exposed US born Latinx young adults that may be involved in mental health burden among this group. The present investigation sought to evaluate the potential explanatory relevance of heart-focused anxiety as an individual difference factor regarding some of the most common co-occurring mental health problems among trauma-exposed populations. Specifically, we tested whether heart-focused anxiety was related to increased co-occurring anxious arousal symptoms, depression, social anxiety, and suicidality among 169 (84% female, M age =23.15 years, SD=6.07) trauma-exposed Latinx young adults. Results indicated that heart-focused anxiety was a statistically significant predictor of general depression (ΔR 2 = .02, F(1, 161) = 4.25, p = .041), suicidality (ΔR 2 = .10, F(1, 161) = 21.49, p < .001), anxious arousal (ΔR 2 = .11, F(1, 161) = 27.31, p < .001), and social anxiety (ΔR 2 = .03, F(1, 161) = 7.93, p = .005). Overall, this work offers empirical evidence that individual differences in heart-focused anxiety are related to more severe co-occurring anxiety and depressive symptomatology among a particularly at risk Latinx segment of the Latinx population (non-immigrant Latinx young adults s with previous trauma history)., (© 2021.

Myelodysplastic syndrome (MDS) is a hematological disorder characterized by abnormal stem cell differentiation and a high risk of acute myeloid leukemia transformation. Treatment options for MDS are still limited, making the identification of molecular signatures for MDS progression a vital task. Thus, we evaluated the proteome of bone marrow plasma from patients (n = 28) diagnosed with MDS with ring sideroblasts (MDS-RS) and MDS with blasts in the bone marrow (MDS-EB) using label-free mass spectrometry. This strategy allowed the identification of 1,194 proteins in the bone marrow plasma samples. Polyubiquitin-C (UBC), moesin (MSN), and Talin-1 (TLN1) showed the highest abundances in MDS-EB, and centrosomal protein of 55 kDa (CEP55) showed the highest relative abundance in the bone marrow plasma of MDS-RS patients. In a follow-up, in the second phase of the study, expressions of UBC , MSN , TLN1 , and CEP55 genes were evaluated in bone marrow mononuclear cells from 45 patients by using qPCR. This second cohort included only seven patients from the first study. CEP55 , MSN , and UBC expressions were similar in mononuclear cells from MDS-RS and MDS-EB individuals. However, TLN1 gene expression was greater in mononuclear cells from MDS-RS (p = 0.049) as compared to MDS-EB patients. Irrespective of the MDS subtype, CEP55 expression was higher (p = 0.045) in MDS patients with abnormal karyotypes, while MSN , UBC , and TALIN1 transcripts were similar in MDS with normal vs. abnormal karyotypes. In conclusion, proteomic and gene expression approaches brought evidence of altered TLN1 and CEP55 expressions in cellular and non-cellular bone marrow compartments of patients with low-risk (MDS-RS) and high-risk (MDS-EB) MDSs and with normal vs. abnormal karyotypes. As MDS is characterized by disrupted apoptosis and chromosomal alterations, leading to mitotic slippage, TLN1 and CEP55 represent potential markers for MDS prognosis and/or targeted therapy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Moura, Bezerra, Martins, Borges, Oliveira, Oliveira, Farias, Viana, Carvalho, Paier, Sousa, Fontes, Ricart, Moraes, Magalhães, Furtado, Moraes-Filho, Pessoa and Pinheiro.)

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 ( M age  = 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.

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; M age  = 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., (© 2022.

A fearful temperament in childhood is associated with child internalizing symptoms. However, the cognitive mechanisms explaining this association are poorly understood. We examined the effects of child fearful temperament on child internalizing symptoms and the underlying role of catastrophizing cognitions among clinically anxious youth. Children ( N = 105; M age = 10.09 years, SD = 1.22; 56.7% female; 62% ethnic minority) completed a diagnostic interview; self-report measures of temperament, catastrophizing, and internalizing symptoms; and behaviorally-indexed measures of catastrophizing and anxiety. Indirect effects were found for child fearful temperament on child self-reported internalizing symptoms by way of self-reported (but not behaviorally-indexed) catastrophizing cognitions. Models predicting behaviorally-indexed child anxiety were not significant. Our findings suggest that targeting fearful temperament during childhood before catastrophizing cognitions develop may have clinical utility. Likewise, among children temperamentally at-risk, addressing catastrophic cognitions may prevent later internalizing psychopathology., (© Copyright 2022 Springer Publishing Company, LLC.)

In this work, we describe the synthesis, the characterization, and the potential application of a pH-responsive guar gum-based hydrogel. The polysaccharide produced permanent hydrogels with improved biocompatibility. In this work, we report the chemical modification of guar gum (with glycidyl methacrylate) and its use, as the main constituent, in obtaining chemically cross-linked hydrogels. The morphology, swelling properties, and cytotoxicity of the resulting materials were studied in-depth. The hydrogels showed to be pH-responsive, and non-toxic being safe to use it as a biomaterial. In addition, we tested the potential of this one as a drug carrier. Herein, we have chosen hydrocortisone (HCS) as a drug model. The mechanism of HCS release changed as a function of pH, owing to different responses in each medium. Our results indicate that the guar gum hydrogels have great potential to be used, with safety, as a drug carrier., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Background: The outbreak of the novel 2019 SARS2-Coronavirus disease (COVID-19) has led to substantial psychological distress across the United States and the world. However, emerging work suggests that prominent COVID-19 consequences such as fear of COVID-19 infection and emotional distress resulting from economic adversity and social distancing may afflict the Latinx population disproportionately. The current study sought to investigate the influence of experiential avoidance (EA), or an individual's tendency to rigidly avoid negative internal experiences (i.e. feelings, thoughts, etc.), on the severity of COVID-19 fear and emotional distress symptoms due to economic adversity and social distancing., Method: Participants included 188 Latinx persons recruited via an online survey panel program., Results: Results indicated that EA was a statistically significant contributing factor to fear of COVID-19 and emotional distress associated with economic adversity and social distancing.

Background: Latinx persons are overrepresented in terms of 2019 Coronavirus (COVID-19) infection rates and constitute a subpopulation at increased risk for COVID-19 related physical ailments. Fatigue and pain are among the most prevalent somatic symptoms among the Latinx population; however, there is little understanding of individual difference factors that are related to fatigue and pain during COVID-19 among this health disparities population. Experiential avoidance (EA) reflects the persistent tendency to avoid aversive internal sensations., Methods: The current study sought to extend past work by exploring EA in relation to fatigue severity, pain intensity, and pain disability among 182 Latinx adult persons during the COVID-19 pandemic., Results: Results indicated that EA accounted for a statistically significant amount of variance across the criterion variables., Conclusions: Overall, the current work provides initial empirical evidence that EA is related to greater fatigue severity and pain severity/disability among Latinx persons during COVID-19., Competing Interests: Conflict of InterestNubia A. Mayorga, Kara F. Manning, Lorra Garey, Andres G. Viana, Joseph W. Ditre, and Michael J. Zvolensky declare that they have no conflict of interest., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

Although anxiety symptoms/disorders are consistently implicated in smoking processes, no empirical work has identified individual difference factors that may underlie such relations among Latinx smokers. The current study examined anxiety sensitivity as an explanatory factor underlying the relationship between anxiety symptoms and smoking expectancies among Spanish-speaking Latinx smokers. Participants included 363 Spanish-speaking Latinx daily smokers (58.7% female, M age = 33.3 years, SD  = 9.81). Results indicated that anxiety symptoms had a significant indirect effect on positive and negative smoking expectancies through anxiety sensitivity. Such findings suggest that anxiety sensitivity is relevant to understanding the anxiety-smoking expectancies association among Latinx smokers.

Fearful temperament-the tendency to exhibit apprehension and/or avoidance in novel situations-is a well-established risk factor for childhood anxiety in general, and social anxiety in particular. Yet, there is little understanding of parent emotion socialization strategies that influence the association between fearful temperament and child social anxiety symptoms. The present investigation addresses this gap in the literature by examining maternal punitive responses to clinically anxious children's negative emotions as a moderator of the covariance between fearful temperament and social anxiety symptom severity. Clinically anxious children ages 8-12 years (N = 105; 57.1% female; 61.9% racial/ethnic minority) and their mothers completed measures assessing child fearful temperament, maternal punitive emotion socialization responses, and child social anxiety symptoms. Children also participated in an anxiety-provoking speech task during which manifest social anxiety was coded by trained observers. Children's fearful temperament coupled with greater maternal punitive responses to children's negative emotions was associated with lower child-reported social anxiety symptoms. Models predicting manifest social anxiety were not significant. Maternal punitive responses to children's negative emotions may encourage clinically anxious youth to approach feared situations and therefore result in lower anxiety. Yet, the potentially negative effects of punitive responses on other aspects of anxious children's socioemotional development warrant scientific attention. Future research should examine the phenomenology of punitive parental responses among parents of anxious youth to better understand their effects on child behavior., (© 2021.

Background: Visceral leishmaniasis (VL) is a serious public health problem. The factors that can determine whether VL develops and progresses to severe form have not been fully identified, but a specific cellular immune response appears to play a key role. Therefore, understanding immunopathogenesis can be useful in preventing a serious clinical outcome., Materials and Methods: Bone marrow samples were collected from patients with severe VL (SVL) or non-severe VL (NSVL). Cytokine levels and parasitic load were analysed by RT-qPCR. There is a statistically significant difference in the leukocyte parameter in patients with SVL and NSVL compared with the control patients (p = .006 and p = .014, respectively)., Results: Urea, alanine transaminase and albumin parameters had a significant difference p = .036, p = .039 and p = .017, respectively, between SVL and NSVL. Although high levels of IFN-γ, IL-10, IL-6 and TNF-α were present in all groups of individuals with VL, they were not statistically associated with severity. In patients with active VL, IFN-γ and IL-10 were associated, respectively, with a reduction and increase in the parasite load, strong and significant positive association between IFN-γ and IL-10 (rho = .627 and p = .003)., Conclusion: This study demonstrates that VL stimulates an non-dichotomized inflammatory response between Th1/Th2 and that bone marrow is an important tissue for immune regulation., (© 2021 John Wiley & Sons Ltd.)

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; M age  = 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.

Little is understood about individual difference factors related to e-cigarette expectancies about use. This study examined the interactive effects of fatigue severity and anxiety sensitivity in relation to e-cigarette expectancies among 525 e-cigarette users (51.0% female, M age  = 35.25 years, standard deviation = 10.10). Results indicated a significant interaction between fatigue severity and anxiety sensitivity in terms of positive expectancies ( β  = 0.57, p  < 0.001, 95% confidence interval = (0.002, 0.01)), but not for negative expectancies ( β  = 0.25, p  = 0.08, 95% confidence interval = (0, 0.005)) for e-cigarette use. These results support anxiety sensitivity as a moderator in the relation between fatigue severity and positive outcome expectancies for e-cigarette use.

Visceral leishmaniasis (VL) is caused by protozoa belonging to the Leishmania donovani complex and is considered the most serious and fatal form among the different types of leishmaniasis, if not early diagnosed and treated. Among the measures of disease control stand out the management of infected dogs and the early diagnosis and appropriate treatment of human cases. Several antigens have been characterized for use in the VL diagnosis, among them are the recombinant kinesin-derived antigens from L. infantum, as rK39 and rKDDR. The main difference between these antigens is the size of the non-repetitive kinesin region and the number of repetitions of the 39 amino acid degenerate motif (6.5 and 8.5 repeats in rK39 and rKDDR, respectively). This repetitive region has a high antigenicity score. To evaluate the effect of increasing the number of repeats on diagnostic performance, we designed the rKDDR-plus antigen, containing 15.3 repeats of the 39 amino acid degenerate motif, besides the absence of the non-repetitive portion from L. infantum kinesin. Its performance was evaluated by enzyme-linked immunosorbent assay (ELISA) and rapid immunochromatographic test (ICT), and compared with the kinesin-derived antigens (rKDDR and rK39). In ELISA with human sera, all recombinant antigens had a sensitivity of 98%, whereas the specificity for rKDDR-plus, rKDDR and rK39 was 100%, 96% and 71%, respectively. When evaluated canine sera, the ELISA sensitivity was 97% for all antigens, and the specificity for rKDDR-plus, rKDDR and rK39 was 98%, 91% and 83%, respectively. Evaluation of the ICT/rKDDR-plus, using human sera, showed greater diagnostic sensitivity (90%) and specificity (100%), when compared to the IT LEISH (79% and 98%, respectively), which is based on the rK39 antigen. These results suggest that the increased presence of repetitive motifs in the rKDDR-plus protein improves the diagnostic performance of serological tests by increasing the specificity and accuracy of the diagnosis., Competing Interests: I have read the journal’s policy and the authors of this manuscript have the following competing interests: the Safetest Diagnósticos licensed the KDDR-plus antigen. However, this company had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.

Ascaris lumbricoides and Ascaris suum are two closely related parasites that infect humans and pigs. The zoonotic potential of A. suum has been a matter of debate for decades. Here we sought to investigate the potential human infection by A. suum and its immunological alterations. We orally infected five healthy human subjects with eggs embraced by A. suum. The infection was monitored for symptoms and possible respiratory changes, by an interdisciplinary health team. Parasitological, hematological analyses, serum immunoglobulin, cytokine profiles, and gene expression were evaluated during the infection. Our results show that A. suum is able to infect and complete the cycle in humans causing A. lumbricoides similar symptoms, including, cough, headache, diarrhea, respiratory discomfort and chest x-ray alterations coinciding with larvae migration in the lungs. We also observed activation of the immune system with production of IgM and IgG and a Th2/Th17 response with downregulation of genes related to Th1 and apoptosis. PCA (Principal componts analysis) show that infection with A. suum leads to a change in the immune landscape of the human host. Our data reinforce the zoonotic capacity of A. suum and bring a new perspective on the understanding of the immune response against this parasite., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2021.

Background: Proton radiotherapy (PRT) may be associated with less neurocognitive risk than photon RT (XRT) for pediatric brain tumor survivors. We compared neurocognitive and academic outcomes in long-term survivors treated with XRT versus PRT., Methods: Survivors underwent neurocognitive evaluation >1 year after craniospinal (CSI) or focal PRT or XRT. Groups were compared using separate one-way analyses of covariance for the CSI and focal groups., Results: PRT (n = 58) and XRT (n = 30) subgroups were similar on gender (66% male), age at RT (median = 6.5 years), age at follow-up (median = 14.6 years), and government assistance status (32%). PRT and XRT focal groups differed on follow-up interval, shunt history, and total RT dose (all p < .05), whereas PRT and XRT CSI groups differed on follow-up interval, baseline neurocognitive performance score, boost volume, and CSI dose (all p < .05). The PRT focal group outperformed the XRT focal group on inhibition/switching (p = .04). The PRT CSI group outperformed the XRT CSI group on inattention/impulsivity (both p < .05). Several clinical variables (i.e., RT dose, boost field, baseline performance) predicted neurocognitive outcomes (all p < .05). The PRT focal group performed comparably to population means on most neurocognitive measures, while both CSI groups performed below expectation on multiple measures. The XRT CSI group was most impaired. All groups fell below expectation on processing speed, fine motor, and academic fluency (most p < .01)., Conclusions: Findings suggest generally favorable neurocognitive and academic long-term outcomes following focal PRT. Impairment was greatest following CSI regardless of modality. Dosimetry and baseline characteristics are important determinants of outcome alone or in combination with modality., (© 2021 Wiley Periodicals LLC.)

Objective: Latinx young adults in college (ages 18-25 years) are at a heightened risk for health disparities and there is a need to understand individual-based characteristics that are related to such health inequalities including anxiety, depression, and sleep disturbances. The cross-sectional current study investigated the role of worry in relation to anxious arousal, social anxiety, general depression, and insomnia among Latinx college students. Participants/Method: Participants included 401 ( M age = 21 years; SD =2.01; 83% female) Latinx students at a large, southwestern university. Results: Results indicated that greater levels of worry were related to increased levels of anxious arousal, social anxiety, general depression, and insomnia. These findings were evident above and beyond variance accounted for by age, sex, and subjective social status. Conclusions: The current investigation suggests that elevated levels of worry among Latinx young adults may be associated with greater levels of anxiety, depression, and insomnia.

Cigarette smoking is a known risk factor for severe disease and death from respiratory infection. Initial data suggest that smoking is a risk factor for COVID-19 symptom severity. Exposure to increased pandemic-related stress and subsequent worry about COVID-19 may amplify the desire to smoke to down-regulate distress. The present investigation sought to test this conceptual model by evaluating worry about COVID-19 in relation to COVID-19 coping motives for smoking, perceived barriers for smoking cessation, and smoking abstinence expectancies. Participants were 219 daily combustible cigarette smokers (55.70% female, M age  =  41.43 years, SD  = 11.06). Six separate, two-step hierarchical linear regression models were conducted for each of the criterion variables. As expected, worry about COVID-19 was significantly and positively related to COVID-19 coping motives for smoking and perceived barriers for smoking cessation. Worry about COVID-19 also was a positively significant predictor of smoking abstinence expectancies of negative mood, somatic symptoms, and harmful consequences, but not positive consequences. The present study provides novel empirical evidence that worry about COVID-19 is related to key cognitive-affective smoking processes beyond the effects of age, sex, race, ethnicity, COVID-19 exposure, smoking rate, e-cigarette use status, and anxiety symptoms. These results highlight the potential utility in assessing level of worry about COVID-19, a transdiagnostic construct, among combustible cigarette smokers to better understand cognitive-affective factors that may maintain smoking behavior in the context of the COVID-19 pandemic.

This study aimed to evaluate the performance of the point-of-care circulating cathodic antigen (POC-CCA) test in a highly endemic area in Brazil, comparing it to the Kato-Katz (KK) technique for sensitivity, specificity and the intensity of the reaction of the test in relation to the parasitic load. The community in Sergipe, Brazil, participated in the study, providing three stool samples, one of urine (POC-CCA) and fingers tick blood sample was tested by enzyme-linked immunosorbent assay (ELISA). Sensitivity, specificity, positive predictive value, negative predictive value, accuracy, kappa coefficient and Spearman's correlation were calculated for the POC-CCA test using the KK as the reference. The prevalence of schistosomiasis by KK testing was 48.82%; POC-CCA (t+) 66.14%; POC-CCA (t-) 45.24%. ELISA results showed 100% agreement in individuals with high and moderate eggs per gram (EPG). POC-CCA presented good diagnostic performance in individuals with medium and high EPG, but there were a high number of false negatives in individuals with low intensity infections. As observed, POC-CCA-filter test improves accuracy and sensitivity compared to a conventional test.

Latinx individuals demonstrate significant pain-related health disparities compared to other racial/ethnic groups. Moreover, young adulthood (18-25 years of age) is a primary developmental window wherein pain-related health problems are first encountered and may be related to more severe somatic and mental health symptoms. Pain-related anxiety may be one mechanistic construct linking individual differences in the experience of pain intensity to poorer somatic experiences and mental health among Latinx young adults. Thus, the current study examined pain-related anxiety as an explanatory factor underlying the relationship between pain intensity and body vigilance, perceptions of health, worry, anxious arousal, and depressive symptoms among Latinx young adults. Participants included 401 Latinx young adults ( M age  = 21 years; SD  = 2.02; age range: 18-25 years; 83% female) at a large, southwestern university. Results revealed that individual differences in pain intensity had a significant indirect effect on the studied somatic and negative affect variables through pain-related anxiety. These novel findings suggest future work should continue to explore pain-related anxiety in the association between the experience of pain and somatic and mental health among Latinx young adults.

Individual differences in interpretation biases-the tendency to interpret ambiguous stimuli as threatening-partially explain the presence of comorbid depressive symptoms among anxious youth. Increasing efforts have examined physiological processes that influence the association between interpretation biases and depressive symptoms in this population, and potential gender differences in this relationship. This study examined the moderating role of respiratory sinus arrhythmia (RSA) suppression (i.e., decrease from baseline)-an index of parasympathetic nervous system reactivity-in the association between interpretation biases and depressive symptoms in clinically anxious youth. One-hundred-and-five clinically anxious children (M age  = 10.09 years, SD = 1.22; 56.7% female; 61.9% racial/ethnic minority) completed measures of self-reported and behaviorally indexed interpretation biases, reported anxiety/depression symptom severity, and participated in a speech task. RSA suppression during the task moderated the association between interpretation biases and depressive symptom severity in the total sample. Separate exploratory moderation analyses were conducted among girls and boys. Among girls, RSA suppression moderated the association between behaviorally indexed interpretation biases and depressive symptoms, and marginally moderated (p = .067) the association between self-reported interpretation biases and depressive symptoms. Among boys, RSA suppression was not a significant moderator. These findings may help identify clinically anxious youth most at-risk for comorbid depressive symptoms., (© 2020 Wiley Periodicals LLC.)

Anxiety sensitivity-the fear that anxiety-related sensations will result in catastrophic physical, social, or psychological consequences-is a robust risk factor for clinical anxiety. However, less is known about how anxiety sensitivity may interact with physiological modulation of arousal to predict anxious children's fear responses. The present investigation examined vagal withdrawal as a moderator of the association between anxiety sensitivity and anxious children's ability to downregulate subjective feelings of fear in response to an anxiety-provoking speech task. Observer ratings of anxious behaviors and performance during the task were also examined. It was hypothesized that children's anxiety sensitivity levels would interact with respiratory sinus arrhythmia (RSA) suppression to explain unique variance in subjective fear downregulation, anxious behaviors, and task performance. Participants were 105 children with anxiety disorders (N = 105; M = 10.07 years, SD = 1.22; 57% female) who completed diagnostic interviews, questionnaires, a speech about their family, and an RSA assessment in baseline and speech conditions. Interactions between RSA suppression and anxiety sensitivity predicted unique variance in subjective fear downregulation. Specifically, the greatest difficulties downregulating subjective fear responses were exhibited by children with high anxiety sensitivity and low RSA suppression. Interactions between RSA suppression and anxiety sensitivity did not predict variance in observer ratings of anxious behaviors or task performance. However, higher baseline RSA and speech RSA were significantly associated with fewer anxious behaviors during the speech. Higher baseline RSA was also significantly associated with better speech performance. These findings highlight the importance of vagal withdrawal and its interaction with anxiety sensitivity in predicting downregulation of subjective fear among clinically anxious children.

In the present work, gold nanoparticles were synthesized through a green route by using, for the first time, polysaccharides extracted from pineapple gum (PG) as the reducing and capping agent. The obtained nanoparticles (AuNPs-PG) were characterized by UV-VIS, FTIR, TEM, FESEM, EDX, XRD, and zeta potential measurements, which confirmed that PG was effective to produce AuNPs with an average diameter of 10.3 ± 1.6 nm. The AuNPs-PG were employed as the modifier of glassy carbon paste electrodes (CPE/AuNPs-PG), which were applied as sensitive electrochemical sensors to the determination of the antihistamine drug promethazine hydrochloride (PMZ). Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements showed that the AuNPs-PG could enhance the electronic transfer properties of the glassy carbon paste, which was due to their large surface area and high electrical conductivity. After optimization of the instrumental parameters of square wave voltammetry (SWV) through a Box-Behnken factorial design, a linear relationship between the anodic peak current and PMZ concentration was obtained in the range from 2.0 to 15.7 μmol L -1 in McIlvaine buffer solution pH 5.0. The detection and quantification limits were found to be equal to 1.33 and 4.44 μmol L -1 , respectively. The developed sensors could successfully quantify PMZ in different commercial pharmaceutical formulations, with satisfactory levels of accuracy and precision. In addition to improving the analytical features of the electrodes, hemocompatibility assays carried out on erythrocytes and leukocytes showed that the AuNPs-PG do not exhibit toxic effects on the referred cells. This interesting behavior enables their use in biocompatible electrochemical sensing platforms as well as for future biomedical investigations., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Introduction: Accumulating evidence demonstrates a strong link between alcohol consumption and smoking status among Latinx individuals. However, there is a need to evaluate the cognitive processes and experiences related to quitting smoking among Latinx smokers. The purpose of the current paper was to examine the association between alcohol consumption and smoking expectancies, barriers to cessation, cigarette dependence, quit problems, and intentions and confidence to quit., Methods: Data were taken from a sample of Spanish-speaking Latinx daily smokers (N = 359; 59% female; M age  = 33.20, SD = 9.71) who completed an online survey. The alcohol consumption subscale of the Alcohol Use Disorders Identification Test (AUDIT; Babor, Higgins-Biddle, Saunders, & Monteiro, & World Health Organization, 2001) was used to predict smoking variables., Results: Consistent with our prediction, alcohol consumption significantly predicted smoking variables indicative of poorer smoking cessation ability. Specifically, greater alcohol consumption was associated with greater positive and negative smoking expectancies, barriers to cessation, and quit problems experienced during prior cessation attempts. Unexpectedly, greater alcohol consumption was also associated with greater confidence to quit smoking., Conclusions: The current research suggests that alcohol consumption should be considered in the context of smoking cessation among Latinx individuals. The findings confirm and extend previous research by demonstrating that alcohol consumption is associated with proximal predictors of smoking outcomes that can be targeted during treatment. Implications for future research include addressing alcohol consumption during intervention and treatment of Latinx daily smokers., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Background: The additive effect of experiencing chronic pain in the context of nicotine addiction places smokers with chronic pain at elevated risk for experiencing physical and mental health problems. Isolating factors that explain linkages between pain and health-related outcomes among smokers with chronic pain is an important next step. Therefore, the current study examined the explanatory role of anxiety sensitivity in relations between pain intensity and current opioid misuse, severity of opioid dependence, tobacco-related problems, and anxiety/depressive symptoms., Method: Participants were 187 (M age  = 39.02, SD = 9.94, 74.9% female) daily smokers with chronic pain who completed a battery of self-report measures on pain experience, anxiety sensitivity, tobacco and opioid use, and anxiety/depression symptoms. Indirect effect analyses were conducted to examine anxiety sensitivity as a mediator of the relations between pain intensity and health-related outcomes., Results: A significant indirect effect emerged for pain intensity, through anxiety sensitivity, on opioid misuse (ab = 0.83, SE = 0.24, 95% CI [0.39, 1.34], CSE = 0.17), severity of opioid dependence (ab = 0.17, SE = 0.05, 95% CI [0.08, 0.26], CSE = 0.16), tobacco use problems (ab = 0.16, SE = 0.06, 95% CI [0.07, 0.28], CSE = 0.11), and anxiety/depressive symptoms (ab = 0.20, SE = 0.06, 95% CI [0.10, 0.31], CSE = 0.19)., Conclusion: The current investigation highlights the potential importance of anxiety sensitivity in terms of the experience of pain with severity of substance use and anxiety/depressive symptoms among smokers with chronic pain.

The United States (US) population consumes an estimated 68% of the world's prescribed opioids each year, and over 2 million adults in the US suffer from an opioid use disorder. Although chronic pain populations are among the highest risk segments of the general population for opioid misuse and dependence, there is little understanding of individual risk characteristics that may contribute to greater risk for these outcomes among this group. The present investigation explored the concurrent role of anxiety sensitivity and pain intensity and their interaction in relation to opioid misuse and dependence among 429 adults with chronic pain (73.9% female, M age  = 38.32 years, SD = 11.07). Results revealed that both anxiety sensitivity and pain intensity were associated with opioid misuse and dependence. There was no evidence of an interaction for either outcome. Post-hoc analyses indicated that of the lower-order anxiety sensitivity facets, physical and mental incapacitation concerns contributed to variance in opioid misuse and only mental incapacitation concerns contributed to variance in opioid dependence. Overall, the current findings suggest the importance of assessing anxiety sensitivity in screening for opioid-related problems among persons with chronic pain, as it may represent a distinct pathway to poorer opioid-related outcomes among this group., (Copyright © 2020.

In the present work, the green synthesis of silver nanoparticles (AgNPs) using the sulfated polysaccharide porphyran (PFR) as capping agent and d-glucose as reducing agent is described. PFR was extracted from red seaweed and characterized by employing 13 C NMR and determination of total sugar, protein, and sulfate contents. The obtained AgNPs-PFR were characterized by using UV-VIS spectroscopy, zeta potential determination, FESEM, and TEM, which demonstrated that PFR was effective at capping the AgNPs, yielding stable suspensions. The AgNPs-PFR presented good antimicrobial properties against Gram-positive and Gram-negative bacterial strains (Staphylococcus aureus and Escherichia coli, respectively). The AgNPs-PFR were also employed as the modifier of carbon paste electrodes, which were efficiently applied as electrochemical sensors for the determination of 5-fluorouracil (5-FU), an important anticancer drug, through square wave voltammetry (SWV). The AgNPs-PFR improved the electrochemical properties of the electrodes, and enhanced their electroanalytical performance. The developed sensing device presented detection and quantification limits equal to 10.7 and 35.8 μmol L-1, respectively, towards 5-FU determination. The proposed electrochemical sensor successfully quantified 5-FU in a real pharmaceutical formulation, confirming its potential as a new promising analytical detection tool for 5-FU quality control purposes., (Copyright © 2020 Elsevier Ltd.

Background: Obesity and chronic low back pain often co-occur and are associated with psychosocial and physical impairments such as weight-related impairment and fatigue. Yet, there is little understanding of psychological factors that may be associated with weight-related impairment and fatigue (a psychosocial factor) among this vulnerable population., Methods: Thus, the current study examined the role of anxiety sensitivity as it relates to self-reported weight-related impairment and fatigue severity among persons with obesity and chronic low back pain. Participants included a nationally representative sample of adults (N = 616) with co-occurring obesity and chronic low back pain (77.3% female, M age = 45.9 years, SD = 11.53)., Results: Results revealed that anxiety sensitivity was associated with greater levels of weight-related impairment and fatigue severity after controlling for age, sex, body mass index (BMI), pain interference, and perceived general health., Conclusions: The findings suggest that anxiety sensitivity may be a mechanistic target for better understanding and addressing weight-related impairment and fatigue severity among individuals with obesity and chronic low back pain.

Objectives: The opioid epidemic is a significant public health problem largely driven by opioid prescriptions for chronic pain. Among those with chronic pain, anxiety and depressive symptoms have been linked to opioid misuse, and individual differences in anxiety and depressive symptoms among adults with chronic pain may be important for better understanding pain. Yet, little work has examined mechanisms that may link anxiety and depressive symptoms to opioid misuse among adults with chronic pain. Anxiety sensitivity (AS), or the fear of anxiety-related physical sensations, may be one candidate construct that has been linked independently to anxiety and depressive symptoms as well as opioid misuse., Methods: The current survey-based study examined the indirect association of AS in the relation between anxiety and depressive symptoms and opioid misuse among 429 adults with chronic pain currently using prescription opioid medication (73.9% female, Mage=38.32 y, SD=11.07)., Results: Using structural equation modeling, it appears that AS is a potential construct in the interrelation between anxiety and depressive symptoms and opioid misuse. However, an alternative model found equally strong empirical support, as mental health symptoms may serve as an explanatory factor between AS and opioid misuse., Discussion: Bi-directional effects are apt to be involved among the studied variables. Prospective research is needed to replicate the study results and isolate the temporal patterning between the studied constructs. Nonetheless, the data overall highlight the importance of both AS and anxiety and depressive symptoms in terms of understanding opioid misuse among adults with chronic pain.

The present study examined the underlying role of anxiety sensitivity in the association between effortful control and anxiety and depressive symptoms in a sample of clinically anxious children. It was hypothesized that effortful control would exert an indirect effect through anxiety sensitivity in relation to child anxiety and depressive symptoms. Clinically anxious children ( N = 105; M age  = 10.09 years, SD  = 1.22; 56.7% female; 61% ethnic minority) and their mothers completed a diagnostic interview and a battery of questionnaires that included self- and mother-ratings of child effortful control, anxiety sensitivity, and anxiety and depressive symptoms. The indirect effect of effortful control via anxiety sensitivity on child anxiety and depressive symptoms was significant across child- and mother-completed measures. Among clinically anxious youth, greater effortful control was related to lower anxiety sensitivity, which was related to lower anxiety and depressive symptoms. Future work should evaluate whether targeting effortful control leads to clinically meaningful reductions in anxiety sensitivity and child anxiety and depressive symptoms.
