Abstract:
Substance use occurs on college campuses nationwide and is among the top threats to college-student health. The present study aimed to explore the impact of stress on substance use attitudes. The independent variable was acute psychosocial stress, induced using the Trier Social Stress Test. We measured chronic stress using the Adverse Childhood Experiences questionnaire. The Alcohol Purchase Task (i.e., alcohol demand, alcohol breakpoint, alcohol expenditure) and the Cognitive Appraisal of Risky Events-Revised questionnaire (i.e., expected involvement with substances and expected benefits and consequences of using substances) were the dependent variables. We predicted that participants who completed the acute stress task would report greater attitudes toward substance use behaviors and this would be more pronounced for those with higher levels of chronic stress. Acute stress did not affect willingness to pay for alcohol, F(3, 85) = 0.55, p = .65, ηp2 = 0.02, or expected positive or negative consequences from engaging in substance use, F(3, 85) = 0.44, p = .73, ηp2 = 0.02. There was a small positive association between chronic stress, as measured by adverse childhood experiences, and expected use, ρ(89) = .22, p = .04. In exploratory analyses, we found expected positive benefits of substance use to be significantly associated with expected future involvement, whereas expected negative consequences of substance use was associated with expected future involvement. Our results imply that acute and chronic stress were not significant in predicting substance use behaviors. Rather, those who expect benefits are more likely to use substances.

Abstract:
Introduction: the MMSE is used for eligibility screening of potential research participants diagnosed with substance use disorder (SUD), as abilities needed to provide a valid informed consent or accurate information could be impaired in these clinical populations. Knowledge about the capacity of the MMSE to detect impairment in these abilities or at least to assess impact of SUD on its total score, however, is rather diffuse. This has important ethical and methodological implications. Objective: to analyze effects of SUD only, main substances of abuse, age of onset of substance use, recent substance use, and psychiatric comorbidity upon MMSE outcome. The overall purpose of the study was to assess the utility of the MMSE for eligibility screening of potential research participants with SUD. Method: individuals were recruited from residential facilities for substance use treatment. A demographic questionnaire, MMSE and Mini International Neuropsychiatric Interview were used. Results: A total of 601 participants were gathered for main analysis. Controlling for education, no differences in MMSE score were detected within main substances of abuse (F=1.25[4,529], p=.28), nor between SUD only versus SUD with psychiatric comorbidity (F=.58[1,597], p=.44). Effects of age of onset and recent use of specific substances upon MMSE score were also absent. Discussion and conclusions: If there is some cognitive impairment in this clinical population, it may not be pertinently assessed by the MMSE, thus casting doubt on its pertinence for eligibility screening.

Abstract:
The plants Astragalus pterocephalus growing in Uzbekistan are a source of triterpene glycosides. The main triterpene glycoside, in terms of content, is a cycloartan glycoside – cyclosiversioside F. To obtain an individual biologically active compound cyclosiversioside F with 95% purity, a proposed method involves extraction with methanol, concentration and dilution with an equal volume of water, then followed by a sequential extraction from the aqueous extract with chloroform, ethyl acetate and butanol. Then a chromatographic separation of the purified amount of extractives on a column with silica gel, isolation of the substance and precipitation from a solvent system must be performed, followed by recrystallization and drying. The optimal conditions for the isolation and separation of the amount of extractive substances have been developed in order to obtain an individual glycoside. Cyclosiversioside F was authenticated by TLC in comparison with an authentic sample. Quantitative analysis of the glycoside was carried out by HPLC. The purity of cyclosiversioside F was confirmed by taking 1H and 13C NMR spectra.

Abstract:
How well does substance use predict adolescent recidivism? When the Cox proportional hazards model was applied to officially recorded first rearrest of 505 juvenile offenders, a best-fitting complex multivariate model indicated that: (a) parent reports that youths “often” use substances more than doubles first rearrest risk, (b) averaged youth and parent substance use reports predict recidivism better than a single source, (c) parent or youth denial of youth substance use predicts recidivism, (d) age at first arrest does not predict recidivism, (e) non-White/non-Asians have a 79% higher recidivism risk than peers, (f) parent-reported delinquency predicts recidivism with declining accuracy, and (g) substance use robustly predicts recidivism despite prior reported delinquency, gender, ethnicity, age, follow-up time, or data source. Findings are related to host-provocation theory.

Abstract:
IntroductionEarlier studies have shown that candidate gene risk polymorphisms and psychoactive substance abuse influence the frequency and severity of psychosis.ObjectivesIn this study we examined whether the most studied schizophrenia risk polymorphisms and psychoactive substance abuse interact in their influence on symptom severity and neurocognition.MethodsWe analyzed the clinical data of 280 schizophrenia patients, including genotyping data of the candidate genes NRG1, DTNBP1, RGS4, G72/G30 and PIP5K2A. Patients were assessed clinically by the Positive and Negative Symptom Scale (PANSS) and information about substance abuse was based on self-report and reviewing patient charts. We tested for possible interactional effects using the General Linear Model (GLM) analysis.Results15,8% of patients reported episodic or regular substance abuse, the vast majority (92%) used cannabis or the combination of cannabis and another drug. Substance abuse was associated with higher scores of the PANSS hostility/excitement factor, independent of sex, age, or genetic results (F = 4,02;p = 0,04). We found significant interactional effects of the DTNBP1 gene risk polymorphisms and substance abuse on different PANSS factors: rs2619528 and positive substance abuse interaction were associated with higher scores on the PANSS negative factor (F = 4,6;p = 0,03), and the PANSS depression factor (F = 4,75;p = 0,03). Moreover the rs3213207 - substance abuse interaction was associated with higher scores on the PANSS cognitive factor (F = 7,55;p = 0,006). Carriers of the Val allele of the COMT Val158Met polymorphism demonstrated significantly higher scores on the PANSS depression factor (F = 5,53;p = 0,02).ConclusionsOur results underscore the importance of gene-environment interactions in the phenotypic heterogeneity of schizophrenia.

Abstract:
Mental health disparities among transgender and gender diverse (TGD) populations have been documented. However, few studies have assessed differences in mental health symptom severity, substance use behavior severity, and engagement in care across TGD subgroups. Using data from the electronic health record of a community health center specializing in sexual and gender minority health, we compared the (1) severity of self-reported depression, anxiety, alcohol use, and other substance use symptoms; (2) likelihood of meeting clinical thresholds for these disorders; and (3) number of behavioral health and substance use appointments attended among cisgender, transgender, and non-binary patients. Participants were 29,988 patients aged ≥18 who attended a medical appointment between 2015 and 2018. Depression symptom severity (F = 200.6, p < .001), anxiety symptom severity (F = 102.8, p < .001), alcohol use (F = 58.8, p < .001), and substance use (F = 49.6, p < .001) differed significantly by gender. Relative to cisgender and transgender individuals, non-binary individuals are at elevated risk for depression, anxiety, and substance use disorders. Gender was also associated with differences in the number of behavioral health (χ2 = 51.5, p < .001) and substance use appointments (χ2 = 39.3, p < .001) attended. Engagement in treatment among certain gender groups is poor; cisgender women and non-binary patients assigned male at birth were the least likely to have attended a behavioral health appointment, whereas transgender men and cisgender women had attended the lowest number of substance use appointments. These data demonstrate the importance of (1) assessing gender diversity and (2) addressing the barriers that prevent TGD patients from receiving affirming care.

Abstract:
The chemical interaction of equivalent amounts of MF+NaBr (M – K, Rb, Cs) was studied by differential thermal and X-ray phase analysis. A mechanism of interaction during thermal activation is proposed, including the formation of NaF+MBr products at the contact boundaries of the initial substance grains due to the diffusion of Na+ and M+ followed by contact melting of four substances that form a labile liquid phase below or equal to the melting points of low-melting triple eutectics. The labile liquid occurrence in the sample promotes rapid ionic interaction. The heating curves of equivalent amounts of two substance powdered mixtures corresponding to the unstable diagonals of triple irreversibly reciprocal systems made it possible to obtain data on the appearance of the liquid phase, the onset of exothermic reactions (the melting points of low melting eutectics), the melting temperatures of quasibinary eutectics on stable diagonals, and the melting temperatures of the mixtures. The crystallization of molten mixtures of equivalent amounts of two unstable substances of triple irreversibly reciprocal systems made it possible to determine the liquidus temperature at the point of complete conversion and the temperature of the crossing point on a stable diagonal. Therefore, the heating and cooling curves analysis provides information on the melting points of low-melting triple eutectics (570, 508 and 430 °C), the temperatures of the pass points (654, 644 and 606 °С) and the melting temperatures of the compositions corresponding to the full conversion points (798, 845 and ~840 °C) in the Na+,K+||F–,Br–, Na+,Rb+||F–,Br–, and Na+,Cs+||F–,Br– systems, respectively. Powdered substances exchange reactions can be used as low-potential exothermic compounds, as fuses, which turn off various reactors or plants when the liquid phase appears, and for the synthesis of inorganic substances.

Abstract:
AbstractThe common materialist view that a functional account of intentionality will eventually be produced is rejected, as is the notion that intentional states are multiply realisable. It is argued also that, contrary to what many materialists have held, the causation of behaviour by intentional states rules out the possibility of a complete explanation of human behaviour in physical terms, and that this points to substance dualism. Kant's criticism of the Cartesian self as a substance, endorsed by P. F. Strawson, rests on a misinterpretation of Descartes. The so-called ‘causal pairing problem’, which Kim sees to be the crucial objection to substance dualism, is examined, and Kim's arguments are rejected.

Abstract:
During the first phases of adolescent development, young people have little self-efficacy and resistance against substance use. The aim of this study was to demonstrate the effectiveness of role-playing scenarios on the self-efficacy of students in resisting substance use. A pre test and post test study design was used with a single group. The study was carried out with 245 secondary school students. The scenario-based training, developed by the researchers, was presented by the school counselors once a week for 4 weeks. For this purpose, a booklet of scenarios was prepared for the teachers. The role-playing scenarios were intended to improve adolescents’ abilities to say “no” to substance offers, to prevent them from becoming addicted to certain substances, and to call for help if needed. The data of the study were collected using the Personal Information Form and the Self-Efficacy for Adolescences Protecting Substance Abuse Scale . The obtained data were assessed using percentages, chi-square, t test, and F test in the SPSS software. Results showed that, after the training, the mean score in the Self-Efficacy for Adolescences Protecting Substance Abuse Scale increased significantly (103.20 ± 20.00) compared with before the training (92.11 ± 17.08) ( P < .05). Short-term outcomes of the class-based scenario training were observed to be effective in the development of students’ self-efficacy to resist the temptations of substance use.

Abstract:
As a part of sustainable product design, design for disassembly is critical for maintaining competitiveness of manufacturers. The conflicts between disassembly capability and functionality and reliability need to be addressed innovatively and effectively. This article proposes a method to combine functional analysis and substance-field(S-F) analysis adapted from TRIZ to solve such complex conflicts. First, problems of current design that hinder the disassembly capability of products are identified. Second, functional and cause analysis are carried out for the technical system to transform conceptual description into practical description for components in the technical system. Last, a solution for improving the disassembly capability of products is proposed based on the structural model obtained from S-F analysis. This method is used to improve the disassembly capability of couplings in automotive transmissions, and proven to be effective and feasible in discovering an innovative solution.

Abstract:
Abstract Introduction The purpose of the current study was to examine the relationship between current beliefs about hypnotic medications and historical use of prescription hypnotic medications or non-prescription substances for sleep (i.e., over the counter [OTC] medications, alcohol, and cannabis). Methods Participants were 142 middle age and older adults with insomnia (M age = 62.9 [SD = 8.1]; 71.1% female) enrolled in the RCT of the Effectiveness of Stepped-Care Sleep Therapy In General Practice (RESTING) study. Participants reported on history of substances they have tried for insomnia and completed the Beliefs about Medications Questionnaire-Specific with two subscales assessing beliefs about 1) the necessity for hypnotics, and 2) concerns about potential adverse consequences of hypnotics. Participants were grouped based on whether they had used no substances for sleep (No Subs, 11.6%), only prescription medications (Rx Only, 9.5%), only non-prescription substances (NonRx Only, 26.6%), or both prescription and non-prescription substances (Both, 52.3%). Results Sixty-one percent of the sample had used prescription medication for sleep and 79% had used non-prescription substances (74% OTC medication, 23% alcohol, 34% cannabis). The greater number of historical substances endorsed, the stronger the beliefs about necessity of hypnotics, F(1,140)=23.3, p&lt;.001, but not about concerns. Substance groups differed significantly on necessity beliefs, F(3,1)=10.68, p&lt;.001; post-hocs revealed the Both group had stronger beliefs than the No and NonRx Only groups. Substance groups also differed significantly on the concerns subscale, F(3,1)=6.68, p&lt;.001; post-hocs revealed the NonRx Only group had stronger harm beliefs than the other three groups. Conclusion The majority of the sample had used both prescription and non-prescription substances to treat insomnia. Historical use of substances for treating insomnia was associated with current beliefs about hypnotics. Individuals who had used both prescription and non-prescription substances for sleep in the past had stronger beliefs about needing hypnotics to sleep at present, which may reflect a pattern of multiple treatment failures. Individuals who had only tried non-prescription substances for sleep may have specifically sought alternative substances due to concerns about using hypnotics. Future research should seek to understand the impact of treatment history on engagement in and benefit from non-medication-based treatment for insomnia.

Abstract:
Biological activity of water soluble fractions F-1 and F-2, which were extracted from hop, was studied and its action mechanism was speculated using the immature female sd rats. Administration of the substance significantly inhibited the effects of pregnant mare serum gonadotropin (PMSG) on 22-day-old female rats. Thus, PMSG-induced increases in ovarian weight, estrogen secretion, number of ovulated egg, progesterone production, uterine thymidine kinase activity, and plasma LH level were suppressed significantly. Furthermore, addition of the substance to incubated ovarian cells of the second day after PMSG injection resulted in suppression of FSH-induced estradiol secretion in vitro, probably via cAMP-dependent mechanism. But addition of the substance to incubated pituitary cells from ovariectomized rats did not change in LH secretion.

Design/methodology/approach A rationale for the development of two new domains (Domain 7, substance use and Domain 8, independent living skills) and preliminary data supporting the use of the ASAM CriteriaTM as a placement process for all types of behavioral health issues will be provided. Findings Dimension 3 and Domains 7 and 8 were correlated with selected clinical indices in the expected direction (Dimension 3: depression (F (4, 4650)=202.092, p<0.001), medication usage (F (4, 4,637)=174.254, p<0.001), and psychotic symptoms (F (4, 4,561)=62.954, p<0.001); Domain 7: alcohol use (F (4, 4,458)=213.786, p<0.001) and drug use (F (4, 4,471)=611.491, p<0.001); and Domain 8: functional impairment (F (4, 3,927)=815.646, p<0.001) and number of “high needs” (F (4, 3,927)=737.568, p<0.001). Research limitations/implications The limitations of this research included a lack of inter-rater reliability data and less established intake assessments. Practical implications This single placement approach for clients seeking behavioral health services can create a more efficient, person-centered intake experience. Originality/value This paper suggests that it is possible to deploy a single assessment and placement approach for all types of behavioral health issues.

Abstract:
BACKGROUND: Investigators have proposed that the cognitive-bebavioral patterns of persons with the dual diagnoses of depression and substance abuse differ from those of persons with only one of the disorders. However, researchers have not investi gated these differences. OBJECTIVE: This study examined differences in severity of depression, cognitions, and adaptive functioning among depressed persons with and without coexisting substance abuse. DESIGN: A cross-sectional design was used to compare depressed adult inpatients with (n = 31) and without (n = 32) coexisting substance abuse. RESULTS: Although both groups were found to be moderately depressed and limited in their functional ability, the dual diagnosis group was more severely depressed (F(1,60) = 4.05; p = .05), more limited in functioning (F(1,60) = 3.52; p = .07), and reported more depressive cognitions (F(1,60) = 7. 72; p =.01). The groups were similar in se verity of depression and adaptive functioning when the effects related to the depres sive cognitions were statistically controlled. CONCLUSION: The findings support the importance of using nursing interventions that involve cognitive restructuring to assist persons with the dual diagnoses of depressive illness and substance abuse to change their maladaptive ways of thinking to more healthy and adaptive thought processes.

Abstract:
Substance use disorders refers to the abuse of alcohol, illicit drugs, or substances such as over-thecounter medicines, medicines from unsupervised ordinary retail purchase, or even through prescription. It causes significant health problems and functional impairments such as disability and failure to meet responsibilities at work, school, or home. Common substance use disorders are use of alcohol, tobacco, cannabis (marijuana), stimulants, hallucinogens, sedatives, hypnotics, opioids, etc. Objective: To assess prevalence of substance use disorders and effectiveness of educational package on spreading knowledge about substance use disorders among adolescents in selected schools in Lekhnath, Nepal. Methodology: Pre experimental one group pretest and posttest design was used for the study. Non-probability convenience sampling technique was adopted for sampling. For the study, total of 155 adolescents studying in classes 9 and 10 were selected from schools in Lekhnath, Nepal. Self administered structured questionnaire was used to collect data. Data obtained were entered in Microsoft Excel and analyzed using statistical tool SPSS 16.0.  Result: Among 155 adolescents, 97.40% had heard of substance use disorders. 62.24% of people received the information about substance use disorders via mass media. Family members of 16.8% of samples were engaged in some kind of substance use disorders. 1.90% of sample students drank alcohol, who all happened to be male of age 15-16 years age group. In pretest, more than half (69.70%) of the adolescents had inadequate knowledge about substance use disorders. On the other hand, in the posttest, more than one third of adolescents (37.4%) had adequate knowledge and less than twothird adolescents (58.1%) had moderate knowledge on substance use disorders. The paired ‘t’ test was found to be significant on knowledge level (t=23.76 at 1% level).Only caste/ethnicity of demographical variable was found to be associated with pretest knowledge regarding substance use disorders (F= 3.495 at 5% level, p=0.033). Conclusion: The study concluded that adolescents are in great risk for substance use disorders. After educating on substance use disorders, adolescents gained adequate knowledge regarding the disorder. Study supports that educational package was effective in improving the level of knowledge regarding substance use disorders among adolescents

Abstract:
Background. Prevention of substance use disorder (SUD) is impeded by the large number, complexity and idiosyncratic configuration of etiological factors. Effective prevention of SUD is feasible however when intervention resources are prioritized to individuals who are objectively determined high risk and tailored to their specific characteristics and circumstances.Objective. This study had the aim of developing a rapid accurate screening instrument for determining current presence of and future risk for SUD. Methods. The sample consisted of 182 girls recruited when they were 10-12 years of age and tracked to 22 years of age. From a large item pool the Drug Use Screening Inventory Quick Screen for Females (DQS-F) was derived consisting of the Substance Involvement Index and the Problem Severity Index.Results. The DQS for Females (DQS-F) has high sensitivity for identifying girls who currently qualify for SUD diagnosis. Furthermore, accuracy of predicting future SUD with the DQS-F is in the good range at age 16 and in the very good range at age 19.Conclusions. Requiring only three minutes for administration on the Web the DQS-F is an efficient method for identifying girls requiring thorough assessment prior to implementing individualized intervention.

Abstract:
Lactobacillus plantarum BF001 isolated from chilled processed channel catfish produced an antimicrobial substance active against selected bacteria from the genera Lactobacillus, Lactococcus, Listeria, Micrococcus, Leuconostocs, Pediococcus, Staphylococcus, Streptococcus, Salmonella and Pseudomonas. The antimicrobial effect did not result from acidic fermentation products or hydrogen peroxide. Culture extracts showed a bactericidal mode of action, displayed optimal activity at pH 3.5, and retained full activity after 30 min at 100°C (pH 3.5). It was not conclusively proved that the substance, named plantaricin F, was sensitive to proteolytic enzymes. Its molecular weight was estimated by ultrafiltration studies to be under 10,000 daltons. The ability of plantaricin F to inhibit a wide-range of bacteria, including gram-positive and gram-negative foodborne pathogens, is of potential interest for food safety, and plantaricin F may have future applications as a food preservative.

Abstract:
Problem solving is lauded as beneficial, but students do not all learn well by solving problems. Using the resources framework, Tuminaro J., and Redish E. F., (2007), Elements of a cognitive model of physics problem solving: Epistemic games,Physical Review Special Topics-Physics Education Research,3(2), 020101 suggested that, for physics students, this puzzle may be partially understood by paying attention to underlying epistemological assumptions that constrain the approaches students take to solving problems while working on them. They developed an approach to characterizing epistemic games, which are context-sensitive knowledge elements concerning the nature of knowledge, knowing and learning. As there is evidence that context-activated knowledge influences problem solving by students in chemistry, we explored identifying epistemic games in students’ problem solving in chemistry. We interviewed 52 students spanning six courses from grade 8 through fourth-year university, each solving 4 problems. Using 16 contexts with substance characterization problems, we identified 5 epistemic games with ontological and structural stability that exist in two larger epistemological frames. All of these epistemic games are present at all educational levels, but some appear to grow in across educational levels as others recede. Some games also take lesser and greater precedence depending on the problem and the chemistry course in which students are enrolled and the context of the problem. We analyze these results through a frame of learning progressions, paying attention to students’ ideas and how these ideas are contextualized. Based on this analysis, we propose teaching acts that instructors may use to leverage the natural progressions of how students appear to grow in their capacity to solve problems.

Abstract:
Dopamine is synthesized within the kidney and dopamine 1 (DA1) receptors are associated with the proximal tubule. In pharmacological doses, dopamine increases renal blood flow and sodium excretion. It is possible that dopamine formed intrarenally acts locally via renal dopamine receptors to control renal function. We investigated the possible paracrine action of renal dopamine by intrarenal administration of a specific DA1 antagonist, Sch 23390, in doses confined to the kidney in conscious uninephrectomized dogs (n = 5) in metabolic balance at a sodium intake of 40 meq/day. Changes (mean +/- SE) in renal excretory and hemodynamic function in response to cumulative infusions of several doses of Sch 23390 (0.01, 0.1, 1.0, 5.0, and 10.0 pmol.kg-1.min-1) were studied. Sch 23390 at 0.01 pmol.kg-1.min-1 did not cause any changes in urinary flow rate or sodium excretion. Sch 23390 in doses from 0.1 to 10.0 mol.kg-1.min-1 caused a significant dose-dependent antidiuresis (F = 44.9, P less than 0.0001) and antinatriuresis (F = 42.1, P less than 0.0001) and a decrease in fractional sodium excretion (F = 44.2, P less than 0.0001). No changes in estimated renal plasma flow, glomerular filtration rate, plasma aldosterone concentration, plasma renin activity, or systemic arterial pressure occurred with any dose of intrarenal Sch 23390 infused into the renal artery. Rebound diuresis and natriuresis occurred after cessation of the DA1 blockade.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract:
7-Amino-4-methylcoumarin-3-acetic acid (AMCA) has been found to be a useful fluorophore for immunofluorescence. The present study describes a spectrophotometric method for determining the ratio of moles AMCA to moles protein (or the f/p ratio) in an AMCA-conjugated IgG. The concentration of a substance absorbing light can be determined spectrophotometrically using Beer's Law: Absorbance = Concentration x Extinction coefficient. From Beer's law, one can derive the following formula for determining the f/p ratio of AMCA-IgG conjugates: f/p = (epsilon 280IgG).A350 - (epsilon 350IgG).A280/(epsilon 350AMCA).A280 - (epsilon 280AMCA).A350 where A is the optical density of the conjugate at the given wavelength and epsilon is the extinction coefficient of a substance at the wavelength specified. Using conjugates of model proteins, it was found that the extinction coefficients of the AMCA moiety of AMCA-conjugated protein were 1.90 x 10(4) at 350 nm and 8.29 x 10(3) at 280 nm. Similarly, it was found that the extinction coefficients of swine IgG were 1.56 x 10(3) at 350 nm and 1.26 x 10(5) at 280 nm. Thus, for AMCA-conjugated swine IgG: f/p = (1.26 x 10(5)).A350 - (1.56 x 10(3)).A280/(1.47 x 10(4)).A280 - (6.42 x 10(3)).A350 [corrected]. Based on this formula, the f/p ratios of some AMCA-IgG conjugates useful for immunohistochemistry have been found to range between 6 and 24.

Abstract:
Trusting relationships between pregnant and postpartum women with substance use disorders (SUDs) and maternity nurses can improve health outcomes for women and their infants. This study was conducted to identify factors associated with the formation of trust in these nurse–patient relationships. Using a qualitative description approach, semi-structured interviews were conducted with 10 women who used substances during pregnancy and 15 maternity nurses. The narratives were analyzed with standard content analytic techniques. Findings revealed that six characteristics of nurses and five characteristics of women fostered or hindered the formation of trusting relationships. The characteristics of the maternity nurses were (a) interpersonal connections, (b) demeanor toward women, (c) ways of providing care, (d) approaches to providing information, (e) attitudes toward substance use, and (f) addiction expertise. The characteristics of the women were (a) engagement with nurses, (b) demeanor toward nurses, (c) attitudes toward care, (d) investment in recovery, and (e) ways of interacting with infant. The characteristics provide a framework by which maternity nurses can examine their attitudes and behaviors toward women with SUDs and inform the development of strategies to enhance their practice with this population.

Abstract:
IntroductionPolydrug abuse seems to be especially popular in Ibiza, an important market for new psychoactive substances (NPS). The misuse of psychoactive substances can lead to serious psychiatric symptoms.AimsTo evaluate symptoms induced by NPSs and other club drugs, correlating with the main classes of drugs.MethodsNinety subjects (M/F 59/31) admitted in the Psychiatric Unit of Can Misses Hospital (Ibiza) referring a recent intake of substances were enrolled. The following scales were administered: TLFB (Timeline follow-back); Positive and Negative Symptoms Scale (PANSS); Symptom checklist-90 (SCL-90) ; Young Mania Rating Scale (YMRS) ; Hamilton Depression Scale (HAM-D); Hamilton Anxiety Scale (HAM-A); Modified Overt Aggression Scale (MOAS); Columbia Suicide Severity Rating Scale (C-SSRS).ResultsPolydrug abuse was reported by 67.4% of the sample; the sample was grouped by the main preferred substance in THC-, stimulants-, and depressors-users. The majority of patients reported a previous psychiatric history. Positive symptoms resulted to be higher among THC-users (P < .05). Anxiety evaluated by SCL-90 was prevalent in the group of Depressors-users (P < .05). The scores of MOAS and SCL-90 subscale for hostility/aggression resulted to be significantly (P < .01) greater in the THC-users group.ConclusionsSome specific psychiatric symptoms are characteristic of some classes of substances and may help to identify them when a urine sample is not available. The possibility to develop psychiatric symptoms after a recent drug use is more common in two situations: (1) patients with a previous psychiatric history; (2) subjects with a history of very strong substance use.Disclosure of interestThe authors have not supplied their declaration of competing interest.
