Family history of substance use disorder and likelihood of prescription drug misuse in adults 50 and older.

OBJECTIVE: Individuals who are family history positive (FHP) for substance use problems have increased risk for substance use, substance use disorders (SUDs), and psychopathology. Links between FHP status and prescription drug misuse (PDM) have not been well investigated; this study examined PDM in adults 50 and older by FHP status. METHODS: Data were from the US NESARC-III (n = 14,667). Participants reported their opioid PDM, tranquilizer/sedative PDM, SUD, psychopathology, and family history status (i.e. first- and second-degree relatives with alcohol/substance use problems). Prevalence rates were estimated by FHP status, and logistic regressions compared FHP and family history negative (FHN) groups. RESULTS: FHP status was associated with significantly higher rates of PDM (e.g. past-year opioid PDM, FHP: 3.8%, FHN: 1.5%) and SUD from PDM (e.g. past-year SUD, FHP: 1.2%, FHN: 0.2%); also, prevalence varied by family history density, with the highest rates in those with three or more relatives with substance use problems (e.g. past-year opioid PDM: 5.5%). Overall, 32.2% of FHP individuals with past-year PDM had past-year co-occurring SUD and psychopathology diagnoses, versus 11.0% of FHN individuals. CONCLUSION: FHP status could inform treatment decisions in adults 50 and older with conditions for which prescription opioids or tranquilizer/sedatives are indicated.

Sources of prescription opioids and tranquilizers for misuse among U.S. young adults: differences between high school dropouts and graduates and associations with adverse outcomes.

Background and Objectives: Prior research has identified that sources of prescription drugs for misuse vary based on educational attainment, which is important as certain sources are associated with adverse outcomes. The current research addressed limitations of the extant literature by creating distinct categories of push factors for high school dropout (e.g., negative school performance/experiences), pull factors for high school dropout (e.g., starting a family or getting a job), and high school graduates who did not attend college.Methods: Using data from the 2009-2014 National Survey on Drug Use and Health, prevalence of sources were estimated and design-based multivariable logistic regression investigated the association between sources and educational attainment. Additionally, multivariable logistic regression assessed the associations between sources and adverse outcomes (i.e., substance use, substance use disorders, and mental health) separately for each educational category.Results: College respondents were more likely to report "physician" and free from "friend/relative" and less likely to report "purchased" as sources. For most educational categories, "purchasing" prescription drugs was associated with adverse outcomes. Additionally, "theft/fake" prescription emerged as a source associated with adverse outcomes for college respondents, while "friend/relative" was associated with adverse outcomes for high school graduates that did not go on to college.Conclusions: This research has important clinical implications as it identified young adults with a college education as being less likely to obtain prescription drugs from sources known to be associated with adverse outcomes. It also highlighted how associations between sources and adverse outcomes vary based on educational attainment.

Safety and effectiveness of olanzapine and droperidol for chemical restraint for non-consenting adults: a systematic review and meta-analysis.

BACKGROUND: Chemical restraint (CR) is emergency drug management for acute behavioural disturbances in people with mental illness, provided with the aim of rapid calming and de-escalating potentially dangerous situations. AIMS: To describe a systematic review of Randomised Controlled Trials (RCTs) reporting on short-term safety and effectiveness of drugs used for CR, administered to non-consenting adults with mental health conditions, who require emergency management of acute behavioural disturbances. A meta-analysis was conducted of those RCTs with comparable interventions, outcome measures and measurement timeframes. METHOD: Academic databases were searched for RCTs published between 1 January 1996 and 20th April 2020. Relevant RCTs were critically appraised using the 13-item JBI checklist. All RCTs were described, and step-wise filters were applied to identify studies suitable for meta-analysis. For these, forest and funnel plots were constructed, and Q and I2 statistics guided interpretation of pooled findings, tested using MedCalc Version 19.1. RESULTS: Of 23 relevant RCTs, 18 (78.2% total) had excellent methodological quality scores (at least 90%). Eight RCTs were potentially relevant for meta-analysis (six of excellent quality), reporting 20 drug arms in total. Adverse events for 6-36% patients were reported in all 20 drug arms. Four drug arms from two homogenous studies of N = 697 people were meta-analysed. These RCTs tested two antipsychotic drugs (droperidol, olanzapine) delivered intravenously in either 5 mgs or 10 mg doses, with outcomes of time to calm, percentage calm within five or 10 min, and adverse events. There were no significant differences between drug arms for either measure of calm. However, 5 mg olanzapine incurred significantly lower risk of adverse events than 10 mg olanzapine (OR 0.4 (95%CI 0.2-0.8)), although no dose differences were found for droperidol. CONCLUSION: 5 mg intravenous olanzapine is recommended for quick, safe emergency management of people with acute behavioural disturbances associated with mental illness.

Sex differences in nonmedical prescription tranquilizer and stimulant use trends among secondary school students in Argentina, Chile, and Uruguay.

BACKGROUND: Little is known about recent nonmedical prescription tranquilizer and stimulant use trends in Latin America. We tested whether recent trends among students in three South American countries differed by sex over time. METHODS: Three countries independently collected National School Students Survey on Drugs. Students in 8th, 10th, and 12th grades were sampled in Argentina (2007-2014, N = 328,202), Chile (2007-2015, N = 136,379), and Uruguay (2007-2016, N = 32,371). Weighted linear regression models predicted the prevalences and trends over time of past-year nonmedical tranquilizer and stimulant use by country, and tested whether trends differed by sex, adjusting for school type and grade. RESULTS: In Argentina from 2007 to 2014, past-year nonmedical prescription tranquilizer (girls: 2.8 to 2.6%, boys: 2.5 to 2.3%) and stimulant (girls: 1.7 to 1.3%, boys: 1.9 to 1.5%) use trends did not differ by sex. In Chile from 2007 to 2015, nonmedical prescription tranquilizer use trends significantly differed comparing girls (3.9 to 10%) with boys (3.2 to 6.9%); stimulant use trends did not differ comparing girls (1.6 to 2.0%) with boys (2.0 to 1.3%). In Uruguay from 2007 to 2014 and 2014-2016, past-year nonmedical prescription tranquilizer (girls: 5.1 to 6.6%; boys: 2.8 to 4.2%) and stimulant (girls: 1.8 to 0.7%; boys: 1.8 to 0.7%) use trends did not differ by sex. CONCLUSIONS: Trends of nonmedical prescription tranquilizer use recently increased in Chile and Uruguay, widening by sex over time in Chile only. The drivers of increasing tranquilizer use among girls in Chile and Uruguay merit further investigation.

Drug induced parkinsonism: Symptomatic beyond 22 months.

We report 2 cases of drug induced Parkinsonism followed longitudinally that remained symptomatic 22 and 27 months after stopping causative agents with normal dopamine ioflupane iodine-123 (DaT) single-photon emission computed tomography (SPECT) scans at 8 and 16 months.

A veterinary survey of factors associated with capture-related mortalities in cheetahs (Acinonyx jubatus).

The objective of this study was to gain better insight into factors associated with the capture-related mortality rate in cheetahs. A link to an online questionnaire was sent to zoo and wildlife veterinarians through the Species Survival Plan Programme and European Endangered Species Programme coordinators and via the 'Wildlife VetNet' Google group forum. The questionnaire consisted of 50 questions relating to the veterinarians' country of residence and experience, the medicine combinations used, standard monitoring procedures, capture-related complications and mortalities experienced in this species under different capture conditions. In addition, necropsy data from the national wildlife disease database of the National Zoological Gardens of South Africa were examined for cases where anaesthetic death was listed as the cause of death in cheetahs. A total of 75 veterinarians completed the survey, with 38 from African countries and a combined total of 37 from Europe, the United States (US) and Asia. Of these, 24% (n = 18/75) had experienced at least one capture-associated cheetah mortality, with almost all of the fatalities (29/30) reported by veterinarians working in Africa. A lack of anaesthetic monitoring and the absence of supplemental oxygen were shown to be significant risk factors for mortality. Hyperthermia, likely to be associated with capture stress, was the most common reported complication (35%). The results suggest that free-ranging rather than habituated captive cheetahs are particularly at risk of dying during immobilisation and transport. The capture-related fatalities in this species do not appear to be associated with either the veterinarian's level of clinical experience or the immobilisation agents used.

Prolactin, flupenthixol decanoate and first episode schizophrenia - clinical and laboratory correlates.

First-episode psychosis (FEP) patients are more sensitive to neuroleptic side-effects such as hyperprolactinemia. We examined the prolactin levels of previously minimally treated patients with first episode schizophrenia over their first year of treatment with flupenthixol decanoate and the relationship between prolactin levels, gender and clinical features of schizophrenia. Prolactin levels were assessed at three monthly intervals in 126 patients with first-episode schizophrenia in a single-site study conducted over 12 months during treatment with flupenthixol decanoate according to a fixed protocol. The mean prolactin level for the total sample was 11.91 ng/ml (standard deviation [SD]15.52) at baseline. Women had higher levels of prolactin than men at month 3, 6 and 12, reaching statistical significance at month 12 (p = 0.02). At 12 months more women than men had hyperprolactinemia (defined as more than 20 ng/ml for males, and as more than 25 ng/ml for females (p = 0.007). Using a mixed effect model, there was a significant association between prolactin change scores over 12 months and gender (p = 0.025) as well as Positive and Negative Syndrome Scale (PANSS) total scores (p = 0.001). In addition female gender (p = 0.04) and age (p = 0.02) correlated with the risk of hyperprolactinemia as categorical variable. In this study treatment with flupenthixol decanoate was associated with relatively low levels of hyperprolactinemia, likely owing to flupenthixol's relatively atypical mode of action, as well as to the low doses used in our study. We found an inverse correlation between total PANSS scores and prolactin levels, which could support the suggested theory of prolactin having antipsychotic properties. Our study confirms the importance of gender on the prolactin raising effects of antipsychotic treatment.

Prescription Tranquilizer/Sedative Sources for Misuse in Older Adults.

Background: Older adult prescription tranquilizer/sedative misuse is understudied, despite evidence of increased misuse prevalence and significant associated consequences (e.g., suicidal ideation). Identification of misuse sources could limit such misuse by offering policymakers and clinicians targets to limit diverted tranquilizer/sedative medication. Objective: To establish the prevalence of tranquilizer/sedative misuse sources in older adults and investigate associated poor outcomes. Methods: Data were from the 2009-14 National Survey on Drug Use and Health, including participants endorsing one or more past-month tranquilizer/sedative misuse sources (n = 3,162) with older adult (50-64 and 65 and older; n =160) tranquilizer/sedative source prevalence estimated and compared to younger cohorts. Results: Adults 65 and older had the greatest physician source use (38.2%) across ages. Physician source use in those 50 and older, relative to those obtaining medication from friends/family for free, was linked to a higher prevalence of both past-year prescription opioid misuse (58.6% versus 34.9%) and serious psychological distress (50.1% versus 11.6%). Conclusions/Importance: Physician source use is particularly prevalent in adults 65 and older, and adults 50 and older using physician sources appear at elevated risk of consequences. Careful monitoring of psychiatric symptoms in older adults receiving tranquilizers/sedatives appears warranted. Older adults use a unique pattern of tranquilizer/sedative misuse sources, as compared to younger groups, further signaling that older adult misuse processes differ from those in younger groups.

Trends in and correlates of tranquilizer misuse among adults who misuse opioids in the United States, 2002-2014.

PURPOSE: Almost a third of opioid overdose deaths also involve benzodiazepines, but few representative studies have examined misuse of benzodiazepines and other tranquilizers by adults who misuse opioids. This study estimated the prevalence and frequency of tranquilizer misuse among adults who misuse opioids and examined characteristics associated with tranquilizer misuse. METHODS: A sample of adults who misused opioids in the past year (n = 36,043) were identified in the National Surveys on Drug Use and Health 2002-2014. Tranquilizer misuse prevalence was estimated for each year from 2002 to 2014. Data were then pooled for all years. Multiple logistic and Poisson regression was used to identify characteristics independently associated with the prevalence and frequency tranquilizer misuse respectively. RESULTS: Twenty-eight percent of adults who misused illicit opioids in the past year also reported tranquilizer misuse. This prevalence did not change notably over the 13-year period examined. Among those who misused opioids, meeting criteria for opioid abuse or dependence was associated with a 134% increase in the odds of misusing tranquilizers during the same year. Other characteristics associated with increased odds of tranquilizer misuse included being aged 18-25 years, non-Hispanic white, uninsured, unemployed, and having used heroin. CONCLUSIONS: Tranquilizer misuse is common among adults who misuse opioids and has not changed substantially over the past decade. Meeting criteria for abuse or dependence of opioids is associated with more than double the odds of tranquilizer misuse among adults who misuse opioids.

Understanding women veterans' experiences with and management of weight gain from medications for serious mental illness: A qualitative study.

OBJECTIVE: More women veterans than men use Veterans Health Administration (VHA) mental health services. Some psychiatric medications are associated with weight gain and other metabolic side effects, with women more susceptible and reporting more distress than men. We sought to explore how women experience and manage medication-induced weight gain to identify strategies for improving its prevention and management in women. METHOD: We completed semistructured, qualitative interviews with 30 female veterans with serious mental illnesses prescribed antipsychotic or mood stabilizer medications and 18 mental health prescribers. Interview transcripts were summarized and coded via principles of phenomenological inquiry to develop themes reflecting the study purpose. RESULTS: We identified 5 themes related to females' experiences with medication-induced weight gain. Female veterans described considerable psychological and physical distress associated with weight gain. However, many expressed a willingness to accept weight gain as a trade-off for medications' therapeutic effects, a theme echoed by prescribers. Both described primarily using reactive rather than proactive or preventative weight management approaches and described the limited effectiveness of reactive approaches. Other contributing factors, including the multiple and uncertain causes of weight gain, uneven quality and quantity of weight loss information, lack of social support, and environmental barriers, add to the difficulty and complexity of their struggles. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: These findings improve our understanding of numerous veteran-, prescriber-, and environmental-level factors in the management of medication-associated weight gain in women that may be useful in designing gender-specific interventions.

Shifting characteristics of nonmedical prescription tranquilizer users in the United States, 2005-2014.

BACKGROUND: Benzodiazepine overdose rates have increased in the US, largely from concomitant use of other drugs such as opioids. Studies are needed to examine trends in prescription tranquilizer (e.g., benzodiazepine) use-with a particular focus on use of other drugs such as opioids-to continue to inform prevention efforts. METHODS: We conducted a secondary analysis of the 2005-2014 National Survey on Drug Use and Health, a repeated cross-sectional, nationally representative probability sample. Trends in past-year nonmedical tranquilizer use and trends in demographic and other past-year substance use characteristics among nonmedical users were examined (N = 560,099). RESULTS: Prevalence of nonmedical tranquilizer use remained stable from 2005/06 through 2013/14 at 2%. Prevalence of past-year heroin use and heroin use disorder both more than doubled among nonmedical tranquilizer users between 2005/06 and 2013/14 (Ps<.001). Nonmedical opioid use decreased between 2005/06 and 2013/14 (P < .001); however, opioid use disorder increased from 13.4% to 16.7% (P = .019). Prevalence doubled among those age >50 between 2005/06 and 2013/14 from 7.9% to 16.5% (P < .001), and nonmedical tranquilizer use among racial minorities also increased (Ps<.01). Prevalence of nonmedical use also increased among those with health insurance (P = .031), and this increase appeared to be driven by a 190.6% increase in nonmedical use among those with Medicare (from 2.6% to 7.4%; P = .002). CONCLUSIONS: Characteristics of nonmedical tranquilizer users are shifting, and many shifts are related to past-year nonmedical prescription opioid use and heroin use. Prevention needs to be geared in particular towards older individuals and to those who use opioids nonmedically.

Relative toxicity of mood stabilisers and antipsychotics: case fatality and fatal toxicity associated with self-poisoning.

BACKGROUND: Bipolar and other psychiatric disorders are associated with considerably increased risk of suicidal behaviour, which may include self-poisoning with medication used to treat the disorder. Therefore, choice of medication for treatment should include consideration of toxicity, especially for patients at risk. The aim of this study was to estimate the relative toxicity of specific drugs within two drug categories, antipsychotics and mood stabilizers, using large-scale databases to provide evidence that could assist clinicians in making decisions about prescribing, especially for patients at risk of suicidal behaviour. METHOD: Two indices were used to assess relative toxicity of mood stabilisers and antipsychotics: case fatality (the ratio between rates of fatal and non-fatal self-poisoning) and fatal toxicity (the ratio between rates of fatal self-poisoning and prescription). Mood stabilisers assessed included lithium [reference], sodium valproate, carbamazepine, and lamotrigine, while antipsychotics included chlorpromazine [reference], clozapine, olanzapine, quetiapine and risperidone. Fatal self-poisoning (suicide) data were provided by the Office for National Statistics (ONS), non-fatal self-poisoning data by the Multicentre Study of Self-harm in England, and information on prescriptions by the Clinical Practice Research Datalink. The primary analysis focussed on deaths due to a single drug. Cases where the drug of interest was listed as the likely primary toxic agent in multiple drug overdoses were also analysed. The study period was 2005-2012. RESULTS: There appeared to be little difference in toxicity between the mood stabilisers, except that based on case fatality where multiple drug poisonings were considered, carbamazepine was over twice as likely to result in death relative to lithium (OR 2.37 95% CI 1.16-4.85). Of the antipsychotics, clozapine was approximately18 times more likely to result in death when taken in overdose than chlorpromazine (single drug case fatality: OR 18.53 95% CI 8.69-39.52). Otherwise, only risperidone differed from chlorpromazine, being less toxic (OR 0.06 95% CI 0.01-0.47). CONCLUSIONS: There was little difference in toxicity of the individual mood stabilisers. Clozapine was far more toxic than the other antipsychotics. The findings are relevant to prescribing policy, especially for patients at particular risk of suicidal behaviour.

Trends in the Misuse of Tranquilizers, Sedatives, and Sleeping Pills by Adolescents in Spain, 2004-2014.

PURPOSE: Misuse of prescription medication has increased during the last 20 years among adolescents and young adults. We aimed to report the prevalence and factors associated with misuse of tranquilizers, sedatives, and sleeping pills (TSSp) in high-school students in Spain. We also analyzed misuse of these drugs during the decade 2004-2014. METHODS: Nationwide, epidemiological, cross-sectional study on the misuse of TSSp by the Spanish school population. We used individualized secondary data retrieved from the 2004 and 2014 Spanish State Survey on Drug Use in Secondary Education. A total of 179,114 surveys respondents aged 14-18 years. Estimates and trends of previous 30 days misuse of TSSp. RESULTS: The prevalence of TSSp misuse among school population aged 14-18-years increased significantly from 2004 (2.40%) to 2014 (2.96%). The values for consumption were always greater in adolescent girls than boys throughout the study (3.51% vs. 2.18%). The variables associated with a greater probability of TSSp misuse were consumption of alcohol, tobacco, and marijuana. Students who reported consumption of an illicit drug other than marijuana during the previous year are 4.91 times more likely to misuse TSSp (adjusted odds ratio = 4.91; 95% confidence interval, 4.15-5.81). CONCLUSIONS: We found that misuse of TSSp by adolescents in Spain has significantly increased from 2004 to 2014. Misuse of TSSp was more likely in adolescent girls than Spanish boys. Alcohol, tobacco, and marijuana consumption are factors associated with the use of TSSp.

Prescription drug use, misuse and related substance use disorder symptoms vary by educational status and attainment in U.S. adolescents and young adults.

BACKGROUND: Prescription drug misuse (PDM) rates are highest in adolescents and young adults. Little research in these high-risk groups has examined PDM differences by educational status or attainment. This investigation attempted to further our understanding of adolescent and young adult prescription drug use and misuse through examining PDM type (i.e., nonmedical misuse, medical misuse and mixed misuse) and substance use disorder (SUD) symptoms from PDM by educational status/attainment. METHODS: Data were from the 2015 National Survey on Drug Use and Health, with 13,585 adolescent and 14,553 young adult respondents. Participants were categorized by educational status separately in adolescents and young adults. Outcomes were rates of past-year prescription drug use, PDM, PDM type, and SUD symptoms, with analyses performed separately by age group and for opioids, stimulants and sedatives/tranquilizers. Analyses used logistic regression and controlled for age, race/ethnicity and sex. RESULTS: In adolescents and across medication classes, the highest rates of any use, PDM, medical misuse, nonmedical misuse and presence of two or more SUD symptoms were seen in those with poor school adjustment or not in school. In young adults, opioid-PDM and related outcomes were more prevalent in those not in school, especially high school dropouts. For stimulants, rates were highest in full-time college students and college graduates. CONCLUSIONS: These results further suggest the importance of assessing educational status in adolescent and educational attainment in young adult PDM investigations. Adolescents poorly engaged in school or not in school appear especially in need of interventions to limit PDM and associated SUD symptoms.

Not just heroin: Extensive polysubstance use among US high school seniors who currently use heroin.

BACKGROUND: Heroin-related deaths are on the rise in the US and a large portion of heroin overdoses involve co-use of other drugs such as benzodiazepines. A better understanding of heroin polysubstance use patterns could help discern better prevention measures. METHODS: Data were examined from past-month ("current") heroin users from a nationally representative sample of high school seniors in the Monitoring the Future study (2010-2016, n = 327). We examined how past-month use and frequency of use of various drugs relate to frequency of current heroin use using chi-square and multivariable ordinal logistic regression. RESULTS: Prevalence of any past-month use of various other drugs (and past-month use 10+ times) tends to increase as the frequency of heroin use increases; however, other drug use tends to decline among those reporting the use of heroin 40+ times in the past month. In multivariable models controlling for demographic characteristics, most levels of alcohol use were associated with decreased odds of higher-frequency heroin use (ps<.05). Nonmedical opioid (aOR = 5.84, p = .037) and tranquilizer (aOR = 14.63, p = .045) use 40+ times in the past month were associated with increased odds of higher-frequency heroin use. CONCLUSIONS: High school seniors who use heroin also use multiple other drugs. Increases in the frequency of heroin use are associated with shifts in the nature and frequency of polysubstance use, with a higher frequency of heroin use associated with the highest percentage and frequency of use of depressants (nonmedical opioid and benzodiazepine use), compounding the risk of overdose. Prevention measures should consider polysubstance use patterns among heroin-using adolescents.
