Abstract
OBJECTIVES To compare the use of benzodiazepines, z-hypnotics, gabapentinoids, opioids and centrally acting stimulants (CAS) among patients who had received opioid agonist therapy (OAT) in Norway and Sweden during the period 2015 - 2017. DESIGN A register-based prospective cohort study using information about dispensed drugs from the Norwegian Prescription Database and Swedish Prescribed Drug Register. SETTING Patients who were dispensed OAT opioids from pharmacies. PARTICIPANTS A total of 7176 Norwegian and 3591 Swedish patients on OAT were included. OUTCOME MEASURES The number and frequency of potentially addictive drugs dispensed were calculated for the two countries. The mean daily doses of dispensed benzodiazepines and z-hypnotics were summarised by calculating benzodiazepines in diazepam equivalents and z-hypnotics in zopiclone equivalents. RESULTS In 2017, 46% of patients in Norway, and 15% in Sweden, were dispensed a benzodiazepine. Moreover, 14% in Norway and 26% in Sweden received z-hypnotics. Gabapentinoids were dispensed to 10% of patients in Norway and 19% of patients in Sweden. In Norway, 6% and 12% of the patients received strong and weak non-OAT opioids, respectively, whereas in Sweden 10% were dispensed strong non-OAT opioids and 5% weak non-OAT opioids . CAS were dispensed to 4% in Norway and 18% in Sweden. The mean daily doses of benzodiazepines were 16 and 17 mg diazepam equivalents in Norway and Sweden, respectively. For z-hypnotics, the mean daily dose was 8 mg zopiclone equivalents in both countries. 'Benzodiazepines and z-hypnotics' was the most dispensed drug combination in 2017. Similar results were found in 2015 and 2016. CONCLUSIONS Nearly half of those patients who were dispensed an OAT opioid in Norway and Sweden were dispensed potentially addictive drugs. The differences identified between Norway and Sweden might be related to differences in eligibility guidelines and restrictions with respect to OAT.

Abstract
BACKGROUND Dispensations of opioid analgesics to patients on opioid agonist therapy (OAT) may increase the risk of overdoses. The current study's objectives are to investigate the dispensation rates and mean daily doses of dispensed opioid analgesics among patients who received OAT opioids in Norway during 2013-2017 and evaluate whether discontinuing OAT opioids affects the dispensed dose of opioid analgesics. METHODS Information on opioids was collected from the Norwegian Prescription Database. Dispensation rates were calculated by dividing the number of patients who were dispensed at least one opioid analgesic by the number of patients who were dispensed an OAT opioid. We calculated the mean daily dose of opioid analgesics in oral morphine equivalents. The OAT opioid dose was defined as a ratio between the dispensed doses divided by the mean recommended dose. We used logistic regression to estimate the association between the dispensation of an opioid analgesic, a dose of OAT opioids, having chronic pain, and being on palliative care. RESULTS A total of 10,371 patients were dispensed at least one OAT opioid during the study period. In 2017, 18% were dispensed an opioid analgesic with a mean daily dose of 29 mg of oral morphine equivalents. Being dispensed an opioid analgesic was associated with having chronic pain (adjusted odds ratio (aOR): 3.6, 95% confidence interval: 3.2-4.2), being on palliative care (aOR: 6.1, 4.7-7.9), and receiving an OAT opioid dose below half of the recommended OAT dose (aOR: 1.7, 1.4-2.0). Similar results were seen in 2013-2016. The discontinuation of OAT opioids could increase the dose of dispensed opioid analgesics. CONCLUSION Reducing the dispensation of opioid analgesics can be achieved by increasing the OAT opioid dose for patients on a low OAT dose, and by extending the period needed to taper off the OAT opioid dose at discontinuation.

Uptake and predictors of direct-acting antiviral treatment for hepatitis C among people receiving opioid agonist therapy in Sweden and Norway: a drug utilization study from 2014 to 2017. SUBSTANCE ABUSE TREATMENT PREVENTION AND POLICY 2020; 15:44.

Abstract
Background Treatment with direct-acting antiviral agents (DAAs) offers an opportunity to eliminate hepatitis C virus (HCV) endemic among people who inject drugs (PWID) and people enrolled in opioid agonist therapy (OAT) programs. The objective of this study was to estimate and to compare HCV treatment uptake after the introduction of DAAs among patients receiving OAT in Sweden and Norway. We also aimed to evaluate predictors of DAAs treatment among OAT patients in both countries. Methods This observational study was conducted with data from The Swedish Prescribed Drug Register and The Norwegian Prescription Database. We studied dispensed medications to calculate HCV treatment among OAT patients from 2014 to 2017 in Sweden and Norway. HCV prevalence was estimated from primary and secondary sources. Dispensations of medicines from different therapeutic areas, which served as proxy for co-morbidities in 2017, were conditionally adjusted for age, gender, and OAT medications. Logistic regression was used to evaluate these parameters. Results In total 3529 individuals were identified with dispensed OAT in the Swedish cohort and 7739 individuals in the Norwegian cohort. HCV treatment was utilized by 407 persons in Sweden and 920 in Norway during the study period. Annual HCV and DAA treatment uptake increased in both countries. The estimated cumulative HCV treatment uptake at the end of 2017 was 31% in Norway and 28% in Sweden. DAA treatment was associated with increased age (aOR 1.8; 95% CI 1.0–3.2) and the dispensation of drugs used for diabetes (aOR 3.2; 95% CI 1.8–5.7) in Sweden. In Norway, lipid modifying agents and antibacterials were associated with decreased odds (aOR 0.4; 95%CI 0.2–0.9, aOR 0.8; 95%CI 0.6–1.0). Conclusions An increase in DAA treatment and HCV treatment uptake was observed among Swedish and Norwegian OAT patients whilst introducing new direct-acting antiviral treatment regimens. However, more than two thirds of the OAT population in Norway and Sweden were untreated at the beginning of 2018. A further scale-up is crucial in order to control and eliminate the HCV endemic among OAT patients.

Abstract
IMPORTANCE Understanding the safety profile of medications used in pregnancy is crucial for clinical decision-making. Few studies exist on the associations of exposure to benzodiazepines and benzodiazepine-like hypnotic drugs (z-hypnotics) in pregnancy with pregnancy outcomes. OBJECTIVE To determine whether exposure to benzodiazepines or z-hypnotics in pregnancy is associated with greater risk of negative immediate pregnancy outcomes compared with nonexposure. DESIGN, SETTING, AND PARTICIPANTS This questionnaire-based cohort study used data from the Norwegian Mother, Father and Child cohort study (MoBa), which also includes data from the Medical Birth Registry of Norway. Pregnant women were recruited from all over Norway from 1999 and 2008. The first child was born in October 1999 and the last in July 2009. This analysis included women who completed 3 questionnaires, twice during pregnancy and once 6 months after delivery. Data analyses were conducted from September to November 2019. EXPOSURES Self-reported exposure to benzodiazepines or z-hypnotics during pregnancy, characterized in terms of any exposure, timing (ie, early, middle, or late), and duration of exposure. MAIN OUTCOMES AND MEASURES The main outcomes were gestational age at delivery, risk of preterm delivery, birth weight, birth weight relative to gestational age and sex, risk of being small for gestational age, head circumference, Apgar score less than 7 at 5 minutes, and risk of neonatal respiratory distress. Continuous outcomes are reported using effect estimates as mean differences, and binary outcomes are reported using risk ratios. RESULTS The MoBa study included 114 234 mother-child dyads. This analysis of MoBa data includes 82 038 singleton pregnancies among 69 434 unique women. Mean (SD) maternal age was 30.2 (4.5) years, and 37 641 pregnancies (45.9%) were in primiparous women. Exposure to benzodiazepines or z-hypnotics was reported in 679 pregnancies (0.8%). After adjusting for all measured baseline and postbaseline confounders, benzodiazepine or z-hypnotic use during pregnancy was associated with lower birth weight (mean difference, -79.3 [95% CI, -126.7 to -31.9] g), lower gestational age at birth (mean difference, -2.1 [95% CI, -3.3 to -0.9] days), and higher risk of preterm birth (risk ratio, 1.41 [95% CI, 1.03 to 1.94]). We found no significant association of exposure to benzodiazepines or z-hypnotics with the child's birth weight relative to gestational age and sex (z score), or any of the other immediate birth outcomes. CONCLUSIONS AND RELEVANCE These findings suggest that the magnitude of the association of exposure to benzodiazepines or z-hypnotics with gestational age is not necessarily clinically significant. The absence of an association of exposure to benzodiazepines or z-hypnotics with z score for birth weight relative to gestational age and sex suggests that association of exposure to benzodiazepines or z-hypnotics with birth weight could be explained by earlier delivery rather than impaired intrauterine growth.

Abstract
Background: WHO guidelines emphasise the need for descriptions of clinical practice and observational studies on risk and benefits of pharmacotherapies in pregnancy. The aims of the present study were to: (1) Describe opioid maintenance treatment (OMT) in the Scandinavian countries in general, and specifically for pregnant women, (2) Describe a project which utilises a new approach using registry-linkage data to examine associations between prenatal exposure to OMT and child outcomes: a Scandinavian cohort study of pregnant women in OMT during pregnancy (ScopeOMT). Data: Guidelines describing the treatment of persons with opioid use disorders in general, and specifically for pregnant women. Scandinavian registry-linkage data from ScopeOMT. Results: Registry data show that approximately 800 pregnant women received OMT during pregnancy in the period of the ScopeOMT study. Similarities across the Scandinavian countries include access to free healthcare and treatment; multidisciplinary teams trained to support pregnant women in OMT; buprenorphine as the recommended drug when initiating therapy; and a holistic focus on the patients’ lives. An important difference is that Norwegian women who use illegal substances that may harm the foetus may be admitted – voluntarily, or against their will – for parts of, or the remainder of the pregnancy to inpatient treatment at specialised clinics. Conclusion: Many similarities in the treatment provided to opioid-dependent persons in the Scandinavian countries place this area in an excellent position to combine the efforts and carry out observational studies concerning the safety of OMT during pregnancy.

Abstract
PURPOSE An increasing consumption of opioids has been reported. The primary aim of the present study was follow-up of neurocognitive development in children exposed to analgesic opioids during pregnancy, using three different validated instruments to assess language and communication development at 5 years. METHODS The Norwegian Mother and Child Cohort Study (MoBa) prospectively included pregnant women 1999 to 2008. Participants reported medication use at pregnancy week 17/18 and 30, and 6 months after birth. Children's language competence and communication skills at 5 years were reported by mothers on three different validated scales; The Ages and Stages Questionnaire (ASQ), The Speech and Language Assessment Scale (SLAS) and The Twenty Statements about Language-Related Difficulties list (Language20Q). RESULTS A total of 27 428 women with 33 407 singleton pregnancies were included. Use of analgesic opioids was reported in 584 pregnancies (1.7%). No associations between opioid use and lower language competence or communication skills were found. For ASQ, the OR of being in the lowest category vs the group with maximum mean score was 0.82 (95%CI 0.57, 1.17), for SLAS the OR of scoring worse than typical for age vs better than typical for age was 0.84 (0.61, 1.17) in children exposed to opioids in utero. For Language20Q using the best performance category as reference, the OR of scoring in the lower performance category was 0.57 (0.35, 0.91) with exposure to opioids. CONCLUSION Use of analgesic opioids in pregnant women does not seem to negatively affect language development or communication skills in children at 5 years.

Abstract
Background Dispensations of benzodiazepines, z-hypnotics, and gabapentinoids to patients on opioid agonist therapy (OAT) are common and have pros and cons. The objectives of the current study are to define the dispensation rates of these potentially addictive drugs, and whether the number and the mean daily doses of dispensed OAT opioids and discontinuing OAT, are associated with being dispensed benzodiazepines, z-hypnotics and gabapentinoids among patients on OAT in Norway in the period 2013 to 2017. Methods Information about all dispensed opioids, benzodiazepines, z-hypnotics and gabapentinoids were recorded from the Norwegian Prescription Database (NorPD). A total of 10,371 OAT patients were included in the study period. The dispensation rates were defined as the number of patients who were dispensed at least one of the potentially addictive drugs divided among the number of patients who have dispensed an OAT opioid per calendar year. Mean daily doses were calculated, and for benzodiazepines and z-hypnotics, stated in diazepam equivalents. The association between dispensed potentially addictive drugs, and the number and the type of dispensed OAT opioids were calculated by using logistic regression models. Results Half of the OAT patients received at least one dispensation of a benzodiazepine or z-hypnotic, and 11% were dispensed at least a gabapentinoid in 2017. For dispensed benzodiazepines or z-hypnotics, the mean daily dose was reduced from 21 mg (95% confidence interval (CI): 20–23) diazepam equivalents in 2013 to 17 mg (95% CI: 16–17) in 2017. The mean daily dose of pregabalin increased from 365 mg (95% CI: 309–421) in 2013 to 386 mg (95% CI: 349–423) in 2017. Being dispensed a gabapentinoid (adjusted odds ratio (aOR) = 2.5, 95% CI: 2.1–3.0) or a non-OAT opioid (aOR = 3.0, 95% CI: 2.6–3.5) was associated with being dispensed a benzodiazepine or z-hypnotic. Discontinuing OAT did not affect the number of dispensations and the doses of potentially addictive drugs. Conclusion The dispensation rates of potentially addictive drugs are high in the OAT population. Treatment indications, as well as requirements for prescription authority, need to be debated and made explicit. Randomized controlled trials evaluating the benefits and risks of such co-prescription are required.

Abstract
BACKGROUND Maternal substance use can pose a risk to the fetal health. We studied the background characteristics of women with substance use disorders (SUDs) and selected neonatal outcomes in their children. MATERIAL AND METHODS A database-linkage study was performed. The sample consisted of pregnant women with a SUD during pregnancy (ICD-10 diagnosis F10-F19 except F17, n = 1710), women not diagnosed with a SUD (n = 1,511,310) in Czechia in 2000-2014, and their children. The monitored neonatal outcomes were gestational age, birth weight, preterm birth, and small-for-gestational age (SGA). Binary logistic regression adjusted for age, marital status, education, concurrent substance use, and prenatal care was performed. RESULTS Women with illicit SUDs were younger, more often unmarried, with a lower level of education, a higher abortion rate, a higher smoking rate, and lower compliance to prenatal care than women with a SUD related to alcohol, or sedatives and hypnotics (SH). Women with a SUD had worse socioeconomic situations, poorer pregnancy care, and worse neonatal outcomes than women without a SUD. After adjustment, we found no difference in SGA between the illicit SUD groups and the alcohol and the SH groups. The newborns from all SUD groups had a higher risk of SGA when compared to women without a SUD. However after adjustment, the difference remained significant just in the alcohol group (OR = 1.9, 95 % CI = 1.4-2.6). CONCLUSION Mother's SUD during pregnancy increased risk of fetal growth restriction as measured by SGA. The role of maternal socioeconomic and lifestyle factors for the risk of SGA was substantial.

Abstract
BACKGROUND It is estimated that up to a third of patients on opioid agonist therapy (OAT) have attention deficit hyperactivity disorder (ADHD). Treatment by ADHD medication, including a centrally acting stimulant (CAS) or atomoxetine is one of the essential approaches. This study evaluates the use of dispensed ADHD medications in the Norwegian OAT population in the period from 2015 to 2017. Types and doses of ADHD medications, co-dispensations of other potentially addictive drugs like benzodiazepines, z-hypnotics, gabapentinoids, and non-OAT opioids, as well as direct-acting antivirals (DAA) against hepatitis C infection, are investigated. METHODS Information about all dispensed ADHD medication, OAT opioids, and the defined potentially addictive drugs were recorded from the Norwegian Prescription Database. Dispensation rates, the types, and the doses of dispensed ADHD medications were estimated by summarizing the number of dispensations, and the dispensed doses. Logistic regression analyses were employed to assess the associations between ADHD medication, and OAT opioid use, and dispensations of other potentially addictive drugs and DAAs against hepatitis C infection. RESULTS A total of 9235 OAT patients were included. The proportion of patients who were dispensed ADHD medication increased from 3.5 to 4.6% throughout the study period. The three most dispensed CAS were short- and intermediate-acting methylphenidate (55%), lisdexamphetamine (24%), and dexamphetamine (17%) in 2017. Buprenorphine, rather than methadone, as OAT opioid (adjusted odds ratio: 1.6, CI: 1.2-2.1) was associated with being dispensed ADHD medication. Among patients who received CAS and OAT opioids each calendar year, the dispensed doses of methylphenidate increased from 63 mg/day in 2015 to 76 mg/day in 2017 (p = 0.01). Sixty percent of patients receiving ADHD medications were also dispensed other addictive drugs concomitantly in 2017. Similar results were found in 2015 and 2016. CONCLUSION Co-prescription of ADHD medications was low among patients on OAT in Norway, considering a high prevalence of ADHD in this patient group. On the other hand, concurrent dispensations of multiple addictive drugs were common in this population. Understanding the underlying reasons for such prescribing is essential, and research on how to optimize ADHD medication of patients with ADHD receiving OAT is needed.

Abstract
Purpose: Autism spectrum disorder (ASD) has a high rate of comorbidity. While many children with ASD are exposed to psychotropic medicines, their efficacy and safety in these patients are unclear. There is a need for more detailed knowledge on which medicines are most commonly used and for which disorders. We aimed to investigate (a) prevalence and incidence rate of ASD among Norwegian children, and further, among newly diagnosed ASD children in 2014, study the (b) co-occurrence of neuropsychiatric disorders, (c) use of psychotropic drugs, and (d) the relationship between co-occurring diagnoses and use of psychotropic drugs. Method: Nationwide registry-based study of children 2-17 years old in Norway. Results: The ASD prevalence was 0.76% and the incidence rate was 0.12% in 2014. Of the children who received an initial ASD diagnosis in 2014 (n = 1,234), 64.8% had one or more co-occurring neuropsychiatric diagnosis. Psychotropic medication use was moderate (~20% used stimulants or hypnotics) in general, and low in children without comorbidity (nearly only hypnotics). There was a good accordance between co-occurring diagnoses and indication for the prescribed medications. Conclusions: Children with newly diagnosed ASD mainly received psychotropic drugs to treat co-occurring neuropsychiatric conditions.

Abstract
UNLABELLED Proton pump inhibitors (PPIs) have been linked to increased risk of fracture; the data have, however, been diverging. We did not find any increased risk of fractures among users of PPIs in a Norwegian population of 15,017 women and 13,241 men aged 50-85 years with detailed information about lifestyle and comorbidity. INTRODUCTION Proton pump inhibitors (PPIs) are widely prescribed and have been linked to increased risk of fracture. METHODS We used data from the Nord-Trøndelag Health Study (HUNT3), The Fracture registry in Nord-Trøndelag, and the Norwegian Prescription Database, including 15,017 women and 13,241 men aged 50-85 years. The study population was followed from the date of participating in HUNT3 (2006-2008) until the date of first fracture (forearm or hip), death, or end of study (31 December 2012). The Cox proportional hazards model with time-dependent exposure to PPIs was applied, and each individual was considered as unexposed until the first prescriptions was filled. To be included, the prescription of PPIs should minimum be equivalent to 90 defined daily doses (DDD) in the period. Individuals were defined as exposed until 6 months after end of drug supply. RESULTS The proportion of women and men using PPIs was 17.9% and 15.5%, respectively. During a median of 5.2 years follow-up, 266 women and 134 men had a first hip fracture and 662 women and 127 men, a first forearm fracture. The combined rate/1000 patient-years for forearm and hip fractures in women was 49.2 for users of PPIs compared with 64.1 among non-users; for men 18.6 and 19.8, respectively. The hazard ratios with 95% confidence interval for the first forearm or hip fracture among users of PPIs in the age-adjusted analysis were 0.82 (0.67-1.01) for women and 1.05 (0.72-1.52) for men. Adjusting for age, use of anti-osteoporotic drugs, and FRAX, the HR declined to 0.80 (0.65-0.98) in women and 1.00 (0.69-1.45) in men. CONCLUSIONS Use of PPIs was not associated with an increased risk of fractures.

Abstract
BACKGROUND Tourette syndrome first appears in childhood and is characterised by chronic motor and vocal tics. In other countries, the mean prevalence is estimated at 0.77 % in children aged 6-15 years. Diagnostic practice and treatment have not been investigated in Norway. MATERIAL AND METHOD We used data retrieved from the Norwegian Patient Registry and the National Registry to calculate the percentage of children born during the period 2002-10 diagnosed with Tourette syndrome. The calculations were made for the country as a whole as well as by county. Drug therapy was investigated using data from the Norwegian Prescription Database. RESULTS By the age of 12, altogether 0.43 % had received a diagnosis of Tourette syndrome, broken down into 0.71 % for boys and 0.15 % for girls. The overall percentage varied from 0.15 % to 1.23 % between the counties. For Norway as a whole, the percentage of diagnoses remained stable between 2008 and 2016. Psychiatric and neurological conditions were often present - the most common being hyperkinetic disorder (50 %) and autism spectrum disorder (11 %). Antipsychotic drugs, probably for the treatment of tics, were prescribed for 16 % in the year following the diagnosis. INTERPRETATION The percentage of children with a diagnosis of Tourette syndrome is lower than the mean prevalence in population studies internationally. The diagnostic practice varies considerably from county to county.

Abstract
Background: Paternal lifestyle during sperm development can have an impact on foetal
development. This study surveys demographic characteristics and lifestyle
factors among expectant fathers who reported use of cannabis and cocaine in
the six-month period before conception. We also study the associations
between mothers’ and fathers’ use of cannabis and cocaine. Methods: This is a cross-sectional study from the Norwegian Mother and Child Cohort
Study (MoBa) using self-reported data on demographic variables and cannabis
and cocaine use six months before conception. Associations were assessed
using logistic regression and chi-square tests. Results: A strong association was found between use of cannabis and cocaine and
lifestyle habits such as alcohol and cigarette use. Alcohol consumption four
or more times a week gave an adjusted odds ratio (aOR) of
9.7 (95% CI 7.2–13.0) for cannabis and an aOR 21.6 (95% CI
11.5–40.3) for cocaine. There was also a strong association between maternal
and paternal use of cannabis and cocaine. Conclusion: Use of cannabis and cocaine close to pregnancy seems to be closely linked to
other risk factors, and further studies on how paternal drug use affects the
foetus are warranted. The strong association between maternal and paternal
use of cannabis and cocaine may be used to inform healthcare workers to make
good risk assessments.

Abstract
Background A large proportion of people who inject drugs (PWID) living with hepatitis C virus (HCV) infection have not been treated. It is unknown whether inclusion of HCV diagnostics and treatment into integrated substance use disorder treatment and care clinics will improve uptake and outcome of HCV treatment in PWID. The aim is to assess the efficacy of integrating HCV treatment to PWID and this paper will present the protocol for an ongoing trial. Methods INTRO-HCV is a multicentre, randomised controlled clinical trial that will compare the efficacy of integrated treatment of HCV in PWID with the current standard treatment. Integrated treatment includes testing for HCV, assessing liver fibrosis with transient elastography, counselling, treatment delivery, follow-up and evaluation provided by integrated substance use disorder treatment and care clinics. Most of these clinics for PWID provide opioid agonist therapy while some clinics provide low-threshold care without opioid agonist therapy. Standard care involves referral to further diagnostics, treatment and treatment follow-up given in a hospital outpatient clinic with equivalent medications. The differences between the delivery platforms in the two trial arms involve use of a drop-in approach rather than specific appointment times, no need for additional travelling, less blood samples taken during treatment, and treatment given from already known clinicians. The trial will recruit approximately 200 HCV infected individuals in Bergen and Stavanger, Norway. The primary outcomes are time to treatment initiation and sustained virologic response, defined as undetectable HCV RNA 12 weeks after end of treatment. Secondary outcomes are cost-effectiveness, treatment adherence, changes in quality of life, fatigue and psychological well-being, changes in drug use, infection related risk behaviour, and risk of reinfection. The target group is PWID with HCV diagnosed receiving treatment and care within clinics for PWID. Discussion This study will inform on the effects of an integrated treatment program for HCV in clinics for PWID compared to standard care aiming to increase access to treatment and improving treatment adherence. If the integrated treatment model is found to be safe and efficacious, it can be considered for further scale-up. Trial registration ClinicalTrials.gov.no. NCT03155906.

Abstract
BACKGROUND It is generally agreed that prescribing of antipsychotic drugs to older patients should be reduced, but figures for the prescribing of these drugs to older patients living at home in Norway are not available. The study aimed to investigate developments in prescribing of antipsychotic drugs among older patients living at home from 2006 to 2018, and whether there were differences in prescribing rates between the age groups 65-74 years, 75-84 years and 85 years or older. MATERIAL AND METHOD Data were retrieved from the Norwegian Prescription Database. All persons aged 65 years or older who were dispensed at least one antipsychotic drug in 2006, 2010, 2014 and 2018 were included, and gender-specific prevalence for the ten most widely used antipsychotic drugs was calculated. RESULTS The proportion of patients aged 65 or older who were prescribed antipsychotic drugs in the period decreased for both sexes. For the age group 65-74 years, an increase was found from 2014 to 2018. There was a clear decrease in the prescribing rate for prochlorperazine and levomepromazine, whereas prescriptions for quetiapine increased. INTERPRETATION Attention should be paid to the increase in prescribing of antipsychotic drugs for the youngest age group of older patients (65-74 years) in the last four years, along with the increase in prescribing of quetiapine for older patients.

Abstract
There is lack of knowledge about the safety of treatment with methadone and buprenorphine as part of opioid maintenance treatment (OMT) during pregnancy. The purpose of this study was to examine neonatal outcomes concerning the use of OMT during pregnancy. We used nationwide registry linkages from the Czech Republic (2000-2014) and Norway (2004-2013). We compared prenatally OMT-exposed newborns with (a) newborns of women hospitalized with opioid use disorder during pregnancy in the Czech sample and (b) newborns with neonatal abstinence syndrome (NAS) in Norway. We performed multivariate linear and binary logistic regression exploring the associations between OMT and neonatal outcomes (growth parameters, gestational age, fetal death, small for gestational age, Apgar score, and NAS). Regression coefficients (b) and odds ratios (ORs) were estimated. The cohorts consisted of 333 Czech, and 235 Norwegian OMT-exposed newborns, and 106 and 294 newborns in the comparison groups, respectively. In both countries, the neonatal growth parameters were similar in the OMT and the comparison groups. In Norway, OMT exposure prolonged gestational age (adjusted b = 0.96 weeks, 95% confidence interval [CI] =0.39-1.53) while the odds of preterm birth and Apgar score at 5 minutes were lower than in the comparison group (adjusted OR = 0.35, 0.16-0.75 and aOR = 0.21, 0.06-0.78, respectively). Newborns of women in OMT had similar growth parameters as newborns of women with opioid use disorders who were not in OMT during pregnancy. Overall, our findings do not suggest that OMT results in worse neonatal outcomes.

Abstract
Background and aims Dextropropoxyphene (DXP) is a synthetic opioid that was prescribed worldwide for mild to moderate pain. It was withdrawn from the European market in 2009. In this study we aim to investigate the effect of the market withdrawal of dextropropoxyphene in Norway on overall use of opioids and other analgesics at an individual level. Methods Data were collected from the nationwide Norwegian Prescription Database (NorPD). It covers all prescription of drugs from 01 January 2004 from Norwegian pharmacies dispensed to individuals outside institutions. The study period was divided in two 2-year periods from 01 September 2008 to 31 August 2010, and from the market withdrawal of DXP on 01 September 2010 to 31 August 2012. We included every individual that filled at least one prescription of dextropropoxyphene in the first 2-year period in our study population. In this study dextropropoxyphene, codeine and tramadol are defined as "weak opioids", and all other opioids are termed "strong opioids". Results Nine thousand one hundred and seventy-one individuals were included in our study population. Four thousand two hundred and ninety filled a prescription of DXP only once and were classified as "single users", 2,990 were users with prescriptions of up to 200 defined daily doses (DDD) over the first 2-year period, or "sporadic users", and 1,886 were classified high users with over 200 DDDs over a 2-year period. After the market withdrawal 8,392 continued to be prescribed analgesics or benzodiazepines. In the single user group, the proportion of users of weak opioids decreased from 69.5% to 57.6%, whereas the proportion of users of strong opioids was unchanged. Among the sporadic user group, the proportion of users of weak opioids went from 69.7% to 71.0%, the proportion using tramadol from 39.1% to 43.9%, and the users of strong opioids from 25.8% to 31.3%. In the high user group, there was an increase in the number of users of strong opioids from 37.8% to 51.4%. The amount of strong opioids prescribed in the high user group increased from a mean of 262.5 DDD to a mean of 398.3 DDD in the following 2 years. The amount of tramadol increased in all groups and was 3 times as high in the high user group after market withdrawal of DXP. Conclusions Our study showed that the withdrawal of DXP lead to an increase in prescription of other analgesics. The proportion of users increased in all three groups and so did the prescribed amount of other analgesics. Both the proportion of users of other opioids and the amount prescribed increased considerably. However, 1 in 10 earlier users of DXP stopped using prescribed analgesics altogether in the following 2 years. The increase in use among earlier high users of DXP was most striking. Implications This study documents markedly increased prescriptions of other opioids after withdrawal of dextropropoxyphene due to its high risk of serious complications. However, consequences of the increased use of opioids among earlier high users of DXP such as changes in risk of poisonings, accidental deaths and suicides remain to be investigated.

Abstract
BACKGROUND AND AIMS Our understanding of the long-term safety of prenatal exposure to opioid maintenance treatment (OMT) is insufficient. We compared childhood morbidity (0-3 years) between OMT-exposed and relevant comparison groups. DESIGN Nation-wide, registry-based cohort study. Registries on reproductive health, addiction treatment, hospitalization and death were linked using identification numbers. SETTING The Czech Republic (2000-14). PARTICIPANTS Children with different prenatal exposure: (i) mother in OMT during pregnancy (OMT; n = 218), (ii) mother discontinued OMT before pregnancy (OMT-D; n = 55), (iii) mother with opioid use disorder, but not in OMT during pregnancy (OUD; n = 85) and (iv) mother in the general population (GP) (n = 1 238 452) MEASUREMENTS: Episodes of hospitalization were observed as outcomes. Information on in-patient contacts, length of stay and diagnoses (International Classification of Diseases version 10) were assessed. Binary logistic regressions were conducted to estimate the associations between OMT exposure and the outcomes, crude and adjusted for the socio-economic status and smoking. FINDINGS No significant differences were found in the overall proportion of hospitalization among OMT-exposed children, children of OMT-D and children of women with OUD [54.1%, 95% confidence interval (CI) = 47.3-60.1%; 47.3%, 95% CI = 33.9-61.1%; 51.8%, 95% CI = 40.7%-62.6%], while the proportion was significantly lower (35.8%, 95% CI = 35.7-35.8%) in the GP. There were no significant differences in risk of specific diagnoses between OMT-exposed children, children of OMT-D and children of women with OUD. In the adjusted analyses, differences between OMT-exposed and children in the GP were still present for infections and parasitic diseases (OR = 2.0, 95% CI = 1.4-2.7), diseases of the digestive system (OR = 1.7, 95% CI = 1.2-2.6) and diseases of the skin and subcutaneous tissue (OR = 1.9, 95% CI = 1.2-3.2). CONCLUSION This study did not find clear evidence for an increase in risk of morbidity during the first 3 years of life in children with prenatal opioid maintenance treatment exposure compared with children of women who discontinued such treatment before pregnancy or suffered from opioid use disorder without this treatment. Compared the general population, there appears to be an increased risk of hospitalizations for infectious, gastrointestinal and skin diseases.

Abstract
IMPORTANCE The reproductive safety of benzodiazepine/z-hypnotic exposure on child longer-term developmental risks remains unresolved. OBJECTIVE To quantify the association of motor, communication, and attention-deficit/hyperactivity disorder (ADHD) symptoms in preschoolers with gestational benzodiazepine/z-hypnotic exposure by timing and duration and coexposure to opioids or antidepressants. DESIGN, SETTING, AND PARTICIPANTS Nationwide, population-based Norwegian Mother and Child Cohort Study, recruiting pregnant women from 1999 to 2008, with child follow-up from ages 6, 18, and 36 months to ages 5, 7, and 8 years. Follow-up of teenagers is ongoing. The study included women with depressive/anxiety (n = 4195), sleeping (n = 5260), or pain-related (n = 26 631) disorders before and/or during pregnancy. EXPOSURES For the timing analyses, children exposed to benzodiazepines/z-hypnotics in midpregnancy (weeks 17-28) or late pregnancy (week 29 or later) vs those born to nonmedicated women. For the duration and coexposure analyses, benzodiazepine/z-hypnotic treatment for multiple 4-week intervals vs 1 and co-use of benzodiazepine/z-hypnotic with opioids or antidepressants vs sole benzodiazepine/z-hypnotic use. MAIN OUTCOMES AND MEASURES Parent-reported motor and communication skills (Ages and Stages Questionnaires) and ADHD symptoms (Conners' Parent Rating Scale-Revised) at child median age of 5.1 years (interquartile range, 5.0-5.3 years) as standardized mean scores. General linear propensity score-adjusted and marginal structural models were fitted. Analyses were stratified by maternal disorder. RESULTS Of 41 146 eligible pregnancy-child dyads, 36 086 children (18 330 boys and 17 756 girls) were included, of whom 283 (0.8%) were prenatally exposed to benzodiazepines/z-hypnotics (134 in the depressive/anxiety, 60 in the sleeping, and 89 in the pain-related disorders). There was no increased risk for greater ADHD symptoms or fine motor deficits after intrauterine benzodiazepine/z-hypnotic exposure at different time points. Children born to women with depressive/anxiety disorders who took benzodiazepines/z-hypnotics in late pregnancy had greater gross motor (weighted β, 0.67; 95% CI, 0.21-1.13) and communication (weighted β, 0.35; 95% CI, 0.04-0.65) deficits than unexposed children. There was no evidence for substantial duration or coexposure associations. CONCLUSIONS AND RELEVANCE These findings suggest no substantial detrimental risk on child fine motor and ADHD symptoms after prenatal benzodiazepine/z-hypnotic exposure alone or in combination with opioids or antidepressants. Residual confounding by indication and/or a higher drug dose regimen among women with anxiety/depression may explain the moderate association of gross motor and communication deficits with late-pregnancy benzodiazepine/z-hypnotic use.

Abstract
BACKGROUND Quality of life (QoL) is an established outcome measure of substance use disorder treatment. The WHOQOL-BREF is the gold standard tool, but its appropriateness for particularly vulnerable patient populations must be further explored. This article examines the scaling qualities of the WHOQOL-BREF in a Norwegian substance use disorder population, and explores relationships with social and health variables. METHODS 107 participants in a larger national treatment study provided data during structured interviews. Item responses, responsiveness, and domain scaling qualities are reported. General linear models identified correlates of impaired QoL. RESULTS Three out of four domains exhibited acceptable scaling qualities, while the social relationships domain had low internal validity. 59% of the variance in physical health QoL was explained in our model by the negative main or interaction effects of depression, unemployment, social isolation, smoking, residential treatment, and weight dissatisfaction. 52% of the variance in psychological health QoL was explained by depression and being single. Depression also had significant main effects in social relationships QoL (R2 = .27) and environment QoL (R2 = .39), and social isolation and exercise had further interaction effects in environment QoL. CONCLUSIONS After one year in treatment, the impact of low social contact in reducing QoL, rather than specific substance use patterns, was striking. The social relationships domain is the shortest in the WHOQOL-BREF, yet social variables were important in other areas of QoL. Social support could benefit from more attention in treatment, as a lack of social support seems to be a strong risk factor for poor QoL in various domains. The WHOQOL-BREF exhibits otherwise satisfactory measurement characteristics and is an appropriate tool among this population.

Abstract
IMPORTANCE The research focus on children of parents with alcohol use disorder has eclipsed the potentially wider-reaching detrimental effects of subclinical parental drinking, both alone and in combination with other parental risk factors. OBJECTIVE To identify constellations of early parental risk characterized by variations in drinking, mental health, and education in both parents and examine their prospective associations with children's contact with the health care system for anxiety and/or depression (ie, diagnoses or treatment). DESIGN, SETTING, AND PARTICIPANTS This prospective study was based on linked survey and health registries data. The sample included 8773 children from 6696 two-parent families in Norway who participated in the Nord-Trøndelag Health Study (HUNT) survey in 1995 to 1997 or 2006 to 2008, when the children were aged 13 to 19 years. Data were analyzed from January to September 2018. EXPOSURES Five constellations of early parental risks, characterized by variations in drinking frequencies and amounts, mental health, and education for both parents, as identified through latent profile analysis. MAIN OUTCOMES AND MEASURES Children's diagnoses or treatment of anxiety and/or depression from 2008 to 2016 were recorded in 3 health registries. The primary outcome was the total number of registries where participants presented (ranging from 0 to 3). RESULTS Of the 8773 included children, 4404 (50.2%) were boys, and the mean (SD) age at the time of participation in the Nord-Trøndelag Health Study was 16.1 (1.8) years. Prevalence of anxiety and/or depression, as evidenced in at least 1 registry record, was 24.3% (2132 of 8773). Early parental risk profiles risks marked by (1) the lowest parental education (adjusted relative risk, 1.13; 95% CI, 1.01-1.25) and (2) elevated drinking in both parents and elevated mental health symptoms in fathers (adjusted relative risk, 1.52; 95% CI, 1.03-2.22) were associated with a significant increase in risk of anxiety and/or depression in children from those families compared with children from no-risk families. CONCLUSIONS AND RELEVANCE Studies seeking to understand prospective associations of parental drinking with children's mental health need to consider additional risk factors in combination with one another as well as parental behaviors and characteristics below clinically defined levels. When accumulated at a family level, even seemingly innocuous characteristics contributed to meaningful increases in risk of anxiety and/or depression among children, potentially translating into poorer mental health outcomes for many young people.

Abstract
Abstract
Background and aims
While the Nordic countries have considerably stricter controls on opioid prescribing for chronic non-cancer pain than other countries, previous research has warned that prescription of strong opioids is increasing. This study examines consumption of and developments in dispensed prescribed opioids to individuals receiving ambulatory care from 2006 to 2017, using publicly available data from each of three Nordic countries’ national prescription registries.
Methods
Repeated, cross-sectional design. One-year prevalence of all dispensed prescribed opioids in ATC N02A group were reported for Norway, Denmark, and Sweden in the period 2006–2017 by gender. One-year prevalence of the weak opioids tramadol and codeine and the strong opioid oxycodone were then reported separately over this period for each country. The mean defined daily dose (DDD) per user per year, an estimate of the amount of opioids prescribed, was reported for each of the three opioids in 2016.
Results
Patterns of dispensed prescribed opioids differ greatly between 2006 and 2017 and between countries, with tramadol increasing in Norway, codeine declining across the board, and oxycodone increasing in all three countries. Norway exceeded Sweden and Denmark in prevalence of all dispensed prescribed opioids, with 12.1% of the female Norwegian population and 9.2% of the male Norwegian population dispensed at least one prescribed opioid as an outpatient in 2016. Norway’s high overall prevalence rates are tempered by dispensing the lowest mean doses of both weak opioids compared to Sweden. Similarly, Sweden dispenses the lowest mean doses of oxycodone but to the largest proportion of its population (3.0%).
Conclusions
Significant shifts have occurred in the dispensing of prescribed opioids in Norway, Sweden, and Denmark over the past 12 years. The increasing prevalence of oxycodone in all three countries should continue to be monitored. Prescription registries provide a wealth of publicly available data that can be used to monitor and to guide prescribing policies in a more knowledge-based direction.
