ObjectivesDistribution of take-home naloxone is suggested to reduce opioid-related fatalities, but few studies have examined the effects on overdose deaths in the general population of an entire community. This study aimed to assess the effects on overdose deaths of a large-scale take-home naloxone programme starting in June 2018, using an observational design with a historic control period.DesignFrom the national causes of death register, deaths diagnosed as X42 or Y12 (International Classification of Diseases, 10th revision, ICD-10) were registered as overdoses. Numbers of overdoses were calculated per 100 000 inhabitants in the general population, and controlled for data including only individuals with a prior substance use disorder in national patient registers, to focus on effects within the primary target population of the programme. The full intervention period (2019–2021) was compared with a historic control period (2013–2017).SettingSkåne county, Sweden.ParticipantsGeneral population.InterventionsLarge-scale take-home naloxone distribution to individuals at risk of overdose.Primary and secondary outcome measuresDecrease in overdose deaths per 100 000 inhabitants, in total and within the population with substance use disorder diagnosis.ResultsAnnual average number of overdose deaths decreased significantly from 3.9 to 2.8 per 100 000 inhabitants from the control period to the intervention period (a significant decrease in men, from 6.7 to 4.3, but not in women, from 1.2 to 1.3). Significant changes remained when examining only prior substance use disorder patients, and decreases in overdose deaths could not be attributed to a change in treatment needs for opioid use disorders in healthcare and social services.ConclusionsThe present study, involving 3 years of take-home naloxone distribution, demonstrated a decreased overdose mortality in the population, however, only in men. The findings call for further implementation of naloxone programmes, and for further studies of potential effects and barriers in women.Trial registration numberNCT03570099.

Objectives: To present sales figures of antifungal drugs for treatment of genital Candida infections in females, which had been purchased in the Swedish county of Skåne (with approximately 1.2 million inhabitants) during the 1990s. To study the relative proportions of the drugs sold by prescription and as over-the-counter (OTC) products. Methods: Sales figures of antifungal drugs for therapy of vulvovaginal candidiasis (VVC) and such recurrent infections (RVVC), for the years 1990-99, were collected from the 'ACS' database of the National Corporation of Swedish Pharmacies. Results: The study showed an increase in sales of the type of drugs studied from 45 000 packages in 1990 until mid-93/94, when approximately 70 000 packages were sold (mainly azoles for topical use and fluconazole for oral intake). Thereafter there was a decrease until the end of November 1999, when 54 000 packages were purchased. Of the total sales, 93% were OTC products. Sales of clotrimazole and econazole (for vaginal installation) in 1993-1994 were equal to 85-90 packages/1000 women in the age group 15-45 years. Extremely high sales volumes of fluconazole and itraconazole, for one single year each, could be explained by marketingrelated activities directed to the medical community. Conclusions: As many women with RVVC are not cured by iatrogenic initiatives and women consider themselves able to diagnose episodes of genital Candida infection, affected women generally turn to selfmedication with antifungal OTC products. This stresses the role of pharmacy counseling. Short-term marked alterations in sales volumes may be due to marketing factors rather than changes in the epidemiology of genital Candida infections.

Background: The epidemiology of vulvovaginal candidiasis (VVC) and such recurrent infections (RVVC) has been difficult to study as the majority of episodes of these conditions are self-treated by the women affected. In Sweden, all pharmacies are owned by the state and all prescriptions and over-the-counter (OTC) products, such as antifungals, are registered in a database, which offers unique possibilities to study the epidemiology of VVC/RVVC. Objectives: To analyze all prescriptions and OTC products purchased for therapy of VVC/RVVC and to establish reasons for any observed variation in the sales figures. Methods: Sales figures in the Swedish county of Skåne of antifungal drugs for therapy of VVC/RVVC were analyzed by the aid of the 'ACS' database of the National Corporation of Swedish Pharmacies for the years 1990-1999. The size of the female population in the county is approximately half a million. Results: The study showed that 93% of all antifungal drugs for VVC/RVVC were sold as OTC products. An increase in sales of the drugs occurred until mid-1993/94, followed by a decrease until end of the study period in 1999. Demographic factors (e.g. the number of female inhabitants in the county, pharmacies and health-care units), the pregnancy rate and pharmacy-dependent factors (such as the introduction of shelves for selfselection of antifungal products) did not explain the observed variations in sales. Distinct short-term variations in the number of prescriptions of fluconazole and itraconazole could be explained by drugs company sales campaigns and logistics factors in drug distribution. The sales volumes in the 33 municipalities in the county correlated with the density of the population, which was not the case for the total number of prescriptions made in the county during the 1990s. The variation in antifungal drug sales was similar to that of hormonal intrauterine devices, but this was not the case for oral contraceptives. The total Swedish usage of antibiotics showed a similar variation to that of the antifungal drugs analyzed. Conclusion: The study stresses the limited impact on the treatment of VVC/RVVC by the medical community. Behavior-related factors in the female population are the most likely explanation for the marked variations found in the usage of drugs for the two conditions.

Despite recent advances in therapeutic options, there remains an unmet need for treating patients with relapsed or refractory multiple myeloma, especially in those previously exposed or refractory to lenalidomide. This updated efficacy and safety analysis from the phase 3 CANDOR study compared carfilzomib, daratumumab, and dexamethasone (KdD) with carfilzomib and dexamethasone (Kd) in patients with relapsed or refractory multiple myeloma. In this updated analysis of the randomised, multicentre, open-label, phase 3 CANDOR study, patients (aged ≥18 years) with relapsed or refractory multiple myeloma, at least a partial response to between one and three previous therapies, and Eastern Cooperative Oncology Group performance status of 0–2, were recruited from 102 medical centres globally and randomly assigned (2:1) by interactive voice or web response software to receive KdD or Kd. Participants were stratified by disease stage, previous proteasome inhibitor or anti-CD38 antibody exposure, and number of previous therapies. All patients received intravenous infusions of carfilzomib twice per week at 56 mg/m2 (20 mg/m2 on days 1 and 2 during cycle 1) on days 1, 2, 8, 9, 15, and 16 of each 28-day cycle. Daratumumab (8 mg/kg) was administered intravenously on days 1 and 2 of cycle 1 and at 16 mg/kg weekly for the remaining doses of the first two cycles, then every 2 weeks for four cycles (cycles 3–6), and every 4 weeks thereafter. Patients received 40 mg dexamethasone weekly (20 mg for patients >75 years old). This analysis was a preplanned interim analysis for overall survival; however, at the time of data cutoff, overall survival data were not mature. The primary endpoint was progression-free survival. Here, we provide updated progression-free survival data, assessed centrally by Onyx Response Computer Algorithm in the intention-to-treat population, with 11 months additional follow-up. Adverse events were assessed in the safety population, which included all participants who received at least one dose of trial treatment. CANDOR is registered with ClinicalTrials.gov, NCT03158688, and is active but not recruiting. Between June 13, 2017, and June 25, 2018, 466 patients were enrolled, of whom 312 received KdD and 154 received Kd. At data cutoff (June 15, 2020), median follow-up was 27·8 months (IQR 25·6–29·5) for KdD and 27·0 months (13·2–28·6) for Kd. Median progression-free survival was 28·6 months (95% CI 22·7–not estimable [NE]) in the KdD group and 15·2 months (11·1–19·9) in the Kd group (hazard ratio 0·59 [95% CI 0·45–0·78], log-rank p<0·0001). Treatment-emergent adverse events in the safety population were consistent with the primary analysis. Grade 3 or worse treatment-emergent adverse events occurred in 268 (87%) patients in the KdD group and 116 (76%) in the Kd group; most commonly thrombocytopenia (76 [25%] vs 25 [16%], respectively), hypertension (65 [21%] vs 23 [15%]), pneumonia (54 [18%] vs 14 [9%]), and anaemia (53 [17%] vs 23 [15%]). Serious adverse events occurred in 194 (63%) patients with KdD and 76 (50%) with Kd. Adverse events leading to death occurred in 27 (9%) patients in the KdD group and seven (5%) in the Kd group; most commonly septic shock (five [2%] vs one (1%]) and pneumonia (four [1%] vs none). No new treatment-related deaths have occurred since the primary analysis. A clear, maintained progression-free survival benefit of KdD over Kd with longer follow-up was confirmed, making KdD an emerging standard-of-care for patients with relapsed or refractory multiple myeloma.

Lenalidomide and bortezomib frontline exposure has raised a growing need for novel treatments for patients with relapsed or refractory multiple myeloma. Carfilzomib in combination with daratumumab has shown substantial efficacy with tolerable safety in relapsed or refractory multiple myeloma in a phase 1 study. In this study, we aimed to compare the efficacy and safety of carfilzomib, dexamethasone, and daratumumab versus carfilzomib and dexamethasone in patients with relapsed or refractory multiple myeloma. In this randomised, multicentre, open-label, phase 3 study, 466 patients recruited from 102 sites across North America, Europe, Australia, and Asia with relapsed or refractory multiple myeloma were randomly assigned 2:1 to carfilzomib, dexamethasone, and daratumumab (KdD) or carfilzomib and dexamethasone (Kd). All patients received twice per week carfilzomib at 56 mg/m2 (20 mg/m2; days 1 and 2 during cycle 1). Daratumumab (8 mg/kg) was administered intravenously on days 1 and 2 of cycle 1 and at 16 mg/kg weekly for the remaining doses of the first two cycles, then every 2 weeks for four cycles (cycles 3–6), and every 4 weeks thereafter. Patients received 40 mg dexamethasone weekly (20 mg for patients ≥75 years old starting on the second week). The primary endpoint was progression-free survival assessed by intention to treat. Adverse events were assessed in the safety population. This trial (NCT03158688) is registered with ClinicalTrials.gov, and is active but not recruiting. Between June 13, 2017, and June 25, 2018, 466 patients of 569 assessed for eligibility were enrolled. After median follow-up of approximately 17 months, median progression-free survival was not reached in the KdD group versus 15·8 months in the Kd group (hazard ratio 0·63; 95% CI 0·46–0·85; p=0·0027). Median treatment duration was longer in the KdD versus the Kd group (70·1 vs 40·3 weeks). Grade 3 or higher adverse events were reported in 253 (82%) patients in the KdD group and 113 (74%) patients in the Kd group. The frequency of adverse events leading to treatment discontinuation was similar in both groups (KdD, 69 [22%]; Kd, 38 [25%]). KdD significantly prolonged progression-free survival versus Kd in patients with relapsed or refractory multiple myeloma and was associated with a favourable benefit–risk profile. Amgen.

Early life stress has been linked to increased methylation of the Nuclear Receptor Subfamily 3 Group C Member 1 (NR3C1) gene, which codes for the glucocorticoid receptor. Moreover, early life stress has been associated with substance use initiation at a younger age, a risk factor for developing substance use disorders. However, no studies to date have investigated whether NR3C1 methylation can predict substance use in young individuals. This study included adolescents 13–14 years of age that reported no history of substance use at baseline, (N = 1041; males = 46%). Participants contributed saliva DNA samples and were followed in middle adolescence as part of KUPOL, a prospective cohort study of 7th-grade students in Sweden. Outcome variables were self-reports of (i) recent use, (ii) lifetime use, and (iii) use duration of (a) alcohol, (b) tobacco products, (c) cannabis, or (d) any substance. Outcomes were measured annually for three consecutive years. The predictor variable was DNA methylation at the exon 1 F locus of NR3C1. Risk and rate ratios were calculated as measures of association, with or without adjustment for internalizing symptoms and parental psychiatric disorders. For a subset of individuals (N = 320), there were also morning and afternoon salivary cortisol measurements available that were analyzed in relation to NR3C1 methylation levels. Baseline NR3C1 hypermethylation associated with future self-reports of recent use and use duration of any substance, before and after adjustment for potential confounders. The overall estimates were attenuated when considering lifetime use. Sex-stratified analyses revealed the strongest association for cigarette use in males. Cortisol analyses revealed associations between NR3C1 methylation and morning cortisol levels. Findings from this study suggest that saliva NR3C1 hypermethylation can predict substance use in middle adolescence. Additional longitudinal studies are warranted to confirm these findings.

Tracking of clonal immunoglobulin V(D)J rearrangement sequences by next generation sequencing is highly sensitive for minimal residual disease in multiple myeloma. However, previous studies have found variable rates of V(D)J sequence identification at baseline, which could limit tracking. Here, we aimed to define the factors influencing the identification of clonal V(D)J sequences. Bone marrow mononuclear cells from 177 myeloma patients underwent V(D)J sequencing by the LymphoTrack assays (Invivoscribe). As a molecular control for tumor cell content, we sequenced the samples using our in-house myeloma panel myTYPE. V(D)J sequence clonality was identified in 81% of samples overall, as compared with 95% in samples where tumor-derived DNA was detectable by myTYPE. Clonality was detected more frequently in patients with lambda-restricted disease, mainly because of increased detection of kappa gene rearrangements. Finally, we describe how the tumor cell content of bone marrow aspirates decrease gradually in sequential pulls because of hemodilution: From the initial pull used for aspirate smear, to the final pull that is commonly used for research. In conclusion, baseline clonality detection rates of 95% or higher are feasible in multiple myeloma. Optimal performance depends on the use of good quality aspirates and/or subsequent tumor cell enrichment.
