Epidemiology of myasthenia gravis in Denmark, Finland and Sweden: a population-based observational study.

BACKGROUND: Incidence and prevalence rates of myasthenia gravis (MG) vary considerably across studies, and mortality risk is rarely addressed. We examined the prevalence and incidence rates, mortality and factors associated with mortality with MG. METHOD: This was a registry linkage study based on nationwide health and administrative registries of Denmark, Finland and Sweden (populations of 5.9, 5.6 and 10.5 million, respectively). Patients with MG were identified based on International Classification of Diseases codes from inpatient and outpatient specialised care registries. Yearly prevalence, incidence and mortality rates in relation to the total background population were calculated from 2000 to 2020 (study period). The causes of death and factors associated with mortality were addressed separately. RESULTS: The overall incidence of MG was 1.34 (95% CI 1.27 to 1.41), 1.68 (95% CI 1.60 to 1.75) and 1.62 (95% CI 1.56 to 1.68) per 100 000, and the overall prevalence per 100 000 was 18.56 (95% CI 18.31 to 18.81), 20.89 (95% CI 20.62 to 21.16) and 23.42 (95% CI 23.21 to 23.64) in Denmark, Finland and Sweden, respectively. The overall standardised mortality ratio (SMR) was 1.32 (95% CI 1.23 to 1.42) among patients with MG in Denmark, 1.23 (95% CI 1.15 to 1.33) in Finland, and 1.20 (95% CI 1.14 to 1.26) in Sweden, with higher SMR observed in women than men. Annual incidence and prevalence increased over time, whereas the SMR remained stable. The most common causes of death were MG, chronic ischaemic heart disease and acute myocardial infarction. CONCLUSIONS: This population-based study from three Nordic countries highlights the need for improved care of patients with MG, especially young women.

Utilization of anonymization techniques to create an external control arm for clinical trial data.

BACKGROUND: Subject-level real-world data (RWD) collected during daily healthcare practices are increasingly used in medical research to assess questions that cannot be addressed in the context of a randomized controlled trial (RCT). A novel application of RWD arises from the need to create external control arms (ECAs) for single-arm RCTs. In the analysis of ECAs against RCT data, there is an evident need to manage and analyze RCT data and RWD in the same technical environment. In the Nordic countries, legal requirements may require that the original subject-level data be anonymized, i.e., modified so that the risk to identify any individual is minimal. The aim of this study was to conduct initial exploration on how well pseudonymized and anonymized RWD perform in the creation of an ECA for an RCT. METHODS: This was a hybrid observational cohort study using clinical data from the control arm of the completed randomized phase II clinical trial (PACIFIC-AF) and RWD cohort from Finnish healthcare data sources. The initial pseudonymized RWD were anonymized within the (k, ε)-anonymity framework (a model for protecting individuals against identification). Propensity score matching and weighting methods were applied to the anonymized and pseudonymized RWD, to balance potential confounders against the RCT data. Descriptive statistics for the potential confounders and overall survival analyses were conducted prior to and after matching and weighting, using both the pseudonymized and anonymized RWD sets. RESULTS: Anonymization affected the baseline characteristics of potential confounders only marginally. The greatest difference was in the prevalence of chronic obstructive pulmonary disease (4.6% vs. 5.4% in the pseudonymized compared to the anonymized data, respectively). Moreover, the overall survival changed in anonymization by only 8% (95% CI 4-22%). Both the pseudonymized and anonymized RWD were able to produce matched ECAs for the RCT data. Anonymization after matching impacted overall survival analysis by 22% (95% CI -21-87%). CONCLUSIONS: Anonymization may be a viable technique for cases where flexible data transfer and sharing are required. As anonymization necessarily affects some aspects of the original data, further research and careful consideration of anonymization strategies are needed.

Comorbidities and Medication Use in Finnish Patients with Psoriasis: A Population-Based Registry Study.

Therapeutic options for psoriasis vulgaris have changed during recent decades with the introduction of biologics. Few nationwide studies are available on psoriasis treatment patterns, and those from Finland predate the use of biologics. The aim of this retrospective, population-based registry study was to identify patients with psoriasis vulgaris and their treatment patterns in the secondary care setting in Finland. The study cohort included 41,456 adults with a diagnosis of psoriasis vulgaris in the public secondary healthcare setting from 2012 through 2018. Data on comorbidities, pharmacotherapy, and phototherapy were collected from nationwide healthcare and drug registries. Patients in the cohort had a wide range of comorbidities, with 14.9% having psoriatic arthritis. Treatment was based largely on topical and conventional systemic medications. Conventional medications were used by 28.9% of patients, and methotrexate was the most common option (20.9%). Biologics were used by 7.3% of patients, mostly as second- and third-line treatment. The use of conventional systemic medications, topical treatments, and phototherapy decreased after the initiation of biologics. This study of psoriasis vulgaris in Finland provides a framework for the development of future care practices.

Effectiveness of mepolizumab in patients with severe eosinophilic asthma: results from real-world clinical practice in Finland.

OBJECTIVES: Mepolizumab treatment provides clinical benefits for patients with severe eosinophilic asthma in randomized controlled trials. However, real-world data for patients in Finland are lacking. METHODS: This retrospective, non-interventional, chart review study included patients with severe eosinophilic asthma ≥18 years of age initiating mepolizumab between January 1, 2016 and January 31, 2019 at three investigational sites in Finland. Patient characteristics during the 12 months prior to mepolizumab initiation (baseline) were recorded and primary and secondary endpoints included changes from baseline in disease outcomes during follow-up (up to 24 months following mepolizumab initiation). Exploratory endpoints included association between patient characteristics and exacerbation frequency/annual cumulative oral corticosteroid (OCS) dose. RESULTS: Overall, 51 patients were included (mean 17.8 months follow-up). At baseline, patients had a mean (standard deviation) blood eosinophil count of 550 (410) cells/µL; impaired lung function and health-related quality of life; poor symptom control; frequent exacerbations (2.78/year); and 90% were using OCS (mean: 9.80 mg/day). At the last follow-up visit, reductions from baseline in blood eosinophil count (84%) and fractional exhaled nitric oxide (26%) were observed, as were improvements in Asthma Quality of Life Questionnaire score (36%) and Asthma Control Test score (34%). Reductions in the mean number of annual exacerbations (82%) and mean daily OCS dose (39%) were also seen; reductions were observed even after adjustment for several patient baseline characteristics. CONCLUSIONS: Results are consistent with previous randomized clinical trials, indicating that Finnish patients experience clinically relevant improvements when treated with mepolizumab in real-world clinical practice.

The association of body mass index with quality of life and working ability: a Finnish population-based study.

PURPOSE: The impact of obesity on quality of life (QoL) and working ability vary in different dimensions. This study investigated the association of obesity with QoL and working ability in Finnish adults. Comorbidities as associative factors were also characterised. METHODS: This cross-sectional study included 4956 randomly selected adults. QoL (EUROHIS-QOL 8 total score and individual components), perceived physical and psychological working ability, and sick leave days were analysed in different body mass index (BMI) groups. Regression models were used to study the role of comorbidities as associative factors. RESULTS: EUROHIS-QOL 8 total score was significantly lower in BMI group 25.0-29.9 kg/m2 (4.01; 95% confidence interval 3.97-4.05), BMI 30.0-34.9 kg/m2 (3.85; 3.79-3.91), BMI 35.0-39.9 kg/m2 (3.75; 3.66-3.85), and BMI ≥ 40.0 kg/m2 (3.73; 3.46-4.00) compared to individuals with normal (18.5-24.9 kg/m2) BMI (4.08; 4.04-4.12). Individuals with obesity (BMI ≥ 30.0 kg/m2) rated their QoL lower than individuals with normal BMI in seven of the eight EUROHIS-QOL 8 components. A lesser proportion of individuals (53-73%) with obesity rated their physical working ability as very or fairly good compared to individuals with normal BMI (90%, p values < 0.001). The psychological working ability was rated as very or fairly good by 71-75% of individuals with obesity compared to 85% of individuals with normal BMI (p = 0.008 and p = 0.001 in individuals with BMI 30.0-34.9 and BMI 35.0-39.9 kg/m2, respectively). CONCLUSIONS: Obesity was negatively associated with both physical and psychological components of QoL, even after accounting for obesity-related comorbidities. Obesity treatment can benefit from a holistic approach that considers these multifaceted associations.

Incidence of second primary malignancies in metastatic castration-resistant prostate cancer: results from observational studies in three countries.

Aim: This reports some of the first incidence rate (IR) estimates of second primary malignancies (SPMs) in men with metastatic castration-resistant prostate cancer (mCRPC) in three countries. Patients & methods: Claims data from the German Pharmacoepidemiological Research Database; registry data from the Prostate Cancer Data Base Sweden; and combined registry-claims data from the US Surveillance, Epidemiology and End Results-Medicare database were analyzed to obtain overall survival and incidence of SPMs in men with mCRPC. Results: SPMs occurred in 308 German (n = 2360), 273 Swedish (n = 2849) and 172 US (n = 2234) men with mCRPC. IRs of SPMs were 79.0 (95% CI: 70.4-88.4), 101.7 (95% CI: 90.3-114.5) and 59 (95% CI: 50-68) per 1000 person-years in German, Swedish and US cohorts, respectively. Conclusion: These studies report some of the first IR estimates of SPMs in men with mCRPC, providing a historical risk estimate of SPM in this patient population.

Observational evidence from patients diagnosed with chronic lymphocytic leukaemia (CLL) in Finland between 2005-2015 show improved survival over time.

OBJECTIVES: We aimed to describe treatment patterns of chronic lymphocytic leukaemia (CLL) patients in routine practice settings, compare overall survival and time-to-next-treatment among patients treated in different time periods (2005-2008, 2009-2013, 2014-2015), and explore associated factors. METHODS: This retrospective cohort study included adult CLL patients from the Finnish Hematology Registry. RESULTS: In total, 124 and 64 CLL patients received first- and second-line treatments, respectively. The use of first- and second-line treatments with bendamustine-rituximab (BR) increased, while chlorambucil-based treatments decreased over time. Patients treated in more recent years showed a trend towards longer first- and second-line survival. A trend towards inferior overall survival was detected in first- and second-line treatment with B/BR. First-line time-to-next-treatment was longer for patients treated in the later years towards 2015, while second-line time-to-next-treatment did not improve over time. CONCLUSIONS: This study identified that improved treatment outcomes over time were likely influenced by patient characteristics and treatments, but also through other factors unexplored in this study. Hence, further research on the factors influencing patients' survival over time is needed. In particular, research on using B/BR in clinical practice is warranted.

Poor Quality of Warfarin Treatment Increases the Risk of All Types of Intracranial Hemorrhage in Atrial Fibrillation.

BACKGROUND: Intracranial hemorrhage (ICH) is a devastating complication of oral anticoagulation. The aim of this study was to describe the spectrum of ICH and to evaluate the association of warfarin control with the risk of ICH in a nationwide cohort of unselected atrial fibrillation (AF) patients. Methods and Results: The FinWAF is a retrospective registry-linkage study. Data were collected from several nationwide Finnish health-care registers and laboratory databases. The primary outcome was any ICH (traumatic or non-traumatic). The quality of warfarin therapy was assessed continuously by calculating the time in therapeutic range in a 60-day window (TTR60). Adjusted Cox proportional hazard models were used. A total of 53,953 patients were included (53% men; mean age, 73 years; mean follow-up, 2.94 years; mean TTR, 63%). In 129,684 patient-years, 1,196 patients had ICH (non-traumatic, 53.5%; traumatic, 43.6%; traumatic subdural, 38.6%); crude annual rate, 0.92%; 95% CI: 0.87-0.98). A lower TTR60 was significantly associated with higher risk of ICH (TTR60 ≤40% vs. TTR60 >80%; adjusted hazard ratio, 2.16; 95% CI: 1.83-2.54). Other variables independently associated with ICH included age >65 years, previous stroke, male sex, low hemoglobin, thrombocytopenia, elevated alanine aminotransferase, and previous bleeding other than ICH. CONCLUSIONS: Poor control of warfarin treatment was associated with elevated risk of ICH. Approximately half of the ICH were traumatic, mainly subdural.

Quality of warfarin therapy and risk of stroke, bleeding, and mortality among patients with atrial fibrillation: results from the nationwide FinWAF Registry.

PURPOSE: The most important management strategy in atrial fibrillation (AF) patients is preventing stroke with oral anticoagulants. Warfarin is still used as a first-line anticoagulant, although non-vitamin K antagonist oral anticoagulants are currently recommended to manage AF. Using a large, unselected national sample of AF patients, we evaluated the relationships between quality of warfarin therapy and the risks of thromboembolism, bleeding complications, and mortality. METHODS: The nationwide FinWAF study included 54 568 AF patients taking warfarin. Time in the therapeutic range (TTR) was calculated on a continuous basis using the Rosendaal method and international normalized ratio values over the previous 60 days. Adjusted Cox proportional hazard models were prepared for different TTR levels and major clinical end points. RESULTS: The mean age of patients was 73.1 years (standard deviation 10.8), and 47% were female. The mean follow-up time was 3.2 ± 1.6 years (median 3.4). In the TTR groups of ≤40%, 60-70%, 70-80%, and >80%, the annual risk of stroke was 9.3%, 4.7%, 4.6%, and 3.1%; bleeding events 7.5%, 4.5%, 4.3%, and 2.6%; and overall mortality 20.9%, 8.5%, 6.4%, and 3.1%, respectively. All differences among the TTR groups were highly significant (p < 0.001). CONCLUSIONS: The quality of warfarin treatment was strongly associated with the risk of stroke and the prognosis of AF patients. Patient outcomes continued to improve with increasing TTR values up to a TTR ≥80%; therefore, the target for the TTR should exceed 80% instead of the traditional range of at least 60-70%.

Estimation and interpretation of heterogeneous vaccine efficacy against recurrent infections.

Vaccine-induced protection may not be homogeneous across individuals. It is possible that a vaccine gives complete protection for a portion of individuals, while the rest acquire only incomplete (leaky) protection of varying magnitude. If vaccine efficacy is estimated under wrong assumptions about such individual level heterogeneity, the resulting estimates may be difficult to interpret. For instance, population-level predictions based on such estimates may be biased. We consider the problem of estimating heterogeneous vaccine efficacy against an infection that can be acquired multiple times (susceptible-infected-susceptible model). The estimation is based on a limited number of repeated measurements of the current status of each individual, a situation commonly encountered in practice. We investigate how the placement of consecutive samples affects the estimability and efficiency of vaccine efficacy parameters. The same sampling frequency may not be optimal for efficient estimation of all components of heterogeneous vaccine protection. However, we suggest practical guidelines allowing estimation of all components. For situations in which the estimability of individual components fails, we suggest to use summary measures of vaccine efficacy.

Healthcare resource utilization patterns in psoriasis patients using biologic and conventional treatments in Finland.

Introduction and aim: Psoriasis vulgaris is associated with a significant healthcare burden, which increases over time as the disease progresses. The aim of this retrospective, population-based registry study was to characterize healthcare resource utilization (HCRU) in patients with psoriasis using biologics and oral immunosuppressants (conventionals) in Finland. Materials and methods: The study cohort included all patients with a diagnosis of psoriasis vulgaris in the secondary healthcare setting between 2012-2018, who initiated a biologic (n=1,297) or conventional (n=4,753) treatment between 2013-2017. Data on primary and secondary HCRU were collected from nationwide healthcare registries. Results: The results indicated a remarkable decrease in contacts with a dermatologist after the treatment initiation among patients starting biologic (mean annual number of contacts 5.4 per person before and 2.3 after the initiation), but not conventional (3.3 and 3.2) treatment. For conventional starters there was a high level of contacts with a dermatologist surrounding times of treatment switching, which was not observed for biologic starters. Conclusion: Overall, primary and other secondary care contacts did not decrease after the initiation or switch of treatment. The results highlight the importance of thorough consideration of the most optimal treatment alternatives, considering the overall disease burden to patients and healthcare systems.

Comorbidity Burden in Severe and Nonsevere Asthma: A Nationwide Observational Study (FINASTHMA).

BACKGROUND: Asthma, affecting more than 330 million people worldwide, is associated with a high level of morbidity, mortality, and socioeconomic costs. OBJECTIVE: In this cross-sectional study, we analyzed the comorbidity burden in patients with severe asthma compared with nonsevere asthma and investigated the role of corticosteroid use on the risk of comorbidities. METHODS: All adults (≥18 y) with a diagnosis of asthma (International Classification of Diseases-10th revision code J45.x) between 2014 and 2017 were identified and data were collected until 2018 from Finnish nationwide registers. Asthma was defined as continuously or transiently severe or nonsevere based on annual dispensed inhaled corticosteroids (ICS), oral corticosteroids (OCS), and hospitalizations. RESULTS: Of 193,730 adult identified patients diagnosed with asthma, 86.3% had nonsevere, 8.1% transiently severe, and 5.6% continuously severe asthma. Excess prevalence of pneumonia was observed in continuously (22%) and transiently severe (14%) compared with nonsevere patients after adjusting for age and sex. Cataract, osteoporosis, obesity, heart failure, and atrial fibrillation were also more frequent in severe asthma patients. The ICS and/or OCS use contributed to the risk of several comorbidities in a dose-dependent manner, particularly pneumonia, osteoporosis, obesity, heart failure, and atrial fibrillation. High OCS use and the presence of comorbidities were associated with increased health care resource use. CONCLUSIONS: Patients with severe asthma have a high burden of comorbidities, especially pneumonia. Many of the comorbidities have a strong dose-dependent association with ICS and OCS treatment, suggesting that corticosteroid doses should be carefully evaluated in clinical practice.

Competition between Streptococcus pneumoniae strains: implications for vaccine-induced replacement in colonization and disease.

BACKGROUND: Vaccine-induced replacement by nonvaccine serotypes in pneumococcal colonization and disease poses a threat to the long-term effectiveness of pneumococcal vaccination. One of the main drivers for serotype replacement is likely to be the competitive interactions between pneumococcal serotypes. METHODS: We used longitudinal datasets of pneumococcal colonization among infants (American Indian and The Gambia) and toddlers (Denmark) to study the strength and mechanism of competition between pneumococcal serotypes. We characterized the strength of competition as the relative reduction in the expected time spent colonized with two serotypes (double colonization) as compared with colonization with no competition. We also assessed the mechanism of competition, that is, whether reduction in double colonization is due to reduced rate of acquisition or enhanced clearance of colonization. The three datasets were analyzed assuming both perfect (100%) and imperfect (50%) sensitivity in detection of double colonization. RESULTS: Each dataset showed strong between-serotype competition, and competition in acquisition was clearly identified. These findings remained in the secondary analysis assuming only 50% sensitivity to detect double colonization. Inferences about enhanced clearance due to competition were susceptible to the assumed sensitivity of detection. CONCLUSIONS: Strong competition between pneumococcal serotypes can explain the prompt replacement by the nonvaccine serotypes in vaccinated persons and populations. The main mechanism of between-serotype interaction was identified as competition in acquisition, which suggests that replacement in pneumococcal disease depends largely on propensities of the replacing serotypes to cause disease through acquisition of colonization.

Early start of anti-dementia medication is associated with lower health and social care costs in Alzheimer´s patients: a Finnish nationwide register study.

OBJECTIVES: To evaluate the association between health and social care costs and early start of anti-dementia medication in a nationwide cohort of Finnish Alzheimer's disease (AD) patients. METHODS: The cohort included 7454 Finnish AD patients who had their first AD diagnosis in 2012 and lived at home at the time of diagnosis. Data were collected retrospectively from the Finnish national health and social care registers. The primary outcome was 2-year cumulative direct costs after the incident AD diagnosis. The exploratory variable was early anti-dementia medication start (anti-dementia medication started within 3 months of the incident AD diagnosis). Sociodemographic variables, admission to 24-h care and care intensity level, as well as comorbidities were considered as adjusting variables. RESULTS: Of all patients, 88.9% started AD medication within 3 months of diagnosis. The 2-year cumulative costs were €30,787 and €40,484 per patient for early and late starters, respectively. When adjusted for possible confounders, early start of anti-dementia medication was associated with 26.5% lower 2-year cumulative costs compared to late starters (relative cost 0.735; p < 0.001). CONCLUSIONS: Early diagnosis and start of anti-dementia medication is important for managing the costs of increasing number of AD patients.

The association between body mass index groups and metabolic comorbidities with healthcare and medication costs: a nationwide biobank and registry study in Finland.

BACKGROUND: The increasing prevalence of obesity imposes a significant cost burden on individuals and societies worldwide. OBJECTIVE: In this nationally representative study, the association between body mass index (BMI) groups and the number of metabolic comorbidities (MetC) with total direct costs was investigated in the Finnish population. STUDY DESIGN, SETTING, AND PARTICIPANTS: The study cohort included 5,587 adults with BMI ≥18.5 kg/m2 who participated in the cross-sectional FinHealth 2017 health examination survey conducted by the Finnish Institute for Health and Welfare. Data on healthcare resource utilization (HCRU) and drug purchases were collected from national healthcare and drug registers. MAIN OUTCOME MEASURE: The primary outcome was total direct costs (costs of primary and secondary HCRU and prescription medications). RESULTS: Class I (BMI 30.0-34.9 kg/m2) and class II - III (BMI ≥35.0 kg/m2) obesity were associated with 43% and 40% higher age- and sex-adjusted direct costs, respectively, compared with normal weight, mainly driven by a steeply increased comorbidity in the higher BMI groups. In all BMI groups combined, individuals with ≥2 MetCs comprised 39% of the total study population and 60% of the total costs. CONCLUSION: To manage the cost burden of obesity, treatment should be given equal consideration as other chronic diseases, and BMIs ≥30.0 kg/m2 should be considered in treatment decisions.

Obesity and metabolic state are associated with increased healthcare resource and medication use and costs: a Finnish population-based study.

AIM: To characterize healthcare resource (HCRU) and medication use and associated costs in individuals with obesity compared with individuals with normal weight or overweight in a population-based cohort of Finnish adults. The association between metabolic state and direct costs was also assessed. METHODS: The study cohort included 5587 randomly selected individuals who participated in the national FinHealth 2017 health examination survey. Data on healthcare visits and hospital stays, including diagnoses (ICD-10), and purchases and costs of prescription medicines were collected from the nationwide registers by the Finnish Institute for Health and Welfare and Social Insurance Institution of Finland. The healthcare costs were calculated based on standard unit costs reported by the Finnish Institute for Health and Welfare. RESULTS: The total annual direct costs were €2665 (SD €5673) and €1799 (SD €3874) per person with obesity and with normal weight or overweight, respectively. Obesity was associated with significantly increased total direct (age- and sex-adjusted cost rate ratio, RR, 1.356; p < 0.001), HCRU-related (1.273; p = 0.002), and medication (1.669; p < 0.001) costs. A vast majority (90%) of individuals with obesity were classified as metabolically unhealthy based on clinical measurements. The metabolically unhealthy state was associated with increased costs in individuals with obesity but not in individuals with normal weight or overweight. CONCLUSION: Obesity is associated with a significant and complex direct cost burden to society, arising primarily from increased comorbidity. Metabolically healthy obesity is uncommon and obesity prevention and timely treatment should be of high priority to tackle the increasing burden of obesity.

Real-world treatment outcomes and safety of natalizumab in Finnish multiple sclerosis patients.

Objectives: The primary objective was to evaluate long-term treatment persistence and safety of natalizumab in Finnish multiple sclerosis patients. The secondary objectives were to assess patient characteristics, use of natalizumab-related safety protocol, and treatment persistence in patients with different anti-John Cunningham virus antibody statuses (John Cunningham virus status). Materials & Methods: All adult multiple sclerosis patients in the Finnish multiple sclerosis register who started natalizumab between 1/2006 and 12/2018 were included in this study and followed retrospectively until treatment discontinuation or end of follow-up (12/2019). Results: In total, 850 patients were included. Median duration of natalizumab treatment was 7.8 years in John Cunningham virus negative (n = 229) and 2.1 years in John Cunningham virus positive patients (n = 115; p < 0.001). The most common cause for treatment discontinuation was John Cunningham virus positivity. After natalizumab discontinuation, patients who had a washout duration of less than 6 weeks had fewer relapses during the first 6 months (p = 0.012) and 12 months (p = 0.005) compared with patients who had a washout duration of over 6 weeks. During the median follow-up of 3.6 years, 76% of patients remained stable or improved on their Expanded Disability Status Scale. Conclusions: Treatment persistence was very high among John Cunningham virus negative patients. The study supports long-term effectiveness of natalizumab and a washout duration of less than 6 weeks after discontinuation.

Real-world experience of novel multiple myeloma treatments in a large, single-center cohort in Finland.

In this single-center study, we aimed to describe the characteristics, treatment patterns, and outcomes of patients with multiple myeloma (MM) following treatment with bortezomib, carfilzomib, daratumumab, ixazomib, lenalidomide or pomalidomide-based regimens. Data were collected retrospectively from a study cohort of patients receiving a MM treatment in the Hospital District of Helsinki and Uusimaa (HUS) in Finland between 2016-2020. In total, 472 patients were included in the study. Median age was 68.2 years and nearly 25% had a high cytogenetic risk according to the International Myeloma Working Group categorization. In 2018-2020, the spectrum of regimens used as third- or later-line therapy was notably broader than in 2016-2017. The overall response rates for patients who received the most novel regimens (available ≤ 5 years) in second or third line of therapy (n = 67/430) and fourth line or later (n = 78/151) were 53.3% and 25.0%, respectively. In this real-world MM patient cohort, the response rates for these novel agents were lower compared to those reported in clinical trials. Given the higher cytogenetic risk profile and more advanced disease stage at the time when treated with novel agents, patients could have benefited from effective novel therapies earlier in their treatment pathway. What is the NEW aspect of your work? (ONE sentence) This study characterized the treatment of Finnish multiple myeloma patients during the era of most novel therapies (after 2016) and also included information on the cytogenetic risk profile of this real-world population.What is the CENTRAL finding of your work?

(ONE sentence) Given the high cytogenetic risk profile and advanced disease stage at the time when treated with novel agents, patients could have benefited from effective novel therapies earlier in their treatment pathway.

Factors and their weight in reducing life expectancy in schizophrenia.

BACKGROUND: Schizophrenia is associated with a wide range of socioeconomic and health-related problems, as well as 10-25 potential life-years lost. While lifestyle choices, comorbidities, and choice of medication are associated with schizophrenia disease burden and mortality, real-world evidence on the impact of these factors on expected life-years among patients with schizophrenia is limited. METHODS: In this study, register-based, nationwide data from patients with schizophrenia in Finland during 1972-2015 were analysed to determine influential factors associated with mortality and to demonstrate their impact on expected life-years in patients with schizophrenia. RESULTS: Factors reducing all-cause mortality were use of antipsychotics: HR 0.46 (95 % CI: 0.45, 0.47), ever use of lipid-modifying agents: HR 0.71 (95 % CI 0.68, 0.73), antidepressants HR 0.87 (95 % CI 0.85, 0.90), and lithium HR 0.90 (95 % CI 0.86, 0.95). Factors increasing all-cause mortality were cardiovascular disease: HR 2.41 (95 % CI: 2.34, 2.49), liver disease: HR 1.98 (95 % CI: 1.78, 2.21), renal disease: HR 1.63 (95 % CI:1.56, 1.70), diabetes: HR 1.40 (95 % C:1.35, 1.45), history of switching antipsychotics: HR 1.39 (95 % CI: 1.35, 1.44), longer duration of previous hospitalisations HR 1.96 (95 % CI: 1.90, 2.02), history of substance abuse HR 1.38 (95 % CI: 1.30, 1.46), and ever use of benzodiazepines HR 1.12 (95 % CI: 1.09, 1.16). CONCLUSIONS: The results from this study could serve to motivate clinicians to support and encourage patients to adhere to antipsychotic treatment and achieve a healthier lifestyle, which could, in turn, increase the expected life-years of patients with schizophrenia.

Early Start of Anti-Dementia Medication Delays Transition to 24-Hour Care in Alzheimer's Disease Patients: A Finnish Nationwide Cohort Study.

BACKGROUND: Dementia is one of the strongest predictors of admission to a 24-hour care facility among older people, and 24-hour care is the major cost of Alzheimer's disease (AD). OBJECTIVE: The aim of this study was to evaluate the association of early start of anti-dementia medication and other predisposing factors with 2-year risk of transition to 24-hour care in the nationwide cohort of Finnish AD patients. METHODS: This was a retrospective, non-interventional study based on individual-level data from Finnish national health and social care registers. The incident cohort included 7,454 AD patients (ICD-10, G30) comprised of two subgroups: those living unassisted at home (n = 5,002), and those receiving professional home care (n = 2,452). The primary outcome was admission to a 24-hour care facility. Exploratory variables were early versus late anti-dementia medication start, sociodemographic variables, care intensity level, and comorbidities. RESULTS: Early anti-dementia medication reduced the risk of admission to 24-hour care both in patients living unassisted at home, with a hazard ratio (HR) of 0.58 (p < 0.001), and those receiving professional home care (HR, 0.84; p = 0.039). Being unmarried (HR, 1.69; p < 0.001), having an informal caregiver (HR, 1.69; p = 0.003), or having a diagnosis of additional neurological disorder (HR, 1.68; p = 0.006) or hip fracture (HR, 1.61; p = 0.004) were associated with higher risk of admission to 24-hour care in patients living unassisted at home. CONCLUSION: To support living at home, early start of anti-dementia medication should be a high priority in newly diagnosed AD patients.
