Abstract Population isolates such as those in Finland benefit genetic research because deleterious alleles are often concentrated on a small number of low-frequency variants (0.1% ≤ minor allele frequency < 5%). These variants survived the founding bottleneck rather than being distributed over a large number of ultrarare variants. Although this effect is well established in Mendelian genetics, its value in common disease genetics is less explored 1,2 . FinnGen aims to study the genome and national health register data of 500,000 Finnish individuals. Given the relatively high median age of participants (63 years) and the substantial fraction of hospital-based recruitment, FinnGen is enriched for disease end points. Here we analyse data from 224,737 participants from FinnGen and study 15 diseases that have previously been investigated in large genome-wide association studies (GWASs). We also include meta-analyses of biobank data from Estonia and the United Kingdom. We identified 30 new associations, primarily low-frequency variants, enriched in the Finnish population. A GWAS of 1,932 diseases also identified 2,733 genome-wide significant associations (893 phenome-wide significant (PWS), P < 2.6 × 10 –11 ) at 2,496 (771 PWS) independent loci with 807 (247 PWS) end points. Among these, fine-mapping implicated 148 (73 PWS) coding variants associated with 83 (42 PWS) end points. Moreover, 91 (47 PWS) had an allele frequency of <5% in non-Finnish European individuals, of which 62 (32 PWS) were enriched by more than twofold in Finland. These findings demonstrate the power of bottlenecked populations to find entry points into the biology of common diseases through low-frequency, high impact variants.

BACKGROUND: Nucleoside analogues against herpes simplex virus (HSV) have been shown to suppress shedding of HSV type 2 (HSV-2) on genital mucosal surfaces and may prevent sexual transmission of HSV. METHODS: We followed 1484 immunocompetent, heterosexual, monogamous couples: one with clinically symptomatic genital HSV-2 and one susceptible to HSV-2. The partners with HSV-2 infection were randomly assigned to receive either 500 mg of valacyclovir once daily or placebo for eight months. The susceptible partner was evaluated monthly for clinical signs and symptoms of genital herpes. Source partners were followed for recurrences of genital herpes; 89 were enrolled in a substudy of HSV-2 mucosal shedding. Both partners were counseled on safer sex and were offered condoms at each visit. The predefined primary end point was the reduction in transmission of symptomatic genital herpes. RESULTS: Clinically symptomatic HSV-2 infection developed in 4 of 743 susceptible partners who were given valacyclovir, as compared with 16 of 741 who were given placebo (hazard ratio, 0.25; 95 percent confidence interval, 0.08 to 0.75; P=0.008). Overall, acquisition of HSV-2 was observed in 14 of the susceptible partners who received valacyclovir (1.9 percent), as compared with 27 (3.6 percent) who received placebo (hazard ratio, 0.52; 95 percent confidence interval, 0.27 to 0.99; P=0.04). HSV DNA was detected in samples of genital secretions on 2.9 percent of the days among the HSV-2-infected (source) partners who received valacyclovir, as compared with 10.8 percent of the days among those who received placebo (P<0.001). The mean rates of recurrence were 0.11 per month and 0.40 per month, respectively (P<0.001). CONCLUSIONS: Once-daily suppressive therapy with valacyclovir significantly reduces the risk of transmission of genital herpes among heterosexual, HSV-2-discordant couples.

The Ozone Monitoring Instrument (OMI) flies on NASA's Earth Observing System AURA satellite, launched in July 2004. OMI is an ultraviolet/visible (UV/VIS) nadir solar backscatter spectrometer, which provides nearly global coverage in one day, with a spatial resolution of 13 km/spl times/24 km. Trace gases measured include O/sub 3/, NO/sub 2/, SO/sub 2/, HCHO, BrO, and OClO. In addition OMI measures aerosol characteristics, cloud top heights and cloud coverage, and UV irradiance at the surface. OMI's unique capabilities for measuring important trace gases with daily global coverage and a small footprint will make a major contribution to our understanding of stratospheric and tropospheric chemistry and climate change along with Aura's other three instruments. OMI's high spatial resolution enables detection of air pollution at urban scales. Total Ozone Mapping Spectrometer and differential optical absorption spectroscopy heritage algorithms, as well as new ones developed by the international (Dutch, Finnish, and U.S.) OMI science team, are used to derive OMI's advanced backscatter data products. In addition to providing data for Aura's prime objectives, OMI will provide near-real-time data for operational agencies in Europe and the U.S. Examples of OMI's unique capabilities are presented in this paper.

ABSTRACT Population isolates such as Finland provide benefits in genetic studies because the allelic spectrum of damaging alleles in any gene is often concentrated on a small number of low-frequency variants (0.1% ≤ minor allele frequency &lt; 5%), which survived the founding bottleneck, as opposed to being distributed over a much larger number of ultra--rare variants. While this advantage is well-- established in Mendelian genetics, its value in common disease genetics has been less explored. FinnGen aims to study the genome and national health register data of 500,000 Finns, already reaching 224,737 genotyped and phenotyped participants. Given the relatively high median age of participants (63 years) and dominance of hospital-based recruitment, FinnGen is enriched for many disease endpoints often underrepresented in population-based studies (e.g., rarer immune-mediated diseases and late onset degenerative and ophthalmologic endpoints). We report here a genome-wide association study (GWAS) of 1,932 clinical endpoints defined from nationwide health registries. We identify genome--wide significant associations at 2,491 independent loci. Among these, finemapping implicates 148 putatively causal coding variants associated with 202 endpoints, 104 with low allele frequency (AF&lt;10%) of which 62 were over two-fold enriched in Finland. We studied a benchmark set of 15 diseases that had previously been investigated in large genome-wide association studies. FinnGen discovery analyses were meta-analysed in Estonian and UK biobanks. We identify 30 novel associations, primarily low-frequency variants strongly enriched, in or specific to, the Finnish population and Uralic language family neighbors in Estonia and Russia. These findings demonstrate the power of bottlenecked populations to find unique entry points into the biology of common diseases through low-frequency, high impact variants. Such high impact variants have a potential to contribute to medical translation including drug discovery.

BackgroundAnti–IL-5 therapy is a potential treatment for patients with hypereosinophilic syndrome (HES), although its clinical efficacy is unclear.ObjectiveWe sought to investigate the clinical efficacy and safety of mepolizumab versus placebo in patients with HES.MethodsThis randomized, multicenter, double-blind, placebo-controlled, phase III trial was conducted across 39 centers in 13 countries. Eligible patients had FIP1L1-PDGFRA-negative HES, experienced 2 or more flares (worsening of HES-related symptoms or blood eosinophil count requiring therapeutic escalation) in the previous 12 months, and had a screening blood eosinophil count greater than or equal to 1000 cells/μL. Patients were randomized (1:1) to subcutaneous mepolizumab (300 mg) or placebo every 4 weeks for 32 weeks, plus existing HES therapy. The primary outcome was the proportion of patients with 1 or more flares (worsening of HES-related symptoms necessitating therapy escalation or ≥2 courses of blinded rescue oral corticosteroids) during the study; in addition, patients who withdrew early from the study were counted as having a flare. Safety end points were also assessed.ResultsThe proportion of patients experiencing 1 or more flares/withdrawing from the study was 50% lower with mepolizumab versus placebo (15 of 54 [28%] vs 30 of 54 [56%]; P = .002). Logistic regression analysis was consistent with the primary analysis (odds ratio, 0.28; 95% CI, 0.12-0.64; P = .003). Similar proportions of patients in the mepolizumab and placebo groups experienced on-treatment adverse events (48 of 54 [89%] vs 47 of 54 [87%]).ConclusionsCompared with placebo, mepolizumab significantly reduced the occurrence of flares in patients with HES, with no new safety signals identified.

The Ozone Monitoring Instrument (OMI) was launched on July 15, 2004 on the National Aeronautics and Space Administration's Earth Observing System Aura satellite. The OMI instrument is an ultraviolet-visible imaging spectrograph that uses two-dimensional charge-coupled device detectors to register both the spectrum and the swath perpendicular to the flight direction with a 115/spl deg/ wide swath, which enables global daily ground coverage with high spatial resolution. This paper presents the OMI design and discusses the main performance and calibration features and results.

Effective treatment of inflammatory diseases is often challenging owing to their heterogeneous pathophysiology. Understanding of the underlying disease mechanisms is improving and it is now clear that eosinophils play a complex pathophysiological role in a broad range of type 2 inflammatory diseases. Standard of care for these conditions often still includes oral corticosteroids (OCS) and/or cytotoxic immune therapies, which are associated with debilitating side effects. Selective, biological eosinophil-reducing agents provide treatment options that improve clinical symptoms associated with eosinophilic inflammation and reduce OCS use. Mepolizumab is a humanized monoclonal antibody that binds to and neutralizes interleukin-5, the major cytokine involved in eosinophil proliferation, activation, and survival. Mepolizumab is approved for the treatment of severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis and hypereosinophilic syndrome. Additionally, the efficacy of add-on mepolizumab has been observed in patients with severe chronic rhinosinusitis with nasal polyposis and chronic obstructive pulmonary disease with an eosinophilic phenotype. Here, we review the development, approval, and real-world effectiveness of mepolizumab for the treatment of patients with severe eosinophilic asthma, from the DREAM to REALITI-A studies, and describe how knowledge from this journey extended to the use of mepolizumab and other biologics across a broad spectrum of eosinophilic diseases.

AIM: As a consequence of the improved survival of patients and of cost-effectiveness requirements for new treatments, health-related quality of life (HRQoL) issues have gained increasing attention in colorectal cancer (CRC). This cross-sectional study assesses HRQoL in several health states of CRC and explores factors influencing HRQoL. METHOD: Five hundred and eight Finnish CRC patients (aged 26-96 years; colon cancer 56%; women 47%) assessed their HRQoL using generic 15D and EQ-5D and cancer-specific EORTC QLQ-C30 questionnaires. Patients were divided into five groups: primary treatment, rehabilitation, remission, metastatic disease and palliative care. The patients' HRQoL was compared with population reference values. Multivariate modelling was used to find factors associated with HRQoL scores. RESULTS: The HRQoL of CRC patients is fairly good and comparable with that of the standardized general population except for those under palliative care. The mean 15D score of patients in the primary treatment group was 0.889 (95% CI 0.869-0.914), in rehabilitation 0.877 (0.855-0.907), in remission 0.886 (0.875-0.903), in metastatic disease 0.860 (0.844-0.878) and in palliative care 0.758 (0.716-0.808). The respective EQ-5D scores were 0.760 (0.699-0.823), 0.835 (0.777-0.881), 0.850 (0.828-0.882), 0.820 (0.783-0.858) and 0.643 (0.546-0.747). Multivariate analysis showed that fatigue, pain, age and financial difficulties had a marked negative impact on HRQoL. CONCLUSION: The mean HRQoL scores of CRC patients varied considerably depending on the HRQoL instrument used, but remained surprisingly good up to the palliative stage. In addition to age- and cancer-related symptoms, financial difficulties also had a clear negative impact on HRQoL, which needs to be taken into consideration when supporting patient HRQoL.

BackgroundPatients with severe asthma may require maintenance oral corticosteroids (mOCS) for disease control as well as systemic corticosteroid (SCS) bursts for clinically significant exacerbations. However, mOCS and SCS use are associated with adverse effects, which increases patient disease burden.ObjectiveTo assess the real-world corticosteroid-sparing effect of mepolizumab in patients with severe asthma.MethodsREALITI-A was a 24-month international, prospective, observational cohort study involving 84 centers across Europe, Canada, and the United States, with a 1-year pre-post mepolizumab treatment preplanned interim analysis. A total of 822 adults with a clinical diagnosis of asthma and a physician decision to initiate mepolizumab treatment (100 mg subcutaneously) were included. End points included daily mOCS dose at baseline (penultimate 28 days of pretreatment) and 1 year after treatment; percent reduction from baseline in mOCS dose; patients discontinuing mOCS 1 year after treatment; and the rate of clinically significant exacerbations (those requiring OCS for 3 days or more [or parenteral administration], emergency room visit, and/or hospital admission) before and after treatment.ResultsA total of 319 patients received mOCS at baseline (median [interquartile range]: 10.0 [5.0-15.0] mg/d). At 1 year after treatment, median mOCS dose was reduced by 75% (2.5 [0.0-5.0] mg/d); 64% of patients had a reduction in mOCS dose of 50% or greater compared with baseline and 43% discontinued mOCS. Clinically significant exacerbations decreased between pretreatment and posttreatment (rate ratio [95% confidence interval] 0.29 [0.26-0.32]; P < .001).ConclusionThis 1-year analysis demonstrates that real-world mepolizumab treatment is clinically effective in patients with severe asthma, providing disease control while reducing the need for mOCS and SCS bursts.

BACKGROUND: Booster vaccination against tetanus and diphtheria at 10-year intervals is commonly recommended. Reduced antigen content diphtheria and tetanus toxoids and acellular pertussis (dTpa) vaccines developed for booster vaccination of preschool children, adolescents, and adults are licensed for once-in-a-lifetime use in most countries. Objective. To evaluate decennial administration of a dTpa vaccine. Methods. Young adults vaccinated with dTpa or diphtheria and tetanus toxoids followed by acellular pertussis (DT+ap) 1 month later in a clinical trial 10 years previously received 1 dTpa dose. Blood samples were taken before and 1 month after vaccination. Antibody concentrations against vaccine antigens were measured by enzyme-linked immunosorbent assay. Solicited and unsolicited symptoms and serious adverse events were recorded. RESULTS: Eighty-two individuals were enrolled in the study. In the 75 individuals who had received the dTpa vaccine 10 years previously, prevaccination seroprotection or seropositivity rates were 98.8% (diphtheria), 97.5% (tetanus), 64.6% (pertussis toxoid), 100% (filamentous hemagglutinin), and 96.3% (pertactin). One month after the second booster, all study participants were seroprotected or seropositive against all vaccine antigens. Antibody concentrations increased by a similar magnitude as 10 years previously. During the 4-day follow-up, 9.9% of participants recorded grade 3 pain; 17.3% and 18.5% recorded redness and swelling of 50 mm or larger, respectively; and 8.6% recorded fever (temperature, 37.5 degrees C). No serious adverse events were considered causally related to the vaccine. CONCLUSIONS: A second dTpa booster was highly immunogenic and well tolerated in this population of young adults. This study supports the use of this vaccine as a decennial booster. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00610168 .

UNLABELLED: After administering the 10-valent pneumococcal polysaccharide nontypeable Haemophilus influenzae protein D-conjugated vaccine (PHiD-CV) to children aged 2-18 months, we observed a reduction in vaccine-type nasopharyngeal carriage, resulting in a reduction of overall pneumococcal nasopharyngeal carriage, which may be important for indirect vaccine effects. We noted a trend toward reduction of acute otitis media. BACKGROUND: This trial (ClinicalTrials.gov identifier NCT00839254), nested within a cluster-randomized double-blind invasive pneumococcal disease effectiveness study in Finland (ClinicalTrials.gov identifier NCT00861380), assessed the effectiveness of the 10-valent pneumococcal polysaccharide nontypeable Haemophilus influenzae protein D-conjugated vaccine (PHiD-CV or PCV10) against bacterial nasopharyngeal carriage and acute otitis media (AOM). METHODS: Infants (aged 6 weeks to 6 months) received the PHiD-CV or a control vaccine (hepatitis B) (schedule 3+1 or 2+1). Nasopharyngeal swabs were collected at 4 time points post-vaccination from all of the infants and at pre-vaccination from a subset. Parent-reported physician-diagnosed AOM was assessed from first vaccination until last contact (mean follow-up, 18 months). Vaccine effectiveness (VE) was derived as (1 - relative risk)*100, accounting for cluster design in AOM analysis. Significant VE was assessed descriptively (positive lower limit of the non-adjusted 95% confidence interval [CI]). RESULTS: The vaccinated cohort included 5093 infants for carriage assessment and 4117 infants for AOM assessment. Both schedules decreased vaccine-serotype carriage, with a trend toward a lesser effect from the 2+1 schedule ( VE across timpoints 19%-56% [3+1] and 1%-38% [2+1]). Trends toward reduced pneumococcal carriage (predominantly vaccine serotypes 6B, 14, 19F, and 23F), decreased carriage of vaccine-related serotype 19A, and small increases at later time points (ages 14-15 months) in non-vaccine-serotype carriage were observed. No effects on nontypeable Haemophilus influenzae, Staphylococcus aureus, or Moraxella catarrhalis carriage were observed. There were non-significant trends toward a reduction in the number of infants reporting AOM episodes (VE 3+1: 6.1% [95% CI, -2.7% to 14.1%] and 2+1: 7.4% [-2.8% to 16.6%]) and all AOM episodes (VE 3+1: 2.8% [-9.5% to 13.9%] and 2+1: 10.2% [-4.1% to 22.9%]). PHiD-CV was immunogenic and had an acceptable safety profile. CONCLUSIONS: We observed reduced vaccine-type pneumococcal carriage, a limited increase in non-vaccine-type carriage, and a trend toward AOM reduction.

BACKGROUND: With new treatment options, the prognosis of prostate cancer (PCa) has improved in recent decades, and health-related quality of life (HRQoL) has become an important outcome of treatment. HRQoL scores are also essential for health economic analyses concerning treatment options for the disease. This study assesses HRQoL scores in different health states of PCa, compares the results obtained by different HRQoL instruments, compares the HRQoL of PCa patients with that of the general population, and explores factors associated with the resultant HRQoL scores. MATERIAL AND METHODS: An observational cross-sectional study among PCa patients in the Helsinki and Uusimaa Hospital District between September 2009 and December 2010. A total of 630 PCa patients (aged 43-92) assessed their HRQoL with the generic 15D and EQ-5D, as well as the cancer-specific EORTC QLQ-C30 questionnaires. Patients were divided into five mutually exclusive groups based on disease state: Loc1 (local disease, first six months after diagnosis; n = 47), Loc2 (local disease, 0.5-1.5 years after diagnosis or recurrence; n = 158), Loc3 (local disease, more than 1.5 years after diagnosis; n = 317), Metastatic (after detection of metastases; n = 89) and Palliative care (n = 19). Multivariate analysis served to evaluate the factors associated with the HRQoL scores. RESULTS: The utility scores were highest at baseline. Markedly impaired HRQoL was seen first at the more advanced states of the disease. All HRQoL instruments studied were consistent in all states of the disease, yet the HRQoL scores obtained varied widely. Symptoms of fatigue and pain, and background variables of financial difficulties and age were the most important factors associated with poor HRQoL. CONCLUSIONS: All instruments provided valuable insight into PCa patients' overall HRQoL. Management of cancer-related symptoms is important in maintaining patients' HRQoL, but more attention should also focus on financial difficulties.

BACKGROUND: GSK3368715, a first-in-class, reversible inhibitor of type I protein methyltransferases (PRMTs) demonstrated anticancer activity in preclinical studies. This Phase 1 study (NCT03666988) evaluated safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of GSK3368715 in adults with advanced-stage solid tumors. METHODS: In part 1, escalating doses of oral once-daily GSK3368715 (50, 100, and 200 mg) were evaluated. Enrollment was paused at 200 mg following a higher-than-expected incidence of thromboembolic events (TEEs) among the first 19 participants, resuming under a protocol amendment starting at 100 mg. Part 2 (to evaluate preliminary efficacy) was not initiated. RESULTS: Dose-limiting toxicities were reported in 3/12 (25%) patients at 200 mg. Nine of 31 (29%) patients across dose groups experienced 12 TEEs (8 grade 3 events and 1 grade 5 pulmonary embolism). Best response achieved was stable disease, occurring in 9/31 (29%) patients. Following single and repeat dosing, GSK3368715 maximum plasma concentration was reached within 1 h post dosing. Target engagement was observed in the blood, but was modest and variable in tumor biopsies at 100 mg. CONCLUSION: Based on higher-than-expected incidence of TEEs, limited target engagement at lower doses, and lack of observed clinical efficacy, a risk/benefit analysis led to early study termination. TRIAL REGISTRATION NUMBER: NCT03666988.

BACKGROUND: Hypereosinophilic syndrome (HES) is a group of rare hematologic disorders leading to eosinophil-driven tissue damage and dysfunction. Better understanding of HES variants may facilitate improved patient management. OBJECTIVE: To describe disease characteristics, treatment, and outcomes of patients with idiopathic (I-HES), myeloproliferative (M-HES), lymphocytic (L-HES), and chronic eosinophilic leukemia, not otherwise specified (CEL-NOS) among HES case reports and aggregate data where available. METHODS: Relevant articles published between January 1, 2000, and March 20, 2020, were retrieved via PubMed; those reporting secondary, associated/reactive, overlap/single-organ, or familial HES were excluded. RESULTS: Of 188 articles included, 171 contained data on 347 separate HES cases (152 I-HES, 121 M-HES, 62 L-HES, 12 CEL-NOS). Based on individual data, mean age at diagnosis was 43 to 48 years for patients with all HES variants. Males accounted for 90% to 91% of M-HES/CEL-NOS and 55% to 65% of I-HES/L-HES cases. Cardiac symptoms were frequently observed for all HES variants (13%-22% of patients). Respiratory symptoms (I-HES), splenomegaly (M-HES and CEL-NOS), and skin conditions (L-HES) were also frequently observed. Bone marrow, heart, lung, spleen, liver, skin, and lymph nodes were commonly involved. Most patients with I-HES, L-HES, and CEL-NOS received corticosteroids (65%-85%), whereas most with M-HES received imatinib (81%); those with CEL-NOS also received interferon alpha (42%). CONCLUSIONS: Collective analysis of HES case reports supports and extends current understanding of HES variants, highlighting differences in signs and symptoms, organ involvement, and treatment approaches. Improved characterization of HES variants may facilitate the development of novel treatments.

BACKGROUND: A new trivalent inactivated split-virus influenza vaccine (TIV) was recently introduced in the United States. We assessed the efficacy of TIV against culture-confirmed influenza A and/or B. METHODS: In this double-blind trial conducted from September 2006 to May 2007 in the Czech Republic and Finland, participants aged 18-64 years were randomized to receive 1 dose of TIV (n = 5103) or placebo (n = 2549). Influenza-like illnesses (ILI) (defined as at least 1 systemic symptom [fever {oral temperature, > or = 37.8 degrees C} and/or myalgia] and at least 1 respiratory symptom [cough and/or sore throat]) were identified by both active (biweekly phone contact) and passive surveillance. Nasal and throat swab specimens were collected for viral culture. RESULTS: The attack rate for culture-confirmed ILI was 3.2% in the placebo group, with most strains identified as influenza A (all except 1 were H3N2) matching the vaccine strain. There were 6 cases of influenza B, all of which were of a different lineage (Yamagata) than the vaccine strain. Vaccine efficacy against culture-confirmed influenza A and/or B due to strains antigenically matched to the vaccine was 66.9% (95% confidence interval [CI], 51.9%-77.4%; P < .001) and to any strain was 61.6% (95% CI, 46.0%-72.8%; P < .001). CONCLUSION: TIV is efficacious against culture-confirmed influenza in healthy adults. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00363870.

Safe and reliable autonomous navigation in unstructured environments remains a challenge for field robots. In particular, operating on vegetated terrain is problematic, because simple purely geometric traversability analysis methods typically classify dense foliage as nontraversable. As traversing through vegetated terrain is often possible and even preferable in some cases (e.g., to avoid executing longer paths), more complex multimodal traversability analysis methods are necessary. In this article, we propose a three‐dimensional (3D) traversability mapping algorithm for outdoor environments, able to classify sparsely vegetated areas as traversable, without compromising accuracy on other terrain types. The proposed normal distributions transform traversability mapping (NDT‐TM) representation exploits 3D LIDAR sensor data to incrementally expand normal distributions transform occupancy (NDT‐OM) maps. In addition to geometrical information, we propose to augment the NDT‐OM representation with statistical data of the permeability and reflectivity of each cell. Using these additional features, we train a support‐vector machine classifier to discriminate between traversable and nondrivable areas of the NDT‐TM maps. We evaluate classifier performance on a set of challenging outdoor environments and note improvements over previous purely geometrical traversability analysis approaches.

Narcolepsy type 1 (NT1) is caused by a loss of hypocretin/orexin transmission. Risk factors include pandemic 2009 H1N1 influenza A infection and immunization with Pandemrix®. Here, we dissect disease mechanisms and interactions with environmental triggers in a multi-ethnic sample of 6,073 cases and 84,856 controls. We fine-mapped GWAS signals within HLA (DQ0602, DQB1*03:01 and DPB1*04:02) and discovered seven novel associations (CD207, NAB1, IKZF4-ERBB3, CTSC, DENND1B, SIRPG, PRF1). Significant signals at TRA and DQB1*06:02 loci were found in 245 vaccination-related cases, who also shared polygenic risk. T cell receptor associations in NT1 modulated TRAJ*24, TRAJ*28 and TRBV*4-2 chain-usage. Partitioned heritability and immune cell enrichment analyses found genetic signals to be driven by dendritic and helper T cells. Lastly comorbidity analysis using data from FinnGen, suggests shared effects between NT1 and other autoimmune diseases.

BackgroundVaccine effectiveness of pneumococcal conjugate vaccines against culture-confirmed invasive pneumococcal disease has been well documented.In the Finnish Invasive Pneumococcal disease (FinIP) trial, we reported vaccine effectiveness and absolute rate reduction against laboratory-confirmed invasive pneumococcal disease (confirmation by culture or antigen or DNA detection irrespective of serotype).Here, we assessed vaccine effectiveness of PHiD-CV10 against clinically suspected invasive pneumococcal disease in children by use of diagnoses coded in hospital discharge registers. MethodsFor this phase 3/4 cluster-randomised, double-blind trial, undertaken between Feb 18, 2009, and Dec 31, 2011, in municipal health-care centres and the Tampere University Vaccine Research Centre (Finland), we randomly assigned (2:2:1:1) 78 clusters into PHiD-CV10 three plus one, PHiD-CV10 two plus one, control three plus one, control two plus one groups (26:26:13:13 clusters) to give PHiD-CV10 in either three plus one or two plus one schedule (if enrolled before 7 months of age; infant schedules), two plus one (if enrolled between 7 and 11 months; catch-up schedules), and two doses at least 6 months apart (if enrolled between 12 and 18 months; catch-up schedules).Children were eligible if they had not received and were not anticipated to receive any of the study vaccines and had no general contraindications to vaccinations.We collected all inpatient and outpatient discharge notifications from the national hospital discharge register with International Classification of Diseases (ICD) 10 diagnoses compatible with invasive pneumococcal disease or unspecified sepsis, and verified data with patient files.We excluded invasive pneumococcal disease cases confirmed by positive culture or DNA/RNA detection from normally sterile body fluid.The primary objective was to estimate vaccine effectiveness against all register-based non-laboratory-confirmed invasive pneumococcal disease or unspecified sepsis and patient-file verified non-laboratory-confirmed invasive pneumococcal disease in infants younger than 7 www.thelancet.com/respiratoryPublished online August 8,

OBJECTIVES: This cross-sectional study estimates the resource use and costs among prevalent colorectal cancer (CRC) patients in different states of the disease. METHODS: Altogether 508 Finnish CRC patients (aged 26-96; colon cancer 56%; female 47%) answered a questionnaire enquiring about informal care, work capacity, and demographic factors. Furthermore, data on direct medical resource use and productivity costs were obtained from registries. Patients were divided into five mutually exclusive groups based on the disease state and the time from diagnosis: primary treatments (the first six months after the diagnosis), rehabilitation, remission, metastatic disease, and palliative care. The costs were calculated for a six-month period. Multivariate modeling was performed to find the cost drivers. RESULTS: The costs were highest during the primary treatment state and the advanced disease states. The total costs for the cross-sectional six-month period were €22 200 in the primary treatment state, €2106 in the rehabilitation state, €2812 in the remission state, €20 540 in the metastatic state, and €21 146 in the palliative state. Most of the costs were direct medical costs. The informal care cost was highest per patient in the palliative care state, amounting to 33% of the total costs. The productivity costs varied between disease states, constituting 19-40% of the total costs, and were highest in the primary treatment state. CONCLUSIONS: The first six months after the diagnosis of CRC are resource intensive, but compared with the metastatic disease state, which lasts on average for 2-3 years, the costs are rather modest. Informal care constitutes a remarkable share of the total costs, especially in the palliative state. These results form a basis for the evaluation of the cost effectiveness of new treatments when allocating resources in CRC treatment.

BACKGROUND: Almost 700 cases of human infection with avian influenza A/H7N9 have been reported since 2013. Pandemic preparedness strategies include H7N9 vaccine development. METHODS: ), one nonadjuvanted vaccine, or placebo. The coprimary immunogenicity objective determined whether adjuvanted vaccines elicited an immune response against the vaccine-homologous virus, 21 days after the second vaccine dose per US and European licensure criteria in the per-protocol cohort (n = 389). RESULTS: All adjuvanted vaccines met regulatory acceptance criteria. In groups receiving adjuvanted formulations, seroconversion rates were ≥85.7%, seroprotection rates ≥91.1%, and geometric mean titers ≥92.9% versus 23.2%, 28.6%, and 17.2 for the nonadjuvanted vaccine. The AS03 adjuvant enhanced immune response at antigen-sparing doses. Injection site pain occurred more frequently with adjuvanted vaccines (in ≤98.3% of vaccinees) than with the nonadjuvanted vaccine (40.7%) or placebo (20.0%). None of the 20 serious adverse events reported were related to vaccination. CONCLUSIONS: Two doses of AS03-adjuvanted H7N9 vaccine were well tolerated and induced a robust antibody response at antigen-sparing doses in healthy adults. CLINICAL TRIALS REGISTRATION: NCT01999842.
