RESUMO
Background: Knowledge of prevalence and epidemiology of cystic fibrosis (CF) and healthcare resource use among Finnish people with CF is incomplete. Methods: We conducted a population-based matched cohort study using retrospective real-world data from linked Finnish national registries. Electronic healthcare data and drug purchases of 102 people with CF were analyzed between January 2015 and December 2019 (follow-up). A 5-fold control population was matched by sex, age, and place of residence. Comorbidities and medication use that occurred at any time during follow-up were assessed; annual rates of hospital service use were adjusted for follow-up. Results: The prevalence of CF in Finland was 1.85 per 100,000. Median age at diagnosis was 1 year, with 60 % diagnosed at age <2 years and 80 % at age <10 years. Median age at death in people with CF was 31.4 years (n < 5); no controls died. The most common comorbidities included chronic sinusitis (39.2 %), pneumonia (38.2 %), diabetes (20.6 %), and nasal polyps (18.6 %). The most purchased medications were antibiotics (99.0 %) and pancreatic enzymes (84.3 %). The annualized rate of hospital visits was higher in people with CF vs controls (outpatient: mean [SD], 17.4 [14.5] vs 0.9 [3.3]; median, 13.6 vs 0.4, respectively; inpatient: mean [SD], 1.0 [1.66] vs 0.03 [0.14]; median, 0.34 vs 0, respectively). Conclusions: The prevalence of CF in Finland is remarkably low, likely reflecting unique population characteristics and, in part, delayed diagnosis. Antibiotic use is frequent among Finnish people with CF. Inpatient hospital visits are >30 times higher in people with CF than matched controls.
RESUMO
BACKGROUND/AIM: Per literature, patients with epidermal growth factor receptor (EGFR) exon-20 insertions respond poorly to tyrosine kinase inhibitors (TKIs). This study analyzed real-world data to examine the prognostic and predictive value of these mutations. PATIENTS AND METHODS: We conducted a retrospective cohort study using Czech TULUNG Registry data, with data on multiple mutation types, collected in 2011-2020. RESULTS: We analyzed 554 (95.85%) patients with EGFR exon-19 deletions or exon-21 L858R substitutions and 24 (4.15%) patients with exon-20 insertions who received first-line high-value therapies. We summarized clinical characteristics and outcomes in all patients and by cohort. The risk of progression was statistically significantly higher (86%) in the exon-20 insertion cohort compared to the cohort with other mutations. Although not statistically significant, the risk of death was 44% higher in patients with exon-20 insertions. CONCLUSION: Advanced NSCLC patients with rare EGFR exon-20 insertions have a high risk of progression.

AIM: To investigate the cost-effectiveness of palivizumab vs. no prophylaxis for respiratory syncytial virus (RSV) infection in preterm infants in Sweden. METHODS: A probabilistic Markov model was populated using a nationwide register linkage and data from the literature. Cost-effectiveness was investigated from a societal perspective over a lifetime for infants born at <29 weeks of gestation. Palivizumab was modelled using assumptions for its direct effect on RSV hospitalization risk and an indirect effect (via decreased RSV hospitalization) on subsequent asthma and mortality during the epidemic. Costs and effects were discounted by 3%. RESULTS: In the base case, prophylaxis resulted in an additional 0.102 quality-adjusted life-year (QALY) at a cost of 20,000 SEK relative to no prophylaxis (incremental cost-effectiveness ratio [ICER] 195,000 SEK/QALY). The probability of prophylaxis being cost-effective was 99% at a willingness-to-pay of 500,000 SEK/QALY. Assumptions about a causal association between RSV infection and subsequent asthma had a moderate impact, while exclusion of the indirect prophylaxis effect on mortality increased the ICER to 492,000 SEK/QALY. When excluding both of these, prophylaxis was not cost-effective. CONCLUSION: Based on a willingness-to-pay of 500,000 SEK/QALY, palivizumab was found to be cost-effective compared with no prophylaxis for infants born at <29 weeks if severe RSV infection was assumed to increase subsequent asthma or mortality risk.
