RESUMO

OBJECTIVE: To evaluate the efficacy and safety of faricimab compared with other anti-vascular endothelial growth factor (anti-VEGF) agents in treating neovascular age-related macular degeneration (nAMD) patients. METHODS AND ANALYSIS: A systematic review (SR) was conducted up to January 2023. Network meta-analyses (NMA) were performed, including sensitivity and subgroup analyses for naïve population. Outcomes included changes in visual acuity (Early Treatment of Diabetic Retinopathy Study [ETDRS] letters), anatomical changes, frequency of injections and adverse events. The Cochrane Collaboration guidelines and the Confidence in Network Meta-Analysis framework were used for the SR and the certainty of evidence, respectively. RESULTS: From 4128 identified records through electronic databases and complementary searches, 63 randomised controlled trials (RCTs) met the eligibility criteria, with 42 included in the NMA. Faricimab showed a significant reduction in the number of annual injections compared with most fixed and flexible anti-VEGF treatment regimens, while showing no statistically significant differences in visual acuity through ETDRS letter gain, demonstrating a comparable efficacy. Retinal thickness results showed comparable efficacy to other anti-VEGF agents, and inferior only to brolucizumab. Results also showed that more patients treated with faricimab were free from post-treatment retinal fluid compared with aflibercept every 8 weeks, and both ranibizumab and bevacizumab, in the fixed and pro re nata (PRN) assessed schedules. Faricimab showed a comparable safety profile regarding the risk of ocular adverse events and serious ocular adverse events (SOAE), except for the comparison with brolucizumab quarterly, in which faricimab showed a significant reduction for SOAE risk. CONCLUSION: Faricimab showed a comparable clinical benefit in efficacy and safety outcomes, with a reduction in annual injections compared with fixed and flexible anti-VEGF drug regimens, representing a valuable treatment option for nAMD patients.

RESUMO

BACKGROUND: X-linked myotubular myopathy (XLMTM) is a rare, life-threatening congenital disease, which is not well-defined. To our knowledge, no studies characterizing the XLMTM disease burden have been conducted in Brazil. We identified and described patients with suspected XLMTM using administrative claims data from the Brazilian public healthcare system. METHODS: Data from 2015 to 2019 were extracted from the DATASUS database. As no XLMTM-specific ICD-10 code was available, a stepwise algorithm was applied to identify patients with suspected XLMTM by selecting male patients with a congenital myopathies code (G71.2), aged < 18 years at index date (first claim of G71.2), with an associated diagnostic procedure (muscle biopsy/genetic test) and without spinal muscular atrophy or Duchenne muscular dystrophy. We attempted to identify patients with suspected severe XLMTM based on use of both respiratory and feeding support, which are nearly universal in the care of XLMTM patients. Analyses were performed for the overall cohort and stratified by age at index date < 5 years old and ≥ 5 years old. RESULTS: Of 173 patients with suspected XLMTM identified, 39% were < 5 years old at index date. Nearly all (N = 166) patients (96%) were diagnosed by muscle biopsy (91% of patients < 5 years old and 99% of patients ≥ 5 years old), six (3.5%) were diagnosed by clinical evaluation (8% of patients < 5 years old and 1% of patients ≥ 5 years old), and one was diagnosed by a genetic test. Most patients lived in Brasilia (n = 55), São Paulo (n = 33) and Minas Gerais (n = 27). More than 85% of patients < 5 years old and approximately 75% of patients ≥ 5 years old had physiotherapy at the index date. In both age groups, nearly 50% of patients required hospitalization at some point and 25% required mobility support. Respiratory and feeding support were required for 3% and 12% of patients, respectively, suggesting that between 5 and 21 patients may have had severe XLMTM. CONCLUSION: In this real-world study, genetic testing for XLMTM appears to be underutilized in Brazil and may contribute to underdiagnosis of the disease. Access to diagnosis and care is limited outside of specific regions with specialized clinics and hospitals. Substantial use of healthcare resources included hospitalization, physiotherapy, mobility support, and, to a lesser extent, feeding support and respiratory support.

RESUMO

INTRODUCTION: Cardiovascular diseases account for over 80% of global deaths. Risk factors and social determinants influence mortality in patients post acute myocardial infarction (AMI). OBJECTIVE: To evaluate factors associated with post-AMI mortality during the one-year follow-up. MATERIALS AND METHODS: The study is a prospective cohort study of adults aged 18 years and older with type 1 AMI conducted between October 2021 and January 2024. Intrahospital and outpatient information was collected. Statistical analyses included the Kaplan-Meier survival curve and Cox regression analysis. Proportional hazards and model predictive capacity were evaluated. RESULTS: A total of 1873 patients were included, with a 9.4% mortality rate in the first year. At one year, the estimated survival probability was 88.61% (95% CI: 86.82-90.18). Cox analysis identified several factors associated with mortality, highlighting age (HR = 1.04, 95% CI: 1.02-1.06, p = 0.001), diabetes (HR = 1.77, 95% CI: 1.09-2.87, p = 0.020), renal insufficiency (HR = 2.25, 95% CI: 1.32-3.84, p = 0.003), and type of intervention. The model evaluation showed strong predictive capacity. CONCLUSIONS: It is essential to emphasize the importance of comprehensive management in AMI patients with risk factors such as diabetes and chronic kidney disease, as they are significant predictors of mortality during the first year post infarction.

RESUMO

OBJECTIVE: To assess the economic burden of neuromyelitis optica spectrum disorder (NMOSD) in the Colombian context. METHODS: Analyses were conducted from a societal perspective using the prevalence-based approach. Costs were expressed in 2022 US dollars (1 USD = $3,914.46 COP). Direct medical costs were assessed from a bottom-up approach. Indirect costs included loss of productivity of the patient and their caregivers. The economic burden of NMOSD in Colombia was estimated as the sum of direct and indirect costs. RESULTS: The direct cost of treating a patient with NMOSD was USD$ 8,149.74 per year. When projecting costs nationwide, NMOSD would cost USD$ 7.2 million per year. Of these costs, 53.5% would be attributed to relapses and 34.4% to pharmacological therapy. Indirect costs potentially attributed to NMOSD in Colombia were estimated at USD$ 1.5 million per year per cohort. Of these, 78% are attributable to loss of patient productivity, mainly due to reduced access to the labor market and premature mortality. CONCLUSIONS: The NMOSD has a representative economic burden at the patient level, with direct costs, particularly related to relapses and medicines, being the main component of total costs. These findings are useful evidence that requires attention from public policymakers in Colombia.

RESUMO

Home confinement during the onset of the SARS-CoV-2 pandemic decreased sunlight exposure, the main source of vitamin D in the body. OBJECTIVE: To evaluate the impact of SARS-CoV-2 confinement on 25-hydroxyvitamin D (25-OH-VD) levels in a pediatric population. PATIENTS AND METHODS: Observational study in a Spanish pediatric population between June and October 2020. 25-OH- VD levels were measured by electrochemiluminescence and several related variables were collected (anthropometry, sex, skin phototype, date, calcium level, inorganic phosphorus, parathormone, and alkaline phosphatase). The child's companion answered a survey that included the following aspects: access to open air in the house where the confinement took place, hours of sunlight per day received by the child after the end of the confinement, regular use of sunscreen with outdoor exposure, skin phototype of the child, type of milk the child usually drinks, 25-OH-VD supplementation intake, and if so, dosage and adherence to treatment. RESULTS: 123 children participated, mean age 8.15 years (95%CI 7.52-8.79), and 56.1% were female. The median 25-OH-VD was 27.70 ng/ml (RIC 22.7533.60), and 14% presented 25-OH-VD insufficiency (< 20 ng/ml). 25-OH-VD levels presented an ascending correlation slope as the date moved away from the end of confinement (Rho 0.467; p < 0.001), being related to sunshine hours (Rho 0.368; p < 0.001). 25-OH-VD levels were higher in patients with photoprotection (median 29.9 vs 23.5 ng/ml, p = 0.005), with differences according to skin phototype (p = 0.032), but were not related to age, weight z-score, height z-score, body mass index z-score, or the presence of a balcony or garden at home. CONCLUSION: The rate of 25-OH-VD insufficiency at the end of confinement was not higher than in previous studies. 25-OH-VD levels increased progressively in relation to the hours of sunlight exposure and to the summer months. Interestingly, 25-OH-VD levels were higher in children using phot.

RESUMO

Pollution from plastic waste thrown into the ocean affects all levels of the food chain. Marine species of birds are affected by plastic particles of different sizes, especially the mesoplastics (1 to 10 mm) found in their digestive tract, which mainly cause obstructions. In the case of microplastics (1.000 µm to 1 mm), their presence in the digestive tract of these species has been widely reported. We studied fecal samples of the Dominican gull (Larus dominicanus) (n = 14), Magellanic penguins (Spheniscus magellanicus) (n = 8), and Humboldt penguin (Spheniscus humboldti) (n = 1) obtained from the Wildlife Rehabilitation Center of the Biobío region, Chile. Microfibers of various colors were present in the feces of Dominican gulls and Magellanic penguins, corresponding mainly in composition to polypropylene (PP) (83%) and rayon (77%). These results demonstrate that microplastic particles occur in the coastal environments of central Chile and suggest that they are probably circulating in the food chain.

RESUMO

Aim: To compare the efficacy and safety of alectinib with other ALK inhibitors in treating patients with metastatic or locally advanced ALK-positive NSCLC. Methods: A systematic literature review was conducted up to November 2021. Network meta-analyses were performed using the frequentist method (random effects). GRADE evidence profile was conducted. Results: 13 RCTs were selected. For overall survival, alectinib was found to reduce the risk of death compared with crizotinib. In progression-free survival, alectinib reduced the risk of death or progression compared with crizotinib and ceritinib. Subgroup analysis by brain metastasis at baseline showed the superiority of alectinib over crizotinib and a similar effect compared with second-and third-generation inhibitors. Alectinib showed a good safety profile compared with the other ALK inhibitors.

This article reports the results of a systematic literature review with network meta-analysis (NMA) that aimed to compare the efficacy and safety of alectinib with other ALK inhibitors in treating patients with metastatic or locally advanced ALK-positive NSCLC. The results show that alectinib reduces the risk of death and the risk of progression compared with crizotinib. For progression-free survival, further significant reductions were observed when compared with ceritinib. For the other ALK inhibitors, no statistically significant differences were found. Subgroup analysis according to the presence of CNS metastases at baseline were consistent in showing the superiority of alectinib over crizotinib and the absence of statistically significant differences compared with second-and third-generation inhibitors. Alectinib showed a good safety profile compared with the other ALK inhibitors, reducing the frequency of adverse events (AEs) compared with ceritinib, and with no statistically significant differences compared with lorlatinib, brigatinib, ensartinib and crizotinib for the frequency of serious AEs or discontinuation of treatment due to AEs. The results of this study suggest clinically relevant insights in decision-making based on patient survival and progression-free survival. Furthermore, considering the importance of reducing the risk of intracranial progression and the need for available therapies for patients who will inevitably progress, alectinib could be considered as a first-line treatment for patients with ALK-positive NSCLC.

RESUMO

OBJECTIVE: This article estimates the disease burden of 5q-SMA in Colombia by using the disability-adjusted life years (DALYs) metric. METHODS: Epidemiological data were obtained from local databases and medical literature and were adjusted in the DisMod II tool. DALYs were obtained by adding years of life lost due to premature death (YLL) and years lived with disability (YLD). RESULTS: The modeled prevalence of 5q-SMA in Colombia was 0.74 per 100,000 population. The fatality rate for all types was 14.1%. The disease burden of 5q-SMA was estimated at 4,421 DALYs (8.6 DALYs/100,000), corresponding to 4,214 (95.3%) YLLs and 207 (4.7%) YLDs. Most of the DALYs were accounted in the 2-17 age group. Of the total burden, 78% correspond to SMA type 1, 18% to type 2, and 4% to type 3. CONCLUSIONS: Although 5q-SMA is a rare disease, it is linked to a significant disease burden due to premature mortality and severe sequelae. The estimates shown in this article are important inputs to inform public policy decisions on how to ensure adequate health service provision for patients with 5q-SMA.

RESUMO

OBJECTIVES: To conduct cost-utility and budget impact analysis of providing Continuous Positive Airway Pressure (CPAP) therapy versus no treatment for moderate to severe obstructive sleep apnea (OSA) in Colombia from a third-party payer perspective. METHODS: We used a Markov model to assess the cost-utility and budget impact analysis of CPAP in patients over 40 years old with moderate to severe OSA. Data on effectiveness and utility values were obtained from published literature. A discount rate of 5% was applied for outcomes and costs. ICER was calculated and compared against the threshold estimated for Colombia, which is 86% of the GDP per capita. RESULTS: Over a lifetime horizon, the base case analysis showed the incremental cost per quality-adjusted life-years (QALYs) gained with CPAP therapy was COP$3,503,804 (USD$1,011 in 2020 prices). The budget impact analysis showed that the adoption of CPAP therapy in the target population would lead to a cumulative net budget impact of COP$411,722 million (USD$118,784,412 in, 2020 prices) over five years of time horizon. CONCLUSIONS: CPAP was cost-effective compared to no-treatment in OSA. According to the budget impact analysis, adopting this technology would require a budget allocation that is partially offset by reduced number of strokes and traffic accident events.
