In October 2014, the anti-fibrotic medications pirfenidone and nintedanib became the first medications approved by the Food and Drug Administration for use in patients with idiopathic pulmonary fibrosis. Since approval, there has been no non-registry analysis of the real-world adoption of these medications in every day clinical practice.

To evaluate the adoption, persistence, and out-of-pocket costs of pirfenidone and nintedanib since their approval in the US in 2014 Methods A retrospective cohort analysis was performed by identifying privately insured and Medicare Advantage beneficiaries with idiopathic pulmonary fibrosis. We then split the patients into three cohorts those who were untreated and those that filled a prescription for either pirfenidone or nintedanib between October 1, 2014 and July 31, 2019. The primary outcome was adoption of the medications. Secondary outcomes included medication persistence and prescription drug costs.

A total of 10,996 patients with IPF were identified in the datasehas been low since approval and may be associated with the high out-of-pocket cost.Rationale Posttranscriptional modifications are implicated in vascular remodeling of pulmonary hypertension (PH). m6A (N6-methyladenosine) is an abundant RNA modification that is involved in various biological processes. Whether m6A RNA modification and m6A effector proteins play a role in pulmonary vascular remodeling and PH has not been demonstrated.Objectives To determine whether m6A modification and m6A effectors contribute to the pathogenesis of PH.Methods m6A modification and YTHDF1 expression were measured in human and experimental PH samples. RNA immunoprecipitation analysis and m6A sequencing were employed to screen m6A-marked transcripts. MEK inhibitor review Genetic approaches were employed to assess the respective roles of YTHDF1 and MAGED1 in PH. Primary cell isolation and cultivation were used for function analysis of pulmonary artery smooth muscle cells (PASMCs).Measurements and Main Results Elevated m6A levels and increased YTHDF1 protein expression were found in human and rodent PH samples as well as in hypoxic PASMCs. The deletion of YTHDF1 ameliorated PASMC proliferation, phenotype switch, and PH development both in vivo and in vitro. m6A RNA immunoprecipitation analysis identified MAGED1 as an m6A-regulated gene in PH, and genetic ablation of MAGED1 improved vascular remodeling and hemodynamic parameters in SU5416/hypoxia mice. YTHDF1 recognized and promoted translation of MAGED1 in an m6A-dependent manner that was absent in METTL3-deficient PASMCs. In addition, MAGED1 silencing inhibited hypoxia-induced proliferation of PASMCs through downregulating PCNA.Conclusions YTHDF1 promotes PASMC proliferation and PH by enhancing MAGED1 translation. This study identifies the m6A RNA modification as a novel mediator of pathological changes in PASMCs and PH.Purpose This study sought to evaluate the effects of common hearing aid microphone technologies on speech recognition and listening effort, and to evaluate potential predictive factors related to microphone benefits for school-age children with hearing loss in a realistic listening situation. Method Children (n = 17, ages 10-17 years) with bilateral, sensorineural hearing loss were fitted with hearing aids set to include three programs omnidirectional, adaptive directional, and omnidirectional + remote microphone. Children completed a dual-task paradigm in a moderately reverberant room. The primary task included monosyllabic word recognition, with target speech presented at 60 dB A from 0° (front) or 180° (back) azimuth. The secondary task was a "go/no-go," visual shape-recognition task. Multitalker babble noise created a +5 dB SNR. Children were evaluated in two speaker conditions (front, back) using all three hearing aid programs. The remote microphone transmitter remained at the front speaker throughout testing. Speech recognition performance was calculated from the primary task while listening effort was measured as response time during the secondary task. Results Speech presented from the back significantly increased listening effort and caused a reduction in speech perception when directional and remote microphones were used. Considerable variability was found in pattern of benefit across microphones and source location. Clinical measures did not predict benefit patterns with directional or remote microphones; however, child age and performance with omnidirectional microphones did. Conclusions When compared to a traditional omnidirectional setting, the directional and remote microphone configurations evaluated in this study have the potential to provide benefit for some children and increase difficulty for others when used in dynamic environments. A child's performance with omnidirectional hearing aids could be used to better inform clinical recommendations for these technologies.Purpose The association between voice alterations, health-related quality of life (HRQL), and chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), has previously been reported. The aim of this study was to test the hypothesis that HRQL and dysphonia-associated handicap of patients diagnosed with asthma or COPD are worse than healthy controls. Method A case-control study in which participants were recruited by a consecutive sampling method from a single institution was conducted. Three groups were created (a) asthma (51 patients), (b) COPD (52 patients), and (c) 50 healthy controls. Self-reported handicap associated with dysphonia was assessed using the 30-item Voice Handicap Index (VHI-30); meanwhile, HRQL was tested via the European Quality of Life (EQ) Questionnaire and the EQ-visual analog scale. Also, aerodynamic assessment applied to phonation was assessed, and maximum phonation time and s/e index were registered. Results VHI scores were higher for asthma and COPD (7.19 ± 8.31 and 11.80 ± 15.18, respectively) than in the control group (3.72 ± 6.78). The EQ index was lower in asthma and COPD patients than in controls. The EQ-visual analog scale showed lower scores in asthma and COPD than in the controls. Conclusions HRQL was worse in COPD patients than in asthma patients. Even though the patient groups showed worse VHI and HRQL scores than the healthy controls, the scores fell within the normal variation range. No significant variations in the maximum phonation time index between groups were noted.
