Background: Long non-coding RNAs (lncRNAs) are key regulators of cellular processes that underpin cancer development and progression. DRAIC is a migration inhibitor that has been linked with lung adenocarcinoma progression; however, its mechanisms remain to be studied. Methods: several bioinformatics tools were used to explore the role of DRAIC in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC). Results: Our bioinformatics analysis illustrates that patients with low expression of DRAIC have poor overall survival outcomes. In addition, the mRNA of SH3 domain-binding kinase 1 (SBK1) was downregulated in this cohort of patients. Mechanistic analysis showed that SBK1 is under the DRAIC competing endogenous RNAs network, potentially through sponging of miRNA-92a. Conclusion: Consistent dysregulation of the DRAIC-SBK1 axis was linked to poor survival outcome in both LUAD and LUSC, suggesting a tumour inhibitor role and providing potential for new diagnostics and therapeutic approaches....
Background: Respiratory infections were found to be connected with the incidence of acute coronary syndrome (ACS). The proposed pathway of this connection includes inflammation, oxidative stress, pro-coagulation, and atherosclerotic plaque destabilization. This can cause rapture and thrombus formation, leading to ACS. Our study aimed to assess the risk factors for coronary artery thrombosis as a manifestation of ACS and for lower respiratory tract infections (LRTIs) in patients with ACS. Methods: The study included 876 patients with ACS from January 2014 to December 2018. Both the clinical data and air pollution data were analyzed. Statistical tests used for analysis included Student’s t-test, the Mann–Whitney U-test, the Chi-squared test, and the odds ratio Altman calculation. Results: LRTIs were found in 9.13% patients with ACS. The patients with LRTI had a higher risk of coronary artery thrombosis (OR: 2.4903; CI: 1.3483 to 4.5996). Moreover, they had increased values of inflammatory markers, were older, had a lower BMI, and a higher rate of atrial fibrillation. The average atmospheric aerosols with a maximum diameter of 2.5 μm (PM2.5 concentration) from three consecutive days before hospitalization for ACS were higher in patients with LRTI. Conclusions: The occurrence of coronary artery thrombosis was higher among the patients with LRTI during ACS. PM2.5 exposition was higher in the three consecutive days before hospitalization in patients with LRTI during ACS....
Patients with rheumatoid arthritis (RA) are at increased risk of developing interstitial lung disease compared to the general population, a complication that is associated with significant morbidity and high mortality. Given its frequency and severity, ILD should always be considered during both the initial assessment and follow-up of RA patients. However, there is currently no consensus on which RA patients should be screened for ILD. In recent years, several scientific societies have developed specific screening proposals. According to the recommendations of the Spanish, American, and Austrian rheumatology societies, it is not necessary to screen all individuals with RA, and it should be tailored to each patient based on clinical risk factors. In contrast, the Portuguese Societies of Rheumatology and Pulmonology advocate for systematic screening of all RA patients. Risk factors for the development of ILD in RA patients are well identified, and several screening tools for RA-ILD based on these risk factors have been developed. However, all of these tools still require further validation. To address this issue, the ANCHOR-RA study, a multinational cross-sectional initiative, has been launched to develop a multivariable model for predicting RA-ILD, which could provide valuable guidance for screening practices in clinical settings. In addition to certain biochemical and genetic predictive markers, lung ultrasound appears to be a useful screening tool. When combined with clinical evaluation and risk factor assessment, it can help identify which patients require a thoracic HRCT evaluation, which remains the gold standard for confirming an ILD diagnosis....
A 66-year-old man, a 40-year smoker, was diagnosed with rheumatoid arthritis in 2018. He was treated for one year with methotrexate, and, later in 2020, he was diagnosed with interstitial pulmonary fibrosis. In 2022, treatment with nintedanib was initiated, with clinical improvement being indicated but without showing a functional or imaging benefit. The evolution of the disease was rapidly progressive and unfavorable, with death occurring due to pulmonary thromboembolism. Following the autopsy, triple lesions of the RA at the lung level were confirmed: interstitial, of the NSIP type with a fibrosing character at the level of the lower airways of the bilateral bronchiectasis type, and vascular damage due to pulmonary thromboembolism secondary to chronic inflammation....
Nintedanib, an intracellular inhibitor that targets multiple tyrosine kinase, is an important drug for the treatment of pulmonary fibrosis. Until now, no studies have been published reporting the nintedanib tolerability or its efficacy in patients with chronic pulmonary lung disease and chronic kidney disease comorbidity. The safety, efficacy and pharmacokinetics of nintedanib have not been studied in patients with severe renal impairment (creatinine clearance < 30 mL/min) and for this reason it is contraindicated in these patients. We describe a case of use of nintedanib in a patient affected by idiopathic pulmonary fibrosis (IPF) who started, from 2022, nintedanib 150 mg twice a day with careful monitoring of liver and kidney function. Due to the onset of stage 3/4 chronic kidney disease associated with proteinuria, nintedanib was suspended for two months, and the patient received Prednisone at a dose of 12.5 mg/day. During the two months of suspension, the renal function did not improve, unlike the respiratory status worsened. In the past a renal biopsy was performed which showed no correlation with nintedanib use. Nintedanib therapy started again following the decline in lung function and desaturation below 90% in the 6-min walking test (6MWT). Patient showed a good tolerability of nintedanib with sporadic episode of diarrhea and an improvement of pulmonary function leading to a stable state of chronic pulmonary fibrosis disease. For this reason, in mutual agreement with the patient, we decided to maintain nintedanib therapy even when the patient required hemodialysis. No toxic effects appeared. This case report revealed the safety of nintedinab in patient with concomitant kidney failure, but more studies are necessary....
