6% of cases), calcification (55.6% of cases), and demonstrated elastic fiber fragmentation and degeneration (all cases).

As in few previous reports, many patients with MFS develop bilateral or postoperative recurrent pneumothoraces. In many patients, characteristic changes in the pulmonary bullae, possibly caused by degenerated elastic fibers, were observed.

Eosinophilic chronic obstructive pulmonary disease (COPD) patients have eosinophilic airway inflammation. alpha-Naphthoflavone inhibitor No prospective study has reported blood eosinophil counts in an endemic area for parasitic infection. The primary objective was to compare exacerbation rates. The secondary objectives were patient-reported outcomes between eosinophilic and non-eosinophilic COPD.

A prospective study was conducted in COPD patients for 52 weeks. COPD was diagnosed according to GOLD criteria. Blood eosinophil counts were recorded at study entry. Exacerbations were recorded during the entire study period whereas COPD Assessment Test (CAT) and spirometry were recorded at 12 months. The eosinophilic and non-eosinophilic groups were defined by blood eosinophil counts ≥300 and <300 cells/µL, respectively.

A total of 145 COPD patients were included. Fifty-eight (40%) and 87 (60%) patients were eosinophilic and non-eosinophilic COPD and the median [interquartile range (IQR)] eosinophil counts were 481 [378.5, 675] and 149 [101.2, 208] cells/µL, respectively. The median (IQR) annual exacerbation rates were 3 [2, 4] and 2 [2, 2.5] times/year in the eosinophilic and non-eosinophilic groups, respectively (P=0.024). The eosinophilic group had higher admissions (P=0.007) but lower mortality (P=0.041). The patient-reported outcomes were not statistically significantly different between the two groups. Eosinophil counts ≥300 cells/µL identified exacerbation in COPD patients with sensitivity and specificity of 0.71 and 0.64, respectively.

COPD patients with blood eosinophil counts ≥300 cells/µL had more exacerbations and admissions but lower mortality than the non-eosinophilic patients. Blood eosinophil count is an effective biomarker to predict exacerbation risk in endemic parasitic areas.

Fiberoptic bronchoscopy (FOB) with broncho-alveolar lavage (BAL) is frequently performed in patients with hematological malignancies and pulmonary opacities. While the safety of the procedure in this patient population has been shown, data about the diagnostic yield widely differ between studies. Furthermore, data comparing diagnostic yield and safety of flexible bronchoscopy to narrow sources of pulmonary infections in patients with and without underlying hematological malignancy are lacking.

We carried out a retrospective analysis of bronchoscopies done for the diagnostic work-up of pulmonary infections. Diagnostic yield and the occurrence of complications in patients with and without hematological disease were compared.

In total n=268 bronchoscopies were done in patients suffering from a hematological malignancy (HM) compared to n=408 bronchoscopies in patients without hematological malignancy (NHM). The overall diagnostic yield was similar and did not differ between the groups (HM 67.2%
NHM 64.7%; P=0.5622). However, when cultures positive for Candida were not considered as clinically relevant diagnostic yield was higher in the HM group (HM 62.7%
NHM 53.9%; P=0.0261) due to a higher detection rate of fungi and viruses (both P<0.001). Interestingly, the diagnostic yield for bacteria was not decreased by pre-treatment with antibiotics in either group (both P>0.05). There was no difference in the complication rate between the groups and most complications were considered as minor.

In summary, our data demonstrate similar diagnostic yield and safety of flexible bronchoscopy for diagnosing pulmonary infection in patients with and without underlying hematological malignancy.

To analyze the risk factors of chronic left ventricular dysfunction (LVD) after cardiac valve surgery.

A retrospective analysis of 860 patients who underwent heart valve surgery in our center from January 2017 to December 2018, including 650 males and 210 females, aged 58±5.8 years. Inclusion criteria (I) the patient was clinically diagnosed with heart valve disease and met the surgical indications for mitral valve replacement (MVR), mitral valve repair (MVP), aortic valve replacement (AVR) and double valve replacement (DVR); (II) if atrial fibrillation, coronary artery disease, and tricuspid regurgitation are combined before surgery, radiofrequency ablation, coronary bypass and tricuspid angioplasty were performed contemporarily. Exclusion criteria (I) preoperative LVEF <50%; (II) aortic dissection underwent Bentall and right heart valve replacement procedures; (III) cardiopulmonary resuscitation and death during perioperative period and 6 months after operation; (IV) postoperative CRRT, IABP, or ECMOtive NYHA III-IV, and preoperative combined coronary artery disease were the risks of postoperative chronic LVD.

The left ventricular diameter, preoperative coronary artery disease, NYHA III-IV, preoperative atrial fibrillation, and preoperative pulmonary hypertension are risk factors for chronic LVD after heart valve surgery.

Aortic dissection is one of the most detrimental cardiovascular diseases with a high risk of mortality and morbidity. This study aimed to examine the key genes and microRNAs associated with Stanford type A aortic dissection (AAD).

The expression data of AAD and healthy samples were downloaded from two microarray datasets in the Gene Expression Omnibus (GEO) database to identify highly preserved modules by weighted gene co-expression network analysis (WGCNA). Differentially expressed genes (DEGs) and differentially expressed miRNAs (DEmiRNAs) were selected and functionally annotated. The predicted interactions between the DEGs and DEmiRNAs were further illustrated.

In two highly preserved modules, 459 DEGs were identified. These DEGs were functionally enriched in the HIF1, Notch, and PI3K/Akt pathways. Furthermore, 6 DEmiRNAs that were enriched in the regulation of vasculature development and HIF1 pathway, were predicted to target 23 DEGs.

Our study presented several promising modulators, both DEGs and DEmiRNAs, as well as possible pathological pathways for AAD, which narrows the scope for further fundamental research.
