Pulmonary hypertension (PH) is a mortal disease featured with pulmonary vascular constriction and remodeling, right heart failure and eventual death. Several reports showed that high mobility group box 1 (HMGB1) appears to be critical for the development of PH, the underlying mechanism, however has not been revealed. Experiments from the current study demonstrated that the HMGB1 level was elevated in the lung tissue and blood plasma of rats after chronic hypoxia exposure and monocrotaline treatment. The HMGB1 was originally located within nucleus and translocated to cytoplasm of pulmonary artery smooth muscle cells (PASMCs) upon hypoxia exposure, a process that appeared mediated by endogenous H2 O2 ...

PURPOSE OF REVIEW: To summarize results of the most recent trials on venovenous extracorporeal membrane oxygenation (VV-ECMO) in severe acute respiratory distress syndrome (ARDS) and to elaborate on the unmet needs regarding VV-ECMO management in this setting. RECENT FINDINGS: Although it was terminated early for futility (i.e., failure to demonstrate a difference in 60-day mortality of 20%), the ECMO to Rescue Lung Injury in Severe ARDS trial of VV-ECMO for severe ARDS reported a nonsignificant, but clinically important, reduction in mortality (35 vs...

Afatinib, a second-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has demonstrated a significant survival benefit over platinum-based chemotherapy in a first-line setting in advanced non-small-cell lung cancer (NSCLC) harboring EGFR exon 19 deletion. In addition, we and other groups have shown there to be favorable progression-free survival (PFS) outcomes, with acceptable toxicity profiles, with bevacizumab and first-generation EGFR-TKI combination therapy. On the basis of the above, we hypothesized that a combination of bevacizumab and afatinib could potentially improve efficacy...

BACKGROUND: Respiratory distress syndrome is one of the main causes of mortality in premature neonates. Treatment of these neonates with invasive mechanical ventilation has side effects such as chronic pulmonary diseases. Noninvasive ventilation, such as nasal continuous positive airway pressure (NCPAP) and nasal high-frequency oscillation ventilation (NHFOV), has shown to reduce the burden of chronic lung disease. NHFOV is a promising new mode of noninvasive ventilation and may reduce the need for mechanical ventilation and reduce possible complications...

Idiopathic pulmonary fibrosis (IPF) is an age-associated, progressive and irreversible fatal interstitial lung disease. Although many drugs have failed in clinical trials, these failures improved the understanding of the pathogenesis of IPF. Currently, there are two drugs approved for IPF that slow the progression of the disease. However, the prognosis for patients with IPF remains poor and the search continues for drugs that inhibit the pathogenic pathways active in IPF to further reduce or even halt the progression of the disease...

BACKGROUND: Reverse shoulder arthroplasty (RSA) is typically performed in patients with cuff tear arthropathy. A common type of RSA baseplate has a central peg and 4 peripheral screws inserting into the glenoid surface. Baseplate failure is a significant postoperative complication that reduces prosthetic longevity and usually requires revision surgery. This study evaluated the contribution of mechanical factors on initial baseplate fixation. MATERIALS AND METHODS: This study simulated glenoid baseplate loading in a RSA...

BACKGROUND: Microwave ablation is a therapeutic option for patients with lung malignancies who are not surgical candidates. However, reports on local recurrence have been limited to small case series or retrospective reports. This review was conducted to synthesize the evidence regarding local recurrence and adverse events after microwave ablation for primary non-small cell lung cancer or pulmonary metastases. METHODS: The PubMed, Embase, and Scopus databases were searched to identify peer-reviewed studies investigating microwave ablation of lung malignancies with local recurrence or adverse events as a primary outcome...

BACKGROUND: Multiple organ failure can develop after hemorrhagic shock (HS). Uric acid (UA) is released from dying cells and can be pro-inflammatory. We hypothesized that UA could be an alternative mediator of organ apoptosis and inflammation after HS. METHODS: ventilated male Wistar rats were used for the HS model. Two durations of shock (5 vs 60 min) were compared, and shams were instrumented only; animals were resuscitated and observed for 24h/72h. Caspases-(8/3), myeloperoxidase (MPO), TNF-α were measured in lungs and kidneys...

Respiratory failure is a significant problem within the pediatric population. A means of respiratory support that readily allows ambulation could improve treatment. The Pittsburgh Pediatric Ambulatory Lung (P-PAL) is being developed as a wearable pediatric pump-lung for long-term respiratory support and has previously demonstrated positive benchtop results. This study aimed to evaluate acute (4-6 hours) in vivo P-PAL performance, as well as develop an optimal implant strategy for future long-term studies. The P-PAL was connected to healthy sheep (n = 6, 23-32 kg) via cannulation of the right atrium and pulmonary artery...

PURPOSE OF REVIEW: Lung and esophageal surgery remain a curative option for resectable cancers. However, despite advances in surgical and anesthesia practices, the inclusion of patients with comorbidities that would have previously not been offered curative resection presents additional concerns and challenges. RECENT FINDINGS: Perioperative complication rates remain high and prolonged and/or painful recovery are common. Further, many patients face a permanent decline in their functional status, which negatively affects their quality of life...

BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are used to treat patients with nonsmall cell lung cancer (NSCLC) and EGFR driver mutations. Although some patients discontinued these treatments because of adverse events, it is unclear whether switching EGFR-TKI because of adverse events provides a benefit. METHODS: This retrospective study evaluated data from 22 patients with EGFR mutation-positive NSCLC who received at least two EGFR-TKIs that were switched because of adverse events (March 2011 to September 2017)...

Heart-lung transplantation (HLTx) is currently the best treatment for patients who have end-stage heart and lung failure. Idiopathic pulmonary arterial hypertension (IPAH) was the main indication for HLTx in the 1980s. However, when studies showed resolution of right ventricular dysfunction after double-lung transplantation (DLTx), this last procedure became the preferred option for end-stage IPAH. Currently, the main indication of HLTx is congenital heart disease (CHD), followed by acquired heart disease combined with pulmonary hypertension and/or intrinsic lung disease...
