cord-000254-bufbjdmw	2010	Interstitial lung disease (ILD) in infants and children comprises a large spectrum of rare respiratory disorders that are mostly chronic and associated with high morbidity and mortality. Interstitial lung disease (ILD) in infants and children represents a heterogeneous group of respiratory disorders that are mostly chronic and associated with high morbidity and mortality (around 15%) [1, 2] . These disorders, more prevalent in young children, include diffuse developmental disorders, lung growth abnormalities, neuroendocrine cell hyperplasia and pulmonary interstitial glycogenosis, surfactant dysfunction disorders, disorders related to systemic diseases, disorders of immunocompromised host, and disorders of normal host caused by various insults such as aspiration syndrome or infections [8] . Several studies in the adult literature have reported an increased incidence of EBV and CMV infection in patients with pulmonary fibrosis, associated with virus DNA-positive lung tissue biopsies in several cases [147] .
cord-000268-480d3yfv	2010	title: Diagnostic value of triggering receptor expressed on myeloid cells-1 and C-reactive protein for patients with lung infiltrates: an observational study The aim of the present study was to define whether expression of TREM-1 on cell membranes of neutrophils (nTREM-1), of monocytes (mTREM-1) and serum sTREM-1 may help in the diagnosis of acute bacterial infections for patients admitted with a new pulmonary infiltrate or pleural effusion. In conclusion, the presented results indicate that serum sTREM-1 and expression of TREM-1 on neutrophils and monocytes may serve as markers of CAP in patients with pulmonary infiltrates. Increased levels of soluble triggering receptor expressed on myeloid cells-1 in patients with acute pancreatitis Prognosis of community acquired pneumonia(CAP): value of triggering receptor expressed on myeloid cells-1 (TREM-1) and other mediators of the inflammatory response Diagnostic implications of soluble triggering receptor expressed on myeloid cells-1 in BAL fluid of patients with pulmonary infiltrates in the ICU

Hantavirus infection was verified with the detection of PUUV RNA in plasma (630,000 copies/ml) on the day of admission, while IgM and IgG were negative. Consecutive plasma samples were analysed for PUUV RNA with declining viral copy numbers until negative 16 days post onset of Fig. 1 Chest CT-scans of two European patients with hantavirus pulmonary syndrome. Concerning the cases of European hantavirus infection in our present report, there was only mild or no renal impairment at the time of admission, whereas the respiratory involvement was early and severe, consistent with acute respiratory distress syndrome (ARDS), fulfilling criteria of HPS according to CDC case definition [19] .

Cardiovascular support was limited to NA + dobutamine (DB), 546C88 was administered for up to 8 h at a fixed dose-rate of either i, 2.5, 5, 10 or 20 mg/kg/h iv. Methods: Fourteen cases were s~udied,their gestational age ranged from(27-32)ws.Continnous positive air way pressure was applied to six cases at Peep level from (3-6)cm H2o through nasal pronge,(group I),the other 8 cases were managed as routine,(group II).Blood gases, TcPO2,TcCo2,resp.rate,depth and pattern were monitored for assessment of tissue Oxygenation and ventilation, Results: Our rasults showed that early application of CPAP improve ventilation among (83.3%)of cases,while (16.7%)of cases need IMV.The cases of group II need IMV among (75%)of the studied cases during the second or the third day of life.
cord-005941-e4fvj54l	1992	Further clinical studies will be necessary to investigate the potential therapeutic benefits of surfactant substitution and the usefulness of pharmacologic manipulation of the secretory activity of alveolar type II cells in pulmonary medicine. The fate of secreted surfactant material seems to be determined by five mechanisms: -Intraalveolar catabolism -Phagocytosis and degradation by alveolar macrophages [110, 118] -Removal by the mucociliary escalator -Recycling into the alveolar type II cell -Redistribution into other surrounding tissue Clearance studies in rabbits [140] have shown that approximately 7% of radiolabeled phosphatidylcholine is removed via the upper airways in 24 h, suggesting that this pathway is only of minor importance. These studies may indicate that the acute effect of nitrogen dioxide on alveolar type II cells is enhanced surfactant lipid synthesis, while chronic low-dose exposure leads to a decrease in surfactant synthesis capacity.

The aim of this study was to evaluate the incidence, radiographic appearance, time of onset, outcome and risk factors of non-infectious and infectious pulmonary complications following liver transplantation. In univariate analysis (Table 1) , a statistically significant higher risk was demonstrated in cases of AHF patients, retransplantation, immunosuppression with OKT3, prolonged stay in ICU and AMV and in protracted pulmonary oedema; instead, surgical piggyback caval anastomosis is a factor reducing hazard. The present study, performed on a wider patient population, demonstrated, in univariate analysis, a significantly increased association of pulmonary infection with the following five risk factors: caval traditional anastomosis, retransplantation, OKT3 immunosuppression, ICU stay and AMV duration, pulmonary non-inflammatory abnormalities, such as effusion and atelectasis, and oedema.

In the United States, HPS is caused by at least four hantaviruses: the Sin Nombre virus (SNV, responsible for the Four Corners outbreak), the Black Creek Canal virus (isolated from the Florida cotton rat) [4] , the Bayou virus in Louisiana [5] , and the New York 1 hantavirus [6] . RNA viruses with segmented genomes, such as influenza virus, Since the first outbreak of hantavirus pulmonary syndrome (HPS) in 1993, understanding of the vast distribution and potential impact of hantaviruses has grown.

cord-007696-83v9yfa6	2005	Idiopathic pulmonary fibrosis (IPF) is a chronic fibrosing lung disease limited to the lungs and associated with the histologic appearance of usual interstitial pneumonia (UIP) on surgical lung biopsy. Factors that predict poor outcome include older age, male gender, severe dyspnea, history of cigarette smoking, severe loss of lung function, appearance and severity of fibrosis on radiological studies, lack of response to therapy, and prominent fibroblastic foci on histopathologic evaluation. With greater comprehension of the clinical relevance of the different histopathological subgroups that make up the idiopathic interstitial pneumonias, the term idiopathic pulmonary fibrosis (IPF) is now reserved to patients with idiopathic usual interstitial pneumonia (UIP) on surgical lung biopsy. Tang In a recent study, human T-lymphtropic virus type I (HTVL-I) positive IPF patients had more affected lung parenchyma, demonstrated traction bronchiectasis with honeycomb change, and exhibited increased levels of specific cytokines that correlated with activated T-cells in the bronchoalveolar lavage fluid (BALF).
cord-007797-toam6r5y	2019	Community acquired pneumonia refers to an acute infection of the lung in patients who did not meet any of the criteria for HCAP, presenting select clinical features (e.g., cough, fever, sputum production, and pleuritic chest pain) and accompanied by an acute infiltrate on a chest radiograph. Chest radiographs are of limited value in predicting the causative pathogen but are of good use to determine the extent of pneumonia and to detect complications (i.e., cavitation, abscess formation, pneumothorax, pleural effusion), to detect additional or alternative diagnoses, and, in some cases, to guide invasive diagnostic procedures. Risk factors for the development of staphylococcal pneumonia include underlying pulmonary disease (e.g., COPD, carcinoma), chronic illnesses (e.g., diabetes mellitus, renal failure), or viral infection. The lower lobes contrast-enhanced CT image shows a mixed opacity of consolidation (arrow) and ground-glass opacity (small arrows) consistent with lobar pneumonia tend to be affected, and the radiographic pattern is similar to that seen with S.

cord-010697-0eutz8xy	2020	Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a life-saving technology that provides transient respiratory and circulatory support for patients with profound cardiogenic shock or refractory cardiac arrest. The interaction of blood components with the biomaterials of the extracorporeal membrane elicits a systemic inflammatory response which may increase pulmonary vascular permeability and promote the sequestration of polymorphonuclear neutrophils within the lung parenchyma. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a life-saving technology providing respiratory and circulatory support in patients with refractory cardiogenic shock or cardiac arrest [1] and which may give time to plan future therapeutic decisions such as the insertion of long-term cardiac assist devices or heart transplantation (HTX) [2] . Alveolar edema and decreased pulmonary artery perfusion lead to lung parenchymal ischemia which in turn maintains chronic inflammation and promotes neoangiogenesis and fibrosis generation and polymorphonuclear cells (PMNs), and triggers the intrinsic coagulation cascade, resulting in the rapid generation of thrombin and fibrin within the systemic circulation [13] .

Based on the course of the disease, the diagnostic imaging demonstrations of Rhodococcus equi pulmonary infection can be divided into early stage, showing round liked fl aky blurry shadows surrounding unilateral hilum that has blurry boundary; middle stage (parenchymal change), showing central sphere liked high density shadow surrounding unilateral hilum, in parenchymal changes and with clear boundary; advanced stage (necrosis) showing secondary cavity of the pulmonary mass, possibly with hydropneumothorax and pleurisy.
cord-016973-s32jp0ej	2016	Understanding the underlying pulmonary physiologic changes that come with pregnancy as well as those conditions which are unique to the pregnant patient will help arrive at the correct diagnosis and management. Recognizing that the gravid patient has other physiologic changes that contribute to decreased respiratory reserve, increased risk of aspiration, infection, and difficult airway can help in managing these patients acutely. The most common causes of non-cardiogenic acute pulmonary edema in pregnancy are the use of tocolytic agents, fluid overload, preeclampsia, sepsis, trauma or following aspiration of gastric contents [6, 7] . A partial pressure of carbon dioxide within the normal range of 36-40 on an arterial blood gas can be a early sign of imment respiratory failure in the gravid patient. Some of the risk factors for pneumonia in pregnancy include anemia, asthma, antepartum corticosteroids given to enhance fetal lung maturity, and the use of tocolytic agents to induce labor [25] .
cord-017016-twwa9djm	2008	These occult aspirations may lead to interstitial fibrosis, and perhaps account for the 20% to 54 % incidence of associated and unexplained pulmonary fibrosis in patients with esophageal abnormalities, most commonly hiatal hernia or simple reflux,39,40 The role of reflux in asthma, chronic bronchitis, chronic cough, recurrent pneumonia, cystic fibrosis, and sudden infant death syndrome has been reviewed by Allen et al. 130 In their reviews, Phillips and Rao l3l and Penner and colleagues130 note that similar predisposing factors as those with community-acquired pneumonia, such as aspiration and abscess formation, pertain to this entity, but the location helps distinguish it from the other typical sites of aspiration, When in the upper lobes, it appears to progress through necrotizing pneumonia with thrombosis of arteries (pulmonary and bronchial) and veins, [129] [130] [131] Although not strictly abiding by the foregoing definition (of localization in upper lobe), in one case total unilateral lung gangrene was attributed to hilar vessel involvement following treatment of a massive hilar recurrence of Hodgkin''s disease.

cord-017581-6lubp7io	2019	Pregnant patients can suffer from the same respiratory diseases as the general population in addition to unique syndromes of pregnancy (such as pre-eclampsia and tocolytic induced pulmonary edema, and pregnancy induced cardiomyopathy). Low pulmonary reserves that arise from reductions in functional residual capacity (caused by the gravid uterus and changes in the chest wall morphology) [1] and increased oxygen consumption make pregnant women develop hypoxemia more rapidly during apnea [4] . The most common causes of non-cardiogenic acute pulmonary edema in pregnancy are, fluid overload, preeclampsia, tocolytic agents, sepsis, trauma or following aspiration of gastric contents [6, 7] . A partial pressure of carbon dioxide within the normal range of 36-40 on an arterial blood gas can be an early sign of imminent respiratory failure in the gravid patient.

cord-017771-g72qaoub	2019	Besides the evaluation of these conditions, imaging is routinely used for the assessment of various catheters and tubes commonly used in ICUs. The common pulmonary parenchymal disease processes in ICU patients include hydrostatic pulmonary edema, acute respiratory distress syndrome (ARDS), atelectasis, pneumonia, aspiration, and pulmonary hemorrhage. Indistinctness of pulmonary vasculature is subtle but often the most useful radiographic sign of early interstitial edema in ICU patients. The CT findings of hydrostatic pulmonary edema include smooth interlobular septal thickening, ground-glass opacities, consolidation, and pleural effusions ( Fig. 7.4) . The diagnosis of pneumonia in ICU patients is often challenging as the airspace opacities seen on chest radiographs in these patients can be caused by atelectasis, aspiration, pulmonary hemorrhage, noninfectious lung inflammation (e.g., drug reaction), pulmonary edema, or ARDS [12] . The radiographic abnormalities commonly seen with aspiration are patchy ill-defined ground-glass opacities, nodular opacities, or consolidation in the dependent regions of the lungs (Fig. 7.10 ).

Hematologic malignancy patients treated with chemotherapy or chest wall radiation therapy, or those who proceed to receive a HSCT may develop a wide variety inflammatory noninfectious lung disorders that ultimately may lead to pulmonary fibrosis. The diagnosis of drug-induced respiratory disease often is complex because: (1)1 patients may be exposed to several pneumo-toxic drugs concurrently or in sequence due to earlier treatment failure; (2)2 time to onset of pulmonary toxicity may be delayed, making it difficult to ascertain which agent is responsible for the pulmonary reaction; (3)3 the combination of drugs to treat malignant hematologic conditions may lead to unexpected drug interactions, producing enhanced toxicity compared with the toxicity of each agent considered separately; and (4)4 radiation therapy to the chest or TBI.

Small-for-size syndrome develops in a patient who received a donor graft that was less than 1 % of the recipient''s body weight and is caused by decreased hepatic arterial flow in response to increased portal venous flow and pressure. The major criteria for the diagnosis of the hepatorenal syndrome are as follows: (1) advanced hepatic disease and portal hypertension; (2) low glomerular filtration rate (serum creatinine >1.5 mg/dL or creatinine clearance <40 mL/ min); (3) absence of nephrotoxic drug use, shock, systemic infection, or recent fluid losses; (4) lack of sustained improvement after diuretic withdrawal and volume resuscitation with 1.5 L of normal saline; (5) proteinuria (<500 mg/dL); and (6) no ultrasound evidence of urinary obstruction or parenchymal disease.

The diagnosis of leishmaniasis is based on the microscopical demonstration of Leishmania amastigotes in the relevant tissue aspirates or biopsies such as bone marrow, spleen, lymph nodes, or liver, skin slit smears, or in the peripheral blood buffy coat [ 19 ] . The important helminthic parasites that cause lung diseases include cestodes ( Echinococcus granulosus and Echinococcus multilocularis ), trematodes ( Schistosoma haematobium , Schistosoma mansoni , Schistosoma japonicum , and Paragonimus westermani ), and nematodes ( Ascaris lumbricoides , Ancylostoma duodenale , Necator americanus , Strongyloides stercoralis , Wuchereria bancrofti , Brugia malayi , Brugia timori , Dirofi laria immitis , Dirofi laria repens , Toxocara canis or cati , and Trichinella spiralis ).

In patients with HP the thoracic HRCT helps us come close to the differential diagnosis of infectious and non-infectious pulmonary complications by integrating image findings and clinical data.
cord-023311-7wqdlha4	2010	Methods We determined the usefulness of preoperative lung function by spirometry in predicting regression of pulmonary hypertension after surgical correction of mitral stenosis among 20 patients who underwent mitral valve surgery at Philippine Heart Center from July to December 2009. Elderly patients exhibited a signifi cantly higher mortality rate that was independently associated with the following: age; residence status; confusion, urea, respiratory frequency and blood pressure (CURB) score; comorbid conditions; and failure of initial therapy. Methods A total of 40 patients (Male: 50%; Female: 50%) admitted and diagnosed with HAP at our Center were followed up to investigate the rate of adherence of physicians on the diagnosis and treatment of HAP based on Level I and II ATS/IDSA 2008 recommendations and to determine its association with outcome (mortality, mechanical ventilation, ICU stay, hospital stay).
cord-023509-tvqpv6fp	2011	As a general rule, exposure to silica dust extends over many years, often 20 or more, before the symptoms of silicosis first appear: by the time the disease becomes overt clinically, much irreparable damage has been inflicted on the lungs. Confusingly, the term ''acute silicosis'' has since been applied to a further effect of heavy dust exposure in tunnellers, sand blasters and silica flour workers, namely pulmonary alveolar lipoproteinosis (see below), 71, 72 whilst the terms ''accelerated silicosis'' or ''cellular phase silicosis'' have been substituted for ''acute silicosis'' in referring to the rapid development of early cellular lesions. Asbestosis is defined as diffuse interstitial fibrosis of the lung caused by exposure to asbestos dust. The finely divided fume of several metals is highly toxic to the lungs and capable of producing severe acute and chronic damage to both the conductive airways and the alveoli, resulting in acute tracheobronchitis and bronchiolitis, diffuse alveolar damage, obliterative bronchiolitis and pulmonary fibrosis.
cord-024183-1mrdjc39	2013	After airway occlusion at mid-expiration, there is a biphasic change in P ao : the immediate rapid rise in P ao represents the resistive pressure drop across the conducting airways and is followed by a secondary slower increase in P ao (often referred to as P dif ) generally attributed to stress recovery in the respiratory tissues (lung and chest wall) and gas redistribution associated with ventilation inhomogeneity (Bates et al. To describe flow (F), lung volumes (V), and respiratory pressure (P) measurements together with resistance (R) and compliance (C) measurements in restrictive lung diseases, obstructive lung diseases, and neuromuscular disorders (NMD) decrease in TLC, in general, is relatively less than that of VC because of normal chest wall recoil and inspiratory muscle function in most patients (Martinez and Flaherty 2006) .
cord-026005-f2khcjdy	2017	Microscopic examination of properly collected, stored, and processed samples may reveal many erythrocytes and siderophages in pulmonary hemorrhage or left-sided heart failure; inclusion bodies or syncytial cells in viral pneumonias; increased number of leukocytes in pulmonary inflammation; abundant mucus in asthma or equine recurrent airway obstruction (RAO); the presence of pulmonary pathogens, such as parasites, fungi, and bacteria; or tumor cells in cases of pulmonary neoplasia. The portal of entry for the respiratory form is typically aerogenous, and the disease is generally transient; thus the primary viral-induced lesions in the nasal mucosa and lungs are rarely seen at necropsy unless complicated by secondary bacterial rhinitis, pharyngitis, or bronchopneumonia. Laryngeal edema occurs in pigs with edema disease; in horses with purpura hemorrhagica; in cattle with acute interstitial pneumonia; in cats with systemic anaphylaxis; and in all species as a result of trauma, improper endotracheal tubing, inhalation of irritant gases (e.g., smoke), local inflammation, and animal species is classified as fibrinous, catarrhal, purulent, or granulomatous (Figs.
cord-034294-ti1cc24m	2020	Trx effectively prevents the progression of COPD by regulating redox status and protease/anti-protease balance, blocking the NF-κB and MAPK signalling pathways, suppressing the activation and migration of inflammatory cells and the production of cytokines, inhibiting the synthesis and the activation of adhesion factors and growth factors, and controlling the cAMP-PKA and PI3K/Akt signalling pathways. EPAC and PKA inhibit the human airway smooth muscle induced by a cigarette smoke extract (CSE) by blocking the activation of the NF-κB and ERK, respectively, and by releasing neutrophil chemokine IL-8, which together exert anti-inflammatory effects. 101 In COPD, increases in cAMP levels, activation of PKA and enhanced protein phosphorylation have the potential to reduce inflammation and immunomodulation, relax airway smooth muscle, inhibit chemotaxis and abnormal release of inflammatory and cytotoxic mediators, and reduce proliferation and migration of inflammatory cells. 135 The PI3K/Akt signalling pathway plays an important role in COPD by regulating inflammatory cell activation, inflammatory mediator release and airway remodelling.

Risk factors for postoperative bleeding in cardiac surgery patients include advanced age, low body weight, nonelective surgery, CPB time over 150 min, high complexity of procedure, perioperative use of antiplatelet agents, and use of over 5 bypass grafts [58] . Operative risk factors include low cardiac output syndrome, more than 3 U of packed RBCs (or massive transfusion), isolated valve surgery, and development of postoperative pneumonia [68, 69] . While routine use of the pulmonary artery catheter became less prevalent over the previous decades, it still holds a central role in the postoperative care of cardiac surgery patients.

cord-255519-tcobane8	2020	The population of patients who benefit from both cardiac and pulmonary rehabilitation is increasing as the population ages and heart disease remains a leading cause of global morbidity and mortality. Many patients with stroke, vascular disease, or other conditions can be included in active cardiac and pulmonary rehabilitation programs or benefit from the application of cardiopulmonary rehabilitation principles to their rehabilitation. For secondary prevention in patients with known cardiopulmonary disease, exercise should be at a safe level at 60% or more of the maximum heart rate to achieve a training effect. 82 Rehabilitation is focused on a program that resembles exercise for patients with heart failure, with the addition of close monitoring of oxygen saturation and the use of appropriate levels of supplemental oxygen to prevent hypoxemia. Individuals who are disabled tend to have lower activity levels, which puts them at increased risk of cardiac and pulmonary disease and may present obstacles for a standard rehabilitation program for a person who is newly disabled and who has preexisting cardiopulmonary limitations.

[38] [39] [40] [41] [42] [43] [44] [45] Two randomized controlled trials of singing group interventions in COPD report improvements in quality of life and reduction in anxiety, although not in lung function. 49 Arnold and colleagues showed that improvements in quality of life scores after PR were associated with increases in measures of self-efficacy and suggested that "focussing more explicitly on the enhancement of perceptions of personal control in COPD patients may be an important aim of pulmonary rehabilitation".

It is also important to consider risk factors for possible chronic thromboembolic pulmonary hypertension (CTEPH) or chronic thromboembolic disease in both the symptomatic and asymptomatic patient, which are helpfully listed in the new guidance [17] [18] [19] . [24] also demonstrated that ILD-related PH patients, at right heart catheterisation, had lower mPAP and PVR when compared to their idiopathic pulmonary arterial hypertension (PAH) cohort; despite these findings, mortality was high in both groups.

Nifedipine and amlodipine were found to be associated with significantly improved mortality and a decreased risk for intubation and mechanical ventilation in elderly patients hospitalized with COVID-19. Nifedipine and amlodipine were found to be associated with significantly improved mortality and a decreased risk for intubation and mechanical ventilation in elderly patients hospitalized with COVID-19.

cord-293613-xnos7iud	2020	The 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) document AECOPD definition slightly differs from this as "an acute worsening of respiratory symptoms that results in additional therapy." This definition requires the patient to seek or use treatment and is an example of a health care use (HCU) exacerbation in which the patient or clinician decides whether treatment is warranted. This approach has been widely accepted in research, using several validated patient-reported outcome (PRO) tools such as symptom/treatment diary cards and questionnaire tools such as the EXACT (Exacerbations of Chronic Obstructive Pulmonary Disease Tool) and CAT (The COPD Assessment Test).

cord-305838-i0ck2oo0	2020	Home measurement of peak expiratory flow (PEF) using an inexpensive portable handheld device is already a guideline-recommended option to facilitate patient self-management in asthma and in the diagnosis of occupational asthma, but its role is less well defined in COPD. 37 Electronic portable spirometers have been studied and found to be comparable to conventional laboratory spirometry in several chronic respiratory conditions, such as asthma and COPD, cystic fibrosis, idiopathic pulmonary fibrosis, and post-lung and hematopoietic stem cell transplant monitoring. Oscillometry is emerging as an alternative form of pulmonary function testing that offers some advantages over conventional PFTs. 54 It has been shown to be more sensitive than spirometry in early diagnosis of COPD, 55, 56 to correlate better with respiratory symptoms and asthma control 57,58 as well as in identifying spirometrically silent episodes of biopsy-proven acute graft rejection following lung transplant.
cord-312978-i41l4mtx	2020	A thoracic CT scan searching an underlying pathology revealed overdistension of the right hemithorax with parenchymal air cystic lesions involving the external segment of the middle lobe conducting to a malformation cystic adenomatoid, a fairly abundant right hydropneumothorax responsible for a compressive effect on the adjacent pulmonary parenchyma, and inflammation of the pleura ( Figure 2 ). Regarding the localization, the right lung is more frequently affected by pulmonary blastoma than the left, which is consistent with a previous study involving adult patients [6] . When performing a lobectomy for type II or III PPB, involved pleural surfaces should be resected with the primary tumor and involved pulmonary lobe. Pneumoblastoma in children is a rare, aggressive tumor that shows up with nonspecific clinical and radiological signs which may often delay diagnosis, so the prognosis may be so bad.

cord-320447-nq9f1gmu	2020	Results: Compared to healthy volunteers, COVID-19 patients showed significant reduction in BV5 (pulmonary blood volume contained in blood vessels of <5 mm(2)) expressed as BV5/(Total pulmonary blood volume) (p<0.0001), and significant increases in BV5-10 and BV 10 (pulmonary blood volumes contained in vessels between 5 and 10 mm(2) and above 10 mm(2), respectively) (p<0.0001). Conclusions: COVID-19 patients display striking anomalies in the distribution of blood volume within the pulmonary vascular tree, consistent with increased pulmonary vasculature resistance in the pulmonary vessels below the resolution of CT. These results suggest that while the pathological changes to the pulmonary vasculature implicated in pulmonary vascular disease (PVD), collectively termed "pulmonary vascular remodeling", occur primarily below the resolution of CT scans, those processes do have a measurable effect on larger, more proximal vessels. In this study we assessed the use of novel CT-derived measures of pulmonary blood volume and pulmonary vascular density in patients with COVID-19.
cord-320959-sgdqhtns	2020	In membrane biophysics, Vitamin E is a linactant and a potent modulator of lateral phase separation that effectively reduces the line tension at the two-dimensional phase boundaries and thereby exponentially increases the surface viscosity of the pulmonary surfactant. Supplementation of pulmonary surfactants which retain moderate level of cholesterol and 10 controlled hypothermia for patients are recommended when the hypothesis that the line-active property of the vitamin derivative drives the pathogenesis of EVALI holds. Currently, there are 5 five established non-antioxidative properties of Vitamin E in the biological system: i) its ability to induce gel-liquid crystalline phase transition, ii) its active deposition in the lipid droplet of macrophages, iii) its modulation of the antidiabetic cascade involving diacylglycerol kinase (DGK) and protein kinase C (PKC), iv) its activation of the xenobiotic-sensing pregnane X receptor (PXR) signaling, and v) its ability to modulate lateral phase separation.

cord-322919-5ty35rsy	2020	When stratifying for SVRI, patients with an SVRI value below the cohort median had also more severe oxygenation impairment and lower TPR, despite a similar degree of CXR infiltrates. CONCLUSIONS: In the early stages of COVID‐19 infection the hemodynamic profile is characterized by a hyperdynamic circulatory state with high CI and low SVRI, while the right heart is functionally unaffected. In this study, we found that in the early stages of the disease, COVID-19 infection leads to a hyperdynamic circulatory state characterized by an elevated CI and low SVRI. The right heart function was unaffected, and pulmonary pressures were normal, despite the high CI, particularly in the low SVRI range. Lung recruitability in COVID-19 is moderately low (Pan et al., 2020) and blood diversion with cardiac output reduction may justify the reported oxygenation improvement at high Positive End Expiratory Pressure (PEEP).

cord-325461-q8igdvq4	2014	We consider the factors that influence pulmonary arterial pressure, both in normal lungs and in the presence of ARDS, including the important effects of mechanical ventilation. (Am J Respir Crit Care Med 182:1123–1128, 2010) have recently reported that elevated pulmonary vascular resistance (PVR) and TPG were independently associated with increased mortality in ARDS, in a large trial with protocol-defined management strategies and using lung-protective ventilation. Studies were identified after a literature search using key terms (ARDS or acute respiratory distress or ALI or acute lung injury) together with any of the following: pulmonary haemodynamics, pulmonary artery pressure, pulmonary vascular resistance, pulmonary vascular dysfunction, right ventricle, right ventricular failure, acute cor pulmonale, or pulmonary artery catheter. There are very few studies which have measured pulmonary vascular resistance in ARDS patients ventilated with lower tidal volumes, perhaps due to the reduction in the use of the pulmonary artery catheter just as lung-protective ventilation was gaining widespread acceptance [60] .

Development of lung cancer occurs with multiple, complex, stepwise genetic and epigenetic changes involving allelic losses, chromosomal instability and imbalance, mutations in tumor suppressor genes (TSGs) and dominant oncogenes, epigenetic gene silencing through promoter hypermethylation, and aberrant expression of genes participating in control of cell proliferation and apoptosis [7] . In recent years, atypical adenomatous hyperplasia (AAH) has been recognized as a precursor lesion for peripheral pulmonary ACs. This lesion is defined as "a localized proliferation of mild to moderately atypical cells lining involved alveoli and, sometimes, respiratory bronchioles, resulting in focal lesions in peripheral Part IV Molecular Pathology of Human Disease alveolated lung, usually less than 5 mm in diameter and generally in the absence of underlying interstitial inflammation and fibrosis" (Figure 18 .8) [36] .
