Abstract
Pulmonary embolism (PE) is the third most common cause of cardiovascular death. Every specialty of medical practitioner will encounter PE in their patients, and should be prepared to employ contemporary strategies for diagnosis and initial risk-stratification. Treatment of PE is based on risk-stratification, with anticoagulation for all patients, and advanced modalities including systemic thrombolysis, catheter-directed therapies, and mechanical circulatory supports utilized in a manner paralleling PE severity and clinical context.

Abstract
Pulmonary embolism (PE) is the third most common acute cardiovascular disease. The risk of PE increases with age and mortality is high. Patients are stratified into hemodynamically stable versus unstable patients, as this has important implications for diagnosis and therapy. Since clinical signs and symptoms of acute PE are nonspecific, the clinical likelihood of PE is estimated to guide diagnostic pathways. D-dimer testing is performed in hemodynamically stable patients with low or intermediate probability of PE and the visualization of thromboembolism and its sequelae is commonly achieved with computed tomography pulmonary angiography (CTPA), supplemented by ultrasound techniques. With confirmed PE, another risk stratification estimates disease severity and defines intensity and setting of the ensuing treatment. The therapeutic spectrum ranges from outpatient treatment with initial oral anticoagulation to thrombolytic or interventional treatment in the intensive care unit or catheterization laboratory. In single cases, even acute surgical thrombectomy is attempted.

Abstract
Pulmonary circulation is crucial in the human circulatory system, facilitating the oxygenation of blood as it moves from the right heart to the lungs and then to the left heart. However, during critical illness, pulmonary microcirculation can be vulnerable to both intrapulmonary and extrapulmonary injuries. To assess these potential injuries in critically ill patients, critical point-of-care ultrasound can be used to quantitatively and qualitatively evaluate the right atrium, right ventricle, pulmonary artery, lung, pulmonary vein, and left atrium along the direction of blood flow. This assessment is particularly valuable for common ICU diseases such as acute respiratory distress syndrome (ARDS), sepsis, pulmonary hypertension, and cardiogenic pulmonary edema. It has significant potential for diagnosing and treating these conditions in critical care medicine.

Abstract
The ideal approach to hemodynamically unstable patients requires the quick identification of the type of shock and its etiology. This can be a challenge in critically ill patients due to the limited information, the wide number of differential diagnosis and the need for fast intervention. Point-of-care ultrasound (POCUS) is a non-invasive, low-cost, real-time and reliable tool used to rapidly and accurately assess hemodynamically unstable patients at the bedside. It can support diagnosis, tailor therapy and guide further workup, especially in patients deemed too unstable to undergo other imaging studies. The authors describe the case of a patient in obstructive shock due to pulmonary embolism, in which McConnell sign was identified by bedside echocardiography, before lab tests and pulmonary computerized tomography angiogram results were obtained

Abstract
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV‑2), is now a global pandemic. This virus primarily affects the respiratory tract and causes lung injury characterized by acute respiratory distress syndrome. Although the pathophysiology of COVID-19 is not yet clear, the most widely accepted mechanism is systemic inflammation. A clinically significant effect of the inflammation is coagulopathy. As a result of this effect, patients are found to have a high risk of venous thromboembolism. Studies have reported a high incidence of thrombotic complications in critically ill patients with COVID-19. In this review, we discuss the most updated evidence on the pathophysiology, diagnosis, and treatment of the coagulopathy of COVID-19. Prophylactic anticoagulation is recommended for all in-patients with COVID-19. Those with a higher risk of developing thromboembolic events or who have already developed venous thromboembolism should be treated with therapeutic anticoagulation. We also discuss post-discharge prophylaxis for high-risk patients and some newly proposed treatments for the hypercoagulability that could improve the outcomes of the affected patients.

Abstract
Lung Ultrasound in Differential Diagnosis of Dyspnea Abstract. Lung ultrasound offers an immediate diagnosis in accordance with the clinical examination in many causes of dyspnea: pleural effusion, pulmonary edema, pneumonia, pulmonary embolism and interstitial lung diseases. At first level exam, CXR, despite its intrinsic limitations and low accuracy, may still play a relevant role. CT scan remains the gold standard, but it requires patient transportation and use of radiation, which precludes an extensive use especially within the same patient. Lung ultrasound, after proper training of the physician, is able to provide greater accuracy than CXR and similar accuracy to the CT scan.

Abstract
Bedside lung ultrasound (LUS) in emergency rooms and intensive care units can serve as a tool to diagnose common lung pathologies, monitor their course and guide clinical management. LUS requires only a few minutes and is a useful extension of the physical examination. Fractures of the ribs as well as the sternum are seen well on ultrasound. Minute pleural fluids (effusion, hemtothorax) are detectable. LUS is able to detect the sound of lung water and thus to differentiate a cardiogenic pulmonary edema from chronic obstructive lung disease. Inflammatory lung diseases such as pleuritis and pneumonia are better seen than on chest X‑ray. LUS should replace chest X‑ray in the diagnosis of ambulant acquired pneumonia. In ventilator-associated pneumonia and atelectasis, LUS measures the presence of lung consolidation as well as dynamic changes und reventilation. A heart-lung-vessel integrated triple ultrasonography according to clinical findings can help with the diagnosis of pulmonary embolism and should be a necessary weapon for the physicians, especially in emergency departments.

Abstract
BACKGROUND The digestive tract is the maximal immunizing tissue in the body, and mucosal integrity and functional status of the gut is very important to maintain a healthy organism. Severe infection is one of the most common causes of gastrointestinal dysfunction, and the pathogenesis is closely related to endotoxemia and intestinal barrier injury. Bifidobacterium is one of the main probiotics in the human body that is involved in digestion, absorption, metabolism, nutrition, and immunity. Bifidobacterium plays an important role in maintaining the intestinal mucosal barrier integrity. This study investigated the protective mechanism of Bifidobacterium during ileal injury in rats.
AIM To investigate the effects of Bifidobacterium on cytokine-induced neutrophil chemoattractant (CINC) and insulin-like growth factor 1 (IGF-1) in the ileum of rats with endotoxin injury.
METHODS Preweaning rats were randomly divided into three groups: Control (group C), model (group E) and treatment (group T). Group E was intraperitoneally injected with lipopolysaccharide (LPS) to create an animal model of intestinal injury. Group T was intragastrically administered Bifidobacterium suspension 7 d before LPS. Group C was intraperitoneally injected with normal saline. The rats were killed at 2, 6 or 12 h after LPS or physiological saline injection to collect ileal tissue samples. The expression of ileal CINC mRNA was evaluated by reverse transcription-polymerase chain reaction (RT-PCR), and expression of ileal IGF-1 protein and mRNA was detected by immunohistochemistry and RT-PCR, respectively.
RESULTS The ileum of rats in Group C did not express CINC mRNA, ileums from Group E expressed high levels, which was then significantly decreased in Group T (F = 23.947, P < 0.05). There was no significant difference in CINC mRNA expression at different times (F = 0.665, P > 0.05). There was a high level of IGF-1 brown granules in ileal crypts and epithelial cells in Group C, sparse staining in Group E, and dark, dense brown staining in Group T. There was a significant difference between Groups C and E and Groups E and T (P < 0.05). There was no significant difference in IGF-1 protein expression at different times (F = 1.269, P > 0.05). IGF-1 mRNA expression was significantly different among the three groups (P < 0.05), though not at different times (F = 0.086, P > 0.05).
CONCLUSION Expression of CINC mRNA increased in the ileum of preweaning rats with endotoxin injury, and exogenous administration of Bifidobacterium reduced CINC mRNA expression. IGF-1 protein and mRNA expression decreased in the ileum of preweaning rats with endotoxin injury, and exogenous administration of Bifidobacterium prevented the decrease in IGF-1 expression. Bifidobacterium may increase IGF-1 expression and enhance intestinal immune barrier function in rats with endotoxin injury.

Abstract
BACKGROUND Pulmonary infarction is an infrequent complication of pulmonary embolism. Traditionally, it has been regarded as a sign of worse outcome because ischemia can only occur by the simultaneous failure of all oxygenation sources to the area of infarct, but supporting evidence is limited. METHODS We identified 74 cases of pulmonary infarction over 5 years at a single academic center via review of radiographic reports. Contrast-enhanced chest CT scans were examined to confirm evidence of pulmonary infarction, and patient clinical characteristics and imaging results were studied. RESULTS Survival to discharge was high (97%). Patients most commonly presented with dyspnea (69%), chest pain (46%), and swelling or pain in the lower extremities (31%), while underlying risk factors included history of malignancy (41%) and surgery within 30 days (24%). Many patients had concurrent cardiovascular (59%) and pulmonary disease (22%). Infarction disproportionately affected the lower lobes. CONCLUSIONS Survival after diagnosis of pulmonary infarction is comparable to uncomplicated pulmonary embolism, suggesting that outcome is not worse. While emboli occurred in multiple lobar sites, pulmonary infarction occurred most commonly in the lower lobes, suggesting unique underlying physiological mechanisms in pulmonary infarction development.
