Abstract Background Chylopericardium is a rare condition characterized by the accumulation of chyle in pericardial space. It most commonly caused thoracic duct injury. following esophagectomy extremely but can cause life-threatening complications. This report presents case chylopericardium post-esophagectomy, resulting cardiac tamponade and arrest. A systematic literature review was also conducted to facilitate understanding this condition. Case presentation 41-year-old male admitted our...

Abstract Background Cytomegalovirus infection manifests varying clinical characteristics and severity in diverse populations with different immune statuses. The signs symptoms of gastrointestinal involvement are nonspecific. Here, we present a case cytomegalovirus colitis an immunocompetent adolescent, which manifested as intestinal pseud-obstruction. Case presentation A 15-year-old man who had contracted novel coronavirus one month earlier was admitted to our hospital fever, abdominal pain,...

High-quality chest compression (CC) is the crux of survival for cardiac arrest patients. While, rescuers' position setting relative to patients during CC was unrecommended in present guidelines. We aimed assess impact settings on quality cardiopulmonary resuscitation (CPR) and test heterogeneity related characteristics.

Background Percutaneous catheter drainage (PCD) has been viewed as first-line treatment for pyogenic liver abscess (PLA), yet detailed guidance is lacking best practice of PCD. This study investigated characteristics patients with PLA who had received PCD, identified factors associated prolonged fever, and aimed to evaluate the relationship between timing PCD clinical improvement.Methods was a retrospective undergone over 7-year period. performed when liquefaction degree abscesses less than...

Abstract Purpose Developing countries need effective and efficient training curriculum for the point-of-care ultrasound (POCUS) in emergency department (ED). We have developed a new goal-directed focusing on critical POCUS procedures used ED. Methods To evaluate impact of ED physicians’ performance/self-confidence, we carried out quasi-experimental trial at center Peking Union Medical College Hospital, which trained two groups physicians using either traditional or curriculum. measured...

Aiming at the experimental test of body freedom flutter for modern high aspect ratio flexible flying wing, this paper conducts a wind tunnel on full-span wing model. The research content is summarized as follows: (1) finite element model and aeroelastic an unmanned aerial vehicle are established, structural dynamics characteristics obtained through theoretical analysis. (2) Based preliminary analysis results, design manufacturing completed, dynamic identified ground vibration test. Finally,...

Abstract Background Over the past decades, Klebsiella pneumoniae ( K. ) infections have been increasing and affected immunocompromised patients nosocomially communally, with extended-spectrum β-lactamase (ESBL) production becoming a major concern. Patients rheumatic autoimmune diseases, mostly receiving immunosuppressive therapy, are vulnerable to various infections, including . However, few investigated in this specific population. This study aimed identify factors associated ESBL mortality...

Gravel and sediment frequently build up in holes during the anchor cable installation process, which makes it harder to install causes reinforcement fail, can lead accidents. In this paper, a bit setup approach is proposed set drill at front of aid drilling. The feasibility established with DEM-MBD joint simulation proves correctness model. major elements affecting drilling effectivity have been studied by use ‘check + simulation’. effects exhibit that axial velocity working aperture are...

Abstract Background Noninvasive ventilation (NIV) is the recommended mode of used in acute respiratory failure secondary to an exacerbation chronic obstructive pulmonary disease (AECOPD). Recent data has shown that high-flow nasal cannula (HFNC) treatment can be alternative for patients with hypercapnic failure.
