All autopsy studies demonstrated widespread thrombosis and alveolar-capillary microthrombi as the cause of death among patients with COVID-19. The autopsy studies are the gold-standard for diagnostic accuracy and therapeutic strategies for any clinical scenarios. The author initially observed that patients already taking therapeutic dose of oral direct factor Xa inhibitors for an unrelated reason, have significantly better survival rates than those not taking any anticoagulants. This influenced the author to conduct a retrospective chart review of the hospitalized patients in Jackson Hospital (Alabama) to evaluate the effect of variable doses of anticoagulation among COVID-19 patients. The study found that serum inflammatory bio-marker D-dimer trends are associated with changes in oxygen requirement among patients with COVID-19, if patients present at an early stage, and titration of Enoxaparin (anticoagulation) dose based on D-dimer trends leads to increased patient survival.

Meijin Yuan Department of Nursing, The First Affiliated Hospital of Hebei North University, Zhangjiakou 075000, Hebei, China.
Objective: To explore the clinical efficacy of the interactive humanistic nursing model in emergency rescue of epidemic outbreaks.
Methods: This was a retrospective study. A total of 200 patients with novel coronavirus pneumonia (NCP) admitted to The First Affiliated Hospital of Hebei North University between December 2022 and March 2023 were selected and divided into the observation group(n=100) and the control group(n=100) according to different nursing methods used.
Aortoiliac arterial thrombosis and renal artery stenosis in a patient with neonatal multisystem inflammatory syndrome: a case report and review of literature.

Division of Neonatology, Department of Pediatrics, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand.
Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.

Institute of Bioengineering, School of Engineering, École Polytechnique Fédérale de Lausanne (EPFL), 1015 Lausanne, Switzerland.
Here, we present Link-Seq, a highly efficient droplet microfluidic method for combined sequencing of antibody-encoding genes and the transcriptome of individual B cells at large scale. The method is based on 3' barcoding of the transcriptome and subsequent single-molecule PCR in droplets, which freely shift the barcode along specific gene regions, such as the antibody heavy- and light-chain genes. Using the immune repertoire of COVID-19 patients and healthy donors as a model system, we obtain up to 91.

Department of Thoracic Medicine, Chang Gung Memorial Hospital at Linkou, Taoyuan, Taiwan.
Background: Non-pharmaceutical interventions (NPIs) were widely used during the coronavirus disease 2019 (COVID-19) pandemic, however their impact on acute asthma exacerbations (AEs) is not well studied.
Methods: We had retrospectively collected patients with asthma AEs between 2019 and 2020 and retrieved data from the Chang Gung Research Database, including clinical manifestations, medications, pulmonary function, clinic and emergency department visits and hospitalizations.
Results: A total of 39,108 adult patients with asthma were enrolled, of whom 1502 were eligible for analysis.

Assistant professor, Oral and Dental Disease Research Center, Department of Operative Dentistry, Faculty of Dentistry, Zahedan University of Medical Sciences, Zahedan, Iran.
Aim: Tooth sensitivity caused by exposed dentin tubules is a common clinical problem requiring correct treatment methods. Owing to the spread of the COVID-19 virus, it has become common to use different mouthwashes, including 1.5% hydrogen peroxide (HP), before dental procedures.
