Acute pulmonary embolism (PE) is a life-threatening condition in patients with Coronavirus disease-2019 (COVID-19). Computed tomography pulmonary angiography is the preferred test to confirm the diagnosis. However, computed tomography pulmonary angiography is expensive and is not available in every clinic. ⋯ A decrease in eosinophil levels, whereas an increase in CLR, D-dimer, and CRP may predict PE. Elevated CLR is highly predictive of PE and is associated with increased mortality risk. COVID-19 patients with a CLR level above 81 should be investigated for PE.

Macrophages in the synovium, as immune cells, can be polarized into different phenotypes to play an anti-inflammatory role in the treatment of osteoarthritis. In this study, bibliometric methods were used to search the relevant literature to find valuable research directions for researchers and provide new targets for osteoarthritis prevention and early treatment. ⋯ The findings from the global trend analysis indicate that research on macrophages in the treatment of osteoarthritis is gradually deepening, and the number of studies is increasing. Exosomes may become a research trend and hotspot in the future.

Observational Study
Observational study of effects of pharyngeal stimulation by carbonated solution on repetitive voluntary swallowing in humans.
In this study, we conducted observational study to examine the effects of pharyngeal stimulation by a bolus of carbonated solution on repetitive voluntary swallowing in humans. Twelve healthy participants had a fine silicone tube inserted into their pharyngeal region, through which various solutions were slowly infused (0.2 mL/minute) to stimulate the pharyngeal mucosa without activating mechanoreceptors. The solutions included 0.3M NaCl (NaCl), carbonated 0.3M NaCl (NaCl + CA), 0.3M NaCl with acetic acid, distilled water, and carbonated distilled water. ⋯ Thus, stimulation with NaCl + CA facilitated swallowing by reducing SI. Furthermore, the facilitative effects of SI were more pronounced in participants who had difficulty with repetitive voluntary swallowing. The sensation induced by carbonated solution may enhance the ability for repetitive voluntary swallowing, making it a potentially useful approach for rehabilitating patients with dysphagia.

Observational Study
Efficacy and safety of human gut-derived multi-strain probiotics in patients with irritable bowel syndrome: A prospective open-label observation study.
This study aimed to investigate the efficacy and safety of human gut-derived multi-strain probiotics in patients with irritable bowel syndrome (IBS). This was an open-label, prospective, observational study. Patients with IBS were administered human gut-derived multi-strain probiotics for 4 weeks. ⋯ Overall improvement rates in the IBS-SSS1 subscore were observed in 29.5% and 61.4% of patients at 2 and 4 weeks, respectively (P < .001). Primary and secondary outcomes were higher at 4 weeks (total IBS-SSS score, 63.6%; IBS-QOL score, 63.6%; IBS-SSS1 subscore, 61.4%) than the estimated responder rate (55%). Human gut-derived multi-strain probiotics have the potential to become an effective and safe treatment option for IBS patients.

The aim of this study was to assess the effectiveness of photo rejuvenation combined with tranexamic acid and hydroquinone cream in the treatment of complex facial pigmentation. A total of 108 patients with complex facial pigmentation between October 2019 and October 2021 were included in this retrospective study and divided into 2 groups according to the treatment that they received, with 54 cases in each group. The control group received treatment with tranexamic acid and hydroquinone cream. ⋯ Before treatment, there was no significant difference in the skin elasticity and skin water content between the observation group and control group (P > .05). After treatment, the skin elasticity and skin water content were significantly higher than that in the control group (P < .05). Photo rejuvenation combined with tranexamic acid and hydroquinone cream has a significant curative effect on patients with complex facial pigmentation, which can significantly improve skin elasticity, increase skin water content, and reduce the degree of skin lesions.
