Objective To determine the independent influencing factors of intraoperative choking during painless gastrointestinal endoscopy (PGIE) after coronavirus disease 2019 (COVID-19). Methods The data of patients undergoing PGIE with COVID-19 in Northern Jiangsu People’s Hospital between December 2022 and April 2023 were retrospectively collected. Multiple logistic regression analysis was used to screen the influencing factors of intraoperative coughing events that occurred during the diagnosis and treatment process. Results A total of 948 patients were included, with 93 (9.8%) cases of choking. The results of the multiple logistic regression analysis showed that smoking and unresolved cough were independent risk factors for coughing (P<0.05), while colonoscopy and infection duration beyond 14 days between diagnosis and treatment were independent protective factors for coughing (P<0.05). ConclusionsWhen patients with COVID-19 undergoing PGIE, special attention should be paid to high-risk groups such as smoking and unresolved cough. It is necessary to strengthen intraoperative monitoring and implementation of prevention and control measures to reduce the incidence of coughing and improve the safety of diagnosis and treatment for patients.
ObjectiveTo systematically review the economic evaluation research of anti-novel coronavirus infection drugs at home and abroad, so as to promote clinical rational drug use. MethodsThe PubMed, Cochrane Library, EMbase, Web of Science, INAHTA, SinoMed, WanFang Data, and CNKI databases were systematically searched from January 1, 2020 to March 25, 2023, to collect economic evaluation studies related to anti-novel coronavirus infection drugs. ResultsA total of 22 articles were included, among which 11 studies were conducted from the perspective of health system, and most of the studies performed cost estimation on direct medical costs. The overall compliance rate of the included studies ranged from 42% to 70%, with deficiencies in model setting, incomplete uncertainty analysis, and lack of stakeholder participation. The results showed that immunotherapy drugs (Dexamethasone, Tocilizumab), neutralizing antibody (REGEN-COV antibody), small molecule drugs (Baricitinib, Nirmatrelvir/Ritonavir, Molnupiravir, Favipiravir) and statin were cost-effective. There was some variation in the results of the economic evaluation of Remdesivir. ConclusionAt present, there are few studies on the economic evaluation of drug interventions in COVID-19. Existing studies have pointed out that most drug interventions are cost-effective. It is suggested that more standardized pharmacoeconomic evaluation studies based on the actual situation of China epidemic should be carried out in the future.
After the promulgation of the “Ten New Measures” for coronavirus disease 2019 (COVID-19) pandemic, the Nursing Department of West China Hospital of Sichuan University promptly analyzed the development and changes of the epidemic situation and the key and difficult points of nursing manpower emergency management, and constructed a “1+2+4+X” nursing manpower emergency management model for COVID-19 patients, including establishing a dedicated management team, assessing manpower needs, constructing a nursing manpower management model, on-site and online training, and dynamic monitoring and adjustment. From December 7th, 2022 to February 1st, 2023, the Nursing Department mobilized a total of 693 nurses, covering 4 temporary intensive care units and 30 temporary general wards. The hospital-wide qualification rate of airway humidification management for patients in temporary general wards was 94.9%, the qualification rate of artificial airway fixation was 97.9%, and the compliance of bed head elevation was 100.0%. The “1+2+4+X” nursing manpower emergency management model constructed is helpful for the reasonable scheduling of nursing manpower during the epidemic period and provides a reference for the emergency deployment of nursing manpower for the treatment of infectious disease epidemics in large medical institutions in the future.
Most patients with coronavirus disease 2019 (COVID-19) have a good prognosis, but a certain proportion of the elderly and people with underlying diseases are still prone to develop into severe and critical COVID-19. Kidney is one of the common target organs of COVID-19. Acute kidney injury (AKI) is a common complication of severe COVID-19 patients, especially critical COVID-19 patients admitted to intensive care units. AKI associated with COVID-19 is also an independent risk factor for poor prognosis in patients. This article mainly focuses on the epidemiological data, possible pathogenesis, diagnostic criteria, and prevention and treatment based on the 5R principle of AKI associated with COVID-19. It summarizes the existing evidence to explore standardized management strategies for AKI associated with COVID-19.
ObjectiveTo observe the clinical and multimodal imaging features of eyes with acute macular neuroretinopathy (AMN) associated with the coronavirus disease 2019 (COVID-19). MethodsA retrospective study. From December 20, 2022 to January 17, 2023, a total of 29 patients (58 eyes) with COVID-19-associated AMN admitted to Department of Ophthalmology of Eye and ENT Hospital, Shanghai Medical College were included in the study. All the affected eyes underwent the best corrected visual acuity, color fundus photography, infrared fundus photography (IR), short-wavelength autofluorescence (SW-AF), near-infrared autofluorescence (NIL-AF), optical coherence tomography (OCT), and OCT angiography (OCTA). All patients were administered microcirculation-improving oral medication with 12 cases receiving adjunctive low-dose corticosteroid therapy. Follow-ups were conducted 1 to 3 months after the initial diagnosis, with a total of 19 cases (38 eyes) completing the one-month follow-up. ResultsOut of the 29 cases, there were 9 males (18 eyes) and 20 females (40 eyes), all of whom experienced bilateral eye involvement. The age of the patients ranged from 12 to 47 years, with an average age of (29.9±9.5) years. The time from the onset of fever to the appearance of ocular symptoms was (2.52±2.01) days. Among the 58 affected eyes, there were 5 cases with retinal cotton wool spots, 2 cases with optic disc edema, and 1 case with parafoveal branch retinal vein occlusion. All affected eyes exhibited deep reddish-brown macular dark spots. IR revealed wedge-shaped, wedge-like, or "petaloid-like" dark areas involving the fovea and parafovea. SW-AF examination showed no obvious abnormality in 39 eyes. Weak autofluorescence dark area were consistent with IR in 19 eyes. NIR-AF examination showed spot-like or flaky self-fluorescent dark areas. OCT examination showed strong reflex lesions spreading vertically upward from the retinal pigment epithelium (RPE) layer in the macular area in the acute stage, showing typical "bean seedling" sign. OCTA revealed reduced blood flow density in the deep capillary plexus (DCP) of 50 eyes. En-face OCT displayed lesion areas that corresponded to the dark areas seen in IR. One month after the initial diagnosis, the condition improved in 18 eyes (47.4%, 18/38). Among the 5 eyes with cotton wool spots, regression of these spots was accompanied by loss of nerve fiber layer in 4 eyes. In cases with optic disc edema, the edema subsided. The "bean sprout" sign disappeared in all affected eyes, and the lesions became localized. The ellipsoid zone and/or interdigitation zone in the lesion areas were discontinuous. ConclusionsCOVID-19-related AMN is characterized by distinctive features. IR fundus reveals wedge-shaped, wedge-like, or petaloid dark areas involving the fovea and parafovea. OCT displays strongly reflective lesions with vertical spread above the RPE. OCTA shows reduced blood flow density in the DCP of the retina.
ObjectiveTo construct a lentiviral vector carrying rat sirt1 gene and observe the expression of sirt1 in retinal ganglion cell (RGC) of rat. MethodsRat sirt1 cDNA was inserted into pLV5 vector. After identification by sequencing analysis and PCR, the recombinant sirt1expressinglentivirus vector was packaged by cotransfecting 293T cells with packaged plasmid.Then pLV5-sirt1 was used to infect the cultured Sprague-Dawley rat RGC cell in vitro.The expressions of sirt1 protein and mRNA in infected rat RGC were detected by quantitative real-time PCR and Western blot. ResultsThe sirt1 expression vector pLV5 was successful constructed and sequence was proved to be correct. The expression of sirt1 protein and mRNA in RGC was significantly increased than that in cells infected with control lentiviruses(P < 0.05). ConclusionWe have successful constructed a sirt1 expression lentivirus vector pLV5-sirt1 and it can increase the expression of sirt1 protein and mRNA in the rat retinal ganglion cells.
ObjectiveTo explore the postoperative characteristics and management experience of patients with coronavirus disease 2019 (COVID-19) undergoing cardiac and vascular surgery. MethodsFrom December 7, 2022 to January 5, 2023, the patients with COVID-19 who were admitted to Cardiovascular Hospital Affiliated to Kunming Medical University and underwent cardiac and vascular surgery were selected. The clinical history, surgical information, postoperative recovery process and treatment plan were analyzed retrospectively. ResultsThere were 18 patients in this group, including 11 (61.1%) males and 7 (38.9%) females, with an average age of 58.1±10.9 years. There were 7 patients of hypertension, 5 patients of diabetes, 3 patients of respiratory diseases, and 2 patient of chronic renal insufficiency. There were 5 (27.8%) patients receiving emergency operations and 13 (72.2%) elective operations. All the 18 patients underwent cardiac and vascular surgery in the period of COVID-19, and the time between the last positive nucleic acid test and the surgery was 1.50 (1.00, 6.25) days. There were 8 patients of pulmonary imaging changes, including 3 patients with chest patch shadow, 3 patients with thickened and disordered lung markings, and 2 patients with exudative changes before operation. Antiviral therapy was not adopted in all patients before operation. Three patients were complicated with viral pneumonia after operation, including 2 patients with high risk factors before operation, who developed into severe pneumonia after operation, and underwent tracheotomy. One patient with thrombus recovered after anticoagulation treatment. Another patient of mild pneumonia recovered after antiviral treatment. The other 15 patients recovered well without major complications. There was no operation-related death in the whole group. One patient died after surgery, with a mortality rate of 5.6%. Conclusion Patients with COVID-19 are at high risk of cardiac and vascular surgery, and patients with high-risk factors may rapidly progress to severe pneumonia. Patients with preoperative lung imaging changes or other basic visceral diseases should consider delaying the operation. Early antiviral combined with immunomodulation treatment for emergency surgery patients may help improve the prognosis.
