Abstract
Epidemiological and clinical data of patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant (BA.2) admitted to three designated hospitals in Quanzhou City, Fujian Province, China, were collected and analyzed. Overall, 2,541 patients infected with BA.2, comprising 1,060 asymptomatic, 1,287 mild, and 194 moderate infections, were enrolled. The percentage of moderate infections was higher in patients aged ≥ 60 years than in those aged < 18 years and 18-59 years. The median hospitalization duration was 17 days. Among the 2,541 patients, 43.52% had a clear history of close contact. The vaccination rate was 87.92%, and the percentage of asymptomatic infections was higher in vaccinated than in unvaccinated patients. Moreover, patients with underlying diseases, including hypertension and diabetes mellitus, had more moderate infections than those without underlying diseases. The three most common clinical manifestations were fever, dry cough, and sore throat. The albumin-to-globulin (A/G) ratio and lymphocyte count decreased in cases with mild and moderate infections, while procalcitonin, erythrocyte sedimentation rate, interleukin-6, D-dimer, and C4 levels increased. Advanced age, non-vaccination, and underlying comorbid diseases were high-risk factors for disease progression in patients. However, dynamic monitoring of blood routine parameters, A/G ratio, and inflammatory indicators facilitated the prediction of disease progression.

[PMID: 36619417 PMCID: PMC9813729 DOI: 10.1016/j.heliyon.2022.e12349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 11/14/2022] [Accepted: 12/07/2022] [Indexed: 12/23/2022] Open
Abstract
Despite availability of instruments for measuring attitudes towards mask use, the psychometric properties of many available instruments are not adequately established which limits their research usefulness across contexts. In three studies, we developed the Attitudes Towards Face Mask Use Scale (ATFMUS) in three phases: item generation, scale development, and scale evaluation. Phase one and two were addressed in study 1 while phase three was addressed in studies 2 and 3. In Study 1, a combined online and pen-and-paper sample of 174 (78% university students) completed a questionnaire with 19 items regarding attitudes towards face mask use derived from theory, previous research, and experience. Responses were subjected to item reduction analysis, exploratory factor analysis and reliability analysis. In Study 2, a student sample of 674 (70.5% high school) completed the new scale together with measures of COVID-19 related anxiety and obsession, personality, affect, social media use, and social desirability. Data from the ATFMUS were analyzed using confirmatory factor analysis and pertinent revisions done. The ATFMUS was then validated using correlation analyses, measurement invariance analyses, and known-group comparisons. In study 3, two samples of university students from Ghana (n = 242) and Kenya (n = 199) were involved in testing the cross-country invariance of the ATFMUS. The results reveal that the 5-item ATFMUS is a reliable and valid scale for assessing attitudes towards face mask use. Invariance analysis revealed that the ATFMUS is fair to use across participants of different age, level of education, and countries. The scale is also sensitive to participants' actual use of face masks as well as their beliefs about COVID-19 and efficacy of the facemasks. This study offers a foundation for further psychometric evaluation of the ATFMUS.

Clinical characteristics of patients infected with novel coronavirus wild strain, Delta variant strain and Omicron variant strain in Quanzhou: A real‑world study. Exp Ther Med 2022; 25:62. [PMID: 36588806 PMCID: PMC9780511 DOI: 10.3892/etm.2022.11761] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 08/12/2022] [Indexed: 12/13/2022] Open
Abstract
This study aimed to investigate the clinical features of patients infected with novel coronavirus wild strains, Delta variant strains and Omicron variant strains to provide a reference for early clinical diagnosis and prognostic assessment. The demographic, clinical symptoms and ancillary examination data of 47 patients with novel coronavirus wild type strain infection, 18 with Delta variant infection and 20 with Omicron variant infection admitted to the First Hospital of Quanzhou affiliated with Fujian Medical University were collected and analyzed. The novel coronavirus wild strain and Delta strain were the predominant clinical types; patients infected with the Omicron strain were mainly asymptomatic. Fever and fatigue were the main clinical manifestations in the wild strain and Delta strain groups, whereas dry cough, nasal congestion, sore throat and fever were common clinical manifestations in the Omicron strain group. The Delta strain and Omicron variant groups had fewer comorbidities than the wild-type strain group, but no significant reduction was observed in the negative conversion time of nucleic acids. Significant differences were found in the neutrophil count/lymphocyte count ratio, lymphocyte count, eosinophil count, red blood cell count, hemoglobin level, erythrocyte sedimentation rate, C-reactive protein, prothrombin time, international normalized ratio and plasma D-dimer, PH, PaO2, lactic acid and albumin levels among the three groups. Patients infected with the Omicron strain in Quanzhou presented with mild symptoms of the upper respiratory tract as the primary clinical manifestation and had few comorbidities and a good prognosis; however, the negative conversion time of the new coronavirus nucleic acid was still considerably long.
