Background and Aims Initial reports on US COVID-19 showed different outcomes in different races. In this study we use a diverse large cohort of hospitalized COVID-19 patients to determine predictors of mortality. Methods We analyzed data from hospitalized COVID-19 patients (n = 5852) between March 2020- August 2020 from 8 hospitals across the US. Demographics, comorbidities, symptoms and laboratory data were collected. Results The cohort contained 3,662 (61.7%) African Americans (AA), 286 (5%) American Latinx (LAT), 1,407 (23.9%), European Americans (EA), and 93 (1.5%) American Asians (AS). Survivors and non-survivors mean ages in years were 58 and 68 for AA, 58 and 77 for EA, 44 and 61 for LAT, and 51 and 63 for AS. Mortality rates for AA, LAT, EA and AS were 14.8, 7.3, 16.3 and 2.2%. Mortality increased among patients with the following characteristics: age, male gender, New York region, cardiac disease, COPD, diabetes mellitus, hypertension, history of cancer, immunosuppression, elevated lymphocytes, CRP, ferritin, D-Dimer, creatinine, troponin, and procalcitonin. Use of mechanical ventilation (p = 0.001), shortness of breath (SOB) (p < 0.01), fatigue (p = 0.04), diarrhea (p = 0.02), and increased AST (p < 0.01), significantly correlated with death in multivariate analysis. Male sex and EA and AA race/ethnicity had higher frequency of death. Diarrhea was among the most common GI symptom amongst AAs (6.8%). When adjusting for comorbidities, significant variables among the demographics of study population were age (over 45 years old), male sex, EA, and patients hospitalized in New York. When adjusting for disease severity, significant variables were age over 65 years old, male sex, EA as well as having SOB, elevated CRP and D-dimer. Glucocorticoid usage was associated with an increased risk of COVID-19 death in our cohort. Conclusion Among this large cohort of hospitalized COVID-19 patients enriched for African Americans, our study findings may reflect the extent of systemic organ involvement by SARS-CoV-2 and subsequent progression to multi-system organ failure. High mortality in AA in comparison with LAT is likely related to high frequency of comorbidities and older age among AA. Glucocorticoids should be used carefully considering the poor outcomes associated with it. Special focus in treating patients with elevated liver enzymes and other inflammatory biomarkers such as CRP, troponin, ferritin, procalcitonin, and D-dimer are required to prevent poor outcomes.

PurposeThe purpose of this paper is to assess the impact of professional training and development for librarians/library staff in the southwest, Nigeria; especially the Federal University of OyeEkiti, Nigeria. Thus, this study intends to assess the impact of staff professional development and training on the job performance of library staff in the Federal University Oye Ekiti, Nigeria.Design/methodology/approachThe descriptive survey research design was used in carrying out this study. The population of study cuts across all library staff/attendants in the Federal University Oye Ekiti departmental, faculty and the university libraries. The purposive sampling technique was used in selecting the sample for the study (77 library staff). Research instruments, developed by the researchers, Staff Development Programme Questionnaire (r = 0.79), Staff performance Questionnaire (r = 0.81), Challenges of Staff Professional Development and Training Questionnaire (r = 0.82), were used for data collection. The data were analysed using descriptive statistics (frequency counts and percentages, mean and standard deviation) and inference statistics (correlation and one-way ANOVA) at a 5% level of significance.FindingsResults revealed that the level of the job performance of library staff in Federal University Oye-Ekiti (FUOYE) is high; there is a positive and statistically significant relationship between the professional development of library staff and their performance in the job; professional development and training of library staff significantly impact their job performance; orientation, in-house training, seminars, on-the-job training and instructor-led training.Research limitations/implicationsThe study was limited to the university libraries in the Federal University Oye Ekiti, Nigeria. The variables used in this study were restricted to training and development of library staff and job performance of librarians in FUOYE, and professional development programmes available for FUOYE librarians.Practical implicationsOther forms of professional development programmes such as Distance Educational Programmes, Conferences/Workshops, Study visits, Formal professional library education and TETFUND Programmes should be made available for university library staff. Universities should always organise staff professional development programmes; since it enhances the job performance of library staff.Originality/valueThis article is original and has not been published elsewhere.
