Opportunistic Elizabethkingia miricola Infections in Intensive Care Unit, Spain.

In 2021, we identified a cluster of Elizabethkingia miricola cases in an intensive care unit in Spain. Because E. miricola is not considered a special surveillance agent in Spain, whole-genome sequencing was not performed. The bacterial source was not identified. All Elizabethkingia species should be listed as special surveillance bacteria.

Serum copper levels and risk of major adverse cardiovascular events: a systematic review and meta-analysis.

Background: Despite the fact that several studies have investigated the association between serum copper levels (S-Cu) and the risk of cardiovascular diseases, this relationship remains unclear. The aims of this study were to investigate the association between S-Cu and risk of major adverse cardiovascular events (MACE), including total stroke, ischemic stroke, hemorrhagic stroke, myocardial infarction and cardiovascular mortality, and identify potential sources of results heterogeneity. Methods: We carried out a systematic review and meta-analysis. The selection criteria were: (1) Observational studies (cohort studies, case-control studies and hybrid studies); (2) Studies containing quantitative data about the relationship between S-Cu and risk of MACE; (3) Estimating association measures; and (4) Studies written in English, French or Spanish. Overall pooled Odds ratio (pOR) and 95% confidence intervals (95% CI) of MACE for the highest vs. lowest S-Cu category were calculated using random-effects models. Results: Sixteen studies with a total of 41,322 participants were included in the meta-analysis: 10 prospective cohort studies, 5 nested case-control studies and 1 case-control study. Comparing highest vs. lowest category, high S-Cu levels were associated with total stroke (pOR: 1.49, 95% CI 1.22-1.82; I2 = 0%, p = 0.54), myocardial infarction (pOR: 1.31, 95% CI 1.17-1.46; I2 = 0.0%, p = 0.92) and cardiovascular mortality (pOR: 1.60, 95% CI 1.39-1.86; I2 = 0.0%, p = 0.54). Subgroup analysis showed that studies with a hybrid design had higher risks for cardiovascular mortality (pOR: 3.42, 95% CI 1.98-5.92) and ischemic stroke (pOR: 1.54, 95% CI 1.30-1.83). Conclusion: High S-Cu levels were associated with an increased risk of total stroke, myocardial infarction and cardiovascular mortality. Hybrid studies seems to modify the strength of the association between S-Cu and the risk of cardiovascular mortality and ischemic stroke.

Dermatological adverse reactions after vaccination with BNT162b2 in a cohort of healthcare workers.

BACKGROUND: The description of the skin reactions produced by the different vaccines against SARS-CoV-2 has focused on the symptoms reported by the general population. There are few studies with very different measurement methods focused on healthcare workers. METHODS: A longitudinal observational study was conducted on all the healthcare workers from the Hospital Universitario San Cecilio that received vaccination against COVID-19 with BNT162b2. The recruitment period was from December 2020 to September 2021. The recommended regimen was double, with a minimum interval of 21 days between doses. All dermatological reactions reported as adverse effects of the vaccine were evaluated by the Staff of the Dermatology Unit of our center. RESULTS: A total of 3969 healthcare workers of our center were followed. Only 0.7% of them reported dermatological adverse reactions. The most frequently reported reactions were morbilliform rash and COVID arm. In the multivariate analysis, the vaccination regimen (one dose) and the history of COVID-19 infection remained the main factors associated with the report of dermatological adverse reactions. CONCLUSION: The rate of dermatological adverse reactions after vaccination with BNT162b2 (Pfizer-BioNTech) is extraordinarily low. No patient required hospitalization, which supports the safety of this vaccination in a population of healthcare workers.

Factors Associated with Adverse Reactions to BNT162b2 COVID-19 Vaccine in a Cohort of 3969 Hospital Workers.

Factors associated with adverse reactions to BNT162b2 COVID-19 vaccine reported by hospital workers are unclear. Our aim was to collect all reported adverse events in a cohort of hospital workers and to analyze the factors associated with their presence. We conducted an observational longitudinal study on all hospital workers of our center who received COVID-19 vaccination from 27 December 2020 to 1 September 2021. Information on adverse events was reported telephonically and confirmed through clinical records. Chi-square and t tests as well as multivariate logistic regression models were used. Cluster analysis was designed to explore associations between reactions. A total of 3969 hospital workers were included in the sample. Of the total sample, 182 workers (4.6%) reported adverse events. The most frequent symptoms were general malaise (n = 95), fever (n = 92), arthromyalgia (n = 80), and headache (n = 47). The factors associated with adverse events in adjusted analyses were an antecedent of COVID-19 infection (OR = 2.09, 95% CI: 1.47-2.98), female sex (OR = 1.51, 95% CI: 1.03-2.20), and professional category (OR for physicians = 0.41, 95% CI: 0.21-0.80). We report a low frequency of adverse events in hospital workers after COVID-19 vaccination and no severe reaction. Men and physicians underreported their symptoms. These data should guide future strategies for recording adverse events and future research on COVID-19 vaccination safety.
