Update: Characteristics of Patients in a National Outbreak of E-cigarette, or Vaping, Product Use-Associated Lung Injuries - United States, October 2019.

CDC, the Food and Drug Administration, state and local health departments, and other public health and clinical stakeholders are investigating a national outbreak of electronic-cigarette (e-cigarette), or vaping, product use-associated lung injury (EVALI) (1). As of October 22, 2019, 49 states, the District of Columbia (DC), and the U.S. Virgin Islands have reported 1,604 cases of EVALI to CDC, including 34 (2.1%) EVALI-associated deaths in 24 states. Based on data collected as of October 15, 2019, this report updates data on patient characteristics and substances used in e-cigarette, or vaping, products (2) and describes characteristics of EVALI-associated deaths. The median age of EVALI patients who survived was 23 years, and the median age of EVALI patients who died was 45 years. Among 867 (54%) EVALI patients with available data on use of specific e-cigarette, or vaping, products in the 3 months preceding symptom onset, 86% reported any use of tetrahydrocannabinol (THC)-containing products, 64% reported any use of nicotine-containing products, and 52% reported use of both. Exclusive use of THC-containing products was reported by 34% of patients and exclusive use of nicotine-containing products by 11%, and for 2% of patients, no use of either THC- or nicotine-containing products was reported. Among 19 EVALI patients who died and for whom substance use data were available, 84% reported any use of THC-containing products, including 63% who reported exclusive use of THC-containing products; 37% reported any use of nicotine-containing products, including 16% who reported exclusive use of nicotine-containing products. To date, no single compound or ingredient used in e-cigarette, or vaping, products has emerged as the cause of EVALI, and there might be more than one cause. Because most patients reported using THC-containing products before symptom onset, CDC recommends that persons should not use e-cigarette, or vaping, products that contain THC. In addition, because the specific compound or ingredient causing lung injury is not yet known, and while the investigation continues, persons should consider refraining from the use of all e-cigarette, or vaping, products.

OBJECTIVE: Describe the distribution of the nursing workforce in countries of the Region of the Americas and the relation between the number of human resources in nursing and maternal mortality ratios. METHODS: Descriptive and exploratory analysis of 27 countries of the Region. The variables in the study were the proportion of health professionals per country and subregion; professional category; and nurse-to-physician ratio. The maternal mortality ratio was used as an overall indicator of the health of the population to analyze its relationship to the number of nurses. Frequency distribution and density of human resources in nursing were analyzed per country and subregion. RESULTS: The distribution of nursing personnel was heterogeneous. Some countries had more than 80 nurses per 10 000 population and others had fewer than five professionals per 10 000 population. In 34.1% of the countries, the nurse-to-physician ratio was less than 1. Differences in the distribution of nursing personnel were observed between regions and subregions, and within countries. CONCLUSIONS: In several countries, the number of nurses per capita was less than expected. The majority of the countries showed a significantly lower proportion of licensed nurses with respect to technical and auxiliary personnel. It is necessary to implement initiatives to increase the number of licensed nurses throughout the Region.

OBJETIVO: Descrever a distribuição de pessoal de enfermagem nos países da Região das Américas e estabelecer a relação do número de profissionais de enfermagem com o índice de mortalidade materna. MÉTODOS: Estudo descritivo e exploratório conduzido em 27 países da Região das Américas. As variáveis estudadas foram proporção de profissionais por país e subregião, categoria profissional e relação enfermeiro-médico. O índice de mortalidade materna, por ser um indicador geral de saúde da população, foi usado para analisar a relação com o aspecto quantitativo de enfermeiros. Foram analisadas a distribuição de frequências e a densidade dos profissionais de enfermagem por país e sub-região. RESULTADOS: Verificou-se uma distribuição heterogênea do pessoal de enfermagem, com alguns países com mais de 80 enfermeiros por 10 mil habitantes e outros com menos de cinco profissionais por 10 mil habitantes. Observou-se uma relação enfermeiro-médico inferior a um em 34,1% dos países. Houve diferenças na distribuição de pessoal de enfermagem por região, sub-região e dentro do próprio país. CONCLUSÕES: Em vários países da Região das Américas, o número de enfermeiros por habitantes é menor que o esperado. A maioria dos países tem uma defasagem considerável na razão do número de enfermeiros licenciados em relação ao pessoal de enfermagem técnico e auxiliar. É necessário implementar iniciativas para aumentar o número de enfermeiros licenciados em toda a Região.
