ABSTRACT

Measles is an extremely contagious viral disease. Even though a safe vaccine exists for this disease, it remains one of the leading causes of mortality and morbidity in infants and young children. We aimed to create a retrospective descriptive study in which to analyze the evolution of the measles epidemic at the European level. The documentation was carried out using European Centre for Disease Prevention and Control (ECDC) and World Health Organization (WHO) statistics. At the same time, we present the epidemic's evolution in Romania, using data provided by the Romanian National Institute of Public Health and Ministry of Health. European statistical data indicate a high number of patients diagnosed with measles both among children and adults. All European countries benefit from the measles vaccination in the form of the measles-mumps-rubella (MMR) trivaccine included in their National Vaccination Programme. The vaccination schedule varies from country to country. In the vaccination scheme, most European countries include two doses of the MMR vaccine among the pediatric population. Romania registered a limited number of cases of measles between 1980 and 2015 following the introduction of the measles vaccination in the National Vaccination Programme. Since 2005, the Romanian vaccination schedule includes two doses of MMR trivaccine, administered at 12 months and at 6-7 years. After 2015, as a result of a significant decrease in the number of vaccinated children, Romania is facing a major increase in the cases of measles. Consecutively, a measles epidemic was declared in 2016 and an additional dose of mandatory MMR trivaccine was introduced at the age of 9 months. After 4 years of this schedule of administration, starting with August 2020, the additional dose of MMR administered during infancy has been discontinued. We propose an analysis of the factors that influenced the downward evolution of the measles epidemic in Romania at the beginning of the third millennium. Issues related to the limitation of interpersonal contact in the context of the social distancing imposed by the Sars-CoV-2 virus pandemic are discussed. We consider necessary a detailed documentation of the percentage of new disease cases that will appear in the pediatric population in the near future, in the context of the resumption of daily activity after the reopening of nurseries, kindergartens and schools.

ABSTRACT

The purpose of this study was to identify the predictors of burnout in healthcare workers during the COVID-19 pandemic. Data were collected from March to June in 2020, during the COVID-19 pandemic, from employees of two Romanian hospitals. Five hundred and twenty-three healthcare workers completed a series of questionnaires that measured burnout, job demands, job resources, and personal resources. Among the respondents, 14.5% had a clinical level of exhaustion (the central component of burnout). Three job demands (work-family conflict, lack of preparedness/scope of practice, emotional demands), three job resources (training, professional development, and continuing education; supervision, recognition, and feedback; autonomy and control), and one personal resource (self-efficacy) were significant predictors of burnout, explaining together 37% of the variance in healthcare workers' burnout. Based on our results, psychological interventions during the COVID-19 pandemic for healthcare employees should focus primarily on these demands and resources.

ABSTRACT

Cardiac fibroblasts play a main role in the physiological turnover of the extracellular matrix, as well as its pathological remodeling. A study was performed on a batch of 23 cases who died of various cardiac complications secondary to scarring myocardial infarctions. The aim of the study was to assess the fibroblast involvement in cardiac repair under ischemic conditions after myocardial infarction. Tissue myocardial samples from the left ventricle were taken from these cases for microscopy examination, in order to investigate the type and degree of fibrosis as well as the presence of cardiac interstitial fibroblasts. Multiple series of histological sections were also performed and examined, along with immunohistochemical analysis. The fibroblasts were diffusely distributed in the interstitium among the residual cardiomyocytes, showing variable expression of vimentin and smooth muscle actin. During cardiac remodeling, there was a successive interstitial deposition, first of reticulin fibers and then of collagen fibers, leading to interstitial fibrosis and myocardial replacement. There was a correlation between vimentin and smooth muscle actin expression and collagen deposition. Fibrosis with cardiac remodeling is based on maintaining proliferation capacity of the fibroblast and its capacity of protein synthesis in the extracellular matrix. Under hypoxic ischemic conditions, followed by myocardial infarction, the fibroblast switches phenotype and transdifferentiate into myofibroblast, contributing to the healing by secreting extracellular matrix proteins and collagen deposition, with subsequent cardiac remodeling and regulation of the micro-environment metabolism.
