Risk of Burnout among Emergency Department Staff as a Result of Violence and Aggression from Patients and Their Relatives.

Emergency department staff are often affected by incidents of violence. The aim of the study was to generate data on the frequency of violence by patients and accompanying relatives and the correlation between experienced aggression, a possible risk of burnout and a high sense of stress. Additionally, the buffering effect of good preventive preparation of care staff by the facility on aggressive visitors and patients was examined. In this cross-sectional study, members of the German Society for Interdisciplinary Emergency and Acute Medicine were surveyed. The investigation of risk factors, particularly experiences of verbal and physical violence, as well as exhaustion and stress, was carried out using ordinal regression models. A total of 349 staff from German emergency departments took part in the survey, 87% of whom had experienced physical violence by patients and 64% by relatives. 97% had been confronted with verbal violence by patients and 94% by relatives. Violence by relatives had a negative effect on perceived stress. High resilience or effective preparation of employees for potential attacks was shown to have a protective effect with regard to the burnout risk and perceived stress. Therefore, management staff play a major role in preventing violence and its impact on employees.

Eye-Catching Microbes-Polyphasic Analysis of the Microbiota on Microscope Oculars Verifies Their Role as Fomites.

Microscopes are used in virtually every biological and medical laboratory. Previous cultivation-based studies have suggested that direct contact with microscope eyepieces increases the risk of eye infections. To obtain a deeper insight into the microbiota on oculars, we analysed 10 recently used university microscopes. Their left oculars were used for a cultivation-based approach, while the right oculars served for massive gene sequencing. After cleaning with isopropyl alcohol, the oculars were re-sampled and analysed again. All oculars were found to be contaminated with bacteria, with a maximum load of 1.7 × 103 CFU cm-2. MALDI Biotyping revealed mainly Cutibacterium (68%), Staphylococcus (14%) and Brevibacterium (10%), with the most abundant species being Cutibacterium acnes (13%) and Staphylococcus capitis (6%). Cleaning reduced the microbial load by up to 2 log scales. Within 10 uncleaned and 5 cleaned samples, 1480 ASVs were assigned to 10 phyla and 262 genera. The dominant genera before cleaning were Cutibacterium (78%), Paracoccus (13%), Pseudomonas (2%) and Acinetobacter (1%). The bacteriota composition on the cleaned oculars was similar; however, it probably largely represented dead bacteria. In summary, used oculars were significantly contaminated with skin and environmental bacteria, including potential pathogens. Regular cleaning is highly recommended to prevent eye and skin infections.

The significance of entry routes as point and non-point sources of pesticides in small streams.

In an agricultural catchment area in Germany we analyzed water samples from five entry routes for 2 insecticides. 5 fungicides and 13 herbicides. The sewage plant outlet and the emergency overflow of a sewage sewer contained only herbicides. In each farmyard runoff we found on average 24 g pesticides during application period, presumably caused by cleaning the spraying equipment. In comparison, the field runoff and the rainwater sewer contained less load, but also insecticides, fungicides and herbicides. The sewage plant caused 65.9% of the total herbicide load, the sewage sewer 19.8% and the farmyard runoff 12.8%. The farmyards also caused 83.7% of total insecticide and 83.8% of fungicide load. The total load of all entry routes is correlated with the amount of pesticides applied in the catchment area and the Ko/w value for each pesticide (mult. regress. r2: 0.82; p<0.0001; n = 14). In stream A the sewage plant caused a slight but continuous contamination by herbicides with 82% of the total load found during low-water phases. In comparison, stream B had only farmyard runoff and non-point sources, which caused high peaks of herbicide and a contamination by insecticides. Consequently, high-water phases generated 70% of the total pesticide load.
