Non-enveloped viruses are particularly resistant to disinfectants, so it is necessary to use disinfectants with proven virucidal activity in order to prevent and control the spread of viral infections. However, a test such as EN 1500, which uses an internal standard as the reference treatment for determining the bactericidal efficacy of hand rubs, is still lacking. This study aimed to establish a European standard for testing the in-vivo efficacy of hand rubs against non-enveloped viruses.
METHODS
The concentration and mode of application of ethanol as the reference were determined, and compared with the efficacies of two commonly used hand rubs. The hands of volunteers were contaminated with murine norovirus strain S99.
RESULTS
70% wt/wt ethanol (2 x 3~mL in 2 x 30~s) was used as the internal reference treatment. The commercial ethanol-based hand rub was able to reduce the titre of murine norovirus significantly in 30~s, whereas a hand rub based on ethanol and propan-2-ol was significantly less effective compared with the reference.
CONCLUSION
This study established a possible standard for testing the in-vivo efficacy of hand rubs against non-enveloped viruses using murine norovirus, a low contamination volume technique and ethanol as the internal reference. These findings need to be confirmed in European ring trials.},

The approval of ethanol by the Biocidal Products Regulation has been under evaluation since 2007. This follows concern over alcohol uptake from ethanol-based hand rubs (EBHR). If ethanol is classified as carcinogenic, mutagenic, or reprotoxic by the European Chemicals Agency (ECHA), then this would affect infection prevention and control practices.
AIM
A review was performed to prove that ethanol is toxicological uncritical and indispensable for hand antisepsis because of its unique activity against non-enveloped viruses and thus the resulting lack of alternatives. Therefore, the following main points are analyzed: The effectiveness of ethanol in hand hygiene, the evidence of ethanol at blood/tissue levels through hand hygiene in healthcare, and the evidence of toxicity of different blood/tissue ethanol levels and the non-comparability with alcoholic consumption and industrial exposure.
RESULTS
EBHR are essential for preventing infections caused by non-enveloped viruses, especially in healthcare, nursing homes, food industry and other areas. Propanols are effective against enveloped viruses as opposed to non-enveloped viruses but there are no other alternatives for virucidal hand antisepsis. Long-term ingestion of ethanol in the form of alcoholic beverages can cause tumours. However, lifetime exposure to ethanol from occupational exposure textless 500~ppm does not significantly contribute to the cancer risk. Mutagenic effects were observed only at doses within the toxic range in animal studies. While reprotoxicity is linked with abuse of alcoholic beverages, there is no epidemiological evidence for this from EBHR use in healthcare facilities or from products containing ethanol in non-healthcare settings.
CONCLUSION
The body of evidence shows EBHRs have strong efficacy in killing non-enveloped viruses, whereas 1-propanol and 2-propanol do not kill non-enveloped viruses, that pose significant risk of infection. Ethanol absorbed through the skin during hand hygiene is similar to consumption of beverages with hidden ethanol content (textless 0.5% v/v), such as apple juice or kefir. There is no risk of carcinogenicity, mutagenicity or reprotoxicity from repeated use of EBHR. Hence, the WHO Task Force strongly recommend retaining ethanol as an essential constituent in hand rubs for healthcare.},

The reliable detection of T cell response to COVID-19 or COVID-19 vaccination is important for individual patient care and for monitoring the immune response e.g. in COVID-19 vaccine trials in a standardized fashion.
OBJECTIVES AND STUDY DESIGN
We used blood samples from health care workers (HCW) with or without history of COVID-19 to define test accuracy of a novel interferon-textgreekg release assay (IGRA). For a real-life performance evaluation, we analysed interferon-textgreekg response to complete COVID-19 vaccination in HCW receiving homologous or heterologous vaccination regimens and in patients receiving immunosuppressive or immune modulating therapies.
RESULTS
The assay had a specificity of 100%. Sensitivity of the IGRA to detect past infection was 72.2% after infection more than 5 months ago and 93.8% after COVID-19 up to 5 months ago. Quantitative results showed significant differences between first and second vaccine dose, but no difference between homologous and heterologous vaccination regimen. Immunocompromised patients often had no immune response or isolated T cell or antibody response to complete vaccination.
CONCLUSIONS
The novel IGRA proved to be a highly specific tool to detect SARS-CoV-2 specific T cell response to COVID-19 as well as COVID-19 vaccination, with sensitivity getting lower over time. In perspective, it may serve as a standardized tool in COVID-19 vaccine trials and in clinical care of immunosuppressed patients.},

Thus, chemical disinfectants claiming textquotedblvirucidal activity against enveloped virusestextquotedbl based on EN 14476 or DVV/RKI guideline will be an effective choice to target enveloped SARS-CoV-2 as a preventive measure.

In this study we set out to examine the efficacy of the hyperimmunoglobulin (HIG treatment in women with a recent primary CMV infection up to 14 weeks' gestation.
METHODS
Ongoing observational study at the prenatal medicine departments of Tuebingen, Bonn, Cologne and Erlangen, Germany as well as the laboratory Prof. Gisela Enders and Colleagues in Stuttgart, Germany and the Institute for Medical Virology at the University of Tuebingen. Enrollment criteria were the presence of confirmed, very recent primary CMV infection in the first trimester and a gestational age at first HIG administration of $\leq$ 14 weeks. The following inclusion criteria indicated a recent primary infection: low anti-IgG levels, low anti-CMV-IgG avidity in the presence of a positive CMV IgM test and no or just seroconversion anti-gB2-IgG-reactivity. The HIG administration (Cytotect CPcircledR, Biotest, Germany) was started as soon as possible within few days after the first visit in the four units. HIG was administered at 200 IU per kilogram bodyweight intravenously and repeated every two weeks until about 18 weeks' gestation. Maternal-fetal transmission at the time of amniocentesis was considered as relevant primary outcome measure. Multivariate logistic regression analysis was used to determine significant covariates that could be used for the prediction of maternal-fetal transmission.
RESULTS
149 pregnant women and 153 fetuses were treated. Median maternal age and weight was 32.0 years and 65.0 kg, respectively. Median gestational age at the time of the first referral to one of the four centers was 9.4 weeks. Median anti-CMV-IgG levels, the anti-CMV-IgM index and the CMV IgG avidity was 5.7 U/ml, 2.5, and 22.3%, respectively. Treatment with HIG started at a median gestational age of 10.6 weeks and ended at 17.9 weeks. Within this time frame, HIGs were administered on average 4 times. Amniocentesis was carried out at a median gestational age of 20.4 weeks. In 143 (93.6%) of the 153 cases, the fetus was not infected. Maternal-fetal transmission occurred in 10 cases (6.5%, [95% CI 3.2 - 11.7]). In the uni- and multivariate logistic regression analysis, only the level of the anti-IgM index was significantly associated with maternal-fetal transmission at the time of the amniocentesis. However, only four (40.0%) of the 10 cases with maternal-fetal transmission had an anti-IgM level above 11.4 which corresponds to the 95th centile of the pregnancies without transmission.
CONCLUSION
HIG is a treatment option to prevent maternal-fetal transmission in a case of a primary CMV infection. However, treatment is only beneficial in women with a very recent primary infection in the first trimester or during the periconceptional period, a timely start and an appropriate treatment interval.

abstract = {BACKGROUND
Dosing recommendations for the treatment of pregnancy-acquired toxoplasmosis are empirical and widely based on experimental data. There are no pharmacological data on pregnant women with acute Toxoplasma gondii infection under treatment with pyrimethamine (PY) and sulfadiazine (SA) and our study intends to tighten this gap.
METHODS
In this retrospective case-control study, we included 89 pregnant women with primary Toxoplasma infection (PT) treated with PY (50~mg first dose, then 25~mg/day), SA (50~mg/kg of body weight/day), and folinic acid (10-15~mg per week). These were compared to a group of 17 women with acute ocular toxoplasmosis (OT) treated with an initial PY dose of 75~mg, thereafter 25~mg twice a day but on the same SA and folinic acid regimen. The exact interval between drug intake and blood sampling and co-medication had not been recorded. Plasma levels of PY and SA were determined 14 $pm$ 4~days after treatment initiation using liquid chromatography-mass spectrometry and compared using the Mann-Whitney U test at a p textless 0.05 level.
RESULTS
In 23 PT patients (26%), SA levels were below 20~mg/l. Fifteen of these 23 patients (17% of all patients) in parallel presented with PY levels below 700~µg/l. Both drug concentrations differed remarkably between individuals and groups (PY: PT median 810~µg/l, 95% CI for the median [745; 917] vs. OT 1230~µg/l [780; 1890], p = 0.006; SA: PT 46.2~mg/l [39.9; 54.4] vs. OT 70.4~mg/l [52.4; 89], p = 0.015) despite an identical SA dosing scheme.
CONCLUSIONS
SA plasma concentrations were found in the median 34% lower in pregnant women with PT compared to OT patients and fell below a lower reference value of 50~mg/l in a substantial portion of PT patients. The interindividual variability of plasma concentrations in combination with systematically lower drug levels and possibly a lower compliance in pregnant women may thus account for a still not yet supportable transmission risk. Systematic drug-level testing in PT under PY/SA treatment deserves to be considered.},

There are no pharmacological data on pregnant women with acute Toxoplasma gondii infection under treatment with pyrimethamine (PY) and sulfadiazine (SA) and our study intends to tighten this gap.
METHODS
In this retrospective case-control study, we included 89 pregnant women with primary Toxoplasma infection (PT) treated with PY (50~mg first dose, then 25~mg/day), SA (50~mg/kg of body weight/day), and folinic acid (10-15~mg per week). These were compared to a group of 17 women with acute ocular toxoplasmosis (OT) treated with an initial PY dose of 75~mg, thereafter 25~mg twice a day but on the same SA and folinic acid regimen. The exact interval between drug intake and blood sampling and co-medication had not been recorded. Plasma levels of PY and SA were determined 14 $pm$ 4~days after treatment initiation using liquid chromatography-mass spectrometry and compared using the Mann-Whitney U test at a p textless 0.05 level.
RESULTS
In 23 PT patients (26%), SA levels were below 20~mg/l. Fifteen of these 23 patients (17% of all patients) in parallel presented with PY levels below 700~µg/l. Both drug concentrations differed remarkably between individuals and groups (PY: PT median 810~µg/l, 95% CI for the median [745; 917] vs. OT 1230~µg/l [780; 1890], p = 0.006; SA: PT 46.2~mg/l [39.9; 54.4] vs. OT 70.4~mg/l [52.4; 89], p = 0.015) despite an identical SA dosing scheme.
CONCLUSIONS
SA plasma concentrations were found in the median 34% lower in pregnant women with PT compared to OT patients and fell below a lower reference value of 50~mg/l in a substantial portion of PT patients. The interindividual variability of plasma concentrations in combination with systematically lower drug levels and possibly a lower compliance in pregnant women may thus account for a still not yet supportable transmission risk. Systematic drug-level testing in PT under PY/SA treatment deserves to be considered.

Influenza vaccination was used to assess whether induction of immunity or side effects are influenced by the timing of the last training session before vaccination.
METHODS
Forty-five healthy athletes (36 male, 23 $pm$ 8 yr, $geq$5 training sessions per week, predominantly national competition level) were vaccinated with the tetravalent influenza vaccine; blood samples were collected immediately before and 1, 2, and 26 wk after vaccination. Athletes were randomly assigned to vaccination within 2 h after the last training session versus after 24-26 h. Influenza-specific T cells were quantified after stimulation with the vaccine based on intracellular cytokine staining. Antibodies (IgA, IgG, IgM) were quantified by enzyme-linked immunosorbent assay and neutralization assay. Participants documented resulting side effects and training restrictions using a standardized diary.
RESULTS
Both groups showed an increase in influenza-reactive CD4 T-cell levels, which peaked 1 wk after vaccination (fold changes to baseline; median (interquartile range), 3.7 (3.0-5.4; P textless 0.001) in the 2-h group; 4.6 (2.8-7.4; P textless 0.001) in the 26-h group) with no difference between groups (P = 0.52). Influenza-specific antibodies showed a significant increase after vaccination in both groups (at least 1.4-fold, each P textless 0.001, no group differences; P = 0.24-0.97 for different antibody types). Only antibodies toward the Brisbane strain showed a trend toward significant differences in neutralization titers between groups (4-fold (2-17.8) in the 2-h group, 16-fold (4-32.9) in the 26-h group; P = 0.06), whereas other specificities did not differ (P = 0.16-0.72). No intergroup differences were found for side effects; no athlete reported a loss of training time due to the vaccination or its side effects.
CONCLUSION
Infection prophylaxis in elite athletes by influenza vaccination seems to be effective and safe. Timing of vaccination after prior training does not seem to require specific constraints.},
