European neonates receive a number of potentially harmful pharmaceutical excipients. Regional differences in EOI administration suggest that EOI-free products are available and provide the potential for substitution to avoid side effects of some excipients.

SARS-CoV-2 antibody tests are available in various formats, detecting different viral target proteins and antibody subclasses. The specificity and sensitivity of SARS-CoV-2 antibody tests are known to vary and very few studies have addressed the performance of these tests in COVID-19 patient groups at different time points. We here compared the sensitivity and specificity of seven commercial (SNIBE, Epitope, Euroimmun, Roche, Abbott, DiaSorin, Biosensor) and two in-house LIPS assays (LIPS N and LIPS S-RBD) IgG/total Ab tests in serum samples from 97 COVID-19 patients and 100 controls, and correlated the results with the patients’ clinical data and the time-point the test was performed. We found a remarkable variation in the sensitivity of antibody tests with the following performance: LIPS N (91.8%), Epitope (85.6%), Abbott and in-house LIPS S-RBD (both 84.5%), Roche (83.5%), Euroimmun (82.5%), DiaSorin (81.4%), SNIBE (70.1%), and Biosensor (64.9%). The overall agreement between the tests was between 71–95%, whereas the specificity of all tests was within 98–100%. The correlation with patients’ clinical symptoms score ranged from strongest in LIPS N (ρ = 0.41; p<0.001) to nonsignificant in LIPS S-RBD. Furthermore, the time of testing since symptom onset had an impact on the sensitivity of some tests. Our study highlights the importance to consider clinical symptoms, time of testing, and using more than one viral antigen in SARS-CoV-2 antibody testing. Our results suggest that some antibody tests are more sensitive for the detection of antibodies in early stage and asymptomatic patients, which may explain the contradictory results of previous studies and should be taken into consideration in clinical practice and epidemiological studies.

The reported rates of STI in many eastern European countries have either decreased (syphilis and gonorrhoea in the eastern/Russian regions, gonorrhoea throughout eastern Europe) or been relatively stable (syphilis in the southeastern region, chlamydia throughout eastern Europe), in the past decade, but are still significantly higher than in western Europe. There is a significant east-west geopolitical gradient in reported STI rates throughout eastern Europe (STI rates: Russia/eastern region>>southeastern region>central region). Challenges for STI control include: the need to strengthen public health components of control; improvements in surveillance and improvement, as well as quality assurance, in diagnostic strategies. Gains in STI control may be achieved through greater collaboration and harmonisation of practicss at the European level.

AimsTo estimate the prevalence of urinary incontinence (UI) and to assess its risk factors among postmenopausal Estonian women.MethodsIn 2004, 1363 women participating in the Estonian Postmenopausal Hormone Therapy Trial were asked at the closure visit to the trial physician about symptoms of UI. The type of incontinence was assessed with the help of a questionnaire, based on recommendations from the working group set up by the Finnish Gynaecological Association. Frequency characteristics were analysed by descriptive statistics. Risk factors were examined using logistic regression.ResultsMean age of study women was 53.3 years (min = 48, max = 67; SD 4.0). The prevalence of UI was 18.12% (95% CI: 16.07 - 20.17). Stress incontinence was diagnosed in 78.83% (95% CI: 73.32 - 84.33) and urge or mixed incontinence in 21.17% (95% CI: 15.67 - 26.68) of women who reported incontinence. Prevalence of UI slightly increased with age. Women who used hormone therapy (HT) (OR 1.67; 95% CI: 1.17 - 2.39), had had hysterectomy (1.73, 95% CI: 1.06 - 2.83), and those with secondary education (OR 1.87, 95% CI: 1.23 - 2.82) or basic education (OR 3.29, 95% CI: 1.80 - 6.02) had a higher risk for UI. Parity, having a BMI over 30 kg/m2, being a smoker or a former smoker, having diabetes and being physically or sexually active, tended to increase the risk of UI.ConclusionsAbout one in five postmenopausal women in Estonia reported to have UI. Risk factors linked with UI, its prevalence in other age groups and the impact of UI on quality of life deserve more research.Trial registrationNumber: ISRCTN35338757

The clinical features of SARS-CoV-2 infection range from asymptomatic to severe disease with life-threatening complications. Understanding the persistence of immune responses in asymptomatic individuals merit special attention because of their importance in controlling the spread of the infections. We here studied the antibody and T cell responses, and a wide range of inflammation markers, in 56 SARS-CoV-2 antibody-positive individuals, identified by a population screen after the first wave of SARS-CoV-2 infection. These, mostly asymptomatic individuals, were reanalyzed 7-8 months after their infection together with 115 age-matched seronegative controls. We found that 7-8 months after the infection their antibodies to SARS-CoV-2 Nucleocapsid (N) protein declined whereas we found no decrease in the antibodies to Spike receptor-binding domain (S-RBD) when compared to the findings at seropositivity identification. In contrast to antibodies to N protein, the antibodies to S-RBD correlated with the viral neutralization capacity and with CD4+ T cell responses as measured by antigen-specific upregulation of CD137 and CD69 markers. Unexpectedly we found the asymptomatic antibody-positive individuals to have increased serum levels of S100A12, TGF-alpha, IL18, and OSM, the markers of activated macrophages-monocytes, suggesting long-term persistent inflammatory effect associated with the viral infection in asymptomatic individuals. Our results support the evidence for the long-term persistence of the inflammation process and the need for post-infection clinical monitoring of SARS-CoV-2 infected asymptomatic individuals.

ObjectivesTo assess HIV/AIDS research productivity in the 27 countries of the European Union (EU), and the structural level factors associated with levels of HIV/AIDS research productivity.MethodsA bibliometric analysis was conducted with systematic search methods used to locate HIV/AIDS research publications (period of 1 January 2002 to 31 December 2011; search databases: MEDLINE (Ovid, PubMed), EMBASE, ISI-Thomson Web of Science; no language restrictions).The publication rate (number of HIV/AIDS research publications per million population in 10 years) and the rate of articles published in HIV/AIDS journals and selected journals with moderate to very high (IF ≥3) 5-year impact factors were used as markers for HIV research productivity. A negative binomial regression model was fitted to assess the impact of structural level factors (sociodemographic, health, HIV prevalence and research/development indicators) associated with the variation in HIV research productivity.ResultsThe total numbers of HIV/AIDS research publications in 2002–2011 by country ranged from 7 to 9128 (median 319). The median publication rate (per million population in 10 years) was 45 (range 5–150) for all publications. Across all countries, 16% of the HIV/AIDS research was published in HIV/AIDS journals and 7% in selected journals with IF ≥3. Indicators describing economic (gross domestic product), demographic (size of the population) and epidemiological (HIV prevalence) conditions as well as overall scientific activity (total research output) in a country were positively associated with HIV research productivity.ConclusionsHIV research productivity varies noticeably across EU countries, and this variation is associated with recognisable structural factors.
