We explored whether initial treatment with the herbal drug uva ursi (UU) reduces antibiotic use in women with uncomplicated urinary tract infection (UTI) without increasing symptom burden and complication frequency compared with antibiotic treatment.

A double-blind randomized controlled trial was conducted in 42 family practices in Germany. The participants were adult women with suspected uncomplicated UTIs receiving either UU 105 mg 3×2 tablets for 5days (intervention) or fosfomycin a 3-g single dose (control), and their respective placebos. Participants and investigators were blinded. The primary outcome included (1) antibiotic courses day 0-28 as superiority, and (2) symptom burden (sum of daily symptom scores) day 0-7, as non-inferiority outcome (margin 125%). Clinicaltrials.gov NCT03151603.

Overall, 398 patients were randomly allocated to groups receiving UU (n=207) and fosfomycin (n=191). The number of antibiotic courses was 63.6% lower (95% CI 53.6%-71.4%; p<0.0001) in the UU group than in the fosfomycin group. The ratio of total symptom burden in the UU group compared with control was 136.5% (95% CI 122.7-151.9; p 0.95), failing non-inferiority. Eight women developed pyelonephritis in the UU group compared with two in the fosfomycin group (mean difference 2.8; 95% CI 0.2-5.9; p 0.067). Adverse events were similar between the groups.

In women with uncomplicated UTIs, initial treatment with UU reduced antibiotic use but led to a higher symptom burden and more safety concerns than fosfomycin.

To analyse the correlation between COVID-19 vaccination percentage and socioeconomic status (SES).

A nationwide ecologic study based on open-sourced, anonymized, aggregated data provided by the Israel Ministry of Health. The correlations between municipal SES, vaccination percentage and active COVID-19 cases during the vaccination campaign were analysed by using weighted Pearson correlations. To assess the adequacy of first dose vaccination rollout relative to the municipality COVID-19 disease burden, a metric termed the vaccination need ratio was devised by dividing the total number of active cases (per 10000 people) by the vaccination percentage of the population over 60 in each municipality, and its correlation with the SES was examined.

23days after initiation of the vaccination campaign, 760916 (56.8%) individuals over the age of 60 were vaccinated in Israel with the first dose of the BNT162b2 COVID-19 vaccine. A negative correlation was found between the COVID-19 active case burden and the vaccination percentage of the study population in each municipality (r=-0.47, 95% CI -0.59 to -0.30). The vaccination percentage significantly correlated with the municipal SES (r=0.83, 95% CI 0.79 to 0.87). This finding persisted but was attenuated over a 5-week period. A negative correlation between the vaccination need ratio and municipal SES (r=-0.80, 95% CI -0.88 to -0.66) was found.

Lower COVID-19 vaccination percentage was associated with lower SES and high active disease burden. Vaccination efforts should focus on areas with lower SES and high disease burden to assure equality of vaccine allocation and potentially provide a more diligent disease mitigation.

To evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, hospitalization and fatality rates in residents of homeless shelters run by Samusocial of Paris.

We conducted a retrospective serological study between July and August 2020 on all residents and staff members of three homeless shelters run by Samusocial of Paris two centres providing healthcare accommodation (HCA) and one a women's dormitory. We included all adults present in the shelters or who died of a proven SARS-CoV-2 infection during the first wave (March-May). SARS-CoV-2 antibodies were detected in serum samples using the SARS-CoV-2 IgG Architect (Abbott) test. Any participant with a positive PCR or serology was defined as a confirmed SARS-CoV-2 case.

We included 100 residents and 83 staff members. The confirmed SARS-CoV-2 rate by PCR or serology was 72/100 (72.0%) for residents and 17/83 (20.5%) for staff members. Women accommodated in the dormitory had the highest infection rate (90.6%). The hospitalization rate at risk.
Appropriate laboratory diagnostics for emerging arboviruses are key for patient management, surveillance and intervention, including molecular tests and serological tests detecting viral antigen or virus-specific antibodies.

We provide an overview of the challenges towards serological testing for the most important emerging arboviruses, including Zika, dengue and chikungunya viruses.

We retrieved a data set on performance of commercially available antibody- and antigen-detecting tests from 89 peer-reviewed articles conducting a systematic literature research in PubMed.

We identified commonly used antibody- and antigen-detecting tests and analysed their overall performance. GSK1210151A datasheet We discuss how timing of serological testing and the use of paired samples from acute and convalescent phases of infection are crucial to optimize diagnostic sensitivity and specificity. We then exemplify how serological diagnostics are challenged by the patient's infection history through the 'original antigenic sin' and cross-reacl spread of (re-)emerging viruses requires careful implementation and evaluation of serological testing and unambiguous results may not always be achievable.
For reliable serological diagnostics, it is essential to be aware of inherent test limitations. Although multiplexed testing and testing of convalescence samples can improve diagnostic performance, global spread of (re-)emerging viruses requires careful implementation and evaluation of serological testing and unambiguous results may not always be achievable.
