We present a global analysis of the spread of recently emerged SARS-CoV-2 variants and estimate changes in effective reproduction numbers at country-specific level using sequence data from GISAID. Nearly all investigated countries demonstrated rapid replacement of previously circulating lineages by the World Health Organization-designated variants of concern, with estimated transmissibility increases of 29% (95% CI 24-33), 25% (95% CI 20-30), 38% (95% CI 29-48) and 97% (95% CI 76-117), respectively, for B.1.1.7, B.1.351, P.1 and B.1.617.2.We assessed the impact of COVID-19 on diagnostic services for tuberculosis (TB) by national reference laboratories in the WHO European Region.  https://www.selleckchem.com/products/reparixin-repertaxin.html  Of 35 laboratories, 30 reported declines in TB sample numbers, amounting up to > 50% of the pre-COVID-19 volumes. Sixteen reported reagent or consumable shortages. Nineteen reallocated ressources to SARS-CoV-2 testing, resulting in an overall increase in workload, largely without a concomitant increase in personnel (n = 14). This poses a risk to meeting the 2025 milestones of the End TB Strategy.This study presents the isolation of influenza A(H5N8) virus clade 2.3.4.4b from a poultry worker during an outbreak of highly pathogenic avian influenza A(H5N8) among chickens at a poultry farm in Astrakhan, Russia in December 2020. Nasopharyngeal swabs collected from seven poultry workers were positive for influenza A(H5N8), as confirmed by RT-PCR and sequencing. The influenza A(H5N8) virus was isolated from one of the human specimens and characterised. Sporadic human influenza A(H5)2.3.4.4. infections represent a possible concern for public health.BackgroundEssential health services, including for tuberculosis (TB), are being affected by public health and social measures (PHSM) introduced to control COVID-19. In many settings, TB resources, facilities and equipment are being redirected towards COVID-19 response.AimWe sought to assess the COVID-19 pandemic's impact on TB services in the World Health Organization (WHO) European Region.MethodsThe fifty-three European Region Member States were asked to report qualitative and quantitative data in quarter one and two (Q1 and Q2) 2020. TB notifications were triangulated with the severity score on domestic movement restrictions to assess how they may have influenced TB detection.ResultsTwenty-nine countries reported monthly TB notifications for the first half of 2019 and 2020. TB notifications decreased by 35.5% during Q2 2020 compared with Q2 2019, which is six-fold more than the average annual decrease of 5.1% documented during 2015-2019. The number of patients enrolled in rifampicin-resistant/multidrug-resistant TB treatment also decreased dramatically in Q2 2020, by 33.5%. The highest movement restriction severity score was observed between April and May 2020, which coincided with the highest observed decrease in TB notifications.ConclusionA decrease in TB detection and enrolment to treatment may cause increases in TB burden and threatens the Region's ability to reach the TB targets of the 2030 Sustainable Development Goals, still this might be mitigated with rapid restoration of TB services and the implementation of targeted interventions during periods with severe PHSM in place, such as those introduced in response to the COVID-19 pandemic.Residents in long-term care facilities (LTCF) experienced a large morbidity and mortality during the COVID-19 pandemic in Spain and were prioritised for early COVID-19 vaccination. We used the screening method and population-based data sources to obtain estimates of mRNA COVID-19 vaccine effectiveness for elderly LTCF residents. The estimates were 71% (95% CI 56-82%), 88% (95% CI 75-95%), and 97% (95% CI 92-99%), against SARS-CoV-2 infections (symptomatic and asymptomatic), and COVID-19 hospitalisations and deaths, respectively.In the early stages of the COVID-19 pandemic, there were shortages of personal protective equipment (PPE) and healthcare personnel across severely affected regions. Along with a lack of testing, these shortages delayed surveillance, and possible containment of the virus. The pandemic also took unprecedented tolls on the mental health of many healthcare workers who treated and witnessed the deaths of critically ill patients. To address these effects and prepare for a potential second wave, a literature review was performed on the response of healthcare systems during the Influenza pandemics of 1918, 1957, 2009, and the epidemics of Ebola, Severe Acute Respiratory Syndrome (SARS), and Middle East Respiratory Syndrome (MERS). We can use lessons identified to develop a competent and effective response to the current and future pandemics. The public must continue to engage in proper health mitigation strategies including utilization of face coverings, physical distancing, and hand washing. The impact the pandemic has had on the mental health of frontline healthcare workers cannot be disregarded as it is essential in ensuring effective patient care and mitigating psychological comorbidities. The lessons identified from past public health crises can help contain and limit morbidity and mortality with the ongoing COVID-19 pandemic.Besides the inhibition of monoamine-oxidase-B, high-dose safinamide (100 mg) also blocks voltage-gated Na+ and Ca++ channels and inhibits glutamate release at overactive synapses. This latter mechanism may provide further benefit to fluctuating Parkinson's disease (PD) patients compared to rasagiline. Here, we retrospectively investigated the consequences of shifting from rasagiline to high-dose safinamide in PD patients reporting symptoms of wearing-off, defined by the Wearing-Off-Questionnaire-19 (WOQ-19) score ≥3 at baseline. Seventeen PD patients were switched from rasagiline 1 mg to safinamide 100 mg because of the report of symptoms of fluctuations while under therapy with either levodopa+rasagiline or levodopa+rasagiline+dopamine agonists, or re-occurrence of fluctuations previously corrected by add-on with rasagiline. Patients were re-evaluated 4-6 months after switch. Switch to safinamide 100 mg produced benefit in 9/17 (52.9%) subjects, together with significant reduction of subjective symptoms of wearing-off.
