How do national immunization technical advisory groups assess and use evidence: Findings from the SYSVAC survey.

National immunization technical advisory groups (NITAGs) develop evidence-based vaccination recommendations. Systematic reviews (SRs) are important tools in that process, but conducting them is very resource-intensive. Given the considerable number of immunization-related SRs published and to minimize duplication of effort, a more practical approach for NITAGs is to use existing SRs.

Psychedelic-assisted therapy for treating anxiety, depression, and existential distress in people with life-threatening diseases.

Background: Psychedelic-assisted therapy refers to a group of therapeutic practices involving psychedelics taken under therapeutic supervision from physicians, psychologists, and others. It has been hypothesised that psychedelic-assisted therapy may reduce symptoms of anxiety, depression, and existential distress in patients facing life-threatening diseases (e.g.

Informing pandemic management in Germany with trustworthy living evidence syntheses and guideline development: lessons learned from the COVID-19 evidence ecosystem.

Objectives: We present the 'COVID-19 evidence ecosystem' (CEOsys) as a German network to inform pandemic management and to support clinical and public health decision-making. We discuss challenges faced when organizing the ecosystem and derive lessons learned for similar networks acting during pandemics or health-related crises.

Study Design And Setting: Bringing together 18 university hospitals and additional institutions, CEOsys key activities included research prioritization, conducting living systematic reviews (LSRs), supporting evidence-based (living) guidelines, knowledge translation (KT), detecting research gaps, and deriving recommendations, backed by technical infrastructure and capacity building.

Daratumumab and antineoplastic therapy versus antineoplastic therapy only for adults with newly diagnosed multiple myeloma ineligible for transplant.

Background: Multiple myeloma (MM) is a haematological malignancy that is characterised by proliferation of malignant plasma cells in the bone marrow. For adults ineligible to receive high-dose chemotherapy and autologous stem cell transplant, the recommended treatment combinations in first-line therapy generally consist of combinations of alkylating agents, immunomodulatory drugs, and proteasome inhibitors. Daratumumab is a CD38-targeting, human IgG1k monoclonal antibody recently developed and approved for the treatment of people diagnosed with MM.

Needs and feasibility of living systematic reviews (LSRs): Experience from LSRs on COVID-19 vaccine effectiveness.

During 2021 and 2023, a team of researchers at the Robert Koch Institute (RKI) and partnering institutions conducted two living systematic reviews (LSRs) on the effectiveness of COVID-19 vaccines in different age groups to inform recommendations of the Standing Committee on Vaccination in Germany (Ständige Impfkommission, STIKO). Based on our experience from the realization of these LSRs, we developed certain criteria to assess the needs and feasibility of conducting LSRs. Combining these with previously established criteria, we developed the following set to inform future planning of LSRs for STIKO: Needs criterion (N)1: Relevance of the research question, N2: Certainty of evidence (CoE) at baseline; N3: Expected need for Population-Intervention-Comparator-Outcome (PICO) adaptations; N4: Expected new evidence over time; N5: Expected impact of new evidence on CoE; Feasibility criterion (F)1: Availability of sufficient human resources; F2: Feasibility of timely dissemination of the results to inform decision-making.

[Development of criteria for the prospective assessment of the need for updating guideline recommendations: The AGIL criteria].

Background: Evidence-based guideline and vaccination recommendations should continuously be updated to appropriately support health care decisions. However, resources for updating guidelines are often limited. The aim of this project was to develop a list of criteria for the prospective assessment of the need for updating individual guideline or vaccination recommendations, which can be applied from the time a guideline or guideline update is finalised.

Methods and guidance on conducting, reporting, publishing, and appraising living systematic reviews: a scoping review.

Background And Objective: The living systematic review (LSR) approach is based on ongoing surveillance of the literature and continual updating. Most currently available guidance documents address the conduct, reporting, publishing, and appraisal of systematic reviews (SRs), but are not suitable for LSRs per se and miss additional LSR-specific considerations. In this scoping review, we aim to systematically collate methodological guidance literature on how to conduct, report, publish, and appraise the quality of LSRs and identify current gaps in guidance.

Convalescent plasma for people with COVID-19: a living systematic review.

Background: Convalescent plasma may reduce mortality in patients with viral respiratory diseases, and is being investigated as a potential therapy for coronavirus disease 2019 (COVID-19). A thorough understanding of the current body of evidence regarding benefits and risks of this intervention is required.

Objectives: To assess the effectiveness and safety of convalescent plasma transfusion in the treatment of people with COVID-19; and to maintain the currency of the evidence using a living systematic review approach.

First-line therapy for adults with advanced renal cell carcinoma: a systematic review and network meta-analysis.

Background: Since the approval of tyrosine kinase inhibitors, angiogenesis inhibitors and immune checkpoint inhibitors, the treatment landscape for advanced renal cell carcinoma (RCC) has changed fundamentally. Today, combined therapies from different drug categories have a firm place in a complex first-line therapy. Due to the large number of drugs available, it is necessary to identify the most effective therapies, whilst considering their side effects and impact on quality of life (QoL).

Safety and effectiveness of vaccines against COVID-19 in children aged 5-11 years: a systematic review and meta-analysis.

Background: To date, more than 761 million confirmed SARS-CoV-2 infections have been recorded globally, and more than half of all children are estimated to be seropositive. Despite high SARS-CoV-2 infection incidences, the rate of severe COVID-19 in children is low. We aimed to assess the safety and efficacy or effectiveness of COVID-19 vaccines approved in the EU for children aged 5-11 years.

The effectiveness of clinical guideline implementation strategies in oncology-a systematic review.

Importance: Guideline recommendations do not necessarily translate into changes in clinical practice behaviour or better patient outcomes.

Objective: This systematic review aims to identify recent clinical guideline implementation strategies in oncology and to determine their effect primarily on patient-relevant outcomes and secondarily on healthcare professionals' adherence.

Methods: A systematic search of five electronic databases (PubMed, Web of Science, GIN, CENTRAL, CINAHL) was conducted on 16 december 2022.

Hyperimmune immunoglobulin for people with COVID-19.

Background: Hyperimmune immunoglobulin (hIVIG) contains polyclonal antibodies, which can be prepared from large amounts of pooled convalescent plasma or prepared from animal sources through immunisation. They are being investigated as a potential therapy for coronavirus disease 2019 (COVID-19). This review was previously part of a parent review addressing convalescent plasma and hIVIG for people with COVID-19 and was split to address hIVIG and convalescent plasma separately.

Protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the omicron variant and severe disease: a systematic review and meta-regression.

Background: The global surge in the omicron (B.1.1.

Facing the Omicron variant-how well do vaccines protect against mild and severe COVID-19? Third interim analysis of a living systematic review.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant is currently the dominant variant globally. This third interim analysis of a living systematic review summarizes evidence on the effectiveness of the coronavirus disease 2019 (COVID-19) vaccine (vaccine effectiveness, VE) and duration of protection against Omicron.

Methods: We systematically searched literature on COVID-19 for controlled studies, evaluating the effectiveness of COVID-19 vaccines approved in the European Union up to 14/01/2022, complemented by hand searches of websites and metasearch engines up to 11/02/2022.

Immunity after COVID-19 vaccination in people with higher risk of compromised immune status: a scoping review.

Background: High efficacy in terms of protection from severe COVID-19 has been demonstrated for several SARS-CoV-2 vaccines. However, patients with compromised immune status develop a weaker and less stable immune response to vaccination. Strong immune response may not always translate into clinical benefit, therefore it is important to synthesise evidence on modified schemes and types of vaccination in these population subgroups for guiding health decisions.

Interventions to increase COVID-19 vaccine uptake: a scoping review.

Background: Vaccines are effective in preventing severe COVID-19, a disease for which few treatments are available and which can lead to disability or death. Widespread vaccination against COVID-19 may help protect those not yet able to get vaccinated. In addition, new and vaccine-resistant mutations of SARS-CoV-2 may be less likely to develop if the spread of COVID-19 is limited.

SARS-CoV-2-neutralising monoclonal antibodies to prevent COVID-19.

Background: Monoclonal antibodies (mAbs) are laboratory-produced molecules derived from the B cells of an infected host. They are being investigated as potential prophylaxis to prevent coronavirus disease 2019 (COVID-19).

Objectives: To assess the effects of SARS-CoV-2-neutralising mAbs, including mAb fragments, to prevent infection with SARS-CoV-2 causing COVID-19; and to maintain the currency of the evidence, using a living systematic review approach.

Janus kinase inhibitors for the treatment of COVID-19.

Background: With potential antiviral and anti-inflammatory properties, Janus kinase (JAK) inhibitors represent a potential treatment for symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. They may modulate the exuberant immune response to SARS-CoV-2 infection. Furthermore, a direct antiviral effect has been described.

Extension of the PRISMA 2020 statement for living systematic reviews (LSRs): protocol.

: While the PRISMA 2020 statement is intended to guide the reporting of original systematic reviews, updated systematic reviews, and living systematic reviews (LSRs), its explanation and elaboration document notes that additional considerations for updated systematic reviews and LSRs may need to be addressed. This paper reports the protocol for developing an extension of the PRISMA 2020 statement for LSRs. We will follow the EQUATOR Network's guidance for developing health research reporting guidelines.

Effectiveness, immunogenicity, and safety of COVID-19 vaccines for individuals with hematological malignancies: a systematic review.

The efficacy of SARS-CoV-2 vaccination in patients with hematological malignancies (HM) appears limited due to disease and treatment-associated immune impairment. We conducted a systematic review of prospective studies published from 10/12/2021 onwards in medical databases to assess clinical efficacy parameters, humoral and cellular immunogenicity and adverse events (AE) following two doses of COVID-19 approved vaccines. In 57 eligible studies reporting 7393 patients, clinical outcomes were rarely reported and rates of SARS-CoV-2 infection (range 0-11.
