Long-COVID-19 clinical and health outcomes: an umbrella review.

Background: A growing interest in long-term sequelae of COVID-19 has prompted several systematic literature reviews (SLRs) to evaluate long-COVID-19 effects. However, many of these reviews lack in-depth information on the timing, duration, and severity of these conditions.

Objectives: Our aim was to synthesize both qualitative and quantitative evidence on prevalence and outcomes of long-term effect of COVID-19 through an umbrella review.

Early Real-World Data to Assess Benefits and Risks of COVID-19 Vaccines: A Systematic Review of Methods.

Since the authorization of the first COVID-19 vaccines in December 2020, multiple studies using real-world data (RWD) have been published to assess their effectiveness/safety profile. This systematic review aimed to characterize the methods and outcomes of studies using RWD for assessment of COVID-19 vaccines, four months after vaccine approval. MEDLINE and EMBASE were searched to identify published studies until 6 May 2021.

Neurosurgical resection for locally recurrent brain metastasis.

Background: In patients with locally recurrent brain metastases (LRBMs), the role of (repeat) craniotomy is controversial. This study aimed to analyze long-term oncological outcomes in this heterogeneous population.

Methods: Craniotomies for LRBM were identified from a tertiary neuro-oncological institution.

Quantifying the impact of surgical decompression on quality of life and identification of factors associated with outcomes in patients with symptomatic metastatic spinal cord compression.

Objective: Metastatic spinal cord compression (MSCC) imposes significant impairment on patient quality of life and often requires immediate surgical intervention. In this study the authors sought to estimate the impact of surgical intervention on patient quality of life in the form of mean quality-adjusted life years (QALY) gained and identify factors associated with positive outcomes.

Methods: The authors performed a retrospective chart review and collected data for patients who had neurological symptoms resulting from radiologically and histologically confirmed MSCC and were treated with surgical decompression during the last 12 years.

Adult spinal deformity surgery: a systematic review of venous thromboprophylaxis and incidence of venous thromboembolic events.

Venous thromboprophylaxis consisting of chemical and/or mechanical prophylaxis is administered to patients undergoing adult spinal deformity (ASD) surgery to prevent venous thromboembolic events. However, the true incidence of venous thromboembolism (VTE) after these surgeries is unknown resulting in weak recommendations and lack of consensus regarding type and timing of prophylaxis in these patients. A systematic literature review was conducted to examine VTE incidence in addition to optimal type and timing of VTE prophylaxis.
